description: Neutral hydrogen (HI) intensity mapping is a promising technique to probe the large-scale structure of the Universe, improving our understanding on the late-time accelerated expansion. In this work, we first scrutinize how an alternative cosmology, interacting dark energy (IDE), can affect the 21-cm angular power spectrum relative to the concordance $Λ$CDM model. We re-derive the 21-cm brightness temperature fluctuation in the context of such interaction and uncover an extra new contribution. Then we estimate the noise level of three upcoming HI intensity mapping surveys, BINGO, SKA1-MID Band$\,$1 and Band$\,$2, respectively, and employ a Fisher matrix approach to forecast their constraints on the IDE model. We find that while $\textit{Planck}\,$ 2018 maintains its dominion over early-Universe parameter constraints, BINGO and SKA1-MID Band$\,$2 put complementary bounding to the latest CMB measurements on dark energy equation of state $w$, the interacting strength $λ_i$ and the reduced Hubble constant $h$, and SKA1-MID Band$\,$1 even outperforms $\textit{Planck}\,$ 2018 in these late-Universe parameter constraints. The expected minimum uncertainties are given by SKA1-MID Band$\,$1+$\textit{Planck}\,$: $\sim 0.34\%$ on $w$, $\sim 0.22\%$ on $h$, $\sim 0.64\%$ on HI bias $b_{\rm HI}$, and an absolute uncertainty of about $3\times10^{-4}$ ($7\times10^{-4}$) on $λ_{1}$ ($λ_{2}$). Moreover, we quantify the effects from systematics of the redshift bin number, redshift-space distortions, foreground residuals and uncertainties on the measured HI fraction, $Ω_{\mathrm{HI}}(z)$. Our results indicate a bright prospect for HI intensity mapping surveys in constraining IDE, whether on their own or further by synergies with other measurements.

description: We systematically study the spectrum of open strings attached to half BPS giant gravitons in the N=4 SYM AdS/CFT setup. We find that some null trajectories along the giant graviton are actually null geodesics of AdS_5x S^5, so that we can study the problem in a plane wave limit setup. We also find the description of these states at weak 't Hooft coupling in the dual CFT. We show how the dual description is given by an open spin chain with variable number of sites. We analyze this system in detail and find numerical evidence for integrability. We also discover an interesting instability of long open strings in Ramond-Ramond backgrounds that is characterized by having a continuum spectrum of the string, which is separated from the ground state by a gap. This instability arises from accelerating the D-brane on which the strings end via the Ramond-Ramond field. From the integrable spin chain point of view, this instability prevents us from formulating the integrable structure in terms of a Bethe Ansatz construction.

description: High resolution angle resolved photoemission measurements and band structure calculations are carried out to study the electronic structure of BaMnSb$_2$. All the observed bands are nearly linear that extend to a wide energy range. The measured Fermi surface mainly consists of one hole pocket around $Γ$ and a strong spot at Y which are formed from the crossing points of the linear bands. The measured electronic structure of BaMnSb$_2$ is unusual and deviates strongly from the band structure calculations. These results will stimulate further efforts to theoretically understand the electronic structure of BaMnSb$_2$ and search for novel properties in this Dirac material.

description: We construct the Einstein field equations on a 4-dimensional brane embedded in an $m$-dimensional bulk where the matter fields are confined to the brane by means of a confining potential. As a result, an extra term in the Friedmann equation in a $m$-dimensional bulk appears that may be interpreted as the X-matter, providing a possible phenomenological explanation for the acceleration of the universe. The study of the relevant observational data suggests good agreement with the predictions of this model.

The bryophyte flora of Bridal Veil Falls, British Columbia : an analysis of its composition and diversity
Creators: name: Djan-Chekar, Nathalie
Publisher: name: University of British Columbia
Year: 2008

description: Bridal Veil Falls is a small provincial park located at the eastern extremity of the Fraser Lowland in southwestern British Columbia. This study presents an inventory of the bryophyte flora of Bridal Veil Falls Provincial Park and an adjacent boulder slope. This inventory provided the basis for a discussion of the ecology and geographical affinities of the bryoflora emphasizing the environmental and historical factors that are determinant of its composition. A key to the mosses is provided. Field work conducted between 1991 and 1992 and examination of herbarium specimens revealed a diverse bryoflora in comparison to areas of similar size in British Columbia's Lower Mainland. This bryoflora is composed of 210 species (150 mosses and 60 liverworts). In addition, Barbula convoluta var. gallinula was found new to British Columbia. An analysis of bryophyte occurrence in habitats showed that high species diversity can be attributed to the wide variety of both habitats available at the site and microenvironments associated with these different habitats. Variations of light, moisture, and edaphic conditions were found to be generally important sources of diversity. The bryoflora of Bridal Veil Falls has a strong circumboreal component. Its affinity with the rich bryoflora of coastal British Columbia is reflected by a large proportion of Pacific North American endemics and species of humid coastal regions. The availability of suitable microenvironments allows the occurrence of species of arctic-montane, mediterranean and strictly oceanic distribution. The bulk of the flora is probably derived from bryophyte populations that colonized the Lower Mainland of British Columbia from southern refugia after the retreat of the Wisconsin ice.

description: It has been suggested that Rapid Single Flux Quantum (RSFQ) devices could be used as the classical interface of superconducting qubit systems. One problem is that the interface acts as a dissipative environment for a qubit. Recently ways to modify the RSFQ damping to reduce the dissipation have been introduced. One of the solutions is to damp the Josephson junctions by a frequency-dependent linear circuit instead of the plain resistor. The approach has previously been experimentally tested with a simple SFQ comparator. In this paper we perform experiments with a full RSFQ circuit, and thus conclude that in terms of stable operation the approach is applicable for scalable RSFQ circuits. Realisation and optimisation issues are also discussed.

description: The properties of ideal tri-functional dendrimers with forty-five, ninety-three and one hundred and eighty-nine branches are investigated. Three methods are employed to calculate the mean-square radius of gyration, $g$-ratios, asphericity, shape parameters and form factor. These methods include a Kirchhoff matrix eigenvalue technique, the graph theory approach of Benhamou et al. (2004), and Monte Carlo simulations using a growth algorithm. A novel technique for counting paths in the graph representation of the dendrimers is presented. All the methods are in excellent agreement with each other and with available theoretical predictions. Dendrimers become more symmetrical as the generation and the number of branches increase.

description: A theoretical investigation associated with obliquely propagating ion-acoustic shock waves (IASHWs) in a three-component magnetized plasma having inertialess non-extensive electrons, inertial warm positive and negative ions has been performed. A Burgers equation is derived by employing the reductive perturbation method. Our plasma model supports both positive and negative shock structures under the consideration of non-extensive electrons. It is found that the positive and negative shock wave potentials increase with the oblique angle ($δ$) which arises due to the external magnetic field. It is also observed that the magnitude of the amplitude of positive and negative shock waves is not effected by the variation of the ion kinematic viscosity but the steepness of the positive and negative shock waves decreases with ion kinematic viscosity. The implications of our findings in space and laboratory plasmas are briefly discussed.

description: In the competing risks problem, an important role is played by the cumulative incidence function (CIF), whose value at time $t$ is the probability of failure by time $t$ from a particular type of failure in the presence of other risks. In some cases there are reasons to believe that the CIFs due to various types of failure are linearly ordered. El Barmi et al. [3] studied the estimation and inference procedures under this ordering when there are only two causes of failure. In this paper we extend the results to the case of $k$ CIFs, where $k\ge3$. Although the analyses are more challenging, we show that most of the results in the 2-sample case carry over to this $k$-sample case.

description: Teleoperation platforms often require the user to be situated at a fixed location to both visualize and control the movement of the robot and thus do not provide the operator with much mobility. One example is in existing robotic surgery solutions that require the surgeons to be away from the patient, attached to consoles where their heads must be fixed and their arms can only move in a limited space. This creates a barrier between physicians and patients that does not exist in normal surgery. To address this issue, we propose a mobile telesurgery solution where the surgeons are no longer mechanically limited to control consoles and are able to teleoperate the robots from the patient bedside, using their arms equipped with wireless sensors and viewing the endoscope video via optical see-through head-mounted displays (HMDs). We evaluate the feasibility and efficiency of our user interaction method compared to a standard surgical robotic manipulator via two tasks with different levels of required dexterity. The results indicate that with sufficient training our proposed platform can attain similar efficiency while providing added mobility for the operator.

description: Although partly present already in the case law of the Permanent Court of International Justice, the subject of the subsequent conduct (subsequent agreements and practice) of the parties to a treaty had not been been adequately addressed. Georg Nolte’s first report before the International Law Commission constitutes a turning point. Thereafter, its potential significance for the interpretation of an international treaty became apparent. The present thesis begins by providing the definition of the relevant terms in the framework of the Vienna Convention on the Law of Treaties. We proceed to link the subsequent conduct of the parties with the interpretative means and methods enumerated in article 31 of the said Convention. Next we explore the potential role of the subsequent conduct of the parties in the process of the modification of a treaty, given the close link between interpretation and modification. Taking into consideration international case law and observations of the theory of international law, we conclude by examining the complicated nexus between subsequent conduct and state consent. We especially examine the challenges posed by the former to the latter. International Law Commission’s draft conclusions with the commentary guide us through this process
Thermal regimes of HTS cylinders operating in devices for fault current limitation

description: We reveal obstacles related to the application of HTS cylinders in current limiting devices based on the superconducting - normal state transition. It is shown that, at the critical current density achieved presently in bulk materials, and especially in BSCCO-2212, the required thickness of the cylinder wall in a full-scale inductive device achieves several centimeters. A simple mathematical model of the operation of an inductive fault current limiter (FCL) is used to show that such cylinders cannot be cooled in admissible time after a fault clearing and, hence, the inductive FCLs and current-limiting transformers employing BSCCO cylinders do not return to the normal operation in the time required. For the recovery even with a non-current pause in the circuit, the cylinders are needed with the critical current density by an order higher than the existed ones.

The starting point is a microscopic Hamiltonian including a spin generalised BCS term and a Heisenberg exchange term. We find that coexistence of magnetisation and superconductivity depends on the sign of the energy-gradient of the DOS at Fermi level. We also compute the tunneling contribution to the Ginzburg-Landau free energy, and find expressions for the spin-currents and Josephson currents across a tunneling junction separating two ferromagnetic p-wave superconductors.

description: Automated technologies for quality inspection of fruits have attracted great interest in the food industry. The development of nondestructive mechanisms to assess the quality of individual fruit prior to sale may lead to an increase in overall product quality, value, and consequently, producer competitiveness. However, the existing methods have limitations. Herein, a texture sensor based on highly sensitive hair-like cilia receptors, to allow a quick quality evaluation of fruit is proposed. The texture sensor consists of up to 100 magnetized nanocomposite cilia attached to a chip with magnetoresistive sensors in a full Wheatstone bridge architecture. In this paper we demonstrate the use of ciliary sensors in scanning fruits (blueberries and strawberries) in different maturation stages. The contact of the cilia with the fruit skin provided qualitative information about its texture in terms of ripeness stage. Less mature fruits exhibited, on average, a highest peak voltage of 0.14 mV for blueberries and 0.12 mV for strawberries, while overripe fruits exhibited 0.58 mV and 0.56 mV, respectively. The results were confirmed by sensorial assessment of the fruit freshness, and therefore attesting the application potential of the sensing technology for fruit quality control.
Aerobic treatment of CTMP wastewater in sequencing batch reactors
Creators: name: Dubeski, Cara V.
Publisher: name: University of British Columbia
Year: 2008

description: This research evaluated the application of a bench-scale aerobic SBR system to the treatment of CTMP/TMP wastewater. The wastewater treated was from Quesnel River Pulp, and had a COD of approximately 7200 mg/I and BOD₅ of roughly 2700 mg/I. SBR cycle times used were 24 and 48 hours, with hydraulic retention times of 34.3 and 68.6 hours respectively. The 24-hour cycle consisted of 22 hours aeration, one hour settling and one hour decant. Sludge retention times were 20 days for most runs. By the end of the study, the sludge in the system had been run on effluent from the same source from the same mill for 1 and 1/2 years. For the runs without pH adjustment, COD removals of 32-41% and BOD₅ reductions of 70-75% were achieved by the end of each 24-hour cycle (after one hour in-situ settling). When the decanted wastewater was settled for an additional three hours, COD reductions of 53-59% and BOD₅ reductions of 90-94% were obtained. From intermediate time point samples, it was found that most of the oxygen demand reduction occurred within the first 16 hours of the cycle. Little improvement was found in effluent from 48-hour cycles compared to 24-hour cycles. The rate of COD removal was greatly decreased in the 48-hour cycles, even during the early hours of aeration. Comparison of columns with unregulated pH to pH-controlled columns at 6.5 and 7.5 pH showed little difference in COD removals. COD and BOD₅ percentage removals in samples after the longer settling, were almost as high as in other aerobic systems treating similar wastewaters, though the SBR system had a higher loading. MLVSS concentrations were 3900 to 4600 mg/I at the end of 24-hour cycles, and Sludge Volume Indices ranged from 54 to 78 ml/g (for reactors without pH adjustment). Sludge yields in the 24-hour cycle runs were about 0.12 kg MLVSS per kg COD removed, and 0.15-0.18 kg MLVSS per kg BOD₅ removed. This is only about one quarter the sludge yields typical in AS systems, both on a COD and BOD₅ basis. Some recommendations for the design of an SBR pilot system for a pulp mill are made.

description: We present the first mid-infrared (5.2-15.2 micron) spectra of Type Ia supernovae (SNe 2003hv and 2005df). The detection of Ni emission in SN 2005df 135 days after the explosion provides direct observational evidence of high-density nuclear burning forming a significant amount of stable Ni in a Type Ia supernova. The observed emission line profiles in the SN 2005df spectrum indicate a chemically stratified ejecta structure. The SN 2005df Ar lines also exhibit a two-pronged emission profile implying that the Ar emission deviates significantly from spherical symmetry. The spectrum of SN 2003hv also shows signs of asymmetry, exhibiting blueshifted [Co III] which matches the blueshift of [Fe II] lines in nearly coeval NIR spectra. Finally, local thermodynamic equilibrium abundance estimates for the yield of radioactive 56Ni give ~0.5 Msun, for SN 2003hv, but only ~0.13-0.22 Msun for the apparently subluminous SN 2005df, supporting the notion that the luminosity of SNe Ia is primarily a function of the radioactive 56Ni yield. The chemically stratified ejecta structure observed in SN 2005df matches the predictions of delayed-detonation (DD) models, but is entirely incompatible with current three-dimensional deflagration models. Furthermore the degree that this layering persists to the innermost regions of the supernova is difficult to explain even in a DD scenario, where the innermost ejecta are still the product of deflagration burning. Thus, while these results are roughly consistent with a delayed detonation, it is clear that a key piece of physics is still missing from our understanding of the earliest phases of SN Ia explosions.

description: For understanding the origin of anisotropies in the cosmic microwave background, rules to construct a quantized universe is proposed based on the dynamical triangulation method of the simplicial quantum gravity. A $d$-dimensional universe having the topology $ D^d $ is created numerically in terms of a simplicial manifold with $d$-simplices as the building blocks. The space coordinates of a universe are identified on the boundary surface $ S^{d-1} $, and the time coordinate is defined along the direction perpendicular to $ S^{d-1} $. Numerical simulations are made mainly for 2-dimensional universes, and analyzed to examine appropriateness of the construction rules by comparing to analytic results of the matrix model and the Liouville theory. Furthermore, a simulation in 4-dimension is made, and the result suggests an ability to analyze the observations on anisotropies by comparing to the scalar curvature correlation of a $ S^2 $-surface formed as the last scattering surface in the $ S^3 $ universe.

description: We define a bulk wormhole geometry interpolating between horizons of differing size and determine characteristics of the HRT surface in these geometries. This construction is dual to black hole mesostates, an intermediate coarse-graining of states between black hole microstates and the full black hole state. We analyze the distinguishability of these objects using the recently derived holographic Holevo information techniques, demonstrating novel phase transition behavior for such systems.

description: The observation of single-photon optomechanical effects is a desired task in cavity optomechanics. However, the realization of ultrastrong optomechanical interaction remains a big challenge. Here, we present an all-optical scheme to simulate ultrastrong optomechanical coupling based on a Fredkin-type interaction, which consists of two exchange-coupled modes with the coupling strength depending on the photon number in another controller mode. This coupling enhancement is assisted by the displacement amplification according to the physical idea of the Bogoliubov approximation, which is realized by utilizing a strong driving to pump one of the two exchanging modes. Our numerical simulations demonstrate that the enhanced optomechanical coupling can enter the single-photon strong-coupling and even ultrastrong-coupling regimes. We also show the creation of macroscopic quantum superposed states and the implementation of a weak-to-strong transition for quantum measurement in this system. This work will pave the way to quantum simulation of single-photon optomechanical effects with current experimental platforms.

description: This is a presentation made in the frame of a course on "Culture and Identity" at Stockholm University for students at the level of French III. The goal is to explore the consequences of the Dreyfus scandal (1894-1906) in France and abroad. The Dreyfus affair is not simply a historical scandal where the military staff was implicated, it is a topic for anthropological studies to understand the falsifications, the fake news and the attitudes of the different involved actors of this scandal. The rise of anti-Semitism with the increasingly important role of the press is also mentioned.

description: Η παρούσα διπλωματική εργασία αποσκοπεί στην ανάπτυξη ενός παιχνιδιού σοβαρού σκοπού για περιβάλλον εικονικής πραγματικότητας το οποίο θα έχει στόχο την μείωση των επιπέδων εργασιακού στρες. Για την υλοποίηση της ιδέας χρησιμοποιήθηκε η συσκευή εικονικής πραγματικότητας Oculus Go, ενώ για την ανάπτυξη της εφαρμογής και των βιβλιοθηκών που χρειάστηκαν για να υποστηρίξουν τη σύνδεση της με αισθητήρες αξιοποιήθηκαν η μηχανή παιγνίων Unity και το προγραμματιστικό περιβάλλον Android Studio αντίστοιχα. Για την εκτίμηση και αξιολόγηση των επιπέδων στρες χρησιμοποιήθηκαν δύο αισθητήρες, το Scosche Rhythm+ για την συλλογή σήματος καρδιακού ρυθμού και το Moodmetric Ring για τη συλλογή σήματος ηλεκτροδερμικής δραστηριότητας (EDA). Για την εκτίμηση της συσχέτισης των δύο σημάτων και την προσομοίωση συνθηκών στρες προκειμένου να ελεγχθεί η επίδραση του παιχνιδιού υλοποιήθηκε πειραματικό πρωτόκολλο με τη βοήθεια εθελοντών και ανάλυση των σημάτων στη προγραμματιστική γλώσσα R για την απεικόνιση της πραγματικής κατάστασης στρες του εκάστοτε χρήστη. Απώτερος στόχος του συστήματος είναι η έγκαιρη εκτίμηση των επιπέδων στρες στον εργασιακό χώρο και η παροχή ενός απλού και χρήσιμου εργαλείου για την άμεση αντιμετώπιση του.
description: The following diploma thesis aims to the development of a Virtual Reality serious game that will have the capacity to reduce the work stress levels. For the implementation of this idea was used the VR mask Oculus Go, while for the development of the application and the libraries needed for the application – sensor connection were used the game engine Unity and the programming environment Android Studio respectively. For the estimation and assessment of work stress levels were used two sensors, Scosche Rhythm+ for the collection of heart rate signal and Moodmetric Ring for the collection of EDA (electrodermal activity) signal. The estimation of the correlation between the two signals and the simulation of stress conditions in order to check the effect of the game were achieved with the implementation of experiments with the help of volunteers and the signal analysis in the programming language R for the depiction of the user’s real stress condition. Further aim of this project is the timely estimation of stress levels in workplace and the provision of a simple and useful tool for the immediate confrontation of stress.

description: Natural populations often show enhanced genetic drift consistent with a strong skew in their offspring number distribution. The skew arises because the variability of family sizes is either inherently strong or amplified by population expansions, leading to so-called `jackpot' events. The resulting allele frequency fluctuations are large and, therefore, challenge standard models of population genetics, which assume sufficiently narrow offspring distributions. While the neutral dynamics backward in time can be readily analyzed using coalescent approaches, we still know little about the effect of broad offspring distributions on the dynamics forward in time, especially with selection. Here, we employ an exact asymptotic analysis combined with a scaling hypothesis to demonstrate that over-dispersed frequency trajectories emerge from the competition of conventional forces, such as selection or mutations, with an emerging time-dependent sampling bias against the minor allele. The sampling bias arises from the characteristic time-dependence of the largest sampled family size within each allelic type. Using this insight, we establish simple scaling relations for allele frequency fluctuations, fixation probabilities, extinction times, and the site frequency spectra that arise when offspring numbers are distributed according to a power law $~n^{-(1+α)}$. To demonstrate that this coarse-grained model captures a wide variety of non-equilibrium dynamics, we validate our results in traveling waves, where the phenomenon of 'gene surfing' can produce any exponent $1

description: Η συνεχόμενη άνοδος της τεχνολογίας στο πέρασμα των χρόνων οδηγεί στην ανάγκη για ασφαλή τεχνολογικά συστήματα και ασφαλείς εφαρμογές. Κάθε μέρα γνωστοποιούνται νέες ευπάθειες και είδη επιθέσεων σε όλο τον κόσμο και η χρήση της ασφάλειας τόσο σε επίπεδο εφαρμογών όσο και σε επίπεδο συστημάτων αποτελεί αναπόσπαστο κομμάτι της σωστής και ακίνδυνης λειτουργίας τους. Ο αριθμός των ευπαθειών σε επίπεδο εφαρμογής έχει αυξηθεί και έχει προσπεράσει τον αντίστοιχο αριθμό σε συστήματα. Οι πολλαπλές τεχνικές που χρησιμοποιούνται για δημιουργία εφαρμογών και η «πανταχού παρούσα» προσβασιμότητα τους μπορούν να έχουν καταστροφικές συνέπειες τόσο στο χρήστη όσο και στον πάροχο. Με σκοπό την ενίσχυση της ασφάλειας τους, χρησιμοποιούνται πολλά προγράμματα και τεχνικές τις οποίες μπορούν να εκμεταλλευτούν οι χρήστες είτε για να αξιολογήσουν τις ευπάθειες του συστήματος τους είτε για να τις προσπελάσουν με απώτερο σκοπό την εκμετάλλευση τους. Η αξιολόγηση ευπαθειών και η προσπάθεια διείσδυσης σε μια εφαρμογή, είναι μια διαδικασία χρονοβόρα τις περισσότερες φορές αλλά απαραίτητη για την ομαλή και την ασφαλή λειτουργία της. Σκοπός της παρούσας διπλωματικής εργασίας είναι να γίνουν κατανοητοί οι όροι «αξιολόγηση ευπαθειών» και «προσπάθεια διείσδυσης» και να παρουσιαστούν τρόποι για την υλοποίηση τους. Επιπλέον, υλοποιούνται αξιολογήσεις ευπαθειών και προσπάθειες διείσδυσης με την χρήση συγκεκριμένων προγραμμάτων όπως Nikto και SQLMAP. Η χρήση των προγραμμάτων που προαναφέρθηκαν είναι ιδιαίτερα σημαντική καθώς μπορούν να αποτρέψουν αλλοίωση ή και απώλεια στοιχείων ακόμη και την ολική καταστροφή μιας εφαρμογής. Γίνεται ανάλυση των αποτελεσμάτων από την αναζήτηση ευπαθειών που έχει γίνει σε διάφορες εφαρμογές και εκτενή παρουσίαση της SQL Injection.
description: As years go by, the technology increase lead to the need of secure information systems and secure web applications. Every day new vulnerabilities are appeared and new attacks take place all over the world, so security is neened either on web applications neither to systems in order to take care of their services. Many techniques and ubiquitous access that used for web applications could cause disasters in the clients. Vulnerability Assessment and Penetration Testing are necessary processes that avert applications and systems from being hacked. The purpose of this study is to do vulnerability assessment and penetration testing understandable and present implementation techniques. Using Nikto and SQLMAP which are vulnerability assessment and penetration testing tools are presenting examples of VAPT in web applications. SQL Injection attacks take place in order to analysis their techniques and how vulnerabilities can lead on them.

description: We propose a novel mechanism for the production of dark matter (DM) from a thermal bath, based on the idea that DM particles $χ$ can transform heat bath particles $ψ$: $χψ\rightarrow χχ$. For a small initial abundance of $χ$ this leads to an exponential growth of the DM number density, in close analogy to other familiar exponential growth processes in nature. We demonstrate that this mechanism complements freeze-in and freeze-out production in a generic way, opening new parameter space to explain the observed DM abundance, and we discuss observational prospects for such scenarios.
