[1] The applicability of the Rayleigh-Gans approximation (RGA) for scattering by snowflakes is studied in the microwave region of the electromagnetic spectrum. Both the shapes of the single ice crystals, or monomers, and their amounts in the modeled snowflakes are varied. For reference, the discrete-dipole approximation (DDA) is used to produce numerically accurate solutions to the single-scatt...

To the Editor: I read with interest the article by Furlan & Brueur on "Central Nervous System Complications of Open Heart Surgery". DDA is a variant of atherosclerosis which includes patients with "brittle aortas" wherein showers of cholesterol emboli repeatedly occur spontaneously or from trauma. I believe it is possible that a relatively high percentage of patients who suffered major embolic ...

Many breast cancer deaths result from tumors acquiring resistance to available therapies. Thus, new therapeutic agents are needed for targeting drug-resistant breast cancers. Drug-refractory breast cancers include HER2+ tumors that have acquired resistance to HER2-targeted antibodies and kinase inhibitors, and "Triple-Negative" Breast Cancers (TNBCs) that lack the therapeutic targets Estrogen R...

Since the packet is transmitted to a set of relaying nodes in opportunistic routing strategy, so the transmission delay and the duplication transmission are serious. For reducing the transmission delay and the duplicate transmission, in this paper, we propose the delay based duplication transmission avoid (DDA) coordination scheme for opportunistic routing. In this coordination scheme, the cand...

Mapping audio data to feature vectors for the classification, retrieval or identification tasks presents four principal challenges. The dimensionality of the input must be significantly reduced; the resulting features must be robust to likely distortions of the input; the features must be informative for the task at hand; and the feature extraction operation must be computationally efficient. I...

The ESAT-6 antigen from Mycobacterium tuberculosis is a dominant target for cell-mediated immunity in the early phase of tuberculosis (TB) in TB patients as well as in various animal models. The purpose of our study was to evaluate the potential of ESAT-6 in an experimental TB vaccine. We started out using dimethyl dioctadecylammonium bromide (DDA), an adjuvant which has been demonstrated to be...

LC-MS/MS has emerged as the method of choice for the identification and quantification of protein sample mixtures. For very complex samples such as complete proteomes, the most commonly used LC-MS/MS method, data-dependent acquisition (DDA) precursor selection, is of limited utility. The limited scan speed of current mass spectrometers along with the highly redundant selection of the most inten...

Microarray technology has made it possible to simultaneously study the abundance, interactions, and functions of potentially tens of thousands of biological molecules. From its earliest use in DNA microarrays, where only nucleic acids were captured and detected on the arrays, applications of microarrays now extend to those involving biomolecules such as antibodies, proteins, peptides, and carbo...

Dynamic difficulty adjustment (DDA) is a set of techniques that aim to automatically adapt the video game based on player’s performance. This article presents methodology for DDA using ideas from theory flow and case-based reasoning (CBR). In essence, we are looking generate sessions with similar evolution previous have produced in players skill level. We propose CBR approach dynamically assess...

In recent years, earthquake rockfalls have occurred frequently all over the world, resulting in heavy casualties and property losses. Unfortunately, research on rockfall dynamics upon events is still rare due to limited field experimental data, restricted numerical simulations of only two dimensions. order primarily reveal role earthquakes rockfall, this study focused stability rock blocks an i...
