PVP: Personalized Video Prior for Editable Dynamic Portraits using StyleGAN (2023)

Portrait synthesis creates realistic digital avatars which enable users to interact with others in a compelling way. Recent advances in StyleGAN and its extensions have shown promising results in synthesizing photorealistic and accurate reconstruction of human faces. However, previous methods often focus on frontal face synthesis and most methods are not able to handle large head rotations due to the training data distribution of StyleGAN. In this work, our goal is to take as input a monocular video of a face, and create an editable dynamic portrait able to handle extreme head poses. The user can create novel viewpoints, edit the appearance, and animate the face. Our method utilizes pivotal tuning inversion (PTI) to learn a personalized video prior from a monocular video sequence. Then we can input pose and expression coefficients to MLPs and manipulate the latent vectors to synthesize different viewpoints and expressions of the subject. We also propose novel loss functions to further disentangle pose and expression in the latent space. Our algorithm shows much better performance over previous approaches on monocular video datasets, and it is also capable of running in real-time at 54 FPS on an RTX 3080.
Reduction of house dust mites and mite allergens: effects of spraying carpets and blankets with Allersearch DMS, an acaricide combined with an allergen reducing agent (1989)

Two studies were made to determine the acaricidal and allergen reducing properties of Allersearch DMS solution. In Study 1, samples of dust and carpet containing living mites were treated, in vitro, with DMS solution. No living mites were found in dust after 3-4 min or in carpets 50 min after treatment. In Study 2, mite counts and allergen estimation made on bed blankets before and after spraying with DMS solution showed a marked reduction in mite numbers (95%) and allergenicity (100-fold). Mite numbers and allergenicity stayed at this low level for 6 weeks. At 16 weeks both mites and allergens showed a slight increase, but were still significantly (P less than 0.001) below pretreatment levels.
A minimum scale architecture for rover-based sample acquisition and caching (2013)

The Minimum Scale Sample Acquisition and Caching (MinSAC) architecture has been developed to enable rover-based sample acquisition and caching while minimizing the system mass. The MinSAC architecture is a version of the previously developed Integrated Mars Sample Acquisition and Handling (IMSAH) architecture. The MinSAC implementation utilizes the sampling manipulator both for sampling and sample tube transfer. This significantly reduces the number of actuators in the sample acquisition and caching subsystem. A core sample is acquired directly into its sample tube in the coring bit. The bit is transferred and released on the rover. A tube gripper on the robotic arm turret pulls the filled sample tube out of the back of the coring bit and the tube is sealed. The sample tube is then placed in the return sample canister. A new tube is placed in the bit for acquisition of another sample.
Blahut-Arimoto algorithm and code design for action-dependent source coding problems (2013)

The source coding problem with action-dependent side information at the decoder has recently been introduced to model data acquisition in resource-constrained systems. In this paper, an efficient Blahut-Arimoto-type algorithm for the numerical computation of the rate-distortion-cost function for this problem is proposed. Moreover, a simplified two-stage code structure based on multiplexing is put forth, whereby the first stage encodes the actions and the second stage is composed of an array of classical Wyner-Ziv codes, one for each action. Leveraging this structure, specific coding/decoding strategies are designed based on LDGM codes and message passing. Through numerical examples, the proposed code design is shown to achieve performance close to the rate-distortion-cost function.
Disproportionation Mechanism of Alkylbenzenes lnduced by Aluminum Chloride-Hydrogen Chloride (1974)

アルキルベンゼン-塩化アルミニウム系錯体層の構造と不均化反応との関係を調べるために,エチル-およびイソプロピル-ベンゼンを用いて錯体層をつくり,その上層の炭化水素層を新しいアルキルベンゼンと交換して反応させることをくり返し,各回ごとに得られる上層の不均化生成物をVPCで分析した。錯体層は,アルキルベンゼンがH+AlCl4-によってプトン化され, 2+LAlCl4-のような錯体〔1〕をつくり,これに過剰に存在するアルキルベンゼンの一部が溶解したものと考えられる。〔1〕はやわらかい酸とかたい塩基(AlCl4-)との塩であるから,HClが存在したり,温度が高くなると不安定になり,HSAB則から,R+は錯体層中に存在するやわらか塩基である他のアルキルベンゼン環を攻撃してかたい酸であるH+を放出し,不均化することが考えられた。
Lorazepam treatment of experimental status epilepticus in the rat (1990)

We studied the efficacy, pharmacokinetics, and brain entry of lorazepam in the treatment of status epilepticus (SE) using a rat model of secondarily generalized convulsive SE. Lorazepam entered the bloodstream rapidly following intraperitoneal injection. Brain concentrations peaked 10 minutes after peak serum levels were achieved. Lorazepam remained in brain longer than in serum, leading to increasing brain: serum ratios over time once peak serum levels had been reached. Free lorazepam was 9.1% of the total concentration in serum, a fraction similar to that which has been reported for humans. The median effective dose for control of generalized tonic-clonic seizures in this model was 0.94 mg/kg, which would produce a serum concentration of 196 ng/ml. Rats in SE had higher serum lorazepam concentrations than controls given the same doses, but lower brain: serum ratios, perhaps due to lactic acidosis during SE. Our data confirmed clinical reports of lorazepam's effectiveness as a treatment for SE and suggest that a target serum concentration of 200 ng/ml should be effective in most cases and provide seizure protection for 24 hours following treatment.
Evolution of CdS/CdTe device performance during Cu diffusion (2005)

Cu diffusion from a ZnTe:Cu/Ti back contact onto CdS/CdTe thin-film solar cells is studied. We find if Cu diffusion is insufficient, the entire CdTe layer is depleted. However, if Cu diffusion is excessive, the depletion width can become too narrow to provide optimum current collection. This analysis suggests that most contact processes used for CdS/CdTe devices are optimized (often unknowingly) to result in a depletion width that extends just far enough into the CdTe to yield the highest possible field in the region where light absorption occurs. Analysis of the samples with very high Cu concentration also suggests that Cu doping of CdS may affect carrier collection from the CdS.
Skin disease identification from dermoscopy images using deep convolutional neural network (2018)

In this paper, a deep neural network based ensemble method is experimented for automatic identification of skin disease from dermoscopic images. The developed algorithm is applied on the task3 of the ISIC 2018 challenge dataset (Skin Lesion Analysis Towards Melanoma Detection).
Characterization of an unusual tRNA-like sequence found inserted in a Neurospora retroplasmid (2000)

We characterized an unusual tRNA-like sequence that had been found inserted in suppressive variants of the mitochondrial retroplasmid of Neurospora intermedia strain Varkud. We previously identified two forms of the tRNA-like sequence, one of 64 nt (TRL-64)and the other of 78 nt (TRL-78) containing a 14-nt internal insertion in the anticodon stem at a position expected for a nuclear tRNA intron. Here, we show that TRL-78 is encoded in Varkud mitochondrial (mt)DNA within a 7 kb sequence that is not present in Neurospora crassa wild-type 74A mtDNA. This 7-kb insertion also contains a perfectly duplicated tRNA(Trp)gene, segments of several mitochondrial plasmids and numerous GC-rich pallindromic sequences that are repeated elsewhere in the mtDNA. The mtDNA-encoded copy of TRL-78 is transcribed and apparently undergoes 5'- and 3'-end processing and 3' nucleotide addition by tRNA nucleotidyl transferase to yield a discrete tRNA-sized molecule. However, the 14 nt intron-like sequence in TRL-78, which is missing in the TRL-64 form, is not spliced detectably in vivo or in vitro. Our results show that TRL-78 is an unusual tRNA-like species that could be incorporated into suppressive retroplasmids by the same reverse transcription mechanism used to incorporate mt tRNAs. The tRNA-like sequence may have been derived from an intron-containing nuclear tRNA gene or it may serve some function, like tmRNA. Our results suggest that mtRNAs or tRNA-like species may be integrated into mtDNA via reverse transcription, analogous to SINE elements in animal cells.
Upconverting Nanoparticles (2011)

Upconversion (UC) refers to nonlinear optical processes in which the sequential absorption of two or more photons leads to the emission of light at shorter wavelength than the excitation wavelength (anti-Stokes type emission). In contrast to other emission processes based on multiphoton absorption, upconversion can be efficiently excited even at low excitation densities. The most efficient UC mechanisms are present in solid-state materials doped with rare-earth ions. The development of nanocrystal research has evoked increasing interest in the development of synthesis routes which allow the synthesis of highly efficient, small UC particles with narrow size distribution able to form transparent solutions in a wide range of solvents. Meanwhile, high-quality UC nanocrystals can be routinely synthesized and their solubility, particle size, crystallographic phase, optical properties and shape can be controlled. In recent years, these particles have been discussed as promising alternatives to organic fluorophosphors and quantum dots in the field of medical imaging.
S-Farnesyl-Thiopropionic Acid Triazoles as Potent Inhibitors of Isoprenylcysteine Carboxyl Methyltransferase (2011)

We report the design and synthesis of novel FTPA-triazole compounds as potent inhibitors of isoprenylcysteine carboxyl methyltransferase (Icmt), through a focus on thioether and isoprenoid mimetics. These mimetics were coupled utilizing a copper-assisted cycloaddition to assemble the potential inhibitors. Using the resulting triazole from the coupling as an isoprenyl mimetic resulted in the biphenyl substituted FTPA triazole 10n. This lipid-modified analog is a potent inhibitor of Icmt (IC(50) = 0.8 ± 0.1 μM; calculated K(i) = 0.4 μM).
Growth of Pathogenic Leptospira in Chemically Defined Media (1967)

A protein-free chemically defined medium for cultivation of pathogenic Leptospira was developed. The medium permitted continued serial subculturing of 9 serogroups (52 strains) of the 12 serogroups (61 strains) tested. Growth was initiated from small inocula, and the growth rate and maximal cell yields were similar to those on serum-containing media. The nutritional requirements of serogroups L. canicola, L. pomona, and L. grippotyphosa were studied in a basal medium composed of inorganic salts, a fatty acid, vitamin B(12), and thiamine. All strains tested utilized ammonium chloride as the sole nitrogen source. A fatty acid, vitamin B(12), and ferrous ions were essential. Growth was stimulated by thiamine, potassium, and calcium ions.
Network synchronization for distributed MANET (2008)

Mobile ad-hoc networks (MANET) are often characterized with rapidly changing topologies, presenting a constant challenge for time synchronization. This challenge holds especially true in tactical edge ground military networks, where topological instabilities are enhanced by hostile transmission environments. In the absence of GPS, time synchronization within the context of a tactical environment requires resilience and ease of deployment. Hardware requirements must be carefully controlled, while relying on distributed coordination techniques to avoid single points of failure. Current tactical ground networks are often deployed without high accuracy oscillators, but still require time synchronization on the order of 1us. Our work demonstrates a distributed synchronization approach with a resource efficient solution that handles these requirements. We introduce cross-layer ad-hoc network synchronization (CLANS), a low overhead time synchronization protocol designed for MANETs and enables coarse synchronization without relying on GPS data. CLANS leverages routing information, channel access schemes, and distributed scheduling protocols that typically exist in a MANET. This provides a resilient, distributed time synchronization solution with relaxed hardware requirements. Simulation results show that CLANS can achieve network synchronization within 1 us in lossy multi-hop networks with the presence of packet loss and measurement noise.
Relativistic motion in gamma-ray bursts (1991)

Three fundamental problems affect models of gamma-ray bursts, i.e., the energy source, the ability of high-energy photons to escape the radiation region, and the comparative weakness of X-ray emission. It is indicated that relativistic bulk motion of the gamma-ray-emitting plasma generically provides a solution to all three of these problems. Results show that, if the plasma that produces gamma-ray bursts has a bulk relativistic velocity with Lorentz factor gamma of about 10, several of the most troubling problems having to do with gamma-ray bursts are solved.

A Bond Graph Model for the Sample Extraction / Injection System of a Micro-Sized Gas Chromatographic Instrument (1996)

Abstract A bond graph model of the sample extraction/injection system of a prototype portable gas chromatographic instrument has been developed. In addition to performing the same functions as current portable GCs, the new generation of GC instruments is designed to perform extraction of analytes from liquid and solid samples. A novel sample extraction/injection module is essential to the improved performance of the portable instrument, which will include microfabricated components such as inlets, interface chips, fluid channels, control valves, optimal heater/sensor combinations, and multi-port connectors. Predicting the performance of the system in this operating regime requires the modeling and analysis of system behavior in two interacting energy domains, fluid and thermal. Simulation results using the bond graph model closely match available experimental data, with differences typically less than 10%. This demonstrates that fluid dynamic theory for macro-scale systems, and the bond graph method based on it, can be readily applied to micro-scale systems with these dimensions.
Exposure of pipe insulation to high temperatures from domestic pumped storage (split) solar water heating systems in Australia and New Zealand (2010)

Pipe insulation between the collector and storage tank on pumped storage (commonly called split), solar water heaters can be subject to high temperatures, with a maximum equal to the collector stagnation temperature. The frequency of occurrence of these temperatures is dependent on many factors including climate, hot water demand, system size and efficiency. This paper outlines the findings of a computer modelling study to quantify the frequency of occurrence of pipe temperatures of 80 degrees Celsius or greater at the outlet of the collectors for these systems. This study will help insulation suppliers determine the suitability of their materials for this application. The TRNSYS program was used to model the performance of a common size of domestic split solar system, using both flat plate and evacuated tube, selective surface collectors. Each system was modelled at a representative city in each of the 6 climate zones for Australia and New Zealand, according to AS/NZS4234 - Heat Water Systems - Calculation of energy consumption, and the ORER RECs calculation method. TRNSYS was used to predict the frequency of occurrence of the temperatures that the pipe insulation would be exposed to over an average year, for hot water consumption patterns specified in AS/NZS4234, and for worst case conditions in each of the climate zones. The results show; * For selectively surfaced, flat plate collectors in the hottest location (Alice Sprints) with a medium size hot water demand according to AS/NZS2434, the annual frequency of occurrence of temperatures at and above 80 degrees Celsius was 33 hours. The frequency of temperatures at and above 140 degrees Celsius was insignificant. * For evacuated tube collectors in the hottest location (Alice Springs), the annual frequency of temperatures at and above 80 degrees Celsius was 50 hours. Temperatures at and above 140 degrees Celsius were significant and were estimated to occur for more than 21 hours per year in this climate zone. Even in Melbourne, temperatures at and above 80 degrees can occur for 12 hours per year and at and above 140 degrees for 5 hours per year. * The worst case identified was for evacuated tube collectors in Alice Springs, with mostly afternoon loads in January. Under these conditions, the frequency of temperatures at and above 80 degrees Celsius was 10 hours for this month only. Temperatures at and above 140 degrees Celsius were predicted to occur for 5 hours in January.
Electrochemical Study of La0.31Sr0.58Ti0.97Ni0.03O3-δ Thin Film and Pt-10Sc1CeSZ Electrodes (2023)

In this work thin film SOFC anode MIEC La 0.31 Sr 0.58 Ti 0.97 Ni 0.03 O 3-δ (LSTN) electrodes with embedded 200 nm thick Pt current collectrors (CC-s) and electrodes without CC-s deposited on 10Sc1CeSZ electrolyte were studied in 650 °C in 98.5% H 2 and 1.5 % H 2 O at ambient pressure. Additionally Pt-10Sc1CeSZ electrodes were characterized to determine CC-s own electrochemical activity. It was found that the embedded Pt was the most active part of an LSTN electrode with Pt CC despite the common presumption that covering Pt current collector with dense MIEC layer makes it inactive. Diffusion of H 2 through both LSTN and Pt layers and reaction on the Pt-10Sc1CeSZ interface is proposed. Formation of bubbles under embedded Pt in hydrogen atmosphere was seen and is explained with formation of trapped H 2 O.
Comparison of the hybrid capture tube test and PCR for detection of human papillomavirus DNA in cervical specimens (1997)

The strong association of human papillomavirus (HPV) and cervical cancer makes it important to study HPV detection methods that may play a role in cervical cancer screening. We compared two DNA methods that are commonly used for HPV research in the United States: the MY09/MY11 L1 consensus primer PCR-based test and the first-generation Hybrid Capture tube method (HCT). Laboratory assays by each method were performed with 596 cervicovaginal specimens collected from participants in a large cohort study conducted in Portland, Oreg. Included were 499 specimens from women whose cytology was normal and 97 specimens from women with squamous intraepithelial lesions (SILs). The overall HPV DNA positivity for known types was 22.5% by PCR compared to 13.6% by HCT. When the analysis was restricted to the 14 HPV types detectable by both methods, the sensitivity of HCT, with PCR used as the standard for HPV status, was higher for specimens from women with concurrent SILs (81.0%) than for specimens from women with normal cytology (46.7%). Among specimens testing positive by both methods, 97.2% of the time the two methods agreed on whether specimens were positive for cancer-associated HPV types. Both of these HPV test methods provide information that supplements the information provided by the Pap smear. The PCR method has higher analytic sensitivity than HCT in detecting HPV, but HCT may be helpful in identifying women with concurrent SILs.
Droplet Heat Transfer on Micropost Arrays With Hydrophobic and Hydrophilic Characteristics (2018)

Heat transfer analysis for a water droplet on micropost arrays is carried out while mimicking the environmental conditions. Since the micropost arrays spacing size alters the state of the hydrophilicity of the surface, the size of the micropost arrays spacing is varied and the resulting heat transfer characteristics are analyzed. Spreading rate of water droplet on the micropost arrays is considered and the adhesion force for the pinning of the water droplet on the micropost arrays is presented. Temperature and flow fields are predicted and the predictions of flow velocity inside the water droplet are validated through the particle image velocimetry (PIV). The Nusselt number variation for various sizes of the micropost arrays is obtained for two droplet volumes. It is found that reducing the solid fraction of micropost array beyond ϕs = 0.25, the Cassie and Baxter state of the surface changes to the Wenzel state; in which case, hydrophobic characteristics changes to hydrophilic characteristics for the water droplet. Heat transfer from the droplet bottom gives rise to development of the buoyancy and the Marangoni currents, which in turn generate two counter rotating circulation cells. The center of circulation cells moves further in the droplet upper part for the hydrophobic droplet case. The Nusselt number attains high values for the hydrophobic droplet at micropost array spacing size b = 10 μm and hydrophobic droplet at spacing size b = 50 μm due to fin effects of the micropost arrays.
Photovoltaic devices using hydrogenated amorphous silicon produced by the chemical vapor deposition of higher order silanes. Final report, 1 August 1982-31 August 1983 (1985)

This report presents the results of work performed to explore the properties of hydrogenated amorphous silicon (a-Si:H) produced by the chemical vapor deposition (CVD) of higher order silanes. The higher silanes were produced by a chemical method and by silent electric discharge of CCD-grade monosilane. The latter method yields a high-purity mixture of higher silanes. The a-Si:H films were deposited mainly from silane by a static CVD method: the heated reactor was purged and evacuated and then filled to the initial pressure desired with reactant gases. The extent of the deposition chemistry was monitored by the increase in pressure. At a predetermined increase in pressure, the system was quickly evacuated. This process was repeated several times to obtain a film of the desired thickness. These experiments were performed to increase our understanding of the deposition mechanism of a-Si:H, to improve the quality of CVD a-Si:H layers for device applications, to measure the properties of CVD a-Si:H doped and undoped layers, and to explore new device structures and alternative CVD techniques.
Nasal mask average volume‐assured pressure support in an infant with congenital central hypoventilation syndrome (2019)

Congenital central hypoventilation syndrome (CCHS) is a rare disorder characterized by alveolar hypoventilation and autonomic dysregulation secondary to mutations of the <i>PHOX 2B</i> genes. Treatment consists of assisted ventilation using positive pressure ventilators via tracheostomy, bi-level positive airway pressure (BPAP), negative pressure ventilators, or diaphragm pacing. Previous case reports have highlighted early use of nasal non-invasive BPAP use in infants with CCHS. We present a case of a 10-month-old infant who was successfully managed on a new feature of non-invasive ventilation called average volume assured pressure support (AVAPS) without the need for tracheostomy. The AVAPS feature enables the machine to automatically adjust the inspiratory pressures to deliver a constant targeted tidal volume. This feature enabled a better control of ventilation as indicated by a more stable transcutaneous carbon dioxide profile compared to conventional nasal non-invasive BPAP, making non-invasive ventilation a more accessible method of managing sleep hypoventilation in CCHS.
