A framework for a national broadband (ATM/B-ISDN) network (1990)

The authors propose a hybrid packet- and circuit-switched network as a framework for a national broadband (ATM/B-ISDN) (asynchronous transfer mode/broadband-integrated services digital network). Built on the observation that transmission speeds are likely to remain much faster than switching speeds (thus packet switching at peak transmission rates needs to be avoided), the network architecture is a three-tier hierarchy composed of LANs (local area networks), network nodes and DACS (digital access and cross-connect systems). Access to the network is either through direct connection to a DACS or network node, or through the end-user's LAN, which has a gateway to a network node. Each network node is a high-performance ATM packet switch, which accepts input cells at a B-ISDN rate of 150 Mb/s and serves both as LAN-to-LAN interconnect and as a packet concentrator for traffic destined to other network nodes and LANs. To minimize the delay and simplify the implementation of gigabit-per-second packet switching, the network nodes are interconnected by a backbone network of multi-gigabit-per-second fibers and DACS, which provide reconfigurable circuits between network nodes. A congestion control technique using channel sharing that dramatically reduces the required buffer size is proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Low-loss and compact TFF-embedded silica-waveguide WDM filter for video distribution services in FTTH systems (2004)

Silica-waveguide 1.50/1.55 /spl mu/m WDM filters with a TFF-embedded configuration have been developed for video distribution services in FTTH systems. These filters exhibit low insertion losses of less than 1 dB and high reliability.
Console over Ethernet. (2003)

While console support is one of the most mundane portions of an operating system, console access is critical, especially during system debugging and for some low-level system-administration operations. As a result, densely packed servers and server appliances have either keyboard/video/mouse (KVM) cabling and KVM switches or serial ports, cabling, and concentrators. Further increases in the density of server appliances and blades require eliminating these items. We did so in the design of a prototype dense-server-blade system that includes none of the standard external ports for console devices. Since the standard means for console accesss, KVM or serial, were not possible, we developed lowlevel software to redirect console activity to the Ethernet interface. This paper describes the console support over the network interface that we developed for both our LinuxBIOS-based boot-time firmware and the Linux operating system. We refer to this code as console over Ethernet or etherconsole. We found it invaluable in debugging and evaluating our prototype server blades. We also describe ways of extending our work to make it more transparent to existing firmware and operating systems.
Adaptive projection augmented reality with object recognition based on deep learning (2019)

This study describes an Adaptive Projection Augmented Reality (AR) system that can provide information in real-time using object recognition. This approach is based on deep-learning through the construction of a 3D space from the real world. Through single system, a projector-camera unit with pan-tilt mechanism,, the 360-degree space of user surroundings can be built into a 3-dimensional space and accomplish object and user recognition. a projection AR environment can be generated instantaneously. Information relevant to real-world objects can be provided through real-time interactions between the user and objects. Using spatial interaction, it also allows for achieving intuitive interactions with projection information, user interface (UI), and contents without touch sensors. Several scenarios for the use of this system are described below.
Advanced method for oligonucleotide deprotection (2000)

A new procedure for rapid deprotection of synthetic oligodeoxynucleotides has been developed. While all known deprotection methods require purification to remove the residual protective groups (e.g. benzamide) and insoluble silicates, the new procedure based on the use of an ammonia-free reagent mixture allows one to avoid the additional purification steps. The method can be applied to deprotect the oligodeoxynucleotides synthesized by using the standard protected nucleoside phosphoramidites dG(iBu), dC(Bz)and dA(Bz).

Nanocomputers and reversible logic (1994)

An overview of nanocomputers is given, including a discussion of reversible computing techniques and an explanation of why they are necessary. The design of a nanocomputer will specify every atom and covalent bond present in the device. We can reasonably expect the switches, gates, or other embodiment of the logical elements to be on the order of a nanometer in size. (They may have to be further apart than that if electrical, due to electron tunneling.) In any case, it is quite reasonable to expect the entire computer to be smaller than a cubic micron, which contains a billion cubic nanometers. There are two new design rules that the nanocomputer designer must adopt: erase as few bits as possible, and eliminate entropy loss in operations that do not erase bits. The macroscopic strictures of the Second Law are consequences of the microscopic reversibility of the laws of physics. There are some hints that the oddities of quantum mechanics may have a similar source. One speculates that under the proper formulation, information, like energy, is a conserved quantity in the universe.

Microbial degradation of thermo‐oxidized low‐density polyethylene (1999)

Thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and Fourier transform infrared spectroscopy (FTIR) were used to determine the relative heat of fusion, crystallinity, and composition of thermo-oxidized low-density polyethylene (LDPE) inoculated with Phanerochaete chrysosporium and incubated for 3 months at 30°C under nonaseptic conditions. DSC analysis of thermo-oxidized samples (150°C, 120 h) followed by microbiological treatment showed a remarkable reduction on the heat of fusion (36%) compared to that of untreated LDPE. TGA allowed determination of changes due to the biological activity but not those that occurred by thermal treatment. A significant increase in the carbonyl index of the thermally treated (150°C, 120 h) LDPE samples was observed due to the increase in the oxidation level during this treatment. In contrast, the double-bond index (evaluated by FTIR) increased considerably (23%) as a result of the microbial treatment. The observed structural and morphological modifications of the biologically treated LDPE indicate that the reduction of the chain size may be carried out by scission mechanisms. © 1999 John Wiley & Sons, Inc.

Early Corneal Wound Healing and Inflammatory Responses After SMILE: Comparison of the Effects of Different Refractive Corrections and Surgical Experiences (2016)

The early inflammatory and wound healing responses after SMILE were minimal. In the early postoperative period, less surgical experience resulted in an increased inflammatory response in low myopic corrections. Greater keratocyte response was seen in high myopic corrections irrespective of surgeon experience. [J Refract Surg. 2016;32(5):346-353.].
Fe3O4 nanoparticle-integrated graphene sheets for high-performance half and full lithium ion cells (2011)

We synthesized Fe(3)O(4) nanoparticle/reduced graphene oxide (RGO-Fe(3)O(4)) nanocomposites and evaluated their performance as anodes in both half and full coin cells. The nanocomposites were synthesized through a chemical co-precipitation of Fe(2+) and Fe(3+) in the presence of graphene oxides within an alkaline solution and a subsequent high-temperature reduction reaction in argon (Ar) environment. The morphology and microstructures of the fabricated RGO-Fe(3)O(4) nanocomposites were characterized using various techniques. The results indicated that the Fe(3)O(4) nanoparticles had relatively homogeneous dispersions on the RGO sheet surfaces. These as-synthesized RGO-Fe(3)O(4) nanocomposites were used as anodes for both half and full lithium-ion cells. Electrochemical measurement results exhibit a high reversible capacity which is about two and a half times higher than that of graphite-based anodes at a 0.05C rate, and an enhanced reversible capacity of about 200 mAh g(-1) even at a high charge/discharge rate of 10C (9260 mA g(-1)) in half cells. Most important of all, these fabricated novel nanostructures also show exceptional capacity retention with the assembled RGO-Fe(3)O(4)/LiNi(1/3)Mn(1/3)Co(1/3)O(2) full cell at different C rates. This outstanding electrochemical behavior can be attributed to the unique microstructure, morphology, texture, surface properties of the nanocomposites, and combinative effects from the different chemical composition in the nanocomposites.
A Protective Lipidomic Biosignature Associated with a Balanced Omega-6/Omega-3 Ratio in fat-1 Transgenic Mice (2014)

A balanced omega-6/omega-3 polyunsaturated fatty acid (PUFA) ratio has been linked to health benefits and the prevention of many chronic diseases. Current dietary intervention studies with different sources of omega-3 fatty acids (omega-3) lack appropriate control diets and carry many other confounding factors derived from genetic and environmental variability. In our study, we used the fat-1 transgenic mouse model as a proxy for long-term omega-3 supplementation to determine, in a well-controlled manner, the molecular phenotype associated with a balanced omega-6/omega-3 ratio. The fat-1 mouse can convert omega-6 to omega-3 PUFAs, which protect against a wide variety of diseases including chronic inflammatory diseases and cancer. Both wild-type (WT) and fat-1 mice were subjected to an identical diet containing 10% corn oil, which has a high omega-6 content similar to that of the Western diet, for a six-month duration. We used a multi-platform lipidomic approach to compare the plasma lipidome between fat-1 and WT mice. In fat-1 mice, an unbiased profiling showed a significant increase in the levels of unesterified eicosapentaenoic acid (EPA), EPA-containing cholesteryl ester, and omega-3 lysophosphospholipids. The increase in omega-3 lipids is accompanied by a significant reduction in omega-6 unesterified docosapentaenoic acid (omega-6 DPA) and DPA-containing cholesteryl ester as well as omega-6 phospholipids and triacylglycerides. Targeted lipidomics profiling highlighted a remarkable increase in EPA-derived diols and epoxides formed via the cytochrome P450 (CYP450) pathway in the plasma of fat-1 mice compared with WT mice. Integration of the results of untargeted and targeted analyses has identified a lipidomic biosignature that may underlie the healthful phenotype associated with a balanced omega-6/omega-3 ratio, and can potentially be used as a circulating biomarker for monitoring the health status and the efficacy of omega-3 intervention in humans.

Toward Increasing Fairness in Score Scale Calibrations Employed in International Large-Scale Assessments (2013)

In this article, we investigate the creation of comparable score scales across countries in international assessments. We examine potential improvements to current score scale calibration procedures used in international large-scale assessments. Our approach seeks to improve fairness in scoring international large-scale assessments, which often ignore item misfit in score scale calibrations. We also seek to obtain improved model-data fit estimates when calibrating international score scales. To this end, we examine the use of two alternative score scale calibration procedures: (a) a language-based score scale and (b) a more parsimonious international scale wherein a large proportion of international parameters are used with a subset of country-based parameters for items that misfit in the international scale. In our analyses, we used data from all 40 countries participating in the Progress in International Reading Literacy Study. Our findings revealed that current score scale calibration procedures yield large numbers of misfitting items (higher than 25% for some countries). Our proposed approach diminished the effects of proportion of item misfit on score scale calibrations and also yielded enhanced model-data fit estimates. These results lead to enhancing confidence in measurements obtained from international large-scale assessments.
Focus Measure for Synthetic Aperture Imaging Using a Deep Convolutional Network (2019)

Synthetic aperture imaging is a technique that mimics a camera with a large virtual convex lens with a camera array. Objects on the focal plane will be sharp and off the focal plane blurry in the synthesized image, which is the most important effect that can be achieved with synthetic aperture imaging. The property of focusing makes synthetic aperture imaging an ideal tool to handle the occlusion problem. Unfortunately, to automatically measure the focusness of a single synthetic aperture image is still a challenging problem and commonly employed pixel-based methods include using variance or using a ”manual focus” interface. In this paper, a novel method is proposed to automatically determine whether or not a synthetic aperture image is in focus. Unlike conventional focus estimation methods which pick the focal plane with the minimum variance computed by the variance of corresponding pixels captured by different views in a camera array, our method automatically determines if the synthetic aperture image is focused or not from one single image of a scene without other views using a deep neural network. In particular, our method can be applied to automatically select the focal plane for synthetic aperture images. The experimental results show that the proposed method outperforms the traditional automatic focusing methods in synthetic aperture imaging as well as other focus estimation methods. In addition, our method is more than five times faster than the state-of-the-art methods. By combining with object detection or tracking algorithms, our proposed method can also be used to automatically select the focal plane that keeps the moving objects in focus. To the authors’ best knowledge, it is the first time that such a method of using a deep neural network has been proposed for estimating whether or not a single synthetic aperture image is in focus.

Characterization of Polypeptides Corresponding to Clones of Maize Zein mRNAS (1987)

Zeins, the storage proteins of maize (Zea mays) are a complex group of polypeptides encoded by a large multigene family. The alpha-zein proteins, which account for about 70% of the total, show both size and charge heterogeneity. Although clones corresponding to several different alpha zeins have been characterized, it has not been possible to correlate these sequences with individual zein polypeptides. By translating in Xenopus oocytes RNAs transcribed in vitro from cloned zein mRNAs, we were able to identify the encoded proteins among native zeins or zeins synthesized in oocytes with total zein mRNA. There was no correlation between the isoelectric points of these proteins and the homology of their coding DNA sequences, as the proteins encoded by two closely homologous cDNAs migrated with greater charge heterogeneity than those encoded by less homologous clones. In addition, the size of the proteins as determined by SDS polyacrylamide gel electrophoresis did not always correlate with the length of the protein deduced from the DNA sequence. The ability to match cloned zein sequences to individual native proteins will enable the genetic mapping of cloned genes as well as the analysis of their translational regulation.
Pump wavelength-dependent spectral-hole burning in EDFAs (1999)

Gain-difference spectra are used to show that 980-nm band pump wavelength changes can significantly effect spectral-hole burning (SHB) in erbium-doped fiber amplifiers (EDFAs). Gain measurements made using a number of different signal and pump wavelengths help to characterize the underlying inhomogeneous spectral properties of EDFAs and a framework for modeling these effects is presented. Despite the difficulty of obtaining the needed subpopulation specific cross section spectra, this model can be used to explain seemingly anomalous changes in the gain spectra of EDFA as a result of changes in signal or pump wavelength.
Quantified constraint satisfaction and bounded treewidth (2004)

Because the constraint satisfaction problem (CSP) is in general intractable, restricted cases of the CSP that are polynomial-time tractable have been heavily sought after. One class of restrictions that has been studied are variable-based restrictions, which concern the interaction among variables. In this paper, we consider the quantified constraint satisfaction problem (QCSP), a framework more general than the CSP. We present a QCSP tractability result arising from variable-based restrictions by giving a polynomial time algorithm for certain classes of QCSP instances having bounded treewidth.
Genetic determination of essential residues of the <i>Vibrio cholerae</i> actin cross‐linking domain reveals functional similarity with glutamine synthetases (2009)

Actin cross-linking domains (ACDs) are distinct domains found in several bacterial toxins, including the Vibrio cholerae MARTX toxin. The ACD of V. cholerae (ACD(Vc)) catalyses the formation of an irreversible iso-peptide bond between lysine 50 and glutamic acid 270 on two actin molecules in an ATP- and Mg/Mn(2+)-dependent manner. In vivo, cross-linking depletes the cellular pool of G-actin leading to actin cytoskeleton depolymerization. While the actin cross-linking reaction performed by these effector domains has been significantly characterized, the ACD(Vc) catalytic site has remained elusive due to lack of significant homology to known proteins. Using multiple genetic approaches, we have identified regions and amino acids of ACD(Vc) required for full actin cross-linking activity. Then, using these functional data and structural homology predictions, it was determined that several residues demonstrated to be important for ACD(Vc) activity are conserved with active-site residues of the glutamine synthetase family of enzymes. Thus, the ACDs are a family of bacterial toxin effectors that may be evolutionarily related to ligases involved in amino acid biosynthesis.
Polyethylenimine-functionalized graphene oxide as an efficient gene delivery vector (2011)

A novel gene delivery system based on graphene oxide chemically-functionalized with branched polyethylenimine (PEI-GO) is reported. The PEI-GO conjugate was formed by the covalent linking of PEI and GO via an amide bond by widely used EDC chemistry. Thus-prepared PEI-GO exhibits an excellent ability to condense DNA at a low mass ratio with a positive potential of 49 mV. A WST assay reveals that PEI-GO is significantly less cytotoxic than PEI 25 kDa. Finally, the transfection efficiency of PEI-GO was evaluated. It is demonstrated that the luciferase expression of PEI-GO is comparable or even higher than that of the PEI 25 kDa at optimal mass ratio. Moreover, intracellular tracking of Cy3-labelled pGL-3 indicates that PEI-GO could effectively deliver plasmid DNA into cells and be localized in the nucleus. These findings suggest that PEI-GO is a promising candidate for efficient gene delivery.
