title: Development of Genetic Goat and Hamster Models of Atrial Fibrillation and Long QT Syndrome; and Genetic Hamster Models of Middle East Respiratory Syndrome
Creators: name: Rasmussen, Dane A.
Publisher: name: Utah State University
Year: 2015

description: Atrial fibrillation, long QT syndrome, and Middle East Respiratory Syndrome are three deadly human diseases for which genetic animal models are needed. From elucidating disease pathogenesis to facilitating the development of treatments, animal models are crucial for studying human disease. One of the most effective ways to generate specific animal models is through genetic modification. Historically, mice have been most widely used as genetically modified models, despite a number of limitations. New gene editing technologies such as CRISPR/Cas9 have made developing alternative genetic models that better recapitulate some human diseases better and more feasible. In this thesis, I describe my efforts to develop genetically modified goat and hamster models for atrial fibrillation and long QT syndrome, and genetically modified hamster models for Middle East Respiratory Syndrome. For long QT syndrome model development, I knocked out the KCNQ1 gene in goat fetal fibroblast cells and baby hamster kidney cells using the CRIPSR/Cas9 system. The knockout results in loss-of-function mutations, a known cause of human long QT syndrome. The edited goat fibroblast cells will be nuclear donors for future cloning experiments to produce live goats possessing the KCNQ1 knockout. The CRISPR gene targeting sgRNA/Cas9 vector, specific for the hamster KCNQ1, has been used for pronuclear injections to produce KCNQ1 knockout hamsters. For atrial fibrillation model development, I designed a single-stranded donor oligonucleotide that generates a KCNQ1 gainof-function mutation resulting in the disease. This oligonucleotide was injected into hamster embryos along with the KCNQ1 sgRNA/Cas9-expressing vector to generate hamsters containing the gain-of-function mutation. Finally, for Middle East Respiratory Syndrome model development, I established a breeding colony of human DPP4 transgenic hamsters in the STAT2 knockout background. Human DPP4 transgenic hamsters are susceptible to MERS-CoV infection, showing mild clinical signs and allowing viral replication in lung tissue. Giving these hamsters a STAT2 knockout background should promote a more severe disease progression. For all three diseases, the foundations for the development of genetic animal models have been laid.

description: Межозерье — территория на северо-западе Европейской России между Ладожским, Онежским и Белым озерами, где на протяжении более чем тысячелетнего периода осуществлялось этнокультурное взаимодействие славянского и прибалтийско-финского населения — предков современных вепсов и карел. Актуальное значение для историко-этнографических исследований имеют этнонимические и топонимические предания, бытующие в среде как русского, так и прибалтийско-финского населения Межозерья. Их ценность определяется недостаточным отражением этнокультурной истории региона в письменных источниках, а также возможностью изучения народных представлений об этноисторических событиях. В статье используются как известные исследования, так и собственные полевые материалы автора, некоторые впервые вводятся в научный оборот. Различные эпохи получили неодинаковое отражение в фольклоре, что свидетельствует о степени их значимости в традиционном мировоззрении. В преданиях Межозерья прослеживаются как этнические, так и локальные особенности, отражающие местное своеобразие. Среди рассматриваемых преданий выделяются произведения, интерпретирующие возникновение этнонимов вепсов, повествующие об иноэтничных врагах и выдающихся исторических персонажах, объясняющие появление различных природно-географических и рукотворных объектов, в том числе населенных пунктов, а также трактующие в русле народной этимологии названия топонимов. Проведенное исследование показывает продуктивность использования преданий для изучения этнокультурной истории и выявляет наличие в фольклорной традиции региона элементов, отражающих представления местного населения о своей этнической идентичности, историческом прошлом и этнокультурном взаимодействии. Различные эпохи получили неодинаковое отражение в фольклоре, что свидетельствует о степени их значимости в традиционном мировоззрении. При этом очевидно как наличие общего фольклорного наследия, так и локальных различий, связанных с особенностями формирования отдельных этнолокальных групп населения, представляющих взаимоотношения с соседями, а также трактующих реалии окружающего мира.

description: В статье рассматривается сюжетно-тематический цикл устных рассказов старообрядцев Бурятии о межэтнических контактах семейских и бурят на хозяйственном и бытовом уровнях. Актуальность статьи обусловлена необходимостью исследования фольклора русских в иноэтнической среде. Новизна представленной статьи обусловлена отсутствием исследований устных рассказов старообрядцев Бурятии о межэтнических взаимоотношениях с коренным населением. В работе выявляются основные мотивы, структурирующие тексты, определяется прагматическое назначение рассказов о взаимоотношениях с бурятами. Показано, что при всей исторической неоднозначности межнациональных отношений для соответствующей группы устных рассказов характерно присутствие идеи комплиментарных отношений между русскими-старообрядцами и бурятами во всех сферах жизни. Рассказы же о какихлибо межнациональных конфликтах находятся на периферии исторического сознания носителей традиции. Делается вывод, что в фольклорную традицию вошли стереотипированные тексты, с прагматической точки зрения содержащие этнически важную информацию, транслируемую во времени посредством определенного набора мотивов.
title: Investigation of the Tailoring Steps in Pradimicin Biosynthesis

description: The actinobacteria Actinomadura hibisca synthesizes the natural products pradimicin A-C through a type II polyketide biosynthetic pathway. Eight tailoring enzymes in pradimicin biosynthesis have been investigated in this work, including PdmJ, PdmW, PdmN, PdmT, PdmO, PdmS, PdmQ and PdmF. PdmJ and PdmW were characterized as cytochrome P450 hydroxylases that catalyze the incorporation of two hydroxyl groups at C-5 and C-6, respectively. These enzymes worked synergistically and their co-expression significantly improved the efficiency of the hydroxylation steps. PdmN is an amino acid ligase that accepts a variety of substrates and ligates a D-alanine moiety to C-16 to form the corresponding derivatives. PdmS and PdmQ were functionally identified as Oglycosyltransferases. Disruption of pdmS in the genome of A. hibisca generated a biosynthetic precursor without sugar moieties, which validated that PdmS is the first glycosyltransferase that attaches the first sugar to the 5-OH of pradimicins. In contrast, disruption of pdmQ led to the synthesis of pradimicin B, confirming that PdmQ was responsible for attaching the D-xylose moiety to the 3'-OH of the first sugar portion in pradimicins. Naturally, the first sugar moiety 4',6'-dideoxy-4'-amino-D-galactose of pradimicin A and B is methylated at 2'-NH. When the expression of PdmO was compromised, the mutant strain produced mainly pradimicin C, which contains the 4',6'- dideoxy-4'-amino-D-galactose in its structure. This suggested that PdmO was responsible for the N-methylation of the amino sugar. PdmF was identified as the C-11 Omethyltransferase. Moreover, PdmT was confirmed to be an O-methyltransferase through gene disruption and in vitro biochemical reactions. PdmT methylates the 7-OH to form a methoxy group that in a later step is removed to generate the pradimicin aglycon. In summary, this research has identified eight important pradimicin biosynthetic enzymes that are involved in various tailoring steps in pradimicin biosynthesis. Several new pradimicin analogues has been generated by manipulating these enzymes. Their enzymatic properties and collaborative actions were investigated. These results not only provide new insights into type II polyketide biosynthetic pathways, but also enable rational engineering of the pradimicin biosynthetic pathway to create new analogues for drug development.

description: We investigate the environment of the nearby (d ~ 40Mpc) broad-lined Type Ic supernova SN 2009bb. This event was observed to produce a relativistic outflow likely powered by a central accreting compact object. While such a phenomenon was previously observed only in long-duration gamma-ray bursts (LGRBs), no LGRB was detected in association with SN 2009bb. Using an optical spectrum of the SN 2009bb explosion site, we determine a variety of ISM properties for the host environment, including metallicity, young stellar population age, and star formation rate. We compare the SN explosion site properties to observations of LGRB and broad-lined SN Ic host environments on optical emission line ratio diagnostic diagrams. Based on these analyses, we find that the SN 2009bb explosion site has a very high metallicity of ~2x solar, in agreement with other broad-lined SN Ic host environments and at odds with the low-redshift LGRB host environments and recently proposed maximum metallicity limits for relativistic explosions. We consider the implications of these findings and the impact that SN 2009bb's unusual explosive properties and environment have on our understanding of the key physical ingredient that enables some SNe to produce a relativistic outflow.

Материалом для исследования являются устные мифологические рассказы, легенды и предания, записанные в Павлодарской, Акмолинской и Восточно-Казахстанской областях в конце ХХ — начале ХХI столетия. Характер межэтнических взаимодействий рассматривается в тесной связи с историей миграционных процессов, а также характером контактов соседствующих народов. История русско-казахских взаимоотношений отражается в преданиях, которые иллюстрируют разные стадии межэтнической коммуникации (противостояние, плюрализм, адаптация, интеграция). В процессе анализа преданий и быличек выявляется интерференция на уровне сюжетов, мотивов, персонажей, языка, интерпретации событий. Исследование особенностей бытования быличек в полиэтническом регионе демонстрирует различные формы заимствования, возникновение новых русско-казахских версий известных сюжетов, а также ассимиляцию чужой системы верований в контексте своей традиции.
title: A Spatiotemporal Mountain Pine Beetle Outbreak Model Predicting Severity, Cycle Period, and Invasion Speed
Creators: name: Duncan, Jacob P.
Publisher: name: Utah State University
Year: 2016

description: The mountain pine beetle (MPB, Dendroctonus ponderosae), a tree-killing bark beetle, has historically been part of the normal disturbance regime in lodgepole pine (Pinus contorta) forests. In recent years, warm winters and summers have allowed MPB populations to achieve synchronous emergence and successful attacks, resulting in widespread population outbreaks and resultant tree mortality across western North America. We develop an age-structured forest demographic model that incorporates temperature-dependent MPB infestations: the Susceptible-Infested-Juvenile (SIJ) model. Stability of fixed points is analyzed as a function of population growth rates, and indicates the existence of periodic outbreaks that intensify as growth rates increase. We devise analytical methods to predict outbreak severity and duration as well as outbreak return time.
To assess the vulnerability of natural resources to climate change, we develop a thermally-driven mechanistic model to predict MPB population growth rates using a distributional model of beetle phenology in conjunction with criteria for successful tree colonization. The model uses projected daily minimum and maximum temperatures for the years 2025 to 2085 generated by three separate global climate models. Growth rates are calculated each year for an area defined by latitude range 42° N to 49° N and longitude range 108° W to 117° W on a Cartesian grid of approximately 4km resolution. Using these growth rates, we analyze how the optimal thermal window for beetle development is changing with respect to elevation as a result of climate change induced warming. We also use our combined model to evaluate if thermal regimes exist that would promote life cycle bivoltinism and discuss how yearly growth rates would change as a result.
Outbreaks of MPB are largely driven by host tree stand demographics and spatial effects of beetle dispersal. We augment the SIJ model to account for the spatial effects of MPB dispersal throughout a forest landscape by coupling it with a Gaussian redistribution kernel. The new model generates a train of sustained solitary waves of infestation that move through a forest with constant speed. We convert the resulting integrodifference equation into a partial differential equation and search for travelling wave solutions. The resulting differential equation provides predictions of the shape of an outbreak wave profile and of peak infestation as functions of wave speed, which can be calculated analytically. These results culminate in the derivation of an explicit formula for predicting the severity of an outbreak based on the net reproductive rate of MPB and host searching efficiency.

description: A weak entwining structure in a 2-category K consists of a monad t and a comonad c, together with a 2-cell relating both structures in a way that generalizes a mixed distributive law.A weak entwining structure can be characterized as a compatible pair of a monad and a comonad, in 2-categories generalizing the 2-category of comonads and the 2-category of monads in K, respectively. This observation is used to define a 2-category Entw^w(K) of weak entwining structures in K. If the 2-category K admits Eilenberg-Moore constructions for both monads and comonads and idempotent 2-cells in K split, then there are pseudo-functors from Entw^w(K) to the 2-category of monads and to the 2-category of comonads in K, taking a weak entwining structure (t,c) to a `weak lifting' of t for c and a `weak lifting' of c for t, respectively. The Eilenberg-Moore objects of the lifted monad and the lifted comonad are shown to be equivalent. If K is the 2-category of functors induced by bimodules, then these Eilenberg-Moore objects are isomorphic to the usual category of weak entwined modules.

description: Intimacy and family have been pillars of the North American fur trade since its conception. This is especially true for fur trading companies centered in Canada, specifically the Hudson’s Bay Company and the Northwest Company. Kinship ties formed through intimate relations between European fur traders and indigenous women allowed the fur trade to flourish and created an environment for stable, mixed heritage family units to emerge. As mixed heritage children grew into adulthood, they learned to identify with both sides of their parental cultures. However, the connections they formed with each other proved the most valuable and a separate, distinct culture emerged. In Canada this group of people are known as the Métis, a French word meaning mixed. The fur trade continued its move west and eventually reached the Pacific Ocean. This region known as the Pacific Northwest was the farthest removed from fur trade headquarters in Montreal and was home to many different Indigenous Nations. These nations, in combination with fur traders many of whom where Métis, also created families and a new culture once again came into being. It shared aspects of Métis, European, and indigenous cultures, but was something distinctly new. Through the examination of education, kinship ties, language and borders, this groups understanding of self and community came into focus.

Краткий обзор истории собирания печорской причети показывает, что более репрезентативным выглядит корпус записей среднепечорских плачей (Усть-Цилемский район Республики Коми), источниковая база нижнепечорских причитаний выглядит очень скромно. Из почти 180 опубликованных текстов лишь три сопровождены нотной расшифровкой и один образец представлен в аудиоизданиях. В целом же за без малого столетний отрезок времени собран богатый материал по печорской причети (не менее 500 единиц записи), достойный как отдельной публикации текстов и нотировок с аудиоприложениями, так и комплексного филолого-музыковедческого исследования.

description: Цель этой статьи — представить предварительные результаты исследования повседневной жизни пастухов, которое автор ведет с 2015 г. в области истории, миграции и культурного наследия меньшинства влахов, населяющего районы от Албании до Северных Карпат. Один из этапов исследования включает изучение повседневной жизни и ритуалов горцев, живущих на польской стороне Карпат. В статье рассматриваются вопросы, касающиеся структуры и пространственно-временной символики современной пастушеской хижины, в том числе моменты, когда современные пастухи начинают и заканчивают выпас скота, а также мир топографических представлений пастухов. Исследование проводилось на пастушеских стоянках Спиша, Оравы, Подгале, Живецкого повята и Силезских Бескид в Польше в 2015–2018 гг. Во всех случаях автор применял методы качественного исследования, в основном стандартные и глубинные интервью с пожилыми и молодыми пастухами, а также включенное наблюдение (открытое и скрытое) во время праздников и встреч пастухов в разных ситуациях (в храмах, во время съездов гуралей и валахов, тематических встреч на горных пастбищах). Данные методы были дополнены aнaлизом визуальных источников, снятых «в поле», найденных в Интернете, а также предоставленных автору любителями, увлеченными темой пастушества. Исследования показали, что современное скотоводство колеблется между двумя полюсами: традиционным, который позволил сохранить многие элементы из прошлого (влашское право), и современным.
Absolute emission intensity studies on the halogen afterglows and excited molecular oxygen
Creators: name: Browne, Robert James
Publisher: name: University of British Columbia
Year: 2011

description: The bromine afterglow emission was studied using the discharge-flow technique. The spectrum of discharged bromine was observed to extend from 6000Å to 22000Å and has been attributed to the Br₂ (₃Π₀⁺u→¹Ε⁺g) and Br₂(³Π₁u→Σ⁺g) transitions. The dependence of the emission intensity on atom concentration was observed to vary between I ∝ [Br]²•º ±º•¹ at short wavelengths, and I∝[Br]¹•⁵±º•¹ in the long wavelength region of the spectrum. In the pressure range studied (O.5 to 2 torr), the intensity was found to be independent of the molecular bromine concentration. By measuring the absolute emission intensity between 6000Å and 12000Å, values of the apparent rate constant, defined as kapp=I/[Br]²[Br₂], were measured. These rate constants were found to depend on atom concentration and pressure and varied between kapp =5.4 x 10¹³ and 1.3 x 10¹⁵ cc²mole⁻² sec⁻¹. A mechanism of the emission reaction is discussed and it is suggested that as much as 15% of the total recombination of bromine atoms may be proceeding via excited states. In a similar study of the chlorine afterglow, all of the emission was attributed to the Cl₂ (³Π₀ +u —>¹Σ⁺g) transition. A study of the emission intensity in narrow bands revealed that I∝[CI]²•⁰±º•¹ at short wavelengths, corresponding to low vibrational levels of the ¹Π₀+u state, while I ∝ [Cl]¹•⁰±º‧¹ at long wavelengths and higher vibrational levels. Similarly, the pressure dependence of the intensity changed from I ∝ [Cl₂]⁰•⁵± º•² at long wavelengths to I ∝ [Cl₂]⁰•⁵±⁰•² at short wavelengths. Absolute emission intensity measurements were made in the region from 5000Å to 12000Å and the rate constants, defined by kapp = I/[Cl]²[Cl₂], were found. Extrapolation of these values of kapp to zero atom concentration yields kapp = 1.8 x 10¹⁴ cc² mole⁻² sec⁻¹. A mechanism for the formation and relaxation of the excited state is discussed. The study of absolute emission intensities was extended to measurements on excited oxygen molecules in a flow system. Observations on the 7619Å band of the O₂(¹Σ⁺g→³Σ⁻) transition yielded [0₂ (¹Σ⁺g)] = 1.77 x 10⁻⁹ moles 1.⁻¹, thereby confirming that this species is a minor constituent in the products of discharged oxygen. Absolute intensity studies on the 6340Å and 7030Å bands of the (0₂ (Δg))₂→(0₂(³Σ⁻))₂ transition indicate that the half life of the (O₂ (¹Δg))₂ collision complex is around 0.1 seconds. The emission spectrum produced when Cl₂ is reacted with H₂O₂ in solution was observed to originate in various transitions involving excited molecular oxygen. A yield of 0₂(¹Δg)of 10% from this reaction was estimated.

title: Three Essays on Big-Box Retailers and Regional Economics
Creators: name: Peralta, Denis
Publisher: name: Utah State University
Year: 2016

description: The big-box retail stores such as Wal-Mart and Target have become the focus of many studies researching their impacts on local economic outcomes. This dissertation studies three related topics: (i) the dynamic interrelationship among the presence of the big-box stores, retail wage, and employment, (ii) the impact of the big-box retailers on personal income growth, and (iii) the dynamic interrelationship between the presence of big-box retailers and personal income growth. The research draws important insights with potential implications for regional developers and policy makers.
The first essay analyzes the dynamic relationship among the presence of the big-box retailers, retail wage, and employment at the county level for 1986-2005. A vector autoregression model is applied on panel data. Impulse response functions and variance decompositions are also presented. Results suggest that the presence of big-box stores decreases retail wages and increases retail employment. Retail employment has a higher impact on the retailers’ location decision than retail wage. The results also show that the presence of Wal-Mart drives the above-mentioned effects, while the presence of Target is insignificant.
The second essay investigates the impact from the presence of big-box retailers on personal income growth in U.S. counties between 2000 and 2005 - based on neoclassical growth models of cross-country income convergence. Results suggest that counties having both Wal-Mart and Target stores experienced slower growth in personal income. After controlling for spatial autocorrelation, similar to the first essay, the effect of Wal-Mart’s presence on personal income growth is dominant in terms of statistical significance relative to Target’s.
The third essay expands the second essay and investigates the dynamic interaction between the presence of big-box retailers and personal income growth over time at the county level for the period 1987-2005, using a panel vector autoregression model. For this analysis, the earning shares of natural resources and manufacturing sectors are included - assuming that all the variables are endogenous to one another. The findings indicate that big-box retailers negatively affect personal income growth, which is consistent with the second essay. However, personal income growth has an insignificant effect on the big-box retailers’ location decision.
Using global invariant manifolds to understand metastability in Burgers equation with small viscosity

description: The large-time behavior of solutions to Burgers equation with small viscosity is described using invariant manifolds. In particular, a geometric explanation is provided for a phenomenon known as metastability, which in the present context means that solutions spend a very long time near the family of solutions known as diffusive N-waves before finally converging to a stable self-similar diffusion wave. More precisely, it is shown that in terms of similarity, or scaling, variables in an algebraically weighted $L^2$ space, the self-similar diffusion waves correspond to a one-dimensional global center manifold of stationary solutions. Through each of these fixed points there exists a one-dimensional, global, attractive, invariant manifold corresponding to the diffusive N-waves. Thus, metastability corresponds to a fast transient in which solutions approach this "metastable" manifold of diffusive N-waves, followed by a slow decay along this manifold, and, finally, convergence to the self-similar diffusion wave.

Рассматриваются основные вехи возникновения и истории праздника, содержание традиционных представлений ряженых и современный образ вильнюсских процессий. Шествия Трех королей возникли на религиозной основе, но хождение групп ряженых имеет и черты народной религиозности. В досоветское время в Вильнюсе ряженые действовали в контексте польской религиозной культуры, но были близки к литовской сельской традиции праздника Трех королей. В постсоветский период шествия по городу возродились как этнокультурный факт литовской городской обрядовой культуры и как символ завершения рождественского периода в жизни современного Вильнюса.

description: Undesirable and variable behavior in mares related to the estrous cycle is a common issue reported in the equine industry, especially for mares in a performance setting. These behaviors can interfere with, as well as decrease, overall performance. The objective of this study was to determine if administration of sixty units of oxytocin once daily for 29 days, regardless of when treatment was initiated during the estrous cycle, would induce prolonged corpus luteum (CL) function in cycling mares. Mares were randomly assigned to two groups: 1) saline-treated control (n=7) and 2) oxytocintreated (n=9). Control mares received 3 cc saline and oxytocin-treated mares received sixty units (3 cc) of oxytocin intramuscularly (IM) for 29 consecutive days. Treatment was initiated in all mares on the same day, independent of the day of the cycle. Jugular blood samples for determination of progesterone concentration were collected three times weekly (M, W, F) for 21 days before treatment was initiated. Beginning on the first day of treatment, blood samples were collected daily for seven days, three times weekly for the remainder of the treatment period, and then three times weekly for 45 days after the last treatment. Mares were considered to have prolonged CL function if serum progesterone remained >1.0 ng/mL for at least 30 days during/after the treatment period. The proportion of mares with prolonged CL function was higher in the oxytocin-treated group compared to the saline-treated group (7/9 vs. 1/7, respectively; P1.0 ng/mL throughout the treatment period and into the post-treatment period. All mares with prolonged CL function maintained elevated progesterone concentrations through at least day 56 of the study. Sixty units of exogenous oxytocin treatment for 29 consecutive days was effective in prolonging CL function as a means of estrus suppression in mares.

description: В настоящее время происходит переосмысление места и роли фольклора в социально-культурной сфере, активно обсуждаются вопросы его теоретических и практических аспектов, осуществляется поиск механизмов конструирования и организации обрядовых практик. В статье рассматриваются вопросы адаптации традиционной культуры. Особое внимание автор уделил изучению семейной обрядности, в частности ритуальных практик, связанных с проводами на военную службу. Несмотря на изменения и сильное разрушение традиционного хода рекрутских обрядов, многие ритуалы фиксируются на Орловской территории области и сегодня. Безусловно, невозможно возродить к жизни народные традиции, бытовавшие на Руси в старину, но на основе изучения значительного массива источников, применяя социально-культурные технологии, можно пробудить интерес к их познанию и сохранению, обратить особое внимание на глубинное и смысловое их значение.

description: The greater sage-grouse (Centrocercus urophasianus; sage-grouse) has been a species of conservation concern since the early 20th century due to range-wide population declines. To contribute to knowledge of the ecology of sage-grouse populations that inhabit the Box Elder Sage Grouse Management Area (SGMA) in northwestern Utah and quantify their responses to landscape scale habitat manipulations, I monitored vital rates and habitat selection of 45 female sage-grouse from 2014 to 2015. Using telemetry locations of female sage-grouse with known nest and brood fates, I created Generalized Linear Mixed Models to estimate the influence of proximity to pinyon (Pinus spp.) and juniper (Juniperus spp.; conifer) encroachment, and removal projects may have on sagegrouse reproductive fitness in the Box Elder SGMA. The best fit model suggested that for every 1 km a nest was located away from a conifer removal area, probability of nest success was reduced by 9.1% (β = -0.096, P < 0.05). Similarly, for every 1 unit increase in the log-odds of selection for distance to treatment, probability of brood success declined by 52.6% (P = 0.09). The probability of brood success declined by 77.2% (P < 0.05) as selection for conifer canopy cover increased.
To evaluate sage-grouse habitat use, I used fecal pellet surveys to estimate relative pellet density in conifer encroachment, removal, and undisturbed sagebrush areas. Sage-grouse pellet densities were estimated at 4.6 pellets/ha (95% CI = 1.2, 10.9), 8.6 pellets/ha (95% CI = 3.8, 15.2), and 50.6 pellets/ha (95% CI = 36.8, 69.6), in conifer encroachment, removal, and undisturbed sagebrush areas respectively. Density estimates did not statistically differ between conifer encroachment and removal areas.
To determine if vegetation micro-site characteristics at sage-grouse use sites influenced nest or brood fate, I recorded standard vegetation measurements for all radio-marked sage-grouse nests and a stratified random sample of brood-use sites from 2014- 2015 and compared them to random sites. Micro-site vegetation characteristics measured did not differ for successful and unsuccessful nests. Many characteristics differed between micro-sites used by successful broods and those used by unsuccessful broods. Sites used by successful broods also differed from random sites.

description: We describe the scaling limit of the nearest neighbour prudent walk on the square lattice, which performs steps uniformly in directions in which it does not see sites already visited. We show that the scaling limit is given by the process Z(u) = s_1 theta^+(3u/7) e_1 + s_2 theta^-(3u/7) e_2, where e_1, e_2 is the canonical basis, theta^+(t), resp. theta^-(t), is the time spent by a one-dimensional Brownian motion above, resp. below, 0 up to time t, and s_1, s_2 are two random signs. In particular, the asymptotic speed of the walk is well-defined in the L^1-norm and equals 3/7.

description: We consider the application of quantum corrections computed using renormalization group arguments in the astrophysical domain and show that, for the most natural interpretation of the renormalization group scale parameter, a gravitational coupling parameter $G$ varying $10^{-7}$ of its value across a galaxy (which is roughly a variation of $10^{-12}$ per light-year) is sufficient to generate galaxy rotation curves in agreement with the observations. The quality of the resulting fit is similar to the Isothermal profile quality once both the shape of the rotation curve and the mass-to-light ratios are considered for evaluation. In order to perform the analysis, we use recent high quality data from nine regular disk galaxies. For the sake of comparison, the same set of data is modeled also for the Modified Newtonian Dynamics (MOND) and for the recently proposed Scalar Tensor Vector Gravity (STVG). At face value, the model based on quantum corrections clearly leads to better fits than these two alternative theories.

идентичности

description: На основе собранных автором более 50 солдатских блокнотов и альбомов 1970–2000-х годов в статье рассматриваются конкретные феномены армейского хенд-мейда как процесс и результат сотворения их создателями новой идентичности. Идентичность эта выстраивается путем: 1) противопоставления «мы — они»; 2) усвоения базовых понятий и принципов поведения, характерных для своей категории служащих. Она имеет несколько уровней и стадий. Взяв в качестве базового блокнот матроса-подводника, можно констатировать следующие уровни идентификации в связи с осмысляемыми составителем блокнота оппозициями: военные — штатские; матросы — гражданские; карась — годок — и другие противопоставления на основе определения статуса военного согласно сроку службы внутри своей субкультурной группы; матросы — солдаты (все остальные военнослужащие); подводники — остальные моряки. Человек всегда существует не в одном измерении и является носителем не одной идентичности, а целого их «букета». Анализ приведенных текстов (которые впервые вводятся в научный оборот) показывает, что все эти идентичности (военный, моряк, подводник, дух, карась, годок, гражданский) формировались параллельно уже в первый год службы (хотя каждая — в разной степени, некоторые — латентно, особенно статусные идентичности) и блокнот, закрепляя на письме базовые понятия и ценности, стереотипные представления определенной субкультурной группы, в которой оказался составитель данного документа, стал «материализованной памятью» о сложном мире сознания солдат-срочников, с его «притяжениями» и «отталкиваниями», контрастами и поиском гармонии в дисгармоничном мире армейской службы.

description: Статья посвящена частушкам о лесозаготовках, записанным во время японско-русских фольклорных экспедиций в Верхнетоемский район Архангельской области в 1995–2015 гг. Такие частушки, как «На базе, на базе, / На базе на лесу / Всё лицо мое сгорело, / Потеряла всю красу» были записаны от бывших колхозников, которые родились в 1910–1920-х гг., а работали зимой в далеком от дома лесу в 1930–1940-х гг. Информанты подробно рассказывали, как они жили на лесобазе в бараках, тяжко работали, мерзли и голодали. Бывший председатель колхоза рассказал о системе трудодней и о том, как местные жители старались не попасть на лесозаготовки. В то же время для молодежи это был коммуникативный опыт, новые знакомства, общение, пляски, сочинение и пение частушек. Понять частушки о лесозаготовках можно только на фоне знаний об истории и жизни 1930–1940-х гг. Материалы японско-русских экспедиций сейчас обрабатываются для создания цифрового архива и мультимедийного издания, чтобы пользователи могли получить полноценное представление о разных жанрах местной фольклорной традиции.
Orbital Ordering and Unfrustrated $(π,0)$ Magnetism from Degenerate Double Exchange in the Iron Pnictides

description: The magnetic excitations of the iron pnictides are explained within a degenerate double-exchange model. The local-moment spins are coupled by superexchanges $J_1$ and $J_2$ between nearest and next-nearest neighbors, respectively, and interact with the itinerant electrons of the degenerate $d_{xz}$ and $d_{yz}$ orbitals via a ferromagnetic Hund exchange. The latter stabilizes $(π,0)$ stripe antiferromagnetism due to emergent ferro-orbital order and the resulting kinetic energy gain by hopping preferably along the ferromagnetic spin direction. Taking the quantum nature of the spins into account, we calculate the magnetic excitation spectra in the presence of both, super- and double-exchange. A dramatic increase of the spin-wave energies at the competing Néel ordering wave vector is found, in agreement with recent neutron scattering data. The spectra are fitted to a spin-only model with a strong spatial anisotropy and additional longer ranged couplings along the ferromagnetic chains. Over a realistic parameter range, the effective couplings along the chains are negative corresponding to unfrustrated stripe antiferromagnetism.

Year: 2019

description: While diagnostic solutions for an aircraft Auxiliary Power Unit (APU) turbine system have reached relatively high level of maturity, accurate prediction of Remaining Useful Life (RUL) remains a challenging task. This is mainly due to the high complexity of the system, limited number of measured variables and significant diversion of operating conditions. This paper deals with a hybrid approach to APU Prognostic Health Monitoring (PHM) system development employing both, a physics-based model of APU system available to Honeywell as the engine manufacturer and historical data from APUs operations and repair shop visits. Two different Condition Indicators (CIs), the model-based and the data-driven, are developed to estimate the level of degradation of APU core section. The CIs are fed into binary classification algorithm which is used to distinguish if the RUL of an asset is lower than a defined threshold; this representation of Prognostic Indicator (PI) can be deemed as a maintenance recommendation flag provided to APU operator to schedule a maintenance action.

description: In this paper we study a novel superconductor-ferromagnet-superconductor (SC-FM-SC) Josephson junction array deposited on top of a two-dimensional quantum spin Hall (QSH) insulator. The existence of Majorana bound states at the interface between SC and FM gives rise to charge-e tunneling, in addition to the usual charge-2e Cooper pair tunneling, between neighboring superconductor islands. Moreover, because Majorana fermions encode the information of charge number parity, an exact Z_2 gauge structure naturally emerges and leads to many new insulating phases, including a deconfined phase where electrons fractionalize into charge-e bosons and topological defects. A new superconductor-insulator transition has also been found.
