PLASMA SECRETIN IN NEONATES (1980)

Plasma secretin has been measured in 96 normal 6-day-old term infants and in 158 healthy preterm infants whose mean post-partum ages were 2 1/2, 6, 13 or 24-days. At birth, plasma secretin levels in both term and preterm infants were high compared with those seen in healthy fasting adults (p less than 0.001), but subsequently declined towards adult values. In contrast, preterm infants who had not been fed for the first 6 days of life, had presistently high basal plasma secretin values. In term infants at 6 days of age and in preterm infants up to 13 days, there was no secretin response to a feed. However, by 24 days, preterm infants showed a marked postprandial secretin elevation (p less than 0.02). No correlations were found between plasma secretin concentrations and either blood glucose or plasma insulin concentrations following a feed. Significant adjustments in plasma secretin levels occur in the early weeks of life which may be influenced by enteral feeding.
Imaging the Aβ-Related Neurotoxicity of Alzheimer Disease (2007)

Our results establish that the neurotoxicity related to the Abeta peptide can be captured in vivo by functional imaging and suggest hippocampal subregions most vulnerable to its toxic effects.
Real-time tracking of moving persons by exploiting spatio-temporal image slices (2000)

This paper addresses the problem of analyzing human motion in an image sequence. This is of particular importance for video-surveillance applications. We have developed an original and efficient approach to track the apparent contours of a moving articulated structure, avoiding the use of 3D models. This method exploits spatio-temporal XT-slices from the image sequence volume XYT, where typical trajectory patterns can be associated with articulated motion such as human walking. We reconstruct these trajectories online by introducing an appropriate predictive model while correctly handling occlusion periods. This paradigm can lead to a simple trajectory recognition scheme. Experiments with real-world images depicting human walk or gesture are reported, and obtained results validate the proposed approach.

How long to wait? (2012)

The bus arrival time is primary information to most city transport travelers. Excessively long waiting time at bus stops often discourages the travelers and makes them reluctant to take buses. In this paper, we present a bus arrival time prediction system based on bus passengers' participatory sensing. With commodity mobile phones, the bus passengers' surrounding environmental context is effectively collected and utilized to estimate the bus traveling routes and predict bus arrival time at various bus stops. The proposed system solely relies on the collaborative effort of the participating users and is independent from the bus operating companies, so it can be easily adopted to support universal bus service systems without requesting support from particular bus operating companies. Instead of referring to GPS enabled location information, we resolve to more generally available and energy efficient sensing resources, including cell tower signals, movement statuses, audio recordings, etc., which bring less burden to the participatory party and encourage their participation. We develop a prototype system with different types of Android based mobile phones and comprehensively experiment over a 7 week period. The evaluation results suggest that the proposed system achieves outstanding prediction accuracy compared with those bus company initiated and GPS supported solutions. At the same time, the proposed solution is more generally available and energy friendly.
Fiber laser mode locked through an evolutionary algorithm (2015)

Mode locking of fiber lasers generally involves adjusting several control parameters, in connection with a wide range of accessible short-pulse dynamics. In this Letter, we experimentally demonstrate the ability of an evolutionary algorithm to prescribe a set of cavity parameters entailing specific self-starting mode locking. The prescribed parameters are applied to electrically driven polarization controllers, thus shaping the effective nonlinear transfer function at play within the fiber cavity. According to the specifications of the objective function used for the optimization procedure, various short-pulse regimes are obtained. Our versatile method represents an effective novel avenue for the exploration and optimization of nonlinear cavity dynamics.
An efficient adaptive predistorter for nonlinear high power amplifier in satellite communication (2002)

This paper presents an efficient adaptive predistortion technique for compensation of linear and nonlinear distortion caused by high-power amplifier with memory in satellite communication channels. The previous adaptive predistortion techniques, based on Volterra series modeling, are not suitable for real-time implementation due to high computational burden and slow convergence rate. In this paper, the memoryless HPA preceded by linear dynamic system is modeled by the Wiener system which is then precompensated by the proposed adaptive predistorter structured by the Hammerstein model. An adaptive algorithm for adjusting the parameters of the predistorter is derived using the stochastic gradient method. The validity of the proposed approach is confirmed via computer simulation by applying it to 16-QAM satellite communication channel where the HPA is preceded by a linear filter.
Replacement of Calcite (CaCO<sub>3</sub>) by Cerussite (PbCO<sub>3</sub>) (2016)

The mobility of toxic elements, such as lead (Pb) can be attenuated by adsorption, incorporation, and precipitation on carbonate minerals in subsurface environments. Here, we report a study of the bulk transformation of single-crystal calcite (CaCO<sub>3</sub>) into polycrystalline cerussite (PbCO<sub>3</sub>) through reaction with acidic Pb-bearing solutions. This reaction began with the growth of a cerussite shell on top of calcite surfaces followed by the replacement of the remaining calcite core. The external shape of the original calcite was preserved by a balance between calcite dissolution and cerussite growth controlled by adjusting the Pb<sup>2+</sup> concentration and pH. The relation between the rounded calcite core and the surrounding lath-shaped cerussite aggregates was imaged by transmission X-ray microscopy, which revealed preferentially elongated cerussite crystals parallel to the surface and edge directions of calcite. The replacement reaction involved concurrent development of ∼100 nm wide pores parallel to calcite c-glide or (12̅0) planes, which may have provided permeability for chemical exchange during the reaction. X-ray reflectivity measurements showed no clear epitaxial relation of cerussite to the calcite (104) surface. These results demonstrate Pb sequestration through mineral replacement reactions and the critical role of nanoporosity (3% by volume) on the solid phase transformation through a dissolution-recrystallization mechanism.
Metric Conversion (1976)

Passage of the Metric Conversion Act of 1975 marked the latest of the United States' efforts to replace our customary system of measurement with a metric system, in this case the International System of Units (SI). It is almost certain that the change will take place, since it is supported by a significant number of government agencies, of industries and their trade associations, and of scientific and engineering societies. The effect of conversion on the units of measurement used by the SMPTE in its future publications and standards is discussed, and present practices are touched upon.
Measuring Adherence To Asthma Medication Regimens (1994)

The failure of patients to adhere to physician-prescribed regimens, either pharmacologic or behavioral, has been well documented in medical literature. Poor adherence to asthma medication regimens has been repeatedly demonstrated in both children and adults, with rates of nonadherence commonly reported from 30 to 70%. Medication regimens for asthma care are particularly vulnerable to adherence problems because of their duration, the use of multiple medications, and the periods of symptom remission. The clinical effects of this nonadherence by asthmatic patients can include treatment failure, unnecessary and dangerous intensification of therapy, and costly diagnostic procedures, complications, and hospitalizations. Although the measurement of adherence is an important component of both medical and behavioral interventions to control asthma, relatively little research has directly addressed the reliability and validity of the measures most widely used to assess asthma medication compliance. This review will discuss methods and issues in the measurement of adherence in general, and where available, measures that have been specifically used in evaluating adherence to asthma medication. Common measures used to assess compliance with asthma medications include direct measures, which confirm the use of medication by assaying it in blood, urine, or saliva, or which confirm the to use a medication, such as observed skill in using a metered dose inhaler. Indirect measures infer use with varying degrees of reliability, by use of clinical judgment, self-report/asthma diaries, medication measurement, and electronic medication monitors. The uses and limitations of these measures will be discussed.

Distinct Roles of Jasmonates and Aldehydes in Plant-Defense Responses (2008)

The data suggest that jasmonates and hexenyl acetate play distinct roles in mediating direct and indirect plant-defense responses. The potential advantage of this "division of labor" is to ensure the most effective defense strategy that minimizes incurred damages at a reduced metabolic cost.
Robot Soccer System of SOTY 5 for Middle League MiroSot (2002)

Developing a multi-agent system amounts to searching for a method to implement an intelligent system composed of multiple cooperative agents with independent motion control. Multi-agent systems are more flexible and fault tolerant as several simple robot agents are easier to handle and cheaper to build compared to a single powerful robot for di#erent tasks. Middle League MiroSot is a suitable testbed for multi-agent system research. The soccer game is di#erent from other multiagent systems, in that the robots in one team have to cooperate in the face of competition from the opponent team. The multi-agent control algorithm must comprise of low level kinematics and dynamics, and high level strategies to avoid obstacles and to compete with the opponent robots. In such a dynamic environment, a robot needs fast processing algorithms and a suitable robot structure. This paper presents the development of an SOTY 5 team robot for the Middle League MiroSot game. The e#ectiveness of the new robot soccer team will be demonstrated at the 2002 FIRA Cup.

Data Leakage Detection (2010)

We study the following problem: A data distributor has given sensitive data to a set of supposedly trusted agents (third parties). Some of the data are leaked and found in an unauthorized place (e.g., on the web or somebody's laptop). The distributor must assess the likelihood that the leaked data came from one or more agents, as opposed to having been independently gathered by other means. We propose data allocation strategies (across the agents) that improve the probability of identifying leakages. These methods do not rely on alterations of the released data (e.g., watermarks). In some cases, we can also inject “realistic but fake” data records to further improve our chances of detecting leakage and identifying the guilty party.
A Novel Hyperbolic Smoothing Algorithm for Clustering Large Data Sets (2009)

The minimum sum-of-squares clustering problem is considered. The mathematical modeling of this problem leads to a min i sum i min formulation which, in addition to its intrinsic bi-level nature, has the signiflcant characteristic of being strongly nondifierentiable. To overcome these di‐culties, the proposed resolution method, called Hyperbolic Smoothing, adopts a smoothing strategy using a special C 1 difierentiable class function. The flnal solution is obtained by solving a sequence of low dimension difierentiable unconstrained optimization This paper presents an extended method based upon the partition of the set of observations in two non overlapping parts. This last approach engenders a drastic simpliflcation of the computational tasks.
Sortase A Utilizes an Ancillary Protein Anchor for Efficient Cell Wall Anchoring of Pili in <i>Streptococcus agalactiae</i> (2008)

Pili are putative virulence factors and promising vaccine candidates in Streptococcus agalactiae (group B Streptococcus [GBS]) infection, a leading cause of neonatal sepsis and meningitis. The genes necessary for pilus synthesis and assembly are clustered in pilus islands (PI). Each gene encodes three structural subunits (a backbone and two ancillary proteins) bearing a C-terminal LPXTG motif and two subfamily C sortases (SrtC) involved in covalent polymerization of the subunits. GBS strains also possess the conserved "housekeeping" sortase A (SrtA), but its role in pilus assembly is unclear. To address this issue, pilus expression and cell wall anchoring were analyzed in srtA deletion mutants. Loss of SrtA did not affect pilus polymerization. However, pilus expression on the cell surface was reduced, and pili accumulated in the culture supernatant. Furthermore, cell-associated pili could be readily released by detergent treatment, indicating that SrtA is involved in covalent anchoring of pili to the cell wall. When each of the genes comprising PI-2a was systematically deleted, only the absence of ancillary subunit GBS150 or the SrtC required for incorporation of GBS150 into pili mimicked the srtA mutant phenotype. Thus, from these data a model for GBS pilus assembly can be proposed in which PI sortases are responsible for polymerization of the pilus structure, while SrtA is required to covalently attach it to the cell wall, utilizing ancillary pilus subunit GBS150 as the anchor protein.
A PEG Construction of Finite-Length LDPC Codes with Low Error Floor (2012)

The progressive-edge-growth (PEG) algorithm of Hu et al. is modified to improve the error floor performance of the constructed low-density parity-check (LDPC) codes. To improve the error floor, the original PEG algorithm is equipped with an efficient algorithm to find the dominant elementary trapping sets (ETS's) that are added to the Tanner graph of the under-construction code by the addition of each variable node and its adjacent edges. The aim is to select the edges, among the candidates available at each step of the original PEG algorithm, that prevent the creation of dominant ETS's. The proposed method is applicable to both regular and irregular variable node degree distributions. Simulation results are presented to demonstrate the superior ETS distribution and error floor performance of the constructed codes compared to similar codes constructed by the original and other modifications of the PEG algorithm.
Empirical earnings functions for Iran (2001)

Some recent studies have debated the appropriateness of semi-log earnings function in approximating actual earnings profiles. This study contributes further to this debate by estimating four specifications of earnings function, namely, semi-log quadratic, semi-log cubic, quadratic and cubic with cross section data for 4035 full-time urban male earners in Iran for 1993. The analysis shows that the semi-log quadratic earnings function fits the actual empirical earnings profiles very poorly. The quadratic earnings function provides a much better approximation to the actual earnings. Measures of out-of-sample prediction errors also show the superiority of quadratic function over others.
Constructing an interactive natural language interface for relational databases (2014)

Natural language has been the holy grail of query interface designers, but has generally been considered too hard to work with, except in limited specific circumstances. In this paper, we describe the architecture of an interactive natural language query interface for relational databases. Through a carefully limited interaction with the user, we are able to correctly interpret complex natural language queries, in a generic manner across a range of domains. By these means, a logically complex English language sentence is correctly translated into a SQL query, which may include aggregation, nesting, and various types of joins, among other things, and can be evaluated against an RDBMS. We have constructed a system, NaLIR (Natural Language Interface for Relational databases), embodying these ideas. Our experimental assessment, through user studies, demonstrates that NaLIR is good enough to be usable in practice: even naive users are able to specify quite complex ad-hoc queries.
Prediction of survival using absolute lymphocyte count for newly diagnosed patients with multiple myeloma: a retrospective study (2008)

Absolute lymphocyte count (ALC) recovery after autologous stem cell transplantation for multiple myeloma (MM) has been reported to be an independent prognostic factor for clinical outcome. The role of ALC on survival in newly diagnosed untreated MM patients is unknown. Between 1994 and 2002, we analysed retrospectively 537 MM patients of 1835 consecutive MM patients that were neither uniformly treated nor part of a clinical trail, but originally diagnosed and followed at the Mayo Clinic. The primary endpoint was to assess the role of ALC at the time of MM diagnosis on overall survival (OS). The median follow-up was 35.1 months (range: 1-152.5 months). ALC, as a continuous variable, was identified as prognostic factor for OS (Hazard ratio = 0.473, 95% confidence interval = 0.359-0.618, P < 0.0001). MM patients with an ALC >/=1.4 x 10(9)/l experienced superior OS compared with MM patients with an ALC <1.4 x 10(9)/l (65 vs. 26 months, P < 0.0001). Multivariate analysis identified ALC as an independent prognostic factor for OS. This study showed that, in newly diagnosed MM, ALC is an independent prognostic factor for OS, suggesting a significant role of host immune status in the survival of MM.
The Use of Partial Residual Plots in Regression Analysis (1972)

This paper defines partial residuals in multiple linear regression. The ith partial residual vector can be thought of as the dependent variable vector corrected for all independent variables except the ith variable. A plot of the ith partial residuals vs values of the ith variable is proposed as a replacement for the usual plot displaying ordinary residuals vs the ith independent variable. This partial residual plot shows the extent and direction of linearity, while displaying deviations from linearity, such as outliers, inhomogeneity of variance, and curvilinear relationships. Some alternative definitions of partial residuals are described.
Identification of a small molecule that simultaneously suppresses virulence and antibiotic resistance of Pseudomonas aeruginosa (2016)

The rising antibiotic resistance of bacteria imposes a severe threat on human health. Inhibition of bacterial virulence is an alternative approach to develop new antimicrobials. Molecules targeting antibiotic resistant enzymes have been used in combination with cognate antibiotics. It might be ideal that a molecule can simultaneously suppress virulence factors and antibiotic resistance. Here we combined genetic and computer-aided inhibitor screening to search for such molecules against the bacterial pathogen Pseudomonas aeruginosa. To identify target proteins that control both virulence and antibiotic resistance, we screened for mutants with defective cytotoxicity and biofilm formation from 93 transposon insertion mutants previously reported with increased antibiotic susceptibility. A pyrD mutant displayed defects in cytotoxicity, biofilm formation, quorum sensing and virulence in an acute mouse pneumonia model. Next, we employed a computer-aided screening to identify potential inhibitors of the PyrD protein, a dihydroorotate dehydrogenase (DHODase) involved in pyrimidine biosynthesis. One of the predicted inhibitors was able to suppress the enzymatic activity of PyrD as well as bacterial cytotoxicity, biofilm formation and antibiotic resistance. A single administration of the compound reduced the bacterial colonization in the acute mouse pneumonia model. Therefore, we have developed a strategy to identify novel treatment targets and antimicrobial molecules.
