Search for microscopic black holes in a like-sign dimuon final state using large track multiplicity with the ATLAS detector

2013

A search is presented for microscopic black holes in a like-sign dimuon final state in proton-proton collisions at √s= 8 TeV. The data were collected with the ATLAS detector at the Large Hadron Collider in 2012 and correspond to an integrated luminosity of 20.3 fb-1. Using a high track multiplicity requirement, 0.6±0.2 background events from Standard Model processes are predicted and none observed. This result is interpreted in the context of low-scale gravity models and 95% CL lower limits on microscopic black hole masses are set for different model assumptions.

Search for strong gravity signatures in same-sign dimuon final states using the ATLAS detector at the LHC

2012

A search for microscopic black holes has been performed in a same-sign dimuon final state using 1.3 fb[superscript −1] of proton–proton collision data collected with the ATLAS detector at a centre of mass energy of 7 TeV at the CERN Large Hadron Collider. The data are found to be consistent with the expectation from the Standard Model and the results are used to derive exclusion contours in the context of a low scale gravity model.

Memristors in Nonlinear Network : Application to Information (Signal and Image) Processing

2021

Memristor is a two-terminal nonlinear dynamic electronic device. Typically, it is a passive nano-device whose conductivity is controlled by the flux, time-integral of the voltage across its terminals, or by the charge, time-integral of the current flowing through it, and it presents interesting features for versatile applications. This thesis considers memristor use as a neighborhood connection for 2D cellular nonlinear or neural network (CNN), essentially for information (image and signal) processing and electronic prosthesis. We develop a model of the memristor based 2D cellular nonlinear networks CNNs compatible to image applications by incorporating memristor in the adjacent neighborhoo…

Investigación inter e intra-variable del valor percibido: un modelo causal de segundo orden y satisfacción cognitiva y afectiva

2017

El valor percibido es axiomática y epistemológicamente clave para el Marketing. Su investigación es rica y profunda respecto a su dimensionalidad (análisis intra-variable) y a su relación con satisfacción y lealtad (inter-variable). Como contribución a la abundante literatura sobre medición del valor percibido en servicios turísticos, este trabajo propone un modelo causal que abarca las perspectivas inter e intra-variable, y propone el valor percibido como segundo orden y la cadena valor-satisfacción-lealtad, con una bifurcación de la satisfacción en afectiva y cognitiva. El modelo es testado con PLS sobre una muestra de 340 huéspedes de hotel en la Comunidad Valenciana, hallando contribuci…

Calculations of Starting Currents and Frequencies in Frequency-Tunable Gyrotrons

2012

Cold cavity and self-consistent formalisms for starting current and frequency calculations in frequency-tunable gyrotrons are summarized. Numerical solution schemes of the corresponding equations are discussed. A specific case is analyzed in detail.

A simple proof of the polylog counting ability of first-order logic

2007

The counting ability of weak formalisms (e.g., determining the number of 1's in a string of length N ) is of interest as a measure of their expressive power, and also resorts to complexity-theoretic motivations: the more we can count the closer we get to real computing power. The question was investigated in several papers in complexity theory and in weak arithmetic around 1985. In each case, the considered formalism (AC 0 -circuits, first-order logic, Δ 0 ) was shown to be able to count up to a polylogarithmic number. An essential part of the proofs is the construction of a 1-1 mapping from a small subset of {0, ..., N - 1} into a small initial segment. In each case the expressibility of …

A Test of the Relationship Between Argumentativeness and Individualism/Collectivism in the United States and Finland

2016

This study explored relationships between argumentativeness and collectivism/individualism in Finland and the United States. Data were gathered in the United States (n = 412) and Finland (n = 261). The analysis suggested: (a) collectivism was negatively correlated with argumentativeness, (b) individualism was positively correlated with argumentativeness, and (c) Finnish participants reported lower levels of argumentativeness than Americans. Cultural differences between the United States and Finland are discussed as reasons for the differences between the nations on argumentativeness.

Smart city. Four approaches to the concept of understanding

2020

The paper analyzes the rhetoric of the smart city (SC) concept in order to recognize, categorize, and describe different perspectives of understanding the notion. Four approaches to the SC concept were isolated: three affirmative, and one rejecting. The approaches present a different understanding of the SC and indicate different elements creating urban ‘smartness.’ Despite differences, there is one common goal in every affirmative approach: to improve the quality of urban life. It is achieved through activities covering five dimensions distinguished within affirmative approaches. Together they can serve, i.e.,as a framework for SC case study analyses.
