description: We report on a new versatile transportable endstation for controlled molecule (eCOMO) experiments providing a combination of molecular beam purification by electrostatic deflection and simultaneous ion and electron detection using velocity-map imaging (VMI). The $b$-type electrostatic deflector provides spatial dispersion of species based on their effective-dipole-moment-to-mass ratio. This enables selective investigation of molecular rotational quantum states, conformers, and molecular clusters. Furthermore, the double-sided VMI spectrometer equipped with two high-temporal-resolution event-driven Timepix3 cameras provides detection of all generated ions independently of their mass-over-charge ratio and electrons. To demonstrate the potential of this novel apparatus, we present experimental results from our investigation of carbonyl sulfide (OCS) after ionization. Specifically, we provide the characterization of the molecular beam, electrostatic deflector, and electron- and ion-VMI spectrometer. The eCOMO endstation delivers a platform for ultrafast dynamics studies using a wide range of light sources from table-top lasers to free-electron-laser and synchrotron-radiation facilities. This makes it suitable for research activities spanning from atomic, molecular, and cluster physics, to energy science and chemistry, to structural biology.
The Afghan agricultural extension system : impact of the Soviet occupation and prospects for the future
Creators: name: Wesa, Tooryalai
Publisher: name: University of British Columbia
Year: 2009

description: The Soviet Union occupied her southern neighbor Afghanistan on Thursday, December 27, 1979. Soon after the occupation, significant impacts were felt on agriculture and other sectors of the economy. Agriculture was affected in many ways from the integrity of irrigation systems to the cultivation of opium poppies. Agricultural extension, as the main department within the Ministry of Agriculture, was severely affected in terms of programs, organization, personnel, budget, methods, relations with farmers, and transfer of improved technologies. This study was designed to assess the impacts of the occupation and identify recommendations for the future development of the system. A survey design was used. Sixty-two Afghans with detailed knowledge about the Soviet occupation and agriculture participated in the study. The survey included 34 mostly open-ended questions, covering three areas: demographic characteristics of respondents, impacts of the occupation, and prospects for the future of the Agricultural Extension System of Afghanistan. The majority of participants were highly educated and lived in North America after departing Afghanistan. The results also showed that during the occupation many participants were assigned to passive positions or lost their jobs. The occupation affected the attitudes of the farmers, reduced the cultivation of agricultural land, destroyed the infrastructure for delivering agricultural services, altered the types of crops grown and reduced the number of people working in agriculture. Millions of landmines remain a serious threat to those who return to farming. Recommendations are made for the Government, Ministry of Agriculture, Ministry of Higher and Vocational Education, Agricultural Extension System, Non-governmental Organizations (NGOs), and International Aid Agencies. Agricultural extension rehabilitation should be given high priority to meet the emerging challenges of increasing agricultural production by adopting modern technology, generating suitable marketing channels for surplus agricultural products, providing equal development and working opportunities for Afghan women, protecting natural resources, utilizing professional returnees, and replacing poppy cultivation with regular food crops. Perceptual and structural obstacles may militate against providing proper support for agricultural development in Afghanistan. The overall reconstruction and development of the Afghan Agricultural Extension System is a prerequisite for the future development of the Afghan agriculture sector. Establishing a stable Afghan government and support from the international coalition are essential to rebuilding this important sector of the economy.

description: We show how to convert between partially coherent superpositions of a single photon with the vacuum using linear optics and postselection based on homodyne measurements. We introduce a generalized quantum efficiency for such states and show that any conversion that decreases this quantity is possible. We also prove that our scheme is optimal by showing that no linear optical scheme with generalized conditional measurements, and with one single-rail qubit input can improve the generalized efficiency.

description: One-dimensional wires are known to be inherently unstable at finite temperature. Here, we show thatlong-range order of atomic Au double chains adsorbed on a Si(553) surface is not only stabilized byinteraction with the substrate, but spontaneous self-healing of structural defects is actually enforced by theadsorption of atomic species such as Au or H. This is true even for random adsorbate distribution.Combining atomistic models within density functional theory with low energy electron diffraction andhigh-resolution electron energy loss spectroscopy, we demonstrate that this apparently counterintuitivebehavior is mainly caused by adsorption-induced band filling of modified surface bands, i.e., by the strongelectronic correlation throughout the whole terrace. Although adsorption preferably occurs at the step edge,it enhances the dimerization and the stiffness of the Au dimers. Thus, the intertwinement of quasi-1Dproperties with delocalized 2D effects enforces the atomic wire order.

description: The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states for two-dimensional s- and d-wave superconductors (s- and d-SC) are self-consistently studied under an in-plane magnetic field. While the stripe solution of the order parameter (OP) is found to have lower free energy in s-SC, a square lattice solution appears to be energetically more favorable in the case of d-SC. At certain symmetric sites, we find that the features in the local density of states (LDOS) can be ascribed to two types of bound states. We also show that the LDOS maps for d-SC exhibit bias-energy-dependent checkerboard patterns. These characteristics can serve as signatures of the FFLO states.

description: We report the results of muon-spin spectroscopy ($μ^+$SR) measurements on the staggered molecular spin chain [pym-Cu(NO$_3$)$_2$(H$_2$O)$_2$] (pym = pyrimidine), a material previously described using sine-Gordon field theory. Zero-field $μ^+$SR reveals a long range magnetically-ordered ground state below a transition temperature $T_\mathrm{N}=0.22(1)$ K. Using longitudinal-field (LF) $μ^+$SR we investigate the dynamic response in applied magnetic fields $0< B < 500$ mT and find evidence for ballistic spin transport. Our LF $μ^+$SR measurements on the chiral spin chain [Cu(pym)(H$_2$O)$_4$]SiF$_6 \cdot $H$_2$O instead demonstrate one-dimensional spin diffusion and the distinct spin transport in these two systems likely reflects differences in their magnetic excitations.

description: We prove several results regarding edge-colored complete graphs and rainbow cycles, cycles with no color appearing on more than one edge. We settle a question posed by Ball, Pultr, and Vojtěchovský by showing that if such a coloring does not contain a rainbow cycle of length $n$, where $n$ is odd, then it also does not contain a rainbow cycle of length $m$ for all $m$ greater than $2n^2$. In addition, we present two examples which demonstrate that this result does not hold for even $n$. Finally, we state several open problems in the area.

description: Submillimetre and millimetre observations are important in probing the properties of the molecular gas and dust around obscured active galactic nuclei (AGNs) and their feedback. With very high-resolution (0."02x0."03 (2x3 pc)) ALMA 345 GHz observations of CO 3-2, HCO$^+$ 4-3, HCN 4-3 $ν_2$=1$f$, and continuum we have studied the molecular outflow and nucleus of the extremely radio-quiet lenticular galaxy NGC1377. The outflow is resolved, revealing a 150 pc long, clumpy, high-velocity, collimated molecular jet. The molecular emission is emerging from the spine of the jet with an average diameter of 3-7 pc. A narrow-angle, rotating molecular wind surrounds the jet and is enveloped by a larger-scale, slower CO-emitting structure. The jet and narrow wind are turbulent ($σ>$40 kms$^{-1}$) and have steep radial gas excitation gradients. The jet shows velocity reversals that we propose are caused by precession, or episodic directional changes. We suggest that an important process powering the outflow is magneto-centrifugal driving. In contrast, the large-scale CO-envelope may be a slow wind, or cocoon that stems from jet-wind interactions. An asymmetric, nuclear r$\sim$2 pc and hot (>180 K) dust structure with a high molecular column density, N(H$_2$)$\sim1.8 \times 10^{24}$ cm$^{-2}$, is detected in continuum and vibrationally excited HCN. Its luminosity is likely powered by a buried AGN. The mass of the supermassive black hole (SMBH) is estimated to $\sim9\times10^6$ M$_\odot$ and the SMBH of NGC1377 appears to be at the end of an intense phase of accretion. The nuclear growth may be fuelled by low-angular momentum gas inflowing from gas ejected in the molecular jet and wind. Such a feedback-loop of cyclic accretion and outflows would be an effective process in growing the nuclear SMBH. This result invites new questions as to SMBH growth processes in obscured, dusty galaxies.

description: This study was based on a survey of customers who shopped at a small farmers' market during the summer/fall market season of 1995. Information from a survey completed by 239 shoppers was used to develop a profile of the primary consumer group, defined as those who shop regularly at the market and spend the most per visit. Comparisons between survey data and census data for the local population showed that primary shoppers at the market had higher education, higher annual household income, tended to be slightly older, and were more likely to be employed women. For the most part, the respondents were loyal, weekly shoppers who patronized the market because of the high quality of the products. Most reported that they were willing to pay more for produce at the farmers' market.

High-pressure phase diagram of the exp-6 model: The case of Xenon

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

description: We investigated numerically the high-temperature/high-pressure phase diagram of Xenon as modelled through the exp-6 interaction potential, which is thought to provide a reliable description of the thermal behaviour of rare gases under extreme conditions. We performed a series of extensive NVT Monte Carlo simulations which, in conjunction with exact computation of the solid free energy by the Frenkel-Ladd method, allowed us to precisely locate the freezing and the melting thresholds at each temperature. We find that, under isothermal compression, the exp-6 fluid freezes directly into a FCC solid; however, above 4500 K, an intermediate BCC phase becomes stable in a narrow range of pressures. The chemical potential of the HCP phase does never significantly differ from that of the FCC solid of equal T and P, though the former is found to slightly overcome the latter. We discuss our results in the light of previous numerical studies of the same model system and of the experimental data available for Xenon.

description: Excerpt from the report Summary: For a period of 2 years research in Washington State has accumulated considerable information on methods and costs of loading and moving apples from orchard to the storage and packing plants. Usually this operation is a direct cost to the grower and approximately equals the cost of handling the fruit at the warehouse up to the time the fruit is packed. Several of the methods saved man-hours by using new techniques and thus saved costs as well as time in moving the fruit to storage under the conditions found in that area.

description: Aims. Filamentary structures of early type stars are found to be a common feature of the Magellanic Clouds formed at an age of about 0.9-2*10^8 yr. As we go to younger ages these large structures appear fragmented and sooner or later form young clusters and associations. In the optical domain we have detected 56 such large structures of young objects, known as stellar complexes in the LMC for which we give coordinates and dimensions. We also investigate star formation activity and evolution of these stellar complexes and define the term "starburst region". Methods. IR properties of these regions have been investigated using IRAS data. A colour-magnitude diagram (CMD) and a two-colour diagram from IRAS data of these regions ware compared with observations of starburst galaxies and cross-matching with HII regions and SNRs was made . Radio emission maps at 8.6-GHz and the CO (1 to 0) line were also cross correlated with the map of the stellar complexes. Results. It has been found that nearly 1/3 of the stellar complexes are extremely active resembling the IR behaviour of starburst galaxies and HII regions. These stellar complexes illustrating such properties are called here "starburst regions". They host an increased number of HII regions and SNRs. The main starburst tracers are their IR luminosity (F60 well above 5.4 Jy) and the 8.6-GHz radio emission. Finally the evolution of all stellar complexes is discussed based on the CO emission.

description: The full-heavy tetraquarks $bb\bar{b}\bar{b}$ and $cc\bar{c}\bar{c}$ are systematically investigated within the chiral quark model and the quark delocalization color screening model. Two structures, meson-meson and diquark-antidiquark, are considered. For the full-beauty $bb\bar{b}\bar{b}$ systems, there is no any bound state or resonance state in two structures in the chiral quark model, while the wide resonances with masses around 19.25 GeV and the quantum numbers $J^{P}=0^{+}$, $1^{+}$, and $2^{+}$ are possible in the quark delocalization color screening model. For the full-charm $cc\bar{c}\bar{c}$ systems, the results are qualitative consistent in two quark models. No bound state can be found in the meson-meson configuration, while in the diquark-antidiquark configuration there may exist the resonance states, with masses range between $6.3$ GeV to $7.4$ GeV, and the quantum numbers $J^{P}=0^{+}$, $1^{+}$, and $2^{+}$. And the separation between the diquark and the antidiquark indicates that these states may be the compact resonance states. All these full-charm resonance states are consistent with the latest results at LHCb collaboration and are worth searching in the experiments further.

The analytic form of the kink scaling functions for arbitrary size of the system allows us to describe the flow between the twisted sector of c=1 CFT in the UV region and the massive particles in the IR limit. Kink-creating operators are shown to correspond in the UV limit to disorder fields of the c=1 CFT. The problem of the finite--volume spectrum for generic 2D Landau--Ginzburg models is also discussed.

These definitions might be useful for verifying the quark-gluon-plasma liquid in QCD lattice calculations.

The average von Neumann entropy over such an ensemble has been recently obtained, whereas the main result of this work is an explicit expression of the corresponding variance that specifies the fluctuation around its average. The starting point of the calculations is the connection between correlation functions of the Bures-Hall ensemble and these of the Cauchy-Laguerre ensemble. The derived variance formula, together with the known mean formula, leads to a simple but accurate Gaussian approximation to the distribution of von Neumann entropy of finite-size systems. This Gaussian approximation is also conjectured to be the limiting distribution for large dimensional systems.

description: Single-binary scattering may lead to an exchange where the single object captures a component of the binary, forming a new binary. This has been well studied in encounters between a star--planet pair and a single star. Here we explore the application of the exchange mechanism to a planet--satellite pair and another planet in the gravitational potential of a central star. As a case study, we focus on encounters between a satellite-bearing object and Neptune. We investigate whether Neptune can capture satellites from that object and if the captured satellites have orbits analogous to the Neptunian moons Triton and Nereid. Using $N$-body simulations, we study the capture probability at different encounter distances. Post-capture, we use a simple analytical argument to estimate how the captured orbits evolve under collisional and tidal effects. We find that the average capture probability reaches $\sim$$10\%$ if Neptune penetrates the donor planet's satellite system. Most moons grabbed by Neptune acquire highly eccentric orbits. Post-capture, around half of those captured, especially those on tight orbits, can be circularised, either by tides only or by collisions+tides, turning into Triton-like objects. Captures further out, on the other hand, stay on wide and eccentric orbits like that of Nereid. Both moon types can be captured in the same encounter and they have wide distributions in orbital inclination. Therefore, Triton naturally has a $\sim$50\% chance of being retrograde. A similar process potentially applies to an exoplanetary system, and our model predicts that exomoons can jump from one planet to another during planetary scattering. Specifically, there should be two distinct populations of captured moons: one on close-in circular orbits and the other on far-out eccentric orbits. The two populations may have highly inclined prograde or retrograde orbits.

description: Non-traditional retailers such as warehouse club stores, discount drug stores, and discount mass merchandisers are new competitors for traditional food retailers. It is expected that non-traditional retailers will account for roughly 14 percent of total grocery sales by the turn of the century. The impact of a particular discount mass merchandiser (Wal-Mart) on the sales of a conventional retail grocery outlet (David's Supermarket, Inc.) located in the rural areas surrounding the Dallas/Ft. Worth metroplex is analyzed. In this case study, Wal-Mart alone is responsible for about a 21 percent reduction in sales.

description: We consider a four-vertex model introduced by Bálint Tóth: a dependent bond percolation model on $\mathbb{Z}^2$ in which every edge is present with probability 1/2 and each vertex has exactly two incident edges, perpendicular to each other. We prove that all components are finite cycles almost surely, but the expected diameter of the cycle containing the origin is infinite. Moreover, we derive the following critical exponents: the tail probability $\mathbb{P}$(diameter of the cycle of the origin $>$$n$) $\approx$ $n^{-γ}$ and the expectation $\mathbb{E}$(length of a typical cycle with diameter $n)\approx n^δ$, with $γ=(5-\sqrt{17})/4=0.219...$ and $δ=(\sqrt{17}+1)/4=1.28....$ The value of $δ$ comes from a singular sixth order ODE, while the relation $γ+δ=3/2$ corresponds to the fact that the scaling limit of the natural height function in the model is the additive Brownian motion, whose level sets have Hausdorff dimension 3/2. We also include many open problems, for example, on the conformal invariance of certain linear entropy models.

description: Excerpts from the report: Cotton linters are the short fibers, or fuzz, remaining on cottonseed after the lint cotton has been removed. Annual production of linters in the United States in recent years has been approximately 1-1/2 million bales valued at about 50 million dollars. Linters represented, in the last 10 years, from 8 to 25 percent of the total value of products obtained from cottonseed, the percentage depending on relative prices of the oil, meal, linters, and hulls. This study was conducted with a view to appraising the effect of changes in varieties of cotton planted and harvesting, ginning, and milling practices on the production, marketing, and market outlets for cotton linters. Information was obtained by the survey method from representative oil mill operators, linters dealers, brokers, and converters throughout the United States during the 1951-52 season, and from secondary sources. A majority of the oil mill operators gave primary consideration to demand and relative prices of various qualities of linters in deciding on the quantity and quality of linters to remove from cottonseed. Also considered important were the differences in linters content of various lots of cottonseed and in type of mill processing equipment. More than nine-tenths of the linters produced in 1951-52 were collected by the flue system, and differed substantially in appearance and foreign matter content from linters collected by the condenser system.
Algorithms for Globally-Optimal Secure Signaling over Gaussian MIMO Wiretap Channels Under Interference Constraints

description: Multi-user Gaussian MIMO wiretap channel is considered under interference power constraints (IPC), in addition to the total transmit power constraint (TPC). Algorithms for \textit{global} maximization of its secrecy rate are proposed. Their convergence to the secrecy capacity is rigorously proved and a number of properties are established analytically. Unlike known algorithms, the proposed ones are not limited to the MISO case and are proved to converge to a \textit{global} rather than local optimum in the general MIMO case, even when the channel is not degraded. In practice, the convergence is fast as only a small to moderate number of Newton steps is required to achieve a high precision level. The interplay of TPC and IPC is shown to result in an unusual property when an optimal point of the max-min problem does not provide an optimal transmit covariance matrix in some (singular) cases. To address this issue, an algorithm is developed to compute an optimal transmit covariance matrix in those singular cases. It is shown that this algorithm also solves the dual (nonconvex) problems of \textit{globally} minimizing the total transmit power subject to the secrecy and interference constraints; it provides the minimum transmit power and respective signaling strategy needed to achieve the secrecy capacity, hence allowing power savings.

description: This contribution to a multi-country study of vertical coordination in the hog/pork sector provides a primarily descriptive analysis of coordination of the U.S. hog/pork industry. A common framework of review and analysis is used to facilitate comparison of the industries in Canada, Denmark, Netherlands, and the U.S. The concepts of chain management are used to reach some conclusions regarding the U.S. industry to compete in world markets. Parallel coordination systems are identified. Lack of trust is found to limit development of closer coordination and to limit communication of users' preferences upstream in the sector.
Constraints on Alternatives to Supermassive Black Holes

description: Observations of the centers of galaxies continue to evolve, and it is useful to take a fresh look at the constraints that exist on alternatives to supermassive black holes at their centers. We discuss constraints complementary to those of Maoz (1998) and demonstrate that an extremely wide range of other possibilities can be excluded. In particular, we present the new argument that for the velocity dispersions inferred for many galactic nuclei, even binaries made of point masses cannot stave off core collapse because hard binaries are so tight that they merge via emission of gravitational radiation before they can engage in three-body or four-body interactions. We also show that under these conditions core collapse leads inevitably to runaway growth of a central black hole with a significant fraction of the initial mass, regardless of the masses of the individual stars. For clusters of noninteracting low-mass objects (from low-mass stars to elementary particles), relaxation of stars and compact objects that pass inside the dark region will be accelerated by interactions with the dark mass. If the dark region is instead a self-supported object such as a fermion ball, then if stellar-mass black holes exist they will collide with the object, settle, and consume it. The net result is that the keyhole through which alternatives to supermassive black holes must pass is substantially smaller and more contrived than it was even a few years ago.

description: This paper provides information about the nonagricultural academic job market to students and administrators in Agricultural Economics departments. Particularly, we report the results of a survey sent to 295 non-Land Grant economics departments which met our criteria of offering only a Bachelor's degree in Economics. Of the 101 returned surveys, 45% indicated that they would consider hiring an Agricultural Economist to fill a faculty position within their department. These schools indicated that they place greater value on teaching-related experiences than research publications in prospective faculty members. We propose the implementation of mentoring programs within Agricultural Economics departments. Such programs would allow students to learn valuable teaching skills from a respected professor with a well-established teaching program.

description: Consider the electromagnetic scattering of a time-harmonic plane wave by an open cavity which is embedded in a perfectly electrically conducting infinite ground plane. This paper is concerned with the numerical solutions of the transverse electric and magnetic polarizations of the open cavity scattering problems. In each polarization, the scattering problem is reduced equivalently into a boundary value problem of the two-dimensional Helmholtz equation in a bounded domain by using the transparent boundary condition (TBC). An a posteriori estimate based adaptive finite element method with the perfectly matched layer (PML) technique is developed to solve the reduced problem. The estimate takes account both of the finite element approximation error and the PML truncation error, where the latter is shown to decay exponentially with respect to the PML medium parameter and the thickness of the PML layer. Numerical experiments are presented and compared with the adaptive finite element TBC method for both polarizations to illustrate the competitive behavior of the proposed method.
