description: Η παρούσα διπλωματική εργασία αποτελεί μια διεπιστημονική γέφυρα μεταξύ του αντικειμένου της σεξολογίας και του αντικειμένου της μουσειολογίας. Ένα από τα θεμελιώδη ζητήματα που αντιμετωπίζει η Ελλάδα είναι η έλλειψη της σεξουαλικής διαπαιδαγώγησης τόσο στους νέους και τα παιδιά της όσο και στου ενήλικες. Έτσι, με την παρούσα εργασία και την προτεινόμενη λύση της πάνω στο θέμα μέσω της συμβολής της μουσειολογίας, επιχειρείται να καλυφθεί αυτό το κενό τόσο σε βιβλιογραφικό, όσο και σε πρακτικό επίπεδο. Μέσω της καταγραφής της ορολογίας γύρω από τη σεξουαλικότητα, της σύντομης ιστορικής ανασκόπησης, καθώς και της αναπαράστασής της μέσα από ένα μουσειακό-εκθεσιακό χώρο ανοιχτό στο κοινό, γίνεται κατανοητό πόσο καθοριστικό ρόλο έχει στη ζωή μας η σεξουαλικότητα. Συνεπώς, προτείνεται η δημιουργία μιας έκθεσης με κεντρικό θέμα το σεξ και τις εκφάνσεις του στις μέρες μας. Η έκθεση αυτή θα έχει ως βαθύτερο σκοπό την ορθή ενημέρωση του κόσμου γύρω από όλα τα θέματα που σχετίζονται με τη σεξουαλικότητα μέσω του αποκλειστικά παιδαγωγικού της χαρακτήρα.
description: This dissertation is an interdisciplinary bridge between the subject of sexology and the subject of museology. One of the most fundamental issues that Greece is facing nowadays is the lack of sex education both for its youth and children, and its adults. Thus, with this dissertation and its proposed solution through the contribution of museology, an attempt is made to fill this gap both in bibliographical and in practical terms. Through the recording of the terminology around sexuality, a brief historical review and its representation throughout a museum-exhibition open to the public, people can realise and learn how crucial sexuality is in our lives. Therefore, it is suggested to create a report about an exhibition with sex and its manifestations nowadays as its central theme. This exhibition will have the deeper purpose of properly informing the public about all issues related to sexuality through its solely pedagogical character.

description: The Casimir effect for parallel plates in the presence of compactified universal extra dimensions within the frame of Kaluza-Klein theory is analyzed. Having regularized and discussed the expressions of Casimir force in the limit, we show that the nature of Casimir force is repulsive if the distance between the plates is large enough and the higher-dimensional spacetime is, the greater the value of repulsive Casimir force between plates is. The repulsive nature of the force is not consistent with the experimental phenomena.

From supported membranes to tethered vesicles: lipid bilayers destabilisation at the main transition

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We report results concerning the destabilisation of supported phospholipid bilayers in a well-defined geometry. When heating up supported phospholipid membranes deposited on highly hydrophilic glass slides from room temperature (i.e. with lipids in the gel phase), unbinding was observed around the main gel to fluid transition temperature of the lipids. It lead to the formation of relatively monodisperse vesicles, of which most remained tethered to the supported bilayer. We interpret these observations in terms of a sharp decrease of the bending rigidity modulus $κ$ in the transition region, combined with a weak initial adhesion energy. On the basis of scaling arguments, we show that our experimental findings are consistent with this hypothesis.

description: We propose a fast mixed-state control scheme to transfer the quantum state along designable trajectories in Hilbert space, which is robust to multiple decoherence noises. Starting with the dynamical invariants of open quantum systems, we present the shortcuts to adiabaticity (STAs) of open quantum systems at first, then apply the STAs to speed up the adiabatic steady process. Our scheme drives open systems from a initial steady state to a target steady state by a controlled Liouvillian that possesses the same form as the reference (original) one which is accessible in present-day experiments. The experimental observation with current available parameters for the nitrogen-vacancy (NV) center in diamond is suggested and discussed.

Notes on High Energy Limit of Bosonic Closed String Scattering Amplitudes

description: We study bosonic closed string scattering amplitudes in the high-energy limit. We find that the methods of decoupling of high-energy zero-norm states and the high-energy Virasoro constraints, which were adopted in the previous works to calculate the ratios among high-energy open string scattering amplitudes of different string states, persist for the case of closed string. However, we clarify the previous saddle-point calculation for high-energy open string scattering amplitudes and claim that only (t,u) channel of the amplitudes is suitable for saddle-point calculation. We then discuss three evidences to show that saddle-point calculation for high-energy closed string scattering amplitudes is not reliable. By using the relation of tree-level closed and open string scattering amplitudes of Kawai, Lewellen and Tye (KLT), we calculate the high-energy closed string scattering amplitudes for arbitrary mass levels. For the case of high-energy closed string four-tachyon amplitude, our result differs from the previous one of Gross and Mende, which is NOT consistent with KLT formula, by an oscillating factor.

description: This paper discusses alternative aggregations that can be used to code business sectors using the census information on different occupations and employment status categories of entrepreneurs and workers. The paper discusses how sector aggregations can be constructed that classify business proprietors by the type of economic activity in which they were engaged, and also the sector of activity for those that were clearly not entrepreneurs. It defines two classifications at two levels of aggregation that are used in subsequent analysis: ID18 and ID50 used for sector/entrepreneurship coding; and EA17 and EA51 used for sector/whole economically active coding. It compares this coding with the more detailed coding in I-CeM, that used for the PST occupational classification system devised by Wrigley, and with the codes used in modern mainstream industrial classifications of sectors and occupational groups.
Approaches to action
Creators: name: Carnie, Euan Findlay
Publisher: name: University of British Columbia
Year: 2008

description: The objective of this thesis is to introduce recent philosophy of mind to philosophy of action in an attempt to evaluate the three currently dominant theories of action. These theories each concur with the general consensus in philosophy of action that the acts of an agent are causally derived. Yet, there is still dispute regarding the exact nature of the causation. This disagreement is reflected in the differences between the identity theory, functionalism, and eliminative materialism. The identity theory, as described by Donald Davidson and Colin McGinn, states that materially instansiable beliefs and desires are the causes of action. However, problems arise from a lack of a priori validity, difficulties regarding the type of reduction or identification needed, and an unreasonable suppression of misrepresentation. There are also questions concerning the identity theory's account of learning, memory, and imagination. As a successful remedy has yet to appear, charges of theoretical stagnation have also gained momentum. Nevertheless, faults in a theory do not automatically entail its elimination, and many feel that the predicted demise of the belief and desire model has been greatly exaggerated. For instance, functionalists like Daniel Dennett retain the belief and desire structure, but endeavor to avoid the ontological difficulties which beset the identity theory by functionally defining beliefs and desires. Unfortunately, this merely leads to indiscriminate ascriptions of belief and desire to subjects not normally associated with such attributes. Functionalists, however, do tacitly recognize the legitimacy of a more empirical outlook in describing the causes of action. This empirical approach, referred to as eliminative materialism, is the basis of claims by theorists such as Paul Churchland that the belief and desire causal framework is fundamentally flawed, and hence, should be subject to an elimination similar to the abandonment of theories like alchemy, astrology, and caloric fluidity. In light of the defects of the identity and functionalists theories, and enhanced by the appearance of a promising alternative which coalesces well with Churchland's conclusions (i.e.: connectionist parallel processing models of cognition), the balance now appears to be tipped in favour of the eliminativists. Yet, the question remains of just how much of an elimination of the ontological, practical, or semantic facets of the belief/desire model is warranted. While the final answer awaits confirmation, it seems evident that the solution will only be resolved by maintaining an eliminative approach towards the causes of action.

description: We describe SAFIUS, a secure accountable file system that resides over an untrusted storage. SAFIUS provides strong security guarantees like confidentiality, integrity, prevention from rollback attacks, and accountability. SAFIUS also enables read/write sharing of data and provides the standard UNIX-like interface for applications. To achieve accountability with good performance, it uses asynchronous signatures; to reduce the space required for storing these signatures, a novel signature pruning mechanism is used. SAFIUS has been implemented on a GNU/Linux based system modifying OpenGFS. Preliminary performance studies show that SAFIUS has a tolerable overhead for providing secure storage: while it has an overhead of about 50% of OpenGFS in data intensive workloads (due to the overhead of performing encryption/decryption in software), it is comparable (or better in some cases) to OpenGFS in metadata intensive workloads.

description: We study possible superconducting states in transition metal dichalcogenide (TMD) monolayers, assuming an on-site pairing potential that includes both intra- and inter-orbital terms. We find that if the mirror symmetry with respect to the system's plane is broken (e.g., by a substrate), this type of pairing can give rise to unconventional superconductivity, including time-reversal-invariant nodal and fully gapped topological phases. Using a multi-orbital renormalization group procedure, we show how these phases may result from the interplay between the local Coulomb repulsion, Hund's rule coupling, and phonon-mediated attraction. In particular, for a range of interaction parameters, the system transitions from a trivial phase to a nodal phase and finally to a gapped topological phase upon increasing the strength of the mirror symmetry breaking term.

description: We investigate the potential of the Square Kilometer Array Telescope (SKA) to constrain the sound speed of dark energy. The Integrated Sachs Wolfe (ISW) effect results in a significant power spectrum signal when CMB temperature anisotropies are cross-correlated with galaxies detectable with the SKA in HI. We consider using this measurement, the autocorrelation of HI galaxies and the CMB temperature power spectrum to derive constraints on the sound speed. We study the contributions to the cross-correlation signal made by galaxies at different redshifts and use redshift tomography to improve the signal-to-noise. We use a chi-square analysis to estimate the significance of detecting a sound speed different from that expected in quintessence models, finding that there is potential to distinguish very low sound speeds from the quintessence value.

description: Η παρουσία σωματικών συμπτωμάτων χωρίς οργανική βάση είναι ένα συχνό φαινόμενο στα παιδιά και στους εφήβους. Στοιχεία από τη διεθνή βιβλιογραφία δείχνουν ότι η παρουσία των ψυχοσωματικών συμπτωμάτων αυτών σχετίζεται με διάφορους παράγοντες. Σκοπός της παρούσας εργασίας είναι η διερεύνηση της σχέσης μεταξύ των ψυχοσωματικών συμπτωμάτων και δημογραφικών, οικονομικών και ψυχοκοινωνικών παραγόντων. Η έρευνα αφορούσε 475 παιδιά ηλικίας 6-12 ετών. Η μέθοδος συλλογής δεδομένων ήταν ερωτηματολόγια, τα οποία συμπληρώθηκαν μέσω διαδικτύου από γονείς. Τα εργαλεία που χρησιμοποιήθηκαν ήταν λίστες αυτο-αναφοράς για κοινωνικοοικονομικά δεδομένα της οικογένειας και λίστες που αφορούσαν την παρουσία συμπτωμάτων στα παιδιά και στους ίδιους τους γονείς, την ψυχική σταθερότητα και το σχολικό στρες των παιδιών. Διαπιστώθηκε η ύπαρξη σχέσης μεταξύ ορισμένων συμπτωμάτων και της ηλικίας των παιδιών. Αυξημένα ποσοστά κάποιων εκ των συμπτωμάτων βρέθηκαν να σχετίζονται με οικονομικούς παράγοντες : οικογενειακό εισόδημα, παρουσία οικονομικών δυσκολιών, επαγγελματική κατάσταση πατέρα. Βρέθηκαν σημαντικές συσχετίσεις των ψυχοσωματικών συμπτωμάτων των παιδιών με την ψυχική σταθερότητα, το σχολικό στρες και το σχολικό εκφοβισμό. Βρέθηκε, ακόμη, σχέση μεταξύ ψυχοσωματικών συμπτωμάτων γονέων και παιδιών.
description: The presence of physical symptoms without an organic basis is a common phenomenon in children and adolescents. Evidence from the international literature shows that the presence of these psychosomatic symptoms is related to various factors. The purpose of this study is to investigate the relationship between psychosomatic symptoms and demographic, financial and psychosocial factors. The research concerned 475 children aged 6-12 years. The method of data collection was questionnaires, which were completed online by parents. The tools used were self-report lists for socioeconomic data of the family and lists related to the presence of symptoms in children and the parents themselves, mental stability and school stress of children. It was found that there is a relationship between certain symptoms and the age of children. Elevated rates of some of the symptoms were found to be related to financial factors: family income, presence of financial difficulties, professional status of father. Significant correlations were found between children's psychosomatic symptoms and mental stability, school stress and school bullying. A link was also found between psychosomatic symptoms of parents and children.

description: The purpose of the dissertation was to study time series. We examined the characteristics of a time series. Then we looked at the techniques used to predict future events. Furthermore we looked at techniques used to filter a time series and examined how these techniques actually work. Then we studied artificial neural networks, the architectures that have been developed and investigated how they can be applied to our specific problem. We then developed a model that combines artificial neural networks with time series smoothing methods and compared its performance with existing forecasting techniques.

description: Machine learning methods for solving nonlinear partial differential equations (PDEs) are hot topical issues, and different algorithms proposed in the literature show efficient numerical approximation in high dimension. In this paper, we introduce a class of PDEs that are invariant to permutations, and called symmetric PDEs. Such problems are widespread, ranging from cosmology to quantum mechanics, and option pricing/hedging in multi-asset market with exchangeable payoff. Our main application comes actually from the particles approximation of mean-field control problems. We design deep learning algorithms based on certain types of neural networks, named PointNet and DeepSet (and their associated derivative networks), for computing simultaneously an approximation of the solution and its gradient to symmetric PDEs. We illustrate the performance and accuracy of the PointNet/DeepSet networks compared to classical feedforward ones, and provide several numerical results of our algorithm for the examples of a mean-field systemic risk, mean-variance problem and a min/max linear quadratic McKean-Vlasov control problem.

description: The candidate chiral doublet bands recently observed in $^{126}$Cs have been extended to higher spins, several new linking transitions between the two partner members of the chiral doublet bands are observed, and $γ$$-$intensities related to the chiral doublet bands are presented by analyzing the $γ$$-$$γ$ coincidence data collected earlier at the NORDBALL through the $^{116}$Cd$($$^{14}$N, 4n$)$$^{126}$Cs reaction at a beam energy of 65 MeV. The intraband $B(M1)/B(E2)$ and interband $B(M1)_{in}/B(M1)_{out}$ ratios and the energy staggering parameter, S(I), have been deduced for these doublet bands. The results are found to be consistent with the chiral interpretation for the two structures. Furthermore, the observation of chiral doublet bands in $^{126}$Cs together with those in $^{124}$Cs, $^{128}$Cs, $^{130}$Cs and $^{132}$Cs also indicates that the chiral conditions do not change rapidly with decreasing neutron number in these odd-odd Cesium isotopes.

Charge-exchange reaction cross sections and the Gamow-Teller strength for double beta decay

description: The proportionality between single charge-exchange reaction cross sections in the forward direction as found, for example from $(p,n)$ and $(^3$He,$t)$ and from $(n,p)$ and $(d,^2$He) reactions, and the Gamow-Teller (GT) strength into the same final nuclear states has been studied and/or assumed often in the past. Using the most physically justified theory we have at our disposal and for the specific example of the ${}^{76}$Ge-${}^{76}$Se system that may undergo double beta-decay, we demonstrate that the proportionality is a relative good assumption for reactions changing a neutron into a proton, i.e. ${}^{76}$Ge$(p,n){}^{76}$As. In this channel, the main contribution to the GT strengths comes from the removal of a neutron from an occupied single-particle (SP) state and putting a proton into an unoccupied SP state having either the same state quantum numbers or those of the spin-orbit partner. In contrast to this, in the second leg of the double beta decay a single proton must be taken from an occupied SP state and a neutron placed in an unoccupied one. This second process often is Pauli forbidden in medium-heavy nuclei and only can be effected if the Fermi surface is smeared out. Such is the case for ${}^{76}$Se$(n,p){}^{76}$As. Our results suggest that one may not always assume a proportionality between the forward-angle cross sections of the charge-exchange reactions and the GT strength in any such medium-heavy nuclei. The discrepancy originates from a pronounced effect of the radial dependence of the nucleon-nucleon ($NN$) interaction in connection with the Pauli principle on the cross sections in the $(n,p)$ reaction channel. Such a radial dependence is completely absent in the GT transition operator.

description: We study the diffusion properties of the strongly interacting quark-gluon plasma (sQGP) and evaluate the diffusion coefficient matrix for the baryon ($B$), strange ($S$) and electric ($Q$) charges - $κ_{qq'}$ ($q,q' = B, S, Q$) and show their dependence on temperature $T$ and baryon chemical potential $μ_B$. The non-perturbative nature of the sQGP is evaluated within the Dynamical Quasi-Particle Model (DQPM) which is matched to reproduce the equation of state of the partonic matter above the deconfinement temperature $T_c$ from lattice QCD. The calculation of diffusion coefficients is based on two methods: i) the Chapman-Enskog method for the linearized Boltzmann equation, which allows to explore non-equilibrium corrections for the phase-space distribution function in leading order of the Knudsen numbers as well as ii) the relaxation time approximation (RTA). In this work we explore the differences between the two methods. We find a good agreement with the available lattice QCD data in case of the electric charge diffusion coefficient (or electric conductivity) at vanishing baryon chemical potential as well as a qualitative agreement with the recent predictions from the holographic approach for all diagonal components of the diffusion coefficient matrix. The knowledge of the diffusion coefficient matrix is also of special interest for more accurate hydrodynamic simulations.

Deformation modes of an oil-water interface under a local electric field: From Taylor cones to surface dimples

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: Fluidic interfaces disintegrate under sufficiently strong electric fields, leading to electrohydrodynamic (EHD) tip streaming. Taylor cones, which emit charged droplets from the tip of a conical cusp, are among the most prominent and well-studied examples of EHD instabilities. In liquid-liquid systems, more complex interface deformation modes than simple Taylor cones can be observed, with the interface being pushed away from the electrode, and additional cone structures emerging from the rim of the dimple. In this article, we investigate the mechanisms behind these deformation modes experimentally and numerically, and demonstrate that the presence of droplets triggers the dimple at the interface. In order to characterize the underlying processes, we replace the pin electrode by a hollow metallic needle with a prescribed electrolyte volume flow. The submerged electrospray introduces droplets of an aqueous KCl solution with varying ion concentrations into silicone oils with varying viscosities. By measuring the corresponding electric current and by optical investigation of the interface deformation, we study the system response to variations of the ionic concentration, viscosity, applied voltage as well as flow rate. In addition to the experiments, we use a finite element solver and compute the charge transport due to the droplets in the oil phase. Further, we compute the electric potential distribution, flow field and interface deformation. After calibration of our model with particle tracking velocimetry data of the flow inside the oil phase, we reproduce the experimentally observed dimple at the liquid-liquid interface. In summary, this work highlights the importance of charged droplets for the complex dynamic modes observed when a liquid-liquid interface is exposed to a local electric field.

description: We reproduce the expansion velocity--radius ($V_{\rm{exp}}$--$R_{\rm{n}}$) relation in planetary nebulae by considering a simple dynamical model, in order to investigate the dynamical evolution and formation of planetary nebulae. In our model, the planetary nebula is formed and evolving by interaction of a fast wind from the central star with a slow wind from its progenitor, the AGB star. In particular, taking account of the mass loss history of the AGB star makes us succeed in the reproduction of the observed $V_{\rm{exp}}$-$R_{\rm{n}}$ sequence. As a result, examining the ensemble of the observational and theoretical evolution models of PNe, we find that if the AGB star pulsates and its mass loss rate changes with time (from $\sim 10^{-6.4}M_{\odot}$ yr$^{-1}$ to $\sim 10^{-5}M_{\odot}$ yr$^{-1}$), the model agrees with the observations. In terms of observation, we suggest that there are few planetary nebulae with larger expansion velocity and smaller radius because the evolutionary time-scale of such nebulae is so short and the size of nebulae is so compact that it is difficult for us to observe them.

One-loop multicollinear limits from 2-point amplitudes on self-dual backgrounds

description: For scattering amplitudes in strong background fields, it is -- at least in principle -- possible to perturbatively expand the background to obtain higher-point vacuum amplitudes. In the case of self-dual plane wave backgrounds we consider this expansion for two-point, one-loop amplitudes in pure Yang-Mills, QED and QCD. This enables us to obtain multicollinear limits of 1-loop vacuum amplitudes; the resulting helicity configurations are surprisingly restricted, with only the all-plus helicity amplitude surviving. These results are shown to be consistent with well-known vacuum amplitudes. We also show that for both abelian and non-abelian supersymmetric gauge theories, there is no helicity flip (and hence no vacuum birefringence) on any plane wave background, generalising a result previously known in the Euler-Heisenberg limit of super-QED.

Cosmological evolution of the AGN Kinetic Luminosity Function

Publisher: name: arXiv
Year: 2006

description: We present a first attempt to derive the cosmological evolution of the kinetic luminosity function of AGN based on the joint evolution of the flat spectrum radio and hard X-ray selected AGN luminosity functions. An empirical correlation between jet power and radio core luminosity is found, which is consistent with the theoretical assumption that, below a certain Eddington ratio, SMBH accrete in a radiatively inefficient way, while most of the energy output is in the form of kinetic energy. We show how the redshift evolution of the kinetic power density from such a low-mdot mode of accretion makes it a good candidate to explain the so-called ``radio mode'' of AGN feedback as postulated in many galaxy formation schemes.

description: Clinical 12-lead electrocardiography (ECG) is one of the most widely encountered kinds of biosignals. Despite the increased availability of public ECG datasets, label scarcity remains a central challenge in the field. Self-supervised learning represents a promising way to alleviate this issue. In this work, we put forward the first comprehensive assessment of self-supervised representation learning from clinical 12-lead ECG data. To this end, we adapt state-of-the-art self-supervised methods based on instance discrimination and latent forecasting to the ECG domain. In a first step, we learn contrastive representations and evaluate their quality based on linear evaluation performance on a recently established, comprehensive, clinical ECG classification task. In a second step, we analyze the impact of self-supervised pretraining on finetuned ECG classifiers as compared to purely supervised performance. For the best-performing method, an adaptation of contrastive predictive coding, we find a linear evaluation performance only 0.5% below supervised performance. For the finetuned models, we find improvements in downstream performance of roughly 1% compared to supervised performance, label efficiency, as well as robustness against physiological noise. This work clearly establishes the feasibility of extracting discriminative representations from ECG data via self-supervised learning and the numerous advantages when finetuning such representations on downstream tasks as compared to purely supervised training. As first comprehensive assessment of its kind in the ECG domain carried out exclusively on publicly available datasets, we hope to establish a first step towards reproducible progress in the rapidly evolving field of representation learning for biosignals.

description: We report the first realization of a guided quasicontinuous atom laser by rf outcoupling a Bose-Einstein condensate from a hybrid optomagnetic trap into a horizontal atomic waveguide. This configuration allows us to cancel the acceleration due to gravity and keep the de Broglie wavelength constant at 0.5 $μ$m during 0.1 s of propagation. We also show that our configuration, equivalent to pigtailing an optical fiber to a (photon) semiconductor laser, ensures an intrinsically good transverse mode matching.

Effects of non-standard interactions in the MINOS experiment

description: We investigate the effects of non-standard interactions on the determination of the neutrino oscillation parameters $Δm_{31}^2$, $θ_{23}$, and $θ_{13}$ in the MINOS experiment. We show that adding non-standard interactions to the analysis leads to an extension of the allowed parameter space to larger values of $Δm_{31}^2$ and smaller $θ_{23}$, and basically removes all predictability for $θ_{13}$. In addition, we discuss the sensitivities to the non-standard interaction parameters of the MINOS experiment alone. In particular, we examine the degeneracy between $θ_{13}$ and the non-standard interaction parameter $\eps_{eτ}$. We find that this degeneracy is responsible for the removal of the $θ_{13}$ predictability and that the possible bound on $|\eps_{eτ}|$ is competitive with direct bounds only if a more stringent external bound on $θ_{13}$ is applied.

description: In clinical practice, medical image interpretation often involves multi-labeled classification, since the affected parts of a patient tend to present multiple symptoms or comorbidities. Recently, deep learning based frameworks have attained expert-level performance on medical image interpretation, which can be attributed partially to large amounts of accurate annotations. However, manually annotating massive amounts of medical images is impractical, while automatic annotation is fast but imprecise (possibly introducing corrupted labels). In this work, we propose a new regularization approach, called Flow-Mixup, for multi-labeled medical image classification with corrupted labels. Flow-Mixup guides the models to capture robust features for each abnormality, thus helping handle corrupted labels effectively and making it possible to apply automatic annotation. Specifically, Flow-Mixup decouples the extracted features by adding constraints to the hidden states of the models. Also, Flow-Mixup is more stable and effective comparing to other known regularization methods, as shown by theoretical and empirical analyses. Experiments on two electrocardiogram datasets and a chest X-ray dataset containing corrupted labels verify that Flow-Mixup is effective and insensitive to corrupted labels.
Evidence for a Transverse Single-Spin Asymmetry in Leptoproduction of pi+pi- Pairs

description: A single-spin asymmetry was measured in the azimuthal distribution of pi+pi- pairs produced in semi-inclusive deep-inelastic scattering on a transversely polarized hydrogen target. For the first time, evidence is found for a correlation between the transverse target polarization and the azimuthal orientation of the plane containing the two pions.The corresponding single-spin asymmetry is expected to be related to the product of the little-known quark transversity distribution function and an unknown naive-T-odd chiral-odd dihadron fragmentation function.

description: Electroencephalography (EEG) has countless applications across many of fields. However, EEG applications are limited by low signal-to-noise ratios. Multiple types of artifacts contribute to the noisiness of EEG, and many techniques have been proposed to detect and correct these artifacts. These techniques range from simply detecting and rejecting artifact ridden segments, to extracting the noise component from the EEG signal. In this paper we review a variety of recent and classical techniques for EEG data artifact detection and correction with a focus on the last half-decade. We compare the strengths and weaknesses of the approaches and conclude with proposed future directions for the field.
