The aim of this study was to evaluate the odontogenic potential of undifferentiated pulp cells (OD-21 cell line) through chemical stimuli in vitro. Cells were divided into uninduced cells (OD-21), induced cells (OD-21 cultured in supplemented medium/OD-21+OM) and odontoblast-like cells (MDPC-23 cell line). After 3, 7, 10 and 14 days of culture, it was evaluated: proliferation and cell viability...

43 In this research, we propose a methodology to develop OD matrices using mobile phone Call 44 Detail Records (CDR), which consist of time stamped tower locations with caller IDs, and 45 limited traffic counts. CDR from 2.87 million users from Dhaka, Bangladesh over a month and 46 traffic counts from 13 key locations of the city over 3 days of the same period are used in this 47 regard. The in...

The Hadamard conjecture is that Hadamard matrices exist for all orders 1,2, 4t where t 2 1 is an integer. We have obtained the following results which strongly support the conjecture: (i) Given any natural number q, there exists an Hadamard matrix of order 2 q for every s 2 [2log2 (q 3)]. (ii) Given any natural number q, there exists a regular symmetric Hadamard matrix with constant diagonal of...

Origin-Destination (OD) trip matrices describe the patterns of traffic behavior across the network and play a key role as primary data input to many traffic models. OD matrices are a critical requirement, either in static or dynamic models for traffic assignment. However, OD matrices are not yet directly observable; thus, the current practice consists of adjusting an initial or a priori matrix ...

Short-term passenger flow forecasting is an important component of transportation systems. The forecasting result can be applied to support transportation system operation and management such as operation planning and revenue management. In this paper, a divide-and-conquer method based on neural network and origin-destination (OD) matrix estimation is developed to forecast the short-term passen...

Collagen is the most prominent protein in the human body, making up 30% of the total protein content. Quantitative studies have shown structural differences between collagen fibers of the normal and diseased tissues, due to the remodeling of the extracellular matrix during the pathological process. The dominant orientation, which is an important characteristic of collagen fibers, has not been t...

A subarea analysis capability is needed in conjunction with dynamic network analysis models to allow consideration and rapid evaluation of a large number of scenarios and support transportation network planning and operations decisions for situations that may not require analysis on a complete network representation. Focusing on how to provide an up-to-date time-dependent OD demand matrix for t...

We prove that if there Hadamard of order hand n divisible by 4 then there exist two disjoint ihn), whose sum is a (1,-1) matrix and a complex Hadamard matrix of order furthermore, there exists an 0 D(mj 81,82, ' .. ,8/) for even m then there exists an OD(lhnm;
