Computational Identification Of Adaptive Mutants Using The Vert System, James Winkler, Katy Kao
Computational Identification Of Adaptive Mutants Using The Vert System, James Winkler, Katy Kao
Faculty Publications
BackgroundEvolutionary dynamics of microbial organisms can now be visualized using the Visualizing Evolution in Real Time (VERT) system, in which several isogenic strains expressing different fluorescent proteins compete during adaptive evolution and are tracked using fluorescent cell sorting to construct a population history over time. Mutations conferring enhanced growth rates can be detected by observing changes in the fluorescent population proportions.ResultsUsing data obtained from several VERT experiments, we construct a hidden Markov-derived model to detect these adaptive events in VERT experiments without external intervention beyond initial training. Analysis of annotated data revealed that the model achieves consensus with human annotation …

Faculty Publications
The proliferation of blogs and social networks presents a new set of challenges and opportunities in the way information is searched and retrieved. Even though facts still play a very important role when information is sought on a topic, opinions have become increasingly important as well. Opinions expressed in blogs and social networks are playing an important role influencing everything from the products people buy to the presidential candidate they support. Thus, there is a need for a new type of search engine which will not only retrieve facts, but will also enable the retrieval of opinions. Such a search …

Faculty Publications
The George E. Brown, Jr. Network for Earthquake Engineering Simulation coordinates a geographically distributed REU program with up to 30 students at 5 to 7 research sites each summer. Creating a sense of cohort and providing opportunities for the students to interact is challenging. The program coordinators have leveraged the NEES hub cyberinfrastructure to engage students in professional development and peer-to-peer interaction. Some experimentation with Facebook to sustain engagement with alumni is underway. Resources include a course management system (Moodle embedded in NEES hub) and a virtual world called Quake Quest. Through the course management system students post a variety …

GTI donors are high-tech business leaders with strong business ties in Silicon Valley and the Asia Pacific region. Given the current trend of engineering globalization in the global economy, particularly the trend of outsourcing Silicon Valley manufacturing, development, and design work to foreign countries, …
Impact Of Self-Efficacy On Interest And Choice In Engineering Study And Careers For Undergraduate Women Engineering Students, Patricia Backer, Rona Halualani
Impact Of Self-Efficacy On Interest And Choice In Engineering Study And Careers For Undergraduate Women Engineering Students, Patricia Backer, Rona Halualani
Faculty Publications
Self-efficacy refers to the belief in a persons’ ability to perform a specific task. Starting in middle school, girls tend to underestimate their abilities in STEM. This confidence gap among girls persists through high school into college. This gap is presumed to be partially responsible for the gender gap in engineering and other STEM fields (e.g. computer science, physics). In 2006, women only earned 19.5% of the undergraduate BS engineering degrees in the U.S. This paper investigates the motivations of women students at XXX to pursue engineering careers, including their level of self-efficacy and sources of academic support, and the …
Visualizing Evolution In Real-Time Method For Strain Engineering, Luis Reyes, James Winkler, Katy Kao
Visualizing Evolution In Real-Time Method For Strain Engineering, Luis Reyes, James Winkler, Katy Kao
Faculty Publications
The adaptive landscape for an industrially relevant phenotype is determined by the effects of the genetic determinants on the fitness of the microbial system. Identifying the underlying adaptive landscape for a particular phenotype of interest will greatly enhance our abilities to engineer more robust microbial strains. Visualizing evolution in real-time (VERT) is a recently developed method based on in vitro adaptive evolution that facilitates the identification of fitter mutants throughout the course of evolution. Combined with high-throughput genomic tools, VERT can greatly enhance the mapping of adaptive landscapes of industrially relevant phenotypes in microbial systems, thereby expanding our knowledge on …

The power spectral densities (PSD) of baseband signals in EPC Class-1 Gen-2 UHF RFID systems are shown. PSD are obtained using Matlab as the Fourier transform (via the FFT algorithm) of the autocorrelation function of random pulse sequences. The PSD of PIE, FM0 and Miller subcarrier for M=2, 4 and 8 are shown for both unipolar (for 100% ASK or OOK modulation) and polar (PSK modulation) waveforms.
Novel On-Demand Droplet Generation For Selective Fluid Sample Extraction, Melinda Simon, Jeffrey Fisher, Melinda Simon, Abraham Lee
Novel On-Demand Droplet Generation For Selective Fluid Sample Extraction, Melinda Simon, Jeffrey Fisher, Melinda Simon, Abraham Lee
Faculty Publications
A novel microfluidic device enabling selective generation of droplets and encapsulation of targets is presented. Unlike conventional methods, the presented mechanism generates droplets with unique selectivity by utilizing a K-junction design. The K-junction is a modified version of the classic T-junction with an added leg that serves as the exit channel for waste. The dispersed phase fluid enters from one diagonal of the K and exits the other diagonal while the continuous phase travels in the straight leg of the K. The intersection forms an interface that allows the dispersed phase to be controllably injected through actuation of an elastomer …
A Laplace Pressure Based Microfluidic Trap For Passive Droplet Trapping And Controlled Release, Melinda Simon, Robert Lin, Jeffrey Fisher, Abraham Lee
A Laplace Pressure Based Microfluidic Trap For Passive Droplet Trapping And Controlled Release, Melinda Simon, Robert Lin, Jeffrey Fisher, Abraham Lee
Faculty Publications
Here, we present a microfluidic droplet trap that takes advantage of the net Laplace pressure force generated when a droplet is differentially constricted. Mathematical simulations were first used to understand the working range of the component; followed by finite element modeling using the CFDsoftware package to further characterize the behavior of the system. Controlled release of the trapped droplets is also demonstrated through both a mechanical method and a chemical method that manipulates the total pressure exerted on the trapped droplet. The unique design of this trapping device also provides the capability for selection of a single dropletfrom a train, …
Design Optimization Of Transistors Used For Neural Recording, E J. Basham, David W. Parent
Design Optimization Of Transistors Used For Neural Recording, E J. Basham, David W. Parent
Faculty Publications
Neurons cultured directly over open-gate field-effect transistors result in a hybrid device, the neuron-FET. Neuron-FET amplifier circuits reported in the literature employ the neuron-FET transducer as a current-mode device in conjunction with a transimpedance amplifier. In this configuration, the transducer does not provide any signal gain, and characterization of the transducer out of the amplification circuit is required. Furthermore, the circuit requires a complex biasing scheme that must be retuned to compensate for drift. Here we present an alternative strategy based on the design approach to optimize a single-stage common-source amplifier design. The design approach facilitates in circuit characterization of …

Online social networking is deeply interleaved in today's lifestyle. People come together and build communities to share thoughts, offer suggestions, exchange information, ideas, and opinions. Moreover, social networks often serve as platforms for information dissemination and product placement or promotion through viral marketing. The success rate in this type of marketing could be increased by targeting specific individuals, called 'influential users', having the largest possible reach within an online community. In this paper, we present a method aiming at identifying the influential users within an online social networking application. We introduce ProfileRank, a metric that uses popularity and activity characteristics …
Defining, Teaching, And Assessing Engineering Design Skills, Nikos J. Mourtos
Defining, Teaching, And Assessing Engineering Design Skills, Nikos J. Mourtos
Faculty Publications
The paper discusses a systematic approach for defining, teaching, and assessing engineering design skills. Although the examples presented in the paper are from the field of aerospace engineering, the principles apply to engineering design in general. What makes the teaching of engineering design particularly challenging is that the necessary skills and attributes are both technical and non-technical and come from the cognitive as well as the affective domains. Each set of skills requires a different approach to teach and assess. Implementing a variety of approaches for a number of years at SJSU has shown that it is just as necessary …
