description: Temperate habitats in Himalaya have undergone drastic changes in last decades, resulting in increased anthropogenic activities causing ambient air pollution. Biomonitors such as lichens due to their slow growth rate and, longer life span, and absorption of nutrients from atmosphere only, are used for studying atmospheric deposition of heavy metals along natural and anthropogenic gradients in various ecosystems. In the current study four species of lichenized fungal family Physciaceae (Phaeophyscia hispidula (Ach.) Moberg, Physcia alba (Fée) Müll. Arg., Phaeophyscia endococcina (Körb.) and Physcia abuensis D.D. Awasthi & S.R. Singh) were analysed for heavy metal (Al, Fe, Zn, Cu, Pb) deposition from five sites in Thal Kedar sacred forest land scape with reference to distance from road. Maximum heavy metal deposition in all lichen species was recorded in sites with proximity to the road. Among the heavy metals analysed iron and aluminium were predominantly accumulated followed by zinc, copper and lead. Phaeophyscia hispidula was present in four of the five sites studied appropriating as an ideal bioindicator of heavy metal pollution in the region.
Systemic epinephrine and defensive burying in the rat
Creators: name: Terlecki, Lori Janine

description: Many investigators have suggested that epinephrine influences the behaviour of organisms in aversive situations; however, attempts to confirm this prediction by examining the effects of adrenal demedullation and epinephrine injections on the performance of rats in traditional aversive conditioning paradigms have failed to provide unambiguous support for this point of view. In the present investigations, the recently developed defensive burying paradigm was used to assess the effects of epinephrine on the behaviour of rats in aversive situations. Defensive burying refers to the fact that rats typically respond to well-defined aversive objects by pushing moveable material towards and over them. Rats with demedullated adrenal glands, and therefore reduced systemic levels of epinephrine, exhibited reduced levels of burying of an unconditioned aversive stimulus (Experiments 5 and 6). This reduction of burying observed in demedullated rats was counteracted by replacement injections of epinephrine (Experiment 6). Intact rats given systemic injections of .01, .1, .5 or 1 mg/kg of epinephrine exhibited increased levels of burying of both unconditioned and conditioned aversive stimuli (Experiments 1, 2, 3, 4, and 6); whereas, a larger dose (2 mg/kg) of epinephrine produced an obvious motor impairment (Experiment 4). These findings clearly confirm the hypothesis of a relation between levels of epinephrine and the responsiveness of organisms to aversive stimulation. Furthermore, the systematic and robust nature of these results illustrates the utility of the defensive burying paradigm in the investigation of epinephrine-behaviour relations and the mechanisms that underlie them.

description: We present the design and evaluation of a web-based intelligent writing assistant that helps students recognize their revisions of argumentative essays. To understand how our revision assistant can best support students, we have implemented four versions of our system with differences in the unit span (sentence versus sub-sentence) of revision analysis and the level of feedback provided (none, binary, or detailed revision purpose categorization). We first discuss the design decisions behind relevant components of the system, then analyze the efficacy of the different versions through a Wizard of Oz study with university students. Our results show that while a simple interface with no revision feedback is easier to use, an interface that provides a detailed categorization of sentence-level revisions is the most helpful based on user survey data, as well as the most effective based on improvement in writing outcomes.

description: We consider the phase transition of a string with tension $\eps_1$ to a string with a smaller tension $\eps_2$. The transition proceeds through quantum tunneling, and we calculate in arbitrary number of dimensions the pre-exponential factor multiplying the leading semiclassical exponential expression for the rate of the process. At $\eps_2=0$ the found formula for the decay rate also describes a break up of a metastable string into two pieces.

description: Human annotations are vital to supervised learning, yet annotators often disagree on the correct label, especially as annotation tasks increase in complexity. A strategy to improve label quality is to ask multiple annotators to label the same item and aggregate their labels. Many aggregation models have been proposed for categorical or numerical annotation tasks, but far less work has considered more complex annotation tasks involving open-ended, multivariate, or structured responses. While a variety of bespoke models have been proposed for specific tasks, our work is the first to introduce aggregation methods that generalize across many diverse complex tasks, including sequence labeling, translation, syntactic parsing, ranking, bounding boxes, and keypoints. This generality is achieved by devising a task-agnostic method to model distances between labels rather than the labels themselves.
 This article extends our prior work with investigation of three new research questions. First, how do complex annotation properties impact aggregation accuracy? Second, how should a task owner navigate the many modeling choices to maximize aggregation accuracy? Finally, what diagnoses can verify that aggregation models are specified correctly for the given data? To understand how various factors impact accuracy and to inform model selection, we conduct simulation studies and experiments on real, complex datasets. Regarding testing, we introduce unit tests for aggregation models and present a suite of such tests to ensure that a given model is not mis-specified and exhibits expected behavior.
 Beyond investigating these research questions above, we discuss the foundational concept of annotation complexity, present a new aggregation model as a bridge between traditional models and our own, and contribute a new semi-supervised learning method for complex label aggregation that outperforms prior work.

description: Landauer's principle is applied to information in the universe. Once stars began forming, the increasing proportion of matter at high stellar temperatures compensated for the expanding universe to provide a near constant information energy density. The information equation of state was close to the dark energy value, w = -1, for a wide range of redshifts, 10> z >0.8, over one half of cosmic time. A reasonable universe information bit content of only 10^87 bits is sufficient for information energy to account for all dark energy. A time varying equation of state with a direct link between dark energy and matter, and linked to star formation in particular, is clearly relevant to the cosmic coincidence problem.In answering the "Why now?" question we wonder "What next?" as we expect the information equation of state to tend towards w = 0 in the future.

description: Is Newton's gravity sufficient to handle the weakly nonlinear evolution stages of the cosmic large-scale structures? Here we resolve the issue by analytically deriving the density and velocity power spectra to the second order in the context of Einstein's gravity. The recently found pure general relativistic corrections appearing in the third-order perturbation contribute to power spectra to the second order. In this work the complete density and velocity power spectra to the second order are derived. The power transfers among different scales in the density power spectrum are estimated in the context of Einstein's gravity. The relativistic corrections in the density power spectrum are estimated to be smaller than the Newtonian one to the second order, but these could be larger than higher-order nonlinear Newtonian terms.

description: The study recorded three terricolous lichen species belonging to three genera and five families. Fruticose lichen Stereocaulon foliolosum was dominant species, present in 3 of the four sampling sites; covering an altitudinal range of 3026- 3789 m followed by two foliose species Umbilicaria indica and Cetrelia pseudolivetorum, present only at lower elevation {2817-3026 m) sites. Highest concentration of total PAHs were recorded in fruticose species Stereocaulon foliolosum . PCA and further correlation studies concluded that there was no significant correlation between macroscale environmental variables and, PAHs naphthalene, fluorine, benz[a] pyrene were primarily accumulated by terricolous lichens. Diagnostic ratios concluded a mix source (both domestic fuel wood combustion and automobile exhaust) of PAHs in the area. The overall dominant presence and constancy of grazing tolerant fruticose species (Stereocaulon foliolosum) in the area with relatively higher accumulation of PAHs than other recorded foliose species, indicate the efficient capability of fruticose growth forms as biomonitors in alpine grasslands of Garhwal Himalaya.
Superdiffusion in the Dissipative Standard Map

description: We consider transport properties of the chaotic (strange) attractor along unfolded trajectories of the dissipative standard map. It is shown that the diffusion process is normal except of the cases when a control parameter is close to some special values that correspond to the ballistic mode dynamics. Diffusion near the related crisises is anomalous and non-uniform in time: there are large time intervals during which the transport is normal or ballistic, or even superballistic. The anomalous superdiffusion seems to be caused by stickiness of trajectories to a non-chaotic and nowhere dense invariant Cantor set that plays a similar role as cantori in Hamiltonian chaos. We provide a numerical example of such a sticky set. Distribution function on the sticky set almost coincides with the distribution function (SRB measure) of the chaotic attractor.

description: We have studied a one dimensional Hubbard superlattice with different Coulomb correlations at alternating sites for a half-filled band. Mean field calculations based on the Hartree-Fock approximation together with a real space renormalization group technique were used to study the ground state of the system. The phase diagrams obtained in these approaches agree with each other from the weak to the intermediate coupling regime. The mean field results show very quick convergence with system size. The renormalization group results indicate a spatial modulation of local moments that was identified in some previous work. Also we have studied the magnetoconductance of such superlattices which reveals several interesting points.

description: As the year 2020 came to a close, several new strains have been reported for the SARS-CoV-2 coronavirus, the agent responsible for the COVID-19 pandemic that has afflicted us all this past year. However, it is difficult to comprehend the scale, in sequence space, geographical location and time, at which SARS-CoV-2 mutates and evolves in its human hosts. To get an appreciation for the rapid evolution of the coronavirus, we built interactive scalable vector graphics (SVG) maps that show daily nucleotide variations in genomes from the six most populated continents compared to that of the initial, ground-zero SARS-CoV-2 isolate sequenced at the beginning of the year. The attached compressed file package comprises SARS-CoV-2 mutation timemaps SVG files for 2020 and 2021, updated with data submitted to GISAID as of January 25th 2021 (inclusive). It is a snapshot of the webpage hosting these maps (https://bcgsc.github.io/SARS2) on that day and includes the script and single nucleotide variation (SNV) report files used to generate these and could be used by anyone to generate additional and custom interactive SVG maps. It supplements our F1000research article. The frequently updated SARS-CoV-2 genome SNV reports (https://www.bcgsc.ca/downloads/btl/SARS-CoV-2/mutations) represent a wealth of information that could be mined to gain further insights into the rapid SARS-CoV-2 coronavirus evolution in human hosts.

USA: Arizona: Cochise Co. (Huachuca Mts) and Santa Cruz Co. (Atascosa, Patagonia, and Santa Rita Mts). Diagnosis. Bryolymnia anthracitaria can be recognized by its grayish-brown forewing with almost all of the basal and antemedial areas blackish brown and with a thick blackish-brown streak extending from the orbicular spot (in some specimens from the antemedial line) to the terminal line. The reniform and orbicular spots are outlined in black and the postmedial line is black but the lines are thin, so they tend to be partially covered and obscured by the prominent dark streak. Th e subterminal line is pale and usually obscure, being most evident near the costa because of black shading in the upper part of the subterminal area adjacent to the line. Forewing length ranges from 12–16 mm with males averaging 1.7 mm larger than females (Ferris and McFarland 2007). In the male the hindwing is pale fuscous with darker fuscous on the veins, discal spot, and wing margin. In the female the hindwing is dark fuscous, slightly paler toward the wing base. Male genitalia. These are similar to those of Bryolymnia biformata, but in B. anthracitaria the dorsal surface of the clasper is serrated, the clasper is without a basal dorsal process, the digitus is much larger and widens apically into a plate that is serrated on both sides, and the vesica is more globular with two stout cornuti. Female genitalia. These also are similar to those of Bryolymnia biformata, but in B. anthracitaria the corpus bursae is more elongated and the ductus bursae is completely sclerotized and markedly expanded anteriorly and posteriorly. Distribution and biology. Bryolymnia anthracitaria is known only from southeastern Arizona where it has been collected in oak scrub grassland. Collecting dates range from late June to late August.

description: Temperate habitats in Himalaya have undergone drastic changes in last decades, resulting in increased anthropogenic activities causing ambient air pollution. Biomonitors such as lichens due to their slow growth rate and, longer life span, and absorption of nutrients from atmosphere only, are used for studying atmospheric deposition of heavy metals along natural and anthropogenic gradients in various ecosystems. In the current study four species of lichenized fungal family Physciaceae (Phaeophyscia hispidula (Ach.) Moberg, Physcia alba (Fée) Müll. Arg., Phaeophyscia endococcina (Körb.) and Physcia abuensis D.D. Awasthi & S.R. Singh) were analysed for heavy metal (Al, Fe, Zn, Cu, Pb) deposition from five sites in Thal Kedar sacred forest land scape with reference to distance from road. Maximum heavy metal deposition in all lichen species was recorded in sites with proximity to the road. Among the heavy metals analysed iron and aluminium were predominantly accumulated followed by zinc, copper and lead. Phaeophyscia hispidula was present in four of the five sites studied appropriating as an ideal bioindicator of heavy metal pollution in the region.
Effects of hypolimnetic aeration on functional components of the lake ecosystem
Creators: name: Ashley, Kenneth Ian
Publisher: name: University of British Columbia
Year: 2010

description: The whole-lake experimental approach was used to examine the effect of hypolimnetic aeration on several key components of the lake ecosystem. These included circulation and decomposition processes, major nutrient, ion and-pH interactions as well as phytoplankton and zooplankton populations. A small (3.9 ha, Z max.=9.0 m) naturally eutrophic lake was divided into experimental and control halves by a plastic curtain, and a hypolimnetic aerator installed in the experimental half and operated from April 1978 to March 1979. Hypolimnetic aeration had no effect on thermal stratification during the ice-free season but circulated the entire experimental half under ice cover. Aeration increased hypolimnetic turbidity but did not affect epilimnetic transparency. Hypolimnetic oxygen levels were increased along with a ten fold rise in oxygen consumption. Hypolimnetic ammonia levels were reduced and sufficient oxygen was added for nitrification to occur. Internal phosphorous loading and hypolimnetic orthophosphate levels were also reduced however aerobic P regeneration, increased. Aeration vented accumulated CO₂ from the hypolimnion and decreased its calcium, magnesium, bicarbonate and orthophosphate content via calcium carbonate coprecipitation. Phytoplankton abundance and species composition (averaged over the water column) were not affected by hypolimnetic aeration. The zooplankton community exhibited similar vertical distribution on both halves of the lake however greater numbers were found on the experimental half after several months aeration. Management implications of hypolimnetic aeration are also discussed.

description: Canonical correlation analysis (CCA) is a classic statistical method for discovering latent co-variation that underpins two or more observed random vectors. Several extensions and variations of CCA have been proposed that have strengthened our capabilities in terms of revealing common random factors from multiview datasets. In this work, we first revisit the most recent deterministic extensions of deep CCA and highlight the strengths and limitations of these state-of-the-art methods. Some methods allow trivial solutions, while others can miss weak common factors. Others overload the problem by also seeking to reveal what is not common among the views -- i.e., the private components that are needed to fully reconstruct each view. The latter tends to overload the problem and its computational and sample complexities. Aiming to improve upon these limitations, we design a novel and efficient formulation that alleviates some of the current restrictions. The main idea is to model the private components as conditionally independent given the common ones, which enables the proposed compact formulation. In addition, we also provide a sufficient condition for identifying the common random factors. Judicious experiments with synthetic and real datasets showcase the validity of our claims and the effectiveness of the proposed approach.

description: Utilizing recent DIS measurements (F_{2,L}) and data on dilepton and high-E_{T} jet production we determine the dynamical parton distributions of the nucleon generated radiatively from valence-like positive input distributions at optimally chosen low resolution scales. These are compared with `standard' distributions generated from positive input distributions at some fixed and higher resolution scale. It is shown that up to the next to leading order NLO(\bar{MS}, DIS) of perturbative QCD considered in this paper, the uncertainties of the dynamical distributions are, as expected, smaller than those of their standard counterparts. This holds true in particular in the presently unexplored extremely small-x region relevant for evaluating ultrahigh energy cross sections in astrophysical applications. It is noted that our new dynamical distributions are compatible, within the presently determined uncertainties, with previously determined dynamical parton distributions.

description: How non-coding DNA gives rise to new protein-coding genes (de novo genes) is not well understood. Recent work has revealed the origins and functions of a few de novo genes, but common principles governing the evolution or biological roles of these genes are unknown. To better define these principles, we performed a parallel analysis of the evolution and function of six putatively protein-coding de novo genes described in Drosophila melanogaster. Reconstruction of the transcriptional history of de novo genes shows that two de novo genes emerged from novel long non-coding RNAs that arose at least 5 MY prior to evolution of an open reading frame. In contrast, four other de novo genes evolved a translated open reading frame and transcription within the same evolutionary interval suggesting that nascent open reading frames (proto-ORFs), while not required, can contribute to the emergence of a new de novo gene. However, none of the genes arose from proto-ORFs that existed long before expression evolved. Sequence and structural evolution of de novo genes was rapid compared to nearby genes and the structural complexity of de novo genes steadily increases over evolutionary time. Despite the fact that these genes are transcribed at a higher level in males than females, and are most strongly expressed in testes, RNAi experiments show that most of these genes are essential in both sexes during metamorphosis. This lethality suggests that protein coding de novo genes in Drosophila quickly become functionally important.

description: The Fabry-Perot scanning interferometer mounted on the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences is used to study the distribution and kinematics of ionized gas in the peculiar galaxy Arp 212 (NGC 7625, III Zw 102). Two kinematically distinct subsystems - the inner disk and outer emission filaments, are found within the optical radius of the galaxy. The first subsystem, at galactocentric distances r<3.5 kpc, rotates in the plane of the stellar disk. The inner part of the ionized-gas disk (r<1.5-2 kpc) exactly coincides with the previously known disk consisting of molecular gas. The second subsystem of ionized gas is located at galactocentric distances 2-6 kpc. This subsystem rotates in a plane tilted by a significant angle to the stellar disk. The angle of orbital inclination in the outer disk increases with galactocentric distance and reaches 50 degrees at r=6 kpc. The ionized fraction of the gaseous disk does not show up beyond this galactocentric distance, but we believe that the HI disk continues to warp and approaches the plane that is polar with respect to the inner disk of the galaxy. Hence Arp 212 can be classified as a galaxy with a polar ring (or a polar disk). The observed kinematics of the ionized and neutral gas can be explained assuming that the distribution of gravitational potential in the galaxy is not spherically symmetric. Most probably, the polar ring have formed via accretion of gas from the dwarf satellite galaxy UGC 12549.

description: Magnetic skyrmions are nanoscale spin textures touted as next-generation computing elements. When subjected to lateral currents, skyrmions move at considerable speeds. Their topological charge results in an additional transverse deflection known as the skyrmion Hall effect (SkHE). While promising, their dynamic phenomenology with current, skyrmion size, geometric effects and disorder remain to be established. Here we report on the ensemble dynamics of individual skyrmions forming dense arrays in Pt/Co/MgO wires by examining over 20,000 instances of motion across currents and fields. The skyrmion speed reaches 24 m/s in the plastic flow regime and is surprisingly robust to positional and size variations. Meanwhile, the SkHE saturates at $\sim 22^\circ$, is substantially reshaped by the wire edge, and crucially increases weakly with skyrmion size. Particle model simulations suggest that the SkHE size dependence - contrary to analytical predictions - arises from the interplay of intrinsic and pinning-driven effects. These results establish a robust framework to harness SkHE and achieve high-throughput skyrmion motion in wire devices.

Frequency-Domain Coherent Control of Femtosecond Two-Photon Absorption: Intermediate-Field vs. Weak-Field Regime

description: Coherent control of femtosecond two-photon absorption in the intermediate-field regime is analyzed in detail in the powerful frequency domain using an extended 4th-order perturbative description. The corresponding absorption is coherently induced by the weak-field non-resonant two-photon transitions as well as by four-photon transitions involving three absorbed photons and one emitted photons. The interferences between these two groups of transitions lead to a difference between the intermediate-field and weak-field absorption dynamics. The corresponding interference nature (constructive or destructive) strongly depends on the detuning direction of the pulse spectrum from half the two-photon transition frequency. The model system of the study is atomic sodium, for which both experimental and theoretical results are obtained. The detailed understanding obtained here serves as a basis for coherent control with rationally-shaped femtosecond pulses in a regime of sizable absorption yields.

description: Singularities in macroscopic systems at discontinuous phase transitions are replaced in finite systems by sharp but continuous changes. Both the energy differences between metastable and stable phases and the energy barriers separating these phases decrease with decreasing particle number. Then, for small enough systems, random heterophasic oscillations of the entire system become an observable form of thermal motion. Under certain conditions, these oscillations take the form of oscillatory nucleation. We discuss mechanisms and observation conditions for these random transitions between phases.

description: Recent research has demonstrated how racial biases against users who write African American English exists in popular toxic language datasets. While previous work has focused on a single fairness criteria, we propose to use additional descriptive fairness metrics to better understand the source of these biases. We demonstrate that different benchmark classifiers, as well as two in-process bias-remediation techniques, propagate racial biases even in a larger corpus. We then propose a novel ensemble-framework that uses a specialized classifier that is fine-tuned to the African American English dialect. We show that our proposed framework substantially reduces the racial biases that the model learns from these datasets. We demonstrate how the ensemble framework improves fairness metrics across all sample datasets with minimal impact on the classification performance, and provide empirical evidence in its ability to unlearn the annotation biases towards authors who use African American English. ** Please note that this work may contain examples of offensive words and phrases.

description: In this study an extended low energy phase diagram for NaxCoO2 is experimentally established with emphasis on the high x range. It is based on systematic heat capacity studies on both polycrystalline and single crystalline samples and on uSR measurements. Main features are the existence of mass enhancement, spin fluctuations without long-range order, and magnetic order with associated Fermi surface gapping. The latter is seen in the electronic density of states (DOS) and suppression of nuclear specific heat. While there is agreement between the band structure and the low energy DOS in the low x range, in the high x range (x > 0.6) the thermodynamically determined DOS is approximately three times that deduced from the angle-resolved photoemission spectroscopy (ARPES)-measured band dispersion or local-density approximation (LDA) calculations.

Rotation of an atomic Bose-Einstein condensate with and without a quantized vortex

description: We theoretically examine the rotation of an atomic Bose-Einstein condensate in an elliptical trap, both in the absence and presence of a quantized vortex. Two methods of introducing the rotating potential are considered - adiabatically increasing the rotation frequency at fixed ellipticity, and adiabatically increasing the trap ellipticity at fixed rotation frequency. Extensive simulations of the Gross-Pitaevskii equation are employed to map out the points where the condensate becomes unstable and ultimately forms a vortex lattice. We highlight the key features of having a quantized vortex in the initial condensate. In particular, we find that the presence of the vortex causes the instabilities to shift to lower or higher rotation frequencies, depending on the direction of the vortex relative to the trap rotation.

description: We construct the classification scheme for all possible evolution scenarios and find the corresponding global geometries for dynamics of a thin spherical vacuum shell in the Schwarzschild-de Sitter metric. This configuration is suitable for the modelling of vacuum bubbles arising during cosmological phase transitions in the early Universe. The distinctive final types of evolution from the local point of view of a rather distant observer are either the unlimited expansion of the shell or its contraction with a formation of black hole (with a central singularity) or wormhole (with a baby universe in interior).
