description: This paper examines some of the causes of poor connectivity in developing countries, and suggests options for overcoming the so-termed digital divide. Based on a techno-economic analysis of connectivity technologies and design, I show that technical limitations per se are not the bottleneck for widespread connectivity; rather, design, policy, and regulatory challenges are the reasons for high costs (which determines penetration to a large extent). The first part of this paper deals with the “digital divide” and a brief look at existing measures and difficulties with such measures, such as issues of granularity. I present a starting point for a new framework for the digital divide, based on what we call the 4Cs of Information and Communications Technology (ICT): Computers, Connectivity, Content, and (human) Capacity. The next section focuses on the Connectivity aspect of ICT, and examines cost components of different technologies. While there are obvious differences between technologies in terms of speeds, reach, and infrastructure, there are non-technical implications of such choices, such as legacy requirements, competition, leapfrogging, etc. Once we formulate a basic, indicative, network design for broadband, using estimated costs and some limited real-world emerging economy data, we can see what reasons there are for higher costs (and prices) than the model would indicate. We identify over a dozen policy add-ons (such as ISP licensing, spectrum fees, taxes, limits on applications such as VoIP, etc.) that raise the costs to end-users. Expanding from the idealized model, I also present a new design for broadband across Africa (“FiberAfrica”) based on GIS modeling and a bottom-up design. This is not an idealized model but a first attempt at a hypothetical continental network based on available data. It not only includes appropriate technologies (optical fibers and fixed broadband wireless) but also innovative business models such as open access networks. The analysis shows such a design could bring affordable, accessible broadband to the majority of Africans, for a one-time capital cost of only a little over $1/capita.

description: Earl Henry Hodgson was in the Royal Army Ordnance Corps in World War Two.At the time that he was called up, he was living down Brunswick Street in Leamington Spa and working as a postman. He considered joining the local fire brigade instead, but he had a foot injury from an agricultural accident years before. He had been in the Royal Warwickshire Regiment for a couple of years in the 1920s. If he re-joined them, they said that he would automatically become sergeant. However, he said that he wanted a change and joined the Royal Army Ordnance Corps.He would not readily talk about the war. A few stories did come out over the years though. He said that, in the run up to D Day, they were obviously very busy getting things packed for the soldiers taking part. After D Day, he was stationed in Germany for a while. If ever you asked him about that, he would just say that the Germans kept the streets clean. My mother said that she could remember him coming home on leave when he was stationed in the UK a few times. He often had to rush to catch the train to get him back to barracks in time.My mother had a few memories from that time. There used to be a large automotive parts factory near them called Lockheed. She remembered her mother saying that they were bombing Lockheed and could remember looking out of the window and seeing a German bomber. Down their road, there were quite a few Czech and Polish RAF air crew billeted.

Simultaneous weak measurement of non-commuting observables

description: In contrast to a projective quantum measurement in which the system is projected onto an eigenstate of the measured operator, in a weak measurement the system is only weakly perturbed while only partial information on the measured observable is obtained. A full description of such measurement should describe the measurement protocol and provide an explicit form of the measurement operator that transform the quantum state to its post measurement form. A simultaneous measurement of non-commuting observables cannot be projective, however the strongest possible such measurement can be defined as providing their values at the smallest uncertainty limit. Starting with the Arthurs and Kelly (AK) protocol for such measurement of position and momentum, we derive a systematic extension to a corresponding weak measurement along three steps: First, a plausible form of the weak measurement operator analogous to the Gaussian Kraus operator often used to model a weak measurement of a single observable is obtained by projecting a naïve extension (valid for commuting observable) onto the corresponding Gabor space. Second, we show that the so obtained set of measurement operators satisfies the normalization condition for the probability to obtain given values of the position and momentum in the weak measurement operation, namely that this set constitutes a positive operator valued measure (POVM) in the position-momentum space. Finally, we show that the so-obtained measurement operator corresponds to a generalization of the AK measurement protocol in which the initial detector wavefunctions is suitable broadened.

description: Many US states rely on energy efficiency goals as a strategy to reduce CO2e emissions and air pollution, to minimize investments in new power plants, and to create jobs. For those energy efficiency interventions that are cost-effective, i.e., saving money andreducing energy, consumers may increase their use of energy services, or re-spend cost savings on other carbon- and energy-intensive goods and services. In this paper, we simulate the magnitude of these 'rebound effects' in each of the 50 states in terms of CO2e emissions, focusing on residential electric end-uses under plausible assumptions. We find that a 10% reduction in annual electricity use by a household results in an emissions' reduction penalty ranging from 0.1 ton CO2e in California to 0.3 ton CO2e in Alabama (from potential emissions reductions of 0.3 ton CO2e and 1.6 ton CO2e, respectively, in the no rebound case). Rebound effects, percentage-wise, range from 6% in West Virginia (which has a high-carbon electricity and low electricity prices), to as high as 40% in California (which has low-carbon electricity and high electricity prices). The magnitude of rebound effects percentage-wise depends on the carbon intensity of the grid: in states with low emissions factors and higher electricity prices, such as California, the rebound effects are much larger percentage-wise than in states like Pennsylvania. Conversely, the states with larger per cent rebound effects are the ones where the implications in terms of absolute emissions changes are the smallest.

description: We use the results from a recent investigation of hard parton-parton gravitational scattering in the ADD scenario to make semi-quantitative predictions for a few standard high-ET jet observables at the LHC. By implementing these gravitational scattering results in the Pythia event generator and combining it with the Charybdis generator for black holes, we investigate the effects of large extra dimensions and find that, depending on the width of the brane, the relative importance of gravitational scattering and black hole production may change significantly. For the cases where gravitational scatterings are important we discuss how to distinguish gravitational scattering from standard QCD partonic scatterings. In particular we point out that the universal colorlessness of elastic gravitational scattering implies fewer particles between the hard jets, and that this can be used in order to distinguish an increased jet activity induced by gravitational scattering from an increased jet activity induced by eg. super-symmetric extensions where the interaction is colorful.

description: Model atmospheres of isolated neutron stars with low magnetic field are calculated with Compton scattering taking into account. Models with effective temperatures 1, 3 and 5 MK, with two values of surface gravity log(g)g = 13.9 and 14.3), and different chemical compositions are calculated. Radiation spectra computed with Compton scattering are softer than the computed with Thomson scattering at high energies (E > 5 keV) for hot (T_eff > 1 MK) atmospheres with hydrogen-helium composition. Compton scattering is more significant to hydrogen models with low surface gravity. The emergent spectra of the hottest (T_eff > 3 MK) model atmospheres can be described by diluted blackbody spectra with hardness factors ~ 1.6 - 1.9. Compton scattering is less important for models with solar abundance of heavy elements.

description: Multi-photon absorption processes have a nonlinear dependence on the amplitude of the incident optical field i.e. the number of photons. However, multi-photon absorption is generally weak and multi-photon events occur with extremely low probability. Consequently, it is extremely challenging to engineer quantum nonlinear devices that operate at the single photon level and the majority of quantum technologies have to rely on single photon interactions. Here, we demonstrate experimentally and theoretically that exploiting coherent absorption of N = 2 N00N states makes it possible to enhance the number of two-photon states that are absorbed. An absorbing metasurface placed inside a Sagnac-style interferometer into which we inject an N = 2 N00N state, exhibits two-photon absorption with 40.5% efficiency, close to the theoretical maximum. This high probability of simultaneous absorption of two photons holds the promise for applications in fields that require multi-photon upconversion but are hindered by high peak intensities.

Constraints on the gluon Sivers distribution via transverse single spin asymmetries at midrapidity in p(transv. polarized) p -> pi^0 X processes at BNL RHIC

description: We consider the recent RHIC data on the transverse single spin asymmetry (SSA) A_N, measured in p(transv. polarized) p -> pi^0 X processes at mid-rapidity by the PHENIX collaboration. The measurement is consistent with a vanishing SSA. We analyze this experimental information within a hard scattering approach based on a generalized QCD factorization scheme, with unintegrated, transverse momentum dependent (TMD), parton distribution and fragmentation functions. It turns out that, in the kinematical region of the data, only the gluon Sivers effect could give a large contribution to A_N; its vanishing value is thus an indication about the possible size of the gluon Sivers function (GSF). Approximate upper limits on its magnitude are derived. Additional constraints obtained combining available parameterizations of the quark Sivers function and the Burkardt sum rule (BSR) for the Sivers distributions are also discussed.

description: We derive optimal filters on the sphere in the context of detecting compact objects embedded in a stochastic background process. The matched filter and the scale adaptive filter are derived on the sphere in the most general setting, allowing for directional template profiles and filters. The performance and relative merits of the two optimal filters are discussed. The application of optimal filter theory on the sphere to the detection of compact objects is demonstrated on simulated mock data. A naive detection strategy is adopted, with an initial aim of illustrating the application of the new optimal filters derived on the sphere. Nevertheless, this simple object detection strategy is demonstrated to perform well, even a low signal-to-noise ratio. Code written to compute optimal filters on the sphere (S2FIL), to perform fast directional filtering on the sphere (FastCSWT) and to construct the simulated mock data (COMB) are all made publicly available from http://www.mrao.cam.ac.uk/~jdm57/

description: The contributions of supersymmetric particles in the isospin symmetry violation in B -> K* gamma decay mode are investigated. The model parameters are adopted from minimal Supergravity with minimal flavor violation. A complete scan of the mSUGRA parameter space has been performed, using the next to leading supersymmetric contributions to the relevant Wilson coefficients. The results are compared to recent experimental data in order to obtain constraints on the parameter space. We point out that isospin asymmetry can prove to be an interesting observable and imposes severe restrictions on the allowed parameter space, in particular for large values of tan(beta). The constraints obtained with isospin asymmetry also appear as more restricting than the ones from the branching ratio of B -> X_s gamma.

description: An interacting bilayer electron system provides an extended platform to study electron-electron interaction beyond single layers. We report here experiments demonstrating that the layer densities of an asymmetric bilayer electron system oscillate as a function of perpendicular magnetic field that quantizes the energy levels. At intermediate fields, this interlayer charge transfer can be well explained by the alignment of the Landau levels in the two layers. At the highest fields where both layers reach the extreme quantum limit, however, there is an anomalous, enhanced charge transfer to the majority layer. Surprisingly, when the minority layer becomes extremely dilute, this charge transfer slows down as the electrons in the minority layer condense into a Wigner crystal. Furthermore, by examining the quantum capacitance of the dilute layer at high fields, the screening induced by the composite fermions in an adjacent layer is unveiled. The results highlight the influence of strong interaction in interlayer charge transfer in the regime of very high fields and low Landau level filling factors.

description: Coal-to-liquids (CTL) processes generate synthetic liquid fuels like gasoline and diesel fuel from coal. One main concern of coal liquids, however, is the large emissions of carbon dioxide (CO2 ) from the CTL process. These emissions can be mitigated using carbon capture and sequestration (CCS) technology. A comprehensive techno-economic assessment model of liquids-only and poly-generation (producing liquid fuels plus electricity) CTL plants, capable of incorporating CCS is developed. To account for inherent uncertainties and variability, ranges and probability distributions are given to different cost parameters. Finally, the capability of a poly-generation CTL plant in mitigating CO2 emissions by displacing conventional coal-fired power plants while producing liquid fuels is also investigated.

description: Memories from the time before D Day, when I was a little boy living by the sea on outskirts of Bognor Regis:

*Armoured cars lined up under camouflage netting in Aldwick.
*Troops giving me chocolate as they marched by in Aldwick.
*A doodle bug exploding in Pagham Harbour, after my sister and I had been hastily pushed into our shelter on our mother's hearing it buzzing overhead.
*Planes taking off over our heads from Tangmere aerodrome, presumably towing gliders across to Normandy.
*Seeing con-trails winding way up in the cloudless summer skies and the faint chatter of machine guns. Perhaps Douglas Bader, who apparently had a house on the Aldwick Bay Estate.
*V-Day bunting
*Huge explosions over the Channel, said to be armouries being blown up?
*Dad coming home from service, with bananas!

description: Our goal is to study the effects of the UV radiation from the first stars, quasars and decays of the hypothetical Super Heavy Dark Matter (SHDM) particles on the formation of primordial bound objects in the Universe. We trace the evolution of a spherically symmetric density perturbation in the Lambda Cold Dark Matter ($Λ$CDM) and MOND models, solving the frequency-dependent radiative transfer equation, non-equilibrium chemistry, and one-dimensional gas hydrodynamics. We concentrate on the destruction and formation processes of the H$_2$ molecule, which is the main coolant in the primordial objects.

description: My grandad was Flight Sargeant 'Bill' George William Green who served with the 582nd Squadron, attached to 101 Squadron during the last year of the Second World War. He was a rear gunner (tail end charlie) on Lancasters, flying out of numerous bases in Lincolnshire. One operation he took part in was the raid on Chemnitz in Germany in 1945, a day after the Dresden fire bombing. He would recall that the bomb run on Chemnitz was like bombing in daylight from the fires from Dresden which was still burning.
Interpreting Spectral Energy Distributions from Young Stellar Objects. II. Fitting observed SEDs using a large grid of pre-computed models

description: We present a method to analyze the spectral energy distributions (SEDs) of young stellar objects (YSOs). Our approach is to fit data with pre-computed 2-D radiation transfer models spanning a large region of parameter space. This allows us to determine not only a single set of physical parameter values but the entire range of values consistent with the multi-wavelength observations of a given source. In this way we hope to avoid any over-interpretation when modeling a set of data. We have constructed spectral energy distributions from optical to sub-mm wavelengths, including new Spitzer IRAC and MIPS photometry, for 30 young and spatially resolved sources in the Taurus-Auriga star-forming region. We demonstrate fitting model SEDs to these sources, and find that we correctly identify the evolutionary stage and physical parameters found from previous independent studies, such as disk mass, disk accretion rate, and stellar temperature. We also explore how fluxes at various wavelengths help to constrain physical parameters, and show examples of degeneracies that can occur when fitting SEDs. A web-based version of this tool is available to the community at http://www.astro.wisc.edu/protostars .

The Onset of Quark-Hadron Duality in Pion Electroproduction

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A large data set of charged-pion electroproduction from both hydrogen and deuterium targets has been obtained spanning the low-energy residual-mass region. These data conclusively show the onset of the quark-hadron duality phenomenon, as predicted for high-energy hadron electroproduction. We construct several ratios from these data to exhibit the relation of this phenomenon to the high-energy factorization ansatz of electron-quark scattering and subsequent quark-to- pion production mechanisms.

description: The objective of this research is to develop, implement, and demonstrate a capability for evaluating performance and cost uncertainties in integrated gasification combined cycle (IGCC) systems. While traditional approaches to technolo-gy modeling and decision making may be appro-priate for well-established, commercial technology, they are inadequate as a basis for research planning for technologies in early stages of research and development. A probabilistic evaluation method-ology, and the required software capabilities, are developed for the ASPEN simulator. The method is applied to detailed case studies.
Polaronic and dressed molecular states in orbital Feshbach resonances

description: We consider the impurity problem in an orbital Feshbach resonance (OFR), with a single excited clock state $|e\uparrow\rangle$ atom immersed in a Fermi sea of electronic ground state $|g\downarrow\rangle$. We calculate the polaron effective mass and quasi-particle residue, as well as the polaron to molecule transition. By including one particle-hole excitation in the molecular state, we find significant correction to the transition point. This transition point moves toward the BCS side for increasing particle densities, which suggests that the corresponding many-body physics is similar to a narrow resonance.

An Analysis of the Broadband (22-3900 MHz) Radio Spectrum of HB3 (G132.7+1.3): The Detection of Thermal Radio Emission from an Evolved Supernova Remnant?

description: We present an analysis of the broadband radio spectrum (from 22 to 3900 MHz) of the Galactic supernova remnant (SNR) HB3 (G132.7+1.3). Published observations have revealed that a curvature is present in the radio spectrum of this SNR, indicating that a single synchrotron component appears is insufficient to adequately fit the spectrum. We present here a fit to this spectrum using a combination of a synchrotron component and a thermal bremsstrahlung component. We discuss properties of this latter component and estimate the ambient density implied by the presence of this component to be n \~ 10 cm^-3. We have also analyzed extracted X-ray spectra from archived {\it ASCA} GIS observations of different regions of HB3 to obtain independent estimates of the density of the surrounding interstellar medium (ISM). From this analysis, we have derived electron densities of 0.1-0.4 f^-1/2 cm^-3 for the ISM for the three different regions of the SNR, where f is the volume filling factor. By comparing these density estimates with the estimate derived from the thermal bremsstrahlung component, we argue that the radio thermal bremsstrahlung emission is emitted from a thin shell enclosing HB3. The presence of this thermal bremsstrahlung component in the radio spectrum of HB3 suggests that this SNR is in fact interacting with an adjacent molecular cloud associated with the HII region W3. By extension, we argue that the presence of thermal emission at radio wavelengths may be a useful tool for identifying interactions between SNRs and molecular clouds, and for estimating the ambient density near SNRs using radio continuum data.

description: My Dad, Brian Robert Thomas was born on 27.04.1927 in Barry, South Glamorgan. He was involved in the end of the Second World War, when he signed up for firstly the Navy, then the Marines. He said he was 'imaginative' about his true age to start with as he would have been too young to join up otherwise! Dad was a talented musician and played trumpet and cornet in The Royal Marines Band. He also drove trucks and other vehicles for the U.S. forces at a nearby base in South Wales. After crashing on an American motorbike, he spent months with his arm in plaster in a 'cage' until it mended. His claim to fame was once driving a staff car containing Winston Churchill's daughter in Holland.

description: This article presents findings from a large-scale quantitative assessment of online exchanges of copyrighted material on a college campus based on network data collected using deep packet inspection (DPI). We find that use of Peer-to-Peer (P2P) for the transfer of copyrighted content is widespread on campus, although observed P2P is declining. In a month-long monitoring period in Spring 2008, at least 40% of students living on campus were observed engaging in P2P, 70% of those were detected attempting to transfer copyrighted content, and each of the latter was observed transferring copyrighted titles at an average rate of 4 titles per day. Nevertheless, from Spring 2007 to Spring 2008, the daily percentage of detected P2P users fell 10%, and the daily percentage of users observed attempting to transfer copyrighted content out of those detected doing P2P fell 20%. These changes could be the result of decreasing use of P2P, or increasing use of encrypted P2P to evade detection. We also find that, given a couple weeks or more, current DPI technology identifies most users attempting to transfer copyrighted material, out of users whose P2P traffic it can detect. This shows that even if DPI does not detect every transfer of copyrighted material, it can effectively identify individuals who make these transfers, provided they do not use encryption. However, detection of copyrighted content is less accurate for video than for audio, so it may take far longer to identify individuals who use P2P to transfer copyrighted video but not copyrighted audio. Finally, to shed light on the impact of P2P on sales of content, we find that 22% of P2P users also purchase content from the iTunes Store (iTS), each buying on average about as much content as non- P2P users who purchase from the iTunes Store. This refutes the hypothesis that all P2P users view the ability to obtain free content from P2P as a complete substitute for paying for content. On the other hand, we also find that among iTs users, those who use P2P are somewhat more likely than those do not use P2P to access iTs only for the free samples.
