description: Trichohyalin is an intermediate filament-associated protein that associates in regular arrays with keratin intermediate filaments (KIF) of the inner root sheath cells of the hair follicle and the granular layer of the epidermis and is a known substrate of transglutaminases. We have determined the full-length sequence of human trichohyalin by use of RNA-mediated anchored polymeraee chain reaction methods and from a genomic clone and analyzed its potential secondary structure. We show here that trichohyalin may have at least three important functions in these cells. The protein of 248 kDa is unusual in that it contains one of the highest contents of charged residues of any protein.Trichohyalin is an intermediate filament-associated protein that associates in regular arrays with keratin intermediate filaments (KIF) of the inner root sheath cells of the hair follicle and the granular layer of the epidermis and is a known substrate of transglutaminases.

description: Devoted to the interests of the Boundary Mining District. The Phoenix Pioneer was published in Phoenix, in the Kootenay Boundary region of southern British Columbia, and ran from April 1898 to May 1916. The Pioneer was published by the Pioneer Publishing Company, which was managed by W. B. Wilcox (from 1899-1908) and Thomas Alfred Love (from 1908-1911). On August 12th, 1910, the headquarters of the Pioneer burned down, together with a large portion of the town of Phoenix itself, and the paper consequently suffered serious financial difficulties. On April 11th, 1911, the Pioneer was sold to Gilbert Kay, who published and edited the paper until May 1916. The paper was published under a variant title, the Phoenix Pioneer and Boundary Mining Journal, both from 1903-1910 and from 1911-1912.

description: Apoptosis is an important physiological process that involves the deletion of specific cells in a controlled and timely manner. A biochemical hallmark typifying apoptosis in normal lymphocytes is DNA cleavage caused by a calcium-dependent nuclease. We have previously identified and purified an 18-kDa nuclease (NUC18) from glucocorticoid-treated rat thymocytes whose activity is associated with this apoptotic DNA fragmentation. Partial protein sequencing of pure NUC18 has generated two peptide sequences that have a remarkable similarity to rat cyclophilin A and other members of the cyclophilin family.

Determination of the quantum part of the truly nonperturbative Yang-Mills vacuum energy density in the covariant gauge QCD

Year: 2000
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Using the effective potential approach for composite operators, we have formulated a general method of calculation of the truly nonperturbative Yang-Mills vacuum energy density in the covariant gauge QCD ground state quantum models. It is defined as an integration of the truly nonperturbative part of the full gluon propagator over the deep infrared region (soft momentum region). A nontrivial minimization procedure makes it possible to determine the value of the soft cutoff in terms of the corresponding nonperturbative scale parameter, which is inevitably present in any nonperturbative model for the full gluon propagator. We have shown for specific models of the full gluon propagator explicitly that the use of the infrared enhanced and finite gluon propagators lead to the vacuum energy density which is finite, always negative and it has no imaginary part (stable vacuum), while the infrared vanishing propagators lead to unstable vacuum and therefore they are physically unacceptable.

description: The amino acid sequence requirements for androgen-dependent androgen receptor nuclear import were determined by immunostaining transiently expressed full-length wild type and mutant human androgen receptors (AR) in monkey kidney COS cells and measuring transcriptional activity by cotransfection with a luciferase reporter vector in monkey kidney CV1 cells. Mutagenesis studies revealed a bipartite nuclear targeting sequence in the DNA binding and hinge regions at amino acids 617-633, consisting of two clusters of basic amino acids separated by 10 amino acids, (sequence: see text). In a series of deletion mutants, AR NH2-terminal fragments (residues 1-639 through 1-723) displayed constitutive nuclear import, and transcriptional activity was similar to that of the ligand-activated full-length wild type AR. In contrast, nuclear import and transcriptional activation were inhibited by sequence extensions into the steroid-binding domain (1-771). Constitutive nuclear import was regained in part by NH2-terminal deletions of full-length AR. Expression of AR/pyruvate kinase chimeras defined a sequence required for pre-dominant nuclear localization as residues 580-661, comprised of the second zinc finger region of the DNA-binding domain, the 17-amino-acid putative targeting sequence, and 28 residues of flanking carboxyl-terminal sequence. These studies suggest that the bipartite nuclear targeting sequence of AR includes flanking sequence and is modulated by interactions between the NH2-and carboxyl-terminal regions.

We numerically estimate that the Riverside approximation is not precise enough to determine the three-body Coulomb correction factor in the correlation function, if the characteristic HBT radius parameter is 5 - 10 fm, which is the range of interest in high-energy heavy ion physics.

Spin-flip scattering in the quantum Hall regime

description: We present a microscopic theory of spin-orbit coupling in the integer quantum Hall regime. The spin-orbit scattering length is evaluated in the limit of long-range random potential. The spin-flip rate is shown to be determined by rare fluctuations of anomalously high electric field. A mechanism of strong spin-orbit scattering associated with exchange-induced spontaneous spin-polarization is suggested. Scaling of the spin-splitting of the delocalization transition with the strength of spin-orbit and exchange interactions is also discussed.

A single promoter directs both housekeeping and erythroid preferential expression of the human ferrochelatase gene.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: We have isolated and characterized the 5'-flanking region of the gene for human ferrochelatase (HFC), the last enzyme of the heme biosynthetic pathway. The proximal promoter of the gene is contained within a region that structurally resembles a CpG island and is devoid of general cis elements such as TATA and CAAT boxes. Recognition sites for the ubiquitous Sp1 family of transcription factors, as well as for the erythroid-specific trans-acting factors NF-E2 and GATA-1 were found, and binding of regulatory proteins to these elements was analyzed by in vitro DNase I protection assays. The contribution of the various cis elements to both ubiquitous and erythroid preferential expression of the HFC gene was assessed by using transient transfection assays. These showed that a minimal Sp1-driven promoter devoid of the upstream erythroid-specific elements was sufficient for erythroid preferential expression of the HFC gene. However, elimination of a repressor sequence lying between the minimal promoter and the erythroid-specific elements resulted in high levels of expression in human erythroleukemic K562 cells only when the cis elements recognized by GATA-1 and NF-E2 were present, suggesting that the activity of these factors is regulated by a downstream repressor in erythroid cells.
Wino Cold Dark Matter from Anomaly-Mediated SUSY Breaking

Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The cosmological moduli problem is discussed in the framework of sequestered sector/anomaly-mediated supersymmetry (SUSY) breaking. In this scheme, the gravitino mass (corresponding to the moduli masses) is naturally 10 - 100 TeV, and hence the lifetime of the moduli fields can be shorter than $\sim 1 sec$. As a result, the cosmological moduli fields should decay before big-bang nucleosynthesis starts. Furthermore, in the anomaly-mediated scenario, the lightest superparticle (LSP) is the Wino-like neutralino. Although the large annihilation cross section means the thermal relic density of the Wino LSP is too small to be the dominant component of cold dark matter (CDM), moduli decays can produce Winos in sufficient abundance to constitute CDM. If Winos are indeed the dark matter, it will be highly advantageous from the point of view of detection. If the halo density is dominated by the Wino-like LSP, the detection rate of Wino CDM in Ge detectors can be as large as $0.1 - 0.01$ event/kg/day, which is within the reach of the future CDM detection with Ge detector. Furthermore, there is a significant positron signal from pair annihilation of Winos in our galaxy which should give a spectacular signal at AMS.

description: A compelling feature of relativistic mean-field phenomenology has been the reproduction of spin-orbit splittings in finite nuclei after fitting only to equilibrium properties of infinite nuclear matter. This successful result occurs when the velocity dependence of the equivalent central potential that leads to saturation arises primarily because of a reduced nucleon effective mass. The spin-orbit interaction is then also specified when one works in a four-component Dirac framework. Here the nature of the spin-orbit force in more general chiral effective field theories of nuclei is examined, with an emphasis on the role of the tensor coupling of the isoscalar vector meson (omega) to the nucleon.

subject: FOS: Physical sciences

description: In addition to being a prime candidate for a fundamental unified theory of all interactions in nature, string theory provides a natural setting to understand gauge field theories. This is linked to the concept of "D-branes": extended, solitonic excitations of string theory which can be studied using techniques of string theory and which support gauge fields localized along their world-volumes. It follows that the techniques of string theory can be very useful even for those particle physicists who are not specifically interested in unification and/or quantum gravity. In this talk I attempt to review how strings help us to understand fields. The discussion is restricted to 3+1 spacetime dimensions.

description: Body-image disturbances are key among the diagnostic criteria for anorexia nervosa and bulimia nervosa. However, the specific nature of this disturbance is not precisely defined by DSN-III-R or DSN-IV. The numerous body-image assessment techniques have generated inconsistent and conflicting results concerning the nature of body image in the eating disorders. This study is the first quantitative review, a meta-analysis of (n = 59) studies of body image among anorexics and bulimics relative to controls. The results indicated that attitudinal measures of body dissatisfaction, including perceptual self-ideal discrepancy measures, produce much larger effect sizes for clinical populations than do perceptual assessments of size estimation accuracy. Attitudinal measures of body image also differentiate bulimic and anorexic groups, whereas perceptual distortion assessments do not.
Wormholes in generalized hybrid metric-Palatini gravity obeying the matter null energy condition everywhere

description: Wormhole solutions in a generalized hybrid metric-Palatini matter theory, given by a gravitational Lagrangian $f\left(R,\cal{R}\right)$, where $R$ is the metric Ricci scalar, and $\mathcal{R}$ is a Palatini scalar curvature defined in terms of an independent connection, and a matter Lagrangian, are found. The solutions are worked in the scalar-tensor representation of the theory, where the Palatini field is traded for two scalars, $φ$ and $ψ$, and the gravitational term $R$ is maintained. The main interest in the solutions found is that the matter field obeys the null energy condition (NEC) everywhere, including the throat and up to infinity, so that there is no need for exotic matter. The wormhole geometry with its flaring out at the throat is supported by the higher-order curvature terms, or equivalently, by the two fundamental scalar fields, which either way can be interpreted as a gravitational fluid. Thus, in this theory, in building a wormhole, it is possible to exchange the exoticity of matter by the exoticity of the gravitational sector. The specific wormhole displayed, built to obey the matter NEC from the throat to infinity, has three regions, namely, an interior region containing the throat, a thin shell of matter, and a vacuum Schwarzschild anti-de Sitter (AdS) exterior. For hybrid metric-Palatini matter theories this wormhole solution is the first where the NEC for the matter is verified for the entire spacetime keeping the solution under asymptotic control. The existence of this type of solutions is in line with the idea that traversable wormholes bore by additional fundamental gravitational fields, here disguised as scalar fields, can be found without exotic matter. Concomitantly, the somewhat concocted architecture needed to assemble a complete wormhole solution for the whole spacetime may imply that in this class of theories such solutions are scarce.

description: Over a large fraction of phase space a combination of an operator product and heavy quark expansions effectively turn the decay $\bar B -> D^{(*)0} e+e-$ into a ``short distance'' process, i.e., one in which the weak and electromagnetic interactions occur through single local operators. These processes have an underlying W-exchange quark diagram topology and are therefore Cabibbo allowed but suppressed by combinatoric factors and short distance QCD corrections. Our technique allows a clearer exploration of these effects. For the decay $\bar B_{d,s} -> J/psi(η_c) e+e-$ one must use a non-relativistic (NRQCD) expansion, in addition to an operator product expansion and a heavy quark effective theory expansion. We estimate the decay rates for $\bar B_{d,s} -> J/psi e+e-$, $\bar B_{d,s} -> eta_c e+e-$, $\bar B_{d,s} -> D^{*0} e+e-$ and $\bar B_{d,s} -> D^{0} e+e-$.

description: We present an extension of the previously proposed mean-field renormalization method to model Hamiltonians which are characterized by more than just one type of interaction. The method rests on scaling assumptions about the magnetization of different sublattices of the given lattice and it generates as many flow equations as coupling constants without arbitrary truncations on the renormalized Hamiltonian. We obtain good results for the test case of Ising systems with an additional second-neighbor coupling in two and three dimensions. An application of the method is also done to a morphological model of interacting surfaces introduced recenlty by Likos, Mecke and Wagner [J. Chem. Phys. {\bf{102}}, 9350 (1995)].

description: In this paper a quaternion approach of enhancement method is proposed in which color in the image is considered as a single entity. This new method is referred as the alpha-rooting method of color image enhancement by the two-dimensional quaternion discrete Fourier transform (2-D QDFT) followed by a spatial transformation. The results of the proposed color image enhancement method are compared with its counterpart channel-by-channel enhancement algorithm by the 2-D DFT. The image enhancements are quantified to the enhancement measure that is based on visual perception referred as the color enhancement measure estimation (CEME). The preliminary experiment results show that the quaternion approach of image enhancement is an effective color image enhancement technique.

Activated or dominant inhibitory mutants of Rap1A decrease the oxidative burst of Epstein-Barr virus-transformed human B lymphocytes

description: Rap1A is a GTP-binding protein of the Ras superfamily that is highly abundant in phagocyte membranes. Although Rap1A copurifies with cytochrome b558, a component of the superoxide-generating NADPH oxidase complex of human phagocytes and B lymphocytes, the involvement of Rap1A in the regulation of the oxidative burst in these cells has not been clearly established. Therefore, we have stably transfected human Epstein-Barr virus-transformed B lymphocytes that possess an activable NADPH oxidase complex with cDNAs for mutants of Rap1A "locked" in a GTP-bound (63E) and GDP-bound (17N) state. Both the 17N and 63E mutants of Rap1A inhibited phorbol ester-stimulated O2-. production by 50 and 80%, respectively, while transfection with cDNA for wild-type Rap1A had no effect on the respiratory burst. No effects of the Rap1A mutants on cell viability, proliferation, expression of cell-surface markers, or phorbol 12-myristate 13-acetate-stimulated interleukin-8 generation were detected. These data demonstrate that Rap1A is a regulator of O2-. formation in intact cells. Furthermore, the inhibitory effect of both GTP- as well as GDP-bound mutants indicates that Rap1A functions in a dynamic cycle as opposed to a unidirectional pathway, as is the case for the other NADPH oxidase regulatory GTP-binding protein, Rac.

description: Expression studies with skeletal and cardiac muscle cDNAs have suggested that the putative cytoplasmic loop region of the dihydropyridine receptor (DHPR) alpha 1 subunit between transmembrane repeats II and III (DCL) is a major determinant of the type of excitation-contraction coupling (skeletal or cardiac) in rescued dysgenic muscle cells (Tanabe, T., Beam, K. G., Adams, B. A., Niidome, T., and Numa, S. (1990) Nature 346, 567-569). In this study, the possibility of a direct functional interaction with the sarcoplasmic reticulum ryanodine receptor/Ca2+ release channel has been tested by expressing the DCLs of the mammalian skeletal and cardiac muscle DHPR alpha 1 subunit in Escherichia coli. The purified peptides activated the skeletal muscle ryanodine receptor/Ca2+ release channel in single channel and [3H]ryanodine binding measurements, by increasing channel open probability and the affinity of [3H]ryanodine binding, respectively. The two peptides did not activate the cardiac muscle Ca2+ release channel. Other proteins (polylysine, serum albumin) also increased [3H]ryanodine binding and Ca2+ release channel activity, but their activation mechanisms were distinguishable from DCLs. These results show that the II-III cytoplasmic loop of the skeletal and cardiac DHPR alpha 1 subunit functionally interacts with the skeletal, but not cardiac, muscle Ca2+ release channel. Furthermore, our studies suggest that in addition to the DHPR, the sarcoplasmic reticulum Ca2+ release channel may determine the type of E-C coupling that exists in muscle.

description: By means of periodic orbit theory and deformed cavity model, we have investigated semiclassical origin of superdeformed shell structure and also of reflection-asymmetric deformed shapes. Systematic analysis of quantum-classical correspondence reveals that bifurcation of equatorial orbits into three-dimensional ones play predominant role in the formation of these shell structures.

Weak Matrix Elements and |V_cb| in New Formulation of Heavy Quark Effective Field Theory

description: The heavy quark effective field theory (HQEFT) containing both effective `quark fields' and `antiquark fields' is investigated in detail. By integrating out (but not neglecting) the effective antiquark fields, we present a new formulation of effective theory which differs from the usual heavy quark effective theory (HQET) and exhibits valuable features because of the inclusion of the contributions from the antiquark fields. Matrix elements of vector and axial vector heavy quark currents between pseudoscalar and vector mesons containing a heavy quark (b or c) are then evaluated systematically up to the order of $1/m^2_Q$ and parameterized by a set of universal form factors. With a consistent normalization condition between the effective heavy hadron states, the form factors at zero recoil are related to the ground state meson masses, which enables us to estimate the values of form factors at zero recoil. In particular, the Luke's theorem comes out automatically in the new formulation of HQEFT without the need of imposing the equation of motion $iv\cdot D Q^{+}_{v} =0$. Consequently, the differential decay rates of both $B\to D^{\ast}lν$ and $B\to D lν$ do not receive $1/m_{Q}$ order corrections at zero recoil, which is not the case in the usual HQET. Thus we quote that the Cabibbo-Kobayashi-Maskawa matrix element $| V_{cb}|$ can nicely be extracted from either of these two exclusive semileptonic decays at the order of $1/m^2_Q$. Our estimates for $|V_{cb}|$ are presented.

description: Out-of-equilibrium, non-perturbative, quantum effects significantly modify the standard picture of inflation in a wide class of models including new, natural, and hybrid inflation. We find that the quantum evolution of a single real inflaton field may be modeled by a classical theory of two homogeneous scalar fields. We briefly discuss the important observational consequences that are expected to result.

description: Recently measured high precision data of fusion excitation function have enabled a detailed study on the effects of nuclear collective excitations on fusion reactions. Using such highly accurate data of the $^{16}$O + $^{144,148}$Sm reactions, we discuss the anharmonic properties of collective phonon excitations in $^{144,148}$Sm nuclei. It is shown that subbarrier fusion reactions are strongly affected by the anharmonic effects and thus offer an alternative method to extract the static quadrupole moments of phonon states in a spherical nucleus.

description: Pheidole kusnezovi, new name
Eriopheidole symbiotica Kusnezov 1952d ("1951"): 16. Combination with Pheidole by Brown 1973b: 180, creating an unresolved junior homonym of Pheidole symbiotica Wasmann 1909a: 515, now resolved with the new name kusnezovi.
types Inst. Miguel Lillo, Tucuman; Mus. Comp. Zool. Harvard.
Etymology Named after N. Kusnezov, Argentinean entomologist who discovered the species.
diagnosis A permanent, workerless social parasite of Pheidole obscurior. The queen is very small in size, with slender head and large eyes, mostly shiny body surface, subangular petiole in side view, and hexagonal postpetiolar node seen from above. Overall, it has not evolved any of the extreme parasitic traits of other socially parasitic Pheidole such as acutidens, argentina, and elecebra. measurements (mm) Queen: HW 0.64, HL 0.64, SL 0.78, EL 0.24, PW (not measured).
color Queen: appendages, anterior half of the head, and most of the sides of the mesosoma yellow; rest of head and body a contrasting light brown.
Range Known only from the type locality.
Biology Kusnezov's (1952a) field and laboratory research showed that Pheidole inquilina is a workerless inquiline of P. obscurior. He correctly pointed out that the queen represents an early stage of the kind of degenerative anatomy that characterizes ant inquilines in general.

description: We previously described a pig junction protein of M(r) 37,000 found in oral epithelium but not in epidermis, limited to suprabasal cells, and colocalizing by immunofluorescence with adherens junction proteins. A 1.1-kilobase pair cDNA of the 37-kDa protein yielded an open reading frame encoding a 323-amino acid protein of 35,852 Da, and Northern analysis demonstrated a band of 1.2 kilobases in tongue RNA. Secondary structure predictions indicate that the 37% identical 16-17-kDa N- and C-terminal domains from beta-sheet-rich barrels linked by a compact proline-rich segment. The protein is 72% identical in amino acid sequence and shares symmetrical two-domain structure with L-36, a lectin of unknown function from rat intestine, indicating that the 37-kDa protein is the porcine form of L-36. Of the homologous lactose binding lectins known, two others, invertebrate lectins, share this symmetrical structure. Expression of the C-terminal domain of the pig lectin in bacteria yields a lectin which binds lactosyl-Sepharose, and binding is inhibited by lactose. The expressed protein binds a glycoprotein of 120 kDa from pig tongue epithelium on Western blots, and this is also inhibited by lactose. The findings suggest that the lectin function may be involved in the assembly of adherens junctions.
Solar Neutrinos and Leptonic CP Violation

description: We examine the possibility of detecting effects of leptonic CP violation by precise measurement of the solar neutrinos within the framework of standard electroweak theory minimally extended to include neutrino masses and mixing. We prove a ``no-go theorem'' which states that effects of CP violating phase disappear in the nu_e survival probability to the leading order in electroweak interaction. The effects due to the next-to-leading order correction is estimated to be extremely small, effectively closing the door to the possibility we intended to pursue.

Analysis of the translational initiation region on the Euglena gracilis chloroplast ribulose-bisphosphate carboxylase/oxygenase (rbcL) messenger RNA
Creators: name: Spremulli, Linda L
name: Koo, Ja Seok

description: The chloroplast mRNAs from Euglena gracilis fall into two classes. One group of mRNAs from this organelle contains a Shine-Dalgarno sequence 5' to the start codon, while the other group of mRNAs does not have a conserved sequence signal in the 5'-untranslated region. To investigate the start signals for E. gracilis chloroplast mRNAs that do not carry a Shine-Dalgarno sequence, 90 S initiation complex formation has been studied using a series of transcripts carrying the wild-type translational start site of ribulose-bisphosphate carboxylase/ oxygenase (rbcL) or mutated derivatives of this site.

description: A novel method of color image enhancement is proposed, in which three or four color channels of the image are transformed to one channel 2-D grayscale image. This paper describes different models of such transformations in the RGB and other color models. Color image enhancement is achieved by enhancing first the transformed grayscale image and, then, transforming back the grayscale image into the colors. The color image enhancement is done on the transformed 2-D grayscale image rather than on the color image. New algorithms of color image enhancement are described in both frequency and time domains. The enhancement by this novel method shows good results. The enhancement of the image is measured with respect to the metric referred to as the Color Enhancement Measure Estimation (CEME).

East Austin : a socio-historical view of a segregated community

description: The prevalence of segregation in Austin, Texas, kindled my personal interest in the subject. While a student in the city, I was amazed at the high degree of segregation in Austin. With the exception of Blacks recruited from other geographic areas for positions at the state university and the small number of professionals working in state government, most Blacks live in one section of the city. In other words, the native Black population of Austin is isolated in basically one community. The segregation of Black Austinites into a single community evoked my curiosity. How did the Blacks in Austin come to live in one segregated neighborhood? Pockets of segregated Black communities are common in American cities but, in Austin, Blacks are isolated on a specific side of town. After questioning long-time residents of the city, I found that in the early history of Austin, Black communities were located on all sides of the city. If these communities had continued to prosper, one would expect to find thriving Black communities in most sections of the city. This assumption, however, does not prove true and this study attempts to uncover the reasons for its fallacy
Effect of anomalous tbW vertex on decay-lepton distributions in e+e- -> t tbar and CP-violating asymmetries

description: We obtain analytic expressions for the energy and polar-angle double differential distributions of a secondary lepton l+ (l-) arising from the decay of t (tbar) in e+e- -> t tbar with an anomalous tbW decay vertex. We also obtain analytic expressions for the various differential cross sections with the lepton energy integrated over. In this case, we find that the angular distributions of the secondary lepton do not depend on the anomalous coupling in the decay, regardless of possible anomalous couplings occurring in the production amplitude for e+e- -> t tbar. Our study includes the effect of longitudinal e- and e+ beam polarization. We also study the lepton energy and beam polarization dependence of certain CP-violating lepton angular asymmetries arising from an anomalous tbW decay vertex and compare them with the asymmetries arising due to CP violation in the production process due to the top electric or weak dipole moment.
