DNA methylation governs the sensitivity of repeats to restriction by the HUSH-MORC2 corepressor

The human silencing hub (HUSH) complex binds to transcripts of LINE-1 retrotransposons (L1s) and other genomic repeats, recruiting MORC2 and other effectors to remodel chromatin. How HUSH and MORC2 operate alongside DNA methylation, a central epigenetic regulator of repeat transcription, remains largely unknown. Here we interrogate this relationship in human neural progenitor cells (hNPCs), a soma

Power Analysis Through Simulations in STATA: A Step-by-Step Guide

You want to run an experiment where you anticipate finding a treatment effect.How large should your sample size be to have a reasonable chance of detectingsignificant results? In this manuscript, I present and explain the Stata code I use toaddress this question. The code uses simulations to conduct power analyses,offering a flexible alternative to the commonly used analytical tools. Unliketraditi

Holocene solar activity inferred from global and hemispherical cosmic-ray proxy records

Variations in solar activity have been proposed to play an important role in recent and past climate change. To study this link on longer timescales, it is essential to know how the Sun has varied over the past millennia. Direct observations of solar variability based on sunspot numbers are limited to the past 400 years, and beyond this we rely on records of cosmogenic radionuclides, such as 14C a

High-Speed Fluorescence Imaging Corroborates Biological Data on the Influence of Different Nozzle Types on Cell Spray Viability and Formation

Treating severe dermal disruptions often presents significant challenges. Recent advancements have explored biological cell sprays as a promising treatment, but their success hinges on efficient cell delivery and complete wound coverage. This requires a good spray distribution with a small droplet size, high particle number, and ample surface coverage. The type of nozzle used with the spray device

Unpacking Trust in International Intelligence Cooperation : SIGINT Trust Games in Denmark and Sweden

In recent years, trust has emerged as a topic of interest for scholars aiming to understand the mechanisms enabling transnational intelligence cooperation and focusing on relations of trust between intelligence agencies. The potential dynamics between the trust facilitating transnational intelligence cooperation and the public trust in intelligence agencies on a national level, however, remains un

Investigating the superconducting state of 2H−NbS2 as seen by the vortex lattice

2H-NbS2 is a classic example of an anisotropic multiband superconductor, with significant recent work focusing on the interesting responses seen when high magnetic fields are applied precisely parallel to the hexagonal niobium planes. It is often contrasted with its sister compound 2H-NbSe2 because they have similar onset temperatures for superconductivity, but 2H-NbS2 has no charge density wave w

Minding the body : A critical appraisal of three phenomenological accounts of embodiment in social work literature

Summary: In the few social work publications dedicated to exploring phenomenological philosophical concepts, embodiment or the lived body, promoted especially by phenomenologist Maurice Merleau-Ponty, seems to have received special attention. Roughly, and according to a phenomenological philosophical perspective, the lived body signifies a mind–body unity that is believed to constitute acts of hum

Real-Time Adaptive Anomaly Detection in Industrial IoT Environments

To ensure reliability and service availability, nextgeneration networks are expected to rely on automated anomaly detection systems powered by advanced machine learning methods with the capability of handling multi-dimensional data. Such multi-dimensional, heterogeneous data occurs mostly in todays Industrial Internet of Things (IIoT), where real-time detection of anomalies is critical to prevent To ensure reliability and service availability, nextgeneration networks are expected to rely on automated anomaly detection systems powered by advanced machine learning methods with the capability of handling multi-dimensional data.

Drug-resilient Cancer Cell Phenotype Is Acquired via Polyploidization Associated with Early Stress Response Coupled to HIF2α Transcriptional Regulation

Therapeutic resistance and recurrence remain core challenges in cancer therapy. How therapy resistance arises is currently not fully understood with tumors surviving via multiple alternative routes. Here, we demonstrate that a subset of cancer cells survives therapeutic stress by entering a transient state characterized by whole-genome doubling. At the onset of the polyploidization program, we ide

Laser Frequency Stabilization Using a Slow Light Cavity

Laser frequency stabilization is a necessary component in many modern technologies and physics experiments,providing spectral resolution for spectroscopic investigations, accurate optical clocks for timekeeping and phasestability for interferometry. The limiting factor to the frequency stability of state-of-the-art laser stabilization isfrequency uncertainty as a result from variations in the leng

Effect of patient specificity on predicting knee cartilage degeneration in obese adults : Musculoskeletal finite-element modeling of data from the CAROT trial

Obesity is a known risk factor for development of osteoarthritis (OA). Numerical tools like finite-element (FE) models combined with degenerative algorithms have been developed to understand the interplay between OA and obesity. In this study, we aimed to predict knee cartilage degeneration in a cohort of obese adults to investigate the importance of patient-specific information on degeneration pr

Baseline measurements in the assessment of ESS-specific radionuclide uptake by crops cultivated in Southern Sweden

The European Spallation Source, ESS, is a neutron research facility under construction in Lund, Southern Sweden. The Facility will produce neutrons by spallation, using a powerful linear accelerator to deliver protons to a tungsten target. In addition to the desired neutron production, a long list of radionuclides will be created as by-products of the nuclear reaction inside the target. The Swedis

A Complementary Multitechnique Approach to Assess the Bias in Molecular Weight Determination of Lignin by Derivatization-Free Gel Permeation Chromatography

The growing interest in lignin valorization in the past decades calls for analytical techniques for lignin characterization, ranging from wet chemistry techniques to highly sophisticated chromatographic and spectroscopic methods. One of the key parameters to consider is the molecular weight profile of lignin, which is routinely determined by size-exclusion chromatography; however, this is by no me

Stabilization versus competing de-metalation, trans-metalation and (cyclo)-dehydrogenation of Pd porphyrins at a copper surface

Metal-porphyrins are studied intensively due their potential applications, deriving from the variety of electronic and chemical properties, tunable by selecting metal centers and functional groups. Metalation, de- and trans-metalation processes are fundamental in this sense to investigate both the synthesis and the stability of these molecular building blocks. More specifically, Pd coordination in

Fermion-parity qubit in a proximitized double quantum dot

Bound states in quantum dots coupled to superconductors can be in a coherent superposition of states with different electron number but with the same fermion parity. Electrostatic gating can tune this superposition to a sweet spot, where the quantum dot has the same mean electric charge independent of its electron-number parity. Here, we propose to encode quantum information in the local fermion p
