All‐Nanoporous Hybrid Membranes: Redefining Upper Limits on Molecular Separation Properties (2018)

Abstract New membrane‐based molecular separation processes are an essential part of the strategy for sustainable chemical production. A large literature on “hybrid” or “mixed‐matrix” membranes exists, in which nanoparticles of a higher‐performance porous material are dispersed in a polymeric matrix to boost performance. We demonstrate that the hybrid membrane concept can be redefined to achieve much higher performance if the membrane matrix and the dispersed phase are both nanoporous crystalline materials, with no polymeric phase. As the first example of such a system, we find that surface‐treated nanoparticles of the zeolite MFI can be incorporated in situ during growth of a polycrystalline membrane of the MOF ZIF‐8. The resulting all‐nanoporous hybrid membrane shows propylene/propane separation characteristics that exceed known upper‐bound performance limits defined for polymers, nanoporous materials, and polymer‐based hybrid membranes. This serves as a starting point for a new generation of chemical separation membranes containing interconnected nanoporous crystalline phases.
Wavelet compression of digital holograms: Towards a view-dependent framework (2013)

An analysis and discussion on the relevance of various wavelet schemes for hologram compression and reconstruction when the rendering configuration makes it possible to exploit selective refinements to perform a viewpointbased degraded reconstruction. It is observed that Gabor wavelet bases have better time-frequency localization as compared to Fresnelet bases and hence are well suited for view- dependent compression techniques for hologram reconstruction.
De-crystallization of Uric Acid Crystals in Synovial Fluid Using Gold Colloids and Microwave Heating (2014)

In this study, we demonstrated a unique application of our Metal-Assisted and Microwave-Accelerated Evaporative Crystallization (MA-MAEC) technique for the de-crystallization of uric acid crystals, which causes gout in humans when monosodium urate crystals accumulate in the synovial fluid found in the joints of bones. Given the shortcomings of the existing treatments for gout, we investigated whether the MA-MAEC technique can offer an alternative solution to the treatment of gout. Our technique is based on the use of metal nanoparticles (i.e., gold colloids) with low microwave heating to accelerate the de-crystallization process. In this regard, we employed a two-step process; (i) crystallization of uric acid on glass slides, which act as a solid platform to mimic a bone, (ii) de-crystallization of uric acid crystals on glass slides with the addition of gold colloids and low power microwave heating, which act as "nano-bullets" when microwave heated in a solution. We observed that the size and number of the uric acid crystals were reduced by >60% within 10 minutes of low power microwave heating. In addition, the use of gold colloids without microwave heating (i.e. control experiment) did not result in the de-crystallization of the uric acid crystals, which proves the utility of our MA-MAEC technique in the de-crystallization of uric acid.
TIME-INTERLEAVED DELTA-SIGMA MODULATOR FOR WIDEBAND DIGITAL GHZ TRANSMITTERS DESIGN AND SDR APPLICATIONS (2011)

This paper presents a development of a wideband delta- sigma modulator for fully digital GHz transmitters. The fully digital RF transmitter is developed as a promising solution for software deflned radio (SDR) terminals and applications. The fully digital transmitter consists of a delta-sigma modulator, a high- speed multiplexer and a switching-mode power amplifler. The speed limitation of delta-sigma modulator is the main limitation to increase the signal bandwidth in fully digital transmitters. In this paper, the bandwidth of the fully digital transmitter is increased 8 times using parallel processing time-interleaved architecture, while maintaining the same signal quality. This architecture was implemented on FPGA and tested for difierent standards (WiMAX and LTE) with a signal bandwidth up to 8MHz. The concept was assessed in terms of SNDR by using a difierential logic analyzer at the output of FPGA, and the SNDR was found to be around 60dB.
Screening of Nijmegen Breakage Syndrome 1 Mutations in Four Unrelated Families by Polymerase Chain Reaction Using Sequence-Specific Primers (2006)

Nijmegen breakage syndrome (NBS) is an autosomal recessive disorder characterized by a marked predisposition to lymphoreticular malignancies. The rarity of the disease and the presence, in several cases, of a mild clinical phenotype make diagnosis difficult. The underlying gene, NBS1, consists of 16 exons and encodes nibrin, a member of the hMRE11/hRAD50/hNBS1 protein complex. In addition to the "Slavic mutation," 657del5, identified in more than 100 patients with NBS, 9 other mutations have been found in families of different ethnic origin. We have developed a polymerase chain reaction (PCR) method to rapidly detect the private mutations, 742insGG and 835del4, in exon 7 and the 900del25 mutation in exon 8 of the NBS1 gene. In particular, we designed NBS1-specific primers for wild-type and mutated alleles, and optimized a specific PCR protocol for each mutation. We used this method to analyze 4 unrelated NBS families, 3 from Italy and 1 from Morocco. We believe it could be a useful tool for: (1) confirming the NBS diagnosis in the presence of clinical signs of the disease; (2) identifying NBS heterozygotes and performing prenatal diagnosis in families with affected members; and (3) screening selected populations in which the frequency of NBS might be higher because of a founder effect.
Local Optical Limiting Devices Based on Photoaddressed Spatial Light Modulators, Using Ferroelectric Liquid Crystals (1997)

Abstract The devices for local light discrimination in the field of view of eye or light-sensitive devices (videocamera, etc.) are discussed, using optically addressed spatial light modulators. The deformed helical ferroelectric (DHF) effect in FLC's is considered. Different optical schemes of local optical limiting devices with corresponding driving conditions are discussed and the transmission of devices in dependence on FLC parameters (molecular tilt angle) is estimated. The operation ofdevice prototype for local protection of video camera using OASLM and FLC shutter is shown.

This paper presents a high-efficiency 2.45 GHz rectenna which can harvest low input RF power effectively. An antenna with a simple structure and high gain is directly matched to the rectifying circuit which eliminates the low-pass filter between the antenna and rectifying circuit. The measured peak gain of the antenna is 8 dBi. The rectenna efficiency can reach 50% with input power of 0 dBm.
Low-Complexity Switch Network for Reconfigurable LDPC Decoders (2009)

In this paper, we propose an efficient low-complexity switch network design for reconfigurable low-density parity-check (LDPC) decoders. The proposed architecture leads to significant reductions in hardware complexity. Since the structured quasi-cyclic (QC) LDPC codes for most modern wireless communication systems include multiple code rates, various block lengths, and different sizes of submatrices, a reconfigurable LDPC decoder is desirable and the barrel shifter needs to be programmable. The Benes network cannot be optimized as the barrel shifter for a reconfigurable LDPC decoder when the input size of barrel shifter is not a power of 2. Also, it is not trivial to generate all the control signals on-the-fly for numerous 2 × 2 switches in the switch network. In this paper, a novel low-complexity switch network design is proposed, which can be used efficiently when the input size of barrel shifters is not a power of 2. Furthermore, we propose a novel algorithm to generate all the control signals, which can be implemented with a small size of lookup table (LUT) or a simple combination logic on-the-fly, using the properties that both the full-size switch network can be broken into two half-size switch networks and the barrel shifters for the structured QC LDPC decoders require only cyclic shifts. Compared with conventional Benes networks using a dedicated LUT or a complicated signal generating algorithm, the proposed architectures achieve significant hardware reductions in implementing the barrel shifters for reconfigurable LDPC decoders. In synthesis result using the TSMC 0.18-¿m standard cell CMOS technology, the proposed switch network for a reconfigurable LDPC decoder of IEEE 802.16e and IEEE 802.11n can be implemented with an area of 0.772 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , which leads to a significant area reduction.
Influence of Operating Conditions on Deposition Rate and Smoothness of Electrolytic Aluminum Foil Using Chloroaluminate Ionic Liquids (2021)

The ionic liquid comprised of anhydrous aluminum chloride (AlCl 3 ) and 1-ethyl-3-methylimidazolium chloride (EMIC) has attracted attention as an electrolyte for Al electrolysis. We have investigated the influence of the operating conditions on the deposition rate and the surface roughness of electrolytic Al foil by using the AlCl 3 -EMIC melt with/without 20 mmol dm −3 of an 1,10-phenanthroline anhydrate (OP) additive as the electrolyte. The cross-sectional SIM images revealed that the increase in the operating temperature affected the foil thickness and the OP addition affected the smoothness. At the operating temperature of 50 °C and the current density of 52.6 mA cm −2 , the current efficiency was 90% or more and the deposition rate was about 0.9 μ m min −1 regardless of the OP addition. An AFM image revealed that the surface roughness value of the Al foil obtained on the Ti plate substrate from the melt with the OP additive at 50 °C was 45.8 nm at the current density of 52.6 mA cm −2 . The XRD patterns showed that the orientations of the (200) reflections became strong by the OP addition. A smooth Al foil was obtained even at a high current density by increasing the operating temperature and adding OP to the melt.
Model Based Design of a Novel Process for Nitrogen Removal from Concentrated Flows (1999)

A new process for biological nitrification was developed that is operated in a single aerated reactor at relatively high temperature and pH. This process, termed SHARON, was designed to achieve substantial ammonia conversion at high reaction rates for relatively concentrated flows, rather than to meet strict effluent standards. First large scale applications that are under construction now, aim at treating reject water from a sludge digestion unit. The SHARON process operates without sludge retention, and ammonium oxidation is stopped at nitrite, which saves on aeration costs. Denitrification is used as a cheap means to control the pH. Under typical conditions, no heating is necessary due to the heat production by the reactions. Overall processing costs are less than 50% of other techniques. This contribution focuses on model development for process design calculations at full scale. Underlying kinetic principles, and especially their pH dependency, are highlighted as well.
Development of a novel series of (2-quinolinylmethoxy)phenyl-containing compounds as high-affinity leukotriene D4 receptor antagonists. 4. Addition of chromone moiety enhances leukotriene D4 receptor binding affinity (1991)

The combination of the benzopyran-4-one ring, a moiety found in the prototype leukotriene antagonist, FPL 55,712, with the (2-quinolinylmethoxy)phenyl group led to a significant increase in leukotriene receptor binding affinity. This modification resulted in a 10,000-fold improvement in binding affinity compared to FPL 55,712. Compound 7 (RG 12553), with a Ki value of 0.1 nM, has higher affinity than the natural agonist LTD4 and is one of the most potent LTD4 antagonists reported. The structure-activity relationships of this series of potent leukotriene antagonists are discussed.
Effect of IL-22 on intestinal stem cells, GVHD-related tissue damage, and GVL. (2012)

6539 Background: Intestinal graft vs. host disease (GVHD) is a major complication of allogeneic bone marrow transplantation (allo-BMT). Strategies to limit GVHD by selective promotion of epithelial regeneration in the absence of immunosuppression are largely unknown. Methods: We investigated the role of IL-22 in allo-BMT by utilizing wild type and IL-22 knockout (KO) mice as donors or recipients in allo-BMT. Results: We found that administration of an anti-IL-22 neutralizing antibody to allo-BMT recipients during the first month post-BMT led to increased GVHD mortality, indicating that IL-22 functioned to reduce GVHD severity post-BMT. In contrast, use of IL-22 KO donor T cells did not impair their ability to eliminate A20 lymphoma cells upon tumor challenge, thus indicating that IL-22 was not essential for donor T cells to mediate graft vs. lymphoma (GVL) responses. BMT with WT donors and recipients indicated that IL-22 levels in small and large intestine were increased after BMT and after radiation injury (RI) without BMT. IL-22 upregulation after RI was dependent on the presence of IL-23p40. Although intestinal IL-22 levels were increased after T cell-depleted (TCD) BMT, intestinal IL-22 was reduced by GVHD, as IL-22 production was mediated by host-derived innate lymphoid cells (ILC) that were eliminated by GVHD. Furthermore, host-derived IL-22 was critical for reduction of GVHD morbidity, mortality, and intestinal pathology. GVHD in IL-22 KO mice led to increased apoptosis in epithelial crypts where the intestinal epithelial stem/progenitor cell niche is located. Immunohistochemistry and immunofluorescence demonstrated IL-22 receptor expression on intestinal stem cells (ISC) and progenitors. Allo-BMT in Lgr5-LacZ reporter mice indicated that ISC were targeted by GVHD, and GVHD in IL-22 KO mice led to dramatic ISC depletion. Conclusions: IL-22 is critical for protection of host epithelium during GVHD and critical for protection of ISC, and it does not contribute to donor T cell GVL responses. These findings may have broad relevance for protection of ISC and intestinal epithelium in clinical GVHD and other inflammatory intestinal diseases, and may be useful for clinical separation of pathologic GVH and therapeutic GVL responses.
The nonlinear coefficient d 36 of CdSiP 2 (2009)

The new nonlinear crystal for the mid-IR CdSiP<sub>2</sub> was discovered only very recently but the interest in this chalcopyrite is enormous because it possesses most of the attractive properties of the related ZnGeP<sub>2</sub> but allows in addition pumping at 1064 nm without two-photon absorption and uncritical phase-matching for 6 μm generation with maximized effective nonlinearity. The last feature is due to the fact that this crystal is negative uniaxial in contrast to ZnGeP<sub>2</sub> which shows positive birefringence. We now measured its nonlinear coefficient using SHG of femtosecond pulses generated near 4.6 μm from a seeded KNbO<sub>3</sub> optical parametric amplifier. The SHG efficiency was compared for uncoated samples of CdSiP<sub>2</sub> and ZnGeP<sub>2</sub>, both ≈0.5 mm thick, in the low conversion limit (<10% internal conversion efficiency) which justifies the use of the plane wave approximation. Taking into account the experimentally determined phase-matching angles for type-I SHG (oo-e type in CdSiP<sub>2</sub> and ee-o type in ZnGeP<sub>2</sub>), which were in good agreement with the existing Sellmeier approximations, we arrived at d<sub>36</sub>(CdSiP<sub>2</sub>)~d<sub>36</sub>(ZnGeP<sub>2</sub>) which is rather unexpected having in mind the larger band-gap of CdSiP<sub>2</sub>. The reliability of the measurement was tested at the same wavelength by comparing ZnGeP<sub>2</sub> with HgGa<sub>2</sub>S<sub>4</sub> which led to the result d<sub>36</sub>(ZnGeP<sub>2</sub>)~3d<sub>36</sub>(HgGa<sub>2</sub>S<sub>4</sub>), in very good agreement with previous estimations.
Novel hybrid thin film silicon solar cell and module (2003)

An initial efficiency of 14.7% (Jsc=14.4 mA/cm/sup 2/, Voc=1.41 V, FF=72.8%) has been achieved for a-Si:H/transparent inter-layer/microcrystalline Si solar cell (total area of 1 cm/sup 2/). The short circuit current (Jsc) was enhanced by the introduction of transparent interlayer, namely internal light trapping. The highest Jsc of 15 mA/cm/sup 2/ was obtained by this internal light trapping. It was also found that total spectral response is enhanced by both selecting and adjusting the appropriate materials and preparation conditions of above mentioned transparent inter-layer. An initial aperture efficiency of 13.2% has been achieved for 910/spl times/455 mm/sup 2/ a-Si/microcrystalline Si thin film integrated large area solar cell module. The higher efficiency potential of thin film three stacked cell is also addressed by using new technology of internal light trapping.
Joint phase noise and frequency offset estimation and mitigation for optically coherent QAM based on adaptive multi-symbol delay detection (MSDD) (2012)

This paper extends our prior coherent MSDD Carrier Recovery system from QPSK to QAM operation and also characterizes for the first time the Carrier Frequency Offset (CFO) mitigation capabilities of the novel MSDD for QAM systems. We introduce and numerically investigate the performance of an improved MSDD carrier recovery system (differing from the one disclosed in our MSDD for QPSK prior paper), automatically adapting to the channel statistics for optimal phase-noise mitigation. Remarkably, we do not require a separate structure to estimate and mitigate CFO, but the same adaptive structure originally intended for phase noise mitigation is shown to also automatically provide frequency offset estimation and recovery functionality. The CFO capture range of our system is in principle infinite, whereas prior CFO mitigation systems have CFO capture ranges limited to a small a fraction of the baud-rate. When used for 16-QAM with coherent-grade lasers of 100 KHz linewidth, our MSDD system attains the best tradeoffs between performance and complexity, relative to other carrier recovery systems combining blind-phase-search with maximum likelihood detection. We also present additional MSDD phase-noise recovery system variants whereby substantially reduced complexity is traded off for slightly degraded performance. Our MSDD system is able to switch "on-the-fly" to various m-QAM constellation sizes, e.g. seamlessly transition between 16-QAM and QPSK, which may be useful for dynamically adaptive optical networks.
Wide-Band Impedance Matching:&lt;tex&gt;$H^infty$&lt;/tex&gt;Performance Bounds (2004)

This paper presents the first implementation of Helton's H/sup /spl infin// approach to wide-band impedance matching. The prototypical problem is to maximize the transducer power gain uniformly over an operating band for a load connected to a generator by a lossless two-port. The H/sup /spl infin// approach computes the maximum transducer power gain attainable by any lossless two-port uniformly over the operating band. This maximum gain is computed for Fano's classic RLC circuit and an high-frequency antenna represented by measured reflectance data.
Comparison Study on SS and Double-Sided LCC Compensation Topologies for EV/PHEV Wireless Chargers (2015)

This paper compares the characteristics of the series–series and double-sided Inductor-Capacitor-Capacitor (LCC) compensation topologies for electric vehicle (EV) wireless chargers. Both the well-tuned and mistuned topologies for the two compensation methods are analyzed in detail. The mistuning considered here is mainly caused by the variations of the relative position between the primary and secondary sides. The output power displacements caused by mistuning are compared for both compensation topologies, as well as the impacts of the load variations on the performances of the mistuned topologies. The voltage and current stresses on components are also studied. The comparative result shows that the double-sided LCC compensation topology is less sensitive to mistuning. A double-sided LCC-compensated EV wireless charger system with up to 7.7-kW output power is built to verify the analysis results. A peak efficiency of 96% from dc power source to battery load is achieved.

Combined therapy with bisphosphonate and chemotherapy may be useful for small cell lung cancer patients with multiple organ metastases including bone metastasis.
Effect of temperature upon adhesion formation in a laparoscopic mouse model (2004)

Hypothermia reduces pneumoperitoneum-enhanced adhesion formation, which supports hypoxia as a driving mechanism, since hypothermia decreases the toxic effects of hypoxia and of the ischaemia-reperfusion process. These data could open up new possibilities for adhesion prevention in laparoscopic surgery.
Safety and Immunogenicity of Haemophilus influenzae Type b Polysaccharide-Diphtheria Toxoid Conjugate Vaccine (PRP-D) in Infants (1987)

Safety and immunogenicity of a Haemophilus influenzae type b polysaccharide-diphtheria toxoid conjugate vaccine (PRP-D) was evaluated in infants seven to 14 months of age. PRP-D (80% of subjects) or saline placebo (20%) was randomly and blindly administered (two doses separated by two months). Incidence of mild reactions lasting less than 48 hr did not differ significantly between the placebo and vaccine recipients. Preimmunization levels of antibody to PRP were less than or equal to 0.15 micrograms/ml in 97% of subjects. A twofold increase in antibody concentration occurred in 88% of subjects following the first dose and in 99% following the second dose of vaccine. No change occurred in placebo recipients. Mean level of antibody and percentage of subjects with levels of antibody greater than or equal to 1 microgram/ml after vaccination increased with increasing age. Responses were related to vaccine lot but not to sex, race, or geographic location. Two doses of PRP-D in infants seven months of age and older induced antibody levels equal to or greater than levels in infants 24 months of age given the polysaccharide alone.
From Captions to Visual Concepts and Back (2014)

This paper presents a novel approach for automatically generating image descriptions: visual detectors, language models, and multimodal similarity models learnt directly from a dataset of image captions. We use multiple instance learning to train visual detectors for words that commonly occur in captions, including many different parts of speech such as nouns, verbs, and adjectives. The word detector outputs serve as conditional inputs to a maximum-entropy language model. The language model learns from a set of over 400,000 image descriptions to capture the statistics of word usage. We capture global semantics by re-ranking caption candidates using sentence-level features and a deep multimodal similarity model. Our system is state-of-the-art on the official Microsoft COCO benchmark, producing a BLEU-4 score of 29.1%. When human judges compare the system captions to ones written by other people on our held-out test set, the system captions have equal or better quality 34% of the time.
A wideband 60 GHz class-E/F<inf>2</inf> power amplifier in 40nm CMOS (2015)

This paper presents a fully integrated 60 GHz power amplifier in 40nm CMOS that reaches the highest reported product of power-added efficiency and bandwidth. It is achieved through low/moderate coupling-factor transformers in the preliminary stages and a proper second harmonic termination of the output stage, such that it can operate as a class-E/F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> switched-mode PA at the saturation point. The three-stage PA delivers 17.9dBm saturated output power with 20% peak PAE. It demonstrates a bandwidth of 9.7 GHz with a peak gain of 21.6 dB.
