Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

FEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Robust Adaptive Tuning of Digitally Controlled Switched-Mode Power Supplies

, 2009
This paper presents an approach to continuous adaptive tuning of digitally controlled switched-mode power supply (SMPS) feedback loops. Tuning is performed via a multiple-input, multiple-output (MIMO) control loop that adjusts compensator parameters such

An Offline Condition Monitoring Method for the DC-Link Capacitors in Power Electronic Converters

IEEE Access
Electrolytic capacitors are widely used as DC-link components in power electronic converters such as switched-mode power supplies (SMPSs) and inverters; however, they are also among the most vulnerable components, and their capacitance degradation ...

Self‐Regulated Learning Meets AI: Reinterpreting Self‐Regulation, Co‐Regulation, and Socially Shared Regulation in Human–AI Interaction

New Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

Ofatumumab in Myelin Oligodendrocyte Glycoprotein Antibody–Associated Disease: A Comparison With Rituximab

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the efficacy and safety of ofatumumab in patients with myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), and compare it with rituximab. Methods We conducted a single–center, observational study including 22 MOGAD patients treated with ofatumumab and 21 treated with rituximab.

Triple buck converter – an efficient low-distortion switch-mode power amplifier topology

The Journal of Engineering, 2019
A switch-mode power amplifier topology that can achieve both a high conversion efficiency and low-output signal distortion is introduced. Such systems are desirable for ultra-high precision amplifiers that, for example, drive actuators in nanometre ...

Global Rather Than Vertical‐Selective Saccadic Abnormalities in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To test whether vertical saccades are preferentially affected in Progressive Supranuclear Palsy (PSP). Methods PSP patients (n = 24) were compared to age‐matched controls (n = 94) and two degenerative groups (Alzheimer's disease, n = 20; Lewy body disease, n = 50).

Transformer Isolated Buck-Boost Converters

Renewable Energy and Sustainable Development, 2016
Of the single-switch dc-to-dc converters, those with the buck-boost voltage transfer function offer most potential for transformer coupling, hence isolation, at the kilowatt level. This paper highlights the limitations of the traditional magnetic coupled,
