Fermion pair production in e+e- collisions at 189-209 GeV and constraints on physics beyond the Standard Model

2006

Cross sections, angular distributions and forward-backward asymmetries are presented, of two-fermion events produced in e+e- collisions at centre-of-mass energies from 189 to 209 GeV at LEP, measured with the ALEPH detector. Results for e+e-, mu+mu-, tau+tau-, qq, bb and cc production are in agreement with the Standard Model predictions. Constraints are set on scenarios of new physics such as four-fermion contact interactions, leptoquarks, Z' bosons, TeV-scale quantum gravity and R-parity violating squarks and sneutrinos.

Mobile phone use and exposures in children.

2005

The main difference concerning the use of mobile phones (MPs) between today's children and adults is the longer lifetime exposure of children when they grow older, due to starting to use MPs at an early age. Additionally, recent trends lead to a higher frequency of use among children, including higher popularity of MPs and features specifically designed to attract children. The prevalence of MP users is already very high and reaches >90% among adolescents in some countries. In a German study, 6% of 9-10 years old children used a MP for making calls daily; 35% owned their own MP. For children, MPs are dominant sources of radio wave exposures and relevant sources of extremely low frequency ma…

Reference-Plane Invariant Method for Measuring Electromagnetic Parameters of Materials

2010

This paper presents a simple and effective wideband method for the determination of material properties, such as the complex index of refraction and the complex permittivity and permeability. The method is explicit (non-iterative) and reference-plane invariant: it uses a certain combination of scattering parameters in conjunction with group-velocity data. This technique can be used to characterize both dielectric and magnetic materials. The proposed method is verified experimentally within a frequency range between 2 to 18 GHz on polytetrafluoroethylene and polyvinylchloride samples. A comprehensive error and stability analysis reveals that, similar to other methods based on transmission/re…

An Emphatic Humanoid Robot with Emotional Latent Semantic Behavior

2008

In this paper we propose an Entertainment Humanoid Robot model based on Latent Semantic Analysis, that tries to exhibit an emotional behavior in the interaction with human. Latent Semantic Analysis (LSA), based on vector space allows the coding of the words semantics by specific statistical computations applied to a large corpus of text. We illustrate how the creation and the use of this emotional conceptual space can provide a framework upon which to build “Latent Semantic Behavior” because it simulates the emotionalassociative capabilities of human beings. This approach integrates traditional knowledge representation with intuitive capabilities provided by geometric and sub-symbolic infor…

Background Digital gaming is one of the most popular forms of entertainment in the world. While prior literature concluded that digital games can enable changes in players’ behaviors, there is limited knowledge about different types of behavior changes and the game features driving them. Understanding behavior changes and the game features behind them is important because digital games can motivate players to change their behavior for the better (or worse). Objective This study investigates the types of behavior changes and their underlying game features within the context of the popular pervasive game Pokémon GO. Methods We collected data from 262 respondents with a critical incident tech…

Approach of the State Pharmacopeia of Ukraine to analytical procedures validation on the example of chloride ions assay in peritoneal dialysis soluti…

2019

The objective of this study was to develop and validate an alternative analytical procedure for the total chloride assay in solutions for peritoneal dialysis (PD). The proposed analytical procedure was validated according to the requirements of the International Conference on Harmonization (ICH) Guideline: Topic ICH Q2(R1) and the approach of the State Pharmacopeia of Ukraine (SPU). The analytical procedure was specific. The li-nearity of the procedure was evaluated in the concentration range of 76 to 114 mmol/L of chloride ions (80-120% of the stated content (95 mmol/L)) with the regression equation y = 1.0029 ∑ X -0.2269 and a correlation coefficient of 0.9989. The y-intercept of the regr…

Who sent the e-mail?

2003

In mid October 2001, a number of lecturers at the University of Valencia received insulting, threatening and anonymous electronic mails. An investigation about this fact is only permitted under very restricted conditions, stipulated by the Spanish law of the Secrecy of Communications. Only one judicial authority is able to lift these restrictions and authorize information to be checked in order to obtain enough evidence to unveil who was responsible for the messages. The authors propose in this paper a study for quantifying the weight of certain evidence with a view to show to the judge that the relevance of the said weight would justify such a measure.

A study of the material in the ATLAS inner detector using secondary hadronic interactions

2011

The ATLAS inner detector is used to reconstruct secondary vertices due to hadronic interactions of primary collision products, so probing the location and amount of material in the inner region of ATLAS. Data collected in 7 TeV pp collisions at the LHC, with a minimum bias trigger, are used for comparisons with simulated events. The reconstructed secondary vertices have spatial resolutions ranging from ~ 200μm to 1 mm. The overall material description in the simulation is validated to within an experimental uncertainty of about 7%. This will lead to a better understanding of the reconstruction of various objects such as tracks, leptons, jets, and missing transverse momentum.
