Abstract: A method and apparatuses for a radiation detector apparatus, comprising a scintillator array comprising a plurality of scintillator crystals. The plurality of scintillator crystals includes a first scintillator crystal and a second scintillator crystal adjacent to the first scintillator crystal within the scintillator array. A photosensor array comprising a plurality of photosensors including a first photosensor configured to detect photons from the first scintillator crystal. A first separator positioned between the first scintillator crystal and the second scintillator crystal. First separator optically separates the first scintillator crystal and the second scintillator crystal such that the first photosensor detects photons from the first scintillator crystal and not from the second scintillator crystal.

Abstract: Disclosed herein are compounds that inhibit cullin-RING E3 ubiquitin ligase 4, a method of inhibiting the catalytic activity of a Cullin-RING E3 Ubiquitin (Ub) Ligase (CRL) in a cell, compositions comprising the inhibitor compounds, a method of treating a tumor, and a method of treating a subject for cancer.

Abstract: A guided pairing method includes generating a singles list by detecting a plurality of singles at a plurality of detector elements in a detector array, the plurality of singles falling within a plurality of detection windows; for each detection window of the plurality of detection windows in the singles list having exactly two singles of the plurality of singles, determining the line of responses (LORs) for each of the two singles of the plurality of singles; for each detection window of the plurality of detection windows in the singles list having more than two singles of the plurality of singles, determining all coincidences possible based on the more than two singles; generating a weight for said each coincidence of the coincidences based on the determined LORs for said each of the two singles of the plurality of singles; and pairing the more than two singles based on the generated weight for said each coincidence of the coincidences.

Abstract: A power-on operation execution method and apparatus are provided. The method includes: starting a processor of the chip in response to the chip being connected to a host and a frequency of a first clock signal of the chip being switched to a stable state; receiving a reset signal transmitted from the host, the reset signal being transmitted in response to a frequency of a second clock signal of the host being switched to a stable state; and executing a power-on operation in response to the reset signal, a time point at which the frequency of the first clock signal is switched to the stable state being earlier than a time point at which the frequency of the second clock signal is switched to the stable state.
