Globins (Glbs) are proteins widely distributed in organisms. Three evolutionary families have been identified in Glbs: the M, S and T Glb families. The M Glbs include flavohemoglobins (fHbs) and single-domain Glbs (SDgbs); the S Glbs include globin-coupled sensors (GCSs), protoglobins and sensor single domain globins, and the T Glbs include truncated Glbs (tHbs). Structurally, the M and S Glbs ...

I review the field of globular cluster system (GCS) kinematics, including a brief primer on observational methods. The kinematical structures of spiral galaxy GCSs so far appear to be broadly similar. The inferred rotation and mass profiles of elliptical galaxy halos exhibit a diversity of behaviors, requiring more systematic observational and theoretical studies.

We present a study of the colors of globular clusters associated with the elliptical galaxy NGC 3923. Our nal sample consists of Washington system C and T1 photometry for 143 globular cluster candidates with an expected contamination of no more than 10%. We nd that the color distribution of the NGC 3923 globular cluster system (GCS) is broad and appears to have at least two peaks. A mixture mod...

The generalized conditional symmetry (GCS) method is applied to a specific case of the Klein–Gordon–Fock (KGF) equation with central symmetry. We first investigate the conditions which yield the KGF equation that admits special class of secondorder GCSs. The determining system for the unknown functions is solved in several special cases. New symmetry operators and related exact solutions, diffe...

The major task in quantum control theory is to find an external field that transforms the system from one state to another or executes a predetermined unitary transformation. We investigate the difficulty of computing the control field as the size of the Hilbert space is increased. In the models studied the controls form a small closed subalgebra of operators. Complete controllability is obtain...

Unmanned Aerial Vehicles (UAVs) are being extensively used nowadays. Therefore, pilots of traditional aerial platforms should adapt their skills to operate them from a Ground Control Station (GCS). Common GCSs provide information in separate screens: one presents the video stream while the other displays information about the mission plan and information coming from other sensors. To avoid the ...

We present a new method by which the total masses of galaxies including dark matter can be estimated from kinematics their globular cluster systems (GCSs). In proposed method, we apply convolutional neural networks (CNNs) to two-dimensional (2D) maps line-of-sight-velocities ($V$) and velocity dispersions ($\sigma$) GCSs predicted numerical simulations disk elliptical galaxies. this first train...

This paper contributes to the design of Groupware Calendar Systems (GCSs) for use in domestic life. We consider a number of ethnographic studies of calendar use in domestic circumstances to illuminate the design space and inform design reasoning. GCSs have been employed in the workplace for sometime and have been informed by studies of ‘calendar work’. As design moves out of the workplace and i...

We studied the relation between the ratio of rotational velocity to velocity dispersion and the metallicity (< vrot > /σv-metallicity relation) of globular cluster systems (GCS) of disk galaxies by comparing the relation predicted from simple chemo-dynamical models for the formation and evolution of disk galaxies with the observed kinematical and chemical properties of their GCSs. We conclude t...

We investigate the structural, kinematical, and chemical properties of globular cluster systems (GCSs) in galaxies of different Hubble types in a self-consistent manner based on high-resolution cosmological N-body simulations combined with semianalytic models of galaxy and globular cluster (GC) formation. We focus on correlations between the physical properties of GCSs and those of their host g...
