Rehabilitation services for persons affected by stroke in Jordan

The purpose of this study was to explore the perceptions stroke survivors have of the rehabilitation services received by them in the Jordanian community. A secondary aim was to explore the impact of culture on providing appropriate services for stroke survivors.Eighteen stroke survivors were recruited from an outpatient stroke rehabilitation programme. All 18 participants had been discharged from hospital for between one and six months. Semi-structured interviews were performed, either in the physiotherapy outpatient clinic where the affected person was attending a clinic or in their homes. Transcription of interviews carried out in Arabic and thematic analysis was also carried out in that language by transcribers who were fluent in Arabic and English, using a back-translation method. Necessary measures were taken to ensure the accuracy, reliability and validity of the data collection and analysis. Following thematic analysis, themes arising out of the data included physiotherapy and occupational therapy support in the community, out-patient rehabilitation clinic services, community clinic services and support from families, friends and neighbours. Participants expressed satisfaction with their therapists, but there were large areas of unmet rehabilitation need for stroke survivors in the Jordanian community such as a limited availability of occupational therapy services, insufficient amount of therapy services and poor medical support.   This study presents a unique contribution to knowledge relating to the experiences of stroke survivors in a developing country, and also shows how care systems are very dependent on cultural contexts, cultural beliefs and practises.DOI 10.5463/DCID.v22i1.18</p

Analysis of the vector form factors fKπ+(Q2)f^+_{K\pi}(Q^2) and fKπ−(Q2)f^-_{K\pi}(Q^2) with light-cone QCD sum rules

In this article, we calculate the vector form factors $f^+_{K\pi}(Q^2)$ and $f^-_{K\pi}(Q^2)$ within the framework of the light-cone QCD sum rules approach. The numerical values of the $f^+_{K\pi}(Q^2)$ are compatible with the existing theoretical calculations, the central value of the $f^+_{K\pi}(0)$, $f^+_{K\pi}(0)=0.97$, is in excellent agreement with the values from the chiral perturbation theory and lattice QCD. The values of the $|f^-_{K\pi}(0)|$ are very large comparing with the theoretical calculations and experimental data, and can not give any reliable predictions. At large momentum transfers with $Q^2> 5GeV^2$, the form factors $f^+_{K\pi}(Q^2)$ and $|f^-_{K\pi}(Q^2)|$ can either take up the asymptotic behavior of $\frac{1}{Q^2}$ or decrease more quickly than $\frac{1}{Q^2}$, more experimental data are needed to select the ideal sum rules.Comment: 22 pages, 16 figures, revised version, to appear in Eur.

Quantum dynamics of phase transitions in broken symmetry λϕ4\lambda \phi^4 field theory

We perform a detailed numerical investigation of the dynamics of broken symmetry $\lambda \phi^4$ field theory in 1+1 dimensions using a Schwinger-Dyson equation truncation scheme based on ignoring vertex corrections. In an earlier paper, we called this the bare vertex approximation (BVA). We assume the initial state is described by a Gaussian density matrix peaked around some non-zero value of $$, and characterized by a single particle Bose-Einstein distribution function at a given temperature. We compute the evolution of the system using three different approximations: Hartree, BVA and a related 2PI-1/N expansion, as a function of coupling strength and initial temperature. In the Hartree approximation, the static phase diagram shows that there is a first order phase transition for this system. As we change the initial starting temperature of the system, we find that the BVA relaxes to a new final temperature and exhibits a second order phase transition. We find that the average fields thermalize for arbitrary initial conditions in the BVA, unlike the behavior exhibited by the Hartree approximation, and we illustrate how$$ and $$depend on the initial temperature and on the coupling constant. We find that the 2PI-1/N expansion gives dramatically different results for$$.Comment: 28 pages, 21 figures; ver 2 -- additional comments on the nature of the phase transition in 1+1 dimension

Highly-parallelized simulation of a pixelated LArTPC on a GPU

The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The algorithms have been written in Python and translated into CUDA kernels using Numba, a just-in-time compiler for a subset of Python and NumPy instructions. The GPU implementation achieves a speed up of four orders of magnitude compared with the equivalent CPU version. The simulation of the current induced on 10^3 pixels takes around 1 ms on the GPU, compared with approximately 10 s on the CPU. The results of the simulation are compared against data from a pixel-readout LArTPC prototype
