Gas-Phase Oxidation and Nitration of First-, Second-, and Third-Row Atomic Cations in Reactions with Nitrous Oxide:  Periodicities in Reactivity (2004)

Room-temperature reactions of 46 different atomic cations with N2O have been surveyed systematically using an inductively coupled plasma/selected-ion flow tube (ICP/SIFT) tandem mass spectrometer. The atomic cations are produced at about 5500 K in the ICP source and are allowed to decay radiatively and thermalize by collisions with Ar and He atoms prior to reaction. Rate coefficients were measured for the reactions of first-row atomic cations from K+ to Se+, of second-row atomic cations from Rb+ to Te+ (excluding Tc+), and of third-row atomic cations from Cs+ to Bi+. Primary reaction channels were observed corresponding to O-atom transfer, N-atom transfer, and N2O addition. Periodicities were observed in overall reaction efficiency, and these are scrutinized in terms of overall exothermicity, the presence of an activation barrier in the reaction coordinate, and the overall conservation of spin. N-atom transfer was observed to compete with O-atom transfer in the reactions of N2O with La+ (4%), Ti+ (22%), Zr+ (45%), Nb+ (35%), Ta+ (40%), and Os+ (60%). Up to three N2O molecules were observed to add sequentially to selected atomic cations as well as several monoxide and dioxide cations. A second O-atom transfer was observed with the group 4, 5, and 6 transition-metal ions (except Mo+) as well as the third-row cations Re+, Os+, Ir+, and Pt+. The atomic ions W+, Os+, and Ir+ formed trioxides in sequential O-atom transfer reactions, and Os+ even formed the tetroxide OsO4+. Multicollision-induced dissociation studies with Ar buffer gas indicated thermodynamically controlled dissociation of TiO2+, ZrO2+, HfO2+, VO2+, NbO2+, TaO2+, and WO2+ by the consecutive detachment of O-atoms while CrO2+, ReO2+, and PtO2+ decomposed primarily by loss of O2 molecules.

Live Blackboxes: Requirements for Tracking and Verifying Aircraft in Motion (2017)

The Malaysian Airlines (MH370) aircraft went missing somewhere over the Indian Ocean two years ago. After intensive search since then, international team still has not been able to locate any first-hand evidence from the missing plane's flight data recorders (also known as ‘blackboxes'). To mitigate similar problems, a proposal has been made to analyse live streamed flight data using cloud computing; however, satellite communication is constrained by bandwidth and scalability challenges. In this paper, we propose five requirements for addressing these challenges. These requirements frame a class of monitoring problems that share some similar accuracy concerns around safety and security. We evaluate these requirements to assess the readiness of the proposed technology - which we call “live blackboxes" by using actual global scale data and performing an analysis of different live streaming intervals. Preprocessing with a locality-sensitive hashing function, it results in reduction of the required bandwidth by 4.75 times. Therefore, to track and verify all civilian aircraft in motion, the scalability requirement could be satisfied by satellite communications. While the paper focuses on a particular problem in air traffic management, we speculate similar requirements for the continuous monitoring of critical systems.
Compact Vehicular Trajectory Encoding (2011)

Many applications in vehicular communications require the collection of vehicular position traces. So far this has been done by recording and transmitting unencoded or merely linearly filtered position samples. Depending on the sample frequency and resolution, the resulting data load may be very large, consuming significant storage and transmission resources. In this paper, we propose a method based on two-dimensional cubic spline interpolation that is able to reduce the amount of the measurement data significantly. Our approach allows for a configurable accuracy threshold and performs in O(n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> ). We evaluate our approach with real vehicular GPS movement traces and show that it is able to reduce the volume of the measurement set by up to 80% for an accuracy threshold of 20 centimeters.

Electrogenerated Chemiluminescence of a Spirobifluorene-Linked Bisanthracene: A Possible Simultaneous, Two-Electron Transfer (2008)

We report the electrogenerated chemiluminescence (ECL) of 2,2'-bis(10-phenylanthracen-9-yl)-9,9'-spirobifluorene (spiro-FPA), a dichromophoric molecule composed of two phenylanthracenes linked by a spirobifluorene moiety (PA-X-PA). The results are compared to those for 9,10-diphenylanthracene (DPA), a related molecule with a single chromophore. Cyclic voltammetry (CV) of spiro-FPA shows two reversible, closely spaced, one-electron transfers on both reduction and oxidation, occurring at E(o)(1,red) = -2.02, E(o)(2,red) = -2.07 V vs SCE and E(o)(1,ox) = 1.14, E(o)(2,ox) = 1.20 V vs SCE. The potentials for each pair are close enough to appear as a single peak in CV, indicating that the spirobifluorene moiety interrupts conjugation between the redox centers. The potentials observed are similar to those of DPA, which shows E(o)(red) = -2.06 V vs SCE and E(o)(ox) = 1.15 V vs SCE. The absorbance spectrum of spiro-FPA shows lambda(max,abs) = 377 nm, with 377 = 25,700 M(-1) s(-1), while DPA exhibited lambda(max,abs) = 374 nm, with 374 = 13,800 M(-1) s(-1), demonstrating that spiro-FPA has twice the available chromophores as DPA. Photoluminescence (PL) data for spiro-FPA shows lambda(max,PL) = 434 nm, with Phi(PL) = 0.74, while DPA fluoresces at 420 nm with Phi(PL) = 0.91; thus, there is greater solvent or structural relaxation in the spiro-FPA excited state, which may account for the greater internal conversion. Unlike DPA, the ECL spectrum of spiro-FPA exhibits long-wavelength emission not observed in the PL. We attribute this emission to excimers formed during annihilation ECL. Steric hindrance prevents DPA from forming excimers, even in ECL, but spiro-FPA annihilation can occur between pairs of di-ions (PA(*-)-X-PA(*-) and PA(*+)-X-PA(*+)), which are electrostatically more strongly attracted to one another than the mono-ions. This greater electrostatic attraction may be sufficient to overcome the steric hindrance to excimer formation. Lowering the electrolyte concentration decreases the electrostatic shielding of the ions from one another; thus, the increase in longer wavelength ECL accompanying a decrease in electrolyte concentration supports the role of the di-ions in excimer formation. Additionally, simulations show, consistent with experiment, a more rapid decrease in excimer concentration than in excited monomer concentration as a function of time after each potential pulse. This is probably due to the greater number of scavenging reactions available for di-ions. The simulations are confirmed experimentally when lower potential pulsing frequencies yield lower relative excimer emission. Since an excited state created by one-electron transfer between two di-ions should be rapidly quenched via electron transfer by the other PA moiety, the existence of excimers suggests the possibility of simultaneous, two-electron transfer to generate the excimer.
<title>Stellar coronagraph for the New Technology Telescope</title> (1994)

The stellar coronograph built by STScl and the OATO operating at the SUSI focus of ESO's New Technology Telescope (NTT), described with particular emphasis on its optical and mechanical characteristics, is one of the most powerful coronographs in operation. Observations with angular resolutions of 0.6 arcsec over field of view of 45 arcsec diameter have been routinely achieved in the observing runs carried out so far. We describe the results from the application of the coronograph to the problem of observing the inner regions in the (beta) Pictoris dust disk.
J043033 A fundamental study on electric resistance welding of CFRTP (2011)

In this study, a new welding method which utilizes conductivity of CFRTP (Carbon fiber reinforced thermoplastic) is proposed. Electrical current is applied through the CFRTP single-lap joints in thickness direction. Since resistance of joining surface is the highest in the current path, the joining surface is preferentially heated by Joule heating. In this study, spot welding and surface welding were conducted. By applying constant voltage of 5.0V or ,10.3V, the joint-surfaces were heated above glass transition temperature of the material and were welded. In order to evaluate lap-shear strength (LSS) of welded joints by proposed method, tensile lap-shear tests were conducted. As a result, the tensile lap-shear true stress of spot welding is 31.0MPa and nominal stress of surface welding is 22.0MPa (CF Fabric/PEI) and 21.6MPa (CF Fabric/PPS) . These strengths were comparable to those that were welded by traditional resistance welding (19-22MPa) . It is also found that LSS is changed with welding pressure of joint parts.
Quantitative CT for determination of bone mineral density: a review. (1988)

One of the major uses of quantitative computed tomography (CT) has been the measurement of bone mineral density (BMD) at various skeletal sites. The published literature on this subject from 1974 to the present is extensive. Because many investigators and clinicians are just now starting to explore the utility of this technique, the author reviewed this literature to provide both the historic perspective and current status of BMD measurement with CT. The physical and physiologic bases of the method, accuracy, reproducibility, radiation dose, and clinical utility are all discussed.

THE COLLABORATIVE AGING RESEARCH USING TECHNOLOGY (CART) INITIATIVE: DIVERSE COHORTS (2018)

The CART initiative emphasizes real-world scalability and addressing the needs of diverse populations. To this end, the project is enrolling volunteers (couples and those living alone) to participate in the initiative consenting to have the CART suite of technologies installed in their home while relevant clinical data is collected informing primarily the degree to which key functional abilities and health and wellness traits are captured. Four sites represent key constituencies that have not previously been widely included in pervasive computing research including older adults: 1) of low-income (living in section 202 housing in Portland, Oregon); 2) who are African Americans (participating in the Minority Aging Research Study in Chicago); 3) of Spanish-speaking heritage (in Miami, Florida); and 4) rural-residing veterans (living in the northwest Veterans Service Network area 20). The presentation will review enrollments to date focusing on the process of enrollment and preliminary experience with the CART system.
Stockage et stabilité à long terme de boues d’épuration municipales décontaminées et stabilisées par voie chimique ou biologique (2008)

The objective of this research was to evaluate the effects of sewage sludge storage on biological and physico-chemical parameters of sludge treated by different stabilization and decontamination processes. Three sludge storage methods were tested: inside at stable temperature (21 ± 2 °C), outside during summer (May–October), and inside at different temperatures to simulate the winter season. An increase of the sludge pH (approximately 8.0–8.5) and an odour removal process were measured following a 5-month storage period, and this, for all conditions of sludge treatments and storage options. The sanitary conditions of the sludge improved, because the fecal coliforms were completely eliminated, and fecal streptococci and salmonella were significantly reduced. The results also revealed that the pH adjustment, near neutrality, of sludge treated by acid processes (Stabiox and Metix-AC) is preferable before a long storage period. This allows a better biodegradation of the organic matter and the production of less odorous sludge. Sludge neutralization also decreases phosphorus and metals concentrations in drainage waters. The preservation of the acid conditions remains however useful during a short storage period, by allowing to avoid a fast resumption of the nauseous odours. Overall, the different temperatures had few effects on sludge characteristics after the 5-month storage period.
Human Robot Interaction on Navigation platform using Robot Operating System (2020)

In the last few decades, automation has been one of the leading and emerging technologies to develop sophisticated and robust robotic solutions for various applications like military, agriculture, transport, shopping, house, hospitals, etc. One of these emerging fields is service robotics which is implemented in the shop, home, and hospital environments. As these domains deal with the interaction between Humans and Robots, the concept called Human-Robot Interaction (HRI) has come into existence. In service robotics, voice is the most important mode of communication for HRI. This research proposes the implementation and integration of such HRI on an autonomous navigation system using the Robot Operating System (ROS). This paper also discusses the system architecture that is developed for this research.
An acousto-optic real-time ’’two-crystal’’ correlator (1978)

A real-time correlator has been developed that utilizes successive acousto-optic interactions in two adjacent piezoelectric crystals (lithium niobate, LiNbO3, and bismuth germanium oxide, BGO) having surface-acoustic-wave (SAW) propagation velocities that differ by almost a factor of 2. Complex waveforms, such as FM chirps and Barker codes, have been correlated successfully. A large time-bandwidth product (∼3000) was obtained, and a 40-dB dynamic range was shown to be feasible. The use of this two-crystal device to obtain either pulse expansion or time inversion of a signal also was demonstrated.
Mathematical modelling of platelet rich plasma clotting. Pointwise unified model (2018)

Abstract The mechanistic modelling of blood clotting and fibrin-polymer mesh formation is of significant value for medical and biophysics applications. This paper presents a combination of two pointwise kinetic models represented by system of ODEs. One of them represents the reaction dynamics of clotting factors including the role of the platelet membranes. The second one describes the fibrin-polymer formation as a multistage polymerization process with a sol-gel transition at the final stage. Complex-value second order Rosenbrock method (CROS) is employed for the computational experiments. A sensitivity analysis method built into the computational scheme helps clarify non-evident dependencies in the exhaustive system of ODEs. The unified model was primarily verified using conditions of factor VII deficiency. The model, however requires a significant effort to be tested against experimental data available.

FcγRIIIb Restricts Antibody-Dependent Destruction of Cancer Cells by Human Neutrophils (2019)

The function of the low-affinity IgG-receptor FcγRIIIb (CD16b), which is uniquely and abundantly expressed on human granulocytes, is not clear. Unlike the other Fcγ receptors (FcγR), it is a glycophosphatidyl inositol (GPI) -anchored molecule and does not have intracellular signaling motifs. Nevertheless, FcγRIIIb can cooperate with other FcγR to promote phagocytosis of antibody-opsonized microbes by human neutrophils. Here we have investigated the role of FcγRIIIb during antibody-dependent cellular cytotoxicity (ADCC) by neutrophils toward solid cancer cells coated with either trastuzumab (anti-HER2) or cetuximab (anti-EGFR). Inhibiting FcγRIIIb using CD16-F(ab')<sub>2</sub> blocking antibodies resulted in substantially enhanced ADCC. ADCC was completely dependent on FcγRIIa (CD32a) and the enhanced ADCC seen after FcγRIIIb blockade therefore suggested that FcγRIIIb was competing with FcγRIIa for IgG on the opsonized target cells. Interestingly, the function of neutrophil FcγRIIIb as a decoy receptor was further supported by using neutrophils from individuals with different gene copy numbers of <i>FCGR3B</i> causing different levels of surface FcγRIIIb expression. Individuals with one copy of <i>FCGR3B</i> showed higher levels of ADCC compared to those with two or more copies. Finally, we show that therapeutic antibodies intended to improve FcγRIIIa (CD16a)-dependent natural killer (NK) cell ADCC due to the lack of fucosylation on the N-linked glycan at position N297 of the IgG<sub>1</sub> heavy chain Fc-region, show decreased ADCC as compared to regularly fucosylated antibodies. Together, these data confirm FcγRIIIb as a negative regulator of neutrophil ADCC toward tumor cells and a potential target for enhancing tumor cell destruction by neutrophils.
Content Rating Technique for Cloud-Oriented Content Delivery Network Using Weighted Slope One Scheme (2018)

Arguably, the rise in global population has been matched by the rapid rate of expansion of internet. Today, some of the prominent companies in information and media technology rely on content and advertising to fuel their growth. On the other hand, the insatiable thirst for information coupled with an incessant urge for instant consumption of digital media have made it impossible to overlook content delivery networks. As a cost-effective and robust means, cloud-based content delivery network (CCDN) service has considerable advantages. At the core of a CCDN service, lies a cloud-based data center infrastructure. This makes it possible to distribute content load over a large number of storage servers situated at various geographical locations. However, close on the heels of the advantages offered by CCDN service, comes an interminable challenge to stay ahead of high latency when meeting content delivery requests. We propose a collaborative filtering algorithm using weighted slope one method as a model to arrest network latency and optimize storage requirements. Our model demonstrates that it is able to stay ahead of over fitting, and increase accuracy of the results yielded. Using our approach, CCDN service providers will be able to boost content delivery speeds through determination of storage requirements in a flexible and cost-effective manner.
Inducing CCR5Δ32/Δ32 Homozygotes in the Human Jurkat CD4+ Cell Line and Primary CD4+ Cells by CRISPR-Cas9 Genome-Editing Technology (2018)

C-C chemokine receptor type 5 (CCR5) is the main co-receptor for HIV entry into the target CD4+ cells, and homozygous CCR5Δ32/Δ32 cells are resistant to CCR5-tropic HIV infection. However, the CCR5Δ32/Δ32 homozygous donors in populations are rare. Here we developed a simple approach to induce CCR5Δ32/Δ32 homozygotes through CRISPR-Cas9 genome-editing technology. Designing a pair of single-guide RNA targeting the flank region of the CCR5Δ32 mutation locus, we applied the CRISPR-Cas9 and lentiviral packaging system to successfully convert wild-type CCR5 into CCR5Δ32/Δ32 homozygotes in the human Jurkat CD4+ cell line and primary CD4+ cells, exactly the same as the naturally occurring CCR5Δ32/Δ32 mutation. The successful rate is up to 20% in Jurkat cells but less in primary CD4+ cells. The modified CCR5Δ32/Δ32 CD4+ cells are resistant to CCR5-tropic HIV infection. Whole-genome sequencing revealed no apparent off-target sites. This approach has the promise to promote HIV/AIDS therapy from the only cured unique Berlin patient to a routine autologous cell-based therapy.
