Utopia Remembers: The Soviet Past in the Imagined Communist Future

The Russian Review, EarlyView.
Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

Einstein Doubly Warped Product Poisson Manifolds

In this paper, we study Einstein doubly warped product Poisson manifolds. First, we provide necessary and sufficient conditions for a doubly warped product manifold (M=Bf×bF,g,Π), equipped with a Poisson structure Π to be a contravariant ...

An international study on emerging arboviral infections and blood safety

Transfusion, EarlyView.
Abstract Background Emerging and re‐emerging arboviral infections are a risk to blood safety. We conducted an international survey on how blood establishments respond to current and future arbovirus threats. Study Design and Methods A questionnaire on arbovirus donor deferral strategies, pathogen reduction, and donation screening was distributed to ...

Coupling between global brain blood oxygen level‐dependent activity and cerebrospinal fluid dynamics in young endurance athletes

Experimental Physiology, EarlyView.
Abstract Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes

Coarse Sediment Transport in a Near‐Terminus Subglacial Channel

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We present the first large‐sample, spatially resolved measurements of coarse sediment transport within a subglacial meltwater channel. We released 324 radio‐tagged pebbles into a near‐terminus channel of Glacier d’Otemma, Switzerland, and monitored their positions through 10–50 m of ice during the mid to late melt season.

Novel Theorems on Spacetime Admitting Pseudo-W2 Curvature Tensor

Journal of Mathematics
This paper investigates spacetime manifolds admitting a pseudo-W2 curvature tensor. We show that a pseudo-W2 flat spacetime is an Einstein manifold and therefore has constant curvature.

Contradicting Kuhn's Popular Notion of Scientific Revolution: Conservative Revolutionaries in the History of Biology

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT Proposing the concept of a conservative revolutionary generally and using the examples of Gregor Mendel, Max Delbrück, and Eric Davidson, I fundamentally call into question Thomas Kuhn's ideas of scientific revolutions. I also highlight some problematic consequences of the increasing appreciation of Kuhn's work among scientists and show that ...

Artificial Creativity and Human Fragility

Modern Theology, Volume 42, Issue 3, Page 543-558, July 2026.
Abstract This article critiques the widespread assumption that generative AI systems exhibit genuine artistic creativity. While such systems can produce novel and aesthetically appealing outputs, assessments based solely on results obscure fundamental differences between human and artificial agents.

A Data‐Driven Multiscale Scheme for Anisotropic Finite Strain Magneto‐Elasticity

International Journal for Numerical Methods in Engineering, Volume 127, Issue 12, 30 June 2026.
ABSTRACT In this work, we develop a neural network‐based, data‐driven, decoupled multiscale scheme for the modeling of structured magnetically soft magnetorheological elastomers (MREs). On the microscale, sampled magneto‐mechanical loading paths are imposed on a representative volume element containing spherical particles and an elastomer matrix, and ...

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.
