Induction Temperature and Feeding Profile Shape the Partitioning Between Soluble Product and Inclusion Body Formation in Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Inclusion body (IB) processes yielding the recombinant product only as IBs are long‐established in the biopharmaceutical industry. Yet, for recombinant proteins that accumulate both IBs and soluble fraction depending on the selected upstream processing (USP) strategy, the influence of process parameters on the partitioning between both forms ...

Doppler effect tailoring: extra-red shift of structured light

open access: yesNature Communications
Doppler effect is a universal phenomenon that describes the frequency shift of waves when interacting with moving targets. Recent studies suggest that the spatial structures of light beams would provide a modification of the group and phase velocities of

Joint detection and tracking using multi-static Doppler-shift measurements

open access: yes, 2012
The problem is to establish the presence and subsequently to track a target using multi-static Doppler shift measurements. The assumption is that in the surveillance volume of interest a single transmitter of known frequency is active with multiple ...

Tensions of Sustainability Logics: Performance of a Company Utilizing a Sustainable Business Model

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT In recent years, companies have used sustainable business models to gain a competitive advantage. However, there are tensions due to the inconsistency between social, environmental, and economic logic in sustainable business models, making it difficult for companies to change. To understand the existing tensions and interactions between logics,

On Doppler-Shift Attenuation Measurements

open access: yes, 1972
An improved analysis of Doppler-shifted γ spectra is outlined. This analysis is exact within the Lindhard theory of slowing down of heavy ions in solids.With an approximate cross section applicable at low energies, the equations become independent of ...

Comparison Between the Acurate Neo and the Acurate Neo 2 Transcatheter Heart Valve System: Impact of Midframe Under‐Expansion

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) with the Acurate Neo has been linked to a significant incidence of paravalvular leakage (PVL), addressed by the Acurate Neo 2 incorporating an active sealing skirt. Recent findings suggest that midframe under‐expansion is associated with worse outcomes.

Metasurface Doppler Cloak for Broadband Radar Stealth

open access: yesAdvanced Physics Research
Concealing an aircraft is a multi‐faceted endeavor, notably involving radio and infrared frequencies. In a radar stealth context, it often translates to the reduction of the radar cross‐section (RCS).

The Doppler Spectra of Medium Grazing Angle Sea Clutter; Part 1: Characterisation [PDF]

open access: yes, 2016
This paper is concerned with the characterisation of Doppler spectra from high range resolution X-band radar sea clutter observed from an airborne platform over the range of grazing angles, 15° to 45°.

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Analysis of the Impact of Doppler Frequency Shift on Phase Noise in Space-Borne Gravitational Wave Detection

open access: yesTechnologies
Space gravitational wave detection is performed via a laser interferometry system across hundreds of thousands to millions of kilometers for picometer-level displacement measurement, using phasemeters to read gravitational wave-induced displacement ...
