Finding Vulnerable Atherosclerotic Plaques (2004)

Techniques to identify and treat vulnerable plaques are the focus of enormous research. Some have questioned the benefit of locating individual vulnerable plaque in a multifocal disease. On autopsy, it is found that most deaths are caused by thrombotic occlusion of a single plaque; simultaneous occurrence of 2 occlusive thrombi is rare, but a second vulnerable plaque is common, particularly in acute myocardial infarction (MI). Angiographic progression is poorly predicted by risk factors, and angiographic progression is a weak predictor of MI or death. Intravascular ultrasonography (intravascular ultrasound [IVUS]) studies find plaque rupture in most MI patients and in approximately half with unstable angina, but in only a minority of patients with stable angina. IVUS identifies a second vulnerable plaque in many patients with unstable angina, and in most MI patients. Angioscopy reveals a very low incidence of a second vulnerable plaque compared with angiography and IVUS, but identifies additional yellow plaques in many patients with stable angina and in most patients with unstable angina or MI. Using thermography catheters and a temperature cutoff of 0.1 degrees C, approximately half the patients with stable angina have >1 hot lesion; however, if the cutoff is 0.2 degrees C, only approximately 15% have a second hot lesion. New imaging techniques may detect additional characteristics of plaques and new predictive models may assess the risk of vulnerable plaques and patients. This approach enables physicians to "buy time" by application of local therapies until systemic therapies stabilize plaques. This may also reduce the risk in subjects in whom systemic therapies do not work.
II. URANIUM DICARBIDE, URANIUM METAL-MONOCARBIDE MIXTURES AND URANIUM MONOCARBIDE-DICARBIDE MIXTURES* (1963)

Reactions with water of as-cast uranium carbides with total-C/U atom ratios varying from 0.4 to 2.2 were investigated using gas-chromatography for analysis of the gaseous products. Uranium metal-uranium monocarbide mixtures yielded 2 moles of free hydrogen per mole of fr~e metal, methane, small quantities of higher molecular weight gaseous hydrocarbons, and a hydrous, uranium (IV) oxide. The gaseous products contained all the carbon originally present in the mixtures. Uranium dicarbide (UC1.85 ± 0.03) yielded a mixture of 36 hydrocarbons (average composition: methane, 15 vol. %; ethane, 28%; C i - to C 8 -alkanes, 7%; alkenes, 8%; alkynes, 0.6%; and unidentified unsa~urates, 1%), free hydrogen (40 vol. %), a water-insoluble wax, and a hydrous, uranium (IV) oxide. Forty per cent of the combined carbon was found in the gas and 25% in the wax. Varying the reaction temperature between 25 and 99 0 caused no change in the hydrolysis products from either uranium mono- or dicarbide. HydrolysiS of uranium monocarbide­ dicarbide mixtures resulted in a linear decrease in the vol. % of methane, and linear increases in the percentages of hydrogen and C - to CR-hydro­ carbons in the gas as the combined-C/U atom ratio increase& from I.O to 1.85. Less methane was evolved from monocarbide - Oicarbide mixtures than expected from the monocarbide concentrations indicating that same poly­ merization of C units has occurred. * For publication in Inorganic Chemistry.

The proposed solutions are targeting better integration of trust in mobile network environment.
Non-intrusive blood glucose monitor by multi-task deep learning (2017)

Blood glucose concentration plays an important role in personal health. Hyperglycemia results in diabetes, leading to health risks such as pancreatic function failure, immunity reduce and ocular fundus diseases [6]. Meanwhile, hypoglycemia also brings complications such as confusion, shakiness, anxiety, and if not treated in time, coma or death [2]. People with diabetes need tight control of their blood glucose concentration to avoid both short-term and long-term physiological complications. In this work, we design BGMonitor, the first personalized smartphone-based non-invasive blood glucose monitoring system that detects abnormal blood glucose events by jointly tracking meal, drugs and insulin intake, physical activity and sleep quality. When BGMonitor detects an abnormal blood glucose event, it reminds the user to double-check by finger pricking or using clinical CGM devices.
Tyramide Signal Amplification for DNA and mRNA <i>In Situ</i> Hybridization (2006)

In situ hybridization (ISH) has significantly advanced the study of gene structure and expression in cells and tissues, but its application is often limited by detection sensitivity. The introduction of signal amplification after ISH using tyramides has greatly advanced in situ detection methods that also are now applicable in routine diagnostics. In this chapter, we provide detailed step-by-step protocols for synthesis of biotinylated tyramides, multiple-target deoxyribonucleic acid-ISH on cell preparations, both DNA- and messenger ribonucleic acid (mRNA)-ISH on formalin-fixed, paraffin-embedded tissue sections, and tyramide signal amplification for signal detection.
Activation of Molecular Hydrogen over a Binuclear Complex with Rh<sub>2</sub>S<sub>2</sub> Core:  DFT Calculations and NMR Mechanistic Studies (2004)

The dicationic complex [(triphos)Rh(mu-S)(2)Rh(triphos)](2+), 1 (modeled as 1c) [triphos = CH(3)C(CH(2)PPh(2))(3)], is known to activate two dihydrogen molecules and produce the bis(mu-hydrosulfido) product [(triphos)(H)Rh(mu-SH)(2)Rh(H)(triphos)](2+), 2 (modeled as 2b), from which 1 is reversibly obtained. The possible steps of the process have been investigated with DFT calculations. It has been found that each d(6) metal ion in 1c, with local square pyramidal geometry, is able to anchor one H(2) molecule in the side-on coordination. The step is followed by heterolytic splitting of the H-H bond over one adjacent and polarized Rh-S linkage. The process may be completed before the second H(2) molecule is added. Alternatively, both H(2) molecules are trapped by the Rh(2)S(2) core before being split in two distinct steps. Since the ambiguity could not be solved by calculations, (31)P and (1)H NMR experiments, including para-hydrogen techniques, have been performed to identify the actual pathway. In no case is there experimental evidence for any Rh-(eta(2)-H(2)) adduct, probably due to its very short lifetime. Conversely, (1)H NMR analysis of the hydride region indicates only one reaction intermediate which corresponds to the monohydride-mu-hydrosulfide complex [(triphos)Rh(H)(mu-SH)(mu-S)Rh(triphos)](2+) (3) (model 5a). This excludes the second hypothesized pathway. From an energetic viewpoint the computational results support the feasibility of the whole process. In fact, the highest energy for H(2) activation is 8.6 kcal mol(-1), while a larger but still surmountable barrier of 34.6 kcal mol(-1) is in line with the reversibility of the process.
Jointly Identifying Entities and Extracting Relations in Encyclopedia Text via A Graphical Model Approach (2010)

In this paper, we investigate the problem of entity identification and relation extraction from encyclopedia articles, and we propose a joint discriminative probabilistic model with arbitrary graphical structure to optimize all relevant subtasks simultaneously. This modeling offers a natural formalism for exploiting rich dependencies and interactions between relevant subtasks to capture mutual benefits, as well as a great flexibility to incorporate a large collection of arbitrary, overlapping and nonindependent features. We show the parameter estimation algorithm of this model. Moreover, we propose a new inference method, namely collective iterative classification (CIC), to find the most likely assignments for both entities and relations. We evaluate our model on real-world data from Wikipedia for this task, and compare with current state-of-the-art pipeline and joint models, demonstrating the effectiveness and feasibility of our approach. 1
Mixed Cooperative Adaptive Cruise Control for light commercial vehicles (2010)

In vehicle platooning, Adaptive Cruise Control (ACC) System controls the distance, relative velocity or more preferably time headway between preceding vehicles. Cooperative Adaptive Cruise Control System, on the other hand, uses vehicle to vehicle communication to gather information of vehicles further in front. Thus vehicles can follow each other at a closer distance, thereby improving traffic flow characteristics. This paper presents a new control approach by combining ACC and CACC algorithms and its application on light commercial vehicles. The new algorithm is tested for different single lane traffic simulations with dynamic models for loaded and unloaded vehicles. Delay and noise in the communication channels are also taken into account.
miRNAs in human cancer (2010)

Mature microRNAs (miRNAs) are single-stranded RNA molecules of 20-23 nucleotide (nt) length that control gene expression in many cellular processes. These molecules typically reduce the stability of mRNAs, including those of genes that mediate processes in tumorigenesis, such as inflammation, cell cycle regulation, stress response, differentiation, apoptosis and invasion. miRNA targeting is mostly achieved through specific base-pairing interactions between the 5' end ('seed' region) of the miRNA and sites within coding and untranslated regions (UTRs) of mRNAs; target sites in the 3' UTR lead to more effective mRNA destabilization. Since miRNAs frequently target hundreds of mRNAs, miRNA regulatory pathways are complex. To provide a critical overview of miRNA dysregulation in cancer, we first discuss the methods currently available for studying the role of miRNAs in cancer and then review miRNA genomic organization, biogenesis and mechanism of target recognition, examining how these processes are altered in tumorigenesis. Given the critical role miRNAs play in tumorigenesis processes and their disease-specific expression, they hold potential as therapeutic targets and novel biomarkers.
Layer-structured hexagonal (BN)C semiconductor alloys with tunable optical and electrical properties (2014)

Hexagonal boron nitride carbon, h(BN)1-x(C2)x, semiconductor alloys have been grown on sapphire substrates by metal-organic chemical vapor deposition. Bandgap tuning through compositional variation has been demonstrated via optical absorption measurements. Furthermore, an enhancement of approximately 10 orders of magnitude in the electrical conductivity has been attained by increasing the carbon concentration (x) from 0 to 0.21. Experimental results revealed evidences that the critical carbon concentration xc to form the homogenous h(BN)1-x(C2)x alloys, or the carbon solubility in hBN is about 3.2% at a growth temperature of 1300 °C before carbon clusters form. Based on the predicted phase diagram of cubic (BN)1-x(C2)x and the excellent matches in the structural and thermal properties of hBN and graphite, it is expected that homogenous h(BN)1-x(C2)x alloys with higher x can be achieved and the alloy miscibility gap can be reduced or completely removed by increasing the growth temperature. This is a huge advantage over the InGaN alloy system in which InN decomposes at high temperatures and high growth temperature cannot be utilized to close the miscibility gap. The results indicate that the h(BN)1-x(C2)x alloy system has the potential to tackle the challenging issues facing the emerging two-dimension materials beyond graphene, which include realizing the bandgap engineering, conductivity control, and large wafers of homogeneous films.
Physical Properties of Shark Gelatin Compared with Pig Gelatin (2000)

Physical properties of shark gelatin were examined during gel formation and postgelation in comparison with pig gelatin. Samples with various concentrations and pH values were evaluated by breaking strength, dynamic viscoelasticity, and dynamic light scattering. Sol-gel and gel-sol transition temperatures for shark gelatin were remarkably lower than those for pig gelatin. Shark gelatin gel shows a narrower pH range to form a stable gel compared with pig gelatin. Melting enthalpy of shark gelatin gel was greater than that of pig gelatin gel, and G' of shark gelatin gel changed more extensively with rising temperature in comparison with pig gelatin gel. It is concluded that shark gelatin has different characteristics from pig gelatin not only for gel characteristics but also for the solution property.
Nucleophilic Iron Catalysis in Transesterifications: Scope and Limitations (2010)

The ester bond is one of the most common structural motifs found in nature. Apart from the condensation between an acid and an alcohol, transesterifications represent another mechanistic alternative for the preparation of this compound class. The present paper summarizes our most recent investigations in this field, using nucleophilic iron complexes as catalysts for transesterifications under neutral conditions. This new type of metal catalyst complements the existing methodologies, which rely on Lewis acidic metal complexes. Investigations on scope and limitations, stereochemical course, and chemoselectivities will be presented.
Capacitance measurement technique in high density MOS structures (1980)

A precise capacitance measurement technique is described. This technique is based on a principle of capacitively devided a.c. voltage measurement. In test devices, reference and test capacitors are connected in series, and intermidiate node signal is monitored by on chip linear sense amplifier. Utilizing the technique, various capacitances were measured, and quantitativery compared with a two dimensional numerical analysis. The results indicate that the technique is practical and accurate for evaluating capacitive elements in VLSI's.
Adaptive Body Bias Aware Implementation for Ultra-Low-Voltage Designs in 22FDX Technology (2019)

A 0.5V ultra-low voltage Arm Cortex-M4F MCU in a 22nm FDSOI technology with 512kB SRAM and 140MHz operating frequency with 11.5μW/MHz is presented. An all-digital closed-loop continuous adaptive body biasing with individual P and N compensation and low ripple less than 30mV enables target performance from -40°C to 125°C and over full process corner range. The MCU has been implemented using an adaptive body bias aware implementation flow, which considers the corner tightening during implementation and sign-off for improved power, performance and area.
Coronary 'Y' stenting: a technique for angioplasty of bifurcation stenoses. (1996)

This report describes a case of successful percutaneous coronary transluminal angioplasty (PTCA) of a coronary artery bifurcating lesion using multiple intracoronary stents in an inverted 'Y' configuration. Balloon angioplasty of bifurcation coronary stenoses has a lower procedural success rate, higher restenosis rate and potential for side branch occlusion compared with nonbifurcation lesions. Numerous techniques, including two ('kissing') angioplasty balloons, have been used to overcome these problems. The authors believe that the technique described in this report, inserting stents into both branches simultaneously followed by a third proximal stent in a 'Y' configuration, allows successful dilatation of the bifurcation lesion while preserving flow into both branches and should be considered for similar complex anatomical subsets.
An analysis of load effects produced by ferrite core attachment (1997)

Ferrite core is installed in a cable and a wiring with a view to improving immunity to electromagnetic noise and reducing the electromagnetic noise generated by digital information devices. The impedance of the ferrite core at the installed location increases with frequency so that the noise current is suppressed. However, this mechanism has not been resolved theoretically in terms of the relationship between the core dimensions and the material constants. In this paper, the high frequency impedance generated by the ferrite core attachment is analyzed so that the equivalent circuit of the load effect is presented. Also, a method is presented for determination of the core shape that effectively enhances the load effect per unit length of the core with appropriate dimensions. Further, in order to confirm the validity of the equivalent circuit, measurement and calculation of the vector impedance are carried out. It is shown that both agree well and that the frequency dispersion parameter of the core permeability obtained from the circuit parameter satisfies Snoek's limit law. © 1997 Scripta Technica, Inc.

Application of nanofiber‐packed SPE for determination of salivary‐free cortisol using fluorescence precolumn derivatization and HPLC detection (2010)

Salivary cortisol has emerged as an easy-to-collect biologic marker of stress in many researches. In this study, we present a method for the determination of salivary-free cortisol using HPLC method with fluorescence precolumn derivatization, which is based on a novel extraction from the strongly acidic medium (fluorescent derivatives of cortisol in sulfuric acid medium) by electrospun polystyrene nanofibers packed SPE. For high-throughput sample extraction, an array pretreatment device based on nanofibers packed SPE micro-column was designed. The LOD of cortisol was 0.01 microg/L (S/N=3). The RSDs (n=6) for all analytes were below 8.0%, and the recoveries were 110, 102.4, and 99.4% (n=3) for saliva spiked with 0.1, 10, and 20 microg/L of cortisol, respectively. The proposed method was then successfully applied in the determination of free cortisol in human saliva. The salivary cortisol concentrations in the real samples ranged from 0.22 to 7.45 microg/L. The nanofiber-packed SPE overcame the low extraction recovery and bad clean-up effect of the conventional methods, and increased the sensitivity and selectivity of the method.

Complementary Resource Allocation for Variable-Size VoIP Packet in E-UTRA (2009)

For E-UTRA, semi-persistent scheduling has been adopted for Voice over Internet Protocol (VoIP) service. Semi- persistent scheduling is suitable for voice traffic which has constant rate characteristics and small packet size. However, the compressed VoIP packet after ROHC (Robust Header Compression) still has size variation. The variation of compressed VoIP packet size causes problem of packet segmentation propagation. In this paper a complementary resource allocation scheme is proposed. Complementary resource is notified to UEs along with predefined persistent pattern at the beginning of VoIP session. Complementary resource is allocated when VoIP packet with the sizes bigger than the size of predefined resource generated and blind decoding is implemented at the UE side. Simulation results show that the proposed scheme can reduce L1/L2 control signaling significantly while support large number of VoIP UEs compared with conventional solutions.
