switching costs

, 2008
Switching costs arise when transactions, learning, or pecuniary costs are incurred by a user who changes suppliers (including for ‘follow-on’ or ‘aftermarket’ products such as refills and repairs). The ex post market power that switching costs give suppliers need not create inefficiencies, and early ‘bargain’ prices can compensate consumers for later ...

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

FEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Possibility to increase the speeds of express and high-speed trains by turnouts and connecting tracks

Вестник Научно-исследовательского института железнодорожного транспорта, 2016
The possibility of increasing motion speeds of express (“Lastochka”) and high-speed (“Sapsan”) electric trains by the side direction of express (project 2726) and high-speed railway (project 2956) switches is experimentally investigated.

Tunable THz and Infrared Plasmonic Filters and Switches Based on Circular Graphene Resonator With 90$^\circ$ Bending of Output Port

IEEE Photonics Journal, 2020
Two types of novel graphene-based components, namely, filters and electro-optical switches in guided wave configuration are suggested and analysed. The filters differ from the known ones with collinear orientation of the input and output waveguides by ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
