Development of an ImmunoFET for Analysis of Tumour Necrosis Factor- (alfa) in Artificial Saliva: Application for Heart Failure Monitoring
Assessing tumour necrosis factor-(alfa) (TNF-(alfa)) levels in the human body has become an essential tool to recognize heart failure (HF). In this work, label-free, rapid, easy to use ImmunoFET based on an ion-sensitive ...
First observation of the decays ¯¯¯B0(s)→D+sK−π+π− and ¯¯¯B0s→Ds1(2536)+π−
The first observation of the decays ¯¯¯ B 0 s → D + s K − π + π − and ¯¯¯ B 0 → D + s K − π + π − are reported using an integrated luminosity of 1.0 fb − 1 recorded by the LHCb experiment. The branching fractions, ...
Determination of the Sign of the Decay Width Difference in the B0s System
The interference between the K + K − S -wave and P -wave amplitudes in B 0 s → J / ψ K + K − decays with the K + K − pairs in the region around the ϕ ( 1020 ) resonance is used to determine the variation of the difference ...
A Feedfordward Adaptive Controller to Reduce the Imaging Time of Large-Sized Biological Samples with a SPM-Based Multiprobe Station
The time required to image large samples is an important limiting factor in SPM-based systems. In multiprobe setups, especially when working with biological samples, this drawback can make impossible to conduct certain ...
The proangiogenic potential of a novel calcium releasing biomaterial: Impact on cell recruitment
In current bone tissue engineering approaches the achievement of sufficient angiogenesis, during tissue regeneration, is a major limitation in order to attain full tissue functionality. Recently, our group has found that ...
Drift compensation of gas sensor array data by Orthogonal Signal Correction
Drift is an important issue that impairs the reliability of gas sensing systems. Sensor aging, memory effects and environmental disturbances produce shifts in sensor responses that make initial statistical models for gas ...
ICAM-1 Targeting of Nanocarriers in a Human Blood-Brain-Barrier-on-a-Chip Complements In Vivo Brain Delivery Observations
Targeting therapeutic nanocarriers (NCs) to endothelial receptors favours transport across the blood-brain barrier (BBB), a main obstacle to access the brain. While these strategies compel validation in animals, quantitative ...
Application of a floating well concept to a latch-up-free, low-cost, smart power high-side switch technology
The aim of this brief is to present an original design methodology that permits implementing latch-up-free smart power circuits on a very simple, cost-effective technology. The basic concept used for this purpose is letting ...
Synthesis and thermoelectric properties of noble metal ternary chalcogenide systems of Ag-Au-Se in the forms of alloyed nanoparticles and colloidal nanoheterostructures
The optimization of a material functionality requires both the rational design and precise engineering of its structural and chemical parameters. In this work, we show how colloidal chemistry is an excellent synthetic ...
A gated single-photon avalanche diode array fabricated in a conventional CMOS process for triggered systems
A bidimensional array based on single-photon avalanche diodes for triggered imaging systems is presented. The diodes are operated in the gated mode of acquisition to reduce the probability to detect noise counts interfering ...
Vacancy and interstitial depth profiles in ion-implanted silicon
An experimental method of studying shifts between concentration-versus-depth profiles of vacancy- and interstitial-type defects in ion-implanted silicon is demonstrated. The concept is based on deep level transient ...
Improvement of the quality factor of RF integrated inductors by layout optimization
A systematic method to improve the quality (Q) factor of RF integrated inductors is presented in this paper. The proposed method is based on the layout optimization to minimize the series resistance of the inductor coil, ...
Portable Bio-Devices: Design of Electrochemical Instruments from Miniaturized to Implantable Devices
The integration of biosensors and electronic technologies allows the development of biomedical systems able to diagnose and monitoring pathologies by detecting specific biomarkers. The chapter presents the main modules ...
A physical frequency-dependent compact model for RF integrated inductors
A frequency-dependent compact model for inductors in high ohmic substrates, which is based on an energy point-of-view, is developed. This approach enables the description of the most important coupling phenomena that take ...
Trackability of distal access catheters: an in vitro quantitative evaluation of navigation strategies
Background: In mechanical thrombectomy (MT), distal access catheters (DACs) are tracked through the vascular anatomy to reach the occlusion site. The inability of DACs to reach the occlusion site has been reported as a ...
Design and fabrication of a microsystem to handle biological objects
Biological particle microhandling is a common operation in medicine and microbiology, and a lot of research work has been addressed to develop faster, cheaper and more efficient manipulation techniques. In this way, ...
Dynamic compact thermal models with multiple power sources: application to an ultrathin chip stacking technology
Whereas numerical modeling using finite-element methods (FEM) can provide transient temperature distribution in the component with enough accuracy, it is of the most importance the development of compact dynamic thermal ...
Microfluidic 3D platform to evaluate endothelial progenitor cell recruitment by bioactive materials
Most of the conventional in vitro models to test biomaterial-driven vascularization are too simplistic to recapitulate the complex interactions taking place in the actual cell microenvironment, which results in a poor ...
Epitaxial growth of biferroic YMnO3(0001) on platinum electrodes
Epitaxial films of the biferroic YMnO3 (YMO) oxide have been grown on platinum-coated SrTiO3(1 1 1) and Al2O3(0 0 0 1) substrates. The platinum electrodes, (1 1 1) oriented, are templates for the epitaxy of the hexagonal ...
Understanding odor information segregation in the olfactory bulb by means of mitral and tufted cells
Odor identification is one of the main tasks of the olfactory system. It is performed almost independently from the concentration of the odor providing a robust recognition. This capacity to ignore concentration information ...
