description: An extended generalization of the dynamic random phase approximation (DRPA) for L-component polymer systems is presented. Unlike the original version of the DRPA, which relates the (LxL) matrices of the collective density-density time correlation fumctions and the corresponding susceptibilities of polymer concentrated systems to those of the tracer macromolecules and so-called broken links system (BLS), our generalized DRPA solves this problem for (5xL)x(5xL) matrices of the coupled susceptibilities and time correlation functions of the component number, kinetic energy and flux densities. The presented technique is used to study propagation of sound and dynamic form-factor in disentangled (Rouse) monodisperse homopolymer melt. The calculated sound velocity and absorption coefficient reveal substantial frequency dispersion. The relaxation time is found to be N times less than the Rouse time (N is the degree of polymerization), which evidences strong dynamic screening because of interchain interaction. We discuss also some peculiarities of the Brillouin scattering in polymer melts. Besides, a new convenient expression for the dynamic structural function of the Rouse chain in (q,p)-representation is found.

Bounding energy growth in friction-less stochastic oscillators

description: The paper presents analytical and numerical results on energetics of non-harmonic, undamped, single-well, stochastic oscillators driven by additive Gaussian white noises. Absence of damping and the action of noise are responsible for lack of stationary states in such systems. We explore properties of average kinetic, potential and total energies along with the generalized equipartition relations. It is demonstrated that in the friction-less dynamics nonequilibrium stationary states can be produced by stochastic resetting. For an appropriate resetting protocol average energies become bounded. If the resetting protocol is not characterized by finite variance of renewal time intervals stochastic resetting can only slow down the growth of average energies but does not bound them. Under special conditions regarding frequency of resets, ratios of average energies follow the generalized equipartition relations.

description: Academic institutions may go beyond observing lexicographic ordering of authors in attempting to determine relative contributions to joint research. The present article examines incentive issues arising when applicants for promotion are requested to underline the name of any principal author(s). This mechanism is not generally incentive compatible. Recognizing the generally sequential nature of contribution reporting, a scheme which induces global truthful revelation is developed Punishment is imposed on prior movers making claims of authorship seniority which are contradicted by subsequent movers. Where applications are simultaneous, contradicted claims of seniority lead to group punishment in that no author is promoted.

description: Given relatively weak industrial safety incentives in New Zealand's accident compensation legislation, an important development has been the Health and Safety in Employment Act 1992. In addition to penalties imposed in the event of accidents involving loss, the Act also imposes penalties where accidents or losses have not occurred. Ordinary negligence rules are ex post in that both an accident and loss must occur before liability accrues, whereas negligence-based ex ante liability rules hold agents liable for deficient care prior to such deficiency being manifested in an accident. This paper examines whether breaches of statutory duties which do not give rise to accidents have a useful incentive-enhancing role when used in conjunction with ex post negligence rules. It is argued that ex ante standards may useffilly complement ex post liability rules where the latter are insufficient to induce appropriate levels of precaution due to the presence of errors in courts' decision-making processes. More strict standards than socially optimal precaution levels may be necessary since inspection probabilities and penalties are relatively low, while fines should be several times larger than expected accident costs resulting from deficient levels of care. The distribution of penalties emerging from the relevant case law is examined, and some, but not much, merit is found in continuing adherence to capped fines which in themselves further strengthens the case for stringent ex ante safety standards.
title: SPARC, a matricellular protein that protects cancer from therapy
Creators: name: Santangelo, Alessandra
Publisher: name: The Open University
Year: 2014

description: The matricellular protein SPARC (secreted protein acidic and rich in cysteine) is a master regulator of tissue stroma; it is expressed during tissue remodeling and repair and its impaired regulation has a role in fibrotic responses, in determining the composition of the tumor-associated stroma and, less expected, in regulating the immune response. The complexity of studying SPARC in cancer stems from its concomitant or alternative expression in tumor and/or stroma cells depending on the tumor histotypes. Extracellular matrix (ECM) gene profile of human breast carcinomas correlates SPARC expression with prognosis and response to therapy. In particular, a subgroup of breast tumors can be identified based on ECM gene signature headed by SPARC that correlates with tumor grade, bad prognosis and poor response to therapy. Epithelial to mesenchymal transition (EMT) has been associated to drug resistance and SPARC has been implicated in EMT. Nevertheless the source of SPARC and its path toward EMT and the associated drug resistance have not been identified yet. I have used a well-defined model of transgenic mouse mammary carcinoma expressing the mutated rat oncogene c-erB2 (HER-2/neu), under the mouse mammary turn or virus promoter, backcrossed with Sparc-/- mice to establish mammary carcinoma cell lines devoid of SPARC expression, in which SPARC can be restored by retroviral gene transduction. With this isogenic cell lines I have been able to show that SPARC expression in tumor cells induces EMT only in vivo, indicating that EMT is a micro environmental and not a cell autonomous process. Moreover, SPARC expressing tumors became resistant to treatment with Doxil (Doxil, a pegylated form of Doxorubicin). Investigating the environmental players responsible of EMT in SPARC transduced tumors, I found that myeloid cells and particularly the so called myeloid derived suppressor cells (MDSC) have a role in EMT and drug resistance depending on SPARC. SPARC does not change the number or ratio between the Ly6Ghigh and the Ly6Glow fractions of CD11b MDSC rather it determines the immunosuppressive phenotype of recruited myeloid cells. The data show that SPARC-forced expression increased the activation of pro-turn oral (CCL2, CCL5) and immunosuppressive (ArgI, NOS2, Cox-2) genes in monocyte-MDSC (the Ly6Glow fraction). Furthermore, the role of myeloid cells recruited in Doxil resistance and EMT has been proven adding bisphosphonate to Doxil during treatment. , Bisphosphonates have been shown to inhibit induction and function of myeloid suppressor cells. Indeed, Bisphosphonates addition reverted EMT, the immunosuppressive phenotype of myeloid cells and rendered SPARC-producing tumors sensitive to Doxil administration.

description: Na3Bi has attracted significant interest in both bulk form as a three-dimensional topological Dirac semimetal and in ultra-thin form as a wide-bandgap two-dimensional topological insulator. Its extreme air sensitivity has limited experimental efforts on thin- and ultra-thin films grown via molecular beam epitaxy to ultra-high vacuum environments. Here we demonstrate air-stable Na3Bi thin films passivated with magnesium difluoride (MgF2) or silicon (Si) capping layers. Electrical measurements show that deposition of MgF2 or Si has minimal impact on the transport properties of Na3Bi whilst in ultra-high vacuum. Importantly, the MgF2-passivated Na3Bi films are air-stable and remain metallic for over 100 hours after exposure to air, as compared to near instantaneous degradation when they are unpassivated. Air stability enables transfer of films to a conventional high-magnetic field cryostat, enabling quantum transport measurements which verify that the Dirac semimetal character of Na3Bi films is retained after air exposure.

description: In this paper we explore the problem of antiparticles in DSR1 and $κ$-Minkowski space-time following three different approaches inspired by the Lorentz invariant case: a) the dispersion relation, b) the Dirac equation in space-time and c) the Dirac equation in momentum space. We find that it is possible to define a map $S_{dsr}$ which gives the antiparticle sector from the negative frequency solutions of the wave equation. In $κ$-Poincaré, the corresponding map $S_{kp}$ is the antipodal mapping, which is different from $S_{dsr}$. The difference is related to the composition law, which is crucial to define the multiparticle sector of the theory. This discussion permits to show that the energy of the antiparticle in DSR is the positive root of the dispersion relation, which is consistent with phenomenological approaches.

description: We investigate departures of the Onsager relations in the nonlinear regime of electronic transport through mesoscopic systems. We show that the nonlinear current--voltage characteristic is not an even function of the magnetic field due only to the magnetic-field dependence of the screening potential within the conductor. We illustrate this result for two types of conductors: A quantum Hall bar with an antidot and a chaotic cavity connected to quantum point contacts. For the chaotic cavity we obtain through random matrix theory an asymmetry in the fluctuations of the nonlinear conductance that vanishes rapidly with the size of the contacts.

description: The study of multi-planet systems can reveal important aspects that challenge our knowledge of planet formation and evolution via determination of planetary system architectures and internal structures. The CHEOPS satellite, launched in Dec 2019, has spent the past year taking high-precision transit photometry of such systems with a key science goal of the mission to further our understanding of this sub-field of exoplanet research. In this talk, I will present work done to discover and characterise a multi-planet system consisting of a pair of sub-Neptunes, including the development of a novel photometry detrending method. Using space-based CHEOPS and TESS data, and ground-based LCOGT, NGTS, and ASTEP transit photometry, combined with HARPS radial velocities we confirm the system, and interestingly, find that whilst both planets have similar radii (~2.6 and ~2.7 Earth radii) they appear to have different masses (~13.5 and ~2.5 Earth masses) leading to a substantial density disparity. This result also means that planet b is one of the densest, well-characterised sub-Neptunes, and will likely become a benchmark planet for this mass-radius space. From internal structure and atmospheric escape modelling we find that whilst planet b may have a small or non-existent atmosphere, planet c likely has an extended envelope. Key knowledge about this system was unveiled via precise follow-up observations with CHEOPS and ground-based facilities, that underlines the importance of the synergy between detection and accurate follow-up missions. The precise photometry of this system may shed light on the formation of dense, sub-Neptunes, with the apparent density difference a potential relic of the evolution of the system that may be resolved by long-term precise photometric monitoring with missions such as PLATO.

description: Optical frequency standards, lasers stabilized to atomic or molecular transitions, are widely used in length metrology and laser ranging, provide a backbone for optical communications and lie at the heart of next-generation optical atomic clocks. Here we demonstrate a compact, low-power optical frequency standard based on the Doppler-free, two-photon transition in rubidium-87 at 778 nm implemented on a micro-optics breadboard. The optical standard achieves a fractional frequency stability of 2.9x10$^{-12}$/$\sqrtτ$ for averaging times $τ$ less than 10$^{3}$ s, has a volume of $\approx$35 cm$^3$ and operates on $\approx$450 mW of electrical power. These results demonstrate a key step towards the development of compact optical clocks and the broad dissemination of SI-traceable wavelength references.

description: We explore empirical relations between three different populations of high-redshift galaxies and their hosting dark halos employing the halo model approach. Specifically we consider Lyman-break galaxies at z\sim4 and at z\sim5, and Lyman-Alpha emitters at z\simeq 4.86. We adopt a halo occupation function prescription to parameterize the properties of their hosting halos and the efficiency of halo-dependent star formation. We find that the two LBG samples are well described by the halo model with an appropriate HOF. We obtain constraints on properties of their hosting halos. A typical mass of hosting halos for LBGs is 5\times10^{11}h^{-1}M_\odot and the expected number of LBGs per halo is \sim0.5, therefore there is an approximate one-to-one correspondence between halos and LBGs. We also find a sign of the minimum mass of LBG hosting halos decreasing with time. We discuss implications of these findings on the star formation history of LBGs. On the other hand, for LAEs, our simple HOF prescription fails to reproduce simultaneously the observed angular correlation function and the number density. This might imply either that the distribution of LAEs within hosting halos differs from that of dark matter, or that the strong large-scale correlation is due to the existence of an unusual, large overdense region, and so the survey region is not a representative of the z\sim5 universe, the definite answer should wait for a much wider survey of LAEs at high redshifts.

description: Over the last years, UBC Campus Sustainability Office and UBC Food Services have participated in the UBC Food System Project, aiming to identify barriers and create opportunities to enhance the sustainability of the UBC food system. Brenda Sawada, the Manager of UBC SEEDS, believes that there is a necessity to promote local food consumption on the UBC campus, and approached the marketing department to design a marketing campaign to support the project. In order to better understand current UBC students’ attitude on locally-produced food, an exploratory interview was conducted in October 2004. 31 students, including graduate students, residence students, and non-residence students, completed this interview. This exploratory interview revealed the need to educate UBC students on the positive relationship between consuming locally-grown products and campus sustainability. UBC students are generally aware of the economic benefits of consuming local produce, yet they do not have an understanding of how buy local will benefit UBC in the ecological and social aspects. Thus an educational campaign will be needed to increase students’ awareness on the relationship between consuming local produce and sustainability. Implementing an educational campaign should change residence students’ consumption patterns so that they will include more BC produce in their diet. Some elements of the educational campaign will include modification of the UBC Food Services website, point of sales promotion, information table, and a paragraph writing competition. Residence students’ feedback and evaluation on the campaign will be gathered after a short period of time to measure its effectiveness. The result will also be used to determine if UBCFS should expand the educational campaign to other student sectors of the university.

description: Quality of the faculty is one of the most important components of higher education’s quality assurance. Turnover among faculty however could undermine the efficiency, productivity and in some occasions, threats the institution’s long term survival. Preliminary interviews with human resource personnel of selected private higher institutions revealed a high turnover rate of 18%. This qualitative phenomenological study explored the reason on why faculty resigns their job. In depth interviews were conducted with faculty members from 5 private universities in Malaysia, using purposive sampling. The NVivo 8 software was used to analyze the data thematically. Seven major themes emerged from the analysis including; employer image, availability of external job opportunities, social media bullying, unfair performance measurement, unfair compensation, work over load and job Insecurity. Although some emerging themes could be traced to previous literatures, an emerging theme of social media bullying warrants further scrutiny. The research results could help private universities to strategize how to minimize the high turnover rates while optimizing the levels of faculty retention. Furthermore this research provides some initial insight on the role of social media bullying in turnover literature.

In d=4, iterative properties of four and five point dual conformal integrals manifest themselves in the famous BDS ansatz conjecture. In hep-th 1611.02179 it was also conjectured that a similar structure of integrals may reappear in d=6. We show that one can systematically, order by order in the number of loops, construct combinations of d=6 integrals with 1/(p^2)^2 propagators with an iterative structure similar to the d=4 case. Such combinations as a whole also respect dual conformal invariance but individual integrals may not.

description: Quantum turbulence in superfluid He-4 in narrow channels often takes the form of moving localized vortex tangles. Such tangles, called turbulent plugs, also serve as building blocks of quantum turbulence in wider channels. We report on a numerical study of various aspects of the dynamics and structure of turbulent plugs in a wide range of governing parameters. The unrestricted growth of the tangle in a long channel provides a unique view on a natural tangle structure including superfluid motion at many scales. We argue that the edges of the plugs propagate as turbulent fronts, following the advection-diffusion-reaction dynamics. This analysis shows that the dynamics of the two edges of the tangle have distinctly different nature. We provide an analytic solution of the equation of motion for the fronts that define their shape, velocities and effective diffusivity, and analyze these parameters for various flow conditions.

description: We present a novel route to realizing topological superconductivity using magnetic flux applied to a full superconducting shell surrounding a semiconducting nanowire core. In the destructive Little-Parks regime, reentrant regions of superconductivity are associated with integer number of phase windings in the shell. Tunneling into the core reveals a hard induced gap near zero applied flux, corresponding to zero phase winding, and a gapped region with a discrete zero-energy state around one applied flux quantum, Φ_0 = h/2e, corresponding to 2π phase winding. Theoretical analysis indicates that in the presence of radial spin-orbit coupling in the semiconductor, the winding of the superconducting phase can induce a transition to a topological phase supporting Majorana zero modes. Realistic modeling shows a topological phase persisting over a wide range of parameters, and reproduces experimental tunneling conductance data. Further measurements of Coulomb blockade peak spacing around one flux quantum in full-shell nanowire islands shows exponentially decreasing deviation from 1e periodicity with device length, consistent with Majorana modes at the ends of the nanowire.

description: We review recent applications of the real-space renormalization group (RG) approach to the integer quantum Hall (QH) transition. The RG approach, applied to the Chalker-Coddington network model, reproduces the critical distribution of the power transmission coefficients, i.e., two-terminal conductances, P_c(G), with very high accuracy. The RG flow of P(G) at energies away from the transition yields a value of the critical exponent, nu_G=2.39 +/- 0.01, that agrees with most accurate large-size lattice simulations. Analyzing the evolution of the distribution of phases of the transmission coefficients upon a step of the RG transformation, we obtain information about the energy-level statistics (ELS). From the fixed point of the RG transformation we extract a critical ELS. Away from the transition the ELS crosses over towards a Poisson distribution. Studying the scaling behavior of the ELS around the QH transition, we extract the critical exponent nu_ELS=2.37 +/- 0.02.

description: Microinsurance offers policies to cover four types of risk; life, health, accidental and property and is a key element for the financial inclusion of the poor. This study examined the influence of insurance literacy and demographics on the likely hood of having a micro-insurance policy. The survey was conducted in the National Capital Region (NCR), India. Micro-insurance literacy was measured using a Quiz. The demographic variables included in the study were gender, age, education, marital status, income and the type of employment. Data analysis was performed using descriptive statistics and binary logistic regression analysis. Results show that insurance literacy score, income, employment and education increased the likely hood of owning an insurance policy. Furthermore, it was found that the average insurance literacy was only (36 .75 %). Microinsurance can provide risk coverage to the poor which are the most vulnerable section of the society but so far almost 90 percent of the Indian population is uninsured. This study is warranted by the need to create a model that identifies the sections of society which are unlikely to own microinsurance thus contributing to the low offtake of insurance. This study may be beneficial to the government in terms of regulations, the insurance providers in designing their products and Non-Governmental Organizations (NGOs) so that they can reach out to the unlikely groups.

description: Electro-stimulation or modulation of deep brain regions is commonly used in clinical procedures for the treatment of several nervous system disorders. In particular, transcranial direct current stimulation (tDCS) is widely used as an affordable clinical application that is applied through electrodes attached to the scalp. However, it is difficult to determine the amount and distribution of the electric field (EF) in the different brain regions due to anatomical complexity and high inter-subject variability. Personalized tDCS is an emerging clinical procedure that is used to tolerate electrode montage for accurate targeting. This procedure is guided by computational head models generated from anatomical images such as MRI. Distribution of the EF in segmented head models can be calculated through simulation studies. Therefore, fast, accurate, and feasible segmentation of different brain structures would lead to a better adjustment for customized tDCS studies. In this study, a single-encoder multi-decoders convolutional neural network is proposed for deep brain segmentation. The proposed architecture is trained to segment seven deep brain structures using T1-weighted MRI. Network generated models are compared with a reference model constructed using a semi-automatic method, and it presents a high matching especially in Thalamus (Dice Coefficient (DC) = 94.70%), Caudate (DC = 91.98%) and Putamen (DC = 90.31%) structures. Electric field distribution during tDCS in generated and reference models matched well each other, suggesting its potential usefulness in clinical practice.

title: Durability of bonded crack retarders for aerospace

description: The increase in demand for aircraft focuses the structural designers and manufacturers towards the reduction of manufacturing cost and structural weight while maintaining high safety, damage tolerance, and structural integrity. These weight savings can be achieved by using large integral structures. However, large integral structures show reduced performance with respect to damage tolerant design due to lack of physical barriers that can arrest a growing crack such as presently exist in structures joined with rivets and bolts. Fibre metal laminates such as Glass Laminated Aluminium Reinforced Epoxy (GLARE) have been proven effective as bonded crack retarders (BCR) in reducing the fatigue crack growth rate and improving the life of metallic aircraft structures. A major problem associated with bonded crack retarders is the development of thermal residual stresses which may have negative impact on the performance of the structure. Hence, the objectives of this research are to investigate the thermal residual stress developed during the strap bonding process and the fatigue durability of bonded crack retarders. Extensive research performed in this dissertation covers the detailed investigation of thermal residual stresses and the fatigue durability of GLARE bonded crack retarders when incorporated onto different structural coupons and on an aircraft mock-up panel. Thermal residual stresses developed during the strap bonding process are very low and the application of a bonded crack retarder improved the fatigue performance of the specimen. The experimental data on residual stress measurements and fatigue testing provides information for researchers and aircraft structural designers to improve the performance and life of critical aircraft structures and the possibilities of incorporating the bonded crack retarder concept in the initial design and fabrication stages.
Cosmic Ray Acceleration by Spiral Shocks in the Galactic Wind

description: Cosmic ray acceleration by shocks related with Slipping Interaction Regions (SIRs) in the Galactic Wind is considered. SIRs are similar to Solar Wind Corotating Interaction Regions. The spiral structure of our Galaxy results in a strong nonuniformity of the Galactic Wind flow and in SIR formation at distances of 50 to 100 kpc. SIRs are not corotating with the gas and magnetic field because the angular velocity of the spiral pattern differs from that of the Galactic rotation. It is shown that the collective reacceleration of the cosmic ray particles with charge $Ze$ in the resulting shock ensemble can explain the observable cosmic ray spectrum beyond the "knee" up to energies of the order of $10^{17}Z$ eV. For the reaccelerated particles the Galactic Wind termination shock acts as a reflecting boundary.

Magnetic fields in the Milky Way and other spiral galaxies

description: The average strength of the total magnetic field in the Milky Way, derived from radio synchrotron data under the energy equipartition assumption, is 6\muG locally and \simeq 10\muG at 3 kpc Galactic radius. Optical and synchrotron polarization data yield a strength of the local regular field of \simeq 4\muG (an upper limit if anisotropic fields are present), while pulsar rotation measures give \simeq 1.5\muG (a lower limit if small-scale fluctuations in regular field strength and in thermal electron density are anticorrelated). In spiral arms of external galaxies, the total [regular] field strength is up to \simeq 35\muG [\simeq 15\muG]. In nuclear starburst regions the total field reaches \simeq 50\muG. Little is known about the global field structure in the Milky Way. The local regular field may be part of a ``magnetic arm'' between the optical arms, a feature that is known from other spiral galaxies. Unlike external galaxies, rotation measure data indicate several global field reversals in the Milky Way, but some of these could be due to field distortions. The Galaxy is surrounded by a thick radio disk of similar extent as around many edge-on spiral galaxies. While the regular field of the local disk is of even symmetry with respect to the plane (quadrupole), the regular field in the inner Galaxy or in the halo may be of dipole type. The Galactic center region hosts highly regular fields of up to milligauss strength which are oriented perpendicular to the plane.

SuperGZK neutrinos

description: The sources and fluxes of superGZK neutrinos, $E>10^{20}$ eV, are discussed. The fluxes of {\em cosmogenic neutrinos}, i.e. those produced by ultra-high energy cosmic rays (UHECR) interacting with CMB photons, are calculated in the models, which give the good fit to the observed flux of UHECR. The best fit given in no-evolutionary model with maximum acceleration energy $E_{\rm max}=1\times 10^{21}$ eV results in very low flux of superGZK neutrinos an order of magnitude lower than the observed flux of UHECR. The predicted neutrino flux becomes larger and observable by next generation detectors at energies $10^{20} - 10^{21}$ eV in the evolutionary models with $E_{\rm max}=1\times 10^{23}$ eV. The largest cosmogenic neutrino flux is given in models with very flat generation spectrum, e.g. $\propto E^{-2}$. The neutrino energies are naturally high in the models of {\em superheavy dark matter and topological defects}. Their fluxes can also be higher than those of cosmogenic neutrinos. The largest fluxes are given by {\em mirror neutrinos}, oscillating into ordinary neutrinos. Their fluxes obey some theoretical upper limit which is very weak, and in practice these fluxes are most efficiently limited now by observations of radio emission from neutrino-induced showers.

description: This research examines the impact of green innovation on the sustainable performance of Thai food industry implementing green industry initiatives in compliance with the national Green Industry Project. The correlation analysis was conducted on green supply chain integration (GSCI) and corporate social responsibility (CSR) as key influencing variables, while the green innovation was a moderator. A total of 441 samples were received from the total population of 8,520 accredited Green Industry Mark enterprises (GIM) (2016). Structural equation modeling (SEM) was employed to test the empirical data derived from surveys, which were collected from entrepreneurs and chief executive officers involved in the Thai food industry. The model indicated the absolute fit indices, confirming the validity and reliability of the SEM analysis. The findings confirmed the positive relationship of the selected key factors and their effect on the sustainable performance.
Intrinsic orbital moment and prediction of a large orbital Hall effect in the 2D transition metal dichalcogenides

description: Carrying information using generation and detection of the orbital current, instead of the spin current, is an emerging field of research, where the orbital Hall effect (OHE) is an important ingredient. Here, we propose a new mechanism of the OHE that occurs in {\it non-}centrosymmetric materials. We show that the broken inversion symmetry in the 2D transition metal dichalcogenides (TMDCs) causes a robust orbital moment, which flow in different directions due to the opposite Berry curvatures under an applied electric field, leading to a large OHE. This is in complete contrast to the inversion-symmetric systems, where the orbital moment is induced only by the external electric field. We show that the valley-orbital locking as well as the OHE both appear even in the absence of the spin-orbit coupling. The non-zero spin-orbit coupling leads to the well-known valley-spin locking and the spin Hall effect, which we find to be weak, making the TMDCs particularly suitable for direct observation of the OHE, with potential application in {\it orbitronics}.
