description: Recent cosmological observations strongly suggest that the universe is dominated by an unknown form of energy with negative pressure. Why is this dark energy density of order the critical density today? We propose that the dark energy has periodically dominated in the past so that its preponderance today is natural. We illustrate this paradigm with a model potential and show that its predictions are consistent with all observations.

Range A common species in Costa Rica from Meseta Central northward, up to 1500 m (Longino 1997).
Biology According to Longino (1997), indagatrix occurs in moist to wet forests, both on the ground and in the canopy, and forages both day and night. It is equally flexible in nesting sites, with colonies having been found variously in and under dead wood on the ground, and in one case each, under accreted soil on the side of a tree trunk and in a hollow live stem. Winged males have been found in nests in January and March.

Receptor accessory factor enhances specific DNA binding of androgen and glucocorticoid receptors

description: Protein-protein interactions are common among transcriptional activators and may have important consequences for gene regulation. Using the mobility shift assay, we have identified a factor that enhances specific DNA binding of truncated rat androgen (AR) and glucocorticoid (GR) receptors by 25- and 6-fold, respectively, through the formation of heteromeric complexes. This factor, designated receptor accessory factor, or RAF, also potentiates DNA binding of full-length human GR. RAF is temperature and trypsin sensitive and is present in a variety of cultured mammalian cells. By gel filtration RAF has a predicted molecular mass of 130 kDa. RAF enhancement of AR-DNA binding is optimal with androgen response element DNA. RAF appears to interact directly with AR because 1) deoxycholate, which interferes with protein-protein but not protein-DNA interactions, prevents RAF.AR.DNA complex formation, 2) RAF activity is recovered from an androgen response element DNA affinity column only in the presence of AR, and 3) RAF increases the size of an AR.DNA complex by gel filtration. Mutagenesis of truncated AR fragments indicates that a region in the NH2-terminal domain is required for RAF to enhance AR-DNA binding. The interaction of RAF with AR and GR suggests that RAF might influence the ability of these nuclear receptors to activate transcription.

description: To improve the census of the Upper Sco association (~11 Myr, ~145 pc), we have identified candidate members using parallaxes, proper motions, and color-magnitude diagrams from several wide-field imaging surveys and have obtained optical and infrared spectra of several hundred candidates to measure their spectral types and assess their membership. We also have performed spectroscopy on a smaller sample of previously known or suspected members to refine their spectral types and evidence of membership. We have classified 530 targets as members of Upper Sco, 377 of which lack previous spectroscopy. Our new compilation of all known members of the association contains 1631 objects. Although the census of Upper Sco has expanded significantly over the last decade, there remain hundreds of candidates that lack spectroscopy. The precise parallaxes and proper motions from the second data release of Gaia should extend down to substellar masses in Upper Sco, which will greatly facilitate the identification of the undiscovered members.

description: We present detailed results of a diagrammatic calculation of the leading two-loop QCD corrections to the masses of the neutral CP-even Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM). The two-loop corrections are incorporated into the full diagrammatic one-loop result and supplemented with refinement terms that take into account leading electroweak two-loop and higher-order QCD contributions. The dependence of the results for the Higgs-boson masses on the various MSSM parameters is analyzed in detail, with a particular focus on the part of the parameter space accessible at LEP2 and the upgraded Tevatron. For the mass of the lightest Higgs boson, m_h, a parameter scan has been performed, yielding an upper limit on m_h which depends only on tan(beta). The results for the Higgs-boson masses are compared with results obtained by renormalization group methods. Good agreement is found in the case of vanishing mixing in the scalar quark sector, while sizable deviations occur if squark mixing is taken into account.

Specific contribution of different phospholipid surfaces to the activation of prothrombin by the fully assembled prothrombinase

description: This paper addresses, in thermodynamic and kinetic terms, the reasons for the acidic lipid specificity of the human prothrombinase complex. We obtained, from the measured lipid titrations of the initial rates of prothrombin activation, the empirical binding constants for prothrombinase assembly on different membranes. These favored assembly on phosphatidylserine (PS)- as opposed to phosphatidylglycerol (PG)-containing membranes. In addition, we have used full time courses of prothrombin activation, in conjunction with a calculation of the equilibrium distribution of factor Xa between four enzymatic forms, to obtain the intrinsic kinetic constants of the prothrombinase assembled on PS- or PG-containing membranes. The resulting values of kcat, Km, and kcat/Km increased as acidic lipid content increased, and kcat/Km reached a plateau at 12 mol % PS and 50 mol % PG. Using the measured assembly and kinetic constants, the observed shapes of the phospholipid titration curves of human prothrombin activation were interpreted. We conclude that the difference in activity of prothrombinase assembled on PS- versus PG-containing membranes results both from the different binding properties of factors Xa and Va to these surfaces and from the different intrinsic activities of the prothrombinase when assembled on different membranes.

description: We have applied the Meson Cloud Model to calculate inclusive momentum spectra of pions and kaons produced in high energy proton-proton and proton-nucleus collisions. For the first time these data are used to constrain the cloud cut-off parameters. We show that it is possible to obtain a reasonable description of data, especially the large $x_F$ ($x_F \geq 0.2$) part of the spectrum and at the same time describe (partially) the E866 data on $\bar d - \bar u$ and $\bar d / \bar u$. We also discuss the relative strength of the $πN$ and $πΔ$ vertices. We find out that the corresponding cut-off parameters should be both soft and should not differ by more than 200 MeV from each other. An additional source (other than the meson cloud) of sea antiquark asymmetry, seems to be necessary to completely explain the data. A first extension of the MCM to proton nucleus collisions is discussed.

description: Radio images of the Galactic Center supermassive black hole, Sagittarius A* (Sgr A*), are dominated by interstellar scattering. Previous studies of Sgr A* have adopted an anisotropic Gaussian model for both the intrinsic source and the scattering, and they have extrapolated the scattering using a purely $λ^2$ scaling to estimate intrinsic properties. However, physically motivated source and scattering models break all three of these assumptions. They also predict that refractive scattering effects will be significant, which have been ignored in standard model fitting procedures. We analyze radio observations of Sgr A* using a physically motivated scattering model, and we develop a prescription to incorporate refractive scattering uncertainties when model fitting. We show that an anisotropic Gaussian scattering kernel is an excellent approximation for Sgr A* at wavelengths longer than 1cm, with an angular size of $(1.380 \pm 0.013) λ_{\rm cm}^2\,{\rm mas}$ along the major axis, $(0.703 \pm 0.013) λ_{\rm cm}^2\,{\rm mas}$ along the minor axis, and a position angle of $81.9^\circ \pm 0.2^\circ$. We estimate that the turbulent dissipation scale is at least $600\,{\rm km}$, with tentative support for $r_{\rm in} = 800 \pm 200\,{\rm km}$, suggesting that the ion Larmor radius defines the dissipation scale. We find that the power-law index for density fluctuations in the scattering material is $β< 3.47$, shallower than expected for a Kolmogorov spectrum ($β=11/3$), and we estimate $β= 3.38^{+0.08}_{-0.04}$ in the case of $r_{\rm in} = 800\,{\rm km}$. We find that the intrinsic structure of Sgr A* is nearly isotropic over wavelengths from 1.3mm to 1.3cm, with a size that is roughly proportional to wavelength. We discuss implications for models of Sgr A*, for theories of interstellar turbulence, and for imaging Sgr A* with the Event Horizon Telescope.

description: Infection of Spodoptera frugiperda Sf9 insect cells with recombinant human androgen receptor (AR) baculovirus results in expression of a 118-kDa phosphoprotein that displays high affinity androgen binding and androgen-dependent targeting to the nucleus. Using the DNA mobility shift assay, specific in vitro binding of full-length AR to androgen response element DNA (ARE) requires intracellular hormone exposure. The ability of a variety of steroids to induce ARE binding paralleled their transcriptional potential. Certain antihormones, cyproterone acetate and RU486, promote ARE binding, but a pure antiandrogen, hydroxyflutamide, inhibits AR binding to ARE DNA. AR dimerization requires incubation of recombinant baculovirus-infected insect cells with androgen, but only when one or both components of the dimer contain the NH2-terminal domain. Based on the intensities of ARE binding and lack of binding to an ARE half-site, it appears that, unlike the glucocorticoid receptor, AR binds DNA primarily as a dimer. Thus, full-length baculovirus-expressed AR requires intracellular hormone exposure for dimerization and ARE binding to overcome inhibition imposed by the AR NH2-terminal domain. Antihormones with agonist activity promote dimerization and ARE binding, while a pure antiandrogen blocks AR DNA binding. It is concluded that intramolecular interactions between the NH2-terminal and steroid-binding domains are regulated by the specificity of hormone binding and modulate receptor dimerization and DNA binding.

Thermal conductivity reduction by acoustic Mie resonance in nanoparticles

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We evaluate the impact of acoustic Mie resonance in nanoparticles on the thermal conductivity of semiconductor and polymer composites. By appropriately choosing the bulk modulus and density, and selecting the size of the nanoparticle to align the Mie resonances with the dominant portion of the thermal conductivity spectrum, we show that large reductions in thermal conductivity are achievable with dilute concentrations of nanoparticles. In semiconductor alloys, where the spectral thermal conductivity is known, our model can explain the steep reductions in thermal conductivity observed previously. However, the results of our effort to evaluate acoustic Mie resonance in polymer composites are inconclusive due to uncertainties in the spectral thermal conductivity. Acoustic Mie resonances can be useful for maximizing ZT for thermoelectric applications, since a dilute loading of nanoparticles can reduce thermal conductivity with minimal impact on electrical conductivity.
Strength, stability and three dimensional structure of mean motion resonances in the Solar System

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: In the framework of the circular restricted three body problem we show that the numerically computed strength SR(e,i,w) is a good indicator of the strength and width of the mean-motion resonances in the full space (e,i,w). We present a survey of strengths in the space (e,i) for typical interior and exterior resonances. The resonance strength is highly dependent on (e,i,w) except for exterior resonances of the type 1:k for which the dependence with (i,w) is softer. Such resonances are thus strong even for retrograde orbits. All other resonances are weaker at very-high eccentricities for w ~ 90 or 270 and 60 < i < 120. We explore the resonance structure in the space (a,i) by means of dynamical maps and we find structures similar to those of space (a,e).

description: We study zero temperature phase transitions in two classes of random quantum systems -the $q$-state quantum Potts and clock models. For models with purely ferromagnetic interactions in one dimension, we show that for strong randomness there is a second order transition with critical properties that can be determined exactly by use of an RG procedure. Somewhat surprisingly, the critical behaviour is completely independent of $q$ (for $2 \leq q < \infty$). For the $q > 4$ clock model, we suggest the existence of a novel multicritical point at intermediate randomness. We also consider the $T = 0$ transition from a paramagnet to a spin glass in an infinite range model. Assuming that the transition is second order, we solve for the critical behaviour and find $q$ independent exponents.

Structural and functional domains of the Drosophila ncd microtubule motor protein
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Nonclaret disjunctional (ncd) is a kinesin-related microtubule motor protein that is required for proper chromosome distribution in Drosophila. Despite its sequence similarity to kinesin heavy chain, ncd translocates with the opposite polarity as kinesin, toward microtubule minus ends. We have expressed different regions of the protein in bacteria and analyzed the proteins for function. Results indicate that ncd consists of three domains: a basic, proline-rich N-terminal "tail," a central alpha-helical coiled-coil stalk, and a C-terminal motor domain. The ncd N terminus proteins bundle microtubules in motility assays and show ATP-independent binding to microtubules in solution. Truncated proteins, lacking the tail but containing the pre-dieted motor domain and differing lengths of the stalk, did not support microtubule gliding in in vitro assays but showed microtubule-stimulated MgATPase activity in solution. Addition of a nonspecific N terminus to two of the truncated proteins restored directional gliding and rotation of microtubules in motility assays, demonstrating that these properties map to the predicted mechanochemical domain of ncd. Physical properties of the C terminus proteins indicate that the stalk region is important for dimerization and that the ncd protein probably exists and functions as a dimer

Temporal characteristics of quantal secretion of catecholamines from adrenal medullary cells
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Exocytotic release of vesicular catecholamine from individual bovine adrenal medullary cells was detected with carbon fiber microelectrodes. Release was elicited from cells permeabilized with 20 microM digitonin in extracellular solutions of pH 5.5, 7.4, or 8.2, and with 100 microM nicotine at pH 7.4. Release detected amperometrically with a 6-microns radius electrode and 1-micron cell-electrode spacing was qualitatively similar for each pH and stimulus. However, amperometric detection with smaller electrodes (radius = 1 micron), cyclic voltammetry, or increased cell-electrode spacing with the larger electrode all resulted in a severe reduction in size and frequency of spikes detected at pH 5.5. Thus, the existence of a steep catecholamine concentration gradient at the cell surface is necessary to cause dissociation of the vesicular matrix at low extracellular pH. At an extracellular pH of 7.4, the distribution of amperometric spike widths measured with a 1-micron cell-electrode spacing was found to be inconsistent with that predicted for diffusional dispersion during transport from the cell surface to the electrode. Both of these results agree with the hypotheses that the chromaffin vesicle matrix normally exists in an aggregated state that can be dissociated by a chemical driving force. Some of the spikes exhibit a pre-spike feature. These were present more often following permeabilization in acidic pH as opposed to more alkaline solutions, and were most prevalent following exposure to nicotine at pH 7.4. The variability in the occurrence of the pre-spike feature suggests it originates from free catecholamine within the vesicle, since the molar fraction bound by the vesicular matrix is regulated by the pH-dependent conformation and Ca(2+)-dependent binding affinity of chromogranin A, a major protein in the vesicle.

description: The lower and upper bounds on the neutrinoless double beta (0nu-2beta) decay rate are obtained, as functions of the parameters of neutrino oscillations and of the lightest neutrino mass. The constraints on these parameters from the search for the 0nu-2beta transition, as well as from the interpretation of solar and atmospheric neutrino data in terms of oscillations, can be conveniently represented in one unitarity triangle. This representation helps to clarify the cases when the 0nu-2beta rate is small; the crucial dependence on the scenarios assumed for solar neutrino oscillations and on the neutrino spectrum is emphasized. We consider hierarchical and non-hierarchical neutrino spectra, and discuss their interest in view of future searches of the 0nu-2beta decay.

description: We present a viable Monte Carlo determination of the scaling dimensions $Δ_Q$ of flux $Q$ Abelian monopoles through finite-size scaling analysis of the free energy to introduce the background field of classical Dirac monopole-antimonopole pair at critical points of three-dimensional lattice theories. We validate the method in free fermion theory, and by verifying the particle-vortex duality between the monopole scaling dimension at the inverse-XY fixed point and the charge scaling dimension at the XY fixed point. At the $O(2)$ Wilson-Fisher fixed point, we determine the critical exponents $Δ_1= 0.13(2)$, $Δ_2=0.29(1)$ and $Δ_3=0.47(2)$, which we find to be proportional to the finite-size critical spectrum of monopoles on square torus.

description: The alpha 5 beta 1 integrin mediates cell adhesion and migration on fibronectin, a glycoprotein critical for normal vertebrate embryonic development. Indirect evidence reported to date suggests that this receptor also functions in the deposition of fibronectin matrices. We used a molecular genetic approach to critically evaluate this role of alpha 5 beta 1 integrins. Mutant Chinese hamster ovary (CHO) cells deficient in alpha 5 integrin expression could not assemble a fibronectin matrix. Reconstituting alpha 5 beta 1 integrin expression by transfecting them with a full-length cDNA encoding the human alpha 5 chain completely restored fibronectin matrix assembly. CHO cells expressing an alpha 5 chain lacking the cytoplasmic domain also assembled a fibronectin matrix. Removing the cytoplasmic domain of alpha 5 appears to increase its activity in fibronectin matrix assembly. In addition to alpha 5 beta 1 integrin binding to fibronectin's RGD-containing domain, cells must bind with high affinity to fibronectin's amino-terminal 29-kDa matrix assembly domain to form a fibronectin matrix. Studies with the alpha 5-deficient CHO cells show that the expression of alpha 5 beta 1 integrin is also necessary for cells to bind fragments containing this distinct site in fibronectin and that a fibronectin matrix increases binding of the 29-kDa fragment. Thus, alpha 5 beta 1 integrins not only mediate cell adhesion to fibronectin, but also play an essential role in the assembly of a fibronectin matrix. This role includes direct binding to fibronectin and modulating a distinct binding event involving the interaction of fibronectin's amino-terminal matrix assembly domain with the cell surface.

description: The puckered surface of black phosphorus represents an ideal substrate for an unconventional arrangement of physisorbed species and the resulting specific two-dimensional chemistry of this system. This opens the way to investigate the chemical and physical properties of locally confined areas of black phosphorus without the necessity for further physical downscaling of the material. We have evaporated TCNQ on top of black phosphorus under over-saturation non-equilibrium conditions in vacuum. The evolution of linear density and height of droplets formed through oxidation during exposure to air was studied time-dependently by scanning-force microscopy. Our study suggests that the TCNQ molecules spontaneously arrange in a thin layer of the order of a few nm height, which, however, is fragmented with a periodicity of about 100 nm. It is shown that within the confined space separating the layer fragments the chemical dynamics of the oxidation process is remarkably different than on a bare black phosphorus surface.
Effect of magnetic field on electron neutrino sphere in pulsars

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

description: We study the neutrino interaction rates through charged as well as neutral current weak interactions in hot, dense magnetized matter. At densities near the neutrino sphere, matter in the presence of intense magnetic field is polarized and electrons and protons typically occupy the lowest Landau level. The weak interaction rates in such a situation are severally modified leading to a sizable change in neutrino opacity and consequently on the location of the neutrino sphere which also gets distorted. This has implications for pulsar velocity explanations.

description: Although the heterotrimeric Gi alpha subunit terminates in an apparent CXXX prenylation signal (CGLF), it is not modified by isoprenylation. To determine if the Gi alpha CXXX sequence can signal prenylation when placed at the carboxyl termini of normally prenylated proteins, we have characterized the processing and biological activity of chimeric oncogenic Ras proteins that terminate in the Gi alpha CXXX sequence (Ras/Gi alpha). Surprisingly, these chimeras were prenylated both in vivo and in vitro, demonstrated significant membrane association, exhibited transforming activity, and induced transcriptional transactivation from Ras-responsive elements. We then extended these studies to determine if, unlike the CC or CXC carboxyl-terminal sequences of other Rab proteins, the carboxyl-terminal CXXX sequences of the Ras-related Rab5 and Rab11 proteins represent conventional CXXX prenylation signals that can support Ras processing and transforming activity. Unexpectedly, these Ras/Rab chimeras were nonprenylated, were cytosolic, and lacked detectable transforming or transcriptional transactivation activity. Taken together, these results suggest that the context within which a CXXX sequence occurs may also critically control the modification of a protein by prenylation, and that the Rab5 and Rab11 carboxyl termini do not possess conventional CXXX sequences. Instead, their CCXX and CCXXX motifs may represent additional classes of protein prenylation signals.

description: The phase transitions between the XY, the dimer and the Haldane phases of the spin-1 bond-alternating XXZ chain are studied by the numerical diagonalization. We determine the phase diagram at $T=0$ and also identify the universality class with the level spectroscopy. We find that exactly on $Δ=0$ there is a Berezinskii-Kosterlitz-Thouless transition line which separates the XY and the Haldane phase and there exists a multicritical point of the XY, the dimer and the Haldane phases. We discuss that the critical properties of this model is of the 2-D Ashkin-Teller type reflecting the hidden $Z_2\times Z_2$ symmetry.

description: DNA photolyases catalyze the light-dependent repair of pyrimidine dimers in DNA. PW have utilized chemical modification and site-directed mutagenesis to probe the interactions involved in substrate recognition by the yeast photolyase Phr 1. Lys517was protected from reductive methylation in the presence of substrate, but not in its absence, and the specific and nonspecific association constants for substrate binding by Phr1(Lys517→Ala) were decreased 10-fold. These results establish a role for Lys517in substrate binding. Mutations at Ar507, Lys463, and Trp387reduced both the overall affinity for substrate and substrate discrimination.DNA photolyases catalyze the light-dependent repair of pyrimidine dimers in DNA.

description: We consider a chiral one-loop hedgehog soliton of the bosonized SU(2)$_f$ Nambu & Jona-Lasinio model which is embedded in a hot medium of constituent quarks. Energy and radius of the soliton are determined in self-consistent mean-field approximation. Quasi-classical corrections to the soliton energy are derived by means of the pushing and cranking approaches. The corresponding inertial parameters are evaluated. It is shown that the inertial mass is equivalent to the total internal energy of the soliton. Corrected nucleon and $Δ$ isobar masses are calculated in dependence on temperature and density of the medium. As a result of the self-consistently determined internal structure of the soliton the scaling between constituent quark mass, soliton mass and radius is noticeably disturbed.
