Pseudocapacitive Hausmannite Nanoparticles with (101) Facets: Synthesis, Characterization, and Charge‐Transfer Mechanism (2013)

Hausmannite Mn3 O4 octahedral nanoparticles of 18.3 ± 7.0 nm with (101) facets have been prepared by an oxygen-mediated growth. The electrochemical properties of the Mn3 O4 particles as pseudocapacitive cathode materials were characterized both in half-cells and in button-cells. The Mn3 O4 nanoparticles exhibited a high mass-specific capacitance of 261 F g(-1), which was calculated from cyclic voltammetry analyses, and a capacitive retention of 78% after 10,000 galvanostatic charge-discharge cycles. The charge-transfer mechanisms of the Mn3 O4 nanoparticles were further studied by using synchrotron-based in situ X-ray absorption near edge spectroscopy and XRD. Both measurements showed concurrently that throughout the potential window of 0-1.2 V (vs. Ag/AgCl), a stable spinel structure of Mn3 O4 remained, and a reversible electrochemical conversion between tetrahedral [Mn(II) O4 ] and octahedral [Mn(III) O6 ] units accounted for the redox activity. Density functional theory calculations further corroborated this mechanism by confirming the enhanced redox stability afforded by the abundant and exposed (101) facets of Mn3 O4 octahedra.
Effect of tungsten additions on the field-induced piezoelectric properties of Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-PbTiO/sub 3/ ceramics (2002)

The objective of this research was to characterize the dielectric and induced piezoelectric properties of W/sup 6+/-doped, 0.87 Pb(Mg/sub 1/3/Nb/sub 2/3/)O/sub 3/-0.13PbTiO/sub 3/ relaxor ferroelectrics. The induced k/sub t/'s depended strongly on the W/sup 6+/ amount and electric field, maximizing at a value of 0.58 for an applied field of 6 kV/cm and a 1% doping level. In addition, only slight variations in the sintering temperature (/spl plusmn/10/spl deg/C) had a pronounced effect on the properties, decreasing the k/sub t/ by as much as 10%.
Barrier Membrane Techniques In Endodontic Microsurgery (1997)

The ultimate goal in endodontic microsurgery is the predictable regeneration of periapical tissues. One of the main concerns in treating an endodontically treated tooth which has a through-and-through osseous defect is that incomplete bone healing may be inevitable. This article reviews the use of different barrier membranes for bone regeneration. In addition, the indications, techniques, and prognosis of calcium sulfate in guided bone regeneration are presented.
Estimation of Flash Memory Level Distributions Using Interpolation Techniques for Optimizing the Read Reference (2015)

For NAND Flash memory, a read comprises reading the word line at a particular read reference voltage. The read reference voltage is critical as it determines the bit error rate. For equi- probable levels, the optimum read reference is at the intersection of the level probability density functions. In this paper, we propose two methods to obtain the optimum read reference voltage. The first method comprises estimating the parameters of the level's cumulative distribution function. Knowledge of the parameters can then be used to obtain the optimum read reference voltage. In order to estimate the parameters, multiple reads from the Flash memory have to be performed. For latency considerations, we are constrained by the number of allowed reads and want to minimize them. The reads from the Flash memory coupled with the error correcting code output are used to obtain the distribution values. This method involves computing the inverse of the cumulative distribution function to obtain the mean and variance of the distributions. The inverse of the cumulative distribution function is highly sensitive to the measurement noise. Hence, this method needs more reads to mitigate the effects of the measurement noise. The second method consists of using bounded functions based on polynomials to interpolate the cumulative distribution function between the measured values and extrapolate it beyond. This method is more robust to measurement noise. We performed simulations using real Flash memory data to validate the algorithms. The distribution fits we obtain are very close to the actual histograms in the tail region of the distributions. This leads to obtaining bit error rates close to optimum. We extend the method developed for single level cell case to the multi level cell Flash memory, with the upper page read accompanied by the lower page read. In further extensions, we make use of the knowledge of channel impairments and the variance of the distribution over cycles to estimate the cumulative distribution function for the case of only one read from the Flash memory. Simulation results show one order of improvement in the bit error rate using these algorithms.
A phase II, dose finding, placebo-controlled, study of zuclomiphene citrate to amerliorate the frequency and severity of hot flashes caused by androgen deprivation in men with advanced prostate cancer. (2019)

TPS338 Background: Androgen deprivation therapy (ADT) is the mainstay of treatment for advanced prostate cancer. ADT not only lowers testosterone, but also decreases estrogen levels which can cause significant side effects including hot flashes, loss of bone and bone fractures, and decreases in libido. Up to 80% of the men on ADT report hot flashes and 30-40% of men have moderate to severe hot flashes. Concern over hot flashes make patients less likely to begin ADT and can lead to early discontinuation of ADT. While the off-label use of potent steroidal estrogens has demonstrated efficacy, the appropriate dose as well as dosing route or schedule of these potent estrogens, has not been established. Furthermore, the potential for safety issues with potent steroidal estrogens remains a significant limitation to their clinical utility. Zuclomiphene citrate, is novel weak nonsteroidal estrogenic agent that should ameliorate hot flashes caused by ADT, and as one of the isomers of clomiphene, has a 50 year safety history of being well tolerated in men. Methods: The Phase 2, placebo controlled, dose finding clinical trial (V72203) evaluating zuclomiphene citrate (VERU-944) capsules, oral daily dosing, for the treatment of moderate to severe hot flashes in men with prostate cancer on ADT is in progress. Men are randomized to daily doses of placebo or zuclomiphene 10mg, 50mg or 100mg. V72203 is enrolling approximately 36 men per arm in 10 sites in the United States. The primary efficacy endpoint is the mean change in frequency of moderate and/or severe hot flashes from baseline to week 4 and maintained until week 12. Secondary endpoints include changes from baseline in bone turnover markers, free and total testosterone, SHBG, PSA, and safety. Hot flashes are being measured in real time utilizing an electronic data capture device (ePRO) provided to each subject. We anticipate completion of enrollment by the end of 2018 with study results by second quarter of 2019. Clinical trial information: NCT03646162.
Impact of bulk cardiac motion on right coronary MR angiography and vessel wall imaging (2001)

The purpose of this study was to investigate the impact of in-plane coronary artery motion on coronary magnetic resonance angiography (MRA) and coronary MR vessel wall imaging. Free-breathing, navigator-gated, 3D-segmented k-space turbo field echo ((TFE)/echo-planar imaging (EPI)) coronary MRA and 2D fast spin-echo coronary vessel wall imaging of the right coronary artery (RCA) were performed in 15 healthy adult subjects. Images were acquired at two different diastolic time periods in each subject: 1) during a subject-specific diastasis period (in-plane velocity <4 cm/second) identified from analysis of in-plane coronary artery motion, and 2) using a diastolic trigger delay based on a previously implemented heart-rate-dependent empirical formula. RCA vessel wall imaging was only feasible with subject-specific middiastolic acquisition, while the coronary wall could not be identified with the heart-rate-dependent formula. For coronary MRA, RCA border definition was improved by 13% (P < 0.001) with the use of subject-specific trigger delay (vs. heart-rate-dependent delay). Subject-specific middiastolic image acquisition improves 3D TFE/EPI coronary MRA, and is critical for RCA vessel wall imaging.
How Did You like 2017? Detection of Language Markers of Depression and Narcissism in Personal Narratives (2018)

Language analyses reveals crucial information about an individual's current state of mind.Maladaptive psychological functioning appears in cognition, emotional experience and behaviour.In the time of the internet of things, a vast number of text and speech is available; subsequently, the interest in the automated detection of psychological functioning via language is rising.The current study indicates that depression and narcissism can be predicted through word use in personal narratives.Both conditions are characterised by an altered word count regarding anxiety and we (LIWC-based).While depressive individuals use less social words and more anxietyrelated words, narcissists do the opposite.This might reflect the verbal correlate of the cognitive triad in depression.In contrast, narcissists' word use mirrors their excommunicated anxiety of being an undesired self and their inability to reach long-term goals due to a lack of impulse control.The automated recognition of mental state through word use could improve early detection of mental disease, monitoring of disease course, delivery of tailored interventions and evaluation of therapy outcome.
white paper The Impact of Product Identity on Industrial Control Part 1: "See More, Do More…" (2003)

Sensing of the specific identity of products moving through the manufacturing supply chain is generally indirect. Typically such information is inferred from local proximity sensor readings coupled with appropriate computer based tracking models, which align these readings to the last known point of identity recognition. Automated Identification systems promise to address some of the limitations of these approaches by providing automated, item level, product identity information at any point in the supply chain. Technically speaking, the impact of product identity is to enhance the visibility or observability of the state of a production, storage, transportation and retail processes that a product is subject to during its life cycle. Enhanced observability means more accurate, timelier data and ultimately a greater scope for optimisation and customisation of the operation concerned. Hence the title “See More, Do More…” This paper examines the notion of observability, illustrates what it means for physical operations and outlines practical implications for industrial control systems. A materials handling example is used as an illustration. A second white paper will examine product identity and its impact on customisation.
Hydrothermal/Solvothermal Crystal Growth: an Old but Adaptable Process (2014)

Abstract Hydrothermal crystal growth can be described as a low temperature process under pressure using an aqueous solution as the solvent. The temperature gradient controls the transport phenomenon from the nutrient to the seeds. The solvothermal term is generally used when the solvent is a non‐aqueous solution. Different aspects will be particularly discussed: (a) The principle of hydrothermal/solvothermal crystal growth processes. (b) A brief history of the development of such processes. (c) The main factors involved during the crystal growth and their impact on the quality of the resulting macroscopic single crystals. (d) How these physical and chemical factors can be optimized to improve the quality of the crystals. The conclusions focus on the future developments of hydrothermal or solvothermal crystal growth processes.
Drosha-independent miR-6778–5p strengthens gastric cancer stem cell stemness via regulation of cytosolic one-carbon folate metabolism (2020)

Drosha-dependent canonical microRNAs (miRNAs) play a crucial role in the biological functions and development of cancer. However, the effects of Drosha-independent non-canonical miRNAs remain poorly understood. In our previous work, we found a set of aberrant miRNAs, including some upregulated miRNAs, called Drosha-independent noncanonical miRNAs, in Drosha-knockdown gastric cancer (GC) cells. Surprisingly, Drosha-silenced GC cells still retained strong malignant properties (e.g., proliferation ability and cancer stem cell (CSC) characteristics), indicating that aberrantly upregulated non-canonical miRNAs may play an important role in the maintenance of the malignant properties in GC cells that express low Drosha levels. Here, we report that miR-6778-5p, a noncanonical miRNA, acts as a crucial regulator for maintenance of CSC stemness in Drosha-silenced GC cells. MiR-6778-5p belongs to the 5'-tail mirtron type of non-canonical miRNAs and is transcript splice-derived from intron 5 of SHMT1 (coding cytoplasmic serine hydroxymethyltransferase). It positively regulates expression of its host gene, SHMT1, via targeting YWHAE in Drosha-knockdown GC cells. Similar to its family member SHMT2, SHMT1 plays a crucial role in folate-dependent serine/glycine inter-conversion in one-carbon metabolism. In Drosha wild type GC cells, SHMT2 mediates a mitochondrial-carbon metabolic pathway, which is a major pathway of one-carbon metabolism in normal cells and most cancer cells. However, in Drosha-silenced or Drosha low-expressing GC cells, miR-6778-5p positively regulates SHMT1, instead of SHMT2, thus mediating a compensatory activation of cytoplasmic carbon metabolism that plays an essential role in the maintenance of CSCs in gastric cancer (GCSCs). Drosha wild type GCSCs with SHMT2 are sensitive to 5-fluorouracil; however, Drosha low-expressing GCSCs with SHMT1 are 5-FU-resistant. The loss of miR-6778-5p or SHMT1 notably mitigates GCSC sphere formation and increases sensitivity to 5-fluorouracil in Drosha-knockdown gastric cancer cells. Thus, our study reveals a novel function of Drosha-independent noncanonical miRNAs in maintaining the stemness of GCSCs.

Diurnal change of retinal vessel density related to hemodynamic variation in treatment-naïve low-teens normal-tension glaucoma (2023)

This study undertook to investigate the diurnal variation of optical coherence tomography angiography (OCTA) -derived retinal vessel density (RVD) in glaucoma patients with low baseline intraocular pressure (IOP). A prospective evaluation was performed on low-teens normal-tension glaucoma (low-teens NTG) patients with pre-treatment IOP < 15 mmHg and 32 healthy subjects. Superficial peripapillary and macular RVD by OCTA, IOP, and systemic blood pressure (BP) were all measured four times per day (from 9:00 a.m. to 6:00 p.m.). In the low-teens NTG group, the magnitude of diurnal changes in peripapillary RVD and macular RVD were greater than those in the healthy group. Diurnal variations of diastolic BP (DBP) and mean ocular perfusion pressure (MOPP) also were greater in the low-teens NTG group. As for the patterns of diurnal RVD change, the inferior and temporal sections of macular RVD showed significant differences between the two groups. Diurnal changes of RVD and MOPP and were greater than those in healthy eyes. The macular RVD and MOPP showed different diurnal patterns between the two groups. From these findings, OCTA-derived RVD variation could be related to hemodynamic variability in low-teens NTG.
Polymerization of mono‐, Di‐, and trichloroethyl methacrylates: A study in chain transfer (2016)

ABSTRACT Bulk free radical polymerization of the monomer series CH 2 = C(CH 3 )C(O)OCH 2 CH 3‐ n Cl n , n = 1, 2, 3, yields an unexpectedly crosslinked product with a crosslink density that increases with decreasing chlorine content of the respective monomer ( n = 3 &lt; n = 2 &lt; n = 1). This chlorine substituent effect is investigated by correlation with chain transfer constant measurements for four homologous series of chloroalkyl compounds (chloroethyl acetates (CH 3 C(O)OCH 2 CH 3‐ n Cl n , n = 1,2,3); chloromethanes (CH 4‐ n Cl n , n = 2,3,4) and CD 2 Cl 2 and CDCl 3 analogs; butyl chloride isomers ( n‐ , iso‐ , sec ‐, tert ‐) and tert ‐C 4 D 9 Cl analog; and nine chloroethanes (C 2 H n −6 Cl n , n = 1–6)) in a methyl methacrylate polymerization. The pattern conveyed by the magnitude of chain transfer constants and deuterium isotope effects is consistent with a vicinal chlorine effect (i.e., chlorine activation of a vicinal hydrogen for abstraction) to account for the relative activities of the four series of model compounds and for the propensity of the chloroethyl methacrylates to crosslink in a bulk free radical polymerization. The chloroalkyl moiety's contribution to chain transfer is relatively modest (≤10 −4 ), but, when incorporated as a monomer pendant group in free radical polymerizations, it is effective in broadening molecular weight to the extent of resulting in a crosslinked polymer.

Syntheses of radiolabeled ABT‐578 for ADME studies (2006)

Abstract Several isotopomers of ABT‐578 ( I , II , III , and IV ) were prepared starting from different labeled precursors: [5'‐ 3 H]‐tetrazole ( 1 ), [5'‐ 14 C]‐tetrazole ( 2 ), [40‐ 3 H]rapamycin ( 3 ), and [2,11,31‐ 3 H]rapamycin ( 4 ). It was shown that the tritium label at the 40 position of rapamycin is lost during an attempted synthesis of [40‐ 3 H]ABT‐578 ( III ). Copyright © 2006 John Wiley &amp; Sons, Ltd.
SOMSI: Spherical Novel View Synthesis with Soft Occlusion Multi-Sphere Images (2022)

Spherical novel view synthesis (SNVS) is the task of estimating 360 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">○</sup> views at dynamic novel views given a set of 360 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">○</sup> input views. Prior arts learn multi-sphere image (MSI) representations that enable fast rendering times but are only limited to modelling low-dimensional color values. Modelling high-dimensional appearance features in MSI can result in better view synthesis, but it is not feasible to represent high-dimensional features in a large number (> 64) of MSI spheres. We propose a novel MSI representation called Soft Occlusion MSI (SOMSI) that enables modelling high-dimensional appearance features in MSI while retaining the fast rendering times of a standard MSI. Our key insight is to model appearance features in a smaller set (e.g. 3) of occlusion levels instead of larger number of MSI levels. Experiments on both synthetic and real-world scenes demonstrate that using SOMSI can provide a good balance between accuracy and run-time. SOMSI can produce considerably better results compared to MSI based MODS [1], while having similar fast rendering time. SOMSI view synthesis quality is on-par with state-of-the-art NeRF [24] like model while being 2 orders of magnitude faster.

The implementation of a transient DC-link boost based digital amplifier for eliminating pulse-dropping distortion (2004)

A transient dc-link boost technique for avoiding pulse dropping in digital amplifiers is presented. The concept is based on increasing the dc link voltage and reducing the modulation index momentarily, when the modulating signal is large. Apart from effectively reducing harmonic distortion at the output, the proposed method can also widen the dynamic modulation range and thus reduce the required supply voltage. A 10 W prototype with an H-bridge inverter has been built. Some pulses are artificially dropped in the gate signals to simulate the pulse-dropping effect. The inverter output harmonic spectra with and without the transient boost have been compared.

Density saturation of densely contact-electrified negative charges on a thin silicon oxide sample due to the Coulomb repulsive force (1996)

Abstract To compare the mechanism of the contact electrification on a thin silicon oxide sample in air with that in vacuum, the contact voltage V C and contact time t 0 dependences of the peak value and the full width at half maximum (FWHM) of the electrostatic force distributions induced by the deposited negative charges just after the contact electrification were measured. In air, the peak value of the electrostatic force was found to saturate with increase in both V C and t 0. Also, the FWHM was found to increase monotonically with increase in both V c and t 0. These results suggest that density saturation of the deposited negative charges occurs and that the saturated charge density is independent of both V c, and t 0. Further, the deposited negative charges diffuse owing to the Coulomb repulsive force between the deposited negative charges. On the other hand, in vacuum, the peak value of the electrostatic force was found to saturate with increase in t 0, whereas it increases monotonically with increase in V c. Also, the FWHM of the electrostatic force was found to be nearly independent of both V C and t 0. Thus deposited negative charges do not diffuse even during contact electrification and the incessant deposition seems to be inhibited by the Coulomb repulsive force at the charge density where the Coulomb repulsive force due to the deposited negative charges equilibrates with the force for the contact electrification due to V c.
