On the key role of aluminium and other heteroatoms during interzeolite conversion synthesis (2021)

Interzeolite conversion, a synthesis technique for several zeolite frameworks, has recently yielded a large amount of high-performing catalytic zeolites. Yet, the mechanisms behind the success of interzeolite conversion remain unknown. Conventionally, small oligomers with structural similarity between the parent and daughter zeolites have been proposed, despite the fact these have never been observed experimentally. Moreover, recent synthesis examples contradict the theory that structural similarity between the parent and daughter zeolites enhances interzeolite conversion. In this perspective it is proposed that heteroatoms, such as aluminium, are key players in the processes that determine the successful conversion of the parent zeolite. The role of Al during parent dissolution, and all consecutive stages of crystallization, are discussed by revising a vast body of literature. By better understanding the role of Al during interzeolite conversions, it is possible to elucidate some generic features and to propose some synthetic guidelines for making advantageous catalytic zeolites. The latter analysis was also expanded to the interconversion of zeotype materials where heteroatoms such as tin are present.
2P086 Smart interface antibody design for biosensor(01F. Protein: Engineering,Poster,The 52nd Annual Meeting of the Biophysical Society of Japan(BSJ2014)) (2014)

Biomolecules such as protein, peptide and nucleic acids interact with each other in the cell controlling its life activities. Therefore, techniques to reproduce biomolecular interactions correctly on the solid substrate would be a good versatile way to clarify the biological phenomena. In this research, we investigated the influence of protein orientation and density on peptide-protein interaction (adopting cysteine synthase (CS) complex formation as the model) detection with employing site specific protein immobilization technique. As the results, consideration of the location of functional site with avoiding the steric hindrance by adjusting the protein density and the degree of freedom of the peptide would be important to design higher interaction detection system.

BioMediator data integration: beyond genomics to neuroscience data. (2005)

The BioMediator system developed at the University of Washington (UW) provides a theoretical and practical foundation for data integration across diverse biomedical research domains and various data types. In this paper we demonstrate the generalizability of its architecture through its application to the UW Human Brain Project (HBP) for understanding language organization in the brain. We first describe the system architecture and the characteristics of the four data sources developed by the UW HBP. Second we present the process of developing the application prototype for HBP neuroscience researchers posing queries across these semantically and syntactically heterogeneous neurophysiologic data sources. Then we discuss the benefits and potential limitations of the BioMediator system as a general data integration solution for different user groups in genomic and neuroscience research domains.
Dipyridamole enhances ischaemia-induced arteriogenesis through an endocrine nitrite/nitric oxide-dependent pathway (2010)

Dipyridamole augments nitrite/NO production, leading to enhanced arteriogenesis activity and blood perfusion in ischaemic limbs. Together, these data suggest that dipyridamole can augment ischaemic vessel function and restore blood flow, which may be beneficial in peripheral artery disease.
Sequential Resource Distribution Technique for Multi-User OFDM-SWIPT Based Cooperative Networks (2018)

In this paper, we investigate resource allocation and relay selection in a dual-hop orthogonal frequency division multiplexing (OFDM)-based multi-user network where amplify-and-forward (AF) enabled relays facilitate simultaneous wireless information and power transfer (SWIPT) to the end- users. In this context, we address an optimization problem to maximize the end-users' sum-rate subjected to transmit power and harvested energy constraints. Furthermore, the problem is formulated for both time-switching (TS) and power- splitting (PS) SWIPT schemes.We aim at optimizing the users' SWIPT splitting factors as well as sub-carrier-destination assignment, sub-carrier pairing, and relay-destination coupling metrics. This kind of joint evaluation is combinatorial in nature with non-linear structure involving mixed-integer programming. In this vein, we propose a sub-optimal low complex sequential resource distribution (SRD) method to solve the aforementioned problem. The performance of the proposed SRD technique is compared with a semi- random resource allocation and relay selection approach. Simulation results reveal the benefits of the proposed design under several parameter values with various operating conditions to illustrate the efficiency of SWIPT schemes for the proposed techniques.

A new PWM shoot-through control technique to reduce switching losses in impendance source DC/DC converters (2017)

A simplified shoot-through pulse width modulation (PWM) technique is presented for reducing switching losses in impedance source DC-DC converters. The proposed PWM method alternates shoot-through state conduction in each leg of the H-bridge, thereby increasing controllability of the converter, reducing the number of a switching transients, and reducing the dynamic loss of the converter through soft-switching. The proposed modulation method was verified using a GaN-based quasi-Z-source DC-DC converter. This method demonstrates better performance at low load and with high switching frequency.

Hypothermic preservation of lung allograft inhibits cytokine-induced chemoattractant-1, endothelial leucocyte adhesion molecule, vascular cell adhesion molecule-1 and intracellular adhesion molecule-1 expression (2007)

Organ dysfunction is a major clinical problem after lung transplantation. Prolonged cold ischaemia and reperfusion injury are believed to play a central role in this complication. The influence of cold preservation on subsequent warm reperfusion was studied in an isolated, ventilated and perfused rat lung. Rat lungs were flushed with cold Perfadex-solution and stored at 4 degrees C for different time periods. Thereafter lungs were perfused and ventilated for up to 3 h. Physiological parameters, production of inflammatory mediators and leucocyte infiltration were measured before and after perfusion. Lungs subjected to a cold ischaemia time of up to 6 h showed stable physiological conditions when perfused for 3 h. However, cold-ischaemia time beyond 6 h resulted in profound tissue oedema, thereby impairing ventilation and perfusion. Warm reperfusion and ventilation per se induced a strong inflammatory response, as demonstrated by a significant up-regulation of chemokines and adhesion molecules (cytokine-induced chemoattractant-1, intracellular adhesion molecule and endothelial leucocyte adhesion molecule), accompanied by enhanced leucocyte infiltration. Although the up-regulation of inflammatory mediators was blunted in lungs that were subjected to cold ischaemia, this did not influence leucocyte infiltration. In fact, cold ischaemia time correlated with leucocyte sequestration. Although cold preservation inhibits the expression of inflammatory mediators it does not affect leucocyte sequestration during warm reperfusion. Cold preservation might cause impairment of the endothelial barrier function, as evidenced by tissue oedema and profound leucocyte infiltration.
Microwave noise performance of AlGaN/GaN HEMTs (2000)

The authors have characterised the microwave noise performance of AlGaN/GaN HEMTs epitaxially grown on insulating SiC substrates. The minimum noise figure for 0.25 µm gate-length devices was measured to be 0.77 dB at 5 GHz and 1.06 dB at 10 GHz. The measured minimum noise figures are comparable to those exhibited by GaAs-based FETs, which demonstrates the viability of AlGaN/GaN HEMTs for low-noise applications.
An overview of cryptanalysis research for the advanced encryption standard (2010)

Since its release in November 2001, the Advanced Encryption Standard (NIST FIPS-197) has been the subject of extensive cryptanalysis research. The importance of this research has intensified since AES was named, in 2003, by NSA as a Type-1 Suite B Encryption Algorithm (CNSSP-15). As such, AES is now authorized to protect classified and unclassified national security systems and information. This paper provides an overview of current cryptanalysis research on the AES cryptographic algorithm. Discussion is provided on the impact by each technique to the strength of the algorithm in national security applications. The paper is concluded with an attempt at a forecast of the usable life of AES in these applications.

Dynamic MRM Measurements of Multi-Biomarker Proteins by Triple-Quadrupole Mass Spectrometry with Nanoflow HPLC-Microfluidics Chip (2010)

The development of clinical biomarkers involves discovery, verification, and validation. Recently, multiple reactionmonitoring (MRM) coupled with stable isotope dilution mass spectrometry (IDMS) has shown considerable promise for the directquantification of proteins in clinical samples. In particular, multiple biomarkers have been tracked in a single experiment usingMRM-based MS approaches combined with liquid chromatography. We report here a highly reproducible, quantitative, anddynamic MRM system for validating multi-biomarker proteins using Nanoflow HPLC-Microfluidics Chip/Triple-QuadrupoleMS. In this system, transitions were acquired only during the retention window of each eluting peptide. Transitions with the highestMRM-MS intensities for the five target peptides from colon cancer biomarker candidates were automatically selected usingOptimizer software. Relative to the corresponding non-dynamic system, the dynamic MRM provided significantly improvedcoefficients of variation in experiments with large numbers of transitions. Linear responses were obtained with concentrationsranging from fmol to pmol for five target peptides.

Positioning of High-speed Trains using 5G New Radio Synchronization\n Signals (2018)

We study positioning of high-speed trains in 5G new radio (NR) networks by\nutilizing specific NR synchronization signals. The studies are based on\nsimulations with 3GPP-specified radio channel models including path loss,\nshadowing and fast fading effects. The considered positioning approach exploits\nmeasurement of Time-Of-Arrival (TOA) and Angle-Of-Departure (AOD), which are\nestimated from beamformed NR synchronization signals. Based on the given\nmeasurements and the assumed train movement model, the train position is\ntracked by using an Extended Kalman Filter (EKF), which is able to handle the\nnon-linear relationship between the TOA and AOD measurements, and the estimated\ntrain position parameters. It is shown that in the considered scenario the TOA\nmeasurements are able to achieve better accuracy compared to the AOD\nmeasurements. However, as shown by the results, the best tracking performance\nis achieved, when both of the measurements are considered. In this case, a very\nhigh, sub-meter, tracking accuracy can be achieved for most (&gt;75%) of the\ntracking time, thus achieving the positioning accuracy requirements envisioned\nfor the 5G NR. The pursued high-accuracy and high-availability positioning\ntechnology is considered to be in a key role in several envisioned HST use\ncases, such as mission-critical autonomous train systems.\n
Hybrid RIS-Assisted MIMO Dual-Function Radar-Communication System (2023)

Dual-function radar-communication (DFRC) technology is emerging in next-generation wireless systems. Reconfigurable intelligent surface (RIS) arrays have been suggested as a crucial sensor component of the DFRC. In this paper, we propose a hybrid RIS (HRIS)-assisted multiple-input multiple-output (MIMO) DFRC system, where the HRIS is capable of reflecting communication signals to mobile users and receiving the scattering signal reflected from the radar target simultaneously. Under such a scenario, we are interested in characterizing the fundamental trade-off between radar sensing and communication. Specifically, we study the joint design of the beamforming vectors at the base station (BS) and the parameter configuration of the HRIS so as to maximize the signal-to-interference-and-noise ratio (SINR) of the radar while guaranteeing a communication SINR requirement. To solve the formulated non-convex beamforming design problem, we propose an efficient alternating optimization approach. In particular, for fixed beams at the BS, we use a fast grid search-assisted auto gradient descent (FGS-AGD) algorithm to seek the best HRIS configuration; Then, a closed-form BS beamforming solution is obtained using semidefinite relaxation. Numerical results indicate that compared with benchmark schemes, the proposed approach is capable of improving the radar performance and communication quality significantly and simultaneously.

Grinding Efficiency of an Agitation-Beads Mill. (I). Characteristics of the Particle Size Distribution of the Ground Product. (1991)

Particle size distributions of CaCO3 ground by an agitation-beads mill were analyzed. A horizontal type mill equipped with perforated discs was used. Calcium carbonate was put into the mill with water to give 10% slurry, and the CaCO3 was ground under various conditions. Particle size distribution was approximated by a mono or bimodal-logarithmic normal distribution. Geometric mean and standard deviation of the smaller particle size group were determined only by the energy consumption. The bimodal distribution with the undesired larger particle fraction, FL, appeared when the degree of media filling was small. The fraction FL, depended on the residence time of the specimen but not on energy consumption.

Localised impurity induced layer disordering forlithographic control of the lateral oxidation of AlAs (1997)

The lateral oxidation of AlAs is becoming an important processing tool, but has proven difficult to control. A method is presented to achieve lithographic control of the lateral oxidation process. The technique uses impurity induced layer disordering in buried, heavily Si-doped layers to locally change the oxidation rate of an AlAs layer. Several types of capping conditions during the anneal are discussed.

Sanfte Chemie: Die Synthese von VS2-Nanoröhren (siehe HR-TEM-Bild; Gitterabstand 1.6 nm) aus Oxid-Vorstufen wurde mithilfe eines Chimie-douce-Prozesses durchgeführt. Die Stabilität der VS2-Nanoröhren ist bemerkenswert, zumal VS2 normalerweise nur bei Intercalation durch Alkalimetalle stabil ist. Die Nanoröhren lagern Kupfer reversibel mit hohen Kapazitätswerten ein und könnten Anwendung in Form von Leitern oder Kontakten in elektronischen Schaltkreisen finden.
DAugNet: Unsupervised, Multisource, Multitarget, and Life-Long Domain Adaptation for Semantic Segmentation of Satellite Images (2020)

The domain adaptation of satellite images has recently gained increasing attention to overcome the limited generalization abilities of machine learning models when segmenting large-scale satellite images. Most of the existing approaches seek for adapting the model from one domain to another. However, such single-source and single-target setting prevents the methods from being scalable solutions since, nowadays, multiple sources and target domains having different data distributions are usually available. Besides, the continuous proliferation of satellite images necessitates the classifiers to adapt to continuously increasing data. We propose a novel approach, coined DAugNet, for unsupervised, multisource, multitarget, and life-long domain adaptation of satellite images. It consists of a classifier and a data augmentor. The data augmentor, which is a shallow network, is able to perform style transfer between multiple satellite images in an unsupervised manner, even when new data are added over time. In each training iteration, it provides the classifier with diversified data, which makes the classifier robust to large data distribution difference between the domains. Our extensive experiments prove that DAugNet significantly better generalizes to new geographic locations than the existing approaches.
Lattice-dynamical calculation of the Kapitza resistance between fcc lattices (1989)

The temperature dependence of the Kapitza resistance (thermal boundary resistance) at the interface between two dissimilar solids is calculated for a model system consisting of two semi-infinite, harmonic fcc lattices in register. The spectral density of phonon flux transmitted across the interface is obtained from a numerical calculation of the phonon transmission coefficient and group velocity and is used to calculate the Kapitza resistance. Results for the spectral density of the transmitted phonon flux, the spectral dependence of the phonon transmission coefficient, and the temperature dependence of the thermal boundary resistance are presented. Calculation of the thermal boundary resistance for real systems using the results of this calculation is discussed.
