Background and purpose: Identifying cerebral microhemorrhage burden can aid in the diagnosis and management of traumatic brain injury, stroke, hypertension, and cerebral amyloid angiopathy. MR imaging susceptibility-based methods are more sensitive than CT for detecting cerebral microhemorrhage, but methods other than quantitative susceptibility m...

We describe diachronic evidence of moisture reduction and its consequences for coastal irrigation, agriculture, and settlement at Quebrada Tacahuay, a large drainage south of the Osmore River in far southern Peru. These observations are the first for a drainage of this size and for one with occupation spanning over 12,000 years for southern Peru. F...

Purpose of Review Review MRI neuroimaging techniques which utilize tissue susceptibility. Recent Findings The evaluation of neuropathologies using MRI methods that leverage tissue susceptibility have become standard practice, especially to detect blood products or mineralization. Additionally, emerging MRI techniques have the ability to provide ne...

While brain connectivity analyses have been demonstrated to identify ill patients for a number of diseases, their ability to predict cognitive impairment after brain injury is not well established. Traditional post brain injury models, such as stroke, are limited for this evaluation because pre-injury brain connectivity patterns are infrequently av...

The theory of plate tectonics contends that the continental plates occupied by humanity are in motion. The hypothesis of agrarian collapse (HAC) holds that gradual, as well as seismic, earth movement can induce ground slope change and modify land-to-sea level relationships, thereby altering the distribution of surface and subsurface runoff, which c...

Past and present el nino expressions in southern peru

Before the Inca reigned, two empires held sway over the central Andes from anno Domini 600 to 1000: the Wari empire to the north ruled much of Peru, and Tiwanaku to the south reigned in Bolivia. Face-to-face contact came when both colonized the Moquegua Valley sierra in southern Peru. The state-sponsored Wari incursion, described here, entailed lar...

En el presente trabajo se analiza el rol de los encuentros y reuniones de diversa escala en la colonia wari de Moquegua, Perú (600-1000d.C.). El papel de los festines cambió sustancialmente con la expansión de las entidades políticas Wari y Tiwanaku, e involucró múltiples lugares y numerosos tipos de congregaciones. La evidencia resulta de excavaci...

In the desert region around the coastal city of Ilo, the great southern Peru earthquake of June 23, 2001 (8.2-8.4 moment magnitude), produced intense and widespread ground-failure effects. These effects included abundant landslides, pervasive ground cracking, microfracturing of surficial hillslope materials, collapse of drainage banks over long str...

Previous work throughout the Ilo region of south coastal Peru has documented the existence of flood and debris-flow deposits produced by two El Niño events evidently much more severe than any in recent history. These two events have been dated to ca. AD 1300–1400 and AD 1607–08. The Late Pleistocene to Holocene record of older sedimentary deposits...

The report by R. Shady Solis, J. Haas, and W. Creamer on the early monumental Peruvian site of Caral (Supe Valley) provides important data about early complex society in the Andes (“Dating Caral, a preceramic site in the Supe Valley on the central coast of Peru,” 27 Apr., p. 723). However, the

In modeling the colonization of the Americas, Anderson and Gillam (2000) employ size estimates for vanguard forager bands that are of dubious reproductive viability in light of human incest prohibitions and variable sex ratios at birth.

The archaeological site of Quebrada Tacahuay, Peru, dates to 12,700 to 12,500 calibrated years before the present (10,770 to 10,530 carbon-14 years before the present). It contains some of the oldest evidence of maritime-based economic activity in the New World. Recovered materials include a hearth, lithic cutting tools and flakes, and abundant pro...

Abandoned farm land is a prominent feature on the Andean landscape. At the spring-fed canal system of Carrizal, on the desert coast of Peru, prehispanic, colonial, and recent abandonment conforms to two land-loss patterns. These are associated with change in natural hydrological conditions that should similarly affect other forms of irrigation agri...

A modern analogue for past convergent disasters.

The major intravalley canals of the Moche Valley in Peru built during the Late Intermediate Period (ca. 900–1400 A.C.) are analyzed for their engineering design content and design philosophy. An historical overview of the canals reveals successive abandonment of older, higher outlying canals in favor of near-river systems of lesser length. With thi...

Ongoing gradual uplift of the Pacific watershed of Peru results in water table subsidence. As a mechanical consequence, the form and use of embankment-bound fields evolve through a series of distinct stages. Conflicting interpretations arise as a consequence of different investigators having addressed field structures in different stages of evoluti...

Antithetical premises of a static versus dynamic Andean landscape produce contradictory interpretations of the Chicama-Moche Intervalley Canal. On a static landscape, inoperable canal gradients must be explained by social parameters such as poor surveying or construction techniques. The paradigm of Plate Tectonics and evidence of ongoing crustal co...

Of the many canal systems of the Chimu empire the Chicama-Moche Intervalley (La Cumbre) Canal connecting the Chicama and Moche valleys represents the highest level of technical achievement. This paper examines the engineering skills of the Chimu as revealed by computer analysis of the open channel flow design techniques they utilized. Analysis of a...

Mud bricks in Huaca del Sol and Huaca de la Luna differ in soil composition, dimensions, mold marks, and makers' marks. The differences reflect conditions of brick production and use, and some variables are chronologically significant. This paper discusses the archaeological significance of adobes in these platform mounds, located on the south side...

Prehistoric construction projects in the Moche Valley required the mobilization and coordination of very large numbers of individuals. It is thought that workers were mobilized by means of labor tax obligations, and large projects were subdivided into repetitive tasks executed by distinct parties of workmen drawn from separate communities.

I have discussed Chan Chan in terms of its political and economic characteristics because state organization had a pervasive impact on the growth and structure of the settlement. In this sense the capital of Chimor resembles Cuzco the Inca capital. Both metropolitan centers served as seats of Andean empires governed by noble classes headed by membe...

Seeds, fiber samples, and boll parts recovered from 4 pre-ceramic sites in the Ancon-Chillon area of Peru were compared with those of living forms, both wild and cultivated, collected from the coastal areas of Ecuador and Peru. All the living forms belong to the species, Gossypium barbadense L., and it was concluded that the archaeological cotton b...

The large preceramic site of Aspero, on the central Peruvian coast, was explored in the past by Uhle and by Willey and Corbett; however, these investigators did not recognize the presence of sizable artificial platform mounds or "corporate labor structures" at the site. In spite of its preceramic status, Aspero was a sedentary community, and the co...

Cotton remains from four archeological sites in central coastal Peru, representing a time sequence from about 2500 to 1000 B.C., were compared with similar materials obtained from living wild and cultivated forms of Gossypium barbadense L. The comparison revealed that the archeological cotton samples were primitive forms of Gossypium barbadense, di...

A series of basic changes in subsistence patterns affected the prehistoric population of the Peruvian desert coast. A shift from hunting-gathering to fishing and then to farming called for the exploitation of new and different resource complexes. After examining the nature of these complexes and reviewing the archaeological record of the Ancon-Chil...

Settlement pattern research was introduced to Peruvian archaeology by Gordon R. Willey 2 decades ago. A critical review of this pioneering work points up a basic problem in the structure of analysis. The problem is generated by the use of a simple site taxonomy that is insensitive to the range of human activities that went on at different settlemen...

On the coast of Peru farming in mahamaes or sunken gardens fed by ground water offers an alternative to canal irrigation. The possibility that mahamaes were influential during the early stages of farming is examined and rejected on theoretical and empirical grounds. The possible significance of farming in sunken gardens during later pre-Columbian t...

For the period of ca. 2500 to 1700 B.C. a three-phase sequence in the development of twined cotton textiles is outlined. The phases represent divisions of a gradual change from the use of single-warp twining to the use of plural-warp twining as revealed in recent excavation at five sites in the Ancon-Chillon area of coastal Peru.

Loma Lasca, a coastal site near the mouth of the Santa Valley, Peru, produced an abundance of large primary flakes. Investigation of the midden suggested that these were used for the scaling and cleaning of fish.
