[Platelet aggregation inhibitors and vitamin K antagonists in stomatology and maxillo-facial surgery]. (2003)

Anti-thrombin, anti-platelet and anti-vitamin K agents are common treatments given for the prevention of thrombotic or embolic events. In oral or maxillofacial surgery, the question is whether oral anticoagulants or anti-platelets should be discontinued or not: temporary interruption could limit the risk of bleeding, but would increase the risk of thrombosis, and inversely. The best risk/benefit ratio must be achieved, but in many cases anti-platelet agents or even anti-vitamin K agents can be continued. In case of "potentially hemorrhagic" oral surgery, anti-platelet agents should be interrupted about ten days before the intervention. Anti-vitamin K agents should be interrupted four days before surgery and if required, replaced by low-molecular weight heparin at preventive or curative doses. In the very large majority of patients however, surgery (avulsion for example) can be performed without interrupting anticoagulation. Data in the literature have demonstrated that despite the theoretical risk of hemorrhage, bleeding is minimal and can be easily controlled by local treatments; the risk of thrombotic or thromboembolic events after discontinuing anticoagulation is much greater. A close collaboration between the dentist, the stomatologist, and the clinician is required to determine whether anti-thrombosis prevention should be continued and whether the anticoagulation level is adapted to the thrombotic risk. Good surgical technique and local anti-hemorrhagic treatment are essential in oral surgery, particularly in patients taking anti-platelets or oral anticoagulants.
Numerical Solution of the spin-$\frac {3}{2}$ Heisenberg Antiferromagnetic Chains Using a Projector Method (1993)

An efficient projector method is used to calculate the energies of the ground state and the first excited state, and hence the energy gap between them, of the spin- Heisenberg antiferromagnetic chains with linear sizes up to . For the chains up to the exact results are obtained, and for longer chains up to they are estimated by imposing on Monte Carlo technique. It is found that the size dependence of the ground state energy per site has the form of , and the value of the ground state energy per site as is . Our results show that the energy gap trends to zero as , which is consistent with the rigorous proof.
Cluster devices/interconnects for nanotechnology (2008)

Integrated circuit (IC) technology has evolved rapidly but the continual development of transistors and interconnects (the connection between the transistors) is facing greater and greater challenges, which require new materials and new processes. Research in nano-particles (or nanoscale clusters) creates possibilities for both new materials and new processes. This thesis explores the electrical properties of amorphous antimony clusters and develops a new copper cluster deposition technique for application to transistors and interconnects respectively. For amorphous antimony clusters, an electron diffraction technique was applied to identify the phase of the clusters prior to deposition on electrically contacted samples. The deposition process produced uniform cluster films suitable for electrical measurements. A consistent percolation exponent for conduction (t=1.85) was obtained. After deposition, the resistance of the films continued to increase because of coalescence. Although it was previously reported that amorphous antimony films were semiconducting, from linear I(V) curves, a low temperature coefficient of resistance (10⁻⁴ K⁻¹) and no observable gate effect, it was found that the antimony cluster films in this study were not semiconducting, possibly due to the effect of coalescence. The development of the copper clusters for the interconnects application was very successful. Trenches of sub-200 nm widths, with different diffusion barriers and seed layers, and up to 5:1 aspect ratios have been completely filled with copper clusters. Due to the propensity for reflection of clusters from the planar surfaces between trenches, the process results in selective deposition into the trenches and bottom up filling is demonstrated. After annealing in hydrogen or in vacuum, the clusters sinter into a copper seed layer. The resistivity measured by a thin film four-point probe (1.6 - 2.3 × 10⁻⁸ Ωm) meets the requirement by industry (2.2 × 10⁻⁸ Ωm). The process is therefore promising for industrial application, but further testing and investigation of integration issues is required.
Development and Application of Moisture Control System with IR Moisture Sensor to Aqueous Polymeric Coating Process. (1993)

A new practical method of controlling the moisture content of particles in an aqueous polymeric coating by a tumbling fluidized bed is described. The method was based on the on-line measurement and feedback control of moisture content by use of an IR (infrared) moisture sensor. Spherical core particles made of crystalline cellulose were coated in the tumbling fluidized bed by atomizing the suspension of enteric acrylic copolymer (Eudragit L30D-55). The influence of moisture control, conducted with different methods (PID (proportional-integral-derivative) control and on-off control), on the drug release rate and on the agglomeration tendency of coated particles was investigated. It was found that moisture control by the PID control method was useful for producing the desired coated particles which exhibited excellent properties in delayed release with a low agglomeration tendency.
Tests of disk type magnetic flux pump with the ability of high voltage output (1997)

Using a superconducting magnetic flux pump, thick power leads for a superconducting magnet could be replaced with thin string leads to excite the excitation magnet of the superconducting flux pump. We have developed a new type of flux pump with high-voltage output to shorten the charge and discharge time of the load magnet. The test of the pump with four stacked disks as the exciter for the load magnet has been carried out. This disk type flux pump yielded 70 mV of voltage across its terminal and 10 A of current through a 85 mH load magnet which was the field winding of 20 kVA class fully superconducting generator within 12 seconds. This output voltage of the new flux pump is about 10 times larger than that of our previous work. Moreover since it is easy to stack disks for a superconducting flux pump, the high-voltage exciter for a 1 H class superconducting magnet could be expected to be made easily.
Asymmetric Synthesis of 2-Substituted Azetidin-3-ones via Metalated SAMP/RAMP Hydrazones (2016)

2-Substituted azetidin-3-ones can be prepared in good yields and enantioselectivities (up to 85% ee) by a one-pot procedure involving the metalation of the SAMP/RAMP hydrazones of N-Boc-azetidin-3-one, reaction with a wide range of electrophiles, including alkyl, allyl, and benzyl halides and carbonyl compounds, followed by hydrolysis using oxalic acid.
Migration of legacy test programs to modern programming environments (2002)

As we prepare to enter the new millennium, very valuable software programs written decades ago have become antiquated as new hardware has been developed and as software theories and management theories have changed. One area of software that has been greatly affected by these changes is the area of test programs (TPs). These programs often contain tens of thousands of lines of code and have been written in computer languages that have been in existence for almost half a century. This class of so-called legacy program code is written in such languages as ATLAS, BASIC, JOVIAL, FORTRAN, etc. Now with a dwindling defense budget and an increased availability of lower cost commercially based test instruments utilizing components based on VXI/PXI technology, re-hosting of legacy test programs onto new test platforms is an attractive alternative to writing new software. In this way major industries such as the military and avionics manufacturers can take advantage of COTS tools for building their new test systems. These tools include PC plug-in boards, VXI/IVI plug-play instrument drivers, and LabVIEW and LabWindows/CVI test software tools, etc. This migration affords the industries the benefits from the high volumes, lower prices and better worldwide compatibility and support that are common with COTS tools. Unfortunately, any migration to modern programming environments has to consider either rewriting very valuable legacy computer software or manually converting it, both prospects being extremely time consuming and expensive because of the magnitude of the task. Thus, there is a need for a conversion tool that can accept legacy software, and produce software in a language or dialect that is compatible with the modern software environments (e.g., LabWindows/CVI, LabVIEW, Visual Basic, Visual C++, and new versions of ATLAS). This paper highlights the features and benefits of such a tool.
Benefits of Aloe vera in dentistry (2015)

Aloe vera (Aloe barbadensis) is a plant that belongs to Liliaceae family. The name Aloe derives from the Arabic word "Alloeh" meaning shining bitter substance while "vera" in Latin means true. It contains various minerals and vitamins. It has got various properties such as immunomodulatory, antiviral and antiinflammatory in nature. A. vera can play a significant role in dentistry in treatment of lichen planus, oral submucous fibrosis, recurrent aphthous stomatitis, alveolar osteitis, periodontitis, etc.
LiNbO<sub>3</sub> optical waveguide modulator for bidirectional transmission (1994)

Abstract A new bidirectional external optical modulator using Fresnel reflection light has been proposed and developed. Since weak light reflected from the end of a crystal can be modulated in this modulator, no laser source is required if the modulator is intended for home use. This modulator also has no significant effect on a video signal in the downstream. In the external modulator designed for trial use, insertion loss was less than 3 dB, the half‐wave voltage was 10 V, and the half‐wave voltage difference and phase difference between the two modes were 2 percent and 5 degrees. A small module of the present device was created for use in a home optical terminal station of a demand access‐type Hivision CATV system. In this bidirectional transmission experiment, stable channel selection and good Hivision receiving image with C/N > 20 dB were confirmed. For the uplink 64 kbit/s NRZ signal, bit error rate (BER) of less than 10 −8 was obtained.
MEKK3 is essential for lipopolysaccharide‐induced interleukin‐6 and granulocyte–macrophage colony‐stimulating factor production in macrophages (2006)

Mitogen-activated protein/ERK kinase kinase 3 (MEKK3) is a Ser/Thr protein kinase belonging to the MEKK/STE11 subgroup of the MAP3K family. Recently, we found that MEKK3 plays a critical role in interleukin-1 (IL-1) receptor and Toll-like receptor 4 signalling using established primary mouse embryonic fibroblast (MEF) cell lines. However, the function of MEKK3 in immune cells has not been studied because germ-line MEKK3 knockout mice are embryonically lethal between embryonic days 10 and 11. In this study, we used small interference RNA to the mouse Mekk3 gene to specifically knock down MEKK3 expression in the macrophage line Raw264.7. We found that the lipopolysaccharide-induced IL-6 and granulocyte-macrophage colony-stimulating factor (GM-CSF) production was dramatically decreased in MEKK3 knockdown cells whereas the tumour necrosis factor-alpha and IL-1beta production were not affected. We also observed that the ERK1/2, p38 and JNK MAPK induction in MEKK3 knockdown cells were moderately inhibited within the first 60 min of stimulation, while the ERK and p38 were more severely inhibited after 2-4 hr of stimulation. Degradation of IkappaBalpha was also partially blocked in MEKK3 knockdown cells. Notably, the impairment in IL-6 and GM-CSF production in the MEKK3 knockdown cells was restored by reintroducing a human Mekk3 cDNA that could not be targeted by mouse Mekk3-siRNAs. In conclusion, this study showed that MEKK3 is a crucial and specific regulator of the proinflammatory cytokines IL-6 and GM-CSF in macrophages and provided a novel method for investigating MEKK3 function in other immune cells.

Enhancing spark's contract checking facilities using symbolic execution (2011)

Spark, a subset of Ada for engineering safety and security-critical systems, is one of the best commercially available frameworks for formal-methods-supported development of critical software. Spark is designed for verification and includes a software contract language for specifying functional properties of procedures. Even though Spark and its static analysis components are beneficial and easy to use, its contract language is rarely used for stating properties beyond simple constraints on scalar values due to the burdens the associated tool support imposes on developers. Symbolic execution (SymExe) techniques have made significant strides in automating reasoning about deep semantic properties of source code. However, most work on SymExe has focused on bug-finding and test case generation as opposed to tasks that are more verification-oriented such as contract checking. In previous work we have presented: (a) SymExe techniques for checking software contracts in embedded critical systems, and (b) Bakar Kiasan, a tool that implements these techniques in an integrated development environment for Spark. In this paper, we give a detailed walk-through of Bakar Kiasan as it is applied to an industrial code base for an embedded security device. We illustrate how Bakar Kiasan provides significant increases in automation, usability, and functionality over existing Spark contract checking tools, and we present results from performance evaluations of its application to industrial examples.
Big data, smart computer systems, and doctor–patient relationship (2016)

This editorial refers to ‘Machine learning for prediction of all-cause mortality in patient with suspected coronary artery disease: a 5-year multicentre prospective registry analysis’, by M. Motwani et al ., doi:10.1093/eurheartj/ehw188 

Decision-making in medicine is based on the factual knowledge of the physician/practitioner, but is significantly influenced by various humanistic factors that play a role in the physician–patient relationship. Despite the increasing amount of electronic data available ‘online’ during the patient encounter, the ability to utilize a patient-centred approach is a central quality of superior practitioners. However, electronic health records (EHRs) and use of smart computer systems are having an increasing impact on established approaches in medicine.

The basic EHR collects and stores all data generated in a healthcare system (e.g. clinical notes, test results, and imaging studies). In addition to these data traditionally generated within the clinical setting, there are several novel feeds of information that can impact patient care. Specifically, wearable devices, and information from sensors and apps that capture and track various environmental, socio-economic, and other personal data can be valuable in understanding an individual's health status …
Scalable and efficient broadcasting algorithms for very large internetworks (2002)

Most dynamic broadcasting techniques for large networks including the Internet suffer from scalability problems, i.e., they are not efficient with respect to the tremendous size of today's networks. We propose a distributed scalable broadcast algorithm for the Internet. Moreover our scheme attempts to optimize both cost of routing and broadcast time performance measures. Utilizing the hierarchical structure of the Internet, cost optimal protocols are proposed using a distributed spanning tree algorithm while near-optimal time broadcast can be achieved by formulating the problem as finding maximum matching in bipartite graphs. Simulation results obtained prove the validity and feasibility of the scheme.
Autoregressive modeling of lung sounds: characterization of source and transmission (1989)

In this communication, we discuss the application of autoregressive modeling to lung sounds analysis. The lung sounds source in the airway is modeled as a white noise source, consisting of one or a combination of the following sources: random white noise sequence, periodic train of impulses, and impulsive bursts of energy. The acoustic transmission through the lung parenchyma and chest wall is modeled as an all-pole filter. Using this method, the source and transmission characteristics of lung sounds are estimated separately, based on the lung sounds at the chest wall. To illustrate the potential validity of the model, lung sound segments in known disease conditions were selected from teaching tapes and the source and transmission characteristics were estimated by applying the model. The estimated characteristics were found to be consistent with current knowledge of the generation and transmission of lung sounds in the known conditions.

A study on the hybrid image coding and structuring methods for multimedia scalability packages communication services (2003)

Multimedia communication services based on standard information, such as MPEG-1, MPEG-2, H.261 and H.263, have been demonstrated using multimedia scalability packages, which can provide multimedia information with user functionality and availability. We propose a video information architecture coding method for these packages, called MSP (Multimedia Scalability Packages). The MSP data architecture is defined using hierarchical architectures. We consider in particular temporal feature information. The temporal scalability concept is described by both MSP data and scalability content data. As coding schemes, we consider video hybrid scalability using spatial and temporal scalability and show some scalability profiles. Finally, we explain the new video temporal function by MSP data description.

Polymerization of novel methacrylated anthraquinone dyes (2013)

A new series of polymerizable methacrylated anthraquinone dyes has been synthesized by nucleophilic aromatic substitution reactions and subsequent methacrylation. Thereby, green 5,8-bis(4-(2-methacryloxyethyl)phenylamino)-1,4-dihydroxyanthraquinone (2), blue 1,4-bis(4-((2-methacryloxyethyl)oxy)phenylamino)anthraquinone (6) and red 1-((2-methacryloxy-1,1-dimethylethyl)amino)anthraquinone (12), as well as 1-((1,3-dimethacryloxy-2-methylpropan-2-yl)amino)anthraquinone (15) were obtained. By mixing of these brilliant dyes in different ratios and concentrations, a broad color spectrum can be generated. After methacrylation, the monomeric dyes can be covalently emplaced into several copolymers. Due to two polymerizable functionalities, they can act as cross-linking agents. Thus, diffusion out of the polymer can be avoided, which increases the physiological compatibility and makes the dyes promising compounds for medical applications, such as iris implants.
CCL21 Cancer Immunotherapy (2014)

Cancer, a major health problem, affects 12 million people worldwide every year. With surgery and chemo-radiation the long term survival rate for the majority of cancer patients is dismal. Thus novel treatments are urgently needed. Immunotherapy, the harnessing of the immune system to destroy cancer cells is an attractive option with potential for long term anti-tumor benefit. Cytokines are biological response modifiers that stimulate anti-tumor immune responses. In this review, we discuss the anti-tumor efficacy of the chemotactic cytokine CCL21 and its pre-clinical and clinical application in cancer.
Genetic Identification of Hybrids between Rhodeus uyekii and R. notatus by Sequence Analysis of RAG-1 Gene (2009)

Reciprocal interspecific hybrids between two bitterling species Rhodeus uyekii (RU) and R. notatus (RN) were genetically identified based on the partial sequence analysis of recombination activating gene-1 (RAG-1) gene. Out of 863 bp positions analyzed, 13 nucleotide substitutions were detected between the two parental species (RU and RN genotypes). Both the induced hybrids (RU femaleRN male; UN genotype) and their reciprocal counterparts (RN femaleRU male; NU genotype) displayed the double peaks (or polymorphism) of sequence chromatograms at the 13 diagnostic positions, indicating that those hybrids were actual karyogamy derived from the two parental haploid genomes. However, it was not possible to distinguish between the reciprocal interspecific hybrids.
