Published: October 2024

AbstractHydroforming is a modern metal-forming process prominently used in the shipbuilding, aerospace, and automotive industries for forming lightweight, complex-shaped geometries due to their inherent process benefits. But this process faces challenges such as limited material selection, high tooling costs, and complex process control for obtaining a defect-free part with uniform thickness. Researchers are constantly innovating and advancing hydroforming technologies to overcome these limitations. This work reviews emerging tube and sheet hydroforming technologies, considering parametric effects and design considerations, particularly for micro-domain applications. Further, a wider acceptance of the hydroforming process in different industries is explored by discussing the studies that tried to improve the efficiency and quality of the hydroforming process. This study observed that better formability could be achieved in hydroforming with appropriate intermediate heat treatment, proper lubrication, the correct design of loading paths, and temperature distribution. In tube hydroforming, wrinkles, necking, and cracking observed to be largely reduced by properly selecting the internal pressure and feeding. The precise protrusion height and uniform thickness at different joint cross-sections in tube forming are found to be significantly influenced by the strain-hardening exponent, loading path, and friction coefficient. Electrohydraulic forming is found being increasingly used due to its higher productivity and lower product cost. However, further research is required to achieve complex sheet geometries with sharp corners. This research emphasizes that advanced research, artificial intelligence integration, and the exploration of alternative materials can improve the performance of the hydroforming process.

Abstract
Introduction
Obesity is one of the biggest modern health issues worldwide. Owing to the failure of both behavioral and pharmacological measures, the surgical approach has been established as the main conduct to follow, with bariatric surgery being one of the most effective and safe procedures. One of the bases for the optimal analgesic strategy is the use of adjuvants during the perioperative period. One of the main drugs in use is lidocaine.

Aim
To evaluate postoperative pain after perioperative lidocaine infusion in patients undergoing bariatric surgery and describe the presence of nausea and vomiting during the first 24 h.

Methods
This was a retrospective study of patients who underwent laparoscopic bariatric surgery at ABC Medical Center. Two study arms were established: a group of patients who received lidocaine infusion and a control group. The presence of pain, nausea, or vomiting was evaluated upon admission to the recovery area and 1 h and 24 h after the intervention. The normal distribution of the data was first verified via the Shapiro–Wilk test. The data are presented as medians for quantitative variables and as frequencies for qualitative variables.

Results
A total of 50 surgeries were performed, with a significant correlation between lidocaine infusion and lower pain values at 1 h (p = 0.04). Similarly, there was a marked trend in the presence of nausea in control group 4 (18.6%) vs. 15 (53.5%).

Conclusions
Our data suggest that the use of intraoperative lidocaine infusion is limited in postoperative pain management; nonetheless, it significantly improves the incidence of postoperative nausea.

PURPOSE

Rapidly expanding medical literature challenges oncologists seeking targeted cancer therapies. General-purpose large language models (LLMs) lack domain-specific knowledge, limiting their clinical utility. This study introduces the LLM system Medical Evidence Retrieval and Data Integration for Tailored Healthcare (MEREDITH), designed to support treatment recommendations in precision oncology. Built on
Google's Gemini Pro
LLM, MEREDITH uses
retrieval-augmented generation
and
chain of thought
.

METHODS

We evaluated MEREDITH on 10 publicly available fictional oncology cases with iterative feedback from a molecular tumor board (MTB) at a major German cancer center. Initially limited to
PubMed
-indexed literature (draft system), MEREDITH was enhanced to incorporate clinical studies on drug response within the specific tumor type, trial databases, drug approval status, and oncologic guidelines. The MTB provided a benchmark with manually curated treatment recommendations and assessed the clinical relevance of LLM-generated options (qualitative assessment). We measured semantic cosine similarity between LLM suggestions and clinician responses (quantitative assessment).

RESULTS

MEREDITH identified a broader range of treatment options (median 4) compared with MTB experts (median 2). These options included therapies on the basis of preclinical data and combination treatments, expanding the treatment possibilities for consideration by the MTB. This broader approach was achieved by incorporating a curated medical data set that contextualized molecular targetability. Mirroring the approach MTB experts use to evaluate MTB cases improved the LLM's ability to generate relevant suggestions. This is supported by high concordance between LLM suggestions and expert recommendations (94.7% for the enhanced system) and a significant increase in semantic similarity from the draft to the enhanced system (from 0.71 to 0.76,
P
= .01).

CONCLUSION
Expert feedback and domain-specific data augment LLM performance. Future research should investigate responsible LLM integration into real-world clinical workflows.

Published: October 2024

ABSTRACT
Benthic fish, such as the round goby (Neogobius melanostomus Pallas, 1814) tend to swim near the bottom, especially at increased water velocities. To test whether these fish have a hydraulic advantage from swimming near the bottom and how the substrate affects the forces experienced, we measured the hydraulic forces experienced by preserved fish in a flow channel. The fish were tested 5.0 mm above the bottom at smooth and rough surface, and in the water column (10.0 cm elevation) above smooth and rough surface at 0.95 m/s water velocity. No significant effect among the mean hydraulic forces was observed between both fish positions, whereas the mean hydraulic forces in the water column were significantly higher (P&lt;0.05) above the rough surface (mean 0.077 N±0.025 s.d.) than above the smooth surface (mean 0.068 N±0.021 s.d.). A convolutional neural network (CNN) predicted the column smooth treatment was the most characteristic force data time series (mean F1=0.88±0.03 s.d.). We conclude that the body posture and body movements of the fish are more relevant for the hydraulic forces experienced by the fish than the vertical position in the water column. Further factors explaining the affinity to swimming near the bottom are discussed.

Authors: Anderson Gail , Lawther Lorna 
Published: October 2024

Background/Aims To date, Solihull training for midwives in Northern Ireland has been facilitated as continuing professional development; however, incorporating Solihull Approach Antenatal Foundation Training in undergraduate midwifery education has been recommended. The aim of this pilot study was to evaluate the provision of this training for undergraduate midwifery students. Methods This mixed-method evaluation study used pre- and post-test questionnaires with a purposive sample of 24 final year midwifery students. The data were analysed using descriptive statistics with thematic analysis of free text comments. Results Four themes emerged: perceived benefits in clinical practice; increased knowledge and confidence; increased recognition of the public health role of the midwife; and integration and timing of the training. Conclusions The innovative initiative was positively evaluated and considered an enhancement to current education provision. However, the initiative would have been welcomed earlier in the education programme. Implications for practice Solihull Approach training will be provided at undergraduate level and introduced earlier in the programme, with the subsequent potential to incrementally build on this foundation and include further tiers of training. The impact of students' application of the Solihull Approach in clinical practice warrants further investigation.

HighlightsLoblolly pine and corn stover fiber were successfully surface-treated with epoxy.Surface-treated fibers produced biocomposites with improved tensile properties.Surface treatment process results in a more evenly dispersed fiber bulk structure.Tensile strength and Young’s modulus of the biocomposite reached 58 MPa and 5 GPa, respectively.Abstract. Biocomposites combine renewable, plant-based fibers with degradable polymers and are an attractive option for sustainable, lightweight, and cost-effective materials with a low carbon footprint, especially for large-scale additive manufacturing. One of the major challenges in the widespread adoption of biocomposites is that their mechanical performance is significantly inferior to that of synthetic composites. Surface treatment is a common and effective technique to improve the mechanical properties of the biofibers used in biocomposites. This study aims to investigate the physical and flow properties of surface-treated biofibers, as well as the tensile properties of their PLA-based biocomposite, to gain insights into how surface treatment changes the fiber’s characteristics and biocomposite’s mechanical properties. Surface treatment was created using a two-component epoxy system by reacting poly(bisphenol A-co-epichlorohydrin) glycidyl end-capped (PBG) and dicyandiamide (DICY). The treatment was tested on two different biofibers (loblolly pine and corn stover fibers) with three different PBG/DICY molar ratios (0.25, 0.5, and 2). Results showed that surface-treated fibers improved the tensile strength and Young’s modulus of the biocomposites. Loblolly pine biocomposites from fibers treated with a PBG/DICY ratio of 0.25 exhibited the best tensile properties. The surface treatment resulted in a more loosely dispersed fiber bulk structure, as evidenced by less fiber agglomeration into smaller particle sizes, higher fiber sphericity, and lower loose bulk density. This can enhance stress distribution and the overall mechanical performance of the biocomposites. Additionally, surface-treated fibers exhibited better dynamic flow properties.

Published: October 2024

Flower is an important part of the plant containing phytochemical compounds, especially the phenolic acids, flavonoids, and anthocyanin that can be used as natural antioxidants. Phytochemical compounds are usually drawn by steeping the flower petals in hot water. Indeed, different temperatures and steeping times would affect the yield of phytochemicals obtained. The butterfly pea flower is one of edible flowers that brings antioxidant activity due to the presence of phytochemical compounds, namely flavonoids and phenolic acids. Nevertheless, there have been limited studies dedicated to the search of steeping condition of butterfly pea flower petals in water. Thus, this study aimed to determine the time and temperature of steeping to produce the butterfly pea step with preferred physicochemical characteristics. The result indicates that butterfly pea flower petals which undergo steeping at 60°C for 45 minutes produce antioxidant activity with an IC50 value of 251.89 ± 32.02 ppm. Furthermore, the butterfly pea flower steep produced had blue to purple color with °Hue of 277.06 ±2.55, 1.23 ± 0.07 mg/L of total monomeric anthocyanin content, 6.83 ± 0.02 of pH and 138.42 ± 15.88 mg GAE / g sample of total phenolic content.

Published: October 2024

Abstract
The purpose of the present work is to determine the neutronic characteristics of annular cylindrical prismatic Very High Temperature Gas-cooled Reactor (VHTR) with different advanced fuel designs. The study includes detailed neutronic investigations of the eight types of TRISO (containing SiC layer) and TRIZO (containing ZrC layer) fuel particles for annular VHTR core. All calculations were performed using continuous energy Monte Carlo code MVP2.0 and MVPBURN with JENDL4.0 nuclear data library. The obtained results indicated that SiC + PyC and PyC layers in TRISO fuel appeared to be not excellent choice for the annular VHTR core due to its shorter operation year and, lower fuel burnup. The annular cylindrical prismatic core fueled with TRIZO fuel particle shows good neutronic characteristics compared to those designed with other TRISO fuel particles.

We aim to apply this theory to many structures and obtain Dirichlet eigenvalues for problem applications. Some new results regarding the vanishing mean curvature are presented as a partial solution, and this can be considered for the well-known problem given by Chern.

Published: October 2024

Abstract
Non-Hermitian systems can be tuned to exhibit exceptional points, where both eigenvalues and eigenstates coalesce concurrently. The inherent adaptability of photonic non-Hermitian systems in configuring gain and loss has allowed us to observe a plethora of counterintuitive phenomena, largely as a consequence of the eigenspace reduction at these exceptional points. In this work, we propose a non-Hermitian metasurface that, through the incorporation of gain, enables complete asymmetric polarization conversion at an exceptional point with a zero eigenvalue. Specifically, we provide numerical evidence for this concept by designing a non-Hermitian metasurface that facilitates polarization conversion from right to left circular polarization, while preventing conversion in the reverse direction and co-polarized transmission. Furthermore, our investigation reveals that this specific form of complete asymmetric polarization conversion results in maximum circular dichroism in transmission, thereby eliminating the need for external chirality or three-dimensional helical structures. This non-Hermitian technique offers an intriguing approach to designing polarization-sensitive optical devices and systems, further expanding their functionalities and capabilities.
Transverse optical torque from the magnetic spin angular momentum

Published: October 2024

Abstract
We report a transverse optical torque exerted on a conventional isotropic spherical particle in a direction perpendicular to that of the illuminating wave propagation. By using full-wave simulations and deriving an analytical expression of the transverse optical torque for particle of arbitrary size, the origin of this transverse optical torque is traced exclusively to the magnetic part of the spin angular momentum, regardless of the size and composition of the illuminated particle. To our surprise, for a non-magnetic dielectric particle, the transverse optical torque is found to originate mainly from the magnetic response of the particle, even when the particle size is much smaller than the illuminating wavelength. This is contrary to the general intuition that the electric response of a non-magnetic dielectric particle dominates its magnetic response in the mechanical effect of light, especially in the Rayleigh limit.

Abstract
Schiff bases have proven to be beneficial in medicine and have interesting complexation capabilities with transition metals. The +4, +5, and +6 oxidation states of schiff base metal complexes have been the subject of recent review, which have highlighted their notable cytotoxic effects against various colon cancer cell lines (HT-29, HCT-116, SW-480, Coco-2, CT-26, LT-174, LoVo). Extensive research has focused on schiff base metal complexes in the +4 and +6 oxidation states, exhibiting distinct geometries and significant thermodynamic stability. These studies provide IC50 values for these complexes in colon cancer cell lines along with comprehensive structural representations that shed light on how different substituents affect cytotoxicity. When compared to schiff base ligands alone, metal complexes of schiff bases have been shown to significantly reduce colon cancer cell invasion and proliferation. The studied literature emphasizes schiff base metal complexe’s potential in biological applications and suggests that more study may be necessary to fully comprehend their biology. To enable more sophisticated multidisciplinary study in this field, future investigations should focus on synthesizing novel complexes with enhanced bioavailability, solubility, and low toxicity.
