Nonprojective Bell-state measurements

The Bell-state measurement (BSM) is the projection of two qubits onto four orthogonal maximally entangled states. Here we first propose how to appropriately define more general BSMs, which have more than four possible outcomes, and then study whether they exist in quantum theory. We observe that nonprojective BSMs can be defined in a systematic way in terms of equiangular tight frames of maximally

RipD (Rv1566c) from mycobacterium tuberculosis : Adaptation of an NlpC/p60 domain to a non-catalytic peptidoglycan-binding function

Enzymes carrying NlpC/p60 domains, for instance RipA and RipB from Mycobacterium tuberculosis, are bacterial peptidoglycan hydrolases that cleave the peptide stems and contribute to cellwall remodelling during cell division.Amember of this protein family, RipD (Rv1566c) from M. tuberculosis described in the present study, displays sequence alterations in the NlpC/p60 catalytic triad and carries a

Enhanced classification performance using deep learning based segmentation for pulmonary embolism detection in CT angiography

Purpose: To develop a deep learning-based algorithm that automatically and accurately classifies patients as either having pulmonary emboli or not in CT pulmonary angiography (CTPA) examinations. Materials and methods: For model development, 700 CTPA examinations from 652 patients performed at a single institution were used, of which 149 examinations contained 1497 PE traced by radiologists. The n

Quantitative flow ratio will supplant wire-based physiological indices : pros and cons

Quantitative flow ratio (QFR) represents a physiological index derived from angiography through three-dimensional (3D) quantitative coronary analysis. When compared to coronary angiography, QFR showed better performance both for guiding percutaneous coronary intervention (PCI) in case of intermediate coronary lesions and for optimising PCI results. In addition, QFR showed good diagnostic agreement

Microbiome–metabolite linkages drive greenhouse gas dynamics over a permafrost thaw gradient

Interactions between microbiomes and metabolites play crucial roles in the environment, yet how these interactions drive greenhouse gas emissions during ecosystem changes remains unclear. Here we analysed microbial and metabolite composition across a permafrost thaw gradient in Stordalen Mire, Sweden, using paired genome-resolved metagenomics and high-resolution Fourier transform ion cyclotron res

Grain alignment in hexaferrite permanent magnets by compaction at room and elevated temperatures

Shape-controlled precursors enable grain alignment without using an applied magnetic field in the permanent magnet material strontium hexaferrite. The effect is investigated by conducting four series of experiments using different compaction methods: two cold and two hot compactions. The hypothesis is that magnetic short-circuiting will diminish the grain alignment (texture) in cold compacted samp

Intensive early and sustained lowering of non–high-density lipoprotein cholesterol after myocardial infarction and prognosis : the SWEDEHEART registry

Background and Non–HDL-C provides an estimate of lipid-associated risk and is a secondary treatment target after myocardial infarction Aims (MI). The aim was to study the relationship between non–HDL-C levels after MI and risk of adverse outcomes. Methods From the SWEDEHEART registry, 56 262 patients with MI were included. Outcomes were major adverse cardiovascular event (MACE: death, MI, and isch

Review article : Drought as a continuum – memory effects in interlinked hydrological, ecological, and social systems

Droughts are often long-lasting phenomena, without a distinct start or end and with impacts cascading across sectors and systems, creating long-term legacies. Nevertheless, our current perceptions and management of droughts and their impacts are often event-based, which can limit the effective assessment of drought risks and reduction of drought impacts. Here, we advocate for changing this perspec

Gene Therapy with Fidanacogene Elaparvovec in Adults with Hemophilia B.

Background Fidanacogene elaparvovec, an adeno-associated virus (AAV) gene-therapy vector for hemophilia B containing a high-activity human factor IX variant (FIX-R338L/FIX-Padua), was associated with sustained factor IX activity in a phase 1-2a study. Methods We conducted a phase 3 open-label study of fidanacogene elaparvovec at a dose of 5×1011 vector genome copies per kilogram of body weight. Me

Modified Nucleic Acid Extraction Protocol for Humic-Rich Permafrost Peat Samples v1

Slight modifications to the manufacturer’s protocol (Qiagen #12966-10, now discontinued and replaced with #12988-10) enabled the successful extraction of high-quality DNA and RNA from permafrost peat samples. Integrating the DNA and RNA purification steps immediately after the extraction process helped streamline the workflow, resulting in consistent quality nucleic acids suitable for downstream s

Transfer learning reconstructs submarine topography for global mid-ocean ridges

Mid-ocean ridges are unique, tectonically active geographical units on Earth that profoundly control the ocean environment and dynamics at the global scale. However, high-resolution topographic data from mid-ocean ridges are rarely available due to the difficulty in detecting ocean floors, which further limits ocean research at the global scale. Here, we divide the global mid-ocean ridge system in

Challenges in the practical implementation of blood biomarkers for Alzheimer's disease

Blood biomarkers have emerged as accessible, cost-effective, and highly promising tools for advancing the diagnostics of Alzheimer's disease. However, transitioning from cerebrospinal fluid biomarkers to blood biomarkers—eg, to verify amyloid β pathology—requires careful consideration. This Series paper highlights the main challenges in the implementation of blood biomarkers for Alzheimer's diseas

Fluid biomarkers in the context of amyloid-targeting disease-modifying treatments in Alzheimer's disease

Clinical management and therapeutics development for Alzheimer's disease (AD) have entered a new era, with recent approvals of monoclonal antibody therapies targeting the underlying pathophysiology of the disease and modifying its trajectory. Imaging and fluid biomarkers are becoming increasingly important in the clinical development of AD therapeutics. This review focuses on the evidence of fluid

Evaluation of data quality in the Swedish National Penile Cancer Register

Objective: The National Penile Cancer Register (NPECR) in Sweden was initiated in year 2000 and currently contains more than 3,900 men diagnosed with penile cancer. The aim of this study was to evaluate data quality in the NPECR in terms of completeness, timeliness, comparability, and validity. Material and methods: Completeness was assessed by cross-linkage to the Swedish Cancer Register. Timelin

Virus ecology and 7-year temporal dynamics across a permafrost thaw gradient

Soil microorganisms are pivotal in the global carbon cycle, but the viruses that affect them and their impact on ecosystems are less understood. In this study, we explored the diversity, dynamics, and ecology of soil viruses through 379 metagenomes collected annually from 2010 to 2017. These samples spanned the seasonally thawed active layer of a permafrost thaw gradient, which included palsa, bog

Diversity in IPCC author’s composition does not equate to inclusion

The IPCC holds the gold standard for climate change scientific knowledge and authority at the science–policy interface. Here we reflect on our experience of the IPCC Sixth Assessment Report and discuss how diversity in authorship and inclusion of different disciplinary backgrounds can be improved.

The Infinite Body

The Drawing of Our Lives in Berlin 2007-2022 (2022) and Narrating our Lines (2010) for the group exhibition 'The infinite body' at Ramat Gan Museum of Israeli Art, plan b are showing an installation combining two existing works - a large scale drawing and a video work.

Enhancing Autonomous Vehicles System Security : Advanced Attack Detection for Robust Safeguarding

The advances in highly automated and autonomous transportation systems over the last decade have generated great interest in topics in the safe navigation of land vehicles. With distributed control strategies employed in the majority of applications of autonomous vehicles, such as traffic and formation control, the much-required resilience takes the form of fault-tolerance with respect to informat
