Characterization of a DNA uptake reaction through the nuclear membrane of isolated yeast nuclei (1988)

Isolated yeast nuclei were able to incorporate 3H-labeled pJDB219 DNA in vitro in the presence of ATP and Mg2+. The number of plasmid molecules incorporated into each nucleus was calculated to be 60 under the conditions we used. Enzyme-histochemical staining of the incorporated biotinylated pJDB219 with streptavidin-biotinylated-peroxidase complex indicated a uniform distribution of the incorporated plasmids within each nucleus. After intranuclear incorporation, substrate pJDB219 DNAs (open and closed circular forms) were changed to the linear form and were weakly digested over the longer incubation period (over 60 min). Facile release of the once-incorporated plasmid DNA was never observable; discharge of the incorporated [3H]pJDB219 during a 60-min incubation was less than 5%. The addition of adenylyl-imidodiphosphate, N,N'-dicyclohexylcarbodiimide (DCCD), or quercetin inhibited in vitro DNA uptake reaction. DCCD and quercetin inhibited the nuclear ATPase and apparent protein kinase, respectively; hence, the involvement of these enzymes in the nuclear DNA transport system was suggested.
Novel control techniques for three-phase three-wire series-parallel compensated line-interactive UPS system (2004)

A three-phase three-wire series-parallel compensated line-interactive UPS consisting of two voltage-source converters controlled separately by two digital signal processors is studied in this paper. The series converter can be controlled as non-sinusoidal voltage source as series active power filter to compensate harmonic voltage at the utility, while the parallel converter can be controlled as non-sinusoidal current source as shunt active power filter to compensate reactive and harmonic currents deriving from inductive and non-linear loads. However, controlling the series converter as fundamental sinusoidal current source and the parallel converter as fundamental sinusoidal voltage source is a much better choice for this kind of system to facilitate the transition from stand-by to back-up mode or vice versa. Additionally, state feedback decoupling terms are used in the current regulator of the series converter to reduce the response time, while repetitive controllers are plugged in the voltage regulator of the parallel converter to reduce steady-state errors and distortion caused by unknown periodic disturbances. Both algorithms are based on the synchronous rotating frame and implemented respectively by two digital signal processors. These novel control techniques are proposed firstly for this kind of UPS and are verified by detailed experimental results.

Coding theory of designs (1981)

The amount of information which coding theory gives about a design can vary enormously from one design to another. As it is now known that a plane of order 10 can have only the identical collineation, its binary code is now our main source of information on it.

Research on Influence of the Engine Air Filter Replacement Periodicity (2011)

The study evaluates current periodicity of engine air filter replacement to determine the influence of this operation on some vehicle performance parameters. The experience of usage, costs of exploitation and technical condition of the vehicle are connected with a technically and economically based system of technical servicing. Periodicity of motor air filter replacement, declared by the automobile manufacturer Renault ranges from 30 000 km to 120 000 km, depending on the model and en gine type. According to the same recommendations, periodicity must be reduced by a half, if conditions of use include dusty roads and exploitation of the vehicle in urban conditions. The aim of the research is to evaluate the criteria, according to which actual replacement of motor air filters was performed and to measure the influence of air filters with different levels of use on the engine performance. To reach the goal, air filter cartridges from 100 vehicles of the same model and type, which were used in Latvia were collected. The influence of air filter clogging on several vehicle exploitation parameters, such as engine power and fuel consumption was analyzed. The value of maximum permissible pressure difference before and after the air filter was determined. Air filters, collected from vehicles, were tested on the test bench for the value of air pressure difference. The results obtained with all the samples have been presented and critically examined.
Synthesis of Magnetic, Up‐Conversion Luminescent, and Mesoporous Core–Shell‐Structured Nanocomposites as Drug Carriers (2010)

Abstract The synthesis (by a facile two‐step sol–gel process), characterization, and application in controlled drug release is reported for monodisperse core–shell‐structured Fe 3 O 4 @ n SiO 2 @ m SiO 2 @NaYF 4 : Yb 3+ , Er 3+ /Tm 3+ nanocomposites with mesoporous, up‐conversion luminescent, and magnetic properties. The nanocomposites show typical ordered mesoporous characteristics and a monodisperse spherical morphology with narrow size distribution (around 80 nm). In addition, they exhibit high magnetization (38.0 emu g −1 , thus it is possible for drug targeting under a foreign magnetic field) and unique up‐conversion emission (green for Yb 3+ /Er 3+ and blue for Yb 3+ /Tm 3+ ) under 980 nm laser excitation even after loading with drug molecules. Drug release tests suggest that the multifunctional nanocomposites have a controlled drug release property. Interestingly, the up‐conversion emission intensity of the multifunctional carrier increases with the released amount of model drug, thus allowing the release process to be monitored and tracked by the change of photoluminescence intensity. This composite can act as a multifunctional drug carrier system, which can realize the targeting and monitoring of drugs simultaneously.
New Evidence on the Size and Possible Effects of a Late Pliocene Oceanic Asteroid Impact (1988)

Debris from a late Pliocene asteroid impact is spread across at least 600 kilometers of the ocean floor in the southeast Pacific. On the basis of iridium concentrations in sediments from six deep-sea cores, the asteroid diameter was at least 0.5 kilometer; the impacting projectile may have been one of the largest in the last few million years. The stratigraphic age of this impact is the same as that inferred for the onset of Northern Hemisphere glaciation.
Design and characterization of a programmable step generator with very fast settling performance (1987)

A pulse generator for testing the step response of waveform recorders is described. The initial and final levels of voltage steps are each programmable within the range of ± 1 V for a 50-Ω termination. Voltage steps within this range settle to within ±0.2 and ±0.1 percent of full-scale range (FSR) in approximately 4 and 6 ns, respectively. The 10–90 percent transition duration (T <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">R</inf> ) is approximately 1.7 ns.
After more than a century, iron sponge still soaks up hydrogen sulfide problems (1994)

The oldest and simplest method for removing H[sub 2]S and other sulfur compounds, such as mercaptans, from gaseous streams is the iron sponge process. The basic technique consists of passing a sour gas stream (one containing H[sub 2]S or mercaptans, or both) across a bed of hydrated iron oxide. The chemical reaction produces iron sulfide and a small amount of by-product water. Although not a common practice, the spent material may be regenerated by exposing it to oxygen, which converts the mixed iron sulfides to their original iron oxide form. The iron sponge technique originated in Europe more than 100 years ago, and the earliest operators used a naturally occurring form of hydrated iron oxide known as bog iron or bog ore. As refinements were made in the process, it was found that more efficient sulfur removal could be attained by uniformly distributing the iron oxide hydrate across a substrate, and that active iron oxide could be prepared synthetically. Continual improvements in the synthetic iron sponge's composition focused on such issues as the crystalline forms of the hydrated iron oxide, size distribution of the active iron oxide particulates, overall chemical composition, size and nature of the typical wood substrate, moisturemore » content, and degree of buffering. Modern iron sponge products are prepared with careful attention to each of these issues. The synthetic materials are characterized by high quality and uniform composition, and their overall characteristics optimize performance in typical gas-sweetening applications.« less
Comparative Study Between the Effects of Photodynamic Therapy and Conventional Therapy on Microbial Reduction in Ligature‐Induced Peri‐Implantitis in Dogs (2005)

Research on Anonymization and De-anonymization in the Bitcoin System (2015)

The Bitcoin system is an anonymous, decentralized crypto-currency. There are some deanonymizating techniques to cluster Bitcoin addresses and to map them to users' identifications in the two research directions of Analysis of Transaction Chain (ATC) and Analysis of Bitcoin Protocol and Network (ABPN). Nowadays, there are also some anonymization methods such as coin-mixing and transaction remote release (TRR) to cover the relationship between Bitcoin address and the user. This paper studies anonymization and de-anonymization technologies and proposes some directions for further research.
A quaternion-based orientation estimation algorithm using an inertial measurement unit (2004)

This paper presents a real-time orientation estimation algorithm based on signals from a low-cost inertial measurement unit (IMU). The IMU consists of three MEMS accelerometers and three MEMS rate gyros. This approach is based on relationships between the quaternion representing the platform orientation, the measurement of gravity from the accelerometers, and the angular rate measurement from the gyros. Process and measurement models are developed, based on these relations, in order to implement them into an extended Kalman filter. The performance of each filter is evaluated in terms of the roll, pitch, and yaw angles. These are derived from the filter output since this orientation representation is more intuitive than the quaternion representation. Extensive testing of the filters with simulated and experimental data show that the filters perform very accurately in the roll and pitch angles, and even significantly corrects the yaw angle error drift.

Multiwavelength depth encoding method for 3D range geometry compression (2015)

This paper presents a novel method for representing three-dimensional (3D) range data within regular two-dimensional (2D) images using multiwavelength encoding. These 2D images can then be further compressed using traditional lossless (e.g., PNG) or lossy (e.g., JPEG) image compression techniques. Current 3D range data compression methods require significant filtering to reduce lossy compression artifacts. The nature of the proposed encoding, however, offers a significant level of robustness to such artifacts brought about by high levels of JPEG compression. This enables extremely high compression ratios while maintaining a very low reconstruction error percentage with little to no filtering required to remove compression artifacts. For example, when encoding 3D geometry with the proposed method and storing the resulting 2D image with Matlab R2014a JPEG80 image compression, compression ratios of approximately 935:1 versus the OBJ format can be achieved at an error rate of approximately 0.027% without any filtering.
The cultural making of the citizen: a comparative analysis of school students’ civic and political participation in France and Wales (2020)

This paper examines the complex relationship between the state, civil society and education through comparative research with young people in France and the UK. Survey data derived from two cohorts of school students in South Wales and Lyon reveal strong differences in their levels of civic and political participation. While our Welsh students have higher levels of ‘civic participation’, as measured in terms of charitable work and volunteering, our French students have far higher levels of what might be considered ‘political engagement’, defined in terms of campaigning and demonstrating. We argue that these differences can be accounted for by the different cultural repertoires and priorities of citizenship education which themselves reflect the contrasting historical configurations of education, the state and civil society in these two countries.
Identification of Mycobacterium tuberculosis and M. avium complex directly from smear-positive sputum specimens and BACTEC 12B cultures by high-performance liquid chromatography with fluorescence detection and computer-driven pattern recognition models (1995)

A high-performance liquid chromatography method that utilized fluorescence detection (HPLC-FL) of mycolic acid 6,7-dimethoxycoumarin esters was developed to identify Mycobacterium tuberculosis (MTB) and M. avium complex (MAC) directly from fluorochrome stain smear-positive sputum specimens and young BACTEC 12B cultures. HPLC-FL chromatograms from a training set that included 202 smear-positive clinical sputum specimens and 343 mycobacterial cultures were used to construct a calibrated peak-naming table and computer-based pattern recognition models for MTB and MAC. Pattern recognition model performance was measured with an evaluation set of samples that included 251 smear-positive clinical sputum specimens and 167 BACTEC 12B cultures. Evaluation sputum specimens were culture positive for MTB (n = 132) and MAC (n = 48). With evaluation sputa, the MTB and MAC models were 56.8 and 33.3% sensitive, respectively. Evaluation set BACTEC 12B cultures were culture positive for MTB (n = 97) and MAC (n = 53). The sensitivities of the MTB and MAC models for identification of BACTEC 12B cultures were 99.0 and 94.3%, respectively. The specificity of both models was 100% for both types of evaluation samples. The average times from BACTEC 12B inoculation to cell harvest were 10.2 and 7.4 days for MTB and MAC, respectively. HPLC-FL can identify MTB and MAC in 1 day from many smear-positive sputa. Rapid and sensitive identification of MTB and MAC from young BACTEC 12B cultures was achieved.
Photoluminescence of InAs1−xSbx/AlSb single quantum wells: Transition from type-II to type-I band alignment (2000)

Infrared photoluminescence has been used to study the band-gap energy of InAs1−xSbx digital superlattices and band alignment of InAs1−xSbx/AlSb quantum wells at 5 K. It is found that the InAs1−xSbx digital alloys have a smaller effective band gap than InAs1−xSbx random alloys. In addition, the valence band offset between type-II InAs/AlSb is determined to be 130 meV. This number reduces as the Sb mole fraction in InAs1−xSbx is increased, and the alignment between InAs1−xSbx/AlSb becomes type I when x&gt;0.15.
Mirtazapine: An Antidepressant with Noradrenergic and Specific Serotonergic Effects (1997)

Mirtazapine is a unique antidepressant that refines the specificity of effects on noradrenergic and serotonergic systems. It is an antagonist of presynaptic alpha 2-adrenergic autoreceptors and heteroreceptors on both norepinephrine and serotonin (5-HT) presynaptic axons, plus is a potent antagonist of postsynaptic 5-HT2 and 5-HT3 receptors. The net outcome of these effects is increased noradrenergic activity together with specific increased serotonergic activity, especially at 5-HT1A receptors. This mechanism of action maintains equivalent antidepressant efficacy but minimizes many of the adverse effects common to both tricyclic antidepressants and selective serotonin reuptake inhibitors. Mirtazapine has an onset of clinical effect in 2-4 weeks similar to other antidepressants, although sleep disturbances and anxiety symptoms may improve in the first week of treatment. It has minimal cardiovascular and anticholinergic effects, and essentially lacks serotonergic effects such as gastrointestinal symptoms, insomnia, and sexual dysfunction. Sedation, increased appetite, and weight gain are more common with mirtazapine than with placebo. An elimination half-life of 20-40 hours enables once-daily bedtime dosing. The recommended initial dosage is 15 mg once/day at bedtime, with an effective daily dosage range of 15-45 mg. Cases of overdose of up to 975 mg caused significant sedation but no cardiovascular or respiratory effects or seizures.

Conventional treatment of idiopathic nephrotic syndrome and membranous nephropathy in adults. (1991)

This article is a review of the results of corticosteroid and immunosuppressive treatment in adults with idiopathic nephrotic syndrome. Adults with minimal-change nephropathy usually require a prolonged administration of corticosteroids to achieve remission which, in itself, carries the risk of severe and even life-threatening complications. Therefore, intravenous high-dose steroid pulses, alternate-day prednisone, short courses with cytotoxic agents and long-term administration of azathioprine have been suggested as alternatives to the classical prolonged corticotherapy. While most patients with focal-segmental glomerulosclerosis do not respond to short-term prednisone, almost half of the patients with nephrotic syndrome will attain remission with a more prolonged administration of corticosteroids and/or cytotoxic agents. A six-month course of methylprednisolone and chlorambucil preserves renal function and reduces the proteinuria in many patients with membranous nephropathy, even in the presence of initial renal insufficiency. Thus, there is growing evidence that corticosteroids and/or immunosuppressive agents can favorably alter the natural course of disease in many patients with idiopathic glomerulonephritis. However, these agents have a low therapeutic index. Further studies are needed to find more effective and less toxic treatment approaches in patients with primary glomerulonephritis.

This paper reports the first demonstration of nuclear orientation of radioactive xenon atoms by spin exchange with polarized rubidium atoms. The nuclear tensor alignment, as measured by gamma-ray anisotropy, is about 30% of the maximum possible. The magnetic dipole moments for $^{133}\mathrm{Xe}$, $^{133}\mathrm{Xe}^{m}$, and $^{131}\mathrm{Xe}^{m}$ have also been measured by NMR spectroscopy. The methods developed here have possibilities for wide applications to nuclear and atomic studies of other radioactive rare-gas atoms.
