Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

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.

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.

Comparison and verification of enthalpy schemes for polythermal glaciers and ice sheets with a one-dimensional model [PDF]

open access: yes, 2015
The enthalpy method for the thermodynamics of polythermal glaciers and ice sheets is tested and verified by a one-dimensional problem (parallel-sided slab).

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Method for fabricating solar cells having integrated collector grids [PDF]

open access: yes, 1979
A heterojunction or Schottky barrier photovoltaic device comprising a conductive base metal layer compatible with and coating predominately the exposed surface of the p-type substrate of the device such that a back surface field region is formed at the ...

Thinning CsPb2Br5 Perovskite Down to Monolayers: Cs-dependent Stability [PDF]

open access: yes, 2017
Using first-principles density functional theory calculations, we systematically investigate the structural, electronic and vibrational properties of bulk and potential single-layer structures of perovskite-like CsPb2Br5 crystal.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

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,
