description: This report on Pakistan is one of a series of country studies undertaken by the International Trade and Food Security Program are IFPRI on trade and macroeconomic policies. Other studies in this series include research reports on Colombia, Argentina, Nigeria, Zaire, and the Philippines, and collaborative work with the World Bank on this tonic in several other countries in Asia, Africa, and Latin America. The findings from this research have vividly shown the need to analyze the effects of policy interventions in agriculture in developing countries in an economic-wide framework. There is now an overwhelming body of evidence showing that trade and exchange rate policies have, in most countries, had a far greater impact, generally adverse, on agricultural incentives than policies that are specific to agriculture. Through their influence on incentives vis-à-vis the nonfarm sector, these indirect and usually implicit price interventions influence private investment and labor employment in agriculture and induce substantial income transfers from agriculture to the rest of the economy. This research report examines the Pakistan experience from the early 1960s until 1987. it attempts to quantify the effects on the agricultural sector of both sectoral policy interventions and the indirect effect of economy-wide trade and macroeconomic policies. The empirical findings are analyzed in a broad policy context, and the authors draw some implications for development in Pakistan.
J/psi Production and Nuclear Effects for d+Au and p+p Collisions at sqrt(s_NN) = 200 GeV

description: J/psi production in d+Au and p+p collisions at sqrt(s_NN) = 200 GeV has been measured by the PHENIX experiment at rapidities -2.2 < y < +2.4. The cross sections and nuclear dependence of J/ψproduction versus rapidity, transverse momentum, and centrality are obtained and compared to lower energy p+A results and to theoretical models. The observed nuclear dependence in d+Au collisions is found to be modest, suggesting that the absorption in the final state is weak and the shadowing of the gluon distributions is small and consistent with Dokshitzer-Gribov-Lipatov-Altarelli-Parisi-based parameterizations that fit deep-inelastic scattering and Drell-Yan data at lower energies.

description: We study the quantization of the motion of a charged particle without spin inside a flat box under a static electromagnetic field. Contrary to Landau's solution with constant magnetic field transverse to the box, we found a non separable variables solution for the wave function, and this fact remains when static electric field is added. However, the Landau's Levels appear in all cases.

description: This research report is part of IFPRI's continuous efforts to understand the relationship between technological change in agriculture and overall economic growth that expands employment and income opportunities for the poor in developing countries. The research is a collaborative effort with the Centre for the Study of Regional Development at Jawaharlal Nehru University in New Delhi. The study documents and analyzes the structural changes that have occurred in the Punjab economy since the green revolution of the mid-1960s. With two input-output tables—one for 1969/70 and the other for 1979/80—the authors have traced the sources of structural changes and examined the changes in the intersectoral linkages and the quantum of indirect and induced income and employment generated by different sectors. Thus the study provides information and critical understanding required to develop programs that enhance the sectoral income and employment multipliers. The study highlights changes in the relative importance of the primary, secondary, and tertiary sectors in the economy of Punjab in the wake of improvements in agricultural production technology. It also brings out significant structural changes within these sectors. For instance, within the primary sector, the relative share of crop production has declined, whereas that of animal husbandry has increased. Similarly, within manufacturing a notable change has been the emergence of machine- and metal-based industries. These changes are reflected in the operation of the economy at a higher technological level and in the increased labor productivity in most sectors. Pointing to the large public investment in rural infrastructure that both preceded and followed the introduction of the new agricultural technology, the authors conclude that while the primary importance of agricultural development cannot be denied, its success is by no means independent of other factors. It is notable that the agricultural breakthroughs in Punjab stimulated growth in other sectors of the economy, but not as much as had resulted from similar breakthroughs in other regions or countries, perhaps because of the large net outflow of capital from Punjab. This observation raises important issues on the role of further agricultural growth as well as the problem of interregional disparities and how best to deal with them.

description: Studies of the 16O(9Be,alpha 7Be)14C, 7Li(9Be,alpha 7Li)5He and 7Li(9Be,alpha alpha t)5He reactions at E(beam)=70 and 55 MeV have been performed using resonant particle spectroscopy techniques. The 11C excited states decaying into alpha+7Be(gs) are observed between 8.5 and 13.5 MeV. The alpha+7Li(gs), alpha+7Li*(4.652 MeV) and t+8Be(gs) decays of 11B excited states between 9 and 19 MeV are observed. The decay processes are used to indicate the possible three-centre 2alpha+3He (2alpha+3H) cluster structure of observed states. This cluster structure is more prominent in the positive-parity states, where two rotational bands with large deformations are suggested. Excitations of some of the observed T=1/2 resonances coincide with the energies of previously measured T=3/2 isobaric analogs of the 11Be states,indicating that these states may have mixed isospin.

Robust performance benchmarking : an application of multivariate and data envelopment analysis at the Workers’ Compensation Board
Creators: name: Tang, Kevin Berenato
Publisher: name: University of British Columbia
Year: 2009

description: Compensation Services manages return to work, wage loss, pension and health-care benefits to injured workers, and those suffering from occupational diseases. This thesis presents the methodology and results of a comprehensive study conducted to determine the relationships between existing performance measures, quantify the factors influencing these performance measures, and deterrriine relative efficiencies across case management operations. We use principal components analysis, cluster analysis, and multiple regression to derive the relationships between performance outcomes and influencing factors. We then use data envelopment analysis, incorporating these multiple inputs and outputs, to assess overall relative efficiencies and set performance targets. The analysis has brought about an increased understanding of service delivery location performance and performance measurement. Results may be used to provide managerial decision support, communicate best practices, and serve as a basis for further efficiency or quality initiatives. The factors accounted for in the multivariate analysis can explain between 20% - 50% of the variability in key performance outcomes across case management desks. The overall efficiency analysis revealed strong performers both within case management offices and across regions. Four case management offices consistently contain strongperforming case management desks across several methods of evaluating efficiency. Transferring best practices has the potential to significantly increase relative efficiency improvements for case management desks across the province.

You Can't Get There From Here: Hubble Relaxation in the Local Volume
Creators: name: Whiting, Alan B.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A beginning end-point for galaxy motions within the 10-Mpc Local Volume is constructed by requiring a smooth distribution of (luminous) mass at the time of recombination, which is shown to be equivalent to a smooth Hubble flow at early times. It is found, by this purely kinematical method, that present peculiar motions are too small by a factor of at least several (and largely in the wrong direction) to have produced the observed structures within the age of the universe. Known dynamical effects are inadequate to remove the discrepancy. This result is different in origin from previously known ``cold flow'' problems. The simple dynamical picture often used within the Local Volume (for instance, in deriving masses through calculation of a zero-velocity surface) is thus called into question. The most straightforward explanation (though not the only possible) is that there exists a large quantity of baryonic matter in this region so far undetected, and unassociated with galaxies or groups.

description: Mountainous regions are conspicuous due to their inimitable natural features. Natural regions are becoming progressively pretentious owing to the temperature variability pattern. Assessing temperature variability is vital to comprehend the physiography of these regions. Upper Teesta basin portrays a unique blend of a sub-tropical climate in the south and tundra type in the north. The Teesta river is considered as the lifeline of Sikkim, lies in the tundra type of climate covering the northern portion, where at least three months (November–January) of a year remain under deep snow and temperature hovering around 0 °C. The upper Teesta river basin covers the whole part of Sikkim scheming the lifestyle and occupation of the people based on the availability of its waters. Atmospheric temperature plays a crucial role in determining stream properties and water volume. Mean monthly temperature data acquired from India Meteorological Department as well as The National Centre for Environmental Prediction (NCEP) have been analysed with the help of kurtosis, skewness, and visualization done through Z-distribution in GIS environment. It provides a strategic outlook towards the proper utilization of the river water despite maintaining harmony with the climate of the region. The result depicts changes in the river itinerary concerning climatic variability pattern that calls for sustainable management of this water resource.

description: The bottom-charmed meson spectrum is studied in this work via an effective version of the Coulomb gauge QCD Hamiltonian. The Tamm-Dancoff approximation is employed to estimate the energies of the low-lying and radial-excited $B_c$ states with quantum numbers $J^P = 0^{-}, 0^{+}, 1^{-}, 1^{+}, 2^{+}, 2^{-}$. In particular, we analyze the effects of incorporating an effective transverse hyperfine interaction and spin mixing. The Regge trajectories and hyperfine splitting of both $S$- and $P$-wave states are also examined. The numerical results are compared with available experimental data and theoretical predictions of other models.

description: An antiferromagnetic domain wall in a thermal gradient is found to experience a force towards colder regions upon the application of a uniform magnetic field along the easy axis. This force increases with the strength of the applied field and, for sufficiently high values, it overcomes the entropic force the that pushes wall towards the hotter regions. The force is proportional to the thermal gradient and it shows a linear dependence with the net magnetic moment of the domain wall induced by the field. The origin of this force lies on the increase of the domain wall reflectivity due the field-induced sizable break of antiferromagnetic order inside it, which turns it into an efficient barrier for magnons, which transfer linear momentum to the domain wall when they are reflected on it

description: Over the past several years IFPRI has undertaken research on the production, consumption, and nutrition effects of agricultural commercialization in The Gambia, Guatemala, Kenya, the Philippines, and Rwanda. While it is widely recognized that the commercialization of agriculture is essential to overall economic development, various rural population groups adapt differently to the process of commercialization, depending on the resources available to them, economic and social conditions, and government policies. Many households benefit in the form of higher incomes; others may suffer a decline in income. A particular concern of policymakers has been the effect of commercialization on nutrition. The purpose of these studies has been to analyze the process of commercialization in order to identify key factors that determine nutritional outcomes, with the objective of formulating policies to enhance the beneficial effects of commercialization and minimize the harmful effects. The present report by Howarth E. Bouis and Lawrence J. Haddad presents the findings for the Philippine case study, located in an area on the southern island of Mindanao where a substantial number of households converted lands from corn to sugarcane production after construction of a sugar mill. The main effects of the introduction of export cropping in this area were a significant deterioration in access to land as smallholder corn tenant farms using primarily family labor were consolidated into larger sugar farms using primarily hired labor; an increase in incomes for households that grew sugarcane; a decline in women's participation in own-farm production; and very little improvement in nutritional status as a result of increased incomes from sugarcane production, primarily because of the high levels of preschooler sickness in the sugarcane-growing households. The difficulty of generalizing as to the varied effects of agricultural commercialization is brought out by a comparison with the case study for Kenya (see IFPRI Research Report 63 by Eileen Kennedy and Bruce Cogill), where farmers also switched from maize to sugarcane production. In that African setting, where land is often relatively abundant and labor scarce compared with many situations in Asia, women increased their participation in own-farm production as sugarcane was introduced. Yet there are important similarities as well. As all of the commercialization studies have confirmed, poor health and sanitation conditions are a serious constraint to the improved nutrition that increases in income might otherwise have made possible.

description: Morphometric parameters are usually prerequisites for the assessment of hydrological facets of a basin. Quantitative evaluation of a drainage basin further helps in the micro-level study of its physiographic characteristics. In this study, an attempt has been made to determine the detailed aspects of morphometric characteristics of the Madhyamaheshwar River basin, a watershed of the Mandakini River that constitutes a part of the Alaknanda River. There are a large number of drainage systems which have their source in the Himalaya. This study was performed using the hydrology tool in geographic information system (GIS) environment. Evaluation of linear, aerial, and relief morphometric parameters was achieved through digital delineation and drainage analysis to provide hydrological insights. A detailed morphometric analysis obtained in this study enlightens distinctive morphometric settings of stream within the drainage system like stream behaviour, the interrelation between connected streams, system’s inputs and outputs of matter, and energy. The geometric structure of the basin is ideal for flood velocity assessment backing significantly to stream energy and erosive patterns. Such geometric forms are ideal for increasing flood velocities, which contribute greatly to the available stream energy, and erosion and transportation capacities. Features such as hydrogeology have been evaluated to anticipate the drainage characteristics of the river. This study is also vital regarding the understandings of the subsurface lithology of the basin and sustainable management of the river resources.

description: The linear equations for transverse spin dynamics in a weakly polarized degenerate Fermi liquid with arbitrary relationship between temperature and polarization are derived from Landau-Silin phenomenological kinetic equation with general form of two-particle collision integral. Unlike the previous treatment where Fermi velocity and density of states have been taken as constants independent of polarization here we made derivation free from this assumption. The obtained equations are applicable for description of spin dynamics in paramagnetic Fermi liquid with finite polarization as well in an itinerant ferromagnet. In both cases transverse spin wave frequency is found to be proportional to the square of the wave vector with complex constant of proportionality (diffusion coefficient) such that the damping has a finite value at T=0. The polarization dependence of the diffusion coefficient is found to be different for a polarized Fermi liquid and for an itinerant ferromagnet. These conclusions are confirmed by derivation of transverse spin wave dispersion law in frame of field theoretical methods from the integral equation for the vortex function. It is shown that similar derivation taking into consideration the divergency of static transverse susceptibility also leads to the same attenuating spin wave spectrum.

description: ‘Water’ always has been a key resource for humankind but over the period with increasing population and rapid urbanization, water resource is under immense pressure. Groundwater is the prime source of drinking water and needs proper monitoring in order to have an optimum utilization strategy owing to the current scenario of over-exploitation. Being the part of Deccan trap region, the basin is hot and semi-arid, experiencing moderately dry climate accompanied by episodic drought and erratic showers therefore, the surface water of the basin is ephemeral. In the present study, the probabilistic recharge zones have been delineated by dint of various thematic layers viz. geological setting, geomorphic features, land use, slope gradient, infiltration number, soil physiognomies, curvature and lineament through multi-criteria decision analysis technique in the GIS domain. This has further divided into four categories, viz., very poor, poor, good, and very good zones. Thus, this paper is an attempt to demarcate probabilistic groundwater zones in the Vaniar watershed region using geospatial techniques for better planning and management of groundwater resources.

description: In this review, the general mechanism of anti-tubulin agents has been summarized used for cancer treatment. Cancer is one of the most problematic ailments that do not have an ideal cure till date, but several phytoconstituents are found to be promising for the treatment of cancer by interfering with the normal cell cycle/mitosis in the cancerous cells. The plant having tubulin inhibiting properties are discussed and their binding domains are presented. The mechanism of action is based on destabilizing the tubulin protein which is important for the cell cycle. Plants from diverse sources were found to be effective in arresting the cell cycle and hence limiting the cancer growth with the least possible adverse effects.

description: We demonstrate a cryogenic buffer gas-cooled molecular beam source capable of producing bright, continuous beams of cold and slow free radicals via laser ablation over durations of up to 60~seconds. The source design uses a closed liquid helium reservoir as a large thermal mass to minimize heating and ensure reproducible beam properties during operation. Under typical conditions, the source produces beams of our test species SrF, containing $5\times10^{12}~$molecules per steradian per second in the $X^{2}Σ(v=0, N=1)$ state with a rotational temperature of $1.0(2)~$K and a forward velocity of $140~$m/s. The beam properties are robust and unchanged for multiple cell geometries but depend critically on the helium buffer gas flow rate, which must be $\geq10~$ standard cubic centimeters per minute to produce bright, continuous beams of molecules for an ablation repetition rate of $55~$Hz.

description: We report on the first multi-epoch, phase referenced VLBI observations of the water maser emission in a high-mass protostar associated with a disk-jet system. The source under study, IRAS 20126+4104, has been extensively investigated in a large variety of tracers, including water maser VLBA data acquired by us three years before the present observations. The new findings fully confirm the interpretation proposed in our previous study, namely that the maser spots are expanding from a common origin coincident with the protostar. We also demonstrate that the observed 3-D velocities of the maser spots can be fitted with a model assuming that the spots are moving along the surface of a conical jet, with speed increasing for increasing distance from the cone vertex. We also present the results of single-dish monitoring of the water maser spectra in IRAS 20126+4104. These reveal that the peak velocity of some maser lines decreases linearly with time. We speculate that such a deceleration could be due to braking of the shocks from which the maser emission originates, due to mass loading at the shock front or dissipation of the shock energy.

De-Entanglement: A Framework towards building Ubiquitous speech technologies
Creators: name: Rallabandi, Sai Krishna
Publisher: name: Carnegie Mellon University
Year: 2024
Subjects: Ubiquitous Computing

description:

 Speech driven devices and interfaces like Apple Home pod, Google Home, Amazon Echo are increasingly becoming ubiquitous and have tremendous potential to affect our daily lives. However, deep learning models underlying these applications have yet unaddressed challenges like scalability, explainability and concerns like privacy and security. 
In my dissertation I propose a framework called De-Entanglement that has linguistic concepts as first class objects. De-Entanglement attempts to build speech technology using two core concepts referred to as content and style. Specifically, content encompasses acoustic phonetic information while style encompasses paralinguistic information from the raw audio. In my dissertation I provide experiments that show how De-Entanglement can address three challenges in a holistic fashion: 
  (1) Scalability: How to build speech technologies for new languages / language phenomena such as code switching? I demonstrate how De-Entanglement helps build more natural Text to Speech (TTS) voices. This part of the work has been deployed in the form of Android application in 13 Indian languages and has been assisting people since 2016.  (2) Flexibility: How to build models that can be manipulated to accomplish a vari?ety of functionality such as finetuning, meta learning, augmentation and self training? I present experiments in two types of models. In the context of generative models, I present an approach to show that De-Entanglement allows explicit global and local control of synthetic voices. In the context of discriminative models, I present approaches that leverage style information to detect para-linguistic events from a speech utterance.  (3) Explainability: How to build technology that is reasonable to the stakeholders? I posit that explainable speech technologies should be characterized by two properties: (a) Reasonable Understanding of internal mechanisms in the model and (b) Demonstrable Utility of the model for downstream applications. Using language identification and intent recognition from acoustics as the target applications, I demonstrate (a) how suitable priors can be incorporated into a model and (b) how such an approach leads to strong performance in low and under resourced scenarios.   
Since these linguistic constructs(concepts) are shared across different tasks within and beyond speech processing, the solutions designed using De-Entanglement hold promise to be applicable across different tasks. I present experiments to this end in both speech processing as well as broader Natural Language Processing.

description: For hexagonal nets, descriptive of {111} fcc surfaces, we derive from combinatoric arguments a simple, low-temperature formula for the orientation dependence of the surface step line tension and stiffness, as well as the leading correction, based on the Ising model with nearest-neighbor (NN) interactions. Our formula agrees well with experimental data for both Ag and Cu{111} surfaces, indicating that NN-interactions alone can account for the data in these cases (in contrast to results for Cu{001}). Experimentally significant corollaries of the low-temperature derivation show that the step line tension cannot be extracted from the stiffness and that with plausible assumptions the low-temperature stiffness should have 6-fold symmetry, in contrast to the 3-fold symmetry of the crystal shape. We examine Zia's exact implicit solution in detail, using numerical methods for general orientations and deriving many analytic results including explicit solutions in the two high-symmetry directions. From these exact results we rederive our simple result and explore subtle behavior near close-packed directions. To account for the 3-fold symmetry in a lattice gas model, we invoke a novel orientation-dependent trio interaction and examine its consequences.

description: We present an effective-Lagrangian description for forward-angle K+ Lambda photoproduction from the proton, valid for photon lab energies from threshold up to 16 GeV. The high-energy part of the amplitude is modeled in terms of t-channel Regge-trajectory exchange. The sensitivity of the calculated observables to the Regge-trajectory phase is investigated in detail. The model is extended towards the resonance region by adding a number of s-channel resonances to the t-channel background. The proposed hybrid ``Regge-plus-resonance'' (RPR) approach allows one to exploit the p(gamma,K+)Lambda data in their entirety, resulting in stronger constraints on both the background and resonance couplings. The high-energy data can be used to fix the background contributions, leaving the resonance couplings as the sole free parameters in the resonance region. We compare various implementations of the RPR model, and explore to what extent the description of the data can be improved by introducing the ``new'' resonances D13(1900) and P11(1900). Despite its limited number of free parameters, the proposed RPR approach provides an efficient description of the p(gamma,K+)Lambda dynamics in and beyond the resonance region.

description: When atoms or molecules are exposed to strong short-pulse infrared radiation, ionization as well as "frustrated tunneling ionization" (FTI) can occur, in which a portion of the almost ionized electrons recombine into the initial ground or an excited bound state. We analyze the ellipticity dependence of the relative signals that are predicted in a single-active electron approximation (SAE), the validity of which is checked against a parameter-free multi-electron \hbox{$R$-matrix} (close-coupling) with time dependence approach. We find good agreement between the results from both models, thereby providing confidence in the SAE model potential to treat the process of interest. Comparison of the relative excitation probabilities found in our numerical calculations with the predictions of Landsman {\it et al.}\ (New Journal of Physics {\bf 15} (2013) 013001) and Zhao {\it et al.}\ (Optics Express {\bf 27} (2019) 21689) reveals good agreement with the former for short pulses. For longer pulses, the ellipticity dependence becomes wider than that obtained from the Landsman {\it et al.} formula, but we do not obtain the increase compared to linearly polarized radiation predicted by Zhao {\it et al.}

description: My thesis is represented through a variety of pieces, which I feel represent the vastness of the trumpet repertoire. I have performed pieces from each of the major eras in music history: Baroque, Classical, Romantic, and Twentieth Century. As well, I have performed with a variety of different ensembles: trumpet with piano accompaniment; trumpet with organ accompaniment; trumpet and soprano duet with piano accompaniment; solo trumpet with brass choir accompaniment; and brass quintet. I also incorporated many different types of trumpets into my playing, Bb trumpet, piccolo trumpet and Eb trumpet. I feel that this choice of repertoire portrays the versatility, and demands the dedication required of being a trumpet player in this day and age.
Quantum entanglement dynamics and decoherence wave in spin chains at finite temperatures

description: We analyze the quantum entanglement at the equilibrium in a class of exactly solvable one-dimensional spin models at finite temperatures and identify a region where the quantum fluctuations determine the behavior of the system. We probe the response of the system in this region by studying the spin dynamics after projective measurement of one local spin which leads to the appearance of the ``decoherence wave''. We investigate time-dependent spin correlation functions, the entanglement dynamics, and the fidelity of the quantum information transfer after the measurement.

description: The outstanding optoelectronic and valleytronic properties of transition metal dichalcogenides (TMDs) have triggered intense research efforts by the scientific community. An alternative to induce long-range ferromagnetism (FM) in TMDs is by introducing magnetic dopants to form a dilute magnetic semiconductor. Enhancing ferromagnetism in these semiconductors not only represents a key step towards modern TMD-based spintronics, but also enables exploration of new and exciting dimensionality-driven magnetic phenomena. To this end, we show tunable ferromagnetism at room temperature and a thermally induced spin flip (TISF) in monolayers of V-doped WSe2. As vanadium concentrations increase within the WSe2 monolayers the saturation magnetization increases, and it is optimal at ~4at.% vanadium; the highest doping/alloying level ever achieved for V-doped WSe2 monolayers. The TISF occurs at ~175 K and becomes more pronounced upon increasing the temperature towards room temperature. We demonstrate that TISF can be manipulated by changing the vanadium concentration within the WSe2 monolayers. We attribute TISF to the magnetic field and temperature dependent flipping of the nearest W-site magnetic moments that are antiferromagnetically coupled to the V magnetic moments in the ground state. This is fully supported by a recent spin-polarized density functional theory calculation. Our findings pave the way for the development of novel spintronic and valleytronic nanodevices based on atomically thin magnetic semiconductors and stimulate further studies in this rapidly expanding research field of 2D magnetism.

description: In this paper the dynamics of Pierce diode with overcritical current under the influence of delay feedback is investigated. The system without feedback demonstrates complex behaviour including chaotic regimes. The possibility of oscillation regime control depending on the delay feedback parameter values is shown. Also the paper describes construction of a finite-dimensional model of electron beam behaviour, which is based on the Galerkin approximation by linear modes expansion. The dynamics of the model is close to the one given by the distributed model.

description: As encyclopaedia Britannica defines: ―Little Magazine is any of various small, usually avant-garde periodicals devoted to serious literary writings.‖ The name signifies most of all a usually non-commercial manner of editing, managing, and financing. They were published from 1880 through much of the 20th century and flourished in the U.S. and England, though French and German writers also benefited from them.
