Flame Stabilization Through Forcing: Velocity Measurements (2000)

The differences in the flow field of an unforced unstable flame and a forced stable flame was examined through velocity and temperature measurements. Measurements were made in open atmosphere with an air-assist atomizing nozzle consisting of a central liquid-fuel (ethanol) stream, and a swirling primary air stream. Measurements made include the temperature, and CH/C2 emission spectra for the forced stable flame, and cold-flow velocity measurements for both the air stream and the fuel droplets with and without primary-air forcing. The temperature distributions indicate that the stable flame is characterized by three distinct zones in the axial direction: (1) a low-temperature droplet heat-up and vaporization zone near the base of the flame, (2) an intermediate zone with three regions in the radial direction: a low-temperature droplet vaporization region straddled by two high-temperature combustion regions, one in the center and the other along the outer edges respectively, and (3) an upper high-temperature zone with combustion across the entire cross-section. The intermediate zone is most effected by forcing with substantial increases in the velocities, entrainment or volume flow rate, and turbulence levels. These increases contribute to improved vaporization and fuel-air mixing and therefore higher temperatures near the base of the flame. The forcing-induced improved mixing and the higher temperatures near the base of the flame are responsible for the flame stabilization.
Photoluminescence Quenching Control in Quantum Dot–Carbon Nanotube Composite Colloids Using a Silica‐Shell Spacer (2006)

One-dimensional nanocomposite colloids are prepared by means of electrostatic self-assembly of CdTe nanocrystals on both carbon nanotubes (CNTs) and silica-coated CNTs (see Figure). The dense coverage of these linear nanoparticle assemblies minimizes the spacing between the nanocrystals, thereby facilitating efficient electronic and energy transfer along the nanotubes.

Syntheses and radical polymerizations of methacrylamides derived from optically active amino alcohols (1997)

Abstract Syntheses and radical polymerizations of methacrylamides derived from optically active amino alcohols were carried out. The monomers were prepared by condensation of optically active amino alcohols and methacrylic acid using 1‐ethyl‐3‐(3‐dimethylaminopropyl)carbodiimide hydrochloride (EDC · HCl). Radical polymerizations of the monomers were carried out in the presence of 2,2‐azoisobutyronitrile (AIBN) (3 mol‐%) in methanol and N,N ‐dimethylformamide (DMF) as solvents, resulting with good yields in polymers with M n 's in the range 17 800–81 000. The monomer reactivity ratios of N ‐(1‐hydroxy‐4‐methyl‐2‐pentyl)methacrylamide (MA‐Lol) and methyl methacrylate (MMA) in the copolymerization were estimated to be 0.50 and 2.38, respectively. The lower reactivity of MA‐Lol in comparison with MMA is similar to common methacrylamide derivatives. The hydrophilicity of the polymers was evaluated by the heat of fusion of water using differential scanning calorimetry (DSC). The determined order poly(MA‐Aol) &gt; poly(MA‐Lol) &gt; poly(MA‐Fol) reflects the bulkiness of the side chains.
Stochastic Threshold for Ion Heating with Beating Electrostatic Waves (2013)

The stochastic threshold for the heating of ions in a magnetized plasma with two electrostatic waves is experimentally characterized. Two obliquely propagating electrostatic modes are launched in a magnetized plasma with frequencies that differ by the ion cyclotron frequency. The values of the wave amplitudes where a rapid increase in the local ion temperature occurs is then parametrically investigated. It is found that the two threshold wave amplitudes are linearly related and that this dependence translates to a lower required energy density for the onset of heating when compared to the case of a single electrostatic wave. Agreement also is demonstrated between the experimentally observed threshold for stochastic heating and an analytical prediction [B. Jorns and E. Y. Choueiri, Phys. Rev. E 87, 013107 (2013)] for this threshold.
Enantioselective Palladium‐Catalyzed Decarboxylative Allylation of Carbazolones and Indolones: Formal Synthesis of (+)‐Kopsihainanine A (2013)

Characteristics of dislocations at strained heteroepitaxial InGaAs/GaAs interfaces (1989)

The formation, interaction, and propagation of misfit dislocations in molecular-beam epitaxial InGaAs/GaAs heterointerfaces have been studied by transmission electron microscopy. With the lattice mismatch less than 2%, most of the interfacial dislocations are found to be 60° mixed dislocations introduced by glide processes. Sessile edge-type dislocations can also originate from the combination of two 60° mixed dislocations. The ratio of densities of edge dislocations to 60° dislocations was increased during the later part of the elastic strain relaxation. These sessile edge dislocations may be generated in appreciable numbers through a climb process. For large lattice-mismatched systems, the majority of the misfit dislocations are pure edge dislocations and high threading dislocation density is generally found. The interfacial dislocation network is found to contain regions of dislocations with the same Burgers vector that extend over several micrometers. The results support a mechanism that involves misfit dislocation multiplication during the molecular-beam epitaxial growth process.
Reliability of Fixation Preference Testing in Diagnosing Amblyopia (1986)

We evaluated the sensitivity and specificity of standard fixation preference testing and the 10-prism diopter (PD) fixation test in 427 patients. Standard fixation preference testing showed good sensitivity and specificity for than 10 PD. Patients with small angle tropias, however, had a high false-positive rate, with 40% of nonamblyopic patients inappropriately responding with strong fixation preference. The 10-PD fixation test reduced this high false-positive rate and showed only 1.5% false-positive results. Unfortunately, this shift to equal fixation preference was also seen in some patients with amblyopia, as five of 19 patients with three or more lines difference alternated fixation with the 10-PD fixation test. Retesting disclosed that, although these children would briefly alternate to the amblyopic eye while viewing a stationary target, they would not hold fixation with the amblyopic eye through smooth pursuit. Our conclusion is that standard fixation preference testing can be used to diagnose moderate to severe amblyopia in patients with tropias greater than 10 PD. Patients with small angle deviations or straight eyes should be examined with the 10-PD fixation test, with the criterion for equal vision being the ability to hold fixation well with either eye through smooth pursuit.

Predicting Peptide−Receptor, Peptide−Protein, and Chaperone−Protein Binding Using Patterns in Amino Acid Hydrophobic Free Energy Sequences (2000)

Much of the current study of protein organization is aimed at understanding emergent polymeric structure in three rather than one dimensions. This is largely because the weak bonds between amino acid side chains in one-dimensional peptide heteropolymers that determine their equilibrium tertiary structures involve large loop interactions between sequentially distant sites. For this reason, searches for sequential patterns seem intuitively irrelevant even though the coding for 3D protein structure is present in the 1D peptide chain, On the other hand, we have found that there are particular circumstances in which matches in sequential patterns in amino acid side chain thermodynamic properties postdict signatory modularity in the tertiary structure of protein families and polypeptide−protein interactions, such as peptide−receptor, peptide−membrane transporter, nuclear factor−protein docking, and chaperone−protein binding. Here we describe and justify our computational approach to matching sequential organization, with examples from experimentally demonstrable, polypeptide−protein interactions. Using established values for each amino acid's hydrophobic free energy, “hydrophobicity”, in kcal/mol, derived from their normalized free energy of transfer from nonpolar to polar bulk phases of binary solutions,34 we study the variations in hydrophobicity along primary sequences and seek matching patterns among them. We analyze this discrete data series using the all-poles power spectrum for shorter polypeptides. For longer polypeptides and proteins, including membrane receptors, relevant protein domains, nuclear factors, and chaperones, we first decompose the data using autocovariance matrices into orthogonal eigenvectors, compose these eigenvectors with the original series to generate eigenfunctions, and then compute their power spectra. We show examples of sequential pattern-matched peptides that postdict binding of a non-peptide (estrogen) receptor, protein (calcineurin) binding to its T-cell nuclear factor (NFAT) docking site, and chaperone (GroEL) binding to one of its target enzyme proteins (β-lactamase). Polypeptide sequences and the associated proteins that bind them share distinguishing spectral features in their all poles power spectrum. This approach achieves practical significance because inversion of these analytic methods are now being used to successfully design de novo peptides which demonstrated their predicted physiological activity.
Depth map distortion analysis for view rendering and depth coding (2009)

Video representations that support view synthesis based on depth maps, such as multiview plus depth (MVD), have been recently proposed, raising interest in efficient tools for depth map coding. In this paper, we derive a new distortion metric that takes into consideration camera parameters and global video characteristics in order to quantify the effect of lossy coding of depth maps on synthesized view quality. In addition, a new skip mode selection method is proposed based on local video characteristics. Experimental results with the proposed mode selection scheme show coding gains of up to 2 dB for the synthesized views, as well as better subjective quality.
Outcome of epidural blood patch for imaging-negative spontaneous intracranial hypotension (2023)

Given the high responder rates of epidural blood patch in our study, empirical epidural blood patch should be considered to treat new-onset orthostatic headache, even when brain and spinal imaging are negative. The necessity of lumbar puncture is questionable considering the high response rate of epidural blood patch and low rate of "low pressure."
AGAMOUS‐LIKE 6 is a floral promoter that negatively regulates the FLC/MAF clade genes and positively regulates FT in Arabidopsis (2010)

MADS-box genes encode a family of transcription factors that regulate diverse developmental programs in plants. The present work shows the regulation of flowering time by AGL6 through control of the transcription of both a subset of the FLOWERING LOCUS C (FLC) family genes and FT, two key regulators of flowering time. The agl6-1D mutant, in which AGL6 was activated by the 35S enhancer, showed an early flowering phenotype under both LD and SD conditions. Its early flowering was additively accelerated by CONSTANS (CO) overexpression. The agl6-1D mutation strongly suppressed the late flowering of fve-4 and fca-9 mutants. Endogenous AGL6 transcript accumulation was photoperiod-independent and the AGL6:GFP protein was preferentially localized in the nucleus. In agl6-1D plants, the expression of FLC, MADS AFFECTING FLOWERING (MAF) 4, and MAF5 was downregulated. Interestingly, late flowering of a functional FRIGIDA (FRI) FLC allele was dramatically suppressed by the agl6-1D mutation. AGL6 activation in the flc-3 background further enhanced FT expression, suggesting that AGL6 also regulates FT expression independently of FLC mRNA level. A near RNA-null ft-10 mutation completely suppressed early flowering of the agl6-1D plants, suggesting that FT is a major downstream output of AGL6. Transgenic plants overexpressing an artificial microRNA targeting AGL6 showed a late-flowering phenotype. In these plants, FT expression was downregulated, whereas FLC expression was upregulated. The present results suggest that AGL6 acts as a floral promoter with a dual role, the inhibition of the transcription of the FLC/MAF genes and the promotion of FT expression in Arabidopsis.
Application of controller area network to mobile robots (2002)

A mobile robot hardware architecture generally consists of a number of sensors and actuators connected to a central processing unit. This type of architecture is time consuming and leads to an unreliable system. The purpose of this paper is to present a decentralized architecture made possible by recent advances in electronics. This architecture is based on the controller area network (CAN) bus and is shown to be very suitable and advantageous in mobile robotics.
Elastic Documents: Coupling Text and Tables through Contextual Visualizations for Enhanced Document Reading (2018)

Today's data-rich documents are often complex datasets in themselves, consisting of information in different formats such as text, figures, and data tables. These additional media augment the textual narrative in the document. However, the static layout of a traditional for-print document often impedes deep understanding of its content because of the need to navigate to access content scattered throughout the text. In this paper, we seek to facilitate enhanced comprehension of such documents through a contextual visualization technique that couples text content with data tables contained in the document. We parse the text content and data tables, cross-link the components using a keyword-based matching algorithm, and generate on-demand visualizations based on the reader's current focus within a document. We evaluate this technique in a user study comparing our approach to a traditional reading experience. Results from our study show that (1) participants comprehend the content better with tighter coupling of text and data, (2) the contextual visualizations enable participants to develop better summaries that capture the main data-rich insights within the document, and (3) overall, our method enables participants to develop a more detailed understanding of the document content.
Aptamer Chimeras for Therapeutic Delivery: The Challenging Perspectives (2018)

Nucleic acid-based aptamers have emerged as efficient delivery carriers of therapeutics. Thanks to their unique features, they can be, to date, considered one of the best targeting moieties, allowing the specific recognition of diseased cells and avoiding unwanted off-target effects on healthy tissues. In this review, we revise the most recent contributes on bispecific and multifunctional aptamer therapeutic chimeras. We will discuss key examples of aptamer-mediated delivery of nucleic acid and peptide-based therapeutics underlying their great potentiality and versatility. Achieved objectives and challenges will be highlighted as well.

Defective homologous recombination in platinum based chemotherapy for gastric cancer. (2018)

e16068 Background: Defective homologous recombination (HR) due to genetic aberrations of HR genes contributes to a high response of platinum therapy in ovarian and breast cancers. The aim of this study is to clarify the clinical significance of defective HR in platinum based chemotherapy for gastric cancer (GC). Methods: A total of 26 patients (21 men and 5 women, with a median age of 66 years) who underwent platinum based chemotherapy for unresectable metastatic GC were enrolled in this retrospective study. Metastatic sites after gastrectomy were lymph node in 9 (35%), liver in 9 (33%), peritoneum in 8 (30%), others in 2 (7%) patients. Genetic aberrations of HR genes (BRCA1, BRCA2, RAD50, RAD51C, RAD51D, PALB2 and FANCD2) in the primary tumor were assessed by cancer gene-panel. We evaluated the association between defective HR and treatment response (RECIST ver. 1.1), progression free survival (PFS) and overall survival (OS). Results: BRCA1, BRCA2, RAD50, PALB2, and FANCD2 mutations were shown in 3 (11%), 1 (4%), 1 (4%), 1 (4%) and 1 patient (4%), respectively. Overall, 5 patients (19%) had genetic aberrations of HR genes (defective HR group). Objective response rate (complete or partial response) was 50% in the defective HR group and 25% in the proficient HR group (P = 0.55). Disease control rate (complete or partial response or stable disease) was 100% in the defective HR group and 50% in the proficient HR group (P = 0.12). Median PFS was 10 months (95% CI, 3.76–16.24) in the defective HR group and 3 months (1.73–4.27) in the proficient HR group (P = 0.042). Median OS was 17 months (15.04–18.96) in the defective HR group and 8 months (3.88–12.13) in the proficient HR group (P = 0.058). Conclusions: Genetic aberration ofHR genes was significantly associated with a high response of platinum based chemotherapy and favorable patient outcome in unresectable metastatic GC. Clinical utility of the assessment of defective HR as a predictive or prognostic indicator for unresectable metastatic GC is worth considering further large-scale studies.
Investigation of Underperformance in Fielded N-type Monocrystalline Silicon Photovoltaic Modules (2022)

As photovoltaic (PV) modules continue to evolve, it is important to catch and understand the causes behind new failure modes. Herein, we study n-type monocrystalline silicon PV modules that have been fielded at a utility scale power plant for 5 years, all of which have already degraded to < 90% of the nameplate max power (Pmp). High resolution electroluminescence (EL) and photoluminescence (PL) imaging suggests multiple possible factors contributing to the modules' underperformance, including series resistance issues (Rs) and wafer non-uniformities. Dark lock-in thermography (DLIT) measurements on a selected module suggests two specific module strings have high Rs. We then tabbed out all 60 cells of the same module. Suns-Voc measurements confirm relatively higher Rs values for the cells in these two strings. Multi-irradiance IV scans show the largest underperformance at the cell level for these same cells. This implicates Rs, rather than wafer non-uniformity, to be the largest contributor to the cell and therefore module underperformance.
Development of a multi-terminal crimp package for smart textile integration (2012)

Goal of this work is the development of a new package to be integrated into large-area smart textiles. The benefits of the well-known crimp technology are transferred to a new field. The so-called Crimp Flat Pack (CFP) is a lead-frame based electronic package that features crimp terminals instead of standard leads. The module can be directly attached to different types of substrates, in particular to fabric circuits. Its size and complexity can reach from a simple two-terminal package to larger multi-terminal devices. The standard sized module has a circuit board area of 2 cm × 2 cm and 10 crimp terminals. Eight of them are used for the communication between other modules and for mechanical attachment. Two terminals are used to attach a sensor that collects data inside the fabric. Mainly two tools were developed for the process. At first, a forming tool that bends the contact pins upwards and brings the crimp barrels into shape as well as the actual crimping tool that allows parallel crimping. On the system's side of view the module carries a simple micro-controller and passives. Communication between neighboring modules is done via I <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ;C-protocol. Measurement of sensor date inside the fabric can be realized. The new package opens opportunities to the manufacturing of smart textiles as it uses standard manufacturing technologies as well as a robust, low-cost, and low-temperature interconnection technology.
Strong Scaling of Matrix Multiplication Algorithms and Memory-Independent Communication Lower Bounds (2012)

A parallel algorithm has perfect strong scaling if its running time on P processors is linear in 1/P, including all communication costs. Distributed-memory parallel algorithms for matrix multiplication with perfect strong scaling have only recently been found. One is based on classical matrix multiplication (Solomonik and Demmel, 2011), and one is based on Strassen's fast matrix multiplication (Ballard, Demmel, Holtz, Lipshitz, and Schwartz, 2012). Both algorithms scale perfectly, but only up to some number of processors where the inter-processor communication no longer scales. We obtain a memory-independent communication cost lower bound on classical and Strassen-based distributed-memory matrix multiplication algorithms. These bounds imply that no classical or Strassen-based parallel matrix multiplication algorithm can strongly scale perfectly beyond the ranges already attained by the two parallel algorithms mentioned above. The memory-independent bounds and the strong scaling bounds generalize to other algorithms.
