Comparative Effectiveness Analysis of Phase 3 Clinical Trials in Moderately to Severely Active Inflammatory Bowel Disease Reveals Increased Harm From Placebo and Challenges Equipoise

JCC Plus, Volume 1, Issue 5, September 2026.
Across 47 Phase 3 trials in Crohn's disease and ulcerative colitis, placebo exposure was associated with measurable harm. Disease exacerbation events showed the greatest excess risk, with one additional exacerbation occurring for every 8–13 patients assigned to placebo rather than active therapy.

Advancing Circular Strategies in Photovoltaics: Assessing Reuse Readiness Across Technical, Economic, and Environmental Dimensions in a Case Study

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1077-1099, September 2026.
This study examines the reuse readiness of photovoltaic modules through the Swiss PV Circle project. Results confirm technical feasibility with cost savings from targeted preselection, whereas economic viability depends on module age, testing, and market conditions.

QUEST: Quasar unsupervised encoder and synthesis tool

Astronomy & Astrophysics
Context. Quasars at the redshift frontier ( z > 7.0) are fundamental probes of black hole growth and evolution, but are notoriously difficult to identify. At these redshifts, machine-learning-based selection methods have proven to be efficient, but require appropriate ...

Direct Ink Writing of Geopolymer Composites Reinforced With Polypropylene Fibers

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT Polypropylene fiber (PPf) reinforced geopolymer inks were systematically optimized for extrusion‐based additive manufacturing through regulation of ink composition, rheological parameters, nozzle size, and fiber content. The effects of polyethylene glycol (PEG) content and H2O to K2O ratio on printability were investigated.

Characterizing electronic noise interference from the external laser positioning system on a radiation therapy MRI simulation scanner

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Magnetic resonance imaging (MRI) for radiation therapy treatment planning is currently being used in many anatomical sites to better visualize soft tissue landmarks, a technique known as an MRI simulation. A core component of modern MRI simulation configurations are the use of external laser positioning systems (ELPS) to help set up

Dark energy black holes with intermediate masses at high redshifts: An earlier generation of quasars and observations

Modern Physics Letters A, 2023
Dark energy is the largest fraction of the energy density of our universe — yet it remains one of the enduring enigmas of our times. Here we show that dark energy can be used to solve 2 tantalizing mysteries of the observable universe. We build on existing models of dark energy linked to neutrino masses.

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

Advanced Materials, Volume 38, Issue 45, 13 August 2026.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation

Advanced Science, Volume 13, Issue 48, 28 August 2026.
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

Optimizing over Multiple Distributions under Generalized Quasar-Convexity Condition

Advances in Neural Information Processing Systems 37
We study a typical optimization model where the optimization variable is composed of multiple probability distributions. Though the model appears frequently in practice, such as for policy problems, it lacks specific analysis in the general setting.
