Rising demand for livestock products in India: nature, patterns and implications

With a large population and recent growth in consumer income, India’s demand for food has increased. However, research continues to emphasise basic foods, and the demand for livestock products remains poorly understood. This study examines the demand for livestock products by Indian consumers using national sample survey data. The study shows that there has been a rapid rise in the demand for livestock products in India. Within the livestock products group, milk and milk products hold the dominant share. Our analysis further suggests that India’s rapid rise in the demand for livestock products may far outpace its domestic supply. Implications are discussed.livestock products, demand and supply, India, trade implications, Agribusiness, Demand and Price Analysis, Farm Management, Food Consumption/Nutrition/Food Safety, Food Security and Poverty, Livestock Production/Industries, Production Economics,

Scale Invariance vs. Conformal Invariance: Holographic Two-Point Functions in Horndeski Gravity

We consider Einstein-Horndeski gravity with a negative bare constant as a holographic model to investigate whether a scale invariant quantum field theory can exist without the full conformal invariance. Einstein-Horndeski gravity can admit two different AdS vacua. One is conformal, and the holographic two-point functions of the boundary energy-momentum tensor are the same as the ones obtained in Einstein gravity. The other AdS vacuum, which arises at some critical point of the coupling constants, preserves the scale invariance but not the special conformal invariance due to the logarithmic radial dependence of the Horndeski scalar. In addition to the transverse and traceless graviton modes, the theory admits an additional trace/scalar mode in the scale invariant vacuum. We obtain the two-point functions of the corresponding boundary operators. We find that the trace/scalar mode gives rise to an non-vanishing two-point function, which distinguishes the scale invariant theory from the conformal theory. The two-point function vanishes in $d=2$, where the full conformal symmetry is restored. Our results indicate the strongly coupled scale invariant unitary quantum field theory may exist in $d\ge 3$ without the full conformal symmetry. The operator that is dual to the bulk trace/scalar mode however violates the dominant energy condition.Comment: Latex, 28 pages, comments and references adde

High Volumetric Performance Supercapacitors with Controlled Nanomorphology

Supercapacitor is one of the promising energy storage devices due to its relatively higher energy density compared with dielectric capacitor and higher power density and longer cycle life time (>millions) than conventional battery. In order to satisfy various requirements for energy technologies, supercapacitors with higher energy and power densities are required. In this chapter, we improved the electrochemical performance largely compared with commercial product through controlling the nanomorphology of cells. Meanwhile, although many past research programs have focused mainly on gravimetric energy densities, here we have also devoted efforts to study and develop nanomorphologic structures to realize high volumetric energy and power densities, since device volume is another critical and key performance parameter. Moreover, fundamental studies have been carried out on the mobile ion transport and storage in the nanostructures developed in this chapter

Optimal teleportation via thermal entangled states of a two-qubit Heisenberg Chain

We study the optimal teleportation based on Bell measurements via the thermal states of a two-qubit Heisenberg XXX chain in the presence of Dzyaloshinsky-Moriya (DM) anisotropic antisymmetric interaction and obtain the optimal unitary transformation. The explicit expressions of the output state and the teleportation fidelity are presented and compared with those of the standard protocol. It is shown that in this protocol the teleportation fidelity is always larger and unit fidelity is achieved at zero temperature. The DM interaction can enhance the teleportation fidelity at finite temperatures, as opposed to the effect of the interaction in the standard protocol. Cases with other types of anisotropies are also discussed.Comment: Accepted by EP

Linear active disturbance rejection control of waste heat recovery systems with organic Rankine cycles

In this paper, a linear active disturbance rejection controller is proposed for a waste heat recovery system using an organic Rankine cycle process, whose model is obtained by applying the system identification technique. The disturbances imposed on the waste heat recovery system are estimated through an extended linear state observer and then compensated by a linear feedback control strategy. The proposed control strategy is applied to a 100 kW waste heat recovery system to handle the power demand variations of grid and process disturbances. The effectiveness of this controller is verified via a simulation study, and the results demonstrate that the proposed strategy can provide satisfactory tracking performance and disturbance rejection

Food Insecurity in Asia: Why Institutions Matter

Achieving food security is of utter importance in any nation. However, food insecurity still exists in many developing countries, with Asia home to almost 65%of the world’s undernourished. This calls for urgent action. Studies that examine differences in food security performance among Asian countries are sparse. This book fills this gap by providing cross-country comparative perspectives on food security improvements. Such a study can be valuable for Asian countries to learn from each other. Country studies included in this book are Bangladesh, the People’s Republic of China, Indonesia, Israel, Japan, the Democratic People’s Republic of Korea, the Republic of Korea, Pakistan, and Singapore. These countries share similarities but also differ in terms of their institutional settings, natural resource endowments, population size, and level of economic development. This study concludes that institutional differences are the most fundamental determinants of divergent food security status. This book will be useful reading for anyone who is interested in food security of individual Asian nations and Asia as a whole, including officials of national governments and international bodies, researchers, and university students
