Trong việc tính toán chi phí vốn trung bình cho các dự án đầu tư, một thành phần quan trọng là gia trọng dành cho các nguồn vốn trong cơ cấu. Theo cách tính truyền thống WACC, các gia trọng này sẽ được tính dựa trên giá trị thị trường của các nguồn vốn trong cấu trúc. Tuy nhiên, với các hợp đồng cho vay vốn đối với doanh nghiệp trách nhiệm hữu hạn, người cho vay đã đồng thời đính kèm vào đó một quyền chọn. Giá trị quyền chọn này không được phương pháp truyền thống tính toán và điều chỉnh. Điều này khiến việc tính toán các gia trọng có thể không được chính xác. Bài viết này trình bày cách dùng phương pháp của Black – Scholes để định giá các quyền lựa chọn tiềm ẩn này. Từ đó, ta có thể tính chính xác hơn gia trọng cho từng loại nguồn vốn trong cấu trúc vốn để tính lãi suất WACC thích hợp.

Published: September 2023

In this paper we present two new extensions of Korpelevich's extragraclient method for solving the scalar Quasi-Equilibrium Problem (QEP) in Euclidean space. In both extensions we replace the second orthogonal projection in the correction step of the extragradient method by an Armijo linesearch adapted to (QEP). We show that in both extensions we obtain, under mild conditions and without a Lipschitz condition, the global convergence of our iterative methods for computing a quasi-equilibrium solution.

THE ROLE OF EDUCATION IN ENSURING NATIONAL SECURITY: TRAINING OF SCIENTIFIC PERSONNEL FOR THE ARMED FORCES OF UKRAINE
Authors: Larin V. , Hmyria V. , Romanovska L. 
Published: September 2023

The article deals with the main aspects of training of higher education applicants in higher military educational institutions and scientific institutions of the Ministry of Defence of Ukraine. The author analyzes the regulatory framework for the acquisition of professional competence of higher education students in higher military educational institutions and scientific institutions of the Ministry of Defence of Ukraine. The national security of Ukraine is an integral part and priority goal of the Ministry of Defence of Ukraine, which accordingly determines the main factors of stable development of society. Russia's full-scale invasion of Ukraine has created the conditions for the emergence of a hybrid form of warfare using the information space, which has forced the creation of new approaches to ensuring and maintaining the national security of the state. In this case, an important role is played by the training of students to acquire competencies in the development and testing of weapons and military equipment, which in today's conditions requires constant updating. Graduates of higher education institutions and research institutions of the Ministry of Defence of Ukraine must take into account the peculiarities of the production of weapons and military equipment in a timely manner in order to ensure the country's defense capability.
The issue of training applicants in the modern conditions of the modern educational process should focus on the ability to make decisions in martial law and uncertainty. The level of education of students will be higher, the broader the chosen field of knowledge, as well as the ability to design solutions in an uncertain situation, which will allow them to have a wider range of possible decision-making methods. Therefore, raising the level of training of students in military sciences will create the preconditions for further implementation of measures that will ensure the development of personnel in the system of higher military education and increase Ukraine's defence capabilities.
Simulating Atomic Dark Matter in Milky Way Analogs

Published: September 2023

Abstract
Dark sector theories naturally lead to multicomponent scenarios for dark matter where a subcomponent can dissipate energy through self-interactions, allowing it to efficiently cool inside galaxies. We present the first cosmological hydrodynamical simulations of Milky Way analogs where the majority of dark matter is collisionless cold dark matter (CDM) but a subcomponent (6%) is strongly dissipative minimal atomic dark matter (ADM). The simulations, implemented in GIZMO and utilizing FIRE-2 galaxy formation physics to model the standard baryonic sector, demonstrate that the addition of even a small fraction of dissipative dark matter can significantly impact galactic evolution despite being consistent with current cosmological constraints. We show that ADM gas with roughly standard model–like masses and couplings can cool to form a rotating “dark disk” with angular momentum closely aligned with the visible stellar disk. The morphology of the disk depends sensitively on the parameters of the ADM model, which affect the cooling rates in the dark sector. The majority of the ADM gas gravitationally collapses into dark “clumps” (regions of black hole or mirror star formation), which form a prominent bulge and a rotating thick disk in the central galaxy. These clumps form early and quickly sink to the inner ∼kiloparsec of the galaxy, affecting the galaxy’s star formation history and present-day baryonic and CDM distributions.

Abstract
This paper reports the first measurement of the relationship between turbulent velocity and cloud size in the diffuse circumgalactic medium (CGM) in typical galaxy halos at redshift z ≈ 0.4–1. Through spectrally resolved absorption profiles of a suite of ionic transitions paired with careful ionization analyses of individual components, cool clumps of size as small as l
cl ∼ 1 pc and density lower than n
H = 10−3 cm−3 are identified in galaxy halos. In addition, comparing the line widths between different elements for kinematically matched components provides robust empirical constraints on the thermal temperature T and the nonthermal motions b
NT, independent of the ionization models. On average, b
NT is found to increase with l
cl following

over three decades in spatial scale from l
cl ≈ 1 pc to l
cl ≈ 1 kpc. Attributing the observed b
NT to turbulent motions internal to the clumps, the best-fit b
NT–l
cl relation shows that the turbulence is consistent with Kolmogorov at <1 kpc with a roughly constant energy transfer rate per unit mass of ϵ ≈ 0.003 cm2 s−3 and a dissipation timescale of ≲100 Myr. No significant difference is found between massive quiescent and star-forming halos in the sample on scales less than 1 kpc. While the inferred ϵ is comparable to what is found in C iv absorbers at high redshift, it is considerably smaller than observed in star-forming gas or in extended line-emitting nebulae around distant quasars. A brief discussion of possible sources to drive the observed turbulence in the cool CGM is presented.

Comparative assessment of retention loss of Locator and OT Equator attachment in implant-supported overdentures: A literature review
Authors: Wani Unmesh S , Jadhav Rajashree , Pol Bhushan , Menge Pritesh , Nair Athira , Bhave Rohan 
Published: September 2023

ABSTRACT
Overdenture is any removable dental prosthesis that covers and rests on one or more remaining natural teeth, the roots of natural teeth, and/or dental implants. A complete removable denture was the conventional therapy for edentulism for decades. Overdentures can be tooth-supported (immediate/traditional) or implant-supported. As the angulation between the implant axis and the path of insertion increased, the retentive forces decreased among the attachments. However, in the Locator (pink) and OT Equator (clear), a stable retentive force was observed up to 30° without a significant difference and decreased at 45°, particularly in the Locator pink. Both systems have acceptable retention capacities. Retention loss depends on the patient’s physiological and systemic conditions. Under the ideal conditions, i.e., when both the attachment caps with similar retentive values, the Locator attachment had shown less retention loss as compared to the OT Equator attachment.
Reconstruction and rehabilitation of atrophic partial edentulous maxillary ridge: Complications and stability
Authors: Durrani Farhan , Imran Fouzia , Jayaprakash Vishnu , Taslim Aabida 
Published: September 2023

ABSTRACT
The esthetics is an essential aspect for an acceptable outcome to a predictable implant therapy. The periodontal disease often destroys the periodontium around the affected teeth. Since the underlying bone act as a scaffold for the soft tissue drape and there is a complex interplay of resorptive events. This establishes the need to meticulously manage tissue deficits, especially in the aesthetic zone. In our report, we describe smile rejuvenation for controlled young periodontitis subject. There was considerable anterior partial ridge atrophy along with severe insufficient gingival volume. Guided bone regeneration was performed to regain the three-dimensional bone volume and mucogingival plastic surgery further corrected the soft tissue architecture around the implant prosthesis. This report highlights the complications associated with reconstruction, rehabilitation, and tissue engineering for partial atrophic ridge in a young subject suffering from controlled periodontitis.

Authors: Suprasanna K , Anand R , Harakuni Sheetal , Ravikiran S R 
Published: September 2023

Abstract

Background
Informed consent has medicolegal implications and is imperative in presentday medical practice.

Aims and Objectives
The objectives of this study were to estimate the awareness regarding informed consent in interns and to determine the effectiveness of sessions in interns’ orientation programs about informed consent.

Materials and Methods
Pretest–Posttest study was conducted with a validated questionnaire distributed through Google Forms to interns attending the orientation program at our institute. Responses were recorded on the Likert scale (−2 to + 2). Paired t-test was used to compare the mean pretest and posttest scores. The number of interns with a positive score (+1, +2) for every question in pretest and posttest were also compared.

Results
One hundred and seventyone out of 232 interns who attended the program submitted both pretest and posttest responses. In the pretest, 12 interns scored < 50% and 46 interns scored more than 75%. A significant increase in posttest responses was seen in the mean score (P < 0.001) and questions related to consent in research, radiological investigations, regarding the need for consent in the additional nonlifesaving procedure. There was an increase in the number of interns having a positive score (+1, +2) for all the questions in posttest as compared to pretest, but a statistically significant increase was seen in questions related to consent in ultrasound and need for consent in the additional nonlifesaving procedure.

Conclusion
A wellstructured interns’ orientation program is effective in improving awareness regarding consent. Certain gaps in knowledge regarding various aspects of consent need to be emphasized.

Abstract

Aims
The purpose of this study was to determine the sex of primary and permanent tooth pulp tissue under different environmental conditions using deoxyribonucleic acid (DNA) analysis and the polymerase chain reaction (PCR) amplification method.

Materials and Methods
For this study, 40 permanent and primary teeth (20 males and 20 females) that were scheduled for extraction were used. For 6 months, the teeth were divided into four groups of ten (5 males and 5 females) based on different environmental conditions. The pulp was extracted from each tooth, DNA was isolated using QIAGEN’s DNeasy Blood and Tissue Kit, and sex was determined using a PCR technique.

Results
DNA was extracted from all 40 samples subjected to various environmental conditions, but sex was correctly determined in only 90% of the samples.

Conclusions
PCR-based sex determination using primary and permanent teeth under different environmental conditions for up to 6 months is a reliable technique with high accuracy.
Genetic Approaches for Sex Determination of Chinese Female with Male Pseudohermaphroditism
Authors: Lai Li , Huang Xiaoli , Zhang Shuning , Wu Yichen , Yang Siyuan , Zhu Zonglin 
Published: September 2023

Abstract
Male pseudohermaphroditism is a rare disorders of sex development (DSD) that is manifested by a female-like appearance or incompletely differentiated external genitalia in an individual with a Y chromosome. In this paper, we report our investigation of the case of a 33-year-old Chinese female who was diagnosed with a malignant mixed germ-cell tumor of the ovary. To confirm the sex of the female, we utilized genetic approaches to detect amelogenin and Y-STR loci. Y chromosome microdeletion was performed to identify existing deletions in the AZF regions and SRY. Chromosome karyotyping and whole-exome sequencing (WES) were then applied to reveal the deletion of sex chromosome segments and pathogenic variations in DNA sequences. Using DNA-STR genotyping, we detected both AMEL-X and AMEL-Y fragments. We also found haplotype Y-STR loci and detected all alleles. Furthermore, no microdeletion was detected in the AZF regions and SRY. The chromosome karyotyping was 46, XY. WES revealed a transversion mutation of 58T → C in the androgen receptor exon 1, which could be the pathogenic variant in this case of abnormal sexual development. Sex determination in forensic DNA typing is based on the amelogenin system. It is important that forensic biologists should master various genetic approaches to overcome the issue of gender ambiguity caused by DSDs.
