description: Skyrmions are nanoscale magnetic structures with features promising for future low-power memory or logic devices. In this work, we demonstrate novel scanning techniques based on nitrogen vacancy center magnetometry that simultaneously probe both the magnetic dynamics and structure of room temperature skyrmion bubbles in a thin film system Ta/CoFeB/MgO. We confirm the handedness of the Dzyaloshinskii-Moriya interaction in this material and extract the helicity angle of the skyrmion bubbles. Our measurements also show that the skyrmion bubbles in this material change size in discrete steps, dependent on the local pinning environment, with their average size determined dynamically as their domain walls hop between pinning sites. In addition, an increase in magnetic field noise is observed near all skyrmion bubble domain walls. These measurements highlight the importance of interactions between internal degrees of freedom of skyrmion bubble domain walls and pinning sites in thin film systems. Our observations have relevance for future devices based on skyrmion bubbles where pinning interactions will determine important aspects of current-driven motion.

description: In this paper, we find criteria for when cyclic cubic and cyclic quartic fields have well-rounded ideal lattices. We show that every cyclic cubic field has at least one well-rounded ideal. We also prove that there exist families of cyclic quartic fields which have well-rounded ideals and explicitly construct their minimal bases. In addition, for a given prime number $p$, if a cyclic quartic field has a unique prime ideal above $p$, then we provide the necessary and sufficient conditions for that ideal to be well-rounded. Moreover, in cyclic quartic fields, we provide the prime decomposition of all odd prime numbers and construct an explicit integral basis for every prime ideal.

Publisher: name: The University of British Columbia
Year: 2016

description: This session was about libraries and archives embracing open source software for digital preservation as demonstrated by large institutions such as MIT, Harvard, and The National Archives of the UK, to name a few. These organizations have developed and distributed open source tools for digital preservation ranging from format identification tools to repository software. The development of open source records management software by contrast has been slow to develop. This presentation discussed the reasons for this dichotomy through a discussion of the ongoing work of the InterPARES 3 general study – Open Source Records Management Software and reports on an early evaluation of the first open source records management software. This session took place on October 19, 2010 in the Lillooet Room of the Irving K. Barber Learning Centre at the University of British Columbia.

description: Traditional stabilizer codes operate over prime power local-dimensions. In this work we extend the stabilizer formalism using the local-dimension-invariant setting to import stabilizer codes from these standard local-dimensions to other cases. In particular, we show that any traditional stabilizer code can be used for analog continuous-variable codes, and consider restrictions in phase space and discretized phase space. This puts this framework on an equivalent footing as traditional stabilizer codes. Following this, using extensions of prior ideas, we show that a stabilizer code originally designed with a finite field local-dimension can be transformed into a code with the same $n$, $k$, and $d$ parameters for any integral domain. This is of theoretical interest and can be of use for systems whose local-dimension is better described by mathematical rings, which permits the use of traditional stabilizer codes for protecting their information as well.

Investigating exosomes for regenerative medicine: development of purification techniques and novel analytical strategies for assessment of potency
Creators: name: Whittaker, Thomas Edmund
Publisher: name: Imperial College London
Year: 2018

description: No living cell has yet been reported that does not release extracellular vesicles (EVs). The last decade has seen an explosion of research into their properties as biomarkers, drug carriers, effectors of signalling and potential therapeutics. Within the field of regenerative medicine, EVs have recently been implicated in the therapeutic paracrine signalling of human mesenchymal stem cells (hMSCs) after transplantation. They appear to represent a promising cell-free therapy for myocardial infarction, stroke, and other diseases. However, effective purification of EVs without accompanying contamination from other cell-derived factors is challenging. There is debate within the field as to the fitness for purpose of several commonly-used isolation techniques. Cell signalling via EVs is not typically directly compared to signalling via conventional soluble factors, and there are no widely-adopted standards for assessing potency. Here, an effective EV isolation system was developed and validated to be capable of fully separating EVs from free protein. HMSC-EVs isolated with this system were found to be ineffective stimulants of in vitro assays of angiogenesis and wound healing. It was found that hMSC-EVs could only stimulate these assays when purified by a low-stringency technique or when used at very high concentrations. Ultrafiltration experiments similar to those that initially suggested the necessity of EVs in hMSC signalling were found to be prone to false positives. When evaluated in experiments that allowed direct quantitative comparison with non-EV factors produced by the same cells, non-EV factors were repeatedly found to be necessary and sufficient for hMSC paracrine stimulation of in vitro angiogenesis and wound healing. A conceptual framework for quantitative evaluation of the contribution of EVs to signalling processes is proposed.
On the nature of a secondary main sequence turn-off in the rich LMC cluster NGC 1868

description: Evidence for a second main-sequence turn-off in a deep colour-magnitude diagram of NGC 1868 is presented. The data were obtained with HST/WFPC2 and reach down to m_{555} ~ 25. Besides the usual t ~ 0.8 Gyr turn-off found in previous analyses, another possible turn-off is seen at m_{555} ~ 21 (M_V ~ 2.5), which is consistent with an age of t ~ 3 Gyrs. This CMD feature stands out clearly especially when contaminating field LMC stars are statistically removed. The background subtracted CMD also visibly displays a red subgiant branch extending about 1.5 mag below the younger turn-off and the clump of red giants. The significance of the secondary turn-off in NGC 1868 was confirmed with Monte-Carlo simulations and bootstrapping techniques. Star-counts in selected regions in the cluster CMD indicate a mass ratio of old population/young population in the range 5% <= M_{old} / M_{young} <= 12%, depending on the mass function slope. The existence of such a subpopulation in NGC 1868 is significant even in the presence of uncertainties in background subtraction. The possibility that the secondary turn-off is associated with the field star population was examined by searching for similar features in CMDs of field stars. Statistically significant excesses of stars redwards of the main-sequence were found in all such fields in the range 20 <= m_{555} <= 22. These however are much broader features that do not resemble the main-sequence termination of a single population. We also discuss other alternative explanations for the feature at m_{555} ~ 21, such as unresolved binarism, peculiar stars or CMD discontinuities associated with the Bohm-Vitense gap.

description: There are no o¢ cial quarterly real GDP estimates for New Zealand, for the period prior to 1977. We develop a seasonally adjusted series for 1947q2 to 2006q2, by linking quarterly observations from two recent ofÖcial series to temporally disaggregated observations for an earlier time period. Annual real GDP series are disaggregated, using the information from two quarterly di§usion indexes, developed by Haywood and Campbell (1976). Three econometric models are used: the Chow and Lin (1971) model that disaggregates the level of GDP; and the Fern·ndez (1981) and Litterman (1983) models that disaggregate changes in GDP. Statistical properties of the series are evaluated, and movements in the new series are benchmarked against qualitative research Öndings from New Zealandís post-WWII economic history. Our preferred quarterly series is based on results generated from the Chow-Lin model.

Impact Of Generic Fluid Milk And Cheese Advertising On Dairy Markets 1984-99

Publisher: name: Unknown
Year: 2000
Subjects: Livestock Production/Industries

description: The purpose of this study was to analyze the impacts of generic milk and cheese advertising on dairy markets. The results indicated that generic milk and cheese advertising by dairy farmers and fluid milk processors had major market impacts for the dairy industry. The main conclusion of the study is that farmers and processors are receiving a high return on their investment in generic dairy advertising. The impacts of advertising tend to be more profound in increasing price than quantity, which is due to the inelastic nature of demand for milk and cheese. These estimated impacts need to be compared with the other options producers and processors have for marketing their product (e.g., non-advertising promotion, research, new product development, etc.) in order to determine the optimality of the current investment of advertising. Consequently, these results should be viewed as a first step in the evaluation process.

description: Brans-Dicke gravity is remarkable not only in that General Relativity and Mach's Principle find a common enlarged scenario where they are mutually consistent, but also in that it provides a very interesting quantum cosmological model within the inflationary paradigm. The interplay between the Brans-Dicke scalar $Φ$ and the inflaton field $σ$ plays an important rôle during the course of inflation, and although the dynamics as such is governed by the potential, the onset and the end of inflation are determined by the values of both fields jointly. The relative position of the beginning-- and end-of-inflation curves (BoI and EoI respectively) is the most relevant factor in determining the resulting quantum cosmological scenario. The classification of potentials that is given in this paper is based on the criterion of whether the BoI and EoI boundaries enclose a finite or infinite area in the ($σ$,$Φ$) plane where inflation takes place. It is shown that this qualitative classification distinguishes two classes of potentials that yield very different cosmologies and it is argued that only those theories in which BoI and EoI enclose a finite area in the ($σ$,$Φ$) plane are compatible with our observable universe.

description: A new approach to nonlinear modelling is presented which, by incorporating the global behaviour of the model, lifts shortcomings of both least squares and total least squares parameter estimates. Although ubiquitous in practice, a least squares approach is fundamentally flawed in that it assumes independent, normally distributed (IND) forecast errors: nonlinear models will not yield IND errors even if the noise is IND. A new cost function is obtained via the maximum likelihood principle; superior results are illustrated both for small data sets and infinitely long data streams.

description: In this paper we give a first study of perfect copositive $n \times n$ matrices. They can be used to find rational certificates for completely positive matrices. We describe similarities and differences to classical perfect, positive definite matrices. Most of the differences occur only for $n \geq 3$, where we find for instance lower rank and indefinite perfect matrices. Nevertheless, we find for all $n$ that for every classical perfect matrix there is an arithmetically equivalent one which is also perfect copositive. Furthermore we study the neighborhood graph and polyhedral structure of perfect copositive matrices. As an application we obtain a new characterization of the cone of completely positive matrices: It is equal to the set of nonnegative matrices having a nonnegative inner product with all perfect copositive matrices.

Additionally, we discuss an application of successive minima to a version of Siegel's lemma.

description: The paper develops the fundamentals of quaternionic holomorphic curve theory. The holomorphic functions in this theory are conformal maps from a Riemann surface into the 4-sphere, i.e., the quaternionic projective line. Basic results such as the Riemann-Roch Theorem for quaternionic holomorphic vector bundles, the Kodaira embedding and the Pluecker relations for linear systems are proven. Interpretations of these results in terms of the differential geometry of surfaces in 3- and 4-space are hinted at throughout the paper. Applications to estimates of the Willmore functional on constant mean curvature tori, respectively energy estimates of harmonic 2-tori, and to Dirac eigenvalue estimates on Riemannian spin bundles in dimension 2 are given.

Non-melanoma skin cancer in HIV infection: the role of human papillomavirus (HPV), individual immunogenotype (HLA ‘tissue type’) and Merkel cell polyomavirus (MCV)
Creators: name: Goolamali, Sacha Imran
Publisher: name: Imperial College London
Year: 2020

description: Non-melanoma skin cancer (NMSC) in HIV presents increasing problems e.g. incidence and morbidity. Ultraviolet light and human papillomavirus (HPV) are implicated in NMSC pathogenesis. In HIV, HPV is unequivocally involved in oral, anogenital and cervical squamous cell cancer (SCC) but its role in cutaneous SCC is unclear. Merkel cell polyomavirus (MCV), the cause of Merkel cell carcinoma, has not been investigated in NMSC in HIV. HLA immunogenotype characterises some dermatoses in HIV and associations with NMSC have been reported in organ transplant recipients, but its role in HIV NMSC is unknown. HIV+ve cases and HIV–ve controls (each n=58) with NMSC and NM pre-cancer were identified. DNA was extracted from tissue (n=113, n=123 samples respectively) for broad-spectrum HPV/MCV typing and blood (n=107) for HLA typing by specific and sensitive PCR-based methodologies. HIV samples showed higher overall HPV prevalence (51%/41% HIV-ve). Genital types were more prevalent (47%/44%) than beta (36%/36%) or wart types (17%/20%). High risk (HR) types (69%/60%; 74%/77% from non-genital skin) and multiple types were more prevalent (19%/14%), but only the differences between genital and wart types were statistically significant (Yates: p<0.05). Of all NMSC/pre-cancer samples, 23% were MCV+ve; 39% HIV+ve; 36% MCV+ve were HPV co-infected (no difference between groups). Several HLA associations were found; one, HLA-DQA1*01 (controls) was significant (Bonferroni: p<0.05). HPV is prevalent in HIV+ve/HIV-ve NMSC/pre-cancer supporting a carcinogenic role. Although isolated mainly from extragenital skin, genital types were the most common in both groups; beta types previously reported as commonest in NMSC. HR types seemed more prevalent in HIV. Overall HPV prevalence and HR and multiple types seem more prevalent in HIV NMSC/precancer (although not statistically significant), possibly reflecting immune status differences. MCV, is prevalent in NMSC/pre-cancer, regardless of HIV or HPV; its part in carcinogenesis remains unclear. HLA immunogenotype may play a role in NMSC pathogenesis.

description: Multi-frequency observations of Mrk 348 are presented consisting of 2 epochs of MERLIN data at 5 GHz, ISOPHOT data at 170, 90, 60 and 25 micron, NOT images at U, B, R and I bands and data at 1350 micron from the archive for SCUBA. The new optical images reveal a disrupted arm that ends towards the eastern companion of Mrk 348, consistent with the hypothesis that Mrk 348 and its companion form an interacting system. 5 GHz MERLIN imaging shows that only one of the radio components of Mrk 348 is polarized (%P=5). The broadband spectrum of Mrk 348 is flat between the radio and millimetre bands, suggesting that synchrotron emission extends to high frequencies. Mrk 348 has many of the characteristics of a radio-loud object. We discuss the orientation of the radio axis of Mrk 348 with respect to the line of sight. We conclude that the evidence is conflicting, and the geometry in Mrk 348 is not well-described by a simple edge-on or face-on model.

description: Excerpts from the report Introduction: Sale of nonfat dry milk in retail packages is a relatively recent innovation in dairy marketing. Although nonfat dry milk was available to civilian consumers in the early years of World War II, and was widely used by the armed forces and by civilian populations abroad, it was not until well after the war's end that quality and ease of reconstitution were such that the product was generally acceptable to the American housewife. Since 1948 sales of nonfat dry milk for home use have spiraled upward. From a little over 2 million pounds in 1948, sales rose to 30 million pounds in 1950, and to an estimated 169 million pounds in 1958. Despite rapid growth, sales of nonfat dry milk for home use accounted for only about one-fifth of total domestic nongovernment sales of nonfat dry milk for food use in 1958. Sales for home use in 1958 were at the rate of less than 1 pound per capita out of a total use per capita of over 5 pounds, low in comparison with that for some other dairy products—12.6 pounds of evaporated milk per capita, 8.5 pounds of butter, and 17.6 pounds of ice cream, for example. The purpose of this report, therefore, is to provide information concerning nonfat dry milk produced for home use: The cost of manufacture, the agencies involved in marketing the product, the functions they perform and the marketing practices they follow, the cost of their services, and the farm-to-retail price spread or marketing margin.

description: The magnetic properties of (Ca,Sr)RuO_3 and Sr_2YRuO_6 are studied within the context of band structure based Stoner theory. LSDA calculations without recourse to strong correlation effects yield the correct magnetic behavior and order in all cases. Insulating character of Sr_2YRuO_6 is reproduced. The different magnetic states of SrRuO_3 and CaRuO_3 are shown to be due to the different structural distortions. CaRuO_3 is found to be on the verge of a ferromagnetic instability. O p states hybridize strongly with Ru d states in all three compounds, and O, through this hybridization plays an unusually large role in the magnetic properties. Transport properties of CaRuO_3 and SrRuO_3 are analyzed using the calculated Fermiology. Unusually large magnon and paramagnon couplings are found, which are consistent with reported measurements of the low temperature specific heat and the resistivity coefficient. We also demonstrate how the calculated band structures can be understood in terms of a nearest neighbor tight binding model.

The case of the special linear Lie algebra $\mathfrak{sl}(n,{\mathbb C})$ is emphasized.

description: Modern programming frequently requires generalised notions of program equivalence based on a metric or a similar structure. Previous work addressed this challenge by introducing the notion of a V-equation, i.e. an equation labelled by an element of a quantale V, which covers inter alia (ultra-)metric, classical, and fuzzy (in)equations. It also introduced a V-equational system for the linear variant of lambda-calculus where any given resource must be used exactly once.
 In this paper we drop the (often too strict) linearity constraint by adding graded modal types which allow multiple uses of a resource in a controlled manner. We show that such a control, whilst providing more expressivity to the programmer, also interacts more richly with V-equations than the linear or Cartesian cases. Our main result is the introduction of a sound and complete V-equational system for a lambda-calculus with graded modal types interpreted by what we call a Lipschitz exponential comonad. We also show how to build such comonads canonically via a universal construction, and use our results to derive graded metric equational systems (and corresponding models) for programs with timed and probabilistic behaviour.

description: Motivated by diverse phenomena in cellular biophysics, including bacterial flagellar motion and DNA transcription and replication, we study the overdamped nonlinear dynamics of a rotationally forced filament with twist and bend elasticity. Competition between twist injection, twist diffusion, and writhing instabilities is described by a novel pair of coupled PDEs for twist and bend evolution. Analytical and numerical methods elucidate the twist/bend coupling and reveal two dynamical regimes separated by a Hopf bifurcation: (i) diffusion-dominated axial rotation, or twirling, and (ii) steady-state crankshafting motion, or whirling. The consequences of these phenomena for self-propulsion are investigated, and experimental tests proposed.

Here we give an alternative simple proof of this fact and construct explicitly the vanishing cycles of the Lefschetz fibration, obtaining a direct identification of the set of compact Stein manifolds with positive allowable Lefschetz fibrations over a 2-disk. In the process we associate to every compact Stein manifold infinitely many nonequivalent such Lefschetz fibrations.

description: Nonintegrable systems thermalize, leading to the emergence of fluctuating hydrodynamics. Typically, this hydrodynamics is diffusive. We use the effective field theory (EFT) of diffusion to compute higher-point functions of conserved densities. We uncover a simple scaling behavior of correlators at late times, and, focusing on three and four-point functions, derive the asymptotically exact universal scaling functions that characterize nonlinear response in diffusive systems. This allows for precision tests of thermalization beyond linear response in quantum and classical many-body systems. We confirm our predictions in a classical lattice gas.

Direct Mott Insulator-to-Superfluid Transition in the Presence of Disorder

description: We introduce a new renormalization group theory to examine the quantum phase transitions upon exiting the insulating phase of a disordered, strongly interacting boson system. For weak disorder we find a direct transition from this Mott insulator to the Superfluid phase. In d > 4 a finite region around the particle-hole symmetric point supports this direct transition, whereas for 2=< d <4 perturbative arguments suggest that the direct transition survives only precisely at commensurate filling. For strong disorder the renormalization trajectories pass next to two fixed points, describing a pair of distinct transitions; first from the Mott insulator to the Bose glass, and then from the Bose glass to the Superfluid. The latter fixed point possesses statistical particle-hole symmetry and a dynamical exponent z, equal to the dimension d.

description: We study the phase synchronization (PS) with type-II intermittency showing $\pm 2 π$ irregular phase jumping behavior before the PS transition occurs in a system of two coupled hyperchaotic Rössler oscillators. The behavior is understood as a stochastic hopping of an overdamped particle in a potential which has $2 π$-periodic minima. We characterize it as type-II intermittency with external noise through the return map analysis. In $ε_{t} < ε< ε_{c}$ (where $ε_{t}$ is the bifurcation point of type-II intermittency and $ε_{c}$ is the PS transition point in coupling strength parameter space), the average length of the time interval between two successive jumps follows $ \sim \exp(\midε_{t} - ε\mid^{2})$, which agrees well with the scaling law obtained from the Fokker-Planck equation.

description: In this paper, we systematically study the measures of multi-partite entanglement with the aim of constructing those measures that can be computed in probe approximation in the holographic dual. We classify and count general measures as invariants of local unitary transformations. After formulating these measures in terms of permutation group elements, we derive conditions that a probe measure should satisfy and find a large class of solutions. These solutions are generalizations of the multi-entropy introduced in arXiv:2206.09723 . We derive their holographic dual with the assumption that the replica symmetry is unbroken in the bulk and check our prescription with explicit computations in $2d$ CFTs. Analogous to the multi-entropy, the holographic dual of these measures is given by the weighted area of the minimal brane-web but with branes having differing tensions. We discuss the replica symmetry assumption and also how the already known entanglement measures, such as entanglement negativity and reflected entropy fit in our framework.

description: A distance mean function measures the average distance of points from the elements of a given set of points (focal set) in the space. The level sets of a distance mean function are called generalized conics. In case of infinite focal points the average distance is typically given by integration over the focal set. The paper contains a survey on the applications of taxicab distance mean functions and generalized conics' theory in geometric tomography: bisection of the focal set and reconstruction problems by coordinate X-rays. The theoretical results are illustrated by implementations in Maple, methods and examples as well.

The integer point transform as a complete invariant

description: The integer point transform $σ_{\mathcal P}$ is an important invariant of a rational polytope $\mathcal P$, and here we show that it is a complete invariant. We prove that it is only necessary to evaluate $σ_{\mathcal P}$ at one algebraic point in order to uniquely determine $\mathcal P$, by employing the Lindemann-Weierstrass theorem. Similarly, we prove that it is only necessary to evaluate the Fourier transform of a rational polytope $\mathcal P$ at a single algebraic point, in order to uniquely determine $\mathcal P$. We prove that identical uniqueness results also hold for integer cones.
 In addition, by relating the integer point transform to finite Fourier transforms, we show that a finite number of \emph{integer point evaluations} of $σ_{\mathcal P}$ suffice in order to uniquely determine $\mathcal P$. We also give an equivalent condition for central symmetry of a finite point set, in terms of the integer point transform, and prove some facts about its local maxima. Most of the results are proven for arbitrary finite sets of integer points in $\mathbb R^d$.

description: We develop a new method to calculate finite size corrections for form factors in two-dimensional integrable quantum field theories. We extract these corrections from the excited state expectation value of bilocal operators in the limit when the operators are far apart. We elaborate the finite size effects explicitly up to the 3rd Lüscher order and conjecture the structure of the general form. We also fully recover the explicitly known massive fermion finite volume form factors.
description: 39 pages, 9 figures. In this corrected manuscript, we clarified the text at multiple points and added a separate section (5) containing the definition of the connected form factors and a derivation of the graph rules for their evaluation. We also added a short section (6) about how our calculation can be extended from a one-particle state to multiparticle states

description: Global hydrological and land surface models are increasingly used for tracking terrestrial total water storage (TWS) dynamics, but the utility of existing models is hampered by conceptual and/or data uncertainties related to various underrepresented and unrepresented processes, such as groundwater storage. The gravity recovery and climate experiment (GRACE) satellite mission provided a valuable independent data source for tracking TWS at regional and continental scales. Strong interests exist in fusing GRACE data into global hydrological models to improve their predictive performance. Here we develop and apply deep convolutional neural network (CNN) models to learn the spatiotemporal patterns of mismatch between TWS anomalies (TWSA) derived from GRACE and those simulated by NOAH, a widely used land surface model. Once trained, our CNN models can be used to correct the NOAH simulated TWSA without requiring GRACE data, potentially filling the data gap between GRACE and its follow-on mission, GRACE-FO. Our methodology is demonstrated over India, which has experienced significant groundwater depletion in recent decades that is nevertheless not being captured by the NOAH model. Results show that the CNN models significantly improve the match with GRACE TWSA, achieving a country-average correlation coefficient of 0.94 and Nash-Sutcliff efficient of 0.87, or 14\% and 52\% improvement respectively over the original NOAH TWSA. At the local scale, the learned mismatch pattern correlates well with the observed in situ groundwater storage anomaly data for most parts of India, suggesting that deep learning models effectively compensate for the missing groundwater component in NOAH for this study region.

Étude exploratoire de l'échec entrepreneurial des femmes en Côte d'Ivoire
Creators: name: KOBRI, Macoura Madina
Publisher: name: Zenodo
Year: 2025
Subjects: Échec ; Entrepreneuriat ; Femmes ; Processus.

description: La plupart des travaux académiques et scientifiques appréhendent le concept d’échec entrepreneurial à partir de critères et d’éléments dualistes les opposant parfois les uns par rapport aux autres. Ces approches dans lesquelles s’inscrivent nombre des chercheurs restent focalisées uniquement sur les critères de mesures classiques (objectifs et subjectifs) renforçant ainsi les controverses et les arguments sexistes sur la comparaison homme-femme. En accord avec Carrier et al. (2006) qui proposent d’aller au-delà des approches connues, pour montrer la manière dont des facteurs culturels peuvent permettre une compréhension fine des concepts, cette étude se propose d’investiguer les femmes entrepreneures en Côte d’Ivoire (contexte culturellement fort). Adoptant une démarche interprétative basée sur des observations participantes et des récits de vie dans trois régions du pays, nous montrons que l’échec des femmes entrepreneures suit une logique processuelle qui prend forme dans l’interaction entre l’entrepreneure et les acteurs de son milieu socioculturel.
