A combination of atomic correlation statistics and quantum chemical calculations are shown to predict biological function. In the present study, various antigenic peptide-Major Histocompatibility Complex pMHC ligands with near-identical stereochemistries, in complexation with the same T cell receptor TCR , were found to consistently induce distinctly different quantum chemical behavior, directly dependent on the peptide's electron spin density and intrinsically expressed by the protonation state of the peptide's N-terminus. Furthermore, the cumulative coordination difference of any variant in respect to the native peptide was found to accurately reflect peptide biological function and immerges as the physical observable which is directly related to the immunological end-effect of pMHC-TCR interaction.

Designing interfaces in energy materials applications with first-principles calculations

RameshKumar b. RashvandAvei c. The inhibitory effect of Oxethazaine drug, 2,2'- 2-Hydroxyethylimino bis[N- alphaalpha-dimethylphenethyl -N-methylacetamide] on corrosion of mild steel in 1M HCl solution was studied by weight loss measurements, electrochemical impedance spectroscopy and potentiodynamic polarization methods. The results of gravimetric and electrochemical methods demonstrated that the inhibition efficiency increased with an increase in inhibitor concentration in 1M HCl solution. The results from electrochemical impedance spectroscopy proved that the inhibition action of this drug was due to adsorption on the metal surface. Potentiodynamic polarization studies revealed that the molecule was a mixed type inhibitor.

Topological Quantum Materials

Quantum chemistry , also called molecular quantum mechanics , is a branch of chemistry focused on the application of quantum mechanics to chemical systems. Chemists rely heavily on spectroscopy through which information regarding the quantization of energy on a molecular scale can be obtained. Common methods are infra-red IR spectroscopy , nuclear magnetic resonance NMR spectroscopy , and scanning probe microscopy. Quantum chemistry studies the ground state of individual atoms and molecules, and the excited states , and transition states that occur during chemical reactions. On the calculations, quantum chemical studies use also semi-empirical and other methods based on quantum mechanical principles, and deal with time dependent problems. Many quantum chemical studies assume the nuclei are at rest Born—Oppenheimer approximation. Many calculations involve iterative methods that include self-consistent field methods.

Topological superconductors, Majoranas, Weyl materials, Scattering theory of topological insulators, Periodically driven systems, Advanced mathematical formulation of topological invariants; Prerequisites for the intensive week course: The course is recommended for graduate students in the Master program; Good knowledge of basic quantum. For years, electronic band theory has been dominated by important quantitative aspects such as the relative energy of bands in materials composed of chemical elements sitting on lattice sites. Topological materials are intriguing because their surfaces can conduct electricity without resistance, so they are potentially faster and more energy-efficient than today's technologies.

Он постарался выкинуть этот эпизод из головы. Если повезет, он успеет вернуться и все же съездить с Сьюзан в их любимый Стоун-Мэнор. Туда и обратно, - повторил он.  - Туда и обратно. Если бы он тогда знал… ГЛАВА 9 Техник систем безопасности Фил Чатрукьян собирался заглянуть в шифровалку на минуту-другую - только для того, чтобы взять забытые накануне бумаги. Но вышло .

Да, да, прямо. К тому же у нас вышел из строя генератор. Я требую направить сюда всю энергию из внешних источников. Все системы должны заработать через пять минут. Грег Хейл убил одного из младших сотрудников лаборатории систем безопасности и взял в заложники моего старшего криптографа. Если нужно, используйте против всех нас слезоточивый газ. Если мистер Хейл не образумится, снайперы должны быть готовы стрелять на поражение.

We apologize for the inconvenience...

ГЛАВА 68 - Ну видишь, это совсем не трудно, - презрительно сказала Мидж, когда Бринкерхофф с видом побитой собаки протянул ей ключ от кабинета Фонтейна. - Я все сотру перед уходом, - пообещала.  - Если только вы с женой не захотите сохранить этот фильм для своей частной коллекции. - Делай свою распечатку и выметайся! - зарычал. - Si, senor, - засмеявшись, ответила Мидж с подчеркнутым пуэрто-риканским акцентом и, подмигнув Бринкерхоффу, направилась к двойной двери директорского кабинета.

Сзади, перпендикулярно туннелю, начинался коридор, едва освещаемый красными лампочками, вмонтированными в пол. - Пойдемте, - позвал Бринкерхофф, помогая Сьюзан вылезти. Она шла следом за ним точно в тумане.
