description: We study how turns and constrictions affect the resistive response of the superconducting wire after instant in time and local in space heating, which models the absorption of the single photon by the wire. We find that the presence of constriction favors detection of photons of various energies but the presence of turn increases only ability to detect relatively "low" energy photons. The main reason is that in case of constriction the current density is increased over whole length and width of the constriction while in case of the turn the current density is enhanced only near the inner corner of the turn. It results in inhomogeneous Joule heating near the turn and worsens the conditions for appearance of the normal domain at relatively small currents when the "high" energy photons already could create normal domain in straight part of the wire. We also find that the amplitude of the voltage pulse depends on the place where the photon is absorbed. It is the smallest one when photon is absorbed near the turn and it is the largest one when photon is absorbed near the constriction. This effect comes from the difference in resistance of constriction and the turn in the normal state from the resistance of the rest of the wire.

description: We investigated the impacts of the COVID-19 pandemic on the modality of formal cognitive assessments (in-person versus remote assessments). We created a web-based survey with 34 items and collected data from 114 respondents from a range of health care professions and settings. We established the proportion of cognitive assessments which were face-to-face or via video or telephone conferencing, both pre- and post-March 2020. Further, we asked respondents about the assessment tools used and perceived barriers, challenges, and facilitators for the remote assessment of cognition. In addition, we asked questions specifically about the use of the Oxford Cognitive Screen. We found that the frequency of assessing cognition was stable compared to pre-pandemic levels. Use of telephone and video conferencing cognitive assessments increased by 10% and 18% respectively. Remote assessment increased accessibility to participants and safety but made observing the subtleties of behaviour during test administration difficult. The respondents called for an increase in the availability of standardised, validated, and normed assessments. We conclude that the pandemic has not been detrimental to the frequency of cognitive assessments. In addition, a shift in clinical practice to include remote cognitive assessments is clear and wider availability of validated and standardised remote assessments is necessary.IMPLICATIONS FOR REHABILITATIONWe caution the wider use and interpretation of remote formal cognitive assessments due to lack of validated, standardised, and normed assessments in a remote format.Clinicians should seek out the latest validation and normative data papers to ensure they are using the most up to date tests and respective cut offs.Support is needed for individuals who lack knowledge/have anxiety over the use of technology in formal cognitive assessments We caution the wider use and interpretation of remote formal cognitive assessments due to lack of validated, standardised, and normed assessments in a remote format.

description: We study topological properties of the Bose-Hubbard model with repulsive interactions in a one-dimensional optical superlattice. We find that the Mott insulator states of the single-component (two-component) Bose-Hubbard model under fractional fillings are topological insulators characterized by a nonzero charge (or spin) Chern number with nontrivial edge states. For ultracold atomic experiments, we show that the topological Chern number can be detected through measuring the density profiles of the bosonic atoms in a harmonic trap.

The Future Of The Currituck Outer Banks
Creators: name: Owens, David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1980

description: One of the most controversial natural resource management issues in North Carolina over the past ten years has been the debate surrounding the future of the Currituck Outer Banks. As one of the last remaining undeveloped and privately owned barrier island stretches on the East Coast, this debate has taken on national significance. Unlike many similar controversies, planners have played a central role in this debate, and a comprehensive planning philosophy is being followed to determine the outcome. The resolution of this issue has not come about in traditional ways — there was neither a pitched battle between environmentalists and developers, nor an invisible decision by government bureaucrats. Rather, it was a test of the state's new comprehensive coastal management process. Some important lessons regarding the role of planners and government decision-making on complex resource management issues can be learned from this experience. The future of the Currituck Banks, which will not be finally determined for several more years, lies in how well these lessons have been learned and applied.
Bus Priority and Beyond in the Washington Metropolitan Region

description: On February 17, 2010, the National Capital Region Transportation Planning Board received a $58.8 million TIGER competitive grant for its planned regional priority bus network. This proposed network encompasses fourteen priority corridors and includes dedicated lanes, transit signal priority, queue-jump lanes, and a major regional transit center. This article describes the federal TIGER program, its application in the Washington metropolitan area, and the broader impacts of USDOT’s new mode-neutral approach to transportation funding. The TIGER grant program not only enabled implementation of a project that otherwise would have been difficult to fund via traditional channels, but it also empowered regional-level transportation planning that has had numerous benefits beyond the priority bus network grant.

description: RFID technology enables products and load units to be identified in the absence of a direct line of sight. In recent years, it has grown into one of the principal tools of identification used in industrial environments. For it to function properly, efficiently and reliably in such locations, factory planners require comprehensive integration of an RFID system. Although planning methods and tools for integrating RFID into existing production and logistical environments are available, it takes a great deal of time and expense to implement the procedures successfully. This is because logistics and production systems and processes need to be adapted to incorporate an RFID process, which discourages many companies from installing it in their production. Furthermore, to avoid identification problems in production and material flow processes, factory planners need substantial knowledge of the parameters that influence RFID. This paper presents a generic planning method which considers the conceptual design and implementation of RFID systems in an industrial environment from the beginning of the factory planning process. The aim of the method is to give factory planners and RFID experts a guideline on how to plan and implement RFID, by taking an interdisciplinary approach. After first reviewing current RFID planning methods, the paper presents a new six-phase planning method the aim of which is to enable experts in the industry to plan their production, logistics and RFID systems simultaneously, with due regard for the individual requirements of each system.

description: ICT or Information and Communication Technology has pervaded the fields of education.In recent years the term e-learning has emerged as a result of the integration of ICT in the education fields. Following the application this technology into teaching, some pitfalls have been identified and this have led to the Blended learning phenomenon.However the preference on this new method has been debated quite extensively.The aim of this paper is to investigate the advantages of blended learning over face to face instruction through reviews of related literature.The present survey revealed that blended learning is more favorable than pure e-learning and offers many advantages for learners like producing a sense of community or belonging.This study concludes that blended learning can be considered as an efficient approach of distance learning in terms of students' learning experience student-student interaction as well as studentinstructor interaction and is likely to emerge as the predominant education model in the future.

description: The blockchain technology represents a decentralized database that stores information securely in immutable data blocks. Regarding supply chain management, these characteristics offer potentials in increasing supply chain transparency, visibility, automation, and efficiency. In this context, first token-based mapping approaches exist to transfer certain supply chain events to the blockchain, such as the creation or assembly of parts as well as their transfer of ownership. However, the decentralized and immutable structure of blockchain technology also creates challenges. In particular, the scalability, storage capacity, and the special requirements for storage formats make it currently impossible to map all supply chain events unrestrictedly on the blockchain. As a first step, this paper identifies important supply chain events for different use cases combining blockchain technology and supply chain management. Secondly, the supply chain events are classified in terms of their expected technical properties and their relevance for the respective use case. Finally, the identified supply chain events are evaluated regarding their transferability to blockchain technology and a classification model is introduced.
Exploring Myths about Manufactured Housing: The Truth(s) behind One of America’s Least Understood Financial Markets

description: With the subprime mortgage crisis and the associated fall in housing values, it is more important than ever for affordable housing advocates to understand and educate the public about available low-cost housing options. Adam Rust argues that manufactured housing may be an avenue to wealth building even in this climate, but only if the truths are separated from the more familiar half-truths surrounding this housing choice. Data from the Home Mortgage Disclosure Act provides a snapshot of manufactured housing’s potential and pitfalls in different regions of the country under various financing scenarios.

description: We present a generalization of the complete intersection in products of projective space (CICY) construction of Calabi–Yau manifolds. CICY three-folds and four-folds have been studied extensively in the physics literature. Their utility stems from the fact that they can be simply described in terms of a ‘configuration matrix’, a matrix of integers from which many of the details of the geometries can be easily extracted. The generalization we present is to allow negative integers in the configuration matrices which were previously taken to have positive semi-definite entries. This broadening of the complete intersection construction leads to a larger class of Calabi–Yau manifolds than that considered in previous work, which nevertheless enjoys much of the same degree of calculational control. These new Calabi–Yau manifolds are complete intersections in (not necessarily Fano) ambient spaces with an effective anticanonical class. We find examples with topology distinct from any that has appeared in the literature to date. The new manifolds thus obtained have many interesting features. For example, they can have smaller Hodge numbers than ordinary CICYs and lead to many examples with elliptic and K3-fibration structures relevant to F-theory and string dualities.

description: To analyze the feasibility of and pain-related tolerance to a maximal cardiopulmonary exercise test (CPET), and the relationship between the aerobic capacity and central sensitization (CS) in patients with chronic low back pain (CLBP). An observational study, combining a cross-sectional and a prospective 24-hour follow-up was performed. Participants underwent a maximal CPET on a cycle ergometer and were assessed with three measures of CS (CS Inventory, quantitative sensory testing and heart rate variability). Before the CPET, immediately afterwards and 24 h after, the Pain Response Questionnaire (PRQ) was filled out. The CPET was considered feasible when >80% performed maximally, and tolerable when <20% reported relevant pain increase, body reactions and additional pain medication use in the PRQ. Multiple regression analyses were applied to assess the relationship between the aerobic capacity (VO2max) and CS measures, corrected for confounders. 74 patients with CLBP participated of which 30 were male, mean age was 40.4 years (SD: 12.4) and median VO2max was 23.9 ml/kg/min (IQR: 18.2–29.4). CPET was completed by 92%. No serious adverse events occurred. A relevant pain increase was reported in the upper legs by 40% immediately after CPET and by 28% 24 h afterwards, 27% reported body reactions after 24 h, and 22% increased pain medication use 24 h after CPET. Very weak and not significant relations (rpartial=−0.21 to 0.05; p > 0.10) were observed between aerobic capacity and CS measures. A maximal CPET is feasible in patients with CLBP. Most, but not all, tolerated it well. CS was not related to aerobic capacity.Implications for rehabilitationMaximal CPET is feasible in patients with CLBP and well tolerated by most patients.Maximal CPET can be safely applied to assess the aerobic capacity of patients with CLBP.Aerobic capacity is unrelated to central sensitization.Outcomes of a maximal CPET and the pain response to straining activity can be used to provide valid information for the decision-making of exercise therapy.

description: Petroleum derived polymers are based on a wide variety of basic chemical units, providing us with an even wider set of materials designed for countless applications. However, its ubiquitousness has generated environmental problems. Starches (mainly Amylose + Amylopectin), are natural products, non polluting, cheap and renewable, viable for biopolymer design. We analyze, using chemical computational tools, the basic atomistic features that make them such great alternatives to conventional sources.

description: In this paper we study the action of a generalization of the Binomial interpolated operator on the set of linear recurrent sequences. We find how the zeros of characteristic polynomials are changed and we prove that a subset of these operators form a group, with respect to a well-defined composition law. Furthermore, we study a vast class of linear recurrent sequences fixed by these operators and many other interesting properties. Finally, we apply all the results to integer sequences, finding many relations and formulas involving Catalan numbers, Fibonacci numbers, Lucas numbers and triangular numbers.

description: As a bright gamma-ray source, 3C 66A is of great interest to the high-energy astrophysics community, having a potential for placing cosmological constraints on models for the extragalactic background light (EBL) and the processes which contribute to this photon field. No firm spectroscopic redshift measurement has been possible for this blazar due to a lack of intrinsic emission and absorption features in optical spectra. We present new far-ultraviolet spectra from the Hubble Space Telescope/Cosmic Origins Spectrograph (HST/COS) of the BL Lac object 3C 66A covering the wavelength range 1132 to 1800 Angstroms . The data show a smooth continuum with intergalactic medium absorption features which can be used to place a firm lower limit on the blazar redshift of z>0.3347. An upper limit is set by statistically treating the non-detection of additional absorbers beyond z=0.3347, indicating a redshift of less than 0.41 at 99% confidence and ruling out z>0.444 at 99.9% confidence. We conclude by showing how the redshift limits derived from the COS spectra remove the potential for this gamma-ray emitting blazar to place an upper limit on the flux of the EBL using high energy data from a flare in October of 2009.

description: In this study, the in vitro bioavailability of rosehip infusion phenolics, mainly catechin, as a response to conventional and non-thermal treatments by combining gastrointestinal digestion and a Caco-2 cell culture model, was investigated. After application of thermal treatment (TT, 85 °C/10 min), high pressure (HPP, 600 MPa/5 min) or pulsed electric field (PEF, 15 kJ/kg) processing, all samples were subjected to simulated gastrointestinal digestion. Then, the amount of maximum non-toxic digest ratio was determined by the cytotoxicity sulforhodamine B (SRB) assay. Next, Caco-2 cells were exposed to 1:5 (v/v) times diluted digests in order to simulate the transepithelial transportation of catechin. Results showed that non-thermally processed samples (5.19 and 4.62% for HPP and PEF, respectively) exhibited greater transportation across the epithelial cell layer compared to than that of the TT-treated sample (3.42%). The present study highlighted that HPP and PEF, as non-thermal treatments at optimized conditions for infusions or beverages, can be utilized in order to enhance the nutritional quality of the final products.

description: We address the question what physical resources are required and sufficient to store classical information. While there is no lower bound on the required energy or space to store information, we find that there is a nonzero lower bound for the product (P = ) of these two resources. Specifically, we prove that any physical system of mass m and d degrees of freedom that stores S bits of information will have lower bound on the product P that is proportional to d^2/m (exp(S/d)-1)^2. This result is obtained in a non-relativistic, quantum mechanical setting and it is independent from earlier thermodynamical results such as the Bekenstein bound on the entropy of black holes.

description: This work aims to disentangle the morphological, kinematic, and chemical components of the nebula M1-67 to shed light on its process of formation around the central Wolf-Rayet (WR) star WR124. We have carried out integral field spectroscopy observations over two regions of M1-67, covering most of the nebula in the optical range. Maps of electron density, line ratios, and radial velocity were created to perform a detailed analysis of the two-dimensional structure. We studied the physical and chemical properties by means of integrated spectra selected over the whole nebula. Photoionization models were performed to confirm the empirical chemical results theoretically. In addition, we analysed infrared spectroscopic data and the MIPS 24micron image of M1-67 from Spitzer. We find that the ionized gas of M1-67 is condensed in knots aligned in a preferred axis along the NE-SW direction, like a bipolar structure. Both electron density and radial velocity decrease in this direction when moving away from the central star. From the derived electron temperature, Te~8200 K, we have estimated chemical abundances, obtaining that nitrogen appears strongly enriched and oxygen depleted. From the last two results, we infer that this bipolarity is the consequence of an ejection of an evolved stage of WR124 with material processed in the CNO cycle. The infrared study has revealed that the bipolar axis is composed of ionized gas with a low ionization degree that is well mixed with warm dust and of a spherical bubble surrounding the ejection at 24micron. Taking the evolution of a 60 Mo star and the temporal scale of the bipolar ejection into account, we propose that the observed gas was ejected during an eruption in the luminous blue variable. The star has entered the WR phase recently without apparent signs of interaction between WR-winds and interstellar material.

description: The purpose of the current review is to synthesize the evidence of patients’ perspectives of recovery after hip fracture across the care continuum. A systematic search was conducted, focusing on qualitative data from hip fracture patients. Screening, quality appraisal, and a subset of articles for extraction were completed in duplicate. Themes were generated using a thematic synthesis of data from original studies. Fourteen high-quality qualitative studies were included. Four review themes were identified: recovery as participation, feelings of vulnerability, driving recovery, and reliance on support. Patients considered recovery as a return to pre-fracture activities or “normal” enabling independence. Feelings of vulnerability were observed irrespective of the time since hip fracture and only diminished when recovery of function and activities enabled participation in valued activities, e.g., outdoor mobility. Participants expressed a desire to engage in recovery with realistic expectations and the benefits of meaningful feedback reported. While reliance on healthcare professionals decreased towards a later stage of recovery, reliance on social support persisted until recovery was perceived to have been achieved. Patient perspectives highlighted hip fracture as a major life event requiring health professional and social support to overcome feelings of vulnerability and enable active engagement in recovery.IMPLICATIONS FOR REHABILITATIONRehabilitation professionals should ensure expectations and goals are set early in the recovery process.Rehabilitation professionals should ensure goals set with patients are tailored to the individual’s pre-fracture activities or “normal” promoting independence.Rehabilitation professionals should monitor goals ensuring they are providing support, motivation, and managing expectations across the care continuum.Rehabilitation professionals should address patients’ feelings of vulnerability, particularly in the absence of social support, and ensure appropriate ongoing input to maximize recovery.

description: We study center-of-mass oscillations of a dipolar Bose-Einstein condensate in the vicinity of a superconducting surface. We show that the magnetic field of the magnetic dipoles induces eddy currents in the superconductor, which act back on the Bose-Einstein condensate. This leads to a shift of its oscillation frequency and to an anharmonic coupling of the Bose-Einstein condensate with the superconductor. The anharmonicity creates a coupling to one of the collective modes of the condensate that can be resonantly enhanced, if the parameters of the condensate are chosen properly. This provides a new physical mechanism to couple a Bose-Einstein condensate and a superconductor which becomes significant for 52Cr, 168Er or 164Dy condensates in superconducting mircotraps.

description: We point out that supersymmetric gauged flavor models provide a realization of R-parity violation (RPV) that is natural in the sense that it does not lead to catastrophic proton decay for natural values of parameters in the theory. Within specific realizations of the idea, the relative strengths of the $ΔB=1$ $u^c d^c d^c$ type RPV operators can be predicted. In particular, we present examples of gauged flavor models where RPV couplings depend on quark masses as $(m_{u_i} m_{d_j} m_{d_k} / m_t^3)^n$ where $n=1$ or $n= 1/2$. Some phenomenological implications of these models are discussed.

A Peak Load Pricing Policy for North Carolina Utilities

Year: 1977

description: In the early 1970s North Carolina electric utility companies planned to embark on construction projects for new plants costing billions of dollars. But, for the first time in the history of the state, power firm policies fell upon turbulent waters. Soaring electric rates had resulted in a tide of consumer outrage. Legislative efforts delayed the companies from sailing their original courses. Questions were being raised about utility pricing policies. In 1975, the North Carolina legislature adopted a measure by Senator McNeill Smith to require the state Utilities Commission to hold public hearings on peak load pricing and the future needs for electricity in the state. After the December, 1975 hearings, the Commission ordered the utilities to submit plans to implement this form of pricing. With peak load pricing, a consumer is charged a rate based upon the time of day he uses the electricity. This system charges a lower rate for off-peak use to encourage electricity consumption at off-peak "With peak load pricing, a consumer is charged a rate based upon the time of day he uses electricity." periods. Advocates of peak load pricing, sometimes called time of day or marginal cost pricing, claim there could be an immediate reduction in average monthly bills and that construction programs for new generating capacity to meet peak demand would be delayed for a significant period in the future.

Of Ships and Seaweed

description: I walked into the office of the consensus All-State planning director the other day. I couldn't help but notice two signs pinned to the wall over his work table. One said "Seaweed" and the other "Ships." There were several reports and plans arranged under each sign. My curiousity aroused, I asked about the significance of the signs. The planning director said: "It's really quite simple. We have two sections in our department, with quite different ways of doing things. The Seaweed Section gets all the assignments that are ill-conceived, undesirable, and that generally we would like to see fall by the wayside . . .You know, the special election-year report for Commissioner Fusspot and that sort of thing. The Ship Section, you may have guessed, gets our important work, the stuff we would really like to see get implemented and that will have a lasting, positive impact on the community."
WSRT observations and surface photometry of two unusual spiral galaxies

description: We discuss the results of a mass decomposition of two spiral galaxies, NGC 6824 and UGC 11919. In a previous analysis of the Hyperleda catalog, the galaxies were identified as having a peculiar dynamical $M/L$. The aim of this study is to confirm or disprove the preliminary findings, indicating a non-standard stellar initial mass function (IMF) for the galaxies. The surface photometry in B, V, and R bands was carried out with the Apache Point 0.5-m telescope and the \ion{H}{I} data cubes were obtained with the Westerbork Synthesis Radio Telescope (WSRT). Photometric profiles were decomposed into bulge and exponential disk components. Using the obtained \ion{H}{I} data cubes, rotation curves of both galaxies were constructed. Employing the photometric profiles, the mass distribution of the galaxies was decomposed into mass components: bulge, stellar disk, gas, and pseudo-isothermal dark halo. We conclude that NGC 6824 possesses a stellar disk with mass-to-light ratio $(M/L_B)_{\rm disk} = 2.5$, in agreement with its color $(B-V)_0$. On the contrary, UGC 11919 appears to have a very lightweight disk. Its dynamically estimated mass corresponds to a low stellar disk mass-to-light ratio $(M/L_B)_{\rm disk} \approx 0.5$. Under standard assumptions, this ratio does not agree with the relatively red color of the disk, while a bottom light stellar initial mass function is needed to explain the observations.

description: We present a research roadmap of a Planetary Nervous System (PNS), capable of sensing and mining the digital breadcrumbs of human activities and unveiling the knowledge hidden in the big data for addressing the big questions about social complexity. We envision the PNS as a globally distributed, self-organizing, techno-social system for answering analytical questions about the status of world-wide society, based on three pillars: social sensing, social mining, and the idea of trust networks and privacy-aware social mining. We discuss the ingredients of a science and a technology necessary to build the PNS upon the three mentioned pillars, beyond the limitations of their respective state-of-art. Social sensing is aimed at developing better methods for harvesting the big data from the techno-social ecosystem and make them available for mining, learning and analysis at a properly high abstraction level.Social mining is the problem of discovering patterns and models of human behaviour from the sensed data across the various social dimensions by data mining, machine learning and social network analysis. Trusted networks and privacy-aware social mining is aimed at creating a new deal around the questions of privacy and data ownership empowering individual persons with full awareness and control on own personal data, so that users may allow access and use of their data for their own good and the common good. The PNS will provide a goal-oriented knowledge discovery framework, made of technology and people, able to configure itself to the aim of answering questions about the pulse of global society. Given an analytical request, the PNS activates a process composed by a variety of interconnected tasks exploiting the social sensing and mining methods within the transparent ecosystem provided by the trusted network.

description: The experimentally obtained (Venkataraman {\em et al}. \cite{latha}) cosine squared relation of electronic conductance in a biphenyl molecule is verified theoretically within a tight-binding framework. Using Green's function formalism we numerically calculate two-terminal conductance as a function of relative twist angle among the molecular rings and find that the results are in good agreement with the experimental observation.

Moving contact line of a volatile fluid

description: Interfacial flows close to a moving contact line are inherently multi-scale. The shape of the interface and the flow at meso- and macroscopic scales inherit an apparent interface slope and a regularization length, both called after Voinov, from the dynamical processes at work at the microscopic level. Here, we solve this inner problem in the case of a volatile fluid at equilibrium with its vapor. The evaporative/condensation flux is then controlled by the dependence of the saturation temperature on interface curvature -- the so-called Kelvin effect. We derive the dependencies of the Voinov angle and of the Voinov length as functions of the substrate temperature. The relevance of the predictions for experimental problems is finally discussed.
