A Worldwide Survey on the Use of Social Networking in Higher Education
Social networking is becoming a more powerful tool for students for communication, information sharing, and discussions. This paper presents a study, based on a survey questionnaire, which aims to investigate to what extent and...
Oriented Type I Collagen - A Review on Artificial Alignment Strategies
Collagen is the most abundant protein in the human body and serves many functions, from mechanical stability and elasticity in tendons and bone, to optical properties, such as transparency and a fine tuned refractive index in...
Cross-Cultural Effects in Adoption Patterns of a Mobile Coaching Service for Studies
This study applied an adoption model, inspired by the Technology Acceptance Model (TAM) and Multipurpose Information Appliances Adoption Model (MIAAM), to compare key variables explaining adoption patterns of a mobile coaching...
Analysis of Psychomotricity in Digital Didactic Materials in Early Childhood
This article is part of the research project titled “Digital Teaching Materials in Early Childhood Education: Analysis and Proposals for Use at School and at Home (INFANCI@ DIGIT@L).” The fundamental objective was to analyse the...
Factors Influencing the Behavioural Intention to Use AI-Generated Images in Business
Motivated by the need to better understand the ongoing role of artificial intelligence in businesses and to shift the focus from a purely technological and algorithmic perspective to one that encompasses human-computer...
Fast nonnegative least squares through flexible Krylov subspaces
Silvia Gazzola, Yves Wiaux
Apr 27, 2017
Constrained least squares problems arise in a variety of applications, and many iterative methods are already available to compute their solutions. This paper proposes a new efficient approach to solve nonnegative linear least...

Regularization by inexact Krylov methods with applications to blind deblurring
This paper is concerned with the regularization of large-scale discrete inverse problems by means of inexact Krylov methods. Specifically, we derive two new inexact Krylov methods that can be efficiently applied to unregularized...

Flexible Krylov Methods for <i>L</i><sub>p</sub> regularization
In this paper we develop flexible Krylov methods for efficiently computing regularized solutions to large-scale linear inverse problems with an `2 fit-to-data term and an `p penalization term, for p ≥ 1. First we approximate the...

The structure of Wntch signalling and the resolution of transition states in development
During development, the emergence of different cell fates and their patterning into tissues and organs requires spatio-temporal coordination that controls the relative number of different cell types. Genetic analyses in...

Dysregulation of haematopoietic stem cell regulatory programs in acute myeloid leukaemia.
Haematopoietic stem cells (HSC) are situated at the apex of the haematopoietic differentiation hierarchy, ensuring the life-long supply of mature haematopoietic cells and forming a reservoir to replenish the haematopoietic...

Some transpose-free CG-like solvers for nonsymmetric ill-posed problems
This paper introduces and analyzes an original class of Krylov subspace methods that provide an efficient alternative to many well-known conjugate-gradient-like (CG-like) Krylov solvers for square nonsymmetric linear systems...
