Roost selection and social organization of myotis in maternity colonies
Creators: name: Rensel, Leah J.
Publisher: name: University of British Columbia
Year: 2021

description: Wild animals often congregate in social groups to enhance individual and group survival. Social cooperation allows animals to share limited resources among conspecifics without incurring the costs of competition. Many reproductive bats demonstrate social cooperation by congregating in maternity colony roosts, which are critical but limited habitat components for North American bat populations. Female myotis bat species may select artificial structures, such as bat boxes and buildings to form their colonies, and may move among multiple roosts throughout the season. Female little brown bats (Myotis lucifugus) and Yuma bats (M. yumanesis), for example, form maternity colonies during the summer to rear their young. I studied two colonies in artificial structures near Vancouver, British Columbia, to assess social behavior and understand what conditions influenced day roost selection. During summer 2019, I used Passive Integrated Technology (PIT-tags and scanners) to track individuals’ daily roost selection. I monitored temperature and humidity at all known roosts and used radio telemetry to find previously unknown roosts. Yuma myotis and little brown myotis used at least 5 roosts at each site and switched locations frequently between roosts. Bats selected roosts within specific temperature ranges likely corresponding to their thermoneutral zone. Bats were less likely to switch during lactation when the pups were vulnerable and most likely to leave a roost during post-lactation when the pups were volant. Yuma myotis and little brown myotis formed strong, close associations with conspecifics during pregnancy and lactation, which then fragmented during post lactation when adults could roost independently with volant pups. Little brown myotis left the maternity site in August, while Yuma myotis persisted until September. During this time, Yuma myotis mixed with conspecifics from nearby maternity colonies in a previously unoccupied roost. My findings suggest land managers should ensure that multiple nearby roosts are available to maternity colonies, as bats in a maternity colony require a range of temperatures and roost types during the summer. Yuma myotis and little brown myotis may have similar roost requirements, but different social behavior, suggesting that these two species have different life history patterns.

description: Fondé il y a un siècle en tant que musée classique d’ethnographie régionale, le Musée de la Vie wallonne se trouve aujourd’hui face au défi d’une indispensable actualisation et redéfinition de son projet muséal. Depuis environ dix ans, le choix de l’approche dite de « musée de société », retenue à l’occasion de la rénovation totale de l’établissement, a entraîné la révision en profondeur des politiques d’acquisition et d’exposition, mais aussi de la nature des recherches sur le terrain et des relations entretenues avec les différents publics. Au travers de cet article, nous tentons de montrer les implications concrètes de la transposition de ce nouveau modèle sur l’ensemble des fonctions muséales, qui place désormais l’homme plutôt que les collections au centre du discours et dont l’un des objectifs fondamentaux est de permettre au sein du Musée la mise en valeur des enjeux parfois complexes de la société contemporaine.
description: Founded a century ago as a classical museum of regional ethnography, the Museum of Walloon Life is now facing the challenge of an essential update and the redefinition of its museum project. For about ten years, the choice of the approach known as "society museum" on the occasion of the total renovation of the building, led to an in-depth review of the acquisition and exhibition policies but also of the nature of field research and relationships with its different audiences. This article shows the practical consequences of the implementation of this new model, which now places the man rather than the collections at the center of discourse, on all museum functions. One of its fundamental objectives is to allow the development within the Museum of the sometimes complex issues of contemporary society.

description: The present investigation has been made to study the distribution, qualitative composition, of zooplankton from the eastern Arabian Sea of the habitat from Sundarapandian Pattinamand Manamelkudi (9° 40’ N; 69° 20’ E) along the Palk Strait of east coast of Tamil Naduduring. From July 2005 to June 2006, the zooplankton was sampled every three months for each monsoon seasons. The studied sites are located in one of the most productive zones of the world. Zooplankton species associations were studied using a null model species co‐occurrence. The results revealed the absence of regulators only for Zooplankton in station II in fixed-fixed model. In spite of these results would not agree with the literature descriptions, the cause would be the presence of many repeated species for studied sites. Ecological fisheries and resources management were discussed.

description: Nano tricalcium phosphate particles were prepared by a wet method from aqueous solutions and characterized using TEM, XRD, and BET-N2 adsorption measurements. The potential of the synthesized nano tricalcium phosphate particles to remove Pb2+ cations from aqueous solutions was investigated in batch reactor under different experimental condition. The effects of initial concentration, adsorbent dosage, contact time and temperature were studied in batch experiments. The sorption of Pb2+ by nano-TCP increased as the initial concentration of lead ion increased in the medium. Various thermodynamic parameters, such as G°, H° and S° were calculated. Thermodynamics of Pb2+ cation sorption onto nano-TCP system pointed at spontaneous and endothermic nature of the process. The pseudo-first order, pseudo-second order and intraparticle diffusion kinetic models were applied to study the kinetics of the sorption processes. The pseudo-second order kinetic model provided the best correlation (R2 > 0.999) of the used experimental data compared to the pseudo-first order and intraparticle diffusion kinetic models.  The maximum Pb2+ adsorbed was found to be 4761.90 mg/g. It was found that the sorption of Pb2+ on nano-TCP was correlated well (R2 = 0.982) with the Langmuir equation as compared to Freundlich and Dubinin–Kaganer–Radushkevich (D-K-R) isotherm equation under the concentration range studied. This study indicated that nano-TCP could be used as an efficient adsorbent for removal of Pb2+ from aqueous solution.

description: We measure alignments on scales of 1 Mpc $h^{-1}_{71}$ for galaxies in Abell 1689 ($z=0.18$) from an existing Hubble Space Telescope mosaic. We find evidence of galaxy alignment in the inner 500 $h^{-1}_{71}$ kpc. The alignment appears to be stronger towards the centre and is mostly present among the fainter galaxies, while bright galaxies are unaligned. This is consistent with a model where alignments originate from tidal locking.

description: Le massif de Serpont est un petit massif cambro-ordovicien localisé au centre de la province du Luxembourg, entre les villes de Libramont-Chevigny, Bras et Libin, au Sud-Est de la Belgique. Celui-ci est bordé de plusieurs ruisseaux traversant principalement le conglomérat Lochkovien de la Formation de Fépin.L’or alluvionnaire se retrouve sous la forme de paillettes et de grains, le plus souvent « modifiés », et contenant parfois des inclusions de quartz. Les analyses chimiques ont décelé des teneurs inférieures à 7 % en poids d’argent, excepté pour un grain correspondant à de l’électrum, ainsi que des traces de cuivre et de fer. Tous ces éléments sont répartis de manière homogène dans chaque grain. L’origine de l’or est probablement à la fois filonienne, mis en place lors de la formation de fluides métamorphiques tardi-varisques (500 °C et 300-400 MPa) dans un contexte de « shear zone », et détritique, c’est-à-dire contenu au sein des conglomérats et arkoses éodévoniens de la Formation de Fépin. Les minéraux denses associés à l’or sont : le grenat (almandin-spessartine-grossulaire), la magnétite, la tourmaline (schörl – dravite), le zircon, le chloritoïde, l’ilménite, le rutile et la pyrite.
description: The Serpont Massif is a small Cambro-Ordovician Massif located in the centre of the Luxembourg province, between the cities of Libramont-Chevigny, Bras and Libin, in the South East of Belgium. The Massif is covered by many water streams mainly situated in the surrounding of Lochkovian conglomerate of the “Fépin Formation”.Alluvial gold is dispersed with an appearance of grains and specks, most often in a "modified" form, containing sometimes quartz inclusions. Chemical analyses detected contents of silver below 7 wt%, except for a grain corresponding to electrum; traces of copper and iron were also observed. All these elements are distributed homogeneously in each grain. The origin of gold is probably related to the formation of veins, mostly set up during the Variscan metamorphic event (500 °C and 300-400 MPa) in a “shear zone” context, and its release from the lower Devonian conglomerates of the “Fépin Formation” by erosion. These events seem similar to those that occur in the Stavelot Massif in Belgium. Heavy alluvial minerals associated with gold are garnet (almandine - spessartine – grossular typical of Ardennes), magnetite, tourmaline (schorl - dravite), zircon, chloritoid, ilmenite, rutile and pyrite.

description: N=4 supersymmetric Yang-Mills theory exhibits a rather surprising duality of Wilson-loop vacuum expectation values and scattering amplitudes. In this paper, we investigate this correspondence at the diagram level. We find that one-loop triangles, one-loop boxes, and two-loop diagonal boxes can be cast as simple one- and two- parametric integrals over a single propagator in configuration space. We observe that the two-loop Wilson-loop "hard-diagram" corresponds to a four-loop hexagon Feynman diagram. Guided by the diagrammatic correspondence of the configuration-space propagator and loop Feynman diagrams, we derive Feynman parameterizations of complicated planar and non-planar Feynman diagrams which simplify their evaluation. For illustration, we compute numerically a four-loop hexagon scalar Feynman diagram.

description: In the past decade computational biology has grown from a cottage industry with a handful of researchers to an attractive interdisciplinary field, catching the attention and imagination of many quantitatively-minded scientists. Of interest to us is the key role played by the EM algorithm during this transformation. We survey the use of the EM algorithm in a few important computational biology problems surrounding the "central dogma"; of molecular biology: from DNA to RNA and then to proteins. Topics of this article include sequence motif discovery, protein sequence alignment, population genetics, evolutionary models and mRNA expression microarray data analysis.

description: The Cooperative Tagging Center (CTC) began as the Cooperative Game Fish Tagging Program (GTP) at Woods Hole Oceanographic Institute (WHOI) in 1954. The GTP was started by Dr. Frank J. Mather III with an initial focus on bluefin tuna (Thunnus thynnus). The program expanded to officially include billfish in 1973 and became a joint effort between the National Marine Fisheries Service (NMFS) and WHOI. In 1980, the Miami Laboratory of the NMFS’s Southeast Fisheries Science Center (SEFSC) took complete responsibility for the operation, funding, and maintenance of the GTP. In 1992, the SEFSC changed the program name to the CTC due to an increase in tagging efforts for a wider variety of species, as well as an increase in tagging research needs and requests for tagging data. Between 1954 and 2023, 276,564 fish of 125 different species or species groups were marked using the CTC’s conventional tags. Until recently, the CTC has focused on the tagging of billfish and tuna in the Atlantic Ocean, Gulf  of America, Caribbean Sea, and the Mediterranean Sea, however, in 2024 we will be expanding the program to include coastal pelagics in these same regions. In addition to billfish and tuna, the new suite of approved species include the following coastal pelagic species: king mackerel, spanish mackerel, greater amberjack, almaco jack, jack crevalle, cobia, and gray triggerfish.

description: The dynamics of a tracer particle in a glassy matrix of obstacles displays slow complex transport as the free volume approaches a critical value and the void space falls apart. We investigate the emerging subdiffusive motion of the test particle by extensive molecular dynamics simulations and characterize the spatio-temporal transport in terms of two-time correlation functions, including the time-dependent diffusion coefficient as well as the wavenumber-dependent intermediate scattering function. We rationalize our findings within the framework of critical phenomena and compare our data to a dynamic scaling theory.

Une enquête sur terrain a été réalisée à partir d’un échantillon représentatif de 190 médecins soit (51%) des praticiens privés installés dans les douze communes de la wilaya. Les résultats obtenus montrent que les médecins avancent les mêmes motifs : avant tout les conditions d’exercice (environnementaux) avec (49 %) puis la qualité de vie personnelle /familiale (42 %). Les motifs d’installation des médecins divergent et varient entre les communes de la wilaya mais aussi entre les zones d\'une même commune. Ces résultats suggèrent que les médecins privés, notamment les nouveaux installés, adaptent l’exercice libéral à leur mode de vie et que les villes centres sont mieux équipées que les communes périphériques. Les territoires ruraux sont sous- équipés en particulier les zones à faible densité de population.

description: We investigate the statistical properties of the correlation matrix between individual stocks traded in the Korean stock market using the random matrix theory (RMT) and observe how these affect the portfolio weights in the Markowitz portfolio theory. We find that the distribution of the correlation matrix is positively skewed and changes over time. We find that the eigenvalue distribution of original correlation matrix deviates from the eigenvalues predicted by the RMT, and the largest eigenvalue is 52 times larger than the maximum value among the eigenvalues predicted by the RMT. The $β_{473}$ coefficient, which reflect the largest eigenvalue property, is 0.8, while one of the eigenvalues in the RMT is approximately zero. Notably, we show that the entropy function $E(σ)$ with the portfolio risk $σ$ for the original and filtered correlation matrices are consistent with a power-law function, $E(σ) \sim σ^{-γ}$, with the exponent $γ\sim 2.92$ and those for Asian currency crisis decreases significantly.

description: The idea of starting an astronomical observatory in the state of Uttar Pradesh in India germinated through the initiative of a scholarly statesman Babu Sampurnanandji. His interest in astrology coupled with his academic bent of mind got him interested in modern astronomy. Being then Education Minister and later Chief Minister of Uttar Pradesh, he established an astronomical observatory at Varanasi on April 20, 1954. Later on it was shifted to Manora Peak, Nainital. Four reflectors were commissioned at Manora Peak. For solar research an H alpha petrol unit and a horizontal solar spectrograph was setup. A detailed project report for installation of a 4-m class optical telescope was prepared indigenously in late 1980, however, the project could not take off. With the generous support of the Department of Science and Technology, the institute established a 3.6-m new technology optical telescope and a 1.3-m wide field optical telescope at a new observing site called Devasthal. Now a 4-m liquid mirror telescope is also being installed at the same observing site. I present here a brief journey of the observatory beginning right from its birth in 1954 till now.

description: We investigate the dynamics of a quantum particle in disordered tight-binding models in one and two dimensions which are exceptions to the common wisdom on Anderson localization, in the sense that the localization length diverges at some special energies. We provide a consistent picture for two well-known one-dimensional examples: the chain with off-diagonal disorder and the random-dimer model. In both cases the quantum motion exhibits a peculiar kind of anomalous diffusion which can be referred to as bi-fractality. The disorder-averaged density profile of the particle becomes critical in the long-time regime. The $q$-th moment of the position of the particle diverges with time whenever $q$ exceeds some $q_0$. We obtain $q_0=2$ for off-diagonal disorder on the chain (and conjecturally on two-dimensional bipartite lattices as well). For the random-dimer model, our result $q_0=1/2$ corroborates known rigorous results.

description: The interaction between two quantum bits enables entanglement, the two-particle correlations that are at the heart of quantum information science. In semiconductor quantum dots much work has focused on demonstrating single spin qubit control using optical techniques. However, optical control of entanglement of two spin qubits remains a major challenge for scaling from a single qubit to a full-fledged quantum information platform. Here, we combine advances in vertically-stacked quantum dots with ultrafast laser techniques to achieve optical control of the entangled state of two electron spins. Each electron is in a separate InAs quantum dot, and the spins interact through tunneling, where the tunneling rate determines how rapidly entangling operations can be performed. The two-qubit gate speeds achieved here are over an order of magnitude faster than in other systems. These results demonstrate the viability and advantages of optically controlled quantum dot spins for multi-qubit systems.

description: The value of the important triple-Pomeron coupling is estimated by an unorthodox procedure using the known diffractive parton distribution functions. The result is g_{3P}\simeq 0.2g_N, where g_N is the Pomeron-nucleon coupling. This is in excellent agreement with an independent determination, g_{3P}\simeq 0.2g_N, previously obtained by analysing the available data in the triple-Regge region with absorptive effects taken into account.

description: The upcoming 4-m International Liquid Mirror Telescope (ILMT) facility will perform deep imaging (in single scan g’~22 mag) of a narrow strip of sky each clear night in the Time Delayed Integration mode. A cadence of one day observation will provide unique opportunities to discover different types of supernovae (SNe) along with many other types of variable sources. We present the approach to discover SNe with the 4-m ILMT and discuss the follow-up strategy in the context of other existing observational facilities. The advantages of liquid mirror telescope observations over the traditional glass mirror telescopes are also discussed.
Constraining the star formation rate in the Solar neighbourhood with star clusters

description: This paper investigates the star formation rate (SFR) in the Solar neighbourhood. First, we build the local age distribution function (ADF) with an updated sample of 442 star clusters located at less than 1\,kpc from the Sun. Next, we define the SFR, compute the individual mass evolution of a population of artificial clusters covering the broad range of parameters observed in actual clusters, and assume 100\,\ms\ as the low-mass limit for effective cluster observation. This leads to a simulated ADF, which is compared to the low-noise Solar neighbourhood ADF. The best match corresponds to a non-constant SFR presenting two conspicuous excesses for ages $\le9$\,Myr and between 220-600\,Myr (the local starburst). The average formation rate is $\bar{SFR}\approx(2500\pm500)\,\mmy$, corresponding to the average surface formation rate $\bar{\ssfr}\approx(790\pm160)\,\mmk$. These values are consistent with the formation rate inferred from embedded clusters (ECs), but much lower ($\la16%$) than that implied by field stars. Both the local starburst and the recent star formation period require $SFR\sim2\times\bar{SFR}$ to be described. The simulations show that $91.2\pm2.7%$ of the clusters created in the Solar neighbourhood do not survive the first 10\,Myr, which is consistent with the rate of EC dissolution.

description: We discuss how to construct stable multidimensional extensions of one-dimensional dark solitons, the so-called soliton stripes, in two-species Bose-Einstein condensates in the immiscible regime. We show how using a second component to fill the core a dark soliton stripe leads to reduced instabilities while propagating in homogeneous media. We also discuss how in the presence of a trap arbitrarily long-lived dark soliton stripes can be constructed by increasing the filling of the dark stripe core. Numerical evidences of the robustness of the dark soliton stripes in collision scenarios are also provided.

description: The 4-m International Liquid Mirror Telescope (ILMT) located at the ARIES Observatory (Devasthal, India) has been designed to scan at a latitude of +29° 22’ 26” a band of sky having a width of about half a degree in the Time Delayed Integration (TDI) mode. Therefore, a special data-reduction and analysis pipeline to process online the large amount of optical data being produced has been dedicated to it. This requirement has led to the development of the 4-m ILMT data reduction pipeline, a new software package built with Python in order to simplify a large number of tasks aimed at the reduction of the acquired TDI images. This software provides astronomers with specially designed data reduction functions, astrometry and photometry calibration tools. In this paper we discuss the various reduction and calibration steps followed to reduce TDI images obtained in May 2015 with the Devasthal 1.3m telescope. We report here the detection and characterization of nine space debris present in the TDI frames.

description: M-dwarfs in extremely wide binary systems are very rare, and may thus have different formation processes from those found as single stars or close binaries in the field. In this paper we search for close companions to a new sample of 36 extremely wide M-dwarf binaries, covering a spectral type range of M1 to M5 and a separation range of 600 - 6500 AU. We discover 10 new triple systems and one new quadruple system. We carefully account for selection effects including proper motion, magnitude limits, the detection of close binaries in the SDSS, and other sample biases. The bias-corrected total high-order-multiple fraction is 45% (+18%/-16%) and the bias-corrected incidence of quadruple systems is < 5%, both statistically compatible with that found for the more common close M-dwarf multiple systems. Almost all the detected companions have similar masses to their primaries, although two very low mass companions, including a candidate brown dwarf, are found at relatively large separations. We find that the close-binary separation distribution is strongly peaked towards < 30AU separations. There is marginally significant evidence for a change in high-order M-dwarf multiplicity with binding energy and total mass. We also find 2-sigma evidence of an unexpected increased high-order-multiple fraction for the widest targets in our survey, with a high-order-multiple fraction of 21% (+17%/-7%) for systems with separations up to 2000AU, compared to 77% (+9%/-22%) for systems with separations > 4000AU. These results suggest that the very widest M-dwarf binary systems need higher masses to form or to survive.

description: High temporal resolution observations enable the study of rapid phenomena such as the flux varia¬tions in binary system objects, e.g. cataclysmic variables, compact binary systems, the flux variations in young star clusters, stellar occultations and more. The 2.4-m Thai National Telescope (TNT) is ideally suited for this niche research, being the largest facility in Southeast Asia and being equipped with ULTRASPEC, a high-speed imager based on a low-noise frame transfer electron-multiplying CCD. In the sub-window mode, ULTRASPEC can record uninterrupted sequences with frame rates as fast as few milliseconds. We present some of the key results obtained in the area of high time resolution with ULTRASPEC. We also present the results of a recent worldwide campaign to observe the current series of lunar occultations of Aldebaran (α Tauri) carried out in close collaboration with the Devasthal facilities, the out-of-eclipse variations on the post common-envelope system J1021+1744, and pre-main-sequence variables in young open cluster Stock 8.

description: Solar system astronomy would be an important field of study with the 3.6-m Devasthal Optical Telescope (DOT) and the 4-m International Liquid Mirror Telescope (ILMT). In this contribution, we highlight the work that could be done in reaching a better understanding of the Solar system and its constituents - particularly the minor bodies and other smaller objects. There may be a large number of very faint objects in the vicinity of the Earth orbit. In fact only recently a \'second moon\' of the Earth has been found and has been designated 2016 H03. This is a quasi-satellite with the same period of revolution around Earth and Sun. There could be many such objects and it is important to have a full characterization and understanding of these potentially hazardous objects. They are generally fainter than 18th magnitude and one would need a lot of telescope time to fully characterize these objects using techniques of spectropolarimetry. In a similar fashion, a deep census of the Kuiper Belt Objects and the TNOs is needed. In this census, the concept of pencil beam surveys could be extended to cylindrical transit imaging technique available with the 4-m ILMT.

Vapour phase partial oxidation of pyrolysis oil model compounds in presence of vanadia-titania catalyst
Creators: name: Ramachandran, Anuradha
Publisher: name: University of British Columbia
Year: 2021

description: Pyrolysis oil obtained from biomass has complex chemistry with more than 300 compounds. The utilization of pyrolysis oil as a transportation fuel is challenged by the high water and oxygen content in the pyrolysis oil. In this study, an alternate approach to improve the economic viability of pyrolysis oil is explored by employing oxidative catalysis to convert bio-oil ketones and alcohols to carboxylic acids. Due to bio-oil’s complex chemistry, this study examined two representative compounds from alcohol and ketone functional groups: ethanol (ETH) and hydroxyacetone (HAC). The model compounds were subjected to partial oxidation in presence of vanadium pentaoxide on titanium dioxide (V/TiO₂) support. The effect of temperature, oxygen ratio in the feed, and weight hourly space velocity (WHSV) on conversion, selectivity, and yield from the oxidation reaction were investigated in a packed bed reactor. Partial oxidation of HAC in presence of V/TiO₂ produced lactic acid, acetic acid, and formic acid. 92.8% conversion was achieved at 473K, O₂/HAC molar ratio = 1.5 at WHSV of 1100 cm³·min⁻¹·gcat⁻¹. Temperature, O₂/HAC and WHSV was found to impact the conversion of HAC and yield of LA. The overall reaction followed second-order kinetics and the activation energy was estimated to be 31.35 kJ·mol⁻¹. Acetic acid (AA), acetaldehyde, CO₂, and CO were identified as the major products from partial oxidation of ethanol in V/TiO₂ catalyst. Complete conversion of ETH was achieved at higher temperatures (>523K) and low WHSV conditions (<250 cm³·min⁻¹·gcat⁻¹). Only temperature and WHSV were identified as variables with significant influence on the conversion of ETH and yield of AA. A first-order rate law was used to describe overall kinetics and the activation energy was estimated to be 76.03kJ·mol⁻¹. The influence of acetic acid in the feed mixture was also investigated. The conversion of HAC and ETH in presence of acetic acid decreased slightly. However, the selectivity and yield of desired acids were similar to the reaction of aqueous HAC and ETH alone. This work successfully demonstrated the selective oxidation of model compounds with alcohol and ketone functional groups to carboxylic acid in presence of V/TiO₂ catalysts.

description: The terahertz spectra of the dynamic conductivity and radiation absorption coefficient in germanium-silicon heterostructures with arrays of Ge hut clusters (quantum dots) have been measured for the first time in the frequency range of 0.3-1.2 THz at room temperature. It has been found that the effective dynamic conductivity and effective radiation absorption coefficient in the heterostructure due to the presence of germanium quantum dots in it are much larger than the respective quantities of both the bulk Ge single crystal and Ge/Si(001) without arrays of quantum dots. The possible microscopic mechanisms of the detected increase in the absorption in arrays of quantum dots have been discussed.

description: This brief review discusses electronic properties of mesoscopic graphene-based structures. These allow controlling the confinement and transport of charge and spin; thus, they are of interest not only for fundamental research, but also for applications. The graphene-related topics covered here are: edges, nanoribbons, quantum dots, $pn$-junctions, $pnp$-structures, and quantum barriers and waveguides. This review is partly intended as a short introduction to graphene mesoscopics.
