FW: BME distinguished lecture series, Dr. Susan Cox (King's College London)
by Turner, Jaime J 27 Nov '18

27 Nov '18

Purdue University Weldon School of Biomedical Engineering Distinguished Lecture Series Wednesday, November 28, 2018 9:30-10:20am MJIS 1001 *and via Zoom meeting at IUPUI Seeing and believing at super-resolution Susan Cox, Ph.D. Randall Division of Cell and Molecular Biophysics Guy’s Campus, King’s College London London, UK, SE1 1UL [cid:image001.png@01D4865F.0A9BBA20] Super-resolution microscopy is a powerful tool for imaging structures at a lengthscale of tens of nm, but its utility for live cell imaging is limited by the time it takes to acquire the data needed for an image. For localisation microscopy the acquisition time can be cut by more than two orders of magnitude by using advanced algorithms which can analyse dense data, trading off acquisition and processing time. Information can be traded for resolution: for example, the whole dataset can by modelled as arising from blinking and bleaching fluorophores (Bayesian analysis of Blinking and Bleaching), although at a high computational cost. However, all these approaches will come with a risk of artefacts, which can mean that the image does not resemble the underlying sample. We have recently developed Harr Wavelet Kernel Analysis, a multi-timescale prefiltering technique which enables high density imaging without artefacts. The results of benchmarking with other techniques reveal that at high activation densities many analysis approaches may achieve high apparent precision (very sharp images) , but poor accuracy (the images don’t look like the sample). I will discuss the relationship between precision, accuracy and information content in super-resolution microscopy images. ~BME Faculty Host: Fang Huang~ ***Coffee and juice will be provided at West Lafayette*** -- Fang Huang Assistant Professor Weldon School of Biomedical Engineering College of Engineering, Purdue University West Lafayette, IN 47907 office: 206 S Martin Jischke Dr West Lafayette, IN 47907 Room # 2025 Phone: +1 765 494 6216

by Weinstein, Dana 27 Nov '18

27 Nov '18

Dear Birck PIs, I am seeking out information from you on any tool replacements, upgrades, or acquisitions that are most pressing to your research success in Birck. Tools that help a larger number of users or bring new capability to draw new users are of greatest interest, but please don’t hesitate to bring up anything at all that might assist or streamline research. Useful information includes: 1. What the tool/upgrade/replacement is/does 2. Why it makes a difference 3. Estimated cost 4. List of PIs who would benefit (and, even better, actively support) this investment 5. If relevant, what new capability it offers and what new users it could draw. Thanks in advance for all your input. This is vital information in providing more comprehensive service to Birck’s users and ensuring your technical success. Thanks, Dana ——————————————— Dana Weinstein Associate Professor, Electrical and Computer Engineering Associate Director of Operations, Birck Nanotechnology Center, Discovery Park Purdue University https://engineering.purdue.edu/hybridmems

Birck Thursday Lunch Seminar Series - Gaurav Vohra Thursday, November 15, 2018 12:00pm – 1:00pm BRK 1001 – Lunch Provided MEMS Gyroscopes: Modeling stress-to-offset, towards design improvements Offset stability for Gyroscopes is extremely important for MEMS devices, especially for safety critical applications. Tiny stresses resulting from tens of nanometers of deformation can violate the data sheet specification for offset. Identification and understanding of stress related offset mechanisms plays a key role in improving the performance of the next generation of MEMS sensors. This talk will cover the basics of gyroscope and highlight the difficulties of simulating stresses for vibrating sensors (like gyroscopes) and improving the stress sensitivity through design changes by an order of magnitude with experimental validation. Gaurav joined Analog Devices in 2007 after finishing his Master of Science at Marquette University. His Master's thesis work focused on design and evaluation of Piezo electric Lamb Acoustic Wave Devices. At Analog Devices,he has contributed to the design, simulation, verification and successful release of multiple automotive and consume grade MEMS gyroscope and accelerometer programs. He is currently working as a senior member of MEMS InertialS ensors design group and has 2patents issued and 7 pending.

BRK seed research grants: Fall 2018 results and reminder for Spring 2019 proposals
by Chen, Yong P 08 Nov '18

08 Nov '18

Dear colleagues: Please note the Birck Seed Grant proposals (1-page) for a spring 2019 project is due on Nov. 25, see attached call for 1-page proposals (new or updated proposals). Please email your new/updated proposal to me (yongchen(a)purdue.edu<mailto:yongchen@purdue.edu>) and cc Jaime (jjturner(a)purdue.edu) During the last cycle (for Fall 2018 projects) we received 10 excellent proposals. Thanks for Ali's support we were able to fund 2 seed projects which already are underway: "Quantum Molecular Beacons for Biomolecular Sensing" By S. Ramanathan (Materials Engineering) and J. H. Choi (Mechanical Engineering) "A Multifunctional Micro-Photonic Device for Photon Generation and Processing" By Mahdi Hosseini and Sunil Bhave (ECE) We congratulate the PIs for these seed projects and wish them the best luck in obtaining key prelim data to pursue continued funding. The other proposals received from the last cycle will be automatically considered once more during this cycle (the proposers have the optional to submit an updated version by Nov. 25) along with any new proposals received. If you already performed the project or received other funding to support we would be interested to know as well. You are still eligible to submit a different idea of course. Factors giving proposals higher priority in this program include: new research/collaboration direction clearly different from existing work, unlikely to be done otherwise yet promising for further funding; bringing people from different disciplines working together or new users to Birck or led by early-career faculty; Thanks for your continued interest and support. Best regards, Yong Yong P. Chen, PhD.

posters to represent different Birck research areas/groups
by Chen, Yong P 07 Nov '18

07 Nov '18

Dear colleagues: During the next ~2 months we will be updating the posters outside clean room (the ones showcasing the research achievements of Birck, not the educational ones about nanotechnology). Currently most of those research posters have not been updated after ~2012 and also they are mostly about single research highlights from individual groups --- we lack posters that summarize research profile of each major BRK research area (such as nanoelectronics, photonics, thermal, bionano, MEMS, manufacturing) We will be reaching out faculty representatives in each major Birck research area listed above (see also https://www.purdue.edu/discoverypark/birck/research/index.php, with corresponding faculty members listed under each area's link). The goal is to come up with 1 poster from each area summarizing the research (give highlights) of each area, plus additional posters that show case some highlights or big projects within each area in more detail. (it could be as simple as 1 slide that shows a few selected highlights each with an image from a paper with a title/reference, which should hopefully not take much time to make, such as this example from a recent slider prepared for Purdue quantum center work on quantum sensors/photonics: https://www.dropbox.com/s/a9w5s7r6y3b5jwg/1slide_quantumsensorphotonics_Pqc… ) These "area research posters" will be a convenient source to show our visitors the research activities of BRK, and will also be posted on our website too. Thank you for your cooperation on this - you will hear from your area reps and we hope to collect these posters by Jan. 1 so have them printed for new semester to showcase the updated research at Birck.
