Two complex orthogonal space-time codes for eight transmit antennas" (2004). Two new constructions of complex orthogonal space-time block codes of order 8 based on the theory of amicable orthogonal designs are presented and their performance compared with that of the standard code of order 8. These new codes are suitable for multi-modulation schemes where the performance can be sacrificed for a...

Realistic stochastic simulation of hydro-environmental fluxes in space and time, such as rainfall, is challenging yet paramount importance to inform environmental risk analysis decision making under uncertainty. Here, we advance random fields by introducing the concepts general velocity anisotropy transformations. This expands capabilities so-called Complete Stochastic Modeling Solution (CoSMoS...

Background and Objectives: Community-acquired respiratory virus (CARV) infections pose a serious risk for lung transplant recipients (LTR) as they are prone to severe complications. When the COVID-19 pandemic hit Switzerland in 2020, government implemented hygiene measures general population. We investigated impact of these on transmission CARV Switzerland. Materials Methods: In this multicente...

The concept of Space-Time Crystals (STC), i.e. translational symmetry breaking in time and space, was recently proposed experimentally demonstrated for quantum systems. Here, we transfer this to magnons demonstrate a driven STC at room temperature. is realized by strong homogeneous micro-wave pumping micron-sized permalloy (Py) stripe directly imaged Scanning Transmission X-ray Microscopy (STXM...

This article proposes an algorithm which allows Alice to simulate the game played between her and Eve. Under condition that set of detectors assumes Eve have is sufficiently rich (e.g. CNNs), she has enabling avoid detection by a single classifier (e.g adversarial embedding, gibbs sampler, dynamic STCs), proposed converges efficient steganographic algorithm. possible using min max strategy cons...

Secure Two-Party Computation (STC) allows two mutually untrusting parties to securely evaluate a function on their private inputs. While tremendous progress has been made towards reducing processing overheads, STC still incurs significant communication overhead that is in fact prohibitive when no high-speed network connection is available, e.g., when applications are run over a cellular network...

We consider the problem of efficient simulation estimation of the density function at the tails, and the probability of large deviations for a sum of independent, identically distributed (i.i.d.), light-tailed and nonlattice random vectors. The latter problem besides being of independent interest, also forms a building block for more complex rare event problems that arise, for instance, in queu...

We propose a new space–time coding scheme for the quasi-static multiple-antenna channel with perfect channel state information at the receiver and no channel state information at the transmitter. In our scheme, codewords produced by a trellis encoder are formatted into space–time codeword arrays such that decoding can be implemented efficiently by minimum mean-square error (MMSE) decision–feedb...

Seaweed, a popular and abundant food ingredient mainly consumed in Asian countries, is a good source of bioactive compounds with anti-obesity effects. However, the anti-obesity effects of Sargassum thunbergii have not yet been established. In this study, we isolated six indole derivatives (STCs)-indole-2-carboxaldehyde (STC-1), indole-3-carboxaldehyde (STC-2), indole-4-carboxaldehyde (STC-3), i...

We have recently introduced a technique called “scheduler test case” (STC) as a practical means for bridging the gap between scheduling algorithms and scheduler implementations in time-triggered embedded systems. The technique was originally applied to single-processor embedded designs employing “time-triggered co-operative” (TTC) architectures aimed at highly predictable real-time systems. It ...
