$${\text{Co}}_{x}{\text{Zn}}_{1-x}{\text{O}}$$ (x = 0.00, 0.04, 0.08, and 0.10) thin films were sprayed pyrolysis onto ordinary glass substrates. The micro-Raman spectroscopy revealed the presence of wurtzite structure in all films. UV–Vis investigation showed good optical transmittance visible region with increase absorption bands related to internal $${\text{Co}}^{+2}$$ d–d transitions over C...

In this work, we report the development and performance of single-gap timing RPCs equipped with a 3mm FWHM resolution bidimensional position-sensitive readout and reaching a timing resolution of 55 ps s at an efficiency of 75% for MIPs. These chambers are aimed to be applied in a multilayer geometry, forming small and very accurate TOF systems. The avalanche localization capability would provid...

Fourteen different morphological traits in 169 and 131 cattle of Oulmes-Zaer and Tidili, respectively were recorded and analyzed using a multivariate approach. The characters measured included heart girth, wither height, rump height, rump length, rump width, chest depth, body length, neck length, cannon circumference, ear length, ear width, head length, horn length and tail length. Breed signif...

It is shown that a local bend of a nanowire is a source of pinning potential for a transversal head-to-head (tail-to-tail) domain wall. Eigenfrequency of the domain wall free oscillations at the pinning potential and the effective friction are determined as functions of the curvature and domain wall width. The pinning potential originates from the effective curvature-induced Dzyaloshinsky-like ...

Amorphous semiconductors are materials with a brilliant prospect for a wide range of optical applications like solar cells, optical sensors, optical devices, and memories. The purpose of the present research was to study the semiconducting optical properties of SiO2-Al2O3-CaF2 and SiO2-Al2O3-BaF2 oxyfluoride...

The membrane and actin cortex of a motile cell can autonomously differentiate into two states, one typical of the front, the other of the tail. On the substrate-attached surface of Dictyostelium discoideum cells, dynamic patterns of front-like and tail-like states are generated that are well suited to monitor transitions between these states. To image large-scale pattern dynamics independently ...

Measuring the finite width and unitarity corrections to the φω mixing amplitude. Abstract It is shown that the phase of φω interference in the reaction e + e − → π + π − π 0 at energies close to the φ(1020) peak can be calculated in a way that is practically independent of the model of φω mixing. The magnitude of the presently measured interference phase, still of poor accuracy, is in agreement...

Experimental tests have been carried out for characterizing the performance of a new single-photon avalanche diode. The detector is specifically designed for picosecond timecorrelated single photon counting, aiming to obtain a time response free from the tail effects and/or secondary bumps observed in all other available single-photon detectors. The experimental results confirm that an unpreced...
