Apparent mass of small children: Experimental measurements
A test facility and protocol were developed for measuring the seated, vertical, whole-body vibration response of small children of less than 18 kg in mass over the frequency range from 1 to 45 Hz. The facility and protocol adhered to the human vibration testing guidelines of BS7085 and to current codes of ethics for research involving children. Additional procedures were also developed which are not currently defined in the guidelines, including the integral involvement of the parents and steps taken to maximize child happiness. Eight children were tested at amplitudes of 0.8 and 1.2 m/s2 using band-limited, Gaussian, white noise acceleration signals defined over the frequency interval from 1 to 50 Hz. Driving point apparent mass modulus and phase curves were determined for all eight children at both test amplitudes. All results presented a single, principal, anti-resonance, and were similar to data reported for primates and for adult humans seated in an automotive posture which provided backrest support. The mean frequency of the apparent mass peak was 6.25 Hz for the small children, as compared to values between 6.5 - 8.5 Hz for small primates and values between 6.5 - 8.6 Hz for adults seated with backrest support. The peak value of the mean, normalized, apparent mass was 1.54 for the children, which compares to values from 1.19 to 1.45 reported in the literature for small primates and 1.28 for adults seated with backrest support. ISO standard 5982, which specifies a mean, normalized, apparent mass modulus peak of 1.50 at a frequency of 4.0 Hz for adults seated without backrest support, provides significant differences
Cabling sequences of tunnels of torus knots
This is the second of three papers that refine and extend portions of our
earlier preprint, "The depth of a knot tunnel." Together, they rework the
entire preprint.
The theory of tunnel number 1 knots that we introduced in "The tree of knot
tunnels" yields a parameterization in which each tunnel is described uniquely
by a finite sequence of rational parameters and a finite sequence of 0's and
1's, that together encode a procedure for constructing the knot and tunnel. In
this paper we calculate these invariants for all tunnels of torus knots.Comment: 17 pages, 12 figures, to appear in Algebraic and Geometric Topolog

Local Regulation of Arterial Tone: an Insight into Wall Dynamics Using Mathematical Models
This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute, ASME Press, LCN London Centre for Nanotechnology, UCL University College London, UCL Engineering, the International NanoScience Community, www.nanopaprika.eu.We present herein a first attempt to integrate large and small scale phenomena within an image-based computational domain. The aim of the present study is to highlight some of the underlying mechanisms that govern cellular interaction in the vascular wall, using a nonlinear model of vasomotion. We show that macroscopic rhythmic activity and emergent phenomena can indeed reflect ion movements at the level of the individual cell
Econometric Inference, Cyclical Fluctuations, and Superior Information
This paper presents and assesses a procedure to estimate conventional parameters characterizing fluctuations at the business cycle frequency, when the economic agents' information set is superior to the econometrician's one. Specifically, we first generalize the conditions under which the econometrician can estimate these "cyclical fluctuation" parameters from augmented laws of motion for forcing variables that fully recover the agents' superior information. Second, we document the econometric properties of the estimates when the augmented laws of motion are possibly misspecified. Third, we assess the ability of certain information criteria to detect the presence of superior information.Block bootstrap, Hidden variables, laws of motion for forcing variables, Monte Carlo simulations
TeorÃa literaria andaluza en el siglo XIX
Tras la búsqueda y tras el análisis de los textos más importantes de Retórica y de Poética
editados durante el siglo XIX hemos llegado a la conclusión de que se escriben
abundantes obras y de que, entre ellas, existe una notable diversidad en los contenidos.
Hemos identificado, al menos, ocho modelos filosóficos diferentes que han determinado
propuestas de teorÃas literarias diversas: Sensualismo, Sensualismo mitigado o
sentimentalismo, Eclecticismo (Escuela de Escocia), Espiritualismo ecléctico,
Tradicionalismo, Neoescolasticismo, Idealismo, Krausismo y Otras corrientes como el
Utilitarismo y el Romanticismo. Durante este siglo, en AndalucÃa tenemos Preceptivas
orientadas por cada una de estas corrientes teóricas y también sigue vigente una lÃnea
clasicista que prolonga por textos del siglo XVIII que se siguieron reeditando y que
sirvieron de modelos a muchos manuales elaborados en esta centuria como, por ejemplo,
el Arte Poética (1674) de Nicolas Boileau (1636-1711), que habÃa sido traducido y
anotado por J. B. Madramany y Carbonell en 1787, influye en muchos tratados de poética
del siglo XIX, por ejemplo, en el del granadino Francisco de Paula MartÃnez de la Rosa
(1787-1862) que tanta difusión alcanzó durante varias década
Dewey et Gutmann : l'éducation civique comme nécessité démocratique
Cet article réfléchit à la place de l’éducation civique dans nos sociétés démocratiques. Il sera défendu que l’espace démocratique exige l’inculcation de certaines vertus civiques afin de préserver pluralisme et autonomie dans nos sociétés démocratiques, valeurs fondamentales à toute vie démocratique. Pour ce faire, nous développerons, à partir des travaux de John Dewey et Amy Gutmann, une théorie de l’éducation où vie en démocratie exige des citoyens la maitrise de différentes aptitudes qui leur permettent de pleinement tirer les bénéfices de la vie commune. Une telle conclusion reposera principalement sur les concepts de croissance et d’environnement social introduits par la philosophie pragmatique de Dewey
