description: We define a pseudorandom function (PRF) $F: \mathcal{K} \times \mathcal{X} \rightarrow \mathcal{Y}$ to be bi-homomorphic when it is fully Key homomorphic and partially Input Homomorphic (KIH), i.e., given $F(k_1, x_1)$ and $F(k_2, x_2)$, there is an efficient algorithm to compute $F(k_1 \oplus k_2, x_1 \ominus x_2)$, where $\oplus$ and $\ominus$ are (binary) group operations. The homomorphism on the input is restricted to a fixed subset of the input bits, i.e., $\ominus$ operates on some pre-decided $m$-out-of-$n$ bits, where $|x_1| = |x_2| = n$, and the remaining $n-m$ bits are identical in both inputs. In addition, the output length, $\ell$, of the operator $\ominus$ is not fixed and is defined as $n \leq \ell \leq 2n$, hence leading to Homomorphically induced Variable input Length (HVL) as $n \leq |x_1 \ominus x_2| \leq 2n$. We present a learning with errors (LWE) based construction for a HVL-KIH-PRF family. Our construction is inspired by the key homomorphic PRF construction due to Banerjee and Peikert (Crypto 2014). An updatable encryption scheme allows rotations of the encryption key, i.e., moving existing ciphertexts from old to new key. These updates are carried out via \emph{update tokens}, which can be used by an untrusted party since the update procedure does not involve decryption of the ciphertext. We use our novel PRF family to construct an updatable encryption scheme, named QPC-UE-UU, which is quantum-safe, post-compromise secure and supports unidirectional ciphertext updates, i.e., the update tokens can be used to perform ciphertext updates but they cannot be used to undo already completed updates. Our PRF family also leads to the first left/right key homomorphic constrained-PRF family with HVL.

description: In this article, we study freeness of hyperplane arrangements. One of the most investigated arrangement is a graphic arrangement. Stanley proved that a graphic arrangement is free if and only if the corresponding graph is chordal and Dirac showed that a graph is chordal if and only if the graph is obtained by "gluing" complete graphs. We will generalize Dirac's construction to simple matroids with modular joins introduced by Ziegler and show that every arrangement whose associated matroid is constructed in the manner mentioned above is divisionally free. Moreover, we apply the result to arrangements associated with gain graphs and arrangements over finite fields.

description: This study examined the communication sources used by farmers in handling poultry diseases. Using random and stratified sampling techniques, 8 villages and 80 farmers were used for this study. Structured questionnaire and interview schedule were used to collect data. Data were analysed through use of percentages, mean scores and regression analysis. It was found that veterinary officers, friends and contact farmers were the major sources of communication used by the farmers in handling poultry diseases. Regulated movement of unauthorized persons, use of foot bath at entrance of poultry house, and battery cages for good litter management were the least techniques adopted by the farmers for poultry disease prevention. On the other hand, the techniques mostly adopted for disease prevention were good ventilation and hygiene, vaccination of birds and application of antibiotics in drinking water and feed. The result of regression analysis showed that veterinary officers, agricultural extension workers and friends made significant contribution to adoption of poultry disease prevention techniques. Broadcast media programmes on livestock production should be initiated and aired twice a week to provide critical information on poultry disease management to farmers.

description: The paper examines trends and drivers for regional specialization of China’s agricultural produc-tion for 2003-2011. We apply the Regional Specialization Index to a data set of commodities that covers 70 percent of China’s crop and livestock production. Actual prices at the provincial level are used and a seven-region framework is established that accurately reflects China’s agro-ecological characteristics. Our findings show that inequality of specialization among the Chinese regions has narrowed, with the year 2007 as a turning point. We argue that the enhanced regional specialization is due to less government intervention and more openness to international markets. Growing economic freedom, accompanied by intensified internal and external competition, has driven the regions to adjust agricultural production structures closely according to comparative advantages. Recent trends of specialization are identified and explained. Moreover, quantitative evidence to relevant agricultural policies is provided.

description: Pre-tested, structured questionnaires covered management aspects, inputs, outputs, socio-economic situations and constraints in dairy farming among Semi-intensive (SIFS) and Extensive farming systems (EFS) in dry-lowland Sri Lanka. Parametric data were analyzed using two-tailed‘t’ and ‘Z’ tests, and non-parametric values were analyzed using Chi-square and Fisher’s extract tests. Cobb-Douglas model was used to calculate meta-frontier and system-specific frontiers. Returns in SIFS are lower than EFS. Labor costs are 91.72% and 87.26% in EFS and SIFS respectively. Counting family labor, SIFS has no comparative surplus. Excluding this, dairying is profitable even in SIFS. Dairying provides EFS family insurance where selling animals increases income. Discouragement of this in SIFS impacts negatively on sustainable income. Integration is comparatively minimal in EFS. Established with the best practices and technologies available, SIFS requires external resources to enhance efficiencies. If all EFS farmers achieved best farmer TE, output could increase by 45.09%. Similarly, SIFS output could increase by 57.08%. Farmer education and training programs contribute to improved production efficiency. Grassland scarcity and low productivity affect output adversely; poor veterinary and extension services are major constraints. Farmers consider dairying as profitable, which secures its future. Contrastingly, 35.19% of farmers believe it is low status, preferring professional jobs despite lower comparative incomes.

description: In 2007 a multilocational trial was conducted in a split-plot using randomized complete block University of Maiduguri and Gashua Farm station to assess the effects of fungicide and seed rate on the incidence of leaf blast (Magnaphorte grisea), on the growth and yield of foxtail millet in the Northeastern Nigeria. The results showed that the lowest disease incidence of 20.8% and 0.4% were recorded from 100% recorded significantly (P < 0.05) the highest disease incidence of 80.0% and 64.3% at Maiduguri and Gashua respectively. The highest plant height and panicle length were recorded from plants grown at fungicide seed treatment ranging from 80-100% at seed rate of 5.0kg/ha. The lowest plant height and panicle length were obtained from plants grown from the untreated seed tate of 12.5kg/ha and while the lowest grain yields were recorded from untreated seed rate of 5.0kg/h at Maiduguri and Gashua respectively.

description: The present study was conducted with a view to analyzed growth and trend in area, production and yield of major crops of Khyber Pakhtunkhwa. A time series data from 1980-81 to 2011-12 (32 years) of major crops (wheat, maize, rice and sugarcane) were collected. The compound growth rate as well as trend analysis indicated that the area under wheat crop has decreased over the time due to shifting of area to other rabi crops. The production of wheat during 1981-85 to 2010-12 was increased due the corresponding increase in per hectare yield of wheat crop in Khyber Pakhtunkhwa. The results show that area, production and yield of maize was increased over the time the reason is that more area was brought under hybrid and improved open pollinated maize varieties. The area under rice crop has decreased whereas their production increased due the corresponding increase in per hectare yield of rice crop. It was revealed from the results that area, production and yield of sugarcane crop was increasing at a rate of 0.24 percent, 0.85 percent and 0.60 percent per annum, respectively.
More concerning the anelastic and subseismic approximations for low-frequency modes in stars
Creators: name: Rieutord, M.
name: Dintrans, B.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)

description: Two approximations, namely the subseismic approximation and the anelastic approximation, are presently used to filter out the acoustic modes when computing low frequency modes of a star (gravity modes or inertial modes). In a precedent paper (Dintrans & Rieutord 2001), we observed that the anelastic approximation gave eigenfrequencies much closer to the exact ones than the subseismic approximation. Here, we try to clarify this behaviour and show that it is due to the different physical approach taken by each approximation: On the one hand, the subseismic approximation considers the low frequency part of the spectrum of (say) gravity modes and turns out to be valid only in the central region of a star; on the other hand, the anelastic approximation considers the Brunt-Vaisala frequency as asymptotically small and makes no assumption on the order of the modes. Both approximations fail to describe the modes in the surface layers but eigenmodes issued from the anelastic approximation are closer to those including acoustic effects than their subseismic equivalent. We conclude that, as far as stellar eigenvalue problems are concerned, the anelastic approximation is better suited for simplifying the eigenvalue problem when low-frequency modes of a star are considered, while the subseismic approximation is a useful concept when analytic solutions of high order low-frequency modes are needed in the central region of a star.

description: Aims. We aim to determine the geometry, density gradient, and velocity structure of jets in post-asymptotic giant branch (post-AGB) binaries. Methods. Our high cadence time series of high-resolution optical spectra of jet-creating post-AGB binary systems provide us with a unique tomography of the jet. We determine the spatio-kinematic structure of the jets based on these data by fitting the synthetic spectral line profiles created by our model to the observed, orbital phase-resolved, Hα-line profiles of these systems. The fitting routine is provided with an initial spectrum and is allowed to test three configurations, derived from three specific jet launching models: a stellar jet launched by the star, an X-wind, and a disk wind configuration. We apply a Markov-chain Monte Carlo routine in order to fit our model to the observations. Our fitting code is tested on the post-AGB binary IRAS19135+3937. Results. We find that a model using the stellar jet configuration gives a marginally better fit to our observations. The jet has a wide half-opening angle of about 76 degrees and reaches velocities up to 870 km/s. Conclusions. Our methodology is successful in determining some parameters for jets in post-AGB binaries. The model for IRAS19135+3937 includes a transparent, low density inner region (for a half-opening angle < 40 degrees). The source feeding the accretion disk around the companion is most likely the circumbinary disk. We will apply this jet fitting routine to other jet-creating post-AGB stars in order to provide a more complete description of these objects.

On the formation of oxygen-neon white dwarfs in close binary systems

description: The evolution of a star of initial mass 10 $M_{\odot}$, and metallicity $Z = 0.02$ in a Close Binary System (CBS) is followed from its main sequence until an ONe degenerate remnant forms. Restrictions have been made on the characteristics of the companion as well as on the initial orbital parameters in order to avoid the occurrence of reversal mass transfer before carbon is ignited in the core. The system undergoes three mass loss episodes. The first and second ones are a consequence of a case B Roche lobe overflow. During the third mass loss episode stellar winds may play a role comparable to, or even more important than Roche lobe overflow. In this paper, we extend the previously existing calculations of stars of intermediate mass belonging to close binary systems by following carefully the carbon burning phase of the primary component. We also propose different possible outcomes for our scenario and discuss the relevance of our findings. In particular, our main result is that the resulting white dwarf component of mass $1.1 M_\odot$ more likely has a core composed of oxygen and neon, surrounded by a mantle of carbon-oxygen rich material. The average abundances of the oxygen-neon rich core are $X({\rm O}^{16})=0.55$, $X({\rm Ne}^{20})=0.28$, $X({\rm Na}^{23})=0.06$ and $X({\rm Mg}^{24})=0.05$. This result has important consequences for the Accretion Induced Collapse scenario. The average abundances of the carbon-oxygen rich mantle are $X({\rm O}^{16})=0.55$, and $X({\rm C}^{12})=0.43$. The existence of this mantle could also play a significant role in our understanding of cataclysmic variables.

description: This research has been carried out to identify correlations between the shedding and growth dynamics of yak down wool and the ecological conditions of yak habitat. According to the research, the location of the aimags and soums where yak herds are bred in large cold Khangai mountains, with an average altitude of 2000-3300m above sea level. The average winter temperatures dropping to between -300C and -400C and average summer temperature +120C to +200C. In order to survive such harsh environment, the down wool between the coarse top hair fibres grows intensively on yaks at the start of the cold season; throughout winter a yak’s body is covered with down wool with a complete morphological structure consisting of coarse down and mid- type fibres, enabling yaks to withstand cold temperatures. With the onset of spring and warmer temperatures, the hair fibres are gradually shed until June, when new fibres appear. However, the growth of new fibres slows down in the months of July and August, intensifying with the approach of colder months. The research reveals that the adaptive capacity of yaks to the ecological conditions of their habitat affects the renewal process of the morphological structure of yak down.

description: The study examined the cost and return of plantain production in Orhionmwon Local Government Area, Edo State. Multi-stage sampling procedure was used to select 40 plantain farmers from two clans in the study area. Data required for the study were generated using questionnaire and interview schedule. Information generated was coded and analyzed using descriptive statistics, gross margin analysis, t-ratio statistic and likert scale method. The finding shows that plantain production is a very profitable enterprise and that for every one naira invested in plantain production, there is a return on investment of about N12.60 kobo. The result shows that the farmers are relatively young with majority (90 percent) below 54 years of age. About 45 percent of farmers acquired formal education. The study indicates that both male and female were engaged in plantain production enterprise. Total cost of production was N37, 983 with the variable cost item as the major component while the fixed cost was (3,934). There was a net profit of N36, 421.70. The result also shows that plantain production is affected by farm size and also that output is corrected to farm size too.

description: Background charge fluctuators are studied individually by means of a modified single-electron pump. Operation of the device in a feedback mode allows electrometric sensing of the charged background and its behavior upon electric potential variations due to geometrically different gates. Pulse height spectra and hysteresis of charge trapping transitions are discussed as a specific signature of distinct fluctuators. The location of individual traps is determined from the experimental data and based on electrostatic calculations.
Spectral functions in the sigma-channel near the critical end point

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Spectral functions in the $σ$-channel are investigated near the chiral critical end point (CEP), that is, the point where the chiral phase transition ceases to be first-ordered in the $(μ,T)$-plane of the QCD phase diagram. At that point the $σ$ meson becomes massless in spite of explicit breaking of the chiral symmetry. It is expected that experimental signatures peculiar to CEP can be observed through spectral changes in the presence of abnormally light $σ$ mesons. As a candidate, the invariant-mass spectrum for diphoton emission is estimated with the chiral quark model incorporated. The results show the characteristic shape with a peak in the low energy region, which may serve as a signal for CEP. However, we find that the diphoton multiplicity is highly suppressed by infrared behaviors of the $σ$ meson. Experimentally, in such a low energy region below the threshold of two pions, photons from $π^0\to2γ$ are major sources of the background for the signal.

description: We define a magic square to be a square matrix whose entries are nonnegative integers and whose rows, columns, and main diagonals sum up to the same number. We prove structural results for the number of such squares as a function of the size of the matrix and the line sum. We give examples for small sizes and show similar results for symmetric, pandiagonal magic squares, and magic hypercubes.

description: In this paper, we report a generation of a spin-wave excitation (SWE) with a near-unity () probability in a given time (~730). Such deterministic generation relies on a feedback scheme with a millisecond quantum memory. The millisecond memory is achieved by maximizing the wavelength of the spin wave and storing the SWE as the magnetic-field-insensitive transition. We then demonstrate partial retrievals of the spin wave by applying a first read pulse whose area is smaller than the value of . The remained SWE is fully retrieved by a second pulse. Anti-correlation function between the detections in the first and second readouts has been measured, which shows that the partial-retrieval operation on the SWE is in the quantum regime. The presented experiment represents an important step towards the realization of the improved DLCZ quantum repeater protocol proposed in Phys. Rev. A 77, 062301 (2008).

description: We report the discovery of nineteen new HI shells in the Southern Galactic Plane Survey (SGPS). These shells, which range in radius from 40 pc to 1 kpc, were found in the low resolution Parkes portion of the SGPS dataset, covering Galactic longitudes l=253 deg to l=358 deg. Here we give the properties of individual shells, including positions, physical dimensions, energetics, masses, and possible associations. We also examine the distribution of these shells in the Milky Way and find that several of the shells are located between the spiral arms of the Galaxy. We offer possible explanations for this effect, in particular that the density gradient away from spiral arms, combined with the many generations of sequential star formation required to create large shells, could lead to a preferential placement of shells on the trailing edges of spiral arms. Spiral density wave theory is used in order to derive the magnitude of the density gradient behind spiral arms. We find that the density gradient away from spiral arms is comparable to that out of the Galactic plane and therefore suggest that this may lead to exaggerated shell expansion away from spiral arms and into interarm regions.

description: This study evaluated the impact of increased energy price on income of shallow tubewell (STW) owners under diesel and electrically operated STWs. Five adjacent villages of Ghatail Upazila in Tangail district were purposively selected. In total, 30 STW owners were randomly selected from these villages. Both diesel operated shallow tubewell (DOSTW) and electricity operated shallow tubewell (EOSTW) business were found profitable in current energy prices. The profit from MV Boro paddy production under EOSTW was relatively higher than the DOSTW due to lower operation and maintenance (0 & M) cost of EOSTW. The DOSTW owners were anxious about increased price of diesel over time. The trend of increasing diesel price hike would possibly break the existing irrigation market in Bangladesh. A stable energy price is essential to protect the irrigation water market, more particularly DOSTW. A reasonable scope apparently exists in the study areas for the expansion of STWs to increase productivity of MV Boro paddy and farm income of the STW owners. Hence, investment in this business can go ahead elsewhere in Bangladesh where topographical and ecological environments are similar to those of the study areas. Since the EOSTW business was more profitable than the DOSTW, the expansion of electricity supply to this business would be positive way to increase the food production resulting ultimate food security of farm households. It is also necessary to take steps for stabilizing diesel price for the interest of the majority of MV Boro paddy producers mainly depend on DOSTWs.
Singlet-to-triplet ratio in the deuteron breakup reaction $pd\to pnp$ at 585 MeV

description: Available experimental data on the exclusive $pd\to pnp$ reaction at 585 MeV show a narrow peak in the proton-neutron final-state interaction region. It was supposed previously, on the basis of a phenomenological analysis of the shape of this peak, that the final spin-singlet $pn$ state provided about one third of the observed cross section. By comparing the absolute value of the measured cross section with that of $pd$ elastic scattering using the Fäldt-Wilkin extrapolation theorem, it is shown here that the $pd\to pnp$ data can be explained mainly by the spin-triplet final state with a singlet admixture of a few percent. The smallness of the singlet contribution is compatible with existing $pN\to pNπ$ data and the one-pion exchange mechanism of the $pd\to pnp$ reaction.

description: The study was undertaken to evaluate the contribution of agro-industry in the Bangladesh economy. The latest two input-output tables of the year 1993-94 and 2001-2002 in Bangladesh were used to calculate inter-industry linkage indices and multiplier effects. Agroindustry contributes a significant portion of national income and the prospect of employment generation is increasing at the higher extent for the sectors food processing, tanning and leather finishing, leather industry, saw milling and wooden furniture. Food processing, fish processing, tanning and leather finishing, leather fabrication, livestock, and poultry were the key sectors of the Bangladesh economy. Input dependence of some of the agricultural production sectors were increased from early nineties to early two thousand. Tanning and leather finishing, leather processing, edible oil, food processing and paper industry draw heavily on other primary industries across a broad spectrum of supplying industries and these sectors have powerful stimulus to the economy than the other sectors. Most of the agricultural processing sectors including some agricultural production sectors have better potential to generate more income. All the agro-processing industries except edible oil generate the higher income of which tanning and leather finishing, jute bailing, rice milling and sweeteners generate high level of income. The highest employment was generated in the sector livestock followed by poultry. The agro-industries having large multiplier values were the edible oil, leather finishing, rice milling, ata and flour milling and fish processing.

description: The study estimated the rates of returns to investment on research and development of summer onion in Bangladesh. The Economic Surplus Model with ex-post analysis using secondary data was used to determine the returns to investment and its distribution between the production and consumption. Several discounting techniques were also used to assess the impact of summer onion research. The results revealed that the growth of area and production of onion increased manifolds due to farm level adoption of summer onion. The summer onion adoption rate was found increasing trend over the period. The yield of summer onion was 57.04% higher than the local variety. The internal rate of return (IRR), net present value (NPV), and benefit cost ratio (BCR) were estimated to be 25%, Tk.35.29 million and 3.09 respectively. Sensitivity analysis revealed that under various assumptions IRR ranged from 20 to 41%, NPV from Tk.18.37 to Tk.64.05 million, and BCR from 2.31 to 5.95. The results indicated that investment in research and development of summer onion was a good investment.

description: This study examines the need to introduce crop revenue insurance through analyzing its social welfare effects for the five target crops of the 2013 tabletop exercise. Based on the 5,000 simulated crop prices and revenues, producer welfare and consumer surplus resulting from the introduction of revenue insurance were estimated for each of the five crops. In addition, the cost-benefit of introducing revenue insurance was analyzed and compared with that of operating current crop yield insurance from the standpoint of the country as a whole. We found that the increase in producer and consumer welfare due to subscribing revenue insurance is 5.9 billion won and 3.0 billion won, respectively, for the five crops in total. The results of cost-benefit analysis show that net benefit of introducing revenue insurance is estimated to increase by 5.1 billion won, which is 3.4 billion won more than the net benefit increase of 1.7 billion won which could be attained through the implementation of current crop yield insurance. Although revenue insurance has many benefits, it needs to be dealt with carefully through considering various operating issues such as finding of additional data, complex evaluation of loss, and prevention of moral hazard.

description: We introduce a new color decomposition for multi-parton amplitudes in QCD, free of fundamental-representation matrices and structure constants. This decomposition has a physical interpretation in terms of the flow of color, which makes it ideal for merging with shower Monte-Carlo programs. The color-flow decomposition allows for very efficient evaluation of amplitudes with many quarks and gluons, many times faster than the standard color decomposition based on fundamental-representation matrices. This will increase the speed of event generators for multi-jet processes, which are the principal backgrounds to signals of new physics at colliders.
