Suspicion scoring of networked entities based on guilt-by-association, collective inference, and focused data access 1 (2005)

We describe a guilt-by-association system that can be used to rank networked entities by their suspiciousness. We demonstrate the algorithm on a suite of data sets generated by a terrorist-world simulator developed to support a DoD program. Each data set consists of thousands of entities and some known links between them. The system ranks truly malicious entities highly, even if only relatively few are known to be malicious ex ante. When used as a tool for identifying promising data-gathering opportunities, the system focuses on gathering more information about the most suspicious entities and thereby increases the density of linkage in appropriate parts of the network. We assess performance under conditions of noisy prior knowledge of maliciousness. Although the levels of performance reported here would not support direct action on all data sets, the results do recommend the consideration of network-scoring techniques as a new source of evidence for decision making. For example, the system can operate on networks far larger and more complex than could be processed by a human analyst. This is a follow-up study to a prior paper; although there is a considerable amount of overlap, here we focus on more data sets and improve the evaluation by identifying entities with high scores simply as an artifact of the data acquisition process.

Diamine bis(phenolate) and pendant amine bis(phenolate) ligands: catalytic activity for the room temperature palladium‐catalyzed Suzuki–Miyauracoupling reaction (2015)

A series of amine bis(phenolate) ligands bearing aryl substituents of varying steric bulk are reported and characterized using single‐crystal X‐ray diffraction, NMR spectroscopy and high‐resolution mass spectrometry experiments. Palladium complexes derived in situ from these ligands are evaluated as catalysts for the Suzuki–Miyaura coupling of phenylboronic acid and aryl bromides. High conversions are observed for these reactions in methanol solvent at low catalyst loadings (0.01 mol%), short reaction times (30 min) and mild temperatures (30°C). Conversion is observed for a range of substrates, and is found to depend on the nature of the external base and solvent employed. These findings demonstrate the utility of catalysts derived from late transition metal complexes of amine bis(phenolate) ligands, particularly those bearing bulky cumyl substituents.

Optimal irrigation of cotton in northern Greece using AquaCrop: a multi-year simulation study (2015)

A hybrid approach for optimizing irrigation was developed and tested via simulation of cotton cultivation in Northern Greece. At any given day during the season, the remaining cultivation days were conceptually split into two parts: the five coming days and the rest of the season. Accurate weather forecasts were assumed to be available for the first period, during which only one irrigation event could take place. For the second period, average historical weather data were used as long-term forecasts, and rather than optimizing directly the irrigation events, the decision variables corresponded to a number of soil water levels at which irrigation would be triggered and the corresponding irrigation amounts. This hybrid approach ensured that the number of decision variables remained acceptably small so that the procedure can be computed repeatedly in real time during the season.
High-yield bottom-up synthesis of 2D metal–organic frameworks and their derived ultrathin carbon nanosheets for energy storage (2017)

We report a facile and low-cost bottom-up synthesis of ultrathin Zn(bim)(OAc) MOF nanosheets (with thicknesses of ∼5 nm and a high yield of ∼65%) and their derived N-doped porous ultrathin (2.5 ± 0.8 nm) carbon nanosheets (UT-CNSs) for energy storage.
Mechanochemical approach towards multi-functionalized 1,2,3-triazoles and anti-seizure drug Rufinamide analogs using copper beads (2022)

Highly regiospecific, copper salts-free and neat conditions have been demonstrated for the 1,3-dipolar Azide-Alkyne Cycloaddition (AAC) reactions under mechanochemical conditions. A group of structurally challenging alkynes and heterocyclic derivatives was efficiently implemented to achieve highly functionalized 1,4-disubstituted-1,2,3-triazoles in good to excellent yield by using the Cu beads without generation of unwanted byproducts. Furthermore, high-speed ball milling (HSBM) strategy has also been extended to the synthesis of commercially available pharmaceutical agent, Rufinamide, an antiepileptic drug (AED) and its analogues. The same strategy was also applied for the synthesis of Cl-derivative of Rufinamide. Analysis of the single crystal XRD data of the triazole was also performed for the final structural confirmation. The Cu beads can be easily recoverable from the reaction mixture and used for the further reactions without any special treatment.
Performance study of MAC for service differentiation in IEEE 802.11 (2003)

In a wireless local area network (WLAN), medium access control (MAC) layer access parameters are usually differentiated for various classes of users to provide different quality of service (QoS). In particular, in this paper, we investigate the MAC layer performance of IEEE 802.11e based WLAN, where the traffic flows are classified and each class is assigned different MAC parameters, such as inter-frame space (IFS), and contention window (CW) size. These parameters play a critical role in determining the system performance. Thus, an appropriate mathematical model is desired to determine the QoS differentiation on these parameters and guide the system design. However, so far, little work was reported. We propose a novel model based on the Markov chain, which takes into account almost all the important MAC parameters, CW, IFS, class number, etc. Despite its simplicity, it is demonstrated that our proposed model agrees quite well with the results obtained with the time-consuming simulations.
Emergence and Rearrangement of Dynamic Supramolecular Aggregates Visualized by Interferometric Scattering Microscopy (2020)

Studying dynamic self-assembling systems in their native environment is essential for understanding the mechanisms of self-assembly and thereby exerting full control over these processes. Traditional ensemble-based analysis methods often struggle to reveal critical features of the self-assembly that occur at the single particle level. Here, we describe a label-free single-particle assay to visualize real-time self-assembly in aqueous solutions by interferometric scattering microscopy. We demonstrate how the assay can be applied to biphasic reactions yielding micellar or vesicular aggregates, detecting the onset of aggregate formation, quantifying the kinetics at the single particle level, and distinguishing sigmoidal and exponential growth of aggregate populations. Furthermore, we can follow the evolution in aggregate size in real time, visualizing the nucleation stages of the self-assembly processes and record phenomena such as incorporation of oily components into the micelle or vesicle lumen.
The many faces of publish/subscribe (2003)

Well adapted to the loosely coupled nature of distributed interaction in large-scale applications, the publish/subscribe communication paradigm has recently received increasing attention. With systems based on the publish/subscribe interaction scheme, subscribers register their interest in an event, or a pattern of events, and are subsequently asynchronously notified of events generated by publishers. Many variants of the paradigm have recently been proposed, each variant being specifically adapted to some given application or network model. This paper factors out the common denominator underlying these variants: full decoupling of the communicating entities in time, space, and synchronization. We use these three decoupling dimensions to better identify commonalities and divergences with traditional interaction paradigms. The many variations on the theme of publish/subscribe are classified and synthesized. In particular, their respective benefits and shortcomings are discussed both in terms of interfaces and implementations.
Automatic quantification of neurite outgrowth by means of image analysis (2004)

A system for quantification of neurite outgrowth in in-vitro experiments is described. The system is developed for routine use in a high-throughput setting and is therefore needs fast, cheap, and robust. It relies on automated digital microscopical imaging of microtiter plates. Image analysis is applied to extract features for characterisation of neurite outgrowth. The system is tested in a dose-response experiment on PC12 cells + Taxol. The performance of the system and its ability to measure changes on neuronal morphology is studied.
Aiming for the Sweet Spot: Glyco-Immune Checkpoints and γδ T Cells in Targeted Immunotherapy (2020)

Though a healthy immune system is capable of recognizing and eliminating emergent cancerous cells, an established tumor is adept at escaping immune surveillance. Altered and tumor-specific expression of immunosuppressive cell surface carbohydrates, also termed the "tumor glycocode," is a prominent mechanism by which tumors can escape anti-tumor immunity. Given their persistent and homogeneous expression, tumor-associated glycans are promising targets to be exploited as biomarkers and therapeutic targets. However, the exploitation of these glycans has been a challenge due to their low immunogenicity, immunosuppressive properties, and the inefficient presentation of glycolipids in a conventional major histocompatibility complex (MHC)-restricted manner. Despite this, a subset of T-cells expressing the gamma and delta chains of the T-cell receptor (γδ T cells) exist with a capacity for MHC-unrestricted antigen recognition and potent inherent anti-tumor properties. In this review, we discuss the role of tumor-associated glycans in anti-tumor immunity, with an emphasis on the potential of γδ T cells to target the tumor glycocode. Understanding the many facets of this interaction holds the potential to unlock new ways to use both tumor-associated glycans and γδ T cells in novel therapeutic interventions.
Blockchain for aircraft spare part management: Evaluating the robustness of the Maintenance, Repair and Overhaul business model (2018)

Due to the complexity of aircraft spare part management, the aviation supply chain and ecosystem are not deemed as transparent as desired. As a result, participants face additional cost of communication and compliancy as proprietary component data is not made immediately accessible. To solve these problems, Maintenance, Repair and Overhaul (MRO) providers currently consider to use Blockchain to track and trace aircraft spare parts. Guided by Business Model Stress Test, this thesis evaluates the robustness of MRO business models when they use Blockchain as an aircraft spare part track and trace capability. Blockchain as an aircraft spare part track and capability is not only strategically relevant for cost-conscious innovating MROs, it also does not impose a risk to the robustness of their business model in most scenarios. MROs should engage in a regulatory-backed Blockchain consortium through which they share limited component data throughout the entire industry. If this is not possible, they can retreat from the consortium under the notion that their business model is threatened. Even though Blockchain could improve aviation supply chain and ecosystem transparency, the feasibility of the consortium is questionable. To remedy this concern, future research should focus on identifying strategic incentives for Original Equipment Manufacturers and aircraft operators to participate in the Blockchain consortium.

[Right atrial flutter or tachycardia?]. (2008)

We present a case of 67-year-old patient with recurrent persistent atrial macroreentry after surgical removal of left atrial myxoma. The macroreentry was cavo-tricuspid isthmus dependent with a pseudo-atypical atrial flutter morphology and variable cycle lengths between 290 and 340 ms.
Herpes Simplex Virus 1 Protein Kinase Us3 and Major Tegument Protein UL47 Reciprocally Regulate Their Subcellular Localization in Infected Cells (2011)

Us3 is a serine-threonine protein kinase encoded by herpes simplex virus 1 (HSV-1). We have identified UL47, a major virion protein, as a novel physiological substrate of Us3. In vitro kinase assays and systematic analysis of mutations at putative Us3 phosphorylation sites near the nuclear localization signal of UL47 showed that serine at residue 77 (Ser-77) was required for Us3 phosphorylation of UL47. Replacement of UL47 Ser-77 by alanine produced aberrant accumulation of UL47 at the nuclear rim and impaired the nuclear localization of UL47 in a significant fraction of infected cells. The same defect in UL47 localization was produced by an amino acid substitution in Us3 that inactivated its protein kinase activity. In contrast, a phosphomimetic mutation at UL47 Ser-77 restored wild-type nuclear localization. The UL47 S77A mutation also reduced viral replication in the mouse cornea and the development of herpes stromal keratitis in mice. In addition, UL47 formed a stable complex with Us3 in infected cells, and nuclear localization of Us3 was significantly impaired in the absence of UL47. These results suggested that Us3 phosphorylation of UL47 Ser-77 promoted the nuclear localization of UL47 in cell cultures and played a critical role in viral replication and pathogenesis in vivo. Furthermore, UL47 appeared to be required for efficient nuclear localization of Us3 in infected cells. Therefore, Us3 protein kinase and its substrate UL47 demonstrated a unique regulatory feature in that they reciprocally regulated their subcellular localization in infected cells.
Light-weight stream synchronization framework for multimedia collaborative applications (2002)

Today's Internet best-effort services introduce unavoidable uncertainties in the data transfer delay and create the need for synchronization mechanisms that preserve the temporal relationship among streams of distributed multimedia applications. We present algorithms for stream synchronization that are immune to moderate clock skew between sender and receivers and take into account the different time constraints of each media. In our time model, we introduce the idea of a virtual observer, which perceives the session as being in the same room with a sender. We propose policies for delay management and special consideration is given to the time the algorithms take to reach steady state. We avoid the need for globally synchronized clocks for media synchronization by introducing the concept of user's multimedia presence, which defines a new manner for combining streams coming from multiple sites. Finally, we evaluate this framework with traces collected from the Internet.
An Electrokinetic Instability Micromixer (2001)

Abstract We present the design, fabrication, and characterization of a micromixer that uses an electrokinetic instability (EKI) as the stirring mechanism. We have observed that microchannel liquid flows subjected to sinusoidally alternating electric fields exhibit, under certain electric field strengths and geometries, a flow instability capable of rapidly stirring micro- and nanoliter volume solutions [1]. We have performed a fluorescein dilution experiment to observe the rapid dispersion of dyed and undyed buffers within the mixing chamber as a result of EKI stirring. The flow field was imaged using an inverted, epifluorescent microscope fitted with a 12 bit, cooled CCD camera. We have initially characterized the mixer performance by computing ensemble-averaged probability density functions (PDF’s) and power spectra of the instantaneous, spatial fluorescence intensity fields. This novel stirring mechanism has the potential for significantly improving the functionality of microfluidic, bioanalytical devices.
A supramolecular biomimetic skin combining a wide spectrum of mechanical properties and multiple sensory capabilities (2018)

Biomimetic skin-like materials, capable of adapting shapes to variable environments and sensing external stimuli, are of great significance in a wide range of applications, including artificial intelligence, soft robotics, and smart wearable devices. However, such highly sophisticated intelligence has been mainly found in natural creatures while rarely realized in artificial materials. Herein, we fabricate a type of biomimetic iontronics to imitate natural skins using supramolecular polyelectrolyte hydrogels. The dynamic viscoelastic networks provide the biomimetic skin with a wide spectrum of mechanical properties, including flexible reconfiguration ability, robust elasticity, extremely large stretchability, autonomous self-healability, and recyclability. Meanwhile, polyelectrolytes' ionic conductivity allows multiple sensory capabilities toward temperature, strain, and stress. This work provides not only insights into dynamic interactions and sensing mechanism of supramolecular iontronics, but may also promote the development of biomimetic skins with sophisticated intelligence similar to natural skins.
Evaluation of NO Oxidation Properties over a Mn-Ce/γ-Al2O3Catalyst (2016)

With the purpose of studying the effect of diesel oxidation catalyst (DOC) on the NO oxidation activity, a series of<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:mi>x</mml:mi></mml:mrow></mml:math>Mn10Ce/<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M2"><mml:mrow><mml:mi>γ</mml:mi></mml:mrow></mml:math>-Al 2 O 3 (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M3"><mml:mrow><mml:mi>x</mml:mi></mml:mrow></mml:math>= 4, 6, 8, and 10) catalysts were synthesized by acid-aided sol-gel method. The physicochemical properties of the catalysts were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and Transmission Electron Microscope (TEM). Result showed that the crystalline size of MnO x and CeO 2 ranges from 5 nm to 30 nm and manganese existed mainly in the catalysts in the form of manganese dioxide. Moreover, NO oxidation experiments were carried out to evaluate the activity of the catalysts; according to the results, 6Mn10Ce/ γ -Al 2 O 3 catalyst showed the supreme NO oxidation activity with a NO to NO 2 conversion rate of 83.5% at 300°C. Compared to 500 ppm NO inlet concentration, the NO conversion was higher than that of 750 and 1000 ppm NO over 6Mn10Ce/ γ -Al 2 O 3 catalyst in the temperature range of 150–300°C.
Dual-Band Counter Circularly Polarized Radiation From a Single-Arm Metamaterial-Based Spiral Antenna (2013)

A single-arm spiral antenna whose arm is made of a metamaterial (MTM) transmission line having right- and left- handed properties is discussed. This antenna, abbreviated as the 1-MTM-SPA, has an extremely low-profile structure (0.016 wavelength at a balanced frequency of 3 GHz) and does not need a balun circuit. It is predicted that the 1-MTM-SPA will operate as a circularly polarized (CP) antenna, where right-handed CP radiation is obtained within a particular frequency band and left-handed CP radiation is obtained within a different frequency band. Numerical analysis results obtained using two different techniques confirm the prediction for this dual-band counter-CP radiation. The 1-MTM SPA used for the confirmation shows an overlapping gain and axial ratio bandwidth of approximately 7%. The VSWR relative to the Bloch impedance value is less than two within the overlapping bandwidth, as desired. Experimental data are also presented.
Bilateral Rolandic operculum processing underlying heartbeat awareness reflects changes in bodily self‐consciousness (2017)

Exteroceptive bodily signals (including tactile, proprioceptive and visual signals) are important information contributing to self-consciousness. Moreover, prominent theories proposed that visceral signals about internal bodily states are equally or even more important for self-consciousness. Neuroimaging studies have described several brain regions which process signals related to bodily self-consciousness (BSC) based on the integration of exteroceptive signals (e.g. premotor cortex, angular gyrus, supramarginal gyrus and extrastriate body area), and that another brain region, the insula/operculum which is involved in interoception and interoceptive awareness, processes signals critical for self-awareness. Providing evidence for the integration of exteroceptive and interoceptive bodily signals, recent behavioral experiments have demonstrated that the manipulation of interoceptive (e.g. cardiac) signals, coupled with exteroceptive (e.g. visual) signals, also modulates BSC. Does this integration occur within or outside the structures described above? To this end, we adapted a recently designed protocol that uses cardio-visual stimulation to induce altered states of BSC to fMRI. Additionally, we measured neural activity in a classical interoceptive task. We found six brain regions (bilateral Rolandic operculum, bilateral supramarginal gyrus, right frontal inferior operculum and left temporal superior gyrus) that were activated differently during the interoception task as opposed to a control task. The brain regions which showed the highest selectivity for BSC based on our cardio-visual manipulation were found in the bilateral Rolandic operculum. Given our findings, we propose that the Rolandic operculum processes integrated exteroceptive-interoceptive signals that are necessary for interoceptive awareness as well as BSC.

Efficient Multimatch Packet Classification and Lookup with TCAM (2005)

Today's packet classification systems are designed to provide the highest-priority matching result, such as the longest prefix match, even if a packet matches multiple classification rules. However, new network applications demanding multimatch classification - that is, requiring all matching results instead of only the highest-priority match - are emerging. Ternary content-addressable memory is becoming a common extension to network processors, and its capability and speed make it attractive for high-speed networks. The proposed TCAM-based scheme produces multimatch classification results with about 10 times fewer memory lookups than a pure software approach. In addition, their scheme for removing negation in rule sets saves up to 95 percent of the TCAM space used by a straightforward implementation.
