Isotonic Regression by Dynamic Programming.

, 2019
For a given sequence of numbers, we want to find a monotonically increasing sequence of the same length that best approximates it in the sense of minimizing the weighted sum of absolute values of the differences. A conceptually easy dynamic programming approach leads to an algorithm with running time O(n log n).

Electromyography and sonomyography analysis of the tibialis anterior: a cross sectional study

Journal of Foot and Ankle Research, 2014
Background Foot dorsiflexion plays an essential role in both controlling balance and human gait. Electromyography (EMG) and sonomyography (SMG) can provide information on several aspects of muscle function.

Happiness and Smell: Overlooked Factors in Endoscopic Sinus Surgery?

Clinical Otolaryngology, Volume 51, Issue 4, Page 585-590, July 2026.
ABSTRACT Objective This study investigates the impact of functional endoscopic sinus surgery (FESS) on happiness levels in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and examines the factors influencing postoperative happiness. Methods This study included 55 patients (34 males, 21 females; mean age, 41.2 ± 14.7 years) who underwent

Machine learning algorithms for prediction of cerebrospinal fluid leakage after posterior surgery for thoracic ossification of the ligamentum flavum

Scientific Reports
To develop and validate a machine-learning (ML) model that pre-operatively predicts cerebrospinal-fluid leakage (CSFL) after posterior decompression for thoracic ossification of the ligamentum flavum (TOLF), and to elucidate the key risk factors driving ...

Isotonic Distributional Regression

, 2022
Distributional regression estimates the probability distribution of a response variable conditional on covariates. The estimated conditional distribution comprehensively summarizes the available information on the response variable, and allows to derive all statistical quantities of interest, such as the conditional mean, threshold exceedance ...

Isotonic regression on permutations

, 1996
Motivated by an approach to qualifying potential judges, we study isotonic regression problems on a partially ordered set of permutations. We consider the partial orders discussed in Block, Chhetry, Fang and Sampson (1990) which are used for comparing the dependence of bivariate empirical distributions with fixed marginals. We give a method to generate
