The Parameters Comparison of the “Starlink” LEO Satellites Constellation for Different Orbital Shells
Authors: Cakaj Shkelzen 
Published: May 2021

Communications-integrated satellite-terrestrial networks used for global broadband services have gained a high degree of interest from scientists and industries worldwide. The most convenient structures for such use are low Earth orbit satellites, since they fly closer to the Earth compared to the other orbits, and consequently provide significantly lower latency, which is essential for reliable and safe communications. Among these efforts is the Starlink satellites constellation, developed and partly deployed by the United States Company SpaceX. The constellation is planned to be organized in three spatial shells, each of them made up of several hundreds of small-dimensioned and light-weighted low Earth orbit specially designed satellites to provide broadband services, intending to offer global Earth coverage through their interoperability, combined also with the ground stations as a part of the satellite-terrestrial integrated network. By October 24, 2020, 893 satellites are situated in orbit of altitudes of 550 km under different inclinations, determining the first Starlink orbital shell. Two next generations are planned to be situated at altitudes of 1,110 and 340 km, to complete the appropriate infrastructure of three Starlink satellite shells, toward a global presence of broadband internet services. These three orbital shells offer different space views seen from the ground station (user) because of their different altitudes, thus in this paper a few parameters which describe the satellite’s behavior considered from the ground station’s (user’s) point of view are compared. These parameters in fact stem from the space orbital parameters and are defined as: horizon plane wideness, slant range, latency, and coverage area. A comparison is given for the three Starlink orbit layers, with identification of appropriate drawbacks and advantages as performance indicators. By the end, these parameters are applied to geometrically interpret and confirm the handover process among satellites. This paper may serve to highlight the new challenges of the satellite-terrestrial integrated network, providing some theoretical analysis and performance comparisons for the satellites in different orbit layers seen from the ground station (user) perspective.

Background:Brucellosis, a zoonotic disease, infects various hosts, including swine and humans. It has reemerged in recent years as a public health concern, and current studies on brucellosis infection in swine have been conducted worldwide. However, no meta-analyses of global brucellosis infection in swine have been published. The aim of this study was to provide an overview ofBrucellaspecies (spp.) in swine worldwide and the factors associated with its persistence.Results:We searched seven databases for published epidemiological studies on brucellosis in pigs, including the Chinese National Knowledge Infrastructure, Wanfang Data, SpringerLink, ScienceDirect, Web of Science, the VIP Chinese Journal Database and PubMed. We selected 119 articles published from January 1, 2000 to January 3, 2020 for inclusion in the meta-analysis and analyzed the data using a random-effects model. Funnel plots and Egger's test showed significant publication bias in the included studies. The results of the sensitivity analysis showed that our study was relatively stable and reliable. The prevalence of brucellosis in swine was 2.1% (95% CI: 1.6–2.6), of which the highest infection rate, which was found in Europe, was 17.4% (95% CI: 11.1–24.9). The prevalence in feral pigs (15.0%, 95% CI: 8.4–23.2) was higher than that in domestic pigs (1.1%, 95% CI 0.2–2.5). The prevalence in high-income countries (15.7%, 95% CI 8.0–25.3) was significantly higher than that in middle- (0.8%, 95% CI 0.5–1.1), and low-income countries (0.1%, 95% CI 0.0–0.2). The prevalence was highest in finishing pigs at 4.9% (95% CI 0.9–11.0), and lowest among suckling pigs at 0% (95% CI 0.0–0.5).Conclusion:TheBrucellaprevalence in pig herds currently is distributed widely throughout the world. In some countries, swine brucellosis may be a neglected zoonotic disease. We recommend long-term monitoring of the prevalence of brucellosis in domestic and wild pig herds. Attention should also be paid to animal welfare on intensive pig farms; controlling the breeding density may play an important role in reducing the spread of brucellosis among pigs.

Coccidioides immitis and C. posadasii are dimorphic fungi that transform from mycelia with internal arthroconidia in the soil to a tissue form known as a spherule in mammals. This process can be recapitulated in vitro by increasing the temperature, CO2 and changing other culture conditions. In this study, we have analyzed changes in gene expression in mycelia and young and mature spherules. Genes that were highly upregulated in young spherules include a spherule surface protein and iron and copper membrane transporters. Genes that are unique to Coccidioides spp. are also overrepresented in this group, suggesting that they may be important for spherule differentiation. Enriched GO terms in young spherule upregulated genes include oxidation-reduction, response to stress and membrane proteins. Downregulated genes are enriched for transcription factors, especially helix–loop–helix and C2H2 type zinc finger domain-containing proteins, which is consistent with the dramatic change in transcriptional profile. Almost all genes that are upregulated in young spherules remain upregulated in mature spherules, but a small number of genes are differentially expressed in those two stages of spherule development. Mature spherules express more Hsp31 and amylase and less tyrosinase than young spherules. Some expression of transposons was detected and most of the differentially expressed transposons were upregulated in spherules.

To be a priest, a candidate should study philosophy and theology for more or less seven years of duration which is called Initial Formation, which emphasize four dimensions, which are human being, spiritual, intellectual and pastoral. These dimensions are built up at formation house and college. If Initial Formation is passed through, the candidate is anointed to be a priest and he is ready as in persona Christi for pastoral service who has responsibility and duty in the church and the world. For this service, the priest needs a formation for long his priesthood which is called Ongoing Formation. The dimension which is emphasized at Initial Formation is also given in his priesthood with contents combined by pastoral service and stages of priest, which are junior, middle ages, advanced years and retired or sick. The intention of Ongoing Formation is to support the priesthood for the long life of a priest in order to always embody him with the Great Pastor in life and pastoral service.

Nas últimas décadas, o crescimento da urbanização vem provocando grandes transformações nos aspectos sociais, econômicos e morfológicos nas áreas costeiras. As praias urbanas de Boa Viagem e Pina (Recife-PE) e a praia de Piedade (Jaboatão dos Guararapes-PE) têm apresentado estes aspectos, onde se observa vulnerabilidade costeira à erosão. O objetivo deste trabalho é analisar o deslocamento espacial e temporal da linha de costa. Para isto modelouse a massa de dados obtida do método de levantamento geodésico relativo cinemático, o qual possibilita o monitoramento da linha de costa, para os anos de 2007, 2009, 2010 e 2012. Foi empregado o método de transectos, o qual é necessário adotar uma linha de costa como base, 2007. E foi dividida a área de estudo em 6 setores para que se pudesse analisar o deslocamento médio da linha de costa. Os setores 1 e 5 apresentam acreção em todos os períodos analisados (2007-2009, 2007-2010, 2007-2012). O setor 2 apresentou erosão em todos os períodos analisados. Os setores 3 e 6 nos períodos de 2007-2009 e 2007-2010, apresentaram erosão, enquanto de 2007-2012 apresentaram tendência a acreção. Destacase que no setor 4 não se realizou o cálculo devido ser a área que apresenta enrocamento. Esse estudo tende a contribuir para análise do comportamento temporal nos projetos de tomadas de decisões em ambientes costeiros.

Золотой век поэтического двуязычия: французские переводы Баратынского

Pour Evgenij Baratynskij (1800-1844), poète romantique de l’Âge d’or de la poésie russe, comme pour tous aristocrates russes du XIXe siècle, écrire en français était absolument naturel. À Paris durant l’hiver 1843-1844 sur la demande d’Adolphe de Circourt et de ses confrères français, tel que Prosper Mérimée, il a traduit en français certains de ses poèmes. En choisissant de traduire en prose Baratynskij n’a pas seulement sacrifié à la tradition de cette époque-là, son choix était sans doute aussi motivé par une démarche de nature métapoétique. À la différence d’autres études textologiques qui remettent en question la paternité de ces traductions en leur attribuant un travail collectif, les quinze poèmes en prose de l’édition de 1914 de M. Gofman sont étudiés ici, en questionnant les problèmes de la traduction poétique : le choix de la traduction en prose et une conception de la poésie comme étant déjà une traduction et une mise à l’écart. L’article privilégie une approche de traductologie et de poétique qui questionne non pas la paternité de ces traductions, mais le phénomène même de bilinguisme poétique dans le contexte du bilinguisme de la noblesse russe du XIXe. Laissant de côté la question de l’attribution des traductions françaises de poésies de Baratynskij, déjà traitée par d’autres chercheurs, l’auteur s’attache à montrer comment Baratynskij a cherché à rendre sa prose poétique.

Published: May 2021

Abstract
We demonstrated photonic band characterization in photonic crystals (PhCs) based on InGaN/GaN nanocolumn (NC) arrays fabricated by Ti-mask selective area growth. Triangular and honeycomb latticed NCs with approximately the same diameter and closest distance were successfully fabricated. To effectively observe the photonic bands, we designed an angle-resolved micro-photoluminescence measurement system. The photonic bands in the honeycomb lattice were at longer wavelengths compared with those in the triangular lattice, indicating that, for the honeycomb lattice, narrower NCs were available to realize PhC effects in the long-wavelength region. Therefore, narrow honeycomb lattices with large nanocrystalline and PhC effects are suitable for long-wavelength emission.
Mid-air acoustic tweezers for non-contact pick up using multi-channel controlled ultrasonic transducer arrays
Authors: Kondo Shota , Okubo Kan 
Published: May 2021

Abstract
Ultrasonic transducer arrays realize non-contact manipulation using acoustic radiation force. Non-contact pick-up conventionally uses hemispherical ultrasonic arrays. However, particles on reflective stages cannot be picked up. In this study, we propose a multi-channel hemispherical ultrasonic transducer array for non-contact pick-up on a rigid stage with reflection. The phase and amplitude of each channel are optimized using the sound reproduction method. This creates an acoustic trap at only the desired position, and pick up can thus be realized on the rigid stage. To the best of our knowledge, this is the first study to demonstrate non-contact pickup using this approach.
Acoustic sensing method for an occlusion area with super-directional sound sources and multiple modulation signal
Authors: Koyama Seiji , Okubo Kan , Tagawa Norio 
Published: May 2021

Abstract
Several signal types such as sound waves, radio waves, lights, and lasers are currently being used for sensing technology. This study focuses on acoustic sensing in air and it attempts to detect an object in an occluded area. Sound waves in the audible range have a long wavelength. The wraparound of waves is caused by diffraction and it appears conspicuously. Low-frequency sound waves can detect objects that are hidden behind other objects via diffraction. This study investigates occlusion area sensing by using a single transmission with a multiple modulation signal. In addition, a sensing system is proposed that can efficiently identify objects in occlusion area. Applying a multiple modulation signal to sensing systems can reduce the cost of transmitting the coded signals. The results from this investigation demonstrate that the proposed method is feasible to detect objects in occlusion areas.

Abstract
In this work we have developed, for the first time to our knowledge, an actively Q-switched Tb:LiYF4 laser with emission directly into the green spectral region at 544 nm. Using an acousto-optical modulator, the laser delivered an average power of 445 mW at 3 kHz repetition rate for an incident pump power of 3 W at 488 nm. The laser pulse energy and the pulse duration were measured to be 148 μJ and 190 ns, respectively, indicating a pulse peak power of 580 W with output transmittance of 10%. The laser could be operated up to a repetition rate of 16 kHz with output transmittance of 2%.

) epitaxial layers over a wide range of donor concentration (2.1 × 1015–3.2 × 1018 cm−3) and temperature (298–600 K). We obtained μ
H,// of 1160 cm2 V−1s−1, which is the highest electron mobility ever reported for SiC measured at room temperature. The anisotropy of drift mobility becomes smaller at higher temperature and with higher donor concentration. This result can be qualitatively explained by smaller anisotropy of electron effective mass in the high-energy region of the conduction band.
Interfacial spin-orbit torque and spin transparency in Co/Pt bilayer
Authors: Moriya Hiroyuki , Musha Akira , Ando Kazuya 
Published: May 2021

Abstract
We show that interfacial spin–orbit coupling is an efficient source of spin-orbit torques in a Co/Pt bilayer, a prototypical spin-orbitronic device. We find that the spin–orbit coupling at the Co/Pt interface can be effectively manipulated by inserting a thin TiN layer. We show that the strong spin–orbit coupling at the Co/Pt interface enables efficient generation of interfacial spin-orbit torques, as well as suppresses bulk spin-orbit torques, resulting in the dominance of the interfacial contribution in the generation of the spin-orbit torques. This result provides an important information for developing efficient spin-orbitronic devices based on the interfacial spin–orbit coupling.

Almost all Permutation Matrices have Bounded Saturation Functions
Authors: Geneson Jesse 
Published: May 2021

Saturation problems for forbidden graphs have been a popular area of research for many decades, and recently Brualdi and Cao initiated the study of a saturation problem for 0-1 matrices. We say that a 0-1 matrix $A$ is saturating for the forbidden 0-1 matrix $P$ if $A$ avoids $P$ but changing any zero to a one in $A$ creates a copy of $P$. Define $\mathrm{sat}(n, P)$ to be the minimum possible number of ones in an $n \times n$ 0-1 matrix that is saturating for $P$. Fulek and Keszegh proved that for every 0-1 matrix $P$, either $\mathrm{sat}(n, P) = O(1)$ or $\mathrm{sat}(n, P) = \Theta(n)$. They found two 0-1 matrices $P$ for which $\mathrm{sat}(n, P) = O(1)$, as well as infinite families of 0-1 matrices $P$ for which $\mathrm{sat}(n, P) = \Theta(n)$. Their results imply that $\mathrm{sat}(n, P) = \Theta(n)$ for almost all $k \times k$ 0-1 matrices $P$.
Fulek and Keszegh conjectured that there are many more 0-1 matrices $P$ such that $\mathrm{sat}(n, P) = O(1)$ besides the ones they found, and they asked for a characterization of all permutation matrices $P$ such that $\mathrm{sat}(n, P) = O(1)$. We affirm their conjecture by proving that almost all $k \times k$ permutation matrices $P$ have $\mathrm{sat}(n, P) = O(1)$. We also make progress on the characterization problem, since our proof of the main result exhibits a family of permutation matrices with bounded saturation functions.
