description: In probabilistic conditions, people choose low-payoff alternatives on some trials, thus failing to maximize their payoffs. We suggest that such behavior implicates exploration of task rules by choosing risky options instead of exploiting more rewarding alternatives. We hypothesized that exploration would affect brain responses to feedback. Further, a shift to exploration develops gradually and, therefore, a decision to make an exploratory choice may be observed on trials preceding risky choices. We investigated beta power (16–30 Hz) in the magnetoencephalographic data from 62 healthy participants performing a two-choice probabilistic gambling with monetary gains and losses. The effects were found at 600–800 ms after feedback onset in frontal, central and occipital brain regions. On trials preceding risky choices we identified a decrease in beta power which implies a change in decision-making strategy and a shift towards cognitive flexibility and exploration. An increase in beta power during risky decisions indicates that reward learning mechanisms are implicated. Increases in beta power following losses in risky choices indicates at the process of updating the internal representation of the task. In summary, current findings reveal that the outcomes of exploratory trials are processed differentially, while there is no evidence of such processing on exploitatory trials. This corroborates the hypothesis that exploratory choices represent active probing into the surmised task rules. Current findings also suggest that the processing of outcomes preceding the exploratory trials is altered in such a way that subjects override their intention to use the utility model and reset their behavioral strategy.

description: Definitions of obedience require the experience of conflict in response to an authority’s demands. Nevertheless, we know little about this conflict and its resolution. Two experiments tested the suitability of the ‘object-destruction paradigm’ for the study of conflict in obedience. An experimenter instructed participants to shred bugs (among other objects) in a manipulated coffee grinder. In contrast to the demand condition, participants in the control condition were reminded of their free choice. Both received several prods if they defied the experimenter. Results show that participants were more willing to kill bugs in the demand condition. Self-reported negative affect was increased after instructions to destroy bugs relative to other objects (Experiments 1 and 2). In Experiment 2, compliant participants additionally showed an increase in tonic skin conductance and, crucially, self-reported more agency and responsibility after alleged bug-destruction. These findings elucidate the conflict experience and resolution underlying obedience. Implications for prominent explanations (agentic shift, engaged followership) are discussed.

description: Spontaneous activity is known to be a characteristic feature of the vast majority of the neocortical principal cells including neurons of the primary sensory areas. The question of how spontaneous activity interacts with perception and encoding of sensory information remains open. In the present study, pyramidal neurons of the mouse primary visual cortex were recorded extracellularly under urethane anesthesia and simultaneous single-channel EEG recording was performed. To evaluate orientation and direction selectivity of the recorded neurons, mice were presented with visual stimuli consisting of moving sinusoidal gratings of different orientations displayed on a monitor. We noted quite regular bursts of generalized brain activity that were manifested in the recorded neuron as bundles of action potentials accompanied with a distinctive EEG pattern. Clearly, whenever such spontaneous activity shows up during visual stimulation, it is considered as noise, which significantly compromises the characteristics of the neuron’s measured visual response. To eliminate this effect, we developed a machine learning-based algorithm that enables to identify EEG predictors of generalized spontaneous activity and then to exclude spontaneous (i.e. not evoked by visual stimulation) action potentials from the recording. Our algorithm was shown to reliably detect action potentials that have been caused by generalized brain activity. Removal of action potentials of this origin from extracellular recordings obtained during visual stimulation allows for a more adequate estimation of parameters of neuronal receptive fields, in particular their orientation selectivity.
Boron: a Hunt for Superhard Polymorphs

description: Boron is a unique element, being the only element, all known polymorphs of which are superhard, and all of its crystal structures are distinct from any other element. The electron-deficient bonding in boron explains its remarkable sensitivity to even small concentrations of impurity atoms and allows boron to form peculiar chemical compounds with very different elements. These complications made the study of boron a great challenge, creating also a unique and instructive chapter in the history of science. Strange though it may sound, the discovery of boron in 1808 was ambiguous, with pure boron polymorphs established only starting from the 1950s-1970s, and only in 2007 was the stable phase at ambient conditions determined. The history of boron research from its discovery to the latest discoveries pertaining to the phase diagram of this element, the structure and stability of beta-boron, and establishment of a new high-pressure polymorph, gamma-boron, is reviewed.

description: Cognitive status and EEG in the theta, alpha, and beta ranges were studied using cluster analysis by discrete optimization in patients with cardiovascular disease in the preoperative period of coronary artery bypass grafting. The cognitive status was measured by Mini-Mental State Examination (MMSE) scale, and an integral indicator of cognitive status (IICS) formed on the basis of complex testing the indices of visual-motor responses, attention, and memory. The new method of clustering the EEG power and the cognitive status made it possible to distinguish groups of patients differenced by cognitive reserves. The IICS better differentiates groups than MMSE. The factors of age and education were decisive only in specific groups. The clusters characterized by the most represented cognitive reserves according to the higher both MMSE and IICS indicators included less pronounced activation of the cortex according to more power of the theta, alpha, and less beta rhythm. Patients with supposedly minimal reserves are differed by a low level of cognitive status, as well as education level together with higher activation state of the cortex. The third type of clusters was distinguished by an unstable composition due to the variability of EEG indicators in it, mostly cortical activity at the alpha1 frequencies. The EEG neurophysiological approach, together with cognitive screening and proposed clustering analysis, could be helpful in understanding mechanisms of cognitive reserves and identify the risk factors of postoperative cognitive dysfunction in patients with brain cardiovascular damage.

A preliminary study of nest-site competition in a group of hole-nesting birds
Creators: name: McLaren, William David
Publisher: name: University of British Columbia
Year: 2011

description: This study was restricted to birds using tree-holes as nest-sites. Of a total of 20 species in the study area, only 13 were sufficiently abundant to merit consideration. These fell into three natural groups on the basis of hole size, with only one euryoecious species (Iridoprocne bicolor) nesting in all three groups. Only the group based on holes made by the Colaptes woodpeckers (Flickers) can presently be construed as showing evidence of nest-site competition. Physical and ecological characteristics of nest-sites are analyzed in terms of intensification or amelioration of nest-site competition. The competing species, all using holes made by Colaptes cafer, are Sturnus vulgaris, Sialia currucoides, Bucephala albeola, Iridoprocne bicolor and Falco sparverius. The data suggest that although competition is now present in this group, it may have been absent before the advent of Sturnus in the avifauna. Neither selection for different sites nor competitive exclusion seem to have occurred before the appearance of Sturnus, which now occupies roughly 25% of all available nests, but one or both of these may now be going on.
Semiparametric and Nonparametric Methods in Econometrics

description: The main objective of this workshop was to bring together mathematical statisticians and econometricians who work in the field of nonparametric and semiparametric statistical methods. Nonparametric and semiparametric methods are active fields of research in econometric theory and are becoming increasingly important in applied econometrics. This is because the flexibility of non- and semiparametric modelling provides important new ways to investigate problems in substantive economics. Moreover, the development of non- and semiparametric methods that are suitable to the needs of economics presents a variety of mathematical challenges. Topics to be addressed in the workshop included nonparametric methods in finance, identification and estimation of nonseparable models, nonparametric estimation under the constraints of economic theory, statistical inverse problems, long-memory time-series, and nonparametric cointegration.

description: Mitochondria-endoplasmic reticulum contacts (MERC) are known as one of the key regulators of many cell functions. In particular, MERC effects on the mobility and morphology of mitochondria, exchange of calcium and lipids between organelles, and participates in the processes of autophagy and apoptosis that are crucial for neuronal development. MERC can influence the functioning of the neurotrophic factor BDNF through the activation of the Sigma-1 receptor. That points to the presence of feedback i.e. itself BDNF influence on the structural characteristics of MERC. At the same time, the effect of chronic stimulation of BDNF or blockade of TrkB receptors on an ability to form contacts between mitochondria and ER is different and depends on cellular compartment.

description: The two major approaches to chiral conformal field theory – one based on operator algebras and one based on vertex algebras – both lead to representation categories which are tensor categories and, in the case of rational chiral conformal field theories, more specifically modular tensor categories. In this Arbeitsgemeinschaft, we have studied algebraic structures related to tensor categories arising in conformal field theory. The notion of a module category over this tensor category is central in the construction of a full local conformal field theory in various frameworks.

description: During the past century, there has been considerable discussion and analysis of the motion of a point charge, taking into account "self-force" effects due to the particle's own electromagnetic field. We analyze the issue of "particle motion" in classical electromagnetism in a rigorous and systematic way by considering a one-parameter family of solutions to the coupled Maxwell and matter equations corresponding to having a body whose charge-current density $J^a(λ)$ and stress-energy tensor $T_{ab} (λ)$ scale to zero size in an asymptotically self-similar manner about a worldline $γ$ as $λ\to 0$. In this limit, the charge, $q$, and total mass, $m$, of the body go to zero, and $q/m$ goes to a well defined limit. The Maxwell field $F_{ab}(λ)$ is assumed to be the retarded solution associated with $J^a(λ)$ plus a homogeneous solution (the "external field") that varies smoothly with $λ$. We prove that the worldline $γ$ must be a solution to the Lorentz force equations of motion in the external field $F_{ab}(λ=0)$. We then obtain self-force, dipole forces, and spin force as first order perturbative corrections to the center of mass motion of the body. We believe that this is the first rigorous derivation of the complete first order correction to Lorentz force motion. We also address the issue of obtaining a self-consistent perturbative equation of motion associated with our perturbative result, and argue that the self-force equations of motion that have previously been written down in conjunction with the "reduction of order" procedure should provide accurate equations of motion for a sufficiently small charged body with negligible dipole moments and spin. There is no corresponding justification for the non-reduced-order equations.

Mini-Workshop: Geometric Measure Theoretic Approaches to Potentials on Fractals and Manifolds
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2007
Subjects: subject: Konferenzschrift
subject: 510

description: The workshop brought together researchers and graduate students from diﬀerent areas of mathematics, such as analysis, probability theory, geometry, and number theory. The topics of joint interest were motivated by recent problems in potential theory with impacts into these areas: • discrete approximation to energy minimising measures • potential theory on fractals and manifolds • geometric measure theory on fractals • probabilistic potential theory • spectral theory on fractals and sets with fractal boundary. The format of a mini-workshop was especially well-suited for our subject, since it allowed enough time for personal discussions besides the talks given by the participants. The concept of energy of a charge distribution on a subset of Euclidean space is one of the core subjects of potential theory. Recent generalisations of this concept to hyper-singular energy kernels and discrete N –point distributions exhibit a close connection with ideas from geometric measure theory. A recent article by two of the organisers shows that N –point conﬁgurations minimising the discrete energy in the hyper-singular case can be used to characterise the Hausdorﬀ measure on d–dimensional d–rectiﬁable manifolds embedded in Euclidean space. Such minimal energy point sets can be used for the discretisation of manifolds, which has numerous applications. On the other hand discretisation by graph structures is a common means for analysis on fractal structures. Usually, a diﬀusion and an associated Laplace operator are deﬁned by rescaling discrete random walks and their transition operators on the approximating graphs.

description: Emotion regulation is a popular research topic in social, clinical, cognitive psychology, and neurophysiology. Event-related potentials (ERPs) studies have high temporal resolution and are therefore conventionally used in emotion research to study the patterns of emotion processing. Advances in digital technologies are promoting neuro-psychological research of emotion and attention in virtual reality (VR). In this work, for the first time, we investigated how the presented emotional facial expressions in VR modulate ERP components in conditions of different combinations of passive or active attention and random or linear presentation sequence. We found the higher amplitude of the C1, N170, P2, P3, P4 ERP components in the condition of active attention compared to passive attention during the random presentation of emotional 3D facial expression. During the linear presentation of emotional 3D facial expressions, a statistically significant difference was found only for the C1 ERP component in conditions of both passive and active attention. We proved that the P2 ERP component represents the perception of positive and negative 3D facial expressions encoding the emotional valence of the stimuli. We also found no statistically significant difference in latency of ERP components between passive and active attention to emotional 3D facial expressions.
Survival probability for diffractive dijet production in p-pbar collisions from next-to-leading order calculations

description: We perform next-to-leading order calculations of the single-diffractive and non-diffractive cross sections for dijet production in proton-antiproton collisions at the Tevatron. By comparing their ratio to the data published by the CDF collaboration for two different center-of-mass energies, we deduce the rapidity-gap survival probability as a function of the momentum fraction of the parton in the antiproton. Assuming Regge factorization, this probability can be interpreted as a suppression factor for the diffractive structure function measured in deep-inelastic scattering at HERA. In contrast to the observations for photoproduction, the suppression factor in proton-antiproton collisions depends on the momentum fraction of the parton in the Pomeron even at next-to-leading order.

description: The extracellular matrix plays an important role in brain function. Recent findings suggest that disruption of hyaluronan-based extracellular matrix can cause seizure-like activity (Vedunova et al., 2013). Epilepsy can be characterized by an excessive influx of Ca2+ ions through (Ca2+) – permeable AMPA receptors, which may, in certain circumstances, contribute to seizures. Ca2+ – permeability of these receptors is dependent on RNA-editing of pre-mRNA transcript of GluA2 subunit at the Q/R site. Regulation of this process is carried out by a special nuclear enzyme, ADAR2 (Adenosine Deaminase Acting on RNA-2). Thus, the study of the principle of operation of this enzyme can contribute to understanding the mechanism of epileptogenesis.

description: A Previously traditional methods were sufficient to protect the information, since it is simplicity in the past does not need complicated methods but with the progress of information technology, it become easy to attack systems, and detection of encryption methods became necessary to find ways parallel with the differing methods used by hackers, so the embedding methods could be under surveillance from system managers in an organization that requires the high level of security. This fact requires researches on new hiding methods and cover objects which hidden information is embedded in. It is the result from the researches to embed information in executable files, but when will use the executable file for cover they have many challenges must be taken into consideration which is any changes made to the file will be firstly detected by untie viruses, secondly the functionality of the file is not still functioning. In this paper, a new information hiding system is presented. The aim of the proposed system is to hide information (data file) within image page of execution file (EXEfile) to make sure changes made to the file will not be detected by universe and the functionality of the exe.file is still functioning after hiding process. Meanwhile, since the cover file might be used to identify hiding information, the proposed system considers overcoming this dilemma by using the execution file as a cover file.

description: Plastic changes in the neurons of the amygdala during learning in fear conditioning and their contribution to the modifications of behavior are well known, but the impact of hippocampal neurons in this behavioral task is not well studied to date. Recently a novel technique for simultaneous recording of calcium signal in multiple neurons in the brain of awake freely moving animals by miniature fluorescent microscope (miniscope) was developed. With the use of the miniscope, we have investigated neuronal activity in the CA1 area of hippocampus during memory formation and a recall in the task of contextual fear conditioning and correlated it with recorded mice behavior. Three epochs during learning were analyzed in mice behavior and brain activity: 120 s before, 2 s during, and 30 s after the electric shock. Memory retrieval was induced by placement of the animals for 180 s in the same context 24 h and 48 h after learning. The total amount of the neurons recorded in three mice was 507 during learning and 401 during memory retrieval. The patterns of neuronal activity were analyzed and discussed.

description: The information influence in the modern globalizing world is a serious challenge to the security of any state. This article presents the results of an experimental study of the way the modern Internet media affect the cognitive attitudes of individuals on the example of two leading international TV channels – RT and BBC. In order to conduct this study our team developed an experimental plan for the psychophysiological recording of deformation of cognitive attitudes under the external informational influence. The study was conducted at the Department of Psychophysiology of the Lobachevsky State University of Nizhny Novgorod from March to May 2018. The experiment was conducted on twenty-one (21) volunteers aged from nineteen to thirty-six, the average age of the group being twenty-four. Since the largest audience of modern communication networks is the younger generation, they became the focus of the study. The authors analyzed the deformations of the cognitive attitudes of individuals to identify distinctive features of these processes.

description: Ecosystematic methods were used to study synecological problems in the Alpine Zone of Garibaldi Park, British Columbia. The influence of snow pack and its effects upon soils and the distribution of vegetation are considered. The successional trend of plant communities in the subalpine alpine ecotone and alpine zone is presented. The plant succession is closely related to environmental changes, particularly to the duration of the snow pack and soil forming processes. The Phyllodoceto - Cassiopetum mertensianae can be regarded as the zonal community in the Alpine Zone above 5,500 feet. It is shown that alpine zone ranges from 5,500 feet to the highest summits over 8,000 feet. Environmental conditions are correlated with units of vegetation which allow the recognition of twelve plant associations. The associations are arranged in groups which tend to characterize the habitats in which they are found. The associations are grouped as follows:- A. Snow patch group i) Gymnomitrieto - Polytrichetum norvegici a. sub-assoc. gymnomitrieto - polytrichetum norvegici b. sub-assoc. polytrichetosum piliferi ii) Cariceturn nigricantis iii) Sibbaldietum procumbentis B. Chomophytic group i) Caricetum spectabilis ii) Luetkeetum pectinatae iii) Anaphaleto - Lupinetum arctici C. Alpine meadow group i) Mimuleto - Epilobietum latifolii ii) Valerianetum sitchensis D. Rupicolous group i) Junipereto - Penstemonetum menziesii ii) Silenetum acaulis E. Alpine heather group i) Phyllodoceto - Cassiopetum mertensianae F. Krummholz group i) Abieteto - Chamaecyparetum nootkatensis G. Peat bog group i) Sphagnum

description: Gamma band oscillations (25 70 Hz) play an important role in processing of information by neocortical neurons. In simple cells of the cat's visual cortex, it was previously shown that strength of gamma oscillations is modulated by the membrane potential oscillations at the temporal frequency of the stimulus. More recently, theoretical studies using a conductance-based neuronal model have shown that this coupling significantly improves visual stimulus encoding. Due to the availability of a broad range of genetic tools, mice had recently become an important experimental subject for research in various fields of neuroscience, including visual physiology. It has been suggested that gamma oscillations in the mouse visual cortex play a minor role in visual processing due to the lack of specialized neurons that take part in generating gamma oscillations. Here we show, using patch clamp recording from simple cells in the visual cortex of anesthetized mice, that the strength of gamma oscillations is modulated by the phase of stimulus-induced oscillations during visual stimulation with moving gratings. In addition, using patch clamp recording from mouse visual cortex neurons in slices, we demonstrated benefits of gamma activity modulation for encoding of slow sinusoidal signals into sequences of action potentials. Thus, the phenomenon of amplitude modulation of gamma oscillations by temporal frequency of stimulus, originally described in the visual system of cats, may represent a universal mechanism that improves encoding of visual information which is present even in animals with a relatively poorly developed visual system, such as mice.

description: We report on a new collective phenomenon in metamaterials: spectral line collapse with increasing number of the unit cell resonators (meta-molecules). Resembling the behaviour of exotic states of matter, such as Bose-Einstein condensates of excitons and magnons, this new effect is linked to the suppression of radiation losses in periodic arrays. We demonstrate experimentally spectral line collapse at microwave, terahertz and optical frequencies. It emerges as a universal and truly scalable effect underpinned by classical electromagnetic interactions between the excited meta-molecules.

On the Well-posedness of the Schrödinger-Korteweg-de Vries system

description: We prove that the Cauchy problem for the Schrödinger-Korteweg-de Vries system is locally well-posed for the initial data belonging to the Sovolev spaces $L^2(\R)\times H^{-{3/4}}(\R)$. The new ingredient is that we use the $\bar{F}^s$ type space, introduced by the first author in \cite{G}, to deal with the KdV part of the system and the coupling terms. In order to overcome the difficulty caused by the lack of scaling invariance, we prove uniform estimates for the multiplier. This result improves the previous one by Corcho and Linares.

CHARACTERISTICS OF SYNCHROTRON RADIATION

Publisher: name: INFN Open Access Repository
Year: 1991

description: When relativistic electrons experience centripetal acceleration due to the presence of a magnetic field, they emit electromagnetic waves that are commonly called 'synchrotron radiation' because first observed in the visible region, at the 70 MeV small electrosynchrotron, by a research group working in 1947 at the General Electric Research Laboratory (Schenentady - N.Y.). In 1944, Ivanenko and Pomernchuk drew attention to the fact that the electron beam circulating in the cyclic inductive accelerator, called the 'betatron', was interrupted because of the high quality of energy irradiates by the electrons. Originally, synchrotron radiation struck the attention of the physicists because of its very interesting and unusual properties, such as big power, high degree of collimation in the vertical plane, very broad spectral distribution and linear polarization on the orbital plane.The emission of radiation from relativistic particles travelling in a magnetic field has, more recently, attracted the attention of astrophysicists as well, since the synchrotron radiation mechanism has been found present, from the radiofrequency range to the X-ray range, also in the ratio emission of Crab Nebula and several supernovae. In 1950, synchrotron radiation became more important in connection with the development and construction of cyclic accelerators like electrosyncrotrons. This new type of accelerator was able to produce increasingly intense photon beams used not only to carry out pioneering works in several different fields^,3,4,5,6 but also as a tool to understand the dynamics of the particles in the accelerator. In 1955 the spectral and angular distributions of the ultra violet radiation emitted by the 300-MeV Cornell synchrotron were examined by Tomboulian and Hartman for various electron energies over a wide photon energy range.

description: Exact String Matching is an essential issue in many computer science applications. Unfortunately, the performance of Exact String Matching algorithms, namely, executing time, does not address the needs of these applications. This paper proposes a general platform for improving the existing Exact String Matching algorithms executing time, called the PXSMAlg platform. The function of this platform is to parallelize the Exact String Matching algorithms using the MPI model over the Master or Slaves paradigms. The PXSMAlg platform parallelization process is done by dividing the Text into several parts and working on these parts simultaneously. This improves the executing time of the Exact String Matching algorithms. We have simulated the PXSMAlg platform in order to show its competence, through applying the Quick Search algorithm on the PXSMAlg platform. The simulation result showed significant improvement in the Quick Search executing time, and therefore extreme competence in the PXSMAlg platform.

Being naked in dreams: Analysis of a long dream series
Creators: name: Schredl, Michael
Publisher: name: International Journal of Dream Research
Year: 2021

description: Some theorists claimed that dreams show mainly features of primary consciousness but lack the characteristics of secondary consciousness like self-reflection, abstract thinking, and metacognition. One approach to this question is to study dreams in which the basic pattern of the dream involves higher-order consciousness processing. In a dream series of 12,159 dreams, the topic of “being totally or partially nude” was analyzed since the associated shame/embarrassment is a result of the dreamer’s worries about what others might think of him or her (theory of mind). About 1.08% of the dreams included this topic, showing a large variability regarding the content. Overall, the findings offered strong support against the views that dreams are single-minded or mainly characterized by primary consciousness processes. Studying typical dreams that include − almost per definition − secondary consciousness processes is a promising approach toward clarifying the cognitive capabilities within dreams.
