Geology and mineralization at Independence Creek : Dawson Range, West-central Yukon Territory
Creators: name: McKenzie, Greg
Publisher: name: University of British Columbia
Year: 2014

description: The Independence Creek (“Boulevard”) area in the Dawson Range district in west-central Yukon has recently received new government geological mapping; however, little is known about the nature or origin of gold mineralization in this region. A regional metallogenic framework for the mineralization is proposed herein, based on geological, structural, geochronological, and fluid inclusion studies. The study area is underlain by Paleozoic metamorphic rocks of the Yukon-Tanana terrane and is flanked to the north by the mid-Cretaceous Coffee Creek plutonic suite, a phase of the Dawson Range batholith to the southwest. Two separate but related mineralizing systems have been identified within the study area: the Sunset Trend, a gold exploration target, and the Toni Tiger molybdenite occurrence. Gold mineralization in the Sunset Trend is hosted in a chlorite-biotite ± actinolite schist along brittle northwest-trending structures. The highest gold grades are associated with fault zones, locally including vein breccia, that are dominated by iron-rich clay gouge. The main rock type at the Toni Tiger occurrence is a diopside-garnet skarn that is cross-cut by quartz-molybdenite veins which commonly trend northeast. Fluid inclusion studies indicate that mineralization in both systems formed from similar H₂O-CO₂-NaCl type fluids at conditions >280°C and 1100bar. ⁴⁰Ar/³⁹Ar dating of post-metamorphic hydrothermal sericite yielded an approximate age for mineralization in the Sunset Trend of 95Ma, which overlaps within error with the 95.0 ± 0.4Ma Re-Os age obtained from molybdenite at Toni Tiger. Both of these ages are significantly younger than nearby intrusions, suggesting that mineralization is not directly related to the intrusions. The Independence Creek gold system is interpreted to have formed in zones of dilation that related to an overall dextral strike slip system that developed following the emplacement of the Coffee Creek granite at ~99Ma. Geological and geochronological evidence suggests that the Independence Creek mineralization, together with the Longline deposit located 75km to the northwest, and possibly part of the Coffee gold system located in the Coffee Creek plutonic suite, are products of a mid-Cretaceous, post-magmatic orogenic event that occurred between 96 and 92Ma, during the exhumation of the Dawson Range batholith.

description: We report an investigation of perovskite-type LaNiO3 thin films by Raman scattering in both various scattering configurations and as a function of temperature. The room-temperature Raman spectra and the associated phonon mode assignment provide reference data for phonon calculations and for the use of Raman scattering for structural investigations of LaNiO3, namely the effect of strain in thin films or heterostructures. The temperature-dependent Raman spectra from 80 to 900 K are characterized by the softening of the rotational A1g mode, which suggest a decreasing rhombohedral distortion towards the ideal cubic structure with increasing temperature.
Metal-insulator transition induced by fluctuations of the magnetic potential in semiconductors with magnetic impurities

description: We investigate the metal-insulator transition occurring in semiconductors with magnetic impurities when lowering temperature. In contrast to the usually considered percolation transition in the non-uniform medium induced by the localization of charge carriers in the fluctuating \emph{electric} potential, the studied transition is connected with their localization in the fluctuating \emph{magnetic} potential produced by magnetized impurities (more accurately - in the combined fluctuating potential). When decreasing temperature, the magnetization of magnetic impurities in the semiconductor becomes higher and even at the invariable (temperature independent) amplitude of the electric potential, the magnetic component of the total potential increases. With increasing fluctuation amplitude, the Fermi level of charge carriers sinks deeper and deeper into the growing tail of density of states until it falls under the percolation level. For that, fluctuations of the total potential have to run up to some critical value. On reaching that value, the transition occurs from the metal conductivity to the activation one (the metal-insulator transition).

description: The Nuclear Compton Telescope (NCT) is a balloon-borne Compton telescope designed for the study of astrophysical sources in the soft gamma-ray regime (200 keV--20 MeV). NCT's ten high-purity germanium crossed-strip detectors measure the deposited energies and three-dimensional positions of gamma-ray interactions in the sensitive volume, and this information is used to restrict the initial photon to a circle on the sky using the Compton scatter technique. Thus NCT is able to perform spectroscopy, imaging, and polarization analysis on soft gamma-ray sources. NCT is one of the next generation of Compton telescopes --- so-called compact Compton telescopes (CCTs) --- which can achieve effective areas comparable to COMPTEL's with an instrument that is a fraction of the size. The Crab Nebula was the primary target for the second flight of the NCT instrument, which occurred on 17--18 May 2009 in Fort Sumner, New Mexico. Analysis of 29.3 ks of data from the flight reveals an image of the Crab at a significance of 4-sigma. This is the first reported detection of an astrophysical source by a CCT.

description: We present the results of two NuSTAR observations of the recently discovered source MAXI J1848-015. The source underwent a period of outburst which lasted only around 10 days, during which it showed evidence, including a strong thermal component and broad Fe emission features, for a hot accretion disk which extended to the innermost stable circular orbit around the central accretor. However the observed flux indicated an Eddington fraction of at most ~10^-3. In this luminosity regime, disk accretion near the central object is not expected. We discuss possible scenarios which may lead to this behavior. We also show evidence for a high spin parameter, possibly indicating that the accretor is a black hole, and for disk truncation in the hard state.

description: Magnetic nanowires are a good platform to study fundamental processes in Magnetism and have many attractive applications in recording such as perpendicular storage and in spintronics such as non-volatile magnetic memory devices (MRAM) and magnetic logic devices. In this work, nanowires are used to study magnetization reversal processes through a novel geometric approach. Reversal modes imprint a definite signature on a parametric curve representing the locus of the critical switching field. We show how the different modes affect the geometry of this curve depending on the nature of the anisotropy (uniaxial or cubic anisotropy), demagnetization and exchange effects. The samples we use are electrochemically grown Nickel and Cobalt nanowires.

Bloch oscillations in tight-binding lattices with defects

Year: 2010
Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: Defects in tight-binding lattices generally destroy the onset of Bloch oscillations (BOs) and the periodic self-imaging of the wave packet due to the lack of an equally-spaced Wannier-Stark ladder spectrum. Here it is shown that localized and extended defects in the lattice can be engineered to be transparent for BOs. Such lattices are synthesized from the defect-free lattice by the technique of intertwining operators generally employed in supersymmetric quantum mechanics. The energy spectrum of the synthesized lattices differs from the Wannier-Stark ladder of the defect-free lattice because of the missing of pairs of resonances in the ladder, thus ensuring the persistence of BOs.

 Taxonomical notes. Alona s. lato is artificial group, which is currently actively revised (Van Damme & Dumont 2008ab; Van Damme et al. 2010, 2011; Sinev 2015; Sinev & Dumont 2016; Sousa et al. 2016 and others). Most species-groups of Alona s. lato were already transferred into separate genera. Of species recorded in the region, Alona archeri and A. cambouei were replaced to the genus Ovalona (Sinev, 2015); Alona costata and A. cheni to the genus Flavalona (Sinev & Dumont, 2016); Alona diaphana to the genus Leberis (Sinev et al., 2005); Alona freyi to the genus Matralona (Sinev & Kotov 2012); Alona macronyx to the genus Celsinotium (Sinev & Kotov 2012); Alona sarasinorum to the genus Salinalona (Van Damme & Maiphae, 2013); Alona siamensis tho the genus Magnospina (Sousa et al. 2016); and Alona of verrucosa -group to the genus Anthalona (Van Damme et al. 2011).
 Still, taxonomic status of many forms is still not clear, and they are included here in Alona s. lato. Only one South-East Asian species, A. kotovi, belongs to Alona s. str., which includes only species of quadrangularis -group (Sinev, 2012).

description: We report on the effects of quantum interference induced by transmission of an arbitrary number of optical quantum states through a multiple scattering medium. We identify the role of quantum interference on the photon correlations and the degree of continuous variable entanglement between two output modes. It is shown that the effect of quantum interference survives averaging over all ensembles of disorder and manifests itself as increased photon correlations giving rise to photon anti-bunching. Finally, the existence of continuous variable entanglement correlations in a volume speckle pattern is predicted. Our results suggest that multiple scattering provides a promising way of coherently interfering many independent quantum states of light of potential use in quantum information processing.

description: Swift J0840.7-3516 is an X-ray transient discovered with Swift/BAT in 2020 February. We investigated its X-ray properties using extensive data from Swift, MAXI, NICER, and NuSTAR. The source flux increased for ~10^3 s after the discovery, decayed rapidly over ~5 orders of magnitude in five days, and then remained almost constant over nine months. Large-amplitude short-term variations on timescales of 1-10^4 s were observed throughout the decay. In the initial flux rise, the source showed a hard power-law-shaped spectrum with a photon index of ~1.0 extending up to ~30 keV, above which an exponential cutoff was present. The photon index increased in the following rapid decay and became ~2 at the end of the decay. A spectral absorption feature at 3-4 keV was detected in the decay. It is not straightforward to explain all the observed properties by any known class of X-ray sources. We discuss the possible nature of the source, including a Galactic low-mass X-ray binary with multiple extreme properties.

description: We observed M51 at three frequencies, 1.4GHz (20cm), 4.9GHz (6cm) and 8.4GHz (3.6cm), with the VLA and the Effelsberg 100m telescope to obtain the highest quality radio continuum images of a nearby spiral galaxy. These radio data were combined with deconvolved Spitzer IRAC 8mum and MIPS 24mum images to search for and investigate local changes in the radio-IR correlation. Utilizing wavelet decomposition, we compare the distribution of the radio and IR emission on spatial scales between 200pc and 30kpc. We show that the radio-IR correlation is not uniform across the galactic disk. It presents a complex behavior with local extrema corresponding to various galactic structures, such as complexes of HII regions, spiral arms and interarm filaments, indicating that the contribution of the thermal and non-thermal radio emission is a strong function of environment. In particular, the relation of the 24mum and 20cm emission presents a linear relation within the spiral arms and globally over the galaxy, while it deviates from linearity in the interarm and outer regions as well in the inner region, with two different behaviours: it is sublinear in the interarm and outer region and over-linear in the central 3.5kpc. Our analysis suggests that the changes in the radio/IR correlation reflect variations of ISM properties between spiral arms and interarm region. The good correlation in the spiral arms implies that 24mum and 20cm are tracing recent star formation, while a change in the dust opacity, 'Cirrus' contribution to the IR emission and/or the relation between the magnetic field strength and the gas density can explain the different relations found in the interarm, outer and inner regions.

On Optimal Allocation of a Continuous Resource Using an Iterative Approach and Total Positivity

description: We study a class of optimal allocation problems, including the well-known Bomber Problem, with the following common probabilistic structure. An aircraft equipped with an amount~$x$ of ammunition is intercepted by enemy airplanes arriving according to a homogenous Poisson process over a fixed time duration~$t$. Upon encountering an enemy, the aircraft has the choice of spending any amount~$0\le y\le x$ of its ammunition, resulting in the aircraft's survival with probability equal to some known increasing function of $y$. Two different goals have been considered in the literature concerning the optimal amount~$K(x,t)$ of ammunition spent: (i)~Maximizing the probability of surviving for time~$t$, which is the so-called Bomber Problem, and (ii) maximizing the number of enemy airplanes shot down during time~$t$, which we call the Fighter Problem. Several authors have attempted to settle the following conjectures about the monotonicity of $K(x,t)$: [A] $K(x,t)$ is decreasing in $t$, [B] $K(x,t)$ is increasing in $x$, and [C] the amount~$x-K(x,t)$ held back is increasing in $x$. [A] and [C] have been shown for the Bomber Problem with discrete ammunition, while [B] is still an open question. In this paper we consider both time and ammunition continuous, and for the Bomber Problem prove [A] and [C], while for the Fighter we prove [A] and [C] for one special case and [B] and [C] for another. These proofs involve showing that the optimal survival probability and optimal number shot down are totally positive of order 2 ($\mbox{TP}_2$) in the Bomber and Fighter Problems, respectively. The $\mbox{TP}_2$ property is shown by constructing convergent sequences of approximating functions through an iterative operation which preserves $\mbox{TP}_2$ and other properties.

description: In this paper we found an Exact solution for massless scalar field with cosmological constant. This exact solution generalized the Levi-Civita vacuum solution\cite{8} to a massless scalar field,with a cosmological constant term. This solution in the absence of the Cosmological constant recovers the spacetime of a massless scalar field with cylindrical symmetry (\emph{Buchdahl metric}\cite{2}). Also if the scalar field disappears, the spacetime is a representation of de-Sitter space. We prove that the form of the metric's function which was purposed in \cite{1} is valid even if we assume a general form. Too we show that in which conditions this solution satisfies energy conditions. Finally the validity of focusing theorem is proved.

Otherworlds : teachers' experiences of power vis à vis accountability policies in South Carolina
Creators: name: Adkins Cartee, Mary Rebecca
Publisher: name: University of British Columbia
Year: 2014

description: This study focuses on a single school district as a site of concept-building in relation to teachers’ subjective experiences of power vis à vis a neoliberal policy regime. The assemblage of teachers’ subjectivities takes place in the context of the Southeastern United States, in a policy environment highly influenced by neoliberal ideology. The study focuses on the South Carolina School Report Card Policy (part of No Child Left Behind) as an instantiation of neoliberal education policy and draws on a Foucauldian and Deleuzian framework for understanding how power produces teachers’ subjectivities with and through policy. The researcher orients this work as a fieldwork in philosophy in order to think about power with teachers in the situated contexts of their lives in a unique school district; this study therefore generalizes to theory rather than to people or location. The research concludes that power a/effected teachers’ subjectivities through disciplinary technologies and the creation and maintenance of affective channels, having bodily and material impacts on teachers, and causing them to find ‘the other’ of students’ bodies, which have been raced, classed, and gendered, in themselves.

description: Recommender systems are promising ways to filter the overabundant information in modern society. Their algorithms help individuals to explore decent items, but it is unclear how they allocate popularity among items. In this paper, we simulate successive recommendations and measure their influence on the dispersion of item popularity by Gini coefficient. Our result indicates that local diffusion and collaborative filtering reinforce the popularity of hot items, widening the popularity dispersion. On the other hand, the heat conduction algorithm increases the popularity of the niche items and generates smaller dispersion of item popularity. Simulations are compared to mean-field predictions. Our results suggest that recommender systems have reinforcing influence on global diversification.

Safe sleep, day and night: the experiences of parents regarding infant sleep safety

description: Sudden infant death syndrome (SIDS) is the third leading cause of death for British Columbian infants younger than one year of age. Sudden unexplained infant death (SUID) is increasing in British Columbia and is linked to unsafe sleep environments. Although guidelines on how to place infants to sleep safely have been developed, no Canadian studies and a paucity of qualitative studies have explored the views and experiences of the parents regarding infant sleep safety. I used a qualitative description design to obtain 14 mothers’ experiences with infant sleep safety. The mothers resided in the Greater Vancouver region. The development of the core theme, the Mothers’ Infant Sleep Safety Cycle, described mothers’ experiences with infant sleep safety as a cyclical and continuous process from the prenatal period and throughout the first six months of their infants’ lives and beyond. There are five segments in this cyclical process: mothers’ expectations of sleep safety, struggles with reality as opposed to maternal visions, modifications of expectations, provisions of rationale for choices and developmental shifts in views of capabilities. Despite mothers’ awareness of the risk of SIDS and SUID and their original intentions to adhere to the sleep safety guidelines, mothers felt compelled to modify their infants’ sleeping arrangements as they struggled with infants’ sleeping and crying challenges, as well as their own sleep deprivation. Mothers’ experiences with infant sleep safety were influenced by four primary factors: perceptions of everyone’s needs, familial influences, attitudes and judgments from outsiders, and resource availability and accessibility. Based on the study findings I suggested nursing implications for clinical practice, education and research starting in the prenatal period and into the postnatal period, in terms of supporting and assisting mothers in implementing plans to follow sleep safety principles while managing their infants’ sleeping and crying challenges as well as their own sleep deprivation, day and night.

description: The Bomber Problem concerns optimal sequential allocation of partially effective ammunition $x$ while under attack from enemies arriving according to a Poisson process over a time interval of length $t$. In the doubly-continuous setting, in certain regions of $(x,t)$-space we are able to solve the integral equation defining the optimal survival probability and find the optimal allocation function $K(x,t)$ exactly in these regions. As a consequence, we complete the proof of the "spend-it-all" conjecture of Bartroff et al. (2010b) which gives the boundary of the region where $K(x,t)=x$.

description: All codes with minimum distance 8 and codimension up to 14 and all codes with minimum distance 10 and codimension up to 18 are classified. Nonexistence of codes with parameters [33,18,8] and [33,14,10] is proved. This leads to 8 new exact bounds for binary linear codes. Primarily two algorithms considering the dual codes are used, namely extension of dual codes with a proper coordinate, and a fast algorithm for finding a maximum clique in a graph, which is modified to find a maximum set of vectors with the right dependency structure.

description: Negatively charged Nitrogen-Vacancy (NV$^-$) centers in diamond produced by ion implantation often show properties different from NVs created during the crystal growth. We observe that NVs created from nitrogen ions with four different energies (30-300 keV) show much shorter electron spin coherence time $T_2$ compared to the "natural" NVs and we could find any dependence of $T_2$ on the implantation energy. Moreover, we also find out that about 10% of them show switching from NV$^-$to NV$^0$. We develop a method to increase $T_2$ of single NV$^-$ centers by annealing the sample at $t=1200 {\circ}$C whereas at the same time the fraction of the NVs showing discharging is greatly reduced.

description: The positions of nucleosomes in eukaryotic genomes determine which parts of the DNA sequence are readily accessible for regulatory proteins and which are not. Genome-wide maps of nucleosome positions have revealed a salient pattern around transcription start sites, involving a nucleosome-free region (NFR) flanked by a pronounced periodic pattern in the average nucleosome density. While the periodic pattern clearly reflects well-positioned nucleosomes, the positioning mechanism is less clear. A recent experimental study by Mavrich et al. argued that the pattern observed in S. cerevisiae is qualitatively consistent with a `barrier nucleosome model', in which the oscillatory pattern is created by the statistical positioning mechanism of Kornberg and Stryer. On the other hand, there is clear evidence for intrinsic sequence preferences of nucleosomes, and it is unclear to what extent these sequence preferences affect the observed pattern. To test the barrier nucleosome model, we quantitatively analyze yeast nucleosome positioning data both up- and downstream from NFRs. Our analysis is based on the Tonks model of statistical physics which quantifies the interplay between the excluded-volume interaction of nucleosomes and their positional entropy. We find that although the typical patterns on the two sides of the NFR are different, they are both quantitatively described by the same physical model, with the same parameters, but different boundary conditions. The inferred boundary conditions suggest that the first nucleosome downstream from the NFR (the +1 nucleosome) is typically directly positioned while the first nucleosome upstream is statistically positioned via a nucleosome-repelling DNA region. These boundary conditions, which can be locally encoded into the genome sequence, significantly shape the statistical distribution of nucleosomes over a range of up to ~1000 bp to each side.

GET UP – COOL DOWN. Entwicklung und Evaluation eines Online-Trainings zur Selbstführung mit Fokus auf die Komponente der Selbstberuhigung
Creators: name: Inauen, Corinna
Year: 2021

description: Der rasche Wandel in der modernen Arbeitswelt sowie der rasante Anstieg der Arbeit im Homeoffice durch die aktuelle COVID-19-Pandemie zeigen die Dringlichkeit auf, Interventionen zur Bewältigung der damit einhergehenden Herausforderungen zu implementieren. Ziel der vorliegenden Studie war es daher, ein Online-Training zur Selbstführung mit dem Fokus auf die Kompetenz der Selbstberuhigung zu entwickeln und evaluieren. Das Training wurde basierend auf theoretischen Erkenntnissen zur Regulierung negativer Affekte erstellt, welche unter anderem der PSI-Theorie nach Kuhl, dem Selbstregulationsmodell nach Wieland und Baggen, dem Stressmodell nach Lazarus sowie der Forschung zu psychologischem Detachment entnommen wurden. Die Wirksamkeit des Trainings wurde abhängig von der konkreten Forschungsfrage mit einer Stichprobe von mindestens 120 Teilnehmer*innen überprüft. Die Teilnehmer*innen wurden unter Voraussetzung eines Mindestalters von 18 Jahren und Erfahrung im Homeoffice rekrutiert und randomisiert der Interventions- oder Wartekontrollgruppe zugewiesen. Letztere erhielt im gesamten Zeitraum der Studie kein Training. Für die Untersuchung wurde ein Pre-Post-Follow-Up Design gewählt. Dementsprechend wurden die Daten zeitgleich in beiden Gruppen via Online-Befragung vor Beginn des Trainings, nach dem vierwöchigen Training und nach einer anschließenden zweiwöchigen Trainingspause erhoben. Mittels zweier ANCOVAs und einem t-Test für abhängige Stichproben konnte ein kleiner, kurzfristiger Trainingseffekt sowie eine Stabilität der Selbstberuhigungswerte zwischen der Post- und Follow-Up-Erhebung gefunden werden, jedoch kein Langzeiteffekt. Die Ergebnisse können daher als Unterstützung zur theoretischen Konzeption und praktischen Umsetzung für die Erstellung von Online-Selbstführungstrainings dienen und sollten durch weitere Forschung ergänzt werden, um das Training zur Erreichung eines langfristigen Trainingseffekts anzupassen.

 Parthenogenetic female short description. Body low to moderately high, oval; head and valves with a welldefined keel in all Old World species (Fig. 7 D). Sculpture of valves as longitudinal lines. Posteroventral angle of valves with or without denticles. Rostrum triangular in lateral view, with a pointed or blunt apex. Three main head pores with narrow connection between them, located at widened part of head keel. Lateral head pores minute. Labral keel of moderate width, with rounded or blunt apex, with clusters of setulae on posterior margin.
Postabdomen very long and narrow, with narrowing distally in postanal part; length about 5–6 heights (Fig. 7 E, G). Preanal angle weakly defined, postanal angle not defined. Postanal denticles of variable shape. Postanal lateral groups of short setulae; in distalmost groups, length of setulae less than the width of base of postabdominal claw. Postabdominal claw long, almost straight, with short basal spine. A prominent spine or pecten of spines located at the middle of the claw.
Antennule without lateral aesthetascs; two of terminal aesthetascs much longer than others. Antennal seta without basal peg. Antenna without a seta on basal segment of endopod. Spine on basal segment of exopodite less than 1/4 length of middle segment. Spines on apical segments less than about 1/3 length of apical segments. IDL of limb I with three setae of variable morphology.
 Taxonomic notes: two species recorded in the region, C. vietnamensis and C. uncinatus, are very close to each other in external morphology and morphology of appendages. The species can be recognized only by careful examination of postabdomen armament, they also differ in size. Many earlier records of Camptocercus from South- East Asia, including one of Idris (1983) were attributed to Camptocercus australis Sars, 1896 but this species is not present in the region.

The effects of substrate brightness and complexity on intertidal communities of seawalls

description: The marine environment is being increasingly urbanized at the expense of biodiversity. Increased interest in ecological engineering to mitigate this loss of biodiversity has involved introducing habitat complexity to marine infrastructure, however other factors have been largely overlooked, such as substrate brightness, which can affect species colonisation and thermal absorption. Concrete panels, with different complexities and brightness treatments, were affixed to seawalls in Sydney Harbour to investigate how habitat complexity and substrate brightness influences intertidal communities and how these effects change with respect to tidal elevation. I hypothesised that the effects of habitat complexity would strengthen across a passive warming gradient created by decreasing brightness, with greater levels of colonisation when complexity was present. Overall, effects of habitat complexity and substrate brightness were largely independent of each other, with some exceptions, and varied greatly by site. Substrate brightness influenced colonisation initially, with generally greater colonisation on white panels, but its effects diminished over time, with effects of habitat complexity instead growing stronger. Abundance and richness were greater on complex than flat panels. The strength of these effects varied across sites, and tidal elevations, indicating the need to match eco-engineering interventions to site conditions in order to achieve ecological benefit.
