Benefiting from their ordered orientation and superior stability compared to traditional conjugated materials, hydrogen bonding (HB)-induced H-aggregates in organic small molecule hole-transport materials (HTMs) hold a big potential for high-performance inverted perovskite solar cells (IPSCs). However, H-aggregates can also lead to excessive face-aggregation by forming the gaps between aggregates,

The central complex (CX) is a highly conserved region of the insect brain, and its ubiquitous occurrence suggests that its neural circuits are of fundamental importance. While its overall layout has not changed since the evolution of insect flight, substantial variations exist in the internal organization of all CX components. By changing the details of a system of repeating columns and layers, th

We have investigated the optical properties of heterostructured InGaN platelets aiming at red emission, intended for use as nano-scaled light-emitting diodes. The focus is on the presence of non-radiative emission in the form of dark line defects. We have performed the study using hyperspectral cathodoluminescence imaging. The platelets were grown on a template consisting of InGaN pyramids, flatte

It has proven difficult to distinguish between topological Majorana bound states and nontopological Andreev bound states and to measure the unique properties of the former. In this work, we aim to alleviate this problem by proposing and theoretically analyzing a different type of fusion protocol based on transport measurements in a Majorana box coupled to normal leads. The protocol is based on swi

In this Perspective, we discuss thermal imbalance and the associated electron-mediated thermal transport in quantum electronic devices at very low temperatures. We first present the theoretical approaches describing heat transport in nanoscale conductors at low temperatures, in which quantum confinement and interactions play an important role. We then discuss the experimental techniques for genera

We report the real-valued static and complex-valued quasi-static anisotropic permittivity parameters of rare-earth scandate orthorhombic single crystal GdScO3 (GSO), TbScO3 (TSO), and DyScO3 (DSO). Employing continuous-wave terahertz spectroscopy (0.2-1 THz), the complex permittivity was extracted using an anisotropic ambient-film-ambient model. Data obtained from multiple samples of the same oxid

Wurtzite-type aluminum nitride (AlN) thin films exhibiting high thermal conductivity, large grain size, and low surface roughness are desired for both bulk acoustic wave and surface acoustic wave resonators. In this work, we use ammonia (NH3) assisted reactive sputter deposition of AlN to significantly improve these properties. The study shows a systematic change in the structural, thermal, and mo

This thesis focuses on design, processing and electro-optical investigations of two- and three-terminal photodetectors based on large arraysof around three million n+-i-n+ InP nanowires with embedded InAsP quantum heterostructures for broadband detection. The first part of thethesis work dealt with a general investigation of the room-temperature optoelectronic behavior of two-terminal photodetecto

A concept of germ graphs and the M-function formalism are employed to construct large families of isospectral and isoscattering graphs. This approach represents a complete departure from the original approach pioneered by Sunada, where isospectral graphs are obtained as quotients of a certain large symmetric graph. Using the M-function formalism and the symmetries of the graph itself we construct

Introduction Autistic persons experience problems with movements and body awareness in everyday functionality, expressed in affected movement quality. Yet, there is a knowledge gap about the effects of interventions targeting these aspects in autistic persons. Objective To evaluate effects of Basic Body Awareness Therapy (BBAT) and treatment-as-usual (TAU), compared to TAU alone on movement qualit

Polyunsaturated fatty acids (PUFA) have been shown to reduce liver fat compared to saturated fat, but effects of a novel “anti-lipogenic” diet replacing carbohydrates with PUFA (LCPUFA) or a low-fat healthy Nordic diet (HND) rich in whole-grains are unknown. The objective of this study was to investigate the effects of these diets, as compared with usual care (UC), on liver fat (primary outcome) a

Background: Wrist osteoarthritis can cause persistent pain, reduced joint mobility, and difficulty performing daily activities, negatively impacting quality of life. Although patient education and exercise therapy are recommended as first-line treatments for osteoarthritis in other joints, evidence supporting these strategies for wrist osteoarthritis remains limited. This randomized controlled tri

Two hydrogen-bonding monomers containing tetraethylene glycol (TEG) chains have been synthesized and characterized. The monomers are based on a bicyclic scaffold appended with either 4H-bonding benzyl-substituted ureidopyrimidinone motifs or 2H-bonding unsubstituted pyrrole-fused ureidopyrimidinone motifs, with the TEG chains introduced with the aim of developing amphiphilic monomers soluble in no

Somatostatin, produced by pancreatic islet δ cells, is a key intra-islet paracrine factor that regulates the secretion of the glucoregulatory hormones insulin and glucagon from β cells and α cells, respectively. Here, we show that glutamate and glucagon released by α cells cooperatively activate neighbouring δ cells through AMPA and glucagon receptors, thereby enabling spatiotemporal feedback cont

PURPOSE: Early administration of beta-lactam antibiotics is a crucial part in the treatment of sepsis and septic shock. Beta-lactams demonstrate time-dependent killing and therefore it is important to optimize the time above the minimal inhibitory concentration (MIC). An extra dose is recommended in threatening/suspected/confirmed septic shock. This study aimed to examine whether patients with sus

Electrospinning is a versatile technique for manufacturing micro-nano diameter fibers and has been used extensively for tissue engineering in vivo and advanced cell culture in vitro. Standard means of seeding cells onto such substrates typically offer no control over cell distribution, yielding dispersed, heterogeneous and low concentrations of cells. In this article, we investigate the viability

Light-emitting diodes (LEDs) are widely applied in fields ranging from solid-state lighting and high-resolution displays to optical communication and sensing. Despite their remarkable technological development, conventional thin-film LEDs remain constrained by strain-induced defects from lattice mismatch and restricted light extraction efficiency due to total internal reflection. Exploration of al

IntroductionForensic assessments of whether an injury would have been life-threatening often rely on empirical knowledge rather than evidence-based criteria. To address this gap, we applied the validated trauma scoring system New Injury Severity Score (NISS) to estimate mortality risk along the natural course of single stab injuries to the trunk.Methods and materialsWe included 408 survivors and 1
