Characterization of a Class of Soft Bending Arms (2019)

Bending permits soft arms to access a workspace that is not colinear with the initial arm axis; the size and shape of this space depends on the characteristics of the soft arm. Soft bending actuators and arms have developed for specific applications, but not characterized for the general relationship between design variables and performance. This paper defines a class of soft bending arms based on its design, considering the arm as a system constructed from many contracting actuators organized into segments. A modular segment design is presented, and seven variants of this design were constructed and tested for bend radius, bend direction, lateral stiffness and contraction. The variants isolate system parameters, in this case, arm radius and number of actuators within a given segment, to quantify how these parameters affect performance. A trade-off was found between lateral stiffness and bend radius, which can be controlled by altering the arm radius or the number of actuators. Bend direction was found to be coupled to both bend radius and arm load. Finally, a three-segment arm following a bio-inspired design is presented to demonstrate how the experimental results apply to soft robot system design.
A high‐throughput monolithic HPLC method for rapid Vitamin C phenotyping of berry fruit (2006)

A rapid method for the quantification of L-ascorbic acid (1) in berry fruit by HPLC with photodiode array detection is presented. L-Ascorbic acid was resolved on a C18 monolithic column with aqueous buffer, after which the column was washed with acetonitrile to remove lipophilic compounds prior to re-equilibration for analysis of the next sample. Using the monolithic column format with high mobile phase flow rates, the entire separation, wash and re-equilibration were achieved in 3 min. With the exception of gooseberry (Ribes uva-crispa), for which an interfering compound co-eluted, concentrations of 1 could be determined in a wide range of berry fruits after extraction in metaphosphoric acid without further sample preparation. Using this extraction method, recoveries of 1 in excess of 85% were achieved. Fruit or juice extracts were stable in 5% metaphosphoric acid for at least 4 h and stability could be extended to longer than 150 h by the addition of the reducing agent tris(2-carboxethyl)phosphine hydrochloride. Following validation, the method was utilised for the phenotyping of fruit in a Scottish Crop Research Institute (SCRI) Ribes nigrum L. breeding population of 300 individuals. An improved extraction method allowed extraction, quantification of 1 and data analysis to be undertaken in less than one working week.
Graph Types (1992)

Recursive data structures are abstractions of simple records and pointers. They impose a &lt;em&gt; shape&lt;/em&gt; invariant, which is verified at compile-time and exploited to automatically generate code for building, copying, comparing, and traversing values without loss of efficiency. However, such values are always tree shaped, which is a major obstacle to practical use. We propose a notion of &lt;em&gt; graph types &lt;/em&gt;, which allow common shapes, such as doubly-linked lists or threaded trees, to be expressed concisely and efficiently. We define regular languages of &lt;em&gt; routing expressions&lt;/em&gt; to specify relative addresses of extra pointers in a canonical spanning tree. An efficient algorithm for computing such addresses is developed. We employ a second-order monadic logic to decide well-formedness of graph type specifications. This logic can also be used for automated reasoning about pointer structures.
N‐terminal residues of the yeast pheromone receptor, Ste2p, mediate mating events independently of G1‐arrest signaling (2009)

In Saccharomyces cerevisiae, mechanisms modulating the mating steps following cell cycle arrest are not well characterized. However, the N-terminal domain of Ste2p, a G protein-coupled pheromone receptor, was recently proposed to mediate events at this level. Toward deciphering receptor mechanisms associated with this mating functionality, scanning mutagenesis of targeted regions of the N-terminal domain has been completed. Characterization of ste2 yeast overexpressing Ste2p variants indicated that residues Ile 24 and Ile 29 as well as Pro 15 are critical in mediating mating efficiency. This activity was shown to be independent of Ste2p mediated G1 arrest signaling. Further analysis of Ile 24 and Ile 29 highlight the residues' solvent accessibility, as well as the importance of the hydrophobic nature of the sites, and in the case of Ile 24 the specific size and shape of the side chain. Mutation of these Ile's led to arrest of mating after cell contact, but before completion of cell wall degradation. We speculate that these extracellular residues mediate novel receptor interactions with ligand or proteins, leading to stimulation of alternate signaling effector pathways.
Generating text description from content-based annotated image (2012)

This paper proposes a statistical generative model to generate sentences from an annotated picture. The images are segmented into regions (using Graph-based algorithms) and then features are computed over each of these regions. Given a training set of images with annotations, we parse the image to get position information. We use SVM to get the probabilities of combinations between labels and prepositions, obtain the data to text set. We use a standard semantic representation to express the image message. Finally generate sentence from the xml report. In view of landscape pictures, this paper implemented experiments on the dataset we collected and annotated, obtained ideal results.
Characterization of thiol-, aspartyl-, and thiol-metallo-peptidase activities in Madin-Darby canine kidney cells (2000)

We combined fluorogenic substrates or internally quenched fluorescent peptides with specific inhibitors in the pH profile of proteolytic activity experiments in order to detect proteolytic activities in lysates of MDCK cells. Hydrolytic activities related to cathepsin B, L, and D were observed. Serine-proteinase was not detected; however, we clearly demonstrated the presence of a thiol-metallo-endo-oligopeptidase, also called thimet-oligopeptidase (TOP). This peptidase from MDCK cells has substrate and inhibitor specificities as well as an activation profile with mercaptoethanol that are indistinguishable from the recombinant rat testis TOP (EC 3.4.24.15). In addition, polyclonal purified antibodies to this enzyme depleted the TOP activity of MDCK cells in whole homogenate. Although we present only preliminary data, TOP is secreted by MDCK cells. The presence of TOP in a phenotype polarized MDCK cells can have special significance in the cytoplasmic selection, transport, or clearance of short peptides due to restriction of the enzyme to sequences from 6 to 17 amino acids. Therefore, the MDCK cell could be a very useful cellular model with which to study some of the suggested TOP biological functions as processing of biological active peptides and antigen presentation.

Fertilization, including chemotactic phenomena in the Fucaceae (1948)

Abstract Chemotaxis between gametes particularly of the Fucaceae is discussed and techniques for its detection described. Cell-free preparations of Fucus serratus and F. vesiculosus eggs have been obtained which exert a chemotactic attraction on the sperms of F. serratus, F. vesiculosus and F. spiralis, the same chemotactic mechanism among these closely related species being indicated. The chemotactic principle is easily expelled from aqueous solution by a stream of inert gas, and may be recovered in a cooled receiver; it seems therefore to be a simple compound. Various arylacetic acids have a marked effect on the Fucus sperms studied but this effect is distinct from true chemotaxis and is not related to the plant hormone or herbicide activities of the responsible acids.

Defined Sequence Modules and an Architectural Element Cooperate To Promote Initiation at an Ectopic Mammalian Chromosomal Replication Origin (2004)

A small DNA fragment containing the high-frequency initiation region (IR) ori-beta from the hamster dihydrofolate reductase locus functions as an independent replicator in ectopic locations in both hamster and human cells. Conversely, a fragment of the human lamin B2 locus containing the previously mapped IR serves as an independent replicator at ectopic chromosomal sites in hamster cells. At least four defined sequence elements are specifically required for full activity of ectopic ori-beta in hamster cells. These include an AT-rich element, a 4-bp sequence located within the mapped IR, a region of intrinsically bent DNA located between these two elements, and a RIP60 protein binding site adjacent to the bent region. The ori-beta AT-rich element is critical for initiation activity in human, as well as hamster, cells and can be functionally substituted for by an AT-rich region from the human lamin B2 IR that differs in nucleotide sequence and length. Taken together, the results demonstrate that two mammalian replicators can be activated at ectopic sites in chromosomes of another mammal and lead us to speculate that they may share functionally related elements.

Dynamic modulated brachytherapy (DMBT) for rectal cancer (2012)

Dosimetric properties of a novel DMBT system have been described and evaluated. Comparison with the ICMA commercial applicator has shown it to be a prospective step forward in high-dose-rate brachytherapy (192)Ir technology. Dynamic motion of an applicator during treatment, for any applicator and site in general, can provide additional degrees of freedom that, if properly considered, can potentially increase the plan quality significantly.
Regulation of Vesicle Trafficking in Madin-Darby Canine Kidney Cells by Rab11a and Rab25 (2000)

Polarized epithelial cells maintain the polarized distribution of basolateral and apical membrane proteins through a process of receptor-mediated endocytosis, sorting, and then recycling to the appropriate membrane domain. We have previously shown that the small GTP-binding proteins, Rab11a and Rab25, are associated with the apical recycling system of Madin-Darby canine kidney cells. Here we have utilized inducible expression of wild-type, dominant negative, and constitutively active mutants to directly compare the functions of Rab25 and Rab11a in postendocytic vesicular transport. We found that a Rab11a mutant deficient in GTP binding, Rab11aS25N, potently inhibited both transcytosis and apical recycling yet failed to inhibit transferrin recycling. Similarly, expression of either wild type Rab25 or the active mutant Rab25S21V inhibited both apical recycling and transcytosis of IgA by greater than 50% but had no effect on basolateral recycling of transferrin. Interestingly, the GTPase-deficient mutant Rab11aS20V inhibited basolateral to apical transcytosis of IgA, but had no effect on either apical or basolateral recycling. These results indicate that neither Rab11a nor Rab25 function in the basolateral recycling of transferrin in polarized Madin-Darby canine kidney cells cells, consistent with recent morphological observations by others. Thus, transferrin receptors must be recycled to the plasma membrane prior to sorting of apically directed cargoes into Rab11a/Rab25-positive apical recycling endosomes.
Preparation and characterization of carboxymethyl polyvinyl alcohol–graphite nanosheet composites (2008)

Abstract Carboxymethyl polyvinyl alcohol (CMPVA) was prepared by introducing carboxymethyl groups to polyvinyl alcohol (PVA) with chloroacetic acid. Graphite nanosheets (NanoG) were obtained by treating expandable graphite at a high temperature in a muffle furnace, and then sonicating it in an aqueous ethyl alcohol solution. Nanocomposites of CMPVA with NanoG were prepared by dispersing NanoG in a CMPVA aqueous solution with the aid of sonication and then casted on plastic film to remove water. Carboxymethyl groups were proved to be linked to PVA by Fourier transform infrared (FTIR) spectra and the degree of carboxymethyl substitution on the PVA was 2.77% determined by conductometric titration. Experimental results show that carboxylate anions in introduced carboxymethyl groups facilitate the dispersal of NanoG with positive charges in the CMPVA solution. The CMPVA matrix was detected by X‐ray diffraction (XRD) and FTIR spectra to be less crystal, into which NanoG tend to disperse. Scanning electron microscopy was used to characterize the structure of the graphite and morphology of the composites to prove that NanoG was 40–70 nm thick. The percolation threshold of CMPVA/NanoG composites at room temperature was as low as 0.80 wt%. POLYM. COMPOS., 2008. © 2008 Society of Plastics Engineers
Experimental Dipetalonema reconditum infections in dogs. (1984)

Dipetalonema reconditum is a filarid nematode residing subcutaneously in dogs, and is transmitted by fleas. Previous studies on experimental infections are limited to those by Pennington (1972, Diss. Abst. 33B: 772-B) and Farnell and Faulkner (1978, J. Parasit. 64: 565567). Thus the purposes of our study were: 1) to determine whether dogs could be infected experimentally with D. reconditum by subcutaneous and transmucosal inoculation; 2) to determine whether cats and jirds were susceptible to D. reconditum following subcutaneous inoculation; and 3) to compare microfilaremias during the course of infection in dogs inoculated subcutaneously or transmucosally. A stray dog with a naturally acquired infection was the original source of D. reconditum. Microfilariae were identified by morphological features (Redington, B. C., et al., 1978. In Proceedings of the heartworm symposium '77, G. F. Otto (ed.). Veterinary Medicine Publishing Co., Bonner Springs, Kansas, pp. 14-21) and acid phosphatase activity (Chalifoux and Hunt, 1971, J. Am. Vet. Med. Assoc. 158: 601-605). Ctenocephalides felis pupae were purchased from Environmental Consultants, Inc., Norfolk, Virginia, and reared to adulthood (Smith and Eddy, 1954, Bull. Wld. Hlth. Org. 10: 127-137). Adult fleas were placed on the infected dog and rem ved 10 to 14 days later. Procedures for harvesting infective nematode larvae were similar to those described for Brugia pahangi by McCall (1981, J. Georgia Entomol. Soc. 16: 283-293). In the first experiment, 11 microfilaria-free dogs were inoculated (Table I). Transmucosal and transcutaneous inoculations were performed by placing infective nematode larvae on the vestibular mucosa and shaved skin, respectively, of anesthetized dogs. In addition, two cats and six Mongolian jirds were inoculated subcutaneously with 22 to 25 larvae per animal. In the second experiment, six microfilaria-free Beagles were inoculated subcutaneously and four were inoculated transmucosally with 30 larvae per animal. Modified Knott tests were performed weekly for 28 wk PI. The degree of microfilaremia was com-
Orientational coupling enhancement in a carbon nanotube dispersed liquid crystal (2010)

We present a detailed study of a dilute suspension of carbon nanotubes (CNTs) in a pentylcyanobiphenyl (5CB) liquid crystal (LC) by probing the dielectric properties as a function of applied ac voltage and frequency. In principle, to minimize the elastic distortion in the nematic matrix, the monodispersed CNTs follow the nematic director without disturbing the director field significantly. A strong anchoring energy due to π-π electron stacking between LC-CNT molecules results in an increase in the dielectric anisotropy for the hybrid system, indicating a significant enhancement in the orientational order parameter. The frequency-dependent dielectric anisotropy for the composite system reveals the intrinsic frequency response of the LC-CNT anchoring mechanism. As a matter of consequence, the extracted value of splay elastic constant suggests that LC-CNT anchoring has an impact on the structural modification of the hybrid LC+CNT system. This strong anchoring energy stabilizes local pseudonematic domains, giving rise to a nonzero dielectric anisotropy in the isotropic phase that also shows an intrinsic frequency response.
12.1: 12.1′ SVGA Microencapsulated Electrophoretic Active Matrix Display for Information Appliances (2001)

Abstract We describe the successful construction of a 12.1″ 800×600 microencapsulated electrophoretic active matrix display incorporating an a‐Si thin film transistor backplane. The display exhibits a print‐on‐paper‐like appearance (high reflectance, high contrast ratio and wide viewing angle) and grayscale at 83 DPI, and demonstrates the material's compatibility with commercial a‐Si TFT LCD backplanes.
Hyperspectral Imaging for Detecting Defect on Apples (2005)

The reflectance spectra from the hyperspectral images of apples were used to find theoptimal wavelengths to discriminate the defect region from the normal region. The optimalwavelength was selected from the correlation analysis between the band ratio or wavelengthdifference and target regions. The spectral images of selected wavelength were used to validate thecorrelation analysis. The correlation coefficient value using the band ratio at correlation analysis was0.91 and the using the difference was 0.79. Thus, the correlation analysis method is feasible toselect the wavelength to discriminate defects from normal regions.

[Determination of ammonia in ambient air by ion chromatography]. (2011)

The use of the well-known methods for testing the content of ammonia in the air of a populated area at the average daily maximum allowable concentration (0.04 mg/m3) is associated with the high requirement for chemical reagents and with considerable time. Deionized water proposed to be used as an absorption solution in the sample collector with the final ion chromatographic determination of ammonia is an alternative to solving the problem and enables air ammonia to be determined with a sensitivity of 0.02 mg/dm3.
