Aim: The purpose of this study is to assess the benefit laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) given recurrence and future need transplantation (LT). Methods: Data on resections were gathered from Istituto di Ricovero e Cura a Carattere Scientifico-Istituto Mediterraneo per i Trapianti Terapie ad alta specializzazione (IRCCS-ISMETT) 2003-2021. A retrospective anal...

In this paper, we consider the Type-II Hybrid ARQ schemes with the LDPC codes having the rate of 0.5 through MIMO-OFDM Spatial Multiplexing (SM) schemes for high speed and high throughput transmission. MMSE nulling and MLD are used for the signal separation and detection method in SM. We also have used the channel estimation per subcarrier with MMSE criterion. The uncoded Hybrid ARQ schemes wit...

In this paper, we propose a successive interference cancellation (SIC) detector which utilises multiple feedback (MF) candidates for cancellation stages and a dynamic log-likelihoodratio (LLR)-based dynamic reliability ordering (RO) of the cancellation stages in a multiple-input multiple-output (MIMO) system. The proposed multi-feedback reliability-ordered SIC (MF-RO-SIC) detector’s performance...

This paper examines the task of Spoken Term Detection (STD) for the Chinese language. We propose to use Linear Logistic Regression (LLR) to combine various Chinese STD systems built with different decoding units, detection units, features and phone sets. In order to solve the missing-sample problem in STD system combination, side-information reflecting the reliability of the scores for fusion i...

This letter proposes an efficient and simple stopping criterion for turbo decoding, which is derived by observing the behavior of log-likelihood ratio (LLR) values. Based on the behavior, the proposed criterion counts the number of absolute LLR values less than a threshold and the number of hard decision 1’s in order to complete the iterative decoding procedure. Simulation results show that the...

The exact nonlinear loop gain of the belief propagation algorithm (BPA) in its log-likelihood ratio (LLR) formulation is computed. The nonlinear gains for regular lowdensity parity-check (LDPC) error correcting codes can be computed exactly using a simple formula. It is shown that in some neighborhood of the origin this gain is actually much smaller than the identity. Using a small-gain argumen...

Certain properties of optimal bitwise APP (A Posteriori Probability) decoding of binary linear block codes are studied. The focus is on the Probability Density Function (pdf) of the bit Log-Likelihood-Ratio (LLR). A general channel model with discrete (not necessarily binary) input and discrete or continuous output is considered. It is proved that under a set of mild conditions on the channel, ...

Presenter: Epameinondas Dogeas MD | University of Pittsburgh Medical Center Background: Laparoscopic liver resection (LLR) for colorectal cancer metastases (CRLM) is well-established with clinical short-term benefits, however data lacking on long-term (10 year) oncologic outcomes. Methods: A retrospective review a prospectively maintained database at single Western center was performed to ident...
