Published: January 2025

Abstract
The presence of an aberrant right hepatic artery (a-RHA) could influence the oncological and postoperative outcomes after pancreaticoduodenectomy (PD). A comparative study was conducted, including patients who underwent PD with a-RHA or with normal RHA anatomy. The primary endpoints were R1 resection in all margins (pancreatic, anterior, posterior, superior mesenteric artery, and portal groove), overall survival (OS), and disease-free survival (DFS). The secondary endpoints were morbidity, mortality, biliary leak (BL), postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), post pancreatectomy hemorrhage (PPH), length of stay (LOS), and operative time (OT). The selection bias was measured using the d-value and limited using entropy balancing analysis. Patients with arterial variants were 84 (37.5%), 39 (17.4%) of whom had a-RHA from SMA. The patients with a-RHA were more frequently symptomatic (d = 0.652), often affected by PDAC (d = 0.369), and judged borderline resectable (d = 0.588). Neoadjuvant therapy was more frequently proposed for patients with a-RHA (d = 0.465). The patients with a-RHA often had the Wirsung dilated compared to those without a-RHA (d = 0.336). After bias correction, the R1 resection rate on the superior mesenteric artery (SMA) margin was higher in the a-RHA group than in patients with normal RHA anatomy (OR 2.3; 1.1–5.2; P = 0.045). OS, DFS, morbidity, mortality, biliary leak (BL), postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), post pancreatectomy hemorrhage (PPH), length of stay (LOS), and operative time (OT) were similar in unmatched and matched population. The presence of a-RHA seems to increase the risk of R1 resection in the SMA margin.

Abstract
Only a few human ovarian endometrioid carcinoma cell lines are currently available, partly due to the difficulty of establishing cell lines from low-grade cancers. Here, using a cell immortalization strategy consisting of i) inactivation of the p16INK4a-pRb pathway by constitutive expression of mutant cyclin-dependent kinase 4 (R24C) (CDK4R24C) and cyclin D1, and ii) acquisition of telomerase reverse transcriptase (TERT) activity, we established a human ovarian endometrioid carcinoma cell line from a 46-year-old Japanese woman. That line, designated JFE-21, has proliferated continuously for over 6 months with a doubling time of ~ 55 h. JFE-21 cells exhibit polygonal shapes and proliferate without contact inhibition to form a monolayer in a jigsaw puzzle-like arrangement. Ultrastructurally, JFE-21 cells exhibit well-developed rough endoplasmic reticulum, mitochondria and lysosomes in the cytoplasm, with cells contacting each other via desmosomes. G-band karyotype analysis indicated that cells had a near-tetraploid karyotype. Immunofluorescence staining revealed that the expression profile of a series of ovarian carcinoma markers in JFE-21 cells was consistent with ovarian endometrioid carcinoma. Moreover, Sanger sequencing of DNA polymerase ε (POLE) gene and immunohistochemical analysis of mismatch repair (MMR) proteins revealed that JFE-21 cells were classified as the no specific molecular profile (NSMP) subtype. In addition, JFE-21 cells were sensitive to paclitaxel and carboplatin administered to the donor as therapy. These findings indicate that constitutive expression of CDK4R24C, cyclin D1 and TERT genes may be an option to establish cell lines from low-grade cancers, including ovarian endometrioid carcinoma.
The Role of Selected Adjuncts in the Management of the Bleeding Trauma Patient: Calcium and Vasopressin
Authors: Leon David , Levy Matt , Sikorski Robert 
Published: January 2025

Abstract

Purpose of Review
This review summarizes emerging literature on calcium and vasopressin as pharmacological adjuncts in management of hemorrhage in trauma patient resuscitation, and how they may prove useful in promoting hemostasis, reduce blood product usage and improve mortality in trauma patients with hemorrhage.

Recent Findings
Hypocalcemia has correlation with mortality and increased blood product usage in trauma patients. Calcium’s role in coagulation cascade may indicate use as early supplementation before transfusion in addition to repletion in hemorrhagic shock and MTP scenarios.
Vasopressin has roles in vascular tone and coagulation, and early studies show a reduction in overall blood product usage without significant adverse events when used in hemorrhaging trauma patients, though effect on overall mortality requires further investigation.

Summary
Calcium and vasopressin are promising pharmacologic adjuncts to transfusion in bleeding trauma patients. Additional research is needed for safety and efficacy in both therapies and for other potential pharmacologic options in their role for promoting hemostasis and reducing hemorrhage severity in bleeding trauma patients.
Food, power and agency: revealing local post-harvest fisheries practices to improve food access from small-scale fisheries in coastal Kenya
Authors: Allegretti Antonio , Omukoto Johnstone O. , Hicks Christina C. 
Published: January 2025

Abstract
This article proposes the case of Kenyan coastal fisheries as a potentially crucial reservoir of food-related benefits for the marginalised and those living in poverty, but where a food-centred lens or approach is seldom mainstreamed in local and national governance. Borrowing insights from post-structuralist marine social sciences, this article presents an ethnographic account of grassroots practices in-the-making such as handling, sorting, and allocating fish once caught, and how these practices lead to local categorisations and classifications of fish. This sort of evidence and knowledge around local categorisations and classifications of fish spotlights the importance of considering the post-harvest sector (as opposed to the activity of fishing alone), that is, how the use of catch determines access through micro relations of power and agency. Through the analysis of two different locations of Watamu and Shimoni in terms of the fisheries economy and overall development, the analysis of these categories and classifications highlights the necessity to account for a fairer access and distribution rather than solely production (of fish) that is overly market-oriented.
Barriers and enhance strategies for green supply chain management using continuous linear diophantine neural networks

Published: January 2025

Abstract
Artificial neural networks, a major element of machine learning, focus additional attention on the decision-making process. We extended the idea of artificial neural networks to continuous linear Diophantine fuzzy neural networks. A few operational concepts for continuous linear Diophantine fuzzy sets are further developed, and they are subsequently made simpler to apply to more than two such sets. Also, a real multi-criteria decision-making problem has been formulated. The environment plays a very important role in our daily lives. We cause different types of pollution in our environment, and it has a bad impact on our lives. Air pollution is one of the various forms of pollution that is thought to affect the entire globe. Millions of people die due to air pollution, and industries are the main contributors to air pollution. To overcome air pollution, green supply chain management plays a vital role, but green supply chain management faces some barriers as well. According to the proposed model,

$${\mathfrak{R}}_{1}$$

R

is the best alternative and green supply chain management faces financial problems more than other barriers and also provides strategies to overcome financial barriers. In addition, a comparative analysis develops to illustrate the reliability and feasibility of the suggested technique in relation to current techniques.
Thinking About Suicidal Thinking: Suicide-Related Metacognitions’ Relation to Maladaptive Processing of Suicidal Thoughts
Authors: Forkmann Thomas , Fiorentino Laura , Müßeler Sarah Sophie , Schüler Jil , Heilmann-Stiegler Tobias , Barke Antonia , Teismann Tobias 
Published: January 2025

Abstract

Objective
The metacognitive model of suicidality proposes that positive metacognitions about suicide (PMS) activate a cognitive attentional syndrome (CAS), i.e., suicide-specific rumination, attentional fixation, and thought suppression, which in turn activates negative metacognitions about suicide (NMS) and an aggravation of suicidality. Preliminary evidence supports the model assumptions; however, a more comprehensive investigation is missing by now.

Methods
One hundred eighty-six participants (148 female [79.6%]; age M = 28.3 (SD = 9.8)) with lifetime suicidal ideation filled in self-report measures of suicide ideation/behavior, all CAS-components, and metacognitions about suicide.

Results
All elements of the CAS correlated significantly with each other and with concurrent suicidal ideation. PMS predicted suicide-specific rumination and attentional fixation. All CAS-components predicted NMS. Suicide-specific rumination, attentional fixation, and positive and negative metacognitions differentiated between lifetime suicide attempters and non-attempters.

Conclusion
Results are in line with the metacognitive model of suicidality and warrant further studies regarding the model assumptions.

Published: January 2025

Abstract

Purpose
This paper proposes a more efficient methodology of calculation than methodologies proposed by literature for the design of Buckling Restrained Braces (BRBs) in the framework of the Performance-Based Earthquake Engineering (PBEE).

Methods
The methodology is based on non-linear dynamic analyses with multiple scaled records to each PBEE level and the statistical treatment of the results. As a case study, a PC-BRB all-steel type has been applied to a RC 8-story frame structure. The BRB used in this research is a pinned diagonal type. The fundamental parameters of BRBs to attend PBEE requirements it was firstly established and a complete methodology to retrofit a reinforced concrete frame were finally proposed.

Results
Very promising results are discussed. As for example, it has been demonstrated that the initial values obtained from a static simplified method are appropriate as the first stage of the design process.
Combining approaches for improving preschoolers’ narrative production skill
Authors: Chlapana Elissavet , Koniou Antonia 
Published: January 2025

Abstract
The development of the narrative production skill is one of the most essential goals set for young children’s literacy. Different practices, such as story reading, direct instruction, and playful learning, are proposed for fostering young children’s meaning-related skills, among which is narrative production. Considering the above, the purpose of the present study is to examine the effect of a two-month intervention program on preschoolers’ narrative production skills. The design of the intervention program is based on the combination of story reading, direct instruction, and playful learning for enhancing skills directly related to the narrative production skill. For the needs of the present study, a semi-experimental study was carried out. Sample children (Ν = 32) were divided into an experimental group and a control group. The results of the present study, as they were evaluated through a norm-referenced criterion, showed the effectiveness of the proposed intervention on preschoolers’ narrative production skills, especially in relation to their ability to make inferences that interpret the story characters’ actions and emotional state.
Vision-based welding quality detection of steel bridge components in complex construction environments

Published: January 2025

Abstract
Currently, welding quality detection remains dependent on manual operation, while the increase in the span and intricacy of steel bridges has rendered the conventional method of detection insufficient to fulfill the engineering requirements. This paper presents a systematic study of welding quality detection of steel bridges based on fusion of point clouds and images in complex construction environments. (1) A welding detection system is developed that could filter out stray light and capture weld images. (2) This paper enhances the centerline extraction method in 3D reconstruction, which could effectively filter out noise interference and precisely reconstruct weld contours. The contour dimensions of both filler and cover welds are identified through feature point extraction, with an estimated detection error under 0.6%. (3) This paper optimizes the feature extraction of the Faster R-CNN network based on the appearance feature and detection need of welding defects, resulting in an improvement of 28.3 in mAP. Experimental results demonstrate that the proposed welding quality detection is both efficient and accurate, and is capable of meeting the requirements of actual steel bridge construction.
Four-port flexible UWB-MIMO antenna with triple band-notched for wearable IoT applications
Authors: Peng Huanchen , Du Chengzhu , Wang Ruohui 
Published: January 2025

Abstract
A four-port ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna with three notch bands is proposed in this work. The antenna uses ultra-thin flexible material liquid crystal polymer (LCP) as the substrate. Four identical monopole radiators are designed in this proposed antenna system. The notch bands of the antenna are generated by adding complementary split ring resonator (CSRR) and ring branch. A cross-shaped stub is set in the center of the four antenna units to enhance the isolation. The measured bandwidth of the antenna is 2.54–10.69 GHz, filtering out three notch frequency bands of 2.81–3.85, 5.11–5.98, and 7.34–8.69 GHz. The isolation in the entire working frequency is better than 22 dB. The bent performances of the MIMO system and the specific absorption rate (SAR) value are analyzed. The low SAR values, low envelope correlation coefficient (<0.05), high diversity gain (>9.999), and stable gain of the proposed antenna indicate that in UWB-MIMO systems and wearable Internet of Things applications, it can be widely used.
Numerical and Observational Study of Sn‐To‐Lg Conversion Due To Crustal‐Thickening: Implications for Identification of Continental Mantle Earthquakes
Authors: Wang Shiqi , Klemperer Simon L. 
Published: January 2025

AbstractWe study Sn‐to‐Lg conversion due to significant crustal‐thickening, using Sn and Lg amplitude ratios (Sn/Lg) to identify continental mantle earthquakes. We perform 2.5D simulations up to 5 Hz and 2,000 km using an enhanced AxiSEM3D. Our simulations compare propagation in a constant‐thickness crust from a source at three depths straddling the Moho, to 48 models of the same three sources propagating through Moho ramps of four different widths (dips) at four different distances from the source, so perturbations of Sn/Lg are only due to crustal‐thickening. We compare our synthetics to data from 12 earthquakes recorded on the HiCLIMB array across Tibet, of which six previously studied events from northwestern Tibet traverse no major crustal‐thickness variation, and six new events are located south of the Himalaya across a major Moho ramp. Our simulations show that Sn/Lg for mid‐crustal earthquakes is consistently lower than for mantle earthquakes, especially for areas beyond the end of the ramp. Our observations on real data, with similar travel paths for each group of events (ramp‐crossing and non‐ramp‐crossing), display bi‐modal separation of Sn/Lg for both groups, identifying new mantle earthquakes in northern India. Sn‐to‐Lg converted waves may be readily detected by enhanced high‐frequency Lg content, as suggested by previous mode‐coupling studies, verified here with synthetics, and observed in data. Lastly, we observe higher frequency content in Lg from crustal earthquakes than from mantle earthquakes in simulations and in data, offering a new discriminant for continental mantle earthquakes based on frequency content of Lg waves alone.
The genetics of neurodegenerative diseases is the genetics of age-related damage clearance failure
Authors: Hardy John , Escott-Price Valentina 
Published: January 2025

Abstract
In this perspective we draw together the data from the genome wide association studies for Alzheimer’s disease, Parkinson’s disease and the tauopathies and reach the conclusion that in each case, most of the risk loci are involved in the clearance of the deposited proteins: in Alzheimer’s disease, the microglial removal of Aβ, in the synucleinopathies, the lysosomal clearance of synuclein and in the tauopathies, the removal of tau protein by the ubiquitin proteasome. We make the point that most loci identified through genome wide association studies are not strictly pathogenic but rather relate to failures to remove age related damage. We discuss these issues in the context of copathologies in elderly individuals and the prediction of disease through polygenic risk score analysis at different ages. Finally, we discuss what analytic approaches are needed now that we have adequately sized case control analyses in white populations.

Abstract
Early investigation revealed a reduced risk of SARS-CoV-2 infection among social contacts of COVID-19 vaccinated individuals, referred to as indirect protection. However, indirect protection from SARS-CoV-2 infection-acquired immunity and its comparative strength and durability to vaccine-derived indirect protection in the current epidemiologic context of high levels of vaccination, prior infection, and novel variants are not well characterized. Here, we show that both vaccine-derived and infection-acquired immunity independently yield indirect protection to close social contacts with key differences in their strength and waning. Analyzing anonymized SARS-CoV-2 surveillance data from 9,625 residents in California state prisons from December 2021 to December 2022, we find that vaccine-derived indirect protection against Omicron SARS-CoV-2 infection is strongest within three months of COVID-19 vaccination [30% (95% confidence interval: 20–38%)] with subsequent modest protection. Infection-acquired immunity provides 38% (24–50%) indirect protection for 6 months after SARS-CoV-2 infection, with moderate indirect protection persisting for over one year. Variant-targeted vaccines (bivalent formulation including Omicron subvariants BA.4/BA.5) confer strong indirect protection for at least three months [40% (3–63%)]. These results demonstrate that both vaccine-derived and infection-acquired immunity can reduce SARS-CoV-2 transmission which is important for understanding long-term transmission dynamics and can guide public health intervention, especially in high-risk environments such as prisons.
Transition from the topological to the chaotic in the nonlinear Su–Schrieffer–Heeger model

Published: January 2025

Abstract
Recent studies on topological materials are expanding into the nonlinear regime, while the central principle, namely the bulk–edge correspondence, is yet to be elucidated in the strongly nonlinear regime. Here, we reveal that nonlinear topological edge modes can exhibit the transition to spatial chaos by increasing nonlinearity, which can be a universal mechanism of the breakdown of the bulk–edge correspondence. Specifically, we unveil the underlying dynamical system describing the spatial distribution of zero modes and show the emergence of chaos. We also propose the correspondence between the absolute value of the topological invariant and the dimension of the stable manifold under sufficiently weak nonlinearity. Our results provide a general guiding principle to investigate the nonlinear bulk–edge correspondence that can potentially be extended to arbitrary dimensions.
