Fast-handoff support in IEEE 802.11 wireless networks (2007)

With the advance of wireless local area network (WLAN) technology, handoff support has become one of the most important issues in IEEE 802.11 WLANs. However, the current IEEE 802.11 specification does not provide the fast handoff required for real-time multimedia applications. To support fast handoff in IEEE 802.11 networks, a number of fast-handoff schemes have been proposed in the literature. In this article we review these fast-handoff schemes and analyze their advantages and disadvantages qualitatively. After that, important design considerations for mobility support in future IEEE 802.11 networks are suggested. Also, we introduce a fast-handoff framework which adaptively meets different application requirements via a cross-layer approach.
Selective detection of cesium by a water-soluble fluorescent molecular sensor based on a calix[4]arene-bis(crown-6-ether) (2006)

A tetrasulfonated calixarene with two appended crowns, each including a dioxycoumarin fluorophore, is highly soluble in water and shows excellent selectivity for cesium ions.
First isolation of dengue 4 in the state of São Paulo, Brazil, 2011 (2012)

We report the first isolation of Dengue virus 4 (DENV-4) in the state of São Paulo, from two patients - one living in São José do Rio Preto and the other one in Paulo de Faria, both cities located in the Northwest region of the state. The virus isolations were accomplished in the clone C6/36 Aedes albopictus cell line, followed by indirect immunofluorescence assays, performed with type-specific monoclonal antibodies that showed positive reactions for DENV-4. The results were confirmed by Nested RT-PCR and Real-Time RT-PCR assays. The introduction of DENV-4 in a country that already has to deal with the transmission of three other serotypes increases the possibility of the occurrence of more severe cases of the disease. The importance of early detection of dengue cases, before the virus spreads and major outbreaks occur, should be emphasized.
Chemopreventive Effects of Deguelin, a Novel Akt Inhibitor, on Tobacco-Induced Lung Tumorigenesis (2005)

Tobacco carcinogens induce Akt activation and lung carcinogenesis. We previously demonstrated that deguelin, a natural plant product, specifically inhibits the proliferation of premalignant and malignant human bronchial epithelial cells by blocking Akt activation. To evaluate the ability of deguelin to block tobacco carcinogen-induced lung tumorigenesis, we evaluated the in vivo effects of deguelin on Akt activation and lung tumorigenesis in transgenic mice in which Akt expression was induced by tamoxifen and in 4-(methylnitrosoamino)-1-(3-pyridyl)-1-butanone (NNK)/benzo(a)pyrene (BaP)-treated A/J mice. Deguelin suppressed Akt activation in vivo, as measured by immunohistochemistry and immunoblotting, and statistically significantly reduced NNK/BaP-induced lung tumor multiplicity, volume, and load in A/J mice, as monitored by microcomputed tomography image analysis, with no detectable toxicity. These results indicate that deguelin warrants consideration as a chemopreventive agent for early-stage lung carcinogenesis in a clinical lung cancer chemoprevention trial.
Oleylamine in Nanoparticle Synthesis (2013)

Wet chemistry in organic solvents has proven highly efficient for the preparation of several types of metallic, metal-oxide, and semiconductor nanostructures. This Short Review focuses on the use of oleylamine (OAm) as a versatile reagent for the synthesis of various nanoparticle systems. We describe the ability of OAm to act as a surfactant, solvent, and reducing agent, as a function of other synthesis parameters. We also discuss the specific role of OAm either alone or in combination with other reactants, to form nanostructures using a variety of organic or inorganic compounds as precursors. In certain cases OAm can form complex compounds with the metal ions of the corresponding precursor, leading to metastable compounds that can act as secondary precursors and thus be decomposed in a controlled way to yield nanoparticles. We also point out that OAm-stabilized particles can often be dispersed in different organic solvents yielding solutions with enhanced colloidal stability over long times and the potential to find applications in a number of different fields.
Measles virus and C3 binding sites are distinct on membrane cofactor protein (CD46). (1995)

The human complement regulatory protein membrane cofactor protein (CD46) is the cellular receptor for measles virus (MV), whereas decay accelerating factor (DAF; CD55), a structurally similar complement regulatory protein, does not bind MV. To characterize the interaction between MV and CD46, mutants of the CD46 protein and hybrid molecules between CD46 and DAF were tested for their ability to act as MV receptors. The transmembrane domain and cytoplasmic tail of CD46 were not required for receptor function as cells expressing the CD46 extracellular domain linked to the glycosyl-phosphatidylinositol tail of DAF were rendered susceptible to MV infection. Chimeric proteins exchanging the four extracellular short consensus repeat (SCR) domains between CD46 and DAF indicated that only molecules with both SCR1 and SCR2 from CD46 allowed a productive MV infection. Further, monoclonal antibodies (mAbs) against SCR1 or SCR2 of CD46 blocked MV infection, whereas a mAb against SCR3 and SCR4 did not. The latter mAb blocks C3b/C4b binding (which maps to SCR3 and SCR4) whereas the former mAbs do not. Thus, our data indicate that both SCR1 and SCR2 make up the MV receptor determinant in CD46. These results also suggest avenues for development of therapeutic agents to inhibit MV binding and thus infection and disease.

Use and Consumption of Silver in Photographic Applications in the Printing Industry (1984)

Silver is chemically and economically the single most important raw material in the manufacture of high speed photographic films and papers. Volatile silver prices and ecological constraints have caused photographic manufacturers and their customers to focus on reduced usage, reduced consumption via recycling, and replacement of silver. The authors present a detailed analysis of use of silver in photographic products for the printing industry. Applications in newspapers and in commercial colour reproduction are dealt with as examples. Current developments in recycling of silver are described and a new processing machine with built-in silver recovery and low fixer consumption is presented in detail. Five technological developments in the graphic arts that have or will have considerable impact on the use of silver are explained. The authors build a solid foundation under their projections that consumption of silver in photography in general, and in the printing industry in particular, is declining despite increased usage in some market segments.
T-cell-mediated concomitant immunity to syngeneic tumors. I. Activated macrophages as the expressors of nonspecific immunity to unrelated tumors and bacterial parasites. (1977)

Progressive growth of the SA1 sarcoma was shown to result in the generation of a state of concomitant resistance to growth of a second implant of the same tumor. The responding lymph nodes of concomitantly immune mice were shown to contain theta-positive T cells that could specifically neutralize the growth of tumor cells in a normal test recipient. Nevertheless, the concomitantly immune host itself was capable to a limited extent of suppressing the growth of unrelated tumors. The generation of immunity, moreover, was associated with the generation of a powerful state of macrophage-mediated, nonspecific resistance to the bacterial parasite, Listeria monocytogenes. It was concluded that systemic macrophage activation was the consequence of the generation of T-cell-mediated immunity to the progressively growing tumor, and that this not only gave the host the capacity to inhibit the growth of unrelated tumors, but also to protect itself against microbial infection. The results gives credence to the view that macrophages play a central role in defense against microbial and neoplastic growth.
Sharing our experience using wave theories inversion for the determination of the local depth (2009)

The determination of the nearshore bathymetry by inverting the propagation of the wave field over shallow waters as observed by ground based X-band radar has became recently part of the coastal monitoring routing. In this investigation, four different wave theories, linear, solitary, modified cnoidal and Stokes extended to shallow waters, are inverted by using the Dispersive Surface Classificator, DiSC, methodology. This is the first time that the efficiency of the previously mentioned theories for the determination of the depth is validated with multibeam echosounder data acquired two days before the radar data acquisition. The performance of the four wave models for the extraction of the local depth is discussed. The resulted bathymetries in all cases are significant, but the sources of the error are different.
Lysosomal Enzyme Release from Human Leukocytes: Mediation by the Alternate Pathway of Complement Activation (1973)

Abstract The alternate pathway of complement activation has recently assumed an important role in the mediation of inflammation and tissue injury. We have found that complement activated via this pathway interacts with human polymorphonuclear leukocytes (PMN) in the absence of particulates and stimulates the selective release of lysosomal enzymes. Fresh human serum, after treatment with zymosan or cobra venom factor, yields a fluid phase component which induces cytochalasin B-treated PMN to release β-glucuronidase without leakage of cytoplasmic lactate dehydrogenase. Involvement of the alternate pathway of complement activation is evidenced by failure of serum to yield enzyme-releasing activity after pretreatment with rabbit antihuman C3 proactivator, 0.01 M EDTA but not 0.01 M EDTA, 0.02 M salicylaldoxime, 0.02 M hydrazine or by heating to 56°C for 30 min. Levels of C3 proactivator in treated sera correlated inversely with and perturbs the PMN plasma membrane sufficiently to cause lysosomal membrane perturbation, fusion, and ultimately lysosomal enzyme extrusion by a process of “reverse endocytosis.”
Constructing and managing appliances for cloud deployments from repositories of reusable components (2009)

In order to efficiently utilize Cloud Computing environments (more specifically, Infrastructure as a Service offerings), developers must be able to quickly incorporate their applications into integrated systems commonly called software appliances. This paper describes a system that can be used to construct and maintain software appliances called Conary. The core of Conary is a software configuration management system that places all the components included in an appliance in a versioned repository. The version control system properties of Conary’s software configuration management design naturally facilities image creation and updates. An approach utilizing Conary solves many of the challenges faced by adopters of Cloud Computing. 1
A fully integrated 24GHz UWB radar sensor for automotive applications (2009)

Radar-based advanced safety systems are crucial to reduce road accidents caused by driver inattention. An actual and pervasive adoption of radar technology requires the development of low-cost Silicon-integrated sensors, including microwave, analog, and digital blocks on a single chip, able to replace existing discrete electronics based on compound semiconductors. Indeed, the considerable advantage of silicon lies in its natural capability for integration that will enable a higher level of complexity in such sensors. This paper presents a fully integrated 24GHz UWD radar sensor implemented in a 0.13mum SiGe BiCMOS process. The UWB signal generation takes advantage of a PLL. The produced 24.125GHz carrier is properly BPSK modulated to increase sensor robustness within the entire SRR sensor network.

Modeling of shape memory alloy actuator and tracking control system with the model (2001)

There has been great demand for shape memory alloy (SMA) actuators within the field of micro-machines. However, the thermomechanical behavior of SMA actuators is too complicated to accurately predict their response. Moreover the tracking control accuracy of SMA actuators is limited due to the inherent hysteresis nonlinearity. The paper presents a model of an SMA actuator for use in mechanical design and a control system for compensating the hysteresis. First, the model based on constitutive laws developed by Brinson et al. (1996) and our proposed hysteresis model is demonstrated. Next, we propose a control system composed of a proportional integral derivative (PID) feedback loop and a feedforward loop. In the feedforward loop, the desired control input corresponding to the desired displacement is obtained from a static SMA model derived by modifying the classic Preisach hysteresis model. We also propose a method for identifying parameters of the hysteresis model. This methods demands only measurement of the major loop. Application of the control system to our developed SMA actuator shows that the tracking control performance is improved.
Impact of 802.11e EDCA on mixed TCP-based applications (2006)

There has been an explosive growth in the use of wireless LANs (WLANs) to support network applications ranging from web-browsing and file-sharing to voice calls. It is difficult to optimally configure WLAN components, such as access points (APs), to meet the quality-of-service requirements of the different applications, as well as ensuring flow-level fairness. Recent work has shown that the widely-deployed IEEE 802.11 MAC Distributed Coordination Function (DCF) is biased against downstream flows. The new IEEE 802.11e standard introduces QoS mechanisms, such as Enhanced Distributed Channel Access (EDCA), that allow this unfairness to be addressed. So far, only limited work has been done to evaluate the impact of these MAC protocols on TCP-based applications. In this paper, through ns-2 simulations, we evaluate the impact of EDCA on TCP application traffic consisting of both long and short-lived TCP flows. We find that the performance of TCP applications is very dependent upon the settings of the EDCA parameters and buffer lengths at the AP. We also show that the performance of the admission control strategy employed depends on the buffer lengths at the AP and the traffic intensity.
Novel optically variable color devices (2006)

The recently introduced ROLICURE<sup>TM</sup> PEARL is a novel optically variable device (OVD) ideally suited for security applications. It may hold high resolution images, (micro-) text or graphical designs. Upon tilt or rotation high contrast positive/negative flips are observed. The optical effect of these devices is based on a proprietary technology of Rolic and includes light scattering at patterned anisotropic microstructures. Since these microstructures are non-periodic no rainbow colors are generated, making these devices easy to authenticate and clearly distinguishable from standard holograms. In this paper, we describe how to modify the optical appearance of our - <i>a priori</i> - colorless ROLICURE<sup>TM</sup> PEARL feature by addition of distinct color-shift thus further increasing its level of protection and meeting design requirements. This is accomplished by optical interference at additional dielectric and metallic layers in combination with the ROLICURE<sup>TM</sup> PEARL scattering microstructure. Various configurations are conceivable and have been realised in our labs. Depending on the nature of its dielectric layers red, green and blue colors are obtained and respective photospectra will be presented. While the optical appearance remains attractively bright, excellent color saturation is achievable. Independently from the color-shift which originates from changes of the optical path length under various viewing angles, the contrast inversion of the image is still present and is visualized when the device is tilted or rotated. In general, images of these security devices are easily recognizable within wide viewing angles without need of a point light source.
The pilocarpine model of epilepsy: what have we learned? (2009)

The systemic administration of a potent muscarinic agonist pilocarpine in rats promotes sequential behavioral and electrographic changes that can be divided into 3 distinct periods: (a) an acute period that built up progressively into a limbic status epilepticus and that lasts 24 h, (b) a silent period with a progressive normalization of EEG and behavior which varies from 4 to 44 days, and (c) a chronic period with spontaneous recurrent seizures (SRSs). The main features of the SRSs observed during the long-term period resemble those of human complex partial seizures and recurs 2-3 times per week per animal. Therefore, the pilocarpine model of epilepsy is a valuable tool not only to study the pathogenesis of temporal lobe epilepsy in human condition, but also to evaluate potential antiepileptogenic drugs. This review concentrates on data from pilocarpine model of epilepsy.
Parameter Embedding Mode and Optimal Post-Process Filtering for Improved WDCT Image Compression (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> The warped discrete cosine transform (WDCT) has been shown to improve the compression performance compared to standard DCT for image compression at high bit rates. In the proposed approach, the WDCT parameters are embedded into the transform coefficients for low bit rates in the form of a watermark to avoid the WDCT parameter side information overhead, improving the compression performance for low bit rates. Furthermore, optimal postprocess filtering, with filter coefficients being determined at the encoder and multiplexed into the bit stream, is proposed to improve the quality of the decoded image through postprocess filtering at the decoder. It is shown that a significant gain in quality can be achieved by the postprocess filtering. As optimal postprocess filtering is utilized, the need of a deblocking filter for low bit rates is finally evaluated to improve the statistical quality and visual appearance. </para>
Prostaglandin E1 inhibits collagenase gene expression in rabbit synoviocytes and human fibroblasts. (1992)

Cartilage breakdown, as seen in inflammatory and degenerative joint diseases, can be mediated by proteolytic enzymes, such as the metalloproteinase collagenase, the only enzyme able to digest collagen at neutral pH. In vitro collagenase gene expression can be stimulated by the phorbol ester tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate. We have investigated the effect of prostaglandin E1 (PGE1) on 12-O-tetradecanoyl-phorbol-13-acetate-stimulated collagenase mRNA levels in the rabbit synoviocyte cell line HIG-82. PGE1, but not PGE2 or PGF2 alpha, was able to selectively reduce collagenase mRNA levels in a dose-dependent fashion. PGE1 markedly increased intracellular levels of cAMP, while PGE2 and PGF2 alpha had little or no effect on cAMP production in the HIG-82 synoviocytes. Agents known to increase intracellular cAMP levels, such as the adenyl cyclase activator forskolin and the phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine (IBMX), mimicked the effect of PGE1, on collagenase mRNA levels. PGE1, forskolin, and IBMX also decreased collagenase mRNA levels in human skin fibroblasts, demonstrating that this observation was not unique to the HIG-82 cell line. Transient transfection experiments carried out in HIG-82 cells using a 1.2-kilobase portion of the 5'-flanking region of the human collagenase gene linked to the reporter gene luciferase demonstrated that PGE1, forskolin, and IBMX exert their inhibitory effect on the promoter region of the collagenase gene.
