A Model for Physical Nucleon [PDF]

Progress of Theoretical Physics, 1962
The anomalous magnetic moment of nucleon is investigated by taking the possible ex­ citations of the nucleon core or the cloud pions into account. For the sake of definiteness and simplicity two assumptions are made: 1) the physical nucleon is composed of the static core accompanied by one or no cloud particle, 2) the virtual excitations can be treated

Physical mechanisms relevant to flow resistance in textured microchannels [PDF]

, 2017
Flow resistance of liquids flowing through microchannels can be reduced by replacing flat, no-slip boundaries with boundaries adjacent to longitudinal grooves containing an inert gas, resulting in apparent slip.

Influence of Bubble Shape on Mass Transfer in Multiphase Media: CFD Analysis of Concentration Gradients

Fluids
Our study investigates how non-spherical bubble shapes influence gas–liquid mass transfer across the bubble interface. An analytical shape descriptor, namely Superformula, is used to parametrically define the bubble interface, enabling efficient CFD ...

Enhancing the robustness of a multiplex network leads to multiple discontinuous percolation transitions [PDF]

, 2019
Determining design principles that boost the robustness of interdependent networks is a fundamental question of engineering, economics, and biology. It is known that maximizing the degree correlation between replicas of the same node leads to optimal ...

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...
