Effect of thermal fluctuations on the nontrivial topology of the + superconducting phase.

The behavior of the topological index (TI), characterizing the properties of superconducting phases of quasi-two-dimensional systems with nontrivial topology, is investigated depending on the temperature and system parameters. For this purpose, a method of calculating the TI, based on a self-consistent functional-integral theory, is proposed. The chiral + superconducting phase of a quasi-two-dimensional model with effective attraction between the electrons located at the nearest sites of a triangular lattice is considered.

Thermal fluctuations in superconducting phases with chiral+ iandsymmetry on a triangular lattice.

The behavior of thermal fluctuations of a superconducting order parameter with extendedand chiral+ isymmetry is investigated. The study is carried out on a triangular lattice within the framework of the quasi-two-dimensional single-band model with attraction between electrons at neighboring sites. The method of consistent consideration of the order parameter fluctuations and the charge carrier scattering by fluctuations of coupled electron pairs, based on the theory of functional integration is used.

Effect of atomic disorder on the magnetic phase separation.

The effect of disorder on the magnetic phase separation between the antiferromagnetic and incommensurate helical [Formula: see text] and [Formula: see text] phases is investigated. The study is based on the quasi-two-dimensional single-band Hubbard model in the presence of atomic disorder (the [Formula: see text] Anderson-Hubbard model). A model of binary alloy disorder is considered, in which the disorder is determined by the difference in energy between the host and impurity atomic levels at a fixed impurity concentration.

Clinical outcomes from maximum-safe resection of primary and metastatic brain tumors using awake craniotomy.

Objective: To retrospectively analyze outcomes in patients undergoing awake craniotomies for tumor resection at our institution in terms of extent of resection, functional preservation and length of hospital stay.

Patients And Methods: All cases of adults undergoing awake-craniotomy from September 2012-February 2015 were retrospectively reviewed based on an IRB approved protocol. Information regarding patient age, sex, cancer type, procedure type, location, hospital stay, extent of resection, and postoperative complications was extracted.

Brain-targeted delivery of doxorubicin using glutathione-coated nanoparticles for brain cancers.

Objectives: To prepare and characterize in vitro a novel brain-targeted delivery of doxorubicin using glutathione-coated nanoparticles (NPs) for the treatment of brain cancer.

Methods: Doxorubicin-loaded NPs were prepared by the nanoprecipitation method using PLGA-COOH (dl-lactide-co-glycolide). The NPs were coated with a glutathione-PEG conjugate (PEG-GSH) in order to target delivery to the brain.
