Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, EarlyView.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Towards a background independent approach to M theory [PDF]

, 1998
Work in progress is described which aims to construct a background independent formulation of M theory by extending results about background independent states and observables from quantum general relativity and supergravity to string theory.

OPTIMAL SERVICE TERM OF THE BRIDGE CRANES

Journal of KONES. Powertrain and Transport, 2015
The questions of the rational/optimal service term of the warehouse bridge cranes on the exploitation and projection stages are observed. The method of the residual crane resource’s definition by the criterion of the specific reduced responses is suggested.

An inclined tower crane suited to bridge tower construction

Scientific Reports, 2022
AbstractA new type of tower crane which could transform its tower body is presented. The inclined tower crane body can be tilted at some angle, which suits the construction of buildings with inclined architectural outlines, especially for the construction of bridge towers.

Failure analysis of a bridge crane shaft

Case Studies in Engineering Failure Analysis, 2014
AbstractFailure analysis of a shaft used in a bridge crane has been carried out. The shaft fractured in the keyway with evidence of fatigue. Chemical analysis, micro-structural characterization, fractography, hardness measurements, and finite element simulation were used for the analysis.

Human Capital Robotic Integration and Value Creation for Organizations

Journal of Organizational Behavior, EarlyView.
ABSTRACT Due to rapid advancements in artificial intelligence and machine learning, the research conversation has drifted from viewing robots as replacements for humans (i.e., the substitute view) to a view that considers the possible benefits of human–robot collaboration in the workplace (i.e., the complementary view).
