The Relation between Wavefunction and 3D Space Implies Many Worlds with Local Beables and Probabilities

description: We show that the quantum wavefunctional can be seen as a set of classical fields on the 3D space aggregated by a measure. We obtain a complete description of the wavefunctional in terms of classical local beables. With this correspondence, classical explanations of the macro level and of probabilities transfer almost directly to the quantum. A key difference is that, in quantum theory, the classical states coexist in parallel, so the probabilities come from self-location uncertainty. We show that these states are distributed according to the Born rule. The coexistence of classical states implies that there are many worlds, even if we assume the collapse postulate. This leads automatically to a new version of the many-worlds interpretation in which the major objections are addressed naturally. We show that background-free quantum gravity provides additional support for this proposal and suggests why branching happens toward the future.

description: Several new combinatorial descriptions of closed 4-manifolds have recently been introduced in the study of smooth maps from 4-manifolds to surfaces. These descriptions consist of simple closed curves in a closed, orientable surface and these curves appear as so called vanishing sets of corresponding maps. In the present paper we focus on homotopies canceling pairs of cusps so called cusp merges. We first discuss the classification problem of such homotopies, showing that there is a one-to-one correspondence between the set of homotopy classes of cusp merges canceling a given pair of cusps and the set of homotopy classes of suitably decorated curves between the cusps. Using our classification, we further give a complete description of the behavior of vanishing sets under cusp merges in terms of mapping class groups of surfaces. As an application, we discuss the uniqueness of surface diagrams, which are combinatorial descriptions of 4-manifolds due to Williams, and give new examples of surface diagrams related with Lefschetz fibrations and Heegaard diagrams.

description: Primordial magnetic fields (PMF) can create polarization $B$-modes in the cosmic microwave background (CMB) through Faraday rotation (FR), leading to non-trivial 2-point and 4-point correlators of the CMB temperature and polarization. We discuss the detectability of primordial magnetic fields using different correlators and evaluate their relative merits. We have fully accounted for the contamination by weak lensing, which contributes to the variance, but whose contribution to the 4-point correlations is orthogonal to that of FR. We show that a Planck-like experiment can detect scale-invariant PMF of nG strength using the FR diagnostic at 90GHz, while realistic future experiments at the same frequency can detect 10^{-10} G. Utilizing multiple frequencies will improve on these prospects, making FR of CMB a powerful probe of scale-invariant PMF.

description: Upon introducing charge carriers into the copper-oxygen sheets of the enigmatic lamellar cuprates the ground state evolves from an insulator into a superconductor, and eventually into a seemingly conventional metal (a Fermi liquid). Much has remained elusive about the nature of this evolution and about the peculiar metallic state at intermediate hole-carrier concentrations (p). The planar resistivity of this unconventional metal exhibits a linear temperature dependence (ρ$\propto$ T) that is disrupted upon cooling toward the superconducting state by the opening of a partial gap (the pseudogap) on the Fermi surface. Here we first demonstrate for the quintessential compound HgBa$_2$CuO$_{4+δ}$ a dramatic switch from linear to purely quadratic (Fermi-liquid-like, ρ$\propto$ T$^2$) resistive behavior in the pseudogap regime. Despite the considerable variation in crystal structures and disorder among different compounds, our result together with prior work gives new insight into the p-T phase diagram and reveals the fundamental resistance per copper-oxygen sheet in both linear (ρ_S = A_{1S} T) and quadratic (ρ_S = A_{2S} T$^2$) regimes, with A_{1S} $\propto$ A_{2S} $\propto$ 1/p. Theoretical models can now be benchmarked against this remarkably simple universal behavior. Deviations from this underlying behavior can be expected to lead to new insights into the non-universal features exhibited by certain compounds.

description: We study the competition between ferromagnetic and spin glass phases using a system of coupled infinite-range Ising and Sherrington-Kirkpatrick models. We obtain the replica-symmetric solution for the free energy of this system in terms of magnetization and Edwards-Anderson order parameters in both subsystems. Using these order parameters we are able to identify different phases in the system and determine which phase is dominant for different strengths of the coupling between two subsystems. We observe that both subsystems are in the same phase although with different order parameters. The phase boundary between paramagnetic-ferromagnetic and paramagnetic-spin glass phases is more or less similar to that in the Sherrington-Kirkpatrick phase diagram. But the boundary between ferromagnetic-spin glass phases becomes qualitatively different as the coupling between the two subsystems changes. Remarkably, for intermediate values of the coupling, this phase boundary is such that there could be a reentrant transition between spin glass and ferromagnetic phases by increasing the temperature. We found that for some range of the coupling, the second order transition between these phases turns into first order at a tricritical point. Further, we carry out the stability analysis by considering deviations from the replica symmetric solution.

description: The homotopy theory of small functors is a useful tool for studying various questions in homotopy theory. In this paper, we develop the homotopy theory of small functors from spectra to spectra, and study its interplay with Spanier-Whitehead duality and enriched representability in the dual category of spectra. We note that the Spanier-Whitehead duality functor $D\colon \mathrm{Sp}\rightarrow \mathrm{Sp}^{\mathrm{op}}$ factors through the category of small functors from spectra to spectra and construct a new model structure on the category of small functors, which is Quillen equivalent to $\mathrm{Sp}^{\mathrm{op}}$. In this new framework for the Spanier-Whitehead duality, $\mathrm{Sp}$ and $\mathrm{Sp}^{\mathrm{op}}$ are full subcategories of the category of small functors and dualization becomes just a fibrant replacement in our new model structure.

Conditions for a Monotonic Channel Capacity

Year: 2012
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Motivated by results in optical communications, where the performance can degrade dramatically if the transmit power is sufficiently increased, the channel capacity is characterized for various kinds of memoryless vector channels. It is proved that for all static point-to-point channels, the channel capacity is a nondecreasing function of power. As a consequence, maximizing the mutual information over all input distributions with a certain power is for such channels equivalent to maximizing it over the larger set of input distributions with upperbounded power. For interference channels such as optical wavelength-division multiplexing systems, the primary channel capacity is always nondecreasing with power if all interferers transmit with identical distributions as the primary user. Also, if all input distributions in an interference channel are optimized jointly, then the achievable sum-rate capacity is again nondecreasing. The results generalizes to the channel capacity as a function of a wide class of costs, not only power.

description: Excerpt from the report: This report describes a study conducted from January through July 1968 to find ways of preventing deterioration of packaged fresh kale, and of prolonging its storage and shelf life. Research for the study was directed toward a series of tests in which sorted and unsorted fresh whole kale leaves and fresh packaged whole kale leaves were given various prestorage treatments and then subjected to different storage and holding environments for various periods of time. Throughout the tests, emphasis was placed on finding better storage and holding methods for washed and for unwashed fresh kale stored in wood shipping and storage containers, or packaged as consumer units in 10-ounce cellophane bags.

description: We propose an alternative definition of an N-dimensional coined quantum walk by generalizing a recent proposal [Di Franco et al., Phys. Rev. Lett. 106, 080502 (2011)]. This N-dimensional alternate quantum walk, AQW_N, in contrast with the standard definition of the N-dimensional quantum walk, QW_N, requires only a coin-qubit. We discuss the quantum diffusion properties of AQW_2 and AQW_3 by analyzing their dispersion relations that reveal, in particular, the existence of diabolical points. This allows us to highlight interesting similarities with other well known physical phenomena. We also demonstrate that AQW_3 generates genuine multipartite entanglement. Finally we discuss the implementability of AQW_N.

description: The celebrated Smith-Minkowski-Siegel mass formula expresses the mass of a quadratic lattice (L, Q) as a product of local factors, called the local densities of (L,Q). This mass formula is an essential tool for the classification of integral quadratic lattices. In this paper, we will describe the local density formula explicitly, by constructing a smooth integral group scheme model for an appropriate orthogonal group. Our method works for any unramified finite extension of Q_2. Therefore, we give a long awaited proof for the local density formula of Conway and Sloane and discover its generalization to unramified finite extensions of Q_2. As an example, we give the mass formula for the integral quadratic form Q_n(x_1, ..., x_n)=x_1^2 + ... + x_n^2 associated to a number field k which is totally real and such that the ideal (2) is unramified over k.

description: Report Summary: Hot-water treatments to reduce the development of spoilage of cranberries during or after storage were tested for 3 years. Treating berries before storage in 110°, 115°, 120°, or 125° F. water for 20, 10, 5, and 2 1/2 minutes, respectively, reduced the number of pathogens that survived, but did not always reduce the total spoilage of the berries. Generally the hot-water treatments reduced the development of spoilage better in early-harvested than in late-harvested berries. Hot-water treatments apparently increased the amount of physiological breakdown in late-harvested berries. The early-harvested berries developed less spoilage than the late-harvested ones.

description: This tutorial deals with the model development of the piezoresistance of Single Walled Carbon Nanotubes (SWCNTs) as components at system level design. The framework VHDL-AMS (virtual hardware description language) is used for implementation and simulation. It is based on compact models to describe the components performing heterogeneous functions. The mechanical and electronical compact submodels of SWCNTs are based on the analytical models and lumped element models.

The tutorial presents important aspects in developing these system models and the necessary parameters in creating those models. The developed models can be used for the design of SWCNT based mechanical sensors and for co-simulation with any other system environment or complex electronic circuit.

Our main result says that if $E"_m - E'_m \le \ve \exp(-κ_0 |m|)$ for all $m \in \zv$, with $\ve$ being small enough, depending on $κ_0 > 0$ and the frequency vector involved, then the Fourier coefficients of $V$ obey $|c(m)| \le \ve^{1/2} \exp(-\frac{κ_0}{2} |m|)$ for all $m \in \zv$. On the other hand we prove that if $|c(m)| \le \ve \exp(-κ_0 |m|)$ with $\ve$ being small enough, depending on $κ_0 > 0$ and the frequency vector involved, then $E"_m - E'_m \le 2 \ve \exp(-\frac{κ_0}{2} |m|)$.

description: Excerpts from the report: Today mechanically refrigerated railcars are being constructed tighter than previously to improve the efficiency of the refrigeration and to facilitate the deliberate modification of the car atmosphere for those shippers desiring this service. Commodities with high respiration rates, such as lettuce, cause a modification of the atmosphere in these tightly constructed cars. The carbon dioxide levels tend to build up and oxygen (02) levels, to be reduced. Because of the relationship observed between C02 levels and brown stain, and because of the absence of continuous C02 records during transit in the new railcars, a 10-car test shipment of lettuce was made from Salinas, Calif., to the New York marketing area during July and August in 1970. Carbon dioxide and O2 levels in the cars were measured both enroute and at destination, and the market quality of the lettuce was evaluated at destination.

description: Recent works have demonstrated that deep neural networks (DNNs) are highly vulnerable to adversarial attacks. To defend against adversarial attacks, many defense strategies have been proposed, among which adversarial training has been demonstrated to be the most effective strategy. However, it has been known that adversarial training sometimes hurts natural accuracy. Then, many works focus on optimizing model parameters to handle the problem. Different from the previous approaches, in this paper, we propose a new approach to improve the adversarial robustness by using an external signal rather than model parameters. In the proposed method, a well-optimized universal external signal called a booster signal is injected into the outside of the image which does not overlap with the original content. Then, it boosts both adversarial robustness and natural accuracy. The booster signal is optimized in parallel to model parameters step by step collaboratively. Experimental results show that the booster signal can improve both the natural and robust accuracies over the recent state-of-the-art adversarial training methods. Also, optimizing the booster signal is general and flexible enough to be adopted on any existing adversarial training methods.

description: Metric learning has attracted a lot of interest over the last decade, but the generalization ability of such methods has not been thoroughly studied. In this paper, we introduce an adaptation of the notion of algorithmic robustness (previously introduced by Xu and Mannor) that can be used to derive generalization bounds for metric learning. We further show that a weak notion of robustness is in fact a necessary and sufficient condition for a metric learning algorithm to generalize. To illustrate the applicability of the proposed framework, we derive generalization results for a large family of existing metric learning algorithms, including some sparse formulations that are not covered by previous results.

description: Deliberate and unintentional radio transmissions from Earth propagate into space. These transmissions could be detected by extraterrestrial watchers over interstellar distances. Here, we analyze the harms and benefits of deliberate and unintentional transmissions relevant to Earth and humanity. Comparing the magnitude of deliberate radio broadcasts intended for messaging to extraterrestrial intelligence (METI) with the background radio spectrum of Earth, we find that METI attempts to date have much lower detectability than emissions from current radio communication technologies on Earth. METI broadcasts are usually transient and several orders of magnitude less powerful than other terrestrial sources such as astronomical and military radars, which provide the strongest detectable signals. The benefits of radio communication on Earth likely outweigh the potential harms of detection by extraterrestrial watchers; however, the uncertainty regarding the outcome of contact with extraterrestrial beings creates difficulty in assessing whether or not to engage in long-term and large-scale METI.

description: We investigate within the Darmois-Israel thin shell formalism the match of neutral and asymptotically flat, slowly rotating spacetimes (up to the second order in the rotation parameter) when their boundaries are dynamic. It has several important applications in general relativistic systems, such as black holes and neutron stars, which we exemplify. We mostly focus on stability aspects of slowly rotating thin shells in equilibrium and surface degrees of freedom on the hypersurfaces splitting the matched slowly rotating spacetimes, e.g., surface energy density and surface tension. We show that the stability upon perturbations in the spherically symmetric case automatically implies stability in the slow rotation case. In addition, we show that when matching slowly rotating Kerr spacetimes through thin shells in equilibrium, surface degrees of freedom can decrease compared to their Schwarzschild counterparts, meaning that energy conditions could be weakened. Frame-dragging aspects of the match of slowly rotating spacetimes are also briefly discussed.

description: Laser-driven plasma wakefield accelerators provide accelerating electric fields orders of magnitude higher compared to conventional accelerators. Towards the generation of quasi-monoenergetic, multi-gigaelectronvolt electron beams, a precise control in the femtosecond time scale of the injection of electrons is needed.

In this diploma thesis a new computational method to study external injection of electrons in laser-wakefield accelerators was derived. By loading a relativistic, charged particle bunch with arbitrary distribution in energy, space and time new ways to study the properties of wakefield accelerated electrons are possible.

Furthermore, the proposed scheme was implemented together with an advanced field solver to suppress numerical Cherenkov noise in the open source Particle-in-Cell code PIConGPU as they are critical to reduce numerical uncertainties in relativistic simulations.

Powered with modern compute hardware (GPUs) it is now possible to reach a new quality of predictive simulations, running repeated simulations in a few hours compared to weeks as with today's legacy codes. New parallel algorithms to study the evolution of the acceleration process have been implemented such as the in-situ calculation of a two-dimensional phase space distribution. Providing live feedback from simulations introduces a paradigm change towards interactive numerical studies and dramatically reduces the amount of data for post-processing.

Finally, numerical studies have been carried out benefiting from the new methods and implementations such as an extended down-ramp triggered self-injection scenario suitable for the reproducible generation of tunable electron bunches.

description: Let k be an algebraically closed field of characteristic zero. In this paper we prove that fusion categories of Frobenius-Perron dimensions 84 and 90 are of Frobenius type. Combining this with previous results in the literature, we obtain that every weakly integral fusion category of Frobenius-Perron dimension less than 120 is of Frobenius type.

A Simple Camera Cmos Sensor Noise Model
Creators: name: de Lama, Oscar
Publisher: name: Zenodo

Subjects: noise, digital image, camera sensor, model

description: There are different sources of information, like the Internet, depicting the behavior and noise characterization in a raw image from a digital CMOS sensor. In those posts, it is said the shot noise and the PRNU noise are additive components of the raw image variance, where —with respect to the signal— the first one has a linear relationship, while the second has a quadratic one. However, there is not an explanation about how this behavior arises. This paper fills that gap, proposing a simple model based on known CMOS sensor characteristics and shows how this model explains the aforementioned noise profile.

description: Recently, it has been widely known that deep neural networks are highly vulnerable and easily broken by adversarial attacks. To mitigate the adversarial vulnerability, many defense algorithms have been proposed. Recently, to improve adversarial robustness, many works try to enhance feature representation by imposing more direct supervision on the discriminative feature. However, existing approaches lack an understanding of learning adversarially robust feature representation. In this paper, we propose a novel training framework called Robust Proxy Learning. In the proposed method, the model explicitly learns robust feature representations with robust proxies. To this end, firstly, we demonstrate that we can generate class-representative robust features by adding class-wise robust perturbations. Then, we use the class representative features as robust proxies. With the class-wise robust features, the model explicitly learns adversarially robust features through the proposed robust proxy learning framework. Through extensive experiments, we verify that we can manually generate robust features, and our proposed learning framework could increase the robustness of the DNNs.

Distinguishability, Ensemble Steering, and the No-Signaling Principle
Creators: name: Bae, Joonwoo
Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider a fundamental operational task, distinguishing systems in different states, in the framework of generalized probabilistic theories and provide a general formalism of minimum-error discrimination of states in convex optimization. With the formalism established, we show that the distinguishability is generally a global property assigned to the ensemble of given states rather than other details of a given state space or pairwise relations of given states. Then, we consider bipartite systems where ensemble steering is possible, and show that show that with two operational tasks, ensemble steering and the no-signaling condition, the distinguishability is tightly determined. The result is independent to the structure of the state space. This concludes that the distinguishability is generally determined by the compatibility between two tasks, ensemble steering on states and the non-signaling principle on probability distributions of outcomes.

description: Fluidized beds are suspensions of grains by ascending fluids in tubes, and are commonly used in industry given their high rates of mass and heat transfers between the solids and fluid. Although usually employed in large scales (tube diameter of the order of the meter), fluidized beds have a great potential in much smaller scales (order of the millimeter) for processes involving powder and fluids. Of particular interest is the pharmaceutical industry, which can take advantage of mm-scale fluidized beds for promoting diffusion of species, classifying grains, or peeling individual particles. This paper reports experiments with a mm-scale gas-solid fluidized bed, which consisted of 0.5-mm-diameter glass particles suspended by an air flow in a 3-mm-ID glass tube. We filmed the bed with a high-speed camera and processed the images with a numerical code for tracking both the entire bed and individual particles. We found that instabilities in the form of alternating high- and low-compactness regions (known respectively as plugs and bubbles) appear in the bed, and that the fluctuating energy of particles (known as granular temperature) is relatively low within plugs. Therefore, mm-scale beds have much reduced agitation and transfer rates when compared to their m-scale counterparts. We show also that increasing the flow velocity does not avoid the appearance of plugs, though the granular temperature increases, mitigating the problem. Our results shed light on detailed mechanisms taking place within the miniaturized bed, providing insights for chemical and pharmaceutical processes involving powders.

Quantum protocols for the millionaire problem with a third party are trivial

Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Recently there were many quantum protocols devoted to solve the millionaire problem and private comparison problem by adding a semi-honest third party. They all require complicated quantum methods, while still leak a non-trivial amount of information to at least one of the parties. But it will be shown here that once the third party is introduced, there are very simple protocols which require quantum key distribution as the only quantum resource, and the amount of information leaked can be made arbitrarily small. Furthermore, even a dishonest third party cannot spoil the protocols. Thus our solutions surpass all existing protocols on both feasibility and security.
description: The protocol is further improved so that it remains secure even if the third party is distrustful

description: In this Letter, we derive an entropic Einstein-Podolsky-Rosen (EPR) steering inequality for continuous variable (CV) systems using only experimentally measured discrete probability distributions and details of the measurement apparatus. We use this inequality to witness EPR steering between the positions and momenta of photon pairs generated in spontaneous parametric downconversion (SPDC). We examine the asymmetry between parties in this inequality, and show that this asymmetry can be used to reduce the technical requirements of experimental setups intended to demonstrate the EPR paradox. Furthermore, we develop a more stringent steering inequality that is symmetric between parties, and use it to show that the downconverted photon pairs also exhibit symmetric EPR steering.

description: Excerpts from the report: The Chinese Gooseberry (Actinidia chinensis Planch), also known as Kiwi fruit, was brought to California about 45 years ago by research workers at the U.S. Plant Introduction Station at Chico. In 1961, the plant was released by that station as a potential new fruit crop for the United States. Since that time, small, but expanding, plantings of the vine have been made in suitable growing areas of California. Little work has been done on the postharvest handling of Chinese gooseberries in the United States. Because of the potential commercial importance of the crop, more information was needed on the physiological changes that occur in the fruit during storage and ripening, on the optimum dates for picking the fruit for immediate marketing or for storage, and on other factors affecting the postharvest quality of the fruit.

description: The accurate detection of suspicious regions in medical images is an error-prone and time-consuming process required by many routinely performed diagnostic procedures. To support clinicians during this difficult task, several automated solutions were proposed relying on complex methods with many hyperparameters. In this study, we investigate the feasibility of DEtection TRansformer (DETR) models for volumetric medical object detection. In contrast to previous works, these models directly predict a set of objects without relying on the design of anchors or manual heuristics such as non-maximum-suppression to detect objects. We show by conducting extensive experiments with three models, namely DETR, Conditional DETR, and DINO DETR on four data sets (CADA, RibFrac, KiTS19, and LIDC) that these set prediction models can perform on par with or even better than currently existing methods. DINO DETR, the best-performing model in our experiments demonstrates this by outperforming a strong anchor-based one-stage detector, Retina U-Net, on three out of four data sets.

description: We show that the maximum likelihood degree of a smooth very affine variety is equal to the signed topological Euler characteristic. This generalizes Orlik and Terao's solution to Varchenko's conjecture on complements of hyperplane arrangements to smooth very affine varieties. For very affine varieties satisfying a genericity condition at infinity, the result is further strengthened to relate the variety of critical points to the Chern-Schwartz-MacPherson class. The strengthened version recovers the geometric deletion-restriction formula of Denham et al. for arrangement complements, and generalizes Kouchnirenko's theorem on the Newton polytope for nondegenerate hypersurfaces.
