Evaluating the Timing of Sitz Baths After Laser Hemorrhoidoplasty: An Exploratory Study

Health Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background Laser hemorrhoidoplasty (LHP) is a minimally invasive procedure for the treatment of hemorrhoids. Early sitz baths are recommended after conventional hemorrhoidectomy; however, their effectiveness following LHP has not been evaluated.

Another proof of the corona theorem

, 2022
Let $H^\infty(Δ)$ be the uniform algebra of bounded analytic functions on the open unit disc $Δ$, and let $\mathfrak{M}(H^\infty)$ be the maximal ideal space of $H^\infty(Δ)$. By regarding $Δ$ as an open subset of $\mathfrak{M}(H^\infty)$, the corona problem asks whether $Δ$ is dense in $\mathfrak{M}(H^\infty)$, which was solved affirmatively by L ...

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 ...

Interpolating sequences and the Toeplitz--Corona theorem on the symmetrized bidisk

Journal of Operator Theory, 2022
We characterize the interpolating sequences and prove a Toeplitz--Corona theorem in the setting of bounded holomorphic functions on the symmetrized bidisk.

Delayed Admission to the Intensive Care Unit Is Associated With Increased Mortality Risk in Critically Ill Patients: A Prospective Cohort Study

Journal of Advanced Nursing, Volume 82, Issue 9, Page 8646-8657, September 2026.
ABSTRACT Aim To examine the impact of delays in intensive care unit (ICU) admission on patient outcomes, specifically clinical deterioration and mortality among patients transferred from the emergency department (ED) or general wards following acute deterioration in an Australian public hospital.

The corona theorem for matrices

Mathematische Zeitschrift, 1989
Let F be an \(r\times k\)-matrix of bounded holomorphic functions in the unit disc such that the nonzero eigenvalues of \(FF^ *\) are bounded from below by some \(\delta >0\). We prove that there is a bounded holomorphic solution to \(Fu=g\) if g is an r-column of bounded holomorphic functions and the equation is solvable pointwise. If \(r=1\), this is

Overlap‐Weight Estimators With Machine‐Learned Plug‐Ins and Overlap‐Weight Targeted Maximum Likelihood Estimator

Biometrical Journal, Volume 68, Issue 4, August 2026.
ABSTRACT In estimating the average treatment effect (ATE), the plug‐in estimator with the efficient influence function and the targeted maximum likelihood estimator (TMLE) are semiparametrically efficient. However, the estimators suffer from the fact that too small/large a propensity score (PS) in the denominators can make the estimators unstable. This

Optimization Algorithm for Determining the Source Surface Radius Based on Parker Solar Probe In Situ Measurements From Encounters 1 to 19

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The Potential Field Source Surface (PFSS) extrapolation is a method for estimating the large scale coronal magnetic field from photospheric magnetograms. The source surface serves as the outer boundary of its solution domain, and is typically a spherical surface.

Shannon sampling based approach for the structural solution of nano‐objects by laboratory and synchrotron SAXS data

Journal of Applied Crystallography, Volume 59, Issue 4, Page 1170-1183, August 2026.
We present a model‐independent approach based on the Shannon sampling theorem to retrieve key structural parameters of proteins and core–shell micelles directly from small‐angle X‐ray scattering (SAXS) profiles. By bypassing the pair distribution function, the method overcomes q‐truncation artifacts and provides reliable mass, size and aggregation ...
