Impact of Point Defects on the Luminescence Properties of (Al,Ga)N (2008)

Threading dislocations (TDs) in (Al,In,Ga)N semiconductors are known to affect the luminescence efficiency of near-band-edge (NBE) emissions in bulk films and quantum structures. However, the principal role of point defects such as vacancies on the luminescent properties has not been fully understood. In this article, impacts of point defects on the luminescence quantum efficiency of NBE emissions and on the intensity of deep emission bands will be described, based on the results of steady-state and time-resolved photoluminescence (TRPL) and positron annihilation measurements. The room temperature nonradiative lifetime (τNR) of the NBE excitonic photoluminescence (PL) peak in polar (0001) and (000-1) , nonpolar (11-20) and (10-10), and zincblende (001) GaN layers prepared by various growth techniques was shown to increase with the decrease in concentration or size of Ga vacancies (VGa) and with the decrease in gross concentration of point defects including complexes, leading to an increase in the NBE PL intensity. As the edge TD density decreased, the concentration or size of VGa tended to decrease and τNR tended to increase. However, there existed remarkable exceptions. The results indicate that the nonradiative recombination process is governed not by single point defects, but by certain defects introduced with the incorporation of VGa, such as VGa-defect complexes. Similar relations were found in AlxGa1-xN alloy films grown by metalorganic vapor phase epitaxy: i. e. τNR at room temperature increased with the decrease in the concentration of cation vacancies (VIII) and with the decrease in gross concentration of point defects. In addition to nonradiative processes, the VIII concentration was found to correlate with the intensity ratio of characteristic deep emission band to the NBE emission (Ideep/INBE). For example, Ideep/INBE at low temperature for the deep emission bands at 4.6, 3.8, and 3.1 eV of AlN epilayers grown by NH3-source molecular beam epitaxy had a linear correlation with the concentration or size of Al vacancies (VAl). Since the relative intensities of 3.1 eV and 3.8 eV bands increased remarkably with lowering the supply ratio of NH3 to Al (V/III ratio) and growth temperature (Tg), they were assigned to originate from VAl-O as well as VAl-shallow donor complexes. The VAl concentration could be decreased by adjusting the V/III ratio and Tg. In the case of AlxGa1-xN alloys, the concentration or size of VIII and Ideep/INBE at 300 K increased simultaneously with the increase in x up to approximately 0.7. Similar to the case for GaN and AlN, the deep emission band was assigned as being due to the emission involving VIII-O complexes.

High-harmonic generation in graphene heterostructures (2023)

Graphene has a large optical nonlinearity and supports electrically-tunable and long-lived plasmons. We present an experimental study of harmonic generation in graphene heterostructures, which enhance the nonlinearity and allow plasmons to mediate the non-linear response.
The Pseudomonas putida CsrA/RsmA homologues negatively affect c‐di‐GMP pools and biofilm formation through the GGDEF/EAL response regulator CfcR (2017)

Expression of cfcR, encoding the only GGDEF/EAL response regulator in Pseudomonas putida, is transcriptionally regulated by RpoS, ANR and FleQ, and the functionality of CfcR as a diguanylate cyclase requires the multisensor CHASE3/GAF hybrid histidine kinase named CfcA. Here an additional level of cfcR control, operating post-transcriptionally via the RNA-binding proteins RsmA, RsmE and RsmI, is unraveled. Specific binding of the three proteins to an Rsm-binding motif (5'CANGGANG3') encompassing the translational start codon of cfcR was confirmed. Although RsmA exhibited the highest binding affinity to the cfcR transcript, single deletions of rsmA, rsmE or rsmI caused minor derepression in CfcR translation compared to a ΔrsmIEA triple mutant. RsmA also showed a negative impact on c-di-GMP levels in a double mutant ΔrsmIE through the control of cfcR, which is responsible for most of the free c-di-GMP during stationary phase in static conditions. In addition, a CfcR-dependent c-di-GMP boost was observed during this stage in ΔrsmIEA confirming the negative effect of Rsm proteins on CfcR translation and explaining the increased biofilm formation in this mutant compared to the wild type. Overall, these results suggest that CfcR is a key player in biofilm formation regulation by the Rsm proteins in P. putida.
Distributed route selection for establishing real-time channels (2000)

To guarantee the delivery of real-time messages before their deadline, a real-time channel or connection must be established before the transmission of any message belonging to the connection. During this channel establishment phase, one must first select a route between the source and destination of this channel and then reserve sufficient resources along this route so that the worst-case end-to-end delay over the selected route may not exceed the user-specified delay bound. We propose an efficient distributed route selection scheme that is guaranteed to find a "qualified" route, if any, satisfying the performance requirement of the requested channel without compromising any of the existing guarantees. The proposed scheme can also eliminate the common reliability/performance bottleneck of a centralized route selection scheme while improving efficiency over the centralized and other distributed schemes. Although the proposed solution starts with searching all possible routes in parallel, it prunes infeasible routes quickly, and its worst-case operational overhead is shown to be only a linear function of the number of links in the network. Several examples and simulation results are presented to demonstrate the effectiveness of the proposed distributed route selection scheme as compared to sequential route-search schemes.
155-μm high-peak, high-average-power laser amplifier using an Er,Yb:glass planar waveguide for wind sensing coherent Doppler lidar (2019)

We have developed a high-gain, high-peak-power laser amplifier at an eye-safe 1.55 μm wavelength using an Er,Yb:glass planar waveguide for wind sensing coherent Doppler lidars (CDLs). Our planar waveguide is free from stimulated Brillouin scattering and realizes high gain thanks to its multi-bounce optical-path configuration. A peak power of 5.5 kW with a pulse energy of 3.2 mJ is achieved at the repetition frequency of 4 kHz, which leads to an average power of 12.8 W. The gain is more than 23 dB. The wind sensing at more than 30 km is demonstrated with a CDL using the developed amplifier.
Decentralized Control of Distributed Cloud Networks with Generalized Network Flows (2022)

Emerging distributed cloud architectures, e.g., fog and mobile edge computing, are playing an increasingly important role in the efficient delivery of real-time stream-processing applications (also referred to as augmented information services), such as industrial automation and metaverse experiences (e.g., extended reality, immersive gaming). While such applications require processed streams to be shared and simultaneously consumed by multiple users/devices, existing technologies lack efficient mechanisms to deal with their inherent multicast nature, leading to unnecessary traffic redundancy and network congestion. In this paper, we establish a unified framework for distributed cloud network control with generalized (mixed-cast) traffic flows that allows optimizing the distributed execution of the required packet processing, forwarding, and replication operations. We first characterize the enlarged multicast network stability region under the new control framework (with respect to its unicast counterpart). We then design a novel queuing system that allows scheduling data packets according to their current destination sets, and leverage Lyapunov drift-plus-penalty control theory to develop the first fully decentralized, throughput- and cost-optimal algorithm for multicast flow control. Numerical experiments validate analytical results and demonstrate the performance gain of the proposed design over existing network control policies.
Fe-doped Beta zeolite from organotemplate-free synthesis for NH3-SCR of NOx (2016)

Structure–performance correlations suggest that the content of isolated Fe<sup>3+</sup> in the Beta zeolite affects the SCR activity directly.
Microwave antenna for selective heating of glass melts (2012)

Glass processing is energy intensive, therefore the possibility to reduce energy consumption by selective energy intake into portions of glass using microwave heating is investigated. The paper describes how microwave radiation is guided into a limited volume of glass melt subjected to extrusion into a mold for forming. A parametric study is performed to establish the best geometry for the microwave antenna inside a plunger structure which is used industrially to feed glass melt into molds. Experimental proof and material issues are discussed.
Comparative Investigation of the Pharmacokinetics of Bosentan in Caucasian and Japanese Healthy Subjects (2004)

Bosentan is a dual endothelin receptor antagonist in development for the treatment of pulmonary arterial hypertension in Japan, whereas it is registered for this indication in Europe and the United States. The present study was conducted to compare the pharmacokinetics of bosentan in Caucasian and Japanese subjects. In a double-blind, placebo-controlled, ascending single-dose, 5-way crossover study, 10 healthy Caucasian and 10 Japanese subjects (1:1 male/female ratio) received single doses of 31.25, 62.5, 125, and 250 mg of bosentan or placebo. Pharmacokinetic profiles of bosentan and its pharmacologically active hydroxy metabolite, Ro 48-5033, were determined after each dose of bosentan. The pharmacokinetics of bosentan were similar and dose proportional in both ethnic groups. However, peak plasma concentration values of Ro 48-5033 were significantly greater in Japanese subjects (P < .05). This difference could not be explained by the lower body weight of the Japanese subjects. Females in both groups tended to have higher exposure to both bosentan and Ro 48-5033 than males. The results suggest that, based on pharmacokinetic grounds, no dose adjustment of bosentan is necessary when used to treat Japanese patients in comparison to Caucasian patients.
Data from Extracellular-Regulated Protein Kinase 5-Mediated Control of p21 Expression Promotes Macrophage Proliferation Associated with Tumor Growth and Metastasis (2023)

&lt;div&gt;Abstract&lt;p&gt;The presence of immunosuppressive macrophages that become activated in the tumor microenvironment constitutes a major factor responsible for tumor growth and malignancy. In line with this knowledge, we report here that macrophage proliferation is a significant feature of advanced stages of cancer. Moreover, we have found that a high proportion of proliferating macrophages in human tumors express ERK5. ERK5 was required for supporting the proliferation of macrophages in tumor grafts in mice. Furthermore, myeloid ERK5 deficiency negatively impacted the proliferation of both resident and infiltrated macrophages in metastatic lung nodules. ERK5 maintained the capacity of macrophages to proliferate by suppressing p21 expression to halt their differentiation program. Collectively, these data provide insight into the mechanism underpinning macrophage proliferation to support malignant tumor development, thereby strengthening the value of ERK5-targeted therapies to restore antitumor immunity through the blockade of protumorigenic macrophage activation.&lt;/p&gt;Significance:&lt;p&gt;These findings offer a new rationale for anti-ERK5 therapy to improve cancer patient outcomes by blocking the proliferative activity of tumor macrophages.&lt;/p&gt;&lt;/div&gt;
Giorgio Agamben, J. G. Farrell’sThe Singapore Grip, and the ColonialDispositif (2016)

In his Afterword to The Singapore Grip , J. G. Farrell thanks Giorgio and Ginevra Agamben for suggesting the phrase that became the title of his novel. What can we make of this surprising and unexpected connection between an Anglo-Irish author’s novel about colonial Singapore on the eve of its fall to the Japanese army during World War II and Agamben’s writings on biopolitics? Despite the serendipitous nature of the encounter between the two writers and the lack of any causal relation between their works, my paper argues that there is an unacknowledged affinity that allows us to open them up to what Agamben calls their Entwicklungsfähigkeit , “the locus and the moment wherein they are susceptible to development,” thereby bringing out the biopolitical elements in Farrell’s novel and turning Agamben’s insights into dispositifs or biopolitical apparatuses in the direction of the analysis of colonial rule.

Z-Pinning Approach for Reducing Mechanical Anisotropy of 3D Printed Parts (2024)

The mechanical strength of extrusion-based printed parts is often greatly reduced (25-50%) in the build direction (z-direction) compared to the in-plane strength due to poor bonding between successively deposited layers. This effect can be magnified (75-90% difference) when depositing fiber-reinforced materials or larger print areas with long layer times. Therefore, a patent-pending approach has been developed that deposits material into intentionally aligned voids in the zdirection, allowing continuous material to span multiple layers. The “z-pinning” approach can be applied to several concepts for improving the interlaminar strength of extrusion-based 3D printed parts as well as techniques for applying the technology across a broad spectrum of deposition platforms and material systems. Initial experimental results demonstrate a significant improvement (>3x) in mechanical strength and (>8x) toughness for fiber reinforced components.
Deferribacter autotrophicus sp. nov., an iron(III)-reducing bacterium from a deep-sea hydrothermal vent (2009)

A thermophilic, anaerobic, chemolithoautotrophic bacterium (designated strain SL50(T)) was isolated from a hydrothermal sample collected at the Mid-Atlantic Ridge from the deepest of the known World ocean hydrothermal fields, Ashadze field (1 degrees 58' 21'' N 4 degrees 51' 47'' W) at a depth of 4100 m. Cells of strain SL50(T) were motile, straight to bent rods with one polar flagellum, 0.5-0.6 mum in width and 3.0-3.5 mum in length. The temperature range for growth was 25-75 degrees C, with an optimum at 60 degrees C. The pH range for growth was 5.0-7.5, with an optimum at pH 6.5. Growth of strain SL50(T) was observed at NaCl concentrations ranging from 1.0 to 6.0 % (w/v) with an optimum at 2.5 % (w/v). The generation time under optimal growth conditions for strain SL50(T) was 60 min. Strain SL50(T) used molecular hydrogen, acetate, lactate, succinate, pyruvate and complex proteinaceous compounds as electron donors, and Fe(III), Mn(IV), nitrate or elemental sulfur as electron acceptors. The G+C content of the DNA of strain SL50(T) was 28.7 mol%. 16S rRNA gene sequence analysis revealed that the closest relative of strain SL50(T) was Deferribacter abyssi JR(T) (95.5 % similarity). On the basis of its physiological properties and phylogenetic analyses, the isolate is considered to represent a novel species, for which the name Deferribacter autotrophicus sp. nov. is proposed. The type strain is SL50(T) (=DSM 21529(T)=VKPM B-10097(T)). Deferribacter autotrophicus sp. nov. is the first described deep-sea bacterium capable of chemolithoautotrophic growth using molecular hydrogen as an electron donor and ferric iron as electron acceptor and CO(2) as the carbon source.
p‐Chloroamphetamine‐induced rat ejaculation is not associated with the preoptic nucleus or medial nucleus amygdala (2008)

<b>Aim: </b> In the rat, intraperitoneal injection of <i>p</i>-chloroamphetamine (PCA), which releases central 5-hydroxytryptamine (5-HT) from serotonergic nerve terminals, induces ejaculation, even in the absence of an estrus female or female-related smell information. It is well known that the medial preoptic nucleus (MPN) and the medial nucleus amygdala (MEA) play a major role in the control of male sexual behavior in mammals. We examined whether or not neuronal activity of the MPN and/or the MEA was associated with PCA-induced ejaculation. <b>Methods: </b> Using c-Fos immunohistochemistry, we demonstrated a difference in the neural activities of the MPN and the MEA for ejaculation during copulation with an estrus female and ejaculation by PCA injection. <b>Results: </b> Increased numbers of c-Fos-immunoreactive (c-Fos-IR) cells were found in the MPN and the MEA in the brains of the mating animals, whereas in the brains of the animals undergoing PCA-induced ejaculation there was no increase in the number of c-Fos-IR cells in the MPN and a small increase in the MEA. <b>Conclusion: </b> Based on these results, ejaculation induced by PCA is not associated with the MPN. Moreover, the MEA is not the main act for this ejaculation. (Reprod Med Biol 2008; <b>7</b>: 37-43).
Scalable Graph Theory Approach for Electric Aircraft Power System Optimization (2019)

This work proposes an approach to optimize the power system configuration in electric aircrafts. The proposed approach, intended to be used as an early stage design tool, includes the utilization of mathematical methods such as graph theory to identify optimal solutions with regard to the number of components as well as interconnection and placement within the power system. Subsystems and components are represented as nodes, and properties such as power and energy density, efficiency, and capacity are assigned to them. Aircraft power system optimization is a non-linear multi-objective problem and stochastic techniques may be required for its solution. Such techniques often require a large number of possible candidate power system configurations, which would be facilitated by the proposed network graph approach. Objectives include total system mass, efficiency, reliability, and a composite cost function, which is a weighted combination of these, can be formulated.

Novel Gap Filling BARC with High Chemical Resistance (2019)

In state-of-the-art semiconductor manufacturing processes, a BARC film/process needs to meet a multitude of requirements. In particular, it should possess a good SC-1(mixture of NH <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> /H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) resistance, because a BARC film often serves as a wet etching mask. By introducing a low molecular weight additive which has a higher adhesive strength to the TiN surface than that of a conventional BARC, we have developed a novel BARC that possesses a better gap filling property, a superior planarity, and an over 3 times higher SC-1 resistance.
The interactive contents authoring system for terrestrial digital multimedia broadcasting (2007)

This paper introduces an interactive contents authoring system which can easily and conveniently produce interactive contents for the Terrestrial Digital Multimedia Broadcasting (T-DMB). For interactive broadcasting service, T-DMB adopted MPEG-4 Systems technology. In order to the interactive service becomes flourishing on the market, various types of interactive contents should be well provided prior to the service. In MPEG-4 Systems specification, broadcasting contents are described by the combination of a large number of nodes, routes and descriptors. In order to provide interactive data services through the T-DMB network, it is essential to have an interactive contents authoring system which allows contents authors to compose interactive contents easily and conveniently even if they lack any background on MPEG-4 Systems technology. The introduced authoring system provides powerful graphical user interface and produces interactive broadcasting contents in the forms of binary and textual format. Therefore, the interactive contents authoring system presented in this paper would vastly contribute to the flourishing interactive service.
Modelling of thermal vias in thin film multichip modules (2002)

A semi-analytical model is presented for evaluating the thermal resistance of via networks used in thin film multichip modules. Correlations between dimensionless groups were derived from numerical data. Therefore, the via network was divided in three basic elements. This allows one to reconstruct the network as a series and parallel connection. The results of this semi-analytical model are compared with those of an existing analytical model and a 3D finite element model. Good agreement between the three models was obtained. The heat conduction efficiency of a staggered thermal via network is defined and the influence of several parameters was investigated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
