Encapsulation of T4 bacteriophage in electrospun biopolymers
Creators: name: Korehei, Reza
Publisher: name: University of British Columbia
Year: 2015

description: Packaging foods with antibacterial electrospun fibrous mats, in particular the incorporation of bacteria specific viruses such as bacteriophages may address concerns triggered by recent waves of bacterial food contamination. To this end several methods for incorporating or encapsulating T4 bacteriophage into electrospun fibres were investigated. The incorporation of T4 bacteriophage using simple suspension electrospinning lead to major losses in T4 bacteriophage activity, with more than five-orders of magnitude decrease in activity being observed. Improved T4 bacteriophage viability was obtained using two newly developed electrospinning processes, emulsion and coaxial electrospinning. In emulsion electrospinning, T4 bacteriophage was pre-encapsulated in an alginate reservoir via an emulsification process and subsequently electrospun into fibres. The emulsion electrospun fibres exhibited only two-orders of magnitude decrease in T4 bacteriophage activity. By contrast, complete T4 bacteriophage activity was maintained when coaxial electrospinning was employed. In the coaxial electrospinning process, a core/shell fibre structure was formed where the T4 bacteriophage was allocated to the fibre core, protected by the outer polymer shell. Depending on the polymer system used the rate of T4 bacteriophage release from the coaxial electrospun fibres varied. When hydrophilic poly(ethylene oxide) (PEO) was used as the polymer shell layer, immediate release of T4 bacteriophage was observed upon exposure to buffer. Increasing the PEO molecular weight increased the electrospun fibre diameter and viscosity of the releasing medium, which resulted in relatively slower T4 bacteriophage release pro-files. Similarly, the blending of cellulose diacetate (CDA) with PEO dramatically decreased the release behaviour. Depending on the PEO/CDA ratio, post-release electrospun fibre morphology varied from discontinuous fibres to minimally swollen fibres, consistent with the release profiles. In the PEO fibres the mechanism of T4 bacteriophage release is likely through solvent activa-tion/polymer dissolution, while in the PEO/CDA blends a more diffusion control mechanism likely prevails. The Encapsulation of T4 bacteriophage within the electrospun fibres also improved T4 bacteriophage storability; full T4 bacteriophage activity was maintained for more than a month at +4 °C, as compared to only hours for non-encapsulated phage. These results are significant in the context of controlling and preventing bacterial infections in perishable foods during refrigerated storage.

description: We study different patterns of interference in WIMP-nuclei elastic scattering that can accommodate the DAMA and CoGeNT experiments via an isospin violating ratio $f_n/f_p=-0.71$. We study interference between the following pairs of mediators: Z and Z', Z' and Higgs, and two Higgs fields. We show under what conditions interference works. We also demonstrate that in the case of the two Higgs interference, an explanation of the DAMA/CoGeNT is consistent with Electroweak Baryogenesis scenarios based on two Higgs doublet models proposed in the past.

description: Seit dem Jahr 2002 haben sozialversicherungspflichtig Beschäftigte einen Rechtsanspruch darauf, einen Teil ihres Arbeitsentgelts direkt steuer- und sozialabgabenfrei in eine betriebliche Altersvorsorge umzuwandeln (Entgeltumwandlung). Im Jahr 2014 haben etwa 19 Prozent der Beschäftigten in der Privatwirtschaft diese Möglichkeit genutzt und im Schnitt jährlich gut 1 300 Euro umgewandelt. Die Nutzung ist jedoch ungleich unter den Beschäftigten verteilt. Gerade Personen mit geringen Bruttolöhnen, Beschäftigte in kleinen Betrieben oder ohne Tarifvertrag nutzen die Entgeltumwandlung seltener. Die staatlich geförderte betriebliche Altersvorsorge, beispielsweise in Form der Entgeltumwandlung, könnte zum einen durch Förderung der finanziellen Bildung und Verbesserung der Anreize gestärkt werden. Denkbar wären eine verstärkte Unterstützung für Geringverdienende und eine vorgeschriebene Mindestbeteiligung der Arbeitgeber. Möchte man die Verbreitung schnell und weniger selektiv steigern, führt vermutlich kein Weg an einer verbindlichen betrieblichen Altersvorsorge vorbei. Allerdings stellen sich dabei weitreichende Gestaltungsfragen zur Umsetzung sowie der Verteilung von Lasten und Risiken.

description: Let $u(t)=-Fx(t)$ be the optimal control of the open-loop system $x'(t)=Ax(t)+Bu(t)$ in a linear quadratic optimization problem. By using different complex variable arguments, we give several lower and upper estimates of the exponential decay rate of the closed-loop system $x'(t)=(A-BF)x(t)$. Main attention is given to the case of a skew-Hermitian matrix $A$. Given an operator $A$, for a class of cases, we find a matrix $B$ that provides an almost optimal decay rate. We show how our results can be applied to the problem of optimizing the decay rate for a large finite collection of control systems $(A, B_j)$, $j=1, \dots, N$, and illustrate this on an example of a concrete mechanical system. At the end of the article, we pose several questions concerning the decay rates in the context of linear quadratic optimization and in a more general context of the pole placement problem.

description: This design-led research investigation focuses on architecture as a representation of cultural loss. Globalisation has spread Eurocentric modernist architectural principles across most cultures. In a very real sense, many Eastern cultures are having their own unique architectural histories rewritten, even erased, and are in danger of becoming lost. This investigation tests the methodology of using oral narrative (in this case, a series of superstitious Burmese tales from childhood) as a framing device to establish an architectural narrative about cultural loss in architecture. The research investigation reflects on the structure and semiotics derived from the abstraction of superstitions for challenging speculative architecture to give a voice to its own story about critical cultural loss. It reinterprets some of the most ‘ordinary’ Western elements of modern architecture – room, wall, ceiling, floor, threshold, window, etc. – through an Eastern lens, with the goal of obviating or reducing Western precepts. Eastern stories in the form of ‘oral narrative superstitions’ are used as provocateurs, starting points that help the project explicitly move away from traditional modernist architectural forms and relationships. The three design stages of the methodology progress iteratively: from physical analogue models derived from the abstraction of oral narrative superstitions; to digital animations as a narrative tool for reinterpreting these design ideas as shifts in spatial conditions over time; and finally, to the virtual gaming environment to enable agency in which the participants can construct their own experiential narrative outcomes.

description: Frustration has proved to give rise to an extremely rich phenomenology in both quantum and classical systems. The leading behavior of the system can often be described by an effective model, where only the lowest-energy degrees of freedom are considered. In this paper we study a system corresponding to the strong trimerization limit of the spin 1/2 kagome antiferromagnet in a magnetic field. It has been suggested that this system can be realized experimentally by a gas of spinless fermions in an optical kagome lattice at 2/3 filling. We investigate the low-energy behavior of both the spin 1/2 quantum version and the classical limit of this system by applying various techniques. We study in parallel both signs of the coupling constant J since the two cases display qualitative differences. One of the main peculiarities of the J>0 case is that, at the classical level, there is an exponentially large manifold of lowest-energy configurations. This renders the thermodynamics of the system quite exotic and interesting in this case. For both cases, J>0 and J<0, a finite-temperature phase transition with a breaking of the discrete dihedral symmetry group D_6 of the model is present. For J<0, we find a transition temperature T^0 the transition occurs at an extremely low temperature, T^>_c ~= 0.0125 J. Presumably this low transition temperature is connected with the fact that the low-temperature ordered state of the system is established by an order-by-disorder mechanism in this case.

description: Der Frauenanteil in Aufsichtsräten großer Unternehmen in Deutschland ist in den vergangenen Jahren gestiegen. Wie dieser zweite Teil des DIW Managerinnen-Barometers 2021 zeigt, wirkt sich das deutlich positiv auf die Interaktion, Diskussion und Entscheidungsfindung in den Kontrollgremien vieler Unternehmen aus. Das geht aus qualitativen Interviews mit 60 AufsichtsrätInnen hervor, die Mandate in insgesamt 75 börsennotierten Unternehmen in Deutschland innehaben. Sie betonen Veränderungen in der Atmosphäre, zudem werden Diskussionen als umfassender und facettenreicher beschrieben. Auch hinterfragen Frauen offenbar eher Vorschläge und Entscheidungen des Vorstandes und fordern öfter zusätzliche Informationen. Geschlechterdiversität in Aufsichtsräten kann daher dazu beitragen, Vorstände effektiver zu kontrollieren. Die Vorstellung, dass Frauen in Aufsichtsräten besonders risikoaverse, altruistische und ethische Beiträge machen, bestätigte sich nicht. Angesichts immer wieder auftretender Fälle von Betrug durch das Top-Management – wie im jüngsten prominenten Beispiel Wirecard – erscheint eine Verbesserung der Diskussion und Entscheidungsfindung in Aufsichtsräten enorm wichtig. In diesem Sinne besteht die Hoffnung, dass auch die jüngst vom Bundeskabinett beschlossene gesetzliche Vorgabe für eine Mindestbeteiligung von Frauen in Vorständen mehr als gleichstellungspolitische Impulse bewirkt

description: Die Frauenanteile in den Spitzengremien großer Unternehmen in Deutschland sind im vergangenen Jahr weiter gestiegen. In den 200 umsatzstärksten Unternehmen gab es im vierten Quartal des Jahres 2020 mit 101 Vorständinnen sieben mehr als ein Jahr zuvor. Hier wie auch in einigen anderen Unternehmensgruppen gewann die Entwicklung aber kaum an Dynamik. So lag der entsprechende Frauenanteil bei den Top-200-Unternehmen mit rund zwölf Prozent lediglich um gut einen Prozentpunkt höher als im Jahr zuvor. Bei den DAX-30-Unternehmen gab es sogar erstmals seit 2013 eine Stagnation. Schwung könnte die zu Beginn des Jahres vom Bundeskabinett beschlossene Mindestbeteiligung für Vor stände bringen: In ihrer jetzigen Ausgestaltung gilt sie für aktuell 74 Unternehmen, von denen etwa 30 sie noch nicht erfüllen. Tun sie dies, würde der Anteil der Vorständinnen in den unter die Regelung fallenden Unternehmen von etwa 13 auf 21 Prozent steigen. Zudem wären gleichstellungspolitische Impulse weit über die Vorstandsetagen hinaus möglich. Dass gesetzlich verbindliche Vorgaben wirken, unterstreicht die Entwicklung in den Aufsichtsräten.

description: We show that the galileons can be thought of as Wess-Zumino terms for the spontaneous breaking of space-time symmetries. Wess-Zumino terms are terms which are not captured by the coset construction for phenomenological Lagrangians with broken symmetries. Rather they are, in d space-time dimensions, d-form potentials for (d+1)-forms which are non-trivial co-cycles in Lie algebra cohomology of the full symmetry group relative to the unbroken symmetry group. We introduce the galileon algebras and construct the non-trivial (d+1)-form co-cycles, showing that the presence of galileons and multi-galileons in all dimensions is counted by the dimensions of particular Lie algebra cohomology groups. We also discuss the DBI and conformal galileons from this point of view, showing that they are not Wess-Zumino terms, with one exception in each case.

description: The social network maintained by a focal individual, or ego, is intrinsically dynamic and typically exhibits some turnover in membership over time as personal circumstances change. However, the consequences of such changes on the distribution of an ego's network ties are not well understood. Here we use a unique 18-month data set that combines mobile phone calls and survey data to track changes in the ego networks and communication patterns of students making the transition from school to university or work. Our analysis reveals that individuals display a distinctive and robust social signature, captured by how interactions are distributed across different alters. Notably, for a given ego, these social signatures tend to persist over time, despite considerable turnover in the identity of alters in the ego network. Thus as new network members are added, some old network members are either replaced or receive fewer calls, preserving the overall distribution of calls across network members. This is likely to reflect the consequences of finite resources such as the time available for communication, the cognitive and emotional effort required to sustain close relationships, and the ability to make emotional investments.

The Eternal Present of the Mythical Event: Re-establishing Place Identity with Speculative Installations that Reawaken Heritage Stories
Creators: name: Brown, Daniel
Publisher: name: Open Access Victoria University of Wellington | Te Herenga Waka
Year: 2021
Subjects: Uncategorized

description: This paper proposes that speculative architectural installations strategically ‘curated’ into neglected architectural contexts can help to engender an ‘immediate and a timeless realm,’ an encapsulation of a cultural story that the new interventions help to embody. The research method investigates historical and cultural narratives that were once associated with selected architectural and urban sites that have lost their place identity over time. Design-led research experiments examine how place identity can be rejuvenated by strategically curating objects, digital animation and sound into these architectural contexts in ways that bring their essential stories to life again, allowing cultural and heritage memories to be collectively experienced and shared. The research concludes that speculative architectural installations provide an opportunity to reach a much wider public audience than traditional academic scholarly approaches alone. Through community-based and collaborative creative practice, such architectural research can critically explore – and help to mediate and mitigate – seemingly intractable contemporary architectural problems such as the loss of cultural, heritage and place identity in our evolving urban environments. The research that looked at a derelict urban site in Rome played a significant role in convincing the Rome City Council that strategic application of cultural, mythological and historical experiences is a viable cost-effective way to culturally revitalise neglected and derelict public spaces.

description: We use simulations with realistic models for stellar feedback to study galaxy mergers. These high resolution (1 pc) simulations follow formation and destruction of individual GMCs and star clusters. The final starburst is dominated by in situ star formation, fueled by gas which flows inwards due to global torques. The resulting high gas density results in rapid star formation. The gas is self gravitating, and forms massive (~10^10 M_sun) GMCs and subsequent super-starclusters (masses up to 10^8 M_sun). However, in contrast to some recent simulations, the bulk of new stars which eventually form the central bulge are not born in superclusters which then sink to the center of the galaxy, because feedback efficiently disperses GMCs after they turn several percent of their mass into stars. Most of the mass that reaches the nucleus does so in the form of gas. The Kennicutt-Schmidt law emerges naturally as a consequence of feedback balancing gravitational collapse, independent of the small-scale star formation microphysics. The same mechanisms that drive this relation in isolated galaxies, in particular radiation pressure from IR photons, extend over seven decades in SFR to regulate star formation in the most extreme starbursts (densities >10^4 M_sun/pc^2). Feedback also drives super-winds with large mass loss rates; but a significant fraction of the wind material falls back onto the disks at later times, leading to higher post-starburst SFRs in the presence of stellar feedback. Strong AGN feedback is required to explain sharp cutoffs in star formation rate. We compare the predicted relic structure, mass profile, morphology, and efficiency of disk survival to simulations which do not explicitly resolve GMCs or feedback. Global galaxy properties are similar, but sub-galactic properties and star formation rates can differ significantly.

description: Die Corona-Pandemie hat weltweit zu einer schweren wirtschaftlichen Krise geführt. In vielen Ländern ist auch die Bauwirtschaft erheblich beeinträchtigt. In Deutschland hingegen zählt die Bautätigkeit zu den Wirtschaftszweigen mit bisher weitgehend stabilem Geschäft. So dürfte das gesamte Bauvolumen in Deutschland nach rund acht Prozent im vorvergangenen Jahr im Corona-Jahr 2020 nominal immer noch um vier Prozent auf gut 444 Milliarden Euro gestiegen sein. Für die Jahre 2021 und 2022 geht die neueste DIW Bauvolumenrechnung von einem Plus um fast drei beziehungsweise gut fünf Prozent aus. Dies liegt auch daran, dass – im Gegensatz zu anderen Ländern – die Arbeiten auf den Baustellen hierzulande weitergeführt werden dürfen und die Handwerksbetriebe ihre Aufträge in den Haushalten unter Hygieneauflagen erfüllen können. Dennoch macht sich die Krise auch für die Bauunternehmen bemerkbar: Vor allem der Wirtschaftsbau wird wohl einige Federn lassen. Wie der Nichtwohnungsbau insgesamt abschneidet, dürfte aber vor allem von der öffentlichen Hand abhängen. Werden wie bisher geplant die Investitionsausgaben von Bund und Ländern aufgestockt und die Löcher in den Haushalten der Kommunen gestopft, dürfte der öffentliche Bau die Bautätigkeit stabilisieren.

description: We investigate the transport of suspended Brownian particles dc driven along corrugated narrow channels in a regime of finite damping. We demonstrate that inertial corrections cannot be neglected as long as the width of the channel bottlenecks is smaller than an appropriate particle diffusion length, which depends on both, the temperature and the strength of the dc drive. Therefore, transport through sufficiently narrow constrictions turns out to be sensitive to the viscosity of the suspension fluid. Applications to colloidal systems are discussed.

description: We perform a density-matrix renormalization group (DMRG) study of the S=1/2 Heisenberg antiferromagnet on the kagome lattice to identify the conjectured spin liquid ground state. Exploiting SU(2) spin symmetry, which allows us to keep up to 16,000 DMRG states, we consider cylinders with circumferences up to 17 lattice spacings and find a spin liquid ground state with an estimated per site energy of -0.4386(5), a spin gap of 0.13(1), very short-range decay in spin, dimer and chiral correlation functions and finite topological entanglement gamma consistent with gamma=ld 2, ruling out gapless, chiral or non-topological spin liquids. At the same time, DMRG results provide strong evidence for a gapped topological Z2 spin liquid.

description: Beta decays of the isotones with N=126 are studied by shell model calculations taking into account both the Gamow-Teller (GT) and first-forbidden (FF) transitions. The FF transitions are found to be important to reduce the half-lives, by nearly twice to several times, from those by the GT contributions only. Possible implications of the short half-lives of the waiting point nuclei on the r-process nucleosynthesis during the supernova explosions are discussed. A slight shift of the third peak of the element abundances in the r-process toward higher mass region is found.

description: Identifying tectonically active faults and quantifying rates of movement is a key challenge in the Earth Sciences, in addition to this the interactions between active faulting and the landscape, specifically involving the fluvial network, is a relatively new area of study. Previous work has highlighted the value of understanding how the fluvial network responds to active tectonics, showing that a comprehensive understanding of the dynamic relationship between fluvial geomorphology and active tectonics is an important next step in geological research. This study presents new information about the poorly constrained Quaternary tectonic history of the Gediz Graben, Turkey, providing the first quantification of rates of movement of the key fault array that presently controlling graben topography. The fluvial network has been investigated and the data has been used in order to add resolution to the tectonic history for the fault array, allowing for the quantification of post-linkage throw rates. The study then investigates the key controls on the behaviour of the fluvial network that cross the active topography building fault array in the Gediz Graben. This study shows that there has been a linkage event occurring between 0.6 – 1 Ma, involving the three segments of the graben bounding fault array. The pre- and post-linkage throw rates are then extrapolated using data derived from the fluvial network, showing a faulting enhancement factor of 3 at the centre of the fault array, with the throw rate at the centre of the array predicted to have increased from a pre-linkage rate of 0.6 ± 0.1 mm/yr to a rate of 2 ± 0.2 mm/yr. This research provides evidence that the fluvial network can be used in conjunction with other types of evidence to provide a greater resolution tectonic history. Using both digital data and field studies this research presents an examination of the factors that influence the behaviour of bedrock rivers undergoing perturbation due to tectonics. Factors such as drainage area, tectonic throw rates and lithology have been investigated and the complicated interactions of these variables with the fluvial system have been quantified. This study shows that the bedrock rivers are a significant source of information about tectonics, but further work is needed to resolve quantitatively how various factors influence how rivers adjust to tectonic perturbation, in a variety of tectonic situations, in order to enable river to be used as a primary tool for deriving information about tectonics.

description: Finding vacua for the four dimensional effective theories for supergravity which descend from flux compactifications and analyzing them according to their stability is one of the central problems in string phenomenology. Except for some simple toy models, it is, however, difficult to find all the vacua analytically. Recently developed algorithmic methods based on symbolic computer algebra can be of great help in the more realistic models. However, they suffer from serious algorithmic complexities and are limited to small system sizes. In this article, we review a numerical method called the numerical polynomial homotopy continuation (NPHC) method, first used in the areas of lattice field theories, which by construction finds \textit{all} of the vacua of a given potential that is known to have only isolated solutions. The NPHC method is known to suffer from no major algorithmic complexities and is \textit{embarrassingly parallelizable}, and hence its applicability goes way beyond the existing symbolic methods. We first solve a simple toy model as a warm up example to demonstrate the NPHC method at work and compare the results with the available results from the symbolic methods. We then show that all the vacua of a more complicated model of M theory compactified on the coset $\frac{SU(3)\times U(1)}{U(1)\times U(1)}$, which has an SU(3) structure, can be obtained by the NPHC method using a desktop machine in just about one hour, a feat which was reported to be prohibitively difficult by the existing symbolic methods. Finally, we compare the various technicalities between the two methods.

description: Following the calculation of optimal energy transfer in thermal environment in our first paper (Wu et al., New J. Phys., 2010, 12, 105012), full quantum dynamics and leading-order `classical' hopping kinetics are compared in the seven-site Fenna-Matthews-Olson (FMO) protein complex. The difference between these two dynamic descriptions is due to higher-order quantum corrections. Two thermal bath models, classical white noise (the Haken-Strobl-Reineker model) and quantum Debye model, are considered. In the seven-site FMO model, we observe that higher-order corrections lead to negligible changes in the trapping time or in energy transfer efficiency around the optimal and physiological conditions (2% in the HSR model and 0.1% in the quantum Debye model for the initial site at BChl 1). However, using the concept of integrated flux, we can identify significant differences in branching probabilities of the energy transfer network between hopping kinetics and quantum dynamics (26% in the HSR model and 32% in the quantum Debye model for the initial site at BChl 1). This observation indicates that the quantum coherence can significantly change the distribution of energy transfer pathways in the flux network with the efficiency nearly the same. The quantum-classical comparison of the average trapping time with the removal of the bottleneck site, BChl 4, demonstrates the robustness of the efficient energy transfer by the mechanism of multi-site quantum coherence. To reconcile with the latest eight-site FMO model, the quantum-classical comparison with the flux network analysis is summarized in the appendix. The eight-site FMO model yields similar trapping time and network structure as the seven-site FMO model but leads to a more disperse distribution of energy transfer pathways.
