Ab Initio Calculation of the Cr K Edge in Al2O3Cr3 (2005)

The red color of ruby (α-Al2O3:Cr3+) is assigned to transitions between 3d states of the chromium ion. A precise description of the structural and electronic environment of the Cr3+ ion in its slightly distorted octahedral site (C3 symmetry) is needed to understand the cause of the color. We have analysed the Cr K-edge in Cr3+ with a reciprocal space approach that allows the computation of self-consistent spin polarized charge density for large unit cells, beyond the traditional "muffin-tin" approximation. Structural and electronic information is deduced from the calculation.
Comparison of air and ground conflict detection and resolution algorithms and their implications (2003)

Decision support tools (DSTs) designed to allow airspace users to maintain separation will become increasingly critical as more direct routes, free maneuvering, self-separation, and distributed air-ground traffic management concepts evolve. One type of DST, conflict detection and resolution (CD&R) tools, will play an important role in air traffic management both on the ground and in the air. A number of aircraft CD&R algorithms have been developed in recent years; however, there is no detailed competitive analysis that clearly demonstrates their effectiveness and efficiency. Kuchar and Yang (1997) surveyed multiple algorithms and documented their strengths, but the impact on the users of these algorithms has not yet been tested in simulated conditions with realistic traffic situations. Most of the studies examining individual algorithm effectiveness use either the fast-time or Monte Carlo process. Therefore, there is a need to examine and compare the effectiveness of these algorithms from a human-centered perspective.

The ATLAS hadronic tile calorimeter: from construction toward physics (2006)

The Tile Calorimeter, which constitutes the central section of the ATLAS hadronic calorimeter, is a non-compensating sampling device made of iron and scintillating tiles. The construction phase of the calorimeter is nearly complete, and most of the effort now is directed toward the final assembly and commissioning in the underground experimental hall. The layout of the calorimeter and the tasks carried out during construction are described, first with a brief reminder of the requirements that drove the calorimeter design. During the last few years a comprehensive test-beam program has been followed in order to establish the calorimeter electromagnetic energy scale, to study its uniformity, and to compare real data to Monte Carlo simulation. The test-beam setup and first results from the data are described. During the test-beam period in 2004, lasting several months, data have been acquired with a complete slice of the central ATLAS calorimeter. The data collected in the test-beam are crucial in order to study algorithms for hadronic energy reconstruction using single particles. The generalization of these algorithms to reconstruct jet energies will be the starting point for numerous physics studies in which jets play a leading role. The results obtained in applying these algorithms to simulated di-jet events are given in the last section of the note.
Electrodeposition of ZnO on ITO Electrode by Potential Modulation Method (2001)

We report the effect of the concentration of hydroxide ion adsorbed (OHad) on indium tin oxide (ITO) in the electrodeposition of zinc oxide (ZnO) by potential modulation method. We found that by applying an optimal constant potential of –0.72 V, X-ray diffraction (XRD) peak intensity of crystalline phase indicating ZnO (100) and ZnO (101) deposited in oxygen containing solution was significantly higher than that of ZnO formed in oxygen free solution. ZnO was islanding on ITO substrate in an oxygen free solution, while uniform ZnO underwent bulk deposition with higher growth rate due to higher concentration of OHad resulted from dissolved oxygen. Thus, morphological images were in good agreement with the crystal structural analysis. In pulsed potential method, several ZnO peaks in ex situ XRD analysis were obtained on ITO substrate as optimal cathodic potential of –0.72 V for 5 s was superimposed on off-time of 5 s at open-circuit potential in each cycle. When relatively shorter cathodic time of 1 s was applied, however, we did not obtain any XRD peak of ZnO, because it might be due to the lack of the critical concentration of OHad to form ZnO on the surface.

Noncovalent Interaction-Driven Stereoselectivity of Copper(II) Complexes with Cyclodextrin Derivatives of<scp>l</scp>- and<scp>d</scp>-Carnosine (2011)

L-Carnosine (β-alanyl-L-histidine, LCar) is the most widely and abundantly distributed copper(II)-coordinating endogenous dipeptide. Though its physiological role has not been completely understood yet, many functions have been proposed for this compound. LCar might be crucial in the potential reduction or prevention of several pathologies in which the metal ions are thought to be involved. The potential therapeutic applications of LCar are drastically limited because of hydrolysis by specific dipeptidases (carnosinases). D-Carnosine (DCar), the enantiomer of the naturally occurring dipeptide, shows the same properties as those of LCar, but it is not hydrolyzed by carnosinases. Chemical modification of LCar has been proposed as a promising strategy to reduce its enzymatic hydrolysis; conjugation of a carbohydrate moiety may also improve site-specific transport to different tissues, which would enhance the peptide bioavailability. On this basis, we have functionalized DCar with β-cyclodextrin (CDDCar) and characterized the compound via NMR. The copper(II) binding properties of the new DCar derivative were investigated by spectroscopic techniques (UV-vis, circular dichroism, electron paramagnetic resonance) and potentiometric measurements. The results surprisingly revealed a pronounced difference from the analogous LCar derivative (CDLCar), especially concerning the dimeric species. The spectroscopic data show that this stereoselectivity is driven by noncovalent interactions, namely, hydrogen bonds, CH-π interactions, and steric and hydrophobic effects of the cyclodextrin cavity.
Effect of Gibberellic Acid on Cell Division and Cell Elongation in Anthers of the Gibberellin Deficient <i>gib‐1</i> Mutant of Tomato (2001)

Abstract: Analysis of flower development in the gibberellin (GA) deficient gib‐1 tomato mutant showed that while flower development is arrested the anther growth slowed down unless GA was applied. Northern blot analyses showed that treatment with GA 3 enhanced the expression of genes which are correlated with DNA replication (histones h1 and h2b ) and cell elongation (expansin and α‐tubulin). In anthers, at developmental arrest, cell elongation was affected in the tapetum, pollen mother cells and epidermal cells. Elongation was significantly less in the longitudinal direction, while in the transverse direction outer tapetum and pollen mother cells were also smaller. Except for the outer tapetum, the cell numbers were the same as in wild‐type tomato, indicating that cell division was less influenced. Scanning electron microscopy revealed that on the lateral surface of gib‐1 anthers the epidermal cells that were affected in their elongation due to GA deficiency did not differentiate into interlocking hairs. Induction of hair development, of which the timing was similar to wild type, occurred after treatment with GA 3 , GA 1 , GA 4 and GA 9 , while GA 20 was less effective. Analysis of the in situ localization of expansin and histone h2b transcripts in gib‐1 anthers after GA 3 treatment revealed that the increased mRNA accumulation was predominantly localized in the cells that were less elongated compared to wild‐type cells. The consequence of reduced cell elongation due to GA deficiency on anther development is discussed.
The cell surface protein Ag43 facilitates phage infection of Escherichia coli in the presence of bile salts and carbohydrates (2002)

It was found that infection of Escherichia coli by bacteriophage lambda is inhibited in the presence of certain bile salts and carbohydrates when cells are in the "OFF" state for production of the phase-variable cell surface protein antigen 43 (Ag43). The inhibition of phage growth was found to be due to a significant impairment in the process of phage adsorption. Expression of the gene encoding Ag43 (agn43) from a plasmid or inactivation of the oxyR gene (encoding an activator of genes important for defence against oxidative stress) suppressed this inhibition. A mutation, rpoA341, in the gene encoding the alpha subunit of RNA polymerase also facilitated phage adsorption in the presence of bile salts and carbohydrates. The rpoA341 mutation promoted efficient production of Ag43 in a genetic background that would otherwise be in the "OFF" phase for expression of the agn43 gene. Analysis of a reporter gene fusion demonstrated that the promoter for the agn43 gene was more active in the rpoA341 mutant than in the otherwise isogenic rpoA(+) strain. The combined inhibitory action of bile salts and carbohydrates on phage adsorption and the abolition of this inhibition by production of Ag43 was not restricted to lambda, as a similar phenomenon was observed for the coliphages P1 and T4.
The importance of phase in image processing filters (1975)

We demonstrate that phase accuracy is extremely important in image processing filters and express the hope that more work will be done on the development of filter design techniques which use phase as well as magnitude specifications.
Reconfigurable liquid crystal droplets using a dielectric force (2009)

Dielectric force-induced shape change of liquid crystal (LC) droplets which are randomly dispersed in a liquid polymer is demonstrated. By applying a sufficiently high voltage, the isolated spherical LC droplets are coalesced to form a planar layer, while the cylindrical LC droplets which make contact on both substrate surfaces cannot be deformed easily. On the contrary, each cylindrical LC droplet functions as a swollen well to unite the adjacent LC droplets. The dynamic behavior for flattening the spherical LC droplets is also studied. Potential applications of these reconfigurable LC droplets for various photonic devices are discussed.

Protocols for simultaneous signing contracts (2009)

Signing electronic messages authentication is an issue of significant importance for computer and telecommunication systems. To solve efficiently some special practical problems the multisignature protocols are applied. New multisignature protocols based on the elliptic curves and discrete logarithm problem in finite groups are proposed to solve the problem of simultaneous signing contracts. The protocols provide simultaneous generation of the collective digital signature. There are considered the following two cases: 1) a group of signers are signing simultaneously one document and 2) several different groups of signers are signing several different documents. The signature verification is performed using collective public key computed from the whole set of individual public keys as the some convolution of this set.

eIF2α Kinase PKR Modulates the Hypoxic Response by Stat3-Dependent Transcriptional Suppression of HIF-1α (2010)

Hypoxia within the tumor microenvironment promotes angiogenesis, metabolic reprogramming, and tumor progression. In addition to activating hypoxia-inducible factor-1α (HIF-1α), cells also respond to hypoxia by globally inhibiting protein synthesis via serine 51 phosphorylation of translation eukaryotic initiation factor 2α (eIF2α). In this study, we investigated potential roles for stress-activated eIF2α kinases in regulation of HIF-1α. Our investigations revealed that the double-stranded RNA-dependent protein kinase R (PKR) plays a significant role in suppressing HIF-1α expression, acting specifically at the level of transcription. HIF-1α transcriptional repression by PKR was sufficient to impair the hypoxia-induced accumulation of HIF-1α and transcriptional induction of HIF-1α-dependent target genes. Inhibition of HIF-1A transcription by PKR was independent of eIF2α phosphorylation but dependent on inhibition of the signal transducer and activator of transcription 3 (Stat3). Furthermore, HIF-1A repression required the T-cell protein tyrosine phosphatase, which acts downstream of PKR, to suppress Stat3. Our findings reveal a novel tumor suppressor function for PKR, which inhibits HIF-1α expression through Stat3 but is independent of eIF2α phosphorylation.
Lasers for LISA: Overview and phase characteristics (2009)

We have investigated two alternative laser systems for the Laser Interferometer Space Antenna (LISA). One consisted of the laser of LISA's technology precursor LISA Pathfinder and a fiber amplifier originally designed for a laser communication terminal onboard TerraSar-X. The other consisted of a commercial fiber distributed feedback (DFB) laser seeding a fiber amplifier. We have shown that the TerraSar-X amplifier can emit more than 1 W without the onset of stimulated Brillouin scattering as required by LISA. We have measured power noise and frequency noise of the LISA Pathfinder laser (LPL) and the fiber laser. The fiber laser shows comparable or even lower power noise than the LPL. LISA will use electro-optical modulators (EOMs) between seed laser and amplifier for clock noise comparison between spacecraft. This scheme requires that the excess noise added by the amplifiers be negligible. We have investigated the phase characteristics of two fiber amplifiers emitting 1 W and found them to be compatible with the LISA requirement on amplifier differential phase noise.
Polygraph realization for data visualization and analysis (2007)

A polygraph is a tool which provides access, visualization and analysis for large amounts of recorded physiologic data. The goal of this work is to provide an open source framework for studying and detailing data. Recorded data, internal epochs, montages, and a graphic user interface (GUI) are linked together with this realization.
A method for in vitro culture of rat Zymbal gland: use in mechanistic studies of benzene carcinogenesis in combination with 32P-postlabeling. (1989)

Zymbal glands were excised bilaterally from the ear ducts of female Sprague-Dawley rats (three/group), minced into approximately four fragments per gland, and transferred into a microtiter plate containing 1.5 mL per well of Waymouth's tissue culture medium supplemented with fetal calf serum, hydrocortisone, insulin, and gentamicin. After addition of a test compound or solvent vehicle, plates were incubated for 6, 24, 48, or 96 hr at 37 degrees C in a humidified atmosphere of 5% CO2 in air. Tissue in culture for 6 hr was histologically indistinguishable from the freshly excised tissue, while that in culture for 24, 48, and 96 hr showed a progressive deterioration often with necrosis and/or squamous metaplasia. More pronounced deterioration was noted in samples treated with 750 or 1500 micrograms/mL of benzene. Using a nuclease P1-enhanced 32P-postlabeling assay, aromatic DNA adducts were detected in cultured Zymbal glands exposed for 48 hr to benzene and its derivatives, as well as to 7,12-dimethylbenzanthracene (DMBA) and 2-acetylaminofluorene (AAF). Benzene produced very low levels of adducts (0.5 adducts per 10(9) nucleotides), whereas its congeners produced relatively high levels of adducts (50-2000 lesions per 10(9) nucleotides), which decreased in the order benzoquinone greater than hydroquinone greater than phenol greater than benzenetriol greater than catechol. Each adduct profile overall was characteristic for the compound studied, suggesting the formation of compound-specific electrophiles. AAF and DMBA adducts were identical to those formed in vivo in animals. Our results show that the Zymbal glands are capable of metabolizing different carcinogens to DNA-reactive intermediates, a process that may be causally associated with tumor formation in vivo in this organ.

Deficiency of the Fas apoptosis pathway without Fas gene mutations is a familial trait predisposing to development of autoimmune diseases and cancer. (2000)

Fas/Apo-1 (CD95) triggers programmed cell death (PCD) and is involved in immune response control and cell-mediated cytotoxicity. In the autoimmune/lymphoproliferative syndrome (ALPS), inherited loss-of-function mutations of the Fas gene cause nonmalignant lymphoproliferation and autoimmunity. We have recently identified an ALPS-like clinical pattern (named autoimmune lymphoproliferative disease [ALD]) in patients with decreased Fas function, but no Fas gene mutation. They also displayed decreased PCD response to ceramide, triggering a death pathway partially overlapping that used by Fas, which suggests that ALD is caused by downstream alterations of the Fas signaling pathway. Decreased Fas function is also involved in tumor development, because somatic mutations hitting the Fas system may protect neoplastic cells from immune surveillance. This work assessed the inherited component of the ALD defect by evaluating Fas- and ceramide-induced T-cell death in both parents and 4 close relatives of 10 unrelated patients with ALD. Most of them (22 of 24) displayed defective Fas- or ceramide-induced (or both) cell death. Moreover, analysis of the family histories showed that frequencies of autoimmunity and cancer were significantly increased in the paternal and maternal line, respectively. Defective Fas- or ceramide-induced T-cell death was also detected in 9 of 17 autoimmune patients from 7 families displaying more than a single case of autoimmunity within first- or second-degree relatives (multiple autoimmune syndrome [MAS] patients). Autoimmune diseases displayed by ALD and MAS families included several organ-specific and systemic forms. These data suggest that ALD is due to accumulation of several defects in the same subject and that these defects predispose to development of cancer or autoimmune diseases other than ALPS/ALD.
Lowering β-Amyloid Levels Rescues Learning and Memory in a Down Syndrome Mouse Model (2010)

beta-amyloid levels are elevated in Down syndrome (DS) patients throughout life and are believed to cause Alzheimer's disease (AD) in adult members of this population. However, it is not known if beta-amyloid contributes to intellectual disability in younger individuals. We used a gamma-secretase inhibitor to lower beta-amyloid levels in young mice that model DS. This treatment corrected learning deficits characteristic of these mice, suggesting that beta-amyloid-lowering therapies might improve cognitive function in young DS patients.
Strain Variation in 59Fe Absorption During Aflatoxicosis (1981)

Strain variation of iron absorption in response to dietary aflatoxin was studied using two commercial broiler strains and a nonselected randombred strain. Aflatoxin depressed chick body weights and increased mortalities in each strain. Hematocrits were significantly reduced in the commercial broilers receiving the toxin, but not in the randombreds. Aflatoxin reduced iron absorption in each strain regardless of the presence of anemia.
