description: We present our discovery of a new hybrid pulsating subdwarf B star, J08069+1527. The effective temperature and surface gravity of 28,500$\pm$400\,K and 5.37$\pm$0.04\,dex, respectively, place this object inside the instability strip and also among other pulsating hot subdwarfs of a hybrid nature, right next to another fascinating star: Balloon\,090100001. From this proximity, we anticipated this star could pulsate in both high and low frequency modes. Indeed, our analysis of photometric data confirmed our prediction. We detected two peaks in the high frequency region and two other peaks at low frequencies. In addition, the amplitude of the dominant mode is very high and comparable to the dominant peaks in other hybrid subdwarf B stars. Since this star is bright, we performed time-series low resolution spectroscopy. Despite a low signal-to-noise (S/N) ratio, we were able to detect the main peak from these data. All our results strongly indicate that J08069+1527 is a high amplitude pulsating hot subdwarf B star of hybrid nature. By analogy to the other pulsating sdB star, we judge that the dominant mode we detected here has radial nature. Future stellar modeling should provide us with quite good constrains as p- and g-modes presented in this star are driven in different parts of its interior.

description: The quantistic zero-point motion of the carbon atoms is shown to induce strong effects on the opto-electronic properties of diamond and trans-polyacetylene, a conjugated polymer. By using an ab initio approach, we interpret the sub-gap states experimentally observed in diamond in terms of entangled electron-phonon states. These states also appear in trans-polyacetylene causing the formation of strong structures in the band-structure that even call into question the accuracy of the band theory. This imposes a critical revision of the results obtained for carbon-based nano-structures by assuming the atoms frozen in their equilibrium positions.

description: Using data from our Parkes & ATCA HI survey of six groups analogous to the Local Group, we find that the HI mass function and velocity distribution function for loose groups are the same as those for the Local Group. Both mass functions confirm that the "missing satellite" problem exists in other galaxy groups.

Ubiquitin carboxyl-terminal hydrolase l1 in alzheimer's disease
Creators: name: Zhang, Mingming
Publisher: name: University of British Columbia
Year: 2014

description: Alzheimer’s disease (AD) is the most common form of neurodegenerative diseases. Its neuropathology is characterized by extracellular amyloid plaque deposition, intracellular neuritic fibrillary tangles and neuronal loss. The extracellular amyloid plaque consists of amyloid β (Aβ) protein, which is derived from β- and γ- cleavage of amyloid precursor protein (APP). The abnormal accumulation of Aβ initiates neuronal dysfunction and plays an important role in AD pathogenesis. Ubiquitin carboxyl-terminal hydrolase L1 (UCHL1) is a de-ubiquitinating enzyme that cleaves ubiquitin at its carboxyl terminal. Dysfunction of UCHL1 has been implicated in various neurodegenerative diseases including childhood-onset progressive neurodegeneration, Alzheimer’s disease and Parkinson’s disease. UCHL1 protein level is reduced in AD and is inversely proportional to the number of neurofibrillary tangles in AD brains.Overexpression of UCHL1 could rescue learning and memory deficits in AD mouse model. However, whether UCHL1 affects APP processing, Aβ production or AD pathogenesis remains unknown. This thesis entails a thorough examination of the role of UCHL1 in AD pathogenesis. First, UCHL1 gene transcriptional regulation was investigated. We identified a functional NF-κB binding site within its 5’promoter region. We found that NF-κB signaling down-regulated UCHL1 transcription. Next we demonstrated that UCHL1 affected APP processing and Aβ production by facilitating the degradation of APP, the precursor of Aβ, and BACE1, the β-secretase in vivo. The results were verified by transgene expression and pharmacological inhibition of UCHL1 in multiple cell lines. Moreover, we showed in neuroblastoma cell lines and primary neuronal culture that UCHL1 protected against oxidative stress- and Aβ-induced neuronal apoptosis by interfering with the caspase 8/caspase 3 pathway. Finally, we demonstrated that UCHL1 reduced Aβ production, inhibited amyloid plaque formation and rescued memory deficits in AD mouse models. In summary, this study investigated the effect of UCHL1 on AD pathogenesis. It demonstrated for the first time that UCHL1 delays the development of AD pathology by regulating APP processing and reducing Aβ production. Furthermore, our findings indicated that transgene expression of UCHL1 is a disease-modifying strategy for AD therapeutic design.

description: A recent detection of the peculiar neutron star X-ray binary Circinus X-1 with electronic very long baseline interferometry (e-VLBI) prompted the suggestion that compact, non-variable radio emission persists through the entire 16.6-day orbit of the binary system. We present the results of a high angular resolution monitoring campaign conducted with the Australian Long Baseline Array in real-time e-VLBI mode. e-VLBI observations of Circinus X-1 were made on alternate days over a period of 20 days covering the full binary orbit. A compact radio source associated with Circinus X-1 was clearly detected at orbital phases following periastron passage but no compact radio emission was detected at any other orbital phase, ruling out the presence of a persistent, compact emitting region at our sensitivity levels. The jet was not resolved at any epoch of our 1.4-GHz monitoring campaign, suggesting that the ultrarelativistic flow previously inferred to exist in this source is likely to be dark. We discuss these findings within the context of previous radio monitoring of Circinus X-1.

New Mechanism for Neutrino Mass Generation and Triply Charged Higgs Boson at the LHC

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In this talk, I present a new mechanism for the generation of neutrino masses via dimension 7 operators: llHH(H*H)/M^3. This leads to new formula for the light neutrino masses, m_ν~v^4/M^3. This is distinct from the usual see-saw formulae: m_ν~v^2/M. The scale of new physics can naturally be at the TeV scale. Microscopic theory that generated d=7 operator has an isospin 3/2 Higgs multiplet Φ, which contains a triply charged Higgs boson with mass around ~TeV or less. These particles can be produced at the LHC (and possibly at the Tevatron) with distinctive multi-W and multi-lepton final states. For some choice of the parameter space, these particles can also be long-lived with the possibility of displaced vertices, or even escaping the detector. Their leptonic decay modes carry information about the nature of the neutrino mass hierarchy.

description: The non-uniform magnetostatic field produced by the equilibrium and non equilibrium magnetic states of magnetic nanotubes has been investigated theoretically. We consider magnetic fields produced by actual equilibrium states and transverse and vortex domain walls confined within the nanostructure. Our calculations allow us to understand the importance of the magnetostatic field in nanomagnetism, which is frequently considered as a uniform field. Moreover, our results can be used as a basis for future research of others properties, such as the investigation of spin waves when domain walls are present, or the motion of a magnetic particle near a magnetic field.

description: The linked cell list algorithm is an essential part of molecular simulation software, both molecular dynamics and Monte Carlo. Though it scales linearly with the number of particles, there has been a constant interest in increasing its efficiency, because a large part of CPU time is spent to identify the interacting particles. Several recent publications proposed improvements to the algorithm and investigated their efficiency by applying them to particular setups. In this publication we develop a general method to evaluate the efficiency of these algorithms, which is mostly independent of the parameters of the simulation, and test it for a number of linked cell list algorithms. We also propose a combination of linked cell reordering and interaction sorting that shows a good efficiency for a broad range of simulation setups.

description: We simulate the light variability of the Ap star epsUMa using the observed surface distributions of Fe, Cr, Ca, Mn, Mg, Sr and Ti obtained with the help of Doppler Imaging technique. Using all photometric data available we specified light variations of epsUMa modulated by its rotation from far UV to IR. We employed the LLmodels stellar model atmosphere code to predict the light variability in different photometric systems. The rotational period of epsUMa is refined to 5d088631(18). It is shown that the observed light variability can be explained as a result of the redistribution of radiative flux from the UV spectral region to the visual caused by the inhomogeneous surface distribution of chemical elements. Among seven mapped elements, only Fe and Cr significantly contribute to the amplitude of the observed light variability. In general, we find a very good agreement between theory and observations. We confirm the important role of Fe and Cr to the magnitude of the well-known depression around 5200 Å through the analysis of the peculiar $a$-parameter. Finally, we show that the abundance spots of considered elements cannot explain the observed variability in near UV and $β$ index which are likely due to some other causes. The inhomogeneous surface distribution of chemical elements can explain most of the observed light variability of the A-type CP star epsUMa.

description: We present the latest combination of searches for a standard model (SM) Higgs boson in ppbar collisions at \sqrts= 1.96 TeV recorded by the CDF~II detector at the Fermilab Tevatron. Using data corresponding to 2.3-5.9 fb-1 of integrated luminosity, we perform searches in a number of different production and decay modes and then combine them to improve sensitivity. No excess in data above that expected from backgrounds is observed; therefore, we set upper limits on the production cross section times branching fraction as a function of the SM Higgs boson mass (mH). The combined observed (expected) limit is 1.9 (1.8) times the SM prediction at mH = 115 Gev/c^2 and 1.0 (1.1) times the SM prediction at mH = 165 GeV/c^2.

We show that the NMR spectra in this phase provide direct evidence for the emergence of the spatially distributed normal quasiparticle regions. The quantitative analysis for the field evolution of the paramagnetic magnetization and newly-emerged low-energy quasiparticle density of states is consistent with the nodal plane formation, which is characterized by an order parameter in the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state. The NMR spectra also suggest that the spatially uniform spin-density wave is induced in the FFLO phase.

description: The magnetostatic interaction between two ferromagnetic microwires is calculated as a function of their geometric parameters and compared with those measured through magnetic hysteresis loops of glass-coated amorphous Fe% $_{77.5}$Si$_{7.5}$B$_{15}$ microwires. The hysteresis loops are characterized by well-defined Barkhausen jumps corresponding each to the magnetization reversal of individual microwires, separated by horizontal plateaux. It is shown that the magnetostatic interaction between them is responsible for the appearance of these plateaux. Finally, using the expression for the magnetostatic interaction is trivial to obtain the interacting force between microwires. Our results are intended to provide guidelines for the use of these microwires with technological purpose such as the fabrication of magnetic sensors.

description: Based on the high sensitivity of Compton scattering off ultra relativistic electrons, the possibility of anisotropies in the speed of light is investigated. The result discussed in this contribution is based on the gamma-ray beam of the ESRF's GRAAL facility (Grenoble, France) and the search for sidereal variations in the energy of the Compton-edge photons. The absence of oscillations yields the two-sided limit of 1.6 x 10^{-14} at 95 % confidence level on a combination of photon and electron coefficients of the minimal Standard Model Extension (mSME). This new constraint provides an improvement over previous bounds by one order of magnitude.

description: In dieser Arbeit entwickele ich Verfahren, um während der Interaktion mit einem prozessbasierten System, einzelne Prozessschritte anhand des Nutzungsverhaltens zu bewerten und Störungen im Prozess zu erkennen. Darüber hinaus mache ich menschliche Verhaltensanalysen für weitere Entwicklungsprozesse von prozessbasierten Systemen verwendbar.
 Ich integriere dazu verschiedene Arten der Prozessstörung in einem mithilfe von nutzerorientierten Entwicklungskonzepten erstellten Montageassistenzsystem, um natürliche menschliche Reaktionen auf Störungen auszulösen und somit die von mir entwickelten Verfahren der Erkennung dieser Schwierigkeiten zu evaluieren. Ich zeige, dass eine multimodale menschliche Verhaltensanalyse in der Lage ist, zusätzlich zu den durch die Versuchspersonen erkannten und verbalisierten schwerwiegenden Störungen weitere Verbesserungspotentiale im Prozess aufzuzeigen. Bei der Analyse menschlichen Verhaltens betrachte ich neben der direkten System-Interaktion und der Dauer einzelner Prozessschritte vor allem die Analyse des Gesichtes und der Kopfbewegung. Ich entwickle sowohl überwachte als auch unüberwachte Erkennungsverfahren. Die Modellierung als ein binäres Entscheidungsproblem und die Evaluation dieses überwachten Verfahrens machen deutlich, dass eine Unterscheidung zwischen Prozessschritten mit schwerwiegenden Störungen und allen anderen Prozessschritten möglich ist. Die gelernten Modelle erzielen dabei zumeist nur befriedigende Leistungen. Bei der Verwendung von unüberwachten Methoden beschreibe ich ein neuartiges Verfahren, welches anhand eines gelernten Modells von \glqq{}normalem menschlichen Verhaltens\grqq{} während eines Prozessschrittes zuverlässig Prozessschritte mit abweichenden Verhaltensweisen identifizieren kann.
 Durch die Anwendung der entwickelten Verfahren in einer digitalen Lernumgebung und somit einen deutlich anderen Bereich der Mensch-System Interaktion zeige ich schließlich die Generalisierbarkeit meiner entwickelten Methoden. Dabei sind die überwachten Verfahren in der Lage, menschliche Fehler vorherzusagen und die unüberwachten Verfahren können einzelne Aufgabenabschnitte in Hinblick auf ihre Schwierigkeit vergleichen.

description: Dust extinction is generally the least tractable systematic uncertainty in astronomy, and particularly in supernova science. Often in the past, studies have used the equivalent width of Na I D absorption measured from low-resolution spectra as proxies for extinction, based on tentative correlations that were drawn from limited data sets. We show here, based on 443 low-resolution spectra of 172 Type Ia supernovae for which we have measured the dust extinction as well as the equivalent width of Na I D, that the two barely correlate. We briefly examine the causes for this large scatter that effectively prevents one from inferring extinction using this method.

description: Dark soliton formation in mode-locked lasers is investigated by means of a power-energy saturation model which incorporates gain and filtering saturated with energy, and loss saturated with power. It is found that general initial conditions evolve into dark solitons under appropriate requirements also met in the experimental observations. The resulting pulses are well approximated by dark solitons of the unperturbed nonlinear Schrödinger equation. Notably, the same framework also describes bright pulses in anomalous and normally dispersive lasers.

We show that the cross section essentially differs from the result obtained in the Born approximation as well as form the result which takes into account the Coulomb corrections under assumption that both electron and positron are ultrarelativistic. The cross section of bremsstrahlung in a strong Coulomb field by a high-energy electron is also obtained in the region where the final electron is not ultrarelativistic.

A Histological observation of inflammatory cells in the rabbit Achilles tendon due to overuse injury
Creators: name: Almohimeed, Bandar Suliman
Publisher: name: University of British Columbia
Year: 2014

description: The presence or absence of inflammatory cells in chronic Achilles tendinopathy has been a controversial subject in previous studies. Macrophages, T lymphocytes, and neutrophils have previously been detected in injured human Achilles tendons, whereas other authors have reported that there is no evidence for their occurrence. This controversy may stem from the fact that human Achilles tendon overuse injuries usually develop gradually over time, and the time course of inflammation in response to overuse has been difficult to establish in clinical populations. The aim of my study was to examine the presence of inflammatory cells in the Achilles tendon of rabbits that were subjected to repetitive mechanical loading of defined durations. Twenty-Four New Zealand male rabbits were subjected to repetitive mechanical loading of the Achilles tendon and grouped into four groups in this study, according to the exercise time period for each group: 0, 1, 3, and 6 weeks. Achilles tendons were harvested at the end of each time period. Achilles tendons sections were stained with Hematoxylin and Eosin to examine the histological changes. Both Neutrophils and T-lymphocytes were detected by Immunohistochemistry. Macrophages were detected using the Prussian blue staining. A very small number of inflammatory cells were detected in some tissue sections in the control group. Tissue sections from exercised groups 1, 3, and 6 weeks respectively, showed some qualitative changes in tendon morphology. Collagen bundles were disorganized, and hyalinized patches and spaces between collagen fibers were observed. Tenocyte nuclei were rounder and basophilic, and there was an increase in their numbers with loss of parallel alignment. Macrophages, T-lymphocytes, and neutrophils were detected in tendon sections, specifically in the paratenon. Statistically both lymphocytes and macrophages were significantly higher than control at 6 weeks. While the number of macrophages in the control was lower than the 6 weeks group, there was no significant difference between 1 week and 3 weeks. However, no lymphocytes were found at week 3. Neutrophils in all groups showed no significant difference. The evidence of inflammation was not evenly distributed, as some tissue sections from the same groups showed no evidence of inflammatory cells.

description: Wave-wave interaction in plasmas is a topic of important research since the 16th century. The formation of Langmuir solitons through the coupling of high-frequency (hf) Langmuir and low-frequency (lf) ion-acoustic waves, is one of the most interesting features in the context of turbulence in modern plasma physics. Moreover, quantum plasmas, which are ubiquitous in ultrasmall electronic devices, micromechanical systems as well as in dense astrophysical environments are a topic of current research. In the light of notable interests in such quantum plasmas, we present here a theoretical investigation on the nonlinear interaction of quantum Langmuir waves (QLWs) and quantum ion-acoustic waves (QIAWs), which are governed by the one-dimensional quantum Zakharov equations (QZEs). It is shown that a transition to spatiotemporal chaos (STC) occurs when the length scale of excitation of linear modes is larger than that of the most unstable ones. Such length scale is, however, to be larger (compared to the classical one) in presence of the quantum tunneling effect. The latter induces strong QIAW emission leading to the occurrence of collision and fusion among the patterns at an earlier time than the classical case. Moreover, numerical simulation of the QZEs reveals that many solitary patterns can be excited and saturated through the modulational instability (MI) of unstable harmonic modes. In a longer time, these solitons are seen to appear in the state of STC due to strong QIAW emission as well as by the collision and fusion in stochastic motion. The energy in the system is thus strongly redistributed, which may switch on the onset of Langmuir turbulence in quantum plasmas.

description: We present K-band spectroscopy of short period, "sub-gap" cataclysmic variable (CV) systems obtained using ISAAC on the VLT. We show the infrared spectra (IR) for nine systems below the 2-3 hour period gap: V2051 Oph, V436 Cen, EX Hya, VW Hyi, Z Cha, WX Hyi, V893 Sco, RZ Leo, and TY PsA. We are able to clearly detect the secondary star in all but WX Hyi, V893 Sco, and TY PsA. We present the first direct detection of the secondary stars of V2051 Oph, V436 Cen, and determine new spectral classifications for EX Hya, VW Hyi, Z Cha, and RZ Leo. We find that the CO band strengths of all but Z Cha appear normal for their spectral types, in contrast to their longer period cousins above the period gap. This brings the total number of CVs and pre-CVs with moderate resolution (R >~ 1500) IR spectroscopy to sixty-one systems: nineteen pre-CVs, thirty-one non-magnetic systems, and eleven magnetic or partially magnetic systems. We discuss the trends seen in the IR abundance patterns thus far, and highlight a potential link between anomalous abundances seen in the IR with the C IV/N V anomaly seen in the ultraviolet. We present a compilation of all systems with sufficient resolution IR observations to assess the CO band strengths, and, by proxy, obtain an estimate on the C abundance on the secondary star.

description: Software development is rarely an individual effort and generally involves teams of developers collaborating to generate good reliable code. Among the software code there exist technical dependencies that arise from software components using services from other components. The different ways of assigning the design, development, and testing of these software modules to people can cause various coordination problems among them. We claim that the collaboration of the developers, designers and testers must be related to and governed by the technical task structure. These collaboration practices are handled in what we call Socio-Technical Patterns. The TESNA project (Technical Social Network Analysis) we report on in this paper addresses this issue. We propose a method and a tool that a project manager can use in order to detect the socio-technical coordination problems. We test the method and tool in a case study of a small and innovative software product company.

Exploring the Impact of Socio-Technical Core-Periphery Structures in Open Source Software Development

description: In this paper we apply the social network concept of core-periphery structure to the sociotechnical structure of a software development team. We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

description: We use the charged tip of a low temperature scanning probe microscope to perturb the transport through a graphene nanoconstriction. Maps of the conductance as a function of tip position display concentric halos, and by following the expansion of the halos with back-gate voltage we are able to identify an elongated domain over the nanoconstriction where they originate. Amplitude modulations of the transmission resonances are correlated with the gradient of the tip-induced potential and we analyze this in terms of modified coupling between localized states.

description: We present the review of some new problems in cosmology and physics of stars in connection with future launching of WSO. We discuss three problems. UV observations of distant z > 6 quasars allow to obtain information on the soft < 1 KeV X-ray radiation of the accretion disk around a supermassive black hole because of its cosmological redshift. Really the region of X-ray radiation is insufficiently investigated because of high galactic absorption. In a result one will get important information on the reionization zone of the Universe. Astronomers from ESO revealed the effect of alignment of electric vectors of polarized QSOs. One of the probable mechanism of such alignment is the conversion of QSO radiation into low mass pseudoscalar particles (axions) in the extragalactic magnetic field. These boson like particles have been predicted by new SUSY particle physics theory. Since the probability of such conversion is increasing namely in UV spectral range one can expect the strong correlation between UV spectral energy distribution of QSO radiation and polarimetric data in the optical range. In the stellar physics one of the interesting problems is the origin of the X-ray sources with super Eddington luminosities. The results of UV observations of these X-ray sources will allow to find the origin of these sources as accreting intermediate mass black holes.

description: Agelenini C. L. Koch, 1837 Agelenini: Lehtinen 1967: 344; Bolzern, Burckhardt & Hänggi 2013: 822. Remarks: This tribe was mentioned in the two publications cited above, and the limits of the group were discussed in Lehtinen (1967) only. He included 11 genera in this tribe, four from the New World and the other seven restricted to Eurasia and Africa. Since Lehtinen’s (1967) revision, more genera have been described, and currently ten genera are assigned to this tribe in the Old World: Agelena Walckenaer, 1805, Agelenella Lehtinen, 1967, Ageleradix Xu & Li, 2007, Agelescape Levy, 1996, Allagelena Zhang, Zhu & Song, 2006, Benoitia Lehtinen, 1967, Huangyuania Song & Li, 1990, Kidugua Lehtinen, 1967, Mistaria Lehtinen, 1967, and Tikaderia Lehtinen, 1967. Three of these genera are monotypic and known by females only: Agelenella, Kidugua, and Tikaderia. Two genera, Ageleradix and Huangyuania, placed by Zhu, Wang & Zhang (2017) in Ageleninae, seem to be misplaced. They lack a patellar apophysis, and the conductor lacks a thumb-like base (Cb) in the middle part of the tegulum, two features that are present in all other members of this group. The placement of three monotypic genera known exclusively by females is also doubtful.
