description: The amplitude for ordinary muon capture on the proton is evaluated, through the first four orders in the expansion parameter, in a manifestly Lorentz invariant form of baryon chiral perturbation theory. Expressions for the low energy constants in terms of physical quantities are obtained in each of the several renormalization schemes which have been proposed for forcing the relativistic approach to obey the same counting rules as obtained in heavy baryon chiral perturbation theory. The advantages and disadvantages of these schemes are discussed, using the muon capture results as an example, with the aim of gaining insight as to which scheme is preferable for practical calculations.

description: We propose a new type of regularization functional for images called oscillation total generalized variation (TGV) which can represent structured textures with oscillatory character in a specified direction and scale. The infimal convolution of oscillation TGV with respect to several directions and scales is then used to model images with structured oscillatory texture. Such functionals constitute a regularizer with good texture preservation properties and can flexibly be incorporated into many imaging problems. We give a detailed theoretical analysis of the infimal-convolution-type model with oscillation TGV in function spaces. Furthermore, we consider appropriate discretizations of these functionals and introduce a first-order primal-dual algorithm for solving general variational imaging problems associated with this regularizer. Finally, numerical experiments are presented which show that our proposed models can recover textures well and are competitive in comparison to existing state-of-the-art methods.

A hypervelocity star from the Large Magellanic Cloud

Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We study the acceleration of the star HE0437-5439, to hypervelocity and discuss its possible origin in the Large Magellanic Cloud (LMC). The star has a radial velocity of 723 km/s and is located at a distance of 61 kpc from the Sun. With a mass of about 8 Msun, the travel time from the Galactic centre is of about 100 Myr, much longer than its main sequence lifetime. Given the relatively small distance to the LMC (18 kpc), we consider it likely that HE0437-5439 originated in the cloud rather than in the Galactic centre, like the other hypervelocity stars. The minimum ejection velocity required to travel from the LMC to its current location within its lifetime is of about 500 km/s. Such a high velocity can only be obtained in a dynamical encounter with a massive black hole. We perform 3-body scattering simulations in which a stellar binary encounters a massive black hole and find that a black hole more massive than 1000 Msun is necessary to explain the high velocity of HE0437-5439. We look for possible parent clusters for HE0437-5439 and find that NGC 2100 and NGC 2004 are young enough to host stars coeval to HE0437-5439 and dense enough to produce an intermediate mass black hole able to eject an 8 Msun star with hypervelocity.

Multi-component plasmons in monolayer MoS$_2$ with circularly polarized optical pumping

description: By making use of circularly polarized light and electrostatic gating, monolayer molybdenum disulfide (ML-MoS$_2$) can form a platform supporting multiple types of charge carriers. They can be discriminated by their spin, valley index or whether they're electrons or holes. We investigate the collective properties of those charge carriers and are able to identify new distinct plasmon modes. We analyze the corresponding dispersion relation, lifetime and oscillator strength, and calculate the phase relation between the oscillations in the different components of the plasmon modes. All platforms in ML-MoS$_2$ support a long-wavelength $\sqrt{q}$ plasmon branch at zero Kelvin. In addition to this, for an $n$-component system, $n-1$ distinct plasmon modes appear as acoustic modes with linear dispersion in the long-wavelength limit. These modes correspond to out-of-phase oscillations in the different Fermion liquids and have, although being damped, a relatively long lifetime. Additionally, we also find new distinct modes at large wave vector that are stronger damped by intra-band processes.

description: Several researchers have recently advocated dynamic pricing mechanisms such as the smart market. This paper explores how dynamic state-dependent pricing and explicit congestion control can both be used to avoid and alleviate congestion. Dynamic pricing has significant advantages for heterogeneous traffic, although this paper demonstrates that this approach reduces raw throughput. It is shown that when propagation delay is non-trivial, as is the case in wide-area networks, a slow-reacting version of dynamic pricing is preferable. This paper also advocates the use of novel stream-oriented best-effort ATM services with which a stream's arrival process is declared to the network before transmission begins and then policed, although there are no performance guarantees and none of these best-effort streams are ever blocked. With this approach, it is possible to provide price incentives for applications to decrease traffic burstiness, and to reveal important information about their packet streams, making mechanisms like slow-reacting dynamic pricing more practical.

description: Modelling of multivariate densities is a core component in many signal processing, pattern recognition and machine learning applications. The modelling is often done via Gaussian mixture models (GMMs), which use computationally expensive and potentially unstable training algorithms. We provide an overview of a fast and robust implementation of GMMs in the C++ language, employing multi-threaded versions of the Expectation Maximisation (EM) and k-means training algorithms. Multi-threading is achieved through reformulation of the EM and k-means algorithms into a MapReduce-like framework. Furthermore, the implementation uses several techniques to improve numerical stability and modelling accuracy. We demonstrate that the multi-threaded implementation achieves a speedup of an order of magnitude on a recent 16 core machine, and that it can achieve higher modelling accuracy than a previously well-established publically accessible implementation. The multi-threaded implementation is included as a user-friendly class in recent releases of the open source Armadillo C++ linear algebra library. The library is provided under the permissive Apache~2.0 license, allowing unencumbered use in commercial products.

description: THE SECOND FIRE OF LONDON
DECEMBER 29th 1940'I looked at my watch; it was five-thirty. My eyes sought the grimy window, and I was looking once again at those huddled forms on the platform of the Elephant and Castle tube station. It was a piteous sight that met my eyes; sitting, lying, standing, with scarcely any room to breathe, from old men with bald, shiny heads to whimpering babes-in-arms, they waited there until the morning would see them for one more day living their humdrum existence at their office, home, or shop. It was the first time I had travelled by the London Underground since the war, but I promised myself that it would be the last.At length the train drew slowly out, and as I sat back, still stunned and rather sick at the horrible scene I had just witnessed, little did I realise that every turn of the wheels was taking me nearer to the place where, as unwilling but helpless onlooker, I was to watch HISTORY being made.I glanced up at the name-plate, as the train jolted to a standstill, and saw that it was Waterloo. "What's that guard shouting?" my mother asked. "All change here," father said. As we stepped out on to the platform, we were informed that a raid was in progress, and the platform was for shelter ticket holders only, but our railway tickets would see us through on any bus we took. I looked at my watch: it was six.We mounted the escalators and went out into the dark streets. It was the first time I had been out in a raid, and as we attempted to make our way along the road I felt too excited to be nervous.Suddenly, without warning, it happened. Boomp-boomp went the guns, pitter-patter fell the shrapnel. The gunfire sounded like the banging together of many dustbin lids, and I imagined, rather comfortingly, the Dorniers and Messerschmitts crashing to their doom. At first we saw only a dim red glow, becoming brighter as thousands of incendiaries burst into tiny fragments, showering their deadly fire over many innocent and unsuspecting buildings, which proceeded to burn furiously.With bombs and shrapnel bursting all around us, we reached the end of the road and boarded an unlit bus which was to take us to Oxford Circus. Slowly we drew away from the mass of burning girders and concrete, and I was not the only one to heave a sigh of relief when we crossed the river.The rest of the journey, except for one stop, owing to intense gunfire, passed uneventfully, though not monotonously.It is now February, 1941, and just as Wordsworth could never forget the
beauteous sight of many daffodils, I will never forget the horrible sight I witnessed when, through no choice of my own, I watched HISTORY BEING MADE.'FREDA GOTTLIEB (L.V, 1940).

Does ICT in schools affect residential adoption and adult utilization outside schools?

description: Policymakers around the world are considering whether to invest in putting information and communication technology (ICT) in schools, and how. While educational impact is likely to be the primary objective, such investments can also affect residential adoption and adult utilization of ICT in the communities, thereby reducing the digital divide. Using a census survey of Thailand for a time when ICT was available in roughly half of the nation’s schools, this study employs logistic regression and propensity score matching (PSM) to show that placing ICT in schools does have significant spill-over effects outside schools. This effect is larger for ICT in primary schools than secondary schools, and larger in schools with both Internet and computers than schools with just computers. The effects are observed in households of all incomes and educational levels. Considering these spill-over effects when allocating resources should lead to greater welfare gains for the amount of resources spent. The study also finds that there is a sizable portion of the adult population that chooses not to use ICT even after adopting this ICT in their households for their children, thereby eliminating any barriers to use related to cost and convenience. For this group, policy-makers should seek ways to decrease other impediments to ICT use, such as increasing ICT literacy through training.

description: My great-grandmother, Božena Jeřábková, was born and lived in Czechoslovakia (today the Czech Republic). She lost much of her youth to the Second World War and the Nazi occupation of her country. She shared her recollections of this period with us before she died in 2015 at the age of 89.Before the war ended in 1945, Nazi soldiers escorting a column of Russian POWs briefly stopped in her village, located almost two hours east of Prague. The soldiers warned residents not to interact with the prisoners, but some gave them food and cigarettes regardless. However, my great-grandmother was noticed giving something to a POW by a German guard, who threatened her at gunpoint. Fortunately, the situation did not escalate further. Before the march continued, the POW gave her a ring as a token of his gratitude. His eventual fate is unknown to us. She kept the ring for many years, though we are unsure of its present whereabouts.In September 1945, my great-grandparents relocated to a village in eastern Bohemia for my great-grandfather's work. My great-grandmother was pregnant with my grandmother at the time. She recalled how they slept with a loaded gun at their bedside due to either the rogue fascists or criminal partisans "” more commonly known as 'bandits' "” still at large in the surrounding countryside.
Massive star formation via high accretion rates and early disk-driven outflows

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We present an investigation of massive star formation that results from the gravitational collapse of massive, magnetized molecular cloud cores. We investigate this by means of highly resolved, numerical simulations of initial magnetized Bonnor-Ebert-Spheres that undergo collapse and cooling. By comparing three different cases - an isothermal collapse, a collapse with radiative cooling, and a magnetized collapse - we show that massive stars assemble quickly with mass accretion rates exceeding 10^-3 Msol/yr. We confirm that the mass accretion during the collapsing phase is much more efficient than predicted by selfsimilar collapse solutions, i.e. dM/dt ~ c^3/G. We find that during protostellar assembly the mass accretion reaches 20 - 100 c^3/G. Furthermore, we determined the self-consistent structure of bipolar outflows that are produced in our three dimensional magnetized collapse simulations. These outflows produce cavities out of which radiation pressure can be released, thereby reducing the limitations on the final mass of massive stars formed by gravitational collapse. Moreover, we argue that the extraction of angular momentum by disk-threaded magnetic fields and/or by the appearance of bars with spiral arms significantly enhance the mass accretion rate, thereby helping the massive protostar to assemble more quickly.

description: We study the Kitaev model on a finite-size square lattice with periodic boundary conditions in one direction and open boundary conditions in the other. Based on the fact that the Majorana representation of Kitaev model is equivalent to a brick wall model under the condition $t=Δ=μ$, this system is shown to support perfect Majorana bound states which is in strong localization limit. By introducing edge-mode fermionic operator and pseudo-spin representation, we find that such edge modes are always associated with maximal entanglement between two edges of the tube, which is independent of the size of the system.
Identification of nickel-vacancy defect in the photocurrent spectrum of diamond by means of \emph{ab initio} calculations

description: There is a continuous search for solid-state spin qubits operating at room temperature with excitation in the IR communication bandwidth. Recently we have introduced the photoelectric detection of magnetic resonance (PDMR) to read the electron spin state of nitrogen-vacancy (NV) center in diamond, a technique which is promising for applications in quantum information technology. By measuring photoionization spectra on a diamond crystal we found two ionization thresholds that were not reported before. On the same sample we also observed absorption and photoluminescence signatures that were identified in literature as Ni associated defects. We performed \emph{ab initio} calculation of the photo-ionization cross-section of the nickel split vacancy complex (NiV) and N-related defects in their relevant charge states and fitted the concentration of these defects to the measured photocurrent spectrum, which led to a surprising match between experimental and calculated spectra. This study enabled to identify the two unknown ionization thresholds with the two acceptor levels of NiV. Because the excitation of NiV is in infrared, the photocurrent detected from the paramagnetic NiV color centers is a promising way towards designing a novel type of electrically readout qubits.

description: My late father, Charles Cohen, was a musician; a percussionist who played the drums, xylophone, vibraphone and other percussion instruments. When he joined the RAF, he was in various bands. At the time this photo was taken in 1941, he was stationed at Linton-on-Ouse, where with four others, he formed a quintet that went under the name 'The Lintonaires'.This photo was taken at Rowntree in York where the chocolatier had a hall and where dances were arranged for staff. The Lintonaires performed for Rowntrees several times and they were each presented with this photo which bore at the foot of the original frame the inscription: 'Presented to The Lintonaires Dance Orchestra from Their Friends at Messrs Rowntrees, York, November 1941.Charles used to tell the story of how he had a date one night that clashed with a gig, (though not necessarily at Rowntree and not necessarily even when he was based at Linton-on-Ouse). He decided to go to the gig to start the dance but he then persuaded the remaining band members to cover for him whilst he snuck out to go on his date! Unfortunately, he was late returning and - he wasn't there for the drumroll that preceded the National Anthem. This left the rest of the band to improvise. Given there is little else that sounds like a drumroll, his absence was easily noticed!Charles was put on a charge and his punishment was to spend time serving drinks to officers in the officers' mess. As someone who never drank, they could not have put a less qualified person behind the bar

description: We explore the combined impact of sulfur vacancies and electronic interactions on the optical properties of monolayer MoS$_2$. First, we present a generalized Anderson-Hubbard Hamiltonian that accounts for both randomly distributed sulfur vacancies and the presence of dielectric screening within the material. Second, we parameterize this energy-dependent Hamiltonian from first-principles calculations based on density functional theory and the Green function and screened Coulomb (GW) method. Third, we apply a first-principles-based many-body typical medium method to determine the single-particle electronic structure. Fourth, we solve the Bethe-Salpeter equation to obtain the charge susceptibility $χ$ with its imaginary part being related to the absorbance $\mathcal{A}$. Our results show that an increased vacancy concentration leads to decreased absorption both in the band continuum and from exciton states within the band gap. We also observe increased absorption below the band gap threshold and present an expression, which describes Lifshitz tails, in excellent qualitative agreement with our numerical calculations. This latter increased absorption in the $1.0$--$2.5$\,eV makes defect engineering of potential interest for solar cell applications.

We also characterize the demographics of P2P users, the relative popularity of the material, and how the burden on the campus network varies over time. We found that at least 51% of students living on campus engaged in P2P, at least 42% attempted to transfer copyrighted material, and the mean number of copyrighted media titles whose transfer is attempted per week was at least 6 per monitored student. Some students use P2P legally, e.g. to transfer Linux software or non-copyrighted adult material, but we found no evidence that large numbers of students use P2P for these legal purposes and not to transfer copyrighted material. Students of all genders, ages, classes and majors engaged in file sharing, to the extent that demographics were not helpful in identifying likely file-sharers so as to target interventions. This study also provides lessons for those who would use DPI technology to reduce illegal use of P2P. If given enough weeks to observe, current technology is effective at identifying users who attempt to transfer copyrighted material, provided that their traffic is identifiable as P2P. Thus, DPI can be used to estimate the extent of piracy, and to notify individuals who may be violating copyright law. However, encryption is available and can be easily activated in most P2P clients. Once turned on, encryption prevents DPI from detecting whether transferred material is copyrighted, rendering it ineffective. If DPI is used for copyright enforcement that includes imposition of penalties, then P2P users or P2P developers may have the incentive to use encryption as a way of evading detection.

description: [transcription] Tout bien pesé, Monsieur et cher ami, votre opinion sur le sens de sedilia est préférable à la mienne, je l'admettrai, vous sentez que je ne vous ai fait à cet égard mes objections qu'avec la déférence que je vous dois comme à mon maître. J'aiécrit à M. de Valbelle, peut-être me donnera-t-il un dessin de tout ce qui a été trouvé, si cela est je vous en ferai part. Et tout de suite j'écrirai à l'académie car il convient que je luidonne de temps en temps quelque signe de vie. Si vous saviez que quelqu'un l'eut déjà informée de cette découverte vous me feriez plaisir de m'en instruire. Je me réjouisque vous ne désaprouviez pas ma conjecture sur dexiva, les grecs eux-même ont pris quelquefois [inscription grecque] pour la prospérité et se sont servis de ce mot en ce sens.

Plusieurs personnes m'ont dit que M. le Beau n'avait perdu sa chaire au collège royal et sa charge de secrétaire de l'académie que parce qu'il avait été du conseil de M. le duc d'Orléans, c'est ce que j'aiappellé des malheurs, c`en estunen effet que les affaires du temps, toujours indifférentes pour les savants et les philosophes leur fassent perdre leur rang, leur bien, leur existence, et les réduisent à n'être plus rien.

[fol. 162v] Le père Rivoire vient de m'apprendre par une lettre la découverte de la belle mosaïque de Vienne. Il me dit que ce pavé avait 25 pieds en carré mais il n'en reste que la moitié. Il croit aussi qu'elle appartenait à un temple de Neptune, il y a quelque apparence qu'il écrira quelque chose là-dessus pour le joindre à la dissertation, il laissera cet ouvrage à M. l'intendant qui ne pourra le faire imprimer qu'après le départ de M. Rivoire pour le Poitou. Ce départ est prochain.

J'ail'honneur d'être toujours avec les mêmes sentiments

Monsieur

Votre très humble et très obéissant serviteur

Calvet

description: We present a model of Fourier Power Density Spectrum (PDS) formation in accretion powered X-ray binary systems derived from the first principles of the diffusion theory. Timing properties of X-ray emission are considered to be a result of diffusive propagation of the driving perturbations in a bounded medium. We prove that the integrated power P_x of the resulting PDS is only a small fraction of the integrated power P_dr of the driving oscillations, which is distributed over the disk. The resulting PDS continuum is a sum of two components, a low frequency (LF) component which presumably originates in an extended accretion disk and a high frequency (HF) component which originates in the innermost part of the source (Compton cloud or corona). The LF PDS component has a power-law shape with index of 1.0-1.5 at higher frequencies (``red'' noise) and a flat spectrum below a characteristic (break) frequency (``white'' noise). This white-red noise (WRN) continuum spectrum holds information about the physical parameters of the bounded extended medium, diffusion time scale and the dependence law of viscosity vs radius. We apply our model of the PDS to a sample of RXTE and EXOSAT timing data from Cyg X-1 and Cyg X-2 which describes adequately the spectral transitions in these sources.

description: My grandad was slightly unusual, in that during the Second World War he was a railway signalman, and therefore needed to work in the signal boxes in Coventry. In fact, he worked in this job most of his life, and eventually died 1969, aged just 63.His name was Charles William Simmonds, known as Charlie to friends and acquaintances. He lived in the Broad Lane area of Coventry. He used to cycle to work, and frequently, on hearing the hum of enemy aircraft, had to throw himself and his bike into a ditch.One day, on his way to work, there had been a raid.A woman ran out of a house, shouting 'Help me! My house is on fire, my children are burning!' My grandad, as he was going to work, wasn't able to stop, and apologised quickly, before cycling on. The woman, not realising he was a signalman, hurled abuse at him.He said to my mum, his daughter, Cynthia, that he'd never felt so bad that day.My mum was baptised in 1935 in the original, old cathedral. She had many stories from the war. She remembered how there was a shelter under her stairs, and one across the street. One day, there was an air raid, and a woman ran with a baby to the shelter across the road. It was a neighbour, and it was a last-minute decision to go to the outside shelter. As she ran, a bomb exploded, bursting the child's eardrums, and killing it. The sad part is that the baby would have survived, if she'd stayed in her indoor shelter, under the stairs.On a lighter note, mum often recalled the food shortages. She was served up an egg once for breakfast. She turned her nose up at it. It was there again at lunch, then dinner. The following morning my Nan Ivy put the egg in front of my mum again, and reluctantly my mum ate it.All family members mentioned are no longer with us. My mum was the last to go in April 2022.

description: Charge exchange (CX) has emerged in X-ray emission modeling as a significant process that must be considered in many astrophysical environment--particularly comets. Comets host an interaction between solar wind ions and cometary neutrals to promote solar wind charge exchange (SWCX). X-ray observatories provide astronomers and astrophysicists with data for many X-ray emitting comets that are impossible to accurately model without reliable CX data. Here, we utilize a streamlined set of computer programs that incorporate the multi-channel Landau-Zener theory and a cascade model for X-ray emission to generate cross sections and X-ray line ratios for a variety of bare and non-bare ion single electron capture (SEC) collisions. Namely, we consider collisions between the solar wind constituent bare and H-like ions of C, N, O, Ne, Na, Mg, Al, and Si and the cometary neutrals H2O, CO, CO2, OH, and O. To exemplify the application of this data, we model the X-ray emission of Comet C/2000 WM1 (linear) using the CX package in SPEX and find excellent agreement with observations made with the XMM-Newton RGS detector. Our analyses show that the X-ray intensity is dominated by SWCX with H, while H2O plays a secondary role. This is the first time, to our knowledge, that CX cross sections have been implemented into a X-ray spectral fitting package to determine the H to H2O ratio in cometary atmospheres. The CX data sets are incorporated into the modeling packages SPEX and Kronos.

description: We estimate the sizeable cross section for deep exclusive electroproduction of an exotic $J^{PC}=1^{-+}$ hybrid meson in the Bjorken regime. The production amplitude scales like the one for usual meson electroproduction, {\it i.e.} as $1/Q^2$. This is due to the non-vanishing leading twist distribution amplitude for the hybrid meson, which may be normalized thanks to its relation to the energy momentum tensor and to the QCD sum rules technique. The hard amplitude is considered up to next--to--leading order in $α_{S}$ and we explore the consequences of fixing the renormalization scale ambiguity through the BLM procedure.

description: Over the past two decades, environmental regulations have transformed the design of new coalfired power plants. Requirements for the control of air pollutants, water pollutants and solid wastes have added considerably to plant complexity, while spurring the development of new, more innovative technology for the removal of pollutants before, during and after combustion. The availability of a larger number of options for meeting emission reduction requirements also has increased the need for systematic methods of evaluating and comparing process alternatives. In particular, there is now an increased need to assess the cost and performance of alternative power plant designs involving both conventional and advanced technologies. This paper describes an analytical model developed for the U.S. Department of Energy's Pittsburgh Energy Technology Center (DOE/PETC) under Contract No. DE-AC22-87PC79864. The model quantifies the performance and cost of power plant designs that involve user-specified combinations of pre-combustion, combustion, and post-combustion methods of environmental control. A unique feature of the Integrated Environmental Control Model (IECM) is the ability to characterize uncertainty in probabilistic terms, in contrast to conventional deterministic analysis. This capability offers special advantages in comparing advanced technologies at an early stage of . development with conventional systems where uncertainties are smaller. This paper reviews the current status of model development and presents an illustrative example of its use. Plans for further model development also are summarized

description: The quiescent periodic photometric modulations of two low-inclination cataclysmic variables observed in Kepler K2 Campaigns 0 and 1, KZ Gem and TW Vir, are investigated. A phase-correcting method was successfully used to detect the orbital modulations of KZ Gem and TW Vir and improve their orbital periods. The light curve morphologies of both CVs were further analyzed by defining flux ratios and creating colormaps. KZ Gem shows ellipsoidal modulations with an orbital period of 0.22242(1) day, twice the period listed in the updated RK catalogue (Edition 7.24). With this newly determined period, KZ Gem is no longer a CV in the period gap, but a long-period CV. A part of the quiescent light curve of TW Vir that had the highest stability was used to deduce its improved orbital period of 0.182682(3) day. The flat patterns shown in the colormaps of the flux ratios for KZ Gem demonstrate the stability of their orbital modulations, while TW Vir show variable orbital modulations during the K2 datasets. In TW Vir, the single versus double-peaked nature of the quiescent orbital variations before and after superoutburst may be related to the effect of the superoutburst on the accretion disk.
