GEO Atmospheric Sounder Technology Project (2005)

Microwave and (sub) millimetre wave atmospheric sounders provide information on the distribution of radiation emitted by the atmosphere from which vertical profiles of temperature and humidity through the atmosphere may be obtained. Current generation of sounders are embarked on-board low Earth orbit (LEO) satellites for providing primarily meteorological data for numerical weather forecasting, and on the second level global observations for climate monitoring. Geostationary observations, unlike those from LEO satellites, have the key potential advantage to provide continuous coverage of the same region, which is essential for now casting. A preliminary review of potential Geostationary Earth Orbit (GEO) missions, based of geophysical parameters, gave consideration to three main application areas for GEO sounding: numerical weather prediction (NTASK), climatology and now casting. In contrast to LEO microwave sounders in operation today, the proposed straw man GEO instrument uses many more channels that range in frequency from 89 GHz through to 874 GHz. Due to the large aperture size required to achieve a reasonable horizontal resolution, its use has so far been restricted to the case of Low Earth Orbit (LEO) satellites. The earth seen in different frequency bands, and one receiver element for the 53 GHz band. The overall objective of this activity is to develop and demonstrate enabling instrument concepts to achieve accurate observation at significant spatial resolution with microwave and (sub)millimetre wave sensors from Geosynchronous Earth Orbit (GEO). This will entail the development and demonstration of the required innovative technologies as part of a demonstrator. Omnisys has lead an ESA study to select candidate breakthrough concepts to meet the requirements. The selected concept will be demonstrated and bread boarding of the critical technologies be performed during the second part of the study. The overall instrument concept will be presented as well as key technology development areas. In terms of performance, the specification is: 30 km resolution (400x400 map), covering the bands 53, 90, 119, 160, 183, 340, 380 GHz, and an update rate of 30 minutes. This will be accomplished with an instrument in the 200 kg / 300 W class, using 500+ (sub)millimeter receivers mounted on booms. The deployed booms stretch over an 8 meter diameter. 16th International Symposium on Space Terahertz Technology

Comparison of Locus Coeruleus Pathology with Nigral and Forebrain Pathology in Parkinson's Disease (2021)

These findings show that in the same Parkinson's disease cases cell loss in these neurotransmitter systems does not follow a strict caudal to rostral trajectory and suggests symptom onset may relate to substantial pathology in the noradrenergic A6 locus coeruleus neurons in people with reduced dopamine-producing A9 substantia nigra neurons. © 2021 International Parkinson and Movement Disorder Society.
Prioritizing Change-Impact Analysis via Semantic Program-Dependence Quantification (2015)

Software is constantly changing. To ensure the quality of this process, when preparing to change a program, developers must first identify the main consequences and risks of modifying the program locations they intend to change. This activity is called change-impact analysis. However, existing impact analysis suffers from two major problems: coarse granularity and large size of the resulting impact sets. Finer-grained analyses such as slicing give more detailed impact sets which, however, are also even larger in size. While various impact-set reduction approaches have been proposed at different levels of granularity, the challenge persists as very-large impact sets are still produced, impeding the adoption of impact analysis due to the great costs of inspecting those impact sets. To address these challenges, we present a novel dynamic-analysis technique called SensA which combines sensitivity analysis and execution differencing. SensA not only provides fine-grained (statement-level) impact sets but also prioritizes potential impacts via semantic-dependence quantification for program slices. We evaluated the benefits of impact prioritization using SensA with respect to static and dynamic forward slicing via an extensive empirical study of open-source Java applications and three case studies. Our results show that SensA can offer much better cost-effectiveness than slicing in assisting developers with impact inspection and fault cause-effect understanding.
Transmission of intrathoracic pressure to the intracranial space during cardiopulmonary resuscitation in dogs. (1985)

Elevation of intrathoracic pressure during cardiopulmonary resuscitation generates carotid pressure and flow, but also increases intracranial pressure. This increase in intracranial pressure may limit cerebral blood flow. Therefore, we performed studies designed to quantify the extent of this transmission and to identify the mechanism of transmission of intrathoracic pressure to the intracranial space during cardiopulmonary resuscitation in dogs. Intracranial pressure increased during the chest compression phase of all modes of cardiopulmonary resuscitation tested. During simultaneous compression-ventilation cardiopulmonary resuscitation, change in intracranial pressure (mm Hg) = 0.33 change in intrathoracic pressure (mm Hg) + 2.02 (r = 0.86) and was not significantly different from the relationship observed during conventional cardiopulmonary resuscitation. The magnitude of transmission of intrathoracic pressure to the intracranial space was increased by binding the abdomen and by raising the baseline intracranial pressure. No single route accounted for transmission of intrathoracic pressure to the intracranial space during cardiopulmonary resuscitation. Intracranial pressure fluctuations were unrelated to either carotid arterial or jugular venous pressure, and were found instead to be the result of pressure transmission by blood in non-valved veins and by cerebrospinal fluid. This was determined by three maneuvers. First, obstruction of cerebrospinal fluid flow by ligation of the cervical spinal cord reduced intracranial pressure (P less than 0.001) and made the change in intracranial pressure equivalent to pressure changes at the confluence of the intracranial venous sinuses, without affecting pressure changes at the confluence of the intracranial venous sinuses. Second, ligation of the cervical spinal cord and one of the two longitudinal vertebral veins adjacent to the cervical cord reduced the pressure changes in the intracranial space and at the confluence of the intracranial venous sinuses to about 60% of the levels observed when the cervical cord alone was ligated. Thus, the non-valved longitudinal vertebral veins appear to be the vascular channels of critical importance to pressure transmission. Finally, pressure changes in the thoracic cerebrospinal fluid were increased (P less than 0.05) by cord ligation, even after exsanguination minimized pressure transmission via blood-filled channels, indicating direct transmission of intrathoracic pressure through intervertebral foramina to the cerebrospinal fluid.(ABSTRACT TRUNCATED AT 400 WORDS)

FM-04 A Sheet-Handling Mechanism Using a Tape and Drum (2003)

A sheet-handling mechanism that can take in and discharge various-sized sheets has been developed. The mechanism has a simple structure consisting of a drum, a reel, and a tape between them. It takes in sheets by winding the tape and the sheets around the drum together, and it discharges sheets by rewinding the tape. A sheet-handing test was performed under various feed conditions and showed that sheet-handling mechanism can handle various-sized sheets.
Neural-network-based Path Planning Optimization (2018)

In this paper some Unmanned Aerial Vehicles are equipped with a fixed camera to conduct surveillance operations, the route planning method are presented using neural network method. The simulation results are presented to demonstrate the performance and computational efficiency of the method. As neutral network approximation does not require analytic derivatives, speed could be further enhanced, it could be quite useful for real -time optimization control.
Rapid analysis of foodborne pathogens by surface-enhanced Raman spectroscopy (2012)

Foodborne diseases resulting from Campylobacter, Escherichia, Listeria, Salmonella, Shigella and Vibrio species affect as many as 76 million persons in the United States each year, resulting in 325,000 hospitalizations and 5,000 deaths. The challenge to preventing distribution and consumption of contaminated foods lies in the fact that just a few bacterial cells can rapidly multiply to millions, reaching infectious doses within a few days. Unfortunately, current methods used to detect these few cells rely on lengthy growth enrichment steps that take a similar amount of time (1 to 4 days). Consequently, there is a critical need for an analyzer that can rapidly extract and detect foodborne pathogens in 1-2 hours (not days), at 100 colony forming units per gram of food, and with a specificity that differentiates from indigenous microflora, so that false alarms are eliminated. In an effort to meet this need, we have been developing a sample system that extracts such pathogens from food, selectively binds these pathogens, and produces surface-enhanced Raman spectra (SERS). Here we present preliminary SERS measurements of Listeria and Salmonella.
Multiple Purpose Simulator Using a Natural Porcine Mitral Valve (2004)

An in vitro pulsatile simulator with a porcine mitral valve was developed in order to simulate physiologic and diseased mitral valve conditions. Evaluation of these conditions was conducted from a hydrodynamic and annulus behavior point of view. We found it possible to simulate mild "mitral valve prolapse" and to obtain quantitative data related to the condition. The diseased condition produced a 40% greater regurgitant volume than that observed under the normal condition (p < 0.0001). Regarding the leakage volume, the diseased condition exhibited about 2.6 times more leakage than the normal condition. The mitral valve simulator proposed in this study is considered fairly stable with respect to both hemodynamics and the behavior of the annulus, and it is an adequate simulator for modeling various types of normal and diseased mitral valve conditions.
Interferometric analysis of a lithium niobate with engineering reversed domains (2003)

We report an interferometric analysis of 0.5mm thick lithium niobate crystal sample by making use of a reflective grating interferometer and a digital holographic technique. The lithium niobate wafer was subjected to electric field poling in order to obtain two antiparallel ferroelectric domains. The crystal was then mounted into one arm of the interferometer in order to study the phase map and consequently to evaluate the effects of domain reversion at the boundary. Engineering of periodically reversed domains in LN is extensively used for quasi-phase-matching applications while the ferroelectric structure investigated here is suitable for producing electro-optically controlled deflector or switch devices via total internal reflection at the domain interface. The above mentioned applications require deep knowledge of how the domain reversal process affects the optical properties of the ferroelectric crystals.
A Benchmark of Globally-Optimal Anonymization Methods for Biomedical Data (2014)

Collaboration and data sharing have become core elements of biomedical research. At the same time, there is a growing understanding of privacy threats related to data sharing, especially when sensitive data from distributed sources become available for linkage. Statistical disclosure control comprises well-known data anonymization techniques that allow the protection of data by introducing fuzziness. To protect datasets from different types of threats, different privacy criteria are commonly implemented. Data anonymization is an important measure, but it is computationally complex, and it can significantly reduce the expressiveness of data. To attenuate these problems, a number of algorithms has been proposed, which aim at increasing data quality or improving efficiency. Previous evaluations of such algorithms lack a systematic approach, as they focus on specific algorithms, specific privacy criteria, and specific runtime environments. Therefore, it is difficult for decision makers to decide which algorithm is best suited for their requirements. As a first step towards a comprehensive and systematic evaluation of anonymity algorithms, we report on our ongoing efforts for providing an open source benchmark. In this contribution, we focus on optimal algorithms utilizing global recoding with full-domain generalization. We present a systematic evaluation of domain-specific algorithms and generic search methods for a broad set of privacy criteria, including k-anonymity, l-diversity, t-closeness and d-presence, and their use in multiple real-world datasets. Our results show that there is no single solution fitting all needs, and that generic search methods can outperform highly specialized algorithms.
Targeting Cyclin-Dependent Kinases in Synovial Sarcoma: Palbociclib as a Potential Treatment for Synovial Sarcoma Patients (2016)

In this series nuclear phospho-Rb and nuclear β-catenin expression were negative prognostic factors. In vitro data suggest that palbociclib may be a potential treatment for a subset of synovial sarcoma patients. Whether this effect can be enhanced by combination treatment deserves further preclinical investigations.
Low cost single-phase semi-Z-source inverter (2011)

This paper presents several single-phase non-isolated semi-Z-source inverters for small distributed power generator in grid-connected applications with low cost and doubly grounded features. These semi-Z-source inverters employ the Z-source/quasi-Z-source network and only two active switches to achieve the same output voltage as the traditional voltage-fed full-bridge inverter. The two active switches of the semi-Z-source inverter are controlled complementarily. Different from the traditional single-phase Z-source/quasi-Z-source inverter, shoot-through zero state is not applicable for the semi-Z-source inverter. The input dc source and the output ac voltage of the semi-Z-source inverter share the same ground, thus leading to less leakage ground current advantages over other non-doubly grounded inverters, such as voltage fed full-bridge inverter. This is a preferred feature for non-isolated grid-connected inverters especially in photovoltaic application. A revised non-linear sinusoid pulse width modulation method for semi-Z-source inverter is also proposed. By using this method, desired duty cycle can be generated to output the sinusoidal voltage. Other dc-dc converters with similar voltage gain curve, which can also be used as a single-phase inverter are also discussed and summarized. A single-phase semi-Z-source inverter prototype is built, experimental results are provided to verify and demonstrate the special features of the proposed circuit.
A novel strain enhanced CMOS architecture using selectively deposited high tensile and high compressive silicon nitride films (2005)

A novel CMOS architecture utilizing tensile/compressive silicon nitride capping layers to induce tensile/compressive strain in NMOSFET/PMOSFET channel regions was developed. NMOSFET device delivers 1.05mA//spl mu/m on-current for 70nA//spl mu/m off-current at IV drain voltage. PMOS device exhibits peak 66% increase of linear drain current and 55% increase of saturation current. It was shown that drain current improvements both for N- and PMOSFETs strongly correlate with channel doping levels. Therefore, advanced methods of shallow and low resistance junction formation are required for maintaining low channel doping concentration and efficiently utilizing channel strain at sub-40nm gate length.
Role of tryptophan degradation in respiratory burst-independent antimicrobial activity of gamma interferon-stimulated human macrophages (1989)

To determine whether extracellular tryptophan degradation represents an oxygen-independent antimicrobial mechanism, we examined the effect of exogenous tryptophan on the intracellular antimicrobial activity of gamma interferon (IFN-gamma)-stimulated human macrophages. IFN-gamma readily induced normal monocyte-derived macrophages (MDM) to express indoleamine 2,3-dioxygenase (IDO) activity and stimulated MDM, alveolar macrophages, and oxidatively deficient chronic granulomatous disease MDM to degrade tryptophan. All IFN-gamma-activated, tryptophan-degrading macrophages killed or inhibited Toxoplasma gondii, Chlamydia psittaci, and Leishmania donovani. Although exogenous tryptophan partially reversed this activity, the increases in intracellular replication were variable for normal MDM (T. gondii [5-fold], C. psittaci [3-fold], L. donovani [2-fold]), chronic granulomatous disease MDM (T. gondii [2.5-fold], C. psittaci [5-fold]), and alveolar macrophages (T. gondii [1.5-fold], C. psittaci [1.5-fold]). In addition, IFN-alpha and IFN-beta also stimulated normal MDM to express IDO and degrade tryptophan but failed to induce antimicrobial activity, and IFN-gamma-treated mouse macrophages showed neither IDO activity nor tryptophan degradation but killed T. gondii and L. donovani. These results suggest that while tryptophan depletion contributes to the oxygen-independent antimicrobial effects of the activated human macrophage, in certain cytokine-stimulated cells, tryptophan degradation may be neither sufficient nor required for antimicrobial activity.
Time of Day-Dependent Effects of Thyroliberin and Thyrotropin on Thymocyte Proliferation in Rats (2000)

Our earlier studies have shown that thyroliberin (TRH) as well as thyrotropin (TSH) enhanced thymus cell proliferation. The aim of the present study was to investigate whether the effects of TRH and TSH on thymocyte proliferation depend on time of day. A single subcutaneous injection of TRH (25 microgram/animal) or TSH (3 IU/animal) was made at 9:00 h (1 h after light onset) or at 18:00 h (10 h after light onset) in 3-month-old male Wistar rats. The animals were killed 24 h later. The proliferation of thymocytes was assessed by incorporation of bromodeoxyuridine into cell nuclei. Thymocyte proliferation was significantly increased by TSH administration at 9:00 h, whereas treatment given at 18:00 h was ineffective. TRH enhanced the proliferation when injected at 9:00 h, but had an inhibitory effect when administered at 18:00 h. These data indicate that the effects of TRH and TSH on thymocyte proliferation are dependent on time of day.

Bright lights of Loughborough (1975)

Although many meetings are held regularly to discuss laser technology and applications, the scientists and engineers working on the apparently mundane aspects of lamps rarely get together as a specialized group. In fact there is much to discuss, since after considerable research and development, several important new light sources have emerged in recent years.
How Will the Patient Protection and Affordable Care Act Affect Liability Insurance Costs? (2014)

The Patient Protection and Affordable Care Act (ACA) will greatly expand private coverage and Medicaid while making major changes to payment rates and the health care delivery system. These changes will affect traditional health insurers, individuals, and government payers. In addition, a considerable amount of health care is paid for directly by or is indirectly paid for via legal settlements after the care occurs, by liability insurers. This study identifies potential mechanisms through which the ACA might affect claim costs for several major types of liability coverage, especially auto insurance, workers' compensation coverage, and medical malpractice. The authors discuss the conceptual basis for each mechanism, review existing scholarly evidence regarding its importance, and, where possible, develop rough estimates of the size and direction of expected impacts as of 2016. They examine how each mechanism might operate across different liability lines and discuss how variation across states in legal rules, demographics, and other factors might moderate each mechanism's operation. Overall, expected short-term effects of the ACA appear likely to be small relative to aggregate liability insurer payouts in the markets in question. However, under reasonable assumptions, some mechanisms can generate potential cost changes as high as 5 percent or more in particular states and insurance lines. The authors also discuss longer-run changes that could be fostered by the ACA that might exert more significant effects on insurance claim costs, including shifts in tort law, changes in physician supply, new pricing approaches under the accountable care organization model, and changes in population health.
In vivodeep-tissue microscopy with UCNP/Janus-dendrimers as imaging probes: resolution at depth and feasibility of ratiometric sensing (2020)

Lanthanide-based upconverting nanoparticles (UCNPs) are known for their remarkable ability to convert near-infrared energy into higher energy light, offering an attractive platform for construction of biological imaging probes. Here we focus on in vivo high-resolution microscopy - an application for which the opportunity to carry out excitation at low photon fluxes in non-linear regime makes UCNPs stand out among all multiphoton probes. To create biocompatible nanoparticles we employed Janus-type dendrimers as surface ligands, featuring multiple carboxylates on one 'face' of the molecule, polyethylene glycol (PEG) residues on another and Eriochrome Cyanine R dye as the core. The UCNP/Janus-dendrimers showed outstanding performance as vascular markers, allowing for depth-resolved mapping of individual capillaries in the mouse brain down to a remarkable depth of ∼1000 μm under continuous wave (CW) excitation with powers not exceeding 20 mW. Using a posteriori deconvolution, high-resolution images could be obtained even at high scanning speeds in spite of the blurring caused by the long luminescence lifetimes of the lanthanide ions. Secondly, the new UCNP/dendrimers allowed us to evaluate the feasibility of quantitative analyte imaging in vivo using a popular ratiometric UCNP-to-ligand excitation energy transfer (EET) scheme. Our results show that the ratio of UCNP emission bands, which for quantitative sensing should respond selectively to the analyte of interest, is also strongly affected by optical heterogeneities of the medium. On the other hand, the luminescence decay times of UCNPs, which are independent of the medium properties, are modulated via EET only insignificantly. As such, quantitative analyte sensing in biological tissues with UCNP-based probes still remains a challenge.
