Seeing relativity -- I. Ray tracing in a Schwarzschild metric to explore the maximal analytic extension of the metric and making a proper rendering of the stars

Publisher: name: arXiv

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We present an implementation of a ray tracing code in the Schwarzschild metric. We aim at building a numerical code with a correct implementation of both special (aberration, amplification, Doppler) and general (deflection of light, lensing, gravitational redshift) relativistic effects so as to simulate what an observer with arbitrary velocity would see near, or possibly within, the black hole. We also pay some specific attention to perform a satisfactory rendering of stars. Using this code, we then show several unexplored features of the maximal analytical extension of the metric. In particular, we study the aspect of the second asymptotic region of the metric as seen by an observer crossing the horizon. We also address several aspects related to the white hole region (i.e., past singularity) seen both from outside the black hole, inside the future horizon and inside the past horizon, which gives rise to the most counter-intuitive effects.

description: Bruxelles: cinq fois capitale. Bruxelles assume aujourd'hui son rôle de supercapitale: siège des principales institutions européennes (la Commission, le secrétariat du Conseil des Ministres, le Comité économique et social, le Comité des Régions). Elle partage avec Strasbourg la fonction parlementaire européenne et héberge bon nombre d'organisations internationales, en particulier l'OTAN. Et pourtant ... Bruxelles demeure d'abord et avant tout une « capitale provinciale », c'est-à-dire une ville construite au fil des siècles sur le modèle rhénan : Commune bourgeoise dotée de privilèges et de chartes dès la fin du Moyen-Age, siège du duché de Brabant à la Renaissance, ville de commandement des princes qui administraient les Pays-Bas pour le compte des rois d'Espagne, puis des empereurs d'Autriche, aux 17e et 18e siècles. C'est cette tradition qui a façonné non seulement la morphologie de son centre historique, mais aussi la culture de ses habitants, et que certains d'entre eux refusent d'oublier, quelles que soient les balafres et les outrages du temps.

Does acclimation at higher temperatures affect the locomotor performance of one of the southernmost reptiles in the world?

Publisher: name: Acta Herpetologica
Year: 2012

description: When an animal in the laboratory experiences a change in temperature, physiological processes are affected but they stabilize under the new temperature condition over a few weeks by a process of phenotypic plasticity called acclimation, but whether an organism can acclimate or not depends on the trait and the taxon. Liolaemus sarmientoi is one of the southernmost reptiles in the world, inhabiting the extreme and arid environment of Patagonia, Argentina, characterised by great seasonal climatic variation and cold air temperatures throughout the year (mean air temperature of 8 °C; ranging from 1.2 to 14.1 °C). However, these lizards prefer body temperatures in the laboratory ranging from 26.3 to 37.8 °C (mean Tpref = 34.4 ± 0.28 °C), temperatures that they rarely achieve in nature. Herein, we explore the effects of thermal acclimation on performance of L. sarmientoi at a temperature higher than their mean natural environmental temperature during their activity period (austral spring-summer). We analysed the speed in sprint and long runs at medium and high temperatures in the field and again after a period of acclimation of 20 days at 21 °C. Acclimation to higher and constant temperature resulted in a decrease in running speed in both long and sprint runs, suggesting potentially negative effects for natural populations if environmental temperature increases.

Alternative methods for increasing physical activity in the treatment of peripheral artery disease: low-pain exercise and breaking up sitting time
Creators: name: Perks, Jemma L.
Publisher: name: University of Leicester
Year: 2023
Subjects: Uncategorized

description: Background: PAD is a cardiovascular disease caused by atherosclerosis, resulting from risk factors such as low levels of physical activity and diabetes. High-pain structured exercise is part of best medical therapy in this population, leading to improved physical function. Additional methods of increasing physical activity such as breaking up sitting time, and low-pain structured exercise, warrant investigation. Aims: Firstly; to quantify differences in physical activity, and physical function, in people with type 2 diabetes (T2D) with and without PAD; secondly to determine the effect of high-pain versus low-pain structured exercise on walking ability (physical function) in people with PAD, and thirdly; to determine the efficacy of a personalised activity plan for breaking up sitting time in people with PAD, to reduce time spent sitting and improve walking ability. Key findings: A cross-sectional analysis revealed that the presence of PAD in T2D may have detrimental effects on physical activity and physical function. Some differences in physical activity and physical function may be related to sociodemographic and clinical differences. A network meta-analysis confirmed strong evidence in support of structured high-pain exercise, and emerging novel evidence in support of structured low-pain exercise, to improve walking ability in people with PAD. Finally, using a single-arm trial, an 8 week personalised activity plan to break up sitting time significantly improved walking ability and reduced time spent sitting in people with PAD. Conclusions: The presence of PAD in T2D may be detrimental to physical activity and physical function. The use of breaking up sitting time, and low-pain structured exercise, are novel treatments and may be suitable alternatives in the treatment of PAD. Large scale RCT’s are warranted to support these findings.

Habitat selection of two sympatric species of Ameiva in East Costa Rica

name: Gómez, Ramón
Publisher: name: Acta Herpetologica
Year: 2012

description: Identifying the differences in habitat use for sympatric species is important for understanding the species preferences and the limits of population distribution. We studied the differences in the habitat use of two understudied sympatric species of Ameiva (A. festiva and A. quadrilineata) in a natural reserve of the Caribbean coast of Coast Rica. Ameiva quadrilineata showed a more restrictive habitat use pattern than A. festiva. A. quadrilineata’s smaller body size may be one of the factors limiting its habitat range. Both species showed higher density in regenerated forests, while A. quadrilineata was never found in swamp forests. The air temperature and the meteorological condition at the moment of the survey also influenced the occurrence of the A. quadrilineata, while the juveniles of A. festiva were only affected by the meteorological condition. None of the studied variables seemed to affect the occurrence of A. festiva adults. The results of this study can be useful to evaluate possible changes in the species distribution patterns as a consequence of direct (i.e., deforestation) or indirect (i.e., climate change) human activities in the distribution area of these species.

description: We present a one-step scheme to construct the controlled-phase gate deterministically on remote transmon qutrits coupled to different resonators connected by a superconducting transmission line for an universal distributed quantum computing. Different from previous works on remote superconducting qubits, the present gate is implemented with coherent evolutions of the entire system in the all-resonance regime assisted by the dark photons to robust against the transmission line loss, which allows the possibility of the complex designation of a long-length transmission line to link lots of circuit QEDs. The length of the transmission line can reach the scale of several meters, which makes our scheme is suitable for the large-scale distributed quantum computing. This gate is a fast quantum entangling operation with a high fidelity of about 99%. Compare with previous works in other quantum systems for a distributed quantum computing, under the all-resonance regime, the present proposal does not require classical pulses and ancillary qubits, which relaxes the difficulty of its implementation largely.

description: We used skeletochronology to assess the age structure, body size and sexual maturity in two populations of Liolaemus pictus argentinus from San Carlos de Bariloche, Argentina. The species occupies a wide altitudinal range within the Patagonian Lake District which enabled us to choose populations from two climatic extremes: 771 m a.s.l. and 1615-1769 m a.s.l. Age of sexual maturity in both populations of L. p. argentinus is achieved with a minimum body size of 49 mm. However, at the high-altitude site, lizards matured between the ages of three to six years and had a lifespan of eight years limiting some individual’s reproductive life to only two years. Lizards from the low-altitude site achieved maturity at the age of four and lived until the age of nine years old. Despite the environmental variations between sites populations’ growth curves’ patterns were similar represented by a rapid initial growth rate of 10.3 mm/year in youngest juvenile which slowed considerably to 4.9 mm/year after attaining sexual maturity, as energy is reallocated towards reproduction, to finally grow at a rate of 0.1 mm/year in the oldest adults. Present results show intraspecific differences in L. pictus, whether it results from adaptive polymorphism or physiological plasticity remains uncertain.

description: Trophic niche of the Italian wall lizard was studied at three different sites in Tuscany (central northern Italy), two along the Mediterranean sea, one inland. Fecal pellet analysis was carried out on 71 pellets (37 of male and 34 of female adult lizards), accounting on the whole for 184 prey items. Coleoptera, Hymenoptera (ants), Araneae and Gastropoda were the most represented taxa (numerical abundance of ca 22, 7, 7, 6% respectively). We found Brillouin diversity index similar in females and in males, with a marked overlap between sexes, but differences in niche overlapping among localities. Diet spectrum was quite different with that found in other central Italy localities, in the Tuscan Archipelago, or in areas where P. siculus has recently introduced. Our study confirms the opportunistic pattern and adaptability of this lizard species, and increases the range of sampled localities within the species’ range.

description: Polydactyly is a fairly frequent phenomenon in tetrapod populations, but it is relatively rare in reptiles. Here we report the occurrence of polydactyly in a random sample of the Tyrrhenian wall lizard (Podarcis tiliguerta) from Sardinia. In the locality of Siniscola (NE Sardinia), we found two polydactylous female lizards, one of which showed polydactyly in one and the other in both hind limbs. This observation constitutes, to the best of our knowledge, the highest frequency of polydactyly ever reported in a single lizard population (4.54%). While providing a direct explanation for polydactyly is complicated, the genetic data available show that the two polydactylous individuals are not direct siblings, excluding the hypothesis of direct maternal inheritance of this condition.

description: The Apennine Yellow-bellied toad Bombina variegata pachypus, a small anuran endemic to peninsular Italy, has been declining throughout its range over the last 30 years. Although mortality by chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis, was first reported for the species in 2004, its role in the decline has not yet been assessed. Between 2011 and 2012 we sampled eight populations of B. v. pachypus in Liguria, northern Italy, swabbing 86 and 143 individuals respectively, corresponding to between 24 and 80% of the estimated individuals within each population. We did not detect chytrid in any the samples collected. For the three largest populations in the region, we can rule out infections of prevalence greater than 10% with at least 98% confidence. Research at a larger scale is urgently needed to clarify the role of B. dendrobatidis in the decline of this and other amphibians in Italy.

On Non-Generic Finite Subgroups of Exceptional Algebraic Groups

Subjects: subject: Group Theory (math.GR)

description: The study of finite subgroups of a simple algebraic group $G$ reduces in a sense to those which are almost simple. If an almost simple subgroup of $G$ has a socle which is not isomorphic to a group of Lie type in the underlying characteristic of $G$, then the subgroup is called non-generic. This paper considers non-generic subgroups of simple algebraic groups of exceptional type in arbitrary characteristic. A finite subgroup is called Lie primitive if it lies in no proper subgroup of positive dimension. We prove here that many non-generic subgroup types, including the alternating and symmetric groups $\text{Alt}_{n}$, $\text{Sym}_{n}$ for $n \ge 10$, do not occur as Lie primitive subgroups of an exceptional algebraic group. A subgroup of $G$ is called $G$-completely reducible if, whenever it lies in a parabolic subgroup of $G$, it lies in a conjugate of the corresponding Levi factor. Here, we derive a fairly short list of possible isomorphism types of non-$G$-completely reducible, non-generic simple subgroups. As an intermediate result, for each simply connected $G$ of exceptional type, and each non-generic finite simple group $H$ which embeds into $G/Z(G)$, we derive a set of feasible characters, which restrict the possible composition factors of $V \downarrow S$, whenever $S$ is a subgroup of $G$ with image $H$ in $G/Z(G)$, and $V$ is either the Lie algebra of $G$ or a non-trivial Weyl module for $G$ of least dimension. This has implications for the subgroup structure of the finite groups of exceptional Lie type. For instance, we show that for $n \ge 10$, $\text{Alt}_n$ and $\text{Sym}_n$, as well as numerous other almost simple groups, cannot occur as a maximal subgroup of an almost simple group whose socle is a finite simple group of exceptional Lie type.

description: Objectives: Three informationists were integrated with an NIH R01-funded research team for two years on an NLM Administrative Supplement for Informationist Services from 2014 to 2016. What impacts, implicit and explicit, have resulted from this partnership? What recommendations can this team make about research services generally and specifically to this library? What suggestions can this team make for this grant program going forward? Methods: Prior informationist awardees supported by National Library of Medicine administrative supplements have reported on their experiences through webinars, publications, grant reports, and posters. This collective wisdom was valuable in planning for the evaluation portion of this libraryâ€™s administrative supplement. This team used a logic model; researcher and informationist interviews; notes from more than 30 team meetings and debriefings; field notes and memos; and impact tablesÂ (positive and negative impacts on the R01 research team/their research and on the informationists/library) to collect data. Analytical methods included 1) an independent review of these data by two librarians to compile a master list of key themes and 2) a second independent review by these librarians for impact evidence (direct quotes, observations, and inferences).Â Broad categories that have emerged to date include impacts resulting from informationist participation; challenges; successes; replicable service ideas; how researchers work; and lessons learned (e.g., for informationists, for the NLM grant program). This poster will summarize these methods, findings, and recommendations. Results: The use of a logic model at the beginning of the grant and ongoing updates of the impact tables throughout aided tracking and reporting of progress and impacts. The added decision to collect qualitative data, the act of collecting it, and first-pass analysis of those data also helped the team a) demonstrate the value of embedded informationists, b) understand researchers™ work context, and c) identify librarians™ professional development needs. Understanding researchers™ work contexts helps librarians target not only resources and services but how and when to get researchers™ attention. In order to support researchers more effectively, librarians in liaison roles need expanded knowledge of the local research infrastructure as well as knowledge of local and major granting agencies™ funding mechanisms, processes, timelines, jargon, and staffing. Conclusion: The use of varied evaluation techniques, including a logic model, qualitative methods, and keeping detailed impact tables throughout the life of an NLM Administrative Supplement for Informationist Services is a worthwhile strategy for demonstrating the impact of informationists embedded in research teams.
Novel, non-invasive method for distinguishing the individuals of the fire salamander (Salamandra salamandra) in capture-mark-recapture studies

description: Recently we started implementing a highly efficient, non-invasive method of direct individual marking (i.e., typifying) in a population study of the fire salamander, Salamandra salamandra. Our technique is based on the unique alphanumeric code for every individual, generated upon the numbers of openings of repellent/toxic skin glands in the yellow areas of the selected regions of the body. This code was proved reliable in the sample of 159 individuals from two separate populations and enabled easy and quick recognition of recaptured animals. The proposed method is inexpensive, easily applicable in the field, involves minimum stress for the animals and does not affect their behaviour and the possibility of repeated captures of “marked” (i.e., coded) individuals. It is particularly suitable for dense populations.

description: La lucertola ocellata Timon lepidus (Daudin, 1802) è diffuso nella penisola iberica, nel sud della Francia e nella Liguria occidentale e centrale (Mateo e Cheylan, 1997), regione che costituisce il limite orientale della sua distribuzione (Camerano, 1885; Bruno, 1982; Ferri et al., 1991). In Italia, l’areale della specie è frammentato (doria e Salvidio, 1994) con popolazioni isolate, spesso minacciate dalla continua alterazione degli habitat idonei e in particolare dagli incendi e dalla continua edificazione delle aree costiere (Salvidio et al., 2004). L’interesse biogeografico e conservazionistico di queste popolazioni al limite di areale è pertanto evidente, ma i dati sulla biologia di questo lacertide in Italia sono ancora scarsi e le informazioni riportate da Corti e Lo Cascio (1999) si riferiscono solo alle popolazioni spagnole e francesi.

description: Sparse representations using data dictionaries provide an efficient model particularly for signals that do not enjoy alternate analytic sparsifying transformations. However, solving inverse problems with sparsifying dictionaries can be computationally expensive, especially when the dictionary under consideration has a large number of atoms. In this paper, we incorporate additional structure on to dictionary-based sparse representations for visual signals to enable speedups when solving sparse approximation problems. The specific structure that we endow onto sparse models is that of a multi-scale modeling where the sparse representation at each scale is constrained by the sparse representation at coarser scales. We show that this cross-scale predictive model delivers significant speedups, often in the range of 10-60$\times$, with little loss in accuracy for linear inverse problems associated with images, videos, and light fields.

In this study, we investigated the reproductive output patterns of the species during the breeding periods of 2012 and 2013. Our results showed that clutch size and total clutch volume increased with maternal body size. However, no significant correlation between egg number and egg size was observed, which suggested that the tradeoff between offspring number and size in this species was lack.

description: In this outline of a program, based on rigorous renormalization group theory, we introduce new definitions which allow one to formulate precise mathematical conjectures related to conformal invariance as studied by physicists in the area known as higher-dimensional conformal bootstrap which has developed at a breathtaking pace over the last few years. We also explore a second theme, intimately tied to conformal invariance for random distributions, which can be construed as a search for very general first and second-quantized Kolmogorov-Chentsov Theorems. First-quantized refers to regularity of sample paths. Second-quantized refers to regularity of generalized functionals or Hida distributions and relates to the operator product expansion. We formulate this program in both the Archimedean and $p$-adic situations. Indeed, the study of conformal field theory and its connections with probability provides a golden opportunity where $p$-adic analysis can lead the way towards a better understanding of open problems in the Archimedean setting. Finally, we present a summary of progress made on a $p$-adic hierarchical model and point out possible connections to number theory. Parts of this article were presented in author's talk at the 6th International Conference on $p$-adic Mathematical Physics and its Applications, Mexico 2017.

description: “Operation Car Wash” was a judicial inquiry in Brazil between 2014 and 2021. It investigated corruption; however, it targeted disproportionately leftist Workers’ Party, removing it from government and facilitating the election of far-right Jair Bolsonaro. During fourteen years in the presidency, the Workers’ Party somehow disturbed neoliberalism, focusing on welfare, affirmative measures and a foreign policy that did not prioritise the United States. The US has been responsible for the overthrow of progressive political leaders on multiple occasions. This thesis argues the US interfered again, allying with Brazil’s dominant classes to restore class power and reinforce hegemony in Latin America.

description: Noise-induced hearing loss (NIHL) is the result of exposure to sounds that are too loud in our environment, and it is entirely preventable. A CDC study in 2012 estimated that as many as 24 percent of adults have features of NIHL. Hearing conservation programs (HCPs) in workplace environments exist in order to protect workers and educate them on the effects of NIHL. These HCPs work to reduce worker’s exposure to these loud sounds that can cause permanent hearing loss. An estimated 5.2 million children have NIHL in one or both ears. Increased mp3 player use has led to a growth in this population. NIHL can impact children in the same way that it impacts adults, but there is an additional concern of educational impact. The impact of hearing loss on academic performance is well documented and as there is rise in NIHL among school age children, there is a push to educate and protect this vulnerable population. When poor classroom acoustics are also taken in to consideration, the concern becomes even larger. Previous research has demonstrated that adult HCPs are effective. Fewer hearing conservation programs exist for children, and the effectiveness of them is not well known.

description: Mitigating methane (CH4) emissions is of uttermost importance to meet the targets of the Paris Agreement as the second-most important greenhouse gas in terms of radiative forcing. The atmospheric CH4 burden is rising, and has been doing so since the industrial times predominantly due to human activities. Novel airborne and space-based instruments have the potential to address the challenges towards detecting and quantifying localised emissions. The ultimate goal of this thesis is to use these state-of-art remote sensing measurements to improve inventories currently informed by modelled and process-based data. CH4 point source emissions require a high spatial resolution to distinguish between different sources and a high spectral resolution to characterise the CH4 component of the atmosphere. This thesis uses the hyperspectral imager AisaFENIX, with a spectral range capable of measuring CH4 in the SWIR around 2300 nm and a spatial resolution of about 2.5 m2, in the first tailored flight campaign with the BAS Twin Otter aircraft over UK CH4 point sources. Based on a fast data-driven retrieval algorithm to infer atmospheric concentrations of CH4 from spectroscopic measurements, it successfully explores the detection limits using real and simulated CH4 plumes. The detection limit suggests that assuming a constant rate of emissions throughout the year, even the highest reported UK emitter for 2018 (Drax Power Station) would not be detected. The retrieval has applications beyond the flight campaign and can be easily adapted for the next generation of hyperspectral satellites. This thesis also investigates the use of the Sentinel-5P satellite, with unprecedented daily global coverage and spatial resolution of around 7 km2, to quantify CH4 emissions over areas with limited observations. By identifying persistent CH4 enhancements, this thesis has successfully quantified emissions in South African coal mines and oil and gas facilities in Egypt. The estimates in this thesis for South Africa are in good agreement with the EDGAR v4.3.2 inventory, which underestimates emissions in Egypt by a third probably due to uncaptured fugitive emissions.

description: We develop a theory of eventually positive $C_0$-semigroups on Banach lattices, that is, of semigroups for which, for every positive initial value, the solution of the corresponding Cauchy problem becomes positive for large times. We give characterisations of such semigroups by means of spectral and resolvent properties of the corresponding generators, complementing existing results on spaces of continuous functions. This enables us to treat a range of new examples including the square of the Laplacian with Dirichlet boundary conditions, the bi-Laplacian on $L^p$-spaces, the Dirichlet-to-Neumann operator on $L^2$ and the Laplacian with non-local boundary conditions on $L^2$ within the one unified theory. We also introduce and analyse a weaker notion of eventual positivity which we call "asymptotic positivity", where trajectories associated with positive initial data converge to the positive cone in the Banach lattice as $t \to \infty$. This allows us to discuss further examples which do not fall within the above-mentioned framework, among them a network flow with non-positive mass transition and a certain delay differential equation.

description: We describe two psychometric approaches undertaken to generate 8 subscales from the 40 Markers of Adulthood (MoA) items in the EAMMI survey. First, we describe the inductive approach, drawing from empirical analyses of 20 of the items. Second we describe the deductive approach toward scale construction. In addition to describing the processes of scale construction, we also describe the attributes and psychometric properties of the scales derived. Finally, we assess the inter-construct validity of inductive vis-a-vis deductive approaches, finding high correlations between the two sets of measures. In addition, we draw from use of the 40 MoA items in the extant literature to provide a comparative analyses of the EAMMI items. We find that, despite divergent 'styles' of psychometric reasoning, both approaches are consistent with the strengths and he challenges of constructing scales in the literature. We conclude with a review of the lessons learned. Included in he appendix are results of by the first author of a replication and extension of principal components analysis.

description: A multiple-scale perturbation analysis is presented to analyse the two-dimensional concentration distribution of passive contaminant released in an incompressible viscous fluid flowing between two parallel plates filled with a porous medium. The flow is driven by the combined effect of the upper plate oscillation in its own plane moving with a constant velocity, and the periodic pressure gradient. Mei’s homogenization technique is used to find the concentration distribution up to third order, complemented with the dispersion coefficients for four different situations, namely, steady, pulsatile, oscillatory and the combined effect of all these. We observe that when the flow is under the combined effect of wall oscillation and pressure pulsation, then the respective frequency (Womersley number) and amplitude parameters oppose each other while influencing the dispersion coefficient. Our analysis reveals that for a fixed amplitude of oscillation and pulsation, the frequency of pressure pulsation has a stronger effect on the dispersion coefficient compared with the wall oscillation. On the other hand, when the Womersley number is kept fixed, amplitude of the wall oscillation dominates the pressure pulsation. This behaviour is more prominent for higher values of the Darcy number. The transverse concentration distribution and its dependency on porous medium parameters are also discussed in detail.

description: In the 1970's, Serre exploited congruences between $q$-expansion coefficients of Eisenstein series to produce $p$-adic families of Eisenstein series and, in turn, $p$-adic zeta functions. Partly through integration with more recent machinery, including Katz's approach to $p$-adic differential operators, his strategy has influenced four decades of developments. Prior papers employing Katz's and Serre's ideas exploiting differential operators and congruences to produce families of automorphic forms rely crucially on $q$-expansions of automorphic forms. The overarching goal of the present paper is to adapt the strategy to automorphic forms on unitary groups, which lack $q$-expansions when the signature is of the form $(a, b)$, $a\neq b$. In particular, this paper completely removes the restrictions on the signature present in prior work. As intermediate steps, we achieve two key objectives. First, partly by carefully analyzing the action of the Young symmetrizer on Serre-Tate expansions, we explicitly describe the action of differential operators on the Serre-Tate expansions of automorphic forms on unitary groups of arbitrary signature. As a direct consequence, for each unitary group, we obtain congruences and families analogous to those studied by Katz and Serre. Second, via a novel lifting argument, we construct a $p$-adic measure taking values in the space of $p$-adic automorphic forms on unitary groups of any prescribed signature. We relate the values of this measure to an explicit $p$-adic family of Eisenstein series. One application of our results is to the recently completed construction of $p$-adic $L$-functions for unitary groups by the first named author, Harris, Li, and Skinner.

Intraspecific variation in erythrocyte sizes among populations of Hypsiboas cordobas (Anura: Hylidae)

description: We studied the morphology and size of erythrocytes of H. cordobae, and analysed the geographic variation of this character along the distribution of the species, in relation to the latitudinal and altitudinal distances. Erythrocyte shape of the H. cordobae is ellipsoidal and the nuclei are also ellipsoidal and centrally oriented. Erythrocyte and nuclear size showed significant differences among populations, with the highest mean size corresponding to the population of Achiras (low altitude site) and the lowest mean size to Los Linderos (high altitude site). There was no significant relationship between the latitude of each population and the both erythrocyte and nuclear size. The altitudinal variation in erythrocyte cell size may be attributable to the surface available for gas exchange; a small erythrocyte offers a possibility of greater rate of exchange than a larger one. Our results are consistent with studies of other amphibians, where intraspecific comparisons of populations at different altitudes show that individuals at higher altitudes are characterized by smaller erythrocytes.

description: The theory of speech prosody that has been developed in Articulatory Phonology predicts a local slowing of articulator movements at the boundaries of prosodic domains. The goal of the present study is to determine whether this local slowing produces a change in the slope of Fitts' law that is predicted by a theoretically-derived relation between a model parameter that controls articulator speed (i.e., gestural stiffness) and the slope of Fitts' law. The study breaks new ground by testing for a theoretically predicted prosodic influence on Fitts' Law in speech production. Establishing this connection between speech prosody and Fitts' law would indicate a connection between the sound system of language and information throughput in the motor system.
