MATHEMATICAL MODELS FOR CHROMOSOMAL INVERSIONS [PDF]

Genetics, 1967
INCE a formal characterization of the nature of inversions has not been made to date, this paper will hypothesize mathematical models for the occurrence of inversions of various lengths, obtain the associated probability distributions of lengths and midpoints of chromosomal inversions, and compare the hypothesized models with two sets of data.

Inverzná optimalizácia v obehových rozvrhoch autobusov [PDF]

Trendy v podnikání, 2016
In this paper we study nontraditional model which can occur for the bus scheduling problems. It is motivated by answer to the question: At what minimum shortening of the driving time in some sections of the transport network will happen that an existing ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Inverse modeling of European CH4 emissions: sensitivity to the observational network [PDF]

, 2009
Inverse modeling is widely employed to provide “top-down” emission estimates using atmospheric measurements. Here, we analyze the dependence of derived CH4 emissions on the sampling frequency and density of the observational surface network, using the ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

A REE Inverse Model From Bulk Distribution Coefficients and Boundary Conditions: Results for Shield and Rejuvenated Stage Hawaiian Volcanoes

Geochemistry, Geophysics, Geosystems
A major challenge in mantle geochemistry is determining the source composition and melt fraction involved in melting. We provide a new Rare‐Earth Element (REE) inverse model that provides source concentration, source and melt mineral modes, and melt ...

Trajectory Control of Flexible Manipulators Using Forward and Inverse Models with Neural Networks

Vibration
This study explores trajectory control in flexible manipulators using neural-network-based forward and inverse modeling. Unlike traditional approaches that enhance precision by increasing structural rigidity—often at the cost of added weight and energy ...

An Inverse Model for Raindrop Size Distribution Retrieval with Polarimetric Variables

Remote Sensing, 2018
This paper proposes an inverse model for raindrop size distribution (DSD) retrieval with polarimetric radar variables. In this method, a forward operator is first developed based on the simulations of monodisperse raindrops using a T-matrix method, and ...
