Models of unsupervised correlation-based (Hebbian) synaptic plasticity are typically unstable: either all synapses grow until each reaches the maximum allowed strength, or all synapses decay to zero strength. A common method of avoiding these outcomes is to use a constraint that conserves or limits the total synaptic strength over a cell. We study the dynamical e ects of such constraints. Two m...

. Demam berdarah dengue(DBD) adalah penyakit infeksi virus akut yang disebabkan oleh dengue. Provinsi Sumatera Barat merupakan salah satu provinsi di Indonesia memiliki angka penderita DBD cukup tinggi. Penelitian ini bertujuan untuk mengelompokkan kabupaten/kota berdasarkan faktor terkait kejadian yakni banjir, penampungan air, fasilitas dan tenaga kesehatan penduduk miskin. Metode digunakan d...

Abstract Physical models of anatomical structures can be made using Additive Manufacturing (AM) or Subtractive (SM). The advantage subtractive techniques over additive ones is the possibility maintaining homogeneity and consistency processed material, which extremely important in case medical devices. Currently, a geometrically complex model even on simple, 3-axis CNC machine tool. However, oft...

Molecular techniques previously used for genome comparisons of closely related bacterial species could prove extremely valuable for comparisons of complex microbial communities, or metagenomes. Our study aimed to determine the breadth and value of suppressive subtractive hybridization (SSH) in a pilot-scale analysis of metagenomic DNA from communities of microorganisms in the rumen. Suppressive...

The first phase of the determination of the primary structure of chromatographically homogeneous bovine pancreatic deoxyribonuclease A has been the isolation of 23 principal peptides from tryptic digests of the reduced and alkylated protein and 20 peptides from a chymotryptic hydrolysate. Seven of the latter series provide information on the ordering of peptides of the tryptic series. The resul...

In this paper, a 5.1-channel audio recording method is proposed by applying the mid-side (MS) stereo recording technique to a coincident microphone array. The coincident microphone array consists of a backward-facing cardioid microphone and the MS microphone array which is composed of a pair of forward-facing cardioid and sideways-facing figure-eight microphones. These 3 microphones produce two...

(150-250 words) Liquid delivery through interconnected pore network is essential for various interfacial transport applications ranging from energy storage to evaporative cooling. The liquid transport performance in porous media can be significantly improved through the use of hierarchical morphology that leverages transport phenomena at different length scales. Traditional surface engineering ...

Two neural network models, called clustering-RBFNN and clustering-BPNN models, are created for estimating the work zone capacity in a freeway work zone as a function of seventeen different factors through judicious integration of the subtractive clustering approach with the radial basis function (RBF) and the backpropagation (BP) neural network models. The clustering-RBFNN model has the attract...
