An Empirical Analysis on The Influence of Agricultural Research and Development on Agricultural Output in Sub-Saharan Africa: An Endogenous Growth and Public Choice Theory Approach
Creators: name: Songose, Bismark Ibrahim
Publisher: name: My University
Year: 2022

description: Since independence, many sub-Saharan African (SSA) countries have strived to find permanent solutions to persistent patterns of sluggish economic growth and endemic poverty. For some of these economies, the solution to the problem demands the use of fiscal policy to build up quality and durable critical infrastructures, such as public health facilities, educational facilities, transportation networks, reliable energy supply and many others. According to countries like Ghana and Nigeria, the rationale for this growth strategy is the idea that building and utilizing these critical infrastructures create new employment opportunities and enhance economic productivity. For other economies, including Senegal and the Gambia, amplifying the role of monetary policy to bolster economic activity by controlling interest rates and inflation is seen as an equally important alternative growth strategy, and as a complement to the fiscal policy approach. Despite modest economic improvements after more than five decades, these challenges persist – economic growth continues to be sluggish, poverty rate has consistently failed to fall below the global average, infant mortality rate has not seen significant improvement, quality critical public infrastructures remain lacking, and most of the economies continue to be characterized by inefficiency. With the intention of exploring other growth alternatives for sub-Saharan African countries, the paper adopts a Two Sample Independent T-Test to empirically analyze the role of agricultural research and development (AR&D) in facilitating a sustainable and inclusive economic growth in the sub-continent. Using two groups of four sub-Saharan African countries as case studies – Group 1 (Togo and Sierra Leone) and Group 2 (Madagascar and Kenya) – the paper’s empirical analysis finds that a methodical investment in agricultural research and development has a strong potential to facilitate economic growth through an increase in the value of agricultural output.

description: The orbital instability of standing waves for the Klein-Gordon-Zakharov system has been established in two and three space dimensions under radially symmetric condition, see Ohta-Todorova (SIAM J. Math. Anal. 2007). In the one space dimensional case, for the non-degenerate situation, we first check that the Klein-Gordon-Zakharov system satisfies Grillakis-Shatah-Strauss' assumptions on the stability and instability theorems for abstract Hamiltonian systems, see Grillakis-Shatah-Strauss (J. Funct. Anal. 1987). As to the degenerate case that the frequency $|ω|=1/\sqrt{2}$, we follow Wu (ArXiv: 1705.04216, 2017) to describe the instability of the standing waves for the Klein-Gordon-Zakharov system, by using the modulation argument combining with the virial identity. For this purpose, we establish a modified virial identity to overcome several troublesome terms left in the traditional virial identity.

description: The linearized Boltzmann collision operator is fundamental in many studies of the Boltzmann equation and its main properties are of substantial importance. The decomposition into a sum of a positive multiplication operator, the collision frequency, and an integral operator is trivial. Compactness of the integral operator for monatomic single species is a classical result, while corresponding results for monatomic mixtures and polyatomic single species are more recently obtained. This work concerns the compactness of the operator for a multicomponent mixture of polyatomic species, where the polyatomicity is modeled by a discrete internal energy variable. With a probabilistic formulation of the collision operator as a starting point, compactness is obtained by proving that the integral operator is a sum of Hilbert-Schmidt integral operators and operators, which are uniform limits of Hilbert-Schmidt integral operators, under some assumptions on the collision kernel. The assumptions are essentially generalizations of the Grad's assumptions for monatomic single species. Self-adjointness of the linearized collision operator follows. Moreover, bounds on - including coercivity of - the collision frequency are obtained for a hard sphere like model. Then it follows that the linearized collision operator is a Fredholm operator, and its domain is also obtained.

Noether-Like Theorems for Causal Variational Principles

Subjects: subject: 510 Mathematik

description: The connection between symmetries and conservation laws as made by Noether's theorem is extended to the context of causal variational principles and causal fermion systems. Different notions of continuous symmetries are introduced. It is proven that these symmetries give rise to corresponding conserved quantities, expressed in terms of so-called surface layer integrals. In a suitable limiting case, the Noether-like theorems for causal fermion systems reproduce charge conservation and the conservation of energy and momentum in Minkowski space. Thus the conservation of charge and energy-momentum are found to be special cases of general conservation laws which are intrinsic to causal fermion systems.

description: An expansion of a density field or particle distribution in basis functions that solve the Poisson equation both provides an easily parallelized N-body force algorithm and simplifies perturbation theories. The expansion converges quickly and provides the highest computational advantage if the lowest order potential-density pair in the basis looks like the unperturbed galaxy or stellar system. Unfortunately, there are only a handful of such bases in the literature that limit this advantage. This paper presents an algorithm for deriving these bases to match a wide variety of galaxy models. The method is based on efficient numerical solution of the Sturm-Liouville equation and can be used for any geometry with a separable Laplacian. Two cases are described in detail. First, for the spherical case, the lowest order basis function pair may be chosen to be exactly that of the underlying model. The profile may be (1) cuspy or have a core and (2) truncated or of infinite extent. Second, the method yields a three-dimensional cylindrical basis appropriate for studying galactic disks. In this case, the vertical and radial bases are coupled; the lowest order radial part of the basis function can be chosen to match the underlying profile only in the disk plane. Practically, this basis is still a very good match to the overall disk profile and converges in a small number of terms. The ease of combining several bases makes this force solver ideally suited to multicomponent simulations, such as those of disks embedded in halos.

description: Attempts to incorporate topological information in supervised learning tasks have resulted in the creation of several techniques for vectorizing persistent homology barcodes. In this paper, we study thirteen such methods. Besides describing an organizational framework for these methods, we comprehensively benchmark them against three well-known classification tasks. Surprisingly, we discover that the best-performing method is a simple vectorization, which consists only of a few elementary summary statistics. Finally, we provide a convenient web application which has been designed to facilitate exploration and experimentation with various vectorization methods.

description: Die Kurzstudie »Zukünftige Potenziale urbaner Anbausysteme auf Quartiersebene« ist im Rahmen des vom Fraunhofer IAO initiierten Innovationsverbundes »Morgenstadt: Future District Alliance« entstanden. In einem ersten Schritt wird - untermauert durch spezifische Kennzahlen - ein Überblick über bestehende Entwicklungen gegeben, die auf eine zunehmende Relevanz der lokalen Lebensmittelproduktion in urbanen Räumen hinweisen. Dazu gehören der Klimawandel und damit verbundene Nachhaltigkeitsbestrebungen, ein sich wandelndes Verbraucherbewusstsein, Ressourcenverknappung, fortschreitende Urbanisierung und sich verschärfende internationale Konflikte. Es folgt ein Literaturreview zu den zugrundeliegenden Technologien der urbanen Lebensmittelproduktion, wie z.B. dem Vertical Farming, in dem bisherige Errungenschaften und Zukunftsaussichten aufgezeigt werden. Der zweite Teil der Kurzstudie ist der Methodik gewidmet. Es wird ein Potenzialberechnungstool vorgestellt, das auf Basis verschiedener bestehender Bewertungsinstrumente im landwirtschaftlichen Kontext entwickelt wurde und im Rahmen der Studie zur Ermittlung konkreter urbaner Anbaupotenziale für ausgewählte Quartiersentwicklungen eingesetzt wurde. Das Tool berücksichtigt drei Arten von urbanen Anbausystemen: Dachgewächshäuser, vertikale Indoor-Farmen und Urban Farming Container. Für diese wird auf Basis von Zukunftsszenarien, die zu erwartende Entwicklungen wie den zunehmenden Rückgang des Individualverkehrs und der Büronutzung beinhalten, ein von 2025 bis 2050 ansteigendes Nutzungspotenzial abgeleitet. Im letzten Teil der Kurzstudie wird das Potenzialberechnungstool auf Quartiere der Verbundpartner der Future District Alliance angewendet. Dabei werden nicht nur die Bruttoproduktion, sondern auch weitere Potenziale wie die Schaffung von Arbeitsplätzen, der Gesamtenergie- und Gesamtwasserverbrauch und die Einsparung von Ackerland berücksichtigt. Ziel der Kurzstudie ist es, verschiedenen städtischen Akteuren zu vermitteln, warum sie sich auf einen bevorstehenden Paradigmenwechsel hin zu einer verstärkt urbanen Lebensmittelproduktion einstellen sollten und wie sie innerhalb ihres Einflussbereichs entsprechende Vorkehrungen treffen können.

description: The Wigner Isobaric Multiplet Mass Equation (IMME) is the most fundamental prediction in nuclear physics with the concept of isospin. However, it was deduced based on the Wigner-Eckart theorem with the assumption that all charge-violating interactions can be written as tensors of rank two. In the present work, the charge-symmetry breaking (CSB) and charge-independent breaking (CIB) components of the nucleon-nucleon force, which contribute to the effective interaction in nuclear medium, are established in the framework of Brueckner theory with AV18 and AV14 bare interactions. Because such charge-violating components can no longer be expressed as an irreducible tensor due to density dependence, its matrix element cannot be analytically reduced by the Wigner-Eckart theorem. With an alternative approach, we derive a generalized IMME (GIMME) that modifies the coefficients of the original IMME. As the first application of GIMME, we study the long-standing question for the origin of the Nolen-Schiffer anomaly found in the Coulomb displacement energy of mirror nuclei. We find that the naturally-emerged CSB term in GIMME is largely responsible for explaining the Nolen-Schiffer anomaly.

description: Improving matrix-product state techniques based on the purification of the density matrix, we are able to accurately calculate the finite-temperature dynamic response of the infinite spin-1 XXZ chain with single-ion anisotropy in the Haldane, large-$D$ and antiferromagnetic phases. Distinct thermally activated scattering processes make a significant contribution to the spectral weight in all cases. In the Haldane phase intraband magnon scattering is prominent, and the onsite anisotropy causes the magnon to split into singlet and doublet branches. In the large-$D$ phase response, the intraband signal is separated from an exciton-antiexciton continuum. In the antiferromagnetic phase, holons are the lowest-lying excitations, with a gap that closes at the transition to the Haldane state. At finite temperatures, scattering between domain-wall excitations becomes especially important and strongly enhances the spectral weight for momentum transfer $π$.

description: We present techniques for incremental computing by introducing adaptive functional programming. As an adaptive program executes, the underlying system represents the data and control dependences in the execution in the form of a dynamic dependence graph. When the input to the program changes, a change propagation algorithm updates the output and the dynamic dependence graph by propagating changes through the graph and re-executing code where necessary. Adaptive programs adapt their output to any change in the input, small or large.We show that adaptivity techniques are practical by giving an efficient implementation as a small ML library. The library consists of three operations for making a program adaptive, plus two operations for making changes to the input and adapting the output to these changes. We give a general bound on the time it takes to adapt the output, and based on this, show that an adaptive Quicksort adapts its output in logarithmic time when its input is extended by one key.To show the safety and correctness of the mechanism we give a formal definition of AFL, a call-by-value functional language extended with adaptivity primitives. The modal type system of AFL enforces correct usage of the adaptivity mechanism, which can only be checked at run time in the ML library. Based on the AFL dynamic semantics, we formalize thechange-propagation algorithm and prove its correctness.

description: Building a quantum analog of classical deep neural networks represents a fundamental challenge in quantum computing. A key issue is how to address the inherent non-linearity of classical deep learning, a problem in the quantum domain due to the fact that the composition of an arbitrary number of quantum gates, consisting of a series of sequential unitary transformations, is intrinsically linear. This problem has been variously approached in the literature, principally via the introduction of measurements between layers of unitary transformations. In this paper, we introduce the Quantum Path Kernel, a formulation of quantum machine learning capable of replicating those aspects of deep machine learning typically associated with superior generalization performance in the classical domain, specifically, hierarchical feature learning. Our approach generalizes the notion of Quantum Neural Tangent Kernel, which has been used to study the dynamics of classical and quantum machine learning models. The Quantum Path Kernel exploits the parameter trajectory, i.e. the curve delineated by model parameters as they evolve during training, enabling the representation of differential layer-wise convergence behaviors, or the formation of hierarchical parametric dependencies, in terms of their manifestation in the gradient space of the predictor function. We evaluate our approach with respect to variants of the classification of Gaussian XOR mixtures - an artificial but emblematic problem that intrinsically requires multilevel learning in order to achieve optimal class separation.

description: In the local Universe, integrated X-ray emission from high-mass X-ray binaries (HMXBs) is dominated by the brightest ultraluminous X-ray sources (ULXs) with luminosity >10^40 erg/s. Such rare objects probably also dominated the production of X-rays in the early Universe. We demonstrate that a ULX with Lx~10^40-10^41 erg/s (isotropic-equivalent luminosity in the 0.1-10 keV energy band) shining for ~10^5 years (the expected duration of a supercritically accreting phase in HMXBs) can significantly ionise the ISM in its host dwarf galaxy of total mass M~10^7-10^8 Msun and thereby reduce its opacity to soft X-rays. As a result, the fraction of the soft X-ray (below 1 keV) radiation from the ULX escaping into the intergalactic medium (IGM) can increase from ~20-50% to ~30-80% over its lifetime. This implies that HMXBs can induce a stronger heating of the IGM at z>10 compared to estimates neglecting the ULX feedback on the ISM. However, larger galaxies with M>3 x 10^8 Msun could not be significantly ionised even by the brightest ULXs in the early Universe. Since such galaxies probably started to dominate the global star-formation rate at z<10, the overall escape fraction of soft X-rays from the HMXB population probably remained low, <30%, at these epochs.

description: Motivated by a recent work of Scardigli, Lambiase and Vagenas (SLV), we derive the GUP parameter, i.e. $α_0$, when the GUP has a linear and quadratic term in momentum. The value of the GUP parameter is obtained by conjecturing that the GUP-deformed black hole temperature of a Schwarzschild black hole and the modified Hawking temperature of a quantum-corrected Schwarzschild black hole are the same. The leading term in both cases is the standard Hawking temperature and since the corrections are considered as thermal, the modified and deformed expressions of temperature display a slight shift in the Hawking temperature. Finally, by equating the first correction terms, we obtain a value for the GUP parameter. In our analysis, the GUP parameter is not a pure number but depends on the ratio $\mpl /M$ with $\mpl$ to be the Planck mass and $M$ the black hole mass.

description: Using first principles calculations, we systematically study the elastic stiffness constants, mechanical properties, elastic wave velocities, Debye temperature, melting temperature, and specific heat of several thermodynamically stable crystal structures of Bi$_{x}$Sb$_{1-x}$ ($0 < x < 1$) binaries, which are of great interest due to their numerous inherent rich properties, such as thermoelectricity, thermomagnetic cooling, strong spin-orbit coupling (SOC) effects, and topological features in the electronic bandstructure. We analyze the bulk modulus ($B$), Young's modulus ($E$), shear modulus ($G$), $B/G$ ratio, and Poisson's ratio ($ν$) as a function of the Bi concentration in Bi$_{x}$Sb$_{1-x}$. The effect of SOC on above mentioned properties is further investigated. In general, we observe that the SOC effects cause elastic softening in most of the studied structures. Three monoclinic structures of Bi-Sb binaries are found to exhibit significantly large auxeticity. The Debye temperature and the magnitude of the elastic wave velocities monotonically decrease with increasing Bi-concentration. We also discuss the specific heat capacity versus temperature data for all studied binaries. Our theoretical results are in excellent agreement with the existing experimental and theoretical data. The comprehensive understanding of the material properties such as hardness, mechanical strength, melting temperature, propagation of the elastic waves, auxeticity, and heat capacity is vital for practical applications of the studied binaries.

description: We present continuum data from the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope (JCMT), and the Mid-Infrared Photometer for Spitzer (MIPS) on the Spitzer Space Telescope, at submillimetre and infrared wavelengths respectively. We study the Taurus molecular cloud 1 (TMC1), and in particular the region of the Taurus Molecular Ring (TMR). In the continuum data we see no real evidence for a ring, but rather we see one side of it only, appearing as a filament. We name the filament `the bull's tail'. The filament is seen in emission at 850, 450 and 160um, and in absorption at 70um. We compare the data with archive data from the Infra-Red Astronomical Satellite (IRAS) at 12, 25, 60, 100um, in which the filament is also seen in absorption. We find that the emission from the filament consists of two components: a narrow, cold (~8K), central core; and a broader, slightly warmer (~12K), shoulder of emission. We use a radiative transfer code to model the filament's appearance, either in emission or absorption, simultaneously at each of the different wavelengths. Our best fit model uses a Plummer-like density profile and a homogeneous interstellar dust grain population. Unlike previous work on a similar, but different filament in Taurus, we require no grain coagulation to explain our data.

description: Motivated by the wide range of kinematics covered by current and planned deep-inelastic scattering (DIS) facilities, we revisit the formalism, practical implementation, and numerical impact of target mass corrections (TMCs) for DIS on unpolarized nuclear targets. An important aspect is that we only use nuclear and later partonic degrees of freedom, carefully avoiding a picture of the nucleus in terms of nucleons. After establishing that formulae used for individual nucleon targets $(p,n)$, derived in the Operator Product Expansion (OPE) formalism, are indeed applicable to nuclear targets, we rewrite expressions for nuclear TMCs in terms of \mbox{re-scaled} (or averaged) kinematic variables. As a consequence, we find a representation for nuclear TMCs that is approximately independent of the nuclear target. We go on to construct a single-parameter fit for all nuclear targets that is in good numerical agreement with full computations of TMCs. We discuss in detail qualitative and quantitative differences between nuclear TMCs built in the OPE and the parton model formalisms, as well as give numerical predictions for current and future facilities.

Este organismo, integrado por representantes de las empresas generadoras, transmisoras, distribuidoras y el operador del sistema, inició su funcionamiento en el año 1995 y reviste interés, porque, no obstante su creación es legal, no hay claridad sobre los fundamentos de su origen, la vigencia de la norma de su creación, su naturaleza jurídica, la de sus funciones y de los actos que expide. A partir de la jurisprudencia y los conceptos que hay sobre su naturaleza jurídica y el de sus actos, haré mi propia interpretación sobre estos aspectos, y haré una descripción del funcionamiento del CNO desde el año 1995 y su lugar actual en el marco institucional, teniendo en cuenta la expedición de la Ley 2099 de 2021. Además, su funcionamiento histórico abre la posibilidad de analizar si reúne las características de las alternativas de la corregulación y la autorregulación de la OCDE.
description: Within the institutional framework of the Colombian electricity sector, the National Operation Council (CNO) was established by Laws 142 and 143 of 1994. lts primary role is to ensure the secure, reliable, and tost-effective operation of the National lnterconnected System. The Council also acts as the implementing body for the operational regulations set forth by the Commission for the Regulation of Energy and Gas (CREG). Although legally created, there remains ambiguity regarding the Council's foundational underpinnings, the validity of the norms governing its establishment, its legal character, the nature of its functions, and the status of its issued acts. l;)rawing on existing jurisprudence and ,oncepts that define the legal identity of the Council and its enactments, the following elaborate formulates an interpretation of these aspects. Moreover, 1 will provide an overview of the CNO activities since 1995 and its present position within the institutional framework, considering the provisions of Law 2099 of 2021. Furthermore, delving into its historical operations allows for an analysis of whether the Council aligns with the characteristics of alternative regulatory models such as OECD co-regulation and self-regulation.

description: We present a detailed X-ray spectral study of the quasar PG 1211+143 based on Chandra High Energy Transmission Grating Spectrometer (HETGS) observations collected in a multi-wavelength campaign with UV data using the Hubble Space Telescope Cosmic Origins Spectrograph (HST-COS) and radio bands using the Jansky Very Large Array (VLA). We constructed a multi-wavelength ionizing spectral energy distribution using these observations and archival infrared data to create XSTAR photoionization models specific to the PG 1211+143 flux behavior during the epoch of our observations. Our analysis of the Chandra-HETGS spectra yields complex absorption lines from H-like and He-like ions of Ne, Mg and Si which confirm the presence of an ultra-fast outflow (UFO) with a velocity ~ $-$17,300 km s$^{-1}$ (outflow redshift $z_{\rm out}$ ~ $-$0.0561) in the rest frame of PG 1211+143. This absorber is well described by an ionization parameter $\log ξ$ ~ 2.9 erg s$^{-1}$ cm and column density $\log N_{\rm H}$ ~ 21.5 cm$^{-2}$. This corresponds to a stable region of the absorber's thermal stability curve, and furthermore its implied neutral hydrogen column is broadly consistent with a broad Ly$α$ absorption line at a mean outflow velocity of ~ $-$16,980 km s$^{-1}$ detected by our HST-COS observations. Our findings represent the first simultaneous detection of a UFO in both X-ray and UV observations. Our VLA observations provide evidence for an active jet in PG 1211+143, which may be connected to the X-ray and UV outflows; this possibility can be evaluated using very-long-baseline interferometric (VLBI) observations.

description: We propose a spin polarizer device composed of a quantum dot connected to the spin polarized leads. The spin control of the current flowing through the device is entirely due to the Coulomb interactions present inside the dot. We show that the initial polarization present in the source lead can be reverted or suppressed just by manipulating the gate voltage acting on the dot, the presence of the external magnetic field is not required. The influence of the temperature and finite bias on the efficiency of the current spin switching effect is also discussed.

description: The exterior geometry of a neutron star can be approximated by relativistic multipole moments of a parametrized metric using Ernst potential formalism. This spacetime can be tested with electromagnetic wave observation of astrophysical black holes. In the present paper, I simulate X-ray reflection spectra of a thin accretion disk with future X-ray missions. The purpose of this work is to understand whether X-ray reflection spectroscopy can distinguish the neutron star from the Kerr solution of General Relativity. I found that for the higher value of spin and multipole moment parameters, there are small differences in the shape of neutron star iron lines. It is hard to distinguish neutron star iron lines from Kerr ones due to the small deviations. Also, electromagnetic wave observation of slow rotating neutron stars is marginally consistent with Kerr black holes of general relativity.

description: We consider the singular values of certain Young diagram shaped random matrices. For block-shaped random matrices, the empirical distribution of the squares of the singular eigenvalues converges almost surely to a distribution whose moments are a generalisation of the Catalan numbers. The limiting distribution is the density of a product of rescaled independent Beta random variables and its Stieltjes-Cauchy transform has a hypergeometric representation. In special cases we recover the Marchenko-Pastur and Dykema-Haagerup measures of square and triangular random matrices, respectively. We find a further factorisation of the moments in terms of two complex-valued random variables that generalises the factorisation of the Marcenko-Pastur law as product of independent uniform and arcsine random variables.

description: The Fourier theorem states that any time-series can be decomposed into a set of sinusoidal frequencies, each with its own phase and amplitude. The literature suggests that some frequencies are important to reproduce key qualities of eye-movements ("signal") and some of frequencies are not important ("noise"). To investigate what is signal and what is noise, we analyzed our dataset in three ways: (1) visual inspection of plots of saccade, microsaccade and smooth pursuit exemplars; (2) analysis of the percentage of variance accounted for (PVAF) in 1,033 unfiltered saccade trajectories by each frequency band; (3) analyzing the main sequence relationship between saccade peak velocity and amplitude, based on a power law fit. Visual inspection suggested that frequencies up to 75 Hz are required to represent microsaccades. Our PVAF analysis indicated that signals in the 0-25 Hz band account for nearly 100% of the variance in saccade trajectories. Power law coefficients (a, b) return to unfiltered levels for signals low-pass filtered at 75 Hz or higher. We conclude that to maintain eye movement signal and reduce noise, a cutoff frequency of 75 Hz is appropriate. We explain why, given this finding, a minimum sampling rate of 750 Hz is suggested.

description: The spatial distribution of the local density of states (LDOS) at Mn acceptors near the (110) surface of p-doped InAs is investigated by Scanning Tunneling Microscopy (STM). The shapes of the acceptor contrasts for different dopant depths under the surface are analyzed. Acceptors located within the first ten subsurface layers of the semiconductor show a lower symmetry than expected from theoretical predictions of the bulk acceptor wave function. They exhibit a (001) mirror asymmetry. The degree of asymmetry depends on the acceptor atoms' depths. The measured contrasts for acceptors buried below the 10th subsurface layer closely match the theoretically derived shape. Two effects are able to explain the symmetry reduction: the strain field of the surface relaxation and the tip-induced electric field.

description: This paper presents dsync, a file transfer system that can dynamically adapt to a wide variety of environments. While many transfer systems work well in their specialized context, their performance comes at the cost of generality, and they perform poorly when used elsewhere. In contrast, dsync adapts to its environment by intelligently determining which of its available resources is the best to use at any given time. The resources dsync can draw from include the sender, the local disk, and network peers. While combining these resources may appear easy, in practice it is difficult because these resources may have widely different performance or contend with each other. In particular, the paper presents a novel mechanism that enables dsync to aggressively search the receiver’s local disk for useful data without interfering with concurrent network transfers. Our evaluation on several workloads in various network environments shows that dsync outperforms existing systems by a factor of 1.4 to 5 in one-to-one and one-to-many transfers.
