Wiman's type inequality for analytic and entire functions and $h$-measure of an exceptional sets
Authors: Skaskiv O.B. , Kuryliak A.O. 
Published: December 2020

Let $\mathcal{E}_R$ be the class of analytic functions $f$ represented by power series of the form $f(z)=\sum\limits\limits_{n=0}^{+\infty}a_n z^n$ with the radius of convergence $R:=R(f)\in(0;+\infty].$ For $r\in [0, R)$ we denote the maximum modulus by $M_f(r)=\max\{|f(z)|\colon$ $ |z|=r\}$ and the maximal term of the series by $\mu_f(r)=\max\{|a_n| r^n\colon n\geq 0\}$. We also denote by $\mathcal{H}_R$, $R\leq +\infty$, the class of continuous positive functions, which increase on $[0;R)$ to $+\infty$, such that $h(r)\geq2$ for all $r\in (0,R)$ and $ \int^R_{r_{0}} h(r) d\ln r =+\infty $ for some $r_0\in(0,R)$. In particular, the following statements are proved.
$1^0.$ If $h\in \mathcal{H}_R$ and $f\in \mathcal{E}_R,$ then for any $\delta>0$ there exist $E(\delta,f,h):=E\subset(0,R)$, $r_0 \in (0,R)$ such that $$ \forall\ r\in (r_0,R)\backslash E\colon\ M_f(r)\leq h(r) \mu_f(r) \big\{\ln h(r)\ln(h(r)\mu_f(r))\big\}^{1/2+\delta}$$ and $$\int\nolimits_E h(r) dr < +\infty. $$
$2^0.$ If we additionally assume that the function $f\in \mathcal{E}_R$ is unbounded, then $$ \ln M_f(r)\leq(1+o(1))\ln (h(r)\mu_f(r)) $$ holds as $r\to R$, $r\notin E$.
Remark, that assertion $1^0$ at $h(r)\equiv \text{const}$ implies the classical Wiman-Valiron theorem for entire functions and at $h(r)\equiv 1/(1-r)$ theorem about the Kövari-type inequality for analytic functions in the unit disc. From statement $2^0$ in the case that $\ln h(r)=o(\ln\mu_f(r))$, $r\to R$, it follows that $ \ln M_f(r)=(1+o(1))\ln \mu_f(r) $ holds as $r\to R$, $r\notin E$.

Published: December 2020

A comparative study of Raman spectra excited by laser radiation λL = 632.8 nm and 488 nm of natural crystals of 2H-MoS2 and nanocrystallites MoS2 (C) containing 0.5 and 1.0 wt.% Carbon additives. A detailed numerical analysis of the shape of observed D and G bands was performed. The complication of the spectra of graphite-like and diamond-like structures with the appearance of additional spectral components at 1440-1500 cm-1 and 1230-1270 cm-1 as a result of doubling the size of the corresponding elementary quasi-cells are analyzed. It is shown that the frequencies of D-bands of diamond-like nanostructures 1297 ÷ 1302 cm-1 don’t depend on λL in contrast to the change in the frequencies of the G (k)-bands. A significant effect of 632.8 nm resonant radiation on the electronic states and properties of MoS2 (C) NC was established. The strengthening of the D bands of the diamond-like structure and the ordering of the graphite structure with increasing carbon content in MoS2 (C) nanocrystals have been established. The change of spectral positions of D, G, and G (k) bands at strengthening the degree of disordering of a diamond- and graphite-like structures is considered. The influence of laser radiation on carbon structures is discussed.

Alloys with the general formula TiCo2-хSn were produced by way of sintering primary components – pure metals in an argon atmosphere. The alloys were homogenized by annealing in the evacuated quartz vessel at T=1070 K during 500 h. X-ray diffraction analysis confirmed single-phase condition of all samples. Nuclear gamma resonance (NGR) analysis was made at T=295 and 80 K using radiation source BaSn119Sn. It was established, that Sn atoms in samples with x=0.6 and 1.0 are in two crystallographic positions, pyramids (1) and tetrahedrons (2) to which isomer shifts correspond (relative to SnO2 1.52-1.65 mm/s for Sn(1) and 2.99 mm/s for Sn(2). Zeeman splitting for Sn(1) in TiCo2Sn takes place at T=295 and 80 K, and for compositions with x=0.3-1.0 at T=80 K only. For Sn(2) it is noted only in alloy TiCoSn at T=80 K. The conclusion has been made on the reason of formation of effective magnetic fields on non-magnetic tin atoms nuclei.

The characteristics of an overstressed bipolar discharge with a duration of 100-150 ns in argon and air, which was ignited between copper electrodes in argon, and also between an aluminum electrode and a chalcopyrite (CuInSe2) electrode in air, are presented. In the process of microexplosions of inhomogeneities on the working surfaces of the electrodes in a strong electric field, the vapor of copper, aluminum, and vapor of ternary chalcopyrite are introduced into the interelectrode gap. This creates the prerequisites for the synthesis of thin copper films and the synthesis of films based on quaternary chalcopyrite - CuAlInSe2, which can be deposited on a quartz plate installed near the center of the discharge gap. The optical characteristics of the plasma, as well as voltage pulses across the discharge gap of d = 1–2 mm, current pulses, and pulsed energy contributions to the discharge, have been investigated using emission spectroscopy with a high time resolution. The plasma emission spectra were thoroughly studied, which made it possible to establish the main decay products of the chalcopyrite molecule and the energy states of atoms and singly charged ions of aluminum, copper, and indium, which are formed in the discharge.

Published: December 2020

This research aims to investigate access to justice for children and women in the Religious Court Decisions after the issuance of Circular Letter of Supreme Court No. 4 of 2016, Point 5 on Religious Chamber. This particular point states that the Religious Court can require a father to provide child maintenance if the child is under the custody of the mother. This is a normative study, with the data obtained from interviews and 150 Religious court decisions. These decisions are issued by the Religious Courts of East Jakarta and Central Jakarta from 2015-2017. The examination of those Decisions reveals that most of the decisions on divorce do not mention any stipulation about child maintenance. This means that the Supreme Court Circular No. 4 of 2016 has not been able to protect children rights in the case of divorce, as well as women’s rights. From the court used in this study, only 14% that require the fathers to provide child maintenance after divorce. This percentage is almost similar to the decisions issued before the issuance of the Circular, which only 12% in 2016, and 14% in 2017. AbstrakPenelitian ini bertujuan untuk mengetahui akses keadilan bagi anak dan perempuan dalam Putusan Pengadilan Agama pasca terbitnya Keputusan Mahkamah Agung Nomor 4 Tahun 2016 Poin 5 tentang Kamar Beragama. Dalam poin khusus ini disebutkan bahwa Pengadilan Agama dapat meminta seorang ayah untuk mengasuh anak jika anak tersebut berada di bawah asuhan ibunya. Penelitian ini bersifat normatif, dengan data diperoleh dari wawancara dan 150 putusan Pengadilan Agama. Putusan-putusan tersebut dikeluarkan oleh Pengadilan Agama Jakarta Timur dan Jakarta Pusat dari tahun 2015- 2017. Berdasarkan pemeriksaan terhadap Putusan tersebut, sebagian besar Putusan perceraian tidak menyebutkan ketentuan tentang pengasuhan anak. Artinya, Surat Edaran Mahkamah Agung Nomor 4 Tahun 2016 belum mampu melindungi hak anak dan hal perempuan dalam kasus perceraian. Data pengadilan yang digunakan dalam penelitian ini, menyebutkan hanya 14% yang mewajibkan ayah untuk mengasuh anak setelah perceraian. Persentase ini hampir sama dengan keputusan yang dikeluarkan sebelum keluarnya keputusan tersebut, yaitu hanya 12% pada 2016, dan 14% pada 2017.

تهدف هذه الدراسة إلى توضيح أحكام موانع النفقة الزوجية في أقوال المذاهب الفقهية الأربعة المعتمدة عند أهل السنة ومذهب الجعفرية ومذهب الإباضية ومقارنتها بقانون الأحوال الشخصية الليبي رقم 10 لسنة 1984 ميلادي وتعديلاته، تحث اسم الأحكام الخاصة بالزواج والطلاق وأثارهما، وقد خصص اختيار هذا القانون لذهابِهِ في تعديله الأول إلى عدم الحديث عن أحكام موانع النفقة الزوجية واكتفي بالحكم في مسألة واحدة منها وهي حق النفقة للمطلقة البائن، بشرط أن لا تختل عقلياً، بل ذهب إلى أبعد من ذلك بإلغائه أحكام النشوز واعتبارها كأن لم تكن، وهي من موانع النفقة، وبقي هذا القانون على حالهِ إلى أن جاء في تعديلهِ الأخير رقم 14 أكتوبر 2015 ميلادي، بحذف مادة أحكام النشوز من الأساس واكتفى بالذكر أنه إذا لم يوجد نص تشريعي يمكن تطبيقه فيها فيحكم بمقتضى المذاهب الفقهية المعتبرة الأكثر ملاءمة لنصوص هذا القانون. Abstrak: Studi ini bertujuan untuk menjelaskan hukum yang menghalangi hak istri atas nafkah dari suami berdasarkan empat mazhab fikih Ahlussunnah wal jama’ah, Ja'fari, dan Ibadhi, yang dibandingkan dengan Hukum Keluarga Islam Libya No. 10 tahun 1984 dan perubahannya, yaitu Peraturan Khusus tentang Perkawinan, Perceraian, dan Dampaknya. Peraturan ini dipilih karena amandemen pertama tidak menyebutkan ketentuan yang menghalangi hak istri untuk mendapatkan nafkah dari suami. Ketentuan yang disebutkan hanya tentang hak pasca cerai dalam hal perceraian ba'in dengan syarat istri memiliki kondisi mental yang sehat. Ketentuan mengenai nushuz dihilangkan meski konsekuensinya menghalangi hak atas nafkah. Dengan demikian, undang-undang tersebut tetap sama hingga amandemen terakhir diberlakukan pada 14 Oktober 2015. Dengan dicabutnya ketentuan nushuz, maka undang-undang tersebut mengikuti ketentuan empat mazhab fikih.

Published: December 2020

This article discusses the relationship between parameters of complete blood count (CBC) and cardiovascular diseases (CVD). The main advantages of CBC over other methods of CVD diagnostics are low cost and wide availability. At the same time, the low specificity of CBC is an important disadvantage, limiting its diagnostic value.After analyzing the results of numerous clinical studies, we concluded that the most important CBC are red cell distribution width, mean platelet volume, total leukocyte count, neutrophil to lymphocyte ratio, platelet-to-lymphocyte ratio, monocyte to high-density lipoprotein ratio. We discuss the diagnostic value of each of the above indicators in CVD. Careful attention to these parameters by clinicians can, to a certain extent, improve the therapeutic and diagnostic process in patients with CVD.

Aim. To determine the predictive role of estimated pulmonary artery systolic pressure (ePASP) in COVID-19 patients.Material and methods. A retrospective study of inpatients with documented COVID-19 infection was carried out. Maximal follow-up period was 63 days. The study included 108 patients (men, 62; women, 46; mean age, 62,9±15,5 years). At admission, mean NEWS score was 6,0, blood oxygen saturation — 92%. Echocardiography was performed according to standard protocol using Vivid E9 ultrasound system (GE Healthcare). Quantitative measurements were performed according to the current ASE and EACVI guidelines. Statistical analysis was performed using the IBM SPSS Statistics v.26 software (developed by IBM Corporation).Results.Using the CHAID technique, a classification tree was developed and the strongest predictor of an unfavorable outcome was determined (ePASP). Threshold ePASP values, associated with an increased mortality risk were established (42 mm Hg and 50 mm Hg). Three groups of patients were selected based on the main predictor (<41,0 mm Hg, 42-49 mm Hg and >50 mm Hg). The increased mortality risk was noted in groups 2 and 3 compared to group 1 of patients and amounted to 31,8% and 70% versus 3,9%, respectively. There was also a correlation between the severity of CT lung parenchymal lesions according to computed tomography and the study groups of patients (36% [30-49%] — group 1, 50% [36-76%] — group 2, and 84% [56-92%] — group 3, p=0,001). In groups 2 and 3, the following complications were significantly more frequent: acute respiratory distress syndrome, acute heart failure, multiple organ system failure, venous thrombosis, disseminated intravascular coagulation. In group 3, acute renal failure and systemic inflammatory response syndrome developed significantly more often than in group 1.Conclusion.A comprehensive echocardiography has proven its availability and safety in assessing the condition of COVID-19 patients, allowing to obtain relevant information on pulmonary hemodynamics. Transthoracic echocardiography reduced the risk of complications from invasive diagnostic methods and allowed to abandon the use of the Swan-Ganz pulmonary artery catheter in the studied group of patients. As a result, a relationship was noted between the increase of ePASP and the severity of clinical performance and lung tissue damage according to computed tomography, changes in laboratory blood tests, the severity of the comorbid profile, an increase in respiratory support need.

One of the tasks of population-based biobanks is to determine the frequencies of clinically relevant genetic polymorphisms in the population. The population of Russia is very heterogeneous both ethnically and genetically. Therefore, the frequencies of genetic markers are in demand not in one sample, but in a series of samples reflecting the heterogeneity of the gene pool of different peoples and regions.Aim. To divide the population of Russia and neighboring countries into population groups meeting certain conditions, as well as having a representative sample in existing data and biobanks.Material and methods. We developed a method for combining populations into larger groups with maintaining intragroup homogeneity based on the principal components analysis with K-means clustering, followed by refinement of clustering for higher homogeneity and a more equal distribution of group sizes using FST distances. The technology has been adjusted using the example of the Biobank of Northern Eurasia. Therefore, the material was the genome-wide data on 4.5 million genetic markers for 1,883 samples representing 247 populations of Russia and neighboring countries from this biobank. The developed approach, the resulting set of populations and related map can be applied for other collections of biomaterials from Russian populations.Results. Application of this approach made it possible to divide the entire population of Russia and neighboring countries into 29 ethnogeographic groups, characterized by relative genetic homogeneity. This set of populations is recommended as a baseline for population screenings to identify the frequency of any genetic markers among the population of Russia. A map has been constructed showing the division of population into 29 ethnogeographic areas.Conclusion. On the basis of a reliable genome-wide data, the zoning of gene pool of the Russian population was carried out. We identified ethnogeographic groups with intergroup contrasting allele frequencies, but at the same time with relatively homogeneous intragroup parameters. The resulting map and register of groups can be used in population genetic, medical genetic and pharmacogenetic studies.

A Comparative Analysis of Resilience of Islamic and Conventional Banks in Indonesia
Authors: Ulina Sri , Majid M. Shabri Abd. 
Published: December 2020

The presence of the 2008 Global Financial Crisis (GFC) has adversely impacted both conventional and Islamic banking performances. This study aims to empirically compare the ﬁnancial performances between Islamic banks and conventional banks during the pre- and post-2008 GFC periods. It also attempts to compare the ﬁnancial performance of each Islamic and conventional bank between the pre- and post-2008 GFC periods. Three state-owned banks from each conventional and Islamic banking category were selected as the study sample using the purposive sampling technique. Based on the independent sample t-test, the study found a signiﬁcant diﬀerence between the Islamic and conventional banking performances during the pre- and post-2008 GFC periods. Meanwhile, based on the paired t-test, the decline in Islamic banking performance from the pre-2008 GFC to the post-2008 GFC periods was signiﬁcantly smaller than their conventional banking counterparts. These ﬁndings show the Islamic banks' superiority over their conventional banking counterparts due to fair and just practices based on Islamic tenets. Due to theirreliance in facing the episodes of crises, the Islamic banks deserve a strong support by government by enhancing prudent Islamic banking regulation. The Islamic banks should strive to operate fully based on the shari'ah principles and prudent banking management.
