On Superdeterministic Rejections of Settings Independence

Relying on some auxiliary assumptions, usually considered mild, Bell's theorem proves that no local theory can reproduce all the predictions of quantum mechanics. In this work, we introduce a fully local, superdeterministic model that, by explicitly violating settings independence--one of these auxiliary assumptions, requiring statistical independence between measurement settings and systems to be measured--is able to reproduce all the predictions of quantum mechanics. Moreover, we show that, contrary to widespread expectations, our model can break settings independence without an initial state that is too complex to handle, without visibly losing all explanatory power and without outright nullifying all of experimental science. Still, we argue that our model is unnecessarily complicated and does not offer true advantages over its non-local competitors. We conclude that, while our model does not appear to be a viable contender to their non-local counterparts, it provides the ideal framework to advance the debate over violations of statistical independence via the superdeterministic route.Comment: 38 pages, 2 figure

Performance evaluation of a storage model for OR-parallel execution of logic programs

As the next step towards a computer architecture for parallel execution of logic programs we have implemented four refinements of the basic storage model for OR-Parallelism and gathered data about their performance on two types of shared memory architectures, with and without local memories. The results show how the different properties of the implementations influence performance, and indicate that the implementations using hashing techniques (hash windows) will perform best, especially on systems with a global storage and caches. We rise the question of the usefulness of the simulation technique as a tool in developing new computer architectures. Our answer is that simulations can not give the ultimate answers to the design questions, but if only the judiciosly chosen parts of the machine are simulated on a detailed level, then the obtained results can give a very good guidance in making design choice

From locality to factorizability: a novel escape from Bell's theorem

While initial versions of Bell's theorem captured the notion of locality with the assumption of factorizability, in later presentations, Bell argued that factorizability could be derived from the more fundamental principle of local causality. Here we show that, contrary to what is commonly assumed, in order to derive factorizability from the principle of local causality, a non-trivial assumption, similar but strictly independent of settings independence, is required. Loosely speaking, such an extra assumption demands independence between the states of the measurement apparatuses. We conclude that it is possible to construct a model, satisfying both the principle of local causality and settings independence, but that, in virtue of violating this additional assumption--and thus factorizability--is able to break Bell's inequality

Transport signatures of Van Hove singularities in mesoscopic twisted bilayer graphene

Magic-angle twisted bilayer graphene exhibits quasiflat low-energy bands with Van Hove singularities close to the Fermi level. These singularities play an important role in the exotic phenomena observed in this material, such as superconductivity and magnetism, by amplifying electronic correlation effects. In this work, we study the correspondence of four-terminal conductance and the Fermi surface topology as a function of the twist angle, pressure, and energy in mesoscopic, ballistic samples of small-angle twisted bilayer graphene. We establish a correspondence between features in the wide-junction conductance and the presence of Van Hove singularities in the density of states. Moreover, we identify additional transport features, such as a large, pressure-tunable minimal conductance, conductance peaks coinciding with nonsingular band crossings, and unusually large conductance oscillations as a function of the system size. Our results suggest that twisted bilayer graphene close the magic angle is a unique system featuring simultaneously large conductance due to the quasiflat bands, strong quantum nonlinearity due to the Van Hove singularities, and high sensitivity to external parameters, which could be utilized in high-frequency device applications and sensitive detectors.publishedVersionPeer reviewe

Simultaneous Multi-Harmonic Imaging of Nanoparticles in Tissues for Increased Selectivity

We investigate the use of Bismuth Ferrite (BFO) nanoparticles for tumor tissue labelling in combination with infrared multi-photon excitation at 1250 nm. We report the efficient and simultaneous generation of second and third harmonic by the nanoparticles. On this basis, we set up a novel imaging protocol based on the co-localization of the two harmonic signals and demonstrate its benefits in terms of increased selectivity against endogenous background sources in tissue samples. Finally, we discuss the use of BFO nanoparticles as mapping reference structures for correlative light-electron microscopy.Comment: 19 pages, 6 figure

Effect of sex and RYR1 gene mutation on the muscle proteomic profile and main physiological biomarkers in pigs at slaughter

Gender and RYR1 gene mutation might have an effect on the muscle metabolic characteristics and on the animal's stress at slaughter, which could influence the process of muscle-to-meat conversion. Forty-eight pigs were distributed in a design including two factors: sex (male/female) and RYR1 genotype (NN/Nn). At slaughter, physiological blood biomarkers and muscle proteome were analyzed and carcass and meat quality traits were registered. Females had higher serum levels of glucose, urea, C-reactive protein "CRP", Pig-MAP and glutation-peroxidase "GPx" and lower levels of lactate, showed faster muscle pH decline and higher meat exudation. RYR1 mutation increased serum creatinine, creatine kinase and CRP and decreased GPx. The proteomic study highlighted significant effects of gender and RYR1 genotype on proteins related to fibre composition, antioxidant defense and post mortem glycolytic pathway, which correlate to differences of meat quality. This study provides interesting information on muscle biomarkers of the ultimate meat quality that are modulated by the animal's individual susceptibility to stress at slaughter.info:eu-repo/semantics/acceptedVersio

Local government investment as a factor of local development on the example of Pawłów.

Rozwój lokalny to proces niezwykle pożądany, który odbywać może się za sprawą różnego rodzaju czynników i instytucji. Celem niniejszej pracy jest omówienie wpływu inwestycji realizowanych przez jednostki samorządu terytorialnego, na rozwój lokalny. W pracy tej skupiono się na inwestycjach, które realizuje gmina, czyli podstawowa i najniżej obsadzona w hierarchii administracji publicznej jednostka.W pracy zostały omówione podstawowe czynniki rozwoju lokalnego oraz sposoby zarządzania tymże rozwojem na szczeblu lokalnym, ze szczególnym uwzględnieniem strategii rozwoju gminy, jako podstawowego narzędzie oddziałującego na rozwój lokalny. W dalszej części pracy zostały omówione różne rodzaje inwestycji, a zwłaszcza uwaga została skoncentrowana na inwestycjach realizowanych przez gminę, sposobach zarządzania nimi oraz źródłami finansowania. Umiejętność właściwego dysponowania i zarządzania posiadanymi przez gminę środkami może prowadzić do efektywnego rozwoju lokalnego.Local development is a process highly desirable, which could be a result of various factors and institution’s activities.
