Optical multiple-image authentication scheme based on the phase retrieval algorithm in gyrator domain (2017)

A novel optical multiple-image authentication scheme based on the phase retrieval algorithm is presented in gyrator domain. According to a plain image, only one phase-only mask is obtained as the encrypted result by using the proposed phase retrieval algorithm, which has a fast convergence rate and good performance on mean square error. Afterwards, the sparsely encrypted distribution is extracted from the phase-only mask by selecting a certain percentage of pixels randomly. Different from other multiple-image authentication system based on space multiplexing, all sparsely encrypted distributions of plain images are finally integrated into the ciphertext by making use of the inter-modulation operation of phase masks, where the decryption process can be performed efficiently without any cross-talk noise and the encrypted capacity is nearly unlimited. Only when the secret keys are correct, the content of the plain images can be authenticated, in which the authentication process can be implemented optically by using the architecture of double random phase encoding. Simulation results are given to demonstrate the feasibility and robustness of the proposed scheme.

Retroviral and Lentiviral Safety Analysis of Gene-Modified T Cell Products and Infused HIV and Oncology Patients (2017)

Replication-competent retrovirus/lentivirus (RCR/L) and insertional oncogenesis are potential safety risks with integrating viruses in gene-modified cell therapies. As such, the Food and Drug Administration guidances outline RCR/L-monitoring methods throughout the entire gene therapy treatment cycle. We present data for 17 vector lots, 375 manufactured T cell products, and 308 patients post-infusion across both HIV and oncology indications, showing no evidence of RCR/L. Given our data, a Poisson probability model estimates that a single patient, or a group of patients, would need to be followed for at least 52.8 years to observe one positive RCR/L event, highlighting the unlikelihood of RCR/L development. Additionally, we estimate the median time for lentivirus-modified T cell products to fall below the 1% vector sequence threshold in peripheral or whole blood that would trigger vector integration site analysis. These estimated times are 1.4 months in hematologic malignancies, 0.66 month in solid tumors, and 0.92 month in HIV. Based on these considerable safety data in HIV and oncology and recent Biologics License Applications filed for lentiviral-modified T cell products for hematologic malignancies, this may be an opportune time to re-evaluate the current guidelines for T cell gene therapy product testing and long-term patient monitoring.

ESD verification has become increasingly complex as integrated circuits move towards system-on-chip (SOC) applications. The result of this is that newer ESD specific checking techniques are required. This paper describes the ESD checking flow of these tools, the testing of them, and the real design errors they have uncovered.
Optoacoustic and photothermal material inspection techniques (1982)

Infrared photothermal material inspection in a transmission arrangement is compared to optoacoustic imaging with respect to depth range, resolution, and interpretation of results. The photothermal method seems to be advantageous, but depth information is not obtained.
Power line communications: an implementation of a real timecontrol architecture for smart grid (2012)

Negli ultimi anni e aumentata la presenza di risorse energetiche
distribuite (DERs) nella rete elettrica. La visione della ``rete
intelligente'' (Smart Grid) cerca di introdurre un'infrastruttura di
controllo e di comunicazione di tipo distribuito in modo da sfruttare le potenzialita delle DERs e quindi potenziare e modernizzare la rete di distribuzione attuale. Applicandolo alle reti a bassa tensione, la cosiddetta ``Smart Microgrids'', si e sviluppato un banco di prova (testbed) che permette di dimostrare tecniche di riduzione delle perdite di distribuzione. La soluzione adottata bilancia localmente la potenza reattiva della microgrid attraverso il controllo delle risorse locali ottenendo una riduzione della corrente necessaria per alimentare la rete. Inoltre, vengono analizzati i vantaggi nell'usare la linea elettrica come mezzo di comunicazione e vengono evidenziati alcuni standard di comunicazione

Removal of TDS from Cooling Tower Water by Using EDTA-Modified Bagasse Fibers (2009)

Modified by ethylenediaminetetraacetic acid (EDTA) salts and unmodified bagasse fibers were tested for the removal of total dissolved solids (TDSs) from cooling tower water. Parameters such as hydrogen ion concentration (pH), particle size of bagasse fibers, and the concentrations of adsorbent and adsorbate were studied to optimize the conditions to be applied on a commercial scale for the decontamination of effluents of cooling tower water. The optimum pH for TDS removal was between 6 and 6.5. The efficiency of TDS removal increased when the size of fiber particles decreased (100 μm) and when the concentration of EDTA salt increased to reach 78 mg/g of modified bagasse fibers. The adsorption parameters were determined using both Langmuir and Freundlich isotherms. The preferential mechanisms for the retention of TDSs are a complexation process between the TDSs and chemical functions present on the surface of fibers, and the chelation process with the EDTA attached to the fibers. The results obtained could be valuable for application to cooling tower water treatment and for the softening of hard drinking water.
Acellular Pertussis Vaccine Protects against Exacerbation of Allergic Asthma Due toBordetella pertussisin a Murine Model (2005)

The prevalence of asthma and allergic disease has increased in many countries, and there has been speculation that immunization promotes allergic sensitization. Bordetella pertussis infection exacerbates allergic asthmatic responses. We investigated whether acellular pertussis vaccine (Pa) enhanced or prevented B. pertussis-induced exacerbation of allergic asthma. Groups of mice were immunized with Pa, infected with B. pertussis, and/or sensitized to ovalbumin. Immunological, pathological, and physiological changes were measured to assess the impact of immunization on immune deviation and airway function. We demonstrate that immunization did not enhance ovalbumin-specific serum immunoglobulin E production. Histopathological examination revealed that immunization reduced the severity of airway pathology associated with sensitization in the context of infection and decreased bronchial hyperreactivity upon methacholine exposure of infected and sensitized mice. These data demonstrate unequivocally the benefit of Pa immunization to health and justify selection of Pa in mass vaccination protocols. In the absence of infection, the Pa used in this study enhanced the interleukin-10 (IL-10) and IL-13 responses and influenced airway hyperresponsiveness to sensitizing antigen; however, these data do not suggest that Pa contributes to childhood asthma overall. On the contrary, wild-type virulent B. pertussis is still circulating in most countries, and our data suggest that the major influence of Pa is to protect against the powerful exacerbation of asthma-like pathology induced by B. pertussis.
Time domain modeling of active materials (2018)

This talk will overview the recent advances and details of time domain modeling of active materials. We focus on the multiphysics modeling of multi-level atomic systems coupled to full-wave time domain Maxwell's solver to include the transitions taking place in gain media. Different atomic systems, 2-level and higher, are reviewed and compared. The details of efficient and universal numerical implementation, as well as experimental characterization and calibration of the model are discussed. Also, we address simulation techniques that handle spontaneous emission and stochastic noise.

On the Dynamics of Spatial Updating (2022)

Most of our knowledge on the human neural bases of spatial updating comes from functional magnetic resonance imaging (fMRI) studies in which recumbent participants moved in virtual environments. As a result, little is known about the dynamic of spatial updating during real body motion. Here, we exploited the high temporal resolution of electroencephalography (EEG) to investigate the dynamics of cortical activation in a spatial updating task where participants had to remember their initial orientation while they were passively rotated about their vertical axis in the dark. After the rotations, the participants pointed toward their initial orientation. We contrasted the EEG signals with those recorded in a control condition in which participants had no cognitive task to perform during body rotations. We found that the amplitude of the P<sub>1</sub>N<sub>1</sub> complex of the rotation-evoked potential (RotEPs) (recorded over the vertex) was significantly greater in the Updating task. The analyses of the cortical current in the source space revealed that the main significant task-related cortical activities started during the N<sub>1</sub>P<sub>2</sub> interval (136-303 ms after rotation onset). They were essentially localized in the temporal and frontal (supplementary motor complex, dorsolateral prefrontal cortex, anterior prefrontal cortex) regions. During this time-window, the right superior posterior parietal cortex (PPC) also showed significant task-related activities. The increased activation of the PPC became bilateral over the P<sub>2</sub>N<sub>2</sub> component (303-470 ms after rotation onset). In this late interval, the cuneus and precuneus started to show significant task-related activities. Together, the present results are consistent with the general scheme that the first task-related cortical activities during spatial updating are related to the encoding of spatial goals and to the storing of spatial information in working memory. These activities would precede those involved in higher order processes also relevant for updating body orientation during rotations linked to the egocentric and visual representations of the environment.
A mass-loading effect LiNbO/sub 3/ SAW sensor (2005)

A mass-loading effect SAW sensor with a quadrate (3mm/spl times/3mm) mass-loading effect groove is presented. Its input and output IDTs have 40 pairs and 60 pairs of aluminum electrodes respectively. A photoresist layer is covered on the surface of LiNbO/sub 3/ substrate to protect the aluminum electrodes and to construct the quadrate groove in the center of the sonic path. The tiny loading mass in this groove leads into a tiny center frequency shift of the SAW sensor. The loading mass density can be obtained from the frequency shift and the sensitivity curve. This kind of SAW mass-loading effect sensor can be used in direct measurement and dual SAW sonic path comparative measurement. The input and output IDTs can be worked in direct mode and oscillator mode connected with a high gain wide band amplifier. The testing results show that this mass-loading effect sensor possesses a better sensitivity (S=21.2ng/ppm*cm/sup 2/ in direct sensing and S=3.82ng/ppm*cm/sup 2/ in comparative sensing) and a higher linearity (/spl delta/ = /spl Delta//Sav = 3.1%) than the previous report[3].
Is there a future for the informal homecare of older people in a changing society? (2003)

The objective of the research reported here was to provide an opportunity to raise issues relevant to the ongoing debate on informal care of older people by exploring the attitudes of both men and women towards the care of dependent older people. The sample (n = 174) was drawn from age cohorts 20-39 years (n = 90) and 40-59 years (n = 84). The men and women who participated in the study were members of the general public. The self-administered survey questionnaire was designed to examine attitudes towards the informal care of older people and to determine if men and women differ not only in attitude but also in their willingness to undertake certain aspects of care, and whether the age of the respondent was likely to be a defining factor. Statistical analysis was conducted using SPSS. The results established that an overwhelming majority of women demonstrated a greater willingness to provide care to a dependent older relative.
Characterization of Boron-Incorporated Zinc Oxide Film Chemically Prepared from an Aqueous Solution (2000)

Boron‐incorporated ZnO film which had a wurtzite structure and showed optical bandgap energy of 3.3 eV was prepared chemically onto a nonconductive substrate by immersing the substrate in an aqueous solution containing a zinc nitrate and dimethylamineborane (DMAB) at 333 K. Effects of the incorporated boron on the structural, optical, and electrical characteristics of ZnO film were investigated using X‐ray diffraction, evaluation of surface morphology with an atomic force microscope, measurements of optical transmission spectra, and Hall measurement. Small amounts of boron atoms, which originated from the DMAB, were incorporated into ZnO grain and gave the lattice expansion. A pore‐free ZnO film with a smooth surface was obtained from the 0.1 mol/L DMAB solution. The ZnO film showed optical transmission as high as 80% in the visible light region and resistivity of with carrier concentration of and mobility of . It was speculated that the incorporated boron atom acted as a donor in the ZnO film. © 2000 The Electrochemical Society. All rights reserved.
Toward Controllable Self-assembly of Microstructures:  Selective Functionalization and Fabrication of Patterned Spheres (2001)

Two methods have been developed to fabricate spheres with gold caps on selective areas so that the self-assembly of these spheres can be potentially carried out in a controlled fashion. The patterned spheres are further functionalized with self-assembled groups, such as DNAs, which allows the formation of the second gold cap on the same sphere.
ZnO Nanoneedles Grown Vertically on Si Substrates by Non‐Catalytic Vapor‐Phase Epitaxy (2002)

Catalyst‐free metal–organic chemical vapor deposition (MOCVD) is used to prepare ZnO nanoneedles, grown vertically on Si substrates. Electron microscopy reveals that the nanoneedles are sharp, have uniform diameters, lengths, and densities, and high crystallinity. The photoluminescence spectrum displays a strong emission peak at 3.29 eV with a very weak deep‐level emission, indicating that the nanoneedles are of high optical quality.
Wideband Beam Steering Using a 4-Arm Spiral Array for Simultaneous Transmit and Receive (STAR) Operation (2018)

We demonstrate a wideband scanning 4-arm spiral antenna array with high transmit/receive isolation for Simultaneous Transmit and Receive (STAR). STAR increases a channel's spectral efficiency by transmitting and receiving across the full bandwidth of a channel. To our knowledge, this is the first STAR array to demonstrate scanning across GHz bandwidths. Each 4-arm spiral element is divided into two arms for transmit and two more for receive. To suppress grating lobes, the element spacing is kept at less than λ/2. A 3×3 array prototype was fabricated and measurements agree well with simulations.
PAMAM-functionalized water soluble quantum dots for cancer cell targeting (2012)

Herein, the phase-transfer reaction of quantum dots (QDs) with amine-terminated polyamidoamine (PAMAM) dendrimers with controllable ligand molar ratios was achieved. The unique properties of PAMAM allowed us to build up structurally and electrostatically stabilized water soluble QD complexes. Synthesized conjugates were characterized in terms of fluorescence and UV-Vis profiles, hydrodynamic size, number of surface dendrimer groups, and stability. Cytotoxic effects of conjugates for MCF-7, A-549 and HEP-G2 cancer cells were assessed based on cell viability using MTT assay. Cytotoxicity results were expressed as no observable adverse effect concentration (NOAEC), 50% inhibitory concentration (IC50) and total lethal concentration (TLC) values (μM). Furthermore, HER2 receptor-mediated targeting efficiency of antibody labelled P/QDs conjugates was evaluated by successful staining of MCF-7 cells with bioconjugates. Uniquely, effective cell internalization was achieved with well-characterized antibody coupled P/QDs in contrast to antibody free P/QDs conjugates. Fluorescence microscopy images demonstrated that the designed PAMAM-derivatized QDs nanoparticles show great potential in the areas of cellular imaging and targeted therapy.
Struktur von Fuerstion (1966)

Abstract Der rote Hauptfarbstoff Fuerstion (C 20 H 26 O 3 ) aus Blattdrüsen von Fuerstia africana (T.C.E. F RIES ; Fam. Labiatae) ist ein diterpenoides konjugiertes ρ‐Methylenchinon, für das die Struktur I bewiesen wird. Es zeigt strukturell Verwandtschaft mit Ferruginol. Fuerstion ist gegenüber nucleophilen und elektrophilen Reagentien sehr labil. Bei Säurebehandlung erleidet es eine Umlagerung mit Öffnung des Ringes A zwischen C‐4 und C‐5 zu einem (nicht isolierten) 1,2‐Naphtohydrochinon, das zum kristallin erhaltenen ortho ‐Naphtochinon II ( Fuerstionon ) oxydiert wurde. Mit MnO 2 − Behandlung kann aus Fuerstion das grüne, optisch aktive, sehr labile 5,6‐Dehydro‐7‐oxo‐fuerstiochinon (XV) , ein ortho ‐Benzochinon mit dem intakten C‐Gerüst des Fuerstions, gefasst werden.

Posttranslational modification and intracellular transport of mumps virus glycoproteins (1983)

Analysis of the pronase-derived glycopeptides of isolated mumps virus glycoproteins revealed the presence of both complex and high-mannose-type oligosaccharides on the HN and F1 glycoproteins, whereas only high-mannose-type glycopeptides were detected on F2. Endoglycosidase F, a newly described glycosidase that cleaves N-linked high mannose as well as complex oligosaccharides, appeared to completely cleave the oligosaccharides linked to HN and F2, whereas F1 was resistant to the enzyme. Two distinct cleavage products of F2 were observed, suggesting the presence of two oligosaccharide side chains. Tunicamycin was found to reduce the infectious virus yield and inhibit mumps virus particle formation. The two glycoproteins, HN and F, were not found in the presence of the glycosylation inhibitor. However, two new polypeptides were detected, with molecular weights of 63,000 (HNT) and 53,000 (FT), respectively, which may represent nonglycosylated forms of the glycoproteins. Synthesis of the nonglycosylated virus-coded proteins (L, NP, P, M, pI, and pII) was not affected by tunicamycin. The formation of HN oligomers and the proteolytic cleavage of the F protein were found to occur with the same kinetics. Analysis of the time course of appearance of mumps virus glycoproteins on the cell surface suggested that dimerization of HN and cleavage of F occur immediately after their exposure on the plasma membrane.

Preference Reasoning in Matching Procedures: Application to the Admission Post-Baccalaureat Platform (2017)

Because preferences naturally arise and play an important role in many real-life decisions, they are at the backbone of various fields. In particular preferences are increasingly used in almost all matching procedures-based applications. In this work we highlight the benefit of using AI insights on preferences in a large scale application, namely the French Admission Post-Baccalaureat Platform (APB). Each year APB allocates hundreds of thousands first year applicants to universities. This is done automatically by matching applicants preferences to university seats. In practice, APB can be unable to distinguish between applicants which leads to the introduction of random selection. This has created frustration in the French public since randomness, even used as a last mean does not fare well with the republican egalitarian principle. In this work, we provide a solution to this problem. We take advantage of recent AI Preferences Theory results to show how to enhance APB in order to improve expressiveness of applicants preferences and reduce their exposure to random decisions.
