In this paper, we address semi-supervised sentiment learning via semi-stacking, which integrates two or more semi-supervised learning algorithms from an ensemble learning perspective. Specifically, we apply metalearning to predict the unlabeled data given the outputs from the member algorithms and propose N-fold cross validation to guarantee a suitable size of the data for training the meta-cla...

3D integrated circuits (3DICs) with through-silicon vias (TSVs) are an important direction for semiconductor-based products and “More than Moore” scaling. However, 3DICs bring simultaneous challenges of reliability (power and temperature in stacks of thinned die) as well as variability (performance and power) in advanced technology nodes. In this paper, we study variability-reliability interact...

A solid water phase commonly known as "cubic ice" or "ice I(c)" is frequently encountered in various transitions between the solid, liquid, and gaseous phases of the water substance. It may form, e.g., by water freezing or vapor deposition in the Earth's atmosphere or in extraterrestrial environments, and plays a central role in various cryopreservation techniques; its formation is observed ove...

A previous paper detailed a novel algorithm, ε-machine spectral reconstruction theory (εMSR), that infers pattern and disorder in planar-faulted, close-packed structures directly from X-ray diffraction patterns [Varn et al. (2013). Acta Cryst. A69, 197-206]. Here εMSR is applied to simulated diffraction patterns from four close-packed crystals. It is found that, for stacking structures with a m...

We present an assessment of the accuracy common operations performed in $21$-cm spectral line stacking experiments. To this end, we generate mock interferometric data surveying 21-cm emission at frequency $1310<\nu<1420$ MHz ($0.005<z<0.084$) and covering area $\sim 6$ deg$^2$ sky, mimicking observational characteristics real MeerKAT observations. find that primary beam correction accounts for ...

G-quadruplexes constitute a class of nucleic acid structures defined by stacked guanine tetrads (or G-tetrads) with guanine bases from neighboring tetrads stacking with one another within the G-tetrad core. Individual G-quadruplexes can also stack with one another at their G-tetrad interface leading to higher-order structures as observed in telomeric repeat-containing DNA and RNA. In this study...

Consistent relative stacking interaction energies have been calculated for triply ionised dinucleotide structures in the g-gconformation. For UpAp, ApUp, CpAp and ApCp , the stacking energies in the ZKE approximation including zeropoint energies were found to be -0.031, -0.028, -0.033, -0.033 +/0.001 h, respectively. The corresponding free energy values at 298.15 K were found to be: -0.017, -0....

The freezing of water to ice is fundamentally important to fields as diverse as cloud formation to cryopreservation. At ambient conditions, ice is considered to exist in two crystalline forms: stable hexagonal ice and metastable cubic ice. Using X-ray diffraction data and Monte Carlo simulations, we show that ice that crystallizes homogeneously from supercooled water is neither of these phases....

The idea of ensemble methodology is to build a predictive model by integrating multiple models. It is well-known that ensemble methods can be used for improving prediction performance. Researchers from various disciplines such as statistics, machine learning, pattern recognition, and data mining have considered the use of ensemble methodology. Stacking is a general ensemble method in which a nu...

This study reports a new stacking method for assembling a 3-D microprobe array. To date, 3-D array structures have usually been assembled with vertical spacers, snap fasteners and a supporting platform. Such methods have achieved 3-D structures but suffer from complex assembly steps, vertical interconnection for 3-D signal transmission, low structure strength and large implantable opening. By a...
