Design and implementation of an active database system for receiving broadcast data (2003)

Abstract Satellite‐based data broadcasting has been the focus of increasing attention in recent years due to launches of new broadcasting or communications satellites and the initiation of new services. The popularization of these kinds of broadcasting systems has led to a dramatic increase in both the broadcast volume and types of services. As a result, a system is needed that will enable an ordinary user to efficiently extract, store, and reuse required information from the massive amount of data that is broadcast. In response to this request, the authors propose a super active database system (SADB) and describe its design and implementation. The proposed SADB is an adaptation of an active database, which is an event‐triggered database, to a broadcasting system. Since the SADB must quickly process the massive amount of data that is sent to it, the reception actions and reception data processing were designed independently of the rule processor. This paper evaluates the performance of an implemented system and shows the data volume that it can handle. © 2003 Wiley Periodicals, Inc.

Towards knowledge-based extraction of roads from 1 m-resolution satellite images (2002)

As the IKONOS satellite with 1 m-resolution camera was launched in 1999, mapping using spaceborne images will be an important issue in the computer vision area as well as photogrammetry, mainly because most major man-made objects of interest can be identifiable. One of the automatically identifiable objects of importance may be roads. Detecting roads using edge detection approaches may be very difficult because a number of edge elements from such as buildings, etc., can be generated from edge detector. In this paper, we propose a method for the extraction of approximated road regions based on region segmentation that utilizes region information. Our method consists of the following three steps. First, an image is segmented using the modified hierarchical multi-scale gradient watershed transformation. Then, the road candidates are identified using information about road gray level, elongatedness and connectedness. The identified road candidates are expanded by connecting the close-by roads knowing that roads are connected objects. Our method was tested on the simulated spaceborne images and the result shows that the automation of road extraction is quite promising.
The effect of patient point of entry and Medicaid status on quality outcomes following total hip arthroplasty (2020)

After controlling for patient variables, there was a statistically significant Medicaid effect on LOS and facility discharge. These results indicate that clinically similar outcomes can be achieved for Medicaid patients; however, further work is needed on maximizing social support and preoperative patient education with a focus on successful home discharge.

NM inhibited MMP secretion and Matrigel invasion in FANCA and inhibited invasion and induced toxicity in FANCC lymphoblasts. These results suggest that the NM may have therapeutic potential in Fanconi anemia associated neoplasia.
Iterative channel estimation for turbo equalization over MIMO double selective fading channels (2005)

A novel pilot symbol assisted modulation (PSAM) based iterative channel estimation method over time and frequency selective fading channels is proposed, applied in conjunction with multiple-input-multiple-output (MIMO) turbo equalization. Initial channel estimates are derived from optimal training by maximum likelihood (ML) acquisition and subsequent Wiener filtering. In the iterative channel estimator, the MIMO frequency selective channel is decoupled into multiple single-input-single-output (SISO) flat fading sub-channels by using the soft decisions from the decoder to cancel both the inter-symbol-interference (ISI) and the inter-channel-interference (ICI) from the receive signals. Then refined channel estimates of individual MIMO multipath taps can be obtained independently from the corresponding virtual SISO flat fading channel. Simulation results show bit error ratio (BER) performance gains and normalized mean squared error (MSE) improvements achieved by the iterative channel estimation scheme over those of the non-iterative scheme for normalized fade rates f/sub d/T/sub s/=0.01 and f/sub d/T/sub s/=0.005. The effect of the suboptimal decoupling by the interference cancellation in the iterative estimator is investigated by comparing to the optimal decoupling situation.
Determination of ventricular volumes in coronary artery disease (2006)

Both gated SPECT analysis tools showed reliable volumetric assessments in high-risk patients with CAD and severely reduced LV-EF in comparison to MRI, with advantages for GSQ in terms of postprocessing time. However, for the calculation of LV-EF a markedly lower concordance with MR-results was observed for both methods depending on the presence of myocardial scars.
Yeast R2TP Interacts with Extended Termini of Client Protein Nop58p (2019)

The AAA + ATPase R2TP complex facilitates assembly of a number of ribonucleoprotein particles (RNPs). Although the architecture of R2TP is known, its molecular basis for acting upon multiple RNPs remains unknown. In yeast, the core subunit of the box C/D small nucleolar RNPs, Nop58p, is the target for R2TP function. In the recently observed U3 box C/D snoRNP as part of the 90 S small subunit processome, the unfolded regions of Nop58p are observed to form extensive interactions, suggesting a possible role of R2TP in stabilizing the unfolded region of Nop58p prior to its assembly. Here, we analyze the interaction between R2TP and a Maltose Binding Protein (MBP)-fused Nop58p by biophysical and yeast genetics methods. We present evidence that R2TP interacts largely with the unfolded termini of Nop58p. Our results suggest a general mechanism for R2TP to impart specificity by recognizing unfolded regions in its clients.
Mechanical properties and solubility of fibre obtained from liquid two‐phase systems water‐casein‐sodium alginate (1982)

Abstract The mechanical properties (tensile strength and deformation under uniaxial tension and shearing strength) as well as the stability against dissolution of the fibre obtained from the liquid two‐phase system, water‐casein‐sodium alginate, can be much better than the properties of the fibres produced from binary systems, water‐casein and water‐sodium alginate, when concentrations of the macromolecular components and pH of the system are the same. These properties can be controlled by varying the composition of the system and by additional treatment in a 10% solution of CaCl 2 at 100 °C.
Intravascular lymphomatosis presenting with a conus medullaris syndromemimicking disseminated encephalomyelitis (2002)

We describe the clinical, radiologic, and postmortem findings of a 42-year-old man with intravascular lymphomatosis. The patient presented with a conus medullaris syndrome followed by progressive, disseminated spinal and cerebral symptoms. Disseminated encephalomyelitis was suspected due to the clinical, radiologic, and cerebrospinal fluid findings and the results of a stereotactic brain biopsy, all of which were compatible with inflammatory CNS disease. Treatment with methylprednisolone and cyclophosphamide led to a temporary remission of symptoms. The patient died 13 months after onset of symptoms. The diagnosis of disseminated intravascular lymphomatosis was established after death.
Type 2 Diabetes Restricts Multipotency of Mesenchymal Stem Cells and Impairs Their Capacity to Augment Postischemic Neovascularization in db/db Mice (2012)

Type 2 diabetes-induced oxidant stress restricts the multipotency of MSCs and impairs their capacity to increase blood flow recovery after the induction of hind-limb ischemia. Reversal of MSC oxidant stress might permit greater leverage of the therapeutic potential of MSC transplantation in the setting of diabetes.
Runtime verification for multicore SoC with high-quality trace data (2013)

Multicore System-on-Chip (SoC) implementations of embedded systems are becoming very popular. In these systems it is possible to spread out computations over many cores. On one hand this leads to better energy efficiency if clock frequencies and core voltages are reduced. On the other hand this delivers very high performance to the software developer and thus enables complex software systems to be implemented. Unfortunately, debugging and validation of these systems becomes extremely difficult. Various technological approaches try to solve this dilemma. In this contribution we will show a new approach to observe multi-core SoCs and make their internal operations visible to external analysis tools. Also, we show that runtime verification can be employed to analyze and validate these internal operations while the system operates in its normal environment. The combination of these two approaches delivers unprecedented options to the developer to understand and verify system behavior even in complex multicore SoCs.
LemurFaceID: a face recognition system to facilitate individual identification of lemurs (2017)

Abstract Background Long-term research of known individuals is critical for understanding the demographic and evolutionary processes that influence natural populations. Current methods for individual identification of many animals include capture and tagging techniques and/or researcher knowledge of natural variation in individual phenotypes. These methods can be costly, time-consuming, and may be impractical for larger-scale, population-level studies. Accordingly, for many animal lineages, long-term research projects are often limited to only a few taxa. Lemurs, a mammalian lineage endemic to Madagascar, are no exception. Long-term data needed to address evolutionary questions are lacking for many species. This is, at least in part, due to difficulties collecting consistent data on known individuals over long periods of time. Here, we present a new method for individual identification of lemurs (LemurFaceID). LemurFaceID is a computer-assisted facial recognition system that can be used to identify individual lemurs based on photographs. Results LemurFaceID was developed using patch-wise Multiscale Local Binary Pattern features and modified facial image normalization techniques to reduce the effects of facial hair and variation in ambient lighting on identification. We trained and tested our system using images from wild red-bellied lemurs ( Eulemur rubriventer ) collected in Ranomafana National Park, Madagascar. Across 100 trials, with different partitions of training and test sets, we demonstrate that the LemurFaceID can achieve 98.7% ± 1.81% accuracy (using 2-query image fusion) in correctly identifying individual lemurs. Conclusions Our results suggest that human facial recognition techniques can be modified for identification of individual lemurs based on variation in facial patterns. LemurFaceID was able to identify individual lemurs based on photographs of wild individuals with a relatively high degree of accuracy. This technology would remove many limitations of traditional methods for individual identification. Once optimized, our system can facilitate long-term research of known individuals by providing a rapid, cost-effective, and accurate method for individual identification.
Noise Figure Improvement in InP-Based HEMTs Using Wide Gate Head and Cavity Structure (2011)

The minimum noise figure (NF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">min</sub> ) at 94 GHz was improved effectively by employing a cavity structure in the interconnection process, even though a wide gate head was used in InP-based high-electron-mobility transistors (HEMTs). The wide gate head is effective in improving NF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">min</sub> since gate resistance is reduced, while increased parasitic capacitance at a passivated gate affects the noise figure. Then, the parasitic capacitance was eliminated successfully by employing a cavity structure around the gate region. We measured an NF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">min</sub> of 0.9 dB when the cavity structure was employed in the wide-gate-head HEMTs.
Periodontal Disease as a Specific, albeit Chronic, Infection: Diagnosis and Treatment (2001)

Periodontal disease is perhaps the most common chronic infection in adults. Evidence has been accumulating for the past 30 years which indicates that almost all forms of periodontal disease are chronic but specific bacterial infections due to the overgrowth in the dental plaque of a finite number of mostly anaerobic species such as Porphyromonas gingivalis, Bacteroides forsythus, and Treponema denticola. The success of traditional debridement procedures and/or antimicrobial agents in improving periodontal health can be associated with the reduction in levels of these anaerobes in the dental plaque. These findings suggest that patients and clinicians have a choice in the treatment of this overgrowth, either a debridement and surgery approach or a debridement and antimicrobial treatment approach. However, the antimicrobial approach, while supported by a wealth of scientific evidence, goes contrary to centuries of dental teaching that states that periodontal disease results from a "dirty mouth." If periodontal disease is demonstrated to be a risk factor for cardiovascular disease and stroke, it will be a modifiable risk factor since periodontal disease can be prevented and treated. Since the antimicrobial approach may be as effective as a surgical approach in the restoration and maintenance of a periodontally healthy dentition, this would give a cardiac or stroke patient and his or her physician a choice in the implementation of treatment seeking to improve the patient's periodontal condition so as to reduce and/or delay future cardiovascular events.
Interaction between Hepatitis B Virus Core Protein and Reverse Transcriptase (2000)

Previous mutagenesis studies with hepatitis B virus (HBV) suggest that continued interactions with core are required for several steps in genomic replication. To examine core-polymerase (Pol) interactions, insect cells were coinfected with baculovirus constructs that independently expressed core and Pol. The results demonstrated several features with implications that core plays an interactive role with HBV Pol: (i) core coprecipitated with constructs expressing full-length Pol as well as the terminal protein (TP), reverse transcriptase (RT) and RNase H domains of Pol, independently; (ii) coprecipitation of core was not dependent on the presence of an epsilon stem-loop sequence; and (iii) core-Pol complexes migrated as intact capsid particles, as detected by sucrose gradient analysis. To analyze the structural and sequence requirements of core in recognition of Pol, a series of core mutants with two- to four-amino-acid insertions or carboxy-terminal deletions were assessed for Pol interaction. The results indicated that capsid formation is required but not sufficient for interaction with Pol and that the TP and RT domains of Pol have different requirements for interaction with core. To map the core binding sites on Pol, a panel of amino- and carboxy-terminal deletion mutants of the TP and RT domains of Pol were analyzed for interaction with core. At least three separate core binding sites on Pol were detected. This analysis begins to define basic requirements for core-Pol interactions, but further study is necessary to delineate the effects of these interactions on encapsidation and genome replication.
Coatings Based on Light-Weight Alkali Activated Mortars for Steel Corrosion Protection (2022)

Alkali activated materials and geopolymers have attracted a lot of attention in the last 20 years thanks to their excellent mechanical performances, durability and sustainability properties, especially for civil applications. These materials also exhibit promising properties as fire- and corrosion-resistant protection systems. In a previous study, a 20-mm coating based on light-weight alkali activated mortar (LWAAM) suitable for the protection of steel structures against fire was successfully developed. To understand if the same coating is also able to ensure corrosion protection to steel structures, this study reports the results obtained in two different chloride-rich environments. The corrosion performance of the new system based on steel coated by LWAAM (using expanded perlite and hydrogen peroxide in the mix) was compared with a steel coated by a traditional alkali activated mortar (NWAAM). Electrochemical tests on steel samples immersed in an alkaline solution simulating the pore environment of the binder or embedded in the two different types of mortars were carried out in presence of different chloride concentrations. It was found that the alkaline environment is able to passivate the steel surface, however, the increasing of chloride ions concentration, affects passive film stability and promotes steel corrosion. In presence of low chloride concentration (i.e., 0.2M NaCl), the increased porosity of the LWAAM did not impair the steel corrosion protection, when compared with NWAAM.
Calculation of free surface flows using CONNFFESSIT (2001)

A calculation method for two-dimensional time-dependent free surface flows is presented. The method extends the capabilities of CONNFFESSIT (calculation of non-Newtonian flows: finite elements and stochastic simulation technique) to transient free surface flows. The macroscopic unknowns are the velocity and the pressure fields together with the shape of the free surface. Particle tracking techniques, one of the main components of CONNFFESSIT, are capitalized upon in order to efficiently track the time evolution of the free surface. The ability of CONNFFESSIT to treat models for which no closed-form constitutive equation can be derived and to yield full molecular information is now enhanced with a technique for the calculation of free surface flows. In order to validate the method, transient, free jet swell calculations for the Oldroyd-B fluid using CONNFFESSIT are compared with continuum-mechanics POLYFLOW calculations.

Near-diffraction-limited operation of step-index large-mode-area fiber lasers via gain filtering (2010)

We present, for the first time to our knowledge, an explicit experimental comparison of beam quality in conventional and confined-gain multimode fiber lasers. In the conventional fiber laser, beam quality degrades with increasing output power. In the confined-gain fiber laser, the beam quality is good and does not degrade with output power. Gain filtering of higher-order modes in 28microm diameter core fiber lasers is demonstrated with a beam quality of M(2)=1.3 at all pumping levels. Theoretical modeling is shown to agree well with experimentally observed trends.
Fast Algorithms for Convolutional Neural Networks (2016)

Deep convolutional neural networks take GPU-days of computation to train on large data sets. Pedestrian detection for self driving cars requires very low latency. Image recognition for mobile phones is constrained by limited processing resources. The success of convolutional neural networks in these situations is limited by how fast we can compute them. Conventional FFT based convolution is fast for large filters, but state of the art convolutional neural networks use small, 3 3 filters. We introduce a new class of fast algorithms for convolutional neural networks using Winograd's minimal filtering algorithms. The algorithms compute minimal complexity convolution over small tiles, which makes them fast with small filters and small batch sizes. We benchmark a GPU implementation of our algorithm with the VGG network and show state of the art throughput at batch sizes from 1 to 64.
Palladium‐Catalyzed Construction of Quaternary Stereocenters by Enantioselective Arylation of γ‐Lactams with Aryl Chlorides and Bromides (2019)

Herein, we report the first Pd-catalyzed enantioselective arylation of α-substituted γ-lactams. Two sets of conditions were developed for this transformation, allowing for the use of either aryl chlorides or bromides as electrophiles. Utilizing a highly electron-rich dialkylphosphine ligand we have been able to construct α-quaternary centers in good yields (up to 91 % yield) and high enantioselectivities (up to 97 % ee).
Cell‐based selection provides novel molecular probes for cancer stem cells (2012)

Cancer stem cells (CSC) represent a malignant subpopulation of cells in hierarchically organized tumors. They constitute a subpopulation of malignant cells within a tumor mass and possess the ability to self-renew giving rise to heterogeneous tumor cell populations with a complex set of differentiated tumor cells. CSC may be the cause of metastasis and therapeutic refractory disease. Because few markers exist to identify and isolate pure CSC, we used cell-based Systematic Evolution of Ligands by EXponential enrichment (cell-SELEX) to create DNA aptamers that can identify novel molecular targets on the surfaces of live CSC. Out of 22 putative DNA sequences, 3 bound to ~90% and 5 bound to ~15% of DU145 prostate cancer cells. The 15% of cells that were positive for the second panel of aptamers expressed high levels of E-cadherin and CD44, had high aldehyde dehydrogenase 1 activity, grew as spheroids under nonadherent culture conditions, and initiated tumors in immune-compromised mice. The discovery of the molecular targets of these aptamers could reveal novel CSC biomarkers.
The research progress of two way time synchronization with fiber based on spread spectrum signal (2015)

High-precision time synchronization is a basic element in some areas of aeronautical engineering, such as satellite navigation and deep space exploration. It is more accurate and stable to use the optical fibers while performing time frequency transfer than using other media such as GNSS common view and two-way satellite time frequency transfer. The frequency transfer is the main focus of the current research in optical fiber time frequency transfer. However, there is little study on time transfer, and the accuracy of time transfer is commonly in nanosecond level. In this paper, a two way time transfer method based on spread spectrum ranging is studied. For the proposed method, the accuracy is improved and extra links for data check are not needed any more. The designing schemes and the implementation progress of the engineering prototype are presented. The experimental results indicate that the time synchronization uncertainty is less than 30ps by use of the proposed method when the optical fiber transmission distance is within 2km.
