description: We have investigated second harmonic generation (SHG) from Ag-coated LiNbO3 (LN) core-shell nanocuboids and found that giant SHG can occur via deliberately designed double plasmonic resonances. By controlling the aspect ratio, we can tune fundamental wave (FW) and SHG signal to match the longitudinal and transverse plasmonic modes simultaneously, and achieve giant enhancement of SHG by more than five orders of magnitude in comparison to a bare LN nanocuboid and by about one order of magnitude to the case adopting only single plasmonic resonance. The underlying key physics is that the double-resonance nanoparticle enables greatly enhanced trapping and harvesting of incident FW energy, efficient internal transfer of optical energy from FW to SHW, and much improved power to transport the SHG energy from the nanoparticle to the far-field region. The proposed double-resonance nanostructure can serve as an efficient subwavelength coherent light source through SHG and enable flexible engineering of light-matter interaction at nanoscale.

description: We develop a network-flow approach for characterizing interim-allocation rules that can be implemented by ex post allocations. Our method can be used to characterize feasible interim allocations in general multi-unit auctions where agents face capacity constraints, both ceilings and floors. Applications include a variety of settings of practical interest, ranging from individual and group-specific capacity constraints, set-aside sale, partnership dissolution, and government license reallocation.

description: Additional file 3. Determination of binding affinity of K11 to isoD7-Aβ (1–18). The interaction of Aβ peptides with K11 was analyzed at a Biacore 3000 at 25 °C. Goat anti mouse IgG was immobilized on a CM5 sensor chip, followed by binding of mouse anti-isoD7-Aβ antibody K11. The binding affinity of isoD7-Aβ (1–18) was analyzed by five consecutive injections of 3 nM, 9 nM, 27 nM, 81 nM and 243 nM of the peptide. The obtained sensorgram was evaluated using the single-cycle-kinetic model getting following constants: ka = 4.07·104 M− 1 s− 1; kd = 2.57·10− 4 s− 1 and KD = 6.31 nM.

description: We examine the effects of speculation using credit derivatives on the cost of debt and the likelihood of default. The availability of credit default swaps induces investors who are optimistic about borrower revenues to sell protection instead of buying bonds. This benefits borrowers if protection can only be bought with an insurable interest, but can increase the cost of debt and crowd out productive lending if protection can be purchased as a bet on default. We also show that the possibility of speculation on default may cause multiple equilibria and exacerbate the problem of rollover risk.

Insurance Enterprise Risk Management: Toward The Next Generation

Publisher: name: Columbia University
Year: 2013
Subjects: Economics

description: The practice of enterprise risk management (ERM) in the insurance industry has improved in recent years. This is partly because insurers have strived to reinforce risk-based management, and partly due to regulatory pressure triggered by the financial crisis as well as increasingly large natural catastrophes. Insurers’ activities have expanded across many countries and markets. They must work within an increasingly difficult and complicated environment due to rapid globalization, technological development, and changes in nature (particularly in terms of climate change and earth movement). In order to overcome such increasing uncertainty around the Internationally Active Insurance Groups (IAIGs), they should improve their ERM, and regulators and insurers should cooperate with each other in order to create a market-based solution for these extreme events. This paper aims to review the current actions of regulators and insurers, and then summarize how we improve insurance ERM toward the next generation. The main components to consider are complementary mechanisms for the bounds of internal model and rational decision-making, and the reinforcement of a market-based solution mechanism.

description: Integrating robots in complex everyday environments requires a multitude of problems to be solved. One crucial feature among those is to equip robots with a mechanism for teaching them a new task in an easy and natural way. When teaching tasks that involve sequences of different skills, with varying order and number of these skills, it is desirable to only demonstrate full task executions instead of all individual skills. For this purpose, we propose a novel approach that simultaneously learns to segment trajectories into reoccurring patterns and the skills to reconstruct these patterns from unlabelled demonstrations without further supervision. Moreover, the approach learns a skill conditioning that can be used to understand possible sequences of skills, a practical mechanism to be used in, for example, human-robot-interactions for a more intelligent and adaptive robot behaviour. The Bayesian and variational inference based approach is evaluated on synthetic and real human demonstrations with varying complexities and dimensionality, showing the successful learning of segmentations and skill libraries from unlabelled data.

description: Our goal is to establish what seems to be the first rigidity result for CR embeddings between Shilov boundaries of bounded symmetric domains of higher rank. The result states that any such CR embedding is the standard linear embedding up to CR automorphisms. Our basic assumption extends precisely the well-known optimal bound for the rank one case. There are no other restrictions on the ranks, in particular, the difficult case when the target rank is larger than the source rank is also allowed.

description: Recent experimental advances enabled the realization of mobile impurities immersed in a Bose-Einstein condensate (BEC) of ultracold atoms. Here we consider impurities with two or more internal hyperfine states, and study their radio-frequency (RF) absorption spectra, which correspond to transitions between two different hyperfine states. We calculate RF spectra for the case when one of the hyperfine states involved interacts with the BEC, while the other state is non-interacting, by performing a non-perturbative resummation of the probabilities of exciting different numbers of phonon modes. In the presence of interactions the impurity gets dressed by Bogoliubov excitations of the BEC, and forms a polaron. The RF signal contains a delta-function peak centered at the energy of the polaron measured relative to the bare impurity transition frequency with a weight equal to the amount of bare impurity character in the polaron state. The RF spectrum also has a broad incoherent part arising from the background excitations of the BEC, with a characteristic power-law tail that appears as a consequence of the universal physics of contact interactions. We discuss both the direct RF measurement, in which the impurity is initially in an interacting state, and the inverse RF measurement, in which the impurity is initially in a non-interacting state. In the latter case, in order to calculate the RF spectrum, we solve the problem of polaron formation: a mobile impurity dynamically gets dressed by Bogoliubov phonons. Our solution based on a time-dependent variational ansatz of coherent states of Bogoliubov phonons, becomes exact when the impurity is localized. Moreover we show that such an ansatz compares well with a semiclassical estimate of the propagation amplitude of a mobile impurity in the BEC. Our technique can be extended to cases when both initial and final impurity states interact with the BEC.

description: These lecture notes review the theoretical background to the Higgs boson, provide an introduction to its phenomenology, and describe the experimental tests that lead us to think that “beyond any  reasonable doubt, it is a Higgs boson". Motivations for expecting new physics beyond the Standard Model are recalled, and the Standard Model effective field theory is advocated as a tool to help search for it. The phenomenology of N = 1 and N = 2 supersymmetric Higgs bosons is reviewed, and the prospects for possible future Higgs factories are previewed.

description: We investigated the optical lightcurve of T Pyx during its 2011 outburst by compiling a database of SMEI and AAVSO observations. The SMEI lightcurve, providing unprecedented detail covering 1.5-49d post-discovery, was divided into four phases based on the idealised CN optical lightcurve; the initial rise (1.5-3.3d), the pre-maximum halt (3.3-13.3d), the final rise (14.7-27.9d), and the early decline (27.9d-). The SMEI lightcurve contains a strongly detected period of 1.44+/-0.05d during the pre-maximum phase. These oscillations resemble those found in TNR models arising from instabilities in the expanding envelope. No spectral variation mirroring the lightcurve periodicity was found. A marked dip at 22-24d just before maximum light (27.9d) may represent the same phenomenon seen in novae observed by SMEI. Spectra from the Liverpool Telescope and SMARTS 1.5m were obtained from 0.8-80.7 and 155.1-249.9d, covering the major phases of development. A distinct high velocity ejection phase was evident during the early rise (V~4000 km/s). A marked drop at 5.7d, and then a gradual increase occurred in the ejection velocity which stabilised at ~1500 km/s at the pre-maximum halt. Here we propose two stages of mass loss, a short-lived phase occurring immediately after outburst, lasting ~6d, followed by a steadily evolving and higher mass loss phase. The overall spectral development follows that typical of a CN and comparison with the photometric behaviour reveals consistencies with the evolving pseudo-photosphere model of a CN outburst. Comparing optical spectra to X-ray and radio lightcurves, weak [Fe X] 6375 Angstrom emission was marginally detected before the X-ray rise and was clearly present during the brightest phase of X-ray emission. If the onset of the X-ray phase and the start of the optical final decline are related to the cessation of significant mass loss, then this occurred at 90-110d.

description: Quantum Chromo Dynamics (QCD) provides the theoretical framework for any study of TeV scale physics at LHC. Being familiar with the basic concepts and techniques of QCD is therefore a must for any high-energy physicist. In these notes we consider Higgs production via gluon fusion as an example on how accurate and ﬂexible predictions can be obtained in perturbative QCD. We start by illustrating how to calculate the total cross section at the leading order (yet one loop) in the strong coupling α S and go through the details of the nextto-leading order calculation eventually highlighting the limitations of ﬁxedorder predictions at the parton level. Finally, we brieﬂy discuss how more exclusive (and practical) predictions can be obtained through matching/merging ﬁxed-order results with parton showers.

description: In this lecture, we briefly review the nonrelativistic QCD (NRQCD) factorization approach to describe the quarkonium production and decay. In the NRQCD factorization formula, the long-distance nature of a heavy quarkonium is factorized into the NRQCD long-distance matrix elements (LDMEs) and a physical measurable is expressed as a linear combination of the LDMEs. If we apply the perturbation theory to enhance the theoretical accuracies in the short-distance contributions there is no way to avoid non-analytic Coulomb divergences in the static limit of the heavy quark and infrared divergences. A systematic procedure to isolate such long-distance contributions out of the correction terms in the short-distance coefficients is called matching. As a heuristic example of finding the NRQCD factorization formula for a specific process, we demonstrate the matching procedure of determining the short-distance coefficients involving the leptonic decay of the $S$-wave spin-triplet state.

description: Purpose: To demonstrate anatomic and physiologic changes in the human choroid following systemic sildenafil citrate (Viagra) using enhanced depth imaging spectral domain–optical coherence tomography (EDI-OCT) and swept-scan high-frequency digital ultrasound. Methods: Seven healthy male subjects (mean age 32.7 years) were evaluated at baseline and 2 hr after ingesting 50 mg of sildenafil. Swept-scan high-frequency digital ultrasound and EDI-OCT were utilized to measure choroidal perfusion and thickness, respectively. Results were read by masked observers. The Wilcoxon signed-rank test and t-test were used to analyse differences in choroidal flow and thickness at baseline and 2 hr after ingestion of sildenafil. Results: Two hours following sildenafil, increased choroidal perfusion was observed in 11 of 12 eyes measured by swept-scan high-frequency digital ultrasound. The mean increase was 3.46 (±2.00) times baseline with a range of 0.47–7.80 times baseline (p = 0.004). Increased choroidal thickness was observed in 12 of 12 eyes measured with EDI-OCT. The average choroidal thickness increased by 11.6% temporal to the fovea, 9.3% nasal to the fovea and 10.7% underneath the fovea (p < 0.001 for all values). Conclusions: Choroidal perfusion and thickness both increase in response to systemic sildenafil. These changes could secondarily affect retinal function, explain previously reported clinical symptoms and potentially be a useful adjunct for treatment of ocular diseases that would benefit from increased choroidal blood flow.

description: Splitting of the nuclei of comets into multiple components has been frequently observed but, to date, no main-belt asteroid has been observed to break-up. Using the Hubble Space Telescope, we find that main-belt asteroid P/2013 R3 consists of 10 or more distinct components, the largest up to 200 m in radius (assumed geometric albedo of 0.05) each of which produces a coma and comet-like dust tail. A diffuse debris cloud with total mass roughly 2x10^8 kg further envelopes the entire system. The velocity dispersion among the components is about V = 0.2 to 0.5 m/s, is comparable to the gravitational escape speeds of the largest members, while their extrapolated plane-of-sky motions suggest break-up between February and September 2013. The broadband optical colors are those of a C-type asteroid. We find no spectral evidence for gaseous emission, placing model-dependent upper limits to the water production rate near 1 kg/s. Breakup may be due to a rotationally induced structural failure of the precursor body.

description: In this work, the influence of hydrogen bonds on structure and thermodynamic properties of binary mixtures of protic ionic liquids (PILs), sharing the same cation, are investigated with molecular dynamics simulation. The observed non-ideal mixing behavior can be explained with the formation of complex hydrogen-bonded clusters. With the help of a newly developed simple lattice model the clusters can be described. Furthermore, the model shows that the mixing process is enthalpy-driven, not entropy-driven as one would expect.

description: This paper surveys the landscape of linked open data projects in cultural heritage, examining the work of groups from around the world. Traditionally, linked open data has been ranked using the five star method proposed by Tim Berners-Lee. We found this ranking to be lacking when evaluating how cultural heritage groups not merely develop linked open datasets, but find ways to use linked data to augment user experience. Building on the five-star method, we developed a six-stage life cycle describing both dataset development and dataset usage. We use this framework to describe and evaluate fifteen linked open data projects in the realm of cultural heritage.

title: Intrinsic motivation and mental replay enable efficient online adaptation in stochastic recurrent networks

description: Autonomous robots need to interact with unknown, unstructured and changing environments, constantly facing novel challenges. Therefore, continuous online adaptation for lifelong-learning and the need of sample-efficient mechanisms to adapt to changes in the environment, the constraints, the tasks, or the robot itself are crucial. In this work, we propose a novel framework for probabilistic online motion planning with online adaptation based on a bio-inspired stochastic recurrent neural network. By using learning signals which mimic the intrinsic motivation signal cognitive dissonance in addition with a mental replay strategy to intensify experiences, the stochastic recurrent network can learn from few physical interactions and adapts to novel environments in seconds. We evaluate our online planning and adaptation framework on an anthropomorphic KUKA LWR arm. The rapid online adaptation is shown by learning unknown workspace constraints sample-efficiently from few physical interactions while following given way points.

description: Timeline of technology advances at the NYC Office of Emergency Management. Period One - Pre-9/11: Characterized by the establishment of the Mayor’s Office of Emergency Management, the beginnings of a central GIS unit, release of a common NYC Basemap and the first mobile command vehicle. Control of data and systems still largely held by individual agencies. Period Two - 2001-2005: Characterized by development of information systems to support interagency cooperation and response management. As of 2001, OEM is established as a City Department. New systems introduced include CALMS: Citywide Asset and Logistics Management System; UVIS: Unified Victim Identification System (call center, missing persons and family assistance modules) and CIMS: Citywide Incident Management System. Mobile Data Center, a custom-built bus for GIS and data collection operations introduced. Beginning of improved public initiatives, including publication of Ready NY Guides, pilot of CERT program (Community Emergency Response Team volunteer training), and the introduction of the 311 call center. Period Three – 2006-2008: Characterized by continued integration and interoperability of information systems across agencies. OEM Headquarters Opens at 165 Cadman Plaza, providing a state of the art Watch Command center and Emergency Operations Center. A Continuity of Operations planning guide standardized the planning process for City agencies to restore and maintain essential public services in the event of an emergency. An Interagency Command Vehicle was introduced, providing an onsite mobile operations unit that is smaller and more maneuverable than the larger command vehicles. The NYCityMap website launched publicly, along with additional editions of the Ready NY guides and specialized tools like the Hurricane Evacuation Zone Finder replaced EMOLS, which had previously only been activated in an emergency. Period Four – 2009-2011: Characterized by improved training and simulation software, and open public initiatives. The CIMS Mobile Coordination Center (MCC) was introduced, to serve as a mobile field office for City agencies and other emergency officials/personnel responding to a large disaster. When fully expanded, the MCC can accommodate a meeting of 40 people, or provide 20 work stations equipped with phones, computers, and internet service. NYCWiN-NYC Wireless Network and IVS - Interoperable Video Management System were introduced, allowing access to data and incident-based video feeds by mobile response units. Notify NYC and 311 Online, social media channels allowing the public to receive notices, submit inquiries and report incidents, were introduced.

Operational Rate-Distortion Performance of Single-source and Distributed Compressed Sensing

Publisher: name: arXiv
Year: 2014
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: We consider correlated and distributed sources without cooperation at the encoder. For these sources, we derive the best achievable performance in the rate-distortion sense of any distributed compressed sensing scheme, under the constraint of high--rate quantization. Moreover, under this model we derive a closed--form expression of the rate gain achieved by taking into account the correlation of the sources at the receiver and a closed--form expression of the average performance of the oracle receiver for independent and joint reconstruction. Finally, we show experimentally that the exploitation of the correlation between the sources performs close to optimal and that the only penalty is due to the missing knowledge of the sparsity support as in (non distributed) compressed sensing. Even if the derivation is performed in the large system regime, where signal and system parameters tend to infinity, numerical results show that the equations match simulations for parameter values of practical interest.

description: We present a recalibration of the luminosity-metallicity relation for gas-rich, star-forming dwarfs to magnitudes as faint as M$_R$ ~ -13. We use the Dopita et al. (2013) metallicity calibrations to calibrate the relation for all of the data in this analysis. In metallicity-luminosity space we find two sub-populations within a sample of high-confidence SDSS DR8 star-forming galaxies; 52% are metal-rich giants and 48% are metal-medium galaxies. Metal-rich dwarfs classified as tidal dwarf galaxy (TDG) candidates in the literature are typically of metallicity 12 + log(O/H) = 8.70 $\pm$ 0.05, while SDSS dwarfs fainter than M$_R$ = -16 have a mean metallicity of 12 + log(O/H) = 8.28 $\pm$ 0.10, regardless of their luminosity, indicating that there is an approximate floor to the metallicity of low luminosity galaxies. Our hydrodynamical simulations predict that TDGs should have metallicities elevated above the normal luminosity-metallicity relation. Metallicity can therefore be a useful diagnostic for identifying TDG candidate populations in the absence of tidal tails. At magnitudes brighter than M$_R$ ~ -16 our sample of 53 star-forming galaxies in 9 HI gas-rich groups is consistent with the normal relation defined by the SDSS sample. At fainter magnitudes there is an increase in dispersion in metallicity of our sample, suggestive of a wide range of HI content and environment. In our sample we identify three (16% of dwarfs) strong TDG candidates (12 + log(O/H) > 8.6), and four (21%) very metal poor dwarfs (12 + log(O/H) < 8.0), which are likely gas-rich dwarfs with recently ignited star formation.

Year: 2013
Subjects: Information science

description: This presentation at the 2012 Information Architecture Summit, explored the evolution of technology in emergency response, with a special focus on advances in geographic systems, incident management, social media and policy in New York City since September 11, 2001. What technologies do emergency responders in NYC use? How have events like 9/11 and other incidents influenced technology advances? What effect, if any, has the change from a Law Enforcement Mayor to a Media Mayor had on data policy? What are the challenges and opportunities of open government data? How is social media being used in NYC and elsewhere to engage the public in emergency preparedness and response? And, finally, are app contests and hackathons an effective way to improve public services in difficult economic times? The session concluded with a Town Hall discussion of how the IA community can support emergency response efforts throughout each of our own neighborhoods.
