CORPORATE GOVERNANCE, DISCLOSURE QUALITY, AND COST OF EQUITY: EVIDENCE FROM PAKISTAN
Authors: Amanullah Amanullah  , Xinjun Lyu
Published: November 2022

To be successful in the financial world, you must know how the public disclosure of business information affects stock prices. Specifically for Pakistan, this research will help us better understand the relationship between corporate governance, disclosure quality, and equity cost The Sys-GMM model has been employed by 167 non-financial enterprises listed on the Pakistan Stock Exchange since 2017. (PSX). Research shows it was in use between 2018 and 2020. The Sys-GMM technique for estimating may be used to account for endogeneity in corporate governance problems. We discovered that GMM projections failed to account for endogeneity, resulting in inaccurate conclusions, using pooled OLS and fixed-effect estimates. According to the research, the cost of equality and financial transparency are mutually incompatible. All of these factors contribute to the PSE's stock price decline, including board size, concentrated ownership, and CEO duality. The research es-tablishes a relationship between independent audit committees and high-quality audits and reduced equity expenses. Independent directors and competent auditors command a premium on the PSX. The duration of the approval process for financial statements has no bearing on the board's independence. Due to the scarcity of information disclosed in annual reports, investors anticipate a higher rate of return. The conclu-sions of the research may be beneficial to Pakistan's corporate govern-ance authorities and investors.
On the Error-Correcting Performance of some Binary and Ternary Linear Codes
Authors: Baicheva Tsonka
Published: November 2022

In this work, we determine the coset weight spectra of all binary cyclic codes of lengths up to 33, ternary cyclic and negacyclic codes of lengths up to 20 and of some binary linear codes of lengths up to 33 which are distance-optimal, by using some of the algebraic properties of the codes and a computer assisted search. Having these weight spectra the monotony of the function of the undetected error probability after t-error correction P(t)ue (C,p) could be checked with any precision for a linear time. We have used a programm written in Maple to check the monotony of P(t)ue (C,p) for the investigated codes for a finite set of points of p € [0, p/(q-1)] and in this way to determine which of them are not proper.

Transparent Scheduling of Composite Web Services
Authors: Dyachuk Dmytro , Deters Ralph
Published: November 2022

Composite Web Services (CWS) aggregate multiple Web Services in one logical unit to accomplish a complex task (e.g. business process). This aggregation is achieved by defining a workflow that orchestrates the underlying Web Services in a manner consistent with the desired functionality. Since CWS can aggregate atomic and other CWS they foster the development of service layers and reuse of already existing functionality. An important issue in the deployment of services is their run-time performance under various loads. Due to the complex interactions of the underlying services, a CWS they can exhibit problematic and often difficult to predict behaviours in overload situations. This paper focuses on the use of request scheduling for improving CWS performance in overload situations. Different scheduling policies are investigated in regards to their effectiveness in helping with bulk arrivals.
On Proactive Verifiable Secret Sharing Schemes
Authors: Nikov Ventzislav , Nikova Svetla , Preneel Bart
Published: November 2022

This paper investigates the security of Proactive Secret Sharing Schemes. We first consider the approach of using commitment to 0 in the renewal phase in order to refresh the player's shares and we present two types of attacks in the information theoretic case. Then we prove the conditions for the security of such a proactive scheme. Proactivity can be added also using re-sharing instead of commitment to 0. We investigate this alternative approach too and describe two protocols. We also show that both techniques are not secure against a mobile adversary. To summarize we generalize the existing threshold protocols to protocols for general access structure. Besides this, we propose attacks against the existing proactive verifiable secret sharing schemes, and give modifications of the schemes that resist these attacks.

Pushing the Quality Level in Networked News Business: Semantic-Based Content Retrieval and Composition in International News Publishing
Authors: Schranz Markus
Published: November 2022

Electronic publishing exploits numerous possibilities to present or exchange information and to communicate via most current media like the Internet. By utilizing modern Web technologies like Web Services, loosely coupled services, and peer-to-peer networks we describe the integration of an intelligent business news presentation and distribution network. Employing semantics technologies enables the coupling of multinational and multilingual business news data on a scalable international level and thus introduce a service quality that is not achieved by alternative technologies in the news distribution area so far. Architecturally, we identified the loose coupling of existing services as the most feasible way to address multinational and multilingual news presentation and distribution networks. Furthermore we semantically enrich multinational news contents by relating them using AI techniques like the Vector Space Model. Summarizing our experiences we describe the technical integration of semantics and communication technologies in order to create a modern international news network.

Quality Measurement of Business Web Application
Authors: Tarcsi Ádám
Published: November 2022

With the development of the Internet culture applications are becoming simpler and simpler, users need less IT knowledge than earlier; from the ‘reader’ status they have reached that of the content creator and editor. In our days, the effects of the web are becoming stronger and stronger— computer-aided work is conventional almost everywhere. The spread of the Internet applications has several reasons: first of all, their accessibility is widespread; second, their use is not limited to only one computer or network on which they have been installed. Also, the quantity of accessible information now and earlier is not even comparable. Not counting the applications which need high broadband or high counting capacity (for example video editing), Internet applications are reaching the functionality of the thick clients associates. The most serious disadvantage of Internet applications – for security reasons — is that the resources of the client computer are not fully accessible or accessible only to a restricted extent. Still thick clients do have some advantages: better multimedia perdormance with more flexibility due to local resources and the possibility for offline working.
Parallel Class Intersection Matrices of Orthogonal Resolutions
Authors: Zhelezova Stela
Published: November 2022

Parallel class intersection matrices (PCIMs) have been defined and used in [6], [14], [15] for the classification of resolvable designs with several parameter sets. Resolutions which have orthogonal resolutions (RORs) have been classified in [19] for designs with some small parameters. The present paper deals with the additional restrictions that the existence of an orthogonal mate might impose on the PCIMs of a resolution, and with the effect of both PCIMs usage and the methods for RORs construction described in [19] and [20]. It is shown in several examples how consideration of PCIMs can result in constructing only of solutions which can have orthogonal mates, and thus substantially improve the computation time. There are parameters for which PCIMs make the classification of RORs possible, and also cases when PCIMs directly prove the nonexistence of doubly resolvable designs with certain parameters.
Constructing a Canonical form of a Matrix in Several Problems about Combinatorial Designs
Authors: Mateva Zlatka Teneva
Published: November 2022

The author developed computer programs needed for the classification of designs with certain automorphisms by the local approach method. All these programs use canonicity test or/and construction of canonical form of an integer matrix. Their efficiency substantially influences the speed of the whole computation. The present paper deals with the implemented canonicity algorithm. It is based on ideas used by McKay, Meringer, Kaski and Bouyukliev, but while their algorithms are for the equivalence test, the canonicity test or finding canonical representative of only one type of combinatorial object (graph, code, design, binary matrix, etc.), the algorithm presented in this paper is meant to work fast on all types of integer matrices used for the classification of designs with predefined automorphisms. This is achieved through the suitable spectrum invariant, and the way it is used to cut off some branches of the search tree.

Authors: Paneva-Marinova Desislava
Published: November 2022

This paper presents dissertation work on semantic-oriented architectures and models for personalized and adaptive access to the knowledge in a multimedia digital library. The work was presented on October 27, 2008 before the Specialized Academic Council in Informatics and Mathematical Modelling at the Higher Attestation Commission. As a result of the work there appeared a functional module providing customized user access to the library content flow. The module used an IEEE PAPI and IMS LIP-oriented ontological user model. The main services provide customized user access, browsing, searching, and grouping of digitised objects and collections, user profile management, tracking the user’s behaviour, etc. The services require and trace out data about the preliminary level of the users’ knowledge in the domain covered by the digital library, their object observation style, cognitive goals and interests, preferences about the objects/collections presentation and grouping, physical limitations, used knowledge delivery channels (Web, mobile phone), etc. Then they transform the available digitised objects into a new personalized form, and finally deliver them to the user. The module uses special usage scenarios/instructions defining a wide range of service actions dependent on the user’s background, events, informal learning situations, knowledge delivery channels, etc.

Reasoning Methods for Designing and Surveying Relationships Described by Sets of Functional Constraints
Authors: Demetrovics János , Molnár András , Thalheim Bernhard
Published: November 2022

Current methods of database schema design are usually based on modeling the real world as entity (or object) classes with relationships among them. Properties of relationships can be described by semantical database constraints. One of them is functional dependency, which has a key role in traditional database design. The three basic types of binary relationships that can be described by functional dependencies are one-to-one, one-to-many and many-to-many. They can also be expressed by common graphical languages like the Entity-Relationship (ER) graph. However, relationships defined among more than two entity classes (ternary, quaternary, etc.) are usually not investigated and the common graphical tools lack expressive power regarding them. We show that the variety of relationship types is rich for higher arities and propose a simplified formalism for functional constraints as well as graphical and spreadsheet reasoning methods for handling sets of functional constraints that also help by relationship design.

Development and Implementation of NURBS Models of Quadratic Curves and Surfaces
Authors: Petkov Emiliyan G.
Published: November 2022

This article goes into the development of NURBS models of quadratic curves and surfaces. Curves and surfaces which could be represented by one general equation (one for the curves and one for the surfaces) are addressed. The research examines the curves: ellipse, parabola and hyperbola, the surfaces: ellipsoid, paraboloid, hyperboloid, double hyperboloid, hyperbolic paraboloid and cone, and the cylinders: elliptic, parabolic and hyperbolic. Many real objects which have to be modeled in 3D applications possess specific features. Because of this these geometric objects have been chosen. Using the NURBS models presented here, specialized software modules (plug-ins) have been developed for a 3D graphic system. An analysis of their implementation and the primitives they create has been performed.

Quasi-Monte Carlo Methods for some Linear Algebra Problems. Convergence and Complexity
Authors: Karaivanova Aneta
Published: November 2022

We present quasi-Monte Carlo analogs of Monte Carlo methods for some linear algebra problems: solving systems of linear equations, computing extreme eigenvalues, and matrix inversion. Reformulating the problems as solving integral equations with a special kernels and domains permits us to analyze the quasi-Monte Carlo methods with bounds from numerical integration. Standard Monte Carlo methods for integration provide a convergence rate of O(N^(−1/2)) using N samples. Quasi-Monte Carlo methods use quasirandom sequences with the resulting convergence rate for numerical integration as good as O((logN)^k)N^(−1)). We have shown theoretically and through numerical tests that the use of quasirandom sequences improves both the magnitude of the error and the convergence rate of the considered Monte Carlo methods. We also analyze the complexity of considered quasi-Monte Carlo algorithms and compare them to the complexity of the analogous Monte Carlo and deterministic algorithms.
Effect of walking to the operating room on preoperative anxiety in patients scheduled for outpatient laser therapy for venous insufficiency. A monocentric randomized study
Authors: Samalea Suarez N , Hallet C , Lois F , Joris J , Brichant J.F.
Published: November 2022

Background: Preoperative anxiety in day surgery is associated with a higher incidence of post-operative complications such as postoperative nausea and vomiting, pain or unplanned admission. Objectives: To evaluate the effect of walking to the operating room (OR) on anxiety in ambulatory patients undergoing minimal invasive laser therapy for venous insufficiency. Design and setting: Randomized study in a tertiary hospital between May and November 2019. Methods: 100 patients scheduled for ambulatory laser therapy for venous insufficiency were included. Patients were randomized to walk to the OR (study group, n=50) on even weeks or to lie in a bed to the OR (control group, n=50) on odd weeks. Main outcome measures: Baseline anxiety was assessed using the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and Numerical Rating Scale of anxiety (anxiety-NRS) from 0 to 10 when prepared for departure to OR. Preoperative anxiety-NRS assessment was performed upon arrival in the OR. Results: Patients’ characteristics were similar in both groups. Baseline anxiety-NRS was significantly lower in the study group than in the control group: 2 (1-3) vs. 4 (2-6.5) (p=.013) respectively. No difference was observed between the groups for preoperative anxiety-NRS. A significant reduction in anxiety-NRS on arrival at the OR was observed in the control group compared with the study group (p=.019). Conclusion: Walking to the OR does not reduce anxiety in ambulatory patients undergoing minimal invasive laser therapy for venous insufficiency. But, preparing them to walk to the OR could possibly reduce baseline anxiety while waiting for surgery.
The effect of digital nerve block on the accuracy of hemoglobin monitoring during surgery: A randomized clinical trial
Authors: Moharari R.S. , Davani B.M. , Pourfakhr P , Nooraie R.Y. , Khajavi M.R. , Etezadi F , Najafi A
Published: November 2022

Background: The decision to transfuse blood products to patients during surgery is critical, due to the potential complications and costs of transfusion. Measuring hemoglobin level by spectrophotometry (SpHb) plays an important role in making this decision. The accuracy of SpHb depends on the finger perfusion. Since digital nerve blocks (DNB) can enhance blood circulation, we aimed at investigating DNB effects on the accuracy of SpHb.

Methods: Patients undergoing spine surgery were randomly assigned to two groups. Group A received DNB in the left hand, and group B received DNB in the right hand. In each group, the other hand was considered as the control. Rainbow adult ReSposable sensors were attached to the patients’ both hands. Before surgical incision and every 1.5 hours, the SpHb values of both hands and the perfusion index were recorded. Concomitantly, arterial blood samples were drawn and sent to the lab for hemoglobin concentration measurement. This served as the gold standard for assessing hemoglobin levels (labHb). We used a mixed-effects generalized linear model to test the effect of independent variables on the difference between SpHb and labHb at each time point.

Results: The SpHb displayed higher hemoglobin levels than those assessed by the lab. For lower labHb values, the SpHb-labHb differences were larger. A one-unit decrease in labHb increased the difference between SpHb and labHb by 0.56 g dL -1 , which was statistically significant.
DNB significantly increased the difference between SpHb and labHb by 0.42 g dL -1 . The effect of DNB on the difference between SpHb and labHb was significant up to three hours after the beginning of surgery (0.58 g dL -1 difference between blocked and non-blocked hands).

Conclusion: This study shows that, when hemoglobin levels are low, the accuracy of spectrophotometry decreases. Although DNB increases finger perfusion, it leads to an overestimation of hemoglobin levels by SpHb.
Surgical adrenalectomy during rescue Extracorporeal Life Support for pheochromocytoma induced cardiogenic shock: a case report
Authors: Gruyters I , Stessel B , Yilmaz A , Vekemans K , Heye S , Timmermans Ph. , Vandenbrande J
Published: November 2022

Introduction : Pheochromocytoma, a rare catecholamine-producing tumor, has been described to provoke stress-induced Takotsubo-like cardiomyopathy and even severe refractory cardiogenic shock. In this case report, venoarterial extracorporeal membrane oxygenation (VA-ECMO) was used for hemodynamic stabilization and was continued during the resection of a large neuroendocrine tumor.

Description : A 69-year old male, recently diagnosed with a pheochromocytoma, was referred to our center because of severe cardiogenic shock after induction of anesthesia for resection of the mass. Despite adequate alpha-and beta-adrenergic blockade for one month, he developed malignant hypertension with subsequently hemodynamic collapse. After successful cardiopulmonary resusci-tation he developed pulmonary oedema with severe hypoxemia and persistent hemodynamic lability. On arrival in our hospital, echocardiography revealed significant left ventricular impairment. Decision was made to commence him on VA-ECMO for a refractory cardiogenic shock with severe pulmonary oedema. Because of persistent blood pressure swings despite VA-ECMO and beta-adrenergic blockade, we decided to remove the tumor on mechanical circulatory support by an open surgical approach the next day. After clamping of the adrenal circulation, the patient experienced profound hypotension requiring high doses of epinephrine and a methylene blue infusion. Surgical resection was successful but complicated by a postoperative bleeding for which the patient underwent an emergent endovascular embolization of an adrenal artery. Over the next days, there was progressive cardiac recovery and the patient was weaned off VA-ECMO on the fourth postoperative day. The patient was discharged from the intensive care 27 days after admission and left the hospital on day 30.

Discussion: VA-ECMO seems to be a feasible last resort therapy in refractory cardiogenic shock induced by pheochromocytoma crisis as suggested by a high survival rate in literature. Despite its support benefit during this type of shock, surgical removal of the tumor is rarely done with mechanical circulatory support and heparinization.

Authors: Snow Nicholas H.
Published: November 2022

In this installment of “GC Connections,” we take a close look at Golay’s famous equation that most people view as relating to height equivalent to a theoretical plate (HETP) to the carrier gas flow rate or average linear gas velocity in a capillary column. We explore the original works of Golay and Keulemans. We also look closely at the original equation, the assumptions involved with its development, and the assumptions (both good and bad) that have been applied to HETP over the years. In part two, we will explore the consequences and relevance of this theory today, with temperature programming, very long (and very short) columns, high pressure drops, and vacuum outlet detectors.

Cooperative behavior in biological networks is discouraged if defectors reap shared benefits. An obvious counterstrategy used by individuals is to avoid defectors by moving into another habitat. For spatially arranged ecological communities, mathematical analysis of the so-called snowdrift game shows under which circumstances this strategy has beneficial outcomes.

Penelitian ini bertujuan untuk mengetahui hubungan lama waktu sexing dengan kualitas spermatozoa sapi bali (Bos sondaicus) pada medium sexing tris-kuning telur. Rancangan yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) yang terdiri atas 3 perlakuan (lama waktu sexing) dan setiap perlakuan terdiri atas 6 ulangan (frekuensi penampungan). Perlakuan yang digunakan dalam penelitian ini adalah : P1 (waktu sexing 20 menit), P2 (waktu sexing 30 menit), P3 (waktu sexing 40 menit). Semen yang digunakan dalam penelitian ini berasal dari sapi pejantan milik Unit Pelaksanaan Teknis Daerah (UPTD) Perbibitan Ternak dan Pakan Ternak Kecamatan Konda dimana terlebih dahulu dilakukan penampungan semen yang dilanjutkan dengan prosedur sexing spermatozoa menggunakan medium sexing Tris-Kuning Telur dengan durasi yang berbeda sesuai perlakuan. Parameter yang diamati dalam penelitian ini adalah konsentrasi spermatozoa, persentase motilitas, persentase viabilitas dan persentase membran plasma utuh (MPU). Berdasarkan hasil penelitian, lama waktu sexing yang berbeda sangat berpengaruh (P<0.01) terhadap konsentrasi spermatozoa dan persentase motilitas spermatozoa setelah sexing namun tidak berpengaruh (P>0.05) terhadap persentase viabilitas dan persentase membran plasma utuh (MPU) spermatozoa.

Ayam broiler merupakan salah satu ternak unggas penghasil daging yang berpotensi sebagai bahan pangan sumber protein untuk memenuhi kebutuhan gizi masyarakat. Penelitian ini bertujuan untuk mengetahui bobot potong, persentase karkas dan lemak abdominal ayam broiler yang diberi tepung usus ayam broiler dengan level berbeda. Penelitian dilaksanakan selama 35 hari mulai dari bulan Juli sampai Agusutus 2019 bertempat di Desa Watunggarandu, Kecamatan Lalonggasumeeto, Kabupaten Konawe, Selawesi Tenggara. Penelitian ini mengunakan 96 ekor ayam broiler dengan menggunakan  rancangan acak lengkap (RAL) dengan 4 perlakuan dan 4 ulangan yaitu P0 (perlakuan kontrol), P1 ( 3% tepung usus ayam), P2 (6% tepung usus ayam), P3 (9% tepung usus ayam) dan masing-masing  perlakuan diulang 4 kali. Variabel yang diamati pada penelitian yaitu bobot potong, persentase karkas dan lemak abdominal. Data hasil penelitian dianalisis dengan menggunakan analisis sidik ragam (analysis of  variance) dan jika perlakuan berpengaruh nyata  maka akan dilanjutkan dengan uji beda antar perlakuan dengan menggunakan DMRT (Duncan Multiple Range Test). Hasil penelitian menunjukkan bahwa pemberian tepung usus ayam broiler tidak berpengaruh nyata (P>0,05)  terhadap bobot potong, persentase karkas dan lemak abdominal ayam broiler. Tepung usus ayam broiler dapat digunakan sebagai pakan alternatif penganti tepung ikan.

Penampilan Produksi Burung puyuh dipengaruhi oleh banyak faktor, salah satu diantaranya adalah pakan. Pakan tambahan (feed additive) berupa herbal seperti daun katuk diduga dapat menunjang produktivitas puyuh. Tujuan dari penelitian ini adalah untuk mengetahui penampilan produksi burung puyuh (Coturnix-coturnix japonica) umur 2-7 minggu yang diberi tepung daun katuk. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 4 (empat) perlakuan dan 5 (lima) ulangan. Variabel yang diamati dalam penelitian ini yaitu konsumsi pakan, pertambahan bobot badan, dan konversi pakan. Hasil penelitian menunjukan bahwa pemberian tepung daun katuk tidak memberikan pengaruh yang nyata (P>0,05) terhadap konsumsi pakan, pertambahan bobot badan, dan konversi pakan puyuh umur 2 – 7 minggu. Puyuh perlakuan dalam penelitian ini memiliki konsumsi pakan 11,96 gr/hari, PBB yaitu 2,68 gr/hari, dan konversi pakan 4,59. Kesimpulan dalam penelitian ini yaitu Pemberian tepung daun katuk hanya efektif pada level 5%, karena menunjukan produktivitas yang lebih baik dibandingkan dengan pemberian diatas 5% maupun tanpa pemberian tepung daun katuk.
