A New Full-Newton Step $O(n)$ Infeasible Interior-Point Algorithm for $P_*(\kappa)$-horizontal Linear Complementarity Problems [PDF]

Computer Science Journal of Moldova, 2014
In this paper, we first present a brief review about the feasible interior-point algorithm for $P_*(\kappa)$-horizontal linear complementarity problems (HLCPs) based on new directions.

A global pricing extension of the simplex method [PDF]

Operations Research and Decisions
We introduce the use of a global, nonlinear price function in linear programming and the simplex method. The usual, linear price function of this method captures the objective's behaviour over the cone of directions defined by the nonbasic columns ...

Direct ultrasonic holography: Feasibility demo [PDF]

Acoustics Research Letters Online, 2005
Holography is potentially the most powerful method for high spatial resolution real time 3D ultrasound imaging and diagnostics. Although versions of ultrasound holography have existed since the 1970s, they use laser reconstruction, thus losing 3-D resolution.

The NFDA-Nonsmooth Feasible Directions Algorithm applied to construction of Pareto Fronts of Ridge and Lasso Regressions

Trends in Computational and Applied Mathematics
Ridge and Lasso regressions are types of linear regression, a machine learning tool for dealing with data. Based on multiobjective optimization theory, we transform Ridge and Lasso regression into bi-objective optimization problems. The Pareto fronts of

A family of global convergent inexact secant methods for nonconvex constrained optimization

Journal of Algorithms & Computational Technology, 2018
We present a family of new inexact secant methods in association with Armijo line search technique for solving nonconvex constrained optimization. Different from the existing inexact secant methods, the algorithms proposed in this paper need not compute ...

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Feasibility of Smartphone-Based Badminton Footwork Performance Assessment System

Sensors, 2020
Footwork is the most fundamental skill in badminton, involving the ability of acceleration or deceleration and changing directions on the court, which is related to accurate shots and better game performance. The footwork performance in-field is commonly
