The multi-wavelength phase curves of small bodies: Phase coloring [PDF]
A&A 685, A29 (2024)Context. Small bodies change their brightness due to different motives: Rotation along their axis or axes, combined with irregular shapes and/or changing surface properties, or changes in the geometry of observations. In this work, we tackle the problem of Phase curves, which show the change in brightness due to changes in the fraction of illuminated ...

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Two-Phase Object-Based Deep Learning for Multi-temporal SAR Image Change Detection [PDF]
arXiv, 2020 Change detection is one of the fundamental applications of synthetic aperture radar (SAR) images. However, speckle noise presented in SAR images has a much negative effect on change detection. In this research, a novel two-phase object-based deep learning approach is proposed for multi-temporal SAR image change detection.

Application of Uniform Matrix Product State to Quantum Phase Transition with a Periodicity Change [PDF]
, 2011 As a method beyond the mean-field analysis, a matrix product state (MPS) with incommensurate periodicity is applied to detect phase transitions accompanied with periodicity change, where the incommensurate MPS is generated by acting local-spin-rotation operators with the incommensurate periodicity on a uniform MPS. As a commensurate/commensurate change,

Acta Societatis Botanicorum Poloniae, 2014 It is argued that the phasic alternation of sporophyte and gametophyte in ferns involves changing gene activation during oogenesis and sporogenesis respectively. The reasons for the change in activation are to be sought in the nutritional states of the cells in which the transition takes place. The readiness with Which apospory can the induced in ferns

Energy Saving Techniques for Phase Change Memory (PCM) [PDF]
, 2013 In recent years, the energy consumption of computing systems has increased and a large fraction of this energy is consumed in main memory. Towards this, researchers have proposed use of non-volatile memory, such as phase change memory (PCM), which has ...

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair
FEBS Letters, EarlyView.miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.
