Schemes and Mechanisms of Neutrino Mixings (Oscillations) and a Solution of the Sun Neutrinos Deficit Problem

description: Three schemes of neutrino mixings (oscillations) are proposed. The problems of origin of angle mixings, with the law of energy-momentum conservation and disintegration of neutrino as wave pocket are solved. These two schemes belong to mass mixings schemes, where mixing angles and oscillation lengths are expressed via elements of mass matrix. The third scheme belongs to the charge mixings scheme, where mixing parameters are expressed via neutrino weak charges, as it takes place in the vector dominance model. Using experiments we must decide which of these schemes is realized indeed. Analysis of the resonance enhancement mechanism of neutrino oscillations in matter is performed. It is shown that there are no indications on existence of this effect. It is shown that the supposition that the neutrinos are Majorana particles is not confirmed by accelerator experiments. Then only mixings (oscillations) between Dirac neutrinos with different flavors without sterile neutrinos can be realized. Using all the present experimental data and the theoretical results the problem of Sun neutrinos deficit is analyzed. The conclusion is: the primary Sun $ν_e$ neutrinos are converted into mixtures of three types of neutrinos $ν_e, ν_μ, ν_τ$ in approximately equal quantities.

description: Optical frequency comb-referenced measurements of self pressure-broadened line profiles of the R(8) to R(13) lines in the \thisband combination band of acetylene near 1.52$μ$m are reported. The analysis of the data found no evidence for a previously reported [Iwakuni et al. \textit{Phys. Rev. Letts.} \textbf{117}, 143902(5) 2016] systematic alternation in self pressure-broadened line widths with the nuclear spin state of the molecule. The present work brought out the need for the use of an accurate line profile model and a careful accounting for weak background absorptions due to hot-band and lower abundance isotopomer lines. The data were adequately fit using the quadratic speed-dependent Voigt profile model, neglecting the small speed-dependent shift. Parameters describing the most probable and speed-dependent pressure-broadening, most probable shift, and the line strength were determined for each line. Detailed modeling of the results of Iwakuni et al. showed that their neglect of collisional narrowing due to the speed-dependent broadening term, combined with the strongly absorbing data recorded and analyzed in transmission mode were likely the reasons for their results.

description: The dynamic variation of net primary productivity of artificial Pinus tabulaeformis forest was studied in Shanxi Province, and potential productivity of artificial forest was predicted to provide reference for improving quality of regional forest stand. The regression equation was established by using the stratification and harvesting method with the relative growth model. Cumulative method and Thornthwaite Memorial model was used to estimate the actual and potential productivity of the forest. The productivity of P. tabulaeformis forest increased with the increase of age and started decrease with the mature period. The actual productivity of P. tabulaeformis forest was 4.462 t/(ha•a); the contribution rate of trees was 72.17% of the total productivity, and with the increase of age, the total biomass increased but productivity decreased at late near-mature forest; the contribution rate of herb layer was 21.16% in the young forest stage, and then decreased gradually. On the contrary, the contribution rate of shrub layer increased gradually, and the contribution rate of the grassland was more than that of the herb layer, so as the key period of structural management; the average potential productivity of forest was 8.422 t/(ha•a), and the potential space of P. tabulaeformis was at least 32% in Shanxi Province. In conclusion, the potential space of productivity of P. tabulaeformis was at least 32%, and the primary limiting factor of P. tabulaeformis forest productivity in Shanxi Province was rainfall.

description: We present an XMM observation of the radio jet and diffuse halo of the nearby radio galaxy NGC6251. The EPIC spectrum of the galaxy's halo is best-fitted by a thermal model with temperature kT~1.6 keV and subsolar abundances. Interestingly, an additional hard X-ray component is required to fit the EPIC spectra of the halo above 3 keV, and is independently confirmed by an archival Chandra observation. However, its physical origin is not clear. Contribution from a population of undetected Low Mass X-ray Binaries seems unlikely. Instead, the hard X-ray component could be due to inverse Compton scattering of the CMB photons off relativistic electrons scattered throughout the halo of the galaxy, or non-thermal bremsstrahlung emission. The IC/CMB interpretation, together with limits on the diffuse radio emission, implies a very weak magnetic field, while a non-thermal bremsstrahlung origin implies the presence of a large number of very energetic electrons. We also detect X-ray emission from the outer (~3.5') jet, confirming previous ROSAT findings. Both the EPIC and ACIS spectra of the jet are best-fitted by a power law with photon index \~1.2. A thermal model is formally ruled out by the data. Assuming an origin of the X-rays from the jet via IC/CMB, as suggested by energetic arguments, and assuming equipartition implies a large Doppler factor (delta~10). Alternatively, weaker beaming is possible for magnetic fields several orders of magnitude lower than the equipartition field.

description: Since the 18th National Congress of the Communist Party of China (CPC), with the help of state policies, the new types of agricultural businesses have been flourishing. As one of the important forces of new types of agricultural businesses, the farmer's specialized cooperatives grow up rapidly in the development of the rural economy because of their characteristics which are consistent with the current rural economy. financial management is the core of the operation of farmer cooperatives, which directly affects the long-term sustainable development of cooperatives. Through the survey and analysis of the financial management of many farmers' cooperatives in Wei County, Hebei Province, this paper puts forward the deficiencies in the existing financial management of cooperatives. It also brings some reasonable suggestions to regulate and improve the financial management of cooperatives, in order to enhance the market competitiveness of farmers' cooperatives and realize better sustainable development of farmers' cooperatives.

description: The improvement of urbanization level in China and long-term development of economy in vast rural areas commonly impel rapid development of urbanization in China by “stronghold type” of small town and “radiation type” of big town. Urbanization roadwith Chinesecharacteristics impels urbanization and industrialization development, which needs relying on the development of small town. Due to the impact of town, space environment of “village in town” changes, and rural memory weakens.The state of “non city and non township” deeply affects rural development. Meanwhile, due to limited by urban-rural dualism, top-down planning of “village in town” is obviously unworkable. In this paper, analysis and interpretation on the problems of “village in town” are conducted, the cause is found, and effective channel of solving problem is obtained.

description: We present a detailed study of the Halpha and He I spectral features of COM J1740-5340 (the companion to PSR J1740-5340 in the Galactic Globular Cluster NGC 6397), exploiting a series of high resolution spectra obtained at different orbital phases. The Halpha absorption line shows a complex two-component structure, revealing that optically thin hydrogen gas resides outside the Roche lobe of COM J1740-5340. The line morphology precludes the existence of any residual disk around the millisecond pulsar, and suggests the presence of a stream of material going from the companion toward the neutron star. This material never reaches the neutron star surface, being driven back by the pulsar radiation far beyond COM J1740-5340. By analyzing the He I absorption lines as a function of orbital phase, we infer the presence of an overheated longitudinal strip (about 150 times narrower than it is long) on the COM J1740-5340 surface facing the radio pulsar.

description: Ensembles of neural networks have been shown to give better performance than single networks, both in terms of predictions and uncertainty estimation. Additionally, ensembles allow the uncertainty to be decomposed into aleatoric (data) and epistemic (model) components, giving a more complete picture of the predictive uncertainty. Ensemble distillation is the process of compressing an ensemble into a single model, often resulting in a leaner model that still outperforms the individual ensemble members. Unfortunately, standard distillation erases the natural uncertainty decomposition of the ensemble. We present a general framework for distilling both regression and classification ensembles in a way that preserves the decomposition. We demonstrate the desired behaviour of our framework and show that its predictive performance is on par with standard distillation.

description: We compute the primordial scalar, vector and tensor metric perturbations arising from quantum field inflation. Quantum field inflation takes into account the nonperturbative quantum dynamics of the inflaton consistently coupled to the dynamics of the (classical) cosmological metric. For chaotic inflation, the quantum treatment avoids the unnatural requirements of an initial state with all the energy in the zero mode. For new inflation it allows a consistent treatment of the explosive particle production due to spinodal instabilities. Quantum field inflation (under conditions that are the quantum analog of slow roll) leads, upon evolution, to the formation of a condensate starting a regime of effective classical inflation. We compute the primordial perturbations taking the dominant quantum effects into account. The results for the scalar, vector and tensor primordial perturbations are expressed in terms of the classical inflation results. For a N-component field in a O(N) symmetric model, adiabatic fluctuations dominate while isocurvature or entropy fluctuations are negligible. The results agree with the current WMAP observations and predict corrections to the power spectrum in classical inflation.Such corrections are estimated to be of the order of m^2/[N H^2] where m is the inflaton mass and H the Hubble constant at horizon crossing. This turns to be about 4% for the cosmologically relevant scales. This quantum field treatment of inflation provides the foundations to the classical inflation and permits to compute quantum corrections to it.

description: There are few studies on the treatment orientation of psychological counseling and psychotherapy practitioners in China. Additionally, integrative therapy as the first choice is much commoner in less developed areas and among unsupervised practitioners, which reflects the risk of technical confusion relating to the use of integrative therapy in China. The counseling and psychotherapy practitioners are treated as "variables", and researchers are concerned because these "variables" can have a significant impact on the course of treatment and outcomes. Therefore, we analyze the effects of socioeconomic development level on practitioners' treatment orientation. Based on the results, in addition to areas of employment, urban stratification and practitioners’ system factors, gender, age, education, professional background, work hours, and other factors affect psychological counseling and psychological treatment practitioners.

description: In recent years, under the stimulation of the national policy and the land circulation policy, the villages and towns have begun to guide the farmers to carry on the land circulation in an orderly way, combine the targeted poverty alleviation with the development of modern agriculture, and drive the registered households to participate in the modern agricultural industry and achieve the goal of getting rid of poverty and getting rich while realizing the transformation and upgrading of agriculture. The transfer of land management right can drive the local employment and the poverty reduction through industrial development is implemented. Taking Mopi Village in Xinping County as an example, this paper analyzes the main methods and effects of the transfer of land management right in this village in promoting poverty reduction through industrial development, and puts forward the existing problems and suggestions.
The spatial clustering of radio sources in NVSS and FIRST; implications for galaxy clustering evolution

description: We have measured the angular correlation function of radio sources in the 1.4 GHz NVSS and FIRST surveys. Below ~6 arcminutes w(theta) is dominated by the size distribution of radio galaxies. A model of the size distribution of radio galaxies can account for this excess signal in w(theta). The amplitude of the cosmological clustering of radio sources is roughly constant at A~0.001 from 3 to 40 mJy, but has increased to A~0.007 at 200 mJy. This can be explained if powerful (FRII) radio galaxies probe more massive structures at z~1 compared to average power radio galaxies, consistent with powerful high-z radio galaxies generally having massive (forming) elliptical hosts in rich cluster environments. For FRIIs we derive a spatial (comoving) correlation length of r_0=14\pm3 h^{-1} Mpc. This is close to that measured for extremely red objects (EROs) associated with a population of old elliptical galaxies at z~1 by Daddi et al. (2001). Based on their similar clustering properties, we propose that EROs and powerful radio galaxies may be the same systems seen at different evolutionary stages. Their r_0 is ~2 times higher than that of QSOs at a similar redshift, and comparable to that of bright ellipticals locally. This suggests that r_0 (comoving) of these galaxies has changed little from z~1 to z=0, in agreement with current LCDM hierarchical models for clustering evolution of massive early-type galaxies. Alternatively, the clustering of radio galaxies can be explained by the galaxy conservation model. This then implies that radio galaxies of average power are the progenitors of the local early-type field population, while the most powerful radio galaxies will evolve into a present-day population with r_0 similar to that of local rich clusters.

description: Statistics on U.S. agricultural exports to Eastern Europe frequently understate the volume of actual U.S. exports to the region. Due to the large volume of U.S. agricultural exports to Eastern Europe that are transshipped through Canada and Western Europe, there is ample opportunity for the final destinations of these commodities to be obscured. There are several sources of U.S. agricultural export data but because of the transshipments problem each is deficient.

description: We measure cosmological parameters using the three-dimensional power spectrum P(k) from over 200,000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with WMAP and other data. Our results are consistent with a ``vanilla'' flat adiabatic Lambda-CDM model without tilt (n=1), running tilt, tensor modes or massive neutrinos. Adding SDSS information more than halves the WMAP-only error bars on some parameters, tightening 1 sigma constraints on the Hubble parameter from h~0.74+0.18-0.07 to h~0.70+0.04-0.03, on the matter density from Omega_m~0.25+/-0.10 to Omega_m~0.30+/-0.04 (1 sigma) and on neutrino masses from <11 eV to <0.6 eV (95%). SDSS helps even more when dropping prior assumptions about curvature, neutrinos, tensor modes and the equation of state. Our results are in substantial agreement with the joint analysis of WMAP and the 2dF Galaxy Redshift Survey, which is an impressive consistency check with independent redshift survey data and analysis techniques. In this paper, we place particular emphasis on clarifying the physical origin of the constraints, i.e., what we do and do not know when using different data sets and prior assumptions. For instance, dropping the assumption that space is perfectly flat, the WMAP-only constraint on the measured age of the Universe tightens from t0~16.3+2.3-1.8 Gyr to t0~14.1+1.0-0.9 Gyr by adding SDSS and SN Ia data. Including tensors, running tilt, neutrino mass and equation of state in the list of free parameters, many constraints are still quite weak, but future cosmological measurements from SDSS and other sources should allow these to be substantially tightened.

description: Citation distributions are lognormal. We use 30 lognormally distributed synthetic series of numbers that simulate real series of citations to investigate the consistency of the h index. Using the lognormal cumulative distribution function, the equation that defines the h index can be formulated; this equation shows that h has a complex dependence on the number of papers (N). We also investigate the correlation between h and the number of papers exceeding various citation thresholds, from 5 to 500 citations. The best correlation is for the 100 threshold but numerous data points deviate from the general trend. The size-independent indicator h/N shows no correlation with the probability of publishing a paper exceeding any of the citation thresholds. In contrast with the h index, the total number of citations shows a high correlation with the number of papers exceeding the thresholds of 10 and 50 citations; the mean number of citations correlates with the probability of publishing a paper that exceeds any level of citations. Thus, in synthetic series, the number of citations and the mean number of citations are much better indicators of research performance than h and h/N. We discuss that in real citation distributions there are other difficulties.

description: Logit regression analyses of 1978 Resource Economic Survey data are performed to determine factors distinguishing farmland owners who invested in soil con— servation practices from owners who did not invest. In most areas studied, owners who operated their land or who used share leases on land rented out were more likely to have invested than owners who rented out all land using only cash leases. The need for policies to encourage greater investment is suggested by evidence of trends toward increase in the percentage of all farmland that is owned by nonoperators and in the percentage of rental land that is farmed under cash leases.

The technique of the research includes i) an analysis of well-known literature SAXS data; on this base, at some assumptions, ii) constructing a simple model to estimate geometric structure parameters and to receive a simulated scattering curve, iii) calculations of energetic parameters by help of the analytical fluctuation theory of the phase transitions; iv) comparing the model with the real structure obtained from the SAXS data by the electron density distribution reconstruction method. In the presence of an effective field the 2-nd order phase transition transforms to the 1-st order one in the vicinity of the Lifshitz point. As a result, a bicontinuous structure in cubic mesophases is formed.

description: Drift Consulting has been engaged by UBC Social Ecological Economic Development Studies (SEEDS) to develop a design for a multi-purpose detention facility which will address the stormwater management issues in the proximity of the UBC Centre for Comparative Medicine (CCM). The design provides 3000 m³ of water storage in a trench system alongside new and existing trails in the South Campus Region. The same trench system controls the outflow of flood water into the outfall at Booming Grounds Creek. The flow is controlled by a series of 30 dams positioned at 50 m intervals along the trenches. Furthermore, the retention time and flow velocity of trench system ensures that the water exiting the system has achieved primary water treatment standards. The trench and trail system are integrated seamlessly with the surrounding environment, as well as the built infrastructure. The new trail connects two existing trials, providing a continuous connection from the Spirit Park trail network to the Botanical Garden regional trails. This report covers a general overview of the project, the relevant regulations and standards, a detailed description of design components and detailed method for construction. A construction schedule and cost estimate are provided in addition to the design components which consists of drawings, calculations and dimensions.

description: A mixed integer programming model is used to simulate wastewater treatment costs with seasonal variations in water quality standards for a representative stream basin. Water quality constraints are determined for two seasons (winter and summer) using a stream model. Annual cost savings range from $1,000 to $117,000 depending upon the constraints imposed. If a minimum of secondary wastewater treatment is required at all times the annual cost savings are $14,000. Relaxation of the secondary treatment requirements increases the annual cost savings to $35,000. If phosphorus removal is required during the summer but not during the winter months, the largest cost savings occur.

description: Chemical reactions occur in energy, environmental, biological, and many other natural systems, and the inference of the reaction networks is essential to understand and design the chemical processes in engineering and life sciences. Yet, revealing the reaction pathways for complex systems and processes is still challenging due to the lack of knowledge of the involved species and reactions. Here, we present a neural network approach that autonomously discovers reaction pathways from the time-resolved species concentration data. The proposed Chemical Reaction Neural Network (CRNN), by design, satisfies the fundamental physics laws, including the Law of Mass Action and the Arrhenius Law. Consequently, the CRNN is physically interpretable such that the reaction pathways can be interpreted, and the kinetic parameters can be quantified simultaneously from the weights of the neural network. The inference of the chemical pathways is accomplished by training the CRNN with species concentration data via stochastic gradient descent. We demonstrate the successful implementations and the robustness of the approach in elucidating the chemical reaction pathways of several chemical engineering and biochemical systems. The autonomous inference by the CRNN approach precludes the need for expert knowledge in proposing candidate networks and addresses the curse of dimensionality in complex systems. The physical interpretability also makes the CRNN capable of not only fitting the data for a given system but also developing knowledge of unknown pathways that could be generalized to similar chemical systems.

Radio spectra of a sample of X-ray selected BL Lacs

description: We present simultaneous multifrequency radio observations for a complete subsample of 26 XBLs from the Einstein Extended Medium-Sensitivity Survey, obtained with the Very Large Array (VLA). Spectra are computed using fluxes at 20, 6 and 3.6 cm. Unlike many radio selected samples, the EMSS did not impose any criterion on the radio spectrum to identify BL Lac objects. It is therefore possible to investigate the intrinsic radio spectral slope distribution and to determine the effect produced by this selection criterion. We find that 15% of the observed objects do not meet the flat-spectrum criterion imposed on some other BL Lac samples. A dataset that includes non-simultaneous data (that are also taken with different VLA configurations) shows an even higher percentage of steep spectrum sources. This effect can be ascribed to a larger fraction of extended flux detected with the more compact VLA configuration.Possible biases introduced by the flat--radio-spectrum criterion in the radio-selected BL Lac samples cannot explain the discrepancies observed in the evolutionary properties of Radio and X-ray selected samples of BL Lacs.

Inference for Batched Bandits

description: As bandit algorithms are increasingly utilized in scientific studies and industrial applications, there is an associated increasing need for reliable inference methods based on the resulting adaptively-collected data. In this work, we develop methods for inference on data collected in batches using a bandit algorithm. We first prove that the ordinary least squares estimator (OLS), which is asymptotically normal on independently sampled data, is not asymptotically normal on data collected using standard bandit algorithms when there is no unique optimal arm. This asymptotic non-normality result implies that the naive assumption that the OLS estimator is approximately normal can lead to Type-1 error inflation and confidence intervals with below-nominal coverage probabilities. Second, we introduce the Batched OLS estimator (BOLS) that we prove is (1) asymptotically normal on data collected from both multi-arm and contextual bandits and (2) robust to non-stationarity in the baseline reward.

description: We have obtained a Halpha position-velocity cube from Fabry-Perot interferometric observations of the HH 110 flow. We analyze the results in terms of anisotropic wavelet transforms, from which we derive the spatial distribution of the knots as well as their characteristic sizes (along and across the outflow axis). We then study the spatial behaviour of the line width and the central radial velocity. The results are interpreted in terms of a simple ``mean flow+turbulent eddy'' jet/wake model. We find that most of the observed kinematics appear to be a direct result of the mean flow, on which are superposed low amplitude (35 km/s) turbulent velocities.

description: We study the minimally supported representations of quantizations of Gieseker moduli spaces. We relate them to $\operatorname{SL}_n$-equivariant D-modules on the nilpotent cone of $\mathfrak{sl}_n$ and to minimally supported representations of type A rational Cherednik algebras. Our main result is character formulas for minimally supported representations of quantized Gieseker moduli spaces.

description: Siksin Consultants Ltd. has been tasked with developing a mixed solution of a car parkade and stormwater management system project to mitigate extreme flooding that may occur in a 1 in a 100-year storm event around the area of Marine Drive and West 16th Avenue, Vancouver. The goal of the design also includes creating a neighborhood welcoming atmosphere recreational area for the future neighborhood development. On the surface, the parkade, bioswales, skate board park and amphitheater act as a part of the stormwater collecting system. In an extreme storm event, the skate park and amphitheater are intended to hold and temporary store stormwater to help slow down rainfall runoff and prevent erosion at the cliff. Under normal weather circumstances, precipitation is collected from the car parkade to the bioswales along the current slopes down to the field. The bioswales serve to control the runoff flow rate and act as a natural filtration system. The collected water then travels through underdrain beneath the bioswales and is stored in the underground retention pipe system. An UV filtration system is also installed for water purification purposes. Once the storage tanks have reached its capacity, additional water is left at the various collection points for natural infiltration and evapotranspiration or transported directly to the sea through existing pipes. The existing car parkade is also revamped. A solar panel roof is added to provide renewable energy to the stormwater management system, in particular, supply energy to the pump. The current concrete ground is replaced by permeable porous asphalt to help infiltrate stormwater and additional storm drains will be placed for extra drainage. The car parkade capacity is reduced to 80 spots to encourage the use of alternative sustainable transportation methods.

description: The dynamics of a mobile hole in two-dimensional frustrated quantum magnets is investigated by exact diagonalization techniques. Our results provide evidence for spin-charge separation upon doping the kagome lattice, a prototype of a spin liquid. In contrast, in the checkerboard lattice, a symmetry broken Valence Bond Crystal, a small quasi-particle peak is seen for some crystal momenta, a finding interpreted as a restoration of weak holon-spinon confinement.

description: In this paper we present a method to analyse absorption line spectra of a galaxy designed to determine the stellar dynamics and the stellar populations by a direct fit to the spectra. This paper is the first one to report on the application of the method to data. The modelling results in the knowledge of distribution functions that are sums of basis functions. The practical implementation of the method is discussed and a new type of basis functions is introduced. With this method, a dynamical model for NGC 3258 is constructed. This galaxy can be successfully modelled with a potential containing 30% dark matter within 1r_e with a mass of 1.6x10^11 M_o. The total mass within 2r_e is estimated as 5x10^11 M_o, containing 63% dark matter. The model is isotropic in the centre, is radially anisotropic between 0.2 and 2 kpc (0.88 r_e) and becomes tangentially anisotropic further on. The photometry reveals the presence of a dust disk near the centre.
