A framework of customizing transactions in persistent object management for advanced applications (2002)

In the new applications that support user cooperation using the power of distributed computers, users' processes in distributed hosts often share large data structures containing nested structure and pointers that often indicate persistent objects. Transactions usually manage concurrent accesses to shared persistent objects in such applications. Although various types of transaction schemes have been proposed for supporting cooperative applications, no single scheme provides efficient and appropriate semantics for all applications. We propose a system with a customizable framework for persistent object management. We classify transaction semantics into two major layers, the external transaction semantics, which manages relations between transactions, and the internal transaction semantics, which manages sharing among tasks within a transaction. The external transaction semantics is described according to the ACTA framework, a theoretical framework that is proposed for specifying the structure and behavior of transactions. We apply the ACTA framework to actual implementation of our transaction system, by mapping the ACTA's object sets into versioned object tables. The internal transaction semantics is described through distributed shared memory protocols. Versioned objects connect two layers into an integrated persistent object system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
360Anywhere (2018)

360-degree video is increasingly used to create immersive user experiences; however, it is typically limited to a single user and not interactive. Recent studies have explored the potential of 360 video to support multi-user collaboration in remote settings. These studies identified several challenges with respect to 360 live streams, such as the lack of gaze awareness, out-of-sync views, and missed gestures. To address these challenges, we created 360Anywhere, a framework for 360 video-based multi-user collaboration that, in addition to allowing collaborators to view and annotate a 360 live stream, also supports projection of annotations in the 360 stream back into the real-world environment in real-time. This enables a range of collaborative augmented reality applications not supported with existing tools. We present the 360Anywhere framework and tools that allow users to generate applications tailored to specific collaboration and augmentation needs with support for remote collaboration. In a series of exploratory design sessions with users, we assess 360Anywhere's power and flexibility for three mobile ad-hoc scenarios. Using 360Anywhere, participants were able to set up and use fairly complex remote collaboration systems involving projective augmented reality in less than 10 minutes.
Strong correlation between the complement-mediated antibody-dependent enhancement of HIV-1 infection and plasma viral load (1999)

We found strong association between the extent of the complement-mediated antibody-dependent enhancement of HIV-1 infection and the plasma viral load in HIV patients. On the basis of these findings, C-ADE correlates with HIV replication in vivo, and potentially contributes to the progression of HIV disease.
A Full 3D TCAD Simulation Study of Line-Width Roughness Effects in 65 nm Technology (2006)

For the 65nm technology node and beyond, new manufacturability problems are arising that strongly impact device and circuit behavior. Among these problems, line-edge and line-width roughness (LER and LWR) are of particular interest as dominant issues affecting parametric yield. In this paper, we investigate LWR effects by applying latest generation, full 3D TCAD technology including lithography simulation. In addition, our results answer open questions concerning the applicability of 2D slicing approximations vis a vis a 3D modeling effort. While LWR has been investigated by TCAD before, our methodology includes a full 3D process simulation (including lithography) without simplifications to generate the final transistor structures.
Chlorine precursor route (CPR) chemistry to poly(<i>p</i>‐phenylene vinylene)‐based light emitting diodes (1995)

Thin film organic electrolumiscent devices based on poly 2,3‐diphenyl‐1,4‐phenylenevinylene (DP‐PPV, see Fig.) have been fabricated using the chlorine‐precursor route. Devices with the configuration Mg/DP/‐PPV/ITO are shown to have an external quantum efficiency for green electroluminescence of 0.1%, a value comparable to the efficiency of CA/PPV devices. magnified image
Identification of molecular characteristics correlated with glioblastoma sensitivity to EGFR kinase inhibition through use of an intracranial xenograft test panel (2007)

In the current study, we examined a panel of serially passaged glioblastoma xenografts, in the context of an intracranial tumor therapy response model, to identify associations between glioblastoma molecular characteristics and tumor sensitivity to the epidermal growth factor receptor (EGFR) kinase inhibitor erlotinib. From an initial evaluation of 11 distinct glioblastoma xenografts, two erlotinib-sensitive tumors were identified, each having amplified EGFR and expressing wild-type PTEN. One of these tumors expressed truncated EGFRvIII, whereas the other expressed full-length EGFR. Subsequent cDNA sequence analysis revealed the latter tumor as expressing an EGFR sequence variant with arginine, rather than leucine, at amino acid position 62; this was the only EGFR sequence variant identified among the 11 xenografts, other than the aforementioned vIII sequence variant. EGFR cDNAs were then examined from 12 more xenografts to determine whether additional missense sequence alterations were evident, and this analysis revealed one such case, expressing threonine, rather than alanine, at amino acid position 289 of the extracellular domain. This glioblastoma was also amplified for EGFR, but did not display significant erlotinib sensitivity, presumably due to its lacking PTEN expression. In total, our study identified two erlotinib-sensitive glioblastoma xenografts, with the common molecular characteristics shared by each being the expression of wild-type PTEN in combination with the expression of amplified and aberrant EGFR.
Gender differences in predictors of mortality in nursing home residents with AD (2001)

These data suggest that the underlying mechanisms for AD may be different in men and women. Future studies of survival and progression of AD need to examine men and women separately.
Exploiting hierarchical domain structure to compute similarity (2003)

The notion of similarity between objects finds use in many contexts, for example, in search engines, collaborative filtering, and clustering. Objects being compared often are modeled as sets, with their similarity traditionally determined based on set intersection. Intersection-based measures do not accurately capture similarity in certain domains, such as when the data is sparse or when there are known relationships between items within sets. We propose new measures that exploit a hierarchical domain structure in order to produce more intuitive similarity scores. We extend our similarity measures to provide appropriate results in the presence of multisets (also handled unsatisfactorily by traditional measures), for example, to correctly compute the similarity between customers who buy several instances of the same product (say milk), or who buy several products in the same category (say dairy products). We also provide an experimental comparison of our measures against traditional similarity measures, and report on a user study that evaluated how well our measures match human intuition.
A study on GOOSE communication based on IEC 61850 using MMS ease lite (2007)

IEC 61850 “Communication networks and systems in substation” is not only the most advanced and universal standard for communication but also a comprehensive system oriented standard for substation automation system (SAS). The feature of IEC 61850 is that it covers communication, qualitative properties of engineering tools, measures for quality management, and configuration management. Based on high speed peer to peer communications (publisher/subscriber concept), the Generic Object Oriented System Event (GOOSE) is a model to transmit status information in fast way to multi devices, and is applied to trips, blockings, and all indications for automatics. The paper presents a study about communications in SAS and supplies a detailed analysis of the process of transferring GOOSE message supported by MMS EASE Lite tool from the user’s view point. The experiment results show the advantage of using such communication and MMS EASE Lite tool.
A new secondary side post regulator (SSPR) PWM controller for multiple output power supplies (2002)

There are a number of post regulator methods for power control in a multiple output power regulator. The most popular in the mid to high power range are magnetic amplifiers. The semiconductor equivalent of the magnetic amplifier is the secondary side post regulator (SSPR). SSPR has many advantages over the magnetic amplifier, especially in mid power, high frequency converters. This paper introduces a new SSPR controller, and demonstrates its performance with a forward converter design example.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis and biological activity of myricetin derivatives containing 1,3,4-thiadiazole scaffold (2017)

A series of myricetin derivatives containing 1,3,4-thiadiazole scaffold were synthesized, and their antibacterial activities against Xoo and Rs and their antiviral activity against TMV were evaluated. Bioassays indicated that some target compounds exhibited potential antibacterial and antiviral activities. These results indicated this kind of myricetin analogues could be further studied as potential alternative templates in the search for novel antibacterial and antiviral agents.
Narrowband frequency-hopping radars for the range estimation of moving and vibrating targets (2008)

An important task in urban sensing operation is accurate estimation and positioning tracking of moving targets. Equally important is target identifications and classifications based on distinctions in the respective motion signatures, such as targets encountering translation versus rotation or vibration motions or targets exhibiting linear versus nonlinear motions. Dual-frequency radars, which estimate the range of a target based on the phase difference between two closely spaced frequencies, have been shown to be a cost-effective method for this purpose. In particular, when time-frequency signal representation techniques are incorporated, Doppler signature enhancement and localization in the time-frequency domain enables robust range estimation of multiple targets with different motion profiles and small radar cross-sections. In this paper, the dual-frequency radar concept is extended to develop a narrowband (NB) frequency-hopping (FH) radar. The proposed NB-FH radar provides multifold advantages such as low probability of intercept, low interference to/from other systems, and flexible bandwidth usage for the improvement of range accuracy and phase unwrapping.
Optimal Joint Base Station Assignment and Beamforming for Heterogeneous Networks (2014)

Consider a downlink MIMO heterogeneous wireless network with multiple cells, each containing many mobile users and a number of base stations with varying capabilities. A central task in the management of such a network is to assign each user to a base station and design a linear transmit strategy to ensure a satisfactory level of network performance. In this work, we propose a formulation for the joint base station assignment and linear transceiver design problem based on the maximization of a system wide utility. We first establish the NP-hardness of the resulting optimization problem for a large family of α-fairness utility functions. Then, we propose an efficient algorithm to approximately solve this problem for a variety of different utility functions. Our numerical experiments show that the proposed algorithm can achieve significantly higher levels of system throughput and user fairness than what is possible by optimizing the precoders alone.
Oxidation of Anthracene and Benzo[a]pyrene by Laccases from Trametes versicolor (1996)

The in vitro oxidation of the two polycyclic aromatic hydrocarbons anthracene and benzo[a]pyrene, which have ionization potentials of <=7.45 eV, is catalyzed by laccases from Trametes versicolor. Crude laccase preparations were able to oxidize both anthracene and the potent carcinogen benzo[a]pyrene. Oxidation of benzo[a]pyrene was enhanced by the addition of the cooxidant 2,2(prm1)-azinobis(3-ethylbenzthiazoline-6-sulfonate) (ABTS), while an increased anthracene oxidizing ability was observed in the presence of the low-molecular-weight culture fluid ultrafiltrate. Two purified laccase isozymes from T. versicolor were found to have similar oxidative activities towards anthracene and benzo[a]pyrene. Oxidation of anthracene by the purified isozymes was enhanced in the presence of ABTS, while ABTS was essential for the oxidation of benzo[a]pyrene. In all cases anthraquinone was identified as the major end product of anthracene oxidation. These findings indicate that laccases may have a role in the oxidation of polycyclic aromatic hydrocarbons by white rot fungi.

Modified, cyclic dodecapeptide analog of neuropeptide Y is the smallest full agonist at the human Y<sub>2</sub> receptor (1996)

In order to stabilize the C-terminal dodecapeptide of neuropeptide Y (NPY) we replaced Leu28 and Thr32 by Lys and Glu, respectively, and subsequently linked these residues by lactamization. This peptide analog of NPY shows a more than 100-fold increase in affinity compared to the C-terminal linear dodecapeptide in receptor binding studies performed at human neuroblastoma cells SMS-KAN, which exclusively express the Y2 receptor subtype. Signal transduction was investigated by measuring Ca2+ current inhibition in human SH-SY5Y cells and cyclic [Lys28-Glu32] NPY Ac-25-36 and NPY were shown to be equipotent in this assay. Thus, this molecule is the smallest Y2 receptor selective full agonist of NPY. Using 2D-NMR experiments and molecular modelling techniques, the structures of the linear and cyclic peptides have been investigated and significant differences have been found, which may explain the improvement in biological activity. Thus, a model of the bioactive conformation of NPY at the human Y2 receptor is suggested.
Effecting frequency shifts with a DFT filterbank (2002)

It is often required to apply a shift in frequency to the channelised data within a DFT filterbank. An example application is the frequency domain implementation of the cyclic Wiener filter. A common approach is to rotate the transform through an appropriate number of bins, but this is only accurate if the frequency shift is a multiple of the bin width. A better approach is to combine the bin rotation with an approximate fine shift. The exact solution is found for an arbitrary DFT filterbank and novel, computationally efficient approximations to this are derived and compared.

Liquid Membrane Operations in a Microfluidic Device for Selective Separation of Metal Ions (2004)

A three-phase flow, water/n-heptane/water, was constructed in a microchannel (100-microm width, 25-microm depth) on a glass microchip (3 cm x 7 cm) and was used as a liquid membrane for separation of metal ions. Surface modification of the microchannel by octadecylsilane groups induced spontaneous phase separation of the three-phase flow in the microfluidic device, which allows control of interfacial contact time and off-chip analysis using conventional analytical apparatus. Prior to the selective transport of a metal ion through the liquid membrane in the microchannel, the forward and backward extraction of yttrium and zinc ions was investigated in a two-phase flow on a microfluidic device using 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester (commercial name, PC-88A) as an extractant. The extraction conditions (contact time of the two phases, pH, extractant concentration) in the microfluidic device were examined. These investigations demonstrated that the conventional methodology for solvent extraction of metal ions is applicable to solvent extraction in a microchannel. Finally, we employed the three-phase flow in the microchannel as a liquid membrane and observed the selective transport of Y ion through the liquid membrane. In the present study, we succeeded, for the first time, in the selective separation of a targeted metal ion from an aqueous feed solution to a receiving phase within a few seconds by employing a liquid membrane formed in a microfluidic device.
Versatile Self‐Complexing Compounds Based on Covalently Linked Donor–Acceptor Cyclophanes (2004)

A range of covalently linked donor-acceptor compounds which contain 1) a hydroquinone (HQ) unit, 2) a 1,5-dioxynaphthalene (DNP) ring system, or 3) a tetrathiafulvalene (TTF) unit as the pi-donor, and 4) cyclobis(paraquat-p-phenylene) (CBPQT(4+)) as the pi-accepting tetracationic cyclophane were prepared and shown to operate as simple molecular machines. The pi-donating arms can be included inside the cyclophane in an intramolecular fashion by virtue of stabilizing noncovalent bonding interactions. What amounts to self-complexing/decomplexing equilibria were shown to be highly temperature dependent when the pi-donating arm contains either an HQ or DNP moiety. The thermodynamic parameters associated with the equilibria have been unraveled by using variable-temperature (1)H NMR spectroscopy. The negative DeltaH degrees and DeltaS degrees values account for the fact that the "uncomplexed" conformation becomes the dominant species, since the entropy gain associated with the decomplexation process overcomes the enthalpy loss resulting from the breaking of the donor-acceptor interactions. The arm's in-and-out movements with respect to the linked cyclophanes can be arrested by installing a bulky substituent at the end of the arm. In the case of compounds carrying a DNP ring system in their side arm, two diastereoisomeric, self-complexing conformations are observed below 272 K in hexadeuterioacetone. By contrast, control over the TTF-containing arm's movement is more or less ineffective through the thermally sensitive equilibrium although it can be realized by chemical and electrochemical ways as a result of TTF's excellent redox properties. Such self-complexing compounds could find applications as thermo- and electroswitches. In addition, the thermochromism associated with the arm's movement could lead to some of the compounds finding uses as imaging and sensing materials.

Fibronectin-binding properties of the purified platelet glycoprotein IIb-IIIa complex. (1986)

Fibronectin binds to specific receptors on the surface of washed, thrombin-activated platelets. Evidence suggests that these receptors are closely associated with the platelet glycoprotein IIb-IIIa complex (GP IIb-IIIa). To determine whether GP IIb-IIIa itself can form a platelet receptor for fibronectin, we used a filtration assay to examine the interaction of purified fibronectin with purified GP IIb-IIIa incorporated into phospholipid vesicles. 125I-Fibronectin binding to the phospholipid vesicles required the presence of incorporated GP IIb-IIIa and was specific, time-dependent, reversible, saturable, and divalent cation-dependent (Mg2+ greater than Ca2+). The dissociation constant for 125I-fibronectin binding to the GP IIb-IIIa-containing vesicles in the presence of 2 mM MgCl2 was 87 nM. Proteins or peptides that inhibit 125I-fibronectin binding to whole platelets also inhibited 125I-fibronectin binding to the GP IIb-IIIa vesicles. Thus, specific 125I-fibronectin binding was inhibited by excess unlabeled fibrinogen or fibronectin, the anti-GP IIb-IIIa monoclonal antibody 10E5, the decapeptide from the carboxyl terminus of the fibrinogen gamma-chain, and the tetrapeptide Arg-Gly-Asp-Ser from the cell-binding domain of fibronectin. In contrast to results obtained using whole platelets, unlabeled fibronectin inhibited 125I-fibronectin binding to the GP IIb-IIIa vesicles. These results show that 125I-fibronectin binds directly to purified GP IIb-IIIa with most of the previously reported properties of 125I-fibronectin binding to washed, thrombin-stimulated platelets. Thus, GP IIb-IIIa has the potential to function as a platelet receptor for fibronectin as well as for fibrinogen.
