Tunable Optical De-aggregation of a 40-Gbit/s 16-QAM Signal into Two 20-Gbit/s 4-PAM Signals using a Coherent Frequency Comb and Nonlinear Processing (2016)

We experimentally de-aggregate the 16-QAM signal (EVM 6.9%) onto two 4-PAM signals (EVM 8.5%). Tunability of the approach over modulation format and bit rate is also shown by de-aggregating QPSK signals at two different baud rates.
Angular momentum transport by heat-driven g-modes in slowly pulsating B stars (2017)

Motivated by recent interest in the phenomenon of waves transport in massive stars, we examine whether the heat-driven gravity (g) modes excited in slowly-pulsating B (SPB) stars can significantly modify the stars' internal rotation. We develop a formalism for the differential torque exerted by g modes, and implement this formalism using the GYRE oscillation code and the MESASTAR stellar evolution code. Focusing first on a $4.21$ $M_\odot$ model, we simulate 1,000 years of stellar evolution under the combined effects of the torque due to a single unstable prograde g mode (with an amplitude chosen on the basis of observational constraints), and diffusive angular momentum transport due to convection, overshooting, and rotational instabilities. We find that the g mode rapidly extracts angular momentum from the surface layers, depositing it deeper in the stellar interior. The angular momentum transport is so efficient that by the end of the simulation the initially non-rotating surface layers are spun in the retrograde direction to $\approx30\%$ of the critical rate. However, the additional inclusion of magnetic stresses in our simulations, almost completely inhibits this spin-up. Expanding our simulations to cover the whole instability strip, we show that the same general behavior is seen in all SPB stars. After providing some caveats to contextualize our results, we hypothesize that the observed slower surface rotation of SPB stars (as compared to other B-type stars) may be the direct consequence of the angular momentum transport that our simulations demonstrate.
The effect of reduced alcohol consumption on blood pressure: a randomised, controlled, single blind study. (1987)

A randomised, controlled, single blind trial was conducted in office workers with mild hypertension (systolic blood pressure (SBP) 140 to 180 mmHg, diastolic blood pressure (DBP) 90 to 110 mmHg) to determine the effect of decreasing alcohol consumption. After a baseline examination, 50 male volunteers aged 30 to 59 were randomised to two groups. Group A were told to abstain from or reduce alcohol consumption for two weeks, while group B were instructed to maintain their usual alcohol consumption. Complete records were obtained on 49 subjects. The daily alcohol consumption of groups A and B at baseline was similar, i.e. 71.9 ml and 72.5 ml of ethanol, respectively, and changed to 16.1 ml and 62.9 ml, respectively, during the experiment. After two weeks, group A were asked to resume their normal consumption whilst group B were asked to reduce or abstain (phase II). However in view of a treatment period interaction, statistical analysis was confined to phase I. During phase I, group A, whose alcohol consumption had reduced, showed decreases of 5.8 and 7.1 mmHg in SBP during the the first and second weeks, respectively. In group B, these decreases were only 0.6 and 1.9 mmHg, respectively. The difference between the falls in SBP in groups A and B was significant (P = 0.005) as judged by analysis of variance. The DBP also decreased, but there was no significant difference between the decreases in the two groups. Changes in gamma-glutamyl-transpeptidase, a biochemical marker of alcohol consumption, from the initial values to the end of phase I were significantly different in groups A and B.(ABSTRACT TRUNCATED AT 250 WORDS)

Nanoparticle formation in a low pressure argon/aniline RF plasma (2018)

The formation of nanoparticles in low temperature plasmas is of high importance for different fields: from astrophysics to microelectronics. The plasma based synthesis of nanoparticles is a complex multi-scale process that involves a great variety of different species and comprises timescales ranging from milliseconds to several minutes. This contribution focuses on the synthesis of nanoparticles in a low temperature, low pressure capacitively coupled plasma containing mixtures of argon and aniline. Aniline is commonly used for the production of polyaniline, a material that belongs to the family of conductive polymers, which has attracted increasing interest in the last few years due to the large number of potential applications. The nanoparticles which are formed in the plasma volume and levitate there due to the collection of negative charges are investigated in this contribution by means of in-situ FTIR spectroscopy. In addition, the plasma is analyzed by means of plasma (ion) mass spectroscopy. The experiments reveal the possibility to synthesize nanoparticles both in continuous wave and in pulsed discharges. The formation of particles in the plasma volume can be suppressed by pulsing the plasma in a specific frequency range. The in-situ FTIR analysis also reveals the influence of the argon plasma on the characteristics of the nanoparticles.
Trajectory Clustering and an Application to Airspace Monitoring (2011)

This paper presents a framework aimed at monitoring the behavior of aircraft in a given airspace. Trajectories that constitute typical operations are determined and learned using data-driven methods. Standard procedures are used by air traffic controllers (ATCs) to guide aircraft, ensure the safety of the airspace, and maximize runway occupancy. Even though standard procedures are used by ATCs, control of the aircraft remains with the pilots, leading to large variability in the flight patterns observed. Two methods for identifying typical operations and their variability from recorded radar tracks are presented. This knowledge base is then used to monitor the conformance of current operations against operations previously identified as typical. A tool called AirTrajectoryMiner is presented, aiming at monitoring the instantaneous health of the airspace, in real time. The airspace is “healthy” when all aircraft are flying according to typical operations. A measure of complexity is introduced, measuring the conformance of current flight to typical flight patterns. When an aircraft does not conform, the complexity increases as more attention from ATC is required to ensure safe separation between aircraft.
Speedup and performance improvement of ICA-based robot audition by parallel and resampling-based block-wise processing (2010)

This paper describes a speedup and performance improvement of multi-channel semi-blind ICA (MCSB-ICA) with parallel and resampling-based block-wise processing. MCSB-ICA is an integrated method of sound source separation that accomplishes blind source separation, blind dereverberation, and echo cancellation. This method enables robots to separate user's speech signals from observed signals including the robot's own speech, other speech and their reverberations without a priori information. The main problem when MCSB-ICA is applied to robot audition is its high computational cost. We tackle this by multi-threading programming, and the two main issues are 1) the design of parallel processing and 2) incremental implementation. These are solved by a) multiple-stack-based parallel implementation, and b) resampling-based overlaps and block-wise separation. The experimental results proved that our method reduced the real-time factor to less than 0.5 with an eight-core CPU, and it improves the performance of automatic speech recognition by 2-10 points compared with the single-stack-based parallel implementation without the resampling technique.
American Society of Transplantation Symposium on B Cells in Transplantation: Harnessing Humoral Immunity from Rodent Models to Clinical Practice (2007)

There is growing awareness that B cells and alloantibodies are important mediators of both acute and chronic allograft injury. Unfortunately, few therapies are clinically available to mitigate the function of B cells or the effects of established alloantibody. As a result, many sensitized people await transplantation without a suitable donor, and several rejection syndromes are emerging that appear to involve B cells either as antibody producers or as antigen-presenting cells. In recognition of this unmet need in transplantation, the American Society of Transplantation organized a Symposium on B cells in Organ Transplantation to foster interest in this topic amongst basic researchers attending the annual meeting of the American Association of Immunologists. This manuscript will give an overview of the presentations from this symposium including the current risks of allosensitization, adaptive accommodation, approaches toward B-cell tolerance for allo- and xenoantigens and clinical application of these concepts in ABO incompatible neonatal cardiac transplantation.
Tag-to-reader harmonic link in passive UHF RFID (2014)

This paper presents a new communication concept for the passive UHF RFID technology, by means of the exploitation of harmonics signals generated by passive UHF RFID chips. The presence of information carried on the harmonics is experimentally shown by conducted measurements on three different EPC Class-1 Gen2 RFID chips. Therefore, and in compliance with the standard requirements, these results are used in the optimal design of a new tag that increases the power level of the harmonic response, while operating also at the fundamental frequency. The performance of this solution is illustrated from simulation and measurement. Results show an improvement of 11 dB on the 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> harmonic response compared to commercial tags, thereby, enabling new applications, concepts and functionalities for the RFID technology. To the knowledge of the authors, no similar study has been presented in the literature.
Learning with the Weighted Trace-norm under Arbitrary Sampling Distributions (2011)

We provide rigorous guarantees on learning with the weighted trace-norm under arbitrary sampling distributions. We show that the standard weighted trace-norm might fail when the sampling distribution is not a product distribution (i.e. when row and column indexes are not selected independently), present a corrected variant for which we establish strong learning guarantees, and demonstrate that it works better in practice. We provide guarantees when weighting by either the true or empirical sampling distribution, and suggest that even if the true distribution is known (or is uniform), weighting by the empirical distribution may be beneficial. 1
Cavity-locked ring down spectroscopy (2023)

Distinct locking and sampling light beams are used in a cavity ring-down spectroscopy (CRDS) system to perform multiple ring-down measurements while the laser and ring-down cavity are continuously locked. The sampling and locking light beams have different frequencies, to ensure that the sampling and locking light are decoupled within the cavity. Preferably, the ring-down cavity is ring-shaped, the sampling light is s-polarized, and the locking light is p-polarized. Transmitted sampling light is used for ring-down measurements, while reflected locking light is used for locking in a Pound-Drever scheme.
Erratum to: Measurement of hadronic event shapes in high-pT multijet final states at $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector (2021)

An error in the normalization of the Aplanarity and D-parameter has been found. Insufficient precision on the eigenvalue calculation can cause 3 to be negative, exclusively in two-jet events, yielding an underestimation of the inclusive two-jet cross section.
Afterword (2008)

Once upon a time, some four and one-half billion or so years ago, the Earth was a dreadful, horrid place from what we can tell based upon various geological records. Cosmic debris from the formation of the solar system rained down nearly continuously on the Earth causing the oceans to boil, evaporate, and reform. Volcanoes spewed forth foul gases. The atmosphere was a noxious mix of nitrogen, ammonia, water vapor, methane, hydrogen sulfide, hydrogen cyanide, and carbon dioxide, with few traces of oxygen. In such a world nothing could live and nothing did. Then, something happened. Within a half billion years after the cosmic barrage had diminished, life sprang forth on Earth - simple, one-celled life, but certainly life. For science, the question has always been, "How did life arise from nonlife?" This puzzle, which is central to our existence, remains to this day an unsolved great mystery. The stage

A Thermal Model of a Forced-Cooled Heat Sink for Transient Temperature Calculations Employing a Circuit Simulator (2006)

Power semiconductors can be modeled as a thermal network of resistors and capacitors. The thermal boundary condition of such a model is typically defined as the heat sink surface temperature, which is assumed to be constant. In reality, the heat sink surface temperature underneath the power module is not exactly known. In this paper we show how to set up a thermal model of the heat sink in form of a RC thermal equivalent network that can be directly embedded in any circuit simulator. The proposed thermal heat sink model takes into account convection cooling, thermal hotspots on the heat sink base plate, thermal time constants of the heat sink, and thermal coupling between different power modules mounted onto the heat sink. Experimental results are given and show high accuracy of the heat sink model with temperature errors below 10%.
Overview of Whole-Genome Essentiality Analysis (2008)

Genomic sequencing has transformed modern biology into an age of global analysis of gene expression, protein pathways, and metabolic networks. To understand wholecell function, biologists and bioinformaticians in many fields have developed a diverse set of methods and tools to identify genes essential to a particular organism under a particular set of conditions. Gene Essentiality: Protocols and Bioinformatics reviews many of these diverse techniques and experimental procedures developed to analyze entire genomes of a variety of prokaryotes and eukaryotes.

Field emission-related electronic properties of single diamond nanodots are studied using tight-binding calculations and continuum electrostatic simulations.
A Cost-Effective, Fast, and Robust Annotation Tool (2017)

Deep learning requires huge datasets for training their models. In most cases, dataset generation is done manually or by using conventional approaches which are time consuming, costly, and prone to inaccuracy. There is an urgent need for developing fast, robust, and effective techniques to annotate each image with different labels and classes based on its contents. In this paper, we propose the use of in-house annotation tool that can be used for generating accurate datasets in a short time with minimal human interference. The proposed tool reads a captured video and the operator manually highlights the objects with their assigned classes in the initial frame. A robust and fast object tracking approach was developed to detect and track each highlighted object for subsequent frames. Experimental results using our annotation tool show 50x to 200x faster processing time compared to conventional annotation methods in addition to better performance with higher accuracy.
Improved fabrication of micro air-channels by incorporation of a structural barrier (2004)

The fabrication of air-channels for microelectromechanical systems and microfluidic devices using polynorbornene and polycarbonates as thermally or photolitically decomposable materials to form air-gaps in dielectric materials has been reported. In this study, the incompatibility of some overcoat polymers with the sacrificial materials was addressed. SiO2 was used as a barrier layer for the fabrication of single- and multi-layer air-channels via different sacrificial and overcoat materials. The structural rigidity of SiO2 mitigates problems associated with overcoat polymers that can easily deform at the processing temperature (overcoat cure or sacrificial decomposition temperature). The chemical inertness and low permeability of SiO2 allows the use of solvent-cast polymers, for which the solvents would have otherwise dissolved the sacrificial material.

Acquiring Creative Requirements from the Crowd: Understanding the Influences of Personality and Creative Potential in Crowd RE (2016)

As a creative discipline, Requirements Engineering (RE), lends importance to understanding the associated human factors. Crowd RE, the approach of acquiring requirements from members of the public-the so-called crowd-emphasizes human factors further. We investigate how human personality and creative potential influence a requirement acquisition task. These factors are of specific importance to Crowd RE because (1) crowd workers are generally not trained in RE, and (2) a key motivation in engaging them is to benefit from their creativity. We propose a sequential Crowd RE process, where workers in one stage review requirements from the previous stage and produce additional requirements. To reduce potential information overload in this process, we propose strategies for selecting requirements from one stage to expose to workers in later stages. We conducted a study on Amazon Mechanical Turk tasking 300 workers with creating requirements via the above sequential process (in the domain of smart home applications for concreteness) and tasking an additional 300 workers to rate the creativity (novelty and usefulness) of those requirements. Our findings offer insights on how to carry out Crowd RE effectively. First, we find that a crowd worker's (1) creative potential, and personality traits of openness and conscientiousness have significant positive influence on the novelty of the worker's ideas, and (2) personality traits of agreeableness and conscientiousness have significant positive influence, but extraversion has significant negative influence on the usefulness of the worker's ideas. Second, we find that exposing a worker to ideas from previous workers cognitively stimulates the worker to produce creative ideas. Third, we identify effective strategies based on personality traits and creative potential for selecting a few requirements from a pool of previous requirements to stimulate a worker.
Effects of Structural Deformations on Optical Properties of Tetrabenzoporphyrins: Free-Bases and Pd Complexes (2008)

A recently developed method of synthesis of pi-extended porphyrins made it possible to prepare a series of tetrabenzoporphyrins (TBP) with different numbers of meso-aryl substituents. The photophysical parameters of free-bases and Pd complexes of meso-unsubstituted TBP's, 5,15-diaryl-TBP's (Ar2TBP's) and 5,10,15,20-tetraaryl-TBP's (Ar4TBP's) were measured. For comparison, similarly meso-arylsubstituted porphyrins fused with nonaromatic cyclohexeno-rings, i.e. Ar(n)-tetracyclohexenoporphyrins (Ar(n)TCHP's, n = 0, 2, 4), were also synthesized and studied. Structural information was obtained by ab initio (DFT) calculations and X-ray crystallography. It was found that: 1) Free-base Ar4TBP's are strongly distorted out-of-plane (saddled), possess broadened, red-shifted spectra, short excited-state lifetimes and low fluorescence quantum yields (tau(fl) = 2-3 ns, phi(fl) = 0.02-0.03). These features are characteristic of other nonplanar free-base porphyrins, including Ar4TCHP's. 2) Ar2TBP free-bases possess completely planar geometries, although with significant in-plane deformations. These deformations have practically no effect on the singlet excited-state properties of Ar2TBP's as compared to planar meso-unsubstituted TBP's. Both types of porphyrins retain strong fluorescence (tau(fl) = 10-12 ns, phi(fl) = 0.3-0.4), and their radiative rate constants (k(r)) are 3-4 times higher than those of planar H2TCHP's. 3) Nonplanar deformations dramatically enhance nonradiative decay of triplet states of regular Pd porphyrins. For example, planar PdTCHP phosphoresces with high quantum yield (phi(phos) = 0.45, tau(phos) = 1118 micros), while saddled PdPh4TCHP is practically nonemissive. In contrast, both ruffled and saddled PdAr(n)TBP's retain strong phosphorescence at ambient temperatures (PdPh2TBP: tau(phos) = 496 micros, phi(phos) = 0.15; PdPh4TBP: tau(phos) = 258 micros, phi(phos) = 0.08). It appears that pi-extension is capable of counterbalancing deleterious effects of nonplanar deformations on triplet emissivity of Pd porphyrins.
