β-Ti Alloys for Orthopedic and Dental Applications
Ti and Ti alloys have charming comprehensive properties (high specific strength, strong corrosion resistance, and excellent biocompatibility) that make them the ideal choice in orthopedic and dental applications, especially in the particular fabrication of orthopedic and dental implants. However, these alloys present some shortcomings, specifically elastic modulus, wear, corrosion, and biological performance. Beta-titanium (β-Ti) alloys have been studied as low elastic modulus and low toxic or non-toxic elements.

Yoga Using Intelligent Internet of Things
The detection and monitoring of the yoga postures are possible with the Intelligent Internet of Things (IIoT), which is the integration of intelligent approaches (machine learning) and the Internet of Things (IoT). Considering the increment in yoga practitioners, the integration of IIoT and yoga has led to the successful implementation of IIoT-based yoga training systems.

Yoga Pose Estimation
Correct posture alignment is crucial in the practice of yoga. Posture is essential for all forms of exercise, but it is particularly critical in yoga to obtain the benefits and prevent yoga-related sports injuries. Yoga pose classification has been accomplished using a variety of computer vision techniques.

Yield
In chemistry, yield, also referred to as reaction yield, is a measure of the quantity of moles of a product formed in relation to the reactant consumed, obtained in a chemical reaction, usually expressed as a percentage. Yield is one of the primary factors that scientists must consider in organic and inorganic chemical synthesis processes. In chemical reaction engineering, "yield", "conversion" and "selectivity" are terms used to describe ratios of how much of a reactant was consumed (conversion), how much desired product was formed (yield) in relation to the undesired product (selectivity), represented as X, Y, and S.

Wheelchair Skills Training Using Virtual Reality
It is estimated that 1% of the global population are wheelchair users (WUs). To promote the integration of WUs in society and enhance their independence, it is important that they know how to manoeuvre a wheelchair safely. Several training programmes for wheelchair driving skills have been developed; some programmes entail navigating in everyday settings (i.e., homes, schools, etc.), while others focus on controlled environments where a set of tasks are performed.

Wet Nanotechnology
Wet nanotechnology (also known as wet nanotech) involves working up to large masses from small ones. Wet nanotechnology requires water in which the process occurs. The process also involves chemists and biologists trying to reach larger scales by putting together individual molecules. While Eric Drexler put forth the idea of nano-assemblers working dry, wet nanotech appears to be the likely first area in which something like a nano-assembler may achieve economic results. Pharmaceuticals and bioscience are central features of most nanotech start-ups. Richard A.L. Jones calls nanotechnology that steals bits of natural nanotechnology and puts them in a synthetic structure biokleptic nanotechnology. He calls building with synthetic materials according to nature's design principles biomimetic nanotechnology. Using these guiding principles could lead to trillions of nanotech robots, that resemble bacteria in structural properties, entering a person's blood stream to do medical treatments.

Wearable Technology for Monitoring Electrocardiograms in Adults
In the rapidly evolving landscape of continuous electrocardiogram (ECG) monitoring systems, there is a heightened demand for non-invasive sensors capable of measuring ECGs and detecting heart rate variability (HRV) in diverse populations, ranging from cardiovascular patients to sports enthusiasts. Challenges like device accuracy, patient privacy, signal noise, and long-term safety impede the use of wearable devices in clinical practice.

Wearable Sensors in Sports
Wearable sensor technology provides an alternative to classical laboratory-based assessments of human performance that enables real-time monitoring in natural environments, without the cumbersome set-up procedure and limitations related to space. We conducted a scoping review, aiming to present an overview of existing methods for assessments of shock impacts using wearable sensor technology within two domains: sports and occupational settings.

Wearable Sensors and Machine Learning for Hypovolemia Problems
Hypovolemia is a physiological state of reduced blood volume that can exist as either (1) absolute hypovolemia because of a lower circulating blood (plasma) volume for a given vascular space (dehydration, hemorrhage) or (2) relative hypovolemia resulting from an expanded vascular space (vasodilation) for a given circulating blood volume (e.g., heat stress, hypoxia, sepsis). The external environment and the user's level of physical activity can exacerbate hypovolemic challenges to the body. Noninvasive, wearable sensing systems are being developed to track a user's ability to compensate for these challenges.
