Polio eradication: strengthening the weakest links.
Polio eradication, like all eradication efforts, is a gamble. If it fails, much of the money spent will have been wasted. If it succeeds, the world will reap a dividend. Success or failure and the magnitude of the dividend depend on a long chain of "weakest links." In this paper I identify these links and explain how the chain can be strengthened. A crucial vulnerability is the current plan to ...
متن کاملTemperature stress and plant sexual reproduction: uncovering the weakest links.
The reproductive (gametophytic) phase in flowering plants is often highly sensitive to hot or cold temperature stresses, with even a single hot day or cold night sometimes being fatal to reproductive success. This review describes studies of temperature stress on several crop plants, which suggest that pollen development and fertilization may often be the most sensitive reproductive stage. Tran...
متن کاملThe Weakest
The weakest specifunction has been introduced to generalise the notions of weakest prespecification and weakest parallel environment. It calculates the weakest specification function whose value refines the target when applied to a given component; thus it forms the basis for compositional refinement, an essential ingredient in program derivation. But unlike those previous calculii it is able t...
متن کاملCivil Commitment without Psychosis: The Law’s Reliance on the Weakest Links in Psychodiagnosis
“Psychotic” (Taken from the DSM-II) “Patients are described as psychotic when there mental functioning is sufficiently impaired to interfere grossly with their capacity to meet the ordinary demands of life. The impairment may result from a serious distortion in their capacity to recognize reality. Hallucinations and delusions, for example, may distort their perceptions. Alterations of mood may ...
متن کاملPredicting missing links and identifying spurious links via likelihood analysis
Real network data is often incomplete and noisy, where link prediction algorithms and spurious link identification algorithms can be applied. Thus far, it lacks a general method to transform network organizing mechanisms to link prediction algorithms. Here we use an algorithmic framework where a network's probability is calculated according to a predefined structural Hamiltonian that takes into...
