Myelodysplastic syndromes (MDS) are heterogeneous clonal hematological disorders characterized by ineffective hematopoiesis resulting in peripheral cytopenias. Luspatercept, an erythroid maturation agent, represents a novel therapeutic option for the management of anemia associat...

Off-fault plasticity limits the speed of elongated earthquake ruptures
Summary Conventional earthquake rupture models in elastic media with scale-independent dissipation predict rupture acceleration up to a limiting speed dictated by seismic wave speeds. However, most earthquakes are inferred to be significantly slower than these theoretical limitin...

Probing near-surface potentials with the self-binding threshold of dipolar quantum droplets
Abstract Self-bound quantum droplets formed by strongly magnetic atoms are a platform for quantum metrology experiments. Here, we form a theoretical framework wherein external potentials generated in the interior of a hollow cylinder can be observed via modification of the format...

Abstract JuRa, the Juventas Radar, is the sounding radar of the Hera/ESA mission on cruise to the asteroid Didymos and its moon, Dimorphos. In 2027, it will, for the first time, do direct observation of the internal structure of an asteroid for the benefit of both science and pla...

Deployed quantum key distribution network: further, longer and more users
Abstract Entanglement-based quantum links are intended to become the backbone of future quantum networks, enabling secure communication between distant cities. Implementing such networks requires addressing multiple practical challenges: time synchronization, interferometric syst...

Building on Social Identity Theory (SIT), the dimensional compensation model (DCM) suggests that people rely on the Big Two dimensions of social evaluation to manage their group identity: members of low (high) status groups compensate their relative lower (higher) standing compet...

This article introduces the concept of the cognitive divide to describe the gap between societies, organizations, or sectors that are able to retain control over the conditions under which cognitive functions are integrated into, used through, and externalized to AI systems, and...

Radiative Transfer with Partially Frequency Coherent Scattering
We consider a spectral line formed with a linear combination of monochromatic scattering and complete frequency redistribution. A previous theoretical and numerical investigation by Hemsch and Ferziger in 1971 and 1972 suggests that a very small percentage of complete frequency r...

Understanding positive affect in Angelman syndrome: Smiling and laughter across comparison groups
Angelman syndrome (AS) is a neurogenetic condition marked by frequent smiling and laughter. Early descriptions portrayed these expressions as inappropriate or disconnected from context, but recent work has questioned this view. This study examined the emotional responses of child...

Abstract Background Advances in high-fidelity long-read (HiFi-LR) sequencing technologies have opened new opportunities to explore the microbial genomic diversity of complex environments, such as soils. While short-read (SR) sequencing has enabled broad insights at the gene level...

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...

Abstract Non-Hermitian photonics provides a framework to engineer the gain and loss of optical modes in open systems, enabling the control of their spectral and dynamical properties. In particular, the ability to dynamically tune modal losses offers a route to implement functiona...

STARSFLUX: an all-sky catalogue of absolute spectro-photometric calibrators from 0.3 to 30 μ m
Abstract Obtaining accurate fluxes of faint sources from the ground in near- and mid-infrared wavelengths is challenging because of the rapidly changing atmospheric absorption. A common limitation is the lack of a nearby spectro-photometric calibrator. We present the STellar Abso...
