Methods and related systems are described for gamma-ray detection. A gamma-ray detector is made depending on its properties and how those properties are affected by the data analysis. Desirable properties for a downhole detector include; high temperature operation, reliable/robust packaging, good resolution, high countrate capability, high density, high Z, low radioactive background, low neutron cross-section, high light output, single decay time, efficiency, linearity, size availability, etc. Since no single detector has the optimum of all these properties, a downhole tool design preferably picks the best combination of these in existing detectors, which will optimize the performance of the measurement in the required environment and live with the remaining non-optimum properties. A preferable detector choice is one where the required measurement precision (logging speed) is obtained for all of the required inelastic elements and/or minimization of unwanted background signals that complicate the data analysis.

While the region's influence on mainstream hip-hop has gone overlooked for decades, a new generation of break-out artists are reclaiming their musical heritage and drawing national attention back to the area. In the hours leading up to their showcase at The Chapel in San Francisco's Mission District in late February, members of HBK Gang milled about the overcrowded green room, laughing, dancing, and taking selfies. The effervescent supergroup consists of more than a dozen East Bay rappers, singers, and producers mostly in their early twenties.…

Members of the International Longshore and Warehouse Union Local 10 who handle cargo at the Port of Oakland — one of the busiest US seaports — stopped work across the Bay Area today to protest against police brutality. Rallying near the gate of an idle port terminal, Bay Area longshore workers were joined by labor leaders representing BART train operators, city and county workers, port workers from Los Angeles, as well as hundreds of community members.

“There is an epidemic of police terror,” said Jack Heyman, a retired Oakland port worker.…

The Bay Area Vibez festival landed at the Port of Oakland this past weekend, bringing world-renowned reggae, electronic, and hip-hop artists to Middle Harbor Shoreline Park — a vast, open space that overlooks the San Francisco skyline. In its first year, the event arrived with a seemingly enormous budget and star-studded lineup that included living legends Stephen Marley, Damian Marley, and Nas.

But despite the festival’s grandiosity, the event ultimately felt like a way to capitalize on people’s nostalgia for bygone eras, prioritizing artists who haven’t released new material in years or are descendants of celebrated musicians.…

Roughly fifty demonstrators marched from Fruitvale BART on Friday night to Oakland City Hall in an anti-police rally called in response to the fatal shooting of Richard Perkins by Oakland police on November 15. But unlike protests earlier this year, police didn’t try to drive demonstrators onto the sidewalks to comply with Oakland Mayor Libby Schaaf’s policy banning nighttime street marches.…

On Saturday at Peter Thiel’s San Francisco home overlooking the Bay, protesters demonstrated against a collaboration between Immigration and Customs Enforcement and Palantir Technologies, a data-mining firm that Thiel co-founded. As reported in The Intercept, ICE will be using a new Palantir product called Investigative Case Management to to aid in its expanded deportation mission.…

Including a photo slideshow. Even at 10 a.m. this past Saturday morning, hours before a throng of anti-fascists and Trump-supporting white nationalists overtook downtown Berkeley’s streets, it was clear that most of the attendees were less interested in speeches, protesting, and free speech — and were mostly there just to tee-off on each other. Before the brawling began, officers stationed themselves at the entrances to downtown's "Peace Park."…
