description: We model the progressive maturation of a heterogeneous mass towards a gravity-driven instability, characterized by the competition between frictional sliding and tension cracking, using array of slider blocks on an inclined basal surface, which interact via elastic-brittle springs. A realistic state- and rate-dependent friction law describes the block-surface interaction. The inner material damage occurs via stress corrosion. Three regimes, controlling the mass instability and its precursory behavior, are classified as a function of the ratio $T_c/T_f$ of two characteristic time scales associated with internal damage/creep and with frictional sliding. For $T_c/T_f \gg 1$, the whole mass undergoes a series of internal stick and slip events, associated with an initial slow average downward motion of the whole mass, and progressively accelerates until a global coherent runaway is observed. For $T_c/T_f \ll 1$, creep/damage occurs sufficiently fast compared with nucleation of sliding, causing bonds to break, and the bottom part of the mass undergoes a fragmentation process with the creation of a heterogeneous population of sliding blocks. For the intermediate regime $T_c/T_f \sim 1$, a macroscopic crack nucleates and propagates along the location of the largest curvature associated with the change of slope from the stable frictional state in the upper part to the unstable frictional sliding state in the lower part. The other important parameter is the Young modulus $Y$ which controls the correlation length of displacements in the system.

description: The leading term for the energy of a bound state of k-quarks and k-antiquarks is proportional to its separation L. These k-string configurations have a Luscher term associated with their quantum fluctuations which is typically a 1/L correction to the energy. We review the status of tensions and Luscher terms in the context of lattice gauge theory, Hamiltonian methods, and gauge/gravity correspondence. Furthermore we explore how different representations of the k-string manifest themselves in the gauge/gravity duality. We calculate the Luscher term for a strongly coupled SU(N) gauge theory in (2+1) dimensions using the gauge/gravity correspondence. Namely, we compute one-loop corrections to a probe D4-brane embedded in the Cvetic, Gibbons, Lu, and Pope supergravity background. We investigate quantum fluctuations of both the bosonic and the fermionic sectors.

Spin motive forces and current fluctuations due to Brownian motion of domain walls

description: We compute the power spectrum of the noise in the current due to spin motive forces by a fluctuating domain wall. We find that the power spectrum of the noise in the current is colored, and depends on the Gilbert damping, the spin transfer torque parameter $β$, and the domain-wall pinning potential and magnetic anisotropy. We also determine the average current induced by the thermally-assisted motion of a domain wall that is driven by an external magnetic field. Our results suggest that measuring the power spectrum of the noise in the current in the presence of a domain wall may provide a new method for characterizing the current-to-domain-wall coupling in the system.

description: In this study, we aimed to study the effect of fluid shear stress on fibroblasts and BMSCs on plane and groove topographies. The results showed that 0.6-Hz stress had the greatest influence on the alignment, polarity, migration and adhesion of fibroblasts on plane by increasing the expression of reoriented actin and vinculin; whereas 1.0-Hz stress promoted differentiation of fibroblasts into myofibroblasts by increasing Col-I and α-SMA expression. Interestingly, under the given frequency stress, the groove structure strengthened the above characteristics of fibroblasts beyond adhesion, and promoted differentiation of BMSCs into myofibroblasts. The above results indicate that 0.6 Hz may improve the implant-tissue sealing, while 1.0-Hz stress probably causes the disordered fiber deposition around implants.

Understanding Antibiotic Resistance: Quantifying the Presence of the sul1 Gene in Escherichia coli and Analysing its Effect on the Bacterial Growth Rate Under Different Concentrations of Sulfamethoxazole.

subject: Escherichia coli

description: This paper focuses on understanding the mechanisms of antibiotic resistance in Escherichia coli, focusing on the presence of the antibiotic resistance gene sul1 and its effect on the bacterial growth rate, as the increasing antibiotic resistance, mentioned in various media, is a cause for concern. The research question: “Are the number of sul1 genes in the plasmids of Escherichia coli dependent on the exposure to antibiotic concentration of sulfamethoxazole and do the numbers of sul1 genes/cell affect the growth rate?”, is answered through an empirical study, analysis and interpretation of obtained data, and literature research. The study shows that no general conclusion can be drawn from the results, as the individual strains behave differently. Although, an increase in sul1 genes with increasing antibiotic concentration can be observed, it does not hold true for all strains. This can also be said for the effect of the number of sul1 copies on the bacterial growth rate. These results show how challenging it is to counteract and understand the increasing antibiotic resistance as no clear pattern can be seen which could be applied to a numerous bacteria. Hence, it is of utmost importance to continue research in hopes of finding correlations that could give an insight on how to curb the spread of antibiotic resistance.
Performance Analysis of 60nm gate length III-V InGaAs HEMTs: Simulations vs. experiments

description: An analysis of recent experimental data for high-performance In0.7Ga0.3As high electron mobility transistors (HEMTs) is presented. Using a fully quantum mechanical, ballistic model, we simulate In0.7Ga0.3As HEMTs with gate lengths of LG = 60nm, 85, and 135 nm and compare the result to the measured I-V characteristics including draininduced barrier lowering, sub-threshold swing, and threshold voltage variation with gate insulator thickness, as well as on-current performance. To first order, devices with three different oxide thicknesses and channel lengths can all be described by our ballistic model with appropriate values of parasitic series resistance. For high gate voltages, however, the ballistic simulations consistently overestimate the measured on-current, and they do not show the experimentally observed decrease in on-current with increasing gate length. With no parasitic series resistance at all, the simulated on-current of the LG = 60 nm device is about twice the measured current. According to the simulation, the estimated ballistic carrier injection velocity for this device is about 2.7 x 10^7 cm/s. Because of the importance of the semiconductor capacitance, the simulated gate capacitance is about 2.5 times less than the insulator capacitance. Possible causes of the transconductance degradation observed under high gate voltages in these devices are also explored. In addition to a possible gate-voltage dependent scattering mechanism, the limited ability of the source to supply carriers to the channel, and the effect of nonparabolicity are likely to play a role. The drop in on-current with increasing gate length is an indication that the devices operate below the ballistic limit.

Eroding market stability by proliferation of financial instruments

description: We contrast Arbitrage Pricing Theory (APT), the theoretical basis for the development of financial instruments, with a dynamical picture of an interacting market, in a simple setting. The proliferation of financial instruments apparently provides more means for risk diversification, making the market more efficient and complete. In the simple market of interacting traders discussed here, the proliferation of financial instruments erodes systemic stability and it drives the market to a critical state characterized by large susceptibility, strong fluctuations and enhanced correlations among risks. This suggests that the hypothesis of APT may not be compatible with a stable market dynamics. In this perspective, market stability acquires the properties of a common good, which suggests that appropriate measures should be introduced in derivative markets, to preserve stability.

description: We discuss spectropolarimetric measurements of photospheric (Fe I 630.25 nm) and chromospheric (Ca II 854.21 nm) spectral lines. Our long-term goal is to diagnose properties of the magnetic field near the base of the corona. We compare ground-based two-dimensional spectropolarimetric measurements with (almost) simultaneous space-based slit spectropolarimetry. The ground-based observations were obtained May 20, 2008, with IBIS in spectropolarimetric mode, The space observations were obtained with the Spectro-Polarimeter aboard the HINODE satellite. The agreement between the near-simultaneous co-spatial IBIS and HINODE Stokes-V profiles at 630.25 nm is excellent, with V/I amplitudes compatible with to within 1 %. IBIS QU measurements are affected by residual crosstalk from V, arising from calibration inaccuracies, not from any inherent limitation of imaging spectroscopy. We use a PCA analysis to quantify the detected cross talk. Chromospheric magnetic fields are difficult to constrain by polarization of Ca II lines alone. However, we demonstrate that high cadence, high angular resolution monochromatic images of fibrils in Ca II and H-alpha, can be used to improve the magnetic field constraints, under conditions of high electrical conductivity. Such work is possible only with time series datasets from two-dimensional spectroscopic instruments under conditions of good seeing.

description: We calculate the radio-frequency spectrum of a trapped cloud of cold bosonic atoms in an optical lattice. Using random phase and local density approximations we produce both trap averaged and spatially resolved spectra, identifying simple features in the spectra that reveal information about both superfluidity and correlations. Our approach is exact in the deep Mott limit and in the deep superfluid when the hopping rates for the two internal spin states are equal. It contains final state interactions, obeys the Ward identities (and the associated conservation laws), and satisfies the $f$-sum rule. Motivated by earlier work by Sun, Lannert, and Vishveshwara [Phys. Rev. A \textbf{79}, 043422 (2009)], we also discuss the features which arise in a spin-dependent optical lattice.

description: Spectroscopic and eclipsing binary systems offer the best means for determining accurate physical properties of stars, including their masses and radii. The data available for low-mass stars have yielded firm evidence that stellar structure models predict smaller radii and higher effective temperatures than observed, but the number of systems with detailed analyses is still small. In this paper we present a complete reanalysis of one of such eclipsing systems, CM Dra, composed of two dM4.5 stars. New and existing light curves as well as a radial velocity curve are modeled to measure the physical properties of both components. The masses and radii determined for the components of CM Dra are M1=0.2310+/-0.0009 Msun, M2=0.2141+/-0.0010 Msun, R1=0.2534+/-0.0019 Rsun, and R2=0.2396+/-0.0015 Rsun. With relative uncertainties well below the 1% level, these values constitute the most accurate properties to date for fully convective stars. This makes CM Dra a valuable benchmark for testing theoretical models. In comparing our measurements with theory, we confirm the discrepancies reported previously for other low-mass eclipsing binaries. These discrepancies seem likely to be due to the effects of magnetic activity. We find that the orbit of this system is slightly eccentric, and we have made use of eclipse timings spanning three decades to infer the apsidal motion and other related properties.

The result shows that the well known expression with the directional temperature can be derived based on the inverse temperature four vector. The directional temperature in the past literature was the result of mathematical manipulation and its physical meaning is not clear. The inverse temperature four vector has, in contrast, clear meaning to understand relativistic thermodynamical processes.

description: As anticipated in [1], elaborated in [2-4], and explicitly formulated in [5], the Dotsenko-Fateev integral discriminant coincides with conformal blocks, thus providing an elegant approach to the AGT conjecture, without any reference to an auxiliary subject of Nekrasov functions. Internal dimensions of conformal blocks in this identification are associated with the choice of contours: parameters of the DV phase of the corresponding matrix models. In this paper we provide further evidence in support of this identity for the 6-parametric family of the 4-point spherical conformal blocks, up to level 3 and for arbitrary values of external dimensions and central charges. We also extend this result to multi-point spherical functions and comment on a similar description of the 1-point function on a torus.

description: The availability of Bose-Einstein condensates as mesoscopic or macroscopic quantum objects has aroused new interest in the possiblity of making and detecting coherent superpositions involving many atoms. In this article we show that it may be possible to generate such a superposition state in a reasonably short time using Feshbach resonances to tune the inter-atomic interactions in a double-well condensate. We also consider the important problem of distinguishing whether a coherent superposition or a statistical mixture is generated by a given experimental procedure. We find that unambiguously distinguishing even a perfect `NOON' state from a statistical mixture using standard detection methods will present experimental difficulties.

description: Biochemical reaction networks in living cells usually involve reversible covalent modification of signaling molecules, such as protein phosphorylation. Under conditions of small molecule numbers, as is frequently the case in living cells, mass action theory fails to describe the dynamics of such systems. Instead, the biochemical reactions must be treated as stochastic processes that intrinsically generate concentration fluctuations of the chemicals. We investigate the stochastic reaction kinetics of covalent modification cycles (CMCs) by analytical modeling and numerically exact Monte-Carlo simulation of the temporally fluctuating concentration. Depending on the parameter regime, we find for the probability density of the concentration qualitatively distinct classes of distribution functions, including power law distributions with a fractional and tunable exponent. These findings challenge the traditional view of biochemical control networks as deterministic computational systems and suggest that CMCs in cells can function as versatile and tunable noise generators.

The effects of exercise on the sleep of unfit individuals
Creators: name: Griffin, SJ
Publisher: name: University Of Tasmania
Year: 2023

description: A facilitative effect of daytime exercise on SWS has been cited as evidence in support of the bodily restorative theory of sleep. However, this effect has not been observed in studies using unfit individuals. It was hypothesized that the failure of earlier studies to find a facilitative effect of exercise on SWS in unfit subjects was due to a stress induced by the exercise sessions which disrupted sleep and counteracted the facilitative effect. Steps were taken to minimize stress by using afternoon exercise, a range of exercise levels and a number of exercise sessions for each subject. Thus the experiment consisted of a 4 x 4 factorial design with repeated measures on one factor (N = 24). The first variable consisted of 4 exercise levels (no exercise, 510% VO2max for 45 mins., 75% VO2max for 60 mins., and maximum output for 60 mins.) while the second variable represented 4 measurement occasions (baseline and three nights following 1, 3 and 5 consecutive exercise days). It was hypothesized that a facilitative effect of exercise would be observed under conditions in which the stress factor was minimized. No effect of exercise on SWS was found in any condition, nor was there any evidence that a hypothetical stress factor accounted for the results. These findings are inconsistent with present statements of the bodily restorative theory of SWS. It is possible, however, that SWS levels may be responsive to long term rather than short term alterations in activity levels.

Septic tanks and adsorption fields in Tasmania : matching environmental conditions with operating requirements
Creators: name: Grauer, RB
Publisher: name: University Of Tasmania

description: Septic tanks and soil adsorption fields are a commonly used wastewater treatment system in unsewered areas. The biological processes on which they rely were considered in detail and their operating requirements established along with the assumptions underlying the design of the treatment system. The principal regions in which septic tanks and adsorption fields are used in Tasmania were also established and the environmental conditions in these areas were compared with the operating and design conditions of septic tank and adsorption field systems. From this the suitability of septic tank wastewater treatment in the particular areas of use was predicted. In highland areas septic tank and adsorption field systems were considered to be unsuitable for wastewater treatment whilst in lowland areas their suitability is dependent upon site characteristics. No region of septic tank and adsorption field use in Tasmania was considered to be completely suitable for this form of wastewater treatment. The environmental conditions of two dissimilar sites, Mt. Mawson and Carlton, were characterised and the performance of septic tank and adsorption field systems under them assessed. The behaviour of the treatment systems was consistent with the predictions made earlier. Within this study several deficiencies in septic tank and adsorption field design and operation, both in Tasmania generally and specifically at the two study sites, were highlighted. Remedial action was suggested where appropriate.

description: We have measured a strong increase of the low-temperature resistivity $ρ_{xx}$ and a zero-value plateau in the Hall conductivity $σ_{xy}$ at the charge neutrality point in graphene subjected to high magnetic fields up to 30 T. We explain our results by a simple model involving a field dependent splitting of the lowest Landau level of the order of a few Kelvin, as extracted from activated transport measurements. The model reproduces both the increase in $ρ_{xx}$ and the anomalous $ν=0$ plateau in $σ_{xy}$ in terms of coexisting electrons and holes in the same spin-split zero-energy Landau level.

description: La protección de los consumidores en Colombia encuentra sustento en una serie de normas que conforman el ordenamiento jurídico, algunas pertenecientes a la esfera del derecho privado y otras que hacen parte del derecho público. Todas ellas están contenidas en los diferentes regímenes que regulan una determinada actividad económica. Dentro de los aspectos que se han reglamentado están el acceso a una información cierta, suficiente y la prohibición de la publicidad engañosa. Estos derechos buscan ser protegidos a través de reglamentaciones desde la perspectiva del mercado y otras desde la salvaguarda de la salud pública las cuales en conjunto con las competencias de las entidades que las aplican (SIC e INVIMA) pueden entrar en conflicto en la aplicación de un sistema normativo determinado. Con el fin de establecer los respectivos límites normativos y funcionales, se describirán las funciones del Invima y SIC, luego se afrontarán las normas sustanciales en lo que tiene ver con la vigilancia en la información y la publicidad desde las distintas ópticas, también se abordaran casos en la cuales pueden existir una colisión de competencias, para luego determinar metodológicamente los criterios que se deben atender con el propósito de aplicar un régimen determinado.
description: Consumer protection in Colombia is supported by a series of regulations that make up the legal system, some belonging to the sphere of private law and others that are part of public law. All of them are contained in the different regimes that regulate a certain economic activity. Among the aspects that have been regulated are access to accurate and sufficient information and the prohibition of misleading advertising. These rights seek to be protected through regulations from the perspective of the market and others from the safeguarding of public health which, together with the powers of the entities that apply them (SIC and INVIMA) may conflict in the application of a determined regulatory system. In order to establish the respective regulatory and functional limits, the functions of INVIMA and SIC will be described, then the substantial regulations regarding surveillance of information and advertising will be addressed from different perspectives, cases will also be addressed. in which there may be a collision of competencies, to then methodologically determine the criteria that must be met in order to apply a certain regime.
Single- and multi-peak solitons in two-component models of metamaterials and photonic crystals

description: We report results of the study of solitons in a system of two nonlinear-Schrodinger (NLS) equations coupled by the XPM interaction, which models the co-propagation of two waves in metamaterials(MMs). The same model applies to photonic crystals (PCs), as well as to ordinary optical fibers, close to the zero-dispersion point. A peculiarity of the system is a small positive or negative value of the relative group-velocity dispersion (GVD) coefficient in one equation, assuming that the dispersion is anomalous in the other. In contrast to earlier studied systems of nonlinearly coupled NLS equations with equal GVD coefficients, which generate only simple single-peak solitons, the present model gives rise to families of solitons with complex shapes, which feature extended oscillatory tails and/or a double-peak structure at the center. Regions of existence are identified for single- and double-peak bimodal solitons, demonstrating a broad bistability in the system. Behind the existence border, they degenerate into single-component solutions. Direct simulations demonstrate stability of the solitons in the entire existence regions. Effects of the group-velocity mismatch (GVM) and optical loss are considered too. It is demonstrated that the solitons can be stabilized against the GVM by means of the respective "management" scheme. Under the action of the loss, complex shapes of the solitons degenerate into simple ones, but periodic compensation of the loss supports the complexity.

description: The changes in the electronic structure of V2O3 across the metal-insulator transition induced by temperature, doping and pressure are identified using high resolution x-ray absorption spectroscopy at the V pre K-edge. Contrary to what has been taken for granted so far, the metallic phase reached under pressure is shown to differ from the one obtained by changing doping or temperature. Using a novel computational scheme, we relate this effect to the role and occupancy of the a1g orbitals. This finding unveils the inequivalence of different routes across the Mott transition in V2O3

description: Near-infrared spectroscopic data for the five Seyfert galaxies with jet-gas interaction Mrk 348, Mrk 573, Mrk 1066, NGC 7212, and NGC 7465, taken with the LIRIS near-infrared camera/spectrometer at the William Herschel Telescope (WHT) are reported. The long-slit spectra reveal the characteristic strong emission lines of this type of objects. Many forbidden transitions and hydrogen recombination lines are employed here to study the excitation and ionization mechanisms that are dominating the narrow-line region emission of these objects, that is affected by the radio-jet interaction. Several absorption features are also detected in the H and K bands of these galaxies, allowing us to identify the spectral types that are producing them. We find that the continuum can be reproduced by a combination of late-type stellar templates plus a Blackbody component associated to host dust, mainly contributing to the K band emission. The detection of the permitted O I and Fe II lines and broad components of the hydrogen recombination lines in the spectra of Mrk 573 and NGC 7465 allows the reclassification of these two galaxies that are not canonical Type-2 Seyferts: Mrk 573 is confirmed to be an obscured Narrow-line Seyfert 1 and NGC 7465 is revealed for the first time as a Type-1 LINER through its near-infrared spectrum.

description: We study theoretically the interactions of excitonic states with surface electromagnetic modes of small-diameter (~1 nm) semiconducting single-walled carbon nanotubes. We show that these interactions can result in strong exciton-surface-plasmon coupling. The exciton absorption line shape exhibits Rabi splitting ~0.1 eV as the exciton energy is tuned to the nearest interband surface plasmon resonance of the nanotube. We also show that the quantum confined Stark effect may be used as a tool to control the exciton binding energy and the nanotube band gap in carbon nanotubes in order, e.g., to bring the exciton total energy in resonance with the nearest interband plasmon mode. The exciton-plasmon Rabi splitting we predict here for an individual carbon nanotube is close in its magnitude to that previously reported for hybrid plasmonic nanostructures artificially fabricated of organic semiconductors on metallic films. We expect this effect to open up paths to new tunable optoelectronic device applications of semiconducting carbon nanotubes.
