The compute-and-forward (CoF) is a relaying protocol, which uses algebraic structured codes to harness the interference and remove the noise in wireless networks. We propose the use of phase precoders at the transmitters of a network, where relays apply CoF strategy. Firstly, we define the phase precoded computation rate and show that it is greater than the original computation rate of CoF prot...

Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (...

Crystal-orientation fabric (COF) has a large influence on ice-sheet flow. Earlier radar studies have shown that COF-based birefringence occurs within ice sheets. Radio-wave scattering in polar ice results from changing physical properties of permittivity and conductivity that arise from differing values of density, acidity and COF. We present an improved mathematical model that can handle all t...

Crystallinity and porosity are of central importance for many properties of covalent organic frameworks (COFs), including adsorption, diffusion, and electronic transport. We have developed a new method for strongly enhancing both aspects through the introduction of a modulating agent in the synthesis. This modulator competes with one of the building blocks during the solvothermal COF growth, re...

We demonstrate photocatalytic hydrogen evolution using COF photosensitizers with molecular proton reduction catalysts for the first time. With azine-linked N2-COF photosensitizer, chloro(pyridine)cobaloxime co-catalyst, and TEOA donor, H2 evolution rate of 782 μmol h-1 g-1 and TON of 54.4 has been obtained in a water/acetonitrile mixture. PXRD, solid-state spectroscopy, EM analysis, and quantum...

C-cross topologies are introduced. Modifications of the Kuratowski-Ulam Theorem are considered. Cardinal invariants add , cof, cov and non with respect to meager or nowhere dense subsets are compared. Remarks on invariants cof(nwdY ) are mentioned for dense subspaces Y ⊆ X.

We construct a model in which for all 1 ≤ n < ω, there is no stationary subset of אn+1 ∩ cof(אn) which carries a partial square. Let κ be an uncountable cardinal and let μ ≤ κ be regular. A set A ⊆ κ∩cof(μ) is said to carry a partial square if there exists a sequence ⟨cα : α ∈ A⟩ such that each cα is club in α with order type μ, and for all γ which is a common limit point of cα and cβ , cα ∩ γ ...

Context: Mesenchymal odontogenic tumors arise from the remnants of the mesenchymal portion of tooth germ. Central odontogenic fibroma (COF), odontogenic myxoma (OM) and Ameloblastic fibroma (AF) are closely related and show varied clinical presentation and overlapping histopathology. They are differentiated by their collagen quantity, maturity and distribution. Diagnostic difficulties are posed...
