Tunable X-ray dark-field imaging for sub-resolution feature size quantification in porous media
X-ray computed micro-tomography typically involves a trade-off between sample size and resolution, complicating the study at a micrometer scale of representative volumes of materials with broad feature size distributions (e.g. natural stones). X-ray dark-field tomography exploits scattering to probe sub-resolution features, promising to overcome this trade-off. In this work, we present a quantific
INTERATRIAL BLOCK
Criteria for diagnosing atrial blockade, which is manifested on the electrocardiogram by lengthening and changing the morphology of wave P, are examined. The prognostic value of far-reaching atrial blockade as a predictor of the development of supraventricular arrhythmias and embolic stroke is discussed.
Dimensions of corruption in Pakistan : A systems thinking approach and qualitative analysis
Over the past few decades, many studies of corruption have been carried out. These studies have mainly focused on specific aspects of corruption such as economic issues, legal issues, social propositions, national development and economic policy. This study builds a systems thinking model of corruption, which helps in the understanding of corruption and acts as an input into future policymaking on
Researching the virtual : A framework for reflexivity in qualitative social media research
Recent years have seen an explosion in social media in our everyday lives, and a corresponding increase in social media research in IS. As social media researchers, we are intrigued by the problem of virtuality and context in social media research, and how we might apply reflexive research principles to such settings. In social media, the absence of a setting's real physical boundaries (to a large
Template-free generation and integration of functional 1D magnetic nanostructures
The direct integration of 1D magnetic nanostructures into electronic circuits is crucial for realizing their great potential as components in magnetic storage, logical devices, and spintronic applications. Here, we present a novel template-free technique for producing magnetic nanochains and nanowires using directed self-assembly of gas-phase-generated metallic nanoparticles. The 1D nanostructures
The lifecycle impact and value capture of circular business models in the built environment
Circular economy (CE) has been of utmost interest in the industry and research community in the preceding years. However, CE is still a nascent research field in the built environment context. As technological advances within CE are slowing, the incorporation of business models into the concept is deemed important to achieve the necessary transition. Circular business models within the built envir
Probing proton structure with c c ¯ correlations in ultraperipheral pA collisions
We study the exclusive diffractive cc¯ photoproduction in ultraperipheral pA collisions. The formalism makes use of off-diagonal generalizations of the unintegrated gluon distribution, the so-called generalized transverse momentum dependent distributions (GTMDs). We present two different formulations. The first one is based directly on gluon GTMD parametrizations in momentum space. Another option
Into the Trading Book: Estimating Expected Shortfall
In light of the revised 2019 proposals constituting the Fundamental Review of the Trading Book, which amend the third Basel Accord, expected shortfall is set to replace value at risk as the risk measure dictating banks' capital reserving requirements for exposure to market risk. This paper examines how best to accurately estimate expected shortfall from a regulatory perspective by carrying out
Sin Stocks: An Analysis of the Sin Premium in the US, European, and Asia-Pacific Markets
This thesis aims to explain the return of so-called sin stocks, which include businesses operating in the alcohol, tobacco, gambling, weapon, and oil & gas industries. Due to their negative public perception, these stocks are anticipated to yield a sin premium. This study analyses the potential variation of sin premiums across three different markets, specifically the US, European, and Asia-Pa

Delivery of acute ischaemic stroke treatments in the European region in 2019 and 2020
Introduction: We assessed best available data on access and delivery of acute stroke unit (SU) care, intravenous thrombolysis (IVT) and endovascular treatment (EVT) in the European region in 2019 and 2020. Patients and methods: We compared national data per number of inhabitants and per 100 annual incident first-ever ischaemic strokes (AIIS) in 46 countries. Population estimates and ischaemic stro
Direct CEP Stabilization of a high-repetition rate, few-cycle OPCPA chain with a single feedback loop, employing a Stereo-ATI
Today's Carrier-Envelope Phase (CEP) stabilizations of mode-locked oscillators widely used in attosecond science and frequency metrology rely on octave spanning frequency combs and the detection of beating between the blue end and the frequency doubled red end of the same spectrum. This technique was established by the seminal works of Hänsch and co-workers [1], demonstrating the stabilization of

Serum selenium concentrations in patients with autoimmune thyroiditis and non-toxic nodular goiter
Selenium (Se) deficiency is said to contribute to the atrophy of the thyroid gland in certain endemic goiter areas in Africa. To test the hypothesis that, a low Se intake could protect against goiter development in autoimmune thyroiditis, we analysed the Se concentration in 20 patients with the atrophic variant of lymphocytic thyroiditis, 23 patients with Hashimoto's thyroiditis and 23 patients wi

Blockchain Technology for Enhancing Sustainable Food Systems: A Consumer Perspective
This paper explores the potential of blockchain technology (BCT) in promoting sustainable food production and consumption (SFPC) from a consumer perspective. India, a significant global food producer, faces challenges related to affordability and food logistics due to transport and labour constraints. Food safety concerns, i.e., foodborne illnesses and quality issues, alongside unexpected events l
