The modeling of characteristics of the patch antenna with non-uniform substrate metamaterial (2016)

Analysis of the effectiveness of metamaterials as a substrate of microstrip antennas for the purpose of providing broadband antenna while reducing the size and increasing the antenna gain are carried out in the report. As an example of the calculation of a microstrip antenna characteristics are given in which the substrate is a metamaterial unit cell in the form of nested open rings (SRR - split ring resonator). The resonant frequency of the resonator is determined by the length of the open rings, the size of the gap and the thickness of the rings. the basic laws of influence on the characteristics of microstrip antennas geometrical sizes of rings are obtained, the calculation results are summarized in the form of nomograms. The case of the planar antenna and conformal microstrip antenna located on a cylindrical surface is considered. Research are conducted by a specialized package FEKO.
Vibration analysis using symbolic computation software (1997)

This paper presents a general approach to modelling and learning vibration analysis for simple beams using symbolic computation software. The emphasis here is on the fact that a complete solution of the beam vibrations problem, for different boundary conditions and arbitrary forcing functions, is made very simple by using symbolic computation software. The heart of the procedure is to convert the beam vibration problem into a system of simultaneous algebraic linear equations and then use symbolic computation software to solve it. The analysis also shows how to obtain models suitable to design controllers for flexible systems.
Role of human Pso4 in mammalian DNA repair and association with terminal deoxynucleotidyl transferase (2003)

Terminal deoxynucleotidyl transferase (TdT; EC 2.7.7.31) adds nucleotides to DNA ends generated during V(D)J recombination that are subsequently processed by proteins involved in general double-strand break (DSB) repair pathways. We report an association between TdT and a 55-kDa protein in lymphoid cells. This protein, identified as hPso4, is a homolog of the protein encoded by the PS04/PRP19 gene in Saccharomyces cerevisiae that has pleiotropic functions in DNA recombination and error-prone repair. Purified hPso4 binds double-stranded DNA in a sequence-nonspecific manner but does not bind single-stranded DNA. hPso4 protein is induced 15- to 30-fold in cells by gamma radiation and chemical mutagens but not by UV treatment. Loss of hPso4 expression induced by siRNA results in accumulation of DSBs, apoptosis, and decreased cell survival after DNA damage. We conclude that hPso4 plays a major and previously undefined role in mammalian DNA DSB repair.

Proceedings of the 2nd Augmented Human International Conference (2011)

In order to tackle the problems of underdiagnosis and undertreatment of asthma in childhood general practitioners need to be aware of which children in their practices have or might have asthma. In an effort to identify a cohort of asthmatic or potentially asthmatic children a trained audit facilitator studied all the medical records of children aged between one year and 15 years who were registered with 12 Tayside general practices. From a total of 10,685 medical records the frequency of 'key items' sometimes associated with asthma were as follows: one or more episodes of bronchospasm or wheeze 23.7% of children, persistent cough 23.2%, treatment with anti-asthma therapy in the past 20.0%, exercise induced cough or wheeze 5.2% and history of 'wheezy bronchitis' 4.6%. However, in only 896 children (8.4%) had a formal diagnosis of asthma been made. Of all the children, 5.4% had received a prescription for anti-asthma medication within the past three months. Only 1.2% were taking an inhaled corticosteroid and 1.0% sodium cromoglycate, but many more were taking inhaled bronchodilators (3.1%) and oral bronchodilators (1.7%). The findings suggest that a systematic review of medical records by a trained facilitator can identify those children who could benefit from clinical review. Practices who wish to know which of their children have or might have asthma should consider using medical record review to search for key items associated with asthma.
A Study on Fabrication and Performance Evaluation of a Driving Amplifier Stage for UHF Transmitter in Digital TV Repeater (2003)

본 논문에서는 UHF(470∼806 MHz) 대역에서 전송장치로 사용 가능한 DTV 중계기용 1 Watt 급 구동증폭단을 설계 및 제작하였다. 구동증폭단은 유전율 2.53, 두께 0.8 mm 기판을 사용하여, 전치증폭기 및 1 Watt 단위증폭기를 단일기판상에 집적화 하였다. 바이어스 전압 28 V DC, 전류 900 mA를 구동증폭단에 인가하였을 때, 470∼806 MHz의 대역에서 53.5 dB 이상의 이득, <TEX>$\pm$</TEX>0.5 dB의 이득 평탄도 및 -12 dB 이하의 입ㆍ출력 반사손실이 나타났다. 또한 출력전력이 1 Watt일 때 사용주파수 대역에서 2 MHz 주파수 간격의 두 신호를 구동증폭단에 입력하여 설계사양보다 우수한 48 dBc 이상의 상호변조왜곡 특성이 나타남을 알 수 있었다. In this paper, a driving amplifier stage with 1 Watt output has been designed and fabricated, which is operating at UHF band( 470 ∼ 806 MHz) for digital TV repeater. In the driving amplifier stage, preamplifier and 1 Watt unit amplifier are integrated by one electric substrate which is 2.53 in dielectric constant and 0.8 mm thickness. When the driving amplifier stage is flown by bias voltage of 28 V DC and current of 900 mA. it has the gain of more than 53.5 dB. the gain flatness of <TEX>$\pm$</TEX>0.5 dB and return loss of less than -15 dB in 470 ∼ 806 MHz. Also, when two signals at 2 MHz frequency interval are input port into the driving amplifier stage with 1 Watt output, it resulted in excellent characteristics to designed specification with showing intermodulation distortion characteristics of more than 48 dBc.
High-Pressure Calibration: A Critical Review (1972)

A critical review of experimental technique for measuring high pressures has been made. The broad coverage includes discussions relating to (a) the establishment of a primary pressure scale using the free-piston gage, (b) the selection and precise measurement of identifiable phase changes as fixed pressure points, and (c) the use of interpolation and extrapolation techniques such as resistance gages, equations of state, and optical changes. The emphasis is on static pressure measurements above 10 kbar, but shock measurements are also considered for completeness. The pressure values to be associated with the fixed points have been analyzed in detail. Temperature measurement in the high pressure environment is also reviewed. The accuracy with which pressures can be measured has been carefully considered; the maximum accuracies now obtainable are considered to be of the order of 0.02 percent at 8 kbar, 0.25 percent at 25 kbar, 2 percent at 50 kbar, and 4 percent at 100 kbar.
Insulin-Like Growth Factor I Gene Transfer to Cirrhotic Liver Induces Fibrolysis and Reduces Fibrogenesis Leading to Cirrhosis Reversion in Rats (2009)

IGF-I gene transfer to cirrhotic livers induces MMPs and hepatoprotective factors leading to reversion of fibrosis and improvement of liver function. IGF-I gene therapy may be a useful alternative therapy for patients with advanced cirrhosis without timely access to liver transplantation.
[HMG-CoA reductase inhibitor for therapy of patients with hyperlipoproteinemia ]. (1994)

The discovery and production of HMGCoA reductase inhibitor and the fundamental research work of the LDL receptor unraveled a receptor-mediated cholesterol homeostasis. HMGCoA reductase inhibitors are the most commonly prescribed class of lipid-lowering drugs in many countries. The decrease of the intracellular cholesterol caused by the inhibitor induces the compensatory increase of LDL receptor protein at liver plasma membrane. The increased receptor promotes LDL catabolism and results in decrease of plasma LDL. Serious side effects involving the liver or muscle are rare. But the risk of myopathy is increased when the drug is used with other hypolipidemic agents. A principle of the treatment of hyperlipidemia, including secondary one associated with diabetes mellitus and renal disease, by HMGCoA reductase is discussed in this review.

Optimal multi-drug PK sampling strategies (OSS) for efavirenz (EFV) & indinavir (IDV) (2005)

Aims Intensive sampling strategies (ISS) are not feasible in many patient populations. Methods to design sparse OSS have not been adequately described for multi-drug regimens. The objective of the present study was to develop a sparse efficient multi-drug OSS for evaluation of PK in patients receiving antiretroviral (ARV) regimens. Methods Two OSS with 4 or 6 sampling times (OSS4, OSS6) constrained to 8h post-dose at steady state were computed using D-optimality (ADAPT II). These OSS were developed based on 'intensive' steady state PK data modeled using ADAPT II from 14 healthy volunteers in ACTG A5043 given EFV, IDV and amprenavir. Bias and precision of OSS estimates of clearance (CL), compared to estimates based on the ISS, were determined. Results OSS4 had samples at pre, 2, 5 and 8h post-dose; OSS6 added 1 and 4h samples. For both of the OSS, CL estimates were unbiased. Mean absolute errors for EFV were 5.6 and 3.9% and for IDV were 15.8 and 4.1%, for OSS4 and OSS6, respectively. Conclusion This approach to designing sparse OSS will facilitate PK/PD studies in patient populations receiving multi-drug ARV regimens.

Antenna Measurement on Cylindrical Surface in Fresnel Region Using Direct Far-Field Measurement System (2007)

The small anechoic chambers built by many small-/medium-sized companies and universities present difficulties in testing electrically large antennas because the chamber size cannot satisfy the far-field criterion of large antennas. In this paper, a method for Fresnel-region measurement on a cylindrical surface with variation of the measurement height is proposed and verified by both calculations and experiments. We implement the proposed method using a direct far-field measurement system by adding a few supporting structures. The results show good accuracy.
The Arabidopsis ATP-BINDING CASSETTE Transporter ABCB21 Regulates Auxin Levels in Cotyledons, the Root Pericycle, and Leaves (2019)

The phytohormone auxin plays significant roles in regulating plant growth and development. In Arabidopsis, a subset of ATP-BINDING CASSETTE subfamily B (ABCB) transporters participate in polar movement of auxin by exclusion from and prevention of reuptake at the plasma membrane. A previous analysis identified ABCB21 as a conditional auxin uptake/efflux transporter that regulates cellular auxin levels, but clear physiological roles for ABCB21 <i>in planta</i> remain unknown. Here we show that ABCB21 maintains the acropetal auxin transport stream by regulating auxin levels in the pericycle. Loss of ABCB21 reduces rootward auxin transport and delays lateral root emergence. In seedling shoots, ABCB21 regulates mobilization of auxin from the photosynthetic cotyledons that is important for phototropic bending. In rosette leaves ABCB21 contributes to lateral auxin distribution. These results support a primary role for ABCB21 in regulating auxin distribution supplementary to the primary ABCB auxin transporters ABCB1 and 19.
Importance of deposit information in the design and execution of steam generator chemical cleaning (1997)

During the planning stages of the chemical cleaning of the San Onofre Nuclear Generating Station (SONGS) units 2 and 3 steam generators, it was determined that an understanding of the steam generator deposit loading and composition was essential to the design and success of the project. It was also determined that qualification testing, preferably with actual deposits from the SONGS steam generators, was also essential. SONGS units 2 and 3 have Combustion Engineering (CE)-designed pressurized water reactors. Each unit has two CE model 3410 steam generators. Each steam generator has 9350 alloy 600 tubes with 1.9-cm (3/4 in.) outside diameter. Unit 2 began commercial operation in 1983, and unit 3, in 1984. The purpose of this technical paper is to explain the effort and methodology for deposit composition, characterization, and quantification. In addition, the deposit qualification testing and design of the cleaning are discussed.
First down converter multilayers integration in an industrial Si solar cell process (2018)

Abstract Down converter SiN x :Yb 3+ /SiN x :Tb 3+ multilayers are deposited by reactive magnetron cosputtering with the objective of optimizing the interaction distance between Tb 3+ and Yb 3+ ions to favor a better light management in Si solar cells. Those Si‐based multilayers are developed to be compatible with the Si photovoltaic technology. The deposition parameters are optimized to enhance the emission of the Yb 3+ ions in the IR region. The emission efficiency of such multilayer structure is compared with a mixed RE SiN x :Tb 3+ ‐Yb 3+ layer evidencing a gain resulting from a better management of the Tb 3+ and Yb 3+ ions distance. At the end, we integrate the growth of such a multilayer in an industrial Si solar cell process and demonstrate the existence of a frequency conversion effect that is promising for the future increase of the Si solar cell efficiency.
The Feasibility of 18-mm-Diameter Colonic Stents for Obstructive Colorectal Cancers (2017)

The 18-mm-diameter stents were similarly effective when compared with 22-mm-diameter stents. Because 18-mm-diameter stents are easy to handle and produce less mechanical stress, they have the potential to decrease the perforation rate and mitigate the stent's impact on the tumors. 18-mm-diameter stents can be useful and safe, especially as a BTS.

A new class of chitosan derivatives possessing coumarins was synthesized to improve the antioxidant activity of chitosan.
Route-planning based on a passenger condition for self-driving vehicles (2017)

This paper proposes a route-planning method for an environment in which self-driving vehicles are widely used. Such vehicles will plan their route based on the passenger's condition, which is recognized using a biological sensor. Various carmakers and IT companies have recently developed various technologies for self-driving vehicles, Google, Inc. being one. In this paper, we focus on a technique for route planning. In particular, we discuss how to realize the avoidance of traffic congestion. Our self-driving vehicles generate a new route to avoid traffic congestion when it occurs. We adopted a time-constrained heuristic search (TCS) to which we can set the time limit in advance. If we set a longer time limit, routes closer to the optimal route can be generated. A TCS ensures that vehicles can obtain an avoidance route without stopping before entering the traffic congestion. We executed some experiments concerning the relationship between total efficiency and the diffusion rate of self-driving vehicles using our own self-developed traffic simulator. As a result, we were able to clarify the phenomenon in which a peak in the total efficiency occurs, and decreases as more vehicles generate avoidance routes. Therefore, it is not always best to generate an avoidance route, and the decision to drive along the current route without generating an avoidance route becomes important in certain cases. Thus, we propose a method in which a vehicle judges whether to generate an avoidance route based on the passenger's condition. To detect the passenger's condition, we use a sitting-pressure sensor, which can detect the movements of the passenger's center of gravity. This sensor allows us to succeed in recognizing passenger fatigue. We can therefore make certain judgments: The vehicle will go along the current route if the passenger seems to be relaxed and in a comfortable atmosphere, the vehicle will arrive earlier by avoiding traffic congestion if the passenger seems to be tired or irritated, or the vehicle will stop for a break period if the passenger seems to be significantly tired.
Recovery of vanadium and nickel in fly ash from heavy oil (1995)

Abstract Recovery of vanadium and nickel from an oil fly ash is studied in a two‐step leaching process, carried out under ambient pressure without calcination. In the leaching, nickel is dissolved with NH 4 Cl in the first step, followed by vanadium leaching with Na 2 CO 3 in the second step. Both leachants depress the dissolution of iron and aluminium from the ash and hence the selective leachings are feasible. Nickel was recovered in 87% yield from the leach liquor by precipitation with Na 2 S, the purity of NiS being over 99% on the basis of the target metals (V, Ni, Fe, Al and Mg). For the recovery of vanadium, which has a relatively low concentration in the leach liquor, solvent extraction with TOA is preferable to concentration, prior to crystallization with NH 4 Cl. The experimental data showed that the vanadium concentration of the stripping solution is increased by about 15 times that of the leach liquor, which results in 78% yield as NH 4 VO 3 crystals.
Mechanisms of progression and regression of renal lesions of chronic nephropathies and diabetes (2006)

The incidence of chronic kidney diseases is increasing worldwide, and these conditions are emerging as a major public health problem. While genetic factors contribute to susceptibility and progression of renal disease, proteinuria has been claimed as an independent predictor of outcome. Reduction of urinary protein levels by various medications and a low-protein diet limits renal function decline in individuals with nondiabetic and diabetic nephropathies to the point that remission of the disease and regression of renal lesions have been observed in experimental animals and even in humans. In animal models, regression of glomerular structural changes is associated with remodeling of the glomerular architecture. Instrumental to this discovery were 3D reconstruction studies of the glomerular capillary tuft, which allowed the quantification of sclerosis volume reduction and capillary regeneration upon treatment. Regeneration of capillary segments might result from the contribution of resident cells, but progenitor cells of renal or extrarenal origin may also have a role. This review describes recent advances in our understanding of the mechanisms and mediators underlying renal tissue repair ultimately responsible for regression of renal injury.

Microbial community response to a bioaugmentation test to degrade trichloroethylene in a fractured rock aquifer, Trenton, N.J (2022)

Bioaugmentation is a promising strategy for enhancing trichloroethylene (TCE) degradation in fractured rock. However, slow or incomplete biodegradation can lead to stalling at degradation byproducts such as 1,2-dichloroethene (cis-DCE) and vinyl chloride (VC). Over the course of 7 years, we examined the response of groundwater microbial populations in a bioaugmentation test where an emulsified vegetable oil solution (EOS®) and a dechlorinating consortium (KB-1®), containing the established dechlorinator Dehalococcoides (DHC), were injected into a TCE-contaminated fractured rock aquifer. Indigenous microbial communities responded within 2 days to added substrate and outcompeted KB-1®, and over the years of monitoring, several other notable turnover events were observed. Concentrations of ethene, the end product in reductive dechlorination, had the strongest correlations (P< .05) with members of Candidatus Colwellbacteria but their involvement in reductive dechlorination is unknown and warrants further investigation.DHC never exceeded 0.6% relative abundance of groundwater microbial communities, despite its previously presumed importance at the site. Increased concentrations of carbon dioxide, acetic acid, and methane were positively correlated with increasing ethene concentrations; however, concentrations of cis-DCE and VC remained high by the end of the monitoring period suggesting preferential enrichment of indigenous partial dechlorinators over bioaugmented complete dechlorinators. This study highlights the importance of characterizing in situ microbial populations to understand how they can potentially enhance or inhibit augmented TCE degradation.
Caspase-6 Activation in Familial Alzheimer Disease Brains Carrying Amyloid Precursor Protein or Presenilin I or Presenilin II Mutations (2009)

We previously demonstrated the activation of caspase-6 (Casp-6) in the hippocampus and cortex in cases of mild, moderate, severe, and very severe Alzheimer disease (AD). To determine whether Casp-6 is also activated in familial AD, we performed an immunohistochemical analysis of active Casp-6 and Tau cleaved by Casp-6 in temporal cortex and hippocampal tissue sections from cases of familial AD. The cases included 5 carrying the amyloid precursor protein K670N and M671L Swedish mutation, 1 carrying the amyloid precursor protein E693G Arctic mutation, 2 each carrying the Presenilin I M146V, F105L, A431E, V261F, and Y115C mutations, and 1 with the Presenilin II N141I mutation. Active Casp-6 immunoreactivity was found in all cases. Caspase-6 immunoreactivity was observed in neuritic plaques or in some cases cotton-wool plaques, and in neuropil threads and neurofibrillary tangles. These results indicate that Casp-6 is activated in familial forms of AD, as previously observed in sporadic forms. Because sporadic and familial AD cases have similar pathological features, these results support a fundamental role of Casp-6 in the pathophysiology of both familial and sporadic AD.
