Abstract Sandwich panels with truss cores (SPTCs) are widely used in crashworthiness and impact-related applications due to their light weight, high load-carrying capacity, and excellent energy dissipation performance. However, most existing design optimization methods for SPTCs are limited to size and shape optimization of the truss bars and often focus solely on linear elastic behavior. In this study, a topology optimization framework to design the core of SPTCs is proposed using the geometry projection method, aiming to maximize plastic energy absorption and minimize deflection under quasi-static loading, while constraining material usage. An elasto-plastic constitutive model is employed to capture the nonlinear material behavior, and an element removal strategy is used to avoid severe mesh distortion and ensure a robust analysis. Design sensitivities are computed using a finite difference scheme, leveraging the relatively low number of design variables describing the bars and circumventing the need for analytical derivatives. The proposed approach is demonstrated through numerical examples, with the optimized designs evaluated against conventional pyramidal truss-core panels. The results confirm the practical applicability and effectiveness of the method for designing protective structures.

Purpose: ButyraGen ® (Registered Trademark of NutriScience Innovations, LLC), generates butyrate, a short-chain fatty acid, in the small intestine without the drawbacks of conventional formulations. Butyrate has roles in metabolism, immunity, and inflammation, and has emerging relevance in gut-brain axis signaling and psychological health. This randomized, double-blind, placebo-controlled trial evaluated ButyraGen’s effects on mood and well-being. Patients and Methods: A starting cohort of 596 adults were randomized and double-blinded to receive 200 mg/day of ButyraGen or placebo for six weeks in a fully virtual study. Validated questionnaires were administered to assess changes in anxiety, depression, and functional outcomes. Analyses followed an Intent-to-Treat protocol, with Minimal Clinically Important Difference (MCID) used to identify meaningful improvements through post-hoc analyses. Results: ButyraGen significantly reduced self-reported anxiety in men, who were over twice as likely to achieve clinically meaningful improvement versus placebo. Across all participants, improvements in feelings of fear and unease were observed. No overall benefit for self-reported depression was seen, but participants without gastrointestinal disease had a twofold greater likelihood of improvement compared to placebo. Further analysis showed improvements in hopelessness and helplessness among younger adults and men. Functional improvements were also seen for reduced distraction and improved social engagement. Conclusion: These results suggest that ButyraGen may supports both psychological and physiological well-being, particularly in men, younger individuals, and those without gastrointestinal disease. Benefits began to appear within weeks two and three and were sustained through six weeks, highlighting its potential as a fast-acting intervention for both gut and brain health, indicative of the gut-brain axis connection.

The proposed research starts a Federated type Learning framework for risk diagnosis in enterprise information security model, aiming to improve threat detection and decision-making Potential without compromising information privacy. In contrast to traditional centralized type schema, this outline which allows several enterprises to a collectively trained system it maintains the confidentiality data of their respective local data's. The newly designed model has the federated type learning schema to integrate those trained locally into a data privacy risk assessment framework, for assuring adaptable learning from several organizational contexts. By merging of supervised learning schema able of adaptive type learning, anomaly identification process, and predictive manner of analysis, the framework shows a deeper mechanism to detection ca0abilities potential risks, information prioritize usage, and its strengthen overall security posture. The main advantage of this framework is that it can preserve data confidentiality and at the same time benefit from collectively type of intelligence, for allowing models to take advantage of shared information without compromising any of data privacy. Moreover, the proposed system also highlights advantage in the methodology of federated type coordination, model optimization, and for smart Data aggregation, thus going beyond data reliability, scalability, and related usage of enterprise-level data risk assessment.

Abrasive Waterjet cutting technology is more environmentally friendly than other methods like plasma and laser cutting. As a cold cutting method, it does not use flammable gases. Furthermore, it uses water and natural garnet as abrasive materials. The amount of waste is significantly lower compared to other methods. This study aims to increase cutting speed and efficiency while lowering carbon emissions by controlling the taper angle and enhancing machine sensitivity. The primary objective of this study was to optimize errors caused by the kerf and the taper angle in a waterjet cutting machine, both mechanically and during the cutting process. The goal of increasing precision was achieved successfully. A 10 mm thick SS314 Steel was processed using a CNC waterjet cutting device. Mechanical compensation was performed using a laser-based algorithm that measured and compensated for values at 10 mm intervals along the X and Y axes. After determining the waterjet's taper angle, the 5-axis cutting head was aligned perpendicular to the edge to ensure accuracy. The most efficient cutting parameters were found to be a pressure of 3.750 bar, an abrasive flow rate of 0.4 kg/m, a 1.02 mm nozzle, a 0.35 mm orifice, and 80 mesh garnet abrasive. The cutting speed was set at 300 mm/min. The taper angle was 1 degree, and the 5-axis machining head was positioned perpendicularly to the material's edge. Cutting was performed by tilting the head by 1 degree to effectively eliminate the taper angle effect. Design FMEA, as defined by the FMEA Tables of the IATF 16949 Automotive Standard, is typically used to identify the most critical characteristics. The patent for this original study is registered with the Patent Office (Patent no: TR 2018 20101). The improvements in cutting angle and precision have increased machine efficiency, which in turn has led to higher cutting speeds and reduced carbon emissions. By controlling the cutting angle, a thinner kerf is created, which leads to a reduction in waste.

The purpose of this presentation is to aid bovine practitioners and clinic owners in expanding their practice to include small ruminant clients as well as how to service them to keep them as returning and valued clients. We will review what makes small ruminant clientele as well as the animals themselves, different to cattle clients and patients.

Climate-sensitive extreme weather events are increasingly impacting frontline clinic operations. We conducted a national, cross-sectional survey of 284 self-identified administrators and other staff at frontline clinics determining their attitudes toward climate change and the impacts, resilience, and preparedness of clinics for extreme weather events. Most respondents (80.2%) reported that humans are causing climate change, and nearly half (45.9%) reported concerns about extreme weather impacting their job, with barriers to preparedness including financing and knowledge and resources. Over a third (41.8%) of respondents reported taking steps to protect their clinic infrastructure from extreme weather, including by addressing power and improving ventilation.
