Cell Growth Inhibition by Membrane-Active Components in Brownish Scale of Onion (2006)

The growth-inhibitory effects of the brownish scale components of onion on tumor cells were studied with relating to their membrane activity. Quercetin, quercetin-4'-O-glucoside and two isomeric quercetin dimers (10 μM for each) isolated from the scale reduced the fluidity of tumor cell model membranes consisting of phospholipids and cholesterol more significantly than that of normal cell model membranes. In flavonoidal components, the membrane activity was greatest in the order of dimers, aglycone and glucoside. Quercetin and its dimers intensively acted on the membrane center rather than the membrane surface, while quercetin-4'-O-glucoside was relatively effective on the hydrophilic regions of membranes. Membrane-active flavonoids inhibited the growth of mouse myeloma cells at 10-100 μM with the same rank of order of potency as they rigidified liposomal membranes. Quercetin and its dimers rigidified cell membranes by acting on the hydrophobic inner regions simultaneously with inhibiting the cell growth, but not quercetin-4'-O-glucoside. Flavonoidal components in the brownish scale of onion have the potent anti-proliferative activity associated with the structure-specific rigidification of cell membranes, which is induced by the interaction with membrane lipid bilayers.
Heat Transfer Coefficient in Ducts With Constant Wall Temperature (1983)

An analytical method for the numerical calculation of the heat transfer coefficient in arbitrarily shaped ducts with constant wall temperature at the boundary is presented. The flow is considered to be laminar and fully developed, both thermally and hydrodynamically. The method presented herein makes use of Galerkin-type functions for computation of the Nusselt number. This method is applied to circular pipes and ducts with rectangular, isosceles triangular, and right triangular cross sections. A three-term or even a two-term solution yields accurate solutions for circular ducts. The situation is similar for right triangular ducts with two equal sides. However, for narrower ducts, a larger number of terms must be used.
Electrodeposition of Au Monolayer on Pt(111) Mediated by Self-Assembled Monolayers (2006)

In-situ scanning tunneling microscopy (STM), cyclic voltammetry (CV), and infrared reflection-adsorption spectroscopy (IRRAS) have been used to examine the electrodeposition of gold onto Pt(111) electrodes modified with benzenethiol (BT) and benzene-1,2-dithiol (BDT) in 0.1 M HClO4 containing 10 microM HAuCl4. Both BT and BDT were attached to Pt(111) via one sulfur headgroup. STM and IRRAS results indicated that the other SH group of BDT was pendant in the electrolyte. Both BT and BDT formed (2 x 2) structures at the coverage of 0.25, and they were transformed into (square root(3) x square root(3))R30 degrees as the coverage was raised to 0.33. These two organic surface modifiers resulted in 3D and 2D gold islands at BT- and BDT-coated Pt(111) electrodes, respectively. The pendant SH group of BDT could interact specifically with gold adspecies to immobilize gold adatoms on the Pt(111) substrate, which yields a 2D growth of gold deposition. Molecular resolution STM revealed an ordered array of (6 x 2 square root(13)) after a full monolayer of gold was plated on the BDT/Pt(111) electrode. Since BDT was strongly adsorbed on Pt(111), gold adatoms only occupied free sites between BDT admolecules on Pt(111). This is supported by a stripping voltammetric analysis, which reveals no reductive desorption of BDT admolecules at a gold-deposited BDT/Pt(111) electrode. It seems that the BDT adlayer acted as the template for gold deposit on Pt(111). In contrast, a BT adlayer yielded 3D gold deposit on Pt(111). This study demonstrates unambiguously that organic surface modifiers could contribute greatly to the electrodeposition of metal adatoms.
Increased glycosphingolipid levels in serum and aortae of apolipoprotein E gene knockout mice (2002)

The apolipoprotein E gene knockout (apoE-/-) mouse develops atherosclerosis that shares many features of human atherosclerosis. Increased levels of glycosphingolipid (GSL) have been reported in human atherosclerotic lesions; however, GSL levels have not been studied in the apoE-/- mouse. Here we used HPLC methods to analyze serum and aortic GSL levels in apoE-/- and C57BL/6J control mice. The concentrations of glucosyl ceramide (GlcCer), lactosyl ceramide (LacCer), GalNAcbeta1-4Galbeta1-4Glc-Cer (GA2), and ceramide trihexoside (CTH) were increased by approximately 7-fold in the apoE-/- mouse serum compared with controls. The major serum ganglioside, N-glycolyl GalNAcbeta1-4[NeuNAcalpha2-3]Galbeta1-4Glc-Cer (N-glycolyl GM2), was increased in concentration by approximately 3-fold. A redistribution of GSLs from HDL to VLDL populations was also observed in the apoE-/- mice. These changes were accompanied by an increase in the levels of GSLs in the aortic sinus and arch of the apoE-/- mice. The spectrum of gangliosides present in the aortic tissues was more complex than that found in the lipoproteins, with the latter represented almost entirely by N-glycolyl GM2 and the former comprised of NeuNAcalpha2-3Galbeta1-4Glc-Cer (GM3), GM2, N-glycolyl GM2, GM1, GD3, and GD1a. In conclusion, neutral GSL and ganglioside levels were increased in the serum and aortae of apoE-/- mice compared with controls, and this was associated with a preferential redistribution of GSL to the proatherogenic lipoprotein populations. The apoE-/- mouse therefore represents a useful model to study the potential role of GSL metabolism in atherogenesis.
Wet chemical etching with KOH solutions for fused silica optics manufacturing (2017)

We tested KOH solution as an alternative to HF solution for deep etching operation on fused silica optics. KOH and HF solutions gave very high laser damage resistance on scratches but surface quality is not deteriorated by KOH solution.
Multi-bed elastic motion correction for whole body MR-PET (2014)

Single bed motion correction algorithms are increasingly being used to model and compensate for the respiratory motion in clinical PET images. In this work we develop a multi-bed elastic motion correction algorithm and workflow for the MR-PET (Siemens biograph mMR) scanner. For validation of the proposed multi-bed motion algorithm we performed multi-bed NCAT phantom simulations as well as physical multi-bed rod phantom studies using the clinical scanner. The NCAT and rod phantoms were used as the motion vectors are exactly know and any bias in the final reconstructed image can be easily identified. Finally four patient scans were performed using a two bed protocol. A self-gated radial VIBE MRI sequence was used to generate the gated MR images. The motion vectors were calculated from the gated MR images using demons algorithm. In the mMR system the clinical PET data can be acquired simultaneously along with the MR diagnostic scans of the patient. The list-mode PET data for each bed is divided into pre-determined frames based on the amplitude of the respiratory waveform. The mu-maps corresponding to each frame was generated and used to reconstruct each PET frame separately. A post reconstruction motion correction algorithm was used to compensate for the motion in the different frame of the multi-bed acquisition. Each frame of the multi-bed reconstructed images was warped to the whole body reference image taking into account the acquisition time of each frame as well as the possibility of miss-match in the motion vectors between the beds. The phantom as well as patient studies were motion compensated to the reference image and found to give a faithful whole body reconstruction.
Multiple-Exposure-Patterning-Enhanced Digital Logic Design (2016)

To provide a very rudimentary level of design insight as part of the overall DTCO discussion, this section reviews the primary elements of a digital standard-cell design flow. Of course, a complete system-on-chip (SoC) design contains many more design elements in addition to auto-routed digital logic blocks: memory blocks, analog circuits, I/O designs, and e-fuses, to name a few. Each undergoes DTCO negotiations in a very similar fashion to the elements of the digital-logic-design flow and will be discussed in more detail in Section 3.6.1.
Cyclopentene Annulations of Alkene Radical Cations with Vinyl Diazo Species Using Photocatalysis (2018)

A direct (3+2) cycloaddition between alkenes and vinyl diazo reagents using either Cr or Ru photocatalysis is described. The intermediacy of a radical cation species enables a nucleophilic interception by vinyl diazo compounds, a departure from their traditional electrophilic behavior. A variety of cyclopentenes are synthesized using this method, and experimental insights implicate a direct cycloaddition instead of a cyclopropanation/rearrangement process.

A highly active and durable Co–N–C electrocatalyst synthesized using exfoliated graphitic carbon nitride nanosheets (2015)

Exfoliated graphitic carbon nitride nanosheets (g-C3N4-NS) were applied for the first time for the preparation of an electrocatalyst for the oxygen reduction reaction (ORR). A less dense structure with increased surface area was observed for g-C3N4-NS compared to bulk g-C3N4 from detailed analyses including TEM, STEM, AFM with depth profiling, XRD, and UV-Vis spectroscopy. The pyrolysis of the prepared g-C3N4-NS with Co and carbon under an inert environment provided an enhanced accessibility to the N functionalities required for efficient interaction of Co and C with N for the formation of Co-N-C networks and produced a hollow and interconnected Co-N-C-NS structure responsible for high durability. The Co-N-C-NS electrocatalyst exhibited superior catalytic activity and durability and further displayed fast and selective four electron transfer kinetics for the ORR, as evidenced by various electrochemical experiments. The hollow, interconnected structure of Co-N-C-NS with increased pyridinic and graphitic N species has been proposed to play a key role in facilitating the desired ORR reaction.
Processing experiments for development of high-efficiency silicon solar cells (1990)

Fabrication of high-efficiency silicon solar cells requires processing technology capable of maintaining long bulk carrier lifetime and low surface recombination. Development of long-lifetime processing techniques using experimental designs based on statistical methods is described. The first three experiments investigated pre-oxidation cleans, phosphorus gettering, and a comparison of different phosphorus diffusion sources. Optimal processing parameters were found to depend on type of silicon material. 2 refs., 2 figs., 2 tabs.
Identification of Resonance Frequencies in Dual-Stage Hard Disk Drives: A Practical Strategy (2017)

In hard disk drives (HDDs), there exist multiple mechanical resonances whose central frequencies may shift due to the change of environmental conditions such as the temperature. Such slowly varying resonance frequencies, if not handled properly, may degrade the positioning accuracy and even result in the instability of the closed-loop HDD system. Therefore, it is important to identify these resonance frequencies efficiently without interrupting the reading/writing process in HDDs. One main challenge of the frequency identification in a dual-stage HDD lies in the fact that it is a double-input-single-output (DISO) system. The outputs of the voice coil motor (VCM) and the piezoelectric microactuator (PZT) are coupled together. This paper proposes a practical strategy to identify the resonance frequencies in both the VCM and the PZT without disabling the PZT control process. Bandpass filters are utilized to separate the overall position error signal (PES) into several frequency segments based on priorly-known frequency range for each resonance. Two standard parameter adaptation algorithms are studied and discussed. Simulation results validate the effectiveness of proposed identification strategy.
Orientation Control of Photo‐Immobilized Antibodies on the Surface of Azobenzene‐Containing Polymers by the Introduction of Functional Groups (2010)

In our photo-induced immobilization technique for an antibody (IgG) using azopolymers, the introduction of COOH and NMe(2) into the azopolymers, which can introduce surface charges, strongly affected the immobilization properties such as the efficiency of immobilization and the activity of the immobilized IgG (i.e., the orientation of the immobilized IgG). The introduction of COOH promoted a more active orientation of the immobilized IgG. The orientation was determined during the adsorption process onto the azopolymer surface in solution before photo-immobilization, and was maintained during the photo-immobilization. The surface charge of the azopolymer appears to be an important factor for IgG orientation, which involves electrostatic interactions between its Fab and the azopolymer surface.
Influence of the Demultiplexer on Channel-Interleaved Photonic Analog-to-Digital Converters (2020)

We investigate the demultiplexer in channel-interleaved photonic analog-to-digital converter (CI- PADC) and its influence on the performance of CI- PADC system by frequency domain modeling. The theoretical analysis reveals that the output power of the signal in different frequency sections is affected by the demultiplexer in different degrees. Subsequently, a method based on the derived figure of merit (FoM) is proposed to quantitatively evaluate and effectively minimize the impact of the demultiplexer on the signal in different frequency sections. According to the theoretical analysis, a CI- PADC system demultiplexed via dual-output Mach-Zehnder modulators is implemented to study and optimize the influence of demultiplexer. The experimental results with a flat frequency response in the range of 20 GHz verify the feasibility of the proposed method.
Understanding the effect of sodium polyphosphate on improving the chemical stability of Ti3C2Tz MXene in water (2022)

We study the effect of sodium polyphosphate upon Ti 3 C 2 T z MXene degradation in aqueous colloids. This study also illustrates an effective and useful method for separation of the two main processes leading to MXene degradation in aqueous environments.
Transforming activity and tissue tropism of hybrid retroviral genomes containing portions of the v-abl and v-src oncogenes. (1993)

The v-abl and v-src oncogenes encode activated cytoplasmic tyrosine kinases with considerable sequence similarity. The v-abl oncogene of the Abelson murine leukemia virus exhibits a narrow tissue tropism for transformation, almost exclusively forming pre-B-cell tumors, while the v-src oncogene can induce a variety of sarcomas and other tumors. To localize the determinants of the narrow tropism of the v-abl gene, we generated a series of hybrid retroviral genomes containing portions of the v-abl and v-src oncogenes in a Moloney murine leukemia virus backbone. Each virus was tested for transforming activity in NIH3T3 cells; for transforming activity on bone marrow cultures; and for pathogenicity in newborn mice. Many of the hybrid oncogenes carried by these viruses exhibited transforming activity, and demonstrate that the SH2 domain of each oncogene can be utilized by the kinase domain of the other oncogene for that activity. The results further suggest that a portion of the C-terminal region of v-abl is necessary for the pre-B-cell specificity of the oncogene.
Microdisk-Based Full Adders for Optical Computing in Silicon Photonics (2018)

We experimentally demonstrate a two-bit thermal-optic ripple-carry full adder based on microdisk resonators in silicon photonics with the advantages of large bandwidth, low power consumption, and high scalability, paving the way to future optical computing.
Technical feasibility evaluation of fluorescence signal detection by compact photonic explorer for better health (2004)

The lowest detectable fluorescence signal level from biomedical specimens have been determined using a spectrometer, cooled CCD detector, and PIN photodiode with 365 nm UV LED light excitation. The data indicates the PIN photodiodes have adequate sensitivity for detection of tissue fluorescence with a sufficient signal-to-noise ratio. This data is being used to design a "pill-sized" Compact Photonics Explorer (CPE) for in vivo cancer optical diagnostics.

Comparison of Nonmydriatic Optos® Fundus Imaging with Mydriatic Early Treatment Diabetic Retinopathy Study (ETDRS) 7-Standard Field Stereo Photography and Clinical Grading (2011)

Methods: Subjects underwent nonmydriatic Optos100 and 200 degree imaging, dilated ETDRS photography and dilated fundoscopic examination by a masked retina specialist. Images were graded by two independent masked readers according to a strictly defined protocol. Each image was graded for presence and extent of specific diabetic lesions as well as for overall clinical DR severity. A third masked retina specialist adjudicated any discrepancies. Unweighted (K) and weighted (KW) kappa statistics (linear scale) assessed agreement (almost perfect 0.81-1.0, substantial 0.61-0.80, moderate 0.41-0.60).

Coupling light to nanostructures via plasmons (2005)

This article outlines some of the recent studies on light manipulation and molecule sensing with plasmonic nanostructures. Studies show that plasmonic nanostructures can serve as optical couplers across nano-micro interface, and recent advances in this emerging area now enable researchers to mount a systematic approach toward the goal of full system-level integration.
