description: Epithelial cells form barriers that coat and protect organs and organisms from their environments. Epithelial tissue function requires both adherens junctions to adhere cells together and tight junctions to create a selectively permeable barrier between neighboring cells. Sites of high tension along cell-cell contacts are called tricellular junctions, the points where three cells meet. Junctional integrity must be maintained when epithelia are challenged by mechanical stress, such as food passing through the intestines to mechanical stress through increasing connections to an actomyosin (F-actin and Myosin II) array. Here, we aimed to characterize how Vinculin, actomyosin, and junctional proteins are reorganized at tricellular junctions after either Vinculin knockdown and/or the tension-increasing treatments. We began by quantifying changes in fluorescence intensity of mNeon-Vinculin and Halo-Vinculin at tricellular junctions after increasing tension in the epithelia. After ATP treatment or the optogenetic activation of RhoA, we found that Vinculin intensity is enriched at tricellular junctions and reorganizes from distinct “spots” into elongated “spokes” along the junction. To understand Vinculin’s effects in maintaining actomyosin, we performed immunofluorescence staining for F-actin and Myosin II light chain in control and Vinculin knockdown epithelia. We found that there are reduced levels of actomyosin and disrupted actomyosin organization at tricellular junctions when Vinculin is knocked down. Next, we aimed to investigate whether Vinculin supports tricellular junction integrity. To test this, we performed immunofluorescence imaging of the adherens junction protein E-cadherin and the tricellular tight junction protein Angulin-1 after Vinculin knockdown. These experiments show that Vinculin knockdown decreases E-cadherin and Angulin-1 intensity at tricellular junctions, suggesting that Vinculin plays a role in maintaining tricellular adherens and tight junctions. Finally, to explore Vinculin’s role in barrier function, we performed a barrier assay, ZnUMBA, to measure leaks in the space between cells. With this assay, we found a greater percentage of leaky tricellular tight junctions under Vinculin knockdown conditions. Taken together, these data suggest that the mechanosensitive recruitment of Vinculin to tricellular adherens or the bladder expanding. Vinculin, a mechanosensitive protein, strengthens adherens junctions in response junctions under increased tension is essential for proper actomyosin organization and maintaining junctional integrity.

description: The field of combinatorial chemistry is highly interested in determining the structure of polyketide synthases (PKS) to manipulate existing PKS systems into producing macrolide antibiotics. To do so, we utilized x-ray crystallography, a method of structure determination that has been widely used across biological systems. Here, we determine the structure of the dehydratase (DH) domain within module 5 from the juvenimicin modular polyketide synthase pathway and confirm the presence of a DH:DH dimerization interface in the excised protein. Structure determination was achieved using molecular replacement with the PHENIX software suite. Our results provide insight into the molecular mechanism of PKS biosynthesis and may be useful in the development of novel drugs. Furthermore, our study demonstrates the utility of x-ray crystallography in the study of PKSs and highlights the importance of studying the structure and function of individual PKS domains.

description: The effects of alternative beef import policies on price and output responses in the beef and pork sectors of the livestock-meat economy are analyzed for the period 1971-80. A base model, representing the current meat import regulation, was used to project the behavior of these sectors through 1980. Then the base model was modified to simulate alternative import policies and the results were compared with the base projection values. A restrictive import policy which reduced beef imports to zero by 1975 resulted in a smaller supply of meat at somewhat higher hog and steer prices. A liberalized import policy allowing beef imports to double in the 1970's resulted in greater beef supplies at lower prices for Choice steers and hogs. An increased supply of lower grade beef became available to consumers as the supply of fed beef declined. A quarterly quota, somewhat more restrictive than current regulations, stabilized beef imports at slightly lower levels than the current policy and resulted in further growth of the domestic beef industry compared with the base projection values. A policy to stabilize the supply of nonfed beef at 36-40 pounds per person per year showed a lower rate of growth in the domestic cattle industry. A policy to stabilize Choice steer prices through controls of beef imports achieved a gradual upward trend in steer prices with some seasonal variations, no significant effect on hog prices, and limited growth of the domestic cattle industry.

description: The supplier selection problem is based on electing the best supplier from a group of pre-specified candidates, is identified as a Multi Criteria Decision Making (MCDM), is proportionately significant in terms of qualitative and quantitative attributes. It is a fundamental issue to achieve a trade-off between such quantifiable and unquantifiable attributes with an aim to accomplish the best solution to the abovementioned problem. This article portrays a metaheuristic based optimization model to solve this NP-Complete problem. Initially the Analytic Hierarchy Process (AHP) is implemented to generate an initial feasible solution of the problem. Thereafter a Simulated Annealing (SA) algorithm is exploited to improve the quality of the obtained solution. The Taguchi robust design method is exploited to solve the critical issues on the subject of the parameter selection of the SA technique. In order to verify the proposed methodology the numerical results are demonstrated based on tangible industry data.

description: The survey propagation (SP) algorithm has been shown to work well on large instances of the random 3-SAT problem near its phase transition. It was shown that SP estimates marginals over covers that represent clusters of solutions. The SP-y algorithm generalizes SP to work on the maximum satisfiability (Max-SAT) problem, but the cover interpretation of SP does not generalize to SP-y. In this paper, we formulate the relaxed survey propagation (RSP) algorithm, which extends the SP algorithm to apply to the weighted Max-SAT problem. We show that RSP has an interpretation of estimating marginals over covers violating a set of clauses with minimal weight. This naturally generalizes the cover interpretation of SP. Empirically, we show that RSP outperforms SP-y and other state-of-the-art Max-SAT solvers on random Max-SAT instances. RSP also outperforms state-of-the-art weighted Max-SAT solvers on random weighted Max-SAT instances.

This result has wide implications in the search for astrophysically viable alternatives to black holes, but also in the understanding of black holes and Hawking evaporation. Here we investigate this instability in detail for a particular setup which can be realized in the laboratory: the {\it hydrodynamic vortex}, an effective geometry for sound waves, with ergoregion and without an event horizon.

description: We report on numerical simulations of the intrinsic spin Hall effect in semiconductor quantum wires as a function of the Rashba spin-orbit coupling strength, the electron density, and the width of the wire. We find that the strength of the spin Hall effect does not depend monotonically on these parameters, but instead exhibits a local maximum. This behavior is explained by considering the dispersion relation of the electrons in the wire, which is characterized by the anticrossing of adjacent subbands. These results lead to a simple estimate of the optimal wire width for spin Hall transport experiments, and simulations indicate that this optimal width is independent of disorder. The anticrossing of adjacent subbands is related to a quantum phase transition in momentum space, and is accompanied by an enhancement of the Berry curvature and subsequently in the magnitude of the spin Hall effect.

description: Environmental cues serve as predictors of biologically relevant rewards by associative learning. However, these cues can become also imbued with incentive value, which can gain excessive and maladaptive control of behavior. Such attribution of incentive value can parallel many psychopathologies including substance use disorders and externalizing disorders. We use a Pavlovian conditioned approach (PavCA) training paradigm in which the presentation of a lever cue (conditioned stimulus, CS) directly precedes delivery of a food reward (unconditioned stimulus, US). Some rats (sign-trackers) will develop a conditioned response towards the lever- CS when it is presented and will attribute it with incentive and predictive value (i.e., sign-trackers, STs). On the other hand, another subset of animals will instead approach the food magazine when the lever-CS is presented, seeing the lever-CS only as a predictor of reward (i.e., goal-trackers). We know that STs show more engagement of “bottom-up” circuitry than GTs, with the pathway from the lateral hypothalamus (LH) to the paraventricular nucleus of the thalamus (PVT) being a major subcortical pathway underlying this behavior. We also know that STs show more activity in the LH in response to cue presentation, lesions of the LH attenuate sign-tracking behavior, and that antagonism of receptors of orexin (OX), a neuropeptide largely expressed in the LH, appears to attenuate sign-tracking. Here, we characterize the neuronal projections from the LH to the PVT using a novel combination of techniques: hairpin chain reaction in-situ hybridization (HCR FISH) and immunofluorescence (IF). We confirm that STs show more engagement of the LH, and of the LH-PVT pathway, and we discover that they also show more activity in the OXergic LH-PVT projections relative to GTs. We also compare subregions of the LH and find that the posterior LH appears to send more OXergic projections to the PVT than the anterior LH. Future studies should confirm the unique activities of OXergic projections in STs relative to GTs, which could be achieved through pathway manipulations (ex. chemogenetics and optogenetics) to OXergic transmission. Further, it is important to continue indexing rostrocaudal differences in the LH.

description: Practically all programming languages allow the programmer to split a program into several modules which brings along several advantages in software development. In this paper, we are interested in the area of answer-set programming where fully declarative and nonmonotonic languages are applied. In this context, obtaining a modular structure for programs is by no means straightforward since the output of an entire program cannot in general be composed from the output of its components. To better understand the effects of disjunctive information on modularity we restrict the scope of analysis to the case of disjunctive logic programs (DLPs) subject to stable-model semantics. We define the notion of a DLP-function, where a well-defined input/output interface is provided, and establish a novel module theorem which indicates the compositionality of stable-model semantics for DLP-functions. The module theorem extends the well-known splitting-set theorem and enables the decomposition of DLP-functions given their strongly connected components based on positive dependencies induced by rules. In this setting, it is also possible to split shared disjunctive rules among components using a generalized shifting technique. The concept of modular equivalence is introduced for the mutual comparison of DLP-functions using a generalization of a translation-based verification method.

description: Genomes of all organisms are full of genes that duplicated and then subsequently diversified in function during evolution. A primary goal of evolutionary genetics is to mechanistically understand how genes evolve following duplication such that both copies become essential and retained by evolution across millions of years of evolutionary time. In my research, I used the evolution and diversification of the three TDH genes within Saccharomyces cerevisiae, to investigate this question. The TDH gene duplicates (TDH1, TDH2, TDH3) are involved in the fundamental process of glycolysis, through which sugars are converted to energy, and specifically catalyze the conversion of glyceraldehyde-3-phosphate in this pathway. My research asks explicitly if the three TDH genes have diverged with respect to their effects on growth rate and whether this divergence happened through changes in the gene promoter or the protein-coding region. I first measured the effect of each TDH gene on growth rate by using CRISPR-Cas9 to delete them individually and in combination. I then determined whether the divergence between genes was because of changes in the gene promoters or the protein-coding sequences by swapping the promoters and protein-coding sequences between the TDH genes and measuring growth rate. My data shows that the TDH duplicates have diverged in some functions but retained other conserved functions. Further, my data shows that most functional differentiation between the TDH genes, with respect to effects on growth rate, occurred through changes in the promoter that alters gene expression. However, I also discovered that the TDH paralogs may have roles beyond glycolysis and fermentative growth. To investigate this, fluorescent microscopy was used to determine if the subfunctionalization of TDH regulatory sequences over evolutionary time was followed by the neofunctionalization of protein-coding sequences.

description: Mental conditions both resembling and having the name of hysteria have existed in some form since around 4000 B.C. It presented mainly as symptoms commonly associated today with hysteria, although the cause was thought to be uterine movement. Starting in the modern period, hysteria became a diagnosis that was more heavily associated with mental health. There is, however, a gap in the lengthy history of hysteria during the 14th and 15th centuries. Throughout various European, mostly Iberian, medical texts, there is limited evidence of a specific female mental state, with pregnancy and childbirth making up most medieval medical discourse surrounding women. Despite this lack of medical discourse surrounding women in medieval Iberian medical literature, there is discussion of women and their capacity to cause illness. This thesis argues that the discourse surrounding women in 15th century Iberian popular culture allowed for the reappearance of hysteria as a medical diagnosis and social phenomenon.

Searches for pairs of Higgs bosons, in the bbtt?, bbbb, bbgg, and multilepton final states, are included in this combination. The combination results prove to show a higher sensitivity compared with individual channels, as predicted by the Standard Model (SM). A beyond the Standard Model (BSM) interpretation, called the hMSSM, is also explored with no conclusive claims due to minimal data being available at the time of this analysis.

description: Epidemics commonly exert parasite-mediated selection and cause declines in host population genetic diversity. This could lead to evolution of resistance in the long term and smaller subsequent epidemics. Alternatively, the loss of genetic diversity could increase host vulnerability to future disease spread and larger future epidemics. Matters are made more complex by the fact that a great many host organisms produce diapausing life stages in response to environmental change (often as a result of sexual reproduction) e.g. plant seeds and invertebrate resting eggs. These diapausing stages can disrupt the relationship between past epidemics, host genetic diversity and future epidemics because they allow host dispersal through time. Specifically, temporally dispersing hosts avoid infection and thus selection from contemporary parasites, and also archive genetic variation for the future. We studied 80 epidemics in 20 semi-natural populations of the temporally dispersing crustacean Daphnia magna and its sterilizing bacterial parasite Pasteuria ramosa, and half of these populations experienced a simulated environmental disturbance treatment. We found that early initiation of diapause relative to the timing of the epidemic led to greater host genetic diversity and reduced epidemic size in the subsequent year, but this was unaffected by environmental disturbance.

description: The session focuses on Price’s early career after graduation from Yale in 1960. His brief experience at the American Heritage publishing organization is discussed, as is his work as an advance man for the Robert Wagner mayoral campaign—including in the context of his ongoing interest in journalism. Price recounts his decision to attend the University of Virginia Law School for a year, before transferring to the Yale Law School, where he was exposed to influential faculty, including Fred Rodell, Telford Taylor, and Charles Reich. A class with Reich, in particular, spurred Price’s interest in Native American law, with copyright and communications law also a topic of Price’s interest at the Yale Law School. The session focuses on Price’s experience at the Warren Commission, helping alongside other clerks to prepare its report, the summer before Price took up a clerkship for Supreme Court Justice Potter Stewart. Price’s subsequent year working for Secretary of Labor Willard Wirtz is recounted, before his move to Los Angeles to take up a law school faculty post at UCLA. The balance of the session centers on Price’s extensive work on, and scholarship about, Native American law in the 1960s and 1970s, including a decade-long representation of the Alaskan Cook Inlet Region group.

description: Using a quantum electrodynamic framework, we calculate the off-resonant scattering of a broad-band X-ray pulse from a sample initially prepared in an arbitrary superposition of electronic states. The signal consists of single-particle (incoherent) and two-particle (coherent) contributions that carry different particle form factors that involve different material transitions. Single-molecule experiments involving incoherent scattering are more influenced by inelastic processes compared to bulk measurements. The conditions under which the technique directly measures charge densities (and can be considered as diffraction) as opposed to correlation functions of the charge-density are specified. The results are illustrated with time- and wavevector-resolved signals from a single amino acid molecule (cysteine) following an impulsive excitation by a stimulated X-ray Raman process resonant with the sulfur K-edge. Our theory and simulations can guide future experimental studies on the structures of nano-particles and proteins.
Intrinsic and extrinsic measure for Brownian motion

description: Based upon the Smoluchowski equation on curved manifolds three physical observables are considered for the Brownian displacement, namely, geodesic displacement, $s$, Euclidean displacement, $δ{\bf R}$, and projected displacement $δ{\bf R}_{\perp}$. The Weingarten-Gauss equations are used to calculate the mean-square Euclidean displacements in the short-time regime. Our findings show that from an extrinsic point of view the geometry of the space affects the Brownian motion in such a way that the particle's diffusion is decelerated, contrasting with the intrinsic point of view where dynamics is controlled by the sign of the Gaussian curvature [J. Stat. Mech. P08006 (2010)]. Furthermore, it is possible to give exact formulae for $\left$ and $\left$ on spheres and minimal surfaces, which are valid for all values of time. In the latter case, surprisingly, Brownian motion corresponds to the usual diffusion in flat geometries, albeit minimal surfaces have non-zero Gaussian curvature. Finally, the two-dimensional case is emphasized due to its close relation to surface self-diffusion in fluid membranes.

description: The complex problem of climate change and its related issues calls for a creative and nuanced solution. Envisioning has been proposed as a method for deriving potential pathways forward, especially in exploring the facets of the future that people feel hopeful or pessimistic about. This study used both surveys (n=75) and interviews (n=21) to explore how environmentally-concerned young people at a large Midwestern university envision the most likely and best-case scenarios for the future, offering insights into potential sources of hope and action plans for this population. Findings from this work suggest that there is no one shared vision among environmentally-concerned young people, but that technological advancements, top-down change, and a focus on climate anxiety and hope are all critical facets for consideration of the future. These findings point to the enormous potential for universities and other institutions to use this exercise to inspire individuals to action, especially those that will live well into the future and deal with its consequences.

description: We explore the hypothesis that a passing satellite or dark matter subhalo has excited coherent oscillations of the Milky Way's stellar disk in the direction perpendicular to the Galactic midplane. This work is motivated by recent observations of spatially dependent bulk vertical motions within ~ kpc of the Sun. A satellite can transfer a fraction of its orbital energy to the disk stars as it plunges through the Galactic midplane thereby heating and thickening the disk. Bulk motions arise during the early stages of such an event when the disk is still in an unrelaxed state. We present simple toy-model calculations and simulations of disk-satellite interactions, which show that the response of the disk depends on the relative velocity of the satellite. When the component of the satellite's velocity perpendicular to the disk is small compared with that of the stars, the perturbation is predominantly a bending mode. Conversely, breathing and higher order modes are excited when the vertical velocity of the satellite is larger than that of the stars. We argue that the compression and rarefaction motions seen in three different surveys are in fact breathing mode perturbations of the Galactic disk.

description: In today's rapidly changing and increasingly complex world, companies face the challenge of ambiguity in consumer perceptions. Consequently, social media has emerged as an indispensable tool for companies to connect with their customers and gain a better understanding of their needs, wants, and desires. To remain competitive, organizations strive to establish themselves as authentic and relatable since customers tend to prefer brands they trust. This study aims to investigate the correlation between perceived brand authenticity and customer-based brand equity in the fashion retail sector. Specifically, the objective is to determine whether there is a positive association between the perceived brand authenticity and its dimensions (credibility, integrity, symbolism, and continuity) and customer-based brand equity and its dimensions (brand loyalty, brand associations, brand awareness, and perceived quality). To accomplish this objective, the study focuses on three popular fashion retail brands: Patagonia, UNIQLO, and SHEIN, each possessing varying degrees of brand authenticity. Data were collected through a Qualtrics survey from 118 college students at the University of Michigan. The findings of the study support the hypothesis that perceived brand authenticity is positively associated with customer-based brand equity. This information could prove beneficial for companies looking to enhance their brand equity. By focusing on building an authentic brand, companies can establish stronger relationships with their customers and improve their overall brand equity.

description: We present a novel reasoning calculus for the description logic SHOIQ^+---a knowledge representation formalism with applications in areas such as the Semantic Web. Unnecessary nondeterminism and the construction of large models are two primary sources of inefficiency in the tableau-based reasoning calculi used in state-of-the-art reasoners. In order to reduce nondeterminism, we base our calculus on hypertableau and hyperresolution calculi, which we extend with a blocking condition to ensure termination. In order to reduce the size of the constructed models, we introduce anywhere pairwise blocking. We also present an improved nominal introduction rule that ensures termination in the presence of nominals, inverse roles, and number restrictions---a combination of DL constructs that has proven notoriously difficult to handle. Our implementation shows significant performance improvements over state-of-the-art reasoners on several well-known ontologies.

description: UiO-66 Metal-Organic framework (MOF) has been highlighted since its synthesis for its stability and many potential applications. Lead (II) and mercury (II) water remediation are among them. In the present work, we used density functional theory calculations, cluster models, and density analysis tools to study the lead and mercury adsorption mechanism of modified UiO-66. We have included the SH (thiol), NCS (isothiocyanate), NMeTU (N-methylthiourea) and DMTD (2,5-dimercapto-1,3,4-thiadiazole) linker groups. The results show a clear trend in capturing both metals: DMTD > NMeTU > SH > NCS. For mercury adsorption, little energy difference for DMTD (bidentate) and NMeTU (monodentate) is found, while for lead, this gap is greater. Inspection of charges and descriptors as softness in conceptual DFT showed the relevance of charge transfer in mercury capture by NMeTU, making this interaction almost as strong as the bidentate fashion through sulfur and nitrogen atoms in DMTD. Lead capture shows charge transfers of lesser magnitude, so the preferred interaction fashion is bidentate. Electronic density difference maps show qualitative visualization of results and are consistent with interaction energies. Through non-covalent interaction (NCI) analysis, it was possible to conclude that at DMTD, the interaction for both metals was stronger with nitrogen atom than sulfur.

description: Domain-specific languages (DSLs) are routinely created to simplify difficult or specialized programming tasks. They expose useful abstractions and design patterns in the form of language constructs, provide static semantics to eagerly detect misuse of these constructs, and dynamic semantics to completely define how language constructs interact. However, implementing and composing DSLs is a non-trivial task, and there is a lack of tools and techniques. We address this problem by presenting a complete module system over LP for DSL construction, reuse, and composition. LP is already useful for DSL design, because it supports executable language specifications using notations familiar to language designers. We extend LP with a module system that is simple (with a few concepts), succinct (for key DSL specification scenarios), and composable (on the level of languages, compilers, and programs). These design choices reflect our use of LP for industrial DSL design. Our module system has been implemented in the FORMULA language, and was used to build key Windows 8 device drivers via DSLs. Though we present our module system as it actually appears in our FORMULA language, our emphasis is on concepts adaptable to other LP languages.

description: This thesis explores some classical aspects of extremal black holes in a diffeomorphism covariant formulation of gravity (of which general relativity is one). In particular, we first study the existence of Noether currents in the presence of Killing or gauge symmetries, and then generalize it to a theory exhibiting diffeomorphism-invariance in the context of the Noether-Wald formalism. We also explore the implication of the latter on black hole entropy for an arbitrary theory of gravity which may or may not include higher derivatives. We then study the dynamics of charged static extremal black holes in Eddington-Finkelstein coordinates and encounter the problem of stability of the horizon. From a thermodynamics standpoint, we also realize that a non-extremal black hole cannot be made extremal in a manner consistent with the third law of black hole thermodynamics. To that end, we explore the procedure of studying the near-horizon geometry in the extremal limit of a non-extremal black hole and arrive at a well-known universal result (with a caveat on some exceptions) that all extremal black holes have an AdS_2 factor in their near-horizon geometry. Motivated by the fact that the near-horizon geometry of an extremal black hole is consistent with the definitions of Wald, we study the entropy function formalism for a theory of gravity coupled to abelian gauge fields, and neutral scalars. A derivation of Wald entropy for the extremal Reissner-Nordstrom black hole in D=4 dimensions is also given. We also discuss how the entropy function formalism leads to a generalization of the attractor phenomena of black holes without explicit reference to supersymmetry or string theory. Towards the end, we provide some additional evidence for the existence of the horizon instability of an extremal black hole by looking at the redshift effect, pair production at the horizon, and mass inflation. This thesis has been written keeping in mind an advanced beginner and also includes a useful appendix that could serve as a short "primer" to delve into the field of black hole physics. There, we explore some important geometrical and (classical) thermodynamic features of rotating black holes via brute-force computation.
Electrical Contacts to Three-Dimensional Arrays of Carbon Nanotubes

description: We use numerical simulations to investigate the properties of metal contacts to three-dimensional arrays of carbon nanotubes (CNTs). For undoped arrays top-contacted with high or low work function metals, electrostatic screening is very strong, resulting in a small Schottky barrier for current injection in the top layer and large Schottky barriers for current injection in the deeper layers. As a consequence, the majority of the current flows through the top layer of the array. Our simulations show that doping of the CNT array can alleviate this problem, even without direct contact to each tube in the array; however, we find that the charge transfer length is unusually long in arrays and increases with the number of CNT layers under the contact. We also show that a bottom gate can modulate the contact resistance, but only very weakly. These results are important for the design of electronic and optoelectronic devices based on CNT arrays, because they suggest that increasing the thickness of the array does little to improve the device performance unless the film is strongly doped at the contacts and the contact is long, or unless each tube in the array is directly contacted by the metal.

A Tense Coexistence: Examining the Interracial Character of Belle Isle Park in 1920s-1940s Detroit

description: This paper explores the interracial character of Belle Isle Park in Detroit in the 1920s-1940s. It examines interactions between Black and white Detroiters on an integrated island park at a time when urban recreational spaces were often segregated. Belle Isle represented an exception to the rule of segregating more intimate activities - for example, it had an integrated beach when interracial swimming was staunchly opposed due to white fears surrounding miscegenation - however, it was not a model for interracial harmony, as the Detroit Race Riot of 1943 broke out on Belle Isle after years of tension between Black and white visitors.

description: The LUMINEU program aims at performing a pilot experiment on neutrinoless double beta decay of 100Mo using radiopure ZnMoO4 crystals operated as scintillating bolometers. Growth of high quality radiopure crystals is a complex task, since there are no commercially available molybdenum compounds with the required levels of purity and radioactive contamination. This paper discusses approaches to purify molybdenum and synthesize compound for high quality radiopure ZnMoO4 crystal growth. A combination of a double sublimation (with addition of zinc molybdate) with subsequent recrystallization in aqueous solutions (using zinc molybdate as a collector) was used. Zinc molybdate crystals up to 1.5 kg were grown by the low-thermal-gradient Czochralski technique, their optical, luminescent, diamagnetic, thermal and bolometric properties were tested.

description: It is usually assumed that information cascades are most likely to occur when an early but incorrect opinion spreads through the group. Here, we analyse models of confidence-sharing in groups and reveal the opposite result: simple but plausible models of naive Bayesian decision-making exhibit information cascades when group decisions are synchronous; however, when group decisions are asynchronous, the early decisions reached by Bayesian decision-makers tend to be correct, and dominate the group consensus dynamics. Thus early decisions actually rescue the group from making errors, rather than contribute to it. We explore the likely realism of our assumed decision-making rule with reference to the evolution of mechanisms for aggregating social information, and known psychological and neuroscientific mechanisms.

The Role of Macros in Tractable Planning

Publisher: name: arXiv
Year: 2014

description: This paper presents several new tractability results for planning based on macros. We describe an algorithm that optimally solves planning problems in a class that we call inverted tree reducible, and is provably tractable for several subclasses of this class. By using macros to store partial plans that recur frequently in the solution, the algorithm is polynomial in time and space even for exponentially long plans. We generalize the inverted tree reducible class in several ways and describe modifications of the algorithm to deal with these new classes. Theoretical results are validated in experiments.
