Statistical Properties of Soft X-Ray Emission of Solar Flares
Authors: Sadykov Viacheslav M , Kosovichev Alexander G , Kitiashvili Irina N , Frolov Alexander
Published: March 2019

We present a statistical analysis of properties of Soft X-Ray (SXR) emission, plasma temperature (T), and emission measure (EM), derived from Geostationary Operational Environmental Satellite observations of flares in 2002–2017. The temperature and EMs are obtained using the Temperature and EM-based Background Subtraction algorithm, which delivers reliable results together with uncertainties even for weak B-class flare events. More than 96% of flares demonstrate a sequential appearance of T, SXR, and EM maxima, in agreement with the expected behavior of the chromospheric evaporation process. The relative number of such flares increases with increasing the SXR flux maximum. The SXR maximum is closer in time to the T maximum for B-class flares than for ≥C-class flares, while it is very close to the EM maximum for M- and X-class flares. We define flares as “T-controlled” if the time interval between the SXR and T maxima is at least two times shorter than the interval between the EM and SXR maxima, and as “EM-controlled” if the time interval between the EM and SXR maxima is at least two times shorter than the interval between the SXR and T maxima. For any considered flare class range, the T-controlled events compared to EM-controlled events have: (a) higher EM but lower T; (b) longer durations and shorter relative growth times; and (c) longer FWHM and characteristic decay times. Interpretation of these statistical results based on analysis of a single loop dynamics suggests that for flares of the same class range, the T-controlled events can be developed in longer loops than the EM-controlled events.
MOSFIRE Spectroscopy of Quiescent Galaxies at 1.5 < z < 2.5. II. Star Formation Histories and Galaxy Quenching
Authors: Belli Sirio , Newman Andrew B. , Ellis Richard S.
Published: March 2019

We investigate the stellar populations for a sample of 24 quiescent galaxies at 1.5 < z < 2.5 using deep rest-frame optical spectra obtained with Keck MOSFIRE. By fitting templates simultaneously to the spectroscopic and photometric data and exploring a variety of star formation histories, we obtain robust measurements of median stellar ages and residual levels of star formation. After subtracting the stellar templates, the stacked spectrum reveals the Hα and [N ii] emission lines, providing an upper limit on the ongoing star formation rate of 0.9 ± 0.1

yr−1. By combining the MOSFIRE data with our sample of Keck LRIS spectra at lower redshift, we analyze the quiescent population at 1 < z < 2.5 in a consistent manner. We find a tight relation (with a scatter of 0.13 dex) between the stellar age and the rest-frame U − V and V − J colors, which can be used to estimate the age of quiescent galaxies, given their colors. Applying this age–color relation to large photometric samples, we are able to model the number density evolution for quiescent galaxies of various ages. We find evidence for two distinct quenching paths: a fast quenching that produces compact post-starburst systems and a slow quenching of larger galaxies. Fast quenching accounts for about a fifth of the growth of the red sequence at z ∼ 1.4 and half at z ∼ 2.2. We conclude that fast quenching is triggered by dramatic events, such as gas-rich mergers, while slow quenching is likely caused by a different physical mechanism.
Successful and Failed Flux Tube Emergence in the Solar Interior
Authors: Syntelis P. , Archontis V. , Hood A.
Published: March 2019

We report on our 3D magnetohydrodynamic simulations of cylindrical weakly twisted flux tubes emerging from 18 Mm below the photosphere. We perform a parametric study by varying the initial magnetic field strength (B
0), radius (R), twist (α), and length of the emerging part of the flux tube (λ) to investigate how these parameters affect the transfer of the magnetic field from the convection zone to the photosphere. We show that the efficiency of emergence at the photosphere (i.e., how strong the photospheric field will be in comparison to B
0) depends not only on B
0, but also on the morphology of the emerging field and on the twist. We show that parameters such as B
0 and magnetic flux alone cannot determine whether a flux tube will emerge to the solar surface. For instance, high-B
0 (weak-B
0) fields may fail (succeed) to emerge at the photosphere, depending on their geometrical properties. We also show that the photospheric magnetic field strength can vary greatly for flux tubes with the same B
0 but different geometric properties. Moreover, in some cases we have found scaling laws, whereby the magnetic field strength scales with the local density as B ∝ ρ

κ
, where κ ≈ 1 deeper in the convection zone and κ < 1 close to the photosphere. The transition between the two values occurs approximately when the local pressure scale (H

p
) becomes comparable to the diameter of the flux tube (H

p
 ≈ 2R). We derive forms to explain how and when these scaling laws appear and compare them with the numerical simulations.

We measure the expansion of the forward shock of the Small Magellanic Cloud supernova remnant 1E 0102.2–7219 in X-rays using Chandra X-Ray Observatory on-axis Advanced CCD Imaging Spectrometer observations from 1999 to 2016. We estimate an expansion rate of 0.025% ± 0.006% yr−1 and a blast wave velocity of

Assuming partial electron–ion equilibration via Coulomb collisions and cooling due to adiabatic expansion, this velocity implies a post-shock electron temperature of 0.84 ± 0.20 keV, which is consistent with the estimate of 0.68 ± 0.05 keV based on the X-ray spectral analysis. We combine the expansion rate with the blast wave and reverse shock radii to generate a grid of one-dimensional models for a range of ejecta masses (

Four notable additions to the South African echinoid fauna (Echinodermata, Echinoidea)
Authors: Filander Zoleka , Samyn Yves , Griffiths Charles
Published: March 2019

Although a comprehensive guide to the South African echinoid fauna was published as recently as 2017, four notable additions to the fauna have emerged since that time and are reported on here. The first South African records for Histocidarispurpurata (Thomson, 1872), Echinothrixdiadema (Linnaeus, 1758), Microcyphusrousseaui L. Agassiz, in Agassiz and Desor 1846, and Pseudoboletiamaculata Troschel, 1869 are presented. All four species have previously been recorded from the Atlantic and/or Indian Oceans and their ranges are thus extended southwards here. These additions increase the total number of echinoid species known from South Africa to 74.
Review of the genus Strumigenys (Hymenoptera, Formicidae, Myrmicinae) in Hong Kong with the description of three new species and the addition of five native and four introduced species records
Authors: Tang Kit Lam , Pierce Mac P. , Guénard Benoit
Published: March 2019

The species of the ant genusStrumigenysSmith, 1860 found in Hong Kong are reviewed based on new sampling efforts performed over the past five years (2014–2018). Prior to this, 12Strumigenysspecies had been recorded from Hong Kong, all confirmed here. Moreover, we add to this list three newly described species:S.hirsutasp. n.,S.lantauisp. n., andS.nathistorisocsp. n., and describe for the first time the worker caste ofS.formosaTerayama, Lin & Wu, 1995. We report new records for nine additional species, bringing the total number of species to 24, including four newly recorded species (S.hexameraBrown, 1958,S.membraniferaEmery, 1869,S.nepalensisBaroni Urbani and De Andrade, 1994, andS.rogeriEmery, 1890) which are considered to be introduced to Hong Kong. A global review of the introducedStrumigenysspecies is presented. The taxonomic validity ofS.feaeandS.formosensisis discussed in light of new specimen measurements. New ecological information on the swarming periods of 11 species is presented on the basis of year-long sampling of aerial insects. Finally, the importance of our results within Southeast Asia and the need for future sampling efforts in the region is discussed.

Correct mosquito species identification is essential for mosquito and disease control programs. However, this is complicated by the difficulties in morphologically identifying some mosquito species. In this study, variation of a partial sequence of the cytochromecoxidase unit I (COI) gene was used for the molecular identification of British mosquito species and to facilitate the discovery of cryptic diversity, and monitoring invasive species. Three DNA extraction methods were compared to obtain DNA barcodes from adult specimens. In total, we analyzed 42 species belonging to the generaAedesMeigen, 1818 (21 species),AnophelesMeigen, 1818 (7 species),CoquillettidiaTheobald, 1904 (1 species),CulexLinnaeus, 1758 (6 species),CulisetaFelt, 1904 (7 species), andOrthopodomyiaTheobald, 1904 (1 species). Intraspecific genetic divergence ranged from 0% to 5.4%, while higher interspecific divergences were identified betweenAedesgeminusPeus, 1971/Culisetalitorea(Shute, 1928) (24.6%) andAe.geminus/An.plumbeusStephens, 1828 (22.5%). Taxonomic discrepancy was shown betweenAn.daciaeLinton, Nicolescu & Harbach, 2004 andAn.messeaeFalleroni, 1828 indicating the poor resolution of theCOIDNA barcoding region in separating these taxa. Other species such asAe.cantans(Meigen, 1818)/Ae.annulipes(Meigen, 1830) showed similar discrepancies indicating some limitation of this genetic marker to identify certain mosquito species. The combination of morphology and DNA barcoding is an effective approach for the identification of British mosquitoes, for invasive mosquitoes posing a threat to the UK, and for the detection of hidden diversity within species groups.
Widespread use of Lactobacillus OppA, a surface located protein, as an adhesin that recognises epithelial cell surface glycosaminoglycans
Authors: Martín C. , Escobedo S. , Suárez J.E. , Quirós L.M.
Published: March 2019

Specific adherence is the first requisite that a microorganism has to fulfil to become established onto a mucosal surface. It was previously shown that the OppA surface protein of Lactobacillus salivarius Lv72 bound HeLa cell cultures through interaction with glycosaminoglycans (GAGs). To determine whether this is a peculiarity of that strain or whether it can be extended to other lactobacilli, 12 strains, belonging to six species, were confronted with HeLa-cell cultures in the presence of soluble GAGs. Interference was observed to six of them, heparan sulphate and chondroitin sulphate C being more interfering than chondroitin sulphate A or chondroitin sulphate B. Furthermore, inhibition of the biosynthesis of GAGs or their elimination from the cell surface with specific enzymes also resulted in reduced adherence. Analysis of the surface proteome of Lactobacillus crispatus Lv25 and of Lactobacillus reuteri RC14 revealed single proteins that immunoreacted with antibodies raised against OppA, the main adhesin of L. salivarius Lv72. Upon MALDI-TOF-TOF analysis, they were identified as OppA-like proteins, thus indicating that these proteins participate as adhesins in attachment of diverse lactobacilli to the surface of human epithelial cells.
Intersectional critique and social media activism in "Sleepy Hollow" fandom
Authors: Arcy Jacquelyn , Johnson Zhana
Published: March 2019

We examine fans' social media engagement with the supernatural detective series Sleepy Hollow (2013–17) and argue that fan discourses about the African American police detective Abbie Mills address the representational and institutional treatment of women of color. Sleepy Hollow fans use social media to counter and reshape industry narratives that often cast Black women as archetypes. We explore how fans recreate meaning by writing fan fiction, how fans collectively critique stereotypes on social media, and how fan boycotts challenge media institutions. By charting the evolution of fan responses to Abbie Mills's narrative arc over three seasons, we explore the potential for fan actions to disrupt the television industry. While fan activism is unlikely to alter the industry objectives of a capitalist media system or reconfigure power dynamics between producers and consumers, organized actions can resist institutional efforts to channel fan activity into show promotion.
PROBABILITY RANDOM INDEX BASED CLUSTERING FOR SEGMENTATION OF PET-CT IMAGES
Authors: Guruprasad S. , Kurian M. Z. , Suma H. N.
Published: March 2019

Medical image segmentation is a vital process in medical diagnosis and evaluation of tumor response to therapy. Current segmentation methods works only on single modality image like positron emission tomography has low resolution and gives only functional information; Computed Tomography has low contrast and provides structural information. This paper focus on segmentation of multimodality PET-CT image. In recent days PET-CT is advanced multimodal imaging equipment, which gives both functional and anatomical information in a single image. Probability random index is a new methodology adopted to segment the portion of an image, which is most essential for determining the actual intricacies involved in the portion of a body. The clustering is another methodology used to group similar pixel locations into a single group based on unpredictable random values of an image. The probability based clustering has been incorporated to overcome the drawbacks of existing methods of segmentation like over segmentation and under segmentation. The over segmentation has been eliminated by incorporating random values generated from the features of dataset of images. Similarly under segmentation has been eliminated by removing barriers of lack of collecting similarly values from clustering. Thus, the proposed method eliminates both over segmentation and under segmentation drawbacks of the existing methods. The proposed probability random index based clustering has yielded good results in comparision with other contemporary methods, which shall be observed from the section, results and analysis. The proposed probability random indexed clustering has yielded a good result of 88.41% on benchmark dataset.

Published: March 2019

Pacientes à espera de um transplante renal enfrentam situações complexas que ultrapassam o processo biológico. Assim, objetivou-se conhecer sentimentos e expectativas de pacientes com Doença Renal Crônica em relação ao transplante renal. Trata-se de um estudo de abordagem qualitativa, com pacientes em diálise, em um Hospital Universitário. Foram utilizados um questionário para caracterização socioeconômica e um roteiro de entrevista semiestruturada. A amostra atendeu ao critério de saturação. Os dados foram analisados a partir da análise de conteúdo na modalidade temática. Da análise, emergiram duas unidades temáticas: sentimentos provocados pela espera, destacando-se impotência, ansiedade, angústia, instabilidade e desmotivação; e expectativas de mudança após o transplante, com melhor qualidade de vida, fim da dependência da hemodiálise e retorno ao trabalho. A possibilidade de reintegração social, retorno ao trabalho ou a chance de não estar à mercê dos sintomas associados à diálise tornam o transplante principal fonte de esperança do portador de DRC.

Objetivo: avaliar se características da família e da criança interferem na capacidade familiar para cuidar de crianças expostas ao HIV, nas dimensões de quimioprofilaxia, acompanhamento clínico e imunizações. Método: Estudo transversal foi realizado com 86 participantes, entrevistados em serviço especializado para HIV, no interior do Rio Grande do Sul, utilizando a Escala de avaliação da capacidade para cuidar de crianças expostas ao HIV. Resultados: A alta capacidade (91,9%) para a quimioprofilaxia com AZT foi significativa quando: 3 a 5 pessoas vivem com a mesma renda (p = 0,10), a criança não tinha irmãos expostos ao HIV (p = 0,033) e não faltaram as consultas (p = 0,10). Para quimioprofilaxia com antibiótico (87,2%): a criança realizou nove ou mais consultas/ano (p = 0,010) e não apresentou problema de saúde (p = 0,008). Para o acompanhamento clínico e imunizações (98,8%): o familiar possuía carteira assinada (p = 0,044) e considerou fácil manter acompanhamento (p = 0,000); a criança não apresentou problema de saúde (p = 0,000) e não fazia outro acompanhamento (p = 0,001). Conclusão: Características da família (≤ 5 pessoas/renda e não ter outras crianças com HIV), do familiar-cuidador (carteira assinada e percepção de facilidade de manter o tratamento) e da criança (não ter outro problema/demanda de acompanhamento de saúde e assiduidade nas consultas) interferem positivamente na capacidade familiar de cuidar.

Allopatric separation represents an overlooked cryptic species in the Anania hortulata species complex (Lepidoptera: Crambidae: Pyraustinae): congruence between genetic and morphological evidence
Authors: Yang Zhaofu , Landry Jean-François
Published: March 2019

Anania hortulata (Linnaeus, 1758) (Lepidoptera: Crambidae: Pyraustinae) is a strikingly coloured, common, and widespread species that has long been recognised as a single species widely distributed in Asia, Europe, and North America. Using a combination of molecular and morphometric data, this study resolved that A. hortulata is actually a species complex of two superficially indistinguishable species. Phylogenetic and network analyses based on the mitochondrial COI gene discriminated lineages from all major geographical regions of China as distinct, A. sinensis Yang and Landry new species, whereas A. hortulata occurs in Central Asia, Europe, and North America. Nuclear gene (CAD) and morphological differences in the genital characters provided further evidence for the separation of A. hortulata and A. sinensis.

The presence of antibiotic residues in beef is considered a serious threat to public health. This study aimed to detect antibiotic residues in raw beef and the impact of low and high temperature treatments on residues persistence. A total of 250 sampleswere collected from retail markets in Erbil city (Iraq) and analyzed microbiologically in plates pre-inoculated with Bacillus subtilis. The overall occurrence of antibiotics residues was (10.8%).The highest rate was detected in January (16.7%). Cooking for thirty minutes completely deactivate antibiotic residues against the challenged bacterium. In conclusion, the presence of antibiotic residues in beef samples in Erbil city was high and their persistence is markedly reduced by cooking.
A pinnotheroid pea crab (Decapoda, Brachyura, Pinnotheridae), from the early Pliocene of Cassine (Alessandria, Piemonte, NW Italy)
Authors: Pasini Giovanni , Garassino Alessandro
Published: March 2019

A pinnotheroid pea crab (Pinnotheridae De Haan, 1833), is here reported from the Zanclean (early Pliocene) clays of a quarry located S-SW of Cassine (Alessandria, Piemonte, NW Italy). Though the studied specimen cannot be assigned to any genus within the Pinnotherinae (Pinnotheridae De Haan, 1833), it is the first record from the Pliocene of Italy and paleo-Adriatic Gulf, increasing the knowledge of the presence and fossil distribution of this family in the Mediterranean area.
User manual, source code, and test set for MSBASv3 (Multidimensional Small Baseline Subset version 3) for one- and two-dimensional deformation analysis
Authors: Samsonov S V
Published: March 2019

Time series of ground deformation are used to describe motion produced by various natural and anthropocentric processes, such as earthquakes, volcanic eruptions, landslides, subsidence due to resource exploitation and uplift due to fluid injection. The
Multidimensional Small Baseline Subset version 3 (MSBASv3) software simultaneously processes multiple ascending and descending Differential Interferometric Synthetic Aperture Radar (DInSAR) data sets and produces either one-dimensional, line-of-sight, or two-dimensional, horizontal east-west and
vertical, deformation time series with combined temporal resolution. The set of linear equations solved by MSBASv3 is usually rank deficient and is solved in the least-square sense by applying the Singular Value Decomposition (SVD) and the zero, first, or second order Tikhonov regularization. The
MSBASv3 source code is written in C++ and is parallelized using OpenMP. It is linked to the Linear Algebra PACKage (LAPACK) library that provides SVD support and to the Geospatial Data Abstraction Library (GDAL) that provides GeoTiff support. To demonstrate the capabilities of the MSBASv3 a test set
of ascending and descending RADASAT-2 data over the Barnes Ice Cap (Baffin Island, Nunavut, Canada) during December 2014 - May 2015 is included and is used throughout this user manual to illustrate the processing sequence.

Authors: Fung Miranda M. Y. , Kao Henry S. R. , Lam Stewart P. W. , Kao Tin Tin
Published: March 2019

Purpose:

To investigate the intervention effects of using traditional Chinese Guqin music and Chinese Calligraphy handwriting (CCH) for patients with Primary Insomnia.

Methods:

A total of ninety patients were assigned to control group, Guqin group, and calligraphy group for 8 weeks. For 5 days a week, patients’ heart rate variability (HRV) and frontal midline (FZ) electroencephalographic signals were recorded in a clinic during interventional period while either listening to Guqin music or writing calligraphy. Patients in the control group remained in rest condition.

Results:

For the Guqin group, the higher low-frequency-range HRV of coherence was found with marginal significance (P = 0.055), and heart rate was significantly reduced (P < 0.05) during the 4th week in listening to Guqin music compared to the prerest period. For listening to Guqin music or calligraphy intervention, FZ δ, FZ θ, and FZ α waves in the 8th week compared to the 0th week (Pre Intervention) showed a significantly enhanced effect (P < 0.05). Between the three groups, for heart rate and FZ δ and FZ θ waves, calligraphy group showed significantly increased heart rate than the Guqin group (P < 0.001)and the control group (P = 0.004); increased FZ δ wave than the Guqin group (P < 0.001) and the control group (P < 0.001); and increased FZ θ wave than the Guqin group (P = 0.024) and the control group (P = 0.008) respectively.

Conclusion:

Positive intervention effects on HRV coherence of Guqin music; FZ δ, FZ θ, and FZ α waves of Guqin music and calligraphy proved that Guqin music together with calligraphy training helping to promote physical and mental health, thereby it contributes to the clinical application of TCM Psychology for patients with insomnia syndrome.

The compilation of Compendium of Materia Medica by Li Shizhen is the product of both his great dream of writing and years of diligent work and it was also all round related to the historical times when he lived. At that time, the appreciation from the Emperor, competitive publication of medical works by the state kings and the rapid developments in medicine in the Ming dynasty all contributed to the establishment of a solid foundation for the success of Compendium of Materia Medica. This paper explored the contributing factors of the great work from a perspective of the historical environment.
Beijing genotype dominance among circulating mycobacterium tuberculosis in patients with pulmonary tuberculosis in belarus
Authors: Slizen Veronica V , Surkova Larisa K , Titov Lenoid P
Published: March 2019

Aim and objectives:

The surveillance of genetic diversity and genotypes of Mycobacterium tuberculosis (MTB), such as Beijing, Beijing B0/W148 genotypes, T (T1), LAM (LAM 9), U, X, Manu 2, H4, is important for Belarus to evaluate mycobacterial population shift under vaccination and demographic changes and the use of new anti-TB drugs.

Methods:

There were 241 isolates of MTB processed in the study, of which 108 MTB were isolated in Minsk and Minsk region, 83, 21, 20 - in Mogilev, Gomel, Grodno regions, 9 – in Brest region, 1 culture - in Vitebsk; 7 were isolated from males with no fixed abode. The gender distribution of studied MTB was as follows: 172 cultures (71.4 ± 3.4%) from males and 69 isolates (28.6 ± 5.44%) from females. An express multiplex real time PCR method with dual hydrolysis probes was used to differentiate Beijing and non-Beijing genotypes of M.tuberculosis. Standard PCR with primers INS1, Rv2665R, W139F2T was applied to identify lineage B0/W148 of Beijing genotype. NGS (both Illumina MiSeq and Oxford Nanopore MiniION) was used to characterize genome of M.tuberculosis genotype Beijing lineage B0/W148.

Results:

The study provides evidences of Beijing genotype dominance among circulating M.tuberculosis in patients with pulmonary tuberculosis in Belarus. The proportion of Beijing genotype in patients with primary diagnosed TB was 61,7% (29/47). The frequency of Beijing genotype isolation in Minsk, Mogilev, Gomel and Grodno regions was 51.85 ± 9.62, 66.27 ± 10.38, 85.71 ± 15.93, 55 ± 23.28% respectively. The lineage B0/W148 accounted for 22.82 ± 5.41% of all isolates and 37.93 ± 8.29% of the Beijing genotype isolates. The genetic clone B0/W148 was revealed in Minsk, Mogilev, Gomel, and Grodno regions, where its proportion among isolates of the Beijing genotype accounted for 44.64 ± 13.22, 23.64 ± 13.48, 33.33 ± 24.33, 72,73 ± 33.59%, respectively. The genetic variant B0/W148 was characterized by a high level of transmission (53.22%) mainly among the male population (p <0.05), unemployed, disabled people of the 2nd group, pensioners, by dominant spread in Minsk and Grodno regions (p < 0.05), a higher frequency of drug resistance (all strains are either pre-XDR or XDR) and to a wider range of anti-TB drugs. Sequenced genome of of M.tuberculosis strain 5005 belonging to genotype Beijing lineage B0/W148 (biosample in GenBank - SAMN14150054), sized 4418311 nt, was downloaded to GenBank - accession number CP049108.1.

Conclusion:

Epidemiology of tuberculosis in Belarus is characterized by spread of M. tuberculosis belonging to genotype Beijing (61.7 ± 7.1% of newly diagnosed patients) that has high degree of association with pre-XDR tuberculosis (p <0.05) and ineffective treatment (primary and secondary (p <0.05)).
Stability of Restrictions of the Cotangent Bundle of Irreducible Hermitian Symmetric Spaces of Compact Type
Authors: Biswas Indranil , Chaput Pierre-Emmanuel , Mourougane Christophe
Published: March 2019

It is known that the cotangent bundle

\Omega_Y

of an irreducible Hermitian symmetric space

Y

of compact type is stable. We show that if

X \subset Y

is a subvariety whose structure sheaf has a short split resolution and such that the restriction map Pic

(Y) \to

Pic

(X)

is surjective, then, apart from a few exceptions, the restriction

\Omega_{Y|X}

is a stable bundle. We then address some cases where the Picard group increases by restriction.
A $p$-adic Analytic Approach to the Absolute Grothendieck Conjecture
Authors: Murotani Takahiro
Published: March 2019

Let

K

be a field,

G_K

the absolute Galois group of

K

,

X

a hyperbolic curve over

K

and

\pi_1(X)

the \'{e}tale fundamental group of

X

. The absolute Grothendieck conjecture in anabelian geometry asks the following question: Is it possible to recover

X

group-theoretically, solely from

\pi_1(X)

(not

\pi_1(X)\twoheadrightarrow G_K

)? When

K

is a

p

-adic field (i.e., a finite extension of

\mathbb{Q}_p

), this conjecture (called the

p

-adic absolute Grothendieck conjecture) is unsolved. To approach this problem, we introduce a certain

p

-adic analytic invariant defined by Serre (which we call

i

-invariant). Then the absolute

p

-adic Grothendieck conjecture can be reduced to the following problems: (A) determining whether a proper hyperbolic curve admits a rational point from the data of the

i

-invariants of the sets of rational points of the curve and its coverings; (B) recovering the

i

-invariant of the set of rational points of a proper hyperbolic curve group-theoretically. The main results of the present paper give a complete affirmative answer to (A) and a partial affirmative answer to (B).
Blind downlink channel estimation for TDD‐based multiuser massive MIMO in the presence of nonlinear HPA
Authors: Pasangi Parisa , Atashbar Mahmoud , Feghhi Mahmood Mohassel
Published: March 2019

In time division duplex (TDD)‐based multiuser massive multiple input multiple output (MIMO) systems, the uplink channel is estimated and the results are used in downlink for signal detection. Owing to noisy uplink channel estimation, the downlink channel should also be estimated for accurate signal detection. Therefore, recently, a blind method was developed, which assumes the use of a linear high‐power amplifier (HPA) in the base station (BS). In this study, we extend this method to a scenario with a nonlinear HPA in the BS, where the Bussgang decomposition is used for HPA modeling. In the proposed method, the average power of the received signal for each user is a function of channel gain, large‐scale fading, and nonlinear distortion variance. Therefore, the channel gain is estimated, which is required for signal detection. The performance of the proposed method is analyzed theoretically. The simulation results show superior performance of the proposed method compared to that of the other methods in the literature.
Cellule XIII de Jean Rogissart : fusion des éléments du français hors norme
Authors: Retinskaya Tatiana
Published: March 2019

Les unités hors norme constituent une partie importante du roman régional. Ce sont des régionalismes qui dominent les éléments du vocabulaire en question. Cependant le roman de Jean Rogissart Cellule XIII se distingue considérablement des textes des écrivains régionalistes. Dans le cadre de ce travail, nous proposons l’analyse de deux segments du substrat non codifié ci-dessous : 1) des formes répandues dans une aire ; 2) des unités appartenant à l’argot traditionnel. Il est à noter que le titre de notre article contenant le mot « fusion » montre l’importance de deux sous-systèmes de la langue dans la narration : l’insertion des lexèmes localement limités ainsi que des argotismes dans le tissu du texte est nécessaire pour l’identification des locuteurs et la caractérisation plus précise des événements. L’auteur ardennais qui a consacré son dernier roman à la guerre a réussi non seulement à décrire la souffrance physique et morale subie par le peuple, mais aussi à graver les traits les plus typiques du langage de ses compatriotes et de cette façon à sauvegarder le patrimoine linguistique. L’étude des termes régionaux et argotiques utilisés par le maître du roman ardennais et des outils de leur explication textuelle permet de décrypter les particularités du parler localement limité et de présenter le statut social de l’utilisateur du régiolecte et sa vision du monde.

 

Nonconventional lexical units have an important place in the regional novel. Regionalisms dominate among the elements of the marked vocabulary. However, the novel Cellule XIII by Jean Rogissart is considerably different from the works of writers-regionalists. In this study, we propose an analysis of the two following segments of an uncodified substrate: 1) local lexemes; 2) lexemes of a traditional argot. It is worth noting that the title of the article, which contains the word “fusion”, shows the importance of two language subsystems in the narrative: the insertion of territorially restricted units and argotisms into the fabric of an artistic text is necessary to identify the speaker and a more accurate description of events.

The Ardennes author who devoted his novel to the theme of war, the main theme of the 10th International Conference on Argotology, managed not only to describe the physical and moral sufferings of the people, but also to engrave the characteristic features of their compatriots, and thus preserve the linguistic heritage. The study of the regional and argotic vocabulary used by the Ardennes novelist, and the techniques of its textual explication, makes it possible to decode the features of locally limited units and characterize the social status of a regional speaker and their worldview.
« Bonaparte ne chevauchait en personne entre les lignes de tir et les troupes et attisait le courage dans les cœurs ». L'influence du français sur le vocabulaire militaire dans Ljubljanske novice de Valentin Vodnik
Authors: Smolej Mojca
Published: March 2019

Dans la présente contribution, nous étudierons plus spécialement l’influence de la langue française sur l’usage du vocabulaire militaire dans Ljubljanske novice (Les Nouvelles de Ljubljana, 1797-1800) de Valentin Vodnik. L’analyse du vocabulaire militaire montre que Vodnik a construit les fondements de la terminologie militaire slovène, mais il faut souligner que nous sommes en présence d’articles de journaux ayant une autre fonction et poursuivant d’autres objectifs que les textes techniques strictement militaires. Dans les Ljubljanske novice, Vodnik décrit la situation militaire en Europe à la fin du XVIIIe siècle, notamment les guerres napoléoniennes, à l’aide de descriptions et de nombreux exemples. Pour élaborer la terminologie militaire slovène, Vodnik a souvent opté pour un emprunt aux langues étrangères, en priorité au français, ce qui fera plus spécialement l’objet de notre attention. Dans le vocabulaire repris du français, nous pouvons remarquer aussi bien des emprunts que des mots étrangers adaptés et cités. À la fin de cette présentation des expressions militaires de Vodnik, nous les comparerons brièvement avec la langue militaire de Andrej Komel. Comme le dictionnaire de Komel est considéré comme le fondement de la terminologie militaire slovène, nous allons regarder combien d’expressions militaires reprises du français par l’intermédiaire de l’allemand utilisées par Vodnik ont subsisté et ont été incluses dans le dictionnaire de Andrej Komel.
