Genetically marked Rhizobium identifiable as inoculum strain in nodules of soybean plants grown in fields populated with Rhizobium japonicum (1978)

The fate of an inoculum strain of Rhizobium japonicum was studied using a genetically marked strain I-11O subline carrying resistance markers for azide, rifampin, and streptomycin (I-110 ARS). At the time of planting into a field populated with R. japonicum, seeds of soybean cultivars Kent and Peking were inoculated with varying cell densities of strain I-110 ARS. At various times during the growing season, surface-sterilized root nodules were examined for the presence of the inoculum strain by plating onto selective media. The recovery of the inoculum strain was unambiguous, varying, in the case of Kent cultivar, from about 5% with plants (sampled at 51 days) that had been inoculated with 3 X 10(8) cells per cm of row to about 20% with plants (sampled at 90 days) that had been inoculated with 3 X 10(9) cells per cm. The symbiotically incompatible interaction of Peking and strain 110 in Rhizobium-populated field soil was confirmed by the finding that at 60 days after planting, only one nodule in 360 sampled contained strain I-110 ARS. The use of genetically marked Rhizobium bacteria was found to provide for precise identification of the inoculum strain in nodules of field-grown soybeans.
Local Q-linear convergence and finite-time active set identification of ADMM on a class of penalized regression problems (2016)

We study the convergence of the ADMM (Alternating Direction Method of Multipliers) algorithm on a broad range of penalized regression problems including the Lasso, Group-Lasso and Graph-Lasso,(isotropic) TV-L1, Sparse Variation, and others. First, we establish a fixed-point iterationvia a nonlinear operator-which is equivalent to the ADMM iterates. We then show that this nonlinear operator is Fréchet-differentiable almost everywhere and that around each fixed point, Q-linear convergence is guaranteed, provided the spectral radius of the Jacobian of the operator at the fixed point is less than 1 (a classical result on stability). Moreover, this spectral radius is then a rate of convergence for the ADMM algorithm. Also, we show that the support of the split variable can be identified after finitely many iterations. In the anisotropic cases, we show that for sufficiently large values of the tuning parameter, we recover the optimal rates in terms of Friedrichs angles, that have appeared recently in the literature. Empirical results on various problems are also presented and discussed.
Construction of phage display libraries from reactive lymph nodes of breast carcinoma patients and selection for specifically binding human single chain Fv on cell lines. (2004)

The display of recombinant antibody fragments on the surface of filamentous phage mimicks B cells and is therefore a technology ideal to generate antibodies against any potential target antigen in vitro. In order to obtain tumor specific, high-affinity single chain antibody fragments (scFv), it has been speculated that lymph node tissue from cancer patients infiltrated with activated B cells must be a valuable source of antibody V-genes. The aim of this study was to generate a human scFv-phage library from lymph nodes of patients with breast cancer and to develop a stringent depletion and selection protocol in order to isolate specific single chain antibodies recognizing potentially new antigens in breast cancer. The amplification of the V-genes cloned from regional lymph node tissue and their assembly to single chain variable fragments was optimized in terms of library size and diversity. A large set of degenerated primers, annealing to all known V-gene families, was designed and used under optimized PCR conditions. The amplified V-genes were genetically fused in all possible combinations and cloned into a phagemid vector. Depletion and selection on mammary epithelial and primary breast carcinoma cell lines, respectively led to the isolation of a breast cancer cell line specific scFv (BCK-1 scFv) from this patient-derived scFv-phage display library as demonstrated in polyclonal and monoclonal ELISA, using immobilized cell membrane fractions of the indicated cell lines. A new recombinant breast cancer cell line specific antibody based on V-genes derived from reactive B-lymphocyte-infiltrated lymph nodes of patients with breast cancer was isolated via phage display, performing stringent depletion and selection protocols. We believe that this combination of antibody V-gene source and elaborated phage display depletion and selection strategy will be successful for the retrieval of numerous other recombinant, tumor specific antibody fragments.
Controlled radical polymerisation of vinyl monomers catalysed by ruthenium N-heterocyclic carbene complexes (2005)

N-heterocyclic carbene (NHC)-modified ruthenium catalysts of type [RuCl2(p-cymene)(NHC)] (NHC = substituted 2,3-dihydro-1H-imidazol-2-ylidenes: 1,3-Mes2-4,5-Me2, 1,3-Mes2-4,5-H2, 1,3-Mes2-4,5-Cl2, 1,3-Cy2-4,5-Me2, and 1,3-Cy2-4,5-H2; Mes = mesityl, Cy = cyclohexyl) were prepd. beforehand or in situ by combining the [RuCl2(p-cymene)] dimer with the imidazolium salt in presence of a base (e.g., t-BuOK, Cs2CO3, or Al(OiPr)3). The catalysts were then used in homogeneous atom transfer radical polymns. of Me methacrylate and styrene. The polymn. outcome was studied in dependence of catalyst (substitution pattern) and base.

Teaching Students to Focus on the Data in Data Visualization (2015)

Although most technical communication pedagogy provides students with solid advice on how to visualize particular numerical representations, it underproblematizes the rhetorical decisions we make in choosing which numbers to display in the first place. This pedagogical reflection uses Perelman and Olbrechts-Tyteca’s concept of interpretative level to foreground the rhetorical choices that underlie our decisions on how to summarize, aggregate, and synthesize the data we visualize. It then describes two informal classroom activities that emphasize the importance of interpretative level and help students see the recursive nature of data visualization and invention.
Evaluation of Formation Damage/Completion Impairment Following Dynamic Filter-Cake Deposition on Unconsolidated Sand (2008)

Abstract Evaluation of formation and completion (gravel pack and screen only) flow capacity damage in unconsolidated formation material has proven difficult in the laboratory because typical core flood equipment does not adequately confine the formation material to allow drilling and cleanup fluids to be circulated at representative shear rates and pressures over the formation face. A testing protocol and equipment have been developed which allows dynamic flow and fluid loss across unconsolidated formation material at shear rates, temperatures, differential pressures, and times representative of mud circulation rates in the wellbore. The dynamically prepared filtercakes grow to an equilibrium thickness depending on the shear rate, differential pressure, and temperature and are more representative in composition and mass to wellbore filtercakes so that their damage to formation, gravel packs and / or screens can be better evaluated. The effectiveness of cleanup systems can also be determined by circulating the fluids across the mud filtercakes at typical shear rates, differential pressures and temperatures before allowing static soak conditions. At the end of the test, the screen and formation material or screen, gravel pack and formation material are stressed together simulating a wellbore collapse. The permeability of the formation plus gravel pack and screen or formation and screen only are then measured and compared to the initial values to determine flow capacity impairment.

Face Sketch Landmarks Localization in the Wild (2014)

In this letter, we propose a method for facial landmarks localization in face sketch images. As recent approaches and the corresponding datasets are designed for ordinary face photos, the performance of such models drop significantly when they are applied on face sketch images. We first propose a scheme to synthesize face sketches from face photos based on random-forests edge detection and local face region enhancement. Then we jointly train a Cascaded Pose Regression based method for facial landmarks localization for both face photos and sketches. We build an evaluation dataset, called Face Sketches in the Wild (FSW), with 450 face sketch images collected from the Internet and with the manual annotation of 68 facial landmark locations on each face sketch. The proposed multi-modality facial landmark localization method shows competitive performance on both face sketch images (the FSW dataset) and face photo images (the Labeled Face Parts in the Wild dataset), despite the fact that we do not use extra annotation of face sketches for model building.
Degeneracies between symmetric and degenerate pairs of counter-rotating modes in a disk resonator using dielectric plugs (2007)

One means of tuning the symmetric poles or modes, without perturbing the counter-rotating family of poles or modes, of a planar disk resonator with top and bottom electric walls and a magnetic sidewall is to introduce a dielectric plug on its axis. The purpose of this paper is to investigate some intersections between the family of symmetric modes and that of pairs of degenerate counter-rotating modes in such a resonator using a commercial FE solver. The relative dielectric constant of the outer region of the resonator has been restricted to 14.1 while that of the inner region has been allowed to vary between 25 and 500. The paper includes three typical mode charts on this type of resonator as well as some standing wave solutions using an FE solver. The work has application in the design of triple pole circulators and filters. © 2007 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2007.
Death due to a rare complication of colonoscopy and the potential medicolegal implications (2017)

A 64-year-old woman was found dead at home after undergoing a screening colonoscopy. At autopsy, 1.9 L of blood was discovered within her abdominal cavity. The only major abnormality was nontraumatic avulsion of the splenic capsule. This was the only identifiable abnormality capable of causing the severe hemoperitoneum and demise of the patient. Although rare, splenic capsule avulsion is a recognized complication of colonoscopy. Many have theorized that it results from excessive traction on the splenocolic ligament resulting in a tear of the splenic capsule. Most patients present within the first 24 hours after the procedure with nonspecific symptoms, and many patients may not seek medical attention. The paucity of the literature in the area of splenic capsular avulsion after colonoscopy reinforces the importance of reporting known cases, and by doing so raise awareness of this rare but devastating complication of an otherwise beneficial screening procedure.
Variation of Specific Heat with x and y in NaxCoO2-yH2O/D2O (2004)

We report specific heat measurements down to 0.4 K on the layered oxide Na$_x$CoO$_2\cdot\it{y}$H$_2$O/D$_2$O with 0 $\le$ $\it{x}$ $\le$ 0.74 and $\it{y}$ = 0 and 1.4. For the nonhydrated system ($\it{y}$ = 0), the electronic specific heat coefficient $γ_N$ and the Debye temperature $Θ_D$ vary nonmonotonically with $\it{x}$, both displaying minima when $\it{x}$ is close to 0.5. This indicates a systematic change of the electronic and vibrational structures with Na content. For both hydrated and deuterated systems ($\it{x}$ = 0.35 and $\it{y}$ = 1.4), the specific heat reveals a sharp peak with $Δ$C$_p \sim$ 45.5 mJ/mol-K at T$_c^{mid} \sim$ 4.7 K and an anomaly at T$_x \sim$ 0.8 K. While the origin of the later is unknown, the former corresponds to the superconducting transition. Interestingly, the electronic specific heat, after subtracting lattice and Schottky contributions, exhibits roughly T$^2$ behavior between 0.2T$_c$ and T$_c$. This can be explained by assuming an unconventional superconducting symmetry with line nodes. The results obtained under applied magnetic field further support this scenario.

Sticky Projections-A Model-Based Approach to Interactive Shader Lamps Tracking (2015)

Shader lamps can augment physical objects with projected virtual replications using a camera-projector system, provided that the physical and virtual object are well registered to each other. Precise registration and tracking has been a cumbersome and intrusive process in the past. In this paper, we present a new method for tracking complex-shaped physical objects interactively. In contrast to previous approaches our system is mobile and makes solely use of the projection of the virtual replication to track the physical object and "stick" the projection to it. Our method consists of two stages, a fast pose initialization based on structured light patterns and a non-intrusive frame-by-frame tracking based on features detected in the projection. During the tracking phase, a radiometrically corrected virtual camera view based on the current pose prediction is rendered and compared to the captured image. Matched features are triangulated providing a sparse set of surface points that is robustly aligned to the virtual model. The alignment transformation serves as an input for the new pose prediction. Detailed experiments including the evaluation of the overlay accuracy show that our approach can accurately and robustly track complex objects at interactive rates.

Evaluation of Stability, Nature of Modifier, and Short-Term Aging of Modified Binders Using New Tests: LAST, PAT, and Modified RTFO (1998)

In a recent survey of users and producers of modified asphalts, stability and short-term aging were two of the main concerns regarding the use of modified asphalts. In an NCHRP project, a concentrated effort was put into development of revised or new testing procedures to better characterize the nature of modified asphalt and to solve some of the difficulties with using existing aging procedures developed for neat asphalts and modified asphalts. Three main procedures have been proposed to complement the existing Superpave procedures: the laboratory asphalt stability test, for measuring the storage stability of asphalt binders; the particulate additive test, for separation of particulate additives; and the modified rolling thin film oven test for short-term aging. The background behind the development of these test methods is explained, and typical data collected for a number of modified asphalts are presented. The results indicate that these tests show high promise in covering characteristics not covered by the current Superpave binder specifications and in solving some of the problems with the existing aging methods. The results also indicate that the behavior of modified binder can be very complex and that the method of data interpretation is very critical.

Involvement of transcription factor <scp>E</scp>ts‐1 in the expression of the α3 integrin subunit gene (2012)

The α3β1 integrin is an adhesion receptor for extracellular matrix proteins, and plays crucial roles in cell motility, proliferation, and differentiation. The aberrant expression of this adhesion molecule on tumor cells is frequently associated with their malignant behaviors. We previously reported that the Ets transcription factor-binding consensus sequence 133 bp upstream of the mouse α3 integrin gene is an important element for its expression in various tumor cell lines. In the present study, we attempted to identify a transcription factor bound to the Ets-consensus sequence, and found that Ets-1 bound to this sequence in an electrophoretic mobility shift assay, chromatin immunoprecipitation assay, and pull-down assay with a tandem repeat of the sequence as adsorbent. We next examined the role of Ets-1 in α3 integrin gene expression by use of a luciferase assay with a reporter plasmid containing the 5'-flanking region of the α3 integrin gene. Cotransfection of HEK293T cells with an Ets-1 expression construct and the reporter plasmid increased luciferase activity. By contrast, transfection of HT1080 cells (high α3 integrin expresser) with a dominant-negative mutant of Ets-1 decreased luciferase activity. Overexpression of Ets-1 in HepG2 hepatocellular carcinoma cells (low α3 integrin expresser) upregulated α3 integrin expression as assessed by immunoprecipitation. Finally, the induction of α3 integrin gene expression in HepG2 cells after transforming growth factor-β1 treatment was abrogated by the dominant-negative mutant of Ets-1. These results suggest that Ets-1 is involved in transcriptional activation of the α3 integrin gene through its binding to the Ets-consensus sequence at -133 bp.
External Surface Catalytic Sites of Surfactant-Tailored Nanomorphic Zeolites for Benzene Isopropylation to Cumene (2013)

Nanomorphic *BEA, MTW, and *MRE zeolites were investigated as catalysts for isopropylation of benzene. From the deactivation pattern of the zeolites, we evaluated the contribution of external and internal active sites. These nanomorphic zeolites exhibited a high activity and long catalytic lifetime. Such catalytic properties can be explained by a large contribution of external sites, which have the advantage of slow deactivation.
Diffusion in the Lead Chalcogenides. (1972)

Abstract : The dependence on the deviation from stoichiometry of the diffusion coefficients describing interdiffusion (junction diffusion) and self-diffusion (radioactive tracer diffusion) of the constitutent atoms of the lead chalcogenides is obtained for the general case in which diffusion may occur through interstitials, vacancies, and divacancies simultaneously. This model indicates the appropriate experimental conditions for obtaining diffusion data of the two types and provides an explicit framework for interpretation of results and identification of the diffusion mechanisms. It is shown that the parameters characterizing the interdiffusion process may be evaluated independently by an appropriate combination of self-diffusion measurements. Comparisons of this type are made with existing data. (Author)

Activation pattern reproducibility: Measuring the effects of group size and data analysis models (1997)

The reproducibility of patterns from brain activation experiments has been examined only for suprathreshold spatially localized foci. Scatter plots comparing signal levels across all pairs of Talairach voxels for pairs of functional activation images provide an alternative approach for assessing reproducibility. Image-wide, signal-level reproducibility may be quantitatively summarized using pattern similarity measures such as the Pearson product-moment correlation, rho. Empirical population distributions of rho for many pair-wise image comparisons, generated using statistical resampling techniques, may be used to examine the impact of a wide range of experimental variables. We demonstrate the use of such empirical rho-histograms to measure changes in reproducibility for [(15)O]-water PET scans of a simple motor task as a function of group size and data analysis model.
Effective phrase translation extraction from alignment models (2003)

Phrase level translation models are effective in improving translation quality by addressing the problem of local re-ordering across language boundaries. Methods that attempt to fundamentally modify the traditional IBM translation model to incorporate phrases typically do so at a prohibitive computational cost. We present a technique that begins with improved IBM models to create phrase level knowledge sources that effectively represent local as well as global phrasal context. Our method is robust to noisy alignments at both the sentence and corpus level, delivering high quality phrase level translation pairs that contribute to significant improvements in translation quality (as measured by the BLEU metric) over word based lexica as well as a competing alignment based method.
