Empiryczna weryfikacja Kołowego Modelu Motywów Ja
Authors: Stolarski Mikołaj 
Published: March 2021

Motywy ja stanowią przedmiot dociekań psychologicznych od wielu lat, natomiast samo pojęcie jest stosunkowo nowe. Przedstawiony artykuł zawiera empiryczną weryfikację Kołowego Modelu Motywów Ja bazującego na personalistycznej koncepcji osobowości zaproponowanej przez H. Gasiula. Autor ten bazując na efektach poszukiwania istotnych źródeł ludzkiej motywacji uzasadniał w swoich analizach, że najbardziej istotne są te motywy, które wynikają z osobowej natury człowieka, a w szczególności z jej atrybutów. Opracowany przez H. Gasiula i W. Strusa model 12 Motywów Ja jest efektem uwzględnienia różnych kategorii atrybutów osobowych oraz rodzajów Motywów Ja wskazywanych na podstawie różnych empirycznych badań psychologicznych. Uzyskane dane w istotnej mierze potwierdzają trafność Kołowego Modelu Motywów Ja i mogą również stanowić o zasadności ich hierarchicznego uporządkowania.

Abstract
Research using X-ray diffraction (XRD) remains to be accelerated in spite of its importance in materials science. Automated noise separation or optimization of measurement time in XRD is beneficial for discovering materials. This study analyzes two-dimensional XRD (2D-XRD) with density-based clustering to accelerate XRD. This clustering technique can separate diffraction pattern signals from noises, even with low signal-to-noise ratio (S/N) 2D-XRD. Moreover, we found that the crystalline degree information in composition spreads is captured based on density. This information requires a long time to be captured with conventional one-dimensional detectors or scintillation counters. Therefore, these findings lead to dramatic reduction and optimization of measurement time to improve S/N. The proposed procedure is applicable with 2D detector measurements.

Abstract
High-photoresponsivity BaSi2 films is of great importance for solar cell applications. The photoresponsivity was enhanced greatly in C-doped BaSi2 films formed by sputtering BaSi2 and SiC or C targets. The shift of Raman peak and optical absorption edge with increasing C concentration (n
C) showed that more C atoms were incorporated in BaSi2 films when the SiC target was sputtered. When n
C was 6 × 1020 cm−3 by the SiC target, the photoresponsivity approached 2 A W−1 under a bias voltage of 0.1 V between the top and bottom electrodes. This is the highest value ever reported for BaSi2 films.

Published: March 2021

Abstract
Burgers vectors b of threading dislocations in freestanding GaN substrates were identified through statistical classification using the etch pit and multiphoton-excitation photoluminescence methods. The b = 1a + 1c threading mixed dislocations were propagated with large inclination angles more than four degrees from the c-axis to minimize elastic strain energy. The b = 1c threading edge dislocations had a large contrast difference of more than 0.4 in the photoluminescence image due to their strong nonradiative properties. Based on these characteristics obtained through multiphoton-excitation photoluminescence measurements, major types of dislocations (b = 1a, 1a + 1c, 1c) could statistically be identified.

Abstract
Optical wireless power transmission systems incorporating photovoltaic cells and lasers are expected to serve as next-generation energy supply devices for automobiles and autonomous underwater vehicles. High photoelectric conversion efficiencies over 40% of photovoltaic converters under high-power irradiation over 10 W cm−2 are required for the practical application in these applications. We achieved a high conversion efficiency of 43.0% of GaInP photonic power converter under high-power 638 nm laser irradiation of 17.0 W cm−2 by incorporating multi-crossed finger electrodes and a distributed Bragg reflector. The highest efficiency, 46.0% of GaInP converter cell, was also obtained at 1.1 W cm−2 laser irradiation.

Latar Belakang: Jumlah CD4 merupakan parameter penting pada penderita HIV dan berhubungan dengan peningkatan risiko disfungsi sistolik. Hingga saat ini, korelasi antara jumlah CD4 dengan parameter global longitudinal strain (GLS) sebagai indikator fungsi sistolik subklinis masih belum jelas.
Metode: Penelitian ini merupakan studi observasional dengan metode belah lintang. GLS ventrikel kiri diperiksa menggunakan ekokardiografi dua dimensi. Jumlah CD4 baseline dan nadir diperoleh dari rekam medis sedangkan jumlah CD4 aktual dan CD4 percentage (CD4%) diperiksa menggunakan metode flow cytometry.
Hasil: Total 37 pasien HIV asimptomatik mengikuti penelitian dengan rerata umur 31,95± 7,54 tahun dan median durasi penggunaan ARV adalah 34 bulan. Median CD4 baseline dan CD4 nadir adalah 272 sel/uL dan 223 sel/uL, sedangkan rerata CD4 aktual dan CD4% adalah 516,08±252,03 sel/uL dan 19,66±7,97 %. Semua subyek penelitian memiliki fungsi sistolik normal. Rerata GLS ventrikel kiri adalah 17,02±0,71. GLS ventrikel kiri berkorelasi positif dengan CD4 aktual (r=0,43; p=0,008) dan CD4% (r=0,349; p=0,034). Penderita HIV dengan jumlah CD4 aktual ?400 sel/uL memiliki GLS ventrikel kiri yang lebih baik dibandingkan dengan yang <400 sel/uL (p=0,022).
Kesimpulan: Jumlah CD4, terutama CD4 aktual dan CD4 percentage berkorelasi dengan disfungsi sistolik subklinis yang diukur dengan global longitudinal strain pada penderita HIV asimtomatik. Hal ini mungkin dapat menjelaskan peran CD4 terhadap patogenesis gagal jantung pada penderita HIV.
Effect Of Topical DLBS 1425 On Tissue Plasminogen Activator (tPA) Expression In Trabecular Meshwork Of Wistar Rats
Authors: Widijanto Utami , Nugroho Trilaksana , Cahyono Maharani 
Published: March 2021

Introduction: Tissue plasminogen activator (tPA) in the trabecular meshwork (TM) is a serine protease that important to maintain the aquos outflow resistance by activating the matrix metalloproteinase (MMP). It can cause a degradation of the extracellular matrix, which can maintain the normal flow of aquos humor. However, the use of anti-inflammatory drugs has been shown to reduce the expression of tPA, leading to an increase in the outflow resistance. Therefore, we propose the use of DLBS 1425, an extract of Phaleria macrocarpa which has been proven to have anti-inflammatory effects.
Aim : This study aims to determine the expression of tPA in Wistar rats’ TM.
Methods : An experimental laboratory study with post-test only randomized controlled group design was performed. Twenty-two Wistar rats were divided into two groups, the control and the experimental. The experimental group was given topical DLBS 1425 at a dose of 6 times / day, for 4 weeks. The control group was given drops of Hyalub Minidose® 6 times / day, for 4 weeks. tPA expression on TM was examined by immunohistochemical staining. Data were collected and processed using the SPSS 15.0 for Windows.
Results : The mean tPA expression in TM with Allred scores in the experimental group (0.18 ± 0.60) was significantly lower (p <0.001) than the control group (6.27 ± 0.91).
Conclusion : Topical DLBS 1425 suppresses the expression of tPA on the trabecular meshwork of Wistar rats.
Key words: tissue plasminogen activator, trabecular meshwork, DLBS 1425, Phaleria macrocarpa.

Published: March 2021

Tulisan ini membahas tentang Adat Jujuran dalam Perkawinan Dayak Meratus di Desa Kadayang Kalimantan Selatan. Dimana dalam pelaksanaan upacara perkawinan sering mengalami kegagalan yang diakibatkan oleh jumlah jujuran yang diminta terlalu besar sehingga menyebabkan pihak laki-laki tidak sanggup untuk membayarnya dan memutuskan untuk membatalkan pernikahan bahkan tidak jarang lebih memilih menikah dengan orang yang berbeda keyakinan. Penelitian ini adalah penelitian deskriptif kualitatif dengan metode pengumpulan data melalui wawancara, dan dokumentasi. Hasil penelitian menunjukkan dalam proses perkawinan masyarakat Hindu Kadayang bentuk jujuran yang diserahkan kepada adat dan juga keluarga pengantin wanita berupa sejumlah uang, yang jumlahnya tidak mengikat, tetapi disesuaikan dengan kemampuan calon mempelai laki-laki. Besar kecilnya jumlah jujuran adalah hasil negosiasi yang terjadi pada acara Baruji. Makna yang terkandung dalam adat jujuran secara teologis bahwa perkawinan masyarakat Hindu desa Kadayang dikatakan sah apabila menggunakan adat jujuran yang harus disaksikan oleh adat dan disaksikan oleh Tuhan yang disimbolkan dengan penggunaan sirih, pinang dan kapur sebagai simbol Tuhan. Makna sosial kemasyarakatan dalam adat jujuran sebagai wujud penghargaan kepada orang tua calon mempelai perempuan dan ikatan yang menyatukan dua buah keluarga yang berbeda melalui pernikahan. Sanksi sosial keagamaan jika perkawinan dilaksanakan tanpa mengunakan adat jujuran maka perkawinan tersebut dianggap tidak sah secara agama.

Published: March 2021

Abstract
We present comprehensive characterization of the Galactic open cluster M 36. Some 200 member candidates, with an estimated contamination rate of ∼8%, have been identified on the basis of proper motion and parallax measured by the Gaia DR2. The cluster has a proper motion grouping around (

mas yr−1, and μ

δ
= − 3.35 ± 0.02 mas yr−1), distinctly separated from the field population. Most member candidates have parallax values 0.7–0.9 mas, with a median value of 0.82 ± 0.07 mas (distance ∼1.20 ± 0.13 kpc). The angular diameter of

determined from the radial density profile then corresponds to a linear extent of 9.42 ± 0.14 pc. With an estimated age of ∼15 Myr, M 36 is free of nebulosity. To the southwest of the cluster, we discover a highly obscured (A

V
up to ∼23 mag), compact (∼

) dense cloud, within which three young stellar objects in their infancy (ages ≲0.2 Myr) are identified. The molecular gas, 3.6 pc in extent, contains a total mass of (2–3) × 102
M
⊙, and has a uniform velocity continuity across the cloud, with a velocity range of −20 to −22 km s−1, consistent with the radial velocities of known star members. In addition, the cloud has a derived kinematic distance marginally in agreement with that of the star cluster. If physical association between M 36 and the young stellar population can be unambiguously established, this manifests a convincing example of prolonged star formation activity spanning up to tens of Myr in molecular clouds.
Self-gravitating Equilibria of Non-minimally Coupled Dark Matter Halos
Authors: Gandolfi Giovanni , Lapi Andrea , Liberati Stefano 
Published: March 2021

Abstract
We investigate self-gravitating equilibria of halos constituted by dark matter (DM) non-minimally coupled to gravity. In particular, we consider a theoretically motivated non-minimal coupling that may arise when the averaging/coherence length L associated with the fluid description of the DM collective behavior is comparable to the local curvature scale. In the Newtonian limit, such a non-minimal coupling amounts to a modification of the Poisson equation by a term L

relating the DM dynamical pressure p to density ρ and radius r, as expected for phase-space density stratification during the gravitational assembly of halos in a cosmological context. We confirm previous findings that, in the absence of non-minimal coupling, the resulting density ρ(r) features a steep central cusp and an overall shape mirroring the outcomes of N-body simulations in the standard ΛCDM cosmology, as described by the classic Navarro–Frenk–White or Einasto profiles. Most importantly, we find that the non-minimal coupling causes the density distribution to develop an inner core and a shape that closely follows the Burkert profile out to several core scale radii. In fact, we highlight that the resulting mass distributions can fit, with an accuracy comparable to Burkert’s one, the coadded rotation curves of dwarf, DM-dominated galaxies. Finally, we show that non-minimally coupled DM halos are consistent with the observed scaling relation between the core radius r

Published: March 2021

Abstract
We present new X-ray and UV observations of the Wolf–Rayet + black hole (BH) binary system NGC 300 X-1 with the Chandra X-ray Observatory and the Hubble Space Telescope Cosmic Origins Spectrograph. When combined with archival X-ray observations, our X-ray and UV observations sample the entire binary orbit, providing clues to the system geometry and interaction between the BH accretion disk and the donor star wind. We measure a binary orbital period of 32.7921 ± 0.0003 hr, in agreement with previous studies, and perform phase-resolved spectroscopy using the X-ray data. The X-ray light curve reveals a deep eclipse, consistent with inclination angles of i = 60°–75°, and a pre-eclipse excess consistent with an accretion stream impacting the disk edge. We further measure radial velocity variations for several prominent far-UV spectral lines, most notably H ii
λ1640 and C iv
λ1550. We find that the He ii emission lines systematically lag the expected Wolf–Rayet star orbital motion by a phase difference of Δϕ ∼ 0.3, while C iv
λ1550 matches the phase of the anticipated radial velocity curve of the Wolf–Rayet donor. We assume the C iv
λ1550 emission line follows a sinusoidal radial velocity curve (semi-amplitude = 250 km s−1) and infer a BH mass of 17 ± 4 M
⊙. Our observations are consistent with the presence of a wind-Roche lobe overflow accretion disk, where an accretion stream forms from gravitationally focused wind material and impacts the edge of the BH accretion disk.
Thermodynamically Governed Interior Models of Uranus and Neptune
Authors: Bailey Elizabeth , Stevenson David J. 
Published: March 2021

Abstract
Interior models of Uranus and Neptune often assume discrete layers, but sharp interfaces are expected only if major constituents are immiscible. Diffuse interfaces could arise if accretion favored a central concentration of the least volatile constituents (also, incidentally, the most dense); compositional gradients arising in such a structure would likely inhibit convection. Currently, two lines of evidence suggest possible hydrogen–water immiscibility in ice giant interiors. The first arises from crude extrapolation of the experimental H2–H2O critical curve to ∼3 GPa. The data are obtained for an impure system containing silicates, though Uranus and Neptune could also be “dirty.” Current ab initio models disagree (Soubiran & Militzer 2015), though hydrogen and water are difficult to model from first-principles quantum mechanics with the necessary precision. The second argument for H2–H2O immiscibility in ice giants, outlined herein, invokes reasoning about the gravitational and magnetic fields. While consensus remains lacking, here we examine the immiscible case. Applying the resulting thermodynamic constraints, we find that Neptune models with envelopes containing a substantial water mole fraction, as much as

, potentially suggestive of fully demixed hydrogen and water. Enough gravitational potential energy would be available from gradual hydrogen–water demixing to supply Neptune’s present-day heat flow for roughly 10 solar system lifetimes. Hydrogen–water demixing could slow Neptune’s cooling rate by an order of magnitude; different hydrogen–water demixing states could account for the different heat flows of Uranus and Neptune.
