Wide-band tunable stimulated emission from a La/sub 3/Ga/sub 5/SiO/sub 14/-Cr/sup 3 +/ crystal (1987)

The authors report on wide-band tunable stimulated radiation (SR) in the near-IR range from La/sub 3/Ga/sub 5/SiO/sub 14/-Cr/sup 3 +/. The lasing spectrum parameters of La/sub 3/Ga/sub 5/SiO/sub 14/ and some of the most extensively studied oxygen and fluorine crystals containing Cr/sup 3 +/ are shown. Luminescence excitation spectrum is shown for Cr/sup 3 +/ in La/sub 3/Ga/sub 5/SiO/sub 14/. The authors attain and examine SR on a vibronic transition in Cr/sup 3 +/ in trigonal La/sub 3/Ga/sub 5/SiO/sub 14/ at 300 K and obtain the widest smooth SR tuning wavelength range for any inorganic material containing octahedral Cr/sup 3 +/ ions.
A performance evaluation of CP list scheduling heuristics for communication intensive task graphs (2002)

List-based priority schedulers have long been one of the dominant classes of static scheduling algorithms. Such heuristics have been predominantly based around the "critical path, most immediate successors first" (CP/MISF) priority. The ability of this type of scheduler to handle increased levels of communication overhead is examined in this paper. Three of the more popular list scheduling heuristics, HLFET and ISH and DSH, plus the mapping heuristic are subjected to a performance based comparison, with results demonstrating their inadequacies in communication-intensive cases. Performance degradation in these instances is partly due to the level alteration problem, but more significantly to conservative estimation of communication costs due to the assumption of zero link contention. The significance of this component of communication is also examined.
Primary-consistent soft-decision color demosaic for digital cameras (2004)

Bayer color mosaic sampling scheme is widely used in digital cameras. Given the resolution of CCD sensor arrays, the image quality of digital cameras using Bayer sampling mosaic largely depends on the performance of the color demosaic process. A common and serious weakness shared by all existing color demosaic algorithms is an inconsistency of sample interpolations in different primary color components, which is the culprit for the most objectionable color artifacts. To cure the problem we propose a primary-consistent color demosaic algorithm. The performance of this algorithm is further enhanced by a soft-decision sample interpolation scheme. Experiments demonstrate that the proposed framework of primary-consistent soft-decision color demosaic can significantly improve the image quality of digital cameras.
Preconditioning of NOD mice with anti-CD8 mAb and costimulatory blockade enhances chimerism and tolerance and prevents diabetes, while depletion of αβ-TCR+ and CD4+ cells negates the effect (2004)

Bone marrow transplantation blocks diabetes pathogenesis and reverses autoimmunity in nonobese diabetic (NOD) mice. However, there is a greater barrier to engraftment in the context of autoimmunity. In the present study, we characterized which recipient cells influence engraftment in prediabetic NOD mice, with the goal to replace myelotoxic conditioning with antigen-specific deletion of reactive host cells. Preconditioning of NOD mice with anti-CD8 and anti-CD154 monoclonal antibodies (mAbs) synergistically enhanced engraftment and significantly reduced the minimum total body irradiation (TBI) dose for engraftment. Strikingly, preconditioning with anti-CD4 mAb significantly impaired engraftment, negating the beneficial effect of anti-CD8, and resulted in a requirement for more TBI-based conditioning compared with controls conditioned with TBI alone. Similarly, more TBI was required when anti-T-cell receptor beta (TCRbeta) mAb was administered as preconditioning. The addition of anti-CD152 to CD154 preconditioning abrogated the engraftment-enhancing effect of anti-CD154. Taken together, these data indicate a role for CD4+ regulatory T cells in vivo which require signaling via CD152 in the induction of chimerism and tolerance in NOD recipients. Notably, disease prevention and reversal of autoimmunity was absolutely correlated with the establishment of chimerism. These studies have important implications for the design of novel clinical approaches to treat type 1 diabetes.
Porous Protein Crystals as Reaction Vessels for Controlling Magnetic Properties of Nanoparticles (2012)

Magnetic bimetallic CoPt nanoparticles are synthesized in the solvent channels of hen egg white lysozyme crystals by the reduction of Co(2+) and Pt(2+) ions pre-organized on the interior surface of the solvent channels. By using different lysozyme crystal systems, the magnetic properties of CoPt nanoparticles can be controlled.
Reactions and Utilizations of Higher Alkylene Oxides (1965)

Reactions and utilizations of higher alkylene oxides were investigated. The used oxides were 1, 2-epoxyoctane, 1, 2-epoxydecane and 1, 2-epoxydodecane synthesized from corresponding α-olefins by using peracetic acid. These oxides reacted easily with some organic acids, hydroxy compounds and amino compounds as compounds having active hydrogen. Higher alkylene oxides reacted also with benzene in the presence of aluminium chloride and could be polymerized in the presence of the same catalysts that had been used for the polymerizations of lower alkylene oxides. Furthermore, utilizations of the products in the reactions of oxides with some compounds having active hydrogen were investigated.
The Photochlorination and the Chlorine-Sensitized Photo-oxidation of Gaseous Tetrachloroethylene (1934)

In the absence of oxygen, the illumination of a carbon tetrachloride solution of chlorine and tetrachloroethylene with blue light has been found to bring about chlorination which proceeds as a chain reaction with a large quantum yield and at a rate proportional to the square root of the intensity of illumination. In the presence of oxygen, the chlorination is strongly inhibited and instead there occurs a chlorine-sensitized oxidation to trichloroacetyl chloride and phosgene; this reaction proceeds in solution with a comparatively small quantum yield and at a rate proportional to the first power of the light intensity. It was found possible to account for the kinetics of the chlorination by either of two simple and plausible reaction schemes, one involving C_2Cl_5 and the other Cl_3.

BRCA1 and acetyl‐CoA carboxylase: The metabolic syndrome of breast cancer (2007)

Breast cancer-associated mutations affecting the highly-conserved C-terminal BRCT domains of the tumor suppressor gene breast cancer susceptibility gene 1 (BRCA1) fully disrupt the ability of BRCA1 to interact with acetyl coenzyme A carboxylase alpha (ACCA), the rate-limiting enzyme catalyzing de novo fatty acid biogenesis. Specifically, BRCA1 interacts solely with the phosphorylated (inactive) form of ACCA (P-ACCA), and the formation of the BRCA1/P-ACCA complex interferes with ACCA activity by preventing P-ACCA dephosphorylation. One of the hallmarks of aggressive cancer cells is a high rate of energy-consuming anabolic processes driving the synthesis of lipids, proteins, and DNA (all of which are regulated by the energy status of the cell). The ability of BRCA1 to stabilize the phosphorylated/inactive form of ACCA strongly suggests that the tumor suppressive function of BRCA1 closely depends on its ability to mimic a cellular-low-energy status, which is known to block tumor cell anabolism and suppress the malignant phenotype. Interestingly, physical exercise and lack of obesity in adolescence have been associated with significantly delayed breast cancer onset for Ashkenazi Jewish women carrying BRCA1 gene mutations. Further clinical work may explore a chemopreventative role of "low-energy-mimickers" deactivating the ACCA-driven "lipogenic phenotype" in women with inherited mutations in BRCA1. This goal might be obtained with current therapeutic approaches useful in treating the metabolic syndrome and associated disorders in humans (e.g., type 2 diabetes and obesity), including metformin, thiazolidinediones (TZDs), calorie deprivation, and exercise. Alternatively, new forthcoming ACCA inhibitors may be relevant in the management of BRCA1-dependent breast cancer susceptibility and development.

Design of a Closed-Loop, Bidirectional Brain Machine Interface System With Energy Efficient Neural Feature Extraction and PID Control (2016)

This paper presents a bidirectional brain machine interface (BMI) microsystem designed for closed-loop neuroscience research, especially experiments in freely behaving animals. The system-on-chip (SoC) consists of 16-channel neural recording front-ends, neural feature extraction units, 16-channel programmable neural stimulator back-ends, in-channel programmable closed-loop controllers, global analog-digital converters (ADC), and peripheral circuits. The proposed neural feature extraction units includes 1) an ultra low-power neural energy extraction unit enabling a 64-step natural logarithmic domain frequency tuning, and 2) a current-mode action potential (AP) detection unit with time-amplitude window discriminator. A programmable proportional-integral-derivative (PID) controller has been integrated in each channel enabling a various of closed-loop operations. The implemented ADCs include a 10-bit voltage-mode successive approximation register (SAR) ADC for the digitization of the neural feature outputs and/or local field potential (LFP) outputs, and an 8-bit current-mode SAR ADC for the digitization of the action potential outputs. The multi-mode stimulator can be programmed to perform monopolar or bipolar, symmetrical or asymmetrical charge balanced stimulation with a maximum current of 4 mA in an arbitrary channel configuration. The chip has been fabricated in 0.18 μ m CMOS technology, occupying a silicon area of 3.7 mm <sup>2</sup>. The chip dissipates 56 μW/ch on average. General purpose low-power microcontroller with Bluetooth module are integrated in the system to provide wireless link and SoC configuration. Methods, circuit techniques and system topology proposed in this work can be used in a wide range of relevant neurophysiology research, especially closed-loop BMI experiments.

Degradable Polymers and Materials (2006)

This book describes some recent developments in natural and synthetic degradable and biodegradable polymers and materials, including their synthesis and assembly, characterization and degradation studies, as well as the design and exploration of such materials for specific and alternative eco-friendly and sustainable applications to conventional polymers and materials. The twenty five chapters in this book have been written by world's leading researchers in their respective areas. Here, these chapters have been organized in the order such that they describe advances in natural polymers, natural and synthetic polymers, polymer synthesis, characterization and finally degradation mechanisms. Several chapters of this book are dedicated to natural polymers, which are inherently biodegradable due to their natural origin. Chemical modifications of natural polymers lead to enhanced properties, typically tailored to specific applications and it is often possible to sustain biodegradability despite chemical conversions of the natural polymers. Since ester bonds readily undergo hydrolysis, various
Poled polymers for sensors and photonic applications (1996)

A brief survey of the electrical and optical properties of poled polymer electrets for sensors and photonic applications is given. Semicrystalline ferroelectric polymers are highly suitable for piezo- and pyroelectric applications, while amorphous polymers containing molecular dipoles with acceptor and donor groups linked by delocalized π electrons (A-π-D) are interesting for photonic applications. The large variety of poling techniques, such as electrode, corona, electron-beam, and photothermal poling, is discussed in detail together with specifically developed poling techniques for ferroelectric or amorphous polymers. Methods for the experimental investigation of the polar order are based on the piezo-, and pyroelectric effect, birefringence, the electro-optical effect and second-harmonic generation. Newly developed thermal analysis techniques and dipole relaxation spectroscopies complement traditional techniques, such as thermally stimulated depolarization and broadband linear and nonlinear dielectric relaxation spectroscopy. The compatibility of polymers with semiconductor technology is illustrated with selected applications in hybrid integrated thermal and acoustical imaging devices, electro-optical modulators and second-harmonic generators.
Transcranial Doppler–Detected Microemboli in Patients With Acute Stroke (1995)

Background and Purpose Transcranial Doppler sonography (TCD) has been used to detect microembolic signals in a variety of clinical situations. We studied the prevalence of TCD-detected microemboli in 38 acute stroke patients. Methods Consecutive patients with acute anterior circulation stroke were stratified into high-risk (group 1), medium-risk (group 2), and low-risk (group 3) groups based on their risk factors for cerebral embolism. Results Microemboli were detected in 11% of patients. They were present in 17% of group 1, 10% of group 2, and 0% of group 3 patients. Emboli were present in patients with mechanical prosthetic valves, carotid stenosis (>70%), and mitral valve strands with a patent foramen ovale. Patients with microemboli more frequently had a history of cerebral ischemia compared with patients without microemboli ( P <.05). They also more frequently had recent (<3 months) symptoms compared with patients without microemboli ( P <.05). In patients with a cardiac source of embolization, the number of microemboli detected was directly proportional to the acuity of previous symptoms. Conclusions These data suggest that TCD-detected microemboli are associated with an increased prevalence of prior cerebrovascular ischemia. The presence of TCD-detected microemboli could be a risk factor for cerebrovascular ischemia.
High‐Current‐Density Monolayer CdSe/ZnS Quantum Dot Light‐Emitting Devices with Oxide Electrodes (2011)

Films of semiconductor quantum dots (QDs) are promising for lighting technologies, but controlling how current flows through QD films remains a challenge. A new design for a QD light-emitting device that uses atomic layer deposition to fill the interstices between QDs with insulating oxide is introduced. It funnels current through the QDs themselves, thus increasing the light emission yield.
The MPFA: A multiple-place foraging algorithm for biologically-inspired robot swarms (2016)

Finding and retrieving resources in unmapped environments is an important and difficult challenge for robot swarms. Central-place foraging algorithms can be tuned to produce efficient collective strategies for different resource distributions. However, efficiency decreases as swarm size scales up: larger swarms produce more inter-robot collisions and increase competition for resources. We propose a novel extension to central-place foraging in which multiple nests are distributed in the environment. In this multiple-place foraging algorithm, robots depart from a home nest but always return to the nest closest to them. We simulate robot swarms that mimic foraging ants using the multiple-place strategy, employing a genetic algorithm to optimize their behavior in the robot simulator ARGoS. Experiments show that multiple nests produce higher foraging rates and lower average travel time compared to central-place foraging for three different resource distributions. Time spent avoiding robot-robot collisions is not always reduced as was expected, primarily because the use of pheromone-like waypoints leads to more collisions when robots forage for clustered resources. These results demonstrate the importance of careful design in order to create efficient multiple collection points to mitigate the central-place bottleneck for foraging robot swarms.
Networking issues in IP multicast over satellite (2003)

Abstract This paper describes the issues that arise when using satellites for IP multicast, with the emphasis on multicast protocols and how their implementation depends on the satellite communications platform. Various link layer standards such as DVB‐S, DVB‐RCS and ATM can be used in satellites with on‐board processing, and applied to meet user and network requirements for IP multicast. The paper provides an overview of the networking issues and their interactions. Specifically, we show how multicast networking protocols have to be modified to take into account the satellite link characteristics: these protocols include IGMP, multicast routing protocols and reliable multicast protocols. We also discuss how security systems support IP multicast. Copyright © 2003 John Wiley & Sons, Ltd.
Accurate in-situ runtime measurement of energy per operation of system-on-chip on FPGA (2015)

Accurate energy estimates for applications running on FPGA based processors at runtime can enable advanced energy management algorithms to dynamically tune the system to optimize its energy consumption and in turn increase the battery life in the mobile systems. This paper presents an online methodology to monitor energy per instruction on FPGA platform that can be used to accurately estimate energy consumed by the application at runtime that is chip specific and suppresses effects of noise. We then extend this methodology to account for energy consumed by the peripherals. Results suggest our methodology is immune to noise and can estimate energy online with less than 3% deviation from total measured energy at less than 2% measurement overhead.

Acceleration of Wound Healing by Gelatin Film Dressings with Epidermal Growth Factor (2005)

We examined in vivo efficiency of a gelatin film sheet with epidermal growth factor (EGF) for a novel therapeutic device for cutaneous wound repair. NIH3T3 fibroblasts and PAM212 keratinocytes proliferated when the cells were incubated with the homogenate of EGF containing gelatin sheets, indicating that the gelatin sheet retained biologic activity of EGF in the process of sheet formation. To evaluate therapeutic effects, the EGF containing gelatin sheets or control sheets were applied onto partial-thickness skin wounds made on dorsa of hairless dogs. Wound closure in wounds treated with EGF containing gelatin sheets was accelerated when compared to that of wounds treated with control sheets, exhibiting earlier reepithelialization of the epidermis and highly regulated repair of extracellular matrix in the dermis. Therefore, we concluded that the gelatin film is a useful material to keep EGF stable and the EGF containing sheet has the ability to become an efficient therapeutic agent for superficial or deep partial-thickness wounds in the skin.
Micro-Hole Drilling on Glass Substrates—A Review (2017)

Glass micromachining is currently becoming essential for the fabrication of micro-devices, including micro- optical-electro-mechanical-systems (MOEMS), miniaturized total analysis systems (μTAS) and microfluidic devices for biosensing. Moreover, glass is radio frequency (RF) transparent, making it an excellent material for sensor and energy transmission devices. Advancements are constantly being made in this field, yet machining smooth through-glass vias (TGVs) with high aspect ratio remains challenging due to poor glass machinability. As TGVs are required for several micro-devices, intensive research is being carried out on numerous glass micromachining technologies. This paper reviews established and emerging technologies for glass micro-hole drilling, describing their principles of operation and characteristics, and their advantages and disadvantages. These technologies are sorted into four machining categories: mechanical, thermal, chemical, and hybrid machining (which combines several machining methods). Achieved features by these methods are summarized in a table and presented in two graphs. We believe that this paper will be a valuable resource for researchers working in the field of glass micromachining as it provides a comprehensive review of the different glass micromachining technologies. It will be a useful guide for advancing these techniques and establishing new hybrid ones, especially since this is the first broad review in this field.
A low-common mode noise and high-efficiency buck-buck-boost inverter (2013)

This paper presents a new inverter topology, buck-buck-boost (B3) inverter, which is derived from an H-bridge converter with additional switch legs (HA converter). With its simple circuit structure and expandability, the proposed inverter demonstrates low common mode noise due to its solid connection between the grounds of the input and output terminals. The proposed inverter is especially advantageous in photovoltaic power conditioning system of which large parasitic capacitances are prone to generated common-mode electromagnetic interference (EMI). In this paper, circuit structure, operation, and control strategy of the B3 inverter are designed. Experimental results verify that the proposed inverter shows lower noise and higher efficiency than conventional inverter.
