Authors: Vashisth Anuj K. , Singh Milap , Yadav Isha , Kumar Rajesh , Dutta Shankar
Published: February 2024

MEMS based inertial switches have important applications in defense, automobile, and aviation sectors. The materials for these inertial switches are either metals or low-resistivity silicon. This paper discussed about the amalgamation of metal and silicon in the MEMS inertial switch (500 g) structure to achieve high performance and high current handling capability. The switch structure, comprises of four series-parallel beam supported large proof-mass suspended over a gap of 4 µm. The resonant frequency of the switch structure is found to be 4.2 kHz. The dimensions of the switch structure are studied by parametric analysis. The transient response of the gold coated silicon MEMS inertial switch structure showed contact (on-state) duration of 230–380 µs due to the 10% variation in half-sine threshold acceleration value (500 g). The variation in acceleration input pulse width (0.25–1 ms) yielded a large variation in contact duration (2.5–370 µs). In response to two successive half-sine acceleration pulses, variation in contact duration is observed due to the superimposition of residual movement of the proof-mass arising due to first pulse with the response of the second acceleration pulse. The electro-thermal behaviour (under 1A current flow in the switch contact duration) of the gold coated (1.0 µm) switch structure showed a substantial reduction in temperature rise (due to Joule heating) from 413 K to 301 K. Thus, the gold coating on the silicon MEMS inertial switch lowered on-state resistance by one order and improved current handling capability due to less Joule heating issue.

Published: February 2024

Introduction:
Hepatocellular carcinoma (HCC) prevails in Taiwan, primarily attributed to the high incidence of hepatitis B and hepatitis C infections with high recurrent rates of 50-70% within five years after initial treatment. When confronted with recurrent HCC, treatment options include salvage liver transplantation, trans-arterial chemo-embolization (TACE), re-hepatectomy, and radio-frequency ablation (RFA). Notably, repeat hepatectomy exhibits superior oncological outcomes compared to alternative approaches. While laparoscopic liver resection (LLR) has demonstrated safety and feasibility in primary HCC resection, the persistence of intra-hepatic recurrence necessitates effective interventions. However, repeat liver resection posed challenges, including adhesions from previous surgeries, limited access to recurrent tumors, altered liver structure post-regeneration, difficulties in obtaining hilar control, and compromised liver reserve.
Patients and methods:
We retrospectively review our collective experience spanning January 2009 to December 2021, encompassing 57 patients with recurrent HCC. Among them, 37 patients underwent laparoscopic approaches, while 20 patients opted for traditional procedures.
Results:
Notably, both groups exhibited similar operative times and perioperative outcomes, with significantly reduced hospital stays observed in the laparoscopic cohort (median: 5 vs 7, p<0.001). The introduction of laparoscopic techniques also sparked a strategy shifting in our surgical approach to recurrent HCC.
Conclusion:
Our manuscript aims to delineate a stepwise approach for navigating the challenges inherent in repeat operations, elucidating techniques for peritoneal cavity entry, meticulous adhesiolysis, effective Pringle maneuver application, tumor identification, and pertinent insights into perioperative outcomes. Under the stepwise approach, laparoscopic repeat liver resection can be performed safely and effectively with low incidence of conversion. This treatment choice should be offered to the patient in a mature surgical team of minimal invasive liver resection.

Authors: Rodríguez-Gallego Isabel , Corrales-Gutierrez Isabel , Gomez-Baya Diego , Leon-Larios Fatima
Published: February 2024

Background: There are numerous recognized benefits of breastfeeding,however, sociocultural, individual, and environmental factors influence its initiation and continuation; sometimes leading to breastfeeding rates during the postpartum period that are lower than recommended by international guidelines.The aim of this study was to evaluate the effectiveness of a group intervention led by midwives supporting breastfeeding during the postpartum period in promoting exclusive breastfeeding up to when the newborn reached 4 months of age, as well as, to assess the impact of this intervention on perceived self-efficacy and its relationships with the duration and exclusivity of breastfeeding.
Methods: A multicentric cluster randomized controlled trial with a control group and an intervention group and was not blinded. Participant recruitment began in October 2021 and ended in May 2023.A total of 382 women from Andalusia (Southern Spain) participated in the study.The control group received usual care, while the intervention group also participated in a postpartum breastfeeding support group led by a midwife. The main variables were measured during the postpartum visit and when the newborn was 2 and 4 months old.
Results: At 4 months postpartum, there was a higher prevalence of breastfeeding in the intervention group compared to formula feeding (p = 0.01), as well as a higher prevalence of exclusive breastfeeding (p= 0.03). Perceived self-efficacy was similar in both groups, with slightly higher initial scores in the intervention group than in the control group. From the beginning of the postpartum period to 2 months, there was a notable increase in self-efficacy (control group = 56.15 ± 11.01 vs intervention group = 59.75 ± 9.64), which then remained stable until 4 months (control group = 55.87 ± 13.03 vs intervention group = 59.96 ± 11.04). The intervention improved the average scores of perceived self-efficacy and indirectly caused higher rates of exclusive breastfeeding, an effect observed especially at 4 months postpartum (p= 0.005).
Conclusions: The midwife-led group intervention supporting breastfeeding during the postpartum period proved to be effective at maintaining exclusive breastfeeding at 4 months postpartum and also at increasing perceived self-efficacy.

DFT Analysis of Charge Distribution and Electrostatic Potential in SiO 2 Ring Clusters with Different Planar Folds
Authors: Mekky Abdel-baset H.
Published: February 2024

Nano-sized SiO2 ring clusters have been on the rise as intriguing blocks of structures that presently involve multifarious applications. Electric, mechanical, and chemical properties distinguish these. A full picture of their behavior has not been discovered. In our work, we delve into the fundamental aspects of SiO2 ring clusters; the goal being to elucidate their characteristic features and the pathways to an engineer to purpose. We use density functional theory (DFT) calculations for the optimization of geometries, energies, and charges of SiO2 ring clusters. MEP analysis of the molecular surface is also involved to see the electrostatic behavior. The Mulliken charge atomic computations help in deciphering how charge allocation and polarity are dependent on atoms within the clusters. The nucleophilic character of oxygen atoms is very high in comparison with silicon which shows electrophile features. Poles are located at the regions connecting aforementioned atoms, making clusters reactive. The MEP analysis shows the big range of interconnected properties. Considerably, the plane fold- a geometrical classifier- modifies notably the surface potential shapes. Different folds result in distinct charge environments. The one closest atom to the centers of the smallest ring (planar fold) is the crucial factor. It bears symmetry, stability, and reactivity. Getting this influence is very important for the synthesis of the SiO2 ring cluster. In essence, our study connects the theoretical underpinning with the practical ramifications, highlighting the critical interplay between charge allocation, electric potential, and shape features. Through exploiting these perspectives, scientists can bring the production process of cutting-edge nanomaterials to a higher level. Our results prove that nanoscale systems engineering appeared.

Published: February 2024

Poly(ethylene-alt-maleic anhydride), PEMA, and modified PEMA with pendant poly(ethylene glycol) oligomers (PEG3, PEG10, PEG20) in anhydrous acetone were grafted onto mechanically produced cellulose microfibrils, CNF. The grafted CNF had up to 4.7 mmol/g of carboxylic acid groups from the hydrolyzed PEMA. Before and after grafting, the concentrations of individualized microfibrils were low (< 10% wt/wt). Atomic force microscopy revealed that the main CNF components were intermeshed microfibrils, microfibril bundles, and ribbons a few µm wide. Mastersizer particle size distributions were usually bimodal, with 10–20 µm and 100–200 µm peaks. We proposed the smaller peaks were individualized ribbons and the larger were flocculated ribbons and microfibrils. Based on the images of dried ribbons adsorbed on cationic glass and the shapes of aqueous ribbons sitting near the non-adhesive anionic glass, the PEMA-treated ribbons were stiffer than the PEMA-PEG grafted ribbons. Perhaps the high anhydride concentration on PEMA facilitated more crosslinking of the CNF surfaces compared to PEMA-PEG polymers with about 10 times less reactive anhydride groups. There was evidence that PEG-rich grafted polymers partially inhibited the formation of CNF aggregates in water.

Published: February 2024

Purpose. Advanced Footwear Technology (AFT) are performance enhancing shoes that combines lightweight, resilient midsole foams with rigid moderators and pronounced rocker profiles in the soles. This was a pilot study that explored the use of AFT during training and competition and to describe the injuries sustained in amateur runners.
Methods. This was a retrospective cross-sectional observational pilot study in which 61 amateur runners completed an anonymous questionnaire to determine: demographic characteristics; running activities and injuries sustained using AFT.
Results.The main brands used were Nike (41%), Adidas (12%), Hoka (11%), Sauconi (10%), New Balance (8%), Puma (8%), Brooks (5%), Mizuno (3%), Under Armour (2%). Runners used AFT once a week (67.8%), up to three times a week (27.1%), and 6 times a week (5.1%) less than a year (35%), from 1 to 3 years (50%), and more than 3 years (15%). The 61.7% runners perceived a change in running technique, with greater support on the forefoot (40%), higher activation of calf muscles (36%), different torso position (13.3%), and running instability (10.7%). Onset of delayed muscle soreness appeared after 24 hours training session (62.1%), after 3 months (20.7%), after 1 month (10.3%), and after 1 week (6.9%) the use of AFT. Eight runners (11.8%) reported that they sustained an injury after the use of AFT.
Conclusions. The use of AFT leads to a change perception in running technique amateur runners. Therefore, they should introduce them gradually in their training routine.

Published: February 2024

Apnea, a medical condition characterized by the cessation of breath for more than 15–20 seconds, is a significant health concern affecting an estimated 936 million people globally, with a more significant number being children. In preterm babies, sleep apnea can be a more prevalent issue due to their underdeveloped airways and breathing mechanisms. This condition leaves preterm infants susceptible to complications such as cognitive impairment and cerebral palsy. In Ghana, there is a lack of stand-alone apnea monitoring devices. Given that between 1–5% of children are born with obstructive sleep apnea, the need for such devices is essential. In response to this need, we applied frugal engineering principles to design a user-friendly prototype of an apnea monitor for early detection. The design comprises four central units: a power supply unit, a signal acquisition unit, a processing unit, and a display unit. The system obtains breathing signals from the thoracic region using respiratory and pressure sensors that measure and record the thoracic effort during breathing. These signals are then amplified by an operational amplifier (LM324) and processed by an ATMEGA328p microcontroller programmed using the Arduino IDE. The output is subsequently displayed on a liquid-crystal display (LCD) screen. The device was tested on an adult male with over 90% accuracy in detecting apnea. The outcome indicated the potential of the device to contribute to the early detection and management of apnea, thereby mitigating its associated health risks.

Published: February 2024

We introduce a novel method to aggregate Bipolar Argumentation Frameworks expressing opinions of different parties in debates. We use Bipolar Assumption-based Argumentation (ABA) as an all-encompassing formalism for Bipolar Argumentation under different semantics. By leveraging on recent results on judgement aggregation in Social Choice Theory, we prove several preservation results for relevant properties of Bipolar ABA using quota and oligarchic rules. Specifically, we prove (positive and negative) results about the preservation of conflict-free, closed, admissible, preferred, complete, set-stable, well-founded and ideal extensions in Bipolar ABA, as well as the preservation of acceptability, acyclicity and coherence for individual assumptions. Finally, we illustrate our methodology and results in the context of a case study on opinion aggregation for the treatment of long COVID patients.

Authors: Rafiq Md. Sahil , Khandaker Nadim Reza
Published: February 2024

Findings from the study reveal that Construction and Demolition Waste (CDW) in Bangladesh mainly consists of concrete (56%), brick (15%), mortar (9%), metal (6%), and ceramics (6%). However, the exact constitution may differ depending on the structure and type and structure of building. Additionally, the collective CDW produced in Dhaka, Chittagong, Khulna, Rajshahi, Barisal, and Sylhet totals 3.71 million tons (MT). The WGR of construction and demolition waste is assessed through regression analysis. The mean WGR for Construction and Demolition activities in the fiscal year 2022–2023 are notably recorded at 64.68 kg/m2 and 1626.97 kg/m2, correspondingly for the twelve city corporations of Bangladesh. Unfortunately, a substantial portion of this waste is inadequately disposed of in landfills. The study highlights the potential for entrepreneurial initiatives in recycling materials like concrete, brick, mortar, metal, ceramics, and timber, leading to reduced CO2 emissions and energy consumption. The estimated economic value of recycling concrete, brick and mortar in major cities is approximately 104.5 million USD and 0.45 MT of CO2 reduction from recycling brick and metals from major cities. These findings provide crucial quantitative data for government bodies and industries aiding in developing strategies for CDW management in Bangladesh.

Published: February 2024

Purpose
to evaluate the role of seriated 18-fluoro-2-deoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) in the diagnosis and management of disseminated Mycobacterium chimaera infection following cardiac surgery.
Methods
we retrospectively describe nine consecutive confirmed cases of disseminated M. chimaera infection after cardiac surgery who underwent seriated 18F-FDG PET/CT to facilitate the diagnosis and treatment monitoring. Clinical characteristics, laboratory tests and microbial culture microbiological findings, transthoracic (TTE) and transesophageal (TOE) echocardiography, brain MR and other tests are also discussed.
Results
The mean time between cardiac surgery and symptoms onset was 32 months (range 10 months to 7.7 years). Echocardiography (TTE + TOE ) detected endocarditis (IE) signs in 3/9 patients (sensibility 33%, 6/9 pts having mechanical aortic valve); blood culture was positive in 5/9 patients (sens. 56%). At diagnosis 7/9 PET/CT scans were positive for IE and/or aortic root prosthesis infection (sens. 78%). All diagnostic PET/CT scans were suggestive for systemic infection with hypermetabolism in one or more extracardiac sites (e.g.: lymph nodes, lung, muscle, liver spleen, kidney, CNS, axial skeleton).
Conclusions
18F-FDG PET/CT proved to be a useful tool in diagnosis of disseminated M. chimaera infection to assess the extent and to identify potential sites of biopsy when routine microbiological work-up does not isolate M. chimaera. Seriated scans define the activity of disease over time and contribute to clinical work-up as prolongation or modulation of antimicrobial therapy, prognosis formulation and referral to revision surgery.

Published: February 2024

In the domain of edge computing for medical image analyses, utilizing advanced deep learning algorithms has shown promise in boosting precision and adaptability. Medical image analysis frequently requires striking a compromise between a more comprehensive contextual understanding and specific local information. Even though U-Net with Transformers integration is becoming more and more common, issues like patch flattening and magnification sensitivity still exist. By using a unique approach, U-NeTrans directly addresses these problems by segmenting patches instead of flattening them into tokens. This novel method avoids patch flattening issues while maintaining fine-grained local details. Additionally, U-NeTrans has the benefit of allowing for variable patch sizes in a single architecture, which reduces susceptibility to magnification and supports a range of image resolutions. U-NeTrans demonstrates its effectiveness in improving accuracy in a range of medical image analysis tasks by consistently outperforming its competitors in the thorough examination conducted against publicly available datasets. Notably, using the linear correlation between segmentation accuracy and the divergence in U-NeTrans outputs at various scales, it provides a useful confidence metric for evaluating test image complexity, with values of 98.97\% for Accuracy, 98.81\% for Precision, 99.68\% for Sensitivity, 98.73\% for Specificity, and an AUROC of 99.19\%. In circumstances involving peripheral medical image analysis, when computational performance is crucial, this characteristic is very important.

We developed a targeted next-generation sequencing approach designed for the genomic classification of canine lymphoma. Positioned within the evolving landscape of comparative and veterinary oncology, this study underscores the clinical significance of tailored genetic profiling for this tumor in dogs, marking a crucial step in diagnostic high-throughput genetic analysis.
Leveraging a previous dataset, the “K9 lymphoma assay” demonstrated robust comparability and reproducibility in canine diffuse large B-cell lymphoma (DLBCL), when matched with previously tumors examined through whole-exome sequencing.
Expanding our investigation to encompass several B- and T-cell lymphoma histotypes, we unveiled distinct mutational landscapes distinguishing nodal lymphomas derived from immature lymphocytes and nodal lymphomas originating from mature lymphocytes. TRAF3 was the most frequently altered gene in B-cell lymphomas, exhibiting unique mutational patterns.
Key genetic events, such as TP53 and SETD2 mutations, clinically demonstrated universal implications across B-cell lymphomas, positioning them as potential prognostic and therapeutic indicators.
These findings advocate for a tailored therapeutic approach directly impacting treatment decisions and outcomes in managing canine lymphomas. Our study provides the largest and most comprehensive genomic characterization of clinically staged canine lymphomas to date, and it provides pivotal insights for future research and therapeutic strategies in comparative oncology.

Published: February 2024

Background
Escherichia. coli is the most frequent host for New Delhi metallo-β-lactamase (NDM) which hydrolyzes almost all β-lactams except aztreonam. The worldwide spread of blaNDM-carrying E. coli heavily threatens public health.
Objective
This study aimed to explore the global genomic epidemiology of blaNDM- carrying E. coli isolates, providing information for preventing the dissemination of such strains.
Methods
Global E. coli genomes were downloaded from NCBI database and blaNDM was detected using BLASTP. Per software was used to extract meta information on hosts, resources, collection data, and countries of origin from GenBank. The sequence types (STs) and distribution of antimicrobial resistance gene (ARG) were analyzed by CLC Workbench; Plasmid replicons, serotypes and virulence genes (VFs) were analyzed by submitting the genomes to the websites. Statistical analyses were performed to access the relationships among ARGs and plasmid replicons.
Results
Until March 2023, 1,774 out of 33,055 isolates collected during 2003–2022 were found to contain blaNDM in total. Among them, 15 blaNDM variants were found with blaNDM-5 (74.1%) being most frequent, followed by blaNDM-1 (16.6%) and blaNDM-9 (4.6%). Among the 213 ARGs identified, 27 blaCTX-M and 39 blaTEM variants were found with blaCTX-M-15 (n = 438, 24.7%) and blaTEM-1B (n = 1092, 61.6%) being the most frequent ones, respectively. In addition, 546 (30.8%) plasmids mediated ampC genes, 508 (28.6%) exogenously acquired 16S rRNA methyltransferase encoding genes and 262 (14.8%) mcr were also detected. Among the 232 distinct STs, ST167 (17.2%) were the most prevalent. As for plasmids, more than half of isolates contained IncFII, IncFIB and IncX3. The VF terC, gad, traT and iss as well as the serotypes O101:H9 (n = 231, 13.0%), O8:H9 (n = 115, 6.5%) and O9:H30 (n = 99, 5.6%) were frequently observed.
Conclusions
The study delves into the intricate relationship between plasmid types, virulence factors, and ARGs, which provides valuable insights for clinical treatment and public health interventions, and serves as a critical resource for guiding future research, surveillance, and implementation of effective strategies to address the challenges posed by blaNDM-carrying E. coli. The findings underscore the urgent need for sustained global collaboration, surveillance efforts, and antimicrobial stewardship to mitigate the impact of these highly resistant strains on public health.
The effect of inter-connection properties on the lateral behaviour of moment-frame modular steel structures
Authors: Farajian Mostafa , Khodakarami Mohammad Iman , Kontoni Denise-Penelope N. , Pishgahi Farnoush
Published: February 2024

Recently, there has been a push for the adoption of pre-fabricated modular units in constructing low to high-rise buildings mainly due to the reduction of material waste and construction time. These units are manufactured in a factory and then transported to the construction site for assembly through inter-connections to create a building block. The unique nature of these inter-connections is crucial for the structural performance of modular buildings as they provide modular structure integrity. Despite the growing popularity of modular construction, there is a limited number of published studies examining how inter-connection mechanical characteristics influence the lateral performance of moment-frame modular structures. The stiffness of inter-connections plays a crucial role in determining the overall rigidity of these structures, indicating the importance of studying their impact on the seismic performance of moment-frame modular buildings. The objective of this study is to investigate the impact of inter-connection mechanical characteristics on the lateral performance of moment-frame modular buildings using nonlinear static analysis. For this purpose, three frames with four, eight, and twelve storeys are assumed for analysis. Various inter-connections with different stiffness properties are considered in the nonlinear static analysis. Three performance levels are taken into account, and the responses of the structures at these levels are assessed and compared based on different inter-connection mechanical properties. The findings suggest that a decrease in inter-connections' stiffness results in a reduction of lateral capacity up to around 32.98% for the structural base shear.
Investigating the Mechanical and Physical Enhancements of Silk-sisal Hybrid Composites Through Granite-nano-filler Integration: Synergizing Strength, Damping, and Form
Authors: K Sripriyan
Published: February 2024

This paper focuses on the effect of granite-nano-filler on static mechanical properties, damping behavior, and physical characteristics of silk-sisal hybrid composite. The composites structures are fabricated by using three layers of plain weaves mat with varying weight percentages (2, 4, and 6 wt. %) of granite-nano-filler by hand layer process. The effect of granite-nano-filler on silk-sisal is analyzed and results are compared with pure silk-sisal (without granite-nano-filler) hybrid composite. The results infer that; the tensile strength and flexural strength value of the developed silk-sisal hybrid composites are increased with the increase in wt.% of granite-nano-filler content than pure silk-sisal, approximately 5% and 9% improved value in order by adding 6 wt. % granite-nano-filler on silk-sisal. The tensile and flexural fracture morphology analysis indicated that composed plain weave of silk-sisal fiber mat with two (longitudinal and transverse) directions possesses higher mechanical properties and also observed that, granite-nano-filler dispersed on silk-sisal fiber mat and resin with closely packed. The improved damping factor is obtained by adding 6 wt. % of granite-nano-filler content, which is approximately 75.8% higher than pure silk-sisal. The physical properties of silk-sisal hybrid composite have also been analyzed and well discussed in this paper.

Authors: Nacov Julia , Stemler Jannik , Salmanton-García Jon , Cremer Louise M. , Zeitlinger Markus , Mallon Patrick , Pana Zoi Dorothea , Schmitt Heinz-Josef , Cornely Oliver A.
Published: February 2024

Purpose
Considering the re-emergence of poliomyelitis (PM) in non-endemic regions, it becomes apparent that vaccine preventable diseases can rapidly develop epi- or even pandemic potential. Evaluation of the current vaccination status is required to inform patients, health care providers and policy makers about vaccination gaps.
Methods
Between October 28 2022 and November 23 2022, 5,989 adults from the VACCELEREATE Volunteer Registry completed an electronic case report form on their previous PM vaccine doses including number, types/-valencies and the time of administration based on their vaccination records. A uni-/multivariable regression analysis was performed to assess associations in participant characteristics and immunization status.
Results
Among German volunteers (n = 5,449), complete PM immunization schedule was found in 1,981 (36%) participants. Uncertain immunization, due to unknown previous PM vaccination (n = 313, 6%), number of doses (n = 497, 9%), types/-valencies (n = 1,233, 23%) or incoherent immunization schedule (n = 149, 3%) was found in 40% (n = 2,192). Out of 1,276 (23%) participants who reported an incomplete immunization schedule, 62 (1%) never received any PM vaccine. A total of 5,074 (93%) volunteers reported having been vaccinated at least once and 2,087 (38%) indicated that they received vaccination within the last ten years. Female sex, younger age, as well as availability of first vaccination record were characteristics significantly associated with complete immunization (p < 0.001).
Conclusion
Full PM immunization schedule was low and status frequently classified as uncertain due to lack of details on administered doses. There is an obviousneed for improved recording to enable long-term access to detailed vaccination history in the absence of a centralized immunization register.

Published: February 2024

Highly porous molecularly imprinted polymers (MIPs) with molecular memory have the potential to be used for identifying various compounds. This study investigated the removal of widely used fungicides in agriculture, namely penconazole and carboxin, from aqueous solutions using molecularly imprinted polymerized high internal phase emulsions (MIP-polyHIPEs). The synthesized MIPs were characterized by SEM, TEM, FTIR, BET, and contact angle analyses. The adsorption capacity of MIPs was determined by the UV-Vis analysis. Preliminary studies showed that the MIP-polyHIPEs respectively adsorbed 85% and 57% of penconazole and carboxin. The successful desorption of fungicides from the MIPs indicated its reusability in the adsorption process. The surface hydrophilicity increased by functionalizing the MIP surface with sulfuric acid, leading to a higher adsorption percentage for penconazole. Molecular dynamics (MD) calculations also approved the capability of MIP-PolyHIPEs in adsorbing penconazole and carboxin.

Published: February 2024

Introduction: Obsessive-compulsive disorder (OCD) is a psychiatric condition characterised by persistent, intrusive thoughts and ritualistic behaviours. This study assesses the impact of qEEG-assisted neurofeedback on two critical components of OCD: rumination, a maladaptive focus on problem causes and consequences, and cognitive avoidance (CA), the tendency to evade distressing thoughts aiming to evaluate neurofeedback’s effectiveness in reducing rumination and CA severity in patients with OCD. Methods: This controlled prospective clinical trial with parallel design included patients diagnosed with OCD, with Yale-Brown Obsessive Compulsive Scale (YB-OCS) scores ≥ 16. Subjects were alternately assigned to either the neurofeedback or control groups maintaining a 1:1 ratio. The neurofeedback group underwent 25 sessions over six weeks, with outcomes measured through the Rumination Response Scale (RRS) and the Cognitive Avoidance Questionnaire (CAQ) pre- and post-intervention. Results: Of the initial cohort, 30 participants finished the study. Significant reductions in Rumination and CA were observed in the neurofeedback group with multivariate ANCOVA showing a significant impact on CAQ and RRS scores (Lambda Wilks p = 0.001) and univariate ANCOVA indicating marked decreases in CA (p = 0.001, Eta2 = 0.687) and Rumination (p = 0.001, Eta Squared = 0.636) compared to controls. Discussion: The findings substantiate qEEG-assisted neurofeedback’s role in significantly reducing rumination and cognitive avoidance in OCD, indicating neurofeedback’s potential to modulate brain regions implicated in OCD pathology, such as orbitofrontal cortex and anterior cingulate, thus enhancing self-regulation and reducing symptoms. Limitations: Limitations include no long-term follow-up, reliance on self-report measures, a small, single-centred sample, and convenience sampling, all of which affect the generalizability of the results.

The next step aims to apply three machine learning classifiers and compare their performance to increase the system detection accuracy. These classifiers are Logistic Regression (LR), Random Forest (RF) and Support Vector Machine (SVM). The final step improves the system detection accuracy by applying decision fusion techniques at the classifiers classification result using majority voting algorithm. The accuracy of the proposed model achieved 99.9% by using LTHR-Net as based model and applied majority voting algorithm on the classification output of the three machine learning classifiers.

A number of insects are associated with gut microorganisms, wherein symbionts play pivotal metabolic roles such as nutrient supplementation, diet degradation, and pesticide detoxification. Despite the ecological and evolutionary importance of gut microbial communities in insects, their diversity and dynamics need to be better investigated in many insect species. The green plant bug Apolygus spinolae, a notorious grapevine pest in Japan, damages grape shoots and severely reduces grape berry yield and quality. The plant bug possesses a simple tubular gut housing ~ 104 bacteria. Here we investigated geographic, seasonal, and growth-related dynamics of gut microbiota by high-throughput sequencing in the grapevine pest. In Japanese populations of the plant bug, gut bacterial community was dynamically altered depending on geographic region, season, and developmental stage, in which particularly Serratia, Lactococcus and Caballeronia were abundantly detected. In one vineyard population, Spiroplasma was prevalent. Among the gut bacterial microorganisms, Serratia was consistently and abundantly detected, but significantly affected by seasonal change. In addition, Caballeronia, known as a specific symbiont of stinkbugs, was abundantly detected, especially in insects collected in late summer. The increase of Caballeronia was negatively correlated with Serratia, strongly suggesting an antagonistic interaction between gut bacterial members in A. spinolae.

The Sixth Assessment Report of the Intergovernmental Panel on Climate Change highlights the reliance on optimistic scenarios such as shared socioeconomic pathways SSP1-1.9 and SSP1-2.6 to achieve the 1.5°C or 2°C climate targets by the end of this century[1]. However, these scenarios have not quantitatively assessed the impact of global tensions (measured as global military expenditure as a percentage of GDP) on CO2 emissions. Our research reveals that events such as the 2001–2011 War on Terror and the 2021 prelude to the Russian–Ukrainian war have led to a 0.041% (95% CI: 0.030–0.052) kg/USD increase in CO2 emission intensity (CO2 emissions per unit of GDP) for each 1% rise in global tensions. This increment accounts for 30% of the total change in CO2 emission intensity from 1995 to 2021. In the case of escalating global tensions, with the global military expenditure ratio exceeding thresholds of 11% (for SSP1-1.9) or 23% (for SSP1-2.6), the global surface temperature increase would fail to return below 1.5°C after the initial overshoot in SSP1-1.9, and the 2°C climate target would become unattainable in SSP1-2.6 by the end of this century. These findings underscore the potential of escalating global tensions to undermine climate targets, emphasizing the critical need for a more peaceful international environment to effectively limit global warming to 1.5°C or 2°C.

First proton capture reactions on stored radioactive ions
Authors:   , Dellmann Sophia Florence
Published: February 2024

By combining two unique facilities at the Gesellschaft fuer Schwerionenforschung (GSI), the Fragment Separator (FRS) and the Experimental Storage Ring (ESR), the first direct measurement of a proton capture reaction of stored radioactive isotopes was accomplished. The combination of well-defined ion energy, an ultra-thin internal gas target, and the ability to adjust the beam energy in the storage ring enables precise, energy-differentiated measurements of the (p,gamma) cross sections. The new setup provides a sensitive method for measuring (p,gamma) reactions relevant for nucleosynthesis processes in supernovae, which are among the most violent explosions in the universe and are not yet well understood. The cross sections of the 118Te(p,gamma) and 124Xe(p,gamma) reactions were measured at energies of astrophysical interest. The heavy ions were stored with energies of 6 MeV/nucleon and 7 MeV/nucleon and interacted with a hydrogen gas-jet target. The produced proton-capture products were detected with a double-sided silicon strip detector. The radiative recombination process of the fully stripped ions and electrons from the hydrogen target was used as a luminosity monitor. Additionally, post-processing nucleosynthesis simulations within the NuGrid [1] research platform have been performed. The impact of the new experimental results on the p-process nucleosynthesis around 124Xe and 118Te in a core-collapse supernova was investigated. The successful measurement of the proton capture cross sections of radioactive isotopes rises the motivation to proceed with experiments in lower energy regions. [1] M. Pignatari and F.

Gelingensbedingungen und Herausforderungen der Kooperation von Studierendentandems im Praxissemester
Authors: Lammerding Sandra , Fränkel Silvia , Hanke Petra , Schroeder René
Published: February 2024

Die Kooperation von Lehrkräften verschiedener Lehrämter gilt als wesentliche Voraussetzung für den gelingenden Umgang mit Heterogenität in der Schule. Die Entwicklung kooperativer Kompetenz wird somit zur zentralen Aufgabe der Lehrer:innenbildung. Jedoch fehlt es bisher an einer universitären Verankerung entsprechender Ausbildungsinhalte bzw. -formate. An dieser Stelle setzt das Modellprojekt „Inklusion – Kooperation in (multi)professionellen Teams in der Primarstufe“ an. Studierende des Lehramtes für Grundschulen sowie sonderpädagogi­sche Förderung werden von Lehrenden aus der Grundschul- und Sonderpädagogik auf die Arbeit im Team in inklusiven Lerngruppen in einem gemeinsamen Seminar vorbereitet. An­schließend absolvieren sie ihr Praxissemester im Tandem, um insbesondere Elemente kokon­struktiver Kooperation in der gemeinsamen Planung, Durchführung und Reflexion von Unterricht zu erproben. Ausgangspunkt ist die Frage, wie Studierende die Kooperation im Tandem erleben und für ihren Professionalisierungsprozess nutzen können. Die Ergebnisse aus fünf Interviews mit Studierendentandems (N=10) zeigen ein Erreichen kokonstruktiver Zusammenarbeit als Ergebnis eines non-reflexiven Entwicklungsprozesses trotz einer nicht auf Kooperation aus­gerichteten Schulpraxis.
Abstract
Cooperation between teachers from different teaching professions is considered an essential prerequisite for the successful handling of heterogeneity in schools. Developing cooperative competence is therefore a central element in teacher education, but corresponding academic training content and formats are still rare. The model project "Inclusion - Cooperation in (Multi)professional Teams at the Primary Level" addresses this issue and aims to fill that gap. Pre-service teachers of elementary school and special education are prepared by university lecturers from education sciences and special needs education for teamwork in inclusive learning groups in a joint seminar. They complete their practical semester in tandem, testing elements of co-constructive cooperation in the joint planning, implementation and reflection of lessons. The question is therefore how pre-service teachers experience cooperation in tandems and how they can use it for their professionalization process. Findings from five interviews with pre-service teacher tandems (N=10) indicate a co-constructive cooperation as a result of a non-reflexive development process despite a school practice that is not oriented toward cooperation.
Límites de la ciencia europea, interculturalidad crítica y mundos de la vida en Tierra del Fuego
Authors: Salas Astrain Ricardo
Published: February 2024

La cuestión intercultural del mundo contemporáneo está ligada a la crítica del proyecto moderno de conocimiento y dominio de la naturaleza en cuanto único modo de comprensión de los seres humanos y su entorno. Este predominio casi exclusivo de la ciencia y de la tecnología en el siglo XIX supone un modelo empírico-naturalista y positivista. La metodología se apoya en un análisis hermenéutico de las memorias y los informes científicos de dos expediciones europeas al sur austral de América, a partir de las cuales se critican los tópicos esenciales de una estrecha visión de la ciencia unificada. Los principales resultados de este proyecto asumen la distinción entre las ciencias naturales y las sociales, debatida a partir de la fenomenología y la hermenéutica. Esta crítica permite clarificar la matriz empírico-racionalista que está definida por la expansión de la idea del mundo natural, tal como la determinó la ciencia europea del siglo XIX, la cual degrada y deslegitima los saberes de los mundos y de los pueblos del mar que habitan los confines de la Tierra del Fuego. Se concluye que reexaminar esta noción de ciencia es una cuestión apremiante para la revisión intercultural de las ideas de mundo y de un planeta sustentable.
