Experiments on Domain Adaptation for English--Hindi SMT (2009)

Abstract. Statistical Machine Translation (SMT) systems are usually trained on large amounts of bilingual text and monolingual target language text. If a significant amount of out-of-domain data is added to the training data, the quality of translation can drop. On the other hand, training an SMT system on a small amount of training material for given indomain data leads to narrow lexical coverage which again results in a low translation quality. In this paper, (i) we explore domain-adaptation techniques to combine large out-of-domain training data with small-scale in-domain training data for English—Hindi statistical machine translation and (ii) we cluster large out-of-domain training data to extract sentences similar to in-domain sentences and apply adaptation techniques to combine clustered sub-corpora with in-domain training data into a unified framework, achieving a 0.44 absolute corresponding to a 4.03 % relative improvement in terms of BLEU over the baseline.
Integrated Longitudinal and Lateral Tire/Road Friction Modeling and Monitoring for Vehicle Motion Control (2006)

A proper tire friction model is essential to model overall vehicle dynamics for simulation, analysis, or control purposes since a ground vehicle's motion is primarily determined by the friction forces transferred from roads via tires. Motivated by the developments of high-performance antilock brake systems (ABSs), traction control, and steering systems, significant research efforts had been put into tire/road friction modeling during the past 40 years. In this paper, a review of recent developments and trends in this area is presented, with attempts to provide a broad perspective of the initiatives and multidisciplinary techniques for related research. Different longitudinal, lateral, and integrated tire/road friction models are examined. The associated friction-situation monitoring and control synthesis are discussed with a special emphasis on ABS design
Confidence Conditioned Knowledge Distillation (2021)

In this paper, a novel confidence conditioned knowledge distillation (CCKD) scheme for transferring the knowledge from a teacher model to a student model is proposed. Existing state-of-the-art methods employ fixed loss functions for this purpose and ignore the different levels of information that need to be transferred for different samples. In addition to that, these methods are also inefficient in terms of data usage. CCKD addresses these issues by leveraging the confidence assigned by the teacher model to the correct class to devise sample-specific loss functions (CCKD-L formulation) and targets (CCKD-T formulation). Further, CCKD improves the data efficiency by employing self-regulation to stop those samples from participating in the distillation process on which the student model learns faster. Empirical evaluations on several benchmark datasets show that CCKD methods achieve at least as much generalization performance levels as other state-of-the-art methods while being data efficient in the process. Student models trained through CCKD methods do not retain most of the misclassifications commited by the teacher model on the training set. Distillation through CCKD methods improves the resilience of the student models against adversarial attacks compared to the conventional KD method. Experiments show at least 3% increase in performance against adversarial attacks for the MNIST and the Fashion MNIST datasets, and at least 6% increase for the CIFAR10 dataset.
Efficient assembly of rat hepatocyte spheroids for tissue engineering applications (1996)

Freshly harvested primary rat hepatocytes cultivated as multicellular aggregates, or spheroids, have been observed to exhibit enhanced liver-specific function and differentiated morphology compared to cells cultured as monolayers. An efficient method of forming spheroids in spinner vessels is described. Within 24 h after inoculation, greater than 80% of inoculated cells formed spheroids. This efficiency was significantly greater than that reported previously for formation in stationary petri dishes. With a high specific oxygen uptake rate of 2.0 x 10(-9) mmol O(2)/cell/h, the oxygen supply is critical and should be monitored for successful formation. Throughout a 6-day culture period, spheroids assembled in spinner cultures maintained a high viability and produced albumin and urea at constant rates. Transmission electron microscopy indicated extensive cell-cell contacts and tight junctions between cells within spheroids. Microvilli-lined bile canaliculus-like channels were observed in the interior of spheroids and appeared to access the exterior through pores at the outer surface. Spheroids from spinner cultures exhibited at least the level of liver-specific activity as well as similar morphology and ultrastructure compared to spheroids formed in stationary petri dishes. Hepatocytes cultured as spheroids are potentially useful three-dimensional cell systems for application in a bioartificial liver device and for studying xenobiotic drug metabolism.

Prony Analysis for Power System Transient Harmonics (2007)

Proliferation of nonlinear loads in power systems has increased harmonic pollution and deteriorated power quality. Not required to have prior knowledge of existing harmonics, Prony analysis detects frequencies, magnitudes, phases, and especially damping factors of exponential decaying or growing transient harmonics. In this paper, Prony analysis is implemented to supervise power system transient harmonics, or time-varying harmonics. Further, to improve power quality when transient harmonics appear, the dominant harmonics identified from Prony analysis are used as the harmonic reference for harmonic selective active filters. Simulation results of two test systems during transformer energizing and induction motor starting confirm the effectiveness of the Prony analysis in supervising and canceling power system transient harmonics.
Switch-Level Delay Models for Digital MOS VLSI (1984)

This paper presents fast, simple, and relatively accurate delay models for large digital MOS circuits. Delay modeling is organized around chains of switches and nodes called stages, instead of logic gates. The use of stages permits both logic gates and pass transistor arrays to be handled in a uniform fashion. Three delay models are presented, ranging from an RC model that typically errs by 25% to a slope-based model whose delay estimates are typically within 10% of SPICE's estimates. The slope model is parameterized in terms of the ratio between the slopes of a stage's input and output waveforms. All the models have been implemented in the Crystal timing analyzer. They are evaluated by comparing their delay estimates to SPICE, using a dozen critical paths from two VLSI designs.
The EVERSHED receptor-like kinase modulates floral organ shedding in<i>Arabidopsis</i> (2010)

Plant cell signaling triggers the abscission of entire organs, such as fruit, leaves and flowers. Previously, we characterized an ADP-ribosylation factor GTPase-activating protein, NEVERSHED (NEV), that regulates membrane trafficking and is essential for floral organ shedding in Arabidopsis. Through a screen for mutations that restore organ separation in nev flowers, we have identified a leucine-rich repeat receptor-like kinase, EVERSHED (EVR), that functions as an inhibitor of abscission. Defects in the Golgi structure and location of the trans-Golgi network in nev abscission zone cells are rescued by a mutation in EVR, suggesting that EVR might regulate membrane trafficking during abscission. In addition to shedding their floral organs prematurely, nev evr flowers show enlarged abscission zones. A similar phenotype was reported for plants ectopically expressing INFLORESCENCE DEFICIENT IN ABSCISSION, a predicted signaling ligand for the HAESA/HAESA-LIKE2 receptor-like kinases, indicating that this signaling pathway may be constitutively active in nev evr flowers. We present a model in which EVR modulates the timing and region of abscission by promoting the internalization of other receptor-like kinases from the plasma membrane.
Patient-physician relationships in the information age. (2000)

The ready and free availability of information that characterizes the Information Age--with health information on the Internet and direct-to-consumer advertising of prescription drugs as two of these major information sources--is bringing about significant changes in patient-physician relationships. By developing a matrix of intended and unintended consequences and desirable and undesirable consequences, it's possible to have a better understanding of the impact of the free flow of information on this traditional relationship. Ultimately, any marketing approach to these newly empowered patients must take their level of health care knowledge into consideration.
Simulation research of H &#x221E; filter for the pitch control of AUV (2010)

A H ∞ filter is proposed to suppress the adverse effects generated by the measurement noise in the pitch control system of an autonomous underwater vehicle. A kinetic model of AUV's pitch motion in vertical plane is established by linearizing the nonlinear model at a specified operating point. Based on LMI Lab, it is possible to design a global optimal H <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</inf> filter for an accurate estimation of the contaminated states which are very important inputs to the feedback controller. It is reported that this filter is effective to eliminate the negative effects caused by measurement noise. And the accurate estimation to the system states means a lot for systems lacking disparate measurement.

Placental Perivascular Cells for Human Muscle Regeneration (2010)

Perivascular multipotent mesenchymal progenitors exist in a variety of tissues, including the placenta. Here, we suggest that the abundant vasculature present in the human placenta can serve as a source of myogenic cells to regenerate skeletal muscle. Chorionic villi dissected from the mid-gestation human placenta were first transplanted intact into the gastrocnemius muscles of SCID/mdx mice, where they participated in muscle regeneration by producing myofibers expressing human dystrophin and spectrin. In vitro-cultured placental villi released rapidly adhering and migratory CD146+CD34⁻CD45⁻CD56⁻ cells of putative perivascular origin that expressed mesenchymal stem cell markers. CD146+CD34⁻CD45⁻CD56⁻ perivascular cells isolated and purified from the placental villi by flow cytometry were indeed highly myogenic in culture, and generated dystrophin-positive myofibers, and they promoted angiogenesis after transplantation into SCID/mdx mouse muscles. These observations confirm the existence of mesenchymal progenitor cells within the walls of human blood vessels, and suggest that the richly vascularized human placenta is an abundant source of perivascular myogenic cells able to migrate within dystrophic muscle and regenerate myofibers.

Unusual odd-electron fragments from even-electron protonated prodiginine precursors using positive-ion electrospray tandem mass spectrometry (2008)

Reports of anticancer and immunosuppressive properties have spurred recent interest in the bacterially produced prodiginines. We use electrospray tandem mass spectrometry (ES-MS/MS) to investigate prodigiosin, undecylprodiginine, and streptorubin B (butyl-meta-cycloheptylprodiginine) and to explore their fragmentation pathways to explain the unusual methyl radical loss and consecutive fragment ions that dominate low-energy collision-induced dissociation (CID) mass spectra. The competition between the formation of even-electron ions and radical ions is examined in detail. Theoretical calculations are used to optimize the structures and calculate the energies of both reactants and products using the Gaussian 03 program. Results indicate that protonation occurs on the nitrogen atom that initially held no hydrogen, thus allowing formation of a pseudo-seven-membered ring that constitutes the most stable ground state [M + H](+) structure. From this precursor, experimental data show that methyl radical loss has the lowest apparent threshold but, alternatively, even-electron fragment ions can be formed by loss of a methanol molecule. Computational modeling indicates that methyl radical loss is the more endothermic process in this competition, but the lower apparent threshold associated with methyl radical loss points to a lower kinetic barrier. Additionally, this characteristic and unusual loss of methyl radical (in combination with weaker methanol loss) from each prodiginine is useful for performing constant neutral loss scans to quickly and efficiently identify all prodiginines in a complex biological mixture without any clean-up or purification. The feasibility of this approach has been proven through the identification of a new, low-abundance prodigiosin analog arising from Hahella chejuensis.
Short Term Glucose Homeostasis in Man: A Systems Dynamics Model (1973)

A model of glucose homeostasis whose behavior resembles clinically observed behavior is subjected to a variety of glucose stimuli. This model is used to focus attention on the mechanism of insulin secretion as related to the duration of glucose infusion during the standard intravenous glucose test (0.5 gm/kg body weight). An important clinical experiment was suggested and performed—the duration of glucose infusion was increased from 3 minutes to 12 minutes. An initial peak of insulin is observed at 4 to 6 minutes after the beginning of the infusion. This is followed by a fall in insulin levels while the glucose continues to rise. Because of this experiment, the initial model of glucose homeostasis has undergone changes to include circulatory and transport dynamics and altered mechanisms of insulin release and liver clearance of both glucose and insulin.
Identification of ASK10 as a Multicopy Activator of Skn7p‐dependent Transcription of a HIS3 Reporter Gene (1996)

Recent evidence has demonstrated that the yeast Skn7p appears to act as a ‘response regulator’ in a eukaryotic ‘two-component’ signal transduction pathway. A search to identify possible regulators of the SKN7 mediated ‘two- component’ regulatory system has identified Ask10p as a novel potential transcription factor. The ASK10 sequence has been deposited in GenBank with Accession Number U27209.
Comparison of PVDF- and FEP-based radiation-grafted alkaline anion-exchange membranes for use in low temperature portable DMFCs (2002)

Vinylbenzyl chloride has been radiation grafted onto both PVDF and FEP fluoropolymer films; subsequent amination and ion-exchange to give the hydroxide ion forms yield anion-exchange membranes suitable for use in low temperature direct methanol fuel cells for portable applications.
Perspective Distortion from Interpersonal Distance Is an Implicit Visual Cue for Social Judgments of Faces (2012)

The basis on which people make social judgments from the image of a face remains an important open problem in fields ranging from psychology to neuroscience and economics. Multiple cues from facial appearance influence the judgments that viewers make. Here we investigate the contribution of a novel cue: the change in appearance due to the perspective distortion that results from viewing distance. We found that photographs of faces taken from within personal space elicit lower investments in an economic trust game, and lower ratings of social traits (such as trustworthiness, competence, and attractiveness), compared to photographs taken from a greater distance. The effect was replicated across multiple studies that controlled for facial image size, facial expression and lighting, and was not explained by face width-to-height ratio, explicit knowledge of the camera distance, or whether the faces are perceived as typical. These results demonstrate a novel facial cue influencing a range of social judgments as a function of interpersonal distance, an effect that may be processed implicitly.
Effect of natural radioactivity on optical fibers of undersea cables (1996)

For undersea cables radiation doses between 2.5 and 25 rad are to be expected during a working life of 25 years. The majority of previous investigations of the radiation sensitivity of optical fibers, however, apply dose rates /spl gsim/1 rad/s and total dose values /spl gsim/3/spl times/10/sup 3/ rad. The present paper describes /sup 60/Co irradiations of a Ge-doped single mode fiber with dose rates between 10/sup -4/ and 20 rad/s. Expected loss increase of an undersea optical fiber cable at 1550 nm wavelength with a temperature of 2/spl deg/C is derived by three different methods. The most comfortable and reliable one, the 'dose rate transformation method', yields, for example, a loss of only 0.0244 dB/100 km after 25 years of irradiation with a dose rate of 0.4 rad/s. This method could be the basis of a standard test procedure for the effect of natural radioactivity on optical fibers for very long repeaterless terrestrial and undersea cables.
Direction of arrival estimation for speech sources using fourth order cross cumulants (2008)

In many applications where speech separation and enhancement is of interest, e.g. conferencing systems, mobile phones and hearing aids, accurate speaker localization is important. This paper presents an alternative criteria for the well known steered response power with phase transform (SRP-PHAT) algorithm, in which the steered response relates to peaks in the fourth order cross cumulant, rather than peaks in the second order cross cumulant, i.e. the cross power spectrum. Since speech sources have a probability density function (PDF) close to the Laplacian distribution and noise are generally closer to the Gaussian distribution, the fourth order cumulant becomes a good alternative for the steered response search for speech sources. The proposed method is evaluated and compared to the original SRP-PHAT algorithm and shows significant improvements in localization performance for speech sources.

Particle swarm optimization applied to integrated demand response resources scheduling (2011)

The concept of demand response has a growing importance in the context of the future power systems. Demand response can be seen as a resource like distributed generation, storage, electric vehicles, etc. All these resources require the existence of an infrastructure able to give players the means to operate and use them in an efficient way. This infrastructure implements in practice the smart grid concept, and should accommodate a large number of diverse types of players in the context of a competitive business environment. In this paper, demand response is optimally scheduled jointly with other resources such as distributed generation units and the energy provided by the electricity market, minimizing the operation costs from the point of view of a virtual power player, who manages these resources and supplies the aggregated consumers. The optimal schedule is obtained using two approaches based on particle swarm optimization (with and without mutation) which are compared with a deterministic approach that is used as a reference methodology. A case study with two scenarios implemented in DemSi, a demand Response simulator developed by the authors, evidences the advantages of the use of the proposed particle swarm approaches.
Stochastic Protein Interactions Monitored by Hundreds of Single-Molecule Plasmonic Biosensors (2015)

We present a plasmonic biosensor based on hundreds of individual gold nanorods with single-molecule sensitivity that are simultaneously monitored in real-time within a dark-field microscopy setup. The approach allows for the statistical analysis of single-molecule interactions without requiring any labeling of the analyte. We study an antibody-antigen interaction and find that the waiting-time distribution is concentration-dependent and obeys Poisson statistics. The ability to probe hundreds of nanoparticles simultaneously will provide a sensor with a dynamic range of 7 decades in concentration and will enable the study of heterogeneity in molecular interactions.

Integration of multi-level self-aligned CoWP barrier compatible with high performance BEOL (2006)

A hybrid CoWP/SiCN Cu passivation was integrated in a three-metal-level interconnect stack at 65 nm technology node using a porous ULK material (K=2.5). 5 and 20 nm thick Pd-free CoWP electroless barriers were evaluated using a standard trench first hard mask architecture (TFHM) integration scheme, with PVD, ALD or punch-through Ta-based metallization processes. This study evidenced strong interaction between CoWP and etching chemistries, inducing feature size modification. Results evidenced the successful integration of an ultra-thin electroless barrier with slight process tuning, whereas thicker one still requires specific etch process development or integration scheme modification
