<title>Flutter and vibration control of an aluminum plate wing by piezoceramic actuators</title> (1998)

We carried out tests and analysis of flutter and vibration control of rectangular aluminum plate wing. The dimensions of the plate wing (420.0 X 140.0 X 1.0 mmt) were determined based on the wind tunnel size and blowing air velocity. The plate wing was driven by eight piezoceramic actuators bonded on the surfaces at the wing root part. Acceleration sensor was located at the wing tip and the signal was sent to digital signal processor through filters and control signal was sent to power amplifier. Amplified signal drove the piezoceramic actuator and suppressed vibration of the plate wing. System consist of structure, piezoceramic actuator and unsteady aerodynamic force was modeled into the standard form of modern control theory. Piezoceramic actuator's force was modeled using analogy of thermal analysis. Unsteady aerodynamic force in case of flutter control was calculated by DLM (frequency domain), then transformed to Roger's approximation for the purpose of time domain analysis. Full order control law consist of optimum regulator and Kalman's filter was reduced to low order law for practical use. First, we carried out the test for vibration control. In this case, structural damping ratio of the system increased remarkably in both case of gain control and reduced LQG control. Using gain control, that of the system increased up to 0.3. Second, we carried out the wind tunnel test of flutter control. Flutter speed at test increased about 2.9 m/s (10.8%, in calculation 12.2%) using reduced LQG controller.
Huge liver tumor in young man (2019)

Intrahepatic cholangiocarcinoma is the second leading primary hepatic tumors, accounting for 5% of all hepatic tumors. The curability depends on the operability; however, the difficulty of early diagnosis and late clinical presentation account for the poor prognosis. Therefore, development of a novel therapeutic option and a method to determine the viability of the primary tumor, which hinder the assessment of the impact of other therapies, including chemotherapy and radiotherapy are needed. Although FDG-PET has been used to detect distant metastases of ICC, which are present in 20% of patients at the initial diagnosis, little is known about the efficacy of FDG-PET of the primary lesion of ICC. Here, we present the case of a 31-year-old male diagnosed with unresectable ICC and successfully treated with carbon-ion radiation, and present the usefulness of fluorodeoxyglucose-positron emission tomography in the determination of the viability of the tumor.
Improving upon logistic regression to predict United States Army delayed entry program (DEP) losses (2004)

We improve upon McFadden's use of logistic regression for choice analysis. We investigate the use of neural networks, support vector machines, and random forest as functional approximations to improve upon the results obtained from logistic regression. The choice involves an Army enlisted applicant choosing between honoring their enlistment contract with the Army by shipping to basic combat training or choosing to not honor the contract and becoming a DEP Loss. An Army enlisted applicant is a person, who signs an active duty enlistment contract with the United States Army. The enlistment contract contains various terms, such as: the length of the service, the Army job (military occupational skill (MOS)), special schooling received by the applicant, and incentives. A shipper is an Army enlisted applicant, who initially honors their Army contract. A DEP Loss is an Army enlisted applicant, who doesn't honor their Army contract. We discover, for these data, both support vector machines and random forest outperform logistic regression. We also discover support vector machines outperforming all other functional approximations for these data. Performance is based on various metrics: error rate, type II error, and ROC curves.
Catalytic Synthesis of Salicylate Esters over Cordierite Honeycomb Coated with Mo (VI)/ZrO&lt;sub&gt;2&lt;/sub&gt; (2013)

Solid acids such as ZrO2 & Mo (VI)/ZrO2 were coated on a honeycomb monolith by impregnation method. These catalytic materials were characterized by NH3-TPD, PXRD and SEM techniques. Salicylate esters were synthesized via transesterification of methyl salicylate with different alcohols over these catalytic materials. An excellent yield of Salicylate esters was obtained under specific reaction conditions. A correlation between the surface acidity, PXRD phase and catalytic activity of Mo (VI)/ZrO2 was observed. The thermally regenerated catalytic material was reused repeatedly with a consistent high yield of salicylate esters. The honeycomb coated with zirconia catalysts were found to be economical, efficient and ecofriendly (3E concept).
Nonstationary spectral peak estimation by Monte Carlo filter (2002)

The aim of research is to estimate multiple peaks of the power spectrum that are varying with time. A model to estimate the time-varying peaks has been proposed by the author. The model is written in a state space representation composed of a system model and an observation model. The system model denotes smooth change of a state vector that consists of pairs of peak frequency and bandwidth. The observation model is an autoregressive model with time-varying coefficients that are nonlinearly parametrized by the state vector. The nonlinear parametrization is based on the fact that the pairs of frequency and bandwidth are roots of the characteristic equation of the autoregressive model. By estimating the state vector giving the observations results, the estimation of the frequency and bandwidth pairs results in a time-varying power spectrum. In state estimation, the nonlinear and non-Gaussian properties should be treated because of the nonlinear formulation of the model. As a method of state estimation, we have employed an approximation of non-Gaussian distribution and its realizations, called the Monte Carlo filter. Through numerical examples, the estimation precision of the peak frequency has been checked by comparison with a conventional model.
Efficient In‐Situ Redox Catalytic NAD(P)+ Regeneration in Enzymatic Synthesis Using Transition‐Metal Complexes of 1,10‐Phenanthroline‐5,6‐dione and Its N‐Monomethylated Derivative as Catalysts (1997)

Abstract In comparative studies, we have been able to demonstrate that redox catalysts based on transition‐metal complexes using 1,10‐phenanthroline‐5,6‐dione as a ligand or based on N ‐methylated 1,10‐phenathroline‐5,6‐dione acting via hydride ion abstraction are superior to alternative methods for the redox catalytic aerobic or indirect electrochemical in situ NAD(P) + regeneration in enzymatic syntheses using alcohol dehydrogenases as production enzymes. Under preparative conditions in the gram scale we were able to obtain turnover frequencies of up to 130 turnovers per hour with respect to the redox catalyst. These are far larger than those of the presently most popular regeneration system.
A Low-Jitter Low-Phase-Noise 10-GHz Sub-Harmonically Injection-Locked PLL With Self-Aligned DLL in 65-nm CMOS Technology (2014)

In this paper, we present design and analysis of an innovative low-jitter low-phase-noise 10-GHz sub-harmonically injection-locked phase-locked loop (PLL) with self-aligned delay-locked loop in 65-nm CMOS technology. With the proposed innovative topology, the phase between the injection signal and the voltage-controlled oscillator in the PLL can be dynamically aligned to minimize the jitter over the variations. A modified theoretical model of the sub-harmonically injection-locked PLL with self-aligned injection is developed for the design methodology. The in-band phase noise of the sub-harmonically injection-locked PLL can be significantly improved using the self-aligned sub-harmonically injection-locked technique. The design considerations of the locking range, loop bandwidth, and frequency division ratio are addressed. At 10 GHz, the measured phase noise of the proposed PLL with self-aligned injection at 1-MHz offset is -130.2 dBc/Hz with a root-mean-square jitter of 44 fs. The total dc power consumption is 62.7 mW. From 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C to 70 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C, the measured phase noise at 1-MHz offset and jitter are better than -129 dBc/Hz and 48 fs, respectively. This work demonstrates excellent performance and good robustness over the variations, and it can be compared to the previously reported state-of-the-art sub-harmonically injection-locked PLLs.
A novel mechanism by which N-(4-hydroxyphenyl)retinamide inhibits breast cancer cell growth: the production of nitric oxide. (2002)

N-(4-Hydroxyphenyl)retinamide (4-HPR) induces apoptosis in breast cancer cells; however, the molecular basis by which 4-HPR induces apoptosis is not well understood. In breast cancer cells, nitric oxide (NO) is predominantly an apoptotic inducer. Apoptotic agents, such as phorbol ester, tumor necrosis factor-alpha, and peptide hormones, have been shown to increase NO production in breast cancer cells. Therefore, we hypothesized that the production of No is vital for 4-HPR to induce apoptosis in breast cancer cells. We found that 4-HPR induced NO production in a dose-dependent manner in all of the breast cancer cell lines tested. The degree of growth inhibition and apoptotic induction by 4-HPR was directly correlated with the amount of NO produced. To prove that NO is essential for 4-HPR to induce apoptosis, breast cancer cells were coincubated with a competitive NO synthase (NOS) inhibitor, NG-monomethyl-L-arginine (L-NMMA), and 4-HPR, L-NMMA prevented 4-HPR from inducing inhibitory effects, indicating that NO is crucial for 4-HPR to induce its apoptotic effects in breast cancer cells. IFNs and tamoxifen (TAM) have been shown to potentiate 4-HPR effects in breast cancer cells. Both IFN-gamma and TAM enhanced the ability of 4-HPR to induce NO production in breast cancer cells, which was correlated with increased apoptosis. Alone, 4-HPR increased expression of both inducible NOS (NOSII) and endothelial NOS (NOSIII). When combined with 4-HPR, IFN-gamma and TAM enhanced NOSII expression. Thus, we have identified a novel mechanism by which 4-HPR induces apoptosis in breast cancer cells, i.e., by increasing NOS expression to induce NO production.

Parathyroid Hormone-Related Protein-Induced Hypercalcemia in SCID Mice Engrafted With Adult T-Cell Leukemia Cells (1998)

Parathyroid hormone-related protein (PTHrP) is considered to be one of the main causes of hypercalcemia associated with adult T-cell leukemia (ATL). To clarify the role of PTHrP and bone remodeling in the development of hypercalcemia in ATL, we examined the SCID mouse model of ATL that has previously been shown to mimic the disease in humans. Using this model, we found clear elevations in serum levels of calcium and C-terminal PTHrP (C-PTHrP). PTHrP mRNA was highly expressed in ATL cells proliferating in vivo. After the development of hypercalcemia, ATL mice were killed and bone histomorphometric analysis was performed. Bone volume was clearly decreased in the ATL mice. In comparison to control SCID mice, bone formation indices were very low in the ATL mice. Surprisingly, no significant difference was detected between the ATL mice and the control SCID mice in eroded surface/bone surface (ES/BS), a parameter of bone resorption. To our knowledge, the model presented here is the first animal model of ATL with humoral hypercalcemia. This is in contrast to previously reported, well-characterized animal models of human solid tumors associated with humoral hypercalcemia of malignancy (HHM). Furthermore, this model not only provides us with the opportunity to study the mechanisms underlying development of elevated calcium levels in ATL, but also allows us to test new therapeutic agents designed to treat hypercalcemia.
Responses of stored‐product Anobiidae to pheromone lures and plant‐derived volatiles (2008)

Abstract Experiments were conducted in different locations to investigate responses of adult Stegobium paniceum and Lasioderma serricorne (Col., Anobiidae) to different commercially available or prototype fabrications of their female‐produced sex pheromones. The results showed that the number of S. paniceum captured in traps baited with the commercially available lures was significantly higher than those captured in traps baited with the prototype stegobinone lures. The three commercially available brands of serricornin lures investigated were equally effective in capturing L. serricorne. In a related study, we conducted a 9‐week trapping experiment to determine if responses of L. serricorne to serricornin can be enhanced by the presence of host plant odours. Traps were baited with serricornin alone, serricornin plus dried red chilli ( Capsicum frutescens L.) or red chilli alone. The results showed that the number of beetles captured in traps baited with a combination of serricornin and chilli volatiles were significantly higher than in traps baited with pheromone or chilli volatiles alone, indicating that potential exist for improved monitoring or mass trapping of L. serricorne by combining pheromone with plant‐derived volatiles present in Capsicum spp.
Comparison of 1-D, 2-D and 3-D Printer Calibration Algorithms with Printer Drift (2005)

For consistent color reproduction, a digital printer must operate in a stable mode. However, due to uncertainties such as changes in humidity and temperature, color printers drift over time. Calibration is an approach that can be used to bring back the printer to its initial state from a drifted state. Different algorithms are used to calibrate printers. Among them are one-dimensional gray balance, one-dimensional channelwise linearization, two-dimensional calibration, and three-dimensional calibration. In this paper, we benchmark the performance of different calibration algorithms in stabilization of digital color printers subject to printer drift. The figure of merit used for comparison is the improvement in CIELAB &#x394;E between the output of calibrated machine and the output of the machine in a drifted mode for the same input. We also examine the optimum number of color patches needed to be measured for calibrating the machine with different calibration algorithms. The optimum number of patches is selected using dynamic optimization algorithm. Simulation results are presented using real printer data.
Highly sensitive xylene sensors using Fe2O3-ZnFe2O4 composite spheres (2021)

Pure ZnFe2O4 and Fe2O3-ZnFe2O4 hetero-composite spheres were prepared by ultrasonic spray pyrolysis of a solution containing Znand Fe-nitrates. Additionally, the sensing characteristics of these spheres in the presence of 5 ppm ethanol, benzene, p-xylene, toluene, and CO (within the temperature range of 275-350 ℃) were investigated. The Fe2O3-ZnFe2O4 hetero-composite sensor with a cation ratio of [Zn]:[Fe]=1:3 exhibited a high response (resistance ratio = 140.2) and selectivity (response to p-xylene/response to ethanol = 3.4) to 5 ppm p-xylene at 300 ℃, whereas the pure ZnFe2O4 sensor showed a comparatively lower gas response and selectivity. The reasons for the superior response and selectivity to p-xylene in Fe2O3-ZnFe2O4 hetero-composite sensor were discussed in relation to the electronic sensitization due to charge transfer at Fe2O3-ZnFe2O4 interface and Fe2O3-induced catalytic promotion of gas sensing reaction. The sensor can be used to monitor harmful volatile organic compounds and indoor air pollutants.
Parental Educational Investment and Children's Academic Risk: Estimates of the Impact of Sibship Size and Birth Order from Exogenous Variations in Fertility (2005)

The stylized fact that individuals who come from families with more children are disadvantaged in the schooling process has been one of the most robust effects in human capital and stratification research over the last few decades. For example, Featherman and Hauser (1978: 242-243) estimate that each additional brother or sister costs respondents on the order of a fifth of a year of schooling.
Single nucleotide polymorphism in fibroblast growth factor receptor 4 at codon 388 is associated with prognosis in high‐grade soft tissue sarcoma (2003)

In the current study, the authors found a significant correlation between FGFR4 SNP and prognosis in patients with soft tissue sarcoma, although the samples were comprised of various histologic types. This SNP might be used to improve the prediction of clinical prognosis and lead to new treatment strategies in patients with soft tissue sarcomas.
Feature-based image alignment via coupled Hough transforms (2009)

We investigate the problem of feature based image alignment under vertical and horizontal translation and scaling. The problem of finding the two dimensional affine alignment without rotation can be separated into two coupled simpler problems. The resulting two model fitting problems are coupled through a consensuses set of points that fit both models. The proposed solution can be viewed as a coordinate-wise optimization that separates the two dimensional shift and stretch problem into two coupled one-dimensional problems. Each one dimensional alignment problem is solved through a Hough transform that allows fast and robust estimation of the two parameters of a one dimensional affine deformation model. Experimental results demonstrate the efficiency and accuracy of the proposed method in finding the spatial transform between two given video sequences.
Interface trap passivation for SiO2∕(0001¯) C-terminated 4H-SiC (2005)

Interface trap passivation at the SiO2∕carbon-terminated (0001¯) face of 4H-SiC utilizing nitridation and hydrogenation has been evaluated. The SiO2∕SiC interface, created by dry thermal oxidation on the C face, shows appreciably higher interface state density near the conduction band compared to the (0001) Si face. A postoxidation anneal in nitric oxide followed by a postmetallization anneal in hydrogen results in dramatic reduction of the trap density by over an order of magnitude near the conduction band. The electrical measurements have been correlated with the interfacial chemistry.
Sensitization of Transforming Growth Factor-β Signaling by Multiple Peptides Patterned on DNA Nanostructures (2020)

We report sensitization of a cellular signaling pathway by addition of functionalized DNA nanostructures. Signaling by transforming growth factor β (TGFβ) has been shown to be dependent on receptor clustering. By patterning a DNA nanostructure with closely spaced peptides that bind to TGFβ we observe increased sensitivity of NMuMG cells to TGFβ ligand. This is evidenced by translocation of secondary messenger proteins to the nucleus and stimulation of an inducible luciferase reporter at lower concentrations of TGFβ ligand. We believe this represents an important initial step towards realization of DNA as a self assembling and biologically compatible material for use in tissue engineering and drug delivery.
[A study of soluble form of L-selectin in blood of patients with neuroimmunological disorders]. (1996)

Members of the selection family mediate the first step of leukocyte-endothelial cell interaction in inflammatory lesion. We have examined the soluble form of L-selectin (sL-selectin) in patients with neuroimmunological disorders (48 multiple sclerosis, 2 Balo's sclerosis, 18 Guillain-Barré syndrome, 7 Miller-Fisher syndrome, 8 chronic inflammatory demyelinating polyneuropathy, and 25 human T-lymphotropic virus type-1 associated myelopathy). The levels of sL-selectin were measured by monoclonal antibody-based enzyme immunoassay on serum samples taken from patients with neuro immunological disorders. The level of sL-selectin were significantly decreased in the blood of patient with inactive stage of multiple sclerosis (MS), Guillain-Barré syndrome (GBS), and human T-lymphotropic virus type-1 associated myelopathy (HAM). The levels of sL-selectin in the sera of patients with active phase of MS tended to be high, but not significantly increased. The levels of sL-selectin, however, in the sort of patients with Balo's concentric sclerosis tended to be decreased. Thus, the findings that the serum concentrations of sL-selectin were decreased in stable phase of MS and acute phase of GBS and HAM suggest that sL-selectin may be differently involved in between patients with MS and patients with GBS or HAM.

Development of Inverse Raman Spectroscopy for Probing Rapidly Decomposing Explosives and Propellants (1981)

The techniques of inverse Raman spectroscopy and coherent anti-stokes Raman spectroscopy are considered for the purpose of development of rapid (single-shot) broad band detection of species in rapidly (explosively) decomposing materials. Experiments using inverse Raman spectroscopy with pulsed ruby laser, broad-band dye, 1-M spectrometer and optical multichannel analyzer are described. Results on benzaldehyde (neat and in mixtures with toluene) yield information on the quantitative limits of inverse Raman detection.
A HW/SW Implementation on FPGA of Absolute Robot Localization Using Webcam Data (2017)

This paper presents an implementation of absolute robot localization algorithm using FPGA technology. The adopted localization method uses webcam tracking images. This technique has been developed and implemented for the motion of the robot from an initial position towards another desired position. Firstly, we have validated the proposed approach on PC platform using C language and Open CV library. Secondly, to facilitate robot autonomous navigation, a mixed HW/SW implementation was been developed using a high performance version of the NIOS processor coupled with a custom hardware accelerator. Experimental tests on Altera Cyclone III FPGA Starter Kit show an improvement of 85% over purely software execution which proves the effectiveness of this proposed architecture.
FIGO good practice recommendations on magnesium sulfate administration for preterm fetal neuroprotection (2021)

Abstract In women at risk of early preterm imminent birth, from viability to 30 weeks of gestation, use of MgSO4 for neuroprotection of the fetus is recommended. In pregnancies below 32–34 weeks of gestation, the use of MgSO4 for neuroprotection of the fetus should be considered. MgSO4 should be administered regardless of the cause for preterm birth and the number of babies in utero. MgSO4 should be administered when early preterm birth is planned or expected within 24 h. When birth is planned, MgSO4 should commence as close as possible to 4 h before birth. If delivery is planned or expected to occur sooner than 4 h, MgSO4 should be administered, as there is still likely to be an advantage from administration within this time. The optimal regimen of MgSO4 for fetal neuroprotection is an intravenous loading dose of 4 g (administered slowly over 20–30 min), followed by a 1 g per hour maintenance dose. This regimen should continue until birth but should be stopped after 24 h if undelivered. When MgSO4 is administered, women should be monitored for clinical signs of magnesium toxicity at least every 4 h by recording pulse, blood pressure, respiratory rate, and deep tendon (for example, patellar) reflexes.
