News Item Markovic, former students win ISSCC Lewis Winner Award for Outstanding Paper

Wang_ChengChengYuanFangLiProfessor Dejan Markovic and two of his former doctoral students, Cheng C. Wang Ph.D. ’13 and Fang-Li Yuan Ph.D. ‘14, have won the 2014 Lewis Winner Award for Outstanding Paper at the International Solid-State Circuits Conference (ISSCC). The award was announced Feb. 23. 

The group conceived of, developed and tested a new design of field-programmable gate arrays (FPGAs). The design allows microprocessors to handle more complex tasks — for example, algorithm-intensive software applications such as digital signal processing, datacenter acceleration and high-speed networking — with greater flexibility while using less energy than today’s chips.

Wang and Yuan are lead authors on the paper. Markovic is principal investigator. Tsung Han-Yu Ph.D. ‘13, who has since joined Qualcomm, is a co-author.

That same research helped Wang and Yuan launch a new company. They are the first two employees of Flex Logix Technologies, a Mountain View startup headed by veteran technology entrepreneur Geoff Tate. Markovic is a consultant to the firm.

The researchers worked with UCLA Engineering’s Institute for Technology Advancement and the UCLA Office of Intellectual Property in order to develop and protect the intellectual property related to the work.

News Item Professor Chee Wei Wong is Advancing On-Chip Optics Information Transfer

Wong, Chee WeiA breakthrough by a team of researchers from UCLA, Columbia University and other institutions could lead to the more precise transfer of information in computer chips, as well as new types of optical materials for light emission and lasers. This work has been selected and featured by the Department of Energy Office of Science. 

The researchers were able to control light at tiny lengths around 500 nanometers — smaller than the light’s own wavelength — by using random photonic crystal lattice structures to counteract light diffraction. The discovery could begin a new phase in laser collimation — the science of keeping lasers precise and narrow instead of spreading out. This effect, known as Anderson localization, was first theoretically proposed in 1958 by Nobel laureate Philip Anderson, and now first observed by the UCLA-lead team of Prof. Chee Wei Wong, experimentally in on-chip optics. 

“This study allows us to validate the theory of Anderson localization in chip-scale photonics, through engineered randomness in an otherwise periodic structure,” Wong said. “This study provides a new path in controlling light propagation at the wavelength scale, that is, delivering structure arising out of randomness.”

It was published in Nature Physics on February 2, 2015, with DOI: doi:10.1038/nphys3211 : http://dx.doi.org/10.1038/nphys3211.

 

 

 


News Item Grad Student Yibo Zhang Received the 2015 SPIE Translational Research Award

Yibo Zhang, a graduate student from Professor Aydogan Ozcan’s research group, received the 2015 SPIE Translational Research Award for the paper “Pathology slide imaging using wide-field lens free microscopy.”

The paper, published in December 2014, illustrates the performance of a computational lens-free, holographic on-chip microscope that uses the transport-of-intensity equation, multi-height iterative phase retrieval, and rotational field transformations to perform wide-FOV imaging of pathology samples with comparable image quality to a traditional transmission lens-based microscope. By providing high-resolution images of large-area pathology samples with 3D digital focus adjustment, lens-free on-chip microscopy can be useful in resource-limited and point-of-care settings.

Yibo Zhang presented their paper at the Translational Research Forum on Sunday, February 8, at the 2015 SPIE Photonics West in the Moscone Center, San Francisco.SPIE_2015logo

News Item Professor Jason Cong and Dr. Yan Zhang Received the 10-Year Retrospective Most Influential Paper From ASPDAC 2015

Jason CongA paper by Professor Jason Cong and his former PhD student Dr. Yan Zhang, entitled “Thermal-Driven Multilevel Routing for 3D ICs,” was selected as the 10-Year Retrospective Most Influential Paper in the 20th Asia and South-Pacific Design Automation Conference (ASP-DAC 2015).

While most of the integrated circuits (ICs) used today are laid out on a two-dimensional surface, it is expected that future ICs will be implemented in three dimensions (3D) for achieving a much higher computing density. Design of such 3D ICs has many challenges, including heat dissipation. This paper presented a pioneering approach for a highly scalable and automated approach for interconnecting signals in a complex 3D IC with consideration of thermal management.

On the same occasion, Professor Cong also received the ASP-DAC Frequently Cited Author Award. The awards were presented at the opening ceremony of ASP-DAC 2015 on January 20, 2015 in Chiba/Tokyo, Japan.

The ASP-DAC is an annual international conference on VLSI design in Asia and the South Pacific, one of the most active regions of design and fabrication of silicon chips in the world. The conference provides opportunities for presenting the latest advancements and the future directions in technologies related to electronic design and automation.

 

 



News Item UCLA Research Found Environmental Concerns Motivate People to Save Energy

William J. KaiserProfessor William Kaiser is a co-principal investigator of the multidisciplinary research ENGAGE study in determining effective motivation in conserving energy. The research shows that messages on eliminating pollution and health-related issues are a more dominant motivator than messages on cost savings.

The sample group who received messages on how much money they could have saved had almost no change since savings for cutting back energy use would only be $4 to $6 per month, while people who received messages focused on environmental health benefits cut their energy usage by an average of eight percent. The study also showed that the environmental messages proved most effective in situations where there were children at home, where there was 19 percent reduction in energy consumption.

Electricity is generally invisible to man. Professor Kaiser’s group helped in the design and creation of smart metering systems installed in the residences of the sample group. The devices were connected to a website where the residents could see historical and real-time electricity use. It also provided the energy use of individual appliances. The residents could see the energy use as it peaked when a fridge door was opened, or the plateaus during late night work on the computer, and the power dips when people were out for the day.

The research has been a collaboration of the Institute of the Environment and Sustainability, UCLA Engineering and UCLA Anderson, experts from economics, psychology and business, and UCLA Housing and Hospitality. The research supports UCLA’s first Grand Challenge project, which aims to move Los Angeles to renewable energy and local water by 2050 while protecting biodiversity.

News Item UCLA Engineers First to Detect and Measure Individual DNA Molecules Using Smartphone Microscope

Aydogan OzcanUCLA’s California NanoSystems Institute (CNSI) researchers report the first imaging and sizing of individual DNA molecules using a lightweight, compact and cost-effective optical attachment making an ordinary smartphone into an advanced fluorescence microscope. The team led by Aydogan Ozcan, CNSI associate director and Chancellor’s Professor of electrical and bioengineering at the Henry Samueli School of Engineering and Applied Science, published their results online Dec. 10 in ACS Nano.

 The inexpensive, 3-D-printed unit uses the phone’s camera to visualize and measure the length of single-molecule DNA strands. An included attachment creates a high-contrast, dark-field imaging setup using an inexpensive external lens, thin-film interference filters, a miniature dovetail stage and a laser diode that excites the fluorescently labeled DNA molecules.

An accompanying app connects the smartphone to a UCLA server, which measures the DNA length. The molecules are labeled and stretched on disposable chips that fit in the attachment. The measurement results are seen on the phone and computers linked to the server.

“The ability to translate these and other existing microscopy and sensing techniques to field-portable, cost-effective and high-throughput instruments can make possible myriad new applications for point-of-care medicine and global health,” said Ozcan, who is also an HHMI Professor with the Howard Hughes Medical Institute.

News Item UCLA and JPL Develop Spectrometer Chip Based on CMOS Smartphone Technology for Future NASA Instruments

Mau-Chung Frank ChangUCLA faculty Frank Chang in collaboration with NASA Jet Propulsion Lab researchers Adrian Tang, Goutam Chattopadhyay, and Brian Drouin have developed an extremely low-power (less than 0.2 W) wideband spectrometer processor chip capable of detecting trace gases for future NASA instruments. The developed chip uses the same CMOS system-on-chip technology found in smartphones and tablets, allowing the spectrometer processor to be compact, and extremely energy efficient. This efficiency will enable future NASA spectrometer instruments to be flown on much smaller platforms (UAVs and cube satellites) as well as in deep space planetary science missions where power and payload size are extremely limited.

The demonstrated spectrometer chip occupies only 15 cm3 of volume and weighs less than 200 grams while its GHz-wide bandwidth makes it applicable to a wide range of Earth science, planetary science, and astrophysics applications. The single chip contains a wide range of functions including analog amplification and signal conditioning, calibration functions, analog-to-digital conversion, and signal processing to compute detected chemical spectra. UCLA graduate students Rod Kim and Li Du and visiting scholar Frank Hsiao also participated in the development of the spectrometer chip.NASA-JPL-logo
