Introduction:Primary Sjögren’s syndrome(pSS) is an idiopathic, autoimmune disorder characterized by both localized and systemic manifestations. The most common clinical presentations include the “sicca” or “dryness” symptoms such as xerostomia and keratoconjunctivitis sicca due to diminished salivary gland and lacrimal gland function, respectively. Patients may also present with nonspecific symptoms such as fatigue and arthralgia, as well as pulmonary, gastrointestinal, neurological and renal involvement.1 Secondary Sjogren’s syndrome can coexist with other autoimmune disorders such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). 2According to literature, ocular signs and symptoms in pSS range from foreign body sensations, punctate or filamentous keratitis, to overt seborrheic blepharitis and eyelid swelling is reported to be rare.3 We report an usual/rare presentation of Sjogren’s syndrome in which the patient developed severe evolving mechanical ptosis and eyelid swelling to the extent that it impaired her ability to lift open her eyes and see, along with a positive anti-acetylcholine receptor antibody test.

Ferroptosis is a newly discovered form of iron-dependent cell death caused by excessive lipid peroxidation. It is widely involved in a variety of pathological processes in the body and has been considered to be related to the development and treatment of various diseases. The study of extracellular vesicles has also advanced significantly over the past ten years, transitioning from a field of fundamental biological study to one with significant clinical implications. It is also presently actively investigating its potential use as a brand-new drug delivery system, combination therapy, etc. Research on ferroptosis mediated by extracellular vesicles has made progress in disease treatment. Given this, this review will focus on the association of extracellular vesicles with ferroptosis and the role that it mediates in the disease. Firstly, a description of ferroptosis' primary mechanisms is provided. Secondly, the pathways associated with ferroptosis and extracellular vesicles are elaborated, with attention to the relevance of the corresponding mechanisms to disease and potential applications for therapeutic use. Finally, future expectations and challenges of targeting the extracellular vesicle-mediated ferroptosis pathway in disease treatment are discussed.

Nacelle-mounted, forward-facing LIDAR technology is able to deliver benefits to rotor speed regulation and loading reductions of floating offshore wind turbines when assisting with blade pitch control in above-rated wind speed conditions. Large-scale wind turbines may be subject to significant variations in structural loads due to differences in the wind profile across the rotor-swept area. These loading fluctuations can be mitigated through the use of individual blade pitch control (IPC). This paper presents a novel LIDAR-assisted feedforward IPC approach that uses each blade’s rotor azimuth position to allocate an appropriate individual pitch command from a multi-beam LIDAR. In this computational study, the source code of OpenFAST wind turbine modelling software was modified to enable LIDAR simulation and LIDAR-assisted control. The LIDAR simulation modifications made are present in the latest OpenFAST release, v3.5. Simulations were performed on a single 15 MW floating offshore wind turbine across the above-rated wind spectrum and using multiple randomly generated wind profiles. Under a turbulent wind field with an average wind speed of 17 ms -1, the LIDAR-assisted feedforward IPC delivered root mean squared error and standard deviation reductions to key turbine and substructure parameters by up to 35%. Feedforward IPC delivered enhancements of up to 10% over feedforward collective pitch control, which instead provided the same feedforward command to all blades, compared to the baseline feedback controller. The reductions to the standard deviation and range of the rotor speed may enable structural optimisation of the tower, while the reductions in the variations in the loadings present an opportunity for reduced fatigue damage on turbine components and, consequently, a reduction in maintenance expenditure.

Plant virus disease is one of the most threatening diseases in agricultural production, and the availability of effective drugs against viral diseases remains limited. Here, we discovered that betulinic acid (BA), a pentacyclic triterpenoid derived from natural plants, exhibits stable resistance to turnip mosaic virus (TuMV) in Nicotiana benthamiana. Through transcriptomic analysis and RT-qPCR assay, we have demonstrated that BA treatment specifically induces the expression of phytosulfokine 3 (PSK3), a plant pentapeptide hormone that fulfills a wide range of functions, while TuMV infection suppresses its expression. Further study showed that NbPSK3 positively regulates TuMV infection. Disruption of PSK signaling by targeting the membrane-bound PSK receptors (PSKRs) also promotes viral infection. Furthermore, exogenous PSK treatment could significantly enhance the resistance of N. benthamiana to TuMV compared with the dPSK or control treatments, and the silencing receptor NbPSKR1 abolishes the ability of PSK to inhibit TuMV infection. Meanwhile, BA inhibition of TuMV infection is dependent on PSK-PSKR signaling pathway. Overall, these results not only highlight the potential of BA as a promising and environmentally friendly agent for preventing plant viral diseases but also emphasize the importance of the PSK signaling pathway in enhancing TuMV resistance for crop improvement.

Lyme borreliosis (LB) is the most common vector-borne disease in the Northern Hemisphere caused by spirochetes belonging to the Borrelia burgdorferi sensu lato (Bbsl) complex. Borrelia spirochetes circulate in obligatory transmission cycles between tick vectors and different vertebrate hosts. To successfully complete this complex transmission cycle, Bbsl encode for an arsenal of proteins including the PFam54 protein family with known, or proposed, influences to reservoir host and/or vector adaptation. Even so, only fragmentary information is available regarding the naturally occurring level of variation in the PFam54 gene array and its impact on Borrelia pathogenesis. Utilizing whole genome data from isolates (n=141) originated from the three major LB-causing Borrelia species across Eurasia (B. afzelii, B. bavariensis, and B. garinii), we aimed to characterize the diversity of the PFam54 gene array in these isolates to facilitate understanding the evolution of PFam54 orthologs on an intra- and interspecies level. We found an extraordinarily high level of variation in the PFam54 gene array with 39 PFam54 paralogs belonging to 23 orthologous groups including five novel paralogs. Even so, the gene array appears to have remained fairly stable over the evolutionary history of these Borrelia species. Interestingly, genes outside Clade IV previously associated with host or, proposed, vector adaptation more frequently displayed signatures of diversifying selection. Taken together, our findings support the idea that non-Clade IV orthologs could play a larger role in host and/or vector adaptation than previously thought.

The costs of foraging can be high while also carrying significant risks. To mitigate these risks, many predators supplement active hunting with scavenging and kleptoparasitism, in some cases specializing in these alternative modes of predation. However, the factors that drive differential utilization of these strategies are not well understood. Here we use an energetics approach to investigate the fitness advantages of hunting, scavenging, and kleptoparasitism as a function of predator, prey, and competitor body sizes for terrestrial mammalian carnivores. Our results reveal that predator strategies become more diverse with declining body condition, while the deployment of scavenging and kleptoparasitism is strongly constrained by the ratio of predator to prey body size. Our model accurately predicts a behavioral transition away from hunting towards alternative modes of predation with increasing prey size for predators spanning an order of magnitude in body size, closely matching observational data across a range of species.

Life histories are predicted to evolve when the age schedules of mortality shift due to top-down forces such as predation. Theory on how competitive interactions alter the life history is rare. We use an explicit consumer-resource model to show that changes in the way organisms interact with their resources and changes in the properties of those resources can alter the optimal life history of a consumer. When older/larger organisms are better competitors, delayed maturity can be favored. When older/larger individuals are better competitors but also shift their resource use with age or size, alternative life histories are possible. We further show that when two species compete for shared resources, selection tends to make the life histories of the two competitors more similar. These results, some of which are opposite to predictions from traditional theory, illustrate the importance of incorporating explicit interactions between trophic levels into models for life history evolution.

Tridacna maxima (T. maxima) are widely distributed in shallow areas near coral reefs and hold significant commercial value as a food source and for marine tourism. However, it has been extensively harvested and depleted in many regions, leading to it being listed as endangered species by the International Union for Conservation of Nature (IUCN). While marine protected areas (MPAs) are considered effective conservation tools, it remains uncertain whether existing MPAs adequately protect these vulnerable giant clams. Here, we employed a Species Distribution Models (SDMs) approach, combining occurrence records of T. maxima with environmental variables, to predict their distribution and capture spatiotemporal changes. The findings revealed the importance of land distance and light at bottom in determining the distribution of T. maxima, with suitable habitats predominantly found in shallow coastal waters rather than deep sea areas. Furthermore, we modeled potential distribution areas for T. maxima in 2050 and 2100 under different climate change scenarios, highlighting varying impacts on suitable habitats across different model predictions. To evaluate current conservation gaps, we conducted an analysis by overlaying suitable areas with existing protected areas. The results showed that the potential distribution area of T. maxima is 1,519,764.73 km2, accounting for only 16.10% of the total protected areas. It became evident that the existing protected areas are insufficiently large or well-connected, suggesting their ineffectiveness in safeguarding giant clams. Therefore, management efforts should focus on establishing a network of MPAs along the coastlines of West Pacific-Indonesia, matching the dispersal capability of giant clams. These findings provide valuable insights for the conservation of endangered giant clams, offering a scientific foundation for designing MPA networks in the Indo-Pacific region.

Viral diseases are the primary cause of disease and economic loss in all bird species. Among viral diseases, Newcastle disease (ND) and Avian Influenza (AI) have a very special place due to their high morbidity and high mortality. They inflict lots of deaths and economic losses upon poultry and nonpoultry avian species, making them a hot subject in various research. Thus, prevention measures and strategies to control the mentioned diseases are wide. Vaccination is one of the common methods. In this study we designed a vaccination protocol based on previous and popular methods to evaluate the effect of ND and AI vaccines on humoral immune response of 14 bird species. We tested 115 birds (sampled twice) with no previous encounter to disease or vaccine. Birds were vaccinated with NDV B1 strain and a bivalent inactivated ND+AI, and repeated 5 weeks later. HI was used for humoral response evaluation and implemented 5 weeks post each vaccination. Our results showed a double vaccination of ND is can boost immune system significantly, but a single AI vaccination will provide enough protection, since the second vaccination did not change the titers significantly, even lowered titer in one case. There were some discrepancies in results which further studies should be accomplished to elaborate the details.

Body size shifts in ectotherms are mostly attributed to the Temperature Size Rule stating that warming speeds up initial growth rate but leads to smaller size when food availability does not limit growth. Nevertheless, climate warming can decrease food availability, which can influence growth, fecundity and survival. However, the interactive effects of temperature and food availability on life history traits have been mostly studied in small invertebrate species. In contrast, we have limited information on how temperature and food availability jointly influence life history traits in vertebrate predators and how changes in different life history traits combines to influence population demography. We investigated the independent and interactive effects of temperature and food availability on traits of the medaka fish Oryzias latipes. We used our empirical estimates of vital rates as input parameters of an Integral Projection model to predict how modifications in vital rates translate into population demography. Our results confirm that warming leads to a higher initial growth rate and lower size leading to crossed growth curves between the two temperatures. Food-restricted fish were smaller than ad libitum fed fish throughout the experiment. Fish reared at 30 °C matured younger, had smaller size at maturity, had a higher fecundity but had a shorter life span than fish reared at 20 °C. Food restriction increased survival under both temperature conditions. Warming reduces generation time and increases mean fitness in comparison to the cold treatments. Food restriction increased generation time and fitness in the cold treatment but had no effect in the warm treatment. Our results highlight the importance of accounting for the interaction between temperature and food availability to understand how body size shifts can affects vital rates and population demography. This is of importance in the context of global warming as resources are predicted to change with increasing temperatures.

This paper is concerned with quantum stochastic differential equations driven by the fermion field in noncommutative space L p ( C ) for p>2. We investigate the existence and uniqueness of L p -solution of quantum stochastic differential equations in infinite time horizon by the Burkholder-Gundy inequalities for noncommutative martingales given by Pisier and Xu. Finally, we obtain Markov property and the self-adjointness which is of great significance in the study of optimal control problems. 2020 AMS Subject Classification: 46L51, 47J25, 60H10, 81J25.

This work mainly concerned on the optical soliton solutions and chaotic pattern for the coupled stochastic Schrödinger-Hirota equation with multiplicative white noise in magneto-optic waveguides. Firstly, by means of traveling wave transformations and homogeneous balance principle, the the coupled stochastic Schrödinger-Hirota equation in magneto-optic waveguides is transformed into ordinary differential equation. By selecting some suitable parameters, phase diagrams are plotted with the help of the mathematical software Maple. Secondly, the optical soliton solutions of the coupled stochastic Schrödinger-Hirota equation corresponding to phase orbits can be easily deduced through the method of dynamical systems. Finally, the two-dimensional and three-dimensional graphs of the stochastic Schrödinger-Hirota equation are drawn, which further explain the propagation of the coupled stochastic Schrödinger-Hirota equation in nonlinear optics.

In this article, the Adomian Decomposition Method (ADM) and Modified Adomian Decomposition Method (MADM) are introduced to provide the approximate solutions for Volterra-Fredholm Integro-differential equations. Moreover, we prove the existence and uniqueness results and convergence of the solutions. To arrive at that conclusion, an algorithm is used. Additionally, examples of deterministic models in graphs and tables are used to perform the convergence analysis of the proposed technique.

Purpose: In 2005, the Food and Drug Administration (FDA) issued a decision memorandum regarding nonsteroidal anti-inflammatory drugs (NSAIDs). The memorandum recommended the withdrawal of certain NSAIDs due to potential cardiovascular adverse effects. It highlighted the issue of cardiovascular risk associated with NSAIDs as a class. The NSAID medication guide includes a wide range of adverse drug reactions (ADRs), such as increased blood pressure, liver failure, allergic reactions, heart attack, and intestinal bleeding. Although both sexes have an increased risk of ADRs with NSAID use, females have a greater risk than males due to differences in pharmacodynamics and higher medication concentrations (mg/kg). The prevalence of NSAIDs and the disparity in risk of ADRs by sex within this class of medications make this a significant public health issue. This study quantifies sex-specific differences and other factors associated with prescription NSAID use. Method: The data for this study was obtained from the National Health and Nutrition Examination Survey (NHANES), a complex survey conducted by the Centers for Disease Control and Prevention (CDC) in two-year cycles. NHANES is designed to make inferences about the health of the US civilian noninstitutionalized population. A survey-weighted logistic regression model was utilized to investigate potential sex differences with prescription NSAIDs in the context of other factors including kidney disease, hypertension, liver disease, insurance status, coronary heart disease, and age within the 2011-2018 NHANES survey data. Results: Females reported a slightly higher percentage of high blood pressure and kidney disease than males, while males reported a slightly higher percentage of coronary heart and liver disease than females. Furthermore, a larger percentage of females reported having health insurance coverage than males. Last, the model indicated that females were 58% more likely to have used a prescription NSAID than males. Conclusion: The results confirm that women and people with medical conditions, who would potentially suffer greater harm from NSAID ADRs, are more likely to use a prescription NSAID than individuals without these conditions. Therefore, it is crucial to continue investigating the safety and efficacy of medications, particularly in specific populations, to reduce the risk of harmful side effects from medication use.

Evolution occurring over ecological time scales can affect community functions both directly and indirectly, via changes in community composition. This interplay between ecology and evolution makes identifying the role of rapid evolution in shaping the functioning of complex natural communities challenging. We used a methanogenic community from an anaerobic digester to investigate the potential importance of rapid evolution in shaping community methane production. To disentangle evolutionary and ecological processes, we pre-adapted the community to a novel feedstock in laboratory anaerobic fermenters for 6 weeks and then inoculated 1% back into the ancestral community. This allowed the introduction of any within-taxa genetic changes that occurred over the pre-adaptation period, while minimally altering the taxonomic composition of the community. The addition of the pre-adapted inoculum increased biogas production by ~10% over 6 weeks compared to a control treatment without the addition, with the corresponding minor changes in community composition unable to explain this increase. These findings suggest that rapid adaptive evolution can play an important role in shaping the structure and function of natural microbial communities and provide a novel approach to enhancing microbial community functions.

Since a magic “polypill” – the “Environment-Sleep-Emotion-Exercise-Diet” intervention [E(e)SEEDi] was discovered in 2018, it plays a pivotal role in control and prevention of human disease due to improvement of immunity by healthy lifestyle. It can be said that it is applicable, as long as one is a human and survival. However, do plants also need the magic “polypill”? When plants need a suitable environment, rational internal exercise, and balancing nutrients (fertilizers, herbicides, nutrients, pesticides, and others), do they also need sleep? And have also emotions like humans? These are interesting questions. Currently, obvious climate change threats herbal cultivation in both China and the globe, in particular the pandemic and post-COVID-19 era. Only when we understand and confirm that plants also need sleep and have emotions, can we better protect medicinal plants and promote herb cultivation and healthy growth, since traditional Chinese herbs have a good efficacy in combating cardiovascular disease.

Plants store chemical defenses that act as toxins to herbivores, such as toxic isothiocyanates (ITCs) in Brassica plants, hydrolyzed from the precursor glucosinolates (GLSs). Fitness of herbivorous larvae can be highly affected by these toxins, causing immature deaths. Theoretically, toxins can inordinately reduce larval fitness to death. We model this phenomenon by a set of ordinary differential equations and establish a direct relationship between feeding, toxin exposure and net energy of a larva, where the fitness of an organism is proportional to its net energy according to the optimal foraging theory. Our equations explain that toxin exposure can steeply reduce larval net energy to zero at an instar stage. Since herbivory needs energy, the only choice left for a larva is to stop feeding at the time point. If that time-point is significantly earlier than the end of the last instar stage, the larva dies.

Ecologists are increasingly interested in the deterministic factors that influence microbial communities. Yet in comparison to other microbes, our understanding of viral community ecology is limited. Here we investigated the factors influencing the community ecology of picobirnaviruses among wild rhesus macaques (Macaca mulatta) in Bangladesh. Using co-occurrence networks and species distribution models, we found that macaques’ social organisation and anthropogenic factors (human and livestock densities) had the greatest impact on picobirnavirus communities. Virus phylogenetic relationships, host demographics (sex, age), and host physiological stress (cortisol levels) had less of an impact. We also found a few significant biotic virus-virus associations that impacted community composition, more so at lower host social organisational levels (individual macaques within groups) compared to higher levels (macaque groups within sites). These findings advance our understanding of the deterministic factors shaping viral communities, and contribute to changing perceptions of viruses as embedded components of human-natural ecosystems.

Parental investment comes with increased fitness costs, often expressed as negative effects on survival and future reproduction. We used a novel approach to experimentally alter reproductive investment in a wild bird population and measured telomere length before and after breeding to better understand the costs of reproduction and life history trade-offs. Telomeres are terminal features of chromosomes consisting of highly conserved DNA repeats that shorten with age and stress and whose length is positively correlated with lifespan. We assessed the effects of calcium supplementation on reproductive parameters and telomere length in Tree Swallows (Tachycineta bicolor) in northern Colorado. Measuring telomere length at the beginning and end of each breeding season facilitated evaluation of changes exclusively caused by maternal investment in reproduction. We found that Tree Swallows supplemented with calcium had higher reproductive success and greater telomere shortening compared to control birds. Although mothers supplemented with calcium suffered increased telomere attrition, offspring in calcium supplemented nests had longer telomeres at 12 days old. Thus, Tree Swallow mothers supplemented with calcium had higher reproductive output and offspring with longer telomeres yet these mothers suffered the cost of lower expected maternal lifespan, as indicated by shorter telomeres during the reproductive season.

How to ventilate critical children with cancer?Jesus Dominguez-Rojas M.D.1, Silvio Fabio Torres Godoy M.D.2, Lupe Nataly Mora Robles MD3, Ale Méndez Aceituno MD4.1. Medico Pediatra Intensivista.

It is worth mentioning that children with malignant neoplasms usually have low priority for admission to Pediatric Intensive Care Units (PICU), since the allocation of beds to these children with cancer is considered to have a poor prognosis. It is for this reason that the usefulness of invasive mechanical ventilation (IMV) or noninvasive ventilation (NIV) in early stages should be investigated in larger clinical studies, since oncohematological patients with hypoxemic respiratory failure are the first reason for admission to the PICU, and the decision to choose IMV or NIV as the first respiratory support in early stages can reduce in most cases the lethality in this group of patients. (1) Respiratory support in the form of NIV and humidified oxygen with high-flow nasal cannula (HFNC) are very attractive alternatives in patients with malignant neoplasms. The benefits of NIV in immunocompromised patients in children have been documented. (2) In children, a ventilation strategy incorporating very high levels of carbon dioxide to allow low tidal volumes and limited inspiratory pressures is feasible. This strategy could increase survival in immunocompromised children with severe ARDS, although there are no guidelines on how to ventilate this group of critically ill oncohematologic patients, so individualization of these patients is of fundamental consideration. Guidelines of the Second Pediatric Acute Lung Injury Consensus Conference (PALICC-2) lacks of recomendations for ventilatory management in children with cancer, therefore, the line of research should be focused on this susceptible group. (3) The prognosis of acute respiratory failure (ARF) in immunocompromised children remains guarded, regardless of the initial success or failure of NIV, due to the high rate of recurrent ARF. (4) The application of NIV is feasible and well tolerated in immunocompromised children with ARDS. A brief trial of NIV can be used to test the usefulness of the technique. (5) NIV should be considered a favorable therapeutic approach to avoid endotracheal intubation, as long as children with cancer presenting with acute respiratory distress improve and when clinical and gasometric improvement can be achieved and objectively assessed. In a small report of cases, Ofer Schiller et al. in 12 of 16 BiPAP interventions (75 %; 11 patients), children survived to discharge from the pediatric intensive care unit (PICU) without invasive ventilation. No major complications were observed during bi-level positive pressure ventilation (BiPAP). Thus, two-level positive airway pressure ventilation is well tolerated in pediatric oncology patients presenting with acute respiratory failure and may offer better outcomes sed opportunely and with correct monitoring previously. (6)Another researchion by Piastra et al. noted that children with NIV had a shorter period of hospitalization and PICU. In addition, the success of NIV decreased the number of hours of NIV use as well as the length of stay in the PICU in children with cancer. It appears to be a viable initial option in children with malignancies with acute respiratory failure.The decision to start mechanical ventilation in cancer patients is frequently questioned, because respiratory failure could be a terminal manifestation of their disease. Something that is very controversial when there is lung or airway collapse due to the presence of tumor, space occupying masses in the thoracic cavity (typical of teratoma and ganglioneuroma) or due to the presence of partial or complete obstruction of the upper airway (nasal fibroma, hemangioma, fibromatosis or adenopathy in case of ALL or lymphoma), is to decide whether to start chemotherapy first to debulk the tumor and avoid orotracheal intubation or secure the airway initially, due to the restrictive pattern in case of ALL or lymphoma, fibromatosis or adenopathy in case of ALL or lymphoma) or urgent surgery. (7) Children with hematologic malignancies fare worse than children with solid tumors.Historically it was not clear whether the use of IMV as a therapeutic option in oncology patients had a real clinical benefit. The use of IMV in oncology patients with advanced disease raises not only the question of clinical benefit, but also psychosocial issues. When invasive treatments such as IMV fail, the outcome is often one of considerable suffering for both the patient and their families.Indeed, in view of the increased survival of cancer patients and the evolution of intensive care in the last decade, the place of IMV in this context needs to be reconsidered. We agree with recent literature that the idea that patients with metastases are not ideal candidates for intensive and invasive procedures should be revisited. This is particularly true in the context of modern oncology, which incorporates new and revolutionary treatments that have been a true paradigm shift in the overall survival and quality of life of many cancer patients. However, most of the available studies on noninvasive ventilation have been conducted in high-income countries, which do not match low- and middle-income countries (LMIC) in terms of resource availability, staffing and disease characteristics. Therefore, the disease profile, severity at the time of hospital arrival, vailability of age-appropriate equipment, competence of healthcare professionals to treat patients with noninvasive ventilation, and cost-benefit ratio need to be taken into account.A recent prospective study indicated that mortality rates may be reduced in pediatric NIV patients. Relative to others, the mortality rate (93.33%) was high among patients with hemodynamic instability in this group in whom NIV failed. (8) Pancera et al. reported that most patients with impaired hemodynamic status failed NIV. (9) There are currently no comparative studies of the superiority of high-flow nasal cannula in children with cancer versus noninvasive ventilation. (Figure 1) Research by Garcia et al, in their study of 88 pediatric oncohematologic patients, reported that the first respiratory support on admission to the PICU was, in decreasing order of frequency, high-flow nasal oxygen cannula (HFNC; 50/88), noninvasive ventilation (NIV; 13/88) and nasal oxygen cannula (16/88). MV was required in 47/88 episodes, 38/47 after other respiratory support. In 18/28 children with initial NIV, MV was subsequently required. (10)The usefulness of HFNC or early NIV in children with cancer needs to be investigated in larger clinical studies.We conclude that the use of NIV with good age-appropriate pediatric interface and/or HFNC should be implemented in our pediatric oncologic intensive care units as first-line treatment in children with malignancies who develop acute respiratory failure, except in those with severe hemodynamic status.

In the face of a looming ecological crisis, effective and efficient biomonitoring methods will be critical to the conservation of marine environments. Environmental DNA (eDNA) is now established for detecting species presence within ecosystems and is increasingly being recognised as a tool for marine management. However, concerns surrounding reproducibility and standardisation has led to a lack of confidence and uptake by some end-users as the method transitions from the research domain into biomonitoring practice. Here we incorporate DADA2 into our automatable, containerised, and fully reproducible amplicon (metabarcoding) workflow and highlight how changing analytical steps and parameters may impact inferences from eDNA-derived biodiversity data. By pooling all samples for amplicon sequence variant (ASV) inference, compared to the DADA2 default of independent sample inference, we were able to recover significantly higher ASV counts per sample and directly increased detection of ASVs across replicates and sites. This led to a higher number of species detections and revealed known species as ecological drivers only when ASV inference was pooled across samples. Although, for the purpose of this study, we have focused on the manipulation of a single parameter for a single analytical tool, our findings reiterate the importance of ensuring both are selected in a manner appropriate to the research questions being addressed, and that suitability for comparisons to previously generated datasets is considered. Finally, we provide guidance for robust data processing with the aim to make eDNA more effective, transparent, and useful for management.

In order to improve the control accuracy of vehicle electronic stability program, an Optimal Extended Kalman Filter (OEKF) algorithm is designed based on Extended Kalman Filter (EKF) and optimal control theory. The 7-DOF vehicle model, the linear two-degree-of-freedom vehicle model and the LQG control model of the body electronic stability program (ESP) are built by MATLAB/Simulink. Taking the vehicle sideslip angle and yaw rate as control variables, the OEKF sideslip angle observer is established and simulated in MATLAB/Simulink environment. By comparing with the traditional EKF sideslip angle observer, it is concluded that the OEKF sideslip angle observer can not only estimate the sideslip angle accurately and in real time, but also effectively reduce the lateral acceleration of the vehicle during sideslip and improve the handling stability of the vehicle in driving state. Finally, the effectiveness of the algorithm is further verified by real vehicle road test. In this paper, the algorithm is innovated, and the EKF algorithm and the optimal control theory are combined to study the vehicle sideslip angle estimation and stability control.
