Impact of ENSO on Nitrous Oxide Emissions in the Eastern Tropical Pacific

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Nitrous oxide (N2O ${\mathrm{N}}_{2}\mathrm{O}$) is a powerful greenhouse gas, with the ocean contributing ∼4.2 Tg N y−1 to global N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions. The Eastern Tropical Pacific (ETP) is a hotspot of N2O ${\mathrm{N}}_{2}\mathrm{O}$ emissions due to high N2O ${\mathrm{N}}_{2}\mathrm{O}$ production under low‐oxygen ...

Two-Dimensional AOA Estimation Based on a Constant Modulus Algorithm

International Journal of Antennas and Propagation, 2017
We propose a two-dimensional (2D) angle of arrival (AOA) estimator using the algebraic constant modulus algorithm (ACMA). This algorithm was originally introduced to estimate the one-dimensional (1D) AOA.

A Simple Cross Correlation Switched Beam System (XSBS) for Angle of Arrival Estimation

IEEE Access, 2017
We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with a single radio frequency ...

Inferring Helmet Compliance on E-Scooters Using Bluetooth and Angle-of-Arrival (AoA) Technology

IEEE Transactions on Instrumentation and Measurement
The use of e-scooters and the associated head injuries have increased significantly in recent years. To protect the head and face of the riders, helmets are essential equipment, sometimes mandatory according to the regulations, which makes them an important research target. In this article, we propose a practical helmet monitoring system for e-scooters

Conjoined Parasitic Twins (Cephalo‐Thoracopagus Parasiticus) in a Free Ranging Northern Bat (Eptesicus nilssonii): A Micro‐CT Anatomic and Genetic Survey

Anatomia, Histologia, Embryologia, Volume 55, Issue 2, March 2026.
ABSTRACT The detailed anatomical situation of male stillborn cephalo‐thoracopagus twins in a wild ranging northern bat (Eptesicus nilssonii) is described by means of full body micro‐CT scans in high resolution with three‐dimensional computational reconstruction.

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

An indoor variance-based localization technique utilizing the UWB estimation of geometrical propagation parameters [PDF]

, 2018
A novel localization framework is presented based on ultra-wideband (UWB) channel sounding, employing a triangulation method using the geometrical properties of propagation paths, such as time delay of arrival, angle of departure, angle of arrival, and ...

A Comparative Analysis of Intratesticular Versus Intra‐Epididymal Injections of Clove Essential Oil on Male Dog Sterilization

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This study evaluated clove essential oil as a non‐surgical sterilant in male dogs. Both intratesticular and intra‐epididymal injections significantly reduced sperm concentration, motility and viability, with histological and sonographic evidence of reproductive tissue damage.
