One-pass adaptive universal vector quantization [PDF]

open access: yes, 1994
The authors introduce a one-pass adaptive universal quantization technique for real, bounded alphabet, stationary sources. The algorithm is set on line without any prior knowledge of the statistics of the sources which it might encounter and ...

Evaluation de la productivité et de la mortalité de la poule locale sur le plateau du Sankaran, Faranah, Guinée, en 1993-1994

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1997
Cet article traite de la productivité et de la mortalité de la poule de race locale en milieu villageois (plateau du Sankaran). La productivité de cette poule était très modeste, caractérisée par le nombre d'œufs par couvée (10,05 + ou - 0,15) et le ...

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

What does it take to evolve behaviorally complex organisms? [PDF]

open access: yes, 2001
What genotypic features explain the evolvability of organisms that have to accomplish many different tasks? The genotype of behaviorally complex organisms may be more likely to encode modular neural architectures because neural modules dedicated to ...

An MCMC Approach to Universal Lossy Compression of Analog Sources

open access: yes, 2011
Motivated by the Markov chain Monte Carlo (MCMC) approach to the compression of discrete sources developed by Jalali and Weissman, we propose a lossy compression algorithm for analog sources that relies on a finite reproduction alphabet, which grows with
