Purification, characterisation and cDNA sequence of tRNA nucleotidyltransferase from Lupinus albus (1994)

This study presents the development and optimization of La@SnO<sub>2</sub>-CaO composite catalysts for efficient photocatalytic degradation of malachite green dye in aqueous solutions under UV-vis light irradiation. The catalysts were prepared via conventional incipient-wetness impregnation and thoroughly characterized using advanced analytical techniques, including X-ray diffraction, Fourier transform infrared spectroscopy, UV-vis diffuse reflectance spectroscopy, N<sub>2</sub> adsorption-desorption analysis, and scanning electron microscopy. To optimize photodegradation efficiency, the effects of three independent factors were systematically investigated using response surface methodology: Temperature, pH, and Sn/Ca molar ratio. Our results reveal optimal conditions for maximum dye degradation: pH 7, Sn/Ca molar ratio of 0.33, and a process time of 35 min, resulting in a maximum photodegradation efficiency of 98.80% for malachite green dye. Notably, visible light exhibited a more pronounced effect on dye degradation compared to UV light over time, with visible light achieving 25% greater dye removal after 60 min of illumination. Furthermore, the catalyst showed excellent recyclability, retaining 85% of its initial activity after five consecutive cycles. These findings contribute significantly to the development of sustainable methods for dye removal from wastewater and highlight the potential of La@SnO<sub>2</sub>-CaO composite catalysts in environmental remediation processes, particularly in treating textile industry effluents.
Modeling and analysis of DC-link voltage for three-phase four-wire two-stage micro-inverter (2014)

DC-link voltage control plays a key role for two-stage micro-inverter application. Modeling &analysis of dc-link voltage is investigated in this paper. The first-stage circuit employs transient maximum power point tracking method to realize fast MPP tracking without causing output distortion and dc-link variation. In order to keep dc-link voltage constant, injecting current to grid varies with the output of a positive feedback of dc-link voltage regulator at steady situation. Two disturbances to cause dc-link constant are investigated and small signal model of dc-link voltage is also built while considering dynamic response. Followed by the small signal model of dc-link voltage, the dc-link capacitance is also calculated. The performance of dc-link voltage control is verified by experimental results based on a 400 watt two-stage three-phase four-wire prototype with grid-connected, the input voltage from 35V to 60V, dc-link voltage 400Vdc and AC output voltage 110V RMS.
Lymphocyte predominant cells detect Moraxella catarrhalis-derived antigens in nodular lymphocyte-predominant Hodgkin lymphoma (2020)

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare lymphoma of B-cell origin with frequent expression of functional B-cell receptors (BCRs). Here we report that expression cloning followed by antigen screening identifies DNA-directed RNA polymerase beta' (RpoC) from Moraxella catarrhalis as frequent antigen of BCRs of IgD<sup>+</sup> LP cells. Patients show predominance of HLA-DRB1*04/07 and the IgVH genes encode extraordinarily long CDR3s. High-titer, light-chain-restricted anti-RpoC IgG1/κ-type serum-antibodies are additionally found in these patients. RpoC and MID/hag, a superantigen co-expressed by Moraxella catarrhalis that is known to activate IgD<sup>+</sup> B cells by binding to the Fc domain of IgD, have additive activation effects on the BCR, the NF-κB pathway and the proliferation of IgD<sup>+</sup> DEV cells expressing RpoC-specific BCRs. This suggests an additive antigenic and superantigenic stimulation of B cells with RpoC-specific IgD<sup>+</sup> BCRs under conditions of a permissive MHC-II haplotype as a model of NLPHL lymphomagenesis, implying future treatment strategies.
Cloud computing provisioning over Passive Optical Networks (2012)

This paper presents a novel network architecture to provide cloud computing using Passive Optical Networks (PONs). It promotes a new application model of PON, especially for the design and development of next generation PONs. The attractive features include data-plane provisioning in addition to traditional transmission-pipe functionality, a new way to subsidize access network deployment investment, as well as high-speed fiber optic resource virtualization. We investigate this new architecture's feasibility by studying PON processing, storage and interconnection capabilities. Based on the feasibility study, we further explore the infrastructure as a service (IaaS) provisioning over PONs. The PON cloud performance is evaluated from two aspects: compute capability and storage capacity. Detailed analysis shows that cloud capability is determined by the PON configuration. Relevant parameters are ONU memory capacity, ONU CPU processing capability, OLT memory capacity, OLT CPU processing capability, PON port split, PON port density, OLT card density. Our result shows that PON cloud is an attractive value-added implementation of high-speed optic-fiber access systems.

A Descriptive Study of Bacterial Load of Full-Thickness Surgical Wounds in Dermatologic Surgery (2011)

This study provides novel insights into the bacterial dynamics of dermatologic surgery-induced wounds and the variation of this over time. The results highlight the potential relevance of quantifying bacterial loads, as well as determining specific types of bacteria, in dermatologic surgery.
Recombinant allergen-based monitoring of antibody responses during injection grass pollen immunotherapy and after 5 years of discontinuation (2011)

The results from our observational study demonstrate that only SCIT but not anti-inflammatory treatment induces allergen-specific IgG and reduces boosts of allergen-specific IgE production but that one SCIT course was not sufficient to achieve long-term immunological and clinical effects.
Atomic structure and lattice defects in nanolaminated ternary transition metal borides (2016)

We use analytical aberration-corrected high-resolution scanning transmission electron microscopy to image the atomic structure of the layered ternary transition metal (M) borides, Cr2AlB2, Fe2AlB2, and MoAlB. In these ternaries, MB layers and Al single or double atomic layers are interleaved. The atomic positions of the M elements and Al are clearly resolved by Z-contrast images. The following structural defects are also found and described herein: a 90° twist boundary along [010] in Cr2AlB2, a tilt boundary in Fe2AlB2, and Mo2AlB2-like stacking faults in MoAlB, where some of the MB-based structures are intercalated by one (instead of two) Al layer(s).

Thermolysis of an Azide‐Phenolic Resin Composite Film and Its Use as an Antireflective Bottom Layer in the Three‐Layer Resist Process (1987)

Thermolysis of a composite film formulated from a cresol novolak resin and a novel bis‐azide cross‐linking reagent, 1‐(4‐azidobenzylidene)‐3‐(α‐hydroxy‐4‐azidobenzyl)indene (I), is compared with its photolysis. The bis‐azide decomposes on heating above 130°C or on UV exposure to form primary and secondary amines as main products which cause a red shift in the UV‐visible absorption spectrum. The amines fixed in the novolak resin can be regarded as nonvolatile absorbing dyes. The cross‐linking of the novolak is accompanied by bis‐azide thermolysis while oxidative cross‐linking of the undoped novolak occurs in thermolysis above 200°C. This thermolytic property of the bis‐azide/novolak film is found to be well suited as an antireflective bottom layer in the three‐layer resist process. The use of the absorbing film as a bottom layer eliminates the reflected light from substrate surfaces during the exposure of the top layer resist, reducing linewidth variations in top resist patterns.
Automatic assessment of the quality of patient positioning in mammography (2013)

Quality assurance has been recognized as crucial for the success of population-based breast cancer screening programs using x-ray mammography. Quality guidelines and criteria have been defined in the US as well as the European Union in order to ensure the quality of breast cancer screening. Taplin et al. report that incorrect positioning of the breast is the major image quality issue in screening mammography. Consequently, guidelines and criteria for correct positioning and for the assessment of the positioning quality in mammograms play an important role in the quality standards. In this paper we present a system for the automatic evaluation of positioning quality in mammography according to the existing standardized criteria. This involves the automatic detection of anatomic landmarks in medio- lateral oblique (MLO) and cranio-caudal (CC) mammograms, namely the pectoral muscle, the mammilla and the infra-mammary fold. Furthermore, the detected landmarks are assessed with respect to their proper presentation in the image. Finally, the geometric relations between the detected landmarks are investigated to assess the positioning quality. This includes the evaluation whether the pectoral muscle is imaged down to the mammilla level, and whether the posterior nipple line diameter of the breast is consistent between the different views (MLO and CC) of the same breast. Results of the computerized assessment are compared to ground truth collected from two expert readers.
Improved rf cavity search for halo axions (2004)

The axion is a hypothetical elementary particle and cold dark matter candidate. In this rf cavity experiment, halo axions entering a resonant cavity immersed in a static magnetic field convert into microwave photons, with the resulting photons detected by a low-noise receiver. The ADMX Collaboration presents new limits on the axion-to-photon coupling and local axion dark matter halo mass density from a rf cavity axion search in the axion mass range $1.9--2.3\ensuremath{\mu}\mathrm{eV},$ broadening the search range to $1.9--3.3\ensuremath{\mu}\mathrm{eV}.$ In addition, we report first results from an improved analysis technique.
Yield-driven near-threshold SRAM design (2007)

Voltage scaling is desirable in SRAM to reduce energy consumption. However, commercial SRAM is prone to functional failures when Vdd is scaled. Several SRAM designs scale Vdd to 200-300 mV to minimize energy per access, but these designs do not consider SRAM robustness, limiting them to small arrays and sensor type applications. We examine the effects on area and energy for a differential 6 T, single-ended 6 T with power rail collapsing and an 8 T bitcell as Vdd is scaled and the bitcells are sized appropriately to maintain robustness. SRAM robustness is examined using importance sampling to reduce simulation runtime. At high voltages, the differential 6T bitcell is the smallest for the same failure rate, but the 8 T bitcell is smaller when Vdd is scaled below 450 mV. For Vdd below Vth, bitcells must be sized greatly to retain robustness and large arrays become impractical. The differential 6 T and 8 T designs have the lowest dynamic energy consumption, and the single-ended 6 T design has the lowest leakage. The supply voltage for minimum energy operation depends on cache configuration and can be well above Vth for large caches with low dynamic activity.
Large-Volume Infusions into the Brain: A Comparative Study of Catheter Designs (2018)

Mucosal antimicrobial protection toward enteroaggregative Escherichia coli infection is modulated by dietary tryptophan through an IL17-dependent mechanism (MUC4P.846) (2014)

Abstract Enteroaggregative E. coli (EAEC) is a predominant extracellular pathogen that causes inflammatory diarrhea in individuals worldwide, especially in persons suffering from malnutrition. We previously reported that protein-energy malnutrition abrogates protective Th17-dependent antimicrobial immunity in a murine model of EAEC infection. However, mechanisms whereby malnutrition enhances host-susceptibility to EAEC colonization remain unreported. This study presents evidence that tryptophan is crucial for antibacterial protection against EAEC infection. Mice fed tryptophan-free diet had reduced antimicrobial peptide production coinciding with significantly high pathogen levels. Likewise, bacterial burden occurred in a dose dependent manner when mice were supplemented with glycly-L-tryptophan dipeptide. Low serum tryptophan directly correlated with hampered gene expression levels of cytokines regulating effector IL-17A responses (e.g. IL-23 and IL-6). Mechanistically, orally administered tryptophan enhanced IL-17A and IL-17C production at the colonic and ileal mucosa facilitating antimicrobial defense and protection against EAEC colonization. IL17a-/- and IL17ra-/- mice receiving nourished diets or tryptophan supplements were unable to recover from disease due to impaired intestinal epithelial barrier function. Thus, our data suggests that tryptophan modulates IL17-dependent antimicrobial responses and is required for preventing EAEC colonization and pathogenic disease.
Finite-element simulation of coupled characteristics of ceramic multilayer capacitors under transient electrical loading (2002)

Simulation methods are more and more employed to investigate characteristics and behavior of complex electronic devices. The results can be used to obtain reliability data and reasons for failures and to investigate possibilities for device optimizations. One challenge in these simulations is the consideration of coupled and nonlinear material characteristics, e.g. the piezoelectric coupling in BaTiO/sub 3/ based capacitor materials. In our work we present the modeling of the nonlinear coupled behavior of a ceramic multilayer capacitor (MLC) as model for other multilayer structures under transient large signal operating conditions. The electrical, mechanical, and thermal stress distribution are identified for the highest occurring voltage when the MLC is used as a bypass capacitor in an under damped circuit.
Canonical Correlation Analysis with Common Graph Priors (2018)

Canonical correlation analysis (CCA) is a well-appreciated linear subspace method to leverage hidden sources common to two or more datasets. CCA benefits are documented in various applications, such as dimensionality reduction, blind source separation, classification, and data fusion. However, the standard CCA does not exploit the geometry of common sources, which may be deduced from (cross-) correlations, or, inferred from the data. In this context, the prior information provided by the common source is encoded here through a graph, and is employed as a CCA regularizer. This leads to what is termed here as graph CCA (gCCA), which accounts for the graph-induced knowledge of common sources, while maximizing the linear correlation between the canonical variables. When the dimensionality of data vectors is high relative to the number of vectors, the dual formulation of the novel gCCA is also developed. Tests on two real datasets for facial image classification showcase the merits of the proposed approaches relative to their competing alternatives.
Abnormal (Hydroxy)proline Deuterium Content Redefines Hydrogen Chemical Mass (2022)

Analyzing the δ<sup>2</sup>H values in individual amino acids of proteins extracted from vertebrates, we unexpectedly found in some samples, notably bone collagen from seals, more than twice as much deuterium in proline and hydroxyproline residues than in seawater. This corresponds to at least 4 times higher δ<sup>2</sup>H than in any previously reported biogenic sample. We ruled out diet as a plausible mechanism for such anomalous enrichment. This finding puts into question the old adage that "you are what you eat".
Mini‐Magnetospheric Plasma Propulsion: Tapping the energy of the solar wind for spacecraft propulsion (2000)

Mini‐Magnetospheric Plasma Propulsion is a potentially revolutionary plasma propulsion concept that could enable spacecraft to travel out of the solar system at unprecedented speeds of 50 to 80 km s −1 or could enable travel between the planets for low power requirements of ∼l kW per 100 kg of payload and ∼0.5 kg fuel consumption per day for acceleration periods of several days to a few weeks. The high efficiency and specific impulse attained by the system are due to its utilization of ambient energy, in this case the energy of the solar wind, to provide the enhanced thrust. Coupling to the solar wind is produced through a large‐scale magnetic bubble or mini‐magnetosphere generated by the injection of plasma into the magnetic field supported by solenoid coils on the spacecraft. This inflation is driven by electromagnetic processes, so that the material and deployment problems associated with mechanical sails are eliminated.
P1526Exercise capacity in treated hypertensives (2018)

Preventive cardiology 289 aged men (mean age 567 years) without manifest cardiovascular/atherosclerotic disease. Results: In multivariable models, both HDL-C and TT are positively correlated with brachial FMD, penile PSV and negatively correlated with carotid-femoral PWV and cIMT All patients were stratified into those with low HDL-C level (40 mg/dl) and those with high HDL and further subdivided according to presence/absence of testosterone deficiency (TT<3.5 ng/ml). The subgroup of patients with low HDL-C/low TT (n=44) exhibited significantly lower age -adjusted brachial FMD and penile PSV (overall P<0.01, by ANCOVA, figures A-B) and higher PWV and cIMT (overall P<0.05, by ANCOVA, figures C-D) as compared with the subgroups of low HDL-C/high TT, high HDL-C /low TT and high HDL-C/high TT (overall P<0.05, by ANCOVA).
Flexibility-Enhanced HTS System for Disaster Management: Responding to Communication Demand Explosion in a Disaster (2017)

Natural disaster interrupts essential services due to the facility damage and lack of power supply. Especially, significant communication outages occurs in a wide area for hierarchical network such as cellular communication system in case core nodes are damaged or congested. In order to provide alternative communication ability, high throughput satellite (HTS) is one of the ideal candidates for disaster management because it provides operative communication for a wide area regardless of the availability of regular terrestrial infrastructures. However, conventional HTS relays data with predetermined beam bandwidth and connection, it is inefficient when the communication demand explodes in a disaster area. Therefore, this paper proposes novel frequency allocation technique with flexibility-enhanced HTS system for disaster management to respond to communication demand explosion. While related research works consider user-link resource allocation, this paper focuses on how to control feeder-link and user-link bandwidths in case that the both links can be assigned at continuous frequency such as Ka-band. Furthermore, our proposal addresses resilient satellite network by selecting optimum gateway based on the traffic demand at neighboring user-link beams. The effectiveness of our proposal is verified through simulation results.
Design of resonance damping via control synthesis (2015)

Dampers are widely used in power electronics to damp resonances, in order to reduce device stress, power loss, and electromagnetic interference. In this paper we formulate the damping problem so as to expose the fundamental tradeoff between damping amplitude peaks and minimizing power dissipation, and then use a constrained optimization approach to compute optimal Pareto frontier as a function of damper order. We use the procedure to demonstrate the diminishing returns of increasing damper order using a simple filter example, and then we demonstrate the power of the method for multiport converters. In particular, we show that using the constrained optimization procedure dramatically outperforms the standard port-by-port method.
Transferrin receptor 1 mRNA is downregulated in placenta of hepcidin transgenic embryos (2004)

We have previously shown that hepcidin transgenic embryos are severely anemic and die around birth. Here, we report that embryonic hepcidin transgene expression decreases transferrin receptor 1 (TfR1) mRNA level in placenta, as shown by cDNA microarray analysis and quantitative RT-PCR, by a mechanism which is independent of placenta iron content and iron responsive element/iron regulatory protein (IRE/IRP) activity. On the contrary, iron injections into pregnant mothers result in increased placenta iron and ferritin content, and reduced IRE binding activity of IRP1 leading to decreased TfR1 mRNA level. Taken together, these results suggest that hepcidin action on placenta is mostly through transcriptional downregulation of the iron uptake machinery.
Two-stage Sagnac demultiplexer (2003)

Cascading a semiconductor optical amplifier (SOA)-based Sagnac interferometer with a second Sagnac stage allows significant improvement in the overall demultiplexer performance. A theoretical analysis and simulations show that the exploitation of a two-stage architecture results in a demultiplexing window sharpness and time compression. Eye-diagram and Q-factor experimental characterization at 2.5 Gb/s of the demultiplexer is presented, showing a 25% compression in time of the two-stage switching window and a 4.7 Q-factor improvement.
