Why is L1 not easy to hear?
Authors: Mizuguchi Shinobu , Tateishi Koichi 
Published: March 2020

We naively believe that L1 is easier to hear than L2. Generally, this belief is correct, but not always. Japanese contrastive focus is more challenging to identify than English focus even for L1 speakers. To account for why Japanese is hard to perceive, we first conducted production and perception experiments, to understand linguistic mechanisms. We found that Japanese lacks a part of focus effects and is an acoustically weak language contra previous studies. English, on the other hand, is an acoustically strong language and uses the F0 feature as a focus cue. We then conducted an fMRI experiment to see whether or not linguistic mechanisms for them are implemented in the brain. We found that we employ different neural networks to process English and Japanese; the right dorsolateral frontal cortex is activated to process Japanese CF, but not English CF. Japanese is a pitch language and requires processing both lexical accents and pitch contours. English, on the other hand, needs to process lexical accent only, and it activates left superior temporal gyrus, insular, and supramargical regions, but not right dorsolateral frontal cortex. We conclude that processing burdens lead to perception difficulty, even for L1 Japanese speakers.
Closest conjunct agreement in replacives: Experimental evidence from Estonian
Authors: Kaps Marju 
Published: March 2020

The phenomenon of closest conjunct agreement (CCA) has been documented cross-linguistically in conjunctions (“X and Y”) and disjunctions (“(either) X or Y”), and agreement patterns with feature-mismatching coordination have been shown to be variable, both across constructions and speakers. The present work addresses agreement patterns with replacives subjects (“not X but Y”) in Estonian, where subjects can occur pre- or postverbally. Replacives differ from other forms of coordination by having a single asserted subject. A series of two speeded acceptability experiments with postverbal subject replacives, and a relative naturalness rating experiment comparing replacives to disjunctions showed that both CCA and a bias towards agreeing with the asserted subject (ASA) play a role in determiningverbal agreement with replacive subjects. Additionally, there is evidence for less featurally marked 3rd person verb forms being preferred, particularly when there are conflicting pressures on agreement from CCA and ASA, and for person mismatches being fully repaired by morphological syncretism.

Published: March 2020

Gear pump (pompa roda gigi) adalah jenis pompa positive displacement dimana fluida akan mengalir melalui celah-celah roda gigi dengan dinding rumahnya disebut sebagai pompa karena fluida yang dialirkan pada umumnya berupa cairan (liquid) atau bubur (slurry). Sedangkan pompa positive displacement berarti pompa tersebut menghisap sejumlah fluida yang terjebak yang kemudian ditekan dan dipindahkan ke arah keluaran (outlet). Gear pump sering digunakan untuk aplikasi hydrolic fluid power. Dalam pengoperasiannya sebuah komponen gear pump excavator dapat mengalami kegagalan, meskipun komponen tersebut masih dalam keadaan bagus/ baru. Untuk menganalisa penyebab terjadi kegagalan gear pump ini dilakukan pengujian yang meliputi pengujian yang bersifat merusak (destructive material testing) menggunakan uji kekerasan dan pengujian yang tidak merusak (non-destructive material testing) menggunakan uji fraktografi, metallografi dan pengujian komposisi kimia. Dari hasil pemeriksaan di labor menunjukan bahwa Gear Pump Excavator mengalami kerusakan pada gigi penggerak di bagian luar dan gigi bagian dalam, photo makro roda gigi bagian luar dalam penampang melintang menunjukan adanya cacat Deformasi / Perubahan Bentuk akibat beban bentur pada permukaan roda gigi. Roda gigi yang menerima beban putar/ gesek mengalami aus sesuai dengan arah putaran geardan pada permukaan patahan dan menunjukkan terdapatnya inklusi yang terkonsentrasi mengarah ke permukaan material gear pump excavator sehingga menyebabkan terjadinya aus. Pada material gear pump excavator yang mengalami kegagalan bila dilihat dari bentuk patahannya termasuk kepada jenis beban fatik karena sebelum patah gear pump excavator mengalami cacat deformasi.

ABSTRAK
Musim kemarau menjadi masalah utama bagi petani yang hanya mengandalkan suplai air melalui bendungan atau saluran irigasi. Air menjadi barang berharga dan menjadi rebutan. Namun masalah tersebut teratasi dengan adanya Pompa Air Tanpa Motor atau Hidram (Hydraulic Ram). Jenis pompa air ini sangatlah cocok untuk irigasi dan pengadaan air baku. Efisiensinya sangat tinggi karena pompa ini tidak tergantung kepada bahan bakar minyak, listrik ataupun oli mesin, hingga dapat beroperasi 24 jam terus menerus dan juga biaya operasionalnya bisa dikatakan sangat sedikit dan perawatan dan perbaikan sangat mudah, tidak memerlukan tenaga ahli khusus. Tujuan dalam penelitian ini adalah menganalisis ketersediaan air yang dibutuhkan untuk menggerakkan PATM, mengetahui tinjauan kinerja PATM, dan Mengetahui Kondisi PATM. Berdasarkan hasil penelitian debit air yang ada tidak mempengaruhi efisiensi PATM itu sendiri, debit yang diperoleh dalam beberapa tahun terakhir dengan jumlah rerata yang ada adalah 45,332 liter/detik dan untuk kebutuhan debit air pada PATM didapatkan hasil rerata 17,226/detik. PATM adalah teknologi pompa terbaru dengan menggunakan pemanfaatan gravitasi dimana akan menciptakan energi dari hantaman air yang menabrak faksi air lainnya untuk mendorong ke tempat yang lebih tinggi. Kondisi pompa saat ini telah mengalami kerusakan sebanyak 9 unit pompa, hal ini sangat berpengaruh terhadap kebutuhan air baku yang sering dimanfaatkan oleh masyarakat sekitarnya untuk kebutuhan lahan pertanian dan perkebunan.

Abstract
Small planets are common around late-M dwarfs and can be detected through highly precise photometry by the transit method. Planets orbiting nearby stars are particularly important as they are often the best-suited for future follow-up studies. We present observations of three nearby M dwarfs referred to as EIC-1, EIC-2, and EIC-3, and use them to search for transits and set limits on the presence of planets. On most nights our observations are sensitive to Earth-sized transiting planets, and photometric precision is similar to or better than TESS for faint late-M dwarfs of the same magnitude (I ≈ 15 mag). We present our photometry and transit search pipeline, which utilizes simple median detrending in combination with transit least-squares-based transit detection. For these targets, and transiting planets between one and two Earth radii, we achieve an average transit detection probability of ∼60% between periods of 0.5 and 2 days, ∼30% between 2 and 5 days, and ∼10% between 5 and 10 days. These sensitivities are conservative compared to visual searches.
A Second Look at 12 Candidate Dual AGNs Using BAYMAX

Published: March 2020

Abstract
We present an analysis of 12 optically selected dual active galactic nucleus (AGN) candidates at z < 0.34. Each candidate was originally identified via double-peaked [O iii] λ5007 emission lines and received follow-up Chandra and Hubble Space Telescope (HST) observations. Because the X-ray data are low-count (<100 counts) with small separations (<1″), a robust analysis is necessary for classifying each source. Pairing long-slit [O iii] observations with existing Chandra observations, we re-analyze the X-ray observations with Bayesian AnalYsis of AGNs in X-rays to determine whether the X-ray emission from each system is more likely a single or dual point source. We find that 4 of the 12 sources are likely dual X-ray point-source systems. We examine each point source’s spectra via a Monte Carlo method that probabilistically identifies the likely origin of each photon. When doing so, we find that (i) the secondary X-ray point sources in two of the systems have L
X < 1040 erg s−1, such that we cannot rule out a non-AGN origin, (ii) one source has a secondary with L
X > 1040 erg s−1 but a spectrum that is too soft to definitively preclude being X-ray emitting diffuse gas that was photoionized by the primary AGN, and (iii) one system (SDSS J1126+2944) is a dual AGN. Additionally, using complementary HST observations, we analyze a subsample of systems that are visually identified as merging. Our results suggest that dual AGNs may preferentially reside in mergers with small separations, consistent with both simulations and observations.
Stellar Density Profiles of Dwarf Spheroidal Galaxies
Authors: Moskowitz A. G. , Walker M. G. 
Published: March 2020

Abstract
We apply a flexible parametric model, a combination of generalized Plummer profiles, to infer the shapes of the stellar density profiles of the Milky Way’s satellite dwarf spheroidal galaxies (dSphs). We apply this model to 40 dSphs using star counts from the Sloan Digital Sky Survey, PanStarrs-1 Survey, Dark Energy Survey, and Dark Energy Camera Legacy Survey. Using mock data, we examine systematic errors associated with modeling assumptions and identify conditions under which our model can identify “non-standard” stellar density profiles that have central cusps and/or steepened outer slopes. Applying our model to real dwarf spheroidals, we do not find evidence for centrally cusped density profiles among the fifteen Milky Way satellites for which our tests with mock data indicate there would be sufficient detectability. We do detect steepened (with respect to a standard Plummer model) outer profiles in several dSphs—Fornax, Leo I, Leo II, and Reticulum II—which may point to distinct evolutionary pathways for these objects. However, the outer slope of the stellar density profile does not yet obviously correlate with other observed galaxy properties.
Detection of Echoes in PSR B1508+55 at Frequencies below 100 MHz Using the LWA1
Authors: Bansal K. , Taylor G. B. , Stovall Kevin , Dowell Jayce 
Published: March 2020

Abstract
PSR B1508+55 is known to have a single component profile above 300 MHz. However, when we study it at frequencies below 100 MHz using the first station of the Long Wavelength Array, it shows multiple components. These include the main pulse, a precursor, a postcursor, and a trailing component. The separation of the trailing component from the main peak evolves over the course of a three year study. This evolution is likely an effect of the pulse signal getting refracted off an ionized gas cloud (acting as a lens) leading to what appears to be a trailing component in the profile as the pulsar signal traverses the interstellar medium. Using this interpretation, we identify the location and electron density of the lens affecting the pulse profile.
A New Likely Redback Millisecond Pulsar Binary with a Massive Neutron Star: 4FGL J2333.1–5527

Abstract
We present the discovery of a likely new redback millisecond pulsar (MSP) binary associated with the Fermi γ-ray source 4FGL J2333.1–5527. Using optical photometric and spectroscopic observations from the Southern Astrophysical Research telescope, we identify a low-mass, main-sequence-like companion in a 6.9 hr, highly inclined orbit around a suspected massive neutron star primary. Archival XMM-Newton X-ray observations show this system has a hard power-law spectrum Γ = 1.6 ± 0.3 and L

X
∼ 5 × 1031 erg s−1, consistent with redback MSP binaries. Our data suggest that for secondary masses typical of redbacks, the mass of the neutron star is likely well in excess of ∼1.4 M
⊙, but future timing of the radio pulsar is necessary to bolster this tentative conclusion. This work shows that a bevy of nearby compact binaries still await discovery, and that unusually massive neutron stars continue to be common in redbacks.

Abstract
We present an investigation of the dependence of H2O maser detection rates and properties on the mid-IR active galactic nucleus (AGN) luminosity, L
AGN, and the obscuring column density, N
H, based on mid-IR and hard X-ray photometry. Based on spectral energy distribution fitting that allows for decomposition of the black hole accretion and star formation components in the mid-infrared, we show that the megamaser (disk maser) detection rate increases sharply for galaxies with 12 μm AGN luminosity

greater than 1042 erg s−1, from ≲3% (≲2%) to ∼12% (∼5%). By using the ratio of the observed X-ray to mid-IR AGN luminosity as an indicator of N
H, we also find that megamaser (disk maser) detection rates are boosted to 15% (7%) and 20% (9%) for galaxies with N
H ≥ 1023 cm−2 and N
H ≥ 1024 cm−2, respectively. Combining these column density cuts with a constraint for high

(≥1042 erg s−1) predicts further increases in the megamaser (disk maser) detection rates to 19% (8%) and 27% (14%), revealing unprecedented potential increases of the megamaser and disk maser detection rates by a factor of 7–15 relative to the current rates, depending on the chosen sample selection criteria. A noteworthy aspect of these new predictions is that the completeness rates are only compromised mildly, with the rates remaining at the level of ∼95%(∼50%) for sources with N
H ≥ 1023 cm−2 (N
H ≥ 1024 cm−2). Applying these selection methods to current X-ray AGN surveys predicts the detection of ≳15 new megamaser disks.
The Gravitational Instability of Adiabatic Filaments
Authors: Coughlin Eric R. , Nixon C. J. 
Published: March 2020

Abstract
Filamentary structures, or long and narrow streams of material, arise in many areas of astronomy. Here we investigate the stability of such filaments by performing an eigenmode analysis of adiabatic and polytropic fluid cylinders, which are the cylindrical analog of spherical polytropes. We show that these cylinders are gravitationally unstable to perturbations along the axis of the cylinder below a critical wavenumber k
crit ≃ few, where k
crit is measured relative to the radius of the cylinder. Below this critical wavenumber, perturbations grow as

, where τ is time relative to the sound-crossing time across the diameter of the cylinder, and we derive the growth rate σ
u as a function of wavenumber. We find that there is a maximum growth rate σ
max ∼ 1 that occurs at a specific wavenumber k
max ∼ 1, and we derive the growth rate σ
max and the wavenumbers k
max and k
crit for a range of adiabatic indices. To the extent that filamentary structures can be approximated as adiabatic and fluidlike, our results imply that these filaments are unstable without the need to appeal to magnetic fields or external media. Further, the objects that condense out of the instability of such filaments are separated by a preferred length scale, form over a preferred timescale, and possess a preferred mass scale.
