Regional analysis of spatiotemporal trends in Colorado potato beetle abundance
Pest 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.

International 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
International 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 ...

On approximating the modified Bessel function of the first kind and Toader-Qi mean
Journal of Inequalities and Applications, 2016 In the article, we present several sharp bounds for the modified Bessel function of the first kind I 0 ( t ) = ∑ n = 0 ∞ t 2 n 2 2 n ( n ! ) 2 $I_{0}(t)=\sum_{n=0}^{\infty}\frac{t^{2n}}{2^{2n}(n!)^{2}}$ and the Toader-Qi mean T Q ( a , b ) = 2 π ∫ 0 π ...

Small, 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 ...

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

Bessel-Bessel laser bullets doing the twist
, 2018 Bessel beams carry orbital angular momentum (OAM). Opening up of the Hilbert space of OAM for information coding makes Bessel beams potential candidates for utility in data transfer and optical communication. A laser bullet is the ultra-short and tightly-
