We consider a bipartite scenario where two parties hold ensembles of 1/2-spins which can only be measured collectively.We give numerical arguments supporting the conjecture that in this scenario no Bell inequality can be violated for arbitrary Lip Liner numbers of spins if only first order moment observables are available.We then give a recipe to a
Abstract Background We present an analysis of interviews with Skewers 27 self-identified progressive white-male physics faculty and graduate students discussing race and gender in physics.White cis men dominate most STEM fields and are particularly overrepresented in positions of status and influence (i.e., full professors, chairs, deans, etc.), po
Navigation and traffic services such as Google Maps, Bing Maps, and Apple Maps have become increasingly popular for their ability to calculate the shortest path, provide real-time traffic updates, recommend nearby points of interest, and suggest multi-modal route options based on user constraints.However, while these services offer convenience and
A boring bar is a tool used to install cutters and transfer power during boring.Because the boring bar in a narrow workspace is usually slender, chatter often occurs in the boring process.To improve the chatter stability of the boring bar, researchers have designed composite material boring bars with high dynamic stiffness to meet the requirements
Visual-based brain-computer interface (BCI) enables people to communicate with others by spelling words from the brain and helps professionals recognize targets in large numbers of images.P300 signals evoked by different types of stimuli, such as words or images, may vary significantly in terms of both amplitude and latency.A unified approach is re
