Animating blendshape faces by cross-mapping motion capture data (2006)

Animating 3D faces to achieve compelling realism is a challenging task in the entertainment industry. Previously proposed face transfer approaches generally require a high-quality animated source face in order to transfer its motion to new 3D faces. In this work, we present a semi-automatic technique to directly animate popularized 3D blendshape face models by mapping facial motion capture data spaces to 3D blendshape face spaces. After sparse markers on the face of a human subject are captured by motion capture systems while a video camera is simultaneously used to record his/her front face, then we carefully select a few motion capture frames and accompanying video frames as reference mocap-video pairs. Users manually tune blendshape weights to perceptually match the animated blendshape face models with reference facial images (the reference mocap-video pairs) in order to create reference mocap-weight pairs. Finally, the Radial Basis Function (RBF) regression technique is used to map any new facial motion capture frame to blendshape weights based on the reference mocap-weight pairs. Our results demonstrate that this technique is efficient to animate blendshape face models, while offering its generality and flexiblity.
Two Kdo-Heptose Regions Identified in<i>Hafnia alvei</i>32 Lipopolysaccharide: the Complete Core Structure and Serological Screening of Different<i>Hafnia</i>O Serotypes (2008)

Hafnia alvei, a gram-negative bacterium, is an opportunistic pathogen associated with mixed hospital infections, bacteremia, septicemia, and respiratory diseases. Various 3-deoxy-d-manno-oct-2-ulosonic acid (Kdo)-containing fragments different from known structures of core oligosaccharides were previously found among fractions obtained by mild acid hydrolysis of some H. alvei lipopolysaccharides (LPSs). However, the positions of these segments in the LPS structure were not known. Analysis of de-N,O-acylated LPS by nuclear magnetic resonance spectroscopy and mass spectrometry allowed the determination of the location of a Kdo-containing trisaccharide in the structure of H. alvei PCM 32 LPS. It was established that the trisaccharide {L-alpha-D-Hepp-(1-->4)-[alpha-D-Galp6OAc-(1-->7)]-alpha-Kdop-(2-->} is an integral part of the outer-core oligosaccharide of H. alvei 32 LPS. The very labile ketosidic linkage between -->4,7)-alpha-Kdop and -->2)-Glcp in the core oligosaccharide was identified. Screening for this Kdo-containing trisaccharide was performed on the group of 37 O serotypes of H. alvei LPSs using monospecific antibodies recognizing the structure. It was established that this trisaccharide is a characteristic component of the outer-core oligosaccharides of H. alvei 2, 32, 600, 1192, 1206, and 1211 LPSs. The weaker cross-reactions with LPSs of strains 974, 1188, 1198, 1204, and 1214 suggest the presence of similar structures in these LPSs, as well. Thus, we have identified new examples of endotoxins among those elucidated so far. This type of core oligosaccharide deviates from the classical scheme by the presence of the structural Kdo-containing motif in the outer-core region.
A buried capacitor DRAM cell with bonded SOI for 256 M and 1 Gbit DRAMs (1992)

This paper describes a novel DRAM cell structure using bonded SOI. The cell capacitor is flexibly formed like a stack-capacitor, but buried under the silicon layer. Thus, both a large Cs and small cell size are obtained. Moreover, using a PMOS cell transistor whose back-surface is shielded by a cell plate, the cell leakage current is reduced to 1 fA/cell, resulting in good data retention. Accordingly, a simple scaling of this structure realizes 256 M and 1 Gbit DRAMs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis and Electrochemical and Biological Studies of Novel Coumarin–Chalcone Hybrid Compounds (2013)

A series of novel hydroxy-coumarin-chalcone hybrid compounds 2a-i has been synthesized by employing a simple and efficient methodology. An electrochemical characterization using cyclic voltammetry and ESR spectroscopy were carried out to characterize the oxidation mechanism for the target compounds. The antioxidant capacity and reactivity were determined by ORAC and ESR assays, respectively. Biological assays were assessed to evaluate the cytotoxicity and cytoprotection capacity against ROS/RNS on BAEC. The results revealed that all tested compounds present ORAC values that are much higher than other well-known antioxidant compounds such as quercetin and catechin. Compound 2e showed the highest ORAC value (14.1) and also presented a low oxidation potential, good scavenging capacity against hydroxyl radicals, low cytotoxicity, and high cytoprotective activity.

Gold Nanorod Induced Warming of Embryos from the Cryogenic State Enhances Viability (2017)

Zebrafish embryos can attain a stable cryogenic state by microinjection of cryoprotectants followed by rapid cooling, but the massive size of the embryo has consistently led to failure during the convective warming process. Here we address this zebrafish cryopreservation problem by using gold nanorods (GNRs) to assist in the warming process. Specifically, we microinjected the cryoprotectant propylene glycol into zebrafish embryos along with GNRs, and the samples were cooled at a rate of 90 000 °C/min in liquid nitrogen. We demonstrated the ability to unfreeze the zebrafish rapidly (1.4 × 10<sup>7</sup> °C/min) by irradiating the sample with a 1064 nm laser pulse for 1 ms due to the excitation of GNRs. This rapid warming process led to the outrunning of ice formation, which can damage the embryos. The results from 14 trials (n = 223) demonstrated viable embryos with consistent structure at 1 h (31%) and continuing development at 3 h (17%) and movement at 24 h (10%) postwarming. This compares starkly with 0% viability, structure, or movement at all time points in convectively warmed controls (n = 50, p < 0.001, ANOVA). Our nanoparticle-based warming process could be applied to the storage of fish, and with proper modification, can potentially be used for other vertebrate embryos.

Predicting Social Perception from Faces: A Deep Learning Approach (2019)

Warmth and competence represent the fundamental traits in social judgment that determine emotional reactions and behavioral intentions towards social targets. This research investigates whether an algorithm can learn visual representations of social categorization and accurately predict human perceivers' impressions of warmth and competence in face images. In addition, this research unravels which areas of a face are important for the classification of warmth and competence. We use Deep Convolutional Neural Networks to extract features from face images and the Gradient-weighted Class Activation Mapping (Grad CAM) method to understand the importance of face regions for the classification. Given a single face image the trained algorithm could correctly predict warmth impressions with an accuracy of about 90% and competence impressions with an accuracy of about 80%. The findings have implications for the automated processing of faces and the design of artificial characters.
An electrochemical capacitance-voltage technique for the determination of pseudomorphic high electron mobility transistor material parameters (1995)

A novel technique for the extraction of pseudomorphic high electron mobility transistor material parameters has been developed. The technique is based on a reverse engineering technique to iteratively solve for the desired parameters using both simulated and measured electrochemical capacitance-voltage data. Using this technique, the active planar doping efficiency of a pseudomorphic high electron mobility transistor structure was determined for the first time.
Differential gene expression profiles are dependent upon method of peripheral blood collection and RNA isolation (2008)

Here, we demonstrate that peripheral blood RNA isolation methods can critically impact differential expression results, particularly in the clinical setting where fold-change differences are typically small and there is inherent variability within biological cohorts. A modified method based upon the Tempus system was found to provide high yield, good post-hybridization array quality, low variability in expression measures and was shown to produce differential expression results consistent with the predicted immunologic effects of PHA stimulation.
Temperature Fields below Melt-Blowing Dies of Various Geometries (2004)

Temperature fields were measured below two parallel, rectangular air nozzles. These are the types of nozzles that are commonly used in the melt-blowing process to produce fine polymer fibers. Each rectangular nozzle had a large length-to-width ratio, and the nozzles were closely spaced. Three types of nozzles were compared: (1) a die where the jets meet at a 60° angle and the die tip was blunt, (2) a die with a 60° angle and a sharp tip, and (3) a die with a 70° angle and a sharp tip. Correlations were developed to predict the temperature fields below these die types.
BRD4 amplification facilitates an oncogenic gene expression program in high-grade serous ovarian cancer and confers sensitivity to BET inhibitors (2018)

BRD4 is a transcriptional co-activator functioning to recruit regulatory complexes to acetylated chromatin. A subset of High-grade Serous Ovarian Cancer (HGSOC) patients are typified by focal, recurrent BRD4 gene amplifications. Despite previously described cancer dependencies, it is unclear whether BRD4 amplification events are oncogenic in HGSOC. We find that physiologically relevant levels of expression of BRD4 isoforms in non-transformed ovarian cells result in cellular transformation. Transcriptional profiling of BRD4-transformed ovarian cells, and BRD4-amplified HGSOC patient samples revealed shared expression patterns, including enriched MYC, and E2F1 gene signatures. Furthermore, we demonstrate that a novel BET inhibitor, AZD5153, is highly active in BRD4-amplified patient derived xenografts and uncover Neuregulin-1 as a novel BRD4 effector. Experiments involving Neuregulin-1 inhibition and exogenous addition, demonstrate Neuregulin-1 as necessary and sufficient for BRD4-mediated transformation. This study demonstrates the oncogenic potential of BRD4 amplification in cancer and establishes BRD4-amplified HGSOC as a potential patient population that could benefit from BET inhibitors.

Identifying Material and Device Targets for a Flare Gas Recovery System Utilizing Electrochemical Conversion of Methane to Methanol (2016)

Natural gas flaring causes enormous damage to the environment, in addition to the wasted energy. The importance of this problem is highlighted by an initiative by the United Nations to end flaring by 2030. There exists an immediate need for identifying routes for converting flare into usable energy. In this study, we propose a scheme that at the core utilizes an electrochemical cell to convert methane into methanol, an easily transportable fuel. The electrochemical cell uses electricity provided by solar photovoltaics to power the electrochemical cell. We carry out a detailed techno-economic analysis of the entire system and analyze the merits and demerits of the proposed approach as compared with other flare gas recovery systems, gas-to-liquid (GTL), electricity generation with gas turbine, gas compression system, and electricity generation by solid oxide fuel cell (SOFC). The developed model shows that the current state-of-the-art materials available for different system components, proton conductor, and electrocatalysts are inadequate to make the scheme practical. We outline the minimum performance metrics, i.e., input voltage at the cell level of ∼0.5 V that corresponds to an overpotential of ∼1 V and a current density of 0.5 A/cm2 that requires a proton conductor that can conduct from 10–1 to 10–2 S/cm in the temperature range of 100–250 °C, required for the system to become financially competitive. Of note, improvements in the conductivity of proton conductors at intermediate temperatures and identification of active and selective electrocatalysts for the conversion of methane to methanol are the key parameters that determine the overall viability of the proposed scheme. We discuss the environmental impacts of the proposed scheme and provide an outlook on directions required in materials research that could meet the outlined performance metrics.

A Discussion of Early Intervention for Infants with Down Syndrome (1981)

Recently, a physician-colleague brought to our attention an article entitled, "Early Intervention for Infants with Down Syndrome: A Controlled Trial," by Piper and Pless.1 Although it is encouraging to find that these investigators are exploring the parameters of early intervention with handicapped infants, some of their conclusions are of concern and have prompted the formulation of a response. In particular, we would like to discuss this article's findings in relation to (1) existing efficacy data that suggest early intervention with young handicapped children may be effective; and (2) methodologic weaknesses in the research design employed by Piper and Pless. A critical problem currently confronting the field of early intervention is the evaluation of the effectiveness of early programming for handicapped infants and their families. Major impediments to the documentation of program effects include the unsuitability of existing instrumentation for assessing the progress of handicapped infants and the scarcity of feasible evaluation research designs.2,3 To complicate matters further, randomly assigned control or untreated groups for comparison are rarely possible. Ethical concerns surrounding the withholding of services from infants assigned to control groups, coupled with recent state and federal mandates calling for the provision of educatinal services for all handicapped children of school age and permissive programming for the preschool child, are collectively operating to reduce and eventually eliminate available handicapped infants and children who might serve as non-intervention control subjects.4 Despite the design limitations associated with research involving young handicapped children, efficacy findings based on descriptive and quasi-experimental methodology do exist.
Responsiveness of subcutaneous human glioma xenografts to various antitumor agents. (1990)

Responsiveness of seven human glioma xenografts to seven antitumor agents was investigated by an sc-iv system and the efficacies of these agents against human glioma were evaluated in terms of response rate. When their maximum tolerated doses were used, experimental response rates of nimustine (ACNU), vincristine (VCR), adriamycin (ADR) and vinblastine (VLB) were as high as 86-100%, while that of mitomycin (MMC) was 57%, and those of 5-fluorouracil (5-FU) and methotrexate (MTX) were 0%. On the other hand, when the doses pharmacokinetically equivalent to their clinical doses were employed, the response rate of ADR was the highest, followed by VCR and ACNU in this order. These results suggest that gliomas are significantly responsive to various antitumor agents in this sc-iv system.
British Teacher Unions and the Blair Government Anatomy of an Abusive Relationship (2008)

As a young teacher [in South Africa] in the 1980s, my dream was to build a nonracial teacher union. At that time, teachers had no right to even join a union—they had no labor rights at all. Teachers were divided along ethnic, racial, and even regional lines. These were the times at the climax of apartheid, some of it under a state of emergency where teachers were expelled from the profession for joining a union. It was worse for those who were seen to be leaders of the movement, and I lost my job. After that I joined the university and we used the university as our base for the trade union—I ended up being the general secretary of the National Education Union of South Africa, which was one of the founding organizations of SADTU.

A new form of the extended Kalman filter for parameter estimation in linear systems with correlated noise (1980)

A well-known method for estimation of parameters in linear systems with correlated noise is the extended Kalman filter where the unknown parameters are estimated as a part of an enlarged state vector. To avoid the computational burden in determining the state estimates when only the parameter estimates are required, a new simple form of the extended Kalman filter, where the state consists only of the parameters to be estimated, is proposed. The algorithm is based on the inclusion of the computed residuals in the observation matrix of a state representation of the system, an idea first introduced in the so-called extended least-squares or Panuska's method. Convergence properties of the proposed algorithm are studied, and the algorithm is shown to perform a gradient-based minimization of the maximum likelihood loss function. Some special cases of the algorithm are also discussed, and an extension to an estimator for randomly varying parameters is outlined.
Guidelines for Data Collection Techniques and Methods for Roadside Station Origin-Destination Studies (2005)

Origin-Destination studies are often used in transportation planning to determine the travel patterns (origin-destination matrix) of vehicles and goods in a particular area. Given these travel patterns, the impacts of alternative solutions to current and future transportation problems can be evaluated. Therefore, it is important that the travel patterns be accurately measured. However, it is not always clear what data collection method should be used to obtain the type of data needed, while maximizing quality and minimizing the time and cost. The objective of this research is to review both conventional and experimental techniques for roadside station OD studies, and make general recommendations for the best OD study technique and data collection method, given the roadway characteristics and traffic conditions.
