description: Gaussian processes (GP) are a well studied Bayesian approach for the optimization of black-box functions. Despite their effectiveness in simple problems, GP-based algorithms hardly scale to high-dimensional functions, as their per-iteration time and space cost is at least quadratic in the number of dimensions $d$ and iterations $t$. Given a set of $A$ alternatives to choose from, the overall runtime $O(t^3A)$ is prohibitive. In this paper we introduce BKB (budgeted kernelized bandit), a new approximate GP algorithm for optimization under bandit feedback that achieves near-optimal regret (and hence near-optimal convergence rate) with near-constant per-iteration complexity and remarkably no assumption on the input space or covariance of the GP. We combine a kernelized linear bandit algorithm (GP-UCB) with randomized matrix sketching based on leverage score sampling, and we prove that randomly sampling inducing points based on their posterior variance gives an accurate low-rank approximation of the GP, preserving variance estimates and confidence intervals. As a consequence, BKB does not suffer from variance starvation, an important problem faced by many previous sparse GP approximations. Moreover, we show that our procedure selects at most $\tilde{O}(d_{eff})$ points, where $d_{eff}$ is the effective dimension of the explored space, which is typically much smaller than both $d$ and $t$. This greatly reduces the dimensionality of the problem, thus leading to a $O(TAd_{eff}^2)$ runtime and $O(A d_{eff})$ space complexity.

description: The development of the larval stages of the Tetraphyllidean tapeworms is widely unknown. It is therefore tried to persue the cycle for the species Acanthobothrium coronatum (Rudolphi), a common tapeworm of the dogfish (Scylliorhinus canicula Cuv.) and some other sharks and skates. In 100 examined pilchards and anchovies numerous individuals of the so-called "Scolex pleuronectis Müller", a plerocerous Tetraphyllidean-larva, are found. The infected clupeids were fed to isolated sharks, which, finally opened, contained nothing but hundreds of the aboven nominated parasite. The way of the youngest stages is described. A coracid is not yet found but a small plerocercoid "Scolex" in copepodes. The development therefore seems to run about a first host, a copepode, which is eaten by the second, a teleostean pelagically living fish, which itself is devoured by a rapacious fish, mostly a shark, the definitive host, in other cases by another teleostean fish or a cephalopod, but these do nothing than "transport" the "Scolex" into the only definitive host, a shark or skate.

Type species
Luperodes tuberculatus Blake, 1942, by present designation.
Diagnosis
In this genus, the anterior margin of the pronotum is fringed by a row of short setae, the basal margin of the pronotum is equipped with a fine bead, and the second abdominal ventrite of the male is equipped with two short horns (Fig. 201). See the following key for additional diagnostic characters.
Etymology
The name ‘ Cornuventer ’ is Latin for ‘horn belly’, and it refers to the abdominal appendages of the male. It should be treated as a male noun.

description: We propose a simple realization of hybrid inflation in supergravity, which does not require any unnaturally small parameters. Inflation in this scenario is relatively short, and inflationary density perturbations fall down on large scales, which corresponds to a blue spectrum with n > 1. Superheavy strings which are formed after inflation in this scenario produce density perturbations of comparable magnitude. In this mixed perturbation (MP) model one may have microwave anisotropy produced by strings and galaxy formation due to inflationary perturbations.

description: The state-of-the-art approaches in Generative Adversarial Networks (GANs) are able to learn a mapping function from one image domain to another with unpaired image data. However, these methods often produce artifacts and can only be able to convert low-level information, but fail to transfer high-level semantic part of images. The reason is mainly that generators do not have the ability to detect the most discriminative semantic part of images, which thus makes the generated images with low-quality. To handle the limitation, in this paper we propose a novel Attention-Guided Generative Adversarial Network (AGGAN), which can detect the most discriminative semantic object and minimize changes of unwanted part for semantic manipulation problems without using extra data and models. The attention-guided generators in AGGAN are able to produce attention masks via a built-in attention mechanism, and then fuse the input image with the attention mask to obtain a target image with high-quality. Moreover, we propose a novel attention-guided discriminator which only considers attended regions. The proposed AGGAN is trained by an end-to-end fashion with an adversarial loss, cycle-consistency loss, pixel loss and attention loss. Both qualitative and quantitative results demonstrate that our approach is effective to generate sharper and more accurate images than existing models. The code is available at https://github.com/Ha0Tang/AttentionGAN.

The proposed strategy, acquaintance immunization, calls for the immunization of random acquaintances of random nodes (individuals). The strategy requires no knowledge of the node degrees or any other global knowledge, as do targeted immunization strategies. We study analytically the critical threshold for complete immunization. We also study the strategy with respect to the susceptible-infected-removed epidemiological model. We show that the immunization threshold is dramatically reduced with the suggested strategy, for all studied cases.

The causal set approach to quantum gravity
Creators: name: Surya, Sumati
Publisher: name: arXiv
Year: 2019
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The causal set theory (CST) approach to quantum gravity postulates that at the most fundamental level, spacetime is discrete, with the spacetime continuum replaced by locally finite posets or "causal sets". The partial order on a causal set represents a proto-causality relation while local finiteness encodes an intrinsic discreteness. In the continuum approximation the former corresponds to the spacetime causality relation and the latter to a fundamental spacetime atomicity, so that finite volume regions in the continuum contain only a finite number of causal set elements. CST is deeply rooted in the Lorentzian character of spacetime, where a primary role is played by the causal structure poset. Importantly, the assumption of a fundamental discreteness in CST does not violate local Lorentz invariance in the continuum approximation. On the other hand, the combination of discreteness and Lorentz invariance gives rise to a characteristic non-locality which distinguishes CST from most other approaches to quantum gravity. In this review we give a broad, semi-pedagogical introduction to CST, highlighting key results as well as some of the key open questions. This review is intended both for the beginner student in quantum gravity as well as more seasoned researchers in the field.

description: Cold-welding of steel can be achieved by putting sheets of softer metals between the two steel pieces so that the sheet material and the steel as well will be deformed. In experiments with aluminium sheets of different thicknesses the best results - tensile strength of the joints 10 to 20 kg/mm^2 - were obtained when applying a thickness of 3 or 4mm. With tin of variable thicknesses a tensile strength of 4 to 8 kg/mm^2 and with copper sheets a value of 14 to 26 kg/mm^2 could be obtained. Our experiments showed that the deformation of the steel was promoted by the interposed softer metal. Fracture occured in the contact zone of the two metals. However thin iron particles were torn off with growing deformation and growing thickness of the sheet material, i.e. aluminium or copper.

description: In Pakistan, the issue of religious freedom is deeply embedded in the trajectory of the political construction of religious identity, a process that has caused severe violations of human rights for many groups, particularly the Ahmadiyya Muslim Community. This community has been historically excluded and discriminated by law and society on the basis of religious distinction. The question of exclusion and persecution may be unpacked through a critical analysis of the role of secularization, and particular variants of secularism exclusive to non-Western states. The objective of this paper will be to address the difficulty of applying a simplistic rendition of a Western template of secularization in Pakistan and the difficulty of repair. I will argue that the vision of Muhammad Ali Jinnah, the primary founding father of Pakistan, had been the most prime example of how both secularism and religious moral ethos may be negotiated to yield a form of secularism that is exclusive to non-Western states with regards to religious identity. It is this framework that ought to be kept in mind when approaching the Ahmadi issue today and formulating solutions.

description: Since the 1990s, a powerful feminist movement has emerged in Iran led by women who are challenging traditional authority and re-interpreting the Quran for themselves. The way this movement evolves will determine the future direction and development of the women’s right movement in Iran and in the larger Muslim world. In this thesis, I examine the life of two influential Iranian Islamic feminists, Shahla Sherkat and Azam Taleghani, in order to understand and assess their strategies in terms of expanding women’s rights in Iran. This paper begins by providing a brief discussion of the twentieth century social and political transformation in Iran that propelled Sherkat and Taleghani to get involved in the Islamic feminism movement in Iran. Next, it discusses how the two women relate Islam with Feminism, how they approached the Quran as a basis for reform, and how they expanded the presence of women in the political sphere of Iran. Through this thesis, I hope to show that change is happening – and more often that not, it is led by Muslim women.
Transport properties of kicked and quasi-periodic Hamiltonians

description: We study transport properties of Schrödinger operators depending on one or more parameters. Examples include the kicked rotor and operators with quasi-periodic potentials. We show that the mean growth exponent of the kinetic energy in the kicked rotor and of the mean square displacement in quasi-periodic potentials is generically equal to 2: this means that the motion remains ballistic, at least in a weak sense, even away from the resonances of the models. Stronger results are obtained for a class of tight-binding Hamiltonians with an electric field $E(t)= E_0 + E_1\cosωt$. For $$ H=\sum a_{n-k}(\mid n-k>< n-k\mid) + E(t)\mid n>3/2)$ we show that the mean square displacement satisfies $\bar{}\geq C_εt^{2/(ν+1/2)-ε}$ for suitable choices of $ω, E_0$ and $E_1$. We relate this behaviour to the spectral properties of the Floquet operator of the problem.

Purity of the stratification by Newton polygons and Frobenius-periodic vector bundles

Subjects: subject: Mathematics

description: This thesis includes two parts. In the first part, we show a purity theorem for stratifications by Newton polygons coming from crystalline cohomology, which says that the family of Newton polygons over a noetherian scheme have a common break point if this is true outside a subscheme of codimension bigger than 1. The proof is similar to the proof of [dJO99, Theorem 4.1]. In the second part, we prove that for every ordinary genus-2 curve X over a finite field k of characteristic 2 with automorphism group Z/2Z × S_3, there exist SL(2,k[[s]])-representations of π_1(X) such that the image of π_1(X^-) is infinite. This result produces a family of examples similar to Laszlo's counterexample [Las01] to a question regarding the finiteness of the geometric monodromy of representations of the fundamental group [dJ01].

description: In a previous paper I showed that a classical scalar potential with $V''/V \sim 1$ can be sufficiently flattened by quantum corrections to give rise to slow-roll inflation. In this paper I give a hybrid inflation implementation of that idea which can naturally produce a spectral index in the observationally viable range even for $V^{1/4} \sim 10^{10}$ to $10^{11}$ GeV. Although any observationally viable spectral index can be obtained, the model does predict a distinctive spectral shape.

Search-based 3D Planning and Trajectory Optimization for Safe Micro Aerial Vehicle Flight Under Sensor Visibility Constraints

description: Safe navigation of Micro Aerial Vehicles (MAVs) requires not only obstacle-free flight paths according to a static environment map, but also the perception of and reaction to previously unknown and dynamic objects. This implies that the onboard sensors cover the current flight direction. Due to the limited payload of MAVs, full sensor coverage of the environment has to be traded off with flight time. Thus, often only a part of the environment is covered. We present a combined allocentric complete planning and trajectory optimization approach taking these sensor visibility constraints into account. The optimized trajectories yield flight paths within the apex angle of a Velodyne Puck Lite 3D laser scanner enabling low-level collision avoidance to perceive obstacles in the flight direction. Furthermore, the optimized trajectories take the flight dynamics into account and contain the velocities and accelerations along the path. We evaluate our approach with a DJI Matrice 600 MAV and in simulation employing hardware-in-the-loop.

description: We investigate the mechanism of formation of supermixed soliton-like states in bosonic binary mixtures loaded in ring lattices. We evidence the presence of a common pathway which, irrespective of the number of lattice sites and upon variation of the interspecies attraction, leads the system from a mixed and delocalized phase to a supermixed and localized one, passing through an intermediate phase where the supermixed soliton progressively emerges. The degrees of mixing, localization and quantum correlation of the two condensed species, quantified by means of suitable indicators commonly used in Statistical Thermodynamics and Quantum Information Theory, allow one to reconstruct a bi-dimensional mixing-supermixing phase diagram featuring two characteristic critical lines. Our analysis is developed both within a semiclassical approach capable of capturing the essential features of the two-step mixing-demixing transition and with a fully-quantum approach.

description: Closure and reclamation of waste rock piles using engineered cover systems and water treatment of seepage is a common technique for management of acid rock drainage/metal leaching (ARD/ML) to mitigate adverse impacts to the receiving environment. Linking cover system performance (i.e. net percolation and/or oxygen ingress) to impacts to the receiving environment provides a rational basis for cover system design criteria. Two general models are used in the mining industry to predict long-term seepage and closure costs. One model assumes that loading of contaminants to the environment will remain unchanged under reduced flux rates (net percolation) where contaminant concentrations increase proportionally as a function of decreasing flow; the other assumes that a reduction in the flux rate will result in decreased contaminant loads for constant contaminant concentrations in flow. Both models will have a transition point at which reduced loading to the receiving environment will occur as the flux decreases. Enterprise Cape Breton Corporation implemented a program for the closure of historic coal mines located near Sydney, Nova Scotia, Canada, with Public Works and Government Services Canada providing project management. The Victoria Junction waste rock pile was reclaimed with an engineered cover system comprising a 60 mil HDPE geomembrane, a granular drainage layer and an overlying growth medium. It was estimated following closure that active treatment of seepage waters impacted by ARD/ML would be required for ~20 years before passive treatment systems could be established; however, this has occurred within seven years with significant cost savings realised. Reclamation of the site reduced the risk of potential loading under various failure scenarios. An acidity mass balance was used to provide an understanding of past (uncovered waste rock pile and active treatment), current (covered waste rock pile and passive treatment) and long-term (100 years) loading under progressive changes to water collection and treatment activities. The acidity mass balance will serve to inform management decisions in ongoing closure planning. The case study presented here demonstrates that it is possible to eliminate the need for active treatment of seepage for legacy sites.

urn:lsid:zoobank.org:act: D8D6888A-CDA6-4370-9528-8DC8EABA3438
Type species
Luperus flavofemoratus Jacoby, 1888, by present designation.
Diagnosis
In this genus, the genal length is less than the width of the basal antennomere, the antennal fossae are separated from each other by a distance much less than the diameter of each fossa, the base of the pronotum has a fine yet distinct bead, the tarsal claws are bluntly appendiculate, the rectangular lobe at the apex of the male abdomen is much less than half as long as wide, and the aedeagus is symmetrical and lacks a sclerotized covering to the orifice. However, the most remarkable character is the mesal appendage that extends posteriorly from the posterior margin of second abdominal sternite of the male. This appendage is single at the base but separates into two divergent lobes in the distal half.
Etymology
The name of the genus should be treated as a male noun, and it honors Geetha, the mother of the first author.
Remarks
Although male abdominal appendages are present in some other Scelidites (Cornuventer tuberculatus comb. nov., Androlyperus fulvus, some species of Scelida), the morphology is quite different. See Figs 117 and 174 for a habitus illustration and morphological details of Geethaluperus gen. nov. The single described species included in this genus is G. flavofemoratus (Jacoby, 1888) comb. nov. This species is pale brown, except for the antennae and legs. Most recently, it was included in Pseudoluperus, but it was quite out of place there. An undescribed species from Mexico is very similar in color and morphology (including the abdominal appendage), but the eyes are much smaller (in G. flavofemoratus, the width of the head across the eyes if fully twice as great as the interocular distance, and the genal length is less than the diameter of an ommatidium).

description: On the development of the galvanomagnetic amplifier with Bi Justi and Thuy had to overcome some technological difficulties. The greatest one was the large brittleness of the Bi-foils or -wires. However, in the last years Aske and Fitzpatrick have shown that the ductility of Bi can be enlarged by small amounts of some other metals like Ni.
In this paper the authors give a thorough and systematic analysis of the electrical and mechanical properties of Bi-Ni-alloys. After a detailed discussion of the preparation methods metallurgical and X-ray investigations give a first glance into the structure of the alloys with Ni-contents final to 3,5 atomic per cent. Measurements of the magnetoresistance [Delta] [rho]/[rho]0 at room temperature and at the temperatures of liquid nitrogen and liquid hydrogen confirm generally the expectation of a large decrease with increasing Ni-concentration. Nevertheless at 77°K there is in increase in the [Delta] [rho]/[rho]0-values, possibly connected with a substitution mixed crystal of the otherwise unsoluble Ni in the Bi-lattice.
The ductility of the Bi-Ni-alloys is tested with some kind of bend experiment on wires, produced by pressing the material under 120 kp/mm^2 through a nozzle of 1mm diameter. In contradiction to the statements of Aske and Fitzpatrick the ductility is a monotonic decreasing function with increasing Ni-content up to 0,7 weight% Ni, if the pressure form is not warmed up. However, if the production of the wires is realised at 90°C an alloy with 0,15 weight% Ni is more ductile than a specpure Bi-specimen in agreement with Aske and Fitzpatrick. Yet the absolute value of the ductility is lower than that of a pure Bi-wire, manufactured at room temperature. These experiments are further discussed in connection with some preliminary results on wires produced by cooling the nozzle to liquid air temperature.
Summing up from a practical point of view these investigations show that the Bi is more convenient for a galvanomagnetic amplifier when it contains a small amount of Ni and the wire itself is manufactured by cold working below room temperature.

description: Photoluminescence excitation spectroscopy and scanning tunneling spectroscopy are used to study the electronic states in CdSe quantum rods that manifest a transition from a zero dimensional to a one dimensional quantum confined structure. Both optical and tunneling spectra show that the level structure depends primarily on the rod diameter and not on length. With increasing diameter, the band-gap and the excited state level spacings shift to the red. The level structure was assigned using a multi-band effective-mass model, showing a similar dependence on rod dimensions.

Adaptive risk management and lessons learned : post-closure at the "mighty" Sullivan mine

description: The Sullivan mine in Kimberley, British Columbia, operated for almost 100 years and was one of the world’s largest producers of lead, zinc and silver. Environmental and risk management controls were initiated in the 1960s, including construction in 1979 of the world’s first high-density sludge treatment plant for treatment of acid rock drainage (ARD) associated with large impoundments of tailings, waste rock, other process wastes and underground mine workings. Large-scale assessment of surface water and groundwater systems were initiated in the 1990s in combination with the implementation of additional mitigation measures to control ARD-related impacts. The Sullivan mine officially closed in 2001, and comprehensive site investigation and risk assessment results were used to develop an adaptive site-wide risk management plan (RMP) that outlines long-term monitoring requirements for groundwater, surface water, vegetation and aquatic biota, with triggers for incremental assessment and mitigation as necessary. Since closure, predicted improvements in groundwater and surface water quality have been realised; however, in some locations, RMP action levels have been triggered and incremental assessment and mitigation have been required. As an example, action level triggers were reached in surface water at the lower mine yard, where acidic seepage high in metals from shallow groundwater discharges was detected in the adjacent creek. This triggered additional investigation and implementation of interim measures to capture the groundwater as a longer-term solution is being developed. Triggers were also reached in deeper groundwater in the lower mine yard, and monitoring programs have been adapted to these changing conditions. Other challenges have been administrative, resulting from a closure process spanning over a decade and changes to regulatory policies and mine closure requirements during this time. For example, policy changes under the British Columbia Contaminated Sites Regulation (BC CSR) now require protection of aquifers for future drinking water use, which has affected applicable water quality criteria. Soil quality criteria have also changed for a number of exposure pathways following active closure, changing risk assessment assumptions and prompting additional site investigation activities to comply with the criteria under the BC CSR. These evolving physical and administrative conditions, combined with variations in weather and watershed land use, have reinforced the need for closure plans to include appropriate post-closure monitoring, anticipate the potential need to revisit assumptions made during closure planning and set trigger levels for investigating the need to adjust risk management processes.

description: In this paper we consider the problem of controlling a limited number of target nodes of a network. Equivalently, we can see this problem as controlling the target variables of a structured system, where the state variables of the system are associated to the nodes of the network. We deal with this problem from a different point of view as compared to most recent literature. Indeed, instead of considering controllability in the Kalman sense, that is, as the ability to drive the target states to a desired value, we consider the stronger requirement of driving the target variables as time functions. The latter notion is called functional target controllability. We think that restricting the controllability requirement to a limited set of important variables justifies using a more accurate notion of controllability for these variables. Remarkably, the notion of functional controllability allows formulating very simple graphical conditions for target controllability in the spirit of the structural approach to controllability. The functional approach enables us, moreover, to determine the smallest set of steering nodes that need to be actuated to ensure target controllability, where these steering nodes are constrained to belong to a given set. We show that such a smallest set can be found in polynomial time. We are also able to classify the possible actuated variables in terms of their importance with respect to the functional target controllability problem.

description: In the paper we calculate the frequency shift induced on a photon by the interaction with a low density electronic plasma. The technique is the standard perturbation theory of quantum electrodynamics, taking into account the many body character of the plasma. The shift in non relativistic approximation is shown to be blue. Besides the quantum shift also the known classical effects and the correct temperature dependence are obtained. Finally the limits of the approximations used are discussed.

description: Axial-flow pumps and compressors are usually designed without shroudring. Thus, a flow round the blade-tips is possible and can essentially influence the flow-conditions. This paper deals with the problems which arise in connection with this flow round the bladetips. Results of tests on an one-stage axialflow pump with gradually widened tip-clearance are presented, which are compared with the results, that can be found in the literature.
