EM analysis of smart shelf RFID antenna with reconfigurable interrogation zone (2016)

This paper presents the design and EM analysis of a near-field RFID antenna for the smart shelf applications where spatially-reconfigurable interrogation zone is required. Antenna operation is based on the EM coupling between the open-ended or shorted microstrip (MS) feed line and parallel planar metal strips printed on top of a dielectric layer. The novelty of the proposed design corresponds to utilizing the RF switches altering the length of meander MS line and thus changing the phase distribution of the radiating antenna elements. Near-field distributions calculated in the planes parallel and normal to the antenna surface illustrate the mechanism of extending an area of strong E-field necessary to activate multiple RFID tags.
Modelling and data analysis of GPS reflections from low earth orbit (2006)

GPS-Reflectometry studies the forward scattering of GPS reflections for the purposes of determining surface characteristics. This can be used for measuring sea states, soil humidity and polar ice age. Theoretical and experimental studies have been mainly carried out on ground and airborne platforms. A space-borne platform, however, would provide broader spatial and temporal coverage for Earth Observation and disaster monitoring. Currently UK-DMC represents the only Low Earth Orbit (LEO) satellite able to routinely schedule GPS reflection observations from ocean surfaces. Earlier research work has shown that Delay-Doppler Maps (DDMs) derived from reflections from space, although weak, will vary with geometry and sea state. In this work we extend these results by developing a modelling technique that derives relationships between wind conditions, sea roughness and GPS reflections received from a LEO satellite. We present simulation results and two-dimensional fitting of experimental data to compare DDMs. A novel technique is also proposed for reversing experimental DDMs obtained from GPS-R back to spatial energy maps. Preliminary data inversion results have been included to demonstrate the feasibility of this new methodology.
Linear microwave downconverting RF-to-bits link (2008)

We present a RF digital receiver offering fiber optic transport of microwave signals and the linear conversion of the information band to the digital domain with high resolution. The architecture utilizes linear wideband electro-optic phase encoding, quadrature detection/downconversion and digital signal processing to achieve unprecedented linearity. Applications, results, technology comparisons and directions for future work will be discussed.
Circumstellar carbon chain molecules: A density function theory study of C<i>n</i>O, <i>n</i>=3–9 (1995)

The infrared vibrational frequencies and intensities of the CnO linear chains, n=3–9, in their electronic ground state is predicted at the Becke–Lee–Yang–Parr (BLYP) level of theory. The computational model is assessed in three steps: (i) comparison of calculated and experimental rotational parameters for the whole series; (ii) comparison of experimental and calculated infrared frequencies, intensities and isotopic shifts for C3O (this molecule can be considered the prototype of the chains whose ground electronic state is 1Σ+); (iii) comparison of calculated and experimental infrared frequencies and intensities for C4O (this molecule can be considered the prototype of the chains whose ground electronic state is 3Σ−). The excellent agreement between experimental and computational results allows the prediction of the infrared pattern to 20 cm−1 for the frequencies and a few percent for the relative intensities. Analysis of the infrared intensities in terms of local atomic oscillators within the chains shows that while for short chains the intensity arises from the motion of the two carbon atoms nearest to the oxygen, for C7O and C9O the intensity arises in conjunction with the motion of carbon atoms close to, but not at, the other end of the molecule. For these two molecules, the infrared intensity is therefore similar in nature to that of pure carbon chains.
2007 IXA Presidential Address. Progress toward an ideal source animal: opportunities and challenges in a changing world (2008)

Xenotransplantation holds great promise for the treatment of end-stage organ failure and tissue injury. Recent advances in our understanding of the immunological hurdles to xenotransplantation and the development of genetic modification approaches to overcome them increase the likelihood of success. Exciting advances in these areas were presented at the Joint Congress of the IXA, the Cell Transplant Society and the International Pancreas and Islet Transplant Association in Minneapolis in September, 2007. However, in order to minimize infectious risks and encourage positive public perception of xenotransplantation, clinical trials should be initiated with appropriate monitoring and oversight procedures in place and only when there is high expectation of clinical benefit.

Template Dissolution Interfacial Patterning of Single Colloids for Nanoelectrochemistry and Nanosensing (2020)

Deterministic positioning and assembly of colloidal nanoparticles (NPs) onto substrates is a core requirement and a promising alternative to top-down lithography to create functional nanostructures and nanodevices with intriguing optical, electrical, and catalytic features. Capillary-assisted particle assembly (CAPA) has emerged as an attractive technique to this end, as it allows controlled and selective assembly of a wide variety of NPs onto predefined topographical templates using capillary forces. One critical issue with CAPA, however, lies in its final printing step, where high printing yields are possible only with the use of an adhesive polymer film. To address this problem, we have developed a template dissolution interfacial patterning (TDIP) technique to assemble and print single colloidal AuNP arrays onto various dielectric and conductive substrates in the absence of any adhesion layer, with printing yields higher than 98%. The TDIP approach grants direct access to the interface between the AuNP and the target surface, enabling the use of colloidal AuNPs as building blocks for practical applications. The versatile applicability of TDIP is demonstrated by the creation of direct electrical junctions for electro- and photoelectrochemistry and nanoparticle-on-mirror geometries for single-particle molecular sensing.
Fibronectin-binding protein of Streptococcus equi subsp. zooepidemicus (1996)

By screening a genomic lambda library of Streptococcus equi subsp. zooepidemicus, we have cloned and sequenced a gene, termed fnz, encoding a fibronectin (Fn)-binding protein called FNZ. On the basis of the deduced amino acid sequence of FNZ, the mature protein has a molecular mass of approximately 61 kDa. Analysis of FNZ reveals a structural organization similar to that of other cell surface proteins from streptococci and staphylococci. The Fn-binding activity is localized to two domains in the C-terminal part of FNZ. One domain is composed of five repeats, which contain a motif similar to what has earlier been found in other Fn-binding proteins in streptococci and staphylococci. The first and second repeats are separated by a short stretch of amino acids, including the motif LAGESGET, which is an important part of the second Fn-binding domain. This motif is also present in an Fn-binding domain (UR) in protein F of Streptococcus pyogenes. A fusion protein covering the Fn-binding domain of FNZ inhibits the binding of the 29-kDa N-terminal fragment of Fn to cells of various streptococcal species as well as to Staphylococcus aureus.
Drinking Water From Private Wells and Risks to Children (2023)

Drinking water for approximately 23 million US households is obtained from private wells. These wells can become contaminated by pollutant chemicals or pathogenic organisms, leading to significant illness. Although the US Environmental Protection Agency and all states offer guidance for construction, maintenance, and testing of private wells, most states only regulate the construction of new private water wells. With a few exceptions, there is little regulation after construction. Well owners are responsible for their own wells. Children may also drink well water at child care or when traveling. Illness resulting from children's ingestion of contaminated water can be severe. This report reviews relevant aspects of groundwater and wells; describes the common chemical and microbiologic contaminants; gives an algorithm with recommendations for inspection, testing, and remediation for wells providing drinking water for children; and provides references and Internet resources for more information.
Preliminary Investigation of the Mechanisms Underlying the Effects of Manipulation (2011)

The underlying mechanisms explaining the benefits of SMT appear to be multifactorial. Both spinal stiffness characteristics and LM recruitment changes appear to play a role.
EARLY CROSSOVER OF INDUCTION CHEMOTHERAPY IN SMALL CELL LUNG CARCINOMA (1983)

Abstract: The aim of this trial was to assess whether early crossover induction chemotherapy would improve the complete response rate in patients with small cell lung carcinoma. Tumour markers were defined in all 48 patients at diagnosis. The patients were reassessed after three and six cycles of chemotherapy and classified as having either complete, partial or non response of tumour on each occasion. Initial induction therapy consisted of cyclophosphamide, vincristine and adriamycin (T1). The therapy of the patients with no tumour response was changed to a regimen (T2) consisting of VP16‐213, procarbazine, CCNU and high dose methotrexate with folinic acid rescue. The patients with partial tumour response were randomised to receive either T1 or T2, while patients with complete tumour response continued with T1. In those patients classified initially as having partial tumour response, crossover chemotherapy did not improve tumour response or survival. Similarly, in patients with no tumour response there was not an acceptable improvement. We conclude that non cross resistant crossover chemotherapy using these drug regimens confers no added benefit when compared with continuing the initial therapy.
Structure and impact properties of a thermoplastic elastomer/silly putty blend (2021)

Abstract The structure and impact properties of a thermoplastic elastomer/silly putty blend are explored. The impact‐resistant materials are made with polyolefin‐based thermoplastic elastomer HYBRAR™ 5127 and silly putty DOWSIL™ 3179. The peak impact force decreases with the content of silly putty, as part of the impact energy might be dissipated by the dissociation of boron–oxygen dynamic dative bonds in silly putty. It is also observed that the crack behavior of samples under impact is related to the phase structure of silly putty in the samples. For the samples with high content of silly putty, a macroscopic crack is observed for these samples under impact, as a crack can spread in the continuous phase structure of silly putty. Different energy dissipation ratios in rheological, compression and impact experiments are also observed. It is concluded that the results of linear dynamic oscillatory shear and compression at a low strain rate cannot give a direct predication of energy dissipation ratios of samples under impact at a high strain rate. © 2021 Society of Industrial Chemistry.
<i>In vitro</i> patterning of pluripotent stem cell-derived intestine recapitulates <i>in vivo</i> human development (2016)

The intestine plays a central role in digestion, nutrient absorption and metabolism, with individual regions of the intestine having distinct functional roles. Many examples of region-specific gene expression in the adult intestine are known, but how intestinal regional identity is established during development is a largely unresolved issue. Here, we have identified several genes that are expressed in a region-specific manner in the developing human intestine. Using human embryonic stem cell-derived intestinal organoids, we demonstrate that the duration of exposure to active FGF and WNT signaling controls regional identity. Short-term exposure to FGF4 and CHIR99021 (a GSK3β inhibitor that stabilizes β-catenin) resulted in organoids with gene expression patterns similar to developing human duodenum, whereas longer exposure resulted in organoids similar to ileum. When region-specific organoids were transplanted into immunocompromised mice, duodenum-like organoids and ileum-like organoids retained their regional identity, demonstrating that regional identity of organoids is stable after initial patterning occurs. This work provides insights into the mechanisms that control regional specification of the developing human intestine and provides new tools for basic and translational research.
Analysis of Conversion on Direct Copper Plating Using Pd/Sn Mixed Catalyst. (1999)

The mechanism of direct copper plating on nonconductive resin substrates was studied using high-resolution TEM, SEM and XPS. Substrates were catalyzed by Pd/Sn catalyst and subsequently immersed in alkaline solution containing either copper ions or sulfide ions before electroplating. After conversion in the alkaline solution containing copper ions, catalyst colloid particles formed clusters and crystallinity improved. Sulfide compounds, however, formed by conversion in alkaline solution containing sulfide ions. Both conversion techniques markedly promoted propagation in electroplating. The effect is explained by propagation in which improved palladium colloid crystallinity and palladium sulfide formed in conversion play a critical role in determining the propagation rate.

Epithelioids: Self-sustaining 3D epithelial cultures to study long-term processes (2023)

ABSTRACT Studying long-term biological processes such as the colonization of aging epithelia by somatic mutant clones has been slowed by the lack of suitable culture systems. Here we describe epithelioids, a facile, cost-effective method of culturing multiple mouse and human epithelia. Esophageal epithelioids self-maintain without passaging for at least a year, recapitulating the 3D structure, cell dynamics, transcriptome, and genomic stability of the esophagus. Live imaging over 5 months showed epithelioids replicate in vivo cell dynamics. Epithelioids enable the study of cell competition and mutant selection in 3D epithelia, and how anti-cancer treatments modulate the competition between transformed and wild type cells. Epithelioids are a novel method with a wide range of applications in epithelial tissues, particularly the study of long term processes, that cannot be accessed using other culture models.
STM and ECSTM Study of the Formation and Structure of Self-Assembling Osmium Complexes on Pt(111) (1996)

The formation and structure of the self-assembling transition metal complex [Os(bpy)2(dipy)Cl](PF6) (bpy is 2,2‘-bipyridine, dipy is trimethylene-4,4‘-bipyridine) adsorbed onto a Pt(111) substrate was studied using scanning tunneling microscopy (STM) and electrochemical scanning tunneling microscopy (ECSTM). The growth of a spread submonolayer was observed in real time while simultaneously measuring the adsorbate coverage using cyclic voltammetry. Molecularly resolved images of the monolayer crystallized onto the Pt(111) surface, taken in air and showing a rectangular close-packed structure, were compared with images of the monolayer obtained in-situ in electrolyte solution and under potential control.

Modeling Computational Security in Long-Lived Systems, Version 2 (2008)

Abstract. For many cryptographic protocols, security relies on the assumption that adversarial entities have lim-ited computational power. This type of security degrades progressively over the lifetime of a protocol. However, some cryptographic services, such as timestamping services or digital archives, are long-lived in nature; they are expected to be secure and operational for a very long time (i.e., super-polynomial). In such cases, security cannot be guaranteed in the traditional sense: a computationally secure protocol may become insecure if the attacker has a super-polynomial number of interactions with the protocol. This paper proposes a new paradigm for the analysis of long-lived security protocols. We allow entities to be active for a potentially unbounded amount of real time, provided they perform only a polynomial amount of work per unit of real time. Moreover, the space used by these entities is allocated dynamically and must be polynomially bounded. We propose a new notion of long-term implementation, which is an adaptation of computational indistinguishability to the long-lived setting. We show that long-term implementation is preserved under polynomial parallel composi-tion and exponential sequential composition. We illustrate the use of this new paradigm by analyzing some security properties of the long-lived timestamping protocol of Haber and Kamat. 1
Nanotecnologia en el hormigón y hormigones autocompactantes (2009)

Dentro de las jornadas tecnicas de la Catedra de Innovacion en Tecnologia del
Hormigon patrocinada por BASF, MOLINS y BEKAERT (Catedra BMB-UPC), en la presente ocasion se ha querido plantear dos temas de gran vigencia como son: la nanotecnologia en el mundo del hormigon y la vision estructural de los hormigones autocompactantes.
Respecto a la nanotecnologia cabe senalar que si bien tiene un desarrollo reciente ya
esta bien introducida en distintos sectores de la ciencia, tecnologia y ingenieria. La
nanotecnologia puede mejorar nuestro entendimiento de los origines de las
caracteristicas basicas de materiales muy comunes, de estructuras y de procesos de
fabricacion. Permite de tener una caracterizacion adelantada, hasta una prediccion y control, de las caracteristicas de los materiales. Su potencial de desarrollo es tal que se lo considera ya como la revolucion industrial del siglo 21.
En cuanto a los hormigones autocompactantes, hay que senalar que si bien llevan
tiempo en el mercado, existen barreras importantes en su aplicacion in situ, donde
alcanzan cotas inferiores al 2%, en contraposicion del 50 al 60 % en los prefabricados.
Entre estas barreras, puede situarse la falta de documentos normativos, hasta la reciente aparicion del anejo de la EHE08, o bien la falta de un planteamiento estructural de este hormigon. Este es el punto de vista que se quiere hacer enfasis en el desarrollo de la jornada desde diferentes puntos de vista, tanto desde el proyecto, como la construccion como el material.
Para dar respuesta a ambos retos se ha contado como en otras ocasiones, con grandes
especialistas tanto el ambito internacional, como del ambito nacional, manteniendo un
equilibrio entre los provenientes del mundo academico como del campo profesional.
Estos especialistas son, por orden alfabetico, Carmen Andrade, Pere Borralleras, Hugo Corres, Paulo Monteiro, Jose Ma Navarro y Surendra Shah.
Assessing the business value of RFID under uncertain conditions (2008)

Radio Frequency Identification (RFID) and other wireless technologies are currently transitioning from proto-type application towards real productive systems. Possible investments into these new technologies must meet economic criteria and generate a certain business value. Anyhow, estimating all cost factors and saving opportun-ities is difficult due to uncertainty in input data. This paper presents a review of current approaches to determine the business value of RFID systems. Moreover, it points out the most important factors that influence the busi-ness value and proposes additional concepts to handle uncertainty in the calculation of the business value of an RFID system.
Solvent Polarity Governs Ultrafast Structural Dynamics: A Case Study of 4-Dimethylamino-4′-carbomethoxydiphenylacetylene (2023)

The compound 4-dimethylamino-4′-carbomethoxydiphenylacetylene (DACM-DPA) is a donor-π-acceptor system that exhibits significant charge transfer character in the excited state in polar solvents. Femtosecond transient absorption measurements in n-hexane, acetonitrile, and methanol exhibit excited-state lifetimes of >2 ns, ∼500 ps, and ∼30 ps, respectively. Femtosecond Raman measurements of DACM-DPA elucidated the intricate structural dynamics during the excited-state evolution by revealing distinct vibrational signatures of DACM-DPA in these solvents. In the case of n-hexane solvent, vibrational bands at 2075 cm–1 (C≡C) and 1600 cm–1 (C═C) stretch exist throughout the excited-state lifetime. However, in the case of polar solvents, the amplitudes of vibrational frequencies at 2098 cm–1 (C≡C), 1618 cm–1 (C═C, acetonitrile), and 1603 cm–1 (C═C, methanol) diminish in a time period of 2.5 ps (acetonitrile) and 6.5 ps (methanol) along with the appearance of new bands at 2082 cm–1 (cumulene stretch) and 1582 cm–1 (quinoid stretch), clearly revealing the formation of an intramolecular charge-separated state. Furthermore, these experimental observations are corroborated by computations using DFT and TD-DFT.
