Probing Majorana localization in minimal Kitaev chains through a quantum dot

Artificial Kitaev chains, formed by quantum dots coupled via superconductors, have emerged as a promising platform for realizing Majorana bound states. Even a minimal Kitaev chain (a quantum dot-superconductor-quantum dot setup) can host Majorana states at discrete sweet spots. However, unambiguously identifying Majorana sweet spots in such a system is still challenging. In this work, we propose a

Tree cover and its heterogeneity in natural ecosystems is linked to large herbivore biomass globally

Addressing intertwined crises of climate change and biodiversity loss is a pressing global challenge, with trees playing pivotal roles in promoting carbon sequestration and habitat diversity. However, there is a distinct knowledge gap concerning the global drivers shaping tree cover and its heterogeneity, particularly the roles and relative importance of large herbivores and fire compared to clima

Multimodal classification of molecular subtypes in pediatric acute lymphoblastic leukemia

Genomic analyses have redefined the molecular subgrouping of pediatric acute lymphoblastic leukemia (ALL). Molecular subgroups guide risk-stratification and targeted therapies, but outcomes of recently identified subtypes are often unclear, owing to limited cases with comprehensive profiling and cross-protocol studies. We developed a machine learning tool (ALLIUM) for the molecular subclassificati

Fermion mass hierarchy in an extended left-right symmetric model

We present a Left-Right symmetric model that provides an explanation for the mass hierarchy of the charged fermions within the framework of the Standard Model. This explanation is achieved through the utilization of both tree-level and radiative seesaw mechanisms. In this model, the tiny masses of the light active neutrinos are generated via a three-loop radiative inverse seesaw mechanism, with Di

Switchable Broadband Terahertz Absorbers Based on Conducting Polymer-Cellulose Aerogels

Terahertz (THz) technologies provide opportunities ranging from calibration targets for satellites and telescopes to communication devices and biomedical imaging systems. A main component will be broadband THz absorbers with switchability. However, optically switchable materials in THz are scarce and their modulation is mostly available at narrow bandwidths. Realizing materials with large and broa

Recent patent-based review on the role of three-dimensional printing technology in pharmaceutical and biomedical applications

Three-dimensional printing (3DP) is emerging as an innovative manufacturing technology for biomedical and pharmaceutical applications, since the US FDA approval of Spritam as a 3D-printed drug. In the present review, we have highlighted the potential benefits of 3DP technology in healthcare, such as the ability to create patient-specific medical devices and implants, as well as the possibility of

Creating Shia Spaces in British Society : The Role of Transnational Twelver Shia Networks in North-West London

Scholarship addressing Shia Muslim minorities in Western contexts often refers to them as a ‘minority within a minority’ or ‘the other within the other,’ highlighting their dual-marginalization within non-Muslim societies. This paper challenges the concept of double-marginalization by examining the dynamics of transnational Shia communal spaces in north-west London and the creation of Shia spaces

Head-to-head comparison of two loop-mediated isothermal amplification (LAMP) kits for diagnosis of malaria in a non-endemic setting

Background: Light microscopy and rapid diagnostic tests (RDT) have long been the recommended diagnostic methods for malaria. However, in recent years, loop-mediated isothermal amplification (LAMP) techniques have been shown to offer superior performance, in particular concerning low-grade parasitaemia, by delivering higher sensitivity and specificity with low laboratory capacity requirements in li

Camouflage efficiency in a colour-polymorphic predator is dependent on environmental variation and snow presence in the wild

Colour polymorphism can be maintained by colour morph-specific benefits across environmental conditions. Currently, the amount and the duration of snow cover during winter decrease especially in northern latitudes, which can alter the potential for camouflage of animals with light and dark morphs. Tawny owls, Strix aluco, are colour-polymorphic avian predators with dark (brown) and light (grey) co

Technological Innovation Adoption Among Swedish Healthcare Professionals : A Contingency Technology Adoption Framework

Technological innovation adoption by healthcare professionals directly impacts enhanced patient care and overall community well-being. However, the perspective of healthcare professionals in evaluating and adopting these technological innovations should be addressed. Drawing on innovation adoption and resistance theories, in this article, we aim to capture their perceptions of the barriers they fa

Engaging consumers through artificially intelligent technologies: Systematic review, conceptual model, and further research

While consumer engagement (CE) in the context of artificially intelligent (AI-based) technologies (e.g., chatbots, smart products, voice assistants, or autonomous cars) is gaining traction, the themes characterizing this emerging, interdisciplinary corpus of work remain indeterminate, exposing an important literature-based gap. Addressing this gap, we conduct a systematic review of 89 studies usin

Utility of heparin-binding protein following cardiothoracic surgery using cardiopulmonary bypass

Cardiothoracic surgery using cardiopulmonary bypass (CPB) triggers an inflammatory state that may be difficult to differentiate from infection. Heparin-binding protein (HBP) is a candidate biomarker for sepsis. As data indicates that HBP normalizes rapidly after cardiothoracic surgery, it may be a suitable early marker of postoperative infection. We therefore aimed to investigate which variables i

Selection despite low genetic diversity and high gene flow in a rapid island invasion of the bumblebee, Bombus terrestris

Invasive species are predicted to adjust their morphological, physiological and life-history traits to adapt to their non-native environments. Although a loss of genetic variation during invasion may restrict local adaptation, introduced species often thrive in novel environments. Despite being founded by just a few individuals, Bombus terrestris (Hymenoptera: Apidae) has in less than 30 years suc

A Paradigm Shift in the Management of Patients with Parkinson's Disease

Background: Technological evolution leads to the constant enhancement of monitoring systems and recording symptoms of diverse disorders. Summary: For Parkinson's disease, wearable devices empowered with machine learning analysis are the main modules for objective measurements. Software and hardware improvements have led to the development of reliable systems that can detect symptoms accurately and

Teuvoahtiana meridionalis, a new species from Patagonia and Antarctica

The new species Teuvoahtiana meridionalis is described from Antarctica and Southern South America. Even though the new species is morphologically and chemically variable, it is mo-lecularly monophyletic and located in the genus Teuvoahtiana in the subfamily Xanthorioideae. The genetic variation could not be correlated to the variation in any other characters that could support any further division

THz Spectroscopic Electron Paramagnetic Resonance of the Fe3+Defect in GaN

We present a recently developed method for electron paramagnetic resonance (EPR) measurements in the THz spectral range. The method is based on spectroscopic ellipsometry and thus requires no cavity, unlike conventional EPR. This permits us to scan the frequency parameters in addition to the magnetic field parameters. To showcase this, both frequency and magnetic field scans are performed on Fe-do

Diversity and relationships between Andean shrubland puna butterflies in the genus Punargentus (Lepidoptera: Nymphalidae: Satyrinae)

Two new species and two new subspecies of the satyrine butterfly genus Punargentus Heimlich, P. atusparia sp. n., P. heimlichi sp. n., P. blanchardi libertas ssp. n. and P. atusparia yupania ssp. n., are described from north-central Peru (Ancash, Huánuco and La Libertad). The affinities of the new taxa are evaluated based on molecular data obtained using target enrichment and COI barcoding. Punarg

Twenty years on from the introduction of the high risk strategy for stroke and cardiovascular disease prevention : a systematic scoping review

Background and purpose: Early this century, the high risk strategy of primary stroke and cardiovascular disease (CVD) prevention for individuals shifted away from identifying (and treating, as appropriate) all at-risk individuals towards identifying and treating individuals who exceed arbitrary thresholds of absolute CVD risk. The public health impact of this strategy is uncertain. Methods: In our
