Amelogenesis imperfecta: functional and esthetic restoration of a severely compromised dentition. (2000)

The treatment of patients with severe forms of amelogenesis imperfecta presents an interesting challenge to the dental team. A 16-year-old girl presented with a severely compromised occlusion and poor esthetics that had lowered her self-esteem. Preoperative investigations included the determination of completion of growth, an accurate diagnostic waxup, and an evaluation of clinical crown lengths. Periodontal full-flap surgery was planned to lengthen clinical crowns and create gingival harmony. This was to be followed by placement of 28 complete crowns to restore occlusal function and gain a pleasing esthetic result. All-porcelain crowns were placed from premolar to premolar in each arch (20 crowns), and porcelain-fused-to-metal crowns were placed on each molar tooth in each arch (8 crowns). The final treatment result provided this patient with a mutually protective occlusion and with esthetics that greatly enhanced her self-image.
Analysis and design methodology for Planar Transformer with low self-capacitance used in high voltage flyback charging circuit (2016)

In high voltage (HV) flyback charging circuits, the importance of transformer parasitics holds a significant part in the overall system parasitics. The HV transformers have a larger number of turns on the secondary side that leads to higher self-capacitance which is inevitable. The conventional wire-wound transformer (CWT) has limitation over the design with larger self-capacitance including increased size and volume. For capacitive load in flyback charging circuit these self-capacitances on the secondary side gets added with device capacitances and dominates the load. For such applications the requirement is to have a transformer with minimum self-capacitances and low profile. In order to achieve the above requirements Planar Transformer (PT) design can be implemented with windings as tracks in Printed Circuit Boards (PCB) each layer is insulated by the FR4 material which aids better insulation. Finite Element Model (FEM) has been developed to obtain the self-capacitance in between the layers for larger turns on the secondary side. The modelled hardware prototype of the Planar Transformer has been characterised for open circuit and short circuit test using Frequency Response Analyser (FRA). The results obtained from FEM and FRA are compared and presented.

The growth of human scalp hair in females using visible red light laser and LED sources (2014)

LLLT of the scalp at 655 nm significantly improved hair counts in women with androgenetic alopecia at a rate similar to that observed in males using the same parameters.
Armed Oncolytic Adenovirus–Expressing PD-L1 Mini-Body Enhances Antitumor Effects of Chimeric Antigen Receptor T Cells in Solid Tumors (2017)

Chimeric antigen receptor-modified T cells (CAR T cells) produce proinflammatory cytokines that increase expression of T-cell checkpoint signals such as PD-L1, which may inhibit their functionality against solid tumors. In this study, we evaluated in human tumor xenograft models the proinflammatory properties of an oncolytic adenovirus (Onc.Ad) with a helper-dependent Ad (HDAd) that expresses a PD-L1 blocking mini-antibody (mini-body; HD<i>PDL1</i>) as a strategy to enhance CAR T-cell killing. Coadministration of these agents (CAd-VEC<i>PDL1</i>) exhibited oncolytic effects with production of PD-L1 mini-body locally at the tumor site. On their own, HD<i>PDL1</i> exhibited no antitumor effect and CAd-VEC<i>PDL1</i> alone reduced tumors only to volumes comparable to Onc.Ad treatment. However, combining CAd-VEC<i>PDL1</i> with HER2.CAR T cells enhanced antitumor activity compared with treatment with either HER2.CAR T cells alone or HER2.CAR T cells plus Onc.Ad. The benefits of locally produced PD-L1 mini-body by CAd-VEC<i>PDL1</i> could not be replicated by infusion of anti-PD-L1 IgG plus HER2.CAR T cells and coadministration of Onc.Ad in an HER2<sup>+</sup> prostate cancer xenograft model. Overall, our data document the superiority of local production of PD-L1 mini-body by CAd-VEC<i>PDL1</i> combined with administration of tumor-directed CAR T cells to control the growth of solid tumors. <i>Cancer Res; 77(8); 2040-51. ©2017 AACR</i>.
Growth of InxGa1−xAs/GaAs heterostructures using Bi as a surfactant (2000)

The effects of a bismuth surfactant layer on the molecular beam epitaxy of GaAs and InxGa1−xAs layers on GaAs (001) were studied. The InxGa1−xAs surface reconstruction changed from arsenic stabilized 2×4 to bismuth stabilized 1×3 for high enough bismuth fluxes and low enough substrate temperatures. Maintaining a bismuth stabilized surface during InxGa1−xAs growth resulted in a larger number of reflection high-energy electron diffraction (RHEED) oscillations. RHEED patterns were also streakier after InxGa1−xAs growth with Bi. Roughness measurements using atomic force microscopy showed reduced root mean square roughness with Bi, e.g., from 3.8 to 2.8 nm, for 4 nm thick In0.3Ga0.7As layers. Simulations of x-ray diffraction results from 10 period In0.5Ga0.5As/GaAs superlattices showed that Bi reduced interface roughness from 1.1 to 0.5 nm and reduced interfacial broadening from 2.8 to 2.1 nm. The latter was attributed to reduced In segregation. InxGa1−xAs/GaAs (x=0.2–0.4) multiple quantum wells grown with Bi exhibited photoluminescence peaks that were more intense than those grown without Bi.

A Suggestion for a Fast Multiplier (1964)

It is suggested that the economics of present large-scale scientific computers could benefit from a greater investment in hardware to mechanize multiplication and division than is now common. As a move in this direction, a design is developed for a multiplier which generates the product of two numbers using purely combinational logic, i.e., in one gating step. Using straightforward diode-transistor logic, it appears presently possible to obtain products in under 1, μsec, and quotients in 3 μsec. A rapid square-root process is also outlined. Approximate component counts are given for the proposed design, and it is found that the cost of the unit would be about 10 per cent of the cost of a modern large-scale computer.
TEXTURE OF SEMI‐SOLID FOODS: SENSORY AND PHYSICAL CORRELATES (1971)

SUMMARY– Texture profile analyses (TPA) were conducted on a series of commercial desserts (puddings, custards, and gelatin) and on whipped toppings and marshmallow creme. Textural attributes of firmness, elasticity, cohesiveness, gumminess, and chewiness were determined on each product, (a) under compression as in conventional TPA, and (b) under tension to provide five new additional textural parameters. They are referred to as firmness under compression ( Fc ), firmness under tension (F A ), elasticity under compression ( Ec ), elasticity under tension (E A ), etc. Additional attributes of stringiness, maximum tensile force, and work of extension, were also measured. The products were also evaluated by a taste panel for fifteen sensory attributes related to texture. 18 samples were prepared from several products, each of which was altered mainly by using various liquid levels to change the physical and sensory properties. These changes were measured by the conventional TPA method and by the additional procedures described. Precision of the physical test values and precision and reliability of the sensory rating were evaluated. Precision and reliability were deemed sufficient to warrant including all of the physical responses and all of the sensory ratings in a further analysis of the data. Separate factor analyses were performed on the physical test values and on the sensory ratings. Four factors were identified for each set of data, and these accounted for more than 90% of the variation in each case. Multiple regression equations were established for predicting the four factors derived from the sensory ratings by means of the physical test values. Although 15 physical values were available, only 8 were needed for the prediction of the 4 sensory factors. It should be emphasized that some of the additional physical test values obtained under tension, were needed for these predictions as well as the standard physical test values obtained under compression.
Robotic grasping of unmodeled objects using time-of-flight range data and finger torque information (2010)

Robotic grasping in an open environment requires both object-specific as well as general grasping skills. When the objects are previously known it is possible to employ techniques that exploit object models, like geometrical grasping simulators. On the other hand, a competent system will also be able to deal with unmodeled objects using general solutions. In this paper we present an integrated system for autonomous rigid-object pick-up tasks in domestic environments, focusing on the gripping of unmodeled objects and exploiting sensor feedback from the robot hand to monitor the grasp. We describe the perception system based on time-of-flight range data, the grasp pose optimization algorithm and the grasp execution. The performance and robustness of the system is validated by experiments including pick-up tasks on many different common kitchen items.

Genetic Optimization of Metalloenzymes: Enhancing Enzymes for Non‐Natural Reactions (2016)

Artificial metalloenzymes have received increasing attention over the last decade as a possible solution to unaddressed challenges in synthetic organic chemistry. Whereas traditional transition-metal catalysts typically only take advantage of the first coordination sphere to control reactivity and selectivity, artificial metalloenzymes can modulate both the first and second coordination spheres. This difference can manifest itself in reactivity profiles that can be truly unique to artificial metalloenzymes. This Review summarizes attempts to modulate the second coordination sphere of artificial metalloenzymes by using genetic modifications of the protein sequence. In doing so, successful attempts and creative solutions to address the challenges encountered are highlighted.
Critical aspects in the analysis of apoptosis and necrosis. (1998)

Despite that large number of methods to analyze cell death, in particular apoptosis, that have been developed, identification of the mode of cell death and its quantitation is not always simple or straightforward. The difficulties, potential pitfalls and traps in quantitation of dead cells, whether apoptotic or necrotic are reviewed. The following are common flaws in the measurement of cell death, which include incorrect assumptions, erroneous data interpretation and shortcomings of the methodology: 1) Misclassification of apoptotic bodies or chromatin fragments as individual apoptotic cells based on cellular DNA content analysis by flow cytometry; 2) Assumption that the quantity of fragmented DNA extracted from cells represents the frequency of apoptosis; 3) Conjecture that the apoptotic index represents the cell death rate; 4) Assumption that apoptotic cells must exhibit classical features of apoptosis e.g. internucleosomal DNA fragmentation; 5) Inadequacy of methods that presume to discriminate between late apoptotic and necrotic cells; 6) Possibility of a selective enrichment or loss of apoptotic cells during cell separation on density gradients, during trypsinization or other procedures of cell collection; and 7) Inability to distinguish between live, nonapoptotic cells phagocytizing apoptotic bodies and genuine apoptotic cells by flow cytometric methods. Many of the problems stem from the difficulty in identifying apoptotic or necrotic cells. Because apoptosis and necrosis have been originally defined based on morphological criteria it is essential to confirm the mode of cell death by microscopy. Laser scanning cytometry (LSC), which combines the advantages of flow and image cytometry, offers the possibility of morphological examination of apoptotic cells. By virtue of this attribute LSC appears to be the instrument of choice for analysis of apoptosis.
Basing of RAN assets and the force posture review (2012)

Overwhelmingly, Australia's strategic interests are lying in and around our northern waters. Australia is set to develop the second largest reserve of LNG in the world in northwest Australia, and currently has $273.5 billion in new resource commodity projects identified for development, with the majority of new projects taking place within Australia's northern areas. Capital expenditure for 2011 alone for new resource commodity projects is forecasted to be $33.6 billion. What is startling is that over the next ten years, Defence is set to acquire significant capital equipment, mostly in the form of AWDs, LHDs, new frigates and a new submarine fleet costing almost the same amount spent in developing and exporting our resources over the next decade.

ChemInform Abstract: SYNTHESIS AND CHARACTERIZATION OF DINUCLEOSIDE MONOPHOSPHATES CONTAINING 2′‐HALO‐2′‐DEOXYADENOSINES (1981)

Abstract Zur Untersuchung der Korrelation zwischen Struktur und biologischer Wirkung werden aus dem 2′‐Fluor‐desoxyadenosin (Ia) bzw. dem 2′‐Chlor‐desoxyadenosin (Ib) und den Phosphaten (II) sechs verschiedene Dinucleotidmonophosphate (III) hergestellt.
Stress relaxation after steady shearing: Applications and empirical representation (1964)

Abstract The measurement of stresss relaxation following steady‐state shearing is particularly useful in the terminal relaxation zone, where the rheological properties are molecular weight dependent. This paper contains a description of the method as applied to molten polymers, and an empirical function found to be useful for fitting the data. Three examples are given to demonstrate some direct and simple applications. First, the decrease of viscosity with increasing shear rate may be estimated by simply replotting the experimental data. Second, extrapolation of calculated viscosities to very high shear rates is shown to lead to a possible explanation for melt fracture. Third, the true Newtonian viscosity can be estimated from measurements conducted at a nonzero shear rate.
Insulin in human milk: postpartum changes and effect of gestational age (2003)

HMI concentrations were not influenced by gestational age at delivery. They decreased post partum, mainly in mothers of term infants. The postnatal changes in HMI concentrations and the effects of oral insulin on the immature intestinal mucosa warrant further investigation.
NTHU-Route 2.0: A fast and stable global router (2008)

We present in this paper a fast and stable global router called NTHU-Route 2.0 that improves the solution quality and runtime of a state-of-the-art router, NTHU-Route, by the following enhancements: (1) a new history based cost function, (2) new ordering methods for congested region identification and rip-up and reroute, and (3) two implementation techniques. The experimental results show that NTHU-Router 2.0 solves all ISPD98 benchmarks with very good quality. Moreover, it routes 7 of 8 ISPD07 benchmarks without any overflow. In particular, for one of the ISPD07 benchmarks which are thought to be difficult cases previously, NTHU-Route 2.0 can completely eliminate its total overflow. NTHU-Route 2.0 also successfully solves 12 of 16 ISPD08 benchmarks without causing any overflow.
A high-resolution measuring system using coarse optical gratings (1960)

The paper describes a new measuring system, using 100 line/in optical gratings, which contains no moving parts and has been incorporated in both continuous-path and co-ordinate-setting control systems.By a method of cyclic switching of four photocells and subsequent filtering of the combined photocell signals, an a.c. waveform is produced which can be compared in phase with a reference waveform, to determine the magnitude and direction of relative displacement between two gratings, and to provide linear interpolation within the pitch of the gratings.Details of the optical, mechanical and electronic design are given, and the effects of variables on the accuracy of the system are discussed.Interpolation accuracy within ±2 × 10−4in using 100 lines/in gratings has been achieved in practical systems.

Purification and cloning of the salivary nitrophorin from the hemipteran <i>Cimex lectularius</i> (1998)

Cimex lectularius and Rhodnius prolixus contain salivary nitric oxide (NO) that may help them to feed on their vertebrate hosts by promoting vasodilation and inhibiting platelet aggregation. Salivary NO is associated with heme proteins (nitrophorins) that store and transport NO from the insect salivary glands to the skin of the host. In this study, the salivary nitrophorin of Cimex lectularius was purified by DEAE chromatography and reverse-phase high-performance liquid chromatography. The purified nitrophorin had a molecular mass of 32.9 kDa. The DEAE-purified hemoprotein was able to bind NO, and this binding shifted the absorption maximum from 388 nm to 438 nm. The ratio of heme to apoprotein was estimated to be of 1:1. A cDNA clone of 1079 base pairs was sequenced and was found to code for a protein with a molecular mass of 31.7 kDa. The clone sequence was in agreement with the internal peptide sequences obtained from the purified protein. Sequencing of the isolated clone indicates high similarity to several inositol phosphatases; however, no significant similarities emerged when the sequence of C. lectularius nitrophorin was compared with that of R. prolixus nitrophorin, the only other nitrophorin known in insect saliva. Because C. lectularius and R. prolixus belong to two different families of Hemiptera that evolved independently to blood feeding, a case is made for the convergent evolution of these two insect nitrophorins.
