description: In this report we obtain explicit string-like solutions of equations of motion of massive heterotic supergravity recently obtained by Bergshoeff, Roo and Eyras. We also find consistent string source which can be embedded in these backgrounds when space-time dimension is greater than or equal to six.

description: We investigate the accuracy with which the reconnection electric field $E_M$ can be determined from in-situ plasma data. We study the magnetotail electron diffusion region observed by NASA's Magnetospheric Multiscale (MMS) on 2017-07-11 at 22:34 UT and focus on the very large errors in $E_M$ that result from errors in an $LMN$ boundary-normal coordinate system. We determine several $LMN$ coordinates for this MMS event using several different methods. We use these $M$ axes to estimate $E_M$. We find some consensus that the reconnection rate was roughly $E_M$=3.2 mV/m $\pm$ 0.06 mV/m, which corresponds to a normalized reconnection rate of $0.18\pm0.035$. Minimum variance analysis of the electron velocity (MVA-$v_e$), MVA of $E$, minimization of Faraday residue, and an adjusted version of the maximum directional derivative of the magnetic field (MDD-$B$) technique all produce {reasonably} similar coordinate axes. We use virtual MMS data from a particle-in-cell simulation of this event to estimate the errors in the coordinate axes and reconnection rate associated with MVA-$v_e$ and MDD-$B$. The $L$ and $M$ directions are most reliably determined by MVA-$v_e$ when the spacecraft observes a clear electron jet reversal. When the magnetic field data has errors as small as 0.5\% of the background field strength, the $M$ direction obtained by MDD-$B$ technique may be off by as much as 35$^\circ$. The normal direction is most accurately obtained by MDD-$B$. Overall, we find that these techniques were able to identify $E_M$ from the virtual data within error bars $\geq$20\%.

Nitric Oxide in Climatological Global Energy Budget During 1982-2013

Publisher: name: arXiv
Year: 2018
Subjects: subject: Space Physics (physics.space-ph)
subject: FOS: Physical sciences

description: Over the past decades, temperature and density of the upper atmosphere show negative trends and decrease of the upper atmospheric temperature is attributed to the declining neutral density. Specifically, nitric oxide (NO) and carbon dioxide (CO2) govern thermospheric cooling at 5.3 and 15 micron, respectively. While a lot of efforts have focused on the CO2 effects on the long-term trends, relatively less attention has been paid to the impacts by NO, which responds to solar and geomagnetic activities dynamically. In this study, we investigate the role of NO in climatological global energy budget for the recent three solar cycles using the Global Ionosphere Thermosphere Model. From 1982 to 2013, the F10.7 and Ap indices showed a decadal decrease of ~8% and ~20%, respectively. By imposing temporal-varying F10.7 and Ap values in the simulations, we find a decadal change of -0.28x1011 W or -17.3% in total NO cooling power, which agrees well with that (-0.34x1011 W or -17.2%) from the empirical Thermosphere Climate Index derived from the TIMED/SABER data. Neutral density decreases by 10-20% at 200-450km and Tex decreases by 25.3 K per decade. The deduced-decadal change of NO cooling reaches ~25% of the sum of total heating at ~130 km and its significance decreases with altitude.

description: We show how identification of absolutely flat directions allows the construction of a new class of compactified string theories with reduced gauge symmetry that may or may not be continuously connected to the original theory. We use this technique to construct a class of 3 generation models with just the Standard Model gauge group after compactification. We discuss the low-energy symmetries necessary for a phenomenologically viable low-energy model and construct an example in which these symmetries are identified with string symmetries which remain unbroken down to the supersymmetry breaking scale. Remarkably the same symmetry responsible for stabilising the nucleon is also responsible for ensuring one and only one pair of Higgs doublets is kept light. We show how the string symmetries also lead to textures in the quark and lepton mass matrices which can explain the hierarchy of fermion masses and mixing angles.

description: The mechanism of a confining medium is investigated within the Nambu-Jona-Lasinio (NJL) approach. It is shown that a confining medium can be realized in the bosonized phase of the NJL model due to vacuum fluctuations of both fermion and Higgs (scalar fermion-antifermion collective excitation) fields. In such an approach there is no need to introduce Dirac strings.

description: We present an analysis of the MSW neutrino oscillation solutions of the solar neutrino problem in the framework of two-neutrino mixing in the enlarged parameter space $(Δm^2, \tan^2θ)$ with $θ\in (0,\fracπ{2})$. Recently, it was pointed out that the allowed region of parameters from a fit to the measured total rates can extend to values $θ\geq \fracπ{4}$ (the so called ``dark side'') when higher confidence levels are allowed. The purpose of this letter is to reanalize the problem including all the solar neutrino data available, to discuss the dependence on the statistical criteria in the determination of the CL of the ``dark side'' and to extract the corresponding limits on the largest mixing allowed by the data. Our results show that when the Super-Kamiokande data on the zenith angle distribution of events and the spectrum information is included, the regions extend more into the dark side.

Vector mesons $ρ, ρ'$ and $ρ''$ diffractively photo- and leptoproduced
Creators: name: Kulzinger, G.
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In the framework of non-perturbative QCD we calculate high-energy diffractive production of vector mesons $\rh, \rh'$ and $\rh''$ by real and virtual photons on a nucleon. The initial photon dissociates into a $q\bar{q}$-dipole and transforms into a vector meson by scattering off the nucleon which, for simplicity, is represented as quark-diquark. The relevant dipole-dipole scattering amplitude is provided by the non-perturbative model of the stochastic QCD vacuum. The wave functions result from considerations in the frame of light-front dynamics; the physical $\rh'$- and $\rh''$-mesons are assumed to be mixed states of an active 2S-excitation and some residual rest (2D- and/or hybrid state). We obtain good agreement with the experimental data and get an understanding of the markedly different $π^+π^-$-mass spectra for photoproduction and $e^+e^-$-annihilation.

description: Exact diagonalisations of the extended Hubbard model are performed. In the insulating regime it is shown that the nearest neighbour copper-oxygen repulsion, $V$, leads to Frenkel excitons in the charge transfer gap at values of $V$ of the order of copper-oxygen hybridisation, $t$. In the metallic regime it is shown that the static charge-transfer and density-density correlation functions diverge as a function of $V$, indicating a charge-tansfer instability and phase separation. This is accompanied by a softening of the $q \to 0$ mode of the dynamic correlation functions which is associated with the excitonic excitations responsible for the superconducting correlations observed in the proximity of the phase separation boundary of ref. \cite{cv95b}.

 Holotype: — TANZANIA: Uluguru-Berge. Lukwangule-Plateau auf Bäumen, zwischen Flechten. 29 November 1898, W.Goetze 283 (B 20 0015728!).
 Note: — Pichi Sermolli (1985) cites a specimen from Rwanda (Northern Province: Volcano NP, selle entre le Karisimbi et le Visoke, Ruhengeri (= Musanze), forêt-prairie à vieux Hagenia, épiphyte sur Hagenia 3000 m, 20 January 1972, P.Bamps 2963 [BR0000013601546!]) that he assigns to Asplenium goetzei: „The frond shows a considerable polymorphism both in the outline of the blade and in the shape of the pinnae, mainly in connection with the different value of the ratio between their length and breadth. This variability frequently occurs also in fronds from the same rhizome. However, the long-creeping rhizome, the structure of the paleae, the shape of the ultimate segments, long connected together and with a peculiar fissure in the line of connection, the apex of segments and the position of sori well characterize the species“ (Pichi Sermolli 1985: 136). There is a similar specimen from Eastern D.R. Congo (Kahuzi-Biéga, Van der Veken 8864 (BR 0000013601508) also representing A. uhligii.
 The available keys are often insufficient to clearly separate Asplenium goetzei from A. uhligii. In the protologue from A. goetzii an important character „kriechende Rhizome, welche am Grunde von dunkelrostbraunen, nicht schwarzbraunen Schuppen bedeckt sind“ is cited by Hieronymus (1900: 344) („creeping rhizomes that are covered with dark rust-brown, and not blackish-brown scales“). We studied the scales of the type specimen (Fig. 25 D–F) which have reddish-brown thickened cell walls and can be easily distinguished from those of A. uhligii (Fig. 25 A–C). Thus, we agree with Beentje (2008) that typical A. goetzei is restricted to the Uluguru Mountains of Tanzania, and that the two cited specimens from Pichi Sermolli (1985) represent a form of A. uhligii. Therefore, A. goetzei does not occur in Rwanda.

description: Within the context of massive N-component $ϕ^4$ scalar field theory, we use asymptotic Pade-approximant methods to estimate from prior orders of perturbation theory the five-loop contributions to the coupling-constant beta-function $β_g$, the anomalous mass dimension $γ_m$, the vacuum-energy beta-function $β_v$, and the anomalous dimension $γ_2$ of the scalar field propagator. These estimates are then compared with explicit calculations of the five-loop contributions to $β_g$, $γ_m$, $β_v$, and are seen to be respectively within 5%, 18%, and 27% of their true values for $N$ between 1 and 5. We then extend asymptotic Pade-approximant methods to predict the presently unknown six-loop contributions to $β_g$, $γ_m$, and $β_v$. These predictions, as well as the six-loop prediction for $γ_2$, provide a test of asymptotic Pade-approximant methods against future calculations.

Particle creation and energy conditions for a quantized scalar field in the presence of an external, time-dependent, Mamev-Trunov potential
Creators: name: Pfenning, Michael J.
Publisher: name: arXiv
Year: 2018
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We study the behavior of a massless, quantized, scalar field on a two-dimensional cylinder spacetime as it responds to the time-dependent evolution of a Mamev-Trunov potential of the form $V(x,t) = 2 ξδ(x) θ(-t)$. We begin by constructing mode solutions to the classical Klein-Gordon-Fock equation with potential on the whole spacetime. For a given eigen-mode solution of the IN region of the spacetime ($t<0$), we determine its evolution into the OUT region ($t>0$) through the use of a Fourier decomposition in terms of the OUT region eigen-modes. The classical system is then second quantized in the canonical quantization scheme. On the OUT region, there is a unitarily equivalent representation of the quantized field in terms of the OUT region eigen-modes, including zero-frequency modes which we also quantize in a manner which allows for their interpretation as particles in the typical sense. After determining the Bogolubov coefficients between the two representations, we study the production of quanta out of the vacuum when the potential turns off. We find that the number of "particles" created on the OUT region is finite for the standard modes, and with the usual ambiguity in the number of particles created in the zero frequency modes. We then look at the renormalized expectation value of the stress-energy-tensor on the IN and OUT regions for the IN vacuum state. We find that the resulting stress-tensor can violate the null, weak, strong, and dominant energy conditions because the standard Casimir energy-density of the cylinder spacetime is negative. Finally, we show that the same stress-tensor satisfies a quantum inequality on the OUT region.

Publisher: name: University of Nevada, Las Vegas
publisherIdentifier: https://ror.org/0406gha72
publisherIdentifierScheme: ROR
Year: 2022

description: This Thesis reports the design, simulation, and layout of a switching power supply controller chip for a fly-back switching power supply.  The controller chip was designed using ON’s Semiconductor C5 process. The resulting switching power supply using the controller chip consists of using various off-chip components such as a power MOSFET, transformer, and capacitors. The main components used in the integrated circuit include a bandgap reference voltage circuit which outputs a reference voltage of 1.25V, a ring oscillator having a nominal frequency of 5MHz, a high-gain comparator, and a buffer that can drive a 5pF capacitor.  Under normal simulation conditions the reference voltage was 1.25V, power supply voltage was 5V, a normal operating temperature of 27°C, and a load current of 2.5A which resulted in an output voltage of 12.5V with a 350mV ripple voltage caused by the control loop’s hysteresis. The higher value of ripple in the output voltage was shown to be reduced with a larger, thus more expensive, filter capacitor. The output in this nominal case resulted in an average power consumption of the switching power supply of around 16mW while supplying more than 30W to the load. The Thesis reports additional simulation results including temperature being changed between 0°C to 100°C, the power supply voltage being changed away from the standard 5V, and the load current varying between 10mA and 6.25A. During all tests the integrated circuit performed well and under worst-case conditions an efficiency of above 89%.

description: Asplenium kassneri Hieronymus (1911: 376).
 Holotype: —D.R. CONGO. Nord Kivu: Ruwenzori, October 1908, T.W.Kassner 3114 (B, not found).
 Note: —The specimen Kassner 3114 at K (K000423913 [digital image!]) is Asplenium volkensii and has as such been correctly identified by Pichi Sermolli on a determinavit slip. Pichi Sermolli (1985: 124) did not see the holotype of A. kassneri, but saw a photo and a fragment, and maintained the taxon on the base of two specimens from Rwanda and D.R. Congo (Auquier 4520 BR0000024680196 and Auquier 2289 BR0000024680189), but they belong to A. uhligii (see above under A. uhligii).
 Unfortunately, the holotype of A. kassneri at B was lent to BM, and is now missing. According to Pichi Sermolli the collection Kassner 3114 was distributed before the description of A. kassneri and consists of two species.
 Beentje (2008) reduced A. kassneri to synonymy of A. uhligii. He argued that the protologue already indicated that the two taxa were close, and with the amount of material available now, there were no remaining consistent differences between what is described in the protologue of A. kassneri and A. uhligii. This decision was also accepted by Roux (2009). However, there is a a character of the rhizome scales, that indicates that A. kassneri and A. uhligii may represent different taxa. In the protologue of A. kassneri, Hieronymus (1911) wrote “Die Spreuschuppen der Rhizome sind jedoch, obgleich äusserlich ähnlich von verschiedenem Bau und unterscheiden sich besonders dadurch, dass die Zellen mehrerer Reihen des Randes bei A. Kassneri kleiner sind als die in der Mitte der Schuppen befindlichen und entsprechend dünnere Innenwände zeigen, während bei A. uhligii die Zellen in dieser Beziehung ziemlich gleichartig sind und im allgemeinen auch viel dickere und dunklere Innenwände besitzen, so dass die Spreuschuppen dunkler gefärbt erscheinen und weniger durchsichtig sind.” (Hieronymus 1911: 377–378) (“The rhizome scales, however, despite superficially similar, show a different structure and are distinct especially in several rows of the scale margin of A. kassneri, that are smaller than the cells in the scale center and show thinner walls, while in A. uhligii the cells are almost equal in this respect and the cell walls are much thicker and darker, so that the scales appear darker and less transparent”). We have not yet seen plants with this kind of scales, but they must be searched for.

Hard exclusive electroproduction of two pions and their resonances

description: We study the hard exclusive production of two pions in the virtual photon fragmentation region with various invariant masses including the resonance region. The amplitude is expressed in terms of two-pion light cone distribution amplitudes ($2π$DA's). We derive dispersion relations for these amplitudes, which enables us to fix them completely in terms of $ππ$ scattering phases and a few low-energy subtraction constants determind by the effective chiral lagrangian. Quantitative estimates of the resonance as well $ππ$ background DA's at low normalization point are made. We also prove certain new soft pion theorem relating two-pion DA's to the one-pion DA's. Crossing relations between $2π$DA's and parton distributions in a pion are discussed. We demontrate that by studying the \underline{shape} of the $ππ$ mass spectra (not absolute cross section!) in a diffractive electroproduction one can extract the deviation of the meson ($π,ρ,$ etc.) wave functions from their asymptotic form $6 z(1-z)$ and hence to get important information about the structure of mesons. We suggest (alternative to Söding's) parametrization of $ππ$ spectra which is suitable for large photon virtuality.

description: The interconversion between left- and right-handed helical folds of a polypeptide defines a dual-funneled free energy landscape. In this context, the funnel minima are connected through a continuum of unfolded conformations, evocative of the classical helix-coil transition. Physical intuition and recent conjectures suggest that this landscape can be mapped by assigning a left- or right-handed helical state to each residue. We explore this possibility using all-atom replica exchange molecular dynamics and an Ising-like model, demonstrating that the energy landscape architecture is at odds with a two-state picture. A three-state model - left, right, and unstructured - can account for most key intermediates during chiral interconversion. Competing folds and excited conformational states still impose limitations on the scope of this approach. However, the improvement is stark: Moving from a two-state to a three-state model decreases the fit error from 1.6 $k_B T$ to 0.3 $k_B T$ along the left-to-right interconversion pathway.

description: We challenge the conventional view of how post-socialist economies function by incorporating the unofficial economy into the analysis of the overall economy. The interpretation of the dynamics of transition is then seen to differ. A simple framework for understanding the evolution of the unofficial economy--and the linkages between both economies—is advanced. It highlights the main characteristics of "unofficialdom," contrasting conventional notions of "informal" or "shadow" economies, and also focusses on the determinants of the decision to cross-over from one segment of the economy to the other. The empirical evidence, based both on micro-surveys as well as on a top-down ("macro-electric") comparative country methodology, suggests the potential usefulness of the overall framework. Integrating the unofficial economy into the study of the overall economy matters analytically and empirically. For instance, the interpretation of national income, of sectoral trends (such as trade, services, and exports), and of labor markets and household patterns take on an additional dimension, often leading to results that differ from analysis in which the unofficial economy is ignored. By the mid-nineties the Former Soviet counties are estimated to have over one-third of their activity in the unofficial economy, while in Central and Eastern Europe the average is close to one-quarter. Intra-regional variance is large, with some countries having 10-15% of their economy engaged in unofficial activity while others exceed 50%. The growth of unofficial activities in most post-socialist countries, and its mitigating effect on the decline in official output during the early stages of transition, have been marked. Although the preliminary nature of this investigation ought to be underscored, the cross-country empirical results appear to be broadly consistent with the hypothesized determinants of the unofficial economy dynamics. In particular, fast market liberalization, macro-stability and institution of a stable and moderate tax regime is emphasized. While widespread, most of "unofficialdom" in the region is found to be relatively shallow, i.e., subject to reversal by appropriate economic policies. The simple framework and evidence presented have implications for measurement and forecasting, and for policy-making. The lessons for policy (such as in social protection and taxation) are found to differ from conventional advice given. In other areas, such as liberalization and privatization, even faster reforms than often advocated are called for.

description: We derive a full set, and determine the twist, of helicity amplitudes for diffractive production of light to heavy vector mesons in deep inelastic scattering. For large $Q^{2}$ all helicity amplitudes but the double-flip are calculable in perturbative QCD and are proportional to the gluon structure function of the proton at a similar hard scale. We find a substantial breaking of the $s$-channel helicity conservation which must persist also in real photoproduction.

description: Occupant behavior and building characteristics play decisive roles in household dampness. Few studies have investigated the influence of intermittent behavior habits on home dampness in different seasons. In this article, we investigated the status of dampness indicators during the Hot Summer and Cold Winter Zone based on the data collected from 1146 residences through a cross-sectional survey. Herein, we explored the association of occupant behavior and building characteristics with three dampness indicators, including visible mold spots, damp stains, and condensation. The results show that household dampness is common, with 43.4%, 37.8%, and 24.4% of households reporting condensation, damp stains, and visible mold spots, respectively. Mold-proofing is highly required for walls, ground corners, and ceiling corners. In the multiple logistic regression analyses, nonrural areas, younger dwelling age, sufficient sunlight, and higher floors are protective factors against household dampness. Floors located between the 10th and 18th levels may be better for moisture- and mold-proofing. In spring, longer window-opening duration is a protective factor against dampness-related issues. Space heating devices and air conditioners are associated with reduced odds of mold, as well as the increase of use duration for air conditioners.

Destructive Interference of Dualities

Year: 1997

description: The soldering mechanism has been shown to represent the quantum interference effect between self and anti-self dual aspects of a given symmetry. This mechanism was used to show that the massive mode of the 2D Schwinger model results from the constructive interference between the right and the left massless modes of chiral Schwinger models. Similarly, the topologically massive modes resulting from the bosonization of 3D massive Thirring models of opposite mass signatures, are fused into the two massive modes of the 3D Proca model, thanks to the interference of dualities characteristic of the soldering mechanism. In this work, we show that the field theoretical analog of destructive quantum mechanical interference may also be represented by the soldering mechanism. This phenomenon is illustrated by the fusion of two (diffeomorphism) invariant self-dual scalars described by right and left chiral-WZW actions, producing a Hull non-mover field. After fusion, right and left moving modes disappear from the spectrum, displaying the claimed (destructive) interference of dualities.

description: The escape probability $ξ_{x}$ from a site $x$ of a one-dimensional disordered lattice with trapping is treated as a discrete dynamical evolution by random iterations over nonlinear maps parametrized by the right and left jump probabilities. The invariant measure of the dynamics is found to be a multifractal. However the measure becomes uniform over the support when the disorder becomes weak for any non-zero trapping probability. Implications of our findings in terms of diffusion are discussed.
