The roles of tectonics and climate in the global increased erosion rates during the Quaternary have been the subject of active debate. The Three Rivers Region, strongly influenced by continental convergence between India and Eurasia and change in Asian monsoon climate, is an ideal place to study the interactions between tectonics and surface processes. Here we report new apatite (U-Th)/He data from an elevation transect that reveal a phase of rapid exhumation since ∼2.6 Ma in the Dulong batholith in the central Three Rivers Region, southeastern Tibetan Plateau. Based on stream profile analysis and compiled thermochronological data in the region, we demonstrate that the tectonic uplift caused by the high-strain at the corner of Indian-Eurasia convergence is responsible for the enhanced exhumation in the central Three Rivers Region in the Quaternary. Our new results highlight that the continuous plate convergence towards the plateau interior has dominated the uplift and deformation in the southeastern Tibet in the Quaternary.

Introduction The Journal of Morphological Sciences (JMS), the official journal of the Brazilian Society of Anatomy, is an interesting option for researchers to publish in the field of morphology. It includes articles that cover a wide variety of topics, such as gross and microscopic human and animal anatomy, embryology, cell and molecular biology, clinical cases and reviews. We aimed to perform a bibliometric study to analyze the profile of JMS publications from 2000 to 2017, in order to understand in depth the origins of the researches and the subject of the manuscripts published in this journal. Material and Methods This is a descriptive bibliographical review research, with a bibliometric analysis of the scientific production of the JMS between 2000 and 2017. A total of 894 publications were analyzed, and they were distributed in 63 issues and organized into 18 volumes. Three groups of information were considered: a) “identification of the published articles;” b) “origin and authorship of the published articles;” and c) “research subject in the published articles.” Results Most of the published manuscripts were original articles (72.5%) and their subjects were mainly microscopic animal anatomy (27%) and gross human anatomy (26.6%). A total 63.3% of the manuscripts involved at least one Brazilian institution, and 59.4% of those were public institutions. Conclusion This manuscript provides an important contribution to those who are publishing in the JMS, since the authors can find a great deal of information on the quality of the science that is being published in the journal, as well as demographic information on authors and institutions.

Assessing the reliability of computer software has been an active area of research in computer science for the past twenty years. To date, well over a hundred probability models for software reliability have been proposed. These models have been motivated by seemingly unrelated arguments and have been the subject of active debate and discussion. In the meantime, the search for an ideal model continues to be pursued. The purpose of this paper is to point out that practically all the proposed models for software reliability are special cases of self-exciting point processes. This perspective unifies the very diverse approaches to modeling reliability growth and provides a common structure under which problems of software reliability can be discussed.

This article considers the remnants of Russian ritual practices surrounding houses in the Priangun’ie region of China. This region was populated by Russians from the late 19th century on. A large group of immigrants (Russian, Tungus and Buriat) immigrated there from the Transbaikal region of Russia after the establishment of Soviet rule in the early 20th century. The paper examines what remains of Russian traditional practices, how they have been blended with native Chinese traditions, and adapted over time to reflect intermarriage between people of Chinese or Tungus and Russian descent.

<p>The SE Tibetan Plateau has extensive broad, low-relief, high-elevation surfaces perched above deep valleys, as well as in the headwaters of the three rivers (the Salween, the Mekong, and the Yangtze). However, understanding the presence of these low-relief surfaces is a long-standing challenge because their formation process remains highly debated. While alternate mechanisms have been proposed to explain the low-relief surface formation in this setting (e.g., drainage-area loss mechanism due to horizontal advection; Yang et al., 2015, Nature), a long-standing hypothesis for the formation of low-relief surfaces is by a step change in uplift and incision into a pre-existing, low-relief surface (Clark et al., 2006, JGR; Whipple et al., 2017, Geology).</p><p>The morphology of low-relief surfaces in the SE Tibetan Plateau is largely consistent with formation by a step change in uplift, but one problem with this model is that low-relief surfaces formed by a step change in uplift are relatively short-lived, since they are incised and steepened by erosion, which sweeps upstream at the response time of mountain ranges (in the order of several million years). Using a landscape evolution model that combines erosion, sediment transport and deposition processes (Yuan et al., 2019, JGR), we demonstrate that propagating uplift form large parallel rivers, with broad low-relief, high-elevation interfluves that persist for tens to hundreds of million years, consistent with various dated ages. These low-relief surfaces can be long-lived because the drainage areas in these interfluves are insufficient to keep up with rapid incision of the large parallel mainstem rivers. Our simulated features match various observations in the SE Tibetan Plateau: (i) low-relief surfaces are approximately co-planar in headwaters, and decrease in elevation smoothly from northwest to southeast across the plateau margin; (ii) χ-elevation plots of the mainstem rivers are convex; (iii) low-relief surfaces have low erosion rates; and (iv) erosion rates are high in the mainstem rivers at the propagating margin.</p>

AbstractAs a complement to life histories authored by many researchers of Maya bones, this study narrates death histories. The latter entails detection of perimortem and postmortem changes to decedents' bodies, followed by translation of these changes' encoded meanings. Biographical analysis of body parts and the buildings in which they are situated facilitates such an endeavor. Past investigations of partibility have focused on protracted processing of noble and royal bodies as a means to reconstitute decedents' identities. Commoners' burials, however, have received far less attention. Consequently, it is difficult to determine if partible practices differ according to or transcend social class. To address this lacuna, a multiscalar frame is applied to a burial sample comprised of decedents from varied social settings in the Three Rivers region, northwestern Belize. Identification of widely shared practices related to the becoming and venerating of ancestors offers a springboard for examining particulars within patterns. Scaling down, commoner burials unearthed at the minor center RB-11 are summarized and special attention is paid to the death history of Individual 71. This decedent's intentionally fragmented body reflects general thinking about ancestors as partible and dividual persons. Yet, certain attributes of Individual 71's burial are unique to the sample as a whole, which demonstrates how social class, circumstance, and individual life history are also instrumental in the reformation of ancestorhood.

AbstractIn the past decade, several considerable achievements have been reached in the field of Galactic microquasars, especially in light of the extreme variability of their relativistic jets. These jets are now known to exist in at least three different flavours: the self absorbed compact jets in the hard state, the transient and discrete ejection events associated with the state transitions, and the emission associated with the interaction of the jets on the interstellar medium. Although their phenomenology is now starting to be rather well established, their emission and contribution to the total energy budget of microquasars is still the subject of active debate. One way to probe the origin of their emission at various wavelengths is to use the broadband correlations that may exist between different energy domains. Initiated in the radio and X-ray ranges, these broadband flux correlations now include optical and infrared observations of black hole candidates and also neutron star systems. In this review, I also outline the current observational status of the emission of relativistic jets at high energy.
