description: در جهان امروز که کارشناسان به دنبال مدل های تازه ای برای رشد و توسعه اقتصادی و مبارزه با تغییرات آب و هوایی هستند، مدیریت پایدار دیگر یک گزینه انتخابی نیست بلکه شرطی اساسی برای بقا و موفقیت محسوب می شود. از دید کارشناسان صنعت گردشگری، ایران از توسعه ای که شایسته آن است برخوردار نبوده است. از دلایل آن می توان به آماده نبودن بسترهای اقتصادی مناسب در ایران برای جذب سرمایه گذاری در ساخت هتل و سایر منابع جانبی این حوزه اشاره کرد.صنعت گردشگری به عنوان یکی از بزرگترین هدایت کنندگان اشتغال و توسعه جهانی، نقش مهمی در رشد اقتصاد محلی و بهبود محیط زیست و شرایط زندگی دارد این صنعت به تنهایی مسیول پنج درصد دی اکسید کربن و گازهای گلخانه ای تولید شده در جهان است که از این میزان یک درصد متعلق به هتلها و دیگر انواع اقامتگاهها است. به همین دلیل صنعت گردشگری باید نسبت به بهینه سازی مصرف انرژی مسیولانه رفتار کند و دستیابی به توسعه پایدار رادر اولویت تمامی برنامه هایش قرار دهد. از این رو شهر مشهد که سالانه میزبان 15 میلیون گردشگر است، در این میان از اهمیت زیادی برخوردار است.

description: Recently, Takamoto et al. [Nat. Photonics (2020), https://doi.org/10.1038/s41566-020-0619-8] measured with a very high precision the time dilation at different altitudes by using two sophisticated optical lattice clocks respectively at the bottom and at the top floors of the Tokyo Skytree building. They concluded that general theory of relativity (GTR) successfully passed their test. We have yet to report that YARK (Yarman-Arik-Kholmetskii) theory of gravitation — whose total energy expression versus that of GTR was delineated in a previous submission [Yarman et al., PJSE (2018), https://sites.google.com/site/pjsciencea/2018/november-v-4-n-8] — passes the test just as easily when considering only the effect of gravity. That is to say, a precision of about 15,000 times more than the present one is needed to discern the difference between the predictions of the two theories under the given circumstances. We moreover have to add that the two theories in consideration are built on totally different frameworks. In particular, the time dilation in question is due to curvature in GTR, whereas it is due to just energy conservation embodying the mass and energy equivalence of the special theory of relativity (STR) in YARK.

description: A detailed study of complex-space singularities of the two-dimensional incompressible Euler equation is performed in the short-time asymptotic régime when such singularities are very far from the real domain; this allows an exact recursive determination of arbitrarily many spatial Fourier coefficients. Using high-precision arithmetic we find that the Fourier coefficients of the stream function are given over more than two decades of wavenumbers by $\hat F(\k) = C(θ) k^{-α} \ue ^ {-k δ(θ)}$, where $\k = k(\cos θ, \sin θ)$. The prefactor exponent $α$, typically between 5/2 and 8/3, is determined with an accuracy better than 0.01. It depends on the initial condition but not on $θ$. The vorticity diverges as $s^{-β}$, where $α+β= 7/2$ and $s$ is the distance to the (complex) singular manifold. This new type of non-universal singularity is permitted by the strong reduction of nonlinearity (depletion) which is associated to incompressibility. Spectral calculations show that the scaling reported above persists well beyond the time of validity of the short-time asymptotics. A simple model in which the vorticity is treated as a passive scalar is shown analytically to have universal singularities with exponent $α=5/2$.

description: There is ongoing interest in the global entropy production rate as a climate diagnostic and predictor, but progress has been limited by ambiguities in its definition; different conceptual boundaries of the climate system give rise to different internal production rates. Three viable options are described, estimated and investigated here, two of which -- the material and the total radiative (here 'planetary') entropy production rates -- are well-established and a third which has only recently been considered but appears very promising. This new option is labelled the 'transfer' entropy production rate and includes all irreversible processes that transfer heat within the climate, radiative and material, but not those involved in the exchange of radiation with space. Estimates in three model climates put the material rate in the range $27$-$48$ mW/m$^2$K, the transfer rate $67$-$76$ mW/m$^2$K, and the planetary rate $1279$-$1312$ mW/m$^2$K. The climate-relevance of each rate is probed by calculating their responses to climate changes in a simple radiative-convective model. An increased greenhouse effect causes a significant increase in the material and transfer entropy production rates but has no direct impact on the planetary rate. When the same surface temperature increase is forced by changing the albedo instead, the material and transfer entropy production rates increase less dramatically and the planetary rate also registers an increase. This is pertinent to solar radiation management as it demonstrates the difficulty of reversing greenhouse gas-mediated climate changes by albedo alterations. It is argued that the transfer perspective has particular significance in the climate system and warrants increased prominence.

description: Within $R^2$ gravity, we study the linear stability of strongly gravitating spherically symmetric configurations supported by a polytropic fluid. All calculations are carried out in the Jordan frame.

description: Segregation by race, ethnicity and income is a persistent feature of U.S. cities and communities, and ethnic enclaves have formed ever since immigration became more diverse. For low-skilled immigrants in particular, settling in an ethnic enclave may offer important opportunities and facilitate coping with the new environment. However, immigrant enclaves may also foster occupational segregation and retard assimilation, with the willingness to invest in language acquisition playing a key role. This paper expands on earlier work focusing on the linkage between spatial segregation and language acquisition. Using data from the 2000 U.S. Census the study stratifies immigrants by their location in one of four metropolitan areas by educational attainment and national origin in order to determine the effect of these individual characteristics on English proficiency. The probability of speaking English was found to vary across the four locales and educational attainment. Language acquisition was highest in the metropolitan area where the immigrant share is smallest, and is increasing in educational attainment.

description: We study the energy spectrum of magnons in a ferromagnet with topologically nontrivial magnetization profile. In the case of inhomogeneous magnetization corresponding to a metastable state of ferromagnet, the spin-wave equation of motion acquires a gauge potential leading to a Berry phase for the magnons propagating along a closed contour. The effect of magnetic anisotropy is crucial for the Berry phase: we show that the anisotropy suppresses its magnitude, which makes the Berry phase observable in some cases, similar to the Aharonov-Bohm effect for electrons. For example, it can be observed in the interference of spin waves propagating in mesoscopic rings. We discuss the effect of domain walls on the interference in ferromagnetic rings, and propose some experiments with a certain geometry of magnetization. We also show that the nonvanishing average topological field acts on the magnons like a uniform magnetic field on electrons. It leads to the quantization of the magnon spectrum in the topological field.

Separate Universe calibration of the dependence of halo bias on cosmic web anisotropy

description: We use the Separate Universe technique to calibrate the dependence of linear and quadratic halo bias $b_1$ and $b_2$ on the local cosmic web environment of dark matter haloes. We do this by measuring the response of halo abundances at fixed mass and cosmic web tidal anisotropy $α$ to an infinite wavelength initial perturbation. We augment our measurements with an analytical framework developed in earlier work which exploits the near-Lognormal shape of the distribution of $α$ and results in very high precision calibrations. We present convenient fitting functions for the dependence of $b_1$ and $b_2$ on $α$ over a wide range of halo mass for redshifts $0\leq z\leq1$. Our calibration of $b_2(α)$ is the first demonstration to date of the dependence of non-linear bias on the local web environment. Motivated by previous results which showed that $α$ is the primary indicator of halo assembly bias for a number of halo properties beyond halo mass, we then extend our analytical framework to accommodate the dependence of $b_1$ and $b_2$ on any such secondary property which has, or can be monotonically transformed to have, a Gaussian distribution. We demonstrate this technique for the specific case of halo concentration, finding good agreement with previous results. Our calibrations will be useful for a variety of halo model analyses focusing on galaxy assembly bias, as well as analytical forecasts of the potential for using $α$ as a segregating variable in multi-tracer analyses.

description: The objective of this study was to determine the impact of bean grain quality characteristics on market price. The data was collected from retail markets in Tanzania. Hedonic pricing provides a statistical estimate of premiums and discounts. Implications for development of bean markets include - i) extension agents should identify cost-effective ways to educate producers on targeting urban market niches based on consumer preferences for varieties, ii) breeding for bruchid resistant beans and use of appropriate storage technologies would alleviate the problems of storage damage, and iii) requiring a portfolio of grain quality characteristics to fit consumer preferences in local markets.

A comb-like array of coherent atomic beams is generated by outcoupling atoms from distinct Bose-Einstein condensates confined in the independent sites of a mesoscopic optical lattice. The observed interference signal arises from the spatial beating of the overlapped atom laser beams, which is sampled over a vertical region corresponding to 2 ms of free fall time. The average relative de Broglie frequency of the atom lasers was measured.

Plasmonic Instabilities in Two-dimensional Electron Channels of Variable Width

description: Understanding of fundamental physics of plasmonic instabilities is the key issue for the design of a new generation of compact electronic devices required for numerous THz applications. Variable width plasmonic devices have emerged as potential candidates for such an application. The analysis of the variable width plasmonic devices presented in this paper shows that these structures enable both the Dyakonov-Shur instability (when the electron drift velocity everywhere in the device remains smaller than the plasma velocity) and the "plasmonic boom" instability that requires drift velocity exceeding the plasma velocity in some of the device sections. For symmetrical structures, the drifting current could be provided by an RF signal leading to RF to THz and THz to RF frequency conversion using the source and drain antennas and reducing losses associated with ohmic contacts. We show that narrow regions protruding from the channel ("plasmonic stubs") could control and optimize boundary conditions at the contacts and/or at the interfaces between different device sections. These sections could be combined into plasmonic crystals yielding enhanced power and a better impedance matching. The mathematics of the problems is treated using the transmission line analogy. We show that the combination of the stubs and the variable width channels is required for the instability rise in an optimized plasmonic crystal. Our estimates show that THz plasmonic crystal oscillators could operate at room temperature.

Anion vacancies as a source of persistent photoconductivity in II-VI and chalcopyrite semiconductors
Creators: name: Lany, S.

Year: 2005
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Using first-principles electronic structure calculations we identify the anion vacancies in II-VI and chalcopyrite Cu-III-VI2 semiconductors as a class of intrinsic defects that can exhibit metastable behavior. Specifically, we predict persistent electron photoconductivity (n-type PPC) caused by the oxygen vacancy VO in n-ZnO, and persistent hole photoconductivity (p-type PPC) caused by the Se vacancy VSe in p-CuInSe2 and p-CuGaSe2. We find that VSe in the chalcopyrite materials is amphoteric having two "negative-U" like transitions, i.e. a double-donor transition e(2+/0) close to the valence band and a double-acceptor transition e(0/2-) closer to the conduction band. We introduce a classification scheme that distinguishes two types of defects (e.g., donors): type-alpha, which have a defect-localized-state (DLS) in the gap, and type-beta, which have a resonant DLS within the host bands (e.g., conduction band). In the latter case, the introduced carriers (e.g., electrons) relax to the band edge where they can occupy a perturbed-host-state (PHS). Type alpha is non-conducting, whereas type beta is conducting. We identify the neutral anion vacancy as type-alpha and the doubly positively charged vacancy as type-beta. We suggest that illumination changes the charge state of the anion vacancy and leads to a crossover between alpha- and beta-type behavior, resulting in metastability and PPC. In CuInSe2, the metastable behavior of VSe is carried over to the (VSe-VCu) complex, which we identify as the physical origin of PPC observed experimentally. We explain previous puzzling experimental results in ZnO and CuInSe2 in the light of this model.

description: The evolution of sustained plant–animal interactions depends critically upon genetic variation in the fitness benefits from the interaction. Genetic analyses of such interactions are limited to a few model systems, in part because genetic variation may be absent or the interacting species may be experimentally intractable. Here, we examine the role of sperm-dispersing microarthropods in shaping reproduction and genetic variation in mosses. We established experimental mesocosms with known moss genotypes and inferred the parents of progeny from mesocosms with and without microarthropods, using a pooled sequencing approach. Moss reproductive rates increased fivefold in the presence of microarthropods, relative to control mesocosms. Furthermore, the presence of microarthropods increased the total number of reproducing moss genotypes, and changed the rank-order of fitness of male and female moss genotypes. The genotypes that reproduced most often did not produce sporophytes that produced the most spores, highlighting the challenge of defining fitness in mosses. Nevertheless, these results demonstrate that microarthropods provide a fitness benefit for mosses, and highlight the potential for biotic dispersal agents to alter fitness among moss genotypes in this plant–animal interaction.

Pathogenesis of coxasackievirus B3 induced myocarditis and systemic disease : viral localization, direct injury and activation of host cell death machinery
Creators: name: Carthy, Christopher Michael
Publisher: name: University of British Columbia
Year: 2009

description: Coxsackievirus B3, a cytopathic virus in the family Picornaviridae, induces degenerative changes in host cell morphology following infection. Work presented in this thesis will examine the nature of these cytopathic changes in vivo in myocarditis susceptible and resistant mice, and in vitro in HeLa cells, a common cell line used to dissect coxsackievirus lifecycle and host interaction. In mice, CVB3 infection caused a widespread systemic disease including infection of the heart, pancreas, liver, brain, spleen, salivary glands, lung and kidney. Adjacent sections stained for viral RNA by in situ hybridisation and tissue injury by TUNEL have demonstrated that infected cells are directly injured prior to activation of the cellular arm of the immune system. In the lymphoid organs, there is increased apoptosis that may be responsible for the lymphoid involution characteristically noted early following infection. The association of virus with lymphocytes may interfere with the normal immune response. There is a depression of IL-2 and IL-4 protein levels in infected mice as compared to sham treated animals. In HeLa cells, multiple caspases are processed and activated following the release of cytochrome c from the intermitochondrial space to the cytosol. Caspase-specific substrates are cleaved, but these events are not solely responsible for the degenerative morphologic changes noted following infection. Using ZVAD.fmk or cells stably transfected with Bcl-2 and Bcl-x[sub L], it was further demonstrated that cytopathic effect is not caused by caspase activation. Activation of caspases, however, plays a role in loss of cell viability and the release of the progeny virus from within the cell. Cytopathic effect is probably due to viral protease mediated degradation of host cell structural proteins including focal adhesion kinase that is cleaved by a protease not inhibited by ZVAD.fmk. cDNA microarrays were used to profile the host gene response in the myocardium at days 3, 9, and 30 post infection to dissect the various stages of disease progression, including, direct viral injury, host specific immune response and viral clearance, and late stage cardiac remodelling. From a limited repertoire of genes, we identified 169 known genes that were significantly up or down regulated at one or more of the three timepoints. This study was one of the first in vivo gene expression models examining cardiac disease progression in mice over time. Direct extensions of this thesis includes interrogation of direct host and viral protein-protein interactions, examination of mitogen activated protein kinase signalling pathways and relationship to cell viability and virus replication, and further dissection of the effect of viral proteases on degradation of various host cellular proteins and effect on host cell homeostasis.

The gain from a decision depends on choosing the best policy given the state of the world, which is uncertain. The output of policy research is a conclusion about that state. Taking a Bayesian approach, the ex ante value of a research program is estimated from information about decisionmakers’ prior probabilities of the state of the world and the likelihood of correct and incorrect research findings. Case studies of U.S. agricultural policy research cover consequences of trade liberalization, farm commodity program analysis, effects of publicly supported commodity promotion, and the value of publicly funded crop forecasting and research on agricultural technology. The quantification of the value of these research programs is highly conjectural, but consideration of their likely magnitude, as compared to the costs of the research, suggests that there are substantial net social gains.

description: We study the model of a noninteracting spinless electron gas confined to the two-dimensional localized surface of a cone in the presence of external magnetic fields. The localized region is characterized by an annular radial potential. We write the Schrödinger equation and use the thin-layer quantization procedure to calculate the wavefunctions and the energy spectrum. In such a procedure, it arises a geometry induced potential, which depends on both the mean and the Gaussian curvatures. Nevertheless, since we consider a ring with a mesoscopic size, the effects of the Gaussian curvature on the energy spectrum are negligible. The magnetization and the persistent current are analyzed. In the former, we observed the Aharonov-Bohm (AB) and de Haas-van Alphen (dHvA) types oscillations. In the latter, it is observed only the AB type oscillations. In both cases, the curvature increases the amplitude of the oscillations.

description: The objective of this report is to publish a monthly forecasting tool of the U.S. dairy industry. This model forecasts the milk supply as well as the supply and demand for American cheese, Other cheese, butter, nonfat dry milk, and dry whey. Trade is presently exogenous to the model, but can be endogenized at a later date. The principal use of the model will be for forecasting purposes, thus we settled on a monthly frequency for the data. We delve into the complexities of the U.S. dairy industry using rich data sources. Our objective is clearly focused on developing an initial forecasting tool.

description: The objective of this study was to determine the impact of bean grain quality characteristics on market price. The data was collected from retail markets in Tanzania. Hedonic pricing provides a statistical estimate of premiums and discounts. Implications for development of bean markets include : i) extension agents should identify cost-effective ways to educate producers on targeting urban market niches based on consumer preferences for varieties, ii) breeding for bruchid resistant beans and use of appropriate storage technologies would alleviate the problems of storage damage, and iii) requiring a portfolio of grain quality characteristics to fit consumer preferences in local markets.

description: We introduce a new scheme to design optical microcavities supporting high-Q modes with unidirectional light emission. This is achieved by coupling a low-Q mode with unidirectional emission to a high-Q mode. The coupling is due to enhanced dynamical tunneling near an avoided resonance crossing. Numerical results for a microdisk with a suitably positioned air hole demonstrate the feasibility and the potential of this concept.

description: The Nelson-Seiberg theorem relates R-symmetries to F-term supersymmetry breaking, and provides a guiding rule for new physics model building beyond the Standard Model. A revision of the theorem gives a necessary and sufficient condition to supersymmetry breaking in models with polynomial superpotentials. This work revisits the theorem to include models with nonpolynomial superpotentials. With a generic R-symmetric superpotential, a singularity at the origin of the field space implies both R-symmetry breaking and supersymmetry breaking. We give a generalized necessary and sufficient condition for supersymmetry breaking which applies to both perturbative and nonperturbative models.

description: Within the framework of a Kaluza-Klein theory, we provide the geometrization of a generic (Abelian and non-Abelian) gauge coupling, which comes out by choosing a suitable matter fields dependence on the extra-coordinates. We start by the extension of the Nother theorem to a multidimensional spacetime being the direct sum of a 4-dimensional Minkowski space and of a compact homogeneous manifold (whose isometries reflect the gauge symmetry); we show, how on such a ``vacuum'' configuration, the extra-dimensional components of the field momentum correspond to the gauge charges. Then we analyze the structure of a Dirac algebra as referred to a spacetime with the Kaluza-Klein restrictions and, by splitting the corresponding free-field Lagrangian, we show how the gauge coupling terms outcome.

Low Energy Spread Attosecond Bunching and Coherent Electron Acceleration in Dielectric Nanostructures

description: We demonstrate a compact technique to compress electron pulses to attosecond length, while keeping the energy spread reasonably small. The technique is based on Dielectric Laser Acceleration (DLA) in nanophotonic silicon structures. Unlike previous ballistic optical microbunching demonstrations, we use a modulator-demodulator scheme to compress phase space in the time and energy coordinates. With a second stage, we show that these pulses can be coherently accelerated, producing a net energy gain of $1.5\pm0.1$ keV, which is significantly larger than the remaining energy spread of $0.88 \,_{-0.2}^{+0.0}$ keV FWHM. We show that by linearly sweeping the phase between the two stages, the energy spectrum can be coherently moved in a periodic manner, while keeping the energy spread roughly constant. After leaving the buncher, the electron pulse is also transversely focused, and can be matched into a following accelerator lattice. Thus, this setup is the prototype injector into a scalable DLA based on Alternating Phase Focusing (APF).

description: Sustainable and low-cost technologies for carbon-based nanomaterials are required for wastewater treatment. Two graphitic precursors (graphite flakes and graphite powder) were tested to synthesize graphene-related materials using mechanochemical treatment. For comparison, chemical graphite oxide (GO imp) was synthesized. The pristine and final products were characterized by SEM-EDX, particle size distribution, elemental analysis, surface area, DTA-TG and Raman spectra. Oxygen/carbon ratios of the mechanochemical and chemical routes were detected by EDX and confirmed using elemental analysis. The surface area increased from ~1 up to 666 and 328 m2 g−1 for graphite flakes and graphite powder at 24 h of mechanochemical treatment, respectively. However, the surface area for GO imp reached 157 m2 g−1. The removal of methylene blue, acid orange 7 and bisphenol A with the mechanochemical synthesized graphite oxides reached >93.8% at 30 min. The adsorption mechanism is mainly governed by π − π interactions and hydrogen bonding.

description: Fourteen long term side-by-side tillage practice experiments were studied to analyze if no-tillage yields improved through time allowing incentives to decline. In the majority of cases, no significant increase in no-till yield is evident. Incentives may need to be permanent if switched acres are to remain using no-tillage practices.
