description: In neural audio signal processing, pitch conditioning has been used to enhance the performance of synthesizers. However, jointly training pitch estimators and synthesizers is a challenge when using standard audio-to-audio reconstruction loss, leading to reliance on external pitch trackers. To address this issue, we propose using a spectral loss function inspired by optimal transportation theory that minimizes the displacement of spectral energy. We validate this approach through an unsupervised autoencoding task that fits a harmonic template to harmonic signals. We jointly estimate the fundamental frequency and amplitudes of harmonics using a lightweight encoder and reconstruct the signals using a differentiable harmonic synthesizer. The proposed approach offers a promising direction for improving unsupervised parameter estimation in neural audio applications.

description: Session-based recommendation (SR) aims to dynamically recommend items to a user based on a sequence of the most recent user-item interactions. Most existing studies on SR adopt advanced deep learning methods. However, the majority only consider a special behavior type (e.g., click), while those few considering multi-typed behaviors ignore to take full advantage of the relationships between products (items). In this case, the paper proposes a novel approach, called Substitutable and Complementary Relationships from Multi-behavior Data (denoted as SCRM) to better explore the relationships between products for effective recommendation. Specifically, we firstly construct substitutable and complementary graphs based on a user's sequential behaviors in every session by jointly considering `click' and `purchase' behaviors. We then design a denoising network to remove false relationships, and further consider constraints on the two relationships via a particularly designed loss function. Extensive experiments on two e-commerce datasets demonstrate the superiority of our model over state-of-the-art methods, and the effectiveness of every component in SCRM.

description: Ando, Matsuzawa, Thom, and Törnquist have resolved a problem by Sorin Popa by constructing an example of a Polish group of unitary operators with the strong operator topology, whose left and right uniform structures coincide, but which does not embed into the unitary group of a finite von Neumann algebra. The question remained whether such a group can be connected. Here we observe that a connected (in fact, homeomorphic to the Hilbert space) example is obtained from the example of the above authors via the Hartman--Mycielski construction.

description: Kein anderes Lebensmittel ist in Tages- und Wochenzeitungen so präsent wie Milch. Nach dem Ende der Milchquote im Jahr 2015 scheint sich die Berichterstattung jedoch verändert zu haben: Sie wird immer wieder als einseitig krisenorientiert kritisiert. Ob und wie sich die Berichterstattung verändert hat, wird im nachfolgenden Beitrag mit Hilfe einer Inhaltsanalyse sowie einer darauf aufbauenden Regressionsanalyse untersucht. Das zentrale Ergebnis ist, dass über Milchpreise insbesondere in Zeiten niedriger und stark fallender Preise berichtet wird. Ein weiteres Ergebnis ist, dass sich das Quotenende positiv auf die Anzahl der veröffentlichten Artikel auswirkt. Eine verstärkt einseitige Berichterstattung, beispielsweise zunehmend negative Kritik an den Milcherzeugern, kann jedoch nicht festgestellt werden.

description: Systems driven by multiple physical processes are central to many areas of science and engineering. Time discretization of multiphysics systems is challenging, since different processes have different levels of stiffness and characteristic time scales. The multimethod approach discretizes each physical process with an appropriate numerical method; the methods are coupled appropriately such that the overall solution has the desired accuracy and stability properties. The authors developed the general-structure additive Runge-Kutta (GARK) framework, which constructs multimethods based on Runge-Kutta schemes. This paper constructs the new GARK-ROS/GARK-ROW families of multimethods based on linearly implicit Rosenbrock/Rosenbrock-W schemes. For ordinary differential equation models, we develop a general order condition theory for linearly implicit methods with any number of partitions, using exact or approximate Jacobians. We generalize the order condition theory to two-way partitioned index-1 differential-algebraic equations. Applications of the framework include decoupled linearly implicit, linearly implicit/explicit, and linearly implicit/implicit methods. Practical GARK-ROS and GARK-ROW schemes of order up to four are constructed.

Tierwohl und die ethische Bewertung der Tierhaltung rücken dabei immer stärker in den Fokus der Öffentlichkeit. Dabei liegen die Positionen von Verbrauchern, Tierschützern, Journalisten und Landwirten meist weit auseinander. Mit dem Projekt „SocialLab – Nutztierhaltung im Spiegel der Gesellschaft“ soll die Kluft zwischen den Akteuren ergründet und reduziert werden.

description: Uganda has been challenged to translate recovery-based economic buoyancy into sustainable growth with poverty reduction in pursuit of national and international development targets. As the country weighs various options for stimulating an appropriate response to the economic slowdown of the recent years, it is important that policy considerations be informed by a review of the difference growth strategies and episodes that the country experienced. This paper therefore, provided an overview of the broad economic strategies that have been implemented in Uganda since 1962 when it attained Independence. By focusing on what transpired during the 1990s into the 2000s, the paper aims to assess the extent to which recent development strategies promoted the participation of poor people in Uganda's growth process. Furthermore, the paper highlights the tradeoffs associated with policies that emphasize growth versus those that emphasize distribution in pursuit of poverty reduction.

description: Using the 2002/03 Uganda National Household Survey data we empirically examine the nature and determinants of individuals' decision to seek care on condition of illness reporting. The major findings include: cost of care is regressive and sustainability reduces the health care utilization for any formal provider by the poorer individuals afters controlling for other factors. In other words, even among public facilities cost of care remains a barrier to utilization of these services. Second, there is no doubt that putting in place strategies aimed at increasing the income of the poor will increase their utilization of the health facilities, though the impact will be higher for private care. Third, besides income and cost and cost of care, other factors in particular qualify of services, education and physical access proxied by distance to the facilities are important determinants of health care utilization. Four, as much as it is important for the government to improve provision of services in the public facilities, incentives should be put in place to encourage and strengthen the role of the private sector. At the same time there is need, to put in place a regulatory system, set standards and a monitoring framework to ensure quality of services and control prices in the private sector especially in the private for profit sub-sector. Clearly there is an increasing preference for the sector's services even after the abolition of cost sharing.
Spintronics meets nonadiabatic molecular dynamics: Geometric spin torque and damping on noncollinear classical magnetism due to electronic open quantum system

description: We analyze a quantum-classical hybrid system of steadily precessing slow classical localized magnetic moments, forming a head-to-head domain wall, embedded into an open quantum system of fast nonequilibrium electrons. The electrons reside within a metallic wire connected to macroscopic reservoirs. The model captures the essence of dynamical noncollinear and noncoplanar magnetic textures in spintronics, while making it possible to obtain the exact time-dependent nonequilibrium density matrix of electronic system and split it into four contributions. The Fermi surface contribution generates dissipative (or damping-like in spintronics terminology) spin torque on the moments, and one of the two Fermi sea contributions generates geometric torque dominating in the adiabatic regime. When the coupling to the reservoirs is reduced, the geometric torque is the only nonzero contribution. Locally it has both nondissipative (or field-like in spintronics terminology) and damping-like components, but with the sum of latter being zero, which act as the counterparts of geometric magnetism force and electronic friction in nonadiabatic molecular dynamics. Such current-independent geometric torque is absent from widely used micromagnetics or atomistic spin dynamics modeling of magnetization dynamics based on the Landau-Lifshitz-Gilbert equation, where previous analysis of Fermi surface-type torque has severely underestimated its magnitude.

description: Diese Arbeit versucht die sogenannte Konvergenzhypothese mit einem Ansatz von Phillips und Sul (2007 und 2009) empirisch zu überprüfen. Der Ausgangspunkt ist ein neoklassische Wachstumsmodell, genauer gesagt ein erweitertes Solow Modell. Nach theoretischen Vorarbeiten führt der Weg zu einem nichtlinearen Faktormodell, welches zur Beschreibung des logarithmierten pro Kopf Einkommen herangezogen wird. Ein gemeinsamer Faktor beschreibt die gemeinsame Entwicklung aller Länder im jeweiligen Panel, wohingegen eine idiosynkratische Komponente den jeweiligen Anteil eines Individuums am gemeinsamen Pfad misst. Da dieser individuenspezifische Faktor schwer zu schätzen ist, basiert die grafische und quantitative Analyse auf relativen Übergangspfaden. Phillips und Sul konstruieren einen statistischen Test zur Überprüfung der Konvergenz in einem Panel von Volkswirtschaften. Die dadurch ersichtliche Inhomogenität diverser Panels führt zur Cluster Analyse selbiger. Mit zwei verschiedenen Cluster Algorithmen werden die Panels in konvergente Clubs unterteilt. Die untersuchten Panels sind ein Welt Panel, ein Afrika Panel, ein Europa Panel sowie eine Auswahl von 20 hoch entwickelten OECD Ländern.
description: In this thesis the so called convergence hypothesis is investigated using methods proposed by Phillips and Sul (2007 and 2009). The neoclassical growth model, more precisely, the extended Solow Model is the starting point of the analysis. Theoretical work leads to a non linear factor model, describing the log real income with a common factor describing the common development of all countries in a panel and an idiosyncratic component, measuring the relative share of the common component. As the idiosyncratic factor cannot be estimated straightly, so called relative transition paths are used for a graphical and quantitative analysis. Phillips and Sull propose the log-t convergence test for measuring convergence in a panel of economies. The observed inhomogeneity in the panels is the incentive for the cluster analysis. With two different clustering algorithms, the panels are divided into several convergent clubs. The panels analysed are a World Panel, an Africa Panel, a Europe Panel and a selection of 20 high developed OECD countries.

description: We report measurements on the H$^{+}$ + H$^{+}$ fragmentation channel following direct single-photon double ionization of neutral NH$_{3}$ at 61.5 eV, where the two photoelectrons and two protons are measured in coincidence using 3-D momentum imaging. We identify four dication electronic states that contribute to H$^{+}$ + H$^{+}$ dissociation, based on our multireference configuration-interaction calculations of the dication potential energy surfaces. The extracted branching ratios between these four dication electronic states are presented. Of the four dication electronic states, three dissociate in a concerted process, while the fourth undergoes a sequential fragmentation mechanism. We find evidence that the neutral NH fragment or intermediate NH$^+$ ion is markedly ro-vibrationally excited. We also identify differences in the relative emission angle between the two photoelectrons as a function of their energy sharing for the four different dication states, which bare some similarities to previous observations made on atomic targets.

description: Accurate description of bacterial dynamics is an important factor for understanding the bacterial cell cycle. Traditionally direct observation of cell cycle dynamics using light microscopy has been restricted by the diraction limit. In recent years a number of super-resolution techniques have been developed allowing to overcome these limitations. However, time-lapse imaging of single cells is challenging due to photobleaching from prolonged illumination and cell movement between images. In addition, some dyes used in these techniques require the bacteria to be fxed prior to microscopy. This thesis explores the possibilities to reconstruct a pseudo-temporal trajectory from static images of cell populations and compares them to lower resolution single cell time lapse microscopy. Results indicate that pseudo-temporal reconstruction can provide a good approximation of the average development trajectories provided a suffcient number of cells in each cell cycle phase is available for analysis.
title: Building An Identity : Two Noblewomen In England 1566-1666
Creators: name: Gladstone, Helen Crawford
Publisher: name: The Open University
Year: 1990

description: BUILDING AN IDENTITY is a broad based study of the monuments which two female patrons built from 1566 to 1666. It probes the impulse to commemorate, considers why memorials took the form that they did, and takes account of the social conventions which provided a framework for the behaviour of these patrons. Their reasons for commemoration provided a key to the comprehension of funeral monuments, whose forms and epitaphs went beyond remembering the worthy dead with a memorial, to a quite specific view of the deceased, which served these patrons' purposes of promoting their own identities in eternal stone in the public spaces of churches. The patronage of several monuments by Elizabeth Cooke, annotated with copious epitaphs, offered a repeated opportunity to observe the thinking behind her commemoration of members of her family. Visual evidence was greatly extended by substantial documentation of her career. Repeated expenditure on monuments by this woman called for an external perspective on her behaviour by investigation of the purposes of another patron. This was provided by Anne Clifford, who set up an even longer series of monuments, extending her commemoration from family to lower ranking people who were significant in sustaining her perception of her own identity. Because both patrons of multiple monuments were women, and so far as it is now possible to establish, these were the only female patrons of long series of memorials in England at this period, the study investigated gender status to find out how their patronage fell within accepted female practice and how they extended the domestic roles assigned to high ranking Englishwomen. This study of their lives and commissions showed these women to be assuming head of family functions, through which they claimed high rank for themselves, which was only marginally affected by their consciousness of inferior female gender.

description: An implementation of A Common Tracking Software (ACTS) toolkit for signal electron reconstruction for the COMET muon to electron conversion experiment is discussed. The COMET experiment in J-PARC, Japan, will search for neutrinoless conversion of muons into electrons in the field of an aluminium nucleus, a lepton flavour violating process, aiming target sensitivity of $10^{-17}$. To achieve its scientific goals, the experiment requires a reconstructed momentum resolution of lower than 150 keV/c. For the first time by applying ACTS to signal events in the 100 MeV energy range with multiple-turn trajectories in the presence of background events, it is found that the reconstruction efficiency is around 14\% with no fake reconstructed events. The implementation details, performance, and issues of ACTS in the context of COMET are presented.

Diese Arbeit beschäftigt sich mit dem Aufbau eines Verallgemeinerten Linearen Modelles, den Verteilungen der Exponentialfamilie, die auch für Versicherungsmodelle relevant sind, sowie den Kennzahlen der Anpassungsgüte der Modelle. Mit Hilfe eines statistischen Tools wird eine Datenbasis der Versicherungssparte KFZ-Haftpflicht verarbeitet und eine Tarifstruktur erstellt. Dabei erhält man eine Risikonettoprämie sowie Zu- und Abschlagsfaktoren um die individuelle Prämie für einen Versicherungsnehmer zu erhalten. Da Daten eine gewisse Unsicherheit und Fehlerquote enthalten, wird zusätzlich empfohlen, einen Risikoaufschlag zu erwirtschaften. Dieser Risikoaufschlag kann unter anderem mit der Gausschen Fehlerfortpflanzung berechnet werden.
description: For an insurance company, the pricing of its products is an essential part of the business. A useful statistical aid for that process are generalized linear models. They are a generalization of the classical linear model, which corresponds to a linear regression, which has some helpful properties. This thesis deals with the construction of a generalized linear model, the distributions of the exponential family, which are also relevant for insurance models, as well as the key figures of the adaptation quality of the models. Using a statistical tool, a database is processed and a tariff structure is created. In this process a risk premium net is calculated with additional factors to calculate the individual premium for a policyholder. Since data contain a certain uncertainty and error rate, it is recommended to generate an additional risk premium. This risk premium can be calculated with the gaussian error propagation.
The infrared spectral energy distributions of star-forming galaxies
Creators: name: Sajina, Anna
Publisher: name: University of British Columbia
Year: 2010

description: The spectral energy distribution (SED) is one of the key observational features of galaxies. It allows us both to gain insight into the physical properties of galaxies and compare populations selected at different wavelengths or redshifts. In this thesis we address all steps in the study of SEDs, including how to constrain them from the available data, how to derive the underlying properties of the galaxies, and how to use them to interpret and predict survey data. The first step is accomplished with a phenomenological SED model and a Markov Chain Monte Carlo fitting technique. General trends in the mid-IR spectra of a wide range of galaxy types are discussed as well as argument made for considering a continuum of SED shapes, as opposed to discrete templates. Based on this approach, predictions are made for the evolution of diagnostic mid-IR colours. We extend our model into the far-IR/sub-mm regime, and apply it to a sample of 22 170 /μm-selected, star-forming galaxies representing the brightest ~ 10% of the Cosmic Infrared Background (CIB) contributors. The sample spans the range of infrared luminosity log(L[sub IR]/L[sub Θ]) ~ 10-12 and redshift z ~0-l. From these model fits and standard relations we derive a host of underlying physical properties including: stellar mass, opacity, dust mass, dust temperature. These allow for direct comparisons with other samples of optical- or IR-selected star-forming galaxies, allowing us to explore in detail the nature of our sample. We find that, although not actually starbursts, these galaxies have enhanced SFRs compared with local quiescent spirals. Our highest luminosity sources are found to be colder than local templates, which is potentially explained by their having more extended star-formation activity than observed in local ULIGs. We conclude by addressing the implications of our study to other IR-selected samples. In particular we discuss the possible nature of the remaining ~ 90% of the CIB contributors. This thesis represents the first systematic fitting of SEDs of a sample of galaxies across the entire infrared wavelength range. This work is also the first use of Markov Chain Monte Carlo (MCMC) in infrared SED fitting, hence our error bars are much better defined and more believable than from earlier studies. The approach we take here can potentially be applied to larger samples from future multi-wavelength surveys extending to higher redshifts. This would allow for far greater precision in galaxy evolution studies than is currently possible.

description: We present a new fast radio burst (FRB) at 920 MHz discovered during commensal observations conducted with the Australian Square Kilometre Array Pathfinder (ASKAP) as part of the Commensal Real-time ASKAP Fast Transients (CRAFT) survey. FRB 191001 was detected at a dispersion measure (DM) of 506.92(4) pc cm$^{-3}$ and its measured fluence of 143(15) Jy ms is the highest of the bursts localized to host galaxies by ASKAP to date. The subarcsecond localization of the FRB provided by ASKAP reveals that the burst originated in the outskirts of a highly star-forming spiral in a galaxy pair at redshift $z=0.2340(1)$. Radio observations show no evidence for a compact persistent radio source associated with the FRB 191001 above a flux density of $15 μ$Jy. However, we detect diffuse synchrotron radio emission from the disk of the host galaxy that we ascribe to ongoing star formation. FRB 191001 was also detected as an image-plane transient in a single 10 s snapshot with a flux density of 19.3 mJy in the low-time-resolution visibilities obtained simultaneously with CRAFT data. The commensal observation facilitated a search for repeating and slowly varying radio emissions 8 hr before and 1 hr after the burst. We found no variable radio emission on timescales ranging from 1 ms to 1.4 hr. We report our upper limits and briefly review FRB progenitor theories in the literature that predict radio afterglows. Our data are still only weakly constraining of any afterglows at the redshift of the FRB. Future commensal observations of more nearby and bright FRBs will potentially provide stronger constraints.

description: We present spectroscopic measurements and detailed theoretical analysis of inner-shell LMn and LNn (n $\geq$ 4) dielectronic resonances in highly-charged M-shell ions of tungsten. The x-ray emission from W$^{49+}$ through W$^{64+}$ was recorded at the electron beam ion trap (EBIT) facility at the National Institute of Standards and Technology (NIST) with a high-purity Ge detector for electron beam energies between 6.8 keV and 10.8 keV. The measured spectra clearly show the presence of strong resonance features as well as direct excitation spectral lines. The analysis of the recorded spectra with large-scale collisional-radiative (CR) modeling of the EBIT plasma allowed us to unambiguously identify numerous dielectronic resonances associated with excitations of the inner-shell 2s$_{1/2}$, 2p$_{1/2}$, and 2p$_{3/2}$ electrons.

description: Even after the discovery of neutrino flavour oscillations, based on data from atmospheric, solar, reactor, and accelerator experiments, many characteristics of the neutrino remain unknown. Only the neutrino square-mass differences and the mixing angle values have been estimated, while the value of each mass eigenstate still hasn't. Its nature (massive Majorana or Dirac particle) is still escaping. Neutrinoless double beta decay ($0ν$-DBD) experimental discovery could be the ultimate answer to some delicate questions of elementary particle and nuclear physics. The Majorana description of neutrinos allows the $0ν$-DBD process, and consequently either a mass value could be measured or the existence of physics beyond the standard should be confirmed without any doubt. As expected, the $0ν$-DBD measurement is a very difficult field of application for experimentalists. In this paper, after a short summary of the latest results in neutrino physics, the experimental status, the R&D projects, and perspectives in $0ν$-DBD sector are reviewed.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

title: The Music Of Peter Maxwell Davies Based On The Writings Of George Mackay Brown
Creators: name: Warnaby, John Surtees
Publisher: name: The Open University
Year: 1991

description: The primary objective has been to demonstrate the stylistic changes in Maxwell Davies's music which have resulted from his settings of Mackay Browqn texts. This has involved a comparison with some of the composer's earlier works, particularly those with literary associations, and includes a discussion of the problems encountered when responding to 'expressionist' poetry. The differences between 'modernism' in music and in 1iterature have also been considered with reference to some aspects of literary theory. After a survey of Maxwell Davies's Mackay Brown settings in several genres, illustrating the extent to which the composer has been influenced by Mackay Brown's approach to narrative, especially with regard to his use of the multiple viewpoint, attention is focused on Maxwell Davies's Black Pentecost and Second Symphony. This comparison shows that the technique employed for a Mackay Brown setting and that for a large-scalke symphony are essentially the same, and that the differences are a matter of style, rather than compositional method. The thesis then develops the argument that because of the variety of styles employed by Maxwell Davies, conventional analysis has failed to deal adequately with all aspects of his music, most notably when texts are involved. Thus it is suggested that literary concepts can provide valuable illumination, particularly as regards the composer's use of 'defamiliarization' to creative a subversive effect. This device has frequently been employed in scores reflecting Maxwell Davies's attitude to cultural, political, or social issues - again developing aspects of Mackay Brown's influence - and in the light of recent trends in music analysis and literary theory, it forms the basis of a discussion of Resurrection, which was conceived partly in response to the principal themes of Thomas Mann's Doktor Faustus. However, while Mackay Brown indirectly influenced the structure of the opera, the stylistic changes

description: Deep defects in wide band gap semiconductors have emerged as leading qubit candidates for realizing quantum sensing and information applications. Due to the spatial localization of the defect states, these deep defects can be considered as artificial atoms/molecules in a solid state matrix. Here we show that unlike single-particle treatments, the multiconfigurational quantum chemistry methods, traditionally reserved for atoms/molecules, accurately describe the many-body characteristics of the electronic states of these defect centers and correctly predict properties that single-particle treatments fail to obtain. We choose the negatively charged nitrogen-vacancy (NV$^-$) center in diamond as the prototype defect to study with these techniques due to its importance for quantum information applications and because its properties are well-known, which makes it an ideal benchmark system. By properly accounting for electron correlations and including spin-orbit coupling and dipolar spin-spin coupling in the quantum chemistry calculations, for the NV$^-$ center in diamond clusters, we are able to: (i) show the correct splitting of the ground (first-excited) triplet state into two levels (four levels), (ii) calculate zero-field splitting values of the ground and excited triplet states, in good agreement with experiment, and (iii) calculate the energy differences between ground and exited spin-triplet and spin-singlet states, as well as their ordering, which are also found to be in good agreement with recent experimental data. The numerical procedure we have developed is general and it can screen other color centers whose properties are not well known but promising for applications.

description: An ensemble of particles in thermal equilibrium at temperature $T$, modeled by Nosè-Hoover dynamics, moves on a triangular lattice of oriented semi-disk elastic scatterers. Despite the scatterer asymmetry a directed transport is clearly ruled out by the second law of thermodynamics. Introduction of a polarized zero mean monochromatic field creates a directed stationary flow with nontrivial dependence on temperature and field parameters. We give a theoretical estimate of directed current induced by a microwave field in an antidot superlattice in semiconductor heterostructures.

Photonic bandstructure in semiconductor slab waveguides with strong two-dimensional texture
Creators: name: Pacradouni, Vighen
Publisher: name: University of British Columbia
Year: 2010

description: Fabrication techniques were developed and used to realize sub-100 nm-thick semiconductor membranes that contain two-dimensional (2D) square arrays of holes that completely penetrate the membrane. With the pitch of the arrays on the order of 500 nm, broadband optical reflectivity spectra obtained from these "2D planar photonic crystal membranes" reveal resonant features with energies and linewidths that disperse as the in-plane momentum (angle of incidence) of the exciting radiation is varied in the near-infrared. A numerical solution of Maxwell’s equations was developed to interpret these reflectivity spectra in terms of a "photonic bandstructure" for electromagnetic modes localized in the vicinity of the porous membrane. A complete understanding of the complex (energy and lifetime) dispersion and polarization properties of this interesting new class of optical materials was obtained. It is shown that this bandstructure can be largely explained by applying symmetry considerations to the renormalization of slab waveguide modes by the high index contrast 2D scattering potential.

description: With the signing of the EU-ACP Economic Partnership Agreements (EPAs) in January 2009, Uganda as a member of the ACP, should endeavour to re-strategize itself to benefit from the opportunities such trading blocks create through increased trade. Trade is likely to increase with EPA in place and this is likely to lead to biodiversity conservation challenges amidst the need for increased production. Uganda signed and ratified the United Nations Convention on Biological Diversity (CBD) on 12th June 1992 and 8th September 1993 respectively. The objectives of CBD are the conservation of biodiversity; sustainable use of bio diversity; and the fair and equitable sharing of benefits arising from the utilization of genetic resources. Although Government has made significant progress in achieving these objectives, balancing trade and biodiversity under EPA presents challenges. In this brief we focus on fresh fruits and vegetables production and suggest some trade options that would be beneficial under EPA and also ways on how to mitigate biodiversity loss. In addition, some key policy interventions that can lead to sustainable trade in fresh fruits and vegetables are recommended.
title: The achievement of Ford Madox Ford as editor
Creators: name: Tomlinson, Nora
Publisher: name: The Open University
Year: 1996

description: This thesis challenges the conventional opinion that Ford Madox Ford was a great editor. It establishes criteria by which an editor can be judged; these are the literary and cultural opinions on which a review operates, an awareness of the needs of readers of a review as revealed in its style and content, and the way in which a review is managed. These criteria are applied to three different, though overlapping fields of enquiry. Firstly, the thesis examines how far Ford's editorial practice was consistent with his own literary and critical principles as expressed through a long and varied writing career. Secondly, it places the two reviews edited by Ford in the context of the society which produced them, English Review in London between 1908 and 1910, and The Transatlantic Review in Paris in 1924, and compares these two reviews with a wide range of contemporary cultural journals on the basis of the three criteria outlined above. Finally the study compares Ford's achievement as editor of The English Review and The Transatlantic Review. It concludes that while Ford was a good editor in some respects, he was not the great editor which is so often claimed for him.

description: With the signing of the EU-ACP Economic Partnership Agreements (EPAs) in 2009, the Government of Uganda as a member of the ACP, should endeavour to re-strategize itself to benefit from the opportunities such trading blocks create through increased trade. While Uganda ratified the United Nations Convention on Biological Diversity (CBD), in 1993 considerable efforts need to be put into its implementation. Trade is likely to increase with EPAs in place and this will lead to biodiversity conservation concerns amidst the need for increased production. Biodiversity concerns have been of little interest in relation to trade, thus, in here, we focus on cut flower production and suggest some trade options that are beneficial while mitigating biodiversity loss. In addition, we propose policies that can lead to (actionable points) for cut flower farmers and policy makers.

description: Although BERT-style encoder models are heavily used in NLP research, many researchers do not pretrain their own BERTs from scratch due to the high cost of training. In the past half-decade since BERT first rose to prominence, many advances have been made with other transformer architectures and training configurations that have yet to be systematically incorporated into BERT. Here, we introduce MosaicBERT, a BERT-style encoder architecture and training recipe that is empirically optimized for fast pretraining. This efficient architecture incorporates FlashAttention, Attention with Linear Biases (ALiBi), Gated Linear Units (GLU), a module to dynamically remove padded tokens, and low precision LayerNorm into the classic transformer encoder block. The training recipe includes a 30% masking ratio for the Masked Language Modeling (MLM) objective, bfloat16 precision, and vocabulary size optimized for GPU throughput, in addition to best-practices from RoBERTa and other encoder models. When pretrained from scratch on the C4 dataset, this base model achieves a downstream average GLUE (dev) score of 79.6 in 1.13 hours on 8 A100 80 GB GPUs at a cost of roughly $20. We plot extensive accuracy vs. pretraining speed Pareto curves and show that MosaicBERT base and large are consistently Pareto optimal when compared to a competitive BERT base and large. This empirical speed up in pretraining enables researchers and engineers to pretrain custom BERT-style models at low cost instead of finetune on existing generic models. We open source our model weights and code.
