Genetic admixture is central to primate evolution. We combined 50 years of field observations of immigration and group demography with genomic data from ~9 generations of hybrid baboons to investigate the consequences of admixture in the wild. Despite no obvious fitness costs to hybrids, we found signatures of selection against admixture similar to those described for archaic hominins. These patterns were concentrated near genes where ancestry is strongly associated with gene expression. Our analyses also show that introgression is partially predictable across the genome. This study demonstrates the value of integrating genomic and field data for revealing how “genomic signatures of selection” (e.g., reduced introgression in low-recombination regions) manifest in nature; moreover, it underscores the importance of other primates as living models for human evolution. 

The paper summarizes the single-event upset (SEU) results obtained from neutron testing on the UltraScale+ MPSoC ZU9EG device. This complex device contains a large amount of programmable logic and multiple processor cores. Tests were performed on the programmable logic and the processing system simultaneously. Estimates of the single-event upset neutron cross section were obtained for the programmable logic CRAM, BRAM, OCM memory, and cache memories. During the test, no processor crashes or silent data corruptions were observed. In addition, a processor failure cross section was estimated for several software benchmark operating on the various processor cores. Several FPGA CRAM scrubbers were tested including an external JTAG, the Xilinx “SEM” IP, and the use of the PCAP operating in baremetal. In parallel with these tests, single-event induced high current events were monitored using an external power supply and monitoring scripts. 

This study examines the single-event response of Xilinx 16nm FinFET UltraScale+ FPGA and MPSoC device families. Heavy-ion single-event latch-up, single-event upsets in configuration SRAM, BlockRAM™ memories, and flip-flops, and neutron-induced single-event latch-up results are provided.
