description: A multitude of searches have already been performed by the ATLAS and CMS collaborations at the LHC to probe the heavy Higgses of the Minimal Supersymmetric Standard Model (MSSM) through their decay to the Standard Model particles. In this paper, we study the decay of the MSSM heavy Higgses into neutralino and chargino pairs and estimate the maximum possible branching ratios for these `ino' modes being consistent with the present LHC data. After performing a random scan of the relevant electroweakino parameters, we impose the SM 125 GeV Higgs constraints, low energy flavour data as well as current bounds on heavy Higgses from the LHC run-I and run-II data. The present limits on the electroweakino masses and couplings are also considered in our analysis. We choose a few representative benchmark points satisfying all the above-mentioned constraints, and then perform a detailed collider simulation, including fast detector effects, and analyze all the potential SM backgrounds in order to estimate the discovery reach of these heavy Higgses at the LHC. We restrict ourselves within the leptonic cascade decay modes of these heavy Higgses and study the mono-X + MET (X=W,Z) and trilepton + MET signatures in the context of high luminosity run of the 14 TeV LHC.

description: We present the evolution in the number density and stellar mass functions of photometrically selected post-starburst galaxies in the UKIDSS Deep Survey (UDS), with redshifts of 0.510. We find that this transitionary species of galaxy is rare at all redshifts, contributing ~5% of the total population at z~2, to <1% by z~0.5. By comparing the mass functions of quiescent galaxies to post-starburst galaxies at three cosmic epochs, we show that rapid quenching of star formation can account for 100% of quiescent galaxy formation, if the post-starburst spectral features are visible for ~250Myr. The flattening of the low mass end of the quiescent galaxy stellar mass function seen at z~1 can be entirely explained by the addition of rapidly quenched galaxies. Only if a significant fraction of post-starburst galaxies have features that are visible for longer than 250Myr, or they acquire new gas and return to the star-forming sequence, can there be significant growth of the red sequence from a slower quenching route. The shape of the mass function of these transitory post-starburst galaxies resembles that of quiescent galaxies at z~2, with a preferred stellar mass of logM~10.6, but evolves steadily to resemble that of star-forming galaxies at z<1. This leads us to propose a dual origin for post-starburst galaxies: (1) at z>2 they are exclusively massive galaxies that have formed the bulk of their stars during a rapid assembly period, followed by complete quenching of further star formation, (2) at z<1 they are caused by the rapid quenching of gas-rich star-forming galaxies, independent of stellar mass, possibly due to environment and/or gas-rich major mergers.

description: In order to search for evidence of hydration on M-type asteroid (16) Psyche, we observed this object in the 3 micron spectral region using the long-wavelength cross-dispersed (LXD: 1.9-4.2 micron) mode of the SpeX spectrograph/imager at the NASA Infrared Telescope Facility (IRTF). Our observations show that Psyche exhibits a 3 micron absorption feature, attributed to water or hydroxyl. The 3 micron absorption feature is consistent with the hydration features found on the surfaces of water-rich asteroids, attributed to OH- and/or H2O-bearing phases (phyllosilicates). The detection of a 3 micron hydration absorption band on Psyche suggests that this asteroid may not be metallic core, or it could be a metallic core that has been impacted by carbonaceous material over the past 4.5 Gyr. Our results also indicate rotational spectral variations, which we suggest reflect heterogeneity in the metal/silicate ratio on the surface of Psyche.

description: The aim of these notes is to provide a reasonably short and "hands-on" introduction to the differential calculus on associative algebras over a field of characteristic zero. Following a suggestion of Ginzburg's we call the resulting theory associative geometry. We argue that this formalism sheds a new light on some classic solution methods in the theory of finite-dimensional integrable dynamical systems.

The Effect of Teachers’ Classroom Test Writing Practices on Students’ Perceived Ratings of Continuous Assessment and College Cumulative Grade Point Averages: The Case of Ethiopian Civil Service and Adama Science and Technology Universities
Creators: name: Sherkabu, Desalegn
Publisher: name: African Journal of Leadership and Development
Year: 2019

description: This paper aims at investigating classroom test Item Writing Practices and challenges of evaluation in the Ethiopian Civil Service University (ECSU) and Adama Science and Technology University (ASTU) with their 370 and 172 sampled university students and instructors respectively. A concurrent quantitative qualitative (QUAN-QUAL) mixed descriptive design was employed. While the universities and faculties and/or departments were chosen by using purposive bases of relative similitude, the sixteen academic leaders and the 13 exam booklets were sampled on accessibility basis. Thus, the study was based on purposive sampling. Data were collected using two sets of questionnaire for the former two sets of respondents, and FGD and interviewees were arranged with the other two groups of respondents. In the questionnaire, the researcher designed a five point Likert scale with 49 items under 11 categories for student respondents, and a five point Likert scale with 61 items under 6 major categories for instructor respondents. Sample examination booklets were closely studied qualitatively. The quantitative data were analyzed using multiple linear regression technique. The study depicted a moderately high rate of standard- about 65.2-80% on the five point scale questionnaire filled in by students. It also revealed (r=0.47), a moderately positive relationship pointing out that a unit of change in college entrance examination (ESLCE) resulted in forty-seven units of change in college CGPA which is direct substantiation of the trend to be in its normal course. Students rated ethical standards as low which verifies the qualitative evidence to the sagging quality of the assessment, contrary to the quantitative data. Accordingly, the assessment and evaluation practices demonstrated both positive achievements and deficiencies. Finally, recommendations were made including a call for a firm follow-up of the process.

Putting the Needle to the Haystack: Submolecular Structure Elucidation with Atomic Force Microscopy in Ultra High Vacuum

Publisher: name: Universität Bielefeld
Year: 2023
Subjects: subject: 530

description: Atomic Force Microscopy and related methods like Kelvin Probe Force Microscopy and Scanning Tunneling Microscopy are valuable assets to investigate structures and sample morphologies beyond the capabilities of optical microscopic methods. Over the course of this work, these shall be employed to perform submolecular structure elucidations in several different systems. In order to be able to distinguish sample molecules from the background they are residing on, the overall works starts with the investigation and preparation of suitable substrates. After parameters for preparation procedures have been established, the molecular scale investigations start with large ligand-metal complexes and therefore validifying their successful synthesis with direct imaging. The next topic are self-assembling monolayers. These classes of molecules can take on a highly ordered quasi-crystallin state when being adsorbed onto a substrate. Different classes of there are studied, as well as the influence of difference substrates like gold and silver on their assembling behavior. When irradiated with electrons, the individual molecules of the self-assembled monolayer form bonds until eventually the whole layer forms an amorphous membrane. These carbon nanomembranes possess remarkable properties like selective permeation. Since the exact origin of this extraordinary high water permeation was so far unknown, this work aims at directly imaging pores that shall give these membranes their properties. In doing so, a scheme was devised to classify pore size distributions, which was subsequently applied to other membrane systems, like cyclodextrin-based filters. The final part revolves around the interaction of DNA with dinuclear metal-complexes. These are designed in such a way to bind to two neighboring phosphate groups of the DNA backbone. This effect aims at blocking polymerase processes in order to stop tumor growth in chemotherapy. While this effect has been shown with several methods, their direct visual confirmation of this binding mode was missing so far. In addition to successfully observing individual molecules bonded onto DNA, an interaction with the vacuum environment was observed, where double strands dissociate into single strands. A causal relation with the complex molecules could be shown with a statistical simulation.

Measurement of the topological surface state optical conductance in bulk-insulating Sn-doped Bi$_{1.1}$Sb$_{0.9}$Te$_2$S single crystals

description: Topological surface states have been extensively observed via optics in thin films of topological insulators. However, in typical thick single crystals of these materials, bulk states are dominant and it is difficult for optics to verify the existence of topological surface states definitively. In this work, we studied the charge dynamics of the newly formulated bulk-insulating Sn-doped Bi$_{1.1}$Sb$_{0.9}$Te$_2$S crystal by using time-domain terahertz spectroscopy. This compound shows much better insulating behavior than any other bulk-insulating topological insulators reported previously. The transmission can be enhanced an amount which is 5$\%$ of the zero-field transmission by applying magnetic field to 7 T, an effect which we believe is due to the suppression of topological surface states. This suppression is essentially independent of the thicknesses of the samples, showing the two-dimensional nature of the transport. The suppression of surface states in field allows us to use the crystal slab itself as a reference sample to extract the surface conductance, mobility, charge density and scattering rate. Our measurements set the stage for the investigation of phenomena out of the semi-classical regime, such as the topological magneto-electric effect.

Strongly confined fluids: Diverging time scales and slowing down of equilibration

description: The Newtonian dynamics of strongly confined fluids exhibits a rich behavior. Its confined and unconfined degrees of freedom decouple for confinement length $L \to 0$. In that case and for a slit geometry the intermediate scattering functions $S_{μν}(q,t)$ simplify, resulting for $(μ,ν) \neq (0,0)$ in a Knudsen-gas like behavior of the confined degrees of freedom, and otherwise in $S_{\parallel}(q,t)$, describing the structural relaxation of the unconfined ones. Taking the coupling into account we prove that the energy fluctuations relax exponentially. For smooth potentials the relaxation times diverge as $L^{-3}$ and $L^{-4}$, respectively, for the confined and unconfined degrees of freedom. The strength of the $L^{-3}$ divergence can be calculated analytically. It depends on the pair potential and the two-dimensional pair distribution function. Experimental setups are suggested to test these predictions.

description: Realistic density dependent CDM3Yn versions of the M3Y interaction have been used in an extended Hartree-Fock (HF) calculation of nuclear matter (NM), with the nucleon single-particle potential determined from the total NM energy based on the Hugenholtz-van Hove theorem that gives rise naturally to a rearrangement term (RT). Using the RT of the single-nucleon potential obtained exactly at different NM densities, the density- and energy dependence of the CDM3Yn interactions was modified to account properly for both the RT and observed energy dependence of the nucleon optical potential. Based on a local density approximation, the double-folding model of the nucleus-nucleus optical potential has been extended to take into account consistently the rearrangement effect and energy dependence of the nuclear mean-field potential, using the modified CDM3Yn interactions. The extended double-folding model was applied to study the elastic $^{12}$C+$^{12}$C and $^{16}$O+$^{12}$C scattering at the refractive energies, where the Airy structure of the nuclear rainbow has been well established. The RT was found to affect significantly the real nucleus-nucleus optical potential at small internuclear distances, giving the potential strength close to that implied by the realistic optical model description of the Airy oscillation.

description: We consider the O(alpha alpha_s) corrections to single on-shell gauge boson production at hadron colliders. We concentrate on the contribution of all the subprocesses where the gauge boson is accompanied by the emission of two additional real partons and we evaluate the corresponding total cross sections. The latter are divergent quantities, because of soft and collinear emissions, and are expressed as Laurent series in the dimensional regularization parameter. The total cross sections are evaluated by means of reverse unitarity, i.e. expressing the phase-space integrals in terms of two-loop forward box integrals with cuts on the final state particles. The results are reduced to a combination of Master Integrals, which eventually are evaluated in terms of Generalized Polylogarithms. The presence of internal massive lines in the Feynman diagrams, due to the exchange of electroweak gauge bosons, causes the appearance of 14 Master Integrals which were not previously known in the literature and have been evaluated via Differential Equations.

description: Using the concept of apparent horizon for dynamical black holes, we revisit the formation of primordial black holes (PBH) in the early universe for both linear and non-linear regimes. First, we develop the perturbation theory for spherically symmetric spacetimes to study the formation of spherical PBHs in linear regime and we fix two gauges. We also introduce a well defined gauge invariant quantity for the expansion. Using this quantity, we argue that PBHs do not form in the linear regime. Finally, we study the non-linear regime. We adopt the spherical collapse picture by taking a closed FRW model in the radiation dominated era to investigate PBH formation. Taking the initial condition of the spherical collapse from the linear theory of perturbations, we allow for both density and velocity perturbations. Our model gives a constraint on the velocity perturbation. This model also predicts that the apparent horizon of PBHs forms when $δ> 3$. Applying the sound horizon constraint, we have shown the threshold value of density perturbations at horizon re-entry must be larger than $δ_{th} > 0.7$ to overcome the pressure gradients.

title: Defining mystical experience : an analysis of issues in the typology of momentary and concrete religious experiences
Creators: name: Mair, Andrew Joseph
Publisher: name: University of Kent
Year: 2023

description: This essay is concerned with the taxonomy of that kind of experience referred to by Trevor. Despite Stace and others, we have as yet no incontrovertible way of deciding whether and on what basis mystical experiences can be constructed as constituting a type and, without knowing this, cannot be certain what our data base encompasses or what kind of approach is indicated. My philosophical analysis of various aspects of the experience presented in mystical reports, I aim to produce a characterisation that the data supports and one which is corrigible. My definition of a mystical type is unconventional largely because I give little role to mystical claims in the characterisation of the experience. The reasons for this are examined in chapters 1 and 2 where I argue that these claims are not meaningful and, in any event, are inaccessible to rational analysis. However, if I note the content of these claims, I do identify certain features about them, notably the concreteness and apparent reality of mystical experience, which could prove to be a basis for typology. Justifying the selection of this feature as distinguishing and defining leads, in chapter 3, to an epistemological debate in which I argue that mentalistic models cannot be explain this feature in the case of mystical perception or indeed perception more generally. Believing concreteness to have a hypothetical importance, I turn away from the sociology of mysticism and, in chapters 4 and 5, find that we can give our subject matter distinctive definition and context by relating it to cyclic and syndromic change in personality which occur in the context of traumatisation. Mystical perception here is defined by its circumstances - a curious sequence in psycho-physiological functioning - and by its sensory or quasi-sensory nature. In chapter 6 I look further into physiology, unsuccessfully, for empirical confirmation of this picture. In conclusion, I explore and answer some of the questions a type, defined in terms of the essentially empirical world of human functioning, poses us. This is not a reductionist account but, this is because my primary aim is giving typology a corrigible basis and only the former aspects of the experience allow this.

description: There are five maximally supersymmetric backgrounds in four-dimensional off-shell N=1 supergravity, two of which are well known: Minkowski superspace M^{4|4} and anti-de Sitter superspace AdS^{4|4}. The three remaining supermanifolds support spacetimes of different topology, which are: R x S^3, AdS_3 x R, and a supersymmetric plane wave isometric to the Nappi-Witten group. As is well known, the Minkowski and anti-de Sitter superspaces are solutions of the Poincaré and anti-de Sitter supergravity theories, respectively. Here we demonstrate that the other three superspaces are solutions of no-scale $R^2$ supergravity. We also present a new (probably the simplest) derivation of the maximally supersymmetric backgrounds of off-shell N=1 supergravity.

description: Due to the growing volume of remote sensing data and the low latency required for safe marine navigation, machine learning (ML) algorithms are being developed to accelerate sea ice chart generation, currently a manual interpretation task. However, the low signal-to-noise ratio of the freely available Sentinel-1 Synthetic Aperture Radar (SAR) imagery, the ambiguity of backscatter signals for ice types, and the scarcity of open-source high-resolution labelled data makes automating sea ice mapping challenging. We use Extreme Earth version 2, a high-resolution benchmark dataset generated for ML training and evaluation, to investigate the effectiveness of ML for automated sea ice mapping. Our customized pipeline combines ResNets and Atrous Spatial Pyramid Pooling for SAR image segmentation. We investigate the performance of our model for: i) binary classification of sea ice and open water in a segmentation framework; and ii) a multiclass segmentation of five sea ice types. For binary ice-water classification, models trained with our largest training set have weighted F1 scores all greater than 0.95 for January and July test scenes. Specifically, the median weighted F1 score was 0.98, indicating high performance for both months. By comparison, a competitive baseline U-Net has a weighted average F1 score of ranging from 0.92 to 0.94 (median 0.93) for July, and 0.97 to 0.98 (median 0.97) for January. Multiclass ice type classification is more challenging, and even though our models achieve 2% improvement in weighted F1 average compared to the baseline U-Net, test weighted F1 is generally between 0.6 and 0.80. Our approach can efficiently segment full SAR scenes in one run, is faster than the baseline U-Net, retains spatial resolution and dimension, and is more robust against noise compared to approaches that rely on patch classification.

description: The Gap Forcing Theorem, a key contribution of this paper, implies essentially that after any reverse Easton iteration of closed forcing, such as the Laver preparation, every supercompactness measure on a supercompact cardinal extends a measure from the ground model. Thus, such forcing can create no new supercompact cardinals, and, if the GCH holds, neither can it increase the degree of supercompactness of any cardinal; in particular, it can create no new measurable cardinals. In a crescendo of what I call exact preservation theorems, I use this new technology to perform a kind of partial Laver preparation, and thereby finely control the class of posets which preserve a supercompact cardinal. Eventually, I prove the `As You Like It' Theorem, which asserts that the class of ${

description: Let $G=PSp(2n, \mathbb C)(n\geq 3)$ and $B$ be a Borel subgroup of $G$ containing a maximal torus $T$ of $G$. Let $w$ be an element of the Weyl group $W$ and $X(w)$ be the Schubert variety in the flag variety $G/B$ corresponding to $w$. Let $Z(w,\underline i)$ be the Bott-Samelson-Demazure-Hansen variety (the desingularization of $X(w)$) corresponding to a reduced expression $\underline i$ of $w$. In this article, we study the cohomology groups of the tangent bundle on $Z(w_0, \underline i)$, where $w_0$ is the longest element of the Weyl group $W$. We describe all the reduced expressions $\underline i$ of $w_0$ in terms of a Coxeter element such that all the higher cohomology groups of the tangent bundle on $Z(w_0, \underline i)$ vanish.

description: Multiple outbursts of a Jupiter-family comet, 15P/Finlay, occurred from late 2014 to early 2015. We conducted an observation of the comet after the first outburst and subsequently witnessed another outburst on 2015 January 15.6-15.7. The gas, consisting mostly of C2 and CN, and dust particles expanded at speeds of 1,110 +/- 180 m/s and 570 +/- 40 m/s at a heliocentric distance of 1.0 AU. We estimated the maximum ratio of solar radiation pressure with respect to the solar gravity beta_max = 1.6 +/- 0.2, which is consistent with porous dust particles composed of silicates and organics. We found that 10^8-10^9 kg of dust particles (assumed to be 0.3 micron - 1 mm) were ejected through each outburst. Although the total mass is three orders of magnitude smaller than that of the 17P/Holmes event observed in 2007, the kinetic energy per unit mass (104 J/kg) is equivalent to the estimated values of 17P/Holmes and 332P/2010 V1 (Ikeya-Murakami), suggesting that the outbursts were caused by a similar physical mechanism. From a survey of cometary outbursts on the basis of voluntary reports, we conjecture that 15P/Finlay-class outbursts occur >1.5 times annually and inject dust particles from Jupiter-family comets and Encke-type comets into interplanetary space at a rate of ~10 kg/s or more.

description: Physical principles constraints the way nonlocal correlations can be distributed among distant parties in a Bell-type experiment. These constraints are usually expressed by monogamy relations that bound the amount of Bell inequality violation observed by a set of parties by the violation observed by a different set of parties. Here we show that the no-signaling principle yields a simple and tight monogamy relations for an important class of bipartite and multipartite Bell inequalities. We also link these trade-offs to the guessing probability--a key quantity in the device-independent information processing.

description: In this paper we propose a framework for automated forecasting of energy-related time series using open access data from European Network of Transmission System Operators for Electricity (ENTSO-E). The framework provides forecasts for various European countries using publicly available historical data only. Our solution was benchmarked using the actual load data and the country provided estimates (where available). We conclude that the proposed system can produce timely forecasts with comparable prediction accuracy in a number of cases. We also investigate the probabilistic case of forecasting - that is, providing a probability distribution rather than a simple point forecast - and incorporate it into a web based API that provides quick and easy access to reliable forecasts.

ASD - Agile Systems Design

description: Die Fähigkeit von Entwicklungsteams, komplexe Probleme mit unklaren und sich schnell ändernden Anforderungen zu lösen, um Produkte mit hohem Innovationspotenzial zu entwickeln, ist ein entscheidender Erfolgsfaktor für Unternehmen. Die Implementierung agiler Ansätze in unternehmerische Denk- und Handlungsweisen unterstützt die iterative, inkrementelle und kundenorientierte Vorgehensweise durch die erhöhte Transparenz und Flexibilität im Handlungssystem. Jedoch müssen diese Ansätze an die individuellen Bedürfnisse, Rahmenbedingungen und Ziele adaptiert werden, um den Entwicklungsteams einen Mehrwert zu bieten. Der Ansatz des ASD – Agile Systems Design adressiert die genannten Anforderungen bei der Planung und Einführung von agilen Entwicklungsprozessen. Für die Anwendung agiler Prozesselemente in den frühen Entwicklungsphasen von Innovationsprojekten und der damit verbundenen Realisierung von Agilität in der Arbeit der Entwicklungsteams bedarf es einer prozessorientierten Unterstützung. Basierend auf dem Verständnis des Modells der PGE – Produktgenerationsentwicklung nach ALBERS wird in dieser Forschungsarbeit ein Framework entwickelt und evaluiert, das den Mensch in den Mittelpunkt der Produktentwicklung stellt und dazu befähigt, ein angemessenes Maß an Agilität zu realisieren, welches der Komplexität der zu bewältigenden Aufgabe entspricht. Dazu wird anhand empirischer Studien aufgezeigt, wie Entwicklungsteams in frühen Entwicklungsphasen durch Coaching Aktivitäten unterstützt werden können, um ihre Problemlösungskompetenzen zu erhöhen, erfolgreich zusammenzuarbeiten sowie Methoden situations- und bedarfsgerecht anzuwenden. Dabei wird das Potenzial durch prozessorientierte Unterstützung der Produktentwickelnde ermittelt und im Rahmen einer präskriptiven Studie zum Aufbau des ASD-Innovation Coaching Frameworks entfaltet. Das ASD-Innovation Coaching unterstützt die Menschen in Entwicklungsteams, damit diese ihre Kompetenzen in einen agilen und zugleich strukturierten Innovationsprozess einbringen können. Die drei zentralen Bestandteile des Frameworks sind die übergreifende Definition von ASDInnovation Coaching mit konkreten Aktivitäten und Verantwortlichkeiten, ein Ausbildungskonzept zur Vermittlung eines entsprechenden Kompetenzprofils sowie ein Vorgehensmodell zur Befähigung der situations- und bedarfsgerechten Anwendung von ASD-Innovation Coaching. Die Evaluationsergebnisse der durchgeführten Fallstudien bestätigen die grundsätzliche Anwendbarkeit und zeigen den Beitrag auf, den das entwickelte Framework in der praktischen Anwendung leistet, um ein angemessenes Maß an Agilität in den Prozessen des ASD – Agile Systems Design zu implementieren sowie die Effektivität und zugleich Kreativität von Entwicklungsteams zu erhöhen.

Snails, time, data: On the politics of mass-digitization and the possibility of data drift

description: In natural history museums around the globe, museum staff are working on making collections of specimens (such as insects on pins, snail shells, dried plants, mounted birds) digitally available through online databases en masse. The mass-digitization of specimens is urgent especially now, so museum actors and biodiversity scientists stress, as natural history collections could provide the biodiversity sciences with crucial data for research into the effects of climate-change induced biodiversity loss. This paper investigates the processes and practices through which these biodiversity data are produced. It argues that the work of data production requires the negotiation of- and grappling with different temporalities, and that attending to these temporalities contributes to a further understanding of the politics of mass-digitization. Building on ethnographic fieldwork in the Museum für Naturkunde Berlin's collection of snail shells, the paper brings into view the work required to make snail specimens and their metadata digital. Following steps in a mollusk digitization workflow—meant to streamline and scale up digitization processes—it attends to the misalignment of rhythms; the importance of informal cleaning labor; the negotiation of social, biological, and colonial temporalities in practices of label transcription; and the anticipatory and expansive logics of mass-digitization. Drawing on snails’ ability to “drift,” it raises data drift as a way of engaging with natural history collections and their data.

description: This paper concerns constructing topological sigma models governing maps from semirigid super Riemann surfaces to general target supermanifolds. We define both the A model and B model in this general setup by defining suitable BRST operators and physical observables. Using supersymmetric localization, we express correlation functions in these theories as integrals over suitable supermanifolds. In the case of the A model, we obtain an integral over the supermoduli space of "superinstantons". The language of supergeometry is used extensively throughout this paper.

Second Minimal Orbits, Sharkovski Ordering and Universality in Chaos

description: This paper introduces the notion of second minimal $n$-periodic orbit of the continuous map on the interval according as if $n$ is a successor of the minimal period of the map in Sharkovski ordering. We pursue classification of second minimal $7$-orbits in terms of cyclic permutations and digraphs. It is proved that there are 9 types of second minimal orbits with accuracy up to inverses. The result is applied to the problem on the distribution of periodic windows within the chaotic regime of the bifurcation diagram of the one-parameter family of unimodal maps. It is revealed that by fixing the maximum number of appearances of the periodic windows there is a universal pattern of distribution. In particular, the first appearance of all the orbits is always a minimal orbit, while the second appearance is a second minimal orbit. It is observed that the second appearance of 7-orbit is a second minimal 7-orbit with Type 1 digraph. The reason for the relevance of the Type 1 second minimal orbit is the fact that the topological structure of the unimodal map with single maximum is equivalent to the structure of the Type 1 piecewise monotonic endomorphism associated with the second minimal 7-orbit. Yet another important report of this paper is the revelation of the universal pattern dynamics with respect to increased number of appearances.
