description: The Swift X-ray Telescope (XRT) focal plane camera is a front-illuminated MOS CCD, providing a spectral response kernel of 144 eV FWHM at 6.5 keV. We describe the CCD calibration program based on celestial and on-board calibration sources, relevant in-flight experiences, and developments in the CCD response model. We illustrate how the revised response model describes the calibration sources well. Loss of temperature control motivated a laboratory program to re-optimize the CCD substrate voltage, we describe the small changes in the CCD response that would result from use of a substrate voltage of 6V.

description: We present the stellar and gas kinematics of a sample of 18 nearby late-type spiral galaxies (Hubble types ranging from Sb to Sd), observed with the integral-field spectrograph SAURON at the 4.2-m William Herschel Telescope. SAURON covers the spectral range 4800-5380 A, allowing us to measure the Hbeta, Fe, Mgb absorption features and the emission in the Hbeta line and the [OIII], and [NI] doublets over a 33x41 arcsec field of view. The maps cover the nuclear region of these late-type galaxies and in all cases include the entire bulge. In many cases the stellar kinematics suggests the presence of a cold inner region, as visible from a central drop in the stellar velocity dispersion. The ionised gas is almost ubiquitous and behaves in a complicated fashion: the gas velocity fields often display more features than the stellar ones, including wiggles in the zero-velocity lines, irregular distributions, ring-like structures. The line ratio [OIII]/Hbeta often takes on low values over most of the field, probably indicating a wide-spread star formation.

description: Objective: To investigate the predictive factors associated with physical impairment among older patients with type 2 diabetes mellitus (T2DM) in Japan and to examine the potential impact of physical impairment on patient-reported health outcomes in this population. Methods: A cross-sectional analysis was conducted using patient-reported data from the 2012-2014 Japan National Health and Wellness Survey. Physical impairment was measured using the Physical Component Summary (PCS) score of the Short-Form 36-Item Health Survey (SF-36) three-component model (using Japanese norms). Older T2DM patients (≥65 years old; n = 1511) were dichotomized into physically impaired (PCS ≤25th percentile; n = 378) and non-physically impaired (PCS >25th percentile; n = 1,133). Work productivity (absenteeism, presenteeism, and overall work impairment), activity impairment, and healthcare resource utilization were compared between these groups. Results: Age, female sex, low and high body mass index (BMI), diabetes-related complications, cardiovascular events, unawareness of having hypoglycemic events in the past 3 months, and lack of regular exercise were significant factors associated with physical impairment in multivariable analysis. The physically impaired group reported significantly more regular outpatient visits (13.48 vs. 10.16, respectively, P P = 0.005), greater presenteeism (27.8% vs. 12.2%, P = 0.001), overall work impairment (30.0% vs. 13.0%, P = 0.001), and overall activity impairment (39.5% vs. 17.2%, P<0.001) than the non-physically impaired group after adjusting for covariates. Conclusions: This study identified age, BMI, diabetes-related comorbidities, history of cardiovascular events, and lack of exercise as key predictors associated with physical impairment in older patients with T2DM in Japan, which predicted low work productivity as well as activity impairment. This study provides support that physical impairment in patients with T2DM may lead to low work productivity and activity impairment.
Effcient Implementation and H∞ On-Blade Control Design of the EC-145 Rotor for Vibration Reduction
Creators: name: Jahaz Alotaibi

Year: 2020
Subjects: Uncategorized

description: This thesis presents the development and implementation of a comprehensive helicopter active rotor model, and the design of robust control laws operating on a wide region of the cruise flight envelope for reduction of vibration originated by the main rotor. The vibration mitigation methods are tested on a hingeless analytical rotor model of the four-blade Airbus EC-145 helicopter demonstrator, with the main rotor blades mounted with active trailing-edge flaps. The model was implemented in MATLAB and Simulink and has been validated against the more comprehensive model CAMRAD II (Comprehensive Analytical Model of Rotorcraft Aerodynamics and Dynamics) and flight test data. The integrals of blade-element aerodynamic forces were solved analytically and implemented in closed-form for improved accuracy and computational efficiency. The design of a single set of control algorithms can provide vibration reduction for hover, 20, 40, 60, 80 and 100 knots forward flight. The ability to obtain a single set of control laws offer the benefits of reduced processing power and relaxation of implementation requirements in practical scenarios while guaranteeing very good performance levels. To enable the application of H1 control design methods, system identification tools are applied to extract Linear-Time-Invariant models at the considered flight conditions. Two types of vibration reduction approaches are considered: i) The first approach takes into account the 4=rev vertical force component only, which is the dominant component in the vibration signature. ii) The second approach, being more general, considers all six force and moment vibration component at the rotor hub. The first approach provided around 47.05% vibration reduction on average, while the second improves the average vibration level to 68.07%. We discuss in the thesis benefits and drawbacks of each approach in terms of robustness properties, performance and implementation requirements.

description: The Soft X-ray Spectrometer (SXS) on board \textit{Hitomi}, with the unprecedented resolving power of R$\sim$1250, allowed the detection of members of the Fe XXV \ka\ complex emission spectra from the center of the Perseus Cluster. In this paper, we introduce a novel method of measuring the column density using the optically thin (Case A) to optically thick (Case B) transition for one- and two-electron systems. We compare the Fe XXV K$α$ line ratios computed with CLOUDY with that from the \textit{Hitomi} observations in the outer region of the Perseus core using collision strengths from different atomic datasets, and obtain good agreement. We also show the effect of turbulence on Fe XXV K$α$ line ratios and interplay between column density and metallicity. Besides, we discuss the atomic number dependence of transition probabilities for allowed and non-allowed transitions, which causes the highly charged He-like systems, such as Fe XXV, to behave fundamentally differently from He I.

description: For traditional library collections, archivists can select a representative sample from a collection and display it in a featured physical or digital library space. Web archive collections may consist of thousands of archived pages, or mementos. How should an archivist display this sample to drive visitors to their collection? Search engines and social media platforms often represent web pages as cards consisting of text snippets, titles, and images. Web storytelling is a popular method for grouping these cards in order to summarize a topic. Unfortunately, social media platforms are not archive-aware and fail to consistently create a good experience for mementos. They also allow no UI alterations for their cards. Thus, we created MementoEmbed to generate cards for individual mementos and Raintale for creating entire stories that archivists can export to a variety of formats.

description: To characterize burden of migraine in prevention-eligible patients compared with prevention non-eligible patients in the United States (US). Receipt of preventive therapy was also examined among prevention-eligible patients. This retrospective study utilized data from the 2017 US National Health and Wellness Survey linked with medical and pharmacy claims. Patients aged ≥18 years who self-reported experiencing migraine and had confirmed evidence of migraine (≥1 medical or pharmacy claim) were included. Prevention eligibility was based on number of headache days in the past 30 days (prevention-eligible: ≥4 and prevention non-eligible: <4). Descriptive statistics summarized study variables; bivariate and multivariable analyses were conducted to examine the association of prevention-eligibility status with outcomes. Analyses included 450 patients, 291 (65%) prevention-eligible, and of these 56 (19%) received preventive therapy. Overall, patients were 42.98 ± 14.51 years old; 84% were female. Prevention-eligible patients reported significantly more migraine headache days in the past 6 months (29.27 ± 37.96 vs 8.61 ± 7.88), had lower mental component summary scores (35.80 ± 2.73 vs 37.90 ± 2.96), and more presenteeism (47.30 ± 2.98% vs 37.90 ± 2.60%), overall work impairment (46.30 ± 2.87% vs 37.90 ± 2.55%) and activity days missed due to migraine (8.16 ± 3.05 vs 3.82 ± 1.58) than prevention non-eligible patients (all pp=.002) and activity days lost due to migraine (18.39 ± 28.08 vs 10.69 ± 21.43, p=.015) than those not receiving preventive therapy. Prevention-eligible patients experience greater burden due to migraine, including more headache days, worse health-related quality-of-life, and greater work and activity impairment than prevention non-eligible patients.

description: High Rydberg states of nitric oxide (NO) with principal quantum numbers between 40 and 100 and lifetimes in excess of 10 $μ$s have been prepared by resonance enhanced two-color two-photon laser excitation from the X $^2Π_{1/2}$ ground state through the A $^2Σ^+$ intermediate state. Molecules in these long-lived Rydberg states were detected and characterized 126 $μ$s after laser photoexcitation by state-selective pulsed electric field ionization. The laser excitation and electric field ionization data were combined to construct two-dimensional spectral maps. These maps were used to identify the rotational states of the NO$^+$ ion core to which the observed series of long-lived hydrogenic Rydberg states converge. The results presented pave the way for Rydberg-Stark deceleration and electrostatic trapping experiments with NO, which are expected to shed further light on the decay dynamics of these long-lived excited states, and are of interest for studies of ion-molecule reactions at low temperatures.

Different polarization can be achieved in the two output channels from an originally totally unpolarized incoming spin state, very much like in a Stern-Gerlach apparatus. We determine the relevant parameters such that the device has unit efficiency.

In this paper, we describe how to combine several existing tools with web archive holdings to perform news analysis and visualization of the "biggest story" for a given date. StoryGraph clusters news articles together to identify a common news story. Hypercane leverages ArchiveNow to store URLs produced by StoryGraph in web archives. Hypercane analyzes these URLs to identify the most common terms, entities, and highest quality images for social media storytelling. Raintale then uses the output of these tools to produce a visualization of the news story for a given day. We name this process SHARI (StoryGraph Hypercane ArchiveNow Raintale Integration).

A Most Dangerous Place Finding the Non-Combatant within the Greek Polis
Creators: name: Evans, Richard J. G.
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: This thesis demonstrates the existence of rules concerning noncombatancy (legal inviolability in inter-state conflict) within ancient Greek international law. By examining three defined groups – kērukes (heralds), presbeis (ambassadors), and proxenoi – their legal inviolability in warfare is used to illustrate that the Greek poleis possessed a widely agreed cultural legal standard of noncombatancy for each of these groups under certain contexts and circumstances. This standard naturally varied for each group. The contexts of each group’s inviolability are brought out in individual chapters, which explores the idea and concept of their noncombatancy over the longue durée from the eighth to the first century BC. Each group’s inviolability is examined in further detail and cross-compared within the final discussion chapter to examine the nature of noncombatancy as a legal idea in Greek inter-state conflict.This thesis also discusses the status of the larger group of civilians (incapacitated or elderly men, women and children) that resided within poleis, contrasting them with the legal protections afforded to the case-study groups. The conclusion from this examination is that this wider group of civilians did not possesses any customary or positive legal protection during warfare, thus relying on spatial asylia (the inviolability of a certain location) if they wished to have any protection.The deeper philosophical and sociological implications for this situation are explored in the final chapter, too, which suggests that civilians sensu lato ‘in a wide sense’ never gained protection as they have today because of the economic incentives behind Greek warfare, and its total nature in terms of the culpability of the whole polis community. The conclusion from this is that while the Greeks certainly did have laws of war regarding non-combatants, they were neither the ones we expected, nor the ones we might have wanted to find.
The fully self-consistent quasiparticle random phase approximation and its application to the isobaric analog resonances

Year: 2005
Subjects: subject: Nuclear Theory (nucl-th)

description: A microscopic model aimed at the description of charge-exchange nuclear excitations along isotopic chains which include open-shell systems, is developed. It consists of quasiparticle random phase approximation (QRPA) made on top of Hartree-Fock-Bardeen-Cooper-Schrieffer (HF-BCS). The calculations are performed by using the Skyrme interaction in the particle-hole channel and a zero-range, density-dependent pairing force in the particle-particle channel. At variance with the (many) versions of QRPA which are available in literature, in our work special emphasis is put on the full self-consistency. Its importance, as well as the role played by the charge-breaking terms of the nuclear Hamiltonian, like the Coulomb interaction, the charge symmetry and charge independence breaking (CSB-CIB) forces and the electromagnetic spin-orbit, are elucidated by means of numerical calculations of the isobaric analog resonances (IAR). The theoretical energies of these states along the chain of the Sn isotopes agree well with the experimental data in the stable isotopes. Predictions for unstable systems are presented.

description: Village planning is an important part of land spatial planning and an important measure to implement rural strategy. At present, the preparation of village planning is not complete, and the establishment of technical guidelines is not systematic. Therefore, the course of the development of domestic village planning and the common problems are analyzed. Taking Wentang Village, Yichun City, Jiangxi Province as an example, this paper considers the contents of land use, industrial development, residential layout, ecological environment renovation and historical and cultural inheritance from the perspective of multi-plan integration. This paper discusses the establishment method of the new round of village planning, and puts forward the safeguard measures for the implementation of the planning, so as to provide reference for the establishment of the new round of village planning.

description: This study investigates the stability of higher-dimensional singly rotating Myers-Perry-de Sitter (MP-dS) black holes against scalar field perturbations. The phase spaces of MP-dS black holes with one spin parameter are discussed. Additionally, the quasinormal modes (QNMs) of MP-dS black holes are calculated via the asymptotic iteration method and sixth-order Wentzel-Kramers-Brillouin approximation. For near-extremal MP-dS black holes, the event horizon may be considerably close to the cosmological horizon. In such cases, the Pöschl-Teller technique yields an accurate analytic formula for the QNMs. It is found that when the spin parameter of a black hole increases, the scalar perturbation modes oscillate at higher frequencies and decay faster. Furthermore, the MP-dS black hole with a single rotation is found to be stable under perturbation.

description: The possibility of the pion condensation phenomenon in cold and electrically neutral dense baryonic matter is investigated in $β$-equilibrium. For simplicity, the consideration is performed in the framework of a NJL model with two quark flavors at zero current quark mass and for rather small values of the baryon chemical potential, where the diquark condensation might be ignored. Two sets of model parameters are used. For the first one, the pion condensed phase with finite baryon density is realized. In this phase both electrons and the pion condensate take part in the neutralization of the quark electric charge. For the second set of model parameters, the pion condensation is impossible if the neutrality condition is imposed. The behaviour of meson masses vs quark chemical potential has been studied in electrically neutral matter.

description: This paper examines how the Brazilian food industry has been heavily affected by several recent institutional and economic changes. The food industry, including the processing and retail sectors, is part of a broader agribusiness system that conditions corporations' strategies, performance, and adoption of adequate governance structures. The Brazilian agroindustrialization process that preceded the formation of the sub-regional free-trade area (Mercosur) and economic liberalization influenced subsequent development of the agribusiness and food system in the Mercosur countries and their investment and trade links to countries outside Mercosur. The article emphasizes business strategies for coping with challenges and opportunities that have arisen from Mercosur integration, from economic stabilization programs and, more importantly, from a broad range of institutional changes such as trade liberalization, deregulation, and the friendlier treatment of foreign capital. These changes have together fostered the globalization process in the region and have stimulated different responses from large and small firms, all threatened by the new, competitive environment.

They are stored in spatially separated dense media deposed in an optical cavity. Specific sequences of pulses address individually the storage media to encode the qubits and to implement a universal set of gates. The proposed protocol is decoherence-free in the sense that spontaneous emission and cavity damping are avoided. We discuss a coupling scheme for experimental implementation in Neon atoms.

description: The role of G&S has shifted from a technical instrument to reduce transaction costs in homogeneous commodity markets to a strategic instrument of competition in differentiated product markets. The nature of G&S has shifted from performance (realized characteristics of the product) to process standards. In developing countries, these changes have tended to exclude small firms and farms from participating in market growth, because of the implied investments. The three strategic responses to G&S change by agribusiness firms and farms include: (1) by large firms and multinationals, to create private G&S and private certification, labeling, and branding systems; (2) by medium-large domestic firms, to lobby governments to adopt public G&S similar to those in export markets in developed regions; (3) by small firms and farms, to ally with public and nonprofit sectors to form G&S and certification systems to access export markets and to bring institutional change to nontradable product markets. Governments should build the capacity of the poor to invest to 'make the grade' implied by the new G&S.

description: Land resource depletion causes a range of consequences, such as threats to food security, increasing poverty, and social unrest. Therefore, reasonable and effective land use has become a crucial issue of the nation and localities nationwide. Research results in Tan Binh commune, Dak Doa district, Gia Lai Province in Vietnam showed that long-term industrial and agricultural land occupies most of the commune's agroforestry land. The study also had shown that there are six common land use types (LUTs) in the commune. In particular, the LUT of pepper cultivation had the highest economic benefit, whereas the LUT of coffee brought the highest social benefit. However, the LUT of chayote was the highest in overall benefits with Ect of 0.93; thus, this LUT should be widely applied throughout Tan Binh commune. The research results were a crucial scientific basis for proposing a group of suitable plants to local natural conditions to bring effective and sustainable efficiency in land-use types.

description: Motivated by experience in programming and in the teaching of programming, we make another assault on the longstanding problem of debugging. Having explored why debuggers are not used as widely as one might expect, especially in functional programming environments, we define the characteristics of a debugger which make it usable and thus likely to be widely used. We present work on a new debugger for the functional programming language OCaml which operates by direct interpretation of the program source, allowing the printing out of individual steps of the program’s evaluation, and discuss its technical implementation and practical use. It has two parts: a stand-alone debugger which can run OCaml programs by interpretation and so allow their behaviour to be inspected; and an OCaml syntax extension, which allows the part of a program under scrutiny to be interpreted in the same fashion as the stand-alone debugger whilst the rest of the program runs natively. We show how this latter mechanism can create a source-level debugging system that has the characteristics of a usable debugger and so may eventually be expected to be suitable for widespread adoption.

description: Small-scale industries in Indonesia provide more than 65% of total manufacturing employment. Sixty-three percent of small-scale firm employment is in firms that are clustered. A cluster is defined statistically in Indonesia as at least 20 firms in a village. For some agro-processing industries, such as bamboo plaiting, clustering does not involve interaction among firms; for others, notably the furniture industry, clustering firms make joint marketing efforts, subcontract each other, and share large orders. This article uses two recent case studies in the agro-processing sector - the furniture and the palm sugar industries - in Central Java. We argue that the target market of the industry (local or international) influences the nature of the contracts and other forms of interaction in the clusters. Targeting an international market requires formal contracts, more focus on marketing, and separate roles for finishing firms and subcontracting firms. Policy should be directed at enabling clusters to shift to the international market by improving contract enforcement regulations, vocational training, and providing opportunities for group lending.

description: When complex mechanisms are involved, pinpointing high-performance materials within large databases is a major challenge in materials discovery. We focus here on phonon-limited conductivities, and study 2D semiconductors doped by field effects. Using state-of-the-art density-functional perturbation theory and Boltzmann transport equation, we discuss 11 monolayers with outstanding transport properties. These materials are selected from a computational database of exfoliable materials providing monolayers that are dynamically stable and that do not have more than 6 atoms per unit cell. We first analyse electron-phonon scattering in two well-known systems: electron-doped InSe and hole-doped phosphorene. Both are single-valley systems with weak electron-phonon interactions, but they represent two distinct pathways to fast transport: a steep and deep isotropic valley for the former and strongly anisotropic electron-phonon physics for the latter. We identify similar features in the database and compute the conductivities of the relevant monolayers. This process yields several high-conductivity materials, some of them only very recently emerging in the literature (GaSe, Bi$_2$SeTe$_2$, Bi$_2$Se$_3$, Sb$_2$SeTe$_2$), others never discussed in this context (AlLiTe$_2$, BiClTe, ClGaTe, AuI). Comparing these 11 monolayers in detail, we discuss how the strength and angular dependency of the electron-phonon scattering drives key differences in the transport performance of materials despite similar valley structure. We also discuss the high conductivity of hole-doped WSe$_2$, and how this case study shows the limitations of a selection process that would be based on band properties alone.

description: In a 1983 paper, Yannelis-Prabhakar rely on Michael's selection theorem to guarantee a continuous selection in the context of the existence of maximal elements and equilibria in abstract economies. In this tribute to Nicholas Yannelis, we root this paper in Chapter II of Yannelis' 1983 Rochester Ph.D. dissertation, and identify its pioneering application of the paracompactness condition to current and ongoing work of Yannelis and his co-authors, and to mathematical economics more generally. We move beyond the literature to provide a necessary and sufficient condition for upper semi-continuous local and global selections of correspondences, and to provide application to five domains of Yannelis' interests: Berge's maximum theorem, the Gale-Nikaido-Debreu lemma, the Gale-McKenzie survival assumption, Shafer's non-transitive setting, and the Anderson-Khan-Rashid approximate existence theorem. The last resonates with Chapter VI of the Yannelis' dissertation.

description: Advances in agricultural biotechnology have led to interest by agribusiness to license elite germplasm from national programs in developing countries, now in need of funds. Uncertainties about the value of the material have delayed negotiations. This article proposes a method of setting upper (monopoly; no seed saving) and lower (competitive) negotiating bounds on values. The model accounts for (1) annual productivity enhancements, (2) effects on world prices, and (3) obsolescence effects of greater R&D. A demonstration application for soybeans in Brazil, which has completed the preconditions (IPR, biosafety, internal policy), suggests limited private value for public germplasm. The optimal solution is cooperation (licensing).

description: The Feynman-Kac formula provides a way to understand solutions to elliptic partial differential equations in terms of expectations of continuous time Markov processes. This connection allows for the creation of numerical schemes for solutions based on samples of these Markov processes which have advantages over traditional numerical methods in some cases. However, naïve numerical implementations suffer from statistical bias and sampling error. We present methods to discretize the stochastic process appearing in the Feynman-Kac formula that reduce the bias of the numerical scheme. We also propose using temporal difference learning to assemble information from random samples in a way that is more efficient than the traditional Monte Carlo method.

description: This article addresses the issue of whether different market institutions are accompanied by different degrees of efficiency and symmetry of price transmission between the producer and retail levels. It analyzes hog market institutions as they differ between the North and the South regions of Vietnam. The paper uses a price asymmetry model including an error correction term to reconcile potential cointegration relations with symmetry. The analysis shows that the market is efficient in conveying accurate information, provided public support institutions are in place.

description: The milk clusters in the Latin American countries studied share key characteristics in their patterns of development in the 1990s, in particular the rising importance of multinationals and large domestic firms in the processing and distribution segments of the milk products chains. This tends to reduce reliance on and transactions with smaller domestic firms in the milk industry, and induce intra-industry concentration and shifts toward use of more capital-intensive technology as well as shift of activity toward urban centers.

description: Background: Looked after children have high levels of unmet mental health needs across the world. This service gap is particularly pronounced in low- and middle-income countries such as Turkey. Research aims. The aims of this research were to explore the views and experiences of looked after children, carers, social workers and mental health professionals in relation to their mental health needs,supports within the care system, and interventions from mental health services. Methods: A qualitative design was employed. Semi-structured interviews were conducted with 15 children aged 14-18 years from four care homes in Istanbul, who had previously attended mental health services. In addition, interviews were undertaken with carers (n=9), social workers (n=7) employed in care settings, and psychiatrists (n=5). These were audio-taped, transcribed verbatim and analysed through a thematic framework. Results: difficulties, available supports within the are system, and experiences of mental health services. Children often felt abandoned and rejected within care settings, which led them to develop their own coping strategies such as through withdrawal, crying, isolation and loneliness. Fear of stigma, poor referral systems and lack of inter-agency working were perceived as key barriers to access and engage with mental health services. Interventions were largely based on pharmacological treatment, which was mostly viewed as ineffective. Engagement of children, psychotherapeutic interventions, inter-agency collaboration, and capacity-building for carers and staff were the main recommendations by stakeholders. Conclusions: These findings can enable policy-makers, service developers and professionals to better understand the nature of mental health needs experienced by looked after children and gaps in service provision; thus use this evidence-base to improve the quality of their mental health care in Turkey and other similar contexts around the world.
