Sevgi Gokce Kafali - MSc Thesis Presentation

Sevgi Gokce Kafali has successfully defended her MSc thesis on April 17th, 2018. The title of her thesis is "PHASE-CORRECTING DENOISING FOR DIFFUSION MAGNETIC RESONANCE IMAGING." This work proposes a simultaneous solution to low-SNR and motion-induced phase problems experienced in diffusion MRI, via a novel phase-correcting non-local means (PC-NLM) filter. Sevgi's first-author paper on this work was recently published in Magnetic Resonance in Medicine (see this link). Sevgi will join University of California, Los Angeles (UCLA) in September for her PhD studies.

Bismillah Nasir Ashfaq has successfully defended his MS thesis on 29th of March 2018. The title of the thesis is "A GATE MODULATED DIGITALLY CONTROLLED MODIFIED CLASS-E AMPLIFIER FOR ON-COIL APPLICATION IN MRI." This highly innovative work may have applications beyond MRI. Nasir is returning to his home, Pakistan, to join Fatima. They are expecting a baby anytime. Congratulations to Nasir for the excellent thesis defense. 

Together with Dr. Algin, five Bilkent University faculty (Ozcan Ozturk,Onur Tokel,Ferdi Karadas,Barbaros Cetin,Meral Ugur Cinar) won the award. This award is given to the young faculty members in order to praise their scientific work by the Science Academy. Earlier, Drs. Saritas and Cukur won this award in 2016 and 2017, respectively.  Ergin Atalar of UMRAM is a member of the Academy which was formed in Nov 2011 as an independent non-governmental organization to promote, practice and uphold the principles of scientific merit, freedom and integrity. 

European patent application (WO2015167408)(PCT/TR2014/000248) entitled "NANOPARTICLE FORMULATION CONTAINING FARNESYLTHIOSALICYCLIC ACID" has been concluded positively and the registration decision has been finalized. Farnesylthiosalicylic acid (Salirasib, FT A), a new generation antineoplastic agent, is a specific inhibitor of Ras protein, which presents in high rate in most of malignant tumors.The patentable study is a targeted chemotherapy  to change the disposition, uptake or efficacy of antineoplastic drugs by providing more damages to tumor cells rather than normal cells. Former UMRAM researcher Taner Demir and UMRAM  Professor Kader Karlı Oguz are among the invention owners.  Other  authors  includes  Sibel PEHLİVAN, İmran VURAL, Melike Mut AŞKUN, Figen SÖYLEMEZOĞLU of Hacettepe University Medical School and Abbas KAFFASHI, Sevda LÜLE, Hüsnü KOŞUCU, Can SARISÖZEN.  See: 

Utku Kaya (Graduate Researcher at UMRAM) successfully defended his PhD thesis entitled “Neural Mechanisms Underlying Sub-second Crossmodal Time Perception”. He aimed to understand neural correlates of auditory influences on perceived visual timing, visual time intervals and apparent motion. To achieve this aim, he designed precise experiments within sub-second range and provided comprehensive EEG analyses.

We would like to congratulate Fatima Tu Zahra for receiving the master of science degree from Bilkent EEE. Her thesis title is "Highly Efficient 300 W Modified Class-E RF Amplifiers for 64 MHz Transmit Array System". She managed her 2x300W amplifiers work in MRI scanner as in TxArray mode. Her supervisor was Ergin Atalar. She is planning to return back to Pakistan. Her husband Nasir will be joining her in the early summer of 2018. 

UMRAM researchers have recently published a journal article in Experimental Brain Research. In their study, they focused on brain mechanisms and principles coordinating crossmodal and intramodal perceptual grouping. By designing different experiments on perceived speed, they found that certain spatial grouping principles of vision can take precedence over audiovisual interactions in time. Moreover, their findings indicated that the effects of sound timing on perceived speed exist in different spatial configurations. These behavioral findings have implications for designing systems that take the multisensory nature of motion perception and speed estimation into account.
