Laparoscopic liver resection (LLR) is currently an acceptable approach to surgery in select patients. The correlation between the intraoperative position and presence of gravity-dependent atelectasis (GDA) has been well discussed. However, LLR performed left half lateral position, relationship this GDA remains unclear. We evaluated extent which affects GDA. Furthermore, univariate multivariate ...
Purpose: It is unknown how use and outcome of laparoscopic liver resection (LLR) compare between high-volume centres (HV) low-medium volume (LMV). This study aimed to LLR according surgical difficulty in three leading European HV twenty Dutch LMV. Method: An international, retrospective multicentre cohort including data from LMV January 2011 December 2016. are defined by performing >50 annually...
Section 5.0 of DO-178B/ED-12B explains that when Source Code is generated directly from high-level requirements (HLR), then the high-level requirements are also considered lowlevel requirements (LLR), and the guidelines for low-level requirements also apply. This part of section 5.0 addresses the case where the system-level requirements are "directly" highly refined (i.e., created in one refine...
The lower limb rehabilitation robot is an application of robotic technology for stroke people with lower limb disabilities. A new applicable and effective sitting/lying lower limb rehabilitation robot (LLR-Ro) is proposed, which has the mechanical limit protection, the electrical limit protection, and the software protection to prevent the patient from the secondary damage. Meanwhile, as a new ...
Although minor laparoscopic liver resections (LLRs) appear as standardized procedures, major LLRs are still limited to few expert teams. The aim of this study was to report the combined data of 18 international centers performing major LLR. Variables evaluated were number and type of LLR, surgical indications, number of synchronous colorectal resections, details on technical points, conversion ...
The log-likelihood ratio (LLR) and the chi-squared distribution based test statistics have been proposed in the literature for performing statistical analysis of key recovery attacks on block ciphers. A limitation of the LLR test statistic is that its application requires the full knowledge of the corresponding distribution. Previous work using the chi-squared approach required approximating th...
Accurate control of body posture is enforced by a multitude of corrective actions operating over a range of time scales. The earliest correction is the short-latency reflex (SLR) which occurs between 20-45 ms following a sudden displacement of the limb and is generated entirely by spinal circuits. In contrast, voluntary reactions are generated by a highly distributed network but at a significan...
Bit-interleaved coded modulation with iterative detection for MIMO systems demands an efficient APP detector that delivers soft information about the coded bits. The list-sequential detector is a reduced-complexity approximation to an exhaustive APP detector. It uses a tree search employing the stack algorithm to find dominant terms of the log-likelihood ratio (LLR). We show how incomplete tree...
