description: Magnetic Resonance Imaging (MRI) is one of the fields that the compressed sensing theory is well utilized to reduce the scan time significantly leading to faster imaging or higher resolution images. It has been shown that a small fraction of the overall measurements are sufficient to reconstruct images with the combination of compressed sensing and parallel imaging. Various reconstruction algorithms has been proposed for compressed sensing, among which Augmented Lagrangian based methods have been shown to often perform better than others for many different applications. In this paper, we propose new Augmented Lagrangian based solutions to the compressed sensing reconstruction problem with analysis and synthesis prior formulations. We also propose a computational method which makes use of properties of the sampling pattern to significantly improve the speed of the reconstruction for the proposed algorithms in Cartesian sampled MRI. The proposed algorithms are shown to outperform earlier methods especially for the case of dynamic MRI for which the transfer function tends to be a very large matrix and significantly ill conditioned. It is also demonstrated that the proposed algorithm can be accelerated much further than other methods in case of a parallel implementation with graphics processing units (GPUs).

description: The objective of this paper is to assess the relationship between fine Particulate Matter (PM) concentrations and health indicators for acute morbidity. The methods used are linear correlation and non-parametric correlation analysis of a time series study conducted in Sofia from 1 January 2017 to 31 May 2019. Data from 4 local health sources that cover hospital admissions and all Emergency Medical Aid registrations from Sofia’s population of 1.3 million. Results were obtained: The mean daily PM10 concentration was 35 μg/m3 with a range from 5 to 336 μg/m3. The mean daily PM2.5 concentration was 11.7 μg/m3 with a range from 2 to 136 μg/m3. In 15.3% of the times, the daily PM2.5 or PM10 concentrations did not meet the WHO Air Quality Guidelines target during the study period. At these excesses, acute infections of the upper respiratory tract and pneumonia increase by 47% and 60%, respectively. COPD increases with 36%, there are also changes and acute bronchitis. Conclusions: The findings provide a justification that exceeds the concentrations of PM10 and PM2.5 were significantly associated with indicators of acute morbidity in Sofia.

Functional Neocortical Movement Encoding in the Rat

Subjects: subject: Neuroscience
subject: Motor cortex
subject: Behaviour

description: The motor cortex has long been known to play a central role in the generation and control of volitional movement, yet its intrinsic functional organization is not fully understood. Two alternate views on the functional organization of motor cortex have been proposed. Short-duration (>50 ms) intracortical stimulation (SD-ICMS) reveals a somatotopic representation of body musculature, whereas long-duration (~500 ms) ICMS (LD-ICMS) reveals a topographic representation of coordinated movement endpoint postures. The functional organization of motor cortex in the rat was probed using combined approaches of in vivo microstimulation, behavioural analysis of forelimb motor performance, and acute cortical cooling deactivation. The first study, using a rodent model of Parkinson’s disease and therapeutic deep brain stimulation of the subthalamic nucleus, determined that acute changes (<60 s) in cortical output function and motor performance are reflected in reversible alterations in movement thresholds and representation sizes. A second study characterized forelimb movement representations under SD-ICMS revealing a dual-representation (digit, wrist, elbow, shoulder) within rostral (RFA) and caudal (CFA) forelimb motor areas. LD-ICMS elicited forelimb reach-to-grasp behaviour (elevate, advance, grasp, retract) with a functional segregation between RFA (grasp) and CFA (elevate, advance, retract) representations. Behaviourally distinct functional roles between these two areas was confirmed through behavioural assessment during selective cortical cooling deactivation. A final study demonstrated increased movement representation overlap assessed with LD-ICMS following repeated kindled-seizures that was not attributed to changes in intracortical inhibition. Current experimentation provides the first causal evidence for movement-based rather than muscle-based functional organization of motor cortex and functional neocortical movement encoding in the rat.
The Beliaev Broken Symmetry Description of Superfluidity vs the Classical-Field Approach

Year: 2012
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: The standard theoretical basis for understanding superfluidity in Bose systems was formulated by Beliaev in 1957, based on splitting the quantum field operator into a macroscopically occupied condensate component and a non-condensate component. This leads to a description of the condensate in terms of a 'single-particle state', the so-called macroscopic wavefunction. Since the discovery of Bose-condensed gases, an alternative theoretical picture has been developed which is based on a 'coherent band' of classically occupied states. This is often called the classical or c-field approach. The goal of this chapter is to review the differences between the Beliaev broken symmetry and c-field approach, and to argue that the c-field concept of a coherent condensate band of states has problems as a description of Bose superfluidity. However, the c-field idea of treating the lowest energy excitations classically can be used to advantage to simplify calculations within the Beliaev broken-symmetry formalism.

description: This paper develops uniqueness theory for 3D phase retrieval with finite, discrete measurement data for strong phase objects and weak phase objects, including: (i) {\em Unique determination of (phase) projections from diffraction patterns} -- General measurement schemes with coded and uncoded apertures are proposed and shown to ensure unique reduction of diffraction patterns to the phase projection for a strong phase object (respectively, the projection for a weak phase object) in each direction separately without the knowledge of relative orientations and locations. (ii) {\em Uniqueness for 3D phase unwrapping} -- General conditions for unique determination of a 3D strong phase object from its phase projection data are established, including, but not limited to, random tilt schemes densely sampled from a spherical triangle of vertexes in three orthogonal directions and other deterministic tilt schemes. (iii) {\em Uniqueness for projection tomography} -- Unique determination of an object of $n^3$ voxels from generic $n$ projections or $n+1$ coded diffraction patterns is proved. This approach of reducing 3D phase retrieval to the problem of (phase) projection tomography has the practical implication of enabling classification and alignment, when relative orientations are unknown, to be carried out in terms of (phase) projections, instead of diffraction patterns. The applications with the measurement schemes such as single-axis tilt, conical tilt, dual-axis tilt, random conical tilt and general random tilt are discussed.

description: The recent loss of interaction in public space has been a topic of debate amongst scholars, architects, urban planners and municipal authorities. This project was undertaken with the initial task of increasing interaction in and within public space. It was imperative to understand the current status of North American public spaces as well as the psychological importance of individual and collective needs for it. A group of radical, avant-garde artists known as the Situationist International theorized various approaches to encouraging awareness of the spaces we dwell in and deemed the term psychogeography: a method of re-contextualizing and learning about the urban realm through the construction of situations. Public experience and expression were at the forefront of their work and led to the final and most pertinent concern regarding public space – boredom. This Master’s thesis therefore turned into a study of expression and ownership of public spaces and is concluded with one design solution titled The C.I.T.E.E. Project.

description: We consider central exclusive production of $gg$ dijets in proton-proton (proton-antiproton) collisions at LHC and Tevatron for different intermediate and final gluon polarisations. The amplitude for the process is derived within the $k_\perp$-factorization approach (with both the standard QCD and the Lipatov's effective three-gluon verticies) and is considered in various kinematical asymptotia, in particular, in the important limit of high-$p_\perp$ jets. Compared to earlier works we include emissions of gluons from different gluonic $t$-channel lines as well as emission of quark-antiquark dijets. Rapidity distributions, gluon jet $p_\perp$ distributions and invariant dijet mass distributions are presented. We explore the competition of the standard diagram with both jets emitted from a single $t$-channel gluon and the one with the emission from both $t$-channel gluons. The second mechanism requires a special treatment. We propose two different approaches. Including special kinematics and using properties of off-diagonal gluons at small $x$ and $ξ$ we arrive to correlations in two-dimensional distributions in rapidity of one and second jet. We find that the second contribution is much smaller than that known from the literature. The digluon production constitutes an important background to exclusive Higgs production.

Activity-based and Behavior-based Location Recommendation in Location Based Social Networks

subject: Cold-start problem

description: Location-Based Social Networks (LBSNs) are social networks with functionalities that let users share their location information with other users. Location recommendation is the task of suggesting unvisited locations to the users. A good location recommender should make user-specific recommendations based on users’ preferences, geographical constraints and time. In this thesis we investigate the development of two novel location recommendation methods for Location-Based Social Networks (LBSNs), the Probabilistic Category-based Location Recommender (PCLR) and the Behavior-based Location Recommender (BLR). The PCLR method finds the temporal and spatial patterns of users’ activities in the form of temporal and spatial probability distributions. It then uses the patterns to select the right category of locations and recommend nearby locations of that type to the user. On the other hand, the BLR method first extracts user behaviors from their check-in history. It then utilizes a collaborative filtering technique to extract common behaviors and predict behavior of the user at a given time. Finally, BLR filters locations in the user’s proximity based on the predicted behavior when making the location recommendation. PCLR and BLR methods go through a set of experiments on a real-world check-in dataset. These experiments show that PCLR and BLR methods improve the performance of the existing location recommenders in terms of precision and recall. Additionally, the BLR method produces much better recommendations for the cold-start users.

description: We discuss the bounds on the cosmological lepton number from Big Bang Nucleosynthesis (BBN), in light of recent evidences for a large value of the neutrino mixing angle theta13. The largest asymmetries for electron and muon or tau neutrinos compatible with 4He and 2H primordial yields are computed versus the neutrino mass hierarchy and mixing angles. The flavour oscillation dynamics is traced till the beginning of BBN and neutrino distributions after decoupling are numerically computed. The latter contains in general, non thermal distortion due to the onset of flavour oscillations driven by solar squared mass difference in the temperature range where neutrino scatterings become inefficient to enforce thermodynamical equilibrium. Depending on the value of theta13, this translates into a larger value for the effective number of neutrinos, N_eff. Upper bounds on this parameter are discussed for both neutrino mass hierarchies. Values for N_eff which are large enough to be detectable by the Planck experiment are found only for the (presently disfavoured) range sin^2(theta13)<0.01.

Dynamics of localized particles from density functional theory

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: A fundamental assumption of the dynamical density functional theory (DDFT) of colloidal systems is that a grand-canonical free energy functional may be employed to generate the thermodynamic driving forces. Using one-dimensional hard-rods as a model system we analyze the validity of this key assumption and show that unphysical self-interactions of the tagged particle density fields, arising from coupling to a particle reservoir, are responsible for the excessively fast relaxation predicted by the theory. Moreover, our findings suggest that even employing a canonical functional would not lead to an improvement for many-particle systems, if only the total density is considered. We present several possible schemes to suppress these effects by incorporating tagged densities. When applied to confined systems we demonstrate, using a simple example, that DDFT neccessarily leads to delocalized tagged particle density distributions, which do not respect the fundamental geometrical contraints apparent in Brownian dynamics simulation data. The implication of these results for possible applications of DDFT to treat the glass transition are discussed.

description: The network reconstruction task aims to estimate a complex system's structure from various data sources such as time series, snapshots, or interaction counts. Recent work has examined this problem in networks whose relationships involve precisely two entities-the pairwise case. Here we investigate the general problem of reconstructing a network in which higher-order interactions are also present. We study a minimal example of this problem, focusing on the case of hypergraphs with interactions between pairs and triplets of vertices, measured imperfectly and indirectly. We derive a Metropolis-Hastings-within-Gibbs algorithm for this model and use the algorithms to highlight the unique challenges that come with estimating higher-order models. We show that this approach tends to reconstruct empirical and synthetic networks more accurately than an equivalent graph model without higher-order interactions.

description: The structural performance of a novel hybrid precast concrete truss bridge girder proposed by Elbadry (2002) is experimentally investigated in this research. This new corrosion-resistant structural system benefits from the best characteristics of both fibre reinforced polymers (FRPs) and concrete combined in a hybrid form for construction of light and durable bridge structures. The composite bridge system comprises transversely spaced precast prestressed truss girders and a cast-in-place or precast concrete deck connected to the top of girders by means of shear connectors. The girders consist of top and bottom pretensioned concrete chords connected by vertical and diagonal concrete-filled FRP tube (CFFT) web members. The aim of this research is to experimentally investigate the structural behaviour of the proposed girder system under static and fatigue loading. A total of ten large-scale girder specimens were fabricated, of which four were tested under static loading, and six were tested under fatigue loading. The test results have shown excellent performance of the truss girders under both static and fatigue loading. Also, compression tests were performed on 69 CFFTs cast with different levels of expansive cement to evaluate its effects on the structural behaviour of the CFFTs. The tests showed significant increase in the confinement effectiveness and the load carrying capacity when expansive cement is added to the concrete mixture in CFFTs.

description: We propose a new approach to formally describing the requirement for statistical inference and checking whether a program uses the statistical method appropriately. Specifically, we define belief Hoare logic (BHL) for formalizing and reasoning about the statistical beliefs acquired via hypothesis testing. This program logic is sound and relatively complete with respect to a Kripke model for hypothesis tests. We demonstrate by examples that BHL is useful for reasoning about practical issues in hypothesis testing. In our framework, we clarify the importance of prior beliefs in acquiring statistical beliefs through hypothesis testing, and discuss the whole picture of the justification of statistical inference inside and outside the program logic.

Distributed Optimal Secondary Frequency Control in Power Networks with Delay Independent Stability

Subjects: subject: Optimization and Control (math.OC)

description: Distributed secondary frequency control for power systems, is a problem that has been extensively studied in the literature, and one of its key features is that an additional communication network is required to achieve optimal power allocation. Therefore, being able to provide stability guarantees in the presence of communication delays is an important requirement. Primal-dual and distributed averaging proportional-integral (DAPI) protocols, respectively, are two main control schemes that have been proposed in the literature. Each has its own relative merits, with the former allowing to incorporate general cost functions and additional operational constraints, and the latter being more straightforward in its implementation. Although delays have been addressed in DAPI schemes, there are currently no theoretical guarantees for the stability of primal-dual schemes for frequency control, when these are subject to communication delays. In fact, simulations illustrate that even small delays can destabilize such schemes. In this paper, we show how a novel formulation of prima-dual schemes allows to construct a distributed algorithm with delay independent stability guarantees. We also show that this algorithm can incorporate many of the key features of these schemes such as tie-line power flow requirements, generation constraints, and the relaxation of demand measurements with an observer layer. Finally, we illustrate our results through simulations on a 5-bus example and on the IEEE-39 test system.

Pre-colonial Irrigation and Settlement Patterns in Three Artificial Valleys in Lima – Peru

description: This investigation consist in the analysis of the southwest section of the lower Rimac River Valley, located in the Peruvian Central Coast, where three artificial valleys, generated by three main irrigation channels named La Magdalena, Maranga, and La Legua, originated from a single mother channel from the River. The objectives of this work were to establish the occupation sequence and settlement pattern in those artificial valleys in Precolonial times trying to shed some light into the origins of social complexity and the role of the irrigation systems in this process. Another main objective is to understand the main characteristics of Precolonial societies in the area, comparing them with the classic definitions from Neoevolutionary cultural anthropology: band, tribe, chiefdom and state that have been widely used by several scholars who worked on the Peruvian case. In order to reach those objectives, this investigation used modern and old maps and aerial photos in order to make a map of the area before the modern expansion of the city in the Twentieth Century that destroyed the irrigation systems and numerous archaeological sites, locally known as huacas. Several pottery collections from this area were analyzed in order to establish the chronology and cultural association of several archaeological sites. The investigation also comprised the analysis of colonial documents from the Sixteenth to the early Nineteenth centuries, some of them published and other kept in archives and libraries in Lima, trying to establish the political and territorial organization of the indigenous population in the late Precolonial period. This investigation found few elements that support the idea of an original emergence of state or the existence of urban settlements in the valley. The political organization seemed to be closer to the notion of simple and complex chiefdoms, with a hierarchy of lords controlling some sections of the artificial valley, during the Ancon (800-400 BC), Lima (300-800 AD) and Ychsma (1000-1476 AD) occupations, that were absorbed by expansive polities in some parts of their history: Janabarriu (Chavin) associated with the Ancon occupation, Topara (400 BC-300 AD), Wari (800-1000), and Inca (1476-1532).

description: Rank regression is a highly-efficient and robust approach to estimate regression coefficients and to make inference in the presence of outlying survival times. Heller (2007) developed a smoothed weighted rank regression function, which is used to estimate the regression parameter vector in an accelerated failure time model with right censored data. This function can be expressed as a U-statistic. However, since inference is based on a normal approximation approach, it could perform poorly when sample sizes are small and censoring rates are high. To increase inference accuracy and robustness, we propose a jackknife empirical likelihood method for the U-statistic obtained from the estimating function of Heller. The jackknife empirical likelihood ratio is shown to be a standard Chi-squared statistic. Simulations were conducted to compare the proposed method with the normal approximation method. As expected, the new method gives better coverage probability for small samples with high censoring rates. The Stanford Heart Transplant Data, Veterans Administration Lung Cancer Data and Multiple Myeloma Data sets are used to illustrate the proposed method.

Health behavior change as a primary healthcare intervention with special reference to physical therapists and smoking cessation
Creators: name: Bodner, Michael Eugene
Publisher: name: University of British Columbia
Year: 2010

description: Contemporary physical therapists have a professional responsibility to address lifestyle behavior risk factors related to the global burden of non-communicable chronic conditions. Smoking in particular is the leading cause of preventable death and disease and is a healthcare priority. An examination of the views, barriers and facilitators of physical therapists regarding smoking cessation interventions (including counseling), and assessment of health promotion in physical therapy curricula will form the basis to help advance this professional responsibility. Chapter Two describes national survey findings focusing on the knowledge of smoking health effects, and views, barriers, facilitators and practice patterns of Canadian physical therapists with respect to smoking cessation interventions, specifically smoking cessation counselling. Chapter Three examines the factors associated with the frequency that Canadian physical therapists counsel for smoking cessation. The key factors are high self efficacy and perceived preparedness to counsel and, to a lesser extent, professional views toward smoking cessation counselling and whether other members of physical therapists’ healthcare team also counsel. Chapter Four describes the elements of effective smoking cessation advice prescribed by health professionals in clinical settings derived from a systematic review and meta-analysis. Advice characterized as brief, intermediate or intensive is effective for helping smokers stop smoking and is advocated as a viable component congruent with physical therapy practice. Chapter Five describes findings from an international survey that examined the scope of health promotion related to lifestyle behavior risk factors, including content and instructional methodologies, in the curricula of entry-level physical therapy programs. Overall, health promotion is viewed as an important pillar of curricula. With the exception of exercise prescription, instructional methodologies related to practical applications and clinical competencies are not well represented as health topics. Chapter Six describes current gaps at the professional, practitioner, and educational levels with respect to health promotion as a primary healthcare intervention in physical therapy practice with specific focus on smoking and smoking cessation. We conclude that physical therapists could better align their professional values with their expertise and practices to address the health priorities of the 21st century with respect to health behavior change related to unhealthy lifestyle conditions, specifically smoking.

The result, in particular, implies that the Stokes operator in a three-dimensional Lipschitz domain generates a bounded analytic semigroup in $L^p$ for $(3/2)-\varep < p< 3+ε$. This gives an affirmative answer to a conjecture of M. Taylor.

description: In research concerning quantum networks, it is often assumed that the parties can classically communicate with each other. However, classical communication might introduce a substantial delay to the network, especially if it is large. As the latency of a network is one of its most important characteristics, it is interesting to consider quantum networks in which parties cannot communicate classically and ask what limitations this assumption imposes on the possibility of preparing multipartite states in such networks. We show that graph states of an arbitrary prime local dimension known for their numerous applications in quantum information cannot be generated in a quantum network in which parties are connected via sources of bipartite quantum states and the classical communication is replaced by some pre-shared classical correlations. We then generalise our result to arbitrary quantum states that are sufficiently close to graph states.

description: The coastal Atmospheric Boundary Layer (ABL) structure is subject of research in many countries as large number of cities and industrial activities are located onshore seas, oceans or lakes. Mean characteristics of ABL at a Bulgarian Black Sea coastal site are obtained based on unique long-term (August 2008 – October 2016) acoustic remote sensing measurements. Marine and land nocturnal air flow vertical profiles are studied. Exploring data of wind and turbulence profiles with high spatial (10 m) and temporal (10 min) resolution from SCINTEC MFAS sodar revealed typical parameters as the height of the Internal Boundary Layer (IBL), nocturnal ABL height over sea and land, etc. The seasonal variability of coastal ABL characteristics is explored. The reported results can be used for verification of theoretical, mesoscale and air quality models. The study contributes to the understanding of wind regime and turbulent structure of ABL in a region with modest observation networks and data near the surface and no measurements and data in vertical direction.

description: The mean values of reservoir parameters such as permeability, porosity, and hydrocarbon reserves are widely used to evaluate a formation for potential development and perform reservoir simulations. Among different mean estimators, the arithmetic average and Swanson’s rule are commonly used within the petroleum industry. In the petroleum literature, Swanson’s rule has been promoted as a superior alternative to the arithmetic average. A few researchers have evaluated its performance for the case of a log-normal distribution with a limited range of variability but they have overlooked its performance for other types of distribution, which may describe the distributions of reservoir parameters. Prior studies only concentrated on evaluating the bias of Swanson’s rule whereas an optimum mean estimator should simultaneously have zero bias, small uncertainty, consistency, and high efficiency. In addition to bias, this research study, thus, evaluates the performance of mean estimators based on these toher properties. This research study also compares the performance of Swanson’s rule with some well-known mean estimators: the arithmetic average, maximum likelihood estimator, and Pearson-Tukey’s rule for log normal and the power-normal and bimodal distributions. The mean estimators’ properties are analytically derived and numerically validated via Monte Carlo simulation. We find that none of these mean estimators simultaneously satisfies all conditions of an optimum mean estimator for all ranges of variability and sample size. In other words, each mean estimator can be an optimum mean estimator depending on sample size, variability, and distribution type. Being unbiased is a desirable property, but it is not necessarily the most important property because a mean estimator can be de-biased. We propose a de-biased version of Swanson’s rule and find it is an appropriate alternative for approximating the mean value, particularly for a data set with large standard deviation and small sample size. Moreover, we evaluate the performance of the mean estimators when data follow a first-order auto-regressive model to illustrate that the auto-correlation causes the mean estimators to behave differently compared to the uncorrelated case.
Wigner-Araki-Yanase theorem for continuous and unbounded conserved observables

description: The Wigner-Araki-Yanase (WAY) theorem states that additive conservation laws imply the commutativity of exactly implementable projective measurements and the conserved observables of the system. Known proofs of this theorem are only restricted to bounded or discrete-spectrum conserved observables of the system and are not applicable to unbounded and continuous observables like a momentum operator. In this Letter, we present the WAY theorem for possibly unbounded and continuous conserved observables under the Yanase condition, which requires that the probe positive operator-valued measure should commute with the conserved observable of the probe system. As a result of this WAY theorem, we show that exact implementations of the projective measurement of the position under momentum conservation and of the quadrature amplitude using linear optical instruments and photon counters are impossible. We also consider implementations of unitary channels under conservation laws and find that the conserved observable $L_S$ of the system commute with the implemented unitary $U_S$ if $L_S$ is semi-bounded, while $U_S^\dagger L_S U_S$ can shift up to possibly non-zero constant factor if the spectrum of $L_S$ is upper and lower unbounded. We give simple examples of the latter case, where $L_S$ is a momentum operator.

description: A web-based map viewer is developed within the European Horizon 2020 project MEET and intended as a one-stop solution to cater to the wide spectrum of stakeholders that are interested in deep geothermal exploration and project development. The webtool will support future users in the geothermal community to access geospatial data at European scale and to be able to identify and find existing geodata at national or smaller scales. At the culmination of the MEET project, the outcome of investigations at local scale (demo sites and analogue sites) will be transferred and upscaled to other potential regions all over Europe.
 The incorporated information ranges widely from traditional geological data to the information on the key players in geothermal sector. This webtool utilizes Opensource software like OpenLayers, PostGIS and GeoServer to produce the interactive data visualization. The data is grouped into different categories like geology, land and soil, environment, general information, powerplants etc. but can be effectively brought together by switching on multiple map layers and adjusting their transparency.
 We have aimed to fruitfully utilize the capabilities of Open Data while ensuring the trustworthiness by properly attributing thedata sources.
 We aim to combine this webtool with a decision-making tool which is another outcome of the MEET project. These, together with a parameter catalogue designed to offer more details about the various geothermal parameters would serve as a guiding trio for anyone who plans to deeply understand the landscape of geothermal energy sector in Europe.

description: In this paper, we characterise the smallest sets $B$ consisting of points and hyperplanes in $\text{PG}(n,q)$, such that each $k$-space is incident with at least one element of $B$. If $k > \frac {n-1} 2$, then the smallest construction consists only of points. Dually, if $k < \frac{n-1}2$, the smallest example consists only of hyperplanes. However, if $k = \frac{n-1}2$, then there exist sets containing both points and hyperplanes, which are smaller than any blocking set containing only points or only hyperplanes.
description: 7 pages. UPDATE: After publication of this paper, we found out that in case $k = \frac{n-1}2$, the correct lower bound and a classification of the smallest examples was already established by Blokhuis, Brouwer, and Sz\H{o}nyi [A.
