A new rapid and sensitive method, the single vertical spin autoprofiler (VAP), has been developed for quantitative profiling of the major plasma lipoproteins. The method involves a combination of single vertical spin separation of plasma and continuous on-line analysis of cholesterol. Plasma lipoproteins are first separated by a 45-min spin in a vertical rotor, after which the amount of cholest...

1.1. Point 1: Cited Papers. Gunnam et al. claim that we did not cite correctly their work [2] and refer to other four publications of their own to provide further explanation. Actually the introductory section of our work [3] aims at providing an overview of the state-of-the-art architectures on the subject. The five works by Gunnam et al. basically propose the same LDPC architecture where the ...

The contribution of very low density lipoproteins (VLDL) and intermediate density lipoproteins (IDL) to various low density lipoprotein (LDL) subfractions was examined in three normal subjects and two with familial combined hyperlipidemia. Autologous VLDL + IDL (d less than 1.019 g/ml) or VLDL only (d less than 1.006 g/ml; one subject only) were isolated by sequential ultracentrifugation, iodin...

We derive asymptotic expressions for the average distance distributions in ensembles of irregular low-density paritycheck (LDPC) codes. The ensembles are defined by matrices with given profiles of column and row sums.

본 논문은 IEEE 802.16e 표준에서 제시한 효율적인 부호화가 가능한 low-density parity-check (LDPC) 부호에 대하여, 두 가지 대표적인 LDPC 부호의 복호 알고리즘을 기반으로 각각 체크 노드 분할을 이용한 변형된 새로운 복호 방법을 적용하여 수렴 속도 개선을 확인한다. 이는 적은 반복으로 동일한 복호 성능을 보장할 수 있기 때문에, 복호 과정에서 연산의 복잡도를 절반 가량 줄일 수 있는 장점을 갖는다. 또한 IEEE 802.16e 표준에서 제시된 LDPC 부호에 성능과 구현 측면에서 가장 적합한 체크 노드 분할 방법으로 비중복 분할 방법을 제안한다. 새로운 복호 알고리즘은 신뢰할 만한 정보의 복원을 보장하면서도 계산 복잡도를 줄일 수 있다는 의미에서 실제 무선 통신 시스...
