Stable Cuts, NAC‐Colourings and Flexible Realisations of Graphs

Journal of Graph Theory, Volume 113, Issue 3, Page 411-427, November 2026.
ABSTRACT A (2‐dimensional) realisation of a graph G is a pair ( G , p ), where p maps the vertices of G to R 2. A realisation is flexible if it can be continuously deformed while keeping the edge lengths fixed, and rigid otherwise. We say that G is rigid if every generic realisation of G is rigid; otherwise, G is flexible. In this paper, we investigate

On the affine analogue of Jack and Macdonald polynomials

Duke Mathematical Journal, 1995
The authors study the Jack symmetric polynomials and their generalizations for affine Lie algebras and quantum groups. They first prove that the Jack symmetric polynomials for the (generalized) root system \(A_{n-1}\) with root multiplicity \(k\) can be defined as trace of an intertwining operator. More exactly, let \(\lambda\) be a dominant weight and

Patient Information and Surgery Decisions: A Discrete Choice Experiment

Health Economics, Volume 35, Issue 10, Page 1571-1596, October 2026.
ABSTRACT Surgical treatments are offered more widely than ever before, increasingly to older and high‐risk patients. However, it is unclear whether patients making surgical decisions are fully informed about the risks of surgery and the available non‐surgical treatments.

Non-commutative creation operators for symmetric polynomials

European Physical Journal C: Particles and Fields
We reconsider in modern terms the old discovery by A. Kirillov and M. Noumi, who devised peculiar operators adding columns to Young diagrams enumerating the Schur, Jack and Macdonald polynomials.

Deep learning auto‐contouring of target and organs‐at‐risk on post‐catheter implant CT images for prostate HDR brachytherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Accurate delineation of the prostate and surrounding organs‐at‐risk (OARs) is essential for HDR prostate brachytherapy. Manual contouring on post‐catheter CT images is time‐consuming and prone to variability due to artifacts and anatomical deformation from the implanted brachytherapy catheters.

Kenyan Farmers' Policy Priorities During Economic Crisis and Stability: Insights From a Best‐Worst Scaling Experiment

Applied Economic Perspectives and Policy, Volume 48, Issue 4, Page 820-833, September 2026.
ABSTRACT Amid rising food and fertilizer prices, understanding farmers' policy preferences is critical for effective crisis response. We use best‐worst scaling experiment to assess Kenyan mobile‐owning crop farmers' preferences for government support under high and normal price scenarios.

Rapid Quantitative Determination of Enantiomeric Excess by Vibrational Circular Dichroism Using Noise Based Spectral Selection

Chirality, Volume 38, Issue 9, September 2026.
Rapid VCD‐based determination of enantiomeric excess in limonene is achieved using signal‐to‐noise guided spectral selection and multivariate modeling. While 30‐min spectra provide high accuracy, 5‐min acquisitions retain ~97% performance, enabling faster throughput and offering a practical approach for rapid, reliable chiral analysis in applications ...

Jack polynomials and some identities for partitions [PDF]

Transactions of the American Mathematical Society, 2004
We prove an identity about partitions involving new combinatorial coefficients. The proof given is using a generating function. As an application we obtain the explicit expression of two shifted symmetric functions, related with Jack polynomials. These quantities are the moments of the “

Nonparametric Assessment of the Calibration of Individualized Treatment Effects

Statistics in Medicine, Volume 45, Issue 20-22, September 2026.
ABSTRACT An important aspect of the performance of algorithms that predict individualized treatment effects (ITEs) is moderate calibration, that is, the average treatment effect among individuals with predicted treatment effect of z being equal to z. The assessment of moderate calibration is a challenging task on two fronts: counterfactual responses ...
