Recent research has demonstrated top-down effects on meter induction in the auditory modality. However, little is known about these effects in the visual domain, especially without the involvement of motor acts such as tapping. In the present study, we aim to assess whether the projection of meter on auditory beats is also present in the visual domain. We asked 16 musicians to internally project binary (i.e., a strong-weak pattern) and ternary (i.e., a strong-weak-weak pattern) meter onto separate, but analog, visual and auditory isochronous stimuli. Participants were presented with sequences of tones or blinking circular shapes (i.e., flashes) at 2.4 Hz while their electrophysiological responses were recorded. A frequency analysis of the elicited steady-state evoked potentials allowed us to compare the frequencies of the beat (2.4 Hz), its first harmonic (4.8 Hz), the binary subharmonic (1.2 Hz), and the ternary subharmonic (0.8 Hz) within and across modalities. Taking the amplitude spectra into account, we observed an enhancement of the amplitude at 0.8 Hz in the ternary condition for both modalities, suggesting meter induction across modalities. There was an interaction between modality and voltage at 2.4 and 4.8 Hz. Looking at the power spectra, we also observed significant differences from zero in the auditory, but not in the visual, binary condition at 1.2 Hz. These findings suggest that meter processing is modulated by top-down mechanisms that interact with our perception of rhythmic events and that such modulation can also be found in the visual domain. The reported cross-modal effects of meter may shed light on the origins of our timing mechanisms, partially developed in primates and allowing humans to synchronize across modalities accurately.

Background: Incorrect or delayed diagnosis of melanoma may lead to inappropriate treatment, poor clinical outcomes, increased cost and medicolegal consequences. The provision of pertinent clinical information is essential for accurate pathological diagnosis of cutaneous melanocytic tumours. Failure to provide this information may contribute to poor outcomes. Objective: The aim of this article is to highlight important clinical information that clinicians can provide to pathologists to facilitate accurate diagnosis of melanocytic tumours. Discussion: Pertinent clinical information includes patient age, sex, tumour site, specimen orientation (if appropriate), history of the lesion, presence of any clinically or dermoscopically suspicious areas within the lesion (including apparent regression), access to any relevant clinical and/or dermoscopic photographs and prior pathology reports, melanoma history and risk factors, and history of concurrent or recent pregnancy. If the clinical features are not concordant with the pathology findings, the clinician and pathologist should discuss the case to identify the reason for incongruence.

The purpose of this study was to estimate combining ability of 58 sorghum lines previously selected for Aluminum (Al) tolerance. One hundred sixty-five hybrids were evaluated at three levels of Al saturation (0%, 20% and 50%) at the same season. General Combining Ability (GCA) effects were significant for female lines for all three traits. GCA effects for male lines were significant only for plant height. Specific Combining Ability (SCA) effects were significant only for flowering time. The ratio GCA to SCA was greater than the unity, indicating the prevalence of additive effects for the control of Al tolerance. F7, F14, F17, F20, F21, F24, F29, F31, F41, F42, F48, F51, F54 and F55 lines contributed to increase yield, while F29, F48 and F51 also contributed to reduce flowering time. M2 was the best male line since it contributed to increase yield and plant height, and to reduce flowering time. O objetivo deste trabalho foi estimar a capacidade combinatória de 58 linhagens parentais de sorgo previamente selecionadas para tolerância ao Alumínio (Al). Cento e sessenta e cinco híbridos obtidos a partir do cruzamento destas linhagens foram avaliados em três níveis de saturação de Al. A saturação de Al reduziu a altura das plantas de sorgo, mas não alterou a data de florescimento dos híbridos. A Capacidade Geral de Combinação (CGC) das linhagens fêmeas foi significativa para todas as características. A CGC dos machos foi significativa somente para altura de plantas. A Capacidade Específica de Combinação (CEC) foi significativa somente para dias para florescimento. As linhagens com maior CGC para produção de grãos foram F7, F14, F17, F20, F21, F24, F29, F31, F41, F42, F48, F51, F54, e F55, sendo que F29, F48 e F51 também contribuíram para reduzir a data de florescimento dos híbridos. M2 foi a melhor linhagem-macho.

We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected rotation ephemerides are achieved. A further dozen optical and/or X-ray binary systems co-located with LAT sources also likely harbor gamma-ray MSPs. This catalog thus reports roughly 340 gamma-ray pulsars and candidates, 10% of all known pulsars, compared to \\(\\leq 11\\) known before Fermi. Half of the gamma-ray pulsars are young. Of these, the half that are undetected in radio have a broader Galactic latitude distribution than the young radio-loud pulsars. The others are MSPs, with 6 undetected in radio. Overall, >235 are bright enough above 50 MeV to fit the pulse profile, the energy spectrum, or both. For the common two-peaked profiles, the gamma-ray peak closest to the magnetic pole crossing generally has a softer spectrum. The spectral energy distributions tend to narrow as the spindown power \\(\\dot E\\) decreases to its observed minimum near \\(10^{33}\\) erg s\\(^{-1}\\), approaching the shape for synchrotron radiation from monoenergetic electrons. We calculate gamma-ray luminosities when distances are available. Our all-sky gamma-ray sensitivity map is useful for population syntheses. The electronic catalog version provides gamma-ray pulsar ephemerides, properties and fit results to guide and be compared with modeling results.
