description: The diterpene ester promoter of mouse skin tumors, 12-O-tetradecanoylphorbol-13-acetate (TPA), efficiently induces Epstein-Barr virus (EBV)-associated DNA polymerase (DNA nucleotidyltransferase) activity in the EBV-producing lymphoblastoid cell line, P3HR-1. With the use of intervent dilution chromatography followed by sequential DEAE-cellulose and phosphocellulose column chromatography, the virus-associated enzyme has been isolated and purified 300-fold. The partially purified EBV DNA polymerase activity could be distinguished from cellular polymerases by its activation with salt and its degree of sensitivity to N-ethylmaleimide and phosphonoacetic acid. The enzyme showed maximum activity for copying activated calf thymus DNA in the presence of 100 mM ammonium sulfate. In the absence of salt, the enzyme utilized with high efficiency deoxyoligomer-homopolymer templates, but failed to copy poly(rA) . oligo(dT)10 and oligo(dT)10, showing that the enzyme had properties distinct from DNA polymerase gamma, reverse transcriptase, and terminal deoxynucleotidyltransferase. The partially purified enzyme is strongly inhibited by acyclovir triphosphate and thus has properties similar to herpes simplex virus DNA polymerase.

description: We report an experimental study of quantum conductivity corrections for two-dimensional electron gas in a GaAs/InGaAs/GaAs single and double quantum wells in a wide temperature range (1.8-100) K. We perform a comparison of our experimental data for the longitudinal conductivity at zero magnetic field to the theory of interaction-induced corrections to th transport coefficients. In the temperature range from 10 K up to (45-60) K, wich covers the ballistic interaction regimes for our samples, a rather good agreement between the theory and our experimental results has been found.
Energy Dependence of the NN t-matrix in the Optical Potential for Elastic Nucleon-Nucleus Scattering

description: The influence of the energy dependence of the free NN t-matrix on the optical potential of nucleon-nucleus elastic scattering is investigated within the context of a full-folding model based on the impulse approximation. The treatment of the pole structure of the NN t-matrix, which has to be taken into account when integrating to negative energies is described in detail. We calculate proton-nucleus elastic scattering observables for $^{16}$O, $^{40}$Ca, and $^{208}$Pb between 65 and 200 MeV laboratory energy and study the effect of the energy dependence of the NN t-matrix. We compare this result with experiment and with calculations where the center-of-mass energy of the NN t-matrix is fixed at half the projectile energy. It is found that around 200 MeV the fixed energy approximation is a very good representation of the full calculation, however deviations occur when going to lower energies (65 MeV).

New approach for studying macromolecular-ligand binding. Determination of the dissociation constant for macromolecule-bound ligand by gel filtration.
Creators: name: Zeeberg, Barry
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1980

description: A graph is presented which permits facile determination of the dissociation constant constant for a macromolecule . ligand complex from gel filtration results; it can be used without a detailed understanding of the remainder of the text. When a solution of macromolecules and radioactive ligand is subjected to gel filtrations, the amount of ligand associated with the eluted macromolecule is easily measured. This quantity is then used for obtaining the corresponding dissociation constant from the graph. Values given in the graph had been determined from an equation, which is presented in the text, by means of a program which is run on a programmable calculator (Texas Instruments SR-52). It is also demonstrated how the validity of dissociation constants so obtained can be checked independently by means of a second calculation. A modification of these procedures permits determination of the dissociation constant for those situations where there is moderate dilution of the eluted sample relative to that applied to the gel filtration column, and the graph incorporates results from such calculations. The successful application of the present approach to the determination of the dissociation constants for a tubulin . [3H]GDP complex is described. Also, the potential importance of the present approach relative to other techniques for dissociation constant determination is discussed.
The modulation effect for supersymmetric dark matter detection with asymmetric velocity dispersion

description: The detection of the theoretically expected dark matter is central to particle physics cosmology. Current fashionable supersymmetric models provide a natural dark matter candidate which is the lightest supersymmetric particle (LSP). Such models combined with fairly well understood physics like the quark substructure of the nucleon and the nuclear form factor and the spin response function of the nucleus, permit the evaluation of the event rate for LSP-nucleus elastic scattering. The thus obtained event rates are, however, very low or even undetectable. So it is imperative to exploit the modulation effect, i.e. the dependence of the event rate on the earth's annual motion. In this review we study such a modulation effect in directional and undirectional experiments. We calculate both the differential and the total rates using symmetric as well as asymmetric velocity distributions. We find that in the symmetric case the modulation amplitude is small, less than 0.07. There exist, however, regions of the phase space and experimental conditions such that the effect can become larger. The inclusion of asymmetry, with a realistic enhanced velocity dispersion in the galactocentric direction, yields the bonus of an enhanced modulation effect, with an amplitude which for certain parameters can become as large as 0.46.

Two Kinds of Dynamic Behavior in a Quiescent Prominence Observed by the NVST

description: We present high-resolution observations of two kinds of dynamic behavior in a quiescent prominence using the New Vacuum Solar Telescope, i.e., Kelvin-Helmholtz instabilities (KHIs) and small-scale oscillations. The KHIs were identified as rapidly developed vortex-like structures with counter-clockwise/clockwise rotations in the Ha red-wing images at +0.3 A, which were produced by the strong shear-flows motions on the surface/interface of prominence plumes. The KHI growth rates are estimated to be about 0.0135 +(-)0.0004 and 0.0138 +(-) 0.0004. Our observational results further suggest that the shear velocities (i.e, supersonic) of the mass flows are fast enough to produce the strong deformation of the boundary and overcome the restraining surface tension force. This flow-driven instability might play a significant role in the process of plasma transfer in solar prominences. The small-scale oscillations perpendicular to the prominence threads are observed in the Ha line-center images. The oscillatory periods changed non-monotonically and showed two changing patterns, in which one firstly decreased slowly and then it changed to increase, while the other grew fast at the beginning and then it changed to decrease. Both of these two thread oscillations with changing periods were observed to be unstable for an entire cycle, and they were local in nature. All our findings indicate that the small-scale thread oscillations could be magnetohydrodynamic waves in the solar corona.

description: We study the approach to equilibrium of a Bose gas to a superfluid state. We point out that dynamic scaling, characteristic of far from equilibrium phase-ordering systems, should hold. We stress the importance of a non-dissipative Josephson precession term in driving the system to a new universality class. A model of coarsening in dimension $d=2$, involving a quench between two temperatures below the equilibrium superfluid transition temperature ($T_c$), is exactly solved and demonstrates the relevance of the Josephson term. Numerical results on quenches from above $T_c$ in $d=2,3$ provide evidence for the scaling picture postulated.

Proton permeability of sarcoplasmic reticulum vesicles.

name: Meissner, G
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1980

description: The proton permeability of rabbit skeletal muscle sarcoplasmic reticulum vesicles was investigated by means of membrane potential measurements. Diffusion potentials were generated in sarcoplasmic reticulum vesicles, rat liver microsomes, and sarcoplasmic reticulum phospholipid vesicles by transferring vesicles from low to high pH. Potentials were measured using the voltage-sensitive fluorescent dye 3,3'-dipentyl-2,2'-oxacarbocyanine. Diffusion potentials were generated readily in sarcoplasmic reticulum vesicles using H+ gradients. Generation of a similar potential in phospholipid vesicles or liver microsomes required the presence of an uncoupler of oxidative phosphorylation. H+ and K+ gradient competition experiments indicated that both K+,Na+-permeable and -impermeable sarcoplasmic reticulum vesicles were permeable to H+. These studies suggested that a mechanism of H+ transport exists in sarcoplasmic reticulum that is independent of the K,Na channel, and that transient or steady state membrane potentials may be effected by the movement of H+.

description: P systems are computing conceptual computing devices that are at least as powerful as Turing machines. However, until recently it was not known how one can encode any recursive function as a P~system. Here we propose a new encoding of recursive as P~systems with graph-like structure, which is the main difference with previous documented attempts. The consequence of this and other such efforts is that they provide a solid ground for the implementation of real programming languages in existing hardware.

description: The mass of dihyperon with spin, parity $J^π=0^{+}$ and isospin $I = 0$ is calculated in the framework of Chiral colour dielectric model. The wave function of the dihyperon is expressed as a product of two colour-singlet baryon clusters. Thus the quark wave functions within the cluster are antisymmetric. Appropriate operators are then used to antisymmetrize inter-cluster quark wave functions. The radial part of the quark wavefunctions are obtained by solving the the quark and dielectric field equations of motion obtained in the Colour dielectric model. The mass of the dihyperon is computed by including the colour magnetic energy as well as the energy due to meson interaction. The recoil correction to the dihyperon mass is incorporated by Peierls-Yoccoz technique. We find that the mass of the dihyperon is smaller than the $Λ-Λ$ threshold by over 100 MeV. The implications of our results on the present day relativistic heavy ion experiments is discussed.

description: Using two-temperature model coupled with modified time-dependent Ginzburg-Landau equation we calculate the delay time $τ_d$ in appearance of growing normal domain in the current-biased superconducting strip after absorption of the single photon. We demonstrate that $τ_d$ depends on the place in the strip where photon is absorbed and monotonically decreases with increasing of the current. We argue, that the variation of $τ_d$ (timing jitter), connected either with position-dependent response or Fano fluctuations could be as small as the lowest relaxation time of the superconducting order parameter $\sim \hbar/k_BT_c$ ($T_c$ is the critical temperature of the superconductor) when the current approaches the depairing current.

Use of immunoglobulin-loaded protein A-bearing staphylococci as a primary solid phase immunoadsorbent in radioimmunoassay.
Creators: name: O'Keefe, E
name: Vennett, V
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Protein A-bearing formalinized heat-inactivated Staphylococcus aureus bind rabbit 125I-IgG with high capacity of IgG for antigen. The affinity of immobilized IgG for antigen is equal to the affinity of soluble antibody, and the capacity for antigen approximates the capacity of soluble antibody for antigen. 125I-IgG bound to high affinity sites on bacteria is not substantially displaced in the presence of human serum after 4 h at 4 degrees C, but rabbit immunoglobulin can displace bound rabbit IgG. Protein A-bearing bacteria which have adsorbed IgG free from protease activity in antiserum provide a stable, sensitive, primary solid phase adsorbent with unique features for radioimmunoassay. Sedimentation characteristics of bacteria permit facile separation of bound from free ligand by centrifugation of the primary antibody. Immunoglobulin-loaded staphylococci can adsorb ligand from serum, simultaneously purifying and concentrating ligands for measurement in a single subsequent step. Immunoglobulin-bearing bacteria can be used directly in biological fluids containing immunoglobulin, such as serum and culture media. Improved economy of staphylococci, low nonspecific binding, high functional capacity, stability, and unique characteristics of radioimmunoassay using immunoglobulin-loaded staphylococci compare favorably with conventional solid phase adsorbents.

description: The interaction of Escherichia coli glutamine synthetase with the adenosine 5'-triphosphate analogue, 5'-p-fluorosulfonylbenzoyladenosine (5'-FSO2BzAdo), has been studied. This interaction results in the covalent attachment of the 5'-FSO2BzAdo to the enzyme with concomitant loss of catalytic activity. Although adenine nucleotides interact with glutamine synthetase at three distinct sites--a noncovalent AMP effector site, a regulatory site of covalent adenylylation, and the catalytic ATP/ADP binding site--our studies suggest that reaction with 5'-FSO2BzAdo occurs only at the active center. When glutamine synthetase was incubated with 5'-FSO2BzAdo, the decrease in catalytic activity obeyed pseudo-first order kinetics. The plot of the observed rate constant of inactivation versus the concentration of 5'-FSO2BzAdo was hyperbolic, consistent with reversible binding of the analogue to the enzyme prior to covalent attachment. Protection against inactivation was afforded by ATP and ADP; L-glutamate did not protect the enzyme against inactivation, but rather enhanced the rate of inactivation, consistent with the observations of others (Timmons, R. B., Rhee, S. G., Luterman, D. L., and Chock, P. B. (1974) Biochemistry 13, 4479-4485) that there is synergism in the binding of the two substrates to the enzyme. The incorporation of approximately 1.09 mol of the 5'-FSO2BzAdo/mol of glutamine synthetase subunit resulted in the total loss of enzymatic activity. The results suggest that 5'-FSO2BzAdo occupies the ATP binding site at the active center of glutamine synthetase and binds covalently to an amino acid residue nearby.

description: Electron capture times in a separate confinement quantum well (QW) structure with finite electron density are calculated for electron-electron (e-e) and electron-polar optic phonon (e-pop) scattering. We find that the capture time oscillates as function of the QW width for both processes with the same period, but with very different amplitudes. For an electron density of 10^11 cm^-2 the e-e capture time is 10-1000 times larger than the e-pop capture time except for QW widths near the resonance minima, where it is only 2-3 times larger. With increasing electron density the e-e capture time decreases and near the resonance becomes smaller than the e-pop capture time. Our e-e capture time values are two-to-three orders of magnitude larger than previous results of Blom et al. [Appl. Phys. Lett. 62, 1490 (1993)]. The role of the e-e capture in QW lasers is therefore readdressed.

description: Post impingement morphology and dynamics of water droplets on convex cylindrical surfaces has been explored experimentally. Droplet impact and post-impact feature studies have been conducted on hydrophillic and superhydrophobic cylindrical surfaces. Effects of the impact Weber number and target-to-drop diameter ratio have been studied. The post-impact hydrodynamics have been quantified using the wetting fraction, the spreading factor and nondimensional film thickness at the north pole of the target. The observations reveal that the wetting fraction and spread factor increases with an increase in the impact We and decrease in the target to drop diameter ratio. An opposite trend is noted for nondimensional film thickness at the targets north pole. It is also deduced that the spread factor is independent of the target wettability. The lamella dynamics post spreading has also been observed to be a strong function of the wettability, impact We and the diameter ratio. An analytical expression for temporal evolution of film thickness at north pole of the cylinderical target is derieved. Another theoretical model based on energy conservation for predicting the maximum wetting fraction for variant cylindrical targets in terms of the governing We and Capillary number and the experimental measurements are in good agreement with the theoretical predictions.

description: Androgen-binding protein (ABP) was purified from caput epididymis of the rat by sequential chromatography on DEAE-Sepharose, hydroxylapatite, dihydrotestosterone-17 beta-hemisuccinyl-1,6-diaminohexane-Sepharose, and Sephadex G-150. The final product migrated as a single band corresponding to a peak of protein-bound [3H]dihydrotestosterone on polyacrylamide gel electrophoresis. A molecular weight of 100,000 was estimated by sedimentation equilibrium. On sodium dodecyl sulfate-polyacrylamide gel electrophoresis, subunits of Mr = 47,000 and 41,000 were observed. Amino acid analysis indicated ABP to be rich in leucine while nonpolar aminoacids totaled only 51%. Its carbohydrate content is 25%. Antibodies to purified ABP were raised in a rabbit and evaluated by immunodiffusion, immunoelectrophoresis, binding inhibition, radioimmunoassay, and immunocytochemistry. Immunoperoxidase staining localized ABP in the basal and adluminal regions of seminiferous tubules of rat testis and in secretory granules of cultured Sertoli cells. In principal cells of caput epididymis, ABP is concentrated in the supranuclear region known to contain morphological specializations for absorption. These immunocytochemical results confirm that ABP synthesized and secreted by Sertoli cells in the testis is transported to the epididymal duct via testicular fluid and is taken up by epithelial cells of the proximal segments.

description: The 1+1 dimensional abelian Higgs model with fermions is a toy model for the theory of electroweak baryogenesis. We study the dynamics of the model with axially coupled fermions in real-time. The model is defined on a spacetime lattice to preserve gauge invariance and to obtain numerical stability in a simple way. We take into account the phenomenon of lattice fermion doubling. The dynamics is approximated by treating the inhomogeneous Bose fields classically, which is justified in a large N_f approximation. The back reaction on the Bose fields due to fermion field fluctuations is calculated using a mode function expansion. We discuss and present numerical results for the response of fermions to sphaleron transitions, the renormalizability of the effective equations of motion and non-perturbative dynamics in the framework of non-equilibrium quantum field theory. The long-time behaviour of the system is discussed and we speculate about applications to finite density calculations.

Calcium transport and monovalent cation and proton fluxes in sarcoplasmic reticulum vesicles

description: ATP-dependent Ca2+ uptake by rabbit skeletal muscle sarcoplasmic reticulum vesicles has been studied in the presence and absence of artificially generated pH gradients and membrane potentials. H+ and K+ diffusion potentials were generated via the H+ and K,Na channels of sarcoplasmic reticulum by transfer of vesicles from low to high pH, or from high to low K+. Membrane potentials were measured using the voltage-sensitive fluorescent dye 3,3'-dipentyl-2,2'-oxacarbocyanine. The initial rate of Ca2+ uptake was found to be increased in the presence of a pH gradient and membrane potential (negative inside). In turn, the rates of decay of K+- or H+-induced membrane potentials were accelerated during Ca2+ transport, suggesting that active Ca2+ uptake stimulated the release of K+ and H+ from the vesicles. The ratio of K+ (or H+) release to Ca2+ transport was near two. Release of K+ did not appear to be directly catalyzed by the Ca2+-ATPase. Evidence against a directly coupled ATP-mediated 2 K+-Ca2+ or K+-Ca2+ exchange reaction was that (i) similar results were obtained when K+ was substituted by Na+ or by organic cations which could rapidly permeate through the channel of K+,Na+-permeable vesicles and (ii) Ca2+ transport did not result in an equivalent release of 86Rb+ or 22Na+ from K+,Na+-impermeable vesicles. These studies are in support of an electrogenic Ca2+ transport system in sarcoplasmic reticulum. The results further suggest that during Ca2+ transport development of a membrane potential (positive inside) is likely nullified by the countermovement of the permeant cations K+, Na+, and H+.

description: The double and single differential cross-sections with respect to positron and electron energies as well as the total cross-section of triplet production in the laboratory frame are calculated numerically in order to develop a Monte Carlo code for modelling electron-photon cascades in a soft photon field. To avoid numerical integration irregularities of the integrands, which are inherent to problems of this type, we have used suitable substitutions in combination with a modern powerful program code Mathematica allowing one to achieve reliable higher-precission results. The results obtained for the total cross-section closely agree with others estimated analytically or by a different numerical approach. The results for the double and single differential cross-sections turn out to be somewhat different from some reported recently. The mean energy of the produced particles, as a function of the characteristic collisional parameter (the electron rest frame photon energy), is calculated and approximated by an analytical expression that revises other known approximations over a wide range of values of the argument. The primary-electron energy loss rate due to triplet pair production is shown to prevail over the inverse Compton scattering loss rate at several ($\sim$2) orders of magnitude higher interaction energy than that predicted formerly.

description: Solar active regions (ARs) that produce major flares typically exhibit strong plasma shear flows around photospheric magnetic polarity inversion lines (MPILs). It is therefore important to quantitatively measure such photospheric shear flows in ARs for a better understanding of their relation to flare occurrence. Photospheric flow fields were determined by applying the Differential Affine Velocity Estimator for Vector Magnetograms (DAVE4VM) method to a large data set of 2,548 co-aligned pairs of AR vector magnetograms with 12-min separation over the period 2012-2016. From each AR flow-field map, three shear-flow parameters were derived corresponding to the mean (), maximum (S_max) and integral (S_sum) shear-flow speeds along strong-gradient, strong-field MPIL segments. We calculated flaring rates within 24 hr as a function of each shear-flow parameter, and also investigated the relation between the parameters and the waiting time (τ) until the next major flare (class M1.0 or above) after the parameter observation. In general, it is found that the larger S_sum an AR has, the more likely it is for the AR to produce flares within 24 hr. It is also found that among ARs which produce major flares, if one has a larger value of S_sum then τ generally gets shorter. These results suggest that large ARs with widespread and/or strong shear flows along MPILs tend to not only be more flare productive, but also produce major flares within 24 hr or less.

Evidence for two types of rat liver microsomes with differing permeability to glucose and other small molecules

name: Meissner, G

Year: 1981

description: Radioisotope flux measurements using Millipore filtration revealed two populations of rat liver microsomes designated type A and B. Type A and B vesicle are similar in that both are essentially impermeable to sucrose yet permeable to Cl-. About 70% of the microsome (type A) are permeable to D-glucose, L-glucose, 2-deoxy-D-glucose, D-mannose, D-mannitol, uridine, glycine, L-leucine, choline+, Tris+, Rb+, K+, and Na+. Other solutes such as D-gluconate-, D-glucosamine+, N-acetyl-D-glucosamine, L-glutamate-, L-lysine+, sulfate2-, oxalate2-, and phosphate anions transverse type A vesicles with an intermediate rate. All of the above solutes except Cl- pass with a comparatively slow rate the remaining 30% type B vesicles. Both type A and B microsomes are relatively impermeable to glucose 6-phosphate and related monophosphates. Membrane potential measurements using liver microsomes and control membrane vesicles derived from rabbit skeletal muscle sarcoplasmic reticulum indicated that type A liver microsomes, despite being permeable to K+ and Na+, either lack or contain only a small number of highly conducting K+ and Na+ structures, such as the K,Na channel of sarcoplasmic reticulum. Treatment with the anion transport inhibitor 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid lowered the permeability of type A vesicles to several uncharged and negatively charged solutes including D-glucose and gluconate-. These results suggest that a large fraction of liver microsomes is rendered permeable to various biologically relevant solutes and ions, perhaps through the presence of one or more channels with a maximal diameter of approximately 7-8 A which select(s) against solutes on the basis of their size and charge.

description: We present an implementation of the Hall term in the non-ideal magnetohydrodynamics equations into the adaptive-mesh-refinement code RAMSES to study its impact on star formation. Recent works show that the Hall effect heavily influences the regulation of the angular momentum in collapsing dense cores, strengthening or weakening the magnetic braking. Our method consists of a modification of the two-dimensional constrained transport scheme. Our scheme shows convergence of second-order in space and the frequency of the propagation of whistler waves is accurate. We confirm previous results, namely that during the collapse, the Hall effect generates a rotation of the fluid with a direction in the mid-plane that depends on the sign of the Hall resistivity, while counter-rotating envelopes develop on each side of the mid-plane. However, we find that the predictability of our numerical results is severely limited. The angular momentum is not conserved in any of our dense core-collapse simulations with the Hall effect: a large amount of angular momentum is generated within the first Larson core, a few hundred years after its formation, without compensation by the surrounding gas. This issue is not mentioned in previous studies and may be correlated to the formation of the accretion shock on the Larson core. We expect that this numerical effect could be a serious issue in star formation simulations.
