Joint pre-stack stratigraphic inversion and facies analysis on a Brazilian deep offshore field (2003)

We present in this paper an integrated workflow to extract key parameters from seismic angle sub-stacks in a reservoir characterization purpose. The workflow consists in three main steps. First, from seismic angle sub-stacks and well log data, we use a multi-well and multi-angle calibration technique to extract one wavelet per angle sub-stack. Second, we use a joint stratigraphic inversion method to retrieve elastic parameters (density, P- and Simpedances) rom the seismic angle sub-stacks. This method is a model-based inversion, which allows to integrate a priori geological knowledge in the impedance retrieving process. To compute synthetic angle substacks from the elastic parameter model in the inversion process, we use the Aki-Richards equations, which are&lt;br&gt;linear approximations of the Knott-Zoeppritz full-wave equations. Finally, we present the methodology for a qualitative interpretation of the P- and S-impedances into seismic facies. This integrated workflow is applied to a real case-study: the interpretation of pre-stack seismic data from a Brazilian deep offshore field.
Superoxide (Electro)Chemistry on Well-Defined Surfaces in Organic Environments (2016)

Efficient chemical transformations in energy conversion and storage systems depend on understanding superoxide anion (O2–) electrochemistry at atomic and molecular levels. Here, a combination of experimental and theoretical techniques are used for rationalizing, and ultimately understanding, the complexity of superoxide anion (electro)chemistry in organic environments. By exploring the O2 + e– ↔ O2– reaction on well-characterized metal single crystals (Au, Pt, Ir), Pt single crystal modified with a single layer of graphene (Graphene@Pt(111)), and glassy carbon (GC) in 1,2 dimethoxyethane (DME) electrolytes, we demonstrate that (i) the reaction is an outer-sphere process; (ii) the reaction product O2– can “attack” any part of the DME molecule, i.e., the C–O bond via nucleophilic reaction and the C–H bond via radical hydrogen abstraction; (iii) the adsorption of carbon-based decomposition products and the extent of formation of a “solid electrolyte interface” (“SEI”) increases in the same order as the reactivity of the substrate, i.e., Pt(hkl)/Ir(hkl) ≫ Au(hkl)/GC > Gaphene@Pt(111); and (iv) the formation of the “SEI” layer leads to irreversible superoxide electrochemistry on Pt(hkl) and Ir(hkl) surfaces. We believe this fundamental insight provides a pathway for the rational design of stable organic solvents that are urgently needed for the development of a new generation of reliable and affordable battery systems.

Joint Channel Direction Information Quantization For Spatially Correlated 3D MIMO Channels (2015)

This paper proposes a codebook for jointly quantizing channel direction information (CDI) of spatially correlated three-dimensional (3D) multi-input-multi-output (MIMO) channels. To reduce the dimension for quantizing the CDI of large antenna arrays, we introduce a special structure to the codewords by using Tucker decomposition to exploit the unique features of 3D MIMO channels. Specifically, the codeword consists of four parts each with low dimension individually targeting at a different type of information: statistical CDIs in horizontal direction and in vertical direction, statistical power coupling, and instantaneous CDI. The proposed codebook avoids the redundancy led by existing independent CDI quantization. Analytical results provide a sufficient condition on 3D MIMO channels to show that the proposed codebook can achieve the same quantization performance as the well-known rotated codebook applied to the global channel CDI, but with significant reduction in the required statistical channel information. Simulation results validate our analysis and demonstrate that the proposed joint CDI quantization provides substantial performance gain over independent CDI quantization.
Exploiting the Spatial Information Provided by Channel Statistics and SNR Feedback (2006)

A major limiting factor in communication systems utilizing multi-antenna transmission is the amount of spatial channel information available at the transmitter. Since the channel realizations, in most cases, can only be estimated at the receiver, such information must be fed back to the transmitter. In multiuser systems the amount of feedback must be kept minimal, which seriously limits the information that can be fed back. Herein it is shown that the feedback of a scalar signal to noise ratio (SNR), together with knowledge of the statistical properties of the channel, provides substantial spatial information about the current channel realization. The spatial information is particularly good for strong channel realizations, i.e. for users that are candidates for scheduling. Previous results are extended to the Ricean channel model and the impact of the non-zero expected value is shown to further improve the spatial information

HIGH SPECTRAL RESOLUTION MEASUREMENT OF THE SUNYAEV–ZEL'DOVICH EFFECT NULL WITH Z-Spec (2012)

The Sunyaev-Zel'dovich (SZ) effect spectrum crosses through a null where T CMB = 0 near 0 = 217 GHz. In a cluster of galaxies, 0 can be shifted from the canonical thermal SZ effect value by corrections to the SZ effect scattering due to the properties of the inter-cluster medium. We have measured the SZ effect in the hot galaxy cluster RX J 1347.5-1145 with Z-Spec, an R 300 grating spectrometer sensitive between 185 and 305 GHz. These data comprise a high spectral resolution measurement around the null of the SZ effect and clearly exhibit the transition from negative to positive T CMB over the Z-Spec band. The SZ null position is measured to be 0 = 225.8 2.5(stat.) 1.2(sys.) GHz, which differs from the canonical null frequency by 3.0 and is evidence for modifications to the canonical thermal SZ effect shape. Assuming the measured shift in 0 is due only to relativistic corrections to the SZ spectrum, we place the limit kT e = 17.1 5.3 keV from the zero-point measurement alone. By simulating the response of the instrument to the sky, we are able to generate likelihood functions in {y 0 , T e , v pec } space. For v pec = 0 km s -1 , we measure the best-fitting SZ model to be y 0 = 4.6 +0.6 -0.9 10 -4 , T e,0 = 15.2 +12 -7.4 keV. When v pec is allowed to vary, a most probable value of v pec = +450 810 km s -1 is found.

A tunable differential duplexer in 90nm CMOS (2012)

An integrated duplexer for frequency division duplex wireless standards around 2GHz is presented. The duplexer utilizes a differential version of a planar hybrid transformer to enable wideband differential to differential and differential to common-mode isolation between the transmitter and receiver. It covers WCDMA bands I, II, III, and IX, with worst-case isolation of 60dB and 40dB at the TX and RX frequencies respectively. The duplexer with a cascaded LNA achieves a noise figure of 5.6dB, and 14dB of gain. The insertion loss in the TX path is 3.7dB. The duplexer and LNA, implemented in a 90nm CMOS process, consume 20mA and occupy an active area of 0.6mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
Direct Identification of Mixed-Metal Centers in Metal–Organic Frameworks: Cu3(BTC)2 Transmetalated with Rh2+ Ions (2020)

Raman spectroscopy was used to establish direct evidence of heterometallic metal centers in a metal-organic framework (MOF). The Cu<sub>3</sub>(BTC)<sub>2</sub> MOF HKUST-1 (BTC<sup>3-</sup> = benzenetricarboxylate) was transmetalated by heating it in a solution of RhCl<sub>3</sub> to substitute Rh<sup>2+</sup> ions for Cu<sup>2+</sup> ions in the dinuclear paddlewheel nodes of the framework. In addition to the Cu-Cu and Rh-Rh stretching modes, Raman spectra of (Cu<sub><i>x</i></sub>Rh<sub>1-<i>x</i></sub>)<sub>3</sub>(BTC)<sub>2</sub> show the Cu-Rh stretching mode, indicating that mixed-metal Cu-Rh nodes are formed after transmetalation. Density functional theory studies confirmed the assignment of a Raman peak at 285 cm<sup>-1</sup> to the Cu-Rh stretching vibration. Electron paramagnetic resonance spectroscopy experiments further supported the conclusion that Rh<sup>2+</sup> ions are substituted into the paddlewheel nodes of Cu<sub>3</sub>(BTC)<sub>2</sub> to form an isostructural heterometallic MOF, and electron microscopy studies showed that Rh and Cu are homogeneously distributed in (Cu<sub><i>x</i></sub>Rh<sub>1-<i>x</i></sub>)<sub>3</sub>(BTC)<sub>2</sub> on the nanoscale.
Expansion of the Cortical Representation of a Specific Skin Field in Primary Somatosensory Cortex by Intracortical Microstimulation (1992)

Intracortical microstimulation (ICMS) was applied to a single site in the middle cortical layers (III-IV) in the koniocortical somatosensory fields of sodium pentobarbital-anesthetized rats (Sml) and new world monkeys (area 3b). Low-threshold cutaneous receptive fields were defined in the cortical region surrounding the stimulation site prior to and following 2-6 hr of 5 microA ICMS stimulation. ICMS stimulation did not usually affect the receptive field location, size, or responsiveness to tactile stimulation of neurons at the stimulation site. However, the number of cortical neurons surrounding the stimulation site with a receptive field that overlapped with the ICMS-site receptive field increased in all studied animals, resulting in an enlarged cortical representation of a restricted skin region spanning several hundred microns. The mean size of receptive fields changed in some but not all cases. These results provide evidence that the responses of cortical neurons are subject to change by the introduction of locally coincident inputs into a single location, and demonstrate a capacity for representational plasticity in the neocortex in the absence of peripheral stimulation. These experimental observations are consistent with hypotheses that the cerebral cortex comprises radially oriented populations of neurons that share a common input, and that these inputs are shaped by coincident activity (see Edelman, 1978, 1987; Merzenich, 1987; Merzenich et al., 1990; von der Malsburg and Singer, 1988).
Virtual Training for a Manual Assembly Task (2001)

This paper describes an experiment conducted to investigate the benefits of force feedback for virtual reality training of a real task. Three groups of subjects received different levels of training before completing a manual task, the construction of a LEGO(TM) biplane model. One group trained on a Virtual Building Block (VBB) simulation, which emulated the real task in a virtual environment, including haptic feedback. A second group was also trained on the VBB system, but without the force feedback. The last group received no virtual reality training. Completion times were compared for these different groups in building the actual biplane model in the real world ANOVA analysis showed a significant change in performance due to training level.
Hybrid Bidirectional Wireless EV Charging System Tolerant to Pad Misalignment (2017)

Electric vehicles (EVs) are becoming increasingly popular as a means of future transport for sustainable living. However, wireless charging of EVs poses a number of challenges related to interoperability, safety, pad misalignment, etc. In particular, pad misalignments invariably cause changes in system parameters which in turn lead to increase in losses as well as reduction in power throughput, making the charging process long and inefficient. Consequently, wireless charging systems that are less sensitive to pad misalignments have become preferable. This paper, therefore, presents a hybrid wireless power transfer (WPT) system that charges EVs at constant rate despite large misalignments between charging pads. The proposed charging system uses a combination of two different resonant networks to realize a constant and efficient charging process. A mathematical model is also developed, showing as to how the two resonant networks can be combined to compensate for pad misalignments. To demonstrate the validity of the proposed concept as well as the accuracy of the mathematical model, theoretical performance is compared with both simulations and experimental results of a prototype 3.3 kW hybrid bidirectional WPT system. Results clearly indicate that the proposed hybrid WPT system is efficient and offers a constant charging profile over a wide range of spatial (three-dimensional) pad misalignments.
Data from Vasoactive Peptides with Angiogenesis-Regulating Activity Predict Cancer Risk in Males (2023)

&lt;div&gt;Abstract&lt;p&gt;&lt;b&gt;Background:&lt;/b&gt; Tumor development requires angiogenesis, and antiangiogenesis has been introduced in the treatment of cancer patients; however, how the cardiovascular phenotype correlates with cancer risk remains ill-defined. Here, we hypothesized that vasoactive peptides previously implicated in angiogenesis regulation predict long-term cancer risk.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Methods:&lt;/b&gt; We measured midregional proatrial natriuretic peptide (MR-proANP), proadrenomedullin (MR-proADM), and C-terminal preprovasopressin (copeptin) in fasting plasma from participants of the Malmö Diet and Cancer Study that were free from cancer prior to the baseline exam in 1991 to 1994 (1,768 males and 2,293 females). We used Cox proportional hazards models to determine the time to first cancer event in relation to baseline levels of vasoactive peptides during a median follow-up of 15 years.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Results:&lt;/b&gt; First cancer events occurred in 366 males and in 368 females. In males, one SD increase of MR-proANP, copeptin, and MR-proADM was independently related to incident cancer [HR (95% CI)] by 0.85 (0.74–0.96), &lt;i&gt;P&lt;/i&gt; = 0.012; 1.17 (1.04–1.32), &lt;i&gt;P&lt;/i&gt; = 0.009; and 1.12 (0.99–1.26), &lt;i&gt;P&lt;/i&gt; = 0.065, respectively, and a summed biomarker score identified an almost 2-fold difference in cancer risk between the top and bottom quartile (&lt;i&gt;P&lt;/i&gt; &lt; 0.001). In younger males, the biomarker score identified a more than 3-fold increase in risk between the top and bottom quartile (&lt;i&gt;P&lt;/i&gt; &lt; 0.001). Among females, we found no relationship between biomarkers and cancer incidence.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Conclusions:&lt;/b&gt; Our data suggest that vasoactive peptide biomarkers predict cancer risk in males, particularly in younger males.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Impact:&lt;/b&gt; Our findings may have implications for cancer risk prediction and present novel, potentially drug modifiable, mechanisms underlying cancer development. &lt;i&gt;Cancer Epidemiol Biomarkers Prev; 21(3); 513–22. ©2012 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;
Shape-Controlled Synthesis of Silver Nanoparticles by Pulse Sonoelectrochemical Methods (2000)

Shaped silver nanoparticles with spheres, rods, and dendrites have been prepared by a pulse sonoelectrochemical technique from an aqueous solution of AgNO3 in the presence of nitrilotriacetate N(CH2COOH)3-NTA. The silver nanoparticles were characterized by using transmission electron microscopy, X-ray diffraction, and absorption spectroscopy. The effects of electrosonic time on particle shape have been discussed. It was found that the concentration of AgNO3 and NTA affects the shape of the nanoparticles.
SIGNAL IMPROVEMENT BY DIELECTRIC FOCUSING IN MICROFLUIDIC IMPEDANCE CYTOMETERS (2010)

We report the design and the electrical and microfluidic characterization of a device that improves signal strength and increases the detection levels in microfluidic impedance cytometry. Lowconductivity aqueous and twophase dielectric sheathing allows the use of wider, more easily fabricated channels, increases the precision of cellaparticlesize measurements, and decreases the smallest detectable object size. For aqueous dielectric sheathing with a fixed excitation voltage of 400 mV rms , the highest relative signal strength measured was 1.4 ± 0.6% for a 27��m core. The use of a two� phase system and a core width of 33 �m resulted in a signal strength of 5.1 ± 0.5%. This twophase system increases SNR by 23 dB compared to the aqueous system.
Periostin as a novel biomarker for postoperative recurrence of chronic rhinosinitis with nasal polyps (2018)

We previously reported that chronic rhinosinusitis with nasal polyps (CRSwNP) was subdivided into four chronic rhinosinusitis (CRS) subtypes using the JESREC scoring system. We sought to identify the gene expression profile and biomarkers related with CRSwNP by RNA-sequence. RNA-sequencing was performed to identify differentially expressed genes between nasal polyps (NPs) and inferior turbinate mucosa from 6 patients with CRSwNP, and subsequently, quantitative real-time PCR was performed to verify the results. ELISA was performed to identify possible biomarkers for postoperative recurrence. In the RNA-sequencing results, periostin (POSTN) expression was the highest in NP. We focused on POSTN and investigated the protein level of POSTN by immunohistochemistry and ELISA. POSTN was diffusely expressed in moderate and severe eosinophilic CRS using immunohistochemistry, and its staining pattern was associated with the severity of the phenotype of the CRSwNP (P < 0.05). There was a significant difference between the POSTN high/low groups for postoperative recurrence when the cutoff point was set at 115.5 ng/ml (P = 0.0072). Our data suggests that the protein expression level of POSTN was associated with the severity of CRSwNP, and serum POSTN can be a novel biomarker for postoperative recurrence of CRSwNP.
Inherent Inability of Chronic Lymphocytic Leukaemia Lymphocytes to Respond to Phytohaemagglutinin (1972)

The leukaemic cells from chronic lymphocytic leukaemia (CLL) patients are shown to be inherently unable to respond &lt;i&gt;in vitro&lt;/i&gt; to phytohaemagglutinin (PHA). The response which occurs to PHA in CLL cultures is accounted for entirely by the small percentage of normal lymphocytes present among the leukaemic cells. The time curve of the delayed peak of DNA synthesis in PHA-stimulated CLL cultures is identical with that given by low concentrations of normal donors’ leucocytes. Morphological studies of PHA-stimulated CLL cultures and sex chromosome analysis of responding cells in PHA-stimulated cultures which contain both CLL and normal donor leucocytes confirm that the majority of lymphocytes in CLL blood do not undergo DNA synthesis or blastogenesis in response to PHA.
Azepino- and Diazepinoindoles: Synthesis and Dopamine Receptor Binding Profiles (2000)

Starting from the readily available building blocks 7, 10, 11, and 15, the synthesis of the fused indoles 1, 2, 5, and 6, respectively, is reported. The syntheses involved Pictet-Spengler cyclizations, Michael addition reactions, lactamization, directed metallation, and reductive amination as the key reaction steps. Radioligand displacement studies comprising the dopamine receptor subtypes D1, D2long D2short, D3, and D4.4 were performed when the diazepinoindole 6 revealed D1 and D4 affinities (Ki = 0.11 microM and 1.7 microM, respectively) which are comparable to the partial D1 agonist SKF 38393 (3b). In contrast to the benzazepine 3b, the indole based test compounds turned out less selective over the D2 and D3 receptor subtype.
Comparison of hot pressing and spark plasma sintering in the densification behavior of indium tin oxide‐borosilicate glass composites (2017)

Abstract The goal of this study was to fabricate borosilicate glass matrix composites with high optical transmittance and high conductivity by forming percolated segregated networks of indium tin oxide ( ITO ) in the microstructure. ITO nanoparticles and borosilicate glass microspheres were mechanically mixed with ITO concentrations varying from 0 to 2.99 vol%. The mixes were then consolidated using either hot pressing ( HP ) or spark plasma sintering ( SPS ). The effects of changing sintering methods, along with varying other processing parameters such as heating rate, maximum temperature, and applied pressure, had surprising and unanticipated effects. Ac impedance spectroscopy ( IS ), SEM , and EDS results indicated the successful formation of a grain‐like microstructure of the sintered glass using both HP and SPS processing, with the ITO particles segregated to the boundary regions in all samples. IS results indicated percolation threshold values between 0.154 and 0.307 vol% ITO in the HP samples and between 0.307 and 0.764 vol% ITO in the SPS samples, with resistivities as low as 29 (Ω·cm) at 2.99 vol% ITO . Optical properties were dominated by impurities and light scattering at defects such as pores. Contrary to conventional belief, it was found that samples made using SPS required far higher temperatures to fully densify, with all other processing conditions being the same, compared with HP . This behavior was confirmed through repeat tests using different SPS equipment and a wide range of processing conditions.
Novel Composite Anion Exchange Membranes Based on Quaternized Polyepichlorohydrin for Electromembrane Application (2016)

A series of semi-interpenetrating polymer network (sIPN) composite anion exchange membranes were fabricated depending on immobilized linear PVDF and cross-linked polyepichlorohydrin (PECH), 1,4-diazabicyclo[2.2.2]octane, (DABCO) network through in situ synthetic pathway. A cyclic diamine (DABCO) was used as cross-linking agent and simultaneously improved the ion-exchange capacity by amination. Scanning electron microscopy (SEM) indicated that the composite membranes exhibited a dense and homogeneous structure. Successful formation of PECH-DABCO copolymer within the sIPN membranes was also confirmed by Fourier transform infrared (FTIR) and X-ray photoelectron spectroscopy (XPS). The PVDF percentage and inherent properties of membranes such as ion exchange capacity (IEC), water uptake (WR), thermal stability, mechanical property, and area resistance were investigated to evaluate their applicability in electrodialysis (ED). The experimental results showed that the composite membrane maintained a good perspective for ED application.
