As a microtubule-organizing center, the centrosome undergoes a dramatic increase in size - via expansion of the pericentriolar material - during mitosis. Recent work reveals shared assembly properties of a protein scaffold that facilitates and supports this expansion, a process critical to spindle assembly.

The delivery route for the Bandung 40400 Mail Processing Center is determined based on estimation using zoning system, and this may trigger delays. This happens because of each vehicle can only deliver to one distribution center at a time. makes load factor level utilization below 20%. study aims obtain optimal schedule improve efficiency increase capacity utilization. quantitative research met...

We present Cypress, a novel framework to archive and query massive time series streams such as those generated by sensor networks, data centers, and scientific computing. Cypress applies multi-scale analysis to decompose time series and to obtain sparse representations in various domains (e.g. frequency domain and time domain). Relying on the sparsity, the time series streams can be archived wi...

A measurement of the strong coupling constant αs using the event-shape variable y3 (the differential two-jet rate) in the reaction e+e− → hadrons is presented. The analysis is based on data from the TPC/Two-Gamma detector at the PEP e+e− storage ring taken between 1984 and 1986 at a center-of-mass energy of Ecm = 29 GeV. A value of αs(29 GeV) = 0.160 ± 0.012 is obtained, where the error is the ...

Recently, we have proposed that the dense local and sparse long-range connectivity of the visual cortex accounts for the rapid and robust transformation of visual stimulus information into a temporal population code, or TPC. In this paper, we combine the canonical cortical computational principle of the TPC model with two other systems: an attention system and a hippocampus model. We evaluate w...

Motivated by the applications in routing in data centers, we study the problem of expressing an n × n doubly stochastic matrix as a linear combination using the smallest number of (sub)permutation matrices. The Birkhoff-von Neumann decomposition theorem proves that there exists such a decomposition, but does not give a representation with the smallest number of permutation matrices. In particul...

We study the frequency-selective broadcast channel with confidential messages (BCC) where the transmitter sends a confidential message to receiver 1 and a common message to receivers 1 and 2. In the case of a block transmission of N symbols followed by a guard interval of L symbols, the frequency-selective channel can be modeled as a N × (N + L) Toeplitz matrix. For this special type of multipl...

Multiplicative preconditioning is a popular tool for handling linear systems of equations provided the relevant information about the associated singular values is available. We propose using additive preconditioners, which are readily available for both general and structured ill conditioned input matrices and which preserve matrix structure. We introduce primal and dual additive preconditioni...

Sampling and reconstruction of generic multivariate functions is more efficient on non-Cartesian root lattices, such as the BCC (Body-Centered Cubic) lattice, than on the Cartesian lattice. We introduce a new n × n generator matrix A that enables, in n variables, for efficient reconstruction on the non-Cartesian root lattice An by a symmetric box-spline family M r . A2 is the hexagonal lattice ...
