AB  - The study of graphene thermal conductivity is of great importance, as its anomalous thermal and electrical conductivities (the largest among the all known materials so far) provide very good perspectives for graphene-based nanoelectronics devices. Thermal conductivity of graphene is phonon-based, since its electronic-based thermal conductivity represents less than 1% of the total thermal conductivity at room temperature. For the consideration of the thermal conductivity of graphene the Boltzmann equation in the approximation of relaxation time is used. The relaxation time is determined, with three mechanisms of phonon scattering accounted simultaneously: at defects, at borders, and on phonons. Temperature dependence of thermal conductivity is determined numerically in the range from 15 K to 400 K. The results obtained are in accordance with some other available results found in literature, obtained either experimentally or by numerical calculations.

AB  - In the context of the macroscopic quantum phenomena of the second kind, we hereby seek for a solution-in-principle of the long standing problem of the polymer folding, which was considered by Levinthal as (semi) classically intractable. To illuminate it, we applied quantum-chemical and quantum decoherence approaches to conformational transitions. Our analyses imply the existence of novel macroscopic quantum biomolecular phenomena, with biomolecular chain folding in an open environment considered as a subtle interplay between energy and conformation eigenstates of this biomolecule, governed by quantum-chemical and quantum decoherence laws. On the other hand, within an open biological cell, a system of all identical (noninteracting and dynamically noncoupled) biomolecular proteins might be considered as corresponding spatial quantum ensemble of these identical biomolecular processors, providing spatially distributed quantum solution to a single corresponding biomolecular chain folding, whose density of conformational states might be represented as Hopfield-like quantum-holographic associative neural network too (providing an equivalent global quantum-informational alternative to standard molecular-biology local biochemical approach in biomolecules and cells and higher hierarchical levels of organism, as well).

AB  - We have transformed the Scott's model of protein Hamiltonian to metastable form, by means of double coherent unitary transformation. It turned out that in metastable Hamiltonian the number of quasi particles is not conserved due to the forming of pairs of excitations. The energies of pairs are found and their population is quoted. It is interesting that elementary excitations of metastable state behave similarly as excitations of molecular vibration field as well as excitations of electromagnetic field.

AB  - In this paper we have analyzed phonon thermal conductivity of thin crystalline films, i.e. of low-dimensional structures with dimensional parameters significantly decreased in only one direction. Finding of coefficient of thermal conductivity is achieved by deriving phonon coefficient of diffusion, phonon specific heat and specific density for explored structure. Coefficient of diffusion is derived by applying method of Green functions, using Kubo formula. Then reduced thermal conductivities for film and bulk structures were compared for wider temperature interval. In the last section an influence of changes of heat conductivity on the boundaries is analyzed.

For this type of crystal lattice dispersion relations are well known. Thermodynamic functions (specific heat and phonon thermal conductivity) are calculated via phonon density of states given in exact form. Thermodynamic variables are calculated for a whole temperature range. In limiting cases of low and high temperatures these thermodynamic variables can be found in analytic forms. For thermal conductivity the results of Callaway model for exact phonon density of states are compared with the results of Callaway model for Debye approximation of phonon density of states.

AB  - In the nanocylinder, a cut-off from the molecular crystal, dielectric permeability tensor is investigated. Excitons in the nanocylinder arise due to the exciting of the electron subsystem of the molecule. In evaluation of dielectric permeability Dzhyaloshinskii-Pitaevskii approach is used, connected with retarded and advanced exciton Green's functions and correct use of Paulion Green's function. It turned out that refraction and absorption indices depend on configuration coordinates, having maximal values at boundary cross-sections and minimal value at central cross-section of the nanocylinder broken symmetry structure. Although it was expected that boundary conditions make higher refractive and absorptive characteristics of the nanocylinder, this appeared not to be possible because Paulion Green's function is not proportional to the exciton concentration.

AB  - Two unresolved issues of the (semi)classically addressed problems in molecular biophysics are unreasonably long time necessary for the change of biopolymer conformations and long-range directedness of selective biomolecular recognition processes - implying their essential quantum origin. In this paper several possible quantum approaches to biomolecular recognition are considered: Theory of Non-Radiative Resonant Structural Transitions, Model of Quantum Decoherence, and Resonant Recognition Model. These approaches might be of fundamental importance in understanding underlying macroscopic quantum-holographic Hopfield-like control mechanisms of morphogenesis, and their backward influence on the expression of genes, with significant potential psychosomatic implications.
AB  - Dva nerazrešena pitanja semi-klasično postavljnih problema u molekularnoj biofizici jesu nerazumno dugo vreme potrebno za izmenu biomolekularnih konformacija i dugo-dometna usmerenost selektivnih procesa biomolekularnog prepoznavanja. U radu je razmotreno nekoliko mogućih kvantnih prilaza rešavanju ovih problema. Predloženi kvalitativni scenario je dovoljno opšti i čini dobru osnovu za principijelno rešenje problema biopolimernog sklupčavanja u nativnu konformaciju pri visoko selektivnim procesima protein/receptor biomolekularnog prepoznavanja, implicirajući makroskopsku kvantnu nelokalnost na biološkom ćelijskom nivou. (Bazična nelokalnost se može proširiti i na makroskopski kvantni nivo biološkog organizma na šta ukazuje makroskopska kvantna mikrotalasna rezonantna terapija akupunkturnog sistema.) Kvantna priroda ovih procesa ilustrovana je na primeru neradijativnih strukturnih prelaza, modelu kvantne dekoherencije i modelu rezonantnog prepoznavanja uz diskusiju implementirajućeg mehanizma elektronsko-konformacione sprege u ključ-brava uklapajućim konformacionim prelazima biomolekularnog prepoznavanja protein/supstrat. Na osnovu ovih prilaza u stanju smo da reprodukujemo kako egzistenciju i stabilnost (stacionarnih) polimernih konformacija tako i kratka vremena za kvantno -mehaničke procese u konformacionim prelazima u selektivnim procesima biomolekularnog prepoznavanja. Pošto ovi procesi dovode do dinamičke modifikacije više-elektronske hiperpovrši energija-stanje ćelijskog protein/receptor ansambalskog biomolekularnog makroskopskog kvantnog sistema, to otvara mogućnost razmatranja ćelijskog biomolekularnog prepoznavanja kao Hopfildove kvantno-holografske asocijativne neuronske mreže. Ovi prilazi mogu biti od fundamentalnog značaja za razumevanje bazičnih makroskopskih kvantno-holografskih Hopfildovih kontrolnih mehanizama morfogeneze i njihovog povratnog uticaja na ekspresiju genoma.

Kvantna priroda ovih procesa ilustrovana je na primeru neradijativnih strukturnih prelaza, modelu kvantne dekoherencije i modelu rezonantnog prepoznavanja uz diskusiju implementirajućeg mehanizma elektronsko-konformacione sprege u ključ-brava uklapajućim konformacionim prelazima biomolekularnog prepoznavanja protein/supstrat. Na osnovu ovih prilaza u stanju smo da reprodukujemo kako egzistenciju i stabilnost (stacionarnih) polimernih konformacija tako i kratka vremena za kvantno -mehaničke procese u konformacionim prelazima u selektivnim procesima biomolekularnog prepoznavanja. Pošto ovi procesi dovode do dinamičke modifikacije više-elektronske hiperpovrši energija-stanje ćelijskog protein/receptor ansambalskog biomolekularnog makroskopskog kvantnog sistema, to otvara mogućnost razmatranja ćelijskog biomolekularnog prepoznavanja kao Hopfildove kvantno-holografske asocijativne neuronske mreže. Ovi prilazi mogu biti od fundamentalnog značaja za razumevanje bazičnih makroskopskih kvantno-holografskih Hopfildovih kontrolnih mehanizama morfogeneze i njihovog povratnog uticaja na ekspresiju genoma.",
