Ice stream or not? Radio-echo sounding of Carlson Inlet, West Antarctica [PDF]
The Cryosphere, 2011 The Antarctic Ice Sheet loses mass to the surrounding ocean mainly by drainage through a network of ice streams: fast-flowing glaciers bounded on either side by ice flowing one or two orders of magnitude more slowly.

Airborne radio echo sounding on the Shirase Glacier and its drainage basin, East Antarctica
Antarctic Record, 1981 Airborne radio echo sounding carried out on the Shirase Glacier and its drainage basin in January 1980 is described. The new sounder (NIPR-A) was operated at 179 MHz on board a Pilatus Porter PC-6.

Layer optimized SAR processing and slope estimation in radar sounder data
Journal of Glaciology, 2019 Englacial layers in Antarctica and Greenland are indicators of the dynamic, rheological and subglacial configuration of the ice sheets. Airborne radar sounder data is the primary remote sensing solution for directly observing englacial layers and ...

Annals of Glaciology, 2020 Radar surveys across ice sheets typically measure numerous englacial layers that can often be regarded as isochrones. Such layers are valuable for extrapolating age–depth relationships away from ice-core locations, reconstructing palaeoaccumulation ...

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Results from the Radio Echo-Sounding on Parts of the Jostedalsbreen Ice Cap, Norway
, 1986 The paper describes instrumentation, navigation methods, and interpretation problems from radio echo-sounding on parts of Jostedalsbreen. A map of the subglacial topography is presented.

Radio-echo Sounding at the Mittivakkat Gletscher, Southeast Greenland [PDF]
Arctic, Antarctic, and Alpine Research, 1999 Profiles along sounding lines and maps are presented of the glacier surface, bottom topography, and ice thickness of Mittivakkat Gletscher. The maps are the result of the use of monopulse radio-echo sounding of ice thickness in about 450 points along profiles across the glacier.

The ubiquitin system in normal and infected germinal center B cells
FEBS Letters, EarlyView.The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
