LEGO: A tool to improve problem solving and teamwork skills of students in science

The aim of the present research is to compare problem solving and teamwork skills of the students that benefit from the educational Lego and the traditional method of teaching in science in third grade of elementary school in Tabriz. Therefore, in a quasi-experimental study using pre-test and post-test with control group, 40 students were selected randomly and placed in two groups- experimental and control- (learning by Lego and traditional method). In order to equalize the members of groups the student's GPA were controlled and pre-test and IQ test has been done. Before implementing the LEGO, for experimental and control groups, problem solving and teamwork pre-tests were used. The experimental group was exposed to the independent variable and the control group was taught through the classical teaching methods which currently used in the country and finally, both groups were exposed to problem-solving and teamwork post-tests. The results showed that the student's problem solving and teamwork skills, that benefit from the educational Lego was much more than who used traditional methods

Follow-up CMR in a case of Loeffler endocarditis

The typical finding of hypereosinophilic syndrome (Eosinophilic myocarditis) in the delayed enhancement (DE) cardiac magnetic resonance (CMR) is the �double V� sign, which includes (a) normal myocardium, (b) thickened enhanced endomyocardial layer, and (c) overlying apical thrombus. Corticosteroids may result in significant improvement of myocardial involvement. © 2020 The Authors. Clinical Case Reports published by John Wiley & Sons Lt

Multi-partite entanglement and quantum phase transition in the one-, two-, and three-dimensional transverse field Ising model

In this paper we consider the quantum phase transition in the Ising model in the presence of a transverse field in one, two and three dimensions from a multi-partite entanglement point of view. Using \emph{exact} numerical solutions, we are able to study such systems up to 25 qubits. The Meyer-Wallach measure of global entanglement is used to study the critical behavior of this model. The transition we consider is between a symmetric GHZ-like state to a paramagnetic product-state. We find that global entanglement serves as a good indicator of quantum phase transition with interesting scaling behavior. We use finite-size scaling to extract the critical point as well as some critical exponents for the one and two dimensional models. Our results indicate that such multi-partite measure of global entanglement shows universal features regardless of dimension $d$. Our results also provides evidence that multi-partite entanglement is better suited for the study of quantum phase transitions than the much studied bi-partite measures.Comment: 7 pages, 8 Figures.

A Comparison of the effectiveness of cooperative and individual teaching methods on educational achievement of English in grade one of high school

The purpose of this study was to compare cooperative teaching and individual teaching on educational achievement in English in grade one of high school (female students). This study is a quasi-experimental study with pre-test- and post- test with two experimental groups. The Statistical population was high school's first grade female students of Mahabad. For sampling, multi-stage cluster sampling was used. The sample size was 52 consist of 25 and 27 members in the experimental group (1) and (2) in which cooperation and individual teaching methods were used respectively. In order to equalize the members of groups the student's GPA were controlled and pre-test and IQ test were done. The results showed no significant difference between groups.The pre-test was a researcher-made. Reliability of the pre-test was obtained 0.83. The cooperative and individual methods were done for 2 months and then post- test was carried out. The results showed no significant differences between them. T-test analyzes shows significant differences between the two groups so that the first experimental group (cooperative) showed better performance in educational achievement

Adiabatic entanglement transport in Rydberg aggregates

We consider the interplay between excitonic and atomic motion in a regular, flexible chain of Rydberg atoms, extending our recent results on entanglement transport in Rydberg chains [W\"uster et al., Phys.Rev.Lett 105 053004 (2010)]. In such a Rydberg chain, similar to molecular aggregates, an electronic excitation is delocalised due to long range dipole-dipole interactions among the atoms. The transport of an exciton that is initially trapped by a chain dislocation is strongly coupled to nuclear dynamics, forming a localised pulse of combined excitation and displacement. This pulse transfers entanglement between dislocated atoms adiabatically along the chain. Details about the interaction and the preparation of the initial state are discussed. We also present evidence that the quantum dynamics of this complex many-body problem can be accurately described by selected quantum-classical methods, which greatly simplify investigations of excitation transport in flexible chains

An adult case with absence of left pulmonary artery and partial anomalous pulmonary venous connection: Case report and literature review

Unilateral absence of pulmonary artery is a rare congenital disorder that can remain asymptomatic until adulthood. Absence of left pulmonary artery (ALPA) has been reported in one-third of these patients. We are the first to introduce an adult case of ALPA associated with partial anomalous pulmonary venous connection. © 2021 The Authors. Clinical Case Reports published by John Wiley & Sons Ltd
