description: Education at all levels is facing several challenges in most countries, such as low quality, high costs, lack of educators, and unsatisfied student demand. Traditional approaches are becoming unable to deliver the required education. Several causes for this inefficiency can be identified. I argue that beyond specific causes, the lack of effective education is related to complexity. However, information technology is helping us overcome this complexity.

description: Motivated by consideration of the solar tachocline, we derive, via an asymptotic procedure, a new set of equations incorporating velocity shear and magnetic buoyancy into the Boussinesq approximation. We demonstrate, by increasing the magnetic field scale height, how these equations are linked to the magneto-Boussinesq equations of Spiegel and Weiss (1982).

Publisher: name: Zenodo
Year: 2023

description: Objective: To observe and analyze the clinical application value of colposcopy in the diagnosis of cervical diseases. 
Methods: The data of 1700 patients who underwent colposcopy in our hospital from June 2018 to February 2022 were retrospectively analyzed, and the examination results were analyzed and summarized. In this study, SPSS13.0 software was used for statistical analysis and summary. 
Results: Among the 1700 patients who received colposcopy, 418 patients had abnormal test results. 418 patients underwent cervical biopsy pathological examination, the results showed that 227 cases had cervical intraepithelial neoplasia, 167 cases had chronic cervicitis, 15 cases had cervical condyloma, and 9 cases had cervical invasive carcinoma. The specificity, sensitivity, negative predictive value, and positive predictive value of colposcopy in the diagnosis of cervical intraepithelial neoplasia were 95.63%, 97.36%, 97.04%, and 96.09%, respectively; the specificity, sensitivity, negative predictive value, and positive predictive value of diagnosing cervical invasive carcinoma were 100%, 77.78%, 99.52%, and 100%, respectively. 
Conclusion: Colposcopy has important clinical value in the diagnosis of cervical diseases, especially in the diagnosis of cervical intraepithelial neoplasia and cervical invasive carcinoma. If combined with histopathological examination, the diagnostic accuracy will be higher. Therefore, colposcopy plays an important role in early diagnosis and treatment of cervical intraepithelial neoplasia and in reducing the incidence of cervical cancer.

What statistics do we need to distinguish between predictions of Bulk Silicate Earth model and Hydridic Earth model for Th/U signal ratio? We obtained the simple formula for estimation of error of Th/U signal ratio. Our calculations show that we need more than $22 kt \cdot year$ exposition for Gran-Sasso underground laboratory and Sudbury Neutrino Observatory. We need more than $27 kt \cdot year$ exposition for Kamioka site in the case of stopping of all Japanese nuclear power plants.

description: Researchers and research organizations have repeatedly pointed to the existence of a data gap concerning populations with marginalized orientations, relationships, genders, asexualities and intersex conditions (MORGAI) (see for example National Academies of Sciences, Engineering, and Medicine, 2020. https://doi.org/10.17226/25877). Yet, while data is needed to conduct research benefitting these populations, from an ethical perspective we need to protect these populations from repeated, duplicate collection of often highly sensitive data. Therefore, in addition to closing the data gap, we argue that efforts must also be made to close the “discovery gap” for this data. We will set out by presenting strategies currently employed by social science data repositories to make MORGAI data in their holdings visible and findable (if any), including curated collections and bibliographies, or the use of controlled vocabularies. We then present first findings from an analysis of web queries and search queries in the catalog of the GESIS data holdings for MORGAI data and put these into context of current research about data discovery strategies of researchers. We conclude by outlining planned measures to facilitate the discovery of MORGAI data in the GESIS collections. Once these have been implemented, we hope to be able to measure potential effects on data discovery by monitoring the download statistics for these data over the course of a 12-month period.

description: Based on a structure consisting of a single graphene layer situated on a periodic dielectric grating, we show theoretically that intense terahertz (THz) radiations can be generated by an electron bunch moving atop the graphene layer. The underlying physics lies in the fact that a moving electron bunch with rather low electron energy ($\sim$1 keV) can efficiently excite graphene plasmons (GPs) of THz frequencies with a strong confinement of near-fields. GPs can be further scattered into free space by the grating for those satisfying the phase matching condition. The radiation patterns can be controlled by varying the velocity of the moving electrons. Importantly, the radiation frequencies can be tuned by varying the Fermi level of the graphene layer, offering tunable THz radiations that can cover a wide frequency range. Our results could pave the way toward developing tunable and miniature THz radiation sources based on graphene.

description: Quasi-two-dimensional fluids can be generated by confining a fluid between two parallel walls with narrow separation. Such fluids exhibit an inhomogeneous structure perpendicular to the walls due to the loss of translational symmetry. Taking the transversal degrees of freedom as a perturbation to an appropriate 2D reference fluid we provide a systematic expansion of the $m$-particle density for arbitrary $m$. To leading order in the slit width this density factorizes into the densities of the transversal and lateral degrees of freedom. Explicit expressions for the next-to-leading order terms are elaborated analytically quantifying the onset of inhomogeneity. The case $m=1$ yields the density profile with a curvature given by an integral over the pair-distribution function of the corresponding 2D reference fluid, which reduces to its 2D contact value in the case of pure excluded-volume interactions. Interestingly, we find that the 2D limit is subtle and requires stringent conditions on the fluid-wall interactions. We quantify the rapidity of convergence for various structural quantities to their 2D counterparts.

description: Context: Currently, most companies apply approaches for product roadmapping that are based on the assumption that the future is highly predicable. However, nowadays companies are facing the challenge of increasing market dynamics, rapidly evolving technologies, and shifting user expectations. Together with the adaption of lean and agile practices it makes it increasingly difficult to plan and predict upfront which products, services or features will satisfy the needs of the customers. Therefore, they are struggling with their ability to provide product roadmaps that fit into dynamic and uncertain market environments and that can be used together with lean and agile software development practices. Objective: To gain a better understanding of modern product roadmapping processes, this paper aims to identify suitable processes for the creation and evolution of product roadmaps in dynamic and uncertain market environments. Method: We performed a Grey Literature Review (GLR) according to the guidelines from Garousi et al. Results: 32 approaches to product roadmapping were identified. Typical characteristics of these processes are the strong connection between the product roadmap and the product vision, an emphasis on stakeholder alignment, the definition of business and customer goals as part of the roadmapping process, a high degree of flexibility with respect to reaching these goals, and the inclusion of validation activities in the roadmapping process. An overall goal of nearly all approaches is to avoid waste by early reducing development and business risks. Besides the list of the 32 approaches, four representative roadmapping processes are described in detail.

description: We analyze the transport of light in the bulk and at the edge of photonic Lieb lattices, whose unique feature is the existence of a flat band representing stationary states in the middle of the band structure that can form localized bulk states. We find that transport in bulk Lieb lattices is significantly affected by the particular excitation site within the unit cell, due to overlap with the flat band states. Additionally, we demonstrate the existence of new edge states in anisotropic Lieb lattices. These states arise due to a virtual defect at the lattice edges and are not described by the standard tight-binding model.

description: Librarians in the Military: information management lessons learned during the Ukraine crisis. Real world crises are challenging for information professionals, especially when established data and information management processes struggle to handle urgent demands for data in a dynamic situation. In 2022, I put my librarian skills to the test when I took a break from my normal duties at the Federal Reserve Bank of Kansas City and deployed to Europe as the Civil Knowledge Integration (CKI) officer for the United States Army in Europe and Africa (USAREUR-AF.) My job as a CKI officer was to manage information requests, find ways to organize information, and facilitate information exchanges between units. On February 24, Russia invaded Ukraine kicking off a major conflict in Europe and the crisis of millions of people fleeing across international borders. This presentation will cover several lessons I learned when faced with the unanticipated challenge of witnessing war on our watch and helping manage the military's information needs. I struggled with two universal problems in data and information management: volume and speed. While there was a wealth of information available, there were inadequate tools for consolidating and evaluating it. Frustration mounted as people attempt to "keep everything" and organization broke down. My first lesson learned was that understanding characteristics of information, like speed of flow and change, are essential in content management strategies. However, the main lesson learned was that information overload is not a technical problem. To quote NYU Professor Clay Shirky: "There's no such thing as information overload. There's only filter failure." In a crisis, technological solutions rarely arrive in time, but applying proper analysis procedures, that focus vague and unanswerable questions into deliverable outcomes, is essential to success. The solution is not just about managing data, but how to ask a better question.

description: The injections of energetic hadrons could have occurred in the early universe by decays of hypothetical long-lived exotic particles. The injections induce the showers of nonthermal hadrons via nuclear scattering. Neutrons generated at these events can react with $^7$Be nuclei and reduce $^7$Be abundance solving a problem of the primordial $^7$Li abundance. We suggest that thermal neutron injection is a way to derive a model independent conservative limit on the relation between abundances of D and $^7$Li in a hadronic energy injection model. We emphasize that an uncertainty in cross sections of inelastic $n+p$ scattering affects the total number of induced neutrons, which determines final abundances of D and $^7$Li. In addition, the annihilations of antinucleons with $^4$He result in higher D abundance and trigger nonthermal $^6$Li production. It is concluded that a reduction of $^7$Li abundance from a value in the standard big bang nucleosynthesis (BBN) model down to an observational two $σ$ upper limit is necessarily accompanied by an undesirable increase of D abundance up to at least an observational 12 $σ$ upper limit from observations of quasi-stellar object absorption line systems. The effects of antinucleons and secondary particles produced in the hadronic showers always lead to a severer constraint. The BBN models involving any injections of extra neutrons are thus unlikely to reproduce a small $^7$Li abundance consistent with observations.

description: A number of resources exist that guide researchers to select an appropriate repository in which to deposit their research data. Most focus repository selection through a specific lens, such as funder requirements, FAIR principles, or sensitive data. This project represents an attempt to develop one interactive tool that lets user needs determine the best path. Three objectives guided us: (1) our Decision Tree needed to account for institutional and national contexts, including funder requirements, legal and ethical frameworks, and institutional practices; (2) we wanted to help researchers make informed decisions about depositing their data and cultivate a deeper understanding of the many factors that might impact their choice; and (3) we wanted to develop a flexible and interactive tool that responds to researchers’ varying priorities and motivations. Our Decision Tree simultaneously helps researchers make the right data repository selection, introduces users to the research data landscape, and streamlines consultation processes and library workflows.

description: In the development of first-principles high-throughput searches for materials with desirable functional properties, there is a clear need for an efficient method to determine the ground state and low-energy alternative structures of superlattices. A method based on a simple strategy -- to generate starting structures based on low-energy structures of the constituent compounds, which are then optimized via structural relaxation calculations -- is proposed. This "stacking method" is demonstrated on the 2:2 PbTiO$_3$/SrTiO$_3$ superlattice, which has been the subject of recent experimental and theoretical interest. Considerations relevant to wider use of the method are discussed.

description: Many bacteriophages modulate host transcription to favor expression of their own genomes. Phage satellite P4 polarity suppression protein, Psu, a building block of the viral capsid, inhibits hexameric transcription termination factor, ρ, by presently unknown mechanisms. Our cryogenic electron microscopy structures of ρ-Psu complexes show that Psu dimers clamp two inactive, open ρ rings and promote their expansion to higher-oligomeric states. ATPase, nucleotide binding and nucleic acid binding studies revealed that Psu hinders ρ ring closure and traps nucleotides in their binding pockets on ρ. Structure-guided mutagenesis in combination with growth, pull-down, and termination assays further delineated the functional ρ-Psu interfaces in vivo. Bioinformatic analyses revealed that Psu is associated with a wide variety of phage defense systems across Enterobacteriaceae, suggesting that Psu may regulate expression of anti-phage genes. Our findings show that modulation of the ρ oligomeric state via diverse strategies is a pervasive gene regulatory principle in bacteria.

description: We utilize Young's algorithm to model the adiabatic compression of the dark matter haloes of galaxies in the THINGS survey to determine the relationship between the halo fit to the rotation curve and the corresponding primordial halo prior to compression. Young's algorithm conserves radial action and angular momentum, resulting in less halo compression than more widely utilized approximations. We find that estimates of the parameters of the NFW haloes fit to the current dark matter distribution systematically overestimate the concentration and underestimate the virial velocity of the corresponding primordial halo. It is the latter that is predicted by dark matter simulations; so accounting for compression is a necessary step for evaluating whether massive galaxies are consistent with dark matter-only simulations. The inferred primordial haloes broadly follow the c-V200 relation expected in a LCDM cosmogony, but often scatter to lower concentrations. We are unable to obtain fits at all for those galaxies whose current dark matter haloes are poorly described by the NFW form. We thus find a mixed bag: some galaxies are reasonably well described by adiabatic compression within a primordial NFW halo, while others require additional mechanisms that reduce the density of dark matter below the primordial initial condition.

description: Within an algebraic framework, used to construct the induced-matter-theory (IMT) setting, in $(D+1)$-dimensional Brans-Dicke (BD) scenario, we obtain a modified BD theory (MBDT) in $D$ dimensions. Being more specific, from the $(D+1)$-dimensional field equations, a $D$--dimensional BD theory, bearing new features, is extracted by means of a suitable dimensional reduction onto a hypersurface orthogonal to the extra dimension. In particular, the BD scalar field in such $D$-dimensional theory has a self-interacting potential, which can be suitably interpreted as produced by the extra dimension. Subsequently, as an application to cosmology, we consider an extended spatially flat FLRW geometry in a $(D+1)$-dimensional space-time. After obtaining the power-law solutions in the bulk, we proceed to construct the corresponding physics, by means of the induced MBDT procedure, on the $D$-dimensional hypersurface. We then contrast the resulted solutions (for different phases of the universe) with those usually extracted from the conventional GR and BD theories in view of current ranges for cosmological parameters. We show that the induced perfect fluid background and the induced scalar potential can be employed, within some limits, for describing different epochs of the universe. Finally, we comment on the observational viability of such a model.

description: Wind and solar PV generation data for the entire contiguous US are calculated, on the basis of 32 years of weather data with temporal resolution of one hour and spatial resolution of 40x40km$^2$, assuming site-suitability-based as well as stochastic wind and solar PV capacity distributions throughout the country. These data are used to investigate a fully renewable electricity system, resting primarily upon wind and solar PV power. We find that the seasonal optimal mix of wind and solar PV comes at around 80% solar PV share, owing to the US summer load peak. By picking this mix, long-term storage requirements can be more than halved compared to a wind only mix. The daily optimal mix lies at about 80% wind share due to the nightly gap in solar PV production. Picking this mix instead of solar only reduces backup energy needs by about 50%. Furthermore, we calculate shifts in FERC (Federal Energy Regulatory Commission)-level LCOE (Levelized Costs Of Electricity) for wind and solar PV due to their differing resource quality and fluctuation patterns. LCOE vary by up to 35% due to regional conditions, and LCOE-optimal mixes turn out to largely follow resource quality. A transmission network enhancement among FERC regions is constructed to transfer high penetrations of solar and wind across FERC boundaries, based on a novel least-cost optimization approach.

description: The magnetic fields associated with young stellar objects are expected to have an hour-glass geometry, i.e., the magnetic field lines are pinched as they thread the equatorial plane surrounding the forming star but merge smoothly onto a background field at large distances. With this field configuration, incoming cosmic rays experience both a funneling effect that acts to enhance the flux impinging on the circumstellar disk and a magnetic mirroring effect that acts to reduce that flux. To leading order, these effects nearly cancel out for simple underlying magnetic field structures. However, the environments surrounding young stellar objects are expected to be highly turbulent. This paper shows how the presence of magnetic field fluctuations affects the process of magnetic mirroring, and thereby changes the flux of cosmic rays striking circumstellar disks. Turbulence has two principle effects: 1) The (single) location of the magnetic mirror point found in the absence of turbulence is replaced with a wide distribution of values. 2) The median of the mirror point distribution moves outward for sufficiently large fluctuation amplitudes (roughly when $δB/B_0>0.2$ at the location of the turbulence-free mirror point); the distribution becomes significantly non-gaussian in this regime as well. These results may have significant consequences for the ionization fraction of the disk, which in turn dictates the efficiency with which disk material can accrete onto the central object. A similar reduction in cosmic ray flux can occur during the earlier protostellar stages; the decrease in ionization can help alleviate the magnetic braking problem that inhibits disk formation.

Impact of Social Responsibility on Corporate Performance: Case Study of South Africa's Retail Chain Company
Creators: name: Matola, Chifundo
Publisher: name: Zenodo
Year: 2023

description: This paper studies the relationship between social responsibility and corporate performance. This study investigates how a South African retail chain company interact with stakeholders, and how this in turn affects the company's revenue and customer loyalty. This study will use a qualitative content method to analyze how the company interacts with its stakeholders and how the interactions between the company and its stakeholders affects the overall company's performance. This study examines the expectations of the stakeholders of Pepkor Holdings limited, determines the extent to which the company meets these expectations, and uses corporate performance indicators to evaluate the relationship between stakeholder treatment and company performance. This study used the secondary data collected from the company report. The results show that customers' decision-making is not only influenced by the characteristics of typical retailer (such as brand), but also by intangible resources (such as corporate social responsibility, corporate image and ethical business practices). In addittion Consumers expect more from companies than affordable prices, good quality and convenience. Engaging in social responsibility activities gives a company competitive advantage. Therefore, in order to win the trust and loyalty of customers, companies should not just abide by the law. The company must determine the specific ways to create value for different stakeholders. Since promoting positive stakeholders' relations has a positive impact on the company's performance, companies need to adjust their own values so that their interaction with stakeholders can ensure mutual benefits. In practice, retail companies must determine how to integrate social responsibility into their corporate strategy in a way that maximizes value created for all stakeholders. The study will complement earlier studies on CSR activities in South Africa, which were not conclusive on the relationship between stakeholder engagement and firm performance. This will also contribute to further studies on this topic, which will continue to explore the positive relationship between corporate social responsibility and corporate performance.

description: We present experimental observations of atom-light interactions within tens of nanometers (down to 11~nm) of a sapphire surface. Using photon counting we detect the fluorescence from of order one thousand Rb or Cs atoms, confined in a vapor with thickness much less than the optical excitation wavelength. The asymmetry in the spectral lineshape provides a direct read-out of the atom-surface potential. A numerical fit indicates a power-law $-C_α/r^α$ with $α=3.02\pm0.06$ confirming that the van der Waals interaction dominates over other effects. The extreme sensitivity of our photon-counting technique may allow the search for atom-surface bound states.
Guidelines for FAIR Vocabularies

description: Shared terminology is key for data sharing, harmonisation of datasets within and across disciplines and cross-domain data integration. Many organizations and disciplines have a tradition of curating lists of terms. These lists come in many forms, from more traditional printed-based word-list or glossaries to machine-readable hierarchical vocabularies or taxonomies, through to axiomatised ontologies. Transitioning and adapting legacy vocabularies, from traditional forms rooted in print technologies, to more broadly accessible modes which are available ubiquitously on-demand is a critical high-value activity. The emergence of semantic technologies facilitates the transition to more accessible vocabularies, and brings the potential for FAIR vocabularies to be used in the context of much larger interconnected communities. This presentation introduces some guidelines for FAIR vocabularies, which are under development by a team working under the auspices of the DDI-CODATA metadata initiative. -- Slides presented as part of the FAIR Convergence Panel - FAIR Convergence Symposium - 30th November 2020 https://conference.codata.org/FAIRconvergence2020/programme/

description: The Arches cluster is a young, densely packed massive star cluster in our Galaxy that shows a high level of star formation activity. The nature of the extended non-thermal X-ray emission around the cluster remains unclear. The observed bright Fe K_alpha line emission at 6.4 keV from material that is neutral or in a low ionization state can be produced either by X-ray photoionization or by cosmic-ray particle bombardment or both. In this paper we report on the first detection of the extended emission around the Arches cluster above 10 keV with the NuSTAR mission, and present results on its morphology and spectrum. The spatial distribution of the hard X-ray emission is found to be consistent with the broad region around the cluster where the 6.4 keV line is observed. The interpretation of the hard X-ray emission within the context of the X-ray reflection model puts a strong constraint on the luminosity of the possible illuminating hard X-ray source. The properties of the observed emission are also in broad agreement with the low-energy cosmic-ray proton excitation scenario.

Small business financing : survey evidence in west Texas
Creators: name: He, Wei
name: Baker, H
Publisher: name: American University
Year: 2023

description: We investigate the financial sources of small firms through a survey of sample firms from West Texas. Evidence shows that the two most common start-up financing alternatives are personal savings and commercial bank loans. Commercial banks remain the most popular source of financing for present and future needs, followed by leasing companies and credit unions. Informal types of financing such as business credit cards, and trade credit are used in addition to lines of credit for transaction and working capital purposes. Firms typically review their financial performance monthly and use common cash balances as the primary financial tool.

description: We derive the quantitative modulus of continuity $$ ω(r)=\left[ p+\ln \left( \frac{r_0}{r} \right) \right]^{-α(n,p)}, $$ which we conjecture to be optimal, for solutions of the $p$-degenerate two-phase Stefan problem. Even in the classical case $p=2$, this represents a twofold improvement with respect to the 1984 state-of-the-art result by DiBenedetto and Friedman [J. reine angew. Math., 1984], in the sense that we discard one logarithm iteration and obtain an explicit value for the exponent $α(n,p)$.

description: In this paper we investigate the role of causal heat transport in a spatially homogeneous, locally-rotationally symmetric Bianchi type-V cosmological model. In particular, the causal temperature profile of the cosmological fluid is obtained within the framework of extended irreversible thermodynamics. We demonstrate that relaxational effects can alter the temperature profile when the cosmological fluid is out of hydrostatic equilibrium.

description: We identify dd-excitations in the quasi-one dimensional compound Ca$_2$Y$_2$Cu$_5$O$_{10}$ using resonant inelastic x-ray scattering. By tuning across the Cu L$_3$-edge, we observe abrupt shifts in the dd-peak positions as a function of incident photon energy. This observation demonstrates orbital-specific coupling of the high-energy excited states of the system to the low-energy degrees of freedom. A Franck-Condon treatment of electron-lattice coupling, consistent with other measurements in this compound, reproduces these shifts, explains the Gaussian lineshapes, and highlights charge-orbital-lattice renormalization in the high energy d-manifold.

Migration of Earth-size planets in 3D radiative discs

description: In this paper, we address the migration of small mass planets in 3D radiative disks. Indeed, migration of small planets is known to be too fast inwards in locally isothermal conditions. However, thermal effects could reverse its direction, potentially saving planets in the inner, optically thick parts of the protoplanetary disc. This effect has been seen for masses larger than 5 Earth masses, but the minimum mass for this to happen has never been probed numerically, although it is of crucial importance for planet formation scenarios. We have extended the hydro-dynamical code FARGO to 3D, with thermal diffusion. With this code, we perform simulations of embedded planets down to 2 Earth masses. For a set of discs parameters for which outward migration has been shown in the range of $[5, 35]$ Earth masses, we find that the transition to inward migration occurs for masses in the range $[3, 5]$ Earth masses. The transition appears to be due to an unexpected phenomenon: the formation of an asymmetric cold and dense finger of gas driven by circulation and libration streamlines. We recover this phenomenon in 2D simulations where we control the cooling effects of the gas through a simple modeling of the energy equation.

Exploring the Textual Alchemy of Legal Gender: Experimental Statutes and the Message in the Medium
Creators: name: Grabham, Emily
Publisher: name: feminists@law
Year: 2020

description: This article draws on original empirical research to explore the politics of experimental feminist statutes. It has two main aims. First, it traces how conventional legislative drafting techniques have participated in the wider social creation and continuance of sex/gender norms. It shows how dominant statutory expressions of sex and gender that might otherwise appear timeless have shifted with social change and legal innovation. The article contributes to debates in feminist legal studies, legal anthropology, and legislative drafting by making visible, and analysing the particular power of legislative text, its ‘alchemy’, in expressing and re-creating sex/gender as a social, cultural and political artefact. Second, drawing on this research, the article explores what the Future of Legal Gender project might consider and do when drafting an experimental statute to decertify legal gender. Addressing questions of positionality, believability, legal form and the use of potentially innovative or contested drafting techniques (the singular “they”, the second person), the article explores tensions between legislative drafting and feminist legal method, as well as the benefits for bringing feminist analysis and perspectives to this important aspect of legal practice. Given that legislative drafting does not merely inscribe pre-agreed policy ideas into legal text but helps to shape emerging ontologies of gender, then drafting an experimental statute invites feminists to pay attention to interlinked questions of substance and form in the exploration of prefigurative legal futures.

description: This paper aims at providing a survey on the problems that can be easily addressed by clonalbased cellular automata in bioinformatics. Researchers try to address the problems in bioinformatics independent of each problem. None of the researchers has tried to relate the major problems in bioinformatics and find a solution using common frame work. We tried to find various problems in bioinformatics which can be addressed easily by clonal based cellular automata. Extensive literature survey is conducted. We have considered some papers in various journals and conferences for conduct of our research. This paper provides intuition towards relating various problems in bioinformatics logically and tries to attain a common frame work with respect to clonal based cellular automata classifier for addressing the same.
