Efficacy of non-purine and purine cytokinins on shoot regeneration in vitro in sugarcane (2009)

Effect of two non-purine cytokinins, TDZ [N-phenyl-N′ - (1,2,3-thidiazol-5-yl) urea] and 4-CPPU [N- (2-chloro-4pyridyl) N-phenylurea] and meta-topolin [6 (3-hydroxybenzylamino) purine] a biologically active aromatic compound, on shoot regeneration in sugarcane var. CoS 8436 and Co 1148 and S. officinarum clone ‘Gungera’ was observed at 15, 25 and 35 d. 4-CPPU significantly enhanced shoot regeneration in var. CoS 8436, but showed no effect or caused only a slight promotion in var. Co 1148 and clone ‘Gungera’. Meta-topolin was most effective in promoting shoot regeneration at 5 µ M in var CoS 8436, at 1 µ M in var Co 1148 and at 10 µ M in in clone Gungera. The best response to TDZ was observed at 0.01 µM in vars CoS 8436 and Co 1148 and at 0.1 µ M in clone Gungera. Thus, there was a clear varietal response of sugarcane to these chemicals. Clone ‘Gungera’ responded best to meta-topolin, CoS 8436 to 4-CPPU and Co 1148 to TDZ. Results obtained in this work clearly demonstrate TDZ induced shoot regeneration in sugarcane at unusually low concentration, such as 0.01 µ M and 0.1 µ M. Further, 4-CPPU, meta-topolin and TDZ simulate cytokinin activity and may thus provide a better substitute of cytokinins like BAP or Kn that are generally used in tissue culture.
Variability of photoplethysmographyperipheral pulse measurementsat the ears, thumbs and toes (2000)

Pulses radiating to the periphery after each heart beat can be detected by photoplethysmography (PPG). A multi-site PPG measurement and analysis system is described for beat-to-beat analysis of the pulse waveforms. Waveforms were collected from the right and left ear lobes, thumb pads, and toe pads of 20 normal subjects whilst they performed paced breathing. The median coefficients of variation for pulse amplitude were; ears and thumbs 11%, and toes 14%. Significant differences in pulse transit time of 4 ms (to foot of pulse), and 14 ms (to peak of pulse) between the right and left toes were detected (right lagging left, p < 0.01). The median pulse transit times (to foot) were; ears (0.133 s), thumbs (0.199 s), and toes (0.301 s), with coefficients of variation; 2.8%, 2.2%, and 1.6%, respectively. The median pulse transit times (to peak) were; ears (0.397 s), thumbs (0.436 s), and toes (0.515 s), with coefficients of variation; 1.4%, 2.0%, and 1.5%, respectively. The authors have utilised signal processing algorithms to calculate beat-to-beat measures of pulsatility, and determined normative data for multi-site PPG pulse assessments.
Pharmacokinetics of Tigecycline after Single and Multiple Doses in Healthy Subjects (2004)

Tigecycline, a novel glycylcycline antibiotic, exhibits strong activity against gram-positive, gram-negative, aerobic, anaerobic, and atypical bacterial species, including many resistant pathogens, i.e., vancomycin-resistant enterococci, methicillin-resistant Staphylococcus aureus and penicillin-resistant Streptococcus pneumoniae. The safety and tolerability of tigecycline administered as single or multiple doses or at various infusion rates were explored in three phase 1, randomized, double-blind, placebo-controlled studies in healthy subjects. Full pharmacokinetic profiles of tigecycline were determined in two of these studies. Subjects in the single-dose study received 12.5 to 300 mg of tigecycline, which differed with respect to the duration of infusion, subjects' feeding status, and ondansetron pretreatment. Subjects in the ascending multiple-dose study received 25 to 100-mg doses of tigecycline as a 1-h infusion every 12 h. The variable volume and infusion rate study consisted of administration of 100-mg loading dose of tigecycline, followed by 50 mg every 12 h for 5 days. Serum samples were analyzed for tigecycline by validated high-pressure liquid chromatography or liquid chromatography/tandem mass spectrometry methods. Systemic clearance ranged from 0.2 to 0.3 liters/h/kg, and the tigecycline half-life ranged from 37 to 67 h. Tigecycline had a large volume of distribution (7 to 10 liters/kg), indicating extensive distribution into the tissues. Food increased the maximum tolerated single-dose from 100 to 200 mg, but the duration of infusion did not affect tolerability. Side effects, mainly nausea and vomiting, which are common to the tetracycline class of antimicrobial agents, were seen in these studies. Tigecycline exhibits linear pharmacokinetics and is safe and well tolerated in the dose ranges examined.
Multichannel blind deconvolution of arbitrary signals: adaptive algorithms and stability analyses (2002)

We derive three computationally-efficient algorithms for the multichannel blind deconvolution of arbitrary non-Gaussian source mixtures. Two of the algorithms are spatio-temporal extensions of previously-derived blind signal separation algorithms that combine kurtosis-based contrast function optimization with output whitening. We analyze the local stability properties of the algorithms to determine the constraints on the step sine parameters to allow the separation and deconvolution of arbitrary signal mixtures. These analyses and supporting simulations illustrate the abilities of the new algorithms to effectively deconvolve and separate mixtures of arbitrarily-distributed sources.
New methods for improving the dyeability of cellulose fibres with reactive dyes* (1991)

Cellulose fibres may be dyed with reactive dyes in the absence of added electrolyte under neutral to slightly acidic conditions provided the fibre is modified to include cationic sites. The effect of amine substitution has been examined in detail using the activated substrate prepared by the reaction of cotton with N‐methylolacrylamide. Dyes containing pendant aliphatic amino groups were also prepared and their reactivity towards the pre‐activated cotton substrate assessed.
Real time facial expression recognition app development on mobile phones (2016)

Facial expression has made significant progress in recent years with many commercial systems are available for real-world applications. It gains strong interest to implement a facial expression system on a portable device such as tablet and smart phone device using the camera already integrated in the devices. It is very common to see face recognition phone unlocking app in new smart phones which are proven to be hassle free way to unlock a phone. Implementation a facial expression system in a smart phone would provide fun applications that can be used to measure the mood of the user in their daily life or as a tool for their daily monitoring of the motion in phycology studies. However, traditional facial expression algorithms are normally computing extensive and can only be implemented offline at a computer. In this paper, a novel automatic system has been proposed to recognize emotions from face images on a smart phone in real-time. In our system, the camera of the smart phone is used to capture the face image, BRIEF features are extracted and k-nearest neighbor algorithm is implemented for the classification. The experimental results demonstrate that the proposed facial expression recognition on mobile phone is successful and it gives up to 89.5% recognition accuracy.
An information protection system for intranets (2003)

With the widespread use of the Internet and intranets, it is becoming more and more important for us to protect information and intellectual property rights of corporations. This paper describes the shortcomings of traditional security technologies and presents an information protection system for intranets. The system includes four components that are data collection, policy management, data analysis and data presentation. The system uses the Latent Semantic Indexing to analyze the information flowing between the intranet and public networks. The system detects and stops information which is not permitted to be transmitted. Experimental results show that the system carries out the analysis accurately as well as efficiently. The system provides an effective solution to protecting information in an intranet environment.
A new approach for an embedded Wi-Fi controller in a C band phased array antenna (2009)

Modern phased array antennas in radar systems are composed of several thousands of transmit/receive modules (TRM). Performance of radars are strongly related to the correct functioning of the control chain for such modules. It is therefore fundamental to perform diagnostic and monitoring of main characteristics of active array components; in this way, system performance may be checked and, if necessary, suitable actions to guarantee them may be actuated.
Measurement of Antipyretic Activity of Ibuprofen and Paracetamol in Children (1980)

The antipyretic activity of ibuprofen (Brufen) and paracetamol (Crocin) was compared in 22 children with pyrexia who received either ibuprofen or paracetamol in syrup form. Both axillary and rectal temperatures were recorded prior to drug administration and 1/2, 1, 2, 3, 4, 5, 6, 8, and 12 hours after dosing. Analysis of the results in terms of rate of temperature decrease and degree and duration of decrease in temperature indicated that both drugs produced significant reduction in temperature and in the rate of temperature decrease. The maximum effect of the two drugs was similar. However, ibuprofen was more effective than paracetamol at 6 and 8 hours after administration, and its duration of action was longer. The associated antipyretic and antiinflammatory features of ibuprofen could provide an advantage in the control of exudative forms of upper respiratory tract infections.
Wide-band orthomode transducers (1991)

A summary of the results of a mainly experimental investigation into the development of wideband orthomode transducers (OMTs) is presented. It is shown that satisfactory performance for many applications is possible over bandwidths in excess of 2:1. The wideband return loss and cross-polarization behavior are given where the OMT used is measured in conjunction with a wideband corrugated horn. Two types of OMT are considered: one based on a finline technique and the other on a quad-ridged waveguide geometry. Overall, the latter design gives superior performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Free Lipase‐Catalyzed Esterification of Oleic Acid for Fatty Acid Ethyl Ester Preparation with Response Surface Optimization (2012)

Abstract Free lipase‐mediated alcoholysis for biodiesel production has drawn increasing attention in recent years due to its advantages of lower cost and faster reaction rate compared to immobilized lipase. Ethanol, derived from renewable biomass, has a great potential for biodiesel production. A previous study showed that free lipase NS81006 could effectively catalyze the ethanolysis of triglycerides for biodiesel preparation. Since most crude plant oils always contain an amount of free fatty acids, oleic acid was used as the model substrate for this study on lipase‐mediated esterification for biodiesel production. The central composite design of the response surface methodology was adopted for process optimization. A biodiesel yield of over 90 % was achieved under optimal reaction conditions and the repeated use of the free lipase was easily realized through phase separation either by natural gravity force or centrifugation.

SEPARATION OF ACETYL TRANSFER ENZYMES IN PIGEON LIVER EXTRACT (1952)

Pigeon liver extract has proved to be a store-house of biosynthetic and, particularly, acetylation reactions.Acetylation of arylamine (I), histamine (Z), and glucosamine (3) and the synthesis of acetoacetate (4) and of citrate (5) were found in this extract.In all these systems, acetate, coenzyme A (CoA), and adenosinetriphosphate (ATP) react with the various acetyl acceptors.From early data, it had become quite likely that acetate, CoA, and ATP reacted enzymatically to yield the common acetyl donor, which carried the acetyl to the various acceptors by way of more or less specific transfer enzymes (4, 6).A rigorous proof for this interpretation could be obtained only through a separation of the specific enzyme systems involved.Some preliminary progress had been made by fractionation with ammonium sulfate (7), but fractionation with acetone in the cold proved to be most successful for this purpose.A preliminary report of the results of these experiments was published previously (8). Analytical MethodsAcetylation of aromatic amines was determined by the method of Bratton and Marshall (9).Citrate was determined by the method of Krebs and Eggleston (10) as modified by Novelli and Lipmann (11).Determination of acet.oacetate was carried out by the salicylaldehyde method of Behre (12), by applying a microdiffusion technique similar to that described by Stadtman et al. ( 13).As a diffusion chamber, a 25 ml.Pyrex Erlenmeyer flask was used, into which a glass cup containing bisulfite was inserted.The glass cup was prepared by sealing 1.5 to 2 cm. of the lower end of a 13 X 100 mm.Pyrex test-tube to a Pyrex glass rod, 8 cm.long and 4 mm. in diameter.The glass rod was fitted tightly into a No. 1 rubber stopper and adjusted to leave about a 1 cm.space between the bottom of the cup and the fluid level. 1 to 2 ml. of the sample was placed in the bottom of the Erlenmeyer flask and 0.2 ml. of 15 N sulfuric acid was added.Immediately, the cup containing 0.4 ml. of M sodium bisulfite solution was inserted.The tightly stoppered flask was incubated for 12 to 16 hours at
Lanthanide Ions Doped CsPbBr<sub>3</sub> Halides for HTM‐Free 10.14%‐Efficiency Inorganic Perovskite Solar Cell with an Ultrahigh Open‐Circuit Voltage of 1.594 V (2018)

Abstract All‐inorganic cesium lead bromide (CsPbBr 3 ) perovskite solar cells have attracted enormous attention owing to their outstanding stability in comparison with organic–inorganic hybrid devices. The greatest weakness for inorganic CsPbBr 3 solar cells is their lower power conversion efficiencies, mainly arising from inferior light‐absorbance range and serious charge recombination at interfaces or within perovskite films. To address this issue, the lattice doping of lanthanide ions (Ln 3+ = La 3+ , Ce 3+ , Nd 3+ , Sm 3+ , Eu 3+ , Gd 3+ , Tb 3+ , Ho 3+ , Er 3+ , Yb 3+ , and Lu 3+ ) into CsPbBr 3 films for all‐inorganic solar cells free of hole‐transporting materials and precious metal electrodes is presented. Arising from the enlarged grain size and prolonged carrier lifetimes upon incorporating Ln 3+ ions into perovskite lattice, the performances of these inorganic CsPbBr 3 solar cell devices are significantly enhanced, achieving a champion efficiency as high as 10.14% and an ultrahigh open‐circuit voltage of 1.594 V under one sun illumination. Meanwhile, the nearly unchanged efficiency upon persistent attack by 80% RH in air atmosphere over 110 d and enhanced thermal stability at 80 °C over 60 d provide new opportunities of promoting commercialization of all‐inorganic CsPbBr 3 perovskite solar cells.
Epidemiology of idiopathic dilated and hypertrophic cardiomyopathy. A population-based study in Olmsted County, Minnesota, 1975-1984. (1989)

Using the records linkage system of the Mayo Clinic and of the Rochester Epidemiology Project, which accesses diagnostic data on the entire population of Olmsted County, Minnesota, we identified 45 new cases of idiopathic dilated cardiomyopathy (DCM) and 19 new cases of hypertrophic cardiomyopathy (HCM) among county residents for the years 1975-1984. Overall age- and sex-adjusted incidence rates were 6.0/100,000 and 2.5/100,000 person-years, respectively. The incidence of DCM doubled from 3.9/100,000 in the first 5 years to 7.9/100,000 person-years in the last 5 years of study. The corresponding change for HCM was from 1.4 to 3.6/100,000 person-years. Age- and sex-adjusted prevalence rates as of January 1, 1985, for DCM and HCM were 36.5/100,000 and 19.7/100,000 population, respectively. The prevalence of DCM in persons less than 55 years old was 17.9/100,000, over a third of whom were New York Heart Association functional Class III or IV at diagnosis. These estimates may be of value in determining the potential use of health care resources, particularly cardiac transplantation.
A class of SEC‐DED‐SBED codes for semiconductor memory (1985)

Abstract The SEC‐DED‐SbED code is capable of correcting a single‐bit eror, detecting a random double‐bit error and detecting a b‐bit block error. It is expected to be widely used for highly reliable semiconductor memory systems composed of memory devices with b‐bit output. In this paper a new theoretical construction method for SEC‐DED‐SbED codes is proposed. The proposed class of codes is so characterized that, with byte length b, it is constructed from conventional SEC‐DED‐SbED codes of byte length b/2 and the weight of the column vector of its parity check matrix H (the number of l's) is odd. The bit length n of the code is given as n _ b2(r‐b) . r/2Cb/2 bits, when the check bit length r and the byte length b are even. It has the longest bit length among the known code classes in a large range of byte lengths.
Exploratory assessment of a combined-cycle engine concept for aircraft propulsion (2017)

This preliminary study considers a combined cycle configu­ration for aeroengines, whereby thermal energy from the exhaust of the gas turbine is partly recovered in order to obtain additional mechanical power. The waste heat recovery system is based on a closed thermodynamic bottoming cycle with supercritical car­ bon dioxide (scCO2) as working fluid, allowing to achieve a very high power density. As first step of the investigation a thermo­dynamic cycle analysis of the combined-cycle engine (CCE) is carried out. Results are compared to those of the intercooled­recuperative engine (IRE) configuration for the same operating conditions and calculated under the same modeling assumptions. The estimated nominal SFC of the proposed CCE configuration is approximately 20% lower compared to that of a conventional turbofan, and 6% lower than that of the IRE, if pressure drops in the heat exchangers are neglected. Such large gain justified further analysis, by including the preliminary sizing of main components. Once the sizing of heat exchangers is factored in, the thermodynamic benefit of the CCE is offset by the penalty due to the weight of the additional equip­ment. This is mainly caused by i) the space constraints of the turbofan nacelle, which strongly limit the recoverable thermal power, and ii) the lack of proper het exchanger technology for such a highly unconventional application. These issues, and the many other that need consideration, will be addressed in an upcoming research project encompassing a much wider scope involving new aircraft and propulsion system
Migratable user interfaces:beyond migratory interfaces (2004)

The migration of a user interface (UI) is the action of transferring a UI from one device to another, for example from a desktop computer to a handheld device. A UI is said to be migratable if it has the ability to migrate. This paper describes how the QTk toolkit has been extended to provide a migratable UI and the application programming interface (API) provided to the developers. Basically, an indirection layer has been introduced between the application and the actual representation of the UI. The migration of a UI is achieved by firstly creating a clone of the state of the site displaying the UI, secondly by changing the indirection to point to this clone. The API provides a way to specify if (the entirety of) a window can be migrated or not at construction time. A migratable window returns a universal reference that can be given to any site with whom a network connection is possible. This reference can be used by a receiver widget to migrate the window there. Interestingly, a migratable window can itself contain a receiver widget configured to display the content of another migratable window: all windows are transparently migrated. Also a window (stationary or migratable) may contain one or more receiver widgets : it is possible to dynamically compose a Ul from several different UIs.
Testing of several distributed file-systems (HDFS, Ceph and GlusterFS) for supporting the HEP experiments analysis (2014)

The activity of testing new storage solution is of great importance in order to provide both features and performance evaluation and give few hints to small-medium sites that are interested in exploiting new storage technologies. In particular this work will cover storage solutions that provide both standard POSIX storage access and cloud technologies; we focused our attention and our test on HDFS, Ceph, and GlusterFS.
An implementation of NDIR type $CO_2$ gas sample chamber and measuring hardware for capnograph system in consideration of the time response characteristics (2001)

The capnograph system for determining the partial pressure of carbon dioxide in the blood of a patient was developed based on the NDIR(non-dispersive infrared) absorption technology. NDIR gas analyzing method requires an optical absorption chamber and signal processing hardware. In this paper, we have designed and implemented NDIR type gas chamber in consideration of the time response characteristics and lamp chopping frequency. And we have implemented signal processing hardware using two infrared sources to reduce the thermal background effect. The implemented gas chamber and signal processing hardware were tested in the temperature variation experiment and human expiratory experiment. The results showed that the system could produce a stable output signal and a good gas concentration curve like a typical capnogram.
