Pressure/Pressure Convolution Analysis of Multiprobe and Packer-Probe Wireline Formation Tester Data (2004)

Summary In cases in which flow-rate data are not reliable, the need for flow rate in estimating permeability from wireline formation tester multiprobe and packer-probe pressure-data sets can be eliminated by the use of the so-called pressure/pressure (p/p) convolution. The p/p convolution is based on the use of different pressure-data sets recorded at two different spatial locations and thus enables one to perform parameter estimation without flow rate. In this work, we present a detailed analysis of multiprobe and packer-probe pressure-transient tests by considering various p/p convolution options for both single-layer and multilayer systems. Approximate equations that apply during spherical and radial flow for a vertical well in a single-layer system for various p/p convolution options are derived. These equations indicate which parameters can be determined uniquely from p/p convolution. It is shown that p/p convolution analysis sometimes may not provide unique parameter estimates. Also, we provide a flow-rate-estimation method that proves useful to check the validity of parameter estimates obtained from p/p convolution analysis. Two example tests, a synthetic multiprobe test and a field packer-probe test, are given to illustrate the methodology and procedures developed in this work.
Nature-inspired techniques for the synthesis of aperiodic ultra-wideband phased arrays (2010)

Over the past few decades, much research has been invested in the exploration of wideband and ultrawideband (UWB) antenna arrays. The goals of such array designs are to determine the best element arrangements that yield radiation patterns possessing the highest degrees of sidelobe suppression and no grating lobes over the largest possible operating bandwidths. It has been recently shown that nature-inspired array design methodologies can provide solutions that exhibit these ultra-wideband characteristics. An overview of several new array design techniques is given here; linear polyfractal arrays, linear raised-power series (RPS) arrays, compact linear UWB design, and planar arrays of aperiodic tilings. Robust nature-inspired genetic algorithm optimization techniques and other evolutionary strategies were utilized in the design of these types of arrays in order to obtain the best possible UWB performance.

Acoustic Impulse Response Interpolation for Multichannel Systems Using Dynamic Time Warping (2009)

We present a method of interpolation of room acoustic impulse responses for reducing measurement sets in multichannel convolution systems. The method employs the use of Dynamic Time Warping for the synthesis of early reflections and critical band analysis for diffuse decay decorrelation. An objective study of the reduced data sets in comparison to full spatial resolution measurements taken in a reverberant environment is presented through binaural measurements. Listening tests are conducted under controlled conditions for investigation into the perceptual attributes associated with the synthesized audio.
Combined analysis of all three phases of solar neutrino data from the Sudbury Neutrino Observatory (2013)

We report results from a combined analysis of solar neutrino data from all phases of the Sudbury Neutrino Observatory (SNO). By exploiting particle identification information obtained from the proportional counters installed during the third phase, this analysis improved background rejection in that phase of the experiment. The combined analysis of the SNO data resulted in a total flux of active neutrino flavors from ${}^{8}\mathrm{B}$ decays in the Sun of $(5.25\ifmmode\pm\else\textpm\fi{}0.16{(\mathrm{stat}.)}_{\ensuremath{-}0.13}^{+0.11}(\mathrm{syst}.))\ifmmode\times\else\texttimes\fi{}{10}^{6}\phantom{\rule{0.16em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}2}{\mathrm{s}}^{\ensuremath{-}1}$, while a two-flavor neutrino oscillation analysis yielded $\ensuremath{\Delta}{m}_{21}^{2}=(5.{6}_{\ensuremath{-}1.4}^{+1.9})\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}\phantom{\rule{0.16em}{0ex}}{\mathrm{eV}}^{2}$ and ${\mathrm{tan}}^{2}{\ensuremath{\theta}}_{12}=0.{427}_{\ensuremath{-}0.029}^{+0.033}$.

Efficient stack-less BVH traversal for ray tracing (2011)

We propose a new, completely iterative traversal algorithm for ray tracing bounding volume hierarchies that is based on storing a parent pointer with each node, and on using simple state logic to infer which node to traverse next. Though our traversal algorithm does re-visit internal nodes, it intersects each visited node only once, and in general performs exactly the same ray-box tests and ray-primitive intersection tests---and in exactly the same order---as a traditional stack-based variant. The proposed algorithm can be used for computer architectures that need to minimize the use of local memory for processing rays or those that need to minimize the data transport such as distributed multi-CPU architectures.
Human Embryonic vs Adult Stem Cells for Transplantation Therapies (2003)

Cells are the fundamental units of life, the building blocks of all tissue, and the source of all extracellular matrix and interstitial fluids. It is clear that irreversible loss of cells as a result of intrinsic or extrinsic causes can be permanently debilitating or lethal. Examples include loss of islet β–cells (diabetes), cardiomyocytes (heart failure), neurons (Parkinsons, dementias, ataxia, stroke, paralysis), hepatocytes (cirrhosis), chondrocytes (joint diseases), renal cells (kidney failure), and hematopoietic cells (bone marrow failure, anemias). Although traumatic cell loss can occur at any age, as demographics in developed countries shift gradually to older individuals, the most significant unmet clinical need and health care burden will likely be chronic diseases in the elderly in which the underlying etiology is cell aging or degeneration.

Creative usage of stator flux linkage to fast brake electric vehicles (2016)

Kinetic energy has to be rapidly transferred or dissipated in order to quickly brake an electric vehicle. In electric vehicles, a finite amount of kinetic energy can be transferred to the battery. Motor braking capability is fundamentally limited by the maximum charging rate and the state-of-charge of the battery. This paper presents a methodology to manipulate system losses such that the additional kinetic energy can also be dissipated in the motor and the inverter, eventually in the cooling system. To do this, stator flux linkage is dynamically varying while torque control accuracy is not compromised. The achieved additional torque can assist to brake electric vehicles faster with fully-charged batteries, as well as in emergency situations. The maximum braking torque is affected by the current limit, DC bus voltage and the peak power that energy storage system can absorb. Analytical and experimental evaluation is provided to quantitatively examine the additional braking torque.
Mode-Locked Oscillation of Cr:ZnS Laser using a Single Walled Carbon Nanotube Film with Resonant Absorption at 2.4 μm (2019)

Ultrashort pulses in the mid-infrared (mid-IR) region have a great potential in the applications of advanced vibrational spectroscopy and strong field phenomena. Traditionally, mid-IR ultrashort pulses are generated by frequency conversion of near-infrared pulses from Ti:S or Yb-based lasers. Laser oscillators which directly emit mid-IR femtosecond pulses are advantageous from the perspectives of simplicity and energy extraction efficiency. Cr:ZnS is an attractive gain medium for mid-IR ultrafast lasers because it has a broad fluorescence spectrum, large stimulated-emission cross-section and high thermal conductivity [1]. So far, passive mode-locking has been realized for Cr:ZnS laser, by employing Kerr-lensing, or by using saturable absorbers based on semiconductors or graphenes [2]. A single walled carbon nanotube (SWCNT) film is also known as a good candidate for saturable absorbers, possessing tunable resonance and large modulation depth. However, SWCNTs have rarely been applied to this laser [3]. Here, we demonstrate self-starting mode-locked oscillation of Cr:ZnS laser by using a SWCNT film which has resonant absorption at the laser emission wavelength of 2.4 μm.
Search and witness problems in group theory (2010)

Decision problems are problems of the following nature: given a property and an object , find out whether or not the object has the property . On the other hand, witness problems are: given a property and an object with the property , find a proof of the fact that indeed has the property . On the third hand(?!), search problems are of the following nature: given a property and an object with the property , find something “material” establishing the property ; for example, given two conjugate elements of a group, find a conjugator. In this survey our focus is on various search problems in group theory, including the word search problem, the subgroup membership search problem, the conjugacy search problem, and others.
Modifying an Insect Cell N-Glycan Processing Pathway Using CRISPR-Cas Technology (2015)

Fused lobes (FDL) is an enzyme that simultaneously catalyzes a key trimming reaction and antagonizes elongation reactions in the insect N-glycan processing pathway. Accordingly, FDL function accounts, at least in part, for major differences in the N-glycosylation patterns of glycoproteins produced by insect and mammalian cells. In this study, we used the CRISPR-Cas9 system to edit the fdl gene in Drosophila melanogaster S2 cells. CRISPR-Cas9 editing produced a high frequency of site-specific nucleotide insertions and deletions, reduced the production of insect-type, paucimannosidic products (Man3GlcNAc2), and led to the production of partially elongated, mammalian-type complex N-glycans (GlcNAc2Man3GlcNAc2) in S2 cells. As CRISPR-Cas9 has not been widely used to analyze or modify protein glycosylation pathways or edit insect cell genes, these results underscore its broad utility as a tool for these purposes. Our results also confirm the key role of FDL at the major branch point distinguishing insect and mammalian N-glycan processing pathways. Finally, the new FDL-deficient S2 cell derivative produced in this study will enable future bottom-up glycoengineering efforts designed to isolate insect cell lines that can efficiently produce recombinant glycoproteins with chemically predefined oligosaccharide side-chain structures.
Reactions of 4-Hydroxy-2H-1,4-benzoxazin-3-one Derivatives with Some Nucleophiles (1978)

Reactions of 4-hydroxybenzoxazin-3-one(?), 4-hydroxy-7-methoxybenzoxazin- 3-one(?) and their 0-acetates(?),@),with various nucleophiles were examined.1 and its acetates(?)reacted with acetate or chloride under various con-ditions giving 6-and 7-acetoxy-or chloro-benzoxazin-3-one.The acetate (4) is very reactive, and rapidly reacted with phenol, cresols, indoles, and ethanthiol.The reaction products were analyzed.Some interesting reaction products(5-2) were shown below.These reations suggest that phytoalexins, 2,4-dihydroxybenzoxazin-3-one and 2,4-dihydroxy-7-methoxybenzoxazin-3-one, can be electrophilic chemicals.
Organoclays prepared in supercritical CO2: implication of onium stability on the properties of PA6 nanocomposites (2009)

The organomodification of layered silicates via our patented supercritical CO2 ion-exchange process, enables the use of a large variety of surfactants, among which phosphonium and ammonium ions of the very same structure. The as-obtained organoclays were melt blended with PA6 and the morphology as well as the fire properties of the nanocomposites were studied. With the same degree of nanodispersion, longer ignition times were observed with phosphonium-modified clays compared to ammonium-modified clays.

Bond strength and cement-tooth interfacial characterization of self-adhesive composite cements. (2017)

No significant differences in bonding effectiveness were recorded for the self-adhesive composite cements when bonded to unetched/etched enamel and to dentin. Multi-step etch-and-rinse composite cements showed a better bonding effectiveness to enamel, although this could be approximated by the self-adhesive composite cements when enamel was acid-etched beforehand. On dentin, however, the bond strength of the etch-and-rinse composite cement RelyX ARC was superior.
How query extensions reflect search result abandonments (2012)

It is often considered that high abandonment rate corresponds to poor IR system performance. However several studies suggested that there are so called good abandonments, i.e. situations when search engine result page contains enough details to satisfy the user information need without necessity to click on search results. In this work we propose to look at query extensions. We see that an extension by itself might motivate abandonment type (good or bad) for the underlying query to some degree. We also propose a way to find potentially good abandonment extensions in an automated manner.
Carboxylic acid derivatives via catalytic carboxylation of unsaturated hydrocarbons: whether the nature of a reductant may determine the mechanism of CO2incorporation? (2015)

Application of CO2 as a renewable feedstock and C1 building block for production of commodity and fine chemicals is a highly challenging but obvious industry-relevant task. Of particular interest is the catalytic coupling of CO2 with inexpensive unsaturated hydrocarbons (olefins, dienes, styrenes, alkynes), providing direct access to carboxylic acids and their derivatives. Although not brand new for the scientific community, it is still a complete challenge, as no truly effective catalytic system has been reported to date. In this Perspective, we discuss the available experimental, theoretical and mechanistic data for such homogeneously catalyzed carboxylation processes. A special focus is placed on the understanding of the key elementary steps and of some thermodynamic and kinetic constraints.
Metabolites and Lipids Associated with Fetal Swine Anatomy via Desorption Electrospray Ionization – Mass Spectrometry Imaging (2019)

Chemical imaging by mass spectrometry (MS) has been largely used to study diseases in animals and humans, especially cancer; however, this technology has been minimally explored to study the complex chemical changes associated with fetal development. In this work, we report the histologically-compatible chemical imaging of small molecules by desorption electrospray ionization (DESI) - MS of a complete swine fetus at 50 days of gestation. Tissue morphology was unperturbed by morphologically-friendly DESI-MS analysis while allowing detection of a wide range of small molecules. We observed organ-dependent localization of lipids, e.g. a large diversity of phosphatidylserine lipids in brain compared to other organs, as well as metabolites such as N-acetyl-aspartic acid in the developing nervous system and N-acetyl-L-glutamine in the heart. Some lipids abundant in the lungs, such as PC(32:0) and PS(40:6), were similar to surfactant composition reported previously. Sulfatides were highly concentrated in the fetus liver, while hexoses were barely detected at this organ but were abundant in lung and heart. The chemical information on small molecules recorded via DESI-MS imaging coupled with traditional anatomical evaluation is a powerful source of bioanalytical information which reveals the chemical changes associated with embryonic and fetal development that, when disturbed, causes congenital diseases such as spina bifida and cleft palate.

RAP: A Ricardian Auctioning Protocol for Demand-Supply Matching using Open Bids (2021)

In this paper, we define an auction protocol and implementation of a decentralized and distributed auctioning platform for demand-supply matching of components and materials subject to recycling. Auctioning is the process of buying and selling goods or services by offering them up for bid, taking bids, and then selling the item to a winner according to preset rules. Some auction types relies on sealed-bids while others implement an open-bid procedure that allows for multiple bids before a known or unknown deadline. The English auction and its variants is most common type. It relies on that the current highest bid is always available to potential bidders. Online auction platforms are nowadays used to trade various services and goods. We address the iterative negotiations in form of auction bids aiming at signed contractual agreements stated in legal prose and captured by Ricardian contracts. We evaluate our model towards requirements including privacy, transparency and fairness in terms of acknowledged publishing of highest bids and the ordered arrival of individual bids. In addition, we demonstrate the mechanisms for distributed storage of cryptographically signed Ricardian contracts, omitting the need for trusting the auctioneer or relying on a trusted third party for this storage.
The effects of organic vapor on alkanethiol deposition via Dip‐pen nanolithography (2010)

Dip-pen nanolithography (DPN) is a scanning probe-based technique that allows for direct delivery of molecules to a range of substrates with sub-50 nm resolution. This study describes the effect of organic solvent vapor on the deposition rate and feature size of nanostructures deposited via DPN. The transport rate of model molecular inks, 1-octadecanethiol, and 16-mercaptohexadecanoic acid were examined under atmospheres of ethanol, methanol, hexane, and dichloromethane. In all cases, presence of an organic vapor increased deposition rate and feature size, in some cases by an order of magnitude. This underscores how the environment can be used to regulate molecular transport rates in a DPN experiment.
Reply to: Misinterpretation of solid sphere equivalent refractive index measurements and smallest detectable diameters of extracellular vesicles by flow cytometry (2021)

We appreciate the critical review of our article 1 by van der Pol et al., as it provides more detailed insight into the mechanics of their modeling 2 . Fundamentally, most of their arguments boil down to a contrast between our real-world empirical data vs. their theoretical modeling, based on a variety of assumptions. We will briefly comment on their main points.
Prevalence of trichomoniasis among California beef herds (1990)

Sixty cow-half herds of more than 50 cows each were randomly selected for a prevalence survey of bovine trichomoniasis in California. Herd size, as judged by the number of bulls, ranged from 1 to 210 bulls (median = 8; mean = 59 +/- 15.8). Preputial smegma was collected from 729 bulls (median = 6 bulls/herd) and cultured for Tritrichomonas foetus. Of 57 herds from which samples were collected, 9 (15.8%) had at least one infected bull. Of the 729 bulls from which samples were cultured, 30 (4.1%) were infected. Correcting for sensitivity of the diagnostic test yielded a prevalence of 5.0%. Infection rates for bulls greater than 3 years old and less than or equal to 3 years old were 6.7% and 2.0%, respectively (P less than 0.025). Median herd sizes were 14 bulls (range, 6 to 114) for infected herds and 7 (range, 1 to 210) for uninfected herds. These findings suggest that trichomoniasis is common in California beef herds. Because several bulls less than 4 years old were infected, we suggest that control measures stressing replacement of older bulls with younger ones should be combined with diagnostic procedures in those younger replacements, to ensure that they are not already infected.
