CaO‐containing La CO 3 OH nanogears and their luminescence and de‐ NO x properties (2018)

Abstract Large‐scale, uniform, monodisperse La CO 3 OH cherry‐blossom‐like nanogears and/or nanocubes have been synthesized under hydrothermal reaction conditions. Upon the addition of only 5 mol% Ca 2+ ions into a La nitrate salts solution with pH 8.5, La CO 3 OH crystals with novel cubic or nanogear structures are formed in the hexagonal phase. The hydrothermal reactions were carried out without the addition of a template or catalysts. Both 24 hour and 48 hour hydrothermal reactions yield 100% pure La CO 3 OH with no irregular particles. We examined the photoluminescence properties of the as‐synthesized powders of the pure La CO 3 OH nanogears and found one broad emission band centered at 394 nm after excitation at λ = 280 nm. The NO reduction activity was also examined over highly dispersed CaO‐containing La 2 O 3 obtained after calcination the La CO 3 OH at 800 ○ C for 2 hours. The CaO‐containing La 2 O 3 catalysts showed good stability for NO reduction with CH 4 in the presence of O 2 and H 2 O vapor.

Combined effects of soy isoflavone and lecithin on bone loss in ovariectomized mice (2021)

The effect of preventing bone loss and osteoclast formation by ingesting soy ISF and LCT at the same time was superior to soy ISF alone as the bioavailability of ISF may have been improved by the emulsification and solvation of LCT. These results suggest the possibility of using the combination of soy ISF and LCT to prevent osteoporosis.
Total Synthesis of Theopederin D (2008)

The transformation is complete! The total synthesis of theopederin D (see structure), a potent cytotoxin, has been achieved through oxidative cleavage of a carbon–carbon bond. Other key transformations include an acid-mediated functionalization of a tetrahydrofuranol, a syn-selective glycal epoxide ring-opening, and an asymmetric aldehyde/acid chloride condensation.

Adsorption and Pressure Swing Desorption of NOx in Na−Y Zeolite:  Experiments and Modeling (2002)

Pressure swing NOx adsorption-desorption cycles were performed in the temperature range 200-350 degrees C using a fixed adsorbent bed of compressed Na-Y pellets and using a honeycomb coated with Na-Y powder. The experiments were performed using a synthetic gas mixture mimicking exhaust from a lean burn internal combustion engine. Na-Y zeolite coadsorbs NO and NO2 as N2O3, which in the regeneration were displaced by competitively adsorbed water molecules from a hydrated air stream. The performance of the fixed bed in these NOx adsorption and displacement desorption processes were modeled with a one-dimensional model. The kinetic and thermodynamic parameters from the fixed bed model were implemented in a model for the operation of the monolith. The experimental adsorption and desorption NOx concentration profiles in the monolith were reasonably well reproduced by the model. The water content of the flushing stream and the stripping gas flow rate are key process parameters. Technically, both parameters can be optimized in a valveless system with rotating honeycomb adsorbent comprising a NOx adsorption, a water injection and a NOx evacuation section.
High Performance Speed Control Based on Instantaneous Speed Observer Considering the Characteristics of DC Chopper in Low Speed Range (1997)

This paper proposes a new high performance speed control method for wide speed range, which is based on instantaneous speed observer considering the characteristics of DC chopper. In order to regulate a motor speed for wide speed reference including a very low speed range, this paper designs the instantaneous speed observer which uses the information of an armature current and an armature voltage. This observer has no effect of inertia variation and disturbance torque completely, but it has the effect of electrical parameter variation. Hence, this paper proposes a new identification algorithm to cancel out the estimation error caused by both the resistance variation and the voltage drop. The proposed observer can always estimate an instantaneous value of motor speed. The proposed total system becomes a new robust speed servo system for a wide speed range.
Market research on garment-based "wearables" and biophysical monitoring and a new monitoring method. (2004)

Technology advancements are foremost on the minds of scientists and developers who are working to overcome the many hurdles associated with bringing consumers the enhanced benefits associated with next generation wearable health systems. Often the technology work takes a front seat to the basic requirements of traditional consumer apparel. The choices of what consumers elect to place and carry on their body can be practical, logical, emotional and sometimes seemingly random. By providing insights and data to support the claims, developers of wearable health systems of the future will be able improve their chance of consumer adoption and continued use by gaining a clearer picture of the people that will be wearing the systems. Results from 5 different consumer research studies are presented, examining consumer buying patterns, gender differences, regional differences, their receptivity to health benefits delivered via clothing and what they want from technology enhanced clothing. Market research related to biophysical monitoring utilizing smart fabrics or interactive textiles show a critical level of commercial activity. Medical applications focused on the aged, infant and critical patient care are taking the lead. This paper presents a look at the biophysical monitoring market and discusses new materials useful in garment systems and the challenges remaining for their development and integration with textiles. A new method of non-invasive monitoring of periodic activity is discussed.
New Vanadium Tris(tert-butoxy)siloxy Complexes and Their Thermolytic Conversions to Vanadia−Silica Materials (2002)

The V(IV) alkoxysiloxy complexes (tBuO)3VOSi(OtBu)3 (1) and (tBuO)2V[OSi(OtBu)3]2 (2) were synthesized via the silanolysis of V(OtBu)4 with 1 and 2 equiv of HOSi(OtBu)3, respectively. Complexes 1 and 2 are efficient single-source molecular precursors to homogeneous V/Si/O materials via the thermolytic molecular precursor method. The thermal transformations of these complexes occurred at low temperatures (≤160 °C), via the elimination of isobutene as the major carbon-containing product. Thermolyses of 1 in the solid state and in solution (forming a xerogel in the latter case) yielded V/Si/O materials (VOSi1ss and VOSi1xg, respectively) with low surface areas (30−40 m2 g-1). After calcination at 400 °C in O2, these materials exhibited powder X-ray diffraction (PXRD) patterns consistent with the presence of V2O5. Similar thermolyses of 2 yielded V/Si/O materials (VOSi2ss and VOSi2xg) that exhibited higher surface areas (up to 170 and 70 m2 g-1, respectively) and V2O5 crystallite formation after calcination at 400 °C. Comparisons of VOSi1xg and VOSi2xg with a previously reported V/Si/O xerogel (VOSi3xg), generated from the V(V) precursor OV[OSi(OtBu)3]3, revealed interesting differences. Crystalline V2O5 was first observed in VOSi3xg after calcination at only 300 °C in O2. Transmission electron microscopy (TEM) and PXRD were used to determine that the average size of the V2O5 crystallites in the V/Si/O xerogels, after calcination at a given temperature, increased with increasing silicon content of the precursor and was highest for the V(V) tris(siloxide). The precursors containing vanadium in the lower oxidation state (IV) appear to initially provide more homogeneous V/Si/O materials. Higher Si content for the precursor leads to a greater surface area for the resultant material, but also to earlier phase separation during the calcination process.
Guanine-specific binding at an intercalated DNA junction (2000)

Some DNA-intercalating tricyclic carboxamides have the unusual ability [1] to poison both topoisomerase I and topoisomerase II [2], the structurally diverse enzymes that generate transient single or double strand breaks in the DNA phosphodiester backbone to allow the passage of one or two DNA strands during replication [3]. The crystal structure of an acridine-4-carboxamide with the DNA sequence CG(5BrU)ACG reveals a novel quadruplex-like intercalation cavity. The drug/DNA complex was crystallised in the presence of Co 2+ ions, and was solved by MAD phasing at 2.0 and refined with SHELXL to R 19.5%.
[Triumphal march of cancer therapy goes on]. (2015)

Therapeutic results for cancer have gradually improved. The relative five-year survival rate of those affected with the disease already exceeds 65% in Finland. New cancer therapies play an indisputable role in the improvement of the prognosis. Besides therapy and its availability, many other causes may also have a considerable effect on the survival of affected persons, making comparison of regional survival rates unreliable as a measure of cancer treatment. The review deals with factors affecting the survival of persons having cancer and includes descriptions of some of the most recent cancer treatments and a discussion about the challenges of developing cancer therapies.
Vertically oriented metamaterial broadband linear polariser (2018)

Control and manipulation of polarisation is an important topic for imaging and light matter interactions. In the infrared regime, the large wavelengths make wire grid polarisers (WGPs) a viable option, as it is possible to create periodic arrays of metallic wires at that scale. The recent advent of metamaterials has spurred an increase in non‐traditional polariser motifs centred around more complicated repeat units, which potentially provide more functionality. The authors explore the use of 2D arrays of single and back‐to‐back vertically oriented cross dipoles arranged in a cubic in‐plane silicon matrix. They show that both single and back‐to‐back versions have higher rejection ratios and larger bandwidths than either WGPs or 2D arrays of linear dipoles.

WikiGraphs: A Wikipedia Text - Knowledge Graph Paired Dataset (2021)

We present a new dataset of Wikipedia articles each paired with a knowledge graph, to facilitate the research in conditional text generation, graph generation and graph representation learning.Existing graph-text paired datasets typically contain small graphs and short text (1 or few sentences), thus limiting the capabilities of the models that can be learned on the data.Our new dataset WikiGraphs is collected by pairing each Wikipedia article from the established WikiText-103 benchmark (Merity et al., 2016) with a subgraph from the Freebase knowledge graph (Bollacker et al., 2008).This makes it easy to benchmark against other state-of-the-art text generative models that are capable of generating long paragraphs of coherent text.Both the graphs and the text data are of significantly larger scale compared to prior graph-text paired datasets.We present baseline graph neural network and transformer model results on our dataset for 3 tasks: graph → text generation, graph → text retrieval and text → graph retrieval.We show that better conditioning on the graph provides gains in generation and retrieval quality but there is still large room for improvement.
A nonparametric learning approach to vision based mobile robot localization (2002)

A nonparametric learning algorithm is used to build a robust mapping between an image obtained from a mobile robot's on-board camera, and the robot's current position. The mapping uses 19,200 unprocessed pixel values (160 by 120 pixel image). Because the learning algorithm is nonparametric, it uses the learning data obtained from these raw pixel values to automatically choose a structure for the mapping without human intervention, or any a priori assumptions about what type of image features should be used. The learning data consisting of a series example image inputs and corresponding position values, is collected in a calibration phase where the robot randomly traverses its intended workspace. This process of building visual localization maps for mobile robots is completely general and can be applied to any implementation which uses on-board cameras. We demonstrate the feasibility of this approach on a mobile platform performing in a robotics laboratory workspace. This workspace is visually cluttered, with humans and other objects continually moving within the robot's environment. The mapping learned in this environment is robust to these dynamic visual features and consistently reports timely localization information (at greater than 7 Hz) to within acceptable limits.
Peer-to-peer based energy trading system for heterogeneous small-scale DERs (2017)

In the near future, Peer-to-Peer (P2P) energy trading is expected to contribute potentially in expanding popularity of small-scale Distributed Energy Resources (DERs). This will arguably create new markets (a new business model). Storing energy for future use is still considered to be an expensive solution. Therefore, establishing a cooperative network among the energy producers and consumers would lead to maximize energy utilization, and this in turn will contribute in reducing unit energy cost and carbon footprint. In this paper, to gain enormous potential of P2P energy trading, we come up with functional requirements and service scenarios for designing and implementing a P2P energy trading system that facilitates coordination among energy producers (DERs) and consumers. Additionally, to actualize this energy trading system, we implement an energy information and communication standard model, allowing energy trading information sharing among the energy producers and consumers.
A Role for the C Terminus of Mopeia Virus Nucleoprotein in Its Incorporation into Z Protein-Induced Virus-Like Particles (2010)

Arenaviruses are enveloped, negative-strand RNA viruses. For several arenaviruses, virus-like particle (VLP) formation requires the viral matrix Z protein. However, the mechanism by which viral ribonucleoprotein complexes are incorporated into virions is poorly understood. Here, we show that the expression of the Z protein and nucleoprotein (NP) of Mopeia virus, a close relative of the pathogenic Lassa virus, resulted in the highly selective incorporation of the NP protein into Z protein-induced VLPs. Moreover, the Z protein promoted the association of NP with cellular membranes, suggesting that the association of NP, Z, and the cellular membranes may facilitate the efficient incorporation of NP into VLPs. By employing a series of NP deletion constructs and testing their VLP incorporation, we further demonstrated an important role for the C-terminal half of NP in its incorporation into VLPs.

Question-Answering for Agricultural Open Data. (2014)

In the agricultural sector, the improvement of productivity and quality with respect to such attributes as safety, security and taste has been required in recent years. We aim to contribute to such improvement through the application of Information and Communication Technology (ICT). In this paper, we first propose a model of agricultural knowledge by Linked Open Data (LOD) with a view to establishing an open standard for agricultural data, allowing flexible schemas based on ontology alignment. We also present a semi-automatic mechanism that we developed to extract agricultural knowledge from the Web, which involves a bootstrapping method and dependency parsing, and confirmed a certain degree of accuracy. Moreover, we present a voice-controlled question-answering system that we developed for the LOD using triplification of query sentences and graph pattern matching of the triples. Finally, we confirm through a use case that users can obtain the necessary knowledge for several problems encountered in the agricultural workplace.
Time-Resolved Measurements Using Stroboscopic Excitation (2005)

The future of high efficiency, multi-junction space solar cells (2008)

Space power generation has involved the continual improvement of device designs to achieve higher efficiencies. The improvements have involved both evolutionary as well as revolutionary changes in device design. Currently, the lattice matched, GaInP <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> /GaAs/Ge multi-junction solar cell is the device of choice for space power generation. The current design of this architecture has reached the 30% efficiency level, the expected maximum performance level for this architecture in a manufacturing environment. However, the band gaps for the GaInP <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> /GaAs/Ge device are not the ideal set of three junctions for maximum power conversion. We present theoretical modeling for 3-, 4-, 5-, and 6-junction devices. Other criteria for space power generation, including reliability, weight, and cost are discussed. Different approaches to higher efficiencies are discussed and are evaluated not only in the light of power conversion efficiency, but also in light of the other criteria.
Discovery of 18F-JK-PSMA-7, a PET Probe for the Detection of Small PSMA-Positive Lesions (2018)

Prostate-specific membrane antigen (PSMA), expressed by most prostate carcinomas (PCa), is a promising target for PCa imaging. The application of PSMA-specific <sup>18</sup>F-labeled PET probes such as <sup>18</sup>F-DCFPyL and <sup>18</sup>F-PSMA-1007 considerably improved the accuracy of PCa tumor detection. However, there remains a need for further improvements in sensitivity and specificity. The aim of this study was the development of highly selective and specific PSMA probes with enhanced imaging properties, in comparison with <sup>18</sup>F-DCFPyL, <sup>18</sup>F-PSMA-1007, and <sup>68</sup>Ga-PSMA-11. <b>Methods:</b> Eight novel <sup>18</sup>F-labeled PSMA ligands were prepared. Their cellular uptake in PSMA-positive LNCaP C4-2 and PSMA-negative PC-3 cells was compared with that of <sup>18</sup>F-DCFPyL. The most promising candidates were additionally evaluated by small-animal PET in healthy rats using PSMA-positive peripheral ganglia as a model for small PCa lesions. PET images of the ligand with the best outcome, <sup>18</sup>F-JK-PSMA-7, were compared with those of <sup>18</sup>F-DCFPyL, <sup>18</sup>F-PSMA-1007, and <sup>68</sup>Ga-PSMA-11 with respect to key image-quality parameters for the time frame 60-120 min. <b>Results:</b> Compared with <sup>18</sup>F-DCFPyL, <sup>18</sup>F-JK-PSMA-7 demonstrated increased PSMA-specific cellular uptake. Although target-to-background ratios of <sup>18</sup>F-DCFPyL and <sup>18</sup>F-PSMA-1007 were comparable, this parameter was higher for <sup>18</sup>F-JK-PSMA-7 and lower for <sup>68</sup>Ga-PSMA-11. Image acutance was significantly higher for <sup>18</sup>F-JK-PSMA-7 and <sup>18</sup>F-PSMA-1007 than for <sup>18</sup>F-DCFPyL and <sup>68</sup>Ga-PSMA-11. Image resolution was similar for all 4 tracers. <sup>18</sup>F-PSMA-1007 demonstrated significantly higher blood protein binding and bone uptake than the other tracers. <b>Conclusion:</b><sup>18</sup>F-JK-PSMA-7 is a promising candidate for high-quality visualization of small PSMA-positive lesions. Excellent preclinical imaging properties justify further preclinical and clinical studies of this tracer.
Self-Learning Detector for the Cell-Free Massive MIMO Uplink: The Line-of-Sight Case (2020)

The precoding in cell-free massive multiple-input multiple-output (MIMO) technology relies on accurate knowledge of channel responses between users (UEs) and access points (APs). Obtaining high-quality channel estimates in turn requires the path losses between pairs of UEs and APs to be known. These path losses may change rapidly especially in line-of-sight environments with moving blocking objects. A difficulty in the estimation of path losses is pilot contamination, that is, simultaneously transmitted pilots from different UEs that may add up destructively or constructively by chance, seriously affecting the estimation quality (and hence the eventual performance). A method for estimation of path losses, along with an accompanying pilot transmission scheme, is proposed that works for both Rayleigh fading and line-of-sight channels and that significantly improves performance over baseline state-of-the-art. The salient feature of the pilot transmission scheme is that pilots are structurally phase-rotated over different coherence blocks (according to a pre-determined function known to all parties), in order to create an effective statistical distribution of the received pilot signal that can be efficiently exploited by the proposed estimation algorithm.
