Fifty-eight clinical isolates of Streptococcus pneumoniae serotype 6B, including 16 from Alaska, 14 from Arizona, 11 from Washington, and 17 from seven additional states, were analyzed. The antibiograms of these isolates were assigned to 10 antibiotic profiles based on their susceptibilities to penicillin, erythromycin, tetracycline, and trimethoprim-sulfamethoxazole. Thirty-two (55%) of these ...

A lossless beamsplitter has certain (complex-valued) probability amplitudes for sending an incoming photon into one of two possible directions. We use elementary laws classical and quantum optics to obtain general relations among the magnitudes phases these amplitudes. Proceeding examine a pair (nearly) single-mode wavepackets in number-states [Formula: see text] that simultaneously arrive at s...

We introduce a general bipartite-like representation and Schmidt decomposition of an arbitrary pure state $N$ indistinguishable fermions, based on states $M<N$ $(N-M)$ fermions. It is directly connected with the reduced $M$- $(N-M)$-body density matrices (DMs), which have same spectrum in such states. The concept $M$-body entanglement emerges naturally this scenario, generalizing that one-body ...

Did early modern European states make themselves sacred? The historian Paolo Prodi insisted that they did, whereas for the philosopher Giorgio Agamben sacred and secular power were so indistinguishable question was moot. This group of articles seeks to explain explore approaches these two accomplished Italian scholars problem sacralisation. introduction reviews context in which worked, sketches...

The effect of damping the longest streaks in wall-bounded turbulence is explored using numerical experiments. It found that long are not required for self-sustenance bursting process, which relatively little affected by their absence. In particular, there states fluctuations streamwise velocity have approximately same length as bursts, and thus presumably associated with bursts themselves, whil...

An increasingly important design constraint for software running on ubiquitous computing devices is security, particularly against physical methods such as side-channel attack. One well studied methodology for defending against such attacks is the concept of indistinguishable functions which leak no information about program control flow since all execution paths are computationally identical. ...

In 1916, Einstein postulated the existence of induced emission (einstrahlung), where a quantum of radiation from a light beam induced a molecule in an excited state to emit a quantum of radiation of the same frequency. The stimulating photon was unchanged by the ghostly interaction and the net effect of induced emission, which is now commonly known as stimulated emission, was indistinguishable ...

Intelligent agents perceive the world mainly through images captured at different time points. Being able to track objects from one image to another is fundamental for understanding the changes of the world. Tracking becomes challenging when there are multiple perceptually indistinguishable objects (PIOs), i.e., objects that have the same appearance and cannot be visually distinguished. Then it...
