Implications of the Stability and Triviality Bounds on the Standard Model with Three and Four Chiral Generations
Creators: name: Wingerter, Akin

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We revisit the stability and triviality bounds on the Higgs boson mass in the context of the Standard Model with three and four generations (SM3 and SM4, respectively). In light of the recent results from LHC the triviality bound in the SM3 has now become obsolete, and the stability bound implies for a Higgs mass of e.g. mH=115 GeV the onset of new physics before 650 TeV, whereas there are no limits for mH>133 GeV. For the SM4, the stability and triviality curves intersect and bound a finite region. As a consequence, the fourth generation fermions place stringent theoretical limits on the Higgs mass, and there is a maximal scale beyond which the theory cannot be perturbatively valid. We find that the Higgs mass cannot exceed 700 GeV for any values of the fourth generation fermion masses. Turning the argument around, the absence of a Higgs signal for mH<600 GeV excludes a fourth generation with quark masses below 300 GeV and lepton masses below 350 GeV. In particular, the quark bounds also hold for the small mixing scenarios for which the direct limits from Tevatron and LHC are not applicable, and the lepton bounds we obtain are stronger than the collider limits. If a Higgs boson lighter than 700 GeV is not observed, a fourth generation of chiral fermions with perturbative Yukawa couplings will be conclusively excluded for the full range of parameters.

An investigation of hydrodynamic conditions inside gas-sparged hollow fiber membrane modules
Creators: name: Chan, Colleen C. V.
Publisher: name: University of British Columbia
Year: 2010

description: Over the past decade, membrane filtration has emerged as a proven technology for water and wastewater treatment applications. Despite its popularity, the problem of membrane fouling remains the Achilles heel of membrane filtration. A common strategy to control membrane fouling is the use of gas sparging to prevent particle deposition on membrane surfaces. The efficiency of gas sparging for fouling control/prevention depends on the effective distribution of sparged gas bubbles and bubble-induced flow across membrane surfaces. To date, there is very limited literature available that describes this hydrodynamic condition inside the submerged hollow fiber membrane modules. The reason for this limited knowledge is the complex and transient nature of the geometry and hydrodynamics inside hollow fiber modules. The hydrodynamic conditions surrounding a hollow fiber under gas sparging, and the relationship between hydrodynamic conditions and fouling control are not well understood. This presents an obstacle to optimizing the performance of submerged hollow fiber modules with respect to energy costs associated with gas sparging. This thesis provides a comprehensive study of the hydrodynamic conditions inside a gas-sparged submerged hollow fiber membrane module, and the relationship between the observed hydrodynamic conditions and fouling control. Unlike what had been hypothesized by some, the results indicated that the hydrodynamic conditions inside a submerged hollow fiber membrane are different than those of confined tubular membrane systems. It was also observed that different types of shear profiles exist inside the membrane module, and the different types of shear conditions result in different fouling, which suggests that different mechanisms are at play in controlling particle transport near the membrane surface. This information opens the opportunity for further investigation in terms of optimization of the gas –sparging system, or other shear-generating devices that create shear conditions that offer the greatest benefit minimizing fouling, while minimizing the energy demand associated with generating these shear conditions.

Subjects: subject: Longlining (Fisheries)--Monitoring--Hawaii.

description: The following tables represent effort, retained catch (kept) and discard as reported on longline log sheets for the Hawaii limited-access longline fishery. To satisfy confidentiality RFMO reporting standards, data from the California-based longline fishery is also included in this report. Catch-and-effort statistics are summarized from logbook data submitted to the PIFSC report. Catch-and-effort statistics are summarized from logbook data submitted to the PIFSC FRMD and are based on date of longline haul. The statistics originate from an Oracle table LLDS_REPORT_STATS_HICA database extraction done on 3 May 2016. When a statistic (number of vessels, trips) can involve dates of haul in 2 summary periods (i.e. years, semi-annual, quarters) the item is counted in both summary periods. Thus, a trip total is for "partial and completed" trips. As such, these are not additive statistics (i.e. sum of 4 quarters is not the total for the year, etc).

description: Many well-established classification algorithms such as support vector machines (SVM) are originally proposed as large-margin classifiers from a single hyperplane. This dissertation is divided into two halves, each half studying classification from the perspective of using multiple hyperplanes. The first half introduces a new framework for multiclass loss functions called the permutation-equivariant and relative margin-based (PERM) losses, inspired by multiclass classification with multiple hyperplanes. Using our framework, we establish statistical and optimization results on Weston-Watkins multiclass SVMs. Furthermore, we provide sufficient conditions for the classification-calibration of a general family of PERM losses. These sufficient conditions subsume all previously known and establish new classification-calibration results. The second half focuses on hyperplane arrangement classifiers (HACs). When implemented as neural networks, we show that the HACs can be overparameterized yet still have small VC dimensions and further achieve minimax optimality (assuming the empirical risk minimization can be solved to optimality). By using an ensemble of randomly initialized HACs, we demonstrate for the first time an interpolating ensemble method that is consistent for a broad class of distributions in arbitrary dimensions. We discuss the significance of these results in the context of recent advances in the theory of overparameterized learning.

description: Continuous-time discrete-state random Markov chains generated by a random linear differential equation with a random tridiagonal matrix are shown to have a random attractor consisting of singleton subsets, essentially a random path, in the simplex of probability vectors. The proof uses comparison theorems for Carathéodory random differential equations and the fact that the linear cocycle generated by the Markov chain is a uniformly contractive mapping of the positive cone into itself with respect to the the Hilbert projective metric. It does not involve probabilistic properties of the sample path and is thus equally valid in the nonautonomous deterministic context of Markov chains with, say, periodically varying transitions probabilities, in which case the attractor is a periodic path.

description: In this paper, we study the interplay between modules and sub-objects in holomorphic Poisson geometry. In particular, we define a new notion of "residue" for a Poisson module, analogous to the Poincaré residue of a meromorphic volume form. Of particular interest is the interaction between the residues of the canonical line bundle of a Poisson manifold and its degeneracy loci---where the rank of the Poisson structure drops. As an application, we provide new evidence in favour of Bondal's conjecture that the rank \leq 2k locus of a Fano Poisson manifold always has dimension \geq 2k+1. In particular, we show that the conjecture holds for Fano fourfolds. We also apply our techniques to a family of Poisson structures defined by Fe\uıgin and Odesski\uı, where the degeneracy loci are given by the secant varieties of elliptic normal curves.

description: In order to obtain a well-defined path integral one often employs discretizations. In the case of General Relativity these generically break diffeomorphism symmetry, which has severe consequences since these symmetries determine the dynamics of the corresponding system. In this article we consider the path integral of reparametrization invariant systems as a toy example and present an improvement procedure for the discretized propagator. Fixed points and convergence of the procedure are discussed. Furthermore we show that a reparametrization invariant path integral implies discretization independence and acts as a projector onto physical states.

A probabilistic approach for estimating environmental impacts over the life cycle of buildings
Creators: name: Guerra Castrejón, Edwin Alfredo
Publisher: name: University of British Columbia
Year: 2010

description: There is increased awareness and concern regarding human activities with high environmental impacts caused by the construction, operation, maintenance and decommissioning of the built environment. The work presented in this thesis helps predict holistically the environmental impact indicators of different building design options. A probabilistic framework, applicable to multiple building function types, is proposed to estimate the environmental metrics of energy, water and global warming potential. The environmental impact indicators are studied at varying resolutions of data quality. The proposed framework differs from alternate tools by explicitly accounting for uncertainty through the use of random variables in its models. The modeling approach emphasizes greater transparency of the environmental impact intensity values that relate known information about the building, such as material quantities, with respective environmental impacts. Explicit environmental impact models are presented for each of the building’s life cycle phases, including extraction, manufacture, on-site construction, operation, maintenance, and end of life. The methodology is then demonstrated by analyzing a sample residence in Ontario. The environmental impacts associated with the entire life cycle of the building are reported and possible improvements to the methodology are identified. The ability to analyze the probability of exceeding an environmental impact threshold is a feature of this work that is useful in the refinement of environmental performance rating systems. The general lack of public information about the environmental impact of the manufacturing of building components in North America, as well as uncertainty about component replacement frequency and the building service life continue to pose a challenge for environmental impact analysis. However, this thesis presents a new probabilistic framework in which this uncertainty is explicitly identified and addressed.

description: Στη μελέτη αυτή εξετάζεται το φαινόμενο των μαγικών φυλακτών και η αντιμετώπιση τους από το κράτος, την Εκκλησία και το λαό κατά τη βυζαντινή περίοδο. Για να καταστεί αυτό δυνατό, τα μαγικά φυλακτά προσεγγίζονται μέσα από τη μαρτυρία των γραπτών πηγών της Ύστερης Αρχαιότητας και του Μεσαίωνα, του υλικού κατασκευής, των εικονογραφικών θεμάτων και των επιγραφών που φέρουν, ώστε να γίνει κατανοητός ο τρόπος με τον οποίο χρησιμοποιούνταν. Ιδιαίτερη έμφαση δίνεται στα μαγικά φυλακτά από ανασκαφικές θέσεις και τα συνευρήματα τους, με στόχο την κατανόηση της ταυτότητας των παραγγελιοδοτών/φερόντων και των αντιλήψεων που επικρατούσαν για τα μαγικά φυλακτά.

Στο πρώτο εξετάζονται μαρτυρίες σχετικά με τα φυλακτά και τις μαγικές πρακτικές σε επίσημες και ανεπίσημες γραπτές πηγές της Ύστερης Αρχαιότητας και των βυζαντινών κυρίως χρόνων (νομοθετικά διατάγματα, κείμενα των Πατέρων της Εκκλησίας, ιστορικά κείμενα, πραγματείες ιατρών της Ύστερης Αρχαιότητας και γραπτές πηγές μαγικού περιεχομένου). Στο δεύτερο κεφάλαιο εξετάζονται τα μαγικά φυλακτά ως προς το υλικό κατασκευής τους, τα εικονογραφικά θέματα και τις επιγραφές τους. Τέλος, στο τρίτο κεφάλαιο μελετώνται αφενός τα μαγικά φυλακτά των οποίων γνωρίζουμε την προέλευση και αφετέρου τα φυλακτά που εντοπίστηκαν σε ανασκαφικά στρώματα.
description: This study focuses on magical amulets and their treatment by the state, the Church and the people during the Byzantine period. Thus, magical amulets are studied through the evidence of Late antique and Medieval written sources, their construction material, the iconographic themes and the inscriptions they bear, in order to understand how they were. Particular emphasis is given on magical amulets from excavations, aiming at understanding the identity of the bearer and people’s perceptions regarding magical amulets. An effort for a better dating of the amulets thanks to their archaeological context is also made. The study is divided into three chapters. The first chapter deals with Late antique and Byzantine official and unofficial written sources legislative texts, texts of the Fathers of the Church and Byzantine historians, discourses of the Late antique doctors, and written sources of magical content). In the second chapter, magical amulets are examined according to their materials, iconography, and inscriptions. The last chapter, focuses on the one hand magical amulets of known provenance an on the other hand on magical amulets found in archaeological excavations.

description: Student interest in Synthetic Biotechnology is noticeable and exponential.Synthetic Biotechnology is an emerging scientific field that focuses on thedesign and fabrication of living organisms that do not already exist in thenatural world for useful purposes. Training on Synthetic Biotechnology ishighly interdisciplinary through research-informed specialized courses andpractical exposure to industrial internships. Each year students from around theworld participate in the International Genetically Engineered Machine (iGEM),a summer long Synthetic Biotechnology competition. As part of their iGEMexperience, students design and construct novel living organisms usingadvanced genetic engineering techniques.
One Synthetic Biotechnology feat was accomplished recently by an iGEMteam, who modified the normally putrid smell of bacteria so that the cellsgenerated pleasant scents. We have taken advantage of their studies as well asother iGEM successes and recent research publications to develop a teachingcurriculum for our courses in Biology, Chemistry, Medical and BiomedicalEngineering. The curriculum includes hands-on activities and classroomassignments. We envision these activities either complementing existinginstruction or replacing some outdated cookbook lab classes that are often usedas gateways to undergraduate teaching. The activities that have been developedalso introduce engineering, technology and bio-entrepreneurship concepts thatare often overlooked in the already over-stuffed college curricula. To ease theiradoption, the activities include lecturer materials, such as annotated instructionsand animated resources. In this presentation, details regarding the student andlecturer materials for creating genetically engineered banana-scented bacteria toteach Medical, Industrial and Environmental Biotechnology will be presented.
Modelling Authenticity in Science Education

Publisher: name: Springer

Subjects: disciplinary authenticity, personal authenticity, real-world authenticity, contextualisation

description: The terms 'authenticity' and 'authentic' have been used increasingly frequently in educational contexts over the past decades. In science education, authenticity is claimed to be a crucial concept, inter alia, for students' motivation and interest in science. However, both terms are used, defined and conceptualised in various and ambiguous ways. So far, however, a model to integrate and structure the various conceptualisations, definitions and findings with their implementation in a teaching context is lacking. In this contribution, we introduce such a model, coherently integrating a broad range of work done by previous authors. Meanwhile, the model is flexible enough for future extensions and refinements. As many authors have shown, the concept of authenticity is multidimensional. In the present contribution, we therefore introduce a multidimensional model, explaining each dimension with reference to previous work on authenticity before integrating them as the complete model. We will outline a tool for practitioners and researchers which is based on the introduced model.

description: The judgment of the Grand Chamber in Al-Dulimi and Montana Management Inc. v. Switzerland can be praised as an effort to avoid contradictions between the UN Charter and the European Convention of Human Rights. It is also a reminder that UN Sanctions Committees still fail to meet fair trial standards. However, the reasoning of the Grand Chamber is not beyond controversy. In justifying the lack of contradiction between the SC Resolution 1483 (2003) and the ECHR, the Grand Chamber relies on a presumption of harmony between two legal orders (the UN Charter and the Convention) that is open to discussion. Moreover, the application made in casu of such presumption is unconvincing, since it does not appear to be supported by other elements of inter-pretation.

description: The Uhrig dynamical decoupling sequence achieves high-order decoupling of a single system qubit from its dephasing bath through the use of bang-bang Pauli pulses at appropriately timed intervals. High-order decoupling of single and multiple qubit systems from baths causing both dephasing and relaxation can also be achieved through the nested application of Uhrig sequences, again using single-qubit Pauli pulses. For the 3-qubit decoherence free subsystem (DFS) and related subsystem encodings, Pauli pulses are not naturally available operations; instead, exchange interactions provide all required encoded operations. Here we demonstrate that exchange interactions alone can achieve high-order decoupling against general noise in the 3-qubit DFS. We present decoupling sequences for a 3-qubit DFS coupled to classical and quantum baths and evaluate the performance of the sequences through numerical simulations.

description: In the context of this research, the synthesis of a series of N-(pyridin-2-yl)iminonitriles was conducted, following a simple synthetic protocol in which the starting materials were substituted and unsubstituted 2-aminopyridines and nitrostyrenes, in the presence of the acidic catalyst Al2O3. Subsequently, these α-iminonitriles were transformed into the corresponding N-(pyridin-2-yl)imidates, through a simple and under mild reaction conditions methodology, in the presence of a base (Cs2CO3) and in alcoholic media at room temperature. Many of these products were isolated in good yields and synthesized for the first time in the literature. In parallel, a preliminary synthetic application of these imidates as intermediates was studied for the conversion into the N,N-heterocyclic compounds, such as 4,5-dihydro-1H-imidazoles and 1,4,5,6-tetrahydropyrimidines, in the presence of diamines.

description: We present deep 1.8 cm (16 GHz) radio continuum imaging of seven young stellar objects in the Taurus molecular cloud. These objects have previously been extensively studied in the sub-mm to NIR range and their SEDs modelled to provide reliable physical and geometrical parametres.We use this new data to constrain the properties of the long-wavelength tail of the greybody spectrum, which is expected to be dominated by emission from large dust grains in the protostellar disk. We find spectra consistent with the opacity indices expected for such a population, with an average opacity index of beta = 0.26+/-0.22 indicating grain growth within the disks. We use spectra fitted jointly to radio and sub-mm data to separate the contributions from thermal dust and radio emission at 1.8 cm and derive disk masses directly from the cm-wave dust contribution. We find that disk masses derived from these flux densities under assumptions consistent with the literature are systematically higher than those calculated from sub-mm data, and meet the criteria for giant planet formation in a number of cases.

description: We show that the magnetic susceptibility of a dilute ensemble of magnetic impurities in a conductor with a relativistic electronic spectrum is non-analytic in the inverse tempertature at $1/T\to 0$. We derive a general theory of this effect and construct the high-temperature expansion for the disorder averaged susceptibility to any order, convergent at all tempertaures down to a possible ordering transition. When applied to Ising impurities on a surface of a topological insulator, the proposed general theory agrees with Monte Carlo simulations, and it allows us to find the critical temperature of the ferromagnetic phase transition.

description: Η παρούσα εργασία αναφέρεται στον Άγιο Ιουστίνο τον φιλόσοφο και μάρτυ ως εισηγητή της έννοιας του σπερματικού λόγου. Σκοπό της αποτέλεσε ο εντοπισμός ομοιοτήτων και διαφορών μεταξύ της φιλοσοφίας και ειδικότερα των στωϊκών, με τη χριστιανική διδασκαλία των πρώτων μεταχριστιανικών αιώνων. Λάβαμε υπόψη τις φιλοσοφικές και γνωστικές τάσεις της εποχής, αν και σε πρώιμο στάδιο, η οποία χαρακτηρίζεται από εντάσεις μεταξύ διάφορων θρησκειών και διωγμών κατά των χριστιανών. Τα κείμενα του Αγίου αποτελούν σταθμό στη χριστιανική διδασκαλία και για αυτό θεωρείται ο πρώτος χριστιανός φιλόσοφος. Στους απολογητικούς διαλόγους του συνυπάρχουν με διακριτό ρόλο η ελληνική φιλοσοφία και ο χριστιανισμός, μια αναντίρρητα σπουδαία παρακαταθήκη για τους μεταγενέστερους πατέρες της Εκκλησίας. Στη μελέτη μας κυριαρχούν οι δύο απολογίες, οι οποίες απευθύνονται στον Μάρκο Αυρήλιο και ο μνημειώδης διάλογος με τον Ιουδαίο Τρύφωνα. Ειδικότερα, στον τελευταίο αντλούμε πολλά στοιχεία για το φιλοσοφικό υπόβαθρο του Απολογητού και την θεολογική μεθοδολογία του, η οποία παρουσιάζεται με τους κανόνες της φιλοσοφίας και του ορθού λόγου. Στη συνέχεια, γίνεται μια μικρή αναφορά στην αρχαία ελληνική φιλοσοφία, τις θεωρίες περί του Θεού, του κόσμου και των μεταξύ τους θέσεων.
description: The present work refers to Saint Justin the philosopher and martyr as the introducer of the concept of the spermatic logos (seminal word). Its purpose was to identify similarities and differences between philosophy, especially Stoic philosophy, with the Christian teaching of the first post-Christian centuries. We took into account the philosophical and cognitive trends of the era, albeit at an early stage, which was characterized by tensions between various religions and persecutions against Christians. The texts of the Saint are a milestone in Christian teaching and for this reason he is considered the first Christian philosopher. In his apologetic dialogues Greek philosophy and Christianity co-exist with a distinct role, an undeniably great legacy for the later fathers of the Church. Our study is dominated by the two Apologies, which are addressed to Marcus Aurelius and the monumental dialogue with Tryphon the Jew. In particular, in the latter we derive a lot of information about the philosophical background of the Apologist and his theological methodology, which is presented with the rules of philosophy and correct discourse. Then, a small reference is made to ancient Greek philosophy, the theories about God, the world and the points of view between them.

description: Language learning and acquisition constitute – or at least should constitute – the most important factors in the preparation of teaching materials and lesson plans. As previous research studies have clearly indicated, regular revision and recycling of the linguistic elements and structures that the learners encounter through formal instruction are essential in order to ensure language learning and acquisition. This study aims to find out whether current textbooks on the market incorporate these previous research findings, assisting language learning and acquisition, or ignore these findings, inhibiting in this way the learning process. As the contribution of corpus linguistics in issues of foreign language learning is nowadays widely acknowledged, the present study is based on an analysis of data drawn from the pedagogic corpora which have been particularly constructed for the purposes of this paper.
description: Ελληνική Περίληψη Η εκμάθηση και η κατάκτηση μιας γλώσσας αποτελούν – ή τουλάχιστον πρέπει να αποτελούν – τους σημαντικότερους παράγοντες στην προετοιμασία του διδακτικού υλικού και ενός πλάνου μαθήματος. Όπως έχουν δείξει ξεκάθαρα προηγούμενες ερευνητικές μελέτες, η τακτική αναθεώρηση και ανακύκλωση των γλωσσικών στοιχείων και δομών που αντιμετωπίζουν οι εκπαιδευόμενοι μέσω της επίσημης διδασκαλίας είναι ουσιαστικής σημασίας προκειμένου να διασφαλιστεί η εκμάθηση και η απόκτηση της γλώσσας. Αυτή η μελέτη στοχεύει να ανακαλύψει εάν τα τρέχοντα εγχειρίδια στην αγορά ενσωματώνουν αυτά τα προηγούμενα ερευνητικά ευρήματα, βοηθώντας την εκμάθηση και την απόκτηση γλωσσών ή αγνοούν αυτά τα ευρήματα, δυσχεραίνοντας με αυτόν τον τρόπο τη μαθησιακή διαδικασία. Καθώς η συμβολή της γλωσσικών σωμάτων κειμένων (corpora) σε θέματα εκμάθησης ξένων γλωσσών αναγνωρίζεται ευρέως στις μέρες μας, η παρούσα μελέτη βασίζεται σε ανάλυση δεδομένων που προέρχονται από γλωσσικά σώματα τα οποία δημιουργήθηκαν αποκλειστικά για τους σκοπούς της παρούσας εργασίας

description: In dieser Studie haben wir untersucht, ob das Spielen eines Escape-Room-Spiels nach expliziter Anweisung (Instruction-First-Gruppe, N = 20) effektiver ist, um etwas über Urheber- und Medienrecht zu lernen, als das Spiel vor expliziter Anleitung zu spielen (Problem-Solving-First-Gruppe, N = 21). Dies ist eine wichtige Frage, da Escape Room Games komplexe, problembasierte Lernumgebungen sind, die die Lernenden überfordern und somit den Erwerb von Wissen und Fähigkeiten behindern können. Nach der kognitiven Belastungstheorie kann die Vorbereitung der Lernenden mit expliziten Anweisungen vor Problemlösungsaktivitäten dieses Problem überwinden, was zu einem besseren Lernen führt. Im Product-Failure-Paradigma wird jedoch die Problemlösung vor expliziter Anleitung als effektiver angesehen, insbesondere wenn es um die Anwendung neu erworbenen Wissens zur Lösung neuartiger Probleme geht. Basierend auf diesen beiden Theorien führten wir ein Experiment durch und stellten fest, dass das Spielen des entwickelten digitalen Escape Room Spiels nach expliziter Anleitung effektiver für Wissenserhalt und domänenspezifische Selbstwirksamkeit bei gleichzeitig geringerer kognitiver Belastung war. Wir fanden jedoch keine Unterschiede in der Anwendung von Wissen, da beide Gruppen bei Transferaufgaben gleich gut abschnitten. Das Ergebnis wird unter Berücksichtigung früherer produktiver Fehlerstudien diskutiert, die hauptsächlich im Bereich Wissenschaft und Technik durchgeführt wurden. Zusammenfassend erwies sich der Instruction First-Ansatz sowohl für den Wissenserwerb als auch für die Wissensanwendung als effektiv, was zu einer höheren domänenspezifischen Selbstwirksamkeit und einer geringeren kognitiven Belastung führte. Daher kommen wir zu dem Schluss, dass die Implementierung von Escape Room Games nach dem Unterricht ein effektiver Unterrichtsansatz ist und besser geeignet ist, das Lernen zu fördern, als Escape Room Spiele vor dem Unterricht zu spielen.

description: Background: The vestibular system provides a comprehensive estimate of self-motion in 3D space. Widely used to artificially stimulate the vestibular system, binaural-bipolar square-wave Galvanic Vestibular Stimulation (GVS) elicits a virtual sensation of roll rotation. Postural responses to GVS have been clearly delineated, however quantifying the perceived virtual rotation vector has not been fully realised. Objective: We aimed to quantify the perceived virtual roll rotation vector elicited by GVS using a psychophysical approach on a 3D turntable. Methods: Participants were placed supine on the 3D turntable and rotated around the naso-occipital axis while supine and received square-wave bipolar-binaural GVS or sham stimulation. GVS amplitudes and intensities were systematically manipulated. The turntable motion profile consisted of a velocity step of 20°/s2 until the trial velocity between 0-20°/s was reached, followed by a 1°/s ramp until the end of the trial. In a psychophysical adaptive staircase procedure, we systematically varied the roll velocity to identify the exact velocity that cancelled the perceived roll sensation induced by GVS. Results: Participants perceived a virtual roll rotation towards the cathode of approximately 2o/s velocity for 1 mA GVS and 6o/s velocity for 2.5 mA GVS. The observed values were stable across repetitions. Conclusions: Our results quantify for the first time the perceived virtual roll rotations induced by binaural-bipolar square-wave GVS. Importantly, estimates were based on perceptual judgements, in the absence of motor or postural responses and in a head orientation where the GVS-induced roll sensation did not interact with the perceived direction of gravity. This is an important step towards applications of GVS in different settings, including sensory substitution or Virtual Reality.

Comparison of nitrification activity in membrane and conventional enhanced biological phosphorus removal processes

description: While research is conclusive that the membrane bioreactor process performance in removing the carbonaceous and phosphorus constituents of wastewater is superior or equivalent to a conventional gravity separation process, there have been conflicting reports regarding its ability to achieve nitrification rates comparable to the conventional process. In this long-term study conducted at University of British Columbia’s (UBC’s) wastewater treatment pilot plant facility, the specific nitrification activity of a membrane enhanced biological phosphorus removal (EBPR) process was compared to that of a conventional EBPR process operating under identical conditions to identify factors that influence the relative nitrification rate of the processes. The specific nitrification rate measured from batch experiments showed a natural variation between the processes. There were periods where the specific nitrification rate of the membrane process was either consistently high or consistently low, relative to the conventional process. Average rates were nearly equal, however, the membrane process showed less variability in the individual rates. Nitrifier decay rates measured during the various performance periods conformed to the variation observed as rates for the membrane process were lower relative to the conventional process during periods where the specific nitrification rate for the membrane process was higher and vice versa. The presence of rotifers caused an increase in the decay rate of the conventional process. These organisms were absent in the membrane process. Vigorous coarse bubble aeration did not affect the decay rate. Terminal restriction fragment length polymorphisms (T-RFLP) analysis showed that ammonia-oxidizing (AOB) communities differed for the two processes, however the nitrite-oxidizing bacteria (NOB) communities as represented by the genus Nitrobacter and Nitrospira were similar for both processes. Temperature effects were significant for both AOB and NOB communities, but the effect was greater for the AOB community. Community shifts for the AOB were observed to occur during plant operation. Quantification of the nitrifiers by a real time polymerase chain reaction assay indicated similar quantities of AOB, Nitrobacter and Nitrospira in the two processes with Nitrospira being the most abundant of the nitrifiers present in the systems. AOB and Nitrobacter quantities correlated with the relative nitrification rate of the processes.
