Membranes based on poly(vinyl alcohol)/β-cyclodextrin blends (2010)

Membranes based on poly(vinyl alcohol)/β-cyclodextrin (PVA/β-CD) with various compositions have been prepared by using a series of three freezing/thawing cycles. The membranes were studied with scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and also water swelling tests as well as contact angle measurements have been performed. The swelling kinetics of membranes in water at different temperatures have been also evaluated. It was established that the membrane properties are influenced by the β-cyclodextrin (β-CD) content and the pores diameter. The crystalline fraction in PVA/β-CD membranes increases with the increase of β-CD content.

Robust recognition of faces and facial features with a multi-modal system (2002)

We use a combination of shape and texture analysis, color segmentation and motion information for finding the positions of whole faces plus the precise location and shape of the mouth. Combining several modalities improves the robustness of the analysis considerably and allows handling of a wide variety of conditions. Mouth shapes can enhance the accuracy of speech recognition systems, in particular under noisy conditions. However, finding the shape of the mouth precisely under unrestricted conditions is a challenging task. To be of practical value a system must handle different complexions of people as well as variations in lighting, different head orientations, moustaches, beards, and glasses. To deal with such a diversity of conditions, our system includes several different models of the face and the mouth area. New faces are compared to these models and the most representative one is chosen for the analysis. We tested our system on samples from video sequences of 50 different speakers. When trained on a particular person, the mouth location is found correctly in more than 98% of the images. When trained on a random set of 10 people from the database, the system handles typically 87% of the other people correctly. In speaker-dependent lip reading experiments we observed 93% word accuracy on five-digit strings.
ULTRASONIC SPECTROSCOPY IN CROSS-PLY FIBER REINFORCED COMPOSITES APPLIED TO DISPERSION EFFECTS CHARACTERIZATION OF ELASTIC SHEAR WAVE (1990)

The theoretical and experimental studies of the dispersion effects, for the propagation of elastic shear waves, in two cross-ply fiber reinforced composites are presented. They exhibit, in the long wavelength limit, a fourfold and an eightfold axis of rotation, respectively. When the elastic wavelength becomes comparable to the composite period, spatial dispersion effects are expected : departure from the linearity of the curves, stop bands and, in the eigthfold axis material, an acoustical activity induced by the helical stacking of the elementary layers.
Pericyte-Based Human Tissue Engineered Vascular Grafts: In Vivo Feasibility Assessment (2010)

Although autologous vessel grafts are the gold standard for bypass procedures, they are limited by availability in many cases. Current synthetic grafts are not suitable for small-diameter (ID&lt;6mm) vascular applications due to acute thrombosis. While a tissue-engineered vascular graft (TEVG), constructed by incorporating cells within a biodegradable scaffold, seems to be a possible solution to the challenge, its success greatly relies on an appropriate cell source and an efficient cellular delivery and carrier system. Terminally-differentiated vascular cells have poor self-renewal and expansion capabilities, exhibit phenotype switching in culture, and are difficult to harvest in necessary numbers, all of which represent limitations of their use in tissue engineering. Human adult mesenchymal stem cells (MSCs) exhibit multipotentiality and self-renewal capabilities, are more readily available, and therefore could overcome these limitations [1]. Pericytes closely encircle endothelial cells in capillaries. It has been shown that pericytes purified from multiple tissue types displayed multipotentiality, suggesting that they are developmental precursors of MSC [2].
Exosomes released by metabotropic glutamate receptor 1 (GRM1) expressing melanoma cells increase cell migration and invasiveness (2017)

Exosomes are naturally occurring membrane-bound nanovesicles generated constitutively and released by various cell types, and often in higher quantities by tumor cells. Exosomes may facilitate communication between the primary tumor and its local microenvironment, supporting cell invasion and other early events in metastasis. A neuronal receptor, metabotropic glutamate receptor 1 (GRM1), when ectopically expressed in melanocytes, induces <i>in vitro</i> melanocytic transformation and spontaneous malignant melanoma development <i>in vivo</i> in a transgenic mouse model. Our earlier studies showed that genetic modulation in GRM1 expression by siRNA or disruption of GRM1-mediated glutamate signaling interfere with downstream effectors resulting in a decrease in both cell proliferation <i>in vitro</i> and tumor progression <i>in vivo</i>. In this study, we sought to determine whether exosome formation might play a role in GRM1 mediated melanoma development and progression. To test this, we utilized <i>in vitro</i> cultured cells in which GRM1 expression and function could be modulated by pharmacological and genetic means and determined effects on exosome production. We also tested the effects of exosomes from GRM1 expressing melanoma cells on growth, migration and invasion of GRM1 negative cells. Our results show that although GRM1 expression has no influence on exosome quantity, exosomes produced by GRM1-positive cells modulate the ability of the recipient cell to migrate, invade and exhibit anchorage-independent cell growth.
Stabilized Ru[(H2O)6]3+ in Confined Spaces (MOFs and Zeolites) Catalyzes the Imination of Primary Alcohols under Atmospheric Conditions with Wide Scope (2018)

Imines are ubiquitous intermediates in organic synthesis, and the metal–mediated imination of alcohols is one of the most direct and simple methods for their synthesis. However, reported protocols lack compatibility with many other functional groups since basic supports/media, pure oxygen atmospheres, and/or released hydrogen gas are required during reaction. Here we show that, in contrast to previous metal-catalyzed methods, hexa-aqueous Ru(III) catalyzes the imination of primary alcohols with very wide functional group tolerance, at slightly acid pH and under low oxygen atmospheres. The inorganic metal complex can be supported and stabilized, integrally, within either faujasite-type zeolites (Y and X) or a metal organic framework (MOF), to give a reusable heterogeneous catalyst which provides an industrially viable process well below the flammability limit of alcohols and amines.
Efficient wave type fingerprinting and filtering by six-component polarization analysis (2023)

SUMMARY We present a technique to automatically classify the wave type of seismic phases that are recorded on a single six-component recording station (measuring both three components of translational and rotational ground motion) at the Earth’s surface. We make use of the fact that each wave type leaves a unique ’fingerprint’ in the six-component motion of the sensor (i.e. the motion is unique for each wave type). This fingerprint can be extracted by performing an eigenanalysis of the data covariance matrix, similar to conventional three-component polarization analysis. To assign a wave type to the fingerprint extracted from the data, we compare it to analytically derived six-component polarization models that are valid for pure-state plane wave arrivals. For efficient classification, we make use of the supervised machine learning method of support vector machines that is trained using data-independent, analytically derived six-component polarization models. This enables the rapid classification of seismic phases in a fully automated fashion, even for large data volumes, such as encountered in land-seismic exploration or ambient noise seismology. Once the wave-type is known, additional wave parameters (velocity, directionality and ellipticity) can be directly extracted from the six-component polarization states without the need to resort to expensive optimization algorithms. We illustrate the benefits of our approach on various real and synthetic data examples for applications such as automated phase picking, aliased ground-roll suppression in land-seismic exploration and the rapid close-to real-time extraction of surface wave dispersion curves from single-station recordings of ambient noise. Additionally, we argue that an initial step of wave type classification is necessary in order to successfully apply the common technique of extracting phase velocities from combined measurements of rotational and translational motion.
Execution patterns in object-oriented visualization (1998)

Execution patterns are a new metaphor for visualizing execution traces of object-oriented programs. We present an execution pattern view that lets a programmer visualize and explore a program&amp;apos;s execution at varied levels of abstraction. The view employs visual, navigational, and analytical techniques that accommodate lengthy, real-world traces. By classifying repetitive behavior automatically into high-order execution patterns, we drastically reduce the information a programmer must assimilate, with little loss of insight.
Minimal Knowledge vs the Real World (2002)

In this paper we show that Viggiano’s Minimal Knowledge assumption can be used for color correction when the illumination is known.Indeed,given a known illuminant we find that real data is well modelled by the Minimal Knowledge assumption.Experiments demonstrate that color correction based on the Minimal Knowledge assumption is similar to that based on real data.
Immunochemical comparison of transformation‐associated protein and secreted phosphoprotein (1990)

Transformation-associated protein (TAP) has been detected in MSV-M-transformed rat cell lines as glycosylated, weakly phosphorylated protein of molecular weight (Mr) 66,000 and 68,000. In the ts-MSV-M-transformed rat kidney cell line (6m2), the synthesis of TAP and the v-mos gene product is temperature-sensitive and accompanies the expression of transformation phenotypes. Therefore, TAP potentially plays a role in cellular transformation. On the other hand, SPP represents a family of glycosylated phosphoprotein with apparent Mr ranging from 42,000 to 69,000. SPP has been detected in osteoblasts and in avian and murine retrovirus-transformed rat and mouse epithelial cells. Therefore, the potential relatedness of TAP and SPP was studied. Using the 6m2 cells, we found that SPP was strongly phosphorylated and was synthesized at both the permissive (33 degrees C) and non-permissive (39 degrees C) temperatures. By contrast, TAP was weakly phosphorylated, and was synthesized, as we found previously, only at the permissive temperature of 33 degrees C. Furthermore, in 35S-methionine incorporation studies, TAP became heavily labelled whereas SPP was not (consistent with its amino acid composition having few methionine residues). Using 125I-TAP in both immunoprecipitation and radioimmunoassays, it was found that an antiserum raised against SPP did not cross-react with 125I-TAP. Additionally, SPP has now been found in many human and rodent cells, while TAP thus far has only been detected in MSV-transformed rat cells. These data suggest that structurally, TAP and SPP are not closely related phosphoproteins.
Shape‐Dependent Optoelectronic Cell Lysis (2014)

We show an electrical method to break open living cells amongst a population of different cell types, where cell selection is based upon their shape. We implement the technique on an optoelectronic platform, where light, focused onto a semiconductor surface from a video projector creates a reconfigurable pattern of electrodes. One can choose the area of cells to be lysed in real-time, from single cells to large areas, simply by redrawing the projected pattern. We show that the method, based on the "electrical shadow" that the cell casts, allows the detection of rare cell types in blood (including sleeping sickness parasites), and has the potential to enable single cell studies for advanced molecular diagnostics, as well as wider applications in analytical chemistry.

Shorter Quasi-Adaptive NIZK Proofs for Linear Subspaces. (2013)

We define a novel notion of quasi-adaptive non-interactive zero knowledge (NIZK) proofs for probability distributions on parametrized languages. It is quasi-adaptive in the sense that the common reference string (CRS) generator can generate the CRS depending on the parameters defining the language. However, the simulation is required to be uniform, i.e., a single efficient simulator should work for the whole class of parametrized languages. For distributions on languages that are linear subspaces of vector spaces over bilinear groups, we give quasi-adaptive NIZKs that are shorter and more efficient than Groth-Sahai NIZKs. For many cryptographic applications quasi-adaptiveNIZKs suffice, and our constructionscan lead to significant improvements in the standard model. Our construction can be based on any k-linear assumption, and in particular under the Symmetric eXternal Diffie Hellman (SXDH) assumption our proofs are even competitive with Random-Oracle based Σ-protocol NIZK proofs. We also show that our system can be extended to include integer tags in the defining equations, where the tags are provided adaptively by the adversary. This leads to applicability of our system to many applications that use tags, e.g. applications using Cramer-Shoup projective

Dynamic high energy density plasma environments at the National Ignition Facility for nuclear science research (2017)

We present the generation of dynamic high energy density plasmas in the pico- to nano-second time domain at high-energy laser facilities affords unprecedented nuclear science research possibilities. At the National Ignition Facility (NIF), the primary goal of inertial confinement fusion research has led to the synergistic development of a unique high brightness neutron source, sophisticated nuclear diagnostic instrumentation, and versatile experimental platforms. These novel experimental capabilities provide a new path to investigate nuclear processes and structural effects in the time, mass and energy density domains relevant to astrophysical phenomena in a unique terrestrial environment. Some immediate applications include neutron capture cross-section evaluation, fission fragment production, and ion energy loss measurement in electron-degenerate plasmas. More generally, the NIF conditions provide a singular environment to investigate the interplay of atomic and nuclear processes such as plasma screening effects upon thermonuclear reactivity. Lastly, achieving enhanced understanding of many of these effects will also significantly advance fusion energy research and challenge existing theoretical models.

C/EBP Bypasses Granulocyte Colony-Stimulating Factor Signals to Rapidly Induce PU.1 Gene Expression, Stimulate Granulocytic Differentiation, and Limit Proliferation in 32D cl3 Myeloblasts (1999)

Within hematopoiesis, C/EBPalpha is expressed only in myeloid cells, and PU.1 is expressed mainly in myeloid and B-lymphoid cells. C/EBPalpha-deficient mice lack the neutrophil lineage and retain monocytes, whereas PU.1-deficient mice lack monocytes and have severely reduced neutrophils. We expressed a C/EBPalpha-estrogen receptor ligand-binding domain fusion protein, C/EBPalphaWT-ER, in 32D cl3 myeloblasts. 32D cl3 cells proliferate in interleukin-3 (IL-3) and differentiate to neutrophils in granulocyte colony-stimulating factor (G-CSF). In the presence of estradiol, C/EBPalphaWT-ER induced morphologic differentiation and the expression of the myeloperoxidase, lactoferrin, and G-CSF receptor mRNAs. C/EBPalphaWT-ER also induced a G1/S cell cycle block, with induction of p27 and Rb hypophosphorylation. bcr-ablp210 prevented 32D cl3 cell differentiation. Activation of C/EBPalpha-ER in 32D-bcr-ablp210 or Ba/F3 B-lymphoid cells induced cell cycle arrest independent of terminal differentiation. C/EBPalphaWT-ER induced endogenous PU.1 mRNA within 8 hours in both 32D cl3 and Ba/F3 cells, even in the presence of cycloheximide, indicating that C/EBPalpha directly activates the PU.1 gene. However, activation of a PU.1-ER fusion protein in 32D cl3 cells induced myeloperoxidase (MPO) RNA but not terminal differentiation. Thus, C/EBPalpha acts downstream of G-CSF and upstream of PU.1, p27, and potentially other factors to induce myeloblasts to undergo granulocytic differentiation and cell cycle arrest.

POS-328 THE BURDEN OF HYPERKALEMIA IN PATIENTS WITH CHRONIC KIDNEY DISEASE: A REPORT FROM THE DISCOVER CKD RETROSPECTIVE COHORT (2021)

Hyperkalemia (HK), defined as serum potassium (sK+) >5.0 mmol/L, is a potentially fatal condition most often observed in patients with chronic kidney disease (CKD), heart failure (HF) or diabetes and exacerbated by medications that inhibit the renin-angiotensin aldosterone system (RAASi). This real-world study describes characteristics of patients with and without HK in a large international observational study of patients with CKD.
