Selective writing and read-out of a register of static qubits

2013

We propose a setup comprising an arbitrarily large array of static qubits (SQs), which interact with a flying qubit (FQ). The SQs work as a quantum register, which can be written or read-out by means of the FQ through quantum state transfer (QST). The entire system, including the FQ's motional degrees of freedom, behaves quantum mechanically. We demonstrate a strategy allowing for selective QST between the FQ and a single SQ chosen from the register. This is achieved through a perfect mirror located beyond the SQs and suitable modulation of the inter-SQ distances.

Like Parents, like Teenagers: A Romanian Youth Smoking Overview

2015

AbstractThis paper estimates how family model influences youth's smoking behaviors and describes smoking behavior in Romania nowadays. A questionnaire-based survey was used and data was collected from a national sample (1,364 people: 536 male and 828 female; average age 22,71 years and SD=3,128). The paper analyses only the items relevant for smoking behavior.Using a quasi-experimental design, we found a significant difference determinated by father's model (ρ(1364)= 0,158, p < 0,05), mother's model (ρ(1362)=0,155, p < 0,05), and brothers/sisters’ model (ρ(1362)=0,219, p < 0,05), regarding smoking behavior.Keywords: smoking behaviour, Romanian teenagers, parental model, Health Psychology

Applications of Microlocal Analysis in Inverse Problems

2020

This note reviews certain classical applications of microlocal analysis in inverse problems. The text is based on lecture notes for a postgraduate level minicourse on applications of microlocal analysis in inverse problems, given in Helsinki and Shanghai in June 2019.

Cost that is Directly Incurred as a Result of Operating the Train Service on the 1520 mm Rail with Primarily Freight Transportation

2016

AbstractUnder the Directive 2012/34/EU (21 November 2012) “the charges for … [rail] infrastructure … shall be set at the cost that is directly incurred as a result of operating the train service”. This charging rule is new for Baltic States’ railways, where due to the favorable geographic position a full cost application without detalization was possible. Although, a big number of relevant studies on the issue was made in EU, all of them covered only 1435mm railways with primarily passenger transportation. This study has been made in order to understand the impact of train operating on 1520mm rail infrastructure with primarily freight transportation.A gradual model of infrastructure chargin…

Automated Railway Signs Detection. Preliminary Results

2019

Abstract Nowadays safety in railways is mostly achieved by automated system technologies such as ERTMS/ETCS. Nevertheless, on local railways (suburban and regional lines) several tasks still depend on the choices and actions of a human crew. With the aim to improve safety in such type of railways, this research proposes a system for the automatic detection and recognition of railway signs by means of the digital image processing technique. First field applications, carried out on the Italian railway network, show that the proposed system is very accurate (the percentage of correctly detected railway signs is about 97%), even at high train speeds.

Generalized wave propagation problems and discrete exterior calculus

2018

We introduce a general class of second-order boundary value problems unifying application areas such as acoustics, electromagnetism, elastodynamics, quantum mechanics, and so on, into a single framework. This also enables us to solve wave propagation problems very efficiently with a single software system. The solution method precisely follows the conservation laws in finite-dimensional systems, whereas the constitutive relations are imposed approximately. We employ discrete exterior calculus for the spatial discretization, use natural crystal structures for three-dimensional meshing, and derive a “discrete Hodge” adapted to harmonic wave. The numerical experiments indicate that the cumulat…

Global Estimation of Biophysical Variables from Google Earth Engine Platform

2018

This paper proposes a processing chain for the derivation of global Leaf Area Index (LAI), Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), Fraction Vegetation Cover (FVC), and Canopy water content (CWC) maps from 15-years of MODIS data exploiting the capabilities of the Google Earth Engine (GEE) cloud platform. The retrieval chain is based on a hybrid method inverting the PROSAIL radiative transfer model (RTM) with Random forests (RF) regression. A major feature of this work is the implementation of a retrieval chain exploiting the GEE capabilities using global and climate data records (CDR) of both MODIS surface reflectance and LAI/FAPAR datasets allowing the global estim…

2012

Publish or perish. This saying clearly exemplifies that science communication is vital for scientists, research bodies and nation competitiveness. Nowadays both computers and internet have deeply changed the way scientific articles are written and published. In an editorial world moving at accelerated pace, scientists are eager to get their papers published in the best journals because impact factors are ruling careers and funding. Since fundings are provided by various public and private bodies, scientific papers should be partly understandable by a wide audience from journalists to entrepreneurs, political leaders and the general public. However, as an editor of scientific journals, I obs…
