Probabilistic Models for Fine-Grained Truth Discovery from Crowdsourced Data (2015)

In crowdsourced data aggregation task, there exist conflicts in the answers provided by large numbers of sources on the same set of questions. The most important challenge for this task is to estimate source reliability and select answers that are provided by high-quality sources. Existing work solves this problem by simultaneously estimating sources' reliability and inferring questions' true answers (i.e., the truths). However, these methods assume that a source has the same reliability degree on all the questions, but ignore the fact that sources' reliability may vary significantly among different topics. To capture various expertise levels on different topics, we propose three fine-grained truth discovery models -- parametric probabilistic model (FaitCrowd), non-parametric probabilistic model and topical influence-aware model -- for the task of aggregating conflicting data collected from multiple users/sources. These probabilistic models jointly model the process of generating question content and sources' provided answers to estimate both fine-grained expertise and true answers simultaneously. This leads to a more precise estimation of source reliability. Therefore, theses models demonstrate better ability to obtain true answers for the questions compared with existing approaches.
Phenobarbitone in essential tremor (1985)

We conducted a double-blind, placebo-controlled trial of phenobarbitone on a fixed-dose regimen in 12 patients with essential tremor. The drug was better than placebo on accelerometric measurement and clinical assessment, but not according to patient self-assessment or measures of manual performance. Phenobarbitone may be an alternative to beta-adrenoreceptor antagonists in treating essential tremor.
An Unusual Ruthenium-Catalyzed Cycloisomerization of Alkynes and Propargyl Alcohols (2002)

CpRu(NCCH3)3+PF6- catalyzes the cycloisomerization of diyne-ols to alpha,beta,gamma,delta-unsaturated aldehydes and ketones in good-to-excellent yields. 1-Hydroxy-2,7-diynes and 1-hydroxy-2,8-diynes can be utilized to form highly functionalized five- and six-membered rings, respectively. Tertiary as well as secondary propargyl alcohols are cycloisomerized to a single isomeric product. A wide variety of tether substitution can be tolerated. Even totally unsubstituted tethers can be employed, as geminal disubstituents are not required for cyclization. Additional hydroxyl substituents at an alternative "internal" propargylic position are eliminated during the reaction-a feature that leads to a convenient cyclopentadiene synthesis. Furthermore, 3-hydroxy-1,6-diynes also can be cyclized to form cross-conjugated aldehydes.
Static timing: Back to our roots (2008)

Existing static timing methodologies apply various techniques to address increasingly larger process variations. The techniques include multi-corner timing, on-chip variation (OCV) derating coefficients, and path-based common path pessimism removal (CPPR) procedures. These techniques, however, destroy the benefits of linear run-time and incrementality possessed by classical static timing. The major contribution of this work is an efficient statistical timing methodology with comprehensive modeling of process variations, while at the same time retaining those key benefits. Our methodology is compatible with existing characterization methods and scales well to large chip designs. To achieve this goal, three techniques are developed: (1) building the statistical delay model based on existing multi-corner library characterization; (2) modeling spatial correlation in a scalable manner; and (3) avoiding the time-consuming CPPR procedure by removing common path pessimism in the clock network by an incremental block-based technique. Experimental results on industrial 90 nm ASIC designs show that the proposed timing methodology correctly handles all types of process variation, achieves high correlation with traditional multi-corner timing with more than 4 × speedup, and is a vehicle for pessimism reduction.
On Prosecuting Presidents (1999)

In 1996, my student Brian Kalt and I co-authored an article explaining that a sitting President is constitutionally immune from ordinary criminal prosecution-state or federal-but is of course subject to ordinary prosecution the instant he leaves office, a prospect that can obviously be hastened by impeachment. In this Essay, I shall summarize my reasons for continuing to believe this.
Defining the Role of Phosphomethylethanolamine <i>N</i>-Methyltransferase from <i>Caenorhabditis elegans</i> in Phosphocholine Biosynthesis by Biochemical and Kinetic Analysis (2006)

In plants and Plasmodium falciparum, the synthesis of phosphatidylcholine requires the conversion of phosphoethanolamine to phosphocholine by phosphoethanolamine methyltransferase (PEAMT). This pathway differs from the metabolic route of phosphatidylcholine synthesis used in mammals and, on the basis of bioinformatics, was postulated to function in the nematode Caenorhabditis elegans. Here we describe the cloning and biochemical characterization of a PEAMT from C. elegans (gene, pmt-2; protein, PMT-2). Although similar in size to the PEAMT from plants, which contain two tandem methyltransferase domains, PMT-2 retains only the C-terminal methyltransferase domain. RNA-mediated interference experiments in C. elegans show that PMT-2 is essential for worm viability and that choline supplementation rescues the RNAi-generated phenotype. Unlike the plant and Plasmodium PEAMT, which catalyze all three methylations in the pathway, PMT-2 catalyzes only the last two steps in the pathway, i.e., the methylation of phosphomonomethylethanolamine (P-MME) to phosphodimethylethanolamine (P-DME) and of P-DME to phosphocholine. Analysis of initial velocity patterns suggests a random sequential kinetic mechanism for PMT-2. Product inhibition by S-adenosylhomocysteine was competitive versus S-adenosylmethionine and noncompetitive versus P-DME, consistent with formation of a dead-end complex. Inhibition by phosphocholine was competitive versus each substrate. Fluorescence titrations show that all substrates and products bind to the free enzyme. The biochemical data are consistent with a random sequential kinetic mechanism for PMT-2. This work provides a kinetic basis for additional studies on the reaction mechanism of PEAMT. Our results indicate that nematodes also use the PEAMT pathway for phosphatidylcholine biosynthesis. If the essential role of PMT-2 in C. elegans is conserved in parasitic nematodes of mammals and plants, then inhibition of the PEAMT pathway may be a viable approach for targeting these parasites with compounds of medicinal or agronomic value.
Model-Based Probabilistic Collision Detection in Autonomous Driving (2009)

The safety of the planned paths of autonomous cars with respect to the movement of other traffic participants is considered. Therefore, the stochastic occupancy of the road by other vehicles is predicted. The prediction considers uncertainties originating from the measurements and the possible behaviors of other traffic participants. In addition, the interaction of traffic participants, as well as the limitation of driving maneuvers due to the road geometry, is considered. The result of the presented approach is the probability of a crash for a specific trajectory of the autonomous car. The presented approach is efficient as most of the intensive computations are performed offline, which results in a lean online algorithm for real-time application.
The use of medicines in a comparative study across European interview-based surveys (2002)

This paper examines the approach to consumption of medicines in interview-based surveys across seven countries of the European Union. The goals of the study are to provide information on the accurateness of different surveys for microeconomic analysis of pharmaceutical demand offered by Household Budget Surveys and National Health Surveys, and to illustrate the limitations of these data sources in cross-population comparability of information.
Enhancing the Coping Skills of Mothers with Developmentally Delayed Children (1991)

Recent studies have shown that mothers of developmentally delayed children are at risk for depression. During weekly psychoeducational group meetings, Roy's adaptation model was used to identify the focal, contextual, and residual stimuli that contributed to the mothers' depression. Nursing interventions that encouraged adaptation in the four modes were implemented by group facilitators providing parent education and emotional support. Implications for nurses in a variety of settings are given.
nPEG-TiO<sub>2</sub> Nanoparticles: A Facile Route to Elaborate Nanostructured Surfaces for Biological Applications (2011)

We report the synthesis of diacid-terminated PEG-functionalized cubic TiO2 nanocrystals by a simple one-step solvothermal method, and their further use to form nanostructured surfaces for protein immobilization. The relevance and major interest of the so-obtained nanocrystals are the presence of terminal carboxylic acid groups at their surface, as confirmed by infrared analyses, in addition to the surrounding PEG chains, essential to avoid non specific interactions. These functional chemical groups were used to (i) immobilize the synthesized nanocubes on a cysteamine-modified Au surface, and to (ii) attach proteins via a presumable covalent link. AFM images show that the shapes and the narrow size distribution of the nanocubes, observed by TEM, were preserved after their immobilization on the modified Au surface. Moreover, the efficiency and specificity of antigen recognition were demonstrated using spectroscopic analyses. Our successful approach provides a versatile and facile way to elaborate specific and sensitive nanostructured surfaces for biosensors.
Scalable and Efficient Bounds Checking for Large-Scale CMP Environments (2011)

We attempt to provide an architectural support for fast and efficient bounds checking for multithread work-loads in chip-multiprocessor (CMP) environments. Bounds information sharing and smart tagging help to perform bounds checking more effectively utilizing the characteristics of a pointer. Also, the BCache architecture allows fast access to the bounds information. Simulation results show that the proposed scheme increases <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">μ</sub> PC of memory operations by 29% on average compared to the previous hardware scheme.
On feed-forward and feedback timing recovery for digital magnetic recording systems (1991)

Two different timing recovery techniques, namely, feedforward and feedback, for digital magnetic recording systems are compared. The feedforward approach uses nonlinear filtering to derive the timing information, whereas the feedback approach relies on detected symbols from a suitably equalized signal. The steady-state performance of these timing recovery methods is compared under the same operating conditions. It is shown that the feedforward method provides superior performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
On the Security of a Multi-use CCA-Secure Proxy Re-encryption Scheme (2012)

In proxy re-encryption (PRE), a semi-trusted proxy can convert a cipher text originally intended for Alice into one which can be decrypted by Bob, while the proxy can not know the corresponding plaintext. PREcan be classified as single-use PRE and multi-use PRE according to the times the cipher text can be transformed. In multi-use PRE schemes, the cipher text can be transformed from A to B and to C and so on. In CCS'09 (post session), Wan get al. proposed a multi-use unidirectional CCA-secure proxy re-encryption scheme. Unfortunately, we show their proposal is not CCA-secure in the corresponding security models by giving concrete attacks.
A cylindrical coil with graduated current density for very homogeneous magnetic fields (1972)

A new method of obtaining a very homogeneous magnetic field compensated to the sixth order is suggested. This is achieved by lowering the current density in the central part of a simple cylindrical coil. The optimum volume of the necessary conductor for such a coil is smaller than for a so called outer notch coil compensated to the sixth order. The new type of homogeneous coils could be very advantageous for high field superconducting solenoids. An example is given of a 6 T superconducting solenoid with an inner diameter of 3.2 cm with a field homogeneity better than 10-6 throughout a spherical volume of 1 cm diameter, which requires 10% less superconductor than a notched coil.
Neuromorphic semiconductor memory (2015)

Microprocessors designed with von Neumann architecture are hitting the power and performance limits as silicon CMOS continues to scale the critical dimensions of the circuit components towards single digit nanometer size limit. Multi-core processor, parallel processing without increasing operating frequency of the cores, was introduced in the early 2000 to extend the power and performance scaling, keeping Moore's Law viable. Evolution has provided us with the most efficient parallel processing architecture: the biological brain. In this talk, we shall examine what we can do with little that we know about how the brain works to design machines to mimic the brain's memory.
Activation of Endothelial Cells, Coagulation and Fibrinolysis in Thai Children with Dengue Virus Infection. (2005)

Abstract Dengue virus is an arthropod borne flavivirus that most commonly causes a non-specific febrile illness: Dengue Fever (DF), and less frequently causes a life-threatening illness: Dengue Hemorrhagic Fever (DHF). The fatality rates of DHF are varying from 1 to 5% in tropical countries. Although severe bleeding remains the major cause of death, the pathogenesis of bleeding is poorly understood. This study was primarily designed to determine the extent of activation of endothelial cells, coagulation cascade and fibrinolysis in correlation with clinical severity and also to detect the best prognostic factor(s) for DHF during the febrile phase. We conducted a prospective cohort study in 42 children with Dengue infections (20 with DF and 22 with DHF); 38 age-matched normal Thai children served as the control group. Endothelial cell activation, coagulation and fibrinolysis parameters were measured in each patient during 3 phases of illness: febrile (Days 1–4), toxic (Days 5–6) and convalescent (Day 7–10). Bleeding scores (Buchanan G, et al, J Pediatr 2002) were also classified. Results: In DHF patients, during the febrile phase, plasma levels of von Willebrand Factor Antigen (VWF:Ag), tissue factor (TF), Thrombin-Antithrombin Complex (TAT), and D-dimer were significantly high, while platelet counts, fibrinogen, Protein C activity (PC:Ac) and thrombin activatable fibrinolysis inhibitor (TAFIa) were significantly low compared to the control group. During the toxic phase, activated Factor VII (FVIIa:c), tissue plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI-1) were significantly increased compared to the control group. In DF patients, during the febrile phase, only plasma levels of VWF:Ag were significantly elevated, while platelet count, PC:Ac and TAFIa were significantly lowered compared to the control group. During the toxic phase, soluble thrombomodulin (sTM), FVIIa:c, and TAT were significantly raised compared to the control group. Compared to DF patients, DHF patients had significantly higher plasma concentrations of vWF:Ag (p=0.02), TF (p=0.01), and PAI-1 (p=0.038) during the febrile phase. Bleeding scores were positively correlated with plasma t-PA and clinical severity, and negatively correlated with plasma Factor VIII:C and TAFIa. Using logistic regression analysis, we found that an increase in plasma VWF:Ag was the only significant predictor (p=0.049) of progression to DHF. The endothelial cell injury and release of procoagulant components, activation of the coagulation cascade with thrombin generation, increased antifibrinolytic factors and consumption of natural anticoagulants each play important roles in the development of hemorrhage in Dengue patients. Plasma VWF:Ag is the best indicator of progression to DHF.

Foxo Factors: A Matter of Life and Death (2006)

Forkhead box O-class (FOXO) transcription factors, including FOXO1, FOXO3a and FOXO4, function as tumor-suppressor proteins by inhibiting cell proliferation, promoting apoptotic cell death and protecting cells from DNA damage and oxidative stress. The potency of these functions is regulated tightly by phosphorylation, acetylation and ubiquitination. Emerging evidence indicates that protein levels of FOXO1 are under dual regulation by Ak-mediated phosphorylation and Skp2-mediated ubiquitination. Given that Akt and Skp2 proteins are highly activated in human cancers due to the loss of phosphatase and tensin homolog (PTEN), deregulation of the FOXO1 protein appears to be a promising target for future drug discovery and cancer therapy.
Multi-heads Attention Graph Convolutional Networks for Skeleton-Based Action Recognition (2019)

Compared with video-based action recognition, skeleton-based methods have more compact and accurate representation. In the recent development, human skeleton is modeled as graph and graph-based deep learning method is applied for recognition. Generally, in actions, few joints are pivotal other than the whole body, like waving hands mostly related with hand and arm joints. Hence, we propose the data-driven multi-head attention model for graph convolutional networks. The attention model identifies key joints of every action by introducing two regularization terms, i.e., spatial diversity and local continuity. Further, we introduce the joint-wise second order motion information as the additional feature on the graph node, which represents the motion variation explicitly. We have tested our methods on the largest popular dataset, NTU-RGB+D, and we reach state-of-the-art performance.
A low-cost, color-calibrated reflective high dynamic range display (2010)

High dynamic range (HDR) displays are enabling new advances in visual psychophysics, but commercial HDR displays are both expensive, and difficult to calibrate colorimetrically. Homebrew HDR displays incorporating LCD panels and digital projectors are relatively inexpensive and can be calibrated, but building such displays requires sophisticated technical skills. We have developed a low-cost, color-calibrated HDR display for vision research that can be constructed and used by researchers without the need for specialized equipment or advanced engineering abilities. Inspired by the work of Bimber et al., this reflective HDR display incorporates an inkjet printer, a digital video projector and a digital camera. To display an HDR image, the image is first processed through the iCAM06 image appearance model to produce a standard dynamic range (SDR) image that is sent to the printer. The digital video projector is then roughly positioned so its image field covers the print. Custom camera-based structured-light image registration software then automatically aligns the projected and printed images. A color calibration module then measures the print colors and determines the values to send to the projector to achieve the best possible reproduction of the original HDR image. This iCAM-based approach to HDR color reproduction goes substantially beyond prior work in terms of its colorimetric accuracy. With respect to intensity and dynamic range, because the print area is substantially smaller than a projector's typical field size, the maximum intensity in the combined image can be quite high, and the current display has a peak luminance around 2000 cd/m2 with a dynamic range greater than 20,000:1. While the print-based nature of this display does limit its usefulness for interactive studies, its low-cost, do-it-yourself design, and its ability to be calibrated should make it a valuable addition to the vision researcher's laboratory.
Rare Earth Elements: The Global Supply Chain (2013)

The concentration of production of rare earth elements (REEs) outside the United States raises the important issue of supply vulnerability. REEs are used for new energy technologies and national security applications. This report provides a discussion on the major issues and concerns of the global supply chain for rare earth elements, their major end uses, and legislative and other policy proposals that Congress may consider to improve the U.S. rare earth position.
