description: We study the interactions between a protostar and its circumstellar disc under the influence of an external binary companion to determine the evolution of the mutual stellar spin - disc misalignment angle. The gravitational torque on the disc from an inclined binary makes the disc precess around the binary axis, while the star-disc interaction torque due to the rotation-induced quadrupole makes the stellar spin and the disc angular momentum axes precess around each other. A significant star-disc misalignment angle can be generated from a small initial value as the star-disc system evolves in time such that the two precession frequencies cross each other. This ``secular resonance'' behavior can be understood in a geometric way from the precession dynamics of spin and disc angular momenta. We derive the conditions for such resonance to occur, and find that they can be satisfied for reasonable protostar-disc-binary parameters. The evolution of star-disc inclination is also affected by mass accretion and by magnetic star-disc interaction torques, which can either promote or reduce star-disc misalignment. In general, as long as the initial binary-disc inclination is greater than a few degrees, a variety of star-disc misalignment angles can be generated within the disc lifetimes. We discuss the implications of our results for the stellar spin orientations in binaries, for the alignments/misalignments of protostellar discs and debris discs, and for the stellar obliquities in exoplanetary systems. In particular, if hot Jupiters are produced by the Kozai effect induced by an external stellar companion, then it is likely that ``primordial'' star-disc misalignments are already generated by the star-disc-binary interactions. Even for systems where the Kozai effect is suppressed, misaligned planets may still be produced during the protoplanetary disc phase.

description: A Laguerre geometric local characterization is given of L-minimal surfaces and Laguerre deformations (T-transforms) of L-minimal isothermic surfaces in terms of the holomorphicity of a quartic and a quadratic differential. This is used to prove that, via their Laguerre Gauss maps, the T-transforms of L-minimal isothermic surfaces have constant mean curvature in some translate of hyperbolic 3-space or de Sitter 3-space in Minkowski 4-space, or have mean curvature zero in some translate of a time-oriented lightcone in Minkowski 4-space. As an application, we show that various instances of the Lawson isometric correspondence can be viewed as special cases of the T-transformation of L-isothermic surfaces with holomorphic quartic differential.

description: In modern electronic medical records (EMR) much of the clinically important data - signs and symptoms, symptom severity, disease status, etc. - are not provided in structured data fields, but rather are encoded in clinician generated narrative text. Natural language processing (NLP) provides a means of "unlocking" this important data source for applications in clinical decision support, quality assurance, and public health. This chapter provides an overview of representative NLP systems in biomedicine based on a unified architectural view. A general architecture in an NLP system consists of two main components: background knowledge that includes biomedical knowledge resources and a framework that integrates NLP tools to process text. Systems differ in both components, which we will review briefly. Additionally, challenges facing current research efforts in biomedical NLP include the paucity of large, publicly available annotated corpora, although initiatives that facilitate data sharing, system evaluation, and collaborative work between researchers in clinical NLP are starting to emerge.

description: We study the time evolution of entanglement in a quantum version of the Kac ring. Our model consists of two spin chains and quantum gates instead of the classical markers. The gates take one qubit from each ring at a time as an input and entangle them. Subsequently, one ring is rotated. This protocol creates non-trivial entanglement between the two rings, which we measure by the entanglement entropy. The features of the entanglement evolution can best be understood by using knowledge about the behavior of an ensemble of classical Kac rings. For instance, the recurrence time of this quantum many-body system is twice the length of the chain and "thermalization" only occurs on time scales much smaller than the dimension of the Hilbert space. The model thus elucidates the relation between distribution of measurement results in quantum and classical systems: While in classical systems repeated measurements are performed over an ensemble of systems, the corresponding result is obtained by measuring the same quantum system prepared in an appropriate superposition repeatedly.

Jeff Derksen's Citational Poetics

Publisher: name: Canadian Literature
Year: 2020

description: This paper investigates Jeff Derksen’s citational poetics in The Vestiges, and how this text’s creative practice critically examines the processes of neoliberalization in the present. With citational poetics, I see Derksen’s writing copy and comment on multiple textual forms in order to depict the poem’s role in social observation alongside its ability mobilize and array these textual forms against structures that far exceed the structure of the poem itself. The Vestiges in turn displays how the disparate materials of the long neoliberal moment and the traces of its manifold processes — from critical theory and chart topping hits to overthrown governments — can be brought to bear on the present, and specifically how mobilizing these different kinds of textual and historical matter locate citational poetics within a wider project of anti-capitalist research.

Scalable Automated Detection of Spiral Galaxy Arm Segments

description: Given an approximately centered image of a spiral galaxy, we describe an entirely automated method that finds, centers, and sizes the galaxy and then automatically extracts structural information about the spiral arms. For each arm segment found, we list the pixels in that segment and perform a least-squares fit of a logarithmic spiral arc to the pixels in the segment. The algorithm takes about 1 minute per galaxy, and can easily be scaled using parallelism. We have run it on all ~644,000 Sloan objects classified as "galaxy" and large enough to observe some structure. Our algorithm is stable in the sense that the statistics across a large sample of galaxies vary smoothly based on algorithmic parameters, although results for individual galaxies can sometimes vary in a non-smooth but easily understood manner. We find a very good correlation between our quantitative description of spiral structure and the qualitative description provided by humans via Galaxy Zoo. In addition, we find that pitch angle often varies significantly segment-to-segment in a single spiral galaxy, making it difficult to define "the" pitch angle for a single galaxy. Finally, we point out how complex arm structure (even of long arms) can lead to ambiguity in defining what an "arm" is, leading us to prefer the term "arm segments".

“Tuned every ear towards a tiny lengthening of light”

description: This article posits weak hope, which I characterize as a combination of resignation, optimism, and generative delusion, as a productive framework through which to listen to Winnipeg singer-songwriter John K. Samson’s 2016 album Winter Wheat. In turn, I suggest that engaging closely with Samson’s lyrics offers up a kind of weak, tenuous hope for the listener—though we may not know exactly “what survival means” (“Confessions of a Futon Revolutionist”), we can—in fact, we must—“recommit [ourselves] to the healing of the world” and “pursue a practice that will strengthen [our] heart[s] (“Postdoc Blues”). For the attentive listener, the very act of engaging with the weak hope audible in and enacted by Samson’s lyrics can form part of a practice that “strengthen[s our] heart[s],” by listening closely and imaginatively to the radical, unflinching empathy that Samson models in his precise, demanding song lyrics.

description: We report on the electronic and optical properties of two theoretically predicted stable spinel compounds of the form ZnB2O4, where B = Ni or Cu; neither compound has been previously synthesized, so we compare them to the previously studied p-type ZnCo2O4 spinel. These new materials exhibit spin polarization that is ideal for spintronics applications, and broad conductivity maxima near the valence band edge that facilitate p-type dopability. We show that 3d electrons on the octahedrally coordinated Zn atom fall deep within the valence band and do not contribute significantly to the electronic structure of the material, while the O 2p and tetrahedrally coordinated B 3d electrons hybridize broadly in the shallow valence states, resulting in increasing curvature (i.e., decreased electron effective mass) of valence bands near the band edge. In particular, ZnCu2O4 exhibits high electrical conductivities near the valence band edge that, at sigma = 2 x 10^4 S/cm, are twice the maximum found for ZnCo2O4, a previously synthesized compound in this class of materials. This material also exhibits ferromagnetism in all of its most stable structures, which makes it a good candidate for further study as a dilute magnetic semiconductor.

description: We review a calculation of the quantum corrections to electrical transport in graphene using the trajectory-based semiclassical method. Compared to conventional metals, for graphene the semiclassical propagator contains an additional pseudospin structure, which influences the results for weak localization, and interaction-induced effects, such as the Altshuler-Aronov correction and dephasing. Our results apply to a sample of graphene that is doped away from the Dirac point and subject to a smooth disorder potential, such that electrons follow classical trajectories. In such system, the Ehrenfest time enters as an additional timescale.

description: Recent models of gender view gender expression, the performative aspect of gender, as an essential component of one’s gender (Hyde et al., 2018; Tate et al., 2014). The way a person dresses, walks, and speaks can all comprise a person’s gender expression. However, if gender is in part a performance, who is the “audience,” and how are they reacting to the performance? This dissertation focuses on how one’s gender is interpreted by others. In five chapters, this work explores audience reactions to gender performances, examining how gender perceptions are formed, how they can differ from a performer’s intent, and the larger consequences of gender perceptions for both the one making the perception and the one being perceived. The first set of studies examines how gender perceptions occur spontaneously and can be affected by both contextual and individual differences. The later studies examine the effects of gender perceptions in conjunction with the effects of a person’s actual gender. The results from these studies conclude that gender perceptions can have a greater effect on certain outcomes, focusing on career-related outcomes, than a person’s actual gender. This work identifies both predictors of perceived gender and effects of perceived gender, noting that gender perceptions affect both the individual who is making the gender perception and the individual that is being perceived. Ultimately, this work pushes for an expanded understand of gender, one which incorporates gender perceptions to better understand how gender functions in everyday social interactions.
Towards Space Solar Power - Examining Atmospheric Interactions of Power Beams with the HAARP Facility

description: In the most common space solar power (SSP) system architectures, solar energy harvested by large satellites in geostationary orbit is transmitted to Earth via microwave radiation. Currently, only limited information about the interactions of microwave beams with energy densities of several tens to hundreds of W/m$^2$ with the different layers of the atmosphere is available. Governmental bodies will likely require detailed investigations of safety and atmospheric effects of microwave power beams before issuing launch licenses for SSP satellite systems. This paper proposes to collect representative and comprehensive data of the interaction of power beams with the atmosphere by extending the infrastructure of the High Frequency Active Auroral Research Program (HAARP) facility in Alaska, USA. Estimates of the transmission infrastructure performance as well as measurement devices and scientific capabilities of possible upgrade scenarios will be discussed. The proposed upgrade of the HAARP facility is expected to deliver a wealth of data and information which could serve as a decision base for governmental launch licensing of SSP satellites, and which can be used in addition to deepen public acceptance of SSP as a large-scale renewable energy source.

description: The OLYMPUS experiment was designed to measure the ratio between the positron-proton and electron-proton elastic scattering cross sections, with the goal of determining the contribution of two-photon exchange to the elastic cross section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, $μ_p G^p_E/G^p_M$, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01~GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately $25^\circ$--$75^\circ$. Symmetric Møller/Bhabha calorimeters at $1.29^\circ$ and telescopes of GEM and MWPC detectors at $12^\circ$ served as luminosity monitors. A total luminosity of approximately 4.5~fb$^{-1}$ was collected over two running periods in 2012. This paper provides details on the accelerator, target, detectors, and operation of the experiment.

description: We integrate the all-electron electronic structure code FHI-aims into the general ChemShell package for solid-state embedding (QM/MM) calculations. A major undertaking in this integration is the implementation of pseudopotential functionality into FHI-aims to describe cations at the QM/MM boundary through effective core potentials and therewith prevent spurious overpolarization of the electronic density. Based on numeric atomic orbital basis sets, FHI-aims offers particularly efficient access to exact exchange and second order perturbation theory, rendering the established QM/MM setup an ideal tool for hybrid and double-hybrid level DFT calculations of solid systems. We illustrate this capability by calculating the reduction potential of Fe in the Fe-substituted ZSM-5 zeolitic framework and the reaction energy profile for (photo-)catalytic water oxidation at TiO2(110).

Рассмотрены различные варианты страхования посева культуры применением малотоксичных гербицидов, что является важным звеном повышения урожайности корнеплодов. В вариантах с применением гербицидов группы бетаналов в минимальных нормах расхода в комбинации со страховыми гербицидами урожайность корнеплодов сахарной свёклы повышалась до 12 % в сравнении с вариантом без страховых гербицидов. В случае применения природной щелочной воды (рН выше 8,5) для приготовления баковой смеси гербицидов необходимо добавлять в неё подкислитель или исключить гербициды бетанальной группы, а выстраивать схему борьбы с сорняками с устойчивыми препаратами в щелочной среде. Приведённые схемы борьбы с сорняками универсальны и могут быть применены с любыми аналоговыми гербицидами различных фирм производителей пестицидов
description: Working schemes of herbicide for safe and effective weed control in sugar beet fields have been suggested. There have been considered different variants of sugar beet field insuring that is an important element of beet root yield improvement. In the variants using minimal consumption rates of betanal group herbicides in combination with insuring herbicides, sugar beet root yield increases up to 12 % as compared to the variant without insuring herbicides. In case of using natural alkaline water (pH being above 8.5) to prepare tank mix of betanal group herbicides, it is necessary to add water acidifier or do not allow application of betanal group herbicides, but to make a weed control scheme using chemicals resistant to alkaline medium. The presented schemes of weed control are universal and can be used with any analog herbicides of different pesticide producing companies.
Se redéfinir dans la langue colonisatrice. Nouvelles voix autochtones francophones

description: L’écriture littéraire dans la langue colonisatrice est un choix conscient pour l’auteur.trice autochtone. Dans Chroniques de Kitchike de Louis-Karl Picard-Sioui (Wendat) et de Bréviaire du matricule 082 de Maya Cousineau-Mollen (Innu), ces deux nouvelles voix littéraires illustrent la dépossession identitaire des leur. Chez P.-Sioui, la réappropriation passe par l’humour et les jeux sémantiques. Dans ses nouvelles, il illustre les travestissements identitaires en jouant sur les vocables et en soulignant le caractère fictif de la connaissance des langues ancestrales. Pour C.-Mollen, la réappropriation de la narration identitaire s’exprime plutôt par le sarcasme et la colère. Si, la poétesse joue sur la langue coloniale législative ayant réduit l’identité « indienne » à des chiffres, elle y répond par la résurgence de l’Innu-aïmun. Cela dit, sa réappropriation est également celle de sa condition de femme autochtone revendiquant sa sexualité libérée des fictions coloniales de la princesse ou de la « squaw ».

description: We present two matrix-free methods for approximately solving exact penalty subproblems that arise when solving large-scale optimization problems. The first approach is a novel iterative re-weighting algorithm (IRWA), which iteratively minimizes quadratic models of relaxed subproblems while automatically updating a relaxation vector. The second approach is based on alternating direction augmented Lagrangian (ADAL) technology applied to our setting. The main computational costs of each algorithm are the repeated minimizations of convex quadratic functions which can be performed matrix-free. We prove that both algorithms are globally convergent under loose assumptions, and that each requires at most $O(1/\varepsilon^2)$ iterations to reach $\varepsilon$-optimality of the objective function. Numerical experiments exhibit the ability of both algorithms to efficiently find inexact solutions. Moreover, in certain cases, IRWA is shown to be more reliable than ADAL.

Using a chaotic trajectory sampled under certain rules in order to avoid any attempt to reconstruct the original one, we create a binary pseudo-random keystream that can only be exactly reproduced by someone that has fully knowledge of the communication system parameters formed by a transmitter and a receiver and sharing the same initial conditions. The plaintext is XORed with the keystream creating the ciphertext, the encrypted message. This keystream passes the NISTs randomness test and has been implemented in a videoconference App for smartphones, in order to show the fast and light nature of the proposed encryption system.
Appraisal of Social Learning Potentials in Some Trending Mobile Computing Applications

description: New Mobile technologies have created a new social dimension where individuals can develop increased levels of their social awareness by keeping in touch with old friends, making new friends, dispense new data or product, and getting information in many more aspects of everyday lives, making one to become more knowledgeable which is very beneficial especially for students. Social networks, in particular enable users to share and discuss common interests and provide infrastructures for integrating various user experiences: synchronous and asynchronous communication, game-playing, sharing links and files. The trend of using social networks and social media to deliver and exchange knowledge could bring a new era of social learning in which learners make use all four language skills of reading, writing, listening and speaking. Unlike a traditional e-leaning paradigm with pre-defined curriculum and standard textbooks, social knowledge could be aggregated on demand, just in time, and in context of engaging challenges from social networks, making learning more exciting, social and, game-like experience. Social learning environment engages the learners in discussion, collaboration, exploration, production, discovery and creation. Schools should harness this to develop group collaboration skills and even project based learning activities that span subjects and grade levels. This paper focuses on technologies and avenues of using mobile phones in supporting open social learning among undergraduate students in Nigeria.

description: Gegenstand dieser Diplomarbeit ist der Entwurf eines Wiener Bildungscampus nach dem Modell „Campus plus“ im Stadtentwicklungsgebiet Nordwestbahnhof. Bei den Wiener Campus+ Modell werden die Bildungsinstitutionen vor allem Kindergarten und Volksschule in einen Bildungsbereich untergebracht, die gemeinsam eine Multifunktionsfläche teilen. Des Weiteren sollte eine Sondergruppe oder eine Sonderklasse wie zum Beispiel Vorschule oder heilpädagogische Gruppe in den Bildungsbereichen geplant werden. Je nach Bedarf kann eine Mittelschule das Angebot ergänzen. Eine stadtteilbezogene Funktion wie eine Musikschule, ein Jugendzentrum oder ähnliche Einrichtungen sollten in den Campus integriert werden, damit auch die Anrainer davon profitieren können.Da das Bildungswesen ständig im Wandel ist, sollte der Schulbau an kontinuierliche Veränderungen angepasst werden. Die innovativen Lehr- und Lernmethoden erfordern neue Räumlichkeiten, die eine traditionelle Schule nicht mehr bieten kann Daher sollten Bildungsbauten an die zeitgemäßen Erfordernisse angepasst werden. Schulen sollen nicht nur als Lernorte betrachtet werden, sondern als Orte des Lernens und Lebens. Dabei soll der Fokus nicht ausschließlich auf die Förderung des Lernens liegen, sondern auch auf Bewegung, Spiel, Ruhe, Kommunikation, Essen und vieles mehr. Deswegen ist es wichtig die Qualitäten der Räumlichkeiten zu erweitern und Mehrfachnutzungen einzuplanen. Bei dem Entwurf werden diese Ansätze berücksichtigt und angewendet.
description: The subject of this diploma thesis is the design of a Viennese educational campus based on the "Campus plus" model in the Nordwestbahnhof urban development area. In the Campus plus model the educational institutions, mainly kindergarten and primary school, are placed in one educational area sharing a multifunctional space together. In addition, a special group or class, such as a preschool or curative education group should be included in the educational area. If necessary, a middle school can be added to this offer. For the benefit of local residents, the Campus Plus model should include neighbourhood functions such as music schools, youth centres or similar facilities.As education is in a constant state of change, school buildings need to be adapted to changing needs. Innovative teaching and learning methods require new spaces that traditional schools can no longer provide. New schools must therefore be adapted to today's needs. Schools should be seen not only as places of learning, but also as places of living. The focus should be on movement, play, rest, communication, eating and many other aspects, not just on promoting learning. Therefore, it is essential to improve the characteristics of school facilities and consider designing them to be multipurpose. These methods are considered and implemented in the design.

description: We use time- and angle-resolved photoemission to measure the nodal non-equilibrium electronic states in various dopings of Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$. We find that the initial pump-induced transient signal of these ungapped states is strongly affected by the onset of the superconducting gap at $T_c$, superconducting pairing fluctuations at $T_p$, and the pseudogap at $T^*$. Moreover, $T_p$ marks a suggestive threshold in the fluence-dependent transient signal, with the appearance of a critical fluence below $T_p$ that corresponds to the energy required to break apart all Cooper pairs. These results challenge the notion of a nodal-antinodal dichotomy in cuprate superconductors by establishing a new link between nodal quasiparticles and the cuprate phase diagram.

description: A remarkable progress has been made in the understanding of the hot and dense QCD matter using lattice gauge theory. The issues which are very well understood as well those which require both conceptual as well as algorithmic advances are highlighted. The recent lattice results on QCD thermodynamics which are important in the context of the heavy ion experiments are reviewed. Instances of greater synergy between the lattice theory and the experiments in the recent years are discussed where lattice results could be directly used as benchmarks for experiments and results from the experiments would be a crucial input for lattice computations.

description: Hydrodynamics and quantum mechanics have many elements in common, as the density field and velocity fields are common variables that can be constructed in both descriptions. Starting with the Schroedinger equation and the Klein-Gordon for a single particle in hydrodynamical form, we examine the basic assumptions under which a quantum system of particles interacting through their mean fields can be described by hydrodynamics.

A Note—Doing the Work with Metonymy
Creators: name: Tracy, Dale
Publisher: name: Canadian Literature
Year: 2020

description: Building on Alicia Elliott’s exhortation to “do the work” in “CanLit is a Raging Dumpster Fire,” I pursue the metonymic after the metaphoric. In metaphor, one thing substitutes for another: the dumpster fire takes the place of the field of relations that creates the conditions for controversies and crises. In contrast, metonymy is contiguous: its readability depends on showing the conventional, assumed, or actual relationships between one thing and another. Metaphor conceals connections; metonymy works by virtue of them. Three recent Canadian plays help me think about what metonymy can add to discourse about doing the work: Daniel MacIvor’s Who Killed Spalding Gray? (2017), Jess Dobkin’s The Magic Hour (2017), and Marcus Youssef and James Long’s Winners and Losers (2015). My strategy is metonymical like “CanLit” is: I read each play for an insight it might offer within the signifying field of Canadian literature, culture, and nation.

description: We construct a Hertzsprung-Russell diagram for the stellar/substellar boundary based on a sample of 63 objects ranging in spectral type from M6V to L4. We report newly observed VRI photometry for all 63 objects and new trigonometric parallaxes for 37 objects. The remaining 26 objects have trigonometric parallaxes from the literature. We combine our optical photometry and trigonometric parallaxes with 2MASS and WISE photometry and employ a novel SED fitting algorithm to determine effective temperatures, bolometric luminosities, and radii. Our uncertainties range from ~20K to ~150K in temperature, ~0.01 to ~0.06 in log(L/Ls}) and 3% to 10% in radius. We check our methodology by comparing our calculated radii to radii directly measured via long baseline optical interferometry. We find evidence for the local minimum in the radius-temperature and radius-luminosity trends that signals the end of the stellar main sequence and the start of the brown dwarf sequence at T ~ 2075K, log(L/Ls)~ -3.9, and (R/Rs) ~ 0.086. The existence of this local minimum is predicted by evolutionary models, but at temperatures ~400K cooler. The minimum radius happens near the locus of 2MASS J0523-1403, an L2.5 dwarf with V-K=9.42. We make qualitative arguments as to why the effects of the recent revision in solar abundances accounts for the discrepancy between our findings and the evolutionary models. We also report new color-absolute magnitude relations for optical and infrared colors useful for estimating photometric distances. We study the optical variability of all 63 targets and find an overall variability fraction of 36^{+9}_{-7}% at a threshold of 15 milli-magnitudes in the I band, in agreement with previous studies.

Protecting Privacy on the Web: A Study of HTTPS and Google Analytics Implementation in Academic Library Websites

description: This presentation describes published research that examined the extent to which HTTPS encryption and Google Analytics services have been implemented on academic library websites, and discusses the privacy implications of free services that introduce web tracking of users. The home pages of 279 academic libraries were analyzed for the presence of HTTPS, Google Analytics services and privacy-protection features. Results indicate that HTTPS implementation on library websites is not widespread, and many libraries continue to offer non-secured connections without an automatically enforced redirect to a secure connection. Furthermore, a large majority of library websites included in the study have implemented Google Analytics and/or Google Tag Manager, yet only very few connect securely to Google via HTTPS or have implemented Google Analytics IP anonymization. Librarians are encouraged to increase awareness of this issue and take concerted and coherent action across five interrelated areas: implementing secure web protocols (HTTPS), user education, privacy policies, informed consent and risk/benefit analyses.
Alice Munro’s “Providence,” Second-Wave Feminism, and the (Im)possibilities of Reconciling Motherhood and Liberation
Creators: name: Getz, Kristina
Publisher: name: Canadian Literature
Year: 2020

description: Amidst the theoretical and discursive landscape of 1970s liberationist feminism, Alice Munro published her 1978 short-story cycle, Who Do You Think You Are? The seventh story in the collection, “Providence,” remains one of the earliest examples of Canadian prose which explicitly explores the conflicts inherent to women’s experiences of feminist liberation and motherhood, and is among Munro's least critically explored stories. “Providence” captures the tenuous and exquisite experience of single-mothering a young child, its difficulties and sacrifices, and the equally painful and (still) unspeakable choice to leave one’s maternal role behind. Munro's central protagonist ultimately chooses feminist liberation over motherhood, unable to reconcile her desire for personal autonomy and freedom from the patriarchal family with her daughter’s need to be mothered.

description: Natural regeneration in tropical forests is considered an essential part of forest restoration efforts; however, it is often under-estimated where the main focus has traditionally been on tree planting. This study assessed natural regeneration and its potential for the conservation of native tree species in Sitapahar Forest Reserve, Bangladesh. We established 99 temporary plots (2 m × 2 m each) in three canopy classes, namely dense canopy (DC, 70–100% canopy coverage), moderate canopy (MC, 40–70%), and open canopy (OC, <40%). In each plot, regenerating tree species were counted, identified, and height (m), collar diameter (cm), and diameter at breast height (dbh, cm) were measured. We identified 79 regenerating tree species under 31 plant families of which 61 were found in DC areas followed by 56 and 36 in MC and OC areas, respectively. Most of the species in DC areas were late-successional, while the OC areas were dominated by early successional species. Diversity and density of regeneration were lowest in OC areas. Findings of this study suggest harnessing biodiversity conservation by promoting natural regeneration and identifying the areas with higher potential for assisted natural regeneration that will enable in situ conservation of rare and vulnerable species by protecting them from further erosion.

A novel variability-based method for quasar selection: evidence for a rest frame ~54 day characteristic timescale

description: We compare quasar selection techniques based on their optical variability using data from the Catalina Real-time Transient Survey (CRTS). We introduce a new technique based on Slepian wavelet variance (SWV) that shows comparable or better performance to structure functions and damped random walk models but with fewer assumptions. Combining these methods with WISE mid-IR colors produces a highly efficient quasar selection technique which we have validated spectroscopically. The SWV technique also identifies characteristic timescales in a time series and we find a characteristic rest frame timescale of ~54 days, confirmed in the light curves of ~18000 quasars from CRTS, SDSS and MACHO data, and anticorrelated with absolute magnitude. This indicates a transition between a damped random walk and $P(f) \propto f^{-1/3}$ behaviours and is the first strong indication that a damped random walk model may be too simplistic to describe optical quasar variability.
