description: We prove that a Pfaffian system with coefficients in the critical space $L^2_\mathrm{loc}$ on a simply connected open subset of $\mathbb{R}^2$ has a non-trivial solution in $W^{1,2}_\mathrm{loc}$ if the coefficients are antisymmetric and satisfy a compatibility condition. As an application of this result, we show that the fundamental theorem of surface theory holds for prescribed first and second fundamental forms of optimal regularity in the classes $W^{1,2}_\mathrm{loc}$ and $L^2_\mathrm{loc}$, respectively, that satisfy a compatibility condition equivalent to the Gauss-Codazzi-Mainardi equations. Finally, we give a weak compactness theorem for surface immersions in the class $W^{2,2}_\mathrm{loc}$.

description: A correspondence between 1) rank 2 completely integrable systems of Jacobians of algebraic curves and 2) (holomorphically) symplectic surfaces was established in a previous paper by the first author. A more general abelian variety that occurs as a Liouville torus of integrable systems is a prym variety associated to a triple (S,W,V) consisting of a curve S, a finite group W of automorphisms of S and an integral representation V. Often W is a Weyl group of a reductive group and V is the root lattice. We establish an analogous correspondence between: i) Rank 2 integrable systems whose Liouville tori are generalized prym varieties Prym(S_u,W,V) of a family of curves S_u, u in U. ii) Varieties X of dimension 1+dim(V) with a W-action and an invariant V-valued 2-form. If V is one dimensional X is a symplectic surface. We obtain a rigidity result: When the dimension of V is at least 2, under mild additional assumptions, all the quotient curves $S_u/W$ are isomorphic to a fixed curve C. This rigidity result imposes considerable constraints on the variety X: X admits a W-invariant fibration to C and the generic fiber has an affine structure modeled after V. Examples discussed include: Hitchin systems, reduced finite dimensional coadjoint orbits of loop algebras, and principal bundles over elliptic K3 surfaces.

Platandriina Hanley, 2002a:301. Hanley, in press b.
 Type-genus: Platandria Casey, 1893.
 Diagnosis: In addition to the characters of the tribe, this subtribe is characterized by 4-5-5 or 4-4-5 tarsal formula; narrowly separated mesocoxae; ligula short, with a relatively deep fork. Secondary sexual characteristics often present in males as small carinae or denticles on abdominal terga IV and VIII, and rarely VII (never the elytra).
 Comments: This subtribe currently consists of seven genera and 26 described species distributed in the Afrotropical, Nearctic, Neotropical, and Oriental regions, with one species of Omoplandria described from Japan. Based on limited label data from few genera, I hypothesize that members of this lineage occur in association with flowers where they are most likely feeding on nectar or pollen.

description: In this paper we present an incremental variant of the Twin Support Vector Machine (TWSVM) called Fuzzy Bounded Twin Support Vector Machine (FBTWSVM) to deal with large datasets and learning from data streams. We combine the TWSVM with a fuzzy membership function, so that each input has a different contribution to each hyperplane in a binary classifier. To solve the pair of quadratic programming problems (QPPs) we use a dual coordinate descent algorithm with a shrinking strategy, and to obtain a robust classification with a fast training we propose the use of a Fourier Gaussian approximation function with our linear FBTWSVM. Inspired by the shrinking technique, the incremental algorithm re-utilizes part of the training method with some heuristics, while the decremental procedure is based on a scored window. The FBTWSVM is also extended for multi-class problems by combining binary classifiers using a Directed Acyclic Graph (DAG) approach. Moreover, we analyzed the theoretical foundations properties of the proposed approach and its extension, and the experimental results on benchmark datasets indicate that the FBTWSVM has a fast training and retraining process while maintaining a robust classification performance.

description: We reconsider the Standard Model interactions of ultra-high energy neutrinos with matter. The next to leading order QCD corrections are presented for charged-current and neutral-current processes. Contrary to popular expectations, these corrections are found to be quite substantial, especially for very large (anti-) neutrino energies. Hence, they need to be taken into account in any search for new physics effects in high-energy neutrino interactions. In our extrapolation of the parton densities to kinematical regions as yet unexplored directly in terrestrial accelerators, we are guided by double asymptotic scaling in the large Q^2 and small Bjorken x region and to models of saturation in the low Q^2 and low x regime. The sizes of the consequent uncertainties are commented upon. We also briefly discuss some variables which are insensitive to higher order QCD corrections and are hence suitable in any search for new physics.

description: Channelrhodopsin-1 from Chlamydomonas augustae (CaChR1) is a light-activated cation channel, which is a promising optogenetic tool. We show by resonance Raman spectroscopy and retinal extraction followed by high pressure liquid chromatography (HPLC) that the isomeric ratio of all-trans to 13-cis of solubilized channelrhodopsin-1 is with 70:30 identical to channelrhodopsin-2 from Chlamydomonas reinhardtii (CrChR2). Critical frequency shifts in the retinal vibrations are identified in the Raman spectrum upon transition to the open (conductive P2380) state. Fourier transform infrared spectroscopy (FTIR) spectra indicate different structures of the open states in the two channelrhodopsins as reflected by the amide I bands and the protonation pattern of acidic amino acids.

Using the formalism based on the momentum representation we calculated all the genuine twist-3 terms of quark contributions to gamma_T^* --> rho_T amplitude. We found that these terms can not be factorized owing to the existence of the infrared divergencies in the amplitude of hard sub-processes.

description: We present the Simplified Lissajous Ellipse Fitting (SLEF) method for the calculation of the random phase step and the phase distribution from two phase-shifted interferograms. We consider interferograms with spatial and temporal dependency of background intensities, amplitude modulations and noise. Given these problems, the use of the Gabor Filters Bank (GFB) allows us to filter--out the noise, normalize the amplitude and eliminate the background. The normalized patterns permit to implement the SLEF algorithm, which is based on reducing the number of estimated coefficients of the ellipse equation, from five terms to only two. Our method consists of three stages. First, we preprocess the interferograms with GFB methodology in order to normalize the fringe patterns. Second, we calculate the phase step by using the proposed SLEF technique and third, we estimate the phase distribution using a two--steps formula. For the calculation of the phase step, we present two alternatives: the use of the Least Squares (LS) method to approximate the values of the coefficients and, in order to improve the LS estimation, a robust estimation based on the Leclerc's potential. The SLEF method's performance is evaluated through synthetic and experimental data to demonstrate its feasibility.

description: This research paper attempts to assess European responses to the Arab uprisings and, in particular, the introduced change in the EU policy towards its Southern Neighborhood. In specific terms, to what extent do security and strategic considerations still constitute the basis in the EU’s “fundamental revision” of its policy in the Southern Neighborhood? And to what extent is the need to safeguard security and strategic interests undermining an authentic EU role in building deep democracy in the region? The presented analyses provide a profound scrutiny and assessment of the new version of the European Neighborhood Policy (ENP), an empirical evidence of persisting security considerations post-2011 in Euro-Arab relations, and a more elaborated vision of future Euro-Arab relations, attempting to balance between three considerations: security, democracy, and governance. The paper argues that the EU response to revolutionary events in the Arab region has been weak and that the new version of the ENP results hollow. Wide disagreements among European capitals on how to react to Arab uprisings, the sudden influx of illegal migrants and refugees, increased energy concerns, and the rise of political Islam, especially in radical forms, appears to be the key reasons behind this weak response. The study advocates that a proactive and agile EU role in the Arab region post-2011 should not be considered as derived from a moral stance. Rather, it is urgently required as it is in Europe’s own interest. The historic events in the Arab region suggest that the EU should not merely revise its own ENP with the Southern Mediterranean. However, it should develop a comprehensive vision and an all-encompassing approach to the entire Arab region, from the West Mediterranean to the Gulf. Finally, this paper provides a number of policy recommendations, attempting to offer a frame for such a vision.
Simple Bounds for One-shot Pure-State Distillation in General Resource Theories

description: We present bounds for distilling many copies of a pure state from an arbitrary initial state in a general quantum resource theory. Our bounds apply to operations that are able to generate no more than a $δ$ amount of resource, where $δ\geq 0$ is a given parameter. To maximize applicability of our upper bound, we assume little structure on the set of free states under consideration besides a weak form of superadditivity of the function $G_{min}(ρ)$, which measures the overlap between $ρ$ and the set of free states. Our bounds are given in terms of this function and the robustness of resource. Known results in coherence and entanglement theory are reproduced in this more general framework.

description: The aim of this paper is to examine the possibilities and challenges posed to the analysis of public policy implementation from a subnational perspective. It focuses on three central aspects: (1) the methodological opportunities offered by the subnational comparative method to understand public policy within countries; (2) the intersection of the economy and demography as conditioner of the localization of needs and the formation of spatially heterogeneous demands; and (3) the spatial specialization of provision due to variations in institutional structures and policy design. These ideas are illustrated using Brazilian social policies as cases in order to demonstrate how economic, demographic and politico-institutional characteristics at the subnational level alter the implementation of public policies and, therefore, generate inequalities of access to welfare.

A symmetry-preserving truncation of its kernel enables proofs of important results and the development of an efficacious phenomenology. We describe a model of the kernel that yields: a momentum-dependent dressed-quark propagator in fair agreement with quenched lattice-QCD results; and chiral limit values: f_pi= 68 MeV and = -(190 MeV)^3. It is compared with models inferred from studies of the gauge sector.

Thanks to this mirror, we are able to image almost the full 4$π$ emission pattern of nanometer-sized elementary dipoles and verify the alignment of the rods within the optical trap. From the motional dynamics of the emitters in the trap we infer that the single-photon emission occurs from clusters comprising several emitters. We demonstrate the optical trapping of rod-shaped quantum emitters in a configuration suitable for efficiently coupling an ensemble of linear dipoles with the electromagnetic field in free space.

Subjects: subject: Queensland education

description: This thesis answers the question: to what extent is the history of education in Queensland, Australia, a history of secularisation? Through a Foucauldian history of the present, it explores the shifting relationship between Christian and secular ideals in Queensland education from the early twentieth century through to 2017. It focuses on a series of six case studies, each of which examines a moment during which the existing relationship between Christian and secular ideals was challenged. This thesis offers a revised definition of secularisation. This definition holds that secularisation should be understood as (1) historically, culturally, and spatially specific; (2) changing and recursive; (3) situated in power relations; (4) multi-faceted and multi-scalar and (5) existing in the context of multiple modernities. Using this definition, the thesis finds that secularisation has occurred through the history of education in Queensland, despite legislative changes which continue to privilege Christianity. The key data this thesis relies upon are archival sources including letters, reports, and cabinet minutes. Other significant forms of data include newspaper sources, Census data, legislation, and Hansard reports.

Prison riots

description: Dating back to the early prisoners’ rights movement in the 1970s, there has been a nearly cyclical occurrence of unrest behind bars alongside limited coverage by media organizations. From an academic standpoint, such unrest and other prison disturbances have slowly become the subject of scholarly study. Most research has fallen into the category of “social movements in prison,” investigating the reasoning behind the occurrence of riots, violent uprisings, and general disturbances, but few have included other forms of protests such as labor strikes, hunger strikes, and sit-ins. Utilizing LexisNexis to generate a database of coverage by five of the largest newspapers across the United States, this research examines the conditions under which incarcerated persons act collectively and when they do, what kind of collective action occurs. Rooted in data derived from newspaper coverage, this study ultimately finds hunger strikes, riots, and quests for improved conditions and higher wages as leading factors of prison unrest. The results of this research better explain collective resistance and social action within prisons. Considered generalizable on a larger scale, this thesis provides an updated analysis of collective action and makes a case in support of news media publications as a conduit to tangible change.

description: This paper is devoted to a generalisation of the quantum adiabatic theorem to a nonlinear setting. We consider a Hamiltonian operator which depends on the time variable and on a finite number of parameters and acts on a separable Hilbert space of which we select a fixed basis. We study an evolution equation in which this Hamiltonian acts on the unknown vector, while depending on coordinates of the unknown vector in the selected basis, thus making the equation nonlinear. We prove existence of solutions to this equation and consider their asymptotics in the adiabatic regime, i.e. when the Hamiltonian is slowly varying in time. Under natural spectral hypotheses, we prove the existence of normalised time dependent vectors depending on the Hamiltonian only, called instantaneous nonlinear eigenvectors, and show the existence of solutions which remain close to these vectors, up to a rapidly oscillating phase, in the adiabatic regime. We first investigate the case of bounded operators and then exhibit a set of spectral assumptions under which the result extends to unbounded Hamiltonians.

Generalization through variance: how noise shapes inductive biases in diffusion models

description: How diffusion models generalize beyond their training set is not known, and is somewhat mysterious given two facts: the optimum of the denoising score matching (DSM) objective usually used to train diffusion models is the score function of the training distribution; and the networks usually used to learn the score function are expressive enough to learn this score to high accuracy. We claim that a certain feature of the DSM objective -- the fact that its target is not the training distribution's score, but a noisy quantity only equal to it in expectation -- strongly impacts whether and to what extent diffusion models generalize. In this paper, we develop a mathematical theory that partly explains this 'generalization through variance' phenomenon. Our theoretical analysis exploits a physics-inspired path integral approach to compute the distributions typically learned by a few paradigmatic under- and overparameterized diffusion models. We find that the distributions diffusion models effectively learn to sample from resemble their training distributions, but with 'gaps' filled in, and that this inductive bias is due to the covariance structure of the noisy target used during training. We also characterize how this inductive bias interacts with feature-related inductive biases.

Farmers--Political activity

description: India’s rural populations remain routinely marginalized in national policy decisions. The economic concerns of farming communities are often ignored by policy makers, with a complete lack of attention paid to systemic failures and decades of ill-governance. Perhaps the biggest manifestation of this is the country’s farmer suicide epidemic, which has been ongoing since the 1990s, having taken more than 300,000 lives. The prolonged and pervasive nature of the crisis necessitates an analysis of both the structural constraints impacting Indian agriculture as well as civil society’s response. This is especially significant considering that India is often referred to as the “world’s largest democracy.” A close analysis of today’s farmer movements, however, suggest that they are periodically inactive and largely ineffective in impacting structural change. Why? A viable explanation for this lies in the application of social movement theoretical perspectives, which point to the value of culture and identity in shaping movements. It is argued that culture, in conjunction with capacity and socio-political capital, becomes an agency of reform when leveraged to induce a sense of “collective identity” amongst participants. The value of such a hypothesis is evidenced by Indian farming communities, whereby until the 1990s, they existed as some of the most important non-parliamentary political forces across multiple states. By applying existing these theories to both historical and present-day movements within the Maharashtrian district of Wardha, the text proposes that today’s farmers stand divided, as conflicting characteristics (be it class, caste or religion) take precedence over a singular farmer identity, thereby hindering collective action and, in the process, placing limits on the politics of farmer empowerment. In doing so, it deepens understandings of how culture, collective identity and emotion cultivate political opportunities, facilitate socio-economic and political agency and ultimately lead to structural change within communities.

description: Statistical inference of multiple parameters often involves a preliminary parameter selection stage. The selection stage has an impact on subsequent estimation, for example by introducing a selection bias. The post-selection maximum likelihood (PSML) estimator is shown to reduce the selection bias and the post-selection mean-squared-error (PSMSE) compared with conventional estimators, such as the maximum likelihood (ML) estimator. However, the computational complexity of the PSML is usually high due to the multi-dimensional exhaustive search for a global maximum of the post-selection log-likelihood (PSLL) function. Moreover, the PSLL involves the probability of selection that, in general, does not have an analytical form. In this paper, we develop new low-complexity post-selection estimation methods for a two-stage estimation after parameter selection architecture. The methods are based on implementing the iterative maximization by parts (MBP) approach, which is based on the decomposition of the PSLL function into "easily-optimized" and complicated parts. The proposed second-best PSML method applies the MBP-PSML algorithm with a pairwise probability of selection between the two highest-ranked parameters w.r.t. the selection rule. The proposed SA-PSML method is based on using stochastic approximation (SA) and Monte Carlo integrations to obtain a non-parametric estimation of the gradient of the probability of selection and then applying the MBP-PSML algorithm on this approximation. For low-complexity performance analysis, we develop the empirical post-selection Cramer-Rao-type lower bound. Simulations demonstrate that the proposed post-selection estimation methods are tractable and reduce both the bias and the PSMSE, compared with the ML estimator, while only requiring moderate computational complexity.

description: This study examines the role of collective identity in nonprofit coalition-building, using critical discourse analysis of a case study of an Asian American nonprofit organizational coalition focused on advocating for community health access and equity.  The study finds that the pan-ethnic collective identity is a resource for the organizational coalition studied.  The study extends existing literature on inter-organizational studies and nonprofit organizational coalition-building through the introduction of a conceptualization or model of identity work as involving both the activation and strategic deconstruction of the pan-ethnic Asian American collective identity.  This study finds that identity work, as conceptualized, can be critical not only to sustaining a pan-ethnic coalition, but also to ensuring that a pan-ethnic coalition of nonprofit organizations embodies social work value of social justice and ethical responsibility of cultural competence and social diversity.
Inferred timescales for common envelope ejection using wide astrometric companions

description: Evolution of close binaries often proceeds through the common envelope stage. The physics of the envelope ejection (CEE) is not yet understood, and several mechanisms were suggested to be involved. These could give rise to different timescales for the CEE mass-loss. In order to probe the CEE-timescales we study wide companions to post-CE binaries. Faster mass-loss timescales give rise to higher disruption rates of wide binaries and result in larger average separations. We make use of data from Gaia DR2 to search for ultra-wide companions (projected separations $10^3$-$2\times 10^5$ a.u. and $M_2 > 0.4$ M$_\odot$) to several types of post-CEE systems, including sdBs, white-dwarf post-common binaries, and cataclysmic variables. We find a (wide-orbit) multiplicity fraction of $1.4\pm 0.2$ per cent for sdBs to be compared with a multiplicity fraction of $5.0\pm 0.2$ per cent for late-B/A/F stars which are possible sdB progenitors. The distribution of projected separations of ultra-wide pairs to main sequence stars and sdBs differs significantly and is compatible with prompt mass loss (upper limit on common envelope ejection timescale of $10^2$ years). The smaller statistics of ultra-wide companions to cataclysmic variables and post-CEE binaries provide weaker constraints. Nevertheless, the survival rate of ultra-wide pairs to the cataclysmic variables suggest much longer, $\sim10^4$ years timescales for the CEE in these systems, possibly suggesting non-dynamical CEE in this regime.

description: In this minireview, we report on our year-long EPR work, such as electron–nuclear double resonance (ENDOR), pulse electron double resonance (PELDOR) and ELDOR-detected NMR (EDNMR) at X-band and W-band microwave frequencies and magnetic fields. This report is dedicated to James S. Hyde and honors his pioneering contributions to the measurement of spin interactions in large (bio)molecules. From these interactions, detailed information is revealed on structure and dynamics of macromolecules embedded in liquid- solution or solid-state environments. New developments in pulsed microwave and sweepable cryomagnet technology as well as ultra-fast electronics for signal data handling and processing have pushed the limits of EPR spectroscopy and its multi-frequency extensions to new horizons concerning sensitivity of detection, selectivity of molecular interactions and time resolution. Among the most important advances is the upgrading of EPR to high magnetic fields, very much in analogy to what happened in NMR. The ongoing progress in EPR spectroscopy is exemplified by reviewing various multi-frequency electron–nuclear double-resonance experiments on organic radicals, light- generated donor–acceptor radical pairs in photosynthesis, and site- specifically nitroxide spin-labeled bacteriorhodopsin, the light-driven proton pump, as well as EDNMR and ENDOR on nitroxides. Signal and resolution enhancements are particularly spectacular for ENDOR, EDNMR and PELDOR on frozen-solution samples at high Zeeman fields. They provide orientation selection for disordered samples approaching single-crystal resolution at canonical g-tensor orientations—even for molecules with small g-anisotropies. Dramatic improvements of EPR detection sensitivity could be achieved, even for short-lived paramagnetic reaction intermediates. Thus, unique structural and dynamic information is revealed that can hardly be obtained by other analytical techniques. Micromolar concentrations of sample molecules have become sufficient to characterize stable and transient reaction intermediates of complex molecular systems—offering exciting applications for physicists, chemists, biochemists and molecular biologists.
