description: In this thesis, we study the application of modern machine learning methods to searches for supersymmetric models of physics beyond the Standard Model.
 In recent years, resonant anomaly detection methods, such as CATHODE, have gained much attention. Using weakly supervised learning, these methods are built to be signal-model agnostic. The main advantage is that they are not only sensitive to a specific signal model, the analysis is tailored to, but cover a potentially much larger region of the parameter space. These methods are most often demonstrated on signal models that contain purely localized features.
 However, the well-motivated R-parity conserving minimally supersymmetric Standard Model is often found at the tails of distributions of features such as pTmiss or HT. Pair produced gluinos with the decay chain g̃→ qq̅χ20 (χ20 → X χ10) with X either the Z or Higgs boson, light χ10 and small mass splitting between g̃ and χ20 will be used to demonstrate CATHODEs sensitivity. We, for the first time, demonstrate that CATHODE is only slightly less sensitive than multiple dedicated searches while covering multiple signal models simultaneously.
 This method can not uncover all signal models. For example the R-parity violating scalar top quark decay t̃→ t χ10 (χ10→ q q q) with weak scale χ10 and sub-TeV t̃ fails to produce features that CATHODE can reliably be applied to.
 For this signal model, we build a supervised classifier. We utilize recent innovations in computer vision, such as CoAtNet and MaxViT, that apply the self-attention mechanism to images. We represent calorimeter towers and tracks of jets as 2D images and show that the transformer-based classifiers outperform more classical convolutional neural networks in using the jet substructure to predict whether a given jet is neutralino-initiated or not. We show that replacing a CNN with MaxViT excludes up to 100 GeV of additional scalar top mass at 95% C.L. in a simple mock analysis for 100 GeV neutralinos.

description: The objective of this paper is 'open-set' speaker recognition of unseen speakers, where ideal embeddings should be able to condense information into a compact utterance-level representation that has small intra-speaker and large inter-speaker distance. A popular belief in speaker recognition is that networks trained with classification objectives outperform metric learning methods. In this paper, we present an extensive evaluation of most popular loss functions for speaker recognition on the VoxCeleb dataset. We demonstrate that the vanilla triplet loss shows competitive performance compared to classification-based losses, and those trained with our proposed metric learning objective outperform state-of-the-art methods.

 Remarks
 Necrocarcinus oklahomensis Rathbun, 1935 (Rathbun 1935: 44, pl. 11, fig. 9; see also Fraaije 2002: 913), upper Albian of the Western Interior (USA), was transferred to Cenomanocarcinus by Van Straelen (1936: 39), Stenzel (1945: 449), then by Förster (1968: 169, 176), Schweitzer et al. (2003a: 36), and Vega et al. (2007: 412, 417). The species is known by the holotype only, with a carapace characterized by marked longitudinal and epibranchial ridges, and not preserving any spines on lateral margins. Despite the fact that Stenzel (1945: table p. 449) indicated on the dorsal ridges of C. oklahomensis the same number of tubercles as in C. inflatus, he did not synonymise the two species (see under C. beardi, below).

description: This article gives certain fibre bundles associated to the braid groups which are obtained from a translation as well as conjugation on the complex plane. The local coefficient systems on the level of homology for these bundles are given in terms of the determinant of the Burau representation. De Concini, Procesi, and Salvetti [Topology 40 (2001) 739--751] considered the cohomology of the n-th braid group B_n with local coefficients obtained from the determinant of the Burau representation, H^*(B_n;Q[t^{+/-1}]). They show that these cohomology groups are given in terms of cyclotomic fields. This article gives the homology of the stable braid group with local coefficients obtained from the determinant of the Burau representation. The main result is an isomorphism H_*(B_infty; F[t^{+/-1}])-->H_*(Omega^2S^3<3>; F) for any field F where Omega^2S^3<3> denotes the double loop space of the 3-connected cover of the 3-sphere. The methods are to translate the structure of H_*(B_n;F[t^{+/-1}]) to one concerning the structure of the homology of certain function spaces where the answer is computed.

description: In 2008 and 2009 dairy farmers in the U.S. Southeast and Northeast regions filed class action antitrust lawsuits, in which they alleged that Dean Foods, the largest fluid milk processor in the country, and Dairy Farmers of America, the largest dairy cooperative in the country, engaged in anticompetitive conduct, which restricted competition in the fluid milk market in these regions. This research analyzes the behavior of Class I milk prices in ten cities located in the Southeast and Northeast regions during the period of alleged anticompetitive conduct (the pre-antitrust action period) and the period of antitrust actions (the antitrust action period). There is empirical evidence indicating that the monthly average Class I price and the monthly average cooperative Class I price are higher in the antitrust action period, as compared to the pre-antitrust action period, in all analyzed cities. The monthly average premium measured in $ per cwt and the monthly average premium measured as a percentage of the cooperative Class I price increase in the antitrust action period, as compared to the pre-antitrust action period, in all analyzed cities located in the Southeast region and in one city representing the Northeast region.

description: The infinite-genus limit of the KdV-Whitham equations is derived. The limit involves special scaling for the associated spectral surface such that the integrated density of states remains finite as $N \to \infty$ (the thermodynamic type limit). The limiting integro-differential system describes slow evolution of the density of states and can be regarded as the kinetic equation for a soliton gas.
Slow persistent mixing in the abyss

description: Knowledge about deep-ocean turbulent mixing and flow circulation above abyssal hilly plains is important to quantify processes for the modelling of resuspension and dispersal of sediments in areas where turbulence sources are expected to be relatively weak. Turbulence may disperse sediments from artificial deep-sea mining activities over large distances. To quantify turbulent mixing above the deep-ocean floor around 4000 m depth, high-resolution moored temperature sensor observations have been obtained from the near-equatorial southeast Pacific (7°S, 88°W). Models demonstrate low activity of equatorial flow dynamics, internal tides and surface near-inertial motions in the area. The present observations demonstrate a Conservative Temperature difference of about 0.012°C between 7 and 406 meter above the bottom (hereafter, mab, for short), which is a quarter of the adiabatic lapse rate. The very weakly stratified waters with buoyancy periods between about six hours and one day allow for slowly varying mixing. The calculated turbulence dissipation rate values are half to one order of magnitude larger than those from open-ocean turbulent exchange well away from bottom topography and surface boundaries. In the deep, turbulent overturns extend up to 100 m tall, in the ocean-interior, and also reach the lowest sensor. The overturns are governed by internal-wave-shear and -convection. The turbulence inertial subrange is observed to extend into the internal wave frequency band. The associated mixing is not related to bottom friction processes but to internal wave breaking and near-inertial shear. The mixing facilitates long (hours to day) and high (exceeding 100 mab) dispersal of suspended sediments.

description: We present the results of a Hubble Space Telescope (HST) survey of extended [OIII] emission in a sample of 60 nearby Seyfert galaxies (22 Seyfert 1's and 38 Seyfert 2's), selected by mostly isotropic properties. The comparison between the semi major axis size of their [OIII] emitting regions (R_Maj) shows that Seyfert 1's and Seyfert 2's have similar distributions, which seems to contradict Unified Model predictions. We discuss possible ways to explain this result, which could be due either to observational limitations or the models used for the comparison with our data. We show that Seyfert 1 Narrow Line Regions (NLR's) are more circular and concentrated than Seyfert 2's, which can be attributed to foreshortening in the former. We find a good correlation between the NLR size and luminosity, following the relation R_Maj propto L([OIII])^0.33, which is flatter than a previous one found for QSO's and Seyfert 2's. We discuss possible reasons for the different results, and their implications to photoionization models. We confirm previous results which show that the [OIII] and radio emission are well aligned, and also find no correlation between the orientation of the extended [OIII] emission and the host galaxy major axis. This agrees with results showing that the torus axis and radio jet are not aligned with the host galaxy rotation axis, indicating that the orientation of the gas in the torus, and not the spin of the black hole, determine the orientation of the accretion disk, and consequently the orientation of the radio jet.

description: Critical coagulation concentration (CCC) is a key parameter of particle dispersions, since it provides the threshold limit of electrolyte concentrations, above which the dispersions are destabilized due to rapid particle aggregation. A computational method is proposed to predict CCC values using solely electrophoretic mobility data without the need to measure aggregation rates of the particles. The model relies on the DLVO theory; contributions from repulsive double-layer forces and attractive van der Waals forces are included. Comparison between the calculated and previously reported experimental CCC data for the same particles shows that the method performs well in the presence of mono and multivalent electrolytes provided DLVO interparticle forces are dominant. The method is validated for particles of various compositions, shapes, and sizes.

description: The emergence of energy exchange-traded funds (ETFs) has provided an alternative vehicle for both energy producers and users to hedge their respective exposures to unfavorable energy price movements without opening a relative expensive futures account. While hedging with energy ETFs has been touted as a promising alternative to hedging with traditional energy futures, the question concerning the hedging effectiveness of energy ETFs versus energy futures, especially in terms of their ability to manage downside risk, remains largely unexplored. Accordingly, this study formally compares the hedging effectiveness of the two instruments in a downside risk framework from the perspective of both short and long hedgers. Two estimation methods are applied to estimate the minimum-Value at Risk (VaR) and minimum-Expected Shortfall (ES) hedge ratios: the empirical distribution function method and the kernel copula method. The empirical application focuses on four different energy commodities: crude oil, gasoline, heating oil, and natural gas.

title: Sexuality, Relationships and Reproductive Choices in Young Adults with Life-Limiting and/or Life-Threatening Conditions
Creators: name: Blackburn, M. C.

description: This thesis details an empirical exploration of how young adults with life-limiting and/or life-threatening conditions talk about sexuality, intimacy, relationships and reproductive choices; what these mean, the difficulties they encounter along an uncertain life course, their relationship experiences, and what would be helpful to assist and make their lives more meaningful. The research centres on 13 young adults aged over 16 years, featuring some, but not all, life-limiting or life-threatening conditions. These include cystic fibrosis, duchenne muscular dystrophy, other progressive neuromuscular and rare conditions, certain cancers and other genetic conditions. The research also explores the views and contributions of family supporters: two partners, ten parents and ten care practitioners, seeking their views in order to advance the young adult’s sexual and relationship fulfilment. Until recently, surviving into adulthood with a life-limiting or life-threatening condition was unusual. Young adults with these conditions are a growing population and it is timely to explore their personal choices and considerations around sexuality, intimate relationships, and reproductive choices. The research used a qualitative approach, underpinned by a life course theoretical perspective, in conjunction with the illness experience and intersectionality with sexuality on an uncertain life course, to make sense of the participants’ varied and personal contributions. What emerged was a picture of the transitions which occur from childhood to adulthood, from comparative wellness to progressive illness, uncertainty about their life course and importantly, their sexuality. The findings suggest that the voices of this group are insufficiently heard and that there is a gap in the provision of information with respect to their transition from childhood to adulthood, particularly in relation to their sexuality and reproductive choices. As this group strives for independence and sexual citizenship, efforts need to be congruent with and grounded in the views of those most personally involved, the young adults themselves.
title: Dinucleotide TG Repeats and 5' Splice Site Definition
Creators: name: Passoni, Monica
Publisher: name: The Open University
Year: 2011

description: During the pre-mRNA splicing process introns are removed and exons joined together in the resulting mature mRNA, which is then exported to the cytoplasm and translated into proteins. Several motifs in the nucleotide sequences near the exon-intron boundaries are required for proper exon definition including the 3’ and 5’ splice site consensus sequences (3’SS and 5’SS), which recruit basic splicing factors. In addition, auxiliary splicing regulatory elements, located in the upstream or downstream region of an exon, further influence exon recognition through the recruitment of additional binding proteins. This study shows that intronic UG repeat elements in proximity of the 5’SS of an exon can function as splicing regulatory elements, generally enhancing the inclusion of the upstream exon in the final mRNA through the recruitment of UG repeats-binding proteins. In particular, the strength of the 5’SS consensus sequence affects this UG repeats-mediated splicing regulation. Furthermore, this study reveals that the UG repeats-binding protein TDP-43 acts as splicing modulator either activating of inhibiting the splicing events in different minigene systems. In fact, in presence of a disease-causing mutation at the 5’ end of the BRCA1 exon 12 TDP-43 enhances exon inclusion, acting as splicing enhancer. Alternatively, overexpression of TDP-43 can exert an inhibitory effect on splicing by promoting exon skipping in two newly identified TDP-43 target exons (RXRG exon 7 and ETF1 exon 7). In conclusion, this study provides positive proof of concept that UG repeats located in the downstream region of poorly defined exons help 5’SS definition. Additionally, the study characterizes the role of TDP-43 in various splicing systems presenting the UG repeat-binding sites, with the practical application of evaluating a putative splicing-affecting pathological mutation.
title: Identification and Characterization of Histone H3K36 Demethylases in Drosophila melanogaster
Creators: name: Lin, Chia-Hui
Publisher: name: The Open University
Year: 2011

description: Covalent modifications of histones, such as acetylation, methylation, phosphorylation and ubiquitination, have an important role in regulating gene expression. Histone methylation is implicated in both gene activation and repression depending on the methylation site and the state of methylation (Li et al., 2007a). Historically, histone methylation was considered to be a static modification. Recent discoveries of histone demethylases demonstrate that histone methylation is reversible. Numerous studies have shown that dynamic regulation of histone methylation plays an important role in many cellular processes (Cloos et al., 2008). However, mechanisms governing the targeting and regulation of histone demethylation remain elusive.

In this thesis, I identified two Drosophila melanogaster JmjC domain-containing proteins, dKDM4A and dDKM4B, which are histone H3K36 demethylases. Affinity purification and mass spectrometry analysis revealed that Heterochromatin Protein 1a (HP1a) associates with dKDM4A. I found that the chromoshadow domain of HP1a and a HP1-interacting motif within dKDM4A are responsible for this interaction. HP1a stimulates the histone H3K36 demethylation activity of dKDM4A and this stimulation depends on HP1a binding to the H3K9me. Loss of HP1a leads to increased level of histone H3K36me3. By chromatin immunoprecipitation using an antibody against H3K36me3 in wild type and dKDM4A mutant embryos, I identified candidate target genes of dKDM4A. A subset of dKDM4A target genes are also shown to be bound by HP1a, suggesting dKDM4A-HP1a complex may function in regulating H3K36 levels at these genes.
title: Functional Characterization of Non-Coding RNAs in the Mammalian Retina

description: Long non-coding RNAs (IncRNAs) are emerging as regulators of a number of basic cellular pathways. Several IncRNAs are selectively expressed in the developing retina, although little is known about their functional role in this tissue. During my PhD thesis I characterized the expression pattern of three retinal-lncRNAs, namely Six3os, Otx2os and Vax2os in the developing mouse retina. Opposite Strand (OS) transcripts are transcribed in the opposite direction of protein-coding genes, in this case Six3, Otx2 and Vax2, respectively. Furthermore, I performed a comprehensive functional study for Vax2os1, the most abundant transcript from the Vax2os cluster, whose expression is restricted to the mouse ventral retina. I demonstrated that misexpression of Vax2os1, both in vitro and in vivo, determines cell cycle alterations in photoreceptor progenitor cells. In particular, the overexpression of Vax2os1 in the developing postnatal mouse retina caused an impaired cell cycle progression of photoreceptor progenitors toward their final committed fate and a consequent delay of their differentiation processes. At later developmental stages, this perturbation was accompanied by an increase of apoptotic events in the photoreceptor cell layer, in comparison with control retinas, without affecting the proper cell layering in the adult retina. Similar results were observed in mouse photoreceptor-derived 661W cells in which Vax2os1 overexpression resulted in an impairment of the cell cycle progression rate and cell differentiation. Based on these results, I conclude that Vax2os1 seems to ensure proper control of the cell cycle progression of photoreceptor progenitor cells in the ventral retina. Therefore, I propose Vax2os1 as the first example of IncRNA that acts as a cell cycle regulator in the mammalian retina during development.

 Remarks
 Wright (1997: 135) was “inclined to abandon the distinction of the two subgenera”, based on post-rostral slits found in the type species of both Paranecrocarcinus and Pseudonecrocarcinus, thus a not really distinctive feature of the latter. According to Fraaije (2002: 916) “ Pseudonecrocarcinus has thus lost its validity as a genus”, since it is a junior synonym of Paranecrocarcinus. Schweitzer et al. (2003a: 32, 36) misinterpreted Fraaije’s words and regarded them as separate genera considering that “the possession of these carapace slits is highly distinctive” without realising that both genera possess them. Concludingly Wright (1997), Fraaije (2002), and Schweitzer et al. (2003a) agreed on the synonymy.
 Thus Pseudonecrocarcinus stenzeli Bishop, 1983 (Bishop 1983a: 49, fig. 8B, pl. 1, figs 3-5; 1986: 136, table 1), lower Albian of Texas, has to be assigned to Paranecrocarcinus.

title: Role of the Transcription Factor CREB in the NMDA Receptor Antagonist-Induced Attention Deficits
Creators: name: Pozzi, Laura
Publisher: name: The Open University
Year: 2011

description: This thesis is the result of a multidisciplinary approach which combines behavioral, biochemical and neurochemical assays to identify and delineate the molecular mechanisms involved in the control of attention. Blockade of prefrontocortical glutamate NMDAR is associated with attentional performance deficits as assessed in a task capable of measuring selective attention and response control such as the five choice serial reaction time (5-CSRT) task. I investigated whether phosphorylation of proteins linked to the PKA/CREB pathway in the prefrontal cortex (PFC) and in subcortical regions may be affected by NMDAR blockade. Pharmacological experiments using western blot and immunohistochemical techniques clearly demonstrated that increased CREB phosphorylation (p-CREB) in the PFC but not in subcortical regions may be associated to deficits in attention performance caused by the blockade of prefrontocortical NMDAR with the selective antagonist CPP. Attempts has been made to identify the intracellular pathways responsible for CPP-induced p-CREB changes by examining different protein kinases upstream to CREB such as protein kinase A (PKA), extracellular regulated protein kinases 1/2 (ERK1/2) and calcium/calmodulin kinase II (CaMKII). However, the precise role of these kinases in NMDAR antagonist induced changes in p-CREB is unclear and deserves further studies. The hypothesis that attention deficits induced by NMDAR blockade in the PFC might reflect excessive glutamate (GLU) release in the PFC was investigated by assessing the effects of intracortical CPP on attention, GLU release and p-CREB under basal conditions and in rats pre-treated with the mGlu2/3 receptor agonist LY379268. The results provide evidence that enhanced GLU release in the PFC and CREB phosphorylation are associated to attention deficit. As there are evidences that drug responses may be modulated by the behavioural state of animals, I evaluated the effect of blockade of NMDAR in the PFC on p-CREB in rats performing the 5-CSRT task. Intriguingly, I found that in these rats CPP-induced p-CREB in the PFC was decreased as opposed to the increase found in behaviourally naive rats at the same time point, suggesting that the direction of CPP-induced p-CREB changes critically depends on the behavioural state of animals. Moreover CPP-induced cognitive impairments were prevented by the intracortical administration of Sp-cAMP suggesting that the activation of the PKA/CREB cascade in the PFC is required for the correct performance of the task. In conclusion the present thesis support the role of CREB and provide new information on the mechanisms involved in the control of attention and executive functions associated with some neuropsychiatric disorders.

Mexican Revolution

description: The University of Texas at Austin General Libraries and its Nettie Lee Benson Latin American Collection have preserved on microfilm 227,930 pages from 560 Mexican newspaper titles which date primarily from 1900 to 1929. The project, which ran from October 2000 through September 2002, was supported, in part, by a grant from the National Endowment for the Humanities (PA-23563-00). The majority of the newspapers (326, 58.2%) were published in the Distrito Federal; but a substantial number (234, 41.8%) were published in Mexican cities from twenty-eight states. Of particular interest are the titles that were published during the pivotal decade of the Mexican Revolution, 1910 through 1919, many of which are from cities other than Mexico City. These newspaper issues are rarely held in U.S. libraries, and some are uniquely held in the Benson Collection - 489 newspaper titles in this set came from its holdings. The Library of Congress, Tulane University, Harvard University, and Boston Public Library provided other titles and supplementary issues. Tulane University alone supplied 61 unique titles, principally newspapers from Chiapas and Yucatán. The Library of Congress lent several unique titles as well as many supplementary issues, especially from the Distrito Federal. Well-known, long-running newspapers were omitted from the project if they were available on microfilm through U.S. research institutions. The arrangement of the newspapers within the microfilm is alphabetical by state and city thereunder (reels 1 to 125) with newspapers published in the Distrito Federal following (125 to 344). Addenda and errata appear in reel 345. This guide follows that arrangement and also contains an alphabetical list of the titles, which serves as an index to the newspapers. The reel and frame number in the alphabetical list refers to the first issue microfilmed and, if applicable, to the reel of addenda and errata; different newspapers with the same title are listed separately. The microfilm is available for purchase or through interlibrary loan.

description: Neutron star (NS) mergers provide us with information rich in physics using multi-messenger astrophysical observations. One of the probable remnants of such a merger is a differentially rotating hot hypermassive neutron star. The stability of the merger remnant depends crucially on the underlying Equation of State (EoS) and thus provides a method to probe the nature of dense matter in NSs. In this work, we search for possible signatures of strangeness containing matter in the NS interior on the secular stability of the merger remnant. We also use recently proposed methods to make a rough estimate the collapse time of the merger remnant and the threshold mass above which the merger promptly collapses to a black hole.

description: This case study research was undertaken as an initial step towards studying the critical factors that influence the adoption of value-added as an additional enterprise by small farmers in North Carolina. Human factors such as age, years in farming, and level of education were perceived to be common elements. Production variables such as total acreage and value-added marketing were also deemed to be common features amongst the operators. The need to generate value-added funding, supply consumer demands, and expand core business operations were often mentioned among the goals of operators implementing value-added activities. Amongst the value-added operators, land availability, acquiring employee assistance, and weather calculations were cited as barriers or problems faced at their value-added operations. The biggest driving forces behind the operator’s view of success was passion for their value-added growth and educational agritourism.

description: Die Auseinandersetzung mit Ausdrucksformen von Popularität steht seit einigen Jahren vermehrt im Fokus der kulturwissenschaftlichen Forschung. Ausgehend von der Gegenwärtigkeit und Ubiquität der Populärkultur – gemeinhin als Proprium der Modernität verstanden und gedacht – fragt der vorliegende Sammelband erstmals grundsätzlich nach der Applizierbarkeit der Kategorie „populär“ auf die Epochen Mittelalter und Frühe Neuzeit. Die zeitgenössische Theoriebildung zur Popkultur bildet den Ausgangspunkt für die versammelten Beiträge, in interdisziplinärer Perspektive sowohl auf übergreifend theoretisch-methodischer Ebene als auch in Form von Fallstudien Popularisierungsprozesse zu beleuchten. Im Zentrum stehen dabei insbesondere visuelle Artefakte und Phänomene, die hinsichtlich ihrer Distribution, Reproduktion, Variation und Serialisierung thematisiert werden. Angerissen werden Aspekte der Politisierung des Populären, seiner normierenden Wirkmacht sowie seines anarchischen Potenzials.

description: The first zine in this project was a series of hundred-word reflections (Lauren & Berlandt, 2019) [“four hundreds for me”] I wrote sitting under my desk at 7am in the middle of winter, underneath my a/r/tographic playmat. Somewhat compulsively, I wrote zine after zine as a sense-making exercise (Greene, 1987; Haynes, 2001), initially to examine my inability to participate in my own research. The turn occurs when I see these zines as a/r/tographic openings (Irwin, 2013) for and as research.These zines unfolded to story reasons why I could not participate in my own research, including being tired [“four hundreds for me”], being overwhelmed [“how to do dishes”], discomfort around being a working mother [“Re/searching, art/making, m/othering”] and the feeling of drowning [“What Are You Doing in Gloomy Hollow?”]. I explored my inability to participate in a living inquiry that felt haunted by postpartum psychosis and the unravelling of significant childhood trauma [“eeexxxccceessss” and “[sur]renderings: contiguity and living inquiry”]. I folded a longtime friend into the process [“how to make a zine when your life is falling apart”] and started to see the boundaries between my personal zine-making and the zines made as da/r/ta by participants shift; they started to overlap. I started to see their grief for their schools mirrored in my own grief for my research [“an ode to our goals for education (or something”] and my drowning in motherhood as contiguous with their drowning in schools [“neither of these wolves can do it”].This 8-page zine contrasts the complexities of teaching and mothering.

description: Nuts such as almonds, pecans, walnuts, and pistachios are available in the U.S. market in different forms and brands. There are well-known national brands as well as not-so well-known private label and store brands. Nut producing firms compete for market share and strategically price, brand, advertise and position products in the market. Conventional brand-level analysis of such markets is achieved through calculation of market power and price cost margins assuming the presence of pure strategy Bertrand-Nash Equilibrium in prices. This is supported by a set of prior assumptions with regards to the structure of the market and oftentimes these are too restrictive, because pricing decisions are made in a complex multivariate situation with numerous interactions between variables that determine the prices and prices themselves. In this study, using 2015 Nielsen scanner data for nut products, complex causal relationships among brand level prices are estimated using cutting-edge machine learning algorithms. Also within this method, the concept of Markov Blankets is used to identify specific brands that are immediately important for a given brand. Several national brands were identified as a direct cause of the price of store brands. Even though store brands were associated with the highest market share, they had no influence on any other brands’ pricing decision and strategy.

description: Motivated with various responses of world governments to COVID-19, here we develop a toy model of the dependence epidemics spreading on the availability of tests for disease. Our model, that we call SUDR+K, is based on usual SIR model, but it splits the total fraction of infected individuals into two components: those that are undetected and those that are detected through tests. Moreover, we assume that available tests increase at a constant rate from the beginning of epidemics but are consumed to detect infected individuals. Strikingly we find a bi-stable behavior between a phase with a giant fraction of infected and a phase with a very small fraction. We show that the separation between these two regimes is governed by a match between the rate of testing and a rate of infection spread at given time. We also show that the existence of two phases does not depend on the mathematical choice of the form of the term describing the rate at which undetected individuals are tested and detected. Presented research implies that a vigorous early testing activity, before the epidemics enters into its giant phase, can potentially keep epidemics under control, and that even a very small change in rate of testing can increase or decrease the size of the whole epidemics of various orders of magnitude. For the real application of realistic model to ongoing epidemics, we would gladly collaborate with field epidemiologists in order to develop quantitative models of testing process.

description: The number of farmers’ markets in the United States continue increasing but at a decreasing rate. Additionally, although the number of farms with direct to consumer (DTC) sales, including farmers’ markets sales, increased by about 6% between 2007 and 2012, DTC sales did not change in this same time period. For those vendors still using farmers’ markets as their main marketing channel, a better understanding on how to price their products could influence their likelihood of survival under a more competitive environment. The main purpose of this study is to identify the factors influencing prices at farmers’ markets, particularly Tennessee farmers’ markets prices. Specifically, we evaluated how factors such as weather, location, and consumer characteristics influence tomato prices at Tennessee farmers’ markets. The midrange of weekly per pound tomato prices at Tennessee farmers’ markets between 2013 and 2015, household characteristics, and weather information were used for this analysis. A random effects panel data regression was used to evaluate the factors influencing tomato prices at Tennessee farmers’ markets. Results suggest the factors influencing tomato prices at Tennessee farmers’ markets are potential customers’ age, household income, and seasonality.
title: Regulators of Centromeric Nucleosomes in Saccharomyces cerevisiae
Creators: name: Shivaraju, Manjunatha
Publisher: name: The Open University
Year: 2011

description: The centromere is a specialized chromosomal structure that regulates faithful chromosome segregation during cell division, as it dictates the site of assembly of the kineto-chore. In all organisms, the centromeric nucleosomes are specified by a H3 variant, known as Cse4 in budding yeast. How these centromeric nucleosomes are assembled and perpetuated is only beginning to be understood. Scm3 is an evolutionarily conserved essential inner kinetochore protein that has been shown to be important for centromere specification. Plasmid supercoiling assays performed in vitro with recombinant proteins demonstrate that Scm3 can act as a Cse4-specific nucleosome assembly factor. Assembly activity depends on an evolutionarily conserved domain of Scm3 and the centromere targeting domain (CATD) of Cse4, but is sequence independent. Interestingly, micrococcal nuclease digestion of Scm3 assembled Cse4 nucleosomes reveals that less DNA is protected compared to Nap 1 assembled Cse4 nucleosomes, suggesting structural differences. Fluorescence correlation spectroscopy in combination with brightness measurements and confocal imaging experiments in live cells revealed that centromeres at G1 phase have one copy of Cse4 per centromeric nucleosome whereas two copies are detected at anaphase. The apparent structural change occurs at the “metaphase to anaphase” transition. We propose a model in which the structure and composition of centromeric nucleosomes is cell cycle regulated. Our model reconciles experimental evidence for the existence of both the hemisome and the octasome.

description: We present a detailed observational strategy for finding Near Earth Objects (NEOs) with the Sloan Digital Sky Survey (SDSS) telescope. We investigate strategies in normal, unbinned mode as well as binning the CCDs 2x2 or 3x3, which affects the sky coverage rate and the limiting apparent magnitude. We present results from 1 month, 3 year and 10 year simulations of such surveys. For each cadence and binning mode, we evaluate the possibility of achieving the Spaceguard goal of detecting 90% of 1 km NEOs (absolute magnitude H <= 18 for an albedo of 0.1). We find that an unbinned survey is most effective at detecting H <= 20 NEOs in our sample. However, a 3x3 binned survey reaches the Spaceguard Goal after only seven years of operation. As the proposed large survey telescopes (PanStarss; LSST) are at least 5-10 years from operation, an SDSS NEO survey could make a significant contribution to the detection and photometric characterization of the NEO population.

description: With respect to testing linear regression disturbances, two methods of test construction have recently been found to work well. These are traditional asymptotic tests based on the marginal likelihood or equivalently the likelihood of the maximal invariant and point optimal or approximate point optimal (APO) tests. The former approach has been found to work well for testing for random regression coefficients in the presence of autocorrelated errors. This paper constructs APO invariant (APOI) tests for this testing problem and extends the previous Monte Carlo study to include APOI tests. We conclude that for this testing problem, the extra work required to apply APOI tests hardly seems worthwhile, particularly for larger sample sizes.

description: We present the first results of a large-scale survey, using the UV/blue sensitive LRIS-B spectrograph on the Keck I telescope, of galaxies in the redshift interval 1.4=2.20+/-0.32 and `BM' galaxies at =1.70+/-0.34; currently we have spectroscopically confirmed 749 of the former and 114 of the latter. We also present initial results of deep near-IR photometry and spectroscopy, from which we show that z~2 galaxies are significantly redder in their optical/IR colors compared to similarly UV-selected galaxies at z~3, but that the characteristics of their galaxy-scale outflows are quite similar. We illustrate by example the information which can be deduced on the stellar populations, metallicities, and kinematics of `redshift desert' galaxies from easily accessible rest-frame far-UV and rest-frame optical spectra. Far from being hostile to observations, the universe at z~2 is uniquely suited to providing information on the astrophysics of star-forming galaxies and the intergalactic medium, and the relationship between the two [abridged].
