description: Collisionless shocks are commonly argued to be the sites of cosmic ray (CR) acceleration. We study the influence of CRs on weakly magnetized relativistic collisionless shocks and apply our results to external shocks in gamma-ray burst (GRB) afterglows. The common view is that the transverse Weibel instability (TWI) generates a small-scale magnetic field that facilitates collisional coupling and thermalization in the shock transition. The TWI field is expected to decay rapidly, over a finite number of proton plasma skin depths from the transition. However, the synchrotron emission in GRB afterglows suggests that a strong and persistent magnetic field is present in the plasma that crosses the shock; the origin of this field is a key open question. Here we suggest that the common picture involving TWI demands revision. Namely, the CRs drive turbulence in the shock upstream on scales much larger than the skin depth. This turbulence generates a large-scale magnetic field that quenches TWI and produces a magnetized shock. The new field efficiently confines CRs and enhances the acceleration efficiency. The CRs modify the shocks in GRB afterglows at least while they remain relativistic. The origin of the magnetic field that gives rise to the synchrotron emission is plausibly in the CR-driven turbulence. We do not expect ultrahigh energy cosmic ray production in external GRB shocks.

description: Footprints of climate change on hydrological behaviour of Jhelum, Upper Indus and Hunza river basins, PakistanJaweria Shamshad, S.R. Ahmad, I. Ahmad, F. AzimBackground: Agriculture based economy of Pakistan is under the direct influence of climate change which can bring substantial changes in characteristics and magnitude of her water resources. Methods: This paper accords the spatio-temporal analysis of impact of climate change on four catchments of Indus, Hunza and Jhelum rivers basins. For this purpose, mix of approaches such as mean monthly analysis of hydro-meteorological variables, Pearson’s and Mann Kendall’s tests, investigation of flow duration curves (FDCs) and Inverse Distance Weighted (IDW) interpolation were used. Results: Results of the study illustrate that there is an increasing trend of winter warming and summer cooling in the studied basins. Discharge is positively controlled by temperature. This effect is more pronounced in case of minimum temperature. With increasing temperature glacier melt is accelerated so runoff is increased both in summer and monsoon seasons. Precipitation controls the magnitude of runoff in basins to a very small extent. In addition, shift in monsoon season owing to transition in temperature and precipitation have been also observed. Examination of flow deviation recommends the availability of maximum discharge during June-September i, e., 79% at Kachura, 75% at Besham Qila, 80% at Dainyor and 53% at Domel. Flow duration curves of the twenty years (1993-2013), report the persistence of flow 22%, 20%, 17% and 7% of time above their respective means at Kachura, Besham Qila, Hunza and Domel. Conclusion: Modification in water resource management in agriculture, irrigation, power and disaster control sectors is strongly felt to cope the challenges of climate change.
Spectroscopic factors, overlaps, and isospin symmetry from an $R$-matrix point of view

subject: FOS: Physical sciences

description: Background: Spectroscopic factors, overlaps, and isospin symmetry are often used in conjunction with single-particle wave functions for the phenomenological analysis of nuclear structure and reactions. Many differing prescriptions for connecting these quantities to physically relevant asymptotic normalization constants or widths are available in the literature, but their relationship and degree of validity are not always clear. Purpose: This paper derives relationships among the above quantities of interest using well-defined methodology and starting assumptions. Method: $R$-matrix theory is used as the primary tool to interoperate between the quantities of interest to this work. Particular attention is paid to effects arising from beyond the nuclear surface, where isospin symmetry is strongly violated. Results: Relationships among the quantities of interest are derived. Example applications of these methods to mirror levels in nucleon+${}^{12}{\rm C}$, nucleon+${}^{16}{\rm O}$, and nucleon+${}^{26}{\rm Al}$ are presented. A new approach to multi-level mirror symmetry is derived and applied to the first three $2^+$ states of ${}^{18}{\rm O}$ and ${}^{18}{\rm Ne}$. Conclusions: The relationship between the quantities of interest is clarified and certain procedures are recommended. It is found that the asymptotic normalization constant of the second $2^+$ state in ${}^{18}{\rm Ne}$ deduced from the mirror state in ${}^{18}{\rm O}$ is significantly larger than found in previous work. This finding has the effect of increasing the ${}^{17}{\rm F}(p,γ){}^{18}{\rm Ne}$ reaction rate in novae.

description: We consider a mechanism of spin decay for an electron spin in a quantum dot due to coupling to a nearby quantum point contact (QPC) with and without an applied bias voltage. The coupling of spin to charge is induced by the spin-orbit interaction in the presence of a magnetic field. We perform a microscopic calculation of the effective Hamiltonian coupling constants to obtain the QPC-induced spin relaxation and decoherence rates in a realistic system. This rate is shown to be proportional to the shot noise of the QPC in the regime of large bias voltage and scales as $a^{-6}$ where $a$ is the distance between the quantum dot and the QPC. We find that, for some specific orientations of the setup with respect to the crystallographic axes, the QPC-induced spin relaxation and decoherence rates vanish, while the charge sensitivity of the QPC is not changed. This result can be used in experiments to minimize QPC-induced spin decay in read-out schemes.

Krill and the Antarctic : finding the balance
Creators: name: Bredesen, Emma Lee
Publisher: name: University of British Columbia
Year: 2009

description: The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) has a mandate to manage Southern Ocean resources using an ecosystem approach. In accordance with this, ecosystem models of the South Orkneys/South Georgia region (FAO Subareas 48.2 and 48.3, respectively) were constructed using the modelling software Ecopath with Ecosim. A model representing the region in the 1990s was used to assess the possible effects that an increased fishery for krill (Euphausia superbd) might have on the ecosystem. The model predicted that the expanded fishery could cause small declines in the biomass of several top predators (<10%), such as Antarctic fur seals and baleen whales, and that bycatch in the krill trawl fishery could reduce some fish populations by almost 35%. Incorporating the natural annual variation in krill biomass into the model showed that predator populations could be negatively affected by years of low krill abundance, which would be further exacerbated by an increased krill fishery. The model also indicated that the traditional concept of the simple Southern Ocean food chain (i.e., primary production, krill, top predator) should be re-evaluated to consider other important intermediary species groups, such as fish and squid. Models representing the region in the past (pre-exploitation, 1900s and 1960s) were used to assess the impacts of commercial sealing, whaling and fishing in the region. Simulations suggest that the increase in Antarctic fur seals since the 1950s was not due to decreased competition for food as a result of the whaling activities in the first half of the 1900s. However, whaling may have had a positive effect on fish population sizes, especially certain commercially important species. Removing large krill predators from the simulated ecosystem, such as birds and seals, did not result in an increase in whales. Removing certain fish groups, however, had more of an acceleratory effect on whale recovery. These findings emphasize the need for a better understanding of the relative roles of species in the Southern Ocean ecosystem, as well as the natural variability of krill abundance, if management issues in the Antarctic are to be resolved.

description: We identify a redundancy between two- and three-nucleon contact interactions at the fourth and fifth order of the chiral expansion respectively. In particular we show that tensor-type and spin-orbit three-nucleon contact interactions effectively account for that part of the two-nucleon interaction which depends on the total center-of-mass momentum and is unconstrained by relativity. This might give the chiral effective field theory enough flexibility to successfully address $A=3$ scattering observables already at N3LO.

description: We examined four evolution paths of the biofuel sector using a partial equilibrium world agricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. The third scenario considers a pure market force driving ethanol demand growth because of the high energy price, while the last is a policy-induced shock with removal of the biofuel tax credit when the energy price is high. Standard results hold where the biofuel sector expands with higher energy price, raising the prices of most agricultural commodities through demand side adjustment channels for primary feedstocks and supply side adjustment channels for substitute crops and livestock. On the other hand, the biofuel sector shrinks coupled with opposite impacts on agricultural commodities with the removal of all support including the tax credit. Also, we find that given distribution bottlenecks, cellulosic ethanol crowds marketing channels resulting in a corn-based ethanol price that is discounted. The blenders’ credit and consumption mandates provide a price floor for ethanol and for corn. Finally, the tight linkage between the energy and agricultural sectors resulting from the expanding biofuel sector may raise the possibility of spillover effects of OPEC’s market power on the agricultural sector.

description: Fake News has become one of the major problems in the society. It is due to its ability to change opinions and cause lot of social and national damage with destructive impacts. Sometimes it gets very difficult to know if the news is genuine or fake. Therefore, it is very important to detect if the news is fake or not. The proposed project uses NLP techniques and Machine Learning to create models which can help to detect fake news. The datasets in the comma separated values format, different attributes like the title and text of the news headline/article were used to perform Fake News Detection. The results show that the proposed solution performs well in terms of providing an output with good accuracy, precision, recall, F1 score. So, the proposed project uses datasets that are trained using count vectorizer method for the detection of fake news and its accuracy will be tested using machine learning algorithms.

description: The effects of biofuel production on commodity prices and their transmission to retail food prices are discussed. Factors driving higher commodity prices are tight global supplies and increased demand of corn ethanol in the short term. Evidence suggests that higher corn prices contribute to food price inflation for some food items. These include eggs, poultry, pork, beef and milk. The findings imply that food price inflation for these items is related to increased production of corn ethanol, primarily because of high oil prices. Higher oil prices also increase fuel and energy costs, which increase marketing costs for all food categories.

description: We propose GM-QAOA, a variation of the Quantum Alternating Operator Ansatz (QAOA) that uses Grover-like selective phase shift mixing operators. GM-QAOA works on any NP optimization problem for which it is possible to efficiently prepare an equal superposition of all feasible solutions; it is designed to perform particularly well for constraint optimization problems, where not all possible variable assignments are feasible solutions. GM-QAOA has the following features: (i) It is not susceptible to Hamiltonian Simulation error (such as Trotterization errors) as its operators can be implemented exactly using standard gate sets and (ii) Solutions with the same objective value are always sampled with the same amplitude. We illustrate the potential of GM-QAOA on several optimization problem classes: for permutation-based optimization problems such as the Traveling Salesperson Problem, we present an efficient algorithm to prepare a superposition of all possible permutations of $n$ numbers, defined on $O(n^2)$ qubits; for the hard constraint $k$-Vertex-Cover problem, and for an application to Discrete Portfolio Rebalancing, we show that GM-QAOA outperforms existing QAOA approaches.

description: Many control applications require that a system be constrained to a particular set of states, often termed as safe set. A practical and flexible method for rendering safe sets forward-invariant involves computing control input using Control Barrier Functions and Quadratic Programming methods. Many prior results however require the resulting control input to be continuous, which requires strong assumptions or can be difficult to demonstrate theoretically. In this paper we use differential inclusion methods to show that simultaneously rendering multiple sets invariant can be accomplished using a discontinuous control input. We present an optimization formulation which computes such control inputs and which can be posed in multiple forms, including a feasibility problem, a linear program, or a quadratic program. In addition, we discuss conditions under which the optimization problem is feasible and show that any feasible solution of the considered optimization problem which is measurable renders the multiple safe sets forward invariant.

description: Trypanothione synthetase (TryS) produces N1,N8-bis(glutathionyl)spermidine (or trypanothione) at the expense of ATP. Trypanothione is a metabolite unique and essential for survival and drug-resistance of trypanosomatid parasites. In this study, we report the mechanistic and biological characterisation of optimised N5-substituted paullone analogues with anti-TryS activity. Several of the new derivatives retained submicromolar IC50 against leishmanial TryS. The binding mode to TryS of the most potent paullones has been revealed by means of kinetic, biophysical and molecular modelling approaches. A subset of analogues showed an improved potency (EC50 0.5–10 µM) and selectivity (20–35) against the clinically relevant stage of Leishmania braziliensis (mucocutaneous leishmaniasis) and L. infantum (visceral leishmaniasis). For a selected derivative, the mode of action involved intracellular depletion of trypanothione. Our findings shed light on the molecular interaction of TryS with rationally designed inhibitors and disclose a new set of compounds with on-target activity against different Leishmania species.

Using a multilevel algorithm and tree-level improvement, we study the behavior of the diffusion coefficient as a function of temperature in the wide range $1.1 < T / T_c < 10^4$ in order to compare it to perturbative expansions at high temperature. We find that within errors the lattice results are remarkably compatible with the next-to-leading order perturbative result.

Two-Phase Emission Detector for Measuring Coherent Neutrino-Nucleus Scattering

Year: 2004

description: Coherent scattering is a flavor-blind, high-rate, as yet undetected neutrino interaction predicted by the Standard Model. We propose to use a compact (kg-scale), two-phase (liquid-gas) argon ionization detector to measure coherent neutrino scattering off nuclei. In our approach, neutrino-induced nuclear recoils in the liquid produce a weak ionization signal, which is transported into a gas under the influence of an electric field, amplified via electroluminescence, and detected by phototubes or avalanche diodes. This paper describes the features of the detector, and estimates signal and background rates for a reactor neutrino source. Relatively compact detectors of this type, capable of detecting coherent scattering, offer a new approach to flavor-blind detection of man-made and astronomical neutrinos, and may allow development of compact neutrino detectors capable of non-intrusive real-time monitoring of fissile material in reactors.

description: Exchange rates have long been thought to have an important impact on the export and import of goods and services, and, thus, exchange rates are expected to influence the price of those products that are traded. At the same time, energy impacts commodity production in some very important ways. The use of chemical and petroleum derived inputs has increased in agriculture over time; the prices of these critical inputs, then, would be expected to alter supply, and, therefore, the prices of commodities using these inputs. Also, agricultural commodities have been increasingly used to produce energy, thereby leading to an expectation of a linkage between energy and commodity markets. In this paper, we examine the price relationship through time of the primary agricultural commodities, exchange rates, and oil prices. Using overlapping time periods, we examine the cointegration relationship between prices to determine changes in the strength of the linkage between markets through time. In general, we find that commodity prices are linked to oil for corn, cotton, and soybeans, but not for wheat, and that exchange rates do play a role in the linkage of prices over time.

description: Background: Like other affected countries around the globe, Malaysia is shocked by the Coronavirus disease 2019, which is also known as COVID-19. Aims: This commentary article discusses the COVID-19 scenario in Malaysia, particularly in relation to the sudden increase in the number of new cases related to an international mass gathering. Findings: Projection through modelling helps the relevant authorities to act quickly and effectively, including enforcement of physical and social distancing. Modelling also assists in understanding the link between the biological processes that underpin transmission events and the population-level dynamics of the disease. Conclusion: There is no one-size-fits-all approach in managing disease outbreak. The fight against COVID-19 very much depends on their attitude during the 14-day Movement Control Order (MCO) which has been extended recently.
Optimal path/neutral [i.e. neural] network approaches to modeling of forest road design for use in automated GIS systems
Creators: name: Aron, Ionut Andrei
Publisher: name: University of British Columbia
Year: 2009

description: A model that integrates the use of feed-forward Artificial Neural Networks and GIS techniques was developed for preliminary road design in forestry. The model was built and tested with GIS data from Malcolm Knapp Research Forest (approximately 5000 ha). Artificial Neural Networks having a variety of architectures were trained using this data, in conjunction with a several different learning parameters. Once the neural networks were trained and tested, the knowledge was used to predict based on new data. The results of these predictions consisted in a numerical representation of the "likelihood" of a given cell to contain a road. The resulting values were represented in GIS format as a new cost - surface. With the addition of this new surface, an optimal path function was run to trace the location of the road. The Artificial Neural Network approach was compared to the classical "Slope - Curvature" approach, traditionally used before in preliminary forest road design with GIS. In all cases, the Artificial Neural Network approach yields better results, both in terms of road length and spatial autocorrelation coefficient. The results of this study suggest that the technique used may be a reasonable method for determining the preliminary road location in forested areas. The roads generated with the aid of Artificial Neural Networks have a higher spatial autocorrelation with the original road and are also shorter than the ones generated with the Slope - Curvature cost surface. The route selected is not perfect from an engineering point of view; however it still can provide good information for the forest road-planner. The route selected by the computer should be modified based on the field inspection and the knowledge and experience of the specialist.

description: Objective: Autoinjectors are a convenient and efficient way to self-administer subcutaneous injections of biopharmaceuticals. Differences in device mechanical design can affect the autoinjector functionality and performance. This study investigates the performance differences of two single-spring-actuated autoinjectors. Methods: We compare the performance between Emgality (120 mg/mL) and Aimovig (140 mg/mL) autoinjector devices from an engineering point of view at two test conditions: room (25 C°) and storage (5 C°) temperatures. We employ a novel experimental procedure to simultaneously acquire the force and acoustic signals during operation, and high-speed imaging during the needle insertion and drug injection. Results: We perform 18 quantitative comparisons between Emgality and Aimovig, and we observe that 14 of these have statistically significant differences. For both test conditions, Emgality requires an 8 N activation force while Aimovig requires 14 N activation force, and the needle of Emgality has an insertion depth of 5 mm while Aimovig has an insertion depth of 7 mm. The injection speeds are significantly affected by temperature. Emgality has an injection speed of 0.40 mL/s and 0.28 mL/s at room and storage temperature condition, respectively; while Aimovig has an injection speed of 0.24 mL/s and 0.16 mL/s at those conditions. Lastly, confirmation “click” sound of Emgality occurs 0.75–1.53 s after dose completion, while in Aimovig, the confirmation “click” sound occurs 0.26-0.46 s before dose completion. Conclusions: This study revealed performance differences between Emgality and Aimovig autoinjector devices, despite the fact that the delivery principle of these single-spring-actuated autoinjectors are the same. These differences may result in different risk of intramuscular injection and premature device removal, both of which need to be further verified in clinical trials.

description: A boundary ring for N=2 coset conformal field theories is defined in terms of a twisted equivariant K-theory. The twisted equivariant K-theories K_H(G) for compact Lie groups (G, H) such that G/H is hermitian symmetric are computed. These turn out to have the same ranks as the N=2 chiral rings of the associated coset conformal field theories, however the product structure differs from that on chiral primaries. In view of the K-theory classification of D-brane charges this suggests an interpretation of the twisted K-theory as a `boundary ring'. Complementing this, the N=2 chiral ring is studied in view of the isomorphism between the Verlinde algebra V_k(G) and twisted K_G(G) as proven by Freed, Hopkins and Teleman. As a spin-off, we provide explicit formulae for the ranks of the Verlinde algebras.

description: The effects of the U.S. dollar exchange rate versus the Mexican peso are evaluated for four traded nonfarm-produced inputs (fertilizer, chemicals, farm machinery, and feed) in the U.S. Unit root tests suggest that the exchange rate and the four input price ratios support the presence of unit roots with a trend model but the presence unit roots can be rejected in the first difference model. This result is consistent with a fixed price/flex price conceptual framework, with industrial prices more likely to be unresponsive to the exchange rate than farm commodity prices.

description: In this work, we compare two powerful parameter estimation methods namely Bayesian inference and Neural Network based learning to study the quark matter equation of state with constant speed of sound parametrization and the structure of the quark stars within the two-family scenario. We use the mass and radius estimations from several X-ray sources and also the mass and tidal deformability measurements from gravitational wave events to constrain the parameters of our model. The results found from the two methods are consistent. The predicted speed of sound is compatible with the conformal limit.

description: The Coronal Global Evolutionary Model (CGEM) provides data-driven simulations of the magnetic field in the solar corona to better understand the build-up of magnetic energy that leads to eruptive events. The CGEM project has developed six capabilities. CGEM modules (1) prepare time series of full-disk vector magnetic field observations to (2) derive the changing electric field in the solar photosphere over active-region scales. This local electric field is (3) incorporated into a surface flux transport model that reconstructs a global electric field that evolves magnetic flux in a consistent way. These electric fields drive a (4) 3D spherical magneto-frictional (SMF) model, either at high-resolution over a restricted range of solid angle or at lower resolution over a global domain, to determine the magnetic field and current density in the low corona. An SMF-generated initial field above an active region and the evolving electric field at the photosphere are used to drive (5) detailed magneto-hydrodynamic (MHD) simulations of active regions in the low corona. SMF or MHD solutions are then used to compute emissivity proxies that can be compared with coronal observations. Finally, a lower-resolution SMF magnetic field is used to initialize (6) a global MHD model that is driven by an SMF electric-field time series to simulate the outer corona and heliosphere, ultimately connecting Sun to Earth. As a demonstration, this report features results of CGEM applied to observations of the evolution of NOAA Active Region 11158 in February 2011.

number of fruits per plant

description: We studied five parental forms of tomato (Solanum Lycopersicum L.). Were obtained twenty F1 hybrids by the complete diallel scheme (5x5) and used to study inheritance on the trait of the "number of fruits per plant". Were used as parental forms in the system of diallel crosses according to Hayman V.I. and Jinks I.J. : the line №477 (sp, u), variety Alya (sp) and three collection samples with high-lycopene tomato: Dark green (hp -2dg), MO 112 (hp) and T-3627 (Bc). The results of the assessment of the general and specific combining ability of the five parental forms of tomato on the trait of the "number of fruits per plant" are presented, established the character of inheritance. In the course of research it was found that the trait "number of fruits per plant" is controlled by the additive-dominant genetic system. Inheritance of a trait occurs by type of overdominance. The dominant role in genetic control of the trait is played by the dominant effects of genes. Dominant genes determined the increase in trait. The best positive significant effects of general combining ability (GCA) had the line №477, samples Dark green and MO 112. They can be recommended for creation of heterosis hybrids and varieties. From hybrid combinations with high values of specific combining ability (SCA): №477 / T-3627, Alya / Dark green, Alya / MO 112, MO 112 / T-3627 it is necessary to make selections for creation of varieties.

description: The M31 satellite galaxy M32 has long been considered an object of unique properties, being the most extreme example of the very rare compact elliptical galaxy class. Here we present the spectroscopic discovery of two M32 twins in the massive galaxy cluster Abell 1689. As these objects are so rare, this is an important step towards a better understanding of the nature of compact galaxies. The two M32 twins had first been detected within our photometric search for ultra compact dwarf galaxy (UCDs) candidates in A1689 (Mieske et al. 2004) with the Advanced Camera for Surveys (ACS). Their luminosities (M_V ~ -17 mag) are very similar to M32 and their surface brightness profiles are consistent with that of M32 projected to A1689's distance. From our ACS imaging we detect several fainter compact galaxy candidates with luminosities intermediate between M32 and the Fornax UCDs. If spectroscopically confirmed as cluster members, this would almost close the gap in the magnitude-surface brightness plane between the region of UCDs and the compact ellipticals, implying a sequence of faint compact galaxies well separated from that of dwarf ellipticals.

description: This study examines the short- and long-run effects of changes in macroeconomic variables—agricultural commodity prices, interest rates and exchange rates—on the U.S. farm income. For this purpose, we adopt an autoregressive distributed lag (ARDL) approach to cointegration with quarterly data for 1989–2008. Results show that the exchange rate plays a crucial role in determining the long-run behavior of U.S. farm income, but has little effect in the short-run. We also find that the commodity price and interest rate have been significant determinants of U.S. farm income in both the short- and long-run over the past two decades.

description: These three invited papers examine the role that exchange rates may have in influencing commodity prices, input prices and farm income. The papers arguably represent one of the most important recent attempts to quantify and explain these new linkages. As U.S. and world agriculture moves from a period of high output prices to a period of lower prices, understanding the impact of macroeconomic variables on farm input costs and farm income will become more important. Further, it will be equally important for policy makers to undertake appropriate market interventions in order to have maximum effectiveness should this period of cost-price-squeeze continue to intensify. Each of the papers has something significant to contribute to the understanding and debate of these new linkages between agriculture, the macroeconomic environment, and the energy sector.
