Published: March 2018

Вторая версия каталога средних магнитных фазовых кривых (МФК) содержит сведения о 308 звездах различных типов. За время, прошедшее после создания первого каталога (Бычков и др., 2005), ситуация принципиально изменилась в первую очередь из-за того, что существенно повысилась точность измерения магнитных полей (МП). В настоящее время у многих типов звезд обнаружены глобальные магнитные поля и частично изучено их поведение. Наиболее детально изучено магнитное поведение Ар - Вр звезд. В каталоге содержатся сведения о 190 таких объектах. Основные цели создания каталога:

Обзор и обобщение накопленного наблюдательного материала о магнитном поведении разных типов звезд.
Проведение статистического анализа переменности магнитных полей звезд на основании собранных и однородно обработанных измерений.
Определение ориентации осей вращения звезд.
Для проверки различного рода теоретических моделей сведения представлены в наиболее удобной форме.
Каталог будет полезен для разработки наблюдательных программ.
Настоящий каталог открывает дополнительные возможности для исследования звезд, имеющих экзопланеты.
Квантово-механический подход к описанию поляризационного просветления фотосферы белого карлика с сильным магнитным полем для инфракрасного излучения
Authors: Корягин С.А. 
Published: March 2018

В условиях фотосферы одиночного белого карлика с температурой порядка 1 эВ и магнитным полем свыше 10 МГс существенно уменьшается коэффициент столкновительного поглощения излучения для необыкновенной волны (поляризованнойпоперек внешнего магнитного поля) в диапазоне ниже электронной циклотронной частоты. При классическом описании движения частиц, поляризационное просветление холодной плазмы в сильном магнитном поле обусловлено наличием полностью связанных электронных траекторий с положительной энергией вблизи протона. В работе показано, что в квантовом пределе сохраняется поляризационное просветление фотосферы магнитного белого карлика для необыкновенной волны. Таким образом, высокая линейная поляризация наблюдаемого инфракрасного излучения одиночных белых карликов с наиболее сильным квантующим магнитным полем может быть обусловлена тем, что, в результате поляризационного просветления, необыкновенные волны выходят из более глубоких и горячих слоев фотосферы, чем волны с ортогональной поляризацией.

Работы по сравнению и комбинации каталогов координат радиоисточников в Пулковской обсерватории
Authors: Лопез Ю.Р. , Малкин З.М. 
Published: March 2018

Описан опыт работ по сравнению и комбинации каталогов координат радиоисточников в Пулковской обсерватории (ГАО РАН) в 2006-2017 гг. Принятая процедура построения сводного каталога включает два этапа. Сначала разности между исходными каталогами и улучшаемой небесной системой отсчета ICRF (ICRF2) представляются рядом сферических функций по методу Броше. Затем каждый каталог исправляется за найденные разности (системы исходных каталогов), и исправленные каталоги усредняются. После этого усредняются вычисленные на первом этапе системы исходных каталогов, и полученная средняя система рассматривается как систематические поправки к исходной системе каталога ICRF. Сложение средней системы с каталогом, полученным на первом этапе, дает в результате окончательный сводный каталог. Первый пулковский сводный каталог был составлен в 2006 г. и позволил существенно улучшить точность определения всемирного времени и координат небесного полюса. Второй каталог был составлен в 2013 г. и позволил предварительно оценить систематические ошибки каталога ICRF2. Третий каталог 2016 г., описанный в настоящей работе, позволил уточнить эти ошибки.

Микроволновое излучение вспышечной петли при наличии турбулентности вистлеров
Authors: Мельников В.Ф. , Филатов Л.В. 
Published: March 2018

Рассмотрено влияние вистлеров на распределение и гиросинхротронное излучение быстрых электронов, инжектированных в вершину корональной магнитной ловушки. Для неоднородной петлеобразной ловушки решается кинетическое уравнение в приближении Фоккера - Планка, учитывающее рассеяние быстрых электронов на частицах фоновой плазмы и на вистлерах, заполняющих ловушку. Рассчитывается микроволновое излучение и проводится сравнение рассеяния нетепловых электронов на вистлерах и на частицах плазмы. Проводится сравнительный анализ зависимости параметров излучения от типа инжекции быстрых электронов в петлю (изотропно и продольно). Показано, что при плотности энергии вистлеров выше определенной характеристики излучения петли значительно изменяются.

Background: Despite common pathology, Alzheimer’s disease (AD) can have multiple clinical presentations which pathological studies suggest result from differences in the regional distribution of tau pathology. Positron emission tomography (PET) ligands are now available that can detect tau proteins in vivo and hence can be used to investigate the biological mechanisms underlying atypical AD. Objective: To assess regional patterns of tau uptake on PET imaging in two atypical AD variants, posterior cortical atrophy (PCA) and logopenic progressive aphasia (lvPPA). Methods: Eighteen PCA and 19 lvPPA subjects that showed amyloid-β deposition on PET underwent tau-PET imaging with [18F]AV-1451. Group comparisons of tau uptake in PCA and lvPPA were performed using voxel-level and regional-level analyses. We also assessed the degree of lobar tau asymmetry and correlated regional tau uptake to age and performance on clinical evaluations. Results: Both syndromes showed diffuse tau uptake throughout all cortical regions, although PCA showed greater uptake in occipital regions compared to lvPPA, and lvPPA showed greater uptake in left frontal and temporal regions compared to PCA. While lvPPA showed predominant left-asymmetric tau deposition, PCA was more bilateral. Younger subjects showed greater tau uptake bilaterally in frontal and parietal lobes than older subjects, and sentence repetition, Boston naming test, simultanagnosia, and visuoperceptual function showed specific regional tau correlates. Conclusion: Tau deposition is closely related to clinical presentation in atypical AD with age playing a role in determining the degree of cortical tau deposition.

Background: On target 18F-Flortaucipir (FTP) binding of Alzheimer’s disease tau aggregates and off-target binding of melanocytes have been demonstrated with autoradiography. Objective: We aimed to investigate the hypothesis that if binding in choroid plexus (CP) is due to melanocytes, the signal would be elevated in Black/African American (B/AA) compared to White (W) participants. In addition, we examined whether CP signal affects measurements in adjacent regions, and whether correcting for spill-in effects has an influence on associations between hippocampus (HC) FTP and amyloid or cognition. Methods: FTP race differences in 147 Harvard Aging Brain Study participants (23 B/AA, 124W) were examined in CP, HC, HC covaried for CP, amygdala, inferior temporal gyrus, entorhinal cortex, and fusiform regions. Associations between CP FTP and other regions-of-interest (ROIs) were probed to assess spill-in effects. A statistical regression approach to attenuate CP spill-in was tested by relating adjusted HC SUVR residuals and unadjusted HC SUVR to race, cognition and amyloid. All analyses were covaried for age, sex, education and amyloid deposition, and Bonferroni-corrected for multiple comparisons. Results: B/AA individuals had elevated CP and HC SUVR ( p < 0.007), whereas other ROI SUVR and HC SUVR covaried for CP SUVR did not show race differences ( p > 0.05). CP SUVR was associated with HC SUVR ( p < 10–14), but with no other ROI SUVR ( p > 0.05). When adjusting HC SUVR for CP SUVR, no race differences in residual HC SUVR were detected, and relationships with amyloid and memory became apparent. Conclusion: Melanocyte FTP binding may account partially for high CP signal. This off-target binding affects mainly HC FTP measurements, which should be interpreted with caution.

Background: Odor identification deficits occur in Alzheimer’s disease (AD), as measured by the 40-item University of Pennsylvania Smell Identification Test (UPSIT). Objective: To determine if UPSIT scores predict amyloid-β (Aβ) status, determined by 11C-Pittsburgh Compound B PET. We also compared UPSIT scores to Aβ status in predicting future memory decline. Methods: Subjects were recruited into a longitudinal clinical prediction study. We analyzed data from those who had UPSIT, cognitive testing, PIB PET, and at least 12 months’ clinical follow-up. Forty-six amnestic mild cognitive impairment patients and 25 cognitively normal controls were included. Amyloid-positivity was defined as composite PIB standardized uptake value ratio >1.5. Logistic regression and Receiver Operating Characteristic Curve analyses tested the predictive utility of impaired olfaction (defined as UPSIT score <35) and amyloid-positivity for memory decline. Results: High UPSIT scores predicted absence of amyloidosis on PET, with negative predictive value of 100%. Positive predictive value of low UPSIT scores on positive Aβ status was only 41%. Both low UPSIT score (OR = 4.301, 95% CI = 1.248, 14.821, p = 0.021) and positive PET scan (OR = 20.898, 95% CI = 2.222, 196.581, p = 0.008) predicted memory decline. Conclusion: Individuals with high UPSIT scores are less likely to have cerebral amyloidosis or experience memory decline. Therefore, UPSIT has potential as a screening tool to determine utility of Aβ PET in clinical practice or enrollment in clinical trials. Low UPSIT score is a non-specific marker of neurodegeneration that could indicate further workup in patients with memory complaints.

Published: March 2018

Background: During the twentieth century, frontotemporal dementia (FTD) was often misdiagnosed, confused with Alzheimer’s disease or psychiatric disorders, jeopardizing care and research. Objective: To analyze the FTD genes in the DNA samples of patients belonging to families clinically classified as probable Alzheimer’s disease (FAD) in the early 1990s and not carrying mutation in the three main genes linked to FAD (Presenilin 1, Presenilin 2, and Amyloid precursor protein). Methods: The genetic screening was performed on 63 probands diagnosed as FAD before the early 2000s. Results: Four patients out of the 63 studied (4/63, 6.3%) resulted as carrying four different GRN genetic variations: p.T272SfsX10, p.R110X, p.C149LfsX10, and p.W304C. The first two mutations (p.T272SfsX10, p.R110X) are the most frequent ones in Italy in FTD patients; the latter two (p.C149LfsX10 and p.W304C) are not described in the scientific literature. Conclusion: Our data suggest that it can be important to re-examine FAD patients diagnosed when the FTD spectrum was not well recognized and the causative FTD genes had not yet been identified. Moreover, we propose initially analyzing genes associated with the first form of suspected dementia and, if the results are negative, studying genes implicated in the other form of dementia.
Discovery of New Coronal Lines at 2.843 and 2.853 μm

Published: March 2018

Abstract
Two new emission features were observed during the 2017 August 21 total solar eclipse by a novel spectrometer, the Airborne Infrared Spectrometer (AIR-Spec), flown at 14.3 km altitude aboard the NCAR Gulfstream-V aircraft. We derive wavelengths in air of 2.8427 ± 0.00009 μm and 2.8529 ± 0.00008 μm. One of these lines belongs to the

transition in Ar-like Fe ix. This appears to be the first detection of this transition from any source. Minimization of residual wavelength differences using both measured wavelengths, together with National Institute of Standards and Technology (NIST) extreme ultraviolet wavelengths, does not clearly favor assignment to Fe ix. However, the shorter wavelength line appears more consistent with other observed features formed at similar temperatures to Fe ix. The transition occurs between two levels within the excited

configuration, 429,000 cm−1 above the ground level. The line is therefore absent in photo-ionized coronal-line astrophysical sources such as the Circinus Galaxy. Data from a Fourier transform interferometer (FTIR) deployed from Wyoming show that both lines are significantly attenuated by telluric H2O, even at dry sites. We have been unable to identify the longer wavelength transition.
Suivi du langage d’enfants bilingues issus de milieux sociaux défavorisés : enjeux cliniques, pédagogiques et sociaux
Authors: Le Normand Marie-Thérèse , Kern Sophie 
Published: March 2018

Loin d’être un phénomène isolé, les situations de bilinguisme ou de plurilinguisme représenteraient au moins la moitié de la population mondiale. Dans tous les pays d’Europe, le contact avec d’autres cultures et d’autres langues se généralise. Si des retards de langage peuvent apparaître, ce n’est pas le bilinguisme qui est responsable mais bien souvent la pauvreté et les mauvaises conditions familiales et sociales qui ralentissent le développement du langage. Cette étude porte sur une cohorte de 22 enfants bilingues et de 43 enfants monolingues âgés de 18 à 24 mois : 39 enfants sont issus de milieux favorisés et 26 de milieux défavorisés. Ces enfants ont été suivis dans le cadre de la recherche-action Parler bambin sur une période de six mois dans plusieurs crèches de la zone urbaine sensible de Grenoble. Les résultats montrent que le bilinguisme ne constitue pas un risque de retard de langage chez ces enfants mais il peut le devenir comme chez les enfants monolingues qui vivent dans des milieux sociaux défavorisés. L’enjeu clinique, pédagogique et social de ces données plaide en faveur d’actions de prévention précoce qui ont comme objectif de favoriser l’égalité des chances de tous les enfants du berceau à la crèche pour les préparer à l’école, puis à la réussite sociale et professionnelle.
