Scale is a concept used to manage information about the real world and to summarize observations about complex phenomena that vary within space, time, or other dimensions. The ordering of phenomena according to scale enables human beings to store, recall, and analyze information about features that would otherwise be impossible to evaluate. The concept is essential to researchers of agricultura...

Introduction: Molecular interactions play an important role in the phenomenon and biological processes. In fact, any cellular biological process ranged from genetic replication to the production of various proteins to the transmission of neurological, hormonal, membrane involves collections of molecular interactions that occur continuously. Interference in each of these processes at every stage...

Markov state models (MSMs) have proven to be useful tools in simulating large and slowly-relaxing biological systems like proteins. MSMs model proteins through dynamics on a discrete-state energy landscape, allowing molecules to effectively sample large regions of phase space. In this work, we use aspects of MSMs to ask: is protein folding mechanistically robust? We first provide a definition o...

The apoptosis of cancer cells is associated with changes in the important cell properties including morphology, surface roughness and stiffness. Therefore, the changes in morphology and biophysical properties can be a good way of evaluating the anticancer activity of a drug. This study examined the effect of paclitaxel on the properties of Ishikawa and HeLa cells using atomic force microscopy (...

The planetary boundaries framework defines a safe operating space for humanity based on the intrinsic biophysical processes that regulate the stability of the Earth system. Here, we revise and update the planetary boundary framework, with a focus on the underpinning biophysical science, based on targeted input from expert research communities and on more general scientific advances over the pas...

Ecological restoration is an activity that ideally results in the return of an ecosystem to an undisturbed state. Ecosystem services are the benefits humans derive from ecosystems. The two have been joined to support growing environmental markets with the goal of creating restoration-based credits that can be bought and sold. However, the allure of these markets may be overshadowing shortcoming...

Empirical models are important tools for relating field-measured biophysical variables to remotely sensed data. Regression analysis has been a popular empirical method of linking these two types of data to estimate variables such as biomass, percent vegetation canopy cover, and bare soil. This study was conducted in a semi-arid rangeland ecosystem of Qazvin province, Iran. This paper presents t...

BACKGROUND/AIM Systemic isotretinoin has been widely considered an effective and safe medical treatment for severe and refractory acne for nearly 3 decades. However, it also appears to cause undesirable cutaneous side effects. The aim of this study was to prospectively measure biophysical parameters of skin function among patients with acne vulgaris before and after 3 months of isotretinoin the...
