description: The thermal efficiency of the kinesin cycle at stalling is presently a matter of some debate, with published predictions ranging from 0 (A. W. C. Lau, D. Lacoste and K. Mallick, Phys. Rev. Lett. 99, 158102 (2007); D. Lacoste, A. W. C. Lau and K. Mallick, Phys. Rev. E78, 011915 (2008)) to 100% (G. Oster and H. Wang, in Molecular Motors, edited by M. Schliwa (Wiley-VCH Verlag GmbH, Weinheim (2003), p. 207). In this note we attemp to clarify the issues involved. We also find an upper bound on the kinesin efficieny by constructing an ideal kinesin cycle to which the real cycle may be compared. The ideal cycle has a thermal efficiency of less than one, and the real one is less efficient than the ideal one always, in compliance with Carnot's theorem.

description: We investigate the behavior of the dc voltage drop in a periodically driven double barrier structure (DBS) sensed by voltages probes that are weakly coupled to the system. We find that the four terminal resistance $R_{4t}$ measured with the probes located outside the DBS results identical to the resistance measured in the same structure under a stationary bias voltage difference between left and right reservoirs. This result, valid beyond the adiabatic pumping regime, can be taken as an indication of the universal character of $R_{4t}$ as a measure of the resistive properties of a sample, irrespectively of the mechanism used to induce the transport.

description: In the quest for physically realizable quantum information science (QIS) primitives, self-assembled quantum dots (QDs) serve a dual role as sources of photonic (flying) qubits and traps for electron spin; the prototypical stationary qubit. Here we demonstrate the first observation of spin-selective, near background-free and transform-limited photon emission from a resonantly driven QD transition. The hallmark of resonance fluorescence, i.e. the Mollow triplet in the scattered photon spectrum when an optical transition is driven resonantly, is presented as a natural way to spectrally isolate the photons of interest from the original driving field. We go on to demonstrate that the relative frequencies of the two spin-tagged photon states are tuned independent of an applied magnetic field via the spin-selective dynamic Stark effect induced by the very same driving laser. This demonstration enables the realization of challenging QIS proposals such as heralded single photon generation for linear optics quantum computing, spin-photon entanglement, and dipolar interaction mediated quantum logic gates. From a spectroscopy perspective, the spin-selective dynamic Stark effect tunes the QD spin-state splitting in the ground and excited states independently, thus enabling previously inaccessible regimes for controlled probing of mesoscopic spin systems.

description: We consider the phase diagram of a spatially anisotropic 2D triangular antiferromagnet in a magnetic field. Classically, the ground state is umbrella-like for all fields, but we show that the quantum phase diagram is much richer and contains a 1/3 magnetization plateau, two commensurate planar states, two incommensurate chiral umbrella phases, and, possibly, a planar state separating the two chiral phases. Our analysis sheds light on several recent experimental findings for the spin-1/2 system Cs_2CuBr_4.

New fits to the reaction $γp\to K^+Λ$

name: Maxwell, Oren V.
name: Raue, Brian A.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The reaction $γp\to K^+Λ$ has been investigated over the center-of-momentum energy, $W$, range from threshold up to 2.2 GeV in a tree-level effective Lagrangian model that incorporates most of the well-established baryon resonances with spins equal to or below 5/2. Four less well-established nucleon resonances of higher mass are also included. The fitted parameters consist, for each resonance included, of the products of the coupling strengths at the electromagnetic and strong interaction vertices and, for the less-established nucleon resonances, the total decay width. For the well-established nucleon resonances, the energy and momentum dependence of the widths is treated within a dynamical model that is normalized to give the empirical decay branching ratios on the resonance mass shells. For the less-established resonances, the total decay width is treated as a single parameter independent of the reaction kinematics. The model is used to fit recent data for the unpolarized differential cross section (CLAS), the induced hyperon polarization asymmetry, $P$ (CLAS, GRAAL, and SAPHIR), the beam spin asymmetry, $Σ$ (LEPS), and the double polarization observables $C_x$ and $C_z$ (CLAS). Two different fits were obtained: one that incorporates SU(3) symmetry constraints on the Born contributions to the reaction amplitude and one in which these constraints are relaxed. Explicit numerical results are given only for the first fit since the two fits gave nearly identical results for the observables and the $χ^2$ per degree of freedom obtained with the second fit was only marginally better than that of the first fit ($<1%$ better). Results are presented for the fitted observables at several different energies and center-of-momentum (c.m.) frame kaon angles.

description: We study the renormalization of the properties of low lying charm and hidden charm scalar mesons in a nuclear medium, concretely of the D_{s0}(2317) and the theoretical hidden charm state X(3700). We find that for the D_{s0}(2317), with negligible width at zero density, the width becomes about 100 MeV at normal nuclear matter density, while in the case of the X(3700) the width becomes as large as 200 MeV. We discuss the origin of this new width and trace it to reactions occurring in the nucleus, while offering a guideline for future experiments testing these changes. We also show how those medium modifications will bring valuable information on the nature of the scalar resonances and the mechanisms of the interaction of D mesons with nucleons and nuclei.
What the Power Industry Has to Learn about Cyber Vulnerability Disclosure

Publisher: name: IEEE
Year: 2017

Newsletter
Although advanced metering infrastructures enable more dynamic generation, distribution and consumption, smart meters, wireless repeaters and routers must operate in physically unprotected environments and communicate with potentially hostile consumer systems. What is more, expanded bandwidth requirements tempt system designers to rely on non-dedicated and often un-trusted networks because of their lower costs. A combination of expanded cyber dependencies and greater public exposure will increase potential impacts from software vulnerabilities discovered within these systems. Thus, software vulnerability management is more problematic than ever.

description: We present the results of a deep (15 ~< r ~< 23), 20 night survey for transiting planets in the intermediate age open cluster M37 (NGC 2099) using the Megacam wide-field mosaic CCD camera on the 6.5m MMT. We do not detect any transiting planets among the ~1450 observed cluster members. We do, however, identify a ~ 1 R_J candidate planet transiting a ~ 0.8 Msun Galactic field star with a period of 0.77 days. The source is faint (V = 19.85 mag) and has an expected velocity semi-amplitude of K ~ 220 m/s (M/M_J). We conduct Monte Carlo transit injection and recovery simulations to calculate the 95% confidence upper limit on the fraction of cluster members and field stars with planets as a function of planetary radius and orbital period. Assuming a uniform logarithmic distribution in orbital period, we find that < 1.1%, < 2.7% and < 8.3% of cluster members have 1.0 R_J planets within Extremely Hot Jupiter (EHJ, 0.4 < T < 1.0 day), Very Hot Jupiter (VHJ, 1.0 < T < 3.0 days) and Hot Jupiter (HJ, 3.0 < T < 5.0 days) period ranges respectively. For 0.5 R_J planets the limits are < 3.2%, and < 21% for EHJ and VHJ period ranges, while for 0.35 R_J planets we can only place an upper limit of < 25% on the EHJ period range. For a sample of 7814 Galactic field stars, consisting primarily of FGKM dwarfs, we place 95% upper limits of < 0.3%, < 0.8% and < 2.7% on the fraction of stars with 1.0 R_J EHJ, VHJ and HJ assuming the candidate planet is not genuine. If the candidate is genuine, the frequency of ~ 1.0 R_J planets in the EHJ period range is 0.002% < f_EHJ < 0.5% with 95% confidence. We place limits of < 1.4%, < 8.8% and < 47% for 0.5 R_J planets, and a limit of < 16% on 0.3 R_J planets in the EHJ period range. This is the first transit survey to place limits on the fraction of stars with planets as small as Neptune.

Data collection in Advanced Metering Infrastructures (AMI) presents new opportunities for utilities but, at the same time, can compromise the privacy of electricity consumers. Data aggregation can alleviate this challenge by combining collected sensitive data into a single representation; however, the accountability of individual smart meter data can be lost because an attacker can falsify aggregates without being easily detected.
Administering regeneration in Wales: Policy and practice in a systems view
Creators: name: Paget, David
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Development studies not elsewhere classified

description: As a public service in the UK, area-based regeneration is a multi-objective and multi-disciplined approach aimed at developing more equal places. Complexity is a delivery challenge. There are problems with strategic coherence, public value and transparency. Mainstream public services are however improving their understanding of public strategy through embracing complexity. In Wales, with fifty years of experience of regeneration in the field, re-viewing delivery complexity is worthy of similar attention. In this study, an understanding of complexity and the management of local area regeneration re-thinks public service regeneration as a single system. A first orientation in Wales of regeneration in terms associated with a systems approach to managing change, usefulness to regeneration administration would be the eventual test. A new £100 million regeneration framework for Wales, Viable and Vibrant Places, provides the setting for operational action research, where policy and practice was examined in a systemic inquiry, over an extended period. With the EU referendum result offering new possibilities, Well-being legislation in Wales in early operation and some form of area-led regeneration reform in prospect, re-viewing regeneration in a single system was found to offer real-time and predictive administrative benefits to local area change: in understanding complexity, in the development of more purposeful, adaptable and transparent strategy, in the evaluation of attribution and sustainable regeneration integration.The aggregate qualities that make up excellence in delivery in regeneration policy and practice; ethical conduct, necessary knowledge and progressive measures, are appreciated in an arête model structure designed to be able to support improved regeneration conversations and delivery possibilities. Through systemic co-operation and collaboration regeneration leadership in Wales can, in a new era of change, advance citizen involvement and actor professionalism in the field, through new standards, and a plan that starts with imaginative action in conference and other proceedings.
Cosmic Rays and the Search for a Lorentz Invariance Violation

description: This is an introductory review about the on-going search for a signal of Lorentz Invariance Violation (LIV) in cosmic rays. We first summarise basic aspects of cosmic rays, focusing on rays of ultra high energy (UHECRs). We discuss the Greisen-Zatsepin-Kuz'min (GZK) energy cutoff for cosmic protons, which is predicted due to photopion production in the Cosmic Microwave Background (CMB). This is a process of modest energy in the proton rest frame. It can be investigated to a high precision in the laboratory, if Lorentz transformations apply even at factors $γ\sim O(10^{11})$. For heavier nuclei the energy attenuation is even faster due to photo-disintegration, again if this process is Lorentz invariant. Hence the viability of Lorentz symmetry up to tremendous gamma-factors - far beyond accelerator tests - is a central issue. Next we comment on conceptual aspects of Lorentz Invariance and the possibility of its spontaneous breaking. This could lead to slightly particle dependent ``Maximal Attainable Velocities''. We discuss their effect in decays, Cerenkov radiation, the GZK cutoff and neutrino oscillation in cosmic rays. We also review the search for LIV in cosmic gamma-rays. For multi TeV gamma-rays we possibly encounter another puzzle related to the transparency of the CMB, similar to the GZK cutoff. The photons emitted in a Gamma Ray Burst occur at lower energies, but their very long path provides access to information not far from the Planck scale. No LIV has been observed so far. However, even extremely tiny LIV effects could change the predictions for cosmic ray physics drastically. An Appendix is devoted to the recent hypothesis by the Pierre Auger Collaboration, which identifies nearby Active Galactic Nuclei - or objects next to them - as probable UHECR sources.

X-ray spectra from magnetar candidates. II Resonant cross sections for electron-photon scattering in the relativistic regime

Publisher: name: arXiv
Year: 2008

description: Recent models of spectral formation in magnetars called renewed attention on electron-photon scattering in the presence of ultra-strong magnetic fields. Investigations presented so far mainly focussed on mildly relativistic particles and magnetic scattering was treated in the non-relativistic (Thomson) limit. This allows for consistent spectral calculations up to a few tens of keVs, but becomes inadequate in modelling the hard tails (<200 keV) detected by INTEGRAL from magnetar sources. In this paper, the second in a series devoted to model the X-/soft gamma-ray persistent spectrum of magnetar candidates, we present explicit, relatively simple expressions for the magnetic Compton cross-section at resonance which account for Landau-Raman scattering up to the second Landau level. No assumption is made on the magnetic field strength. We find that sensible departures from the Thomson regime can bealready present at B ~5E12 G. The form of the magnetic cross section we derived can be easily implemented in Monte Carlo transfer codes and a direct application to magnetar spectral calculations will be presented in a forthcoming study.

title: The liability of the international multimodal transport operator for loss of or damage to the goods carried under a multimodal transport contract
Creators: name: Arbabi, Masoud
Publisher: name: University of Kent
Year: 2021

description: Multomodal transport of goods has increasingly developed from about three decades ago when container transport system came into existence. At the present time there is no operative convention to govern different legal aspects of the international multimodal transport of goods contracts including the multimodal transport operator's (MTO's) liability for loss of or damage to the goods. This thesis, therefore, attempts to consider the MTO's liability for loss of or damage to goods carried under a multimodal transport contract at the present time and in the future when the 1980 United Nations Multimodal Transport of Goods Convention comes into force. Since multimodal transport operations are mainly fulfilled through the use of containers, the MTO's liability is necessarily, therefore, considered in relation to the problem caused by container transport, i.e. the container-package problem, so that a special attention is given to that problem. To shed light on the container-package problem it was thought that the best way is to consider the courts' views in some countries which have a significant role in maritime and container transportation such as the U.S.A. and the U.K. Chapter one of this thesis deals with definition, history, aim and importance of multimodal transport of goods. The MTO's liability for loss of or damage to the goods at the present time has been considered in chapters two, three and four. Chapter five deals with some problems which can be particularly posed in relation to multimodal transport contracts. The MTO's liability for loss of or damage to the goods under the 1980 U.N. Multimodal Transport Convention is dealt with in chapter six. Chapter seven makes a comparison between the MTO's liability for loss or damage to the goods at the present time and when the 1980 U.N. Convention comes into force. This is followed by a conclusion at the end.

Universality of the hydrodynamic limit in AdS/CFT and the membrane paradigm

description: We show that at the level of linear response the low frequency limit of a strongly coupled field theory at finite temperature is determined by the horizon geometry of its gravity dual, i.e. by the "membrane paradigm" fluid of classical black hole mechanics. Thus generic boundary theory transport coefficients can be expressed in terms of geometric quantities evaluated at the horizon. When applied to the stress tensor this gives a simple, general proof of the universality of the shear viscosity in terms of the universality of gravitational couplings, and when applied to a conserved current it gives a new general formula for the conductivity. Away from the low frequency limit the behavior of the boundary theory fluid is no longer fully captured by the horizon fluid even within the derivative expansion; instead we find a nontrivial evolution from the horizon to the boundary. We derive flow equations governing this evolution and apply them to the simple examples of charge and momentum diffusion.

Subjects: cryptomarkets, darknet, violence, conflict resolution, escrow, feedback, vendor’s trustworthiness

description: In recent years, the Internet has become an important medium for promoting, distributing and retailing both ‘traditional’ and new drugs. This chapter discusses how the concept of using violence is transformed on darknet marketplaces that offer the technological infrastructure to buyers and sellers to process a drug transaction anonymously. By using a qualitative approach, the analysis focuses on alternative mechanisms regarding the use of violence as a means for settling disputes and for resolving conflicts. On cryptomarkets, the question of quality, quantity, shipping and payment of a product, which is potentially a source of conflict, needs to be addressed alternatively, because contact in person is not feasible. Instead, (1) a third party conflict resolution mechanism (centralised escrow), (2) paying prior to delivering the product (finalise early) and (3) the agreement of two out of three parties on releasing the payment (multi-signature escrow) constitute alternative mechanisms to the concept of violence as it has been described for conventional drug markets. Furthermore, face-to-face interactions are substituted with (4) the interplay of vendors, customers and market administrators using an elaborated feedback system, and (5) information discussed on various forums addressing a vendor’s trustworthiness, quality of a product, shipping, communication, and stealth.

description: The mid- to far-infrared emission of the outbursting FU Orionis objects has been attributed either to a flared outer disk or to an infalling envelope. We revisit this issue using detailed radiative transfer calculations to model the recent, high signal-to-noise data from the IRS instrument on the {Spitzer Space Telescope}. In the case of FU Ori, we find that a physically-plausible flared disk irradiated by the central accretion disk matches the observations. Building on our previous work, our accretion disk model with outer disk irradiation by the inner disk reproduces the spectral energy distribution between ~4000 angstroms to ~40 microns. Our model is consistent with near-infrared interferometry but there are some inconsistencies with mid-infared interferometric results. Including the outer disk allows us to refine our estimate of the outer radius of the outbursting, high mass accretion rate disk in FU Ori as ~ 0.5 AU, which is a crucial parameter in assessing theories of the FU Orionis phenomenon. We are able to place an upper limit on the mass infall rate of any remnant envelope infall rate to ~ 7e-7 Msun/yr assuming a centrifugal radius of 200 AU. The FUor BBW 76 is also well modelled by a 0.6 AU inner disk and a flared outer disk. However, V1515 Cyg requires an envelope with an outflow cavity to adequately reproduce the IRS spectrum. In contrast with the suggestion by Green et al., we do not require a flattened envelope to match the observations; the inferred cavity shape is qualitatively consistent with typical protostellar envelopes. This variety of dusty structures suggests that the FU Orionis phase can be present at either early or late stages of protostellar evolution.

Newsletter
Distributed Energy Resources (DER) encompasses distributed generation including combined heat and power, wind and photovoltaic systems, demand response, energy storage, vehicle-to-grid systems and microgrid. DER will have impacts on system operations and energy markets, which will require grid and energy market operations to embrace it. But what will be DER's impacts, and how can we model DER economics and adoption from the user point of view?

description: We have performed nonlinear ideal magnetohydrodynamic simulations of the long term evolution of a magnetized low-density "bubble" plasma formed by a radio galaxy in a stratified cluster medium. It is found that about 3.5% of the initial magnetic energy remains in the bubble after $\sim 8 \times 10^{9}$ years, and the initial magnetic bubble expansion is adiabatic. The bubble can survive for at least $8 \times 10^9$ years due to the stabilizing effect of the bubble magnetic field on Rayleigh-Taylor and Kelvin-Holmholtz instabilities, possibly accounting for "ghost cavities" as observed in Perseus-A\@. A filament structure spanning about 500 kpc is formed along the path of bubble motion. The mean value of the magnetic field inside this structure is $\sim 0.88$ $μ$G at $\sim8\times10^9$ years. Finally, the initial bubble momentum and rotation have limited influence on the long term evolution of the bubble.

Energy Storage in Deregulated Power Markets
Creators: Michael I. Henderson
Publisher: name: IEEE
Year: 2017

Newsletter
The large scale development of energy storage presents risks and opportunities. Storage devices can provide more efficient use of the transmission and distribution systems, facilitate the development of variable resources and improve the economic and environmental performance of electric power production resources. But increased reliance on storage will also affect the reliability of the power system and there will be a need for improved modeling of the net load forecasts, resource performance and transmission system performance.

description: We study the process of panspermia in Milky Way-like galaxies by modeling the probability of successful travel of organic compounds between stars harboring potentially habitable planets. To this end, we apply the modified habitability recipe of Gobat & Hong (2016) to a model galaxy from the MUGS suite of zoom-in cosmological simulations. We find that, unlike habitability, which only occupies narrow dynamic range over the entire galaxy, the panspermia probability can vary be orders of magnitude between the inner ($R, b = 1-4 {\rm kpc}$) and outer disk. However, only a small fraction of star particles have very large values of panspermia probability and, consequently, the fraction of star particles where the panspermia process is more effective than prebiotic evolution is much lower than from naïve expectations based on the ratio between panspermia probability and natural habitability.

description: We have proposed a novel numerical method to calculate accurately the physical quantities of the ground state with the tensor-network wave function in two dimensions. We determine the tensor network wavefunction by a projection approach which applies iteratively the Trotter-Suzuki decomposition of the projection operator and the singular value decomposition of matrix. The norm of the wavefunction and the expectation value of a physical observable are evaluated by a coarse grain renormalization group approach. Our method allows a tensor-network wavefunction with a high bond degree of freedom (such as D=8) to be handled accurately and efficiently in the thermodynamic limit. For the Heisenberg model on a honeycomb lattice, our results for the ground state energy and the staggered magnetization agree well with those obtained by the quantum Monte Carlo and other approaches.

description: A unitary design is a collection of unitary matrices that approximate the entire unitary group, much like a spherical design approximates the entire unit sphere. In this paper, we use irreducible representations of the unitary group to find a general lower bound on the size of a unitary t-design in U(d), for any d and t. We also introduce the notion of a unitary code - a subset of U(d) in which the trace inner product of any pair of matrices is restricted to only a small number of distinct values - and give an upper bound for the size of a code of degree s in U(d) for any d and s. These bounds can be strengthened when the particular inner product values that occur in the code or design are known. Finally, we describe some constructions of designs: we give an upper bound on the size of the smallest weighted unitary t-design in U(d), and we catalogue some t-designs that arise from finite groups.
