title: Low-frequency sound affects active micromechanics in the human inner ear

description: Noise-induced hearing loss is one of the most common auditory pathologies, resulting from overstimulation of the human cochlea, an exquisitely sensitive micromechanical device. At very low frequencies (&lt;250 Hz), however, the sensitivity of human hearing, and therefore the perceived loudness is poor. The perceived loudness is mediated by the inner hair cells of the cochlea, which are driven very inadequately at low frequencies. To assess the impact of low-frequency sound, we exploited a by-product of the active amplification of sound outer hair cells perform, so-called spontaneous otoacoustic emissions. These are faint sounds produced by the inner ear that can be used to detect changes of cochlear physiology. We show that a short exposure to perceptually unobtrusive, low-frequency sounds significantly affects outer hair cells: A 90 s, 80 dB(A) low-frequency sound induced slow, concordant and positively correlated frequency- and level oscillations of spontaneous otoacoustic emissions which lasted for about two minutes after low-frequency sound offset. Low-frequency sounds, contrary to their unobtrusive perception, strongly stimulate the human cochlea and affect amplification processes in the most sensitive and important frequency range of human hearing.

title: Data accompanying Timmins-Schiffman et al. 2013

description: These 3 files are the source data for Table 1 and Figures 3, 4, and 5 in Timmins-Schiffman et al. 2013 Elevated pCO2 causes developmental delay in early larval Pacific oysters, Crassostrea gigas, published in Marine Biology (doi 10.1007/s00227-012-2055-x). Table 1: Salinity, total alkalinity (AT), and spectrophotometric (spec) pH are point measurements taken each day. Partial pressure of CO2, carbonate saturation, and carbonate ion concentration were calculated from spec pH and AT. Mean and standard deviation (u ± SD) for the following parameters are given for all 3 days: temperature, salinity, AT, pH, pCO2, and carbonate ion concentration. Data from Figs 3 and 4: Each cell represents a measurement for an individual larva. Column headers are formatted [measurement type][pCO2].[day measurement taken], i.e. height400.day1 contains data for larval shell height from the 400 uatm treatment on day 1 post-fertilization. Data are for shell height and depth, pCO2 of approximately 400, 700, and 1000 uatm, and days 1 and 3 post-fertilization. Data for Fig 5: Data were plotted for individual oysters with measurements of both shell height and hinge length. Columns have data for day post-fertilization, pCO2 (in uatm), DayTreatment combined factor, hinge length, and shell height. Each row contains data for a single oyster larva.

title: Extension and magmatism in the Cerocahui basin, northern Sierra Madre Occidental, western Chihuahua, Mexico

description: The Sierra Madre Occidental of northwestern Mexico is the biggest silicic large igneous province of the Cenozoic, yet very little is known about its geology due to difficulties of access to much of this region. This study presents geologic maps and two new U-Pb zircon laser ablation inductively coupled plasma mass spectrometry ages from the Cerocahui basin, a previously unmapped and undated ~25 km-long by ~12 km-wide half-graben along the western edge of the relatively unextended core of the northern Sierra Madre Occidental silicic large igneous province. Five stratigraphic units are defined in the study area: (1) undated welded to non-welded silicic ignimbrites that underlie the rocks of the Cerocahui basin, likely correlative to Oligocene-age ignimbrites to the east and west; (2) the ca. 27.5–26 Ma Bahuichivo volcanics, comprising mafic-intermediate lavas and subvolcanic intrusions in the Cerocahui basin; (3) alluvial fan deposits and interbedded distal non-welded silicic ignimbrites of the Cerocahui clastic unit; (4) basalt lavas erupted into the Cerocahui basin following alluvial deposition; and (5) silicic hypabyssal intrusions emplaced along the eastern margin of the basin and to a lesser degree within the basin deposits.The main geologic structures in the Cerocahui basin and surrounding region are NNW-trending normal faults, with the basin bounded on the east by the syndepositional W-dipping Bahuichivo–Bachamichi and Pañales faults. Evidence of syndepositional extension in the half-graben (e.g. fanning dips, unconformities, coarsening of clastic deposits toward basin-bounding faults) indicates that normal faulting was active during deposition in the Cerocahui basin (Bahuichivo volcanics, Cerocahui clastic unit, and basalt lavas), and may have been active earlier based on regional correlations.The rocks in the Cerocahui basin and adjacent areas record: (1) the eruption of silicic outflow ignimbrite sheets, likely erupted from caldera sources to the east during the early Oligocene pulse of the mid-Cenozoic ignimbrite flare-up, mostly prior to synextensional deposition in the Cerocahui basin (pre-27.5 Ma); (2) synextensional late Oligocene mafic-intermediate composition magmatism and alluvial fan sedimentation (ca. 27.5–24.5 Ma), which occurred during the lull between the Early Oligocene and early Miocene pulses of the ignimbrite flare-up; and (3) post-extensional emplacement of silicic hypabyssal intrusions along pre-existing normal faults, likely during the early Miocene pulse of the ignimbrite flare-up (younger than ca. 24.5 Ma). The timing of extensional faulting and magmatism in the Cerocahui basin and surrounding area generally coincides with previous models of regional-scale middle Eocene to early Miocene southwestward migration of active volcanism and crustal extension in the northern Sierra Madre Occidental controlled by post-late Eocene (ca. 40 Ma) rollback/fallback of the subducted Farallon slab.
