Photons Do Collapse In the Retina Not in the Brain Cortex: Evidence from Visual Illusions

Publisher: name: arXiv
Year: 2002
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: While looking for evidence of quantum coherent states within the brain, many quantum mind advocates proposed experiments based on the assumption that the coherent state of a photon entering the visual system could somehow be preserved through the neural processing, or in other words they suppose that photons collapse not in the retina, but in the brain cortex. In this paper we show that photons do collapse within the retina and subsequent processing of information at the level of neural membranes proceeds. Moreover, we explicitly stress on the fact that due to existent amplification of the signal produced by each photon, a basic quantum mechanical theorem forbids the photon state to be teleported from the retina to the brain cortex. The changes of the membrane potential of the neurons in the primary visual cortex are shown to be relevant to inputting visual sensory information that is already processed and is not identical to the visual image entering in the retina. A striking evidence for the existent processing of the incoming visual information by the retina is provided by visual illusions resulting from the lateral inhibition mechanism.

description: Missing data imputation (MDI) is a fundamental problem in many scientific disciplines. Popular methods for MDI use global statistics computed from the entire data set (e.g., the feature-wise medians), or build predictive models operating independently on every instance. In this paper we propose a more general framework for MDI, leveraging recent work in the field of graph neural networks (GNNs). We formulate the MDI task in terms of a graph denoising autoencoder, where each edge of the graph encodes the similarity between two patterns. A GNN encoder learns to build intermediate representations for each example by interleaving classical projection layers and locally combining information between neighbors, while another decoding GNN learns to reconstruct the full imputed data set from this intermediate embedding. In order to speed-up training and improve the performance, we use a combination of multiple losses, including an adversarial loss implemented with the Wasserstein metric and a gradient penalty. We also explore a few extensions to the basic architecture involving the use of residual connections between layers, and of global statistics computed from the data set to improve the accuracy. On a large experimental evaluation, we show that our method robustly outperforms state-of-the-art approaches for MDI, especially for large percentages of missing values.

description: Collective behavior is studied in globally coupled maps with distributed nonlinearity. It is shown that the heterogeneity enhances regularity in the collective dynamics. Low-dimensional quasiperiodic motion is often found for the mean-field, even if each element shows chaotic dynamics. The mechanism of this order is due to the formation of an internal bifurcation structure, and the self-consistent dynamics between the structures and the mean-field.

description: The recent years have seen several proposals aimed at placing the revision of logic programs within the belief change frameworks established for classical logic. A crucial challenge of this task lies in the nonmonotonicity of standard logic programming semantics. Existing approaches have thus used the monotonic characterisation via strong equivalence models to develop semantic revision operators, which however neglect any syntactic information. In this thesis, we bridge the gap between semantic and syntactic techniques by adapting three dierent types of constructions from classic belief change. Not only do they allow us to dene new model-based revision operators that preserve the structure of the programs involved, but they also facilitate a natural denition of contraction operators for logic programs. In particular, we introduce partial meet revision and contraction operators, ensconcement revision and contraction operators, and entrenchment revision and contraction operators for logic programs. We present a new translation of the AGM and belief base revision and contraction postulates to logic programs that is closer to the original formulation than existing translations.
Essays on Price Adjustment and Imperfect Information

Publisher: name: Columbia University
Year: 2012
Subjects: Economics

description: Understanding how firms set prices is a key step towards settling classic debates in economics regarding the sources of nominal price rigidities, the mechanisms through which disturbances are transmitted within and across countries, and the effectiveness of monetary policy in dampening business cycle fluctuations. This dissertation examines patterns of price adjustment at the firm level, both empirically and theoretically. The first chapter studies pricing patterns in US grocery store data. Using a novel empirical method, I identify changes in the distribution of product-level prices over time. These changes typically occur every seven months and mark the transition to new pricing regimes. Inside regimes, prices alternate among a small set of prices with high frequency. This evidence motivates a theory of price setting in which firms respond to shocks using multiple-price policies that are simple enough to only specify a small number of prices, and that are updated only on discrete occasions. The second chapter presents a theory of costly information that generates such simple, sticky  policies. In order to economize on the costs of acquiring information, the firm designs a pricing policy that is a noisy, coarse representation of market conditions. Moreover, it updates this policy infrequently, based on imprecise signals about the state of the economy. Despite the high volatility of observed prices, the firm responds imperfectly to changes in market conditions. The third chapter, co-authored with Ryan Chahrour, addresses the patterns of adjustment in international relative prices. We develop a two-country model in which retailers have imperfect information and search for producers operating in different regions in the two countries. We demonstrate that frictions at the regional level within countries generate dispersion in international relative prices in the absence of additional frictions at the national border.

Besides a confirmation of the hypothesis predictions the results suggest the validity of the hypothesis in the much wider context in which, as the forcing strength grows, the attractor ceases to be an Anosov system and becomes an Axiom A attractor. A first test of the new predictions is also attempted.

description: It was proposed that erosion of subsea ridges on the Hikurangi margin may be linked to a fluctuating level of the top of gas hydrate stability in the ocean. Since publication of this hypothesis, three field campaigns were conducted in the study area. Here we summarize relevant results from these cruises. We found that water temperature fluctuations occur at lower frequencies and higher amplitudes than previously thought, making it more likely that temperature changes reach sub-seafloor gas hydrates. Dredge samples encountered numerous consolidated mudstones. We speculate that gas hydrate “freeze-thaw” cycles may lead to dilation of fractures in mudstones due to capillary forces, weakening the seafloor. Ubiquitous gas pockets beneath the ridge may lead to overpressure that may also contribute to seafloor fracturing.

description: Document-grounded dialogue (DGD) uses documents as external knowledge for dialogue generation. Correctly understanding the dialogue context is crucial for selecting knowledge from the document and generating proper responses. In this paper, we propose using a dialogue policy to help the dialogue understanding in DGD. Our dialogue policy consists of two kinds of guiding signals: utterance function and topic transfer intent. The utterance function reflects the purpose and style of an utterance, and the topic transfer intent reflects the topic and content of an utterance. We propose a novel framework exploiting our dialogue policy for two core tasks in DGD, namely knowledge selection (KS) and response generation (RG). The framework consists of two modules: the Policy planner leverages policy-aware dialogue representation to select knowledge and predict the policy of the response; the generator uses policy/knowledge-aware dialogue representation for response generation. Our policy-driven model gets state-of-the-art performance on three public benchmarks and we provide a detailed analysis of the experimental results. Our code/data will be released on GitHub.

description: A source of single photons and quantum entangled photon pairs is a key element in quantum information networks. Here, we demonstrate the electrically driven generation of quantum entangled pairs using a naturally symmetric GaAs quantum dot grown by droplet epitaxy. Coincidence histograms obtained at a temperature of 10 K reveal the generation of quantum entangled pairs that have a fidelity to the Bell pairs of 0.71 +- 0.015, much beyond the classical limit. The quantum nature of the emitted pairs is conserved at temperatures of up to ~65 K, and is essentially limited by the charge carrier confinement in the present dot system. Our study offers a guideline for the fabrication of quantum entangled pair sources suitable for practical use.

description: This is a comprehensive exposition of the classical moment problem using methods from the theory of finite difference operators. Among the advantages of this approach is that the Nevanlinna functions appear as elements of a transfer matrix and convergence of Pade approximants appears as the strong resolvent convergence of finite matrix approximations to a Jacobi matrix. As a bonus of this, we obtain new results on the convergence of certain Pade approximants for series of Hamburger.

description: A current flowing through a one-dimensional Kitaev chain induces a spatial modulation in its superconducting pairing, characterized by a wave vector $Q$, which is known to induce two types of topological phase transitions: one is the customary band topology transition between gapped phases, while the other is a Lifshitz transition related to the Fermi surface topology and leading to a gapless superconducting phase. We investigate the behavior of the electron density $ρ$ and the compressibility $κ$ across the two types of transitions, as a function of the model parameters. We find that the behavior of $ρ$ as a function of $Q$ and chemical potential $μ$ enables one to infer the ground state phase diagram. Moreover, the analysis of the compressibility $κ$ as a function of $μ$ enables one to distinguish the two transitions: While $κ$ exhibits a symmetric divergence across the band topology transition, it displays an asymmetric jump across the Lifshitz transition.

description: We study the deformations of a holomorphic symplectic manifold $M$, not necessarily compact, over a formal ring. We show (under some additional, but mild, assumptions on $M$) that the coarse deformation space exists and is smooth, finite-dimensional and naturally embedded into $H^2(M)$. For a holomorphic symplectic manifold $M$ which satisfies $H^1(M,{\cal O}_M) = H^2(M,{\cal O}_M)=0$, the coarse moduli of formal deformations is isomorphic to $\Spec\C[[t_1, ..., t_n]]$, where $t_1$, ... $t_n$ are coordinates in $H^2(M)$. This revised version contains one minor improvement: exposition in Subsection 5.1 has been made more detailed and rigourous.

description: Recently, the ALICE Collaboration reported an enhancement of the yield ratio of strange and multi-strange hadrons to charged pions as a function of multiplicity at mid-rapidity in proton-proton, proton-lead, lead-lead, and xenon-xenon scattering. ALICE observations provide a strong indication that a quark-gluon plasma is partly formed in high multiplicity events of both small and large colliding systems. Motivated by ALICE's results, we propose a new test for hadronic interaction models used for analyzing ultra-high-energy-cosmic-ray (UHECR) collisions with air nuclei. The test is grounded in the almost equal column-energy density in UHECR-air collisions and lead-lead collisions at the LHC. We applied the test to post-LHC event generators describing hadronic phenomena of UHECR scattering and show that these QCD Monte Carlo-based codes must be retuned to accommodate the strangeness enhancement relative to pions observed in LHC data.

We prove the surprising fact that there is a finite region in phase space that corresponds to the otherwise drifting particle being trapped by a local repulsive potential. Our result is a direct consequence of KAM-theory and, in particular, of Moser's theorem. We illustrate it by numerical phase portraits and by an analytic approximation to invariant curves.

description: Two-dimensional (2D) Dirac-like electron gases have attracted tremendous research interest ever since the discovery of free-standing graphene. The linear energy dispersion and non-trivial Berry phase play the pivotal role in the remarkable electronic, optical, mechanical and chemical properties of 2D Dirac materials. The known 2D Dirac materials are gapless only within certain approximations, for example, in the absence of SOC. Here we report a route to establishing robust Dirac cones in 2D materials with nonsymmorphic crystal lattice. The nonsymmorphic symmetry enforces Dirac-like band dispersions around certain high-symmetry momenta in the presence of SOC. Through $μ$-ARPES measurements we observe Dirac-like band dispersions in $α$-bismuthene. The nonsymmorphic lattice symmetry is confirmed by $μ$-LEED and STM. Our first-principles simulations and theoretical topological analysis demonstrate the correspondence between nonsymmorphic symmetry and Dirac states. This mechanism can be straightforwardly generalized to other nonsymmorphic materials. The results open the door for the search of symmetry enforced Dirac fermions in the vast uncharted world of nonsymmorphic 2D materials.

description: The phonon modes of the Frenkel-Kontorova model are studied both at the pinning transition as well as in the pinned (cantorus) phase. We focus on the minimal frequency of the phonon spectrum and the corresponding generalized eigenfunction. Using an exact decimation scheme, the eigenfunctions are shown to have nontrivial scaling properties not only at the pinning transition point but also in the cantorus regime. Therefore the phonons defy localization and remain critical even where the associated area-preserving map has a positive Lyapunov exponent. In this region, the critical scaling properties vary continuously and are described by a line of renormalization limit cycles. Interesting renormalization bifurcation diagrams are obtained by monitoring the cycles as the parameters of the system are varied from an integrable case to the anti-integrable limit. Both of these limits are described by a trivial decimation fixed point. Very surprisingly we find additional special parameter values in the cantorus regime where the renormalization limit cycle degenerates into the above trivial fixed point. At these ``degeneracy points'' the phonon hull is represented by an infinite series of step functions. This novel behavior persists in the extended version of the model containing two harmonics. Additional richnesses of this extended model are the one to two-hole transition line, characterized by a divergence in the renormalization cycles, nonexponentially localized phonons, and the preservation of critical behavior all the way upto the anti-integrable limit.

description: We consider quantum (unitary) continuous time evolution of spins on a lattice together with quantum evolution of the lattice itself. In physics such evolution was discussed in connection with quantum gravity. It is also related to what is called quantum circuits, one of the incarnations of a quantum computer. We consider simpler models for which one can obtain exact mathematical results. We prove existence of the dynamics in both Schroedinger and Heisenberg pictures, construct KMS states on appropriate C*-algebras. We show (for high temperatures) that for each system where the lattice undergoes quantum evolution, there is a natural scaling leading to a quantum spin system on a fixed lattice, defined by a renormalized Hamiltonian.

description: Large language models (LLMs) have garnered substantial attention due to their promising applications in diverse domains. Nevertheless, the increasing size of LLMs comes with a significant surge in the computational requirements for training and deployment. Memristor crossbars have emerged as a promising solution, which demonstrated a small footprint and remarkably high energy efficiency in computer vision (CV) models. Memristors possess higher density compared to conventional memory technologies, making them highly suitable for effectively managing the extreme model size associated with LLMs. However, deploying LLMs on memristor crossbars faces three major challenges. Firstly, the size of LLMs increases rapidly, already surpassing the capabilities of state-of-the-art memristor chips. Secondly, LLMs often incorporate multi-head attention blocks, which involve non-weight stationary multiplications that traditional memristor crossbars cannot support. Third, while memristor crossbars excel at performing linear operations, they are not capable of executing complex nonlinear operations in LLM such as softmax and layer normalization. To address these challenges, we present a novel architecture for the memristor crossbar that enables the deployment of state-of-the-art LLM on a single chip or package, eliminating the energy and time inefficiencies associated with off-chip communication. Our testing on BERT_Large showed negligible accuracy loss. Compared to traditional memristor crossbars, our architecture achieves enhancements of up to 39X in area overhead and 18X in energy consumption. Compared to modern TPU/GPU systems, our architecture demonstrates at least a 68X reduction in the area-delay product and a significant 69% energy consumption reduction.

description: As part of an international cooperative research program, the U.S. Geological Survey (USGS) and researchers from the National Gas Hydrate Program (NGHP) of India are studying the physical properties of sediment recovered during the NGHP-01 cruise conducted offshore India during 2006. Here we report on index property, acoustic velocity, and triaxial shear test results for samples recovered from the Krishna-Godavari Basin. In addition, we discuss the effects of sample storage temperature, handling, and change in structure of fine-grained sediment. Although complex, sub-vertical planar gas-hydrate structures were observed in the silty clay to clayey silt samples prior to entering the Gas Hydrate And Sediment Test Laboratory Instrument (GHASTLI), the samples yielded little gas post test. This suggests most, if not all, gas hydrate dissociated during sample transfer. Mechanical properties of hydrate-bearing marine sediment are best measured by avoiding sample depressurization. By contrast, mechanical properties of hydrate-free sediments, that are shipped and stored at atmospheric pressure can be approximated by consolidating core material to the original in situ effective stress.

Investigating the Role of the Meiotic Chromosome Axes in Mediating Crossover Designation in Wheat and Barley

description: Meiotic crossovers are skewed towards the chromosome ends in wheat and barley. As a result, ~30% of genes rarely recombine in the ‘cold regions’, resulting in linkage-drag, which can be problematic for plant breeders as beneficial traits co-segregate with undesirable traits. An increase in the number of COs, or a shift in their positions, may disrupt linkage blocks and consequently benefit breeders. Pachytene Checkpoint Protein 2 (PCH2) is a conserved AAA+ ATPase, required to remodel the chromosome axes during meiosis and ensure accurate crossover formation. Previous work in Arabidopsis thaliana pch2 mutants has shown that crossovers are more likely to cluster together on short regions of the synaptonemal complex, as well as lose the obligate crossover, in the absence of PCH2. By using different methods of gene interference (CRISPR/Cas9, TILLING and VIGS), pch2 knockouts have been generated in diploid barley and tetraploid wheat and hypomorphs have been produced in hexaploid wheat. A cytological analysis has shown that PCH2 is involved in the timing of meiosis in all three ploidies and is required for the formation of the obligate CO in tetraploid wheat, but not in diploid barley. Full synapsis is achieved in barley pch2 mutants, but not tetraploid wheat pch2 mutants, where only short ZYP1 stretches are observed, localising with class I crossover marker HEI10. In addition, ectopic recombination is observed at meiotic metaphase I in tetraploid wheat pch2 mutants, indicating loss of crossover control and possible homoeologous recombination. Immunolocalisation studies indicate that PCH2 is involved in maintaining positive interference in wheat and barley, as a shift from positive to negative interference is observed in the absence of PCH2. This thesis offers a substantial contribution of knowledge to the meiosis community, providing further understanding of the role of PCH2 in crops and, importantly, in PCH2-mediated interference in plants.

description: Word embeddings trained on large-scale historical corpora can illuminate human biases and stereotypes that perpetuate social inequalities. These embeddings are often trained in separate vector space models defined according to different attributes of interest. In this paper, we develop a unified dynamic embedding model that learns attribute-specific word embeddings. We apply our model to investigate i) 20th century gender and ethnic occupation biases embedded in the Corpus of Historical American English (COHA), and ii) biases against refugees embedded in a novel corpus of talk radio transcripts containing 119 million words produced over one month across 83 stations and 64 cities. Our results shed preliminary light on scenarios when dynamic embedding models may be more suitable for representing linguistic biases than individual vector space models, and vice-versa.

subject: Composition

description: This research project is concerned with the way in which nature is idealised through images, and questions how painting might be able to address this using visual strategies borrowed from the 18th Century aesthetic traditions of the Picturesque. Contemporary popular landscape images, often photographs, present an ideal of nature that is vast, nurturing and self-sustaining. To submit to this ideal, though enjoyable, is to overlook the lived reality of nature in all its extremes as well as the cultural and environmental problems linked to idealised views of nature. By drawing on historical and contemporary literature surrounding the Picturesque, this project explores the ways in which the closely related concepts of ‘variety’, ‘roughness’, ‘irregularity’ and ‘intricacy’ can inform contemporary landscape paintings that reflect the complex experience of nature in the real. The outcomes of this studio-based research project demonstrate how an expanded notion of these methods—including choices in composition, colour, the application of paint, and the interaction of works in a space—disrupt idealised representation by fracturing or interrupting the image, preventing a cohesive and therefore reductive reading of the landscape. This interrupted form of representation operates similarly to real nature, which refuses to be taken in at one glance. The paintings thus offer seductive representations of nature that nevertheless resist the ideal views of popular landscape imagery.

description: We use the cross correlation sum introduced recently by H. Kantz to study symmetry properties of chaotic attractors. In particular, we apply it to a system of six coupled nonlinear oscillators which was shown by Kroon et al. to have attractors with several different symmetries, and compare our results with those obtained by ``detectives" in the sense of Golubitsky et al.

Extinction and dust/gas ratio in the H I ridge region of the LMC based on the IRSF/SIRIUS near-infrared survey

description: We present a dust extinction AV map of the Large Magellanic Cloud (LMC) in the H I ridge region using the IRSF near-infrared (IR) data, and compare the AV map with the total hydrogen column density N(H) maps derived from the CO and H I observations. In the LMC H I ridge region, the two-velocity H I components (plus an intermediate velocity component) are identified, and the young massive star cluster is possibly formed by collision between them. In addition, one of the components is suggested to be an inflow gas from the Small Magellanic Cloud (SMC) which is expected to have even lower metallicity gas (Fukui et al. 2017, PASJ, 69, L5). To evaluate dust/gas ratios in the H I ridge region in detail, we derive the AV map from the near-IR color excess of the IRSF data updated with the latest calibration, and fit the resultant AV map with a combination of the N(H) maps of the different velocity components to successfully decompose it into the 3 components. As a result, we find difference by a factor of 2 in AV /N(H) between the components. In additon, the CO-to-H2 conversion factor also indicates difference between the components, implying the difference in the metallicity. Our results are likely to support the scenario that the gas in the LMC H I ridge region is contaminated with an inflow gas from the SMC with a geometry consistent with the on-going collision between the two velocity components.

description: Heavy metal pollution has become one of the most serious environmental pollution problems. This study aimed to determine the adsorption and desorption characteristics of Ni2+ and Cu2+ by bio-mineral which was induced by Bacillus subtilis, and to explore the effect of pH on adsorption characteristics. The results showed that the Langmuir model gave a better fit to the experimental data than the Freundlich model, which demonstrated the adsorption was of a single-molecule layer form. The maximum adsorption capacities of the bio-mineral for Ni2+ and Cu2+ were determined as 67.114 mg/g and 69.930 mg/g, respectively. The desorption rates of Ni2+ and Cu2+ were very low, especially for Ni2+ which was almost 0. Besides, the bio-mineral maintained high adsorption capability for metals ions within a wide pH range (pH ≥ 3). It did not show any new phases after adsorption of Ni2+ and Cu2+ tested by FTIR, indicating that the bio-mineral and heavy metal ions might mainly physically be adsorbed. The bio-mineral has a larger internal and external specific surface area, pore volume and colloidal properties which are beneficial for the adsorption of metals ions, but shows limits in desorption. This study provides a theoretical basis for the utilization of bio-mineral and opens a new perspective for the remediation of heavy metals pollution.
