Deriving iceberg ablation rates using an on-iceberg autonomous phase-sensitive radar (ApRES)

Annals of Glaciology
The increase in iceberg discharge into the polar oceans highlights the importance of understanding how quickly icebergs are deteriorating and where the resulting freshwater injection is occurring.

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators

Advanced Engineering Materials, EarlyView.
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips

Advanced Functional Materials, EarlyView.
This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...

Development of a semi-persistent floating terminus at San Quintín Glacier (Northern Patagonia Icefield), the last piedmont glacier in the Andes

Annals of Glaciology
The piedmont lobe of San Quintín Glacier, the largest outlet of the Northern Patagonia Icefield, has recently entered a phase of rapid frontal retreat. We present results from a helicopter-borne ground-penetrating radar (GPR) survey conducted in May 2019

Comparing numerical ice-sheet model output with radio-echo sounding measurements in the Weddell Sea sector of West Antarctica

Annals of Glaciology, 2020
Numerical ice-sheet models are commonly matched to surface ice velocities from InSAR measurements by modifying basal drag, allowing the flow and form of the ice sheet to be simulated. Geophysical measurements of the bed are rarely used to examine if this

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

ImpDAR: an open-source impulse radar processor

Annals of Glaciology, 2020
Despite widespread use of radio-echo sounding (RES) in glaciology and broad distribution of processed radar products, the glaciological community has no standard software for processing impulse RES data.

Radio echo-sounding of the Antarctic ice sheet.

Journal of the Japanese Society of Snow and Ice, 1989
氷床流動の観測に基づいて, 南極氷床の変動 (例えば, 氷床域の拡大, 縮小) を明らかにすることを目的として, 東南極の東経35度から東経45度に至るみずほ高原地域において, 過去20年にわたって観測が続けられてきた.その結果, 白瀬氷河流域では.年間約70cmもの氷厚の減少が観測された.この氷厚減少から, 白瀬氷河流域の氷床が不安定状態にあることが示唆され, 原因として, 氷床底面での“底面すぺり”が指摘された。そこで, 氷床底面の物理的状態を調べるために電波氷厚計を用いての電波探査が氷床上の流動測定・雪氷観測ルートに沿って, 1982年以降実施された.これまでの電波観測では, 送信時刻と基盤からの反射時刻の時間間隔から氷厚のみを求めていたが, この研究では, 氷床氷の厚さを測定するだけでなく,

Multimodal Optoelectronic Synapses for Neuromorphic Intelligence: Coupling Light, Electrical, Thermal, and Beyond

Advanced Functional Materials, EarlyView.
This review revisits optoelectronic neuromorphic devices that extend from unimodal sensing toward multimodal perception. Five types of stimuli‐to‐output information flow that are classified based on the device roles within the system and applications are summarized and discussed.
