Ultra-flat optical frequency comb generator using a single-driven dual-parallel Mach–Zehnder modulator (2014)

We propose and experimentally demonstrate a simple and cost-effective ultra-flat optical frequency comb (OFC) generator by directly modulating a standalone dual-parallel Mach-Zehnder modulator (DP-MZM) with only one radio frequency (RF) signal without any other assisting devices. Five- and seven-tone OFC with exactly the same intensity can be theoretically generated using two sets of parameters obtained by solving equations derived from the DP-MZM modulation model. In good agreement with the theoretical results, five- and seven-tone OFC with flatness of 0.1 and 1 dB are experimentally demonstrated, respectively.
Simple small‐size coupled‐fed uniplanar PIFA for multiband clamshell mobile phone application (2009)

Abstract In this study, a simple uniplanar printed PIFA occupying a small area of 10 × 40 mm 2 for achieving multiband operation in the clamshell mobile phone is presented. The proposed PIFA is formed by a simple shorted radiating strip coupled‐fed by a simple feeding strip and is mounted at the hinge of the clamshell mobile phone; further, the upper ground plane is connected to the main ground plane using an extended connecting strip. With the coupling feed and the connection arrangement between the main and upper ground planes, the proposed PIFA itself is not only an efficient radiator, it can also excite the two ground planes of the clamshell mobile phone as an efficient radiator (dipole‐like resonant modes are excited). Thus, with a small occupying area and a simple structure for the proposed PIFA, two wide operating bands at lower and higher frequencies can be provided to cover GSM850/900/1800/1900/UMTS bands for WWAN operation. The antenna also meets the 1‐g SAR specification of 1.6 W/kg required for practical applications. © 2009 Wiley Periodicals, Inc.

A new class of base-catalyzed Diels-Alder reactions of 2H-pyran-2,5-diones has been developed using catalytic amount of dicyclohexylmethylamine in tert-butyl alcohol. This method has been successfully employed for construction of the tricyclic core of basiliolide B at room temperature with good yields and exclusive endo selectivity.
Using an On-line UV-C Apparatus to Treat Harvested Fruit for Controlling Postharvest Decay (1997)

An apparatus was designed to deliver low-dose UV-C light to the surface of fruit on a processing line and tested for its control of postharvest decay. It consisted of a row of UV-C emitting lamps mounted on a frame above a conveyer belt that transported the fruit. The dosage of the UV-C light delivered to the fruit surface was regulated by varying the speed of the conveyor belt. Postharvest decay after 28 days storage of `Empire' apples was reduced 52% relative to the untreated checks when the fruit were conveyed at 6.2 m·min −1 (1.38 kJ·m −2 dose) under the UV-C apparatus. Factors affecting the practical application of UV-C irradiation of fruit for controlling postharvest decay are discussed.
Dendrite-Free Lithium Deposition with Self-Aligned Nanorod Structure (2014)

Suppressing lithium (Li) dendrite growth is one of the most critical challenges for the development of Li metal batteries. Here, we report for the first time the growth of dendrite-free lithium films with a self-aligned and highly compacted nanorod structure when the film was deposited in the electrolyte consisting of 1.0 M LiPF6 in propylene carbonate with 0.05 M CsPF6 as an additive. Evolution of both the surface and the cross-sectional morphologies of the Li films during repeated Li deposition/stripping processes were systematically investigated. It is found that the formation of the compact Li nanorod structure is preceded by a solid electrolyte interphase (SEI) layer formed on the surface of the substrate. Electrochemical analysis indicates that an initial reduction process occurred at ∼ 2.05 V vs Li/Li(+) before Li deposition is responsible for the formation of the initial SEI, while the X-ray photoelectron spectroscopy indicates that the presence of CsPF6 additive can largely enhance the formation of LiF in this initial SEI. Hence, the smooth Li deposition in Cs(+)-containing electrolyte is the result of a synergistic effect of Cs(+) additive and preformed SEI layer. A fundamental understanding on the composition, internal structure, and evolution of Li metal films may lead to new approaches to stabilize the long-term cycling stability of Li metal and other metal anodes for energy storage applications.
Interaction of synaptic modification rules within populations of neurons. (1985)

A theoretical account is given for long- and short-term changes in populations of neurons subject to independent rules for pre- and postsynaptic modification. The postsynaptic rule proposes that coactivated heterosynaptic inputs to a neuron alter the states of ion channels at a given synapse, thereby changing the susceptibility of these channels to local biochemical alterations. The resultant change in the population distribution of local channel states affects the postsynaptic potential produced at the synapse by subsequent inputs. This postsynaptic rule applies, in general, to short-term changes at specific individual synapses. In contrast, the presynaptic rule applies in general to long-term changes in the whole neuron, resulting in an altered probability of transmitter release. Because of neuroanatomical constraints, the presynaptic rule affects large numbers of synapses defined by the connectivity of that neuron and distributed nonspecifically over the population. We show that the combined action of the two independent rules upon populations of neurons arrayed in interconnected neuronal groups leads to consistent alterations of the probability of firing of certain circuits while maintaining variability in the response of the population to novel input. This "dual rules" model fulfills the requirements of the theory of neuronal group selection.
Series and parallel arc-fault circuit interrupter tests. (2013)

While the 2011 National Electrical Codeª (NEC) only requires series arc-fault protection, some arc-fault circuit interrupter (AFCI) manufacturers are designing products to detect and mitigate both series and parallel arc-faults. Sandia National Laboratories (SNL) has extensively investigated the electrical differences of series and parallel arc-faults and has offered possible classification and mitigation solutions. As part of this effort, Sandia National Laboratories has collaborated with MidNite Solar to create and test a 24-string combiner box with an AFCI which detects, differentiates, and de-energizes series and parallel arc-faults. In the case of the MidNite AFCI prototype, series arc-faults are mitigated by opening the PV strings, whereas parallel arc-faults are mitigated by shorting the array. A range of different experimental series and parallel arc-fault tests with the MidNite combiner box were performed at the Distributed Energy Technologies Laboratory (DETL) at SNL in Albuquerque, NM. In all the tests, the prototype de-energized the arc-faults in the time period required by the arc-fault circuit interrupt testing standard, UL 1699B. The experimental tests confirm series and parallel arc-faults can be successfully mitigated with a combiner box-integrated solution.
Ship localization using ais signals received by satellites (2013)

This paper addresses the problem of ship localization by using the messages received by satellites and transmitted by the automatic identification system (AIS). In particular, one considers the localization of ships that do not transmit their actual position in AIS signals. The proposed localization method is based on the least squares algorithm and uses the differences of times of arrival and the carrier frequencies of the messages received by satellite. A modification of this algorithm is proposed to take into account the displacement model of the ships as additional measurements. This modification shows a significant localization improvement.
Mathematics and the Imagination. (1940)

Emphasizes the approach to mathematics rather than an explanation of the hows and whys of the subject. The author argues that maths is analogous to a fairyland ruled by logic, and that the only restraint on what math can provide is the reader's lack of imagination in using its principles.
Regulation of Senescence in Cancer and Aging (2011)

Senescence is regarded as a physiological response of cells to stress, including telomere dysfunction, aberrant oncogenic activation, DNA damage, and oxidative stress. This stress response has an antagonistically pleiotropic effect to organisms: beneficial as a tumor suppressor, but detrimental by contributing to aging. The emergence of senescence as an effective tumor suppression mechanism is highlighted by recent demonstration that senescence prevents proliferation of cells at risk of neoplastic transformation. Consequently, induction of senescence is recognized as a potential treatment of cancer. Substantial evidence also suggests that senescence plays an important role in aging, particularly in aging of stem cells. In this paper, we will discuss the molecular regulation of senescence its role in cancer and aging. The potential utility of senescence in cancer therapeutics will also be discussed.
Efficiency of Precode-Only Raptor codes and Turbo-Fountain Codes (2006)

This paper deals with precode-only (PCO) Raptor and turbo fountain codes used on a noiseless channel, as it is the case for the BEC or the AWGN channel with high SNR. We find an expression for the performance of an ML-decoded PCO Raptor code. The performance parameter is the inefficiency of the code, i.e., the average amount of redundancy needed to decode the information bits. The inefficiency is expressed in terms of a generalized weight enumerating function. Also, we characterize the behavior of the Shannon ensemble in the same conditions. Finally, we extend the analysis to turbo fountain codes, which are iteratively decoded. We obtain an upper bound to the turbo code inefficiency when the deterministic interleaver is replaced by a uniform interleaver
A critical appraisal of drainage in syringomyelia (1995)

The use of drains in the treatment of syringomyelia has a simple and immediate appeal and has been practiced widely since the report of Abbe and Coley over 100 years ago. Good short-term results have been claimed in the past, but long-term outcome is largely unknown. An experience in Birmingham, England is reviewed in which 73 patients who had had some form of syrinx drainage procedure performed were subsequently followed up. In these cases, a total of 56 syringopleural and 14 syringosubarachnoid shunts had been inserted. Ten years after the operations, only 53.5% and 50% of the patients, respectively, continued to remain clinically stable. A 15.7% complication rate was recorded, including fatal hemorrhage, infection, and displacement of the drain from the pleural and syrinx cavities. At second operation or necropsy, at least 5% of shunts were discovered to be blocked. The effect of other drainage procedures that do not use artificial tubing, such as syringotomy and terminal ventriculostomy, was analyzed but found not to offer any substantial benefit. These results indicate that drainage procedures are not an effective solution to remedying the progressive, destructive nature of syringomyelia. It is suggested that, rather than attempting to drain the syrinx cavity, disabling the filling mechanism of the syrinx is more appropriate. Most forms of syringomyelia have a blockage at the level of the foramen magnum or in the subarachnoid space of the spine. Surgical measures that aim to reconstruct the continuity of the subarachnoid space at the site of the block are strongly recommended. Lowering the overall pressure of the cerebrospinal fluid is advocated when reestablishment of the pathways proves impossible. Syrinx drainage as an adjuvant to more physiological surgery may have a place in the treatment of syringomyelia. If two procedures are done at the same time, however, it is difficult to ascribe with certainty a success or failure, and it is suggested that the drainage procedure be reserved for a later attempt if the elective first operation fails.

Effect of Pulsed Electric Field Processing on Flavor and Color of Liquid Foods<sup>†</sup> (2016)

This review shows that pulsed electric field (PEF) is a non-thermal preservation method that uses electric pulses to inactivate microorganisms and most especially high-intensity pulsed electric field (HIPEF) treatment involving application of pulses of high voltage (typically 20–80 kV/cm) to foods placed between two electrodes could achieve better flavor preservation and color retention in liquid foods than heat processing. HIPEF processing has been shown to deliver safe and chill-stable fruit juices with fresh-like sensory and nutritional properties. In addition, studies have shown that hurdle application of the different non-thermal treatments offers synergistic advantage over separate application of the individual treatment. PEF treatment in combination with other hurdles (such as microfiltration with large pore ≥1.2 µm, ultraviolet irradiation, high-intensity light pulses, etc.) has the potential to increase the preservation of liquid foods while retaining sensory attributes. Practical Applications Non-thermal technology is one of the food processing and preservation methods that currently have been explored on a global scale. Pulsed electric fields (PEF) is a non-thermal preservation method that uses electric pulses to inactivate microorganisms and causes little or no change in food qualities. It is an efficient process that is employed to inactivate microorganisms and decrease the activity of enzymes without major undesirable effects on the organoleptic qualities of food products. PEF technology has not only proven to be effective in eliminating food microorganisms and inactivate enzymes, it also has a higher flavor and color retention properties than thermally processed foods.
Association of Plasma Homocysteine Level and Arterial Stiffness in Subjects with Type 2 Diabetes Mellitus (2013)

Objective: Plasma homocysteine (Hcy) is considered to be a marker of endothelial dysfunction and a predictor of cardiovascular disease (CVD). Arterial stiffness measured by brachial-ankle pulse wave velocity (baPWV) is not only a marker of vascular damage but a significant predictor of CVD. Previous studies about the effect of high plasma Hcy levels on arterial stiffness have yielded inconsistent results. We therefore assessed the association between Hcy and baPWV in a relatively large number of subjects with type 2 diabetes mellitus (DM). Methods: We retrospectively assessed plasma Hcy concentration and arterial stiffness in 1,477 Korean type 2 diabetic patients. Participants were also evaluated for plasma glucose, hemoglobin A1c (HbA1c), duration of DM, microvascular complications, lipid profile, and high sensitivity C-reactive protein (hsCRP). Arterial stiffness was measured noninvasively by baPWV. Results: Correlation analysis indicated a significant positive association between serum Hcy levels and baPWV (r=0.245, p<0.001). In a multiple linear regression analysis, the association between serum Hcy levels and baPWV was independent of traditional cardiovascular risk factors (standardized β=3.8, p=0.01). Conclusion: The results support the hypothesis that plasma Hcy levels are associated with arterial stiffness in patients with type 2 DM. Prospective studies are warranted to determine whether lowering serum Hcy level could reduce arterial stiffness and cardiovascular morbidity in type 2 DM.
Influence of divergent electric fields on space-charge distribution measurements by elastic methods (2000)

Elastic methods are presently being used to study the space charge distributions in insulators. They are limited in their interpretation to simple geometries whereas real systems often involve complex structures such as the case for divergent electric field regions. The authors propose a general theory for the interpretation of the data obtained by the pressure-wave-propagation method and the electro-acoustic method. This model makes it possible to study crystals, isotropic solids, or fluid samples of any geometry, containing charge and dipole distributions and also submitted to divergent electric fields such as produced by treeing or defects. A comparison is made with existing models in the case of simple geometries, such as planar or coaxial. It is shown that classical results are justified in the case of a planar sample. However, a correction has to be introduced in more complex geometries, even in coaxial ones. Indeed, some experiments show the associated difference. The model also emphasizes the similarities of the two elastic methods of measurement both for the analytical and experimental point of view.
High-Fidelity Calibration and Characterization of Hyperspectral Computed Tomography System (2019)

This document archives the results developed by the Lab Directed Research and Development (LDRD) project sponsored by Sandia National Laboratories (SNL). In this work, a numerical study was performed to show the feasibility of approximating the non-linear operator of SNL's unique high-energy hyperspectral computed tomography system as a sequence of linear operators. The four main results gained from this work include the development of a simulation test-bed using a particle-transport Monte Carlo approach; the demonstration to assemble a linear operator of almost-arbitrary resolution for a given narrow energy window, developing a compression approach to dramatically reduce the size of the linear operator via a spline approach, and the demonstration of using the linear operator to perform processing of x-ray data; in this case, the development of an iterative reconstruction method. This numerical study has indicated that if these results can be replicated on the SNL system, the improved performance could be revolutionary as the method to approximate the nonlinear operator for a hyperspectral CT system is not feasible to perform on a traditional CT system.
Design of Annulated Pyrazoles as Inhibitors of HIV-1 Reverse Transcriptase (2008)

Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are recommended components of preferred combination antiretroviral therapies used for the treatment of HIV. These regimens are extremely effective in suppressing virus replication. Structure-based optimization of diaryl ether inhibitors led to the discovery of a new series of pyrazolo[3,4-c]pyridazine NNRTIs that bind the reverse transcriptase enzyme of human immunodeficiency virus-1 (HIV-RT) in an expanded volume relative to most other inhibitors in this class.The binding mode maintains the beta13 and beta14 strands bearing Pro236 in a position similar to that in the unliganded reverse transcriptase structure, and the distribution of interactions creates the opportunity for substantial resilience to single point mutations. Several pyrazolopyridazine NNRTIs were found to be highly effective against wild-type and NNRTI-resistant viral strains in cell culture.
