Spatially Resolved Local Electronic Properties of 2D Lead Halide Perovskite Single Crystals Studied by X-Ray Photoemission Electron Microscopy

Recently, research on the edge states of 2D lead halide perovskites (LHPs) has been attracting much attention. The lower-energy edge state (LES) is believed to provide an efficient pathway for the dissociation of photoexcited excitons. However, the mechanism of the LES formation remains controversial, and studies that establish precisely the local electronic properties are lacking. Herein, the fir

Szegő Type Asymptotics for the Reproducing Kernel in Spaces of Full-Plane Weighted Polynomials

Consider the subspace Wn of L2(C, dA) consisting of all weighted polynomials W(z)=P(z)·e-12nQ(z), where P(z) is a holomorphic polynomial of degree at most n- 1 , Q(z) = Q(z, z¯) is a fixed, real-valued function called the “external potential”, and dA=12πidz¯∧dz is normalized Lebesgue measure in the complex plane C. We study large n asymptotics for the reproducing kernel Kn(z, w) of Wn; this depend

Reliability of estimating left ventricular ejection fraction in clinical routine : a validation study of the SWEDEHEART registry

Objective: Patients hospitalized with acute coronary syndrome (ACS) in Sweden routinely undergo an echocardiographic examination with assessment of left ventricular ejection fraction (LVEF). LVEF is a measurement widely used for outcome prediction and treatment guidance. The obtained LVEF is categorized as normal (> 50%) or mildly, moderately, or severely impaired (40–49, 30–39, and < 30%, respect

Rare Siblings Speed-Up Deterministic Detection and Counting of Small Pattern Graphs

We consider a class of pattern graphs on q≥ 4 vertices that have q- 2 distinguished vertices with equal neighborhood in the remaining two vertices. Two pattern graphs in this class are siblings if they differ by some edges connecting the distinguished vertices. In particular, we show that if induced copies of siblings to a pattern graph in such a class are rare in the host graph then one can detec

THE HUMAN SIDE OF THE BANKS’ CREDIT MANAGEMENT OF SMALL FIRMS-A Cognitive Approach to Corporate Evaluation

The human side of corporate evaluation is frequently neglected in small firm and credit management research. However, it seems to matter both who is being evaluated, especially in smaller companies, and who is making the evaluation. A major reason is that individuals process information in different ways. The purpose of this paper is to develop a conceptual framework for the effects of human diffe

The use of lectures : effective pedagogy or seeds scattered on the wind?

This case study of large-class teaching at a UK university focuses on the place of large-scale lectures in academics’ approaches to teaching, their use by students in their studies, and their relationship to institutional quality assurance policies. The case is a second-year module comprised of 180 students, and it includes two-hour lectures as the primary mode of teaching. The data is drawn from

Conceptualising the Cosmos : Development and Validation of the Cosmology Concept Inventory for High School

Cosmology concepts encompass complex spatial and temporal relations that are counterintuitive. Cosmology findings, because of their intrinsic interest, are often reported in the public domain with enthusiasm, and students come to cosmology with a range of conceptions some aligned and some at variance with the current science. This makes cosmology concepts challenging to teach, and also challenging

Investigation of Thermoluminescence Properties of Li2B4O7 : Ag, Cu, Ni Nano-Composites

The present paper explores the TL characteristics of Ag, Cu and Ni doped and co-doped Li2B4O7 nano-composites (NCs). These NCs were synthesized via a Sol–gel process. The influence of doping agents on the optical and TL properties of Li2B4O7 NCs was investigated. Obtained nano-composites were calcined at 700 °C for 8 h. The incorporation of Ag, Cu and Ni impurities in Li2B4O7 lattice has been conf

Fusion rules in a Majorana single-charge transistor

A demonstration of the theoretically predicted non-abelian properties of Majorana bound states (MBSs) would constitute a definite proof of a topological superconducting phase. Alongside the nontrivial braiding statistics, the fusion rules are fundamental properties of all non-abelian anyons. In this work, we propose and theoretically analyze a way to demonstrate MBS fusion rules in a Majorana sing

SHIPBROKING AND CHARTERING PRACTICE, SEVENTH EDITION

Shipbroking and Chartering Practice provides a sound knowledge of the law and economics of international shipbroking and chartering in a practical way that enables the principles described to be applied in everyday situations. The seventh edition has been thoroughly revised to take account of chartering practices, cases and standard forms that have surfaced since the last edition, providing an exc

Hybrid modelling of water resource recovery facilities : status and opportunities

Mathematical modelling is an indispensable tool to support water resource recovery facility (WRRF) operators and engineers with the ambition of creating a truly circular economy and assuring a sustainable future. Despite the successful application of mechanistic models in the water sector, they show some important limitations and do not fully profit from the increasing digitalisation of systems an

Carrying out long-term search and rescue missions, intelligence, surveillance and reconnaissance, which are carried out with the help of unmanned aerial vehicles (UAVs), overload the operator and reduce the effectiveness of solving the assigned tasks, up to the point of making their implementation impossible. The paper proposes the concept of increasing the speed of the human-machine system based

Swedish public and private housing companies’ access to the capital market for financing energy renovation

The financing of energy efficiency measures and renovations is key to reaching energy efficiency targets for the housing sector. The purpose of this article is to add the Swedish case of how capital market funds have become accessible and used by public and private housing companies, in particular for energy efficiency measures. The core of this article are interviews with representatives of Swedi

Atrial fibrillation episode patterns as predictor of clinical outcome of catheter ablation

Methods for characterization of atrial fibrillation (AF) episode patterns have been introduced without establishing clinical significance. This study investigates, for the first time, whether post-ablation recurrence of AF can be predicted by evaluating episode patterns. The dataset comprises of 54 patients (age 56 ± 11 years; 67% men), with an implantable cardiac monitor, before undergoing the fi

Leading with a cool head and a warm heart : trait-based leadership resources linked to task performance, perceived stress, and work engagement

Leaders of today need to achieve well in terms of task performance, perceiving low stress, and having high levels of work engagement. One may ask whether trait-based leadership resource factors can be identified and how such resource factors might relate to task performance, perceived stress, and work engagement. Our aim was to test the hypothesis, derived from Hobfoll’s motivational Conservation

Considerations on the Systematics of Neotropical Pierina, with the Description of Two New Species of Phulia Herrich-Schäffer from the Peruvian Andes (Lepidoptera: Pieridae, Pierinae, Pierini)

A comparative analysis of high-Andean Pierina was carried out, including a total of 25 species. Based on morphological evidence, with an emphasis on venation and genitalia and molecular data, using three genetic markers, we confirm the recent subjective synonymy of the generic names Tatochila Butler, 1870, Piercolias, Staudinger, 1894, Hypsochila Ureta, 1955, Infraphulia Field, 1958, Pierphulia Fi

Enterococcus faecalis bacteremia, cardiac implantable electronic device, extraction, and the risk of recurrence

Purpose: In all patients with cardiac implantable electronic devices (CIED) and Enterococcus faecalis bacteremia (EfsB), endocarditis (IE) and CIED infection should be suspected. Guidelines recommend extraction of the CIED when CIED infection or IE is diagnosed. Whether extraction of the CIED should be done in other situations with EfsB is not known. We aimed to describe the management and outcome
