The capabilities of ultrasound optical tomography (UOT) is investigated through Monte Carlo simulations on realistic breast tissue phantoms constructed using the OpenVCT platform. This work indicates that UOT is a method capable of distinguishing malignant tumor tissue from benign glandular tissue deep inside the breast, despite the natural variations of adipose and glandular compartments within a

Quantum memories for quantum communication need to be able to store photons for an extended time and then to release them on demand. This can be achieved in atomic frequency comb ensemble-based quantum memories by control pulses that transfer the excitation to and from long-lived spin states. However, such pulses can give rise to coherent and incoherent noise due to their interaction with the memo

Remote sensing observations and artificial intelligence algorithms have emerged as key components for crop yield estimation at various scales during the past decades. However, the utilization of multi-source satellite data and machine learning for estimating aggregated crop yield at the regional level in Europe has been only scarcely explored. Our study aims to bridge this research gap by focusing

Background: Four reports, published in the form of pre-prints or peer-reviewed articles, have recently described that spinocerebellar ataxia type 4 (SCA4) is caused by expansion of GGC repeats in exon 10 of ZFHX3 . None of the independent reports have definitely established if longer repeats are associated with earlier disease onset.Methods: We compiled clinical and genetic data from all four publ

Background: Combined movement disorders often represent a diagnostic challenge. Dystonia is a movement disorder characterized by genetic and clinical heterogeneity. A recurring p.(Glu303del)-deletion in TOR1A is a well-established cause for DYT-TOR1A (DYT1) dystonia. TOR1A encodes TorsinA, an AAA+ ATPase located in the nuclear envelope. Hemichorea-hemiballismus syndrome can occur after basal gangl

Objective To elucidate experiences and coping strategies among adults in the surveillance of indeterminate pulmonary nodules detected with CT in the population-based Swedish CardioPulmonary bioImage Study (SCAPIS).Design A qualitative study of conventional content analysis.Settings The study was conducted at a university hospital in a southern region of Sweden. The SCAPIS setting is similar to the

Background: The incidence of lower urinary tract infection (LUTI) in men visiting primary health care (PHC) is low. Hence, GPs do not diagnose and treat men with LUTI very often. Previous studies have shown that adherence to treatment guidelines regarding LUTI in men is low. There is limited knowledge concerning why guidelines are not adhered to.Aim: To gain knowledge on GPs’ experiences and conceBackground: The incidence of lower urinary tract infection (LUTI) in men visiting primary healthcare (PHC) is low.

Coking is a common catalyst deactivation route in industrial processes involving carbonaceous species. While coking is easy to diagnose, this is often performed by bulk analysis. Understanding specific symptoms such as pore blockage and obstruction of active sites is especially challenging for technical catalysts and requires a spatially-resolved approach. Here a combination of ptychographic X-ray

The widespread availability of large language models (LLMs) has presented the opportunity for novice programmers to make use of them for the purpose of understanding and synthesising code. In this paper, we discuss a small pilot study intended to explore the user experience of doing so in a limited way, and the attitudes of a group of novice programmers towards this style of programming. We also d

This study explores the implementation of a complementary currency – an alternative approach to addressing the problem of poverty caused by the scarcity of conventional money. Complementary currencies can be defined as agreement within communities to use something different to a national currency as a standardized medium of exchange. Previous research has examined the various classifications and o

The terms ‘informal sector’ and ‘shadow economy’ are in vogue but remain conceptually fuzzy in what they measure or mean. They are used in tax research and policy but with many assumptions, leading to poorly designed policies that lead to further immiseration of those who derive their livelihoods informally. Focusing on Sub-Saharan Africa, I critically interrogate the current conceptualisation of

Organizations are viewed as ordered places that legitimizes the hand that holds back, and that formalizes structured, institutionalized ways of saying and doing. Against this backdrop, we want to see the more recent attention to the entrepreneurial as a reason to conceptualize the new organization that emerges from within the existing organization as the “other organization,” accomplished through
