Real-time reflectance-difference spectroscopy of GaAs molecular beam epitaxy homoepitaxial growth

open access: yesAPL Materials, 2014
We report on real time-resolved Reflectance-difference (RD) spectroscopy of GaAs(001) grown by molecular beam epitaxy, with a time-resolution of 500 ms per spectrum within the 2.3–4.0 eV photon energy range.

A New Algorithm for Detecting GPN Protein Expression and Overexpression of IDC and ILC Her2+ Subtypes on Polyacrylamide Gels Associated with Breast Cancer

open access: yesAlgorithms
Sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE) is used to identify protein presence, absence, or overexpression and usually, their interpretation is visual.

Frontiers of Bright CEP‐Stable Broadband Infrared Sources

open access: yesLaser &Photonics Reviews, EarlyView.
Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.

With Regard to the Expression Status of Sarcolemmal Aquaporin 4 in Human Muscular Dystrophies

open access: yesNeurology and Clinical Neuroscience, EarlyView.
ABSTRACT Human muscular dystrophies are inherited muscle‐wasting diseases caused by the various kinds of gene mutations. Among them, Duchenne muscular dystrophy (DMD) is a representative type. Before the discovery of the causative dystrophin gene of DMD, the fragile myofiber plasma membrane was thought to be the trigger of myofiber necrosis in DMD ...

Hermite Functions, Lie Groups and Fourier Analysis

open access: yesEntropy, 2018
In this paper, we present recent results in harmonic analysis in the real line R and in the half-line R + , which show a closed relation between Hermite and Laguerre functions, respectively, their symmetry groups and Fourier analysis. This

Proteomic profile of CSF obtained at the time of diagnosis determines amyotrophic lateral sclerosis progression and survival: CXCL7 levels in disease prognosis and survival

open access: yesBrain Pathology, EarlyView.
Untargeted multiomic profiling of cerebrospinal fluid reveals that proteomic, but not lipidomic, signatures robustly distinguish ALS patients from controls and stratify individuals by survival, highlighting marked molecular differences between short survival and long survival disease.
