Impacts of Residual Self-Interference, Hardware Impairment and Cascade Rayleigh Fading on the Performance of Full-Duplex Vehicle-to-Vehicle Relay Systems.

In practice, self-interference (SI) in full-duplex (FD) wireless communication systems cannot be completely eliminated due to imperfections in different factors, such as the SI channel estimation and hardware circuits. Therefore, residual SI (RSI) always exists in FD systems. In addition, hardware impairments (HIs) cannot be avoided in FD systems due to the non-ideal characteristics of electronic components.

A Life Course Perspective on the Wartime Migrations of Northern Vietnamese War Survivors.

Research addressing conflict and migration has made great strides in explaining the relationship between violence and migration. However, it commonly lacks individual-level data on exposure to war. We use survey data from the 2018 Vietnam Health and Aging Study to examine the associations between war-related violence exposure during the American War and the wartime migrations of northern Vietnamese war survivors.

Design and measurement in a study of war exposure, health, and aging: protocol for the Vietnam health and aging study.

Background: Survivors of war throughout the world experience illnesses and injuries that are crucial to understand, given the ongoing treatment and adaptation they demand. In developing countries like Vietnam, where population aging and chronic disease burdens are rapidly rising, aging populations have seen a disproportionate share of armed conflict and related casualties. This paper describes the Vietnam Health and Aging Study (VHAS), a unique resource for investigating mechanisms of association between diverse exposures to armed conflict during the Vietnam War and multiple dimensions of older adult health among survivors of that war.

Levels of change in adolescent sexual behavior in three Asian cities.

Considerable change in the romantic and sexual behaviors of Asian young people may be occurring as traditionally Confucian societies modernize and increase outside contacts. This study explores the dimensions and context of this change in three sites at different stages in the process of modernization: Hanoi (early), Shanghai (intermediate), and Taipei (later stage). A survey was conducted of 17,016 males and females aged 15-24 in urban and rural settings in three large metropolitan areas.

Cervicothoracic spinal epidural cavernous hemangioma: case report and review of the literature.

Cavernous hemangiomas are vascular malformations that effect the central nervous system. This pathology is frequently encountered in the cerebral hemispheres, cerebellum, and brainstem. Cavernous hemangiomas, although usually solitary, may be associated with the same lesion in other parts of the central nervous system or other organ systems and may appear as sporadic or familial cases.
