Muon-electron lepton-flavor-violating transitions : Shell-model calculations of transitions in 27Al

2018

In this paper we present the results of large-scale shell-model calculations of muon-to-electron lepton-flavorviolating transitions for the case of the target nucleus 27Al. We extend the previous shell-model calculations, done in the sd model space, by including also the p orbitals in order to see whether the negative-parity states produce any significant effect in the conversion rate. The analysis of the results shows the dominance of coherent transitions mediated by isovector operators and going by the ground state of the target, with practically null influence of excited positive- or negative-parity states. peerReviewed

Guidelines for biomarker discovery in endometrium: correcting for menstrual cycle bias reveals new genes associated with uterine disorders

2021

Abstract Transcriptomic approaches are increasingly used in reproductive medicine to identify candidate endometrial biomarkers. However, it is known that endometrial progression in the molecular biology of the menstrual cycle is a main factor that could affect the discovery of disorder-related genes. Therefore, the aim of this study was to systematically review current practices for considering the menstrual cycle effect and to demonstrate its bias in the identification of potential biomarkers. From the 35 studies meeting the criteria, 31.43% did not register the menstrual cycle phase. We analysed the menstrual cycle effect in 11 papers (including 12 studies) from Gene Expression Omnibus: t…

Comparative study of molecular processes and factors affecting endometrial function in subfertile patients with uterine disorders

2021

El endometrio humano es un tejido dinámico y complejo que solo es receptivo al embrión durante un corto periodo de tiempo. Por lo tanto, la identificación de trastornos y factores que impidan que el endometrio adquiera un fenotipo receptivo es crucial para poder prevenir fallos de implantación embrionaria y aumentar las tasas de embarazo. Los trastornos uterinos son complejos, multifactoriales y poligénicos y a menudo comprometen la fertilidad femenina, aunque se desconoce con exactitud cómo afectan a la adquisición de la receptividad endometrial. Además, estos trastornos carecen actualmente de un tratamiento efectivo, a menudo presentan comorbilidad entre ellos y su incidencia aumenta con …

Forensic tools for the diagnosis of electrocution death: Case study and literature review

2018

Diagnosis of death by electrocution may be difficult when electric marking is not visible or unclear. Accordingly, the body of a man who appeared to have died from accidental electrocution was carefully forensically analysed. Macroscopic and microscopic analysis of the current mark was carried out using a variable-pressure scanning electron microscope equipped with energy dispersive X-ray microanalyser to highlight skin metallisation, indicating the presence of iron and zinc. The histological findings of electrocution myocardial damage were supported by the results of biochemical analysis which demonstrated the creatine kinase-MB and cardiac troponin I elevation. The effects of electric cu…

Addition of strength training to off-road cyclists training : A pilot study

2016

This study investigated the effects of adding a traditional strength training approach (endurance-strength = ES) during the pre-season versus a non-traditional approach where strength training is further maintained throughout the season (maximal-strength = MS), on aerobic and anaerobic parameters of off-road cyclists. Eleven off-road cyclists were divided into two groups. The ES group (n=6) performed during the first 8 weeks endurance-strength training, while the MS group (n=5) performed maximal-strength training, both together with their usual endurance training. During the following 8 weeks, only MS group maintained 1 session of strength training per week. 1RM, VO2max, Maximal aerobic pow…

The Large Hadron–Electron Collider at the HL-LHC

2021

The Large Hadron-Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). The accelerator and interaction region are designed for concurrent electron-proton and proton-proton operations. This report represents an update to the LHeC's conceptual design report (CDR), published in 2012. It comprises new results on the parton structure of the proton and heavier nuclei, QCD dynamics, and electroweak and top-quark physics. It is shown how the LH…

The Relationship between Employee Environmental Awareness and Current Environmental Management System

2020

Background. Many publications have studied environmental management systems. Once a system is implemented and maintained, it should affect employee environ­mental awareness – the question is to what extent it does so. To date, published studies have defined awareness and highlighted its importance. The author, as a practitioner, was interested in whether the positive opinion about the system expressed in the system documentation (audit reports) was relevant for the development of environmental awareness of managers and employees. Research aims. Therefore, the purpose of this article was to establish the relationship between the state of the environmental management system and the environmen…

First measurement of proton's charge form factor at very low $Q^2$ with initial state radiation

2017

We report on a new experimental method based on initial-state radiation (ISR) in e-p scattering, in which the radiative tail of the elastic e-p peak contains information on the proton charge form factor ($G_E^p$) at extremely small $Q^2$. The ISR technique was validated in a dedicated experiment using the spectrometers of the A1-Collaboration at the Mainz Microtron (MAMI). This provided first measurements of $G_E^p$ for $0.001\leq Q^2\leq 0.004 (GeV/c)^2$.
