Blunting the Spike: the CV Minimum Period
The standard picture of CV secular evolution predicts a spike in the CV distribution near the observed short–period cutoff P0 ≃ 78 min, which is not observed. We show that an intrinsic spread in minimum (‘bounce’) periods Pb resulting from a genuine difference in some parameter controlling the evolution can remove the spike without smearing the sharpness of the cutoff. The most probable second ...
متن کاملNeuronal Communication: Firing Spikes with Spikes
Spikes of single cortical neurons can exert powerful effects even though most cortical synapses are too weak to fire postsynaptic neurons. A recent study combining single-cell stimulation with population imaging has visualized in vivo postsynaptic firing in genetically identified target cells. The results confirm predictions from in vitro work and might help to understand how the brain reads si...
متن کاملBlunting Differential Attacks on PIN Processing APIs
We propose a countermeasure for a class of known attacks on the PIN processing API used in the ATM (cash machine) network. This API controls access to the tamper-resistant Hardware Security Modules where PIN encryption, decryption and verification takes place. The attacks are differential attacks, whereby an attacker gains information about the plaintext values of encrypted customer PINs by mak...
متن کاملOn the Blunting Method in the Verified Integration of ODEs
Verified methods for the integration of initial value problems (IVPs) for ODEs aim at computing guaranteed error bounds for the flow of an ODE and maintaining a low level of overestimation at the same time. This paper is concerned with one of the sources of overestimation: a matrixvector product describing a parallelepiped in the phase space. We analyze the socalled blunting method developed by...
متن کاملExtrasomatic spikes recorded from cat motoneurons. Possible dendritic spikes.
Extrasomatic (ES-) spikes were recorded in motoneurons in cats anesthetized with pentobarbital sodium and immobilized with d-tubocurarine. ES-spikes, 40-79 mV in amplitude, were distinguished from intrasomatic spikes by their differences in responses to a train of 8 pulses at 500 Hz given to the L 7 or S 1 ventral root. In 23 motoneurons 3-6 different spikes could be recorded from the same site...
