The emission line near 1319 A in solar and stellar spectra
Creators: name: Jordan, C.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: An emission line near 1319 A is one of the strongest unidentified lines in the ultraviolet spectra of cool dwarf stars. In most line lists it is identified as a transition in N I, although its intensity would then be anomalous and the observed wavelength does not fit precisely that expected for N I. The line is also observed in cool giant stars. The measured wavelength of the line in stellar spectra is 1318.94 (+,- 0.01) A. Observations of giant stars provide further evidence that this line is not due to N I. It is proposed that this line is a decay from a previously unknown level in S I, which lies above the first ionization limit. This is identified with the 3d singlet D (odd parity) term. The previous tentative assignment of this term to the S I line at 1309.3 A then needs to be revised. The 1309.3 A line has been identified here for the first time in an astrophysical source. The singlet D (odd parity) level could, in principle, be populated by collisions from nearby autoionizing levels that have large number-densities, through population by di-electronic capture. Spin-orbit interaction with the autoionizing triplet D (odd parity) term might also lead to di-electronic capture into the singlet D (odd parity) level. A line at 1309.87 A observed in cool giant stars is identified as a transition in P II, pumped by the O I resonance lines.

description: Entropy serves as a central observable in equilibrium thermodynamics. However, many biological and ecological systems operate far from thermal equilibrium. Here we show that entropy production can characterize the behavior of such nonequilibrium systems. To this end we calculate the entropy production for a population model that displays nonequilibrium behavior resulting from cyclic competition. At a critical point the dynamics exhibits a transition from large, limit-cycle like oscillations to small, erratic oscillations. We show that the entropy production peaks very close to the critical point and tends to zero upon deviating from it. We further provide analytical methods for computing the entropy production which agree excellently with numerical simulations.

Some peculiarities of motion of neutral and charged test particles in the field of a spherically symmetric charged object in General Relativity

description: We propose the method of investigation of radial motions for charged and neutral test particles in the Reissner-Nordström field by means of mass potential. In this context we analyze special features of interaction of charges and their motions in General Relativity and construct the radial motion classification. For test particles and a central source with charges $q$ and $Q$, respectively, the conditions of attraction (when $qQ>0$) and repulsion (when $qQ<0$) are obtained. The conditions of motionless test particle states with respect to the central source are investigated and, in addition, stability conditions for such static equilibrium states are found. It is shown that stable states are possible only for the bound states of weakly charged particles in the field of a naked singularity. Frequencies of small oscillations of test particles near their equilibrium positions are also found.

Polarization-sensitive absorption of THz radiation by interacting electrons in chirally stacked multilayer graphene
Creators: name: Trushin, Maxim
name: Schliemann, John
Publisher: name: Universität Regensburg
Year: 2012
Subjects: subject: 530 Physik

description: We show that opacity of a clean multilayer graphene flake depends on the helicity of the circular polarized electromagnetic radiation. The effect can be understood in terms of the pseudospin selection rules for the interband optical transitions in the presence of exchange electron-electron interactions which alter the pseudospin texture in momentum space. The interactions described within a semi-analytical Hartree--Fock approach lead to the formation of the topologically different broken--symmetry states characterized by Chern numbers and zero-field anomalous Hall conductivities.
Bioinformatic approaches for identifying single nucleotide variants and profiling alternative expression in cancer transcriptomes
Creators: name: Goya, Rodrigo
Publisher: name: University of British Columbia
Year: 2017

description: Over the last decade, the advent of high-throughput sequencing (HTS) has given us the ability to study DNA and RNA sequences at nucleotide resolution at an unprecedented speed and at a relatively low cost. This has been an invaluable tool in the study of cancer, allowing projects such as The Cancer Genome Atlas and the International Cancer Genome Consortium to sequence thousands of tumours from multiple cancer types. The ever-increasing amounts of data created by these projects demanded new analysis methods: in the first part of this thesis, I focus on method development for mutation calling in genome and transcriptome data. I present SNVMix, a single nucleotide variant (SNV) caller based on a set of probabilistic models created to adapt to variations in allele representation in a tumour. Differential allele representation in DNA can occur when multiple clones are present in the sequenced tumour, and in RNA can occur due to differences in gene expression or allele bias. These situations are nearly ubiquitously encountered in cancer sequencing studies, and thus need to be accounted for. I demonstrate that SNVMix was able to outperform another contemporary SNV caller that does not account for variations in allele representation. I also present BWA-R, an adaptation of the Burrows Wheeler Aligner, that can properly align RNA-Seq paired-end reads to a genome reference extended with exon-exon junction sequences formed through splicing. I show that BWA-R provides better alignments for SNV calling in transcriptomes, resulting in an increase in the proportion of true positive calls obtained. In the second part of this thesis, I analyze RNA-Seq data from a triple negative breast cancer (TNBC) cohort and describe the alternative splicing profiles of the previously defined Basal and NonBasal subgroups. TNBC is characterized by the absence of estrogen and progesterone receptors and human epidermal growth factor receptor 2 (HER2), which precludes the use of currently available targeted therapies. TNBC patients are thus treated with chemotherapy, and outcomes are generally poor. I identify alternatively expressed genes that may be relevant to the biology of these two subgroups and that could provide clues for further studies or treatment options.

description: We present a study of several systems in which a large scale field is generated over a turbulent background. These large scale fields usually break a symmetry of the forcing by selecting a direction. Under certain conditions, the large scale field displays reversals so that the symmetry of the forcing is recovered statistically. We present examples of such dynamics in the context of the dynamo instability, of two dimensional turbulent Kolmogorov flows and of turbulent Rayleigh-Bénard convection. In these systems reversals occur respectively for the dynamo magnetic field, for the large scale circulation generated by a periodic forcing in space and for the large scale roll generated by turbulent thermal convection. We compare the mechanisms involved and show that their properties depend on some symmetries of the system and on the way they are broken.

description: The chemical constituents of terrestrial and atmospheric waters originate from biomass burning, fertilizer runoff, and anthropogenic activity, among other sources, and their multi-phase chemistry is complex. Sunlight plays an essential role in aquatic chemistry. Photosensitizers in terrestrial and atmospheric waters absorb light to form highly reactive species such as triplet excited carbon (3C*), hydroxyl radical (•OH), and singlet oxygen (1O2), driving the photochemical transformations of dissolved organic matter (DOM) in the aqueous phase. Of note, these reactive species transform DOM compounds that do not undergo direct photolysis. DOM frequently undergoes a change in optical properties following photochemical processing, with implications for air quality, water quality, and human and animal health. The presence of inorganic minerals, such as the fertilizer compound struvite, in terrestrial or atmospheric waters introduces further complexity and impacts the photochemical processes that occur. Simplified proxy systems are created in the laboratory to simulate aquatic photochemical processes and evaluate the formation and/or photodegradation of photoproducts. These mixtures typically consist of a representative organic carbon (OC) compound and a photosensitizer, along with struvite or another inorganic mineral.

description: Using a 3+1 decomposition of spacetime, we derive a new formula to compute the gravitational light shifts as measured by two observers which are normal to the spacelike hypersurfaces defining the foliation. This formula is quite general and is also independent of the existence of Killing fields. Known examples are considered to illustrate the usefulness of the formula. In particular, we focus on the Sachs-Wolfe effect that arises in a perturbed Friedman-Robertson-Walker cosmology.

description: We report the observation of the circular ac Hall effect where the current is solely driven by the crossed ac electric and magnetic fields of circularly polarized radiation. Illuminating an unbiased monolayer sheet of graphene with circularly polarized terahertz radiation at room temperature generates—under oblique incidence—an electric current perpendicular to the plane of incidence, whose sign is reversed by switching the radiation helicity. Alike the classical dc Hall effect, the voltage is caused by crossed E and B fields which are, however rotating with the light’s frequency.

description: Background:Fibroblast growth factor 9 (FGF9) is reported to be associated with the pathogenesis of cancers. However, its clinic significance in prostate cancer (PCa) had not yet to be elucidated. The aim of this study was to investigate the diagnostic value of FGF9 in PCa. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) and western blot analyses were used to detect the expression of serum FGF9 at mRNA and protein level in 90 PCa patients, 48 prostatic benign diseases (PBD) patients and 30 normal individuals. The association between FGF9 and clinicopathological features was determined by Chi-square test. Receiver-operator characteristic (ROC) was established to evaluate the diagnostic performance of FGF9 and PSA. Results: Serum FGF9 expression was significantly elevated in PCa patients (p p FGF9 expression was also associated with lymph node metastasis (p = .010). The diagnostic value of FGF9 was higher than the conventional tumor marker PSA with a AUC of 0.846 combined with a sensitivity of 83.3% and a specificity of 81.1%. Conclusions: Serum FGF9 may be employed as a potential diagnostic biomarker of PCa.

description: Alkaline-earth like atoms with ultra-narrow optical transitions enable superradiance in steady state. The emitted light promises to have an unprecedented stability with a linewidth as narrow as a few millihertz. In order to evaluate the potential usefulness of this light source as an ultrastable oscillator in clock and precision metrology applications it is crucial to understand the noise properties of this device. In this paper we present a detailed analysis of the intensity fluctuations by means of Monte-Carlo simulations and semi-classical approximations. We find that the light exhibits bunching below threshold, is to a good approximation coherent in the superradiant regime, and is chaotic above the second threshold.

Genes optimized by evolution for accurate and fast translation encode in Archaea and Bacteria a broad and characteristic spectrum of protein functions

description: BACKGROUND: In many microbial genomes, a strong preference for a small number of codons can be observed in genes whose products are needed by the cell in large quantities. This codon usage bias (CUB) improves translational accuracy and speed and is one of several factors optimizing cell growth. Whereas CUB and the overrepresentation of individual proteins have been studied in detail, it is still unclear which high-level metabolic categories are subject to translational optimization in different habitats. RESULTS: In a systematic study of 388 microbial species, we have identified for each genome a specific subset of genes characterized by a marked CUB, which we named the effectome. As expected, gene products related to protein synthesis are abundant in both archaeal and bacterial effectomes. In addition, enzymes contributing to energy production and gene products involved in protein folding and stabilization are overrepresented. The comparison of genomes from eleven habitats shows that the environment has only a minor effect on the composition of the effectomes. As a paradigmatic example, we detailed the effectome content of 37 bacterial genomes that are most likely exposed to strongest selective pressure towards translational optimization. These effectomes accommodate a broad range of protein functions like enzymes related to glycolysis/gluconeogenesis and the TCA cycle, ATP synthases, aminoacyl-tRNA synthetases, chaperones, proteases that degrade misfolded proteins, protectants against oxidative damage, as well as cold shock and outer membrane proteins. CONCLUSIONS: We made clear that effectomes consist of specific subsets of the proteome being involved in several cellular functions. As expected, some functions are related to cell growth and affect speed and quality of protein synthesis. Additionally, the effectomes contain enzymes of central metabolic pathways and cellular functions sustaining microbial life under stress situations. These findings indicate that cell growth is an important but not the only factor modulating translational accuracy and speed by means of CUB.

The induced metastable state is vortex-like, and its persistence time grows exponentially with the noise strength. A variety of distinct scaling relations are observed depending on the relative strength of the sub-population noises.

description: The emergence of a novel pandemic human strain of influenza A (H1N1/09) virus in April 2009 has demonstrated the need for well-validated diagnostic tests that are broadly applicable, rapid, sensitive, and specific. The analytical performance and clinical validity of results generated with the novel Roche RealTime Ready Influenza A/H1N1 Detection Set using the LightCycler 2.0 instrument were characterized. Analytical performance was assessed by processing respiratory samples spiked with H1N1/09 and seasonal influenza A virus, a set of seasonal influenza A virus subtypes, and samples containing common viral and bacterial respiratory pathogens. The clinical validity of results was assessed in comparison to other assays by analyzing 359 specimens at three clinical sites and one reference laboratory. Direct sequencing was used to resolve samples with discrepant results. The assay detected virus concentrations down to <50 RNA copies per reverse transcription (RT)-quantitative PCR (qPCR). Various influenza A virus subtypes were covered. The analytical specificity was 100%. High clinical validity was demonstrated by the 99% positive agreement between seasonal influenza A viruses, 98% positive agreement between H1N1/09 viruses, and 88% agreement between negative results. The analytical sensitivity was compared to those of three other RT-qPCR assays and was found to be equivalent. The novel Roche RealTime Ready Influenza A/H1N1 Detection Set can be utilized on the widely used LightCycler platform. We demonstrate its usefulness for the rapid detection and surveillance of pandemic H1N1/09 influenza A virus infections.

description: We study first passage statistics of the Polya urn model. In this random process, the urn contains two types of balls. In each step, one ball is drawn randomly from the urn, and subsequently placed back into the urn together with an additional ball of the same type. We derive the probability G_n that the two types of balls are equal in number, for the first time, when there is a total of 2n balls. This first passage probability decays algebraically, G_n ~ n^{-2}, when n is large. We also derive the probability that a tie ever happens. This probability is between zero and one, so that a tie may occur in some realizations but not in others. The likelihood of a tie is appreciable only if the initial difference in the number balls is of the order of the square-root of the total number of balls.

It is shown that the spin-wave frequency is directly related to both the in-plane and perpendicular spin-transfer torques. In the low field regime the perpendicular torque can induce changes in the slope of the oscillation frequency versus applied voltage (df/dv) from negative (redshift) to positive (blueshift) values.

description: We report the analysis of high-resolution, high-S/N spectra of an extremely metal-poor, extremely C-rich red giant, Seg 1-7, in the Segue 1 system - described in the literature alternatively as an unusually extended globular cluster or an ultra-faint dwarf galaxy. The radial velocity of Seg 1-7 coincides precisely with the systemic velocity of Segue 1, and its chemical abundance signature of [Fe/H] = -3.52, [C/Fe] = +2.3, [N/Fe] = +0.8, [Na/Fe] = +0.53, [Mg/Fe] = +0.94, [Al/Fe] = +0.23 and [Ba/Fe] < -1.0 is similar to that of the rare and enigmatic class of Galactic halo objects designated CEMP-no (Carbon-rich, Extremely Metal-Poor and with no enhancement (over solar ratios) of heavy neutron-capture elements). This is the first star in a Milky Way ``satellite'' that unambiguously lies on the metal-poor, C-rich branch of the Aoki et al. (2007) bimodal distribution defined by field halo stars in the ([C/Fe], [Fe/H])-plane. Available data permit us only to identify Seg 1-7 as a member of an ultra-faint dwarf galaxy or as debris from the Sgr dwarf spheroidal galaxy. In either case, this demonstrates that at extremely low abundance, [Fe/H ] < -3.0, star formation and associated chemical evolution proceeded similarly in the progenitors of both the field halo and satellite systems. By extension, this is consistent with other recent suggestions the most metal-poor dwarf spheroidal and ultra-faint dwarf satellites were the building blocks of the Milky Way's outer halo.

Contributions of nucleus accumbens circuitry to aspects of aversively-motivated behaviors
Creators: name: Piantadosi, Patrick T.
Publisher: name: University of British Columbia
Year: 2017

description: The nucleus accumbens is a heterogeneous brain structure involved in the integration of limbic and cortical input and the coordination of motor output during behavior. Made up primarily of two major subregions, the nucleus accumbens core (NAcC) and shell (NAcS), this region has been suggested to contribute to dissociable aspects of appetitive behavior on the basis of differential functions localized within these subregions. Briefly, the NAcC may promote states of behavioral action during reward-seeking, while the NAcS may refine such behavior by actively inhibiting inappropriate or irrelevant actions. In Chapter 1, we discuss relevant research related to the dissociability of the NAcC and NAcS at the circuit and behavioral levels. In Chapters 2, 3, and 4, we examine the contribution of these two NAc subregions, as well as associated cortical and limbic structures, to Pavlovian and instrumental suppression. Results suggested that the NAcC acted to promote behavioral indices of reward-seeking vigor, while the NAcS was necessary for the appropriate instantiation and expression of conditioned suppression. In Chapter 5, we probed the relevance of these NAc subregions to the performance of a novel active/passive avoidance behavior. On this task, rats had to dynamically promote or inhibit their responding, guided by discrete cues, to avoid a painful stimulus. While both NAc subregions were necessary for promoting behavior during active avoidance trials, only the NAcS was required for inhibiting responding during presentations of the passive avoidance stimulus. A control study suggested that neither NAc subregion was necessary for unconditioned responding to foot-shock, indicating that the previous results could not be explained by changes in pain sensitivity. We also probed the role of monoaminergic transmission to motivational conflict and active/passive avoidance by systemically administering d-amphetamine (AMPH) to a subset of animals in Chapter 3 and 4. These results suggested that AMPH promoted punishment induced inhibition of behavior during motivational conflict, but had the opposite effect during passive avoidance trials, inducing pressing despite punishment. Chapter 5 discusses these results in the framework of a dichotomy between response-promotion and response-inhibition, relating these findings to extant literature in the appetitive and aversive domains.

description: We describe a new way to access the chiral odd transversity parton distribution in the proton through the photoproduction of lepton pairs on transversely polarized target. The basic ingredient is the interference of the Bethe Heitler or Drell-Yan amplitudes with the amplitude of a process, where the photon couples to quarks through its twist-2 chiral-odd distribution amplitude. This approach permits to scan experimentally the shape of the transversity distribution in a nucleon as well as the photon distribution amplitude.

description: In CsBr:OH- both librational transitions and the “non Devonshire” line have been found. CsBr:OD- displays the expected isotope shift of a librator. Narrow lines in CsBr and CsI, observed directly above the two phonon lattice absorption, are tentatively explained as due to OH- aggregates.

Subjects: subject: 530 Physik

description: Measurements of the far infrared absorption due to In+ and Tl+ impurities in CsBr and CsI single crystals yielded low frequency resonances with narrow linewidths at 11.0 cm−1 in CsBr:In+, 12.0 cm−1 in CsI:In+, 14.1 cm−1 in CsI:Tl+, and 16.95 cm−1 in CsBr:Tl+. The frequencies of the resonant band modes in the Tl+ doped crystals shift to higher values with increasing temperature. Using a model of the perturbed crystal which involves the mass defect and the change of the central force constants between the defect and its eight nearest neighbours, the force constant change is fitted to the various resonance frequencies. The resulting linewidths are compared with the experimentally determined values.

description: The infrared spectra of amorphous films of GaP, GaAs, GaSb, InAs, and Ge prepared by sputtering have been measured from 10 to 4000 cm−1. The absorption spectra in the region of the “optical” phonon frequencies show similarities to the phonon density of states as deduced from Raman scattering but the absorption becomes much smaller at low frequencies. It is shown that while the coupling constant for Raman scattering by an amorphous material varies as the square of the wave vector, it varies in the case of infrared absorption as its fourth power. The results are compared with those of Raman scattering and with the predictions of a simple model. Amorphe Filme aus Gap, GaAs, GaSb, InAs und Ge wurden durch Kathodenzerstäubung hergestellt und ihre Infrarotapektren von 10 bis 4000 cm−1 gemessen. Im Frequenzbereich der optischen Phononen zeigen die Absorptionsspektren Ähnlichkeiten mit der Zustandsdichte der Phononen, die aus der Ramanstreuung folgt, jedoch ist die Absorption bei niedrigen Frequenzen wesentlich geringer. Während die Kopplungskonstante der Ramanstreuung an einem amorphen Material sich wie das Quadrat des Wellenvektors verhält, wird gezeigt, daß sie im Falle der Infrarotabsorption proportional zu seiner vierten Potenz ist. Die Ergebnisse werden mit den Vorhersagen eines einfachen Modells verglichen.
Exploring the healthcare experiences of peritoneal dialysis patients with their nurses

description: Chronic kidney disease (CKD) is a multidimensional global health issue that can affect various individuals worldwide. Although renal transplantation is the preferred form of renal replacement therapy for most individuals with CKD, the lack of kidneys from suitable donors means that most of these individuals will not receive one. Many of these individuals living with CKD manage their kidney failure through peritoneal dialysis (PD) at home and under the guidance and support of nurses working with them in an outpatient clinic. Literature has suggested that healthcare providers perceive primary nursing as the ideal care delivery model for many patients and that the elements of primary nursing are correlated to improved patient outcomes. Although literature supports the use of primary nursing, there is very little known about this model from the perspectives of patients and the experiences of PD patients. The purpose of this study was to explore the nursing care experiences of PD patients managed by a primary nursing care delivery model and further understand the unique healthcare experiences of this population. Using interpretive description as a research methodology, 15 participants were purposefully sampled from an outpatient PD clinic and participated in one-on-one face-to-face interviews. Interviews were digitally audio-recorded and conducted using a semi-structured interview guide. Findings from the study illustrated that PD patients were not experiencing all of the elements associated with primary nursing. A modified form of primary nursing was being experienced by the patients in which they received individualized and comprehensive nursing care. The nursing care of the patients was underpinned by a philosophy of patient-centred care that emphasized relational engagement between patients and nurses. In addition, organizational influences of nursing care such as PD nurse availability and operational hours of the PD clinic contributed to the experiences of patients having to navigate through unforeseen challenges in their care. This study can inform future research involving the analysis of health outcomes for PD patients, understanding family perspectives, and exploring nursing leaders’ perceptions to further improve the nursing care experiences of PD patients.

Resource allocation in cooperative and heterogeneous wireless networks with energy harvesting

description: The number of wireless connected devices is increasing rapidly, owing to the increasing applications of Internet of Things (IoT) devices. To address the coverage and capacity demand in the future, the fifth generation (5G) network will have heterogeneous architecture with densely deployed small cells and relay nodes for cooperative communication. Since dense deployment of base stations and relay nodes incur high energy consumption, renewable energy harvesting is a promising technique of reducing non-renewable energy consumption. Meanwhile, with increasing demand of IoT applications, self-sustaining battery life is direly needed in low power sensor-like devices. Since installation of bulky renewable energy harvesting infrastructure is not feasible in such miniature sensor-like devices, wireless energy harvesting is another promising technique that enables self-sustaining battery life of such devices. In this thesis, we address the challenges of resource allocation in cooperative and heterogeneous wireless communication networks with renewable and wireless energy harvesting. First, we consider relay-based and user-based cooperation in uplink wireless-powered communication (WPC) to mitigate the ``doubly near-far" problem. We propose algorithms to jointly optimize resource allocation for downlink energy harvesting and uplink information transmission in uplink WPC network with relay-based and user-based cooperation. Our algorithms improve throughput performance of user equipments that are far from access point. Next, we address new challenges of interference management in heterogeneous networks (HetNets) when downlink simultaneous information and power transfer (SWIPT) is enabled in small cells. We jointly maximize energy harvesting rate and throughput of small cell users while keeping interference within tolerable level. In time-switching approach of SWIPT, we demonstrate significant improvement in the energy harvesting rate by enabling flexible interference tolerance in macrocell users. Finally, we address the conflict between maximization of throughput and minimization of power cost in HetNets with renewable energy harvesting. We propose different online and offline algorithms to determine dynamic base station activation policy jointly with downlink resource allocation to optimize the trade-off between throughput performance and the associated power cost. Our algorithms demonstrate significant increase in throughput and decrease in non-renewable power consumption when compared to the baseline schemes. Performances of the proposed algorithms are analyzed through numerical simulations.

description: The purely ferroelastic phase transition at 481 K of agr-Sb5O7I has been investigated by Raman scattering. In the ferroelastic phase a strongly damped soft mode was observed. The temperature variation of several lines, which disappear above Tc, shows that the phase transition is weakly discontinuous. The experimental results and the structural changes of the crystal may be explained by assuming a zone boundary soft mode in the paraelastic phase.
