Anisotropic flow of identified hadrons in Xe-Xe collisions at √sNN = 5.44 TeV

Measurements of elliptic (v2) and triangular (v3) flow coefficients of π±, K±, p+p ¯ , KS0, and Λ+Λ ¯ obtained with the scalar product method in Xe-Xe collisions at sNN = 5.44 TeV are presented. The results are obtained in the rapidity range |y| < 0.5 and reported as a function of transverse momentum, pT, for several collision centrality classes. The flow coefficients exhibit a particle mass depen

Analysis of mammograms using artificial intelligence to predict response to neoadjuvant chemotherapy in breast cancer patients : proof of concept

Objectives: In this proof of concept study, a deep learning–based method for automatic analysis of digital mammograms (DM) as a tool to aid in assessment of neoadjuvant chemotherapy (NACT) treatment response in breast cancer (BC) was examined. Methods: Baseline DM from 453 patients receiving NACT between 2005 and 2019 were included in the study cohort. A deep learning system, using the aforementio

Outcome and predictors in simple decompression of ulnar nerve entrapment at the elbow

Objectives: Simple decompression is an accepted surgical treatment of ulnar nerve entrapment at the elbow (UNE). Our purpose was to evaluate the outcome and potential predictors for the outcome after simple decompression in UNE.Methods: All surgically treated UNE cases (from 2004-2008) at our department were studied retrospectively. Out of 285 primary surgeries, 242 primary simple ulnar nerve deco

Virtual Clinical Trials in Medical Imaging System Evaluation and Optimisation

Virtual clinical trials (VCTs) can be used to evaluate and optimise medical imaging systems. VCTs are based on computer simulations of human anatomy, imaging modalities and image interpretation. OpenVCT is an open-source framework for conducting VCTs of medical imaging, with a particular focus on breast imaging. The aim of this paper was to evaluate the OpenVCT framework in two tasks involving dig

Luminescence chronology of a Mass Grave of Giant Gopher Tortoises (Gopherus hexagonatus)

A rare fossiliferous site in Willacy County, Texas, contains a mass concentration of fossil Giant Gopher Tortoises (Gopherus hexagonatus). The site southeast of Raymondville was exposed in the late 1980s during archaeological surveys for drainage canal improvements. Numerous large adults with complete shells were recovered along with partial limb, cranial, and vertebral elements. Especially remark

Maternal separation leads to regional hippocampal microglial activation and alters the behavior in the adolescence in a sex-specific manner

Early life adversities during childhood (such as maltreatment, abuse, neglect, or parental deprivation) may increase the vulnerability to cognitive disturbances and emotional disorders in both, adolescence and adulthood. Maternal separation (MS) is a widely used model to study stress-related changes in brain and behavior in rodents. In this study, we investigated the effect of MS (postnatal day 2–

The effect of electroconvulsive therapy on neuroinflammation, behavior and amyloid plaques in the 5xFAD mouse model of Alzheimer's disease

Microglial cells are affected in Alzheimer's disease (AD) and interact with amyloid-beta (Aβ) plaques. Apart from memory loss, depression is common in patients with AD. Electroconvulsive therapy (ECT) is an anti-depressive treatment that may stimulate microglia, induce neuroinflammation and alter the levels of soluble Aβ, but the effects of ECT on microglia and Aβ aggregation in AD are not known.

A multiphonic harmonic on vibraphone (pedagogy - video)

This video presents what seems to be an unreported multiphonic harmonic on the vibraphone. For the vibraphone, a common technique in contemporary literature features the isolation and production of a single harmonic (h04) in the lower octave. However, through experiments by Olaf Tzschoppe (DE) and Michael Edgerton (SE) on the vibraphone, an unreported multiphonic was found on the lowest thirteen b

Multiharmonic Correlations of Different Flow Amplitudes in Pb-Pb Collisions at sNN =2.76 TeV

The event-by-event correlations between three flow amplitudes are measured for the first time in Pb-Pb collisions, using higher-order symmetric cumulants. We find that different three-harmonic correlations develop during the collective evolution of the medium when compared to correlations that exist in the initial state. These new results cannot be interpreted in terms of previous lower-order flow

On the relationships among wheel-rail surface topography, interface noise and tribological transitions

Noise from the wheel-rail interface is a troublesome side effect when railway vehicles negotiate rail curves. In this laboratory study, two pin-on-disc tribometers were used to simulate the pure sliding process in the wheel-rail contact. The purpose was to investigate the relationships between surface topographies, tribological aspects and the emitted noise. Five different surface topographies man

Challenges and solutions for antennas in Vehicle-to-Everything services

Autonomous vehicle is being developed for widespread deployment. Its reliability and safety are critically dependent on advanced wireless technologies, e.g., vehicle-to-everything (V2X) communication. The frontend of a V2X system needs an antenna module that enables the vehicle to reliably connect to all other networks. Designing V2X antenna is challenging due to the complex in-vehicle environment

Social-Ecological System Transformation and Learning: the case of Santa Rosa de Lima’s dairy system, Brazil

Conventional pastureland management has brought Southern Brazilian dairy farms to a financial and environmental crisis. In this context, the management-intensive grazing system (MIG) emerges as a viable alternative to conventional pastureland management. This study aims to analyze the Social-Ecological System (SES) transformation process of the dairy system in Santa Rosa de Lima, Southern Brazil,
