Publisher: name: INFN Open Access Repository
Year: 2000

description: The TESLA Test Facility (TTF) Injector II photocathode preparation system is in opera-tion since spring 1998. High quantum efficiency tellurium and alkali metals based pho-toemissive films are routinely produced at Milano with typical 10% quantum efficiency (QE). Photocathodes are then successfully transported with no QE degradation, using a handy ultra high vacuum (UHV) system, to DESY and here transferred to the RF gun. The main characteristics of the system and the future developments are here discussed.
title: Phosphorus Mobility in the Shallow Unconfined Aquifer at Pineview Reservoir, Utah
Creators: name: Rumsey, Christine
Publisher: name: Utah State University
Year: 2014

description: Significant phosphorus transport is occurring in the groundwater surrounding Pineview Reservoir. A set of investigations was completed to identify factors contributing to phosphorus mobility. Water quality monitoring was conducted to understand groundwater characteristics and phosphorus movement. Several water quality parameters were evaluated to specifically determine whether septic systems influence groundwater quality. Results indicate that septic systems pollute at least two locations in the aquifer around the reservoir. Given this information, it may be necessary to implement advanced septic system treatment options to reduce the amount of phosphorus in groundwater. Experiments were conducted on two aquifer sediment types to identify factors important for phosphorus mobility. Coarse-grained sand and fine-grained sediments were evaluated, and results showed that phosphorus in both sediments is associated more with calcium minerals than with iron and aluminum minerals. Results suggest calcium is an important factor for immobilizing phosphorus in groundwater at Pineview Reservoir. Iron and manganese oxide concentrations are important for decreasing phosphorus mobility, and experiments showed higher amounts were observed in fine-grained sediments than for coarse-grained sediments. Results of geochemical modeling exercises suggested that sediments may have limited sorption capacity, although at one site, the formation of calcium minerals may provide a continuous source of additional sorption material. Because of suspected septic system influence, the effect of dissolved organic matter on phosphorus mobility was evaluated through a series of laboratory studies. Dissolved organic matter was collected from Pineview Reservoir and used in experiments. Results showed that the presence of dissolved organic matter affected phosphorus sorption minimally, and does not explain P mobility in the shallow unconfined aquifer at Pineview Reservoir.

description: We calculate the rate of creation of double occupancies in a 3D Fermionic Mott insulator near half-filling by modulation of optical lattice potential. At high temperatures, incoherent holes lead to a broad response peaked at the Hubbard repulsion $U$. At low temperatures, antiferromagnetic order leads to a coherent peak for the hole along with broad features representing spin wave shake-off processes. This is manifested in the doublon creation rate as a sharp absorption edge and oscillations as a function of modulating frequency. Thus, modulation spectroscopy can be used as a probe of antiferromagnetic order and nature of quasiparticle excitations in the system.

Determination of the Normal Zone Length in the B0 ATLAS Model Coil
Creators: name: F. Broggi
Publisher: name: INFN Open Access Repository
Year: 2002

description: The ATLAS Barrel Toroid (BT) is a superconducting toroid made of 8 coils of 25 m length and 5 m width, providing the magnetic field for the muon spectrometer of the ATLAS detector, one of the experiments of the Large Hadron Collider, under construction at CERN. In addition to the BT the ATLAS magnetic structure foresees two End Cap Toroid (ECT) with the same 8 structure geometry of the BT, and a Central Solenoid (CS). The B0 construction was decided to test the technical construction solutions and reproduce the behavior of the final coils. The most powerful diagnostic sensors for studies of the quench propagation are the pick-up coils. In this paper a short description of the characteristics of the pick-up coil signal, related to the quench propagation and to the current diffusion from the conductor to the stabilizer is given. Then, from the quench propagation velocity and the pick-up coil signal characteristics, the dimensions of the Normal Zone (NZ), the transited part of the cable, is determined, for different values of the main current in the magnet. The determination of the NZ dimensions is influenced by some experimental parameters, error affected, and by some assumptions. Because of these assumptions the NZ dimensions determined are only indicative, more precise measurements are not so far possible.
Sensitivity of inferences in forensic genetics to assumptions about founding genes

subject: FOS: Computer and information sciences

description: Many forensic genetics problems can be handled using structured systems of discrete variables, for which Bayesian networks offer an appealing practical modeling framework, and allow inferences to be computed by probability propagation methods. However, when standard assumptions are violated--for example, when allele frequencies are unknown, there is identity by descent or the population is heterogeneous--dependence is generated among founding genes, that makes exact calculation of conditional probabilities by propagation methods less straightforward. Here we illustrate different methodologies for assessing sensitivity to assumptions about founders in forensic genetics problems. These include constrained steepest descent, linear fractional programming and representing dependence by structure. We illustrate these methods on several forensic genetics examples involving criminal identification, simple and complex disputed paternity and DNA mixtures.

Peak Finding Through Scan Statistics
Creators: name: F. Terranova
Publisher: name: INFN Open Access Repository
Year: 2003

description: We discuss the conditions under which Scan Statistics can be fruitfully implemented to signal a departure from the underlying probability model that describes the experimental data. It is shown that local perturbations ("bumps" or "excesses" of events) are better dealt within this framework and, in general, tests based on these statistics provide a powerful and unbiased alternative to the traditional techniques related with the  χ^2 and Kolmogorov distributions. Approximate formulas for the computation of Scan Statistics in the range of interest for high energy and nuclear physics applications are also presented.

description: We report measurements on a silicon nanowire quantum dot with a clarity that allows for a complete understanding of the spin states of the first four holes. First, we show control of the hole number down to one. Detailed measurements at perpendicular magnetic fields reveal the Zeeman splitting of a single hole in silicon. We are able to determine the ground-state spin configuration for one to four holes occupying the quantum dot and find a spin filling with alternating spin-down and spin-up holes, which is confirmed by magnetospectroscopy up to 9T. Additionally, a so far inexplicable feature in single-charge quantum dots in many materials systems is analyzed in detail. We observe excitations of the zero-hole ground-state energy of the quantum dot, which cannot correspond to electronic or Zeeman states. We show that the most likely explanation is acoustic phonon emission to a cavity between the two contacts to the nanowire.

description: "PolyCAD", a CAD program designed for X-ray photon tracing in polycapillary optics, is described. To understand the PolyCAD code and its results, the theoretical bases of X-ray transmission by a single cylindrical channel (monocapillary) are discussed first. Then cases of cylindrical, lens and semi-lens shaped polycapillary optics are examined. PolyCAD allows any type of X-ray source to be used: an X-ray tube of finite beam dimensions or an astrophysical object can be simulated in combination with the polycapillary optics. The radiation density distribution images formed on a screen located at various focal distances are discussed. The good agreement of the PolyCAD results with experimental and previous theoretical findings validate the code.
Emergence of small-scale magnetic loops through the quiet solar atmosphere

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We investigate the emergence of magnetic flux in the quiet Sun at very small spatial scales, focusing on the magnetic connection between the photosphere and chromosphere. The observational data consist of spectropolarimetric measurements and filtergrams taken with the Hinode satellite and the Dutch Open Telescope. We find that a significant fraction of the magnetic flux present in internetwork regions appears in the form of Omega-shaped loops. The emergence rate is 0.02 loops per hour and arcsec^{-2}, which brings 1.1 x 10^12 Mx s^{-1} arcsec^{-2} of new flux to the solar surface. Initially, the loops are observed as small patches of linear polarization above a granular cell. Shortly afterwards, two footpoints of opposite polarity become visible in circular polarization within or at the edges of the granule and start to move toward the adjacent intergranular space. The orientation of the footpoints does not seem to obey Hale's polarity rules. The loops are continuously buffeted by convective motions, but they always retain a high degree of coherence. Interestingly, 23% of the loops that emerge in the photosphere reach the chromosphere (16 cases out of 69). They are first detected in Fe I 630 nm magnetograms and 5 minutes later in Mg I b 517.3 nm magnetograms. After about 8 minutes, some of them are also observed in Ca II H line-core images, where the footpoints produce small brightness enhancements.

title: The Effects of Elevation and Vegetation Type on Snow Accumulation and Melt in Logan Canyon, Utah
Creators: name: Thies, Paul R.
Publisher: name: Utah State University
Year: 1973

description: Snow accumulation and melt characteristics were studied in Logan Canyon, Utah. Three replications of aspen, conifer, and open field types at 6300, 7100,and 8000 feet were measured for snow depth and water content during 1972. Elevation was found to have the greatest effect on snow water content. The gradient of increasing water content with rise ln elevation was found to be .51 inches/100 feet in the zone from 6300 to 7100 feet and 1.9 inches/100 feet from 7100 to 8000 feet. The cooler temperatures at higher elevations partially account for the 8000 foot zone beginning to melt 40 days after the 7100 foot zone, and the 7100 foot zone trailing the 6300 foot zone by 20 days. Although the snow at the 8000 foot elevation began melting later than the lower zones, it melted at twice the rate. Vegetation cover type has no significant effect on the amount of snow deposited. However, the conifer type protects the snowpack from solar radiation causing the snowpack to have a significantly lower density than the snowpack assocaited with either aspen or open field. The snowpack under the conifer canopy melts 30 percent slower and remains 17 days longer.

A theoretical background has been given by the TSC-induced nuclear reactions3).

Major reaction will be: M(A,Z) + 4d/TSC  -> M(A+8, Z+4) + Q Theoretical modeling of the process is briefly explained and resulting reaction products, their decays and final stable isotopes are predicted for Cs-137, Sr-90 and Cs-135 transmutations.

description: It is shown that nonlinear terms in equations of gravitons on the background of curved space-time of the expanding Universe can solve the problem of the negative square of the effective mass formally arising in linear approximation for gravitons. Similar to well known spontaneous breaking of symmetry in Goldstone model one must take another vacuum so that nonzero vacuum expectation value of the quantized graviton field leads to change of spectrum for gravitons. There appears two graviton fields, one with the positive mass, another with the zero mass. Energy density and the density of particles created by gravitation of the expanding Universe are calculated for some special cases of the scale factor. Numerical results are obtained for the dust universe case.

Reinforcement learning in partially observable tasks: State uncertainty and memory dependence
Creators: name: Ez-zizi, Adnane
Publisher: name: Zenodo
Year: 2016

description: Reinforcement learning models have been successfully used to explain a wide range of psychological and neural features of human and animal learning behaviour. Themost common reinforcement learning models were initially designed to work in Markovian environments where the currently observed input gives complete knowledgeabout the current state of the system, and where rewards, optimal responses and transitions between states are all dependent on the present state only. However,these conditions are rarely satisfied in the real problems that humans or animals face. In this thesis, we examine how people can deal or actually deal with tasks wherethese conditions are not met; a problem that is often referred to as the problem of partial observability. We consider two types of partial observability: (1) that whichis due to state uncertainty, and (2) that which is due to the dependency of some states on past information, and hence requires some sort of memory. In two separateexperimental studies, we show that people are, in general, able to deal with both these types of partial observability when the tasks involved are simple. In a series ofmodelling studies, we introduce a number of modifications to the Actor-Critic gating model, one of the seminal models for solving memory-dependent partially observabletasks, which substantially improved its learning speed and plausibility as a model of human learning. Our modelling work also generates a number of predictions, whichcan be used to guide future experimental investigations.

description: At stronger gauge-field couplings, the domain wall fermion (DWF) residual mass, a measure of chiral symmetry breaking, grows rapidly. This measure is largely due to near zero fermion eigenmodes of logarithm of the 4D transfer matrix along the fifth dimension, and these eigenmodes increase rapidly at strong coupling. To suppress these eigenmodes, we have added to the DWF path integral a multiplicative weighting factor consisting of a ratio of determinants of Wilson-Dirac fermions having a chirally twisted mass with a large negative real component and a small imaginary chiral component. Numerical results show that this weighting factor with an appropriate choice of twisted masses significantly suppresses the residual mass while allowing adequate topological tunneling.

title: Mercury, Dieldrin, DDT, DDE, and PCB Levels in Tissues From Fish and Wildlife in Utah
Creators: name: Smith, Fred A.
Publisher: name: Utah State University
Year: 1973

description: Fish and wildlife were randomly sampled in Utah from pre-selected x areas and analyzed for levels of total mercury, dieldrin, DDT, and DDE. Levels were well within consumptive tolerance or guideline limits except for mercury levels of fish in Willard Bay Reservoir. PCB's were also identified in a large proportion of samples. None of the chukars, 6 percent of the pheasants, 4 percent of the waterfowl, and none of the fish sampled, excluding Willard Bay Reservoir, were above the 0.5 ppm guideline level for mercury established by the Food and Drug Administration. Seventy-seven percent of the fish sampled from Willard Bay Reservoir were above the 0.5 ppm guideline level. Only one duck (2 percent) was above the maximum permissible concentration for dieldrin. All of the chukars, pheasants, other waterfowl, and fish were well below human consumptive tolerance limits for dieldrin and DDT + DDE. It is recommended that studies be initiated to more closely define possible sources of mercury and the health hazard involved in consumption of these fish.

description: We experimentally study the transport features of electrons in a spin-diode structure consisting of a single semiconductor quantum dot (QD) weakly coupled to one nonmagnetic (NM) and one ferromagnetic (FM) lead, in which the QD has an artificial atomic nature. A Coulomb stability diamond shows asymmetric features with respect to the polarity of the bias voltage. For the regime of two-electron tunneling, we find anomalous suppression of the current for both forward and reverse bias. We discuss possible mechanisms of the anomalous current suppression in terms of spin blockade via the QD/FM interface at the ground state of a two-electron QD.

description: Two soils were used in this soil column study. Yolo loam soil a non- c al c areous, non-gypsiferous soil from central California and Vernal soil a calcareous soil from eastern Utah. Initial studies were conducted where the solubilities of pure CaC0 3 and CaS0 4 ' 2H 2 0 were determined in the presence of Logan river water, a KCl solution (2.8 mmhos/cm) and a K 2 S0 4 solution (Z. 7 mmhos/cm). Gypsum was more soluble in the KCl solution than in the K Z S0 4 solution. The solubility product of both gypsum and lime were determined from the analytical data. The formation of CaS0 4 0 and caco 3 0 ion pairs were cons idered to be the most important complex ions pres ent. A reasonable agreement was observed between the theoretical values of K and the ca lculated K sp sp Essentially the same results were obtained when these waters were used in leaching the columns of Yolo and Vernal soil columns The solubility of gypsUJn was greatest usmg the KCl leaching' solution and least using the K 2504 leaching solution. Logan river water gave intermediate values. Calcium carbonate was most soluble in the K 2504 leaching solution and les s in the KCl solution. It was found that measuring the ci+ concentration in the effluent was a more reliable index to steady state condition than using an electrical conductivity lneasurement. Unsaturated flow removed more salt per unit volume of effluent than saturated flow. The relative area method was used to analyze the effluent under saturated moisture flow. 2+ It was found that a certain amount of Ca derived from gypsum dissolution precipitated in the column as CaC0 3 . This amount 2+ , was greater than 15% of the Ca dlssolved from gypsum.

description: We present a non-perturbative study of the phase diagram of 5d SU(2) Yang-Mills theory with one compact extra dimension on the lattice. Assuming at least a modest scale separation between the cutoff and the compactification scales leads to an exponential separation between the compactification scale and the four-dimensional correlation length. While we demonstrate that it is not possible to take a full five-dimensional continuum limit, this dynamical generation of scale hierarchy opens up the possibility for us to make limited, but non-perturbative, predictions about continuum theories whose low-energy sector is described by an effective 5d Yang-Mills theory.

Publisher: name: Utah State University
Year: 1973

description: The purpose of this study was to determine empirically if crossbreeding offers a more profitable alternative to Utah cattlemen than vii straightbreeding. Ranchers practicing breed crossing were interviewed to determine the relative merits of crossbreeding and straightbreeding in the categories of calf crop, weaning weight, sale price, and minor economic factors under ranch conditions. Crossbred and straightbred sale prices \.,ere analyzed utilizing the records of the Smithfield Livestock Auction. Analysis of rancher interview data indicated that crossbred animals exceeded straightbreds in weaning weight and sale price. Crossbreds were further credited with lowering herd disease levels. No generalizations from comparative calf crop were feasible. Analysis of auction data found no conclusive evidence of price differentiation between crossbreds and straightbreds.

description: Five day old dark-grown seedlings of Secale cereale variety "coup;ar" p:rown at 20 C were subjected to hardening at 2 C "!.n daily increments from 0 to 7 days, to temperature stress at -5 C for 0, 1, and 3 days, and to recovery at 20 C for 0, I, and J days. Unhardened plants were killed by temperature stress but as the time of hardening increased fewer plants were killed. After 5 days of hardening all plants survived subsequent freezing stress. Mitochondria were isolated from the plants after they received various combinations of the three temperature treatments. There were 8 hardening levels, 3 stress levels, and 3 recovery levels giving a total of 8x3x30 72 treatments. Mitochondria from unstressed plants exhibited steady ADPIO ratios, RC ratios, and rate of state 3 respiration over the whole range of hardening and recovery times. Mitochondria from stressed plants were totally inactive with 0 or one day of hardening but as the time of hardening increased so did ADP: O ratio, R~ ratio, and ratp of state J respiratIon. After 5 days of hardenjng mitochondrla from hardened then stressed plants reached a maxImum level of activity. Evidently there was some change 1n the mttochondria during the hardening phase.

description: This paper presents a method for determination of interference filter parameters such as the effective refraction index and the maximal transmittance wavelength on the basis of image processing of a spectrogram produced by Spectrometer Airglow Temperature Imager instrument by means of data processing. The method employs the radial sections for determination of points from the crests and valleys in the spectrograms. These points are involved in the least square method for determination of the centres and radii of the crests and valleys. The use of the image radial sections allows to determine the maximal number of crests and valleys in the spectrogram. The application of the least square fitting leads to determination of the image centers and radii of the crests and valleys with precision higher than one pixel. The nocturnal course of the filter parameters produced by this method is presented and compared with that of the known ones. The values of the filter parameters thus obtained are closer to the laboratory measured ones.

description: A potato varietal trial, the equivalent of the final step in a potato breeding and testing program was conducted in 1972 at the Farmington Experimental Sub-station, Farmington, Utah. The test consisted of twelve named varieties and two numbered selections. This study measured the yielding capacity of new potato varieties and selections during one growing season at one location in Utah. Yields were compared with those of the older accepted varieties grown in the state and used as control or standard varieties in the varietal trial. This study provided valuable information for growers and processors in determining the suitability of these varieties for production in Utah. Data was obtained on total yield; yield and percentage of U.S. No.1 potatoes over and under 3 inches in diameter or 10 ounces in weight; U.S. No.2 and culls and small potatoes under 1 7/8 inches in diameter; the incidence of hollow heart and internal discoloration and chipping quality of certain varieties. LaRouge and Chieftain were significantly higher than Red Pontiac in yield of U.S. No.1 potatoes. LaChipper, Abnaki, ND 7196-18, Platte and Shurchip were significantly higher than Raritan, Norchip and Kennebec. The incidence of hollow heart in Abnaki, Raritan, LaChipper and ND 6925- 13 Russ was significantly higher than the other ten varieties in the test. The percentage of internal discoloration in selection ND 6925-13 Russ was signifi cantly higher than all other varieties tested. Norchip and selection ND 7196-18 produced light colored chips on both chipping dates.

title: Economic Analysis of the Agricultural Sector in Santa Cruz, Bolivia
Creators: name: Gómez, Enrique
Publisher: name: Utah State University
Year: 1974

description: A linear programming technique is used to calculate the land allocation that maximizes the returns to the agricultural producers in the provinces Santisteban, Sara, Warnes, Ibanez, and Ichilo, in the department of Santa Cruz, Bolivia, under different sets of prices. All the input requirements per unit of land and average expected yields are estimated from survey data collected from farmers in Bolivia. Constraints on availability of land and labor are also estimated. Seven crops are included in the model: soybeans, wheat, cotton, yuca, sugar cane, rice, and corn. The model is first examined under the set of prices that existed prior to the 67 percent devaluation of the Bolivian currency of October 1972. Supply schedules are calculated for each one of the crops. Later, the price changes caused by the devaluation are introduced into the model, and their impact upon the "optimum" land allocation in the area is ascertained. A supply curve is derived for cotton under "after devaluation" prices. The effect of an export tax, on land utilized for cotton production is analyzed. It is estimated that a 40 percent tax on cotton production, other things being equal, would render cotton production unprofitabl e . A 23 percent tax would maximize the Government tax revenues. The net social cost of implementing such a tax is estimated at $b 101.6 millions per year. A self-sufficiency national policy is examined for wheat production. If the Government desires self-sufficiency in wheat production while maintaining the real price to the consumers at the pre-devaluation level, (that is, $b 46.75 per cwt before devaluation, and $b 70.12 per cwt after) the producers would have to be paid $b 150.0 per cwt, the difference between the pegged consumer price and the price paid to producers being covered by a Government subsidy. The total cost to the Government for the subsidy is estimated at $b 642.7 millions per year, and the net social loss is $b 141.2 millions per year.
title: Primary Production in a Cache Valley, Utah Farm Pond
Creators: name: Summers, J. Kent

description: Primary production was measured on a 9.5 acre Cache Valley, Utah farm pond from July 1971 to July 1972. Polyethylene film tubes, with lids, were used to confine columns of water for determining dissolved oxygen concentration. Once a week, dissolved oxygen samples were taken at sunset, the following sunrise and sunset. Annual primary production was estimated at 1289 grams oxygen per square meter for two of the four stations, and 927 grams oxygen per square meter for the remaining two stations. The weekly data was computed at once a month intervals to see if it would be possible to get a good estimate of primary production sampling only 12 times a year~ It was found that the stations with consistent limiting factors could have been sampled once a month with good results, but stations with fluctuating limiting factors could not be sampled that way for good results.
title: Breeding Bird Populations and Habitat Utilization in Aspen Stands of Upper Logan Canyon
Creators: name: Young, Janet L.
Publisher: name: Utah State University

description: Censuses of two 20-acre plots in upper Logan Canyon, Utah, were made by the spot-mapping method during 1970 and 1971 to determine the differences in composition and density of breeding-bird populations in aspen stands of significantly different density and stature. The less dense stand of greater average d.b.h., average height and per cent ground cover had 20 breeding species totalling 615 pairs per 100 acres (expressed as equivalent territories). The more dense stand of smaller trees and brushy undergrowth had 14 breeding species with 267.5 equivalent territories per 100 acres. Nine species were found on both areas. Observations of foraging height were made concurrently with recordings of time spent at various methods of feeding- ground, vi foliage, bark, hover, and hawking- for the birds of the more open stand. Comparison showed that more ground- and low bush-nesters were present on the dense, brushy stand whereas more cavity-nesters were found in the larger trees. Cavity excavation was limited to trees of greater d.b.h. and cavity-dependent birds were thus limited by nest-hole availability. The horizontal, heavy branch stubs preferred by pewees and tree swallows and the high perches and open areas of the olive-sided flycatcher were also limited to the less dense stand. Cassin's finches and pine siskins were not found in the dense stand which had fewer invading conifers and was farther from conifer stands. Attributes of the terrain, foraging sites, nest sites, and location of perches were analyzed as possible proximate factors of habitat selection within aspen.

description: We consider the manipulation of Bose-Einstein condensate vortices by optical potentials generated by focused laser beams. It is shown that for appropriate choices of the laser strength and width it is possible to successfully transport vortices to various positions inside the trap confining the condensate atoms. Furthermore, the full bifurcation structure of possible stationary single-charge vortex solutions in a harmonic potential with this type of impurity is elucidated. The case when a moving vortex is captured by a stationary laser beam is also studied, as well as the possibility of dragging the vortex by means of periodic optical lattices.
title: The Effects of Policy Development and Organizational Structure on the Performance of Range Livestock Development Projects in Africa
Creators: name: Perrier, Gregory Karl
Publisher: name: Utah State University
Year: 1991

description: Range professionals are frequently involved in the arrangement of range development projects, both domestically and internationally. '!he success record of such projects has been uneven, particularly for projects in developing nations. The objective of this study was to provide range specialists a better understanding of potential management obstacles and barriers to success. This is accomplished through an examination of the management of three AID-funded pastoral development projects in Africa: the Tanzanian Masai Livestock and Range Management Project, the Somali Central Rangelands Development Project, and the Lesotho Lard Conservation and Range Development Project. The study examined the effects of two important aspects of project management, organizational structure and goal and strategy development, on project performance. Findings indicated two major themes: project performance is improved by actions that 1) increase flexibility and 2) result in appropriate strategies. Flexibility was increased by support from politically powerful institutions (e.g., powerful ministries, donors, etc.), ability to modify internal structures and external linkages to other organizations during implementation, ability to modify strategy during implementation, devolution of operational decision-making to field levels, allowing field staff control over the resources needed to implement their activities, and participation in decision-making by pastoralists. Appropriate strategies are those having a high congruence with the interests of key actors (i. e., donors, national ministries, local administrators, pastoralists) , with pastoral household goals and extant production strategies, with the resources and capabilities locally available, and with inten1al structures and external linkages

description: We provide a framework for calculating holographic Green's functions from general bilinear actions and fields obeying coupled differential equations in the bulk. The matrix-valued spectral function is shown to be independent of the radial bulk coordinate. Applying this framework we improve the analysis of fluctuations in the D3/D7 system at finite baryon density, where the longitudinal perturbations of the world-volume gauge field couple to the scalar fluctuations of the brane embedding. We compute the spectral function and show how its properties are related to the quasinormal mode spectrum. We study the crossover from the hydrodynamic diffusive to the reactive regime and the movement of quasinormal modes as functions of temperature and density. We also compute their dispersion relations and find that they asymptote to the lightcone for large momenta.

Merging and Splitting of Clusters in the Electromagnetic Calorimeter of the KLOE Detector
Creators: name: Jaroslaw Zdebik
Publisher: name: INFN Open Access Repository
Year: 2008

description: The work was carried out in the framework of the KLOE collaboration studying the decays of the phi meson produced in the DAFNE accelerator in the collisions of electron and positron. The main aim of this thesis was investigation of the influence of the merging and splitting of clusters in decays with the high multiplicity of gamma quanta, which are at most biased by these effects. For this aim we implemented the full geometry and realistic material composition of the barrel electromagnetic calorimeter in FLUKA package. The prepared Monte Carlo based simulation program permits to achieve a fast generation of thedetector response separately for each interested reaction. The program was used to study the reconstruction efficiency with the KLOE clustering algorithm as a function of the photocathode quantum efficiency. It was also used to investigate merging and splitting probabilities as a function of the quantum efficiency. The conducted studies indicated that the increase of quantum efficiency does not improve significantly the identification of clusters. The influence of these effects was estimated for eta meson decays into 3 neutral pions and K_short meson into 2 neutral pions.

description: There are differences in the gut microbiota between IBD (including CD and UC) patients and healthy individuals, and these differences are related to factors such as age and BMI. Here, we perform sequencing for a cohort containing UC, CD patients and healthy individuals, and analyze the impact of these factors on IBD patients from the perspective of both microbiota and microbial function.
GRB990705: a Detectable Neutrino Source?
Creators: name: LVD Collaboration
Publisher: name: INFN Open Access Repository
Year: 1999

description: The detection of the Gamma Ray Burst GRB990705 on July 5th 1999,pointing to the Large Magellanic Clouds, suggested the search for the possible existence of a neutrino signal, either in coincidence or preceding the photon burst. We investigated this possibility by mean of the LVD neutrino telescope at the Gran Sasso Underground Laboratories. No evidence of a neutrino signal either simultaneous or preceding the GRB has been found, hence we set upper limits on the nuebar flux cross-section product. Assuming thermal nuebar spectra, the results are expressed in terms of limits on the nuebar flux for different spectral temperatures.
