Carbon nanotubes (CNTs) are very promising nanodevices due to their extraordinary electrical, thermal, and optical properties. However, as-grown single-walled CNTs (SWCNTs) contain a mixture of semiconducting and metallic species with great features ...

Dispersion-Corrected Mean-Field Electronic Structure Methods.
Mean-field electronic structure methods like Hartree-Fock, semilocal density functional approximations, or semiempirical molecular orbital (MO) theories do not account for long-range electron correlation (London dispersion interaction).

Justification of mixer parameters for flour components
The need to provide the bakery and confectionery industries with new high-tech equipment that would ensure high-quality preparation of mixtures for the main processes in the production of flour semi-finished products with high-quality mixing of dosing ...

Realizing normal group-velocity dispersion in free space via angular dispersion [PDF]
It has long been thought that normal group-velocity dispersion (GVD) cannot be produced in free space via angular dispersion. Indeed, conventional diffractive or dispersive components such as gratings or prisms produce only anomalous GVD. We identify the conditions that must be fulfilled by the angular dispersion introduced into a plane-wave pulse to ...

Improved estimators for dispersion models with dispersion covariates
In this paper we discuss improved estimators for the regression and the dispersion parameters in an extended class of dispersion models (J{\o}rgensen, 1996).

Frequency-Dependent Schroeder Allpass Filters
Since the introduction of feedforward−feedback comb allpass filters by Schroeder and Logan, its popularity has not diminished due to its computational efficiency and versatile applicability in artificial reverberation, decorrelation, and dispersive

Residence time distribution (RTD) has a very high impact on the performance of a chemical reactor. The development of new reactor and catalyst structures has increased the importance of deep knowledge in theories of RTDs and good experimental practice in

General relationships between consumer dispersal, resource dispersal and metacommunity diversity [PDF]
One of the central questions of metacommunity theory is how dispersal of organisms affects species diversity. Here we show that the diversity-dispersal relationship should not be studied in isolation of other abiotic and biotic flows in the metacommunity.

Solitons in media with mixed, high-order dispersion and cubic nonlinearity [PDF]
Although most soliton research has traditionally considered dominant quadratic dispersion, the recent discovery of pure-quartic solitons has inspired analysis of soliton solutions with large higher orders of dispersion. Here we present analytic expressions for families of bright soliton solutions at arbitrary dispersion orders and practical methods to ...

Spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), has become a key pest for soft fruits and cherries in Europe in less than a decade since the first outbreak in 2007.
