Raw fMRI data from 12 rats used in the manuscript "Mapping of hemodynamic responses to the sensorymotor stimulation in a rodent model: a BOLD fMRI study"
No full textRaw data are from twelve male adult Wistar rats (Charles River Laboratories, Paris-France) weighing 300 ± 20g.
Rats were initially anesthetized (induction) with 3% isoflurane and were maintained under 0,7-0.8% (sedation along with a muscle relaxation) during fMRI session.
Each rat was submitted to two fMRI sessions: one with TE of 30 ms and and other with TE of 40 ms.
For fMRI acquisition, electrodes were inserted subcutaneously in the palmar surface of the right hindpaw of each rat and electrical stimulation (current pulses with a 1.7 mA amplitude, 10 ms duration and 8 Hz frequency) was applied in a block-design starting with a resting period of 25s as a baseline followed by 25s stimulation, repeated 8 times.
Ten 1-mm thick contiguous axial slices, from -6.36 mm to +2.64 mm to Bregma, were acquired with a two-shot gradient echo planar imaging (GE EPI) pulse sequence (2.56 cm2 FOV; 64x64 matrix size; a TR of 1000 ms; a flip angle of 50°) resulting in the pixel size of 0.4 mm.
All imaging experiments were performed on a 4.7T Bruker (Biospec 47/40, Bruker, GmbH, Ettlingen,Germany) with a horizontal bore magnet equipped with a 12 cm gradient coil (Bruker BGA12, 400 mT/m) and interfaced to AVANCE III console. Two actively decoupled RF coils were used: a 7.2-cm diameter volume coil for transmission and a 2-cm diameter surface coil (Rapid Biomedical, Rimpar, Germany) positioned on the top of the animal's head for reception
Root water status in three contrasted herbaceous species grown in rhizotrons
No full textThis dataset contains NMR and ecophysiological data that support the findings of a manuscript “Circadian variation of root water status in three herbaceous species assessed by portable NMR” submitted to Plants for publication. Data are acquired using NMR MOUSE® spectrometer as described in the article. For each plant, raw NMR depth profile data are in the compressed (win.rar RARLab® GmbH, Allemagne) file named “RawDataProfilesDactylis.rar, RawDataProfilesMedicago.rar and RawDataProfiles Plantago.rar”. The profiles acquired as the function of time are stored in the sequentially numbered binary .dat files with 4 colons. The first colon in contains the position of the measurement volume in micrometer, the second contains the average of the first 16 points of the 256 acquired echoes, the third one contains the average of the first 32 echoes whereas the fourth, which is used in the article, is the average value of the whole 256 echoes. The acquisition parameters are summarized in the acqu_XX.par file (where XX is the name of the species). The raw data of transversal echo decays for T2 measurements are in the compressed RawDadaT2DecaysXX.rar (XX= species name) which contain the numbered folders embedding the csv 3 colon-data file. The first colon is the time in ms, the two others are the real and imaginary part of the echo amplitude. The acquisition parameters are in in the acqu.par file located in the first folder. The full results of the nnls inversion of the echo decays wer also provided in the matlab (Matlab®, The MathWorks, Inc) .mat files DatctylisT2FitResultReg.mat, MedicagoT2FitResultReg.mat and PlantagoT2FitResultReg.mat
In addition to the NMR Data, a compressed file "Ecophy_data.rar" containing ecophysiological data in Excel format is provided. Each excel workbook named according to the name of the species (“Data_D_glomerata.xlsx”, “Data_P_lanceolata.xlsx”, and “Data_M_sativa.xlsx”) contains climatic chamber parameters (sheet Climatic Chamber), ecophysiological data (sheet Ecophysiology) along with a sheet “ReadMe” sheet, describing the file content. Only data acquired during NMR experiments (depth profiles and T2 measurements) are provided.
- The sheet “Climatic Chamber” is composed of 6 colons : the first contains the acquisition time of the CO2 concentration (colon 2) and of photosynthetic active radiation (colon 3). The fourth colon contains the acquisition time of air temperature (colon 5) and humidity (colon 6).
- The sheet “Ecophysiology” is composed of 5 colons. The two first contain the acquisition time and the values of soil humidity respectively. The third colon contains the acquisition time of leaf water potential whose values are provided in the colons 4 and 5 (one colon/leaf)
Dataset of NMR Profiles and T2 for 10 herbaceous species grown on rhizotron along with morphological and ecophysiological data
No full textThis dataset contains NMR (Profiles and T2 decay curves) and ecophysiological data acquired on 10 well-watered herbaceous species grown on rhizotron. Data were acquired using NMR MOUSE® spectrometer as described in the first article, 10.3390/plants10040782, based on 3 species and dealing with the state of water. In the present analysis, our aim was to understand the dynamics of root water quantity and mobility within roots during nychthemeral cycles for ten herbaceous species with contrasting root traits. The study was submitted to Plant and Soil journal for publication. The ReadMe file describes data organization in each workbook <br

Stability of the free equilibrium state of a nonlinear age structured model for a two-sex population
Full text linkThis paper focuses on the study of the stability of the free equilibrium state of a nonlinearage structured model. The spectral properties of semigroup, the Riesz-Fréchet-Kolmogorov(RFK) criterion in L2 combined to the Calkin algebra theory are used to obtain the stability resultof the free equilibrium state
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
