Near Infrared Reflectance Spectroscopy for Analysis of Sugarcane from Clonal Evaluation Trials: I. Fibrated Cane (1991)

Determination of quality components is important in assessing the economic merit of clones in sugarcane ( Saccharum spp. hybrids) evaluation trials. Laboratory throughput is limiting and analytical costs are high. This research aimed to assess near infrared reflectance (NIR) spectroscopy for analyzing fibrated cane to resolve these problems. A replicated trial provided samples of cane. Quality components were analyzed by routine laboratory methods. Samples of fibrated cane were scanned, using a Technicon 450R NIR spectrophotometer to provide reflectance data (log I/R). Sampling analyses indicated all routine lab determinations were performed with high accuracy relative to plot‐to‐plot variation and subsampling was annecessary. Correlation coefficients ( r ) obtained for the prediction test for fibrated cane were: Brix (0.91), commercial cane sugar (0.91), conductivity (0.20), fiber (0.89), moisture (0.92), polarimetry reading (0.96), and parity (0.60). Regressions for moisture and pol reading were significantly skewed. The NIR and routine lab analyses did not differ significantly for any component. Precision of NIR analysis compared with routine lab analysis was inferior for all components except purity. Error ratios ranged from 1.3to 3.4. Sampling analyses of spectrophotometer readings (as log 1/ R ) revealed inadequate sample fibration, mixing, and presentation as potential major sources of error. Analysis of fibrated cane is promising, but insufficiently accurate for advanced selection stages. The substantial operational advantages of fibrated cane analysis warrant further research to resolve the problems described.
Utilizing elevator for wireless sensor data collection in high-rise structure monitoring (2011)

Recently wireless sensor networks have been widely suggested for Structural Health Monitoring. In such applications, diverse sensor nodes are deployed in a building structure, collecting ambient data such as temperature and strain from various locations and reporting them to a central base station for processing and diagnosing. For today's high-rise structures (e.g., the Guangzhou New TV Tower, a project that we have participated in, peaks at 600m above ground), the extensive vertical dimension creates enormous challenges toward sensor data collection, beyond those addressed in state-of-the-art motelike systems. For example, with a straightforward base station placement, a huge amount of data will accumulate as being relayed to the base station. As such, the sensor nodes close to the base station would quickly run out of energy for relaying the traffic. The accumulated traffic would also saturate the wireless medium, introducing significant interferences and collisions. The extensive height of these building structures, however, make elevators an indispensable component. This motivates us to develop EleSense, a novel high-rise structure monitoring framework that explores using elevators. In EleSense, an elevator is attached with the base station and collects data when it moves across different floors to serve passengers, which can effectively reduce the traffic accumulation and the collection delay. To maximally exploit the benefit, we take a unique angle with the cross-layer design. We present an abstraction of the high-rise structure monitoring problem that exploits elevators, and model it as a joint optimization across link scheduling, packet routing and end-to-end delivery. We propose a centralized algorithm to solve it optimally. We further propose a distributed implementation to accommodate the hardware capability of a sensor node and address other practical issues. We evaluate EleSense through ns-2 simulations and with real configurations from the Guangzhou New TV Tower. The results show that EleSense has a throughput gain of 30.4% to 200.6% over the case without elevators. We also observe a gain of 40.5% to 127.5% over a straightforward 802.11 MAC scheme without the cross-layer optimization. Moreover, EleSense can significantly reduce the communication costs while maintaining excellent fairness with reliable data delivering.
El pueblo islandés vota en contra de los banqueros: un laboratorio del neoliberalismo devastado por la crisis (2011)

En Estados Unidos, los republicanos luchan por amputar el presupuesto federal; en Portugal, las autoridades negocian soberania por plan de rescate; en Grecia, la perspectiva de una reestructuracion de la deuda endurece la austeridad. Bajo la presion de los especuladores, los Gobiernos han optado por la impotencia. Los islandeses, consultados en un referendum, sugieren una via distinta: que paguen la crisis aquellos que la han provocado.
Cloning, Expression, and Chaperone-like Activity of Human αA-Crystallin (1996)

One of the major protein components of the ocular lens, alpha-crystallin, is composed of alphaA and alphaB chain subunits that have structural homology to the family of mammalian small heat shock proteins. Like other small heat shock proteins, alpha-crystallin subunits associate to form large oligomeric aggregates that express chaperone-like activity, as defined by the ability to suppress nonspecific aggregation of proteins destabilized by treatment with a variety of denaturants including heat, UV irradiation, and chemical modification. It has been proposed that age-related loss of sequences at the C terminus of the alphaA chain subunit may be a factor in the pathogenesis of cataract due to diminished capacity of the truncated crystallin to protect against nonspecific aggregation of lens proteins. To evaluate the functional consequences of alpha-crystallin modification, two mutant forms of alphaA subunits were prepared by site-directed mutagenesis. Like wild type (WT), aggregates of approximately 540 kDa were formed from a tryptophan-free alphaA mutant (W9F). When added in stoichiometric amounts, both WT and W9F subunits completely suppressed the heat-induced aggregation of aldose reductase. In contrast, subunits encoded by a truncation mutant in which the C-terminal 17 residues were deleted (R157STOP), despite having spectroscopic properties similar to WT, formed much larger aggregates with a marked reduction in chaperone-like activity. Similar results were observed when the chaperone-like activity was assessed through inhibition of gamma-crystallin aggregation induced by singlet oxygen. These results demonstrate that the structurally conservative substitution of Phe for Trp-9 has a negligible effect on the functional interaction of alphaA subunits, and that deletion of C-terminal sequences from the alphaA subunit results in substantial loss of chaperone-like activity, despite overall preservation of secondary structure.
Mathematical modeling and parameter estimation of blood pressure oscillometric waveform (2012)

In this paper, a mathematical model for the blood pressure oscillometric waveform (OMW) is developed and a statespace approach using the extended Kalman filter (EKF) is proposed to adaptively estimate and track parameters of clinical interest. The OMW model is driven by a previously proposed pressure-lumen area model of the artery under the deflating cuff. The arterial lumen area is a function of vessel properties, the cuff pressure, and the arterial pressure. Over the deflation period, the arterial pressure causes lumen area oscillations while the deflating cuff pressure adds a slow-varying component to these oscillations. In the previous literature, it has been demonstrated that the oscillometric pulses are proportional to the arterial area oscillations. In this paper, the OMW is modeled as the difference between the whole lumen area model and the slow-varying component of the lumen area caused by the deflating cuff pressure. The OMW model is then represented in the statespace and the extended Kalman filter (EKF) is incorporated to estimate and track the time-varying model parameters during the cuff deflation period. The parameter tracking performance of the EKF is evaluated on a simulated noisy OMW.

Suppression of Transient Overvoltages on Instrumentation Wiring Systems (1985)

Modern electronic analog instrumentation equipment is vulnerable to damage by transient overvoltages appearing on signal and power supply wiring. Experience with overvoltages and relatively simple techniques to avoid damage are discussed.
Workload and Resource Aware Proactive Auto-scaler for PaaS Cloud (2016)

Elasticity is a key feature in Cloud Computing where virtualized resources are provisioned and de-provisioned via auto-scaling. However, auto-scaling in most Platform-as-a-Service (PaaS) systems is based on reactive, threshold-driven approaches. Such systems are incapable of catering to rapidly varying workloads, unless the associated thresholds are sufficiently low. Alternatively, maintaining low thresholds leads to resource over-provisioning under relatively stable workloads. Moreover, thresholds are not a good indication of QoS compliance, which is a key performance indicator of a cloud application. Hence, it is nontrivial to determine an optimum threshold while minimizing costs and meeting QoS demands. We propose inteliScaler, a proactive and cost-aware auto-scaling solution to address these issues by combining a predictive model, cost model, and a smart killing feature. An ensemble workload prediction mechanism is introduced based on time series and machine learning techniques for making accurate predictions on drastically different workload patterns. Utility of the solution is demonstrated using both simulations and empirical evaluations using Apache Stratos PaaS (deployed on the AWS EC2), as well as RUBiS and real-world workload traces. Results show significant QoS improvements and cost reductions by inteliScaler compared to a typical reactive and threshold-based PaaS auto-scaling solution.
A comprehensive system for facial animation of generic 3D head models driven by speech (2013)

A comprehensive system for facial animation of generic 3D head models driven by speech is presented in this article. In the training stage, audio-visual information is extracted from audio-visual training data, and then used to compute the parameters of a single joint audio-visual hidden Markov model (AV-HMM). In contrast to most of the methods in the literature, the proposed approach does not require segmentation/classification processing stages of the audio-visual data, avoiding the error propagation related to these procedures. The trained AV-HMM provides a compact representation of the audio-visual data, without the need of phoneme (word) segmentation, which makes it adaptable to different languages. Visual features are estimated from the speech signal based on the inversion of the AV-HMM. The estimated visual speech features are used to animate a simple face model. The animation of a more complex head model is then obtained by automatically mapping the deformation of the simple model to it, using a small number of control points for the interpolation. The proposed algorithm allows the animation of 3D head models of arbitrary complexity through a simple setup procedure. The resulting animation is evaluated in terms of intelligibility of visual speech through perceptual tests, showing a promising performance. The computational complexity of the proposed system is analyzed, showing the feasibility of its real-time implementation.
Extended-$\hbox{p}^{+}$ Stepped Gate LDMOS for Improved Performance (2010)

In this brief, we propose a new extended-p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> stepped gate (ESG) thin-film silicon-on-insulator laterally double-diffused metal-oxide-semiconductor (LDMOS) with an extended-p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> region beneath the source and a stepped gate structure in the drift region of the LDMOS. The hole current generated due to impact ionization is now collected from an n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> - p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> junction instead of an n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> -p junction, thus delaying the parasitic bipolar junction transistor action. The stepped gate structure enhances RESURF in the drift region and minimizes the gate-drain capacitance. Based on 2-D simulation results, we show that the ESG LDMOS exhibits approximately 63% improvement in breakdown voltage, 38% improvement in on-resistance, 11% improvement in peak transconductance, 18% improvement in switching speed, and 63% reduction in gate-drain charge density compared with the conventional LDMOS with a field plate.
Lactococcus garvieae: Where Is It From? A First Approach to Explore the Evolutionary History of This Emerging Pathogen (2013)

The population structure and diversity of Lactococcus garvieae, an emerging pathogen of increasing clinical significance, was determined at both gene and genome level. Selected lactococcal isolates of various origins were analyzed by a multi locus sequence typing (MLST). This gene-based analysis was compared to genomic characteristics, estimated through the complete genome sequences available in database. The MLST identified two branches containing the majority of the strains and two branches bearing one strain each. One strain was particularly differentiated from the other L. garvieae strains, showing a significant genetic distance. The genomic characteristics, correlated to the MLST-based phylogeny, indicated that this "separated strain" appeared first and could be considered the evolutionary intermediate between Lactococcus lactis and L. garvieae main clusters. A preliminary genome analysis of L. garvieae indicated a pan-genome constituted of about 4100 genes, which included 1341 core genes and 2760 genes belonging to the dispensable genome. A total of 1491 Clusters of Orthologous Genes (COGs) were found to be specific to the 11 L. garvieae genomes, with the genome of the "separated strain" showing the highest presence of unique genes.
ibeA, a virulence factor of avian pathogenic Escherichia coli (2005)

The presence of ibeA, a gene encoding a known virulence factor of Escherichia coli strains responsible for neonatal meningitis in humans, was investigated in the genome of 213 avian pathogenic E. coli (APEC) strains and 55 non-pathogenic E. coli strains of avian origin. Fifty-three strains were found to be ibeA(+), all of which belonged to the APEC group. The ibeA gene is therefore positively linked to the pathogenicity of strains (P<0.0001). Analysis of the serogroup of strains revealed a positive association of ibeA with serogroups O18, O88 and O2. On the contrary, only 1/59 O78 strains are ibeA(+), indicating a negative association of ibeA with this serogroup (P<0.0001). The role of ibeA in the virulence of the APEC strain BEN 2908 was investigated by constructing an ibeA mutant. Challenge assays on 3-week-old chickens showed a reduced virulence for the ibeA mutant. Furthermore, the APEC strain BEN 2908 was able to invade brain microvascular epithelial cells, this invasion being significantly reduced upon inactivation of ibeA. Altogether, these results suggest a role of ibeA in the pathogenicity of some APEC strains and confirm the close relationship between APEC and other human extraintestinal pathogenic E. coli isolates.
Gene activation in response to neural induction. (1993)

In order to study the molecular processes involved in the final steps of neural induction, we are investigating the transcriptional regulation of the Xenopus laevis neural cell adhesion molecule (NCAM) gene. NCAM is expressed very early during neural development and its expression is dependent on neural induction signals. Using microinjection of reporter gene constructions into fertilized frog eggs, we have shown that cloned copies of the NCAM promoter respond appropriately to neural induction signals. Examination of the Xenopus NCAM promoter reveals a number of potential regulatory elements. We have directed our attention to a small region of the promoter that is highly conserved over large evolutionary distances. This region contains an enhancer, the OZ element, and also a silencer element, the N-box. We have purified DNA DNA proteins that interact specifically with both the OZ enhancer and the N-box silencer sequences. A model suggesting a role for these regulatory factors during neural induction is presented.

Optical, electrical and electromechanical measurement methodologies of field, charge and polarization in dielectrics (1998)

A selective review is presented of the use of optical, electrical, and electromechanical measurement methodologies of the electric field, charge, conductivity, and permittivity in dielectrics. Kerr electro-optic measurements are presented to demonstrate how volume charge distributions can distort the electric field distribution significantly and how the field and charge distributions depend on dielectric and electrode materials and geometry, and on voltage magnitude, polarity, and time duration. A new class of interdigital dielectrometry sensors is reviewed which from one side can measure profiles in dielectric permittivity and conductivity and related physical properties such as moisture content. Electromechanical devices such as the absolute charge sensor, a flow loop, and the couette charger (cc) with a rotating cylindrical electrode are reviewed for their applications in liquid flow electrification measurements.

Some new ways of defining the entropy of a process by observing a single typical output sequence as well as a new kind of Shannon-McMillan-Breiman theorem are presented. This provides a new and conceptually very simple ways of estimating the entropy of an ergodic stationary source as well as new insight into the workings of such well-known data compression schemes as the Lempel-Ziv algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Listeria monocytogenes and Brochothrix thermosphacta were investigated by the 16S rRNA cataloguing approach in order to determine their phylogenetic relationship. Both species are specifically, although moderately related, forming one of several sublines within the Bacillus-Lactobacillus-Streptococcus cluster of the ‘Clostridium’ subbranch of Gram-positive eubacteria.
In vitro virulence marker: growth of dengue-2 virus in human leukocyte suspension cultures (1981)

We wished to find a simple, biologically relevant method to evaluate the virulence of dengue viruses for human beings. Since cells of mononuclear phagocyte lineage may be important sites of dengue infection in primates, we evaluated the permissiveness of these cells to dengue virus as a correlate of virus virulence. Two wild-type, large-plaque, monkey-virulent dengue-2 virus strains and two small-plaque, monkey-avirulent dengue-2 virus strains were evaluated for their ability to replicate in human peripheral blood leukocyte cultures supplemented with enhancing antibody. One of the small-plaque strains was demonstrated to have reduced virulence for man. Wild-type dengue-2 viruses replicated readily in peripheral blood leukocyte suspension cultures, whereas small-plaque dengue-2 strains did not. Differences between our data and results obtained by other workers employing adherent peripheral blood leukocytes are discussed. Antibody-enhanced growth of dengue virus in suspension cultures of human peripheral blood leukocytes gives promise of being a simple in vitro system for characterizing dengue virus virulence.
Large First Hyperpolarizabilities in Push-Pull Polyenes by Tuning of the Bond Length Alternation and Aromaticity (1994)

Conjugated organic compounds with 3-phenyl-5-isoxazolone or N,N'-diethylthiobarbituric acid acceptors have large first molecular hyperpolarizabilities (beta) in comparison with compounds with 4-nitrophenyl acceptors. For example, julolidinyl-(CH=CH)(3)-CH=N,N'- diethylthiobarbituric acid, which has 12 atoms between the donor and acceptor, has a beta(0) of 911 x 10(-30) electrostatic units, whereas (CH(3))(2)NC(6)H(4),-(CH=CH)(4)-C(6)H(4)NO(2), with 16 atoms between its donor and acceptor, has a beta(0) of 133 x 10(-30) electrostatic units. The design strategies demonstrated here have resulted in chromophores that when incorporated into poled-polymer electrooptic modulators exhibited significant enhancements in electrooptic coefficients relative to polymers containing the commonly used dye Disperse Red-1. Poled polymer devices based on these or related chromophores may ultimately lead to high-speed electrooptic switching elements with low drive-power requirements, suitable for telecommunications applications.
Genetic Ablation of TASK-1 (Tandem of P Domains in a Weak Inward Rectifying K <sup>+</sup> Channel–Related Acid-Sensitive K <sup>+</sup> Channel-1) (K <sub>2P</sub> 3.1) K <sup>+</sup> Channels Suppresses Atrial Fibrillation and Prevents Electrical Remodeling (2019)

AF was associated with increased TASK-1 transcript, protein and ion current levels leading to shortened action potential duration in atrial cardiomyocytes compared to sinus rhythm controls, similar to previous findings in humans. Anti-TASK-1 adeno-associated viral application significantly reduced AF burden in comparison to untreated AF pigs. Antiarrhythmic effects of anti-TASK-1-siRNA were associated with reduction of TASK-1 currents and prolongation of action potential durations in atrial cardiomyocytes to sinus rhythm values. Conclusions Adeno-associated viral-based anti-TASK-1 gene therapy suppressed AF and corrected cellular electrophysiological remodeling in a porcine model of AF. Suppression of AF through selective reduction of TASK-1 currents represents a new option for antiarrhythmic therapy.
Neurospora mating type symbol mt revised to mat (1997)
