description: This paper presents a new fuzzy k-means algorithm for the clustering of high-dimensional data in various subspaces. Since high-dimensional data, some features might be irrelevant and relevant but may have different significance in the clustering process. For better clustering, it is crucial to incorporate the contribution of these features in the clustering process. To combine these features, in this paper, we have proposed a novel fuzzy k-means clustering algorithm by modifying the objective function of the fuzzy k-means using two different entropy terms. The first entropy term helps to minimize the within-cluster dispersion and maximize the negative entropy to determine clusters to contribute to the association of data points. The second entropy term helps control the weight of the features because different features have different contributing weights during the clustering to obtain a better partition. The proposed approach performance is presented in various clustering measures (AR, RI and NMI) on multiple datasets and compared with six other state-of-the-art methods. Impact Statement- In real-world applications, cluster-dependent feature weights help in partitioning the data set into more meaningful clusters. These features may be relevant, irrelevant, or redundant, but they each have different contributions during the clustering process. In this paper, a cluster-dependent feature weights approach is presented using fuzzy k-means to assign higher weights to relevant features and lower weights to irrelevant features during clustering. The method is validated using both supervised and unsupervised performance measures on real-world and synthetic datasets to demonstrate its effectiveness compared to state-of-the-art methods.

description: L’articolo intende sintetizzare e ampliare le riflessioni contenute nella ricerca di dottorato, recentemente discussa, dal titolo Città immaginate: il Pigneto-Prenestino e la sua fabbrica. Rigenerazione urbana e pratiche dal basso (Gissara, 2018).Il testo tratta sinteticamente le tematiche generali riguardanti l’insostenibilità dell’urbanizzazione contemporanea (sviluppo metropolitano, cambiamenti climatici, ‘diritto alla città’, ‘ricostruzione del territorio’, ecc.), per poi analizzarle nel concreto all’interno del contesto romano, individuando un luogo e un processo specifico da investigare.La scelta del caso-studio è conseguente al coinvolgimento diretto dell’autore nella battaglia locale per la riappropriazione popolare di un ex area produttiva, la fabbrica Snia Viscosa al Prenestino. Una lotta nata nei primi anni Novanta, quando un tentativo illegale di costruire un centro commerciale generò un evento imprevisto: la nascita di un lago naturale all’interno dello scavo di cantiere, quando le perforazioni rivelarono la presenza dimenticata di una falda in pressione. A seguito di ciò, la popolazione dei quartieri circostanti iniziò a rivendicare, nel contesto di un’urbanizzazione densa e inquinata, la destinazione dell’area a parco e servizi pubblici.La partecipazione e l’osservazione, negli ultimi anni, di questa battaglia locale auto-organizzata, così come le testimonianze riferite ai decenni precedenti, hanno restituito numerosi spunti di riflessione, riguardanti le condizioni passate, presenti e future di questo luogo e la ‘comunità di resistenza’ che si è riunita attorno ad esso. In particolare, sono emersi alcuni elementi importanti: l’approccio ecosistemico, il mix tra diverse conoscenze, le relazioni tra le persone.L’articolo vuole esplorare criticamente questi aspetti e, in conclusione, tornare a formulare considerazioni più ampie alla luce di tutti questi fattori, così da sottolineare l’esistenza di possibili percorsi alternativi all’urbanizzazione senza fine e alle conseguenti problematiche ambientali.

description: This contribution presents a backstepping-based state feedback design for the tracking control of a two-phase Stefan problem which is encountered in the Vertical Gradient Freeze crystal growth process. A two-phase Stefan problem consists of two coupled free boundary problems and is a vital part of many crystal growth processes due to the time-varying extent of crystal and melt during growth. In addition, a different approach for the numerical approximation of the backstepping transformations kernel is presented.

description: Linearization of a Hamiltonian system around an equilibrium point yields a set of Hamiltonian-symmetric spectra: If $λ$ is an eigenvalue of the linearized generator, $-λ$ and $\barλ$ (hence, $-\barλ$) are also eigenvalues -- the former implies a time-reversal symmetry, while the latter guarantees the reality of the solution. However, linearization around a singular equilibrium point (which commonly exists in noncanonical Hamiltonian systems) works out differently, resulting in breaking of the Hamiltonian symmetry of spectra; time-reversal asymmetry causes chirality. This interesting phenomenon was first found in analyzing the chiral motion of the rattleback, a boat-shaped top having misaligned axes of inertia and geometry [Phys. Lett. A 381 (2017), 2772--2777]. To elucidate how chiral spectra are generated, we study the 3-dimensional Lie-Poisson systems, and classify the prototypes of singularities that cause symmetry breaking. The central idea is the deformation of the underlying Lie algebra; invoking Bianchi's list of all 3-dimensional Lie algebras, we show that the so-called class-B algebras, which are produced by asymmetric deformations of the simple algebra so(3), yield chiral spectra when linearized around their singularities. The theory of deformation is generalized to higher dimensions, including the infinite-dimensional Poisson manifolds relevant to fluid mechanics.

description: We present a detailed \chandra study of the galaxy group NGC 1550. For its temperature (1.37$\pm$0.01 keV) and velocity dispersion ($\sim$ 300 km s$^{-1}$), the NGC 1550 group is one of the most luminous known galaxy groups (L$_{\rm bol}$ = 1.65$\times10^{43}$ erg s$^{-1}$ within 200 kpc, or 0.2 \rv). We find that within $\sim 60$ kpc, where the gas cooling time is less than a Hubble time, the gas temperature decreases continuously toward the center, implying the existence of a cooling core. The temperature also declines beyond $\sim$ 100 kpc (or 0.1 \rv). There is a remarkable similarity of the temperature profile of NGC 1550 with those of two other 1 keV groups with accurate temperature determination. The temperature begins to decline at 0.07 - 0.1 \rv, while in hot clusters the decline begins at or beyond 0.2 \rv. Thus, there are at least some 1 keV groups that have significantly different temperature profiles from those of hot clusters, which may reflect the role of non-gravitational processes in ICM/IGM evolution. NGC 1550 has no isentropic core in its entropy profile, in contrast to the predictions of `entropy-floor' simulations. We compare the scaled entropy profiles of three 1 keV groups (including NGC 1550) and three 2 - 3 keV groups. The scaled entropy profiles of 1 keV groups show much larger scatter than those of hotter systems, which implies varied pre-heating levels. We also discuss the mass content of the NGC 1550 group and the abundance profile of heavy elements.

description: The theory of quantum trajectories is applied to simulate the effects of quantum noise sources induced by the environment on quantum information protocols. We study two models that generalize single qubit noise channels like amplitude damping and phase flip to the many-qubit situation. We calculate the fidelity of quantum information transmission through a chaotic channel using the teleportation scheme with different environments. In this example, we analyze the role played by the kind of collective noise suffered by the quantum processor during its operation. We also investigate the stability of a quantum algorithm simulating the quantum dynamics of a paradigmatic model of chaos, the baker's map. Our results demonstrate that, using the quantum trajectories approach, we are able to simulate quantum protocols in the presence of noise and with large system sizes of more than 20 qubits.

description: The article chronicles the economic and social collapse of a once vibrant industrial city located along the banks of the Mississippi River. It describes how powerful deindustrialization, disinvestment, and suburbanization forces undermined the health of the East St. Louis, Illinois economy and municipal government leaving the city’s 40,000 residents without such basic municipal services as: street lighting and garbage collection for eight years. What distinguishes this story is the emergence of a small group of low-income African American women who responded to the failures of their municipal government by self-organizing a “bottom-up, bottom-sideways” planning, and development process. This article describes how these women, with the assistance of students and faculty from the University of Illinois at Urbana-Champaign, worked together to generate more than $200 million in new investment which stabilized their neighborhood and encouraged others to undertake similar resident-led planning efforts. Along the way, this unlikely “partnership” involving grassroots leaders, municipal officials, and university scholars developed a new model of community development. Their empowerment planning approach to urban development integrates key principles and methods of participatory action research (PAR), direct action organizing (DAO), and popular education into a highly effective urban transformation process that has subsequently been replicated in many other economically distressed communities.

description: Starting from Gauss and Kelvin, knots in fields were postulated behaving like particles, but experimentally they were found only as transient features or required complex boundary conditions to exist and couldn't self-assemble into three-dimensional crystals. We introduce energetically stable micrometer-sized knots in helical fields of chiral liquid crystals. While spatially localized and freely diffusing in all directions, they resemble colloidal particles and atoms, self-assembling into crystalline lattices with open and closed structures. These knots are robust and topologically distinct from the host medium, though they can be morphed and reconfigured by weak stimuli under conditions like in displays. A combination of energy-minimizing numerical modeling and optical imaging uncovers the internal structure and topology of individual helical field knots and various hierarchical crystalline organizations they form.

description: The Epps effect is key phenomenology relating to high frequency correlation dynamics in financial markets. We argue that it can be used to provide insight into whether tick data is best represented as samples from Brownian diffusions, or as samples from truly discrete events represented as connected point processes. We derive the Epps effect arising from asynchrony and provide a refined method to correct for the effect. We then propose three experiments which show how to discriminate between possible underlying representations. These in turn demonstrate how a simple Hawkes representation recovers phenomenology reported in the literature that cannot be recovered using a Brownian representation without additional ad hoc model complexity. However, complex ad hoc noise models built on Brownian motions cannot in general be discriminated relative to a Hawkes representation. Nevertheless, we argue that high frequency correlation dynamics are most faithfully recovered when tick data is represented as a web of interconnected discrete events rather than being samples from continuous Brownian diffusions even when combined with noise.

description: The polytope subalgebra of deformations of a zonotope can be endowed with the structure of a module over the Tits algebra of the corresponding hyperplane arrangement. We explore this construction and find relations between statistics on (signed) permutations and the module structure in the case of (type B) generalized permutahedra. In type B, the module structure surprisingly reveals that any family of generators (via signed Minkowski sums) for generalized permutahedra of type B will contain at least $2^{d-1}$ full-dimensional polytopes. We find a generating family of simplices attaining this minimum. Finally, we prove that the relations defining the polytope algebra are compatible with the Hopf monoid structure of generalized permutahedra.

description: The nonlinear interaction, due to quantum electrodynamical (QED) effects, between an electromagnetic pulse and a radiation background is investigated, by combining the methods of radiation hydrodynamics with the QED theory for photon-photon scattering. For the case of a single coherent electromagnetic pulse we obtain a Zakharov-like system, where the radiation pressure of the pulse acts as a driver of acoustic waves in the photon gas. For a sufficiently intense pulse and/or background energy density there is focusing and subsequent collapse of the pulse. The relevance of our results for various astrophysical applications are discussed.

Simultaneous solution to B --> phi K CP Asymmetry and B --> eta(prime) K, eta K^* branching ratio anomalies from R-parity violation

description: The branching ratios for the neutral and charged B decay channels to $η' K$ and $ηK^*$ are well above the Standard Model expectations. Moreover, the mixing-induced CP asymmetry in $B \to ϕK_S$ is incompatible to that found in $B\to J/ψK_S$. We investigate whether a flavour-specific tree-level $b\to s \bar{s} s$ operator coming from R-parity violating supersymmetry can resolve both these discrepancies, without jeopardizing those results which are in agreement with the Standard Model. We found that it is possible to have a parameter space satisfying all these requirements, including that of a low strong phase difference compatible with the color transparency argument. Furthermore, we put a robust bound on the relevant coupling, which is two orders of magnitude better than the existing one.

description: By exploring different cultural roots of self-organisation, the paper points out and discusses the lights and shadows of a concept, which is increasingly used both in mainstream theories and in critical thinking.

In so doing, the contribution aims at offering a basic framework for containing and giving sense to the various approaches to self-organization (as they emerge from the two issues of Tracce Urbane, n. 3 and 4, dedicated to that topic), yet sufficiently structured to allow orientation among the variants in which the concept is used in relation with the city. The intent is, therefore, also methodological, and concerns the consistence between theories and concepts, and the heuristics we adopt to analyse and explain spatial phenomena and practices.

description: We derive a t-J model with electron-phonon coupling from the three-band model, considering modulation of both hopping and Coulomb integrals by phonons. While the modulation of the hopping integrals dominates, the modulation of the Coulomb integrals cannot be neglected. The model explains the experimentally observed anomalous softening of the half-breathing mode upon doping and a weaker softening of the breathing mode. It is shown that other phonons are not strongly influenced, and, in particular, the coupling to a buckling mode is not strong in this model.

title: Electromagnetic Wearable Sensors: A Solution to Non-Invasive Real-Time Monitoring of Biological Markers during Exercise
Creators: name: Greene, J
Publisher: name: Liverpool John Moores University
Year: 2021

description: Wearable sensing technology holds the potential to provide greater insights into the performance and health status of athletes during exercise that are currently unattainable traditional laboratory-based techniques. The process of collecting accurate data from complex metabolic parameters often requires adapted equipment and methods that are often expensive and invasive. This project aims to investigate the novel use of a non-invasive purpose-built electromagnetic (EM) sensor operating at microwave frequencies, examining whether the EM sensor is capable of detecting and monitoring the physiological responses of three chosen parameters, sweat sodium, blood lactate, and skeletal muscle glycogen in humans during exercise. These parameters are selected based on their significance to elite athletic monitoring, as well as the current methods of analysis being impractical for real-time monitoring during exercise. Four human studies and two in-vitro sample-based studies were conducted, accumulating in 140 sweat samples, 523 blood lactate samples and 21 glycogen samples from a combined total of 71 participants, 56 males, and 15 females. The work presented in this thesis demonstrated that a hairpin microwave sensor can monitor changes in sodium concentration in human sweat samples at 1.6GHz (R2 = 0.862), blood lactate in untrained participants at 3.4-3.6 GHz (R2 = 0.78) and endurance trained participants at 3.2-3.8 GHz (R2 = 0.757). Furthermore, it was shown to monitor changes in glycogen samples at 2.11 GHz (R2 = 0.87), as well as skeletal muscle glycogen measurements in humans, when grouped into exercise specific ranges at 2.0-2.25 GHz (R2 = 0.91). Further development is required for real-time on-subject application of the microwave sensor to monitor sweat sodium during exercise (R2 = 0.149), due to the microwave sensor’s design limitations, rather than sensing capabilities. This research presents an accurate, cost effective, and efficient method to detect biomarkers in athletes non-invasively and continuously during exercise. This capability would facilitate accurate monitoring of physical activity and enable effective fuelling strategies for athletes during training and competition, thus improving performance and reducing the associated health risks. Future investigations are required to validate each frequency range and to identify the penetration depth capability when subcutaneous tissue is increased. Finally, assessment this technology within a real-world environment is needed to ensure it is a feasible solution outside of a controlled laboratory setting.

description: This paper is a summary of: Rafael de Farias Costa, C. Parr Rosson, III, and Flynn J. Adcock, Transportation Infrastructure in Brazil: Impacts and Implications for Global Cotton Trade, Texas A&M, CNAS 2012-0. May 2012. Web. Brazil is the third largest cotton exporter after the United States and Uzbekistan. Cotton production in Brazil expanded from 2 million bales in the late 1990s to about 9.3 million bales in 2011. In 2007, Brazil began a comprehensive logistical investment plan to increase competitiveness in the world agricultural market. To increase transportation efficiencies, the Brazilian Government wants to reduce export route distances and port congestion by shifting exports from the southern ports to the north and northeast port regions. Texas AgriLIFE Research scientists estimated the impact of Brazil improvements in transportation infrastructure on cotton production, prices, and exports. Transportation costs for different regions within Brazil were estimated to reflect movements from mill to port. An origin-destination matrix of the Brazilian cotton industry that tracks cotton flows within the country was developed and validated. Findings indicate that a 2- to 3-percent transportation cost reduction would not have a significant impact on the world cotton trade. However, the United States may benefit slightly Brazil main cotton export routes from a 2-percent cost reduction, increasing exports by 640 bales, raising prices 2 cents a bale, and growing revenue by $457,900. If transportation costs drop by 10 percent, Brazilian exports could increase by 64,830 bales, raising prices by $3.61 per bale and increasing revenue by $27.8 million. India and the United States might lose market share. U.S. losses could include 4,490 fewer bales exported at a price of $0.28 less per bale and lower cotton export revenues of $5.7 million.

description: Detection of small-sized targets is of paramount importance in many aerial vision-based applications. The commonly deployed low cost unmanned aerial vehicles (UAVs) for aerial scene analysis are highly resource constrained in nature. In this paper we propose a simple short and shallow network (SSSDet) to robustly detect and classify small-sized vehicles in aerial scenes. The proposed SSSDet is up to 4x faster, requires 4.4x less FLOPs, has 30x less parameters, requires 31x less memory space and provides better accuracy in comparison to existing state-of-the-art detectors. Thus, it is more suitable for hardware implementation in real-time applications. We also created a new airborne image dataset (ABD) by annotating 1396 new objects in 79 aerial images for our experiments. The effectiveness of the proposed method is validated on the existing VEDAI, DLR-3K, DOTA and Combined dataset. The SSSDet outperforms state-of-the-art detectors in term of accuracy, speed, compute and memory efficiency.

description: Non-classical non-linear waves exist in dense gases for large specific heats at pressures and temperatures of the order of critical point values. These waves behave precisely opposite to the classical non-linear waves, with inverted classical waves like the expansion shocks which do not violate entropy conditions. More complex equation of state (EOS) other than the ideal or perfect EOS is typically used in describing dense gases. Algorithm development with non-ideal/real gas EOS and application to dense gasses is gaining importance from a numerical perspective. Extending the algorithms designed for perfect gas EOS to dense gas flows with arbitrary real gas EOS is non-trivial. Most of the algorithms designed for prefect gas EOS are modified significantly when applied to real gas EOS. These algorithms can become complicated and some times impossible based on the EOS under consideration. The objective of the present work is to develop central solvers with smart diffusion capabilities independent of the eigenstructure and extendable to any arbitrary EOS. Euler equations with van der Waals EOS along with two newly developed algorithms, Method of Optimal Viscosity for Enhanced resolution of shocks (MOVERS+) and Riemann Invariants based Contact capturing Algorithm (RICCA), are used to simulate dense gasses over simple geometries. Various One Dimensional (1D) and Two Dimensional (2D) benchmark test cases are validated using these algorithms, and the results are compared with the those obtained from the literature.

description: Il saggio, a partire da una ricostruzione storica dell’importante ruolo svolto dai processi di autoorganizzazione nella costruzione delle forme di territorialità e nella produzione dei contesti urbani, individua nell’affermarsi della visione cartografica e nell’emergere dell’organizzazione dello Stato moderno i passaggi chiave attraverso cui prende l’avvio un nuovo modo di guardare al territorio. È a partire da questo momento, infatti, che il territorio, prima considerato come un organismo complesso, fatto da realtà autoorganizzate, comincia ad essere trattato come una superficie vuota su cui far calare dall’alto un progetto interamente pensato o una legge elaborati da un soggetto astratto e impersonale. Nel decostruire le premesse fondate ma infondantiin cui questa visione del mondo, affonda le sue stesse basi, il saggio invita a guardare con attenzione le nuove pratiche autoorganizzative che emergono nei territori contemporanei.

description: In a recent paper, Backelin, West and Xin describe a map $ϕ^*$ that recursively replaces all occurrences of the pattern $k... 21$ in a permutation $σ$ by occurrences of the pattern $(k-1)... 21 k$. The resulting permutation $ϕ^*(σ)$ contains no decreasing subsequence of length $k$. We prove that, rather unexpectedly, the map $ϕ^*$ commutes with taking the inverse of a permutation. In the BWX paper, the definition of $ϕ^*$ is actually extended to full rook placements on a Ferrers board (the permutations correspond to square boards), and the construction of the map $ϕ^*$ is the key step in proving the following result. Let $T$ be a set of patterns starting with the prefix $12... k$. Let $T'$ be the set of patterns obtained by replacing this prefix by $k... 21$ in every pattern of $T$. Then for all $n$, the number of permutations of the symmetric group $\Sn_n$ that avoid $T$ equals the number of permutations of $\Sn_n$ that avoid $T'$. Our commutation result, generalized to Ferrers boards, implies that the number of {\em involutions} of $\Sn_n$ that avoid $T$ is equal to the number of involutions of $\Sn_n$ avoiding $T'$, as recently conjectured by Jaggard.

title: Maximizing Health and Safety and Reducing COVID Transmission at Old Dominion University with Standard Operating Procedures (SOP) Approach
Creators: name: Nadeem, Hira
Publisher: name: Old Dominion University Libraries
Year: 2021

description: Due to the COVID19 pandemic, the school system in United Stated has been struggling to reopen the campus at full capacity and keep students safe. Old Dominion University (ODU) in Norfolk, Virginia, currently faces the COVID-19 pandemic with virtual classes, meetings, student engagement, and keeping on-campus students safe. With weekly testing offered at the dorms, on-campus students can contract COVID and become positive. In the Hampton Roads area, the Norfolk positivity rate for COVID is 15.7% as of February 1st. To combat and contain COVID for on-campus and returning students, ODU created the COVID Care Team who assist students and departments to operate safely in time of COVID19 positive student. With this team's creation, ODU was ranked as one of the safest campuses during this pandemic throughout all Virginia colleges
Thin accretion disk around the distorted Schwarzschild black hole

description: We construct the relativistic standard steady, optically thick, cold and geometrically thin accretion disk around a distorted Schwarzschild black hole. The distortion of this static and axially symmetric black hole solution, is connected to an external distribution of matter. If the effects due to the rotation are negligible, this distribution can describe the exterior of any axially symmetric astrophysical model. Also, the distortion could be related to the outer parts of the accretion disk. We study the effects due to a distortion up to the quadrupole, and compare the physical characteristics of this disk to the usual Schwarzschild case.

description: We compute the gravitational radiation generated in the evolution of a family of close binary black hole configurations, using a combination of numerical and perturbative approximation methods. We evolve the binaries with spins, $s$, aligned or counter-aligned with the orbital angular momentum from near the innermost stable circular orbit (ISCO) down to the final single rotating black hole. For the moderately spinning holes studied here the remnant Kerr black hole formed at the end of an inspiral process have a rotation parameter $a/M\approx0.72+0.32(s/m_H)$, suggesting it is difficult (though not excluded) to end up with near maximally rotating holes from such scenarios.

Cheese Pricing in a Market Driven Environment

description: I want to thank the Subcommittees for inviting me to present some insights and suggestions on how to improve the integrity and efficiency of cheese pricing in the United States. As these Subcommittees well know the reduction in government support prices means that market forces and market institutions now play a significantly larger role in the price discovery process for cheese and manufacturing milk. As government regulation is reduced in any industry, from telecommunications to milk, one must expand antitrust and other market monitoring activities to ensure that effective competition prevails. In some cases one must consider public intervention not to set prices, but to set the rules and boundaries of the pricing game.

description: In this paper, we present results on strong two-body decay widths of light $q\bar q$ mesons calculated in a covariant quark model. The model is based on the Bethe-Salpeter equation in its instantaneous approximation and has already been used for computing the complete meson mass spectrum and many electroweak decay observables. Our approach relies on the use of a phenomenological confinement potential with an appropriate spinorial Dirac structure and 't Hooft's instanton--induced interaction as a residual force for pseudoscalar and scalar mesons. The transition matrix element for the decay of one initial meson into two final mesons is evaluated in lowest order by considering conventional decays via quark loops as well as Zweig rule violating instanton--induced decays generated by the six--quark vertex of 't Hooft's interaction; the latter mechanism only contributes if all mesons in the decay have zero total angular momentum. We show that the interference of both decay mechanisms plays an important role in the description of the partial widths of scalar and pseudoscalar mesons.

description: We compute the Renormalization Group functions of a Landau-Ginzburg-Wilson Hamiltonian with O(n)x O(m) symmetry up to five-loop in Minimal Subtraction scheme. The line n^+(m,d), which limits the region of second-order phase transition, is reconstructed in the framework of the epsilon=4-d expansion for generic values of $m$ up to O(epsilon^5). For the physically interesting case of noncollinear but planar orderings (m=2) we obtain n^+(2,3)=6.1(6) by exploiting different resummation procedures. We substantiate this results re-analyzing six-loop fixed dimension series with pseudo-epsilon expansion, obtaining n^+(2,3)=6.22(12). We also provide predictions for the critical exponents characterizing the second-order phase transition occurring for n>n^+.
