description: We present a new scheme for performing optical spectroscopy on single molecules. A glass capillary with a diameter of 600 nm filled with an organic crystal tightly guides the excitation light and provides a maximum spontaneous emission coupling factor ($β$) of 18% for the dye molecules doped in the organic crystal. Combination of extinction, fluorescence excitation and resonance fluorescence spectroscopy with microscopy provides high-resolution spatio-spectral access to a very large number of single molecules in a linear geometry. We discuss strategies for exploring a range of quantum optical phenomena, including coherent cooperative interactions in a mesoscopic ensemble of molecules mediated by a single mode of propagating photons.

description: It has always been a severe loss for any establishment when an experienced hand retires or moves to another firm. The specific details of what his job/position entails will always make the work more efficient. To curtail such losses, it is possible to implement a system that takes input from a new employee regarding the challenges he/she is facing and match it to a previous occurrence where someone else held his/her chair. This system could be made possible with input through the ages from the array of individuals who managed that particular job and processing this data through a neural network that recognizes the pattern. The paper is based on data collected from traditional wooden dhow builders and some of the modern day unconventional shipyards. Since the requirements for successful implementation in such scenarios seems too steep at the moment, an alternate approach has been suggested by implementation through the design processes across multiple shipyards. The process entails the traditional value passed down through generations regarding a particular profession and analysis has been done regarding how this knowledge/experience can be captured and preserved for future generations to work upon. A series of tools including SharePoint, MATLAB, and some similar software working in tandem can be used for the design of the same. This research will provide valuable insight as to how information sharing can be applied through generations for effective application of production capabilities.

description: Показывается, что форма и содержание принципов налогообложения могут оказывать негативное воздействие на формирование и развитие российской налоговой системы и проводимую государством налоговую политику. В качестве методологической основы анализа используется системный анализ положений налогового законодательства, метод сопоставления взглядов российских и зарубежных авторов на систему принципов налогообложения. Предметом исследования является система принципов, оказывающих воздействие на формирование налоговой системы и проводимую государством налоговую политику. Новизна исследования заключается в комплексном рассмотрении теоретических и практических вопросов системы принципов налогообложения, теоретическом обосновании необходимости внесения поправок в действующее налоговое законодательство в данной области. Доказывается необходимость закрепления в российском налоговом законодательстве принципов налогообложения путем введения в Налоговый кодекс Российской Федерации специальной главы о принципах, которые должны быть заложены в формирование и развитие российской налоговой системы. Особым вкладом автора являются рекомендации по структуре предлагаемого раздела Кодекса, а также о составе и видах современных принципов налогообложения.It is demonstrated that the form and content of tax principles may have a negative effect on the formation and development of Russia's tax system and tax policy. The methodological basis for analysis involves systems analysis of the provisions of laws and comparison of views of Russian and foreign researchers on the taxation principles system. The subject of the research is the system of principles that influence the development of the tax system and tax policy of the state. The novelty of the research is caused by the fact that the author carries out a comprehensive analysis of theoretical and practical issues related to the system of taxation principles as well as offers a theoretical substantiation of the need to make amendments to the current tax laws in this sphere. The author proves the need to fix principles of taxation in Russia's tax laws by adding a special chapter that would describe principles formation and development of Russia's tax system should be based upon. The author's special contribution is his recommendations concerning the structure of the section that he suggests to add to the Tax Code as well as description of the contents and types of modern principles of taxation.

description: A geometric progression of length $k$ and integer ratio is a set of numbers of the form $\{a,ar,\dots,ar^{k-1}\}$ for some positive real number $a$ and integer $r\geq 2$. For each integer $k \geq 3$, a greedy algorithm is used to construct a strictly decreasing sequence $(a_i)_{i=1}^{\infty}$ of positive real numbers with $a_1 = 1$ such that the set \[ G^{(k)} = \bigcup_{i=1}^{\infty} \left(a_{2i} , a_{2i-1} \right] \] contains no geometric progression of length $k$ and integer ratio. Moreover, $G^{(k)}$ is a maximal subset of $(0,1]$ that contains no geometric progression of length $k$ and integer ratio. It is also proved that there is a strictly increasing sequence $(A_i)_{i=1}^{\infty}$ of positive integers with $A_1 = 1$ such that $a_i = 1/A_i$ for all $i = 1,2,3,\ldots$. The set $G^{(k)}$ gives a new lower bound for the maximum cardinality of a subset of the set of integers $\{1,2,\dots,n\}$ that contains no geometric progression of length $k$ and integer ratio.

description: We calculate the one-photon exchange contribution to the interatomic interaction potential between electrically neutral, identical atoms, one of which is assumed to be in an excited state, by matching the scattering matrix (S matrix) element with the effective Hamiltonian. This approach allows us to use covariant perturbation theory, where the two possible time orderings of emission and absorption are summarized in a single Feynman amplitude. Our results encompass the full retardation correction to the one-photon exchange van-der-Waals potential. We employ the temporal gauge for the virtual photon propagator. Based on the Feynman prescription, we obtain the imaginary part of the interaction energy, which leads to an interaction-induced correction to the decay rate. Our results lead to precise formulas for the distance-dependent enhancement and suppression of the decay rates of entangled superradiant and subradiant Dicke state, as a function of the interatomic distance. We apply the result to an example calculation involving two hydrogen atoms, one of which is in the ground state, the other in an excited P state.

description: In this paper the system of field equations governing the one-dimensional magnetoelastic evolution in a ferromagnet, which is immersed in an electromagnetic field and subjected to mechanical loads at a constant temperature below the Curie point, is considered. It is assumed that displacement currents are negligible and that all field quantities depend on one space variable only. The hysteretic relation between the applied magnetic field and the magnetization in the ferromagnet are modeled using the notion of hysteresis operators; in particular, hysteresis operators of Preisach type are included. It is shown that an initial-boundary value problem for the system admits global solutions for arbitrary initial data, if viscosity is present in the material, and for small initial data, if not. The considered field equations may be regarded as a model for the effect of magnetostriction in ferromagnets.

description: Among silicon-based solar cells, heterojunction cells hold the world efficiency record. However, their market acceptance is hindered by an initial 0.5\% per year degradation of their open circuit voltage which doubles the overall cell degradation rate. Here, we study the performance degradation of crystalline-Si/amorphous-Si:H heterojunction stacks. First, we experimentally measure the interface defect density over a year, the primary driver of the degradation. Second, we develop SolDeg, a multiscale, hierarchical simulator to analyze this degradation by combining Machine Learning, Molecular Dynamics, Density Functional Theory, and Nudged Elastic Band methods with analytical modeling. We discover that the chemical potential for mobile hydrogen develops a gradient, forcing the hydrogen to drift from the interface, leaving behind recombination-active defects. We find quantitative correspondence between the calculated and experimentally determined defect generation dynamics. Finally, we propose a reversed Si-density gradient architecture for the amorphous-Si:H layer that promises to reduce the initial open circuit voltage degradation from 0.5\% per year to 0.1\% per year.

description: A novel, learning-based method for in situ estimation of soil properties using a physics-infused neural network (PINN) is presented. The network is trained to produce estimates of soil cohesion, angle of internal friction, soil-tool friction, soil failure angle, and residual depth of cut which are then passed through an earthmoving model based on the fundamental equation of earthmoving (FEE) to produce an estimated force. The network ingests a short history of kinematic observations along with past control commands and predicts interaction forces accurately with average error of less than 2kN, 13% of the measured force. To validate the approach, an earthmoving simulation of a bladed vehicle is developed using Vortex Studio, enabling comparison of the estimated parameters to pseudo-ground-truth values which is challenging in real-world experiments. The proposed approach is shown to enable accurate estimation of interaction forces and produces meaningful parameter estimates even when the model and the environmental physics deviate substantially.

description: We present a study by ferromagnetic resonance at microwave Q band of two sheets of cobalt nanoparticles obtained by annealing SiO2 layers implanted with cobalt ions. This ex- perimental study is performed as a function of the applied magnetic field orientation, tempera- ture, and dose of implanted cobalt ions. We demonstrate that each of those magnetic sheet of cobalt nanoparticles can be well modelled by a nearly two dimensional ferromagnetic sheet hav- ing a reduced effective saturation magnetization, compared to a regular thin film of cobalt. The nanoparticles are found superparamagnetic above around 210 K and ferromagnetic below this blocking temperature. Magnetostatic calculations show that a strong magnetic field gradient of around 0.1 G/nm could be produced by a ferromagnetic nanostripe patterned in such magnetic sheet of cobalt nanoparticles. Such a strong magnetic field gradient combined with electron para- magnetic resonance may be relevant for implementing an intermediate scale quantum computer based on arrays of coupled electron spins, as previously reported (Eur. Phys. J. B (2014) 87, 183). However, this new approach only works if no additional spin decoherence is introduced by the spin waves exitations of the ferromagnetic nanostructure. We thus suggest theoretically some possible magnetic anisotropy engineering of cobalt nanoparticles that could allow to suppress the spin qubit decoherence induced by the unwanted collective excitation of their spins.

description: Accurate identification of emphysema subtypes and severity is crucial for effective management of COPD and the study of disease heterogeneity. Manual analysis of emphysema subtypes and severity is laborious and subjective. To address this challenge, we present a deep learning-based approach for automating the Fleischner Society's visual score system for emphysema subtyping and severity analysis. We trained and evaluated our algorithm using 9650 subjects from the COPDGene study. Our algorithm achieved the predictive accuracy at 52\%, outperforming a previously published method's accuracy of 45\%. In addition, the agreement between the predicted scores of our method and the visual scores was good, where the previous method obtained only moderate agreement. Our approach employs a regression training strategy to generate categorical labels while simultaneously producing high-resolution localized activation maps for visualizing the network predictions. By leveraging these dense activation maps, our method possesses the capability to compute the percentage of emphysema involvement per lung in addition to categorical severity scores. Furthermore, the proposed method extends its predictive capabilities beyond centrilobular emphysema to include paraseptal emphysema subtypes.

description: (Abridged) We aim at identifying the least massive population of the solar metallicity, young (120 Myr), nearby (133.5 pc) Pleiades star cluster with the ultimate goal of understanding the physical properties of intermediate-age, free-floating, low-mass brown dwarfs and giant planetary-mass objects, and deriving the cluster substellar mass function across the deuterium-burning mass limit at ~0.012 Msol. We performed a deep photometric and astrometric J- and H-band survey covering an area of ~0.8 deg^2. The images with completeness and limiting magnitudes of J,H ~ 20.2 and ~ 21.5 mag were acquired ~9 yr apart (proper motion precision of +/-6 mas/yr). J- and H-band data were complemented with Z, K, and mid-infrared magnitudes up to 4.6 micron coming from UKIDSS, WISE, and follow-up observations of our own. Pleiades member candidates were selected to have proper motions compatible with that of the cluster, and colors following the known Pleiades sequence in the interval J = 15.5-8.8 mag, and Z_UKIDSS - J > 2.3 mag or Z nondetections for J > 18.8 mag. We found a neat sequence of astrometric and photometric Pleiades substellar member candidates in the intervals J = 15.5-21.2 mag and ~0.072-0.008 Msol. The faintest objects show very red near- and mid-infrared colors exceeding those of field high-gravity dwarfs by >0.5 mag. The Pleiades photometric sequence does not show any color turn-over because of the presence of photospheric methane absorption down to J = 20.3 mag, which is about 1 mag fainter than predicted by the color-computed models. Pleiades brown dwarfs have a proper motion dispersion of 6.4-7.5 mas/yr and are dynamically relaxed at the age of the cluster. The Pleiades mass function extends down to the deuterium burning-mass threshold, with a slope fairly similar to that of other young star clusters and stellar associations.

description: The use of ventricular assist devices has expanded significantly since their approval by the Food and Drug Administration in the United States in 1994. In addition to this, the prevalence of heart failure continues to increase. We aim to provide an overview of perioperative considerations and management of these patients for non-cardiac surgery. We performed a Medline search for the words "ventricular assist device," "Heartmate" and "HeartWare" to gain an overview of the literature surrounding these devices, and chose studies with relevance to the stated aims of this review. Patients with ventricular assist devices are presenting more frequently for surgery not related to their cardiac pathology. As the mechanically supported population grows, general anesthesiologists will be faced with managing these patients, possibly outside of the tertiary care setting. The unique challenges of this patient population can best be addressed by a thorough understanding of ventricular assist device physiology and a multidisciplinary approach to care.

description: It is well-known that multivariate curve estimation suffers from the "curse of dimensionality". However, reasonable estimators are possible, even in several dimensions, under appropriate restrictions on the complexity of the curve. In the present paper we explore how much appropriate wavelet estimators can exploit typical restrictions on the curve, which require a local adaptation to different degrees of smoothness in the different directions. It turns out that the application of a anisotropic multivariate basis, which has in contrast to the conventional multivariate resolution scheme a multidimensional scale parameter, is essential. Some simulations indicate the possible gains by this new method over thresholded estimators based on the multiresolution basis with a one-dimensional scale index.

description: We analyse the low temperature phase of ferromagnetic Kac-Ising models in dimensions d ≥ 2. We show that if the range of interactions is γ-1, then two disjoint translation invariant Gibbs states exist, if the inverse temperature β satisfies β - 1 ≥ γκ, where κ = d(1-ε) ⁄ (2d+2)(d+1), for any ε > 0. The prove involves the blocking procedure usual for Kac models and also a contour representation for the resulting long-range (almost) continuous spin system which is suitable for the use of a variant of the Peierls argument.

description: Asthma affects 1 in 12 children in the U.S. and has shown to affect a child’s peer functioning and academic achievement (Bloomberg et al., 2009; CDC, 2018; Graetz & Shute, 1995; Moonie et al., 2008; Schmier et al., 2007). The sample consists of 58 caregivers of children with asthma ages 5 to 17 and is primarily low-income, ethnically, and racially diverse. The study examines the correlations between asthma control, academic performance, school absenteeism, and peer functioning, and examines the mediational role of school absenteeism in these relationships. Results show that poorer asthma control was associated with higher school absenteeism. Both, poorer asthma control and higher school absenteeism, were also associated with lower GPA. Poorly controlled asthma can impact a child’s overall functioning in school, which may have long-term effects on future educational attainment.

description: EU data protection rules could be difficult for researchers to navigate, particularly when processing massive datasets containing personal data for Artificial Intelligence (AI) developments. This article examines how data protection intersects with AI research to elucidate the issues arising from the use of large-scale databases containing personal data to train, test and validate AI systems. The key objectives of this work are to (1) scrutinise the data protection requirements and limits for the processing of personal data in AI research, (2) reflect on possible complications regarding data quality requirements for trustworthy AI and General Data Protection Regulation (GDPR) compliance, and (3) present possible ways forward to reconcile GDPR requirements and AI research. While reviewing and mapping relevant provisions and guidance, we identify data protection challenges posed by the use of massive databases containing personal data for AI research. The findings suggest that, while the legal regime for research under the GDPR resolves some of the challenges identified, others, such as legal basis for processing and processing of special categories of data, remain unaddressed. We argue that the nature of these complications will make it difficult for EU researchers to advance in trustworthy AI efforts. The analysis concludes by suggesting possible ways to tackle the remaining issues.

description: The present lecture deals with the development of new normalization procedures and averaging algorithms in problems of nonlinear vibrations. Namely, the development of asymptotic methods of perturbation theory is considered, making wide use of group theoretical techniques. Various assumptions about specific group properties are investigated, and are shown to lead to modifications of existing methods, such as the Bogoliubov averaging method and the Poincaré-Birkhoff normal form, as well as to the formulation of new ones. The development of normalization techniques on Lie groups is also treated.

description: A lot of works has been devoted to stability analysis of a stationary point for linear and non-linear systems of stochastic differential equations. Here we consider the stability of an invariant compact manifold of a non-linear system. To this end we derive a linearized system for orthogonal displacements of a solution from the manifold. For this system, we introduce notions of Lyapunov exponents, moment Lyapunov exponents, and stability index. The stability index controls the asymptotic behavior of solutions of the input system in a neighborhood of the manifold. Most extensively we study these problems in the case when the invariant manifold is an orbit.

description: We prove the long-standing Eckmann-Ruelle conjecture in dimension theory of smooth dynamical systems. Namely, we show that the pointwise dimension exists almost everywhere with respect to a Borel probability measure with non-zero Lyapunov exponents invariant under a C1+α diffeomorphism of a smooth Riemannian manifold. This implies in particular that the Hausdorff dimension and box dimension of the measure as well as some other characteristics of dimension type of the measure coincide.

description: Σκοπός της παρούσας έρευνας ήταν να εξετάσει την αποτελεσματικότητα ενός προγράμματος διδασκαλίας δεξιοτήτων ζωής στο μάθημα της φυσικής αγωγής και την επίδρασή του στην επίδοση των μαθητών / τριών σε δοκιμασίες δύναμης και ευλυγισίας και στον αυτοκαθορισμό τους. Στην έρευνα συμμετείχαν 73 μαθητές / τριες Α' γυμνασίου οι οποίοι χωρίστηκαν στην αρχική πειραματική ομάδα {η = 35) και στην αρχική ομάδα ελέγχου (η = 38). Μετά την εφαρμογή του προγράμματος παρέμβασης στην αρχική πειραματική ομάδα, έγινε αντιστροφή των ομάδων και το ίδιο πρόγραμμα εφαρμόστηκε στην αρχική ομάδα ελέγχου. Το πρόγραμμα παρέμβασης περιλάμβανε τις δεξιότητες του καθορισμού στόχων και της θετικής σκέψης - αυτοομιλίας, αποτελούνταν από 8 μαθήματα και συνδυάστηκε με ένα πρόγραμμα για την ανάπτυξη της φυσικής κατάστασης των μαθητών / τριών. Για τη μέτρηση της δύναμης χρησιμοποιήθηκε η δοκιμασία «κάμψεις με στήριξη στα γόνατα», ενώ για την ευλυγισία η δοκιμασία «δίπλωση από εδραία θέση» (Safrit, 1995). Για τον αυτοκαθορισμό χρησιμοποιήθηκε το ερωτηματολόγιο του αυτοκαθορισμού στη φυσική αγωγή (Goudas, Dermitzaki & Bagiatis, 2000). Μετά το τέλος της παρέμβασης πραγματοποιήθηκαν συνεντεύξεις από 16 μαθητές / τριες. Η ανάλυση των αποτελεσμάτων έδειξε ότι το πρόγραμμα παρέμβασης της διδασκαλίας των δεξιοτήτων ζωής ήταν αποτελεσματικό καθώς συνέβαλε στην αύξηση της επίδοσης των μαθητών / τριών στις δοκιμασίες της δύναμης και της ευλυγισίας και στις δύο φάσεις της έρευνας. Από την άλλη πλευρά ο αυτοκαθορισμός των μαθητών / τριών που διδάχθηκαν τις δεξιότητες ζωής δεν αυξήθηκε σημαντικά σε σύγκριση με τους μαθητές της ομάδας ελέγχου αλλά μόνο σε σύγκριση με τα αρχικά επίπεδα πριν την παρέμβαση σε κάθε φάση της έρευνας. Η ανάλυση των συνεντεύξεων έδειξε ότι οι μαθητές / τριες βρήκαν τη διδασκαλία των δεξιοτήτων ζωής ευχάριστη, ενδιαφέρουσα και χρήσιμη, ενώ ανέφεραν ότι χρησιμοποίησαν τις δεξιότητες ζωής σε άλλα μαθήματα, καθώς επίσης και σε δραστηριότητες εκτός του σχολείου. Συμπερασματικά, η δϊΜ^καλίατων δεξιοτήτων ζωής στο μάθημα της φυσικής αγωγής, εκτός του γεγονότος ότι οπλίζει τους μαθητές / τριες με δεξιότητες που μπορούν να χρησιμοποιήσουν και σε άλλους τομείς της ζωής, μπορεί να συμβάλει θετικά και στην επίτευξη των στόχων του μαθήματος.

description: It has been recently shown that probabilistic protocols based on postselection boost the performances of phase estimation and the replication of quantum clocks. Here we demonstrate that the improvements in these two tasks have to match exactly in the macroscopic limit where the number of clones grows to infinity, preserving the equivalence between asymptotic cloning and estimation for arbitrary values of the success probability. Remarkably, the cloning fidelity depends critically on the number of rationally independent eigenvalues of the clock Hamiltonian. We also prove that probabilistic metrology can simulate cloning in the macroscopic limit for arbitrary sets of states, provided that the performance of the simulation is measured by testing small groups of clones.
On the asymptotic analysis of singularly perturbed systems with sliding mode

description: In this paper we study singularly perturbed systems with discontinuity surfaces. This means that we have a system of ordinary differential equations with a small parameter and a piecewise smooth vector field. The state where the trajectory moves on the discontinuity surface is called sliding mode. We present an asymptotic representation for trajectories with temporary sliding and apply the result to stick-slip vibrations.
Instability of localised buckling modes in a one-dimensional strut model

description: Stability of localised equilibria arising in a fourth-order partial differential equation modelling struts is investigated. It was shown in Buffoni, Champneys & Toland (1996) that the model exhibits many multi-modal buckling states bifurcating from a primary buckling mode. In this article, using analytical and numerical techniques, the primary mode is shown to be unstable under dead loading in a large range of parameter values, while is likely to be stable under rigid loading for small axial loads. Furthermore, for general reversible or Hamiltonian systems, stability of the multi-modal solutions is established assuming stability of the primary state. As this hypothesis is not satisfied for the buckling mode arising in the strut model, any multi-modal buckling state will be unstable for both loading devices.
Minimal circuit for a flux-controlled Majorana qubit in a quantum spin-Hall insulator

description: We construct a minimal circuit, based on the top-transmon design, to rotate a qubit formed out of four Majorana zero-modes at the edge of a two-dimensional topological insulator. Unlike braiding operations, generic rotations have no topological protection, but they do allow for a full characterization of the coherence times of the Majorana qubit. The rotation is controlled by variation of the flux through a pair of split Josephson junctions in a Cooper pair box, without any need to adjust gate voltages. The Rabi oscillations of the Majorana qubit can be monitored via oscillations in the resonance frequency of the microwave cavity that encloses the Cooper pair box.

description: Gamma-Ray Bursts (GRBs) are panchromatic, highly energetic transients whose energy emission mechanism is still debated. One of the possible explanations is the standard fireball model, which can be tested with the closure relations (CRs), or relations between the temporal and spectral indices of a GRB. To test these, we compile an extensive sample of radio afterglow light curves (LCs) that span from 1997 to 2020, the most comprehensive analysis of GRBs with radio observations to date. We fit 202 LCs from 82 distinct GRBs with a broken power law, obtaining a sample of 26 that display a clear break and a subsample of 14 GRBs that present a radio plateau. We test these samples against CRs corresponding to a constant-density interstellar medium (ISM) or a stellar wind medium in both fast- and slow-cooling regimes, as well as three additional density profiles, $k = 1, 1.5, 2.5,$ following $n \propto r^{-k}$ , and consider sets of CRs both with and without energy injection. We find that 12 of the 26 GRBs (46%), of which 7/12 present a radio plateau, fulfill at least one CR in the sets tested, suggesting our data is largely incompatible with the standard fireball model. Of the fulfilled CRs, the most preferred environment is the ISM, SC, $ν_m < ν< ν_c$ without energy injection. Our results are consistent with previous studies that test the standard fireball model via the CRs in radio.

description: We consider the individual points on a Martin-Löf random path of Brownian motion. We show (1) that Khintchine's law of the iterated logarithm holds at almost all points; and (2) there exist points (besides the trivial example of the origin) having effective dimension $<1$. The proof of (1) shows that for almost all times $t$, the path $f$ is Martin-Löf random relative to $t$ and so the effective dimension of $(t,f(t))$ is 2.

description: This study aims to determine the research mapping regarding the Net Profit Margin (NPM) ratio in Islamic and Conventional Banking using a mix-method approach, namely the VOSviewer bibliometric study and literature review. Data analysis techniques include: (1) mapping the distribution of journal publications around the NPM ratio; (2) mapping the results of the VOSviewer bibliometric visualization around the NPM ratio based on the number of clusters and their items; and (3) mapping research topics around the NPM ratio using a literature review study. The results showed that: (1) based on the distribution of journal publications, there were 885 journal publications regarding the NPM ratio; (2) based on the mapping of the VOSviewer bibliometric study, the network visualization results around the NPM ratio are divided into 4 clusters and 175 topic items; (3) based on the mapping of literature review studies, there are 49 topics around the influence of the NPM ratio and 41 topics about the determinants of the NPM ratio. The implications and contributions of this research are to map research topics around NPM ratios in Islamic and Conventional Banking which are often or rarely researched by researchers so that they can be a reference for subsequent researchers.
