A quantitative evaluation method for nonlinear elastic characteristics of piezoelectric materials in high-power operation using constant current (CC) measurements was established. The admittance curves obtained from conventional constant voltage measurements are unsuitable for curve fitting to determine the nonlinear coefficients, due to the hysteresis and jump phenomena in the admittance curve. T
The ability to precisely control the localization of individual cells or other microscopic biological particles in aqueous suspension inside a microfluidic confinement is essential for the realization of future tools for single-cell studies in basic biology and medicine. We previously demonstrated that thermoacoustic streaming stemming from interactions of an acoustic field with a thermal gradient
Den ökande åldern hos brobestånden världen över kräver en systematisk utvärderingav deras säkerhet och en uppskattning av deras återstående livslängd. Samtidigtmedför strävan efter hållbarhet och kostnadseffektivitet att infrastrukturförvaltarebehöver förlänga användningen av befintliga konstruktioner och därigenom minskautsläppen av växthusgaser samt optimera användningen av ekonomiska resurser.FThe growing age of bridge inventories worldwide demands a systematic evaluation of their safety and estimation of their remaining service life. At the same time, the pursuit of sustainability and cost efficiency compels infrastructure managers to prolong the use of existing structures, thereby reducing greenhouse gas emissions and optimising financial resources. To achieve these objectives, assess
Multipliers are key components in compute-intensive applications but incur high hardware cost. In error-tolerant domains such as image processing, approximate computing enables significant efficiency gains. This work presents a scalable approximate multiplier based on a deterministic, priority-driven partial product removal algorithm. The method assesses an extensive design-space exploration and a
Objectives: This study aimed to explore the stakeholder perspectives in a public–private partnership project as a remarkable initiative to enhance quality education at the tertiary level in Turkey. In this regard, the motivations behind participating in the partnership, perceived benefits and challenges, significant outcomes, and recommendations for similar prospective partnership programs were in
This study examines sustainable practices in the child immunisation vaccine supply chain (VSC) in Uttar Pradesh, India, to support the UN’s Sustainable Development Goals (SDGs). This analysis examines the impact of social, economic, and environmental sustainability practices on the VSC’s efficacy and efficiency, as well as their contribution to achieving SDG goals, including improved healthcare ac
α -Ga2O3 is one of the ultra-wide bandgap semiconductors that gives promise to the development of next-generation power electronics. However, due to its thermodynamic instability and low thermal conductivity, overheating concerns hinder the deployment of α -Ga2O3 devices. This study reveals the detrimental impact of thermal crosstalk in multi-finger α -Ga2O3 MOSFETs. The thermal conductivity of α
Aluminum Gallium Nitride (AlxGa1−xN) is an ultra-wide bandgap alloy popularly used in microwave and radio frequency power amplifier applications. Other uses include light emitting diodes, lasers, and photodiodes. The bandwidth of AlxGa1−xN in such applications can be tailored from 3.2 eV to 6.2 eV depending on the application needs by changing the Al fraction, x. As in most current semiconductor d
Blood plasma separation is a fundamental step in point-of-care diagnostics and testing. However, conventional centrifugation relies on bulky equipment and multiple manual handling, while most microfluidic methods struggle to achieve high purity, high throughput, and high plasma yield simultaneously. In this study, we demonstrate a high-performance acoustofluidic plasma separation device satisfying
In this work, an optimisation algorithm is employed to calibrate a quasi-brittle phase-field cohesive zone model against notched three-point bending experiments on bovine cortical bone using the force vs crack mouth opening displacement data. Calibration is performed both for individual specimens, to quantify parameter variability, and for groups of specimens from the same subject and crack propag
Voltage instability imposes hard limits on transmission capacity in many power systems, constraining both real-time operation and ex-ante capacity allocations. This paper proposes a system integrity protection scheme (SIPS) based on VSC-HVDC links in hybrid AC/DC power systems, designed to maximise loadability under stressed conditions and thereby increase secure transmission capacity. The core co
This entry provides an analytical account of the Convention on the Rights of Persons with Disabilities (CRPD), examining its emergence from the failure to realise universal human rights for persons with disabilities and the participation of organisations of persons with disabilities in its negotiation. It examines the Convention’s origins, the breadth and structure of its rights, its understanding
Salmonella enterica can persist asymptomatically within tissues for extended periods. This is achieved through intricate host–pathogen interactions in immune cell aggregates called granulomas, wherein Salmonella establish favourable cellular niches to exploit while the host limits its expansion and tissue dissemination. Here, using a mouse model of persistent Salmonella infection, we identify a ho
Salmonella enterica is one of the most widespread bacterial pathogens found worldwide, resulting in approximately 100 million infections and over 200 000 deaths per year. Salmonella isolates, termed ‘serovars’, can largely be classified as either nontyphoidal or typhoidal Salmonella, which differ in regard to disease manifestation and host tropism. Nontyphoidal Salmonella causes gastroenteritis in
Salmonella enterica serovar Typhimurium must adapt to rapid environmental shifts, including those encountered upon entry and during replication to survive within macrophages during pathogenesis. Despite extensive RNA-seq-based investigations, questions remain regarding the range, timing and magnitude of response dynamics. Here we constructed a comprehensive GFP-reporter strain library representing
