DEVELOPMENT OF SERVICE IN ECOLOGICAL AND RELIGIOUS TOURISM OBJECTS AS EXAMPLE, CHOR-CHINAR ECOLOGICAL-RELIGIOUS COMPLEX, URGUT DISTRICT IN SAMARKAND REGION.
Creators: name: Gafforova, Shahrizoda
Publisher: name: Zenodo
Year: 2024

description: This article examines the impact of service quality on tourist satisfaction and loyalty at the Chor-chinor religious and ecological site. The study emphasizes the importance of enhancing services such as transport, dining, and auxiliary facilities to meet tourists’ expectations. It suggests that the current marketing efforts to attract tourists are insufficient, and basic services need improvement. The findings indicate that improving service quality can lead to increased satisfaction and loyalty among visitors, ultimately benefiting the local economy and community.
Photospheric signatures imprinted on the gamma-ray burst spectra

Subjects: subject: Astrophysics (astro-ph)

description: A solution is presented for the spectrum of high-energy gamma-ray burst photons confined to a quasi-thermal baryonic photosphere. The solution is valid in the steady-state limit assuming the region under consideration is optically thick to the continuously injected photons. It is shown that for a high luminosity photosphere, the non-thermal electrons resulting from gamma-ray Compton cooling lose their energy by upscattering the soft thermalised radiation. The resulting spectral modifications offer the possibility of diagnosing not only the burst comoving luminosity but also the baryon load of the ejecta. This model leads to a simple physical interpretation of X-ray rich bursts and anomalous low-energy slopes.

description: It is shown that grey soliton dynamics in an one-dimensional trap can be treated as Landau dynamics of a quasi-particle. A soliton of arbitrary amplitude moves in the trapping potential without deformation of its density profile as a particle of mass $2m$. The dynamics in the local density approximation is shown to be consistent with the perturbation theory for dark solitons. Dynamics of a vortex ring in a trap is discussed qualitatively.

description: We use Langevin dynamics simulations to study dense 2d systems of particles with both size and energy polydispersity. We compare two types of bidisperse systems which differ in the correlation between particle size and interaction parameters: in one system big particles have high interaction parameters and small particles have low interaction parameters, while in the other system the situation is reversed. We study the different phases of the two systems and compare them to those of a system with size but not energy bidispersity. We show that, depending on the strength of interaction between big and small particles, cooling to low temperatures yields either homogeneous glasses or mosaic crystals.

description: We estimate determinants of growth among German dairy farms between 1997 und 2005 under the EU milk quota system. Higher milk yield per cow, more family labour, and higher milk prices increase the growth rate of growing farms, ceteris paribus. Older growing farmers tend to grow at lower rates. In line with Weiss’ findings (1999) for Austrian farms, Gibrat’s Law of relative firm growth being independent of initial firm size does not hold for our subsample of farms growing in milk production, either: the growth rate is quite high for small farms and has a minimum for farms around 325,000 kg of initial quota. For the 16% of growing farms that have more initial quota the growth rate increases up to some out-of-sample maximum. We corrected for selection bias by means of a multinomial logit model which explains the choice among different growth regimes in more detail than the well-known Heckman procedure. In our case, e.g. age impacts the choice between growth and stagnation but not between growth and exiting from milk production; crop subsidies only influence the decision between growth and exiting from milk production but not the decision between growth and decline or stagnation.
Projective and amplified symmetries in metric-affine theories

description: In this paper we extend the projective symmetry of the full metric-affine Einstein-Hilbert theory to a new symmetry transformation in the space of affine connections called the amplified symmetry. We prove that the Lagrangian of the Standard Model of particle physics is invariant under this new symmetry. We also show that the gravitational Lagrangian can be modified so that the amplified symmetry extends to the gravitational sector and hence to the whole action. The new theory so constructed is shown to be dynamically equivalent to Einstein-Cartan's though genuinely metric-affine.

description: This article is concerned with the methodological question of frontier production functions estimation for agriculture, and the appropriateness of regression quantiles, as a useful semi-parametric approach. Better insights are reached using the proposed methodology that provides robust farm efficiency scores estimates. Using the 2007 Farm Accountancy Data Network (FADN) data for Greece, analysis shows that the distribution of efficiency scores is closer to normality when employing regression quantiles, while underestimation of efficiency obtained by other parametric or deterministic methods based on the conditional mean can be avoided. The results further suggest that government support aimed at enhancing farms viability should be directed towards payments decoupled from output or prices, as well as rural development payments that affect productivity in a uniform way.

description: We construct a class of Finsler metrics in three-dimensional space such that all their geodesics are lines, but not all planes are extremal for their Hausdorff area functionals. This shows that if the Hausdorff measure is used as notion of volume on Finsler spaces, then totally geodesic submanifolds are not necessarily minimal, filling results such as those of S. Ivanov do not hold, and integral-geometric formulas do not exist. On the other hand, using the Holmes-Thompson definition of volume, we prove a general Crofton formula for Finsler spaces and give an easy proof that their totally geodesic hypersurfaces are minimal.

description: In a standard theory of the formation of the planets in our Solar System, terrestrial planets and cores of gas giants are formed through accretion of kilometer-sized objects (planetesimals) in a protoplanetary disk. Gravitational $N$-body simulations of a disk system made up of numerous planetesimals are the most direct way to study the accretion process. However, the use of $N$-body simulations has been limited to idealized models (e.g. perfect accretion) and/or narrow spatial ranges in the radial direction, due to the limited number of simulation runs and particles available. We have developed new $N$-body simulation code equipped with a particle-particle particle-tree (${\rm P^3T}$) scheme for studying the planetary system formation process: GPLUM. For each particle, GPLUM uses the fourth-order Hermite scheme to calculate gravitational interactions with particles within cut-off radii and the Barnes-Hut tree scheme for particles outside the cut-off radii. In existing implementations, ${\rm P^3T}$ schemes use the same cut-off radius for all particles, making a simulation become slower when the mass range of the planetesimal population becomes wider. We have solved this problem by allowing each particle to have an appropriate cut-off radius depending on its mass, its distance from the central star, and the local velocity dispersion of planetesimals. In addition to achieving a significant speed-up, we have also improved the scalability of the code to reach a good strong-scaling performance up to 1024 cores in the case of $N=10^6$.

description: The impact of sectoral or economy wide policy scenarios is often of strong political and public interest, yet it is a scientific challenge. When analyzing different levels of aggregation, the use of single models may not be sufficient. In this paper we establish an interface between the European Simulation Model (ESIM) and the Farm Modelling Information System (FARMIS). The linkage of the two models allows us to quantify adjustment processes both at the sectoral level and at the farm group level for the German agricultural sector. Different liberalization scenarios are presented and compared to a reference scenario. The abolishment of market price support leads to a reduction of farm incomes, especially if direct payments are also reduced. The low absolute level of return to labor, particularly in grazing livestock farms, suggests strong changes in farm structure as well as the farm input industry in Germany under the full liberalization scenario.

description: The paper analyses the governance choices in production quota with the Flemish nutrient production rights as a case. A static model of quota trade in the short run shows the inefficiency of discrete non-auctioned trade with fixed transaction costs. This model also shows that an obligation to quota sellers to stop their production stimulates structural change. A dynamic model of trade indicates that the measures taken to prevent speculative behaviour causes inefficiencies and stimulates overuse of quota if the penalties are too low. Finally, the dynamic model indicates that a flat rate reduction on traded quota combined with too low penalties for overuse stimulate the total production.

description: Recently, natural van der Waals heterostructures of (MnBi2Te4)m(Bi2Te3)n have been theoretically predicted and experimentally shown to host tunable magnetic properties and topologically nontrivial surface states. In this work, we systematically investigate both the structural and electronic responses of MnBi2Te4 and MnBi4Te7 to external pressure. In addition to the suppression of antiferromagnetic order, MnBi2Te4 is found to undergo a metal-semiconductor-metal transition upon compression. The resistivity of MnBi4Te7 changes dramatically under high pressure and a non-monotonic evolution of \r{ho}(T) is observed. The nontrivial topology is proved to persists before the structural phase transition observed in the high-pressure regime. We find that the bulk and surface states respond differently to pressure, which is consistent with the non-monotonic change of the resistivity. Interestingly, a pressure-induced amorphous state is observed in MnBi2Te4, while two high pressure phase transitions are revealed in MnBi4Te7. Our combined theoretical and experimental research establishes MnBi2Te4 and MnBi4Te7 as highly tunable magnetic topological insulators, in which phase transitions and new ground states emerge upon compression.

The effect of oxygen and carbon dioxide on the diving behaviour and cardiac physiology of lesser scaup ducks (aythya affinis)
Creators: name: Borg, Kim A.
Publisher: name: University of British Columbia
Year: 2009

description: The present study was designed to determine the relative influence of oxygen (O₂) and carbon dioxide (CO₂) on the cardiovascular and behavioral adjustments during voluntary diving in lesser scaup ducks. Of particular interest was how these animals allocate time during the dive cycle (travel time, foraging time and surface time) in response to various levels of inspired O₂ and CO₂ during short and long horizontal dives that are energetically more costly than vertical dives. Heart rate was monitored to determine the influence of peripheral chemoreceptors on cardiovascular control during voluntary dives as well as during dives when the animals were temporarily trapped underwater. Compared with normoxia, hyperoxia (50% O₂) exposure significantly increased dive duration in long dives, whereas severe hypoxia (9%) exposure significantly decreased dive time in both short and long dives. Hypercapnia (5%) had no effect on dive duration, but significantly increased surface interval duration. Mean dive heart rate during short dives (211.8 ± 6.9 beats min⁻¹) was significantly higher than long dives (179.6 ± 5.0 beats min⁻¹) although heart rate during all dives remained above resting levels. Heart rate during diving was unaffected in response to hyperoxia and hypercapnia during both short and long dives, but gradually declined in long dives after severe hypoxia exposure. A faster developing bradycardia to 90 beats min⁻¹ at the end of short dives and to 70 beats min⁻¹ at the end of long dives was evoked when the animals were trapped underwater. There were no significant differences in the response between trap dives after normoxia or hyperoxia. A model of oxygen store utilization during a voluntary dive quantified the critical Pa[sub O₂] that necessitates cardiovascular adjustments in order to meet the metabolic needs of the tissues. During severe hypoxia, the critical Pa[sub O₂] of 21 mmHg was reached 19 seconds into theoretical dives which corresponded with initiation of bradycardia in our severe hypoxia trials. The results suggest that O₂ and CO₂ levels in lesser scaup ducks are managed through changes in diving behavior without any major cardiovascular adjustments occurring throughout the dive. When the animals are pushed to the extremes of their endurance and Pa[sub O₂] levels drop to threshold levels, a chemoreceptor induced bradycardia is evoked to conserve the remaining oxygen in the body.

description: We analyze the performance of a planar lens based on realistic negative index material in a generalized geometry. We demonstrate that the conventional superlens design (where the lens is centered between the object and the image) is not optimal from the resolution point-of-view, develop an analytical expression for the resolution limit of a generalized lens, use it to find the optimum lens configuration, and calculate the maximum absorption practical nearfield superlenses may have. We demonstrate that in contrast to the conventional superlens picture, planar imaging is typically accompanied by excitation of surface waves at both interfaces of the lens.

description: Purpose: Despite the recognition that family-centered services are best practice in augmentative and alternative communication services, many speech-language pathologists (SLPs) are lacking in their acquisition and implementation of family-centered skills. The purpose of this study was to evaluate the effects of online instruction in a family-centered, relational skills strategy on preservice SLPs use of family-centered skills.Method: A switching replications design was used to evaluate the effects of an online training on the use of family-centered behaviors by 15 preservice SLPs who were randomly assigned to two groups. The online training taught the students a four-step relational skills strategy (summarized by the acronym LAFF): (a) Listen, empathize, and communicate respect; (b) Ask questions; (c) Focus on the issues; and (d) Find a first step. Participants were videotaped during interactions with simulated parents before and after the training.Results: After an average of 61 min of instruction via the online module, all of the preservice SLPs significantly improved their demonstration of relational skills. Additionally, one parent of a child who used augmentative and alternative communication viewed the video recordings and chose 14 of the 15 postinstruction role plays as more family-centered.Conclusion: The findings from this study provide support for the use of an online environment to teach preservice SLPs family-centered relational skills. In order to prepare future SLPs and ensure the delivery of family-centered services, future research is necessary, including investigations to determine whether other family-centered skills can be effectively taught through an online environment.

description: Forecasting the formation and development of clouds is a central element of modern weather forecasting systems. Incorrect clouds forecasts can lead to major uncertainty in the overall accuracy of weather forecasts due to their intrinsic role in the Earth's climate system. Few studies have tackled this challenging problem from a machine learning point-of-view due to a shortage of high-resolution datasets with many historical observations globally. In this paper, we present a novel satellite-based dataset called ``CloudCast''. It consists of 70,080 images with 10 different cloud types for multiple layers of the atmosphere annotated on a pixel level. The spatial resolution of the dataset is 928 x 1530 pixels (3x3 km per pixel) with 15-min intervals between frames for the period 2017-01-01 to 2018-12-31. All frames are centered and projected over Europe. To supplement the dataset, we conduct an evaluation study with current state-of-the-art video prediction methods such as convolutional long short-term memory networks, generative adversarial networks, and optical flow-based extrapolation methods. As the evaluation of video prediction is difficult in practice, we aim for a thorough evaluation in the spatial and temporal domain. Our benchmark models show promising results but with ample room for improvement. This is the first publicly available global-scale dataset with high-resolution cloud types on a high temporal granularity to the authors' best knowledge.

description: Resonances with their short life time and strong coupling to the dense and hot medium are suggested as a signature of the early stage of the fireball created in a heavy ion collision \cite{rap00,lut01,lut02}. The comparison of resonances with different lifetimes and quark contents may give information about time evolution and density and temperature of during the expanding of fireball medium. Resonances in elementary reactions have been measured since 1960. Resonance production in elementary collisions compared with heavy ion collisions where we expect to create a hot and dense medium may show the direct of influence of the medium on the resonances. This paper shows a selection of the recent resonance measurements from SPS and RHIC heavy ion colliders.

description: The decarbonization of energy systems has led to a fundamental change in their topology since generation is shifted to locations with favorable renewable conditions. In planning, this change is reflected by applying optimization models to regions within a country to optimize the distribution of generation units and to evaluate the resulting impact on the grid topology. This paper proposes a globally applicable framework to find a suitable regionalization for energy system models with a data-driven approach. Based on a global, spatially resolved database of demand, generation, and renewable profiles, hierarchical clustering with fine-tuning is performed. This regionalization approach is applied by modeling the resulting regions in an optimization model including a synthesized grid. In an exemplary case study, South Africa’s energy system is examined. The results show that the data-driven regionalization is beneficial compared to the common approach of using political regions. Furthermore, the results of a modeled 80% decarbonization until 2045 demonstrate that the integration of renewable energy sources fundamentally changes the role of regions within South Africa’s energy system. Thereby, the electricity exchange between regions is also impacted, leading to a different grid topology. Using clustered regions improves the understanding and analysis of regional transformations in the decarbonization process.

PyCDFT provides an object-oriented, customizable implementation of CDFT, and allows for both single-point self-consistent-field calculations and geometry optimizations. PyCDFT is designed to interface with existing density functional theory (DFT) codes to perform CDFT calculations where constraint potentials are added to the Kohn-Sham Hamiltonian. Here we demonstrate the use of PyCDFT by performing calculations with a massively parallel first-principles molecular dynamics code, Qbox, and we benchmark its accuracy by computing the electronic coupling between diabatic states for a set of organic molecules. We show that PyCDFT yields results in agreement with existing implementations and is a robust and flexible package for performing CDFT calculations. The program is available at https://github.com/hema-ted/pycdft/.

description: In this work, we present and analyze a mathematical model for tumor growth incorporating ECM erosion, interstitial flow, and the effect of vascular flow and nutrient transport. The model is of phase-field or diffused-interface type in which multiple phases of cell species and other constituents are separated by smooth evolving interfaces. The model involves a mesoscale version of Darcy's law to capture the flow mechanism in the tissue matrix. Modeling flow and transport processes in the vasculature supplying the healthy and cancerous tissue, one-dimensional (1D) equations are considered. Since the models governing the transport and flow processes are defined together with cell species models on a three-dimensional (3D) domain, we obtain a 3D-1D coupled model. We show some mathematical results on the existence of weak solutions. Furthermore, simulation results are presented illustrating the evolution of tumors and the effects of ECM erosion.

The further and vocational education sector in Ireland has been perceived by some stakeholders as being less clearly defined and of lower status than higher education (ESRI 2014). This paper sets out to identify the key milestones, methodologically through a historical lens, in the evolution of education and skills policy in Ireland, with an emphasis on the balance of education provision from an equity perspective for TVET and VET learners. The developments of the nineteenth century laid the tentative foundations for the modern Further Education and Training (FET) sector and were built upon in the early years after Irish independence with the establishment of the Vocational Education Committee (VEC) system. Johnstone (1999) argues that vocational education is in direct opposition to liberal education, in that the ultimate justification for education within the vocational paradigm is to get people ready for the world of work. Though the line between further and vocational education in Ireland has often been blurred, this paper examines the influences, development, and changes in Vocational and Further Educational Policy in Ireland since the inception of the Irish Free State in 1922 up to 2019. The paper concludes by highlighting how the historical barriers to development of the sector were clearly located within the Irish State. From and equality of opportunity perspective the Catholic Church’s opposition,  in the early years of the VEC system, thwarted its development, and prevented it from “achieving its full potential” (Girvin, 2002: 69). The scholarly relevance of the paper highlights the context of the historical significance of these developments. The perceived neglect by the Irish Department of Education (until recent times) was a further equity barrier for learners and was in many ways may have aided the perception of the low standing of Further Education, TVET and VET within Irish society. Significantly, further education in the Irish State has now been placed within the framework of the tertiary education sector. The latter part of the paper pays attention to the development of policy in recent years focusing on further and vocational education and training (with an emphasis on skills policy) leading to the launch of Ireland first Further Education and Training strategy (2014-2019).
The diffuse supernova neutrino flux, supernova rate and SN1987A

description: I calculate the diffuse flux of electron antineutrinos from all supernovae using the information on the neutrino spectrum from SN987A and the information on the rate of supernovae from direct supernova observations. The interval of flux allowed at 99 % confidence level is 0.05 - 0.35 cm^-2 s ^-1 above the SuperKamiokande (SK) energy cut of 19.3 MeV. This result is at least a factor of 4 smaller than the current SK upper limit of 1.2 cm^-2 s ^-1, thus motivating the experimental efforts to lower the detection energy threshold or to upgrade to higher volumes. A Megaton water Cherenkov detector with 90 % efficiency would record 2 - 44 inverse beta decay events a year depending on the energy cut.
description: LaTeX, 28 pages, 8 figures. Major improvements: qualitative arguments replaced with full statistical analysis; direct measurements of the supernova rate used; title slightly modified for consistency and figures added. Noticeable changes in the results

description: We study the asymptotic behaviour, in the sense of $Γ$-convergence, of a thin incompressible magnetoelastic plate, as its thickness goes to zero. We focus on the linearized von Kármán regime. The model features a mixed Eulerian-Lagrangian formulation, as magnetizations are defined on the deformed confguration.

description: Studying the ambient solar wind, a continuous pressure-driven plasma flow emanating from our Sun, is an important component of space weather research. The ambient solar wind flows in interplanetary space determine how solar storms evolve through the heliosphere before reaching Earth, and especially during solar minimum are themselves a driver of activity in the Earth's magnetic field. Accurately forecasting the ambient solar wind flow is therefore imperative to space weather awareness. Here we present a machine learning approach in which solutions from magnetic models of the solar corona are used to output the solar wind conditions near the Earth. The results are compared to observations and existing models in a comprehensive validation analysis, and the new model outperforms existing models in almost all measures. In addition, this approach offers a new perspective to discuss the role of different input data to ambient solar wind modeling, and what this tells us about the underlying physical processes. The final model discussed here represents an extremely fast, well-validated and open-source approach to the forecasting of ambient solar wind at Earth.

description: Field data are used to illustrate that, other things constant, regression results using Ordinary Least Squares (OLS) converge to Tobit estimates as the number of zeros in the regressand decrease. Tobit estimates are theoretically superior to OLS estimates when using censored data. However, if little difference exists between OLS and Tobit estimates, OLS may be operationally acceptable. OLS may even be optimal in a bounded rationality sense because the extra cost of using Tobit analysis may be less than the extra benefits from a very slight increase in accuracy.
Risk factors for drug resistant TB in British Columbia

description: Objectives: A) To investigate the epidemiological risk factors associated with resistance to antituberculosis drugs in British Columbia B) To determine if there are differences in risk factor characteristics among different categories of drug resistant (mono-drug, poly and multi-drug resistance) TB cases. Methods: The study was carried out in two phases. The first phase of the study was retrospective in design. The data examined in this study was collected by the division of TB control of British Columbia and was obtained from retrospective review of charts, prescriptions, files of the TB subjects or other clients who attended the provincial (BC) TB service. The second phase involved a matched case control study design (using a sample from the total study population). Cases were all resistant TB subjects while controls were selected randomly from the pool of sensitive subjects matched on age group and sex. Results: A total of 3041 TB subjects were eligible for this study over a period of 12 years (1990- 2001). Of those eligible, there were 295 (10%) resistant cases and 2746 (90%>) sensitive cases. The significant risk factors for drug resistance found in this study were immigration status, ethnicity, birth country, last country of residence, a history of previous TB, place of diagnosis and case category. With respect to immigration, foreign born people are four times more likely to present with drug resistance than the Canadian-born people. Among the ethnic groups, Chinese, Southeast Asian and the Rest of the Asian are two to three times more likely to present with drug resistance than Caucasians. According to birth country, people born in China, Southeast Asia, and other parts' of Asia were four times more likely to present with drug resistance than Canadian-born people. Subjects with a history of previous TB were twice as likely to present with drug resistance compared to the subjects without any history of previous TB. Subjects diagnosed outside of Canada were almost three times more likely to have drug resistance compared to the subjects diagnosed in Canada. Reactivated (relapsed) cases are almost three times as likely to present with drug resistance compared to the new cases. Conclusions: In brief, foreign born immigrants, patients with a history of previous TB and reactivated (relapsed) TB cases are at greater risk for TB drug resistance. Efforts should be made to prioritize the development and implementation of effective screening and treatment protocols for these high risk groups in order to avoid the emergence of further resistance tuberculosis.
On tachyon and sub-quantum phantom cosmologies

description: This paper deals with dark and phantom energy in the tachyon and sub-quantum models for dark energy. We obtain that the simplest condition for such a regime to occur in these scenarios is that the scalar field be Wick rotated to imaginary values which correspond to an axionic field classically. By introducing analytical expressions for the scale factor or the Hubble parameter that satisfy all constraint equations of the used models we show that such models describe universes which develop a big rip singularity in the finite future.
