Electrical Properties and Microstructures of Sol-Gel-Deposited Lead Zirconate Titanate Thin Films Crystallized by 28 GHz Microwave Irradiation (2005)

Pb(Zr x Ti 1- x )O 3 (PZT) thin films were coated on Pt/Ti/SiO 2 /Si substrates by a sol-gel method and then crystallized by 28 GHz microwave irradiation. The crystalline phases and microstructures as well as the electrical properties of the microwave-irradiated PZT films were investigated as a function of the elevated temperature generated by microwave irradiation. X-ray diffraction analysis indicated that the PZT films crystallized well into the perovskite phase at an elevated temperature of 480°C by microwave irradiation. Scanning electron microscopy images showed that the films had a granular grain structure and most of the grains were approximately 1.5 µm in size. With increasing elevated temperature from 480°C to 600°C by microwave irradiation, the breadth of grain boundaries of the films became narrow and the remanent polarization of the films increased slightly. It is clear that microwave irradiation is effective for obtaining well-crystallized PZT films with good properties at low temperatures in a short time.
The P-Band Space Exploration Synthetic Aperture Radar (SESAR) (2023)

The Space Exploration Synthetic Aperture Radar (SESAR) is a P-band (435 MHz) radar instrument for planetary applications capable of measuring the surface and subsurface of planetary bodies at full polarimetry and at meter-scale resolution. These measurements can reveal important information about the surface evolution and geologic history of the planetary bodies, and help identify buried resources for future explorers. SESAR's architecture is based on a low power, lightweight, beamforming design, specifically developed to meet stringent requirements of planetary instruments. The SESAR developmental effort, carried out at NASA/GSFC, designed and built a prototype SAR instrument, and environmentally tested it, with the goal of maturing the SESAR technology readiness level for upcoming planetary mission opportunities.

The 5G CONNI Europe-Taiwan project investigates innovative solutions for Private 5G and beyond Network. This includes the definition of new architectures and measurements tools as well as, the development of innovative technologies and their enabling components in the context of mobile edge assisted URLLC. Building on the premise of Private 5G Networks, the 5G CONNI project will offer an unprecedented integrated end-to-end 5G testing network for testing specifically industrial applications in accordance with updated 5G standardization specifications. The 5G CONNI project will validate its innovative and technologically advanced solutions and components with a real-field cross-continental end-to-end industrial Private 5G Network demonstration between two interconnected industrial manufacturing sites in Taiwan and in Europe.
Microemulsions supported by octyl monoglucoside and geraniol. 3. Microstructure & general pattern (2023)

This paper completes previous studies on the phase behaviour and microstructure of the quaternary microemulsion water – cyclohexane – n-octyl-β-D-glucoside (β-C8G1) – geraniol. The properties of this system are almost insensitive to temperature, while they can be tuned easily by adding an alcohol as co-surfactant. The addition of the alcohol changes the composition of the interfacial film, which, in turn, is the tuning parameter for the quaternary system. Studies of the phase behaviour together with SANS and NMR measurements allow drawing a quantitative picture of how the domain size ξ, the curvature H, and the interfacial tension σab depend on the composition of the interfacial film. The SANS data of both oil-in-water and water-in-oil droplet microemulsions recorded near the emulsification failure boundary were evaluated with the Generalised Indirect Fourier Transformation (GIFT), revealing a growth towards cylindrical structures when approaching the respective critical end point. We will show that the general behaviour of ternary and quaternary systems is equal if the appropriate tuning parameters are chosen. In addition, we will show that it is possible to apply the scaling description derived for temperature-dependent ternary systems to composition-dependent quaternary systems: plotting the reduced domain size, the reduced curvature and the reduced interfacial tension against the proper reduced tuning parameter, i.e., either the reduced temperature or the reduced interfacial composition, leads to one master curve for all systems.
Non-Blocking Operation of a Tunable Compact Optical Filter with Large FSR (2011)

We fabricate and characterize a CMOS-compatible, Mach-Zehnder-coupled, 2nd-order-ring-resonator filter with doubled free spectral range and demonstrate non-blocking operation while tuning it to a new wavelength.
Dilatation in anastomosed arteries can be an artifact of explantation (1992)

Fusiform dilation of the anastomotic site was found at explantation in the majority of rabbit femoral arteries anastomosed with newly developed microclips. This observation was also noted at sutured anastomoses. The mechanism responsible for this morphologic finding was studied by the following experiments: 1) measuring and explanting anastomosed arteries relaxed with 20% lidocaine, 2) latex casts of microclipped arteries, 3) comparing angiographic and histologic morphometric data, and 4) examining synthetic vascular graft anastomoses with identical dilatation. The observations demonstrate that trauma associated with explantation (direct dissection and fixative perfusion) leads to arterial vasoconstriction, but focal medial damage at the anastomotic site prevents constriction at this site.
N-Dimensional Path Optimization: The Implementation of a Novel Algorithm in ITK (2005)

Using the path framework we previously added to ITK, we implemented a novel algorithm for n-dimensional path optimization, which we call the ND Swath (NDS). NDS uses dynamic programming to globally optimize the placement of a path within an image, subject to several constraints and a user-supplied merit function. The NDS algorithm is presented in this paper along with a description of how it was implemented using ITK.
Force-Controlled Formation of Dynamic Nanopores for Single-Biomolecule Sensing and Single-Cell Secretomics (2020)

Nanopore sensing of single nucleotides has emerged as a promising single-molecule technology for DNA sequencing and proteomics. Despite the conceptual simplicity of nanopores, adoption of this technology for practical applications has been limited by a lack of pore size adjustability and an inability to perform long-term recordings in complex solutions. Here we introduce a method for fast and precise on-demand formation of a nanopore with controllable size between 2 and 20 nm through force-controlled adjustment of the nanospace formed between the opening of a microfluidic device (made of silicon nitride) and a soft polymeric substrate. The introduced nanopore system enables stable measurements at arbitrary locations. By accurately positioning the nanopore in the proximity of single neurons and continuously recording single-molecule translations over several hours, we have demonstrated this is a powerful approach for single-cell proteomics and secretomics.
Panel 6: Vaccines (2017)

Objective To review the literature on progress regarding (1) effectiveness of vaccines for prevention of otitis media (OM) and (2) development of vaccine antigens for OM bacterial and viral pathogens. Data Sources PubMed database of the National Library of Science. Review Methods We performed literature searches in PubMed for OM pathogens and candidate vaccine antigens, and we restricted the searches to articles in English that were published between July 2011 and June 2015. Panel members reviewed literature in their area of expertise. Conclusions Pneumococcal conjugate vaccines (PCVs) are somewhat effective for the prevention of pneumococcal OM, recurrent OM, OM visits, and tympanostomy tube insertions. Widespread use of PCVs has been associated with shifts in pneumococcal serotypes and bacterial pathogens associated with OM, diminishing PCV effectiveness against AOM. The 10‐valent pneumococcal vaccine containing Haemophilus influenzae protein D (PHiD‐CV) is effective for pneumococcal OM, but results from studies describing the potential impact on OM due to H influenzae have been inconsistent. Progress in vaccine development for H influenzae, Moraxella catarrhalis , and OM‐associated respiratory viruses has been limited. Additional research is needed to extend vaccine protection to additional pneumococcal serotypes and other otopathogens. There are likely to be licensure challenges for protein‐based vaccines, and data on correlates of protection for OM vaccine antigens are urgently needed. Implications for Practice OM continues to be a significant health care burden globally. Prevention is preferable to treatment, and vaccine development remains an important goal. As a polymicrobial disease, OM poses significant but not insurmountable challenges for vaccine development.

The Importance of Grain Boundaries for the Time-Dependent Mobility Degradation in Organic Thin-Film Transistors (2009)

The relationships between organic semiconductor morphology and device stability of organic field-effect transistors (FETs) are very complex and not yet fully understood. Especially for obtaining high-performance, air-stable n-channel FETs, gaining a deep insight into possible degradation mechanisms can help improve their air stability. Here, we investigate the performance and stability of organic n-channel FETs based on solution-grown single-crystalline ribbons of the conjugated semiconductor bis(1H,1H-perfluorobutyl)-dicyano-perylene tetracarboxylic diimide (C3F7CH2−PTCDI-(CN)2). The FETs show an electron mobility of 0.25 cm2/(V s) in air and an on/off ratio up to 1 × 107. Their mobility does not significantly change when devices are stored in air for more than 5 weeks. This excellent air stability stands in contrast to FETs based on thin evaporated polycrystalline films of the same compound that degrade by more than an order of magnitude during the same 5 week period. We attribute this striking difference in air stability to the grain boundaries in the polycrystalline films and discuss different possible degradation mechanisms.
[Serotonin uptake inhibitors provide rapid relief from premenstrual dysphoria. New findings shed light on how serotonin modulates sex hormone-related behavior]. (2001)

Premenstrual dysphoria (PMD) is a severe form of premenstrual syndrome, afflicting 5-10% of all women. The cardinal symptom--surfacing between ovulation and menstruation, and disappearing within a few days after the onset of the bleeding--is irritability. Serotonin reuptake inhibitors (SRIs), but not non-serotonergic antidepressants, reduce the symptoms of PMD very effectively. Since the, onset of action of SRIs is rapid when used for PMD, medication may be restricted to the luteal phase. The finding that SRIs are effective for PMD lends support for the hypothesis that a major role for brain serotonin is to modulate sex steroid-driven behavior.
Stereo in the presence of specular reflection (2002)

The problem of accurate depth estimation using stereo in the presence of specular reflection is addressed. Specular reflection, a fundamental and ubiquitous reflection mechanism, is viewpoint dependent and can cause large intensity differences at corresponding points, resulting in significant depth errors. We analyze the physics of specular reflection and the geometry of stereopsis which led us to a relationship between stereo vergence, surface roughness, and the likelihood of a correct match. Given a lower bound on surface roughness, an optimal binocular stereo configuration can be determined which maximizes precision in depth estimation despite specular reflection. However, surface roughness is difficult to estimate in unstructured environments. Therefore, trinocular configurations, independent of surface roughness, are determined such that at each scene point visible to all sensors, at least one stereo pair can compute produce depth. We have developed a simple algorithm to reconstruct depth from the multiple stereo pairs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Assessing the Appropriate Number of Days Needed to Approximate Physical Activity Level in the Active Elderly (2009)

Activity monitoring is an important consideration for a number of conditions associated with health maintenance in an aging population. For example, reduced bone mineral density (BMD) in the aging population puts this group at a higher risk of fall related fractures [1]. Bone density and bone health is in part dependent upon mechanical stimuli caused by everyday physical activity and loading [2]. The number of steps taken per day and walking velocity [3] are important parameters to consider when studying bone density as well as other health related conditions. However, there is a need for effective and efficient methods/protocols to ensure that representative daily activity data can be collected.

4.7 A sub-ns response on-chip switched-capacitor DC-DC voltage regulator delivering 3.7W/mm2 at 90% efficiency using deep-trench capacitors in 32nm SOI CMOS (2014)

For an on-chip or fully integrated microprocessor power-delivery system, the on-chip power converter must 1) be designed using the same technology as the microprocessor, 2) deliver high power density to supply a microprocessor core with small area overhead, 3) achieve high efficiency, and 4) perform fast regulation over a wide voltage range for dynamic voltage and frequency scaling (DVFS). On-chip switched-capacitor (SC) converters have gained increasing popularity for this application due to their ease of integration using only transistors and capacitors readily available in the chosen technologies [1-6].
In vivo regulation of plasminogen function by plasma carboxypeptidase B (2002)

The major functions of plasminogen (Plg) in fibrinolysis and cell migration depend on its binding to carboxy-terminal lysyl residues. The ability of plasma carboxypeptidase B (pCPB) to remove these residues suggests that it may act as a suppressor of these Plg functions. To evaluate this role of pCPB in vivo, homozygote pCPB-deficient mice were generated by homologous recombination, and the resulting pCPB(-/-) mice, which were viable and healthy, were mated to Plg(-/-) mice. Plg(+/-) mice show intermediate levels of fibrinolysis and cell migration compared with Plg wild-type and deficient mice, reflecting the intermediate levels of the Plg antigen in their plasma. Differences in Plg-dependent functions between pCPB(+/+), pCPB(+/-), and pCPB(-/-) mice were then analyzed in a Plg(+/-) background. In a pulmonary clot lysis model, fibrinolysis was significantly increased in mice with partial (pCPB(+/-)) or total absence (pCPB(-/-)) of pCPB compared with their wild-type counterparts (pCPB(+/+)). In a thioglycollate model of peritoneal inflammation, leukocyte migration at 72 hours increased significantly in Plg(+/-)/pCPB(+/-) and Plg(+/-)/pCPB(-/-) compared with their wild-type counterparts. These studies demonstrate a definitive role of pCPB as a modulator of the pivotal functions of Plg in fibrinolysis and cell migration in vivo.
Controlling the Near-Field of Metasurfaces for Free-Electron Multi-Harmonic Hard X-Ray Generation (2018)

Metasurfaces are subwavelength spatial variations in geometry and material, and offer us an ingenious way of manipulating far-field radiation. Here, we show that their ability to manipulate the near-field is also an extremely powerful lever in controlling nanophotonic photon-electron interactions. The metasurface near-field contains high-order spatial harmonics that can be leveraged to generate substantial high harmonic components, whose properties are directly tunable through the metasurface geometry, the electron energy and the incidence angle of the input laser. By developing an analytical theory that produces results in excellent agreement with our ab initio simulations, we show how the design of metasurface-enhanced plasmons can be leveraged to produce intense and highly-directional multi-harmonic emission in the X-ray and the gamma-ray range. Furthermore, we show that the use of few-cycle laser pulses is instrumental in enhancing the intensity and bandwidth of the radiation output while avoiding damage to the metasurface. As an example, we present the design of a four-color X-ray source.
Abstract 16352: Temporal Trends in Mortality and Adverse Events in 24,890 Patients Undergoing Lead Extraction Over a Decade (2013)

Background: Despite the increasing number of pacemaker and defibrillator lead extractions, it is unclear whether lead extraction has become a safer procedure. We assessed the temporal trends in number of lead extractions performed and the associated rates of mortality and major adverse events (MAE) between the years of 2000 and 2011 in a large cohort of patients based on an administrative dataset. Methods: Hospital records were obtained from the California state agency for the years 2000-2011. Admissions including the ICD-9 CM procedure codes 37.75, 37.76 or 37.77 (lead extraction) were analyzed. MAE included cardiac tamponade, hemothorax and emergent cardiac surgery. The rates of in-hospital MAE and death were estimated using univariate and multivariate binomial mixed effects model with random effects terms for hospital, state and fixed effect terms for demographics and comorbid conditions. Results: 24,890 hospital discharges included the diagnosis lead extraction (Age 43.2 ± 0.14, male 40.9%, white 53.3%). Between 2000 to 2011 there was an increase in the number of lead extractions (2000: n = 1661; 2011: n = 2106) with decrease in the number of hospitals performing lead extraction (2000: n= 255; 2011: n = 215). There was an increase in the rates of MAE and death associated with lead extraction increased between 2000 and 2011 (MAE p = 0.0005; death p = 0.037; Figure). By multivariate analysis, the MAE rate increased at high volume centers compared to low volume centers (p = 0.02). Conclusions: Despite the increasing number of lead extractions performed and a decreasing number of hospitals performing lead extraction, there was an increasing rate of associated adverse events and mortality.
Coordinate Transformation Based Field Tapering Device (2018)

Spatial coordinate transformations can be used in the design of electromagnetic devices with unconventional and exotic behavior. However, their realizations are generally limited by the complex material properties that are required. In this paper, the coordinate transformation technique is employed to successfully design two field tapering devices. 2D continuous models are presented that confirm the desired field tapering functionality for the targeted microwave frequency band. Next, a scheme that utilizes a method of parameter reduction to simplify the complicated tensors produced by the conventional coordinate transformation technique is applied to one of the taper designs. A two-step procedure is introduced to simplify the tensor properties of the material by eliminating non-diagonal components. Furthermore, the resulting permittivity and permeability distributions for the taper device are calculated and presented.
Molecular evolution of the vertebrate immune system. (1994)

An understanding of the evolution of vertebrate immunity is slowly emerging from studies of chordates that share distant&#13;\nancestors with mammals. In higher vertebrates, such as birds and mammals, we know that two receptor systems are operative. B cells use immunoglobulins to bind foreign agents (the functionally defined antigens). T cells use T-cell receptors (TCRs) to respond to antigen in the form of processed peptides bound to cell surface proteins encoded in the major histocompatibility complex (MHC). Thus, for T cells, two receptor molecules are required for recognition of antigen. First, the MHC molecule on the infected cell binds the processed antigenic peptide; second, the TCR binds the MHC molecule-antigenic peptide complex.
High Data-Rate and Long Distance MCF Transmission With 19-Core C+L band Cladding-Pumped EDFA (2019)

We describe a series of optical transmission experiments based around single-mode, multi-core fiber (MCF) amplified with 19-core, C+L band erbium-doped fiber amplifier (EDFA). The cladding-pumped amplifier uses two multi-mode pumps in each of C and L band to provide gain bandwidth over more than 75 nm. For recirculating transmission of PDM-16QAM signals on 345 wavelength carriers between 1530.52 nm and 1605.52 nm, we measure 0.715 Pb/s transmission over a distance of 2009 km (64 recirculations), equivalent to a throughput-distance product of 1.44 exabit/s x km. Next, using PDM-QPSK modulation, we investigate trans-oceanic transmission distances, measuring throughputs of 18.6 Tb/s and 14.5 Tb/s in 2 cores after 255 recirculations, a distance of 8007 km. Further, we evaluate the combined EDFA and fiber crosstalk penalties showing a core and wavelength dependence in agreement with previous MCF crosstalk measurements. These results demonstrate the potential of high core-count EDFAs to combine both high capacity transmission over transoceanic distances with benefits of SDM integration.
