Quantization Noise as Superposition of Frequency-Modulated Sinusoids (2009)

A closed-form deterministic description of the quantization noise introduced by an infinite uniform quantizer as a function of an arbitrary input signal is given. The quantization noise can be regarded as a superposition of frequency-modulated (FM) sinusoids. For a band-limited Gaussian noise input signal, the power density spectrum of the quantization noise is derived. For a discrete-time system, conditions for the quantization noise being uniformly distributed and spectrally white are given. The analytic expressions are in excellent agreement with simulation results.

Matrix-assisted laser desorption/ionization time-of-flight analysis ofBacillus spores using a 2.94?�m infrared laser (2000)

The performance of infrared (2.94 microm) and ultraviolet (337 nm) lasers were compared for analysis of purified spores of B. subtilis, B. cereus and B. globigii on a four-inch end-cap reflectron time-of-flight instrument. Infrared matrix-assisted laser desorption/ionization (IR-MALDI) mass spectra of these microorganisms displayed a larger number of biomarker peaks above m/z 4000, compared with UV-MALDI. Biomarker peaks were observed at higher m/z values with the IR laser.
Osteogenic effects of bone‐morphogenetic‐protein‐2 plasmid gene transfer (2007)

The aim of the present study was to test the osteogenic effects of BMP-2 (bone morphogenetic protein-2) gene transfer in BMSCs (bone-marrow stromal cells) and rabbit calvarial bone defects. The pBMP-2-cDNA3.1 plasmid was constructed by subcloning hBMP-2 (human BMP-2) cDNA into the plasmid pcDNA3.1. BMSCs were transfected with a pBMP-2-cDNA3.1-Lipofect-amine complex. Transfected cells were observed for localization of the BMP-2 coding plasmid. Also, the level of BMP-2 in the culture medium of transfected cells was measured. The culture medium was collected and we tested whether this medium could induce non-transfected BMSCs to express ALP (alkaline phosphatase) and osteocalcin. The pBMP-2-cDNA3.1 complexes were incorporated into the collagen scaffold and the plasmid-loaded collagen scaffolds were then grafted into rabbit calvarial defects. After 2 weeks, granulation tissue at the grafted site was obtained and mRNA of BMP-2 was examined via RT (reverse transcriptase)--PCR. After 4 and 8 weeks, the animals were killed and the calvarial tissue was excised. After specimen preparation, optical microscopical examination was performed to evaluate bone formation. The results show that transfected cells were able to incorporate the BMP-2 gene into their nuclei. Also, the level of expressed and secreted BMP-2 was significantly higher in transfected cells than in untransfected cells (P<0.01). The retrieved culture medium could induce the expression of ALP and osteocalcin in non-transfected BMSCs. hBMP-2 mRNA was detected at the granulation tissue of experimental animals, but not in control animals after 2 weeks. At both 4 and 8 weeks, experimental groups showed significantly more newly formed bone area than the control group (P<0.01). Therefore pBMP-2-cDNA3.1 gene delivery could induce BMSCs into osteoblastic phenotype cells and enhance bone regeneration in rabbit calvarial bone defects.
A case of West syndrome with atypical massive gray matter heterotopia that is well controlled by ACTH therapy (1996)

A 4 month old female infant with atypical asymmetrical massive gray matter heterotopia diagnosed as West syndrome is described. Her seizure initially appeared as afebrile general tonic and clonic convulsion and progressed to typical West syndrome consisting of clusters of myoclonic spasms of the extremities, mainly on the left side, accompanied by head and eye deviation to the right side. Electroencephalogram (EEG) presented typical hypsarrhythmia and cranial computerized tomography (CT) and magnetic resonance imaging (MRI) showed massive heterotopic gray matter in the right hemisphere with the same density or intensity as cortical gray matter. Single photon emission computed tomography (SPECT), using N-isopropyl-p-123I-iodoamphetamine (123 I-IMP), demonstrated decreased blood flow in the ectopic lesion. Although clinical response to several anti-epileptic drugs was poor, her seizures were well controlled by relatively low dose adrenocorticotropic hormone (ACTH) therapy of 0.015 mg/kg per day followed by a combination of valproic acid and clonazepam.
12. Les nanoparticules (2013)

Les nanoparticules peuvent être qualifiées de « nouvel état de la matière », c’est-à-dire un état intermédiaire entre les espèces moléculaires en solution et le solide massif. Leurs propriétés remarquables sont à l’origine de l’émergence des nanosciences et de l’essor des nanotechnologies. Si le discours du prix Nobel Richard Feynmann le 29 décembre 1959 fait date, il faudra attendre une trentaine d’années pour qu’une nouvelle ère industrielle impulsée par une course à la miniaturisation, se ...
Building a Fab on a Chip (2014)

Semiconductor fabs are large, complex industrial sites with costs for a single facility approaching $10B. In this paper we discuss the possibility of putting the entire functionality of such a fab onto a single silicon chip. We demonstrate a path forward where, for certain applications, especially at the nanometer scale, one can consider using a single chip approach for building devices with significant potential cost savings. In our approach, we build micro versions of the macro machines one typically finds in a fab, and integrating all the components together. We argue that the technology now exists to allow one to build a Fab on a Chip.
Myomatrix arrays for high-definition muscle recording (2023)

Neurons coordinate their activity to produce an astonishing variety of motor behaviors. Our present understanding of motor control has grown rapidly thanks to new methods for recording and analyzing populations of many individual neurons over time. In contrast, current methods for recording the nervous system's actual motor output - the activation of muscle fibers by motor neurons - typically cannot detect the individual electrical events produced by muscle fibers during natural behaviors and scale poorly across species and muscle groups. Here we present a novel class of electrode devices ('Myomatrix arrays') that record muscle activity at unprecedented resolution across muscles and behaviors. High-density, flexible electrode arrays allow for stable recordings from the muscle fibers activated by a single motor neuron, called a 'motor unit,' during natural behaviors in many species, including mice, rats, primates, songbirds, frogs, and insects. This technology therefore allows the nervous system's motor output to be monitored in unprecedented detail during complex behaviors across species and muscle morphologies. We anticipate that this technology will allow rapid advances in understanding the neural control of behavior and identifying pathologies of the motor system.

Battery efficient design with IEEE P802.21c optimized single radio handovers draft standard (2014)

A multi-radio device may perform dual-radio handovers in a make-before-break manner, at the price of higher peak-power and more sophisticated isolation of receiver signal from radio frequency (RF) interference. The IEEE 802.21c Task Group has developed a media-independent single radio handover specification to avoid these requirements resulting in smaller battery size and less design complexity, and therefore lower cost. This media-independent handover mechanism also enables signaling between different networks.
[The delta F508 mutation which causes cystic fibrosis and its association with closely linked DNA polymorphisms in the Slovak population]. (1992)

Linkage relationships between DNA polymorphism metH/TaqI as well as KM19/PstI and the mutation causing cystic fibrosis (CF) were analyzed in 48 families from Slovakia with th occurrence of CF. The polymorphism metH/TaqI did not show linkage disequilibrium with CF mutation. A pronounced allelic association was however found between CF mutation and KM19/PstI polymorphism. Of the 83 CF chromosomes analyzed, the given mutation was associated with the 6.6 kb allele in 82% of cases, while the rate of this allele in chromosomes without the mutation amounts only to 24%. The value of the standardized disequilibrium coefficient SCD = 0.58. Delta F508 deletion was addressly studied in 25 patients (i.e. 50 CF chromosomes). Of the 50 CF mutations, the given deletion was in 64% (32), while the remaining 36% (18) of mutations were of other, closely not identified types. Delta F508 deletion is in marked allelic association with the 6.6 kb allele of KM19/PstI polymorphism (SCD = 0.68). Between the given allele of KM19/PstI polymorphism and CF mutation no other allelic association was found but with delta F508. (Tab. 6, Fig. 1, Ref. 18).

The Generalization-Stability Tradeoff In Neural Network Pruning (2020)

Pruning neural network parameters is often viewed as a means to compress models, but pruning has also been motivated by the desire to prevent overfitting. This motivation is particularly relevant given the perhaps surprising observation that a wide variety of pruning approaches increase test accuracy despite sometimes massive reductions in parameter counts. To better understand this phenomenon, we analyze the behavior of pruning over the course of training, finding that pruning's benefit to generalization increases with pruning's instability (defined as the drop in test accuracy immediately following pruning). We demonstrate that this generalization-stability tradeoff is present across a wide variety of pruning settings and propose a mechanism for its cause: pruning regularizes similarly to noise injection. Supporting this, we find less pruning stability leads to more model flatness and the benefits of pruning do not depend on permanent parameter removal. These results explain the compatibility of pruning-based generalization improvements and the high generalization recently observed in overparameterized networks.

The results have underlined a good percentage of subjects who don't require further vaccination.
Characterizing Genetic Circuit Components in E. coli towards a Campylobacter jejuni Biosensor (2018)

Abstract Campylobacter jejuni is responsible for most cases of bacterial gastroenteritis (food poisoning) in the United Kingdom. The most common routes of transmission are by contact with raw poultry. Current detection systems for the pathogen are time-consuming, expensive or inaccessible for everyday users. In this article we propose a cheaper and faster system for detection of C. jejuni using a synthetic biology approach. We aimed to detect C. jejuni by the presence of xylulose, an uncommon bacterial capsular saccharide. We characterized two sugar-based regulatory systems that displayed potential to act as tools for detection of xylulose. Using a two-plasmid reporter system in Escherichia coli , we investigated the regulatory protein component (MtlR) of the mannitol operon from Pseudomonas fluorescens . Our findings suggest that the promoter of mtlE is activated by MtlR in the presence of a variety of sugar inducer molecules, and may exhibit cross-activity with a native regulator of E. coli . Additionally, we engineered the L-arabinose transcriptional activator (AraC) of E. coli for altered ligand specificity. We performed site-specific saturation mutagenesis to generate AraC variants with altered effector specificity, with an aim to generate a mutant activated by xylulose. We characterized several mutant AraC variants which have lost the ability to respond specifically to the native L-arabinose effector. We promote this technique as a powerful tool for future iGEM teams to create regulatory circuits activated by novel small molecule ligands.

Characterization of leaves and flowers volatile constituents of Lantana camara growing in central region of Saudi Arabia (2015)

The chemical components of essential oils derived from leaves and flowers of Lantana camara growing in Saudi Arabia are analyzed for the first time using gas chromatography techniques (GC–MS, GC–FID, Co-GC, LRI determination, and database and literature searches) on two different stationary phase columns (polar and nonpolar). This analysis led to the identification of total 163 compounds from leaves and flowers oils. 134 compounds were identified in the oil obtained from leaves of L. camara, whereas 127 compounds were identified in the oil obtained from flowers; these compounds account for 96.3% and 95.3% of the oil composition, respectively. The major components in the oil from leaves were cis-3-hexen-1-ol (11.3%), 1-octen-3-ol (8.7%), spathulenol (8.6%), caryophyllene oxide (7.5%) and 1-hexanol (5.8%). In contrast, the major compounds in the flowers oil were caryophyllene oxide (10.6%), β-caryophyllene (9.7%), spathulenol (8.6%), γ-cadinene (5.6%) and trans-β-farnesene (5.0%). To the best of our knowledge, cis-3-hexen-1-ol and 1-octen-3-ol that were identified as major components in this study have not been reported earlier from Lantana oils.
Broadband design of U-shaped folded dipole antenna for WiMAX by using characteristic mode analysis (2019)

In this study, we utilize an effective method called Characteristic Mode Analysis (CMA) to analyze the physical mechanisms of U-shaped Folded Dipole Antenna (UFDA), which have been proposed for WiMAX device. The proposed antenna consists of the UFDA element and small Ground Plane. As a result, it is confirmed that two types of modes in the resonance of UFDA appear, the one is the mode of the Ground Plane and the other is the mode of the UFDA element. Subsequently, from these results, an easier method for broadband design of UFDA which can cover completely two frequency bands of WiMAX was investigated.
Beat-to-beat P-wave Variability Increases from Paroxysmal to Persistent Atrial Fibrillation (2020)

Atrial fibrillation (AF) is known to worsen over time. Beat-to-beat P-wave variability is used to evaluate the risk of developing AF, but it has not been used to monitor arrhythmia progression in a comprehensive model. The aim of this study is to create a method to measure beat-tobeat P-wave variability to evaluate AF types.
Observation of a coherent backscattering effect with a dipolar source for elastic waves: Highlight of the role played by the source (2001)

We report an experimental evidence of the role played by the source on the coherent backscattering effect (CBE) for elastic waves. The experiment is carried out in a chaotic cavity consisting of a silicon plate whose shape is a quarter stadium. With a monopolar source, it has already been shown that the time-integrated squared amplitude at the point source is twice as large as at the other points around the source. Here, by using a dipolar source, we show that we instead obtain two peaks with the same axis as the dipole one's. The shape of this "bicone" is well explained with a modal theory assuming that the source may be modeled by two sources with opposite phases. Then, the theory is generalized to any multipolar emitter and/or receiver. Particularly, we study CBE when emitter and receiver are reciprocal.

Effects of luminescent coupling in single- and 4-junction dilute nitride solar cells (2014)

A novel method for incorporating the effects of luminescent coupling and photon recycling in numerical simulations of planar devices is described. The carrier generation is incorporated directly in the device simulator as an additional term in the continuity equation, so that no additional iterations are required. The method is applied to single- and four-junction solar cells containing ~1.0 eV dilute nitride material. We find that luminescent coupling increases the short-circuit current (J <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">SC</sub> ) of the 1-junction dilute nitride cell by 2.4% due to coupling with the Al <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.05</sub> Ga <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.95</sub> As filter. In the 4-junction design, there is significant photon recycling within the GaAs and GaInP sub-cells, providing a 60 mV increase in open-circuit voltage. There is a 1.9% relative increase in calculated efficiency to 44.4%.
A modified Redlich‐Kwong equation for supercritical helium and hydrogen (1970)

Abstract A modified Redlich‐Kwong equation of state is developed in which the two parameters are expressed as functions of temperature. The critical values for the two constants in the equation are completely determined by the values of the critical properties of the gas. The optimum values of the constants for each isotherm ( Z vs. P ) are found, followed by a curve‐fitting routine that obtains the constants as functions of temperature. The resulting equation of state predicts experimental helium compressibility data to within an average of 0.90% absolute error for data in the range 0 &lt; pressure ⩽ 700 atm., 5.26°K. ⩽ temperature ⩽ 1,500°K. For hydrogen, the prediction is to within an average of 0.79% absolute error for temperatures from 34° to 600°K. and pressures up to 2,900 atm.
SiGe HBT for application in BiCMOS technology: II. Design, technology and performance (2001)

SiGe technology has acquired great importance in recent years. Recent advances made in the SiGe HBT technology for analogue applications are discussed in this two-part review paper. Strain, stability, reliability, mobility of charge carriers, bandgap narrowing and effective density of states of SiGe layers have been discussed in part I. This paper (part II) is devoted to the HBTs: their design and performance. The two designs of the HBTs developed by IBM and by Daimler-Benz are discussed. Their relative merits and constraints imposed by the stability criterion on each design are described. The technology used for implementing the two designs is also described. The dc and ac characteristics and Ge profiles needed to optimize different figures of merit are discussed in detail. The parasitic barriers created by outdiffusion of B and also on operating the HBT at high current densities are explained. High injection barriers can be suppressed by a special design of the Ge profiles. Introduction of C in the base suppresses outdiffusion of B. HBTs with SiGeC base layers are discussed. Issues involved in simultaneous optimization of fT,fmax and BVCEO are addressed. Values of fT,fmax and BVCEO of high-performance HBTs are compiled and given in a table. The noise characteristics of the SiGe HBTs are far superior to those of III-V devices. Noise in SiGe HBTs is discussed in detail. Finally, a summary of selected circuits that have been fabricated using SiGe HBTs is given.
Topic Models over Spoken Language (2012)

Virtually all work on topic modeling has assumed that the topics are to be learned over a text-based document corpus. However, there exist important applications where topic models must be learned over an audio corpus of spoken language. Unfortunately, speech-to-text programs can have very low accuracy. We therefore propose a novel topic model for spoken language that incorporates a statistical model of speech-to-text software behavior. Crucially, our model exploits the uncertainty numbers returned by the software. Our ideas apply to any domain in which it would be useful to build a topic model over data in which uncertainties are explicitly represented.
Moving‐image‐sticking phenomenon induced by an outside force in liquid‐crystal displays (2008)

Abstract— Image deformation caused by an outside force is observed to remain for hours at high gray levels for liquid‐crystal displays (LCDs) in the multi‐domain (MD) vertical‐alignment (VA) mode. This so‐called moving‐image‐sticking phenomenon demonstrated a non‐symmetric luminance profile for the left and right viewing direction for MDVA‐mode LCDs which have original symmetric viewing‐angle characteristics. The generation of a stable reverse‐tilt domain by an outside force was assumed to be the cause of this phenomenon, and the stability of a reverse‐tilt domain under an electric fringe field was calculated by changing the electric‐fringe‐field distribution which determines the LC tilt direction. The domain of a given tilt direction is calculated to change to other tilt direction induced by a fringe field at a low gray condition, but to remain unchanged at a high gray condition. This agrees with the observed trends of duration time of the moving‐image‐sticking phenomenon.
