Published: July 2024

В статье реализована эмпирическая апробация логического подхода к управлению портфелем финансовых активов с фиксированным доходом на примере облигаций. Логический подход к управлению, его теоретическая сущность и методические аспекты реализации были предложены автором в серии статей, опубликованных ранее. В статье предложены пошаговые методические рекомендации по реализации логического подхода к управлению. На рыночных данных по выборке из широкого массива облигаций российского долгового рынка, эмитентов из разных отраслей и секторов экономики, была проведена апробация подхода и оценка его эффективности. Результаты моделирования позволили сделать вывод, что эффективность модельного портфеля превышает эффективность обращающихся на российском рынке инвестиционных фондов, ориентированных на инвестиции в облигации в плоскости риск-доходность. Автором также показано, что предлагаемый логический подход имеет ряд преимуществ по сравнению с традиционными подходами к управлению. Логический подход является универсальным и позволяет строить портфель на любых видах облигаций, включать неограниченный перечень факторов для их оценки и осуществлять простое управление портфелем в будущем.
The article realizes the empirical testing of the logical approach to managing a portfolio of financial assets with fixed income on the example of bonds. The logical approach to management, its theoretical essence and methodological aspects of implementation were proposed by the author in a series of articles published earlier. The article offers step-by-step methodological recommendations for the realization of the logical approach to management. On market data on a sample of a wide array of bonds of the Russian debt market, issuers from different industries and sectors of the economy, the approach was tested and its effectiveness was assessed. The results of modeling allowed us to conclude that the efficiency of the model portfolio exceeds the efficiency of investment funds circulating in the Russian market, focused on bond investments in the risk-return plane. The author also shows that the proposed logical approach has a number of advantages over traditional approaches to management. The logical approach is universal and allows building a portfolio on any types of bonds, including an unlimited list of factors for their evaluation and carrying out simple portfolio management in the future.

Cockroaches are the greatest potential mechanical vector of various pathogenic microorganisms, some of which cause serious diseases in humans and domestic animals. The high prevalence of human pathogens carried by the cockroach has been reported in many countries. This study aimed to determine the prevalence of internal and external parasites parasitizing the American cockroach, Periplaneta americana, the effect of the sex of the cockroach and the area of sample collection on The type, number and types of parasites isolated, The current study was conducted for the period from July 2023 until April 2024, A samples of 111 male Periplaneta americana cockroaches were collected from some homes and schools in the city of Mosul. After the samples arrived at the laboratory, by placing them in clean, sterilized tubes in a refrigerator set at -4°C for 10 minutes Subsequently, 10 ml of normal saline solution was added to each tube. The tubes were then vigorously shaken for 5 minutes to dislodge parasites a salt solution was added to centrifuge tubes, which were spun at 2000 rotations per minute for 5 minutes. This mixture was shaken for 5 minutes and then, Cockroaches were dissected to isolate internal parasites The contents of the digestive tract were taken, and the solution was filtered through a mesh. Each sample was prepared by placing a drop of sediment on a glass slide, adding Lugol's iodine dye, and examining it under a microscope. The majority of the samples were infected with one or more types of parasites on their body surfaces and within their digestive tracts, infection rate of 96.40 %. This study involved the isolation and diagnosis of 19 parasitic species, including five types of worms: Ancylostoma duodenale, Leidynema, Strongyloides stercoralis, Hammerschmidtiella male, and Thelastoma. and six types of protozoan parasites, including both active and Nyctotherus ovalis cyst, active and cyst stages of Lophmonas, cyst stage of Entamoeba coli, and Gregarine. and Seven types of eggs, comprising eggs of each of Ancylostoma duodenale, Thelastoma, Leidynema, Strongyloides stercoralis, Hammerschmidtiella , Gryllophila, and in addition to the external parasitic Mite, The highest infection rate was recorded in worms, with 91 out of 111 samples i.e. (81.98% ). This was followed by protozoa, with a rate of 72% out of 80 samples. Finally, external mites, 52 samples i.e. (46.84%). In this study, it was observed that the number of parasites harbored by cockroaches in their digestive tracts exceeds more than that found on their external surfaces. Cockroaches collected from households were found to harbor a greater number of parasites compared to those collected from schools, underscoring the necessity of raising awareness about the dangers of cockroach presence in homes and keeping them away from food sources due to the parasites they carry, which may cause various diseases.
Probing Velocity Dispersion Inside Coronal Mass Ejections: New Insights on Their Initiation

Abstract
This work studies the kinematics of the leading edge and the core of six coronal mass ejections (CMEs) in the combined field of view of Sun Watcher using Active Pixel System detector and Image Processing (SWAP) on board PRoject for On-Board Autonomy (PROBA-2) and the ground-based K-Cor coronagraph of the Mauna Loa Solar Observatory. We report, for the first time, on the existence of a critical height hc
, which marks the onset of velocity dispersion inside the CME. This height for the studied events lies between 1.4 and 1.8 R
⊙, in the inner corona. We find the critical heights to be relatively higher for gradual CMEs, as compared to impulsive ones, indicating that the early initiation of these two classes might be different physically. We find several interesting imprints of the velocity dispersion on CME kinematics. The critical height is strongly correlated with the flux-rope minor radius and the mass of the CME. Also, the magnitude of the velocity dispersion shows a reasonable positive correlation with the above two parameters. We believe these results will advance our understanding of CME initiation mechanisms and will help provide improved constraints on CME initiation models.

Abstract
Mrk 501 is a prototypical high-synchrotron-peaked blazar and serves as one of the primary targets for the Imaging X-ray Polarimetry Explorer (IXPE). In this study, we report X-ray polarization measurements of Mrk 501 based on six IXPE observations. The detection of X-ray polarization at a confidence level exceeding 99% is achieved in four out of the six observations conducted across the entire energy range (2–8 keV) of IXPE. The maximum polarization degree (ΠX) is measured to be 15.8% ± 2.8%, accompanied by a polarization angle (ψ
X) of 98.°0 ± 5.°1 at a confidence level of 5.6σ. During the remaining two observations, only an upper limit of ΠX < 12% could be derived at the 99% confidence level. No temporal variability in polarization is observed throughout all six IXPE observations for Mrk 501. A discernible trend of energy-dependent variation in the polarization degree is detected in optical spectropolarimetry; however, no analogous indication is observed in ΠX. The chromatic behavior of Π and the consistent values of ψ across different frequencies from X-ray to radio bands, along with the agreement between ψ and jet position angle, strongly support the interpretation of the energy-stratified model with shock-accelerated particles in the jet of Mrk 501. Additionally, the possibility of the presence of a global helical magnetic field in the jet of Mrk 501 is discussed.
La plaque commémorative : l’histoire au défi du format contraint
Authors: Largier Vié Céline 
Published: July 2024

Cet article a pour objet les plaques commémoratives relatives à la Seconde Guerre mondiale à Paris, envisagées sous l’angle du format. Ce dernier peut être envisagé dans sa dimension matérielle. Mais il peut également être envisagé comme format d’écriture, c’est-à-dire comme agencement scriptural découlant de conventions textuelles. Enfin, la question du format peut être envisagée sous l’angle du formatage, qui interroge ce que peuvent être les contraintes institutionnelles. Tenant compte de ces trois approches, l’objectif sera de répondre à plusieurs questions : quelles sont les caractéristiques matérielles de ces plaques ? Le texte qu’elles portent s’inscrit-il dans un format d’écriture contraignant ? Les plaques sont-elles le résultat d’un formatage ou une marge de liberté est-elle accordée à leurs promoteurs ?
