Parametric Study on Single Shot and Overlapping Laser Shock Peening on Various Metals via Modeling and Experiments (2010)

Laser shock peening (LSP) under water confinement regime involves several complicated physical phenomena. Among these phenomena, the interaction between laser and coating material during LSP is very important to the laser-induced residual stress, which has an important effect on the fatigue and corrosion properties of the substrate material. To gain a better understanding of this interaction, a series of experiments, including single shot, single-track overlapping, and multitrack overlapping LSP, has been carried out on various metals with different coatings. A 3D finite element model has also been developed to simulate the LSP process. Combining this with a previously developed confined plasma model, which has been verified by the experimental data from literature, the 3D finite element model is used to predict the residual stresses induced in the substrate material as well as the indentation profile on the substrate surface. The model prediction of indentation profiles is compared with the experimental data. The residual stresses in the depth direction are also validated against the X-ray diffraction measurement data for 4140 steel and Ti–6Al–4V, and good agreements are obtained for both predictions. The effect of process parameters on the residual stress is also investigated both experimentally and theoretically.
Complexation of (5H)-Dibenzo[a,d]cyclohepten-5-ylidene to Palladium(II) via the Diazo Route and Evidence of C−H···Pd Interactions (2009)

The reaction of 5-diazo-(5H)-dibenzo[a,d]cycloheptene with a palladium(II) precursor afforded the mononuclear carbocyclic carbene complex in high yield under mild conditions. Characterization of this complex using crystallographic and spectroscopic techniques unexpectedly revealed an almost planar carbocyclic ring system and rare intramolecular preagostic or anagostic C−H···Pd interactions.
On intermittent-contact mode sensing using electrostatically-actuated micro-cantilevers with integrated thermal sensors (2008)

Ultrahigh data storage densities on the order of 1 Tb/in <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> or higher can be achieved by using scanning-probe microscopy techniques to write, read back and erase data on very thin polymer films. The written information is usually read back in contact mode because it is simple to implement and analyze. However, the physical contact between the probe-tip and the media leads to wear of the tip due to abrasive and adhesive forces. Tip wear has adverse effects on the read and write performance at ultrahigh data storage densities. In this paper, an intermittent-contact mode read operation is presented that has been developed to improve the durability of probe-based devices by significantly reducing tip wear. The electrostatic pull-in force between the cantilever and the silicon substrate underneath the polymer medium is used as the actuating force for intermittent-contact operation. The cantilever response is highly nonlinear because of the large adhesion between the tip and the soft polymer medium, which forces the cantilever to remain in contact with the medium for significant fraction of its periodic orbit. For fast and noninvasive reading a feedback controller is designed to ensure reliable small-amplitude operation. Significant improvements in both of the read-lifetime and the rate of signal amplitude-loss were achieved using the intermittent-contact read method compared with the contact read method because of substantial reduction in tip wear rate.
Kernel Bundle Diffeomorphic Image Registration Using Stationary Velocity Fields and Wendland Basis Functions (2015)

In this paper, we propose a multi-scale, multi-kernel shape, compactly supported kernel bundle framework for stationary velocity field-based image registration (Wendland kernel bundle stationary velocity field, wKB-SVF). We exploit the possibility of directly choosing kernels to construct a reproducing kernel Hilbert space (RKHS) instead of imposing it from a differential operator. The proposed framework allows us to minimize computational cost without sacrificing the theoretical foundations of SVF-based diffeomorphic registration. In order to recover deformations occurring at different scales, we use compactly supported Wendland kernels at multiple scales and orders to parameterize the velocity fields, and the framework allows simultaneous optimization over all scales. The performance of wKB-SVF is extensively compared to the 14 non-rigid registration algorithms presented in a recent comparison paper. On both MGH10 and CUMC12 datasets, the accuracy of wKB-SVF is improved when compared to other registration algorithms. In a disease-specific application for intra-subject registration, atrophy scores estimated using the proposed registration scheme separates the diagnostic groups of Alzheimer's and normal controls better than the state-of-the-art segmentation technique. Experimental results show that wKB-SVF is a robust, flexible registration framework that allows theoretically well-founded and computationally efficient multi-scale representation of deformations and is equally well-suited for both inter- and intra-subject image registration.
X-ray stability and response of polymeric photodiodes for imaging applications (2008)

The x-ray stability of photodiodes made of poly(9,9-di-n-octylfluorene-co-benzothiadiazole):perylene diimide, poly[2,7-(9,9-di-n-octylfluorene)-co-(1,4-phenylene-[(4-sec-butylphenyl)imino]-1,4-phenylene)]:perylene diimide and poly(3-hexylthiophene):([6,6]-phenylC61-butyric acid methyl ester) (P3HT:PCBM) blends has been examined up to lifetime doses equivalent to those used in medical x-ray digital imaging applications. Dark currents and external quantum efficiencies (EQEs) are not significantly affected after exposure to 500Gy. Only in the case of P3HT:PCBM is a significant loss in EQE (17% of the initial value) observed. Possible reasons for the observed changes are proposed. When a scintillation layer is attached to the devices, a linear dependence of the photocurrent on the x-ray dose rate is observed for the three material systems.

A heterogeneous ensemble approach for the prediction of the remaining useful life of packaging industry machinery (2018)

We present a method based on heterogeneous ensemble learning for the prediction of the Remaining Useful Life (RUL) of cutting tools (knives) used in the packaging industry. Ensemble diversity is achieved by training multiple prognostic models using different learning algorithms. The combination of the outcomes of the models in the ensemble is based on a weighted averaging strategy, which assigns weights proportional to the individual model performances on patterns of a validation set. The proposed heterogeneous ensemble has been applied to real condition monitoring knife data. It has provided more accurate RUL predictions compared to those of each individual base model.
Effect of Cyclic Corrosion and Joining Method on the Strength of Multimaterial Double Lap Joints (2021)

Abstract The effect of cyclic corrosion on the static performance of multi-material double lap joints is investigated. Carbon-Fiber-Reinforced thermoplastic composite substrates are joined to Aluminum substrates using bonding-only, bolting-only, or by hybrid bonding-and-bolting methods. Polyurethane-based or epoxy-based structural adhesives are used. Surface roughness is maintained constant and evaluated with an optical profilometer. The quasi-static performance of baseline joints is assessed, and the results from the various joining methods are compared. Cyclic corrosion testing of Double Lap joints is performed in accordance with a GMW14872 3-stage laboratory standards for 30 one-full-day cycles. Quasi-static lap shear tests of test samples are performed at various stages of corrosion cycling, and progressive strength degradation is observed for bonded-only and hybrid bonded-and-bolted joints. Bolted-only joints do not show significant performance loss. Results, discussion, and conclusions are provided.

BLACK AND GRAY (2005)

Abstract This chapter examines a crucial but often neglected part of the story, one that powerfully influenced the way in which the debate in the Confederacy unfolded. It compares the white Southern leadership's expectations and claims about wartime slave conduct with what slaves actually did between 1861 and 1865. In the process, it shows how the beliefs and actions of black southerners became a major military factor, not only helping to reshape Union policy but also limiting the options and influencing the choices of the Confederacy's leaders.
Polymer structure effect on dissolution characteristics and acid diffusion in chemically amplified deep ultraviolet resists (1997)

The role of molecular weight dispersion (Mw/Mn) of base phenolic resin was investigated in chemically amplified positive KrF resists. The resists consisted of tert-butoxycarbonyl (t-BOC) blocked polystyrene as base resin and 2,4-dimethylbenzenesulfonic acid derivative as photoacid generator, and the Mw/Mn value was changed as 1.2, 4.0, and 9.0. Not only dissolution rate contrast, but also the slope m of log(dissolution rate)-log(exposure dose) plots increased with decreasing Mw/Mn. In the case of low Mw/Mn, the molecular structure becomes more homogeneous, so resist film could be dissolved uniformly via constant developer penetration into film. This uniform dissolution characteristics may be attributable to the origin of dispersion effects mentioned above. Furthermore, higher acid diffusion property and smooth pattern side wall were obtained without side wall roughness in lower Mw/Mn. This fact indicates that acid diffusion length is also uniform within resist film in the case of low Mw/Mn. Based on the experimental analysis, the clear relationship among Mw/Mn, dissolution characteristics and acid diffusion behavior in resist film was obtained. Moreover, it was found that lower Mw/Mn has advantage for improving inherent resist performance.

An electrospray system comprises a liquid extraction surface sampling probe. The probe comprises a probe body having a liquid inlet and a liquid outlet, and having a liquid extraction tip. A solvent delivery conduit is provided for receiving solvent liquid from the liquid inlet and delivering the solvent liquid to the liquid extraction tip. An open liquid extraction channel extends across an exterior surface of the probe body from the liquid extraction tip to the liquid outlet. An electrospray emitter tip is in liquid communication with the liquid outlet of the liquid extraction surface sampling probe. A system for analyzing samples, a liquid junction surface sampling system, and a method of analyzing samples are also disclosed.
Heterogenised Molecular Catalysts for Sustainable Electrochemical CO2 Reduction (2022)

Abstract There has been a rapid rise in interest regarding the advantages of support materials to protect and immobilise molecular catalysts for the carbon dioxide reduction reaction (CO 2 RR) in order to overcome the weaknesses of many well‐known catalysts in terms of their stability and selectivity. In this Review, the state of the art of different catalyst‐support systems for the CO 2 RR is discussed with the intention of leading towards standard benchmarking for comparison of such systems across the most relevant supports and immobilisation strategies, taking into account these multiple pertinent metrics, and also enabling clearer consideration of the necessary steps for further progress. The most promising support systems are described, along with a final note on the need for developing more advanced experimental and computational techniques to aid the rational design principles that are prerequisite to prospective industrial upscaling.
Photo-aligning and Photo-patterning by Photosensitive Azo-dye Layers (2008)

New photosensitive materials for photo- aligning (PA) and photo-patterning of polarizers and phase retarders and to produce efficient new liquid crystal display (LCD) prototypes based on this technology were investigated. The photoaligning technology enables us to obtain transflective displays, by putting a special configuration of patterned LC alignment or patterned poiymerizabie LC (LCP) phase retarders for transmissive and reflective part of each pixel.
Isolation of a hydroxytyrosol lactone conjugate from olive mill waste water with antioxidant activity (2014)

Olive mill waste water (OMWW) is the major byproduct of olive oil industry with destructive impact to the environment, ranging from aesthetic devalorization of countryside to severe genetic toxicity to eukaryotic organisms. Nevertheless, OMWW is a valuable source of high added value products such as hydroxytyrosol (1) and lactones deriving from the secoiridoid core of olive constituents (2) [1]. Under the context of revealing the elusive non-phenolic substances present in OMWW, we proceeded with the investigation and qualitative characterization of an enriched extract of OMWW, which resulted in the isolation and structural characterization of seven secoiridoid lactones, through fast centrifugal partition chromatography (FCPC) separation. Structural elucidation of the isolated compounds was performed with the aid of 1D and 2D NMR and mass spectroscopy. Among the isolates, lactone 3 is a new derivative characterized by the ester linkage of hydroxytyrosol with lactone 2. Although the lactone content of OMWW has been investigated in the past, it is the first time that a lactone derivative bearing a hydroxytyrosol moiety is found. Additionally, the antioxidant capacity of compounds 1, 2 and 3 was studied at a cellular level using human skin fibroblasts in the well known DCFH-DA assay where 3 showed an activity similar to equimolar concentrations of Trolox.
Discovery of Antiglioma Activity of Biaryl 1,2,3,4-Tetrahydroisoquinoline Derivatives and Conformationally Flexible Analogues (2006)

Cultured rat astrocytes and C6 rat glioma were used as a differential screen for a variety of 1,2,3,4-tetrahydroisoquinoline (THI) derivatives. Compound 1 [1-(biphenyl-4-ylmethyl)-1,2,3,4-tetrahydroisoquinoline-6,7-diol hydrochloride] selectively blocked the growth of C6 glioma leaving normal astrocytes relatively unaffected. The potential for clinical utility of 1 was further substantiated in human gliomas and other tumor cell lines. Preliminary SAR of this activity was characterized by synthesis and testing of several THI and conformationally flexible variants.

Blue Communications for Edge Computing: the Reconfigurable Intelligent Surfaces Opportunity (2022)

Wireless traffic is exploding, due to the myriad of new connections and the exchange of capillary data at the edge of the networks to operate real-time processing and decision making. The latter especially affects the uplink traffic, which will grow in 6G and beyond networks, calling for new optimization metrics that include energy, service delay, and electromagnetic field (EMF) exposure (EMFE). To this end, reconfigurable intelligent surfaces (RISs) represent a promising solution to mitigate the EMFE, thanks to their ability of shaping and manipulating the impinging electromagnetic waves. In line with this vision, this paper proposes an online adaptive method to mitigate the EMFE under end-to-end delay constraints of a computation offloading service, in the context of RIS and multi-access edge computing (ME C)-aided wireless networks. The goal is to minimize the long-term average of the EMF human exposure under such constraints, investigating the advantages of RISs towards blue (i.e. low EMFE) communications. A multiple-input multiple-output (MIMO) system is investigated as part of the visions towards 6G. Focusing on a typical scenario of computation offloading, the method jointly and adaptively optimizes user precoding, transmit power, RIS reflectivity parameters, and receiver combiner, with theoretical guarantees on the desired long-term performance. Besides the theoretical results, numerical simulations assess the performance of the proposed algorithm, when exploiting accurate antenna patterns, thus showing the advantage of the RIS and that of our method, compared to benchmark solutions.

Assays for Studying the Role of Vitronectin in Bacterial Adhesion and Serum Resistance (2018)

Bacteria utilize complement regulators as a means of evading the host immune response. Here, we describe protocols for evaluating the role vitronectin acquisition at the bacterial cell surface plays in resistance to the host immune system. Flow cytometry experiments identified human plasma vitronectin as a ligand for the bacterial receptor outer membrane protein H of Haemophilus influenzae type f. An enzyme-linked immunosorbent assay was employed to characterize the protein-protein interactions between purified recombinant protein H and vitronectin, and binding affinity was assessed using bio-layer interferometry. The biological importance of the binding of vitronectin to protein H at the bacterial cell surface in evasion of the host immune response was confirmed using a serum resistance assay with normal and vitronectin-depleted human serum. The importance of vitronectin in bacterial adherence was analyzed using glass slides with and without vitronectin coating, followed by Gram staining. Finally, bacterial adhesion to human alveolar epithelial cell monolayers was investigated. The protocols described here can be easily adapted to the study of any bacterial species of interest.

Production of core‐shell polymer particles‐containing cardanol by semibatch combined suspension/emulsion polymerization (2013)

The main objective of the present work is to study the copolymerization of cardanol and styrene for production of polymer beads intended for enzyme immobilization. Initially, free‐radical copolymerizations of cardanol and styrene were performed in suspension, showing that effective incorporation of cardanol into polystyrene chains is not possible at usual suspension polymerization conditions. Then, free‐radical copolymerizations of cardanol and styrene were performed in semibatch combined suspension/emulsion reactions, showing that cardanol can be incorporated into polystyrene chains (as confirmed through Nuclear Magnetic Resonance and Differential Scanning Calorimetry analyses) when it is fed as an emulsion constituent. In these cases, the final polymer particles presented the usual core/shell morphology, with high‐specific areas and large average pore diameters, as required by enzyme immobilization applications.

Engineered Polyelectrolyte Multilayer Substrates for Adhesion, Proliferation, and Differentiation of Human Mesenchymal Stem Cells (2009)

Polyelectrolyte multilayer coatings have emerged as substrates to control cellular behavior, but interactions with human multipotent mesenchymal stromal cells (MSCs) have not been studied. We looked at layer-by-layer coatings of cationic poly-L-lysine (PLL) and anionic hyaluronic acid (HA) as substrates for MSCs of placenta and adipose tissue. This system allows for modulation of thickness (number of deposition cycles), stiffness (chemical cross-linking of bulk layer), and adhesiveness (fibronectin (FN) interface). Native, as-built PLL/HA multilayer coatings were poorly adhesive for MSCs despite spectroscopy-confirmed high surface density of pre-adsorbed FN. Stratification of cross-linked PLL/HA multilayers of different stiffnesses revealed that multilayers modified with a high cross-linking regimen became efficient substrates for MSC adhesion and proliferation. MSCs on cross-linked multilayers grew to confluence. Using comparative confocal microscopy analysis of PLL/HA multilayers with physically adsorbed versus chemically coupled FN, we demonstrated that cross-linking strongly influenced FN surface distribution, leading to denser presentation of adhesion sites for cells. The covalent affixation of FN promoted focal adhesion formation and was critical to maintaining densely grown MSC cultures over weeks for their differentiation. Multilayer-bound MSCs were capable of differentiating into osteocytes and chondrocytes upon culture with induction factors. Together, cross-linked, FN-terminated PLL/HA multilayers provide a versatile platform for studies of human MSCs for biotechnological or therapeutic applications.
High level analysis of trade-offs across different partitioning schemes for wireless applications (2011)

With the advent of heterogeneous MPSoC (Multi-Processors System-on-Chip) implementations of wireless applications, system partitioning and mapping has become a key challenge. To achieve efficient designs, system partitioning should simultaneously consider application characteristics, architecture constraints and physical design costs. It is also important to analyze the impact of partitioning on the system's area, energy and performance, as early as possible in the design flow. In this paper, we analyze the impact of different partitioning schemes for lattice reduction based MIMO detector. We show the trade-offs due to different partitioning schemes on area, energy and data parallelization factor for a given performance target for different number of processors. We carry out analysis based on high level estimates derived from the application and a set of characterized datapath and memory primitives for a template based architecture.
