Downlink Space–Time Spreading Using Interference Rejection Codes
No full textIn this paper, the authors will investigate the performance of a loosely synchronized (LS) code-based space–time spreading (STS) scheme in comparison to that of classic Walsh code and pseudonoise code-based STS when communicating over dispersive Nakagami-m multipath channels. Closed-form formulas are derived for characterizing the bit-error-rate performance as a function of the number of resolvable paths L and the number of users K. Our numerical results suggest that the employment of LS code-based STS scheme is beneficial in a low-user-load and low-dispersion channel scenario, where a near-single-user performance can be achieved without a multiuser detector. Index Terms—Code-division multiple access (CDMA), Gaussian approximation, interference-free window (IFW), large area synchronized (LAS) codes, loosely synchronized (LS) codes, Nakagami-m fading

A novel fabrication process to release a valveless micropump on a flexible substrate
No full textThis paper reports, for the first time, the design, fabrication and testing of a valveless micropump, entirely screen printed onto a flexible polyimide (Kapton) substrate by using sacrificial, polymer-structural and piezoelectric layers. The sacrificial layer, used to achieve a pump chamber and inlet/outlet channels, is thermally removed, analogous to a standard MEMS sacrificial process. Applying a sinusoidal AC voltage to the piezoelectric layer drives a flexible membrane which pumps liquid through the chamber. A maximum flow rate of 67µL/min can be achieved using a drive frequency of 600 kHz

Measurement (1 ♂, 3 ♀♀ ) Length of body (excluding wings): ♂ 34.0, ♀ 21.0 – 25.0; length of forewing: ♂ 37.0, ♀ 32.0 – 36.0; width of forewing: ♂ 11.5, ♀ 11.0 – 11.5; width of head (including eyes): ♂ 9.5, ♀ 7.5 – 8.0; width of pronotum (including pronotal collar): ♂ 11.5, ♀ 9.5 – 10.0; width of mesonotum: ♂ 10.0, ♀ 8.0 – 9.0. Distribution China (Hainan and Yunnan). Etymology The specific name is derived from Latin ‘brevi’ and ‘dilata’ which refer to the relatively short uncal lobes of pygofer. Remarks This new species is very similar to S. watanabei in external morphology, but it can be distinguished from the latter and other species of Semia by the relatively short uncal lobes of male pygofer.Published as part of Yang, Mingsheng & Wei, Cong, 2014, New species of the cicada genus Semia Matsumura (Hemiptera: Cicadidae) from China and a phylogeny of Semia spp. and their relatives based on molecular data, pp. 2307-2323 in Journal of Natural History (J.
