Throughout the Japanese colonial period, Korea's reading public paid close attention to Chinese revolutions against Japanese and Western empires. Korean nationalists viewed China's revolutionary struggles as important for liberating Korea from Japan, a stance that reveals a transnational basis of Korean nationalism in the colonial era. One such nationalist was Sin Ŏnjun (1904–38), Tong'a Ilbo’s Shanghai-based correspondent, who played a critical role in conveying the momentous events in contemporary China to colonized Koreans. Drawing on Sin's example, this article shows how Sino-Korean transnationalism constituted Korea's left-wing, progressive nationalism in the 1930s. Although Sin Ŏnjun was a nationalist rather than a communist, he highlighted the communist struggles in China in his dispatches. He saw communism as the only viable way of solving China's internal and external problems, although he, at the same time, disapproved of Chinese communists’ “terrorist methods.” This article argues that this position also reflected his stance in favor of a broad communist-nationalist alliance in the Korean independence movement. He saw Korea's liberation agenda as closely related to the revolutionary events in China, thus accomplishing a synthesis between Korean nationalistic and social aspirations and an East Asia–wide transnational paradigm of a universal emancipatory struggle.

We study criteria for the uniform convergence of trigonometric series with general monotone coefficients. We also obtain necessary and sufficient conditions for a given rate of convergence of partial Fourier sums of such series.

A megaslump at Batagaika, in northern Yakutia, exposes a remarkable stratigraphic sequence of permafrost deposits ~50–80 m thick. To determine their potential for answering key questions about Quaternary environmental and climatic change in northeast Siberia, we carried out a reconnaissance study of their cryostratigraphy and paleoecology, supported by four rangefinder 14C ages. The sequence includes two ice complexes separated by a unit of fine sand containing narrow syngenetic ice wedges and multiple paleosols. Overall, the sequence developed as permafrost grew syngenetically through an eolian sand sheet aggrading on a hillslope. Wood remains occur in two forest beds, each associated with a reddened weathering horizon. The lower bed contains high amounts of Larix pollen (>20%), plus small amounts of Picea and Pinus pumila, and is attributed to interglacial conditions. Pollen from the overlying sequence is dominated by herbaceous taxa (~70%–80%) attributed to an open tundra landscape during interstadial climatic conditions. Of three hypothetical age schemes considered, we tentatively attribute much of the Batagaika sequence to Marine Oxygen Isotope Stage (MIS) 3. The upper and lower forest beds may represent a mid–MIS 3 optimum and MIS 5, respectively, although we cannot discount alternative attributions to MIS 5 and 7.

Two female woolly mammoth neonates from permafrost in the Siberian Arctic are the most complete mammoth specimens known. Lyuba, found on the Yamal Peninsula, and Khroma, from northernmost Yakutia, died at ages of approximately one and two months, respectively. Both specimens were CT-scanned, yielding detailed information on the stage of development of their dentition and skeleton and insight into conditions associated with death. Both mammoths died after aspirating mud. Khroma's body was frozen soon after death, leaving her tissues in excellent condition, whereas Lyuba's body underwent postmortem changes that resulted in authigenic formation of nodules of the mineral vivianite associated with her cranium and within diaphyses of long bones. CT data provide the only comprehensive approach to mapping vivianite distribution. Three-dimensional modeling and measurement of segmented long bones permits comparison between these individuals and with previously recovered specimens. CT scans of long bones and foot bones show developmental features such as density gradients that reveal ossification centers. The braincase of Khroma was segmented to show the approximate morphology of the brain; its volume is slightly less (∼2,300 cm3) than that of neonate elephants (∼2,500 cm3). Lyuba's premaxillae are more gracile than those of Khroma, possibly a result of temporal and/or geographic variation but probably also reflective of their age difference. Segmentation of CT data and 3-D modeling software were used to produce models of teeth that were too complex for traditional molding and casting techniques.

The paper deals with the trends of fascist and fascist-like right-wing social and political thought in colonial Korea in the early 1930s. It shows that in the 1920s, Korea's right wing, its ability to reach out to the masses being severely limited, preferred mostly conciliatory tactics in its relationship with leftist radicals, often making efforts towards inventing ‘hybrid’ ideologies which would integrate the leftist social concerns into the mainstream religious or nationalist constructions (an example of such a hybrid were various Korean versions of Christian socialism). After the Great Depression, however, Korea's nascent bourgeoisie felt more threatened and became more interested in keeping abreast with right-wing extremist trends in the mother country (Japan) and elsewhere. Such representative ideologists of the Korean propertied class as Yun Ch'iho and Yi Kwangsu were praising Mussolini and employing strong Social Darwinist language in their exhortations to the Korean people to ‘regain their vitality and develop [a] spirit of collectivism, obedience and self-sacrifice’. However, until the very end of the 1930s many of Korea's right-wing ideologues remained pronouncedly religious (Yun as Christian, Yi as Buddhist). While highlighting the religious essentials of their worldviews they often abstained from imitating the most extremist traits of European fascist ideologies (for example, anti-Semitism). In many ways, Korea's fascism continued until the end of the 1930s to be an intellectual discourse rather than a mass movement, and retained a strong aura of belonging to more mainstream religious or nationalist traditions.

The anthropogenic accidents in the world (including the underground emergency nuclear explosion at the site “Kraton-3” (Yakutiya) and also the recent Fukushima accident) resulted in significant environmental pollution by radionuclides, mainly long-lived 90Sr and 137Cs. One of the ways to solve this problem is the creation of “permeable reactive barriers” (PRBs). High selectivity of clinoptilolite-containing tuffs (CLT) towards Sr2+ and Cs+ radionuclides, together with their availability and reasonable cost, make possible their use as PRBs. The scales of the ion-exchange processes taking place on PRBs indicate the necessity of mathematical modelling. In this connection, Sr2+ and Cs+ ion-exchange sorption on Khonguruu CLT (Yakutiya) from solutions of various mineralizations was studied under equilibrium and non-equilibrium conditions. The physicochemical and mathematical models of the dynamic ion-exchange process and also the computer program considering both structural features of CLT (two-stage particle diffusion kinetics) and possible periodic interruptions of the process were developed. The breakthrough time of CLT as a geochemical barrier was calculated by such mathematical modelling.

We study (p, q)-inequalities of Ulyanov type for moduli of smoothness of fractional order in the Lp and the Lp(ℝn) setting, p ≥ 1. In particular, we obtain estimates for the modulus of smoothness of a generalized Liouville derivative of a function via the modulus of smoothness of the function itself. We give examples showing the sharpness of these inequalities.

Part of a large male woolly mammoth (Mammuthus primigenius) was preserved in permafrost in northern Yakutia. It was radiocarbon dated to ca. 18,50014C yr BP (ca. 22,500 cal yr BP). Dung from the lower intestine was subjected to a multiproxy array of microscopic, chemical, and molecular techniques to reconstruct the diet, the season of death, and the paleoenvironment. Pollen and plant macro-remains showed that grasses and sedges were the main food, with considerable amounts of dwarf willow twigs and a variety of herbs and mosses. Analyses of 110-bp fragments of the plastid rbcL gene amplified from DNA and of organic compounds supplemented the microscopic identifications. Fruit-bodies of dung-inhabiting Ascomycete fungi which develop after at least one week of exposure to air were found inside the intestine. Therefore the mammoth had eaten dung. It was probably mammoth dung as no bile acids were detected among the fecal biomarkers analysed. The plant assemblage and the presence of the first spring vessels of terminal tree-rings of dwarf willows indicated that the animal died in early spring. The mammoth lived in extensive cold treeless grassland vegetation interspersed with wetter, more productive meadows. The study demonstrated the paleoecological potential of several biochemical analytical techniques.

This paper deals with ideal masculine types in the gender discourse of Korea's modernizing nationalists during the late 1890s and early 1900s. It begins by outlining the main gender stereotypes of Korea's traditional neo-Confucian society, and it argues that old Korea's manhood norms were bifurcated along class lines. On one hand, fighting prowess was accepted as a part of the masculinity pattern in the premodern society of the commoners. On the other hand, the higher classes' visions of manhood emphasized self-control and adherence to moral and ritual norms. The paper shows how both premodern standards of masculinity provided a background for indigenizing the mid-nineteenth century European middle-class ideal of “nationalized” masculinity—disciplined, self-controlled, sublimating the sexual impulses and channeling them toward the “nobler national goals,” and highly militarized—in early modern Korea.

Current explanation of the overabundance of dark matter subhalos in the Local Group (LG) indicates that there maybe a limit on mass of a halo, which can host a galaxy. This idea can be tested using voids in the distribution of galaxies: at some level small voids should not contain any (even dwarf) galaxies. We use observational samples complete to MB = −12 with distances less than 8 Mpc to construct the void function (VF): the distribution of sizes of voids empty of any galaxies. There are ~ 30 voids with sizes ranging from 1 to 5 Mpc. We then study the distribution of dark matter halos in very high resolution simulations of the LCDM model. The theoretical VF matches the observations remarkably well only if we use halos with circular velocities larger than 45 ± 10 km/s. This agrees with the Local Group predictions. There are smaller halos in the voids, but they should not produce any luminous matter. Small voids look quite similar to their giant cousins: the density has a minimum at the center of a void and it increases as we get closer to the border. Small nonluminous halos inside the void form a web of tiny filaments. Thus, both the Local Group data and the nearby voids indicate that isolated halos below 45 ± 10 km/s must not host galaxies and that small (few Mpc) voids are truly dark.

We owe Professor Tikhonov warmest thanks for this brief history of academic archaeology at St Petersburg. As well as applauding the department's many achievements, readers of our Debate section will no doubt take note of a bleak period in its eventful history, one marked by a tendency to ‘substitute socio-political subjects for specialist courses’ and ‘the growing disparagement of highly skilled researchers and teachers’. If suitably candid authors can be found, we look forward to receiving similarly instructive intellectual biographies of archaeology departments and institutes from around the world.

We present a brief summary of our current results on the stellar distribution and population gradients of the resolved stars in the surroundings of ∼50 nearby disk galaxies, observed with space- (Hubble & Spitzer) and ground-based telescopes (Subaru, VLT, BTA, Palomar, CFHT, & INT). We examine the radial (in-plane) and vertical (extraplanar) distributions of resolved stars as a function of stellar age and metallicity by tracking changes in the color-magnitude diagram of face-on and edge-on galaxies. Our data show, that the scale length and height of a stellar population increases with age, with the oldest detected stellar populations identified at a large galactocentric radius or extraplanar height, out to typically a few kpc. In the most massive of the studied galaxies there is evidence for a break in number density and color gradients of evolved stars, which plausibly correspond to the thick disk and halo components of the galaxies. The ratio of intermediate-age to old stars in the outermost fields correlate with the gas fraction, while relative sizes of the thick-to-thin disks anticorrelate with galactic circular velocity.
