Effects of Mechanical Vibrations on Stress Distribution and Displacement in Bone and Teeth Surrounding Infrazygomatic Screws: An In-vitro Finite Element Analysis Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Infrazygomatic Crest (IZC) Mini-Implants (MI) is widely used in orthodontics for stable anchorage. However, the impact of mechanical vibrations on bone stress distribution and implant stability remains poorly understood.

An analysis of stress and burnout in UK general dental practitioners: subdimensions and causes [PDF]

British Dental Journal, 2019
Dentistry is well documented as a stressful profession. The majority of UK dentists work in general practice, which can carry multiple sources of stress. Previous research has acknowledged the propensity of these sources of stress for general dental practitioners (GDPs) when undertaking clinical, administrative and managerial tasks.

Memristor‐Driven Active‐Matrix Organic Light‐Emitting Diode for Energy Efficient and High‐Resolution Displays

Advanced Functional Materials, EarlyView.
This study demonstrates that memristors can replace conventional 2T–1C driving circuits with simplified 1T–1 m architectures by exploiting resistance switching. With ultra‐low switching voltages (< ±0.2 V) and multi‐level resistance states, the memristors precisely control the current injected into organic light‐emitting diodes (OLEDs).
