In this study, an efficient design method has been proposed for determining the optimal design structure of the dividing wall column. Preliminary design parameters are fixed on the basis of well-known shortcut method (Fenske-Underwood-Gilliland). The rigorous optimization is used to obtain the optimal design parameters of the divided wall column. Divided wall column has total eight design varia...

The most straightforward way to analyze investment-sector productivity developments is to construct a two-sector model with a sector-specific productivity shock. An often used modeling shortcut accounts for such developments using a one-sector model with shocks to the efficiency of investment in a capital accumulation equation. This shortcut is theoretically justified when some stringent condit...

In this work we present a novel concept of augmenting a search tree in a packet-processing system with an additional data structure, a Network of Shortcuts, in order to adapt the search to current input traffic patterns and significantly speed-up the frequently traversed search-tree paths. The method utilizes node statistics gathered from the tree and periodically adjusts the shortcut positions...

For efficiency reasons, words in electronic messages are sometimes formed by combining letters with numbers, as in gr8 for "great." The aim of this study was to investigate whether a digit incorporated into a letter-digit shortcut would retain its numerosity. A priming paradigm was used with letter-digit shortcuts (e.g., gr8) and matched pseudoshortcuts (e.g., qr8) as primes. The primes were pr...

A network supporting deep unsupervised learning is presented. The network is an autoencoder with lateral shortcut connections from the encoder to decoder at each level of the hierarchy. The lateral shortcut connections allow the higher levels of the hierarchy to focus on abstract invariant features. Whereas autoencoders are analogous to latent variable models with a single layer of stochastic v...

In this paper, we propose a new logarithmic filter grouping which can capture the nonlinearity of filter distribution in shallow CNNs. Residual identity shortcut is incorporated with the filter grouping to enhance the performance of shallow networks. The proposed logarithmic filter grouping is evaluated using a compact CNN structure with logarithmic group convolution modules which are composed ...

We present an efficient scheme to quickly generate three-qubit Greenberger–Horne–Zeilinger (GHZ) states by using three superconducting qubits (SQs) separated by two coplanar waveguide resonators (CPWRs) capacitively. The scheme is based on quantum Zeno dynamics and the approach of transitionless quantum driving to construct shortcuts to adiabatic passage. In order to highlight the advantages, w...

A shortcut to ortho-deuterated aldehydes: a catalytic directing group enables the manganese-catalyzed C–H activation and deuteration of benzaldehydes in one step.

There has been something of a quiet revolution occurring in biology related to a growing realization of the functional importance of sequences within irregular parts of biomolecules. For instance, it is now clear that ‘junk DNA’ is nothing of the kind: non-coding DNA and RNA are now known to play critical roles in all manner of biological processes1. It is also increasingly clear that disordere...

Neuronal activity results in the rapid induction of gene transcription through a series of defined molecular events. Madabhushi et al. describe an unexpected role for the cutting of promoter DNA by topoisomerase IIB to facilitate transcription of activity-induced genes.
