新生代早期(约45 Ma),印度板块在经历了长时期的北向漂移后终与欧亚大陆碰撞。其后,以印度洋的扩张作用为驱动力,印度板块持续向欧亚大陆推挤,使造山带地区产生大规模的陆壳缩短,造就了壮观的世界屋脊——青藏高原。70年代中期。

Extensive paleomagnetic studies in the Yangtze Block of South China has been performed since the 1980s, and the Phanerozoic APW (apparent polar wander)path has been established based on a large amount of data obtained. However, the Huanan Block in southeastern region still remains unknown paleomagnetically. In order to further understand the plate tectonic patterns and evolutional history prio Mesozoic collision of the

A tentative Apparent Polar Wander (APW) path for the Shan-Thai-Malay Block (STMB), SW Yunnan, China, is constructed based on the paleomagnetic results from the Upper Devonian (D=201.9°, I=31.3°, des=13.3°, k=5.7, N=25 samples, Plong=245.1°E, Plat=41.8°N), Lower Permian (D=247.0°, I=46.0°, a95=10.0°, k=8.5, N=28 samples, Plong=223.7°E, Plato6.8°N), and Middle Triassic (D=96.0°, I=-28.9°, a95=10.2°, k=8.1, N=28 samples, Plong=200.8°E, Plat=11.7°N), as well as the Upper Silurian published earlier. These results were isolated from high temperature components and passed fold tests. The APW path for the STMB resembles neither that of the Yangtze nor the North China blocks. However, the change of paleolatitudes of the STMB could be correlated with that of Australia, implying that they might be closely spatially welded during the Paleozoic, as suggested by geological evidence.

Anisotropic edge enhancement is simulated using a spiral phase plate （SPP） in optical scanning holography （OSH）. We propose to use a delta function and an SPP as the pupil functions to realize anisotropic edge enhancement. The interference of these two pupils is used to two-dimensionally scan an object to record its edge-only information. This is done in three ways： first, by shifting the SPP, second, by using two offset SPPs of same charge, and finally, by using two oppositely charged SPPs. Our computer simulations show the capability of selectively enhancing the edges of a given obiect.

Peripheral neuropathy(PN) is a multifarious disorder that is caused by damage to the peripheral nerves. Although the symptoms of PN vary with the etiology, most cases are characterized by impaired tactile and proprioceptive sensation that progresses in a distal to proximal manner. Balance also tends to deteriorate as the disorder becomes more severe, and those afflicted are substantially more likely to fall while walking compared with those who are healthy. Most patients with PN walk more cautiously and with greater stride variability than age-matched controls, but the majority of their falls occur when they must react to a perturbation such as a slippery or uneven surface. The purpose of this study was to first describe the role of somatosensory feedback in the control of posture and then discuss how that relationship is typically affected by the most common types of PN. A comprehensive review of the scientific literature was conducted using MEDLINE, and the relevant information was synthesized. The evidence indicates that the proprioceptive feedback that is conveyed primarily through larger type I afferents is important for postural control. However, the evidence indicates that the tactile feedback communicated through smaller type II afferents is particularly critical to the maintenance of balance. Many forms of PN often lead to chronic tactile desensitization in the soles of the feet and, although the central nervous system seems to adapt to this smaller type II afferent dysfunction by relying on more larger type I afferent reflex loops, the result is still decreased stability. We propose a model that is intended both to help explain the relationship between stability and the smaller type II afferent and the larger type I afferent feedback that may be impaired by PN and to assist in the development of pertinent rehabilitative interventions.
