The making of "Montenegrin language": nationalism, language planning, and language ideology after the collapse of Yugoslavia (1992-2011)
The paper discusses the political process of standardization of the Montenegrin language and its effect on the ethnic differentiation in post-Yugoslav Montenegro. The standardization of the Montenegrin language, which was started by a handful of linguists, eventually became a national project after the independence of Montenegro. This process did not lead to a drastic change of the language; however, it formed and expanded ethnic cleavages in Montenegro

Discovery of Diffuse Radio Source in Abell 1060
Non-thermal components in the intra-cluster medium (ICM) such as turbulence,
magnetic field, and cosmic rays imprint the past and current energetic
activities of jets from active galactic neuclie (AGN) of member galaxies as
well as disturbance caused by galaxy cluster mergers. Meter- and
centimeter-radio observations of synchrotron radiation allow us to diagnose the
nonthermal component. Here we report on our discovery of an unidentified
diffuse radio source, named the Flying Fox, near the center of the Abell 1060
field. The Flying Fox has an elongated ring-like structure and a central bar
shape, but there is no obvious host galaxy. The average spectral index of the
Flying Fox is -1.4, which is steeper than those for radio sources seen at meter
wavelength. We discussed the possibilities of radio lobes, phoenixes, radio
halos and relics, and Odd Radio Circle (ORC). In conclusion, the Flying Fox is
not clearly explained by known radio sources.Comment: 6 pages, 3 figures, Submitted to PASJ as Lette
Suzaku and XMM-Newton Observations of the Fornax cluster: Temperature and Metallicity Distribution
Suzaku observed a central region and five offset regions within 0.2 r180 in
the Fornax cluster, a nearby poor cluster, and XMM-Newton mapped the cluster
with 15 pointings out to 0.3 r180. The distributions of O, Mg, Si, S, and Fe in
the intracluster medium (ICM) were studied with Suzaku, and those of Fe and
temperature were studied with XMM. The temperature of the ICM gradually
decreases with radius from 1.3 keV at 0.04 r180 to 1 keV at 0.2-0.3 r180. If
the new solar abundances of Lodders et al. (2003) and a single-temperature
plasma model are adopted, O, Mg, Si, S, and Fe show similar abundances: 0.4-0.6
solar within 0.02-0.2 r180. This Fe abundance is similar to those at 0.1-0.2
r180 in rich clusters and other groups of galaxies. At 0.2-0.3 r180, the Fe
abundance becomes 0.2-0.3 solar. A two-temperature plasma model yields ICM
abundances that are higher by a factor of 1.2-1.5, but gives similar abundance
ratios among O, Mg, Si, S, and Fe. The northern region has a lower ICM
temperature and higher brightness and Fe abundance, whereas the southern region
has a higher ICM temperature and lower brightness and Fe abundance. These
results indicate that the cD galaxy may have traveled from the north because of
recent dynamical evolution. The cumulative oxygen- and iron-mass-to-light
ratios within 0.3 r180 are more than an order of magnitude lower than those of
rich clusters and some relaxed groups of galaxies. Past dynamical evolution
might have hindered the strong concentration of hot gas in the Fornax cluster's
central region. Scatter in the IMLR and similarity in the element abundances in
the ICM of groups and clusters of galaxies indicate early metal synthesis.Comment: 15 pages, 13 figures, accepted for publication in PAS
Regional contributions through athletic lessons for elementary school children
We have provided athletic lessons for elementary school children for four years. These lessons are at the center of a project that aims to contribute to the local community. Initially, we decided on the following theme: “Have fun, learn to run fast, and stand on the Big Swan track.” To improve children’s competitive abilities, we focused on engaging them in fun activities that would lay the foundation for a life filled with sports; to motivate and engage the children, we gave them a chance to attend track meets as part of the program. This project has great potential, both as a practical approach to Track and Field instruction and as a basis for student volunteer activities in the elementary school teaching course. We believe that faculty members and students of Niigata University of Health and Welfare will be able to connect with many more children in the region through this project
Pseudogap formation in organic superconductors
The condensation of paired fermions into superfluid states changes
progressively depending on the coupling strength. At the midpoint of the
crossover between Bardeen--Cooper--Schrieffer (BCS) weak-coupling and
Bose--Einstein condensate (BEC) strong-coupling limits, paired fermions
condensate most robustly, thereby leading to the emergence of a pseudogap due
to enhanced pairing fluctuations. In the case of electrons in solids,
excessively strong interactions often induce competing electronic orders
instead of strong-coupling superconductivity, and experimental comprehension of
the pseudogap remains incomplete. In this study, we provide experimental
evidence demonstrating the opening of a pseudogap, marking the incipient stage
of the BCS-BEC crossover in the organic system -(BEDT-TTF). By
controlling electron correlations, we investigate the thermodynamic properties
of the BCS-BEC crossover and pseudogap phase. Since the superconductivity of
-(BEDT-TTF) arises from a simple Fermi liquid that does not
exhibit any other electronic orders, our study shed light on the inherent
nature of the BCS-BEC crossover
Suzaku observations of the Hydra A cluster out to the virial radius
We report Suzaku observations of the northern half of the Hydra A cluster out
to ~1.4 Mpc, reaching the virial radius. This is the first Suzaku observations
of a medium-size (kT ~3 keV) cluster out to the virial radius. Two observations
were conducted, north-west and north-east offsets, which continue in a filament
direction and a void direction of the large-scale structure of the Universe,
respectively. The X-ray emission and distribution of galaxies elongate in the
filament direction. The temperature profiles in the two directions are mostly
consistent with each other within the error bars and drop to 1.5 keV at 1.5
r_500. As observed by Suzaku in hot clusters, the entropy profile becomes
flatter beyond r_500, in disagreement with the r^1.1 relationship that is
expected from accretion shock heating models. When scaled with the average
intracluster medium (ICM) temperature, the entropy profiles of clusters
observed with Suzaku are universal and do not depend on system mass. The
hydrostatic mass values in the void and filament directions are in good
agreement, and the Navarro, Frenk, and White universal mass profile represents
the hydrostatic mass distribution up to ~ 2 r_500. Beyond r_500, the ratio of
gas mass to hydrostatic mass exceeds the result of the Wilkinson microwave
anisotropy probe, and at r_100, these ratios in the filament and void
directions reach 0.4 and 0.3, respectively. We discuss possible deviations from
hydrostatic equilibrium at cluster outskirts. We derived radial profiles of the
gasmass- to-light ratio and iron-mass-to-light ratio out to the virial radius.
Within r_500, the iron-mass-to-light ratio of the Hydra A cluster was compared
with those in other clusters observed with Suzaku.Comment: 16 pages, 15 figures; Accepted for publication in PAS
