The need to know the dose of X-rays to be applied to patients suffering diseases such as cancerrequires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimetershas yielded excellent results ...

Analytical solutions based on the pseudo-steady state approximation (PSSA) were derived for the case of controlled dispersed-drug release from erodible and non-erodible planar matrices, through a membrane, and taking int...

We demonstrate the formation of the near field with non-trivial phase distribution using surface plasmon interference devices, and experimental quantitative imaging of that phase with near-field phase microscopy. The pha...

Abstract We establish an intuitive connection between transformation optics (TO) and the classical invariants of étendue and radiance. Through explicit application of the optical-metric formulation of TO, we demonstrate...

This article presents the design and experimental validation of a 25-kW bidirectional DC/DC converter employing a dual DAB-CLLC resonant architecture to achieve high efficiency across an ultrawide 200–1000-V opera...

Abstract The rising complexity of urban areas, along with growing public safety needs, has made intelligent video surveillance systems more essential. The current surveillance systems that rely on human observation and p...

In this review, we focus on the experimental demonstration of enhanced emission from single plasmonic tunneling junctions consisting of coupled nano antennas or noble metal tips on metallic substrates in scanning tunneli...

Abstract The Boltzmann transport equation is the basic equation for solving the transport of charge carrier (electrons, holes) problems in semiconductor devices. The distribution function has been obtained from the solut...

This study investigates the blood-based peristaltic flow of magnetite nanoparticles influenced by temperature-dependent electrical conductivity and the Hall current. The analysis of thermal transmission takes into accoun...

Abstract Cavities provide a means to manipulate the optical and electronic responses of quantum materials by selectively enhancing light-matter interaction at specific frequencies and momenta. While cavities typically in...

Abstract The use of animal-borne devices to measure acceleration has yielded insights into animal locomotion, behaviour and energy expenditure. We present the first systematic review of accelerometry on animals, spanning...

Wave propagation in time-varying media enables unique control of energy transport by breaking energy conservation through temporal modulation. Among the resulting phenomena, temporal disorder – random fluctuations in m...

Deciding on approving and granting market access to new medical technologies such as pharmaceutical products, vaccines, or medical devices is a multifactorial research problem. Balancing out clinical performance, epidemi...

Abstract Precision grinding is a key process for realizing the use of large-aperture aspherical optical elements in laser nuclear fusion devices, large-aperture astronomical telescopes, and high-resolution space cameras....
