Trajectory estimation improvement based on time-series constraint of GPS Doppler and INS in urban areas (2012)

With the development of various driver assistance systems using vehicle position, improvement of positioning accuracy is desired. GPS, widely used as a positioning system, can provide accuracy of a few meters in suburban areas. However, in urban areas, this accuracy can be degraded to ten meters or more because of the reflection and blocking of GPS signals by tall buildings. In order to maintain accurate positioning in such an environment, it is important to develop a method of trajectory estimation which is robust against the surrounding buildings. In this paper, the heading estimation which is the most influential factor in trajectory accuracy is improved by tight coupling of time-series GPS-Doppler and INS. As a result, the accuracy of trajectory estimation is improved in urban areas.
Studies of synthesis and cationic photopolymerization of three isomeric monoterpene diepoxides (1995)

Abstract The monoterpene diepoxides isoascaridole ( III ), γ‐terpinene diepoxide ( V ), and limonene diepoxide ( VIII ) were prepared from the corresponding hydrocarbons and their reactivity in photoinitiated cationic polymerization examined. Both V and VIII underwent facile and rapid polymerization to give crosslinked polyethers III , but although highly reactive, did not undergo crosslinking polymerization. With the aid of model compounds it was determined that the rearrangement of one of the epoxy groups of III takes place in the presence of photogenerated acid to give an epoxy ketone ( XIII ) as the primary product. XIII undergoes very sluggish polymerization. © 1995 John Wiley & Sons, Inc.
Distributed rate control algorithm for VANETs (DRCV) (2009)

This paper presents Distributed Rate Control for VANETs (DRCV), a distributed light-weight congestion control algorithm tailored for safety messages. DRCV monitors and estimates channel load and controls the packet rate of outgoing periodic packets. A new approach called Fast Drop is adopted to promptly drop the rate of periodic packets when event-driven safety packets are detected. Simulations show the effectiveness of DRCV in increasing packet reception probabilities and achieving efficient channel usage.
Oil recovery from a Utah tar sand deposit by in situ combustion (1978)

The U. S. tar sand resource consists of an estimated 30 billion barrels (4.7Gm) of oil. Most of this resource is in six large deposits in Utah. Through research and development to prove tar sand oil recovery methods, the Department of Energy is attempting to stimulate commercialization of this resource. Two in situ combustion field experiments have been conducted in Utah&apos;s Northwest Asphalt Ridge deposit. The second of these experiments, described in detail, was completed in early 1978 and consisted of a reverse combustion preparatory phase followed by a forward combustion production phase. Oil recovery exceeding 20 percent of the oil-in-place from a 40 ft by 120 ft (12m by 36m) nine-well line pattern provides encouragement for larger scale technical and economic demonstrations. This report includes the following in detail: the design of the oil production process and its related air injection and production facilities; ignition of the process; conduct of the process (for 183 days); effluent moni-toring; data acquisition (including use of an on-site minicomputer); data analysis; and resultant conclusions.
Membrane vesicles, current state-of-the-art: emerging role of extracellular vesicles (2011)

Release of membrane vesicles, a process conserved in both prokaryotes and eukaryotes, represents an evolutionary link, and suggests essential functions of a dynamic extracellular vesicular compartment (including exosomes, microparticles or microvesicles and apoptotic bodies). Compelling evidence supports the significance of this compartment in a broad range of physiological and pathological processes. However, classification of membrane vesicles, protocols of their isolation and detection, molecular details of vesicular release, clearance and biological functions are still under intense investigation. Here, we give a comprehensive overview of extracellular vesicles. After discussing the technical pitfalls and potential artifacts of the rapidly emerging field, we compare results from meta-analyses of published proteomic studies on membrane vesicles. We also summarize clinical implications of membrane vesicles. Lessons from this compartment challenge current paradigms concerning the mechanisms of intercellular communication and immune regulation. Furthermore, its clinical implementation may open new perspectives in translational medicine both in diagnostics and therapy.

ADAM10 Mediates Vascular Injury Induced by Staphylococcus aureus α-Hemolysin (2012)

Staphylococcus aureus is a leading cause of bacteremia and sepsis. The interaction of S. aureus with the endothelium is central to bloodstream infection pathophysiology yet remains ill-understood. We show herein that staphylococcal α-hemolysin, a pore-forming cytotoxin, is required for full virulence in a murine sepsis model. The α-hemolysin binding to its receptor A-disintegrin and metalloprotease 10 (ADAM10) upregulates the receptor's metalloprotease activity on endothelial cells, causing vascular endothelial-cadherin cleavage and concomitant loss of endothelial barrier function. These cellular injuries and sepsis severity can be mitigated by ADAM10 inhibition. This study therefore provides mechanistic insight into toxin-mediated endothelial injury and suggests new therapeutic approaches for staphylococcal sepsis.
Enhancing the Anion-Transport Selectivity of Multilayer Polyelectrolyte Membranes by Templating with Cu<sup>2+</sup> (2002)

Alternating deposition of oppositely charged polyelectrolytes on porous supports is an attractive way to synthesize selective, ultrathin ion-separation membranes. This study reports the use of Cu2+ as a template in poly(acrylic acid) (PAA)/poly(allylamine hydrochloride) (PAH) membranes to control fixed charge density and hence enhance anion-transport selectivity. Alternating deposition of PAA partially complexed with Cu2+ and PAH on porous alumina supports followed by removal of Cu2+ and deprotonation results in fixed −COO- sites in these films. Cu2+-templated PAA/PAH membranes show a 4-fold increase in Cl-/SO42- transport selectivity compared to pure PAA/PAH membranes deposited under similar conditions. Cross-linking of these templated membranes further increases Cl-/SO42- selectivity by an order of magnitude to a value of 610. Changing the top layer of cross-linked, Cu2+-templated membranes from negatively charged PAA to positively charged PAH decreases Cl-/SO42- selectivity 10-fold, indicating that Donnan repulsion from a negatively charged surface is a major factor behind selectivity. Modeling studies suggest that selectivity is due to both Donnan exclusion and diffusivity differences among ions.
A note on the repeatability of parameters of the lactation curve in cattle (1970)

SUMMARY A study of 1567 lactations of 336 Friesian cows in 10 herds has been undertaken to establish to what extent the shape of the lactation curve varies between parities, cows and herds, and to assess the importance of variations in seasonality from year to year, with particular reference to herd production forecasts. In general, cows calving the same parity at the samé time of year showed similar curves, modified only by total yield and abnormal seasonality of production. Production forecasts based on month/parity subclasses are therefore adequate, provided due account is taken of extréme variations in weather conditions or forage growth.
The Ama1-Directed Anaphase-Promoting Complex Regulates the Smk1 Mitogen-Activated Protein Kinase During Meiosis in Yeast (2005)

Smk1 is a meiosis-specific MAPK homolog in Saccharomyces cerevisiae that regulates the postmeiotic program of spore formation. Similar to other MAPKs, it is activated via phosphorylation of the T-X-Y motif in its regulatory loop, but the signals controlling Smk1 activation have not been defined. Here we show that Ama1, a meiosis-specific activator of the anaphase-promoting complex/cyclosome (APC/C), promotes Smk1 activation during meiosis. A weakened allele of CDC28 suppresses the sporulation defect of an ama1 null strain and increases the activation state of Smk1. The function of Ama1 in regulating Smk1 is independent of the FEAR network, which promotes exit from mitosis and exit from meiosis I through the Cdc14 phosphatase. The data indicate that Cdc28 and Ama1 function in a pathway to trigger Smk1-dependent steps in spore morphogenesis. We propose that this novel mechanism for controlling MAPK activation plays a role in coupling the completion of meiosis II to gamete formation.
Me‐bipam for Enantioselective Ruthenium(II)‐Catalyzed Arylation of Aldehydes with Arylboronic Acids (2009)

Ligand design by-pam: A ruthenium-catalyzed asymmetric arylation of aldehydes with arylboronic acids has been developed, giving chiral diarylmethanols in good yields. The use of a chiral bidentate phosphoramidite ligand ((R,R)-Me-bipam) led to excellent enantioselectivities.
SPAD imagers for super resolution microscopy (2018)

The aim of this research is to explore the potential advantages of SPAD imagers used in microscopy. An ideal microscopy detector requires high sensitivity (high quantum efficiency QE or photon detection probability PDP), photon counting operation, low noise (dark current or dark count rate), timing resolution in the order of 100 ps, frame rate higher than 10 fps, a large enough pixel resolution and wavelength resolvability.
A Generalisation, a Simplification and some Applications of Paillier’s Probabilistic Public-Key System (2000)

We propose a generalisation of Paillier's probabilistic public<br />key system, in which the expansion factor is reduced and which allows to adjust the block length of the scheme even after the public key has been fixed, without losing the homomorphic property. We show that<br />the generalisation is as secure as Paillier's original system.<br />We construct a threshold variant of the generalised scheme as well as zero-knowledge protocols to show that a given ciphertext encrypts one of a set of given plaintexts, and protocols to verify multiplicative relations on plaintexts. We then show how these building blocks can be used for applying the<br />scheme to efficient electronic voting. This reduces dramatically the work needed to compute the final result of an election, compared to the previously best known schemes. We show how the basic scheme for a yes/no vote can be easily adapted to casting a vote for up to t out of L candidates. The same basic building blocks can also be adapted to provide receipt-free elections, under appropriate physical assumptions. The scheme for 1 out of L elections can be optimised such that for a certain<br />range of parameter values, a ballot has size only O(log L) bits.
Salamanca Hiddle Is Alive and Well: Developing a Palette for Poetry (1997)

Describes how one eighth-grade teacher, disturbed by students’ ignorance of the variety of poetry available to them, developed a poetry anthology assignment, in which students immersed themselves in poetry for three weeks, each one choosing and creating a poetry anthology comprised of 20 poems. Notes students’ enthusiasm for the project and pride in its results.
Chromatographic separation of<i>cis</i> and<i>trans</i> fatty esters by argentation with a macroreticular exchange resin (1964)

Abstract Methyl oleate and methyl elaidate, as well as other monoene cis and trans isomers of fatty esters, can be separated quickly and conveniently by a preparative chromatographic procedure in which a silver‐saturated ion‐exchange resin is used. Separations are based on differences in stabilites of the silver‐olefin complexes. Recoveries of better than 95% were made, and pure trans and cis monoene fractions were collected. This method can be used to separate saturates from cis and trans monoenes. The cis,trans,cis,cis , and trans,trans ‐9‐12‐octadecadienoates were separated. While cis,trans and trans,trans dienes were cluted separately, the cis,cis diene isomer remained on the column.
Morbidity and Mortality of Renal Dialysis: An NIH Consensus Conference Statement (1994)

The National Institutes of Health Consensus Development Conference on Morbidity and Mortality of Dialysis brought together experts in general medicine, nephrology, pediatrics, biostatistics, and nutrition, as well as a representative of the public, to address the following questions: 1) How does early medical intervention in predialysis patients influence morbidity/mortality? 2) What is the relationship between delivered dialysis dose and morbidity/mortality? 3) Can comorbid conditions be altered by nondialytic interventions to improve morbidity/mortality in dialysis patients? 4) How can dialysis-related complications be reduced? and 5) What are the future directions for research in dialysis? After one and a half days of presentations by experts and discussion by the audience, a consensus panel weighed the evidence and prepared their consensus statement. Among their findings, the consensus panel concluded the following: 1) During the period before dialysis therapy begins, patients, including children, should be referred to a renal team to reduce the morbidity and mortality incurred during this period and during subsequent dialysis therapy; 2) the social and psychological welfare and the quality of life of the patient receiving dialysis are favorably influenced by the early and continued involvement of a multidisciplinary renal team; 3) to avoid a catastrophic onset of dialysis, attempts should be made to institute intervention before dialysis therapy begins and to appropriately initiate dialysis access; 4) quantitative methods now available to objectively evaluate the relation between the delivered dose of dialysis and patient morbidity and mortality suggest that the dose of hemodialysis and peritoneal dialysis has been suboptimal for many patients in the United States; 5) factors contributing to the underdialysis of some patients include problems with vascular and peritoneal access, nonadherence to dialysis prescription, and underprescription of the dialysis dose; 6) cardiovascular mortality accounts for approximately 50% of deaths in patients receiving dialysis, and relative risk factors such as hypertension, smoking, and chronic anemia should be treated as soon as possible after the diagnosis of chronic renal failure; 7) early detection and treatment of malnutrition contribute to the improved survival of patients receiving dialysis; and 8) until randomized, controlled trials have been completed, a delivered hemodialysis dose at least equal to a measured fractional urea clearance Kdr t/V value of 1.2 (single pool) and a delivered peritoneal dialysis dose at least equal to a measured Kpr t/V value of 1.7 (weekly) are recommended.
The Power of Positive Mentors: Variables Associated with Women's Interest in Social Work Administration (1988)

Abstract Some of the strategies for overcoming obstacles to gender parity in organizations include consciousness-raising, mentoring, informal support, training, and role modeling. The present study explored whether there was evidence to support the use of these strategies based upon the past experiences of female graduate social work students. Experiences with mentors and consciousness-raising were the only two variables found to be predictors of interest in administration among these students. Even though these students expressed a preference for the masculine stereotype in their descriptions of the good administrator, this variable was not found to be a predictor of interest in administration.
Polynomial neural networks for airborne applications (2003)

The authors have attempted to develop a polynomial neural network which will present a pilot with optimal maneuvers for missile evasion and to show the benefits of the network relative to a look-up table. They used an inductive, unsupervised learning model, which is well suited for dynamical systems and results in compact, computationally fast representations. An aircraft-missile computer simulation program is used to gather the data used in the neural network learning phase as well as in construction of the look-up table. The inputs to the neural model are variables such as aircraft velocity and initial range. Outputs are several maneuvers and associated maneuver times which provide the best chance for survival. Results show that a polynomial network can be generated that performs calculations approximating a simulator approximately a million times faster for the case of determining whether a aircraft needs to respond to a missile attack. Computer experiments suggest that for simple decision cases any of the three approaches are likely to be adequate: run a simulator in realtime, use a look-up table of precomputed runs, or use a polynomial network to approximate the simulator computations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Experimental investigation on ultra-wideband radar characteristics of coating RAM's targets (1992)

The authors have built a system of impulse radar, and made experimental investigation of a RAM coating on the surface of metallic targets, recording their echo signal data, evaluating the impulse response of the targets, and computing the energy of scattering echo and the power spectral density. The results show that ultrawideband radar has good capabilities to combat the RAM compared with the narrowband radar.
A clean-lead factory is available for lead-acid batteries recycling by means of the "cleanlead process" (2006)

The lead-acid battery recycling is a major industrial activity (more than four million tonnes recycled lead per year) that generates large amounts of toxic wastes such as lead slag, mattes and acidic sludge, besides airborne emissions. This is a waste-producer industry that needs a definitive solution to avoid its negative environmental impact and getting a sustainable lead production. That is the principal target of the CLEANLEAD technology, which properly combines both hydrometallurgical and pyrometallurgical routes aiming to get zero-waste production, reducing the use of energy and resources in all phases of battery reprocessing, and consequently, greatly decreasing the operating cost. There will be no toxic emissions to land, water or air, and obtained products are pure lead metal or pure lead oxide, and commercial gypsum instead of waste sludge. \n Achievements after pilot plant trials of this new process were quite satisfactory, and preliminary economic estimate gave positive results, opening the way to further developments and potential applications.
Intermediate spoofing strategies and countermeasures (2013)

Intermediate spoofing can impact most off-the-shelf Global Navigation Satellite Systems (GNSS) receivers, therefore low cost detection of such spoofing is very important to protect the reliability of the GNSS receivers used in critical safety and financial applications. This paper presents two strategies to analyze attacks by intermediate spoofing attackers to identify the weaknesses of such attacks. The analyses lead to a code and carrier phase consistency detection method with simulation results showing that this method can indicate the receiver when spoofing has occurred. The method can be used by most receivers, is inexpensive, and requires only a small software upgrade.
Biodegradation of Methyl<i>tertiary</i>-Butyl Ether (MTBE) and Other Fuel Oxygenates (2000)

Methyl tertiary-butyl ether (MTBE) has been added to gasoline in the U.S. for the last decade in order to meet the mandates of the 1990 Clean Air Act. This law decreed that gasoline sold in many locations must contain oxygenates to improve combustion and minimize air pollution. Unfortunately, this widespread use has led to the contamination of some soils and aquifers, and remediation is now required. Bioremediation has proven to be an environmentally responsible and cost-effective approach to remediating petroleum spills; this article reviews the potential that bioremediation may also be appropriate for remediating MTBE contamination. There is now good evidence that MTBE can be degraded by bacteria and fungi under aerobic conditions, and promising indications that the process also occurs under methanogenic and ferric iron-reducing conditions. Yet, apparently it is not a widespread phenomenon. The challenge is to find effective bioremediation strategies that maximize this biodegradation so that it can be used reliably in cleaning contaminated sites. Both simple biostimulation and more complex bioaugmentation protocols are being developed to meet this pressing need.
Reciprocal Epithelial: Fibroblast Interactions in the Control of Fetal and Adult Rat Lung Cells in Culture (1991)

Intercellular communication between epithelial cells and fibroblasts of the alveolar wall has been postulated from studies of lung development and repair. We examined the epithelial cell-fibroblast interactions with respect to growth control and epithelial cell function using cultured fetal and adult lung cells. The role of diffusing factor(s) as compared to direct cell-to-cell contact was studied by culturing epithelial cells either on a permeable culture well insert over fibroblasts or in co-culture with fibroblasts. The results show that the normal low proliferative rate of epithelial cells in culture is increased when exposed to fibroblast supernatants. In contrast, epithelial cells (particularly from adult lung) secrete a factor that suppresses fibroblast growth when cultured with a filter between the cell types. However, when cell-cell contact occurs in co-culture, the growth rate of fibroblasts is greatly increased. Synthesis of disaturated phosphatidylcholine by epithelial cells is increased under serum-free conditions and further rises when fetal epithelial cells are exposed to steroid-treated fibroblasts, when the cell types are separated, and when cells are in contact. This indicates that a fibroblast-derived factor stimulates epithelial differentiation, and morphologic evidence relating the appearance of lamellar bodies to the areas of direct epithelial cell-fibroblast contact was found. The results indicate the complex interdependence of these two types of cell where a secretory product of one cell or direct cell-cell contact may alter when regulatory control of the other cell type. These interactions are likely to be important in orderly development and in the reparative response of the lung to injury.
