description: In this paper, we revise Maxwell's constitutive relation and formulate a system of first-order partial differential equations with two parameters for compressible viscoelastic fluid flows. The system is shown to possess a nice conservation-dissipation (relaxation) structure and therefore is symmetrizable hyperbolic. Moreover, for smooth flows we rigorously verify that the revised Maxwell's constitutive relations are compatible with Newton's law of viscosity.

IGR J17354-3255 as bench test for investigation of gamma-ray emission from Supergiant Fast X-ray Transients

description: Among the different types of sources shining in the high energy sky, gamma-ray binaries are rapidly becoming the subject of major interest. In fact, in the last few years a number of High Mass X-ray Binaries (HMXBs) have been firmly detected from MeV to TeV energies, providing secure evidences that particles can be efficiently accelerated up to very high energies in such galactic systems. Similarly to this general and emerging class of gamma-ray binaries, in principle Supergiant Fast X-ray Transients (SFXTs) have all the "ingredients" to be transient high energy emitters. In this context, the SFXT IGR J17354-3255 is a good bench test and we present intriguing hints likely suggesting that it is a transient gamma-ray source flaring on short timescales. If fully confirmed by further studies, the implications stemming are huge, both theoretically and observationally, and would add a further extreme characteristic to the already extreme class of SFXTs.

description: Efficient discovery of frequent itemsets in large datasets is a crucial task of data mining. In recent years, several approaches have been proposed for generating high utility patterns, they arise the problems of producing a large number of candidate itemsets for high utility itemsets and probably degrades mining performance in terms of speed and space. Recently proposed compact tree structure, viz., UP Tree, maintains the information of transactions and itemsets, facilitate the mining performance and avoid scanning original database repeatedly. In this paper, UP Tree (Utility Pattern Tree) is adopted, which scans database only twice to obtain candidate items and manage them in an efficient data structured way. Applying UP Tree to the UP Growth takes more execution time for Phase II. Hence this paper presents modified algorithm aiming to reduce the execution time by effectively identifying high utility itemsets.

description: Consider the setting of sparse graphs on N vertices, where the vertices have distinct "names", which are strings of length O(log N) from a fixed finite alphabet. For many natural probability models, the entropy grows as cN log N for some model-dependent rate constant c. The mathematical content of this paper is the (often easy) calculation of c for a variety of models, in particular for various standard random graph models adapted to this setting. Our broader purpose is to publicize this particular setting as a natural setting for future theoretical study of data compression for graphs, and (more speculatively) for discussion of unorganized versus organized complexity.

description: The n-point Green functions of Landau gauge QCD are systematically investigated in a Dyson-Schwinger approach assuming a static linearly rising potential between fundamental color charges. Besides quarks also scalar matter in the fundamental representation is considered. Starting from the hypothesis of an 1/k^4 infrared divergent matter-antimatter vertex restrictions on the general color tensor structure of this divergence are derived. Consequences for the other four-point functions of QCD, resp., scalar QCD, are presented. Hereby Casimir scaling is found. It is shown that possible singular contributions to the three-point functions vanish due to cancellations within the color algebra. On the other hand, higher n-point functions inherit the infrared singularity of the matter-antimatter vertex in certain color channels. The presented results show that linear confinement is consistently possible in a Greens function approach, however, at the expense that the decoupling theorem is circumvented by infrared singularities.

title: Nitenpyram detection by a carbon quantum dots-based sensor and molecular modification using 3D-QSAR modeling
Creators: name: Rostami, Masoumeh
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Due to the high demand for agricultural products, pesticides have been widely used to protect crops from potential diseases. Recently, some pesticides have been categorized as harmful emerging contaminants found in natural water, soil, and agricultural products, leading to toxicity for human beings. Therefore, monitoring and controlling their existence in the environment is essential. Carbon quantum dots-based optical sensors are a promising candidate for selective detection of pesticides at low concentrations because of their high sensitivity, selectivity, and fast procedure. In the first part of this study, a hybrid fluorescent sensor based on nitrogen-doped carbon quantum dots (N-CQDs) and silica gel was developed for quantitative detection of nitenpyram, a toxic neonicotinoid existing in the aquatic environment. The prepared N-CQDs@SiO2 sensor exhibited remarkable sensing selectivity and sensitivity towards nitenpyram among the four tested pesticides. A prominent fluorescence quenching of N-CQDs@SiO2 at 445 nm was observed in the presence of nitenpyram with a linear response range of 0–300.0 mg/L and an estimated detection limit of 2.6 mg/L. The excellent sensing selectivity could be attributed to a good affinity between N-CQDs and nitenpyram through hydrogen bonding and π–π interaction, which provokes an auto-absorption of excitation/emission light (IFE) for fluorescence quenching. The design of nitenpyram derivatives with improved environmental properties and functionality and enhanced sensing capacity is a critical way to control the harmfulness of the pesticide. In the second part of this study, 3D-QSAR modeling was adopted to obtain nitenpyram derivatives with improved environmental properties (i.e., biodegradability and bioaccumulation capacity). The functionality of these derivatives as pesticides was further investigated by evaluating their toxicity to pests. Based on the modeling results, the nitenpyram derivatives with higher biodegradability, lower bioaccumulation capacity, and better functionality were selected. They were then examined for their interaction with N-CQDs through molecular docking. The nitenpyram derivative showing a better interaction toward N-CQDs would result in improved sensing and detection. Integrating 3D-QSAR modeling and molecular docking successfully facilitated the design of environmentally friendly nitenpyram derivatives and CQDs-based detection of these products.

description: For decades, there has been criticism of Gross Domestic Product (GDP) as a measure of social progress. Many measurement systems, including indexes (which summarise progress in one number) or dashboards of indicators, have been proposed by  academics, NGOs, international institutes and governments. To overcomes the great heterogeneity, consolidation of methodologies and terminology is needed. 
This report offers a synthesizing framework to categorise the most important Beyond-GDP metrics using a conceptual framework based on the Brundtland and  Stiglitz-Sen-Fitoussi reports. The framework helps to focus on the commonalties between metrics rather than the differences. The "WISE" framework distinguishes three dimensions: wellbeing of current generations ("Wellbeing"), distribution of wellbeing ("Inclusion") and wellbeing of future generations ("Sustainability"). 
The synthesis shows that it is possible to categorise Beyond-GDP metrics using this framework, despite the measurement systems coming from different scientific schools of thought (including welfare economics, needs theories and system-based assessments). An inventory of the many initiatives of governments around the world is also provided as well as an analysis of the influential Beyond-GDP metrics. 
In addition, this report also contains an in-depth discussion of eleven dashboards that are used in European policymaking to illuminate the ability of metrics to effectively steer policymaking into desirable directions. The deep-dive into these monitoring and evaluation frameworks indicates that sustainability is currently the main political priority, with binding political targets having been enacted in this domain. There is, however, a bias towards the environmental dimension of sustainability, while other factors that might affect future wellbeing such as an aging population, are underrepresented. Inclusion is the secondary focus of current EU policymaking, covering a wide range of issues such as income disparities, gender equality, and energy poverty. Wellbeing – while being generally well represented – was found to lack a holistic policy framework. Lastly, the analysis highlighted that using metrics for formulating binding targets and instituting enforcement mechanisms is key to making them matter for policymaking. 
This report shows that the WISE framework is a useful way of synthesising the multitude of Beyond-GDP metrics, which could be very important in the various UN and EC processes currently underway.

Minimal sets of fibre-preserving maps in graph bundles

description: Topological structure of minimal sets is studied for a dynamical system $(E,F)$ given by a fibre-preserving, in general non-invertible, continuous selfmap $F$ of a graph bundle $E$. These systems include, as a very particular case, quasiperiodically forced circle homeomorphisms. Let $M$ be a minimal set of $F$ with full projection onto the base space $B$ of the bundle. We show that $M$ is nowhere dense or has nonempty interior depending on whether the set of so called endpoints of $M$ is dense in $M$ or is empty. If $M$ is nowhere dense, we prove that either a typical fibre of $M$ is a Cantor set, or there is a positive integer $N$ such that a typical fibre of $M$ has cardinality $N$. If $M$ has nonempty interior we prove that there is a positive integer $m$ such that a typical fibre of $M$, in fact even each fibre of $M$ over a \emph{dense open} set $\mathcal O \subseteq B$, is a disjoint union of $m$ circles. Moreover, we show that each of the fibres of $M$ over $B\setminus \mathcal O$ is a union of circles properly containing a disjoint union of $m$ circles. Surprisingly, some of the circles in such "non-typical" fibres of $M$ may intersect. We also give sufficient conditions for $M$ to be a sub-bundle of $E$.

These correlations provide a sensitive experimental test of quantum phase space probabilities quite distinct from the probability densities of $ q,p $. E.g. for EPR states, and entangled generalized coherent states, phase space probabilities which reproduce the correct position and momentum probability densities have to be modified to reproduce these correlations as well.

The Relation Between Environment and Psychological Development: Unpacking Vygotsky’s Influential Concept of Perezhivanie

description: In recent decades, Vygotsky’s sociocultural theory (VST) has become particularly influential in the fields of education and educational psychology. Perezhivanie is an important concept in VST that stipulates a relative influence of environment on a person’s psychological development depending on their age or stage of development. However, perezhivanie has been differentially interpreted and applied in previous literature to suit the purposes of domain-specific research. The lack of a comprehensive theoretical understanding of the concept can undermine research findings and their implications for educational practices. Drawing on a content analysis of Vygotsky’s key texts on perezhivanie, this paper provides a much-needed theoretical discussion that unpacks comprehensively the theoretical content of perezhivanie and the methodological principles guiding its application. The findings revealed that conceptually, perezhivanie can be defined as: (a) a theoretical relation between an individual and their environment, (b) an abstract experience of or attitude towards a life situation and (c) a concrete lived experience of an event within that situation. Four major discernible components of an individual’s perezhivanie include the environmental factor, personal characteristics mobilised, refraction prism and psychological influences. Five key methodological principles were conceived to assist the employment of perezhivanie in educational/psychological research: (1) utilising a perezhivanie as a unit of analysis, (2) analysing perezhivanie at different levels, (3) accounting for the perspective of the individual involved, (4) constructing the refraction prism and (5) determining the major personal characteristics mobilised in the perezhivanie. Implications for educational and research practices are then discussed.

description: Image fusion is the process of integrating multiple images of the same scene into a single fused image to reduce uncertainty and minimizing redundancy while extracting all the useful information from the source images. Image fusion process is required for different applications like medical imaging, remote sensing, medical imaging, machine vision, biometrics and military applications where quality and critical information is required. In this paper, image fusion using fuzzy and neuro fuzzy logic approaches utilized to fuse images from different sensors, in order to enhance visualization. The proposed work further explores comparison between fuzzy based image fusion and neuro fuzzy fusion technique along with quality evaluation indices for image fusion like image quality index, mutual information measure, fusion factor, fusion symmetry, fusion index, root mean square error, peak signal to noise ratio, entropy, correlation coefficient and spatial frequency. Experimental results obtained from fusion process prove that the use of the neuro fuzzy based image fusion approach shows better performance in first two test cases while in the third test case fuzzy based image fusion technique gives better results.

description: Magnetic reconnection in strongly magnetized (low-beta), weakly collisional plasmas is investigated using a novel fluid-kinetic model [Zocco & Schekochihin, Phys. Plasmas 18, 102309 (2011)] which retains non-isothermal electron kinetics. It is shown that electron heating via Landau damping (linear phase mixing) is the dominant dissipation mechanism. In time, electron heating occurs after the peak of the reconnection rate; in space, it is concentrated along the separatrices of the magnetic island. For sufficiently large systems, the peak reconnection rate is $cE_{max}\approx 0.2v_AB_{y,0}$, where $v_A$ is the Alfvén speed based on the reconnecting field $B_{y,0}$. The island saturation width is the same as in MHD models except for small systems, when it becomes comparable to the kinetic scales.

Discerning electronic fingerprints of nodal and antinodal nestings and their phase coherences in doped cuprate superconductors

description: The complexity of competing orders in cuprates has recently been multiplied by a number of bulk evidences of charge ordering with wavevector that connects the antinodal region of the Fermi surface. This results contradicts many spectroscopic results of the nodal nesting. To resolve this issue, we carry out a unified study of the resulting electronic fingerprints of both nodal and antinodal nestings (NNs/ANs), and compare with angle-resolved photoemission, scanning tunneling spectroscopic data, as well as bulk sensitive Hall effect measurements. Our result makes several definitive distinctions between them in that while both nestings gap out the antinodal region, AN induces an additional quasiparticle gap {\em below the Fermi level along the nodal direction}, which is so far uncharted in spectroscopic data. Furthermore, we show that the Hall coefficient in the AN state obtains a discontinuous jump at the phase transition from an electron-like nodal pocket (negative value) to a large hole-like Fermi surface (positive value), in contrast to a continuous transition in the available data. Finally, we write down a Ginzburg-Landau functional to study the stability of the two phases, and discuss an interesting possibility of disorder pinned `chiral' charge ordering.

description: Supergiant Fast X-ray transients are a subclass of high mass X-ray binaries displaying a peculiar and still poorly understood extreme variability in the X-ray domain. These sources undergo short sporadic outbursts (LX ~ 10^36 - 10^37 erg/s), lasting few ks at the most, and spend a large fraction of their time in an intermediate luminosity state at about LX ~ 10^33 - 10^34 erg/s. The sporadic and hardly predictable outbursts of supergiant fast X-ray transients were so far best discovered by large field of view (FOV) coded-mask instruments; their lower luminosity states require, instead, higher sensitivity focusing instruments to be studied in sufficient details. In this contribution, we provide a summary of the current knowledge on Supergiant Fast X-ray Transients and explore the contribution that the new space mission concept LOFT, the Large Observatory For X-ray Timing, will be able to provide in the field of research of these objects.

description: We study a triplet spin valve obtained by intercalating a triplet superconductor spacer between two ferromagnetic regions with non-collinear magnetizations. We demonstrate that the magnetoresitance of the triplet spin valve depends on the relative orientations of the d-vector, characterizing the superconducting state, and the magnetization directions of the ferromagnetic layers. For devices characterized by a long superconductor, the Cooper pairs spintronics regime is reached allowing to observe the properties of a polarized current sustained by Cooper pairs only. In this regime a super-magnetoresistance effect emerges, and the chiral symmetry of the order parameter of the superconducting spacer is easily recognized. Our findings open new perspectives in designing devices based on the cooperative nature of ferromagnetic and triplet correlations in a spintronic framework.

description: This paper considers the problem of filter design with secrecy constraints, where two legitimate parties (Alice and Bob) communicate in the presence of an eavesdropper (Eve), over a Gaussian multiple-input-multiple-output (MIMO) wiretap channel. This problem involves designing, subject to a power constraint, the transmit and the receive filters which minimize the mean-squared error (MSE) between the legitimate parties whilst assuring that the eavesdropper MSE remains above a certain threshold. We consider a general MIMO Gaussian wiretap scenario, where the legitimate receiver uses a linear Zero-Forcing (ZF) filter and the eavesdropper receiver uses either a ZF or an optimal linear Wiener filter. We provide a characterization of the optimal filter designs by demonstrating the convexity of the optimization problems. We also provide generalizations of the filter designs from the scenario where the channel state is known to all the parties to the scenario where there is uncertainty in the channel state. A set of numerical results illustrates the performance of the novel filter designs, including the robustness to channel modeling errors. In particular, we assess the efficacy of the designs in guaranteeing not only a certain MSE level at the eavesdropper, but also in limiting the error probability at the eavesdropper. We also assess the impact of the filter designs on the achievable secrecy rates. The penalty induced by the fact that the eavesdropper may use the optimal non-linear receive filter rather than the optimal linear one is also explored in the paper.

Creators: name: Maier, Nina

description: Interozeption ist die Fähigkeit zur Wahrnehmung und Verarbeitung körperinnerer Signale. Interozeption ist von Bedeutung für die Aufrechterhaltung der Homöostase, körperlicher Selbstwahrnehmung und Entwicklung des Selbst, sowie weist Zusammenhänge mit Psychopathologien und sozialer Kognition auf. Trotz dieses Einflusses der Interozeption auf diverse Konstrukte ist bislang wenig bekannt über die genaue Entwicklung in der frühen Kindheit. Bis zu diesem Zeitpunkt gibt es nur zwei publizierte Forschungsarbeiten, die Säuglinge unter einem Jahr auf interozeptive Sensitivität untersuchten. Es besteht eine Forschungslücke bei Säuglingen über einem Jahr bis zum Vorschulalter. Die vorliegende Studie untersuchte aus diesem Grund 18 Monate alte Säuglinge (N = 54) und ihre Mütter mit der Frage, ob diese bereits eine interozeptive Sensitivität in Bezug auf kardiale und, erstmals in dieser Altersgruppe untersucht, respiratorische Signale zeigen. Hierfür wurde ein Präferenz-Blick-Paradigma genutzt. Das Versuchsdesign stellt eine Replikation einer der zwei angesprochenen Studien dar. Ebenso wurde, als erste Studie, auf einen möglichen Zusammenhang zwischen der interozeptiven Genauigkeit der Mütter auf die interozeptive Sensitivität der Babys eingegangen. Es konnte beobachtet werden, dass die Babys auf Gruppenebene keine Unterschiede in der Blickzeit zeigten. Bei der Betrachtung der individuellen Blickzeiten zeigten sich jedoch Präferenzen. Gefunden wurde kein Zusammenhang zwischen der interozeptiven Genauigkeit der Mutter und der interozeptiven Sensitivität der Babys auf respiratorischer Ebene, jedoch zum Teil auf kardialer Ebene. Die Ergebnisse stimmen nicht mit der replizierten Studie überein, sprechen jedoch für ein Vorhandensein interozeptiver Sensitivität bei 18 Monate alten Säuglingen. Die Ergebnisse liefern wichtige und neue Erkenntnisse zur Interozeption bei Säuglingen. Aufgrund der geringen Anzahl an Forschungsarbeiten und der Bedeutung der Interozeption für die Entwicklung des Selbst bedarf es zukünftiger Studien, die dieses Thema näher beleuchten.

description: We analyse some acoustic emission time series obtained from a lathe machining process. Considering the dynamic evolution of the process we apply two classes of well known stationary stochastic time series models. We apply a preliminary root mean square (RMS) transformation followed by an ARMA analysis; results thereof are mainly related to the description of the continuous part (plastic deformation) of the signal. An analysis of acoustic emission, as some previous works show, may also be performed with the scope of understanding the evolution of the ageing process that causes the degradation of the working tools. Once the importance of the discrete part of the acoustic emission signals (i.e. isolated amplitude bursts) in the ageing process is understood, we apply a stochastic analysis based on point processes waiting times between bursts and to identify a parameter with which to characterise the wear level of the working tool. A Weibull distribution seems to adequately describe the waiting times distribution.

description: Electronic and optoelectronic devices based on thin films of carbon nanotubes are currently limited by the presence of metallic nanotubes. Here we present a novel approach based on nanotube alkyl functionalization to physically remove the metallic nanotubes from such network devices. The process relies on preferential thermal desorption of the alkyls from the semiconducting nanotubes and the subsequent dissolution and selective removal of the metallic nanotubes in chloroform. The approach is versatile and is applied to devices post-fabrication.

description: We report twelve new transit observations of the exoplanet WASP-4b from the Transit Monitoring in the South Project (TraMoS) project. These transits are combined with all previously published transit data for this planet to provide an improved radius measurement of Rp = 1.395 +- 0.022 Rjup and improved transit ephemerides. In a new homogeneous analysis in search for Transit Timing Variations (TTVs) we find no evidence of those with RMS amplitudes larger than 20 seconds over a 4-year time span. This lack of TTVs rules out the presence of additional planets in the system with masses larger than about 2.5 M_earth, 2.0 M_earth, and 1.0 M_earth around the 1:2, 5:3 and 2:1 orbital resonances. Our search for the variation of other parameters, such as orbital inclination and transit depth also yields negative results over the total time span of the transit observations. Finally we perform a simple study of stellar spots configurations of the system and conclude that the star rotational period is about 34 days.

description: The dynamical response of the solar corona to surface and sub-surface perturbations depends on the chromospheric stratification, and specifically on how efficiently these layers reflect or transmit incoming Alfvén waves. While it would be desirable to include the chromospheric layers in the numerical simulations used to study such phenomena, that is most often not feasible. We defined and tested a simple approximation allowing the study of coronal phenomena while taking into account a parametrised chromospheric reflectivity. We addressed the problems of the transmission of the surface rotation to the corona and that of the generation of polar plumes by Alfvén waves (Pinto et al., 2010, 2011). We found that a high (yet partial) effective chromospheric reflectivity is required to properly describe the angular momentum balance in the corona and the way the surface differential rotation is transmitted upwards. Alfvén wave-driven polar plumes maintain their properties for a wide range of values for the reflectivity, but they become bursty (and eventually disrupt) when the limit of total reflection is attained.

description: We consider a classical pure SU(2) gauge theory, and make an ansatz, which separates the space-temporal degrees of freedom from the internal ones. This ansatz is gauge-invariant but not Lorentz invariant. In a limit case of the ansatz, obtained through a contraction map, and corresponding to a vacuum solution, the SU(2) gauge field reduces to an operator, which is the product of the generator of a global U(1) group times a Pauli matrix. We give a geometrical interpretation of the ansatz and of the contraction map in the framework of principal fiber bundles. Then, we identify the internal degrees of freedom of the gauge field with the non-commutative coordinates of the fuzzy sphere in the fundamental representation and obtain a one qubit state.

description: Let ${\rm GK}(G)$ be the prime graph associated with a finite group $G$ and $D(G)$ be the degree pattern of $G$. A finite group $G$ is said to be $k$-fold OD-characterizable if there exist exactly $k$ non-isomorphic groups $H$ such that $|H|=|G|$ and $D(H)=D(G)$. A 1-fold OD-characterizable group is simply called OD-characterizable. The purpose of this paper is threefold. First, it provides the reader with a few useful and efficient tools on OD-characterizability of finite groups. Second, it lists a number of such simple groups that have been already investigated. Third, it shows that the simple groups $L_6(3)$ and $U_4(5)$ are OD-characterizable, too.

description: When a forgery or fake is discovered in a collection, the question becomes: what to do with the item? This thesis examines the work of Veracruz-born sculptor, Brígado Lara, who’s alleged 40-year career of crafting pre-Columbian ceramics calls into question not only how to deal with fakes, but the influential role forged objects have in defining the academic field. A forgery’s historical presence in the scholarly literature, as well as in a museum’s collection, does not end with the acknowledgement that it is non-authentic; there must be careful examination of how the object entered a given collection and how it continues to interact with the scholarly literature. Also important, is research into the forger’s background, including artistic training and relevant biographical information. By comparing two separate case studies of institutions whose prestigious collections include Lara’s sculptures: the Dallas Museum of Art and the Metropolitan Museum of Art. I analyze how each museum approached exhibiting Lara’s objects, as well as details regarding their acknowledgment—or non-acknowledgment—of the “authenticity” of Lara’s forgeries. I offer the conclusion that the Brígado Lara sculptures, due to their acquisition and their influence, must be considered successful artworks: not as forgeries—as Lara never deliberately attempted to attribute his own works as authentic—but as “original interpretations,” which have created new narratives for understanding pre-Columbian ceramics from Veracruz.

description: We propose a probabilistic test, called the deg(f) < k test, for deciding whether the algebraic degree of a cryptographic Boolean function f (given as a black box) is below a certain value k. When f is indeed of degree below k, then f always passes the deg(f) < k test, otherwise it fails each run of the test with a probability dt_k(f). The deg(f) < k test has a good accuracy when the probability dt_k(f) of failing the test is not too small.Ana Salagean initiated the study of the probability dt_k(f) of failing the deg(f) < k test for the case when f is of degree k, and she proved in Theorem 3.32 that there is no function with very low probability dt_k(f), which is in the interval (0.288788, 0.5], and therefore a small number of runs of the test is sufficient to give, with very high probability, the correct answer.We study the probability dt_k(f) when all monomials of f have no variables in common, and prove that dtk_{k-1}(f) >= dt_k(f) holds for this case. Also, we prove that monomials of degree less than k do not alter value of dtk(f).We then study the probability dt_{k-1}(f) of failing the deg(f) < k-1 test when f is of degree k, and we prove that dtk_{k-1}(f) >= dtk(f) holds for particular cases, such as for polynomial classes of one monomial and for all polynomials of degree 2, as well as for the general case. We firstly conjectured these results based on the exact dt_3(f) and dt_4(f) values that we computed for all polynomials of degree 4 in 7 variables, by using the 68431 representatives of equivalence classes listed by Langevin in [33].Interestingly, dtk_{k-1}(f) >= dtk(f) means that the deg(f) < k-1 test works even more effectively than the deg(f) < k test and that the bounds (0.288788, 0.5] also hold for dtk_{k-1}(f) when f is of degree k.We also computed the exact dt_k(f) values for all polynomials of degree k = 1, 2, 3, 4 in 8 variables, by using the representatives of equivalence classes listed by Hou in [17] and by Langevin and Leander listed in [35]. We run the deg(f) < k test experimentally on various stream ciphers, including Trivium, Grain-128a, and SNOW-V. The resulting probability values mostly fall within the range of (0.47, 0.52). Additionally, we used these tests to estimate the degree for these ciphers at different numbers of rounds and different settings for key bits and IV bits.
