A Deep Learning Model for Source Code Generation (2019)

Natural Language Processing (NLP) models have been used extensively to study relationship among words in a corpus. Inspired by models such as n-gram we developed a model for analyzing source code via its Abstract Syntax Tree (AST). This study has applications in source code generation, code completion, and software forensics and investigation. The study also benefits software developers and programmers striving to improve code efficiency and speed up development process. With source code analysis, the Natural Language Tool Kit (NLTK) which is very useful in NLP, becomes severely limited by its inability to handle the semantic and syntactic properties of source codes. Therefore, we processed the source code datasets as Abstract Syntax Trees (ASTs) rather than the source code text itself to take advantage of the information-rich structure of the AST. The proposed model is built on the deep learning-based Long Short-Term Memory (LSTM) and Multiple Layer Perceptron (MLP) architectures. Results from our intrinsic evaluation on a corpus of python projects have demonstrated its ability of effectively predicting a sequence of source code tokens and show an improvement over previous work in this field.
Privacy-Preserving Classification of Customer Data without Loss of Accuracy (2005)

Privacy has become an increasingly important issue in data mining. In this paper, we consider a scenario in which a data miner surveys a large number of customers to learn classification rules on their data, while the sensitive attributes of these customers need to be protected. Solutions have been proposed to address this problem using randomization techniques. Such solutions exhibit a tradeoff of accuracy and privacy: the more each customer's private information is protected, the less accurate result the miner obtains; conversely, the more accurate the result, the less privacy for the customers. In this paper, we propose a simple cryptographic approach that is efficient even in a many-customer setting, provides strong privacy for each customer, and does not lose any accuracy as the cost of privacy. Our key technical contribution is a privacy-preserving method that allows a data miner to compute frequencies of values or tuples of values in the customers’ data, without revealing the privacy-sensitive part of the data. Unlike general-purpose cryptographic protocols, this method requires no interaction between customers, and each customer only needs to send a single flow of communication to the data miner. However, we are still able to ensure that nothing about the sensitive data beyond the desired frequencies is revealed to the data miner. To illustrate the power of our approach, we use our frequency mining computation to obtain a privacy-preserving naive Bayes classifier learning algorithm. Initial experimental results demonstrate the practical efficiency of our solution. We also suggest some other applications of privacy-preserving frequency mining.
Studies on vascular permeability in hypertension: action of anthocyanosides. (1986)

The initial phase of renal hypertension induced by ligature of the abdominal aorta was accompanied by a transient increase in vascular permeability. This permeability increase has not the same intensity in all parts of the organism: it is greater in the skin and in the aorta wall than in the brain vessels. Treatment of rats with a flavonoid-type drug (anthocyanosides of Vaccinium myrtillus) for 12 days before the induction of hypertension kept the blood-brain barrier permeability normal and limited the increase in vascular permeability in the skin and the aorta wall. As previously demonstrated, the collagens of the blood vessel walls play an important role in the control of vascular permeability. Interaction of these collagens with the drug may be partly responsible for the protection against the permeability-increasing action of hypertension observed in the treated animals.
The Response Bounds of Unknown Nonlinear Systems With Sinusoidal Input (2008)

This paper studies the bounds of the response of a class of nonlinear systems with sinusoidal inputs. The unknown nonlinear system is assumed to have a unique steady-state response for a given input under different initial conditions. The sufficient condition of this assumption is given, and the bounds of the transient response and the steady-state response are derived in the sense of 2-norm and L <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> norm, respectively. A simulation example is presented to demonstrate the results.
The effect of gate doping on the electrical conduction and reliability of thick gate oxides (2002)

Previous investigations have shown that excessive gate oxide leakage currents at negative gate potentials observed in MOS power products are due to the presence of phosphorus in the gate oxide. During polysilicon gate doping some phosphorus atoms may pile up at the PSi/SiO2 interface and also may diffuse into the gate oxide due to high diffusion temperatures and longer soaking times. Subsequent high temperatures and plasma processing steps result in the ionization of these atoms. The neutralization of these ions during negative gate voltage testing gives rise to abnormal gate oxide leakage currents. It is shown that the presence of any Column V element in the gate oxide, if ionized, will result in excessive gate oxide leakage currents at negative potentials. The level of excessive leakage will depend on the amount of pile up of the impurity at the polysilicon gate/SiO2 interface. Data show that abnormally high gate oxide leakages due to the presence of these impurities in the gate oxide of MOS, IGBT and MCT devices may adversely affect the yield and the long term reliability.

Brain docosahexaenoic acid uptake and metabolism (2018)

Docosahexaenoic acid (DHA) is the most abundant n-3 polyunsaturated fatty acid in the brain where it serves to regulate several important processes and, in addition, serves as a precursor to bioactive mediators. Given that the capacity of the brain to synthesize DHA locally is appreciably low, the uptake of DHA from circulating lipid pools is essential to maintaining homeostatic levels. Although, several plasma pools have been proposed to supply the brain with DHA, recent evidence suggests non-esterified-DHA and lysophosphatidylcholine-DHA are the primary sources. The uptake of DHA into the brain appears to be regulated by a number of complementary pathways associated with the activation and metabolism of DHA, and may provide mechanisms for enrichment of DHA within the brain. Following entry into the brain, DHA is esterified into and recycled amongst membrane phospholipids contributing the distribution of DHA in brain phospholipids. During neurotransmission and following brain injury, DHA is released from membrane phospholipids and converted to bioactive mediators which regulate signaling pathways important to synaptogenesis, cell survival, and neuroinflammation, and may be relevant to treating neurological diseases. In the present review, we provide a comprehensive overview of brain DHA metabolism, encompassing many of the pathways and key enzymatic regulators governing brain DHA uptake and metabolism. In addition, we focus on the release of non-esterified DHA and subsequent production of bioactive mediators and the evidence of their proposed activity within the brain. We also provide a brief review of the evidence from post-mortem brain analyses investigating DHA levels in the context of neurological disease and mood disorder, highlighting the current disparities within the field.

Divergence Analysis and Optimizations (2011)

The growing interest in GPU programming has brought renewed attention to the Single Instruction Multiple Data (SIMD) execution model. SIMD machines give application developers a tremendous computational power, however, the model also brings restrictions. In particular, processing elements (PEs) execute in lock-step, and may lose performance due to divergences caused by conditional branches. In face of divergences, some PEs execute, while others wait, this alternation ending when they reach a synchronization point. In this paper we introduce divergence analysis, a static analysis that determines which program variables will have the same values for every PE. This analysis is useful in three different ways: it improves the translation of SIMD code to non-SIMD CPUs, it helps developers to manually improve their SIMD applications, and it also guides the compiler in the optimization of SIMD programs. We demonstrate this last point by introducing branch fusion, a new compiler optimization that identifies, via a gene sequencing algorithm, chains of similarities between divergent program paths, and weaves these paths together as much as possible. Our implementation has been accepted in the Ocelot open-source CUDA compiler, and is publicly available. We have tested it on many industrial-strength GPU benchmarks, including Rodinia and the Nvidia's SDK. Our divergence analysis has a 34% false-positive rate, compared to the results of a dynamic profiler. Our automatic optimization adds a 3% speed-up onto parallel quick sort, a heavily optimized benchmark. Our manual optimizations extend this number to over 10%.
Clock distribution using coupled oscillators (2002)

This paper presents a robust, low complexity clock distribution technique applicable to both printed circuit boards and integrated circuits. The technique exploits the natural tendency of certain oscillators to lock in frequency and nearly lock in phase when coupled together. Experimental and theoretical results are presented that indicate the technique has the potential to dramatically reduce clock skew in digital circuits. A clock distribution architecture using the technique is proposed.

The Use of B Vitamins for Cutaneous Ulcerations Mimicking Pyoderma Gangrenosum in Patients With MTHFR Polymorphism (2011)

MTHFR polymorphisms should be part of a comprehensive laboratory evaluation during hypercoagulable workup. Vitamin supplementation with folic acid (B(9)), pyridoxine hydrochloride (B(6)), and cyanocobalamin (B(12)) may result in healing of cutaneous ulcerations in some patients with MTHFR mutations.
In Situ Measurement of Colorectal Polyps to Compare Video and Fiberoptic Endoscopes (1994)

The present study was performed to test the reliability of in situ measurements of colorectal polyps when comparing videoendoscopes with fiberoptic endoscopes. In 25 small rectosigmoid polyps 3-12 mm) removed endoscopically, in situ diameters were measured before polypectomy using both video- and fiberoptic endoscopes. Polaroid and videoprint pictures were taken for computerised analysis of the area of the polyps on the pictures. The results showed a good correlation between the polyp diameter measured with the videoendoscope and fiberoptic endoscope (r = 0.97), with no significant difference by parametric testing. The diameter and weight of the removed polyp also correlated well with the diameter measured in situ using videoendoscopes (r = 0.92 and 0.77, respectively) or fiberoptic endoscopes (r = 0.90 and 0.81, respectively). Furthermore, the weight of the removed polyp correlated reasonably well to the computerised area measurement, the correlation coefficient being r = 0.90 for fiberoptic endoscopes and r = 0.75 for videoendoscopes. We conclude that in situ polyp diameter measurements using videoendscopes and fiberoptic endoscopes are similarly reliable and sensitive, and both instruments can be used interchangeably in follow-up studies of polyp growth.
Dialogue (2007)

Representing the voices of characters in a story is an effective way of enlivening a narrative. A vital aspect of how we remember and grow close to fictional characters is the way they speak: their accents and dialects place them geographically and socially, while their verbal idiosyncrasies and catchphrases help to make them memorable, even endearing. In an oral narrative, a change in intonation and/or pace may be sufficient to indicate to the listener where the narrator is quoting from another. The process is more complicated when it comes to written narratives, as the writer has to deal with the transition between one channel of communication and another. Nevertheless, the conventions for representing speech have become well established whether the context is a news story, a biography, or a novel, and readers rarely stop to question why speech is laid out as it is. As well as adding variety to a narrative, representing the speech of those who take part in a narrated event, or who are somehow qualified to comment on what takes place, may also contribute importantly to the authenticity and authority of the story, as we appear to be told what happened from "the horse's mouth." It is difficult to imagine a narrative that does not include some kind of representation of speech, but the extent to which this is foregrounded varies considerably. The degree of directness of the report may also vary, but in this chapter I am concerned primarily with what has been termed direct or free direct speech, where the words of the characters appear to be reproduced verbatim and contribute significantly to the central action or plot.
Decatungstate Anion for Photocatalyzed “Window Ledge” Reactions (2016)

The majority of organic reactions are commonly carried out inside a lab, under a fume hood. A particular case is that of photochemical reactions, a field where the pioneering experiments by Giacomo Ciamician demonstrated more than one century ago that different processes can be carried out outdoors, for example, on the balcony of his own department, upon exposure of the reacting mixtures to sunlight. The main problem related to this chemistry of the "window ledge" is that most organic compounds are colorless and their absorption in the solar light region is in most cases negligible. Recently, the impressive development in the use of visible light absorbing photocatalysts (e.g., Ru<sup>II</sup> or Ir<sup>III</sup> complexes, as well as organic dyes) made light-induced processes convenient even for non-photochemistry practitioners. It is thus possible to easily perform the reactions by simply placing the reaction vessel in a sunny place outside the lab. However, most of these processes are based on single electron transfer (SET) reactions (photoredox catalysis). Other photocatalysts able to activate substrates via alternative paths, such as hydrogen atom transfer (HAT), are emerging. In the last years, we were deeply involved in the use of the decatungstate anion ([W<sub>10</sub>O<sub>32</sub>]<sup>4-</sup>, a polyoxometalate) in synthesis. Indeed, such a versatile species is able to promote the photocatalytic C-H activation of organic compounds via either SET or HAT reactions. Interestingly, though the absorption spectrum of [W<sub>10</sub>O<sub>32</sub>]<sup>4-</sup> does not extend into the visible region, it shows an overlap with solar light emission. In this Account, we provide an overview on the application of decatungstate salts as photocatalysts in window ledge chemistry. We initially discuss the nature of the photogenerated species involved in the mechanism of action of the anion, also supported by theoretical simulations. The first-formed excited state of the decatungstate anion decays rapidly to the active species, a dark state tagged wO, featuring the presence of electron-deficient oxygen centers. Next, we describe the main applications of decatungstate chemistry. A significant part of this Account is devoted to photocatalyzed synthesis (C-X bond formation, with X = C, N, O, and oxidations) carried out by adopting sunlight (or simulated solar light). This synthetic approach is versatile, and most of the reactions involved C-H activation in cycloalkanes, alkylaromatics, amides, ethers (1,4-dioxane, oxetane, benzodioxole, and THF), aldehydes, nitriles, and cyclopentanones, and the ensuing addition of the resulting radicals onto electron-deficient olefins. Finally, the increasing role of the decatungstate anion in water depollution and polymerization is briefly discussed.
2-Trimethylsilylethyl Sulfides in the von Braun Cyanogen Bromide Reaction:  Selective Preparation of Thiocyanates and Application to Nucleoside Chemistry (2002)

Mixed 2-(trimethylsilyl)ethyl sulfides were synthesized and used in the von Braun cyanogen bromide reaction for preparing selectively thiocyanates in high yield. We show here that this cleavage reaction is highly selective in methanol in comparison with the reaction of the corresponding non-silyl sulfide analogues. This reaction was applied to the synthesis of nucleosidic thiocyanates such as the new nucleosides 14 and 18 in the search for mechanism-based inhibitors of ribonucleoside diphosphate reductase and bioactive molecules. The selective cleavage is possible for sulfides bearing hydroxyl functions and aromatic rings. The reactions of cyanogen bromide as cyanating and brominating agent were observed for the first time under the same conditions with the naphthoxyhexyl 2-trimethylsilylethyl sulfide 7, which, treated with cyanogen bromide in dichloromethane, led selectively to the p-bromonaphthoxyhexyl thiocyanate 10 in 89% yield. Another reaction induced by cyanogen bromide was observed in dichloromethane with the 2-(trimethylsilylethyl)thio nucleoside 13, which gives the corresponding symmetrical disulfide 21 in good yield.
Vibration-Based Adaptive Novelty Detection Method for Monitoring Faults in a Kinematic Chain (2016)

This paper presents an adaptive novelty detection methodology applied to a kinematic chain for the monitoring of faults. The proposed approach has the premise that only information of the healthy operation of the machine is initially available and fault scenarios will eventually develop. This approach aims to cover some of the challenges presented when condition monitoring is applied under a continuous learning framework. The structure of the method is divided into two recursive stages: first, an offline stage for initialization and retraining of the feature reduction and novelty detection modules and, second, an online monitoring stage to continuously assess the condition of the machine. Contrary to classical static feature reduction approaches, the proposed method reformulates the features by employing first a Laplacian Score ranking and then the Fisher Score ranking for retraining. The proposed methodology is validated experimentally by monitoring the vibration measurements of a kinematic chain driven by an induction motor. Two faults are induced in the motor to validate the method performance to detect anomalies and adapt the feature reduction and novelty detection modules to the new information. The obtained results show the advantages of employing an adaptive approach for novelty detection and feature reduction making the proposed method suitable for industrial machinery diagnosis applications.
The antibacterial action of honey. An in vitro study. (1985)

The reported antibacterial effect of pure honey was evaluated by an in vitro study testing the growth of various Gram-positive and Gram-negative bacteria in media containing varying concentrations of honey. It was found that most pathogenic bacteria failed to grow in honey at a concentration of 40% and above. The possible mechanisms of this effect are briefly outlined.
Performance of access strategies for D-TASI over mobile radio fading channels (1987)

Demand Time Assigned Speech Interpolation (D-TASI) has been proposed as a means of more efficiently using the radio spectrum allocated to mobile radio systems. In the D-TASI system, the delay experienced in accessing the message channel in order to transmit a voice packet is a major obstacle to the practical implementation of the system.Access schemes for D-TASI are the subject of this paper. Three access schemes have been proposed and their theoretical models developed; computer software packages have also been developed to simulate the three proposed schemes—Aloha, Polling, and Table-driven. The probability of call blocking as a function of user population, voice channel traffic intensity and time-slot duration has been studied. It has been found that under fading conditions the Polling access scheme performs the best, closely followed by Slotted Aloha, The performance of the Table-driven scheme falls some way short of that of the other two schemes.
