For instance, the first counterexample must be odd because f(2n) = n, smaller than 2n; and it must be 3 mod 4 because f 2 (4n + 1) = 3n + 1, smaller than 4n + 1. For each starting value a which is not a counterexample to the Collatz conjecture, there is a k for which such an inequality holds, so checking the Collatz conjecture for one starting ...
1,3,4-Oxadiazole derivatives can be synthesized in a variety of ways. One pathway is from oxidation of tetrazoles in the presence of aldehydes. Similarly, the reaction of tetrazoles with acyl chlorides provides oxadiazoles. Both methods involve the release of N 2. See also. Furazan (1,2,5-oxadiazole) References
Where the problem is atrioventricular block (AVB) the pacemaker is required to detect (sense) the atrial beat and after a normal delay (0.1–0.2 seconds) trigger a ventricular beat, unless it has already happened – this is VDD mode and can be achieved with a single pacing lead with electrodes in the right atrium (to sense) and ventricle (to ...

Cardiology. Heart failure with preserved ejection fraction ( HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1 ...
