We have applied a novel theoretical and computational method called CECILIA (combined embedded cluster at the interface with liquid approach) to study adsorption of molecular water on the MgO(001) surface and its interface with water. The MgO(001) surface is modeled by a quantum cluster embedded in a field of pseudopotentials and point charges. The effects of an aqueous environment are included...
The CP29 light harvesting complex from green plants is a pigment-protein complex believed to collect, conduct, and quench electronic excitation energy in photosynthesis. We have spectroscopically determined the relative angle between electronic transition dipole moments of its chlorophyll excitation energy transfer pairs in their local protein environments without relying on simulations or an X...
qeeg به مفهوم ساده عبارتست از آنالیز کمی (quantitative) امواج یک نوار مغزی برای پی بردن به مختصات کمی موج های موجود در آن از جمله توزیع کمی امواج در محل های مختلف جمجمه یا قدرت هر کدام از امواج از نظر دامنه. در این مطالعه به منظور درک بهتر اختلال اسکیزوافکتیو ، تعداد 40 بیمار بطور تصادفی و بر اساس معیارهای ورود و خروج از مطالعه انتخاب شدند و نوار مغزی آنها که به شیوه کمی مورد آنالیز قرار گرفت...
Coherence oscillations measured in two-dimensional (2D) electronic spectra of pigment-protein complexes may have electronic, vibrational, or mixed-character vibronic origins, which depend on the degree of electronic-vibrational mixing. Oscillations from intrapigment vibrations can obscure the inter-site coherence lifetime of interest in elucidating the mechanisms of energy transfer in photosynt...
Structures and spectra are calculated for Si(n) and Si(n)-Gly (n = 3-5) complexes. Relative stability differences of Gly conformers are magnified by interactions with the Si(n) cluster, so that one conformer of Si(n)-Gly is stabilized. Significant charge transfer occurs from the amino group in Gly to a Si atom in the cluster. Interactions with Gly are predicted to shift the excitation energies ...
The interaction of carbonic anhydrase (CA) isozymes I and II with a series of As(III) derivatives, dialkyl and diaryl rac-2,3-dimyristoyloxypropyldithioarsonites, was investigated kinetically and spectrophotometrically, utilizing the native and Co(II)-substituted enzymes. Depending on the substitution pattern at the -As(SR)(2) moiety of the investigated derivatives, inactive compounds were foun...
The single- and many-particle Coulomb excitation spectra in Bernal bilayer graphene can be modulated by a uniform perpendicular electric field. The field-induced oscillatory parabolic bands possess saddle points and local extrema, which, respectively, lead to logarithmically divergent peaks and discontinuous steps in the bare response functions. Such special structures are associated with the p...
We propose the idea of single cell dielectric spectroscopy for future clinical applications such as cell therapy and regenerative medicine. The structure of the microfluidic device is carefully designed to suppress the influence of electrode polarization on the dielectric spectra of single cells. Beads of uniform size distribution is used to determine the detection limit. As feasibility tests f...
