Is external control important for internal control?
Journal of Sociocybernetics, 2016 In cybernetics, the basic assumption is that systems aim for control.But what and how are they controlling? I dierentiate two categories ofcontrol: internal and external control. In external control, one starts fromoutside, and tries to determine the environment completely. While withinternal control, one's own aspirations are taken as a starting point,

FEBS Open Bio, EarlyView.In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Internal control of the Schrödinger equation
Mathematical Control & Related Fields, 2014 In this paper, we intend to present some already known results about the internal controllability of the linear and nonlinear Schr dinger equation. After presenting the basic properties of the equation, we give a self contained proof of the controllability in dimension 1 using some propagation results.

Helicopter internal noise control: Three case histories [PDF]
Case histories are described in which measurable improvements in the cabin noise environments of the Bell 214B, 206B, and 222 were realized. These case histories trace the noise control efforts followed in each vehicle.

FEBS Open Bio, EarlyView.d‐Allulose can be produced from d‐fructose by d‐allulose 3‐epimerase. Based on sequence homology information, we successfully engineered thermostable mutants with the protein engineering method. By integrating positive mutations, we constructed an enzyme that exhibits hyperthermostability without a loss in the activity.
