description: We investigate real solutions of a C-integrable non-evolutionary partial differential equation in the form of a scalar conservation law where the flux density depends both on the density and on its first derivatives with respect to the local variables. By performing a similarity reduction dictated by one of its local symmetry generators, a nonlinear ordinary differential equation arises that is connected to the Painlevé III equation. Exact solutions are secured and described provided a constraint holds among the coefficients of the original equation. In the most general case, we pinpoint the generation of additional singularities by numerical integration. Then, we discuss the evolution of given initial profiles. Finally, we mention aspects concerning rational solutions with a finite number of poles.

description: This paper analyzes astrophysical scenarios that may be detected at the upper end of the energy range of the Gamma Ray Large Area Space Telescope (GLAST), as a result of cosmic-ray (CR) diffusion in the interstellar medium (ISM). Hadronic processes are considered as the source of $γ$-ray photons from localized molecular enhancements nearby accelerators. Two particular cases are presented: a) the possibility of detecting spectral energy distributions (SEDs) with maxima above 1 GeV, which may be constrained by detection or non-detection at very-high energies (VHE) with observations by ground-based Cerenkov telescopes, and b) the possibility of detecting V-shaped, inverted spectra, due to confusion of a nearby (to the line of sight) arrangement of accelerator/target scenarios with different characteristic properties. We show that the finding of these signatures (in particular, a peak at the 1--100 GeV energy region) is indicative for an identification of the underlying mechanism producing the $γ$-rays that is realized by nature: which accelerator (age and relative position to the target cloud) and under which diffusion properties CR propagate.

description: In this paper, conformal invariant gravitation, based on Weyl geometry, is considered. In addition to the gravitational and matter action integrals, the interaction between the Weyl vector (entered in Weyl geometry) and the vector, representing the world line of the independent observer, are introduced. It is shown that the very existence of such an interaction selects the exponentially growing scale factor solutions among the cosmological vacuums.

The biological determinants of the structure of harpacticoid copepod communities on an estuarine intertidal flat (Fraser River Delta, B.C.)
Creators: name: Harrison, Brenda Jane
Publisher: name: University of British Columbia
Year: 2010

description: The abundance and microspatial distribution of harpacticoid copepods were studied from Jan 1977 to Jan 1980 at two intertidal sites on the Fraser River Delta, B.C.: one (Sand) on the crest of a sand wave and the other (Mud) on the edge of its muddy trough. Eight species formed the communities at the two sites. The composition of the communities was studied by biweekly survey in 1978. Longer term changes in the organization of the sand community were followed by annual mid-winter surveys over four years. Factor analysis was used to group species with similar patterns of seasonal occurrence and macrohabitat distributions. Microspatial patterns in the two communities were compared by heterogeneity chi-square analysis from random core samples collected monthly. The distribution of species relative to small-scale hydraulic bedforms (sand ripples) was studied at the sand site. Distinct patterns of community organization were seen at the two sites. The mud community was characterized by high temporal overlap of species; the sand species showed a distinctive pattern of temporal segregation. Although species in both communities were segregated at small spatial scales, microspatial partitioning was stronger and seasonally more variable in the mud. Spatial patterns in the sand were related to the rippled bedforms. Biogenic structuring by macrobenthos and disturbance by predators were implicated as the causes of microspatial patterns observed in the mud community in summer. Although the two communities showed distinct features of organization they were not completely isolated. Two mud species, Scottolana canadensis and Tachidius triangularis, 'migrated' to the sand in summer. The role of biological interactions in structuring the communities was investigated. Predation by small tidepool fish, Clevelandia ios and Leptocottus armatus, was studied by gut analysis. Predation was species- and size-selective, with two epipelic species, S. canadensis and T. triangularis, occurring most frequently in fish gut samples. A morphometric basis for ontogenetic variation in predation by C. ios was proposed. Evidence to support the hypothesis that competitive interactions help to structure harpacticoid copepod communities was found in changing patterns of abundance, changing patterns of microhabitat use and morphometric character displacement over four years. Competitive interactions were highly dynamic and appeared to be part of the cause of both the temporal and microspatial segregation observed in the sand community in 1979. By 1980, the eight species present in the January sand community formed a displacement series in body sizes. Although each harpacticoid community is unique, numerous parallels exist between the structure and function of the Iona North assemblage and those from shallow water habitats, worldwide. It is clear, therefore, that the conclusions from this research have more than local significance.

description: Bangladesh, one of the most emerging economies of the world, has taken a series of development initiatives on stride towards prosperity over the last 47 years of its independence. In response to this, recently she has undertaken a transformative and globally agreed agenda 2030 on the way to build a sustainable country. To translate the development aspirations into reality, Bangladesh Public Administration Training Centre (BPATC) has aligned the course curricula to create patriotic, competent and professional civil servants dedicated to public interest. The study aimed at analyzing whether the newly recruited civil servants are equipped enough to transform government development initiatives into reality. Here effectiveness of foundation training was critically evaluated by comparing the knowledge of before and after training and by examining their abilities to prioritize targets of SDGs. The study was both qualitative and quantitative in nature. Primary data was collected from all participants of the 66th foundation training course using a structured questionnaire on arrival and departure date. The results show that the Foundation Training has a significant impact on understanding and gaining knowledge regarding SDGs and selecting the area that should get preference while implementing SDGs. Standardized understanding about SDGs among civil servants, especially at entry level usually pick up the pace of its implementation and ultimately bridge the knowledge gap. This training will help them in implementing SDGs in the public sectors of Bangladesh.

description: We present a study of the LHC sensitivity to the W boson mass based on simulation studies. We find that both experimental and phenomenological sources of systematic uncertainties can be strongly constrained with Z measurements: the lineshape is robustly predicted, and its analysis provides an accurate measurement of the detector resolution and absolute scale, while the differential cross-section analysis absorbs most of the strong interaction uncertainties. A sensitivity $δMw \sim 7 \MeV$ for each decay channel (W --> e nu, W --> mu nu), and for an integrated luminosity of 10 fb-1, appears as a reasonable goal.

description: In this paper, optimization of splitting tensile strength and workability of palmyra fibre reinforced concrete was conducted using mixture design of experiment. Thus, twenty-one (21) concrete mixes which constitute single (main) effect, binary interaction and axial blends design points of second order simplex design was generated from iteration of palmyra fibre content varied at 0.5-3% by weight of cement in concrete. The concrete mix proportion was designed for minimum characteristic compressive strength of 20 N/mm2 at 28 days curing period. The workability of the concrete mixes was determined by slump test after which test specimens were produced using 100 𝑚𝑚 diameter, 200 𝑚𝑚 high cylindrical moulds for tensile strength and cured for 28 days. Splitting tensile strength test of the fibre reinforced concrete was conducted after the curing period. The 2nd order simplex polynomial model was fit to the experimental data. Analysis of variance (ANOVA) was used to study the influence of model parameters and their interactions using Minitab 17. Furthermore, the parameters were optimized by maximizing splitting tensile strength and slump values using desirability approach. The optimum settings of parameters are the mixture pseudo components for maximizing the tensile strength and slump test values. The slump has desirability of 0.669138 and the split tensile strength has desirability of 0.459730. The overall desirability index for the responses is 0.554638 at tensile strength of 3.2382 N/mm2 and slump of 19.32 mm

description: In research problems that involve the use of numerical methods for solving systems of ordinary differential equations (ODEs), it is often required to select the most efficient method for a particular problem. To solve a Cauchy problem for a system of ODEs, Runge-Kutta methods (explicit or implicit ones, with or without step-size control, etc.) are employed. In that case, it is required to search through many implementations of the numerical method and select coefficients or other parameters of its numerical scheme. This paper proposes a library and scripts for automated generation of routine functions in the Julia programming language for a set of numerical schemes of Runge-Kutta methods. For symbolic manipulations, we use a template substitution tool. The proposed approach to automated generation of program code allows us to use a single template for editing, instead of modifying each individual function to be compared. On the one hand, this provides universality in the implementation of a numerical scheme and, on the other hand, makes it possible to minimize the number of errors in the process of modifying the compared implementations of the numerical method. We consider Runge-Kutta methods without step-size control, embedded methods with step-size control, and Rosenbrock methods with step-size control. The program codes for the numerical schemes, which are generated automatically using the proposed library, are tested by numerical solution of several well-known problems.

description: The Casimir force between dielectric bodies is well-understood, but not the Casimir force inside a dielectric, in particular its renormalization. We develop and analyse a simple model for the Casimir forces inside a medium that is completely free of renormalization and show then how renormalization emerges. We consider a one-dimensional chain of point particles interacting with each other by scattering the zero-point fluctuations of the electromagnetic field confined to one dimension. We develop a fast, efficient algorithm for calculating the forces on each particle and apply it to study the macroscopic limit of infinitely many, infinitely weak scatterers. The force density converges for piece-wise homogeneous media, but diverges in inhomogeneous media, which would cause instant collapse in theory. We argue that short-range counter forces in the medium prevent this collapse in reality. Their effect appears as the renormalization of the Casimir stress in dielectrics. Our simple model also allows us to derive an elementary analogue of the trace anomaly of quantum fields in curved space.

description: A desirable trait of an artificial agent acting in the visual world is to continually learn a sequence of language-informed tasks while striking a balance between sufficiently specializing in each task and building a generalized knowledge for transfer. Selective specialization, i.e., a careful selection of model components to specialize in each task, is a strategy to provide control over this trade-off. However, the design of selection strategies requires insights on the role of each model component in learning rather specialized or generalizable representations, which poses a gap in current research. Thus, our aim with this work is to provide an extensive analysis of selection strategies for visually grounded continual language learning. Due to the lack of suitable benchmarks for this purpose, we introduce two novel diagnostic datasets that provide enough control and flexibility for a thorough model analysis. We assess various heuristics for module specialization strategies as well as quantifiable measures for two different types of model architectures. Finally, we design conceptually simple approaches based on our analysis that outperform common continual learning baselines. Our results demonstrate the need for further efforts towards better aligning continual learning algorithms with the learning behaviors of individual model parts.

description: The southern part of Bangladesh is positioned on the orifice of Bay of Bengal and is abundant with marine fisheries' huge potential. Whereas marine resources are considered one of the essential sources of future economic development for many countries, Bangladesh is still lagging in this regard. The country cannot materialise full potentials of marine fisheries since more than 90% of fishers use artisanal fishing equipment, and the reasons behind being artisanal fishers are multifaceted. However, it is crucial to know the challenges of artisanal fishers in achieving Sustainable Development Goals (SDGs). This study explored the challenges associated with artisanal fisheries and finds out the solution to help achieve SDGs by providing recommendations. This study was conducted in one of the islands in Bangladesh's coastal area named Sonadia Island to unveil the challenges. Mainly primary data was collected through questionnaire and focus group discussion with the local government elected representative, fishermen association leader, representative of civil society and Upazila level government officials. Secondary data was used to analyse the regulatory and institutional framework. The targets of SDGs were aligned with the importance of artisanal fisheries and the rights of the fishermen. Piracy, local credit system, and complex market chain were identified as significant challenges. Pro-activeness of different government departments can improve the scenario drastically.

description: The problem of nucleon-nucleon correlations and meson exchange currents has been vividly debated in connection with the neutrino-nucleus cross sections. In this work we focus on nucleon-nucleon correlations by discussing a formal correspondence between the approaches based on independent particles and the ab initio approaches involving correlated wave functions. We use a general technique based on unitary transformation mapping the Fermion operators relative to bare nucleons into quasi-particle operators relative to dressed nucleons. We derive formulas for spectral functions, response functions, momentum distribution, separation energy, general enough to be applied with any kind of effective nucleon-nucleon interaction. We establish the relation between the non-energy-weighted sum rule and the Fermi sea depopulation. With our tools we evaluate whether approaches based on effective interactions are compatible with the expected amount of correlations coming from ab initio calculations. For this purpose we use as a test the Fermi sea depopulation and the value of the kinetic energy per nucleon.

description: Weil in den Debatten um den Performativitätsbegriff typischerweise auf Austin und die Sprechakttheorie rekurriert wird, gilt das Modell der Performativität auch in der Soziologie häufig als Inbegriff für die Wirkmächtigkeit von Diskursen, Kommunikationen bzw. sprachlichen Benennungs- und Klassifikationspraktiken. Vor diesem Hintergrund nimmt der Beitrag die in den letzten Jahren mehrfach erfolgte Ausrufung des Performative Turns zum Ausgangspunkt, um zu fragen, ob diese starke Anbindung an die sprachtheoretischen und linguistischen Modelle angesichts der neueren Positionen in diesem Feld überhaupt noch aufrechtzuerhalten ist. Die These ist dabei, dass die vermeintlich evidente Filiation zu Austin und der Sprechakttheorie verstellt, dass es gerade diese sprachtheoretischen Annahmen sind, die in den neueren Positionen zur Debatte stehen. Den Auseinandersetzungen um den Begriff der Performativität liegt demzufolge ein Missverständnis zugrunde, das damit zusammenhängt, dass neuere Ansätze im Unterschied zur Sprechakttheorie und einigen konstruktivistischen und poststrukturalistischen Positionen in diesem Feld nicht sprach-, sondern medientheoretisch argumentieren. Anhand der Positionen von Callon, Latour, MacKenzie und Barad soll im Beitrag gezeigt werden, dass sich aus dem Übergang von der Sprach- zur Medientheorie nicht nur ein anderer epistemischer Ausgangspunkt ergibt, sondern dass die gesamte Debatte dadurch auch eine andere Stoßrichtung und ein gänzlich anders gelagertes Referenzproblem erhält. Weil diese unterschiedlichen und zueinander inkongruenten Theorielinien in der gegenwärtigen Debatte noch nicht hinreichend differenziert sind, kann auch die Herausforderung dieser Positionen nur ungenügend in den Blick genommen werden. Der Beitrag zielt darauf, diese Differenz zwischen sprach- und medientheoretischen Zugängen zu erkunden, um die Tragweite und Grenzen des Performative Turns überhaupt genauer bestimmen zu können. Erst auf Basis dieser Überlegungen kann schließlich diskutiert werden, welche Konsequenzen mit dieser Weiterentwicklung des Performativitätsbegriffs für die soziologische Forschung verbunden sind.

In particular, we demonstrate that all of the thermodynamic properties and hydrodynamic transport parameters for a large class of superconformal gauge theories exhibit a certain universality to leading order in the inverse 't Hooft coupling and $1/N_c$. In particular, we show that independent of the compactification geometry, the leading corrections are derived from the same five-dimensional effective supergravity action supplemented by a term quartic in the five-dimensional Weyl tensor.

We notice that any restriction of QMS in the sense of Ref. \cite{AccFid03} is not necessarily to be a QMS. It turns out that localized QMS has the mentioned property which is called \textit{sub-Markov states}, this allows us to characterize translation invariant QMS on regular trees.

description: The discrete-time GARCH methodology which has had such a profound influence on the modelling of heteroscedasticity in time series is intuitively well motivated in capturing many `stylized facts' concerning financial series, and is now almost routinely used in a wide range of situations, often including some where the data are not observed at equally spaced intervals of time. However, such data is more appropriately analyzed with a continuous-time model which preserves the essential features of the successful GARCH paradigm. One possible such extension is the diffusion limit of Nelson, but this is problematic in that the discrete-time GARCH model and its continuous-time diffusion limit are not statistically equivalent. As an alternative, Klüppelberg et al. recently introduced a continuous-time version of the GARCH (the `COGARCH' process) which is constructed directly from a background driving Lévy process. The present paper shows how to fit this model to irregularly spaced time series data using discrete-time GARCH methodology, by approximating the COGARCH with an embedded sequence of discrete-time GARCH series which converges to the continuous-time model in a strong sense (in probability, in the Skorokhod metric), as the discrete approximating grid grows finer. This property is also especially useful in certain other applications, such as options pricing. The way is then open to using, for the COGARCH, similar statistical techniques to those already worked out for GARCH models and to illustrate this, an empirical investigation using stock index data is carried out.

description: We present ab-initio calculations of the quasi-harmonic temperature dependent elastic constants. The isothermal elastic constants are calculated at each temperature as second derivatives of the Helmholtz free energy with respect to strain and corrected for finite pressure effects. This calculation is repeated for a grid of geometries and the results interpolated at the minimum of the Helmholtz free energy. The results are compared with the quasi-static elastic constants. Thermodynamic relationships are used to derive the adiabatic elastic constants that are compared with the experimental measurements. These approaches are implemented for cubic solids in the $\texttt{thermo_pw}$ code and are validated by applications to silicon, aluminum, and silver.

description: In the context of a voice assistant system, steering refers to the phenomenon in which a user issues a follow-up command attempting to direct or clarify a previous turn. We propose STEER, a steering detection model that predicts whether a follow-up turn is a user's attempt to steer the previous command. Constructing a training dataset for steering use cases poses challenges due to the cold-start problem. To overcome this, we developed heuristic rules to sample opt-in usage data, approximating positive and negative samples without any annotation. Our experimental results show promising performance in identifying steering intent, with over 95% accuracy on our sampled data. Moreover, STEER, in conjunction with our sampling strategy, aligns effectively with real-world steering scenarios, as evidenced by its strong zero-shot performance on a human-graded evaluation set. In addition to relying solely on user transcripts as input, we introduce STEER+, an enhanced version of the model. STEER+ utilizes a semantic parse tree to provide more context on out-of-vocabulary words, such as named entities that often occur at the sentence boundary. This further improves model performance, reducing error rate in domains where entities frequently appear, such as messaging. Lastly, we present a data analysis that highlights the improvement in user experience when voice assistants support steering use cases.

But what exactly is the postcolonial critique, and what are its dangers and possibilities? This lecture builds upon these calls to decolonize sociology while also pushing the postcolonial project further. It offers an analysis of the lineage of postcolonial thought and its apparent opposition to sociological thought. It then specifies the postcolonial critique of sociology and asks how sociology can best respond. A range of examples from social theory, the history of empire, and militarized policing help us better appreciate the need for the postcolonial turn.

An important driver to more closely examine data versioning practices came from the work of the RDA Working Group on Data Citation, whose final report recognised the need for systematic data versioning practices. However, while the recommendations put forward by the RDA WG on Data Citation are well suited for relational databases that are accessed using database queries, the recommendations sparked a debate that highlighted the need for more general principles on data versioning and a clarification of the terminology used to describe versioning of data. This led to the formation of the RDA Working Group on Data Versioning. An early requirement for the new WG was to capture use cases where versioning requirements could not be met by the RDA WG on Data Citation recommendations. Numerous organisations and individuals were approached, or offered to contribute use cases. In the course of the active phase of the RDA Data Versioning Interest Group and then RDA Data Versioning Working Group, 38 use cases from about 33 organisations representing different domains and data types were documented. These are presented below along with contextual information including definitions, workflows and ‘best practices’ for versioning. Analysing the collected use cases and other resources on data versioning we were able to extract versioning patterns. These versioning patterns form the basis of the data versioning principles presented in the Final Report of the RDA Data Versioning Working Group. Version information: The version 1.0 is the original submission of the final report for RDA community review. The Version 1.1 has minor changes from the Version 1.0 following the community review.

description: We present a measurement of the branching fractions for the Cabibbo-favored radiative decay, $D^{0} \to {\bar K}^{*0} γ$, and the Cabibbo-suppressed radiative decay, $D^{0} \to ϕγ$. These measurements are based on a data sample corresponding to an integrated luminosity of $387.1 fb^{-1}$, recorded with the BaBar detector at the PEP-II $e^+e^-$ asymmetric-energy collider operating at center-of-mass energies 10.58 and 10.54 GeV. We measure the branching fractions relative to the well-studied decay $D^{0} \to K^{-} π^{+}$ and find ${\cal B}(D^{0} \to {\bar K}^{*0} γ)/{\cal B}(D^{0} \to K^{-} π^{+}) = (8.43 \pm 0.51 \pm 0.70) \times 10^{-3}$ and ${\cal B}(D^{0} \to ϕγ)/{\cal B}(D^{0} \to K^{-} π^{+}) = (7.15 \pm 0.78 \pm 0.69) \times 10^{-4}$, where the first error is statistical and the second is systematic. This is the first measurement of ${\cal B}(D^{0} \to {\bar K}^{*0} γ)$.

description: We consider models for inflation with a stable inflaton. Reheating is achieved through scattering processes such as $ϕϕ\to h h$, where $h$ is the Standard Model Higgs boson. We consider the reheating process in detail and show that for a relatively large coupling (needed for the late annihilations of the inflaton during freeze-out), reheating is almost instantaneous leading to a relatively high reheating temperature. The process $ϕϕ\leftrightarrow h h$ brings the inflaton back into equilibrium, leading to a well studied scalar singlet dark matter candidate and Higgs portal model. We argue that such models can be derived from no-scale supergravity.

An assessment of host preference, reproductive suitability and feeding injury of the brown marmorated stink bug, Halyomorpha halys, on selected vegetables

description: The brown marmorated stink bug, Halyomorpha halys (Heteroptera), is an invasive insect from Asia that has become a major agricultural pest of field and vegetable crops in the Mid-Atlantic States.  A field study was conducted to asses the seasonal abundance, host plant preference, reproductive suitability, and injury potential of H. haly on green bean, sweet corn, eggplant, okra and bell pepper.  H. halys abundance, life stage phenology, and resulting feeding injury were monitored biweekly throughout the growing season.  Overall seasonal abundance consisted of both overwintered adults and their F1 progeny.  Sweet corn, okra and bell pepper had significantly higher abundances of H. halys compared to green bean, eggplant, and tomato.  Eggplant, okra and bell pepper were the most suitable host plants for H. halys reproduction and development. Sweet corn, okra, bell pepper and tomato were very susceptible to feeding injury and experienced the highest injury rate per stink bug day. The implications of these findings with respect to sampling and management of H. halys in vegetable production are discussed.
Does canonical quantization lead to GKSL dynamics?

description: We introduce a generalized classical model of Brownian motion for describing thermal relaxation processes which is thermodynamically consistent. Applying the canonical quantization to this model, a quantum equation for the density operator is obtained. This equation has a thermal equilibrium state as its stationary solution, but the time evolution is not necessarily a Completely Positive and Trace-Preserving (CPTP) map. In the application to the harmonic oscillator potential, however, the requirement of the CPTP map is shown to be satisfied by choosing parameters appropriately and then our equation reproduces a Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) equation satisfying the detailed balance condition. This result suggests a quantum-classical correspondence in thermal relaxation processes and will provide a new insight to the study of decoherence.

title: The traumatised male : Dada, surrealism and masculinity
Creators: name: Matheson, Neil
Publisher: name: University of Kent
Year: 2001

description: This thesis asserts the crucial role of gender, and in particular of masculinity, in the productions of the dada and surrealist movements. World War I is viewed as having exercised a decisive influence upon the formation of those involved in these movements, producing a generation of "traumatised males", and the question of there being a consequent "crisis in masculinity" is analysed in some detail. These factors are explored within the broader socio-cultural context associated with the development of modernity - shifting gender roles, the emergence of the "New Woman", popular culture, anarchism, etc. Gender is understood here as a largely social construct, with particular attention given to the performative model of gender proposed by Judith Butler. Particular importance is accorded to the entire "fantasmatic" surrounding the machine within the male imaginary, together with the role of related phenomena such as electricity, magnetism and hypnosis. The central actor here is the male body, though masculinity is never considered apart from femininity, and hence the role of femininity, male attitudes towards women and the depiction of the female body, all inevitably figure within the study. Within this general approach, certain specific figures (Andre Breton, Jacques Vache, Max Ernst, Francis Picabia, and Marcel Duchamp) are analysed within specific contexts: including, the impact of the War, Oedipal conflict, the role of the machine, hysteria, fantasy, fetishism and male desire. Running throughout this study is the theme of the physical, corporeal body, the importance of which to the creative process is continually underscored within a range of significant contexts. In an appendix, the continuity of many of these themes is demonstrated in an analysis of the drawings of Antonin Artaud, in which particular attention is given to the interrelationship of machine and body in the specific context of Artaud's electroshock treatment

description: Since 2019, most ad exchanges and sell-side platforms (SSPs), in the online advertising industry, shifted from second to first price auctions. Due to the fundamental difference between these auctions, demand-side platforms (DSPs) have had to update their bidding strategies to avoid bidding unnecessarily high and hence overpaying. Bid shading was proposed to adjust the bid price intended for second-price auctions, in order to balance cost and winning probability in a first-price auction setup. In this study, we introduce a novel deep distribution network for optimal bidding in both open (non-censored) and closed (censored) online first-price auctions. Offline and online A/B testing results show that our algorithm outperforms previous state-of-art algorithms in terms of both surplus and effective cost per action (eCPX) metrics. Furthermore, the algorithm is optimized in run-time and has been deployed into VerizonMedia DSP as production algorithm, serving hundreds of billions of bid requests per day. Online A/B test shows that advertiser's ROI are improved by +2.4%, +2.4%, and +8.6% for impression based (CPM), click based (CPC), and conversion based (CPA) campaigns respectively.

description: The Stokes-Einstein (SE) relation between the self-diffusion and shear viscosity coefficients operates in sufficiently dense liquids not too far from the liquid-solid phase transition. By considering four simple model systems with very different pairwise interaction potentials (Lennard-Jones, Coulomb, Debye-Hückel or screened Coulomb, and the hard sphere limit) we identify where exactly on the respective phase diagrams the SE relation holds. It appears that the reduced excess entropy $s_{\rm ex}$ can be used as a suitable indicator of the validity of the SE relation. In all cases considered the onset of SE relation validity occurs at approximately $s_{\rm ex}\lesssim -2$. In addition, we demonstrate that the line separating gas-like and liquid-like fluid behaviours on the phase diagram is roughly characterized by $s_{\rm ex}\simeq -1$.
