Influence of upper ocean stratification interannual variability on tropical cyclones (2014)

Abstract Climate modes, such as the El Niño Southern Oscillation (ENSO), influence Tropical Cyclones (TCs) interannual activity through their effect on large‐scale atmospheric environment. These climate modes also induce interannual variations of subsurface oceanic stratification, which may also influence TCs. Changes in oceanic stratification indeed modulate the amplitude of TCs‐induced cooling, and hence the negative feedback of air‐sea interactions on the TC intensity. Here we use a dynamical downscaling approach that couples an axisymmetric TC model to a simple ocean model to quantify this interannual oceanic control on TC activity. We perform twin experiments with contrasted oceanic stratifications representative of interannual variability in each TC‐prone region. While subsurface oceanic variations do not significantly affect the number of moderate (Category 3 or less) TCs, they do induce a 30% change of Category 5 TC‐days globally, and a 70% change for TCs exceeding 85 m s −1 . TCs in the western Pacific and the southwestern Indian Ocean are most sensitive to oceanic interannual variability (with a ∼10 m s −1 modulation of the intensity of strongest storms at low latitude), owing to large upper ocean variations in response to ENSO. These results imply that a representation of ocean stratification variability should benefit operational forecasts of intense TCs and the understanding of their climatic variability.

Reducing network latency using subpages in a global memory environment (1996)

New high-speed networks greatly encourage the use of network memory as a cache for virtual memory and file pages, thereby reducing the need for disk access. Because pages are the fundamental transfer and access units in remote memory systems, page size is a key performance factor. Recently, page sizes of modern processors have been increasing in order to provide more TLB coverage and amortize disk access costs. Unfortunately, for high-speed networks, small transfers are needed to provide low latency. This trend in page size is thus at odds with the use of network memory on high-speed networks.This paper studies the use of subpages as a means of reducing transfer size and latency in a remote-memory environment. Using trace-driven simulation, we show how and why subpages reduce latency and improve performance of programs using network memory. Our results show that memory-intensive applications execute up to 1.8 times faster when executing with 1K-byte subpages, when compared to the same applications using full 8K-byte pages in the global memory system. Those same applications using 1K-byte subpages execute up to 4 times faster than they would using the disk for backing store. Using a prototype implementation on the DEC Alpha and AN2 network, we demonstrate how subpages can reduce remote-memory fault time; e.g., our prototype is able to satisfy a fault on a 1K subpage stored in remote memory in 0.5 milliseconds, one third the time of a full page.
Abstract 5207: HIF-1α regulates the Tie2 receptor on Tie2-expressing monocytes in PyMT breast tumors and augments angiogenic function and metastatic potential (2018)

Abstract Tissue oxygenation in the tumor microenvironment serves as a significant parameter in tumor pathophysiology. In fact, normalization of tumor oxygen is associated with inhibition of tumor growth and metastatic capacity. Irregular tumor vessels produced during tumor angiogenesis have low blood perfusion; thus, oxygen transport is decreased in tumors. Tie2-expressing monocytes (TEMs) are a distinct subset of proangiogenic monocytes selectively recruited to tumors in breast cancer patients. Due to the hypoxic nature of the tumor microenvironment, we investigated if oxygen regulates the trafficking of these cells into tumors or if oxygen regulates monocyte differentiation into TEMs once inside the tumor proper. To understand the differentiation of F4/80+/Tie2- cells to Tie2-positivity, we orthotopically implanted PyMT breast tumor cells containing particulate lithium octa-n-butoxy-naphthalocyanine (LiNcBuO) into the mammary fat pads of LysM-Cre control and HIF-1αfl/fl/LysM-Cre mice and evaluated tissue oxygenation by electron paramagnetic resonance (EPR), TEM infiltration, tumor angiogenesis, and metastatic potential. Longitudinal monitoring of physiologic oxygen in tumors using EPR demonstrates the significant role of oxygen-driven TEM regulation in tumor angiogenesis and progression. Citation Format: Kayla J.

Organizational learning model for adaptive collective behaviors in multiple robots (1997)

This paper proposes a novel organizational learning model in which multiple robots acquire their own functions for adaptive collective behaviors through local interactions among their neighbors and form an organizational structure to complete given tasks without global explicit control mechanisms or communication methods. In this paper, we focus on emergent processes in which robots dynamically form an organizational structure by acquiring their own appropriate functions to complete given tasks effectively and also focus on how organizational knowledge supports robots to reform their organizational structure. Through intensive simulations of truss construction by multiple robots, the following experimental results have suggested: (1) robots in our model acquire their own appropriate functions without global explicit control mechanisms or communication methods and form an organizational structure which completes given tasks in less steps than those with a centralized control system, and (2) organizational ...

A prototype Crew Medical Restraint System (CMRS) for Space Station Freedom (1992)

The Crew Medical Restrain System (CMRS) is a prototype system designed and developed for use as a universally deployable medical restraint/workstation on Space Station Freedom (SSF), the Shuttle Transportation System (STS), and the Assured Crew Rescue Vehicle (ACRV) for support of an ill or injured crewmember requiring stabilization and transportation to Earth. The CMRS will support all medical capabilities of the Health Maintenance Facility (HMF) by providing a restraint/interface system for all equipment (advance life support packs, defibrillator, ventilator, portable oxygen supply, IV pump, transport monitor, transport aspirator, and intervenous fluids delivery system) and personnel (patient and crew medical officers). It must be functional within the STS, ACRV, and all SSF habitable volumes. The CMRS will allow for medical capabilities within CPR, ACLS and ATLS standards of care. This must all be accomplished for a worst case transport time scenario of 24 hours from SSF to a definitive medical care facility on Earth. A presentation of the above design prototype with its subsequent one year SSF/HMF and STS/ACRV high fidelity mock-up ground based simulation testing will be given. Also, parabolic flight and underwater Weightless Test Facility evaluations will be demonstrated for various medical contingencies. The final design configuration to date will be discussed with future space program impact considerations.
Enteral administration of soyabean lecithin enhanced lymphatic absorption of triacylglycerol in rats (2003)

As the physiological roles of dietary lecithin have not yet been clearly defined, we examined the effects of lecithin on lipid absorption in male Wistar rats with a mesenteric lymph cannula. Lymphatic absorption was observed after the infusion of 1 ml emulsion containing 100 mg test oil emulsified with sodium taurocholate (10 g/l) in three separate experiments. Test oils (100 mg) were: soyabean oil (triacylglycerol (TG) source, SO) and soyabean oil+lecithin (75 mg soyabean oil+25 mg lecithin, LE) in Expt 1; SO, LE or soyabean oil+lysolecithin (75 mg soyabean oil plus 25 mg lysolecithin, LY) in Expt 2; hydrolysed soyabean oil (HSO) or HSO+lysolecithin (75 mg HSO+25 mg lysolecithin, HLY) in Expt 3. After LE and LY infusions, lymph flow and the lymphatic output of TG was higher than after SO infusion at 0-30 min and 0-90 min respectively (Expts 1 and 2). Lecithin-induced increases in lymph TG output remained constant when HSO was infused (Expt 3). There were no differences in the TG:phospholipid ratio in the lymph after infusion among the groups; nevertheless, the lymphatic output of TG was much higher after infusion with LE than with SO. Fatty acid was released more efficiently from SO than from LE and LY by in vitro digestion with rat bile-pancreatic juice. These present results demonstrate that a TG emulsion containing soyabean lecithin or its hydrolysates promote lymphatic TG output and suggest that the increases in TG absorption do not depend on TG digestion.
Dimension Reduction and Dynamics of a Spiking Neural Network Model for Decision Making under Neuromodulation (2011)

Previous models of neuromodulation in cortical circuits have used either physiologically based networks of spiking neurons or simplified gain adjustments in low-dimensional connectionist models. Here we reduce a high-dimensional spiking neuronal network model, first to a four-population mean-field model and then to a two-population model. This provides a realistic implementation of neuromodulation in low-dimensional decision-making models, speeds up simulations by three orders of magnitude, and allows bifurcation and phase-plane analyses of the reduced models that illuminate neuromodulatory mechanisms. As modulation of excitation-inhibition varies, the network can move from unaroused states, through optimal performance to impulsive states, and eventually lose inhibition-driven winner-take-all behavior: all are clear outcomes of the bifurcation structure. We illustrate the value of reduced models by a study of the speed-accuracy tradeoff in decision making. The ability of such models to recreate neuromodulatory dynamics of the spiking network will accelerate the pace of future experiments linking behavioral data to cellular neurophysiology.

Constructing smooth finite element models of patient specific ankle foot orthoses (2010)

In clinical practice, ankle foot orthoses or AFOs are frequently prescribed to help patients to cope with walking difficulties caused by neuromuscular problems in the lower leg region. Even though the mechanics of the AFO play an important role in the gait kinematics, the effect of different design parameters on the final mechanical response of the orthotic is not fully understood and little research on the topic has been published 1-4 . As such, it would be preferable to have a better understanding of the influence that different design parameters have on the mechanical response of AFOs. Such a knowledge would be beneficial to the design and construction of patient specific AFOs, as the labour intensive production yields orthotics that are largely dependent on both the skill and experience of the technician. This study therefore focuses on the development of a fast and user friendly methodology for constructing finite element models of patient specific polypropylene AFOs that can incorporate different design adaptations, using the open-source pyFormex 5 platform.
A molecular beam study of the reaction of WF6 on Si(100) (1988)

We have studied the reduction of WF6 on Si(100) for the selective deposition of tungsten on silicon from 300°C to 700°C. We simulated the process by impinging a pulsed beam of WF6 on Si(100) surfaces and used time‐resolved mass spectrometry to monitor the evolution of the reaction products. While SiF4 is the major reaction product below 400°C, SiF2 becomes the dominant species above 500°C with a gradual transition as the temperature is raised to 500°C. Both SiF2 and SiF4 have a fast and a slow component. It is very likely that the fast component, which is dominant at high temperatures, may be produced by the immediate reaction of WF6 with Si as the molecule strikes the Si(100) surface. The slow component, which can have time scales in the order of tens of seconds, is likely related to the regrouping of fluorine atoms on the silicon surface to form the volatile products. We also found that Si atoms, which diffuse through the W overlayer, can sustain the WF6 reduction reaction. The production of SiF2 and SiF4 from such a Si layer on W is qualitatively similar to that from the bare Si surface.
Measuring and Removing Dissolved Metals from Stormwater in Highly Urbanized Areas (2014)

This report presents prototype best management practices for the removal of dissolved metals in stormwater runoff. Three conceptual configurations are presented in detail: two vault system configurations for urban and rural settings, and an inlet scupper with media for bridge deck drainage systems. The report also includes standard protocols to accurately measure the levels of dissolved metals in stormwater. Practical guidance on the use of these protocols is provided in an appendix to the final report. The report is accompanied by an Excel spreadsheet on CD (CRP-CD-147) designed to assist in sizing the filter bed in the vaults and the bridge deck inlet scupper. The report is suitable for immediate application by transportation practitioners in planning, design, and construction, particularly in areas where receiving waters are most susceptible to the impacts of dissolved metals.
Psl: a novel Spm‐like transposable element from Petunia hybrida (1998)

The identification of a spontaneous mutable Hf1 allele in Petunia hybrida provided an opportunity to isolate and characterize a novel transposable element. This 9.9 kb element has features in common with members of the Spm family, such as homologous terminal inverted repeats and a 3 bp target site direct duplication within the Hf1 gene. The element is named Petunia Spm-like (Psl). The footprints left by excising elements have been isolated from several germinal revertants and sequence analysis shows similarities to those left by other Spm family members. Southern analysis shows that the transposon is present at low copy number in the genome of different inbred lines and species of Petunia. The germinal excision frequency of Psl was 21-33% in outcross populations. The element appears to be very mobile somatically in the inbred line V26, with 38% of plants from an inbred population showing new Psl-hybridizing bands by Southern analysis. The high somatic and germinal excision frequency demonstrated by Psl suggests that this element may have utility for gene tagging in petunia.
Glaucoma: early detection and therapy for prevention of vision loss. (1995)

Glaucoma is the second most common cause of permanent blindness in the United States and the most common cause of blindness among blacks. It is characterized by optic atrophy and vision loss, resulting from intraocular pressure that is too high to allow normal function of the optic nerve. Examination of the optic nerve and assessment of individual risk factors aids in the identification of patients who are at risk for glaucoma. Although glaucoma is a chronic disease, ocular complications can be prevented and sight may be preserved if the disease is detected early. A combination of antiglaucoma medications, laser treatment and filtration surgery is used to maintain intraocular pressure at a level sufficient to halt progression of optic nerve injury and prevent further vision loss.
Desmoplastic fibroblastoma: a case presenting as a protruding nodule in the dermis (2008)

Desmoplastic fibroblastoma is a rare, benign, soft tissue tumor. We describe a case of superficial desmoplastic fibroblastoma presenting as a protruding nodule. A 41-year-old woman presented with a painless, firm, elevated nodule with ulceration on her left thigh. Histological examination from total excision showed a well-circumscribed tumor in the dermis, which comprised of spindle, oval and stellate cells arranged in a haphazard fashion, accompanied by abundant collagenous stroma and inconspicuous vasculature. Immunohistochemically, the tumor cells were positive for vimentin, and focally positive for alpha-smooth muscle actin and muscle-specific actin, but negative for CD34, S-100 protein, desmin and beta-catenin. We diagnosed this case as desmoplastic fibroblastoma arising in the dermis and superficial subcutaneous tissue.
Mitigation of mode partition noise in quantum-dash Fabry-Perot mode-locked lasers using Manchester encoding and balanced detection (2017)

We propose the use of Manchester encoding in conjunction with balanced detection to overcome the mode partition noise (MPN) limit of quantum-dash Fabry-Perot mode-locked lasers (QD-MLLs) used as multi-wavelength sources in short-reach applications. The proposed approach is demonstrated for a 10-mode laser, each carrying a 10-Gb/s signal. We show that bit-error-rate floors as high as 10<sup>-4</sup> when traditional non-return-to-zero (NRZ) modulation is employed with a single-ended detection scheme can be pushed below 10<sup>-9</sup> thanks to the introduction of Manchester encoding together with balanced detection. The benefit of the scheme could be attributed to the spectral shift of the Manchester spectrum, resulting in a smaller overlap with the high-relative intensity noise (RIN) region present at low frequencies, and the use of balanced detection. We clarify the origin of the performance improvement through comparisons of single-ended and balanced detection and the use of a RIN emulation technique. We unambiguously show that the use of balanced detection plays the leading role in MPN mitigation enabled by Manchester modulation.
