In situ deposition of epitaxial PZT films by pulsed laser deposition (2004)

Pb(Zr<sub>x</sub>Ti<sub>1-x</sub>)O<sub>3</sub> (PZT) thin films were in situ-grown on Pt/Ti/SiO<sub>2</sub>/Si substrates by a hybrid process consisting of the sol-gel method and pulsed-laser deposition (PLD). The deposition temperature to obtain the perovskite phase in the hybrid process is 460°C, and is significantly lower than that in the case of direct film deposition by PLD on a Pt/Ti/SiO<sub>2</sub>/Si substrate. X-ray diffraction analysis indicated that the preferred orientation of PZT films can be controlled using the layer deposited by the sol-gel method and highly (111)- or (100)-oriented PZT films were obtained. A transmission electron microscopy (TEM) image showed that the film had a polycrystalline columnar microstructure extending through its thickness, and no sharp boundary was observed between the layers deposited by the sol-gel method and PLD. A high-resolution electron microscopy image and electron diffraction analysis revealed that the crystalline lattice of the layers deposited by the sol-gel method and PLD was continuous and there was no difference in crystalline orientation between the layers. These results indicate that the solid-phase epitaxial effect between the PZT layers deposited by the sol-gel method and PLD decreases the deposition temperature to obtain the perovskite phase during PLD, and causes the films to exhibit the same preferred orientation as that of the layer deposited by the sol-gel method. The dielectric constant and remanent polarization of the films in situ deposited at 460°C were approximately 900 and 15 &amp;mu;C/cm<sup>2</sup>, respectively.
Intensity versus texture for medical image search and retrival (2008)

The ever-increasing number of digital images in the medical domain, has amplified the need for automated search and retrieval tools. Furthermore, medical experts generally focus on specific anatomical structures to identify the cause of a pathology. For such cases, automated tools that can retrieve relevant slice(s) from a patient's image volume can assist the expert in diagnosis. Accordingly, in this paper we introduce a new search and retrieval work for finding relevant slices in brain MR (magnetic resonance) volumes. The features explored in this framework are based on intensity, texture, and their extended versions complemented with spatial context. Experiments on real data revealed that texture information outperformed its intensity counterpart, incorporating spatial context in the features substantially improved the accuracy, and finally texture features with spatial context provided fast and highly accurate retrieval of relevant slices.
Restoring Host-Microbe Homeostasis via Selective Chemoattraction of Tregs (2014)

The disruption of host-microbe homeostasis at the site of periodontal disease is considered a key factor for disease initiation and progress. While the downstream mechanisms responsible for the tissue damage per se are relatively well-known (involving various patterns of immune response operating toward periodontal tissue destruction), we are only beginning to understand the complexity of host-microbe interactions in the periodontal environment. Unfortunately, most of the research has been focused on the disruption of host-microbe homeostasis instead of focusing on the factors responsible for maintaining homeostasis. In this context, regulatory T-cells (Tregs) comprise a CD4+FOXp3 +T-cell subset with a unique ability to regulate other leukocyte functions to avoid excessive immune activation and its pathological consequences. Tregs act as critical determinants of host-microbe homeostasis, as well as determinants of a balanced host response after the disruption of host-microbe homeostasis by pathogens. In periodontitis, Tregs play a protective role, with their natural recruitment being responsible for conversion of active into inactive lesions. With controlled-release technology, it is now possible to achieve a selective chemoattraction of Tregs to periodontal tissues, attenuating experimental periodontitis evolution due to the local control of inflammatory immune response and the generation of a pro-reparative environment.
A transverse oscillation approach for estimation of three-dimensional velocity vectors, Part II: experimental validation (2014)

The 3-D transverse oscillation method is investigated by estimating 3-D velocities in an experimental flow-rig system. Measurements of the synthesized transverse oscillating fields are presented as well. The method employs a 2-D transducer; decouples the velocity estimation; and estimates the axial, transverse, and elevation velocity components simultaneously. Data are acquired using a research ultrasound scanner. The velocity measurements are conducted with steady flow in sixteen different directions. For a specific flow direction with [α, ß] = [45, 15]°, the mean estimated velocity vector at the center of the vessel is (v(x), v(y), v(z)) = (33.8, 34.5, 15.2) ± (4.6, 5.0, 0.6) cm/s where the expected velocity is (34.2, 34.2, 13.0) cm/s. The velocity magnitude is 50.6 ± 5.2 cm/s with a bias of 0.7 cm/s. The flow angles α and ß are estimated as 45.6 ± 4.9° and 17.6 ± 1.0°. Subsequently, the precision and accuracy are calculated over the entire velocity profiles. On average for all direction, the relative mean bias of the velocity magnitude is -0.08%. For α and ß, the mean bias is -0.2° and -1.5°. The relative standard deviations of the velocity magnitude ranges from 8 to 16%. For the flow angles, the ranges of the mean angular deviations are 5° to 16° and 0.7° and 8°.

Visualization of stress level cardiac functional (2008)

&lt;p&gt;The invention relates to a system (100) for visualizing a cardiac parameter at a plurality of positions in a myocardium and at a plurality of stress levels, the system comprising a determination unit (110) for determining a value of the cardiac parameter at a position from the plurality of positions in the myocardium and at a stress level from the plurality of stress levels on the basis of stress level cardiac functional data, and a visualization unit (120) for visualizing the determined value of the cardiac parameter by displaying a point in a viewing plane. The visualized points are defined by their polar coordinates in a polar coordinate system in the viewing plane. A radial coordinate of the point visualizes the determined value of the cardiac parameter. An angular coordinate of the point visualizes an angular coordinate of the position in the myocardium in a cylindrical coordinate system. Thus, the system allows easy numerical comparison of local myocardial contractions at different stress level values.&lt;/p&gt;
Static determination of allocation rates to support real-time garbage collection (2005)

While it is generally accepted that garbage-collected languages offer advantages over languages in which objects must be explicitly deallocated, real-time developers are leery of the adverse effects a garbage collector might have on real-time performance. Semiautomatic approaches based on regions have been proposed, but incorrect usage could cause unbounded storage leaks or program failure. Moreover, correct usage cannot be guaranteed at compile time. Recently, real-time garbage collectors have been developed that provide a guaranteed fraction of the CPU to the application, and the correct operation of those collectors has been proven, subject only to the specification of certain statistics related to the type and rate of objects allocated by the application. However, unless those statistics are provided or estimated appropriately, the collector may fail to collect dead storage at a rate sufficient to pace the application's need for storage. Overspecification of those statistics is safe but leaves the application with less than its possible share of the CPU, which may prevent the application from meeting its deadlines.In this paper we present a static analysis to bound conservatively an application's allocation rate . The analysis is based on a data flow framework that requires interprocedural evaluation. We present the framework and results from analyzing some Java benchmarks. Because static analysis is necessarily conservative, we also present measurements of our benchmarks' actual allocation rates.Our work is a necessary step toward making real-time garbage collectors attractive to the hard-real-time community. By guaranteeing a bound on statistics provided to a real-time collector, we can guarantee the operation of the collector for a given application.
A Simple and Wideband Decoupling Method for Antenna Array Applications (2020)

In this work, a simple wavetrap-based decoupling method is proposed to suppress the mutual coupling among the antenna elements in a single antenna array. The proposed wavetrap structure consists of a transmission line and a resistor which are in series. By placing two wavetraps between two patch antennas, the isolation between the two corresponding ports can be significantly improved over a wide frequency band. Theoretical analyses and full-wave simulations are carried out to verify the decoupling performance of the proposed method. The results show that the proposed approach features well-designed decoupling characteristics, and can be widely used for largescale arrays.
Plasma unbound free fatty acid profiles in premature infants before and after intralipid infusion (2018)

Background: Unbound free fatty acids (FFAu) are the bioactive fraction of plasma free fatty acids (FFA). Most plasma FFA are bound to albumin. Only when FFA dissociate from albumin, do they become biologically active.Objective: To measure the first FFAu profiles in human infants and to measure these profiles before and during intravenous administration of the soybean lipid, intralipid (IL).Study design: The study population was 16 premature infants, from a parent study of 130 infants with birth weights 500–2000 g and gestational age 23–34 weeks. The infants chosen had plasma samples of ≥120 µL (volume needed for each FFAu profile measurement) in the first day of life. Infants received IL infusions starting in the second day of life at 1 g/kg/day, increasing by 1-g/kg/day daily up to 3 g/kg/day. FFAu profiles were determined during IL infusion when plasma was available. Profiles are the concentrations of the nine most abundant long-chain FFAu and were determined using novel fluorescent probes.Results: Before intralipid infusion unbound myristic acid was the dominant FFAu, as high as 78% of the total FFAu (sum of the 9 FFAu). In contrast, unbound linoleic acid was 0% in all infants. With increasing infusion of IL to 3 g/kg/day, unbound linoleic increased to 26% of the total FFAu, with unbound oleic, myristic, and linolenic acid the second, third and fourth most abundant. The average total FFAu concentration also increased from 4 nM before intralipid to 53 nM at 3 g/kg/day. During IL infusion the FFAu profiles approached the fatty acid composition of intralipid at 3 g/kg/day.Conclusions: This first study of FFAu profiles in neonates revealed that before IL infusion unbound linoleic acid was zero in all 16 infants and levels of myristic acid were exceptionally large, as much as 78% of the total FFAu profile. These results suggest important and previously unrecognized roles of lipid metabolism in early development. Zero unbound linoleic acid before IL infusion may help promote closure of the ductus arteriosus but after IL infusion, synthesis of arachidonic from linoleic acid may tend to promote patency. The high levels of unbound myristate may be needed for immediate neonatal energy needs.
Induction of Various HLA Class II Molecules in a Human Colonic Adenocarcinoma Cell Line (1987)

The colonic carcinoma cell line HT-29 had no constitutive expression of HLA class II molecules. Gamma interferon (IFN-gamma) induced expression of HLA class II molecules in a dose-dependent manner with 100 U/ml as an optimal dose. The expression of HLA-DR, HLA-DP, and HLA-DQ molecules seemed to follow different kinetics. While DR and DP molecules were maximally induced after 2 days, DQ molecules appeared later with maximum percentage positive cells after 8 days. Treatment with a prostaglandin synthesis inhibitor (indomethacin) neither induced class II expression nor altered the dose-response curve for IFN-gamma; this indicated that possible endogenous production of prostaglandins in this cell line did not interfere with its class II expression. The lectins phytohaemagglutinin (PHA), concanavalin A (Con A), pokeweed mitogen (PWM), and wheat germ agglutinin (WGA) did not induce class II expression.
Mapping cardiopulmonary dynamics within the microvasculature of the lungs using dissolved 129Xe MRI (2020)

Magnetic resonance (MR) imaging and spectroscopy using dissolved hyperpolarized (HP) <sup>129</sup>Xe have expanded the ability to probe lung function regionally and noninvasively. In particular, HP <sup>129</sup>Xe imaging has been used to quantify impaired gas uptake by the pulmonary tissues. Whole-lung spectroscopy has also been used to assess global cardiogenic oscillations in the MR signal intensity originating from <sup>129</sup>Xe dissolved in the red blood cells of pulmonary capillaries. Herein, we show that the magnitude of these cardiogenic dynamics can be mapped three dimensionally using radial MRI, because dissolved <sup>129</sup>Xe dynamics are encoded directly in the raw imaging data. Specifically, 1-point Dixon imaging is combined with postacquisition keyhole image reconstruction to assess regional blood volume fluctuations within the pulmonary microvasculature throughout the cardiac cycle. This "oscillation mapping" was applied in healthy subjects (mean amplitude 9% of total RBC signal) and patients with pulmonary arterial hypertension (PAH; mean 4%) and idiopathic pulmonary fibrosis (IPF; mean 14%). Whole-lung mean values from these oscillation maps correlated strongly with spectroscopy and clinical pulmonary function testing, but exhibited significant regional heterogeneity, including gravitationally dependent gradients in healthy subjects. Moreover, regional oscillations were found to be sensitive to disease state. Greater percentages of the lungs exhibit low-amplitude oscillations in PAH patients, and longitudinal imaging shows high-amplitude oscillations increase significantly over time (4-14 mo, <i>P</i> = 0.02) in IPF patients. This technique enables regional dynamics within the pulmonary capillary bed to be measured, and in doing so, provides insight into the origin and progression of pathophysiology within the lung microvasculature.<b>NEW & NOTEWORTHY</b> Spatially heterogeneous abnormalities within the lung microvasculature contribute to pathology in various cardiopulmonary diseases but are difficult to assess noninvasively. Hyperpolarized <sup>129</sup>Xe MRI is a noninvasive method to probe lung function, including regional gas exchange between pulmonary air spaces and capillaries. We show that cardiogenic oscillations in the raw dissolved <sup>129</sup>Xe MRI signal from pulmonary capillary red blood cells can be imaged using a postacquisition reconstruction technique, providing a new means of assessing regional lung microvasculature function and disease state.
Pulse front adaptive optics in two-photon microscopy (2015)

Adaptive optics has been extensively studied for the correction of phase front aberrations in optical systems. In systems using ultrafast lasers, distortions can also exist in the pulse front (contour of constant intensity in space and time), but until now their correction has been mostly unexplored due to technological limitations. In this Letter, we apply newly developed pulse front adaptive optics, for the first time to our knowledge, to practical compensation of a two-photon fluorescence microscope. With adaptive correction of the system-induced pulse front distortion, improvements beyond conventional phase correction are demonstrated.
Strains of Hong Kong Influenza Virus in Calves (1977)

Three strains of Hong Kong influenza virus isolated from humans were compared with a strain isolated from a calf for their ability to cause disease in calves. One of the human strains. A/Aichi/2/68, was detected for five days in a calf, but all three failed to cause signs of disease. Strain A/cal/Duschanbe/55/71 could be detected for seven days and caused an influenza-like illness in calves.
Ovarian Vein Embolization for Pelvic Congestion Syndrome (2000)

Pelvic congestion syndrome is a controversial entity consisting of varying degrees of pelvic heaviness or pain caused by retrograde flow in one or both ovarian veins. It has to date been unevenly accepted by clinicians and relatively poorly studied. Nevertheless, approximately 50% of patients with otherwise unexplained pelvic pain have ovarian vein reflux and 73.7 to 88.9% of women have symptomatic improvement after ovarian vein embolization.
Computational studies of solid-state alkali conduction in rechargeable alkali-ion batteries (2016)

The facile conduction of alkali ions in a crystal host is of crucial importance in rechargeable alkali-ion batteries, the dominant form of energy storage today. In this review, we provide a comprehensive survey of computational approaches to study solid-state alkali diffusion. We demonstrate how these methods have provided useful insights into the design of materials that form the main components of a rechargeable alkali-ion battery, namely the electrodes, superionic conductor solid electrolytes and interfaces. We will also provide a perspective on future challenges and directions. The scope of this review includes the monovalent lithium- and sodium-ion chemistries that are currently of the most commercial interest. Scientists have assessed the vital contributions computational approaches have made to the study of alkali ion flow in alkali-ion batteries. Ubiquitous lithium-ion batteries are currently the dominant means of powering consumer electronic devices, while sodium-ion batteries are enjoying a resurgence. Alkali ion transport in the components (electrodes, electrolyte and their interface) of such batteries strongly affects their performance, but the factors affecting it are not well understood. Zhi Deng of the University of California and co-authors note that computational methods for analysing the flow of alkali ions in alkali-ion batteries provide valuable insights for enhancing battery performance. They review the computational methods available, outlining their advantages and limitations, and discuss how such methods have advanced the understanding and design of battery components. Finally, the researchers mention current challenges and possible future developments in this field. The facile conduction of alkali ions in a crystal host is of crucial importance in rechargeable alkali-ion batteries. This review provides a comprehensive survey of the various computational approaches, such as transition state, molecular dynamics and Monte Carlo methods, to study solid-state alkali diffusion, discusses how these methods have provided useful insights into the design of crystalline materials that form the main components of a rechargeable alkali-ion battery, namely the electrodes, superionic conductor solid electrolytes and their interfaces, and provides our perspective on the future challenges and directions in computational alkali diffusion studies.

Magneto-Volume and Tetragonal Elongation Effects on Magnetic Phase Transitions of Body-Centered Tetragonal FeRh1-xPtx (1994)

Magnetic properties of FeRh 1- x Pt x system with body-centered cubic and body-centered tetragonal (bct) structures were studied by means of X-ray diffractometry, magnetometry and Mössbauer spectroscopy, and the phase diagram in a temperature-composition plane was determined. With substituting Pt for Rh, the axial ratio c / a was increased and the bct phase was stabilized. With increasing temperature, the bct alloys with 0.72< x <0.81 underwent a first-order phase transition from the antiferromagnetic state to the ferromagnetic state, while the alloys with 0.3< x <0.72 exhibited a first-order phase transition from the antiferromagnetic state to the paramagnetic state with a volume expansion and a tetragonal lattice distortion. The mechanism of those phase transitions was discussed in terms of the magneto-volume and the tetragonal elongation effect.
Long-term monitoring of soil fertility for agroforestry combined with water harvesting in Central Chile (2012)

Agroforestry associated with water harvesting was evaluated in field experiments conducted in central Chile, 1996–2008. Soil fertility parameters, such as soil organic matter (SOM), soil reaction (pH), total nitrogen (NT), total phosphorus (PT) and total potassium (KT) contents were measured for five different treatments: control (C), agroforestry (A), agroforestry with water harvesting (AR), woody perennial (W) and woody perennial with water harvesting (WR). Acacia saligna was used as the woody perennial component. Treatments, including Acacia saligna (A, AR, W and WR) increased SOM and NT stocks over time compared with the control, probably due to higher SOM and N inputs from the litter and root turnover. The treatments with water harvesting (AR and WR) showed the highest SOM and NT contents by 2008, suggesting that this practice had positive effects on water infiltration rates and soil water content in the soil, important parameters in the process of root turnover. However, there were no significant differences in other soil parameters, such as pH, PT and KT, perhaps due to the short study time, and soil spatial and temporal variability between treatments.
