description: We report spatial distributions of the Fe-K$α$ line at 6.4 keV and the CO($J$ = 2--1) line at 230.538 GHz in NGC 2110, which are respectively revealed by $Chandra$ and ALMA at $\approx$ 0.5 arcsec. A $Chandra$ 6.2--6.5 keV-to-3.0--6.0 keV image suggests that the Fe-K$α$ emission extends preferentially in a northwest-to-southeast direction out to $\sim$ 3 arcsec, or 500 pc, on each side. Spatially-resolved spectral analyses support this by finding significant Fe-K$α$ emission lines only in northwest and southeast regions. Moreover, their equivalent widths are found $\sim$ 1.5 keV, indicative for the fluorescence by nuclear X-ray irradiation as the physical origin. By contrast, CO($J$ = 2--1) emission is weak therein. For quantitative discussion, we derive ionization parameters by following an X-ray dominated region (XDR) model. We then find them high enough to interpret the weakness as the result of X-ray dissociation of CO and/or H$_2$. Another possibility also remains that CO molecules follow a super-thermal distribution, resulting in brighter emission in higher-$J$ lines. Further follow-up observations are encouraged to draw a conclusion on what predominantly changes the inter-stellar matter properties, and whether the X-ray irradiation eventually affects the surrounding star formation as an AGN feedback.

description: We study optical cycling in the polar free radical calcium monohydroxide (CaOH) and establish an experimental path towards scattering $\sim$$10^4$ photons. We report rovibronic branching ratio measurements with precision at the $\sim10^{-4}$ level and observe weak symmetry-forbidden decays to bending modes with non-zero vibrational angular momentum. Calculations are in excellent agreement with these measurements and predict additional decay pathways. Additionally, we perform high-resolution spectroscopy of the $\widetilde{\text{X}}\,^2Σ^+(12^00)$ and $\widetilde{\text{X}}\,^2Σ^+(12^20)$ hybrid vibrational states of CaOH. These advances establish a path towards radiative slowing, 3D magneto-optical trapping, and sub-Doppler cooling of CaOH.

description: The deviation of the electron density around the nuclei from spherical symmetry determines the electric field gradient (EFG), which can be measured by various types of spectroscopy. Nuclear Quadrupole Resonance (NQR) is particularly sensitive to the EFG. The EFGs, and by implication NQR frequencies, vary dramatically across materials. Consequently, searching for NQR spectral lines in previously uninvestigated materials represents a major challenge. Calculated EFGs can significantly aid at the search inception. To facilitate this task, we have applied high-throughput density functional theory calculations to predict EFGs for 15187 materials in the JARVIS-DFT database. This database, which will include EFG as a standard entry, is continuously increasing. Given the large scope of the database, it is impractical to verify each calculation. However, we assess accuracy by singling out cases for which reliable experimental information is readily available and compare them to the calculations. We further present a statistical analysis of the results. The database and tools associated with our work are made publicly available by JARVIS-DFT ( https://www.ctcms.nist.gov/~knc6/JVASP.html ) and NIST-JARVIS API ( http://jarvis.nist.gov ).

description: In this work we investigate the effects of the Gribov prescription to get rid of zero-modes of the Faddeev-Popov operator, at one-loop order in perturbation theory, in the Landau-DeWitt gauge. Quantum fluctuations are taken around a transverse background gauge field. The one-loop effective action is explicitly computed, and the behavior of the gauge and ghost fields propagators are carefully investigated. At one-loop and for generic transverse background configurations the effective action is found to be \textit{not} background invariant, as expected, due to a non-vanishing background contribution. The gauge field propagator has the same form as in the case {where the} background is a trivial field, $i.e.$ with complex conjugate poles, which are modified by the corresponding gap equation. The ghost-anti-ghost propagator still displays its enhanced $\sim p^{-4}$ behavior.

description: Previously, it has been know that Glucose + 6O2 + …..→ 6H2O + 6CO2 +…….+ energy Now, we can use of reverse state and produce oxygen. During respiration, some carbon dioxide molecules go out from the body. We can take them and by using a huge pressure, inject them into a water system. We can write: 6H2O + 6CO2 +…….+ energy→Glucose + 6O2 + …. Needed energy could be produced by a pressure which is emerged during respiration within vessels of mask. To accelerate interactions, we need to add some useful matters. Microbes are confined within the bubbles and because of their masses go below the mask and out of system, while, gases go up and towards the face.

description: Groundwater offers us few but precious opportunities for alleviating the misery of the poor; but it poses many—and daunting—challenges of preserving the resource itself. A big part of the answer is massive initiatives to augment groundwater recharge in regions suffering depletion; but, in the ultimate analysis, these cannot work without appropriate demand-side interventions. The water vision of a world that future generations will inherit will have to be the one in which groundwater plays its full developmental, productive and environmental role but in a sustainable manner; and the framework of action to realize this vision will mean eschewing the current free-for-all in groundwater appropriation and use, and promoting a more responsible management of this precious resource that is easy to deplete or ruin—through depletion, salinization and pollution

description: A nanodevice consisting of a conductive cylinder in an axial magnetic field with one-dimensional wires attached to its lateral surface is considered. An explicit form for transmission and reflection coefficients of the system as a function of electron energy is found from the first principles. The form and the position of transmission resonances and zeros are studied. It is found that, in the case of one wire being attached to the cylinder, reflection peaks occur at energies coinciding with the discrete part of the electronic spectrum of the cylinder. These peaks are split in a magnetic field. In the case of two wires the asymmetric Fano-type resonances are detected in the transmission between the wires for integer and half-integer values of the magnetic flux. The collapse of the resonances appears for certain position of contacts. Magnetic field splits transmission peaks and leads to spin polarization of transmitted electrons.

Virus

description: Spinor mask could be built from spinors like some non-harmful ions, triplet oxygen molecules and polarized water molecules. This Mask could repel any virus in three stages: Stage 1: A virus is built from atoms and electrons which have spins. Thus, its surface could have different spins in each time. When a virus become closed to a spinor mask, parallel spins go away and anti-parallel spins become closed. Stage 2: Anti-parallel spins and polarized water molecules move around viruses and build some bubbles which could fly and escape from the system. Stage 3:By passing time, spins of spinors on the surface of virus may change and consequently, parallel spins of bubble become closed to spins of virus and destroy its structure.
Glaciovolcanism at the Mount Cayley volcanic field, Garibaldi volcanic belt, Southwestern British Columbia
Creators: name: Kelman, Melanie Catherine
Publisher: name: University of British Columbia
Year: 2009

description: This thesis investigates glaciovolcanism in the Mount Cayley volcanic field (MCVF) of southwestern British Columbia's Garibaldi Volcanic Belt (GVB). The MCVF is dominated by intermediate magma compositions, has been intermittently glaciated, and has extreme topography. No study to date has focused on intermediate composition glaciovolcanic deposits in a similar setting. The core of this thesis is a 1:20,000 volcanological map, which was used in conjunction with field observations, geochemical data, and petrographic examinations to investigate the volcanological history of the MCVF, to investigate the eruptive processes that produce specific glaciovolcanic landforms, and to make predictions about paleo-ice thicknesses and distributions. The MCVF (and the entire GVB) has three dominant intermediate composition glaciovolcanic landform types: subglacial domes, flow-dominated tuyas, and impoundment features. Subglacial domes are irregularly-shaped piles of lava flows representing subglacial eruptions that commenced beneath 100-650 m of ice and did not breach the surface; in many cases, the subglacial domes grew to within 150 m of the ice surface. Flow-dominated tuyas are steep-sided, flat-topped stacks of lava flows representing subglacial eruptions that ultimately breached the ice surface. Subglacial domes and flow-dominated tuyas represent the same eruptive process, the primary difference being whether or not the ice was breached. Impoundment features are subaerial lava flows with steep flanks or termini representing channeling or ponding of lava by ice. All three landforms have intense fine-scale jointing that indicates cooling surfaces inconsistent with apparent paleotopography. Additionally, all lack features recording eruption into water (pillows and hyaloclastite), indicating efficient and continuous meltwater drainage during eruptions. This is different from glaciovolcanic deposits in most other settings. It also makes these deposits distinct from basaltic glaciovolcanic deposits in the GVB. A combination of ice geometry, topography, and magma composition is responsible; thin ice promotes the formation of drainage pathways around subglacial vents, while thin ice coupled with steep bedrock topography creates hydraulic gradients away from vents. Magma composition probably also plays a role, due to its effect on quantities of ice melted and the pressure in subglacial vent cavities and drainage conduits.

description: Supermarkets are gaining ground in the agri-food systems of many developing countries. While recent research has analyzed income effects in the small farm sector, impacts on productivity and efficiency have hardly been studied. We use a meta-frontier approach and combine this with propensity score matching to estimate treatment effects among vegetable farmers in Kenya. Participation in supermarket channels increases farm productivity in terms of meta-technology ratios by 45%. We also find positive and significant impacts on technical efficiency and scale efficiency. Supermarket expansion therefore presents opportunities for agricultural growth in the small farm sector, which is crucial for poverty reduction in Africa.
A Detailed Examination of Anisotropy and Timescales in Three-dimensional Incompressible Magnetohydrodynamic Turbulence

subject: FOS: Physical sciences

description: When magnetohydrodynamic turbulence evolves in the presence of a large-scale mean magnetic field, an anisotropy develops relative to that preferred direction. The well-known tendency is to develop stronger gradients perpendicular to the magnetic field, relative to the direction along the field. This anisotropy of the spectrum is deeply connected with anisotropy of estimated timescales for dynamical processes, and requires reconsideration of basic issues such as scale locality and spectral transfer. Here analysis of high-resolution three-dimensional simulations of unforced magnetohydrodynamic turbulence permits quantitative assessment of the behavior of theoretically relevant timescales in Fourier wavevector space. We discuss the distribution of nonlinear times, Alfvén times, and estimated spectral transfer rates. Attention is called to the potential significance of special regions of the spectrum, such as the two-dimensional limit and the "critical balance" region. A formulation of estimated spectral transfer in terms of a suppression factor supports a conclusion that the quasi two-dimensional fluctuations (characterized by strong nonlinearities) are not a singular limit, but may be in general expected to make important contributions.

description: An optimization of the CERN SPL beam line has been performed guided by the sensitivities to the θ_{13} mixing angle and to the δ_{CP} Dirac CP violating phase. A UNO-like 440 ktons water Cerenkov detector located at 130 km from the target in a new foreseen Frejus laboratory has been used as a generic detector. Concerning the δ_{CP} independent θ_{13} sensitivity, a gain of about 20% may be reached using a 3.5 GeV proton beam with a 40 m long, 2 m radius decay tunnel compared to the up to now considered 2.2 GeV beam energy and 20 m long, 1 m radius decay tunnel. This may motivate new machine developments to upgrade the nominal SPL proton beam energy.

description: The aim of sparse phase retrieval is to recover a $k$-sparse signal $\mathbf{x}_0\in \mathbb{C}^{d}$ from quadratic measurements $|\langle \mathbf{a}_i,\mathbf{x}_0\rangle|^2$ where $\mathbf{a}_i\in \mathbb{C}^d, i=1,\ldots,m$. Noting $|\langle \mathbf{a}_i,\mathbf{x}_0\rangle|^2={\text{Tr}}(A_iX_0)$ with $A_i=\mathbf{a}_i\mathbf{a}_i^*\in \mathbb{C}^{d\times d}, X_0=\mathbf{x}_0\mathbf{x}_0^*\in \mathbb{C}^{d\times d}$, one can recast sparse phase retrieval as a problem of recovering a rank-one sparse matrix from linear measurements. Yin and Xin introduced PhaseLiftOff which presents a proxy of rank-one condition via the difference of trace and Frobenius norm. By adding sparsity penalty to PhaseLiftOff, in this paper, we present a novel model to recover sparse signals from quadratic measurements. Theoretical analysis shows that the solution to our model provides the stable recovery of $\mathbf{x}_0$ under almost optimal sampling complexity $m=O(k\log(d/k))$. The computation of our model is carried out by the difference of convex function algorithm (DCA). Numerical experiments demonstrate that our algorithm outperforms other state-of-the-art algorithms used for solving sparse phase retrieval.

description: We report a discovery of strong modulations of the X-ray flux detected from IGR J16320-4751 = AX J1631.9-4752 with a period of P~1300 sec. We reanalyzed the data of an XMM-Newton ToO performed soon after the discovery of the source by INTEGRAL and found the modulation at a period of P=1309+/-40 sec with a high significance. Modulations of the source flux with two possible periods of ~1300 and ~1500 sec were identified in the ASCA archival data. It is very likely that the modulation can be interpreted as X-ray pulsations, favouring a pulsar as the compact object in IGR/AX J16320-4752. Thus for the moment this source became the fourth source from a new class of highly absorbed binary systems for which the pulsations are observed.

description: Literatures about agricultural production efficiency are reviewed. Concept of DEA Method, as well as the definition methods of effective DEA and scale efficiency increase is introduced. According to the relevant statistical data in the years 1997-2007 in Chongqing Municipality, efficiency of agricultural economy is calculated from the year 1997 to 2007 by DEA method and the scale efficiency is also analyzed by taking the total output of agriculture, forestry, animal husbandry and fishery industry as the output index. And the input index includes total workforce in agriculture, forestry, animal husbandry and fishery, the total sown area of crops, the total power of agricultural machinery, chemical fertilizer application, the draft animal, and the effective irrigation area. Result shows that Chongqing City became a municipality directly under the central government; its agricultural production efficiency is still low. And the sustainable development capacity of agricultural is weak in Chongqing, and the agricultural resources are not fully used. Based on this, related suggestions are put forward to improve the agricultural production efficiency of Chongqing, such as implementing an appropriate management scale of land, improving the organization degree of peasant households and the rate of industrialization management, enhancing the quality of the rural labor force, strengthening the agricultural science and technology input and extension, perfecting the construction of rural infrastructure, and improving the rate of resource utilization.

description: Observations of magnetic fields on scales up to several Mpc are important for understanding cluster and large-scale structure evolution. Our current census of such structures is heavily biased -- towards fields of several microG, towards fields in deep potential wells, and towards high inferred field strengths in cooling flow and other clusters from improper analysis of rotation measure data. After reviewing these biases, I show some recent results on two relics that are powered in very different ways. I describe new investigations that are now uncovering weak diffuse fields in the outskirts of clusters and other low density environments, and the good prospects for further progress.

description: We consider the Schr\''odinger equation \begin{equation}\label{eq_abstract} i\partial_t u(t)=-Δu(t)~~~~~\text{ on }Ω(t) \tag{$\ast$} \end{equation}where $Ω(t)\subset\mathbb{R}$ is a moving domain depending on the time $t\in [0,T]$. The aim of this work is to provide a meaning to the solutions of such an equation. We use the existence of a bounded reference domain $Ω_0$ and a specific family of unitary maps $h^\sharp(t): L^2(Ω(t),\mathbb{C})\longrightarrow L^2(Ω_0,\mathbb{C})$. We show that the conjugation by $h^\sharp$ provides a newequation of the form \begin{equation}\label{eq_abstract2}i\partial_t v= h^\sharp(t)H(t)h_\sharp(t) v~~~~~\text{ on }Ω_0\tag{$\ast\ast$} \end{equation} where $h_\sharp=(h^\sharp)^{-1}$. The Hamiltonian $H(t)$ is a magnetic Laplacian operator of the form$$H(t)=-(div+iA)\circ(grad+iA)-|A|^2$$where $A$ is an explicit magnetic potential depending on the deformation of the domain $Ω(t)$. The formulation \eqref{eq_abstract2} enables to ensure the existence of weak and strong solutions of the initial problem \eqref{eq_abstract} on $Ω(t)$ endowed with Dirichlet boundary conditions. In addition, it also indicates that the correct Neumann type boundary conditions for \eqref{eq_abstract} are not the homogeneous but the magnetic ones$$\partial_νu(t)+i\langleν| A\rangle u(t)=0,$$even though \eqref{eq_abstract} has no magnetic term. All the previous results are also studied in presence of diffusion coefficients as well as magnetic and electric potentials. Finally, we prove some associated byproducts as an adiabatic result for slow deformations of the domain and atime-dependent version of the so-called ``Moser's trick''. We use this outcome in order to simplify Equation \eqref{eq_abstract2} and to guarantee the well-posedness for slightly less regular deformations of $Ω(t)$.

Then, Guilin is taken as an example, the problems existing in constructing the supply chain and brand of Guilin characteristic economic agricultural products are pointed out after the analysis of its current situations, the problems include weak agricultural production infrastructure, weak deep products processing capacity, low modernization level of storage and transportation as well as short of fixed marketing channels; meanwhile, brand construction faces the problems of little top brands and few differentiated products. Finally, some measures are proposed to solve these problems from the perspectives of establishing the management idea of agricultural products supply chain and enhancing the awareness to protect agricultural products brand, it is also suggested that these measures be extended to the whole Guangxi autonomous region in order to explore the way of the development of Guangxi characteristic agriculture.

description: This study puts forward a generalization of the short-time Fourier-based Synchrosqueezing Transform using a new local estimate of instantaneous frequency. Such a technique enables not only to achieve a highly concentrated time-frequency representation for a wide variety of AM-FM multicomponent signals but also to reconstruct their modes with a high accuracy. Numerical investigation on synthetic and gravitational-wave signals shows the efficiency of this new approach.

description: According to the cultivated area and grain yield during 1996- 2008 and adopting the prediction method of farmland demand based on food security, five indexes, including the cultivated area, grain sown area, yearly food yield per unit area, total population and per capita grain yield, are selected to analyze and predict the farmland demand in Yunnan Province in 2020. As the prediction results of each index show, the total population of Yunnan Province in 2020 will reach 51 464 000, significantly higher than the upper bound (50 million); the per capita food demand of Yunnan Province in 2020 will be 400kg below the bottom line of the well-off type; food self-sufficient ratio will be respectively given the value of 100%, 95% and 90% in three schemes; the prediction will be conducted with the yearly food yield per unit area at an average annual growth rate of 2.5% and 3.0% in two schemes; the rate of grain sowing in 2010 is determined to be 66%. As the prediction results of farmland demand show, there are totally 6 schemes about farmland demand in Yunnan Province obtained through analysis, among them, schemeⅠis difficult to achieve, the prediction results of scheme Ⅳ, Ⅴ and Ⅵ are relatively low, which do not conform to the state policies and regulations to protect farmland and are also not conductive for ensuring the food security; schemeⅡ and Ⅲ are close to each other, but scheme Ⅲ obtains better prediction results and determines the farmland demand of Yunnan province in 2020 based on food security to be 5.9 million so as to ensure the provincial food security and realize the “red line” of basic provincial food self-sufficiency.

Formation of unstable shocks for 2D isentropic compressible Euler
Creators: name: Buckmaster, Tristan
name: Iyer, Sameer
Publisher: name: arXiv
Year: 2020
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: In this paper we construct unstable shocks in the context of 2D isentropic compressible Euler in azimuthal symmetry. More specifically, we construct initial data that when viewed in self-similar coordinates, converges asymptotically to the unstable $C^{\frac15}$ self-similar solution to the Burgers' equation. Moreover, we show the behavior is stable in $C^8$ modulo a two dimensional linear subspace. Under the azimuthal symmetry assumption, one cannot impose additional symmetry assumptions in order to isolate the corresponding manifold of initial data leading to stability: rather, we rely on modulation variable techniques in conjunction with a Newton scheme.

description: The technical route of partial revision in overall plan of land utilization is briefly described. It is pointed out that the problem of area measuring in the technical route is mainly due to the digital process. The digital problems of partial revision in overall plan of land utilization are presented as follows: the maps are not being proofread before digitalization; the coordinate matching and projection transformation are not being conducted on the maps; the information is asymmetry before and after the digitalization; the location lacks precision; the result maps are substandard. The causes of these problems are analyzed, which cover the following aspects. The lack of united management regulations; the working ability of the staff in the compilation units is uneven; some staff can not aware the importance of the digitalization of maps; the basic condition of the former planning map is poor. At last, the relevant suggestions are put forward, for instance, releasing the national united management methods and technical criteria, establishing industry admission system and accreditation system of complication units, setting up the mechanism of supervising digitalized results and controlling the quality, conducting coordinate matching and projection transformation and unifying the specification and plate of the results of maps so as to provide technical support for the overall plan of land utilization, play the micro-regulating role of land utilization and take a leading role in the sustainable development of social economy.

description: Based on the overview of concept of returning-home migrant workers’ entrepreneurship, the thesis has introduced the features of migrant workers’ entrepreneurship, as against other types of entrepreneurship, as follows. Starting from a low base and multi-level perspective; conducting entrepreneurship in manifold industries, mainly in those labor-intensive enterprises; conspicuous mutual interaction and reversibility are embodied in the group characteristics; the strong driving force of returning-home migrant workers’ entrepreneurship comes from their affection for hometown. The process of returning-home migrant workers’ entrepreneurship can be divided into three stages, namely returning rush, investing rush, and entrepreneurship rush, on which we give the analysis respectively in terms of the continuous change of social mobility, transformation on the part of the main body of entrepreneurship, and the expansion of industry field concerning entrepreneurship. More over, we have discussed the methods of constructing the legal support system for the returning-home migrant workers’ entrepreneurship. Firstly, it needs institutionalization, which is the basis of constructing the legal support system for the returning-home migrant workers’ entrepreneurship; secondly, it needs definite guiding ideology as the premise of constructing the legal support system for the returning-home migrant workers’ entrepreneurship; thirdly, it needs the precise orientation of target group as the key of constructing the legal support system for the returning-home migrant workers’ entrepreneurship; finally, appropriate support methods are the pivot of constructing the legal support system for the returning-home migrant workers’ entrepreneurship.

description: We present a semi-analytic calculation on the atmospheric tau neutrino flux in the GeV to TeV energy range. The atmospheric $ν_τ$ flux is calculated for the entire zenith angle range. This flux is contributed by the oscillations of muon neutrinos coming from the two-body $π, K$ decays and the three-body $μ^{\pm}$ decays, and the intrinsic tau neutrino flux surviving the oscillations. The uncertainties in our calculations are discussed in detail. The implications of our result are also discussed.

Fermionic versus bosonic behavior of confined Wigner molecules

description: We assess whether a confined Wigner molecule constituted by $2N$ fermions behaves as $N$ bosons or $2N$ fermions. Following the work by C. K. Law [Phys. Rev. A \textbf{71}, 034306 (2005)] and Chudzicki et al. [Phys. Rev. Lett. \textbf{104}, 070402 (2010)] we discuss the physical meaning and the reason why a large amount of entanglement is needed in order to ensure a bosonic composite behavior. By applying a composite boson ansatz, we found that a Wigner molecule confined in two dimensional traps presents a bosonic behavior induced by symmetry. The two-particle Wigner molecule ground state required by the composite boson ansatz was obtained within the harmonic approximation in the strong interacting regime. Our approach allows us to address few-particle states (widely studied within a variety of theoretical and numerical techniques) as well as a large number of particles (difficult to address due to computational costs). For a large number of particles, we found strong fermionic correlations exposed by the suppression of particle fluctuations. For a small number of particles, we show that the wave function calculated within the composite boson ansatz captures the Friedel-Wigner transition. The latter is shown in a regime in which strong correlations due to the Pauli exclusion principle arise, therefore, we conclude that the coboson ansatz reproduces the many particle physics of a confined Wigner molecule, even in the presence of strong deviations of the ideal bosonic behavior due to fermionic correlations.
