description: We have theoretically studied the thermoelectric properties of serially coupled quantum dots (SCQD) embedded in an insulator matrix connected to metallic electrodes. In the framework of Keldysh Green's function technique, the Landauer formula of transmission factor is obtained by using the equation of motion method. Based on such analytical expressions of charge and heat currents, we calculate the electrical conductance, Seebeck coefficient, electron thermal conductance and figure of merit (ZT) of SCQD in the linear response regime. The effects of electron Coulomb interactions on the reduction and enhancement of ZT are analyzed. We demonstrate that ZT is not a monotonic increasing function of interdot electron hopping strength ($t_c$). We also show that in the absence of phonon thermal conductance, SCQD can reach the Carnot efficiency as $t_c$ approaches zero.

description: We study how the significance of top quark induced charge asymmetries at the LHC may be enhanced exploiting the $t\bar t$ total transverse momentum to enrich the fraction of quark fusion events in the sample. We combine this variable with previous variables related to the boost and the invariant mass of the $t\bar t$ pair to find an optimum cut which maximizes the significance of the asymmetry when systematic and statistic errors are taken into account. We find that including the $t\bar t$ transverse momentum in the analysis of the expected 2012 LHC data provides a considerable enhancement in the significance of the asymmetry.
description: Matches the Physical Review D accepted version. Includes the recent CMS results on the LHC ttbar induced asymmetry in which they use the ttbar transverse momentum for the first time. The results are adapted to their selection efficiency and resolution in ttbar transverse momentum of 20 GeV, which increases still more the enhancement in the significance. 18 pages, 11 figures

description: Electronic transport through chaotic quantum dots exhibits universal, system independent, properties, consistent with random matrix theory. The quantum transport can also be rooted, via the semiclassical approximation, in sums over the classical scattering trajectories. Correlations between such trajectories can be organized diagrammatically and have been shown to yield universal answers for some observables. Here, we develop the general combinatorial treatment of the semiclassical diagrams, through a connection to factorizations of permutations. We show agreement between the semiclassical and random matrix approaches to the moments of the transmission eigenvalues. The result is valid for all moments to all orders of the expansion in inverse channel number for all three main symmetry classes (with and without time reversal symmetry and spin-orbit interaction) and extends to nonlinear statistics. This finally explains the applicability of random matrix theory to chaotic quantum transport in terms of the underlying dynamics as well as providing semiclassical access to the probability density of the transmission eigenvalues.

description: We analyze the pattern forming ability and pattern stability for a one-dimensional non-linear transport-diffusion equation on the circle. We show that the trivial steady state is stable when diffusion is sufficiently strong. In the limit for vanishing diffusion, linear combinations of delta peaks can be stationary solutions; we study their stability properties. Finally, we present numerical examples exhibiting a variety of behaviors.

description: We draw upon historical evidence from several countries and contemporary studies of national innovation systems to argue that indigenous systems of academic training and public research have been in the past important elements of the institutional structures supporting a country's economic catch up. Recent changes in the international economic environment, and the growing scientific basis for contemporary technologies, will make those systems even more important in the future. The contributions of universities and public labs to the development of indigenous technological capabilities have taken different forms in different countries and economic sectors. However, we note that, in contrast with current emphasis on university-based embryonic inventions and fundamental research, effective research programs have predominantly occurred in the application-oriented sciences and engineering, and have been oriented towards problem-solving, and the advancement of technologies of interest to a well-defined user-community.

description: We demonstrate a new method for the calculation of inelastic scattering cross-section, which in contrary to the Regge-based methods takes into account the energy momentum conservation law. By virtue of this method it was shown that the main contribution to integral expressing inelastic scattering cross-sections comes not from the multi-Regge domain. In particular this leads to the fact that accounting of longitudinal momenta contribution to virtualities is sufficient and results in the new mechanism of cross-section growth. The necessity of taking into account the large number of interference contributions is shown and the approximate method for this purpose is developed. By considering the interference contributions from a single fitting constant achieved a qualitative agreement of the total and inelastic cross sections with experimental data.

description: We investigate the effect of helium on hydrogen reionisation using a hydrodynamical simulation combined with the cosmological radiative transfer code CRASH. The simulations are run in a 35.12/h comoving Mpc box using a variety of assumptions for the amplitude and power-law extreme-UV (EUV) spectral index, alpha, of the ionising emissivity. We use an empirically motivated prescription for ionising sources which ensures all of the models are consistent with constraints on the Thomson scattering optical depth and the hydrogen photo-ionisation rate at z=6. The inclusion of helium slightly delays reionisation due to the small number of ionising photons which reionise neutral helium instead of hydrogen. However, helium has a significant impact on the thermal state of the IGM. Models with alpha=3 produce IGM temperatures at the mean density at z=6 which are about 20 % higher compared to models without helium photo-heating. Harder EUV indices produce even larger IGM temperature boosts. A comparison to recent observational estimates of the IGM temperature at z=5 - 6 suggests that hydrogen reionisation was primarily driven by pop-II stellar sources with a soft EUV index, alpha<3. We also find that faint, as yet undetected galaxies, characterised by a luminosity function with a steepening faint-end slope and an increasing Lyman continuum escape fraction (fesc=0.5), are required to reproduce the ionising emissivity used in our simulations at z>6. Finally, we note there is some tension between recent observational constraints which indicate the IGM is > 10% neutral by volume z=7, and estimates of the ionising emissivity at z=6 which indicate only between 1 and 3 ionising photons are emitted per hydrogen atom over a Hubble time. This tension may be alleviated by either a lower neutral fraction at z=7 or an IGM which still remains a few % neutral by volume at z=6.

description: The basal thermal regime of ice sheets exerts a strong control on ice‐sheet stability and the onset of rapidly streaming flow. However, the nature of this thermal transition where sliding initiates is largely unconstrained by geophysical observations. In the Greenland Ice Sheet, topographic troughs or elevated geothermal heat fluxes typically define the onset of outlet glaciers. In contrast, Petermann Glacier in Northern Greenland does not have any distinct bed troughs or localized geothermal heating associated with its onset, making it an ideal site to investigate the basal thermal state and examine its role in the onset of Petermann Glacier. Here we use radar bed reflectivity and an ice‐sheet thermomechanical model to examine the basal thermal regime beneath Petermann Glacier. Our results reveal a complex thermal transition near the onset of Petermann Glacier. As the bed shifts from largely frozen to largely thawed with increasing distances from the ice divide, our results show that this thermal transition happens through alternating bands of frozen and thawed bands. The complex thermal state across the onset region suggests that lateral meltwater injection and local meltwater production determine the location of Petermann Glacier. Given the lack of topographic pinning at the onset location, the upstream margin of Petermann is vulnerable to migrate depending on a combination of advective cooling and meltwater supply from the interior of the ice sheet.

description: We introduce a methodology for determining the transport distance of subglacially comminuted and entrained sediments. We pilot this method on sediments from the terminal margin of the Baltic Ice Stream, the largest ice stream of the Fennoscandian Ice Sheet during the Last Glacial Maximum. A strong correlation (R2 = 0.83) between the εNd and latitudes of circum-Baltic river sediments enables us to use εNd as a calibrated measure of distance. The proportion of subglacially transported sediments in a sample is estimated from grain size ratios in the silt fraction (<63 μm). Coupled εNd and grain size analyses reveal a common erosion source for the Baltic Ice Stream sediments located near the Åland sill, more than 850 km upstream from the terminal moraines. This result is in agreement with both numerical modeling and geomorphological investigations of Fennoscandinavian erosion, and is consistent with rapid ice flow into the Baltic basins prior to the Last Glacial Maximum. The methodology introduced here could be used to infer the distances of glacigenic sediment transport from Late Pleistocene and earlier glaciations.

description: No abstracts are to be cited without prior reference to the author.The reasons for the alarming decline of the European eel, Anguilla anguilla L., population are unknown. Conservation action is nevertheless needed, and is also demanded by European legislation. To understand fisheries stakeholders’ preferences for various eel conservation tools and thereby inform eel conservation planning, an innovative survey method, the maximum difference conjoint, was applied to recreational anglers in northern Germany. Results were used to develop a decision support tool to predict stakeholders’ support for eel conservation policies. Recreational anglers preferred moderately more restrictive eel harvest regulations but strongly opposed any form of effort and gear limitation. They strongly favoured tighter constraints on other sources of eel mortality (e.g. commercial fishing, cormorants, hydropower) along with increased stocking efforts compared to increased regulation of recreational eel angling. Overall, however, anglers were supportive of management portfolios that included regulations of recreational fishing along with regulations of other eel mortality sources provided some success in terms of increased eel escapement was guaranteed. This result was unexpected given the pronounced aversion towards tighter eel angling regulations highlighting the suitability of our nested survey approach to understand stakeholder trade-offs for complex resource conservation problems. Our results suggest that implementation of successful eel conservation policies must consider joint regulation of all sectors that potentially affect eel stocks negatively. Otherwise, management conflicts are very likely. The application of the social survey technique presented in this paper is encouraged to other fisheries conservation contexts, where biological reasons for declining resources are uncertain and multiple stakeholder interests must be considered

description: Accurate quantification of surface snow accumulation over Antarctica is a key constraint for estimates of the Antarctic mass balance, as well as climatic interpretations of ice-core records. Over Antarctica, near-surface winds accelerate down relatively steep surface slopes, eroding and sublimating the snow. This wind scour results in numerous localized regions (<=200 km^2) with reduced surface accumulation. Estimates of Antarctic surface mass balance rely on sparse point measurements or coarse atmospheric models that do not capture these local processes, and overestimate the net mass input in wind-scour zones. Here we combine airborne radar observations of unconformable stratigraphic layers with lidar-derived surface roughness measurements to identify extensive wind-scour zones over Dome A, in the interior of East Antarctica. The scour zones are persistent because they are controlled by bedrock topography. On the basis of our Dome A observations,we develop an empirical model to predict wind-scour zones across the Antarctic continent and find that these zones are predominantly located in East Antarctica. We estimate that ~2.7–6.6% of the surface area of Antarctica has persistent negative net accumulation due to wind scour, which suggests that, across the continent, the snow mass input is overestimated by 11–36:5 Gt yr-1 in present surface-massbalance calculations.

description: Traditional monitoring and evaluation tools are often costly and are not well placed to assess complex, multi-dimensional dynamic livelihood attributes, such as resilience. While these approaches may be accurate in measurement, they often fail to empower respondents to take action. Drawbacks of other participatory resilience approaches include a requirement for a large amount of information, significant time required to administer surveys, and data analysis burdens (Schipper and Langston 2015, 19; COP 2016). They also need a baseline and an end line to assess change. They typically fail to capture how farmers actively address specific shocks and stresses or what lessons can be learned. Given these limitations, an opportunity exists to review alternative approaches and develop different tools. Our approach and tool, farmbetter, attempts to build on lessons learned from developing and implementing these tools. Rather than characterizing the user as lacking agency in a challenging environment, farmbetter helps users make conscious decisions to adapt and withstand specific shocks and stresses such as floods, drought, or conflict, which can require contradictory coping strategies. We aim to then further connect farmers whose properties have similar agro-ecological conditions and challenges to better facilitate knowledge-sharing between food producers, ultimately improving learning and resilience. This allows for the connection of big data with (traditional) knowledge and competences already being used by farmers to improve resilience. This is enabled by advances in technology (e.g. mobile phone availability), which offer new opportunities to more easily and cheaply collect data as well as giving access to marginalized groups’ views and knowledge (e.g. Raghavan et al. 2016).

description: The structural, electronic and magnetic properties of the Kondo-lattice system CeRuSi2 are experimentally investigated and analyzed in the series of other ternary cerium compounds. This system is shown to be an excellent model system demonstrating coexistence of the Kondo effect and anomalous ferromagnetism with a small magnetic moment which is confirmed by magnetic and μSR measurements. Data on specific heat, resistivity and Seebeck coefficient are presented. Being deduced from the resistivity and specific heat data, the non-Fermi-liquid behavior is observed at low temperatures, which is unusual for a ferromagnetic Kondo system. A comparison with other magnetic Kondo lattices is performed.

description: In September 2016, the annual meeting of the International Union for Quaternary Research’s Loess and Pedostratigraphy Focus Group, traditionally referred to as a LoessFest, met in Eau Claire, Wisconsin, USA. The 2016 LoessFest focused on “thin” loess deposits and loess transportation surfaces. This LoessFest included 75 registered participants from 10 countries. Almost half of the participants were from outside the United States, and 18 of the participants were students. This review is the introduction to the special issue for Quaternary Research that originated from presentations and discussions at the 2016 LoessFest. This introduction highlights current understanding and ongoing work on loess in various regions of the world and provides brief summaries of some of the current approaches/strategies used to study loess deposits.

The k-th iterate of λ(n) is denoted by λk(n) In this work we will show the normal order for log(n/λk(n)) is (loglog n)k⁻¹}(logloglog n)/(k-1)! . Second, we establish a similar normal order for other iterate involving a combination of λ(n) and Φ(n). Lastly, define L(n) to be the smallest k such that λ_k(n)=1. We determine new upper and lower bounds for L(n) and conjecture a normal order.

description: No abstracts are to be cited without prior reference to the author.Management and monitoring of fisheries requires the availability of time series of economic indicators. Traditionally, wages and profits are monitored as they are considered key components for the understanding of fishermen behaviour and fleet dynamics. Furthermore, an ecosystem approach to fisheries can then be applied by integrating economic and ecological indicators and trying to highlight the interactions between these two components. Such an integrated analysis of the joint dynamics of the fish community and fleets has been undertaken for the Bay of Biscay where exploitation is characterized by a large diversity of species and fleets. Economic indicators were calculated for the time period of 2000-2007 using data collected by Ifremer under the Data Collection Regulation. Given the specific context of increasing fuel prices, results showed negative relationships between profits and wages and high differences in profitability between fleets, opposing coastal and larger vessels. These first results raise issues on the relevance of these traditional economic indicators and the definition of reference points to provide a diagnostic of the economic status of fisheries. This study also highlights the difficulties to estimate economic indicators given the weakness of the data sources and the specific structure of the fleet where most of the vessels are less than 10 meters. Finally, the use of data made available under the DCR for such integrated analysis is discussed.

description: The Eastern Himalayas in India demonstrate vast ecological diversity in its varied range of flora and fauna. The local communities also form an integral part of the ecological landscape, deriving various services from the forest and mountain ecosystems. Recently, however, due to severe anthropogenic pressure and unplanned developmental activities, the Eastern Himalayans have displayed signs of rapid habitat destruction. This photo essay aims to discuss the nature of the challenges in the Eastern Himalayas which pose a palpable threat to the local ecology and environment, and to establish how a more sustainable approach is necessary to salvage this ecologically unique region.

description: Experiments measuring friction over a wide range of sliding velocities find that the value of the friction coefficient varies widely: friction is high and behaves according to the rate and state constitutive law during slow sliding, yet markedly weakens as the sliding velocity approaches seismic slip speeds. We introduce a physics‐based theory to explain this behavior. Using conventional microphysics of creep, we calculate the velocity and temperature dependence of contact stresses during sliding, including the thermal effects of shear heating. Contacts are assumed to reach a coupled thermal and mechanical steady state, and friction is calculated for steady sliding. Results from theory provide good quantitative agreement with reported experimental results for quartz and granite friction over 11 orders of magnitude in velocity. The new model elucidates the physics of friction and predicts the connection between friction laws to independently determined material parameters. It predicts four frictional regimes as function of slip rate: at slow velocity friction is either velocity strengthening or weakening, depending on material parameters, and follows the rate and state friction law. Differences between surface and volume activation energies are the main control on velocity dependence. At intermediate velocity, for some material parameters, a distinct velocity strengthening regime emerges. At fast sliding, shear heating produces thermal softening of friction. At the fastest sliding, melting causes further weakening. This theory, with its four frictional regimes, fits well previously published experimental results under low temperature and normal stress.

description: Several surgical techniques are available for an adult patient collective with diastasis recti. Only few research papers addresses the treatment options of diastasis of the rectus abdominis in children. In this case series, we present a new technique of epifascial repair as a novel possibility in successfully repairing defects of the anterior abdominal wall using minimally invasive surgery. In this case series, we present an epifascial repair technique for patients with a diastasis recti with a dehiscence cranial of the umbilicus. Four pediatric patients with symptomatic rectus diastasis were treated with this new surgical technique. All procedures were conducted successfully, and no recurrence was observed in the follow up. All patients showed clinical regression of the rectus diastasis without any postoperative abdominal wall protrusion and good improvement of the symptoms. Intraoperative intraperitoneal air loss, postoperative scar keloid, thermal lesions due to Ultracision and one seroma/hematoma after the removal of the drain were minor complications observed during the follow-up.

Of these focus areas, we are commencing specific projects to explore the first two items. In this paper, we share our proposed solution to global health issues from the perspective of the effective promotion of Public Private Partnerships (PPPs). Mitsubishi UFJ Research and Consulting (MURC) is a comprehensive think tank/consulting arm of the Mitsubishi UFJ Financial Group (the MUFG Group, a universal banking group that represents Japan) and based in the three major cities in Japan. MURC established the “Center on Global Health Architecture” in 2017 and organized a public private collaborative action-oriented research meeting on global health issues. We aim to promote relationships among stakeholders, “break down silos,” and take an interdisciplinary approach to create new and innovative projects.

description: Six recurrent thermal regimes are identified over continental North America from June to September through a k-means clustering applied to daily maximum temperature simulated by ECHAM5 forced by his- torical SSTs for 1930–2013 and validated using NCEP–DOE AMIP-II reanalysis over the 1980–2009 period. Four regimes are related to a synoptic wave pattern propagating eastward in the midlatitudes with embedded ridging anomalies that translate into maximum warming transiting along. Two other regimes, associated with broad continental warming and above average temperatures in the northeastern United States, respectively, are characterized by ridging anomalies over North America, Europe, and Asia that suggest correlated heat wave occurrences in these regions. Their frequencies are mainly related to both La Niña and warm conditions in the North Atlantic. Removing all variability beyond the seasonal cycle in the North Atlantic in ECHAM5 leads to a significant drop in the occurrences of the regime associated with warming in the northeastern United States. Superimposing positive (negative) anomalies mimicking the Atlantic multidecadal variability (AMV) in the North Atlantic translates into more (less) warming over the United States across all regimes, and does alter regime frequencies but less significantly. Regime frequency changes are thus primarily controlled by Atlantic SST variability on all time scales beyond the seasonal cycle, rather than mean SST changes, whereas the in- tensity of temperature anomalies is impacted by AMV SST forcing, because of upper-tropospheric warming and enhanced stability suppressing rising motion during the positive phase of the AMV.

description: The purpose of this paper and its prequel (Toric Stacks I) is to introduce and develop a theory of toric stacks which encompasses and extends the notions of toric stacks defined in [Laf02, BCS05, FMN10, Iwa09, Sat12, Tyo12], as well as classical toric varieties. While the focus of the prequel is on how to work with toric stacks, the focus of this paper is how to show a stack is toric. For toric varieties, a classical result says that any normal variety with an action of a dense open torus arises from a fan. In [FMN09, Theorem 7.24], it is shown that a smooth separated DM stack with an action of a dense open stacky torus arises from a stacky fan. In the same spirit, the main result of this paper is that any Artin stack with an action of a dense open torus arises from a stacky fan under reasonable hypotheses.

Semiparametric Regression for Dual Population Mortality
Creators: name: Venter, Gary

Publisher: name: Columbia University
Year: 2019
Subjects: Actuarial science
Bayesian statistical decision theory
Parameter estimation
Mortality--Mathematical models

description: Parameter shrinkage applied optimally can always reduce error and projection variances from those of maximum likelihood estimation. Many variables that actuaries use are on numerical scales, like age or year, which require parameters at each point. Rather than shrinking these towards zero, nearby parameters are better shrunk towards each other. Semiparametric regression is a statistical discipline for building curves across parameter classes using shrinkage methodology. It is similar to but more parsimonious than cubic splines. We introduce it in the context of Bayesian shrinkage and apply it to joint mortality modeling for related populations, with Swedish and Danish mortality as an illustration. Bayesian shrinkage of slope changes of linear splines is an approach to semiparametric modeling that evolved in the actuarial literature. It has some theoretical and practical advantages, like closed-form curves, direct and transparent determination of degree of shrinkage and of placing knots for the splines, and quantifying goodness of fit. It is also relatively easy to apply to the many nonlinear models that arise in actuarial work.
title: Incorporating stakeholders' knowledge to stock assessment: how?

description: No abstracts are to be cited without prior reference to the author.In this paper we present a method by which the knowledge of stakeholders can be taken into account in stock assessment. The approach consists of a structured interview process followed by quantitative modelling of the answers. The outcome is a set of probability models, each describing the views of different stakeholder. Graphical representations of the models can be used to explore and communicate the differences and similarities between the views of stakeholders. Individual models are then merged to a large model by using the techniques of Bayesian model averaging, and this model is conditioned on stock assessment data. As result, the model can be used to give management advice where the views of interviewed stakeholders have been taken into account with a weight determined based on how well the views are supported by the observed data. The individual stakeholder models can also be analysed separately to see whether the different views imply different advice or not.

description: The present study focuses on alcohol use disorder, the most prevalent substance use disorder, which causes approximately 3 million deaths yearly. Based on literature search and analysis of the protein candidates in the Bioprofiling.de and PANTHER classification system we identified almost a hundred pathways with potential significance. These targets will be subsequently validated through cell and animal studies and provide potential biomarkers to the next stages of clinical trials.
Magnetic field dependence of spin-lattice relaxation in the s$\pm$ state of Ba$_{0.67}$K$_{0.33}$Fe$_{2}$As$_{2}$

description: The spatially averaged density of states, , of an unconventional d-wave superconductor is magnetic field dependent, proportional to $H^{1/2}$, owing to the Doppler shift of quasiparticle excitations in a background of vortex supercurrents[1,2]. This phenomenon, called the Volovik effect, has been predicted to exist for a sign changing $s\pm$ state [3], although it is absent in a single band s-wave superconductor. Consequently, we expect there to be Doppler contributions to the NMR spin-lattice relaxation rate, $1/T_1 \propto $, for an $s\pm$ state which will depend on magnetic field. We have measured the $^{75}$As $1/T_1$ in a high-quality, single crystal of Ba$_{0.67}$K$_{0.33}$Fe$_{2}$As$_{2}$ over a wide range of field up to 28 T. Our spatially resolved measurements show that indeed there are Doppler contributions to $1/T_1$ which increase closer to the vortex core, with a spatial average proportional to $H^2$, inconsistent with recent theory [4]

On a scale-invariant Fermi gas in a time-dependent harmonic potential

description: We investigate a scale-invariant two-component Fermi gas in a time-dependent isotropic harmonic potential. The exact time evolution of the density distribution in position space in any spatial dimension is obtained. Two experimentally relevant examples, an abrupt change and a periodic modulation of the trapping frequency are solved. Small deviations from scale invariance and isotropy of the confinement are addressed within first order perturbation theory. We discuss the consequences for experiments with ultracold quantum gases such as the excitation of a tower of undamped breathing modes and a new alternative for measuring the Tan contact.
