Dynamic Reconfigurable Hub as a Stationary Node in a Hybrid Sensor Network (2013)

Sensor network systems are being expanded with the development of technology for the design of a low-power chips and for operating sensor networks. However, it is difficult to modify or change an application for a stationary sensor node after installation in the field. Furthermore, there is a limit to installation after developing and testing a new sensor node if it needs to reconfigure the software and hardware of the existing sensor node. Therefore, not only is software reconfiguration needed but also dynamic hardware reconfiguration for various changes in requirements, such as sensor type, communication bandwidth, quality of service, or reduced power consumption depending on the changing environment and requirements of users. This paper proposes a specially designed stationary node called a SMART (system management architecture for reconfigurable technology) node, which is capable of dynamic reconfiguration of the various sensing functions or communication protocols. The SMART node can provide suitable service and change the communication protocol according to various surroundings and user requirements.
Comparison of Cell-Based and Topology-Control-Based Energy Conservation in Wireless Sensor Networks (2005)

In this chapter we compare the effectiveness of two popular energy conservation strategies, namely topology control protocols and cooperative cell-based approaches, to reduce the energy consumption, and thus extend the lifetime, of wireless sensor networks. To this end, we define a realistic (although necessarily idealized in some respects) and unified framework of investigation. Using this framework, we prove lower bounds on network lifetime for cell-based cooperative strategies with node densities that are known to be sufficient to ensure a connected network. We also perform a number of simulation experiments, under a traffic model specifically designed for sensor networks, to evaluate and compare cell-based approaches with topology control. This is the first attempt at a comprehensive understanding of the conditions under which one of these approaches outperforms the other. Indeed, our study reveals a number of properties of the techniques investigated, some of which are not at all obvious. As expected, cell-based cooperative approaches, which completely power down network interfaces of certain nodes for extended time periods, produce longer network lifetimes when node density is very high. However, even with moderately high density of nodes, cell-based approaches do not significantly extend lifetime when it is defined in terms of connectivity. While it is not surprising that cell-based approaches do not extend lifetime under low density conditions, we find that topology control techniques can significantly increase network lifetime under those conditions and, in fact, they substantially outperform cooperative approaches in this respect. More details on the precise findings can be found in Section 31.7.
Long-distance delivery route planning using a commercial electric vehicle including the arrangement of charging stations (2019)

The electric vehicle (EV) is a key factor in achieving building smart cities. In this study, long-distance delivery route planning is performed with a commercial EV including the arrangement of charging stations. The EV delivers some goods through the motorway for approximately 500-700 km. The EV is recharged at a service or parking area on the motorway by a recharging station if it cannot travel to the next one. Two delivery patterns are considered so that the EV is required to activities at a distribution point. The shortest path is calculated using the Dijkstra method. Three performance indexes are considered. The EV should recharge four or five times during its delivery activity, leading to a longer delivery time. However, carbon dioxide emissions and delivery activity costs are lower than gasoline vehicles. This result indicates that the EV is a powerful tool to achieve smart cities for long-distance delivery.
What Players do with the Ball: A Physically Constrained Interaction Modeling (2016)

Tracking the ball is critical for video-based analysis of team sports. However, it is difficult, especially in low-resolution images, due to the small size of the ball, its speed that creates motion blur, and its often being occluded by players. In this paper, we propose a generic and principled approach to modeling the interaction between the ball and the players while also imposing appropriate physical constraints on the ball's trajectory. We show that our approach, formulated in terms of a Mixed Integer Program, is more robust and more accurate than several state-of-the-art approaches on real-life volleyball, basketball, and soccer sequences.
Nutritional improvement of metabolic syndrome parameters in immature fructose-fed wild-type mice (2011)

The incidence of type 2 diabetes mellitus is on the increase worldwide, with both environmental and genetic factors implicated in its development. Diabetes is often preceded by metabolic syndrome (MS) and may develop in normal adults ingesting a high fructose diet. The effect of high fructose intake on the development of MS in children and adolescents is less clear. Our objective was to study the effects of a nutrient mixture and metformin (MET), a widely used oral diabetic medication, in modulating the physiological and biochemical parameters of a high fructose diet in immature mice. C57BL/6J wild‑type mice aged 7 weeks were administered 12% fructose in their water and MET in distilled water or a diabetic nutrient mix (DNM) over 7 weeks. DNM-fed mice showed a decrease in systolic blood pressure, total cholesterol and fructosamine compared to the fructose-fed only group (p<0.05). A discordant result was observed in the MET group, with a decrease in blood pressure but increases in total cholesterol and fructosamine (p<0.05). Serum glucose did not change significantly among the groups. Thus, symptoms of fructose-induced MS in young mice could be countered nutritionally. Additionally, MET may improve certain biochemical markers while worsening others.
Dose-Response Relationships for Vanilla Flavor and Sucrose in Skim Milk: Evidence of Synergy (2018)

Regarding cross-modality research, taste-aroma interaction is one of the most studied areas of research. Some studies have reported enhancement of sweetness by aroma, although it is unclear as to whether these effects actually occur: depending on the cognitive strategy employed by panelists, the effects may disappear, e.g., forcing panelists into an analytical strategy to control for dumping may not be able to reveal perceptual interactions. Previous studies have largely focused on solutions and model foods, and did not test stimuli or concentrations relevant to real food applications. This study addresses these gaps: 18 vanilla flavored sucrose milks, varying between 0–0.75% (w/w) two-fold vanilla, and 0–5% (w/w) sucrose, were rated by 108 panelists for liking and perceived sweetness, vanilla flavor, milk flavor, and thickness. Interactions between vanilla and sucrose were measured using deviations of real mixtures from additive models (via the isobole method), indicating vanilla aroma does enhance perceived sweetness. However, the sweetness enhancing effect of vanilla aroma was not as pronounced as that of sucrose on vanilla flavor. Measurable cross-modal interactions occur despite using an analytical cognitive strategy. More work is needed to investigate the influence of perceptual strategy on the degree of taste-aroma interactions in real foods.

Also, protective model of intellectual property can use in a protective work of digital contents, adaptive agent and system level protection on client machine. In conclusion, we describe the implementation of our model in Linux system.
Applicability of the slow crack growth test method for polyethylene gas pipes. Volume 2. Topical report (1992)

GRI has sponsored research at Battelle to develop the analytical capability to predict the performance and life expectancy of polyethylene (PE) gas pipe distribution systems. This report is the second volume in a series. The report examines the validity of a test method to characterize the slow crack growth (SCG) failure mechanism for use in such analyses and in materials selection to ensure acceptable long-term performance. This study shows that the slow crack growth test method presented provides a valid basis for characterizing the SCG resistance of PE gas pipe materials.
Berberine inhibits p53-dependent cell growth through induction of apoptosis of prostate cancer cells. (2009)

Berberine has anti-tumor properties in some cancer cells including prostate cancer, but the exact mechanisms and in vivo effects are unclear. We investigated anti-cancer activity of berberine in vitro and in vivo, and possible mechanisms in prostate cancer cells. Berberine treatment inhibited cell cancer growth in a concentration (0-50 microM) and time- (0-48 h) dependent manner without any growth inhibition in normal human prostate epithelial PWR-1E cells. However, the p53 expressing LNCaP cells were more susceptible against berberine than the p53 lacking PC-3 cells. The cell arrest in G0/G1 phase, apoptotic cell death and the expression of apoptotic cell death proteins Bax and caspase-3 was much higher in berberine-treated LNCaP cells than those in PC-3 cells. Exploration of p53 siRNA or pifithrin-alpha, a p53 inhibitor to the LNCaP cells, suppressed berberine-induced cell death and expression of apoptosis-related proteins. In xenograft in vivo studies, berberine reduced tumor weights and volumes accompanied with apoptotic cell death and increased expression of apoptotic cell death proteins, however, the extent of inhibitory effect was more significant in LNCaP cell-bearing mice. Therefore, these results indicated that berberine inhibited p53-dependent prostate cancer cell death.

A Rhabdomyoma Within a Multilocular Thymic Cyst in ap53-Null Mouse (2010)

A 9-month-old p53-null female mouse was found dead in its cage. At necropsy, a large thymic mass encompassed the heart. Microscopically, the mass was composed of numerous varying-sized cysts lined with simple squamous epithelial cells to columnar ciliated cells. Also present within this mass was a large aggregate of loosely arranged fusiform-shaped cells. These cells also were found in smaller numbers in the connective tissue surrounding the cysts. The larger aggregate of fusiform cells was positive for desmin and S-100 and negative for smooth muscle actin. Electron microscopy revealed well-formed Z lines and I bands of skeletal muscle phenotype. A diagnosis of rhabdomyoma within a congenital multilocular thymic cyst was made. The thymus contains a small population of myoid cells, which should be taken in consideration when evaluating thymic tumors.

Hydrogen as a local probe: Diffusion and short-range order inTi1−yVyalloys (1989)

Diffusion coefficients of hydrogen have been measured in disordered ${\mathrm{Ti}}_{1\mathrm{\ensuremath{-}}\mathrm{y}}$${\mathrm{V}}_{\mathrm{y}}$ alloys, as a function of temperature, hydrogen concentration, and alloy composition. Diffusion and electron microprobe analysis data indicate the existence of short-range order (clustering) in ${\mathrm{Ti}}_{1\mathrm{\ensuremath{-}}\mathrm{y}}$${\mathrm{V}}_{\mathrm{y}}$ alloys, as observed before in the related ${\mathrm{Ti}}_{1\mathrm{\ensuremath{-}}\mathrm{y}}$${\mathrm{Nb}}_{\mathrm{y}}$ alloy system by diffusive x-ray scattering. The diffusion data are analyzed by means of a model, incorporating site-dependent activation energies, effective hydrogen-hydrogen interactions, and selective-blocking factors, generalized for alloys with short-range order. Site energies are calculated by means of the embedded-cluster model, assuming the energy of the hydrogen atoms to be predominantly determined by the nearest-neighbor metal atoms. An approximate relation between the short-range-order parameter \ensuremath{\sigma} and the site distribution is established. For \ensuremath{\sigma}&lt;0 a ``chain'' model and for \ensuremath{\sigma}&gt;0 a ``cluster'' model are in good agreement with Monte Carlo calculations. Using the short-range-order parameter \ensuremath{\sigma} as the only fit parameter, the short-range order in ${\mathrm{Ti}}_{1\mathrm{\ensuremath{-}}\mathrm{y}}$${\mathrm{V}}_{\mathrm{y}}$ alloys is determined from diffusion and solubility data. The quantitative determination of the short-range order in ${\mathrm{Ti}}_{1\mathrm{\ensuremath{-}}\mathrm{y}}$${\mathrm{V}}_{\mathrm{y}}$ alloys and ${\mathrm{Mo}}_{1\mathrm{\ensuremath{-}}\mathrm{y}}$${\mathrm{Ti}}_{\mathrm{y}}$ alloys from diffusion and solubility data, which are in excellent agreement with diffusive x-ray scattering data, shows that hydrogen can be a valuable tool to investigate the microscopic structure of concentrated disordered alloys.
Improved Performance of Ultrafiltration Membranes after Surface Modification (2020)

Commercial polyethersulfone (PES) membrane was modified and evaluated for the removal of metal ions from an aqueous solution. Modifications were carried out by a radical polymerization technique, using acrylic acid as monomer. The grafting polymerization on the membrane was developed in an aqueous medium at 60°C. Two molar initiator/monomer (3 and 7%) ratios were used to study PES-grafted-polyaceylic acid membranes. Both unmodified and modified membranes were analyzed by attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy, scanning electron microscopy (SEM), and atomic force microscopy (AFM) in order to look into their morphologies. In addition, contact angle measurements were used for membrane hydrophilicity. The ATR-FTIR spectra, SEM and AFM images confirmed that the modification on the PES membrane surface was carried out by grafting polymer of acrylic acid monomers. The results obtained show that acrylic acid may be used for the preparation of a selective membrane functionalized with carboxylic groups. Water permeability was evaluated by varying the feed pressures (4–10 bars). The flux water of unmodified membrane decreased from 10 to 6 L/h m2 bar for modified membranes. The rejections of sodium chloride, copper chloride, and aluminum chloride were also studied for each sample. Among the metal ions tested, thevmaximum removal was reported for aluminium for grafted membrane at 7% ratio. The rejection values for grafted membranes (3 and 7%) were higher than those obtained for unmodified membranes and increased with the grafting rate.
Molecular beam epitaxy and metalorganic chemical vapor deposition growth of epitaxial CdTe on (100) GaAs/Si and (111) GaAs/Si substrates (1988)

Epitaxial CdTe has been grown on both (100)GaAs/Si and (111)GaAs/Si substrates. A combination of molecular beam epitaxy (MBE) and metalorganic chemical vapor deposition (MOCVD) has been employed for the first time to achieve this growth: the GaAs layers are grown on Si substrates by MBE and the CdTe film is subsequently deposited on GaAs/Si by MOCVD. The grown layers have been characterized by x-ray diffraction, scanning electron microscopy, and photoluminescence.

Cytosolic delivery of macromolecules: I. Synthesis and characterization of pH-sensitive acyloxyalkylimidazoles (2021)

A series of 1-(acyloxyalkyl)imidazoles (AAI) were synthesized by nucleophilic substitution of chloroalkyl esters of fatty acids with imidazole. The former was prepared from fatty acid chloride and an aldehyde. When incorporated into liposomes, these lipids show an apparent pK(a) value ranging from 5.12 for 1-(palmitoyloxymethyl)imidazole (PMI) to 5.29 for 1-[(alpha-myristoyloxy)ethyl]imidazole (alpha-MEI) as determined by a fluorescence assay. When the imidazole moiety was protonated, the lipids were surface-active, as demonstrated by hemolytic activity towards red blood cells. As expected, AAI were hydrolyzed in serum as well as in cell homogenate. They were significantly less toxic than biochemically stable N-dodecylimidazole (NDI) towards Chinese hamster ovary (CHO) and RAW 264.7 (RAW) cells as determined by MTT assay. When fed to RAW cells, fluorescein-labeled oligonucleotides encapsulated in liposomes containing 20 mol% 1-(stearoyloxymethyl)imidazole (SMI) resulted in punctate as well as partially diffuse fluorescence. In a functional assay involving down-regulation of luciferase in CV-1 cells, neutral liposomes containing imidazole lipids showed suboptimal delivery of antisense phosphorothioate oligomers. Taken together, the results suggest that AAI are of potential use in developing nontoxic, pH-sensitive liposomes. However, these liposomal formulations need to be optimized to achieve higher concentrations of pH-sensitive detergents within the endosome to facilitate efficient cytosolic release of liposome-entrapped contents.

Faculty Opinions recommendation of Selective rab11 transport and the intrinsic regenerative ability of CNS axons. (2019)

Neurons lose intrinsic axon regenerative ability with maturation, but the mechanism remains unclear. Using an in-vitro laser axotomy model, we show a progressive decline in the ability of cut CNS axons to form a new growth cone and then elongate. Failure of regeneration was associated with increased retraction after axotomy. Transportation into axons becomes selective with maturation; we hypothesized that selective exclusion of molecules needed for growth may contribute to regeneration decline. With neuronal maturity rab11 vesicles (which carry many molecules involved in axon growth) became selectively targeted to the somatodendritic compartment and excluded from axons by predominant retrograde transport However, on overexpression rab11 was mistrafficked into proximal axons, and these axons showed less retraction and enhanced regeneration after axotomy. These results suggest that the decline of intrinsic axon regenerative ability is associated with selective exclusion of key molecules, and that manipulation of transport can enhance regeneration.
Induction of Gamma Interferon and Nitric Oxide by Truncated Pneumolysin That Lacks Pore-Forming Activity (2002)

Pneumolysin (PLY), an important virulence factor of Streptococcus pneumoniae, is known to exert various effects on the host immune cells, including cytokine induction, in addition to its known cytolytic activity as a member of the thiol-activated cytolysins. It is of interest to determine whether cytolytic activity is involved in triggering the cytokine production. In this study, we constructed full-length recombinant PLY and noncytolytic truncated PLYs with C-terminal deletions to examine the response of spleen cells to these PLY preparations. When cytolytic activity was blocked by treatment with cholesterol, full-length PLY was capable of inducing gamma interferon (IFN-gamma) production. Truncated PLYs that originally exhibited no cytolytic activity were also active in IFN-gamma induction. Therefore, the IFN-gamma-inducing ability of PLY appeared to be independent of the cytolytic activity. Furthermore, IFN-gamma-inducing preparations were also capable of inducing nitric oxide synthase expression and nitric oxide (NO) production, and the addition of neutralizing antibody to IFN-gamma abolished the NO production. These results clearly demonstrated that PLY is capable of inducing IFN-gamma production in spleen cells by a mechanism different from pore formation and that the induced IFN-gamma stimulates NO production. These findings were discussed with reference to the contribution of PLY to the virulence of S. pneumoniae in vivo.
