description: In this paper, we have calculated the $α$-decay half-lives of superheavy nuclei with $106 \leq Z \leq 126$ and a neutron number of $150 \leq N \leq 200$ within proximity potentials and deformed-spherical Coulomb potentials by using $WS4$ $α$-decay energy and the semi-classical Wentzel-Kramers-Brillouin approximation for penetration probability. Besides, we have included the preformation factor within the cluster-formation model. We have investigated magic numbers and submagic numbers in the mentioned region; with high probability 162, 178, and 184 are predicted as neutron magic numbers. We also have confirmed that there is good agreement between our predicted half-lives and the ones obtained from semiempirical relationships such as Royer, VSS, UDL, and SemFIS2.

description: We present progress on the experimental validation of a fundamental and universally applicable vulnerability analysis framework that is capable of identifying new types of vulnerabilities before attackers innovate attacks. This new framework proactively identifies system components that are vulnerable based upon their Kolmogorov Complexity estimates and it facilitates prediction of previously unknown vulnerabilities that are likely to be exploited by future attack methods. A tool that utilizes a growing library of complexity estimators is presented. This work is an incremental step towards validation of the concept of complexity-based vulnerability analysis. In particular, results indicate that data types (semantic types) can be identified by estimates of their complexity. Thus, a map of complexity can identify suspicious types, such as executable data embedded within passive data types, without resorting to predefined headers, signatures, or other limiting a priori information.

description: The uncertainty relation is a fundamental limit in quantum mechanics and is of great importance to quantum information processing as it relates to quantum precision measurement. Due to interactions with the surrounding environment, a quantum system will unavoidably suffer from decoherence. Here, we investigate the dynamic behaviors of the entropic uncertainty relation of an atom-cavity interacting system under a bosonic reservoir during the crossover between Markovian and non-Markovian regimes. Specifically, we explore the dynamic behavior of the entropic uncertainty relation for a pair of incompatible observables under the reservoir-induced atomic decay effect both with and without quantum memory. We find that the uncertainty dramatically depends on both the atom-cavity and the cavity-reservoir interactions, as well as the correlation time, $τ$, of the structured reservoir. Furthermore, we verify that the uncertainty is anti-correlated with the purity of the state of the observed qubit-system. We also propose a remarkably simple and efficient way to reduce the uncertainty by utilizing quantum weak measurement reversal. Therefore our work offers a new insight into the uncertainty dynamics for multi-component measurements within an open system, and is thus important for quantum precision measurements.

description: One issue surrounding the use of Choice Modelling (CM) in policy is whether public and expert preferences diverge regarding particular environmental attributes. To investigate this issue two case studies use CM to value ecological attributes for the Ningaloo and proposed Capes marine parks in Western Australia. Public and expert populations are sampled, with consideration of information effects. Attention is also given to whether policy relevance can be improved by considering not only desired outcomes of the hypothetical policy options in the CM exercise, but also the management process used to achieve these outcomes. Preliminary results of the public sample identify significant impacts of both information and management process effects.

description: Environmental policy evaluation is characterised by a paucity of information. Bounded sets may be more appropriate for representing this ambiguity than traditional probability distributions. A formal calibration method for regional policy models, positive mathematical programming, is thus extended to incorporate parameter definition using bounded sets through the novel method of robust non-linear programming. The resulting procedure identifies strong bounds on the range of abatement costs accruing to environmental policy and improves the relevance and value of modelling studies through not limiting conclusions to realisations of specific point estimates or probability distributions. Moreover, it may easily be solved using standard mathematical-programming algorithms. Empirical insights are provided in an application to a New Zealand inland lake threatened by nitrate pollution from dairy farming. Factor substitution could potentially be used to reduce the abatement costs accruing to regulation. However, such behaviour is shown not to be optimal at the parameter values used in this study. Accordingly, large reductions in nitrate leaching and concomitant improvements in water quality potentially bear a substantial cost to producers.

description: We give a Hamiltonian analysis of the asymptotically flat spherically symmetric system of gravity coupled to a scalar field. This 1+1 dimensional field theory may be viewed as the "standard model" for studying black hole physics. Our analysis is adapted to the flat slice Painleve-Gullstrand coordinates. We give a Hamiltonian action principle for this system, which yields an asymptotic mass formula. We then perform a time gauge fixing that gives a Hamiltonian as the integral of a local density. The Hamiltonian takes a relatively simple form compared to earlier work in Schwarzschild gauge, and therefore provides a setting amenable to full quantisation.

description: (Vereenigde Oostindische Compagnie, the Dutch East India Company), one of the world’s major players in the international food market of the 17th and 18th centuries. Can the experiences of the VOC teach lessons that today’s food production networks may take to heart? There are three domains in which changes might have occurred since the times of the VOC that could be relevant to this question. These are the people themselves, the rules of the game that can be captured by the term governance, and context factors. The article will investigate all three. As far as the people are concerned it will look at factors such as worker conditions, attitudes, and culture in general. In the area of governance the paper will consider contract enforcement and coercion constraining. Context factors to consider are costs of transport and availability of capital. The method used in this article is desk research using a number of historical sources. The theories used are from NIE (New Institutional Economics) and from cultural psychology.

Approaches to assessing wage loss duration at the Workers’ Compensation Board of British Columbia
Creators: name: Walker, David Douglas
Publisher: name: University of British Columbia
Year: 2009

description: The Workers' Compensation Board of British Columbia monitors the wage loss duration of claims processed by their organization in order to assess organizational effectiveness and track a system cost driver. Multiple methods of calculating and reporting claim wage loss exist within the organization and performance results depend on which metric is used. Using existing WCB claim data, new measurements of claim duration are proposed and a comparison of wage loss metrics is conducted. The methods of wage loss measurement proposed in this study include predicted claim wage loss duration, cumulative wage loss paid to claims, claim age at closure identified using survival analysis, uncensored claim wage loss and the proportion of claims closed in the months following registration. These metrics are compared to the existing wage loss metrics which are retrospective wage loss duration and the Association of Workers' Compensation Boards of Canada complete duration. A comparison of wage loss metrics indicates that claim durations vary depending on which calculation is used. Cumulative wage loss duration is found to be higher than either of the existing metrics. Age at closure and uncensored claim duration are higher than predicted wage loss duration but lower than existing metrics. Each of the proposed metrics is capable of identifying the effect of claimant age and injury type when wage loss durations are compared across sub groups of claims. The study also indicates that in the current form, predicted wage loss duration does not accurately represent claim wage loss. The study identifies weakness in each method of computing claim wage loss and that depending on the use of the metric different measures may be appropriate. In some cases, using cumulative wage loss duration may be worthwhile to track longer claims. Uncensored claim duration and age at closure are more appropriate when comparisons of claim duration for different periods are required.

description: We apply a formal theoretical model of adaptation to two empirical settings within the agri-food industry: specialized pig production and food safety in Denmark. The objective is to allocate decision rights ex ante so that actual decisions taken ex post will optimize the profit accruing to the two parties in a contractual or integrative relation. Two applications are presented in this paper: First an actual partnership between two pork producers in Denmark. Based on detailed budgets we develop detailed schedules for the “reneging temptations” of the two partners- These are the temptations to renege on the contract during the evolution of the partnership. Using a model developed by Baker, Gibbons and Murphy (2006) we calculate equilibria using the Folk theorem in order to determine which is the best allocation of decision rights. We find that the existing allocation of decision rights in the case we examine is efficient in the sense that it results into a second best allocation. Using the same modelling approach we present a second application on salmonella control related to end-feeding, that is, salmonella contamination of pork due to filled bellies of pigs fed for the last 12 hours before delivery. Based on appropriate assumptions, the parties should give the decision right (whether to end-feed or not) to the slaughterhouse in order to reach the firstbest solution which, given the assumptions, is feasible

description: Members of the Ski/Sno protein family are classified as proto-oncogenes and act as negative regulators of the TGF-ß/BMP-pathways in vertebrates and invertebrates. A newly identified member of this protein family is fussel (fuss), the Drosophila homologue of the human functional Smad suppressing elements (fussel-15 and fussel-18). We and others have shown that Fuss interacts with SMAD4 and that overexpression leads to a strong inhibition of Dpp signaling. However, to be able to characterize the endogenous Fuss function in Drosophila melanogaster, we have generated a number of state of the art tools including anti-Fuss antibodies, specific fuss-Gal4 lines and fuss mutant fly lines via the CRISPR/Cas9 system. Fuss is a predominantly nuclear, postmitotic protein, mainly expressed in interneurons and fuss mutants are fully viable without any obvious developmental phenotype. To identify potential target genes or cells affected in fuss mutants, we conducted targeted DamID experiments in adult flies, which revealed the function of fuss in bitter gustatory neurons. We fully characterized fuss expression in the adult proboscis and by using food choice assays we were able to show that fuss mutants display defects in detecting bitter compounds. This correlated with a reduction of gustatory receptor gene expression (Gr33a, Gr66a, Gr93a) providing a molecular link to the behavioral phenotype. In addition, Fuss interacts with Rpd3, and downregulation of rpd3 in gustatory neurons phenocopies the loss of Fuss expression. Surprisingly, there is no colocalization of Fuss with phosphorylated Mad in the larval central nervous system, excluding a direct involvement of Fuss in Dpp/BMP signaling. Here we provide a first and exciting link of Fuss function in gustatory bitter neurons. Although gustatory receptors have been well characterized, little is known regarding the differentiation and maturation of gustatory neurons. This work therefore reveals Fuss as a pivotal element for the proper differentiation of bitter gustatory neurons acting within a chromatin modifying complex.

description: First, we explain some ambiguities of spacetime and metric field as fundamental concepts. Then, from the Unruh effect point of view and using the Gelfand-Naimark-Segal construction, we construct an operator as a quanta of acceleration that we call quantum acceleration operator (QAO). Thereupon, we investigate the relation between the vacuum of two different frames in the Minkowski space. Also, we show that the vacuum of each accelerated frame in the Minkowski space can be obtained by applying such a QAO to the Minkowski vacuum. Furthermore, utilizing these QAOs, we augment the Hilbert space and then extract the metric field of a general frame of the Minkowski spacetime. In this approach, these concepts emerge from the Hilbert space through the constructed QAOs. Accordingly, such an augmented Hilbert space includes quantum field theory in a general frame and can be considered as a fundamental concept instead of the classical metric field and the standard Hilbert space.

Performance analysis of a transmit diversity scheme in correlated fading with imperfect channel estimation

Publisher: name: University of British Columbia
Year: 2009

description: Exact closed-form expressions are derived for the bit error rate of Simple Transmit Diversity (STD) with 2 transmit and M receive antennas in time-selective, spatially independent Rayleigh fading with imperfect channel estimation and in non time-selective, spatially correlated Rayleigh fading with imperfect channel estimation. The performance analysis is also presented. For spatially independent fading, it is found that for the same values of the channel gain time correlation coefficient ρ[sub t] and the channel gain estimation error correlation coefficient ρ[sub e] , the error performance in non time-selective fading with imperfect channel estimation is worse than in time-selective fading with perfect channel estimation. The BER floor resulting from channel estimation errors and time-selective fading is determined. For the same values of ρ[sub t] and ρ[sub e] , say ρ, the error floor limits are approached at lower signal to noise ratio (SNR) values for (ρ[sub t] = 1, ρ[sub e] = ρ) than for (ρ[sub t] = ρ, ρ[sub e] = 1 ) . The effects of channel estimation errors on error performance of STD and Maximum Ratio Combining (MRC) were compared and it was shown that for large values of signal to noise and estimation error to noise ratios, STD suffers a 3 dB loss compared to MRC in non-time selective, spatially independent fading.

description: Supermarket shelves are saturated with numerous varieties and brands of juice beverages. This high level of assortment has dramatically changed beverage consumption patterns and trends throughout the United States. In fact, during 2004-2005, energy and sport drinks experienced significant increases in sales, 65.9% and 20.6 %, respectively. During the same period of time, refrigerated juice sales increased a mere 2.2%, shelved non-fruit drinks decreased 0.9%, bottled juices and cocktails both decreased 1.5 % and frozen juice decreased by 12.8% (Food Industry Review 2006). The beverage industry has undergone many transformations, but consumer theory states that a shift in demand for one good has to be compensated by a shift in the opposite directions in the demand for the other good. Thus, with more brands competing for consumers’ dollars, it is important for brand managers, retailers, and other industry officials to understand demand interrelationships among various beverages. This study examines the competitiveness and structure of the beverage industry. Existing research suggests the demand for fruit beverages is independent from other food and non-food groups (Heien 1982; Lee 1984); therefore, information pertaining to other goods can be omitted without compromising the validity of the study. Our study will allow us to better understand how consumers make decisions concerning purchases patterns of beverage expenditures.

description: The variety of quality systems is a very important and an actual theme in the agri-food sector. These quality systems are only partly acknowledged by different quality standard organizations, but customers within the supply chain demand them. Enterprises, which supply different customers and export abroad this, face the problem that they have to deal with several standards and implement them within the enterprise as well as take part in several systems audits and certifications. The economic problem consists of determining the most efficient introduction of a quality system or a combination of quality systems in the enterprise. The emphasis of the work lies in the development of a framework for the benchmarking of quality systems at all stages of the agri-food production and an allocation and operationalisation of cost and benefit categories. A concept including the database “QualintSys” was developed during a PhD-thesis to estimate the costs and benefits of quality systems.

As a decreases, first-passage properties approach those of continuum diffusion, but non-diffusive effects remain because of residual discreteness effects

description: The formation of tidal dwarf galaxies (TDG) inside tidal arms of interacting disk galaxies has been studied with N-body and N-body/SPH simulations at different resolutions. In pure N-body simulations no bound objects are formed at high resolution. At low resolution bound objects can form in tidal tails in agreement with previous work. We conclude that tidal dwarf galaxies are not likely to form by pure collisionless collapse in tidal tails. However, the presence of a sufficiently massive and extended gas component in the progenitor disk supports the formation of bound stellar objects in the tidal arms. Our results clearly favor a dissipation supported scenario in which the formation of TDGs is induced by the local collapse of gas which then triggers the collapse of the stellar component.

description: Convenience food is characterized by a value added to the product core that corresponds to fast changing consumer needs. Thus, convenience food can be considered as an example of one of the most innovative product categories in the domain of the food industry. Concerning innovative activities the prevailing perception of convenience food is that all decisive impulses are coming from the market e.g. are driven by the power of demand. If so, than food producers have the chance to react on these impulses when developing novel convenience food solutions timely and close to the market development intent meeting the requirements of the consumers. In this paper we are going to propose a different viewpoint: firms who are developing, producing and selling convenience food products may follow a corporate strategy which is not necessarily and primarily in line with the consumer welfare but is rather oriented to their competitors. Thus, the strategic dimension is also or predominantly geared to a firm’s competitive environment when trying to find attractive niche positions and aiming on competitive advantage by using internal resources and competencies. We understand that convenience food shows clear distinctive characteristics in comparison to conventional foods. These require a very particular set of competencies in the sense of how to employ resources and capabilities in a useful way. Additionally, we argue that the characteristics of convenience food to employ an innovation strategy based on fast processes of resource reconfiguration.

description: This paper emphasizes on the concept of innovation which is more and more nowadays recognized as of significant importance for all companies across different business sectors. The paper initially provides a review of the innovation literature in terms of types, classifications, and sources of innovation that have been proposed over time. Then, innovation in the context of the food industry is examined and it is attempted to identify innovation strategies followed by Greek food companies based on a value driven approach of innovation. The paper finally, provides insights from eight Greek food companies, which were selected from four subsectors: fruit and vegetables, dairy products, meat products (cured meats), and bakery products. The criterion used for the selection was market success and outstanding performance (e.g. market share, achieved results). Evidence indicates that companies tend to innovate along the dimension of offerings, which is more related to the traditional view of product and process innovation.

description: Many low-mass X-ray binaries show both hard and soft spectral states. For several sources the transitions between these states have been observed, mostly from the soft to the hard state during a luminosity decrease. In a few cases also the transition from the hard to the soft state was observed, coincident with an increase of the luminosity. Surprisingly this luminosity was not the same as the one during a following change back to the hard state. The values differed by a factor of about 3 to 5. We present a model for this hysteresis in the light curves of low-mass X-ray binaries (sources with neutron stars or black holes). We show that the different amount of Compton cooling or heating acting on the accretion disk corona at the time of the transition causes this switch in the accretion mode at different mass accretion rates and therefore different luminosities. The inner disk during the soft state provides a certain amount of Compton cooling which is either not present or much less if the inner region is filled with a hot advection-dominated accretion flow (ADAF) that radiates a hard spectrum.

description: We study Schreier dynamical systems associated with a vast family of groups that hosts many known examples of groups of intermediate growth. We are interested in the orbital graphs for the actions of these groups on $d-$regular rooted trees and on their boundaries, viewed as topological spaces or as spaces with measure. They form interesting families of finitely ramified graphs, and we study their combinatorics, their isomorphism classes and their geometric properties, such as growth and the number of ends.

description: The following contribution describes how an E-collaboration platform may be used within new product development. In order to develop a new dairy product (a yoghurt dessert), a leading Austrian dairy co-operated with representatives from the Austrian University of Natural Resources and Applied Live Sciences Vienna and other experts by use of a specific E-collaboration platform. The main aim of the project was the preparation of innovative product concepts. All necessary data and documents concerning consumer behaviour, market trends, product features etc. were distributed via a closed E-collaboration platform. The participants worked together for about half a year; however, only two personal meetings were necessary, all other communication processes (also group discussions) were done via the E-collaboration platform. It was possible to simultaneously communicate and co-operate even though the participants were located in Vienna, Upper Austria and Italy (South Tyrol). In the end a new product could be developed which was launched in one of the big three Austria supermarket chains in 2004. It could be proven that the state of the art in new product development is absolutely compatible with the usage of information technology for communication and knowledge transfer purposes; however, confidentiality and trust are absolutely indispensable for the success of such a project.

description: In this paper, we investigate whether current state-of-the-art large language models (LLMs) are effective as AI tutors and whether they demonstrate pedagogical abilities necessary for good AI tutoring in educational dialogues. Previous efforts towards evaluation have been limited to subjective protocols and benchmarks. To bridge this gap, we propose a unified evaluation taxonomy with eight pedagogical dimensions based on key learning sciences principles, which is designed to assess the pedagogical value of LLM-powered AI tutor responses grounded in student mistakes or confusions in the mathematical domain. We release MRBench - a new evaluation benchmark containing 192 conversations and 1,596 responses from seven state-of-the-art LLM-based and human tutors, providing gold annotations for eight pedagogical dimensions. We assess reliability of the popular Prometheus2 and Llama-3.1-8B LLMs as evaluators and analyze each tutor's pedagogical abilities, highlighting which LLMs are good tutors and which ones are more suitable as question-answering systems. We believe that the presented taxonomy, benchmark, and human-annotated labels will streamline the evaluation process and help track the progress in AI tutors' development.

description: The dependence of the Gaussian input information rate on the line-of-sight (LOS) matrix in multiple-input multiple-output coherent Rician fading channels is explored. It is proved that the outage probability and the mutual information induced by a multivariate circularly symmetric Gaussian input with any covariance matrix are monotonic in the LOS matrix D, or more precisely, monotonic in D'D in the sense of the Loewner partial order. Conversely, it is also demonstrated that this ordering on the LOS matrices is a necessary condition for the uniform monotonicity over all input covariance matrices. This result is subsequently applied to prove the monotonicity of the isotropic Gaussian input information rate and channel capacity in the singular values of the LOS matrix. Extensions to multiple-access channels are also discussed.

description: Judged by its currency, the supply chain is one of the more successful metaphors in economics. The metaphor borrows from mechanics the idea of the chain, that is something that consists of elements that are linked to each of their two immediate neighbors and which jointly provide a strong but flexible connection. The metaphor transplants the chain-idea into the sphere of economics where, before the introduction of supply chains, chains were, for most economists, things best left in the care of ironmongers. More than twenty years after its introduction the "supply chain"-metaphor appears to be losing its luster and a competition is underway in the literature where authors forge complicated arguments in support of metaphors which recognize that supply chains are not really linear chains but most often expansive networks (e.g. Lazzarini et al. 2001). For this reason the chief contenders for the pride of place seem to be neologisms such as "supply networks" or "net chains". It is not obvious to us that much will be gained by replacing chain-metaphors with network-metaphors. Few practitioners of procurement, logistics and marketing will have failed to notice that not all business arrangements are strictly chain-like and only the most unperceiving will be enlightened by the new network-metaphors. Because supply chains obviously are networks, chances are that network-metaphors will win many converts, at least for some time.
Non-Abelian gauge potentials for ultra-cold atoms with degenerate dark states

description: We show that the adiabatic motion of ultra-cold, multi-level atoms in spatially varying laser fields can give rise to effective non-Abelian gauge fields if degenerate adiabatic eigenstates of the atom-laser interaction exist. A pair of such degenerate dark states emerges e.g. if laser fields couple three internal states of an atom to a fourth common one under pairwise two--photon-resonance conditions. For this so-called tripod scheme we derive general conditions for truly non-Abelian gauge potentials and discuss special examples. In particular we show that using orthogonal laser beams with orbital angular momentum an effective magnetic field can be generated that has a monopole component.

description: Using the black string between two branes as a model of a brane-world black hole, we compute the gravity wave perturbations and identify the features arising from the additional polarizations of the graviton. The standard four-dimensional gravitational wave signal acquires late-time oscillations due to massive modes of the graviton. The Fourier transform of these oscillations shows a series of spikes associated with the masses of the Kaluza-Klein modes, providing in principle a spectroscopic signature of extra dimensions.

description: Many of the small ribosomal subunit proteins are required for the stabilisation of late small ribosomal subunit (SSU) precursors and for final SSU rRNA processing in S. cerevisiae. Among them are ribosomal proteins (r-proteins) which form a protein cluster around rpS0 (uS2) at the "neck" of the SSU (S0-cluster) and others forming a nearby protein cluster around rpS3 (uS3) at the SSU "beak". Here we applied semi-quantitative proteomics together with complementary biochemical approaches to study how incomplete assembly of these two r-protein clusters affects binding and release of SSU maturation factors and assembly of other r-proteins in late SSU precursors in S. cerevisiae. For each of the two clusters specific impairment of the local r-protein assembly state was observed in Rio2 associated SSU precursors. Besides, cluster-specific effects on the association of biogenesis factors were detected. These suggested a role of S0-cluster formation for the efficient release of the two nuclear export factors Rrp12 and Slx9 from SSU precursors and for the correct incorporation of the late acting biogenesis factor Rio2. Based on our and on previous results we propose the existence of at least two different r-protein assembly checkpoints during late SSU maturation in S. cerevisiae. We discuss in the light of recent SSU precursor structure models how r-protein assembly states might be sensed by biogenesis factors at the S0-cluster checkpoint.
