Topic word selection for blogs by topic richness using web search result clustering (2012)

Blogs are one of popular services to publish and archive posts with personal opinions on the web. The topics of a blog can be used for classification, recommendation, opinion mining, and ranking, etc. In this paper, we propose a method for extracting important topic words from a blog. Our method selects topic words by measuring whether the blog includes rich content on the word. To measure the richness of a blog on candidate topic words, we compare web search results by the candidate words with the content of the blog. We used document clustering and cluster matching in order to compare them.
Differential Expression of Type A and Type B Monoamine Oxidase of Mouse Astrocytes in Primary Cultures (1982)

Abstract: Type A and type B monoamine oxidase (MAO) activities were determined in mouse brain and in primary cultures of mouse astrocytes. Thirty‐one‐day‐old astrocyte cultures exhibited predominantly type A MAO activity. In cultures of the same age, treated with 0.25 mM dibutyryl cyclic AMP under the same culturing conditions, 30% type B MAO was expressed, although dibutyryl cyclic AMP up to 1 mM does not affect MAO activity in vitro. The specific activity of type B MAO increased significantly in older cultures, while type A MAO changed only slightly.
Fermi level depinning in metal/Ge Schottky junction for metal source/drain Ge metal-oxide-semiconductor field-effect-transistor application (2009)

Schottky barrier height modulation in metal/Ge Schottky junction was demonstrated by inserting an ultrathin interfacial silicon nitride layer. The SiN interfacial layer suppressed strong Fermi level pinning in metal/Ge Schottky junction, which resulted in effective control of Schottky barrier height. Metal/SiN/Ge Schottky diode was systematically investigated in terms of SiN thickness dependence and metal work function dependence. At an optimal SiN thickness, Ohmic contact between metal and Ge was obtained as a result of Fermi level depinning, and almost ideal Schottky barrier height determined by the work function difference between the metal and Ge was achieved. This technology was finally applied to metal source/drain Ge metal-oxide-semiconductor field-effect-transistors with low source/drain resistance.
Crystallization of NAD+ synthetase fromBacillus subtilis (1996)

NAD(+)-synthetase is a ubiquitous enzyme catalyzing the last step in the biosynthesis of NAD+. Mutants of NAD+ synthetase with impaired cellular functions have been isolated, indicating a key role for this enzyme in cellular metabolism. Crystals of the enzyme from Bacillus subtilis suitable for x-ray crystallographic investigation have been grown from polyethylene glycol solutions. Investigation on the structural organization of NAD+ synthetase, an enzyme fundamental for NAD+ biosynthesis, and belonging to the recently characterized amidotransferase enzymatic family, will provide more insight into the catalytic mechanism of deamido-NAD+-->NAD+ conversion, a biosynthetic process that is a potential target for the development of antibiotic compounds against Bacillus sp. and related bacteria.
Evidence that the gap junction protein connexin-43 is the ATP-induced pore of mouse macrophages (1991)

Extracellular ATP4- opens pores in the plasma membrane of mouse macrophages and the J774 macrophage-like cell line that allow molecules as large as fura-2 (831 daltons) to enter the cytoplasmic matrix of the cells. The functional similarity of the ATP-induced pores to gap junctions led us to examine whether these pores were related to members of the connexin family of gap junction proteins. Under conditions of high stringency, RNA isolated from J774 cells hybridized with cDNA for connexin-43 but not with cDNA for connexin-32, -26, or -46. RNA isolated from several variant J774 cell lines that do not permeabilize in response to extracellular ATP (ATPR cells) did not hybridize with connexin-43 cDNA. Immunoblots demonstrated that J774 cells, but not the variant ATPR B2 cell line, expressed connexin-43 protein. These studies demonstrate that mouse macrophages express the connexin-43 gap junction mRNA and protein and strongly suggest that in these cells connexin-43 forms "half-gap junctions" in response to extracellular ATP4-.
Analysis of Sperm Whale Click by MUSIC Algorithm (2006)

Inter-pulse interval (IPI) of the click projected from a sperm whale (phyeter macrocephalse) is expected to represent its size. IPI can be regarded as a distinguishing feature between individual sperm whales. Correlation analysis is used to measure IPI from recorded data. We analyzed data recorded off Ogasawara from 2003 to 2005 based on the correlation analysis. Although the results show its applicability for identification of individuals in data of 2003, it does not provide reasonable results for data recorded in 2004 and 2005, which include more noise comparing to those of 2003 when the noise in support vessel is not negligible. In this paper, we propose a new analysis method of sperm whale click based on MUSIC (multiple signal classification) algorithm in order to calculate IPI. MUSIC algorithm is the high-resolution frequency estimation method using orthogonality of signal and noise subspaces. It is said that it has high capacity for white noise. By estimating IPI from clicks data by proposed method and comparing to them to those by convention method, we examine applicability of MUSIC algorithm to classify individuals of sperm whale of analysis of data recorded in 2003. The result shows that proposed method can extract IPI in good conformity with those by convention method under the condition of low lever noise.
Anthocyanins Accumulation and Related Gene Expression in Red Orange Fruit Induced by Low Temperature Storage (2005)

The aim of this work was to study the impact of moderately long storage periods at 4 degrees C upon red orange [Citrus sinensis (L.) Osbeck] anthocyanins production and the expression of structural genes involved in their biosynthesis such as phehylalanine ammonia lyase (PAL), chalcone synthase (CHS), dihydroflavonol 4-reductase (DFR), and UDP-glucose flavonoid glucosyl transferase (UFGT). Our results showed that low temperature-induced anthocyanins accumulation in red orange juice vesicles after 75 days reached values eight times higher than those kept at 25 degrees C. Furthermore, real-time polymerase chain reaction showed that expression of PAL, CHS, DFR, and UFGT was strongly induced during low temperature exposure since levels of all transcripts increased at least 40-fold with respect to control samples. Interestingly, in orange fruits subjected to a brief exposure at low temperature (45 days) and subsequently kept at 25 degrees C, the anthocyanins content dropped although samples still maintained higher levels of these pigments than those registered in control oranges. Concordantly, the expression of chs, dfr, and ufgt declined upon return to control conditions, but it was always much higher in samples subjected to brief cold induction than in the control samples. On the contrary, the amount of PAL transcripts became negligible immediately after the temperature change from 4 to 25 degrees C, thus indicating that "early" and "late" genes, respectively, implicated in the first and in the last steps leading to the anthocyanins, might be affected by different regulation mechanisms.
Robust three-state PFD architecture with enhanced frequency acquisition capabilities (2004)

The three-state phase-frequency detector (PFD) is commonly used to improve the pull-in range of phase-locked loops, due to its ability to operate also in a frequency discriminator mode. However the delay of the feedback path, needed to eliminate the dead zone problem, limits the speed performance of the circuit and its linear input range, and can lead to average differential outputs with the wrong polarity, which disturb the acquisition process of the PLL. In this paper we present an alternative implementation of a three-state PFD, that with simple hardware modifications solves the problem of output polarity reversal, achieving much better frequency acquisition capabilities. The architecture does not rely on any assumption on the underlying VLSI technology.
Codes for QPSK modulation with invariance under 90 degrees rotation (1988)

The new rate 1/2 nonlinear convolutional codes for quadrature phase shift keying (QPSK) modulation allow the achievement of full 90 degree rotational invariance of coded QPSK signal sequences at no significant loss in real coding gains when compared to linear codes. For mobile communication systems operating in a fading environment with frequent periods of low signal-to-noise ratio and the possibility of losses of carrier phase synchronization in the receiver, the invariance to 90 degree ambiguous demodulation should be a significant advantage.
Short-Term Effects of Glucosyl Hesperidin and Hesperetin on Blood Pressure and Vascular Endothelial Function in Spontaneously Hypertensive Rats (2008)

Glucosyl hesperidin (G-hesperidin) is a water-soluble derivative of hesperidin. In the present study, the short-term effects of G-hesperidin and hesperetin, a putative metabolite of G-hesperidin, in spontaneously hypertensive rats (SHR) and in normotensive Wistar-Kyoto rats (WKY) were investigated. Single oral administration of G-hesperidin (10 to 50 mg/kg) induced a dose-dependent reduction in systolic blood pressure (SBP) in SHR, but had no effects in WKY. Intraperitoneal injection of hesperetin (50 mg/kg) into SHR also caused a significant reduction in SBP. The depressor effect was significantly inhibited by a nitric oxide synthase inhibitor, N(G)-nitro-L-arginine methyl ester. Moreover, hesperetin (10(-5) M) enhanced endothelium-dependent relaxation induced by acetylcholine, but had no effect on endothelium-independent relaxation induced by sodium nitroprusside in isolated aortas from SHR. These data suggest that the hypotensive effect of hesperetin in SHR is associated with nitric oxide-mediated vasodilation. Therefore, this effect may be involved in the mechanisms by which G-hesperidin lowers blood pressure in hypertension.
On Aromatic Electrophilic Substitution Promoted by In Situ Generated Thionium Ions (2013)

α-Sulfanylated α-arylacetates and -thioacetates were prepared via ethylthiomethylation reaction of aromatic compounds. These aromatic electrophilic substitutions were performed by in situ generation of the thionium ions by reacting trifluoroacetic anhydride and <i>S</i>-ethyl 2-(ethylsulfinyl)ethanethioate or ethyl 2-(ethylsulfinyl)acetate in the presence of Lewis acids. Some mechanistic features of these ethylthiomethylation reactions are also presented.
What Price Smalltalk? (1987)

In anticipation of the promise of tremendous hardware advances, software researchers have fashioned expansive programming environments to improve programmer productivity. Even with the march of technology, exploratory programming environments such as Smalltalk-80 require such expensive computers that few programmers can afford them. With the hope of increasing that community, a research project at the University of California created a reduced instruction set computer for Smalltalk called SOAR, which stands for Smalltalk on a RISC. The authors are now able to estimate the performance implications of the Smalltalk-80 programming environment. In the next section the authors list the demands that Smalltalk-80 places on traditional computer systems, then present software and hardware ideas that answer those demands.
Uncooled thermal imaging at Texas Instruments (1993)

Texas Instruments is active in productizing uncooled thermal imaging systems for commercial and military products. The technology is based on the field-enhanced pyroelectric effect in ferroelectric barium-strontium titanate. The detector is mated to a readout IC (ROIC) via bump-bonding, and the single output from the ROIC is processed serially to provide both 8-bit digital and NTSC video outputs. Overall system cost is minimized and the electronics are simplified by using a scene-averaging chopper and operating the detector in its inherently ac- coupled mode. The past two years have been devoted to improving producibility, primarily of the uncooled focal plane array (UFPA) and its package. The result is a detector process that is 95% compatible with standard silicon processing. Although explicit performance improvement has been a secondary priority, the producibility improvements have led to a factor of two improvement in sensitivity. Recently demonstrated NETD is 0.047 degree(s)C with f/1 optics.
Pedestrian Detection for a Near Infrared Imaging System (2008)

This paper considers pedestrian detection, specialized for a near infrared imaging system at night. The main objective is the detection of a distant pedestrian, beyond an illuminated area in a low-beam mode, using a monocular on-board camera. In this method, the region of interest (ROI) is first selected by extracting bright regions, and shape information from a whole human body, is later used for verification. Motion information is not used, due to difficulties in cancellation of ego-motion. The ROI selector is implemented by a modified boosted cascade, in combination with dynamic perspective constraints. After filtering out typical non-pedestrian objects, the remaining ROIs are verified using a support vector machine (SVM). The verified ROIs are tracked with a simple alpha-beta tracker, in combination with final validation, based on a classification score from the SVM. The effectiveness of the proposed modules has been confirmed using several typical night time scenarios.

Reassembling fractured objects by geometric matching (2006)

We present a system for automatic reassembly of broken 3D solids. Given as input 3D digital models of the broken fragments, we analyze the geometry of the fracture surfaces to find a globally consistent reconstruction of the original object. Our reconstruction pipeline consists of a graph-cuts based segmentation algorithm for identifying potential fracture surfaces, feature-based robust global registration for pairwise matching of fragments, and simultaneous constrained local registration of multiple fragments. We develop several new techniques in the area of geometry processing, including the novel integral invariants for computing multi-scale surface characteristics, registration based on forward search techniques and surface consistency, and a non-penetrating iterated closest point algorithm. We illustrate the performance of our algorithms on a number of real-world examples.
The Role of Team and Task Characteristics in R&D Team Collaborative Problem Solving and Productivity (1978)

Antecedents of collaborative problem solving in R&D teams have received little attention. Furthermore, the relationship between this form of problem solving and R&D team productivity remains unarticulated. This lacuna is addressed in the present study be analyzing the relationships between task and team, properties, collaborative problem solving and team productivity. Multiple regression was used to study the relationships among these variables. Results indicated that team cohesiveness and task certainty were robust predictors of collaborative problem solving and productivity for 45 R&D project groups. It was found that collaborative problem solving did not have a linear relationship with team productivity The collaborative problem solving-productivity relationship was further examined and it was shown that the relationship was sensitive to high and low levels for each of four predictors used in the research design (task certainty, task interdependence, team size, and team cohesiveness). These empirical findings were then translated into implications for R&D managers.
Transponder-EKG - T-ECG (1997)

Apart from X-rays, the electrocardiogram (ECG) is probably the most frequently employed routine investigation. The 24-hour (Holter) ECG is a valuable diagnostic tool both for the general practitioner and the cardiologist. For the patient, the procedure can be experienced as something of a nuisance during the course of his/her normal life. Not least of the reasons for this are the leads connecting the electrodes to the device, which impair the movements of the patient's trunk. In addition, the patient feels constrained by a desire to avoid the disconnection of the electrodes by uncontrolled movements. Despite positive findings obtained by other means, this situation often leads to false negative results, making repetition of the procedure at some later date.
Cholesteryl Glucoside Stimulates Activation of Protein Kinase B/Akt in the Motor Neuron-Derived NSC34 Cell Line. (2008)

Steryl glycosides and related compounds are commonly found in the environment and have been associated with neurodegenerative changes in vulnerable individuals. However, their mechanisms of action in mammalian cells have not been well investigated. In the present study the effects of cholesterol glucoside (CG), a variant form of steryl glycoside, was investigated in the motor neuron-derived NSC34 cell line. Prolonged treatment with CG was found to induce cell death in a dose- and time-dependent manner. However, transient exposure of CG preconditioned NSC34 cells for stress from serum deprivation. To study the signaling pathways activated by CG, we employed the Kinetworks™ KPSS 1.3 Phospho-site Screen to track the phosphorylation level of at least 35 diverse signaling proteins. The survival protein kinase B (PKB/Akt) displayed a 2-fold increase in phosphorylation at its Ser-473 activation site following CG stimulation. Akt signaling was important for conferring cytoprotection against serum deprivation-induced stress. Inhibition of phosphatidylinositol 3-kinase (PI3K), which indirectly triggers Akt stimulation, completely abolished CG preconditioning against serum deprivation. Our findings revealed that there may be a PI3K-independent pathway which also mediated Akt Ser-473 phosphorylation. Improved understanding of the mechanisms of action of CG should provide insights to the how other members of the steryl glycoside family induce toxicity in the mouse model of ALS-PDC, and how cells respond to these toxins.

An MRAM-Based Deep In-Memory Architecture for Deep Neural Networks (2019)

This paper presents an MRAM-based deep in-memory architecture (MRAM-DIMA) to efficiently implement multi-bit matrix vector multiplication for deep neural networks using a standard MRAM bitcell array. The MRAM-DIMA achieves an 4.5 × and 70× lower energy and delay, respectively, compared to a conventional digital MRAM architecture. Behavioral models are developed to estimate the impact of circuit non-idealities, including process variations, on the DNN accuracy. An accuracy drop of ≤ 0.5% (≤ 1%) is observed for LeNet-300-100 on the MNIST dataset (a 9-layer CNN on the CIFAR-10 dataset), while tolerating 24% (12%) variation in cell conductance in a commercial 22 nm CMOS-MRAM process.

Corporate Information Security Investment Decisions (2018)

This article describes how with information security steadily moving up on board room agendas, security programs are found to be under increasing scrutiny by practitioners. This level of attention by senior business leaders is new to many security professionals as their field has been of limited interest to non-executive directors so far. Currently, they have to regularly report on efficiency and value of their security capabilities whilst being measured against business priorities. Based on the Grounded Theory approach, the authors analysed the data gathered in a series of interviews with senior professionals in order to identify key factors in the context of information security investment decisions. The authors present detailed findings in context of a simplified framework that security practitioners can utilise for critical review or improvements of investment decisions in their own environments. Extensive details for each category as extracted through a qualitative data analysis are provided along with a category network analysis that highlights strong relationships within the framework.
Design and application of esterase-labile sulfonate protecting groups (2011)

Three esterase-labile, but chemically-stable sulfonate protecting groups have been designed and synthesized. One of these sulfonate esters allowed the cytoplasmic delivery and unmasking of a sulfonated dye in live cells.
Novel Immunotherapeutic Strategies of Gastric Cancer Treatment (2011)

Gastric cancer (GC) is the fourth most common cancer and the second most frequent cause of cancer-related deaths, accounting for 10.4% of cancer deaths worldwide. Despite the improvements, estimated cure rates for patients with advanced stages remain poor, and in the metastatic setting, chemotherapy is the mainstay of palliative therapy and results in objective response rates (ORRs) of only 20-40% and median overall survivals (OS) of 8-10 months. Therefore, many investigators believe that the potential for making significant progress lies in understanding and exploiting the molecular biology of these tumors to investigate new therapeutic strategies to combat GC, such as specific immunotherapy. In this paper, we analyze the different approaches used for immune-based (especially dendritic and T cells) therapies to gastric cancer treatment and discuss the results obtained in preclinical models as in clinical trials.
