Mutual Verifiable Provable Data Auditing in Public Cloud Storage (2015)

Cloud storage is now a hot research topic in information technology. In cloud storage, date security properties such as data confidentiality, integrity and availability become more and more important in many commercial applications. Recently, many provable data possession (PDP) schemes are proposed to protect data integrity. In some cases, it has to delegate the remote data possession checking task to some proxy. However, these PDP schemes are not secure since the proxy stores some state information in cloud storage servers. Hence, in this paper, we propose an efficient mutual verifiable provable data possession scheme, which utilizes Diffie-Hellman shared key to construct the homomorphic authenticator. In particular, the verifier in our scheme is stateless and independent of the cloud storage service. It is worth noting that the presented scheme is very efficient compared with the previous PDP schemes, since the bilinear operation is not required.
Heterogeneous resource management for dynamic real-time systems (2002)

Dynamic real-time systems face many resource management problems. This paper addresses the following problems: (1) dynamic resource allocation to provide QoS objectives, (2) heterogeneous resources, and (3) non-intrusive accurate monitoring of QoS, resource availability and resource needs. This paper describes the techniques of a resource manager handling the above problems to support the QoS of dynamic distributed real-time systems. The contributions of this paper to solve these problems are as follows: unification of dynamic resource requirements among heterogeneous hosts, control of resources in heterogeneous environments, feasibility analysis and dynamic load balancing/sharing. Our heuristic allocation scheme not only allows higher workloads than the random, round-robin and least-load schemes by 257%, 142% and 36.4%, respectively, but it also improves the QoS compared to those schemes by 38.6%, 28.5% and 31.6%, respectively.
Discriminative random fields: a discriminative framework for contextual interaction in classification (2003)

In this work we present discriminative random fields (DRFs), a discriminative framework for the classification of image regions by incorporating neighborhood interactions in the labels as well as the observed data. The discriminative random fields offer several advantages over the conventional Markov random field (MRF) framework. First, the DRFs allow to relax the strong assumption of conditional independence of the observed data generally used in the MRF framework for tractability. This assumption is too restrictive for a large number of applications in vision. Second, the DRFs derive their classification power by exploiting the probabilistic discriminative models instead of the generative models used in the MRF framework. Finally, all the parameters in the DRF model are estimated simultaneously from the training data unlike the MRF framework where likelihood parameters are usually learned separately from the field parameters. We illustrate the advantages of the DRFs over the MRF framework in an application of man-made structure detection in natural images taken from the Corel database.
Determinants of 5-Lipoxygenase Nuclear Localization Using Green Fluorescent Protein/5-Lipoxygenase Fusion Proteins (1998)

5-Lipoxygenase catalyzes the first two steps in the biosynthesis of leukotrienes, potent extracellular mediators of inflammation and allergic disorders. The unanticipated observation of 5-lipoxygenase in the nucleus of some cell types including bone marrow-derived mast cells (Chen, X. S., Naumann, T. A., Kurre, U., Jenkins, N. A., Copeland, N. G., and Funk, C. D. (1995) J. Biol. Chem. 270, 17993-17999) has raised speculation about intranuclear actions of leukotrienes or the enzyme itself. To explore the entry of 5-lipoxygenase into the nucleus we have transfected various cell types with expression vectors encoding native 5-lipoxygenase and green fluorescent protein/5-lipoxygenase (GFP-5LO) fusion proteins. 5-Lipoxygenase and green fluorescent protein/5-lipoxygenase co-localized with the nuclear DNA stain Hoechst 33258 in each cell type. The three main basic regions of 5-lipoxygenase were incapable of acting as "classical" nuclear localization signal sequences. Mutations that abolished enzyme activity/non-heme iron resulted in proteins that would no longer enter the nucleus. An NH2-terminal 5-lipoxygenase fragment of 80 residues was sufficient for directing nuclear localization of green fluorescent protein but not cytosolic pyruvate kinase. The combined data suggest that 5-lipoxygenase enters the nucleus not by a classical nuclear localization signal but by a non-conventional signal located in the predicted beta-barrel domain that may be masked by structural alterations.
[Sanitary service of West Special Military District on the eve and in the first days of the Great Patriotic War of 1941-1945]. (2011)

This article evaluates military and political situation in the world and operational-strategic environment on the West Theater of operations on the eve of the Great Patriotic War (1941-1945). We analyze structure and overall condition of sanitary service of West Special Military District of the Workers and Peasants Red Army and causes of failure of mobilization, organization and deployment of military units and establishments from the beginning of aggression of Fascist Germany to the Soviet Union.
Organic field-effect transistors with polarizable gate insulators (2002)

A quasi-stable threshold voltage (Vt) shift is imparted onto field-effect transistors (FETs) with organic semiconductors and polymer dielectrics. Adjustment of Vt from accumulation mode to zero or depletion mode is demonstrated for both p-channel and n-channel FETs, and is accomplished by applying a depletion voltage to the gate prior to device operation. Hydrophobic dielectrics and dopant-resistant semiconductors were advantageous. A pixel circuit that utilizes this nonvolatile memory element is proposed.
Fully depleted 20-nm SOI CMOSFETs with W-clad gate/source/drain layers (2001)

Fully-depleted 20-nm SOI complementary metal-oxide-semiconductor field effect transistors (CMOSFETs) were successfully fabricated without a raised source/drain (S/D) structure, instead using low-temperature selective tungsten CVD (SWCVD) technology that can reduce the S/D series resistance. The thickness of the residual SOI layer under the W-clad layer in the S/D region was 6 nm for an nMOSFET and 9 nm for a pMOSFET. For 0.15-/spl mu/m-gate CMOSFETs, the subthreshold swings were 70 and 75 mV/dec for the nMOSFET and pMOSFET, respectively. The effectiveness of SWCVD technology when applied to ultrathin SOI devices was confirmed by small Si consumption and good continuity between the W and SOI layers. We expect that the S/D series resistance can be reduced to less than 1 k/spl Omega/-/spl mu/m by optimizing the S/D implantation conditions.

Structural requirements for enzymatic formation of threonylcarbamoyladenosine (t6A) in tRNA: an in vivo study with Xenopus laevis oocytes. (1998)

We have investigated the specificity of the eukaryotic enzymatic machinery that transforms adenosine at position 37 (3' adjacent to anticodon) of several tRNAs into threonylcarbamoyladenosine (t6A37). To this end, 28 variants of yeast initiator tRNAMet and yeast tRNAVal, devoid of modified nucleotide, were produced by in vitro transcription with T7 polymerase of the corresponding synthetic tRNA genes and microinjected into the cytoplasm of Xenopus laevis oocytes. Threonylcarbamoyl incorporation was analyzed in tRNA transcripts mutated in the anticodon loop by substitution, deletion, or Insertion of nucleotides, or in the overall 3D structure of the tRNA by altering critical tertiary interactions. Specifically, we tested the effects of altering ribonucleotides in the anticodon loop, changes of the loop size, perturbations of the overall tRNA 3D structure due to mutations disruptive of the tertiary base pairs, and truncated tRNAs. The results indicate that, in addition to the targeted A37, only U36 was absolutely required. However, A38 in the anticodon loop considerably facilitates the quantitative conversion of A37 into t6A37 catalyzed by the enzymes present in X. laevis. The anticodon positions 34 and 35 were absolutely "neutral" and can accept any of the four canonical nucleotides A, U, C, or G. The anticodon loop size may vary from six to eight nucleotides, and the anticodon stem may have one mismatch pair of the type AxC or GxU at location 30-40 without affecting the efficiency of t6A37 formation and still t6A37 is efficiently formed. Although threonylcarbamoylation of A37 occurred with tRNA having limited perturbations of 3D structure, the overall L-shaped architecture of the tRNA substrate was required for efficient enzymatic conversion of A37 to t6A37. These results favor the idea that unique enzymatic machinery located in the oocyte cytoplasm catalyzes the formation of t6A37 in all U36A37-containing tRNAs (anticodon NNU). Microinjection of the yeast tRNAMeti into the cytoplasm of X. laevis oocytes also revealed the enzymatic activities for several other nucleotide modifications, respectively m1Gg, m2G10, m(2)2G26, m7G46, D47, m5C48/49, and m1A58.
Dependence of composition fluctuation on indium content in InGaN/GaN multiple quantum wells (2000)

The information on the variations of indium composition, aggregation size, and quantum-well width is crucially important for understanding the optical properties and, hence, fabricating efficient light-emitting devices. Our results showed that spinodal decomposition could occur in InGaN/GaN multiple quantum wells with indium content in the range of 15%–25% (grown with metal–organic chemical-vapor deposition). A lower nominal indium content led to a better confinement of indium-rich clusters within InGaN quantum wells. The InGaN/GaN interfaces became more diffusive, and indium-rich aggregates extended into GaN barriers with increasing indium content. It was also observed that indium-rich precipitates with diameter ranging from 5 to 12 nm preferred aggregating near V-shaped defects.
Grouping wireless Picocells to build a local area wireless infrastructure (2000)

Diese Dissertation stellt eine systematische Untersuchung vor von Lösungen für effizienten Handover in einer drahtlosen, LAN-basierten Kommunikationsumgebung innerhalb von Gebäuden. Die gewählte Umgebung besteht aus mehreren drahtlosen Zellen die mittels einer zweiten Netzwerkinfrastruktur verbunden werden Die Funkzellen werden dadurch zu einer grösseren Einheit zusammengebunden, die den gängigen Dimensionen eines lokalen Netzes entsprechen. Diese Architektur wurde gewählt da die Reichweite zukünftiger Funkzellen sehr klein sein wird (~10 Meter) was zu sehr häufigem Handover führen wird. Um die aufwändigen Handover auf der Netzwerkschicht bei dieser hohen Rate zu vermeiden wird ein einzelnes lokales Netz bestehend aus mehreren Zellen aufgebaut, was ein Mobilitätsmanagement im lokalen Rahmen erlaubt und das dadurch effizienter und schneller ist als Lösungen auf Netzwerkschicht. Hinsichtlich der steigenden Nachfrage nach Unterstützung für Echtzeitkommunikation in Kommunikationsnetzen, werden die offenen Fragen und diesbezüglichen Eigenschaften in solch einem System weitergehend diskutiert und betrachtet. Die Dissertation untersucht den Raum für hier anwendbare Strategien und identifiziert die Grundmechanismen, die ihnen zugrunde liegen. Für die Lösungen werden Spezifikationen erarbeitet. Die spezifizierten Schemata wurden mittels simulativer Verfahren bezüglich ihrer Leistung verglichen und bewertet im Hinblick auf ihre unterschiedlichen Funktionalitäten. Die Dissertation schliesst mit abschliessenden Bemerkungen ab.
Nanoscale conductive niobium oxides made through low temperature phase transformation for electrocatalyst support (2014)

We report an effective approach to synthesize nanoscale Nb2O5 coated on carbon nanotubes (CNTs) and transform it at low temperatures to the conductive form of NbO2. The latter, when used as a Pt electrocatalyst support, shows significant enhancement in catalyst activity and durability in the oxygen reduction reaction (ORR). Direct phase transformation of Nb2O5 to NbO2 often requires temperatures above 1000 °C. Here we show that this can be achieved at a much lower temperature (e.g. 700 °C) if the niobium oxide is first activated with carbon. Low temperature processing allows retaining nanostructures of the oxide without sintering, keeping its high surface areas needed for being a catalyst support. We further show that Pt supported on the conductive oxides on CNTs has two times higher mass activity for the ORR than on bare CNTs. The electrochemical stability of Pt was also outstanding, with only ca. 5% loss in electrochemical surface areas and insignificant reduction in half-wave potential in ORR after 5000 potential cycles.
Inactivation of infectious bursal disease virus by binary ethylenimine and formalin (2006)

In this experiment conducted to study the inactivation dynamics of infectious bursal disease virus (IBDV) by binary ethylenimine (BEI) in comparison with formalin, IBDV was isolated from the bursa of infected chickens and its confirmation was done by agar gel precipitation test. Viral suspensions were subjected to inactivation with BEI and formalin for pre-set time intervals. BEI was employed at concentrations of 0.001 and 0.002 mol/L while formalin was used at 0.1% and 0.2%. Sampling was done at 6, 12, 24, 36 and 48 h of incubation and samples were tested for their inactivation status in 9-day-old embryonated eggs and 3-week-old broiler chickens. IBDV was completely inactivated by 0.001 and 0.002 mol/L BEI after 36 h of incubation at 37 degrees C, whereas formalin at 0.1% and 0.2% concentrations inactivated IBDV in 24 h.
<i>In Vivo</i> Muscle Force–Length Behavior During Steady-Speed Hopping in Tammar Wallabies (1998)

Moderate to large macropodids can increase their speed while hopping with little or no increase in energy expenditure. This has been interpreted by some workers as resulting from elastic energy savings in their hindlimb tendons. For this to occur, the muscle fibers must transmit force to their tendons with little or no length change. To test whether this is the case, we made in vivo measurements of muscle fiber length change and tendon force in the lateral gastrocnemius (LG) and plantaris (PL) muscles of tammar wallabies Macropus eugenii as they hopped at different speeds on a treadmill. Muscle fiber length changes were less than +/-0.5 mm in the plantaris and +/-2.2 mm in the lateral gastrocnemius, representing less than 2 % of total fiber length in the plantaris and less than 6 % in the lateral gastrocnemius, with respect to resting length. The length changes of the plantaris fibers suggest that this occurred by means of elastic extension of attached cross-bridges. Much of the length change in the lateral gastrocnemius fibers occurred at low force early in the stance phase, with generally isometric behavior at higher forces. Fiber length changes did not vary significantly with increased hopping speed in either muscle (P>0.05), despite a 1. 6-fold increase in muscle-tendon force between speeds of 2.5 and 6.0 m s-1. Length changes of the PL fibers were only 7+/-4 % and of the LG fibers 34+/-12 % (mean +/- S.D., N=170) of the stretch calculated for their tendons, resulting in little net work by either muscle (plantaris 0.01+/-0.03 J; gastrocnemius -0.04+/-0.30 J; mean +/- s.d. ). In contrast, elastic strain energy stored in the tendons increased with increasing speed and averaged 20-fold greater than the shortening work performed by the two muscles. These results show that an increasing amount of strain energy stored within the hindlimb tendons is usefully recovered at faster steady hopping speeds, without being dissipated by increased stretch of the muscles' fibers. This finding supports the view that tendon elastic saving of energy is an important mechanism by which this species is able to hop at faster speeds with little or no increase in metabolic energy expenditure.
Electrophysiological effects of high cocaine concentrations on intact canine heart. Evidence for modulation by both heart rate and autonomic nervous system. (1993)

We conclude that high plasma levels of cocaine, similar to those reported in autopsy reports following fatal cocaine overdose in humans, produce significant rate-dependent conduction slowing effects on atrial, atrioventricular, and ventricular conduction in the in situ heart. These rate-dependent effects are intensified following autonomic blockade.
A computational grammar of discourse-neutral prosodic phrasing in English (1990)

We describe an experimental text-to-speech system that uses information about syntactic constituency, adjacency to a verb, and constituent length to determine prosodic phrasing for synthetic speech. A central goal of our work has been to characterize neutral phrasing, i.e. sentence-level phrasing patterns that are independent of discourse semantics. Our account builds on Bachenko et al. (1986), but differs in its treatment of clausal structure and predicate-argument relations. Results so far indicate that the current system performs well when measured against a corpus of judgments of prosodic phrasing.
Microlens reflector for out-of-plane optical coupling of a waveguide to a buried silicon photodiode (2004)

A photoresist microlens is shown to be an extremely efficient reflective element for out-of-plane coupling of light from a negative epoxy-based photoresist (SU8) optical waveguide into a buried silicon pn photodetector. Experimentally determined coupling efficiencies are given for integrated waveguide∕photodetector and waveguide∕microlens∕photodetector structures. The highest measured coupling efficiency in a structure with a 40μm diameter, 13μm high microlens is about 74%, versus an average of about 11% in structures without a microlens. The measured microlens-mediated coupling efficiency is in satisfactory agreement with a simple ray tracing simulation that provides a calculated value of 77.5% for the coupling efficiency.
PD detection and localisation by acousticmeasurements in anoil-filled transformer (2000)

A pattern recognition method for localisation of the partial discharge (PD) site in an oil-filled transformer by acoustic measurements is presented. By dividing the transformer into a number of 20 × 20 × 20 mm3 sub-modules, the PD site is localised by comparing the spatial distance of each sub-module to the acoustic sensors. The numerical cases indicate that the proposed method is general and practical, while avoiding some drawbacks in current algorithms. Moreover, the method improves the accuracy of localisation substantially when compared with the conventional localisation method.
Temperature‐dependent Raman scattering studies of the geometrically frustrated pyrochlores Dy<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub>, Gd<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> and Er<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> (2008)

Abstract The temperature‐dependent Raman studies of A 2 Ti 2 O 7 (A = Dy, Er, Gd) were performed on single crystals and polycrystalline samples in the 4.2–295 K temperature range. The Raman spectra showed softening of the majority of phonon modes upon cooling in the whole temperature range studied and large decrease of linewidths. These changes have been analyzed in terms of strong third‐order phonon–phonon anharmonic interactions. Moreover, the 312 and 330 cm −1 modes of Er 2 Ti 2 O 7 (Gd 2 Ti 2 O 7 ) showed hardening upon cooling down to about 130 K (100 K) and then anomalous softening below this temperature. The observed anomalous behavior of the Raman modes indicates that some important changes occur in these materials at low temperatures. However, the origin of this behavior is still not clear.

Synthesis and properties of polyamides derived from systematically halogenated terephthalic acids with fluorine, chlorine, or bromine atoms (1988)

Abstract Aromatic polyamides were prepared from systematically halogenated terephthalic acids with hexamethylene diamine, piperazine, 4,4′‐diaminodiphenylether and p ‐phenylene diamine by interfacial or low temperature solution polycondensation. The halogenated terephthalic acids used have mono‐, di‐, or tetra‐substituted fluorine, chlorine, or bromine atoms on the benzene ring. The nonhalogenated terephthalic acid was also used for the comparison. The effects of halogen substitution on the benzene ring on the synthesis and some properties of polymers were examined. Reduced specific viscosity decreased in the order F > Cl > Br by halogen substitution. The incorporation of halogen substituents on the ring led to a decrease of crystallinity and fluoro‐substituents hindered the crystallization more strongly. The melting point ( T m ) decreased in the order F > Cl > Br by mono‐substitution, and Br > Cl > F by di‐and tetra‐substitution. The change of T m caused by the difference of the number of halogen substituents differed depending on the rigidity of polymer chains. The flame‐retardancy estimated by thermogravimetry, self‐ignition, and flash‐ignition test increased with increasing halogen content of the polymers. Solubility increased remarkably by halogen substitution. The peak temperature of tan δ decreased by halogen substitution. Some discussion was made on these effects of halogen substitution.

Efficient and High-Throughput Implementations of AES-GCM on FPGAs (2007)

This paper addresses efficient and high-throughput implementations of AES-GCM optimized for FPGAs. Two main components, the AES engine and the modular multiplication over GF(2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sup> ), are discussed and their complexities on FPGAs are shown. Instead of discussing the complexities by using AND and XOR gates as primitives, we present the complexity analysis directly based on FPGA primitives, e.g., Look-Up-Tables (LUTs). For the modular multiplier, the straightforward multiplication is used to get a speed-efficient design while the Karatsuba 's algorithm is used to get an area-efficient design. For the AES engine, the composite field approach is adopted and then inner-round pipelining technology is applied. The estimated resource consumption returned by the complexity analysis provides a good criterion to minimize the influence of technology mapping. By optimizing and balancing the critical delay of sub-components, two high performance GCM implementations are presented on Xilinx Virtex-4 devices.
