Robert Peary's North Polar Narratives and the Making of an American Icon (2004)

In 1913, the Modern Historic Records Association of New York City published a copy of one of two records the explorer Robert Peary claimed to have left at the North Pole in 1909.1 It was one of a growing number of manuscripts and narratives produced by the explorer, his supporters and agents to document one of the most famous reported occurrences in American history. Peary's presumed attainment of the North Pole capped the larger story of America's 50-year quest of this geographical milestone. After more than two decades of arduous effort and a dangerous sledging excursion over the polar ice pack in 1909, Peary bested other competing nations, as well as rivals from his own country, to claim the prize. By heroic efforts, placing himself in continual danger and unimaginable difficulties, he demonstrated not only the superiority of his methods, but also the courage, resourcefulness, and perseverance necessary to victory. The achievement was a triumph for both the explorer and the American nation-state, confirming the United States in the pantheon of discovering nations, while adding Peary to the elite honor roll of explorers such as Columbus and Magellan, who brought Spain to global greatness four hundred years before. This, at least, summarizes Peary's version, which became the dominant account of the conclusion to the Race to the Pole, handed down in countless narratives and forms of media for nearly a century. Of course, as anyone familiar with the issue is aware, his triumph was initially disputed, and has again been
Presynaptic control of striatal dopamine neurotransmission in adult vesicular monoamine transporter 2 (VMAT2) mutant mice (2003)

The vesicular monoamine transporter 2 (VMAT2) plays a pivotal role in regulating the size of vesicular and cytosolic dopamine (DA) storage pools within the CNS, and can thus influence extracellular DA neurotransmission. Transgenic mice have been generated with a dramatically reduced (by approximately 95%) expression of the VMAT2 gene which, unlike complete knockout lines, survive into adulthood. We compared the pre-synaptic regulation of both impulse-dependent (exocytotic) and carrier-mediated (via reversal of the DA transporter, DAT) DA release in the dorsolateral caudate putamen (CPu) of striatal slices derived from adult homozygous VMAT2 mutant and wild-type mice using fast cyclic voltammetry. Impulse-dependent DA release, evoked by a single electrical pulse, was lower in homozygous (116 nm) than wild-type mice (351 nm) indicating smaller vesicular DA stores, an observation supported by the evanescent effect of amfonelic acid (300 nm) in homozygous mice. Amphetamine (2 microm) increased extracellular DA via DAT reversal in both wild-type (by 459 nm) and VMAT2 mutant (by 168 nm, p < 0.01 vs. wild-type) mice. In both cases, the effect was blocked by the DAT inhibitor GBR12935 (1 microm). Simultaneously, amphetamine decreased impulse-dependent DA release, albeit less in homozygous (by 55%) than in wild-type (by 78%) mice. In wild-types, this decrement was largely reversed by GBR12935 but not by the D2/D3 autoreceptor antagonist (-)sulpiride (1 microm). Conversely, in homozygous VMAT2 mutant mice, it was attenuated by (-)sulpiride but not GBR12935. The D2/D3 receptor agonist quinpirole inhibited impulse-dependent DA release with a lower EC50 value in homozygous mice (12 nm) compared with wild-types (34 nm), indicating the compensatory presence of functionally supersensitive release-regulating autoreceptors. However, analysis of DA reuptake kinetics obtained in the absence and presence of DAT blockade (by cocaine and amfonelic acid) revealed only minor differences in DAT functionality. These results demonstrate that impaired vesicular DA storage constrains extracellular DA levels in the dorsolateral CPu whether induced by either impulse-dependent or carrier-mediated mechanisms and that the relative importance of the DAT and terminal autoreceptors as control mechanisms in the actions of amphetamine are reversed in VMAT2 mutant mice.
A mutual capacitive normal-and shear-sensitive tactile sensor (1984)

A new type of tactile sensor is introduced for either robotics [1] or prosthetic applications. The sensor, made by IC microfabrication techniques, detects displacement of a shielding plate which alters the mutual capacitance between two electrodes. Both normal and shear sensitivity are obtained, and a 16% change of capacitance is produced by a normal stress of 5 gw/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Torque sensitivity can also be expected.
Unified publication and discovery of semantic Web services (2009)

The challenge of publishing and discovering Web services has recently received lots of attention. Various solutions to this problem have been proposed which, apart from their offered advantages, suffer the following disadvantages: (i) most of them are syntactic-based, leading to poor precision and recall, (ii) they are not scalable to large numbers of services, and (iii) they are incompatible, thus yielding in cumbersome service publication and discovery. This article presents the principles, the functionality, and the design of PYRAMID-S which addresses these disadvantages by providing a scalable framework for unified publication and discovery of semantically enhanced services over heterogeneous registries. PYRAMID-S uses a hybrid peer-to-peer topology to organize Web service registries based on domains. In such a topology, each Registry retains its autonomy, meaning that it can use the publication and discovery mechanisms as well as the ontology of its choice. The viability of this approach is demonstrated through the implementation and experimental analysis of a prototype.
Emission of Mg–Xe discharge and the MgXe excimer band (1980)

The emission intensities and excited-state densities of a Mg-doped high-pressure Xe discharge are reported. The normalized emission of the MgXe excimer band associated with the Mg 3 1P1–31S0 resonance transition is obtained from the data, as well as a 320–380 nm band attributed to XeMg+. The Mg2 A–X band is not seen in emission under any discharge conditions in Mg doped Xe or Ne. This Mg–Xe mixture does not appear to be a reasonable candidate for a discharge-excited excimer laser due to the large excitation energies associated with the Mg and Mg+ resonance transitions.
An evaluation of forensic similarity hashes (2011)

The fast growth of the average size of digital forensic targets demands new automated means to quickly, accurately and reliably correlate digital artifacts. Such tools need to offer more flexibility than the routine known-file filtering based on crypto hashes. Currently, there are two tools for which NIST has produced reference hash sets–ssdeep and sdhash. The former provides a fixed-sized fuzzy hash based on random polynomials, whereas the latter produces a variable-length similarity digest based on statistically-identified features packed into Bloom filters. This study provides a baseline evaluation of the capabilities of these tools both in a controlled environment and on real-world data. The results show that the similarity digest approach significantly outperforms in terms of recall and precision in all tested scenarios and demonstrates robust and scalable behavior.
Ruled by waves? Intracellular and intercellular calcium signalling (2000)

The field of calcium signalling has evolved rapidly the last 20 years. Physiologists had worked with cytosolic Ca2+ as the coupler of excitation and contraction of muscles and as a secretory signal in exocrine glands and in the synapses of the brain for several decades before the discovery of cellular calcium as a second messenger. Development of powerful techniques for measuring the concentration of cytosolic free calcium ions in cell suspensions and later in single cells and even in different cellular compartments, has resulted in an upsurge in the knowledge of the cellular machinery involved in intracellular calcium signalling. However, the focus on intracellular mechanisms might have led this field of study away from physiology. During the last few years there is an increasing evidence for an important role of calcium also as an intercellular signal. Via gap junctions calcium is able to co-ordinate cell populations and even organs like the liver. Here we will give an overview of the general mechanisms of intracellular calcium signalling, and then review the recent data on intercellular calcium signals. A functional coupling of cells in different tissues and organs by the way of calcium might be an important mechanism for controlling and synchronizing physiological responses
High-performance multi-channel fiber-based absolute distance measuring interferometer system (2009)

I describe the principle of operation and performance of a fiber-based absolute distance measuring interferometer system with 60 independent simultaneous channels. The system was designed for demanding applications requiring passive, electrically immune sensors with an extremely long MTTF. In addition to providing better than 0.3nm measurement repeatability at 5KHz for all channels, the system demonstrated absolute distance uncertainty of less than 5nm over a 500 micron measurement range.
Changes in levels of antibodies against the 70 kDa and a polypeptides of the U1RNP complex in relation to exacerbations of systemic lupus erythematosus. (1991)

In order to investigate whether disease exacerbations of systemic lupus erythematosus (SLE) are accompanied or preceded by changes in antibody levels against the U1RNA associated 70 kDa and A polypeptides, we prospectively collected plasma specimens from 71 patients with SLE. We compared changes in anti-70 kDa/anti-A levels, measured by ELISA using cloned antigens, with changes in levels of anti-dsDNA and total IgG. Measurable levels of anti-70 kDa (n = 10) and/or anti-A antibodies (n = 6) were detected during 10 exacerbations. Four of the 10 exacerbations with a measurable level of anti-70 kDa antibodies were preceded by a significant rise in anti-70 kDa levels, 2 by a significant fall, while levels of anti-70 kDa did not change in the remaining 4 cases. Only one of the 6 exacerbations with detectable anti-A antibody levels was preceded by a significant rise in anti-A antibodies, while levels did not change before exacerbation in the other 5 cases. Six of the 10 exacerbations were preceded by a significant rise in anti-dsDNA; in 4 cases levels of anti-dsDNA did not change before exacerbation. In contrast to anti-dsDNA, no relation was found between changes in levels of anti-70 kDa/anti-A and changes in disease activity. Significant changes in levels of anti-70 kDa/anti-A, occurring in 6 cases, were accompanied by parallel changes in total IgG in 5 of these 6. We conclude that, in contrast to anti-dsDNA, serial measurement of levels of anti-70 kDa/anti-A is not useful for monitoring disease activity or predicting disease exacerbations in SLE.(ABSTRACT TRUNCATED AT 250 WORDS)
PPP extensions for IP/PPP-HDLC over SONET-SDH/WDM (2003)

IP has emerged as the internetworking protocol of choice. IP is a best-effort protocol which provides no guarantee of delivery or ordering of packets at their destination. IP is designed to be transparent to the topology of the underlying transport network. This transparency is provided by a framing protocol operating over the data link or MAC layer. Due to the popularity of IP, attempts are underway to transport IP traffic over transport networks such as ADSL, HFC, ATM, SONET/SDH, and WDM. This paper examines the dynamics of IP traffic over SONET/SDH using PPP in HDLC-like framing. Although IP in ATM framing (IP/ATM/SONET) is also presented, the main focus of this paper is on IP/PPP/SONET and its extensions, such as PPP multilink, and PPP tunneling protocol. A discussion on the applicability of these PPP extensions to wavelength division multiplexing (WDM) networks is also presented in the conclusion.
Scour around spur dikes and bridge abutments (2001)

Abstract Realistic estimation of scour depth around spur dikes and bridge abutments in alluvial rivers is important for safe and economic design of their foundations. Procedures have been developed by previous investigators for determination of design scour depth in steady flows at abutments and spur dikes by making use of the design discharge. However, the time required by the design discharge to scour to its full potential is generally much larger than the time for which it runs. Therefore, computations on temporal variation of scour depth are also important for design purposes. Scour processes at bridge piers, abutments and spur dikes have been found to be similar except that the boundary layer effect induced by the channel wall upstream of the abutment or spur dike causes less scour around these as compared to the case of piers. In the present study, therefore, the concept of an analogous pier is developed. The analogous pier would have the same equilibrium scour depth as the given abutment or spur dike under similar hydraulic conditions. The parameters relating to drag due to flow around abutment/ spur dike and bridge pier have been found to be useful in establishing a relationship for the diameter of the analogous pier. The temporal variation of scour depth and the equilibrium scour depth at the spur dike and the abutment are then computed using pier scour equations with size of the analogous pier being taken as the pier diameter. Results obtained are verified using laboratory data of several investigators for both clear-water and live-bed scour conditions.
Taxonomy of the Species of Isoachlya Possessing Single Oospores (1955)

SUMMARYThirty-two isolates of Isoachlya, characterized by a single oöspore and clustered or glomerulate oögonia, were examined. Several specimens were intergrades between Isoachyla subterranea, I. itoana, and I. glomerata. These three are considered to be the same species, for which I. subterraneo is the valid binomial. Isoachlya unispora and I. intermedia are discussed. Observations of living specimens indicates that these are valid entities, and easily separable from I. subterranea.
Novel capacitor-isolated power converter (2010)

This paper presented a novel power conversion method of realizing the galvanic isolation by dual safety capacitors (Y-cap) instead of conventional transformer. With limited capacitance of the Y capacitor, series resonant is proposed to achieve the power transfer. The basic concept is to control the power path impedance, which blocks the dominant low-frequency part of touch current and let the high-frequency power flow freely. Conceptual analysis, simulation and design considerations are mentioned in this paper. An 85 W AC/AC prototype is designed and verified to substitute the isolation transformer of a CCFL LCD TV backlight system. Compared with the conventional transformer isolation, the new method is proved to meet the function and safety requirements of its specification while has higher efficiency and smaller size.

This review (over 380 references) summarizes metal–organic frameworks (MOFs), Materials Institute Lavoisier (MILs), iso-reticular metal–organic frameworks (IR-MOFs), porous coordination networks (PCNs), zeolitic metal–organic frameworks (ZMOFs) and porous coordination polymers (PCPs) with selected examples of their structures, concepts for linkers, syntheses, post-synthesis modifications, metal nanoparticle formations in MOFs, porosity and zeolitic behavior for applications in gas storage for hydrogen, carbon dioxide, methane and applications in conductivity, luminescence and catalysis.
THE RELATIONSHIP OF POLYMORPHONUCLEAR LEUKOCYTES TO INFERTILITY IN UTERI CONTAINING FOREIGN BODIES (1967)

A chronic infiltration of polymorphonuclear leukocytes was invariably found in the infertile regions of uteri containing foreign bodies in conventional rats, germfree rats, mice, and rabbits. Polymorphonuclear leukocytes were never found in the fertile regions of these uteri. A foreign body in the uterus of the rat, and probably also the mouse, was associated with a bacterial infection which spread the inflammatory response throughout the horn containing the foreign body, and in the mouse occasionally into the control horn as well. No bacteria could be cultured from the rabbit uterine horn containing a foreign body. In the germfree rat, both the infiltration of polymorphonuclear leukocytes into the uterus and fertility were significantly different from that observed in the conventional rat. Whereas in the conventional rat the inflammation and infertility extended along the entire length of the uterine horn containing a small foreign body, in the germfree rat the inflammation and infertility were closely correlated to the position of the foreign body. As judged by measurements of lysozyme in the uterine lumens of rats and rabbits, polymorphonuclear leukocytes released their contents into solution in the uterine lumen. It is concluded that some substance derived from polymorphonuclear leukocytes may exert toxic effects on fertilized ova or on spermatozoa and thus be responsible for the infertility of uteri containing foreign bodies.
Those Most Peculiar People: In Praise of Eccentricity (2009)

To borrow Edith Sitwell's phrasing: here come those who would entertain us. In their feathers and Lurex and headdresses worthy of Pharaohs, they swing their microphones and smash their guitars in the face of conformity. Here is Ozzy Osbourne, biting the head off his bat; here, David Bowie, in lightning-bolt mode, his hair dyed pickle red. And here - really here this time, in Sydney; not in some moonage daydream or tripping along the ghost road of eccentricity's history - comes the shaven-headed, 60-year-old Grace Jones, prowling and snarling like a near-six-foot-tall lady jaguar.
A method for the determination of freezing point of small quantities of biological fluids. (1952)

Abstract A resistance thermometry method for determining the freezing point of biologic fluids is described. The advantages of the method are its simplicity, accuracy, and adaptability for use with quantities of solution less than 5 ml. in volume.
Atmospheric trace elements at Enewetak Atoll: 1. Concentrations, sources, and temporal variability (1983)

The concentrations of 29 elements were measured in aerosol particles collected in 1979 during SEAREX experiments at Enewetak Atoll (11°N, 162°E) in the tropical North Pacific. The concentrations of Na, Mg, Cl, K, Ca, and Br were dominated by marine sources; these elements had similar mass‐size distributions, and their atmospheric concentration ratios (normalized to Na) were similar to the corresponding ratios in bulk seawater. Atmospheric inputs of aluminosilicate particles from crustal weathering controlled the aerosol particle concentrations of Al, Sc, Mn, Fe, Co, Cs, Ba, Ce, Eu, Hf, Ta, and Th. Mean concentrations of these crustally derived elements decreased by an average of 91% (±4.1%) from the local dry season (April to May) to the wet season (July to August); this general decrease was attributed to the abatement of dust storms in Asia. At times the influx of dust from Asia dominated the concentrations of V, Cr, Rb, and Cu in aerosol particles, but when dust concentrations decreased, noncrustal sources for these elements became apparent. A fourth group of elements (Zn, Se, Ag, Cd, Sb, I, and Pb) exhibited average, atmospheric concentrations that were higher than those expected from the flux of sea salt or the dispersal of mineral aerosol particles. Enrichments of these trace elements relative to average crustal material increased as the atmospheric dust concentrations subsided. Supplement is available with entire article on microfiche.

Floorplanning Considering IR Drop in Multiple Supply Voltages Island Designs (2010)

Voltage island has become a very effective design style for power saving in low-power design. However, the new design style also brings forward new challenges, especially to the designers of power/ground (P/G) networks. In this paper, we study the power delivery problem in voltage island designs, and propose to consider voltage drop during the floorplanning process to reduce design iterations. Our analysis shows that it is unnecessary to consider the pitch of the P/G network in the floorplan stage. By using the simplified searching strategy in floorplanning, we can obtain more robust low power design within reasonable runtime. Experimental results have demonstrated the effectiveness of our approach.
Molecular Targets of Manganese-Induced Neurotoxicity: A Five-Year Update (2021)

Understanding of the immediate mechanisms of Mn-induced neurotoxicity is rapidly evolving. We seek to provide a summary of recent findings in the field, with an emphasis to clarify existing gaps and future research directions. We provide, here, a brief review of pertinent discoveries related to Mn-induced neurotoxicity research from the last five years. Significant progress was achieved in understanding the role of Mn transporters, such as SLC39A14, SLC39A8, and SLC30A10, in the regulation of systemic and brain manganese handling. Genetic analysis identified multiple metabolic pathways that could be considered as Mn neurotoxicity targets, including oxidative stress, endoplasmic reticulum stress, apoptosis, neuroinflammation, cell signaling pathways, and interference with neurotransmitter metabolism, to name a few. Recent findings have also demonstrated the impact of Mn exposure on transcriptional regulation of these pathways. There is a significant role of autophagy as a protective mechanism against cytotoxic Mn neurotoxicity, yet also a role for Mn to induce autophagic flux itself and autophagic dysfunction under conditions of decreased Mn bioavailability. This ambivalent role may be at the crossroad of mitochondrial dysfunction, endoplasmic reticulum stress, and apoptosis. Yet very recent evidence suggests Mn can have toxic impacts below the no observed adverse effect of Mn-induced mitochondrial dysfunction. The impact of Mn exposure on supramolecular complexes SNARE and NLRP3 inflammasome greatly contributes to Mn-induced synaptic dysfunction and neuroinflammation, respectively. The aforementioned effects might be at least partially mediated by the impact of Mn on α-synuclein accumulation. In addition to Mn-induced synaptic dysfunction, impaired neurotransmission is shown to be mediated by the effects of Mn on neurotransmitter systems and their complex interplay. Although multiple novel mechanisms have been highlighted, additional studies are required to identify the critical targets of Mn-induced neurotoxicity.
Image Encryption with Variable Length Key (2015)

We propose a new image encryption algorithm with variable length running key based on a modified tent map. This modified tent map can generate uniform distribution pseudo-random number sequence. In the proposed image encryption, we employ the strategy of variable length running key which enlarges key value space, the strategy of one-time running key which is resilient to known/chosen plaintext attack, the strategy of cipher disturbance which minimizes dynamical degradation of digital chaos. Simulations have been carried out and the results demonstrate the strong survival ability of our scheme.
