Video compressive sensing using spatial domain sparsity (2009)

We present a compressive sensing video acquisition scheme that relies on the sparsity properties of video in the spatial domain. In this scheme, the video sequence is represented by a reference frame, followed by the difference of measurement results between each pair of neighboring frames. The video signal is reconstructed by first reconstructing the frame differences using 1 minimization algorithm, then adding them sequentially to the reference frame. Simulation results on both simulated and real video sequences show that when the spatial changes between neighboring frames are small, this scheme provides better reconstruction results than existing compressive sensing video acquisition schemes, such as 2-D or 3-D wavelet methods and the minimum total-variance (TV) method. This scheme is suitable for compressive sensing acquisition of video sequences with relatively small spatial changes. A method that estimates the amount of spatial change based on the statistical properties of measurement results is also presented.
Yeast acetyl-CoA carboxylase: In vitro phosphorylation by mammalian and yeast protein kinases (1990)

Acetyl-CoA carboxylase (ACC) is regulated in mammalian tissues, in part, by multisite enzyme phosphorylation. Yeast ACC (Y-ACC) has been highly purified from S. cerevisiae by monomeric avidin-Sepharose chromatography, revealing an enzyme subunit species of molecular mass 265,000 Da. Unlike mammalian enzyme, Y-ACC is citrate-independent, and reacts weakly or not at all with a panel of anti-rat liver ACC antibodies. Like rat ACC, Y-ACC is rapidly phosphorylated and inactivated by two mammalian carboxylase kinases, the cAMP-dependent protein kinase and 5'-AMP-stimulated kinase. It is also phosphorylated by rat liver casein kinase II, but without any change in catalytic activity. Three major yeast protein kinases active on ACC have been fractionated; all co-elute with kinases active on casein, but each appears to be a distinct catalytic species. Like the mammalian casein kinases, however, phosphorylation of ACC by these yeast kinases does not alter yeast ACC activity. Taken together, these data indicate that Y-ACC possesses at least two classes of phosphorylation sites, one or more of which acutely regulates enzyme activity. Alterations in Y-ACC phosphorylation in yeast, as in mammalian tissues, could be an important modulator of the rates of fatty acid synthesis.
Impurity radiation losses from a high temperature plasma (1961)

This discussion will be concerned with the general problem of enhanced radiation losses from a hydrogen plasma containing a small percentage, particle-wise, of high Z impurities. Because the intrinsic radiation rate per atom from impurities can be many orders of magnitude greater than the Bremsstrahlung radiation from ionized hydrogen, even a small fractional impurity content can greatly increase the total escaping radiation flux.
New Equalizer Optimization Method for Partial Response Maximum Likelihood Systems Using Normal Equation with Sequenced Amplitude Margin (2005)

A new equalizer optimization method was proposed for partial response maximum likelihood systems. It provides a wider tangential tilt margin and defocus margin in an optical disk system that uses a blue laser (406 nm) and has a numerical aperture of 0.85.
Towards detecting target link flooding attack (2014)

A new class of target link flooding attacks (LFA) can cut off the Internet connections of a target area without being detected because they employ legitimate flows to congest selected links. Although new mechanisms for defending against LFA have been proposed, the deployment issues limit their usages since they require modifying routers. In this paper, we propose LinkScope, a novel system that employs both the end-to-end and the hop-by-hop network measurement techniques to capture abnormal path performance degradation for detecting LFA and then correlate the performance data and traceroute data to infer the target links or areas. Although the idea is simple, we tackle a number of challenging issues, such as conducting large-scale Internet measurement through noncooperative measurement, assessing the performance on asymmetric Internet paths, and detecting LFA. We have implemented LinkScope with 7174 lines of C codes and the extensive evaluation in a testbed and the Internet show that LinkScope can quickly detect LFA with high accuracy and low false positive rate.
Lumped parameter models for single- and multiple-layer inductors (2002)

A method for modeling inductors under high-frequency operation is presented. The method is based on analytical approaches which can predict turn inductances, turn-to-turn and turn-to-core capacitances using physical structure of windings. Turn inductances, turn-to-turn and turn-to-core capacitances of coils are then introduced into suitable lumped parameter equivalent circuits of inductors. The overall inductance and stray capacitance can be obtained through the use of the equivalent circuits. Both single- and multiple-layer inductors are considered. The method was tested with experimental measurements. The accuracy of the results was good in most cases. The derived expressions can be useful for the design of HF inductors and can also be used for simulation purposes.

Randomized single-blind trial of topical ketanserin for healing acceleration of diabetic foot ulcers. (1997)

The objective of this study was to determine the efficacy of topically applied ketanserin for healing acceleration of diabetic foot ulcers. From August 1993 to September 1994, 140 NIDDM patients entered a randomized single-blind trial of topical ketanserin (Sufrexal, Janssen Pharmaceuticals; n = 69) vs. normal saline (labeled here as placebo; n = 71). All patients were subjected to surgical debridement of necrotic tissue and lavage with normal saline. Wounds were < 100 cm2 in area. Persons with NIDDM and foot ulcers Wagner 2 and 3 with a median of 8 (interquartile range 4-26) weeks duration were included. Ulcer area was measured at 0, 4, 8 and 12 weeks. The groups were similar in age, sex, years of diabetes duration, obesity, ulcer Wagner type, number of previous amputations and surgical debridements during this hospital stay. Average percent reduction in ulcer area at 12 weeks was 87% for ketanserin vs. 63% for placebo (p < 0.001). The regression equations for the least-squares fit to the area (y) against time (x) data points were y = 43.46-3.181x (r = -0.995) for ketanserin and y = 39.46-2.016x (r = -0.999) for placebo (p < 0.01). The 95% confidence limits for slopes were -3.181 +/- 0.98 and -2.016 +/- 0.15. Thus, average daily reduction in ulcer area was 4.5 mm2/day for ketanserin vs. 2.88 mm2/day for placebo. In conclusion, topical ketanserin significantly accelerated wound healing in diabetic neurotrophic foot ulcers when applied as part of a comprehensive healing program.
Possible Mechanism of Adenovirus Generation from a Cloned Viral Genome Tagged with Nucleotides at Its Ends (2006)

The entire cloned human adenovirus type 5 (Ad5) genome is known to be able to generate infectious virus after transfection into 293 cells when the both ends of the genome are exposed by digestion with appropriate restriction enzymes. However, when one or both ends of the genome are tagged with nucleotides and are not intact, whether the tagged end of the viral genome was remained tagged or corrected to be intact during the generation of viral clones has been unclear and, if such oligonucleotide removal occurs, how does the virus remove these tagged sequences and thereby restore its proper structure? Here, we show in our semi-quantitative study that the generation efficiency of virus clones decreases depending on the length of nucleotide tags at the both ends and that both the oligonucleotide tags were precisely removed during virus generation with restoration of the proper terminal sequences. Interestingly the viral genome of which one end was tagged, while the other was attached about 12-kb sequences, did generate intact viral clones at a reduced but significant efficiency. From these results, we here propose a possible mechanism whereby the terminal-protein-deoxycytidine complex enters from the enzyme-cleaved end and reaches deoxyguanine at the initiating position of DNA synthesis in vivo. A replication origin at one end, embedded deeply in double-stranded DNA, can be activated by two cycles of one-directional full-length DNA synthesis initiated by the other exposed replication origin about 30 kilobases away. We also describe new cassette cosmids which can use not only Pac I but also Bst BI for construction of an adenovirus vector, without reducing construction efficiency.
Lessons Learned From the 1970s Experiments in Solid Waste Conversion Technologies (2009)

Countless proposals for conversion technologies applied to municipal solid waste (MSW), such as gasification, many of which include mechanical processing of the MSW prior to the thermal conversion steps, have generated significant interest and press over the past few years. Many community groups and local officials are being pressured by developers to view these technologies as better and more politically acceptable alternatives to mass burn waste-to-energy facilities. From a historical perspective, most (but not all) of the basic technologies being promoted today are not new, but are variations of technologies that were evaluated and tested during the 1970s for use in processing and converting MSW. This paper presents overviews and several case studies of the MSW conversion technologies that were developed and tested during the 1970s including MSW processing and gasification technologies, and sets forth: • Lessons learned from those experiments. • Based upon the lessons learned, recommended rules of engagement for those contemplating evaluation or use of a processing and/or conversion technology. • A practical application of the above lessons learned and rules of engagement to the plasma arc gasification technology currently being promoted by a number of developers. The contents of this paper should be carefully considered by anyone contemplating the merits and feasibility of any MSW processing and/or conversion technology being promoted today or in the future.
Systemic Lidocaine Therapy for Poststroke Pain (1993)

Poststroke pain syndrome is commonly regarded as an intractable disease. We describe four patients who responded to an intravenous lidocaine infusion for relief of central pain after a stroke. The infusion was administered over a 48-hour period after an initial bolus of 50 to 100 mg intravenously over 40 to 120 seconds. Pain intensity and pain relief were measured by visual analog and numeric scales. All patients reported some relief within the first 12 hours of infusion. All patients were subsequently given a trial of mexiletine, an oral congener of lidocaine. Two have continued taking the drug and report excellent relief at 12 months' follow-up; the other two had side effects that precluded further use of the drug. We conclude that lidocaine can reduce poststroke pain, and we propose a treatment algorithm based on our experience with 40 additional patients treated for other neuropathic pain states.
Measurement of β‐Adrenergic Receptors on Lymphocytes in Normal Subjects and Asthmatics in Relation to β‐Adrenergic Hyperglycaemic Response and Bronchial Responsiveness (1983)

The numbers of beta-adrenergic receptors on lymphocytes in normal subjects and asthmatic patients were measured by the use of [125I]hydroxybenzylpindolol. The numbers of beta-adrenergic receptors per lymphocyte in normal subjects, drug-free asthmatics and patients taking beta-stimulants were 1146 +/- 98, 845 +/- 114 and 582 +/- 47 sites/cell (mean +/- SE), respectively. The differences were statistically significant (P less than 0.05) among these groups, while no statistically significant differences were found in dissociation constants. A 42% decrease in the number of beta-adrenergic receptors per lymphocyte after administration of 6 mg/day of terbutaline for 7 days was noted in four volunteers. There was significant correlation (r = 0.68, P less than 0.01) between the number of beta-adrenergic receptors per lymphocyte and the percentage increase in blood sugar 20 min after subcutaneous injection of 4 micrograms/kg epinephrine. There was also significant correlation (r = 0.78, P less than 0.005) between the number of beta-adrenergic receptors per lymphocyte and the respiratory threshold for acetylcholine. These results suggest that beta-blockade and bronchial hypersensitivity in asthmatic patients may in part be due to a decreased number of beta-adrenergic receptors.
A high-speed and highly uniform submicrometer-gate BPLDD GaAs MESFET for GaAs LSIs (1992)

The authors present formation conditions for ion-implanted regions of a GaAs buried p-layer lightly doped drain (BPLDD) MESFET that can improve short-channel effect, V/sub th/ uniformity, and FET operating speed, simultaneously. For 0.7- mu m gates, a Mg/sup +/ dose of 2*10/sup 12/ cm/sup -2/ at 300 keV and a Si/sup +/ dose of 2*10/sup 12/ cm/sup -2/ at 50 keV are suitable for the p layer and n' layer, respectively. A sigma V/sub th/ of 7 mV is realized. Gate-edge capacitance of the 0.7- mu m-gate BPLDD that consists of both overlap capacitance and fringing capacitance is successfully reduced to 0.5 fF/ mu m, which is about 50% of that of a non-LDD buried p-layer (BP) FET. Another parasitic capacitance due to the p-layer was found to have less effect on the speed than the gate-edge one. Consequently, the gate propagation delay time of the BPLDD can be reduced to 15 ps at power dissipation of 1 mW/gate, which is about 65% of that of a BP. Applying the 0.7- mu m-gate BPLDD to 16-kb SRAMs, the authors have obtained a maximum access time of less than 5 ns with a galloping test pattern.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A Preliminary Analysis of the Dental Informatics Literature (2003)

Dental informatics is an emerging discipline applying computer and information science to dental practice, research, education, and management. To date, the dental informatics research literature has not been comprehensively reviewed. This study reports an initial analysis of the dental informatics literature. We developed an initial, comprehensive retrieval strategy to locate dental informatics citations in MEDLINE (1966-April 2003), including three concepts: dentistry, computers, and research. After refinement of the search, we manually classified the final set into four categories: (1) non-dental; (2) dental, but neither dental informatics nor IT-related; (3) dental informatics; and (4) IT in dentistry. We analyzed informatics and IT-related citations regarding their distribution across journals, growth rate, the number of authors and their publication frequency, and content as expressed by Medical Subject Headings (MeSH). The final set of citations (n = 3872) consisted of: 12% non-dental articles; 59% dental, but not informatics- or IT-related articles; 16% informatics-related articles; and 13% IT-related articles. Informatics-related citations appeared in 176 journals, and IT-related citations in 206 journals. Approximately 50 papers are currently published in both categories yearly. While a great many authors have contributed to this literature, very few have published more than three papers. Main topics of articles included "Imaging and Image Processing", "Computer-aided Diagnosis and Therapy", "Computer-aided Instruction", and "Other". The dental informatics literature is small, but growing. Imaging and image processing predominate as research topics.
Semi-Solid State Printer (2013)

Printer is one of the important output devices, which is used widely. The existing ones are bulky and relatively slow thus require more printing time (ppm), which is due to the moving mechanical parts and mechanical constrains. In this new idea, the array of piezoelectric actuators, in the form of layer is used to provide impact on a paper containing carbonic paper in between. This impact results in the deposition of loosely bound ink, of carbon paper, to deposit on the blank sheet. In this approach, the printing time can be minimized to a few milliseconds, because of the quick response time of the actuator. The thickness of the semi-solid state printer can be as low as few millimetres. The length and width can be customized as per the size of paper. In brief, it can be proved as extremely thin, incredibly fast and silent printer.
The Safety, Efficacy and Compliance of Terazosin Therapy for Benign Prostatic Hyperplasia (1992)

The primary objective of the present interim analysis of an open label study initiated in December 1988 is to provide further insight into the long-term safety, efficacy and compliance of terazosin, a long-acting selective alpha 1-blocker, for the treatment of symptomatic benign prostatic hyperplasia (BPH). A total of 45 normotensive patients with symptomatic BPH was enrolled into this study. The dose of terazosin was titrated to 5 mg. during a 1-month period provided adverse reactions and orthostatic hypotension were not observed. The subjects were maintained on 5 mg. terazosin throughout the 24-month followup. The peak and mean urinary flow rates, obstructive and irritative Boyarsky symptom scores, and systolic and diastolic blood pressures were evaluated at 2, 6, 12, 18 and 24 months after initiation of therapy. Of the 45 subjects 21 (47%) exhibited a durable clinical response with no significant adverse events during the 24-month followup. The obstructive and irritative symptom scores decreased by 63% and 35%, respectively, after 2 months of terazosin therapy. These improvements in obstructive and irritative symptom scores were maintained throughout the 2-year followup. The peak and mean urinary flow rates improved by 42% and 48%, respectively, after 2 months of terazosin therapy. The changes in mean urinary flow rate increased, whereas the changes in peak urinary flow rate decreased during followup. Of the patients 6 (13%) were withdrawn from the study due to an adverse event. Our study demonstrates the safety, efficacy and compliance of terazosin therapy for BPH during a 2-year followup.
The αvβ3 integrin as a therapeutic target for inhibition of bone resorption (2004)

The Bone and Joint Monitor Project was developed to quantify the global burden of musculoskeletal conditions and develop strategies for their prevention. Experts within the Monitor Project have worked previously with officers at the World Health Organization (WHO) to estimate morbidity and mortality associated with rheumatic conditions. The present collaboration seeks means of providing additional and more current burden data. Objective To develop recommendations for performing epidemiological studies in sample populations with musculoskeletal conditions and problems, accounting for determinants and consequences to the individual and society. Methods Recommendations have been developed identifying the most relevant domains for measuring and monitoring the various musculoskeletal conditions by review of epidemiological data on occurrence, determinants and outcomes, and by expert opinion. Instruments that measure these domains were reviewed.
Antimicrobial effect of the extracts from <i>Hypericum perforatum</i> against oral bacteria and biofilm formation (2015)

According to the results, we suggest that H. perforatum could be employed as a natural antibacterial agent in oral care products.
Antimicrobial Activities of Novel Mannosyl Lipids Isolated from the Biocontrol Fungus <i>Simplicillium lamellicola</i> BCP against Phytopathogenic Bacteria (2014)

The antagonistic fungus Simplicillium lamellicola BCP has been developed as a microbial biopesticide that effectively controls the development of various plant diseases caused by both pathogenic bacteria and pathogenic fungi. Antibacterial bioassay-directed fractionation was used to isolate mannosyl lipids from S. lamellicola BCP, and the structures of these compounds were elucidated using spectral analysis and chemical degradation. Three novel mannosyl lipids were characterized and identified as halymecins F and G and (3R,5R)-3-O-β-D-mannosyl-3,5-dihydrodecanoic acid. Massoia lactone and (3R, 5R)-3-hydroxydecan-5-olide were also isolated from S. lamellicola BCP. The three novel compounds inhibited the growth of the majority of phytopathogenic bacteria that were tested, and halymecin F displayed the strongest antibacterial activity. Agrobacterium tumefaciens was the most sensitive to the three novel compounds, with IC₅₀ values ranging from 1.58 to 24.8 μg/mL. The ethyl acetate extract of the fermentation broth from the antagonistic fungus effectively reduced the bacterial wilt caused by Ralstonia solanacearum on tomato seedlings. These results indicate that S. lamellicola BCP suppresses the development of plant bacterial diseases through the production of antibacterial metabolites.
Tea Catechin Suppresses Adipocyte Differentiation Accompanied by Down-regulation of PPARγ2 and C/EBPα in 3T3-L1 Cells (2004)

Obesity is a serious health problem, and its prevention is promoted through life style including diet and exercise. In this study, we investigated the suppressive effects of tea catechin on the differentiation of 3T3-L1 preadipocytes to adipocytes. (-)-Catechin 3-gallate (CG), (-)-epigallocatechin (EGC), (-)-epicatechin 3-gallate, and (-)-epigallocatechin 3-gallate at 5 muM suppressed intracellular lipid accumulation. The suppressive effects of CG and EGC were stronger than the others, and CG and EGC also suppressed the activity of glycerol-3-phosphate dehydrogenase as a differentiation marker. These catechins inhibited the expression of peroxisome proliferator-activated receptor (PPAR) gamma2 and CCAAT/enhancer-binding protein (C/EBP) alpha, both of which act as key transcription factors at an early stage of differentiation, followed by the expression of glucose transporter (GLUT) 4 at a later stage. In addition, the catechins did not affect the phosphorylation status of the insulin signal pathway. Thus, catechin suppressed adipocyte differentiation accompanied by the down-regulation of PPARgamma2, C/EBPalpha, and GLUT4. These results suggest that tea catechin prevents obesity through the suppression of adipocyte differentiation.
