description: We introduce StockBabble, a conversational agent designed to support understanding and engagement with the stock market. StockBabble's value and novelty is in its ability to empower retail investors -- many of which may be new to investing -- and supplement their informational needs using a user-friendly agent. Users have the ability to query information on companies to retrieve a general and financial overview of a stock, including accessing the latest news and trading recommendations. They can also request charts which contain live prices and technical investment indicators, and add shares to a personal portfolio to allow performance monitoring over time. To evaluate our agent's potential, we conducted a user study with 15 participants. In total, 73% (11/15) of respondents said that they felt more confident in investing after using StockBabble, and all 15 would consider recommending it to others. These results are encouraging and suggest a wider appeal for such agents. Moreover, we believe this research can help to inform the design and development of future intelligent, financial personal assistants.

The organization of microcore technology in the Canadian southern interior plateau
Creators: name: Greaves, Sheila
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this research is to construct and test a model of the organization of microcore technology, a standardized core technology, within the subsistence-settlement system of prehistoric, semi-sedentary hunter-gatherers. The study of technological organization involves investigation of why a society selects particular tool designs, and how it structures the manufacture, use, maintenance and discard of tools and associated debitage across the landscape. The model tested here associates the use of microcore technology with a design for a maintainable and transportable tool assemblage which conserves lithic material, and with a regional distribution focused on residential camps as the locus of microcore manufacture and microblade production and use. The model is tested through a comparative case study of archaeological tools and debitage from microlithic and non-microlithic sites in two upland valleys in the British Columbia Southern Interior Plateau. Research hypotheses and corresponding test implications are evaluated with data and analyses relating to core reduction and tool production stages, to tool use, and to activity area patterning within the sites. Results of hypothesis testing indicate that the model only partially explains the role of this particular standardized core technology in the study areas. Microcore technology is found to be associated with high residential and logistical mobility; a transportable, expediently-used tool assemblage; and the conservation of a specific raw material in one valley. Thus, this research proposes that microcore technology was a standardized technology which was variable in design goals and distribution, even within the same geographically and ethnographically defined region.

description: Η αθηροσκλήρυνση θεωρείται σήμερα ως μια εξελικτική φλεγμονώδης νόσος στην εμφάνιση της οποίας συμμετέχουν γενετικοί και περιβαλλοντικοί παράγοντες. Σκοπός της μελέτης ήταν να ερευνήσουμε εάν σε άτομα με θετικό οικογενειακό ιστορικό πρώϊμης στεφανιαίας νόσου έχει αρχίσει ήδη από την παιδική ηλικία η φλεγμονώδης διαδικασία της αθηροσκλήρυνσης. Εφαρμόσαμε καλλιέργειες μονοκυττάρων του περιφερικού αίματος και μελετήσαμε τη βασική έκκριση ιντερλευκίνης -1, ιντερλευκίνης -6 και TNF-a και μελετήσαμε την πιθανή ενεργοποίηση των αιμοπεταλίων μέσω της β-θροβογλομπουλίνης. Μελετήσαμε 55 παιδιά(5-15 ετών), 30(16 αγόρια) με θετικό οικογενειακό ιστορικό αθηροσκλήρυνσης και 25 μάρτυρες. Σε όλα τα παιδιά μετρήθηακν και οι κλασικοί παράγοντες κινδύνου(αρτηριακή πίεση, ΒΜ1, σάκχαρο κ.α.). Βρέθηκε ότι στα παιδιά με θετικό οικογενειακό ιστορικό υπάρχει αύξηση της έκκρισης προφλεγμονωδών κυτταροκινών. Ισχυρή συσχέτιση με την ενεργοποίηση της φλεγμονής βρέθηκε ότι έχουν ο αθηρωματικός δείκτης, το ΒΜ1, το ΡΑI-1 και κυρίως τα τριγλυκερίδια
description: Atherosclerosis is considered nowdays as a progressive inflammatory disease, the aim of this study was to investigate whether the onset of the inflammatory process of atherogenesis initiates early, in children with positive family history of premature coronary artery disease. We applied monocells cultures from peripheral blood and studied their basal secretion of inflammatory cytokines. The study included 55 children(5-15 years), 30(16 male) with positive family history of atherosclerosis and 25 without (control group). We studed also the other classical risk factors of atherosclerosis(blood pressure, glucose e.a.). We found that the children with positive family history appear to have increased secretion of pro-inflammatory cytokines. A strong relationship between activation of inflammation and atheromatous index, BM1, PAI-1 and triglycerides was also found

description: Graphene is the first example of truly two-dimensional crystals - it's just one layer of carbon atoms. It turns out to be a gapless semiconductor with unique electronic properties resulting from the fact that charge carriers in graphene demonstrate charge-conjugation symmetry between electrons and holes and possess an internal degree of freedom similar to ``chirality'' for ultrarelativistic elementary particles. It provides unexpected bridge between condensed matter physics and quantum electrodynamics (QED). In particular, the relativistic Zitterbewegung leads to the minimum conductivity of order of conductance quantum $e^2/h$ in the limit of zero doping; the concept of Klein paradox (tunneling of relativistic particles) provides an essential insight into electron propagation through potential barriers; vacuum polarization around charge impurities is essential for understanding of high electron mobility in graphene; index theorem explains anomalous quantum Hall effect.

description: We study the decay phase of solar flares in several spectral bands using a method based on that successfully applied to white light flares observed on an M4 dwarf. We selected and processed 102 events detected in the Sun-as-a-star flux obtained with SDO/AIA images in the 1600~Å and 304~Å channels and 54 events detected in the 1700~Å channel. The main criterion for the selection of time profiles was a slow, continuous flux decay without significant new bursts. The obtained averaged time profiles were fitted with analytical templates, using different time intervals, that consisted of a combination of two independent exponents or a broken power law. The average flare profile observed in the 1700~Å channel decayed more slowly than the average flare profile observed on the M4 dwarf. As the 1700~Å emission is associated with a similar temperature to that usually ascribed to M dwarf flares, this implies that the M dwarf flare emission comes from a more dense layer than solar flare emission in the 1700~Å band. The cooling processes in solar flares were best described by the two exponents model, fitted over the intervals t1=[0, 0.5]$t_{1/2}$ and t2=[3, 10]$t_{1/2}$ where $t_{1/2}$ is time taken for the profile to decay to half the maximum value. The broken power law model provided a good fit to the first decay phase, as it was able to account for the impact of chromospheric plasma evaporation, but it did not successfully fit the second decay phase.

description: In a short superconducting nanowire connected to bulk superconducting leads, quantum phase slips behave as a system of linearly (as opposed to logarithmically) interacting charges. This system maps onto quantum mechanics of a particle in a periodic potential. We show that, while the state with a high density of phase slips is not a true insulator (a consequence of Josephson tunneling between the leads), for a range of parameters it behaves as such down to unobservably small temperatures. We also show that quantum phase slips give rise to multiple branches (bands) in the energy-current relation and to an interband ("exciton") mode.

description: The study refers to an oblong family tumulus in the cemetery of Vergina, which is the second in size after the Great Tumulus. It covered 3 graves, a big pit-grave with inhumation in the center and 2 cist-graves of average size on both sides, connected with cremation. The tombs are dated in the mid-4th c. B.C. The tumulus obtained its form gradually, as the separate mounds of earth of each grave were being united. In the study the excavation data of the tumulus are analysed and the tombs and their finds are fully described. Very interesting is the pottery : two categories of hydrial, with polychrome decoration and with white coating and an acorn-lecythos. Masterfully executed are some of the weapons of the tombs. The last part of the study concentrates on the burial customs and their analysis in relation with the tumulus reveals the intention of the family that exposes its power and status in the community and underlines its ties in every way
Data-Driven Threat Hunting Using Sysmon

description: Threat actors can be persistent, motivated and agile, and leverage a diversified and extensive set of tactics and techniques to attain their goals. In response to that, defenders establish threat intelligence programs to stay threat-informed and lower risk. Actionable threat intelligence is integrated into security information and event management systems (SIEM) or is accessed via more dedicated tools like threat intelligence platforms. A threat intelligence platform gives access to contextual threat information by aggregating, processing, correlating, and analyzing real-time data and information from multiple sources, and in many cases, it provides centralized analysis and reporting of an organization's security events. Sysmon logs is a data source that has received considerable attention for endpoint visibility. Approaches for threat detection using Sysmon have been proposed, mainly focusing on search engine technologies like NoSQL database systems. This paper demonstrates one of the many use cases of Sysmon and cyber threat intelligence. In particular, we present a threat assessment system that relies on a cyber threat intelligence ontology to automatically classify executed software into different threat levels by analyzing Sysmon log streams. The presented system and approach augments cyber defensive capabilities through situational awareness, prediction, and automated courses of action.
Weakly coupled, antiparallel, totally asymmetric simple exclusion processes

Publisher: name: arXiv
Year: 2007
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study a system composed of two parallel totally asymmetric simple exclusion processes with open boundaries, where the particles move in the two lanes in opposite directions and are allowed to jump to the other lane with rates inversely proportional to the length of the system. Stationary density profiles are determined and the phase diagram of the model is constructed in the hydrodynamic limit, by solving the differential equations describing the steady state of the system, analytically for vanishing total current and numerically for nonzero total current. The system possesses phases with a localized shock in the density profile in one of the lanes, similarly to exclusion processes endowed with nonconserving kinetics in the bulk. Besides, the system undergoes a discontinuous phase transition, where coherently moving delocalized shocks emerge in both lanes and the fluctuation of the global density is described by an unbiased random walk. This phenomenon is analogous to the phase coexistence observed at the coexistence line of the totally asymmetric simple exclusion process, however, as a consequence of the interaction between lanes, the density profiles are deformed and in the case of asymmetric lane change, the motion of the shocks is confined to a limited domain.

description: In this paper, we describe a numerical algorithm for the self-consistent simulations of surface water and sediment dynamics. The method is based on the original Lagrangian-Eulerian CSPH-TVD approach for solving the Saint-Venant and Exner equations, taking into account the physical factors essential for the understanding of the shallow water and surface soil layer motions, including complex terrain structure and its evolution due to sediment transport. Additional Exner equation for sediment transport has been used for the numerical CSPH-TVD scheme stability criteria definition. By using OpenMP-CUDA and GPUDirect technologies for hybrid computing systems (supercomputers) with several graphic coprocessors (GPUs) interacting with each other via the PCI-E / NVLINK interface we also develop a parallel numerical algorithm for the CSPH-TVD method. The developed parallel version of the algorithm demonstrates high efficiency for various configurations of Nvidia Tesla CPU + GPU computing systems. In particular, maximal speed up is 1800 for a system with four C2070 GPUs compare to the serial version for the CPU. The calculation time on the GPU V100~(Volta architecture) is reduced by 95 times compared to the GPU C2070~(Fermi architecture).

description: Several observational constraints are imposed on the interacting holographic model of Dark Energy and Dark Matter. First we use the age parameter today, as given by the WMAP results. Subsequently, we explained the reason why it is possible, as recently observed, for an old quasar to be observed in early stages of the universe. We discuss this question in terms of the evolution of the age parameter as well as in terms of the structure formation. Finally, we give a detailed discussion of the constraints implied by the observed CMB low $\ell$ suppression. As a result, the interacting holographic model has been proved to be robust and with reasonable bounds predicts a non vanishing interaction of Dark Energy and Dark Matter.

description: Neutral static alignment, normal movement and a satisfactory segmental interrelationship are described as significant factors in normal asymptomatic function and, when altered, increase the risk of lesions in the lower limbs. It is important to focus on the early identification of joint misalignments. Thus, the present study aims at developing, validating the content developed and confirming the reproducibility of the Dynamic Evaluation Method of Lower Limb Joint Alignment with Parallel Feet (MADAAMI-P), a simple video-based evaluation method using surface markers and a score sheet. The study was carried out in three stages: (1) the Dynamic Evaluation Method of Lower Limb Joint Alignment for dancers (MADAAMI) was adapted; (2) the content validity of the score sheet used in MADAAMI-P was checked; and (3) the intra- and inter-rater reproducibility were evaluated. Cohen's Kappa coefficient and the Intraclass Correlation Coefficient (ICC) were used in the statistical analysis to analyze the categories of the score sheet criteria and sum of the scores (α <0.05). The results showed that MADAAMI-P presents content validity satisfactory.

description: We evaluate a zero-point quantum correction to a Belavin-Polyakov soliton in an isotropic 2D ferromagnet. By revising the scattering problem of quasi-particles by a soliton we show that it leads to the Aharonov-Bohm type of scattering, hence the scattering data can not be obtained by the Born approximation. We proof that the soliton energy with account of quantum corrections does not have a minimum as a function of its radius, which is usually interpreted as a soliton instability. On the other hand, we show that long lifetime solitons can exist in ferromagnets due to an additional integral of motion, which is absent for the sigma-model.

description: We derive integral equation for superconducting gap, which takes into account the quantum nature of electron motion in a parallel magnetic field in a quasi-two-dimensional (Q2D) superconductor in the presence of a non-zero perpendicular field component. By comparison of our theoretical results with the recent experimental data obtained on the NbS$_2$, we show that the orbital effect against superconductivity partially destroys superconductivity in the so-called Ginzburg-Landau area of this Q2D conductor, as expected. Nevertheless, at relatively high magnetic fields, $H \simeq 15 \ T$, the orbital effect starts to improve the Fulde-Ferrell-Larkin-Ovchinnikov phase in the NbS$_2$, due to the quantum nature of electron motion in a parallel magnetic field. In our opinion, this is the most clear demonstration that the orbital effect against superconductivity in a parallel magnetic field has a reversible nature.

description: Recently, a growing attention has been observed toward potential advantages of stem cell (SC)-based therapies in regenerative treatments. Mesenchymal stem/stromal cells (MSCs) are now considered excellent candidates for tissue replacement therapies and tissue engineering. Autologous MSCs importantly contribute to the state-of-the-art clinical strategies for SC-based alveolar bone regeneration. The donor cells and immune cells play a prominent role in determining the clinical success of MSCs therapy. In line with the promising future that stem cell therapy has shown for tissue engineering applications, dental stem cells have also attracted the attention of the relevant researchers in recent years. The current literature review aims to survey the variety and extension of SC-application in tissue-regenerative dentistry. In this regard, the relevant English written literature was searched using keywords: “tissue engineering”, “stem cells”, “dental stem cells”, and “dentistry strategies”. According to the available database, SCs application has become increasingly widespread because of its accessibility, plasticity, and high proliferative ability. Among the growing recognized niches and tissues containing higher SCs, dental tissues are evidenced to be rich sources of MSCs. According to the literature, dental SCs are mostly present in the dental pulp, periodontal ligament, and dental follicle tissues. In this regard, the present review has described the recent findings on the potential of dental stem cells to be used in tissue regeneration.

description: The relation between saddle points of the potential of a classical many-particle system and the analyticity properties of its thermodynamic functions is studied. For finite systems, each saddle point is found to cause a nonanalyticity in the Boltzmann entropy, and the functional form of this nonanalytic term is derived. For large systems, the order of the nonanalytic term increases unboundedly, leading to an increasing differentiability of the entropy. Analyzing the contribution of the saddle points to the density of states in the thermodynamic limit, our results provide an explanation of how, and under which circumstances, saddle points of the potential energy landscape may (or may not) be at the origin of a phase transition in the thermodynamic limit. As an application, the puzzling observations by Risau-Gusman et al. on topological signatures of the spherical model are elucidated.

description: We introduce a new model for dark energy in the universe in which a small cosmological constant is generated by ordinary electromagnetic vacuum energy. The corresponding virtual photons exist at all frequencies but switch from a gravitationally active phase at low frequencies to a gravitationally inactive phase at higher frequencies via a Ginzburg-Landau type of phase transition. Only virtual photons in the gravitationally active state contribute to the cosmological constant. A small vacuum energy density, consistent with astronomical observations, is naturally generated in this model. We propose possible laboratory tests for such a scenario based on phase synchronisation in superconductors.

description: Electrons interact strongly with their environment. The result of these interactions is, most of the time, encoded in an effective mass. In non-relativistic systems, as in condensed matter, the electrons plus interactions form a quasiparticle with an effective mass. From the side of relativistic systems, the fermions also acquire an effective mass due to the interactions with the surrounding medium. We employ a non-perturbative method to calculate the effective mass of relativistic and non-relativistic fermions, in various situations. We find the effective masses up to second order of the iteration method. The results can be of interest in current studies on fermion systems.

description: We describe a reproducible method of fabricating adiabatic tapers with 3-4 micron diameter. The method is based on a heat-and-pull rig, whereby a CO2 laser is continuously scanned across a length of fiber that is being pulled synchronously. Our system relies on a CO2 mirror mounted on a geared stepper motor in order to scan the laser beam across the taper region. We show that this system offers a reliable alternative to more traditional rigs incorporating galvanometer scanners. We have routinely obtained transmission losses between 0.1 and 0.3 dB indicating the satisfactory production of adiabatic tapers. The operation of the rig is described in detail and an analysis on the produced tapers is provided. The flexibility of the rig is demonstrated by fabricating prolate dielectric microresonators using a microtapering technique. Such a rig is of interest to a range of fields that require tapered fiber fabrication such as microcavity-taper coupling, atom guiding along a tapered fiber, optical fiber sensing and the fabrication of fused biconical tapered couplers.

description: Στην παρούσα διατριβή μελετήθηκε η φωτοκαταλυτική αποικοδόμηση τριών οργανοφωσφορικών παρασιτοκτόνων(dichlorvos, dimethoate, methyl parathion) με τη μέθοδο της ετερογενούς και της ομογενούς φωτοκατάλυσης. Σκοπός της παρούσας διατριβής ήταν η μελέτη της φωτοκαταλυτικής οξείδωσης των επιλεγμένων ενώσεων και η εύρεση της κινητικής της αντίδρασης που ακολουθείται, η εξέταση των παραμέτρων που επηρεάζουν την ταχύτητα της φωτοκαταλυτικής οξείδωσης, η εκτίμηση του βαθμού ανοργανοποίησης και της μεταβολής της τοξικότητας παρουσία διαφόρων φωτοκαταλυτικών συστημάτων, η ταυτοποίηση των ενδιάμεσων προϊόντων και τέλος η σύγκριση μεταξύ των μεθόδων που χρησιμοποιήθηκαν. Η φωτοκαταλυτική οξείδωση οδηγεί στην πλήρη εξαφάνιση των ενώσεων και η κινητική που ακολουθείται είναι ψευδό-πρώτης τάξης. Παράμετροι όπως η συγκέντρωση του καταλύτη, το pH, η θερμοκρασία, η προσθήκη του οξειδωτικού, η παρουσία των ανιόντων κ.ά. επηρεάζουν την ταχύτητα της αντίδρασης. Σύγκριση μεταξύ των δύο καταλυτών(TiO2-ZnO) αποδεικνύει ότι το ΤιΟ2 είναι αποτελεσματικότερος καταλύτης. Το Η2Ο2 αποδεικνύεται αποτελεσματικότερο έναντι του K2S2O2 καθότι επιτυγχάνει αύξηση της ταχύτητας οξείδωσης, του βαθμού ανοργανοποίησης καθώς και μείωση της τοξικότητας. Η ομογενής φωτοκατάλυση επιτυγχάνει μικρότερους χρόνους αντίδρασης και παρουσία υπερχλωρικών ιόντων παρατηρείται η μεγαλύτερη μείωση της τοξικότητας απ'ολα τα φωτοκαταλυτικά συστήματα που χρησιμοποιήθηκαν
description: In this study, the photocatalytic degradation of three organasphorous pesticides(dichlorvos, dimethoate, methyl parathion) has been investigated using heterogeneous and homogeneous photocatalysis. The objective were a)to examine the pesticide disappearance, b)to evaluate the kinetics of the photocatalytic oxidation, c)to compare the photocatalytic efficiency of the photocatalysts that were used, d)to examine the effect of various parameters like the mass of catalyst, the addition of an oxidant, temerature, pH etc. e)to evaluate the degree of mineralization f)to examine the toxicity during and at the end of the treatment and finally to identify the organic intermediates that are formed during photocatalytic oxidation. Complete disappearance of the target compounds is achieved using both heterogeneous and homoenous photocatalysis. The photooxidation of the organic compounds follows pseudo-first order kinetic law. Paramenters like the concentration of the catalyst, pH, temperature, addition of an oxidant etc. play an important role affecting the reaction rate. Comparison between the two catalysts(TiO2-ZnO) showed that TiO2 is more efficient photocatalyst. Addition of H2O2 causes an increase of the reaction rate and the degree of mineralization. When combined with TiO2, H2O2 is also able to cause a higher decrease of the toxicity than K2S2O8. Homogenous photocatalysis presence of perchlorate ions higher decrease of the toxicity is also observed

description: We present our proposal for a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor), consisting of a 4-stage X-ray telescope and an array of TES microcalorimeters, cooled with mechanical coolers, with a total weight of about 400 kg. The mission will perform survey observations of warm-hot intergalactic medium using OVII and OVIII emission lines, with the energy coverage up to 1.5 keV. The wide field of view of about 50' diameter, superior energy resolution close to 2 eV FWHM, and very low background will together enable us a wide range of science for diffuse X-ray sources. We briefly describe the design of the satellite, performance of the subsystems and the expected results.

description: Strain engineering is one of the most effective approaches to manipulate the physical state of materials, control their electronic properties, and enable crucial functionalities. Because of their rich phase diagrams arising from competing ground states, quantum materials are an ideal playground for on-demand material control, and can be used to develop emergent technologies, such as adaptive electronics or neuromorphic computing. It was recently suggested that complex oxides could bring unprecedented functionalities to the field of nanomechanics, but the possibility of precisely controlling the stress state of materials is so far lacking. Here we demonstrate the wide and reversible manipulation of the stress state of single-crystal WO3 by strain engineering controlled by catalytic hydrogenation. Progressive incorporation of hydrogen in freestanding ultra-thin structures determines large variations of their mechanical resonance frequencies and induces static deformation. Our results demonstrate hydrogen doping as a new paradigm to reversibly manipulate the mechanical properties of nanodevices based on materials control.

description: Penelitian ini bertujuan untuk menganalisis penetapan imbalan yang wajar bagi inventor paten Alpanhankam yang pelaksanaannya dilakukan oleh pemerintah Indonesia, berdasarkan Undang-Undang Nomor 13 Tahun 2016 tentang Paten dan Peraturan Presiden Nomor 77 Tahun 2020 tentang Tata Cara Pelaksanaan Paten oleh Pemerintah. Fokus utama penelitian ini adalah untuk mengevaluasi apakah ketentuan yang ada sudah cukup memadai dalam memberikan perlindungan hak ekonomi bagi para inventor, terutama terkait dengan mekanisme kompensasi yang adil dan proporsional. Metode penelitian yang digunakan adalah yuridis normatif dengan pendekatan perundang-undangan dan studi kasus implementasi paten oleh pemerintah. Hasil penelitian ini menunjukkan bahwa meskipun terdapat kerangka hukum yang mengatur imbalan, masih terdapat ketidakjelasan dalam penerapannya, khususnya dalam aspek penentuan nilai kompensasi yang dianggap wajar bagi inventor. Temuan ini diharapkan dapat memberikan kontribusi dalam perbaikan kebijakan terkait perlindungan hak ekonomi inventor di Indonesia.

On the size of knots in ring polymers

description: We give two different, statistically consistent definitions of the length l of a prime knot tied into a polymer ring. In the good solvent regime the polymer is modelled by a self avoiding polygon of N steps on cubic lattice and l is the number of steps over which the knot ``spreads'' in a given configuration. An analysis of extensive Monte Carlo data in equilibrium shows that the probability distribution of l as a function of N obeys a scaling of the form p(l,N) ~ l^(-c) f(l/N^D), with c ~ 1.25 and D ~ 1. Both D and c could be independent of knot type. As a consequence, the knot is weakly localized, i.e. ~ N^t, with t=2-c ~ 0.75. For a ring with fixed knot type, weak localization implies the existence of a peculiar characteristic length l^(nu) ~ N^(t nu). In the scaling ~ N^(nu) (nu ~0.58) of the radius of gyration of the whole ring, this length determines a leading power law correction which is much stronger than that found in the case of unrestricted topology. The existence of such correction is confirmed by an analysis of extensive Monte Carlo data for the radius of gyration. The collapsed regime is studied by introducing in the model sufficiently strong attractive interactions for nearest neighbor sites visited by the self-avoiding polygon. In this regime knot length determinations can be based on the entropic competition between two knotted loops separated by a slip link. These measurements enable us to conclude that each knot is delocalized (t ~ 1).
