Manual cocoa bean inspection is subjective and prone to error, significantly impacting chocolate production. This study presents an automated, high-throughput cocoa bean grading system leveraging YOLOv10, YOLOv11, and Vi...

Study objective: To evaluate whether impaired ventriculo-aretrial interaction characterizes chronic ischemic heart disease (CIHD) caused by stable chronic obstructive coronary artery disease (CAD), using wave intensity a...

"Modifying neural activity is a substantial goal in neuroscience that facilitates the understanding of brain functions and the development of medical therapies. Neurobiological models play an essential role, contributing...

Copper sites in proteins are designed to perform either electron transfer or redox catalysis. Type 1 and CuA sites are electron transfer hubs bound to a rigid protein fold that prevents binding of exogenous ligands and s...

"This article reports the ongoing work on an environment for hardware-in-the-loop (HIL) and software-in-the-loop (SIL) tests of CubeSats and the benefits gained from using such an environment for low-cost satellite devel...

Neurotransmitter receptors of the Cys-loop superfamily mediate rapid synaptic transmission throughout the nervous system, and include receptors activated by ACh, GABA, glycine and serotonin. They are involved in physiolo...

In this paper we study the effective lepton flavor violating vertex of an electroweak Z gauge boson and two charged leptons with different flavor, lk and lm, that is generated to one-loop in low scale seesaw models with ...

"This work presents a multi-unmanned aerial vehicle formation implementing a trajectory-following controller based on the clusterspace robot coordination method. The controller is augmented with a feed-forward input from...

Abstract Cell differentiation is a complex process characterized by specific gene expression patterns regulated through enhancer-promoter interactions within the three-dimensional architecture of the nucleus. The precise...

Abstract The combination of optical fiber and phototheranostic agents has emerged as a promising strategy to address the challenges of limited light penetration depth and systemic toxicity of nanomaterials. However, the ...

Abstract This work presents four systems for generation of optical subcarriers in the C-band in optical communications, based on serial and parallel amplified optical ring resonator with phase modulation and 10 GHz spect...

BackgroundSystemic sclerosis (SSc) is characterized by a complex and heterogeneous interplay between vascular dysfunction, immune activation, and progressive fibrosis. Despite advances in molecular characterization, ther...

Introduction. The stability of grid-connected inverters is critical for the integration of renewable energy into modern power systems. However, this stability is significantly challenged under weak grid conditions, chara...

A novel modular positive-sequence estimation algorithm for phasor measurement units (PMUs) is described in this paper with a focus on the restrictions imposed by the IEEE C37.118.1-2011 standard. The first stage consists...

Integration of Photovoltaic (PV) generation into oil and gas power networks has transformed fault behaviour by creating highly complex sensitivity challenges for conventional Overcurrent Relay (OCR) coordination and trip...

Digital Twin Networks (DTNs) are emerging as a key enabler for the robust optimization and lifecycle management of next-generation networks. However, current DTN approaches still rely heavily on manual design, implementa...

Abstract Due to the complex structures of multi-limbed parallel robots, conventional parallel robots generally have limited workspace, complex kinematics, and complex dynamics, which increases the application difficulty ...

The laminar shear box is the most commonly used soil container in shaking table tests for soil-structure dynamic interaction. On the basis of the development experience of the worldwide shear boxes, the two-dimensional l...

Communication delays within connected and autonomous vehicles (CAVs) pose significant risks. It is imperative to address these issues to ensure the safe and effective operation of CAVs. However, the exploration of commun...

This work presents the workflow and supporting tools used to realize a 500 kW, ±10 kVdc MMC-based laboratory supply. Control Real-Time Hardware-in-the-Loop (RT-CHIL) simulations have played a key role in its devel...

Ileosigmoid knotting (ISK) is a rare, life-threatening condition often difficult to diagnose radiologically. We report a 55-year-old male presenting with acute abdominal pain. While CECT suggested a closed-loop obstructi...

Triterpene saponins (TS) are a structurally diverse group of metabolites that are widely distributed in plants. They primarily serve as defense compounds and their production is often triggered by biotic stresses through...

Abstract Introduction Evoked compound action potentials (ECAPs) are neurophysiological biomarkers of neural activation during spinal cord stimulation (SCS). Clear distinction between ECAPs and nonphysiological signals is...

Flat-band systems have attracted considerable interest in different branches of physics in the past decades, providing a flexible platform for studying fundamental phenomena associated with completely dispersionless band...
