Approach to direct coning/sculling error compensation based on the sinusoidal modelling of IMU signal (2013)

A direct coning mitigation algorithm based on the detection of a sinusoidal component in the gyro measurements is proposed. The coning error, which is one of dominant error sources affecting the accuracy of attitude computation in the inertial navigation system (INS), is induced by the sinusoidal motion such as a manoeuvre of vehicle or the vibration of a dithering of ring laser gyro. However, many researchers have developed coning error mitigation algorithms based on the higher‐order polynomial model and its correction terms are extracted from the gyro output without faithful consideration of the periodicity of motion. Hence, the authors first detect and estimate the sinusoidal components from gyro measurements, and then find the higher‐order correction terms from the estimated sinusoidal parameters. The authors also show that this algorithm can be applied to the mitigation of sculling error because of its duality to the coning motion. Simulation results show that the direct compensation algorithm works effectively for the navigation of vehicles with continuous and steady oscillations. Also, the rate table test with HG1700 inertial measurement unit (IMU) is conducted to show the effectiveness of proposed algorithm on real INS signal.
Daily Dosing of Rifapentine Cures Tuberculosis in Three Months or Less in the Murine Model (2007)

Rifapentine should no longer be viewed solely as a rifamycin for once-weekly administration. Our results suggest that treatment regimens based on daily and thrice-weekly administration of rifapentine and moxifloxacin may permit shortening the current 6 mo duration of treatment to 3 mo or less. Such regimens warrant urgent clinical investigation.
Stereochemical Control of Tricoordinate Copper(I) Complexes Based on N-(9-Alkyl-9-fluorenyl)-Substituted Heterocyclic Carbenes (2021)

Abstract A series of tricoordinate copper(I) complexes of general formula [Cu(Et F-NHC)(2,2′-dipyridylamine)][BF4], in which Et F-NHC represents an imidazol-2-ylidene ligand bearing a 9-ethyl-9-fluorenyl N-substituent have been synthesised stepwise from appropriate N-arylimidazoles. All complexes are remarkably air-stable, both in solution and in the solid state. X-ray diffraction studies revealed that in three of the complexes the fluorenylidene plane and the dipyridylamine (dpa) unit undergo intramolecular π–π stacking. The resulting bending of the fluorenilydene plane towards the metal atom is likely to contribute to maintain the trigonal planar geometry of the [Cu–C,N,N] unit upon binding of exogenous substrates, thereby considerably increasing complex stability.

Atmospheric‐pressure laser ionization: a novel ionization method for liquid chromatography/mass spectrometry (2005)

We report on the development of a new laser-ionization (LI) source operating at atmospheric pressure (AP) for liquid chromatography/mass spectrometry (LC/MS) applications. APLI is introduced as a powerful addition to existing AP ionization techniques, in particular atmospheric-pressure chemical ionization (APCI), electrospray ionization (ESI), and atmospheric pressure photoionization (APPI). Replacing the one-step VUV approach in APPI with step-wise two-photon ionization strongly enhances the selectivity of the ionization process. Furthermore, the photon flux during an ionization event is drastically increased over that of APPI, leading to very low detection limits. In addition, the APLI mechanism generally operates primarily directly on the analyte. This allows for very efficient ionization even of non-polar compounds such as polycyclic aromatic hydrocarbons (PAHs). The APLI source was characterized with a MicroMass Q-Tof Ultima II analyzer. Both the effluent of an HPLC column containing a number of PAHs (benzo[a]pyrene, fluoranthene, anthracene, fluorene) and samples from direct syringe injection were analyzed with respect to selectivity and sensitivity of the overall system. The liquid phase was vaporized by a conventional APCI inlet (AP probe) with the corona needle removed. Ionization was performed through selective resonance-enhanced multi-photon ionization schemes using a high-repetition-rate fixed-frequency excimer laser operating at 248 nm. Detection limits well within the low-fmol regime are readily obtained for various aromatic hydrocarbons that exhibit long-lived electronic states at the energy level of the first photon. Only molecular ions are generated at the low laser fluxes employed ( approximately 1 MW/cm(2)). The design and performance of the laser-ionization source are presented along with results of the analysis of aromatic hydrocarbons.

The analyses of alkyllead compounds in fish and environmental samples in Ontario, Canada (1981–1987) (1989)

Abstract Analyses of fish and other environmental samples (clams, macrophytes, sediments and waters) from areas upstream and downstream from two alkyllead manufactures beside the St Lawrence and St Clair Rivers, Ontario, show a clear indication of elevated alkyllead levels in samples near the industries. Most species of fish contained alkyllead compounds with tetraethyllead and triethyllead as the predominant forms. Most fish from the contaminated areas contained 50–75% of total lead as alkylleads. Carp, yellow perch and white sucker were generally the most contaminated species while pike, alewife and rock bass were the least contaminated. Average alkyllead levels varied from year to year but declined steadily after 1981. For example, the geometric mean of alkyllead compounds in carp from the St Lawrence River decreased from 4207 μg kg −1 in 1981 to 2000 μg kg −1 in 1982 and to 49 μg kg −1 in 1987, reflecting the reduction of alkylleads in the effluents and the closure of one of the manufactures in 1985. Alkyllead levels were consistently lower in muscle and carcass samples in comparison with whole fish containing fatty intestines. However, muscle levels were generally equal to carcass levels. The concentrations of alkyllead compounds were generally low in clams, macrophytes, sediments and waters except from the immediate vicinity of the manufactures' final effluent discharges.
Chronix: long term storage and retrieval technology for anomaly detection in operational data (2017)

Anomalies in the runtime behavior of software systems, especially in distributed systems, are inevitable, expensive, and hard to locate. To detect and correct such anomalies (like instability due to a growing memory consumption, failure due to load spikes, etc.) one has to automatically collect, store, and analyze the operational data of the runtime behavior, often represented as time series. There are efficient means both to collect and analyze the runtime behavior. But traditional time series databases do not yet focus on the specific needs of anomaly detection (generic data model, specific built-in functions, storage efficiency, and fast query execution).

The paper presents Chronix, a domain specific time series database targeted at anomaly detection in operational data. Chronix uses an ideal compression and chunking of the time series data, a methodology for commissioning Chronix' parameters to a sweet spot, a way of enhancing the data with attributes, an expandable set of analysis functions, and other techniques to achieve both faster query times and a significantly smaller memory footprint. On benchmarks Chronix saves 20%-68% of the space that other time series databases need to store the data and saves 80%-92% of the data retrieval time and 73%-97% of the runtime of analyzing functions.
SYNTHESIS OF (6-<sup>2</sup>H)- AND 6-DEOXY-6-FLUORO-<scp>L</scp>-GALACTOSE DERIVATIVES<sup>1</sup> (2001)

The selective oxidation of trimethylsilylated D-galactose diethyl dithioacetal using Collins reagent provided the corresponding D-galacto-hexo-dialdo dithioacetal. Successive acid hydrolysis, isopropylidenation, and cleavage of the dithioacetal group gave the 1,2;3,4-di- O-isopropylidene-L-galacto-hexodialdo-1,5-pyranose as a key intermediate for the synthesis of 6-fluoro-and 6-deutero-substituted L-fucose derivatives.
P4‐220: DEVELOPMENT OF TRYPTOPHAN‐BASED BETA‐AMYLOID ANTI‐AGGREGANTS (2014)

As part of our ongoing search to identify “endogenous anti-Alzheimer's molecules” within the human brain we have focussed on indoleamine-2,3-dioxygenase [IDO] and tryptophan [trp]. Although the essential amino acid trp can be metabolised via different pathways, a major route is the kynurenine pathway; IDO is the first enzyme of the pathway and is strongly stimulated by inflammatory molecules, particularly within the innate immune system. Various immunohistochemistry studies have demonstrated that the density of IDO-immuno-positive cells is significantly higher in both human brain with Alzheimer's disease [AD] and AD mice brain, suggesting that IDO-mediated activation of trp catabolism may be involved in amyloid aggregation and in neurofibrillary tangle formation. Accordingly, we sought to design trp analogues as possible anti-protein misfolding agents. We designed analogues of trp as putative IDO inhibitors. This was achieved by two approaches: a) designing analogues of trp by replacing functional groups with trp using bioisosteric replacements (e.g. tetrazole replacing carboxylate); or b) molecular modelling of the IDO enzyme active site. Compounds were synthesized, purified and evaluated in a battery of in vitro assays. Thirty five monocyclic heteroaromatic analogues of trp were synthesized (different from bi-aromatic analogues previously prepared by us). Eight of these analogues demonstrate micromolar/sub-micromolar efficacy in the following in vitro assays: [i] inhibiting Aβ-mediated increase in IL-1β, IL-4, IL-6, and/or TNFα cytokine release from neural tissue; [ii] inhibiting Abeta and tau aggregation (thioflavin-T Abeta aggregation fluorescence assay, thioflavin-S tau aggregation fluorescence assay, [iii] preventing Abeta conformational change to beta-sheet in circular dichroism, [iv] blocking Abeta misfolding in electron microscopy Abeta aggregation and Abeta42 biotinylated oligomerization assays; [v] able to cross the blood-brain barrier in both in vitro and in vivo models (MDR1-MDCK, mouse brain exposure PK with brain/plasma B/P >1). Two compounds demonstrated in vivo efficacy (radial arm water maze, Morris water maze) in APP/PS1 doubly transgenic amyloid mouse model of AD. IDO is a druggable target for the identification of new chemical entities as putative therapeutics for AD. Analogues of trp designed to inhibit IDO have in vitro and in vivo efficacy in the prevention of Abeta and tau misfolding.

A robust non-iterative method for image labelling using context (2002)

An innovative approach is proposed to overcome the usual drawbacks of computation complexity and insufficient robustness that affect most of contextual image segmentation techniques. Through the definition of a new connectivity measure for fuzzy image subsets, a transformation of the original set of grey levels is performed that makes it simpler to outline region boundaries. It is demonstrated that there is no need of iterations to efficiently propagate global contextual information. Some results are presented that prove the effectiveness of the method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The optokinetic nystagmus and ocular pigmentation of hypopigmented mouse mutants (1985)

We tested the optokinetic nystagmus (OKN) reflex of various hypopigmented mutant mice and ultrastructurally examined the pigmentation of various ocular structures in these mutants. Using electron microscopy we examined the pigmentation of the choroid and retinal pigment epithelium (RPE) and measured the numerical density, volume density, and distribution of RPE melanosomes of mice with the following phenotypes: (1) wild type, (2) mutants that have abnormal or no OKN in response to horizontally moving, full-field stimulation, and (3) other mutants that have normal OKN but reduced choroidal pigmentation. We also measured the OKN of all these mice in response to horizontally moving stimuli that were restricted to the nasal or to the temporal retina. We found that in the mutants with normal OKN the numerical density of melanosomes in the RPE was within the range found for wild type, while the numerical density was reduced for the mutants with abnormal OKN. For one mutant with normal RPE pigmentation and normal OKN, the choroidal pigmentation was nearly absent. For the genotypes with abnormal OKN the volume density of the RPE melanosomes and percent apical melanosomes were sometimes greater and sometimes less than normal. The OKN patterns of these mice fell into the following categories: (1) wild type; (2) field-restriction dependent OKN with small following movements but no OKN in response to full-field stimulation, normal OKN in response to stimulation of the nasal retina, and OKN of reversed direction in response to stimulation of the temporal retina; (3) oblique with slow oblique following movements and reduced numbers of OKNs with oblique quick phases in response to horizontally moving, full-field stimulation, nearly normal OKN in response to stimulation of the nasal retina, and OKN of reversed direction in response to stimulation of the temporal retina. The horizontal component of the oblique response to full-field stimulation was in the same direction for the two eyes, but the vertical component was in the opposite direction. (4) Slow, small amplitude, with no or very small following movements in response to full-field stimulation, following movements in response to stimulation of the nasal retina and reversed "following" movements in response to stimulation of the temporal retina but few or no quick phases of the OKN for any stimulus condition. These results show that a variety of abnormalities of the OKN occur for hypopigmentation mutants of the mouse.(ABSTRACT TRUNCATED AT 400 WORDS)
Field assessment of trace element uptake by six vegetables from N‐Viro Soil (1997)

A field experiment was conducted to measure the uptake of selected trace elements (Cd, Cu, Ni, Pb, and Zn) by six vegetable crops (cabbage, carrot, dry bean, lettuce, potato, and tomato) from a single large (500 mt/ha) application of N‐Viro Soil, an advanced alkaline stabilized biosolids product. Crops were grown for 3 yr (1993, 1994, 1995) after application of the biosolids in 1992. Differences among the metals for uptake by the different crops were consistent and were overall in the order: Zn > Cu > Ni > Cd > Pb. This reflects both the total soil content (Zn > Pb > Ni = Cu > Cd) and intrinsic solubilities of the metals in soil (Cd > Zn > Cu > Ni > Pb). Trace element plant uptake declined from 1993 to 1995. In general, lettuce, bean, and tomato had the highest relative trace element concentrations and cabbage the lowest, and the carrot and potato peels were elevated only in Pb compared with the flesh. Plant uptake response slopes were low compared with literature values and often negative, and the results suggest that large applications of the test material pose no threat to the food chain from trace element uptake by crops.
Going Beyond the Coinbase Transaction Fee (2016)

The blockchain technology has emerged as a disruptive technology in recent years. The open and transparent nature of the distributed ledger, as supported by the blockchain technology, is an appealing factor to push this technology in applications with strong accountability and audit requirements such as cryptocurrency systems (i.e. Bitcoin) and ecommerce (i.e OpenBazaar). In order to guarantee the integrity of the distributed ledger, a set of miner nodes is in place that uses computing power to prove the authenticity of the ledger, in exchange for a small compensation fee. In this paper, alternative reward schemes for the miners are presented.
Characterization of Plasma Shock Waves and Cavitation Bubbles Produced by a High Energy Laser Pulse through Optical and Electronic Techniques (2018)

Laser shock peening (LSP) is an established mechanical surface treatment technology. In the last years, some works have presented satisfactory results in the characterization of shock waves and plasma produced by high-energy laser pulses. These results contribute for the understanding of the LSP process. In this work, we present experimental results of the characterization of the plasma shock wave and cavitation bubbles produced by a high-energy laser pulse using optical beam deflection system, piezoelectric sensors (PZT) and strain gauges. The experimental process was carried out using Q-switched Nd:YAG laser, operated at two wavelength of 532 nm and 1064 nm with an energy of 0.5 and 1 J/pulse in single shot. These results can be applied to calculate some parameters used in the Laser Shock Processing simulation process.
Successful embolization of Rasmussens aneurysm for severe haemoptysis (2004)

A 56 year old man with a history of smoking related COPD was admitted to our hospital with a one week history of worsening chronic cough with the recent development of haemorrhagic phlegm and a subfebrile state. Chest x-rays showed a cavitary infiltrate in the left upper lobe, a right pleural effusion and bilateral mediastinal partially calcified enlarged lymph nodes. Direct sputum examination was positive for M. tuberculosis and was confirmed by culture. Eight days after initiation of a standard four drug antituberculosis treatment regime the patient presented with repeated and major haemoptysis of up to 200 ml/event. Chest x-ray showed a new air fluid level in the left superior cavity. A CTscan of the thorax disclosed a voluminous Rasmussen’s pseudoaneurysm (figure 1). Selective catheterization using a femoral approach to the left apical superior pulmonary artery showed the pseudoaneurysm arising from a subsegmental branch (figure 2). The branch was selectively embolized with 3 coils (0.035 inches 5–3 mm in diameter [COOK, Bloomington, Indiana, USA]) resulting in occlusion of this segmental branch and no filling of the pseudoaneurysm (figure 2). Haemoptysis stopped and over the next few days sputum became negative for acid fast bacilli. No further surgical intervention was performed. Chest x-ray after one year follow-up showed resolution of the cavitary lesion and no recurrence of haemoptysis. Standardized tuberculosis treatment with a four drug regime (isoniazid – rifampicin – pyrazinamide – ethambutol) over two months followed by four months of a two drug regime (isoniazid – rifampicin) was successfully completed and the patient was declared cured at the end of the treatment (1 direct exam and 2 negative cultures before the end of the treatment) [1].
Ultrasonic rock sampling using longitudinal-torsional vibrations (2010)

In recent years several European and US space projects have been focused on the development of surface rovers for planetary missions, such as ExoMars and Mars Exploration Rovers. The main function of these vehicles consists of moving across planet surfaces, and drilling and retrieving samples for in-situ analysis. Recent research has shown that drilling of rock materials can be achieved using axially oscillating tuned devices which, compared with conventional rotary drills, operate at lower power and highly reduced preload requirements. As a result, at present, ultrasonics is considered a very promising technology for exobiological prospecting. In this work, two novel ultrasonic rock samplers, both operating in a longitudinal-torsional composite mode, are proposed along with the conceptual design of a full coring apparatus, for preload delivery and core removal. To assess the penetration capability of the excited composite vibrations, preliminary drilling trials were conducted. Since sand constitutes a significant portion of the Martian surface, sandstone was used in the trials.

Combustion Technology of Coal Water Slurry at Caustic Soda Vaporizing Furnace (2007)

A new clean coal-based liquid state fuel-coal water slurry is reported and it′s application on caustic soda furnace is also discussed. In order to carry out CWS combustion,it is necessary to simply change the furnace.For example,a smooth burning combustor and a CWS system of discharge,store and transmit must be added.The results show that the combustion efficiency is over 97%,the combustion temperature can be adjusted flexible and system operation is safe and reliable.There is great economic benefit and environment improvement for CWS burning.
