Topic: "Complex network in big data problems"


Systems as diverse as brain or genetic networks are best described as networks with complex topology. A common topological property of many large networks is that the network connectivity generated by a few influential nodes follow a scale-free distribution. The scale-free (power-law) distribution is given by the probability that one vertex in the network interacts with  other vertices decays as a power law, following


It has been well understood that two important general components, growth and preferential attachment, generate such scale-free distribution. The growth is defined as the increase of the number of nodes of the network over time and the preferential attachment as assigning the probability  in a way that at a given time a new vertex connects vertex  proportional to the already given connectivity  of that vertex. In this talk, we discuss scale-free network and the two components in statistical point of view and then propose test statistics which enable to carry out formal statistical test against scale-free network.

We also discuss scale-free distribution in various types of big data problems, which includes social network, computer network, economic crisis, motor learning, language learning, city heavy rain, genetics and brain network.

Keynote Speaker (2)

Delmar R. Arzabal, MSc

Radiation Oncology Medical Physicist

Short Bio/Description:

Driven by his passion for science, Delmar Arzabal specialized in applied physics. This was further honed by his experience as a teacher at the La Salle Green Hills, and extensive training at the Philippines Nuclear Research Institute. He pursued and graduated Master of Science in Applied Physics major in Medical Physics from the University of Santo Thomas, and wrote his thesis about Phantom and Clinical Evaluation of Combined Image Reconstruction Parameter of Philips Gemini TF 64 PET/CT Imaging System, as a recipient of the scholarship of the Department of Science and Technology. He has presented his work and research findings to various conferences both local and international.

He is currently the Radiation Oncology Medical Physicist of the Perpetual Help Medical Center – Biñan, mainly in charge of the radiation therapy treatment plans and quality assurance of the linear accelerator.


“Medical Imaging in Radiation Oncology and Beyond”


Modern medical diagnosis and treatment heavily rely on the imaging modality. In the field of medical physics, different imaging modalities, particularly those that utilize electromagnetic waves, are thoroughly studied. X-rays are commonly used and its applications vary extensively based on the complexity of the target volume to give 2D and 3D images. 3-dimensional images are easily rendered using Computed Tomography (CT) scan. The data of which can be integrated with Positron Emission Tomography (PET) and Single-Photon Emission Computed Tomography (SPECT) for better tumor localization and cancer prognosis.

Advancements in radiotherapy allow the medical physicists to target and treat the tumor volume more accurately. However, contouring the actual body part still highly depends on the image quality. Various image quality enhancements can be done through the modification virtual and physical parameters of data acquisition. Image reconstruction can be analytic or iterative. Both methods utilize algorithms, commonly the Fourier Transform in 1 and 2 dimensions. Mathematical computation and strategic estimation have considerable effects on the reconstructed image.

The CT information can be further differentiated to isolate a chosen part and to export data for 3D printing.  This permits customized treatment accessories which can improve radiation dose delivery to patients. The utilization of the image data to 3D print a treatment accessory or replicate an anatomical part is not only useful for radiation oncology, but extends to biomedical engineering and other allied sciences.
