A Stochastic Representation of Temperature Fluctuations Induced by Mesoscale Gravity Waves
Creators: name: Kärcher, B.
name: Podglajen, A.
Publisher: name: FID GEO
Year: 2019

description: Ubiquitous mesoscale gravity waves generate high cooling rates important for cirrus formation. We make use of long-duration balloon observations to devise a probabilistic model describing mesoscale temperature uctuations (MTF) away from strong wave sources. We define background conditions based on observed probability distributions of temperature and underlying vertical wind speed fluctuations. We show theoretically that MTF are subject to damping at a rate near the Coriolis frequency when the vertical wind speed fluctuations are autocorrelated over a fraction of a Brunt-Väisälä period. We find that for background wave activity, a decrease in temperature of 1K translates into cooling rate standard deviations and mean updraft speeds of 4–8Kh−1 and ≈ 10–20 cms−1, respectively, depending on latitude and stratification. We introduce an effective Coriolis frequency to generate cooling rates in equatorial regions consistent with balloon data. Above ice saturation, MTF are large enough to affect ice crystal nucleation. Our results help constrain uncertainty in aerosol-cirrus interactions, provide insights to better meet challenges in comparing measurement data with model simulations, and support the development of cutting-edge ice cloud schemes in global models.
Theoretical foundations for optimal control of floating offshore wind farms
Creators: name: Cherom Kheirabadi, Ali
Publisher: name: University of British Columbia
Year: 2021

description: Due to a phenomenon termed the wake effect, wind turbines that are placed in close proximity within wind farms interact aerodynamically. In short, each turbine generates a wake within which wind speeds are reduced, and these wakes overlap with the rotors of machines located downstream. This interaction diminishes power production in wind farms by up to 60%. Using a process referred to as wind farm control, individual wind turbines may be operated in a manner that increases power production from the collective. This thesis investigates the potential of a wind farm control strategy named yaw and induction-based turbine repositioning (YITuR) that is specifically compatible with floating offshore wind farms. Since floating platforms are anchored to the seabed using slack mooring line cables, each turbine may be repositioned in real-time using the aerodynamic forces exerted on its rotor. By relocating floating platforms accordingly, the overlap area between the wakes generated by upstream turbines and the rotors of downstream machines may be reduced; leading to an increase in wind farm efficiency. The potential of YITuR is assessed through several steps. First, a steady-state model of floating offshore wind farms is constructed and stationary optimization studies are carried out to determine the potential of YITuR under idealized steady wind conditions. Major findings from this study are that wind farm efficiency may increase by more than 40% using YITuR over traditional wind farm operation; however, these benefits are strongly influenced by mooring system designs. Second, a dynamic floating wind farm model is developed to evaluate the performance of real-time control systems. Third, due to the non-convexity of the YITuR control problem, novel distributed economic model predictive control (DEMPC) theory is developed to guarantee power maximization. Existing DEMPC algorithms do not offer such a guarantee in the presence of non-convex objective functions. Finally, the DEMPC algorithm is evaluated using the dynamic simulation tool. Neural networks are used to estimate the dynamics of floating platforms in order to expedite decision-making in DEMPC. Simulation results indicate gains of 20% in energy production when YITuR replaces traditional wind farm operation.

description: We present the compilation and properties of a Meta-Catalogue of X-ray detected Clusters of galaxies, the MCXC. This very large catalogue is based on publicly available ROSAT All Sky Survey-based (NORAS, REFLEX, BCS, SGP, NEP, MACS, and CIZA) and serendipitous (160SD, 400SD, SHARC, WARPS, and EMSS) cluster catalogues. Data have been systematically homogenised to an overdensity of 500, and duplicate entries originating from overlaps between the survey areas of the individual input catalogues are carefully handled. The MCXC comprises 1743 clusters with virtually no duplicate entries. For each cluster the MCXC provides: three identifiers, a redshift, coordinates, membership of original catalogue, and standardised 0.1-2.4 keV band luminosity L_500, total mass M_500, and radius R_500. The meta-catalogue additionally furnishes information on overlaps between the input catalogues and the luminosity ratios when measurements from different surveys are available, and also gives notes on individual objects. The MCXC is available in electronic format for maximum usefulness in X-ray, SZ, and multi-wavelength studies.
description: A&A submitted, 17 pages, the MCXC catalogue will be available upon acceptance of the paper
Un viaggio dentro l’abito. Gattinoni: settant’anni di storia nella Haute Couture
Creators: name: Fidanza, Vieri
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2017

description: L’Alta Moda è quella tipologia di abbigliamento che si colloca nell’ambito dei beni di lusso. È un settore molto complesso, che si avvale di differenti figure professionali come stilisti, disegnatori, specialisti di marketing ed esperti di comunicazione. Nell’immaginario collettivo richiama le passerelle, le luci della ribalta, le copertine dei fashion magazine e uno stile di vita particolare e pretenzioso. All’Alta Moda appartengono, però, anche altri luoghi più reconditi, celati, che pochi conoscono. Sono gli archivi delle “maison”, all’interno dei quali si conservano gli abiti delle stagioni trascorse, i bozzetti, le immagini e tutti i materiali inerenti al passato, recente e remoto, della vita di ogni griffe. Sono luoghi che vengono vissuti nel mito della segretezza, dove si conservano tesori accessibili a pochissime persone. Spesso i materiali conservati non sono catalogati, ma la loro importanza è fondamentale, perché costituiscono la memoria storica dei marchi di Haute Couture. L’archivio diviene allora il patrimonio delle case di moda, un vero e proprio “heritage” che rappresenta il loro valore storico. L’obiettivo del progetto “Un viaggio dentro l’abito” consiste nella presentazione dell’archivio dedicato all’Alta Moda della maison Gattinoni di Roma, attraverso una reinterpretazione visiva in chiave attuale delle creazioni che costituiscono il percorso di settant’anni della casa di moda italiana. La ricerca è stata resa possibile dall’opportunità di accedere, senza alcuna restrizione, a tutti i materiali dell’archivio, dai più datati ai più recenti, in modo da sviluppare un approfondimento storico e critico del brand Gattinoni, possibile solo basandosi su tutta la documentazione esistente. L’indagine non ha trascurato gli aspetti concettuali, dalla teoria della moda alla comunicazione e, sempre in relazione agli aspetti teorici, sono stati analizzati i punti di vista della sociologia e della filosofia di questo settore. Per quanto attiene lo stato dell’arte, sono stati vagliati alcuni casi studio attinenti al progetto. Il risultato dell’elaborato è rappresentato dalla progettazione e realizzazione di un artefatto cartaceo, che non rientra nei canoni propri del catalogo o del look book. Si propone di rivisitare una selezione delle creazioni di Haute Couture dell’archivio Gattinoni sotto forma di narrazione visiva, riproposta con un linguaggio contemporaneo. Uno sguardo che dall’oggi si rivolge al passato e lo attualizza.
Development of a hyaluronic acid-based hybrid bioink for stereolithography 3D bioprinting
Creators: name: Hossain Rakin, Rafaeal
Publisher: name: University of British Columbia
Year: 2020

description: In the near future, tissue engineering and 3D bioprinting techniques will be essential to alleviate the dire need for organs for transplantation. It promises a very automated, rapidly scalable, and patient-specific process that eradicates existing concerns. Therefore, there is an immediate need to develop biomaterials with intrinsic biological functionalities that can be used to mimic In vivo conditions. Hyaluronic acid (HA), being an extra-cellular matrix derivative, promises unique prospects in tissue-specific applications by virtue of its bioactive properties. The work presented in this thesis describes a tunable protocol for the synthesis of a dual-crosslinkable methacrylated hyaluronic acid (MeHA) with a high degree of substitution to be used as a bioink for Digital Light Processing Stereolithography (DLP-SLA) 3D bioprinting. Furthermore, to overcome the non-celladhesive nature of MeHA, a hybrid bioink in combination with gelatin methacryloyl (GelMA) is developed that can be used to produce 3D cell-laden hydrogel scaffolds. Upon development of the hybrid bioink, the mechanical properties, including microarchitecture, swelling ratio, and compressive modulus, were assessed along with its biocompatibility. The results show a 55% enhancement in mechanical strength compared to its sole constituents and enable cell-attachment in the presence of MeHA while maintaining high cell viability. Preliminary investigations also reveal that the hybrid bioink is a more suitable candidate for DLP-SLA 3D bioprinting compared to MeHA because of its printability and cell-adhesive properties. Although, further optimization of the printing process with the hybrid bioink and the specific influences of MeHA on specialized cell types is required to be understood. This thesis lays out a firm foundation for the development of a stable MeHA bioink for DLA-SLA 3D bioprinting. It offers solutions to overcome its major limitations, without complex chemical modifications, by developing a hybrid hydrogel bioink.

Sheared bioconvection in a horizontal tube

description: The recent interest in using microorganisms for biofuels is motivation enough to study bioconvection and cell dispersion in tubes subject to imposed flow. To optimize light and nutrient uptake, many microorganisms swim in directions biased by environmental cues (e.g. phototaxis in algae and chemotaxis in bacteria). Such taxes inevitably lead to accumulations of cells, which, as many microorganisms have a density different to the fluid, can induce hydrodynamic instabilites. The large-scale fluid flow and spectacular patterns that arise are termed bioconvection. However, the extent to which bioconvection is affected or suppressed by an imposed fluid flow, and how bioconvection influences the mean flow profile and cell transport are open questions. This experimental study is the first to address these issues by quantifying the patterns due to suspensions of the gravitactic and gyrotactic green biflagellate alga Chlamydomonas in horizontal tubes subject to an imposed flow. With no flow, the dependence of the dominant pattern wavelength at pattern onset on cell concentration is established for three different tube diameters. For small imposed flows, the vertical plumes of cells are observed merely to bow in the direction of flow. For sufficiently high flow rates, the plumes progressively fragment into piecewise linear diagonal plumes, unexpectedly inclined at constant angles and translating at fixed speeds. The pattern wavelength generally grows with flow rate, with transitions at critical rates that depend on concentration. Even at high imposed flow rates, bioconvection is not wholly suppressed and perturbs the flow field.

The most general fourth order theory of Gravity at low energy

Publisher: name: arXiv
Year: 2010
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The Newtonian limit of the most general fourth order gravity is performed with metric approach in the Jordan frame with no gauge condition. The most general theory with fourth order differential equations is obtained by generalizing the $f(R)$ term in the action with a generic function containing other two curvature invariants: \emph{Ricci square} ($R_{αβ}R^{αβ}$) and \emph{Riemann square} ($R_{αβγδ}R^{αβγδ}$). The spherically symmetric solutions of metric tensor yet present Yukawa-like spatial behavior, but now one has two characteristic lengths. At Newtonian order any function of curvature invariants gives us the same outcome like the so-called \emph{Quadratic Lagrangian} of Gravity. From Gauss - Bonnet invariant one have the complete interpretation of solutions and the absence of a possible third characteristic length linked to Riemann square contribution. From analysis of metric potentials, generated by point-like source, one has a constraint condition on the derivatives of $f$ with respect to scalar invariants.

Sufficient conditions for thermal rectification in graded materials

description: We address a fundamental problem for the advance of phononics: the search of a feasible thermal diode. We establish sufficient conditions for the existence of thermal rectification in general graded materials. By starting from simple assumptions satisfied by the usual anharmonic models that describe heat conduction in solids, we derive an expression for the rectification. The analytical formula shows how to increase the rectification, and the conditions to avoid its decay with the system size, a problem present in the recurrent model of diodes given by the sequential coupling of two or three different parts. Moreover, for these graded systems, we show that the regimes of non-decaying rectification and of normal conductivity do not overlap. Our results indicate the graded systems as optimal materials for a thermal diode, the basic component of several devices of phononics.

description: Polarized neutron inelastic scattering has been used to measure spin excitations in ferromagnetic La$_{0.82}$Sr$_{0.18}$CoO$_{3}$. The magnon spectrum of these spin excitations is well defined at low energies but becomes heavily damped at higher energies, and can be modeled using a quadratic dispersion. We determined a spin wave stiffness constant of $D=94\pm 3$\,meV\,Å$^{2}$. Assuming a nearest-neighbor Heisenberg model we find reasonable agreement between the exchange determined from D and the bulk Curie temperature. Several possible mechanisms to account for the observed spin-wave damping are discussed.

description: This article presents a power-spectrum analysis of 39,024 measurements of the solar diameter made at the Mount Wilson Observatory from 1968.670 to 1997.965. This power spectrum contains a number of very strong peaks. We find that eight of these peaks agree closely with the frequencies of r-mode oscillations for a region of the Sun where the sidereal rotation frequency is 12.08 year$^{-1}$. We estimate that there is less than one chance in ten to the sixth power of finding this pattern by chance.

description: La matematica è noiosa, difficile, fredda, fa venire il mal di pancia e fa paura: questi sono i sentimenti che provano alcuni allievi nei confronti della matematica, soprattutto alla scuola media. I giovani nati a partire dalla fine degli anni ottanta sono definiti digital natives, ossia sono nati in un’epoca dove ormai la tecnologia è nelle case e nella quotidianità di tutti. Durante lo studio è quindi stato analizzato, mediante la somministrazione di questionari, se queste tecnologie, utilizzate per l’apprendimento della matematica possano essere di beneficio allo sviluppo delle competenze digitali, di quelle matematiche e al livello di gradimento della materia. Per questa ricerca sono state prese in analisi due classi di prima media, una che ha seguito le lezioni di matematica in un’aula dotata di computer e beamer o LIM, l’altra provvista unicamente di una lavagna tradizionale. Il risultato dello studio mostra che l’utilizzo delle ICT sembra essere di beneficio allo sviluppo delle competenze informatiche e matematiche, ma non dimostra essere di particolare utilità a livello di gradimento della materia.

description: We present new spectroscopic and photometric observations of the transiting exoplanetary system WASP-3. Spectra obtained during two separate transits exhibit the Rossiter-McLaughlin (RM) effect and allow us to estimate the sky-projected angle between the planetary orbital axis and the stellar rotation axis, lambda = 3.3^{+2.5}_{-4.4} degrees. This alignment between the axes suggests that WASP-3b has a low orbital inclination relative to the equatorial plane of its parent star. During our first night of spectroscopic measurements, we observed an unexpected redshift briefly exceeding the expected sum of the orbital and RM velocities by 140 m/s. This anomaly could represent the occultation of material erupting from the stellar photosphere, although it is more likely to be an artifact caused by moonlight scattered into the spectrograph.

description: Thermally activated flux flow (TAFF) and flux flow Hall effect (FFHE) of Fe(Te,S) single crystal in the mixed state are studied in magnetic fields up to 35 T. Thermally activated energy (TAE) is analyzed using conventional Arrhenius relation and modified TAFF theory which is closer to experimental results. The results indicate that there is a crossover from single-vortex pinning region to collective creep pinning region with increasing magnetic field. The temperature dependence of TAE is different for H//ab and H//c. On the other hand, the analysis of FFHE in the mixed state indicates that there is no Hall sign reversal. We also observe scaling behavior |Rhoxy(H)| = A*Rhoxx(H)^beta.

‘Unafraid of change’: the development of Edith Wharton’s authorship and magazines
Creators: name: Pajot, Pavlina
Publisher: name: University of British Columbia
Year: 2020

description: This dissertation, which studies Wharton’s authorship through the lens of her periodical publications and subsequent book revisions, contrary to earlier evaluations of her career, portrays her as a modern writer attuned to the changing literary marketplace and able to cater to diverse audiences. It argues that studying Wharton’s authorship—her “trajectory” (Bourdieu, Field 189)—through her engagement with various periodicals (from the higher-brow Scribner’s Magazine to the middlebrow Pictorial Review and Delineator) and within the context of the American literary field at the turn of the twentieth century offers a more nuanced view of her career as a “series of positions” in the literary arena characterized by the progressive adaptation of her authorship to the marketplace. Examining Wharton’s trajectory through her involvement with periodicals shows her as a writer who in her Scribner’s stage (1904-1913), was, to an extent, still affiliated with genteel values about art reflective of Scribner’s ideology. Then, in the 1920s and early 1930s, during her affiliation with Pictorial Review and Delineator, she became a more commercially successful and critically acclaimed professional who understood how to navigate the changing field. During the later years of the Depression when Wharton’s sales decreased and her work was often rejected by mass magazines, she became a writer out of sync with the demands of the field. In addition to examining Wharton’s changing positions, this dissertation also studies the development of her “disposition” (Bourdieu, “Habitus” 43) regarding artistic compromise—selling one’s art for money. I present a detailed discussion of the magazine versions of her artist stories published in Scribner’s, “The Descent of Man“ (1904), “The Potboiler” (1908), and “The Verdict” (1908); her Pictorial Review ghost/detective stories, “The Temperate Zone” (1924), “Miss Mary Pask” (1925), and “The Young Gentlemen” (1926); and the novels that she serialized in Delineator, namely, Hudson River Bracketed (1928-1930) and The Gods Arrive (1932). Wharton employed what I call the authorial strategy of plasticity in her postwar work, which allowed her to simultaneously cater to both the middlebrow readers of women’s magazines and her higher-brow book audience—using textual revisions, unreliable narration/perspectivism, paratext, and genre hybridity/duality/renovation.
A solid-fluid mixture model allowing for solid dilatation under external pressure

description: A sponge subjected to an increase of the outside fluid pressure expands its volume but nearly mantains its true density and thus gives way to an increase of the interstitial volume. This behaviour, not yet properly described by solid-fluid mixture theories, is studied here by using the Principle of Virtual Power with the most simple dependence of the free energy as a function of the partial apparent densities of the solid and the fluid. The model is capable of accounting for the above mentioned dilatational behaviour, but in order to isolate its essential features more clearly we compromise on the other aspects of deformation.

This paper is a sequel to one published in this journal in 2006, with similar avowed intention, by Galvez et al.. They showed only graphs, and gave no data, and no orbital elements apart from the periods (only two of which were correct) and in some cases the eccentricities. Here we provide full information and reliable orbital elements for all the stars apart from HD 160934, which has not completed a cycle since it was first observed for radial velocity.

The spots on Ap stars

description: The upper main sequence magnetic chemically peculiar (Ap) stars exhibit a non-uniform distribution of chemical elements across their surfaces and with height in their atmospheres. These inhomogeneities, responsible for the conspicuous photometric and spectroscopic variation of Ap stars, are believed to be produced by atomic diffusion operating in the stellar atmospheres stabilized by multi-kG magnetic fields. Here I present an overview of the current state-of-the-art in understanding Ap-star spots and their relation to magnetic fields. In particular, I highlight recent 3-D chemical spot structure studies and summarize magnetic field mapping results based on the inversion of the full Stokes vector spectropolarimetric observations. I also discuss a puzzling new type of spotted stars, HgMn stars, in which the formation and evolution of heavy element spots is driven by a poorly understood mechanism, apparently unrelated to magnetic fields.

title: Fc Antigen-Binding Fragment Drug Conjugates as Novel Antibody-Based Format for Targeted Drug Delivery
Creators: name: Jäger, Sebastian Michael
Publisher: name: UNSPECIFIED
Year: 2022

description: The fundamental prerequisite of therapeutic efficacy of antibody drug conjugates (ADCs) in solid tumors is the exposition of cancer cells to a therapeutically active dose of drug. One prominent strategy to maximize drug exposure, is to increase tissue penetration by smaller sized drug conjugates that extravasate faster and distribute deeper into the tumor. Fc antigen binding fragments (Fcabs) are engineered homodimeric 50 kDa Fc regions that incorporate all essential immunoglobulin G (IgG) functionalities such as neonatal Fc receptor (FcRn)-mediated recycling and antigen binding at only one-third of the size. The combination of reduced size and favorable pharmacokinetics makes Fcabs an attractive alternative to the conventional IgG scaffold employed in ADCs, with potentially improved tissue penetration capabilities. In the present study, Fcabs were explored for the first time as a novel scaffold for ADCs. For proof-of-principle, HER2- and EGFR-targeting Fcabs were selected, coupled to a pH sensitive dye, and subsequently tested for receptor-mediated endocytosis on tumor cells. Target-dependent cellular binding and uptake confirmed the suitability of the selected Fcabs for targeted intracellular drug delivery. Moreover, Fcabs were conjugated to cytotoxic monomethyl auristatin E (MMAE) employing site-specific enzymatic or cysteine coupling. The feasibility of Fcab-drug conjugates could be demonstrated by retained binding to target receptor and half-life prolonging FcRn, conjugation site dependent serum stability and target-mediated cell killing at sub-nanomolar to double digit nanomolar concentrations. Moreover, HER2-targeting Fcab-dye constructs were tested in a tumor cell spheroid model and showed elevated penetration compared to a 150 kDa Fcab derivative with unrelated Fab arms or to the clinically validated HER2-targeting antibody Trastuzumab. Overall, this study demonstrates the applicability of the Fcab format as targeting scaffold for the generation of drug conjugates and emphasizes the potential of Fcab drug conjugates for improved tumor penetration in solid cancers.
Boundary crisis and suppression of Fermi acceleration in a dissipative two dimensional non-integrable time-dependent billiard

description: Some dynamical properties for a dissipative time-dependent oval-shaped billiard are studied. The system is described in terms of a four-dimensional nonlinear mapping. Dissipation is introduced via inelastic collisions of the particle with the boundary, thus implying that the particle has a fractional loss of energy upon collision. The dissipation causes profound modifications in the dynamics of the particle as well as in the phase space of the non dissipative system. In particular, inelastic collisions can be assumed as an efficient mechanism to suppress Fermi acceleration of the particle. The dissipation also creates attractors in the system, including chaotic. We show that a slightly modification of the intensity of the damping coefficient yields a drastic and sudden destruction of the chaotic attractor, thus leading the system to experience a boundary crisis. We have characterized such a boundary crisis via a collision of the chaotic attractor with its own basin of attraction and confirmed that inelastic collisions do indeed suppress Fermi acceleration in two-dimensional time dependent billiards.

Applications of Little's Law to stochastic models of gene expression

description: The intrinsic stochasticity of gene expression can lead to large variations in protein levels across a population of cells. To explain this variability, different sources of mRNA fluctuations ('Poisson' and 'Telegraph' processes) have been proposed in stochastic models of gene expression. Both Poisson and Telegraph scenario models explain experimental observations of noise in protein levels in terms of 'bursts' of protein expression. Correspondingly, there is considerable interest in establishing relations between burst and steady-state protein distributions for general stochastic models of gene expression. In this work, we address this issue by considering a mapping between stochastic models of gene expression and problems of interest in queueing theory. By applying a general theorem from queueing theory, Little's Law, we derive exact relations which connect burst and steady-state distribution means for models with arbitrary waiting-time distributions for arrival and degradation of mRNAs and proteins. The derived relations have implications for approaches to quantify the degree of transcriptional bursting and hence to discriminate between different sources of intrinsic noise in gene expression. To illustrate this, we consider a model for regulation of protein expression bursts by small RNAs. For a broad range of parameters, we derive analytical expressions (validated by stochastic simulations) for the mean protein levels as the levels of regulatory small RNAs are varied. The results obtained show that the degree of transcriptional bursting can, in principle, be determined from changes in mean steady-state protein levels for general stochastic models of gene expression.

description: We have found a remarkably large response of the transition temperature of CaFe2As2 single crystals grown out of excess FeAs to annealing / quenching temperature. Whereas crystals that are annealed at 400 C exhibit a first order phase transition from a high temperature tetragonal to a low temperature orthorhombic and antiferromagnetic state near 170 K, crystals that have been quenched from 960 C exhibit a transition from a high temperature tetragonal phase to a low temperature, non-magnetic, collapsed tetragonal phase below 100 K. By use of temperature dependent electrical resistivity, magnetic susceptibility, X-ray diffraction, Mossbauer spectroscopy and nuclear magnetic resonance measurements we have been able to demonstrate that the transition temperature can be reduced in a monotonic fashion by varying the annealing / quenching temperature from 400 to 850 C with the low temperature state remaining antiferromagnetic for transition temperatures larger than 100 K and becoming collapsed tetragonal / non-magnetic for transition temperatures below 90 K. This suppression of the orthorhombic / antiferromagnetic phase transition and its ultimate replacement with the collapsed tetragonal / non-magnetic phase is similar to what has been observed for CaFe2As2 under hydrostatic pressure. Transmission electron microscopy studies indicate that there is a temperature dependent, width of formation of CaFe2As2 with a decreasing amount of excess Fe and As being soluble in the single crystal at lower annealing temperatures. For samples quenched from 960 C there is a fine (of order 10 nm), semi-uniform distribution of precipitate that can be associated with an average strain field whereas for samples annealed at 400 C the excess Fe and As form mesoscopic grains that induce little strain throughout the CaFe2As2 lattice.
