Design of ultrahigh-speed low-voltage CMOS CML buffers and latches (2004)

A comprehensive study of ultrahigh-speed current-mode logic (CML) buffers along with the design of novel regenerative CML latches will be illustrated. First, a new design procedure to systematically design a chain of tapered CML buffers is proposed. Next, two new high-speed regenerative latch circuits capable of operating at ultrahigh-speed data rates will be introduced. Experimental results show a higher performance for the new latch architectures compared to the conventional CML latch circuit at ultrahigh-frequencies. It is also shown, both through the experiments and by using efficient analytical models, why CML buffers are better than CMOS inverters in high-speed low-voltage applications.
Ageing of acrylate‐based resins for stereolithography: thermal and humidity ageing behaviour studies (2008)

Purpose The purpose of this paper is to describe the ageing behaviour of acrylate‐based resins for stereolithography (SL) technology using different test methods and to investigate these effects on polymers. Design/methodology/approach Controlling the polymer degradation requires an understanding of many different phenomena, including the different chemical mechanisms underlying structural changes in polymer macromolecules, the influences of polymer morphology, the complexities of oxidation chemistry and the complex reaction pathways of polymer additives. Several ageing characterization experiments are given. Findings The paper covers the ageing process analysis of acrylate‐based polymers. An overview of the ageing behaviour is given, along with the bandwidth of material characteristics for a prolonged lifetime of this material class. Research limitations/implications For research and development in the field of rapid prototyping (RP) materials data about ageing behaviour and environmental effects are crucial. The authors show possible methods for measuring these effects and discuss the consequences in material research using a recently developed biocompatible SL resin as an example. Practical implications The study of the ageing behaviour of polymers is important for understanding their usability, storage, lifetime and recycling. The presented polymeric formulations are able to meet the growing demand for both soft and stiff manufacturing resin materials in the engineering and medical fields. Originality/value The analysis of the ageing behaviour of polymer materials is an important issue for engineering applications, recycling of post‐consumer plastic waste, as well as the use of polymers as biological implants and matrices for drug delivery and the lifetime of an article. The paper gives an overview of details involving ageing behaviour and their meaning for applications of acrylate‐based SL resins and is therefore of high importance to people with interest in long‐term behaviour and ageing of RP materials.

Biomimetically Engineered Polymeric Surfaces for Micro-scale Tribology (2006)

In this paper, we report on the replication of surface topography of natural leaf of Lotus onto thin polymeric films using a capillarity-directed soft lithographic technique. PDMS molds were used to replicate the surface. The replication was carried out on poly(methyl methacrylate) (PMMA) film coated on silicon wafer. The patterns so obtained were investigated for their friction properties at micro-scale using a ball-on-flat type micro-tribo tester, under reciprocating motion. Soda lime balls (1 mm diameter) were used as counterface sliders. Friction tests were conducted at a constant applied normal load of 3000 μN and speed of 1mm/s. All experiments were conducted at ambient temperature (24±1°C) and relative humidity (45±5%). Results showed that the patterned samples exhibited superior tribological properties when compared to the silicon wafer and nonpatterned sample (PMMA thin film). The reduced real area of contact projected by the surfaces was the main reason for their enhanced friction property.
Evaluation of design variables in Thompson coil based operating mechanisms for ultra-fast opening in hybrid AC and DC circuit breakers (2015)

The paper presents the operation transient analysis and multi-physics complexities in the design of a Thompson coil based ultra-fast mechanical switch for hybrid AC and DC circuit breakers. The electromagnetic, mechanical and thermal behavior of the switch has been analyzed through simulation using a multi-physics finite element software. The design variables have been classified into lumped circuit and geometric parameters; the sensitivity analysis by means of systematic and comprehensive simulations on these parameters helped establish the design guidelines. The switch has been designed with optimization for both the circuit parameters and geometrical dimensions of components targeting 2 mm travel for separation within 1 ms.

[The surfactant system of the lung as a functional unit]. (1984)

Morphological, biochemical and biophysical data indicate that the pulmonary surfactant system of the lung has to be considered as a functional unit from the alveoli to the trachea. In the nonciliated part of the air passages the surfactant assures the stability of the small airways and contributes to the transport processes. In the ciliated part of the air passages the surfactant supports indirectly the optimal transport of mucus due to its anti-glue properties. Any deterioration in the surfactant system results in functional consequences for lung mechanics and bronchial clearance mechanisms as discussed for RDS and COLD. Stimulation of surfactant synthesis and surfactant replacement can be regarded as new aspects for therapy.
Kinin B1 receptors mediate depression-like behavior response in stressed mice treated with systemic E. coli lipopolysaccharide (2010)

Our data show, for the first time, involvement of kinin B1 receptors in depressive behavioral responses, in a process likely associated with microglial activation and TNFα production. Thus, selective and orally active B1 receptor antagonists might well represent promising pharmacological tools for depression therapy.
Inrush Current Control of High Power Density DC–DC Converter (2020)

This paper presents a complete mathematical design of the main components of 2 kW, 54 direct current (DC)–DC converter stage, which can be used as the second stage of the two stages of alternating current (AC)–DC telecom power supply. In this paper, a simple inrush current controlling circuit to eliminate the high inrush current, which is generated due to high input capacitor at the input side of the DC–DC converter, is proposed, designed, and briefly discussed. The proposed circuit is very easy to implement in the lab using a single metal–oxide–semiconductor field-effect transistor (MOSFET) switch and some small passive elements. PSIM simulation has been used to test the power supply performance using the value of the designed components. Furthermore, the experimental setup of the designed power supply with inrush current control is built in the lab to show the practical performance of the designed power supply and to test the reliability of the proposed inrush current mitigation circuit to eliminate the high inrush current at initial power application to the power supply circuit. DC–DC power supply with phase shift zero voltage switching (ZVS) technique is chosen and designed due to its availability to achieve ZVS over the full load range at the primary side of the power supply, which reduces switching losses and offers high conversion efficiency. High power density DC–DC converter stage with smooth current startup operation, full load efficiency over 95%, and better voltage regulation is achieved in this work.
Multi-modal sensor data and information fusion for localization in indoor environments (2010)

The work presents the development of a framework for sensor data and complementary information fusion for localization in indoor environments. The framework is based on a modular and flexible sensor unit, which can be attached to a person and which contains various sensor types, such as range sensors, inertial and magnetic sensors or barometers. All measurements are processed within Bayesian Recursive Estimation algorithms and combined with available a priori knowledge such as map information or human motion models.
Effects of Hypoxia on Monocyte Inflammatory Mediator Production (2003)

Blood-derived monocytes are found at sites of inflammation as well as in solid tumors and atherosclerotic arteries. They are an abundant source of inflammatory eicosanoids such as prostaglandin E2 (PGE2) and thromboxane A2, which are formed via arachidonic acid (AA) metabolism by cyclooxygenase-1/2 (COX-1/2). In vitro studies of inflammatory mediator production are conducted invariably in room air, which does not reflect the oxygen tensions found in monocyte-containing lesions, which are frequently hypoxic. In this work we examined the effects of hypoxia at levels reported in these lesions, on monocyte COX-2 expression, the related events that lead to eicosanoid synthesis, and relationships with tumor necrosis factor (TNF)-alpha synthesis. In fresh human monocytes exposed to hypoxia (1% O2), there was an increase in COX-2 protein compared with cells in normoxia, and this was attributable to increased transcription and mRNA stability. However, the synthesis of PGE2 and thromboxane A2 was reduced in hypoxia and did not reflect the increased level of COX-2. Monocytes prelabeled with [3H]AA followed by lipopolysaccharide stimulation in the presence of hypoxia showed a reduced release of AA compared with cells in normoxia. In addition, hypoxia resulted in decreased phosphorylation of the p44/42 mitogen-activated protein kinase and of cytosolic phospholipase A2. Hypoxia also increased TNF-alpha synthesis, which appeared to play a role in COX-2 expression, and the observed increase TNF-alpha synthesis appeared to result from reduced PGE2 synthesis. Overall, the results suggest the existence of an autocrine loop of regulation between monocyte eicosanoid and TNF-alpha production, which is dysregulated in hypoxia and establishes hypoxia as being an important environmental determinant of inflammatory mediator production.

Cytokinins are central regulators of cambial activity (2008)

The roots and stems of dicotyledonous plants thicken by the cell proliferation in the cambium. Cambial proliferation changes in response to environmental factors; however, the molecular mechanisms that regulate cambial activity are largely unknown. The quadruple Arabidopsis thaliana mutant atipt1;3;5;7, in which 4 genes encoding cytokinin biosynthetic isopentenyltransferases are disrupted by T-DNA insertion, was unable to form cambium and showed reduced thickening of the root and stem. The atipt3 single mutant, which has moderately decreased levels of cytokinins, exhibited decreased root thickening without any other recognizable morphological changes. Addition of exogenously supplied cytokinins to atipt1;3;5;7 reactivated the cambium in a dose-dependent manner. When an atipt1;3;5;7 shoot scion was grafted onto WT root stock, both the root and shoot grew normally and trans-zeatin-type (tZ-type) cytokinins in the shoot were restored to WT levels, but isopentenyladenine-type cytokinins in the shoot remained unchanged. Conversely, when a WT shoot was grafted onto an atipt1;3;5;7 root, both the root and shoot grew normally and isopentenyladenine-type cytokinins in the root were restored to WT levels, but tZ-type cytokinins were only partially restored. Collectively, it can be concluded that cytokinins are important regulators of cambium development and that production of cytokinins in either the root or shoot is sufficient for normal development of both the root and shoot.
SMS-based platform for cardiovascular tele-monitoring (2008)

The focus of this paper is to describe a fully automatic platform to transmit, using the SMS service, medical data collected at home. The overall platform has two main components: a central server for SMS receiving (Central Receiving Unit, CRU) and the remote sending data collection and transmitting units (Home Transmitting Unit, HTU). HTU is connected to commercial meters of arterial pressure and blood glucose, and to a stepcounter. The CRU is located in a clinical center and acts also as a server for the database housing and for the users applications (data display, trend visualizations, alarms). Five platforms (CRU+5HTU) have been realized and given to patients. During a cumulative monitoring period of 251 days, there were 175 data transfer sessions, a mean of 35 plusmn 20 per patient. The stability of the telemonitoring system and the mean percentage of successful encoding of the transmitted data were 100%.
Fast Thermo-reflectance Bolometry (2003)

We present a new approach to bolometry based on the measurement of the optical reflectivity change of a thin metal layer deposited on a transparent substrate. The reflectivity change of the metal layer results from the temperature rise due to absorption of energetic particles or X-rays. With this spectrally broadband and fast technique measurements of absolute energy fluxes are possible. Contact-less sensing makes this method well suited for measurements in an environment with a strong electro-magnetic noise. The technique was applied to characterize a newly developed method for the generation of electron beams in dense gases. A very high efficiency for the e-beam generation, approaching 100%, was measured for the first time.

Tuning On–Off Current Ratio and Field-Effect Mobility in a MoS<sub>2</sub>–Graphene Heterostructure <i>via</i> Schottky Barrier Modulation (2014)

Field-effect transistor (FET) devices composed of a MoS2-graphene heterostructure can combine the advantages of high carrier mobility in graphene with the permanent band gap of MoS2 for digital applications. Herein, we investigate the electron transfer, photoluminescence, and gate-controlled carrier transport in such a heterostructure. We show that the junction is a Schottky barrier, whose height can be artificially controlled by gating or doping graphene. When the applied gate voltage (or the doping level) is zero, the photoexcited electron-hole pairs in monolayer MoS2 can be split by the heterojunction, significantly reducing the photoluminescence. By applying negative gate voltage (or p-doping) in graphene, the interlayer impedance formed between MoS2 and graphene exhibits an 100-fold increase. For the first time, we show that the gate-controlled interlayer Schottky impedance can be utilized to modulate carrier transport in graphene, significantly depleting the hole transport, but preserving the electron transport. Accordingly, we demonstrate a new type of FET device, which enables a controllable transition from NMOS digital to bipolar characteristics. In the NMOS digital regime, we report a very high room temperature on/off current ratio (ION/IOFF ∼ 36) in comparison to graphene-based FET devices without sacrificing the field-effect electron mobilities in graphene. By engineering the source/drain contact area, we further estimate that a higher value of ION/IOFF up to 100 can be obtained in the device architecture considered. The device architecture presented here may enable semiconducting behavior in graphene for digital and analogue electronics.

Dynamic software updates for real-time systems (2009)

Seamlessly updating software in running systems has recently gained momentum. Dynamically updating the software of real-time embedded systems, however, still poses numerous challenges: such systems must meet hard deadlines, cope with limited resources, and adhere to high safety standards.
