description: Bioinformatics research in the virology domain requires the support of prior knowledge on viruses. Databases allow for efficient access to structured data due to a large volume capacity, simultaneous access for multiple users, and enabling search and sort functionality on the data. Currently, virus databases are subject to multiple issues or are focused on a particular virus taxonomic group. A universal database that covers all of the publicly available data about viruses is still missing. We tackled this problem by incorporating virus data including from various databases to make a global search platform over their metadata. The resulting outputs allow the user to download selected genome sequences and/or metadata directly. Multiple curation steps will be applied to the metadata derived from each database. The goal of VirJenDB group is to develop an umbrella database covering all viruses in a single platform which will provide user-friendly access to virus sequences and other data for downstream analyses.

description: Let $Δ(x)$ denote the error term in the Dirichlet divisor problem, and $E(T)$ the error term in the asymptotic formula for the mean square of $|ζ(1/2+it)|$. If $E^*(t) = E(t) - 2πΔ^*(t/2π)$ with $Δ^*(x) = -Δ(x) + 2Δ(2x) - {1\over2}Δ(4x)$ and we set $\int_0^T E^*(t) dt = 3πT/4 + R(T)$, then we obtain $$ R(T) = O_ε(T^{593/912+ε}), \int_0^TR^4(t) dt \ll_εT^{3+ε}, $$ and $$ \int_0^TR^2(t) dt = T^2P_3(\log T) + O_ε(T^{11/6+ε}), $$ where $P_3(y)$ is a cubic polynomial in $y$ with positive leading coefficient.

description: We study the general embedding of a $ P(X, φ) $ inflationary theory into a two-field theory with curved field space metric, which was proposed as a possible way to examine the relation between de Sitter Swampland conjecture and \textit{k}-inflation. We show that this embedding method fits into the special type of two-field model in which the heavy field can be integrated out at the full action level. However, this embedding is not exact due to the upper bound of the effective mass of the heavy field. We quantify the deviation between the speed of sound calculated via the $ P(X, φ) $ theory and the embedding two-field picture to next leading order terms. We especially focus on the first potential slow roll parameter defined in the two-field picture and obtain an upper bound on it.

Ερευνώνται γενικότερα οι ιστορικές εξελίξεις στην περιοχή της Ρουμανίας και τους προηγούμενους αιώνες. Ιδιαίτερο βάρος δίνεται στην πνευματική δραστηριότητα και στην Φαναριωτική περίοδο. Ο 19ος αιώνας χωρίζεται στην περίοδο προ και μετά της επανάστασης του 1821 που επηρεάζει και τις Παραδουνάβιες Ηγεμονίες. Οι Ελληνες από το 1835 και έπειτα προοδεύουν στις περιοχές που διαβιούν, σε πνευματικό επίπεδο αλλά και στον εμπορικό τομέα. Ξεχωρίζουν ορισμένες προσωπικότητες με συμμετοχή στον πολιτικό βίο της Ρουμανίας. Τις τελευταίες δεκαετίες οι εξελίξεις σε διακρατικό επίπεδο (Ελλάδα-Ρουμανία) είναι αυτές που ξεχωρίζουν. Θέματα εσωτερικής και εξωτερικής πολιτικής στα τέλη του 19ου αιώνα επηρεάζουν τις ελληνικές κοινότητες της Ρουμανίας.

An Extension of Asgeirsson's Mean Value Theorem for Solutions of the ultra-hyperbolic Equation in Dimension Four

description: In 1937 Asgeirsson established a mean value property for solutions of the general ultra-hyperbolic equation in $2n$ variables. In the case of four variables, it states that the integrals of a solution over certain pairs of conjugate circles are the same. In this paper we extend this result to non-degenerate conjugate conics, which include the original case of conjugate circles and adds the new case of conjugate hyperbolae. The broader context of this result is the geometrization of Fritz John's 1938 analysis of the ultra-hyperbolic equation. Solutions of the equation arise as the compatibility for functions on line space to come from line integrals of functions in Euclidean 3-space. The introduction of the canonical neutral Kaehler metric on the space of oriented lines clarifies the relationship and broadens the paradigm to allow new insights. In particular, it is proven that a solution of the ultra-hyperbolic equation has the mean value property over any pair of curves that arise as the image of John's conjugate circles under a conformal map. These pairs of curves are then shown to be conjugate conics, which include circles and hyperbolae. John identified conjugate circles with the two rulings of a hyperboloid of 1-sheet. Conjugate hyperbolae are identified with the two rulings of either a piece of a hyperboloid of 1-sheet or a hyperbolic paraboloid.
An object-oriented workflow management system

description: Since many organizations have been facing pressure to reduce costs, to increase quality, and to provide rapid delivery of new services and products, they often resort to optimizing the way they do businesses. The use of workflow systems may improve the efficiency of an organizational process, thereby reducing costs and increasing workload capacity. It can also allow people to concentrate on value-added activities by freeing them from worrying about paper flows, filing, information tracing, and whether or not certain actions have been taken. Many workflow products, however, are fundamentally driven by vendor specifications without the support of a well-developed theoretical foundation. This thesis begins with an introduction of an Object- Oriented Workflow Model (OOWM). The OOWM extends an ontologically developed modelling method, Object-Oriented Enterprise Modeling (OOEM), by including workflow constructs with the purpose of describing the task structure of an organizational process. It also presents the architecture of an Object-Oriented Workflow Management System (OOWMS) which enacts the contents of the OOWM. Finally, based on the proposed architectural blueprint, a prototype of the workflow system was implemented, by using existing technologies, for a purchase requisition process.

description: Electroless plating is a powerful tool in nanofabrication and is available for many of the noble transition metals. There is, however, a striking lack of electroless plating procedures for the rarer platinum‐group metals. In this work, two plating baths for nanoscale iridium coatings are developed and their conformality and nanofabrication potential are showcased by coating ion‐track‐etched polycarbonate membranes, creating Ir nanotubes in the process. Both plating solutions yield morphologically different deposits, indicating that the microstructure of the film can be tuned by adjusting the composition of the plating bath. The catalytic performance of the deposited materials is investigated by using membrane‐embedded nanotubes as catalysts for the reduction of 4‐nitrophenol and methyl orange by borohydride, showing remarkable activity and stability. Operation in flow‐through configuration, in which the metallized membrane is implemented as a microreactor greatly enhances the interaction with the catalyst surface, considerably increasing product yield. The results highlight the potential of Ir nanoplating for realizing sophisticated nanostructures and heterogeneous catalysts, but also illustrate the intricacies related to the complex chemistry of electroless Ir plating baths.
Introducing Aspect-Oriented Programming in Improving the Modularity of Middleware for Internet of Things

description: Internet of Things (IoT) has become the buzzword for the development of Smart City and its applications. In this context, development of supporting software forms the core part of the IoT infrastructure. A Middleware sits in between the IoT devices and interacts between them to exchange data among the components of the automated architecture. The Middleware services include hand shaking, data transfer and security among its core set of functionalities. It also includes cross-cutting functional services such as authentication, logging and caching. A software that can run these Middleware services requires a careful choice of a good software modelling technique. Aspect-Oriented Programming (AOP) is a software development methodology that can be used to independently encapsulate the core and cross-cutting functionalities of the Middleware services of the IoT infrastructure. In this paper, an attempt has been made using a simulation environment to independently model the two orthogonal functionalities of the Middleware with the focus to improve its modularity. Further, a quantitative measurement of the core design property of cohesion has been done to infer on the improvement in the reusability of the modules encapsulated in the Middleware of IoT. Based on the measurement, it was found that the modularity and reusability of functionalities in the Middleware software has improved in the AspectJ version compared to its equivalent Java version.

description: Η αιτιότητα είναι μια έννοια κυρίαρχη στη φιλοσοφία του Αριστοτέλη. Η σπουδαιότητα του ρόλου της ίσταται στο ότι αποτελεί το κλειδί για την επιστημονική εξήγηση. Η έννοια αυτή έχει απασχολήσει εντονότατα τους εκπροσώπους της σκέψης, ήδη από την εποχή των Προσωκρατικών φιλοσόφων, και εξακολουθεί να διχάζει την επιστημονική κοινότητα ως τις μέρες μας, οδηγώντας στη δημιουργία αντίπαλων φιλοσοφικών ρευμάτων (Θετικισμός - Επιστημονικός Ρεαλισμός). Ο Αριστοτέλης προσεγγίζει το ζήτημα της αιτιότητας με τρόπο επιστημονικό και συγκροτεί το δικό του αιτιακό σχήμα. Η πρωτοτυπία του έγκειται στο ότι είναι τετραπλό. Έτσι, η Αριστοτελική θεωρία για την αιτιότητα περιλαμβάνει 4 μορφές αιτίων, οι οποίες αντιστοιχούν σε τέσσερις μορφές αιτιακής εξήγησης. Πρόκειται για το υλικό, το μορφικό, το ποιητικό και το τελικό αίτιο. Η γνώση των τεσσάρων αυτών αιτίων οδηγεί, σύμφωνα με το Σταγειρίτη, στην πιο βέβαια γνώση, την επιστημονική, ο κάτοχος της οποίας μπορεί να θεωρηθεί σοφός. Από τα τέσσερα αίτια ο Αριστοτέλης δίνει ιδιαίτερη βαρύτητα στο τελικό. Στο σημείο αυτό ακολουθεί τη διδασκαλία της Ακαδημίας. Ωστόσο, ο Αριστοτέλης δεν είναι ένας ακραιφνής τελολόγος, αλλά μέσα στο κοσμοείδωλό του αφήνει χώρο και για τη δράση του τυχαίου. Η ευελιξία αυτή της σκέψης του μας απομακρύνει από τη μηχανιστική αντίληψη η οποία κυριάρχησε στη σκέψη μέχρι και την εποχή της Νευτώνειας Φυσικής, και παραπέμπει σε σύγχρονες μορφές σκέψης, όπως η Κβαντική Φυσική.
description: The notion of causality is dominant in Aristotle's philosophical system, as it is a key to scientific explanation. Causality haw been studied by many thinkers in the past, and still continues to puzzle philosophers and scientists even nowadays, leading to the establishment of rival philosophical theories (Positivism - Scientific Realism). Aristotle deals with the problem of causality from a scientific point of view, and forms his own causal schema. The Aristotelian theory on causality consists of four types of causes, which correspond with four types of explanation. It is the material, the efficient, the formal and the final cause. Knowledge of these causes is the most certain one, and can lead to scientific explanation. According to Aristotle, the most important cause is the final one. This reminds us of the Academy. However, Aristotle, unlike Plato, is not a strong teleologist, but in his system leaves room for chance and luck. His thought relates with current theories, such as Quantum Physics.

description: We propose a brane configuration for the (2+1)d, $\mathcal{N}=2$ superconformal theories (CFT$_3$) arising from M2-branes probing toric Calabi-Yau 4-fold cones, using a T-duality transformation of M-theory. We obtain intersections of M5-branes on a three-torus which form a 3d bipartite crystal lattice in a way similar to the 2d dimer models for CFT$_4$. The fundamental fields of the CFT$_3$ are M2-brane discs localized around the intersections, and the super-potential terms are identified with the atoms of the crystal. The model correctly reproduces the complete BPS spectrum of mesons and baryons.

Control of charge state of dopants in insulating crystals: Case study of Ti-doped sapphire

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We study mechanisms of control of charge state and concentration of different point defects in doped insulating crystals. The approach is based on the density functional theory calculations. We apply it to the problem of obtaining of Ti-doped sapphire crystals with high figure-of-merit (FOM). The FOM of a given sample is defined as the ratio of the coefficient of absorption at the pump frequency to the coefficient of absorption at the working frequency of Ti:sapphire laser. It is believed that FOM is proportional to the ratio of the concentration of isolated Ti$^{3+}$ ions to the concentration of Ti$^{3+}$-Ti$^{4+}$ pairs. We find that generally this ratio is in inverse proportion to the concentration of Ti$^{4+}$ isolated substitutional defects with the coefficient of proportionality that depends on the temperature at which the thermodynamically equilibrium concentration of defects is reached. We argue that in certain cases the inverse proportion between concentrations of Ti$^{3+}$-Ti$^{4+}$ and Ti$^{4+}$ may be violated. We show that codopants that form positively (negatively) charged defects may decrease (increase) the concentration of positively charged defects formed by the main dopants. To evaluate the effect of codoping it is important to take into account not only isolated defects but defect complexes formed by codopants, as well. In particular, we show that codoping of Ti:sapphire with nitrogen results in an essential increase of the concentration of Ti$^{4+}$ and in a decrease of the FOM, and, consequently, growth or annealing in the presence of nitrogen or its compounds is unfavorable for producing Ti:sapphire laser crystals. The approach developed can be used for determining appropriate growth and annealing conditions for obtaining doped crystals with the required characteristics.

This review tracks the rapid rise and uptake of digital health technology in the healthcare sector over the last one year starting from the early COVID-19 situation till now. It focuses on individual changes around & within the major stakeholders- Policy makers & the health insurance companies who have rapidly gone to adopt more inclusive policies for digital health tech & the insurance companies willing to pay for remote services to an extent. There are multiple patient-related factors that had prevented the common man from accepting digital tech in the past. And even while many of the factors are still in place, the change in social & physical infrastructure has partly forced & partly conditioned people to rampant use of digital health technology. Hospital & healthcare professionals who have been hit harder than many other professionals adopted digital health technology faster than ever & it helped restore resources for patients who need in-office care & maintain social distancing, preventing more spread of the infection. The review also summarizes as to what is needed to keep the impetus on, sustain this newfound adoption & growth of digital health technology.

description: In the cultural enviroment of the Venetian Crete of the Middle Ages (15th-16th centuries) Andreas Ritzos developped a unique expression of his art. He is one of the most important painter of portable icons among the painters of Crete in mid 15th century. In his art factory also works his first son Nikolaos, who belongs to a next generation of painters and is going to form his art identity under the influences of the art of his father. The so far known work of Andreas Ritzos and his cycle of painters who worked around him concludes a wide range of compositions which mainly consists of icons with Virgin enthroned or in a bust. Moreover on the basis of this conformation creates a certain type of the Virgin of Passion, which going to be the prototype for the next generation of artists. In the art composition of his son Nikolaos Ritzos we can see formed iconographic scences which are going to domain in Cretan Iconography. These two painters with the quality of their art contributed in the form of heart identity of many painters.

description: For erbium-doped amorphous oxides, such as those that are used in compact lightwave devices interfaced with silicon, values of the refractive indices are commonly obtained empirically. This work, combining experimental and theoretical studies, examines silica as the exemplary host and the influence of erbium doping on the refractive index. Analysis of data is presented for the spectral refractive index in the ultraviolet to near infrared wavelength range of heavily erbium-doped silica thin films prepared by spin coating a sol-gel precursor on silicon and subsequent vacuum annealing. Effective medium Lorentz-Lorenz data analysis determines that the dopant component has a refractive index of 1.76(0.24) with wavelength dispersion constrained to within 2 percent. Considering the dopant as a localized ErO6 impurity complex, a corresponding theoretical refractive index of 1.662 is derived by calculating the optical polarizability and volume of the impurity. Data presented for room-temperature (293 K) photoluminescence in the vicinity of 1.54 micron are shown to be consistent with random variability in impurity sites. Inherent advantages of studying colloid-based materials are discussed. To the best of the authors knowledge, such a detailed study of the refractive index associated with erbium impurities in silica is being reported for the first time in the literature.

description: We show that brane inflation is very sensitive to tiny sharp features in extra dimensions, including those in the potential and in the warp factor. This can show up as observational signatures in the power spectrum and/or non-Gaussianities of the cosmic microwave background radiation (CMBR). One general example of such sharp features is a succession of small steps in a warped throat, caused by Seiberg duality cascade using gauge/gravity duality. We study the cosmological observational consequences of these steps in brane inflation. Since the steps come in a series, the prediction of other steps and their properties can be tested by future data and analysis. It is also possible that the steps are too close to be resolved in the power spectrum, in which case they may show up only in the non-Gaussianity of the CMB temperature fluctuations and/or EE polarization. We study two cases. In the slow-roll scenario where steps appear in the inflaton potential, the sensitivity of brane inflation to the height and width of the steps is increased by several orders of magnitude comparing to that in previously studied large field models. In the IR DBI scenario where steps appear in the warp factor, we find that the glitches in the power spectrum caused by these sharp features are generally small or even unobservable, but associated distinctive non-Gaussianity can be large. Together with its large negative running of the power spectrum index, this scenario clearly illustrates how rich and different a brane inflationary scenario can be when compared to generic slow-roll inflation. Such distinctive stringy features may provide a powerful probe of superstring theory.

description: Private sustainability standards enable producers, manufacturers and retailers to set credible signals for their products’ sustainability features and allow consumers to allocate their expenses according to their sustainability preferences. But their effects are not always beneficial. While some schemes assess the full range of sustainability impacts throughout the certified products’ lifecycle, the majority of private sustainability standards focuses on a limited range of aspects – risking to provide an uncomprehensive picture of products’ sustainability impact. This lack of transparency seems to affect – in some cases even turn into the negative – standards’ contribution to their stated sustainability goals. In addition, the lack of technical and financial assistance and the great variation and intersection between schemes reportedly impacts market access to the detriment and limits standards’ contribution to sustainability objectives through indirect channels. Subjecting private sustainability standards to rules based on the principles of the Agreement on Technical Barriers to Trade would strengthen their contribution to sustainable development both through direct and indirect channels. In addition, strengthened provisions on technical assistance and cost-sharing arrangements between supply-chain actors could increase small-holders’ participation and enable more informed consumer choices.
However, multilateral agreement on rules applicable to private standards is not in sight. Given the urgent need to regulate private sustainability standards, Members shall step up their efforts – first on the domestic level. The case study on Switzerland-based private sustainability standards indicates that trade-restrictive domestic (and regional) standard landscapes, as well as Members’ involvement in their development and implementation, pose major obstacles to successful negotiations. Acknowledging that trade-restrictive private standards induced by Members are already subject to WTO rules could be an important step towards an ambitious agreement with broad participation. In itself, it will not solve the regulatory challenges ahead. However, it could shift Members’ focus from attempts to excuse trade-restrictive private standards – whether or not they conflict with their internal laws – towards regulation.

description: Η ύπαρξη θηλυκών θεοτήτων ήταν ιδιαίτερα έκδηλη σε όλες τις πολυθεϊστικές θρησκείες ανά τον κόσμο. Γενικότερα το γυναικείο στοιχείο στο ιερό ενσάρκωνε ανάγκες, επιθυμίες, ανθρώπινες αρετές και αδυναμίες. Πολλές υπήρξαν οι αναζητήσεις για την πρώτη ανθρώπινη γυναικεία οντότητα, αλλά και η προσπάθεια απόδοσης θηλυκού γένους στο Αγιο Πνεύμα. Εντούτοις και παρά την πίστη και τις τιμές που αποδίδονται στο πρόσωπο της Παρθένου Μαρίας, αλλά και την αναγνώριση του σημαντικού έργου των διακονισών, η γυναίκα στα πλαίσια των θρησκειών, εξακολουθεί να θεωρείται υποδεέστερη. Γεγονός που καταγράφεται αναλυτικά στο περιεχόμενο των θεμάτων που πραγματεύεται η φεμινιστική θεολογία.
description: The existence of divinities was a fact for all polytheistic religions of world. Generally the female element in sactum substantiated needs, desires, human's virtues and wiknesses. There was many chases for the very first woman, but also and theories for the female gender of Holy Spirit. Although the faith and the honor to Madonna and the asseveretion of the important deaconesses's lifework, woman still de Flater. This fact register analytically in the content of objects that feminism theology threats.

description: We study asymptotics of an irreducible representation of the symmetric group S_n corresponding to a balanced Young diagram λ(a Young diagram with at most C\sqrt{n} rows and columns for some fixed constant C) in the limit as n tends to infinity. We show that there exists a constant D (which depends only on C) with a property that |χ^λ(π)| = | Tr ρ^λ(π)/Tr ρ^λ(e) | < [ D max(1,|π|^2/n) / \sqrt{n}} ]^{|π|}, where |π| denotes the length of a permutation (the minimal number of factors necessary to write πas a product of transpositions). Our main tool is an analogue of Frobenius character formula which holds true not only for cycles but for arbitrary permutations.

description: In the development of quantum microwave-to-optical (MO) converters, excessive noise induced by the parametric optical drive remains a major challenge at milli-Kelvin temperatures. Here we study the extraneous noise added to an electro-optic transducer in its quantum ground state under an intense pulsed optical excitation. The integrated electro-optical transducer leverages the inherent Pockels effect of aluminum nitride microrings, flip-chip bonded to a superconducting resonator. Applying a pulsed optical drive with peak power exceeding the cooling power of the dilution refrigerator at its base temperature, we observe efficient bi-directional MO conversion, with near-ground state microwave thermal excitation ($\bar{n}_\mathrm{e}=0.09\pm0.06$). Time evolution study reveals that the residual thermal excitation is dominated by the superconductor absorption of stray light scattered off the chip-fiber interface. Our results shed light on suppressing microwave noise in a cavity electro-optic system under intense optical drive, which is an essential step towards quantum state transduction between microwave and optical frequencies.

description: Semiconducting monolayer of 2D material are able to concatenate multiple interesting properties into a single component. Here, by combining opto-mechanical and electronic measurements, we demonstrate the presence of a partial 2H-1T phase transition in a suspended 2D monolayer membrane of MoS2. Electronic transport shows unexpected memristive properties in the MoS2 membrane, in the absence of any external dopants. A strong mechanical softening of the membrane is measured concurrently and may only be related to the phase 2H-1T phase transition which imposes a 3percent directional elongation of the topological 1T phase with respect to the semiconducting 2H. We note that only a few percent 2H- 1T phase switching is sufficient to observe measurable memristive effects. Our experimental results combined with First-principles total energy calculations indicate that sulfur vacancy diffusion plays a key role in the initial nucleation of the phase transition. Our study clearly shows that nanomechanics represents an ultrasensitive technique to probe the crystal phase transition in 2D materials or thin membranes. Finally, a better control of the microscopic mechanisms responsible for the observed memristive effect in MoS2 is important for the implementation of future devices.

description: There is a demonstrated discrepancy between consumers’ environmental consciousness and actual purchasing behaviors in relation to clothing consumption. To better understand this phenomenon and identify the challenges that millennials face in their experience with sustainable fashion brands, a study involving qualitative interviews was conducted to gather in-depth data on the firsthand experiences of the participants, fifteen current or recently graduated University of Chicago students at the time of the interviews. Through data analysis and abductive reasoning, six key themes were identified across the interviews, which altogether provided a more holistic overview of millennials’ clothing consumption. Lastly, the qualitative data informed the researcher in generating insight regarding potential ways in which sustainable fashion could more successfully target millennials, including improved marketing strategies, education, and universal certification labels.

description: Most studies of plant–animal mutualistic networks have come from a temporally static perspective. This approach has revealed general patterns in network structure, but limits our ability to understand the ecological and evolutionary processes that shape these networks and to predict the consequences of natural and human‐driven disturbance on species interactions. We review the growing literature on temporal dynamics of plant–animal mutualistic networks including pollination, seed dispersal and ant defence mutualisms. We then discuss potential mechanisms underlying such variation in interactions, ranging from behavioural and physiological processes at the finest temporal scales to ecological and evolutionary processes at the broadest. We find that at the finest temporal scales (days, weeks, months) mutualistic interactions are highly dynamic, with considerable variation in network structure. At intermediate scales (years, decades), networks still exhibit high levels of temporal variation, but such variation appears to influence network properties only weakly. At the broadest temporal scales (many decades, centuries and beyond), continued shifts in interactions appear to reshape network structure, leading to dramatic community changes, including loss of species and function. Our review highlights the importance of considering the temporal dimension for understanding the ecology and evolution of complex webs of mutualistic interactions.

description: The linear and nonlinear response to a microwave electromagnetic field of two c-axis oriented polycrystalline samples of the newly discovered superconductor CaC6 (Tc = 11.5 K) is studied in the superconducting state down to 2 K. The surface resistance Rs and the third order intermodulation distortion, arising from a two-tone excitation, have been measured as a function of temperature and microwave circulating power. Experiments are carried out using a dielectrically loaded copper cavity operating at 7 GHz in a "hot finger" configuration. The results confirm recent experimental findings that CaC6 behaves as a weakly-coupled, fully gapped, superconductor. The weak power dependence of Rs encourages a further investigation of this novel superconductor as a possible alternative to Nb in specific microwave applications.

description: In this article we describe the characteristics of a large integrated linear optical device containing Mach-Zehnder interferometers and describe its potential use as a physically unclonable function. We propose that any tunable interferometric device of practical scale will be intrinsically unclonable and will possess an inherent randomness that can be useful for many practical applications. The device under test has the additional use-case as a general-purpose photonic manipulation tool, with various applications based on the experimental results of our prototype. Once our tunable interferometric device is set to work as a physically unclonable function, we find that there are approximately 6.85x10E35 challenge-response pairs, where each challenge can be quickly reconfigured by tuning the interferometer array for subsequent challenges.

The Neupert Effect of Flare UltraViolet and Soft X-ray Emissions
Creators: name: Qiu, Jiong
Publisher: name: arXiv
Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We model the Neupert effect that relates flare heating energy with the observed SXR emission. The traditional form of the Neupert effect refers to the correlation between the time-integrated HXR or microwave light curve and the SXR light curve. In this paper, instead, we use as the proxy for heating energy the ultraviolet (UV) emission at the foot-points of flare loops, and modify the model of the Neupert effect by taking into account the discrete nature of flare heating as well as cooling. In the modified empirical model, spatially resolved UV lightcurves from the transition region or upper chromosphere are each convolved with a kernel function characterizing the decay of the flare loop emission. Contributions by all loops are summed to compare with the observed total SXR emission. The model has successfully reproduced the observed SXR emission from its rise to decay. To estimate heating energies in flare loops, we also employ the UV Foot-point Calorimeter (UFC) method that infers heating rates in flare loops from these UV light curves and models evolution of flare loops with a zero-dimensional hydrodynamic code. The experiments show that a multitude of impulsive heating events do not well reproduce the observed flare SXR light curve, but a two-phase heating model leads to better agreement with observations. Comparison of the two models of the Neupert effect further allows us to calibrate the UFC method, and improve the estimate of heating rates in flare loops continuously formed by magnetic reconnection throughout the flare evolution.
