Minimally Dissipative Information Erasure in a Quantum Dot via Thermodynamic Length
In this Letter, we explore the use of thermodynamic length to improve the performance of experimental protocols. In particular, we implement Landauer erasure on a driven electron level in a semiconductor quantum dot, and compare the standard protocol in which the energy is increased linearly in time with the one coming from geometric optimization. The latter is obtained by choosing a suitable metr
The cost-effectiveness of a uniform versus age-based threshold for one-off screening for prevention of cardiovascular disease
The objective of this article was to assess the cost-effectiveness of screening strategies for cardiovascular diseases (CVD). A decision analytic model was constructed to estimate the costs and benefits of one-off screening strategies differentiated by screening age, sex and the threshold for initiating statin therapy (“uniform” or “age-adjusted”) from the Spanish NHS perspective. The age-adjusted
Where did all the money go? Funding, personnel and expenditure in Swedish universities and colleges 2001–21
Swedish universities and colleges have received a substantial funding increase since the turn of the millennium, as part of continued policies of expanding the admission of students to higher education to broader layers of the population and strengthen Swedish public research and development to increase the competitiveness of the Swedish knowledge-based economy. In this article, publicly available
Applicability of the European Society of Cardiology Guidelines on the management of acute coronary syndromes to older people with haemophilia A – A modified Delphi consensus by the ADVANCE Working Group
Introduction: As people with haemophilia (PWH) receive better treatment and live longer they are more likely to encounter cardiovascular disease (CVD) and other comorbidities. ESC guidelines for the acute management of patients presenting with acute coronary syndrome (ACS) are based on the non-haemophilia population. Aim: To review the guidelines and propose relevant adaptations for PWHA without i
Prospects for Galactic transient sources detection with the Cherenkov Telescope Array
Several types of Galactic sources, like magnetars, microquasars, novae or pulsar wind nebulae flares, display transient emission in the X-ray band. Some of these sources have also shown emission at MeV-GeV energies. However, none of these Galactic transients have ever been detected in the very-high-energy (VHE; E>100 GeV) regime by any Imaging Air Cherenkov Telescope (IACT). The Galactic Transient
Rearing condition and willingness to approach a stranger explain differences in point following performance in wolves and dogs
The relative importance of adaptation and individual ontogenetic experience in dogs’ high levels of behavioral compatibility with humans has been a topic of intense scientific attention over the past two decades. Salomons et al. Current Biology, 31, 3137–3144, (2021) recently presented a particularly rich data set of observations on both wolf and dog puppies that has the potential to contribute su
Six Major Steps to Make Investigations of Suicide Valuable for Learning and Prevention
Objective: The decline in suicide rates has leveled off in many countries during the last decade, suggesting that new interventions are needed in the work with suicide prevention. Learnings from investigations of suicide should contribute to the development of these new interventions. However, reviews of investigations have indicated that few new lessons have been learned. To be an effective tool,
Exploring the population of Galactic very-high-energy γ-ray sources
At very high energies (VHE), the emission of γ rays is dominated by discrete sources. Due to the limited resolution and sensitivity of current-generation instruments, only a small fraction of the total Galactic population of VHE γ-ray sources has been detected significantly. The larger part of the population can be expected to contribute as a diffuse signal alongside emission originating from prop
Photoionization and core resonances from range-separated time-dependent density-functional theory for open-shell states : Example of the lithium atom
We consider the calculations of photoionization spectra and core resonances of open-shell systems using range-separated time-dependent density-functional theory. Specifically, we use the time-dependent range-separated hybrid (TDRSH) scheme, combining a long-range Hartree-Fock exchange potential and kernel with a short-range potential and kernel from a local density-functional approximation, and th
Cohort profile : Bladder Cancer Data Base Sweden (BladderBaSe) 2.0
PURPOSE: We constructed Bladder Cancer Data Base Sweden (BladderBaSe) 2.0 to expand studies in BladderBaSe on incidence, treatment outcomes, side effects, survival and health economic aspects of men and women with cancer in the urinary bladder, upper tract urothelial carcinoma (UTUC) (renal pelvis and ureter) and urethral carcinoma. PARTICIPANTS: BladderBaSe 2.0 includes 53 298 patients with cance
Real-world experience among patients with relapsed/refractory mantle cell lymphoma after Bruton tyrosine kinase inhibitor failure in Europe : The SCHOLAR-2 retrospective chart review study
Mantle cell lymphoma (MCL) after relapse is associated with poor prognosis. No standard of care exists and available evidence for treatments is limited, particularly in patients who fail Bruton tyrosine kinase inhibitor (BTKi) therapy. This multicentre retrospective chart review study, SCHOLAR-2, addresses this knowledge gap and reports on data collected from 240 patients with relapsed/refractory
Comparing algorithms for assessing upper limb use with inertial measurement units
The various existing measures to quantify upper limb use from wrist-worn inertial measurement units can be grouped into three categories: 1) Thresholded activity counting, 2) Gross movement score and 3) machine learning. However, there is currently no direct comparison of all these measures on a single dataset. While machine learning is a promising approach to detecting upper limb use, there is cu
Safeguarding the land to secure food in the highlands of Peru : The case of Andean peasant producers
Local or traditional agri-food systems in the Andes depend on community land use planning to maintain the genetic pool of crops and landraces in the face of disease, disasters, and climate change. These systems are managed integrally and on the basis of traditional knowledge around soil conservation, water management and maintaining biodiversity. At the same time, agri-food system research, policy
Longitudinal in vivo biodistribution of nano and micro sized hydroxyapatite particles implanted in a bone defect
Hydroxyapatite (HA) has been widely used as a bone substitute and more recently as a carrier for local delivery of bone targeted drugs. Majority of the approved HA based biomaterials and drug carriers comprise of micrometer sized particulate HA (mHA) or granules and can therefore only be used for extracellular drug release. This shortcoming could be overcome with the use of cell penetrating HA nan

Multiterminal transport spectroscopy of subgap states in Coulomb-blockaded superconductors
Subgap states are responsible for the low-bias transport features of hybrid superconducting-semiconducting devices. Here we analyze the local and nonlocal differential conductance of Coulomb-blockaded multiterminal superconducting islands that host subgap states with different spatial structures. The emerging patterns of their transport spectroscopy are used to characterize the possible topologica
Universality of charge doping driven metal-insulator transition in Sr2RhO4 and role of spin-orbit coupling
We performed angle-resolved photoemission spectroscopy (ARPES) experiments on an electron-doped Sr2RhO4 system Sr2-xCexRhO4 in order to investigate the electron doping-induced metal-insulator transition (MIT). We establish the universality of MIT in electron-doped Sr2RhO4 by comparing results from Sr2-xLaxRhO4 and Sr2-xCexRhO4. Via a systematic analysis of doping-dependent transport and ARPES data
Oxygen vacancies at the origin of pinned moments in oxide interfaces : The example of tetragonal CuO/SrTiO3
Obtaining an accurate theoretical description of the emergent phenomena in oxide heterostructures is a major challenge. Recently, intriguing paramagnetic spin and pinned orbital moments have been discovered by x-ray magnetic circular dichroism measurements at the Cu L2,3 edge of a tetragonal CuO/SrTiO3 heterostructure. Using first-principles calculations, we propose a scenario that explains both t
Inclusion of a cold hardening scheme to represent frost tolerance is essential to model realistic plant hydraulics in the Arctic-boreal zone in CLM5.0-FATES-Hydro
As temperatures decrease in autumn, vegetation of temperate and boreal ecosystems increases its tolerance to freezing. This process, known as hardening, results in a set of physiological changes at the molecular level that initiate modifications of cell membrane composition and the synthesis of anti-freeze proteins. Together with the freezing of extracellular water, anti-freeze proteins reduce pla
