3D‐Printable, Honeycomb‐Inspired Tissue‐Like Bioelectrodes for Patient‐Specific Neural Interface

Advanced Materials, EarlyView.
3D printed MRI‐compatible tissue‐like neural electrodes tailored to individual gyral patterns. This honeycomb‐inspired printable gel electrode (HiPGE) employs a bioinspired architecture with soft hydrogels, engineered to match the softness of brain tissue.

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms

Advanced Robotics Research, EarlyView.
A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Tributary Glacier Surges: An Exceptional Concentration at Panmah Glacier, Karakoram Himalaya [PDF]

, 2007
Four tributaries of Panmah Glacier have surged in less than a decade, three in quick succession between 2001 and 2005. Since 1985, 13 surges have been recorded in the Karakoram Himalaya, more than in any comparable period since the 1850s.

A macroscopic approach to glacier dynamics [PDF]

Journal of Glaciology, 2003
AbstractA simple approach to glacier dynamics is explored in which there is postulated to be a relationship between area and volume with three parameters: the time for area to respond to changes in volume, a thickness scale, and an area characterizing the condition of the initial state.This approach gives a good fit to the measurements of cumulative ...

Quantification of seasonal and diurnal dynamics of subglacial channels using seismic observations on an Alpine glacier

The Cryosphere, 2020
. Water flowing below glaciers exerts a major control on glacier basal sliding. However, our knowledge of the physics of subglacial hydrology and its link with sliding is limited because of lacking observations.

Testicular mRNA‐LNP Delivery: A Novel Therapy for Genetic Spermatogenic Disorders

Advanced Science, EarlyView.
In the current study, we developed a novel therapy for genetic spermatogenic disorders. It was revealed that in vivo delivery of mRNA LNP3 could restore spermatogenesis in Msh5D486Y/D486Y and Maps KO mouse models with meiotic arrest. Notably, the offspring without genomic integration was born using ICSI derived from the rescue of Msh5D486Y/D486Y mouse ...

Natural Negative Feedback Loops Confer Indica‐Japonica Differentiation for Grain Size Homeostasis in Rice

Advanced Science, EarlyView.
This study reveals the genetic and molecular mechanisms controlling grain size homeostasis through fine‐tuning OsGRX8 self‐expression by two natural negative feedback loops functioning in redox‐dependent or ‐independent manners and identifies two self‐regulatory haplotypes (SRHs) for the subspecies differentiation in rice.

A Hierarchical Spatio-Temporal Statistical Model Motivated by Glaciology [PDF]

, 2019
In this paper, we extend and analyze a Bayesian hierarchical spatio-temporal model for physical systems. A novelty is to model the discrepancy between the output of a computer simulator for a physical process and the actual process values with a ...

Modelling Dynamics of Valley Glaciers

, 2012
Ever since the Paleoproterozoic snowball Earth era, ca. 2.4 billion years ago (e.g. Hoffman & Schrag, 2000; Kirschvink, 1992), and beyond, the landscape of the planet Earth has been shaped up by the tremendous amount of scouring due to the repeated waxing and waning of ice masses.
