description: Measurements of the time-dependent CP asymmetry in the decay $B^0_d (t) \to π^+ π^-$ and its charge conjugate by the BELLE and BABAR collaborations currently yield $C_{ππ}^{+-} = -0.46 \pm 0.13$ and $S_{ππ}^{+-} = -0.74 \pm 0.16$, characterizing the direct and mixing-induced CP asymmetries, respectively. We study the implication of these measurements on the CKM phenomenology taking into account the available information in the quark mixing sector. Our analysis leads to the results that the ratio $|P_c/T_c|$ involving the QCD-penguin and tree amplitudes and the related strong phase difference $δ_c = δ_c^P - δ_c^T$ in the $B^0_d/\bar{B}_d^0 \to π^+ π^-$ decays are quite substantial. Using the isospin symmetry to constrain $|P_c/T_c|$ and $\cos (2θ)$, where $2 θ$ parameterizes the penguin-induced contribution, we present a fit of the current data including the measurements of $S_{ππ}^{+-}$ and $C_{ππ}^{+-}$. Our best-fits yield: $α= 92^\circ$, $β= 24^\circ$, $γ= 64^\circ$, $|P_c/T_c| = 0.77$, and $δ_c = -43^\circ$. At 68% C.L., the ranges are: $81^\circ \leq α\leq 103^\circ$, $21.9^\circ \leq β\leq 25.5^\circ$, $54^\circ \leq γ\leq 75^\circ$, $0.43 \leq |P_c/T_c| \leq 1.35$ and $-64^\circ \leq δ_c \leq -29^\circ$. Currently {\it en vogue} dynamical approaches to estimate the hadronic matrix elements in $B \to ππ$ decays do not provide a good fit of the current data.

description: We present a model/executable specification of smart contract execution in Coq. Our formalization allows for inter-contract communication and generalizes existing work by allowing modelling of both depth-first execution blockchains (like Ethereum) and breadth-first execution blockchains (like Tezos). We represent smart contracts programs in Coq's functional language Gallina, enabling easier reasoning about functional correctness of concrete contracts than other approaches. In particular we develop a Congress contract in this style. This contract -- a simplified version of the infamous DAO -- is interesting because of its very dynamic communication pattern with other contracts. We give a high-level partial specification of the Congress's behavior, related to reentrancy, and prove that the Congress satisfies it for all possible smart contract execution orders.

description: The goal of this paper is to present a method for simultaneous trajectory and local stabilizing policy optimization to generate local policies for trajectory-centric model-based reinforcement learning (MBRL). This is motivated by the fact that global policy optimization for non-linear systems could be a very challenging problem both algorithmically and numerically. However, a lot of robotic manipulation tasks are trajectory-centric, and thus do not require a global model or policy. Due to inaccuracies in the learned model estimates, an open-loop trajectory optimization process mostly results in very poor performance when used on the real system. Motivated by these problems, we try to formulate the problem of trajectory optimization and local policy synthesis as a single optimization problem. It is then solved simultaneously as an instance of nonlinear programming. We provide some results for analysis as well as achieved performance of the proposed technique under some simplifying assumptions.

description: Nonalcoholic fatty liver disease (NAFLD) is associated with substantial morbidity, mortality, and economic burden. With currently no approved treatment, an effective pharmaceutical intervention for this disease must be both clinically- and cost-effective. A Markov model was constructed to estimate the clinical outcomes, costs, and quality of life impact of a hypothetical pharmaceutical intervention. Lifetime clinical outcomes, life-years, quality-adjusted life-years (QALYs), costs (2020 $US), incremental cost-effectiveness ratios (ICERs), and economically justifiable prices (EJPs) were quantified. Only patients with fibrosis stage F2–F4 were assumed eligible to initiate pharmaceutical treatment. Over a mean life expectancy of approximately 21 years in the simulated cohort, drug treatment reduced liver-related mortality by 6.0% (2.7% absolute reduction). Assuming an annual drug cost of $36,000, total discounted medical costs were $574,238 and $120,312 for drug and usual care, respectively, with discounted QALYs estimated to be 9.452 and 9.272 for the two comparators. This yielded an ICER of $2,517,676/QALY gained. The EJP of the drug at an ICER threshold of $150,000/QALY gained was $2,633, a 93% reduction from a base case. Sensitivity analyses suggest that, without a substantial decrease in the drug price, ICERs would exceed $500,000/QALY gained even with the most favorable efficacy assumptions. For a pharmaceutical intervention to be considered cost-effective in the NAFLD fibrosis population, the substantial clinical benefit will need to be coupled with a modest annual price. Annual drug costs exceeding $12,000 likely will not provide reasonable value, even with favorable efficacy. More work is needed to estimate the cost-effectiveness of lifestyle modifications.

description: Documentation is an essential component of good data management and yet data service providers often struggle to provide effective support to researchers. There are materials available for creating or assisting researchers with documentation at the beginning and end of a project; from data management plans to documenting data for archival purposes. However, we don't yet have a solid understanding of how research teams incorporate (or not) documentation into their everyday work. This poster reports on a project to investigate, analyze, and synthesize real and ideal documentation practices within research teams in order to develop a universal project manual documentation template. It is our contention that a "lab manual" or "project organization protocol" will enhance the effectiveness and efficiency of research teams, while creating an inclusive environment by making local practices and expectations clear to all team members regardless of previous research experience and disciplinary background. The goal of this project is to identify the basic considerations that any researcher from any discipline should consider for their local documentation in support of team-based research projects.

 TYPE SPECIES: Rhyncomyia braunsi Villeneuve, 1920 a, by original designation.
NOTES: The two described species are restricted to the Afrotropical Region (Pont 1980: 783).
 Pseudorhyncomyia braunsi (Villeneuve, 1920b: 158) (Rhynchomyia).
Fig. 104.
TYPE LOCALITY: South Africa (Cape)
DISTRIBUTION: Namibia *, South Africa (Cape, Natal) and Tanzania.
MATERIAL: 1♂, Hungorob ravine at(1): 6.viii.2000, Meakin/Raleigh Int. (LT) Bberg UV 52.
 NOTES: Ferrar (1987: 90) notes that larvae of P. braunsi were found in South Africa in the rubbish heaps of harvester termites of the genus Hodotermes Hagen (Hodotermitidae), which accumulate on the soil surface, near the opening of subterranean nests. Larvae were noted to attack live termites that approach the heaps and were successfully reared on live termites in culture. Pupariation was noted to occur under the heaps. In Namibia the species has only been collected at UV­light at low elevation on the Brandberg (700 m) in August. Currently only known from the Brandberg Massif on the edge of the nama­karoo biome (Fig. 104).

description: Dynamic scene understanding is an essential capability in robotics and VR/AR. In this paper we propose Co-Section, an optimization-based approach to 3D dynamic scene reconstruction, which infers hidden shape information from intersection constraints. An object-level dynamic SLAM frontend detects, segments, tracks and maps dynamic objects in the scene. Our optimization backend completes the shapes using hull and intersection constraints between the objects. In experiments, we demonstrate our approach on real and synthetic dynamic scene datasets. We also assess the shape completion performance of our method quantitatively. To the best of our knowledge, our approach is the first method to incorporate such physical plausibility constraints on object intersections for shape completion of dynamic objects in an energy minimization framework.

description: The dynamics of phase separation in multi-component bilayer fluid vesicles is investigated by means of large-scale dissipative particle dynamics. The model explicitly accounts for solvent particles, thereby allowing for the very first numerical investigation of the effects of hydrodynamics and area-to-volume constraints. We observed regimes corresponding to coalescence of flat patches, budding and vesiculation, and coalescence of caps. We point out that the area-to-volume constraint has a strong influence on crossovers between these regimes.

description: The objective of this study was to assess the face validity of a disease model evaluating the cost-effectiveness of ataluren for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD). This was a Delphi panel study comprising of physicians with first-hand experience of ataluren for the treatment of nmDMD. Consensus was sought for previously unvalidated model data, including patient health status and quality of life measured using the Health Utility Index (HUI), mortality, informal caregiving, and the expected benefit of early ataluren treatment across four states: (1) ambulatory, (2) non-ambulatory, not yet requiring ventilation support, (3) non-ambulatory, night-time ventilation support, and (4) non-ambulatory, full-time ventilation support. Nine experts from five countries participated in the Delphi panel. Consensus was obtained for all questions after three panel rounds (except for two HUI-questions concerning hand function [dexterity]). Consensus HUI-derived utilities for state (1) were 1.0000 for ataluren on top of best supportive care (BSC) and 0.7337 for BSC alone. Corresponding estimates for state (2) were 0.3179 and 0.2672, for state (3) 0.1643 and 0.0913, and for state (4) −0.0732 and −0.1163. Consensus mortality rates for states (1), (2), and (3) were 4%, 13%, and 33%, and life expectancy in state (4) was agreed to be 3 years. Panelists further agreed that two informal caregivers typically provide day-to-day care/support to patients with nmDMD, and that starting treatment with ataluren at 2 versus 5 years of age would be expected to delay loss of ambulation by an additional 2 years, and initiation of night-time and full-time ventilation support by an additional 3 years, respectively. The main limitation concerns the size of the Delphi panel, govern primarily by the rarity of the disease. This study confirms the face validity of key clinical parameters and assumptions underlying the ataluren cost-effectiveness model.

description: The atomic recombination process leads to a softening of the matter equation of state as reflected by a reduced generalized adiabatic index, with accompanying heat release. We study the effects of this recombination softening and reheating of the cosmic plasma on the ionization history, visibility function, Cold Dark Matter (CDM) transfer function, and the Cosmic Microwave Background (CMB) spectra. The resulting modifications of the CMB spectrm is 1/10 of WMAP's current error and is comparable to PLANCK's error. Therefore, this effect should be considered when data with higher accuracy are analysed.

description: Driven non-linear resonators can display sharp resonances or even multistable behaviours amenable to induce strong enhancements of weak signals. Such enhancements can make use of the phenomenon of vibrational resonance whereby a weak low-frequency signal applied to a bistable resonator can be amplified by driving the non-linear oscillator with another appropriately-adjusted non-resonant high-frequency field. Here we demonstrate the resonant enhancement of a weak signal by use of a vibrational force yet in a monostable system consisting of a driven nano-electromechanical nonlinear resonator. The oscillator is subjected to a strong quasi-resonant drive and to two additional tones: a weak signal at lower frequency and a non-resonant driving at an intermediate frequency. We show experimentally and theoretically a significant enhancement of the weak signal thanks to the occurence of vibrational resonance enabled by the presence of the intermediate frequency driving. We analyse this phenomenon in terms of coherent nonlinear resonance manipulation. Our results illustrate a general mechanism which may have applications in the fields of radio-frequency signal processing or sensing for instance.

description: We assessed healthcare resource utilization (HCRU) and costs of cardiovascular (CV) events in patients with a history of atherosclerotic cardiovascular disease (ASCVD) in Germany. We conducted a retrospective matched case-control study based on German claims data from 1 January 2012 to 31 December 2017 using the “Institute for Applied Health Research Berlin” (InGef) Research Database. Cases who had a myocardial infarction (MI), stroke and angina pectoris identified by ICD-10-GM codes between 1 January 2014 and 31 December 2016 were matched to event-free controls by an exact matching approach without replacement at a ratio of 1:2. Costs and HCRU were assessed in individual 1-year follow-up periods after the index event for the overall cohort and subgroups of MI cases and stroke cases. The overall cohort consisted of a total of 14,169 cases with a CV index event matched to 28,338 controls. The mean age of the overall cohort was 73.3 years, 34.1% of the patients were female, 3,717 (26.2%) had an MI, and 3,752 (26.5%) had stroke. Following the index events, 12.2% of cases in the overall cohort, 12.6% of MI cases, and 8.7% of stroke cases experienced a recurrent CV event. CV cases had on average 1.7 more all-cause hospitalizations (p <0.001) and 6.1 more outpatient visits (p <0.001) during the 1-year follow-up period than did controls. In the MI and stroke subgroups, cases had on average 1.8 and 1.6 more all-cause hospitalizations and 7.0 and 4.0 more outpatient visits, respectively (differences were statistically significant). Compared to controls, cases incurred on average higher total healthcare costs: by €11,898 for overall cases, by €16,349 for MI, and by €14,360 in stroke cases (overall: p <0.001; MI: p <0.001; stroke: p <0.001). CV events in ASCVD patients pose a considerable clinical burden on patients and cause significant costs for the German statutory healthcare system.

In the absence of the central obstruction cylinders of low aspect-ratio exhibit tetratic order, except for the existence of four defects which restore the symmetry broken by the circular confinement. This behaviour is demanded by topology in systems with strong anchoring properties at the surface. By contrast, topology dictates that the annular geometry is compatible with a distorted tetratic phase without point defects. However, the effect of restricted geometry and limited size on phases possessing finite anchoring energy at the wall and elastic stiffness leads to different configurations, showing finite ordered regions separated by domain walls. We argue that highly packed nonequilibrium vibrated granular monolayers respond to geometrical frustration and extreme confinement as corresponding equilibrium systems of particles do, and that the former can be analysed in terms of surface free energies, elastic distortions and defects, much as equilibrium liquid crystals. Therefore, selective confinement of vertically-vibrated monolayers of rods could be used with advantage as a new tool to study the creation and dynamics of various types of defects in ordered systems.

description: Architecture, especially housing, serves as a vessel for life. It is also a reflection of inhabitants’ personalities, interests and lifestyles, which would be very diverse. Although current housing design can meet the needs and demands of most people, it is still based on the architect’s and designers’ imagination, and users are abstracted as a series of data. This approach overlooks social diversity and fails to respond adequately to different or evolving needs. My thesis explores one possibility/a new typology of housing in the future when the science and technology is highly developed including building materials and machinery. It allows users to personalize their living space and gives individuals more freedom to choose and design their space, thereby improving the efficiency and comfort of space use. This project is also a tribute to the Metabolism idea in architecture.

description: Effects of the interchannel coupling on the spin polarization of energetic photoelectrons emitted from atomic Ne valence subshells are examined. Like previously obtained results for cross sections and angular distributions, the photoelectron spin polarization parameters too are found considerably influenced by the coupling. The result completes a series of studies to finally conclude that the independent particle description is inadequate for the {\em entire} range of photoionization dynamics over the {\em full} spectral energy domain

description: The weighted kappa coefficient of a binary diagnostic test is a measure of the beyond chance agreement between the diagnostic test and the gold standard, and depends on the sensitivity and the specificity of the diagnostic test, on the disease prevalence and on the relative importance between the false positives and the false negatives. This manuscript studies a hypothesis test to compare the weighted kappa coefficients of two binary diagnostic tests when, in the presence of partial disease verification, a discrete covariate is observed in all individuals. The EM algorithm is applied to estimate the weighted kappa coefficients and the SEM algorithm is applied to estimate their variances-covariances. Simulation experiments were carried out to study the size and the power of the proposed hypothesis test. The results were applied to a real example on the diagnosis of the Alzheimer’s disease.

description: We have developed a new material for neutron shielding applications where space is restricted. W$_2$B is an excellent attenuator of neutrons and gamma-rays, due to the combined gamma attenuation of W and neutron absorption of B. However, its low fracture toughness (~3.5 MPa$\cdot$m$^{0.5}$) and high melting point (2670 °C) prevent the fabrication of large fully-dense monolithic parts with adequate mechanical properties. Here we meet these challenges by combining W$_2$B with a minor fraction (43 vol.%) of metallic W. The material was produced by reaction sintering W and BN powders. The mechanical properties under flexural and compressive loading were determined up to 1900 °C. The presence of the ductile metallic W phase enabled a peak flexural strength of ~950 MPa at 1100 °C, which is a factor of 2-3 higher than typical monolithic transition-metal borides. Its ductile-brittle transition temperature of ~1000 °C is typical of W-based composites, which is surprising as the W phase was the minor constituent and did not appear to form a fully continuous network. Compression tests showed hardening below ~1500 °C and significant elongation of the phase domains, which suggest that by forging or rolling, further improvements in ductility may be possible.

description: Researchers and teacher educators use video records of practice documenting classroom activity to study and improve upon teaching across grade levels and subject areas.nbsp; Their usage of video records of practice is often accompanied by the use of supplemental data, such as school/classroom demographics, seating charts, lesson plans, and interviews, to achieve research or teaching aims.nbsp; Educational researchers use these data as case studies, to test research questions and framework, and to develop research protocols.nbsp; Teacher educators use the data as teaching exemplars, to allow pre-service teachers to practice and evaluate teaching methods, and reflect upon pedagogy.nbsp; This poster will evaluate patterns in the use of supplemental data usage by researchers, teacher educators, and those who use video records of practice for research and teaching depending on the purpose of that data reuse.nbsp; The results of this analysis will provide a baseline for how and what supplemental data will meet the research and/or teaching needs of schools of education. The findings also have implications for repositories' data collection strategies and how best to make video records of practice available to these designated communities.

 Diagnosis: Head with medial carina between antennal socket and median ocellus (Fig. 79). Metasomal tergum 2 sharply folded above spiracle, separating tergum into medio­ and laterotergites (the fold caused by break in the cuticle not only by a change in cuticle thickness) (Figs. 4–9, 77, 78). Hind wing subbasal cell large: vein 1M 0.9–1.7 times as long as vein cu­a (Fig. 66).
The following characters apply to specimens of almost all species. Metasomal tergum 1 with lateral margins meeting ventrally in basal 0.1–0.5 (Fig. 70). Fore wing with radial cell more than 0.5 times maximum width of stigma (Figs. 52, 57–63), and wing densely pubescent (Figs. 52, 54).
The occipital carina development mentioned in Shaw (1997) is variable and is not used further.
This is a large worldwide genus. All reared specimens are from Miridae.
  Peristenus digoneutis group.  Adults show a wide range of colour patterns, but all have the occipital carina widely interrupted dorsally (this character may be hidden in some specimens with the head inclined upward) (Fig. 32). The three included species, P. digoneutis, P. relictus (Ruthe) and P. rubricollis (Thomson), were intentionally introduced and established for biological control of Lygus and Adelphocoris plant bugs.

description: To develop a model to evaluate the cost-effectiveness of 4 mg dibotermin alfa/absorbable collagen sponge (ACS) versus iliac crest bone graft (ICBG) in patients with lumbar degenerative disc disease in the United Kingdom. A Markov decision-analytic model was constructed to calculate costs and quality-adjusted life-years over a 4-year time horizon in each treatment group, from a United Kingdom National Health Service perspective. An individual patient data meta-analysis was undertaken to synthesize data from four randomized controlled trials and two single-arm studies concerning health-related quality of life and procedural resource use. Current cost data from the United Kingdom were then applied to determine the overall mean cost per patient in each group. One-way and probabilistic sensitivity analyses were undertaken to explore the impact of parameter uncertainty. The model predicted 4-year discounted cost savings of £192 per patient treated with dibotermin alfa/ACS, compared with ICBG, and a gain of 0.0114 QALYs per patient over the same time period. Sensitivity analyses indicated that the results were most sensitive to variability in the differences in health-related quality of life and secondary surgery rate, with dibotermin alfa/ACS having a 60% probability of being cost-effective at a willingness-to-pay threshold of £20,000 per QALY gained. There is uncertainty in the difference in cost and QALYs between the two groups. However, comprehensive sensitivity analyses were undertaken to explore this and present the results in a transparent manner. Our results provide an economic case for the use of 4 mg dibotermin alfa/ACS versus iliac crest bone graft, with additional health benefits predicted at reduced overall cost.

description: From the analysis of light (anti)nuclei multiplicities that were measured recently by the ALICE collaboration in Pb+Pb collisions at the center-of-mass collision energy $\sqrt{s_{NN}} =2.76$ TeV there arose a highly non-trivial question about the excluded volume of composite particles. Surprisingly, the hadron resonance gas model (HRGM) is able to perfectly describe the light (anti)nuclei multiplicities under various assumptions. Thus, one can consider the (anti)nuclei with a vanishing hard-core radius (as the point-like particles) or with the hard-core radius of proton, but the fit quality is the same for these assumptions. It is clear, however, that such assumptions are unphysical. Hence we obtain a formula for the classical excluded volume of loosely bound light nuclei consisting of A baryons. To implement a new formula into the HRGM we have to modify the induced surface tension concept to treat the hadrons and (anti)nuclei on the same footing. We perform a simultaneous analysis of hadronic and (anti)nuclei multiplicities measured by the ALICE collaboration. The HRGM with the induced surface tension allows us to verify different assumptions on the values of hard-core radii and different scenarios of chemical freeze-out of light (anti)nuclei. It is shown that the unprecedentedly high quality of fit $χ^2_{tot}/dof \simeq 0.769$ is achieved, if the chemical freeze-out temperature of hadrons is about $T_h=150$ MeV, while the one for all (anti)nuclei is $T_A=174-175.2$ MeV.

A direct derivation of the dark soliton excitation energy

description: Dark solitons are common topological excitations in a wide array of nonlinear waves. The dark soliton excitation energy, crucial for exploring dark soliton dynamics, is necessarily calculated in a renormalized form due to its existence on a finite background. Despite its tremendous importance and success, the renormalized energy form was firstly only suggested with no detailed derivation, and was then "derived" in the grand canonical ensemble. In this work, we revisit this fundamental problem and provide an alternative and intuitive derivation of the energy form from the fundamental field energy by utilizing a limiting procedure that conserves number of particles. Our derivation yields the same result, putting therefore the dark soliton energy form on a solid basis.
