Development of Application Providing Public’s Perspectives on Official Statistical Indicators

BPS-Statistics Indonesia, as an official data producer, puts data quality as a top priority. Public acceptance and trust in data reflect data reliability which is one of the data quality indicators. The existing survey that collects user acceptance, trust, and perspective to data produced by BPS can only reach data users in a limited number. Perspectives from a large number of data users cannot be captured. This research aims to build an application that collects and provides users’ perspectives and sentiment to official statistics sourced from online news. One feature in this application is Named Entity Recognition, which extracts public perspectives in entities such as names, organizations, statistical indicators, quotes or opinions, etc. This application objectively measures the sentiment of news discussing or citing statistical indicators. This application also facilitates BPS to do social network analysis to understand the relationships between fellow data users for each statistical indicator. The implicit goal is to effectively provide insights into how frequently society uses and refers to statistical indicators produced by BPS in any domain and their perspective on data. All models and features provided in this application have been evaluated based on standard performance metrics.
Self-similarity detection in random texture via multi-scale image analysis

A dynamic scheme is presented for generating a multi-scale image associated with self-similar patterns. By blurring with small scale parameters, zero cross boundaries are extended to geometrically singular fractal patterns. Through weighted averaging with respect to scale factors, a version of conditional probability is well defined to evaluate the chasing process for unknown attractors. The imaging process, thus, is identified via the minimization of missing risk. The proposed method is verified by simulation studies.

The claimed antenna is applicable for various wireless applications.
Big Cohen-Macaulay Modules, Morphisms of Perfect Complexes, and Intersection Theorems in Local Algebra

There is a well known link from the first topic in the title to the third one. In this paper we thread that link through the second topic. The central result is a criterion for the tensor nilpotence of morphisms of perfect complexes over commutative noetherian rings, in terms of a numerical invariant of the complexes known as their level. Applications to local rings include a strengthening of the Improved New Intersection Theorem, short direct proofs of several results equivalent to it, and lower bounds on the ranks of the modules in every finite free complex that admits a structure of differential graded module over the Koszul complex on some system of parameters.
Generalized Morrey Regularity for Parabolic Equations with Discontinuous Data

Abstract We prove continuity in generalized parabolic Morrey spaces of sublinear operators generated by the parabolic Calderón—Zygmund operator and by the commutator of this operator with bounded mean oscillation (BMO) functions. As a consequence, we obtain a global -regularity result for the Cauchy—Dirichlet problem for linear uniformly parabolic equations with vanishing mean oscillation (VMO) coefficients.
Ricci‐flat deformations of metrics with exceptional holonomy

Let G be one of the Ricci‐flat holonomy groups SU(n), Sp(n), Spin(7) or G2, and M a compact manifold of dimension 2n, 4n, 8 or 7, respectively. We prove that the natural map from the moduli space of torsion‐free G‐structures on M to the moduli space of Ricci‐flat metrics is open, and that the image is a smooth manifold. For the exceptional cases G = Spin(7) and G2, we extend the result to asymptotically cylindrical manifolds.
A Distributed ADMM-like Method for Resource Sharing over Time-Varying Networks

We consider cooperative multi-agent resource sharing problems over time-varying communication networks, where only local communications are allowed. The objective is to minimize the sum of agent-specific composite convex functions subject to a conic constraint that couples agents' decisions. We propose a distributed primal-dual algorithm DPDA-D to solve the saddle point formulation of the sharing problem on time-varying (un)directed communication networks; and we show that primal-dual iterate sequence converges to a point defined by a primal optimal solution and a consensual dual price for the coupling constraint. Furthermore, we provide convergence rates for suboptimality, infeasibility and consensus violation of agents' dual price assessments; examine the effect of underlying network topology on the convergence rates of the proposed decentralized algorithm; and compare DPDA-D with a centralized method on the basis pursuit denoising and multi-channel power allocation problems.
Investigation of hub genes and immune infiltration in androgenetic alopecia using bioinformatics analysis

Background Androgenetic alopecia (AGA) is a type of non-scarring hair loss. Current drugs for AGA are accompanied by adverse reactions and a high recurrence rate. Thus, the discovery of diagnostic biomarkers and therapeutic targets for AGA remains imperatively warranted. Methods The GSE90594 dataset, which contained scalp skin biopsies from 14 male AGA cases and healthy volunteers, was used to identify the differentially expressed genes (DEGs). Functional enrichment analysis was subsequently performed. Next, the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database combined with the cytoHubba plugin of Cytoscape were used to obtain the key genes of AGA. Thereafter, the Cell-type Identification by Estimating Relative Subsets of RNA Transcripts (CIBERSORT) algorithm was performed to evaluate the relative abundance of immune cells between male AGA patients and healthy controls. The correlation between key genes and infiltrating immune cells was analyzed to obtain the significant immune-cell related genes (IRGs), then intersected with the DEGs between immortalized balding and non-balding human dermal papilla cells (DPCs) of the GSE93766 dataset as well as the DEGs obtained by the GSE90594 dataset, thus obtaining the hub genes of AGA. Finally, the hub genes were validated using GSE36169, which contained expression profiling of tissues biopsied from haired and bald scalps of five individuals with AGA. Results A total of 234 DEGs were obtained from the GSE90594 dataset, which were mainly enriched in the extracellular matrix (ECM)-related pathways and immune-related activities. The STRING database and ten algorithms in the cytoHubba plugin of Cytoscape disclosed 21 key DEGs. The results of the CIBERSORT algorithm revealed the relative abundances of 20 kinds of immune cells between diseased and healthy individuals, and yielded 15 IRGs involved in the pathogenesis of AGA. Next, the intersection analysis identified four hub genes of AGA, comprising COL1A2, PCOLCE, ITGAX, and LOX. The GSE36169 dataset validated the expression pattern of hub genes in the haired scalp of AGA patients. Conclusions We discovered that the hub genes identified are closely linked with the causative factors of AGA, which could be used as the viable diagnostic and therapeutic target in the clinical applications.
Local and Regional Components of Sensible Heat Advection

Abstract Detailed knowledge of the advection of sensible heat is necessary to understand the energy balance of the evaporating surface in many parts of the world. Sensible heat advection can result from regional and/or local sources. The local and regional components of sensible heat advection (Aloc and Areg, respectively) are identified and their magnitudes in a semi-arid to sub-humid zone are established in the work reported here. Measurements of dry- and wet-bulb air temperature, wind speed and net radiation were made above an irrigated alfalfa field with relatively dry surroundings upwind at Mead, NE. A modified Bowen ratio-energy balance method which incorporates horizontal gradients of air temperature and vapor pressure was used to compute evapotranspiration (ET) rates. Sensible heat advection at the furthest upwind location in the irrigated field contributed from 15 to 50% of the energy consumed in ET on a daily basis. Areg was greatest on days with strong winds; Aloc was independent of wind speed.
Morphisms of generalized interval systems and PR-groups

We begin the development of a categorical perspective on the theory of generalized interval systems (GISs). Morphisms of GISs allow the analyst to move between multiple interval systems and connect transformational networks. We expand the analytical reach of the Sub Dual Group Theorem of Fiore and Noll [Commuting groups and the topos of triads. In: Agon C, Amiot E, Andreatta M, Assayag G, Bresson J, Mandereau J, editors. Proceedings of the 3rd International Conference Mathematics and Computation in Music - MCM 2011. Lecture Notes in Computer Science, Springer; 2011] and the generalized contextual group of Fiore and Satyendra [Generalized contextual groups. Music Theory Online. 2005;11] by combining them with a theory of GIS morphisms. Concrete examples include an analysis of Schoenberg, String Quartet in D minor, op. 7, and simply transitive covers of the octatonic set. This work also lays the foundation for a transformational study of Lawvere–Tierney upgrades in the topos of triads of Noll [The topos of triads. In: Colloquium on mathematical music theory. Graz: Karl-Franzens-Univ. Graz; 2005. p. 103–135].
Thermal derivation of the Coleman-De Luccia tunneling prescription

We derive the rate for transitions between de Sitter vacua by treating the field theory on the static patch as a thermal system. This reproduces the Coleman-De Luccia formalism for calculating the rate, but leads to a modified interpretation of the bounce solution and a different prediction for the evolution of the system after tunneling. The bounce is seen to correspond to a sequence of configurations interpolating between initial and final configurations on either side of the tunneling barrier, all of which are restricted to the static patch. The final configuration, which gives the initial data on the static patch for evolution after tunneling, is obtained from one-half of a slice through the center of the bounce, while the other half gives the configuration before tunneling. The formalism makes no statement about the fields beyond the horizon. This approach resolves several puzzling aspects and interpretational issues concerning the Coleman-De Luccia and Hawking-Moss bounces. We work in the limit where the backreaction of matter on metric can be ignored, but argue that the qualitative aspects remain in the more general case. The extension to tunneling between anti-de Sitter vacua is discussed.
Comparative analysis of B2L genes in vaccine and wild strains of orf virus in China

Orf is highly contagious zoonoses which is caused by the orf virus (ORFV). In order to determine the characteristics of B2L genes between vaccine strain and wild strain of ORFV in China. In this study we choose the weak vaccine of ORFV produced in biological products (Shandong Taifeng, China) and the wild strain (FJ-PN) isolated and identified in our laboratory to amplify, clone and sequence the B2L genes, and the changes in nucleotide, amino acid and secondary and tertiary protein structure of the B2L proteins were compared and analyzed by bioinformatics software. Comparison results showed that the nucleotide sequence similarity and amino acid sequence similarity of the B2L genes of vaccine strain and wild strain were 98.6% and 98.7% respectively. There was no significant difference between the primary, secondary and tertiary structures of the B2L proteins. The results of this study provide ideas for the study on the function and molecular biological characteristics of related proteins after the ORFV is weakened.
Developing a Criteria Framework for the Evaluation of the Image of the City Case Study: Mansoura Downtown

— Downtowns are important as the open new horizons of development through contribute to the upgrade of traditional communities. The presence of city centers and downtowns has been approved as a major influential component on the image of the city as it can serve as a unifying force in a city or town through triggering force for community enrichment. Lynch [1] described the of this is to develop a criteria framework from different studies and worldwide experiences, using both urban indicators and Lynch's method in the evaluation of urban spaces. This allow urban planners and designers to receive immediate feedback on the relative quality of urban design and perception decisions. The downtown in Mansoura City was as the of this case study. Three observation points were taken along Mansoura downtown and proposed for evaluation. The results show that it is a list of indicators which the axis of the evaluation process
Evaluating the Mediation Role of Job Satisfaction on the Effect of Organizational Justice and Transformational Leadership on Organizational Commitment

The purpose of this study is to uncover the role of job satisfaction in mediating the effects of organizational justice and transformational leadership on organizational commitment. This study was carried out at Sumut Bank in Medan, Indonesia. Purposive sampling was used, with 200 questionnaires distributed. Organizational justice and transformational leadership have a good and significant effect on job satisfaction, according to the findings. Job satisfaction, on the other hand, has a positive and considerable impact on organizational commitment. Job satisfaction has little effect on organizational commitment when it comes to moderating the effects of organizational justice and transformational leadership. The key outcome of this study is that boosting transformational leadership, rather than enhancing organizational justice, will be more effective in increasing organizational commitment.
Dominos and the Gaussian Free Field

We define a scaling limit of the height function on the domino tiling model (dimer model) on simply connected regions in $\mathbf{Z}^2$ and show that it is the “massless free field,” a Gaussian process with independent coefficients when expanded in the eigenbasis of the Laplacian.
Matrix Algorithms, Volume II: Eigensystems

This book is the second volume in a projected five-volume survey of numerical linear algebra and matrix algorithms. This volume treats the numerical solution of dense and large-scale eigenvalue problems with an emphasis on algorithms and the theoretical background required to understand them. Stressing depth over breadth, Professor Stewart treats the derivation and implementation of the more important algorithms in detail. The notes and references sections contain pointers to other methods along with historical comments. The book is divided into two parts: dense eigenproblems and large eigenproblems. The first part gives a full treatment of the widely used QR algorithm, which is then applied to the solution of generalized eigenproblems and the computation of the singular value decomposition. The second part treats Krylov sequence methods such as the Lanczos and Arnoldi algorithms and presents a new treatment of the Jacobi-Davidson method. The volumes in this survey are not intended to be encyclopedic. By treating carefully selected topics in depth, each volume gives the reader the theoretical and practical background to read the research literature and implement or modify new algorithms. The algorithms treated are illustrated by pseudocode that has been tested in MATLAB implementations.
A continuum of expanders

A regular equivalence between two graphs $\Gamma,\Gamma'$ is a pair of uniformly proper Lipschitz maps $V\Gamma\to V\Gamma'$ and $V\Gamma'\to V\Gamma$. Using separation profiles we prove that there are $2^{\aleph_0}$ regular equivalence classes of expander graphs, and of finitely generated groups with a representative which isometrically contains expanders.
Osteoblast Demineralization Induced by Oxidized High-Density Lipoprotein via the Inflammatory Pathway Is Suppressed by Adiponectin

Low mineralization activity by human osteoblast cells (HOBs) indicates abnormal bone remodeling that potentially leads to osteoporosis. Oxidation, the most prominent form of high-density lipoprotein (HDL) modification, is suggested to affect bone mineralization through the inflammatory pathway. Adiponectin, which possesses anti-inflammatory activity, is postulated to have the ability to suppress the detrimental effects of oxidized HDL (oxHDL). This study aimed to investigate the effects of HDL before and after oxidation on markers of mineralization and inflammation. The protective effects of adiponectin on demineralization and inflammation induced by oxHDL were also investigated. OxHDL at 100 µg/mL protein had the highest inhibitory effect on mineralization, followed by lower calcium incorporation. OxHDL also had significantly lower expression of a mineralization marker (COL1A2) and higher expression of inflammatory markers (IL-6, TNF-α, and RELA proto-oncogene, NF-κβ (p65)) compared to the unstimulated control group. These findings suggest that oxHDL reduces the mineralization activity of HOBs by increasing the expression of inflammatory markers. Interestingly, co-incubation of adiponectin and oxHDL in HOBs resulted in higher expression of mineralization markers (ALPL, COL1A2, BGLAP, and RUNX2) and significantly reduced all targeted inflammatory markers compared to the oxHDL groups. On the contrary, HDL increased the expression of mineralization markers (COL1A2 and STAT-3) and exhibited lower expression of inflammatory cytokines (IL-6 and TNF-α), proving the protective effect of HDL beyond the reverse cholesterol transport activity.
Design and Implementation of Lattice-Based Cryptography

Today, lattice-based cryptography is a thriving scientific field. Its swift expansion is due, among others, to the attractiveness of fully homomorphic encryption and cryptographic multilinear maps. Lattice-based cryptography has also been recognized for its thrilling properties: a security that can be reduced to worst-case instances of problems over lattices, a quasi-optimal asymptotic efficiency and an alleged resistance to quantum computers. However, its practical use in real-world products leaves a lot to be desired. This thesis accomplishes a step towards this goal by narrowing the gap between theoretical research and practical implementation of recent public key cryptosystems. In this thesis, we design and implement a lattice-based digital signature, two fully homomorphic encryption schemes and cryptographic multilinear maps. Our highly efficient signature scheme, BLISS, opened the way to implementing lattice-based cryptography on constrained devices and remains as of today a promising primitive for post-quantum cryptography. Our fully homomorphic encryption schemes enjoy competitive homomorphic evaluations of nontrivial circuits. Finally, we describe the first implementation of cryptographic multilinear maps. Based on our implementation, a non interactive key exchange between more than three parties has been realized for the first time, and amounts to a few seconds per party. %%%%La cryptographie a base de reseaux euclidiens est aujourd'hui un domaine scientifique en pleine expansion et connait une evolution rapide et acceleree par l'attractivite du chiffrement completement homomorphe ou des applications multilineaires cryptographiques.

Analysis of mixed discontinuous Galerkin formulations for quasilinear elliptic problems

In this manuscript we present an approach to analyze the discontinuous Galerkin solution for general quasilinear elliptic problems. This approach is sufficiently general to extend most of the well-known discretization schemes, including BR1, BR2, SIPG and LDG, to nonlinear cases in a canonical way, and to establish the stability of their solution. Furthermore, in case of monotone and globally Lipschitz problems, we prove the existence and uniqueness of the approximated solution and the $h$-optimality of the error estimate in the energy norm as well as in the $L_2$ norm.
Scale analysis for an atmosphere flow

In this paper we consider a fluid dynamic model which describes the atmospheric flow and we perform an asymptotic analysis for different time and length scales. In particular we will focus on the two following cases: when the Mach number dominates on the Rossby number yielding an incompressible regime or when the high rotating (low Rossby number) and incompressibility regime act on the same scale ending up with a geostrophic balance. The limit analysis is performed in the ill prepared data setting and therefore we will develop a rigorous and detailed analysis of the local decay and dispersive behavior of the related acoustic waves. Finally we point out, that the set of equations analyzed in the paper may also fit in the artificial compressibility approximation methods.
Semiorthogonal decomposition for algebraic varieties

A criterion for a functor between derived categories of coherent sheaves to be full and faithful is given. A semiorthogonal decomposition for the derived category of coherent sheaves on the intersection of two even dimensional quadrics is obtained. The behaviour of derived categories with respect to birational transformations is investigated. A theorem about reconstruction of a variety from the derived category of coherent sheaves is proved.
