In the pursuit of reducing fuel consumption and emissions, engine downsizing has become a prevalent strategy in the automotive industry. This approach leads to increased mechanical loads on critical components such as the crankshaft. Surface treatments like deep rolling have been used to increase fatigue resistance. This study addresses the establishment of a connection between compressive residual stress induced by deep rolling and the fatigue performance of crankshafts. The experimental setup involves a residual stress measurements using x-ray diffraction and fatigue tests using a crankshaft test rig. Experimental outcomes include residual stress measurements, fatigue tests and correlation with a computational model of the deep rolling process. These results contribute to a deeper understanding of the relationship between residual stress, surface treatments, and fatigue strength in automotive crankshafts, paving the way for future advances in engine design and manufacturing.

CD8+ T cells recognising their cognate antigen are typically recruited as a polyclonal population consisting of multiple clonotypes with varying T-cell receptor (TCR) affinity to the target peptide-MHC (pMHC) complex. Advances in single-cell sequencing have increased accessibility towards identifying TCRs with matched antigens. Here we present the discovery of a monoclonal CD8+ T cell population with specificity for a hepatitis C virus (HCV)-derived HLA class I epitope (HLA-B*07:02 GPRLGVRAT) which was isolated directly ex vivo from an individual with an episode of acutely resolved HCV infection. This population was absent prior to infection and underwent expansion and stable maintenance for at least two years after infection as measured by HLA-multimer staining. Furthermore, the monoclonal clonotype was characterised by an unusually long dissociation time (half-life = 794 seconds and koff = 5.73×10-4) for its target antigen when compared to previously published results. A comparison with related populations of HCV-specific populations derived from the same individual and a second individual suggest that high-affinity TCR-pMHC interactions may be inherent to epitope identity and shape the phenotype of responses which has implications for rational TCR selection and design in the age of personalised immunotherapies.

Type I hypersensitivity, also known as classical allergy, is mediated via allergen-specific IgE antibodies bound to type I FcR (FcεRI) on the surface of mast cells and basophils upon cross-linking by allergens. This IgE-mediated cellular activation may be blocked by allergen-specific IgG through multiple mechanisms, including direct neutralization of the allergen or engagement of the inhibitory receptor FcγRIIb which blocks IgE signal transduction. In addition, co-engagement of FcεRI and FcγRIIb by IgE-IgG-allergen immune-complexes causes down-regulation of receptor bound IgE, resulting in desensitization of the cells. Both, activation of FcεRI by allergen-specific IgE and engagement of FcγRIIb by allergen-specific IgG are driven by allergen-binding. Here we delineate the distinct roles of antibody affinity versus avidity in driving these processes and discuss the role of IgG subclasses in inhibiting basophil and mast cell activation.

Mean stress effect remains as a critical aspect in multiaxial fatigue analysis. This work presents a new criterion which, based on classical Findley criterion, applies a material-dependent exponent to the mean normal stress term and includes the ultimate tensile stress as a fitting parameter. The criterion has been checked against an extended version of the Papuga database of multiaxial experimental tests with 485 results, and compared with the criteria by Findley, Robert and Papuga. The new criterion provides outstanding results for pure uniaxial cases, with multiaxial performance similar to Robert criterion with a smaller range of error and a conservative trend. These features enhance the applicability and versatility of the criterion for its use in fatigue design of structural components.

In the internal combustion engine, combustion characteristics were important from the point of the overall performance of the engine. Current paper investigates the influence of injection system parameters such as injection pressure (400,500 and 600 bar), start of pilot injection timing (35°, 40° and 45° CA bTDC), start of main injection timing (10°, 15° and 25° CA bTDC) and a quantity of percentage fuel injection (10:90, 20:80 and 30:70 in percentage) and their values on combustion characteristics of the small single-cylinder CRDI diesel engine. Combustion characteristics such as in-cylinder pressure, heat release rate, rate of pressure rise and mean gas temperature were considered. The effect of injection system parameters were discussed in details with the help of a graphs, plotted with respect to crank angle. It was observed that the taken injection system parameters improve the combustion characteristics of the engine, when compared to the conventional mechanical fuel injection system. By optimising these injection system parameters from performance and emission point of view definitely gives a large improvement in the overall performance of the engine.

Although certain group of patients can benefit from cardiac resynchronization therapy, many patients do not fulfil criteria for such treatment. Cardiac contractility modulation (CCM) could be an option for them. CCM, by delivering of non-excitable impulses can improve cardiac contractility with concomitant HF symptoms reduction. In presented case, patient benefited from

In this paper, we propose and implement an in situ direct reduction reaction of K2PtCl6 precursor under mild reaction conditions using topotaxial reaction and the reducbility of graphene oxide. The reduced product platinum atom clusters are intercalated onto the GO surface, resulting in platinum nanocatalyst. The structure, content, and morphology of Pt/GO composites are studied using X-ray dif-fraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS), among other methods. It has been demonstrated that Pt4+ ions in the K2PtCl6 precursor are reduced to Pt0 atoms under moderate reaction conditions, which are equally distributed across the GO surface in the form of atom clusters with an average particle size of 10 nm. The platinum nanocluster has a conventional face-centered cubic crystal structure, with Pt crystal planes (111), (200), (220), and (311) etc.

The study addresses the necessity for precise path loss prediction in wireless communication design, advocating for data-driven methodologies over conventional models, particularly in the context of dynamic signal variations in advanced 5G technologies. Employing a robust data-driven model based on neural network architecture, the research explores vital parameters to train a multi-layered neural network. Correlation analyses highlight significant associations, emphasizing the impact of environmental conditions and path characteristics on path loss. The proposed model, trained over 150 epochs with three layers, demonstrates superior performance in Mean Absolute Error, Mean Squared Error, and Root Mean Squared Error compared to traditional models. Specifically, it outperforms Okumura-Hata, Costa 231, and Egli models with notable accuracy metrics. Leveraging TensorFlow and Python, the study advances our understanding of parameter-path loss relationships in 5G wireless communication, offering insights for optimized network design and resource allocation. The research pioneers a simulation-based approach using neural networks for path loss prediction, showcasing heightened accuracy and reduced estimation errors. Future directions include exploring advanced machine learning algorithms and assessing the influence of technologies like 5G on path loss prediction.

In this paper, a class of preinvex vector interval optimization problems (VIOP) with gH-subdifferential is considered, and the optimality conditions and dual results are gained. Firstly, the definition of subgradient for preinvex interval valued function under gH-difference is given, and examples are given to verify the difference between the subgradient in this paper and the subgradient in[28]. Secondly, by means of gH-subdifferential, the Karush-Kuhn-Tucker sufficient and necessary conditions for preinvex (VIOP) are studied. Then, the Mond-Weir dual problem and Wolfe dual problem of preinvex (VIOP) are established, furthermore, weak duality, strong duality, and converse duality theorems are obtained by using the gH-subdifferential. Some examples are given to illustrate the main results. To some extent, the main results generalize the existing relevant results.

Oxygen migration in solid oxides affects material properties; however, a rigorous conceptual framework to quantify this dynamic process has been lacking. Herein, a dynamic oxygen migration-release model was developed using the differential element approach. This model revealed that the oxygen release rate of metal oxides decreases exponentially with the amount of released oxygen. And the migration processes of bulk oxygen and surface oxygen reactions were differentiated, and the energy barriers were determined. CeO 2 with various morphologies was used as a case study, showing differences in energy barriers between crystal facets. The adaptability of such an oxygen migration-release model can be expanded to other metal oxides, like ceria-zirconia solid solution, manganese oxide and iron oxide, increasing its potential universality. The oxygen migration-release law that has been found provides a theoretical foundation for the optimization methods of functional metal oxide materials, facilitating the assessment of oxygen reactivity within metal oxides.

Abstract Introduction: Upper abdominal metastases of bladder cancer are very rare. This case report describes the first ever patient with bladder cancer progression initially presenting with gastric outlet obstruction due to peritoneal carcinomatosis of upper gastrointestinal system. Case report: We present the case of a 78-years-old male patient with diagnosed high risk NMIBC (high grade pT1 + CIS) who was admitted to hospital with vomiting. At the time, patient was between 2. and 3. BCG instillation cycle, following two transurethral resections. Routine urological follow-up one month before admission showed no signs of tumour. Gastroscopy revealed duodenal stenosis without intraluminal lesions. First CT- scans showed inflammation of the fat tissue surrounding duodenum without clear signs of metastases. Laparoscopic exploration described lesions typical for peritoneal carcinomatosis. Pathohistological analysis of taken samples proved urothelial cancer cells, confirming the diagnosis of metastatic bladder cancer. Conclusion: This case report presented an unusual presentation of bladder cancer that could help clinicians in everyday practice, as it might bring focus to a progression potential of the bladder cancer, eventually encouraging improvement in diagnostics and therapy. Keywords: non-muscle invasive bladder cancer, NMIBC, metastatic bladder cancer, peritoneal carcinomatosis, gastric outlet obstruction

Eosinophilic solid and cystic renal cell carcinoma (ESC RCC) is a relatively rare kidney tumor subtype, first documented pathologically by Trpkov et al. in 2016[[1]](#ref-0001).Although first described and named in pathology literature, ESC RCC is not included in the 2016 World Health Organization (WHO) classification. However, the Genitourinary Pathology Society recommended it in 2021 as a new renal cell carcinoma entity[[2]](#ref-0002).Owing to its low incidence and relative rarity, as well as a general lack of familiarity among pathologists, ESC RCC can easily be confused with other renal tumors bearing similar morphological characteristics.In this article, we will summarize and analyze clinicopathology, clinical manifestations, imaging, and differential diagnosis of ESC RCC. We will draw insights from a recently diagnosed ESC RCC patient at our hospital and study relevant literature from both domestic and international sources. Our goal is to enhance the diagnosis and comprehension of ESC RCC among medical professionals and provide a deeper understanding of this rare subtype.

Intracellular plant defense against pathogens is mediated by a class of disease resistance genes known as NB-LRRs or NLRs (R genes). Many of the diseases these genes protect against are more prevalent in regions of higher rainfall, which provide better growth conditions for the pathogens. As such, we expect a higher selective pressure for the maintenance and proliferation of R genes in plants adapted to wetter conditions. In this study, we enriched libraries for R genes using RenSeq from baits primarily developed from the common sunflower (Helianthus annuus) reference genome. We sequenced the R gene libraries of Silphium integrifolium Michx, a perennial relative of sunflower, from 12 prairie remnants across a rainfall gradient in the Central Plains of the United States, with both Illumina short-read (n=99) and PacBio long-read (n=10) approaches. We found a positive relationship between the mean effective annual precipitation of a plant’s source prairie remnant and the number of R genes in its genome, consistent with intensity of plant pathogen coevolution increasing with precipitation. We show that RenSeq can be applied to the study of ecological hypotheses in non-model relatives of model organisms.

Background Laser excision is used routinely in the treatment of sarcoids but may be ineffective in cases where complete excision cannot be achieved. A multimodal approach is warranted in these cases. 5-FU may improve the lethal effect of cryotherapy as an adjunct to laser excision. Objectives To compare two treatment protocols for equine sarcoids: laser excision alone versus a combination protocol of laser excision, cryotherapy, and 5-FU chemotherapy. Factors associated with sarcoid recurrence are also investigated. Study Design Retrospective case controlled study. Results Eighty-four horses with 168 histologically confirmed sarcoids were included, with a median follow up time of 39 months (IQR 21-62 months). Sarcoid recurrence at the treated site was reported in 38% of cases and in 23% of any individual sarcoids. No significant difference was demonstrated between treatment categories in either rate of sarcoid recurrence (p=0.45 for any treated horse, p=0.63 for individual sarcoids) or time to sarcoid recurrence (p=0.73). Sarcoid recurrence was higher in horses with a greater number of sarcoids (OR 1.2 (1.0-1.5), p=0.03); when treatment had been received prior to admission (OR 7.6 (2.0-33), p=0.004); for individual sarcoids ≥100mm in diameter (OR 5.6 (1.1-30), p=0.03); and for treatment under general anaesthesia (OR 5.0 (1.4-19), p=0.01). Horses with urogenital sarcoids and >1 mixed sarcoid experienced more rapid recurrence (HR 3.6 (1.3-10), p=0.02 and HR 9.9 (3.3-30), p<0.001) and recurrence was less rapid following the treatment of a horse’s first sarcoid (HR 0.3 (0.1-0.7), p=0.009). Main Limitations Significant differences in case populations in each treatment category. Treatment selection was neither blinded nor randomised and missing data and recall bias limit the study’s power. Sarcoid recurrence was owner reported. Conclusions When assessing the likelihood of sarcoid recurrence, characteristics of the individual patient and sarcoid(s) are likely to be more significant than selection of any individual treatment protocol.

The Cordillera Central is a vast mountain range, spanning 22,500 km2 in the Philippines, containing some of the country’s last remaining intact forests. These forests are a reservoir for biodiversity and home to many poorly-known species, including those in the genus Rafflesia, renowned for containing the world’s largest flowers. Here we describe Rafflesia balatociana, a distinctive yet overlooked taxon from the high elevation moss forest, which we name after the Balatoc Indigenous Peoples, one of the subtribes in the Kalinga Province. This species is distinguished from its close relatives by a combination of conspicuous and stable characters including a double-dentate disk rim and strap-shaped lacuna on the annulus interior. We compare R. balatociana with co-occurring species in the Cordillera Central, provide a key, and consider our findings in the wider context of the exceptional biodiversity of this region and its conservation requirements. We propose R. balatociana should be classified as Critically Endangered, and recommend its habitat be declared as either a Critical Habitat Area (CHA) or a Local Conservation Area (LCA).

Emotional contagion refers to the tendency for individuals to replicate the emotional states of others primarily within the context of social interactions. Prior research has focused on real-time emotional contagion during interpersonal communication. However, this study proposed that social interaction experiences might also play a role in promoting emotional contagion. To investigate this issue, the present study divided participants into the interactive group and the control group and conducted EEG-based hyperscanning to investigate the impact of interpersonal interaction experience on emotional contagion. Behavioral results indicated that individuals reported a greater psychological closeness to their partners after experiencing interaction. Additionally, the interactive group showed stronger emotional congruence between observers and senders. EEG results further demonstrated that inter-brain synchrony in the emotional contagion phase among the observer and sender of the interactive group was significantly higher than that of the control group, particularly in the negative emotions. This research suggests that social interaction experience may affect emotional contagion by altering the interpersonal states. It also adds to our understanding of how social interactions can shape our emotional experiences and emphasizes that interpersonal experiences might be a key factor in promoting emotional contagion.

Amphibians are among the most threatened vertebrate taxa globally. Their global decline necessitates effective conservation actions to bolster populations across both the larval and adult life stages. Constructing man-made ponds is one such action proven to enhance reproduction in pond-breeding amphibians. However, to achieve successful conservation outcomes, extensive prior knowledge about the ecology and behaviour of the target species is required. In this study, we investigated how different hydroperiod regimes impact the growth and development of Litoria littlejohni tadpoles. Over a 28-week period, tadpoles were exposed to three hydroperiod treatments: Constant High, Declining, and Constant Low water levels. Weekly measurements of snout-to-vent length, body mass, and Gosner stage were taken to assess any treatment-related changes. To determine whether different treatments affected locomotor performance, a jump test was conducted three weeks post metamorphosis. Individuals did not exhibit developmental plasticity in response to declining water, with a mean time to metamorphosis of 93.3 days. Comparatively, when L. littlejohni tadpoles were exposed to low water volumes, they were able to speed up development and reduce time to metamorphosis, with a mean time of 56.5 days. The speeding up of development had an apparent consequence for L. littlejohni. We found support for trade-offs between rapid development and reduced morphometric measurements post-metamorphosis which resulted in reduced locomotive ability. Individuals from Constant Low water treatments exhibited an average total jumping distance of 170.5 cm over 10 consecutive jumps, compared to 235.8 cm in Constant High and 209.5 cm in Declining treatments. Rapid larval development aids tadpoles in escaping suboptimal aquatic conditions, but its effects on locomotion may impact foraging efficiency and predator escape ability. Understanding developmental plasticity in threatened amphibians, especially in response to hydroperiod variations, is crucial for conservation programs, particularly under future climate change scenarios predicting increased drought and reduced hydroperiods in aquatic environments.

Purpose The generation of representative disease phenotypes is important for ensuring the reliability of the findings of observational studies. The aim of this manuscript is to outline a reproducible framework for reliable and traceable phenotype generation based on real world data for use in the Data Analysis and Real-World Interrogation Network (DARWIN EU®). We illustrate the use of this framework by generating phenotypes for two complex diseases: pancreatic cancer and systemic lupus erythematosus (SLE). Methods The phenotyping process involves a 14-step process based on a standard operating procedure co-created by the DARWIN EU® Coordination Centre in collaboration with the European Medicines Agency. A number of bespoke R packages were utilised to generate and review codelists for two phenotypes based on real world data mapped to the OMOP Common Data Model. Results Phenotypes were generated for both pancreatic cancer and SLE, and cohorts were generated using the Clinical Practice Research Datalink (UK primary care records) and Pharmetrics (US health claims data). Diagnostic checks were performed, which showed these cohorts had broadly similar incidence and prevalence figures to previously published literature. Additionally, co-occurrent symptoms, conditions, and medication use were in keeping with pre-specified clinical descriptions based on previous knowledge. Conclusions Our detailed phenotyping process makes use of bespoke tools and allows for comprehensive codelist generation and review, as well as large-scale exploration of the characteristics of the generated cohorts. Wider use of structured phenotyping methods will be important in ensuring the reliability of observational studies for regulatory purposes.

Harmonic pollution has a major detrimental effect on the power quality of low voltage distribution networks as a result of the proliferation of non-linear loads. The filter injects compensating current equal to the harmonic current needed by non-linear loads at the point of common coupling. Progressive harmonic compensation can be achieved by using shunt active filters at the metering point of each non-linear consumer. This paper proposes a modification in the control scheme of filter based on resistive load synthesis approach. The analysis of the proposed method is carried out in MATLAB Simulink. The control algorithm is used to calculate the filter current by identifying the harmonic current contribution of source at each consumer location. The efficiency of the suggested method in enhancing power quality of system is validated by real time simulation using OPAL-RT.

Although virtual sandboxes are an essential component of platforms such as smart cities and smart parks, the efficiency of visual rendering and Web access is frequently hampered by many scenarios and models. This paper combines the polygon reduction algorithm with human visual system characteristics, proposes a real-time adjustment method for model data for virtual scenes, determines the degree of surface reduction based on the distance of the model’s center point in real-time observation, and then adjusts the number of triangular faces of the model in the scene using the collapse principle, to dynamically adjust the data amount of the model. It also uses coroutines to realize the parallel surface reduction of multiple objects and improve the rendering efficiency further. Experiments show that the optimized algorithm does not affect the visual observation effect after reducing the visual distance and storage space by 12%, indicating that it is a highly adaptive virtual scene data optimization method.
