Anomalous Flows at Dayside High-Latitude Magnetopause as Observed by Interball Tail Probe (2000)

We analyze magnetopause crossings at high latitudes dayside magnetopause as observed by Interball Tail probe. High time resolution plasma data show strong short-time flows near magnetopause that strongly deviate from surrounding magnetosheath flow. Several quasi- periodic velocity variations are observed at times. Plasma parameters, such as number density, temperature and bulk velocity-of these flows are close to magnetosheath values. These anomalous flows are observed almost at every magnetopause crossing in this region. The ion velocity distributions in these regions indicate the presence of open field lines. Observed properties of these flows suggest their association with reconnection at high latitudes.
<i>syn</i>‐Sesqui‐ and ‐Sesterbenzobicyclo[2.2.2]octene, Molecules with Stacked Benzene Rings (1991)

Molecular models for conduction in organic crystals with stacked π systems is a description, of syn-sesqui- and -sesterbenzobicyclo[2.2.2]-octene (structure of the latter in figure on the right) and their not yet synthesized higher homologues. The distances between the benzene rings are shorter than their van der Waals distances, so that extended molecular orbitals arise from overlapping of the benzene π orbitals.

A post-processing algorithm for short-circuit defect sensitivity reduction in VLSI layouts (2002)

Yield enhancement may well be regarded as the quintessential objective in microelectronic manufacturing. With diminishing feature size and increasing die area the amount of functional silicon on a die is too expensive to discard in the event of short-circuit and open-circuit faults. Designing chips with high tolerance against faults, therefore, holds a great promise for profitable manufacturing in the semiconductor industry. In this paper we propose a post-processing defect-tolerant routing algorithm that reduces or eliminates short-circuit sensitive area, and minimizes vias in a two-layer channel routing solution. The algorithm is built to be sensitive to manufacturer's defect pareto figures. This feature gives the designer the flexibility of customizing the routing algorithm to the desired defect-tolerant features without increasing the die area or interconnect length.
Heat Transfer and Thermoelectric Voltage at Metallic Point Contacts (1993)

Metallic point contacts have been extensively studied from the viewpoint of their interesting, and often nonlinear, electrical properties. Their thermal characteristics, however, have largely been ignored, even though they show great potential as microscale temperature sensors. It has been previously demonstrated that when a temperature drop exists across a point contact consisting of two identical metals, a thermoelectric voltage can be generated, provided the mean contact radius is comparable in size to the electron mean free path. In the present experimental study, a point contact is formed by pressing a sharply etched Ag whisker against either an Ag or a Cu flat plate. In addition to confirming the previous results, the feasibility of using such a point contact is demonstrated by calibrating the voltage output against the nondimensionalized plate temperature. Furthermore, the thermoelectric voltage at an Ag–Cu point contact is also presented, showing that a point contact made from dissimiliar metals is even more promising than one made from identical materials. Finally, the point-contact thermal resistance is shown to depend nonlinearly on the electrical resistance, or contact area, and on the temperature drop.
In vitro binding and expression studies demonstrate a role for the mouse Sry Q-rich domain in sex determination (1999)

The Q-rich domain of the mouse sex determining gene, Sry, is encoded by an in-frame insertion of a repetitive sequence composed of mostly CAG repeats. The exact function of this Q-rich domain is unknown. Studies on the polymorphisms within this Q-rich domain among different domesticus and musculus mouse strains suggest a possible role for this domain in sex determination. Using the farwestern protein-blotting technique and recombinant fusion proteins containing the Sry Q-rich domain as probes, three Sry interactive proteins of 94, 32 and 28 kDa apparent molecular weight (Sip-1, -2 and -3 respectively) were consistently detected in adult testis. Sip expression was detected in somatic cells and was associated with the spermatogenic activity of the testis. During embryogenesis, Sips were readily detected in total tissue extracts of embryos as early as E8.5 day. In fetal gonads of both sexes, their expression peaked around E11.5-13.5 day, at the time of sex determination and differentiation, and decreased drastically towards late stages of gestation. These observations support the hypothesis that the Q-rich domain may contribute to the biological function(s) of mouse Sry through a protein-protein interactive role(s).
Cortical screw support in femoral neck fractures: A radiographic analysis of 87 fractures with a new mensuration technique (1993)

In 87 femoral neck fractures, operated on with 2 von Bahr screws and followed for up to 2 years, the positions of the fixating screws were determined with a new mensuration technique which compensates for the variations in hip rotation in routine radiographs. The union rate of the fractures was related to the position of the screws. A posterior placement of the proximal screw and an inferior placement of the distal screw in both the femoral head and neck improved the outcome substantially.
Soybean Root Anatomy as Influenced by Soil Bulk Density<sup>1</sup> (1975)

Abstract This research was conducted under controlled greenhouse conditions to investigate the effects of soil compaction on soybean ( Glycine max L.) root antomy. Previous research has shown that high soil compaction reduces root efficiency in moving air, water, and nutrients into the plant. Increasing bulk density from 1.65 to 1.95 g/cm 3 altered the root anatomy. In the high density soil layers a larger percentage of the root volume was occupied by cell wall material, and the transverse sections of the roots had a wavy outline with ruptured epidermal cells. The vascular cylinder became more oval with a gradual increase in both casparian thickening in the endodermis and wall thickening in the xylem vessels.
A practical and highly efficient protocol for multicomponent synthesis of β-phosphonomalononitriles and 2-amino-4H-chromen-4-yl phosphonates using diethylamine as a novel organocatalyst (2012)

Diethylamine has been demonstrated for the first time to be a highly efficient organocatalyst in the solvent-free synthesis of β-phosphonomalononitriles by a three component condensation of aldehyde, malononitrile and dialkyl phosphite at ambient temperature. The applicability of the same catalyst in the synthesis of diethyl (2-amino-3-cyano-chromene-4-yl) phosphonic acid esters has also been described.
SHORT COMMUNICATION: Lack of initiating capacity of the genotoxic air pollutant 2-nitrofluorene in the mouse skin two-stage carcinogenesis system (1993)

2-Nitrofluorene (NF) is a potent genotoxic substance found in environments where incomplete combustion takes place. NF is a mutagen and a carcinogen in animal models. NF or 7,12-dimethylbenz[a]anthracene (DMBA) was administered once topically to female SENCAR mice followed by promotion by 12-O-tetradecanoylphorbol-13-acetate (TPA) in two different studies. TPA (2-5 micrograms) was administered twice a week for 13 or 19 weeks after initiation of DMBA (5-10 micrograms) or NF (50-1500 micrograms). DMBA administration (positive control) resulted in the formation of many papillomas, which were seen from week 8-9 after initiation. The negative controls administered acetone only were free of tumours. NF administration did not result in papilloma formation, even at high initiating doses of NF combined with a dose of TPA causing a systemic toxic effect in terms of a significant reduced body weight. The mechanism behind the absence of papilloma formation after administration of genotoxic and carcinogenic NF remains to be investigated.
Droplets Speeding on Surfaces (2001)

How fast a droplet will spread on a solid surface depends on the surface tension gradient and the wettability. The temperature dependence of the surface tension is exploited in a so-called Marangoni flow, but capillary forces can counteract this type of flow.
 Wasan
 et al.
 highlight the report by
 Danielet al., who have devised a method for harnessing the capillary flow such that it enhances the Marangoni flow. They achieve droplet speeds of up to 1.5 meters per second. The concept may be of interest in applications involving coatings, adhesion, and heat transfer.
Phages that display P-selectin antagonism (2002)

Selectins mediate adhesion events among leukocytes, platelets, and endothelial cells. Within the selectin family, P-selectin plays a predominant role in the recruitment of polymorphonuclear neutrophils into inflammatory sites and, thus, represents an important target for future therapies against
Temporal effects of thrombolytic agents on platelet function in vivo and their modulation by prostaglandins. (1990)

To examine the temporal effects of plasmin generated in vivo on platelet function, we infused tissue-type plasminogen activator (t-PA) in rabbits over 3 hours and measured ex vivo platelet aggregation. We noted an initial increase in the aggregation response to ADP occurring 30 minutes after the start of infusion. This enhanced response was short-lived and by 180 minutes was reduced, compared with pretreatment levels. Baseline aggregation response was restored by 240 minutes. This pattern of aggregation response to t-PA infusion was also seen with thrombin as the agonist. Coinfusion of either prostaglandin I2 or prostaglandin E1 abolished the initial hyperaggregable phase induced by t-PA; the hypoaggregable phase occurred earlier (after 60 minutes) and persisted throughout the 1-hour recovery period. Similarly, streptokinase infused for 1 hour also increased platelet aggregation at early times and then reduced aggregation responses after the first hour. Plasma plasmin activity increased as expected with t-PA infusion alone, peaking at 30 minutes and returning to baseline by the first hour. Interestingly, prostaglandin E1 blunted the rise in plasma plasmin activity. This same dose of prostaglandin E1 or prostaglandin I2 used alone did not appreciably alter platelet function at any time during the experiment. Our data show that therapeutic doses of t-PA or streptokinase produce a biphasic effect on platelet aggregation response in the rabbit. Coinfusion of either of the antiplatelet agents, prostaglandin E1 or prostaglandin I2, abolishes the hyperaggregable phase and prolongs the inhibitory effects on platelet aggregation produced by t-PA. These data suggest that the effects of thrombolytic agents on platelet function are complex and can be modulated by antiplatelet prostaglandins.
Embryonic morphogenesis signaling pathway mediated by JNK targets the transcription factor JUN and the TGF-β homologuedecapentaplegic (1997)

The dorsal surface of the Drosophila embryo is formed by the migration of the lateral epithelial cells to cover the amnioserosa. The Drosophila cJun-N-terminal kinase (DJNK) is essential for this process. Mutations in DJNK or the DJNK activator hemipterous (HEP) lead to incomplete dorsal closure, resulting in a hole in the dorsal cuticle. The molecules downstream of DJNK in this signaling pathway have not been established. Here we demonstrate that the basket1 (bsk1) mutation of DJNK causes decreased interaction with DJUN. Expression of decapentaplegic (DPP), a TGF-beta homologue, in the leading edge of the dorsal epithelium, is identified as a genetic target of the JNK pathway. A constitutive allele of JUN is able to rescue the dorsal closure defect of bsk1 and restores DPP expression. Furthermore, ectopic DPP rescues the defects in dorsal closure caused by bsk1. These data indicate that the interaction of DJNK with DJUN contributes to the dorsal closure signaling pathway and targets DPP expression.
Order‐disorder transformations in the lattice of organic molecules. II. The crystal structure of C(SCH<sub>3</sub>)<sub>4</sub> below 23.2°C (1943)

Abstract In this article the X‐ray investigation of tetramethylorthothiocarbonate C(SCH 3 ) 4 is described, a compound of particular interest with regard to its physical properties 1 ). The modification stable below 23.2°C proved to be tetragonal, space group P 42 1 c ( D 2d 4 ) Z = 2, a = 8.536 Å, c = 6.949 Å. A Bragg synthesis showed that the molecule C(SCH 3 ) 4 is built tetrahedrally with C ‐ S = 1.81 Å. The structure can be simply described as a packing of methyl groups ( r = 2 Å) arranged in a pattern resembling a body‐centred lattice, the interstices of which are alternately empty, or filled with a CS 4 group.
First evidence for injection statistics accuracy limitations in NAND Flash constant-current Fowler-Nordheim programming (2007)

We present for the first time the direct evidence of an injection statistical spread in the number of electrons placed into the floating-gate of deeply-scaled NAND Flash memories during constant-current Fowler-Nordheim programming. The spread directly affects the precision of the programmed levels and sets the ultimate accuracy of the NAND programming algorithm. Experimental results on technology nodes ranging from 90 nm to 60 nm reveal that the injection statistical spread increases as cell dimensions are reduced and this introduces a new constraint for future NAND memories design.
ApoA-I deficiency has a subtle effect on acute inflammatory responses after experimental Traumatic Brain Injury (2020)

Cerebral vascular injury is a common phenomenon after traumatic brain injury (TBI), with complications including vascular inflammation, decreased cerebral blood flow, and increased vessel tortuosity following TBI. Promoting cerebrovascular health may therefore be a useful therapeutic intervention after TBI. High density lipoproteins (HDL) are an attractive target due to their vasoprotective and anti-inflammatory roles in periphery vessels, but little is known on whether these benefits extend to the brain. Recently, deficiency of ApoA-I, the major protein constituent of circulating HDL, was shown to increase vascular associated plaque load in Alzheimer’s Disease (AD) mice, which may imply a vessel protective function of ApoA-I in the brain. This study was designed to test the novel hypothesis that ApoA-I deficiency would worsen acute vascular and inflammatory outcomes in mice after Closed-Head Impact Model of Engineered Rotational Acceleration (CHIMERA) TBI. ApoA-I KO and WT mice underwent single moderate-severe TBI. Histopathological outcomes at 6hr and 2 days (2D) post injury were assessed. ApoA-I deficient mice exhibited greater ICAM-1 immunoreactivity at the cortex at 2D post TBI compared to WT controls, and a subtle increase in brain cytokine levels, potentially suggesting role of ApoA-I in protecting from TBI induced inflammation.
Collisional excitation and radiative properties of N II - The strong intercombination (1D - 3P0) transition at 748 A (1991)

Laboratory measurements of EUV emission from electron-excited N2 have been obtained at medium resolution, providing N II EUV emission cross section measurements and allowing the confirmation of recent calculations by Fawcett (1987) indicating the presence of a strong intercombination line in N II at 748.37 A. The most recently available data are used to predict the basic collisional and radiative properties of N II, the plasma diagnostic properties are briefly explored, and radiative cooling coefficients are given. Some basic properties of electron-excited N II and N2 are examined in the EUV in order to diagnose emission spectra of the earth and Titan. The N II emissions in the earth dayglow, particularly at 916 A, are much brighter than current estimates of source rates. The N II 1085 A line in the dayglow contains a significant component from dissociative photoionization excitation. The N II 1085 A, 916 A, and 670 A lines in the Titan dayglow spectrum appear to be compatible with direct electron excitation of N2.

Effects of Activated Macrophages on <i>Nocardia asteroides</i> (1980)

The mechanism(s) of host resistance against Nocardia asteroides has not been well defined. Since disease due to N. asteroides frequently occurs in patients with impaired cell-mediated immunity, we studied the interaction of N. asteroides with activated and control mouse peritoneal macrophages. Activated macrophages were from mice infected with Toxoplasma gondii or injected with Corynebacterium parvum. N. asteroides in the early stationary phase (>99% in the coccobacillary form) was used for challenge of macrophage monolayers. Growth of two strains of N. asteroides was markedly inhibited in activated macrophages, whereas N. asteroides grew well in control macrophages. Quantitation of macrophage-associated N. asteroides indicated that activated macrophages killed 40 to 50% of N. asteroides within 6 h (P < 0.002). In control macrophage preparations, it appeared as if Nocardia filaments extended from within macrophages to the outside, and many of these filaments appeared to have extended to and then grown through neighboring macrophages. In activated macrophage preparations, Nocardia remained in the coccobacillary form in most macrophages. Control macrophage monolayers were almost completely overgrown with and destroyed by Nocardia 20 h after challenge, whereas activated macrophage monolayers remained intact. Nocardia that grew in control macrophages were not acid-alcohol fast or only weakly so, whereas the few Nocardia that grew in activated macrophages were strongly acid-alcohol fast. Our results indicate that activated macrophages may be important in host defense against N. asteroides.

Network Performance in Distributed HPC Clusters. (2005)

Linux-based clusters have become prevalent as a foundation for High Performance Computing (HPC) systems. As these clusters become more affordable and available, and with the emergence of high speed networks, it is becoming more feasible to create HPC grids consisting of multiple clusters. One of the attractions of such grids is the potential to scale applications across the various clusters. This creates a number of interesting opportunities as well as introduces a number of challenges. A key question is the impact of the inter-cluster network on the overall performance of the computing environment. In this paper, we report on recent experiments to evaluate such performance.
