Perturbation Analysis of the Algebraic Metric Generalized Inverse in Lp(Ω,μ)

ABSTRACT Let X = Lp(Ω,μ) (1<p<∞) and T,δT:X→X be bounded linear operators. Put . In this paper, using the notion of quasi-additivity and the concept of stable perturbation, we will give some estimates of the upper bound of in terms of the gap function. As an application of main results, we also investigate the best approximate solution problem of ill-posed operator equation.
Generalized junction conditions for degenerate parabolic equations

In this paper, we study degenerate parabolic equations in non-divergence form whose " coefficients " are discontinuous along interfaces. At these discontinuities, the imposed conditions are compatible with the maximum principle but they do not rely on any compatibility of coefficients across interfaces. An important and simple example is when the equation is posed in the Euclidian space and when " coefficients " are smooth on either side of a hyperplane. There are also some motivations for solving such partial differential equations on networks, and in particular on junctions, that are the networks made of one vertex and a finite number of infinite edges. We explain here that the approach proposed by the first author and Monneau (2014) for Hamilton-Jacobi equations can be further developed to handle generalized junction conditions (such as the generalized Kirchoff ones) and second order terms. We first prove that generalized junction conditions reduce to flux-limited ones, which are of control-type. We then use the vertex test function (Imbert, Monneau – 2014) to prove a comparison principle. These results extend naturally to the multi-dimensional setting and to stationary solutions. We apply our results to two different multi-dimensional problems. On the one hand, we give a complete answer to an open question about these equations: we determine the vanishing viscosity limit associated with Hamilton-Jacobi equations posed on multi-domains and networks. In the two-domain and convex case, the maximal Ishii solution identified by Barles, Briani and Chasseigne (2012) is selected. On the other hand, we give a short and simple PDE proof of a large deviation results of Boue, Dupuis and Ellis (2000).
A Discrete Mechanical Model of 2D Carbon Allotropes Based on a 2nd-Generation REBO Potential: Geometry and Prestress of Single-Walled CNTs

Predicting the natural equilibrium radius of a single - walled Carbon NanoTube (CNT) of given chirality, and evaluating - if any - the accompanying prestress state, are two important issues, the first of which has been repeatedly taken up in the last decade or so. In this paper, we work out both such a prediction and such an evaluation for achiral (that is, armchair and zigzag) CNTs, modeled as discrete elastic structures whose shape and volume changes are governed by a Reactive Empirical Bond-Order (REBO) interatomic potential of second generation. The basic kinematic variables we choose are bond lengths, bond angles, and dihedral angles; to each of these variables we associate a work-conjugate nanostress. In previous studies, neither dihedral angles were considered nor a REBO potential of the type proposed by Brenner et al. was used. We show that achiral nanotubes, in their natural state, are prestressed structures: the nanostresses associated with changes in bond lengths are null, but the nanostresses associated with changes in bond and dihedral angles are not. Our results convincingly compare with the results reported in those previous works where single-walled CNTs were not naively modeled as if it where possible, at least in principle, to roll them up from a monolayer graphene sheet.
Does Board Gender Diversity Moderatively Affect the Relationship Between Business Characteristics and Corporate Sustainability Performance?

Business sustainability is a process of increasing the positive impacts, while at the same time, is expected reducing negative effects of operations in order to achieve sustainable economic, social, and environmental performance. This study aims to examine how company characteristics, company size and indutry type, impact corporate sustainability performance refers to Triple Bottom Line concept. Further, whether the impacts are moderated by board gender diversity. Using partial least square – structural equation modeling (PLS-SEM) to asses the panel data consists of 18 Indonesian companies from participant of Asia Sustainability Reporting Rating (ASRR) extracted on National Center Sustainability Reporting (NCSR) website during observation period 2017–2019. The empirical finding reveals that company characteristics – size and industry type, both significantly impact the performance of corporate sustainability in different ways. This shows a solid evidence that stakeholder demands has shifted business behavior through implementation of sustanability practices. In moderating role, the low persentage women on board shows no influence on corporate sustainability performance, as presence of female directors on corporate boards level only compliance role as corporate governance mechanism. Hence, we should consider to increase the proportion of women on board level as female chairperson offers new perspectives and skills set in business decision making process to enhance sustainable value in the long run.
Beneath the Surface: Identifying Subsurface Caves in "Gua Pandan" Using Integrated Electrical Profiling Method

One of the geopark tourism areas in East Lampung Regency, "Gua Pandan," has run into rock subsidence on the surface. As part of the subsidence prevention, indirect electrical methods between resistivity and chargeability profiling were applied to identify the presence of a subsurface cave in the study area. Two measurement lines were carried out with Wenner Alpha and Wenner Schlumberger arrays. Because the depth target is shallow (approximately 10 m) and to obtain a better resolution, each line has a stretch length of 70 m and 2 m electrode spacing. A line was measured over a known underground cave to produce a desired outcome, and the other was in an area with no cavities. Based on the results from each profile of resistivity and chargeability, an air-filled target has a value of over 5,000 and under 6 ms, respectively. Then, integrated processing of both methods generated a metal factor (MF) profile to view the presence and estimated shape of the cave/ cavities. The result represents that an MF value under 1.5 ms/Ωm is a cavity, and solid rock is over 1.5 ms/Ωm. Also, the MF level from both configurations delineates a similar section. However, a modest difference occurs in estimating the cavity shape geometry, for Wenner Apha and for Wenner Schlumberger. Furthermore, this study can be an initial step in safety assessment in the area.

Modeling Price Formation in a Multi-Commodity Market - A Graph-Theoretical Decomposition Approach to Complexity Reduction

This thesis presents an optimization model to simulate the global price formation of multiple commodities over multiple time periods. The model considers the connection of commodities through their production processes. The supply side maximizes its total profit taking account of the price-demand relationships of all products. The variables of this model are production quantities, transport quantities, storage quantities, and commodity prices. We apply the model to a part of the petrochemical market. A large multi-commodity model requires many parameters. Moreover, the interpretation of the simulation results can become difficult. Therefore, this thesis focuses on the model and complexity reduction with respect to optimization models. We propose a graph-theoretical approach to reveal the structure of large block-separable problems and to compare different decompositions into subproblems. The connections between primal and dual variables of a constrained optimization problem are represented on a hypergraph, which can be analyzed and beneficially partitioned using appropriate graph-theoretical methods. We show how different partitions of the hypergraph constitute different decompositions of the optimization problem. Furthermore, we address the approximation of subproblems. The decomposition approach is adapted to the commodity market model. We formulate the subproblems for chosen sets of products and processes and present an algorithm for the automated identification of model components that are suited for an aggregation. The aggregation of components of the market model in terms of approximating subproblems is discussed from different points of view. Furthermore, we conduct sensitivity analyses within the overall problem and within subproblems. The numerical results of the application to a petrochemical market model reveal different possibilities of model reduction.
Zeroing dynamics based motion control scheme for parallel manipulators

Zeroing dynamics (ZD), as a powerful method proposed for time-varying problems solving, has found successful applications in motion control of serial manipulators. Compared with serial manipulators, parallel manipulators possess some attractive advantages such as high carrying capacity and high operation accuracy. However, the inherent differences between parallel and serial manipulators set great difficulties on the applications of ZD to the control of parallel manipulators. Making progress along this direction, the first ZD based motion controller of parallel manipulators is proposed and the design procedure of the ZD based scheme is presented. As a typical application, the proposed scheme is utilised to control a Stewart platform for tracking a quatrefoil-shaped path, which illustrates the effectiveness of the ZD based scheme.
Morphology and pitcher's color Nepenthes in Batu Lubang Sibolga Area, North Sumatra Province, Indonesia

Abstract. Tarigan MRM, Aziz S, Tanjung IF, Pary C, Adlini MN, Jayanti UNAD, Ardianto, Ulfa AY. 2023. Morphology and pitcher's color Nepenthes in Batu Lubang Sibolga Area, North Sumatra Province, Indonesia. Biodiversitas 24: 1953-1962. The study's objective was to identify the size, color, and shape of a pitcher of Nepenthes found in the Batu Lubang Sibolga region. Purposive sampling is used as part of an exploratory approach in this study. Plot-based Nepenthes observation was conducted in the Sitahuis District, Central Tapanuli Regency, North Sumatra Province, Indonesia, to examine pitcher morphology and color. The results showed two species of Nepenthes, namely N. gracilis Korth and N. eustachya Miq, with two types of pitchers each, namely the lower and upper pitcher. The morphology of the Nepenthes pitchers has an almost similar shape but differs in the size of the pitcher circumference, where the lower pitcher is smaller than the upper pitcher. The bottom pitcher of N. gracilis has redwood (45%), and the upper pitcher is light green (55%), according to the proportion of observations of the color of the lower and upper pitchers of these two species. While the upper pitcher of N. eustachya is green with red dots (70%), the lower pitcher is light reddish green (30%). According to the study's findings, Nepenthes in the Batu Lubang Sibolga area required conservation intervention to preserve this species.
NEAR-INFRARED OBSERVATIONS OF SiO MASER-EMITTING ASYMPTOTIC GIANT BRANCH (AGB) STARS

Near-infrared (NIR) monitoring observations of asymptotic giant branch stars exciting bright SiO masers have been made with the 1 m telescope of Kagoshima University. In order to investigate the properties of these stars and their envelopes, we combined our NIR photometric data with mid- and far-infrared flux data obtained by the IRAS satellite, SiO maser flux data provided by the Nobeyama Radio Observatory, visual magnitude data provided by the AAVSO, and the reported data on the expansion velocities of the circumstellar envelopes. The absolute magnitudes at the K-band and the distances are estimated using the period–luminosity relation of Mira variables determined by Feast et al. Then, mass-loss rates and isotropic luminosities of an SiO maser are estimated. The mass-loss rates range from approximately 10−8 M ⊙ yr − 1 ? > to over 10−5 M ⊙ yr − 1 ? > . We found that the NIR pulsation amplitudes are correlated with the pulsation periods and the observed wavelengths. We also found correlations of the isotropic luminosities of SiO masers with the mass-loss rates and absolute magnitudes at the K-band. These results will help us to understand the pumping mechanism of SiO masers. We measured, for the first time, the periods and/or NIR magnitudes of TX Cam, BW Cam, IRAS 06297+4045, IRAS 18387–0423, and RT Cep.

Impact of Water Treatment on Anemia in Hemodialysis Patients

Introduction: The microbiological quality of water in the dialysate used in hemodialysis has been suggested as a contributor to inflammation, and a link between dialysate purity, inflammation, and responsiveness to erythropoietin therapy has been suggested in many studies. The level of endotoxin might induce inflammation and resistance to erythropoietin therapy in dialysis patients. We aimed to compare the effect of using the central dialysis fluid delivery system (CDDS) versus the single-patient dialysis fluid delivery system (SPDDS) on anemia in prevalent hemodialysis patients. Methods: In a prospective cohort study, 100 adult prevalent hemodialysis patients with T-SAT ≥20% were divided into two equal groups: CDDS and SPDDS. Endotoxin in water sample and routine investigations (hemoglobin, serum Ca+, serum Po4−, PTH, and urea level) were done. CRP, erythropoietin resistivity index (ERI), and erythropoietin stimulating agents (ESAs) doses were assessed repeatedly to assess inflammatory and anemia states. Results: Endotoxin level in the dialysis fluid of the CDDS group was significantly lower compared to the SPDDS group (0.05 vs. 0.11 EU/ml, P = 0.001). CRP level decreased significantly after 3 months in the CDDS group (P < 0.001) compared to the SPDDS group (P = 0.54), with significant improvement in the hemoglobin level and ERI at 3 months in the CDDS group and decrease in ESA requirements. Conclusion: Improvement in dialysis liquid purity reduces inflammatory markers in prevalent hemodialysis patients, improves ERI, and decreases ESA requirements in renal anemia.
Lexical and Grammatical Features of Memoranda of Agreement (MOA) on Academic Partnerships

In the past decades, internationalization has become a byword in many educational institutions. Higher education institutions are aware that a means by which they can offer good quality education is by engaging in partnerships with international institutions. International linkages established by academic institutions have a wider reach such that teaching and learning, research, community, and extension programs may have an international flavor. In forging partnerships, institutions would sign an agreement called the Memorandum of Agreement (MOA), which stipulates provisions expected from the parties involved. Employing the framework of Johnson and Coulthard (2010) on the linguistic features of legal documents, the study examined 20 local and international MOAs on academic partnerships. Findings revealed that seven out of the 11 linguistic features abound in the local MOAs. These are binomial expressions; generic/cognitive structuring; legal archaisms; modality; negators; sentence length and complexity; and specialized, distinctive, and technical legal lexis. For international MOAs, only four out of the 11 linguistic features were found to be notable. These are generic/cognitive structuring, modality, negators, and sentence length and complexity. These features were found to occur at least 50 times or more in the contracts, which may cause ambiguity to the readers. Finally, with the dearth of studies using agreements as corpus, it is recommended that other types of agreement be examined, such as non-disclosure agreement, cooperative agreement, confidentiality agreement, intellectual property assignment agreement, among others. Other linguistic features may also be investigated, such as lexical repetition, formulaic expressions, French words and Latinisms, syntactic discontinuities, performative verbs, and euphemisms.
The Impact of English Language on Business Communication in Asia: A Scoping Review

In the current global era, English is becoming increasingly essential not only as a worldwide language but now widely used as a business language in native and non-native English-speaking countries. Particularly, English language proficiency is mostly required and recognized amongst the countries in the n continent. Thus, this review emphasises the importance of the English language, the dynamism of ways that may be utilised when teaching the English language and identifying the requirements of English language skills among business workers and students. Hence, the primary goal of this scoping review is to uncover previous research on the impact of the English language on business communication in Asia. This scoping review was reported according to Preferred Reporting Items for Systematic Reviews for Scoping Reviews (PRISMA-ScR) guidelines. Five databases, namely Education Resources Information Center (ERIC), Semantic Scholar, ScienceDirect, Directory of Open Access Journals (DOAJ), and SAGE Journals, were used for data scoping. A total of 10 studies were identified to be eligible for selection.
Diversity, Inequality and Predictive Power: Why Do Colleges Go SAT Optional?

Standardized testing is a controversial topic that has gained national attention from the press. Testing is an issue that impacts students from the moment that they enter the school system. The emphasis on testing follows students throughout elementary, middle and high school, culminating with college entrance exams at the end of their high school career. The SAT and ACT are the most commonly used assessments to gain admission to a college or university in the United States. There is a movement in higher education to adopt test optional policies. The implications of test optional policies have not been examined extensively. Previous research suggests that SAT optional policies increase an institution’s selectivity rate, but does not enhance diversity (Belasco et. al 2014). This study examines the relationship between test optional policies and diversity rates and assesses how colleges rationalize the decision to transition. Diversity, Inequality and Predictive Power: Why Do Colleges Go SAT Optional?
A Laser Synthesis Route to Boron‐Doped Gold Nanoparticles Designed for X‐Ray Radiotherapy and Boron Neutron Capture Therapy Assisted by CT Imaging

New multifunctional theranostic vectors allow the expansion of cancer therapeutic approaches toward scarcely investigated fields. One example is the combination of boron neutron capture therapy (BNCT) and X‐ray radiotherapy (XRT) for treating normal and XRT‐resistant hypoxic tumor regions and reduce recurrence. Of great relevance for BNCT is also the support of viable, rapid, safe, and reliable techniques for the localization and quantification of the radiosensitizers in the tissues. To address these challenges, polymer‐coated Au‐B nanoparticles (NPs) are obtained starting from a laser ablation in liquid process. Despite thermodynamic constraints, the two elements coexist by short‐range boron segregation in the gold lattice, as demonstrated experimentally and explained with the support of density functional theory calculations. Thus, the Au‐B NPs maintain a marked gold character such as biocompatibility, stability, and straightforward surface chemistry with thiolated compounds, desirable for the integration with agents capable of cell targeting and internalization. Overall, the Au‐B NPs exhibit the appropriate features for the investigation of combined BNCT and XRT, supported by the localization and quantification with X‐ray computed tomography imaging. Besides, the Au‐B nanotechnology tool is achievable without renouncing to reproducibility, environmental sustainability, and cost affordability thanks to the laser‐assisted synthetic pathway.
Simple Distributed Filtering on a CLP Platform

The area of distributed constraint satisfaction has drawn significant attention in the past decade. The approaches proposed in the area can be classified in two large categories: distributed search techniques and distributed filtering techniques. The work described in this paper concerns the CLP implementation of the Dis-SAC algorithm, a novel distributed filtering technique that is based on the singleton consistency algorithm. The advantages of the algorithm include a high pruning efficiency and a remarkable simplicity. The latter allows an unproblematic implementation of the algorithm in any constraint programming platform that supports network communication, without the need of tampering with the (low level) consistency algorithm employed. The present paper briefly describes Dis-SAC along with its implementation in the Cspcons distributed CLP platform and presents experimental results on a number of structured constraint problems. The motivation behind this work is twofold: to support our argument concerning the simple implementation of the algorithm and to further investigate the benefits of its application to constraint satisfaction problems. keywords: Constraint Satisfaction, Distributed AI, Logic Programming
