description: A relativistic Green's function approach to parity-violating quasielastic electron scattering is presented. The components of the hadron tensor are expressed in terms of the single particle Green's function, which is expanded in terms of the eigenfunctions of the non-Hermitian optical potential, in order to account for final state interactions without any loss of flux. Results for $^{12}$C, $^{16}$O, and $^{40}$Ca are presented and discussed. The effect of the strange quark contribution to the nuclear current is investigated.

description: Central bank policy suffers from time-inconsistency when facing a banking crisis: A bailout is optimal ex post but ex ante it should be limited to control moral hazard. Dollarization provides a credible commitment not to help at the cost of not helping even when it would be ex ante optimal to do so. Dollarization is good when the costs of establishing a reputation for the central bank are high, monitoring effort by the banker is important in improving returns, and when the cost of liquidating projects is moderate. However, a very severe moral hazard problem could make dollarization Undesirable. The results obtained are applied to assess the desirability of dollarization in a range of countries and the potential role of the IMF as International LOLR.

description: Strong quantum nonlocality was introduced recently as a stronger manifestation of nonlocality in multipartite systems through the notion of local irreducibility in all bipartitions. Known existence results for sets of strongly nonlocal orthogonal states are limited to product states. In this paper, based on the Rubik's cube, we give the first construction of such sets consisting of entangled states in $d\otimes d\otimes d$ for all $d\geq 3$. Consequently, we answer an open problem given by Halder \emph{et al.} [Phys. Rev. Lett. \textbf{122}, 040403 (2019)], that is, orthogonal entangled bases that are strongly nonlocal do exist. Furthermore, we propose two entanglement-assisted protocols for local discrimination of our results. Each protocol consumes less entanglement resource than the teleportation-based protocol averagely. Our results exhibit the phenomenon of strong quantum nonlocality with entanglement.

description: A basic result of new economic geography (NEG) models is that the proximity to consumer markets impacts wages and employment within regions. The ongoing process of European integration, being targeted on the reduction of barriers to trade and factor mobility, has presumably changed relative market access in Europe. The present paper aims at providing some evidence on spatial effects of integration released by declining border impediments and changing market potentials. The analysis departs from a three-region economic geography model. We focus on the impact of integration on European border regions and the question whether they realise above average integration benefits. The empirical analysis concerns integration effects in the EU15 regions arising from a reduction of non-tariff and other barriers since the mid 1970s.

description: The issue of whether or not to label will be a crucial one for the U.S. agricultural sector in the coming years. This paper develops a discussion of biotechnology in agriculture in the U.S., reports on the results of a survey to examine consumer response to labeling genetically modified foods, and discusses policy implications for markets and trade in genetically modified foods. Two hundred and fifty responses to a 2003 mail questionnaire survey were analyzed for the paper. Chi-square test of independence was applied to data. Analyses showed that only 4.6% of consumers agreed that labeling should not be required for any biotech foods, while 94.4% agreed with the statement that labeling should be required for some or all biotech foods sold in the U.S. At p q 0.001, chi-square tests showed that preferences for the labeling scenarios posed were dependent on gender, number of people in household, race, religious preference, age, education, place of residence, and income. Results can be used in providing guidance for labeling policy.

description: Quantum superpositions and entanglement are at the heart of the quantum information science. There have been only a few investigations of these phenomena at the mesoscopic level, despite the fact that these systems are promising for quantum state storage and processing. Here we present two novel experiments with surface plasmons propagating on cm-long metallic stripe waveguides. We demonstrate that two plasmons can be entangled at remote places. In addition, we create a single plasmon in a temporal superposition state: it exists in a superposition of two widely separated moments. These quantum states, created using photons at telecom wavelength, are collectively held by a mesoscopic number of electrons coding a single quantum bit of information; They are shown to be very robust against decoherence.

description: This case study focuses on meat goat marketing involving one distinct immigrant group residing in one area of Columbus, Ohio: the Somalis. There are about 20,000-25,000 Somalis living in Columbus, the second largest concentration of Somalian immigrants in the U.S. after Minneapolis-St. Paul, Minnesota. It is estimated that Columbus Somalis consume the meat from about 14,000 goats each year. The objective of this pilot study is to analyze the meat goat marketing and consumption patterns of the Somali immigrant population of Columbus, Ohio. Understanding gained in the Somali meat market will assist in determining the feasibility of establishing a more structured marketing system, including the possible need for a processing plant dedicated to goat meat. The Southern Ohio Meat Goat Task Force is a group of meat-goat producers, marketers, OSU extension professionals, and Ohio Cooperative Development Center staff members that are working with the meat-goat industry to assess and develop goat production, processing, and meat marketing in Ohio. Tours of several retail shops within the Somali community were conducted to further understand the preferences of the Somali population. Interviews were conducted with a slaughter-plant manager in nearby Detroit, Michigan, the current major supplier of fresh goat meat to the Columbus market. During January and March 2003, two focus-group sessions were organized and conducted by task force members with Somali consumers, entrepreneurs, and retail grocery owners. Significant results and discussion presented in detail within this research report include: Somalia's prefer fresh over frozen goat meat, pricing is a key determinant in meat choices for Somali consumers, goat meat and lamb meat are somewhat substitutable in Somali diets, Somalis will substitute halal chicken and beef if lamb and goat meat is not available, lean grass-fed carcass is preferred to a grain-fed goat, Somalis eat goat meat 1-2 times a day year-round, most people feeding families buy a whole carcass, and only a slight preference was indicated between the halal and kosher slaughter practices.

description: This research report provides an examination of the ratings of an important sensory attribute of chevon (goat meat) with that of beef and pork. Results from an analysis of variance of comparative ratings of the flavor of chevon and that of beef and pork suggest that selected demographic characteristics of U.S. consumers influenced the ratings of chevon's flavor with that of beef and pork. The findings indicate that Hispanics, blacks, and females should not be treated as homogenous niche markets. The results suggest that there are distinct subdivision preferences within and between these consumer partitions.

description: We introduce a new criterion which tests if a given decomposition of a given ternary form $T$ of even degree is unique. The criterion is based on the analysis of the Hilbert function of the projective set of points $Z$ associated to the decomposition, and on the Terracini's Lemma which describes tangent spaces to secant varieties. The criterion works in a range for the length of the decomposition which is equivalent to the range in which the reshaped Kruskal's criterion (see [1]) works. Our criterion determines an algorithm for the identifiability of $T$ which is sensibly faster than algorithms based on the reshaped Kruskal's criterion, especially when the set of points $Z$ is not in general position.

description: In this paper I focus on some important biological aspects of the forest management problem. I model a stochastically developing forest as a multidimensional, continuous-time Markov chain. Next, I pose three questions concerning the long-run characteristics of a stationary forest, the stochastic process followed by dying species, and the age of an arbitrary species in the forest. I then (a) characterize a stationary forest probabilistically, (b) describe the stochastic process governing the demise of species in this forest, and (c) provide a method for determining the age of an arbitrary species in the forest. Finally, I discuss the forest management implications of the issues raised in this paper. Note: Published in Ecological Modelling 89(1-3, 1996):67-72.

description: In this paper we study some aspects of the question of international environmental regulation from a game theoretic perspective. We address two broad questions. First, we examine the circumstances under which the pursuit of unilateral environmental policy by a country in a Stackelberg game will make that country worse off. Second, we study the effects of environmental regulation by means of alternate price control instruments in a Stackelberg game where there is transboundary pollution. We find that there are plausible theoretical circumstances in which the pursuit of unilateral environmental policy is not a good idea. Further, we show that in choosing between alternate pollution control instruments, national governments typically face a tradeoff between instruments which correct more distortions but are costly to implement and instruments which correct fewer distortions but are less costly to implement. In particular, we obtain a dominance result for a tariff policy; this result favors the use of tariffs from an informational standpoint alone.

Vulnerable to possibilities : a journey of self-knowing through personal narrative

description: This study examines one man's experience of becoming an adult educator. Pausing to reflect after twenty-six years of teaching others how to teach, I set out to excavate the foundations of my professional practice, to crack open such questions as How did I become this teacher? and How does my lived experience inform my professional practice? Zooming between the personal and the professional, I layer autobiographical memories, critical incidents, narrative poetry, photographs, collages, and fictional dialogues into a multi-voiced narrative. Declining the security of traditional research tools (such as testing, measuring, classifying, generalizing, and theorizing), I turn instead to the Zen notion of Beginner's Mind, an approach that opens me to many possibilities. Rummaging amongst the messy fragments of lived experience, I encounter the slipperiness of language and the subjectivity of interpretation. I roam widely in the literature and invite colleagues to read and respond to work-in-progress. In due course I find that whole-hearted writing fosters self-transformation and that exposing such work to others triggers conversations about identity and integrity. I now present an open text—one that invites readers to locate their own stories between the lines, interrogate their own teacher persona, and awaken to their own experience
A Mechanical Screwing Tool for 2-Finger Parallel Grippers -- Design, Optimization, and Manipulation Policies

description: This paper develops a mechanical tool as well as its manipulation policies for 2-finger parallel robotic grippers. It primarily focuses on a mechanism that converts the gripping motion of 2-finger parallel grippers into a continuous rotation to realize tasks like fastening screws. The essential structure of the tool comprises a Scissor-Like Element (SLE) mechanism and a double-ratchet mechanism. They together convert repeated linear motion into continuous rotating motion. At the joints of the SLE mechanism, elastic elements are attached to provide resisting force for holding the tool as well as for producing torque output when a gripper releases the tool. The tool is entirely mechanical, allowing robots to use the tool without any peripherals and power supply. The paper presents the details of the tool design, optimizes its dimensions and effective stroke lengths, and studies the contacts and forces to achieve stable grasping and screwing. Besides the design, the paper develops manipulation policies for the tool. The policies include visual recognition, picking-up and manipulation, and exchanging tooltips. The developed tool produces clockwise rotation at the front end and counter-clockwise rotation at the back end. Various tooltips can be installed at both two ends. Robots may employ the developed manipulation policies to exchange the tooltips and rotating directions following the needs of specific fastening or loosening tasks. Robots can also reorient the tool using pick-and-place or handover, and move the tool to work poses using the policies. The designed tool, together with the developed manipulation policies, are analyzed and verified in several real-world applications. The tool is small, cordless, convenient, and has good robustness and adaptability.

description: Objective: The aim of this paper is to survey the recent work in medical documents summarization. Background: During the last decade, documents summarization got increasing attention by the AI research community. More recently it also attracted the interest of the medical research community as well, due to the enormous growth of information that is available to the physicians and researchers in medicine, through the large and growing number of published journals, conference proceedings, medical sites and portals on the World Wide Web, electronic medical records, etc. Methodology: This survey gives first a general background on documents summarization, presenting the factors that summarization depends upon, discussing evaluation issues and describing briefly the various types of summarization techniques. It then examines the characteristics of the medical domain through the different types of medical documents. Finally, it presents and discusses the summarization techniques used so far in the medical domain, referring to the corresponding systems and their characteristics. Discussion and conclusions: The paper discusses thoroughly the promising paths for future research in medical documents summarization. It mainly focuses on the issue of scaling to large collections of documents in various languages and from different media, on personalization issues, on portability to new sub-domains, and on the integration of summarization technology in practical applications

description: Whether and to what extent animals experience emotions is crucial for understanding their decisions and behaviour, and underpins a range of scientific fields, including animal behaviour, neuroscience, evolutionary biology and animal welfare science. However, research has predominantly focused on alleviating negative emotions in animals, with the expression of positive emotions left largely unexplored. Therefore, little is known about positive emotions in animals and how their expression is mediated. We used tail handling to induce a negative mood in laboratory mice and found that while being more anxious and depressed increased their expression of a discrete negative emotion (disappointment), meaning that they were less resilient to negative events, their capacity to express a discrete positive emotion (elation) was unaffected relative to control mice. Therefore, we show not only that mice have discrete positive emotions, but that they do so regardless of their current mood state. Our findings are the first to suggest that the expression of discrete positive and negative emotions in animals is not equally affected by long-term mood state. Our results also demonstrate that repeated negative events can have a cumulative effect to reduce resilience in laboratory animals, which has significant implications for animal welfare.

description: TIMMI2 diffraction-limited mid-infrared images of a multipolar proto-planetary nebula IRAS 16594-4656 and a young [WC] elliptical planetary nebula IRAS 07027-7934 are presented. Their dust shells are for the first time resolved (only marginally in the case of IRAS 07027-7934) by applying the Lucy-Richardson deconvolution algorithm to the data, taken under exceptionally good seeing conditions (<0.5"). IRAS 16594-4656 exhibits a two-peaked morphology at 8.6, 11.5 and 11.7 microns which is mainly attributed to emission from PAHs. Our observations suggest that the central star is surrounded by a toroidal structure observed edge-on with a radius of 0.4" (~640 AU at an assumed distance of 1.6 kpc) with its polar axis at P.A.~80 degrees, coincident with the orientation defined by only one of the bipolar outflows identified in the HST optical images. We suggest that the material expelled from the central source is currently being collimated in this direction and that the multiple outflow formation has not been coeval. IRAS 07027-7934 shows a bright, marginally extended emission (FWHM=0.3") in the mid-infrared with a slightly elongated shape along the N-S direction, consistent with the morphology detected by HST in the near-infrared. The mid-infrared emission is interpreted as the result of the combined contribution of small, highly ionized PAHs and relatively hot dust continuum. We propose that IRAS 07027-7934 may have recently experienced a thermal pulse (likely at the end of the AGB) which has produced a radical change in the chemistry of its central star.

description: Recently we have studied, using a boundary-value approach, quantum amplitudes resulting from gravitational collapse to a black hole. Suitable boundary data for all fields present are posed on initial and final space-like asymptotically flat hypersurfaces $Σ_{I,F}$. The Lorentzian proper-time separation between the surfaces, as measured at spatial infinity, is denoted by $T$. Following Feynman's $+iε$ approach, we rotate $T$ into the complex: $T\to {\mid}T{\mid} \exp(-iθ)$, where $0 0$. The Lorentzian amplitude is found by taking the limit $θ\to 0_+$ of the quantum amplitude, itself closely approximated by the semi-classical expression $\exp(iS_{\rm class})$, where $S_{\rm class}$ is the classical action. For given weak anisotropic spin-0 and spin-2 boundary data on $Σ_F$, one can compute an effective classical energy-momentum tensor in the interior, which has been averaged over several wave-lengths of the radiation. This averaged extra contribution will be spherically symmetric, equivalent to a null fluid, and describing the radial outward streaming of the radiation (of quantum origin). The corresponding space-time metric, in this region containing radially-outgoing radiation, is of the Vaidya form. This, in turn, justifies the treatment of the adiabatic radial mode equations, for spins $s=0$ and $s=2$, which is used throughout this larger project.

description: Owing to their high surface area, their high stability, and their hydrophobicity, periodic mesoporous organosilica (PMO) materials represent promising catalytic support for environmentally friendly chemical processes in water. We investigate here how the calcination of PMO material with benzene linkers (PMOB) allows its functionalization. Conventional and dynamic nuclear polarization (DNP)-enhanced NMR spectroscopy, diffuse reflectance infrared Fourier transform spectroscopy, and X-ray photoelectron spectroscopy prove that calcination at 450 °C results in the oxidation of phenylene bridges into (poly)phenols but also into carboxylic acids. Ketone, aldehyde, as well as allyl and aliphatic alcohol functionalities are also observed, but their amount is much lower than that of carboxylic acids. The calcination also cleaves the Si-C bonds. Nevertheless, N2 adsorption desorption measurements, powder X-ray diffraction, and transmission electron microscopy indicate that the PMOB materials calcined up to 600 °C still exhibit ordered mesopores. We show that the phenol and carboxylic acid functionalities of PMOB calcined at 450 °C protonate the NH2 group of 1-(3-aminopropyl)imidazole (API) in water at room temperature, but no formation of a covalent bond between API and the calcined PMOB functionalities has been detected.

description: The population of the Ounein Valley in the High Atlas Mountains in Morocco is at high risk of iodine deficiency. We investigated local children's iodine deficiency and goiter patterns as well as food consumption habits through a household survey. Median urinary iodine content and goiter analysis both reflect moderate iodine deficiency. Total fish consumption has a statistically significant, positive effect on urinary iodine content. Fish consumption, like that of salt, is closely related to market access. Respondents are uniformly unaware of the dietary etiology of goiter. An effective strategy to reduce the high incidence of iodine deficiency disorder among children in the valley must attend to four crucial issues: fish consumption, salt iodization, nutrition education, and market access.

description: All experiments observing showers light use telescopes equipped with pixellised photodetectors. Monte-Carlo (MC) simulations of the apparatus operation in various situations (background light, shower energy, proximity of tracks...) are mandatory, but never enter into detector details like pulse shape, dead-time, or charge space effects which are finally responsible for the data quality. An apparatus where each pixel receives light from individual 370 nm UV LEDs through silica fibers is being built. The LEDs receive voltage through DACs, which get their input (which pixel, at what time, which amplitude) from a shower plus noise generator code. The typical time constant of a shower being one $/mu$s (300 m for light), the pulses are one $/mu$s wide. This is rather long compared to the intrinsic time constant (around 10 ns) of the light detectors, hence, these see "constant light" changing every $/mu$s. This is where important loading effects which are not included in MC code can be observed. The fibers illuminate the pixels through a diffuser, and each fiber illuminates only one pixel. The number of equipped pixels is such that it englobes a full shower (much less than the full focal surface). Finally, this equipment can be used also to calibrate the pixels.

description: Various aspects of distillation of noisy entanglement and some associated effects in quantum error correction are considered. In particular we prove that if only one--way classical communication (from Alice to Bob) is allowed and the shared $d \otimes d$ state is not pure then there is a threshold for optimal entanglement fraction $F$ of the state (being an overlap between the shared state and symmetric maximally entangled state) which can be obtained in single copy distillation process. This implies that to get (probabilistically) arbitrary good conclusive teleportation via mixed state at least one classical bit of backward communication (for Bob to Alice) has to be sent. We provide several other threshold properties in this context including in particular the existence of ultimate threshold of optimal $F$ for states of full rank. Finally the threshold results are linked to those of error correction. Namely it is pointed out that in quantum computer working on fixed number of quantum bits almost any kind of noise can be (probabilistically) corrected only to some threshold error bar though there are some (rare) exceptions.

description: This paper presents the measurement of the scattering of 172 MeV/c muons in assorted materials, including liquid hydrogen, motivated by the need to understand ionisation cooling for muon acceleration. Data are compared with predictions from the Geant 4 simulation code and this simulation is used to deconvolute detector effects. The scattering distributions obtained are compared with the Moliere theory of multiple scattering and, in the case of liquid hydrogen, with ELMS. With the exception of ELMS, none of the models are found to provide a good description of the data. The results suggest that ionisation cooling will work better than would be predicted by Geant 4.7.0p01.

description: We propose a supersymmetric SU(5)xSU(5) model, where the quarks and leptons live in a U(1) product group theory space that is compactified on the real projective plane RP^2. The fermion generations are placed on different points in the deconstructed manifold by assigning them SO(10) compatible U(1) charges. The observed masses and mixing angles of quarks and leptons emerge from non-renormalizable operators involving the chiral link fields. The link fields introduce a large atmospheric neutrino mixing angle θ_23 via a dynamical realization of the seesaw mechanism, which sets the deconstruction scale to a value of the order the B-L breaking scale 10^14 GeV. Supersymmetry breaking can be achieved through topological effects due to a non-trivial homology group Z_2. The mixed anomalies of the link fields are canceled by Wess-Zumino terms, which are local polynomials in the gauge and link fields only. We also comment on the construction of Chern-Simons couplings from these fields.

description: Active Learning is concerned with the question of how to identify the most useful samples for a Machine Learning algorithm to be trained with. When applied correctly, it can be a very powerful tool to counteract the immense data requirements of Artificial Neural Networks. However, we find that it is often applied with not enough care and domain knowledge. As a consequence, unrealistic hopes are raised and transfer of the experimental results from one dataset to another becomes unnecessarily hard. In this work we analyse the robustness of different Active Learning methods with respect to classifier capacity, exchangeability and type, as well as hyperparameters and falsely labelled data. Experiments reveal possible biases towards the architecture used for sample selection, resulting in suboptimal performance for other classifiers. We further propose the new "Sum of Squared Logits" method based on the Simpson diversity index and investigate the effect of using the confusion matrix for balancing in sample selection.

Specific interactions between carbohydrate-binding modules and cellulose
Creators: name: McLean, Bradley William
Publisher: name: University of British Columbia
Year: 2009

description: Polysaccharidases and the carbohydrate-binding modules (CBMs) have evolved to mirror the diversity inherent in the crystalline and amorphous structures of cellulose and other polysaccharides abundant in nature. In this study, the binding specificities for cellulose of CBMs representing each of the three functional types of CBMs (types A, B and C), were determined by a series of pair-wise competition binding experiments. These studies show that different binding sites of phosphoric acid-swollen cellulose (PASC) are bound by different CBMs: type A localize to crystalline regions, type B localize to the amorphous regions. The data suggest that there is heterogeneity in the amorphous regions of PASC. The binding of the family 2a CBM from Cellulomonas fimi xylanase 10A (CBM2a) to insoluble cellulose was characterized in more detail. Competition experiments indicate that CBM2a binds to the crystalline regions of cellulose. It has been reported that CBM2a binds irreversibly to cellulose however, it is shown here that CBM2a bound to the cellulose surface can be displaced by CBM2a in solution. CBM2a has a number of conserved residues on the binding face, including three tryptophans that have been implicated in the binding reaction. Site-directed mutation and a Langmuir-type adsorption isotherm analysis was used to determine the individual contributions of W17, W54, W72 and a number of neighbouring residues to the overall binding affinity of CBM2a for cellulose. Each tryptophan plays a different role in binding; a tryptophan is essential at position 54, a tyrosine or tryptophan at position 17 and any aromatic residue at position 72. Other residues on the binding face, with the exception of N15, are not essential determinants of binding affinity. In an attempt to formulate a structural model of CBM2a bound to the surface of cellulose, observation of ¹⁵N-labelled CBM2a bound to ¹³C-enriched cellulose using solid state NMR was attempted. Given the specificity of CBM2a, the structure of crystalline cellulose and the dynamic nature of the binding of CBM2a, a model is proposed for the interaction between the polypeptide and the crystalline surface that is also likely to apply to other type A CBMs.

description: We study the gravitational collapse in five-dimensional de Sitter (dS) spacetime and discuss the existence of the conformal boundaries at future timelike infinity from the perspective of the dS/CFT correspondence. We investigate the motion of a spherical dust shell and the black hole area bounds. The latter includes the analysis of the trapping horizon and the initial data with spindle-shaped matter distribution. In all above analyses we find the evidences that guarantee the existence of the conformal boundaries at future timelike infinity which are essential to apply the dS/CFT correspondence.

description: The problem of scheduling input applications can be examined by extending conventional production function analysis. Using appropriately designed agricultural experiments, it is possible to estimate production function parameters with alternative specifications for input timing (and amount). A study of nitrogen applications to rice is employed to illustrate scheduling via production functions. Alternative specifications and functional forms are simultaneously examined to determine the sensitivity of economic results to these factors. Sensitivity is found to be high, and this finding is hypothesized to be critical for other approaches to input scheduling as well.

description: We shortly recall the mathematical and physical aspects of Talbot's self-imaging effect occurring in near-field diffraction. In the rational paraxial approximation, the Talbot images are formed at distances z=p/q, where p and q are coprimes, and are superpositions of q equally spaced images of the original binary transmission (Ronchi) grating. This interpretation offers the possibility to express the Talbot effect through Gauss sums. Here, we pay attention to the Talbot effect in the case of dispersion in optical fibers presenting our considerations based on the close relationships of the mathematical representations of diffraction and dispersion. Although dispersion deals with continuous functions, such as gaussian and supergaussian pulses, whereas in diffraction one frequently deals with discontinuous functions, the mathematical correspondence enables one to characterize the Talbot effect in the two cases with minor differences. In addition, we apply, for the first time to our knowledge, the wavelet transform to the fractal Talbot effect in both diffraction and fiber dispersion. In the first case, the self similar character of the transverse paraxial field at irrational multiples of the Talbot distance is confirmed, whereas in the second case it is shown that the field is not self similar for supergaussian pulses. Finally, a high-precision measurement of irrational distances employing the fractal index determined with the wavelet transform is pointed out
