Published: September 2024

Abstract
Objective
To develop an ensemble machine learning (eML) model using multiphase computed tomography (MPCT) for distinguishing between gastric ectopic pancreas (GEP) and gastric stromal tumors (GIST) in lesions < 3 cm.

Methods
In this study, we retrospectively collected MPCT images from 138 patients between April 2017 and June 2023 across two centers. Cohort 1 comprised 94 patients divided into a training cohort and an internal validation cohort, while the 44 patients from Cohort 2 constituted the external validation cohort. Deep learning (DL) models were constructed based on the lesion region, and radiomics features were extracted to develop radiomics models, which were later integrated into the fusion model. Model performance was assessed through the analysis of the area under the receiver operating characteristic curve (AUROC). The diagnostic efficacy of the optimal model was compared with that of a radiologist. Additionally, the radiologist with the assistance of the eML model provides a secondary diagnosis, to assess the potential clinical value of the model.

Results
After evaluation using an external validation cohort, the radiomics model demonstrated the highest performance in the venous phase, achieving AUROC of 0.87. The DL model showed optimal performance in the non-contrast phase, with AUROC of 0.81. The eML achieved the best performance across all models, with AUROC of 0.90. The use of eML-assisted analysis resulted in a significant improvement in the junior radiologist’s accuracy, rising from 0.77 to 0.93 (p < 0.05). However, the senior radiologist’s accuracy, while improving from 0.86 to 0.95, did not exhibit a statistically significant difference.

Conclusion
eML model based on MPCT can effectively distinguish between GEPs and GISTs < 3 cm.

Critical relevance statement
The multiphase CT-based fusion model, incorporating radiomics and DL technology, proves effective in distinguishing between GEP and gastric stromal tumors, serving as a valuable tool to enhance diagnoses and offering references for clinical decision-making.

Key Points

No studies yet differentiated these tumors via radiomics or DL.

Radiomics and DL methodologies unveil potentially distinct phenotypes within lesions.

Abstract
Background
Idiopathic intracranial hypertension (IIH) is a disease of raised intracranial pressure. Contribution of inflammatory mediators has been suggested in IIH pathophysiology. The aim of this study was to estimate certain serum inflammatory markers in IIH patients compared to normal subjects. Also, to examine the correlation between these laboratory parameters and the clinical and radiological characteristics of IIH patients.

Results
Body mass index (BMI) was significantly higher among IIH patients compared to controls. Serum LDH, CRP, NLR and PLR were significantly higher, whereas serum iron was significantly lower in IIH patients compared to healthy controls. IIH patients with stenosis in brain MRV had significantly higher mean serum CRP compared with patients with normal MRV. There was a statistically significant positive correlation between serum CRP and the presence of stenosis in MRV, between serum LDH level and grade of papilledema, and between CRP, TIBC, and NLR with BMI.

Conclusions
There is a significant elevation of inflammatory markers in IIH patients. Moreover, cerebral venous sinus stenosis and BMI were positively associated with higher markers of inflammation as CRP, LDH and NLR indicating the role of inflammation in thrombosis and obesity associated with IIH.

Abstract
Background
Neck pain is the most common musculoskeletal complexity with a high prevalence, especially in adults and the elderly.

Objectives
The objective of our study is to investigate the prevalence and associated factors of neck pain in research and development department staff in Bangladesh.

Methodology
Data were collected through questionnaire-assisted interviews to investigate the prevalence and related factors of neck pain among 384 R&D employees aged 18–55 years in Bangladesh. We performed regression analysis on neck pain and associated risk factors to uncover its sociodemographic and occupational correlates.

Results
The neck pain prevalence was high in this investigation, which is 35.7%, and of these, 27.6% affected the general working ability of the employees. The results indicated that people aged 40 to above years were more significantly to have neck pain, with an OR of 6.148 (p = 0.046), and BMI results indicated that those who were underweight were slightly significantly to have pain (p < 0.001). Again, educational qualification especially HSC or diploma OR 15.600 (p = 0.020) and those who often work on the computer were more significantly to have neck pain, with OR 8.801 (p = 0.078).

Conclusions
This study showed that the prevalence of neck pain was high among R&D workers in private industry. In this investigation, several factors associated with neck pain were found through logistic regression evaluation. The results of this study indicated that age, BMI, educational qualification, and those who frequently worked on computers had higher neck pain.
Effects of overconsolidation on seismic rock physics — A comparative study between unconsolidated sands and weakly cemented sandstone
Authors: Yu Jiaxin , Avseth Per , Duffaut Kenneth 
Published: September 2024

In seismic rock physics, models typically assume rocks are normally consolidated, often neglecting the effects of overconsolidation. Recent studies reveal that overconsolidated sands, resulting from stress release, show different physical property variations than normally consolidated sands. However, similar research is lacking for weakly cemented sandstones, a common reservoir analog. This study aims to systematically compare the effects of overconsolidation and stress direction on unconsolidated sandstones and weakly cemented sandstones. It also assesses the impact of overconsolidation on seismic interpretation, monitoring, and rock-physics modeling applied to these two types of rocks. Experimental measurements of porosity, P-wave, and S-wave velocities were collected under different stress paths between loading and unloading. For weakly cemented sandstone, well-log data from the Norwegian Sea and Barents Sea were compared with experimental data. Analyses focused on the velocity-porosity relationship, [Formula: see text]/[Formula: see text] ratio versus AI, and [Formula: see text]/[Formula: see text] ratio versus effective stress. Results show that overconsolidation and stress direction affect these attributes differently in both rock types. The [Formula: see text]/[Formula: see text] ratio of unconsolidated sand remains stable under stress changes, whereas weakly cemented sandstone shows significant variation. Rock-physics modeling suggests that the stress sensitivity of the [Formula: see text]/[Formula: see text] ratio in overconsolidated weakly cemented sandstone under saturated conditions depends on the extent of cement deterioration. Strong cement deterioration upon unloading increases stress sensitivity, whereas less destructive deterioration decreases it. Experimental data align with models assuming strong deterioration, whereas field data from uplifted areas fit models assuming less destructive deterioration. This work highlights the importance of considering overconsolidation in rock-physics models and reveals pitfalls in applying existing models and workflows to overconsolidated reservoir rocks.

Published: September 2024

Abstract
The cantilever tip of a nanoswitch in close proximity to the ground plate is considered with account of electrostatic, elastic, van der Waals (Casimir), and also contact repulsive forces. The van der Waals (Casimir) and contact repulsive forces are computed for a Si cantilever and either Au or Ni ground plates using the Lifshitz theory and the method of pairwise summation with account of surface roughness. It is shown that at short separations an impact of the van der Waals (Casimir) force leads to the pull-in and collapse of a cantilever onto the ground plate if the contact repulsion is disregarded. Taking into consideration contact repulsion, the nanoswitch is demonstrated to have the stable cyclic behavior with no pull-in when switching voltage on and off.
Bistability in the sunspot cycle
Authors: Vashishtha Sumit , Sreenivasan Katepalli R. 
Published: September 2024

Abstract
A direct dynamical test of the sunspot cycle is carried out to indicate that a stochastically forced nonlinear oscillator characterizes its dynamics. The sunspot series is then decomposed into its eigen time-delay coordinates. The relevant analysis reveals that the sunspot series exhibits bistability, with the possibility of modeling the solar cycle as a stochastically and periodically forced bistable oscillator, accounting for poloidal and toroidal modes of the solar magnetic field. Such a representation enables us to conjecture stochastic resonance as the key mechanism in amplifying the planetary influence on the Sun, and that extreme events, due to turbulent convection noise inside the Sun, dictate crucial phases of the sunspot cycle, such as the Maunder minimum.
Non-Aristotelian Elements in Carl Menger's Methodology
Authors: Slenzok Norbert , Turowski Krzysztof 
Published: September 2024

Abstract
According to the dominant interpretation, Carl Menger, the founder of the Austrian school, was an Aristotelian methodologist of social science. As this article attempts to demonstrate, this influence was not decisive in shaping Menger's methodology. In fact, Menger shared several core positions with modern thinkers. Such non-Aristotelian threads in Menger tackled in the article encompass his views on essentialism and realism, a priori knowledge, the classification of sciences, and scientific value-freedom, as well as methods of historical inquiry. As is shown, while unattachable to any specific philosophical school, those five elements constitute a fairly consistent, non-Aristotelian account of economic methodology.
Chartalism in Ancient China: A Retrospective of Monetary Thought
Authors: He Zengping 
Published: September 2024

Abstract
Chartalism is an influential and continuous tradition of monetary thought in ancient China. It dates back to the earliest Chinese text on monetary thought and continued into the Qing Dynasty. A vast body of related literature can be found across ancient Chinese dynasties. Chartalism in ancient China had the following main propositions. First, money originated as an invention of ancient monarchs and is a creature of the state. The second is the nominal theory of money: useless metal can function as money and become a tool of state intervention in the economy through state support. Third, the right to issue money should be monopolized by the state; otherwise, the state's monetary policy will be interfered with by other currencies. Fourth, an important monetary policy is the government's buying and selling of commodities countercyclically by issuing and receiving money, thus stabilizing prices. Fifth, the circulation process of sovereign money consists of two parts: the state's minting of coins (or issuing of paper money) and spending are the outflow of money, and levying monetary taxes (or selling goods) is the inflow of money. The state stabilizes the value of money by intervening in the circulation process.
Cingulin–nonmuscle myosin interaction plays a role in epithelial morphogenesis and cingulin nanoscale organization
Authors: Rouaud Florian , Maupérin Marine , Mutero-Maeda Annick , Citi Sandra 
Published: September 2024

ABSTRACT
Cingulin (CGN) tethers nonmuscle myosin 2B (NM2B; heavy chain encoded by MYH10) to tight junctions (TJs) to modulate junctional and apical cortex mechanics. Here, we studied the role of the CGN–nonmuscle myosin 2 (NM2) interaction in epithelial morphogenesis and nanoscale organization of CGN by expressing wild-type and mutant CGN constructs in CGN-knockout Madin–Darby canine kidney (MDCK) epithelial cells. We show that the NM2-binding region of CGN is required to promote normal cyst morphogenesis of MDCK cells grown in three dimensions and to maintain the C-terminus of CGN in a distal position with respect to the ZO-2 (or TJP2)-containing TJ submembrane region, whereas the N-terminus of CGN is localized more proximal to the TJ membrane. We also show that the CGN mutant protein that causes deafness in human and mouse models is localized at TJs but does not bind to NM2B, resulting in decreased TJ membrane tortuosity. These results indicate that the interaction between CGN and NM2B regulates epithelial tissue morphogenesis and nanoscale organization of CGN and suggest that CGN regulates the auditory function of hair cells by organizing the actomyosin cytoskeleton to modulate the mechanics of the apical and junctional cortex.

Published: September 2024

ABSTRACT
The ability to manipulate gene expression is valuable for elucidating gene function. In the fission yeast Schizosaccharomyces pombe, the most widely used regulatable expression system is the nmt1 promoter and its two attenuated variants. However, these promoters have limitations, including a long lag, incompatibility with rich media and unsuitability for non-dividing cells. Here, we present a tetracycline-inducible system free of these shortcomings. Our system features the enotetS promoter, which achieves a similar induced level and a higher induction ratio compared to the nmt1 promoter, without exhibiting a lag. Additionally, our system includes four weakened enotetS variants, offering an expression range similar to that of the nmt1 series promoters but with more intermediate levels. To enhance usability, each promoter is combined with a Tet-repressor-expressing cassette in an integration plasmid. Importantly, our system can be used in non-dividing cells, enabling the development of a synchronous meiosis induction method with high spore viability. Moreover, our system allows for the shutdown of gene expression and the generation of conditional loss-of-function mutants. This system provides a versatile and powerful tool for manipulating gene expression in fission yeast.
Do seabirds dream of artificial lights? Understanding light preferences of Procellariiformes

Published: September 2024

ABSTRACT
Seabirds, and particularly fledglings of burrow-nesting species, are greatly impacted by light pollution. During their inaugural flights from colony to sea, fledglings become grounded after encountering artificial light. Such groundings, or fallout events, affect many fledglings each year, causing mass mortality events. To mitigate this light-induced mortality, rescue programmes have been implemented for decades at many locations worldwide. Despite the notoriety of fallouts and their conservation implications, the contributing behavioural and biological factors remain mostly unknown. How the mechanisms of light attraction and light avoidance interact and how they manifest in different groups (e.g. age, personality, populations) or light pollution levels remain open questions. We tested behavioural choices of Cory's shearwater Calonectris borealis fledglings, rescued after being grounded in urban areas, and choices of breeding adults for contrasting light sources. Fledglings and adults were exposed to one of three treatments in an experimental Y-maze set-up: white light versus no light, blue versus red light, and a control with no light on each arm of the Y-maze. Both age groups clearly chose the no-light arms and the red light arm. This choice for longer wavelengths and darker environments, along with slower responses by fledglings, suggests that close range artificial light causes disorientation in seabirds. Our study helps to clarify the behavioural components of fallouts and provides further evidence on the disruptive effects of nocturnal artificial light on sensitive species like Procellariiformes.

Badanie miało na celu określenie znaczenia zasobów osobistych takich, jak samoocena, poczucie własnej skuteczności, motywacja do uczenia się i poczucie bezradności oraz wyników egzaminu zewnętrznego poprzedzającego naukę w szkole średniej w wyjaśnianiu osiągnięć szkolnych uczniów szkół średnich. Próba składała się z 489 uczniów trzecich klas szkoły średniej, w tym 220 licealistów, 161 uczniów techników i 108 zasadniczych szkół zawodowych. Hierarchiczna analiza regresji wskazała, że zasoby osobiste i typ szkoły były istotnymi predyktorami osiągnięć szkolnych (R2 = .279). Najważniejszym z nich była motywacja (β =.325). Potwierdzono też pośredniczącą rolę motywacji, poczucia skuteczności i poczucia bezradności w związku między samooceną a osiągnięciami szkolnymi (PROCESS macro). Dodanie do modelu wyników egzaminów zewnętrznych poprawiło znacząco jego jakość. Modelowanie równań strukturalnych potwierdziło dobre dopasowanie modelu (χ2 = 62.20, df = 18, p < .001; CFI = .974; TLI = .946; SRMR = .033; RMSEA = .071). Model wyjaśnił ponad połowę (R2 = .617) zmienności osiągnięć szkolnych uczniów szkół średnich.

This study investigated the insecticidal efficacy of essential oils (EOs) extracted from Ageratum conyzoides, Hyptis suaveolens, and Ocimum basilicum against female Anopheles mosquitoes, aiming to explore their potential as alternatives to synthetic insecticides amidst rising resistance issues. EOs were obtained through steam distillation from freshly harvested plant aerial parts, and their chemical compositions were analyzed using gas chromatography-mass spectrometry. The results revealed significant variations in chemical profiles among the oils, with precocene I dominating in A. Conyzoides, eucalyptol in H. suaveolens, and estragole in O. basilicum. Thin layer chromatography analyses revealed various components with rf values ranging from 0.25 – 0.93. Mosquito bioassay demonstrated varying knockdown effects across the oils, with H. suavolens achieving 77.5% knockdown within six minutes of the observation period. None of the oils or their combinations reached susceptibility status (98–100% mortality), indicating prevalent resistance among the mosquito population in the study area. The combination of A. conyzoides and H. suavolens essential oil gave the highest percentage mortality (70%) at the least time (9 minutes), this is a suggestion of synergistic activity. Despite resistance challenges, this study highlights the promise of botanical insecticides in sustainable mosquito control and underscores the ongoing need for innovation and adaptation in vector management strategies.
