Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Measuring bearing currents

open access: yes, 2005
This thesis deals with bearing current detection. It focuses on electric motors driven by variable speed converters. Established techniques for bearing current detection were studied and modified to suit the investigated detecting requirement.

Common-Mode Choke Design to Eliminate Electrostatic Discharge Machining Bearing Currents in Wide-Bandgap Inverter-Fed Motor Drives

open access: yesEnergies
The electrification of mobility sectors, including automotive, aerospace, and robotics, has accelerated the need for compact and high-efficiency power converters in electric motor drives. Wide-bandgap (WBG) semiconductor–based inverters offer significant

Improved design and analysis of a radial magnetic bearing with paired‐pole or alternating‐pole configurations

open access: yesIET Electric Power Applications, 2022
The magnetic saturation of iron‐core will reduce the maximum output force, influence the linear force characteristic and control precision of the magnetic bearing.

The analysis of bearing damage caused bearing currents [PDF]

open access: yes, 2010
The negative influence of bearing currents on the durability of rolling bearings in the alternating current electric motors are shown. The reasons of bearing current formation in electric motors are given. Examples of bearing races damages of cooperating

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Influence of static rotor unbalance on inverter-induced bearing currents

open access: yes, 2022
The influence of static rotor imbalance on the generation of bearing fluting due to bearing currents is experimentally investigated. For that six inverter-fed induction machines with the rated power of 1.5 kW and three with the rated power of 11 kW were ...

A numerical investigation of high-Reynolds-number constant-volume non-Boussinesq density currents in deep ambient [PDF]

open access: yes, 2011
The time-dependent behaviour of non-Boussinesq high-Reynolds-number density currents, released from a lock of height h0 and length x0 into a deep ambient and spreading over horizontal flat boundaries, is considered.
