Influence of Bulky Organo‐Ammonium Halide Additive Choice on the Flexibility and Efficiency of Perovskite Light‐Emitting Devices (2018)

Abstract Perovskite light‐emitting diodes (LEDs) require small grain sizes to spatially confine charge carriers for efficient radiative recombination. As grain size decreases, passivation of surface defects becomes increasingly important. Additionally, polycrystalline perovskite films are highly brittle and mechanically fragile, limiting their practical applications in flexible electronics. In this work, the introduction of properly chosen bulky organo‐ammonium halide additives is shown to be able to improve both optoelectronic and mechanical properties of perovskites, yielding highly efficient, robust, and flexible perovskite LEDs with external quantum efficiency of up to 13% and no degradation after bending for 10 000 cycles at a radius of 2 mm. Furthermore, insight of the improvements regarding molecular structure, size, and polarity at the atomic level is obtained with first‐principles calculations, and design principles are provided to overcome trade‐offs between optoelectronic and mechanical properties, thus increasing the scope for future highly efficient, robust, and flexible perovskite electronic device development.
Asymmetric homo- and hetero-bimetallic complexes of the nickel group elements. Crystal structure of [(C6F5)2Pd(µ-Cl)2Pt(PEt3)2] (1991)

By reaction between cis-[Pd(C6F5)2(PhCN)2] and cis-[MX2L2] in dichloromethane, the asymmetric homo- and hetero-bimetallic complexes [R2Pd(µ-X)2ML2] are formed (M = Ni, Pd or Pt; X = Cl, Br, I or SCN; R = C6F5 or C6H2F3-2,4,6; L = PEt3, PBu3, PPh2Me or C5H5N; L2= Ph2PCH2CH2PPh2). In chloroform solution all the gem derivatives are binuclear. The crystal structure of [(C6F5)2Pd(µ-Cl)2Pt(PEt3)2] has been solved and refined to R= 0.042 for 4241 observed reflections, confirming the existence of binuclear molecules where the Pd and Pt atoms have square-planar co-ordination [Pd–Cl 2.449(2) and 2.402(2) and Pt–Cl 2.430(2) and 2.386(2)Å].
Spring-loaded DC-contact RF MEMS switches (2004)

This paper reports on the design, fabrication, and testing of a novel spring-loaded DC-contact RF MEMS switch. Although the switch is electrostatically actuated, the on-state metal-to-metal contact is achieved through a stress-induced force. Detailed theoretical and experimental data for estimating the contact force are presented. The measured switches demonstrate an average on-state RF contact resistance of 0.5Ω and an off-state capacitance of 10 fF with an average actuation voltage of 55 V. These results demonstrate the potential of stress-originated forces for developing low-power DC-contact RF MEMS switches. © 2004 Wiley Periodicals, Inc. Int J RF and Microwave CAE 14: 345–355, 2004.
Proteomic analysis of mammalian gametes and sperm-oocyte interactions (2020)

Proteomic analysis occupies an increasingly important place in gamete and embryo biology as an independent tool of discovery and as a means of follow-up to transcriptional profiling.
P‐selectin glycoprotein‐ligand‐1 regulates pulmonary recruitment of neutrophils in a platelet‐independent manner in abdominal sepsis (2009)

These data demonstrate that PSGL-1 plays a key role in pulmonary infiltration of neutrophils as well as lung oedema associated with abdominal sepsis. Moreover, our findings suggest that PSGL-1-dependent neutrophil recruitment is independent of circulating platelets. Thus, these novel findings indicate that PSGL-1 may be a useful target to protect against sepsis-induced accumulation of neutrophils and tissue damage in the lung.
210-km bidirectional transmission system with a novel four-port interleaver to facilitate unidirectional amplification (2005)

A novel bidirectional transmission system is proposed and experimentally demonstrated using a four-port interleaver to enable unidirectional amplification. Following bidirectional transmission through 210 km of standard single-mode fibers, sensitivity variations of less than 0.2 dB, with a bit-error rate level of 10/sup -9/ at 10 Gb/s, were observed between bidirectional and unidirectional transmissions.
Phosphate liquid crystals: novel supramolecular template for the synthesis of lamellar aluminophosphates with natural form (1998)

The thermal properties ofn-alkylammonium dihydrogenphosphates, [CnH2n+1NH3+ ][H2PO4– ], where 6≤n≤18, have been investigated for the first time. It was discovered that for decylammonium (n=10), the material undergoes several polymorphic phase transitions before ultimately transforming to a smectic liquid crystal mesophase. The crystal to liquid crystal transformation of this phase was studied by in situ variable temperature polarizing optical microscopy and revealed intriguing micron dimension surface patterns. Similar thermal behaviour was observed when the material was dispersed in a polyethylene glycol non-aqueous solvent. The results have direct implications for the growth and form of surface patterned lamellar aluminophosphate morphologies prepared organo-thermally from aluminium oxide, phosphoric acid and n-alkylamines in polyethylene glycol-based solvents. Topological defects present in the precursor alkylammonium phosphate mesophase appear to be responsible for the emergence of surface textured lamellar aluminophosphate replica materials with biomimetic form. Phosphate liquid crystals represent a new class of supramolecular templates for the synthesis of a wide variety of mesostructured metal phosphates.
Dense high aspect ratio hydrogen silsesquioxane nanostructures by 100 keV electron beam lithography (2010)

We investigated the fabrication of dense, high aspect ratio hydrogen silsesquioxane (HSQ) nanostructures by 100 keV electron beam lithography. The samples were developed using a high contrast developer and supercritically dried in carbon dioxide. Dense gratings with line widths down to 25 nm were patterned in 500 nm-thick resist layers and semi-dense gratings with line widths down to 10 nm (40 nm pitch) were patterned in 250 nm-thick resist layers. The dense HSQ nanostructures were used as molds for gold electrodeposition, and the semi-dense HSQ gratings were iridium-coated by atomic layer deposition. We used these methods to produce Fresnel zone plates with extreme aspect ratio for scanning transmission x-ray microscopy that showed excellent performance at 1.0 keV photon energy.
Movement Classification based on Acceleration Spectrogram with Dynamic Time Warping Method (2017)

In this paper, we propose a movement classification model using acceleration spectrogram combined with dynamic time warping method. First, the proposed system collects data sets from a mobile device embedded acceleration sensor, and filters only coordinate data, which has an effect on the states of movements. Then the data sets in the form of frequency are converted into spectrograms. The RGB color vectors in these spectrograms are used to classify the states of movements. In order to classify these changes, a DTW algorithm is used. Finally, we validate the feasibility and applicability of the proposed model by implementing and applying it to three typical human navigational movements, namely, plain walking, going upstairs and going downstairs.
Facial Landmark Detection for Manga Images (2018)

The topic of facial landmark detection has been widely covered for pictures of human faces, but it is still a challenge for drawings. Indeed, the proportions and symmetry of standard human faces are not always used for comics or mangas. The personal style of the author, the limitation of colors, etc. makes the landmark detection on faces in drawings a difficult task. Detecting the landmarks on manga images will be useful to provide new services for easily editing the character faces, estimating the character emotions, or generating automatically some animations such as lip or eye movements. This paper contains two main contributions: 1) a new landmark annotation model for manga faces, and 2) a deep learning approach to detect these landmarks. We use the "Deep Alignment Network", a multi stage architecture where the first stage makes an initial estimation which gets refined in further stages. The first results show that the proposed method succeed to accurately find the landmarks in more than 80% of the cases.
Effect of lung T lymphocytes on fibroblasts in idiopathic pulmonary fibrosis and extrinsic allergic alveolitis. (1990)

Increased fibroblast replication and interstitial collagen accumulation occur commonly in the interstitial lung disease that progress to fibrosis. The processes controlling lung fibrogenesis are not completely understood, however. This study was designed to analyse the influence of T lymphocytes from lung tissue obtained at open lung biopsy from four patients with idiopathic pulmonary fibrosis and four patients with extrinsic allergic alveolitis on fibroblast proliferation and collagen synthesis in vitro. Lung T cell supernatants from patients with both diseases induced a moderate but significant inhibition of human lung fibroblast cell line growth. In contrast, there was a clear difference in the effect of T cells from the two groups of patients in relation to collagen production. Lung T lymphocytes from all four patients with idiopathic pulmonary fibrosis produced a substantial increase in collagen synthesis (from 371% to 514% of control values), whereas T cells from three of the four patients with extrinsic allergic alveolitis induced a significant decrease in collagen production (to 35%, 36%, and 43% of control values); in the fourth case there was an increase in collagen synthesis but this was lower than that seen with T cells from any of the patients with idiopathic pulmonary fibrosis. Peripheral T cells from six patients and control subjects caused a small increase in fibroblast proliferation and no change in collagen synthesis. The findings suggest that at least two types of interaction occur between lung T cells and fibroblasts in these disorders. A variable degree of inhibition of cell proliferation is observed in response to lung T cell supernatants from patients with both idiopathic pulmonary fibrosis and extrinsic allergic alveolitis; a substantial increase in collagen synthesis is triggered by lymphokines from patients with idiopathic pulmonary fibrosis.
Glucose-6-phosphatase in normal adult human intestinal mucosa (1992)

1. The existence of specific glucose-6-phosphatase activity in human intestinal mucosa has been somewhat controversial. 2. We have demonstrated the presence of low levels of specific glucose-6-phosphatase activity in normal human adult intestinal mucosa. Activity was found in oesophagus, stomach, duodenum and colon. 3. Immunoblot analysis using antibodies monospecific for the 36.5 kDa liver glucose-6-phosphatase catalytic subunit demonstrated that intestinal mucosa contains low levels of the glucose-6-phosphatase enzyme protein. 4. The low levels of activity together with problems of proteolysis make human intestinal biopsies unsuitable for use in the diagnosis of type 1 glycogen-storage disease.
Melanization affects susceptibility of Cryptococcus neoformans to heat and cold1 (2006)

Cryptococcus neoformans can synthesize melanin from a variety of substrates, including L-dopa (L-3,4-dihydroxyphenylalanine). Growth in minimal medium with L-dopa resulted in progressive accumulation of melanin in stationary phase cells. Melanized and non-melanized yeast cells were exposed to heat (42-47 degrees C) and cold (-20 degrees C), and the percentage of survival determined. Melanized cells were less susceptible to heat than non-melanized cells of the same age. Melanized cells from early stationary phase cultures were less susceptible to cold than non-melanized cells of the same age. However, melanized cells from late stationary phase cultures were more susceptible to cold than non-melanized cells of the same age. There was no statistical difference in susceptibility to heat and cold between melanin-deficient cells grown with and without L-dopa. These results suggest a role for melanin in protection against heat and cold.
Low Temperature Multi Effects Desalination-Mechanical Vapor Compression Powered by Supercritical Organic Rankine Cycle (2019)

Utilizing low grade heat sources such as geothermal, solar or waste heat has received a high attention in recent years. A lot of research has discussed using Organic Rankine Cycle (ORC) as subcritical or supercritical in power generation. However, very few studies extend their research in utilizing ORC in other applications such as desalination. For reverse osmosis (RO) desalination, which is considered a membrane technology, the use of supercritical-ORC in low grade heat sources is more favorable than subcritical-ORC. Thus, studies of utilizing either subcritical-ORC or supercritical-ORC for thermal desalination that use power and heat from Rankine cycle are rare or have not been done yet. Thermal desalination technologies are dominant for desalination in the Gulf Corporation Countries (GCC) and are getting more focus to treat high concentration feed and provide drinking water due to shortage of clean water in the world.\nThis study proposes a novel system that combines a supercritical-ORC with multi-effect desalination and mechanical vapor compressor (MED-MVC) for desalination using low grade heat sources at temperatures less than 150°C. A numerical model was developed, which was used to conduct performance, exergy and economic analyses under various parameters such as: salinity of the feed, temperature of motive steam and pressure of ORC. The proposed system was compared with different MED combinations with respect to specific energy consumption and unit cost of water produced.
Host expression of PD-L1 determines efficacy of PD-L1 pathway blockade–mediated tumor regression (2018)

Programmed death-1 receptor (PD-L1, B7-H1) and programmed cell death protein 1 (PD-1) pathway blockade is a promising therapy for treating cancer. However, the mechanistic contribution of host and tumor PD-L1 and PD-1 signaling to the therapeutic efficacy of PD-L1 and PD-1 blockade remains elusive. Here, we evaluated 3 tumor-bearing mouse models that differ in their sensitivity to PD-L1 blockade and demonstrated a loss of therapeutic efficacy of PD-L1 blockade in immunodeficient mice and in PD-L1- and PD-1-deficient mice. In contrast, neither knockout nor overexpression of PD-L1 in tumor cells had an effect on PD-L1 blockade efficacy. Human and murine studies showed high levels of functional PD-L1 expression in dendritic cells and macrophages in the tumor microenvironments and draining lymph nodes. Additionally, expression of PD-L1 on dendritic cells and macrophages in ovarian cancer and melanoma patients correlated with the efficacy of treatment with either anti-PD-1 alone or in combination with anti-CTLA-4. Thus, PD-L1-expressing dendritic cells and macrophages may mechanistically shape and therapeutically predict clinical efficacy of PD-L1/PD-1 blockade.
Characterization of the Rotor Magnetic Field in a Brushless Doubly-Fed Induction Machine (2009)

The large increase in wind generation could improve the final development of wind systems with brushless doubly-fed induction machines (BDFIM) as an alternative to the doubly-fed asynchronous machines. For this reason, a detailed study of several aspects of the BDFIM design, as well as of its rotor configuration, is absolutely essential. In this paper, the authors present an alternative formulation of the BDFIM operating principle in synchronous mode. Besides the basic equation of the machine operation, it presents as main advantage the precise characterization of all the magnetic field components in a BDFIM with idealized stator windings and an idealized rotor cage. Based on this formulation, the paper provides a standard that may be used to compare the fields created by different real BDFIMs. This standard has been validated by laboratory tests.

Abstract 2790: PRC2 mediated repression of SMARCA2 predicts for EZH2 inhibitor activity in tumors with SWI/SNF mutations (2017)

Abstract A synthetic lethality caused by EZH2 inhibition in the context of SNF5 mutations is supported by both preclinical and recent clinical data, however the extent of the synthetic lethal relationship in the context of other SWI/SNF subunit mutations is not well understood. We determined that a subset of SMARCA4 mutant cancer models are sensitive to EZH2 inhibition. EZH2 inhibition resulted in a heterogenous phenotypic response characterized by senescence and/or apoptosis amongst models, and further lead to tumor growth inhibition in vivo. The differential sensitivity to EZH2 inhibition was not caused by a differential pharmacodynamic effect of the drug, nor differences in basal histone methylation or PRC2 subunit levels. However, expression of the SWI/SNF subunit, SMARCA2, delineated sensitivity amongst SMARCA4 mutant models tested. Expression of SMARCA2 further delineated sensitivity amongst other SWI/SNF mutant models tested, including SNF5 and ARID1A mutants. We determined that SMARCA2 is under PRC2 mediated suppression and the derepression of SMARCA2 was necessary for apoptosis, but not senescence, in response to EZH2 inhibition. SMARCA2 has been shown to be concurrently lost in a high percentage of SNF5 mutant malignant rhabdoid tumors and SMARCA4 mutant SCCOHT tumors, however we determined that ≈15% of SMARCA4 mutant NSCLCs concurrently lose SMARCA2. Our data supports monitoring SMARCA2 expression as a predictive biomarker for EZH2-targeted therapies that are currently being developed in the context of SWI/SNF mutant cancers.

Arena (2019)

Arena is an open-access wireless testing platform based on a grid of antennas mounted on the ceiling of a large office-space environment. Each antenna is connected to programmable software-defined radios enabling sub-6 GHz 5G-and-beyond spectrum research. With 12 computational servers, 24 software defined radios synchronized at the symbol level, and a total of 64 antennas, Arena provides the computational power and the scale to foster new technology development in some of the most crowded spectrum bands. Arena is based on a clean three-tier design, where the servers and the software defined radios are housed in a double rack in a dedicated room, while the antennas are hung off the ceiling of a 2240 square feet office space and cabled to the radios through 100 ft long cables. This ensures a reconfigurable, scalable, and repeatable real-time experimental evaluation in a real wireless indoor environment. This article introduces for the first time architecture, capabilities, and system design choices of Arena, and provide details of the software and hardware implementation of the different testbed components. Finally, we showcase some of the capabilities of Arena in providing a testing ground for key wireless technologies, including synchronized MIMO transmission schemes, multi-hop ad hoc networking, multi-cell LTE networks, and spectrum sensing for cognitive radio.

Antigenic Analyses of Sugi Basic Protein by Monoclonal Antibodies; I. Distribution and Characterization of B-Cell-Tropic Epitopes of <i>Cry j I</i> Molecules (1992)

Using 23 monoclonal antibodies raised against Sugi basic protein (SBP, major allergen of Japanese cedar pollen), composed of Cry j I and Cry j II, analyses of B-cell-tropic epitopes of Cry j I were performed. The following results were obtained. (1) As far as the mAbs were used, no major cross-reactive determinants were detected between Cry j I and Cry j II molecules. (2) 21 of the 23 mAbs were specific for Cry j I, and the anti-Cry j II mAbs were classified into four groups by their fine specificities, suggesting that Cry j I bears at least four antigenic determinant regions. (3) Cry j I molecules were found to take a monomeric form in solution and to display no repeating antigenic epitopes on their surfaces. (4) Some of the determinants seemed to be located in the interior of a Cry j I molecule, and when the Ag is coated on a plastic plate, the determinants become exposed on its surface. (5) Binding of human IgE antibodies to Cry j I and Cry j II was blocked by some of the obtained mAbs, suggesting that these epitopes recognized by the mAbs might have an important role in human allergic response against the cedar pollen.
Second international workshop on organic user interfaces (2010)

Advances in display, sensor and actuator technology are changing the field of TEI, and opening new research areas. While modern interfaces have been designed for traditional planar and static display devices, next-generation UI allow digital objects to change their shape and embed displays anywhere. Fitting into the paradigm of Organic User Interfaces, these developments require us to reexamine and reevaluate some of the basic design principles and interaction styles currently used. This Second International Workshop on Organic User Interfaces will bring together experts to discuss, brainstorm and prototype next generation of user interfaces.
