"Effect Of Whole-Body Vibration on Dynamic Balance and Core Strength in Bharatnatyam Dancers: An Experimental Study"
Creators: name: Mayuresh

name: S Jeyakumar
Publisher: name: Zenodo
Year: 2025

description: Background: Bharatanatyam, a classical Indian dance form, requires exceptional core strength and dynamic balance due to its complex postures and movements. Traditional training methodologies may inadequately address the specific balance and strength needs of dancers, potentially leading to musculoskeletal issues and performance limitations. Whole-Body Vibration (WBV) has demonstrated efficacy in enhancing neuromuscular function, yet its impact on Bharatanatyam dancers remains insufficiently investigated. This study aims to address this gap by evaluating the potential benefits of WBV on core strength and dynamic balance within this specific population.Objective and Purpose: The objective of this study was to assess the effects of WBV training on dynamic balance and core strength in Bharatanatyam dancers. The purpose was to ascertain whether WBV could serve as an effective adjunct to traditional training methods for achieving expedited improvements in these physical attributes.Methods: An experimental design was utilized involving 50 Bharatanatyam dancers who underwent a 4-week WBV intervention. The training protocol comprised WBV sessions at frequencies ranging from 50 to 60 Hz for 20 minutes, conducted three times per week, supplemented with targeted exercises. Core strength was evaluated using pressure biofeedback, while dynamic balance was measured using the Y-Balance Test, both pre- and post-intervention.Results: The intervention yielded a statistically significant enhancement in core strength, with a mean increase of 32.62% (p < 0.0001). Dynamic balance also showed significant improvement, with mean reach distances increasing by 11.6% across all assessed directions (p < 0.001). These findings indicate that WBV training effectively augments both core strength and dynamic balance in Bharatanatyam dancers.Conclusion: WBV training substantially enhances core strength and dynamic balance in Bharatanatyam dancers within a relatively short duration. These results suggest that WBV represents a promising supplement to conventional training methods, offering a rapid approach to improving performance and stability. Further studies with larger and more varied samples are warranted to validate these outcomes and explore broader applications.

description: Molecular dynamics simulations have been employed to study the formation of a physical (thermoreversible) gel by amphiphilic A-B-A triblock copolymers in aqueous solution. In order to mimic the structure of hydrogel-forming polypeptides employed in experiments [W.A. Petka et al., Science 281, 389 (1998)], the endblocks of the polymer chains are modeled as hydrophobic rods representing the alpha-helical part of the polypeptides whereas the central B-block is hydrophilic and semi-flexible. We have determined structural properties, such as the hydrophobic cluster-size distribution function, the geometric percolation point and pair correlation functions, and related these to the dynamical properties of the system. Upon decrease of the temperature, a network structure is formed in which bundles of endblocks act as network junctions. Both at short and medium distances an increased ordering is observed, as characterized by the pair correlation function. Micelle formation and the corresponding onset of geometric percolation induce a strong change in dynamical quantities, e.g., in the diffusion constant and the viscosity, and causes the system to deviate from the Stokes-Einstein relation. The dynamical properties show a temperature dependence that is strongly reminiscent of the behavior of glass-forming liquids. The appearance of a plateau in the stress autocorrelation function suggests that the system starts to exhibit a solid-like response to applied stress once the network structure has been formed, although the actual sol-gel transition occurs only at a considerably lower temperature.

description: O objetivo deste estudo foi identificar os fatores de inadimplência dos produtores inseridos nas áreas de concentração de fruteiras no Estado do Ceará e comparar a inadimplência da agricultura irrigada com a sequeiro. Para identificar os fatores da inadimplência utilizou-se um modelo econométrico – PROBIT. Os resultados mostraram que os principais fatores da inadimplência nas áreas de concentração de fruteiras no Estado do Ceará foram: nível de escolaridade, uso de irrigação, não participação do produtor na elaboração do projeto, inobservância dos princípios básicos do crédito rural (oportunidade, adequação e suficiência) e receitas obtidas abaixo do esperado. Sugere-se, assim uma política mais efetiva para a fruticultura, atrelada à capacitação dos produtores; tornar a irrigação, com ênfase nos mini e pequenos produtores, mais organizada e articulada, de modo a transformar essa prática agrícola em um dos instrumentos de melhoria de rentabilidade da atividade; fomentar a organização dos produtores (associação ou cooperativa), baseado nas experiências exitosas, para as áreas concentradoras de fruteiras do Estado e desenvolver estratégias visando 2 contemplar os fruticultores que estiverem fora do perfil adequado, uma vez que o crédito rural constitui um dos instrumentos de diversificação e modernização da fruticultura.

description: This paper is a direct generalization of Baker-Bowler theory to flag matroids, including its moduli interpretation as developed by Baker and the second author for matroids. More explicitly, we extend the notion of flag matroids to flag matroids over any tract, provide cryptomorphic descriptions in terms of basis axioms (Grassmann-Plücker functions), circuit/vector axioms and dual pairs, including additional characterizations in the case of perfect tracts. We establish duality of flag matroids and construct minors. Based on the theory of ordered blue schemes, we introduce flag matroid bundles and construct their moduli space, which leads to algebro-geometric descriptions of duality and minors. Taking rational points recovers flag varieties in several geometric contexts: over (topological) fields, in tropical geometry, and as a generalization of the MacPhersonian.

description: Fashion manipulation has attracted growing interest due to its great application value, which inspires many researches towards fashion images. However, little attention has been paid to fashion design draft. In this paper, we study a new unaligned translation problem between design drafts and real fashion items, whose main challenge lies in the huge misalignment between the two modalities. We first collect paired design drafts and real fashion item images without pixel-wise alignment. To solve the misalignment problem, our main idea is to train a sampling network to adaptively adjust the input to an intermediate state with structure alignment to the output. Moreover, built upon the sampling network, we present design draft to real fashion item translation network (D2RNet), where two separate translation streams that focus on texture and shape, respectively, are combined tactfully to get both benefits. D2RNet is able to generate realistic garments with both texture and shape consistency to their design drafts. We show that this idea can be effectively applied to the reverse translation problem and present R2DNet accordingly. Extensive experiments on unaligned fashion design translation demonstrate the superiority of our method over state-of-the-art methods.

description: Este trabalho apresenta os principais resultados de pesquisa de campo, realizada de em uma amostra de 229 (duzentos e vinte e nove) produtores de frangos de corte dos principais estados produtores do Brasil. Com esse instrumento de pesquisa básica, identificam-se as principais variáveis econômicas, sociais e ambientais visando à caracterização dos produtores, de acordo com as regiões onde estão inseridos. Esta caracterização sócio-econômica dos produtores de frango de corte se configura a partir da identificação de uma região tradicional produtora, compreendendo os estados do Rio Grande do Sul, Paraná, Santa Catarina e Minas Gerais e de uma região de expansão abrangendo os estados do Mato Grosso do Sul, Mato Grosso e Goiás. Conclui-se que a amostra de produtores de frango pesquisada representa bem as realidades regionais, com o predomínio de produtores com pequenas propriedades e menor capacidade produtiva no Sul do país e Minas Gerais e produtores com propriedades maiores e níveis de produção mais elevados nos estados do Centro-Oeste brasileiro. Nas regiões Oeste do Paraná e no Triângulo Mineiro (regiões tradicionais produtoras de soja e milho) encontramos os produtores com maiores áreas de terra e com as maiores capacidades de alojamento de aves da amostra da região tradicional. No Centro-Oeste, os produtores visitados no estado do Mato Grosso do Sul foram os que apresentaram menores áreas de terra e menores estratos de capacidade de produção de frangos de corte, enquanto os produtores pesquisados do estado de Goiás foram os que apresentaram os maiores estratos de capacidade de produção da região.

description: O conhecimento do perfil do consumidor dos produtos orgânicos comercializados pela Associação para o Desenvolvimento da Agropecuária Orgânica – ADAO, gera um importante instrumento de marketing visando à consolidação da produção de produtos orgânicos e permite responder à crescente demanda por produtos orgânicos no Ceará, determinando a adequação da produção e comercialização às exigências dos consumidores no que se refere à quantidade, qualidade e variedade dos produtos. O presente estudo objetivou caracterizar o consumo de produtos orgânicos comercializados pela ADAO. Na caracterização do perfil do consumidor observou-se que a maior parte dos consumidores de produtos orgânicos é de mulheres, casadas, com filhos, idade acima de cinqüenta anos, com nível superior de escolaridade e renda acima e dez salários mínimos. A decisão do consumo de produtos orgânicos traz melhoria nas condições de saúde. Os produtos mais procurados são as verduras e os legumes. O consumo geral dos produtos orgânicos apresentou uma tendência positiva de crescimento. Apesar de se tratar de um estudo de caso, os resultados obtidos podem ser utilizados por produtores e varejistas para a conquista de novos consumidores. Deve-se investir em campanhas para a conscientização sobre os danos causados por agentes químicos à saúde, utilizados na produção agrícola convencional.

description: This paper deals with the detection of mu-suppression from electroencephalographic (EEG) signals in brain-computer interface (BCI). For this purpose, an efficient algorithm is proposed based on a statistical model and a linear classifier. Precisely, the generalized extreme value distribution (GEV) is proposed to represent the power spectrum density of the EEG signal in the central motor cortex. The associated three parameters are estimated using the maximum likelihood method. Based on these parameters, a simple and efficient linear classifier was designed to classify three types of events: imagery, movement, and resting. Preliminary results show that the proposed statistical model can be used in order to detect precisely the mu-suppression and distinguish different EEG events, with very good classification accuracy.

description: Large intrinsic anomalous Hall effect (AHE) originating in the Berry curvature has attracted growing attention for potential applications. Recently proposed magnetic Weyl semimetal EuCd$_2$Sb$_{\mathrm{2}}$ provides an excellent platform for controlling the intrinsic AHE because it only hosts a Weyl-points related band structure near the Fermi energy. Here we report the fabrication of EuCd$_2$Sb$_{\mathrm{2}}$ single-crystalline films and control of their anomalous Hall effect by film technique. As also analyzed by first-principles calculations of energy-dependent intrinsic anomalous Hall conductivity, the obtained anomalous Hall effect shows a sharp peak as a function of carrier density, demonstrating clear energy dependence of the intrinsic AHE.

description: Este artigo analisa aspectos alocativos e distributivos de uma política de redução dos tributos indiretos sobre os principais insumos utilizados na atividade agropecuária. A análise é realizada com o uso de um modelo aplicado de equilíbrio geral inter-regional para a economia brasileira calibrado para o ano de 2001. Os resultados da simulação de redução pela metade nas alíquotas de tributos indiretos sobre tais insumos mostram aumento no nível de atividade econômica nas regiões mais pobres do País e têm o potencial de melhorar o poder de compra dos grupos de rendas mais baixas em todas as regiões, especialmente nas mais pobres: Norte e Nordeste. Os resultados sugerem que políticas tributárias como esta pode, ao mesmo tempo, promover um crescimento no nível de atividade econômica e melhorar a distribuição de renda, especialmente nas regiões mais pobres do País. O impacto negativo sobre a arrecadação dos governos revela-se como a principal restrição à implementação dessa política. Os resultados encontrados revelam também a grande utilidade dos modelos aplicados de equilíbrio geral interregional para análise dos impactos de políticas tributárias no Brasil.

description: The generalized L'vov-Kaplansky conjecture states that for any finite-dimensional simple algebra $A$ the image of a multilinear polynomial on $A$ is a vector space. In this paper we prove it for the algebra of octonions $\mathbb{O}$ over a field satisfying certain specified conditions (in particular, we prove it for quadratically closed field and for field $\mathbb{R}$).
 In fact, we prove that the image set must be either $\{0\}$, $F$, the space of pure octonions $V$, or $\mathbb{O}$. We discuss possible evaluations of semihomogeneous polynomials on $\mathbb{O}$ and of arbitrary polynomials on the corresponding Malcev algebra.

description: Charge and spin current correlations are analyzed in a source of spin-entangled electrons built from a superconductor and two quantum dots in parallel. In addition to the ideal (crossed Andreev) channel, parasitic channels (direct Andreev and cotunneling) and spin flip processes are fully described in a density matrix framework. The way they reduce both the efficiency and the fidelity of the entangler is quantitatively described by analyzing the zero-frequency noise correlations of charge current as well as spin current in the two output branches. Spin current noise is characterized by a spin Fano factor, equal to 0 (total current noise) and -1 (crossed correlations) for an ideal entangler. The violation of the Bell inequalities, as a test of non-locality (entanglement) of split pairs, is formulated in terms of the correlations of electron charge and spin numbers counted in a specific time window $τ$. The efficiency of the test is analyzed, comparing $τ$ to the various time scales in the entangler operation.

description: We explore $\mathcal{N}=1$ supersymmetric extensions of algebras going beyond the Poincaré and AdS ones in three spacetime dimensions. Besides reproducing two known examples, we present new superalgebras, which all correspond to supersymmetric extensions with one fermionic charge $Q_α$ concerning the so-called resonant algebras being characterized by the presence of an additional bosonic generator $Z_{a}$, besides the Lorentz $J_{a}$ and translation $P_{a}$ generators. Obtained eight supersymmetric $JPZ+Q$ schemes result directly from obeying super-Jacobi identities. We point out particular requirements that superalgebras have to satisfy to be successfully incorporated within valid supergravity actions. The presented algebraic and Lagrangian framework organizes and helps us better understand relations between the various supergravity and supersymmetric Chern-Simons actions invariant under diverse resonant superalgebras.

As redes que conformam a cadeia de produção agroexportadora da carne bovina mostram alta performance, sendo responsáveis por tornar o Brasil o maior exportador do produto no mercado global. Os resultados deste estudo de caso indicam que a vulnerabilidade de apenas um nó da rede pode ser responsável pelo comprometimento da performance de toda a rede. Isto é reforçado pela configuração da rede estudada: uma rede rotinizada, com baixo grau de influência da empresa focal. A partir da noção de organização de alta-confiabilidade, um quadro de referência é desenvolvido e discutido, buscando assim ajudar os tomadores de decisão na formulação de estratégias de redesenho da rede.

description: Serious games are games that contribute to a purpose other than pure entertainment. The serious games industry and research community are growing rapidly. However, research on their effectiveness has long been based on theoretical assumptions about their potential, but has been missing empirical evidence. Studies attempting to evaluate serious games show inconclusive, inconsistent and even contradictory results. This is caused by a lack of standardized methods and guidelines to avoid common mistakes in the evaluation of serious games, and the unquestioned adoption of methodologies from other domains. This thesis attempts to identify issues in common methodologies used in the evaluation of serious games. This includes the identification of mediating variables as well as some peculiarities regarding the evaluation of games. The use of randomized controlled trials - promoted as method of choice in the field - is found to be unnecessary or even inappropriate in many cases. The common use of media comparison designs is discouraged, primarily due to their assumption that instructions in different media can be designed to teach identical content, and therefore the impact of the instructional medium can be isolated and measured. Many evaluations of serious games make assumptions based on misconceptions about games. To develop a common understanding of the domain, a unified perspective is proposed to aid design, application, evaluation and iteration of serious games. The prerequisites for it, namely the understanding of game dynamics, of learning theories and of their possible applications in games, are covered in this work. The proposed new perspective on the design and evaluation of serious games is exemplified on the games EnerCities, Spent, and Portal 2. All of them have been evaluated in instructional contexts in previous studies. In this work, the games are analyzed from a learning theoretical standpoint to explain evaluation results from previous studies.

description: Microexpressions are fast and spatially small facial expressions that are difficult to detect. Therefore motion magnification techniques, which aim at amplifying and hence revealing subtle motion in videos, appear useful for handling such expressions. There are basically two main approaches, namely via Eulerian or Lagrangian techniques. While the first one magnifies motion implicitly by operating directly on image pixels, the Lagrangian approach uses optical flow (OF) techniques to extract and magnify pixel trajectories. In this paper, we propose a novel approach for local Lagrangian motion magnification of facial micro-motions. Our contribution is three-fold: first, we fine tune the recurrent all-pairs field transforms (RAFT) for OFs deep learning approach for faces by adding ground truth obtained from the variational dense inverse search (DIS) for OF algorithm applied to the CASME II video set of facial micro expressions. This enables us to produce OFs of facial videos in an efficient and sufficiently accurate way. Second, since facial micro-motions are both local in space and time, we propose to approximate the OF field by sparse components both in space and time leading to a double sparse decomposition. Third, we use this decomposition to magnify micro-motions in specific areas of the face, where we introduce a new forward warping strategy using a triangular splitting of the image grid and barycentric interpolation of the RGB vectors at the corners of the transformed triangles. We demonstrate the feasibility of our approach by various examples.

description: We re-explore the symmetries of a weakly isolated horizon (WIH) from the perspective of freedom in the choice of intrinsic data. The supertranslations are realized as additional symmetries. Further, it is shown that all smooth vector fields tangent to the cross-sections are Hamiltonian. We show that joining two WIHs which differ in these Hamiltonians and boundary data, under the action of a supertranslation, necessarily require the inclusion of an intermediate dynamical phase, possibly with the inclusion of a stress energy tensor. This phase of the boundary is non-expanding but not a WIH and invariably leads to a violation of the dominant energy condition. The assumptions made allow us to reconstruct the (classically) pathological stress energy tensor also.

Dicho precio solo resulta competitivo si en la evaluacion se considera el beneficio ambiental de la retirada de nutrientes, imputado mediante el principio de los costes evitados...During the last decades, the Mar Menor coastal lagoon (SE Spain) is suffering an eutrophication and degradation process of its water quality, partly due to the load of nutrients coming from agricultural drainage of the watershed. This work presents an economic assessment of two management options: i) a desalination plant to treat and reuse the agricultural drainage water and ii) the recovery of a wetland to retain and remove the nutrients. The cost-effectiveness analysis shows the advantages of his latter option. Then it is estimated, under different hypothesis, the water price required to copley with the principle of full cost recovery of the Water Framework Directive (WFD). This water price is competitive only if the assessment takes into account the environmental benefits of the nutrients removal, which are calculated using the avoided costs principle.

description: We present measurements of cross-sections for production of a leptonically decaying $Z$ boson in association with a large-radius jet in 13 TeV proton-proton collisions at the LHC, using $36~\mathrm{fb}^{-1}$ of data from the ATLAS detector. Integrated and differential cross-sections are measured at particle-level in both a flavor-inclusive and a doubly $b$-tagged fiducial phase-space. The large-radius jet mass and transverse momentum, its kinematic relationship to the $Z$ boson, and the angular separation of $b$-tagged small-radius track-jets within the large-radius jet are measured. This measurement constitutes an important test of perturbative quantum chromodynamics in kinematic and flavor configurations relevant to several Higgs boson and beyond-Standard-Model physics analyses. The results highlight issues with modeling of additional hadronic activity in the flavor-inclusive selection, and a distinction between flavor-number schemes in the $b$-tagged phase-space.

Por otro lado, se propne y emplea una metodologia para analizar los contenidos del sitio web. Se ha analizado la presencia en Internet de 306 empresas hortofruticolas espanolas de tamano mediano, encontrando que un 10,1 por ciento todavia no cuentan con un sitio web ajeno, es decir, se trata simplemente de directorios mantenidos por terceros con informacion estandar de cada empresa. Solo un 22,5 por ciento poseen un sitio web propio. Su analisis revela que son sitios sencillos, siendo su proposito fundamental el ofrecer informacion de la empresa. Aun asi, los resultados del Analisis de la Varianza demuestran que contrar con un sitio web, mas aun si es propio, es una caracteristica diferencial de las empresas mas productivas...The aim of this study is twofold. On the one hand, it analyzes website adoption in horticulture and fruit Spanish businesses as well as its relation with firm performance. On the other hand, a methodology to evaluate web content is proposed and used. The web presence of 306 medium-sized horticulture and fruit Spanish business was analyzed. Findings showed that 10.1 percent of the firms still do not have a website. The majority of the businesses, 67.3 percent, have websites owned by a third-party, that is, web directories hosted and managed by a third-party with merely standard information of the companies. Only 22.5 percent of firms have privately-owned websites. Web content analysis revealed that these are simple websites, being the offering of corporate information their main purpose. However, results from analysis of variance confirmed that having a website, preferable privately-owned, is a differentiating feature of most productive firms.

description: We present a thorough inspection of the dynamical behavior of epidemic phenomena in populations with complex and heterogeneous connectivity patterns. We show that the growth of the epidemic prevalence is virtually instantaneous in all networks characterized by diverging degree fluctuations, independently of the structure of the connectivity correlation functions characterizing the population network. By means of analytical and numerical results, we show that the outbreak time evolution follows a precise hierarchical dynamics. Once reached the most highly connected hubs, the infection pervades the network in a progressive cascade across smaller degree classes. Finally, we show the influence of the initial conditions and the relevance of statistical results in single case studies concerning heterogeneous networks. The emerging theoretical framework appears of general interest in view of the recently observed abundance of natural networks with complex topological features and might provide useful insights for the development of adaptive strategies aimed at epidemic containment.

description: El objectivo de este trabajo consiste en desarrollar una metodologia util que facilite a productores y almacienistas de las variedades tradicionales de manzana del Alto Valle de Rio Negro y Neuquen la toma de decisiones de comercializacion en un contecto de creciente incertidumbre sobre la evolucion de los precios. para ello, se analizan los costes de conservacion a lo largo de la campana y se comparan con los ingresos reales obtenidos y con los que se obtendrian a partir de rediccones de precios realizadas con modelos de series temporales son capaces de generar predicciones comparables en precision a las generadas por los agentes que trabajan en el sector, si bien estas ultimas son mejores conforme aumenta el horizonte de la prediccion. Finalmente, las decisiones que adoptan los productores en base a sus expectativas son similares a las que se hubiesen obtenido con los precios predichos, sugiriendo concentrar las ventas en los ultimos meses del ano...The aim of this paper is to provide a methodological framework to facilitate farmers and warehouses managers the adoption of marketing strategies, in an environment of increasing uncertainty about price evolution. In this paper we make a rigorous analysis of conservation costs along the marketing season and we compare them with revenues calculated using both real and forecasted prices. Results suggest a similar forecasting performance of time series models against experts forecasts, although the latter are better as the forecasting horizon lengthens. Time series forecasts also provide good results in terms of marketing margins and suggest concentrating sales in the last part of the marketing season just when market prices are higher. This is consistent with actual warehouses common practice.

description: In the intersection of the theories of nonsymmetric Jack polynomials in $N$ variables and representations of the symmetric groups $\mathcal{S}_{N}$ one finds the singular polynomials. For certain values of the parameter $κ$ there are Jack polynomials which span an irreducible $\mathcal{S}_{N}$-module and are annihilated by the Dunkl operators. The $\mathcal{S}_{N}$-module is labeled by a partition of $N$, called the isotype of the polynomials. In this paper the Jack polynomials are of the vector-valued type, that is, elements of the tensor product of the scalar polynomials with the span of reverse standard Young tableaux of the shape of a fixed partition of $N$. In particular this partition is of shape $\left( m,m,\ldots,m\right) $ with $2k$ components and the constructed singular polynomials are of isotype $\left( mk,mk\right) $ for the parameter $κ=$ $1/\left( m+2\right) $. The paper contains the necessary background on nonsymmetric Jack polynomials and representation theory and explains the role of Jucys-Murphy elements in the construction. The main ingredient is the proof of uniqueness of certain spectral vectors, namely, the list of eigenvalues of the Jack polynomials for the Cherednik-Dunkl operators, when specialized to $κ=1/\left( m+2\right) $. The paper finishes with a discussion of associated maps of modules of the rational Cherednik algebra and an example illustrating the difficulty of finding singular polynomials for arbitrary partitions.

The methodology starts with a meticulous study of the production process, from which a costing system for certain varieties of pears and apples is designed, by considering the model of plant conduction and the size of the fruit farms. In this research, there are some tools to take critic decisions using the Cost-Volunme-Utility analysis and models of simulation. To conclude, a Balance Scorecard is designed with the purpose of controlling the key variables of the business, not only the tangible but also the intangible ones, from a perspective of strategic and integral management. From this research, it is demonstrated the crisis that fruit growing farms are going over nowadays.

description: To any $n \times n$ Latin square $L$, we may associate a unique sequence of mutually orthogonal permutation matrices $P = P_1, P_2, ..., P_n$ such that $L = L(P) = \sum kP_k$. Brualdi and Dahl (2018) described a generalisation of a Latin square, called an alternating sign hypermatrix Latin-like square (ASHL), by replacing $P$ with an alternating sign hypermatrix (ASHM). An ASHM is an $n \times n \times n$ (0,1,-1)-hypermatrix in which the non-zero elements in each row, column, and vertical line alternate in sign, beginning and ending with $1$. Since every sequence of $n$ mutually orthogonal permutation matrices forms the planes of a unique $n \times n \times n$ ASHM, this generalisation of Latin squares follows very naturally, with an ASHM $A$ having corresponding ASHL $L = L(A) =\sum kA_k$, where $A_k$ is the $k^{\text{th}}$ plane of $A$. This paper addresses some open problems posed in Brualdi and Dahl's article, firstly by characterising how pairs of ASHMs with the same corresponding ASHL relate to one another and providing a tight lower bound on $n$ for which two $n \times n \times n$ ASHMs can correspond to the same ASHL, and secondly by exploring the maximum number of times a particular integer may occur as an entry of an $n \times n$ ASHL. A general construction is given for an $n \times n$ ASHL with the same entry occurring $\lfloor\frac{n^2 + 4n -19}{2}\rfloor$ times, improving considerably on the previous best construction, which achieved the same entry occuring $2n$ times.

description: We consider black hole solutions with a dilaton field possessing a nontrivial potential approaching a constant negative value at infinity. The asymptotic behaviour of the dilaton field is assumed to be slower than that of a localized distribution of matter. A nonabelian SU(2) gauge field is also included in the total action. The mass of the solutions admitting a power series expansion in $1/r$ at infinity and preserving the asymptotic anti-de Sitter geometry is computed by using a counterterm subtraction method. Numerical arguments are presented for the existence of hairy black hole solutions for a dilaton potential of the form $V(ϕ)=C_1 \exp(2α_1 ϕ)+C_2 \exp(2α_2 ϕ)+C_3$, special attention being paid to the case of ${\cal N}=4, D=4$ gauged supergravity model of Gates and Zwiebach.
