Background: Solid pseudopapillary neoplasm of the pancreas (SPN) in children is rare tumor with low malignant potential. Some tumors however behave aggressively. There is very little literature on the management of these variants especially in children. We share our experience of managing large and recurrent SPN and explore the clinicopathological findings correlating to the risk of recurrence. Methods: This is a retrospective study of children who were treated for SPN between 2012 and 2022 at a tertiary care center in India. The clinicopathological features and management strategies in these children were evaluated. Results: 16 children with SPN were treated during this period (88% girls). The median age of presentation was 12 years (IQR 9-14). All children presented with abdominal pain. Computed tomography gave a definitive diagnosis in 81% of cases. The tumor predominantly involved the head of the pancreas (n=9, 56%). Eight of nine children classified as high-grade malignant had a benign course. One child had a recurrence of the tumor 4 years after the initial resection and further recurrence on chemotherapy. She required radiation therapy in addition to reoperation following which she is disease free for 77 months. The overall median follow-up was 46 months (IQR 18-72 months). Conclusion: Complete resection of the tumor provides a cure in most patients with SPN. Recurrent tumors require a multi-modality approach. Long-term survival is good. Better prognostic criteria with immunohistochemistry are required to predict the behavior of these tumors as the WHO criteria for malignancy correlate poorly with clinical outcomes in childhood SPN.

Cellular networks are projected to deal with an immense rise in data traffic, as well as an enormous and diverse device, plus advanced use cases, in the nearest future; hence, future 5G networks are being developed to consist of not only 5G but also different RATs integrated. In addition to 5G, the user’s device (UD) will be able to connect to the network via LTE, WiMAX, WiFi, Satellite, and other technologies. On the other hand, Satellite has been suggested as a preferred network to support 5G use cases. However, achieving load balancing is essential to guarantee an equal amount of traffic distributed between different RATs in a heterogeneous wireless network; this would enable optimal utilisation of the radio resources and lower the likelihood of call blocking/dropping. This study presented an artificial intelligent-based application in heterogeneous wireless networks and proposed an Enhanced Particles Optimization (EPSO) algorithm to solve the load balancing problem in 5G-Satellite networks. The algorithm uses a call admission control strategy to admit users into the network to ensure that users are evenly distributed on the network. The proposed algorithm was compared with Artificial Bee and Simulated Annealing algorithm using three performance metrics: throughput, call blocking and fairness. Finally, based on the experimental findings, results outcomes were analysed and discussed.

In this letter, the colored point cloud quality assessment in Augmented Reality (AR) environment was fully studied through subjective test. Firstly, we present a point cloud dataset, named Point Cloud Quality Dataset-AR (PCQD-AR), including ten reference point clouds and their 90 distorted versions, which were encoded by the reference software of Video-based Point Cloud Compression (V-PCC) under different pairs of geometry and texture quantization parameters. Then, the impact of geometry and texture distortions on perceived quality of point clouds in the AR environment was discussed in detail. Moreover, we evaluate the performance of existing objective point cloud quality assessment metrics on the proposed dataset. The subjective dataset including the values of Mean Opinion Score (MOS) will be released after acceptance.

[Abstract] Objective To analyze the echocardiographic characteristics and pregnancy outcomes for fetuses with premature complete closure of the fetal ductus arteriosus. Methods A retrospective analysis was performed for 8 cases of premature ductus arteriosus closure diagnosed by prenatal ultrasonography in the Hunan Maternal and Child Health Hospital from July 2019 to August 2022, and the characteristics of fetal echocardiography and pregnancy outcomes of the 8 cases were analyzed and summarized. Results All 8 cases of premature closure of ductus arteriosus were detected in the third trimester. In all cases, the intima of the ductus arteriosus was thickened and occluded, the ductus arteriosus could be seen with slightly hyperecho, and no blood flow signal was found in the ductus arteriosus by Doppler. The right heart was enlarged in 7 cases, and the whole heart was enlarged in 1 case. Tricuspid valve regurgitation was observed to different degrees, of which 7 cases were severe and 1 case was moderate. The pulmonary arteries of 8 patients had varying degrees of widening. Three of the 8 fetuses had a small amount of pericardial effusion. All 8 cases were delivered by cesarean section, and one newborn died after follow-up. The prognosis of the other newborns was good. Conclusion The parameters of prenatal echocardiography are helpful for the prognosis of fetuses with premature closure of the ductus arteriosus. Early prenatal detection, close observation and clinical guidance can be used to select the right time of delivery.

Objective: To better understand how to clear cell renal cell cancer (ccRCC) is affected by the regulator of G protein signaling-1 (RGS1), its effect on immune infiltration, macrophage polarization, tumor proliferation migration. Patients and Methods: In this study, a total of 20 surgical specimens of patients with pathological diagnosis of ccRCC were selected for testing, while the expression of RGS1 in tumors, immune infiltration, macrophage polarization, were combined with TGCA database and GO analysis. We also further explored and studied the expression and function of RGS1 in tumor microenvironment(TME), investigated how RGS1 affected tumor growth, migration, apoptosis, and other traits. Results: RGS1 was found to be expressed at higher quantities in ccRCC than in normal cells or tissues. By using the TCGA database and GO analysis to describe the expression of RGS1 in a range of tumors, it was found that ccRCC had a much higher level of RGS1 expression than other tumor types. The results of gene enrichment analysis indicated that overexpression of RGS1 may be associated with immune infiltration. The outcomes of in vitro tests revealed that RGS1 overexpression in ccRCC did not significantly alter the proliferation and migration ability of ccRCC, but RGS1 overexpression promoted apoptosis in ccRCC. By in vitro co-culture experiments, RGS1 overexpression inhibited M2 macrophage polarization and also suppressed the Jagged-1/Notch signaling pathway. Conclusions: RGS1 is highly expressed in ccRCC, while overexpression of RGS1 may increase immune infiltration in the TME and reduce the polarization of M2 macrophages while promoting apoptosis in ccRCC.

With the invention of high-throughput screening technolo- gies, innumerable drug sensitivity data for thousands of can- cer cell lines and hundreds of compounds have been pro- duced. Computational analysis of these data has opened a new horizon in the development of novel anti-cancer drugs. Previous deep-learning approaches to predict drug sensitiv- ity showed drawbacks due to the casual integration of ge- nomic features of cell lines and compound chemical features. This paper proposes a new deep learning model, DRPO, for efficient integration of genomic and compound features in predicting the half maximal inhibitory concentrations (IC50). First, matrix factorization is used to map the drug and cell line into latent ’pharmacogenomic’ space with cell line-specific predicted drug responses. Using these drug responses, we next obtained the essential drugs using a Normalized Dis- counted Cumulative Gain (NDCG) score. Finally, the essen- tial drugs and genomic features are integrated to predict drug sensitivity using a deep model. Experimental results based on RMSE and NDCG scores on CCLE & GDSC1 datasets show that our proposed approach has outperformed the previous approaches, including DeepDSC, CaDRRes, and KMBF. With these good results, it shows great potential to use our new model to discover novel anti-cancer drugs for precision medicine.

An effective and economical acid-promoted three-component reaction for the construction of C-P and C-C bonds for the synthesis of γ-ketone phosphine oxides was developed. Detailed mechanistic experiments confirmed that the reaction proceeds by phospha-aldol-elimination, in which a benzylic carbocation is generated from the phosphorylation of aldehydes, which then reacts with ketone enolates under acidic conditions.

MoSe2 as one graphene-like 2D transition metal selenide has attracted great attention. However, its application for the hydrogen evolution reaction (HER) is still restricted by the poor electrical conductivity and structural restacking. In this work, an excellent electro-catalyst for hydrogen production is developed based on the in-situ synthesis of V-doped MoSe2 confined on carbon black nanoparticles (denoted as V-MoSe2/CB) via a sol-gel process. The characterization results show the carbon black nanoparticles can protect the V-MoSe2 nanosheets from agglomeration, resulting in ultra-thin thickness and short vertical lattice arrays. Meanwhile, Density func-tional theory (DFT) calculations indicate that vanadium doping can optimize the electronic structure of MoSe2. Accordingly, compared to pure MoSe2, V-MoSe2 and MoSe2/CB electrocatalyst, V-MoSe2/CB exhibits improved electrocatalytic activity with a small overpoten-tial of 166 mV at -10 mA cm-2 and a small Tafel slope of 65 mV dec-1. This work paves a new way for improving the HER performance through synergistic morphology, structure and electronic regulation.

Although the amount of acidic deposition has recently decreased in Japan, acid deposition has deteriorated some forest ecosystems during the past few decades. We investigated the yearly variations in stream water chemistry for more than 20 years in two areas (Yusuhara and Taisho) in the Shmanto River Basin, southern Japan, where the effects of acidic deposition are considered to be modest. Stream water samples were collected monthly from three forest watersheds selected at each site. The annual means of the stream chemistry were predicted by multiple regression analysis. The sunlight hours were positively related with the potassium, magnesium, calcium, nitrate, sulfate, and bicarbonate concentrations in stream water. The results suggest that long sunlight hours boost the photosynthetic activities, thus promoting soil respiration and decomposition of soil organic matter; moreover, a higher carbonic acid concentration in the soil solution promotes cation weathering and carbonic acid dissociation to bicarbonate. The ammonium, nitrate, and sulfate concentrations in the bulk precipitation have decreased at Yusuhara and the sodium, magnesium, calcium, chloride, nitrate, and sulfate concentrations in the stream water have decreased in both areas. The nitrate and sulfate concentrations apparently responded to the decreasing input of acidic deposition. Given the decreasing trends in magnesium and calcium concentration with no change in bicarbonate concentration, we inferred that previous inputs of acidic deposition enhanced the rate of rock weathering.

The electrochemical and charge storage performance of a fluorine-free structurally flexible pyrrolidinium-based ionic liquid hybrid electrolyte (HILE) in a symmetric graphite-based supercapacitor is thoroughly investigated. The HILE revealed thermal decomposition at 270 ºC, a glass transition (T g) temperature of −73 ºC, and ionic conductivity of 0.16 mS cm −1 at 30 ºC. A systematic variable temperature 1H and 31P NMR spectroscopy and diffusometry, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charge-discharge (GCD) are employed. HILE-based supercapacitor demonstrated a notable specific capacitance of 186 Fg −1 at a scan rate of 1 mVs −1 and a specific capacitance of 122 Fg −1 at a current density of 0.5 Ag −1. The maximum energy density of 49 Wh kg −1, a power density of 370 W kg −1 at a current density of 0.5 A g −1 and a potential window of 4V were obtained. HILE displayed a promising electrochemical performance over a wide potential window of 4V and temperature range (−20 ºC to 90 ºC) in a symmetric graphite supercapacitor.

The thermal anomaly area of electrical equipment in the substation is often hidden due to its small thermal area and multiple anomalies overlaid. Accurately identify the thermal area is demanded on the condition detection of electrical equipment, where the anomaly points of electrical equipment in infrared images are generally small and of low resolution. We propose an improved YOLOv4 algorithm for infrared image anomaly area identification, which can detect the thermal generation phenomenon of electrical equipment. We add a new target detection branch to the shallow feature map of 104×104, which can better extract small target semantic information. The training process is enhanced with cosine annealing and mosaic data enhancement. We establish a total of 719 infrared images of five types of thermal anomalies electrical equipment to test our network. The accuracy of our model reach to as high as 96.78%, with a detection speed of 17 f/s and an AP@0.5 of 94.23%. Compared with SSD, YOLOv4 and Faster RCNN, the algorithm in this paper obtains the highest AP@0.5 with 94.23%, which is the best performance compared with the original YOLOv4 model in accuracy. The model is robust to noise and luminance disturbances, and still provides good recognition under disturbances.

Faced with the uncertainty of wind and photovoltaic power output and load fluctuation caused by the increase of new energy penetration in active distribution network, the demand for operational flexibility and the construction demand for flexible resources of distribution network are gradually increasing. The flexible operation of active distribution network can be realized by coordinated planning of the soft open point integrated with energy storage system (ESOP) and flexible resources. Firstly, the flexibility resource adjustability evaluation and margin indicators are proposed for the response model of typical flexibility resources. Secondly, a two-stage distributionally robust coordinated planning model considering the coordination planning scheme of distributed generation, flexibility resource and ESOP as well as the comprehensive norm uncertainty of wind power and photovoltaic outputs multi-operation scenarios is established with the distribution network construction cost, annual operation cost and annual power sales revenue as the objective functions meanwhile the investment and flexibility resource operation as constraints. Finally, the column constraint generation algorithm is used to solve the problem, and the effectiveness of the proposed model is verified by the modified IEEE33 node system.

In this paper, a new approach is proposed for the optimal operation of the strategic microgrids in the day-ahead market in the presence of rivals. The method describes a bi-level multi-objective operation of price maker participants (microgrids) that are going to maximize their profit in the presence of rivals and minimize their emissions. The upper-level problem in a bi-level mathematical optimization problem with equilibrium constraints (MPEC) seeks to maximize the profit of price maker participants, and the lower level maximizes the social welfare. Karush-Kuhn-Tucker (KKT) conditions and duality theory are utilized to convert the bi-level model to a mixed-integer linear programming model. The Epsilon constraint method is used to solve the bi-level-multi-objective problem in order to maximize the profit of the linearized model and reduce the emissions of price maker participants. The method generates some Pareto optimal solutions, and the fuzzy decision-making method is used to find the best solution among Pareto optimal solutions. To show the effect of the network on the studies, the power transmission distribution factor (PTDF) method has been used. The proposed method is tested on a 6-bus system in various scenarios. The results show the good performance of the proposed method.

Prosecutors are the key decision-makers when it comes to plea bargaining (Ball, 2006; Davis, 2001), which is responsible for the resolution of about 90% of criminal cases (Johnson, 2023). We distributed a mixed-method survey to a national sample of 180 prosecutors to ask them their key considerations when they initiate and prosecute a criminal case. Additionally, our survey asked prosecutors to provide any additional information they wanted to share regarding plea bargaining. We then conducted a qualitative content analysis, informed by Schreier (2012), to comprehensively identify the factors the prosecutors discussed. We found several factors that prosecutors take into consideration when starting to evaluate a criminal case: qualities of the criminal defendant (e.g., criminal history), victim input (e.g., victim wishes), and factors specific to the case (e.g., evidence strength). Additionally, when asked if they would like to share anything regarding plea bargaining, some prosecutors stressed the necessity of the plea system, some shared their punishment orientations, and others discussed how they determine punishment on a case-by-case basis. Overall, prosecutors tended to stress criminal history as largely influential in their plea decision-making. This study provides insight into prosecutorial plea bargain decision-making while providing opportunity for future research.

Wind farm control can play a key role in reducing the negative impact of wakes on wind turbine power production. The helix approach is a recent innovation in the field of wind farm control, which employs individual blade pitch control to induce a helical velocity profile in a wind turbine wake. This forced meandering of the wake has turned out to be very effective for the recovery of the wake, increasing the power output of downstream turbines by a significant amount. This paper presents a wind tunnel study with two scaled wind turbine models, of which the upstream turbine is operated with the helix approach. We used tomographic particle image velocimetry to study the dynamic behavior of the wake under influence of the helix excitation. The measured flow fields confirm the wake recovery capabilities of the helix approach compared to normal operation. Additional emphasis is put on the effect of the helix approach on the breakdown of blade tip vortices, a process that plays an important role in re-energizing the wake. Measurements indicate that the breakdown of tip vortices, and the resulting destabilization of the wake is enhanced significantly with the helix approach. Finally, turbine measurements show that the helix approach was able to increase the combined power for this particular two turbine setup by as much as 15%.

This paper transforms the Turing machine into von Neumann’s modern code paradigm. Values are unordered identifiers. The operations assign-value and equals-value are computer hardware instructions. Its programs have dual numeric and natural language representations. The same representation supports a thesaurus of quotations that capture ideas. Appendices provide a program for the universal Turing machine, a specification of numeric identifiers from 2 bytes to 80 bytes, and a specification of 64-bit disk block identifiers from 64 bytes to 64 megabytes. Numeric identifiers may include a timestamp and SHA-1 revision. Disk blocks are self-identifying. Aims and Scope This paper is a research article that presents a new foundation for computer software. The definition of memory machine is complete. The implementation of memory machines (Avev and Thesa) is a work in progress. Thesa (silent ‘h’) contains quotations relevant to Avev and Thesa development. For example, Thesa includes many references from Software: Practice and Experience. Avev is currently a primitive language. It will eventually include the features of programming languages. The Echonet prototype for Avev is a demonstration of what can be done. The readership is anyone interested in new approaches to computer programming. The Byte article on Echonet was well received.

Background: Older adults often have polypharmacy and multiple comorbidities. Cardiovascular diseases (CVDs) are the most common morbidities in older adults and are linked to many adverse drug effects and drug-related issues. Several patient settings use the medication appropriateness index (MAI) to assess older adults’ Potentially Inappropriate Medication (PIM) prescribing. Aim: This study estimated CVDs outpatient clinic PIM prescribing. It also tested the MAI’s ability to detect and quantify PIMs in CVD outpatient clinics. Methods: It is a cross-sectional, single-center, cardiovascular outpatient clinic study. Demographic, medical, and drug data from 65 years or older patients were retrospectively reviewed. Two clinical pharmacists randomly selected 70 patients and assessed medication appropriateness using the MAI. Statistical Package for the Social Sciences (SPSS) descriptive and logistic regression analyses calculated the number of potentially inappropriate medications, the percentage of patients with inappropriate medication prescribing, and factors associated with inappropriate medication prescribing. Results: Total of 87.14% of participants had PIMs. Two clinical pharmacists evaluated 539 prescriptions, and 59.9% had an MAI weighted score of zero (no prescription error). Drug-drug interaction, duplication, and drug-disease interaction almost perfectly agreed among raters. The two raters’ MAI criteria kappa coefficient was 0.44, indicating moderate agreement. The results showed that only some medications significantly affected MAI-defined inappropriate prescribing. Conclusion: The MAI is a reliable and valid tool in CVD outpatient clinics. A relatively high prevalence of PIMs was found in the studied population. It mandates implementing specific measures to reduce PIMs.

The concept of innovation has increased importance in the industrial environment to maintain a competitive advantage in the global market. Thousand innovation projects are proposed daily to create or rethink new or existing products. All this change directly impacts the whole manufacturing system, supply chain, and deliverables. The decision-making process to choose which innovation project will bring better benefits or opportunities follows the criteria of the company’s managers. However, the criteria are subjective or without relevant information for a bold decision, leading to a wrong decision. Based on this context, this research proposed a Fuzzy-QFD approach to assess and prioritise innovation projects based on 40 criteria divided by faces of innovation (desirability, technical feasibility, and economic feasibility) and maturity levels (ideation, preparation, validation, incubation). This approach was tested in two innovation projects in the metal-mechanical industry to determine the priority between of them. As a result, Project 01 has a higher maturity level than Project 02, proving the benefit of the proposed approach to support the decision-making process in a Metal-Mechanical industry.

Differences in attentional orienting and regulation of arousal are frequently comorbid traits in many clinical populations including those with autism. The Arousal Biased Competition theory has shown that arousal strengthens pre-existing biases for the perception and memory of objects and may also influence the effectiveness of attentional orienting systems more generally. In order to investigate this possibility, 38 typically developing participants completed both pro- and antisaccade gap-overlap paradigms at multiple levels of autonomic arousal induced by varying levels of background noise and recorded using skin conduction level (SCL). Participants also completed the Autism Spectrum Quotient (AQ) and were assigned to either a high or low AQ group. Linear mixed effects modeling analysis showed several significant interactions between SCL and AQ with Task (prosaccade vs. antisaccade) and Trial Type (gap vs. overlap). We interpret these results as suggesting that arousal improves the effectiveness of top-down (endogenous) attentional mechanisms but notably this impact was weaker for individuals in the high AQ group. Thus, while arousal appears to play an important role in upregulating top-down control, this influence may be altered in autism.

TYK2 is a non-receptor tyrosine kinase, member of the Janus kinases (JAK), with a central role in several diseases, including cancer. The JAKs’ catalytic domains (KD) are highly conserved, yet the isolated TYK2-KD exhibits unique specificities. In a previous work, using molecular dynamics (MD) simulations of a catalytically-impaired TYK2-KD variant (P1104A) we found that this amino-acid change of its JAK-characteristic insert (αFG), acts at the dynamics level. Given that structural dynamics is key to allosteric activation of protein kinases, in this study we applied a long-scale MD simulation and investigated an active TYK2-KD form in the presence of adenosine 5’-triphosphate and one magnesium ion that represents a dynamic and crucial step of the catalytic cycle, in other protein kinases. Community analysis of the MD trajectory shed light, for the first time, on the dynamic profile and dynamics-driven allosteric communications within the TYK2-KD during activation and revealed that αFG and amino-acids P1104, P1105 and I1112 in particular, hold a pivotal role and act synergistically with a dynamically coupled communication network of amino-acids serving intra-KD signaling for allosteric regulation of TYK2 activity. Corroborating our findings, most of the identified amino-acids are associated with cancer-related missense/splice-site mutations of the Tyk2 gene. We propose that the conformational dynamics at this step of the catalytic cycle, coordinated by αFG, underlies TYK2-unique substrate recognition and accounts for its distinct specificity. In total, this work adds to knowledge towards an in-depth understanding of TYK2 activation and may be valuable towards a rational design of allosteric TYK2-specific inhibitors.

Introduction : In adults chronically infected with HIV, there is an increased prevalence of impaired respiratory function, with a greater occurrence of COPD ( Chronic obstructive pulmonary disease) than in the uninfected population. In children, data from the literature show a higher prevalence of atopy. Additionally, adolescents treated since birth for HIV infection in utero often exhibit bronchial hyperreactivity or peripheral bronchial obstruction, indicating chronic local inflammation. This study aims to evaluate the value of early detection of peripheral obstruction in HIV-infected adolescents, initiating early treatment and preventing long-term respiratory function impairment in adulthood. Methods : This prospective monocentric study included patients aged 11 to 25. Participants underwent forced oscillometry, conventional respiratory functional exploration, and completed a respiratory quality of life questionnaire. The primary endpoint was the parameter R5Hz Results : 21 teenagers were included in our study. Regarding the primary endpoint, one patient out of 13 (7.6%) showed an increase in R5Hz. Three (23%) exhibited abnormal resistance exploration. Regardless, three patients met the criteria for bronchial hyperreactivity. Concerning the questionnaire, three patients, despite having no respiratory function impairment, reported a decreased quality of life associated with breathing. Conclusion : There is probably approximately 15% of children infected with HIV at birth in France experiencing chronic lung inflammation. More accurate detection through oscillometry would enable precise identification of these children and offer them targeted treatment. This approach could not only improve their quality of life but also help preventing progressive decline in respiratory function and the development of chronic bronchopathy in adulthood.

Objective: To investigate the effects of combining Capacitive-Resistive Monopolar Radiofrequency (CRMRF) with perineal massage as manual therapy on dyspareunia-related pain and muscle strength. Design: This study utilized an experimental, analytical, longitudinal, and prospective single-blinded (patients) randomized controlled trial (RCT). Setting: The research was conducted at a university facility from November 2021 to February 2023. Population: The study involved 44 women aged between 18-30 years, experiencing pain during sexual intercourse. Methods: The participants were divided into two groups: the Intervention Group (IG) received manual therapy treatment involving perineal/Thiele massage with 448 KHz CRMRF, while the Control Group (CG) received the same treatment without CRMRF (device switched off). They underwent four sixteen-minute sessions and were evaluated at three time points: baseline, after the sessions, and three months later. Main Outcome Measures: The main outcome measures included pain during digital palpation and intracavitary stretching, vaginal dilator insertion, instrumental stretching, muscle strength, perceived pain during sexual intercourse, and perceived sexual satisfaction. Results: Significant improvements were observed in the intervention group compared to the control group. The intervention group demonstrated enhancements in measures such as manual stretching, pain during instrumental insertion, instrumental stretching, Oxford scale score, pain score, and subjective perception of sexual satisfaction. These improvements were sustained at the three-month follow-up. The control group also showed significant improvements in instrumental stretching, pain score, and subjective perception of sexual satisfaction. Conclusions: Physiotherapy, including perineal massage, provides effective pain relief for young women with dyspareunia. The incorporation of CRMRF in manual therapy improves pain perception, muscle function, and sustains its long-term effects.
