description: We present a novel framework for learning to interpret and generate language using only perceptual context as supervision. We demonstrate its capabilities by developing a system that learns to sportscast simulated robot soccer games in both English and Korean without any language-specific prior knowledge. Training employs only ambiguous supervision consisting of a stream of descriptive textual comments and a sequence of events extracted from the simulation trace. The system simultaneously establishes correspondences between individual comments and the events that they describe while building a translation model that supports both parsing and generation. We also present a novel algorithm for learning which events are worth describing. Human evaluations of the generated commentaries indicate they are of reasonable quality and in some cases even on par with those produced by humans for our limited domain.

description: Background: Pet robots have been employed as viable substitutes to pet therapy in nursing homes. Despite their potential to enhance the psychosocial health of residents with dementia, there is a lack of studies that have investigated determinants of implementing pet robots in real-world practice. This study aims to explore the determinants of implementing pet robots for dementia care in nursing homes, from the perspectives of healthcare professionals and organisational leaders. Methods: A descriptive qualitative study, conceptualised and guided using the Consolidated Framework of Implementation Research (CFIR), was conducted. We conducted semi-structured interviews with healthcare professionals and organisational leaders from nursing homes. Data was transcribed and analysed using Framework Analysis, based on the CFIR as an a priori framework. Results: A total of 22 participants from eight nursing homes were included. Determinants were mapped to constructs from all fve CFIR domains. Determinants relating to the characteristics of pet robots include their design, realisticness and interactivity, afordability, cleanability, perceived evidence strength and comparative advantages to live pets. Determinants relating to external infuences (outer setting) include national regulatory guidelines, funding and networks with other organisations. With regards to characteristics of nursing homes (inner setting), determinants include the relevance of pet robots in relation to the needs of residents with dementia, alignment with care processes, infection control mandates and their relative priority. In the domain characteristics of individuals, determinants were associated with individuals beliefs on the role of technology, desires to enhance residents quality of life, and diferential attitudes on the use of robots. Finally, in the domain implementation process assessments and care planning were identifed as determinants. Conclusions: Overall, while sentiments around determinants within CFIR domains of pet robots characteristics, outer setting and implementation process were similar, participants opinions on the determinants within the ‘inner setting" and characteristics of individuals’ were more varied. This could be due to diferent organisational structures, disciplinary diferences and personal experiences of using pet robots. Many determinants in diferent domains were interrelated. Findings provide a springboard for identifying and designing implementation strategies to guide the translation of pet robots from research into real-world practice.

description: The amount of information generated by a discrete time stochastic processes in a single step can be quantified by the entropy rate. We investigate the differences between two discrete time walk models, the discrete time quantum walk and the classical random walk in terms of entropy rate. We develop analytical methods to calculate and approximate it. This allows us to draw conclusions about the differences between classical stochastic and quantum processes in terms of the classical information theory.

description: This report provides information on (1) pesticide production difficulties in 1974 and 1975 and their effects on pesticide supplies, and (2) pesticide demand estimates for the same years. Producers that accounted for about 75 percent of the basic farm pesticide production in 1971 were surveyed. Regional pesticide distributors covering most of the United States were also contacted for information on pesticide distribution and local availability. Many pesticide producers had difficulty achieving planned output for some pesticides in 1974. Output of about half of the pesticides produced fell below producers' goals, and overall production was about 10 percent below planned output. At the same time, the demand for pesticides increased an estimated 15 percent in 1974 over 1973. Thus, there was a tight supply demand situation with serious shortages of some products. The situation for 1975 is substantially improved with a 10-percent increase in production, but demand is holding at about Iast year's levels. Supplies of most pesticides should be adequate, or nearly so, in 1975. Additional production capacity should be on stream, and raw material shortages should have a smaller impact in 1976.

description: In this contribution we present some results of potential energy surfaces of actinide and transfermium nuclei from multi-dimensional constrained relativistic mean field (MDC-RMF) models. Recently we developed multi-dimensional constrained covariant density functional theories (MDC-CDFT) in which all shape degrees of freedom $β_{λμ}$ with even $μ$ are allowed and the functional can be one of the following four forms: the meson exchange or point-coupling nucleon interactions combined with the non-linear or density-dependent couplings. In MDC-RMF models, the pairing correlations are treated with the BCS method. With MDC-RMF models, the potential energy surfaces of even-even actinide nuclei were investigated and the effect of triaxiality on the fission barriers in these nuclei was discussed. The non-axial reflection-asymmetric $β_{32}$ shape in some transfermium nuclei with $N=150$, namely $^{246}$Cm, $^{248}$Cf, $^{250}$Fm, and $^{252}$No were also studied.

description: We have carried out a search for optically visible post-AGB candidates in the Small Magellanic Cloud (SMC). We used mid-IR observations from the Spitzer Space Telescope to select optically visible candidates with a mid-IR excess. We obtained low-resolution optical spectra for 801 candidates. After removing contaminants and poor quality spectra, the final sample comprised of 63 post-AGB/RGB candidates of A - F spectral type. Using the spectra, we estimated the stellar parameters: effective temperature, surface gravity and [Fe/H]. We also estimated the reddening and deduced the luminosity using the stellar parameters combined with photometry. Based on a luminosity criterion, 42 of these 63 sources were classified as post-RGB candidates and the remaining as post-AGB candidates. From the spectral energy distributions we found that 6 of the 63 post-AGB/RGB candidates have a circumstellar shell suggesting that they are single stars, while 27 of them have a surrounding disc, suggesting that they are binaries. For the remaining candidates the nature of the circumstellar environment was unclear. Variability is displayed by 38 post-AGB/RGB candidates with common variability types being the Population II Cepheids (including RV-Tauri stars) and semi-regular variables. This study has also revealed a new s-process enriched RV Tauri star (J005107.19-734133.3). From the numbers of post-AGB/RGB stars in the SMC, we were able to estimate evolutionary rates that are in good agreement with the stellar evolution models with mass loss in the post-AGB phase and re-accretion in the post-RGB phase. This study also resulted in a new sample of 40 luminous young stellar objects (YSOs) of A - F spectral type. Additionally, we also identified a group of 63 objects whose spectra are dominated by emission lines and in some cases, a UV continuum. These objects are likely to be either hot post-AGB/RGBs or luminous YSOs.

description: Using the small angle neutron scattering (SANS) technique we investigated the vortex lattice (VL) in the mixed state of the stannide superconductor Yb$_{3}$Rh$_{4}$Sn$_{13}$. We find a single domain VL of slightly distorted hexagonal geometry for field strengths between 350 and 18500 G and temperatures between T = 0.05 and T = 6.5 K. We observe a clear in-plane rotation of the VL for different magnetic field directions relative to the crystallographic axes. We also find that the hexagonal symmetry of the VL is energetically favorable in Yb$_{3}$Rh$_{4}$Sn$_{13}$ for external fields oriented along axes of different symmetries: twofold [110], threefold [111] and fourfold [100]. The observed behavior is different from other conventional and unconventional superconductors. The superconducting state is characterized by an isotropic gapped order parameter with an amplitude of $Δ(0)$ = 1.57 $\pm$ 0.05 meV. At the lowest temperatures the field dependence of the magnetic form factor in our material reveals a London penetration depth of $λ_{L}$ = 2508 $\pm$ 17 $Å$ and a Ginzburg coherence length of $ξ$ = 100 $\pm$ 1.3 $Å$, i.e., it is a strongly type-II superconductor, $κ$ = $λ_{L}/ξ$ = 25.

description: Nanofabrication has been long characterized by a top-down approach for the definition of small features starting from large pieces of material. In this contest the process of size scaling in microelectronics devices is based on photolithography that is an advanced top-down technology. In order to design integrated circuits with small features with characteristic dimension below 20 nm, a new kind of approach is needed such as the bottom-up one of self-assembly systems. Indeed symmetric block copolymers are able to spontaneously phase separate into ordered nanoscale lamellar pattern, which can be fruitfully implemented into the fabrication of next generation of microelectronics devices. This thesis offers a systematic study of the thermodynamics and kinetics of the self-assembly process of lamellae forming block copolymers in view of their possible exploitation as lithographic materials.

description: User connectivity patterns in network applications are known to be heterogeneous, and to follow periodic (daily and weekly) patterns. In many cases, the regularity and the correlation of those patterns is problematic: for network applications, many connected users create peaks of demand; in contrast, in peer-to-peer scenarios, having few users online results in a scarcity of available resources. On the other hand, since connectivity patterns exhibit a periodic behavior, they are to some extent predictable. This work shows how this can be exploited to anticipate future user connectivity and to have applications proactively responding to it. We evaluate the probability that any given user will be online at any given time, and assess the prediction on six-month availability traces from three different Internet applications. Building upon this, we show how our probabilistic approach makes it easy to evaluate and optimize the performance in a number of diverse network application models, and to use them to optimize systems. In particular, we show how this approach can be used in distributed hash tables, friend-to-friend storage, and cache pre-loading for social networks, resulting in substantial gains in data availability and system efficiency at negligible costs.

description: We consider the problem of small data global existence for quasilinear wave equations with null condition on a class of Lorentzian manifolds $(\mathbb{R}^{3+1}, g)$ with \textbf{time dependent} inhomogeneous metric. We show that sufficiently small data give rise to a unique global solution for metric which is merely $C^1$ close to the Minkowski metric inside some large cylinder $\{\left.(t, x)\right||x|\leq R\}$ and approaches the Minkowski metric weakly as $|x|\rightarrow \infty$. Based on this result, we give weak but sufficient conditions on a given large solution of quasilinear wave equations such that the solution is globally stable under perturbations of initial data.

description: Human epidermal growth factor (hEGF) is an important therapeutic compound with multiple applications particularly in pharmaceutical industry. Human EGF has already been expressed in different expression systems, however, the production of hEGF with bioactivity in chloroplasts has not been successful so far. In this study, we expressed a 6 × His-tagged hEGF in tobacco chloroplasts in its native conformation for the potential of large-scale production of hEGF for industrial applications. Several transplastomic plant lines were obtained, which were screened by PCR (polymerase chain reaction) using primers specific to selectable gene aadA, hEGF- and GFP-coding sequences that were included in the chloroplast expression vector. The selected lines were confirmed to be homoplasmic by PCR verification and Southern blot analysis. Immunoblotting assays of homoplasmic lines using antibodies raised against hEGF confirmed the accumulation of hEGF in transplastomic plants and the ELISA results demonstrated the expression levels of hEGF were between 0.124% and 0.165% of the total soluble proteins (TSP), namely, 23.16–25.77 ng/g of the fresh weight. In terms of activity, the data from cell proliferation and elongation assays showed that the tobacco-derived recombinant hEGF was as bioactive as its commercial counterpart. To our knowledge, this is the first report of recombinant production of hEGF with native bioactivity form in the chloroplast stroma. Overall, our results demonstrate the potential of higher plant chloroplasts for the production of a human therapeutic, hEGF, in an active conformation.

description: This paper discusses the problem of marrying structural similarity with semantic relatedness for Information Extraction from text. Aiming at accurate recognition of relations, we introduce local alignment kernels and explore various possibilities of using them for this task. We give a definition of a local alignment (LA) kernel based on the Smith-Waterman score as a sequence similarity measure and proceed with a range of possibilities for computing similarity between elements of sequences. We show how distributional similarity measures obtained from unlabeled data can be incorporated into the learning task as semantic knowledge. Our experiments suggest that the LA kernel yields promising results on various biomedical corpora outperforming two baselines by a large margin. Additional series of experiments have been conducted on the data sets of seven general relation types, where the performance of the LA kernel is comparable to the current state-of-the-art results.

description: The article is for illustrative purposes and presents the general situation of price differences in the food chain in theoretical and methodological aspects. The main objective of the research was to assess the market situation of the purchase of agricultural products against a background of prices in retail stores. The research was conducted using the observational method in mid-2021. The subject of the study were the 20 most popular agricultural products, purchased directly from the agricultural producer and through retail chains as products ready for sale unchanged from the moment of purchase. The volatility of prices between different links in the food chain was also determined using Pearson’s linear correlation. The differences in the estimated percentage mark-up of selected retail chains in relation to the obtained values of the price relation index are presented. It was found that the analyzed price differences constituted a complex research problem and were conditioned by many determinants. The relation between the prices offered for agricultural products in purchase and retail prices was often 200%. The main reason for the price differences was the extensive supply chain between the farmer and the chain of stores. The results of the correlation of price volatility allowed to conclude that there was a phenomenon related to the transfer of price risk in the scope of subsequent links of the food chain.

description: We report on Spitzer Space Telescope IRAC observations of near-Earth object (NEO) 2009 BD that were carried out in support of the NASA Asteroid Robotic Retrieval Mission (ARRM) concept. We did not detect 2009 BD in 25 hrs of integration at 4.5 micron. Based on an upper-limit flux density determination from our data, we present a probabilistic derivation of the physical properties of this object. The analysis is based on the combination of a thermophysical model with an orbital model accounting for the non-gravitational forces acting upon the body. We find two physically possible solutions. The first solution shows 2009 BD as a 2.9+/-0.3 m diameter rocky body (rho = 2.9+/-0.5 g cm-3) with an extremely high albedo of 0.85(+0.20/-0.10) that is covered with regolith-like material, causing it to exhibit a low thermal inertia (Gamma = 30(+20/-10) SI units). The second solution suggests 2009 BD to be a 4+/-1 m diameter asteroid with pV = 0.45(+0.35/-0.15) that consists of a collection of individual bare rock slabs (Gamma = 2000+/-1000 SI units, rho = 1.7(+0.7/-0.4) g cm-3). We are unable to rule out either solution based on physical reasoning. 2009 BD is the smallest asteroid for which physical properties have been constrained, in this case using an indirect method and based on a detection limit, providing unique information on the physical properties of objects in the size range smaller than 10 m.

description: The physical aging of supercooled glycerol induced by upward temperature steps of amplitude reaching 45 K was studied by a new method consisting in heating a micrometer-thick liquid film at a rate of up to 60 000 K/s, holding it at a constant high temperature for a controlled duration before letting it quickly cool down to the initial temperature. By monitoring the final slow relaxation of the dielectric loss, we were able to obtain quantitative information on the liquid response to the initial upward step. The so-called TNM (Tool-Narayanaswamy-Moynihan) formalism provided a good description of our observations despite the large distance from equilibrium, provided that different values of the nonlinearity parameter were used for the cooling phase and for the (much further from equilibrium) heating phase. In this form, it allowed to precisely quantify how to design an ideal temperature step, i.e., where no relaxation occurs during the heating phase. It helped bringing a clear physical understanding of how the (kilosecond long) final relaxation is related to the (millisecond long) liquid response to the upward step. Finally, it made possible the reconstruction of the fictive temperature evolution immediately following a step, evidencing the highly non-linear character of the liquid response to such large amplitude temperature steps. This work illustrates both the strengths and limitations of the TNM approach. This new experimental device offers a promising tool to study far-from-equilibrium supercooled liquids through their dielectric response.

description: We perform scanning photocurrent microscopy on WS2 ionic liquid-gated field effect transistors exhibiting high-quality ambipolar transport. By properly biasing the gate electrode we can invert the sign of the photocurrent showing that the minority photocarriers are either electrons or holes. Both in the electron- and the hole-doping regimes the photocurrent decays exponentially as a function of the distance between the illumination spot and the nearest contact, in agreement with a two-terminal Schottky-barrier device model. This allows us to compare the value and the doping dependence of the diffusion length of the minority electrons and holes on a same sample. Interestingly, the diffusion length of the minority carriers is several times larger in the hole accumulation regime than in the electron accumulation regime, pointing out an electron-hole asymmetry in WS2.

description: An expanding universe is not expected to have a static vacuum energy density. The so-called cosmological constant $Λ$ should be an approximation, certainly a good one for a fraction of a Hubble time, but it is most likely a temporary description of a true dynamical vacuum energy variable that is evolving from the inflationary epoch to the present day. We can compare the evolving vacuum energy with a Casimir device where the parallel plates slowly move apart ("expand"). The total vacuum energy density cannot be measured, only the effect associated to the presence of the plates, and then also their increasing separation with time. In the universe there is a nonvanishing spacetime curvature $R$ as compared to Minkowskian spacetime that is changing with the expansion. The vacuum energy density must change accordingly, and we naturally expect $δΛ\sim R\sim H^2$. A class of dynamical vacuum models that trace such rate of change can be constructed. They are compatible with the current cosmological data, and conveniently extended can account for the complete cosmic evolution from the inflationary epoch till the present days. These models are very close to the $Λ$CDM model for the late universe, but very different from it at the early times. Traces of the inherent vacuum dynamics could be detectable in our recent past.

Nature versus Nurture in Complex and Not-So-Complex Systems

description: Understanding the dynamical behavior of many-particle systems both in and out of equilibrium is a central issue in both statistical mechanics and complex systems theory. One question involves "nature versus nurture": given a system with a random initial state evolving through a well-defined stochastic dynamics, how much of the information contained in the state at future times depends on the initial condition ("nature") and how much on the dynamical realization ("nurture")? We discuss this question and present both old and new results for low-dimensional Ising spin systems.

description: We present four new complete mitochondrial genomes for Dasypoda hirtipes, Melitta schultzei, Capicola nanula and Samba griseonigra belonging to the basally branching bee family Melittidae covering four genera in three tribes (Melittini, Hesperaspini, Dasypodaini) and two subfamilies (Melittinae, Dasypodainae). The mitogenomes vary between 15,884 and 20,324 bp in length and consist of the typical set of 13 protein-coding genes, 22 tRNAs, two rRNAs and the control region. These new mitogenomes raise the number of available mitochondrial genomes for the family Melittidae to five and will help to shed light on the phylogenetic relationships within Melittidae and their position within the Anthophila.

description: Purpose: Hyperacusis often leads to debilitating psychosocial consequences, but there is no standard protocol for its diagnosis and management in the United States. In this study, we surveyed U.S. clinical audiologists to understand their education and clinical practices surrounding the evaluation and treatment of hyperacusis.Method: An online survey was distributed to clinical audiologists across the United States. Survey responses were quantified using descriptive statistics and inductive content analysis.Results: Hyperacusis definitions and clinical practice patterns varied widely across the 102 respondents. Respondents cited a lack of education and training as the primary barrier to effective audiological diagnosis and management of hyperacusis, with most respondents reporting ≤ 5 hr of hyperacusis education. Other primary barriers to effective audiological management of hyperacusis included time constraints, reimbursement, poor sensitivity and specificity of available diagnostic tools, and poor efficacy of available treatments and management strategies. Most respondents (82.5%) agreed that audiologists are the primary professionals who are responsible for implementing hyperacusis interventions. However, 63.3% of respondents reported that their clinic does not have a hyperacusis management protocol, and 80.0% routinely recommend treatment that is outside their scope of practice to implement (cognitive behavioral therapy).Conclusions: Clinical audiologists in the United States do not receive uniform education on hyperacusis, and they report multiple barriers to its evidence-based diagnosis and management. Effective hyperacusis management necessitates a multidisciplinary approach. The information obtained via this survey will pave the way toward the refinement of interprofessional education programs and the development of systematic, evidence-based clinical protocols for hyperacusis.Supplemental Material S1.

description: A generally covariant four-dimensional representation of Maxwell's electrodynamics in a generic material medium can be achieved straightforwardly in the metric-free formulation of electromagnetism. In this setup, the electromagnetic phenomena described by two tensor fields, which satisfy Maxwell's equations. A generic tensorial constitutive relation between these fields is an independent ingredient of the theory. By use of different constitutive relations (local and non-local, linear and non-linear, etc.), a wide area of applications can be covered. In the current paper, we present the jump conditions for the fields and for the energy-momentum tensor on an arbitrarily moving surface between two media. From the differential and integral Maxwell equations, we derive the covariant boundary conditions, which are independent of any metric and connection. These conditions include the covariantly defined surface current and are applicable to an arbitrarily moving smooth curved boundary surface. As an application of the presented jump formulas, we derive a Lorentzian type metric as a condition for existence the wave front in isotropic media. This result holds for the ordinary materials as well as for the metamaterials with the negative material constants.

description: This report contains names of foreign parent companies believed to be involved in the U.S. food and fiber system, names and addresses of their U.S. subsidiaries, and an indication of the products they handle. Countries of origin and U.S. addresses are given. Since foreign direct investment in U.S. farming and the food and fiber system is of very recent interest, the list of firms is not exhaustive but provides a basic point of departure for study of the topic.
Electrical Transport Model of Silicene as a Channel of Field Effect Transistor

description: The analytical electrical transport model of the Silicene, a single layer of sp3 bonded silicon atoms in the honeycomb lattice structure as a channel in the field effect transistor configuration is presented in this paper. Although the carrier concentration of the Silicene shows similar behavior to Graphene, there are some differences in the conductance behavior. Presented model shows increment in the total carrier and the conductance with the gate voltage as expected for conventional semiconductors which affected by the temperature only in the neutrality point. The minimum conductance is increased by the temperature whereas it remains stable in the degenerate regime. Presented analytical model is in good agreement with the numerical conductance calculation based on the implementation of the non-equilibrium Greens function method coupled to the density functional theory.
Tests of In-Situ Formation Scenarios for Compact Multiplanet Systems

description: Kepler has identified over 600 multiplanet systems, many of which have several planets with orbital distances smaller than that of Mercury -- quite different from the Solar System. Because these systems may be difficult to explain in the paradigm of core accretion and disk migration, it has been suggested that they formed in situ within protoplanetary disks with high solid surface densities. The strong connection between giant planet occurrence and stellar metallicity is thought to be linked to enhanced solid surface densities in disks around metal-rich stars, so the presence of a giant planet can be a detectable sign of planet formation in a high solid surface density disk. I formulate quantitative predictions for the frequency of long-period giant planets in these in situ models of planet formation by translating the proposed increase in disk mass into an equivalent metallicity enhancement. I rederive the scaling of giant planet occurrence with metallicity as P_gp = 0.05_{-0.02}^{+0.02} x 10^{(2.1 +/- 0.4) [M/H]} = 0.08_{-0.03}^{+0.02} x 10^{(2.3 +/- 0.4) [Fe/H]} and show that there is significant tension between the frequency of giant planets suggested by the minimum mass extrasolar nebula scenario and the observational upper limits. This fact suggests that high-mass disks alone cannot explain the observed properties of the close-in Kepler multiplanet systems and that migration is still a necessary contributor to their formation. More speculatively, I combine the metallicity scaling of giant planet occurrence with recently published small planet occurrence rates to estimate the number of Solar System analogs in the Galaxy. I find that in the Milky Way there are perhaps 4 x 10^6 true Solar System analogs with an FGK star hosting both a terrestrial planet in the habitable zone and a long-period giant planet companion.

description: In this study, we sequenced the complete mitochondrial genome of Gloydius saxatilis using Illumina next-generation sequencing. The total length of the mitogenome was 17,223 bp, and contained 13 protein-coding genes (PCGs), two ribosomal RNAs (rRNAs), 22 transfer RNAs (tRNAs), two non-coding control regions (CRs), and the origin of light (OL)-strand replication. The genome structure and order of the genes were similar to other Crotalinae species. Phylogenetic analysis based on the 13 concatenated PCGs indicated that G. saxatilis closely related to G. intermedius and, G. shedaoensis.
