PhoenixCloud: Provisioning Resources for Heterogeneous Cloud Workloads (2010)

As more and more service providers choose Cloud platforms, a resource provider needs to provision resources and supporting runtime environments (REs) for heterogeneous workloads in different scenarios. Previous work fails to resolve this issue in several ways: (1) it fails to pay attention to diverse RE requirements, and does not enable creating coordinated REs on demand; (2) few work investigates coordinated resource provisioning for heterogeneous workloads. In this paper, our contributions are three-fold: (1) we present an RE agreement that expresses diverse RE requirements, and build an innovative system PhoenixCloud that enables a resource provider to create REs on demand according to RE agreements; (2) we propose two coordinated resource provisioning solutions for heterogeneous workloads in two typical Cloud scenarios: first, a large organization operates a private Cloud for two heterogeneous workloads; second, a large organization or two service providers running heterogeneous workloads revert to a public Cloud; and (3) A comprehensive evaluation has been performed in experiments. For typical workload traces of parallel batch jobs and Web services, our experiments show that: a) In the first Cloud scenario, when the throughput is almost same like that of a dedicated cluster system, our solution decreases the configuration size of cluster by about 40%; b) in the second scenario, our solution decreases not only the total resource consumption, but also the peak resource consumption maximally to 31% with respect to that of EC2 + RightScale solution.
Metadata-Aware Measures for Answer Summarization in Community Question Answering (2010)

My thesis report presents a framework for automatically processing information coming from community Question Answering (cQA) portals. The purpose is that of automatically generating a summary in response to a question posed by a human user in natural language. The goal is to ensure that such answer be as trustful, complete, relevant and succinct as possible. In order to do so, the author exploits the metadata intrinsically present in User Generated Content (UGC) to bias automatic multi-document summarization techniques toward higher quality information. The originality of this work lies in the fact that it adopts a representation of concepts alternative to n-grams, which is the standard choice for text summarization tasks; furthermore it proposes two concept-scoring functions based on the notion of semantic overlap. Experimental results on data drawn from Yahoo! Answers demonstrate the effectiveness of the presented method in terms of ROUGE scores. This shows that the information contained in the best answers voted by users of cQA portals can be successfully complemented by the proposed method.

Techniques to control or avoid cement around implant-retained restorations. (2013)

As implant dentistry has grown in popularity, many clinicians have attempted to simplify their protocols to more closely resemble conventional crown and bridge procedures. However, a thorough understanding of the biologic differences between natural teeth and dental implants, as well as the types of cements employed, is essential to achieving both short- and long-term success, as these biologic disparities between teeth and implants can lead to residual cement around implant-retained restorations, thus contributing to peri-implant disease. Four techniques are described that either reduce the flow of excessive cement or eliminate it altogether while maintaining proper occlusion without compromising the esthetics of implant-retained restorations.
All-inorganic cesium lead halide perovskite nanocrystals for photodetector applications (2015)

Herein, we describe simple, fast and reproducible halide ion exchange reactions in CsPbX3 (X = Cl, Br, I) nanocrystals (NCs) at room temperature. Through the simple adjustment of the halide ion concentration, the photoluminescence of these NCs can be tuned over the entire visible region (425-655 nm). Photodetector devices based on entirely inorganic CsPbI3 NCs are demonstrated for the first time. The photodetectors exhibited a good on/off photocurrent ratio of 10(5).
Mott–Schottky analysis of thin ZnO films (2000)

Thin ZnO films, both native and doped with secondary metal ions, have been prepared by sputter deposition and also by casting from solutions containing a range of precursor salts. The conductivity and infrared reflectivity of these films are subsequently enhanced chemically following treatment in H2 gas at 400 °C or by cathodic electrochemical treatment in a neutral (pH=7) phosphate buffer solution. While Hall-type measurements usually are used to evaluate the electrical properties of such films, the present study investigated whether a conventional Mott–Schottky analysis could be used to monitor the change in concentration of free carriers in these films before and after chemical and electrochemical reduction. The Mott–Schottky approach would be particularly appropriate for electrochemically modified films since the measurements could be made in the same electrolyte used for the post-deposition electrochemical processing. Results of studies on sputtered pure ZnO films in ferricyanide solution were promising. Mott–Schottky plots were linear and gave free carrier concentrations typical for undoped semiconductors. Film thicknesses estimated from the Mott–Schottky data were also reasonably close to thicknesses calculated from reflectance measurements. Studies on solution-deposited films were less successful. Mott–Schottky plots were nonlinear, apparently due to film porosity. A combination of dc polarization and atomic force microscopy measurements confirmed this conclusion. The results suggest that Mott–Schottky analysis would be suitable for characterizing solution-deposited ZnO films only after extensive modeling was performed to incorporate the effects of film porosity on the characteristics of the space-charge region of the semiconductor.
Boosting Coded Dynamic Features for Facial Action Units and Facial Expression Recognition (2007)

It is well known that how to extract dynamical features is a key issue for video based face analysis. In this paper, we present a novel approach of facial action units (AU) and expression recognition based on coded dynamical features. In order to capture the dynamical characteristics of facial events, we design the dynamical haar-like features to represent the temporal variations of facial events. Inspired by the binary pattern coding, we further encode the dynamic haar-like features into binary pattern features, which are useful to construct weak classifiers for boosting learning. Finally the Adaboost is performed to learn a set of discriminating coded dynamic features for facial active units and expression recognition. Experiments on the CMU expression database and our own facial AU database show its encouraging performance.
Dispersion compensation techniques for CATV lightwave transmission systems (2002)

Summary form only given. Analog transmission of CATV signals has made rapid strides in the past few years with the deployment of 1550 nm external modulation systems and high power optical amplifiers. Such systems have extended the reach of analog systems to over 125 km. With such long links, several linear and nonlinear mechanisms that lead to signal degradation have to be considered. These mechanisms include dispersion, double Rayleigh backscattering (DRBS), phase modulation to intensity modulation (PM-IM) conversion, SBS and SPM acting singly or in combination. Fiber nonlinearities for the most part do not degrade the CATV system distortions unless they interact with dispersion. So dispersion compensation effectively combats the effect of nonlinearities also, provided the dispersion compensation can be achieved without any additional nonlinearity. It is also theoretically possible to use dispersion as a means of combating the effect of nonlinearities. Models to show this effect will be presented at the conference, along with experimental results.

Deciphering the relative roles of matrix metalloproteinase‐ and plasmin‐mediated matrix degradation during capillary morphogenesis using engineered hydrogels (2019)

Extracellular matrix (ECM) remodeling is essential for the process of capillary morphogenesis. Here we employed synthetic poly(ethylene glycol) (PEG) hydrogels engineered with proteolytic specificity to either matrix metalloproteinases (MMPs), plasmin, or both to investigate the relative contributions of MMP- and plasmin-mediated ECM remodeling to vessel formation in a 3D-model of capillary self-assembly analogous to vasculogenesis. We first demonstrated a role for both MMP- and plasmin-mediated mechanisms of ECM remodeling in an endothelial-fibroblast co-culture model of vasculogenesis in fibrin hydrogels using inhibitors of MMPs and plasmin. When this co-culture model was employed in engineered PEG hydrogels with selective protease sensitivity, we observed robust capillary morphogenesis only in MMP-sensitive matrices. Fibroblast spreading in plasmin-selective hydrogels confirmed this difference was due to protease preference by endothelial cells, not due to limitations of the matrix itself. In hydrogels engineered with crosslinks that were dually susceptible to MMPs and plasmin, capillary morphogenesis was unchanged. These findings highlight the critical importance of MMP-mediated degradation during vasculogenesis and provide strong evidence to justify the preferential selection of MMP-degradable peptide crosslinkers in synthetic hydrogels used to study vascular morphogenesis and promote vascularization. © 2019 Wiley Periodicals, Inc.

Surface modification and modulation in microstructures: controlling protein adsorption, monolayer desorption and micro-self-assembly (2003)

The surface-to-volume ratio increases with decreasing scale, thus, controlling and changing the surface properties of microstructures can be a powerful tool in the design, fabrication and use of microsystems. This paper overviews several recent projects that utilize the modulation of surfaces from hydrophobic to hydrophilic and vice versa, or from protein adsorbing to non-fouling, with applications in biomedical microdevices and self-assembling microelectromechanical systems.

On Tensor Train Rank Minimization: Statistical Efficiency and Scalable Algorithm (2017)

Tensor train (TT) decomposition provides a space-efficient representation for higher-order tensors. Despite its advantage, we face two crucial limitations when we apply the TT decomposition to machine learning problems: the lack of statistical theory and of scalable algorithms. In this paper, we address the limitations. First, we introduce a convex relaxation of the TT decomposition problem and derive its error bound for the tensor completion task. Next, we develop an alternating optimization method with a randomization technique, in which the time complexity is as efficient as the space complexity is. In experiments, we numerically confirm the derived bounds and empirically demonstrate the performance of our method with a real higher-order tensor.
Upscaling faces for recognition systems using trained filters (2009)

Face recognition systems which perform in unconstrained environment needs to cope with vary input resolutions. Low resolution input images are often quite problematic. This paper describes the improvement obtained on facial expression recognition and identity recognition when applying resolution upscaling methods based on trained filter techniques. In this paper, we explore the method proposed by Kondo et al. Kondo's methode has already been applied in display technology successfully, but hasn't been studied for recognition tasks before. In addition, we examine the influence on the recognition performance of the type of material exploited to train the upscaling filters, by selecting both generic videos and face images as samples. We then analyze how the size of the training set used in generating the upscaling filters influence the recognition rates. We show that adopting faces as training material produces upscaling filters capable of both higher recognition performance and much reduced requirements on the training size.
Evaluation of Standard Methods for the Analysis of Methyl <i>tert</i>-Butyl Ether and Related Oxygenates in Gasoline-Contaminated Groundwater (2001)

The U.S. Environmental Protection Agency (EPA) now requires monitoring of oxygenate compounds in groundwater at leaking underground storage tank (LUST) sites nationwide. Three purge-and-trap gas chromatography methods most commonly employed for this purpose were tested, and their performance as a function of total petroleum hydrocarbon (TPH) content of the sample matrix was determined. Tests included a formal method evaluation, a round-robin study, and a split-sample study (424 groundwater samples). Consistently good results were achieved with EPA Method 8240B/60B (mass spectrometry) and ASTM Method D4815 (flame ionization detection) when five oxygenates were monitored in reagent water and gasoline. However, one protocol routinely employed for analysis of LUST samples had serious limitations: EPA Method 8020A/21B (photoiozination detection) was unfit for monitoring of tert-butyl alcohol (TBA) and frequently yielded false-positive (12-50% of samples) and inaccurate results when ether oxygenates were monitored in aqueous samples containing high concentrations of TPH (> 1,000 microg/ L). Thus, care should be taken in the analysis of LUST databases populated with EPA Method 8020/21 data because results reported for methyl tert-butyl ether (MTBE) in samples containing high levels of TPH have a high likelihood of being inaccurate or false-positive. For all three methods, detection limits determined in reagent water were sufficiently low for monitoring MTBE at the stringent primary (13 microg/L) and secondary (5 microg/L) action levels set by the state of California.
<title>Lenticular Sheet 3-D Pictures And 3-D Projections</title> (1980)

The concept of lenticular sheet 3-D pictures dates from the beginning of this century. This method is responsible of commercial 3-D post-cards and 3-D photographic portraits. New applications are presented in this paper. They concern two domains where direct holographic 3-D reconstructions are impossible. These applications are the 3-D reconstruction of electron microscope pictures and the 3-D projection on a lenticular screen.
Understanding the Characteristics of Mobile Augmented Reality Applications (2018)

Recently, augmented reality technologies are debuting to the mainstream markets. Currently, smartphones are still the dominant computing platform for providing mobile augmented reality (MAR) experience to users. Nevertheless, MAR on smartphones faces some key challenges as the rich functionalities increase concerns including battery power drain and thermal dissipation. This paper takes the first step to understand the characteristics of MAR apps from the system and architecture perspectives. We observe that MAR apps exhibit much higher Thread-level Parallelism (TLP) and have a potential to better exploit the big.LITTLE architecture. We further build Multi-comPonent Power and Thermal Analysis Tool (MPPTAT) on Android mobile platform to break down the power consumption and thermal dissipation into hardware components, threads, and phases. Power characterization shows that MAR apps exhibit higher energy consumption compared to other popular mobile non-MAR apps, mainly contributed by the camera. Thread level breakdown shows that the major CPU power consumption is MediaServer, which controls the camera to capture and process multimedia information on smartphones. We also investigate the impact of DVFS, and results indicate that current MAR apps' implementations are mostly CPU intensive and the mobile GPU is not well exploited yet. Moreover, thermal characterization shows that compared to the non-MAR apps, the frequent usage of the camera not only increases the temperature of the camera module but also dissipates the heat to other layers, which directly affect user experience. We believe that our work reveals insights for software and hardware designers to fine-tune augmented reality workloads on mobile platforms.

In conjunction to this, the gallery is also interested in constructing a framework of references.
Credit Risk, Credit Scoring, and the Performance of Home Mortgages (1996)

This article examines the ways institutions involved in mortgage lending assess credit risk and how credit risk relates to loan performance. An increasingly prominent tool used to facilitate the assessment of credit risk in mortgage lending is credit scoring based on credit history and other pertinent data, and the article presents new information about the distribution of credit scores across population groups and how credit scores relate to the performance of loans. In addition, this article takes a special look at the performance of loans made through nontraditional underwriting practices and &amp;amp;quot;affordable&amp;amp;quot; home lending programs.
Tris-borate is a poor counterion for RNA: a cautionary tale for RNA folding studies (2004)

Native polyacrylamide gel electrophoresis is a powerful approach for visualizing RNA folding states and folding intermediates. Tris-borate has a high-buffering capacity and is therefore widely used in electrophoresis-based investigations of RNA structure and folding. However, the effectiveness of Tris-borate as a counterion for RNA has not been systematically investigated. In a recirculated Hepes/KCl buffer, the catalytic core of the bI5 group I intron RNA undergoes a conformational collapse characterized by a bulk transition midpoint, or Mg1/2, of approximately 3 mM, consistent with extensive independent biochemical experiments. In contrast, in Tris-borate, RNA collapse has a much smaller apparent Mg1/2, equal to 0.1 mM, because in this buffer the RNA undergoes a different, large amplitude, folding transition at low Mg2+ concentrations. Analysis of structural neighbors using a short-lived, RNA-tethered, photocrosslinker indicates that the global RNA structure eventually converges in the two buffer systems, as the divalent ion concentration approaches approximately 1 mM Mg2+. The weak capacity of Tris-borate to stabilize RNA folding may reflect relatively unfavorable interactions between the bulky Tris-borate ion and RNA or partial coordination of RNA functional groups by borate. Under some conditions, Tris-borate is a poor counterion for RNA and its use merits careful evaluation in RNA folding studies.
Hypoglycemic activity of Eugenia jambolana and Ficus bengalensis: mechanism of action. (1992)

The extract of jaman pulp from fruit of Eugenia jambolana showed hypoplycemic activity. This report is the first evidence of such activity in relation to pulp. The effect of pulp was seen in 30 min, while the seeds of the same fruit required 24 hr. The extracts of bark of Ficus bengalensis caused reduction in blood sugar level. These results were confirmed in streptozotocin-induced diabetic animals. The oral administration of the extract resulted in enhancement in serum insulin levels in normoglycemic and diabetic rats. The incubation of isolated islets of Langerhans from normal as well as from diabetic animals with each of these plant extracts stimulated insulin secretion. These extracts inhibited insulinase activity from liver and kidney.
