A Human Kidney Tubuloid Model of Repeated Cisplatin‐Induced Cellular Senescence and Fibrosis for Drug Screening

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 7, 16 February 2026.
Replicating aging and senescence‐related pathophysiological responses in kidney organoids remains a significant challenge. Human adult renal tubular organoid, tubuloids, are successfully developed recapitulating cellular senescence that is the central pathophysiological mechanism of chronic kidney disease (CKD).

Eliminating Spurious Velocities with a Stable Approximation of Viscous Incompressible Two-Phase Stokes Flow

open access: yes, 2013
We present a parametric finite element approximation of two-phase flow. This free boundary problem is given by the Stokes equations in the two phases, which are coupled via jump conditions across the interface.

Directed Navigation of Magnetotactic Bacteria via Magnetotaxis in a 3D Vasculature‐On‐A‐Chip

open access: yesAdvanced Materials Technologies, Volume 11, Issue 4, 19 February 2026.
A perfusable vascular network is developed to investigate MTB at the single‐microorganism level. MTB is demonstrated to successfully align and navigate along the magnetic field inside the microvessels. Abstract Magnetotactic bacteria (MTB), inherently motile and self‐powered, are promising biorobotic candidates for targeted anti‐cancer drug delivery ...

Gap solitons of a super-Tonks-Girardeau gas in a one-dimensional periodic potential

open access: yes, 2012
We study the stability of gap solitons of the super-Tonks-Girardeau bosonic gas in one-dimensional periodic potential. The linear stability analysis indicates that increasing the amplitude of periodic potential or decreasing the nonlinear interactions ...

Indirect Inference for Locally Stationary Models

open access: yes, 2020
We propose the use of indirect inference estimation to conduct inference in complex locally stationary models. We develop a local indirect inference algorithm and establish the asymptotic properties of the proposed estimator.

Observations on degenerate saddle point problems

open access: yes, 2007
We investigate degenerate saddle point problems, which can be viewed as limit cases of standard mixed formulations of symmetric problems with large jumps in coefficients. We prove that they are well-posed in a standard norm despite the degeneracy.

Masses, luminosities, and orbital coplanarities of the µ Orionis quadruple-star system from phases differential astrometry [PDF]

open access: yes, 2008
μ Orionis was identified by spectroscopic studies as a quadruple-star system. Seventeen high-precision differential astrometry measurements of μ Ori have been collected by the Palomar High-precision Astrometric Search for Exoplanet Systems (PHASES ...

XMM-Newton observations of three short period polars: V347 Pav, GG Leo and EU UMa

open access: yes, 2003
We present phase-resolved XMM_Newton data of three short period polars: V347 Pav, GG Leo and EU UMa. All three systems show one dominant accretion region which is seen for approximately half of the orbital cycle.

Black-body components in Gamma-Ray Bursts spectra?

open access: yes, 2007
We study 7 Gamma Ray Bursts (GRBs), detected both by the BATSE instrument, on-board the Compton Gamma Ray Observatory, and by the Wide Field Camera (WFC), on-board BeppoSAX.

Too Litter, Too Late: Economic Logistics of Transporting Nutrient-Rich Poultry Litter Out of Nutrient-Saturated Regions [PDF]

open access: yes
Export of excess litter from concentrated animal production regions has become a pressing issue. A break even price for poultry litter in nutrient-deficient areas was identified through a math programming model using willingness to pay data from crop ...
