The influence of product creativity on competitive advantage

This research aimed to explore and analyse the influence of product creativity on competitive advantages in Micro, Small, or Medium Enterprises (MSMEs) within the ceramic centres in Plered Purwakarta. Given that competition in ceramic MSMEs has been becoming steadily more challenging, this research speaks to a practical challenge that must be addressed for their continued survival within this region. The method used in this study is descriptive verificative and is accomplished through regression and correlation analysis techniques. The sample in this study is 65 respondents. The study's descriptive analysis results found that of the total population of ceramic workers in the sample, 65.9% of them were sufficiently creative. When analysing the subconstructs of creativity used in this study, "product novelty" indicators were the highest, with the lowest indicator being "product transformation". The variable value of competitive advantage total score of 63.4% indicates that the target population is quite competitive regarding "price advantage" indicators. However, they scored low on general competition level indicators.
Geometric properties of reliability polynomials

Geometric modeling of multivariate reliability polynomials is based on algebraic hypersurfaces, constant level sets, rulings etc. The solved basic problems are: (i) find the reliability polynomial using the Maple and Matlab software environment; (ii) find restrictions of reliability polynomial via equi-reliable components; (iii) how should the reliability components linearly depend on time, so that the reliability of the system be linear in time? The main goal of the paper is to find geometric methods for analysing the reliability of electric systems used inside aircrafts.
Regularity and uniqueness for a class of solutions to the hydrodynamic flow of nematic liquid crystals

In this paper, we establish an $\epsilon$-regularity criterion for any weak solution $(u,d)$ to the nematic liquid crystal flow (1.1) such that $(u,\nabla d)\in L^p_tL^q_x$ for some $p\ge 2$ and $q\ge n$ satisfying the condition (1.2). As consequences, we prove the interior smoothness of any such a solution when $p>2$ and $q>n$. We also show that uniqueness holds for the class of weak solutions $(u,d)$ the Cauchy problem of the nematic liquid crystal flow (1.1) that satisfy $(u,\nabla d)\in L^p_tL^q_x$ for some $p>2$ and $q>n$ satisfying (1.2).
Cross Field-Based Segmentation and Learning-Based Vectorization for Rectangular Windows

Detection and vectorization of windows from building façades are important for building energy modeling, civil engineering, and architecture design. However, current applications still face the challenges of low accuracy and lack of automation. In this article we propose a new two-steps workflow for window segmentation and vectorization from façade images. First, we propose a cross field learning-based neural network architecture, which is augmented by a grid-based self-attention module for window segmentation from rectified façade images, resulting in pixel-wise window blobs. Second, we propose a regression neural network augmented by squeeze-and-excitation (SE) attention blocks for window vectorization. The network takes the segmentation results together with the original façade image as input, and directly outputs the position of window corners, resulting in vectorized window objects with improved accuracy. In order to validate the effectiveness of our method, experiments are carried out on four public façades image datasets, with results usually yielding a higher accuracy for the final window prediction in comparison to baseline methods on four datasets in terms of intersection over union score, F1 score, and pixel accuracy.
Essential Fatty Acid Deficiency in Cystic Fibrosis Disease Progression: Role of Genotype and Sex

Adequate intake of nutrients such as essential fatty acids (EFA) are critical in cystic fibrosis (CF). The clinical course of deterioration of lung function in people with CF has been shown to relate to nutrition. Independent of the higher energy consumption and malabsorption due to pancreatic insufficiency, EFA deficiency is closely associated with the risk of pulmonary infection, the most significant pathology in CF. This review will focus on the EFA deficiency identified in people with CF, as well as the limited progress made in deciphering the exact metabolic pathways that are dysfunctional in CF. Specifically, people with CF are deficient in linoleic acid, an omega 6 fatty acid, and the ratio of arachidonic acid (omega 6 metabolite) and docosahexaenoic acid (omega 3 metabolite) is increased. Analysis of the molecular pathways in bronchial cells has identified changes in the enzymes that metabolise EFA. However, fatty acid metabolism primarily occurs in the liver, with EFA metabolism in CF liver not yet investigated, indicating that further research is required. Despite limited understanding in this area, it is well known that adequate EFA concentrations are critical to normal membrane structure and function, and thus are important to consider in disease processes. Novel insights into the relationship between CF genotype and EFA phenotype will be discussed, in addition to sex differences in EFA concentrations in people with CF. Collectively, investigating the specific effects of genotype and sex on fatty acid metabolism may provide support for the management of people with CF via personalised genotype- and sex-specific nutritional therapies.
2D Homogeneous Solutions to the Euler Equation

In this paper we study classification of homogeneous solutions to the stationary Euler equation with locally finite energy. Written in the form u = ∇⊥Ψ, Ψ(r, θ) = r λψ(θ), for λ > 0, we show that only trivial solutions exist in the range 0 < λ <1/2, i.e. parallel shear and rotational flows. In other cases many new solutions are exhibited that have hyperbolic, parabolic and elliptic structure of streamlines. In particular, for λ > 9/2 the number of different non-trivial elliptic solutions is equal to the cardinality of the set . The case λ = 2/3 is relevant to Onsager's conjecture. We underline the reasons why no anomalous dissipation of energy occurs for such solutions despite their critical Besov regularity 1/3.
Exploring the Impact of Localized COVID-19 Events on Intercity Mobility during the Normalized Prevention and Control Period in China

Uncontrolled, large-scale human mobility can amplify a localized disease into a pandemic. Tracking changes in human travel behavior, exploring the relationship between epidemic events and intercity travel generation and attraction under policies will contribute to epidemic prevention efforts, as well as deepen understanding of the essential changes of intercity interactions in the post-epidemic era. To explore the dynamic impact of small-scale localized epidemic events and related policies on intercity travel, a spatial lag model and improved gravity models are developed by using intercity travel data. Taking the localized COVID-19 epidemic in Xi’an, China as an example, the study constructs the travel interaction characterization before or after the pandemic as well as under constraints of regular epidemic prevention policies, whereby significant impacts of epidemic events are explored. Moreover, indexes of the quantified policies are refined to the city level in China to analyze their effects on travel volumes. We highlight the non-negligible impacts of city events and related policies on intercity interaction, which can serve as a reference for travel management in case of such severe events.
Inverse scattering problem for Sturm-Liouville operator on non-compact A-graph. Uniqueness result.

We consider a connected metric graph with the following property: each two cycles can have at most one common point. Such graphs are called A-graphs. On noncompact A-graph we consider a scattering problem for Sturm-Liouville differential operator with standard matching conditions in the internal vertices. Transport, spectral and scattering problems for differential operators on graphs appear frequently in mathematics, natural sciences and engineering. In particular, direct and inverse problems for such operators are used to construct and study models in mechanics, nano-electronics, quantum computing and waveguides. The most complete results on (both direct and inverse) spectral problems were achieved in the case of Sturm-Liouville operators on compact graphs, in the noncompact case there are no similar general results. In this paper, we establish some properties of the spectral characteristics and investigate the inverse problem of recovering the operator from the scattering data. A uniqueness theorem for such inverse problem is proved.
Sequential Multidimensional Spectral Estimation

By considering an empirical approximation, and a new class of operators that we will call walking operators, we construct, for any positive ND-toeplitz matrix, an infinite in all dimensions matrix, for which the inverse approximates the original matrix in its finite part. A recursive hierarchical algorithm is presented for sequential dimension spectral representation. A positive comparison in calculus cost, and numerical simulation, for 2D and 3D signals, is also presented.
On a weak Jelonek's real Jacobian Conjecture in $\R^n$

Let $Y:\R^n\to\R^n$ be a polynomial local diffeomorphism and let $S_Y$ denote the set of not proper points of $Y$. The Jelonek's real Jacobian Conjecture states that if $\codim(S_Y)\geq2$, then $Y$ is bijective. We prove a weak version of such conjecture establishing the sufficiency of a necessary condition for bijectivity. Furthermore, we generalize our result on bijectivity to semialgebraic local diffeomorphisms.
The embodied musicality of hetero-cisgender violence: an analysis strategy to study mental health problems from a narrative-dialogic perspective

ABSTRACT This paper proposes a narrative-dialogic analysis strategy to study the relationship between gender/sex identity and mental health problems in the context of heteronormativity. This strategy is called listening to the embodied musicality of hetero-cisgender violence. Inspired by a narrative-dialogic theory of gender/sex identity development and applying methodological tools from dialogic and language-based mental health research, a novel strategy to analyze the relationship between gender/sex identity and mental health is developed. Data from a study conducted in Santiago de Chile with non-heterosexual masculinities is drawn on to exemplify this method. The analysis strategy has the capacity to study narrative meaning-making practices without reproducing traditional divides within the social sciences, such as the mind body split. The codes developed through the analysis strategy address the relationship between gender/sex identity and mental health, by highlighting the embodied emotional effects that hetero-cisgender violence and resistance against it have on narrative meaning-making practices. The analysis strategy presents a novel approach that addresses the embodied emotional texture of self-narratives, as opposed to more traditional dimensions commonly used in the study of the mental health of non-heterosexual people.
Dual Negativity of CD56 and CD117 Links to Unfavorable Cytogenetic Abnormalities and Predicts Poor Prognosis in Multiple Myeloma

The prognostic value of CD56 and CD117 expression on myeloma cells is controversial. This study aims to analyze the correlation of CD56 and CD117 expression with cytogenetic abnormalities and survival. A total of 128 patients with newly diagnosed multiple myeloma (NDMM) were recruited in this single-center retrospective study. Flow cytometry and FISH tests of marrow cells were performed for all of the subjects. The statistical methods included a chi-squared test, univariate and multivariate COX regressions, and a Kaplan-Meier survival curve analysis. Regarding the cytogenetics, the incidence of IgH/FGFR3 translocation was more frequent in patients with a negative CD56 (p = 0.003). CD56 negativity was an independent adverse factor associated with a poor prognosis (p = 0.019) and indicated a shorter overall survival (OS) (p = 0.021). Patients with dual negative CD56 and CD117 trended toward a poorer OS (CD56−CD117− vs. CD56+CD117−, p = 0.011; CD56−CD117− vs. CD56+CD117+, p = 0.013). In conclusion, CD56 is a prognostic marker that independently affects OS and is associated with adverse cytogenetic abnormalities. Patients with a dual negativity of CD56 and CD117 have a worse clinical outcome.
A new approach to the analysis of the phase space of f(R)-gravity

We propose a new dynamical system formalism for the analysis of f(R) cosmologies. The new approach eliminates the need for cumbersome inversions to close the dynamical system and allows the analysis of the phase space of f(R)-gravity models which cannot be investigated using the standard technique. Differently form previously proposed similar techniques, the new method is constructed in such a way to associate to the fixed points scale factors, which contain four integration constants (i.e. solutions of fourth order differential equations). In this way a new light is shed on the physical meaning of the fixed points. We apply this technique to some f(R) Lagrangians relevant for inflationary and dark energy models.
Rigidity and height bounds for certain post-critically finite endomorphisms of projective space

The holomorphic endomorphism f of projective space is called post-critically finite (PCF) if the forward image of the critical locus, under iteration of f, has algebraic support (i.e., is a finite union of hypersurfaces). In the case of dimension 1, a deep result of Thurston implies that there are no algebraic families of PCF morphisms, other than a well-understood exceptional class known as the flexible Lattes maps. This note proves a corresponding result in arbitrary dimension, for a certain subclass of morphism. Specifically, we restrict attention to morphisms f of degree at least two, with a totally invariant hyperplane H, such that the restriction of f to H is the dth power map in some coordinates. This condition defines a subvariety of the space of coordinate-free endomorphisms of projective space (of a given dimension). We prove that there are no families of PCF maps in this space, and derive several related arithmetic results.
FOCAL RIGIDITY OF HYPERBOLIC SURFACES

In this note, we consider the rigidity of the focal decomposition of closed hyperbolic surfaces. We show that, generically, the focal decomposition of a closed hyperbolic surface does not allow for non-trivial topological deformations, without changing the hyperbolic structure of the surface. By classical rigidity theory this is also true in dimension n ‚ 3. Our current result extends a previous result that flat tori in dimension n ‚ 2 that are focally equivalent are isometric modulo rescaling. 1. Definitions and statement of results The purpose of this note is to consider the rigidity of the focal decomposition of closed hyperbolic surfaces. In order to state the precise result, we first recall the notion of focal decomposition and focal equivalence for general manifolds. Let (M;g) be a closed, i.e., compact and boundaryless, and analytic (C ! ) Riemannian n-manifold. A closed hyperbolic surface is naturally a closed analytic manifold in this sense. Fix a closed analytic manifold (M;g). Definition 1. The focal index, I(p;v), of the vector v 2 TpM is defined by I(p;v) = # ' w 2 TpM j jvj = jwj and exp p (v) = exp p (w) " :
The Covariance of Almost-Primes in q[T]

We estimate the covariance in counts of almost-primes in $\mathbb{F}_q[T]$, weighted by higher-order von Mangoldt functions. The answer takes a pleasant algebraic form. This generalizes recent work of Keating and Rudnick that estimates the variance of primes, and makes use, as theirs, of a recent equidistribution result of Katz. In an appendix we prove some related identities for random matrix statistics, which allows us to give a quick proof of a $2\times2$ ratio theorem for the characteristic polynomial of the unitary group. We additionally identify arithmetic functions whose statistics mimic those of hook Schur functions.
Existence and symmetric result for Liouville-Weyl fractional nonlinear Schr\"odinger equation

We study the existence of positive solution for the one dimensional Schr\"odinger equation with mixed Lioville-Weyl fractional derivatives \begin{eqnarray*}\label{Eq00} _{t}D_{\infty}^{\alpha}({_{-\infty}}D_{t}^{\alpha}u(t)) + V(t) u(t) = & f(u(t)),\;\;t\in \mathbb{R}\\ u\in H^{\alpha}(\mathbb{R}). \nonumber \end{eqnarray*} Furthermore, we analyse radial symmetry property of these solutions. The proof is carried out by using variational methods jointly with comparison and rearrangement argument.
Anorexia in Adolescents: A Narrative Review

The prevalence of anorexia nervosa has ranged from 27% in non-clinical samples to 85% in samples of adolescents with eating disorders, with twice the prevalence noted in females. Several correlates of anorexia are reported in the recent literature reviewed here including vegetarian diets, personality characteristics such as internalizing and perfectionism as well as behavior problems including impulsivity, dysregulation and being victimized. Comorbidities have included social anxiety, depression and suicidal ideation. In most of these studies, it is not clear which is the primary disorder, as most of the samples are cross-sectional rather than longitudinal. Several of the correlates have also been identified as risk factors including gender, early attachment disturbances, excessive Internet use and negative effects of COVID-19. Potential underlying mechanisms have included involvement of the prefrontal area of the brain based on fMRI and evoked potential research. Fortunately, negative effects of anorexia including decreased body fat mass and bone density as well as lower cortical thickness and less grey matter have been reversed following weight gain. Other effective interventions have included cognitive behavior and dialectical behavior therapy. This narrative review involved entering the terms eating disorders and adolescents into PubMed and PsycINFO. The search yielded 251 papers for the last five years, but following exclusion criteria including case studies and non-English papers, this review is a summary of the research reported in 49 papers. The recent literature on eating disorders in adolescents is predominantly focused on correlates and risk factors for anorexia along with some studies on comorbidities and potential underlying mechanisms for anorexia. Although there are virtually no studies on the effects of anorexia except its effects on body mass and bone mineral density, several intervention studies appear in this literature. Related studies are focused on orthorexia. This narrative review is accordingly divided into sections on the prevalence of anorexia, comorbidities, correlates, risk factors, potential underlying mechanisms and interventions. In a separate section, the smaller literature on orthorexia and drunkorexia is briefly reviewed.
The New Precarization of Work: a Conceptual Map

Abstract The new precarization of work, flexible precarization, presents changes and significant new elements within the context of precarious work. As a historical manifestation, it has gradually been included within structural-economic and institutional-political reforms. This paper aims to propose a conceptual map of the new precarization of work. The conceptual map is a critical tool for developing a scientific investigation and links concepts, context, and theoretical influences to promote the advancement of research in the field of the object studied. Three dimensions embodied the proposed map: the context, synthesized in the rise of neoliberalism, in the hegemony of the financial sector, in productive restructuring, and in economic globalization; flexible practices, in the condition of manifestations and causalities of the social arrangements, exposed in terms of the naturalization of unemployment, economic fatalism, the emptying of the State, the sanctity of contracts, deregulation, work intensification, the capture of savoir faire , decentralization and deterritorialization of productive units, technocratic manipulations, the weakening of the unions, part-time or temporary work, outsourcing, and despecialization; and the categories, relational expressions identified as flexible capitalism, flexible business, flexibility (flexible regulation), social precarization, and the movement from formal to real subsumption. Providing a synthesized image that seeks to critically apprehend the concreteness of the real, the map can be used as a script for new research and to contribute to critiques in the field of organizational studies.
Monitoring Spatially Heterogeneous Dynamics in a Drying Colloidal Thin Film

We report on a new type of experiment that enables us to monitor spatially and temporally heterogeneous dynamic properties in complex fluids. Our approach is based on the analysis of near-field speckles produced by light diffusely reflected from the superficial volume of a strongly scattering medium. By periodic modulation of an incident speckle beam we obtain pixel-wise ensemble averages of the structure function coefficient, a measure of the dynamic activity. To illustrate the application of our approach we follow the different stages in the drying process of a colloidal thin film. We show that we can access ensemble averaged dynamic properties on length scales as small as ten micrometers over the full field of view.
A unifying energy-based approach to optimal frequency and market regulation in power grids

In this paper we provide a unifying energy-based approach to the modeling, analysis and control of power systems and markets, which is based on the port-Hamiltonian framework. Using a primal-dual gradient method applied to the social welfare problem, a distributed dynamic pricing algorithm in port-Hamiltonian form is obtained. By interconnection with the physical model a closed-loop port-Hamiltonian system is obtained, whose properties are exploited to prove asymptotic stability to the optimal points. This result is extended such that also general nodal power constraints are included into the social welfare problem. Additionally, the cases of line congestion and power transmission cost in (a)cyclic networks considering (non)linear power flow models are covered as well. Finally, we provide port-Hamiltonian descriptions and analysis of the well studied distributed averaging proportional integral (DAPI) and certain internal-model-based controllers, which solve an optimal frequency regulation problem.
Discontinuous Galerkin methods for the p-biharmonic equation from a discrete variational perspective

We study discontinuous Galerkin approximations of the p-biharmonic equation for p 2 (1;1) from a variational perspective. We propose a discrete variation al formulation of the problem based on an appropriate definition of a finite element Hessian and study convergence of the method (without rates) using a semicontinuity argument. We also present numerical experiments aimed at testing the robustness of the method.
