A bstract Collider observables involving heavy particles are subject to large logarithmic terms near threshold, which must be summed all orders in perturbation theory obtain sensible results. Relatively recently, this resummation has been extended next-to-leading power the threshold variable, using a variety of approaches. In paper, we consider partonic channels that turn on only at power, and ...

We study Random 2-SAT problem, in which 2-CNFs are sampled from a wide range of non-uniform distributions, including heavy-tailed using random model that is quite different the standard uniform 2-SAT. This SAT so-called configuration model, given by distribution ξ for degree (or number occurrences) each variable. To generate formula variable , generating several clones Then 2-clauses created ch...

A model of internal transport barriers ~ITB! is developed that, in addition to the typical features of ITB models ~the phase transition character with a power threshold, barrier front propagation, etc.!, exhibits an oscillatory/bursty behavior close to the transition. This behavior comes from the competition between the driving and suppression mechanisms for the turbulence. The onset of the osc...

The Content Addressable Memory (CAM) is a class of memory that allows access by data instead of by physical address. On a read access to a CAM, embedded into a processor cache, each word is compared in a broadcast mode, to see if it matches the requested data; thus requiring only one access. Due to their parallel pattern matching property, CAMs are gaining increasing importance over Random Acce...

Threshold implementations allow to implement circuits using secret sharing in a way to thwart side-channel attacks based on probing or power analysis. It was proven they resist to attacks based on glitches as well. In this report, we show the limitations of these results. Concretely, this approach proves security against attacks which use the average power consumption of an isolated circuit. Bu...

MTCMOS is an effective circuit level technique which has multiple threshold voltages in order to optimize delay and power. Low threshold voltage MOSFETs enhance the speed performance, while the high threshold voltages MOSFETs minimize the static leakage power. The above technique is adopted in parallel multiplier with level shifter interface which gives supply voltage for MTCMOS transistors. By...

In video streaming services, the playout begins when the queue length of the receiver buffer is above a threshold. This threshold must be large to reduce the buffer underflow probability and absorb the bit rate variations caused by the wireless channel. On the other hand, it is important to reduce this threshold in order to reduce the initial playout delay and also the size of the receiver buff...

Extremely low voltage operation near or below threshold voltage is a key circuit technology to improve the energy efficiency of information systems and to realize ultra-low power sensor nodes. However, it is difficult to operate conventional analog circuits based on amplifier at low voltage. Furthermore, PVT (Process, Voltage and Temperature) variation and random Vth variation degrade the minim...

In this paper we present efficient procedures for delay constrained minimization of the power due to leakage in CMOS digital circuits for a dual threshold voltage (VT ) technology. The availability of two or more threshold voltages on the same chip provides a new opportunity for circuit designers to make tradeoffs between power and delay. We present two efficient procedures that take as input a...
