Nonparametric Specification Testing for Nonlinear Time Series with Nonstationarity [PDF]

open access: yes
This paper considers a nonparametric time series regression model with a nonstationary regressor. We construct a nonparametric test for testing whether the regression is of a known parametric form indexed by a vector of unknown parameters.

Healing Integrity Determines Meniscal Extrusion After Isolated Medial Meniscus Posterior Root Repair in Knees With No Lower Limb Malalignment

open access: yesArthroscopy, EarlyView.
Purpose To investigate changes in meniscal extrusion and meniscal healing status following root repair, and the relationship between meniscal extrusion and healing conditions. Methods Patients who underwent isolated root repair between 2019 and 2023 and consented to undergo second‐look arthroscopy to evaluate their healing condition (1 year ...

Nonparametric quantile regression captures regional variability and scaling deviations in Atlantic surfclam length–weight relationships

open access: yesScientific Reports
The universality of the allometric model for describing the length–weight relationship in marine species has been questioned, particularly for some invertebrates such as sea urchins, clams, and barnacles.

Computed Tomography‐Based Morphometric Analysis Reveals Intercondylar Notch Stenosis and Osteophytes Are Associated With Anterior Cruciate Ligament Injury

open access: yesArthroscopy, EarlyView.
Purpose To quantitatively assess intercondylar notch morphometrics using 3‐dimensional computed tomography reconstruction, evaluate their association with anterior cruciate ligament (ACL) injury in Asian populations, and investigate the prevalence of osteophytes in patients with ACL injury.

Nonparametric Regression with Spatially Dependent Data [PDF]

open access: yes, 2009
In this paper we present a new procedure for nonparametric regression in case of spatially dependent data. In particular, we modify the two-step local linear regression of Martins-Filho and Yao (2009) by introducing information on spatial dependence via ...

Small but Significant Effect on Patellar Height and Tibial Tuberosity‐Trochlear Groove Distance Following Ascending Versus Descending Tibial Tubercle Osteotomy in Medial Open‐Wedge High Tibial Osteotomy

open access: yesArthroscopy, EarlyView.
Purpose To compare radiographic patellofemoral characteristics following ascending tibial tubercle (AT) and descending tibial tubercle (DT) medial open‐wedge high tibial osteotomy (OWHTO). Methods This retrospective single‐center study included all patients who underwent AT‐OWHTO or DT‐OWHTO between October 2014 and December 2022 with complete ...

Testing a parametric quantile-regression model with an endogenous explanatory variable against a nonparametric alternative [PDF]

open access: yes, 2009
This paper is concerned with inference about a function g that is identified by a conditional quantile restriction involving instrumental variables. The paper presents a test of the hypothesis that g belongs to a finite-dimensional parametric family ...

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

open access: yesAnimal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Effects of Dietary Mannan Oligosaccharides on Growth, Disease Resistance, and Gut Microbiota in Zebrafish

open access: yesAnimal Research and One Health, EarlyView.
Supplementation with mannan oligosaccharides (MOS) enhances growth, disease resistance, antioxidant capacity, and gut microbiota diversity while suppressing inflammation, apoptosis, and strengthening intestinal barrier integrity in zebrafish challenged with LPS or DSS.
