description: We theoretically study the transmission of a weak probe field under the influence of a strong pump field in a coupled nanomechanical resonator-superconducting microwave cavity system. Using the standard input-output theory, we find that both pulse delay (slow light effect) and advancement (fast light effect) of the probe field can appear in this coupled system provided that we choose the suitable detuning of the pump field from cavity resonance. The magnitude of the delay (advancement) can be tuned continuously by adjusting the power of the pump field. This technique demonstrates great potential in applications including microwave phase shifter and delay line.

description: „Was ich in der deutschen Debatte nie verstehen werde, ist, warum am Ende so viel mehr Bereitschaft da ist, Apple, Google, Facebook oder auch Alibaba die eigenen persönlichen Daten jeden Tag zur Verfügung zu stellen, als dann, wenn der eigene Staat einen Rahmen dafür setzt, Daten zum Wohle des Einzelnen - anonymisiert oder pseudonymisiert - zur Forschung und zum Mehrwert für alle Patientinnen und Patienten zu nutzen. Dann gibt es so ein Grundmisstrauen. Solange das so ist und es ein Grundvertrauen in amerikanische Großkonzerne und ein Grundmisstrauen in den eigenen Staat gibt, werden wir in der Digitalisierung nicht vorankommen.“ Mit diesem Appell warnte der Bundesgesundheitsminister Jens Spahn am 3. Juli 2020 vor dem Setzen falscher Prioritäten beim Datenschutz, im Rahmen der von ihm forcierten Digitalisierung im Gesundheitswesen. Diese von ihm kritisierte Inkonsequenz betrifft in Teilen auch den Autor dieser Arbeit. So hat dieser bei seinem letzten Arztbesuch die ausgehändigte „Patienteninformation zum Datenschutz“ erstmals kritisch beäugt und sich Gedanken darüber gemacht, ob der Arzt den alten Praxiscomputer ausreichend vor unberechtigtem Zugriff auf seine Daten schützt. Weniger Bedenken hingegen hat er, während er im Wartezimmer am Smartphone durch die sozialen Netzwerke stöbert und hierbei seine persönlichen Daten in sozialen Netzwerken preisgibt, deren Firmensitze teilweise sogar im Ausland liegen. Dass nicht nur der Autor von der Datenverarbeitung im digitalen Zeitalter betroffen ist, zeigt die „ARD/ZDF-Onlinestudie 2020“, nach der mittlerweile über 90% der deutschen Bevölkerung online sind und ein Viertel der Gesamtbevölkerung regelmäßig soziale Netzwerke nutzt. Doch nicht nur beim Arztbesuch, sondern auch im alltäglichen Leben gewinnt das Thema Datenschutz im E-Health-Bereich eine immer bedeutender werdende Rolle. Im pandemiegeprägten Jahr 2020 wurde zur Einführung der Corona-Warn-App über die digitale Datenverarbeitung im Gesundheitswesen kontrovers diskutiert. Kritiker bemängelten die staatliche Kontrolle, während Befürworter die Effektivität der App zur Pandemiebekämpfung mittels Nachverfolgung sowie die hohen Datenschutzstandards hervorheben.

Evaluation of ginsenosides in transactivation and transrepression of human glucocorticoid receptor alpha
Creators: name: Hu, Catherine
Publisher: name: University of British Columbia
Year: 2017

description: Ginsenosides are pharmacologically active compounds in ginseng, a medicinal herb that is highly valued and widely consumed. They are reported to have diverse effects, including neuromodulation, anticancer, and immunomodulation. Glucocorticoid receptor (GR) is a nuclear receptor involved in transcriptional regulation of genes in numerous important physiological processes, such as stress-related homeostasis, gluconeogenesis, bone remodeling, and anti-inflammation. Previous research suggested ginsenosides as agonists of rodent GRα. Studies on human GRα (hGRα) mainly focused on a single ginsenoside and its effect on either hGRα-mediated transactivation or transrepression. However, only a few ginsenosides (compound K, Rh1, Rh2, Re, Rg1) were examined and it is not known whether ginsenosides activate hGRα in an analog-selective manner. In this study, seven protopanaxadiol (PPD)-type ginsenosides (Rb1, Rb2, Rc, Rd, compound K, Rh2, PPD) and five protopanaxatriol (PPT)-type ginsenosides (Re, Rf, Rg1, Rh1, PPT) were investigated to determine whether they act as functional ligands of hGRα for both its transactivation and transrepression activity. In vitro time resolved-fluorescence resonance energy transfer (TR-FRET) competitive ligand-binding assay revealed that ginsenosides can weakly bind to the ligand-binding domain of hGRα. Among the selected ginsenosides, monoglycosylated PPD-type ginsenosides compound K and Rh2 exhibited strongest binding to the receptor. Dual-luciferase reporter gene assays employing firefly luciferase reporter vectors carrying either glucocorticoid response element or NF-κB response element were conducted in human colon adenocarcinoma cells (LS180). None of the ginsenosides increased or attenuated hGRα-mediated transactivation or transrepression activity. Furthermore, hGRα target gene (hTAT and hCBG) expression was studied in human hepatocellular carcinoma cells (HepG2) and quantified by real-time PCR. The data indicated that ginsenoside Rh2 did not influence hGRα target gene expression. In summary, among all PPD-type ginsenosides (Rb1, Rb2, Rc, Rd, compound K, Rh2, PPD) and PPT-type ginsenosides (Re, Rf, Rg1, Rh1, PPT) tested, monoglycosylated PPD-type ginsenosides compound K and Rh2 exhibited stronger binding to hGRα-LBD, while others could only bind weakly. Nevertheless, none of the ginsenosides could modulate hGRα activity or affect target gene expression. Therefore, these ginsenosides are not functional ligands of hGRα in LS180 and HepG2 cells.
The conceptualization of prudence in sixteenth-century art and architecture of the Veneto : from mythos to logos
Creators: name: Coughlin, Michael Trevor
Publisher: name: University of British Columbia
Year: 2020

description: This thesis investigates the connection between prudence and visual culture in the sixteenth-century Veneto. More specifically, I examine the iconographic transformation of the figure of Minerva, and how, through an adaptation from her mythical origins to a more astronomical association, the nature of prudence identified with the goddess became incorporated in art and architectural theory during the period. This study draws on Plato’s conceptions of myth and the impact of the Platonic academies, as well as treatises of architecture, and navigation. The role of poetry in the Platonic academies in Vicenza is also considered in order to reconstruct how debates about prudence and myth during the period were converted into visual forms. To begin, Anselmo Canera’s fresco of Prudence in the Palazzo Thiene (1542) in Vicenza is analyzed for how the personification of the virtue acquires a cosmological significance. Next, Daniele Barbaro’s villa at Maser (1558) is examined to explore the articulation of prudence in architecture. Drawing on Barbaro’s definition of prudence as a temporal conversation – where the present is in communication with past and future, Chapter Two considers relations between time and space in his villa. Chapter Three investigates the Villa Rotonda (1570) and argues that Andrea Palladio’s developing interest in prudence can be aligned with the plan of the building, and the choices it offers for moving through its interior spaces. Focusing on the tricipitium, an emblem for prudence and Titian’s Allegory of Prudence, this dissertation concludes by considering how the emblem and painting elicited engagement with the complex meanings that accrued to the virtue. By evaluating how pictorial and architectural representations of prudence substituted for written interpretations of the virtue for sixteenth-century Venetian humanists, this dissertation considers how visual imagery was sometimes perceived to be a better vehicle than the written word when it came to philosophical debates.

description: Die mit dem Stichtag 25. Mai 2018 in Kraft getretene Datenschutz-Grundverordnung (DS-GVO) hat zu einem enormen Anstieg der Aufmerksamkeit auf diesem Gebiet, sowohl bei den betroffenen Personen als auch bei den datenverarbeitenden Unternehmen geführt. Gemäß einer Aussage des Landesbeauftragten für den Datenschutz und die Informationsfreiheit Baden-Württemberg, Stefan Brink, konnte die Quote der aktiven Umsetzung der datenschutzrechtlichen Vorschriften in den Betrieben von bisher einem Drittel auf zwei Drittel mit positivem Trend angehoben werden. Seitdem die DSGVO Gültigkeit erlangt hat, werden Umfragen zur praktischen Umsetzung der DS-GVO durchgeführt. Kaum ein Ergebnis einer dieser Umfragen besagt, dass die Umsetzung bei allen Betrieben nahezu abgeschlossen wäre. Der Digitalverband Bitkom hat eine repräsentative Befragung unter 500 Unternehmen in ganz Deutschland durchgeführt. Fast eineinhalb Jahre nach dem Geltungsbeginn der DS-GVO hatten zwar zwei Drittel der Befragten die DS-GVO größtenteils umgesetzt, bei lediglich 25 Prozent war die Umsetzung bereits zum Zeitpunkt der Umfrage vollständig abgeschlossen. Auch daran lässt sich erkennen, dass sich in den ersten zwei Jahren einige Herausforderungen in der betrieblichen Praxis ergeben haben. Zum einen kennen die betroffenen Personen ihre Rechte besser als zuvor und zum anderen haben hohe Bußgelder bei Nichteinhaltung der gesetzlichen Vorschriften eine abschreckende Wirkung. Bisher sind diese zwar meist von erheblichen Bußgeldern und einer Abmahnwelle verschont geblieben, dennoch ist ein konsequentes Vorgehen der Aufsichtsbehörden zu beobachten. An der Verdreifachung des Arbeitsvolumens und der Aufstockung der Datenschutzbereiche sowohl bei den Behörden als auch in den Unternehmen lässt sich die gestiegene Bedeutung dieses Bereichs deutlich erkennen. Die Verarbeitung von personenbezogenen Daten stellt für viele Unternehmen einen äußerst hohen wirtschaftlichen Wert dar. Sie spielen eine derart große Rolle, dass sie bereits als „Währung der Zukunft“ bezeichnet werden. Gerade in Zeiten von Big Data und vielen neuen technischen Möglichkeiten im Bereich der Verarbeitung personenbezogener Daten sollen durch die DS-GVO Verbraucherrechte und die Privatsphäre geschützt werden. Die rechtlichen Anforderungen stellen die Unternehmen vor komplexe Aufgaben. Dadurch entsteht eine neue Art der Zusammenarbeit zwischen den Unternehmen, ihren Kunden, Lieferanten und sämtlichen externen Geschäftspartnern.

Radical methods for the synthesis of fluoroalkanes and fluoromethyl aryl ethers and copper-catalyzed three-component carboetherification of alkenes
Creators: name: Chatalova Sazepin, Claire
Publisher: name: University of British Columbia
Year: 2016

description: Fluorinated molecules have become popular compounds among pharmaceuticals. The introduction of fluorine atoms on bioactive compounds has indeed the potential to improve their biophysical properties. Given the utility of fluorinated substituents on pharmaceuticals, fluorine chemistry has become an area of intensive research. Despite the progress made in selective fluorination, however, radical fluorination has been limited notably due to the paucity of atomic fluorine sources. In this thesis, the uncovering of new atomic fluorine sources and the development of new radical fluorination methods will be described. Chapter 1 presents the importance of fluorinated molecules and the currently available fluorinating agents. A discussion on radical fluorination is presented that includes the most recent advances in the field. In Chapter 2, the exploratory work on the ability of electrophilic N—F fluorinating agents to transfer fluorine to alkyl radicals is detailed. Peresters were chosen as radical precursors and reacted with traditionally electrophilic fluorine sources, NFSI and Selectfluor®. Under those conditions, various fluoroalkanes could be synthesized in good yields. A radical fluorination method subsequently developed using Selectfluor® is described in Chapter 3. The ability of phenoxyacetic acid derivatives to undergo fluorodecarboxylation under UV-light excitation using Selectfluor® was demonstrated. The methodology was successfully applied to the synthesis of mono- and difluoromethyl aryl ethers in 40 to 86% yields. Chapter 4 details the application of the photofluorodecarboxylation to the synthesis of trifluoromethyl aryl ethers. It was found that the wavelength required for the substrate’s excitation led to the decomposition of the desired products. A method using benzophenone as a photosentizer was developed allowing the use of another wavelength to promote the reaction, which proved to be substrate dependent. The use of a faster fluorine transfer agent, XeF2, allowed the synthesis of trifluoromethoxy arenes in good yields. A copper catalyzed difunctionalization of alkenes, developed in collaboration with Prof. Jieping Zhu, is presented in Chapter 5. This reaction allows the direct introduction of alkyl nitriles via C—H activation. A C—O bond and a C—C bond were created in a single step. A wide range of α substituted styrenes were difunctionalized in yields up to 82%.

Static strain aging in low carbon ferrite-pearlite steel : forward and reverse loading
Creators: name: Mojtaba, Mansouri Arani
Publisher: name: University of British Columbia
Year: 2015

description: The combination of static strain aging and plastic strain reversal is important to understand for both the forming of components and also analysis of in service performance, for example, in the case of fabrication of pipeline, motor shafts or structural components in buildings and ships. Static strain aging phenomenon has been experimentally studied for the cases of forward and reverse re-straining after aging on a low carbon steel (0.16 wt% C) with a ferrite-pearlite microstructure. Torsion tests on hollow tubular samples were used for the mechanical tests. The shear strain on the surface of the sample was measured with the digital image correlation. The influence of the amount of pre-strain, aging time and temperature, and the strain path reversals on the stress-strain response after aging has been measured experimentally. A maximum increase of 46 MPa was obtained in the yield stress of the samples re-strained after full aging in the same direction as the initial straining. This maximum increase in yield stress as well as the rate of increment in yield strength during aging was almost independent of the amount of pre-strain and the increase in the flow stress occurred without a significant variation in the work hardening behavior. Further, it was shown that a yield point phenomenon was absent if the direction of re-straining after aging was reversed and the increase in the flow stress level after aging was proportional to the amount of pre-strain and increased with extended aging time. In this case, the absence of a sharp yield point after prolonged aging time led to the speculation that the activation of dislocations sources, rather than unpinning of locked dislocations in re-straining after aging was the controlling mechanisms although proof of this requires further investigation. Although it is difficult to unambiguously identify all of the underlying physical mechanisms, nevertheless, a comprehensive set of experimental results has been measured which can be used by the design engineer when considering cases where static strain ageing and strain path reversals are relevant for a ferrite-pearlite steel with 0.16 wt% carbon.

description: POLAR is a novel compact Compton X-ray polarimeter designed to measure the linear polarization of the prompt emission of Gamma Ray Bursts (GRB) and other strong transient sources such as soft gamma repeaters and solar flares in the energy range 50-500 keV. A detailed measurement of the polarization from astrophysical sources will lead to a better understanding of the source geometry and emission mechanisms. POLAR is expected to observe every year several GRBs with a minimum detectable polarization smaller than 10%, thanks to its large modulation factor, effective area, and field of view. POLAR consists of 1600 low-Z plastic scintillator bars, divided in 25 independent modular units, each read out by one flat-panel multi-anode photomultiplier. The design of POLAR is reviewed, and results of tests of one modular unit of the engineering and qualification model (EQM) of POLAR with synchrotron radiation are presented. After construction and testing of the full EQM, we will start building the flight model in 2011, in view of the launch foreseen in 2013.

Does salbutamol improve sprinting performance following endurance cycling?
Creators: name: Sinden, Sean
Publisher: name: University of British Columbia
Year: 2015

description: Salbutamol, an inhaled asthma medication, may have a number of extra-pulmonary effects throughout the body that may result in an ergogenic benefit during exercise. Purpose: To investigate the ergogenic effects of high-dose inhaled salbutamol on sprint performance following a prolonged, individualized, steady-state exercise bout; secondarily, to identify the systemic effects of salbutamol during steady-state exercise that might explain such an ergogenic finding. Methods: Using a eucapnic voluntary hyperpnoea test, ten male and ten female cyclists were tested for exercise-induced bronchoconstriction (EIB). Using a crossover design, participants inhaled either placebo or 1600g of salbutamol and subsequently completed two 75-minute constant power cycling bouts immediately followed by a 30-second Wingate test. Primary outcomes were those collected during the Wingate test: peak and mean power. Lactate, perceived exertion, ventilatory, and gas exchange measurements were collected throughout the steady-state bout. A repeated-measures ANOVA was utilized to assess the effects of sex, EIB status, and salbutamol on performance outcomes. Results: Lung function was improved following salbutamol inhalation (M = 8.3%, SD = 1.0%) compared to placebo (M = 1.0%, SD = 5.6%). The differences in peak and mean power between the salbutamol and placebo conditions were not found to be statistically significant. During the 75-minute endurance bout, carbohydrate utilization, heart rate, and minute ventilation were increased while ventilatory efficiency was decreased. In general, the effects of salbutamol were more pronounced in women relative to men, while no impactful differences were found as a function of EIB status. Conclusion: Despite inducing a possible increase in carbohydrate metabolism, salbutamol inhalation did not cause a significant increase in peak or mean power during a 30-second Wingate test.

description: In our recent work on concentrated suspensions of uniformly porous colloidal spheres with excluded volume interactions, a variety of short-time dynamic properties were calculated, except for the rotational self-diffusion coefficient. This missing quantity is included in the present paper. Using a precise hydrodynamic force multipole simulation method, the rotational self-diffusion coefficient is evaluated for concentrated suspensions of permeable particles. Results are presented for particle volume fractions up to 45%, and for a wide range of permeability values. From the simulation results and earlier results for the first-order virial coefficient, we find that the rotational self-diffusion coefficient of permeable spheres can be scaled to the corresponding coefficient of impermeable particles of the same size. We also show that a similar scaling applies to the translational self-diffusion coefficient considered earlier. From the scaling relations, accurate analytic approximations for the rotational and translational self-diffusion coefficients in concentrated systems are obtained, useful to the experimental analysis of permeable-particle diffusion. The simulation results for rotational diffusion of permeable particles are used to show that a generalized Stokes-Einstein-Debye relation between rotational self-diffusion coefficient and high-frequency viscosity is not satisfied.

description: Hollow-core photonic-crystal waveguides filled with cold atoms can support giant optical nonlinearities through nondispersive propagation of light tightly confined in the transverse direction. Here we explore electromagnetically induced transparency is such structures, considering a pair of counter-propagating weak quantum fields in the medium of coherently driven atoms in the ladder configuration. Strong dipole--dipole interactions between optically excited, polarized Rydberg states of the atoms translate into a large dispersive interaction between the two fields. This can be used to attain a spatially-homogeneous conditional phase shift of pi for two single-photon pulses, realizing a deterministic photonic phase gate, or to implement a quantum nondemolition measurement of the photon number in the signal pulse by a coherent probe, thereby achieving a heralded source of single or few photon pulses.

Phylogenetics and introgression of Habronattus jumping spiders using transcriptomes (Araneae:Salticidae)
Creators: name: Leduc-Robert, Geneviève
Publisher: name: University of British Columbia
Year: 2015

description: Habronattus is a diverse genus of jumping spiders with complex courtship displays and colourful ornaments in males. A well-resolved species phylogeny would provide an important framework to study these traits, but has not yet been achieved because of conflicting signals from the few genes available. While such discordant gene trees could be the result of deep coalescence in the recently diverged group, there are many indications that hybridization may have occurred and could be the source of conflict. To infer Habronattus phylogenetic relationships and to investigate the cause of gene tree discordance, we assembled transcriptomes for 34 Habronattus species and 2 outgroups. We conducted a concatenated phylogenetic analysis using Maximum Likelihood for 2.41 Mb of nuclear data and for 12.33 kb of mitochondrial data. The concatenated nuclear phylogeny was resolved with high bootstrap support (95-100%) at most nodes with some uncertainty surrounding the relationships of H. icenoglei, H. cambridgei, and H. oregonensis, and Pellenes cf. levii. There are several nodes of the mitochondrial phylogeny that are incongruent to the nuclear phylogeny and indicate possible mitochondrial introgression: the internal relationships of the americanus and the coecatus group, the relationship between the altanus, decorus, banksi, and americanus group, and between H. clypeatus and the coecatus group. To determine the extent of incomplete lineage sorting (ILS) and introgression, we analyzed gene tree discordance for loci longer than 1 kb using Bayesian Concordance Analysis (BCA) for the americanus group (679 loci) and the viridipes/clypeatus/coecatus (VCC) group (517 loci) and found high levels of genetic discordance, especially in VCC group. Finally, we tested specifically for nuclear introgression in the concatenated nuclear matrix with Patterson’s D statistics and DFOIL. We found nuclear introgression resulting in substantial admixture between americanus group species, and between H. sp. (ROBRT) and the clypeatus group, and more minimal nuclear introgression between the clypeatus group and the coecatus group, and between the americanus group and several distant species. Our results indicate that hybridization may have been historically common between phylogenetically distant species of Habronattus, and that reproductive isolation is yet to be complete across the Habronattus phylogeny.

description: Solar-thermal desalination (STD) is a potentially low-cost, sustainable approach for providing high-quality fresh water in the absence of water and energy infrastructures. Despite recent efforts to advance STD by improving heat-absorbing materials and system designs, the best strategies for maximizing STD performance remain uncertain. To address this problem, we identify three major steps in distillation-based STD: (i) light-to-heat energy conversion, (ii) thermal vapor generation, and (iii) conversion of vapor to water via condensation. Using specific water productivity as a quantitative metric for energy efficiency, we show that efficient recovery of the latent heat of condensation is critical for STD performance enhancement, because solar vapor generation has already been pushed toward its performance limit. We also demonstrate that STD cannot compete with photovoltaic reverse osmosis desalination in energy efficiency. We conclude by emphasizing the importance of factors other than energy efficiency, including cost, ease of maintenance, and applicability to hypersaline waters.

description: This thesis examines two topics in labor economics and policy evaluation. Chapter 1 provides an introduction. Chapter 2 addresses the estimation of the effects of the minimum wage on labor market outcomes in developing countries. The main finding is that, even in the absence of policy variation, that is, when the same level of the minimum wage holds for all the workers in the data, it is still possible to recover the effects of this policy under particular assumptions of a dual economy model. Using this result, the effects of the minimum wage in Brazil from 2001 to 2009 are estimated. It is shown that the minimum wage has considerably increased average wages and reduced wage inequality. However, these effects are accompanied by higher unemployment and an increase in the size of the informal sector. Overall, the loss of tax revenues from the outflow of workers to the informal sector and unemployment more than offsets the increase in wages. Thus, this minimum wage policy contributes to a decrease in the labor tax revenues collected by the government. Chapter 3 also considers estimation of the effects of the minimum wage on labor market outcomes in developing countries. However, this chapter explores the use of less restrictive assumptions regarding the joint distribution of sectors and wages. To ease the estimation of the model parameters, a parametric approach (maximum likelihood) is used. The results validate the conclusions obtained in the previous chapter. Chapter 4 investigates the estimation of policy effects in partially randomized designs. It is shown that when randomization is implemented in a stratified way, the usual tests of balance of characteristics between treatment and control groups can suffer from size distortions, lack of power, or both. A solution to this problem is proposed, and its performance is compared with the baseline estimators in a simulation. It is shown that the proposed test possesses the desirable characteristics of correct nominal size and consistency. Finally, to illustrate the use of these techniques, a stratified, randomized job training program is analyzed.

description: The Ultra-Fast Flash Observatory (UFFO) is a new space-based experiment to observe Gamma-Ray Bursts (GRBs). GRBs are the most luminous electromagnetic events in the universe and occur randomly in any direction. Therefore the UFFO consists of two telescopes; UFFO Burst Alert & Trigger Telescope (UBAT) to detect GRBs using a wide field-of-view (FOV), and a Slewing Mirror Telescope (SMT) to observe UV/optical events rapidly within the narrow, targeted FOV. The SMT is a Ritchey-Chretien telescope that uses a motorized mirror system and an Intensified Charge-Coupled Device (ICCD). When the GRB is triggered by the UBAT, the SMT receives the position information and rapidly tilts the mirror to the target. The ICCD start to take the data within a second after GRB is triggered. Here we give the details about the SMT readout electronics that deliver the data.

description: We report the discovery of HAT-P-30b, a transiting exoplanet orbiting the V=10.419 dwarf star GSC 0208-00722. The planet has a period P=2.810595+/-0.000005 d, transit epoch Tc = 2455456.46561+/-0.00037 (BJD), and transit duration 0.0887+/-0.0015 d. The host star has a mass of 1.24+/-0.04 Msun, radius of 1.21+/-0.05 Rsun, effective temperature 6304+/-88 K, and metallicity [Fe/H] = +0.13+/-0.08. The planetary companion has a mass of 0.711+/-0.028 Mjup, and radius of 1.340+/-0.065 Rjup yielding a mean density of 0.37+/-0.05 g cm^-3. We also present radial velocity measurements that were obtained throughout a transit that exhibit the Rossiter-McLaughlin effect. By modeling this effect we measure an angle of λ= 73.5+/-9.0 deg between the sky projections of the planet's orbit normal and the star's spin axis. HAT-P-30b represents another example of a close-in planet on a highly tilted orbit, and conforms to the previously noted pattern that tilted orbits are more common around stars with Teff > 6250 K.

description: Background: Inadequate infrastructure, security threats from ongoing armed conflict, and conservative socio-cultural and gender norms that favour large families and patriarchal power structures contribute to poor sexual and reproductive health (SRH) outcomes in North and South Kivu provinces, Democratic Republic of the Congo (DRC). In order to expand contraceptive and post-abortion care (PAC) access in North and South Kivu, CARE, the International Rescue Committee and Save the Children provided technical support to the Ministry of Health and health facilities in these regions. Partners acknowledged that community leaders, given their power to influence local customs, could play a critical role as agents of change in addressing inequitable gender norms, stigma surrounding SRH service utilization, and topics traditionally considered taboo within Congolese society. As such, partners actively engaged with community leaders through a variety of activities such as community mapping exercises, values clarification and transformation (VCAT) activities, situational analyses, and education. Methods: This manuscript presents findings from 12 key informant interviews (KIIs) with male political and non-political community leaders conducted in six rural health zones of North and South Kivu, DRC. Transcripts were analysed thematically to explore community leaders’ perceptions of their role in addressing the issue of unintended pregnancy in their communities. Results: While community leaders in this study expressed overall positive impressions of contraception and strong support for ensuring access to PAC services following spontaneous and induced abortions, the vast majority held negative beliefs concerning women who had induced abortion. Contrasting with their professed opposition to induced abortion, leaders’ commitment to mediating interpersonal conflict arising between community members and women who had abortions was overwhelming. Conclusion: Results from this study suggest that when thoughtfully engaged by health interventions, community leaders can be empowered to become advocates for SRH. While study participants were strong supporters of contraception and PAC, they expressed negative perceptions of induced abortion. Given the hypothesized link between the presence of induced abortion stigma and care-avoidance behavior, further engagement and values clarification exercises with leaders must be integrated into community mobilization and engagement activities in order to increase PAC utilization.

description: Movement is a fundamental characteristic of life, yet some invertebrate taxa, such as barnacles, permanently affix to a substratum as adults. Adult barnacles became ‘sessile’ over 500 Ma; however, we confirm that the epizoic sea turtle barnacle, Chelonibia testudinaria, has evolved the capacity for self-directed locomotion as adults. We also assess how these movements were affected by water currents and the distance between conspecifics. Finally, we microscopically examined the barnacle cement. Chelonibia testudinaria moved distances up to 78.6 mm yr−1 on loggerhead and green sea turtle hosts. Movements on live hosts and on acrylic panels occasionally involved abrupt course alterations of up to 90°. Our findings showed that barnacles tended to move directly against water flow and independent of nearby conspecifics. This suggests that these movements are not passively driven by external forces and instead are behaviourally directed. In addition, it indicates that these movements function primarily to facilitate feeding, not reproduction. While the mechanism enabling movement remained elusive, we observed that trails of cement bore signs of multi-layered, episodic secretion. We speculate that proximal causes of movement involve one or a combination of rapid shell growth, cement secretion coordinated with basal membrane lifting, and directed contraction of basal perimeter muscles.

description: Using nonequilibrium dynamical mean-field theory, we compute the time evolution of the current in a Mott insulator after a strong electric field is turned on. We observe the formation of a quasistationary state in which the current is almost time-independent although the system is constantly excited. At moderately strong fields this state is stable for quite long times. The stationary current exhibits a threshold behavior as a function of the field, in which the threshold increases with the Coulomb interaction and vanishes as the metal-insulator transition is approached.
