SELECTIVE SURFACES FOR NATURAL COOLING DEVICES

Le Journal de Physique Colloques, 1981
Extra-atmospheric space is practically a pure sink of radiation, and can be used as a nonconventional energy source. Surfaces with an emissivity matched with the atmospheric (8 ÷ 13) µm transparency window interact with cold space when exposed to clear sky at night, and undergo a sizeable cooling effect.

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Road Surface Classification Using a Deep Ensemble Network with Sensor Feature Selection

Sensors, 2018
Deep learning is a fast-growing field of research, in particular, for autonomous application. In this study, a deep learning network based on various sensor data is proposed for identifying the roads where the vehicle is driving.

Minimum Surface Bhattacharyya feature selection [PDF]

2009 First Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing, 2009
This paper introduces a novel feature selection method called Minimum Surface Bhattacharyya (MSB). The method is applicable for multiple class problems utilizing supervised training. The minimum surface method selects features by means of inter-class separability.

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

FEBS 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.

Angle-selective surface based on aperture-coupled frequency-selective surface

Physica Scripta
Abstract In this work, we propose a dual-polarized angle-selective surface (DASS) based on a compact double-layer aperture-coupled frequency-selective surface. The electromagnetic coupling between the compact aperture layers is leveraged to modify the equivalent permittivity and permeability along the normal direction, resulting in ...

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Visual Inspection of Machined Metallic High-Precision Surfaces

EURASIP Journal on Advances in Signal Processing, 2002
This paper presents a surface inspection prototype of an automatic system for precision ground metallic surfaces, in this case bearing rolls. The surface reflectance properties are modeled and verified with optical experiments.

Quasiattractors in coupled maps and coupled dielectric cavities

, 2012
We study the origin of attracting phenomena in the ray dynamics of coupled optical microcavities. To this end we investigate a combined map that is composed of standard and linear map, and a selection rule that defines when which map has to be used.
