Evaluation of a delta-connection of three single-phase unity power factor rectifier modules (±-rectifier) in comparison to a direct three-phase rectifier realization (2001)

In this paper, the voltage and current stress of a delta-connection of three single-phase boost-type unity power factor rectifier modules (Δ-Rectifier) is analyzed in order to perform a design comparable to a direct three-phase three-level six-switch unity power factor (conventional) rectifier system. The conduction losses of the power semiconductors are calculated using analytical approximations of the average and RMS values of the component currents, the switching losses are taken from previous experimental investigations. Based on this data an overview of the estimated power losses is given for the Δ-rectifier as well as for the conventional rectifier for 10 kW output power, 800 VDC output and 320 V/400 V/480 V/530 V (RMS, line-to-line) mains voltage. These investigations finally lead to efficiency and component count figures. Furthermore, special attention is paid to the control of the whole three-phase system, including the DC/DC converter output stages of the line-to-line modules of the Δ-rectifier. Finally, topics of the continuation of the research are identified as, e.g., the realization of a prototype in order to verify the theoretical results experimentally also for unbalanced mains voltage conditions and with nonideal components such as nonlinear input inductors employing iron powder cores and the analysis of a Δ-rectifier being formed by single-stage SEPIC-type line-to-line modules.
A Three-port Flyback for PV Microinverter Applications With Power Pulsation Decoupling Capability (2012)

A novel single-stage photovoltaic (PV) microinverter with power decoupling capability is proposed in this paper. The proposed topology is based on three-port flyback with one port dedicated to power decoupling function so as to reduce the decoupling capacitance, thus allowing for long lifetime film capacitor to be used. Operation principle is analyzed in details. Key design considerations, including key parameter selections, predictive control strategy, and the dc voltage balance control across the power decoupling capacitor, are given in this paper. A 100-W microinverter prototype is built to verify the proposed topology. Experimental results show the proposed topology can achieve power decoupling, while maintaining good efficiency.

Mechanism of CIT-6 and VPI-8 Crystallization from Zincosilicate Gels (2002)

The crystallisation of CIT-6, a large-pore zincosilicate with the framework topology of zeolite Beta and synthesised from clear hydrogels that contain, tetraethylammonium (TEA+), Li+ and Zn2+ cations, proceeds initially through the formation of an amorphous solid that incorporates all the initial Zn species. Nucleation of the *BEA phase is effected by reorganisation of the amorphous phase, whereas crystal growth involves the incorporation of soluble species also. A highly crystalline CIT-6 material is obtained after 164 h of synthesis at 140 degrees C. Scanning electron microscopy (SEM) shows that this sample exhibits two different types of crystals: well-defined pseudo-cubic crystals and rounded crystals. The latter has a broad crystal-size distribution. If crystallisation is continued with longer synthesis times, the VPI-8 crystalline phase appears, and a new population of needle-shaped crystals is detected in the SEM images. This new crystalline phase is nucleated on the surface of the rounded CIT-6 crystals, which disappear as the crystallisation progresses, while no changes are observed in the population of pseudo-cubic CIT-6 crystals. At higher crystallisation temperatures these phase transformations are accelerated, and the formation of VPI-8 is favoured over that of CIT-6.
Lifestyle chemistries from phones for individual profiling (2016)

Imagine a scenario where personal belongings such as pens, keys, phones, or handbags are found at an investigative site. It is often valuable to the investigative team that is trying to trace back the belongings to an individual to understand their personal habits, even when DNA evidence is also available. Here, we develop an approach to translate chemistries recovered from personal objects such as phones into a lifestyle sketch of the owner, using mass spectrometry and informatics approaches. Our results show that phones' chemistries reflect a personalized lifestyle profile. The collective repertoire of molecules found on these objects provides a sketch of the lifestyle of an individual by highlighting the type of hygiene/beauty products the person uses, diet, medical status, and even the location where this person may have been. These findings introduce an additional form of trace evidence from skin-associated lifestyle chemicals found on personal belongings. Such information could help a criminal investigator narrowing down the owner of an object found at a crime scene, such as a suspect or missing person.

Ultrastructure of cellular components of human trophoblasts during early pregnancy (1995)

Two cell types, the cyto- and syncytio-trophoblasts, were identified in human chorionic villi of 6-10 weeks' gestation. The intracellular organization of these cells was examined. Ultrathin sections of small pieces of chorionic villi revealed the presence of a multinucleate syncytiotrophoblastic layer, whose surface was covered with microvilli. The cytotrophoblasts, however, had a single large nucleus with a prominent nucleolus. An interesting feature of the basement membrane of these cells was the presence of aggregates of dark granules in samples of the earlier gestational age (6-8 weeks) and granular bodies having a dense outer ring and a translucent inner ring with a lucid central area in samples of 8-10 weeks' gestation. Both types of granules are mineralized and are assumed to perform a buffering role for maintaining the neutrality of the layer.
Tip-Enhanced Strong Coupling of Quantum Dot Single Photon Emitters (2021)

We demonstrate room temperature strong coupling of a single quantum emitter to a configurable plasmonic pico-cavity formed by a nano-tip. Through atomic scale control of mode volume we demonstrate switching and modulation of coupling strength.
Milvexian, an orally bioavailable, small‐molecule, reversible, direct inhibitor of factor XIa: In vitro studies and in vivo evaluation in experimental thrombosis in rabbits (2021)

Milvexian is an effective antithrombotic agent with limited impact on hemostasis, even when combined with aspirin in rabbits. This study supports inhibition of FXIa with milvexian as a promising antithrombotic therapy with a wide therapeutic window.
Chameleon-like elastomers with molecularly encoded strain-adaptive stiffening and coloration (2018)

Active camouflage is widely recognized as a soft-tissue feature, and yet the ability to integrate adaptive coloration and tissuelike mechanical properties into synthetic materials remains elusive. We provide a solution to this problem by uniting these functions in moldable elastomers through the self-assembly of linear-bottlebrush-linear triblock copolymers. Microphase separation of the architecturally distinct blocks results in physically cross-linked networks that display vibrant color, extreme softness, and intense strain stiffening on par with that of skin tissue. Each of these functional properties is regulated by the structure of one macromolecule, without the need for chemical cross-linking or additives. These materials remain stable under conditions characteristic of internal bodily environments and under ambient conditions, neither swelling in bodily fluids nor drying when exposed to air.
The Science of Electronics in Extreme Electromagnetic Environments I - Enclosure Coupling (2021)

This AFOSR Center of Excellence established in 2015 has been studying the science of electronics in extreme electromagnetic environments. This presentation focuses on advancing computational electromagnetic techniques for statistical and deterministic extreme electromagnetic interference (EEMI) modeling; on EEMI interactions within wave chaotic enclosures; and with EEMI interactions in networked complex enclosures. A companion presentation discusses EEMI effects on elemental CMOS devices, electro-optic devices, mathematical frameworks for modeling EEMI effects on digital logic circuits, and modeling EEMI effects on software execution.
Control of reflection at an optical interface in the absence of total internal reflection for a retroreflective display application (2006)

Reflection at an interface between two materials can be modulated by means of varying the optical properties at the interface. We have studied this modulation of the reflected light with an aim to develop a flashing retroreflector for roadside conspicuity applications. Reflectance modulation has previously been studied under the conditions of total internal reflection (TIR), where a light-absorbing material placed in the associated evanescent wave region can be used to attenuate the intensity of the reflected light. If instead the light rays strike the interface at an angle that is slightly smaller than the critical angle required for TIR, they instead undergo a substantial, but partial, reflection. We have demonstrated that an analogous attenuation effect to the TIR situation is observed, even though there is no evanescent wave present under these circumstances. We have studied this behavior and have developed a model to describe the motion of the absorbing material and the related interference effects that occur.

The Use of Graphite to Improve the Stability of Saudi Class G Oil-Well Cement against the Carbonation Process (2022)

Oil-well cement physical characteristics considerably change after being carbonated by a CO<sub>2</sub>-rich solution. In this study, the influence of graphite particles in the characteristics of oil-well cement reacted with a CO<sub>2</sub>-rich solution at 130 °C and 10 MPa for 10 days was studied. After 10 days of carbonation, incorporating 0.2% by weight of cement (BWOC) of graphite into the cement slurry decreased the carbonation depth by 29.8% as confirmed by the direct measurement and the micro-computerized tomography scan technique. The addition of 0.2% BWOC of graphite also reduced the cement matrix permeability by 31.4% and increased its compressive strength by 16.4% and tensile strength by 23.8% compared to the sample without graphite. The decrease in the cement matrix portlandite concentration and permeability of the samples prepared with graphite contributed to promote the cement matrix carbonation resistance. The microscopic images also proved that the incorporation of graphite delayed the leaching of calcium carbonate, and this is also attributed to decreasing the cement strength deterioration.
Synergistic Actions of Hematopoietic and Mesenchymal Stem/Progenitor Cells in Vascularizing Bioengineered Tissues (2008)

Poor angiogenesis is a major road block for tissue repair. The regeneration of virtually all tissues is limited by angiogenesis, given the diffusion of nutrients, oxygen, and waste products is limited to a few hundred micrometers. We postulated that co-transplantation of hematopoietic and mesenchymal stem/progenitor cells improves angiogenesis of tissue repair and hence the outcome of regeneration. In this study, we tested this hypothesis by using bone as a model whose regeneration is impaired unless it is vascularized. Hematopoietic stem/progenitor cells (HSCs) and mesenchymal stem/progenitor cells (MSCs) were isolated from each of three healthy human bone marrow samples and reconstituted in a porous scaffold. MSCs were seeded in micropores of 3D calcium phosphate (CP) scaffolds, followed by infusion of gel-suspended CD34(+) hematopoietic cells. Co-transplantation of CD34(+) HSCs and CD34(-) MSCs in microporous CP scaffolds subcutaneously in the dorsum of immunocompromised mice yielded vascularized tissue. The average vascular number of co-transplanted CD34(+) and MSC scaffolds was substantially greater than MSC transplantation alone. Human osteocalcin was expressed in the micropores of CP scaffolds and was significantly increased upon co-transplantation of MSCs and CD34(+) cells. Human nuclear staining revealed the engraftment of transplanted human cells in vascular endothelium upon co-transplantation of MSCs and CD34(+) cells. Based on additional in vitro results of endothelial differentiation of CD34(+) cells by vascular endothelial growth factor (VEGF), we adsorbed VEGF with co-transplanted CD34(+) and MSCs in the microporous CP scaffolds in vivo, and discovered that vascular number and diameter further increased, likely owing to the promotion of endothelial differentiation of CD34(+) cells by VEGF. Together, co-transplantation of hematopoietic and mesenchymal stem/progenitor cells may improve the regeneration of vascular dependent tissues such as bone, adipose, muscle and dermal grafts, and may have implications in the regeneration of internal organs.
Investigation of the correlation between the bulk and surface sensing performance in plasmonic crystals (2014)

In the investigation of the sensing performance based on localized surface plasmon resonance (LSPR), the bulk sensitivity, which is the spectral shift per refractive index unit upon the change of the surrounding index to spatial infinite, is often measured and considered as the indication of the sensing ability. To the contrary, in biosensing applications only the refractive index in a confined region close to the metal nanostructure surface is altered due to the attachment of the recognition and target molecules. The correlation between the bulk and surface sensitivity is nevertheless ambiguous, especially in strongly coupled plasmonic systems, and rarely discussed in the literature. In this paper, we examine the bulk and surface sensing performance of periodic Au nanodisk arrays on quartz substrates. By means of diffractive coupling of LSPR in the periodic arrays, the bulk sensitivity and the figure of merit (FoM, as high as ~30) could be varied by engineering the coupling strength and adjusting the size of the Au nanodisk and the array pitch. The surface sensing performance is also explored by sequential atomic layer deposition of Al2O3, and the electric field decay from the Au nanodisk surface could thus be extracted using an exponential function. It is demonstrated that in these substrates the surface and bulk sensitivity have an opposite dependence on the coupling strength. In spite of the high bulk sensitivity and FoM in systems with strong coupling, a low surface sensitivity is demonstrated due to the large electric field decay length. Therefore, detailed and careful design of the coupling strength and the surface electric field to match the size of the target biomolecule is very critical for the best sensing performance. Moreover, we provide a more reliable biosensor design protocol based on the surface sensing performance.
Depletion and enhancement mode In0.53Ga0.47As/InP junction field-effect transistor with a p+-InGaAs confinement layer (1985)

A self-aligned all-In0.53Ga0.47 As junction field-effect transistor structure grown by molecular beam epitaxy is described, using p+-InGaAs as the confinement layer for the n channel. Devices have been made to operate in either the depletion mode or the enhancement mode. Transconductances of 90 mS/mm have been observed, with low capacitance (0.7 pF/mm) and low gate leakage.
Intra Prediction and Mode Coding in VVC (2021)

This paper presents the intra prediction and mode coding of the Versatile Video Coding (VVC) standard. This standard was collaboratively developed by the Joint Video Experts Team (JVET). It follows the traditional architecture of a hybrid block-based codec that was also the basis of previous standards. Almost all intra prediction features of VVC either contain substantial modifications in comparison with its predecessor H.265/HEVC or were newly added. The key aspects of these tools are the following: 65 angular intra prediction modes with block shape-adaptive directions and 4-tap interpolation filters are supported as well as the DC and Planar mode, Position Dependent Prediction Combination is applied for most of these modes, Multiple Reference Line Prediction can be used, an intra block can be further subdivided by the Intra Subpartition mode, Matrix-based Intra Prediction is supported, and the chroma prediction signal can be generated by the Cross Component Linear Model method. Finally, the intra prediction mode in VVC is coded separately for luma and chroma. Here, a Most Probable Mode list containing six modes is applied for luma. The individual compression performance of tools is reported in this paper. For the full VVC intra codec, a bitrate saving of 25% on average is reported over H.265/HEVC using an objective metric. Significant subjective benefits are illustrated with specific examples.
Variable sensitivity photodetector for optical neural networks (1991)

A novel type of photodetector called a variable sensitivity photodetector (VSPD) has been developed for an optical implementation of a neural network. The function of the VSPD is a photodetector with functions of both a spatial light modulator and a photodetector. The VSPD with a metal-semiconductor-metal structure is shown to be suitable for the implementation of the analog synaptic weight with a bipolar value. A two-dimensional 8*8 array of VSPDs was fabricated on a GaAs substrate and integrated with a light-emitting-diode array with eight lines in hybrid form. This chip can simulate an eight-neuron system with 64 variable synaptic connections. The application to pattern classification was demonstrated by using the chip. The chip was used to classify 12 patterns into three categories by the backpropagation learning algorithm in a three-layered network. The authors studied how the nonlinear and nonuniform characteristics of the VSPD array device affect the learning performance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Clinical Protocol for a Longitudinal Cohort Study Employing Systems Biology to Identify Markers of Vaccine Immunogenicity in Newborn Infants in The Gambia and Papua New Guinea (2020)

<b>Background:</b> Infection contributes to significant morbidity and mortality particularly in the very young and in low- and middle-income countries. While vaccines are a highly cost-effective tool against infectious disease little is known regarding the cellular and molecular pathways by which vaccines induce protection at an early age. Immunity is distinct in early life and greater precision is required in our understanding of mechanisms of early life protection to inform development of new pediatric vaccines. <b>Methods and Analysis:</b> We will apply transcriptomic, proteomic, metabolomic, multiplex cytokine/chemokine, adenosine deaminase, and flow cytometry immune cell phenotyping to delineate early cellular and molecular signatures that correspond to vaccine immunogenicity. This approach will be applied to a neonatal cohort in The Gambia (<i>N</i> ~ 720) receiving at birth: (1) Hepatitis B (HepB) vaccine alone, (2) Bacille Calmette Guerin (BCG) vaccine alone, or (3) HepB and BCG vaccines, (4) HepB and BCG vaccines delayed till day 10 at the latest. Each study participant will have a baseline peripheral blood sample drawn at DOL0 and a second blood sample at DOL1,-3, or-7 as well as late timepoints to assess HepB vaccine immunogenicity. Blood will be fractionated via a "small sample big data" standard operating procedure that enables multiple downstream systems biology assays. We will apply both univariate and multivariate frameworks and multi-OMIC data integration to identify features associated with anti-Hepatitis B (anti-HB) titer, an established correlate of protection. Cord blood sample collection from a subset of participants will enable human <i>in vitro</i> modeling to test mechanistic hypotheses identified <i>in silico</i> regarding vaccine action. Maternal anti-HB titer and the infant microbiome will also be correlated with our findings which will be validated in a smaller cohort in Papua New Guinea (<i>N</i> ~ 80). <b>Ethics and Dissemination:</b> The study has been approved by The Gambia Government/MRCG Joint Ethics Committee and The Boston Children's Hospital Institutional Review Board. Ethics review is ongoing with the Papua New Guinea Medical Research Advisory Committee. All de-identified data will be uploaded to public repositories following submission of study output for publication. Feedback meetings will be organized to disseminate output to the study communities. <b>Clinical Trial Registration</b>: Clinicaltrials.gov Registration Number: NCT03246230.

3-Dimensional Integration of Epitaxial Magnetic Tunnel Junctions with New Materials for Future MRAM (2021)

We fabricated novel epitaxial magnetic tunnel junction (MTJ) films with single-crystal spinel MgAl 2 O 4 (001) tunnel barrier on ϕ300 mm Si(001) wafers by sputtering deposition and demonstrated 3-dimensional (3D) integration of the epitaxial MTJ nano-pillars in STT-MRAM by using direct bonding of the epitaxial MTJ wafer and CMOS wafer. The epitaxial MTJs exhibit smaller bit-to-bit variations of magnetic and transport properties compared with poly-crystalline CoFeB/MgO/CoFeB MTJs due to the absence of crystal grains. The 3D integration of epitaxial MTJs allows us to replace conventional MTJ materials (MgO and CoFeB) with new dielectric and ferromagnetic materials, giving great flexibilities and scalability to future MRAM technology. The developed technologies will be applicable also to other kinds of tunnel junction devices such as the Josephson junctions in superconducting qubit for quantum computing.
