description: We investigate nonlinear model predictive control (MPC) with terminal conditions in the Koopman framework using extended dynamic mode decomposition (EDMD) to generate a data-based surrogate model for prediction and optimization. We rigorously show recursive feasibility and prove practical asymptotic stability w.r.t. the approximation accuracy. To this end, finite-data error bounds are employed. The construction of the terminal conditions is based on recently derived proportional error bounds to ensure the required Lyapunov decrease. Finally, we illustrate the effectiveness of the proposed data-driven predictive controller including the design procedure to construct the terminal region and controller.

description: We propose Nested LSTMs (NLSTM), a novel RNN architecture with multiple levels of memory. Nested LSTMs add depth to LSTMs via nesting as opposed to stacking. The value of a memory cell in an NLSTM is computed by an LSTM cell, which has its own inner memory cell. Specifically, instead of computing the value of the (outer) memory cell as $c^{outer}_t = f_t \odot c_{t-1} + i_t \odot g_t$, NLSTM memory cells use the concatenation $(f_t \odot c_{t-1}, i_t \odot g_t)$ as input to an inner LSTM (or NLSTM) memory cell, and set $c^{outer}_t$ = $h^{inner}_t$. Nested LSTMs outperform both stacked and single-layer LSTMs with similar numbers of parameters in our experiments on various character-level language modeling tasks, and the inner memories of an LSTM learn longer term dependencies compared with the higher-level units of a stacked LSTM.

description: Oral presentation at PIERS 2019 Rome In this talk the advances on Direct Laser Patterning (DLP) for the synthesis of photo-luminescent semiconductor quantum dots (QDs) belonging to II-VI groups, especially in solid state by using the laser are reported and commented. The implementation of the direct laser patterning (DLP) of QDs is illustrated as a suitable alternative for the fabrication of hybrid organic/inorganic QDs. Two main aspects of the DLP are taken into consideration: the suitable material synthesis and the parameters of laser patterning. On the side of materials particular attention will be dedicated to the synthesis of single source precursors, their decomposition mechanism under thermal and laser treatments. The chemistry of the precursor synthesis is illustrated because their synthesis is a crucial step for the development the direct laser patterning of the QDs. Two examples of precursors of CdS and CdSe QDs will be discussed (Bansal et al., 2015), (Stroea et al., 2015). The synthesis of the CdS and CdSe QDs is first described in solution, then the synthesis of the CdS QDs grown by cadmium bis(dodecanthiolate) and the xanthate precursors by using laser is illustrated. The laser treatment will be discussed in terms of photo-physical and structural properties of the obtained QDs and correlated with the laser conditions. Finally a potential application of this technique together with materials is described in the field of quantum dots light emitting diodes (QD-LEDs) devices. Indeed the DLP technique does not require complex laser systems or the use of dangerous chemical post treatments so it can be introduced as potential method for patterning of pixels for display manufacturing (www.miledi-h2020.eu).

description: This paper aims to unpack the core challenges and opportunities when it comes to building confidence in public authorities making decisions about Canada’s energy future in an age of climate change. It provides an analysis of how Canada’s political and economic context relative to other countries is fundamental to the course of its energy future, and why it is vital that energy and climate decision making be undertaken with that full context in mind. Importantly, the paper underscores that public confidence in those making decisions about Canada’s energy future in an age of climate change – the focus of Positive Energy’s next three years of research and engagement – will be shaped fundamentally by many factors specific to energy (e.g., the role of local and Indigenous governments, the future for oil and gas, social acceptance of energy technologies, and relationships between policymakers, regulators and the courts), but it will also be shaped by a number of political, economic and social trends well beyond energy, climate or environmental issues.

description: Abstract: "Database applications that use multi-terabyte datasets are becoming increasingly important for scientific fields such as astronomy and biology. To improve query execution performance, modern DBMS build indexes and materialized views on the wide tables that store experimental data. The replication of data in indexes and views, however, implies large amounts of additional storage space, and incurs high update costs as new experiments add or change large volumes of data. In this paper we explore automatic data partitioning as a tool to redesign the relational tables in a database for faster sequential access before creating indexes and views. We present AutoPart, a vertical partitioning tool that uses the optimizer's hints to determine optimal partitions for a given workload. According to our experiments, the schemas recommended by AutoPart (a) improve query execution by 12%-44% when compared to the original schema without indexes, (b) execute queries up to 37% faster and updates almost twice as fast compared to the original after indexing. Furthermore, they require half the space for indexes. Finally, we show that a form of categorical partitioning can further improve query performance up to 29%-62% without any indexes and up to 54% with indexes, while update performance improves up to 60%. AutoPart can be used with any commercial database system. Our experimental results are based on the Sloan Digital Sky Survey (SDSS) database, a real-world astronomical database, running on Microsoft's SQL Server 2000."

description: We present a new determination of the large-scale clustering of the CIV forest (i.e., the absorption due to all CIV absorbers) using its cross-correlation with quasars in the Sloan Digital Sky Survey (SDSS) Data Release 12 (DR12). We fit a linear bias model to the measured cross-correlation. We find that the transmission bias of the CIV forest, $b_{Fc}$, at a mean redshift of $z=2.3$, obeys the relation $(1+β_c)b_{F c} = -0.024 \pm 0.003$. Here, $β_{c}$ is the linear redshift space distortion parameter of the CIV absorption, which can only be poorly determined at $β_c=1.1\pm 0.6$ from our data. This transmission bias is related to the bias of CIV absorbers and their host halos through the effective mean optical depth of the CIV forest, $\barτ_c$. Estimating a value $\bar τ_c(z) \simeq 0.01$ from previous studies of the CIV equivalent width distribution, our measurement implies a CIV absorber bias near unity, with a large error due to uncertainties in both $β_c$ and $\barτ_c$. This makes it compatible with the higher DLA bias $b_{\rm DLA}\simeq 2$ measured previously from the cross-correlation of DLAs and the Lyman-$α$ forest. We discuss the implications of the CIV absorber bias for the mass distribution of their host halos. More accurate determinations of $\bar τ_c(z)$ and $β_c$ are necessary to obtain a more robust measurement of this CIV absorber bias.

description: Inverse Uncertainty Quantification (UQ), or Bayesian calibration, is the process to quantify the uncertainties of random input parameters based on experimental data. The introduction of model discrepancy term is significant because "over-fitting" can theoretically be avoided. But it also poses challenges in the practical applications. One of the mostly concerned and unresolved problem is the "lack of identifiability" issue. With the presence of model discrepancy, inverse UQ becomes "non-identifiable" in the sense that it is difficult to precisely distinguish between the parameter uncertainties and model discrepancy when estimating the calibration parameters. Previous research to alleviate the non-identifiability issue focused on using informative priors for the calibration parameters and the model discrepancy, which is usually not a viable solution because one rarely has such accurate and informative prior knowledge. In this work, we show that identifiability is largely related to the sensitivity of the calibration parameters with regards to the chosen responses. We adopted an improved modular Bayesian approach for inverse UQ that does not require priors for the model discrepancy term. The relationship between sensitivity and identifiability was demonstrated with a practical example in nuclear engineering. It was shown that, in order for a certain calibration parameter to be statistically identifiable, it should be significant to at least one of the responses whose data are used for inverse UQ. Good identifiability cannot be achieved for a certain calibration parameter if it is not significant to any of the responses. It is also demonstrated that "fake identifiability" is possible if model responses are not appropriately chosen, or inaccurate but informative priors are specified.

description: Reproductive and viability indicators, among the economic traits of the mulberry silkworm, are important. This article reveals the results of research on the improvement of the unique C-8 ngl breed of Bombyx Mori L. mulberry silkworm balanced on embryonic Z-lethal and sex-limited at egg stage by transmitting high-tech traits of fine silk L-28 simple genetic line. In particular, in the F1 generation of mulberry silkworm, a reciprocal cross with a simple L-28 genetic line was performed. In the F 2 generation, a complex combination in the form of ♀(С-8 ngl × L-28) × ♂(L-28 × С-8 ngl) was obtained. In these studies, a comparative analysis of the parental components obtained in each generation, as well as indicators of reproductive and embryonic viability in F1, F2 generations were implemented. According to the results of the analysis, despite the imbalance of embryonic lethal in F1 generation compared to the C-8 ngl breed taken as a control, a slight decrease in economic traits occurred due to separation. In the F 2 generation, however, it was found that its level had risen to the level of parental components, even higher. In the population of this genotype, it is possible to create an almost new breed by conducting analytical selection from generation to generation.

В этой статье раскрываются результаты исследований по улучшению уникальной породы C-8нгл тутового шелкопряда Bombyx Mori L., сбалансированной по эмбриональному Z-летальному типу и ограниченной по полу на стадии яйца, путем передачи высокотехнологичных признаков простой генетической линии Л-28. В частности, в поколении F1 тутового шелкопряда было проведено реципрокное скрещивание с простой генетической системой Л-28. В поколении F2 была получена сложная комбинация в виде ♀(С-8 нгл×Л-28) × ♂(Л-28×С-8 нгл). В этих исследованиях был проведен сравнительный анализ родительских компонентов, полученных в каждом поколении, а также показателей репродуктивной и эмбриональной жизнеспособности в поколениях F1, F2. Согласно результатам анализа, несмотря на дисбаланс эмбриональной летальности в поколении F1 по сравнению с породой C-8нгл, взятой в качестве контроля, из-за разделения произошло небольшое снижение экономических признаков. Однако в поколении F2 было обнаружено, что его уровень поднялся до уровня родительских компонентов, даже выше. В популяции этого генотипа можно создать практически новую породу, проводя аналитический отбор из поколения в поколение.

description: Introduction: In North America, data over the last decade have found significant morbidity associated with opioid use and prescribing of opioids to patients. The objective of our study was to assess if there has been a change in opioid prescribing practices by emergency physicians over time for undifferentiated abdominal pain. Method: A medical records review for adult patients presenting at two urban academic tertiary care emergency departments was conducted for two distinct time periods; the years of 2012 and 2017. The first 500 patients per year with a discharge diagnosis of “abdominal pain” or “abdominal pain not yet diagnosed” for each year were identified and their charts were reviewed. Data were collected regarding analgesia received in the emergency department and opioid prescriptions written. Opioids were standardized into morphine equivalent doses to compare quantities of prescribed opioids. Results: 1,000 patients were included in our study. The mean age was 42.0 years and 69.6% of patients were female. Comparing 2012 to 2017, there was a non-significant decrease in opioid prescriptions written for patients discharged from the emergency department from 17.8% to 14.4% (p=0.144). Mean opioid quantities per prescription decreased from 130.4 milligrams of morphine equivalents per prescription to 98.9 milligrams per prescription (P=0.002). There was an increase in foundational analgesia use prior to initiating opioids in the emergency department from 17.6% to 26.8% (p=0.001). There was a significant decrease in opioid use in the emergency department from 40.0% to 32.8% (p=0.018). Conclusion: Opioid prescription rates have not changed significantly over our 5-year study period. However, physicians have reduced the quantity prescribed per prescription and are using less opioid analgesia in the emergency department for abdominal pain of undetermined etiology.

description: We qualify the main features of the spectrum of the Hamiltonian of point interaction for a three-dimensional quantum system consisting of three point-like particles, two identical fermions, plus a third particle of different species, with two-body interaction of zero range. For arbitrary magnitude of the interaction, and arbitrary value of the mass parameter (the ratio between the mass of the third particle and that of each fermion) above the stability threshold, we identify the essential spectrum, localise the discrete spectrum and prove its finiteness, qualify the angular symmetry of the eigenfunctions, and prove the increasing monotonicity of the eigenvalues with respect to the mass parameter. We also demonstrate the existence or absence of bound states in the physically relevant regimes of masses.

description: Bosonic quantum error correction codes encode logical qubits in the Hilbert space of one or multiple harmonic oscillators. A prominent class of bosonic codes is that of Gottesman-Kitaev-Preskill (GKP) codes of which implementations have been demonstrated with trapped ions and microwave cavities. In this paper, we investigate theoretically the preparation and error correction of a GKP qubit in a vibrational mode of a neutral atom stored in an optical dipole trap. This platform has recently shown remarkable progress in simultaneously controlling the motional and electronic degrees of freedom of trapped atoms. The protocols we develop make use of motional states and, additionally, internal electronic states of the trapped atom to serve as an ancilla qubit. We compare optical tweezer arrays and optical lattices and find that the latter provide more flexible control over the confinement in the out-of-plane direction, which can be utilized to optimize the conditions for the implementation of GKP codes. Concretely, the different frequency scales that the harmonic oscillators in the axial and radial lattice directions exhibit and a small oscillator anharmonicity prove to be beneficial for robust encodings of GKP states. Finally, we underpin the experimental feasibility of the proposed protocols by numerically simulating the preparation of GKP qubits in an optical lattice with realistic parameters.

description: The PAMELA cosmic ray detector was launched on June 15th 2006 on board the Russian Resurs-DK1 satellite, and during ten years of nearly continuous data-taking it has observed new interesting features in cosmic rays (CRs). In a decade of operation it has provided plenty of scientific data, covering different issues related to cosmic ray physics. Its discoveries might change our basic vision of the mechanisms of production, acceleration and propagation of cosmic rays in the Galaxy. The antimatter measurements, focus of the experiment, have set strong constraints to the nature of Dark Matter. Search for signatures of more exotic processes (such as the ones involving Strange Quark Matter) was also pursued. Furthermore, the long-term operation of the instrument had allowed a constant monitoring of the solar activity during its maximum and a detailed and prolonged study of the solar modulation, improving the comprehension of the heliosphere mechanisms. PAMELA had also measured the radiation environment around the Earth, and it detected for the first time the presence of an antiproton radiation belt surrounding our planet. The operation of Resurs-DK1 was terminated in 2016. In this article we will review the main features of the PAMELA instrument and its constructing phases. Main part of the article will be dedicated to the summary of the most relevant PAMELA results over a decade of observation

description: We study implications of the large-N species solution to the hierarchy problem, proposed by G. Dvali, for reheating of the universe after inflation. Dvali's proposal contains additional N~10^{32} Z_2-conserved quantum fields beyond the Standard Model particles with mass ~1 TeV, which weaken gravity by a factor of 1/N, and thus explain the hierarchy between the Plank scale and the electroweak scale. We show that, in this scenario, the decay rates of inflaton fields through gravitational decay channels are enhanced by a factor of N, and thus they decay into N species of the quantum fields very efficiently, in the limit that quantum gravity effects are unimportant for the gravitational decay rate. In order not to over-reheat the universe, inflaton mass, vacuum expectation value of inflaton, or non-minimal gravitational coupling should be tightly fine-tuned. Our conclusion holds even when the gravitational decay is prohibited by some symmetry of the theory; the universe may still be over-reheated via annihilation of inflatons, if the number density of inflaton quanta is greater than the critical value.

Stabilization of linear systems with multiple unknown time-varying input delays by linear time-varying feedback

description: This paper addresses the stabilization of linear systems with multiple time-varying input delays. In scenarios where neither the exact delays information nor their bound is known, we propose a class of linear time-varying state feedback controllers by using the solution to a parametric Lyapunov equation (PLE). By leveraging the properties of the solution to the PLE and constructing a time-varying Lyapunov-Krasovskii-like functional, we prove that (the zero solution of) the closed-loop system is asymptotically stable. Furthermore, this result is extended to the observer-based output feedback case. The notable characteristic of these controllers is their utilization of linear time-varying gains. Furthermore, they are designed entirely independent of any knowledge of the time delays, resulting in controllers that are exceedingly easy to implement. Finally, a numerical example demonstrates the effectiveness of the proposed approaches.

description: Using the universe of individual asylum cases in the United States from 2000-2004 and a difference-in-differences research design, we test whether Sept. 11, 2001 decreased the likelihood that applicants from Muslim-majority countries were granted asylum. Our estimates suggest that the attacks resulted in a 3.2 percentage point decrease in the likelihood that applicants from Muslim-majority countries are granted asylum. The estimated effect is larger for applicants who share a country of origin with the Sept. 11, 2001attackers. These effects do not differ across judge political affiliation. Our findings provide evidence that emotions affect the decisions of judges.

description: Altmetrics from Altmetric.com are widely used by publishers and researchers to give earlier evidence of attention than citation counts. This article assesses whether Altmetric.com scores are reliable early indicators of likely future impact and whether they may also reflect non-scholarly impacts. A preliminary factor analysis suggests that the main altmetric indicator of scholarly impact is Mendeley reader counts, with weaker news, informational and social network discussion/promotion dimensions in some fields. Based on a regression analysis of Altmetric.com data from November 2015 and Scopus citation counts from October 2017 for articles in 30 narrow fields, only Mendeley reader counts are consistent predictors of future citation impact. Most other Altmetric.com scores can help predict future impact in some fields. Overall, the results confirm that early Altmetric.com scores can predict later citation counts, although less well than journal impact factors, and the optimal strategy is to consider both Altmetric.com scores and journal impact factors. Altmetric.com scores can also reflect dimensions of non-scholarly impact in some fields.

description: A natural strategy for continual learning is to weigh a Bayesian ensemble of fixed functions. This suggests that if a (single) neural network could be interpreted as an ensemble, one could design effective algorithms that learn without forgetting. To realize this possibility, we observe that a neural network classifier with N parameters can be interpreted as a weighted ensemble of N classifiers, and that in the lazy regime limit these classifiers are fixed throughout learning. We call these classifiers the neural tangent experts and show they output valid probability distributions over the labels. We then derive the likelihood and posterior probability of each expert given past data. Surprisingly, the posterior updates for these experts are equivalent to a scaled and projected form of stochastic gradient descent (SGD) over the network weights. Away from the lazy regime, networks can be seen as ensembles of adaptive experts which improve over time. These results offer a new interpretation of neural networks as Bayesian ensembles of experts, providing a principled framework for understanding and mitigating catastrophic forgetting in continual learning settings.

description: When performing precision measurements, the quantity being measured is often perturbed by the measurement process itself. This includes precision frequency measurements for atomic clock applications carried out with Ramsey spectroscopy. With the aim of eliminating probe-induced perturbations, a method of generalized auto-balanced Ramsey spectroscopy (GABRS) is presented and rigorously substantiated. Here, the usual local oscillator frequency control loop is augmented with a second control loop derived from secondary Ramsey sequences interspersed with the primary sequences and with a different Ramsey period. This second loop feeds back to a secondary clock variable and ultimately compensates for the perturbation of the clock frequency caused by the measurements in the first loop. We show that such a two-loop scheme can lead to perfect compensation of measurement-induced light shifts and does not suffer from the effects of relaxation, time-dependent pulse fluctuations and phase-jump modulation errors that are typical of other hyper-Ramsey schemes. Several variants of GABRS are explored based on different secondary variables including added relative phase shifts between Ramsey pulses, external frequency-step compensation, and variable second-pulse duration. We demonstrate that a universal anti-symmetric error signal, and hence perfect compensation at finite modulation amplitude, is generated only if an additional frequency-step applied during both Ramsey pulses is used as the concomitant variable parameter. This universal technique can be applied to the fields of atomic clocks, high-resolution molecular spectroscopy, magnetically induced and two-photon probing schemes, Ramsey-type mass spectrometry, and to the field of precision measurements. Some variants of GABRS can also be applied for rf atomic clocks using CPT-based Ramsey spectroscopy of the two-photon dark resonance.

description: A search for heavy neutral lepton production in $K^+$ decays using a data sample collected with a minimum bias trigger by the NA62 experiment at CERN in 2015 is reported. Upper limits at the $10^{-7}$ to $10^{-6}$ level are established on the elements of the extended neutrino mixing matrix $|U_{\ell 4}|^2$ ($\ell=e,μ$) for heavy neutral lepton mass in the range $170-448~{\rm MeV}/c^2$. This improves on the results from previous production searches in $K^+$ decays, setting more stringent limits and extending the mass range.

Automatically Selecting and Using Primary Effects in Planning: Theory and Experiments

description: The use of primary effects of operators is an effective approach to improving the efficiency of planning. The characterization of “good” primary effects, however, has remained at an informal level and there have been no algorithms for selecting primary effects of operators. We formalize the use of primary effects in planning and present a criterion for selecting useful primary effects, which guarantees efficiency and completeness. We analyze the efficiency of planning with primary effects and the quality of the resulting plans. We then describe a learning algorithm that automatically selects primary effects and demonstrate, both analytically and empirically, that the use of this algorithm significantly reduces planning time and does not compromise completeness.

description: Lead-halide perovskites have been attracting attention for potential use in solid-state lighting. Following the footsteps of solar cells, the field of perovskite light-emitting diodes (PeLEDs) has been growing rapidly. Their application prospects in lighting, however, remain still uncertain due to a variety of shortcomings in device performance including their limited levels of luminous efficiency achievable thus far. Here we show high-efficiency PeLEDs based on colloidal perovskite nanocrystals (PeNCs) synthesized at room temperature possessing dominant first-order excitonic radiation (enabling a photoluminescence quantum yield of 71% in solid film), unlike in the case of bulk perovskites with slow electron-hole bimolecular radiative recombination (a second-order process). In these PeLEDs, by reaching charge balance in the recombination zone, we find that the Auger nonradiative recombination, with its significant role in emission quenching, is effectively suppressed in low driving current density range. In consequence, these devices reach a record high maximum external quantum efficiency of 12.9% reported to date and an unprecedentedly high power efficiency of 30.3 lm W-1 at luminance levels above 1000 cd m-2 as required for various applications. These findings suggest that, with feasible levels of device performance, the PeNCs hold great promise for their use in LED lighting and displays.

Risk Sharing in a Dual Labor Market

Dynamic contracts
Limited commitment
Employment protection legislation

description: In OECD countries, the labor market features a coexistence of open-ended, permanent jobs subject to strict employment protection and fixed-term, temporary contracts. This paper introduces a search-and-matching model of a dual labor market - divided between permanent and temporary jobs - with risk aversion and dynamic employment contracts. Optimal contracting entails a trade-off between commitment and the flexibility of separation, a novel rationale for the coexistence of permanent and temporary jobs. The paper shows that this coexistence emerges when (i) firms find it optimal to provide insurance to workers, (ii) the firms' commitment ability is limited, and (iii) the match-quality distribution has enough dispersion. In this setup, firing costs are potentially associated with welfare gains for both employed and unemployed workers.

description: The mass transfer process is prevalent during the inspiral phase of compact binary systems. Our study focuses on systems comprising low-mass white dwarfs, particularly in neutron star-white dwarf binaries and double white dwarf binaries, where a stable mass transfer process occurs at low frequencies. By analyzing the evolution of gravitational wave frequencies in the presence of mass transfer within quasi-circular orbits, we derive an analytical expression for the time-dependent frequency across different frequency bands and the waveforms emitted by compact binaries. Considering gravitational waves emitted by compact binaries in the $1\thicksim10$ mHz band, based on the Fisher analysis, we find that the mass transfer rate can be measured as accurately as $10^{-7} M_\odot/\text{year}$ by space-based gravitational-wave detectors with a signal-to-noise ratio of the order of $10^3$. Including the mass transfer effect in the waveforms provides a new possibility to measure the individual masses of double white dwarf binaries. The relative error of measured white dwarf masses can be down to the order of $0.01$.
