Complete subvarieties of moduli spaces and the Prym map

, 2004
We prove that in characteristic p>0 the locus of stable curves of p-rank at most f is pure of codimension g-f in the moduli space of stable curves. Then we consider the Prym map and analyze it using tautological classes. We study the locus of curves with

Single‐molecule validation and optimised protocols for the use of secondary nanobodies in multiplexed immunoassays

Journal of Microscopy, Volume 301, Issue 3, Page 422-436, March 2026.
Abstract Recently developed secondary nanobodies or single‐domain antibodies present a powerful tool for immunodetection. Unlike traditional antibodies, their monovalence enables pre‐association with primary antibodies prior to sample staining, presenting a straightforward affinity‐based antibody labelling solution.

A new approach to pointwise heat kernel upper bounds on doubling metric measure spaces [PDF]

, 2013
On doubling metric measure spaces endowed with a strongly local regular Dirichlet form, we show some characterisations of pointwise upper bounds of the heat kernel in terms of global scale-invariant inequalities that correspond respectively to the Nash ...

Traceable Refractive Index Measurements of Liquids to Standardize Extracellular Vesicle Flow Cytometry

Cytometry Part A, Volume 109, Issue 2, Page 115-123, February 2026.
ABSTRACT Extracellular vesicles (EVs) are potential disease biomarkers released by cells into body fluids. Flow cytometers measure EV concentrations within their size detection range. These size ranges can be quantified by relating the arbitrary units of measured light scattering signals to the optical diameter of EVs with Mie theory.

Pólya's conjecture for Dirichlet eigenvalues of annuli

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We prove Pólya's conjecture for the eigenvalues of the Dirichlet Laplacian on annular domains. Our approach builds upon and extends the methods we previously developed for disks and balls. It combines variational bounds, estimates of Bessel phase functions, refined lattice point counting techniques and a rigorous computer‐assisted analysis. As

Non-unitary quantum many-body dynamics using the Faber polynomial method

SciPost Physics
Efficient numerical methods are still lacking to probe the unconventional dynamics of quantum many-body systems under non-unitary evolution. In this work, we use Faber polynomials to numerically simulate both the dynamics of non-Hermitian systems and the

Cholesteryl Fatty Acid Esters and Free Cholesterol in Food of Animal Origin

European Journal of Lipid Science and Technology, Volume 128, Issue 1, January 2026.
Cholesterol occurs in free (bioavailable) and esterified (transport/storage) forms. Here, we present a method that allows both forms to be determined independently. Finally, the quantities of free and esterified cholesterol were determined in several meat, animal fat, and cheese samples.

Faber Polynomial Coefficient Estimates for Subclass of Analytic Bi-Bazilevic Functions Defined by Differential Operator

مجلة بغداد للعلوم, 2019
In this work,  an explicit formula for a class of Bi-Bazilevic univalent functions involving differential operator is given, as well as the determination of upper bounds for the general Taylor-Maclaurin coefficient of a functions belong to this class ...

SERSµDrop: A Platform to Study Cell–Cell Communication via SERS Imaging

Small, Volume 22, Issue 1, 2 January 2026.
SERSµDrop is a microdroplet‐based optofluidic platform that enables real‐time, multiplexed surface‐enhanced Raman spectroscopy (SERS) imaging of small extracellular vesicle‐mediated communication between individual breast cancer and stromal cells. By combining extracellular vesicles labeled with SERS tags, microdroplet confinement, and multivariate ...
