EVSS‐Based Simulation Techniques for the Viscoelastic Fluids With Pure Polymer Melts Using Three‐Field Approach

International Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 492-509, April 2026.
This paper presents a finite element method for simulating highly viscoelastic flows of pure polymer melts using the Elastic Viscous Stress Splitting formulation. The method avoids higher‐order derivatives in the weak formulation by reformulating the convective term in the constitutive equation.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Global Spatial and Temporal Variability of the Oceanic Cool Skin Effect

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The oceanic cool skin effect is characterized by a temperature depression between the ocean's submillimeter thermal skin layer (SSTskin) and the underlying water (SSTdepth). This study evaluates the ability of the widely used Fairall et al. (1996), https://doi.org/10.1029/95jc03190 model (F96) to simulate the cool skin effect using surface ...

A Phenoregion Approach to Understanding Chlorophyll‐a Seasonal Cycles and Interannual Variability in the South‐West Indian Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The South‐West Indian Ocean (SWIO) displays marked spatial variations in physical forcings, driving in turn distinct seasonal biogeochemical regimes. Mesoscale eddies in the Mozambique Channel drive large‐scale redistribution of nutrients and plankton, while eastern Madagascar waters are highly oligotrophic.

Diabetes Mellitus is a Risk Factor for Hepatic Encephalopathy Following Transjugular Intrahepatic Portosystemic Shunt

Alimentary Pharmacology &Therapeutics, Volume 63, Issue 7, Page 967-978, April 2026.
Diabetes mellitus independently increases the risk of hepatic encephalopathy following TIPS placement in patients with cirrhosis. These findings emphasize the need for careful risk assessment in patients with cirrhosis and portal hypertension complications undergoing TIPS.

Print Conventions and Authority in Three English Recipe Manuscripts

Renaissance Studies, Volume 40, Issue 2, Page 231-253, April 2026.
Abstract This article considers the uses of stylistic and visual conventions drawn from print books in three seventeenth‐ and eighteenth‐century recipe manuscripts at the University of Pennsylvania. We begin by analysing the title page, dedicatory epistle, catchwords, and headers of MS Codex 627, which imitates an edition of Hugh Plat's Delights for ...

Investigating innovative optical solitons for a (3+1)- dimensional nonlinear Schrödinger’s equation under the influences of 4th-order dispersive and parabolic law of nonlinearities

Results in Optics
This study tackles a nonlinear Schrödinger’s equation in three dimensions, using three dispersive components of fourth order, often resulting in pure-quartic solitons.

Bifurcation Analysis of a Resource–Consumer System With Explicit Spatiotemporal Memory

Studies in Applied Mathematics, Volume 156, Issue 4, April 2026.
ABSTRACT In ecological systems, animal movement is often influenced by memory and spatial cognition, especially in advanced species. This paper investigates the dynamics of a diffusive resource–consumer model incorporating explicit spatiotemporal distributed memory, where memory effects are modeled as distributed delays in both time and space.

Natural top quark condensation (a redux)

Nuclear Physics B
The Nambu–Jona-Lasinio (NJL) model involves a pointlike 4-fermion interaction. While it gives a useful description of chiral dynamics (mainly in QCD), it nonetheless omits the crucially important internal wave-function of a two-body bound state, ϕ(r ...

Existence and Spectral Stability Analysis of Viscous‐Dispersive Shock Profiles for Isentropic Compressible Fluids of Korteweg Type

Studies in Applied Mathematics, Volume 156, Issue 4, April 2026.
ABSTRACT The system describing the dynamics of a compressible isentropic fluid exhibiting viscosity and internal capillarity in one space dimension and in Lagrangian coordinates, is considered. It is assumed that the viscosity and the capillarity coefficients are nonlinear smooth, positive functions of the specific volume, making the system the most ...
