Dissociable laminar profiles of concurrent bottom-up and top-down modulation in the human visual cortex

open access: yeseLife, 2019
Recent developments in human neuroimaging make it possible to non-invasively measure neural activity from different cortical layers. This can potentially reveal not only which brain areas are engaged by a task, but also how.

Double-layer structure in the boundary layer over the Baltic Sea

open access: yes, 2005
Double-layered structures found over the Baltic Sea are investigated using radiosoundings and lidar measurements. Situations with double-layer structures are also simulated with the regional model REMO in a realistic manner.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Quantitative study on the water vapor transport characteristics of an extreme precipitation event in North China

open access: yesAtmospheric Science Letters
North China experienced an extreme precipitation event from July 29 to August 1, 2023 (i.e., the “23.7” event) causing severe floods, significant infrastructure damage and multiple fatalities.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Feeding Condition and Strain Difference Influence Sleeping Behavior in Newborn Chicks

open access: yesThe Journal of Poultry Science, 2003
To clarify sleeping behavior of neonatal chicks, two experiments were conducted. In Experiment 1, the contribution of feeding on sleeping behavior was investigated over a 24 h period. Newly hatched layer-type chicks were kept under continuous lighting,

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Layered predicates

open access: yesDAIMI Report Series, 1992
We review the concept of logical relations and how they interact with structural induction, furthermore we give examples of their use, and of particular interest is the combination with the PER-idea (partial equivalence relations). This is then generalized to Kripke logical relations; the major application is to show that in combination with the PER ...

Enabling Realistic Cross-Layer Analysis based on Satellite Physical Layer Traces [PDF]

open access: yes, 2012
We present a solution to evaluate the performance of transport protocols as a function of link layer reliability schemes (i.e. ARQ, FEC and Hybrid ARQ) applied to satellite physical layer traces.
