Promoting Carpooling with Distributed Schedule Coordination and Incentive Alignment of Contacts (2015)

Carpooling is recognized as a viable alternative by city managers to reduce traffic demand and consequent congestion and pollution on city roads. Members of a carpool face the daily challenge of deciding whether to go alone or with some or all members of their carpool, and further, to take their own vehicle or ride with others. These decisions may seem trivial in isolation but if not taken judiciously, over time, may disrupt the carpool. In this paper, we have designed a system which models daily carpool scheduling as a repeated stochastic game played among willing carpoolers which allows for individual choices and promotes carpooling as an equilibrium outcome through equitable payoff distribution using social credits. We empirically show the efficacy of our system through simulation and also discuss how game-theoretic design inherently helps to deploy the system as a mobile application.
Understanding of the endurance failure in scaled HfO<inf>2</inf>-based 1T1R RRAM through vacancy mobility degradation (2012)

Bipolar switching transition metal-oxide (TMO) RRAM devices are intensively studied as possible non-volatile memory for 1x nm node. HfO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> based stacks with excellent operation, good endurance and retention have been proposed [1, 2, 3], with demonstrated scalability down to <;10nm [3]. However, characterization of the reliability failure modes and understanding of the degradation mechanism is urgently needed, especially in the low operation current range relevant for practical application of RRAM devices. Although retention and endurance models in different TMO have been proposed [4, 5, 6], an in-depth understanding of endurance is still lacking for scaled HfO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> RRAM in low current operation.
Temporal learning and sequence modeling for a job recommender system (2016)

We present our solution to the job recommendation task for RecSys Challenge 2016. The main contribution of our work is to combine temporal learning with sequence modeling to capture complex user-item activity patterns to improve job recommendations. First, we propose a time-based ranking model applied to historical observations and a hybrid matrix factorization over time re-weighted interactions. Second, we exploit sequence properties in user-items activities and develop a RNN-based recommendation model. Our solution achieved 5th place in the challenge among more than 100 participants. Notably, the strong performance of our RNN approach shows a promising new direction in employing sequence modeling for recommendation systems.

Purpose and Polarity of Citation: Towards NLP-based Bibliometrics (2013)

Bibliometric measures are commonly used to estimate the popularity and the impact of published research. Existing bibliometric measures provide “quantitative ” indicators of how good a published paper is. This does not necessarily reflect the “quality ” of the work presented in the paper. For example, when h-index is computed for a researcher, all incoming citations are treated equally, ignoring the fact that some of these citations might be negative. In this paper, we propose using NLP to add a “qualitative ” aspect to biblometrics. We analyze the text that accompanies citations in scientific articles (which we term citation context). We propose supervised methods for identifying citation text and analyzing it to determine the purpose (i.e. author intention) and the polarity (i.e. author sentiment) of citation. 1

Effects of Nanofillers on the Thermo-Mechanical Properties and Chemical Resistivity of Epoxy Nanocomposites (2014)

MWCNTs was synthesized using Ni-Cr/MgO by CVD method and were purified. The purified MWCNT was used as a filler material for the fabrication of epoxy nanocomposites. The epoxy nanocomposites with different amount (wt% = 0.5, 1.0, 2.0, 3.0, 4.0 and 5.0) of nanofillers (CB, SiO2 and MWCNTs) were prepared by casting method. The effects of nanofillers on the properties of neat epoxy matrix were well studied. The thermal properties of nanocomposites were studied using DSC, TGA and flame retardant, and also the mechanical properties such as tensile strength, flexural strength, compressive strength, impact strength, determination of hardness and chemical resistance were studied extensively. Based on the experiment's results, 2 wt% MWCNTs loading in epoxy resin showed the highest improvement in tensile strength, as compared to neat epoxy and to other epoxy systems (CB/epoxy, SiO2/epoxy). Improvements in tensile strength, glass transition temperature and decomposition temperature were observed by the addition of MWCNTs. The mechanical properties of the epoxy nanocomposites were improved due to the interfacial bonding between the MWCNTs and epoxy resin. Strain hardening behavior was higher for MWCNT/epoxy nanocomposites compared with CB/epoxy and SiO2/epoxy nanocomposites. The investigation of thermal and mechanical properties reveals that the incorporation of MWCNTs into the epoxy nanocomposites increases its thermal stability to a great extent. Discrete increase of glass transition temperature of nanocomposites is linearly dependent on MWCNTs content. Due to strong interfacial bonding between MWCNTs and epoxy resin, the chemical resistivity of MWCNT/epoxy nanocomposites is superior to neat epoxy and other epoxy systems.
Pregelix (2014)

There is a growing need for distributed graph processing systems that are capable of gracefully scaling to very large graph datasets. Unfortunately, this challenge has not been easily met due to the intense memory pressure imposed by process-centric, message passing designs that many graph processing systems follow. Pregelix is a new open source distributed graph processing system that is based on an iterative dataflow design that is better tuned to handle both in-memory and out-of-core workloads. As such, Pregelix offers improved performance characteristics and scaling properties over current open source systems (e.g., we have seen up to 15X speedup compared to Apache Giraph and up to 35X speedup compared to distributed GraphLab), and more effective use of available machine resources to support Big(ger) Graph Analytics.
Applying linked data principles to represent patient's electronic health records at Mayo clinic (2012)

The Linked Open Data (LOD) community project at the World Wide Web Consortium (W3C) is publishing various open data sets as Resource Description Framework (RDF) on the Web and extending it by setting RDF links between data items from different data sources containing information about genes, proteins, pathways, diseases, and drugs. While this presents a very powerful platform for federated querying and heterogeneous data integration, its true potential can only be realized when combining such information with "real patient" data from electronic health records. In this paper, we report our early experiences in applying Linked Data principles and technologies for representing patient data from electronic health records (EHRs) at Mayo Clinic in RDF. In particular, we demonstrate a proof-of-concept case study leveraging publicly available data from the Linked Open Drug Data cloud to federated querying for type 2 diabetes patients. Our study highlights several challenges and opportunities in using Semantic Web tools and technologies within a healthcare setting for enabling clinical and translational research.
An integrated debugging environment for FPGA computing platforms (2008)

Large-scale, direct-mapped FPGA computing systems are traditionally very difficult to debug due to the high level of parallelism and limited access to internal signal values. In our approach to mitigate this problem, the concepts of variables and process control are brought into the FPGA hardware domain. Declarations made in the design environment are translated into logic inserted automatically into the hardware implementation. Variables provide full read/write access to hardware signals during runtime, complete with same-cycle, dynamically definable assertion checking. System data is cached via attached DRAM, providing deep variable history and the ability to ldquorewindrdquo system state. Process execution can also be controlled by the user manually or through the declaration of breakpoints. All debugging controls are available via a remote graphical user interface, which also supports back-annotation in the input design for improved data visibility and comprehension. Empirical examples have shown the logic overhead for the above functionality to be approximately 66 slices per 16-bit variable with full assertion checking on a Virtex-II Pro device, plus the fixed requirements of the debug controller and memory interface.
Wet Spheronization by Rotary Processing—A Multistage Single‐Pot Process for Producing Spheroids (2004)

Spheronization is an agglomerative size enlargement process for producing spherical agglomerates that have many technological and therapeutical advantages. Rotary processing is an efficient multistage, single-pot spheroid production method. The rotary processor can be used for spheroid production, drying as well as coating. In the course of spheroid production, centrifugal, fluidizing, and gravitational forces act upon the product from different directions and collectively contribute to the spheroid formation process during rotary processing. The outcome of the process depends on the complex interactions between the equipment, formulation, and process variables.
Design and synthesis of the pseudo‐EF hand in calbindin D<sub>9K</sub>: Effect of amino acid substitutions in the α‐helical regions (1991)

A series of 37-residue analogues of the pseudo-EF hand in bovine calbindin D9K has been synthesized by the solid phase method. In the presence of calcium an alpha-helical induction of up to 44% was observed for the peptide with the native sequence with a Kd for calcium binding of 0.35 mM. A number of amino acid substitutions have been carried out to study the packing of the two alpha-helices based on the crystal structure of the entire protein. Three strategies were employed: (1) replacement of the Leu residues, which in the crystal structure do not contribute to the hydrophobic interaction between the two helices, by Gln or Ala in order to control the orientation of the helix packing, (2) stabilization of the individual helix by introducing a Glu-...Lys+ salt bridge or by changing the N-terminal charge to compensate for the helix dipole moment, and (3) introduction of a disulfide bond between the two helices to help the packing of the helices. The mutants with the substitution of (Leu-30, Leu-32) to (Gln-30, Gln-32), (Gln-30, Ala-32), and (Ala-30,Ala-32) designed based on the strategy 1 do not show any affinity for calcium and have low alpha-helicity. The Leu-30 to Lys-30 mutant designed to form a salt bridge between the side chains of Glu-26 and Lys-30 has an apparent Kd for calcium of 6.8 mM. Kd of the N-terminal acetylated and succinylated mutants are 0.41 and 0.45 mM, respectively, and no increase in the alpha-helix content relative to that of the natural sequence peptide is observed. The disulfide containing mutants, namely Tyr-13, Leu-31 to Cys-13, Cys-31 and Tyr-13, Leu-31 to Cys-13, hCys-31, show apparent Kd values of 0.93 and 2.1 mM, respectively. The former mutant shows the highest alpha-helix content among the peptides studied in the presence and absence of calcium. While it is difficult to construct an isolated and rigid helix-loop-helix motif with peptides of this size, introduction of a disulfide bond proved to be effective for this purpose.
Femtosecond surface emitting lasers (2011)

Diode-pumped solid state lasers, long dominant in many high power applications, now face a challenge from opticallypumped semiconductor lasers, which add spectral versatility to the good beam quality and potential for power-scaling that are characteristic of optically-pumped disc lasers. The vertical-external-cavity surface-emitting semiconductor laser, or VECSEL, readily exhibits passive mode-locking with the inclusion of a semiconductor saturable absorber mirror (SESAM) in the external cavity. These devices most often emit picosecond pulses, recruiting only a small fraction of the available gain bandwidth of the quantum wells. If the dispersive and filtering effects of the multilayer gain and saturable absorber structures are well-controlled, however, it is possible to observe clean sub-picosecond pulses of duration down to 100fs and below. The presentation will describe SESAM-mode-locked VECSELs based on compressively strained InGaAs/GaAs quantum wells that generate trains of near-transform-limited femtosecond pulses at wavelengths around 1 μm with average power of 30 - 300 mW. The nonlinear optical response of the quantum well SESAM in this regime is investigated using a numerical model in which the resonantly excited carriers are coupled by scattering to states outside the laser bandwidth.
Characterization of a novel β-glucosidase-like activity from a soil metagenome (2009)

We report the cloning of a novel beta-glucosidase-like gene by function-based screening of a metagenomic library from uncultured soil microorganisms. The gene was named bgllC and has an open reading frame of 1,443 base pairs. It encodes a 481 amino acid polypeptide with a predicted molecular mass of about 57.8 kDa. The deduced amino acid sequence did not show any homology with known beta-glucosidases. The putative beta-glucosidase gene was subcloned into the pETBlue-2 vector and overexpressed in E. coli Tuner (DE3) pLacI; the recombinant protein was purified to homogeneity. Functional characterization with a high performance liquid chromatography method demonstrated that the recombinant BgllC protein hydrolyzed D-glucosyl-beta-(l-4)-D-glucose to glucose. The maximum activity for BgllC protein occurred at pH 8.0 and 42 degrees C using p-nitrophenyl-beta-D-glucoside as the substrate. A CaCl(2) concentration of 1 mM was required for optimal activity. The putative beta-glucosidase had an apparent K(m) value of 0.19 mM, a V(max) value of 4.75 U/mg and a k (cat) value of 316.7/min under the optimal reaction conditions. The biochemical characterization of BgllC has enlarged our understanding of the novel enzymes that can be isolated from the soil metagenome.
Structural Phase Stability Control of Monolayer MoTe<sub>2</sub> with Adsorbed Atoms and Molecules (2015)

We study the adsorption of some common atoms and molecules onto monolayer MoTe2 and the potential for adsorption to induce a structural phase change between the semiconducting 2H-based and metallic 1T′-based crystal structures of the monolayer. Using density functional theory with spin–orbit and van der Waals energy contributions, we determined energetically favorable adsorption positions and orientations on the two crystalline phases of monolayer MoTe2. We then obtained the formation energies for these adsorption reactions and found that atomic adsorption generally favors 1T′ metallic phases while molecular adsorption favors semiconducting 2H phases. The phase sensitivity of this material is due to a relatively small energy difference, approximately 31 meV per MoTe2 formula unit. We further find that the monolayer alloy MoxW1–xTe2 can exhibit some degree of molecular selectivity in phase changes, potentially providing the basis for molecular sensing applications.
The global regulator H-NS acts directly on the transpososome to promote Tn10 transposition (2005)

The histone-like nucleoid structuring (H-NS) protein is a global transcriptional regulator that is known to regulate stress response pathways and virulence genes in bacteria. It has also been implicated in the regulation of bacterial transposition systems, including Tn10. We demonstrate here that H-NS promotes Tn10 transposition by binding directly to the transposition complex (or transpososome). We present evidence that, upon binding, H-NS induces the unfolding of the Tn10 transpososome and helps to maintain the transpososome in an unfolded state. This ensures that intermolecular (as opposed to self-destructive intramolecular) transposition events are favored. We present evidence that H-NS binding to the flanking donor DNA of the transpososome is the initiating event in the unfolding process. We propose that by recruiting H-NS as a modulator of transposition, Tn10 has evolved a means of sensing changes in host physiology, as the amount of H-NS in the cell, as well its activity, are responsive to changes in environmental conditions. Sensing of environmental changes through H-NS would allow transposition to occur when it is most opportune for both the transposon and the host.
Mechanisms of Dietary Protein-Induced Changes in Calcium Absorption Efficiency (2013)

Quantitative conditions are derived which a basis set must satisfy if it is to be used for describing radiationless decay. The derivation is valid for both internal conversion and intersystem crossing.
Schistosomiasis vaccine development: progress and prospects (1998)

The undisputed, worldwide success of chemotherapy notwithstanding, schistosomiasis continues to defy control efforts in as much rapid reinfection demands repeated treatment, sometimes as often as once a year. There is thus a need for a complementary tool with effect for the longer term, notably a vaccine. International efforts in this direction have been ongoing for several decades but, until the recombinant DNA techniques were introduced, antigen production remained an unsurmountable bottleneck. Although animal experiments have been highly productive and are still much needed, they probably do not reflect the human situation adequately and real progress can not be expected until more is known about human immune responses to schistosome infection. It is well-known that irradiated cercariae consistently produce high levels of protection in experimental animals but, for various reasons, this proof of principle cannot be directly exploited. Research has instead been focussed on the identification and testing of specific schistosome antigens. This work has been quite successful and is already at the stage where clinical trials are called for. Preliminary results from coordinated in vitro laboratory and field epidemiological studies regarding the protective potential of several antigens support the initiation of such trials. A series of meetings, organized earlier this year in Cairo, Egypt, reviewed recent progress, selecteded suitable vaccine candidates and made firm recommendations for future action including pledging support for large-scale production according to good manufacturing practice (GMP) and Phase I trials. Scientists at the American Centers for Disease Control and Prevention (CDC) have drawn up a detailed research plan. The major financial support will come from USAID, Cairo, which has established a scientific advisory group of Egyptian scientists and representatives from current and previous international donors such as WHO, NIAID, the European Union and the Edna McConnell Clark Foundation.
Colonic retinoblastoma protein and proliferation in cancer and non‐cancer patients<sup>#</sup> (1997)

Both suppressor oncogene and proliferative activity are believed to indicate colon cancer risk. The retinoblastoma (Rb) gene is a suppressor oncogene affecting cell differentiation. Retinoblastoma gene inactivation is associated with tumour development. However, the relation of the Rb protein to cell proliferation and colon tumour formation is unknown. Retinoblastoma protein quantity was correlated with proliferative activity in flat, unaffected mucosa specimens from 36 cancer patients, 21 non-cancer control subjects and in 29 tumour tissue samples from cancer patients. Nuclear Rb protein was measured by using automated CAS-200 image analysis of monoclonal antibody labelled frozen sections from fresh, surgically removed tissue. All colon cells within 15 whole crypts were imaged. Proliferative activity was also measured by using analysis with Ki-67 monoclonal antibody. Retinoblastoma protein content correlated directly with proliferative activity in flat mucosa of non-cancer control subjects (r = 0.63; P < 0.001; n = 21). A significant correlation was also found in flat mucosa specimens of non-metastatic (Duke's stages A and B) cancer patients (r = 0.52; P < 0.01; n = 22). However, Rb protein did not correlate with proliferation in flat mucosa from metastatic (Duke's stages C and D) cancer patients (r = 0.03; NS; n = 14) or in cancer tissue (r = 0.068; NS; n = 29). Mucosal Rb protein in the colon normally increases as proliferation increases. Dissociation between Rb protein and colon proliferation may occur in flat mucosa in patients with a higher risk of metastatic tumour growth. Future studies comparing Rb protein quantity and proliferative activity may help identify high-risk colon cancer patients.
Experimental evaluation of the gas recovery factor of methane hydrate in sandy sediment (2014)

Recovery factor of methane hydrate in sandy sediments can be enhanced using the sensible heat of the hydrate-bearing sediments and the latent heat of ice formation by applying deep depressurization.
Debugging Distributed Systems (2016)

Distributed systems pose unique challenges for software developers. Reasoning about concurrent activities of system nodes and even understanding the system’s communication topology can be difficult. A standard approach to gaining insight into system activity is to analyze system logs. Unfortunately, this can be a tedious and complex process. This article looks at several key features and debugging challenges that differentiate distributed systems from other kinds of software. The article presents several promising tools and ongoing research to help resolve these challenges.
