description: We analyze, in the framework of AdS/CFT correspondence, the gauge theory phase structure that are supposed to be dual to the recently found non-supersymmetric dilatonic deformations to AdS_5 X S^5 in type IIB string theory. Analyzing the probe D7-brane dynamics in the backgrounds of our interest, which corresponds to the fundamental N=2 hypermultiplet, we show that the chiral bi-fermion condensation responsible for spontaneous chiral symmetry breaking is not logically related to the phenomenon of confinement.

description: Americans’ diets, particularly those of low-income households, fall short of Government recommendations in the quantity of fruits and vegetables consumed. Some proposals suggest that a price subsidy for those products would encourage low-income Americans to consume more of them. This study estimated that a 10-percent subsidy would encourage low-income Americans to increase their consumption of fruits by 2.1-5.2 percent and vegetables by 2.1-4.9 percent. The annual cost of such a subsidy for low-income Americans would be about $310 million for fruits and $270 million for vegetables. And most would still not meet Federal dietary recommendations.

Balanced normal cones and Fulton-MacPherson's intersection theory

description: Let X be a subscheme of a reduced scheme Y. Then Y has a flat "degeneration to the normal cone" C_X Y of X, and this degeneration plays a key step in Fulton and MacPherson's "basic construction" in intersection theory. The intersection product has a canonical refinement as a sum over the components of C_X Y, for X and Y depending on the given intersection problem. The cone C_X Y is usually not reduced, which leads to the appearance of multiplicities in intersection formulae. We describe a variant of this degeneration, due essentially to Samuel, Rees, and Nagata, in which Y flatly degenerates to the "balanced" normal cone \barC_X Y. This space is reduced, and has a natural map onto the reduction (C_X Y)_red of C_X Y. The multiplicity of a component now appears as the degree of this map. Hence intersection theory can be studied using only reduced schemes. Moreover, since the map \barC_X Y \to (C_X Y)_red may wrap multiple components of \barC_X Y around one component of C_X Y, writing the intersection product as a sum over the components of \barC_X Y gives a further canonical refinement. \\ In the case that X is a Cartier divisor in a projective scheme Y, we describe the balanced normal cone in homotopy-theoretic terms, and prove a useful upper bound on the Hilbert function of \barC_X Y.

description: We report inelastic neutron scattering measurements of the phonon spectrum of the pressure-induced ferromagnetic superconductor UGe$_{2}$. No changes of the spectrum were found on cooling down to low temperature. The phonon contribution to the specific heat was estimated from a fit to our data. The excess specific heat previously noted at around $T_{x} \approx$ 30 K is not due to phonons but is well described by the temperature dependence of the magnetic order parameter at the molecular field level.

Gravitational Brownian motion as inhomogeneous diffusion: black hole populations in globular clusters

description: Recent theoretical and numerical developments supported by observational evidence strongly suggest that many globular clusters host a black hole (BH) population in their centers. This stands in contrast to the prior long-standing belief that a BH subcluster would evaporate after undergoing core collapse and decoupling from the cluster. In this work, we propose that the inhomogeneous Brownian motion generated by fluctuations of the stellar gravitational field may act as a mechanism adding a stabilizing pressure to a BH population. We argue that the diffusion equation for Brownian motion in an inhomogeneous medium with spatially varying diffusion coefficient and temperature, which was first discovered by Van Kampen, also applies to self-gravitating systems. Applying the stationary phase space probability distribution to a single BH immersed in a Plummer globular cluster, we infer that it may wander as far as $\sim 0.05,\,0.1,\,0.5{\rm pc}$ for a mass of $m_{\rm b} \sim 10^3,\,10^2,\,10{\rm M}_\odot$, respectively. Furthermore, we find that the fluctuations of a fixed stellar mean gravitational field are sufficient to stabilize a BH population above the Spitzer instability threshold. Nevertheless, we identify an instability whose onset depends on the Spitzer parameter, $S = (M_{\rm b}/M_\star) (m_{\rm b}/m_\star)^{3/2} ,$ and parameter $B = ρ_{\rm b}(0) (4πr_c^3/M_b)(m_\star/m_{\rm b})^{3/2} $, where $ρ_{\rm b}(0)$ is the Brownian population central density. For a Plummer sphere, the instability occurs at $(B,S) = (140,0.25)$. For $B > 140,$ we get very cuspy BH subcluster profiles that are unstable with regard to the support of fluctuations alone. For $S > 0.25,$ there is no evidence of any stationary states for the BH population based on the inhomogeneous diffusion equation.

At every regular value of the moment map for X x Y, the integral is the convolution of two distributions associated to the symplectic reductions of X by T and of Y by T. Several examples illustrate the computational strength of this relationship. We also prove a linear analogue which can be used to find cohomology pairings on toric orbifolds.

description: The impact of land irrigability classes on crop productivity has been reported based on the survey of Mahi right bank (MRB), Ukai-Kakrapar right bank (UKRB) and Kakrapar left bank (KLB) canal command areas of the Gujarat state. The multi-stage random sampling method was used to select the farmers. The MRB and UKRB areas have five different soils environment in terms of land irrigability classes, while the KLB area has only three soils environment. The major crops grown in the UKRB are sugarcane, rice, cotton and pigeon pea, while sugarcane and rice are the major crops in the KLB. Similarly, in the MRB, rice, pearl millet, groundnut, wheat and tobacco crops occupy 95 per cent of the total irrigated area. The study has revealed that farmers have violated the recommended cropping pattern and are growing high water-requiring crops, irrespective of their suitability to land. In the land irrigability classes III, IV and V, cultivation of sugarcane and rice has led to waterlogging and secondary salinization problems, and reduction in crop yields. Hence, the cultivation of lower irrigability classes with minimum use of major inputs is not an advisable proposition. It would be better if crops are selected according to land irrigability classes which might result in a higher production with lower unit cost of production in the command areas under the study.

description: Catalysts’ redox reactions are crucial for storage and energy conversion. Therefore, the fabrication of cost-effective, structurally rational, and multifunctional advanced catalytic materials continues to be a crucial task. In this study, we obtained P, Fe, and Co co-doped, nitrogen-rich carbon nanofibers by directly forming carbon nanotubes from metal-organic frameworks through electrospinning and pyrolysis. The P0.025-FeCo/C catalyst demonstrated outstanding ORR activity, including an ECSA of 1954.3 cm2, a limited current density of −3.98 mA/cm2, an E1/2 of ~0.84 V, and an Eonset of ~0.94 V. After 5000 cycles, the P0.025-FeCo/C catalyst demonstrated remarkable enduring stability. These function enhancements occurred because of the electronic coupling between the metal and phosphorus, which altered the electron distribution at the metal center and optimized its electronic structure, thereby improving catalytic activity and stability. It exhibits good chemical stability in alkaline media and can maintain its catalytic performance for a long time, demonstrating good durability. Its tubular structure provides many active sites and superior electron transport paths owing to its unique channels and cavities, which help improve its activity and stability. Therefore, P0.025-FeCo/C is expected to become a non-precious metal catalyst for facilitating oxygen reduction reactions. The P0.025-FeCo/C catalyst exhibits excellent ORR activity and significant long-lasting stability. It is expected to become a non-noble metal catalyst that promotes oxygen reduction reaction.

description: We propose that the radion chiral supermultiplet of five dimensional compactified supergravity is obtained by reduction of the graviphoton gauge multiplet to N=1 superfields in the off shell 5D superconformal gravity formalism of Fujita, Kugo and Ohashi. We present a superfield Lagrangian of Chern-Simons type (similar to global SUSY), which reproduces all component couplings of gauge fields and the radion. A hypermultiplet superspace action is also proposed which correctly accounts for the coupling of matter multiplets with gauge and radion superfields. 4D supergravity enters by the coupling to the 4D Weyl multiplet, an even orbifold parity multiplet embedded in the 5D Weyl multiplet. We apply this formalism to a discussion of Fayet-Iliopolous terms, and the gauging of orbifold SUGRA to obtain warped solutions.

description: This paper presents an acoustic study of a standard NACA 0012 aerofoil with additional self-oscillating passive flaplets attached to the trailing edge. The tests with varying geometries of the flaplets were conducted in the anechoic wind tunnel at Brandenburg University of Technology, at chord based Reynolds numbers, $Re_c = 100,000 - 900,000$ at three geometric angles of attack $α_g = 0^\circ, 10^\circ$ and $15^\circ$. It was observed that all flaplet configurations reduce tonal noise and that the key geometric parameter to reduce this noise component is the width of the flaplets. The narrowest configuration tested almost completely removed the tonal noise, leading to an average overall sound pressure level reduction of up to 9 dB across the entire $Re_c$ range at $α_g = 10^\circ$. It was also observed that, in the low frequency regime, a further noise reduction can be achieved by tuning the natural frequency of the oscillating flaplets. The thereby affected frequency range in the noise spectrum moves to higher frequencies when the natural frequency of the flaplets is increased and vice versa. Hence we show a novel way to target specific frequencies in passive aerofoil self-noise cancellation.
A modified adaptive hill climbing maximum power point tracking (MPPT) control method for photovoltaic power systems
Creators: name: Xiao, Weidong
Publisher: name: University of British Columbia
Year: 2009

description: A powerful attraction of photovoltaic (PV) power systems is that they produce electric power without harming the environment, by directly transforming a free inexhaustible source of energy, solar irradiation, into electricity. This fact, together with the continuing decrease in PV array cost and increase in efficiency, implies a promising role for PV generation systems in the near future. The study started with the requirement that photovoltaic power systems should be integrated with specific control algorithms to deliver maximum possible power. In this thesis, the PV power system was introduced at the beginning, and a simple maximum power point tracking (MPPT) system was presented and analyzed. Next, different existing MPPT control approaches were discussed and a proposed control algorithm, namely modified adaptive hill climbing (MAHC) method, was introduced. Then, the results of simulation proved that the performance could be improved in both transient and steady state of the suggested control system. Finally, a simple test bed system with digital signal processor (DSP) was designed and implemented with optimized control software to verify the proposals.

description: Falling groundwater tables and depletion of economically accessible groundwater resources would have major social and economic consequences. The present study has been taken up with the overall objective of evolving optimal crop plans to sustain the use of groundwater resources for irrigation. Perambalur district was purposively selected for the study as it mainly depends on groundwater for its irrigation. Linear programming technique was used to evolve optimal crop plans. The constraints identified were primarily irrigation water, besides land availability during the cultivating seasons and capital. Six typical farms were selected, one each for the open well, wells in tank command area and tubewell-irrigated farms in critical and over-exploited groundwater regime and also for semi-critical and safe groundwater regime. The results of the optimal crop plans derived showed that the irrigation water-use in the critical period could be reduced by 24.30, 4.54 and 51.71 hours of pumping in ordinary wells, wells in tank command area and tubewell-irrigated farms, respectively in critical and over-exploited groundwater regime sample farms. In the semi-critical and safe groundwater regime sample farms, the optimal crop plans revealed that the irrigation water-use in the critical period could be reduced by 4.61, 3.99, and 4.73 hours of pumping in ordinary wells, wells in tank command area and tubewell-irrigated farms, respectively. Area under high water intensive crops namely, paddy and sugarcane declined almost in all the optimal crop plans. Area under low water intensive crops (groundnut, gingelly and tapioca) showed an increasing trend in all optimal crop plans. The net income of the sample farms increased marginally or considerably in the optimal crop plans of both the critical and overexploited groundwater regime sample farms and semi-critical and the safe groundwater regime sample farms

description: Besides the analysis of technical and ecological viability, knowledge of the existing land tenure systems is an essential pre-requisite for the success of watershed projects and policy reforms required for their effective implementation. Using descriptive analysis, Lorenz curve and Gini concentration ratio (GCR), this study has explained the relationship between the existing land tenure systems and the prospects for the success of watershed projects in the Meghalaya State, North-East India. The study has revealed that the Umsiang watershed project having community ownership system of tenure produced more positive changes in the landuse pattern after the project implementation than the Maweit watershed project practising individual ownership system. The area under jhum cultivation in the Umsiang watershed decreased significantly due to transformation of jhum sloppy lands into permanent contour cultivation. The area under horticulture plantations particularly fruit crops increased by 2118 per cent; afforested and aquaculture areas also increased by 296 and 2480 per cent, respectively after the project. The area under jhum cultivation in the Maweit watershed decreased only marginally (by 2%) and the area under permanent contour cultivation was negligible after the project. The absence of ownership rights to the tenants in the Maweit watershed has resulted in little incentive for the adoption of long-term development measures. The annual average income per household increased to Rs 40,227 (36% increase) in the Umsiang watershed and to Rs 36,313 (19% increase) in the Maweit watershed after the project. The offfarm income went up by 49 per cent in the Umsiang watershed and 38 per cent in the Maweit watershed. The watershed projects under the Community ownership system of land tenure would be more successful in increasing farm income and employment opportunities. The income inequality also decreased in the Umsiang watershed after the project as shown by Lorenz curve and GCR. But the gap between the rich and the poor in the Maweit watershed increased after the project. The study has clearly indicated that land tenure system is an important factor in the implementation of watershed projects successfully. Effective land reform policy would be essential for the successful implementation of watershed development programmes.

description: The equity issues concerning soil degradation and soil reclamation have been analysed for Tungabhadra Project Area of the Karnataka state. The study is based on primary data obtained from 325 respondent farmers. The data gathered by survey method have been analysed using conventional and simple tabular method of analysis, Gini ratio, and Lorenz curve. The study has revealed that the small and marginal farmers are worst affected by soil degradation. The large farmers have also experienced the brunt of soil degradation but the effect has been marginal since they have alternative sources of livelihood. The study has further indicated that the extent of inequity is higher on degraded than normal soils. However, this can be reduced to a great extent by launching land reclamation programmes. Therefore, the study has suggested that the government should initiate land reclamation programmes on a large scale on long-term basis so that the fruits of land reclamation technologies could reach the vulnerable sections of the society.

description: Since 2011 Ventspils International Radio Astronomy Centre has been involved in the large scale infrastructure project which allowed significant speeding-up of the upgrading activities related to radio telescopes RT-32 and RT-16 as to its fitting with appropriate VLBI receiving and recording equipment. Radio telescopes were instrumented with new state-of-art broadband cryogenic receivers for frequency range of 4.5 - 8.8 GHz developed and installed by company Tecnologias de Telecomunicaciones e Informacion. In this paper architecture of receiving system as well as significance and working principles of key subsystems are described. The receiver is formed by a cooled RF subsystem and a room temperature IF subsystem. The RF and IF subsystems are designed to process two C and X band signals (LCP and RCP) in parallel. Normally, during observations, the measured vacuum level in the receivers dewar is from 10e-6 to 10e-8 mbar and the temperature inside dewar is at level of 14 K at second stage, 20 K at polarizer and 46 K at the first stage. Since October 2015 radio telescope RT-32 with new receiver system took part in several successful international VLBI sessions. During preparation for VLBI observations preliminary aperture efficiency, system temperature and beam pattern measurements were carried out to evaluate RT-32 performance after the stations renovation that besides the receiver also included repairing of the main reflector. Performance parameters were derived with the help of switching noise diode and on-off observations of calibration sources with known flux density at various elevations. First results measured at 4836 MHz are summarized in this manuscript.

description: Magnetic Compton scattering, x-ray magnetic circular dichroism spectroscopy and bulk magnetometry measurements are performed on a set of medium (NiFeCo and NiFeCoCr) and high (NiFeCoCrPd and NiFeCoCrMn) entropy Cantor-Wu alloys. The bulk spin momentum densities determined by magnetic Compton scattering are remarkably isotropic, and this is a consequence of the smearing of the electronic structure by disorder scattering of the electron quasiparticles. Non-zero x-ray magnetic circular dichroism signals are observed for every element in every alloy indicating differences in the populations of the majority and minority spin states implying finite magnetic moments. When Cr is included in the solid solution, the Cr spin moment is unambiguously antiparallel to the total magnetic moment, while a vanishingly small magnetic moment is observed for Mn, despite calculations indicating a large moment. Some significant discrepancies are observed between the experimental bulk and surface magnetic moments. Despite the lack of quantitative agreement, the element specific surface magnetic moments seem to be qualitatively reasonable.

description: Irrigation is a vital ingredient in the modern agriculture, groundwater development through modern water extraction mechanisms (WEMs) have therefore, been receiving greater emphasis in recent past. However, the ownership of private WEMs is confined mostly to the large farmers. The small and marginal farmers and even large farmers with fragmented holdings are buyers of irrigation water from the neighbouring WEM-owners. This has led to spontaneous emergence of groundwater markets. Although the water markets benefit both buyers and sellers in one or the other way, they have created certain implications in the utilization of this resource. The present study has examined the structure, determinants and efficiency of groundwater markets and has suggested policy options for the realization of equitable benefits from this resource in Western Uttar Pradesh. It is observed that a large proportion (82 %) of the farm holdings enter into one or the other form of water market activities. The number of buyers decreases as the farm-size increases, while the number of sellers increased with the increase in the size of farm. The buying of groundwater is favoured by the farmers with small size and fragmented holdings, low education attainment and less probability of joint-ownership of a WEM. The possibility has been shown of increasing the productivity in major crops like sugarcane and wheat by reducing the excessive water-use on self-users farms, which in turn would increase the availability of water on the buyers’ farms. The study has identified various policy options which would lead to minimizing the inequitable distribution of benefits and improving the efficiency of water-use under the prevailing groundwater markets system.

description: Quantum effects such as the environment assisted quantum transport (ENAQT) displayed in photosynthetic Fenna-Mathews-Olson (FMO) complex has been simulated on analog quantum simulators. Digital quantum simulations offer greater universality and flexibility over analog simulations. However, digital quantum simulations of open quantum systems face a theoretical challenge; one does not know the solutions of the continuous time master equation for developing quantum gate operators. We give a theoretical framework for digital quantum simulation of ENAQT by introducing new quantum evolution operators. We develop the dynamical equation for the operators and prove that it is an analytical solution of the master equation. As an example, using the dynamical equations, we simulate the FMO complex in the digital setting, reproducing theoretical and experimental evidence of the dynamics. The framework gives an optimal method for {quantum circuit} implementation, giving a log reduction in complexity over known methods. The generic framework can be extrapolated to study other open quantum systems.

description: Non-local properties of symmetric two-qubit states are quantified in terms of a complete set of entanglement invariants. We prove that negative values of some of the invariants are signatures of quantum entanglement. This leads us to identify sufficient conditions for non-separability in terms of entanglement invariants. Non-local properties of two-qubit states extracted from (i) Dicke state (ii) state generated by one-axis twisting Hamiltonian, and (iii) one-dimensional Ising chain with nearest neighbour interaction are analyzed in terms of the invariants characterizing them.

description: We discuss the electron spin resonance in two-dimensional electron gas at zero external magnetic field. This spin-resonance is due to the transitions between the electron states, which are split by the spin-orbit (SO) interaction, and is termed as the chiral spin resonance (CSR). It can be excited by the in-plane component of the electric field of microwave radiation. We show that there exists an inherent relationship between the spin-Hall conductivity and the CSR in a system with the SO interaction. Since in the presence of the SO interaction spin is not conserved, the electron-electron interaction renormalizes the spin-Hall conductivity as well as the frequency of the CSR. The effects of the electron interaction in systems with the SO interaction are analyzed both phenomenologically and microscopically.

description: The diffusion of elements is a key process in understanding the unusual surface composition of white dwarfs stars and their spectral evolution. The diffusion coefficients of Paquette et al. (1986) have been widely used to model diffusion in white dwarfs. We perform new calculations of the coefficients of inter-diffusion and ionic thermal diffusion with 1) a more advanced model that uses a recent modification of the calculation of the collision integrals that is more suitable for the partially ionized, partially degenerate and moderately coupled plasma, and 2) classical molecular dynamics. The coefficients are evaluated for silicon and calcium in white dwarf envelopes of hydrogen and helium. A comparison of our results with Paquette et al. shows that the latter systematically underestimates the coefficient of inter-diffusion yet provides reliable estimates for the relatively weakly coupled plasmas found in nearly all types of stars as well as in white dwarfs with hydrogen envelopes. In white dwarfs with cool helium envelopes (Teff < 15000K), the difference grows to more than a factor of two. We also explored the effect of the ionization model used to determine the charges of the ions and found that it can be a substantial source of discrepancy between different calculations. Finally, we consider the relative diffusion time scales of Si and Ca in the context of the pollution of white dwarf photospheres by accreted planetesimals and find factor of > 3 differences between calculations based on Paquette et al. and our model.

Publisher: name: Zenodo
Year: 2023

description: The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase 2 upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). The addition of the MIP timing detector (MTD) to CMS will be critical to mitigate the impact of high pileup collisions anticipated during the HL-LHC. The MTD will provide timing information at an unprecedented precision level. The endcap part of MTD, Endcap Timing Layer (ETL), will depend on a new Silicon based technology, Low Gain Avalanche Diodes (LGADs), as well as a specially design ASIC to readout and digitize the LGAD signal. As part of the LGAD sensor market survey for the CMS ETL detector, a radiation tolerance study of LGADs irradiated with neutrons manufactured by FBK and IMB-CNM up to a fluence of 1.5e15 n_eq/cm^2 is performed. The dependence of the collected charge, jitter and timing resolution on fluence is determined using a radioactive source and a TCT setup. The dependence of the capacitive cross-talk with the fluence at electrodes adjacent to the collector electrode is also shown.

description: The possibility that the universe may have a fundamental and positive cosmological constant has motivated an interesting cosmological model, in which initially the universe is in a cosmological constant sea, then the local quantum fluctuations violating the null energy condition create some islands with matter and radiation, which under certain conditions might corresponds to our observable universe. We in this note study the perturbation spectra of scalar fields not affecting the evolution of background during the fluctuation. We will examine whether they can be interesting, and responsible for the structure formation of observable universe.

description: The entanglement of two qubits, each defined as an effective two-level, spin 1/2 system, is investigated for the case that the qubits interact via a Heisenberg XY interaction and are subject to decoherence due to population relaxation and thermal effects. For zero temperature, the time dependent concurrence is studied analytically and numerically for some typical initial states, including a separable (unentangled) initial state. An analytical formula for non-zero steady state concurrence is found for any initial state, and optimal parameter values for maximizing steady state concurrence are given. The steady state concurrence is found analytically to remain non-zero for low, finite temperatures. We also identify the contributions of global and local coherence to the steady state entanglement.

description: The farming systems in the water-scarce region of semiarid Uttar Pradesh have been examined. The availability of land and also of water has become the most limiting factors in farming for increasing the levels of farm income and employment. Therefore, an effort has been made to suggest sustainable farming systems through optimization of farm resources and also by putting restriction on the availability of irrigation water. It has been shown that the income and employment could be increased in the water-scarce situation if the farm resources are utilized optimally and less water-requiring crops/ activities are selected in the farm plan.
