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...
Fine-scale computations for adaptive processing in the human brain
Adapting to the environment statistics by reducing brain responses to repetitive sensory information is key for efficient information processing. Yet, the fine-scale computations that support this adaptive processing in the...
Arnoldi decomposition, GMRES, and preconditioning for linear discrete ill-posed problems
GMRES is one of the most popular iterative methods for the solution of large linear systems of equations that arise from the discretization of linear well-posed problems, such as boundary value problems for elliptic partial...

Immunocapture of <i>Escherichia coli</i> in a fluoropolymer microcapillary array
Isabel P. Alves, Nuno Reis
Jan 25, 2019
This study presents novel experimental insights into the direct quantitation and immunocapture of bacteria cells in a fluoropolymer microcapillary array, using Escherichia coli as work model, a pathogen responsible for around...
Microfluidic smartphone quantitation of <i>Escherichia coli</i> in synthetic urine
Isabel P Alves, Nuno M Reis
Dec 01, 2019

In spite of the clinical need, there is a major gap in rapid diagnostics for identification and quantitation of E. coli and other pathogens, also regarded as the biggest bottleneck in the fight against the spread of...

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...
A high-throughput multi-microfluidic crystal generator (MMicroCryGen) platform for facile screening of polymorphism and crystal morphology for pharmaceutical compounds

In this work, a novel multi-microfluidic crystallization platform called MMicroCryGen is presented, offering a facile methodology for generating individual crystals for fast and easy screening of the polymorphism and crystal...

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...

Antibody Surface Coverage Drives Matrix Interference in Microfluidic Capillary Immunoassays

The performance of biosensors is often optimized in buffers, which brings inconsistencies during applications with biological samples. Current strategies for minimizing sample (matrix) interference are complex to automate and...

Analysis of an iteration method for the algebraic Riccati equation
We consider a recently published method for solving algebraic Riccati equations. We present a new perspective on this method in terms of the underlying linear-quadratic optimal control problem: we prove that the matrix obtained...
The ADI method for bounded real and positive real Lur'e equations
We propose an algorithm for the numerical solution of the Lur'e equations in the bounded real and positive real lemma for stable systems. The algorithm provides approximate solutions in low-rank factored form. We prove that the...

High order splitting methods for SDEs satisfying a commutativity condition

In this paper, we introduce a new simple approach to developing and establishing the convergence of splitting methods for a large class of stochastic differential equations (SDEs), including additive, diagonal, and scalar...

Transparent, Hydrophobic Fluorinated Ethylene Propylene Offers Rapid, Robust, and Irreversible Passive Adsorption of Diagnostic Antibodies for Sensitive Optical Biosensing

Current literature data is scarce and somehow contradictory in respect to the suitability of "nonstick" fluoropolymer surfaces for immobilization of biomolecules. We have previously shown empirically that transparent Teflon...

A lower bound for the balanced truncation error for MIMO systems
Mark Opmeer, Timo Reis
Jul 24, 2015
We show that for a class of systems which includes state space symmetric systems, the balanced truncation error is bounded from below by twice the sum of the tail of the Hankel singular values (including multiplicities) divided...
