Drivers of 2024 Record Low Sea Ice in Eastern Hudson Bay: A Satellite Era Perspective

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract By late May 2024, Hudson Bay (HB) reached record‐low sea ice extent (SIE) and sea ice concentration (SIC), which has been attributed to the persistent easterly winds in May 2024. This study further investigates the role of easterly winds as well as broader contributing factors.

Constructing Reciprocal Channel Coefficients for Secret Key Generation in FDD Systems [PDF]

, 2018
Physical layer-based key generation encounters the reciprocity bottleneck when applied in frequency-division duplexing (FDD) systems. This letter constructs the reciprocal channel characteristics of the uplink and downlink transmissions for key ...

Drivers of the Functional and Taxonomic Dark Diversity of Regional Flea Assemblages in Four Biogeographic Realms

Ecological Research, Volume 41, Issue 6, November 2026.
The functional and the traditional (= taxonomic) approaches to dark diversity measurement were applied to investigate environmental and host‐associated factors affecting regional dark diversity size and community completeness in four biogeographic realms.

A Thr⁶⁶⁸Ala mutation on APP prevents the short-term memory deficit of FDD_KI mice.

, 2013
(a and b) In RAWM testing, FDDKI/APPTA/TA, FDDKI/APPTA/WT, APPTA/TA, APPTA/WT mice made the same number of errors as WT mice at both 5.5 months and 9 months of age. At 5.5 months of age, FDDKI mice made significantly more errors at A4 (versus FDDKI/APPTA/

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, Volume 309, Issue 10, Page 2897-2912, October 2026.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

FDD Massive MIMO - Antenna Duplex Pattern an-Reciprocity:A Missing Brick

, 2020
Obtaining down link (DL) channel state information (CSI) at the base station (BS) is challenging for frequencydivision-duplex (FDD) massive MIMO (MM) systems. Considerable overhead is required for DL training and feedback.

Estimating Environmental RF‐EMF Exposure From Mobile Networks Using Signal Indicators Collected With the ETAIN 5G Scientist App

Bioelectromagnetics, Volume 47, Issue 7, October 2026.
ABSTRACT Smartphones track indicators of a reference signal to maintain network connectivity. These can serve as proxies for a subset of environmental radiofrequency electromagnetic field (RF‐EMF) exposure from mobile networks. In this multi‐country study, we developed conversion functions linking signal indicators collected with the ETAIN 5G‐Scientist
