Enhanced photo-catalytic activity of ordered mesoporous indium oxide nanocrystals in the conversion of CO<sub>2</sub>into methanol (2017)

Ordered mesoporous indium oxide nanocrystal (m-In<sub>2</sub>O<sub>3</sub>) was synthesized by nanocasting technique, in which highly ordered mesoporous silca (SBA-15) was used as structural matrix. X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halanda (BJH) studies were carried out on m-In<sub>2</sub>O<sub>3</sub> and the results revealed that this material has a highly ordered mesoporous surface with reduced grain size, increased surface area and surface volume compared to the non porous indium oxide. The diffuse reluctance spectrum exhibited substantially improved light absorption efficiency in m-In<sub>2</sub>O<sub>3</sub> compared to normal indium oxide, however, no considerable change in the band gap energies of these materials was observed. When m-In<sub>2</sub>O<sub>3</sub> was used as a photo-catalyst in the photo-catalytic process of converting carbon dioxide (CO<sub>2</sub>) into methanol under the pulsed laser radiation of 266-nm wavelengths, an enhanced photo-catalytic activity with the quantum efficiency of 4.5% and conversion efficiency of 46.3% were observed. It was found that the methanol production yield in this chemical process is as high as 485 µlg<sup>-1</sup> h<sup>-1</sup> after 150 min of irradiation, which is substantially higher than the yields reported in the literature. It is quite clear from the results that the introduction of mesoporosity in indium oxide, and the consequent enhancement of positive attributes required for a photo-catalyst, transformed photo-catalytically weak indium oxide into an effective photo-catalyst for the conversion of CO<sub>2</sub> into methanol.
Mid‐height seismic isolation of equipment in nuclear power plants (2023)

Abstract An innovative seismic isolation solution for designers of safety‐class equipment in advanced nuclear power plants is introduced. The test specimen was a tall, slender, carbon steel vessel that could represent a reactor vessel, steam generator, or a heat exchanger in a nuclear power plant: 240 inches tall, outer diameter of 60 inches, and wall thickness of 1 inch. The vessel was supported by three radial mounts at its mid‐height, near its center of gravity, on a steel frame. The vessel was subjected to three‐component ground motions using a 6DOF earthquake simulator. The specimen was filled with water for testing to indirectly account for the fluid and internal equipment present inside a prototype vessel. Three configurations were tested: non‐isolated, isolated using single Friction Pendulum (SFP) bearings, and isolated using triple Friction Pendulum (TFP) bearings. The test results demonstrate that mid‐height seismic isolation is practical and enables a significant reduction in horizontal spectral accelerations. These outcomes are not specific to the spherical sliding bearings used in the experiments but are broadly applicable to mid‐height, seismically isolated equipment.
Synthesis of des-<i>A</i>-<i>B</i>-secocholestanes (1984)

Two independent synthetic routes to 10-oxo-5, 10-seco-des-A-cholestan-5-oic acid (5) are described. The route including the Baeyer–Villiger rearrangement of (10R)-des-A-cholestan-5-one (2a), followed by hydrolysis of the lactone 3a obtained and oxidation of the C-10 hydroxyl group, seems to be superior to ozonolysis of the 5(10)-enol acetate 6 of des-A-ketone which resulted in the formation of 5,10-seco-des-A-19-norcholestan-5,10-dioic acid (7), in addition to the compound 5. Product 7 and its 6-nor analog 12 have also been obtained by ruthenium tetroxide oxidation of the respective A-ring phenols 8, 9, and 11.
Abstract 2514: Automatic Biventricular Capture Verification Based On Morphological Analysis of the Intracadiac Electrogram Signal (2007)

Objective: We test a new biventricular capture verification algorithm, which can be used to adjust the pacing output in right ventricle (RV) and left ventricle (LV), to ensure the safety and efficacy of the cardiac resynchronization therapy (CRT). Methods: The algorithm calculates a novel index called ASCI, which measures the morphological similarity between the intracardiac electrogram (IEGM) signal and a template waveform representing captured paces. Ventricular capture (CAP) is verified if ASCI is greater than a predefined threshold, whereas non-capture (NC) is declared otherwise. CRT pacemakers were implanted in 6 dogs. During a mean follow-up of 23 days, 175 biventricular threshold tests were conducted by running a customized program, with various combinations of pace/sense polarities. Wideband RV and LV IEGM were recorded and downloaded for off-line analysis by the algorithm. Template signals for each pace/sense configuration in each chamber were created from the average of 4 captured beats. Each pace was annotated for CAP or NC by visual examination of the IEGM and based on stored data log of the pacing parameters. Results: A total of 9991 CAP paces (5104 RV, 4887 LV) and 4474 NC paces (2136 RV, 2338 LV) were eligible for morphology analysis. In both RV and LV, the calculated ASCIs were well separated for CAP and NC paces (Figure ): 0.83 ± 0.12 (RV CAP), 0.85 ± 0.11 (LV CAP), -0.06 ± 0.13 (RV NC), -0.07 ± 0.14 (LV NC). The classification accuracy of the algorithm remained &gt;= 99% for any ASCI threshold value choosing between 0.18 and 0.52. Conclusion: This study demonstrated the feasibility to perform automatic biventricular capture verification based on morphology analysis of the IEGM.
Solvent effects on the vibrational frequency of I2− in size-selected I2−(Ar)n and I2−(CO2)n clusters (1998)

The vibrational frequency of the I2− chromophore in size-selected I2−(Ar)n and I2−(CO2)n clusters has been measured to wave-number accuracy. The frequencies are determined by creating a coherent superposition of vibrational levels with a femtosecond laser pulse via a resonance impulsive stimulated Raman scattering process. The resulting wave-packet oscillations are detected with femtosecond photoelectron spectroscopy. Blueshifting of the frequency occurs upon solvation, with larger shifts observed for solvation with CO2. The nature of the shifting is discussed and related to specific cluster geometries.

Conclusion (2014)

The previous chapters in this book demonstrate how collaborative research linked to DHS Centers for Excellence support the overall mission of DHS, while at the same time support research by faculty and students at institutions of higher education. The value added and success of these programs highlight the importance of developing effective partnerships that can lead to quality research experiences for faculty, students, and teachers. In addition, the research highlighted stresses the importance of developing a strong workforce that begins long before students make the transition to institutions of higher learning. It is important that early career faculty researchers, experienced researchers, as well as undergraduate and graduate students understand DHS research priority areas that can effectively support the overall mission of DHS. The collaborative research that is linked to other federal and state agencies is important in addressing complex security issues that have an impact on the general public.
A Case Report of Intracortical Hemangioma A Forgotten Intracortical Lesion (1994)

The differential diagnosis for lytic intracortical lesions consists primarily of osteoid osteoma and Brodie's abscess. A third, less-well-known lesion is the intracortical hemangioma. It has an identical appearance to the two aforementioned lesions on bone scan and radiographs. This case report will describe the magnetic resonance imaging appearance of intracortical hemangioma and how it might be differentiated from osteoid osteoma and Brodie's abscess.
Glucosinolate Biosynthesis (Further Characterization of the Aldoxime-Forming Microsomal Monooxygenases in Oilseed Rape Leaves) (1995)

The initial steps in glucosinolate biosynthesis are thought to proceed from amino acids, via N-hydroxy amino acids, to aldoximes. We showed previously that microsomes from green leaves of oilseed rape (Brassica napus cv Bienvenu) contain two distinct monooxygenases that catalyze the conversion of homophenylalanine and dihomomethionine to their respective aldoximes. Further characterization of these enzymes has now demonstrated that the latter enzyme catalyzes the NADPH-dependent oxidative decarboxylation of two higher homologs of methionine, in addition to dihomomethionine. No activity was found for either enzyme with L-methionine, DL-homomethionine, L-phenylalanine, L-tyrosine, or L-tryptophan. Both of these rape monooxygenase activities are dependent on O2, not requiring any other O2 species or radical. The presence of an unoxidized sulfur atom and its relative position in the side chain of the aliphatic substrates are important for binding to the active site of the methionine-homolog enzyme. Neither enzyme has any characteristics of a cytochrome P450-type enzyme, and antiserum raised against cytochrome P450 reductase did not significantly inhibit monooxygenase activity.
P4‐297: Imaging amyloid plaque deposition with [18F]‐AV‐45 in living APP/PS1‐21 mice (2011)

Alzheimer's disease, the most common age-related neurodegenerative disorder, is characterized by the invariant cerebral accumulation of ß-amyloid peptide. In humans, [18F]-AV-45-PET is currently studied to follow-up in vivo amyloid accumulation. Here, [18F]-AV-45 was used to visualize and follow-up amyloid deposition in a transgenic mouse model of amyloidosis (APP/PS1-21), ex vivo by autoradiography and in vivo by microPET. [18F]-AV-45 was produced in a fully automated procedure suitable for routine clinical application. Ex vivo autoradiography was conducted in 3, 8 and 12 month-old APP/PS1-21 and age-matched C57Bl6 mice as controls. Under anesthesia, the mice were injected with [18F]-AV-45 and euthanatized 30 min after injection. Frozen brain tissue was then coronally cut into 20 μm-thick sections, exposed to imaging plate and scanned with a phosphor-imager. The intensity of radioactive signals was measured in cortex, hippocampus, striatum and cerebellum (control region). Longitudinal PET studies were performed at 3, 5, 8 and 12 months in APP/PS1-21 and C57Bl6 mice. PET images were recorded on a high-resolution small-animal PET imaging device and co-registered with T2-weighted magnetic resonance images (MRI) to ensure proper ROI placement (region of interest). Thioflavin-S staining was performed on APP/PS1-21 and C57Bl6 brain sections. Autoradiograms of the brain sections highlighted an increase of [18F]-AV-45 uptake in APP/PS1 mice compared to age-matched controls (3 months: +23%, 8 months: +53%, 12 months: +29%). At 8 months, an intense labeling (compared to age-matched control animals) was observed in the cortical regions (+ 72%), hippocampus (+ 47%) and striatum (+ 42%). This intense accumulation of radiotracer was found in close association with thioflavin S-positive-amyloid plaques. PET study confirmed the increased [18F]-AV-45 uptake in APP/PS1 mice compared to control animals and demonstrated that tracer uptake increased in tight association with age and amyloid plaques revealed by thioflavin S. This longitudinal assessment demonstrated the ability of [18F]-AV-45-microPET to visualize and quantitatively measure progressive amyloid accumulation in living APP/PS1 mice.

Efficient Control Flow in Dataflow Systems: When Ease-of-Use Meets High Performance (2021)

Modern data analysis tasks often involve control flow statements, such as iterations. Common examples are PageRank and K-means. To achieve scalability, developers usually implement data analysis tasks in distributed dataflow systems, such as Spark and Flink. However, for tasks with control flow statements, these systems still either suffer from poor performance or are hard to use. For example, while Flink supports iterations and Spark provides ease-of-use, Flink is hard to use and Spark has poor performance for iterative tasks. As a result, developers typically have to implement different workarounds to run their jobs with control flow statements in an easy and efficient way.We propose Mitos, a system that achieves the best of both worlds: it achieves both high performance and ease-of-use. Mitos uses an intermediate representation that abstracts away specific control flow statements and is able to represent any imperative control flow. This facilitates building the dataflow graph and coordinating the distributed execution of control flow in a way that is not tied to specific control flow constructs. Our experimental evaluation shows that the performance of Mitos is more than one order of magnitude better than systems that launch new dataflow jobs for every iteration step. Remarkably, it is also up to 10.5 times faster than Flink, which has native iteration support, while matching the ease-of-use of Spark.
Photopolymers Based on Boronic Esters for the Enhanced Degradation of 3D-Printed Scaffolds (2023)

Lithography-based additive manufacturing technologies have become a valuable tool in tissue engineering for the fabrication of biocompatible and biodegradable bone regeneration scaffolds. Currently employed photopolymers based on (meth)acrylates, vinyl esters, or vinyl carbonates display undesirable properties such as irritancy or cytotoxicity of residual monomers, degradation via autocatalytic bulk erosion leading to implant failure, or insufficient degradation speed in vivo. This work investigates monomers containing boronic ester bonds as a potential alternative to these state-of-the-art compounds. Next to a facile synthesis, significantly lower cytotoxicity was shown for this generation of biocompatible allyl ether monomers compared to commonly utilized (meth)acrylates. Photopolymerization via the thiol–ene reaction showed that rigid boronic esters led to sufficient photoreactivity for 3D structuring, and materials with reduced shrinkage and excellent mechanical properties can be obtained. Additionally, degradation studies revealed significantly accelerated degradation via the desired surface erosion under physiological and acidic conditions. Ultimately, a 3D test structure out of a boronic ester-based formulation was successfully stereolithography-printed, showing the great potential of these monomers as precursors for photopolymers used for 3D-printed implants with improved degradation behavior without forfeiting good mechanical properties.

Synchronization Detection of Multicamera System Based on LED Matrix (2016)

In a nonsynchronous multicamera system, cameras start to capture pictures at different time. To synchronize cameras, we should know the capture time of each camera and adjust them according to the time. We propose a high precision method to detect the synchronization accuracy by using a FPGA based LED matrix as a detector. The LEDs in the matrix are encoded basing on the carry-flowing encoding (CFE) method, so the matrix displays a sequence of different LEDs combination states. When the cameras capture an image of the detector, the state of LED matrix in the image and the capture time that it represents can be determined. According to the capture time, we can detect the relative time interval between cameras, adjust them on account of the interval, and finally synchronize all the cameras. A four-camera synchronization system is setup to verify this method. Experiment results show that the detection of the synchronization accuracy can be less than 1ms. The proposed multicamera detection method is simple and easy to use, it can be applied to most of the multicamera systems.
Nd:YAG laser-assisted angioplasty in femoropopliteal artery occlusions: "hot" versus "cold" recanalization with transparent contact probe. (1992)

Percutaneous recanalization of femoropopliteal artery occlusions (1-21 cm; median, 8 cm) was attempted in 50 patients. A 2.2-mm-diameter contact probe catheter connected to a continuous-wave neodymium yttrium aluminum garnet (Nd:YAG) laser was used. The laser was activated (15 W, 1-second pulses) only if too much resistance was met. Balloon angioplasty was performed after successful traversal of the occlusion. Primary success was achieved in 40 of 50 patients (80%). In 20 cases, recanalization was achieved mechanically (cold group). In the other 20 cases, recanalization was achieved with the help of laser irradiation (hot group: 15-405 J; median, 90 J). Except for the length of the obstruction (longer in the cold group), the two groups did not differ in baseline characteristics. Neither the length of the occlusion nor the duration of symptoms correlated with failure or success or with the delivered laser energy. Cold and hot groups did not differ with regard to functional improvement and angiographic patency at 3 and 12 months (94% +/- 4). Thus, brief laser activation doubled the cold primary success rate, but the major action of the laser contact probe is mechanical remodeling of the obstruction.
A Radio Frequency Fingerprint Identification Method for Wireless Devices Based on ShuffleNet-SVM (2022)

Radio frequency fingerprint identification can be used for device authentication, network access management, malicious device tracing, and identity spoofing attacks. The feature representation and pattern recognition capabilities of deep learning algorithms are of great significance for improving the identification capability of radio frequency fingerprint-based wireless devices. Aiming at the problem of radio frequency fingerprint identification of wireless devices, this paper proposes a radio frequency fingerprint identification method for wireless devices based on ShuffleNet-SVM. Firstly, the original signal of the wireless device is processed by the constant Q transform. Secondly, the obtained CQT spectrum is input into the ShuffleNet model for training to achieve adaptive feature extraction, and then the output of the convolution layer is extracted as the RF fingerprint feature vector, which is used as the input of the support vector machine. Finally, the output of the identification result can realize the radio frequency fingerprint identification of the wireless device. Based on the Bluetooth device data set, a series of experiments verify that the proposed method is superior to the comparison models and other time-frequency processing methods in terms of accuracy and robustness.
The Essential Root Oil of Peucedanum lancifolium Lange and Chemotaxonomic Implications (1989)

Abstract The composition of the essential root oil of Peucedanum lancifolium Lange (A piaceae), growing in the Atlantic coast regions of France, North-West Spain und Portugal was investigated by chromatographic and spectroscopic methods. Forty five terpenoids, many of them of already known structure, and several aliphatic esters have been identified. Besides the main constituent, the irregular sesquiterpene alcohol trans-sesquilavandulol, representing 53.37% of the total oil, some hitherto unknown sesquiterpenoids with an irregular carbon skeleton were found. The possible chemotaxonomic value of the essential oil com position with regard to the close botanical relationship of Peucedanum lancifolium Lange and Peucedanum palustre (L .) M oench is briefly discussed. With the exception of these two species, trans-sesquilavandulol was not found in any other member of the genus Peucedanum.
NBRP databases: databases of biological resources in Japan (2009)

The National BioResource Project (NBRP) is a Japanese project that aims to establish a system for collecting, preserving and providing bioresources for use as experimental materials for life science research. It is promoted by 27 core resource facilities, each concerned with a particular group of organisms, and by one information center. The NBRP database is a product of this project. Thirty databases and an integrated database-retrieval system (BioResource World: BRW) have been created and made available through the NBRP home page (http://www.nbrp.jp). The 30 independent databases have individual features which directly reflect the data maintained by each resource facility. The BRW is designed for users who need to search across several resources without moving from one database to another. BRW provides access to a collection of 4.5-million records on bioresources including wild species, inbred lines, mutants, genetically engineered lines, DNA clones and so on. BRW supports summary browsing, keyword searching, and searching by DNA sequences or gene ontology. The results of searches provide links to online requests for distribution of research materials. A circulation system allows users to submit details of papers published on research conducted using NBRP resources.
The application of calcined natural dolomitic rock as a solid base catalyst in triglyceride transesterification for biodiesel synthesis (2008)

Natural dolomitic rock has been investigated in the transesterification of C4 and C8 triglycerides and olive oil with a view to determining its viability as a solid base catalyst for use in biodiesel synthesis. XRD reveals that the dolomitic rock comprised 77% dolomite and 23% magnesian calcite. The generation of basic sites requires calcination at 900 °C, which increases the surface area and transforms the mineral into MgO nanocrystallites dispersed over CaO particles. Calcined dolomitic rock exhibits high activity towards the liquid phase transesterification of glyceryl tributyrate and trioctanoate, and even olive oil, with methanol for biodiesel production.
Dilated Matrix Inequalities for Control Design in Systems with Actuator Constraint (2013)

In this paper, we present a new variation of dilated matrix inequalities (MIs) for Bounded Real MI, invariant set MI and constraint MI, for both state and output feedback synthesis problems. In these dilated MIs, system matrices are separated from Lyapunov matrices to allow the use of different Lyapunov matrices in multi-objective and robust problems. To demonstrate the benefit of these new dilated MIs over conventional ones, they are used in solving controller synthesis problem for systems with bounded actuator in disturbance attenuation. It is shown that for the resulting multi-objective saturation problem, the new form of dilated MIs achieves an upper bound for $L_2$ gain that is less than or equal to the upper bound estimate achieved by conventional method.
