Anomaly Detection through Enhanced Sentiment Analysis on Social Media Data (2014)

Anomaly detection in sentiment analysis refers to detecting abnormal opinions, sentiment patterns or special temporal aspects of such patterns in a collection of data. The anomalies detected may be due to sudden sentiment changes hidden in large amounts of text. If these anomalies are undetected or poorly managed, the consequences may be severe, e.g. A business whose customers reveal negative sentiments and will no longer support the establishment. Social media platforms, such as Twitter, provide a vast source of information, which includes user feedback, opinion and information on most issues. Many organizations also leverage social media platforms to publish information about events, products, services, policies and other topics frequently. Thus, analyzing social media data to identify abnormal events in a timely manner is a beneficial topic. It will enable the businesses and government organizations to intervene early or adopt proper strategies if needed. However, it is also a challenge due to the diversity and size of social media data. In this study, we survey existing anomaly analysis as well as sentiment analysis methods and analyze their limitations and challenges. To tackle the challenges, an enhanced sentiment classification method is proposed and discussed. We study the possibility of employing the proposed method to perform anomaly detection through sentiment analysis on social media data. We tested the applicability and robustness of the method through sentiment analysis on tweet data. The results demonstrate the capabilities of the proposed method and provide meaningful insights into this research area.

Attentional Demands and Postural Recovery: The Effects of Aging (1999)

The ability to recover a stable posture following an external perturbation is more attentionally demanding for older adults than for younger adults. This would suggest that for some older adults, an increased risk for loss of balance and falls may result if sufficient attentional resources are not allocated to the task of postural recovery.
Hardware Obfuscation Using Strong PUFs (2018)

IC piracy is a significant security threat, where malicious manufacturers can produce unauthorized extra chips and/or steal the information of a design through reverse engineering attempts. As a countermeasure, hardware obfuscation schemes usually withhold a part of the design (which thereafter constitutes the "key") by replacing it with configurable modules. Enforcing the configurable module to be filled in with the withheld key information enables a post-manufacturing activation of each authenticate chip, albeit with a a need to state the threat of a leaked common key. To ensure that each chip has a unique key, Physically Unclonable Functions (PUFs) have been proposed to be integrated with hardware obfuscation. Such a paradigm is constrained to use weak PUFs, because, to uniquely set the key (the content of the configurable module) for each chip, the designer needs to fully characterize the PUFs for all the chips. In this paper, we argue that a powerful attacker in the position of a manufacturer can fully characterize all the weak PUFs, and use any leaked key to break the obfuscation framework. This paper proposes a strong PUF-based hardware obfuscation scheme to effectively prevent IC piracy even in the case of a leaked key from some activated chip.
The McLean County JDC: An Evaluative Tool for Determining the Feasibility of Outsourcing Juvenile Detention (1994)

The purpose of this research is to compose a systematic procedure, using cost-benefit analysis, to determine the feasibility of expanding government services by adding juvenile detention facilities, as opposed to outsourcing juvenile detention to other nearby counties.
EFFECT OF EXCESSIVE SECRETION OF GROWTH HORMONE ON TISSUES OF THE RAT, WITH PARTICULAR REFERENCE TO THE HEART AND SKELETAL MUSCLE (1980)

Rat pituitary tumours of the GH3 cell line, secreting growth hormone (GH), were induced to grow in Wistar-Furth rats and the effect of prolonged excessive secretion of GH on various organs was investigated. Total body weight of the tumour-bearing animals increased by over 100% compared with control animals and there was widespread visceromegaly affecting especially the liver, kidney, spleen and adrenals. The heart was also considerably enlarged. The effects of excessive GH on skeletal muscle were not uniform and, using a histochemical technique, it was found that the size type 1 muscle fibres was increased to the greatest extent whereas fibre type 2A was unaffected. Synthesis of DNA in the heart and skeletal muscle was also increased in tumour-bearing animals. Removal of the tumours was followed by a considerable regression in the size of most organs, although hypertrophy of the heart was affected least by a return to normal plasma levels of GH. It was concluded that animals bearing GH3 cell tumours provide a useful experimental model for the study of the tissue changes in acromegaly.
Risks of milk formulas containing peanut oil contaminated with peanut allergens in infants with atopic dermatitis (1994)

Four cases of infants with atopic dermatitis are reported. In all cases, a sensitization to peanut is demonstrated. Any ingestion of peanuts can be excluded, with the exception of a daily consumption of peanut oil, contained in milk formulas. Oral challenges with peanut oil induce a rash, and elimination of these brands is followed by the disappearance of eczematous lesions. The presence of residual allergenic proteins in peanut oil is thus suspected. Owing to the growing incidence of peanut hypersensitivity, the elimination of peanut oil from all milk formulas, food for babies, and ointments, seems to be highly advisable.
TEFM is a potent stimulator of mitochondrial transcription elongation in vitro (2015)

A single-subunit RNA polymerase, POLRMT, transcribes the mitochondrial genome in human cells. Recently, a factor termed as the mitochondrial transcription elongation factor, TEFM, was shown to stimulate transcription elongation in vivo, but its effect in vitro was relatively modest. In the current work, we have isolated active TEFM in recombinant form and used a reconstituted in vitro transcription system to characterize its activities. We show that TEFM strongly promotes POLRMT processivity as it dramatically stimulates the formation of longer transcripts. TEFM also abolishes premature transcription termination at conserved sequence block II, an event that has been linked to primer formation during initiation of mtDNA synthesis. We show that POLRMT pauses at a wide range of sites in a given DNA sequence. In the absence of TEFM, this leads to termination; however, the presence of TEFM abolishes this effect and aids POLRMT in continuation of transcription. Further, we show that TEFM substantially increases the POLRMT affinity to an elongation-like DNA:RNA template. In combination with previously published in vivo observations, our data establish TEFM as an essential component of the mitochondrial transcription machinery.
A ternary pulse compression code: Design and application to radar system (2010)

In this paper, we present new developed ternary code - punctured binary sequence-pair, give its definitions and the autocorrelation properties. We also investigate Doppler shift performance of the proposed code. The significant advantages of this ternary codes over conventional pulse compression codes, such as the widely used Barker codes, are zero autocorrelation sidelobes and the longer length of the code which can be as long as 31 so far. We apply our new ternary codes to radar system for target detection and observe that our codes outperform some other conventional pulse compression codes.
<title>Highly automated nonparametric statistical learning for autonomous target recognition</title> (1992)

Image pattern recognition is presented as three sequential tasks: feature extraction, object plausibility estimation (determining class likelihoods), and decision processing. Several data- driven techniques yield discriminant functions to produce object plausibility estimates from image features, including traditional statistical methods and neural network approaches. A statistical learning algorithm which integrates multiple-regression algorithms, functional networking strategies, and a statistical modeling criterion is presented. It provides a non- parametric learning algorithm for the synthesis of discriminant functions. Image understanding tasks such as object plausibility estimation require robust modeling techniques to deal with the uncertainty prevalent in real-world data. Specifically, these complex tasks require robust and cost-effective techniques to successfully integrate multi-source information. AbTech and others have shown that implementation of the statistical learning concepts discussed provide a modeling approach ideal for information fusion tasks such as autonomous object recognition for tactical targets and space-based assets. The results of using this approach to develop a prototype aircraft recognition system is presented.

Abstract magnified image The in situ prepared three component system [RhCl(COD)] 2 /imidazolidinium salts ( 2, 4 ) and KOBu t catalyses the addition of phenylboronic acid to sterically hindered aldehydes affording the corresponding arylated secondary alcohols in good yields. Four novel 1,3‐dialkylimidazolidinium ( 2‐4 ) salts as NHC precursors were synthesized from N,N′ ‐dialkylethylenediamine.
Differential Studies of Alkali Catalysed Production of Biodiesel from Sorghum Oil (2014)

Conventional energy sources that is petroleum fuel reserve are depleting day by day which has led the world to think about non-conventional fuels and other major concerning issue is about eco-friendly environment and it pull the search for ecofriendly renewable fuel. Biodiesel is non-toxic, biodegradable and contributes a minimal amount of net greenhouse gases. A study was conducted to produce biodiesel from sorghum oil by transesterification process. The volumetric ratio, catalyst type NaOH, KOH and concentration are some important parameters that affect the quality and yielding of biodiesel that also fulfil the ASTM D6751 standard. For yielding highest percentage (92.9) of biodiesel, the ideal condition were 5:1 molar ratio of sorghum oil to ethanol, 1.0% NaOH catalyst, reaction time 90 minutes, temperature 60°C and 300 rpm stirring speed. While using 1.0% of NaOH and KOH as catalyst, higher amount of biodiesel was yielded in NaOH as comparing to KOH catalyst and biodiesel yielding were maximum in 1.0% NaOH catalyst as compared to 0.5% and 1.5% NaOH catalyst. At different parameters a minor difference in viscosity, acid value, and saponification value was observed. The detailed study has revealed that efficient biodiesel can be produced from sorghum oil under optimized conditions and appropriates catalyst concentration.
IL‐10 and the resolution of infections (2007)

Chronic viral infections pose serious health concerns, as secondary complications such as immunodeficiencies and cancers are common. Treating such infections with conventional vaccine approaches has proved to be difficult. Studies in animals and humans suggest that vaccine failure is probably due to exhaustion of antiviral T cell responses, which occurs in a number of chronic infections. Attempts to elucidate the causes of impairment of antiviral immunity have pointed to a role for the immunomodulatory cytokine IL-10 in the ability of viruses to establish persistence. Induction of IL-10 production by the host during chronic infection appears to be one of the viral means to alter the class of the antiviral immune response and induce generalized immune suppression. Recent work by us and others suggests that it is possible to resuscitate antiviral immunity by interfering with the IL-10 signalling pathway. Targeting IL-10 thus constitutes a promising alternative to conventional vaccine strategies which have not proved to be successful in treating chronic infections. In addition, sterile cure may be achieved with minimal side-effects by combining agents that alter the IL-10 signalling pathway with other compounds, such as antiviral drugs or interferon, but also agents neutralizing other crucial elements of T cell exhaustion, such as PD-1.
Beyond Earth: Designing Root Zone Environments for Reduced Gravity Conditions (2012)

Fluid management in plant root zones is critical for long duration space missions including lunar‐ or Martian‐based missions, but key aspects of design and delivery of fluids under these conditions are poorly understood due to limited experimental opportunities. We review theoretical and experimental concepts for advancing understanding of fluid‐porous media interactions to improve design and management of plant‐based life support systems for reduced gravity environments. In situ utilization of native lunar and Martian granular materials for plant‐growth media requires reliable characterization of media physical and hydraulic properties and processes. A key aspect is the enhanced effects of capillarity in reduced gravity resulting in an array of micro‐ and macroscale changes in fluid phase organization relative to conditions on Earth that may affect mass fluxes to plant roots and potentially result in excess water and hypoxia. Increasing the medium particle diameter above 1 mm and narrowing the distribution of particles, and thus pore sizes, may counter reduced gravity effects. Approaches used in previous microgravity systems involving sensor‐based active water management assuming prescribed optimal set points (i.e., water potential) may fail in reduced gravity due to dynamic pore space alterations arising from air‐ or liquid‐phase entrapment and root growth in a restricted volume that may alter the porous medium characteristics on which water management is often based. For example, about a 10% reduction in volumetric pore space was observed following rice ( Oryza sativa L.) root growth, which could change a well‐aerated root zone into an anoxic environment if not accounted for. Numerical modeling of plant transpiration and irrigation using volumetrically controlled water content under different gravity environments revealed similar hydraulic responses in fine‐textured porous media typically unsuitable for plant growth in greenhouses. Volumetric water content–based management of plant root environments appears to be a safer approach than other methods discussed here.

Polyurethane acrylate/epoxy-amine acrylate hybrid polymer networks (2000)

New classes of hybrid polymer networks (HPNs), having variable polyurethane acrylate (PUA) and epoxy–amine acrylate (EAA) compositions, were prepared using initially miscible systems in methyl methacrylate (MMA). The initial systems were based on PUA prepolymer and EAA monomer solutions in MMA. HPNs were a result of epoxy–amine and radical polymerization competition. Phase separation occurred during the course of HPN formation. Mechanical dynamic analysis of the prepared HPNs showed good affinity between the PUA and PMMA phases and lower affinity between the EAA and PMMA phases. Mechanical property evolution and transmission electronic microscopy showed that, for all the composition ranges used in this study (PUA/EAA/PMMA 15/45/40–45/15/40 wt %), the PUA-rich phase was the continuous phase. EAA-rich phases, 20–50 nm, in the PUA-rich matrix were obtained for HPNs containing up to 30 wt % EAA. For higher EAA concentration (45 wt %), 2 μm EAA-rich phases were obtained in the PUA-rich matrix. A substructure was also observed in each phase. PUA/EAA copolymers were prepared and used successfully for the compatibilization of the different phases of the HPNs. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 77: 2711–2717, 2000

Isabel: An Application for real time Collaboration with a flexible Floor Control (2006)

Isabel is a P2P like multipoint group collaboration tool for the Internet, which implements an innovative service concept for synchronous collaborations based on a flexible and programmable floor control. This approach leads to a more natural and effective management of collaboration sessions. The flexible and programmable floor control incorporates the experience gained in many years of service trials with real users in distributed conferences, classrooms or meetings. The main conclusion after all those trials is that services should use more or less the same media components (audio, video or application sharing), but differ in the floor control model used. The flexible floor control is especially well suited for multipoint audience interconnection in distributed classrooms, conferences, meetings, etc. The development of Isabel started in 1993 for the distribution of the RACE Summer Schools on Advanced Broadband Communication (ABC93-6) where the early versions of this service concept were developed and tuned. The effectiveness of the Isabel service concept has been proven and enhanced since then in many other distributed events, such as Global360x, IDC9x, Global IPv6 Summitts, Telecom I+D, etc. The adaptation of Isabel to the broadband Internet (including VPNs, IPv4/IPv6 transition scenarios, mixtures of unicast and multicast) has reached maturity recently
夢魘抑或希望？:露薏絲•勞瑞的《記憶傳授人》與青少年反烏托邦文學 (2013)

Lois Lowry’s The Giver, an adolescent dystopian novel, gains more and more credit today from both young readers and critics of adolescent literature. With the understated narrative, Lowry presents a dystopian world where people do not have memory under the mind control and scientific regulation of the authority. This thesis aims to analyze the system of the community of The Giver by examining its power and technological control over people to see the impact of such a regime on adolescents. Furthermore, the loss of memory, perception and concept of life and death results in an untraditional experience of adolescent growth and development in the novel. This thesis will inspect different aspects of adolescence in this context of the novel and explore the issues of memory, death and liminal adolescence.
 The rising tendency of depicting teenagers as social hope or young hero in adolescent literature is also a distinguishing feature in the dystopian context of The Giver. These days adolescent literature tends to disclose the dark side of the world and corrupted adult society, and thus young protagonists are given the role of a gifted young hero or a foreseer with superpower to change the status quo as in The Giver. There are more and more inspiration and reflection brought by this genre of young hero in young adult novels, and this will contribute to the evaluation of values and ideology of the present world by young readers in this world today.
Limitations and capabilities of directions-of-arrival estimation techniques using an array of antennas: a mobile communications perspective (2002)

Application of antenna array processing has been suggested for mobile communication systems to overcome the problem of limited channel bandwidth and to satisfy an ever growing demand that the large number of mobiles put on the channel. Application of the array processing requires either a knowledge of a reference signal or the direction of the desired signal source to achieve its desired objectives. There exists a range of schemes to estimate the direction of arrival with conflicting demands of accuracy and processing power. This paper provides a tutorial treatment of direction-of-arrival estimation schemes covering a review of many existing direction-of-arrival (DOA) estimation methods including their performance, sensitivities and limitations.
Metabolic Profiles of Propofol and Fospropofol: Clinical and Forensic Interpretative Aspects (2018)

Propofol is an intravenous short-acting anesthetic widely used to induce and maintain general anesthesia and to provide procedural sedation. The potential for propofol dependency and abuse has been recognized, and several cases of accidental overdose and suicide have emerged, mostly among the health professionals. Different studies have demonstrated an unpredictable interindividual variability of propofol pharmacokinetics and pharmacodynamics with forensic and clinical adverse relevant outcomes (e.g., pronounced respiratory and cardiac depression), namely, due to polymorphisms in the UDP-glucuronosyltransferase and cytochrome P450 isoforms and drugs administered concurrently. In this work the pharmacokinetics of propofol and fospropofol with particular focus on metabolic pathways is fully reviewed. It is concluded that knowing the metabolism of propofol may lead to the development of new clues to help further toxicological and clinical interpretations and to reduce serious adverse reactions such as respiratory failure, metabolic acidosis, rhabdomyolysis, cardiac bradyarrhythmias, hypotension and myocardial failure, anaphylaxis, hypertriglyceridemia, renal failure, hepatomegaly, hepatic steatosis, acute pancreatitis, abuse, and death. Particularly, further studies aiming to characterize polymorphic enzymes involved in the metabolic pathway, the development of additional routine forensic toxicological analysis, and the relatively new field of ‘‘omics’’ technology, namely, metabolomics, can offer more in explaining the unpredictable interindividual variability.
