Inhibition of green algae growth by corrole-based photosensitizers (2014)

Phototrophic biofilms are an important factor in biofouling and biodeterioration of building materials, causing great damage to historic and contemporary constructions. Growth inhibition of phototrophic organisms using photodynamic inactivation could pose an alternative to the use of biocides. To this end, successful application of this approach on green algae is a vital step in the development of suitable photosensitizers.
Hemodynamic Controller for Left Ventricular Assist Device Based on Pulsatility Ratio (2007)

Hemodynamic control of left ventricular assist devices (LVADs) is generally a complicated problem due to diverse operating environments and the variability of the patients: both the changes in the circulatory and metabolic parameters as well as disturbances that require adjustment to the operating point. This challenge is especially acute with control of turbodynamic blood pumps. This article presents a pulsatility ratio controller for LVAD that provides a proper perfusion according to the physiological demands of the patient, while avoiding adverse conditions. It utilizes the pulsatility ratio of the flow through the pump and pressure difference across the pump as a control index and adjusts the pump speed according to the reference pulsatility ratio under the different operating conditions. The simulation studies were performed to evaluate the controller in consideration of the sensitivity to afterload and preload, influence of the contractility, and effect of suction sensitivity. The controller successfully adjusts the pump speed according to the reference pulsatility ratio, and supports the natural heart under diverse pump operating conditions. The resulting safe pump operations demonstrate the solid performance of the controller in terms of sensitivity to afterload and preload, influence of the contractility, and effect of suction sensitivity.

Metal–Organic Frameworks with Zero and Low‐Valent Metal Nodes Connected by Tetratopic Phosphine Ligands (2022)

Metal-organic frameworks (MOFs) constructed with M<sup>0</sup> nodes are attractive targets due to the reactivity of these low-valent metals, but examples of these MOFs remain exceedingly rare. The rational design of three-dimensional MOFs with Pd<sup>0</sup> and Pt<sup>0</sup> nodes using tetratopic phosphine ligands is reported. Five new MOFs have been synthesized by systematic variation of the phosphine ligands and metal precursors employed, and these represent the first examples of MOFs constructed using phosphine-metal bonds as the sole structural component. The MOFs display solid-state luminescence, with emission maxima that are significantly red-shifted compared to Pd(PPh<sub>3</sub> )<sub>4</sub> . In addition, a Rh<sup>I</sup> low-valent coordination solid based on the same linker design is reported, which displays solid-state luminescence that is not observed for the molecular analogue.
90K (Mac-2 BP) in human milk (1996)

Human 90K, also known as Mac-2 binding protein (Mac-2 BP), is a secreted glycoprotein which is widely expressed, binds to the human macrophage-associated lectin Mac-2, and may have a role in host defence. We have measured the concentrations of 90K in human breast milk from eight healthy mothers delivering mature healthy infants after full-term pregnancy using a specific immunoenzymatic assay. Maximal 90K concentrations were observed on days 2-3 post-partum, and ranged from 13.4 to 79.2 microg/ml. The concentrations of 90K in the milk had no correlation with those in the maternal blood.
Use of18F-ASEM PET to Determine the Availability of the α7-Nicotinic Acetylcholine Receptor in Recent-Onset Psychosis (2018)

Limited postmortem evidence suggests a diminished availability of the α7 nicotinic acetylcholine receptor (α7-nAChR) in hippocampus in psychosis. <b>Methods:</b> In this cross-sectional PET study, we used <sup>18</sup>F-ASEM, a radiotracer targeting the α7-nAChR, with positron emission tomography to compare the binding of <sup>18</sup>F-ASEM in hippocampus between individuals with recent-onset psychosis and healthy controls. <b>Results:</b> Individuals with recent-onset psychosis [non-affective psychosis (NP) or affective psychosis], and particularly those with NP, showed lower hippocampal binding of <sup>18</sup>F-ASEM than healthy controls. Among patients, lower binding was associated with lower performance in two cognitive domains after controlling for age. <b>Conclusion:</b> Low availability of the α7-nAChR in hippocampus may be linked to recent-onset of psychosis. Further study is needed to assess its clinical relationship to neuropsychiatric symptoms.

Palladium-Catalyzed Synthesis of Novel Optically Active Tryptophan Analogues (2003)

[reaction: see text] Both unsaturated proline derivatives and optically active tryptophan analogues have been obtained via Pd-catalyzed cyclization of aniline-containing acetylenic amino acids. The side chain length of the cyclization precursor determines which one of the two possible products will be formed.
On the convergence of joint channel and mismatch estimation for time-interleaved data converters (2011)

Mostly digital architectures for communication transceivers rely on the use of accurate analog-to-digital converters (ADCs), which becomes a bottleneck in scaling to multi-Gigabit speeds. A promising workaround is to employ slower, power-efficient sub-ADCs in a time-interleaved ADC (TI-ADC) architecture. While mismatch between sub-ADCs can lead to performance floors, recent work shows that this can be mitigated using joint channel and mismatch compensation algorithms. In this paper, we investigate the scalability and convergence of a recently proposed iterative channel and mismatch estimation algorithm, and derive rules of thumb relating the required length of training to the number of sub-ADCs.
Performance and Stability Enhancement of Dye‐Sensitized and Perovskite Solar Cells by Al Doping of TiO2 (2014)

Reversible photo‐induced performance deterioration is observed in mesoporous TiO 2 ‐containing devices in an inert environment. This phenomenon is correlated with the activation of deep trap sites due to astoichiometry of the metal oxide. Interestingly, in air, these defects can be passivated by oxygen adsorption. These results show that the doping of TiO 2 with aluminium has a striking impact upon the density of sub‐gap states and enhances the conductivity by orders of magnitude. Dye‐sensitized and perovskite solar cells employing Al‐doped TiO 2 have increased device efficiencies and significantly enhanced operational device stability in inert atmospheres. This performance and stability enhancement is attributed to the substitutional incorporation of Al in the anatase lattice, “permanently” passivating electronic trap sites in the bulk and at the surface of the TiO 2 .

Electrical characteristics and stability of gold and palladium Schottky contacts on ZnO nanorods (2008)

The electrical characteristics and stability of Pd and Au Schottky contacts on ZnO nanorods grown on glass substrate have been investigated. The nanorods were grown using the aqueous chemical growth method. The nanorods were characterized with scanning electron microscopy (SEM), x-ray diffraction (XRD) and photoluminescence (PL). Prior to the metal contact deposition, an insulating PMMA layer was deposited between the nanorods. The best-produced Schottky contact was an as-deposited Pd/ZnO contact with an ideality factor of 1.74 ± 0.43 and a barrier height of 0.67 ± 0.09 eV. The relatively high ideality factor indicates that the current transport cannot be described by pure thermionic transport. The presence of surface states due to the high evaporation pressure is probably the reason for the high ideality factor. Post metal deposition annealing at 150 °C for 30 min in air lowered the barrier height and decreased the Au/ZnO ideality factor but increased it for Pd/ZnO. The current follows ohmic behavior when the applied forward bias, V(forward), is lower than 0.1 V, whereas for V(forward) between 0.1 and 0.45 V the current follows I∼exp(cV), and at higher forward biases the current-voltage characteristics follow the relation I∼V(2), indicating that the space-charge current-limiting mechanism is dominating the current transport.
Cross‐Linking of Thiolated Paclitaxel–Oligo(p‐phenylene vinylene) Conjugates Aggregates inside Tumor Cells Leads to “Chemical Locks” That Increase Drug Efficacy (2018)

How to reduce the resistance of certain tumor cells to paclitaxel (PTX) and related taxoid anticancer drugs is a major challenge for improving cure rates. An oligo(p-phenylenevinylene) unit with thiol groups and a PTX unit (OPV-S-PTX), which enhances drug efficacy and reverses resistance is thus designed. The mechanism involves diffusion of OPV-S-PTX into the cell, where π-π interactions lead to aggregation. Cross-linking of the aggregates via oxidation of thiol groups is favored in tumor cells because of the higher reactive oxygen species (ROS) concentration. Cross-linked aggregates "chemically lock" the multichromophore particle for a more persistent effect. The IC<sub>50</sub> of OPV-S-PTX for tumor cell line A549 is reduced down to 0.33 × 10<sup>-9</sup> m from that observed for PTX itself (41 × 10<sup>-9</sup> m). Enhanced efficacy by OPV-S-PTX is proposed to proceed via acceleration of microtubule bundle formation. A549/T-inoculated xenograft mice experiments reveal suppression of tumor growth upon OPV-S-PTX treatment. Altogether, these results show that the internal cross-linking of OPV-S-PTX through ROS provides a means to discriminate between tumor and healthy cells and the formation of the chemically locked particles enhances drug efficacy and helps in reducing resistance.

Meso‐Epitaxial Solution‐Growth of Self‐Organizing Discotic Liquid‐Crystalline Semiconductors (2003)

Substituted hexabenzocoronenes (HBCs) form films with supramolecularly ordered columnar stacks that are uniaxially oriented onto poly(tetrafluoroethylene) alignment layers (see Figure). In field‐effect transistor (FET) tests, mobilities of up to 10 –3 cm 2 V –1 s –1 and high on–off ratios of more than 10 4 were derived for these aligned HBC films, characteristics superior to FETs prepared from isotropic HBC layers.
Molecular beam epitaxy (MBE) HgCdTe infrared focal plane array (IRFPA) flexible manufacturing (1994)

Extensive material and device statistics of performance and reproducibility are presented to show the maturity of this technology. The demonstration vehicles to monitor yields during this demonstration were long-wavelength infrared (LWIR) HgCdTe multilayer wafers with 128 X 128 detector arrays. The heterostructure photodetectors were of the p-on-n planar configuration. Device data show that MBE LWIR diode test structures have performance that equals that of p-on-n double heterostructure photodiodes made by LPE. Due to the special attention given to understanding and reducing epilayer growth-induced defects, we have achieved improvements in FPA operability values from 92% to 98%. These improvements have resulted in the demonstration of a 128 X 128 FPA hybrid that had detectivity (D*) background limited performance when operating at 80 K in a tactical background environment. Mean D* was 1.28 X 10<SUP>11</SUP> cmHz<SUP>1/2</SUP>/W. The corresponding mean NE(Delta) T was an excellent 5.9 mK.

Design of a linearly-polarized high-directivity microstrip patch antenna (2015)

This paper presents a microstrip patch antenna (MPA) with linear polarization and high-directivity, suitable for the use in base stations. Genetic algorithm (GA) is used to design the patch geometry and feeding position to resonate the antenna around 4 GHz. The patch has a rectangular foot print of 200 × 40 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and is etched on a substrate of 240 × 80 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The substrate is 1.52 mm thick and has a relative permittivity of 3.38. The MPA shows a maximum directivity of 13.2 dB at 4.04 GHz in broadside direction and can be used to replace an array having the same area. The simulations have been carried out in the HFSS environment.
Early Cost Effectiveness of Whole-Genome Sequencing as a Clinical Diagnostic Test for Patients with Inoperable Stage IIIB,C/IV Non-squamous Non-small-Cell Lung Cancer (2021)

Our analysis suggests that providing WGS as a diagnostic test is cost effective compared with SoC followed by WGS and SoC alone if costs for WGS decrease and additional patients with actionable targets are identified. This cost-effectiveness model can be used to incorporate new findings iteratively and to support ongoing decision making regarding the use of WGS in this rapidly evolving field.
Kinematic path planning for space-based robotics (1998)

Future space robotics tasks require manipulators of significant dexterity, achievable through kinematic redundancy and modular reconfigurability, but with a corresponding complexity of motion planning. Existing research aims for full autonomy and completeness, at the expense of efficiency, generality or even user friendliness. Commercial simulators require user-taught joint paths—a significant burden for assembly tasks subject to collision avoidance, kinematic and dynamic constraints. Our research has developed a Kinematic Path Planning (KPP) algorithm which bridges the gap between research and industry to produce a powerful and useful product. KPP consists of three key components: path-space iterative search, probabilistic refinement, and an operator guidance interface. The KPP algorithm has been successfully applied to the SSRMS for PMA relocation and dual-arm truss assembly tasks. Other KPP capabilities include Cartesian path following, hybrid Cartesian endpoint/intermediate via-point planning, redundancy resolution and path optimization. KPP incorporates supervisory (operator) input at any detail to influence the solution, yielding desirable/predictable paths for multi-jointed arms, avoiding obstacles and obeying manipulator limits. This software will eventually form a marketable robotic planner suitable for commercialization in conjunction with existing robotic CAD/CAM packages.

Novel Synthesis of Lactosyl .BETA.-Glycosides and Analogs through Cellulase-mediated Transglycosylation or Condensation Reaction (2004)

Alkyl β-lactosides were directly synthesized by β-lactosyl transfer reaction from p-nitrophenyl β-lactoside (Lacβ-pNP) to various 1-alkanols (n=2-12), utilizing a commercially available cellulase preparation of Trichoderma reesei C1. When 1-octanol and dodecanol were acceptors, octyl β-lactoside and dodecyl β-lactoside were obtained as transfer products, respectively. Furthermore, the enzyme catalyzed N-acetyllactosaminyl transfer reaction from p-nitrophenyl β-N-acetyllactosaminide (LacNAcβ-pNP) not only to 1-alkanol, but also to the OH-4 position of Man and Glc to produce the trisaccharides. As an alternative method, alkyl β-lactosides were synthesized by condensation reaction of lactose with alkanols. When various 1-alkanols (n: 2-8) were used, the corresponding alkyl β-lactosides were obtained in the yields of 1-4% based on lactose added. Further, condensation reaction between lactose and glycerol was effectively catalyzed to produce 1-O-β-lactosyl-(R,S)-glycerols and 2-O-β-lactosyl glycerol in a molar ratio of 7:3 and in a 20% yield based on lactose added. The enzyme also catalyzed the condensation with 2-propanol and allyl alcohol. In a similar manner, when LacNAc was used as a glycon substrate, the enzyme catalyzed the condensation with various alkanols and glycerol. The yields were lower than those obtained from reactions with lactose. Finally, purification of an enzyme possessing condensation activity was carried out by chromatographies using DEAE-Sepharose and Mono P columns, in order to reveal whether the same enzyme molecule would catalyze in both the lactosyl- and N-acetyllactosaminyl-condensing reactions. It was specified that a single enzyme works both condensation reactions, based on the substrate competition assay on hydrolysis.
A scalar variational analysis of rectangular dielectric waveguides using Hermite-Gaussian modal approximations (1995)

A scalar variational analysis of rectangular dielectric waveguides using Hermite-Gaussian modal approximations is presented. The technique analyzes waveguides by finding a closed-form, approximate solution to the given problem. We begin with an assumed, closed-form field solution, with unknown parameters which can be chosen to best match the assumed field to the actual field solution using variational principles. The values of the unknown parameters of the assumed field are determined by solving a set of simultaneous equations, not by a search method. As a result, this analysis method is computationally fast. Another benefit is that this method gives best-fit, closed-form modal approximations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Electronic Structures of Group III–V Element Haeckelite Compounds: A Novel Family of Semiconductors, Dirac Semimetals, and Topological Insulators (2022)

Abstract The family of III–V element compounds (i.e., XY compounds; X = B, Al, Ga, In, or Tl; Y = N, P, As, or Sb) have been intensively investigated for several decades because of their enormous applications for many optoelectronic devices. Here, by employing first‐principles calculations, the electronic structures of bulk XY haeckelite compounds are examined. It is identified that InSb (TlN and TlP) is Dirac semimetal (are strong topological insulators). The other fifteen XY compounds are semiconducting. The effect of biaxial and uniaxial tensile and compressive strains on the electronic structures are studied. These materials offer diverse topological orders. The semiconducting band gaps are mainly found between the bonding and antibonding states of the mixed X ( p )– Y ( p ) orbitals at the top of the valence band and the bottom of the conduction bands, respectively. The topological insulating nature of the XY compounds is explained based on the degenerate p x + p y orbitals and their orbital energies relative to the p z orbitals near the Fermi energy. The nontrivial band topologies of TlN and TlP are confirmed by calculating the Z 2 (1;000) index, surface states, and Wilson loop calculations. The bands split into two branches by including spin‐orbit interaction. The results demonstrate that haeckelite compounds are fascinating materials with broad potential applications in optoelectronics and possessing the possibility of hosting emergent physical phenomena.
