Ultimate Intrinsic SNR Depends on B0 Orientation

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This work aims to investigate the effect of B0$$ {B}_0 $$ orientation on the uiSNR in MRI. Methods Electromagnetic simulations were performed on both realistic body models and simplified geometric models. Comparisons between (1) opposite B0$$ {B}_0 $$ directions along the head‐foot (HF) axis, corresponding to head‐first and feet‐first ...

Regional analysis of spatiotemporal trends in Colorado potato beetle abundance

open access: yesPest Management Science, EarlyView.
Leveraging a large data set on Colorado potato beetles in Wisconsin, we examine spatial and temporal abundance trends. Spatiotemporal statistical models substantially improve fit and show that climate and management factors are positively associated with abundance levels.

Extension of Oppenheim's Problem to Bessel Functions

open access: yesJournal of Inequalities and Applications, 2007
Our aim is to extend some trigonometric inequalities to Bessel functions. Moreover, we deduce the hyperbolic analogue of these trigonometric inequalities, and we extend these inequalities to modified Bessel functions.

Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...

Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

3D Nanoprinted Structures Promote Robust Integration of Brain Organoids into Topography‐Guided Neuronal Networks

open access: yesSmall, EarlyView.
Dedicated cultivation platforms facilitate the implementation of brain organoids in guided neuronal networks. Fabrication is enabled by two‐photon polymerization‐based 3D nanoprinting (3DN) and allows for cultivation in standard 12‐well plates. Fine features, namely slopes, funnels, rods, steps, and walls, facilitate and promote organoid positioning ...

Some integral properties in the theory of generalized $k-$Bessel matrix functions

open access: yesJournal of Innovative Applied Mathematics and Computational Sciences
The main purpose of this article is to define some original properties in the theory of the generalized modified $k-$Bessel matrix functions. These special functions, defined in terms of Wright matrix functions, are generalized and their properties ...

Label‐Free YaxAB Nanopore Fingerprinting of Cancer‐Associated Single‐Residue Bcl‐xL Variants

open access: yesSmall Methods, EarlyView.
A YaxAB nanopore workflow enables label‐free single‐molecule fingerprinting of Bcl‐xL variants. Combined normalized current blockade and noise features generated reproducible current fingerprints for wild‐type Bcl‐xL and the cancer‐associated N136K and R165W variants across independent pores, with WT and N136K remaining distinct despite a mass ...
