In networking systems today data rates are increasing beyond 15Gb/s and yet the installed backplanes are made of low cost materials with losses in excess of 30dB at 7.5GHz. Standards, such as IEEE802.3ap-10GBASE-KR and OIFCEI25G, are specifying SerDes requirements for channels with 25dB loss at Nyquist and this has driven the development of SerDes with 4 or(More)
We construct explicit chain maps for the various Reidemeister moves, then prove that the compositions of chain maps associated to each side of each of Carter and Saito’s movie moves [7, 6] always agree. These calculations are greatly simplified by following arguments due to Bar-Natan and Khovanov, which ensure that the two compositions must agree, up to a(More)
When provided with fecal pellets from uninfected (control) rats and rats infected with the tapeworm Hymenolepis diminuta, more fed and starved (72 h) female and starved male Tenebrio molitor fed on fecal pellets from infected- than from control rats; compared to fecal pellets from controls rats, fed males avoided the infective fecal pellets. Uninfective and(More)
Tribolium castaneum and T. confusum were washed in HPLC-grade methanol, and the methanolic washes were analyzed by UV spectroscopy, reversed phase HPLC, and GC/MS. The methanolic washes from both species contained methyl-1,4-benzoquinone (MBQ) and ethyl-1,4-benzoquinone (EBQ). The amounts of MBQ recovered from the two species were not significantly(More)
Growing interest in 21 cm tomography has led to the design and construction of broadband radio interferometers with low noise, moderate angular resolution, high spectral resolution, and wide fields of view. With characteristics somewhat different from traditional radio instruments, these interferometers may require new calibration techniques in order to(More)
Acknowledgements Firstly I would like to express my gratitude to John Steele, my supervisor, for his guidance and assistance, and for the considerable time he has invested in checking my drafts, clarifying my prose, and especially in trying to make my seminar make some sense! A considerable number of members of the Mathematics Department have made available(More)
We are working on mapping multi-channel neural spike data, recordedfrom multiple cortical areas ofan owl monkey, to corresponding 3d monkey arm positions. In earlier work on this mapping task, we observed that continuous function approximotors (such as artificial neural networks) have diflculty in jointly estimating 36 arm positions for two distinct cases(More)
In this paper, we present a design for a wearable computational DSP system that alleviates the issues of a previous design and provides a much smaller and lower power solution for the overall BMI goals. The system first acquires the neural data through a high speed data bus in order to train and evaluate prediction models. Then it wirelessly transmits the(More)
In this paper, we present a design for a wearable DSP system that is capable of processing various neural-tomotor translation algorithms. The system first acquires the neural data through a high speed data bus in order to train and evaluate our prediction models. Then via a widely used protocol, the low-bandwidth output trajectory is wirelessly transmitted(More)
