Predicting the macroscopic permeability of porous media is critical in various scientific and engineering applications. This study proposes a novel model that combines Random Forest (RF) and rime-ice (RIME) optimization algorithm, denoted RIME-RF-RIME, to predict permeability based on six key features covering fluid phase dimensions, geometric characteristics, surrounding phase permeability, and media porosity.

The study "A genre analysis of abstracts of MA theses in English Linguistics" explores to what extent the Vietnamese learners of English as a foreign language (EFL) apply the knowledge that they have formally learned in the Writing and the Doing scientific research courses to writing their MA graduation theses; the focus is on the abstract. From the perspective of genre analysis, this study aims to describe the structural features of this genre. Data for the investigation is 30 abstracts bounded in the master theses written in English by Vietnamese learners.

This study explores if English videos on Facebook can improve speaking skills for freshmen struggling with English. We will divide freshmen into groups: one exposed to curated English videos on Facebook and another with no intervention. Both groups will take speaking tests before and after. By analyzing these tests, we aim to see if the Facebook group improves their fluency, vocabulary, and pronunciation, promoting better English proficiency.

Prolyl endopeptidase (PEP) is a proline-specific oligopepti-dase with a reported effect on learning and memory in dif-ferent rat model systems. Using the astroglioma cell line U343,PEP expression was reduced by an antisense technique. Measuring different second-messenger concen-trations revealed an inverse correlation between inositol 1,4,5-triphosphate [Ins(1,4,5)P3] concentration and PEP expression in the generated antisense cell lines. However,no effect on cAMP generation was observed.

To learn about the correlation between allostery and ligand binding of the Tet repressor (TetR) we analyzed the effect of mutations in the DNA read-ing head–core interface on the effector specific TetR i2 variant. The same mutations in these subdomains can lead to completely different activities, e.g. the V99G exchange in the wild-type leads to corepression by 4-ddma-atc without altering DNA binding. However, in TetR i2 it leads to 4-ddma-atc dependent repression in combination with reduced DNA binding in the absence of effector. ...

To facilitate the process of proteindesign and learn the basic rules that control the structure and stability of proteins, combinatorial methods have been developed to select or screen proteins with desired properties from libraries of mutants. One such method uses phage-display and proteo-lysis to select stably folded proteins. This method does not rely on specific properties of proteins for selection. There-fore, in principle it can be applied to any protein.

The newly emerging field of systems biology involves a judicious interplay between high-throughput ‘wet’ experimentation, computational modelling and technology development, coupled to the world of ideas and theory. This interplay involves iterative cycles, such that systems biology is not at all confined to hypothesis-dependent studies, with intelligent, principled, hypothesis-generating studies being of high importance and consequently very far from aimless fishing expeditions.

Mitotic chromosome structure depends on the chromosomal condensin complex. Without condensin, metaphase chromosomes remain undercondensed and lack structural stability. We have asked where along budding yeast chromosomes the condensin complex associates, and what we can learn from its binding pattern about the mechanism of chromosome condensation.
