People re-detection using Adaboost with sift and color correlogram (2008)

People re-detection aims at performing re-identification of people who leave the scene and reappear after some time. This is an important problem especially in video surveillance scenarios. In this paper, we present a method of people re-detection within the context of visual sequence in single-camera setup. We consider re-detection as a binary classification problem, where both global and local descriptors are employed for training strong classifier on-line with Adaboost to distinguish a newly detected people as tracked or new occurrence. The strong classifier will be updated while match is ascertained. A predetermined classifier with well-chosen threshold is employed as assistant of training examples collection. We test the performance of our approach on 4 different scenes including 51 video sequences taken from the CAVIAR database and 4 video sequences shot by ourselves. The results show that our re-detection algorithm can robustly handle variations in illumination, pose, scale, and camera-view.
Electric Drives for Propulsion System of Transport Aircraft (2016)

Following the hybridization or complete electrification strategy of the electric drive pursued on terrestrial vehicles, the aviation industry is considering with great attention the application of electrical technology and power electronics for transport aircraft. The growing interest toward electric application in transport aircraft is driven by the ambitious targets for aviation declared by Europe and by the United States of America and is motivated by the growing evidence that evolutionary improvement of the technologies might not be sufficient to fulfill these targets. As a result, the introduction of disruptive technologies turns out to be essential. With respect to the progress and perspective in electrical technology, electric drive applications to transport aircraft reveals itself to be a promising field in view of meeting the future goals. The focus of this chapter is the assessment of the electrification of the propulsion system of transport aircraft. While aiming for the ultimate goal of universally electric aircraft, hybrid electric approach will be first necessary to match the requirement of aircraft propulsion system and the development pace of the electrical components technology. The combinatorial variety of hybrid electric and universally electric propulsion system topology considered for transport aircraft application as well as key enabling technologies are first reviewed. A compendium of hybrid electric and universally electric advanced aircraft concepts is then proposed to obtain a notion of the cloud of aircraft configurations and electric drive options investigated up to this point in time. Finally, the integrated prospects of hybrid electric aircraft are investigated to establish the feasibility of hybrid electric aircraft for future market segments.
Embedded nonvolatile memories (2002)

The embedded nonvolatile memories (NVM) offer in-system reprogrammability along with low power, noise reduction. more reliable, and reduced system cost while maintain high speed, high density system performance over other NVM including stand-alone flash memory. The extent of market opportunity is driven by product cost. For most applications, manufacturability is the primary concern for embedded NVM, not cell size. The design simplicity is a key factor when choosing cell design. Another area of concern for cell design is the integration compatibility of the logic core process to the additional NVM flow. In this paper we review different NVM concepts from ROM to flash, and to FeRAM, and their applications in support of the diverse and emerging consumer market.
Controlled 3D Buckling of Silicon Nanowires for Stretchable Electronics (2010)

Silicon (Si) nanowire (NW) coils were fabricated on elastomeric substrates by a controlled buckling process. Si NWs were first transferred onto prestrained and ultraviolet/ozone (UVO)-treated poly(dimethylsiloxane) (PDMS) substrates and buckled upon release of the prestrain. Two buckling modes (the in-plane wavy mode and the three-dimensional coiled mode) were found; a transition between them was achieved by controlling the UVO treatment of PDMS. Structural characterization revealed that the NW coils were oval-shaped. The oval-shaped NW coils exhibited very large stretchability up to the failure strain of PDMS (∼104% in our study). Such a large stretchability relies on the effectiveness of the coil shape in mitigating the maximum local strain, with a mechanics that is similar to the motion of a coil spring. Single NW devices based on coiled NWs were demonstrated with a nearly constant electrical response in a large strain range. In addition to the wavy shape, the coil shape represents an effective architecture in accommodating large tension, compression, bending, and twist, which may find important applications for stretchable electronics and other stretchable technologies.

Complexing of heparin with phosphatidylcholine. A possible supramolecular assembly of plasma heparin (1985)

In a series of attempts to reveal plasma heparin, we found that high ionic strength and modification of protein amino groups were not effective in extracting endogenous heparin (or, indeed, a large percentage of exogenous labelled heparin), whereas delipidation in the presence of 4M-guanidinium chloride gave high yields, indicating that plasma heparin may be assembled with compounds other than proteins, in a form making it inaccessible to water and ions. During the extraction of lipids, a paradoxical entry of heparin into the organic phase was observed. Detergents, including sodium dodecyl sulphate, did not shift heparin into the aqueous phase, whereas repeated chloroform/methanol extraction did so. Using purified compounds we were able to reproduce in vitro both the scavenging of heparin from water as well as the formation of heparin-phosphatidylcholine complexes soluble in organic solvents. Evidence for complexing of heparin with phosphatidylcholine was also obtained by electrophoretic and ultracentrifugation assays. The quaternary-ammonium-containing phosphatidylcholine was the more effective phospholipid in binding heparin; anionic phospholipids did not bind. Only heparin-like glycosaminoglycans bound phosphatidylcholine, but less-sulphated compounds (heparan sulphate and dermatan sulphate) were weaker ligands. Gel-filtration experiments showed that heparin was not bound to liposome vesicles, but that a measurable percentage of the phospholipids was stripped off from vesicles and was found in the form of a complex separable from liposomes by gel filtration. The molecular basis as well as the biological role of the interaction of heparin with major membrane phospholipids are discussed.

Cytokines in dermatology. (2006)

Cytokines are polypeptides that are produced by various cell types and act in an autocrine or paracrine manner. They have many different biological actions and have been used in dermatology to treat a wide range of dermatologic diseases. In this paper we review some of the more commonly used cytokines in dermatology, including interferon-alpha and -gamma, interleukins-2 and -10, and granulocyte-macrophage colony-stimulating factor. We specifically examine their roles in the treatment of condyloma and verruca, hemangiomas, keloids, skin cancers, atopic dermatitis, psoriasis, Behcet disease, chronic granulomatous disease, wound healing, and cutaneous T cell lymphoma. In addition, some of the adverse effects associated with these cytokines are discussed.
Cis‐elements and trans‐factors that regulate expression of the maize Cat1 antioxidant gene in response to ABA and osmotic stress: H<sub>2</sub>O<sub>2</sub> is the likely intermediary signaling molecule for the response (2000)

The mechanisms by which the maize antioxidant Cat1 gene responds to abscisic acid (ABA) and osmotic stress have been investigated. Results show that during late embryogenesis, Cat1 expression in vivo is independent of endogenous ABA levels. However, exogenously applied ABA significantly enhances Cat1 expression. Transient assays using particle bombardment show that the proximal ABRE2 element on the Cat1 promoter is responsible for the induction of Cat1 expression by ABA. We further show that ABA induces the expression of Cat1 via the interaction between ABRE2 and one of its binding proteins, CBF1 (Cat1 binding factor 1). Using ABA-deficient mutant embryos, we show that osmotic stress induces Cat1 expression through two alternate signal transduction pathways: an ABA signaling pathway leading to the interaction between the ABRE2 motif and CBF1, and a pathway via the interaction of ABRE2 and CBF2 (Cat1 binding factor 2) that is independent of ABA. The data presented clearly suggest that hydrogen peroxide (H2O2) plays an important intermediary role in the ABA signal transduction pathway leading to the induction of the Cat1 gene.

A Concise History of Modern Painting (1960)

Comprehensive, authoritative, highly readable and generously illustrated, Herbert Read's text has been rightly acknowledged as far the best introduction to the subject (Alan Bowness) and throughout, lively and closely packed (Hugh Casson). Here is modern painting from its roots in the work of Cezanne, through Cubism, Futurism, Surrealism and Dada in the early decades of the twentieth century and on to Abstract Expressionism in the 1950s. The works of Frank Stella, Richard Hamilton, Andy Warhol and Robert Rauschenberg, amongst many others, are discussed and analyzed by Caroline Tisdall and William Feaver in a lively final chapter that brings us up to present times and points to exciting new developments. 500 illus., 118 in color.
Experimental and Clinical Pharmacology of<i>Andrographis paniculata</i>and Its Major Bioactive Phytoconstituent Andrographolide (2013)

Andrographis paniculata (Burm. F) Nees, generally known as "king of bitters," is an herbaceous plant in the family Acanthaceae. In China, India, Thailand, and Malaysia, this plant has been widely used for treating sore throat, flu, and upper respiratory tract infections. Andrographolide, a major bioactive chemical constituent of the plant, has shown anticancer potential in various investigations. Andrographolide and its derivatives have anti-inflammatory effects in experimental models asthma, stroke, and arthritis. In recent years, pharmaceutical chemists have synthesized numerous andrographolide derivatives, which exhibit essential pharmacological activities such as those that are anti-inflammatory, antibacterial, antitumor, antidiabetic, anti-HIV, antifeedant, and antiviral. However, what is noteworthy about this paper is summarizing the effects of andrographolide against cardiovascular disease, platelet activation, infertility, and NF- κ B activation. Therefore, this paper is intended to provide evidence reported in relevant literature on qualitative research to assist scientists in isolating and characterizing bioactive compounds.

Alkylation of <i>H</i>-Phosphinate Esters under Basic Conditions (2007)

An efficient and general procedure was developed for the direct alkylation of H-phosphinate esters with LHMDS at low temperature. The simplicity of the reaction allows the use of various H-phosphinate esters and takes place with a wide range of electrophiles. The approach can be employed to access some GABA analogues or precursors to GABA analogues. The isolated yields are moderate to good. This is the first report of an alkylation with a secondary iodide or a primary chloride.
Role and Importance of Phenoloxidase in Insect Hemostasis (2010)

In response to microbial infection, insects mount several defense reactions including the induction of proteolytic cascades that lead to localized melanization and coagulation. Melanization requires the activation of prophenoloxidase (proPO) to its active form phenoloxidase (PO), a key enzyme that leads to the formation of melanin at wound sites and around intruding microorganisms in the hemolymph. Clotting is critical in limiting hemolymph loss and initiating wound healing following injury; it quickly acts to form a solid barrier against infection by immobilizing microorganisms and promoting their killing. Recent advances in Drosophila and other insects imply a possible link between PO and the coagulation system, although the exact molecular mechanisms controlling this interaction appear to be complex and are still not well defined. The development of hemolymph experimental techniques in Drosophila larvae together with proteomic analysis have further led to the identification of proPO as a cross-linking component that is involved in the hardening and melanization of clots. However, clot PO activity varies between insect species and life stages, depending on physiological and ecological conditions. Here we review our current knowledge of the association between PO and coagulation and discuss the implications of the previous findings on insect innate immunity and hemostasis.
Cancer patterns in Canada. (1986)

Cancer is diagnosed in about 70 000 Canadians each year and is the leading cause of the loss of potential years of life before age 75 among women. Life-threatening forms of cancer will develop in at least one of every three Canadian newborns during their lifetimes if current cancer risks are not reduced. Lung and breast cancers are, respectively, the leading causes of premature death due to cancer among men and women. Compared with other countries Canada has low death rates for stomach cancer but high rates for certain smoking-related cancers (those of the lung and of the mouth and throat), leukemia and cancers of the colon, breast and lymphatic tissues. Newfoundland has the highest rates of death from stomach cancer and the lowest rates of death from prostatic cancer, whereas the western provinces have the opposite pattern. The rates of death from lung cancer among men are highest in Quebec, the province with the highest prevalence of smoking. In Canada the overall rates of death from cancer increased by 32% among men from 1951 to 1983. However, among women they declined by 12% from 1951 to 1976 and increased from 1976 to 1983, particularly among those aged 55 to 74. The rising rates of death due to lung cancer were primarily responsible for these increases. Lung cancer will likely displace breast cancer as the leading cancer killer of Canadian women by 1990. Given the relatively low survival rates for cancers caused by smoking and the lack of substantial improvement in rates for the most frequent types of cancer, preventive strategies that include effective measures to reduce tobacco consumption are urgently required.

Friction blisters and sock fiber composition. A double-blind study (1990)

A longitudinal double-blind study was conducted to determine the effect of sock fiber composition on the frequency and size of blistering events in long-distance runners. Thirty-five long-distance runners participated in this study. Two different socks were tested, which were identical in every aspect of construction except fiber composition. One test sock was composed of 100% acrylic fibers, and the other test sock was composed of 100% natural cotton fibers. The results showed that acrylic fiber socks were associated with fewer blistering events and smaller blisters (mm2), when compared directly to cotton fiber socks.
Isoflurane's Effect on Protein Conformation as a Proposed Mechanism for Preconditioning (2011)

Persistent alteration of protein conformation due to interaction with isoflurane may be a novel molecular aspect of preconditioning. We preincubated human serum albumin with isoflurane, dialyzed to release agent, and assessed protein conformation. Susceptibility to chemical modification by methylglyoxal and nitrophenylacetate was also examined. Isoflurane had a persistent effect on protein conformation. An increase in the susceptibility of surface residues to chemical modification attended this change in conformation. Modification of isoflurane-treated HSA included intra- and intersubunit cross-linking that may be a consequence of anesthetic-induced changes in multimeric subpopulations. This irreversible effect of isoflurane may represent a mechanism for preconditioning.
SOCIAL MEDIA BRAND COMMUNITY AND CONSUMER PURCHASE: A CROSS-BRAND ANALYSIS (2012)

Social media brand communities have been widely adopted by marketers as a marketing channel to engage consumers, and by consumers as a source of product/brand information prior to their purchase decisions. The popularity of social media brand communities has attracted some academic research efforts. However, there still exist important research gaps to be addressed in the existing literature. First, previous studies only focused on the impact of consumers? engagement in the community of a brand on their purchases from that particular brand. However, consumers could have preference for multiple brands within a product class. As such, the impact of engagement in the community of a brand on consumers' purchases from other preferred alternative brands remains unknown. Second, previous studies implicitly assumed that consumers only engage in a single community of a preferred brand. However, consumers would engage in multiple communities of multiple preferred brands within a product class. As such, the impact of consumers' engagement in communities of multiple similar brands on their purchases from those engaged brands also remains unknown. This study thus proposes a set of research hypotheses, aiming to fill these research gaps. The findings from this study would offer several notable theoretical contributions.
