Suprasegmental Measures of Accentedness and Judgments of Language Learner Proficiency in Oral English (2010)

In high‐stakes oral proficiency testing as well as in everyday encounters, accent is the most salient aspect of nonnative speech. Prior studies of English language learners’ (ELLs’) pronunciation have focused on single parameters of English, such as vowel duration, fundamental frequency as related to intonation, or temporal measures of speech production. The present study addresses a constellation of suprasegmental characteristics of nonnative speakers of accented English, combining indices of speech rate, pause, and intonation. It examines relations between those acoustic measures of accentedness and listeners’ impressions of second‐language oral proficiency. Twenty‐six speech samples elicited from iBT TOEFL ® examinees were analyzed using a KayPENTAX Computerized Speech Laboratory. Monolingual U.S. undergraduates ( n = 188) judged the speakers’ oral proficiency and comprehensibility. A multiple regression analysis revealed the individual and joint predictiveness of each of the suprasegmental measures. The innovative aspect of this study lies in the fact that the multiple features of accentedness were measured via instrumentation rather than being rated by judges who may, themselves, be subject to rating biases. The suprasegmental measures collectively accounted for 50% of the variance in oral proficiency and comprehensibility ratings, even without taking into consideration other aspects of oral performance or of rater predilections.
LibriMix: An Open-Source Dataset for Generalizable Speech Separation (2020)

In recent years, wsj0-2mix has become the reference dataset for single-channel speech separation. Most deep learning-based speech separation models today are benchmarked on it. However, recent studies have shown important performance drops when models trained on wsj0-2mix are evaluated on other, similar datasets. To address this generalization issue, we created LibriMix, an open-source alternative to wsj0-2mix, and to its noisy extension, WHAM!. Based on LibriSpeech, LibriMix consists of two- or three-speaker mixtures combined with ambient noise samples from WHAM!. Using Conv-TasNet, we achieve competitive performance on all LibriMix versions. In order to fairly evaluate across datasets, we introduce a third test set based on VCTK for speech and WHAM! for noise. Our experiments show that the generalization error is smaller for models trained with LibriMix than with WHAM!, in both clean and noisy conditions. Aiming towards evaluation in more realistic, conversation-like scenarios, we also release a sparsely overlapping version of LibriMix's test set.

Goodness of Prediction Fit for Multivariate Linear Models (1996)

Abstract Using both frequentist and Bayesian techniques, predicting densities are derived for future observations from a multivariate linear model with matrix normal error terms. All the candidates belong to a general location-scale family of predicting densities. An analytic comparison is undertaken, using a Kullback—Leibler loss, by citing an optimal member of a subclass including most of these predicting densities as members. The subclass is based on an invariant Student-t random matrix, and the optimal member is the Bayesian predictive density corresponding to a Jeffreys noninformative prior. Information-based numerical comparisons illustrate the nature of the dominance.
Interplay between coagulation and vascular inflammation in sickle cell disease (2013)

Sickle cell disease is the most common inherited haematological disorder that leads to the irreversible damage of multiple organs. Although sickling of red blood cells and vaso-occlusion are central to the pathophysiology of sickle cell disease, the importance of haemolytic anaemia and vasculopathy has been recently recognized. A hypercoagulable state is another prominent feature of sickle cell disease and is mediated by activation of both intrinsic and extrinsic coagulation pathways. Growing evidence demonstrates that coagulation may not only contribute to the thrombotic complications, but also to vascular inflammation associated with this disease. This article summarizes the role of vascular inflammation and coagulation activation, discusses potential mechanisms responsible for activation of coagulation and reviews recent data demonstrating the crosstalk between coagulation and vascular inflammation in sickle cell disease.
Novel single-stage isolated power-factor-corrected power supplies with regenerative clamping (2002)

Single-stage isolated power-factor-corrected power supplies (SSIPP) have the attractive feature of fast regulation and single control loop. In this paper we further propose to add a very simple regenerative clamping circuit to SSIPP to reduce the voltage stress and to recycle the energy trapped in the leakage inductance of the isolation transformer, thus eliminating the need for a lossy snubber circuit. In addition, this proposed clamping circuit also provides a mechanism to reset the magnetizing current of the output transformer of SSIPP employing a forward converter as the output stage. Simulations and experimental results are reported to verify the operation and performance of the SSIPP with regenerative clamping.
Design of Terachertz Transmission Devices in 2-D Photonic Crystal (2009)

Transmission characteristics of 2-D photonic crystals in terachertz band are studied by using the plane-wave expansion method(PWM).A new terachertz transmission device,namely square Column composed square crystal lattice photonic crystal,is designed.The largest cylinder composed of square crystal lattice photonic TE-mode,TM-mode and complete band gap is calculated and compared.It is discovered that the TE-mode formed by square Column composed square crystal lattice photonic crystal is bigger.The results indicate that the square Column composed square crystal lattice is suitable for manufacturing H polarized piece and terachertz transmission devices.
Antihypertensive and metabolic effects of a combination of hydrochlorothiazide and amiloride. (1981)

A combination of hydrochlorothiazide 50 mg and amiloride 5 mg (HTZ + AMl) was administered twice daily for 12 weeks to 18 hypertensive patients, as a monotherapy. There was a statistically and clinically significant decrease in the mean blood pressure level throughout the treatment period. Significant steady or random changes in blood variables included decreases in chloride, magnesium and bilirubin levels and increases in sodium, calcium, phosphorus, creatinine, triglycerides, total protein, albumin, alkaline phosphatase and SGPT levels, Blood urea nitrogen values changed biphasically. Most of these statistically significant metabolic changes had no clinical relevance. The dosage problem with HTZ + AMl is discussed.
A symbolic-neural classification system assisting the characterization of the Lyme-disease (2003)

The work presented is intended as a step toward hybrid systems and describes a closed-loop integration of a connectionist network into a symbolic concept-learning system. The system is aimed at exploiting many of the powerful features of neural nets to enhance the inherent capabilities of symbolic inductive learning. Backpropagated multilayer perceptrons have been employed to adaptively control how the symbolic system consults declarative knowledge. Conversely, the training of neural networks is under the full control of symbolic tasks. The test case is related to a still open medical diagnosis problem. The main features of the hybrid system are discussed in the light of the preliminary results obtained.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

The peroxidase activity,specific activity and isozyme were analysed in twenty chestnut(Castanea henryi)varieties with different resistance The results showed that after inoculation,the peroxidase activity and specific activity of the resistant varieties were all higher than the susceptible ones at 72 hours,the activity and specific activity of all the varieties reached the highest point at 120 hours The peroxidase isozyme before inoculation didn't indicate the difference of the resistance and susceptibilities among the varieties There appeared 2 new peroxidase isozyme bands in the resistant varieties,1～2 in the middle resistant ones and 0～1 in the susceptible ones after inoculation
Characterization of the putative chloride channel xClC‐5 expressed in <i>Xenopus laevis</i> oocytes and comparison with endogenous chloride currents (1998)

1. We recently cloned a putative chloride channel (xClC-5) from the renal cell line A6, which induced the appearance of a Cl- conductance not found in control oocytes after homologous expression in Xenopus oocytes. With the aim of increasing the Xenopus oocyte xClC-5 expression, we constructed a new plasmid in which the native 5' and 3' non-coding regions of xClC-5 were replaced by the non-coding regions of the Xenopus beta-globin sequence and in which a Kozak consensus site was introduced before the initiator ATG. 2. We then compared the induced currents Inative (induced by injection of cRNA presenting the native non-coding regions of xClC-5) and Ibeta-globin (induced by injection of cRNA presenting the non-coding regions of the Xenopus beta-globin sequence) investigating anion selectivity and anion blocker sensitivity. Several differences were found: (1) expression yield and oocyte surviving rate were largely increased by injecting (beta) xClC-5 cRNA, (2) the Ibeta-globin outward rectification score was 2.6 times that of Inative, (3) the anion conductivity sequence was nitrate > bromide > chloride > iodide >> gluconate for Ibeta-globin and iodide > bromide > nitrate > chloride >> gluconate for Inative, (4) 5-nitro-2-(3-phenylpropylamino)-benzoic acid (NPPB), anthracene-9-carboxylic acid (9-AC), DIDS, lanthanum ions, cAMP and ionomycin-induced [Ca2+]i increase inhibited Inative but had no effect on Ibeta-globin, and (5) Inative showed considerable similarity to the previously reported endogenous current appearing after ClC-6 or pICln cRNA injection. 3. Comparison of Inative with the endogenous chloride current ICl,swell which develops under hyposmotic conditions demonstrated several similarities in their electrophysiological and pharmacological characteristics but were nevertheless distinguishable. 4. In vitro translation assays demonstrated that protein synthesis was much greater using the (beta) xClC-5 construct than that of xClC-5. Furthermore, immunoreactivity of membrane preparations of Xenopus oocytes was only observed with the (beta) xClC-5 construct, its intensity being positively correlated with Ibeta-globin levels. 5. In addition, the current induced in (beta) xClC-5 cRNA-injected oocytes presented a very marked pH dependence (inhibition by acid external media) with a pKa value (negative log of the acid dissociation constant) of 5.67. 6. In conclusion, Ibeta-globin may be due to the presence of xClC-5 in the oocyte plasma membrane playing a role as an anion channel whereas Inative may represent an endogenous current induced by xClC-5 cRNA injection. The use of antibodies will facilitate the tissue and subcellular localization of xClC-5 and the identification of its physiological role.

Enhanced Arsenite Adsorption onto Litchi‐Like Al‐Doped Iron Oxides (2010)

Iron–aluminum complex hydroxide/oxides were synthesized from a hydrothermal process, and litchi‐like Al‐doped iron oxide nanoparticles were then obtained by removing extra boehmite nanoplates with NaOH washing. While the hydrothermal synthesis induced doping of iron oxide by Al, with the Al dopant concentration increasing with the Al–Fe molar ratio, removal of boehmite greatly increased the specific surface area (SSA) of these Al‐doped iron oxide nanoparticles. The resulting litchi‐like Al‐doped iron oxide nanoparticles were found to strongly adsorb As(III) from aqueous environment at neutral pH without preoxidation., and the As(III) (arsenite) adsorption capacity of Al‐doped iron oxides increased with the increase of the initial ratio of Al/Fe in the hydrothermal process, reaching as high as 2.5 times the adsorption capacity of pure iron oxide. The enhanced arsenite adsorption was shown to result from the increases in the amount of the surface hydroxyl group as well as in the SSA of Al‐doped iron oxide nanoparticles.
Dependencydiscovery for data integration (2013)

Data integration aims to combine data of dierent sources and to provide users with a unied view on these data.This task is as challenging as valuable.In this thesis we propose algorithms for dependency discovery to provide necessary information for data integration.We focus on inclusion dependencies (Inds) in general and a special form named conditional inclusion dependencies (Cinds): (i) Inds enable the discovery of structure in a given schema.(ii) Inds and Cinds support the discovery of cross-references or links between schemas.An Ind A B simply states that all values of attribute A are included in the set of values of attribute B. We propose an algorithm that discovers all inclusion dependencies in a relational data source.The challenge of this task is the complexity of testing all attribute pairs and further of comparing all of each attribute pair's values.The complexity of existing approaches depends on the number of attribute pairs, while ours depends only on the number of attributes.Thus, our algorithm enables to prole entirely unknown data sources with large schemas by discovering all Inds.Further, we provide an approach to extract foreign keys from the identied Inds.We extend our Ind discovery algorithm to also nd three special types of Inds:(i) Composite Inds, such as AB CD, (ii) approximate Inds that allow a certain amount of values of A to be not included in B, and (iii) prex and sux Inds that represent special cross-references between schemas.Conditional inclusion dependencies are inclusion dependencies with a limited scope dened by conditions over several attributes.Only the matching part of the instance must adhere the dependency.We generalize the denition of Cinds distinguishing covering and completeness conditions and dene quality measures for conditions.We propose ecient algorithms that identify covering and completeness conditions conforming to given quality thresholds.The challenge for this task is twofold: (i) Which (and how many) attributes should be used for the conditions?(ii) Which attribute values should be chosen for the conditions?Previous approaches rely on pre-selected condition attributes or can only discover conditions applying to quality thresholds of 100 %.Our approaches were motivated by two application domains: data integration in the life sciences and link discovery for linked open data.We show the eciency and the benets of our approaches for use cases in these domains.holder, Christoph Bhm, and Alexander Albrecht, who always provided support, suggestions, and fun in many lunch and coee talks and discussions.Finally, I thank my
The Modernization and Associated Restructuring of the National Weather Service: An Overview (1994)

The scientific understanding of the atmosphere and the ability to forecast large- and small-scale hydrometeorological phenomena have increased dramatically over the last two decades. As a result, the National Oceanic and Atmospheric Administration has set an ambitious goal: to modernize the National Weather Service (NWS) through the deployment of proven observational, information processing, and communications technologies, and to establish an associated cost-effective operational structure. The modernization and associated restructuring of the NWS will assure that the major advances that have been made in our ability to observe and understand the atmosphere are applied to the practical problems of providing atmospheric and hydrologic services to the nation. Implementation and practice of the new science will improve forecasts, provide more reliable detection of and warnings for severe weather and flooding, achieve more uniform hydrometeorological services across the nation, permit a more cost-effective NWS, and increase productivity among NWS employees. The changes proposed by the NWS will allow increased productivity and efficiency for any entity dependent on weather information, including local, state, and federal government agencies; researchers; private-sector meteorologists; private industry; and resource management organizations. This is the first in a series of articles intended to highlight these changes.
GSNP: A DNA Single-Nucleotide Polymorphism Detection System with GPU Acceleration (2011)

We have developed GSNP, a software package with GPU acceleration, for single-nucleotide polymorphism detection on DNA sequences generated from second-generation sequencing equipment. Compared with SOAPsnp, a popular, high-performance CPU-based SNP detection tool, GSNP has several distinguishing features: First, we design a sparse data representation format to reduce memory access as well as branch divergence. Second, we develop a multipass sorting network to efficiently sort a large number of small arrays on the GPU. Third, we compute a table of frequently used scores once to avoid repeated, expensive computation and to reduce random memory access. Fourth, we apply customized compression schemes to the output data to improve the I/O performance. As a result, on a server equipped with an Intel Xeon E5630 2.53 GHZ CPU and an NVIDIA Tesla M2050 GPU, it took GSNP about two hours to analyze a whole human genome dataset whereas the CPU-based, single-threaded SOAPsnp took three days for the same task on the same machine.

Current and emerging treatments for amyotrophic lateral sclerosis (2009)

Riluzole is the only compound that demonstrated a beneficial effect on ALS patients, but with only modest increase in survival. Although several drugs showed effective results in the animal models for ALS, none of them significantly prolonged survival or improved quality of life of ALS patients. Several factors have been implicated in explaining the predominantly negative results of numerous randomized clinical trials in ALS, including methodological problems in the use of animal-drug screening, the lack of assessment of pharmacokinetic profile of the drugs, and methodological pitfalls of clinical trials in ALS patients.

The Effects of Residual Chlorine;Temperatures and Salinities on the Mortality of Larval Milkfish Chanos Chanos (1989)

Seasonal variations of the extractive components of wild grass prawn,Penaeus monodon,caught along the coast of Tungkang,Pingtung in southernTaiwan were studied.Free amino acids,quaternary ammonium bases,nucleotide compounds,and inorganic compounds in the prawn's muscular tissue wereanalyzed.The major free amino acids included taurine,glutamine,proline,glycine,alanine,and arginine,of which glycine was the highest in content,followedby arginine.The content of glycine was higher in winter but lower in summer,while that of arginine was in reverse order.Variations on the contents ofthe other free amino acids were steady without indications of any highlysignificant seasonal change.The content of free amino acids was lowest in November,but highest inJanuary,with approximately 18-66% of the total extractive nitrogen.Contents of TMAO(trimethylamine oxide),glycine betaine and homarinewere highest among the quaternary ammonium bases and related compounds.The content of TMAO was highest during summer and autumn,but lowest inwinter.The content of glycine betaine was highest in July,but lowest inJanuary.Contents of glycine betaine and homarine varied greatly,but didnot change with the season.The total content of TMAO,glycine betaine andhomarine began to increase in April and peaked in August.The variation oftotal content was similar to that of arginine.Both decreased gradually andreached the minimum level in January.Nucleotides included IMP,AMP,GMP,ADP and ATP,with the first twoitems being the highest in content.Related compounds including hypoxanthineand inosine were scarce.The major inorganic compounds in the soluble extractive componentsincluded K(superscript +),Na(superscript +),Cl(superscript -),and PO(superscript 3-)4,with the last item being the highest.Thetotal content of inorganic compounds was rather high,ranking next to thecontent of free amino acids.The total contents of glycine,proline,alanine and serine were highestin winter,but lowest during summer and autumn.Therefore,grass prawn ismore palatable in winter than in summer.
