The article evaluates the aims and methods of creation of the so-called “Arabic-Ethiopic Glossary”, a 14th century word list compiled by order of the Yemenite sultan of the Rasulid dynasty al-Malik al-Afḍal al-ʿAbbās b. ʿAlī. It claims that the Glossary was created with a purely scientific aim of recording a little-known language, that its compilers were likely unaware of the linguistic diversity of the recorded material (hence the name “Ethiopic” in the title), and that the informants were in all probability Ethiopian slaves who, as is well known, were present in South Arabia since Antiquity.

Для класса графов X, через Xn обозначается количество графов с множеством вершин {1, . . . , n} из класса X. Класс X называется факториальным, если X – наследственный (т.е. замкнут относительно изоморфизма и операции удаления вершины) и nc1n ≤ X ≤ nc2n для некоторых положительных констант c1 и c2. Граф G называется квазиреберным, если окрестность каждой его вершины может быть разбита на две клики. В настоящей работе описываются почти все факториальные подклассы класса квазиреберных графов, определяемые одним запрещенным порожденным подграфом. Используя этот результат, в работе доказывается, что класс Free(K1,3,W4) факториальный, что обобщает один из результатов работы [8].

Interval translation maps (ITMs) are a non-invertible generalization of interval exchange transformations (IETs). The dynamics of finite type ITMs is similar to IETs, while infinite type ITMs are known to exhibit new interesting effects. In this paper, we prove the finiteness conjecture for the ITMs of three intervals. Namely, the subset of ITMs of finite type contains an open, dense, and full Lebesgue measure subset of the space of ITMs of three intervals. For this, we show that any ITM of three intervals can be reduced either to a rotation or to a double rotation.

A lower bound is derived for the value of an option by applying threshold decision rules based on the ratio of the underlying asset values. When the asset volatility ratio is equal to the correlation coefficient, the lower bound is equal to the maximum value obtained by optimizing a function of two variables represented as the sum of a rapidly converging series.

Preeclampsia is a pregnancy complication which causes significant maternal and fetal morbidity and mortality worldwide. Although intensive research has been performed in the last 40 years, the pathology of preeclampsia is still poorly understood. The present work is a comparative study of the myometrium of women with normal pregnancy, and those with late- and early-onset preeclampsia (n = 10 for each group). We observed significant changes in the levels of antioxidant enzymes, markers of mitochondrial biogenesis and autophagyproteins in preeclamptic myometrium. Levels of superoxide dismutase 1 and catalase were lower in both preeclamptic groups than the control group. In late-onset preeclampsia, expression levels of essential mitochondria-related proteins VDAC1, TFAM, hexokinase 1, PGC-1α and PGC-1β, and autophagy marker LC3A, were significantly elevated. In the myometrium of the early-onset preeclampsia group OPA1 and Bcl-2 were up-regulated compared to those of the control (p < 0.05). These findings suggest that crucial molecular changes in the maternal myometrium occur with the development of preeclampsia.

Despite being the object of a thriving field of clinical research, the investigation of intrinsic brain network alterations in psychiatric illnesses is still in its early days. Because the pathological alterations are predominantly probed using functional magnetic resonance imaging (fMRI), many questions about the electrophysiological bases of resting-state alterations in psychiatric disorders, particularly among mood disorder patients, remain unanswered. Alongside important research using electroencephalography (EEG), the specific recent contributions and future promise of magnetoencephalography (MEG) in this field are not fully recognized and valued. Here, we provide a critical review of recent findings from MEG resting-state connectivity within major depressive disorder (MDD) and bipolar disorder (BD). The clinical MEG resting-state results are compared with those previously reported with fMRI and EEG. Taken together, MEG appears to be a promising but still critically underexploited technique to unravel the neurophysiological mechanisms that mediate abnormal (both hyper- and hypo-) connectivity patterns involved in MDD and BD. In particular, a major strength of MEG is its ability to provide source-space estimations of neuromagnetic long-range rhythmic synchronization at various frequencies (i.e., oscillatory coupling). The reviewed literature highlights the relevance of probing local and interregional rhythmic synchronization to explore the pathophysiological underpinnings of each disorder. However, before we can fully take advantage of MEG connectivity analyses in psychiatry, several limitations inherent to MEG connectivity analyses need to be understood and taken into account. Thus, we also discuss current methodological challenges and outline paths for future research. MEG resting-state studies provide an important window onto perturbed spontaneous oscillatory brain networks and hence supply an important complement to fMRI-based resting-state measurements in psychiatric populations.

The article compares the ideas of four thinkers of the nineteenth century - Joseph de Maistre, Thomas Carlyle, Karl Marx and Jules Michelet - who, in various aspects, outlined the problems of the non-religious sacred, that is, of the "absolutely different" in personal and social experience.

Современная международная валютная система из-за ее недостатков требует кардинальных изменений. Поэтому, экономистами всего мира предлагаются варианты создания альтернативных международных валют, которые бы позволили международной валютной системе работать эффективнее. Важно, создавая новую международную валюту, анализировать и учитывать опыт всех предшествующих международных валют. Поэтому, в начале статьи, последовательно анализируются недостатки каждого варианта фактически существующей и существовавшей международной валюты.  Опираясь на проведенный анализ, обосновывается необходимость введения новой международной валютной единицы, и  задаются требования, которым она должна удовлетворять. Далее в работе предлагается альтернативный, теоретически возможный вариант международной валюты - валюта, привязанная к корзине товаров. На абстрактном примере определяется ее содержание и механизм обращения.

It has always been peculiar to evolutionists to compare social and biological evolution, the latter as visualized by Charles Darwin.1 But it also seems possible and correct to draw an analogy with another great discovery in the field of evolutionary biology, with the homologous series of Nikolay Vavilov (1921; 1927; 1967). However, there is no complete identity between cultural parallelism and biological homologous series. Vavilov studied the morphological homology, whereas our focus within the realm of social evolution is the functional one. No doubt, the morphological homomorphism also happens in the process of social evolution (e.g. in the Hawaii Islands where a type of the sociocultural organization surprisingly similar with the ones of other highly developed parts of Polynesia had independently formed by the end of the 18th century [Sahlins 1972/1958; Goldman 1970; Earle 1978]). But this topic is beyond the present paper’s problématique.

The  concept  of  Nature,  which  has  been  central  to  the  common comprehension  of  life  throughout  Russia’s  ancient  history,  has  never  been epistemologically neutral. It was clearly embedded in paganism and  its  underlying  values  and  canons.  What  is  significant  is  that  paganism’s essential  understanding  of  Nature  as  divine  has  been  radically  retailored  to achieve very divergent ends. The interpretation of Nature began to reflect the beliefs  not  of  the culture  as a whole but  of the few who  deemed  themselves responsible to institute a more advanced culture in place of the existing one. In particular, the process of man’s abstraction from Nature has been taking place through concrete historical events.
