Merebaknya kasus covid-19 di Indonesia mengakibatkan munculnya berbagai permasalahan, tidak hanya berdampak pada sektor kesehatan tetapi juga sektor sosial ekonomi. Dalam dunia kesehatan, peningkatan jumlah pasien yang semakin banyak membuat sejumlah fasilitas kesehatan yang ditunjuk mengalami kekurangan tenaga dalam melakukan tugasnya. Hal ini mendorong pemerintah dan lembaga yang ditunjuk dalam penanganan covid-19 membuka pendaftaran relawan baik medis maupun non medis untuk mempercepat penanganannya. Selain penanganan kasus positif, langkah-langkah pencegahan juga menjadi fokus utama dalam menekan penyebaran dan peningkatan kasus covid-19. Beberapa langkah pencegahan diantaranya adalah  penggunaan masker, mencuci tangan menggunakan sabun atau hand sanitizer, pembatasan interaksi langsung dan sterilisasi ruang publik seperti rumah ibadah, sekolah, dan tempat pelayanan umum lainnya. Namun, saat ini produk-produk yang berkaitan dengan tindakan pencegahan menjadi langka dan bernilai tinggi sehingga banyak masyarakat yang tidak dapat memperolehnya. Dalam mengatasi permasalahan ini, dibutuhkan bantuan berupa jasa maupun produk yang dapat digunakan untuk melakukan tindakan pencegahan. Kondisi ini kemudian mendorong berbagai lapisan masyarakat baik secara individu maupun organisasi untuk turut membantu dalam pencegahan dan penanganan covid-19. Di sisi lain, banyaknya permintaan yang diajukan membuat calon pemberi jasa kesulitan dalam menentukan penerima bantuan yang benar-benar membutuhkan. Untuk itu, dalam penelitian ini diusulkan suatu sistem informasi yang dapat mempertemukan calon pemberi jasa dengan calon penerima bantuan yang berhak. Sistem ini diharapkan dapat mempercepat proses perekrutan relawan untuk penanganan kasus covid-19 dan penyaluran bantuan jasa yang dibutuhkan dalam pencegahannya.

—Salah satu langkah pencegahan penyebaran virus COVID-19 dapat dilakukan dengan cara melakukan karantina terhadap kelompok orang berisiko diantaranya ODP (Orang Dalam Pemantauan) selama 14 hari dan surveilans/pemantauan kondisi kesehatan ODP tersebut selama masa karantina sebagaimana panduan yang diterbitkan Kementrian Kesehatan Indonesia berupa Kartu Kewaspadaan Kesehatan Pedoman dan Pencegahan Pengendalian COVID-19. Upaya karantina/isolasi mandiri dilakukan sebagai metoda untuk membatasi seseorang atau sekelompok orang dalam suatu wilayah yang diduga terinfeksi penyakit dan/atau terkontaminasi. Namun pemantauan terhadap kepatuhan pelaksanaan isolasi mandiri sulit dilakukan karena puskesmas sebagai unit fasilitas kesehatan yang ditugaskan untuk melakukan pemantauan tidak memiliki alat pantau yang dapat menjamin kepatuhan ODP selama masa isolasi. PERISAI merupakan sistem informasi yang bertujuan untuk mendukung pemantauan ODP yang dapat dilaksanakan secara merata diseluruh daerah terutama bagi penduduk yang baru tiba setelah melakukan perjalanan dari daerah yang memiliki riwayat transmisi lokal COVID-19 dengan konsep digitisasi Kartu Kewaspadaan Kesehatan. PERISAI dikembangkan terbatas pada pengelolaan informasi ODP yang dapat digunakan oleh puskesmas dibawah naungan dinas kesehatan di lingkungan Kabupaten/Kota. Dengan demikian, petugas puskesmas dapat memonitoring proses isolasi mandiri yang dilakukan oleh ODP melalui aplikasi web dan ODP juga dapat melaporkan kondisi kesehatannya secara berkala melalui aplikasi mobile. Sistem informasi PERISAI dikembangkan menggunakan model pengembangan protoyping yang menghasilkan beberapa modul sistem yaitu web aplikasi, mobile aplikasi serta REST API sebagai alat komunikasi sistem

Corona Virus Desease (COVID-19) pertama kali dilaporkan di Wuhan pada Desember 2019. Kemudian menyebar ke berbagai bagian Tiongkok, dan secara bertahap menjadi pandemi global pada Maret 2020. Sementara jumlah kematian terus meningkat, besaran korban telah bergeser dari Asia ke Eropa, dan ke Amerika Serikat (AS). Makalah ini menganalisis respon di negara-negara Tiongkok, Korea Selatan (Korsel), Italia, dan AS, dan memberikan gambaran bagaimana pemanfaatan Artificial Intelligence (AI) dan Big Data. Sementara negara-negara ini memiliki mekanisme tata kelola yang berbeda, ditemukan bahwa beberapa kebijakan penerapan iptekin AI dan Big Data di masing-masing negara memiliki kekhasan. Pandemi memang bersifat global, namun respon masing-masing negara sangat tergantung pada kondisi lokal. Mengingat respon terhadap penyebaran infeksi COVID-19 tersebut tergantung pada kepentingan dan urgensinya, penerapan AI dan Big Data di Tiongkok, Korsel, dan Italia mempunyai kesamaan. Negara-negara ini cenderung menerapkan AI dan Big Data lebih pada strategi pelandaian kurva sementara AS lebih cenderung menerapkan strategi peningkatan kemampuan pelayanan kesehatan.

COVID-19, sebagai penyakit menular yang disebabkan oleh virus SARS-CoV-2 yang baru ditemukan, telah menjadi pandemi yang sedang dihadapi oleh banyak kota di dunia, tak terkecuali di DKI Jakarta. Salah satu dampak pandemi ini adalah terbatasnya mobilitas publik atau pergerakan masyarakat. Pemerintah Provinsi DKI Jakarta perlu membuat kebijakan yang dapat mengatur mobilitas penduduknya dalam rangka mengurangi risiko penyebaran virus COVID-19. Dalam artikel ini, Exploratory Data Analysis (EDA) dilakukan untuk menganalisis dan mengevaluasi pengaruh dari kebijakan yang telah dibuat oleh Pemerintah Provinsi DKI Jakarta terhadap mobilitas masyarakat di Jakarta. Data yang digunakan di antaranya adalah data harian COVID-19 dari Dinas Kesehatan DKI Jakarta, data rata-rata kecepatan kendaraan di jalan-jalan yang dilewati oleh pengguna aplikasi Waze, data tren pergerakan masyarakat selama pandemi COVID-19 yang diperoleh dari Google COVID-19 Community Mobility Reports, serta data Apple Mobility Trends Reports yang merupakan data tren pergerakan masyarakat berdasarkan kategori berkendara dan berjalan. Melalui hasil analisis data yang dilakukan, terlihat bahwa tingkat mobilitas di DKI Jakarta lebih rendah pada saat diberlakukannya Pembatasan Sosial Berskala Besar (PSBB), yang kemudian berpengaruh terhadap penekanan jumlah kasus positif harian di DKI Jakarta. Penurunan mobilitas ini diharapkan menjadi langkah penting dalam menangani COVID-19 di DKI Jakarta.

Top Ten Improv Games for EFL Classrooms
Authors: White Jason
Published: September 2020

This paper focuses on improvisation (also known as improv), which is one of the dramatic techniques that teachers are using in EFL classrooms today. Many teachers have found that improvisation is valuable for a multitude of reasons, including increasing student motivation and lowering foreign language anxiety, creating a positive learning environment, and generally increasing the level of enjoyment for foreign language students. There are numerous possibilities for teachers who would like to use improv games as a main component, or as a supplement, to the standard curriculum in their foreign language classes. This paper discusses the history of improvisation, and then gives a detailed explanation of ten popular improv games that teachers can use in their classes. It should be noted that these games are discussed as used by the author and may not match exactly with the definitions or parameters of similar games found on improvisation websites or in books about improvisation.

Published: September 2020

Herein we report the synthesis and characterization of a new series of styryl-based push-pull dyes containing a free amino group and their Schiff base derivatives. The dyes include the dicyanomethylene group as an acceptor and different para-substituted alkylamines as donors. Morever as a proton-sensitive group a pyridin-2-yl substituent was attached to the para-position of the phenyl moiety in both series of compounds. The photophysical properties of the dyes were examined in various solvents with different polarities and showed absorption in the visible region and green-red emission with low quantum yields. The absorption and the emission maxima were shifted bathocromically by increasing the solvent’s polarity. However, there was no correlation with the polarity parameters of the solvents. The pH-sensitive properties of all prepared Schiff bases were examined against TBAOH in DMSO, via deprotonation of the OH group in the salicylidene moiety and their reverse protonation was also investigated using TFA. The Schiff bases exhibited a bathochromic shift upon the addition of TBAOH to their solutions in DMSO. Therefore, they showed potential to be utilized as colorimetric and luminescence pH sensors. The second-order nonlinear optical (NLO) responses of the dyes were measured by the electric field-induced second harmonic (EFISH) generation method. The highest μβ values were obtained for the dyes bearing the julolidine donor as 1430 × 10−48 esu (for free amino derivative) and 1950 × 10−48 esu (for Schiff base derivative), respectively. The structural and electronic properties of the dyes as well as their NLO properties were further studied using DFT calculations. The thermal stabilities of all dyes were evaluated by thermogravimetric analysis (TGA). The TGA data showed that all dyes were thermally stable up to 250 °C.

Characteristics and Determinants of New Start-ups in Gujarat, India
Authors: Kumar Ajay , Jyoti Bhim
Published: September 2020

Purpose: This study examines the relationship of socio-economic characteristics of start-ups with their size in Gujarat, India. It also assesses the determinants affecting the annual sale of start-ups.

Methods: It includes primary information based on a survey of 120 founders of start-ups. Linear and semi-log linear regression models have been applied to assess the determinants of start-ups. Probit regression models have been considered to assess the factors affecting the annual sale of the start-ups.

Results: Stage of start-up, the participation of founders in conferences, educational qualification, and new products launched by start-ups, professional connections of founders, source of funding, and support from incubator/accelerator/supporting organizations are found crucial determinants of start-up size in Gujarat. The annual sales of the start-ups are positively associated with stage of start-up, support from a mentor, team members, founder's academic qualification, and collaboration with national or international organizations, unskilled workers.

Implications: Technology transfer and commercialization, development of new products, government regulations, the requirement of costumers, free rights for entrepreneurs, appropriate financial support for new entrepreneurs, transparency and clarity in government policies, the establishment of high-tech start-ups, and development of digital infrastructure, increase in R&D spending in research academia, and association of research institutions with entrepreneurs would be conducive to create an appropriate start-ups ecosystem and to reduce regional development disparities across Indian states. Subsequently, it would be helpful to increase sustainable development in India. 

Originality: This study has used primary information of 120 founders of start-ups to assess the determinants, and the factors affecting annual sales of start-ups using the regression model in, Gujrat, India. Thus, it has an empirical contribution to the body of knowledge.

Limitations: This study could not provide rational justifications on most factors that show an insignificant impact on start-ups due to the small sample size. Further research, therefore, may be considered to identify the association of start-up size with the variables using a large sample size in India.
Black Hole Genealogy: Identifying Hierarchical Mergers with Gravitational Waves
Authors: Kimball Chase , Talbot Colm , L. Berry Christopher P. , Carney Matthew , Zevin Michael , Thrane Eric , Kalogera Vicky
Published: September 2020

In dense stellar environments, the merger products of binary black hole mergers may undergo additional mergers. These hierarchical mergers are naturally expected to have higher masses than the first generation of black holes made from stars. The components of hierarchical mergers are expected to have significant characteristic spins, imprinted by the orbital angular momentum of the previous mergers. However, since the population properties of first-generation black holes are uncertain, it is difficult to know if any given merger is first-generation or hierarchical. We use observations of gravitational waves to reconstruct the binary black hole mass and spin spectrum of a population including the possibility of hierarchical mergers. We employ a phenomenological model that captures the properties of merging binary black holes from simulations of globular clusters. Inspired by recent work on the formation of low-spin black holes, we include a zero-spin subpopulation. We analyze binary black holes from LIGO and Virgo’s first two observing runs, and find that this catalog is consistent with having no hierarchical mergers. We find that the most massive system in this catalog, GW170729, is mostly likely a first-generation merger, having a 4% probability of being a hierarchical merger assuming a 5 × 105
M
⊙ globular cluster mass. Using our model, we find that 99% of first-generation black holes in coalescing binaries have masses below

M
⊙, and the fraction of binaries with near-zero component spins is less than

(90% probability). Upcoming observations will determine if hierarchical mergers are a common source of gravitational waves.

We present very early ground-based optical follow-up observations of gamma-ray burst (GRB) 140423A, which was discovered by the Swift/Burst Alert Telescope (BAT) and by the Fermi/Gamma-Ray Burst Monitor. Its broadband afterglow was monitored by the Swift/X-Ray Telescope and ground-based optical telescopes from T
0 + 70.96 s to 4.8 days after the Swift/BAT trigger. This is one more case of a prompt optical emission observation. The temporal and spectral joint fits of the multiwavelength light curves of GRB 140423A reveal that achromatic behavior is consistent with the external shock model, including a transition from a stellar wind to the interstellar medium (ISM) and energy injection. In terms of the optical light curves, there is an onset bump in the early afterglow with a rising index

(peaking at

s). It then decays with a steep index

Gravitational-wave Capture in Spinning Black Hole Encounters
Authors: Bae Yeong-Bok , Lee Hyung Mok , Kang Gungwon
Published: September 2020

The orbits of two black holes (BHs) that are initially unbound can be transformed into bound orbits by emitting gravitational waves during close encounters in a star cluster, which is called gravitational-wave (GW) capture. The effects of spin of BHs on GW capture are investigated in the context of numerical relativity. The radiated energy during the encounter is dependent on the effective spin when the BHs have equal masses, as expected from post-Newtonian approximation. The strongest emission is produced when the spins of both BHs are anti-aligned to the orbital angular momentum in the case of fly-by encounters. But the opposite is true in the case of direct merging: the strongest emission comes from the BHs with aligned spins to the orbital angular momentum. The fraction of direct merging among the GW captures increases in proportion to v
4/7, assuming the uniform distribution of pericenter distances in the encounters, where v is the velocity dispersion of the cluster, which means about 5% of GW capture leads to the direct merging for star clusters with v = 150 km s−1.
The Role of Infrared Radiation Pressure in Shaping Dusty Winds in AGNs
Authors: Venanzi Marta , Hönig Sebastian , Williamson David
Published: September 2020

The detection of dusty winds dominating the infrared emission of active galactic nuclei (AGNs) on parsec scales has revealed the limitations of traditional radiative transfer models based on a toroidal distribution of dusty gas. A new, more complex, dynamical structure is emerging and the physical origin of such dusty winds has to be critically assessed. We present a semi-analytical model to test the hypothesis of radiatively accelerated dusty winds launched by the AGN and by the heated dust itself. The model consists of an AGN and an infrared radiating dusty disk, the latter being the primary mass reservoir for the outflow. We calculate the trajectories of dusty gas clumps in this environment, accounting for both gravity and the AGN radiation as well as the re-radiation by the hot, dusty gas clouds themselves. We find that the morphology consists of a disk of material that orbits with sub-Keplerian velocities and a hyperboloid polar wind launched at the inner edge of the dusty disk. This is consistent with high-angular resolution infrared and sub-mm observations of some local Seyfert AGN. The strength of the wind and its orientation depend on the Eddington ratio and the column density of the dusty clumps, which is in agreement with proposed radiation regulated obscuration models developed for the X-ray obscuring material around AGNs.

We report on the discovery of drifting subpulses from the Vela pulsar, observed using the Yunnan 40 m radio telescope at 6800 MHz observing frequency. The single pulses show the presence of two distinct drifting patterns, where the central component is modulated in longitude and amplitude simultaneously with a period of 9 pulses, and the trailing component remains phase stationary within the pulse window but periodically changes in intensity with a period of 29 pulses. The leading component emission remains constant in intensity and pulse phase. Such periodic modulation in the Vela pulsar is a separate phenomenon from periodic nulling and traditional subpulse drifting, which may lead to a greater understanding of the pulse emission mechanism.
Cross Sections of Coronal Loop Flux Tubes
Authors: Klimchuk James A. , DeForest Craig E.
Published: September 2020

Coronal loops reveal crucial information about the nature of both coronal magnetic fields and coronal heating. The shape of the corresponding flux tube cross section and how it varies with position are especially important properties. They are a direct indication of the expansion of the field and of the cross-field spatial distribution of the heating. We have studied 20 loops using high spatial resolution observations from the first flight of the Hi-C rocket experiment, measuring the intensity and width as a function of position along the loop axis. We find that intensity and width tend to either be uncorrelated or to have a direct dependence, such that they increase or decrease together. This implies that the flux tube cross sections are approximately circular under the assumptions that the tubes have nonnegligible twist and that the plasma emissivity is approximately uniform along the magnetic field. The shape need not be a perfect circle and the emissivity need not be uniform within the cross section, but subresolution patches of emission must be distributed quasi-uniformly within an envelope that has an aspect ratio of order unity. This raises questions about the suggestion that flux tubes expand with height, but primarily in the line-of-sight direction so that the corresponding (relatively noticeable) loops appear to have roughly uniform width, a long-standing puzzle. It also casts doubt on the idea that most loops correspond to simple warped sheets, although we leave open the possibility of more complex manifold structures.
Turbulence in the Very Local Interstellar Medium (VLISM)
Authors: Zhao L.-L. , Zank G. P. , Burlaga L. F.
Published: September 2020

The Voyager 1 spacecraft has been observing interstellar magnetic turbulence since it crossed the heliopause in 2012. Burlaga et al. reported that the turbulence appears to be compressible close to the heliopause and becomes incompressible farther away. In this paper, we undertake a more detailed analysis of the magnetic fluctuations measured by Voyager 1 from 2013 to 2019. We apply the techniques of wavelet analysis and Hilbert spectral analysis. These methods reveal temporal or spatial variations of the fluctuations that are not easily apparent using standard Fourier techniques. Our results suggest that the compressible fluctuations are confined to a smaller region than previously thought.

Published: September 2020

The recent Chandra discovery of extended ∼kiloparsec-scale hard (>3 keV) X-ray emission in nearby Compton-thick (CT) active galactic nuclei (AGN) opens a new window to improving AGN torus modeling and investigating how the central supermassive black hole interacts with and impacts the host galaxy. Since there are only a handful of detections so far, we need to establish a statistical sample to determine the ubiquity of the extended hard X-ray emission in CT AGN and quantify the amount and extent of this component. In this paper, we present the spatial analysis results of a pilot Chandra imaging survey of seven nearby (

) CT AGN selected from the Swift-BAT spectroscopic AGN survey. We find that five out of the seven CT AGN show extended emission in the 3–7 keV band detected at >3σ above the Chandra point-spread function (PSF), with ∼12%–22% of the total emission in the extended components. ESO 137-G034 and NGC 3281 display biconical ionization structures with extended hard X-ray emission reaching kiloparsec scales (∼1.9 and 3.5 kpc in diameter). The other three show extended hard X-ray emission above the PSF out to at least ∼360 pc in radius. We find a trend that a minimum 3–7 keV count rate of 0.01 counts s−1 and total excess fraction >20% are required to detect a prominent extended hard X-ray component. Given that this extended hard X-ray component appears to be relatively common in this uniformly selected CT AGN sample, we further discuss the implications for torus modeling and AGN feedback.
Tracing the Intrinsic Shapes of Dwarf Galaxies Out to Four Effective Radii: Clues to Low-mass Stellar Halo Formation

Though smooth, extended spheroidal stellar outskirts have long been observed around nearby dwarf galaxies, it is unclear whether dwarfs generically host an extended stellar halo. We use imaging from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) to measure the shapes of dwarf galaxies out to four effective radii for a sample of 6758 dwarfs at 0.005 < z < 0.2 and 107.0 < M

⊙, the galaxies grow from thick disk-like at one effective radius toward the spheroidal extreme at four effective radii. We also see that although blue dwarfs are, on average, characterized by thinner disks than red dwarfs, both blue and red dwarfs grow more spheroidal as a function of radius. This relation also holds true for a comparison between field and satellite dwarfs. This uniform trend toward relatively spheroidal shapes as a function of radius is consistent with an in situ formation mechanism for stellar outskirts around low-mass galaxies, in agreement with proposed models where star formation feedback produces round stellar outskirts around dwarfs.
