description: Span programs are an important model of quantum computation due to their tight correspondence with quantum query complexity. For any decision problem $f$, the minimum complexity of a span program for $f$ is equal, up to a constant factor, to the quantum query complexity of $f$. Moreover, this correspondence is constructive. A span program for $f$ with complexity $C$ can be compiled into a bounded error quantum algorithm for $f$ with query complexity $O(C)$, and vice versa. In this work, we prove an analogous connection for quantum time complexity. In particular, we show how to convert a quantum algorithm for $f$ with time complexity $T$ into a span program for $f$ such that it compiles back into a quantum algorithm for $f$ with time complexity $\widetilde{O}(T)$. While the query complexity of quantum algorithms obtained from span programs is well-understood, it is not generally clear how to implement certain query-independent operations in a time-efficient manner. We show that for span programs derived from algorithms with a time-efficient implementation, we can preserve the time efficiency when implementing the span program. This means in particular that span programs not only fully capture quantum query complexity, but also quantum time complexity. One practical advantage of being able to convert quantum algorithms to span programs in a way that preserves time complexity is that span programs compose very nicely. We demonstrate this by improving Ambainis's variable-time quantum search result using our construction through a span program composition for the OR function.

Harriet Martineau’s Early Fiction and Hartleian Psychology

Subjects: Uncategorized

description: Harriet Martineau’s (1802-1876) most famous work of fiction, Deerbrook (1839) has attracted critical attention as the novel which initiated the trend towards domestic realism in the nineteenth-century novel. One feature of domestic realism was its psychological insight into the hidden motives and feelings of the characters. This thesis focuses on the influence of the associationist psychology of David Hartley (1705-1757) on Martineau’s early fiction. Although associationism is known today as an archaic psychological theory characterized by its mechanistic views of the mind, the young Martineau was inspired by Hartley’s prophetic vision of the progress of humanity developed in the second part of his Observations on Man (1749), which contributed to a religious superstructure for his whole theory. Hartley’s influence is traceable in her lesser known works of fiction and essays written in her formative years from the mid 1820s to the early 1830s. These consist of short didactic tales for young readers and essays for the Monthly Repository, a sectarian periodical supported by the Unitarians within whose intellectual networks Martineau was brought up. By examining these tales and essays, one can discern not only the process of her development as a writer of fiction but also the centrality of Hartleian theory in formulating her fundamental views on human mind, which prepared the way for the major success of her Illustrations of Political Economy (1832-34). Whereas the interiority of her characters was presented much more skillfully in the Illustrations and Deerbrook than in the earlier fiction, her basic tenets concerning human mind and its proper management were unchanged. In its bold representation of the characters’ hidden passions and conflicts Deerbrook represents the culmination of Martineau’s exploration of the mind guided by Hartleian psychology.

description: The present paper derives the post-Newtonian Lagrangian of translational motion of N arbitrary-structured bodies with all mass and spin multipoles in a scalar-tensor theory of gravity. The multipoles depend on time and evolve in accordance with their own dynamic equations of motion. The Lagrangian is retrieved from the post-Newtonian equations of motion by solving the inverse problem of the Lagrangian mechanics and generalizes a well-known Lagrangian of pole-dipole-quadrupole massive particles to the particles of higher multipolarity. Analytic treatment of the higher-order multipole contributions is important for more rigorous computation of gravitational waveform of inspiralling compact binaries at the latest stage of their orbital evolution before merger when tidal and rotational deformations of stars are no longer small and rapidly change in time. The Lagrangian of an N-body system with arbitrary mass and spin multipoles is instrumental for formulation of the post-Newtonian conservation laws of energy, momenta and the integrals of the center of mass.

description: Effects of sampling error in estimation of farmers’ mean yields for crop insurance purposes and their implications for actuarial soundness are explored using farm-level corn yield data in Iowa. Results indicate that sampling error, combined with nonlinearities in the indemnity function, leads to empirically estimated insurance rates that exceed actuarially fair values. The difference depends on the coverage level, the number of observations used, and the participation strategy followed by farmers. A new estimator for mean yields based on the decomposition of farm yields into systemic and idiosyncratic components is proposed, which could lead to improved rate-making and reduce adverse selection.

description: Understanding what happens inside the rippling and dancing surface of a liquid remains one of the great challenges of fluid dynamics. Using molecular dynamics (MD) we can pick apart the interface structure and understand surface tension. In this work we derive an exact mechanical formulation of hydrodynamics for a liquid-vapour interface using a control volume which moves with the surface. This mathematical framework provides the local definition of hydrodynamic fluxes at any point on the surface. These are represented not only by the flux of molecules and intermolecular interactions acting across the surface, but also as a result of the instantaneous local curvature and movement of the surface itself. By explicitly including the surface dynamics in the equations of motion, we demonstrate an exact balance between kinetic and configurational pressure normal to the surface. The hydrodynamic analysis makes no assumptions regarding the probability distribution function, so is valid for any system arbitrarily far from thermodynamic equilibrium. The presented equations provide a theoretical basis for the study of time-evolving interface phenomena such as bubble nucleation, droplet dynamics and liquid-vapour instabilities.

description: Consistency of functional characteristics in wheat is a concern confronting buyers and sellers. This research analyzes the cost and risk of different procurement strategies for importers. A stochastic simulation model is used to determine the probability of functional characteristics being satisfied subject to quality targets and costs for alternative purchase strategies. Stochastic efficiency was employed to identify purchase strategies that dominate others and to determine the extent of preference. As more specific characteristics are incorporated into a contract, results indicate that the probabilities of meeting end-use requirements increase

description: Informal construction has been rife in Albanian cities since the fall of communism in 1990. This study investigates the fluctuations in the housing legalization process in conjunction with national and local elections in Albania from 2008 to 2021. Government revenues from legalization fees are used as a proxy for the pace of the legalization process. The key finding is that the legalization of informal buildings intensifies prior to an election and drops afterwards, suggesting that the process is politically driven. This phenomenon is termed Election-Driven Legalization of Informality (EDLI) and is part and parcel of the shadow economy in urban Albania. In combination with another phenomenon known as Election-Driven Informality (EDI), EDLI produces a vicious circle. First, informal construction is enabled or tolerated before an election to curry favor with voters; that is EDI at work. Then, EDLI comes into play: before the next election, the informal buildings are legalized in a rush, again for the purpose of garnering voter support. These practices, which are perpetrated by both sides of the political spectrum, are both unethical and unsustainable.
Seated postural control in typically developing children and in children with traumatic brain injury
Creators: name: Ott, Beth Margaret
Publisher: name: University of British Columbia
Year: 2009

description: Purpose: Seated postural control is important for children with and without disabilities and is a requirement for many occupational, functional, and recreational activities. Traumatic brain injury (TBI) is the most frequent diagnosis of all traumatic injuries reported in children and often results in multiple limitations in function, however, there have been no studies on the seated postural control in these children. The objectives of this study were to evaluate the (1) seated postural control of typically developing children, including the test-retest reliability of these measures, and (2) seated postural control of children with severe TBI during re-acquisition of independent sitting. Methods: Ten typically developing children were assessed on two separate occasions and two children with TBI (6 and 15 year old males) were assessed longitudinally. For all tests, children sat on a force plate on top of a raised bench which could be translated forward or backward. Surface EMG electrodes recorded bilateral trunk and leg muscle activity. The static, volitional, and reactive postural control of the children was assessed during quiet sitting, self-paced maximal leans, and platform translations, respectively. Intraclass correlation coefficients were used to determine the test-retest reliability of the postural control in typically developing children. Correlations were calculated to determine the effects of age on the postural control of typically developing children. Analysis of the postural control data in the children with TBI was descriptive. Results: There was moderate to high test-retest reliability for all measures of postural control in the typically developing children. A statistically significant correlation was found between age and the static postural measure in the typically developing children. Initially, the postural control of the children with TBI differed considerably from that of the typically developing children. Over time, the postural control of the children with TBI improved but still differed from that of the typically developing children. Conclusions: Measures of seated postural control of typically developing children were reliable. The effects of age on these measures are dependent on the type of postural control. The recovery of seated postural control in children with TBI occurs in all three types of postural control concurrently.

description: The informational content in live cattle and hog deferred futures prices is assessed using a direct test of incremental forecast ability for two- to twelve-month horizons. For 1976-2007, the results indicate that hog futures prices add incremental information at all horizons, but unique information in live cattle prices declines quickly beyond the eight-month horizon with no incremental information at the twelve-month horizon. The contrast in performance is likely attributable to differences in the quality of public information and the nature of the production process.

description: Water-insoluble α-glucans synthesized from sucrose by glucansucrases from Streptococcus spp. are essential in dental plaque and caries formation. Because limited information is available on the fine structure of these biopolymers, we analyzed the structures of unmodified glucans produced by five recombinant Streptococcus (S.) mutans DSM 20523 and S. salivarius DSM 20560 glucansucrases in detail. A combination of methylation analysis, endo-dextranase and endo-mutanase hydrolyses, and HPSEC-RI was used. Furthermore, crystal-like regions were analyzed by using XRD and 13C MAS NMR spectroscopy. Our results showed that the glucan structures were highly diverse: Two glucans with 1,3- and 1,6-linkages were characterized in detail besides an almost exclusively 1,3-linked and a linear 1,6-linked glucan. Furthermore, one glucan contained 1,3-, 1,4-, and 1,6-linkages and thus had an unusual, not yet described structure. It was demonstrated that the glucans had a varying structural architecture by using partial enzymatic hydrolyses. Furthermore, crystal-like regions formed by 1,3-glucopyranose units were observed for the two 1,3- and 1,6-linked glucans and the linear 1,3-linked glucan. 1,6-linked regions were mobile and not involved in the crystal-like areas. Altogether, our results broaden the knowledge of the structure of water-insoluble α-glucans from Streptococcus spp.

description: We set up an original apparatus to measure the grain grain friction stress inside a granular medium composed of sodo-silicate-glass beads surrounded by a water vapor atmosphere.We analyze here the influence of the physico chemistry of water on our glass beads and its consequences on our shear experiment. We found two scales in the analysis of the shear stress signal. On the microscopic scale of one bead, the experimental results show a dependence on the size of beads, on the shear rate and on humidity for the resulting stick slip signal. On the macroscopic scale of the whole assembly of beads, the behavior of the total amplitude of the shear stress depends on the size of the beads and is humidity dependent only for relative humidity larger than 80%. For high degrees of humidity, on the microscopic scale, water lubricates the surface of the beads leading to a decrease in the microscopic resistance to shear while on the macroscopic scale the resistance to shear is increased: the assembly of very humid grains behaves as a non Newtonian fluid.

description: We calculate and resolve with unprecedented detail the local density of states (DOS) and momentum-dependent spectral functions at zero temperature of one of the key models for strongly correlated electron materials, the degenerate two-orbital Kanamori-Hubbard model, by means of a highly optimized Dynamical Mean Field Theory which uses the Density Matrix Renormalization Group as the impurity solver. When the system is hole doped, and in the presence of a finite interorbital Coulomb interaction we find the emergence of a novel holon-doublon in-gap subband which is split by the Hund's coupling. We also observe new interesting features in the DOS like the splitting of the lower Hubbard band into a coherent narrowly dispersing peak around the Fermi energy, and another subband which evolves with the chemical potential. We characterize the main transitions giving rise to each subband by calculating the response functions of specific projected operators and comparing with the energies in the atomic limit, obtaining excellent agreement. The detailed results for the spectral functions found in this work pave the way to study with great precision the microscopic quantum behavior in correlated materials.

description: Aminoalcohols were converted into the corresponding enantiomeric phenylsulfonamide sulfamates. These compounds proved to be inhibitors of carbonic anhydrase II. Interestingly, a sulfamate derived from (S)-tryptophan was no inhibitor at all while its (R) configurated enantiomer was an excellent inhibitor of carbonic anhydrase II (CA II). A rationale can be deduced from molecular modeling studies. The sulfamates derived from (R) or (S) proline held very low inhibition constants for this enzyme as Ki = 0.77 μM and 0.70 μM, respectively.

description: With the increasing demand for real-time animated 3D content in the entertainment industry and beyond, performance-based animation has garnered interest among both academic and industrial communities. While recent solutions for motion-capture animation have achieved impressive results, handmade post-processing is often needed, as the generated animations often contain artifacts. Existing real-time motion capture solutions have opted for standard signal processing methods to strengthen temporal coherence of the resulting animations and remove inaccuracies. While these methods produce smooth results, they inherently filter-out part of the dynamics of facial motion, such as high frequency transient movements. In this work, we propose a real-time animation refining system that preserves -- or even restores -- the natural dynamics of facial motions. To do so, we leverage an off-the-shelf recurrent neural network architecture that learns proper facial dynamics patterns on clean animation data. We parametrize our system using the temporal derivatives of the signal, enabling our network to process animations at any framerate. Qualitative results show that our system is able to retrieve natural motion signals from noisy or degraded input animation.

description: Local minimizers of integral functionals of the calculus of variations are analyzed under growth conditions dictated by different lower and upper bounds for the integrand. Growths of non-necessarily power type are allowed. The local boundedness of the relevant minimizers is established under a suitable balance between the lower and the upper bounds. Classical minimizers, as well as quasi-minimizers are included in our discussion. Functionals subject to so-called -growth conditions are embraced as special cases and the corresponding sharp results available in the literature are recovered.

A novel mechanism for RNase E-initiated decay of 5’-protected mRNA in Escherichia coli
Creators: name: Baker, Kristian Eileen
Publisher: name: University of British Columbia
Year: 2009

description: In Escherichia coli, 5'-terminal RNA stem-loop structures are major impediments to the rate-determining initiation of mRNA degradation catalyzed by the endonuclease RNase E. Protected RNAs do, nonetheless, decay at appreciable rates, and factors which enforce the initial barrier to decay or modulate an alternative decay pathway are unknown. A prosthetic RNA hairpin at the extreme 5'-terminus of a model mRNA substrate, r/w7mRNA, stabilized this RNA 6-fold against a decay-initiating RNase E cleavage. Altering the efficiency of translation or introducing premature-termination codons demonstrated that stem-loop-mediated stabilization of rpsT mRNA depended on efficient translational initiation and ribosome passage through the ratedetermining RNase E cleavage site within the coding sequence. Introduction of sequences encompassing characterized RNase E cleavage sites, referred to here as 'portable' RNase E cleavage sites, from either the me mRNA leader or 9S rRNA into rpsT mRNA significantly reduced the stabilizing effects of the terminal stem-loop. Destabilization by the 'portable' cleavage sequences required active RNase E, and cleavage-site mapping demonstrated endonucleolytic cleavage within the inserted sequences. Furthermore, the efficiency of destabilization by 'portable' RNase E cleavage sites was dependent on both the primary sequence of the insert as well as its position within the 5' UTR or ORF of the stem-loop-protected rpsT mRNA. This work has led to the proposal of a model for RNase E-mediated degradation of 5'- protected mRNA involving bypass of the preferred interaction with the 5' terminus and 'internal' recognition of the mRNA substrate. Moreover, the efficiency of'internal' entry appears to be determined by the intrinsic susceptibility of the rate-limiting cleavage site alone. Finally, the involvement of the arginine-rich RNA binding domain of RNase E in the internal entry mechanism of RNA degradation is discussed.

description: Recent technological advances have deepened our perception of cellular structure. However, most structural data doesn't originate from intact cells, limiting our understanding of cellular processes. Here, we discuss current and future developments that will bring us towards a structural picture of the cell. Electron cryotomography is the standard bearer, with its ability to provide in cellulo snapshots. Single-particle electron microscopy (of purified biomolecules and of complex mixtures) and covalent crosslinking combined with mass spectrometry also have significant roles to play, as do artificial intelligence algorithms in their many guises. To integrate these multiple approaches, data curation and standardisation will be critical – as is the need to expand efforts beyond our current protein-centric view to the other (macro)molecules that sustain life.

This means that supportive policies can go a long way towards providing the conditions in which people can lift themselves out of poverty. Conversely, policies that do not create opportunities, or that exclusively reflect the interests of other economic players, can be an insuperable barrier or an unbridgeable gulf – roadblocks barring the way out of the poverty trap.

description: In recent years, availability and usage of extensive systems for Electronic Healthcare Record (EHR) is increased. In medical centers such hospitals and other laboratories, more health data sets were formed during the treatment process. In order to enhance the standard of the services provided in healthcare, these records where shared and can be used by various users depends on their requirements. As a result, notable issues in the security and privacy where obtained which should be monitored and removed in order to make the use of EHR more effectively. Various researches have been done in the past literature for improving the standards of the security and privacy in E-health systems. In spite of this, it is not completely enhanced. In this paper, a comprehensive analysis is done by selecting the existing approaches and models which were proposed for the security and privacy of the E-healthcare systems. Also, a novel Intelligent-based Access Control Security Model (IBAC) based on multi agents is proposed to maintain and support the security and privacy of E-healthcare systems. This system uses agents in order to maintain security and privacy while accessing the E-health data between the users.

description: Parasitic infections in zoo animals are a critical concern for both animal health and management. The aim of this study was to assess the occurrence of endo- and ectoparasites among zoo animals in Germany. A retrospective analysis of the submitted samples of a diverse range of zoo animals (5768) from a ten-year period (2012–2022) was conducted. Overall, 31.1% of those samples tested positive for at least one parasite. In the examined samples, helminths (28.4%) were found more often than protozoans (10.3%) or ectoparasites (0.8%). Among the various animal groups the following parasites were found most commonly: Artiodactyla: Coccidia (34.6%), Strongylida (23.4%); Perissodactyla: Strongylida (19.3%), Ascaridida (12.0%); Carnivora: Ascaridida (16.6%), Coccidia (8.1%); Rodentia: Oxyurida (18.2%), Coccidia (10.5%); Marsupialia: Coccidia (9.4%), Oxyurida (5.9%); Primates: Trichuris spp. (9.7%), Oxyurida (2.2%); Aves: Capillaria (7.8%), Ascaridida (7.6%); Reptilia, Amphibia, Insecta: Oxyurida (18.7%); Pisces: Ciliates (6.2%). Furthermore, potentially zoonotic parasites were identified, including Toxoplasma gondii (0.1%), Cryptosporidium sp. (0.1%). By examining the occurrence of specific parasites, these findings demonstrate the importance of parasites in the context of zoo animal health. They also highlight the need for effective strategies to control parasite burden to improve the overall welfare of zoo animals.

description: This study analyzed the influence of demographic and behavioral characteristics on the likelihood of a consumer to read food advertisements in grocery brochures and the likelihood of a consumer to shop at more than one store to purchase advertised specials. Overall, 73% and 46% of respondents read food advertisements and shop multiple stores to purchase advertised specials, respectively. Consumer characteristics which are shown to influence the reading of food advertisements and shopping at more than one food store to buy advertised specials were the possession of education beyond the 2/4 year college degree and the tendency to read ingredient labels.

description: Introduction: Due to the increasing number of persons with dementia, the need for family and professional support is growing. Counselling services aim to support family dementia caregivers and the use of information and communication technology may improve accessibility to counselling. The effectiveness of technology-based counselling in dementia remains unclear so far. Few randomised controlled trials have been conducted assessing heterogeneous outcomes. Theoretical underpinnings for the development and evaluation of these complex interventions were lacking in most cases. We therefore aim to formulate an initial programme theory of a technology-assisted counselling intervention for family dementia caregivers and to create the data basis for the consensus process of a core outcome set. Methods and analysis: The methodological approaches for developing a programme theory and a core outcome set will be integrated. In a scoping review, data on the characteristics, theoretical foundations of counselling interventions and outcomes of clinical studies will be collected. The lifeworld perception of relevant stakeholders on the importance of counselling in family caregiving will be explored in a phenomenological substudy using semistructured interviews. The synthesis of data from the literature review and the qualitative substudy will be performed by developing a logic model. Mechanisms of action and assumed causal relationships are explicated in the elements of programme theory (theory of change, outcomes chain and theory of action). An initial programme theory is then formulated. In addition, a ‘long list’ of outcomes and assessment instruments will be compiled. Ethics and dissemination: The ethics committee of the Medical Faculty of the Martin Luther University Halle-Wittenberg approved the study protocol (no. 2023–093). Findings will be reported to participants and the funding organisation and disseminated in peer-reviewed journals and at national and international conferences.
Coherence time of a cold-atom laser below threshold

description: We experimentally study the coherence time of a below-threshold Raman laser in which the gain medium is a gas of magneto-optically trapped atoms. The second-order optical coherence exhibits photon bunching with a correlation time which is varied by two orders of magnitude by controlling the gain. Results are in good agreement with a simple analytic model which suggests the effect is dominated by gain, rather than dispersion, in this system. Cavity ring-down measurements show the photon lifetime, related to the first-order coherence time, is also increased.

description: Only 22 percent of surveyed consumers reported making frequent use of food advertisements when purchasing food products. However, certain demographic segments appear to place a greater emphasis on food advertisements than others. This study empirically evaluates which socio-economic characteristics encourage consumers to be more likely to take food advertisements into account when purchasing grocery products. The results indicate that those with lower annual incomes, those with lower levels of education, and those living in suburban and rural areas are the most likely to make use of food advertisements in the newspaper. The results also indicate that households with children, single individuals, and those over 65 years of age are less likely to use food advertisements.

description: The economics of agroterrorism has not been fully developed within the economics literature, yet with increasing concerns about agroterrorism it is important to understand how consumers will generally respond. This paper presents an overview of food safety issues, and develops an economical model that can be used to illustrate and establish hypotheses regarding consumer behavior and agroterrorism. We then present sample and econometric results from a survey of 304 New Jersey consumers and explain the characteristics of the 33% that confirmed that they have increased purchases of locally grown produce due to terrorism fears.

description: Decisions made by publicly traded agribusinesses impact suppliers, processors, farmers, and even rural communities. Professional analysts’ estimates of earnings per share (EPS) provide a unique source of information regarding firm-level financial performance. Incorporating a battery of tests, this research examines the forecast properties of consensus analysts’ EPS estimates reported in the Institutional Brokers Estimate System for a sample of publicly traded food companies. While the results are mixed among firms, they suggest 1) analysts forecasts are largely unbiased but inefficient, and may not encompass information in simple time series models, and 2) EPS may be becoming more difficult to estimate.

description: Context. Taurus represents an ideal region to study the three-dimensional distribution of the young stellar population and relate it to the associated molecular cloud. Aims. The second Gaia data release (DR2) enables us to investigate the Taurus complex in three dimensions, starting from a previously defined robust membership. The molecular cloud structured in filaments can be traced in emission using the public far-infrared maps from Herschel. Methods. From a compiled catalog of spectroscopically confirmed members, we analyze the 283 sources with reliable parallax and proper motions in the Gaia DR2 archive. We fit the distribution of parallaxes and proper motions with multiple populations described by multivariate Gaussians. We compute the cartesian Galactic coordinates (X,Y,Z) and, for the populations associated with the main cloud, also the galactic space velocity (U,V,W). We discuss the spatial distribution of the populations in relation to the structure of the filamentary molecular cloud traced by Herschel. Results. We discover the presence of six populations which are all well defined in parallax and proper motions, with the only exception being Taurus D. The derived distances range between 130 and 160 pc. We do not find a unique relation between stellar population and the associated molecular cloud: while the stellar population seems to be on the cloud surface, both lying at similar distances, this is not the case when the molecular cloud is structured in filaments. Taurus B is probably moving in the direction of Taurus A, while Taurus E appears to be moving towards them. Conclusions. The Taurus region is the result of a complex star formation history which most probably occurred in clumpy and filamentary structures that are evolving independently.
