Influence of scintillation light confinement on depth-of-interaction measurement performance in a single-ended readout PET detector
Continuous depth-of-interaction (cDOI) detectors enable single-ended readout in positron emission tomography (PET) by encoding the interaction depth into the scintillation light distribution. This study presents a comprehensive performance optimization of a cDOI detector based on light distribution tailoring with crossed triangular-shaped reflectors by analyzing the effects of optical geometry based on various DOI decoding algorithms. Two parameters were systematically varied: the degree of ligh

Quantized Conductance through Surface States in High Quality Three-Dimensional Dirac Semimetal Cd3As2 Nanowire/Nanoribbon p-n Junctions
We report the observation of quantized conductance in high-mobility three-dimensional Dirac semimetal Cd3As2 nanowire and nanoribbon p-n junctions. By employing suspended device geometries with dual local gates, we form tunable p-n junctions and realize ballistic transport across sub-micron channel lengths. In a wide nanoribbon device with a channel width of similar to 330 nm, conductance plateaus appear at integer multiples of 2e(2)/h in the n-n regime under high magnetic fields. Numerical simu

Rapid detection of airborne fungal contamination using a molecularly imprinted polymer approach for ergosterol
Fungi are major biological contaminants in indoor air, and their concentration is typically assessed using the culture-based CFU method, which is labor-intensive and time-consuming. Ergosterol, a major fungal cell membrane component, has emerged as a preferred target for alternative analytical approaches. However, ergosterol is highly hydrophobic, and specific affinity probes such as antibodies or aptamers have not yet been successfully developed. In this study, we fabricated ergosterol-specific

Life cycle assessment of a novel porous solid-state electrolyte reactor: Acetic acid as a case study
Utilizing captured waste carbon dioxide (CO2) emissions as feedstocks to carbon monoxide (CO) electrolyzers is a promising technology to produce valuable chemical products at an industrially relevant scale. The chemical industry is currently operated by industrial processes that are heavily reliant on fossil-based feedstocks making it a hard to decarbonize industry but also simultaneously making it an industry that is ideal for captured carbon valorization. Through the use of a CO reduction reac

Signal Processing Design for Cochlear Implant System Using Piezoelectric Sensor
Today, the cochlear implant system is the most successful auditory prosthesis for the patients suffering hair cell loss or damage. The current cochlear implant system consists of an implantable electrode array for the stimulation and an external signal processor includ-ing a microphone and a battery. However, the conventional cochlear implant system is composed of a heavy signal processor. Furthermore, the exposure of an external signal processor causes a cosmetic problem to the patients. Theref

Edge-Server Workload Characterization in Vehicular Computation Offloading: Semantics and Empirical Analysis
Edge server-assisted computation offloading enables vehicles to leverage server compute resources to deliver connected services, overcoming the limitations of onboard resources. Understanding the compute workloads of edge servers is crucial for effective resource management and scheduling, yet this task is challenging due to the complex interplay of factors such as vehicle mobility and computation offloading patterns. To address this, we propose an empirical analysis framework that systematicall
