A Pretreatment Method for the Velocity of DVL Based on the Motion Constraint for the Integrated SINS/DVL (2016)

It is difficult for autonomous underwater vehicles (AUVs) to obtain accurate aided position information in many locations because of underwater conditions. The velocity accuracy from the Doppler velocity log (DVL) is a key element in deciding the AUV position accuracy when the integration system of Strapdown Inertial Navigation System/DVL/Magnetic Compass/Press Sensor (SINS/DVL/MCP/PS) is adopted. However, random noise and sudden noise in DVL caused by sound scattering, fishing populations, and seafloor gullies introduce level attitude errors and accumulate as position error. To restrain random noise, a velocity tracing method is designed based on the constant velocity model and the assumption of slow motion of AUV. To address sudden noise, a fault diagnosis method based on the χ 2 rule is introduced to judge sudden changes from innovation. When a sudden change occurs, the time update of the velocity from the tracing model is used for data fusion instead of the velocity from DVL. Simulation test results indicate that with this velocity tracing algorithm, random noise in the DVL can be effectively restrained. The level attitude accuracy and the level position accuracy are also improved with the time update of the velocity when the sudden change occurs.
Two‐step radiosynthesis of [18F]N‐succinimidyl‐4‐fluorobenzoate ([18F]SFB) (2009)

Abstract The acylation reagent [ 18 F] N ‐succinimidyl‐4‐fluorobenzoate ( 18 F‐SFB) has been prepared using a new two‐step approach. The starting material p‐ [ 18 F]fluorobenzaldehyde ( 18 F‐FBA) was obtained by an improved radiosynthesis with a decay‐corrected radiochemical yield of 66±6 % ( n =3). Reaction of 18 F‐FBA with (diacetoxyiodine)benzene and N ‐hydroxysuccinimide and preparative HPLC purification furnished 18 F‐SFB in an r.c.y. of 49±6 % ( n =3), based on the starting radioactivity of 18 F‐FBA. The radiochemical purity of 18 F‐SFB was &gt;99%. Alternatively, purification by solid phase extraction gave 18 F‐SFB with an r.c.y. of 77±9% ( n =4) and a radiochemical purity of 89±5% ( n =4). This radiochemical synthesis only used non‐aqueous solvents, which simplifies the method and facilitates subsequent applications of 18 F‐SFB. Copyright © 2009 John Wiley &amp; Sons, Ltd.

Evidence That Inhibition of Hemojuvelin Shedding in Response to Iron Is Mediated through Neogenin (2007)

Hemojuvelin (HJV), encoded by the gene HFE2, is a critical upstream regulator of hepcidin expression. Hepcidin, the central iron regulatory hormone, is secreted from hepatocytes, whereas HFE2 is highly expressed in skeletal muscle and liver. Previous studies demonstrated that HJV is a GPI-anchored protein, binds the proteins neogenin and bone morphogenetic proteins (BMP2 and BMP4), and can be released from the cell membrane (shedding). In this study, we investigated the physiological significance and the underlying mechanism of HJV shedding. In acutely iron-deficient rats with markedly suppressed hepatic hepcidin expression, we detected an early phase increase of serum HJV with no significant change of either HFE2 mRNA or protein levels in gastrocnemius muscle. Studies in both C2C12 (a mouse myoblast cell line) and HepG2 (a human hepatoma cell line) cells showed active HJV shedding, implying that both skeletal muscle and liver could be the source of serum HJV. In agreement with the observations in iron-deficient rats, HJV shedding in these cell lines was down-regulated by holo-transferrin in a concentration-dependent manner. Our present study showing that knock-down of endogenous neogenin, a HJV receptor, in C2C12 cells suppresses HJV shedding and that overexpression of neogenin in HEK293 cells markedly enhances this process, suggests that membrane HJV shedding is mediated by neogenin. The finding that neither BMP4 nor its antagonist, noggin, was able to alter HJV shedding support the lack of involvement of BMP signaling pathway in this process.

Left ventricular muscle mass and diastolic function in patients with essential hypertension under long‐term clonidine monotherapy (1991)

To determine whether alterations of left ventricular (LV) structure are associated with improved LV function under chronic clonidine monotherapy (300-450 g/day) of essential hypertension, 11 male patients (age range 47-61 years) were followed for 5.4 +/- 0.9 months using echocardiography and Doppler echocardiography. Blood pressure decreased from a mean of 168/105 to 150/96 mmHg (p less than 0.01), heart rate remained unchanged (73 +/- 10 vs. 71 +/- 10 beats/min). LV muscle mass decreased from 350 +/- 73 to 297 +/- 56 g (p less than 0.02), LV volume/muscle mass ratio increased from 0.58 +/- 0.13 to 0.69 +/- 0.12 ml/g (p less than 0.005). Ejection time increased from 276 +/- 17 to 296 +/- 17 ms (p less than 0.01), whereas no significant change was found for pre-ejection period, ejection fraction, cardiac index and LV dimensions. Doppler analysis revealed improved isovolumic relaxation time (116 +/- 17 vs. 84 +/- 28 ms; p less than 0.05), but no change in isovolumic contraction duration, maximal inflow velocities, time-velocity integrals and their duration, rate of acceleration and deceleration of early and atrial filling, and of their ratios. It is concluded that no reliable improvement in diastolic or systolic LV function is observed in chronic clonidine monotherapy of essential hypertension despite a normalization of blood pressure and a regression of LV hypertrophy.
Chemical constituents and antimicrobial activities of the essential oil ofAcroptilon repens (L.) DC (2005)

The volatile oil from the aerial parts of Acroptilon repens (L.) DC. (Russian knapweed) growing wild in Iran was investigated by GC and GC–MS. Twenty-two components, representing 84.0% of the oil, were identified. The main constituents of the oil were caryophyllene oxide (36.6%), α-copaene (15.6%), β-caryophylene (10.0%) and β-copaene-4-α-ol (5.0%). In addition, the oil was assayed against six Gram-positive and Gram-negative bacteria by measuring the growth inhibitory zone. The oil of A. repens inhibited the growth of Gram-positive bacteria. Staphylococcus saprophyticus and Staphylococcus epidermidis showed strong inhibition zones, while Staphylococcus aureus showed a lower inhibition. The Gram-negative bacteria were insensitive to the oil. Copyright © 2005 John Wiley & Sons, Ltd.

Activation-induced cytidine deaminase mRNA levels in chronic lymphocytic leukemia (2010)

The Rai and Binet staging systems, which are used as standard methods for evaluating the prognosis of chronic lymphocytic leukemia (CLL), have some restrictions in identifying patients with early-stage CLL who will progress rapidly. To solve this defect, other prognostic parameters have become important in recent years. Intracellular up-regulation of the AID gene in the leukemic lymphocytes of patients with CLL may be an important parameter for predicting the progression of CLL. In this study, AID mRNA expression levels were evaluated in 50 patients with CLL and 50 healthy controls. AID mRNA expression was significantly higher in patients than in controls. We then evaluated AID mRNA levels according to the stages of CLL. Regarding AID mRNA levels, patients with Rai stages 0, I, and II were compared with patients with stages III and IV, whereas patients with Binet stage A were compared with patients with Binet stages B and C. In patients with higher-risk Rai stages III and IV and Binet stages B and C, activation-induced cytidine deaminase (AID) mRNA levels were also significantly higher. Additionally, we found that the mRNA levels of patients with AID in CLL were eight-fold higher than those in control patients, suggesting that AID overexpression promotes chromosomal abnormalities and is associated with CLL progression and survival. For this reason, and because of the simplicity of quantitative real-time PCR analysis, AID might be a useful clinical parameter after its importance is confirmed in larger and multivariate studies.
Electrically Switchable Monostable Actuatoric Polymer-Based Nanovalve Arrays with a Long-Term Stability (2018)

Here we present a novel electrically switchable nanovalve array based on an intrinsic conductive polymer that has the capabilities to change its volume depending on its redox state. The polymer is created by anodic deposition of a sodium dodecylbenzenesulfonate (DBS)-doped polypyrrole (PPy). Optimization of the DBS-doped PPy layers revealed an actuatoric performance of up to 10% out of plane volume change. More interestingly, the electrochemical characterization revealed an actuatoric monostable polymer that could be used to fabricate nanovalve arrays that have a native opened state when no potential is applied and that can be closed when a reductive potential is applied. As a proof of concept, Atto488-labeled biotin (Biotin-Atto488) was used as a model compound and defined nanovalve arrays with nanopores in the range of 10 nm in diameter (opened state) were fabricated. Afterward, we were able to successfully prove the functionality of our nanovalve array by monitoring the flow-through rates of the Biotin-Atto488. More strikingly, we could demonstrate for the first time the robust and long-term stability of our nanovalve array without any performance loss for at least 72 h and retention capabilities of up to 90%. Furthermore, the demonstrated long-term stability was achieved under biocompatible conditions without the need of toxic dopant supplementation of the flow-through solution. Thus, our novel functional long-term stable nanovalve array offers the capabilities for practical applications.
Energy, economic analysis and efficiencies of micro drip irrigation II- Economic Analysis and efficiencies (2014)

Research study was carried out for two successive seasons 2012 and 2013 on seven years old (Florda prince) peach trees (Purnus perseca L. Batsch) budded on Nemagard rootstock. The experiment was conducted at the experimental farm, modern reclamation lands, situated Bader City, South Al-Tahrir, Al-Beharia Governate, Egypt. Peach trees were planted at 5 x 4 m in sandy soil, and were irrigated using four techniques of drip irrigation systems: Gr surfacr drip (SD) 4 l/h., Gr subsurface drip (SSD), surface micro drip (SMD) 0.5 l/h, and subsurface micro drip(SSMD) under three amount of applied water (60, 80, 100% of applied water will be called T 1 , T 2 and T 3 ). Fourty two experimental trees were selected of normal growth with uniform of vigor. Statistical design was split with three replicets. And results show that, The best irrigation water save is 20% for T 2 under all of SMD and SSMD irrigation system, on the other hand, T 1 under SMD irrigation system in all of first and second year is acceptance by irrigation water saving ratio 40%, the high gradation for CWUE under various water amounts, T 1 water treatment is the higher value then T 2 and T 3 under various drip irrigation systems The mean value of EEIS higher percentage in SSMD and SMD irrigation systems than its counterpart in SSD and SD irrigation system, beside at under all of SSMD irrigation systems is increasing with water amount increasing, The average energy production under SMD and SSMD irrigation systems is higher than SD and SSD irrigation systems by 18.8%,cost of unit production unit (LE/kg) for SSMD and SMD irrigation systems are lower than SSD and SD irrigation systems by (32-38,3%) at first season and (28,7-32%) at second season approximately.
Venoarterial Extracorporeal Membrane Oxygenation With Concomitant Impella Versus Venoarterial Extracorporeal Membrane Oxygenation for Cardiogenic Shock (2019)

There are contrasting data on concomitant Impella device in cardiogenic shock patients treated with venoarterial extracorporeal membrane oxygenation (VA ECMO) (ECPELLA). This study sought to compare early mortality in patients with cardiogenic shock treated with ECPELLA in comparison to VA ECMO alone. We reviewed the published literature from 2000 to 2018 for randomized, cohort, case-control, and case series studies evaluating adult patients requiring VA ECMO for cardiogenic shock. Five retrospective observational studies, representing 425 patients, were included. Venoarterial extracorporeal membrane oxygenation with concomitant Impella strategy was used in 27% of the patients. Median age across studies varied between 51 and 63 years with 59-88% patients being male. Use of ECPELLA was associated with higher weaning from VA ECMO and bridging to permanent ventricular assist device or cardiac transplant in three and four studies, respectively. The studies showed moderate heterogeneity with possible publication bias. The two studies that accounted for differences in baseline characteristics between treatment groups reported lower 30 day mortality with ECPELLA versus VA ECMO. The remaining three studies did not adjust for potential confounding and were at high risk for selection bias. In conclusion, ECPELLA is being increasingly used as a strategy in patients with cardiogenic shock. Additional large, high-quality studies are needed to evaluate clinical outcomes with ECPELLA.
Influence of Proton Activity Gaps between Electrodes on Open-Circuit Potential of H2/H2 and H2/Air Cells (2020)

In polymer electrolyte fuel cells, proton activity thermodynamically correlates with the relative humidity (RH) as well as water uptake (λ) of the ionomer electrolyte. Proton activity differences between the two electrodes arise from RH control, and the activity terms of the Nernst equation could become significant. We investigated the effect of proton activity on open-circuit potentials (OCPs) and cell performance by controlling the RH of H 2 /H 2 and H 2 /air cells, and on the kinetic current ( i k ) using a rotating disk electrode (RDE). In the H 2 /H 2 cell, OCPs were caused by the RH difference between electrodes; thermodynamic analysis was performed to rationalize the experimental OCP by correlating the RH and λ. The H 2 /air cell performance was low owing to the high resistance and low exchange current density at RH &lt; 30%. The RDE measurements showed that i k decreased with increasing concentrations (proton activities) of HClO 4 , H 2 SO 4 , and CF 3 SO 3 H (TFMSA).
Security of two quantum cryptography protocols using the same four qubit states (2005)

The first quantum cryptography protocol, proposed by Bennett and Brassard in 1984 (BB84), has been widely studied in recent years. This protocol uses four states (more precisely, two complementary bases) for the encoding of the classical bit. Recently, it has been noticed that by using the same four states, but a different encoding of information, one can define a protocol which is more robust in practical implementations, specifically when attenuated laser pulses are used instead of single-photon sources [V. Scarani et al., Phys. Rev. Lett. 92, 057901 (2004), referred to as the SARG04 protocol]. We present a detailed study of SARG04 in two different regimes. In the first part, we consider an implementation with a single-photon source: we derive bounds on the error rate $Q$ for security against all possible attacks by the eavesdropper. The lower and the upper bound obtained for SARG04 ($Q\ensuremath{\lesssim}10.95%$ and $Q\ensuremath{\gtrsim}14.9%$, respectively) are close to those obtained for BB84 ($Q\ensuremath{\lesssim}12.4%$ and $Q\ensuremath{\gtrsim}14.6%$, respectively). In the second part, we consider a realistic source consisting of an attenuated laser and improve on previous analysis by allowing Alice to optimize the mean number of photons as a function of the distance. The SARG04 protocol is found to perform better than BB84, both in secret-key rate and in maximal achievable distance, for a wide class of Eve's attacks.
Precision electrical trimming of very low TCR poly-SiGe resistors (2000)

Precision electrical trimming of stacked Si/SiGe polycrystalline resistors available from the extrinsic base structure of a SiGe BiCMOS technology has been demonstrated for the first time. It is shown that pulse current trimming techniques can be used to trim the poly-SiGe resistors by up to 50% from their original values with accuracy better than /spl plusmn/0.5%. The temperature coefficient of resistance (TCR) is shown to be linearly proportional to the percent change in electrically trimmed poly-SiGe resistance. Finally, we demonstrate resistance cycling using an electrical trim/recovery sequence, indicating that the technique is reversible and is governed by dopant segregation/diffusion mechanisms. The results are consistent with those obtained on conventional polysilicon resistors suggesting that the introduction of a strained SiGe layer does not adversely affect the electrical trim properties of these resistors.
SYSTEMS ENGINEERING FRAMEWORK FOR IMPLEM A SECURITY AND CRITI CAL PATCH MANAGEMENT ENVIRONMENTS (ACADEM IC DEPARTMENTS WORKSTATIONS) (2013)

In any networked computing system, particularly in an academic environment, it is not uncommon to administer workstations that have been compromised because of security vul nerabilities and viruses in the operating system or in the software packages that are installed. Applying the Security and Critical Patch Management Process (SCPMP) described in this study at an early stage in a computing system can mitigate the risk of at tack as well as decrease the cost of Information Technology (IT) operations. In this paper we propose an optimal systems engineering (SE) framework to improve the current patch management process framework, to prevent an organization's networked computer s ystems from becoming the target of vulnerabilities that are immediately exploitable and could lead to critical system failure or compromised security. The proposed SE framework comprises a new mechanism for IT Operational Activities that increases network critical systems integration. By exerting SE principles with considerable influence on patching, IT departments can manipulate the SCPMP framework to meet patch management requirements, estimate the stages of the SCPMP performance, ne an affordable portfolio. This article details a patch management framework design and the preliminary implementation of the SCPMP in an academic environment. The focus is on measuring variations in the components of a full the data collected from implementing the process in an academic department's workstations as a case study, using Maintenance Optimizing Tools.
Spatial‐temporal variability of soil moisture and its estimation across scales (2010)

The soil moisture is a quantity of paramount importance in the study of hydrologic phenomena and soil‐atmosphere interaction. Because of its high spatial and temporal variability, the soil moisture monitoring scheme was investigated here both for soil moisture retrieval by remote sensing and in view of the use of soil moisture data in rainfall‐runoff modeling. To this end, by using a portable Time Domain Reflectometer, a sequence of 35 measurement days were carried out within a single year in seven fields located inside the Vallaccia catchment, central Italy, with area of 60 km 2 . Every sampling day, soil moisture measurements were collected at each field over a regular grid with an extension of 2000 m 2 . The optimization of the monitoring scheme, with the aim of an accurate mean soil moisture estimation at the field and catchment scale, was addressed by the statistical and the temporal stability. At the field scale, the number of required samples (NRS) to estimate the field‐mean soil moisture within an accuracy of 2%, necessary for the validation of remotely sensed soil moisture, ranged between 4 and 15 for almost dry conditions (the worst case); at the catchment scale, this number increased to nearly 40 and it refers to almost wet conditions. On the other hand, to estimate the mean soil moisture temporal pattern, useful for rainfall‐runoff modeling, the NRS was found to be lower. In fact, at the catchment scale only 10 measurements collected in the most “representative” field, previously determined through the temporal stability analysis, can reproduce the catchment‐mean soil moisture with a determination coefficient, R 2 , higher than 0.96 and a root‐mean‐square error, RMSE, equal to 2.38%. For the “nonrepresentative” fields the accuracy in terms of RMSE decreased, but similar R 2 coefficients were found. This insight can be exploited for the sampling in a generic field when it is sufficient to know an index of soil moisture temporal pattern to be incorporated in conceptual rainfall‐runoff models. The obtained results can address the soil moisture monitoring network design from which a reliable soil moisture temporal pattern at the catchment scale can be derived.
Radioactivity of the Columbia River Effluent (1965)

Chromium-51 and zinc-65 were detected as far as 115 and 15 kilometers, respectively, from the mouth of the Columbia River; zinc-65 also was found at a few isolated stations. Zirconium-95 and niobium-95 from atmospheric fallout occurred in the river effluent but they were most abundant in surface waters further ofJshore. Distribution of the radionuclides is controlled largely by surface currents and by upwelling of sea water near the coast.
Two-dimensional polymer photonic crystal band-edge lasers fabricated by nanoimprint lithography (2007)

We report on the fabrication and characterization of two-dimensional polymer photonic crystal band-edge lasers operating in the visible range. The components have been fabricated in a dye chromophore-loaded polymer matrix by nanoimprint lithography. High-symmetry band-edge modes are used to generate laser emission. The experimental lasing frequencies are in good agreement with those calculated using a two-dimensional plane wave algorithm. These results demonstrate the potential of nanoimprint lithography for the fabrication of two-dimensional planar photonic crystal structures in an active medium in a one-step process.(C) 2007 American Institute of Physics.

A Wearable ECG Acquisition System With Compact Planar-Fashionable Circuit Board-Based Shirt (2009)

A wearable electrocardiogram (ECG) acquisition system implemented with planar-fashionable circuit board (P-FCB)-based shirt is presented. The proposed system removes cumbersome wires from conventional Holter monitor system for convenience. Dry electrodes screen-printed directly on fabric enables long-term monitoring without skin irritation. The ECG monitoring shirt exploits a monitoring chip with a group of electrodes around the body, and both the electrodes and the interconnection are implemented using P-FCB to enhance wearability and to lower production cost. The characteristics of P-FCB electrode are shown, and the prototype hardware is implemented to successfully verify the proposed concept.
Silicon Nitride Joining Using Silica and Yttria Ceramic Interlayers (2002)

Dense hot‐pressed β‐Si 3 N 4 blocks were joined using both SiO 2 and SiO 2 ‐Y 2 O 3 powder slurries as bonding interlayers. The assembled specimens (Si 3 N 4 /interlayer/Si 3 N 4 ) were heated in a flowing N 2 atmosphere in the temperature range of 1500°–1650°C. The joining interlayer was clearly distinguished from the Si 3 N 4 bulk. The microstructure and the reaction products found in the bonding interlayer were very different in both compositions. Reactions occurring between the Si 3 N 4 and the ceramic joining compositions have been explained based on existing diagrams of the YN–Si 3 N 4 ‐Y 2 O 3 ‐SiO 2 system.
