Advancing Data Weighted Averaging Technique for Multi-Bit Sigma&#x2013;Delta Modulators (2007)

Multibit sigma-delta modulators which employ the data weighted averaging (DWA) technique are plagued by base-band tone problems. The existing DWA-like techniques for solving these problems are categorized in this brief as tone-suppressing and tone-transferring techniques. Although tone-transferring techniques can achieve a better signal-to-noise-plus-distortion ratio than tone-suppressing techniques, they may behave unfavorably for input signals with dc components. A flexible DWA-like technique, designated as "advancing DWA" (ADWA), which can achieve both tone-suppressing and tone-transferring functions, is proposed. It can be configured as a tone-transferring technique by advancing the starting selection of the element array by a fixed step for the subsequent element selection cycle. Moreover, ADWA can also be configured as a tone-suppressing technique to reduce tones by randomly performing the advancing actions. Therefore, ADWA can be a reconfigurable technique that uses configuration settings from designers, or an auto-configurable technique that uses input signal detection schemes to set its configuration.
Effect of Sulfur Baths on Antioxidative Defense Systems, Peroxide Concentrations and Lipid Levels in Patients with Degenerative Osteoarthritis (2002)

The results presented here suggest that a sulfur bath therapy could cause a reduction in oxidative stress, alterations of SOD activities, and a tendency towards improvement of lipid levels.
Formation of competent Bacillus subtilis cells (1983)

The process of competent cell formation for transformation has been studied with early-stationary-phase (T1) cells of Bacillus subtilis which had been grown in an enriched Spizizen minimal medium and transferred to a second synthetic medium. Rifampin, chloramphenicol, and tunicamycin were strong inhibitors of competent cell formation, as well as vegetative growth. After formation, competent cells were no longer sensitive to the above agents. Methicillin and an inhibitor of chromosomal replication, hydroxyphenylazouracil, did not inhibit the development of competence. A D-alanine-requiring mutant strain developed competence even in the absence of D-alanine in the second medium. A T1-stage culture showed the activity of extracellular serine protease which is necessary for sporulation. Competent cell formation was completely blocked by 0.7 M ethanol, which is a specific inhibitor of early events during sporulation, including forespore septum formation. Competent cells were formed even in media which supported sporulation. The development of competence was also studied with spo0 mutants at 10 different loci. Most spo0 mutations repressed the development of competence except for spo0C, spo0G, and spo0J. These results suggest that competent cells are formed from early sporulating cells with the synthesis of cell wall materials and by factors whose genes are activated by the supply of nutrients. It is suggested that common steps are involved both in forespore septation and in competent cell formation.

Their structures were elucidated by two-dimensional NMR spectroscopy.
Antioxidant efficacy of amino acids in methyl linoleate at different relative humidities (1994)

Abstract Antioxidant efficacy of the amino acids methionine, tryptophan, aspartic acid, serine, alanine and arginine in methyl linoleate were compared to a methyl linoleate control at 2,50 or 79% relative humidity (RH) at 37°C. Antioxidant efficacy varied with RH and the individual amino acids. Arginine had the highest antioxidant efficacy at all RH values compared to the control. The efficacy of alanine was equal to that of arginine at RHs of 50 and 79% but was lower at 2% RH. The presence of aliphatic, alkaline amino, hydroxyl or thiol groups in the side chain of the amino acids increased the antioxidant efficacy at high RHs.
Selective GPS Jamming (2000)

As the use of GPS becomes more widespread, GPS 
jamming tests are increasingly more difficult to 
coordinate. Because GPS receivers are susceptible to 
jamming, a great number of users can be unintentionally 
jammed. GPS is a critical system for water navigation 
(which relies upon GPS augmented by the Coast Guard's 
differential system), cellular telephone networks (some of 
which rely upon GPS timing), air traffic (both private and 
commercial aircraft), and other civilian users (from 
hunters to hikers to rental cars). GPS jamming tests can 
also cause problems for the ranges on which tests are to 
be performed - if these ranges rely upon GPS for range 
instrumentation. With all these potential issues in mind, 
there remains a community wide need to test and train 
under the effects of GPS jamming. 
For the past three years, the Threat Systems Management 
Office at Redstone Arsenal, Alabama has been developing 
a threat simulator which will allow the military to test and 
train in a GPS jamming environment without interfering 
with civilian GPS users or range instrumentation GPS 
receivers. This program is known as Selective GPS 
Jamming. 

Selective GPS Jamming consists of two pieces of 
hardware. The first is a Control Signal Transmitter (CST). 
This transmitter radiates an open air RF signal that is 
close to the GPS center frequency (so that real world 
effects such as path loss, multipath, antenna masking, and 
body masking are represented) but is a benign (or non-
jamming) signal. The CST is mounted on the same 
platform as the threat (ground based or airborne) and uses 
the same type of antenna to match polarization and 
pattern coverage. The second piece is a Remote Jammer 
Unit (RJU) which is installed between the antenna and the 
GPS receiver under test. The RJU measures the power 
level of the control signal and injects an appropriate 
amount of jamming power directly into the front end of 
the GPS receiver under test. The RJU can also be 
configured to scale the injected jamming power levels 
allowing threats from milliwatts to hundreds of kilowatts 
to be represented with the same RJU/CST combination. 
Since the center frequency jamming signals are generated 
and controlled within the RJU, only receivers which have 
been fitted with an RJU are jammed. No other GPS 
receivers are affected. 
This paper consists of a detailed description of the 
XMGPS system and a comparison of actual jamming and 
selective jamming test results. Also discussed are the 
control signal characteristics, dynamic range power 
levels, operational distances, and FAA 
issues/involvement. The paper concludes with future 
devices and requirements as well as results of a training 
specific device.
Exenatide: NMR/CD evaluation of the medium dependence of conformation and aggregation state (2004)

Exenatide, synthetic exendin-4, is the first member of the incretin mimetic class of potential therapeutic agents. It has been the subject of extensive clinical trials in people with Type 2 diabetes. Results to date indicate that exenatide decreases postmeal blood glucose concentrations and that this effect is associated with weight loss. Prior NMR studies of exendin-4 utilized 30% trifluoroethanol because this medium affords sharp, high-resolution NMR spectra. These studies defined its three-dimensional structure in this medium. The NMR-derived ensemble included a novel tertiary structure motif that has subsequently been optimized, yielding water-soluble Trp-cage miniproteins. Prior to the present study, the structuring propensities (and aggregation/association state) of exendin-4 in strictly aqueous media had not been established. Studies of exendin-4 and N-terminally truncated analogs of exendin have established that the structuring propensities of these species are highly medium dependent. This study extends knowledge of the medium dependence of exendin structure to DMSO-water mixtures and to aqueous media mimicking the formulation conditions for this investigational drug. Exenatide retains a substantial helical propensity from residues 9-27 even in 98% DMSO. The addition of water leads to the appearance of NMR diagnostics of the Trp-cage formation. In strictly aqueous media (pH 4-4.4), exenatide is monomeric only at <10 microM peptide concentrations. Under these conditions the Trp cage is partially formed. NMR and CD data indicate that higher concentrations lead to helix bundle formation and that the helix/helix interactions involve residues 11-26. Both the N- and C-termini of the helix bundle state display rapid segmental motion.

The Provincial Party (2010)

The history of British Columbia has been marked by persistent attempts to reform provincial politics. Since 1920, these have frequently taken the form of advocating the election of an efficient non-partisan government unrestricted by organizational ties to federal parties or political machines. One significant attempt to achieve this goal may be seen in the history of the Provincial Party. Organized in 1922, the party ran fortyone candidates in the 1924 provincial general election. It elected three members to the Legislative Assembly, gained 24.2% of the popular vote, helped defeat both the leaders of the Liberal and Conservative parties and was credited with deciding the result in thirty-three of the forty-eight provincial ridings. Though the party soon disintegrated, its limited success offers evidence that, even in a period of relative economic and social stability, British Columbia voters were not committed to the traditional two party system. A reform party, promising the elimination of machine politics and governmental inefficiency, could obtain considerable electoral support. The Provincial Party had its origin in the convergence of two political developments in British Columbia in 1922. One of these was the failure of a group of dissatisfied Conservatives to force the resignation of the party leader, William John Bowser. The other was a movement among the United Farmers of British Columbia into the field of direct political action. The frustration of their individual efforts led to union and the formation of the Provincial Party with the first group providing most of the leadership and the second, a nucleus of popular support. Discontent within the Conservative party had been growing for a number of years. Bowser, a Vancouver lawyer and long-time power in the government of Sir Richard McBride, had become party leader and

Arthritis and rheumatism are neglected health priorities: a bibliometric study. (2001)

Arthritis and rheumatic diseases receive far less attention in the scientific literature than is warranted by their enormous and growing disease burden. Both research and dissemination are lacking and more adequate resources for these activities are indicated.
Vacancy–group-V-impurity atom pairs in Ge crystals doped with P, As, Sb, and Bi (2004)

The electronic properties and thermal stability of centers incorporating a vacancy and a group-V-impurity atom (P, As, Sb, or Bi) in Ge crystals have been investigated. The vacancy-group-V-impurity atom pairs ($E$ centers) have been induced by irradiation with $^{60}\mathrm{Co}$ $\ensuremath{\gamma}$ rays and studied by means of capacitance transient techniques with the use of Au-Ge Schottky barriers. It is argued that the $E$ centers in Ge have three charge states: double negative, single negative and neutral, and introduce two energy levels into the gap. There are pronounced changes in the activation energies of charge carrier emission for the particular states with the changes in the type of impurity atoms. The emission of an electron from the doubly negatively charged state of the centers is accompanied by a large change in entropy $(\ensuremath{\Delta}S)$, so, the free energy of the electron ionization, $\ensuremath{\Delta}G(\ensuremath{-}\ensuremath{-}∕\ensuremath{-})=\ensuremath{\Delta}H(\ensuremath{-}\ensuremath{-}∕\ensuremath{-})\ensuremath{-}T\ensuremath{\Delta}S(\ensuremath{-}\ensuremath{-}∕\ensuremath{-})$, changes significantly with temperature. Consequently, the position of the second acceptor level of the $E$ centers ${E(\ensuremath{-}\ensuremath{-}∕\ensuremath{-})={E}_{c}\ensuremath{-}\ensuremath{\Delta}G(\ensuremath{-}\ensuremath{-}∕\ensuremath{-})}$ is temperature dependent. In Ge crystals having shallow donor concentrations in the range ${10}^{13}--{10}^{15}\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}3}$ at equilibrium conditions half-occupancy of the doubly negatively charged state of the vacancy-group-V-impurity atom pairs occurs when the Fermi level is at ${E}_{c}\ensuremath{-}(0.18--0.22)\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$. Changes in the entropy of ionization and the energy of electron emission for the double negative state of the $E$ centers follow the Meyer-Neldel rule. It has been shown that the directly measured capture cross sections of electrons at the singly negatively charged $E$ centers are temperature dependent and can be described by the multiphonon-assisted capture model. The first acceptor level of the $E$ centers is in the lower part of the band gap. The formation of one vacancy--group-V-impurity atom complex results in the removal of at least two electrons from the conduction band in $n$-type Ge. It is thought that the $E$ centers are responsible for the fast free carrier removal and $n\ensuremath{\rightarrow}p$ conversion of the conductivity type in oxygen-lean Ge crystals upon electron- or $\ensuremath{\gamma}$-irradiation at room temperature. The thermal stability of the $E$ centers in Ge has been found to increase with an increase in the size of donor atoms.

Studies on bioemulsifier production by Acinetobacter strains isolated from healthy human skin (2001)

Investigation of skin commensals, especially acinetobacters, would lead to the discovery of novel bioemulsifiers with interesting properties. Attempts of screening and strain improvement directed towards skin commensals will open up new avenues for strains producing bioemulsifier on a commercial scale.
Morphology Transformation of Nanoscale Magnesium Hydroxide: from Nanosheets to Nanodisks (2006)

Nanoscale Mg(OH) 2 with different morphologies, from nanosheets, nanosquares, and nanodisks, have been successfully synthesized via a simple hydrothermal reaction of Mg(CH 3 COO) 2 and sodium hydroxide in the presence of citrate. Direct observation of transformation from nanosheets to nanodisks indicates clearly the growth of a Mg(OH) 2 nanocrystal. The structure and morphology of the resultant Mg(OH) 2 nanostructures were characterized by X‐ray powder diffraction (XRD), transmission electron microscopy (TEM), high‐resolution transmission electron microscopy (HRTEM), and selected area electron diffraction patterns (SAED). A possible formation mechanism of the Mg(OH) 2 nanostructures is proposed based on the oriented aggregation mechanism.

Semicerchio. Rivista di poesia comparata LV (2016/2) 30 anni (2018)

Forse per effetto dell’onda lunga dell’idealismo crociano – per il quale la poesia è espressione del genio individuale e trova la propria ultima verità in se stessa – o a causa della manifesta subalternità rispetto a una forma storicamente molto più affine alle metodologie della comparatistica come quella del romanzo, lo studio comparato delle forme poetiche si è tradizionalmente presentato, tanto in Italia quanto altrove, come una delle “cenerentole” della disciplina. Un esito, dunque, che non si deve tanto alla qualità intrinseca delle singole ricerche, quanto alla loro scarsità numerica e al costante declino del prestigio conferito a tali indagini.
Organic Transistor Arrays Integrated with Finger‐Powered Microfluidics for Multianalyte Saliva Testing (2016)

A compact multianalyte biosensing platform is reported, composed of an organic electrochemical transistor (OECT) microarray integrated with a pumpless "finger-powered" microfluidic, for quantitative screening of glucose, lactate, and cholesterol levels. A biofunctionalization method is designed, which provides selectivity towards specific metabolites as well as minimization of any background interference. In addition, a simple method is developed to facilitate multi-analyte sensing and avoid electrical crosstalk between the different transistors by electrically isolating the individual devices. The resulting biosensing platform, verified using human samples, offers the possibility to be used in easy-to-obtain biofluids with low abundance metabolites, such as saliva. Based on our proposed method, other types of enzymatic biosensors can be integrated into the array to achieve multiplexed, noninvasive, personalized point-of-care diagnostics.

Dynamic Performance Profiling of Cloud Caches (2014)

Large-scale in-memory object caches such as memcached are widely used to accelerate popular web sites and to reduce burden on backend databases. Yet current cache systems give cache operators limited information on what resources are required to optimally accommodate the present workload. This paper focuses on a key question for cache operators: how much total memory should be allocated to the in-memory cache tier to achieve desired performance?
Transduction of Tumor Necrosis Factor–Related Apoptosis-Inducing Ligand into Hematopoietic Cells Leads to Inhibition of Syngeneic Tumor Growth <i>In vivo</i> (2006)

Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is a member of the TNF family of cytokines and has been shown to induce cell death in many types of tumor and transformed cells but not in normal cells. This tumor-selective property has made TRAIL a promising candidate for the development of cancer therapy. However, safety issues are a concern because certain preparations of recombinant TRAIL protein were reported to induce toxicity in normal human hepatocytes in culture. In addition, previous studies on tumor selectivity of exogenous TRAIL protein were carried out in xenograft models, which do not directly address the tumor selectivity issue. It was not known whether exogenous or overexpression of TRAIL in a syngeneic system could induce tumor cell death while leaving normal tissue cells unharmed. Thus, the tumor selectivity of TRAIL-induced apoptosis remains to be further characterized. In our study, we established mice that overexpress TRAIL by retroviral-mediated gene transfer in bone marrow cells followed by bone marrow transplantation. Our results show that TRAIL overexpression is not toxic to normal tissues, as analyzed by hematologic and histologic analyses of tissue samples from TRAIL-transduced mice. We show for the first time that TRAIL overexpression in hematopoietic cells leads to significant inhibition of syngeneic tumor growth in certain tumor lines. This approach may be used further to identify important molecules that regulate the sensitivity of tumor cells to TRAIL-induced cell death in vivo.
