A Theoretical Study of the O (<sup>3</sup>P) + HCONH<sub>2</sub> Reaction (2013)

The triplet potential surface of the O ( 3 P) + HCONH 2 reaction has been investigated at the CCSD (T)//B3LYP/6-311G (d,p) level. DFT calculations show that the reaction occurs dominantly via the H - abstraction rather than the O- addition mechanism on the triplet potential surface. The product of OH and CONH 2 should be the major product, which obtained by a direct dissociation of the adduct im6 without an exit barrier.
Flatworm Control of Mosquito Larvae in Rice Fields (1979)

We describe some flatworms (some in the genus Mesostoma ) that kill mosquito larvae and may account for the variability in the population densities of Culex tarsalis and Anopheles freeborni in rice fields. When mosquito larvae brush against these worms, the larvae immediately become paralyzed and die. When C. tarsalis larvae are placed inside floating cages that exclude flatworms (50-micromter mesh), there is a fourfold increase in their survival. Rice fields that have abundant mosquito populations lack flatworms. Most such fields have only recently been turned over to rice production, suggesting that the flatworms have difficulty dispersing to new fields but, once established, are able to overwinter and control mosquitoes for the subsequent years of rice production.
Evaluation of cisplatin dose intensity: current status and future prospects. (1989)

Cisplatin dose intensity is a potentially important concept in the chemotherapeutic management of several human malignancies. In vitro studies have demonstrated steep dose-response relationships in a variety of tumor types. Although previous clinical trials have also suggested the importance of cisplatin dose, renal insufficiency has limited exploration of more dose-intensive regimens. Recently, therapeutic strategies such as hypertonic saline have allowed dose escalation to the level of 200 mg/m2/28 day cycle, or 50 mg/m2/week as standardized for dose intensity analysis. In this review, we summarize the rationale for investigation of cisplatin dose intensity, pertinent pharmacokinetics, and potential methods of dose escalation. Clinical data are presented regarding both efficacy and newly recognized non-renal toxicities of high-dose cisplatin. We describe the results of a pharmacokinetically designed schedule of high-dose cisplatin in hypertonic saline, administering a divided dose of 100 mg/m2 on days 1 and 8 of each 28-day cycle. This regimen has resulted in high response rates and encouraging survival times in non-small cell lung cancer, and is currently being investigated in several different tumor types. Compared to other dose-intensive regimens, this day 1 and 8 schedule is relatively well-tolerated, with a toxicity pattern not substantially different from standard-dose cisplatin. Since non-renal toxicities such as peripheral neuropathy continue to limit cumulative cisplatin dose, other methods of increasing dose intensity are of considerable interest. We present the rationale and current trials utilizing chemoprotective or "rescue" agents as a means of maximizing cisplatin dose intensity and minimizing the toxicity of this agent.

Dewatering of Activated Sludge by an Oxidative Treatment (1993)

Different activated sludges from pulp and paper mills were treated with hydrogen peroxide in the presence of ferrous sulphate under different reaction conditions in order to improve the dewatering characteristics of the sludges. The efficiency of the treatment was evaluated on the basis of the specific filtration resistance. Although sludges from different mills varied considerably with respect to their chemical composition and dewatering properties, the specific resistance values of all the sludges could be decreased using rather mild conditions. The filterabilities of the sludges were dependent on reaction temperature, hydrogen peroxide concentration and the reaction time used in the oxidative treatment. Depending on the type of sludge, hydrogen peroxide concentrations of 15 to 30 % mmoles/l sludge were sufficient to decrease the filtration values to a low level at 70°C using a reaction time of 1-2 hours at pH 3.

Markov Chain Model for Performance Analysis of Transmitter Power Control in Wireless MAC Protocol: Towards Delay Minimization in Power-network Control (2007)

Delay, one of the most important parameters in the wireless control networks, is largely dependent on the packet length when using contention based medium access control (MAC) protocol in single hop networks. In this paper, we have developed a three-state discrete time Markov-chain based model for the performance evaluation of MAC protocol. Using this Markov-chain model, we analyze the carrier sense multiple access (CSMA) MAC protocol for its delay and throughput characteristics in the presence of transmitter power control. Using simulations, we measure the probability of capture (which gives a measure of the effectiveness of transmitter power control due to the capture effect.) and validate these simulated data experimentally. To analyze the effect of transmitter power variation, the Markovchain model is modified by incorporating the probability of capture. Numerical results are obtained to measure the performance improvement.
Scalable model for dynamic configuration and power management in virtualized heterogeneous web clusters (2015)

This paper presents a model for dynamic configuration of Virtualized Application Servers (VAS) based on an algorithm of linear complexity, achieving the scalability needed for big data centers and cloud computing platforms. The goal is to minimize the power consumption of the processing environment and maintenance of the quality of service (QoS) of the applications. The experiments evaluate our model as compared to the Linux CPU governors and a state-of-the-art approach based on optimization. The results show that our model conserves up to 49.6% of the energy required by a cluster designed for peak workload scenario, with a negligible impact on the applications performance.

High efficiency photovoltaic conversion with spectrum splitting on GaAs and Si cells located in light confining cavities (2002)

A high-efficiency photovoltaic conversion system based on spectrum splitting of concentrated light to fall on GaAs and Si cells placed inside light confining cavities is described and experimental results are reported: 29.4% at 180 suns (near AM1.5 direct spectrum), 22% contributed by the GaAs cell. The short-circuit current gain derived from the use of the cavities is 7-8% (relative increase). However, the system is believed to have immediate potential to achieve as much as 32% efficiency. Benefits compared to systems based on stacked cells are pointed out: (a) conventional cells based on developed fabrication techniques can be used, with minor design changes, (b) cell design can be independently optimized with the aim of achieving maximum efficiency, (c) cells can operate at different concentrations, (d) electrical power can be extracted independently from each cell, and (e) it is easy to make the electrical connections to each cell.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Predicting 3D Human Dynamics From Video (2019)

Given a video of a person in action, we can easily guess the 3D future motion of the person. In this work, we present perhaps the first approach for predicting a future 3D mesh model sequence of a person from past video input. We do this for periodic motions such as walking and also actions like bowling and squatting seen in sports or workout videos. While there has been a surge of future prediction problems in computer vision, most approaches predict 3D future from 3D past or 2D future from 2D past inputs. In this work, we focus on the problem of predicting 3D future motion from past image sequences, which has a plethora of practical applications in autonomous systems that must operate safely around people from visual inputs. Inspired by the success of autoregressive models in language modeling tasks, we learn an intermediate latent space on which we predict the future. This effectively facilitates autoregressive predictions when the input differs from the output domain. Our approach can be trained on video sequences obtained in-the-wild without 3D ground truth labels. The project website with videos can be found at https://jasonyzhang.com/phd.
Assessment of GaN Surface Pretreatment for Atomic Layer Deposited High-<i>k</i>Dielectrics (2011)

We report the effects of GaN surface pretreatments on the material and electrical properties of Al2O3 dielectric deposited by atomic layer deposition (ALD). A layer of Al2O3 was deposited at different temperatures on metal organic chemical vapor deposition grown n-GaN that was treated with either H2O2:H2SO4 (1:5, piranha), HCl:H2O (1:1, HCl), or HF:H2O (1:1, HF) prior to Al2O3 deposition. The Al2O3 layers on piranha- and HF-treated GaN were observed to be uniformly smooth. The piranha pretreatment resulted in the lowest hysteresis. Pretreatment of the GaN surface with piranha removes carbon and hydroxylates the surface, resulting in better quality ALD Al2O3.
Novel Glass-Forming Liquid Crystals. 6. High-Temperature Glassy Nematics (2001)

To furnish new insight into structure−property relationships governing glassy nematic liquid crystals, novel material systems were synthesized and characterized. Highly ordered, solid films were also prepared via spin-coating for the determination of optical birefringence. It was found that a linear nematogen, such as the cyanoterphenyl group, contributes to an elevated glass transition temperature and a wide nematic fluid temperature range with a mixed or an extended core structure. However, an angular nematogen, such as the cyanophenylnaphthyl group, is more versatile in inducing glass formation with a broader range of core structures. Morphologically stable, glassy nematics with a Tg close to 130 °C, a Tc close to 350 °C, a nematic fluid temperature range of 265 °C, and an optical birefringence of 0.44 accomplished in this study represent significant improvements over existing materials. A stereochemical modification of the bicyclooctene ring from an exo-, exo- to an endo-, and exo-configuration, fluorination of the cyanophenylnaphthyl group, and a longer spacer to nematic pendants were found to depress Tc to a much greater extent than Tg. An extension in the core structure accompanied by an increased number of nematic pendants per core was found to elevate Tg, but no consistent effect on Tc was observed.
Waterborne giardiasis at a mountain resort: evidence for acquired immunity. (1984)

In November 1981, an outbreak of waterborne giardiasis occurred at a popular ski resort in Colorado. Stratification of illness by consumption of municipal tap water showed a striking dose-response, with an attack rate of 42 per cent among persons who drank six or more glasses of water per day. Filtered water samples revealed Giardia cysts in specimens both before and after treatment, and several deficiencies were found in the water treatment facility. Residents who had lived in the area greater than 2 years had a lower attack rate for illness than short-term residents.
Pedestrian Simultaneous Localization and Mapping in Multistory Buildings Using Inertial Sensors (2014)

Pedestrian navigation is an important ingredient for efficient multimodal transportation, such as guidance within large transportation infrastructures. A requirement is accurate positioning of people in indoor multistory environments. To achieve this, maps of the environment play a very important role. FootSLAM is an algorithm based on the simultaneous localization and mapping (SLAM) principle that relies on human odometry, i.e., measurements of a pedestrian's steps, to build probabilistic maps of human motion for such environments and can be applied using crowdsourcing. In this paper, we extend FootSLAM to multistory buildings following a Bayesian derivation. Our approach employs a particle filter and partitions the map space into a grid of adjacent hexagonal prisms with eight faces. We model the vertical component of the odometry errors using an autoregressive integrated moving average (ARIMA) model and extend the geographic tree-based data structure that efficiently stores the probabilistic map, allowing real-time processing. We present the multistory FootSLAM maps that were created from three data sets collected in different buildings (one large office building and two university buildings). Hereby, the user was only carrying a single foot-mounted inertial measurement unit (IMU). We believe the resulting maps to be strong evidence of the robustness of FootSLAM. This paper raises the future possibility of crowdsourced indoor mapping and accurate navigation using other forms of human odometry, e.g., obtained with the low-cost and nonintrusive sensors of a handheld smartphone.

Role of the Type III Secretion System in a Hypervirulent Lineage of <i>Bordetella bronchiseptica</i> (2009)

Despite the fact that closely related bacteria can cause different levels of disease, the genetic changes that cause some isolates to be more pathogenic than others are generally not well understood. We use a combination of approaches to determine which factors contribute to the increased virulence of a Bordetella bronchiseptica lineage. A strain isolated from a host with B. bronchiseptica-induced disease, strain 1289, was 60-fold more virulent in mice than one isolated from an asymptomatically infected host, strain RB50. Transcriptome analysis and quantitative reverse transcription-PCR showed that the type III secretion system (TTSS) genes were more highly expressed by strain 1289 than strain RB50. Compared to strain RB50, strain 1289 exhibited greater TTSS-mediated cytotoxicity of a mammalian cell line. Additionally, we show that the increase in virulence of strain 1289 compared to that of RB50 was partially attributable to the TTSS. Using multilocus sequence typing, we identified another strain from the same lineage as strain 1289. Similar to strain 1289, we implicate the TTSS in the increased virulence of this strain. Together, our data suggest that the TTSS is involved in the increased virulence of a B. bronchiseptica lineage which appears to be disproportionately associated with disease. These data are consistent with the view that B. bronchiseptica lineages can have different levels of virulence, which may contribute to this species' ability to cause different severities of respiratory disease.

Towards a Rigorous Formulation of the Space Mapping Technique for Engineering Design (2005)

The paper deals with the space mapping (SM) approach to engineering design optimization. We attempt a theoretical justification of methods that have already proven efficient in solving practical problems, especially in the RF and microwave area. A formal definition of optimization algorithms using surrogate models based on SM technology is given. Convergence conditions for the chosen subclass of algorithms are discussed and explained using a synthetic example, the so-called generalized cheese-cutting problem. An illustrative, circuit-theory based example is also considered.
Multivariate Time Series Modeling for Long Term Partial Discharge Measurements in Medium Voltage XLPE Cables (2019)

A multivariate time series analysis was performed for a system of several PD response variables, i.e. average charge, number of discharge pulses, average charge current, and largest repetitive discharge magnitude over the data acquisition period. Experimental lifelong PD data obtained from cable samples subjected to accelerated degradation was used to study the dynamic trends and relationships among those aforementioned response variables. Stochastically formulated cointegrated variables recognized by those tests can be combined to form new stationary variables to estimate the parameters for the Vector Auto Regression (VAR) and Vector-Error Correction (VEC) models. The validity of both models was evaluated by generating Monte Carlo and Minimum Mean Squared Error (MMSE) simulated forecasts. True observed data and forecasted data mean values lie within the 95 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> percentile confidence interval responses which demonstrates the soundness and accuracy of both models. A life-predicting model based on the cointegrating relations between the multiple response variables, correlated with experimentally evaluated time-to-breakdown values, can be used to set an emergent alarming trigger and as a step towards establishing long-term continuous monitoring of partial discharge activity.
Deploying virtual machines as sandboxes for the grid (2005)

The ability to securely run arbitrary untrusted code on a wide variety of execution platforms is a challenging problem in the Grid community. One way to achieve this is to run the code inside a contained, isolated environment, namely a &quot;sandbox&quot;. Virtual machines provide a natural solution to the security and resource management issues that arise in sandboxing. We explore different designs for the VM-enabled sandbox and evaluate them with respect to various factors like structure, security guarantees, user convenience, feasibility and overheads in one such grid environment. Our experiments indicate that the use of on-demand VMs imposes a constant startup overhead, with I/O-intensive applications incurring additional overheads depending on the design of the sandbox.
A Multi-Constellations Satellite Selection Algorithm for Integrated Global Navigation Satellite Systems (2009)

The U.S. Global Positioning System (GPS) is currently the only fully operational global navigation satellite system (GNSS) that has been widely utilized in navigation and data collection, among other applications. In the near future, there will be other GNSSs such as the Russian GLONASS, the European Galileo, and the Chinese Compass that provide compatible services with GPS and will be available to all users. Besides operating in the single GNSS mode, future GNSS receivers will have the capability to operate in an integrated GNSS mode where they will be able to couple satellites from all available constellations for positioning solutions. However, tracking all visible satellites simultaneously increases the computational load of the receivers. This is particularly true with low-cost and compact receivers, which have limited computational resources and are commonly used in real-time intelligent transportation system (ITS) applications such as automatic vehicle location, route guidance, fleet management, vehicle dispatch, traveler information, and car navigation. These real-time applications also impose time constraints on positional updates (maximum required time interval between two epochs) while requiring high accuracy positioning solutions. To mitigate such burdens while maintaining benefits of the combined system, this article presents a new heuristic algorithm called a multi-constellations satellite selection algorithm (MCSSA). The algorithm allows an integrated GNSS receiver to track only a smaller set of visible satellites that can provide acceptable positioning solutions in the required time intervals. The MCSSA considers the geometric arrangements of visible satellites and selects the ones that spread evenly over the observed sky view. The performance of the MCSSA was validated by simulating the combined GPS and Galileo constellations. The accuracy and computation time of the MCSSA were compared with selected existing satellite selection algorithms. The results indicate that the MCSSA provides the set of satellites with near-optimal geometries giving high positional accuracy in a reasonably small computation time and thus is suitable for real-time applications.
