A Deterministic Theory for Exact Non-Convex Phase Retrieval

description: In this paper, we analyze the non-convex framework of Wirtinger Flow (WF) for phase retrieval and identify a novel sufficient condition for universal exact recovery through the lens of low rank matrix recovery theory. Via a perspective in the lifted domain, we show that the convergence of the WF iterates to a true solution is attained geometrically under a single condition on the lifted forward model. As a result, a deterministic relationship between the accuracy of spectral initialization and the validity of {the regularity condition} is derived. In particular, we determine that a certain concentration property on the spectral matrix must hold uniformly with a sufficiently tight constant. This culminates into a sufficient condition that is equivalent to a restricted isometry-type property over rank-1, positive semi-definite matrices, and amounts to a less stringent requirement on the lifted forward model than those of prominent low-rank-matrix-recovery methods in the literature. We characterize the performance limits of our framework in terms of the tightness of the concentration property via novel bounds on the convergence rate and on the signal-to-noise ratio such that the theoretical guarantees are valid using the spectral initialization at the proper sample complexity.

High-order topological insulators from high-dimensional Chern insulators

description: Topological insulators are a novel state of matter that share a common feature: their spectral bands are associated with a nonlocal integer-valued index, commonly manifesting through quantized bulk phenomena and robust boundary effects. In this work, we demonstrate using dimensional reduction that high-order topological insulators are descendants from a chiral semimetal in higher dimensions. Specifically, we analyze the descendants of an ancestor four-dimensional Chern insulator in the limit where it becomes chiral and show their relation to two-dimensional second-order topological insulators. Correspondingly, the quantization of the charge accumulation at the corners of the 2D descendants is obtained and related to the topological indices -- the 1st and 2nd Chern numbers -- of the ancestor model. Our approach provides a connection between the boundary states of high-order topological insulators and topological pumps -- the latter being dynamical realizations of high-dimensional Chern insulators.

description: There is a close relation between the problems of second layer nucleation in epitaxial crystal growth and chemical surface reactions, such as hydrogen recombination, on interstellar dust grains. In both cases standard rate equation analysis has been found to fail because the process takes place in a confined geometry. Using scaling arguments developed in the context of second layer nucleation, I present a simple derivation of the hydrogen recombination rate for small and large grains. I clarify the reasons for the failure of rate equations for small grains, and point out a logarithmic correction to the reaction rate when the reaction is limited by the desorption of hydrogen atoms (the second order reaction regime).

description: This paper examines the adaptation of dasymetric mapping methodologies to agricultural data, including their testing and transposition, in order to recover the underlying statistical surface (i.e., an approximation of the real distribution of data). A methodology based on the ideas of Gallego and Peedell (2001) and on the binary method is proposed. It has several steps: (i) the exclusion of target zones for which no observations exist (binary method), (ii) the application of an iterative process to define the most precise densities for data distribution, and (iii) the stratification/definition of sub-units with homogenous characteristics if the results of the previous step are not satisfactory, and the subsequent application of step two. // The methodology was applied in the Alentejo region of Portugal, using data from the 1999 Agricultural Census. Several counties are used as source zones. The aim was to generate a distribution of agro-forestry occupations as close as possible to reality. Two lines of analysis were followed: (i) application of the methodology simultaneously to all counties (definition of regional densities), and (ii) application of the methodology separately to the different sub-areas with similar characteristics (definition of sub-regional densities). For an easy application of the methodology, a computer tool was created, which allowed the easy optimization, validation, and exportation of the data into a Geographic Information System (GIS). // The results were validated using several error indicators at the county level, as well as in a sample of parishes. We show that the second variant of the methodology yielded more precise results, and is superior for the types of data available. This method yielded maps in which the distribution of the most relevant agro-forestry occupations is closest to reality.
Exact diagonalization study of double quantum dots in parallel geometry in zero-bandwidth limit

description: Exact eigenstates of the parallel coupled double quantum dots attached to the non-interacting leads taken in zero-bandwidth limit are analytically obtained in each particle and spin sector. The ground state of the half-filled system is identified from a four dimensional subspace of the twenty dimensional Hilbert space for different values of tunable parameters of the system viz. the energy levels of the quantum dots, the interdot tunneling matrix-element, the ondot and interdot Coulomb interactions and quantities like spin-spin correlation between the dots, occupancies of the dots are calculated. In the parameter space of the interdot tunneling matrix-element and ondot Coulomb interaction, the dots exhibit both ferromagnetic and antiferromagnetic correlation. There is a critical dependency of the interdot tunneling matrix-element on the ondot Coulomb interaction which leads to transition from the ferromagnetic correlation to the antiferromagnetic correlation as the interdot tunneling matrix-element is increased. The ferromagnetic and antiferromagnetic correlations also exist in the absence of interdot tunneling matrix-element through indirect exchange via the leads. The interdot Coulomb interaction is found to affect this dependency considerably.

description: Agricultural production estimates have often differentiated and estimated different technologies within a sample of farms. The common approach is to use observable farm characteristics to split the sample into groups and subsequently estimate different functions for each group. Alternatively, unique technologies can be determined by econometric procedures such as latent class models. This paper compares the results of a latent class model with the use of a priori information to split the sample using dairy farm data. Latent class separation appears to be a superior method of separating heterogeneous technologies and suggests that technology differences are multifaceted.

description: The well-quasi-orders (WQO) play an important role in various fields such as Computer Science, Logic or Graph Theory. Since the class of WQOs lacks closure under some important operations, the proof that a certain quasi-order is WQO consists often of proving it enjoys a stronger and more complicated property, namely that of being a better-quasi-order (BQO).
 Several articles contains valuable introductory material to the theory of BQOs. However, a textbook entitled "Introduction to better-quasi-order theory" is yet to be written. Here is an attempt to give a motivated and self-contained introduction to the deep concept defined by Nash-Williams that we would expect to find in such a textbook.

description: The shift graph is defined on the space of infinite subsets of natural numbers by letting two sets be adjacent if one can be obtained from the other by removing its least element. We show that this graph is not a minimum among the graphs of the form $G_{f}$ defined on some Polish space $X$, where two distinct points are adjacent if one can be obtained from the other by a given Borel function $f:X\to X$. This answers the primary outstanding question from \cite{Kechris19991}.

description: We present an optomechanical device designed to allow optical transduction of orbital angular momentum of light. An optically induced twist imparted on the device by light is detected using an integrated cavity optomechanical system based on a nanobeam slot-mode photonic crystal cavity. This device could allow measurement of the orbital angular momentum of light when photons are absorbed by the mechanical element, or detection of the presence of photons when they are scattered into new orbital angular momentum states by a sub-wavelength grating patterned on the device. Such a system allows detection of a $l = 1$ orbital angular momentum field with an average power of $3.9\times10^3$ photons modulated at the mechanical resonance frequency of the device and can be extended to higher order orbital angular momentum states.

description: Superconducting circuits fabricated using the widely used shadow evaporation technique can contain unintended junctions which change their quantum dynamics. We discuss a superconducting flux qubit design that exploits the symmetries of a circuit to protect the qubit from unwanted coupling to the noisy environment, in which the unintended junctions can spoil the quantum coherence. We present a theoretical model based on a recently developed circuit theory for superconducting qubits and calculate relaxation and decoherence times that can be compared with existing experiments. Furthermore, the coupling of the qubit to a circuit resonance (plasmon mode) is explained in terms of the asymmetry of the circuit. Finally, possibilities for prolonging the relaxation and decoherence times of the studied superconducting qubit are proposed on the basis of the obtained results.

To estimate the error term in our asymptotic formula, we prove a bound for sums of Kloosterman sums of half-integral weight that is uniform in every parameter. To establish this estimate we prove a variant of Kuznetsov's formula where the spectral data is restricted to half-integral weight forms in the Kohnen plus space, and we apply Young's hybrid subconvexity estimates for twisted modular $L$-functions.

description: We study the quasi-order of topological embeddability on definable functions between Polish zero-dimensional spaces. We first study the descriptive complexity of this quasi-order restricted to the space of continuous functions. Our main result is the following dichotomy: the embeddability quasi-order restricted to continuous functions from a given compact space to another is either an analytic complete quasi-order or a well-quasi-order. We then turn to the existence of maximal elements with respect to embeddability in a given Baire class. It is proved that the class of continuous functions is the only Baire class to admit a maximal element. We prove that no Baire class admits a maximal element, except for the class of continuous functions which admits a maximum element.

description: GROW Colombia is a four year bioscience research and capacity building project to preserve, restore and manage biodiversity through responsible innovation in Colombia. This multidisciplinary initiative is funded by the UK Government’s Global Challenge Research Fund and involves a wide, international collaboration of academic and civil society partners united in a shared vision to conserve biodiversity, achieve sustainable prosperity and secure lasting peace in Colombia. The project has a strong socioeconomic component led by the University of East Anglia and involving the Earlham Institute, University of Sydney, Humboldt Institute, Natural History Museum, Universidad de Los Andes, Eden Project and the International Centre for Tropical Agriculture (CIAT).
This is the third socio-economics team report in the GROW Colombia project. It focuses on policy response measures to combat biodiversity loss and climate change, while simultaneously stimulating livelihoods and improving wellbeing. The response measures, as part of an overall package of changes including ‘institutional’ change, seek to enable the country to transition towards a bio-economic development path. This low carbon strategy would help the country to meet its 2030 Greenhouse Gases (GHG) emissions reduction target.

description: This research examined variability in grid prices that can occur within a given day or week for a given set of cattle. Data for one day's slaughter from four plants revealed considerable variation in cattle brought to slaughter by cattle feeders. Several sources of variation were found. Base prices varied $2/dressed cwt., or $15/head, whether using plant averages or formulas tied to reported cash-market prices. Prices across grids added another $2-4/cwt. of variation, another $15 to 30/head. Variation in carcass characteristics contributed significantly to the variation in grid pricing, especially discounted characteristics such as Select and Standard carcasses, Yield Grade 4-5 carcasses, light and heavy carcasses, and non-conforming or "out" carcasses.

description: A family of algorithms for time series classification (TSC) involve running a sliding window across each series, discretising the window to form a word, forming a histogram of word counts over the dictionary, then constructing a classifier on the histograms. A recent evaluation of two of this type of algorithm, Bag of Patterns (BOP) and Bag of Symbolic Fourier Approximation Symbols (BOSS) found a significant difference in accuracy between these seemingly similar algorithms. We investigate this phenomenon by deconstructing the classifiers and measuring the relative importance of the four key components between BOP and BOSS. We find that whilst ensembling is a key component for both algorithms, the effect of the other components is mixed and more complex. We conclude that BOSS represents the state of the art for dictionary based TSC. Both BOP and BOSS can be classed as bag of words approaches. These are particularly popular in Computer Vision for tasks such as image classification. Converting approaches from vision requires careful engineering. We adapt three techniques used in Computer Vision for TSC: Scale Invariant Feature Transform; Spatial Pyramids; and Histrogram Intersection. We find that using Spatial Pyramids in conjunction with BOSS (SP) produces a significantly more accurate classifier. SP is significantly more accurate than standard benchmarks and the original BOSS algorithm. It is not significantly worse than the best shapelet based approach, and is only outperformed by HIVE-COTE, an ensemble that includes BOSS as a constituent module.

description: Critical current density (Jc) is one of the major limiting factors for high field applications of iron-based superconductors. Here, we report that Mn-ions are successfully incorporated into nontoxic superconducting (Li,Fe)OHFeSe films. Remarkably, the Jc is significantly enhanced from 0.03 to 0.32 MA/cm^2 under 33 T, and the vortex pinning force density monotonically increases up to 106 GN/m^3, which is the highest record so far among all iron-based superconductors. Our results demonstrate that Mn incorporation is an effective method to optimize the performance of (Li,Fe)OHFeSe films, offering a promising candidate for high-field applications.

description: This study applies to a Bayesian methodology to the oft-examined issue of whether a structural change has occurred in U.S. meat demand. The Bayesian approach allows us several advantages over earlier studies. First, we can estimate the true AIDS model instead of the commonly substituted linear-approximate version. Second, we derive the marginal posterior distribution of the time period in which the structural change occurred. This provides greater insight into whether the data is sharply or mildly informative as to such a structural change. Finally, we can derive posterior density results for the changes in parameters and elasticities across the two regimes. The results show the data to be highly informative with respect to a structural change in meat demand in the fourth quarter of 1975, but less evidence is found for changes in the majority of individual model parameters.

description: We construct models describing interaction between a spin $s$ and a single bosonic mode using a quantum inverse scattering procedure. The boundary conditions are generically twisted by generic matrices with both diagonal and off-diagonal entries. The exact solution is obtained by mapping the transfer matrix of the spin-boson system to an auxiliary problem of a spin-$j$ coupled to the spin-$s$ with general twist of the boundary condition. The corresponding auxiliary transfer matrix is diagonalized by a variation of the method of $Q$-matrices of Baxter. The exact solution of our problem is obtained applying certain large-$j$ limit to $su(2)_j$, transforming it into the bosonic algebra.

description: This study examined the potential reliability of seasonality in intermarket incremental margin calendar crushes, expected margin calendar crushes, and deferred crushes for application in real-time futures trading. Seasonal rolling averages were used to select the expected high (sell) and buy (low) points for out-of-sample trading simulations of four processing spreads: the heating oil crush, the unleaded gasoline crush, the soybean complex crush, and the cattle crush. Results suggest that simply buy (sell) and holding trading strategies based on historical seasonality do not generally produce positive profits that re significantly different from zero. Results indicate that of the twelve crush combinations examined, only the incremental cattle and the May deferred cattle crushes exhibited statistically significant profits. Furthermore, results suggest that although seasonal recurring patterns allude to profit opportunities, these opportunities erode quickly due to rolling and trading transactions costs.

description: From the autonomous car driving to medical diagnosis, the requirement of the task of image segmentation is everywhere. Segmentation of an image is one of the indispensable tasks in computer vision. This task is comparatively complicated than other vision tasks as it needs low-level spatial information. Basically, image segmentation can be of two types: semantic segmentation and instance segmentation. The combined version of these two basic tasks is known as panoptic segmentation. In the recent era, the success of deep convolutional neural networks (CNN) has influenced the field of segmentation greatly and gave us various successful models to date. In this survey, we are going to take a glance at the evolution of both semantic and instance segmentation work based on CNN. We have also specified comparative architectural details of some state-of-the-art models and discuss their training details to present a lucid understanding of hyper-parameter tuning of those models. We have also drawn a comparison among the performance of those models on different datasets. Lastly, we have given a glimpse of some state-of-the-art panoptic segmentation models.

description: Aronson's sequence 1, 4, 11, 16, ... is defined by the English sentence ``t is the first, fourth, eleventh, sixteenth, ... letter of this sentence.'' This paper introduces some numerical analogues, such as: a(n) is taken to be the smallest positive integer greater than a(n-1) which is consistent with the condition ``n is a member of the sequence if and only if a(n) is odd.'' This sequence can also be characterized by its ``square'', the sequence a^(2)(n) = a(a(n)), which equals 2n+3 for n >= 1. There are many generalizations of this sequence, some of which are new, while others throw new light on previously known sequences.

description: This study examines the relationship between the futures price at the time of production/placement decision and the price at the time of the harvest/marketing decision for the storable commodities corn, soybeans, and wheat and non-storable commodities, fed cattle and hogs. Additionally, a model is employed to identify determinants of the error associated with the use of a springtime futures price as a forecast for the harvest period price of corn, soybeans, and wheat. Results indicate that the springtime futures price is a biased forecast for the harvest price of corn, soybeans, and wheat. However, the price forecast is an unbiased estimate for the price of cattle and hogs during the marketing period. The predictability of supply and demand estimates and the time period of the price forecast for the storable commodities are significantly related to the error associated with the forecast.

Holography and the Higgs branch of N=2 SYM theories

description: We present a proposal for the description of the Higgs branch of four-dimensional N=2 supersymmetric Yang-Mills theories in the context of the AdS/CFT correspondence. We focus on a finite Sp(N) N=2 theory arising as dual of a configuration of N D3-branes in the vicinity of four D7-branes and an orientifold 7-plane in type I' string theory. The field theory contains hypermultiplets in the second rank anti-symmetric and in the fundamental representations. The Higgs branch has a dual description in terms of gauge field configurations with non-zero instanton number on the world-volume of the D7-branes. In this setting the non-renormalisation of the metric on the Higgs branch implies constraints on the alpha' corrections to the D7-brane effective action, including couplings to the curvature and five-form field strength. In the second part of the paper we discuss non-renormalisation properties of BPS Wilson lines, which are closely related to the physics of the Higgs branch. Using a formulation of the four-dimensional N=2 theory in terms of a three-dimensional N=2 superspace we show that the expectation value of certain Wilson-line operators with hypermultiplets at the end points is independent of the length and thus coincides with the expectation value of the local operators parametrising the Higgs branch.

description: Diabetic Retinopathy (DR) is a leading cause of vision loss around the world. To help diagnose it, numerous cutting-edge works have built powerful deep neural networks (DNNs) to automatically grade DR via retinal fundus images (RFIs). However, RFIs are commonly affected by camera exposure issues that may lead to incorrect grades. The mis-graded results can potentially pose high risks to an aggravation of the condition. In this paper, we study this problem from the viewpoint of adversarial attacks. We identify and introduce a novel solution to an entirely new task, termed as adversarial exposure attack, which is able to produce natural exposure images and mislead the state-of-the-art DNNs. We validate our proposed method on a real-world public DR dataset with three DNNs, e.g., ResNet50, MobileNet, and EfficientNet, demonstrating that our method achieves high image quality and success rate in transferring the attacks. Our method reveals the potential threats to DNN-based automatic DR grading and would benefit the development of exposure-robust DR grading methods in the future.

description: This study is a simulation that tests whether Kansas wheat, corn, milo (grain sorghum) and soybean producers could have used deferred futures plus historical basis cash price expectations to profitably guide post-harvest unhedged and hedged grain storage decisions from 1985 through 1997. The signaled storage decision is compared to a representative Kansas producer whose crop sales mimic average Kansas marketings each year. Twenty-three grain price locations are examined. The simulation resulted in an 11-cent per bushel annual increase in grain storage profits for wheat producers, 27 cents for soybeans, -17 cents for corn, and -20 cents for milo; but storage profit differences varied substantially across locations. Inferences for random Kansas cash price locations were generally robust to alternative assumptions about interest rates or storage costs, but sensitive to assumptions of model starting dates and basis specification. Hedging tended to decrease risk but not impact profitability. Few results were consistent across the numerous scenarios involving different crops, locations, and specifications for futures-plus-basis post-harvest grain storage signaling models; thus, this research does not reject cash market efficiency.

description: Despite the presence of food miles labels and carbon labels on the market for many years, relatively little data is available on how consumers respond to these labels. It is one thing to show people saying in surveys they will use carbon labels, and quite another to have evidence of people actually using them. Carbon labels could be complicated to develop and implement fairly, with significant burdens on producers, especially in developing countries. If the only problem that a carbon label solves is relieving the bad conscience of rich western consumers, then they will be a disaster. Tackling climate change is too urgent to waste time and resources on anything that may prove to be a sideshow.
