Removal of VOC and Heavy Metals through Microbial Approach (2023)

It has been established that volatile organic compounds (VOCs) and heavy metals (HMs) are potential sources of noxiousness and carcinogenic messengers when released into effluents or wastewaters. They can pose serious threats to land, water, and air as well as the health of flora, fauna, and human populations. Several techniques such as adsorption, filtration, and phyto removal, have been used to detoxify, clean, and remove these VOCs and HMs from the environment. These techniques have their inherent limitations such as their non-effectiveness, high cost, and non-eco-friendly nature. To this end, a sustainable and eco-friendly method using biologically based methods for the removal of VOCs and HMs from the environment has been recommended by many environmentalists. In previous years, the application of nanofillers (2D materials, titanium dioxide, Cu, Ag, and Zn nanoparticles, graphene oxides, and nanotubes) have greatly got the attention of many environmental scientists in the areas of HMs, VOCs, microorganism, water treatment, and wastewater management. This chapter intends to discuss detailed methods in the removal of VOCs and HMs from industrial wastes effluent using bio-nano fillers, biosorption, bioscrubber, biotrickling filters, microorganisms, biofilters, and biofiltration. The mechanisms of bio-nano fillers for the removal of HMs and VOCs were discussed. The possible environmental and health impacts of bio-nano fillers in the removal of HMs and VOCs in wastewater were highlighted. The benefits derived from the utilization of bio-nano fillers over other conventional methods were discussed.
Folded shorted patch antenna with an offset feeding probe (2008)

Abstract This article presents the design and performance of a wideband folded shorted patch antenna. The proposed antenna consists of a folded trapezoidal patch that is shorted to the ground plane and is fed by a coaxial probe. By offsetting the probe feeding position from the midline of the patch, wide impedance bandwidth of 56.1% (1.59–2.83 GHz) is obtained for SWR &lt; 2, which is nearly two times that of the antenna without offsetting the probe. The patch of this antenna is 0.071λ 0 in height and 0.35λ 0 in length, where λ 0 is the free space wavelength at the center frequency of its operating bandwidth. Therefore, this antenna is suitable for the multiband indoor wireless communication systems nowadays. © 2008 Wiley Periodicals, Inc.

Machine Learning Prediction of COVID-19 Severity Levels From Salivaomics Data (2022)

The clinical spectrum of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the strain of coronavirus that caused the COVID-19 pandemic, is broad, extending from asymptomatic infection to severe immunopulmonary reactions that, if not categorized properly, may be life-threatening. Researchers rate COVID-19 patients on a scale from 1 to 8 according to the severity level of COVID-19, 1 being healthy and 8 being extremely sick, based on a multitude of factors including number of clinic visits, days since the first sign of symptoms, and more. However, there are two issues with the current state of severity level designation. Firstly, there exists variation among researchers in determining these patient scores, which may lead to improper treatment. Secondly, researchers use a variety of metrics to determine patient severity level, including metrics involving plasma collection that require invasive procedures. This project aims to remedy both issues by introducing a machine learning framework that unifies severity level designations based on noninvasive saliva biomarkers. Our results show that we can successfully use machine learning on salivaomics data to predict the severity level of COVID-19 patients, indicating the presence of viral load using saliva biomarkers.
Identification of high frequency transformer equivalent circuit using Matlab from frequency domain data (2002)

High frequency modelling is essential in the design of power transformers, to study impulse voltage distribution, winding integrity and insulation diagnosis. In this paper, a PC based, fully automated technique for identifying parameters of a high frequency transformer equivalent circuit is proposed. At each discrete measurement point, voltage ratio and phase between input and output is calculated to obtain the frequency response. A parametric system identification technique is utilised to determine the coefficients of an appropriate transfer function to model the measured frequency response from 50 Hz to 1 MHz, divided into low, medium and high frequency ranges. The proposed technique is simple to implement, fully computerised and avoids time consuming measurements reported earlier. Test results on several transformers indicate that the method is highly reliable, consistent and is sensitive to transformer winding faults.
Highly Stable Mixed‐Lanthanide Metal–Organic Frameworks for Self‐Referencing and Colorimetric Luminescent pH Sensing (2016)

Abstract A strategy utilizing mixed‐lanthanide metal–organic frameworks (MOFs) for self‐referencing and colorimetric luminescent pH sensing has been developed. The mixed‐lanthanide MOFs Eu x Tb 1− x Hdpda ( x= 0.097, 0.205, 0.303, H 4 dpda=4‐(3,5‐dicarboxyphenyl)pyridine‐2,6‐dicarboxylic acid) exhibit excellent stability in phosphate buffer solution with pH values varying from 3.90 to 7.50. Density functional theory (DFT) calculations indicate that the deprotonation of uncoordinated carboxyl groups in ligands results in the elevation of the triplet excited state (T 1 ) energy level of H 4 dpda, thus increasing the energy transfer probability from the T 1 to 5 D 4 level of Tb 3+ . As a result, the emission intensity of Tb 3+ in Eu x Tb 1− x Hdpda increases gradually while that of Eu 3+ is almost not changed with the pH varying from 3.90 to 7.50. The intensity ratios of Eu 3+ to Tb 3+ can be correlated to the pH value, suggesting they are promising self‐referencing luminescent pH sensors. Furthermore, the significant pH‐dependent emission color change enables them to act as a luminescent colorimetric pH sensor for in situ and real‐time pH imaging. Because the energy transfer between the ligand and lanthanide ion can be easily tuned by selecting an appropriate ligand to further optimize the pH response range and sensitivity, such a strategy opens a new perspective for the development of self‐referencing luminescent pH sensors.
Design, fabrication and characterization of a hybrid III-V on silicon transmitter for high-speed communications (2016)

Depuis plusieurs années, le volume de données échangé à travers le monde augmente sans cesse. Pour gérer cette large quantité d’information, des débits élevés de transmission de données sur de longues distances sont essentiels. Puisque les interconnections à base de cuivre ne peuvent pas suivre cette tendance, des systèmes de transmission optique rapides sont requis dans les centre de données. Dans ce contexte, la photonique sur silicium est considérée comme une solution pour obtenir des circuits photoniques intégrés à un coût réduit. Bien que cette technologie ait connu une croissance significative au cours de la dernière décennie, les transmetteurs actuels à haut débit de transmission sont principalement basés sur des sources laser externes. Par conséquent, l’objectif de ce travail de thèse était de concevoir et produire un transmetteur à haut débit de transmission de données pour la photonique sur silicium, doté d’une source laser intégrée.Ce transmetteur se compose d’un modulateur silicium de type Mach-Zehnder, co-intégré sur la même plaque avec un laser hybride III-V sur silicium à réseaux de Bragg distribués, dont la longueur d’onde d’émission peut être contrôlée électriquement autour de 1.3μm. La conception des différents éléments constituant à la fois le laser (coupleurs adiabatique entre le III-V et le silicium, miroirs de Bragg) et le modulateur (jonctions p-n, électrodes à ondes progressives) est détaillée, de même que leur fabrication. Pendant la caractérisation des transmetteurs, des taux de transmission de données jusqu’à 25Gb/s, pour des distances allant jusqu’à 10km ont été démontrés avec succès, avec la possibilité de contrôler la longueur d’onde jusqu’à 8.5nm. Par ailleurs, afin d’améliorer l’intégration de la source laser avec le circuit photonique sur silicium, une solution basée sur le dépôt à basse température (en-dessous de 400°C) d’une couche de silicium amorphe pendant la fabrication est aussi évaluée. Des tests sur une cavité laser à contre-réaction distribuée ont montré des performances au niveau de l’état de l’art (avec des puissances de sortie supérieures à 30mW), prouvant ainsi la viabilité de cette approche.

Accurate optical extinction ratio measurements (1994)

We describe a method that increases the accuracy and repeatability of optical extinction ratio measurements from presently several percent to better than one percent. This accuracy is required when optimizing the performance of Gb/s optical transmitters using lasers or modulators for ultra low bit error rates. The method is simple, and can be applied to both research and production measurements.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Right Orbitofrontal Cortex Mediates Conscious Olfactory Perception (2010)

Understanding how the human brain translates sensory impressions into conscious percepts is a key challenge of neuroscience research. Work in this area has overwhelmingly centered on the conscious experience of vision at the exclusion of the other senses--in particular, smell. We hypothesized that the orbitofrontal cortex (OFC) is a central substrate for olfactory conscious experience because of its privileged physiological role in odor processing. Combining functional magnetic resonance imaging, peripheral autonomic recordings, and olfactory psychophysics, we studied a case of complete anosmia (smell loss) in a patient with circumscribed traumatic brain injury to the right OFC. Despite a complete absence of conscious olfaction, the patient exhibited robust "blind smell," as indexed by reliable odor-evoked neural activity in the left OFC and normal autonomic responses to odor hedonics during presentation of stimuli to the left nostril. These data highlight the right OFC's critical role in subserving human olfactory consciousness.
Paediatric patients report lower health‐related quality of life in daily clinical practice compared to new normative PedsQLTM data (2021)

Paediatric patients reported lower HRQOL than the general population, and school absence, female gender and younger age were associated with lower HRQOL. The results underline the importance to structurally monitor paediatric patients' HRQOL in clinical practice to detect problems and offer the right help on time.
Soft gold coatings: influence of additives and pulse plating (2012)

Soft gold for electronics or other applications can be obtained by controlling the structure by metal additions into the electrolyte and also by electrodeposition with very short current pulses and long off times. Soft gold is obtained from baths containing a small quantity of thallium ions as an additive, while hard gold is obtained from similar baths with nickel ions as an alternative additive. Thallium is not deposited, but affects strongly the adsorption phenomena at the gold cathodic surface. By referring to the normality inertia electrokinetic behaviour of the elements in aqueous solutions, it is shown that normal metal ions addition give soft gold deposits, while inert metal addition give hard gold layers. The main influence of normal metal addition is a decrease in the cathodic voltage during deposition, with decrease in inhibition condition coming from complexant interaction with the cathodic surface. A similar effect can be obtained with pulsed current, when the voltage increase is limited, favouring the capacitance charging with respect to the faradaic discharge. In these conditions, lateral growth prevails with respect to outgrowth, which becomes predominant in inhibition conditions. Cyanide and sulphite gold baths show a similar behaviour with respect to inhibition phenomena by complexant at surfaces.
A Celebration of Hayek (1988)

For much of his career, the work of the Austrian economist F. A. Hayek was neglected by all but a small band of academics. The award of the Nobel Prize in Economic Science in 1974 at last brought public recognition to a scholar whose seven decades of work is increasingly seen to offer seminal analysis which will guide the development of economics for at least as long again in the future. Norman Barry, Professor of Politics at the University of Buckingham, examines Hayek's distinguished career.
Molecular Recognition of Muramyl Dipeptide Occurs in the Leucine-rich Repeat Domain of Nod2 (2016)

Genetic mutations in the innate immune receptor nucleotide-binding oligomerization domain-containing 2 (Nod2) have demonstrated increased susceptibility to Crohn's disease, an inflammatory bowel disease that is hypothesized to be accompanied by changes in the gut microbiota. Nod2 responds to the presence of bacteria, specifically a fragment of the bacterial cell wall, muramyl dipeptide (MDP). The proposed site of this interaction is the leucine-rich repeat (LRR) domain. Surface plasmon resonance and molecular modeling were used to investigate the interaction of the LRR domain with MDP. A functional and pure LRR domain was obtained from Escherichia coli expression in high yield. The LRR domain binds to MDP with high affinity, with a K<sub>D</sub> of 212 ± 24 nM. Critical portions of the receptor were determined by mutagenesis of putative binding residues. Fragment analysis of MDP revealed that both the peptide and carbohydrate portion contribute to the binding interaction.
Nanoscopic switching behavior of epitaxial SrBi2Ta2O9 films deposited by pulsed laser deposition (2000)

We report results on scanning force microscopy (SFM) studies of epitaxial SrBi2Ta2O9 films which, in conjunction with complementary x-ray diffraction, scanning and transmission electron microscopy data, allow us to establish direct correlation between the crystallographic structure at the submicrometer range and the nano- and macroscopic switching behavior of the films. SFM topographic analysis of the films revealed a high degree of inhomogeneity at the submicrometer level: a number of rectangular and spherical grains protruding out of the flat surface. It has been found that the ferroelectric behavior of the films is primarily due to the (110) and (100)-oriented grains, while a flat background is c oriented and therefore is not switchable. Remanent polarization values obtained using SFM data were consistent with the results of the macroscopic hysteresis loop measurements.
Tackling the Fermionic Sign Problem in the Auxiliary-Field Monte Carlo Method (2007)

We explore a novel and straightforward solution to the sign problem that has plagued the Auxiliary-field Monte Carlo (AFMC) method applied to many-body systems for more than a decade. We present a solution to the sign problem that has plagued the Auxiliary-field Monte Carlo (AFMC) method for more than a decade and report a breakthrough where excellent agreement between AFMC and exact CI calculations for fully realistic nuclear applications is achieved. This result offers the capability, unmatched by other methods, to achieve exact solutions for large-scale quantum many-body systems.
The Proton-activated Receptor GPR4 Modulates Intestinal Inflammation (2017)

Absence of GPR4 ameliorates colitis in IBD animal models, indicating an important regulatory role in mucosal inflammation, thus providing a new link between tissue pH and the immune system. Therapeutic inhibition of GPR4 may be beneficial for the treatment of IBD.
Si/SiO2 interface studies by spectroscopic immersion ellipsometry and atomic force microscopy (1994)

The dependence of the Si/SiO2 interface characteristics on the thickness and oxidation temperature for SiO2 films grown on different Si orientations was studied by spectroscopic immersion ellipsometry (SIE) and atomic force microscopy (AFM). Essentially, SIE uses liquids that match the refractive index of the films, thereby optically removing the films and consequently increasing the sensitivity to the interface. We show that as the thickness of the thermally grown SiO2 overlayer increases, the thickness of the suboxide layer at the interface also increases, and the average radius of the crystalline silicon protrusions (roughness) at the interface decreases for the three different Si orientations (100), (110), and (111), and two different oxidation temperatures (800 and 1000 °C) studied. The dependence of the interface roughness on the thickness of the SiO2 overlayer was confirmed by AFM. The results include unintentionally and intentionally roughened Si samples and are shown to be consistent with the commonly accepted Si oxidation model.
Impedance, filtering and noise in n-phase passive CMOS mixers (2012)

Here we review a simple Linear Time-Invariant (LTI) model that captures the impedance transparency properties of CMOS passive mixers, as well as filtering and noise effects and compare these analyses to measured results. We then extend this model to account for device parameters and suggest a simple metric for predicting limits to performance as a function of process and frequency. Finally we discuss the requirements such mixers place upon the LO circuits, and interactions between such circuits and performance.
Tactile feedback with adaptive controller for a force-reflecting haptic display. 1. Design (2002)

Describes the development of custom-built tactile feedback hardware and its integration with an available force reflecting haptic interface. Design requirements were motivated strongly by the characteristics of the human tactile sense as well as the biomechanical characteristics of the human finger. The work explores the feasibility of various actuators, and selects a small solenoid actuator for application in a closed-loop force control tactile feedback system. System architecture is described, including a simple PI controller. A companion paper describes an adaptive controller with continuously variable gain scheduling that is based upon this PI controller, and includes an evaluation of the system.

Efficient analysis of polling systems (1992)

A large variety of computer communications systems, in particular the token ring network, are modeled and analyzed as polling systems. The authors present the descendant set approach as a general efficient algorithm for deriving all moments of packet delay (in particular, mean delay) in these systems. The method can apply to a very large variety of model variations including: the exhaustive, gated, and fractional service policies; the cyclic visit order; arbitrary periodic visit orders, (polling tables); random polling orders; and customer routing. For most variations the method significantly outperforms the algorithms commonly used.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Longitudinal control algorithm for automated vehicle merging (2003)

This paper considers longitudinal control of automated vehicle merging in a mathematical approach for automated highway systems. Merging manoeuvre is defined as one vehicle in the merging lane to be inserted in the middle between two vehicles in the main lane at fixed merging point which is the intersection of those two lanes. The main lane vehicles can change speed. To achieve this, the merging vehicle must properly adjust its speed and acceleration such that it reaches the merging point at the right time with the same speed and acceleration as the main lane vehicles. This problem is a little similar to but different from the well-known missile interception problem. The longitudinal control problem is proposed for different road layouts, based on which a unified mathematical model is established. Then a new concept, virtual platooning, is introduced, which effectively avoids a two-point boundary value problem . Based on this concept, an analytic solution with mathematical proof is provided. It is also discretized as a recursive algorithm for real-time use. A dynamic real-time simulation is published at PATH website. This algorithm has been successfully implemented with automated cars.
Effects of thermo-compression bonding parameters on joint formation of micro-bumps in non-conductive film (NCF) (2015)

Effects of thermo-compression bonding parameter on Cu-pillar/Sn-Ag interconnection reliability of NCF-assembled Chip-on-board (COB) package were investigated. Parallelplate modeling of gap size during the thermo-compression bonding process was performed. By using the viscosity/time graph and the modeling, prediction of gap size was performed in both bare chip to chip and real chip to board. The actually NCF bonding of COB module was performed with different heating rate of 5°C/min, 10°C/min, and 20°C/min. The gap height decreased as the heating rate increased and the results well corresponded with the modeling. All the bonded samples showed stable daisy and contact resistance at as bonded state, however 5°C/min sample showed severe T/C failures due to high gap height and unstable wetting of solder on pad.
