Hyperthermia (HT) has broad potential for disease treatment and health maintenance. Previous studies have shown that far-infrared rays (FIRs) at 8-10 μm can potentially reduce inflammation, oxidative stress, gut microbiota imbalance. However, the effects of FIR HT on energy metabolism require further investigation. To investigate graphene-FIR therapy diet-induced obesity their regulatory mechanisms in disorders. After 8 weeks hyperthermia, mice fed standard chow or a high-fat diet (HFD)...
The temporal shape of a pulse in transcranial magnetic stimulation (TMS) influences which neuron populations are activated preferentially as well the strength and even direction neuromodulation effects. Furthermore, various shapes differ their efficiency, coil heating, sensory perception, clicking sound. However, available TMS repertoire is still very limited to few biphasic, monophasic, polyphasic pulses with sinusoidal or near-rectangular shapes. Monophasic pulses, though found be more...
Transcranial magnetic stimulation (TMS) with monophasic pulses achieves greater changes in neuronal excitability but requires higher energy and generates more coil heating than TMS biphasic pulses, this limits the use of rapid-rate protocols. We sought to design a waveform that retains characteristics significantly reduces heating, thereby enabling pulse rates increased neuromodulation effectiveness.

Multilevel converters have enabled various applications that are not possible with conventional two-level converters. Many of these applications, however, need a high output bandwidth, often approaching the switching rate limit transistors, quality, e.g., to actively stabilize and dampen DC grid or specifically excite certain molecules neural circuits in medical applications. A bandwidth challenges existing modulation methods: carrier-based is fine at low frequencies but experiences...
