Univariate Cubic L1 Interpolating Splines: Analytical Results for Linearity, Convexity and Oscillation on 5-PointWindows

open access: yesAlgorithms, 2010
We analytically investigate univariate C1 continuous cubic L1 interpolating splines calculated by minimizing an L1 spline functional based on the second derivative on 5-point windows.

A New Approach of Constrained Interpolation Based on Cubic Hermite Splines

open access: yesJournal of Mathematics, 2021
Suppose we have a constrained set of data and wish to approximate it using a suitable function. It is natural to require the approximant to preserve the constraints.

A Blood‐Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN‐Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1

open access: yesAdvanced Science, EarlyView.
Systemic platelet factor 4 (PF4) is significantly depleted in amyotrophic lateral sclerosis (ALS). Peripheral PF4 replenishment restores central proteostasis by driving OPTN‐dependent, PINK1‐independent selective autophagy in motor neurons. This intervention effectively clears toxic SOD1 aggregates, blunts glial activation, and preserves neuromuscular ...

A comparison of methods to adjust for continuous covariates in the analysis of randomised trials

open access: yesBMC Medical Research Methodology, 2016
Background Although covariate adjustment in the analysis of randomised trials can be beneficial, adjustment for continuous covariates is complicated by the fact that the association between covariate and outcome must be specified.

Preoperative FIB‐4 Index as a Potential Factor Associated With Severe Postoperative Complications and Endogenous Organ Failure After Hepatectomy for Hepatocellular Carcinoma

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study demonstrates that a preoperative FIB‐4 index ≥ 5.0 independently predicts severe complications and endogenous organ failure (EOF) following hepatectomy for hepatocellular carcinoma. By capturing structural liver fragility and systemic vulnerability, the FIB‐4 index enhances surgical risk stratification beyond traditional functional markers ...

Motion and Morphology Planning for Autonomous Manipulation in Clutter With a Shape‐Shifting, Variable‐Stiffness Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
A hybrid mobile robot with a modular Variable‐Stiffness Bridge transitions between a rigid locomotion platform and a flexible, shape‐conforming body. By enclosing objects within its deformable structure rather than relying on dedicated end effectors, the robot achieves orientation‐regulated planar transport, with conformal contact quality shown to ...

Cardiovascular Toxicity Associated With Bispecific Antibodies in Hematological Malignancies: A Comprehensive Pharmacovigilance Analysis

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Cardiovascular adverse events (CVAEs) associated with bispecific T‐cell engaging antibodies (BsAbs) have not been systematically investigated across approved agents. In this disproportionality analysis of FAERS (December 2014–September 2025), reports listing BsAbs as the primary suspected drug (n = 7647) were compared with all other drugs in ...

B-splines Algorithms for Solving Fredholm Linear Integro-Differential Equations

open access: yesمجلة بغداد للعلوم, 2004
Algorithms using the second order of B -splines [B (x)] and the third order of B -splines [B,3(x)] are derived to solve 1' , 2nd and 3rd linear Fredholm integro-differential equations (F1DEs).

Impact of cumulative glucocorticoid exposure on vancomycin clearance in hospitalized children: A retrospective cohort study

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Prior glucocorticoid exposure is associated with modestly increased vancomycin clearance in hospitalized children, partly mediated by renal function and inflammation and may contribute to subtherapeutic early drug exposure. Abstract Introduction Augmented renal clearance (ARC) can lead to subtherapeutic vancomycin exposure in children.
