- Measurement of small ion beams by thermal ionisation mass spectrometry using new 10(13)Ohm resistors.
- Koornneef JM1, Bouman C2, Schwieters JB2, Davies GR3.Author information 1Faculty of Earth and Life Sciences, Vrije Universiteit Amsterdam, de Boelelaan 1085, 1081HV Amsterdam, The Netherlands. Electronic address: j.m.koornneef@vu.nl.2Thermo Fisher Scientific, Hanna-Kunath-Str. 11, Bremen, 28199, Germany.3Faculty of Earth and Life Sciences, Vrije Universiteit Amsterdam, de Boelelaan 1085, 1081HV Amsterdam, The Netherlands.AbstractWe tested 5 newly manufactured - prototype - 10(13)Ohm resistors in the feedback loop of Faraday cup amplifiers to measure small ion beams by Thermal Ionisation Mass Spectrometry (TIMS). The high Ohmic resistors installed in the TRITON Plus at the VU University Amsterdam theoretically have 10 times lower noise levels relative to the default 10(11)Ohm resistors. To investigate the precision and accuracy of analyses using these new amplifiers we measured Sr and Nd isotopes of reference standards at a range of ion currents (3.2×10(-16) to 1×10(-12)A, corresponding to intensities of 32μV to 100mV on a default 10(11)Ohm amplifier) and on small amounts of material (100 and 10pg). Internal precision and external reproducibility for Sr and Nd isotope ratios are both better when collected on 10(13) compared 10(12)Ohm resistors and to the default 10(11)Ohm resistors. At an (87)Sr ion current of 3×10(-14)A (3mV on a 10(11)Ohm amplifier) the internal precision (2 SE) of (87)Sr/(86)Sr is 5 times better for 10(13)Ohm resistors compared to 10(11)Ohm resistors. The external reproducibility (2 SD) at this beam intensity is 9 times better. Multiple 100 and 10pg Sr standards, ran to exhaustion, yielded low (87)Sr/(86)Sr compared to the long term average (e.g. 10pg average=0.710083±164 (n=11) instead of 0.710244±12, n=73). The average off-set for 10pg standards can be explained by a loading blank contribution of 1.3pg. In contrast, Nd data on 100pg and 10pg samples are accurate suggesting that Nd loading blanks do not compromise the data. The external reproducibility of (143)Nd/(144)Nd on 100pg samples is 125ppm and 3.3‰ on 10pg samples (2 RSD=relative standard deviation, n=10). Thus, variability in Nd and Sr isotope ratios in the 4th decimal place, e.g. (143)Nd/(144)Nd 0.5110-0.5119 or (87)Sr/(86)Sr 0.7100-0.7109, can be resolved in 10 to 100pg samples provided that the procedural blanks and chemical separation are optimal. For measurements in the beam intensity range usually covered by ion counting (<3mV or 2×10(5)cps) we obtain a (143)Nd/(144)Nd internal precision (2 SE) of 480ppm for a (143)Nd intensity of 6.25×10(4)cps (1mV) and 1% at an intensity of 2×10(3)cps (32μV on a 10(11)Ohm amplifier). We find that at intensities higher than 2×10(4)cps the precision using the 10(13)Ohm resistors is better than for ion counting owing to instability and non-linearity behaviour of the ion counting system. Our results indicate that between 2×10(4)cps and an ion current of 2×10(-13)A (20mV on a 10(11)Ohm amplifier) it is beneficial to use the high gain amplifiers instead of (multi) ion counting or Faraday cups equipped with the standard 10(11)Ohm resistors. This finding suggests that the newly developed high gain resistors could potentially be valuable in applications that currently use (multiple) ion counting to measure small ion beams (e.g. U-series, Re-Os, Pu, Pb). In addition to improved precision, the use of Faraday cups equipped with high resistance amplifiers is more practical in terms of the required calibration procedure and in the flexibility in the collector set-up compared to using multiple ion counting arrays.

- Core number representations are shaped by language.
- Salillas E1, Carreiras M2.Author information 1Basque Center on Cognition Brain and Language, San Sebastian, Spain. Electronic address: e.salillas@bcbl.eu.2Basque Center on Cognition Brain and Language, San Sebastian, Spain; IKERBASQUE, Basque Foundation for Science, Bilbao, Spain.AbstractLanguage and math have been predominantly related through exact calculation. In the present study we investigated a more fundamental link between language and math: whether the most basic quantity representation used for the contrast of numerosities could be shaped by language. We selected two groups of balanced, equally proficient Basque-Spanish bilinguals. Crucially, the two groups differed with respect to the language in which math had been learned at the point of earliest formal instruction in mathematics (Language of learning Math - LL(math)). They performed a simple comparison task between pairs of Arabic digits related through the decimal system or through the vigesimal system. The vigesimal system is retained in Basque for the naming of certain numerals, while for other numerals the decimal system is used, just as for all Spanish number words. Event-related potential (ERP) distance effects were taken as the dependent variable, indexing the activation of quantity. Results showed an N1-P2 distance effect during the comparison of digit pairs related through the base-10 system in both groups. Importantly, this N1-P2 effect appeared only for the group whose LL(math) was Basque when base-20 related digits were compared, even if both groups were perfectly fluent in Basque. Thus the early N1-P2 component appears to be sensitive to verbal components contained in quantity representation. Since the task did not contain any verbal input, the present data suggest that quantity representation may have verbal traces inherited from early learning. In turn, LL(math) should be the optimal medium for numerical communication.

A variety of imaging techniques such as catheter angiography, contrast enhanced computed tomography (CT) and cardiac magnetic resonance imaging (CMR) are routinely used to measure vascular diameters. Traditionally, CMR black blood sequences were the main anatomical tool for visualization of vascular anatomy and still are in many centers. More recently, the vessel diameters are measured on multiplanar reconstructions derived from static magnetic resonance angiography (MRA). This study was performed to investigate the variation of vessel diameter measurements on different CMR techniques with respect to their data acquisition scheme.
