A Hybrid Cloud Approach for Secure Authorized Deduplication (2014)

Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. To better protect data security, this paper makes the first attempt to formally address the problem of authorized data deduplication. Different from traditional deduplication systems, the differential privileges of users are further considered in duplicate check besides the data itself. We also present several new deduplication constructions supporting authorized duplicate check in a hybrid cloud architecture. Security analysis demonstrates that our scheme is secure in terms of the definitions specified in the proposed security model. As a proof of concept, we implement a prototype of our proposed authorized duplicate check scheme and conduct testbed experiments using our prototype. We show that our proposed authorized duplicate check scheme incurs minimal overhead compared to normal operations.
Monitoring ageing CCVTs practical solutions with modern relays to avoid catastrophic failures (2007)

Ageing Coupling Capacitor Voltage Transformers (CCVTs) can pose safety problems and possibly restrain system operations. Catastrophic failure of a CCVT could start a widespread fault in the substation and/or endanger personnel working in a close proximity. The latter becomes a real danger when inspecting a suspicious CCVT or when Live Line work is being performed. CCVT monitoring becomes more and more important as the installed population of CCVTs ages with sporadic incidents of catastrophic failures alerting both field personnel and dispatching managers regarding safety and liability.
Chemotactic activity of neutrophil granulocytes in old people in health or with symptoms of infection. (1993)

Clinical observations point out that the inflammatory process follows a different course in old people as compared to young persons. In the studies on the mechanisms responsible for this difference the chemostatic activity of polymorphonuclear granulocytes was assessed in peripheral blood in healthy elderly persons and in people in the same age group with evidence of infections, mainly of bacterial origin. A decrease was demonstrated of the chemotactic activity of polymorphonuclears in healthy persons aged over 65 years, as compared to young people, and even a more pronounced reduction of this activity in old people with infections. The observed disturbances of the functions of phagocytic cells may be one of the causes of less effective antibacterial defense in the organism during the process of ageing.
Sensitivity of the cervical transformation zone to estrogen-induced squamous carcinogenesis. (2000)

Regions where one type of epithelium replaces another (metaplasia) have a predilection for cancer formation. Environmental factors are closely linked to metaplastic carcinogenesis. In particular, cervical cancers associated with human papillomavirus (HPV) infection develop primarily at the transformation zone, a region where metaplastic squamous cells are detected in otherwise columnar epithelial-lined endocervical glands. Previously, we reported estrogen-induced multistage vaginal and cervical carcinogenesis in transgenic mice expressing HPV16 oncogenes in basal squamous epithelial cells. In the present study to investigate the threshold neoplastic response to exogenous estrogen, we treated groups of transgenic mice with lower hormone doses. A 5-fold reduction in estrogen dose induced squamous carcinogenesis solely at the cervical transformation zone compared with other reproductive tract sites. Further study delineated stages of transformation zone carcinogenesis, including formation of hyperplastic lower uterine glands and emergence of multiple foci of squamous metaplasia from individual stem-like glandular reserve cells, followed by neoplastic progression of metaplasia to dysplasia and squamous cancer. We propose that a combination of low-dose estrogen and low-level HPV oncogene expression biases transformation zone glandular reserve cells toward squamous rather than columnar epithelial fate decisions. Synergistic activation of proliferation by viral oncoprotein cell cycle dysregulation and estrogen receptor signaling, together with altered paracrine stromal-epithelial interactions, may conspire to support and promote neoplastic progression and cancer formation.

Remodeling of sugar chain structures of human interferon-  (2000)

Natural human interferon (IFN)-gamma has mainly biantennary complex-type sugar chains and scarcely has multiantennary structures. We attempted to remodel the sugar chain structures using IFN-gamma as a model glycoprotein. To obtain the branching glycoforms of IFN-gamma, we introduced the genes for GnT-IV (UDP-N-acetylglucosamine:alpha-1,3-D-mannoside beta-1, 4-N-acetylglucosaminyltransferase) and/or GnT-V (UDP-N-acetylglucosamine:alpha-1,6-D-mannoside beta-1, 6-N-acetylglucosaminyltransferase) into Chinese hamster ovary (CHO) cells producing human IFN-gamma. The parental CHO cells produced IFN-gamma with biantennary sugar chains mainly. When the GnT-IV activity was increased, triantennary sugar chains with a branch produced by GnT-IV increased up to 66.9% of the total sugar chains. When the GnT-V activity was increased, triantennary sugar chains with a corresponding branch increased up to 55.7% of the total sugar chains. When the GnT-IV and -V activities were increased at a time, tetraantennary sugar chains increased up to 56.2% of the total sugar chains. The proportion of these multiantennary sugar chains corresponded to the intracellular activities of GnT-IV and -V. What is more, lectin blot and flow cytometric analysis indicated that the multi-branch structure of the sugar chains was increased not only on IFN-gamma, one of the secretory glycoproteins, but also on almost CHO cellular proteins by introducing either or both of the GnT genes. The results suggest that the branching structure of sugar chains of glycoproteins could be controlled by cellular GnT-IV and GnT-V activities. This technology can produce glycoforms out of natural occurrence, which should enlarge the potency of glycoprotein therapeutics.
A 100 MHz Hybrid Supply Modulator With Ripple-Current-Based PWM Control (2016)

This paper presents a 100 MHz hybrid supply modulator (HSM) with ripple-current-based pulse width modulation (PWM) control. By sensing the ripple current, a ripple current sensor (RCS) is able to overcome the bandwidth limitation of an absolute current sensor. By leveraging the RCS, we propose a large-signal PWM control method for HSMs. This method has an intrinsically fast switching loop, and thus eliminates the need for the feed-forward path used in many previous designs. The possibility of generating high-order harmonics in PWM-controlled HSMs is pointed out for the first time, and design recommendations to avoid them are presented. A very-high-frequency triangular wave generator that is robust to both process-voltage-temperature (PVT) variations and device mismatches is proposed. A proof-of-concept prototype was fabricated in CMOS 130 nm technology. Switching at 100 MHz, this HSM is able to track a 0.8 V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pp</sub> sinusoidal waveform up to 13 MHz with high fidelity. It achieves a peak efficiency of 88.2% at the maximum output power of 23 dBm. To the best of our knowledge, this is the first PWM-controlled HSM that is able to operate at 100 MHz.
Comparison of AVO indicators: A modeling study (1994)

Abstract A worldwide collection of 25 sets of velocity and density measurements from adjacent shales, brine sands, and gas sands was acquired with full-waveform sonic, dipole sonic, and conventional well logging devices and/or in the laboratory. These data provide theoretical shale over brine-sand and shale over gassand P-wave and S-wave normal-incidence reflection coefficients (RP and RS), AVO intercepts (A), AVO gradients (B), the AVO indicators RP — RS (reflection coefficient difference), and A * B (AVO product). The reflection coefficient difference is found to be a more universal indicator than the AVO product in clastic stratigraphic intervals. For shale over brine-sand reflections, the average RP — RS tends to be near zero and relatively invariant with depth. Irrespective of gas-sand impedance, RP — RS is always negative for shale over reservoir quality gas-sand reflections and more negative than for the corresponding brine-sand reflections. In comparison, the AVO product may be positive, near zero, or negative for gas-sands depending on the impedance contrast with the overlying shale. These measurements also verily that RP — RS is well approximated by a simple linear combination of A and B.
One-Pot Synthesis of 3,5-Disubstituted and Polysubstituted Phenols from Acyclic Precursors (2015)

A new strategy for the synthesis of 3,5-disubstituted phenols is established through one-pot Robinson annulation of α,β-unsaturated ketones with α-fluoro-β-ketoesters followed by in situ dehydrofluorination and tautomerization. This method has been extended to the synthesis of polysubstituted phenols and applied in the preparation of biologically active compounds.

Seawater Magnetohydrodynamics Power Generator / Hydrogen Generator (2010)

A seawater magnetohydrodynamics (MHD) power generator / hydrogen generator is expected to become popular with the development of superconducting technology because of low loss and high efficiency. We have designed a new helical-type seawater MHD generator using a solenoid superconducting magnet, by considering the experimental results for a helical-type MHD ship. The experimental and computational results for the helical-type generator including the results of a recent study on hydraulic characteristics are discussed.
Third-order nonlinear optical properties of thin films of poly(<i>p</i>-phenylene benzobisthiazole) and its molecular composites with polyamides (1991)

The nonresonant third-order nonlinear optical properties of thin films of poly(p-phenylene benzobisthiazole) (PBZT) and PBZT/nylon 66 and PBZT/poly(trimethylhexamethylene terephthalmide) (PTMHT) molecular composites have been investigated using picosecond third-harmonic generation at 1.9 μm. The measured χ(3)(−3ω,ω,ω,ω) for the pure PBZT was (1.37±0.27)×10−11 esu. The χ(3) of PBZT/nylon composites showed a linear dependence on composition. In contrast, the χ(3) of PBZT/PTMHT molecular composites significantly deviated from this linear dependence, showing enhanced values. No in-plane anisotropy in any of the films was detected. The optical damage threshold of PBZT was measured to be ≳50 GW/cm2 for 30 ps pulses at 1.9 μm.
Neurovascular and molecular mechanisms in migraine headaches. (1993)

This chapter reviews the evidence that challenges traditional and unproven notions which perpetuate the singular importance of constriction and dilation to the genesis of migraine pain. New data in experimental laboratory models suggest that migraine headache may develop primarily from metabolic/neurophysiological events (as yet unidentified) within the cortical mantle, or from a disturbance in those regions of brain which closely approximate the distribution of trigeminovascular fibers innervating meningeal blood vessels. Accordingly, this chapter will review the consequences of trigeminovascular activation to pain and meningeal inflammation, and will summarize emerging molecular and pharmacological data suggesting that ergot alkaloids and sumatriptan alleviate pain primarily via activation of pre-junctional 5-HT1 heteroreceptors residing on primary afferent trigeminovascular fibers.

Kallikrein 4 is a Predominantly Nuclear Protein and Is Overexpressed in Prostate Cancer (2004)

Kallikreins (KLKs) are highly conserved serine proteases that play key roles in a variety of physiological and pathological processes. KLKs are secreted proteins that have extracellular substrates and function. For example, prostate-specific antigen (or KLK3) is a secreted protein that is widely used as a diagnostic marker for prostate cancer. KLK4 is a recently identified member of the kallikrein family that is regulated by androgens and is highly specific to prostate for expression. Here, we show that the gene product of KLK4, hK4, is the first member of the KLK family that is intracellularly localized. We provide strong evidence that the previously assigned first exon that was predicted to code for a signal peptide that would target hK4 for secretion is not part of the physiologically relevant form of KLK4 mRNA. In addition to detailed mapping of the KLK4 mRNA 5' end by RT-PCR, this conclusion is supported by predominantly nuclear localization of the hK4 protein in the cell, documented by both immunofluorescence and cell fractionation experiments. Furthermore, in addition to androgens, hK4 expression is regulated by estrogen and progesterone in prostate cancer cells. Finally, in situ hybridization on normal and hyperplastic prostate samples in tissue microarrays indicate that KLK4 is predominantly expressed in the basal cells of the normal prostate gland and overexpressed in prostate cancer. These data suggest that KLK4 has a unique structure and function compared with other members of the KLK family and may have a role in the biology and characterization of prostate cancer.
Many-body interaction effects in doped and undoped graphene: Fermi liquid versus non-Fermi liquid (2007)

We consider theoretically the electron-electron interaction induced many-body effects in undoped (``intrinsic'') and doped (``extrinsic'') two-dimensional (2D) graphene layers. We find that (1) intrinsic graphene is a marginal Fermi liquid with the imaginary part of the self-energy, $\mathrm{Im}\phantom{\rule{0.2em}{0ex}}\ensuremath{\Sigma}(\ensuremath{\omega})$, varying linearly in energy $\ensuremath{\omega}$ for small $\ensuremath{\omega}$, implying that the quasiparticle spectral weight vanishes at the Dirac point as ${(\mathrm{ln}\phantom{\rule{0.2em}{0ex}}\ensuremath{\omega})}^{\ensuremath{-}1}$; and (2) extrinsic graphene is a well-defined Fermi liquid with $\mathrm{Im}\phantom{\rule{0.2em}{0ex}}\ensuremath{\Sigma}(\ensuremath{\omega})\ensuremath{\sim}{\ensuremath{\omega}}^{2}\phantom{\rule{0.2em}{0ex}}\mathrm{ln}\phantom{\rule{0.2em}{0ex}}\ensuremath{\omega}$ near the Fermi surface similar to 2D carrier systems with parabolic energy dispersion. We provide analytical and numerical results for quasiparticle renormalization in graphene, concluding that all experimental graphene systems are ordinary 2D Fermi liquids since any doping automatically induces generic Fermi liquid behavior.
Back-Melting of a Horizontal Cloudy Ice Layer with Radiative Heating (1979)

This paper is concerned with the melting of a horizontal ice layer sticking to a substrate by using halogen lamps, which are comparatively short wave radiation sources. This radiation in the visible and infrared spectral range may be employed to remove ice from structures subject to atmospheric icing. It is concluded that the behavior of radiation transfer in a cloudy ice layer depends a great deal on the density of the cloudy ice including air bubbles which produce the scattering of radiation. Also the phenomenon of back-melting caused by radiant energy penetrating through the ice layer is observed. Moreover, it is shown that the melting rate of an ice layer can be predicted numerically by using the band model of extinction coefficient for cloudy ice assumed in this study.
Benefit of Clergy--A Legal Anomaly (1927)

Among the most prized privileges of the Medieval Church was benefit of clergy.This may be defined as an immunity by which clergymen accused of felony, could be tried only in their own courts.Not only did the ecclesiastical courts have exclusive jurisdiction in cases of offenses by clerks against criminal law, but also in all cases of offences by laymen against clerks.By this privilege the clergy acquired a peculiar sanctity which set them apart from the laity.The personal inviolability surrounding them gave them a great advantage in contests with civil authority and since the Church was held responsible only to divine law, it became almost independent of the civil power and in all differences with temporal rulers this privilege was of great value.This medieval custom was not established without a long and bitter struggle.It was not considered unreasonable that disputes between ecclesiastics should be settled by their bishops, and this was the established rule of the church from an early period.But the claim that the felonious clerk should not be tried in a temporal court and that all disputes between laymen and ecclesiastics should be settled in church courts was not easily granted.'Benefit of clergy had its origin in the high regard in which the Church and its officials were held by secular rulers.As early as 355 A. D., the Roman Emperor Constantius decreed that bishops could be tried only by bishops 2 and later Justinian allowed the clergy the right to have episcopal judges, though he carefully reserved the power of disregarding the exemption: "nisi princeps jubeat.' 3 The early British Church presents one
Instrumental System for Analysis of Information Systems Using Smart Cards Protection (2014)

Modern smart card is a multi-purpose tool that is used in many areas of science and technology [5]. Microprocessor cards are used for access control, e-commerce, identification and authentication, used as personal data protected storages, as the core of e-passports and documents. In circulation there are tens of millions of devices simultaneously, and it is all the more credible by both the producers and by users [7]. All this leads to increase of attention from both developers (to protect information) and intruders.

Refactoring-aware Software Configuration Management (2006)

Refactoring tools allow programmers to change source code much quicker than before. However, the complexity of these changes cause versioning tools that operate at a file level to lose the history of components. This problem can be solved by semantic, operation-based SCM with persistent IDs. We propose that versioning tools be aware of the pro- gram entities and the refactoring operations. MolhadoRef, our prototype, uses these techniques to ensure that it never loses history.
Fate and expression of the deleted mitochondrial DNA differ between human heteroplasmic skin fibroblast and Epstein-Barr virus-transformed lymphocyte cultures. (1993)

We report on the variant phenotypic expression of mitochondrial genotypes in cultured skin fibroblasts and Epstein-Barr virus-transformed lymphocyte cultures from a patient with Pearson syndrome (McKusick no. 260560). Both cell types harbored a heteroplasmic population of normal and deleted mtDNA molecules. The deletion encompassed five tRNA genes and seven genes encoding subunits of cytochrome c oxidase, complex I, and ATPase. Patient skin fibroblasts and lymphocytes harbored 60 and 80% of deleted mtDNA molecules, respectively, and initially displayed defective respiratory chain activities. In both cases, there was a progressive recovery of respiratory chain activities during in vitro cell proliferation. In cultured skin fibroblasts, the loss of the deleted mtDNA molecules accounted for the recovery of normal respiratory chain activities. These features were prevented by allowing respiratory chain-deficient cells to grow in the presence of uridine (200 microM). In Epstein-Barr virus-transformed lymphocytes containing 60% of deleted mtDNA, the recovery of respiratory chain activities was attributable to an increase in the mtRNA translation efficiency rather than to an increased content in mtDNA or mtRNA. The present study suggests that the variant cellular responses to abnormal mitochondrial genotypes might contribute to the tissue-specific expression of mitochondrial disorders in vivo.
