The faster development of wireless communications has made the spectrum ending up with increasingly with more shortage. The idea of CR was proposed to meet the problem of spectrum effectiveness. In the cognitive networks, the SUs are permitted to detect, distinguish and access the frequency bands that are not at present used by the PU’s. the SU’s must outfit with the spectrum access information to use the primary user’s licence in the home region network. We propose a maximum throughput and power based cognitive radio for home region systems (HAN). At the point when there are different SU’s and numerous channels, spectrum sharing must be taken into account. In this paper we additionally propose a system of multiple channel sensing. We consider the interference to PU brought about by the dynamic access and the erroneous spectrum sensing technique. We investigate the obstruction brought about by the secondary user’s through a reestablishment hypothesis. Under the limitation of interference to primary user, the queuing theory is used to overcome this issue and to obtain the higher data rate of SU’s. finally, it is demonstrated that the cyclostationary detection method can be improved when extra channels are accessible.

The present paper is focused to evaluate the pressure drop and heat transfer performance of a double layer circular microchannel heat sink with numerically and experimentally. Numerical analysis is carried for various mass flow rates, with turbulent condition used in the ANSYS Fluent for two flow arrangements. The experiment is carried out by varying the mass flow rate ranges 3.32x10-4 kg/s to 27.72x10-4 kg/s with water as the cooling medium. The effect of a parallel flow and counter flow arrangements on heat transfer and flow parameters is studied for a constant heat input of 80W. The numerical result is nearly the same with the measured values. The pressure drop increases with the mass flow rate. The heat transfer enhancement is evaluated by the wall surface temperature and temperature uniformity. Even though parallel and counter flow arrangement has similar flow and thermal behavior, the latter has better temperature uniformity in the base of the heat sink for all pumping powers.

Authors: Syah Putri Githa , Nurlatifah Zakaria Myrna
Published: October 2019

Karies merupakan demineralisasi jaringan keras gigi yang diinisiasi oleh aktivitas mikrobial pada lapisan gigi. Salah satu tindakan untuk mencegah terjadinya karies adalah dengan penggunaan fluor sehingga terbentuk ikatan fluoroapatit pada gigi. Salah satu bahan alami yang mengandung konsentrasi fluor dan kalsium tinggi adalah, ikan teri (Stolephorus insularis), yang mengandung fluor sebanyak 15,7-38,3 ppm terutama dalam bentuk senyawa CaF2. Ikan teri sangat mudah ditemukan di Indonesia dan merupakan sumber fluor dan kalsium alami yang sangat baik, namun pembahasan mengenai potensi ikan teri untuk mencegah gigi berlubang masih sangat minim. Artikel ini merupakan ulasan telaah pustaka yang membahas mengenai potensi ikan teri untuk pencegahan gigi berlubang dari berbagai sumber literatur imiah dan penelitan ilmiah. Kandungan fluor dan kalsium pada ikan teri sangat tinggi, konsumsi ikan teri sebanyak 50 gram setiap hari dapat dimanfaatkan untuk mengoptimalkan pertumbuhan tulang dan mencegah gigi berlubang. Ikan teri dapat dikonsumsi langsung dengan diolah menjadi berbagai jenis makanan, bahan aktif dalam pasta gigi dan obat kumur, atau diolah menjadi krim dan gel sebagai fluor yang diaplikasikan secara topikal. Ikan teri merupakan sumber daya alam Indonesia yang melimpah dengan kandungan fluor dan kalsium yang tinggi. Bahan ini relatif murah dan mudah didapat. Sosialisasi mengenai kebaikan ikan teri dan studi lebih lanjut mengenaik pengolahan ikan teri sebaiknya terus dilakukan. Melihat potensi yang baik dari ikan teri, diharapkan bahan ini dapat menjadi salah satu alternatif untuk meningkatkan pencegahan gigi berlubang di masyarakat.

Authors: Hartaty Hartaty , Menga Maria Kurni
Published: October 2019

Immunization is giving the body immunity to a disease by putting something in the body so that the body is resistant to diseases that are endemic or dangerous to someone. Immunization comes from the word immune, which means immune or resistant. This needs special attention from health workers because with a good level of knowledge will help reduce mortality in infants not being immunized. Purpose of this research was to know the description of your mother's level of knowledge about infant immunization. Researchers used descriptive research. The sampling technique uses the accidental sampling method where the sample is all those who happen to come to work at the Batua Makassar Public Health Center at the time of the study. The method of collecting data is based on the willingness of the subjekts by filling out statements and signing the consent form to be subjekts and filling in the questionnaire based on the time and place agreed by the subjekts then presented in the data tabulation. This research showed that of 40 subjekts, 25 subjekts (62.5%) had sufficient knowledge in the category, 8 subjekts (20%) had knowledge in the good category and 7 subjekts (17.5%) in the knowledge category were lacking. Therefore, the important role of nurses to do promotive and preventive efforts on matters relating to immunization programs for infants and can provide more information to the public so that people know more about immunization.
Labor Market Migrations: Immigrant Intersections in the Informal Economy
Authors: Kim Anna
Published: October 2019

This study argues that many workers in Asian enclave economies move between both formal and informal employment. Scholars and other commentators have often framed “immigrant work,” as static, exploitative, and characterized by illegal arrangements, while formal employment has provided mobility, better pay, and important fringe benefits, including health care and paid vacations. The relationship between formal and informal labor markets, however, may be more intertwined in an ethnic enclave economy. Drawn from the experiences of Korean and Latino immigrant workers from Los Angeles’ Koreatown, the qualitative data presented here show that many workers move back and forth in a “blended” or “mixed” labor market, in a pattern that complicates conventional understandings of the working lives of immigrant laborers.

Rights at Risk: South Asians in the Post-9/11 United States
Authors: Mishra Sangay
Published: October 2019

South Asian Americans, one of the fastest-growing and most diverse immigrant communities, have experienced increased discrimination and hate crime during the post-9/11 period. South Asians bore the brunt of racial hostility triggered in the immediate aftermath of the attacks, with Muslims and Sikhs bearing the greatest burden. The domestic security policies inaugurated after 2001 further impacted both South Asian and Arab communities adversely. These official policies ranging from surveillance of mosques and communities to delayed naturalization and restricted immigration have severely encroached upon the civil liberties of the groups. The ten-year anniversary of the 9/11 attacks should be an occasion to review some of these policies in order to ensure that South Asian and Arab communities are not being profiled and targeted in the name of domestic security.
An Agenda for Policy Change: Participatory Research and Data Collection by Southeast Asian Youth
Authors: Ishihara Kohei
Published: October 2019

In a policy-making world that is influenced by “model minority” ideology and racial aggregate data, Southeast Asian Americans have become one of the most underrepresented and misunderstood Asian American communities. Cambodian, Laotian, and Hmong youth leaders in Providence, Rhode Island, protested this lack of representation by surveying 16 percent of the city’s Southeast Asian youth population. This data became the first of its kind to provide a quantitative and qualitative portrait of the lives and issues experienced by the city’s Southeast Asian residents. Youth leaders were trained in survey administration and data analysis in order to design and execute the survey. Survey results revealed the very intricate and oppressive realities faced by Southeast Asian youth, including lack of education, gang violence, racial profiling, inter-generational conflict, as well cultural conflict over ideas of gender and sexuality. Youth leaders used the data and a process of consensus decision making to develop a list of policy-change recommendations targeting Rhode Island decision makers and power brokers.

Quality school is the dream of all parties. High-quality schools are characterized by the management of professional schools, learning activities that run in an innovative, creative and fun way, and can achieve the curriculum targets and optimal absorption, then the learning outcomes show good quality. Quality management of educational resources, especially human resources, curriculum, educational and financial facilities and infrastructure is the most decisive factor in the realization of quality schools. Therefore, managerial capabilities of organizers and school managers largely determine the diversity of school quality. Modern societies term the diversity of school quality as “elite school” which means large, luxurious, and quality or the term “school alit” means small, simple, and lacking in quality. However, what really distinguishes school quality lies in the ability of school administrators and managers to manage or manage the school. Small schools that are professionally managed with quality based, the results will be large and quality schools.

Authors: Humaidi Humaidi , Fatmawati Kirana
Published: October 2019

The case of child neglect is one of the main problems that is a challenge for the Indonesian people. Many parents deliberately leave their children in public places or in hospitals. One of the reasons is because the economic, social, family, or child factors are born with disabilities. So the parents do not want to take care of the child. To overcome this problem, the Jakarta Sayap Ibu Foundation is not only available to accommodate, care for and nurture the children of the Foundation but also foster their character through religious activities and ethics education. With this coaching, they can be virtuous, polite, and responsible, and can be useful people. In carrying out coaching, the method used is through habituation, disciplinary methods and storytelling methods. Based on the results of research conducted shows that the Jakarta Wings Mother Foundation has succeeded in educating and building their character into humans with religious characters. Fostering children's character through religious values is considered more effective than without religious values. This research is a type of qualitative field research, using the method of description-inductive and philosophical-analysis. In collecting data, researchers used observation, documentation and interview techniques.

In search of visible-light photoresponsive peptide nucleic acids (PNAs) for reversible control of DNA hybridization
Authors: Zhang Lei , Linden Greta , Vázquez Olalla
Published: October 2019

Photoswitchable oligonucleotides can determine specific biological outcomes by light-induced conformational changes. In particular, artificial probes activated by visible-light irradiation are highly desired in biological applications. Here, we report two novel types of visible-light photoswitchable peptide nucleic acids (PNAs) based on the molecular transducers: hemithioindigo and tetra-ortho-fluoroazobenzene. Our study reveals that the tetra-ortho-fluoroazobenzene–PNA conjugates have promising properties (fast reversible isomerization, exceptional thermal stability, high isomer conversions and sensitivity to visible-light irradiation) as reversible modulators to control oligonucleotide hybridization in biological contexts. Furthermore, we verified that this switchable modification delivers a slightly different hybridization behavior in the PNA. Thus, both melting experiments and strand-displacement assays showed that in all the cases the trans-isomer is the one with superior binding affinities. Alternative versions, inspired by our first compounds here reported, may find applications in different fields such as chemical biology, nanotechnology and materials science.

MAXI J1621–501 is the first Swift/XRT Deep Galactic Plane Survey transient that was followed up with a multitude of space missions (NuSTAR, Swift, Chandra, NICER, INTEGRAL, and MAXI) and ground-based observatories (Gemini, IRSF, and ATCA). The source was discovered with MAXI on 2017 October 19 as a new, unidentified transient. Further observations with NuSTAR revealed two Type I X-ray bursts, identifying MAXI J1621–501 as a low mass x-ray binary with a neutron star primary. Overall, 24 Type I bursts were detected from the source during a 15 month period. At energies below 10 keV, the source spectrum was best fit with three components: an absorbed blackbody with kT = 2.3 keV, a cutoff power law with index Γ = 0.7, and an emission line centered on 6.3 keV. Timing analysis of the X-ray persistent emission and burst data has not revealed coherent pulsations from the source or an orbital period. We identified, however, a super-orbital period ∼78 days in the source X-ray light curve. This period agrees very well with the theoretically predicted radiative precession period of ∼82 days. Thus, MAXI J1621–501 joins a small group of sources characterized with super-orbital periods.

Weak lensing peak abundance analyses have been applied in different surveys and demonstrated to be a powerful statistic in extracting cosmological information complementary to cosmic shear two-point correlation studies. Future large surveys with high number densities of galaxies will enable tomographic peak analyses. Focusing on high peaks, we investigate quantitatively how the tomographic redshift binning can enhance the cosmological gains. We also perform detailed studies about the degradation of cosmological information due to photometric redshift (photo-z) errors. We show that for surveys with a number density of galaxies of ∼40 arcmin−2, a median redshift of ∼1, and a survey area of ∼15,000 deg2, the four-bin tomographic peak analyses can reduce the error contours of (Ωm, σ
8) by a factor of 5 compared to 2D peak analyses in the ideal case of the photo-z error being absent. More redshift bins can hardly lead to significantly better constraints. The photo-z error model here is parameterized by z
bias and σ
ph and the fiducial values of z
bias = 0.003 and σ
ph = 0.02 are taken. We find that using tomographic peak analyses can constrain the photo-z errors simultaneously with cosmological parameters. For four-bin analyses, we can obtain σ(z
bias)/z
bias ∼ 10% and σ(σ
ph)/σ
ph ∼ 5% without assuming priors on them. Accordingly, the cosmological constraints on Ωm and σ
8 degrade by factors of ∼2.2 and ∼1.8, respectively, with respect to zero uncertainties on photo-z parameters. We find that the uncertainty of z
bias plays a more significant role in degrading the cosmological constraints than that of σ
ph.
The Role of Clathrate Formation in Europa’s Ocean Composition

Published: October 2019

We use a thermodynamic statistical model to evaluate how the composition of Europa’s internal ocean may have been affected by clathrate hydrate formation. Assuming an input of the observed O2 and CO2 from the surface into a mildly acidic ocean (pH < 6), and considering the possibility of contributions by reduced (with CH4 and H2S) or oxidized (CO2-bearing) hydrothermal fluids, we calculate the fractional occupancies in clathrate and deduce the effect on the ocean’s composition. The structure of the clathrate formed, and therefore its density and composition is influenced by the relative amount of O2 compared to the other compounds present. We also include a mixture of noble gases—argon, krypton, and xenon—based on cometary abundances measured at comet 67P and find that the Ar/Kr ratio can be affected by almost two orders of magnitude. In most cases, the formed clathrate is likely to become part of the icy crust, with guest molecules possibly accessible to future in situ measurements by the Europa Clipper and JUICE missions.

HaloSat is a small satellite (CubeSat) designed to map soft X-ray oxygen line emission across the sky in order to constrain the mass and spatial distribution of hot gas in the Milky Way. The goal of HaloSat is to help determine if hot gas gravitationally bound to individual galaxies makes a significant contribution to the cosmological baryon budget. HaloSat was deployed from the International Space Station in 2018 July and began routine science operations in 2018 October. We describe the goals and design of the mission, the on-orbit performance of the science instrument, and initial observations.
Effect of Ionization and Recombination on the Evolution of the Harris-type Current Sheet in Partially Ionized Plasmas

Published: October 2019

Two-dimensional magnetohydrodynamics (MHD) simulations, treating plasma and neutral populations (hereafter, neutrals) as two separate components of the magneto-fluid, are performed in order to investigate the effect of ionization and recombination (or I/R) on the time evolution of the Harris-type current sheet in partially ionized plasmas. Our MHD simulations, including the effect of ambipolar diffusion (arising due to ion-neutral interactions) along with the I/R, show that the current sheet thinning occurs due to the diffusion of neutral particles from the current sheet. In addition to ambipolar diffusion, frictional heating also appears and affects the evolution of the current sheet. In a current sheet that is formed in a partially ionized plasma, the neutral population tries to spread outward and the plasma population tries to converge toward the center of the current sheet, and the overall process is influenced by the I/R. One of the important feature that is captured in our 2D simulations is that the escape of neutrals from the current sheet is sometimes suppressed due to the increase in ionization rate at the center of the current sheet, for the case of collisional I/R. As long as the ionization degree is kept low inside the current sheet, the current sheet thinning and elongation takes place and the current sheet becomes unstable due to the tearing-mode and plasmoid formation. The ion-neutral interactions coupled with I/R and the dynamics of the magnetic reconnection play an important role in plasmoid-mediated reconnection, therefore, the present study on the current sheet thinning and plasmoid formation could serve as a key for understanding bursty and intermittent plasma ejections observed in the solar chromosphere.

We perform a high-cadence transient survey with the Subaru Hyper Suprime-Cam (HSC), which we call the Subaru HSC survey Optimized for Optical Transients (SHOOT). We conduct HSC imaging observations with time intervals of about one hour on two successive nights, and spectroscopic and photometric follow-up observations. A rapidly declining blue transient SHOOT14di at z = 0.4229 is found in observations on two successive nights using an image-subtraction technique. The rate of brightness change is

) in the observer (rest) frame and the rest-frame color between 3400 and 4400 Å is

. The nature of the object is investigated by comparing its peak luminosity, decline rate, and color with those of transients and variables previously observed, and with those of theoretical models. None of the transients or variables share the same properties as SHOOT14di. Comparisons with theoretical models demonstrate that, while the emission from the cooling envelope of a SN IIb shows a slower decline rate than SHOOT14di, and the explosion of a red supergiant star with a dense circumstellar wind shows a redder color than SHOOT14di, the shock breakout at the stellar surface of the explosion of a

red supergiant star with a small explosion energy of

erg reproduces the multicolor light curve of SHOOT14di. This discovery shows that a high-cadence, multicolor optical transient survey at intervals of about one hour, and continuous and immediate follow-up observations, is important for studies of normal core-collapse supernovae at high redshifts.

Coronal mass ejections (CMEs) play a decisive role in driving space weather, especially the fast ones (e.g., with speeds above 800 km s−1). Understanding the trigger mechanisms of fast CMEs can help us gain important information in forecasting them. The filament eruptions accompanied with CMEs provide a good tracer in studying the early evolution of CMEs. Here we surveyed 66 filament-accompanied fast CMEs to analyze the correlation between the trigger mechanisms, namely either magnetic reconnection or ideal MHD process, associated flares, and CME speeds. Based on the data gathered from SDO, GONG, and STEREO, we find that (1) active region (AR) filament and intermediate filament (IF) eruptions show a higher probability for producing fast CMEs than quiet Sun (QS) filaments, while the probability of polar crown (PC) filament eruptions is zero in our statistic; (2) AR filament eruptions that produce fast CMEs are more likely to be triggered by magnetic reconnection, while QS filaments and IFs are more likely to be triggered by an ideal MHD process; (3) for AR filaments and IFs, it seems that the specific trigger mechanism does not have a significant influence on the resulting CME speeds, while for the QS filaments, the ideal MHD mechanism can more likely generate a faster CME; (4) comparing with previous statistical studies, the onset heights of filament eruptions and the decay indexes of the overlying field show some differences: for AR filaments and IFs, the decay indexes are larger and much closer to the theoretical threshold, while for QS filaments, the onset heights are higher than those obtained in previous results.

We explore electron preacceleration at high-Mach-number nonrelativistic perpendicular shocks at, e.g., young supernova remnants, which are a prerequisite of further acceleration to very high energies via diffusive shock acceleration. Using fully kinetic particle-in-cell simulations of shocks and electron dynamics in them, we investigate the influence of shock-surfing acceleration (SSA) at the shock foot on the nonthermal population of electrons downstream of the shock. The SSA is followed by further energization at the shock ramp where the Weibel instability spawns a type of second-order Fermi acceleration. The combination of these two processes leads to the formation of a nonthermal electron population, but the importance of SSA becomes smaller for larger ion-to-electron mass ratios in the simulation. We discuss the resulting electron spectra and the relevance of our results to the physics of systems with real ion-to-electron mass ratios and fully three-dimensional behavior.
