Published: December 2022

The objective of the research is to carry out a review of the literature about suicide risk factors in young university students. The methodology used is quantitative descriptive with a bibliometric approach, under the PRISMA method. The search was carried out in three databases: Clarivate Web of Science, MDPI and Taylor and Francis that had the variables of suicide risk factors. Inclusion criteria were used such as: study variables, years 2019 to 2022, published in Spanish and English,scientific reports research results, research with clinical and non-clinical population. After the application of the Boolean operators, the total sample is (n=10360) and after screening with the PRISMA method (n=45). Results: The United States, followed by China and Bangladesh, are the countries that produce the most on the subject. The most frequent risk factors are: depression, anxiety, stress, academic commitments, lack of opportunities, low income and race. The students with the highest suicide rates are in the health area such as medicine and nursing, in addition, there is more suicide intent in women than in men.

Es por ello que, la finalidad de este articulo es informar los estándares internacionales en el derecho a la salud
El Fundraising: una reflexión sobre una disciplina en continuo ascenso
Authors: Anzuini Francesco
Published: December 2022

Donar es una tradición antigua, que tiene que ver inicialmente con la caridad cristiana, el desarrollo de las sociedades de ayuda mutua en Italia y las cajas de las corporaciones. En tiempos más cercanos, son las ONG internacionales y nacionales las encargadas en representar la cultura del dono, la cual ha tenido y sigue teniendo un rol fundamental en la sociedad civil, ya que no siempre ha sido reconocida como se merece.

El tentativo de dar una estructura formal a la cultura del dono es el Fundraising, la cual es la práctica de administración que se utiliza para sostener organizaciones sin fin de lucro, demostrando especialmente en la emergencia por la crisis mundial causada desde la pandemia de Covid-19, como a través de la generosidad y con una comunicación transparente, se puede de verdad cambiar la vida de las personas creando una relación que va más allá de la recaudación de fondos.

El fenómeno del Fundraising tiene en si una estela de efectos extremamente positivos. De hecho, esta disciplina, todavía poco enseñada a nivel formal y vista como una práctica artesanal de administración y marketing, tiene en sí, numerosas conexiones con otras disciplinas, a través el uso de prácticas extremamente innovadoras.

El fundraising ha pasado desde el ser una herramienta implícita a otras actividades en las organizaciones solidarias y sin fin de lucro, a herramienta secundaria, a veces accesoria a actividad profesional que mueve millones de dólares solo en los Estados Unidos de América y Italia.

Peripheral nerve injuries in the mother and newborn during delivery represent two obstetrical challenges, for which we try to find the best results both from the point of view of diagnosis and therapeutic strategy. The mother’s lesions can be due to obstetric trauma and neuraxial anesthesia, while fetal injuries are mainly caused by obstetric trauma due to instrumental vaginal delivery but also secondary to abnormal presentations, macrosomia, and deficiencies regarding perinatal monitoring during spontaneous vaginal birth. In most cases, these lesions resolve spontaneously, or if they persist, conservative treatment or surgical correction is necessary. Peripheral nerve injuries in the mother and the newborn continue to remain a challenge addressed to obstetricians and neonatologists, as in-depth, randomized studies are needed to develop clinical guidelines that can be applied.

About 3-5% of pregnancies are complicated by preeclampsia (PE), a multisystem disorder of exact unknown etiology, characterized by new-onset hypertension (>140/90 mmHg), proteinuria, and/or evidence of organ dysfunction. Although it is not yet completely understood what causes PE, maternal and placental factors seem to be involved. Endothelial dysfunction, maternal vascular inflammation, and remodeling of spiral arteries during placentation seem to be the underlying mechanisms of this pregnancy-related disease. Acute PE neurological complications, such as eclamptic seizures, cerebral edema, and intracerebral hemorrhage, are responsible for more than 70% of maternal deaths. Furthermore, long-term complications, such as cognitive dysfunction, the elevated lifetime risk of cerebrovascular disease, and persistent white matter lesions increase the rate of PE-related maternal morbidity and mortality. Hypertensive disorders associated with pregnancy affect not only the mother but also the baby by restricting the supply of nutrients and oxygen to the fetus. This has been associated with impaired cognitive development in children, increased lifetime cerebrovascular, cardiovascular, and metabolic risk, low intelligence quotient (IQ) and mental development indices (MDI), and more depression symptoms later in life. This study aims to review the literature and synthesize available information about preeclampsia and its neurological consequences on both the mother and the fetus.

Zika virus is a flavivirus transmitted mainly by Aedes mosquitoes, and pregnant women are usually asymptomatic or have non-specific symptoms. The virus can cross the placental barrier and is intensely neurotropic, with destructive and malformative consequences on the fetal central nervous system, causing a series of severe abnormalities in infected fetuses in the first trimester, more severe than in TORCH infections. Viral infection can be suspected during ultrasound screening by highlighting severe microcephaly and macroscopic calcifications in the fetal brain. In addition, auditory, ocular, or musculoskeletal abnormalities have been reported. Prophylaxis of infection in pregnant women is essential due to the increased risk of fetal damage currently, there is no vaccine or approved treatment.

Premature birth is an important public health problem associated with increased perinatal morbidity and mortality rates. Due to the triggering mechanisms of premature birth as well as the immaturity of the fetal brain, it is more prone to injury. Thus, these premature babies have an increased risk of immediate neurological complications as well as late neurodevelopmental abnormalities, which can have lifelong repercussions. Prompt identification of fetal brain injury and their treatment, as well as the supervision at regular time intervals of the neurodevelopment of children born prematurely, are a real challenge for the medical system.
GÖÇMEN ÇOCUKLARIN EDEBİYATI: ÖTEKİ KAVRAMININ İZİNDE ALMANYA VE BULGARİSTAN ÖRNEĞİNDE ÇOCUK KİTAPLARINA GENEL BİR BAKIŞ
Authors: Tuna Sibel , Asutay Hikmet
Published: December 2022

Öteki kavramı yazın dünyasında yirminci yüzyılın ikinci yarısında çokça kullanılmaya başlanmış bir kavram olagelmiş ve günümüzde de artan küreselleşme süreciyle birlikte daha fazla gündem olmaya başlamıştır. Yazınbilim içinde de öteki kavramı ile birlikte ötekileştirilen daha alt yazın türleri söz konusu olmaya başlamıştır. Bunlardan biri azınlık yazınıdır. Bu çalışmada ele alınan Bulgaristan Türklerinin yazını bu anlamda öteki yazın olarak görülmüştür. Bir diğer alt tür olan çocuk ve gençlik yazını da uzun zamanlar boyunca öteki yazın ya da bir alt yazın olarak ifade edilmiştir. Bu çalışmada her iki öteki olarak görülen alt yazın örneklerinin bir araya geldiği Bulgaristan’daki Türk Çocuk yazını ele alınmıştır. Türk nüfusunun Türkiye dışında yoğun olarak yaşadığı ülkelerin başında Almanya ve Bulgaristan gelmektedir. Çocuk Edebiyatı ise son zamanlarda adından sıkça söz ettiren yeni bir disiplin olarak karşımıza çıkmaktadır. Çalışma ile Almanya ve Bulgaristan örneğinde, çocuk edebiyatı bağlamında Türk yazarlar ve şairler tarafından üretilmiş olan çocuk kitaplarının genel olarak tanıtılması amaçlanmaktadır. Bu çalışmanın örneklemini random olarak seçilen 50 tane Almanya’da yayınlanmış olan çocuk kitapları ile 50 tane Bulgaristan’da yayınlanmış olan çocuk kitaplarından oluşmaktadır. Çalışmaya her iki ülke örneğinde, çevirisi yapılan kitaplar ile Türkiye’ye göç eden Türk yazar ve şairlerinde bu alandaki kitapları dâhil edilmiştir. Ana vatandan ayrı olarak varlığını sürdüren Türkler için yeni nesillere gerek Türk dilinin öğretilmesi gerekse kültür aktarımının sağlanması açısından çocuk kitapları önemli bir görev üstlenmektedirler. Öteki kavramının izlerinin çocuk kitaplarında da sürülebilmesi açısından da ayrı bir öneme sahiptirler. Bu nedenle çalışmanın bir bölümünü Almanya’da yaşayan Türk yazar ve şairler tarafından yazılan çocuk kitapları diğer bölümünü de Bulgaristan’da yaşayan Türk yazar ve şairler tarafından üretilmiş çocuk kitapları oluşturmaktadır.
PEYAMİ SAFA’NIN ESERLERİNDE “BİZ” VE “ÖTEKİ” KAVRAMLARINA KARŞILAŞTIRMALI BİR BAKIŞ
Authors: Angın Zeynep
Published: December 2022

Bu çalışmada Peyami Safa’nın incelenmek üzere seçilmiş olan Sözde Kızlar, Mahşer ve Fatih-Harbiye adlı eserleri, “biz” ve “öteki” kavramları bağlamında değerlendirilmeye çalışılacaktır. Buradaki amaç, eserlerdeki iki kutbu oluşturan bu kavramların neyi temsil ettiğinin belirtilmesi ve aralarındaki benzerlik ve farklılıkların yazarın üslubu, dünya ve edebi görüşünü nasıl yansıttığını karşılaştırmalı bir bakış ile irdelemektir. Peyami Safa’nın eserlerine bakıldığında, yazarın doğu-batı anlayışını ve alaturka ile alafranga; eski ile yeni ve hatta iyi ile kötüyü okura iletmek için “biz” ve “öteki” kavramlarını sıklıkla kullanılmış olduğu görülür. Yazarın kullandığı “biz”in karşılığı Türkler, Müslümanlar ve Doğu’dur; “öteki”nin karşılığı ise Avrupalılar, Batı ve Avrupalılara özenip kendi kimliklerini unutan Türklerdir. Bu noktada yazarın o dönemki Türk toplumunda yer alan Avrupa hayranı, batılılaşmayı yanlış yorumlayan Türklere karşı takındığı tavır da açıktır. Esasında Tanzimat Dönemi Edebiyatı’nda ilk örnekleri verilen Batılı anlamda roman örneklerinde yanlış batılılaşma ve onun yarattığı ikilemler sıklıkla kullanılan bir temadır. Bu nedenle o dönem romanlarının kurgularında batı hayranı züppe tip ile kendi değerlerini temsil eden daha mütevazı tipler hep karşı karşıya getirilir ve bu iki tip arasında tereddüt yaşayan kadın karakterler, yaşadıkları tereddüdün buhranlarının ardından alaturka olan tarafı seçer. İncelenecek olan eserlerin kurgularında bu tarz belirgin bir “biz” ve “öteki” kutbu dikkati çekmektedir. Özellikle “öteki” kavramı Peyami Safa tarafında okura doğru yolu göstermek ve yanlış tarafı temsil eden tiplerin acınası hallerini anlatmak amacıyla kullanılmaktadır.
MEMURUN ÖLÜMÜ ve UĞURSUZLUK HİKÂYELERİ ÜZERİNE İKİLİ BİR OKUMA
Authors: Akdeniz Safiye
Published: December 2022

Cumhuriyet döneminin önemli hikâye yazarlarından Memduh Şevket Esendal aynı zamanda önemli bir diplomat ve siyaset adamıdır. 1920-1924 yılları arasında Bakü’de ortaelçi olarak görev yapar. Bu görevi sırasında Rusça öğrenir ve Rus edebiyatını takip eder. Memduh Şevket’in etkilendiği sanatçıların başında Çehov gelmektedir. Durum hikâyesinin yaratıcısı olan Çehov sadece Memduh Şevket için değil tüm dünya edebiyatçıları için önemli bir ilham kaynağıdır. Memduh Şevket’in hikâyeleri incelendiğinde birçok bakımdan Çehov’un izlerine rastlamak mümkündür. Ancak Memduh Şevket durum hikâyesini benimsemekle birlikte hikâyelerine kendi dünya görüşü ve bakış açısını yansıtmayı, içinde yaşadığı toplumun olayları ve insanlarını ustalıklı bir biçimde işlemeyi başarır.
Bu çalışmada Çehov’un Memurun Ölümü başlıklı hikâyesiyle Memduh Şevket’in Uğursuzluk başlıklı hikâyeleri karşılaştırmalı olarak incelenmektedir. Konu ve konunun işlenişi bakımından iki metin arasındaki benzerlikler ve farklılıklar tespit edilmeye çalışılmaktadır. İki hikâye arasındaki temel farklılık sonuç kısmında görülür. Çehov, başkahramanına karşı eleştirel ve acımasızdır. Hikâye başkahramanın ölümüyle sonlanır. Oysaki Memduh Şevket baştan itibaren kahramanına karşı şefkatli, merhametli ve tahammüllüdür. Bu sanatçının iyiliği ve umudu yaşam felsefesi edinmiş olmasıyla yakından ilişkilidir. Küçük bir memur olan ve dünyası da oldukça küçük olan Hayri Efendi’ye yaşam hakkı tanınması yazarın bakış açısını metnin içeriğine taşımanın yanı sıra metine- Çehov’un hikâyesine göre- daha realist bir nitelik kazandırır. Bunu dışında iki metin birçok açıdan benzerlik gösterir: Olayların küçük memurların üstleriyle olan ilişkilerini işlemesi, memuriyetteki hiyerarşik düzenin ve yaşam şartlarının insan davranışları üzerindeki etkisi, devlet dairelerinin işleyişi gibi. Yazarların içinde yaşadıkları toplumun insanını ve olaylarını konu edinerek belli bir döneme tanıklık etmeleri, benzer bir kurgu ve anlatım tekniklerinden faydalanmaları ise dikkat çeken diğer benzerliklerdir.

We present analyses of improved photometric and spectroscopic observations for two detached eclipsing binaries at the turnoff of the open cluster NGC 752: the 1.01 days binary DS And and the 15.53 days BD +37 410. For DS And, we find M
1 = 1.692 ± 0.004 ± 0.010M
⊙, R
1 = 2.185 ± 0.004 ± 0.008R
⊙, M
2 = 1.184 ± 0.001 ± 0.003M
⊙, and R
2 = 1.200 ± 0.003 ± 0.005R
⊙. We either confirm or newly identify unusual characteristics of both stars in the binary: the primary star is found to be slightly hotter than the main-sequence turnoff and there is a more substantial discrepancy in its luminosity compared to models (model luminosities are too large by about 40%), while the secondary star is oversized and cooler compared to other main-sequence stars in the same cluster. The evidence points to nonstandard evolution for both stars, but most plausible paths cannot explain the low luminosity of the primary star. BD +37 410 only has one eclipse per cycle, but extensive spectroscopic observations and the Transiting Exoplanet Survey Satellite light curve constrain the stellar masses well: M
1 = 1.717 ± 0.011M
⊙ and M
2 = 1.175 ± 0.005M
⊙. The radius of the main-sequence primary star near 2.9R
⊙ definitively requires large convective core overshooting (>0.2 pressure scale heights) in models for its mass, and multiple lines of evidence point toward an age of 1.61 ± 0.03 ± 0.05 Gyr (statistical and systematic uncertainties). Because NGC 752 is currently undergoing the transition from nondegenerate to degenerate He ignition of its red clump stars, BD +37 410 A directly constrains the star mass where this transition occurs.
Formation and Reconnection of Electron Scale Current Layers in the Turbulent Outflows of a Primary Reconnection Site
Authors: Lapenta Giovanni , Goldman Martin , Newman David L. , Eriksson Stefan
Published: December 2022

We simulate with 3D particle in cell, the spontaneous formation of turbulent outflows in an initially laminar 3D reconnecting current layer. We observe the formation of many secondary current layers and reconnection sites in the outflow. The approach we follow is to study each individual feature within the turbulent outflow. To identify all clusters of current in the outflow we use a clustering technique widely used in unsupervised machine learning: density-based spatial clustering of applications with noise. Once the clusters are identified we measure their size and compute reconnection indicators to establish which are undergoing reconnection. With this analysis we establish that the size of the current clusters reaches all the way from its initial system scale down to subelectron skin depth scale. We observe that the smaller current clusters are more prone to reconnecting and to releasing energy. We then find the process of reconnection of the smaller current cluster to be of the recently observed electron-only type that leaves the ions essentially unaffected.
Interpretation of Radio Wave Scintillation Observed through LOFAR Radio Telescopes

Published: December 2022

Radio waves propagating through a medium containing irregularities in the spatial distribution of the electron density develop fluctuations in their intensities and phases. In the case of radio waves emitted from astronomical objects, they propagate through electron density irregularities in the interstellar medium, the interplanetary medium, and Earth’s ionosphere. The LOFAR radio telescope, with stations across Europe, can measure intensity across the VHF radio band and thus intensity scintillation on the signals received from compact astronomical objects. Modeling intensity scintillation allows the estimate of various parameters of the propagation medium, for example, its drift velocity and its turbulent power spectrum. However, these estimates are based on the assumptions of ergodicity of the observed intensity fluctuations and, typically, of weak scattering. A case study of single-station LOFAR observations of the strong astronomical source Cassiopeia A in the VHF range is utilized to illustrate deviations from ergodicity, as well as the presence of both weak and strong scattering. Here it is demonstrated how these aspects can lead to misleading estimates of the propagation medium properties, for example, in the solar wind. This analysis provides a method to model errors in these estimates, which can be used in the characterization of both the interplanetary medium and Earth’s ionosphere. Although the discussion is limited to the case of the interplanetary medium and Earth’s ionosphere, its ideas are also applicable to the case of the interstellar medium.
R-matrix Electron-impact Excitation Data for the H- and He-like Ions with Z = 6−30

Published: December 2022

Plasma models built on extensive atomic data are essential to interpreting observed cosmic spectra. H-like Lyman series and He-like triplets observable in the X-ray band are powerful diagnostic lines to measure the physical properties of various types of astrophysical plasmas. Electron-impact excitation is a fundamental atomic process for the formation of H-like and He-like key diagnostic lines. Electron-impact excitation data adopted by the widely used plasma codes (AtomDB, CHIANTI, and SPEX) do not necessarily agree with each other. Here we present a systematic calculation of electron-impact excitation data of H-like and He-like ions with the atomic number Z = 6–30 (i.e., C to Zn). A radiation-damped R-matrix intermediate-coupling frame transformation calculation was performed for each ion with configurations up to n = 6. We compare the present work with the above three plasma codes and the literature to assess the quality of the new data, which are relevant for current and future high-resolution X-ray spectrometers.
Failed Solar Eruption of a Multithermal Flux Rope
Authors: Li Leping , Song Hongqiang , Peter Hardi , Chitta Lakshmi Pradeep
Published: December 2022

A magnetic flux rope (FR), hosting hot plasma, is thought to be central to the physics of coronal mass ejections. Such FRs are widely observed with passbands of the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory that are sensitive to emission from the hot plasma around 10 MK. In contrast, observations of warmer (around 1 MK) counterparts of FRs are sparse. In this study, we report the failed eruption of a multithermal FR, hosting both hot and warm plasma. On 2015 May 1, a hot channel appeared in the AIA high-temperature passbands out of the southeastern solar limb to the south of a nearby flare, and then erupted outward. During the eruption, it rotated perpendicular to the erupting direction. The hot channel stopped erupting, and disappeared gradually, showing a failed eruption. During the hot channel eruption, a warm channel appeared sequentially in the AIA low-temperature passbands. It underwent a similar evolution, including the failed eruption, rotation, and disappearance, to the hot channel. A bright compression front is formed in front of the warm channel eruption in AIA low-temperature images. Under the hot and warm channel eruptions, a small flare occurred, upon which several current sheets, connecting the erupting channels and the underneath flare, formed in the AIA high-temperature passbands. Investigating the spatial and temporal relation between the hot and warm channels, we suggest that both channels twist together, constituting the same multithermal FR that has plasma with the high and low temperatures.
A Partial Disintegration of Active Centaur/Comet P/2020 MK4?
Authors: Romanishin W. , Tegler S. C.
Published: December 2022

Centaur P/2020 MK4 (a = 6.19 au, e = 0.011) was discovered in 2020 and quickly brightened to V ∼ 18.5. As of early 2022 November, no astrometric observations had been reported in 2021 or 2022. The object should have been easily found had it retained its 2020 absolute magnitude. We find that P/2020 MK4 now appears as an ∼10″ wide low surface brightness coma, with a faint (r ∼ 24.9) point-like source. The rates of brightening and fading of P/2020 MK4 are both much slower than the larger Centaur 29P/Schwassmann-Wachmann 1, which is on a similar orbit. Perhaps the image morphology and unusual brightening and fading of P/2020 MK4 were due to a partial disintegration event.

Published: December 2022

Broadband receiver data need color corrections applying to correct for the different source spectra across their wide bandwidths. The full integration over a receiver bandpass may be computationally expensive and redundant when repeated many times. Color corrections can be applied, however, using a simple quadratic fit based on the full integration instead. Here we describe fastcc and interpcc, quick Python and IDL codes that return, respectively, color correction coefficients for different power-law spectral indices and modified blackbodies for various Cosmic Microwave Background related experiments. The codes are publicly available, and can be easily extended to support additional telescopes.

Authors: Prakoeswa Cita Rosita Sigit , Hidayah Nur , Dewi Arlina
Published: December 2022

Background: Customer loyalty is identified as a critical component of a company's success and profitability including in hospitals. Customer loyalty can only be accomplished if the company can provide high-quality services. The purpose of this study was to understand the influence or factors behind patient loyalty. Methods: Systematic literature review methods were used to process articles found in various journals and databases such as Elsevier, NCBI, Lancet, Springer, Nature, Taylor and Francis, ProQuest, Emerald, JSTOR, Web of Science, and GARUDA SINTA (the Science and Technology Index of expertise in Indonesia).  Results: The initial search resulted in 1.174 (1 duplicated) and 1.173 were screened based on title and abstract. Finally, 29 articles were included for review regarding inclusion and exclusion criteria. The finding shows that concern for medical staff, perceived value, price, trust, treatment effectiveness, Service Quality, Interaction, Infrastructure, Process, and brand image, consequently affect patient satisfaction and loyalty. Those factors as an intervening variable in patient loyalty. Conclusion: In general, hospital health workers' competency, tangible factors (facilities), communication, punctuality in work (responsiveness), patient waiting time (facility satisfaction and responsiveness), queuing system, drug availability (price factor, facility satisfaction), providing information to clients (trust and communication, guarantees), equal treatment for uninsured patients, and complaint system for clients (Hospital Image) impact patient loyalty directly or indirectly.

Published: December 2022

BACKGROUND: The difficult epidemiological situation of COVID‒19 infection in the world and in the country requires drastic measures to strengthen the material, technical, and staffing of health-care provision in the obstetrics and gynecology practices. It has also created an environment conducive to innovation and the accelerated implementation of new ideas. This is an attempt to discuss the potential implications for obstetrics and gynecologic practice in the world.

AIM: This study review gives a comprehensive overview on the effects of the COVID-19 pandemic of the potential implications for obstetrics and gynecologic practice.

METHODS: The data-based used in the source search were MEDLINE and PubMed databases using terms such as: COVID-19/SARS-CoV-2, impact of corona virus on the health sector and COVID-19 in obstetrics and gynecology care. We searched several databases for English articles published between January 2020 and February 2022 that discussed or touched on the effects the pandemic had of the potential implications for obstetrics and gynecologic practice in OECD countries.

RESULTS: In total, eight relevant articles discuss the relationship between reorganization of the practice of obstetrics and gynecology and other challenges that placed health-care providers under considerable psychological stress. Some studies showed that the discussed extensively the potential implications of COVID-19 for obstetrics and gynecologic practice.

CONCLUSION: Successful coping strategies have been adapted to local conditions and the working conditions of staff and, most importantly, patients, so we recommend turning these temporary strategies into permanent solutions that can be quickly applied during future pandemics.

The studies mostly used chitosan combined with other biomaterials such as demineralized bone matrix (DBM), genipin (GP), sodium alginate (SA), resveratrol (Res), polycaprolactone (PCL) and collagen, growth factor and stem cells such as bone morphogenic protein-2 (BMP-2), dental pulp stem cell (DPSC), and human umbilical cord mesenchymal stem cells (hUCMSC).
Conclusion: Chitosan is a natural polymer with promising osteoconductive, osteoinductive and osteo-integrative effects in bone regeneration. Chitosan utilization for bone scaffolds combined with other biomaterials, growth factors, or stem cells gives better bone regeneration results than chitosan alone.
COVID-19 and Thrombosis Complication in Children
Authors: Dimiati Herlina , Widasari Nina
Published: December 2022

Since it was discovered in Wuhan in December 2019, most studies on COVID-19 have been centered on symptomatic adults. An expanded pro-inflammatory cytokine reaction, abnormal clot formation, overactive platelets, and hypercoagulable state are among the well-known clinical characteristics of endothelial dysfunction that may arise in patients with COVID-19. These conditions can lead to venous thromboembolism, arterial thrombosis, and pulmonary embolism. To date, the predominance of thromboembolic complications in children infected with severe acute respiratory syndrome coronavirus 2 has not been fully documented, and there is no explicit recommendation for the prevention of thrombosis in children.
Group feature screening based on Gini impurity for ultrahigh-dimensional multi-classification
Authors: Wang Zhongzheng , Deng Guangming , Xu Haiyun
Published: December 2022

Because the majority of model-free feature screening methods concentrate on individual predictors, they are unable to consider structured predictors, such as grouped variables. In this study, we suggest a model-free and direct extension of the original sure independence screening approach for group screening using Gini impurity for a classification model. Compared to current feature screening approaches, the proposed method performs better in terms of screening efficiency and classification accuracy. It was established that the suggested group screening process exhibits sure screening properties and ranking consistency properties under specific regularity conditions. We used simulation studies to illustrate the limited sample performance of the proposed technique and real data analysis.
W-shaped soliton solutions to the modified Zakharov-Kuznetsov equation of ion-acoustic waves in (3+1)-dimensions arise in a magnetized plasma

Published: December 2022

This paper is presented to investigate the exact solutions to the modified Zakharov-Kuznetsov equation that have a critical role to play in mathematical physics. The $ \tan \left(\phi \left(\zeta \right)/2 \right) $-expansion, $ (m+G'(\zeta)/G(\zeta)) $-expansion and He exponential function methods are used to reveal various analytical solutions of the model. The equation regulates the treatment of weakly nonlinear ion-acoustic waves in a plasma consisting of cold ions and hot isothermal electrons throughout the existence of a uniform magnetic field. Solutions in forms of W-shaped, singular, periodic-bright and bright are constructed.
Laboratory and numerical investigation of the 2-array submerged vanes in meandering open channel

Published: December 2022

In the case of flooding in rivers, river regulation structures are important since scours occur on the outer meander due to high flow velocities. In this study, 2-array submerged vane structures were investigated which is a new method in the meandering part of open channels, both laboratory and numerically with an open channel flow discharge of 20 L/s. Open channel flow experiments were carried out by using a submerged vane and without a vane. The flow velocity results of the computational fluid dynamics (CFD) models were compared to the experimental results and the results were found compatible. The flow velocities were investigated along with depth using the CFD and found that the maximum velocity was reduced by 22–27% along the depth. In the outer meander, the 2-array submerged vane with a 6-vane structure was found to affect the flow velocity by 26–29% in the region behind the vane.
The $ p $-Frobenius and $ p $-Sylvester numbers for Fibonacci and Lucas triplets
Authors: Komatsu Takao , Ying Haotian
Published: December 2022

In this paper we study a certain kind of generalized linear Diophantine problem of Frobenius. Let $ a_1, a_2, \dots, a_l $ be positive integers such that their greatest common divisor is one. For a nonnegative integer $ p $, denote the $ p $-Frobenius number by $ g_p (a_1, a_2, \dots, a_l) $, which is the largest integer that can be represented at most $ p $ ways by a linear combination with nonnegative integer coefficients of $ a_1, a_2, \dots, a_l $. When $ p = 0 $, the $ 0 $-Frobenius number is the classical Frobenius number. When $ l = 2 $, the $ p $-Frobenius number is explicitly given. However, when $ l = 3 $ and even larger, even in special cases, it is not easy to give the Frobenius number explicitly. It is even more difficult when $ p > 0 $, and no specific example has been known. However, very recently, we have succeeded in giving explicit formulas for the case where the sequence is of triangular numbers [1] or of repunits [2] for the case where $ l = 3 $. In this paper, we show the explicit formula for the Fibonacci triple when $ p > 0 $. In addition, we give an explicit formula for the $ p $-Sylvester number, that is, the total number of nonnegative integers that can be represented in at most $ p $ ways. Furthermore, explicit formulas are shown concerning the Lucas triple.

Authors: Zhang Xian , Huang Chen
Published: December 2022

We consider a class of modified Schrödinger-Poisson systems with general nonlinearity by variational methods. The existence and multiplicity of solutions are obtained. Besides, when $ V(x) = 1 $ and $ f(x, u) = |u|^{p-2}u $, we obtain some existence and non-existence results for the modified Schrödinger-Poisson systems.

Corona virus’s correct and accurate diagnosis is the most important reason for contributing to the treatment of this disease. Radiography is one of the simplest methods to detect virus infection. In this research, a method has been proposed that can diagnose disease based on radiography (X-ray chest) and deep learning techniques. We conducted a comparative study by using three diagnosis models; the first one was developed by using traditional CNN, while the two others are our proposed models (second and third models). The proposed models can diagnose the COVID-19 infection, normal cases, lung opacity, and Viral Pneumonia according to the four categories in the covid19 radiography dataset. The transfer learning technology had used to increase the robustness and reliability of our model, also, data augmentation was used for reducing the overfitting and to increase the accuracy of the model by scaling rotation, zooming, and translation. The third model showed higher training accuracy of 93.18% compared to the two other models that are dependent on using traditional convolution neural networks with an accuracy of 70.28% of the first model, while the accuracy of the second model that uses data augmentation with traditional convolution neural is 90.1%, while the testing accuracy models was 68.27% for the first model, 87.55% for the second model, and 86.03% for the third model.
Endangered Oarisma poweshiek larvae vary their graminoid forage in Manitoba, Canada
Authors: Henault Justis , Westwood Richard
Published: December 2022

The Poweshiek skipperling (Oarisma poweshiek) is endemic to the tall grass prairie in North America and is now critically endangered globally. Existing populations are scattered among tall grass prairie remnants. However, the host food plants eaten by Poweshiek skipperling larvae, the vegetative and microclimatic descriptions of immature and adult microhabitats, and O. poweshiek behaviour in Manitoba are unknown. We followed Poweshiek skipperling adults in their natural habitat to locate microhabitats where eggs were laid and to observe larval foraging behaviour and development. We measured vegetative, structural, and microclimatic characteristics of microhabitats used by immatures and documented the host species larvae consumed, their general behaviour (on plants; movement within microhabitats), and their developmental schedules. Larvae ate Andropogon gerardi, Muhlenbergia richardsonis, Sporobolus heterolepis, and Schizachyrium scoparium (all Poaceae) in natural tall grass prairie. Larvae appeared to navigate microhabitats to locate host food plants, alternating between shoots of various species throughout their development. Microhabitats seemed to be more open, with drier microclimates, than areas where eggs were not laid. This improved understanding of larval feeding patterns, adult behaviours, and microhabitat attributes may help local grassland stewards and researchers reduce the list of possible causes of decline and identify potential solutions to recover the Poweshiek skipperling.
Fruitful female fecundity after feeding Gryllodes sigillatus (Orthoptera: Gryllidae) royal jelly

Published: December 2022

Dietary honey bee royal jelly increases insect growth rates and adult body size. Royal jelly as a dietary supplement could enhance mass insect production by increasing the body size of mass-reared model species. To determine the effect of royal jelly on a cricket species, Gryllodes sigillatus Walker (Orthoptera: Gryllidae), farmed for human consumption, we ran two experiments. We tested the dose-dependent response of G. sigillatus to royal jelly using a range of diets across 0–30% w/w royal jelly. We also measured the individual-level life history responses to royal jelly over time by individually rearing G. sigillatus nymphs on two separate diets: half were fed a commercial cricket diet, and half were fed the same diet mixed with 15% w/w fresh royal jelly. We found sex-dependent effects: females fed the royal jelly diet were 30% heavier, and this effect was driven by significantly longer abdomens containing 67% more eggs compared to those fed the standard diet. Female mass was optimised at approximately 17% w/w royal jelly. Our results reveal that although a royal jelly dietary supplement can increase the yield of mass-reared insects, the life history responses are species and sex specific.
Severe cicatricial entropion repair using mucous membrane graft in Stevens–Johnson syndrome
Authors: Adewara Bolajoko , Singh Swati
Published: December 2022

Background:

Severe cicatricial entropion in Stevens–Johnson syndrome (SJS) patients is difficult to treat and is associated with a higher recurrence rate. Also, entropion in the presence of lid margin mucous membrane graft (MMG) further complicates the surgical anatomy and approach.

Purpose:

To report a modified surgical technique of repairing severe upper eyelid cicatricial entropion in an SJS patient with history of lid margin MMG.

Synopsis:

Cicatricial entropion in patients with SJS is entirely different from trachomatous cicatricial entropion. The involvement of the lid margin with keratinization, tarsal scarring, persistent conjunctival inflammation, and unhealthy ocular surface affects the surgical approach and outcomes. Conjunctiva-sparing surgery with reconstruction of the lid margin using MMG, flattening and repositioning the anterior lamella, and covering the bare tarsus with MMG rather than leaving it raw are the necessary modifications in this technique from conventional anterior lamellar recession. The video demonstrates the surgical technique for harvesting and preparation of a labial MMG, the splitting of the anterior and posterior lamella of the lid margin, scar tissue release between the lash line and the tarsus, repositioning of the anterior lamella, and anchoring of the labial MMG.

Highlights:

Anterior lamellar recession combined with MMG wrapping the lid margin and bare tarsus offers good cicatricial entropion repair outcomes. Removal of fat and submucosa from the mucosal graft should be done for better cosmesis. Adequate separation of the scar tissues from the lash line and the tarsus is essential.
