The intelligence community (IC) is asked to predict outcomes that may often be inherently unpredictable-and is blamed for the inevitable forecasting failures, be they false positives or false negatives. To move beyond blame games of accountability ping-pong that incentivize bureaucratic symbolism over substantive reform, it is necessary to reach bipartisan agreements on performance indicators t...

The miniature Ping (mPing) is a recently discovered endogenous miniature inverted repeat transposable element (MITE) in rice, which can be mobilized by tissue culture or irradiation. It is reported here that mPing, together with one of its putative transposase-encoding partners, Pong, was efficiently mobilized in somatic cells of intact rice plants of two distinct cultivars derived from germina...

After preparing this note, the paper [IT] was discovered which covers the more general situation of “expansive foliations”, and in codimension one their result includes Theorem1.2. We note that the proof given here is more self–contained and goes into more detail about the construction of the “ping-pong table” in the topological case, which the reader might still find of interest.

l. Studies using clorgyline, deprenyl and semicarbazide as inhibitors showed that carp heart homogenate contained a new type of monoamine oxidase (MAO) and a clorgylineand deprenyl-resistant amine oxidase (CRAO). 2. The deamination of monoamines by carp heart MAO proceeded in two steps by a doubledisplacement (ping-pong) mechanism. 3. The rC, values of the MAO for oxygen (K, values) with tyrami...

A twin inhibition is observed for the esterification reaction between ethanol and isovaleric acid using immobilized lipase from Rhizomucor miehei in hexane and in mixed solvent system. The observed bi-substrate inhibition pattern follows a Ping-Pong Bi-Bi mechanism with dead-end inhibition of enzyme by both the substrates. An increase in Km value for alcohol in mixed solvent (0.645 M) than in h...

Algorithms for the maximum flow problem can be grouped into two categories: augmenting path algorithms [9], and preflow push algorithms [11]. Preflow push algorithms are characterized by a drawback known as ping pong effect. In this paper we present a technique that allows to avoid such an effect and can be considered as an approach combining the augmenting path and preflow push methods. An ext...

A novel system for realtime range and geometry estimation of a group of smartphones colocated in a shared physical space is presented. The system uses off-the-shelf devices and employs audible signals to estimate inter-device (pairwise) distances. Coordinated sound synthesis and processing of a pair of pitched sounds allows to estimate the distance between two devices based on the travel time. ...

Cortical cell polarity controls mitotic spindle orientation in many cell types. In this issue of Cell, it is turned around and shown that the transfer of polarity information between the cortex and the spindle is not just one way. In Drosophila neuroblasts, the spindle also has polarizing activity on the cortex.
