The clinical courseamong these patients was similar to that described for patients with KoreanHemorrhagic Fever, Nephropathica Epidemica of Scandanavia and Hemor-rhagic Fever with Renal Syndrome of the U.S.S.R. The overall mortalitywas 11.2%. Sera obtaincd from some of these patients as well as frompatients admitted to the First Attached Hospital of Hubei Provincial Me-dical College were tested against an antigen associated with Korean He-morrhagic Fever and showed exceedingly high antibody titers.

Most often, such interactions are exploitative for the indigenous communities. Besides this, the development induced displacement escalate the fear of loss of "cultural practices" among the indigenous peoples. The "official" argument often confines to the fact that the people are displaced with better facilities to a place few kilometres away from the original habitat. Such an argument forces to establish harmony between development and the displaced and ignores cultural rights and customary boundaries. In such cases, indigenous peoples negotiate for the protection of cultural rights with the corporate establishments and statutory bodies using a variety of means. This idea is explored in the context of the resistance movement organized by the indigenous Kondhs of Niyamgiri region of Odisha, India.展开更多
This paper relates to the statement that the so-called “Little Ice Age” (RCC 6: 1.350-1.800 A.D.) represents—besides the 8k-Event (8.200-8.000 yr cal. B.P.)—the fastest and strongest onset in Holocene History [1]....This paper relates to the statement that the so-called “Little Ice Age” (RCC 6: 1.350-1.800 A.D.) represents—besides the 8k-Event (8.200-8.000 yr cal. B.P.)—the fastest and strongest onset in Holocene History [1]. Its intention focuses on the correlation of interplaying natural processes (i.e. solar energy variation, aerosols, oceanic currents, volcanism as part of plate tectonics, heat flow) with social/political evidence through the time-span of Peoples’ Migration until Industrial Revolution (3rd-18th Century). The time-span comprises the cool/wet/respectively dry climate phase of the P.M. (260-550), a Climate Optimum (600-1.100 A.D.) owning a final Thermal Maximum (1.100-1.260 A.D.) and the “little Ice Age” (1.350-1.800 A.D.), the latter intercalated by the Spörer Minimum (1.460-1.550 A.D.) and the Maunder Minimum (1.650-1.720 A.D.). Thereby, an average temperature difference of 1.0°C - 2.0°C seems sufficient for incising climatic/cultural consequences [2]. It has become obvious that a Climate Optimum primarily provides constructive life conditions;however with a problematic final as the following “Effect-Chain” tells: balanced agricultural/cultural population growth → rich harvests → satisfying nourishment → health, encouragement → overpopulation under favorable materialistic conditions → increasing stress → lack of food, high prices → revolts → migration. In contrast, cool/wet/resp. dry conditions originate destructive/depressive conditions (see Peoples’ Migration) which initiate the following “Effect Chain”: bad agricultural conditions → poor/no harvesting → famine → disease, growing death rate → social, political revolts, wars → human cruelties with psychic/religious background (inquisition, witch-combustion → general chaos (30 yr-war) → death, migration (maritime endeavors, colonization). Furthermore, it should be stressed that volcanic aerosols play besides the solar influx variation—an important role on climate/cultural change [3]. However, the effects of oceanic currents’ heat flow of Mid-Oceanic Ridges and Hot Spots, as well as Earth-Magnetism and Sun/Earth Geometry are poorly understood in this context (Example: Iceland as hot spot situated on the Mid-Atlantic Ridge having been working since 40 Ma). The Chapter-introducing citations play a challenging role in regard to Science Criticism and touch the so-called 95% Confidence line (accepted realm of causal interrelation and according recommendation to Society [4]).展开更多

Discussing autobiographies or indigenous biographies is still an uncommon endeavor, even in our field of Letters/Liberal Arts or in Indigenous Ethnology. However, since the beginning of the process of reclaiming the lands that once belonged to them, the indigenous Peoples have been producing autobiographical narratives, demonstrating how this genre of text production--traditionally linked to the development of the Western individual---can constitute and be appropriated in different Amerindian translations. It is fi'om this perspective that I intend to present a discussion about those text productions, analyzing what their collective signatures express, and how their proper names are constructed and signified on behalf of the group.展开更多

Despite advancements in optical detection capabilities through imaging systems, including spectral, polarization, and infrared technologies, there is still a lack of effective real-time method for accurately detecting small-size and high-efficient camouflaged people in complex real-world scenes. Here, this study proposes a snapshot multispectral image-based camouflaged detection model, multispectral YOLO(MS-YOLO), which utilizes the SPD-Conv and Sim AM modules to effectively represent targets and suppress background interference by exploiting the spatial-spectral target information. Besides, the study constructs the first real-shot multispectral camouflaged people dataset(MSCPD), which encompasses diverse scenes, target scales, and attitudes. To minimize information redundancy, MS-YOLO selects an optimal subset of 12 bands with strong feature representation and minimal inter-band correlation as input. Through experiments on the MSCPD, MS-YOLO achieves a mean Average Precision of 94.31% and real-time detection at 65 frames per second, which confirms the effectiveness and efficiency of our method in detecting camouflaged people in various typical desert and forest scenes. Our approach offers valuable support to improve the perception capabilities of unmanned aerial vehicles in detecting enemy forces and rescuing personnel in battlefield.展开更多
