A Unified Mechanism on the Formation of Acenes, Helicenes, and Phenacenes in the Gas Phase. [PDF]
, 2020 A unified low-temperature reaction mechanism on the formation of acenes, phenacenes, and helicenes-polycyclic aromatic hydrocarbons (PAHs) that are distinct via the linear, zigzag, and ortho-condensed arrangements of fused benzene rings-is revealed. This

Quantum Zeno-based control mechanism for molecular fragmentation [PDF]
, 2012 A quantum control mechanism is proposed for molecular fragmentation processes within a scenario grounded on the quantum Zeno effect. In particular, we focus on the van der Waals Ne-Br$_2$ complex, which displays two competing dissociation channels via ...

Gain control in molecular information processing: Lessons from neuroscience [PDF]
, 2011 Statistical properties of environments experienced by biological signaling systems in the real world change, which necessitate adaptive responses to achieve high fidelity information transmission. One form of such adaptive response is gain control.

Mechanisms of two-color laser-induced field-free molecular orientation [PDF]
, 2012 Two mechanisms of two-color (\omega + 2\omega) laser-induced field-free molecular orientation, based on the hyperpolarizability and ionization depletion, are explored and compared. The CO molecule is used as a computational example.

Structural basis of complement membrane attack complex formation [PDF]
, 2015 In response to complement activation, the membrane attack complex (MAC) assembles from fluid-phase proteins to form pores in lipid bilayers. MAC directly lyses pathogens by a ‘multi-hit’ mechanism; however, sublytic MAC pores on host cells activate ...

Dehydration mechanism of a small molecular solid: 5-nitrouracil hydrate [PDF]
, 2013 Previous studies of the dehydration of 5-nitrouracil (5NU) have resulted in it being classified as a ‘‘channel hydrate’’ in which dehydration proceeds principally by the exit of the water molecules along channels in the structure.

Dynamics of an inchworm nano-walker [PDF]
, 2006 An inchworm processive mechanism is proposed to explain the motion of dimeric molecular motors such as kinesin. We present here preliminary results for this mechanism focusing on observables like mean velocity, coupling ratio and efficiency versus ATP ...

Molecular motors: design, mechanism and control
, 2008 Biological functions in each animal cell depend on coordinated operations of a wide variety of molecular motors. Some of the these motors transport cargo to their respective destinations whereas some others are mobile workshops which synthesize ...

, 2008 Molecular codes translate information written in one type of molecules into another molecular language. We introduce a simple model that treats molecular codes as noisy information channels.

The ring-opening polymerization of D,L-lactide in the melt initiated with tetraphenyltin [PDF]
, 1984 Melt polymerization conditions for D,L-lactide initiated with tetraphenyltin were studied with regard to polymer molecular weight and weight distributions.
