Transition state

The partitioned survival model (PSM) and the state transition model (STM) are widely used in costeffectiveness analyses of anticancer drugs. Using different modeling approaches with or without consideration of brain metastasis, we compared the quality-adjusted life-year (QALY) estimates of Osimertinib and pemetrexedplatinum in advanced non-small cell lung cancer with epidermal growth factor receptor mutations.

The derived temperature dependences of the peak intensities, separations and half-widths of the separate spectral peaks in the A-band phonon progressions indicate the different trends for vibration-free zero-phonon electronic transition and vibration-related lower-energy electronic transitions to high vibrational levels of the ground electronic state – lower thermal damping and more softened phonon for the zero-phonon transition, also implying the extended defect origin of the A-band photoluminescence.

This article presents computational insights into the geometric and electronic structures of NbSi4 −/0 clusters using density functional theory and the CASSCF/CASPT2 method. The anionic and neutral ground states are identified as the 1A′ and 2A′ states, respectively, within a trigonal bipyramidal isomer where the Nb atom occupies the equatorial position. The adiabatic detachment energy for the transition from the anionic ground state 1A′ to the neutral ground state 2A′ is estimated to be 2.30 eV.

Ebook "Cell polarity 2: Role in development and disease" provides a state-of-the art overview on the most relevant aspects of cell polarity. Volume 2 discusses the physiological and pathophysiological relevance of cell polarity. It especially focuses on pathophysiological conditions in which one or several aspects of cell polarity are impaired, and in which a loss of cell polarity possibly contributes to disease (e.g. epithelial-to-mesenchymal transition in cancer, role of polarity proteins in cancer).

Ebook "Electron correlation in metals" discusses the following issues: enhancements of electronic specific heat and magnetic susceptibility, effects of electron correlation on transport phenomena such as electric resistivity and Hall coefficient, magnetism, Mott transition and unconventional superconductivity. These originate commonly from the Coulomb repulsion between electrons. In particular, superconductivity in strongly correlated electron systems is discussed with a unified point of view.

Ebook "Far-field optical nanoscopy (Springer series on Fluorescence: Methods and applications, Volume 14)" discusses the initial and more recent concepts that can provide far-field optical resolution down to the molecular scale. It is shown that all concepts reported to date exploit a transition between a bright and a dark state to switch fluorescence such that adjacent objects or molecules emit sequentially in time. Some of these concepts can be extended to signal-giving mechanisms other than fluorescence.

Ebook "Iron catalysis II (Topics in Organometallic chemistry, Volume 50)" outlines new avenues for the production of a variety of organic compounds under iron catalysis. Challenges still remain. Iron complexes exhibit a number of features that are not prevalent for other transition metals. Iron is stable in a variety of oxidation states, with +2 and +3 being probably the most prevalent ones for precatalysts.

Ebook "The non-ergodic nature of internal conversion: An experimental and theoretical approach" investigates the transitions from one electronically excited state to another. Such processes - the fastest of events in chemistry - can be studied with femtosecond resolution, and Thomas S. Kuhlman approaches the question both with experimental and theoretical methods. His approach contributes to explain processes of high importance to all scientific fields concerned with the interaction between light and matter: the deactivation of the electronically excited states after excitation.
