A patent application by Nvision Imaging Technologies GmbH for the invention of systems and methods to generate hyperpolarized materials has been made available online. The technology aims to increase nuclear spin polarization beyond thermal equilibrium values to enhance sensitivity in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) applications. By transferring polarization from a polarized source compound to a target compound, this innovation can lead to new applications in medical imaging, in vivo metabolism imaging, and molecular dynamics visualization. The patent application outlines detailed methods and systems for achieving increased nuclear spin polarization in target compounds, potentially revolutionizing NMR and MRI signal sensitivity.

A recent study conducted by Stellenbosch University in Cape Town, South Africa, explored the influence of childhood trauma and traumatic stress on a woman's risk of having a child with a fetal alcohol spectrum disorder (FASD). The research found that maternal childhood trauma scores were associated with a slightly increased likelihood of having a child diagnosed with FASD. However, the study did not demonstrate a direct influence of maternal childhood trauma on FASD diagnosis. The findings suggest that maternal trauma may indirectly contribute to the risk of having a child with FASD. [Extracted from the article]

A patent application titled "Systems And Methods For Generation Of Hyperpolarized Materials" has been published online by Nvision Imaging Technologies GmbH. The patent application describes a method and system for increasing the nuclear spin polarization of a target compound using the intermolecular nuclear Overhauser effect. This increased polarization can improve the sensitivity of nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) applications. The method involves imparting a non-thermal equilibrium nuclear spin polarization to a source compound and transferring this polarization to the target compound. The patent application provides detailed descriptions of the method and system, as well as various embodiments and applications. [Extracted from the article]

The method of claim 15, further comprising performing, when the quality metric is less than a threshold, one or more of: prompting the user to reposition the hearing device, discarding the optical measurement performed by the optical measurement device, abstaining from taking the optical measurement to be performed by the optical measurement device, and disabling the optical measurement device." For example, the output signal emitted inside the ear canal by the emitting device may be attenuated or blocked by the hearing device seated in the ear canal so that the sensor outside the ear canal may detect a strongly attenuated output signal or no output signal at all. The system of claim 2, wherein the emitting device is provided by an output transducer of the hearing device and wherein the sensor is provided by a microphone of the hearing device.

"In an exemplary embodiment, the system further comprises a toothbrush, wherein the toothbrush and the devices are configured to interconnect by a wireless data connection as soon as the system is in tooth brushing monitoring mode. The system of claim 3, further configured to detect and analyze acceleration differences in the data of the first accelerometer and the second accelerometer for at least one of the devices to differentiate chewing from other types of movement. "In an exemplary embodiment, the system is further configured to detect and analyze acceleration differences in the data of the first accelerometer and the second accelerometer for at least one of the devices to differentiate chewing from other types of movement. "In an exemplary embodiment, an orientation of the first accelerometer and the second accelerometer is detected in two opposite phases of the periodic movement, wherein the periodic movement is identified as not chewing if the orientation of the first accelerometer relative to the second accelerometer remains the same within a predetermined range in both phases.
