Neural Rendering and Reenactment of Human Actor Videos (2019)

We propose a method for generating video-realistic animations of real humans under user control. In contrast to conventional human character rendering, we do not require the availability of a production-quality photo-realistic three-dimensional (3D) model of the human but instead rely on a video sequence in conjunction with a (medium-quality) controllable 3D template model of the person. With that, our approach significantly reduces production cost compared to conventional rendering approaches based on production-quality 3D models and can also be used to realistically edit existing videos. Technically, this is achieved by training a neural network that translates simple synthetic images of a human character into realistic imagery. For training our networks, we first track the 3D motion of the person in the video using the template model and subsequently generate a synthetically rendered version of the video. These images are then used to train a conditional generative adversarial network that translates synthetic images of the 3D model into realistic imagery of the human. We evaluate our method for the reenactment of another person that is tracked to obtain the motion data, and show video results generated from artist-designed skeleton motion. Our results outperform the state of the art in learning-based human image synthesis.

Antiapoptotic but Not Antiviral Function of Human <i>bcl-2</i> Assists Establishment of Japanese Encephalitis Virus Persistence in Cultured Cells (1998)

Upon infection of Japanese encephalitis virus (JEV), baby hamster kidney (BHK-21) and Chinese hamster ovary (CHO) cells were killed by a mechanism involved in apoptosis. While readily established in a variety of cell lines, JEV persistence has never been successfully instituted in BHK-21 and CHO cells. Since stable expression of human bcl-2 in BHK-21 cells has been shown to delay JEV-induced apoptosis, in this study we investigated whether JEV persistence could be established in such cells. When constitutively expressing bcl-2, but not its closest homolog, bcl-XL, following a primary lytic infection, approximately 5 to 10% of BHK-21 and CHO cells became persistently JEV infected during a long-term culture. From the persistent bulks, several independent clones were selected and expanded to form stable cell lines that continuously produced infectious virus without marked cytopathic effects (CPE). Among these stable cell lines, the truncated nonstructural protein 1 (NS1) was also detected and was indistinguishable from the NS1 truncations previously observed in JEV-persistent murine neuroblastoma N18 cells. However, the stable expression of NS1 alone, regardless of whether it was truncated or full length, failed to render the engineered cells persistently infected by JEV, implying that aberrant NS1 proteins were likely a consequence of, rather than a cause for, the viral persistence. Enforced bcl-2 expression, which did not affect virus replication and spread during the early phase of cytolytic infection, appeared to attain JEV persistence by restriction of virus-induced CPE. Our results suggest that it is the antiapoptotic, rather than the antiviral, effect of cellular bcl-2 which plays a role in the establishment of JEV persistence.
Filling Single-Wall Carbon Nanotubes with d- and f-Metal Chloride and Metal Nanowires (2003)

Nanowires of magnetic metals (Fe, Co, Ho, Gd) have been synthesized inside the hollow interiors of single-wall carbon nanotubes (SWNTs) by filling SWNTs with precursor metal chlorides and subsequent reduction. SWNTs have been filled by either the melt-phase sealed-tube reaction or a solution-phase method. Among the metal chlorides investigated in this study, HoCl3 and GdCl3 filled the SWNTs to a significantly higher extent. The nanowires have been imaged by transmission electron microscopy (TEM), high-resolution transmission electron microscopy, and scanning transmission electron microscopy (STEM). X-ray energy dispersive spectroscopy carried out in conjunction with TEM and STEM confirmed the presence of metal chloride and metal nanowires.
Self Correction Algorithm of Amplitude Phase Error Based on the Subspace (2013)

Aiming at the array amplitude phase errors perturbation problem widespread in practical application ,a self-calibration algorithm which combines with subspace DOA estimation algorithm for amplitude phase error is presented in this paper. Firstly, the amplitude phase error is preliminary calibrated using the structural characteristics of equality linear array covariance matrix. Then the more accurate estimation is gained through the iterative method. Self-calibration method doesn't need any initial parameter and easy to realize. The simulation shows that the algorithm has good effect on error calibration and can accurately estimate the azimuth and the value of the amplitude phase error.
IL-11 system participates in pulmonary artery remodeling and hypertension in pulmonary fibrosis (2022)

Abstract Background Pulmonary hypertension (PH) associated to idiopathic pulmonary fibrosis (IPF) portends a poor prognosis. IL-11 has been implicated in fibrotic diseases, but their role on pulmonary vessels is unknown. Here we analyzed the contribution of IL-11 to PH in patients with IPF and the potential mechanism implicated. Methods Pulmonary arteries, lung tissue and serum of control subjects (n = 20), IPF (n = 20) and PH associated to IPF (n = 20) were used to study the expression and localization of IL-11 and IL-11Rα. Two models of IL-11 and bleomycin-induced lung fibrosis associated to PH were used in Tie2-GFP transgenic mice to evaluate the contribution of IL-11 and endothelial cells to pulmonary artery remodeling. The effect of IL-11 and soluble IL-11Rα on human pulmonary artery endothelial cells and smooth muscle cell transformations and proliferation were analyzed. Results IL-11 and IL-11Rα were over-expressed in pulmonary arteries and serum of patients with PH associated to IPF vs IPF patients without PH. Recombinant mice (rm)IL-11 induced lung fibrosis and PH in Tie2-GFP mice, activating in vivo EnMT as a contributor of pulmonary artery remodeling and lung fibrosis. Transient transfection of siRNA-IL-11 reduced lung fibrosis and PH in Tie2-GFP bleomycin model. Human (h)rIL-11 and soluble hrIL-11Rα induced endothelial to mesenchymal transition (EnMT) and pulmonary artery smooth muscle cell to myofibroblast-like transformation, cell proliferation and senescence in vitro . Conclusions IL-11 and IL-11Rα are overexpressed in pulmonary arteries of PH associated to IPF patients, and contributes to pulmonary artery remodeling and PH.
Deep-Red and Near-Infrared Xanthene Dyes for Rapid Live Cell Imaging (2016)

In this work, two xanthene dyes (H-hNR and TF-hNR) have been synthesized by a convenient and efficient method. These two dyes exhibited deep-red and near-infrared emissions, high fluorescence quantum yields, and good photostability. Their structure-optical properties were investigated by X-ray crystal structure analysis and density functional theory calculations. Live cell imaging data revealed that H-hNR and TF-hNR could rapidly stain both A549 and HeLa cells with low concentrations. The excellent photophysical and imaging properties render them as promising candidates for use in live cell imaging.
Wideband Vector Antenna for Dual-Polarized and Three-Dimensional Direction-Finding Applications (2019)

A wideband and reconfigurable radiation pattern vector antenna is proposed for dual-polarized and three-dimensional direction-finding applications. Compared with the state of the art, this antenna achieves the accurate estimation of the direction of arrival of an incoming vertically or horizontally polarized electromagnetic field over a wider bandwidth (7:1). Measurement results are in good agreement with the simulated results obtained from full-wave electromagnetic simulations.
Incremental recognition of pedestrians from image sequences (2002)

An approach that uses a volume model consisting of cylinders for model-based recognition of pedestrians in real-world images is presented. The human body is represented by a volume model, and medical motion data are used for simulating the movement of walking. This knowledge is exploited to determine the 3-D position, as well as the posture of an observed person. By applying a Kalman filter, the model parameters in consecutive images are incrementally estimated. The approach is tested on real image data.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High Performance Al<sub>0.10</sub>Ga<sub>0.90</sub>N Channel HEMTs (2018)

This letter reports the large maximum drain current AlGaN channel high-electron-mobility transistors (HEMTs) of 849 mA/mm with graded buffers and constant channel layer. The large drain current and the transconductance benefit from the high electronic mobility of 807 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /V · s and high saturated velocity. Furthermore, the device also shows a low off-state drain current of ~1 nA/mm and an ultrahigh ION/IOFF up to ~10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">9</sup> . To the best of the authors' knowledge, the electronic mobility, the maximum drain current, and ION/IOFF ratio all are the largest reported results ever achieved on the AlGaN channel HEMTs. These results not only drastically reduce the performance gaps between the AlGaN channel HEMT and the GaN channel HEMT in the maximum drain current, the maximum transconductance, and the electronic mobility, but also demonstrate better performances in the gate leakage current, the off-state drain current, ION/IOFF ratio, and the breakdown voltage.

Identifying Strategies to Increase Cervical Cancer Screening Rates in a Federally Qualified Health Center (2020)

INTRODUCTION AND OBJECTIVES: Interval colorectal cancer (ICC) is defined as Though cervical cancer-related deaths have significantly decreased since the implementation of cervical cancer screening (CCS) via the Papanicolaou (Pap) smear, it remains a leading cause of death in low-income and racial/ethnic minority women, possibly attributed to access to screening. Federally Qualified Health Centers (FQHC) typically serve low-income women and, on average, have a 53% CCS rate compared to the 80+% national screening rate.1 Cervical cancer is also diagnosed at more advanced stages at FQHCs. Factors that affect screening rates include electronic medical record (EMR) support, staff ratios, and the primary care physician’s availability to screen. Our FQHC family medicine residency aimed to increase CCS to greater than 60% with multiple quality improvement cycles over two years. METHODS: Quality improvement (QI) projects on CCS were executed via “plan-do-study-act” (PDSA), 4 month cycles from June 2018 to September 2020, focusing on utilizing EMR support, improving staff ratios, and increasing physician availability to screen. Cycle #1 used the EMR for patient education via a templated after-visit summary (AVS). Cycles #2 and 3 encouraged staff to review the patients’ chart for documented CCS and encourage same-day CCS if applicable. Cycle #4 aimed to improve clinician and staff communication prior to the start of each clinic to prepare for CCS. Cycle #5, the current cycle, will aim to offer CCS to any eligible patient if none are documented in the EMR, have attending physicians encourage CCS if patient declines with the resident physician, and have a female physician, resident and attendings, available at all times to complete CCS if the patient prefers. A pre- and post-test questionnaire and CCS rates were reviewed with each cycle. RESULTS: Cycle #1 had a slight increase in screening rate from 57.9% to 59.5%. Cycle #2 and #3 saw decreases in CCS to 57 and 49%, respectively. Cycle #4, however, saw an increase in CCS from 49 to 55% by increasing communication between physicians and staff via huddling before each clinic. The current cycle’s results are not yet available. CONCLUSIONS: These findings suggest that the strategies used to increase CCS likely requires a multifaceted approach that includes more patient education, interdisciplinary collaboration, better utilization of the EHR, and continuation of mandatory huddles. Future interventions should continue to focus on patient education, improving CCS health literacy, with the goal of improving health disparities in communities similar to that represented by an FQHC.
Solution-Processed Hybrid Graphene Flake/2H-MoS<sub>2</sub> Quantum Dot Heterostructures for Efficient Electrochemical Hydrogen Evolution (2017)

We designed solution-processed, flexible hybrid graphene flake/2H-MoS2 quantum dot (QD) heterostructures, showing enhanced electrocatalytic activity for the hydrogen evolution reaction (HER) with respect to their native individual components. The 2H-MoS2 QDs are produced through a scalable, environmentally friendly, one-step solvothermal approach from two-dimensional (2D) 2H-MoS2 flakes obtained by liquid phase exfoliation (LPE) of their bulk counterpart in 2-Propanol. This QDs synthesis avoids the use of high boiling point and/or toxic solvents. Graphene flakes are produced by LPE of graphite in N-Methyl-2-pyrrolidone. The electrochemical properties of 2H-MoS2 QDs and their HER-favorable chemical and electronic coupling with graphene enable to reach a current density of 10 mA/cm^2 at an overpotential of 136 mV, surpassing the performances of graphene flake/2H-MoS2 (1T-MoS2) flake heterostructures. Our approach provides a shortcut, viable and cost-effective method for enhancing the 2D materials electrocatalytic properties.
New Trends and Future Opportunities in the Enzymatic Formation of C−C, C−N, and C−O bonds (2021)

Organic chemistry provides society with fundamental products we use daily. Concerns about the impact that the chemical industry has over the environment is propelling major changes in the way we manufacture chemicals. Biocatalysis offers an alternative to other synthetic approaches as it employs enzymes, Nature's catalysts, to carry out chemical transformations. Enzymes are biodegradable, come from renewable sources, operate under mild reaction conditions, and display high selectivities in the processes they catalyse. As a highly multidisciplinary field, biocatalysis benefits from advances in different areas, and developments in the fields of molecular biology, bioinformatics, and chemical engineering have accelerated the extension of the range of available transformations (E. L. Bell et al., Nat. Rev. Meth. Prim. 2021, 1, 1-21). Recently, we surveyed advances in the expansion of the scope of biocatalysis via enzyme discovery and protein engineering (J. R. Marshall et al., Tetrahedron 2021, 82, 131926). Herein, we focus on novel enzymes currently available to the broad synthetic community for the construction of new C-C, C-N and C-O bonds, with the purpose of providing the non-specialist with new and alternative tools for chiral and sustainable chemical synthesis.
Getting to 2020: The Canadian forces and future force structure and investment considerations (2002)

The author analyses the combat capability of the Canadian Forces and argues that the most expedient use of limited investment dollars provided by the Department of National Defence would be to overcome the psychological anathema of specialization. Using the United States as an exemplar of the kind of force structure that Canada and others could pursue, he discusses the types of investment choices that are available to Canada within the budgetary constraints imposed. He argues not for duplication of the American model, but for transformation, employing cost‐effective RMA technologies, and ensuring some degree of balanced combat force among the Army, Navy, and Air Force. But RMA technologies will also demand new force structures, of which the idea of ‘joint‐ness’ among the services is just the tip of the iceberg. Decisions made in the next several years will dictate the nature of the CF in 2020; waiting for the RMA to unfold will be too late.
Characterization of power distribution lines for high-speed data transmission (2002)

This paper presents techniques for characterization of power lines in Singapore power distribution network and methodologies to extract necessary information from the measured data in 1 MHz to 10 MHz frequency range. Measurements are made on the noises in actual residential power lines, which are generated from some typical electrical apparatuses used in an ordinary home. The equipment and locations used to obtain our measurements are described. The results of impulse noise measurements in typical residential power lines are presented. Statistical analyses of the measurements are presented in the form of amplitude probability distributions, pulse duration distributions, and interarrival time distributions. From the results obtained so far, it is observed that the noise and signal attenuation of power distribution lines vary with frequency, time and location. These are caused by the rather dynamic nature of power lines and their connected loads that are changing all the time.
Murine sepsis phenotypes and differential treatment effects in a randomized trial of prompt antibiotics and fluids (2019)

We identified two sepsis phenotypes in a murine cecal ligation and puncture model, one of which is characterized by faster deterioration and more severe inflammation. Response to treatment in a randomized trial of immediate versus delayed antibiotics and fluids differed on the basis of phenotype.
On-chip voltage-droop prediction using support-vector machines (2014)

Voltage droop is a major reliability concern in nano-scale VLSI designs. Undesirable voltage droop occurs when logic gates in the circuit draw high switching current from the on-chip power supply network, and this problem is exacerbated at high clock frequencies and smaller technology nodes. A consequence of voltage droop is an increase in path delays and the occurrence of intermittent faults during circuit operation. The addition of conservative timing margins, a.k.a. guardbands, is a common practice to tackle the problem of voltage droop. However, such static and pessimistic guardbands, which are calculated at design time based on worst-case conditions, lead to significant performance loss. Dynamic frequency scaling (DVF) is an alternative approach that enables the dynamic adjustment of clock frequency based on the actual voltage droop seen during runtime. For DVF to be effective, accurate and real-time prediction of voltage droop is essential. We propose a support-vector machine (SVM)-based regression method to predict voltage droop at runtime. Several benchmarks from ITC99 and IWLS'05 highlight the effectiveness of the proposed method in terms of delay-prediction accuracy. Since real-time droop prediction requires hardware implementation of the predictor, we present synthesis results to demonstrate that the hardware overhead for the SVM predictor is negligible for large circuits.
Counterions in Polymeric Amino Acid Based Surfactants:  Effect on Physical Properties and Enantioselectivity (2003)

The influence of alkali metal counterions on micellar properties and chiral recognition of poly-N-undecenoyl-l-leucinate (poly-L-UL) surfactant was investigated by use of surface tensiometry, fluorescence spectroscopy, pulsed field gradient NMR (PFG-NMR), and micellar electrokinetic chromatography (MEKC). The larger counterions (Rb+ and Cs+) showed a dramatic increase in the critical micelle concentration. In addition, fluorescence and PFG-NMR experiments showed a general increase in micellar polarity and diffusion coefficients, respectively, with increasing counterion size. Fluorescence and PFG-NMR data were interpreted in terms of different micellar aggregates that form in the presence of the different counterions: Li+, Na+, K+, Rb+, and Cs+. Significant effects were observed in the presence of Rb+ and Cs+. A group of six chiral analytes were used to test the chiral selectivity (α), chiral resolutions (Rs), and retention factors (k‘) using the alkali metal counterions of poly-L-UL micelles in MEKC. In general the measured,α, Rs, and k‘ values depended on the counterions. For example, benzoin derivatives (±)-benzoin and (±)-benzoin methyl ether as well as binaphthyl derivatives (±)-1, 1‘-binaphthyl-2, 2‘-dihydrogen phosphate, (±)-1, 1‘-binaphthyl-2, 2‘-diamine, and (±)-1,1‘-bi-2-naphthol showed the highest Rs and α with poly-L-CsUL. In contrast, poly-L-KUL showed better Rs and α values for (±)-aminoglutethimide (AMGL). In poly-L-CsUL, high capacity factors (k‘) were exhibited except for (±)-AMGL analyte. The highest k‘ values for the latter analyte were observed in the presence of poly-L-KUL. The MEKC data collected after removal of the counterions followed by reconstitution of the sodium salts of poly-L-UL suggest that not only is the counterion size essential during polymerization of L-UL surfactant but also the presence of counterions in the running buffer is necessary to influence chiral resolution and selectivity.
Plasma-Assisted MOCVD Growth of GaAs/GaN/GaAs Thin-Layer Structures by N-As Replacement Using N-Radicals (1994)

GaAs/GaN/GaAs thin-layer structures were grown by plasma-assisted low-pressure metalorganic chemical vapor deposition. GaN layers were formed by exposing the surfaces of GaAs epitaxial layers to nitrogen-radical fluxes. When the nitrogen amount exceeded that in one-monolayer-thick GaN, the GaN/GaAs interfaces deteriorated drastically. Low-temperature photoluminescence from the structures suggests that the two-dimensional growth of GaN is limited to one-monolayer thick and that the excess nitrogen atoms form GaN clusters in the underlying layers. The one-monolayer-thick GaN embedded in GaAs shows intense photoluminescence, whereas the GaN cluster is non-radiative, probably because of the defects caused by the large lattice-mismatch between GaN and GaAs.
