Under nature structure conditions on f and g, we classify the positive solutions for the semi-linear elliptic system involving the fractional Laplacian by using the direct method of the moving spheres introducing by W. Chen, Y. Li, and R. Zhang (“A direct method of moving spheres on fractional order equations,” J. Funct. Anal., vol. 272, pp. 4131–4157, 2017). In the half space, we establish a Liouville type theorem without any assumption of integrability by combining the direct method of moving planes and moving spheres, which improves the result proved by W. Dai, Z. Liu, and G. Lu (“Liouville type theorems for PDE and IE systems involving fractional Laplacian on a half space,” Potential Anal., vol. 46, pp. 569–588, 2017).

Abstract

Objectives
Early diagnosis of inborn errors of metabolism (IEM) is crucial to ensure early detection of conditions which are treatable. This study reports on targeted metabolomic procedures for the diagnosis of IEM of amino acids, acylcarnitines, creatine/guanidinoacetate, purines/pyrimidines and oligosaccharides, and describes its validation through external quality assessment schemes (EQA).

Methods
Analysis was performed on a Waters ACQUITY UPLC H-class system coupled to a Waters Xevo triple-quadrupole (TQD) mass spectrometer, operating in both positive and negative electrospray ionization mode. Chromatographic separation was performed on a CORTECS C18 column (2.1 × 150, 1.6 µm). Data were collected by multiple reaction monitoring.

Results
The internal and EQA results were generally adequate, with a few exceptions. We calculated the relative measurement error (RME) and only a few metabolites displayed a RME higher than 30 % (asparagine and some acylcarnitine species). For oligosaccharides, semi-quantitative analysis of an educational panel clearly identified the 8 different diseases included.

Conclusions
Overall, we have validated our analytical system through an external quality control assessment. This validation will contribute to harmonization between laboratories, thus improving identification and management of patients with IEM.
Effect of surface roughness on the interface behavior of clayey soils

Published: March 2024

Abstract
This study investigates the effect of surface roughness on the interface behavior between clayey soils and structural materials, aiming to determine the necessary parameters for soil-structural interaction. The research site, located in one of Iraq’s seismically active regions, was selected for its significance. Experimental measurements were conducted using the SRT-6210 Digital Surface Roughness Tester to assess the roughness characteristics of steel and concrete samples. Four distinct roughness parameters were measured, and their correlation with shear parameters was analyzed. The shear behavior of clay-steel and clay-concrete interfaces was successfully described using the average roughness parameter (Ra), which exhibited the strongest correlation with shear parameters. Direct shear box and interface shear box tests were employed to identify soil’s shear strength parameters and evaluate interface shear strength parameters. The experimental findings highlight the significant influence of surface roughness on the shear strength parameters of clay-steel and clay-concrete interfaces. The interface shear strength, friction angle, and adhesion exhibited an increasing trend with roughness. Notably, shear strength increased by approximately 29.76% when concrete sample roughness was below 20 μm and by 32.8% when steel sample roughness was below 30 μm. Moreover, increasing surface roughness improved the interface friction angle of clay-steel and clay-concrete samples by about 37.95 and 36.3%, respectively. Additionally, an increase in roughness led to a rise in the adhesion of concrete and steel samples by approximately 26.24 and 32%, respectively. These findings emphasize the significance of surface roughness in optimizing the interface behavior between clayey soils and structural materials. The results have important implications for enhancing the design and performance of soil-structural systems.

Abstract
Placentophagia is a natural behaviour in mammals. Although placentophagia has been reported from 18 species of bats so far, the instance from the wild are infrequent. Rousettus leschenaultii is a widely distributed species across South and Southeast Asia, and is consistently described as a common species throughout its range. However, the ecology of this species is poorly known according to the latest IUCN assessment. Through this note, we provide the first recorded instance of placentophagia and birth-associated behaviours of this species in the wild.

Abstract
The role of hepatic venous pressure gradient (HVPG) measurement in risk stratification before liver resection is an ongoing area of debate. This study examines the impact of preoperative HVPG levels on overall survival (OS)/time to recurrence (TTR) and postoperative complications after hepatic resection of hepatocellular carcinoma (HCC). Thirty-eight HCC patients undergoing HVPG measurement before liver resection at Cambridge University Hospitals NHS Foundation Trust between January 2014 and April 2022 were retrospectively analysed. Statistical analysis comprised univariable/multivariable Cox/logistic regression to identify risk factors of reduced OS/TTR or 90-day post-resection complications and Kaplan–Meier estimator, log-rank, chi-squared, Fisher's exact, and Mann–Whitney U test, or Student's t-test for survival/subgroup analysis. The median HPVG was 6 (range: 0–14) mmHg. The HVPG was an independent risk factor for poorer TTR in the overall cohort (cut-off: ≥7.5 mmHg (17.18/43.81 months; P = 0.009)). In the subgroup analysis of cirrhotic patients (N = 29 (76%)), HVPG was additionally an independent risk factor for lower OS (cut-off: ≥8.5 mmHg [44.39/76.84 months; P = 0.012]). The HVPG had no impact on OS/TTR in non-cirrhotic patients (N = 9 (24%)), nor was it associated with postoperative complications in any cohort. In conclusion, preoperative HVPG levels are useful predictors for TTR and OS in cirrhotic HCC patients undergoing hepatic resection.

Published: March 2024

Abstract
As there are no predictive models for pulmonary embolism (PE) in patients with suspected PE at cardiology department. This study developed a predictive model for the probability of PE development in these patients. This retrospective analysis evaluated data from 995 patients with suspected PE at the cardiology department from January 2012 to December 2021. Patients were randomly divided into the training and validation cohorts (7:3 ratio). Using least absolute shrinkage and selection operator regression, optimal predictive features were selected, and the model was established using multivariate logistic regression. The features used in the final model included clinical and laboratory factors. A nomogram was developed, and its performance was assessed and validated by discrimination, calibration, and clinical utility. Our predictive model showed that six PE-associated variables (age, pulse, systolic pressure, syncope, D-dimer, and coronary heart disease). The area under the curve – receiver operating characteristic curves of the model were 0.721 and 0.709 (95% confidence interval: 0.676–0.766 and 0.633–0.784), respectively, in both cohorts. We also found good consistency between the predictions and real observations in both cohorts. In decision curve analysis, the numerical model had a good net clinical benefit. This novel model can predict the probability of PE development in patients with suspected PE at cardiology department.

Published: March 2024

Abstract
With rapid development of holography, metasurface-based holographic communication scheme shows great potential in development of adaptive electromagnetic function. However, conventional passive metasurfaces are severely limited by poor reconfigurability, which makes it difficult to achieve wavefront manipulations in real time. Here, we propose a holographic communication strategy that on-demand target information is firstly acquired and encoded via a depth camera integrated with modified YOLOv5s target detection algorithm, then transmitted by software defined radio modules with long term evolution at 5 GHz, and finally reproduced in the form of holographic images by spin-decoupled programmable coding metasurfaces at 12 GHz after decoding through modified Gerchberg–Saxton algorithm. Experiments are conducted to demonstrate the brand-new concept of optical information conversion to electromagnetic one via above intelligent scheme. Our strategy may open a novel avenue toward applications of near-field communication based on adaptive variation of electric field patterns (i.e. holographic images).
Development and production of antibodies against gamma inactivated pathogenic bacterial spores
Authors: Polat Ilkay Goksu , Tazebay Uygar Halis , Akcael Esin 
Published: March 2024

Abstract

Objectives
Gram-positive sporulated bacilli can cause many different diseases and isolation from environmental samples is difficult. Therefore, the quick detection and diagnosis of these microorganisms have critical importance because of their potentially harmful situation. However, many accepted diagnostic methods exist, and future technology points to immunoassay systems. Immunological methods to detect biological microorganisms require antigen-specific high-affinity antibodies as key materials.

Methods
In this study, Bacillus anthracis (34F2 sterne) bacterium, which causes anthrax disease, was chosen as a model organism to develop antibodies against bacterial spores. The produced spores were inactivated with gamma irradiation, and the development of monoclonal antibodies against inactivated spores was performed using hybridoma technology. Also, the polyclonal antibody was successfully obtained by immunizing the rabbit. Indirect and sandwich ELISA tests were performed to determine the antigenic properties of inactivated spores and the specific affinity of the developed antibodies.

Results
The spores, inactivated with 15 kGy, have the best-preserved surface epitopic regions and were selected as immunogen. Developed monoclonal and polyclonal antibodies were shown that there was no cross-reaction with other Bacillus species. Also, it was demonstrated that these antibodies could detect inactivated spores at a concentration of 105 spores/mL in a sandwich ELISA assay.

Conclusions
These qualified antibodies obtained will be essential in developing antibody-based diagnostic systems for spore detection from various environmental samples. This study suggests that the inactivated spores are a decent immunogen for generation antibodies and may be a candidate component for live vaccine formulation.

Abstract
Universally, energy loss in the form of heat is predominant and this heat is irrecoverable waste heat that leads to global warming. Clean, green, eco-friendly, cost-effective, and renewable energy sources are the possible solutions for this energy crisis and global warming issues. Thermoelectric power generation is a promising technology by converting this irrecoverable waste heat directly into electricity without any greenhouse gas emission. Nanostructured CaMnO3 at various cerium concentrations have been successfully prepared by sol–gel hydrothermal method followed by annealing and sintering. Pure and doped samples were systematically characterized by DSC, powder XRD, RAMAN, SEM with EDAX and FTIR spectroscopy. Electrical and thermoelectrical measurements were carried out on the sintered pellets. The XRD analyses confirmed the formation of orthorhombic perovskite structure for all the samples and the average particle size lies in the range of 50–60 nm. FTIR analysis shows the presence of CaMnO3 nanoparticles without any impurities. The temperature dependence of physical properties was performed and analyzed between room temperature and 600 °C. Electrical resistivity strongly depends on the nature of substituent ions and negative values indicate that the electrons are major charge carriers.

Die Begrenztheit der Kreativität. Adam als Protomodell der Schöpfung bei Avitus von Vienne
Authors: Beier Julia Catharina 
Published: March 2024

Zusammenfassung
Die Figur des biblischen Adams als des ersten Menschen hat über die Jahrhunderte große Beachtung gefunden. Dieser Aufsatz untersucht die Rezeption der alttestamentlichen Sündenfallerzählung am Beispiel des Bibelepos De spiritalis historiae gestis des Avitus von Vienne. Der Fokus liegt hier auf der Begrenztheit des avitischen Adams, die sich durch die Ambivalenz der herausgehobenen Form der Schöpfung des Menschen als Ebenbild Gottes und der damit verbundenen Befähigung zur Kreativität einerseits und der gleichzeitigen Bestimmung Adams zum Fall andererseits ergibt.
Das Ziel des Aufsatzes besteht darin, am Beispiel Adams und Evas die Unterschiede zwischen der biblischen Erzählung und ihrer Rezeption in der Mehrzahl christlicher Schriften gegenüber derjenigen des Avitus und die Gegenwartsrelevanz des Epos vor dem Hintergrund geschlechtsspezifischer, dem Wandel unterworfener Rollenbilder zu zeigen.
Reimagining the Anthropocene in the Search for Human Security: Humans as Creating Creatures
Authors: Lautensach Sabina W. 
Published: March 2024

Abstract
The Anthropocene poses daunting challenges to humanity in the form of a polycrisis with diverse manifestations. Both the definition of the epoch and its challenges stem from our ecological overload and the domination over the biosphere by human endeavors. An organized transition to a sustainable future, as well as educational efforts to expedite it, will depend on the extent of human agency at the individual and collective levels. An analysis of precedents and current trends suggests poor chances for a successful transition out of the initial causation phase of the Anthropocene, despite our collective culpability. More likely are multiple transitions that take diverse regional approaches, with varying success rates. As human agency becomes increasingly constrained, hopes for creative solutions focus on local communities, positive deviants, and counterhegemonic education.
Theologische Deutungen von Ohnmachts- und Schulderfahrungen in der Klimakrise
Authors: Plüss David 
Published: March 2024

Zusammenfassung
Die Klimakrise fordert die gesamte Menschheit zur Umkehr heraus. Sie fordert auch die Religionen heraus, ihre Ressourcen zu mobilisieren, die zu einer Wende beitragen können. Ich gehe davon aus, dass dies nicht nur in Gestalt kirchlicher Stellungnahmen oder theologisch-ethischer Erörterungen, sondern auch und in besonderer Weise durch Gottesdienste – durch Gebete, Gesänge, Predigten – geschehen kann und geschehen soll. Der Beitrag zeigt am Fallbeispiel eines Fürbittegebets, welche semantischen und rhetorischen Strategien dafür angewendet werden und wagt ein durchaus vorläufiges Urteil in Bezug auf die Angemessenheit derselben.
Evaluating Screening to Assess Endorsement of Food Insecurity in the Inpatient Setting
Authors: Tepe Kerry A. , Auger Katherine A. , Rodas Marquez Sonia , Atarama Denise , Sauers-Ford Hadley S. 
Published: March 2024

OBJECTIVE
Rates of food insecurity (FI) from screening in the inpatient setting is often not reflective of community prevalence, indicating that screening likely misses families with FI. We aimed to determine the combination of FI screening questions and methods that would result in identifying a percentage of FI families that matched or exceeded our area prevalence (approximately 20%).

METHODS
Research staff approached eligible English- and Spanish-speaking families across 4 inpatient units once weekly and screened for FI using a randomly selected method (face-to-face, phone, paper, and tablet). We asked questions from the 6-Item USDA Survey, Hunger Vital Sign screener, and questions utilized by our social workers.

RESULTS
We screened 361 families; 19.4% (N = 70) endorsed FI. Differences in rates were not significant by method. Differences in FI rates based on screening questions were: 17.7% for the 6-item USDA survey, 16.0% for Hunger Vital Sign, and 3.1% for the social work questions. When considering method and screening questions together, the 6-Item USDA on paper had the highest positivity rate of 20.9%. A higher percentage of Spanish-speaking families endorsed FI (61.1%) compared to 17.2% of English-speaking families (P &lt; .01). Positivity also varied significantly by self-identified race (P &lt; .01). Caregivers that identified as Hispanic or Latino were significantly more likely to endorse FI than those that did not (P &lt; .01).

CONCLUSIONS
The positivity rate for FI while screening inpatient families using the 6-Item screening questions on paper matched our community prevalence of FI (approximately 20%).

Published: March 2024

BACKGROUND
Congenital toxoplasmosis (CT) can be accompanied by serious organ manifestations, particularly retinochoroiditis, and may occur throughout life. We aimed to monitor long-term ocular prognosis in a large French cohort of patients with CT and its changes over time in the context of mandatory prenatal screening (since 1992) and incidence decrease since 2008.

METHODS
Patients with CT diagnosed between 1987 and 2021 were prospectively included and followed for up to 35 years. The effect of the period of conception on the risk of first retinochoroiditis has been tested using a flexible extension of the Cox model. Incidence rates of retinochoroiditis were estimated.

RESULTS
A total of 646 infected live born children were followed for a median of 12 years (range, 0.5–35); 187 patients (29%) had at least 1 ocular lesion (first at a median age of 5 years; range, 0–26 years) with peaks at 7 and 12 years. Early maternal infection and the presence of nonocular signs at birth were associated with a higher risk of retinochoroiditis, whereas delayed diagnosis of CT (after birth versus before or at birth) was associated with a lower risk (13% decrease for each additional month after birth; P = .01). A period effect for the risk of developing retinochoroiditis in patients born after 2008 was not detected.

CONCLUSIONS
Despite prenatal screening and prolonged perinatal treatment, retinochoroiditis is not a rare event in French patients with CT and can occur well into adulthood, with peak incidences at 7 and 12 years of age. It rarely causes severe damage but warrants regular follow-up into adulthood.

Purpose: Maladaptive neuroplasticity may develop after injury. However, most of the test applications in the return to the sport process mainly focus on the motor end of the sensorimotor system. In this study, we aimed to examine the performance outputs of the functional hop tests with the dual task methodology.
Methods: Triple hop for distance (THD), crossover hop for distance (CHD) and 6-meter hop for timed (6MHT) tests were done. For the cognitive task the backward digit span test of the Wechsler intelligence scale was preferred. Nineteen athletes with a history of unilateral lower extremity injuries were assigned to the previously injured group (PIG), and 20 athletes with no previous injury were assigned to the control group (CG).
Results: There were no significant differences between the results of the cognitive task levels and Mini Mental State Examination scores of the athletes in our study (p>0.05). PIG athletes showed significantly lower jump performances compared to CG athletes; in the injured extremity side, differences were found between the groups' THD, CHD, and 6MHT values during a single task (p
