Continuous media playback and jitter control (2002)

The purpose of this paper is to examine problems associated with display (playback) of live continuous media under varying conditions for an internetwork of workstations running a general purpose operating system such as Unix. Under the assumption that the network cannot guarantee the required bounds on delay and jitter, there is a need to accommodate the delay jitter in the end systems. Various methods of jitter smoothing at the end systems and their suitability to audio as well as video transmission are discussed. An experimental testbed used to investigate these problems is described. Some initial empirical results obtained using this testbed are also presented.
Structural and Textural Changes in Kinu‐Tofu Due to High‐Pressure‐Freezing (1997)

ABSTRACT To determine the effect of high‐pressure‐freezing on quality, kinu‐tofu (soybean curd) was frozen at 100 MPa (ice I), 200 MPa (liquid phase), 340 MPa (ice III), 400, 500, 600 MPa (ice V) or 700 MPa (ice VI) at ca. –20°C for 90 min. After reduction to atmospheric pressure, tofu was stored 2 days at –30°C then thawed at 20°C. Texture and structure were compared with kinu‐tofu frozen (–20°C, –30°C or –80°C) at atmospheric pressure (0.1 MPa). The rupture stress and strain of tofu frozen at 0.1 MPa and 100 MPa increased, but that of tofu frozen at 200 MPa and 340 MPa was similar to untreated tofu. As pressure rose above 500 MPa, rupture stress increased. The ice crystals in tofu frozen at 200 MPa ∼400 MPa were smaller than in tofu frozen at 100 MPa or 700 MPa. Thus, high‐pressure‐freezing at 200 MPa ∼400 MPa was effective in improving the texture of frozen tofu.
Derangements in Endothelial Cell-to-Cell Junctions Involved in the Pathogenesis of Hypercholesterolemia-Induced Erectile Dysfunction (2009)

Down-regulation of the endothelial cell-to-cell junctions and decreased endothelial content in the corpus cavernosum might play a major role in the deterioration of erectile function in hypercholesterolemic mice.

A Spatial Analysis of Basketball Shot Chart Data (2006)

Basketball coaches at all levels use shot charts to study shot locations and outcomes for their own teams as well as upcoming opponents. Shot charts are simple plots of the location and result of each shot taken during a game. Although shot chart data are rapidly increasing in richness and availability, most coaches still use them purely as descriptive summaries. However, a team's ability to defend a certain player could potentially be improved by using shot data to make inferences about the player's tendencies and abilities. This article develops hierarchical spatial models for shot-chart data, which allow for spatially varying effects of covariates. Our spatial models permit differential smoothing of the fitted surface in two spatial directions, which naturally correspond to polar coordinates: distance to the basket and angle from the line connecting the two baskets. We illustrate our approach using the 2003–2004 shot chart data for Minnesota Timberwolves guard Sam Cassell.
Multifractal Formalism for Functions Part II: Self-Similar Functions (1997)

In this paper we introduce and study the self-similar functions. We prove that these functions have a concave spectrum (increasing and then decreasing) and that the different formulas that were proposed for the multifractal formalism allow us to determine either the whole increasing part of their spectrum or a part of it. One of these methods (the wavelet-maxima method) yields their complete spectrum.
Core Knowledge of Geometry in an Amazonian Indigene Group (2006)

Does geometry constitute a core set of intuitions present in all humans, regardless of their language or schooling? We used two nonverbal tests to probe the conceptual primitives of geometry in the Mundurukú, an isolated Amazonian indigene group. Mundurukú children and adults spontaneously made use of basic geometric concepts such as points, lines, parallelism, or right angles to detect intruders in simple pictures, and they used distance, angle, and sense relationships in geometrical maps to locate hidden objects. Our results provide evidence for geometrical intuitions in the absence of schooling, experience with graphic symbols or maps, or a rich language of geometrical terms.
Reinforcement Learning Decoders for Fault-Tolerant Quantum Computation (2018)

Topological error correcting codes, and particularly the surface code, currently provide the most feasible roadmap towards large-scale fault-tolerant quantum computation. As such, obtaining fast and flexible decoding algorithms for these codes, within the experimentally relevant context of faulty syndrome measurements, is of critical importance. In this work, we show that the problem of decoding such codes, in the full fault-tolerant setting, can be naturally reformulated as a process of repeated interactions between a decoding agent and a code environment, to which the machinery of reinforcement learning can be applied to obtain decoding agents. As a demonstration, by using deepQ learning, we obtain fast decoding agents for the surface code, for a variety of noise-models.
Learning to Combine Arbitrary Signals from Vision and Touch (2003)

Humans integrate visual and haptic size information in a statistically optimal fashion (Ernst Banks, 2002). Combining such size estimates is reasonable, because, naturally, both these size cues are correlated. The purpose of this study is to investigate whether cue combination is learned on the basis of a correlation between cues. Therefore, we took naturally uncorrelated cues—the object’s luminance (visual cue) and stiffness (haptic cue)—and trained 12 subjects for 1 h in an environment in which these cues were correlated. To test whether training had an effect, we compared subjects’ discrimination performance before and after training for two intermixed conditions: In one condition, the cues were consistent with the correlation during training (congruent); in the other, the cues were anticorrelated relative to training (incongruent). We predict that discrimination performance becomes slightly better for stimuli with congruent cues and worse for stimuli with incongruent cues. In agreement with our prediction, we found a significant interaction between preand posttest for the two congruent and incongruent conditions ( p < .001). This indicates that subjects picked up the correlation during training and learned to combine two arbitrary cues. We conclude that combination of cues can be learned on the basis of the statistics of their co-occurrence.
Study on the method of transmission line foreign body detection based on deep learning (2017)

Target detection methods based on region proposal are complicated and the detection speed is slow, which is difficult to meet the requirement of real-time detection of massive power inspection pictures. SSD (Single Shot MultiBox Detector) is simpler than the one that requires region proposal, eliminates the generation of proposals and subsequent feature resampling phases, and encapsulates all calculations in a single network. The model is more easily trained while meeting the high accuracy and real-time detection requirements. In this paper, we described the SSD method in detail, compared and analyzed the DPM (Deformable Parts Model), Faster R-CNN and SSD methods. The three methods are tested and verified by using the actual data set of transmission line foreign body, and the influence of different parameters on the identification results is discussed. The experimental results show that the SSD method can achieve 85.2% of the mAP(mean average precision) at 26FPS (GTX1050Ti), it can meet the real-time requirements while ensuring the accuracy of detection, and the feasibility of the recognition method based on deep learning is verified in real time foreign body detection of transmission line.
Performance analysis of a time diversity ARQ in land mobile radio (1989)

A time diversity automatic repeat-request (ARQ) scheme with a finite number of transmissions is investigated for a digital FM mobile radio with frequency demodulation (FD). It processes all the retransmissions of a single data block using postdetection diversity combining. The analysis of the signal energy per bit required for a given bit error rate (BER) and the spectral efficiency in a cellular mobile radio system are presented. The results obtained from the numerical calculations show that this ARQ scheme offers a performance superior to both the basic ARQ scheme and the time-diversity scheme.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Addition of <i>p</i>-Azido-<scp>l</scp>-phenylalanine to the Genetic Code of <i>Escherichia </i><i>c</i><i>oli</i> (2002)

We report the selection of a new orthogonal aminoacyl tRNA synthetase/tRNA pair for the in vivo incorporation of a photocrosslinker, p-azido-l-phenylalanine, into proteins in response to the amber codon, TAG. The amino acid is incorporated in good yield with high fidelity and can be used to crosslink interacting proteins.
Laser-based road recognition for a smart electric wheelchair (2011)

This paper describes a method of road recognition, which is useful in outdoor environments, using a multi-layered laser range finder (MLRF) for a smart electric wheelchair. Road recognition means detecting the road in front of a wheelchair on which it can travel. The MLRF captures laser scanned images from the road surface and maps them onto a grid map. Paved roads are almost flat and have boundaries such as curbs, ditches or raised edges. We detect road flatness based on random sample consensus (RANSAC) method and estimate the shape of the road boundary based on a cubic (third-ordered) spline. Experimental results in our university campus show the feasibility of our method.
A complex signaling cascade links the serotonin<sub>2A</sub> receptor to phospholipase A<sub>2</sub> activation: the involvement of MAP kinases (2003)

Previous studies in our laboratory have shown that in NIH3T3-5HT2A cells, 5-HT-induced AA release is PLA2-coupled and independent of 5-HT2A receptor-mediated PLC activation. Although 5-HT2A receptor-mediated PLC activation is known to be Galphaq-coupled, much less is understood about 5-HT2A receptor-mediated PLA2 activation. Therefore, the studies presented here were aimed at elucidating the signal transduction pathway linking stimulation of the 5-HT2A receptor to PLA2 activation. By employing various selective inhibitors, toxins, and antagonistic peptide constructs, we propose that the 5-HT2A receptor can couple to PLA2 activation through two parallel signaling cascades. Initial experiments were designed to examine the role of pertussis toxin-sensitive G proteins, namely Galphai/o, as well as pertussis toxin-insensitive G proteins, namely Galpha12/13, in 5-HT-induced AA release. Furthermore, inactivation of both Gbetagamma heterodimers and Rho proteins resulted in decreased agonist-induced AA release, without having any effect on PLC-IP accumulation. We also demonstrated 5-HT2A receptor-mediated phosphorylation of ERK1,2 and p38. Moreover, pretreatment with selective ERK1,2 and p38 inhibitors resulted in decreased 5-HT-induced AA release. Taken together, these results suggest that the 5-HT2A receptor expressed in NIH3T3 cells can couple to PLA2 activation though a complex signaling mechanism involving both Galphai/o-associated Gbetagamma-mediated ERK1,2 activation and Galpha12/13-coupled, Rho-mediated p38 activation.

The Efficient, Enantioselective Synthesis of Aza Sugars from Amino Acids. 1. The Polyhydroxylated Pyrrolidines (1997)

Beginning with (+)-serine or (-)-serine, as appropriate, convenient, high-yield, enantioselective synthesis of all eight stereoisomeric 2-hydroxymethyl-3,4-dihydroxypyrrolidines (the enantiomeric pairs of iminoribitol, -arabinitol, -xylitol, and -lyxitol) can be effected. The absolute configuration of the starting amino acid defines the set of azasugars produced.
Detection of Explosives and Related Compounds by Low-Temperature Plasma Ambient Ionization Mass Spectrometry (2010)

Detection of explosives is important for public safety. A recently developed low-temperature plasma (LTP) probe for desorption and ionization of samples in the ambient environment ( Anal. Chem. 2008 , 80 , 9097 ) is applied in a comprehensive evaluation of analytical performance for rapid detection of 13 explosives and explosives-related compounds. The selected chemicals [pentaerythritol tetranitrate (PETN), trinitrotoluene (TNT), cyclo-1,3,5-trimethylenetrinitramine (RDX), tetryl, cyclo-1,3,5,7-tetramethylenetetranitrate (HMX), hexamethylene triperoxide diamine (HMTD), 2,4-dinitrotoluene, 1,3-dinitrobenzene, 1,3,5-trinitrobenzene, 2-amino-4,6-dinitrotoluene, 4-amino-2,6-dinitrotoluene, 2,6-dinitrotoluene, and 4-nitrotoluene) were tested at levels in the range 1 pg-10 ng. Most showed remarkable sensitivity in the negative-ion mode, yielding limits of detection in the low picogram range, particularly when analyzed from a glass substrate heated to 120 °C. Ions typically formed from these molecules (M) by LTP include [M + NO(2)](-), [M](-), and [M - NO(2)](-). The LTP-mass spectrometry methodology displayed a linear signal response over three orders of magnitude of analyte amount for the studied explosives. In addition, the effects of synthetic matrices and different types of surfaces were evaluated. The data obtained demonstrate that LTP-MS allows detection of ultratrace amounts of explosives and confirmation of their identity. Tandem mass spectrometry (MS/MS) was used to confirm the presence of selected explosives at low levels; for example, TNT was confirmed at absolute levels as low as 0.6 pg. Linearity and intra- and interday precision were also evaluated, yielding results that demonstrate the potential usefulness and ruggedness of LTP-MS for the detection of explosives of different classes. The use of ion/molecule reactions to form adducts with particular explosives such as RDX and HMX was shown to enhance the selectivity and specificity. This was accomplished by merging the discharge gas with an appropriate reagent headspace vapor (e.g., from a 0.2% trifluoracetic acid solution).
The immunology of virus infection in asthma (2001)

The respiratory tract is commonly infected by a range of viruses with overlapping pathologies. The majority of episodic exacerbations of asthma are associated with viral infection, in particular with rhinovirus infections. Experimental rhinovirus infection in human volunteers provides a useful model of natural virus-induced asthma. The asthmatic airway is characterized by an infiltrate of eosinophils and T-lymphocytes expressing the type 2 cytokines interleukin (IL)-4, IL-5 and IL-13. An effective antiviral immune response requires early viral clearance and appropriate termination of the immune response to minimize associated immunopathology and tissue damage. The antiviral immune response is made up of innate (nonspecific) and specific components, and requires the coordinated actions of many different cell types including neutrophils, macrophages, eosinophils, dendritic cells, epithelial cells, mast cells, natural killer cells and B- and T-lymphocytes. Coordination of this response involves numerous cytokines and chemokines. T-lymphocytes expressing type 1 cytokines including interferon-gamma play a key role. Pre-existing asthmatic inflammation in the lower airway may modify the immune response to viral infection by altering the balance of T-cell cytokine expression from type 1 towards a type 2 in what is always a mixed response. The consequence is delayed viral clearance, persistent virus-induced inflammation and amplification of the allergic inflammation.
Small molecule inhibitors for polo box domain dependent recognition (2007)

A110 Polo-like kinase 1 (Plk1) is one of the key regulator of mitotic cell division and is highly expressed in various human tumors. Besides the N-terminal protein kinase catalytic domain, Plk1 contains a phosphopeptide binding domain in its C-terminus, the Polo box domain (PBD). The PBD-dependent binding is postulated to be essential for Plk1 localization and substrate targeting. Previously, we found that the binding of PBD to human somatic Wee1 (Wee1A) is quite important for the recognition of Wee1A by an F-box protein, β-TrCP. The ubiquitination by SCF β-TrCP of Wee1A and its proteasome dependent degradation are essential for the rapid initiation of mitosis.  In this study, we have developed a high throughput screening system to identify small molecule inhibitors of PBD-dependent binding. The binding of fluorescent protein fused PBD to phosphopeptides of Wee1A sequence was measured under microtiter plate basis. When small molecules that compete the phosphopeptides to bind PBD exist in the assay, the fluorescent binding signal of PBD and phosphopeptides will reduce. We implemented this assay in a screen of compounds that are stored in Riken NPDepo (Natural Products Depository). We found several hit compounds and one of them (204115F03) actually inhibited the binding between PBD and Wee1A. When this compound was applied to synchronized HeLa cells, the compound not only retarded the onset of mitosis, but arrested the cells at metaphase. Although apparently normal bipolar spindles were formed even in the presence of the compounds, the alignment of chromosomes at metaphase plates was perturbed, which seemed to induce the activation of the spindle assembly checkpoint pathway. Using this compound, we are analyzing the role of PBD dependent binding on the mitotic spindle formation.
Reversing the Reverse Cohesion Effect: Good Texts Can Be Better for Strategic, High-Knowledge Readers (2007)

Abstract Students with low knowledge have been shown to better understand and learn more from more cohesive texts, whereas high-knowledge students have been shown to learn more from lower cohesion texts; this has been called the reverse cohesion effect. This study examines whether students' comprehension skill affects the interaction between text cohesion and their domain knowledge. College students (n= 143) read either a high- or a low-cohesion text and answered text-based and bridging inference questions. The results indicated that the benefit of low-cohesion text was restricted to less skilled, high-knowledge readers, whereas skilled comprehenders with high knowledge benefited from a high-cohesion text. Consistent with CitationMcNamara (2001), the interaction of text cohesion and knowledge was restricted to text-based questions. In addition, for low-knowledge readers, the benefits of high-cohesion texts emerged in their responses to bridging inference questions but not text-based questions. The results suggest a more complex view of when and for whom textual cohesion affects comprehension.

Multidimensional separations of ubiquitin conformers in the gas phase: Relating ion cross sections to H/D exchange measurements (2005)

Investigating gas-phase structures of protein ions can lead to an improved understanding of intramolecular forces that play an important role in protein folding. Both hydrogen/deuterium (H/D) exchange and ion mobility spectrometry provide insight into the structures and stabilities of different gas-phase conformers, but how best to relate the results from these two methods has been hotly debated. Here, high-field asymmetric waveform ion mobility spectrometry (FAIMS) is combined with Fourier-transform ion cyclotron resonance mass spectrometry (FT/ICR MS) and is used to directly relate ubiquitin ion cross sections and H/D exchange extents. Multiple conformers can be identified using both methods. For the 9+ charge state of ubiquitin, two conformers (or unresolved populations of conformers) that have cross sections differing by 10% are resolved by FAIMS, but only one conformer is apparent using H/D exchange at short times. For the 12+ charge state, two conformers (or conformer populations) have cross sections differing by <1%, yet H/D exchange of these conformers differ significantly (6 versus 25 exchanges). These and other results show that ubiquitin ion collisional cross sections and H/D exchange distributions are not strongly correlated and that factors other than surface accessibility appear to play a significant role in determining rates and extents of H/D exchange. Conformers that are not resolved by one method could be resolved by the other, indicating that these two methods are highly complementary and that more conformations can be resolved with this combination of methods than by either method alone.
Partitioning VLSI-Circuits for Parallel Simulation on Transistor Level (1997)

For parallel simulation of VLSI circuits on transistor level a sophisticated partitioning of the circuits into subcircuits is crucial. Each net connecting the subcircuits causes additional communication and computation effort. As the slave processors simulating the subcircuits advance synchronously in time, the computation effort for each subcircuit should be approximately the same. In this paper we present a new approach for partitioning VLSI circuits on transistor level yielding a low number of interconnects and balanced subcircuit sizes. Simulation of industrial circuits using this partitioning is up to 41.
Highly reliable InAlAs/InGaAs heterojunction FETs fabricated using completely molybdenum-based electrode technology (COMET) (2002)

This paper describes high performance and high reliability InAlAs/InGaAs heterojunction FETs fabricated using completely molybdenum-based electrode technology "COMET", in which a Mo/Ti/Pt/Au Schottky gate and Mo/Ti/Pt/Au non-alloyed ohmic electrodes are successfully employed. The superior reliability of the COMET-FETs is attributed to the reduction of the interdiffusion between metals (gate or ohmic) and semiconductors (InAlAs or InGaAs) by Mo insertion.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Detection of Rhinovirus in Turbinate Epithelial Cells of Chronic Sinusitis (2006)

The detection of RV in the turbinate epithelial cells of chronic sinusitis patients suggests that RV may be important in the pathogenesis of chronic sinusitis.
