112th Annual Exhibition June 4 - June 29, 2001, National Association of Women Artists (1889-2001)
Creators: name: No Name Supplied
Publisher: name: No Publisher Supplied
Year: 2001

description: The National Association of Women Artists (NAWA) was established in 1889 and is the oldest professional women's fine arts organization in the United States. NAWA's mission is to promote awareness of, and interest in, visual art created by women in the United States. As part of this effort NAWA holds an annual exhibition of works by members of the association and publishes an exhibition catalog to accompany or commemorate the annual exhibitions. These catalogs not only function as an exhibition catalog, but also as a document that summarizes the structure, membership, and activities of the association.Information that can be found in these catalogs includes lists of officers, members of the executive board and committees, prize winners, lists of exhibitor and members, and images of some of the artwork exhibited. Catalogs from the 2000s also include information on NAWA events and activities beyond the annual exhibition.Please note that the numbering of the annual catalogs was adjusted in 1960 and again in 1971. For example, NAWA designated the annual exhibition in 1960 as the 70th Anniversary Exhibition after 1959 was the 67th Annual Exhibition. These adjustments appear to have been made to reflect the date of the founding of the association, so that, by 1989, the annual exhibition commemorated the 100-year anniversary of the founding of NAWA in 1889.

description: Proton activity, which is usually expressed as a pH value, is among the most important properties in the design of chemical and biochemical processes as it determines the dissociation of species in aqueous mixtures. This article addresses the prediction of pH values in multiphase systems based on the IUPAC definition via proton activity. The required proton activity coefficients were predicted using the thermodynamic equation of state ePC-SAFT advanced. The developed framework considers reaction equilibria and phase equilibria (vapor–liquid and liquid–liquid) to predict pH in the equilibrated liquid phases.

Creators: name: Ding, Jiayi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Bitcoin arises recent years as a most successful and widely used cryptocurrency. Though it was first invented as a decentralized currency, Bitcoin has become more and more popular as a financial asset with a market capitalization of around $117 billion, as increasing number of investors and portfolio managers start to invest in and trade it. In this paper, we are interested in finding out the future course of Bitcoin prices and returns and examining the predictive power of the ARMA- GARCH model. The paper uses Python and R environment to analyze and model financial time series. The first part covers the preliminary analysis of the daily closing prices and returns of Bitcoin, and also the stationarity of the return series. The second part intends to fit an appropriate ARMA-GARCH model. The last part focuses on using fitted model to predict future returns and prices of Bitcoin and compare it to our validation dataset.

description: A rotating thin shell in a (2+1)-dimensional asymptotically AdS spacetime is studied. The spacetime exterior to the shell is the rotating BTZ spacetime and the interior is the empty spacetime with a cosmological constant. Through the Einstein equation in (2+1)-dimensions and the corresponding junction conditions we calculate the dynamical relevant quantities, namely, the rest energy-density, the pressure, and the angular momentum flux density. We also analyze the matter in a frame where its energy-momentum tensor has a perfect fluid form. In addition, we show that Machian effects, such as the dragging of inertial frames, also occur in rotating (2+1)-dimensional spacetimes. The weak and the dominant energy condition for these shells are discussed.

Fractal Fluctuations in Human Walking: Comparison between Auditory and Visually Guided Stepping
Creators: name: Terrier, Philippe
Publisher: name: arXiv
Year: 2015
Subjects: subject: Neurons and Cognition (q-bio.NC)
subject: FOS: Biological sciences

description: In human locomotion, sensorimotor synchronization of gait consists of the coordination of stepping with rhythmic auditory cues (auditory cueing, AC). AC changes the long-range correlations among consecutive strides (fractal dynamics) into anti-correlations. Visual cueing (VC) is the alignment of step lengths with marks on the floor. The effects of VC on the fluctuation structure of walking have not been investigated. Therefore, the objective was to compare the effects of AC and VC on the fluctuation pattern of basic spatiotemporal gait parameters. Thirty-six healthy individuals walked 3 x 500 strides on an instrumented treadmill with augmented reality capabilities. The conditions were no cueing (NC), AC, and VC. AC included an isochronous metronome. In VC, projected stepping stones were synchronized with the treadmill speed. Detrended fluctuation analysis assessed the correlation structure. The coefficient of variation (CV) was also assessed. The results showed that AC and VC similarly induced a strong anti-correlated pattern in the gait parameters. The CVs were similar between the NC and AC conditions but substantially higher in the VC condition. AC and VC probably mobilize similar motor control pathways and can be used alternatively in gait rehabilitation. However, the increased gait variability induced by VC should be considered.

description: Feed scarcity is a major challenge facing free-range beef farming in semi-arid areas. Specifically, low quality and quantity of forage in rangelands and higher feeding costs are the main constraints limiting smallholder free-range beef farmers’ participation in mainstream beef markets. Using farmers’ participatory approaches, this study identified major locally available forage resources (LAFRs) and evaluated their nutritional value. A total of 40 free-ranging commercially orientated smallholder beef farmers were interviewed using semi-structured questionnaires and tasked to identify LAFRs in the Cradock and Middelburg areas of the Eastern Cape, South Africa. Chemical analysis was conducted for the most cited forages such as African sheepbush (Pentzia incana), sweet thorn (Vachellia karroo) leaves and pods, reed (Phragmites australis), lucerne (Medicago sativa) hay, natural pasture grasses (NPGs) and barbary fig, or prickly pear cactus, (Opuntia ficus-indica) cladodes collected from twelve participants’ farms. Feed shortage was ranked by more than 53% respondents as the main constraint to smallholder beef production. Regardless of the farming area, crude protein content of V. karroo leaves and pods averaging 18.8 and 19.5%, respectively, was higher than other LAFRs. However, V. karoo pods had relatively low ash content than other forages in both farming areas. Opuntia ficus-indica attained high in vitro neutral detergent fibre digestibility at 12, 24 and 48 hr incubation periods, due to low neutral detergent fibre, acid detergent fibre and acid detergent lignin. Integration of participatory inventory and chemical analysis proved to be reliable in identifying LAFRs, with V. karroo leaves and O. ficus-indica cladodes being the main potential forage resources for inclusion in beef cattle diets. Further research is recommended to substantiate their supplementary nutritive value and level of inclusion in beef cattle finishing diets.

 Lectotype (designated here): — COLOMBIA. Tolima, El Fresno, Cuchilla del Topacio, 3 December 1939, García-Barriga 8222 (COL-13435!; isolectotypes: COL-407610! NY!, US!).
 Nomenclatural notes:— The protologue indicates that the holotype of F. fresnoensis was deposited in the herbarium COL; however, there are two preparations from a single gathering (Pérez-Arbeláez 10221) there. There is no clear indication on the label whether these two preparations are parts of the same specimen (Turland et al. 2018, Art. 8.3); therefore, these are considered to be duplicates. Therefore, we designate here García-Barriga 8222 (COL-13435) as the lectotype because it has branches, leaves, syconia, and stipules.
 Taxonomical notes:— The currently accepted name for this taxon remain uncertain, Berg (2007) has doubt if it is Ficus americana subsp. andicola.

The Physicist's Companion to Current Fluctuations: One-Dimensional Bulk-Driven Lattice Gases

description: One of the main features of statistical systems out of equilibrium is the currents they exhibit in their stationary state: microscopic currents of probability between configurations, which translate into macroscopic currents of mass, charge, etc. Understanding the general behaviour of these currents is an important step towards building a universal framework for non-equilibrium steady states akin to the Gibbs-Boltzmann distribution for equilibrium systems. In this review, we consider one-dimensional bulk-driven particle gases, and in particular the asymmetric simple exclusion process (ASEP) with open boundaries, which is one of the most popular models of one-dimensional transport. We focus, in particular, on the current of particles flowing through the system in its steady state, and on its fluctuations. We show how one can obtain the complete statistics of that current, through its large deviation function, by combining results from various methods: exact calculation of the cumulants of the current, using the integrability of the model ; direct diagonalisation of a biased process in the limits of very high or low current ; hydrodynamic description of the model in the continuous limit using the macroscopic fluctuation theory (MFT). We give a pedagogical account of these techniques, starting with a quick introduction to the necessary mathematical tools, as well as a short overview of the existing works relating to the ASEP. We conclude by drawing the complete dynamical phase diagram of the current. We also remark on a few possible generalisations of these results.

description: The persistent spread of shrublands is a global phenomenon observed across semiarid grassland-shrubland boundaries. Observations in South Africa, however, have detected a contrasting trend of increasing grass cover across the transition between the Nama-Karoo and Grassland Biomes over the last few decades. A west-to-east gradient of increasing mean annual rainfall, and underlying geology, controls the natural transition of Karoo dwarf shrublands to semiarid grasslands. The availability of historical vegetation surveys and landscape photographs, weather, and livestock census records, made it possible to assess the nature, extent, and drivers of vegetation change across this biome transition. Rainfall has been generally higher over the last four decades compared to the years prior to the original surveys. This, together with a reduction in livestock numbers, is the main driver of the westward expansion by ∼100 km of perennial grasses, and a general increase in dwarf shrub and total vegetation cover. Rangeland condition, as indexed by estimates of grazing capacity, has improved significantly. Despite a structural shift towards grassland-dominance, the original species complement has persisted. The rainfall-driven increase in grass fuel loads in the region, however, places these rangelands at risk of becoming altered by increasing fire frequency.
Comparison of Antibiotic-Resistant Staphylococcus Aureus among Industrial Hog Operation Worker Households and Community Referent Households in North Carolina
Creators: name: Jiang, Sharon

description: Carriage of livestock-associated Staphylococcus aureus has been reported among
industrial hog operation workers in North Carolina, and these bacteria may be more likely to be antibiotic-resistant than hospital-associated or community-associated S. aureus. This study used antibiotic susceptibility testing to determine whether livestock workers and their households are at greater risk of carrying antibiotic-resistant S. aureus than other non-exposed members of the community. Kirby-Bauer disk diffusion assays were performed on S. aureus from 167 industrial hog operation household members, including 104 adults and 63 children, and 159 non-exposed community, or community referent, household members, including 97 adults and 62 children. The prevalence of multidrug-resistant S. aureus from industrial hog operation children was 1.9 that of industrial hog operation adults and 1.7 that of community referent children (95%CI [1.3,
2.9], p=0.001; 95% CI [1.1, 2.7], p=0.02). Methicillin-resistant S. aureus (MRSA) prevalence in industrial hog operation children was 5.1 that of adults from the same group (95% CI [1.8, 14], p=0.0006). The prevalence of tetracycline-resistant S. aureus from industrial hog operation adults was 4.3 that of children from the same group (95% CI [1.5,12], p=0.003). These results demonstrate more significant differences in antibiotic-resistant S. aureus within industrial hog operations households rather than between the two household groups. Additional research is needed to determine if these strains pose a health risk to workers, their children and the broader community.
A Lucky Imaging search for stellar sources near 74 transit hosts

description: Many transiting planet host stars lack high resolution imaging and thus close stellar sources can be missed. Those unknown stars potentially bias the derivation of the planetary and stellar parameters from the transit light curve, no matter if they are bound or not. In addition, bound stellar companions interact gravitationally with the exoplanet host star, the disk and the planets and can thus influence the formation and evolution of the planetary system strongly. We extended our high-resolution Lucky Imaging survey for close stellar sources by 74 transiting planet host stars. 39 of these stars lack previous high-resolution imaging, 23 are follow up observations of companions or companion candidates, and the remaining stars have been observed by others with AO imaging though in different bands. We determine the separation of all new and known companion candidates and estimate the flux ratio in the observed bands. All observations were carried out with the Lucky Imaging camera AstraLux Norte at the Calar Alto 2.2 m telescope in i' and z' passbands. We find new stellar sources within 1 arcsec to HAT-P-27, HAT-P-28, HAT-P-35, WASP-76, and WASP-103, and between 1 and 4 arcsec to HAT-P-29 and WASP-56.

"A British Lake": Kuwait and the 1913 Anglo-Ottoman Convention
Creators: name: Tyler, Ethan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: The 1913 Anglo-Ottoman Convention is remembered mostly for its direct political effects in Kuwait by solidifying Kuwaiti autonomy and the international rights of Britain in Kuwait. However, this agreement contains many provisions on trade, international boundaries, oil concessions, and the Baghdad Railway that solidify the wider British strategic interests at the time. British involvement in the Persian Gulf was not recent or limited to Kuwait. The British
Persian Gulf Residency based in Bushire along the coast of modern day Iran was the hub of British activity in the Persian Gulf for most diplomatic, economic, and military affairs under the British Indian Government (hereafter referred to as the British Raj). From the 1700’s onward, British naval presence in the Gulf continuously grew through the form of protecting trade and safeguarding the burgeoning East India Company’s colonial holdings. However, Britain took no serious diplomatic or economic interest in the Persian Gulf until the mid-1800’s, growing rapidly in the 1880’s and 1890’s into the turn of the century. This interest was formed by crafting various treaties with local rulers to establish certain rules for British economic activity and hold that these rules would be enforced. These treaties mostly took the form of controlling piracy and allowing port access with polities such as the Trucial States, Bahrain, and Muscat. I argue that the 1913 Convention, happening on the eve of the outbreak of war, was the culmination of British policy in the Gulf which centered on British economic and political gain by working to create a status quo which supported the British system of imperial management. Early commercial and political treaties within the Gulf dealt with access to and security of India. After the of succession of Mubarak al-Sabah as Sheikh of Kuwait in 1896, British actions within the Gulf centering on Kuwait were made to keep Kuwait autonomous within the Ottoman Empire. British support of Mubarak defended Kuwait from the Ottomans and the Ottoman-backed Emirate of Ha’il, eventually establishing autonomy. The British upheld imperial infrastructure as manifestations of political strategy in securing British strategic and economic interests in the Gulf while defending these interests against perceived threats from the Germans or Ottomans in the form of the Baghdad Railway. The 1913 Anglo-Ottoman Convention was the culmination of the British status quo and secured British interests. The formation of the Persian
Gulf as a “British lake” within the Residency’s view came from negotiated imperial development coupled with the political patronage of Kuwait and other local powers.

description: Improving constraints on the abundance of basaltic asteroids in the main asteroid belt is necessary for better understanding the thermal and collisional environment in the early solar system, for more rigorously identifying the genetic family for (4) Vesta, for determining the effectiveness of Yarkovsky/YORP in dispersing asteroid families, and for better quantifying the population of basaltic asteroids in the outer main belt (a greater than 2.5 AU) that are likely unrelated to (4) Vesta. NIR spectral observations in this work were obtained for the Vp-type asteroids (2011) Veteraniya, (5875) Kuga, (8149) Ruff, (9147) Kourakuen, (9553) Colas, (15237) 1988 RL6, (31414) Rotaryusa, and (32940) 1995 UW4 during August and September 2014 utilizing the SpeX spectrograph at the NASA Infrared Telescope Facility (IRTF), Mauna Kea, Hawaii. Spectral band parameter (band centers, Band Area Ratios) and mineralogical analysis (pyroxene chemistry) for each average asteroid NIR reflectance spectrum suggests a howardite-eucrite-diogenite (HED) meteorite analog for each asteroid. (5875) Kuga is most closely associated with the eucrite meteorites, (31414) Rotaryusa is most closely associated with the diogenites, and the remaining other six asteroids are most closely associated with the howardite meteorites. Along with orbital locations in the inner main belt and in the vicinity of (4) Vesta, the existing evidence suggests that these eight Vp-type asteroids are also likely Vestoids.

description: Singular spectrum analysis (SSA) is considered for decomposition of time series into identifiable components. The Basic SSA method is nonparametric and constructs an adaptive expansion based on singular value decomposition. The investigated modification is able to take into consideration a structure given in advance and therefore can be called semi-nonparametric. The approach called SSA with projection includes preliminary projections of rows and columns of the series trajectory matrix to given subspaces. One application of SSA with projection is the extraction of polynomial trends, e.g., a linear trend. It is shown that SSA with projection can extract polynomial trends much better than Basic SSA, especially for linear trends. Numerical examples including comparison with the least-square approach to polynomial regression are presented.

description: The Mesozoic-Cenozoic geological evolution of the southern Great Xing’an Range (GXR) has long been controversial since it is located in the superposed region of different tectonic regimes and involves complex interactions. Here, we present low-temperature thermochronological data from granitoids emplaced in multiple magmatic stages to delineate the tectono-thermal history and further understand the geodynamic process. Most zircon and apatite (U-Th)/He ages, within error, indicate Early Cretaceous: the zircon average (U-Th)/He ages range from 146.7 ± 8.7 to 120.0 ± 7.1 Ma, except for the oldest data (162.5 ± 9.6 Ma) and the apatite (U-Th)/He ages vary from 138.7 ± 8.2 to 94.8 ± 7.5 Ma, except for the youngest age (70.8 ± 4.3 Ma). Systematic numerical modelling reveals that a rapid cooling and exhumation process with rates of 2.5-10 oC/Ma and 0.07-0.29 mm/yr occurred in the southern GXR during the early Cretaceous (145–110 Ma). We propose that the rapid uplift and exhumation of intrusive rocks during the early Cretaceous is also a manifestation of the extensional regime in the southern GXR, which is dominated by the rollback of the subducted Paleo-Pacific oceanic plate superposed by the post-orogenic extensional collapse of the Mongol-Okhotsk belt. In addition, the slow exhumation process since the late Cretaceous (~0.01 mm/yr) suggests that the Paleo-Pacific Ocean tectonic regime has a weak impact on the southern GXR area.

 Nomenclatural notes:— The protologue does not cite the collector; however, there is mention of “Richard II”, which is probably the herbarium where the type was located. Berg & Villavicencio (2004) cited the collection of De la Sagra s.n. at P as the type; however, this cannot be considered a lectotypification because it occurred after 2001 and “designated here” or similar phrase was not used (Turland et al. 2018, Art. 7.11). Of the two existing collections in Paris, we have designated P-00756598 as the lectotype because it has syconia in the branches.

description: O Plano de Desenvolvimento da Unidade (P.D.U.) é o principal instrumento de descentralização do planejamento universitário. Planejar uma instituição complexa não deve ser tarefa para um pequeno grupo de pessoas fechadas numa sala. A existência de PDUs permite que as decisões que interferem no futuro da Universidade sejam tomadas com ampla participação de seus professores, estudantes e técnicos-administrativos. Isso significa que as pessoas podem e devem expressar no PDU o que desejam para o futuro próximo, estabelecendo metas de curto prazo, e indicando o que cada um e cada uma precisa fazer para que essas metas sejam alcançadas. Por meio do PDU, os problemas são identificados por quem mais é afetado por eles, estabelecendo prioridades, escolhendo indicadores e meios de avaliação. Isso deve fazer surgir na UFPel uma nova cultura de planejamento, descentralizada e socialmente referenciada. A elaboração do PDU é uma importante oportunidade de reflexão sobre a relação da Unidade com o restante da Universidade e com toda a Sociedade. Ele permite apresentar, avaliar e debater a situação atual, revendo e propondo inserções e compromissos sociais para os próximos dois anos, ou quatro semestres letivos.

description: The CMS experiment at the Large Hadron Collider has reported a 2.8$σ$ excess in the $(2e)(2jets)$ channel around 2.1 TeV. Interpretation of this data is reconsidered in terms of the production of a right-handed weak gauge boson, $W_R$, of the left-right symmetric model and in an $SO(10)$ grand unified theory abiding by the Extended Survival Hypothesis. The left-right symmetric model can be consistent with this excess if (a) the heavy right-handed neutrino has a mass near $W_R$, or (b) if $g_L \neq g_R$, or (c) the right-handed CKM matrix is nontrivial. Combinations of the above possibilities are also viable. A $W_R$ with a mass in the TeV region if embedded in $SO(10)$ is not compatible with $g_L = g_R$. Rather, it implies $0.64 \leq g_R/g_L \leq 0.78$. Further, a unique symmetry-breaking route -- the order being left-right discrete symmetry breaking first, followed by $SU(4)_C$ and finally $SU(2)_R$ -- to the standard model is picked out. The $L \leftrightarrow R$ discrete symmetry has to be broken at around $10^{16}$ GeV. The grand unification scale is pushed to $10^{18}$ GeV making the detection of proton decay in ongoing searches rather unlikely. The $SU(4)_C$ breaking scale can be at its allowed lower limit of $10^6$ GeV so that $n - \bar{n}$ oscillation or flavour changing processes such as $K_L \rightarrow μe$ and $B_{d,s} \rightarrow μe$ may be detectable. The Higgs scalar multiplets responsible for $SO(10)$ symmetry breaking at various stages are uniquely identified so long as one adheres to a minimalist principle. We also remark, {\em en passant}, about a partially unified Pati-Salam model.

description: The Mesozoic-Cenozoic geological evolution of the southern Great Xing’an Range (GXR) has long been controversial since it is located in the superposed region of different tectonic regimes and involves complex interactions. Here, we present low-temperature thermochronological data from granitoids emplaced in multiple magmatic stages to delineate the tectono-thermal history and further understand the geodynamic process. Most zircon and apatite (U-Th)/He ages, within error, indicate Early Cretaceous: the zircon average (U-Th)/He ages range from 146.7 ± 8.7 to 120.0 ± 7.1 Ma, except for the oldest data (162.5 ± 9.6 Ma) and the apatite (U-Th)/He ages vary from 138.7 ± 8.2 to 94.8 ± 7.5 Ma, except for the youngest age (70.8 ± 4.3 Ma). Systematic numerical modelling reveals that a rapid cooling and exhumation process with rates of 2.5-10 oC/Ma and 0.07-0.29 mm/yr occurred in the southern GXR during the early Cretaceous (145–110 Ma). We propose that the rapid uplift and exhumation of intrusive rocks during the early Cretaceous is also a manifestation of the extensional regime in the southern GXR, which is dominated by the rollback of the subducted Paleo-Pacific oceanic plate superposed by the post-orogenic extensional collapse of the Mongol-Okhotsk belt. In addition, the slow exhumation process since the late Cretaceous (~0.01 mm/yr) suggests that the Paleo-Pacific Ocean tectonic regime has a weak impact on the southern GXR area.

description: It is shown that rapidly-rotating Kerr black holes are characterized by the dimensionless ratio $τ_{\text{gap}}/τ_{\text{emission}}=O(1)$, where $τ_{\text{gap}}$ is the average time gap between the emission of successive Hawking quanta and $τ_{\text{emission}}$ is the characteristic timescale required for an individual Hawking quantum to be emitted from the black hole. This relation implies that the Hawking cascade from rapidly-rotating black holes has an almost continuous character. Our results correct some inaccurate claims that recently appeared in the literature regarding the nature of the Hawking black-hole evaporation process.

Design Rules for Discovering 2D Materials from 3D Crystals
Creators: name: Brightbill, Eleanor Lyons
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Two-dimensional (2D) materials are championed as potential components for novel technologies due to the extreme change in properties that often accompanies a transition from the bulk to a quantum-confined state. While the incredible properties of existing 2D materials have been investigated for numerous applications, the current library of stable 2D materials is limited to a relatively small number of material systems, and attempts to identify novel 2D materials have found only a small subset of potential 2D material precursors. Here I present a rigorous, yet simple, set of criteria to identify 3D crystals that may be exfoliated into stable 2D sheets and apply these criteria to a database of naturally occurring layered minerals. These design rules harness two fundamental properties of crystals—Mohs hardness and melting point—to enable a rapid and effective approach to identify candidates for exfoliation. It is shown that, in layered systems, Mohs hardness is a predictor of inter-layer (out-of-plane) bond strength while melting point is a measure of intra-layer (in-plane) bond strength. This concept is demonstrated by using liquid exfoliation to produce novel 2D materials from layered minerals that have a Mohs hardness less than 3, with relative success of exfoliation (such as yield and flake size) dependent on melting point.

 Lectotype (designated here): — VENEZUELA. Mérida, alrededores de Tabay, 17 October 1930, W.Gehriger 450 (VEN!; isolectotypes: G!, PH! US!).
 Nomenclatural notes:— The protologue does not state the name of the herbarium where the type of F. maitin was deposited. Berg (2007b) cited the specimen Gehriger 450 (VEN) as the holotype; however, this cannot be considered a lectotypification because it was published after 2001 and “designated here” or similar phrase was not used (Turland et al. 2018, Art. 7.11). Here, we designate Gehriger 450 (VEN) as lectotype because it contains a well-preserved branch with leaves, syconia, and stipules.
 Taxonomical notes:— The currently accepted name for this taxon is Ficus americana subsp. andicola.

Functional Redundancy and Feedback Regulation between Canonical Histone H3 and Variant Histone H3.3 in Drosophila
Creators: name: Kwon, Esther

Year: 2019

description: Animal cell chromatin contains two types of histones: canonical and variant. Although canonical and variant histones have similar structures, their expression and incorporation into chromatin are regulated differently. Consequently, the extent of their overlap in genome functions like transcription is not completely understood. Canonical histones are expressed and incorporated into chromatin only during S phase of the cell cycle, whereas variant histones are expressed and incorporated into chromatin throughout the cell cycle. Drosophila melanogaster has a single locus with ~100 copies of each of the five canonical histone genes (H1, H2a, H2b, H3, and H4).  In Drosophila, variant histone H3.3 is encoded by two genes, H3.3A and H3.3B, which produce identical protein products. Importantly, these H3.3 genes are not located within the canonical histone gene cluster. Both canonical histone H3 and variant histone H3.3 are highly conserved across eukaryotes. To understand H3.3 gene function, we developed a genetic platform involving rescue of a deletion of the endogenous canonical histone locus by a transgene containing 12 copies of each canonical histone gene (12xHWT; Histone Wild Type). The viability of 12xHWT flies is a surprise because diploid fly cells normally have 200 canonical histone gene copies, including H3. Therefore, we hypothesized that H3.3 compensates for H3 in the 12xHWT background despite the two histone proteins being deposited in different but overlapping genomic regions. We found that 12xHWT animals are inviable after the mutation of both H3.3A and H3.3B, indicating that H3.3 genes can functionally compensate for reduced canonical H3 gene copy number. Furthermore, we found that total H3.3 protein levels in chromatin are higher in 12xHWT animals compared to wild type, indicating that H3.3 protein upregulation likely compensates for reduced canonical H3 histone protein. Our research furthers our understanding of the functional overlap between canonical and variant histones, and provides insights into the functional interplay between H3.3 and H3 in a developing organism.
Can you be persuaded to eat healthier?

description: This study aims to develop and explain the findings we got from our first study in this research line, which suggested that self-persuasion works better for Dutch people for promoting their healthy eating intention; while direct persuasion works better for Moroccans. This study is twofold. First it aims to replicate the result from study 1 and second, to examine whether collective independence self-construal and power distance are the cultural moderators which moderate the relationship between persuasion and eating behavior.

description: Eu modified Na1/2Bi1/2TiO3 (NBT) was investigated for electric-field induced Eu+3 photoluminescence (PL) and structural changes. Detailed analysis revealed that below a critical Eu composition electric field irreversibly suppresses the structural heterogeneity inherent of the host matrix NBT and brings about a long range ferroelectric state with rhombohedral (R3c) distortion. PL study revealed that structural disorder on the nano-scale opens new channels of radiative transitions which can be suppressed by electric field. This study suggests that Eu+3 luminescence can be used to probe the relative degree of field induced structural ordering in relaxor ferroelectrics and also in high performance piezoelectric alloys where electric field couples very strongly with the lattice and structural degrees of freedom.

description: By relating the functional averages of a generic scalar operator in simulations with Open (O) and Periodic (P) boundary conditions (BCs) respectively for $SU(3)$ lattice gauge theory, we show that the scalar glueball mass and the glueball to vacuum matrix element can be extracted very efficiently from the former. Numerical results are compared with those extracted from the two point function of the time slice energy density (both PBC and OBC). The scaling properties of the mass and the matrix element are studied with the help of Wilson (gradient) flow.

Gender and Bipartisan Cosponsorship: Evidence from the United States House of Representatives
Creators: name: Mason, Cassandra
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The goal of this study is to assess how the increase in female legislators in the U.S. House of Representatives has related to the percentage of bipartisan cosponsors on House bills. Answering this question could provide key insight into the benefits of increasing female representation, which would strengthen the argument for electing women to office. Previous literature on the topic suggests that there are differences between male and female representatives regarding both legislative behavior and predisposition towards collaboration. Further, scholarship suggests that the Democratic and Republican party leadership differ in their tolerance of collaborative behavior amongst female representatives. I find that there is not a strong relationship between female representatives and overall bipartisan collaboration that does not take party into account. However, there is evidence that Democratic female representatives might be driving Democratic bipartisan cosponsorship under certain conditions. Overall, this study finds that gender matters for bipartisan cosponsorship, but partisanship matters more.

description: Systems of free fermions are classified by symmetry, space dimensionality, and topological properties described by K-homology. Those systems belonging to different classes are inequivalent. In contrast, we show that by taking a many-body/Fock space viewpoint it becomes possible to establish equivalences of topological insulators and superconductors in terms of duality transformations. These mappings connect topologically inequivalent systems of fermions, jumping across entries in existent classification tables, because of the phenomenon of symmetry transmutation by which a symmetry and its dual partner have identical algebraic properties but very different physical interpretations. To constrain our study to established classification tables, we define and characterize mathematically Gaussian dualities as dualities mapping free fermions to free fermions (and interacting to interacting). By introducing a large, flexible class of Gaussian dualities we show that any insulator is dual to a superconductor, and that fermionic edge modes are dual to Majorana edge modes, that is, the Gaussian dualities of this paper preserve the bulk-boundary correspondence. Transmutation of relevant symmetries, particle number, translation, and time reversal is also investigated in detail. As illustrative examples, we show the duality equivalence of the dimerized Peierls chain and the Majorana chain of Kitaev, and a two-dimensional Kekulé-type topological insulator, including graphene as a special instance in coupling space, dual to a p-wave superconductor. Since our analysis extends to interacting fermion systems we also briefly discuss some such applications.
