Relationship between perceived exertion during exercise and subsequent recovery measurements
Biology of Sport, 2016 The return towards resting homeostasis in the post-exercise period has the potential to represent the internal training load of the preceding exercise bout. However, the relative potential of metabolic and autonomic recovery measurements in this role has

FEBS Open Bio, EarlyView.The tumor microenvironment is a dynamic, multifaceted complex system of interdependent cellular, biochemical, and biophysical components. Three‐dimensional in vitro models of the tumor microenvironment enable a better understanding of these interactions and their impact on cancer progression and therapeutic resistance.

Channels of oxygen diffusion in single crystal rubrene revealed [PDF]
, 2016 Electronic devices made from organic materials have the potential to support a more ecologically friendly and affordable future. However, the ability to fabricate devices with well-defined and reproducible electrical and optical properties is hindered by the sensitivity to the presence of chemical impurities.

Hierarchical Fuel-Cell Airpath Control: an Efficiency-Aware MIMO Control Approach Combined with a Novel Constraint-Enforcing Reference Governor [PDF]
arXiv, 2023 This paper presents a hierarchical multivariable control and constraint management approach for an air supply system for a proton exchange membrane fuel cell (PEMFC) system. The control objectives are to track desired compressor mass airflow and cathode inlet pressure, maintain a minimum oxygen excess ratio (OER), and run the system at maximum net ...

Metabolic Consequences of Rheumatoid Arthritis
Arthritis Care &Research, EarlyView.Patients with rheumatoid arthritis (RA) may have metabolic disruption, which can contribute to adverse long‐term outcomes, for multiple reasons. Patients with RA appear to have a higher risk of sarcopenia, type 1 and type 2 diabetes mellitus, metabolic syndrome, and hypertension. Systemic inflammation in RA can cause a “lipid paradox,” with reduced low‐

Fetal oxygen delivery and consumption and blood gases in relation to gestational age [PDF]
arXiv, 2021 Fetal oxygen delivery and consumption and blood gases in relation to gestational age. Oxygen crosses the placenta by diffusion and placental permeability to O$_2$ is high. Thus, the fetus receives adequate amounts, but vascular Po$_2$ is much lower than after birth. Studies of sustained fetal hypoxemia and acute 40-45% hemorrhage show that hypoxemia is

Effects of excess or deficiency of oxygen content on the electronic structure of high-$T_C$ cuprates [PDF]
J. Supercond. Nov. Magn. (2013), 2013 Band structure calculations are presented for large supercells of Ba$_2$CuO$_4$ (BCO) with O-vacancies in planar or apic al positions, and of superoxygenated La$_2$CuO$_4$ (LCO) with oxygen interstitials in the La$_2$O$_2$ layers. It is foun d that apical oxygen vacancies in BCO act as electron dopants and makes the electronic structure similar to that

Advanced Engineering Materials, EarlyView.A novel approach for alloy development in laser powder bed fusion is introduced. Instead of producing massive samples of one composition at a time, prepressed powder bed samples produced from powder mixtures are processed. Guidelines for the selection of precursor powders are developed.

Effects of moderate-intensity exercise on diet-induced increase in resting oxygen uptake
Journal of Physical Fitness and Sports Medicine, 2019 We measured and compared the diet-induced increase in resting oxygen uptake (DIIROU) after moderate-intensity exercise (MIE) with the DIIROU after high-intensity intermittent exercise (HIIE). Eight healthy adult males participated in six testing sessions,

Tailoring Materials for Mottronics: Excess Oxygen Doping of a Prototypical Mott Insulator [PDF]
Advanced Materials 30, 1706708 (2018), 2018 The Mott transistor is a paradigm for a new class of electronic devices---often referred to by the term Mottronics---, which are based on charge correlations between the electrons. Since correlation-induced insulating phases of most oxide compounds are usually very robust, new methods have to be developed to push such materials right to the boundary to
