Deep Collaborative Filtering via Marginalized Denoising Auto-encoder (2015)

Collaborative filtering (CF) has been widely employed within recommender systems to solve many real-world problems. Learning effective latent factors plays the most important role in collaborative filtering. Traditional CF methods based upon matrix factorization techniques learn the latent factors from the user-item ratings and suffer from the cold start problem as well as the sparsity problem. Some improved CF methods enrich the priors on the latent factors by incorporating side information as regularization. However, the learned latent factors may not be very effective due to the sparse nature of the ratings and the side information. To tackle this problem, we learn effective latent representations via deep learning. Deep learning models have emerged as very appealing in learning effective representations in many applications. In particular, we propose a general deep architecture for CF by integrating matrix factorization with deep feature learning. We provide a natural instantiations of our architecture by combining probabilistic matrix factorization with marginalized denoising stacked auto-encoders. The combined framework leads to a parsimonious fit over the latent features as indicated by its improved performance in comparison to prior state-of-art models over four large datasets for the tasks of movie/book recommendation and response prediction.
This paper is published as part of a PCCP Themed Issue on: Physical Chemistry of Ionic Liquids (2010)

Received 13th October 2009, Accepted 1st March 2010First published as an Advance Article on the web 7th April 2010DOI: 10.1039/b921368fWe present the ﬁrst kinetic study of quantised double layer charging of monolayer-protectedgold clusters in an ionic liquid. Cyclic voltammetry and electrochemical impedance measurementsreveal that kinetic control is involved in the quantised cluster charging in these room temperaturemelts. The level of kinetic control varies up to one order of magnitude depending on ionic liquidcomposition, which may have implications for the development of future nanoelectronic devices.By studying the quantised charging process in the chemically relevant permutations of two anionsand two cations, we ﬁnd strong indications that the ionic liquid behaviour is not a linearcombination of its composing ions’ properties, but is dominated by speciﬁc interactions. Basedon a Walden plot analysis, we hypothesise that the chemical availability of ions is diﬀerent in thevarious liquids, and explains the diﬀerences in monolayer-protected gold cluster (MPC)charging rates.
Principles of Ray Tracing Aberrometry (2000)

<title>Graph-based table recognition system</title> (1996)

This paper proposes a bottom-up method for recognizing tables within a document. This method is based on the paradigm of graph-rewriting. First, the document image is transformed into a layout graph whose nodes and edges represent document entities and their interrelations respectively. This graph is subsequently rewritten using a set of rules designed based on a priori document knowledge and general formatting conventions. The resulting graph provides a logical view of the document content. It can be parsed to provide general format analysis information.
An APS-C format 14b digital CMOS image sensor with a dynamic response pixel (2011)

CMOS image sensors are now used in a variety of camera applications, such as mobile phones, camcorders, and digital still cameras (DSCs). In particular, most digital single-lens reflex (DSLR) cameras and so called “mirror-less” cameras that require a large-format sensor also employ CMOS image sensors due to their lower power consumption and higher readout speed compared to their CCD counterparts.
Automatic Evaluation of Progression Angle and Fetal Head Station through Intrapartum Echographic Monitoring (2013)

Labor progression is routinely assessed through transvaginal digital inspections, meaning that the clinical decisions taken during the most delicate phase of pregnancy are subjective and scarcely supported by technological devices. In response to such inadequacies, we combined intrapartum echographic acquisitions with advanced tracking algorithms in a new method for noninvasive, quantitative, and automatic monitoring of labor. Aim of this work is the preliminary clinical validation and accuracy evaluation of our automatic algorithm in assessing progression angle (PA) and fetal head station (FHS). A cohort of 10 parturients underwent conventional labor management, with additional translabial echographic examinations after each uterine contraction. PA and FHS were evaluated by our automatic algorithm on the acquired images. Additionally, an experienced clinical sonographer, blinded regarding the algorithm results, quantified on the same acquisitions of the two parameters through manual contouring, which were considered as the standard reference in the evaluation of automatic algorithm and routine method accuracies. The automatic algorithm (mean error ± 2SD) provided a global accuracy of 0.9 ± 4.0 mm for FHS and 4° ± 9° for PA, which is far above the diagnostic ability shown by the routine method, and therefore it resulted in a reliable method for earlier identification of abnormal labor patterns in support of clinical decisions.
Microdialysis coupled with an embedded systems controller and CMOS image sensor (2009)

Continuous monitoring of specific metabolite and drug levels within a patient's blood can contribute to shorter hospital stays and more successful treatment of both chronic and acute diseases. Intravenous microdialysis is an attractive technology for continuous venous blood sampling that can be used to manage tight glucose control and to sample a large variety of molecules from human blood. In combination with lab-on-a-chip architectures, microdialysis could provide continuous monitoring of important diagnostic and therapeutic substances. Unfortunately, microdialysis is inherently variable and non-transparent, i.e., errors in sampling cannot be detected and corrected in real-time. A portable microdialysis system is presented that gauges membrane diffusive capacity by using a fluorescent tracer, providing a method to track the intrinsic variability. An embedded systems controller and CMOS image sensor is used to measure and wirelessly communicate fluorescent tracer levels. The controller has the capability to generate alarms when probe performance deteriorates, making microdialysis both more accurate and robust for clinical use. The potential to integrate a microparticle-based, turbidimetric vancomycin immunoassay with microdialysis is also demonstrated by using a CMOS image sensor to detect changes in turbidity.
Variation in the Quantitation of Prostate-specific Antigen in Reference Material: Differences in Commercial Immunoassays, (1998)

Prostate-specific antigen (PSA) is a widely used biochemical marker for prostate cancer (1). PSA, a serine protease, forms complexes with serine protease inhibitors such as α2-macroglobulin and α1-antichymotrypsin (ACT) (2). The major immunoreactive forms of serum PSA are PSA-ACT complex and free PSA. PSA complexed to α2-macroglobulin is not measured by current immunoassays (3). Because the proportion of PSA complexed to ACT is higher in men with prostate cancer than in men with benign prostatic hyperplasia (BPH) (3)(4), the use of a ratio of free-to-total PSA may improve discrimination between men with BPH and prostate cancer (5)(6).

Results obtained with different PSA immunoassays are not interchangeable (7)(8)(9)(10). The variation among immunoassays reflects, in large part, the specificity of different PSA antibodies (7). To a lesser extent, the composition of the calibrator, the PSA values assigned to the calibrator, the test diluent, and the physical design of the immunoassays contribute to intermethod differences (6)(7). Assays using a monoclonal-monoclonal sandwich format yield, in general, an equimolar response to free and ACT-complexed PSA, whereas monoclonal-polyclonal formats tend to yield higher values for samples containing greater proportions of free PSA (8). We have recently described the Bayer Immuno 1TM PSA Assay (Bayer Corporation), which uses a monoclonal-polyclonal antibody format that yields an equimolar response to varying proportions of free and complexed PSA (11). This has now been found to be a result of the unique binding properties of the monoclonal antibody used for the capture of PSA (manuscript in submission).

Proficiency testing among clinical laboratories has indicated large intermethod variability in the quantitation of total PSA (12). The aim of this study was to determine the magnitude and cause of this intermethod variation. Here we report our multi-site analysis of …
A physical principle of gait generation and its stabilization derived from mechanism of fixed point (2006)

Passive walker with knees can walk down shallow slope in a natural gait and can exhibit a stable limit cycle. Though the passive walker is mechanically simple, it is a sort of hybrid system that combines the continuous dynamics of leg-swing motion and the discrete event of leg-exchange. In this paper, we focus on the mechanism of fixed point. We demonstrate a physical principle of gait generation and its stabilization derived from the mechanism of fixed point. Based on the principle, we made a simple improvement on passive walker with knees. The passive walker could have high stability, and could walk on treadmill for 4010 steps
Band structure and transport studies of copper selenide: An efficient thermoelectric material (2014)

We report the band structure calculations for high temperature cubic phase of copper selenide (Cu2Se) employing Hartree-Fock approximation using density functional theory within the generalized gradient approximation. These calculations were further extended to theoretically estimate the electrical transport coefficients of Cu2Se employing Boltzmann transport theory, which show a reasonable agreement with the corresponding experimentally measured values. The calculated transport coefficients are discussed in terms of the thermoelectric (TE) performance of this material, which suggests that Cu2Se can be a potential p-type TE material with an optimum TE performance at a carrier concentration of ∼4−6×1021cm−3.
Anomalously Low Surface Area and Density in the Silica—Alumina Gel System (1989)

A range of composition/processing conditions that yield xerogel surface areas 2 orders of magnitude lower than expected along with low skeletal densities has been discovered. For xerogel compositions in the vicinity of 50 wt% Al 2 O 3 , surface areas are 1 to 5 m 2 /g and skeletal densities are 2.1 to 2.2 g/cm 3 , as compared to the expected values of ∼300 m 2 /g and ∼2.6 g / cm 3 , respectively. This behavior is observed over a wide range of heat treatment temperatures (373 to 1073 K) and appears to be the result of closed porosity which evolves during gel drying.
Optical Interconnects in the Data Center (2010)

Optical interconnects in large-scale systems offer the possibility of new system topologies, with many multi-core processors and memories integrated together and densely co packaged. This opens up new possibilities in large-scale installations like data centers, supporting both commercial and scientific applications. A first step is to explore the optical and electrical circuits and devices required to create optical links, but many interesting research questions remain about how to construct large-scale systems that employ those links.
Selective Detection of Airborne Asbestos Fibers Using Protein-Based Fluorescent Probes (2009)

Fluorescence microscopy (FM) is one of the most important analytical tools in modern life sciences, sufficiently sensitive to allow observation of single molecules. Here we describe the first application of the FM technique for the detection of inorganic environmental pollutants-airborne asbestos fibers that can cause asbestosis, mesothelioma, and lung cancer. In order to assess FM capabilities for detecting and counting asbestos fibers, we screened E. coli lysate for proteins that bind to amphibole asbestos. In combination with the previously discovered E. coli protein DksA (Kuroda et al., Biotechnol. Bioeng. 2008, 99, 285-289) that can specifically bind to chrysotile, the newly identified GatZ protein was used for selective and highly sensitive detection of two different asbestos types. Our novel FM-based method overcomes a number of limitations of the commonly used phase-contrast microscopy (PCM) method, offering a convenient alternative to PCM for airborne asbestos monitoring.
Frame rate up-conversion assisted with camera auto exposure information (2012)

Frame rate up conversion (FRC) is the process of converting between different frame rates for targeted display formats. Besides scanning format applications for large displays, FRC can be used to increase the frame rate of video at the receiver end for video telephony, video streaming or playback applications for mobile platforms where bandwidth savings are crucial. Many algorithms have been proposed for decoder/receiver side FRC. However, most of them are from video encoding/decoding point of view. We systematically studied the strategies of utilizing the camera 3A (auto exposure, auto white balance and auto focus) information to assist FRC process, while in this paper we focus on the technique using camera exposure information to assist the decoder FRC. In the proposed strategy the exposure information as well as other camera 3A related information is packetized as the meta data which is attached to the corresponding frame and transmitted together with the main video bit stream to the decoder side for FRC assistance. The meta data contains information such as zooming, auto focus, AE (auto exposure), AWB (auto white balance) statistics, scene change detection, global motion detected from motion sensors. The proposed meta data consists of camera specific information which is different than just sending motion vectors or mode information to aid FRC process. Compared to traditional FRC approaches used in mobile platforms, the proposed approach is a low-complexity, low-power solution which is crucial in resource constrained environments such as mobile platforms.
Failure-independent path-protecting p-cycles: efficient and simple fully preconnected optical-path protection (2005)

We propose a new technique for optical-network protection called failure-independent path-protecting (FIPP) p-cycles. The method is based on an extension of p-cycle concepts to retain the property of full preconnection of protection paths, while adding the property of end-to-end failure-independent path-protection switching against either span or node failures. An issue with applying the popular method of shared-backup path protection (SBPP) to an optical network is that spare channels for the backup path must be cross connected on the fly upon failure. It takes time and signaling to make the required cross connections, but more importantly, until all connections are made, it is not actually known if the backup optical path will have adequate transmission integrity. Thus, speed and optical-path integrity are important reasons to try to have backup paths fully preconnected before failure. With fully preconnected protection, not only can very fast restoration be attained, but the optical-path engineering can also be assured prior to failure. Regular p-cycles are fully preconnected, but are not end-to-end path-protecting structures. SBPP is capacity efficient and failure independent-failures only need to be detected at the end nodes and the end nodes activate and switch over to one predefined backup route for each working path-but the backup paths are not preconnected. FIPP p-cycles support the same failure-independent end-node-activated switching of SBPP, but with the fully preconnected protection-path property of p-cycles. As a fully preconnected and path-oriented scheme, FIPP p-cycles are, therefore, potentially more attractive for optical networks than SBPP. Results confirm that FIPP p-cycle network designs will exhibit capacity efficiency that is characteristic of path-oriented schemes and may be as capacity efficient as SBPP, but more conclusive comparisons on larger scale networks await further study.

An experimentally validated panel of subfamily‐specific oligonucleotide primers (V<sub>α</sub>1‐w29/V<sub>β</sub>1‐w24) for the study of human T cell receptor variable V gene segment usage by polymerase chain reaction (1992)

Abstract We report here the characterization of a series of T cell receptor (TcR) V α or V β subfamily‐specific oligonucleotide primers. Criteria that have guided the design of each oligonucleotide include appropriate thermodynamic parameters as well as differential base‐pairing scores with related and unrelated target sequences. The specificity of the oligonucleotides for each V α or V β subfamily was tested by polymerase chain reaction (PCR) on both a series of TcR encoding plasmid DNA and clonal T cell populations. Unexpected cross‐reactivities were observed with plasmid cDNA sequences corresponding to unrelated subfamily gene segments. This led to the synthesis of additional series of oligonucleotides to obtain a relevant panel. A series of V α 1‐w29/V β 1‐w24 TcR subfamily‐specific oligonucleotides was eventually selected which generates little, if any, cross‐reactivity. The use of C α or C β primers for the amplification of internal positive control templates ( i.e. C β for the V α series and C α for the V β series) has been tested in PCR performed with cDNA derived from peripheral blood lymphocytes; it was shown not to alter the amplification of the V subfamily‐specific DNA fragments. This panel of oligonucleotides will be helpful in the study of TcR V gene segment usage and, thus, may lead to a better characterization of T cell responses in physiological and pathological situations.
Eliminating undetected interest looping in content-centric networks (2015)

It has been shown that Interest loops can go undetected in NDN (named data networking) and CCNx (content-centric networking) when Interests are aggregated. To solve this problem, we introduce CCN-ELF, a simple variation of the way in which CCNx and NDN work based on a new type of forwarding information base (FIB) that stores distance information about name prefixes for neighbors of a content router that can serve as next hops, rather than just a ranked list of those next hops. CCN-ELF uses a loop-free forwarding algorithm based on the information available in the new FIBs that allows Interests to be forwarded and aggregated, without the risk of undetected Interest loops and without requiring any changes to the packet formats used in NDN and CCNx.
An Adjustable Self-Equalizing Photo Detector (2015)

When DRM Meets Restricted Multicast: A Content Encryption Key Scheme for Multicast Encryption and DRM (2007)

In many applications it is desired to save the content received from restricted broadcast or multicast to local files for subsequent replays. The locally saved files should be protected by a Digital Rights Management (DRM) system to prevent unauthorized usage. It is a great challenge to combine DRM with restricted broadcast or multicast since they are designed for different applications. In this paper, we first present two straight- forward solutions and discuss their drawbacks. We then present a novel content encryption key scheme for restricted broadcast and multicast that facilitates subsequent DRM protection for the saved content. It enables direct saving of encrypted content to local files and easy generation and management of decryption keys for replays of saved files. Only a single key needs to be delivered to a client in a license. Security of the proposed key scheme is analyzed, and comparison of the three methods in also discussed in this paper.
Integral fill yarn insertion and beatup method using inflatable membrane (1993)

An apparatus and method for integral fill yarn insertion and beatup are disclosed. A modified rapier contains a channel for holding fill yarn. The channel is covered with a flexible and inflatable boot, and an inflating apparatus for this boot is also attached. Fill yarn is inserted into the channel, and the rapier is extended into a shed formed by warp yarn. Next, the rapier is pushed into the fell of the fabric, and the flexible and inflatable cover inflated, which both pushes the yarn into the fell of the fabric and performs beatup. The rapier is withdrawn and the shed closed to complete one step of the weaving process.
