Heralded single photon source (HSPS) is an important way in generating genuine photon, having advantages of experimental simplicity and versatility. However, HSPS intrinsically suffers from the trade-off between heralded rate purity. To overcome this, one can apply multiplexing technology different degrees freedom to enhance performance HSPS. Here, by employing spectral active feed-forward mani...

The voltage-dependent properties that have been directly demonstrated in Purkinje cell and hippocampal pyramidal cell dendrites play an important role in the integrative capacities of these neurons. By contrast, the properties of neocortical pyramidal cell dendritic membranes have been more difficult to assess. Active dendritic conductances near sites of synaptic input would have an important e...

Functional magnetic resonance imaging (fMRI) of the hand representation in primary somatosensory cortex (area 3b) of macaque monkeys revealed an ipsilateral hand input undetected by most previous studies. Ipsilateral responses had a hemodynamic signature indistinguishable from that of contralateral hand responses. We explored the neural mechanisms of the fMRI effects using a second derivative a...

We derive a closed-form expression for the capacity of the additive-Gaussian-noise memoryless channel with binary input. The capacity expression that we obtain contains an infinite series. Truncation of the series -for computation reasonsat an odd or even number of terms results in a lower or upper, respectively, bound on the channel capacity; we prove that the tightness of the bound increases ...

Visual input during development seems crucial in tactile spatial perception, given that late, but not congenitally, blind people are impaired when skin-based and tactile external representations are in conflict (when crossing the limbs). To test whether there is a sensitive period during which visual input is necessary, 14 children (age = 7.95) and a teenager (LM; age = 17.38) deprived of early...

A finite number of users communicating through a broadcast channel is considered. Each user has a buffer of infinile capacity, and a user randomly accesses the channel ( ALOHA-type protocol). Moreover, only one packet per user might be sent in an access time. Both symmetric and asymmetric models are considered, that is, we assume either indistinguishable or distinguishable users. An exact analy...

In this paper, we study the security notions of verifiably committed signatures by introducing privacy and cut-off time, and then we propose the first scheme which is provably secure in the standard complexity model based on the strong RSA assumption. The idea behind the construction is that given any valid partial signature of messages, if a co-signer with its auxiliary input is able to genera...
