Effect of climate variables on yield of major food-crops in Nepal -A time-series analysis-

Climate change influences crop yield vis-à-vis crop production to a greater extent in countries like Nepal where agriculture depends largely on natural circumstances. Plausible scenarios of climate change like higher temperatures and changes in precipitation will directly affect crop yields. Therefore, this study assesses the effect of observed climate variables on yield of major food-crops in Nepal, namely rice, wheat, maize, millet, barley and potato based on regression model for historical (1978-2008) climatic data and yield data for the food-crops. The yield growth rate of all the food-crops is positive. However, the growth rate for all crops, except potato and wheat, is below population growth rate during the period. Climate variables like temperature and precipitation are the important determinants of crop yields. Trend of precipitation is neither increasing nor decreasing significantly during this period. However, temperature is increasing by 0.7 0C during the period. Climate variables show some influences on the yield of these major food-crops in Nepal. Increase in summer rain and maximum temperature has contributed positively to rice yield. Also, increase in summer rain and minimum temperature has positive impact on potato yield. However, increase in summer rain and maximum temperature adversely affected the yield of maize and millet. Increase in wheat and barley yield is contributed by current trend of winter rain and temperature. Consideration of spatial variation in similar type of study in Nepal that will be helpful in identifying the region more vulnerable to climate change in terms of crop yield is highly recommended.
Intra-Team Strategies for Teams Negotiating Against Competitor,
  Matchers, and Conceders

Under some circumstances, a group of individuals may need to negotiate
together as a negotiation team against another party. Unlike bilateral
negotiation between two individuals, this type of negotiations entails to adopt
an intra-team strategy for negotiation teams in order to make team decisions
and accordingly negotiate with the opponent. It is crucial to be able to
negotiate successfully with heterogeneous opponents since opponents'
negotiation strategy and behavior may vary in an open environment. While one
opponent might collaborate and concede over time, another may not be inclined
to concede. This paper analyzes the performance of recently proposed intra-team
strategies for negotiation teams against different categories of opponents:
competitors, matchers, and conceders. Furthermore, it provides an extension of
the negotiation tool Genius for negotiation teams in bilateral settings.
Consequently, this work facilitates research in negotiation teams.Comment: Novel Insights in Agent-based Complex Automated Negotiation, 201
Multi-scale problems, high performance computing and hybrid numerical methods

International audienceThe turbulent transport of a passive scalar is an important and challenging problem in many applications in fluid mechanics. It involves different range of scales in the fluid and in the scalar and requires important computational resources. In this work we show how hybrid numerical methods, combining Eulerian and Lagrangian schemes, are natural tools to address this multi-scale problem. One in particular shows that in homogeneous turbulence experiments at various Schmidt numbers these methods allow to recover the theoretical predictions of universal scaling at a minimal cost. We also outline hybrid methods can take advantage of heterogeneous platforms combining CPU and GPU processors
Designer Supersurafaces via Bioinspiration and Biomimetics for Dental materials and Structures

The design of surfaces and interfaces gives rise to superior qualities and properties to materials and structures. The interface between biology and materials in nature is being closely examined at the smallest scales for a number of significant reasons. It is recognised that the properties of surfaces have definite biological effects that can be harnessed in clinical regeneration biology. Also the deeper understanding of surface interactions between cells and matrices in human biology is spurring the fabrication of biomimetic and bioinspired versions of these natural designs. The new emerging science of bioinspired surface engineering is helping to improve clinical performances for biomaterials and biostructures because it resolves the problems necessary to optimise integration of implant biomaterials and structures. One of the major developments is the use of surface topography, which is now being exploited for microbial control, steering stem cell behaviours in proliferation and differentiation and adhesive surfaces for better bonding with tissues. In this Chapter we will explore the status of these super surfaces and examine the possibilities for the next generation of dental biomaterials and implants.published_or_final_versio
Breaking so(4) symmetry without degeneracy lift

We argue that in the quantum motion of a scalar particle of mass "m" on S^3_R
perturbed by the trigonometric Scarf potential (Scarf I) with one internal
quantized dimensionless parameter, \ell, the 3D orbital angular momentum, and
another, an external scale introducing continuous parameter, B, a loss of the
geometric hyper-spherical so(4) symmetry of the free motion can occur that
leaves intact the unperturbed {\mathcal N}^2-fold degeneracy patterns, with
{\mathcal N}=(\ell +n+1) and n denoting the nodes number of the wave function.
Our point is that although the number of degenerate states for any {\mathcal N}
matches dimensionality of an irreducible so(4) representation space, the
corresponding set of wave functions do not transform irreducibly under any
so(4). Indeed, in expanding the Scarf I wave functions in the basis of properly
identified so(4) representation functions, we find power series in the
perturbation parameter, B, where 4D angular momenta K\in [\ell , {\mathcal
N}-1] contribute up to the order \left(\frac{2mR^2B}{\hbar^2}\right)^{{\mathcal
N}-1-K}. In this fashion, we work out an explicit example on a symmetry
breakdown by external scales that retains the degeneracy. The scheme extends to
so(d+2) for any d.Comment: Prepared for the proceedings of the conference "Lie Theory and Its

On Nonlocal Modified Gravity and Cosmology

Despite many nice properties and numerous achievements, general relativity is
not a complete theory. One of actual approaches towards more complete theory of
gravity is its nonlocal modification. We present here a brief review of
nonlocal gravity with its cosmological solutions. In particular, we pay special
attention to two nonlocal models and their nonsingular bounce solutions for the
cosmic scale factor.Comment: 11 pages, Published in Springer Proceedings in Mathematics &

Super-de Sitter and alternative super-Poincar\'e symmetries

It is well-known that de Sitter Lie algebra $\mathfrak{o}(1,4)$ contrary to
anti-de Sitter one $\mathfrak{o}(2,3)$ does not have a standard
$\mathbb{Z}_2$-graded superextension. We show here that the Lie algebra
$\mathfrak{o}(1,4)$ has a superextension based on the
$\mathbb{Z}_2\times\mathbb{Z}_2$-grading. Using the standard contraction
procedure for this superextension we obtain an {\it alternative}
super-Poincar\'e algebra with the $\mathbb{Z}_2\times\mathbb{Z}_2$-grading.Comment: 10 pages, X. International Workshop LIE THEORY AND ITS APPLICATIONS

Physical ageing and new representations of some Lie algebras of local
  scale-invariance

Indecomposable but reducible representations of several Lie algebras of local
scale-transformations, including the Schr\"odinger and conformal Galilean
algebras, and some of their applications in physical ageing are reviewed. The
physical requirement of the decay of co-variant two-point functions for large
distances is related to analyticity properties in the coordinates dual to the
physical masses or rapidities.Comment: Latex2e (+ macros), 17 pages with 1 figure included, proceedings

Injectivity theorems with multiplier ideal sheaves and their
  applications

The purpose of this survey is to present analytic versions of the injectivity
theorem and their applications. The proof of our injectivity theorems is based
on a combination of the L^2-method for the dbar-equation and the theory of
harmonic integrals. As applications, we obtain Nadel type vanishing theorems
and extension theorems for pluri-canonical sections of log pairs. Moreover, we
give some results on semi-ampleness related to the abundance conjecture in
birational geometry (the minimal model program).Comment: 14pages. arXiv admin note: substantial text overlap with

A coherent Ising machine for MAX-CUT problems : Performance evaluation
  against semidefinite programming relaxation and simulated annealing

Combinatorial optimization problems are computationally hard in general, but
they are ubiquitous in our modern life. A coherent Ising machine (CIM) based on
a multiple-pulse degenerate optical parametric oscillator (DOPO) is an
alternative approach to solve these problems by a specialized physical
computing system. To evaluate its potential performance, computational
experiments are performed on maximum cut (MAX-CUT) problems against traditional
algorithms such as semidefinite programming relaxation of Goemans-Williamson
and simulated annealing by Kirkpatrick, et al. The numerical results
empirically suggest that the almost constant computation time is required to
obtain the reasonably accurate solutions of MAX-CUT problems on a CIM with the
number of vertices up to $2 \times 10^4$ and the number of edges up to $10^8$.Comment: 10 pages, 9 figures; v5: typo in Table 1 (C_best of g22 is 0.9450
Large Scale 4D Trajectory Planning

International audienceTo sustain the continuously increasing air traffic demand, the future air traffic management system will rely on a so-called trajectory based operations concept that will increase air traffic capacity by reducing the controllers’ workload. This will be achieved by transferring tactical conflict detection and resolution tasks to the strategic planning phase. In this future air traffic management paradigm context, this paper presents a methodology to address such trajectory planning at nation-wide and continent scale. The pro-posed methodology aims at minimizing the global interaction between aircraft trajectories by allocating alternative departure times, alternative horizontal flight paths, and alternative  flight levels to the trajectories involved in the interaction. To improve robustness of the strategic trajectory planning, un-certainty of aircraft position and aircraft arrival time to any given position on the trajectory are considered. This paper presents a mathematical formulation of this strategic trajectory planning problem leading to a mixed-integer optimization problem, whose objective function relies on the new concept of interaction between trajectories. A computationally efficient algorithm to compute interaction between trajectories for large-scale applications is presented and implemented. Resolution method based on hybrid-metaheuristic algorithm have been developed to solve the above large-scale optimization problems. Finally, the overall methodology is implemented and tested with real air traffic data taking into account uncertainty over the French and the European airspace, involving more than 30,000 trajectories. Conflict-free and robust 4D trajectory planning are produced within computational time acceptable for the operation context, which shows the viability of the approach
On the amplitude equation of approximate surfacewaves on the plasma-vacuum interface

In this paper we present a recent result about the propagation of weakly nonlinear surface waves on a plasma-vacuum interface. In the plasma region we consider the equations of incompressible magnetohydrodynamics, while in vacuum the magnetic and electric fields are governed by the Maxwell equations. A surface wave propagate along the plasma-vacuum interface, when it is linearly weakly stable.\ud
Following the approach of Alì and Hunter, we measure the amplitude of the surface wave by the normalized displacement of the interface in a reference frame moving with the linearized phase velocity of the wave, and obtain that it satisfies an asymptotic nonlocal, Hamiltonian evolution equation with quadratic nonlinearity. We show the local-in-time existence of smooth solutions to the Cauchy problem for the amplitude equation in noncanonical variables, and we derive the regularity of the first order corrections of the asymptotic expansion
The fate of bilingualism in a model of language competition

The original publication is available at Springer website: http://www.springer.com/computer/mathematics/book/978-4-431-73150-4.In the general context of dynamics of social consensus, we study an agent based model for the competition between two socially equivalent languages, addressing the role of bilingualism and social structure. In a regular network, we study the formation of linguistic domains and their interaction across the boundaries. We analyse also a small world social structure, in order to capture the effect of long range social interactions. In both cases, a final scenario of dominance of one language and extinction of the other is obtained, but with smaller times for extinction in the latter case. In addition, we compare our results to our previous work on the agent based version of Abrams-Strogatz model.We acknowledge financial support from the MEC (Spain) through project CONOCE2 (FIS2004-00953).

The Role of Macroeconomic Fundamentals in Malaysian Post Recession Growth

This study aims to find out the role of macroeconomic fundamentals in Malaysian post recession growth. The selected macroeconomic variables are exports, imports, price level, money supply, interest rate, exchange rate and government expenditure. The technique of cointegration was employed to assess the long run equilibrium relationships among the variables. Then, this study performs the Granger causality tests based on VECM to establish the short run causality among the variables. The long-run cointegrating relationship shown that an increase in exports, government expenditure or depreciation of exchange rate will promote long-term economic growth while increase in inflation, interest rate and imports will tamper the Malaysian economic growth. The results of short-run Granger-causality indicated that price level and government spending Granger-caused economic growth in the short-run. In conclusion, based on the results of long-run and short run analysis, the fiscal policy is probably the most appropriate tool in promoting economic growth in Malaysia during the post recession period.
Hindi and English Off-line Signature Identification  and Verification

Biometric systems play a significant role in the field of information  security as they are extremely required for user authentication. Signature  identification and verification have a great importance for authentication  intention. The purpose of this paper is to present an empirical contribution  towards the understanding of multi-script (Hindi and English) signature  verification. This system will identify whether a claimed signature belongs to  the group of English signatures or Hindi signatures from a combined Hindi and  English signature datasets and then it will verify signatures using these two  resultant signature datasets (Hindi script signature and English script signatures)  separately. The modified gradient feature and SVM classifier were employed  for identification and verification purposes. To the best of authors' knowledge,  the multi-script signature identification and verification has never been used for  the task of signature verification and this is the first report of using Hindi and  English signatures in this area. Two different results for identification and  verification are calculated and analysed. The accuracy of 98.05% is obtained for  the identification of signature script using 2160 (1080 Hindi + 1080 English)  samples for training and 1080 (540 Hindi + 540 English) samples for testing.  The resultant data sets obtained in script identification of signatures were used  for verification purpose. The FRR, FAR for Hindi and English was obtained  8.0%, 4.0% and 12.0%, 10.0% respectively.Griffith Sciences, School of Information and Communication TechnologyFull Tex
Sweet Sorghum: From theory to practice

Sweet sorghum [Sorghum bicolor (L.) Moench] is a multipurpose crop (food, feed, fodder and fuel) that has the potential as an alternative biofuel feedstock without impacting food and fodder security. This chapter entitled “Sweet sorghum: From theory to practice” discusses on the historical developments in sweet sorghum and immense range of genetic variability that was available in major sorghum regions of the world. The candidate feedstock characteristic traits of sweet sorghum vis-a-vis other major biofuel feedstocks like sugarcane, corn and sugar beet were compared. Sweet sorghum fares well in many aspects as it is a C4 species with greater resilience to diverse agro-ecologies, low fertilizer and water requirement besides short lifecycle. Hence, many consider it as climate change ready crop; some consider it as miracle crop and few term it as a smart crop. A quantitative insight into the production-ecological sustainability of sweet sorghum biofuel feedstock production systems has been discussed. The ongoing R&D efforts at ICRISAT as well as in National Agricultural Research System (NARS) on sweet sorghum value chain were highlighted. The breeding efforts in Brazil, USA and China on this crop are briefly narrate
Methodology, results and discussion

There are many research and review articles published on sweet sorghum. However, no single publication gives a detailed account of the morpho-biochemical traits of improved tropical sweet sorghum cultivars. This chapter gives detailed account of the materials used, methods followed for data collection and analysis to characterise sweet sorghum genotypes following the guidelines of Protection of Plant Varieties and Farmers Rights Act, 2001 (PPVFRA). The pooled analysis of variance for quantitative traits revealed that these cultivars had significant differences between them for the expression of all the quantitative characters under study for both the seasons. The results revealed that the productivity levels of tropical sweet sorghums during post-rainy season (October–March) are generally low due to photo-sensitivity and thermo-sensitivity of the genotypes vis-a-vis that of rainy season (June–October) and necessitates identifying new sources/alleles contributing to both biomass and sugar yiel
Rainy season cultivars and hybrid parents

This chapter entitled “Rainy season cultivars and hybrid parents” gives a focussed description of improved sweet sorghum varieties/restorers, hybrids and female hybrid parents (as per PPVFRA). The coloured picture of the line is provided for easy identification. The genetic variability for all the metric traits is conspicuous and for some of the qualitative traits like anthocyanin coloration, glume color differences between the lines are not quite revealing. Among the biochemical traits such as sucrose, glucose and fructose the differences are significant among the cultivar
Commercialization: Status and way forward

Ethanol is a biofuel that is used as a fuel additive and a replacement for nearly 3 % of the world’s fossil fuel-based gasoline consumption. Currently, most of the bioethanol is produced from sugarcane in Brazil and corn in the United States, while biodiesel is made from rapeseed in Europe. The rationale for the success of the Brazilian Proalcool program, its present status and its perspectives has been presented. The Proalcool program’s mandate was a vast increase in ethanol production with a sound government-backed subsidies and incentives initially to reach the goal; however, it was the private investors and companies that were solely responsible to achieve the end result. The Proalcool program indeed provides several essential lessons to many countries around the world about the potential competitiveness of biofuels vis-à-vis traditional fuels. Considering the importance of alternate biofuels, sweet sorghum has been identified as a promising energy crop to meet the energy security and reduce the dependence on fossil fuels in many countries around the globe. The Indian National Biofuel Policy (2009) recognizes sweet sorghum as a major biofuel feedstock and well adapted to India. However, its value chain could not get popular as anticipated due to low price level (Rs. 27) fixed by Government of India. Hence, it is necessary to review the ethanol price in India so as to give fillip to the beleaguered biofuel industry, which will likely to play a stabilization role in a oil import dependent economy like ours. Similarly, a number of case studies are presented on the research efforts made in various countries around the world like India, USA, Brazil and China on the use of sweet sorghum as a potential bioenergy feedstock. The current and commercialization status of the various biofuel technologies and approaches are discussed. The biofuel blending targets and mandates of different countries are also presente
