Robotic tactile sensor array fabricated from a piezoelectric polyvinylidene fluoride film (2002)

A robotic tactile sensor comprised of 25 discrete sensor electrodes arranged in a 5*5 grid was designed and fabricated from a piezoelectric polyvinylidene fluoride (PVDF) film coupled to an integrated circuit (IC). Each of the 25 sensing electrodes in the IC grid were connected to metal-oxide-semiconductor field effect transistor (MOSFET) amplifiers which provided sufficient gain to generate usable response signal levels. Sensors fabricated from varying thicknesses of PVDF film are evaluated. The sensor based on the 25- mu m-thick PVDF film was considered to be the optimal sensor configuration, based on its bias-time performance and its linear response over the loading range tested (0/8 to 76.0 grams). There was no detectable coupling between the nearest-neighbor sensing elements in any of the sensor configurations. As a demonstration, the optimal sensor configuration is used to recognize a toroidal-shaped load.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The theories of oscillating-vane and rotating-disk pressure gauges (1970)

This paper considers the theories of gas damping of vane and disk gauges by assuming diffusive reflection of gas molecules off solid surfaces. An equation is derived for the oscillating-vane gauge which takes account of the periodic variation in the gas density, and of the damping due to the effective areas both parallel and normal to the vane velocity. For the rotating-disk gauge an equation is derived for the drag on the free disk due to diffusion, slip and viscosity of the gas.
Silicon-29 NMR Studies of Tetraalkylammonium Silicate Solutions. 1. Equilibria,<sup>29</sup>Si Chemical Shifts, and<sup>29</sup>Si Relaxation (1998)

The addition of tetraalkylammonium cations to aqueous silicate solutions enhances the abundance of symmetric, cagelike, polysilicate anions including the cubic octamer, Si(8)O(20)(8)(-). The equilibrium ratio of tetramethylammonium (TMA) cations to the octameric silicate anion is 8:1 for solutions with a concentration ratio [OH(-)]:[Si] >/= 1:1. Evidence indicates that organocations directly associate with cagelike polyanions to form a protective shell of hydrophobic hydration that impedes hydrolysis of the central anion.
Sound-Word2Vec: Learning Word Representations Grounded in Sounds (2017)

To be able to interact better with humans, it is crucial for machines to understand sound -a primary modality of human perception. Previous works have used sound to learn embeddings for improved generic semantic similarity assessment. In this work, we treat sound as a first-class citizen, studying downstream 6textual tasks which require aural grounding. To this end, we propose sound-word2vec -a new embedding scheme that learns specialized word embeddings grounded in sounds. For example, we learn that two seemingly (semantically) unrelated concepts, like leaves and paper are similar due to the similar rustling sounds they make. Our embeddings prove useful in textual tasks requiring aural reasoning like text-based sound retrieval and discovering Foley sound effects (used in movies). Moreover, our embedding space captures interesting dependencies between words and onomatopoeia and outperforms prior work on aurallyrelevant word relatedness datasets such as AMEN and ASLex.
Efficient large-scale purification of restriction fragments by solute-displacement ion-exchange HPLC (1993)

Extreme overloading of HPLC columns with sample can create a condition of binding site saturation causing competition and displacement among solutes during column elution. This has been termed solute-displacement chromatography (SD-HPLC). We present an example of this phenomenon for the preparative fractionation and purification of restriction fragments of almost identical size (1337 and 1388 bp) which cannot be resolved by agarose gel electrophoresis. Standard analytical ion-exchange HPLC chromatography failed to separate these fragments from each other and from an unexpectedly early eluting pUC-derived vector fragment of 2.7 kbp. We demonstrate that by intentional overloading of the small (4.6 x 35 mm) non-porous TSK-DEAE HPLC column, hundreds of micrograms of DNA restriction fragments could be resolved and purified in a single HPLC run of less than 30 minutes.
Association of the 323/A3 surface glycoprotein with tumor characteristics and behavior in human breast cancer. (1990)

We have earlier described a monoclonal antibody (323/A3) against a Mr 43,000 surface glycoprotein of MCF-7 human breast cancer cells which shows considerable specificity for primary and metastatic breast tumors (Cancer Res., 46: 1306-1317, 1986). Here we report the occurrence of the 323/A3 antigen in a large cohort of primary breast tumors (m = 384) and its interrelationship with several clinically important variables. Frozen, stored tumor tissues were examined by a Western blot procedure, and the level of 323/A3 protein in individual tumors was calculated in arbitrary units based on the integrated Mr 43,000 signal in tumors compared with an MCF-7 internal standard. Thirty-six % (139 of 384) of tumors were found to be positive for 323/A3. Higher frequencies of 323/A3 protein were found in tumors larger than 2 cm (P = 0.03), tumors with infiltrated lymph nodes (P = 0.01), and tumors without estrogen receptor (P = 0.006). No significant relationship was found with patient age, menopausal status, or progesterone receptor status. Of the newer clinical determinants proliferative rate (% S phase), DNA ploidy, and the lysosomal protease cathepsin D, but not the HER-2/neu oncogene protein, were significantly correlated with 323/A3. The presence of 323/A3 protein was also related to increased recurrence (P = 0.003) and mortality (P = 0.036) after primary treatment. As an exposed surface antigen, this glycoprotein might be a useful target in radioimaging and immunotherapy of some human breast tumors, especially those having large size, infiltrated lymph nodes, deficient estrogen receptor, high proliferative rate, abnormal DNA content, and high levels of cathepsin D, all of which are ominous indicators of tumor behavior.
Iron-Catalyzed Reductive Cyclization of 1,6-Enynes (2013)

A precatalyst of FeCl2 and iminopyridine was activated in situ by a combination of diethylzinc and magnesium bromide etherate; it catalyzed the reductive cyclization of 1,6-enynes to give pyrrolidine and tetrahydrofuran derivatives from N- and O-tethered 1,6-enynes. The scope of the transformation was explored.

Overexpression, Purification, and Immunogenicity of Recombinant Porin Proteins of Salmonella enterica Serovar Typhi (S. Typhi) (2009)

Porin proteins of Gram-negative bacteria are outer membrane proteins that act as receptors for bacteriophages and are involved in a variety of functions like solute transport, pathogenesis, and immunity. Salmonella enterica serovar Typhi (S. Typhi), a Gram-negative bacterium, is the causative agent of typhoid fever. Porins of S. Typhi have been shown to have a potential role in diagnostics and vaccination. In the present study, the major outer membrane proteins OmpF and OmpC from S. Typhi were cloned in pQE30UA vector and expressed in E. coli. The immunogenic nature of the recombinant porin proteins were evaluated by ELISA by raising hyperimmune sera in Swiss Albino mice with three different adjuvants (i.e., Freund's adjuvant and two human-compatible adjuvants like montanide and aluminium hydroxide gel) and proved to be immunogenic. The recombinant OmpF and OmpC generated in this work may be used for further studies for vaccination and diagnostics.
Zinc Catalyzed and Mediated Propargylations with Propargyl Boronates (2009)

The utility of allenyl and propargyl boronates for the propargylation of aldehydes and ketones mediated by zinc is presented. The reaction is catalytic in zinc with allenyl or propargyl borolanes. The propargylation with crystalline and air-stable propargyl diethanolamine boronates was also achieved. A catalytic cycle is proposed, and preliminary mechanistic studies are discussed.
A priority TCAM IP-routing lookup scheme (2003)

A priority TCAM IP-routing lookup scheme, which combines a priority ternary content addressable memory (TCAM) technique with a compact IP-routing lookup scheme, is proposed in this paper. It not only completes an IP-routing lookup with two memory accesses but also achieves small lookup table size and fast table reconstruction time.
Modulation-Format-Independent Wavelength Conversion (2009)

Role of the L3T4-antigen in T cell activation. II. Inhibition of T cell activation by monoclonal anti-L3T4 antibodies in the absence of accessory cells. (1985)

We have used two monoclonal antibodies (Mab) to the L3T4 antigen to reexplore the role of this molecule in the process of T cell activation. Both Mab (Gk1.5 and 2B6) were capable of inhibiting Con A-induced IL 2 production by a number of antigen-specific T cell hybridomas in an assay system that was free of major histocompatibility complex (MHC) class II antigen-bearing cells. The inhibition produced by the anti-L3T4 Mab was specific, because other Mab to cell surface antigens expressed on the hybridomas were without inhibitory effects. These studies rule out the possibility that the mechanism of inhibition by anti-L3T4 in this model is mediated by blocking interaction of L3T4 with MHC class II products. Taken together, these results and those of other groups of investigators, are most compatible with a dual function for L3T4 in T cell activation. L3T4 might first interact with MHC class II molecules or other molecules on target or accessory cells; L3T4 would subsequently transmit a signal that would regulate the activation process. Mab to L3T4 might exert inhibitory effects at one or both of these steps.
Components of Growth of Income Maintenance Expenditure in Ireland 1951-1979 (1984)

The unidirectional transport of proline by midgut epithelium cells of the tobacco hornworm, Manduca sexta, was investigated in brush border membrane vesicles. Both K.(+)-stimulated and K(+)-insensitive transport pathways were identified. Analyses of K(+)-dependent proline transport revealed 1:1 ratio of K+ to proline, a Km of 13 mM for K+ and a decrease in both Km (from 18 mM to 3 mM) and Vmax (from 37 nmol/mg protein/min to 10 nmol/mg protein/min) for proline in the presence of a K+ gradient. The profiles of cis-inhibition by other amino acids demonstrated that proline is transported into midgut cells by a transport system that is shared by other neutral amino acids.
Characterization of A Polymeric Adsorbed Coating for DNA Microarray Glass Slides (2004)

A new method was developed to covalently attach target molecules onto the surface of glass substrates such as microwell plates, beads, tubes, and microscope slides, for hybridization assays with fluorescent targets. The innovative concept introduced by this work is to physically adsorb onto underivatized glass surfaces a functional copolymer, able to graft amino-modified DNA molecules. The polymer, obtained by radical copolymerization of N,N-dimethylacrylamide, N-acryloyloxysuccinimide, and 3-(trimethoxysilyl)propyl methacrylate, copoly(DMA-NAS-MAPS), self-adsorbs onto the glass surface very quickly, typically in 5-30 min. The film, formed on the surface, bears active esters, which react with amino-modified DNA targets. The surface layer is stable in an aqueous buffer containing various additives (SDS, urea, salt), even at boiling temperature. It should be emphasized that the coating is formed by the immersion of glass slides in a diluted aqueous solution of the polymer. Therefore, the procedure is fast, inexpensive, robust, and reliable, and it does not require time-consuming glass pretreatments. Slides, coated with copoly(DMA-NAS-MAPS), were profitably used as substrates for the preparation of low-density DNA microarrays. The density and the thickness of the films were evaluated by X-ray reflectivity measurements whereas the extent of reaction of functional groups with DNA molecules was determined by a functional test. The experiments indicate that half of the active groups present on the surface reacts with oligonucleotide probes.
<i>Aspergillus fumigatus</i>enhances elastase production in<i>Pseudomonas aeruginosa</i>co-cultures (2015)

In the cystic fibrosis (CF) lung the presence of bacteria and fungi in the airways promotes an inflammatory response causing progressive lung damage, ultimately leading to high rates of morbidity and mortality. We hypothesized that polymicrobial interactions play an important role in promoting airway pathogenesis. We therefore examined the interplay between the most commonly isolated bacterial CF pathogen, Pseudomonas aeruginosa, and the most prevalent filamentous fungi, Aspergillus fumigatus, to test this. Co-culture experiments showed that in the presence of A. fumigatus the production of P. aeruginosa elastase was enhanced. This was confirmed by the presence of zones of clearance on Elastin-Congo Red (ECR) agar, which was identified as elastase by mass spectrometry. When P. aeruginosa were grown in a co-culture model with mature A. fumigatus biofilms, 60% of isolates produced significantly more elastase in the presence of the filamentous fungi than in its absence (P < .05). The expression of lasB also increased when P. aeruginosa isolates PA01 and PA14 were grown in co-culture with A. fumigatus. Supernatants from co-culture experiments were also significantly toxic to a human lung epithelial cell line (19-38% cell cytotoxicity) in comparison to supernatants from P. aeruginosa only cultures (P < .0001). Here we report that P. aeruginosa cytotoxic elastase is enhanced in the presence of the filamentous fungi A. fumigatus, suggesting that this may have a role to play in the damaging pathology associated with the lung tissue in this disease. This indicates that patients who have a co-colonisation with these two organisms may have a poorer prognosis.
Time-dependent pH sensing phenomena using CdSe/ZnS quantum dots in EIS structure (2014)

Time-dependent pH sensing phenomena of the core-shell CdSe/ZnS quantum dot (QD) sensors in EIS (electrolyte insulator semiconductor) structure have been investigated for the first time. The quantum dots are immobilized by chaperonin GroEL protein, which are observed by both atomic force microscope and scanning electron microscope. The diameter of one QD is approximately 6.5 nm. The QDs are not oxidized over a long time and core-shell CdSe/ZnS are confirmed by X-ray photon spectroscopy. The sensors are studied for sensing of hydrogen ions concentration in different buffer solutions at broad pH range of 2 to 12. The QD sensors show improved sensitivity (38 to 55 mV/pH) as compared to bare SiO2 sensor (36 to 23 mV/pH) with time period of 0 to 24 months, owing to the reduction of defects in the QDs. Therefore, the differential sensitivity of the QD sensors with respect to the bare SiO2 sensors is improved from 2 to 32 mV/pH for the time period of 0 to 24 months. After 24 months, the sensitivity of the QD sensors is close to ideal Nernstian response with good linearity of 99.96%. Stability and repeatability of the QD sensors show low drift (10 mV for 10 cycles) as well as small hysteresis characteristics (<10 mV). This QD sensor is very useful for future human disease diagnostics.
Differential heat shock protein localization in chronic lymphocytic leukemia (2009)

Mechanisms behind carcinogenesis and resistance of tumor cells to treatment regimes remain elusive. The major stress proteins Hsp72, Hsp90, and Hsp27 are credible candidates to provide this resistance, as their overexpression in many cancer types is well documented. In addition to being present inside tumor cells, where they confer resistance to apoptosis, Hsp72, in particular, is presented externally, embedded in the cell membrane of cancer cells. This study aimed to investigate the localization of Hsp72, Hsp90, and Hsp27 in leukocytes from patients with CLL and age-matched control subjects. CLL patients were found to express significantly higher levels of iHsp90 (CLL=2463 MFI; control=748 MFI) and iHsp27 (CLL=2190 MFI; control=1031 MFI) in lymphocytes than that expressed by lymphocytes from control subjects. Furthermore, expression of iHsp90 was shown to be related to stage of disease, and expression of iHsp27 correlated with levels of active caspase-3. Patients were found to express very high levels or very low levels of sHsp72 and iHsp72 in CD5(+)/CD19(+) cells, although surface and intracellular datasets did not correlate. Levels of extracellular Hsp72 circulating in the serum were found to correlate with internal levels of Hsp72 and were also found to be significantly lower in patients receiving corticosteroid treatment than in patients not receiving corticosteroid treatment. Finally, analysis of the number of circulating Tregs revealed significantly elevated numbers in CLL patients compared with control subjects.
Nearest-Neighbor Clutter Removal for Estimating Features in Spatial Point Processes (1998)

Abstract We consider the problem of detecting features in spatial point processes in the presence of substantial clutter. One example is the detection of minefields using reconnaissance aircraft images that identify many objects that are not mines. Our solution uses Kth nearest neighbor distances of points in the process to classify them as clutter or otherwise. The observed Kth nearest neighbor distances are modeled as a mixture distribution, the parameters of which are estimated by a simple EM algorithm. This method allows for detection of generally shaped features that need not be path connected. In the minefield example this method yields high detection and low false-positive rates. Another application, to outlining seismic faults, is considered with some success. The method works well in high dimensions. The method can also be used to produce very high-breakdown-point–robust estimators of a covariance matrix.
Purification and subunit structure of deoxyribonucleic acid-dependent ribonucleic acid polymerase II from the mouse plasmacytoma, MOPC 315. (1975)

DNA-dependent RNA polymerase II was purified from the mouse plasmacytoma, MOPC 315.Soluble enzyme was obtained from a nucleoplasmic fraction and subjected to chromatography on phosphocellulose, DEAE-cellulose, and DEAE-Sephadex ion exchange resins and was subjected to sedimentation in sucrose density gradients.A chromatographically homogeneous enzyme was obtained which was purified about 25,000-fold relative to whole cell extracts and which had a specific activity (on native DNA) similar to those reported for other purified eukaryotic class II RNA polymerase preparations.Analysis of purified RNA polymerase II by polyacrylamide gel electrophoresis under nondenaturing conditions revealed three protein bands, designated IIo, II*, and IIB in order of electrophoretic mobility.The subunit compositions of these nondenatured bands were subsequently analyzed by electrophoresis under denaturing conditions.Each enzyme II form contained subunits with molecular weights of 140,000 (IIc), 41,000 (IId), 30,000 (IIe), 25,000 (IIf), 22,000 (IIg), 20,000 (IIh), and 16,000 (Iii).Molar ratios were unity for all subunits except subunit IIh which had a molar ratio of 2. Each enzyme form was distinguished by its highest molecular weight subunit.IIo contained subunit 110 (molecular weight 240,000), II* contained subunit IIa (molecular weight 205,000), and IIB contained subunit IIb (molecular weight 170,000).Total molecular weights for IIo, II*, and IIB were calculated as 554,000, 519,000, and 484,000, respectively.In addition, the number of RNA polymerase II molecules per MOPC 315 tumor cell was calculated to be about 5 x 104. Nucleoplasmic(1, 2) DNA-dependent RNA polymerase II represents one of the three principal classes of eukaryotic RNA
