The integration of Large Language Models (LLMs) into microservice-based systems introduces new resilience challenges due to unpredictable latency, probabilistic outputs, rate limits, and external dependency failures.Traditional fault-tolerance mechanisms are insufficient to address the non-deterministic and resource-intensive nature of LLMbased services.This paper presents a resilience-driven architectural approach for integrating LLMs into microservices using circuit breakers, adaptive timeouts, and intelligent fallback strategies.The proposed design extends classical resilience patterns by incorporating LLM-aware failure detection, response degradation policies, and context-preserving fallbacks such as cached responses, lightweight models, or rulebased services.We analyze failure modes unique to LLM inference, including prompt amplification, cascading retries, and semantic degradation under partial failures.A reference architecture is proposed and evaluated through simulated workloads, demonstrating improved system availability, reduced tail latency, and controlled cost escalation under failure conditions.The results show that resilience-aware LLM integration is essential for production-grade, enterprise-scale microservices and provides a foundation for reliable AI-assisted distributed systems.

Predation exerts strong selection pressure on morphological traits and is often studied in freshwater fishes. A common morphological ecophenotype driven by predation from pursuit predators is the predator-associated burst speed (PABS) ecophenotype. This ecophenotype, characterized by a smaller head, smaller body, and larger caudal region, is commonly found in western mosquitofish (Gambusia affinis) residing in environments with sunfish (family Centrarchidae) predators. However, the repeatability and transferability of the PABS ecophenotype across populations have not been tested. The four objectives of this study were to (1) assess the repeatability of methods to confirm the presence of the PABS ecophenotype in independent populations, (2) test whether morphology is correlated with predator abundance, (3) assess the repeatability of utilizing a discriminant function analysis (DFA) to accurately classify fish to predator status, and (4) use a DFA to conduct a cross-validation test of the PABS model using previously studied populations of G. affinis to predict predator status of newly studied populations. There was consistency in the occurrence of the PABS ecophenotype among populations with predators. Permuted MANOVA (PMANOVA) models fit to each dataset revealed a significant effect of collection site nested within predator status (i.e., presence or absence of predator), suggesting location-specific variations of the PABS ecophenotype. In addition, a PMANOVA model fit to body shape as a function of predator abundance (i.e., 0, 0.1-1.0, or >1.0 predators per minute of electrofishing) revealed a significant effect of predation level in the newly studied populations, suggesting morphology differs among populations with varying predator abundances. Cross-study validation of the DFA revealed low between-study accuracy compared to within-study accuracy, but elongation of the caudal region in the presence of predators was consistent across studies. Our findings ultimately suggest that although the PABS ecophenotype at studied locations provides partial predictive capacity at unstudied locations, the nature and magnitude of the PABS ecophenotype depend on environmental settings, encounter histories with predators, level of abundance of predators, or other spatially structured mechanisms.

During the COVID-19 pandemic, acute care nurse managers functioned in a critical role by helping to advance the mission and goals of their organization while navigating a rapidly evolving healthcare landscape. This resulted in high levels of ongoing job-related stress which is linked to negative physical, psychological, and job-related outcomes. Little is known about the perceptions regarding their own professional well-being during this time. The aim of this study was to qualitatively describe acute care nurse managers' perceptions of and barriers to their professional well-being. Using a qualitative descriptive approach, nurse managers from a hospital system in the southwestern United States responded to two short-answer, survey-based questions in 2022: (1) "Describe the definition of nurse-manager well-being in your own words" and (2) "What do you feel is your biggest barrier to professional well-being?" Reflexive thematic analysis was utilized to analyze participant responses (N = 80). Professional well-being is a complex concept influenced by the nurse manager's ability to navigate work-life balance; care for their own physical, emotional, and spiritual selves; give and receive support from stakeholders; and manage feelings of thriving vs. struggling in the role. Barriers most cited as influencing well-being included having too little time to get things done coupled with increasing workloads, feeling stuck in the middle among stakeholders, and coping with ongoing staffing challenges. The definition of and barriers to well-being are influenced by the specific needs and experiences of the nurse manager. While not all barriers can be immediately removed, the identification of individual and organization-specific barriers needs to be taken seriously, reviewed by those who can promote change, and evidence-based solutions for improvement piloted or implemented when feasible.

The rapid evolution of cloud-native computing has compelled enterprises to migrate from legacy Platform-as-a-Service (PaaS) environments such as Pivotal Cloud Foundry (PCF) toward Kubernetes-native solutions like Red Hat OpenShift.While both platforms deliver automation, scalability, and operational consistency, the architectural disparity between PCF's Warden container model and OpenShift's Kubernetes orchestration introduces complex challenges in migration, particularly concerning security, compliance, and workload resilience.This paper proposes a Security-Aware Migration Framework (SAMF) that enables seamless and compliant transition of enterprise workloads between heterogeneous PaaS environments.The proposed framework integrates automated security policy mapping, container equivalence validation, and DevSecOps-driven CI/CD reconfiguration to preserve both operational integrity and compliance posture during migration.Empirical evaluation using real-world financial and telecom case studies demonstrates up to 42% reduction in migration-induced downtime, 30% improvement in policy enforcement accuracy, and Sireesha Devalla https://iaeme.com/Home/

The weight of gas formed by Li-ion cell components heated to 400°C was studied by DSC. Electrolyte released the most gas – over 70% of its original weight during the heat treatment, while fully charged cathode and anode released gas at 4.6% and 3.9% of their original weight, respectively. Thus, the weight of gas formed during heat treatment by various solvents, LiPF6, and electrolytes containing various solvents or lithium salts was studied. Solvent thermal stability was the key to reducing the gas formation of electrolyte at elevated temperature. Electrolyte containing g-butyrolactone (GBL) solvent delayed the venting of Li-ion cells by approximately 50 °C compared with conventional electrolyte containing carbonate solvents during a hot box test. Cell venting was observed to be due to gas pressure from electrolyte decomposition in the cell.

Three types of fluorinated carbon, all in their original form and upon sequential chemical lithiations via -butyllithium, were investigated by and solid-state NMR methods. The three starting materials [where (nominally)] were fiber based, graphite based, and petroleum coke based. The aim of the current study was to identify, at the atomic/molecular structural level, factors that might account for differences in electrochemical performance among the different kinds of . Differences were noted in the covalent F character among the starting compounds and in the details of LiF production among the lithiated samples.

Structural studies have been carried out on (silver vanadium oxide, SVO) and , lithiated SVO with , 2.13, and 5.59 using nuclear magnetic resonance (NMR) and X-ray absorption spectroscopy (XAS). Lithium-7 NMR indicates the formation of a solid electrolyte interphase layer on the sample and lithium intercalation into both octahedral and tetrahedral sites in the SVO lattice, and that most but not all of the Ag (I) is reduced prior to initiation of V(V) reduction. Vanadium-51 NMR studies of SVO and lithiated SVO show decreased crystallinity with increased lithiation, as previously reported. Silver XAS studies indicate the formation of metallic silver crystallites in all the lithiated samples. A comparison of X-ray absorption near edge spectroscopy spectra for vanadium in these samples with those of reference compounds shows that some reduction of vanadium (V) occurs in the lithiated SVO with and increases with further lithiation leading to the formation of V(IV) and V(III) species. The results of this study indicate that vanadium(V) reduction occurs in parallel with silver (I) reduction during the initial stages of SVO lithiation, leading ultimately to the formation of vanadium (IV) and (III) species with further lithiation.
