title: Individual Variability of Effort-Based Training Prescriptions in Competitive Cyclists
Creators: name: O'Grady, Ciarán
name: LTD, Cadence Performance
Publisher: name: University of Kent
Year: 2021

description: The aim of this thesis was to investigate the use of effort-based intensity prescriptions as a method to reduce individual variability and the occurrence of training non-response. Specifically, this thesis explores the physiological, psychological, and metabolomic responses to the interaction of training duration and effort-based intensity on a single-bout basis, whole session basis, and during chronic training intervention. The first experimental study (Chapter 4) investigated individual variability during self- paced exercise bouts at a rating of perceived exertion (RPE) of either 9, 13, or 17, conducted for either 1, 4, or 8 min. The study found that effort-based intensity prescriptions at higher RPEs and shorter durations result in lower levels of individual variability. The second study (Chapter 5) investigated individual variability during maximal isoeffort training sessions in either short interval (30 sec), long interval (5 min), or continuous exercise matched for total training duration. Long intervals displayed lowest variability in both how the session was performed as well as physiological response compared to short intervals and continuous sessions. The third study (Chapter 6) comprised a 6-week training intervention using maximal isoeffort intensity prescriptions using short (30 sec) or long interval (5 min) session formats, as well as a control group. Whilst short intervals resulted in higher levels of individual variability, a greater training response was found following this session format compared to both the long interval and control groups. The fourth study (Chapter 7) investigated the metabolomic differences between session formats, and between variable and consistent responding participants from Chapter 5. Distinct metabolomic differences were found between all session formats, and key metabolites were found relating to energy turnover, purine metabolism, and amino acid metabolism based on whether individuals were consistent or variable in session performance. The fifth study (Chapter 8) investigated the chronic changes in the urinary metabolome following the training interventions as described in Chapter 6. Several metabolomic markers differentiated between training responders and non-responders, in addition to metabolites associated with increased MMP or V̇O2max across all training groups. The main finding of this thesis was that the use of higher intensity effort-based targets and shorter interval durations has potential in reducing the occurrence of non-response to training.

Cybersecurity-Enhanced GPS Spoofing Protection and Secure Information Transmission for UAVs
Creators: name: madhavaram, harshith
Publisher: name: Zenodo
Year: 2025

description: Unmanned Aerial Vehicles (UAVs) are increasingly vulnerable to cybersecurity threats such as GPS spoofing and communication breaches, necessitating advanced protection mechanisms. This paper presents a comprehensive framework integrating cybersecurity principles with AI and machine learning (ML) algorithms to enhance GPS spoofing protection and secure information transmission for UAVs. The framework employs cryptographic signal watermarking and AI-driven signal pattern analysis for real-time spoofing detection, supported by multi-factor signal validation through INS, geomagnetic sensors, and Visual SLAM. Secure communication is ensured via dynamic encryption, end-to-end data masking using homomorphic encryption, and neural network intrusion detection systems (IDS). Cyber-resilient pathways leverage behavior-based access control, distributed secure nodes, and AI-driven dynamic routing. Blockchain technology ensures GPS data integrity, while reinforcement learning (RL) models enable adaptive threat mitigation and self-learning security protocols. Incident response includes detailed cybersecurity logging, emergency navigation using onboard sensors, and encrypted mission data recall. This integrated approach provides robust, adaptive, and scalable solutions to address evolving cybersecurity challenges in UAV operations.

description: Based on characteristic amino acid sequences of kinases that phosphorylate the α subunit of eukaryotic translation initiation factor 2 (eIF2α kinases), degenerate oligonucleotide primers were constructed and used to polymerase chain reaction-amplify from genomic DNA of Neurospora crassa a sequence encoding part of a putative protein kinase. With this sequence an open reading frame was identified encoding a predicted polypeptide with juxtaposed eIF2α kinase and histidyl-tRNA synthetase- related domains. The 1646 amino acid sequence of this gene, called cpc-3, showed 35% positional identity over almost the entire sequence with GCN2 of yeast, which stimulates translation of the transcriptional activator of amino acid biosynthetic genes encoded by GCN4. Strains disrupted for cpc-3 were unable to induce increased transcription and derepression of amino acid biosynthetic enzymes in amino acid-deprived cells. The cpc-3 mutation did not affect the ability to up-regulate mRNA levels of cpc-1, encoding the GCN4 homologue and transcriptional activator of amino acid biosynthetic genes in N. crassa, but the mutation abolished the dramatic increase of CPC1 protein level in response to amino acid deprivation. These findings suggest that cpc- 3 is the functional homologue of GCN2, being required for increased translation of cpc-1 mRNA in amino acid-starved cells.

description: The Airy transform is an ideally suited tool to treat problem in classical and quantum optics. Even though the relevant mathematical aspects have been thoroughly investigated, the possibility it offers are wide and some aspects, as the link with special functions and polynomials, still contains unexplored aspects. In this note we will show that the so called Airy polynomials are essentially the third order Hermite polynomials. We will also prove that this identification opens the possibility of developing new conjectures on the properties of this family of polynomials.

description: These texts for SMOKEPENNY LYRICHORD HEAVENBRED; Or, Last year / By constant penetration / Encroaching on the reserve, a mock musical in progress, were produced by the code book of mining C. Algernon Moreing, Mining Engineer of the Montana Company, Limited, & the Mines Company, Limited, in tandem with ongoing research into the history and future of copper exploitation. Telegrams housed in Michigan Tech’s Copper Country Historical Collections clarify the various ways in which the telegraph was used to bridle the laborers who constituted the corporal infrastructure of that technology. Baroque code compounds store the brute links between bodies, metal, and the market, sometimes sanitizing, at other times proving grossly expressive. The acts focus on the great strike of 1913 at the Calumet & Hecla Mining Company in Michigan’s Keweenaw Peninsula—a bloody conflict provoked by the introduction of a hazardous economizing tool into the mines: the one-man compressed air drill, known to scholars of modernism through its glorification in the form of sculptor Jacob Epstein’s 1914 readymade Rock-Drill. These acts and others were performed at the Block Museum and at 6018|North for the 2017 Chicago Architecture Biennial with interdisciplinary collaborators Judd Morrissey and Abraham Avnisan, who wrote code for iPads enabling text frames to be advanced via the spinning and laborious clockwise lurching motions of the trip-up choristers, and to be punctuated throughout Act V by the flashing of archival 1913 strike posters in English, Finnish, Serbo-Croatian, and Italian. The librettist suggests navigating the text page by page instead of continuously scrolling to enhance the cinematic experience.

description: Isovaleryl-CoA dehydrogenase (IVD, EC 1.3.99.10) catalyzes the third step in the catabolism of leucine in mammals. Deficiency of this enzyme leads to the clinical disorder isovaleric acidemia. IVD has been purified and characterized from human and rat liver, and the x-ray crystallographic structure of purified recombinant human IVD has been reported. Nothing is known about IVD activity in plants, although cDNA clones from Arabidopsis thaliana and partial sequences from Gossypium hirsutum and Oryza sativa have been identified as putative IVDs based on sequence homology and immuno cross-reactivity. In this report we describe the identification and characterization of an IVD from pea, purification of the enzyme using a novel and rapid auxin affinity chromatography matrix, and cloning of the corresponding gene. At the amino acid level, pea IVD is 60% similar to human and rat IVD. The specific activity and abundance of plant IVD was found to be significantly lower than for its human counterpart and exhibits developmental regulation. Substrate specificity of the plant enzyme is similar to the human IVD, and it cross-reacts to anti-human IVD antibodies. Molecular modeling of the pea enzyme based on the structure of human IVD indicates a high degree of structural similarity among these enzymes. Glu-244, shown to function as the catalytic base in human IVD along with most of the amino acids that make up the acyl CoA binding pocket, is conserved in pea IVD. The genomic structure of the plant IVD gene consists of 13 exons and 12 introns, spanning approximately 4 kilobases, and the predicted RNA splicing sites exhibit the extended consensus sequence described for other plant genes.

description: Целью исследования было определение связи полиморфизма генов с традиционными факторами риска и сердечно-сосудистыми осложнениями. Исследование методом случай-контроль проводилось в период 2007-2011 гг.; в нем участвовали 405 пациентов с ишемической болезнью сердца (ИБС) и эпизодами острой ишемии миокарда, поступившими в Муниципальную клинику «Sfânta Treime», г. Кишинева. С помощью полимеразной цепной реакции и метода полиморфизма длин рестрикционных фрагментов определялись инсерционно-делеционный генотип ангиотензин-превращающего фермента (АПФ), полиморфизм A1166C гена рецептора к ангиотензину-II 1-го типа (АТ1), Asp298Glu (A/G) генотипы eNOS и PlA1/2 (A1/A2), генотипы полиморфизмов рецепторов GPIIb/IIIa. Авторы установили, что носительство D/D генотипа и D-аллеля в гене АПФ имеет положительную корреляцию с полиморфизмом высокого риска C/C гена АТ1 и ассоциировано с артериальной гипертензией (АГ) и сердечно-сосудистой смертностью. A2 /A2-генотип гена GP IIb/IIIa-рецепторов был ассоциирован с предрасположенностью к ИБС, высокой частотой инфаркта миокарда и дислипидемией, особенно у курильщиков. Доказано, что влияние маркеров полиморфизма eNOS на течение ИБС зависит от наличия АГ.
description: The aim of this study was to evaluate the gene polymorphisms association with conventional risk factors and cardiovascular complications. The case control study was conducted in 2007-2011 and included 405 patients with coronary artery disease (CAD) and acute ischemic episodes admitted to the Municipal Clinical Hospital “Sfânta Treime”, Chisinău. Insertion/deletion (I/D) genotypes of angiotensin-converting enzyme (ACE) and A1166C polymorphism of angiotensin II type 1 receptor gene, Asp298Glu (A/G) genotypes of the endothelial nitric oxide synthase (eNOS) and PlA1/2 (A1/A2) genotypes of A2/A2 genotype glycoprotein (GP) IIb/IIIa receptor gene (GPIIb/IIIa) receptor polymorphisms were identified by amplified polymerase chain reaction and restricted fragment length polymorphism. The authors concluded that the carrier of D/D genotype and D allele in ACE gene, being positively correlated with the risk C/C polymorphic variant of angiotensin II type 1 receptor gene, was associated with hypertension and cardiovascular death. A2/A2 genotype of GP IIb/IIIa receptor gene was associated with susceptibility to CAD and high frequency of myocardial infarction and dyslipidemia, particularly in smokers. The impact of eNOS polymorphic markers for CAD proved to be hypertension-mediated.

description: We propose a model of the evolution of the networks of scientific citations. The model takes an out-degree distribution (distribution of number of citations) and two parameters as input. The parameters capture the two main ingredients of the model, the aging of the relevance of papers and the formation of triangles when new papers cite old. We compare our model with three network structural quantities of an empirical citation network. We find that an unique point in parameter space optimizing the match between the real and model data for all quantities. The optimal parameter values suggest that the impact of scientific papers, at least in the empirical data set we model is proportional to the inverse of the number of papers since they were published.

description: Повышенная частота сердечных сокращений (ЧСС) в покое является независимым фактором риска развития сердечно-сосудистых заболеваний и увеличивает риск неблагоприятных прогнозов у пациентов с диагности рованным заболеванием сердечно-сосудистой системы. Повышенная ЧСС в течение длительного времени оказывает выраженный негативный эффект на здоровье. Опубликовано много статей о влиянии курения на ЧСС, в основном за счет положительного хронотропного эффекта никотина, являющегося основным компо нентом табачного дыма. В этой работе дана оценка достоверности гипотезы, что хроническое воздействие никотина на организм человека приводит к хроническому повышению ЧСС.
description: Elevated resting heart rate is an independent risk factor for developing cardiovascular disease and increases the risk of adverse outcomes in patients with established cardiovascular disease. Heart rate elevated over time is particularly deleterious to health. Tobacco use has been widely reported to affect heart rate, due principally to the acute positive chronotropic effect of its key component, nicotine. This review explores the proposition that chronic nicotine consumption equates to chronic elevated heart rate.

description: Il testo analizza i mitemi, le unità narrative essenziali dei miti, attraverso una lente strutturalista e critica, superando l’approccio convenzionale per esplorarne le origini più remote e le loro potenziali manipolazioni culturali. Dopo aver introdotto il concetto di mitema, descritto da Claude Lévi-Strauss come la più piccola unità di significato mitologico, l’indagine si sposta su un livello speculativo e archeologico, interrogandosi sull’origine ancestrale di questi frammenti narrativi. 

Vengono esaminati esempi di mitemi arcaici come il cacciatore e la preda, la Grande Madre, la caduta dal cielo e il serpente, ipotizzando che tali elementi rappresentino tracce di osservazioni cosmiche e fenomeni naturali rielaborati culturalmente nel corso del tempo.

In conclusione, il testo propone che i mitemi siano convenzioni simboliche condizionanti e impronte collettive, in costante metamorfosi, profondamente radicate nella pre-percezione umana e nella memoria cosmica.
Contiguous redshift parameterizations of the growth index

description: The growth rate of matter perturbations can be used to distinguish between different gravity theories and to distinguish between dark energy and modified gravity at cosmological scales as an explanation to the observed cosmic acceleration. We suggest here parameterizations of the growth index as functions of the redshift. The first one is given by $γ(a)=\tildeγ(a) \frac{1}{1+(a_{_{ttc}}/a)}+γ_{_{early}} \frac{1}{1+(a/a_{_{ttc}})}$ that interpolates between a low/intermediate redshift parameterization $\tildeγ(a)=γ_{_{late}}(a)= γ_0 + (1-a) γ_a$ and a high redshift $γ_{_{early}}$ constant value. For example, our interpolated form $γ(a)$ can be used when including the CMB to the rest of the data while the form $γ_{_{late}}(a)$ can be used otherwise. It is found that the parameterizations proposed achieve a fit that is better than 0.004% for the growth rate in a $Λ$CDM model, better than 0.014% for Quintessence-Cold-Dark-Matter (QCDM) models, and better than 0.04% for the flat Dvali-Gabadadze-Porrati (DGP) model (with $Ω_m^0=0.27$) for the entire redshift range up to $z_{_{CMB}}$. We find that the growth index parameters $(γ_0,γ_a)$ take distinctive values for dark energy models and modified gravity models, e.g. $(0.5655,-0.02718)$ for the $Λ$CDM model and $(0.6418,0.06261)$ for the flat DGP model. This provides a means for future observational data to distinguish between the models.

description: The mass reduction of components is one of the most effective ways to reduce fuel consumption and emissions in the automotive and aircraft industry. A lightweight strategy used for highly loaded components is the combination of different materials to workpiece compounds. In that way components can be designed depending on the local load using the most qualified material. For the production of high-performance workpiece compounds high quality requirements concerning the accuracy of dimension and shape as well as surface roughness must be fulfilled. However, machining of workpiece compounds leads to unfavorable changes of the workpiece quality in comparison to machining of the single materials. Significant shape deviations occur when different materials are machined alternately in one cutting operation. This is due to unequal material properties, cutting characteristics, chip formation mechanisms as well as characteristic interactions between the single components. This paper describes the causes of the three main criteria material height deviation, transition deviation and surface roughness deviation that significantly influence the surface quality in parallel machining. The focus is on the process understanding as well as modeling of the surface defects. The approaches and results show that the characteristic shape deviations can be predicted. With the knowledge of the causes that lead to the surface defects in parallel machining it is possible to optimize the process setup for a surface quality oriented machining process of a workpiece compound.

Comparative feeding habits of the fur seal (Callorhinus ursinus), sea lion (Eumetopias jubata) and harbour seal (Phoca vitulina) on the British Columbia coast.

description: Feeding habits of fur seals (Callhorinus ursinus), sea lions (Eumetopias jubata) and harbour seals (Phoca vitulina) have been examined along the British Columbia coast. Collections were made out to 35 miles from shore. All pertinent published and unpublished data have been combined with the object of assessing the effect of pinniped predation upon commercially valuable fish stocks. A total of 126 harbour seal stomachs, 2,113 fur seal stomachs and 393 sea lion stomachs were available. Comparative anatomy of the digestive tract was examined and notable differences were found in the relatively longer digestive tract and late eruption of permanent teeth in the sea lion. Published data indicate that fur seals, sea lions, and harbour seals eat an amount of food equal to 6%of their body weight per day with a range of 2% to 11%. All samples were grouped as to season and area of collection and comparative seasonal feeding habits were discussed. The effect of the reproductive period upon feeding habits was examined: there is little evidence regarding fur seal feeding habits on the rookeries except for conflicting observations made on harem bulls; the majority of the sea lion rookery population fasts for a few days only, during pupping; harbour seals on the Skeena River appear to fast for at least part of June. There is no evidence of interspecific competition between the three species studied on the British Columbia coast. Sea lions and harbour seals each year eat an estimated amount equivalent to 1.6% of the annual commercial salmon catch and 2.7% of the annual commercial herring catch. Predation at this level is believed to be of negligible importance in the reduction of existing salmon and herring stocks. Insufficient data from waters greater than 35 miles from shore precludes an assessment of fur seal predation upon ocean salmon. Further offshore collections should be made.

description: A dictionary is a set of finite words over some finite alphabet X. The omega-power of a dictionary V is the set of infinite words obtained by infinite concatenation of words in V. Lecomte studied in [Omega-powers and descriptive set theory, JSL 2005] the complexity of the set of dictionaries whose associated omega-powers have a given complexity. In particular, he considered the sets $W({\bf\Si}^0_{k})$ (respectively, $W({\bfΠ}^0_{k})$, $W({\bfΔ}_1^1)$) of dictionaries $V \subseteq 2^\star$ whose omega-powers are ${\bf\Si}^0_{k}$-sets (respectively, ${\bfΠ}^0_{k}$-sets, Borel sets). In this paper we first establish a new relation between the sets $W({\bfΣ}^0_{2})$ and $W({\bfΔ}_1^1)$, showing that the set $W({\bfΔ}_1^1)$ is "more complex" than the set $W({\bfΣ}^0_{2})$. As an application we improve the lower bound on the complexity of $W({\bfΔ}_1^1)$ given by Lecomte. Then we prove that, for every integer $k\geq 2$, (respectively, $k\geq 3$) the set of dictionaries $W({\bfΠ}^0_{k+1})$ (respectively, $W({\bf\Si}^0_{k+1})$) is "more complex" than the set of dictionaries $W({\bfΠ}^0_{k})$ (respectively, $W({\bf\Si}^0_{k})$) .

Mini-Workshop: Mathematical Models, Analysis, and Numerical Methods for Dynamic Fracture

description: The mathematical foundation of fracture mechanics has seen considerable advances in the last fifteen years. While this progress has been substantial, it has been largely limited to quasi-static evolutions based on global energy minimization, which is known to produce non-physical results. What is missing is a generally accepted mathematical theory of dynamic crack growth, which accounts for material inertia. Such a theory would not only be able to describe the most physically realistic setting, but it would also provide a trusted starting point to resolve pressing questions about quasistatic evolutions, e.g., a rigorous justification of the quasi-static setting as an asymptotic limit of inertial dynamics. This workshop brought together researchers in mathematical analysis, mechanics, applied mathematics, and numerical analysis and laid the groundwork for progress on these questions.

description: We present a quantitative morphological analysis using HST NICMOS H160- and ACS I775- band imaging of 25 spectroscopically confirmed submillimetre galaxies (SMGs) which have redshifts between z=0.7-3.4. Our analysis also employs a comparison sample of more typical star-forming galaxies at similar redshifts (such as LBGs) which have lower far-infrared luminosities. This is the first large-scale study of the morphologies of SMGs in the near-infrared at ~0.1" resolution (<1kpc). We find that the half light radii of the SMGs (r_h=2.3+/-0.3 and 2.8+/-0.4kpc in the observed I- and H-bands respectively) and asymmetries are not statistically distinct from the comparison sample of star-forming galaxies. However, we demonstrate that the SMG morphologies differ more between the rest-frame UV and optical-bands than typical star-forming galaxies and interpret this as evidence for structured dust obscuration. We show that the composite observed H-band light profile of SMGs is better fit with a Sersic index with n~2, suggesting the stellar structure of SMGs is best described by a spheroid/elliptical galaxy light distribution. We also compare the sizes and stellar masses of SMGs to local and high-redshift populations, and find that the SMGs have stellar densities which are comparable to local early-type galaxies, as well as luminous, red and dense galaxies at z~1.5 which have been proposed as direct SMG descendants, although the SMG stellar masses and sizes are systematically larger. Overall, our results suggest that the physical processes occuring within the galaxies are too complex to be simply characterised by the rest-frame UV/optical morphologies which appear to be essentially decoupled from all other observables, such as bolometric luminosity, stellar or dynamical mass.

description: Tat systems transport folded proteins across energized membranes of bacteria, archaea, and plant plastids. In Escherichia coli, TatBC complexes recognize the transported proteins, and TatA complexes are recruited to facilitate transport. We achieved an abstraction of TatA from membranes without use of detergents and observed a co-purification of PspA, a mem-brane- stress response protein. The N-terminal transmembrane domain of TatA was required for the interaction. Electron microscopy displayed TatA complexes in direct contact with PspA. PspB and PspC were important for the TatA-PspA contact. The activator protein PspF was not involved in the PspATatA interaction, demonstrating that basal levels of PspA already interact with TatA. Elevated TatA levels caused membrane stress that induced a strictly PspBC- and PspF-dependent up-regulation of PspA. TatA complexes were found to destabilize membranes under these conditions. At native TatA levels, PspA deficiency clearly affected anaerobic TMAO respiratory growth, suggesting that energetic costs for transport of large Tat substrates such as TMAO reductase can become growth limiting in the absence of PspA. The physiological role of PspA recruitment to TatA may therefore be the control of membrane stress at active translocons. © 2012 by The American Society for Biochemistry and Molecular Biology, Inc.

description: That there exist two losing games that can be combined, either by random mixture or by nonrandom alternation, to form a winning game is known as Parrondo's paradox. We establish a strong law of large numbers and a central limit theorem for the Parrondo player's sequence of profits, both in a one-parameter family of capital-dependent games and in a two-parameter family of history-dependent games, with the potentially winning game being either a random mixture or a nonrandom pattern of the two losing games. We derive formulas for the mean and variance parameters of the central limit theorem in nearly all such scenarios; formulas for the mean permit an analysis of when the Parrondo effect is present.

PREDICTIONS FOR gg ?? pp: WHAT PHOTONS AT DAFNE WILL SEE
Creators: name: M. R. PENNINGTON
Publisher: name: INFN Open Access Repository
Year: 1992

description: The aim of this article is threefold. Firstly, to discuss briefly why two photon interactions are interesting and then to review what is presently known about them experimentally. Thirdly, to consider how we may predict what DAPHNE may measure. The channel of particular concern is γγ->π^0π^0. The cross-section for this process can be readly calculated in chiral perturbation theory, but the lowest order prediction is not in good agreement with existing data. However, general principles relate this process in other reactions with \π\π final states that allow a more general calculational scheme. This predicts cross-sections in much better accord with experiment. The reasons why are analyzed in detail. Moreover, we are then able to show how precision measurements of the γγ->ππ cross-section, both for π^+π^- and π^0π^0, would in turn constrain our knoledge of ππ phases.
Mini-Workshop: Random Trees, Information and Algorithms
Creators: name: (:Unkn) Unknown
Publisher: name: Zürich : EMS Publ. House
Year: 2011
Subjects: subject: Konferenzschrift
subject: 510

description: The subject of this Mini-Workshop is the probabilistic analysis of random tree models that originate from applications in Computer Science. Emphasis is put on their connections to algorithms and information theory. Trees with a stochastic growth dynamic appear in Computer Science as data structures, in the context of coding schemes as well as connected to fundamental algorithms such as sorting, searching and selecting. The focus of this Mini-Workshop is on probabilistic and analytic techniques that have been developed recently in the asymptotic analysis of random trees such as martingale methods, connections to branching random walks, the contraction method, the method of moments as well as various techniques based on generating functions.

description: C4 photosynthesis evolvedmore than 60 times independently in different plant lineages. Each time,multiple genes were recruited into C4 metabolism. The corresponding promoters acquired new regulatory features such as high expression, light induction, or cell typespecific expression in mesophyll or bundle sheath cells. We have previously shown that histone modifications contribute to the regulation of the model C4 phosphoenolpyruvate carboxylase (C4-Pepc) promoter in maize (Zea mays). We here tested the light- and cell type-specific responses of three selected histone acetylations and two histone methylations on five additional C4 genes (C4-Ca, C4- Ppdk, C4-Me, C4-Pepck, and C4-RbcS2) in maize. Histone acetylation and nucleosome occupancy assays indicated extended promoter regions with regulatory upstream regions more than 1,000 bp from the transcription initiation site for most of these genes. Despite any detectable homology of the promoters on the primary sequence level, histone modification patterns were highly coregulated. Specifically, H3K9ac was regulated by illumination, whereas H3K4me3 was regulated in a cell type-specific manner. We further compared histone modifications on the C4-Pepc and C4-Me genes from maize and the homologous genes from sorghum (Sorghum bicolor) and Setaria italica.Whereas sorghum and maize share a common C4 origin, C4 metabolism evolved independently in S. italica. The distribution of histone modifications over the promoters differed between the species, but differential regulation of light-induced histone acetylation and cell type-specific histone methylation were evident in all three species. We propose that a preexisting histone code was recruited into C4 promoter control during the evolution of C4 metabolism. © 2013 American Society of Plant Biologists. All Rights Reserved.

description: Using viscous relativistic hydrodynamics we show that systematic studies of the impact parameter dependence of the eccentricity scaled elliptic flow can distinguish between different models for the calculation of the initial source eccentricity. This removes the largest present uncertainty in the extraction of the specific viscosity of the matter created in relativistic heavy-ion collisions from precise elliptic flow measurements.
