Abstract: Example embodiments of a radiation detection system including a detector is described. The detector can include a scintillator, a sensor, and a light source. The radiation detection system can further include a controller programmed to control the light source to expose the scintillator to a light to saturate traps in the scintillator. In some embodiments, the detector can further include a second light source, and the controller is programmed to control the second light source to expose the scintillator to a second light to detrap afterglow traps in the scintillator.

Abstract: Compounds are disclosed that inhibit RhoGTPases that are useful for inhibiting hyperprofilerative and neoplastic diseases.

Methods for treatment of cancer and hyperproliferative diseases are disclosed.
Abstract: A two-step thermochemical gas reduction process based on poly-cation oxides includes repeatedly cycling a thermal reduction step and a gas reduction step. In the thermal reduction the poly-cation oxide is heated to produce a reduced poly-cation oxide and oxygen. In the gas reduction step, the reduced poly-cation oxide is reacted with a gas to reduce the gas, while reoxidizing the poly-cation oxide. The poly-cation oxide has at least two distinct crystal structures at two distinct temperatures and is capable of undergoing a reversible phase transformation between the two distinct crystal structures. For example, the poly-cation oxide may be an entropy tuned mixed metal oxide, such as an entropy stabilized mixed metal oxide, where the entropy-tuning is achieved via change in crystal structure of one of more of the compounds involved. The gas reduction process may be used for water splitting, CO2 splitting, NOx reduction, and other gas reduction processes.

Abstract: A surgical access system facilitates access to a surgical site within a patient's body through an incision in the body. Surgical access systems can have at least one retention member and a fluid transportation member configured to deliver fluid to a surgical site or to remove fluid from a surgical site. In some embodiments, a surgical access device irrigates a surgical site to reduce surgical site infections and removes fluid from the surgical site to increase a physician's visibility into the surgical site.

Abstract: Particles, compositions, and methods that aid particle transport in mucus are provided. The particles, compositions, and methods may be used, in some instances, for ophthalmic and/or other applications. In some embodiments, the compositions and methods may involve modifying the surface coatings of particles, such as particles of pharmaceutical agents that have a low aqueous solubility. Such compositions and methods can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications. In certain embodiments, a pharmaceutical composition including such particles is well-suited for ophthalmic applications, and may be used for delivering pharmaceutical agents to the front of the eye and/or the back of the eye.

Abstract: Existing methods of producing high quality graphene/graphite oxides are generally accomplished by exfoliating graphite into flakes and oxidizing the graphite flakes with strong oxidizers under extreme conditions and require careful purification. The oxidizers are typically strong acids used in high concentrations at elevated temperatures requiring complicated purification processes to yield oxidized graphene/sheets. The existing processes can cost up to $12,000/gram. This invention uses a mild oxidant combined with mechanical processing where the sole products are oxidized graphite/graphene and water without the need for further purification.

Abstract: A method for diagnostic imaging with reduced contrast agent dose uses a deep learning network (DLN) [114] that has been trained using zero-contrast [100] and low-contrast [102] images as input to the DLN and full-contrast images [104] as reference ground truth images. Prior to training, the images are pre-processed [106, 110, 118] to co-register and normalize them. The trained DLN [114] is then used to predict a synthesized full-dose contrast agent image [116] from acquired zero-dose and low-dose images.

Abstract: This disclosure describes techniques for processing data bits using pseudo-random deterministic bit-streams. In some examples, a device includes a pseudo-random bit-stream generator configured to generate bit combinations encoding first and second numerical values based on a proportion of the data bits in the sequence that are high relative to the total data bits in the sequence. The device also includes a stochastic computational unit configured to perform a computational operation on the bit combinations and produce an output bit-stream having a set of data bits indicating a result of the computational operation, wherein the data bits of the output bit-stream represent the result based on a probability that any data bit in the set of data bits of the output bit-stream is high.
Abstract: A noise suppressor includes a first differential-mode transmission module, a second differential-mode transmission module and a common-mode absorption module.

The common-mode absorption module is electrically connected to a reference node, and is configured to absorb common-mode noise of the differential signal from at least one of the first differential-mode transmission module or the second differential-mode transmission module.
