TLDR
The provided compressed bitstreams were uncompressed using provided software and the resulting sequences were compared to the original ones in terms of PSNR and it seems that last frames from some cameras give significantly worse PSNR than the rest of frames.
Abstract
The provided compressed bitstreams were uncompressed using provided software and the resulting sequences were compared to the original ones in terms of PSNR. Additionally, the sequence Ballroom was compressed using the provided software. Resulting bitstreams were processed as the ones provided by Sejong/ETRI to verify the whole chain of coding and decoding. The results obtained at Poznań University of Technology are included in the accompanying Excel file. They are the same as the ones provided by Sejong/ETRI, except for sequences Race1 and Flamenco2 results. The results for them are slightly worse than the ones presented by Sejong/ETRI. The difference is less than 0.05 dB. It seems that last frames from some cameras give significantly worse PSNR (about 10dB less than the rest of frames). The cause of this difference is unknown.

Plant-based proteinaceous snacks: Effect of fermentation and ultrasonication on end-product characteristics.

TL;DR: In this article, the authors developed a sufficient technology to improve sensory, textural, physical, and microbiological properties of peas snacks using solid-state fermentation (SSF) and submerged fermentation (SMF) with two different lactic acid bacteria (LAB) strains (Lactobacillus casei LUHS210 and Lactebacillus uvarum LUHS245) for 24 hr and ultrasonication (10, 20, and 30 min).

Deposition of Fluorescently Tagged Lysozyme on Contact Lenses in a Physiological Blink Model.

TL;DR: It may be beneficial to design CL materials with differing surface properties for the front and back surfaces of the CL to enhance interactions with the tear film and ocular surface.

Topic maps as indexing tools in e-learning: bridging theoretical and practical gaps between information retrieval and educational psychology

TL;DR: This paper describes an empirical study investigating graduate learners' use of topic map indexing technologies to browse a neo-corpus of annotated essays, posits that theories of cognitive information retrieval can best formalise abstract notions of learner cognitions like task understanding and self-regulated learning in the context of navigation of large online corpora.

Shift-And-Decorrelate Lifting: CAMRA for Lossless Intra Frame CFA Video Compression

TL;DR: This letter improves lossless intra-frame compression of color filter array (CFA) video based on Camera-Aware Multi-Resolution Analysis (CAMRA), showing that the chrominance components shared by LH and HL subbands of LeGall 5/3 wavelet transform are misaligned, negatively impacting the coding efficiency.
