description: In this paper, we explicitly calculate the aether-like corrections for the electromagnetic field in the case when the space-time involves an extra compact spatial dimension besides of usual four dimensions. Our methodology is based on an explicit summation over the Kaluza-Klein tower of fields which turns out to be no more difficult than the finite-temperature calculations. We found some new terms which can be treated as certain five-dimensional generalizations of the aether-like terms $κ^{mnpq}F_{mn}F_{pq}$ and $\barψc^{mn}γ_m\partial_nψ$ which in four dimensions are treated as important ingredients of the Lorentz-breaking extension of the standard model. We have shown that these new terms become to dominate in the limit where the extra dimension is very small, allowing us to suggest that there will be essential modifications of quantum corrections if our space indeed has a small extra spatial dimension. Moreover, we have shown that in the CPT-even case we have extra new particles as a consequence of the extra dimension.

description: Let $C$ be a $4$-cover of an elliptic curve $E$, written as a quadric intersection in $\mathbb{P}^3$. Let $E'$ be another elliptic curve with $4$-torsion isomorphic to that of $E$. We show how to write down the $4$-cover $C'$ of $E'$ with the property that $C$ and $C'$ are represented by the same cohomology class on the $4$-torsion. In fact we give equations for $C'$ as a curve of degree $8$ in $\mathbb{P}^5$. We also study the K3-surfaces fibred by the curves $C'$ as we vary $E'$. In particular we show how to write down models for these surfaces as complete intersections of quadrics in $\mathbb{P}^5$ with exactly $16$ singular points. This allows us to give examples of elliptic curves over $\mathbb{Q}$ that have elements of order $4$ in their Tate-Shafarevich group that are not visible in a principally polarized abelian surface.

description: Celtodoryx ciocalyptoides is a Pacific sponge recorded for the first time as invasive in Europe (south Brittany, France) in 1996, then in 2005 (The Netherlands) and 2014 (eastern English Channel), likely in relation with aquaculture activities. It was observed by amateur divers in Arcachon Bay, Hossegor Lake (SW coast of France) and Thau Lagoon (French Mediterranean), but our study formally confirms its presence in the former two locations. Among the associated species, there was another non-indigenous species in both sites, the spionid polychaete Polydora colonia. Described from USA Atlantic coasts and later found in the Mediterranean, this worm seems to live exclusively in association with C. ciocalyptoides in our study sites. We suggest that this unlikely association between a Pacific sponge and a Western Atlantic worm, likely distributed along European coasts by oyster transfers, is probably more widespread than currently known.

description: Despite our extensive knowledge of biophysical properties of neurons, there is no commonly accepted algorithmic theory of neuronal function. Here we explore the hypothesis that single-layer neuronal networks perform online symmetric nonnegative matrix factorization (SNMF) of the similarity matrix of the streamed data. By starting with the SNMF cost function we derive an online algorithm, which can be implemented by a biologically plausible network with local learning rules. We demonstrate that such network performs soft clustering of the data as well as sparse feature discovery. The derived algorithm replicates many known aspects of sensory anatomy and biophysical properties of neurons including unipolar nature of neuronal activity and synaptic weights, local synaptic plasticity rules and the dependence of learning rate on cumulative neuronal activity. Thus, we make a step towards an algorithmic theory of neuronal function, which should facilitate large-scale neural circuit simulations and biologically inspired artificial intelligence.

description: Longitudinal studies of a binary outcome are common in the health, social, and behavioral sciences. In general, a feature of random effects logistic regression models for longitudinal binary data is that the marginal functional form, when integrated over the distribution of the random effects, is no longer of logistic form. Recently, Wang and Louis (2003) proposed a random intercept model in the clustered binary data setting where the marginal model has a logistic form. An acknowledged limitation of their model is that it allows only a single random effect that varies from cluster to cluster. In this paper, we propose a modification of their model to handle longitudinal data, allowing separate, but correlated, random intercepts at each measurement occasion. The proposed model allows for a flexible correlation structure among the random intercepts, where the correlations can be interpreted in terms of Kendall’s τ. For example, the marginal correlations among the repeated binary outcomes can decline with increasing time separation, while the model retains the property of having matching conditional and marginal logit link functions. Finally, the proposed method is used to analyze data from a longitudinal study designed to monitor cardiac abnormalities in children born to HIV-infected women.

description: In the event-related functional magnetic resonance imaging (fMRI) data analysis, there is an extensive interest in accurately and robustly estimating the hemodynamic response function (HRF) and its associated statistics (e.g., the magnitude and duration of the activation). Most methods to date are developed in the time domain and they have utilized almost exclusively the temporal information of fMRI data without accounting for the spatial information. The aim of this paper is to develop a multiscale adaptive smoothing model (MASM) in the frequency domain by integrating the spatial and temporal information to adaptively and accurately estimate HRFs pertaining to each stimulus sequence across all voxels in a three-dimensional (3D) volume. We use two sets of simulation studies and a real data set to examine the finite sample performance of MASM in estimating HRFs. Our real and simulated data analyses confirm that MASM outperforms several other state-of-art methods, such as the smooth finite impulse response (sFIR) model.

A Large Deviations Approach to Secure Lossy Compression

Year: 2015
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: We consider a Shannon cipher system for memoryless sources, in which distortion is allowed at the legitimate decoder. The source is compressed using a rate distortion code secured by a shared key, which satisfies a constraint on the compression rate, as well as a constraint on the exponential rate of the excess-distortion probability at the legitimate decoder. Secrecy is measured by the exponential rate of the exiguous-distortion probability at the eavesdropper, rather than by the traditional measure of equivocation. We define the perfect secrecy exponent as the maximal exiguous-distortion exponent achievable when the key rate is unlimited. Under limited key rate, we prove that the maximal achievable exiguous-distortion exponent is equal to the minimum between the average key rate and the perfect secrecy exponent, for a fairly general class of variable key rate codes.

description: We show that the Burkhardt quartic threefold is rational over any field of characteristic distinct from 3. We compute its zeta function over finite fields. We realize one of its moduli interpretations explicitly by determining a model for the universal genus 2 curve over it, as a double cover of the projective line. We show that the j-planes in the Burkhardt quartic mark the order 3 subgroups on the Abelian varieties it parametrizes, and that the Hesse pencil on a j-plane gives rise to the universal curve as a discriminant of a cubic genus one cover.

description: A possible solution of the well known paradox of chiral molecules is based on the idea of spontaneous symmetry breaking. At low pressure the molecules are delocalized between the two minima of a given molecular potential while at higher pressure they become localized in one minimum due to the intermolecular dipole-dipole interactions. Evidence for such a phase transition is provided by measurements of the inversion spectrum of ammonia and deuterated ammonia at different pressures. In particular, at pressure greater than a critical value no inversion line is observed. These data are well accounted for by a model previously developed and recently extended to mixtures. In the present paper, we discuss the variation of the critical pressure in binary mixtures as a function of the fractions of the constituents.

description: Diffusion tensor imaging provides important information on tissue structure and orientation of fiber tracts in brain white matter in vivo. It results in diffusion tensors, which are 3×3 symmetric positive definite (SPD) matrices, along fiber bundles. This paper develops a functional data analysis framework to model diffusion tensors along fiber tracts as functional data in a Riemannian manifold with a set of covariates of interest, such as age and gender. We propose a statistical model with varying coefficient functions to characterize the dynamic association between functional SPD matrix-valued responses and covariates. We calculate weighted least squares estimators of the varying coefficient functions for the Log-Euclidean metric in the space of SPD matrices. We also develop a global test statistic to test specific hypotheses about these coefficient functions and construct their simultaneous confidence bands. Simulated data are further used to examine the finite sample performance of the estimated varying co-efficient functions. We apply our model to study potential gender differences and find a statistically significant aspect of the development of diffusion tensors along the right internal capsule tract in a clinical study of neurodevelopment.

description: In order to highlight the variation of the form due to the presence of different ecological factors, we investigated in this paper the morphological variation between and within the two marine species Salaria basilisca and S. pavo. This study was based on two approaches, the Truss network and the geometric morphometric and involved specimens of both species divided into marine and lagoon samples. The two approaches yielded complementary results showing clear morphological discrimination of the two species Thus, S. basilisca is distinguished by a higher depth and length as well as a higher head with a compressed snout compared to S. pavo which has a shortened body, a lower head and a slightly stretched snout. At an intraspecific scale, both approaches showed a discrimination of marine and lagoon samples for both species: marine samples tend to have an elongated, shallower body with a small head while lagoon samples are distinguished by a shorter, deeper body and a tall head.

description: Ambulatory cardiovascular (CV) measurements provide valuable insights into individuals' health conditions in “real-life,” everyday settings. Current methods of modeling ambulatory CV data do not consider the dynamic characteristics of the full data set and their relationships with covariates such as caffeine use and stress. We propose a stochastic differential equation (SDE) in the form of a dual nonlinear Ornstein-Uhlenbeck (OU) model with person-specific covariates to capture the morning surge and nighttime dipping dynamics of ambulatory CV data. To circumvent the data analytic constraint that empirical measurements are typically collected at irregular and much larger time intervals than those evaluated in simulation studies of SDEs, we adopt a Bayesian approach with a regularized Brownian Bridge sampler (RBBS) and an efficient multiresolution (MR) algorithm to fit the proposed SDE. The MR algorithm can produce more efficient MCMC samples that is crucial for valid parameter estimation and inference. Using this model and algorithm to data from the Duke Behavioral Investigation of Hypertension Study, results indicate that age, caffeine intake, gender and race have effects on distinct dynamic characteristics of the participants' CV trajectories.

description: POSTER presented at NANOINNOVATION 2018 The synthesis of colloidal photo-luminescent semiconductor quantum dots (QDs), belonging to II-VI groups, even from single source precursors is presented. Since three decades their synthesis has been pursued implementing new and easier synthetic conditions that standardize their production. In this work is reported the production of luminescent of CdS QDs in a polymeric film induced by laser processing (www.miledi-h2020.eu/). A film of PMMA doped with two types of precursors (cadmium xanthates) is irradiated with an UV laser source with different energy doses. The structured film will then be observed with confocal fluorescent microscope. The interesting results shows that the two different xanthates display a different behaviour under the laser source even if their absorption spectrum is similar. The second interesting result is that the effect of the laser is the production luminescent pattern only for certain fluences and that the same film treated with the temperature did not show any luminescent. These results points out the role of the laser light in the process of luminescent QDs growth that the temperature can’t activate.

description: The authors report the capture of a specimen of the red seabream Pagrus major (Temminck & Schlegel,1843) from the Syrian coast in the eastern Mediterranean Sea. The present specimen measured 214 mm in total length and weighed 169 g. It is the first record from the Syrian coast and the third from the eastern Mediterranean. It constitutes also the easternmost extension range of the species in this sea. P. major is a non-native species from the Mediterranean, introduced via sea farrming or released from aquariums. It is a highly adaptable to environmental changes in the wild, additionally it is an opportunistic feeder. The successfull establishment of a viable population of the species in the Mediterranean Sea cannot be totally ruled out.

description: The aim of this paper is to develop a Bayesian functional linear Cox regression model (BFLCRM) with both functional and scalar covariates. This new development is motivated by establishing the likelihood of conversion to Alzheimer’s disease (AD) in 346 patients with mild cognitive impairment (MCI) enrolled in the Alzheimer’s Disease Neuroimaging Initiative 1 (ADNI-1) and the early markers of conversion. These 346 MCI patients were followed over 48 months, with 161 MCI participants progressing to AD at 48 months. The functional linear Cox regression model was used to establish that functional covariates including hippocampus surface morphology and scalar covariates including brain MRI volumes, cognitive performance (ADAS-Cog), and APOE status can accurately predict time to onset of AD. Posterior computation proceeds via an efficient Markov chain Monte Carlo algorithm. A simulation study is performed to evaluate the finite sample performance of BFLCRM.

Dies ist quantitativ nur unzureichend gelungen. Es wird angenommen, daß vor allem die Einbindung eines solchen Verfahrens in politische Entscheidungsfindungsprozesse über tragfähige und transparente neue Strukturen die Motivation der Teilnehmer erhöhen und damit die Anwendbarkeit und die Qualität dieser Methode entscheidend verbessern könnte. Inhaltlich hat sich gezeigt, daß die Schnittstelle zwischen Forschung und klinischer Anwendung beziehungsweise klinischen Standards von allen Beteiligten, also von Forschern, Medizinern, Betroffenen, Politikern und Begleitforschern, als zentraler Aspekt in der Debatte um medizinische Innovation, ihren Beitrag zu neuen Therapien und ihrer gesellschaftlichen Akzeptanz gesehen wird. Die Bewertung neuer Therapiechancen darf nicht nur innerhalb eines medizinischen Paradigmas erfolgen, sondern muß darüber hinaus sowohl lebensweltliche Aspekte der zu Behandelnden als auch gesellschaftliche Ansprüche an die ethisch-soziale Akzeptierbarkeit zu befriedigen wissen. Die Ergebnisse dieses Online-Diskurses regen zum Nachdenken darüber an,wie man der Schnittstelle Forschung – Anwendung eine breitere Wissens- und Erfahrungsbasis zur Verfügung stellen kann. Grundsätzlich muß die Frage beleuchtet werden, inwieweit der zur Zeit weitgehend exklusiv kontrollierte Bereich der Anwendung von medizinischer Grundlagenforschung größerer Transparenz bedarf und wie diese erreicht werden könnte. Aufgrund dieser Überlegungen empfehlen wir den Ausbau von qualitativ hochwertigen Diskursverfahren zum besseren Verständnis der Interessenlandschaft.

description: NASA's Galaxy Evolution Explorer (GALEX) provided near- and far-UV observations for approximately 77 percent of the sky over a ten-year period; however, the data reduction pipeline initially only released single NUV and FUV images to the community. The recently released Python module gPhoton changes this, allowing calibrated time-series aperture photometry to be extracted easily from the raw GALEX data set. Here we use gPhoton to generate light curves for all hot subdwarf B (sdB) stars that were observed by GALEX, with the intention of identifying short-period, p-mode pulsations. We find that the spacecraft's short visit durations, uneven gaps between visits, and dither pattern make the detection of hot subdwarf pulsations difficult. Nonetheless, we detect UV variations in four previously known pulsating targets and report their UV pulsation amplitudes and frequencies. Additionally, we find that several other sdB targets not previously known to vary show promising signals in their periodograms. Using optical follow-up photometry with the Skynet Robotic Telescope Network, we confirm p-mode pulsations in one of these targets, LAMOST J082517.99+113106.3, and report it as the most recent addition to the sdBVr class of variable stars.

description: Baeolidia rieae Carmona, Pola, Gosliner & Cervera, 2014 was described based on a single specimen from the subtropical Amami-Oshima Island (SW Japan). In this study, we recorded B. rieae feeding on a zoantharian, Zoanthus sp., in an aquarium store in Barcelona (Spain). The morphological and molecular match from the original description corroborated its identification. We discuss the possible origin of the B. rieae in aquarium stores, its resistance to ordinary disinfection processes, the harm it may cause to commercial coral species, and how it might develop into an invasive species if it continues to be found in aquarium stores around the world without treating the problem properly. Finally, we describe for the first time the spawn of B. rieae and its eggs features, and provide new morphological and biological data.

description: Overall and spatiotemporal total length-weight relationships (LWR) were studied for the 116 fish composing of 107 osseous and 9 cartilaginous fish species collected by otter trawl in the shelf and upper slope of Gulf of Antalya in 2014-2015. Of the 89 abundant bony species, 38 species had isometric growth, 24 species positive allometry, and 27 species negative allometry. Growth type was significantly affected with the sample size. LWRs of osseous fish species which had their body condition factor CF ≤ 1 were significantly differentiated by factors region, season and depth, but none was for the fish having CF ≥ 1. The factorial differences were found in relation with the CF. The b values for the osseous fish decreased slightly with bottom depth from lower shelf to middle shelf. The highest b values occurred for the ubiquitous fish on the entire shelf while the a values increased. At greater depths, the b values shifted the allometry from the isometry to the negative allometry. Average b value of osseous fish was 2.962 ± 0.048 (isometric), and median was 2.992. LWRs of body widthweight of batoid fish showed a b value ≤ 3. Sexual dimorphism in the LWR occurred for 10 species.

description: Cardiometabolic diseases have substantially increased in China in the past 20 years and blood pressure is a primary modifiable risk factor. Using data from the China Health and Nutrition Survey we examine blood pressure trends in China from 1991 to 2009, with a concentration on age cohorts and urbanicity. Very large values of blood pressure are of interest, so we model the conditional quantile functions of systolic and diastolic blood pressure. This allows the covariate effects in the middle of the distribution to vary from those in the upper tail, the focal point of our analysis. We join the distributions of systolic and diastolic blood pressure using a copula, which permits the relationships between the covariates and the two responses to share information and enables probabilistic statements about systolic and diastolic blood pressure jointly. Our copula maintains the marginal distributions of the group quantile effects while accounting for within-subject dependence, enabling inference at the population and subject levels. Our population level regression effects change across quantile level, year, and blood pressure type, providing a rich environment for inference. To our knowledge, this is the first quantile function model to explicitly model within-subject autocorrelation and is the first quantile function approach that simultaneously models multivariate conditional response. We find that the association between high blood pressure and living in an urban area has evolved from positive to negative, with the strongest changes occurring in the upper tail. The increase in urbanization over the last twenty years coupled with the transition from the positive association between urbanization and blood pressure in earlier years to a more uniform association with urbanization suggests increasing blood pressure over time throughout China, even in less urbanized areas. Our methods are available in the R package BSquare.

description: A prediscretisation of numerical attributes which is required by some rule learning algorithms is a source of inefficiencies. This paper describes new rule tuning steps that aim to recover lost information in the discretisation and new pruning techniques that may further reduce the size of rule models and improve their accuracy. The proposed QCBA method was initially developed to postprocess quantitative attributes in models generated by the Classification based on associations (CBA) algorithm, but it can also be applied to the results of other rule learning approaches. We demonstrate the effectiveness on the postprocessing of models generated by five association rule classification algorithms (CBA, CMAR, CPAR, IDS, SBRL) and two first-order logic rule learners (FOIL2 and PRM). Benchmarks on 22 datasets from the UCI repository show smaller size and the overall best predictive performance for FOIL2+QCBA compared to all seven baselines. Postoptimised CBA models have a better predictive performance compared to the state-of-the-art rule learner CORELS in this benchmark. The article contains an ablation study for the individual postprocessing steps and a scalability analysis on the KDD'99 Anomaly detection dataset.

description: The effect of artificial structures on littoral communities is well characterized regarding abundance and species composition, but the alterations of the fitness or the reproductive performance of individual species remains less well known. We compared 276 specimens from two populations (one living on an artificial seawall and another on a natural rocky shore) of the locally dominant isopod Ischyromene lacazei based on their morphometric characteristics and growth pattern. The population dwelling on the artificial surface showed lower values for all the body dimensions. In both populations, growth pattern was negatively allometric concerning body length related to cephalic size and pleotelson width, and positively allometric for pereon and pleon lengths. Pereon of individuals from natural surface became proportionally larger with length and the difference was most remarkable with respect to width, since growth was negatively allometric in the population from the man-made surface and positively allometric on that from the natural one. Previous research related smaller body size with lower reproductive output and metabolic fitness in isopods, so it can be concluded that the population on the seawall was negatively affected by environmental condition. The cause of the difference in size was not identified, but might be related to a stronger water flow on the artificial surface.

description: Magnetic fields permeate the entire solar atmosphere weaving an extremely complex pattern on both local and global scales. In order to understand the nature of this tangled web of magnetic fields, its magnetic skeleton, which forms the boundaries between topologically distinct flux domains, may be determined. The magnetic skeleton consists of null points, separatrix surfaces, spines and separators. The skeleton is often used to clearly visualize key elements of the magnetic configuration, but parts of the skeleton are also locations where currents and waves may collect and dissipate. In this review, the nature of the magnetic skeleton on both global and local scales, over solar cycle time scales, is explained. The behaviour of wave pulses in the vicinity of both nulls and separators is discussed and so too is the formation of current layers and reconnection at the same features. Each of these processes leads to heating of the solar atmosphere, but collectively do they provide enough heat, spread over a wide enough area, to explain the energy losses throughout the solar atmosphere? Here, we consider this question for the three different solar regions: active regions, open-field regions and the quiet Sun. We find that the heating of active regions and open-field regions is highly unlikely to be due to reconnection or wave dissipation at topological features, but it is possible that these may play a role in the heating of the quiet Sun. In active regions, the absence of a complex topology may play an important role in allowing large energies to build up and then, subsequently, be explosively released in the form of a solar flare. Additionally, knowledge of the intricate boundaries of open-field regions (which the magnetic skeleton provides) could be very important in determining the main acceleration mechanism(s) of the solar wind.

description: Bivalve biomineralization is a highly complex and organized process, involving several molecular components identified in adults and larval stages. However, information is still scarce on the ontogeny of the organic matrix before calcification occurs. In this work, first shell formation was investigated in the mussel Mytilus galloprovincialis. The time course of organic matrix and CaCO3 deposition were followed at close times post fertilization (24, 26, 29, 32, 48 h) by calcofluor and calcein staining, respectively. Both components showed an exponential trend in growth, with a delay between organic matrix and CaCO3 deposition. mRNA levels of genes involved in matrix deposition (chitin synthase; tyrosinase-, TYR) and calcification (carbonic anhydrase; extrapallial protein) were quantified by qPCR at 24 and 48 hours post fertilization (hpf) with respect to eggs. All transcripts were upregulated across early development, with TYR showing highest mRNA levels from 24 hpf. TYR transcripts were closely associated with matrix deposition as shown by in situ hybridization. The involvement of tyrosinase activity was supported by data obtained with the enzyme inhibitor N-phenylthiourea. Our results underline the pivotal role of shell matrix in driving first CaCO3 deposition and the importance of tyrosinase in the formation of the first shell in M. galloprovincialis.

description: Zooplankton, collected in the Gulf of Tadjoura (Republic of Djibouti) during a cruise conducted to study the feeding behavior of the whale shark Rhincodon typus, was analyzed in terms of size class, abundance and species composition. This pilot study was aimed to better understand a possible correlation between mesozooplankton composition and size spectra, collected up to 10 m depth, and different feeding behaviour of R. typus. Our data indicate that holoplankton accounted from 93 to 100% of the total community, copepods represented more than 80% of the zooplanktonic community, with 14 copepod genera and 9 species. Our preliminary results suggest an association between suction feeding activity of R. typus and high abundance of small copepod species. Passive feeding was recorded during the lowest abundance of zooplankton, mainly composed by large chaetognaths and larvae of Belbezub hansenii belonging to the family of Luciferidae (Sergestids). These first results highlight the importance of analyzing the dimensional structure of mesozooplankton in the aggregation areas of whale shark and open up new and intriguing investigative approaches to better understand the biology of R. typus.

description: It was recently observed in \cite{Park:2014tia} that the holographic nature of gravity may hold a key to quantization of gravity. The so-called "holographic quantization" has been carried out in \cite{Park:2014noa,Park:2015ota} for Einstein gravity in a flat background. Generalizing the procedure to a curved background is the main goal of the present work. In particular, we consider the Einstein action expanded around a Schwarzschild background

description: Mangroves in the Omani waters form one of the major marine ecosystems in this part of the world, which are considered the home for diverse and economically important fish groupings. A scarcity of information exists concerning mangrove fish communities of Oman. In the present study, a documentation for the ichthyofauna of several chosen mangrove localities in Oman is given. Species abundance distribution curves were constructed and compared among studies. Overall, 177 fish species associated to Omani mangroves were identified. Among these there were 14 Chondrichthian species belonging to 5 families and 163 teleostean fish species included in 44 families. Fifteen fish families accounted for 80% or more of the relative abundance of all studies. In spite of the use of different fishing methods, common features arose for most of the mangrove fish assemblages. Perciformes was found to be the most dominant order, with 15, 34, 63 families, genera and species respectively. The remaining 20 orders showed having 1-3 families, 1-13 genera and 1-4 species. Blenniidae was the dominant family through the localities examined, with 10 genera and 19 species. Three community indices viz. Shannon-Weaver diversity index (H´), the evenness rate (J) and Jaccard similarity coefficient were applied to demonstrate species diversity of fish species in sampling areas and evenness to show similarities between localities examined. The result showed that the diversity of fishes in the eleven mangrove localities studied is high compared with the previous studies.

description: Double covers of a generic genus four curve C are in bijection with Cayley cubics containing the canonical model of C. The Prym variety associated to a double cover is a quadratic twist of the Jacobian of a genus three curve X. The curve X can be obtained by intersecting the dual of the corresponding Cayley cubic with the dual of the quadric containing C. We take this construction to its limit, studying all smooth degenerations and proving that the construction, with appropriate modifications, extends to the complement of a specific divisor in moduli. We work over an arbitrary field of characteristic different from two in order to facilitate arithmetic applications.

description: Maladaptive left ventricular hypertrophy (LVH) remains a prevalent and highly morbid condition associated with end-stage heart disease. Originally evaluated in the context of bone development, periostin is important in endocardial cushion formation and has recently been implicated in heart failure. Because of its potential role in cardiovascular development, we sought to establish the role of periostin after relief of pressure overload in animal and human models.
