description: A poorly understood step in the transition from a chemical to a biological world is the emergence of self-replicating molecular systems. We study how a precursor for such a replicator might arise in a hydrothermal RNA reactor, which accumulates longer sequences from unbiased monomer influx and random ligation. In the reactor, intra- and inter-molecular basepairing locally protects from random cleavage. By analyzing stochastic simulations, we find temporal sequence correlations that constitute a signature of information transmission, weaker but of the same form as in a true replicator.

description: The ability to efficiently and accurately detect objects plays a very crucial role for many computer vision tasks. Recently, offline object detectors have shown a tremendous success. However, one major drawback of offline techniques is that a complete set of training data has to be collected beforehand. In addition, once learned, an offline detector can not make use of newly arriving data. To alleviate these drawbacks, online learning has been adopted with the following objectives: (1) the technique should be computationally and storage efficient; (2) the updated classifier must maintain its high classification accuracy. In this paper, we propose an effective and efficient framework for learning an adaptive online greedy sparse linear discriminant analysis (GSLDA) model. Unlike many existing online boosting detectors, which usually apply exponential or logistic loss, our online algorithm makes use of LDA's learning criterion that not only aims to maximize the class-separation criterion but also incorporates the asymmetrical property of training data distributions. We provide a better alternative for online boosting algorithms in the context of training a visual object detector. We demonstrate the robustness and efficiency of our methods on handwriting digit and face data sets. Our results confirm that object detection tasks benefit significantly when trained in an online manner.

Peer language socialization in an internationalized study abroad context : norms for talking about language
Creators: name: Surtees, Victoria
Publisher: name: University of British Columbia
Year: 2018

description: Study abroad (SA) students often expect to have opportunities to interact with peers in the target language during their sojourns. However, while SA students report valuing peer relationships, to date, few studies have explored the role of peer interaction in SA (McGregor, 2016) and even less research has attended to peers’ perceptions of their role in SA students’ language learning (Kinginger, 2017). To address this gap, this qualitative multiple case study investigates peer language socialization at an internationalized English-medium university in Canada. It focuses on how language (e.g., grammar, use, lexis, and pronunciation) and language learning were oriented to in peers’ conversations, and the norms around how such topics were to be managed in informal talk. The focal students were three Japanese undergraduate SA students, each of whom recruited several English-speaking peers with whom they recorded weekly conversations. The data, which included interviews with peers and SA students as well as the recorded conversations, were analyzed using micro-analytic approaches, including membership categorization analysis (Housley & Fitzgerald, 2015; Sacks, 1992) and discursive approaches to stancetaking (Du Bois, 2007; Stevanovic & Peräkylä, 2012). Findings show that SA students had difficulty forming peer relationships, despite their engagement in extracurricular activities. The interview data also reveal that SA students valued peers who were multilingual and had experience with international students, and that peers valued SA students who asked for language help and displayed willingness to improve their English. While peers’ reports in interviews depicted discussions of language as relatively simple interactions, analyses of the peer interaction data demonstrated that SA students and peers required significant linguistic resources and prior knowledge to successfully engage in talk-about-language (Levine, 2009) and that not all SA students’ requests for language help were successful. These findings point to how “doing novice” and “doing expert” may be learned practices and highlight the need to conceive of peers as historical multifaceted individuals who may or may not be willing or able to appropriately “do expert” in interaction with SA students. As such, this study makes a significant contribution to applied linguistics in the areas of SA, peer interaction, and language socialization.

description: We use spin-resolved electron tunneling to study the exchange field in the Al component of EuS/Al bilayers, in both the superconducting and normal-state phases of the Al. Contrary to expectation, we show that the exchange field, Hex, is a non-linear function of applied field, even in applied fields that are well beyond the EuS coercive field. Furthermore the magnitude Hex is unaffected by the superconducting phase. In addition, Hex decreases significantly with increasing temperature in the temperature range of 0.1-1 K. We discuss these results in the context of recent theories of generalized spin-dependent boundary conditions at a superconductor/ferromagnet interface.

description: Abstract
The purpose of this study is to analyze: 1) Why are there juridical problems with the authority of the National Police and Bakamla in law enforcement in Indonesian sea areas? 2) What is the ideal construction in overcoming the Juridical Problems of the Authority of the National Police and Bakamla in Law Enforcement in Indonesian Sea Areas in the future?. The research method used is normative juridical with a statutory approach, concept approach, and case studies. The results showed that: 1) Regulations that regulate all aspects in the marine sector in Indonesia, and one of the impacts of many of these regulations is the overlapping authority of related agencies. u there are three agencies authorized in fisheries law enforcement based on Article 73 of Law No. 45 of 2009, namely the Ministry of Marine Affairs and Fisheries (MMAF), TNI Navy and Polri and Bakamla. However, this Law does not provide for a clear division of authority and a definite working mechanism. So that the three agencies have the same authority in enforcing fisheries law without any integration of the implementation system. This saves the potential for conflicts of authority, because all three have the authority to handle the same case, for example in terms of investigating and filing BAP and credit cards, contracts for shipping goods (land, sea and air, and so on. 2) to overcome the problems that occur between the National Police and Bakamla in law enforcement, they must look at the authority of each institution based on the law so that there is no misunderstanding in taking Law enforcement and coordination between law enforcement agencies is required.

In February, cyber adversaries escalated their MITM tactics by exploiting unsecured public Wi-Fi, ARP spoofing on local networks, and DNS vulnerabilities to redirect traffic to malicious sites, while session hijacking, rogue access points, and email interception further compromised sensitive data and credentials. Robust countermeasures—such as using VPNs, enforcing multi-factor authentication, employing encrypted protocols, and securing DNS—remain essential to safeguard our digital environments.

description: An unexpected feature of Titan's atmosphere is the strong depletion in primordial noble gases revealed by the Gas Chromatograph Mass Spectrometer aboard the Huygens probe during its descent on 2005 January 14. Although several plausible explanations have already been formulated, no definitive response to this issue has been yet found. Here, we investigate the possible sequestration of these noble gases in the liquid contained in lakes and wet terrains on Titan and the consequences for their atmospheric abundances. Considering the atmosphere and the liquid existing on the soil as a whole system, we compute the abundance of each noble gas relative to nitrogen. To do so, we make the assumption of thermodynamic equilibrium between the liquid and the atmosphere, the abundances of the different constituents being determined via {\bf } regular solution theory. We find that xenon's atmospheric depletion can be explained by its dissolution at ambient temperature in the liquid presumably present on Titan's soil. In the cases of argon and krypton, we find that the fractions incorporated in the liquid are negligible, implying that an alternative mechanism must be invoked to explain their atmospheric depletion.

description: During fabrication and scanning-tunneling-microscope (STM) imaging of dangling bonds (DBs) on a hydrogenated silicon surface, we consistently observed halo-like features around isolated DBs for specific imaging conditions. These surround individual or small groups of DBs, have abnormally sharp edges, and cannot be explained by conventional STM theory. Here we investigate the nature of these features by a comprehensive 3-dimensional model of elastic and inelastic charge transfer in the vicinity of a DB. Our essential finding is that non-equilibrium current through the localized electronic state of a DB determines the charging state of the DB. This localized charge distorts the electronic bands of the silicon sample, which in turn affects the STM current in that vicinity causing the halo effect. The influence of various imaging conditions and characteristics of the sample on STM images of DBs is also investigated.

description: Abstract
Making models of oil fields and performing the calculations of fields development of the reservoirs basins and systematic reservoirs are considered as quality ideas on the process of oil and gas exploration from the lower layers. The engineer in charge is responsible to calculate the development of an oil field based on individual concepts resulted from geological- geo-physical and hydrodynamic studies of wells. The main parameters include relative permeability, pressure gauge and indices of static and dynamic information production of reservoirs.The graph of gas to oil ratio illustrates that production is increased from the initial value as the oil production flow is enhanced.By reducing the flow of oil production, the ratio of gas to oil can be returned to its original level. Production water cutting diagram indicates that water cutting rate is rapidly increased through increasing oil production flow. In Yadavaran oil field, Hosseinieh anticline on Fahlian have been discovered by geophysical surveys. The drilling process of wells and reservoir simulation is a three-dimensional static and dynamic one. The Eclips and Petrol software was applied to do the segmental model from the model of the whole understudy field.In the north of Yadavaran oil field, wells 29, 28, 27, 26 have been created as future wells to produce more oil in the future due to the situation of oil, gas and water.

description: A key result of hydrogravitational dynamics cosmology relevant to astrobiology is the early formation of vast numbers of hot primordial-gas planets in million-solar-mass clumps as the dark matter of galaxies and the hosts of first life. Photon viscous forces in the expanding universe of the turbulent big bang prevent fragmentations of the plasma for mass scales smaller than protogalaxies. At the plasma to gas transition 300,000 years after the big bang, the 10^7 decrease in kinematic viscosity ν explains why ~3x10^7 planets are observed to exist per star in typical galaxies like the Milky Way, not eight or nine. Stars form by a binary accretional cascade from Earth-mass primordial planets to progressively larger masses that collect and recycle the stardust chemicals of life produced when stars overeat and explode. The astonishing complexity of molecular biology observed on Earth is possible to explain only if enormous numbers of primordial planets and their fragments have hosted the formation and wide scattering of the seeds of life virtually from the beginning of time. Geochemical and biological evidence suggests that life on Earth appears at the earliest moment it can survive, in highly evolved forms with complexity requiring a time scale in excess of the age of the galaxy. This is quite impossible within standard cold-dark-matter cosmology where planets are relatively recent, rare and cold, completely lacking mechanisms for intergalactic transport of life forms.

Algorithms for large-scale multi-codebook quantization

Publisher: name: University of British Columbia

description: Combinatorial vector compression is the task of expressing a set of vectors as accurately as possible in terms of discrete entries in multiple bases. The problem is of interest in the context of large-scale similarity search, as it provides a memory-efficient, yet ready-to-use compact representation of high-dimensional data on which vector similarities such as Euclidean distances and dot products can be efficiently approximated. Combinatorial compression poses a series of challenging optimization problems that are often a barrier to its deployment on very large scale systems (e.g., of over a billion entries). In this thesis we explore algorithms and optimization techniques that make combinatorial compression more accurate and efficient in practice, and thus provide a practical alternative to current methods for large-scale similarity search.

Such kind of variational problems were considered by Euler himself and have been recently investigated in [Methods Appl. Anal. 15 (2008), no. 4, 427-435]. Our results not only provide a generalization to previous results, but also give some other interesting optimality conditions as special cases.

description: Evolution is the fundamental physical process that gives rise to biological phenomena. Yet it is widely treated as a subset of population genetics, and thus its scope is artificially limited. As a result, the key issues of how rapidly evolution occurs, and its coupling to ecology have not been satisfactorily addressed and formulated. The lack of widespread appreciation for, and understanding of, the evolutionary process has arguably retarded the development of biology as a science, with disastrous consequences for its applications to medicine, ecology and the global environment. This review focuses on evolution as a problem in non-equilibrium statistical mechanics, where the key dynamical modes are collective, as evidenced by the plethora of mobile genetic elements whose role in shaping evolution has been revealed by modern genomic surveys. We discuss how condensed matter physics concepts might provide a useful perspective in evolutionary biology, the conceptual failings of the modern evolutionary synthesis, the open-ended growth of complexity, and the quintessentially self-referential nature of evolutionary dynamics.

description: Data on the photoproduction of omega mesons on nuclei have been re-analyzed in search for in-medium modifications. The data were taken with the Crystal Barrel(CB)/TAPS detector system at the ELSA accelerator facility in Bonn. The extracted omega line shape was found to be sensitive to the background subtraction. In experiments at the tagged photon facility of the Mainz MAMI accelerator photoproduction of mesons from light nuclear targets (deuteron and 3He) has been studied. The experiments used the combined Crystal Ball/TAPS setup in Mainz. Measurements of eta- and pi0-photoproduction off a liquid 3He-target have been used for the search for the formation of eta-mesic 3He. The installation of the WASA detector at COSY opened a unique possibility to search for the 4He-eta bound state with high statistics and high acceptance. We are conducting a search via an exclusive measurement of the excitation function for the dd -> 3He p pi- reaction.

description: With the unique database from Michelson Doppler Imager aboard the Solar and Heliospheric Observatory in an interval embodying solar cycle 23, the cyclic behavior of solar small-scale magnetic elements is studied. More than 13 million small-scale magnetic elements are selected, and the following results are unclosed. (1) The quiet regions dominated the Sun's magnetic flux for about 8 years in the 12.25 year duration of Cycle 23. They contributed (0.94 - 1.44) $\times 10^{23}$ Mx flux to the Sun from the solar minimum to maximum. The monthly average magnetic flux of the quiet regions is 1.12 times that of active regions in the cycle. (2) The ratio of quiet region flux to that of the total Sun equally characterizes the course of a solar cycle. The 6-month running-average flux ratio of quiet region had been larger than 90.0% for 28 continuous months from July 2007 to October 2009, which characterizes very well the grand solar minima of Cycles 23-24. (3) From the small to large end of the flux spectrum, the variations of numbers and total flux of the network elements show no-correlation, anti-correlation, and correlation with sunspots, respectively. The anti-correlated elements, covering the flux of (2.9 - 32.0)$\times 10^{18}$ Mx, occupies 77.2% of total element number and 37.4% of quiet Sun flux. These results provide insight into reason for anti-correlated variations of small-scale magnetic activity during the solar cycle.

description: We consider a ferromagnetic spin-1 Bose-Einstein condensate (BEC) dispersively coupled to a unidirectional ring cavity. We show that the ability of a cavity to modify, in a highly nonlinear fashion, matter-wave phase shifts adds a new dimension to the study of spinor condensates both within and beyond the single-mode approximation. In addition to demonstrating strong matter-wave bistability as in our earlier publication [L. Zhou et al., Phys. Rev. Lett. 103, 160403 (2009)], we show that the interplay between atomic and cavity fields can greatly enrich both the physics of critical slowing down in spin mixing dynamics and the physics of spin-domain formation in spinor condensates.

In this webinar Dr Carolyn Hogg speaks about the work she has been doing with the Threatened Species Initiative to build genomic resources to understand and protect Australia’s threatened species. Using examples such as the Kroombit Tinker Frog and the Greater Bilby, Carolyn describes some of the complexities and challenges of generating genomes from short reads and HiFi reads for critically endangered species. She outlines the technologies and resources being used and how these are bridging the gap between genomicists, bioinformaticians and conservation experts to help save Australian species.

Touching From a Distance: Nursing and Carnal Hermeneutics
Creators: name: McCaffrey, Graham
Publisher: name: University of Calgary
Year: 2019
Subjects: hermeneutics, carnal hermeneutics: nursing; mental health

description: Carnal hermeneutics represents a new development in hermeneutic thinking, extending Merleau-Ponty’s work on embodiment. It is potentially useful for applied hermeneutics in nursing, which is a discipline of caring for and with bodies. In this paper, I take up key essays by Richard Kearney and Brian Treanor that establish themes in carnal hermeneutics, exploring them in relation to nursing. In the first part, I focus on medical nursing using an example from a student nurse’s practice to look at some of characteristics of nursing using a carnal hermeneutics lens. In the second part, the focus is on mental health nursing, considering how Treanor’s field of “new realism(s)” can help to give a fuller account of the physicality inherent in what has become conventionally separated off as “mental” health.

Is maternal emotion socialization associated with daughters’ eating disorder psychopathology and emotion regulation? A mediation study based on mothers’ reports
Creators: name: Rozworska, Karolina Anna
Publisher: name: University of British Columbia

description: There is an ongoing need to improve the models of and treatments for eating disorders (EDs), given the limited recovery rates. Emotion regulation difficulties predict and maintain these disorders but interventions that teach emotion regulation skills to individuals with EDs have not improved the overall treatment efficacy. Research in developmental psychology suggests that parents influence (socialize) emotion regulation of their adolescent children and can be utilized in treatment as emotion coaches. This can be a promising avenue for future interventions for EDs, if research demonstrates that parental emotion socialization is linked to youth’s ED psychopathology through youth’s emotion regulation, as suggested by theory. This study examined if three channels of emotion socialization – practices (emotion coaching, emotion dismissing, and positive beliefs about daughters’ anger), mothers’ emotion regulation, and expressed emotion (critical comments, emotional overinvolvement) – were associated with daughters’ ED psychopathology through daughters’ emotion regulation. Individual differences that might be associated with emotion socialization were also examined. 135 mothers of daughters either with or without an ED diagnosis completed a battery of measures. Daughters’ ages ranged from 12 to 24 years. Results indicated that mothers’ emotion coaching, emotion regulation difficulties, and critical comments were indirectly related to daughters’ ED psychopathology through daughters’ emotion dysregulation. Emotional overinvolvement was only linked to ED psychopathology directly. Mothers’ psychological functioning or daughters’ diagnostic status (presence or absence of an ED diagnosis) were not significantly related to emotion coaching, emotion dismissing, or positive beliefs about anger. This study is a first step towards understanding how emotion socialization, especially emotion coaching, is linked to ED psychopathology and it can inform future research and clinical practice.

description: Context. Pre-stellar cores are the birthplaces of Sun-like stars and represent the initial conditions for the assembly of protoplanetary systems. Due to their short lifespans, they are rare. In recent efforts to increase the number of such sources identified in the Solar neighbourhood, we have selected a sample of 40 starless cores from the publicly available core catalogs of the Herschel Gould Belt survey. In this work, we focus on one of the sources that stands out for its high central density: Corona Australis 151. Aims. We use molecular lines that trace dense gas (n>=10^6 cm-3) to confirm the exceptionally high density of this object, to study its physical structure, and to understand its evolutionary stage. Methods. We detected the N2H+ 3-2 and 5-4 transitions, and the N2D+ 3-2, 4-3, and 6-5 lines with the APEX telescope. We use the Herschel continuum data to infer a spherically symmetric model of the core's density and temperature. This is used as input to perform non-local-thermodynamic-equilibrium radiative transfer to fit the observed five lines. Results. Our analysis confirms that this core is characterised by very high densities (a few x 10^7 cm-3 at the centre) and cold temperatures. We infer a high deuteration level of N2D+/N2H+=0.50, indicative of an advanced evolutionary stage. In the large bandwidth covered by the APEX data, we detect several other deuterated species, including CHD2OH, D2CO, and ND3. We also detect multiple sulphurated species that present broader lines with signs of high-velocity wings. Conclusions. The observation of high-velocity wings and the fact that the linewidths of N2H+ and N2D+ become larger with increasing frequency can be interpreted either as an indication of supersonic infall motions developing in the central parts of a very evolved pre-stellar core or as the signature of outflows from a very low luminosity object (VeLLO). *SHORTENED*

Localization properties of random-mass Dirac fermions from real-space renormalization group

description: Localization properties of random-mass Dirac fermions for a realization of mass disorder, commonly referred to as Cho-Fisher model, is studied on the D-class chiral network. We show that a simple RG description captures accurately three phases: thermal metal and two insulators with quantized Hall conductances, as well as transitions between them (including critical exponents). We find that, with no randomness in phases on the links, transmission via the RG block exhibits a sizable portion of perfect resonances. Delocalization occurs by proliferation of these resonances to larger scales. Evolution of the thermal conductance distribution towards metallic fixed point is synchronized with evolution of signs of transmission coefficients, so that delocalization is accompanied with sign percolation

description: This article is devoted to the presentation of lambda_rex, an explicit substitution calculus with de Bruijn indexes and a simple notation. By being isomorphic to lambda_ex - a recent formalism with variable names -, lambda_rex accomplishes simulation of beta-reduction (Sim), preservation of beta-strong normalization (PSN) and meta-confluence (MC), among other desirable properties. Our calculus is based on a novel presentation of lambda_dB, using a swap notion that was originally devised by de Bruijn. Besides lambda_rex, two other indexed calculi isomorphic to lambda_x and lambda_xgc are presented, demonstrating the potential of our technique when applied to the design of indexed versions of known named calculi.

description: Poincare invariant quantum field theories can be formulated on non-commutative planes if the statistics of fields is twisted. This is equivalent to state that the coproduct on the Poincare group is suitably twisted. In the present work we present a twisted Poincare invariant quantum field theory at finite temperature. For that we use the formalism of Thermofield Dynamics (TFD). This TFD formalism is extend to incorporate interacting fields. This is a non trivial step, since the separation in positive and negative frequency terms is no longer valid in TFD. In particular, we prove the validity of Wick's theorem for twisted scalar quantum field at finite temperature.

Consistent model of magnetism in ferropnictides

description: The discovery of superconductivity in LaFeAsO introduced the ferropnictides as a major new class of superconducting compounds with critical temperatures second only to cuprates. The presence of magnetic iron makes ferropnictides radically different from cuprates. Antiferromagnetism of the parent compounds strongly suggests that superconductivity and magnetism are closely related. However, the character of magnetic interactions and spin fluctuations in ferropnictides, in spite of vigorous efforts, has until now resisted understanding within any conventional model of magnetism. Here we show that the most puzzling features can be naturally reconciled within a rather simple effective spin model with biquadratic interactions, which is consistent with electronic structure calculations. By going beyond the Heisenberg model, this description explains numerous experimentally observed properties, including the peculiarities of the spin wave spectrum, thin domain walls, crossover from first to second order phase transition under doping in some compounds, and offers new insight in the occurrence of the nematic phase above the antiferromagnetic phase transition.
