Emergent behavior based on disparity of individual capability (2007)

We present the result of our research on the emergent behavior of heterogeneous agents in Multi-Agent System (MAS). We extended the commonly considered MAS for the predator prey problem (PPP), initially comprising homogeneous predator agents into heterogeneous MAS featuring predator agents with diverse sensory and moving abilities. Moreover, we evolved, via genetic programming, the behavior of these agents, and discovered the emergence of a characteristic behavior that is (i) unique to the heterogeneous systems, (ii) well specialized to fit the individual morphological features of the agents, and (iii) more efficient than that of the homogeneous agents.
Effects of resonant LO phonon assisted excitation on the photoluminescence spectra of InGaN/GaN quantum wells (2008)

Abstract We have observed oscillations in the low temperature (T &lt; 50 K) photoluminescence excitation spectra of an InGaN/GaN single quantum well at photon energies above the GaN bandgap. We attribute the features in the spectra to excitation of electrons at multiples of the LO phonon energy above the GaN conduction band edge. The rapid cooling of these electrons to the GaN conduction band edge and their subsequent capture leads to a shift, in the photoluminescence spectrum and hence the oscillations in photoluminescence. We interpret the shift in the spectrum as being due to a modification of the occupation of the distribution of localization centres by electrons. (© 2008 WILEY‐VCH Verlag GmbH &amp; Co.

Cerebrospinal Fluid Biomarkers Mirror Rate of Cognitive Decline (2013)

The ability to predict future decline in cognitive systems using the cerebrospinal fluid (CSF) biomarkers 42 amino acid form of amyloid-β (Aβ42) and total tau (T-tau) is not fully understood. In a clinical sample ranging from cognitively healthy to dementia (n = 326), linear regression models were performed in order to investigate the ability of CSF biomarkers to predict cognitive decline in all cognitive domains from baseline to 2-year follow-up. Gender, age, and years of education were included as covariates. In patients with subjective cognitive impairment, T-tau had a small impact on executive functions (r2 = 0.07). T-tau had a small to moderate influence (r2 = 0.06-0.11) on all cognitive functions with the exception of visuospatial functions in patients with mild cognitive impairment (MCI). In patients with dementia, the impact of T-tau was large (r2 = 0.29) on semantic memory. Aβ42 had a small effect (r2 = 0.07) on speed and executive functions in MCI. In patients with dementia, Aβ42 had a moderate influence (r2 = 0.13-0.24) on semantic and verbal working memory/fluency. Our results speak in favor of the notion that CSF biomarkers reflect the rate of cognitive decline across the continuum of cognitive impairment from healthy to dementia. CSF predicted subsequent decline in more cognitive domains among MCI cases, but the impact was most pronounced in patients with dementia.
DSP-based architectures for mobile communications: past, present and future (2000)

Programmable DSPs are pervasive in the wireless handset market for digital cellular telephony. We present the argument that DSPs will continue to play a dominant, and in fact increasing, role in wireless communications devices by looking at the history of DSP use in digital telephony, examining the DSP-based solution options for today's standards, and looking at future trends in low-power DSPs.
Cell Culture Technology—An Overview (2005)

The last three decades have witnessed a major development in cell culture technology. The ﬁeld developed substantially and became an essential part of biotechnology (1). During its evolution, cell culture technology successfully integrated various disciplines, including cell biology, genetic engineering, protein chemistry, genomics, and chemical engineering. Cell culture technology is now the established method of producing a number of important proteins, especially those that are large, complex, and glycosylated (2).
Relative stability of some possible phases of graphitic carbon nitride (1999)

Various graphitic phases of ${\mathrm{C}}_{3}{\mathrm{N}}_{4}$ are examined using the local-density approximation plane-wave-pseudopotential approach. These are three forms of p graphite and the $P6\ifmmode\bar\else\textasciimacron\fi{}m2$ graphite structure. Each differs only in planar stacking and character of planar C-N bonds. Two forms of p graphite are predicted to be stable with energies very close to the $P6\ifmmode\bar\else\textasciimacron\fi{}m2$ structure. This suggests a strong phase instability of the graphite structures and material softening along the c axis.
Layer-4 service differentiation and resource isolation (2003)

While the differentiated services (DiftServ) infrastructure is scalable and robust in providing network quality of service (QoS), there are serious drawbacks with the services provided by DiffServ: (1) the services are coarse-grained and one-way only; (2) no service differentiation and resource isolation are provided to meta-data packets such as TCP SYN and ACK packets. Moreover the coarse-grained service differentiation and the lack of resource isolation at IP routers exposes its vulnerability to distributed denial of service (DDoS) attacks. Based on the concept of layer-4 service differentiation and resource isolation, where the transport-layer information is inferred from the IP headers and used for packet classification and resource management, we present a scalable fine-grained DiffServ (sf-DiffServ) architecture that provides fine-grained service differentiation and resource isolation among thinner behavior aggregates (BAs). The sf-DiffServ architecture consists of a fine-grained QoS classifier and an adaptive weight-based resource manager at IP routers. A two-stage packet classification mechanism is devised to decouple the fine-grained QoS lookup from the routing lookup at core routers. Due to its scalable QoS support for TCP control segments, sf-DiffServ supports bi-directional differentiated services for TCP sessions. Most importantly, the fine-grained resource isolation provided inside the sf-DiffServ is a powerful built-in protection mechanism to counter DDoS attacks, reducing the vulnerability of the Internet to DDoS attacks.
Transport of perfluorocarbon tracers in the Cranfield Geological Carbon Sequestration Project (2018)

Abstract A field‐scale carbon dioxide (CO 2 ) injection pilot project was conducted by the Southeast Regional Carbon Sequestration Partnership (SECARB) at Cranfield, Mississippi. Two associated campaigns in 2009 and 2010 were carried out to co‐inject perfluorocarbon tracers (PFTs) and sulfur hexafluoride (SF 6 ) with CO 2 . Tracers in gas samples from two observation wells were analyzed to construct breakthrough curves. In this work, we present the field data and numerical modeling of the flow and transport of CO 2 , brine, and tracers. A high‐resolution static model of the formation geology in the detailed area study (DAS) was used to capture the impact of connected flow pathways created by fluvial channels on breakthrough curves and breakthrough times of PFTs and SF 6 tracers. We use the cubic‐plus‐association (CPA) equation of state, which takes into account the polar nature of water molecules, to describe the phase behavior of CO 2 –brine‐tracer mixtures. Our simulated results show good agreement for the 2009 tracer campaign in Cranfield, while a larger discrepancy emerges by 2010. The combination of multiple tracer injection pulses with detailed numerical simulations proves to be a powerful tool in constraining both formation properties and how complex flow paths develop over time. © 2018 Society of Chemical Industry and John Wiley &amp; Sons, Ltd.
Highly scalable video coding by bidirectional predict-update 3-band schemes (2004)

Motion-compensated temporal filtering is an essential ingredient of recently developed wavelet-based scalable video coding schemes. The lifting implementation of these decompositions represents a versatile tool for spatio-temporal optimizations and numerous improvements have thus been proposed. An additional feature has been introduced lately by providing a 3-band lifting temporal decomposition, allowing non-dyadic scalability factors. The paper presents a motion-compensated scheme which is the 3-band equivalent of the 5/3 temporal filterbank. The proposed structure does not enter the classical lifting framework and therefore its invertibility is studied. Simulation results show higher coding efficiency, improved visual quality and more flexibility compared to the previously introduced Haar-like 2 or 3-band schemes.
Gridded Square-Ring Frequency Selective Surface for Angular-Stable Response on Chipless Indoor Location Tag Landmarks (2021)

This paper studies the use of gridded square-ring FSSs to encode the backscattered response of trihedral corner reflectors, acting as passive landmarks in a mm-wave indoor self localization system. Previous tags presented low resonance stability under oblique incidence of the incoming wave, which limits the system performance under real operating conditions. The designed FSS uses a miniaturized unit cell to minimize phase differences between its elements, which are responsible for the fluctuating resonance response. The smaller these phase differences, the less varies the response. The new design presents a more stable response than a previous work at W-band (65-110 GHz), at the cost of lower frequency selectivity and range. But, the operating angular region of the tag is ±35°, which allows to encode 45 notches, which means 5.5 bits, under transverse magnetic planar wave excitation for identification of tags in indoor self-localizing applications.
Point-contact studies of current-controlled domain switching in magnetic multilayers (2000)

We present measurements demonstrating current-induced magnetic domain switching, and also other magnetic excitations, in point-contact devices containing alternating ferromagnetic (F) and noble metal (N) layers, for perpendicular currents ∼109 A/cm2. For F/N/F trilayers in which one F layer is much thinner than the other, we can controllably switch the magnetic moments in the two F layers parallel with a current bias of one sign, and switch them antiparallel with a reversed current. For thicker magnetic films, and for thin films in the presence of a saturating magnetic field, we observe nonhysteretic current-induced changes in resistance, which can be understood as current-induced spin-wave excitations. These observations are in agreement with a model of current-induced magnetic reorientations caused by local exchange forces between conduction electrons and the magnetic moments.
Formation of the first phase in sputter-deposited Nb/Al multilayer thin films (1998)

Abstract The reaction of sputter-deposited Nb/Al multilayer thin films with periodicities in the range 10—500nm has been studied by X-ray and electron diffraction, transmission electron microscopy and differential scanning calorimetry. The first phase to form upon annealing the films is found to be NbAl3, independent of multilayer periodicity and overall composition. Constant-heating-rate calorimetry measurements show the presence of two exothermic peaks for the formation of this phase, while isothermal scans show that the first peak is associated with a nucleation-and-growth-type transformation. The formation of the trialuminide is thus interpreted as a two-stage process of nucleation and growth to coalescence (first peak) followed by growth until the consumption of one or both reactants (second peak). Although both the identity of the first phase and the two-stage nature of its formation are in agreement with previous studies in evaporated Nb/Al films, the activation energy for stage 2 and the peak temperatures for the two stages (at a given heting rate and a given Al layer thickness) are found to be higher in the sputter-deposited films. Transmission electron microscopy studies of a partially reacted sputter-deposited Nb/Al film reveals that the growth of NbAl3 occurs along the Nb—Al interfaces as well as along some Al grain boundaries. The latter growth geometry not only highlights the role of reactant grain structure in thin film reactions but also indicates that Nb diffusion into Al grain boundaries, rather than Al into Nb, is the rate-controlling mechanism during these early stages of the reaction.
Analytical Models for Distribution of the Envelope and Phase of Linearly Modulated Signals in AWGN Channel (2014)

Abstract In this paper, analytical expressions for the distribution of the envelope and phase of linearly modulated signals such as BPSK,M-PSK, andM-QAM in AWGN are presented.We perform numerical simulations for different orders of signal constellations. The results show that the proposed theoretical models are in excellent agreement with the estimated distributions from various numerical experiments.
A comparison study between a resonant filter and an adaptive feed-forward cancellation for implementation of a control system (2014)

In this paper, we present a comparison study between a resonant filter and an adaptive feed-forward cancellation (AFC). To compensate for disturbances, the resonant filter decreases the gain of the sensitivity function by using the vector locus. The adaptive learning method adjusts the coefficients of the AFC to compensate for a disturbance. Each method does not make difference with respect to performance for disturbance compensation. However, important factors for constructing the control system should be also considered to implement for a control systems in addition to the performance. This paper introduces comparison study between the resonant filter and the AFC for implementation of a control system. The simulations of the disturbance compensation were conducted using an HDD Benchmark Problem as a case study. Engineers can decide which control theory is better to be implemented in the control system with reference to this study.
Letter by Montani et al Regarding Article, “Elevated Levels of Inflammatory Cytokines Predict Survival in Idiopathic and Familial Pulmonary Arterial Hypertension” (2011)

We read with great interest the article by Soon et al, 1 in which they demonstrated the importance of dysregulation in inflammatory mediators by conducting a large screening of cytokines in idiopathic and heritable pulmonary arterial hypertension (PAH). These results confirm preliminary data on serum levels of interleukin-1 and interleukin-6 and emphasize the conclusions of the world conference on pulmonary hypertension. 2,3 However, the authors' conclusion that cytokine levels impact patient survival seems to overstate their results, and deserves further discussion.
On limitations of using cloud storage for data replication (2012)

Cloud storage services often provide a key-value store (KVS) functionality, an object-based interface for accessing a collection of unstructured data items or blobs. Every blob is associated with a key that serves as identifier to access the blob. In the simplest form, a key-value store provides only methods for writing and reading an entire blob, for removing blobs, and for listing all defined keys. On the other hand, many existing schemes for replicating data with the goal of enhancing resilience (e.g., based on quorum systems) associate logical timestamps with the stored values, in order to distinguish multiple versions of the same data item. This paper uses the consensus number of a shared storage abstraction as a measure for its power to facilitate the implementation of data replication. It is demonstrated that a KVS is a very simple primitive, not different from read/write registers in this sense, and that a replica capable of the typical operations on timestamped data is fundamentally more powerful than a KVS. Hence, data replication schemes over storage providers with a KVS interface are inherently more difficult to realize than replication schemes over providers with richer interfaces.

Microbial Metabolism Part 9. Structure and Antioxidant Significance of the Metabolites of 5,7-Dihydroxyflavone (Chrysin), and 5- and 6-Hydroxyflavones (2008)

5,7-Dihydroxyflavone (chrysin) (1) when fermented with fungal cultures, Aspergillus alliaceous (ATCC 10060), Beauveria bassiana (ATCC 13144) and Absidia glauco (ATCC 22752) gave mainly 4'-hydroxychrysin (4), chrysin 7-O-beta-D-4-O-methylglucopyranoside (5) and chrysin 7-sulfate (6), respectively. Mucore ramannianus (ATCC 9628), however, transformed chrysin into six metabolites: 4'-hydroxy-3'-methoxychrysin (chrysoeriol) (7), 4'-hydroxychrysin (apigenin) (4) 3',4'-dihydroxychrysin (luteolin) (8), 3'-methoxychrysin 4'-O-alpha-D-6-deoxyallopyranoside (9), chrysin 4'-O-alpha-D-6-deoxyallopyranoside (10), and luteolin 3'-sulfate (11). Cultures of A. alliaceous (ATCC 10060) and B. bassiana (ATCC 13144) metabolized 5-hydroxyflavone (2) into 5,4'-dihydroxyflavone (12) and 4'-hydroxyflavone 5-O-beta-D-4-O-methylglucopyranoside (13), respectively. 6-Hydroxyflavone (3) was transformed into 6-hydroxyflavanone (14), flavone 3-O-beta-D-4-O-methylglucopyranoside (15) and (+/-)-flavanone 6-O-beta-D-4-O-methylglucopyranoside (16) by cultures of Beauveria bassiana (ATCC 13144). The structures of the metabolic products were elucidated by means of spectroscopic data. The significance of the metabolites as antioxidants in relation to their structure is briefly discussed.
Identification of monoclonal antibodies that inhibit the function of protein C inhibitor. Evidence for heparin-independent inhibition of activated protein C in plasma (1988)

Monoclonal antibodies specific for protein C inhibitor (PCI) partially blocked the inactivation of activated protein C (APC) in plasma, whereas in a purified system, the PCI activity could be completely blocked. The inactivation of APC in normal and in PCI-depleted plasma was similar in the absence of heparin. The addition of heparin did not change the rate of inactivation of APC in PCI-depleted plasma, whereas in normal plasma a rapid phase of inhibition of APC was followed by a slower phase of inhibition. The slower phase was identical to the rate of inhibition of APC in the absence of heparin. After incubation of normal plasma with a monoclonal antibody specific for PCI that blocked its activity, there was no difference in heparin-dependent or heparin- independent inhibition of APC. These results indicate that in the absence of heparin PCI is unable to inactivate APC in a plasma environment.
ABC transporters in antibiotic-producing actinomycetes (1998)

Work in the authors laboratory was supported by grants of the Spanish Ministry of Education and Science through CICYT (PB94-1319) and Plan Nacional en Biotecnologia (BIO91-0758 and BIO94-0037) and from the European Union (BIOTECH programme, PL930145).
Screening for latent TB, HIV, and hepatitis B/C in new migrants in a high prevalence area of London, UK: a cross-sectional study (2014)

The one-stop approach was feasible in this context and acceptability was high. However, the number of presenting migrants was surprisingly low, reflecting the barriers to care that this group face on arrival, and none ultimately received treatment. The ongoing UK debate around immigration checks and charging in primary care for new migrants can only have negative implications for the promotion of screening in this group. Until GP registration is more actively promoted in new migrants, a better place to test this one-stop approach could be in A&E departments where migrants may present in larger numbers.
Quantitative analysis of Doppler spectrum modifications yielded by contrast agents insonified at high pressure (1999)

In this report, the authors consider the modifications yielded in the Doppler spectrum when acoustic fields of increasing intensities are applied to encapsulated gas bubbles. Their in vitro experimental results show that the spectrum bandwidth is nearly proportional to the incident acoustic pressure, when its amplitude is maintained below about 200 kPa. At higher pressure levels, it even may happen that, in a steady, unidirectional flow (which should generate only positive Doppler frequencies), the Doppler spectrum is enlarged up to the point that negative Doppler shifts also are produced. Possible explanations in terms of either radiation force or streaming are discussed for this asymmetrical bandwidth enlargement.
A High Power RF Power Supply for High Energy Physics Applications (2006)

This paper considers the design of a “long-pulse” modulator supply rated at 25kV, 10A (250kW peak power, duty ratio 10%, 25kW average power, pulse length ≃ 1 – 2ms). The supply is based on direct modulation of a multi-phase resonant power supply, fed by an active rectifier. The objectives of the development are to produce a compact power supply, with low stored energy and with high power quality at the utility supply. The paper provides a brief overview of the technology, followed by a discussion of the design choices.
