A New Wireless Power Transmission (WPT) System for Powering Wireless Sensor Networks (WSNs) in Cavity-Based Equipment (2019)

We introduce a new cavity-based wireless power transmission (WPT) system that could be applied to any cavity-based equipment regardless of its shape and size. The proposed scheme provides uniform and selective powering modes. In either powering mode, the field is isotropic, which removes the WPT-restrictions on placement and orientation of the energy harvester. The design process has three main steps, randomness creation, frequency selection, and waveform generation. We validate the proposed scheme in a lab lyophiliser's (freeze-drier) chamber. First, we create a random electromagnetic environment using mechanical stirring. Then, we evaluate this randomness in terms of the average to minimum power ratio. To select an appropriate frequency for the WPT system, we consider randomness and power uniformity. To maintain randomness, we extract the lowest usable frequency of the chamber using a Goodness of Fit test; this is found to be 6 GHz. As for the power uniformity, we plot the standard deviation (STD) of a large sample of the received powers at different locations. This plot is used to select the frequency based on an arbitrary uniformity level in terms of STD. At 6 GHz a 2.5 dB standard deviation is calculated. To enable the selective powering mode, we propose the electromagnetic time reversal (EMTR) technique. We show that EMTR can, theoretically, focus 97% of the energy on 0.5λ-diameter area in an ideally random environment.
Partial motion blending and assembly for interactive motion synthesis (2008)

Interactively controlling or editing motion capture data is an intriguing topic in games or animation prototyping.\nHowever, data-driven approaches require a large data set to synthesize motion of high variety. In the first part of\nthis paper, we propose novel partial motion synthesis to extend the control parameter space or variety of limited\nmotion data. We extend the attack range of kicking or punching by blending body parts respectively and then\nreassembling. Users can simply assign a target position in the extended parameter space and will get a motion\nthat hit the desired target. In the second application, we propose applying partial motion assembly for motion\nediting. Given a sequence of key postures, our system will retrieve resembling partial figures from data sets.\nWhile reassembling the different parts of character motion and adjusting the motion variance according to the\nquery motion, our novel synthetic motions can preserve original style and naturalness.
Expression and cellular localization of naturally occurring β estrogen receptors in uterine and mammary cell lines (2002)

The protein ER-alpha has been exhaustively characterized in estrogen-sensitive tissues and cell lines. However, little is known regarding the expression and cellular distribution of the newly identified ER-beta protein. We first quantified the specific estradiol binding site content in the estrogen-responsive cell lines MCF-7 (mammary) and SHM (myometrial). In the two cell types, these sites were associated to the expression of both ER-alpha and -beta isoforms. Native ER-beta was visualized to reside inside the nucleus by means of conventional indirect immunofluorescence. The cells expressed ER-beta as a tight approximately 50 kDa triplet when resolved by sodium dodecyl sulfate-polyacrylamide gels (SDS-PAGE) and blotted using antibodies mapping different domains of the cloned ER-beta version. When the cells were subjected to homogenization and differential centrifugation, a substantial proportion of ER-beta immunolabeling was localized at membrane subfractions. ER-beta expression and partitioning was confirmed by Ligand blotting assays using estrogen derivatives coupled to different macromolecular tags. However, ER-alpha was expressed as the major estrogen binding protein in both cell lines. Similar localization experiments were performed on HeLa cells (cervix). Though usually considered ER-negative, this cell line displayed basal significant estrogen binding capacity and co-expression of both ER isoforms. Taken as a whole, the results indicate that ER-beta could be expressed as functional estrogen binding proteins among a dominant population of ER-alpha sites in the cell lines under study.
A case-control study of healthcare disparities in sex and gender minority patients with breast cancer. (2022)

6517 Background: Disparities in the quality of diagnosis and treatment of breast cancer in sex and gender minority (SGM) populations are largely undefined. Only 24% of studies funded by the National Cancer Institute capture data on sexual orientation, while only 10% capture data on gender identity. To address this gap, the National Academies 2020 Report calls for adding sexual orientation and gender identity (SOGI) to ongoing data collection efforts. This case-control study matching SGM patients with breast cancer to cisgender heterosexual controls is the result of linking SOGI data to the Stanford University Healthcare (SHC) Oncoshare breast cancer database, which integrates data from the electronic medical record (EMR) and California Cancer Registry. Methods: An initial database query across the SHC EMR was performed for charts containing SOGI terms in patients with breast cancer seen in SHC Oncology. 686 charts were identified for manual review and after eliminating false positives, the sample was reduced to 92 SGM patients, who were then matched by year of diagnosis, age, stage, ER-status, and HER-2 status to cisgender heterosexual controls within Oncoshare. Additional data on demographics, diagnosis, treatment, and relapse were then manually abstracted from the EMR. Results: The SGM cohort was comprised of 80% lesbians, 13% bisexuals and 6% transgender men. The median age at diagnosis across both groups was 49. SGM patients were 72% white, 4% Asian, 12% Black or Latinx 6% other compared to 63% white, 24% Asian, 6% Black or Latinx, 6% other in the controls (p = 0.0006). Thirteen percent and 32% of SGM patients engaged in risky alcohol and illicit drug use respectively, compared to 3% and 6% of controls (p = 0.028; p &lt; 0.0001). Estrogen exposure risk factors including median age of menarche, first delivery, menopause, and use of exogenous estrogens were balanced between the two groups, but SGM patients had fewer children (median 0 vs 2, p &lt; 0.0001). There was a delay in time to diagnosis from symptom onset in SGM patients versus controls (median 64 days vs 37 days, p = 0.043). There was no difference in surgical approach, use of post-lumpectomy radiation, or use of neoadjuvant chemotherapy for stage III disease. However, SGM patients were less likely to undergo chest reconstruction (55% vs 82%, p = 0.0098) and if ER+, to complete ≥5 years of ER-directed therapy (53% vs 72%, p = 0.048). SGM patients used more alternative medicine (46% vs 29%, p = 0.033) and had a higher rate of documented refusal of recommended oncologic treatments (38% vs 21%, p = 0.0088). Correspondingly, SGM patients experienced a higher recurrence rate (31% vs 14%, p = 0.0124). Conclusions: To our knowledge, this is the first study to examine quality of diagnosis and treatment of breast cancer in SGM patients. Several novel potential healthcare disparities are identified, which should be further evaluated in population-based studies to inform interventions.

Leakage mechanism of Ba0.8Sr0.2TiO3/ZrO2 multilayer thin films (2010)

The temperature and field dependence of the I-V characteristics of Ba0.8Sr0.2TiO3 thin films and Ba0.8Sr0.2TiO3/ZrO2 multilayer thin films on Pt/Ti/SiO2/Si substrates are studied in the temperature range from 310 to 410 K. Leakage current behaviors of the film is analyzed in the light of various models. The bulk limited Poole–Frenkel mechanism is observed to dominate the leakage current in the temperature range of 310–410 K in the high field region. The energy of the trap levels calculated from the Poole–Frenkel model is in the range of 0.2–1.31 eV for different structures. In the low electric field region the conduction is Ohmic where as space charge limited current conduction is the dominant mechanism in the intermediate electric field region for all the temperatures.
Functional cooperation of the glycine synthase-reductase and Wood–Ljungdahl pathways for autotrophic growth of <i>Clostridium drakei</i> (2020)

Among CO<sub>2</sub>-fixing metabolic pathways in nature, the linear Wood-Ljungdahl pathway (WLP) in phylogenetically diverse acetate-forming acetogens comprises the most energetically efficient pathway, requires the least number of reactions, and converts CO<sub>2</sub> to formate and then into acetyl-CoA. Despite two genes encoding glycine synthase being well-conserved in WLP gene clusters, the functional role of glycine synthase under autotrophic growth conditions has remained uncertain. Here, using the reconstructed genome-scale metabolic model <i>i</i>SL771 based on the completed genome sequence, transcriptomics, <sup>13</sup>C isotope-based metabolite-tracing experiments, biochemical assays, and heterologous expression of the pathway in another acetogen, we discovered that the WLP and the glycine synthase pathway are functionally interconnected to fix CO<sub>2</sub>, subsequently converting CO<sub>2</sub> into acetyl-CoA, acetyl-phosphate, and serine. Moreover, the functional cooperation of the pathways enhances CO<sub>2</sub> consumption and cellular growth rates via bypassing reducing power required reactions for cellular metabolism during autotrophic growth of acetogens.
Toward a Computer Assisted Analysis of NOESY Spectra: A Multivariate Data Analysis of an RNA NOESY Spectrum (1989)

A multivariate data-representation of a portion of the H-NOESY spectrum of an RNA octamer duplex was used to explore the possibility of using Principal Component Analysis and Partial Least Squares Discrimination for pattern recognition. In this case, it is found that the methods can: (i) distinguish slices containing signal from those containing only noise, (ii) locate slices containing overlapping signals, and (iii) in some cases to segregate slices with unique aspects such as those from terminal nucleotides, overlapping signals, purine-H8, pyrimidine-H6 and adenine-H2 containing slices. These properties can easily be included in a scheme to automate spectral analysis. The formulation described here does not distinguish patterns needed to automate sequential assignment of resonances in NOESY spectra of RNA.

Control of Electron Localization in Molecular Dissociation (2006)

We demonstrated how the subcycle evolution of the electric field of light can be used to control the motion of bound electrons. Results are presented for the dissociative ionization of deuterium molecules (D2 --> D+ + D), where asymmetric ejection of the ionic fragment reveals that light-driven intramolecular electronic motion before dissociation localizes the electron on one of the two D+ ions in a controlled way. The results extend subfemtosecond electron control to molecules and provide evidence of its usefulness in controlling reaction dynamics.
Abstract 2528: Enhanced sensitivity of pancreatic cancer cells to the concurrent inhibition of aberrant Stat3 and EGFR or Src (2010)

Abstract Pancreatic cancer is a lethal disease with little understanding of the etiology and no effective therapies. While aberrant epidermal growth factor receptor (EGFR), Src and Stat3 are detected in pancreatic cancer and implicated in the disease, their exact roles in the support of the disease phenotype remain poorly defined. Moreover, the potential for a cross-talk between EGFR, Src and Stat3 poses a challenge to any therapy that targets only one of these entities. In this study, we sought to define the EGFR, Src and Stat3 signaling integration and to investigate the contributory roles of the three entities to the pancreatic cancer phenotype. We found in Panc-1 and Colo-357 lines that phospho-Y845EGFR, pY1068EGFR and pY1086EGFR levels are responsive to c-Src inhibition, in contrast to pY1173EGFR that is solely EGFR kinase-dependent. Treatment of Panc-1 and Colo-357 cells with the EGFR inhibitor, Iressa (ZD 1839) or the Src inhibitor, Dasatinib (Das) suppressed the constitutively-active Stat3 activity, suggesting that both EGFR and Src activities promote aberrant Stat3 activation in pancreatic cancer cells. However, the early suppression of aberrantly-active Stat3 by the EGFR and Src inhibition in Panc-1 cells is countered by a Janus kinase (Jaks)-dependent re-activation, suggesting that Jaks activity could represent a compensatory mechanism for Stat3 induction. The abrogation of c-Src activity by either Das treatment or the over-expression of a kinase-dead c-Src mutant suppressed the levels of phospho-FAK, phospho-p130Cas, phospho-cortactin, phospho-p120catenin, and phospho-paxillin, suggesting that Src activity induces the mediators of motility and migration in pancreatic cancer cells. By contrast, neither EGFR nor Src inhibition modulated the baseline enhanced phospho-ErkMAPK or phospho-Akt levels in Panc-1 and Colo-357 cells, consistent with the observation that the inhibition of EGFR or Src alone only weakly suppressed cell growth and survival of pancreatic cancer cells. By contrast, the concurrent inhibition of Stat3 and EGFR or Src induced greater viability loss and apoptosis, and diminished the migration/invasion of pancreatic cancer cells in vitro. Of therapeutic significance, the concurrent inhibition of Stat3 and EGFR or Src, as compared to mono-targeting modality, induced a stronger human pancreatic tumor growth inhibition in xenografts models. We infer that the large tumor growth inhibition in vivo is due to the simultaneous suppression of the abnormal functions of Stat3 and EGFR or Src. These studies strongly suggest that the concurrent targeting of Stat3 and EGFR or Src could be a beneficial therapeutic approach for pancreatic cancer.

Pose Guided Attention for Multi-Label Fashion Image Classification (2019)

We propose a compact framework with guided attention for multi-label classification in the fashion domain. Our visual semantic attention model (VSAM) is supervised by automatic pose extraction creating a discriminative feature space. VSAM outperforms the state of the art for an in-house dataset and performs on pair with previous works on the DeepFashion dataset, even without using any landmark annotations. Additionally, we show that our semantic attention module brings robustness to large quantities of wrong annotations and provides more interpretable results.
Calcium Carbonate Packed Electrochemical Precipitation Column: New Concept of Phosphate Removal and Recovery (2019)

Phosphorus (P) is a vital micronutrient element for all life forms. Typically, P can be extracted from phosphate rock. Unfortunately, the phosphate rock is a nonrenewable resource with a limited reserve on the earth. High levels of P discharged to water bodies lead to eutrophication. Therefore, P needs to be removed and is preferably recovered as an additional P source. A possible way to achieve this goal is by electrochemically induced phosphate precipitation with coexisting calcium ions. Here, we report a new concept of phosphate removal and recovery, namely a CaCO<sub>3</sub> packed electrochemical precipitation column, which achieved improved removal efficiency, shortened hydraulic retention time, and substantially enhanced stability, compared with our previous electrochemical system. The concept is based on the introduction of CaCO<sub>3</sub> particles, which facilitates calcium phosphate precipitation by buffering the formed H<sup>+</sup> at the anode, releases Ca<sup>2+</sup>, acts as seeds, and establishes a high pH environment in the bulk solution in addition to that in the vicinity of the cathode. It was found that the applied current, the CaCO<sub>3</sub> particle size, and the feed rate affect the removal of phosphate. Under optimized conditions (particle size, <0.5 mm; feed rate, 0.4 L/d; current, 5 mA), in a continuous flow system, the CaCO<sub>3</sub> packed electrochemical precipitation column achieved 90 ± 5% removal of phosphate in 40 days and >50% removal over 125 days with little maintenance. The specific energy consumptions of this system lie between 29 and 61 kWh/kg P. The experimental results demonstrate the promising potential of the CaCO<sub>3</sub> packed electrochemical precipitation column for P removal and recovery from P-containing streams.
Surface-Enhanced Vibrational Spectroscopy of Adsorbates on Microemulsion Synthesized Gold Nanoparticles (2011)

Very small (<10 nm) monodisperse gold nanoparticles (AuNPs) coated with a monolayer of decanethiol were prepared and their surface-enhanced infrared absorption (SEIRA) spectra were measured in the transmission mode. The AuNPs were prepared by the borohydride reduction of HAuCl(4) inside reverse micelles that were made by adding water to a hexane solution of sodium bis(2-ethylhexyl)sulfosuccinate (AOT). The gold nanoparticles were then stabilized by the addition of decanethiol. Subsequent addition of p-nitrothiophenol both facilitated the removal of excess AOT and showed that the gold surface was completely covered by the decanethiol. SEIRA spectra of decanethiol on gold particles prepared in AOT microemulsions were about twelve times more intense than corresponding layers on gold produced by electroless deposition and gave a significantly less noisy spectrum compared to the corresponding surface-enhanced Raman spectrum. The surface-enhanced Raman scattering (SERS) spectra of the same samples showed that the most intense spectrum was obtained from gold nanoparticles with a mean diameter of 2.5 nm. This result is in contrast to previous statements that SERS spectra could only be obtained from particles larger than 10 nm.
Fourier transform mass spectrometry—advancing years (1992-mid. 1996) (1996)

This article is one of a series of Fourier transform mass spectrometry (FTMS) reviews that has appeared in this journal at ca. 3-4 year intervals. A comprehensive review of the recent theoretical developments, instrumental developments, electrospray ionization (ESI), and MALDI is given. Ion dissociation techniques are also discussed because of their contributions to gaining insight into chemical structure. Special sections have been devoted to discussing the emerging fields of surface analysis, polymer analysis, Buckminsterfullerenes (buckyballs), and hydrogen/deuterium exchange studies. This review, although not all-inclusive, is intended to be a starting point for those wishing to learn more about the current status of FTMS, and also as a representative cross-section of the literature for those familiar with the technique. © 1997 John Wiley & Sons, Inc.
General Crease Patterns (2007)

Our knowledge about single-vertex flat foldability from Section 12.2 (p. 198) allows us to solve a more general problem involving local foldability of vertices in a general crease pattern (on a flat piece of paper). A vertex in a crease pattern or mountain–valley pattern is locally flat foldable if we obtain flat foldability when we cut out any region containing the vertex, portions of its incident edges, and no other vertices or edges. We can make the canonical choice for the cut-out region of a small disk centered at the vertex. Thus local flat foldability of a vertex is equivalent to single-vertex foldability in a crease pattern or mountain–valley pattern obtained by restricting the larger pattern to the creases incident to the vertex.
Cyp2j5-Gene Deletion Affects on Acetylcholine and Adenosine-Induced Relaxation in Mice: Role of Angiotensin-II and CYP-Epoxygenase Inhibitor (2020)

Previously, we showed vascular endothelial overexpression of human-CYP2J2 enhances coronary reactive hyperemia in Tie2-CYP2J2 Tr mice, and eNOS<sup>-/-</sup> mice had overexpression of CYP2J-epoxygenase with adenosine A<sub>2A</sub> receptor-induced enhance relaxation, but we did not see the response in CYP2J-epoxygenase knockout mice. Therefore, we hypothesized that <i>Cyp2j5</i>-gene deletion affects acetylcholine- and 5'-N-ethylcarboxamidoadenosine (NECA) (adenosine)-induced relaxation and their response is partially inhibited by angiotensin-II (Ang-II) in mice. Acetylcholine (Ach)-induced response was tested with <i>N</i>-(methylsulfonyl)-2-(2-propynyloxy)-benzenehexanamide (MS-PPOH, CYP-epoxygenase inhibitor; 10<sup>-5</sup>M) and Ang-II (10<sup>-6</sup>M). In <i>Cyp2j5<sup>-/-</sup></i> mice, ACh-induced relaxation was different from C57Bl/6 mice, at 10<sup>-5</sup> M (76.1 ± 3.3 <i>vs.</i> 58.3 ± 5.2, <i>P</i> < 0.05). However, ACh-induced relaxation was not blocked by MS-PPOH in <i>Cyp2j5<sup>-/-</sup></i> : 58.5 ± 5.0%, <i>P</i> > 0.05, but blocked in C57Bl/6: 52.3 ± 7.5%, <i>P</i> < 0.05, and Ang-II reduces ACh-induced relaxation in both <i>Cyp2j5<sup>-/-</sup></i> and C57Bl/6 mice (38.8 ± 3.9% and 45.9 ± 7.8, <i>P <</i>0.05). In addition, NECA-induced response was tested with Ang-II. In <i>Cyp2j5<sup>-/-</sup></i> mice, NECA-induced response was not different from C57Bl/6 mice at 10<sup>-5</sup>M (23.1 ± 2.1 <i>vs.</i> 21.1 ± 3.8, <i>P</i> > 0.05). However, NECA-induced response was reduced by Ang-II in both <i>Cyp2j5<sup>-/-</sup></i> and C57Bl/6 mice (-10.8 ± 2.3% and 3.2 ± 2.7, <i>P <</i> 0.05). Data suggest that ACh-induced relaxation in <i>Cyp2j5<sup>-/-</sup></i> mice depends on nitric oxide (NO) but not CYP-epoxygenases, and the NECA-induced different response in male <i>vs.</i> female <i>Cyp2j5<sup>-/-</sup></i> mice when Ang-II treated.
Superspreading and Drying of Trisiloxane-Laden Quantum Dot Nanofluids on Hydrophobic Surfaces (2020)

Nanofluids hold promise for a wide range of areas of industry. However, understanding the wetting behavior and deposition formation in the course of drying and spreading of nanofluids, particularly containing surfactants, is still poor. In this paper, the evaporation dynamics of quantum dot-based nanofluids and evaporation-driven self-assembly in nanocolloidal suspensions on hexamethyldisilazane-, polystyrene-, and polypropylene-coated hydrophobic surfaces have been studied experimentally. Moreover, for the very first time, we make a step toward understanding the wetting dynamics of superspreader surfactant-laden nanofluids. It was revealed that drying of surfactant-free quantum dot nanofluids in contrast to pure liquids undergoes not three but four evaporation modes including last additional pinning mode when the contact angle decreases while the triple contact line is pinned by the nanocrystals. In contrast to previous studies, it was found out that addition of nanoparticles to aqueous surfactant solutions leads to deterioration of the spreading rate and to formation of a double coffee ring. For all surfaces examined, superspreading in the presence and absence of quantum dot nanoparticles takes place. Despite the formation of coffee rings on all substrates, they have different morphologies. In particular, the knot-like structures are incorporated into the ring on hexamethyldisilazane- and polystyrene-coated surfaces.
