Ray-tracing-assisted High-Resolution Parameter Estimation for Dynamic Millimeter-Wave Channels

An accurate description of the wireless channel is essential to the development of modern wireless systems. In order to mathematically model the propagation channel, one important prior step often done is high-resolution parameter estimation. The estimation accuracy of this step has a significant impact on how well the channel models can represent reality. In this paper, we address this by improvi

Radiation Efficiency and Gain Bounds for Microstrip Patch Antennas

This paper presents bounds on radiation efficiency and gain for microstrip patch antennas, demonstrating close alignment with the performance of classic antenna designs. These bounds serve as effective benchmarks for assessing antenna performance and evaluating trade-offs and design feasibility. The study particularly addresses the trade-off between miniaturization and performance by comparing bou

Rb-promoted Fe/CeO2 nanocatalyst for aniline conversion into azoxybenzene, DFT calculations and mechanism

Selectivity control of aniline oxidation and low reactant conversion in traditional synthesis methods are great challenges, and it is desirable to develop a green, low-cost and highly efficient catalytic route toward value-added products. Herein, an Rb-promoted Fe/CeO2 nanocatalyst was prepared to understand the effects of Rb-promoter on the catalytic performance for the selective oxidation of ani

Cancers not detected in one-view breast tomosynthesis screening—characteristics and reasons for non-detection

Objectives: Limited understanding exists regarding non-detected cancers in digital breast tomosynthesis (DBT) screening. This study aims to classify non-detected cancers into true or false negatives, compare them with true positives, and analyze reasons for non-detection. Materials and methods: Conducted between 2010 and 2015, the prospective single-center Malmö Breast Tomosynthesis Screening Tria

Self-reported physical activity more than 1 year after stroke and its determinants in relation to the WHO recommendations

BACKGROUND: Physical activity (PA) after stroke has significant health benefits if it is conducted regularly, with sufficient intensity and duration. Because of the health benefits, it is important to identify those below the World Health Organization (WHO) recommended level of PA. However, few studies have assessed the level of PA after stroke in relation to the WHO recommendations and which soci

Event-related theta synchronization over sensorimotor areas differs between younger and older adults and is related to bimanual motor control

When engaged in dynamic or continuous movements, action initiation involves modifying an ongoing motor program rather than initiating it from rest. Event-related theta synchronization over sensorimotor areas is a neurophysiological marker for modifying motor programs. We used electroencephalography (EEG) to examine how task complexity and age affect event-related synchronization (ERS) in the theta

Där litterärt språk möter läkarspråk : Litteraturens potential för undervisning i medicinsk humaniora

This article discusses how fiction and its collisions between different linguistic registers have both literary and pedagogical potential. Taking its point of departure in literary texts used in the medical humanities teaching at the medical school at Lund University, various types of collisions between literary language and medical language are analysed. To conceptualize the collisions between th

Integrative analyses of circulating microRNA expression profile in hexavalent chromium exposed workers - A cross-sectional study within the SafeChrom project

Background Exposure to hexavalent chromium (Cr(VI)) can occur during occupational activities and leading lung cancer. MicroRNA (miRNA) plays an important part in carcinogenesis. Whether Cr(VI) exposure causes cancer-related miRNA changes is yet uncharacterized. Methods This study included 89 Cr(VI) exposed workers and 47 controls. MiRNAs were extracted from plasma followed by library preparations,

Simmering Tensions and Emerging Conflicts Among Key Group Actors Amid Capitalist Transformation in Northern Ghana

A capitalist agrarian transformation is unfolding in northern Ghana, marked by shifts in crop types, rapid increases in farm sizes and deepening rural social differentiation. This paper investigates these dynamics through a mixed-methods approach across six farming communities in two districts, focusing on how social differentiation, accumulation, dispossession and exploitation reshape the region.

Contact Allergy to Methacrylate Containing Nail Products : Lack of Impact of EU Legislation. An Audit on Behalf of the European Environmental Contact Dermatitis Research Group (EECDRG)

Background: There is a current fashion for the use of methacrylate-containing nail cosmetics that can induce allergic contact dermatitis. European Union (EU) legislation was introduced in 2021 that had the aim of preventing its development. Objectives: To assess prevalence and exposures causing contact allergy to 2-hydroxyethyl methacrylate (HEMA) prior to and following implementation of the legis

Expectations and Sensemaking : Older People and Care Robots

We do not yet know how the robotization of eldercare will unfold, but one thing is clear: technology mediates human practices and experiences [1]. As such, care robots will co-shape the actions of care givers and older people and influence the perceptions and experiences of old age. The robotization of eldercare means that it is essential for developers, policy makers, and researchers to become in

Clinical Applications of Bone Marrow CD34 Immunohistochemistry (BM CD34 IHC) Assay : International Council for Standardization in Hematology (ICSH) Guidelines

Introduction: Investigation of bone marrow (BM) trephine biopsies and/or clot sections by CD34 immunohistochemistry (IHC) testing has been used by pathologists for several decades, and its clinical value has been well established with QBEND10 being the most frequently used primary antibody (Ab) clone. However, most other parameters related to the IHC protocol as well as the readout vary widely bet
