A series of pyrimidine-embedded polyheterocycles was synthesized using a pDOS strategy in a facile manner. The resulting poly-heterocyclic core skeletons containing a unique aza-tricyclic framework allowed for diverse display of non-covalent interacting elements, which probably serve as essentials for perturbing specific non-covalent interactions between various biopolymers.

Pristine graphene and derivatives have been investigated with the density functional theory (DFT). The calculations consist of structural optimization, states (DOS), projected (PDOS) based on orthorhombic 4-atom unit cell. obtained results are in good agreement experimental data. highest deviations from experiment 0.35 % 0.28 for lattice constant bond length, respectively. In addition, DOS, PDO...

Once the EU has perceived strategic importance of local peculiarities to support rural development and high-quality productions, it emphasized need for more place-sensitive agri-food policies. The socio-economic, historical cultural factors as transfers intangible value-added is particularly evident in sector. Place-blind sectorial-oriented approaches have indeed not succeeded dealing with terr...

Omnidirectional light propagation in a realistic superlattice is investigated. This work complements two previous articles [Phys. Rev. E 59, 3624 (1999); 61, 5802 (2000)] that analyzed the cases of transverse electric (TE) and transverse magnetic (TM) polarization modes, respectively, of the dielectric superlattice modeled by means of Dirac delta functions. We present a quantitative analysis of...

The protection of geographical indications (European regulation 1151/2012) is arguably the most significant initiative, certainly within Europe, that promotes foods with territorial associations and reorganises agri-food chain governance through a strategy of reterritorialisation. Research on Protected Designation of Origins (PDOs) and Protected Geographical Indications (PGIs) suggests that the...

Influence of disorder, antisite defects, martensite transition and compositional variation on the magnetic properties and electronic structure of Mn(2)NiGa and Mn(1+x)Ni(2-x)Ga magnetic shape memory alloys have been studied by using full potential spin-polarized scalar relativistic Korringa-Kohn-Rostocker (FP-SPRKKR) method. Mn(2)NiGa is ferrimagnetic and its total spin moment increases when di...

OBJECTIVE Patient-derived organoids (PDOs), used in multiple tumor types, have allowed evaluation of tumor characteristics from individual patients. This study aimed to assess the feasibility of applying PDO in vitro culture for endocrine-based and drug sensitivity testing in endometrial cancer. METHODS Endometrial cancer cells were enzymatically dissociated from tumors retrieved from fresh h...

An Unattended Wireless Sensor Network (UWSN) can be used in many applications to collect valuable data. Nevertheless, due to the unattended nature, the sensors could be compromised and the sensor readings would be maliciously altered so that the sink accepts the falsified sensor readings. Unfortunately, few attentions have been given to this authentication problem. Moreover, existing methods su...

Starch is a carbohydrate consisting of a large number of glucose units joined by glycosidic bonds. An ab initio study based on density functional theory implemented in computational program SIESTA is the prime theme of present paper. In which LDA exchange co-relation environment is used to obtain density of states (DOS), projected/partial density of states (PDOS), charge density, electronic ban...

Fungus-resistant grapes (FRGs), or pilzwiderstandfähig (PIWI) in German, are obtained through crossbreeding Vitis vinifera and other species. FRG adoption is among the most promising strategies to pursue improve sustainability wine industry; however, actual spread impact on will largely depend designation certification possibilities procedures for wines, line with framework set by European Unio...
