Collier in Melanesia: A discussion of Paul Collier's 'The bottom billion: Why the poorest countries are failing and what can be done about it'

Year: 2008

description: Former director of development research at the World Bank and now Professor of Economics and Director of the Centre for the Study of African Economies at Oxford University, Paul Collier has written a broad and brave book on why one sixth of the world’s population suffer long-term poverty and poor government, what can be done about it, and why it is in the interests of all nations to do something.1 Collier’s aim it to identify the ‘traps’ that ensnare and hold poor nations and the policies that are most likely to lead to their escape. His immediate concern is not with the millions of poor within rich and middle-level nations – the problems of opportunity and distribution. He is defining questions and presenting answers at the broadest level on other major issues of our time: how do citizens in the failed and faltering states begin to turn them into efficient and fair nation-states, and how do those in developed nations, multi-national organizations and non-government agencies transfer material and non-material aid to under-developed nations so that it has a measurable, beneficial effect. The quotes from the relevant and eminent on the back cover of The Bottom Billions make high claims: ‘The best nonfiction book so far this year’ (Nicholas Kristof), ‘Path-breaking’ (George Soros), and ‘Should be compulsory reading’ (The Economist). Given the topic, the recommendations, and its immediate relevance to international aid policy and practice, this is a book worth close examination. In a study that draws its evidence from across the globe and offers analysis and answers for all donor nations, multinational agencies and recipients, it is inevitable that readers will check for accuracy against those bits of the globe familiar to them. So what does Collier say about Australia and the region?

description: Gaussian white noise is frequently used to model fluctuations in physical systems. In Fokker-Planck theory, this leads to a vanishing probability density near the absorbing boundary of threshold models. Here we derive the boundary condition for the stationary density of a first-order stochastic differential equation for additive finite-grained Poisson noise and show that the response properties of threshold units are qualitatively altered. Applied to the integrate-and-fire neuron model, the response turns out to be instantaneous rather than exhibiting low-pass characteristics, highly non-linear, and asymmetric for excitation and inhibition. The novel mechanism is exhibited on the network level and is a generic property of pulse-coupled systems of threshold units.

Stochastic processes in population studies
Creators: name: Barrett, Marguerite Elaine
Publisher: name: University of British Columbia
Year: 2011

description: This paper develops a stochastic model for the growth of two interacting populations: when one species preys upon the other. The spatial distribution of the populations is considered, that of the prey being assumed to be clustered and quasi-uniform. This latter distribution is discussed in some detail, and it is found that, although it has been suggested that clustering of the prey may be a protective device against predators, any differences in the stochastic models for clustered and unclustered populations lie only in the constant coefficients involved in the formulation of the model. The approach used in developing the proposed model is that of Chiang. The size of the prey and predator populations; are assumed to be random variables X(t) and Y(t) respectively, and certain assumptions are made concerning the birth-rate and death-rate In either population. These assumptions are based on the deterministic equations (formula omitted). These equations are modifications of equations published by Leslie in 1958. Differential equations are developed for the rate of change of the probability that X(t)=x and Y(t)=y, by giving transition probabilities in some small interval of time and letting the interval shrink to a point. Hence differential equations, for the rate of change of the joint probability generating function of X and Y, and for the rate of change of the joint factorial moments of X and Y are obtained. Because of the complicated nature of these equations, however, no attempt is made to solve them.

Kosterlitz-Thouless transition in thin films: A Monte Carlo study of three-dimensional lattice models
Creators: name: Hasenbusch, Martin
Publisher: name: arXiv
Year: 2008
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study the phase transition of thin films in the three-dimensional XY universality class. To this end, we perform a Monte Carlo study of the improved two-component ϕ^4 model, the improved dynamically diluted XY model and the standard XY model on the simple cubic lattice. We study films of a thickness up to L_0=32 lattice spacings. In the short direction of the lattice free boundary conditions are employed. Using a finite size scaling (FSS) method, proposed recently, we determine the transition temperature with high accuracy. The effectively two-dimensional finite size scaling behaviour of the Binder cumulant U_4, the second moment correlation length over the lattice size ξ_{2nd}/L, the ratio of the partition functions with anti-periodic and periodic boundary conditions Z_a/Z_p and the helicity modulus Υclearly confirm the Kosterlitz-Thouless nature of the transition. We analyse the scaling of the transition temperature with the thickness L_0 of the film. The predictions of the renormalization group (RG) theory are confirmed. We compute the universal ratio of the thickness of the film L_0 and the transversal correlation length ξ_T in the three-dimensional thermodynamic limit at the Kosterlitz-Thouless transition temperature of a film of thickness L_0: [L_{0,KT}/ξ_T]^* = 1.595(7). This results can be compared with experimental results on thin films of 4He near the λ-transition.

Extending the QCD Perturbative Domain to Higher Energies
Creators: name: Ciafaloni, Marcello
Publisher: name: ECONF C030614:013,2003
Year: 2003

description: After a brief introduction to low-x QCD and to resummation approaches, I
illustrate the predictions for the gluon Green function and splitting function
of a recent renormalization-group improved small-x resummation scheme. I argue,
on this basis, that the range of validity of perturbative calculations is
considerably extended in rapidity with respect to leading log expectations. The
perturbative high-energy exponents are predicted in a phenomenologically
interesting range, and significant preasymptotic effects are found. In
particular, the splitting function shows a shallow dip in the moderate-x
region, followed by the expected small-x power increase.

A general formalism for single and double spin asymmetries in inclusive
  hadron production

Publisher: name: INFN Open Access Repository
Year: 2004

description: We present a calculation of single and double spin asymmetries for inclusive
hadron production in hadronic collisions. Our approach is based on Leading
Order (LO) perturbative QCD and generalized factorization theorems, with full
account of intrinsic parton momentum, k_T, effects. This leads to a new class
of spin and k_T-dependent distribution and fragmentation functions. Limiting
ourselves to consider leading twist functions, we show how they could play a
relevant role in producing non-vanishing spin asymmetries.

Subjects: Deep learning

description: Parkinson’s disease (PD) is a progressive and neurodegenerative condition causing motor impairments. One of the major motor related impairments that present biggest challenge is freezing of gait (FOG) in Parkinson’s patients. In FOG episode, the patient is unable to initiate, control or sustain a gait that consequently affects the Activities of Daily Livings (ADLs) and increases the occurrence of critical events such as falls. This paper presents continuous monitoring ADLs and classification freezing of gait episodes using Wi-Fi and radar imaging. The idea is to exploit the multi-resolution scalograms generated by channel state information (CSI) imprint and micro-Doppler signatures produced by reflected radar signal. A total of 120 volunteers took part in experimental campaign and were asked to perform different activities including walking fast, walking slow, voluntary stop, sitting down & stand up and freezing of gait. Two neural networks namely Autoencoder and a proposed enhanced Autoencoder were used classify ADLs and FOG episodes using data fusion process by combining the images acquired from both sensing techniques. The Autoencoder provided overall classification accuracy of ∼87% for combined datasets. The proposed algorithm provided significantly better results by presenting an overall accuracy of ∼98% using data fusion.

description: We have investigated the stellar and wind properties of a sample of five late-type O dwarfs in order to address the weak wind problem. A grid of TLUSTY models was used to obtain the stellar parameters, and the wind parameters were determined by using the CMFGEN code. We found that the spectra have mainly a photospheric origin. A weak wind signature is seen in CIV 1549, from where mass-loss rates consistent with previous CMFGEN results regarding O8-9V stars were obtained. A discrepancy of roughly 2 orders of magnitude is found between these mass-loss rates and the values predicted by theory (Mdot(Vink)), confirming a breakdown or a steepening of the modified wind momentum-luminosity relation at log L/Lsun < 5.2. We have estimated the carbon abundance for the stars of our sample and concluded that its uncertainty cannot cause the weak wind problem. Upper limits on Mdot were established for all objects using lines of different ions, namely, PV 1118,28, CIII 1176, NV 1239,43, Si IV 1394,03, and NIV 1718. All the values obtained are also in disagreement with theoretical predictions, bringing support to the reality of weak winds. Together with CIV 1549, the use of NV 1239,43 results in the lowest mass-loss rates: the upper limits indicate that Mdot must be less than about -1.0 dex Mdot(Vink). Regarding the other transitions, the upper limits still point to low rates: Mdot must be less than about $(-0.5 \pm 0.2)$ dex Mdot(Vink). We have studied the behavior of the Halpha line with different mass-loss rates. We have also explored ways to fit the observed spectra with Mdot(Vink). By using large amounts of X-rays, we verified that few wind emissions take place, as in weak winds. However, unrealistic X-rays luminosities had to be used (log Lx/Lbol > -3.5) (abridged).

QCD with the inclusion of spin and k_T effects, of unpolarized cross sections
for the Drell-Yan process and for inclusive pion and photon production in

satisfactory agreement between theoretical predictions and experimental data.
This supports the study of spin effects and transverse single spin asymmetries

Ionization cooled ultra pure beta-beams for long distance neu-e to
  neu-mu transitions, theta13 phase and CP-violation
Creators: name: Rubbia, Carlo
Publisher: name: INFN Open Access Repository
Year: 2006

description: The key process is the observation of tiny oscillation mixing between numu
and nue related to so far unknown theta13 amplitude, at distances corresponding
to an invariant neutrino flight path around about 2.0 MeV/km. Zucchelli [12]
has proposed the production of very pure neue beams (beta beams), in which
relativistic radio-nuclides are stored in a high energy storage ring and decay
in a long straight section pointing toward the neutrino detector far away. This
method produces ultra pure anti-neue (He-6) and neue (Ne-18) with a negligible
numu contamination (10-5). A novel kind of beta element production has been
recently proposed [15] in which slow (v about 0.1 c) fully ionized ions are
stored in a very small storage ring. Products like the isomeric doublet
Li-7(d,p) Li-8 and Li-6(He3,n) B-8 are stopped in some foils few micron thick,
from which they quickly diffuse as neutral atoms. The improvements are shown to
be considerable. An ion source, a chain of several accelerators in cascade and
a high energy storage/decay ring can produce a B-8 induced nue spectrum which
has as much as 7.7 times higher energy than the one from He-6 induced anti-nue
for a given magnetic rigidity of the storage ring. At a given neutrino energy,
the CC cross sections for nue are about 3 times larger than the ones of
anti-nue while the NC/CC inelastic pion background faking muons is about 3
times smaller. An optimal neu-e source might be fully ionized B-8 from the 120
GeV Main Energy Injector at FNAL, followed by a decay storage ring and a
neutrino fly path of about 700-800 km. As detector we consider a LAr TPC with a
fiducial mass of 50 to 100 kton. Such a technology should permit to detect a
background free signal for sin2(2theta13) as small as about 6.0 x 10-4. By
comparison, the present experimental limit is < 0.14.

Non-Markovian Quantum Jumps in Excitonic Energy Transfer

Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)

description: We utilize the novel non-Markovian quantum jump (NMQJ) approach to stochastically simulate exciton dynamics derived from a time-convolutionless master equation. For relevant parameters and time scales, the time-dependent, oscillatory decoherence rates can have negative regions, a signature of non-Markovian behavior and of the revival of coherences. This can lead to non-Markovian population beatings for a dimer system at room temperature. We show that strong exciton-phonon coupling to low frequency modes can considerably modify transport properties. We observe increased exciton transport, which can be seen as an extension of recent environment-assisted quantum transport (ENAQT) concepts to the non-Markovian regime. Within the NMQJ method, the Fenna-Matthew-Olson protein is investigated as a prototype for larger photosynthetic complexes.

description: A search has been made for the radiative capture reaction d(α,ɤ)Li⁶ at the energy corresponding to the 2.184 Mev level in Li⁶. The search was carried out using heavy ice targets varying from 100 Kev to 700 Kev thick. The radiative capture reaction was not observed. An upper limit on the resonant capture process was set at (1.4 ± 0.6) x 10⁻³¹ cm². A gamma radiation peak was observed at 1.64 Mev for runs on D₂O, H₂O, and tungsten oxide targets. The cross-section was roughly estimated at 4 x 10⁻²⁹ cm². This radiation was attributed to the reaction O¹⁷(α,n)Ne²⁰.

Diffusion and localization for the Chirikov typical map

description: We consider the classical and quantum properties of the "Chirikov typical map", proposed by Boris Chirikov in 1969. This map is obtained from the well known Chirikov standard map by introducing a finite number $T$ of random phase shift angles. These angles induce a random behavior for small time scales ($tT$). We identify the classical chaos border $k_c\sim T^{-3/2} \ll 1$ for the kick parameter $k$ and two regimes with diffusive behavior on short and long time scales. The quantum dynamics is characterized by the effect of Chirikov localization (or dynamical localization). We find that the localization length depends in a subtle way on the two classical diffusion constants in the two time-scale regime.

Un nuovo approccio alla ricerca di vita extraterrestre intelligente. Come gli astronomi vanno a caccia di esopianeti facendo affidamento sul sistema dei transiti, allo stesso modo una civiltà aliena potrebbe aver individuato la Terra grazie al movimento di rivoluzione attorno al Sole, la nostra stella.

description: We calculate the contribution of semi-hadronic states with pseudoscalar $P=π^0, η$ and scalar ($σ$(550))meson accompanied with real photon as an intermediate state of a heavy photon to the anomalous magnetic moment of muon. We consider the intermediate states with $π_0$ and $σ$ as a hadrons in frames of Nambu-Jona-Lasinio model. The contribution of $π_0γ$ state is in agreement with results obtained in previous theoretical considerations as well as with experimental data $a_μ^{π_0γ}\approx 4.5 \times 10^{-10}$, besides we estimate $a_μ^{ηγ}=0.7 \times 10^{-10}, a_μ^{σγ} \sim 1.5 \times 10^{-11}, a_μ^{π^+π^-γ} \sim 3.2 \times 10^{-10}.$ We discass as well the LbL mechanism with $a_μ^{lbl}=10.5 \cdot 10^{-10}.$

Euclidean versus hyperbolic congestion in idealized versus experimental networks
Creators: name: Jonckheere, Edmond

Publisher: name: arXiv
Year: 2009
Subjects: subject: Networking and Internet Architecture (cs.NI)
subject: FOS: Computer and information sciences

description: This paper proposes a mathematical justification of the phenomenon of extreme congestion at a very limited number of nodes in very large networks. It is argued that this phenomenon occurs as a combination of the negative curvature property of the network together with minimum length routing. More specifically, it is shown that, in a large n-dimensional hyperbolic ball B of radius R viewed as a roughly similar model of a Gromov hyperbolic network, the proportion of traffic paths transiting through a small ball near the center is independent of the radius R whereas, in a Euclidean ball, the same proportion scales as 1/R^{n-1}. This discrepancy persists for the traffic load, which at the center of the hyperbolic ball scales as the square of the volume, whereas the same traffic load scales as the volume to the power (n+1)/n in the Euclidean ball. This provides a theoretical justification of the experimental exponent discrepancy observed by Narayan and Saniee between traffic loads in Gromov-hyperbolic networks from the Rocketfuel data base and synthetic Euclidean lattice networks. It is further conjectured that for networks that do not enjoy the obvious symmetry of hyperbolic and Euclidean balls, the point of maximum traffic is near the center of mass of the network.

Tripartite entanglement in parametric down-conversion with spatially-structured pump

description: Most investigations of multipartite entanglement have been concerned with temporal modes of the electromagnetic field, and have neglected its spatial structure. We present a simple model which allows to generate tripartite entanglement between spatial modes by parametric down-conversion with two symmetrically-tilted plane waves serving as a pump. The characteristics of this entanglement are investigated. We also discuss the generalization of our scheme to 2N+1-partite entanglement using 2N symmetrically-tilted plane pump waves. Another interesting feature is the possibility of entanglement localization in just two spatial modes.
