description: Our primary aim is to develop a theory of equivariant genera for stably complex manifolds equipped with compatible actions of a torus T^k. In the case of omnioriented quasitoric manifolds, we present computations that depend only on their defining combinatorial data; these draw inspiration from analogous calculations in toric geometry, which seek to express arithmetic, elliptic, and associated genera of toric varieties in terms only of their fans. Our theory focuses on the universal toric genus Φ, which was introduced independently by Krichever and Loeffler in 1974, albeit from radically different viewpoints. In fact Φis a version of tom Dieck's bundling transformation of 1970, defined on T^k-equivariant complex cobordism classes and taking values in the complex cobordism algebra of the classifying space. We proceed by combining the analytic, the formal group theoretic, and the homotopical approaches to genera, and refer to the index theoretic approach as a recurring source of insight and motivation. The resultant flexibility allows us to identify several distinct genera within our framework, and to introduce parametrised versions that apply to bundles equipped with a stably complex structure on the tangents along their fibres. In the presence of isolated fixed points, we obtain universal localisation formulae, whose applications include the identification of Krichever's generalised elliptic genus as universal amongst genera that are rigid on SU-manifolds. We follow the traditions of toric geometry by working with a variety of illustrative examples wherever possible. For background and prerequisites we attempt to reconcile the literature of east and west, which developed independently for several decades after the 1960s.

description: One field of particular interest in Number Theory concerns the gaps between consecutive primes. Within the last few years, very important results have been achieved on how small these gaps can be. The strongest of these results were obtained by Dan Goldston, Janos Pintz and Cem Yalcin Yildirim. The present work begins by generalizing their results so that they can be applied to related problems in a more direct manner. Additionally, we improve the bound for $F_2$ (concerning the maximal gap in a block of three primes) obtained by the authors' first paper with our generalization.

Subjects: tax planning; income taxation; personal finance

description: The current paper covers one of the tax optimization schemes popular in Estonia – full or partial replacement of labor income with dividends. Such scheme is used by some owner-managers as the regulation concerning emoluments of members of management body is very flexible. The main incentive to use the scheme is to reduce tax burden as dividends are only subject to income tax but emoluments to the members of management body are also taxed with the social tax. Basic results show that considered schemes are widespread. We estimate that due to replacement of salaries and wages with dividends there was a significant loss in social tax revenues in Estonia during 2005-2008. In majority of the sectors average dividends of ownermanagers in 2008 were higher than their average salaries. Also, the average amount of owner-managers’ emoluments in majority of the sectors was below the national monthly average salary, in some cases it was even below subsistence level

Saprophytes in the stem of living, healthy Tsuga heterophylla (Raf.) Sarg. and their role in decay resistance of the wood
Creators: name: Hudak, Janos
Publisher: name: University of British Columbia
Year: 2011

description: It was demonstrated that the sound wood of two stems of living western hemlock, Tsuga heterophylla (Raf.) Sarg., was colonized by microorganisms, which were isolated by shaking samples of the wood in sterile distilled water. The microfloras inhibited the growth of Fomes annosus, (Fr.) Cke., and Poria monticola Murr. when added to one per cent malt agar. The test fungi were also inhibited on untreated surface sterilized wood incubated at one hundred per cent relative humidity at room temperature. Significant variation was observed, in the rate of inhibition between the sapwood and heartwood and between the various sections of the two stems investigated. A drier environment (higher agar concentration of malt agar media, and lower relative humidity with wood) resulted in a significant decrease in inhibition rate of F. annosus and P. monticola. Autoclaving the experimental material led to the loss of inhibition with both malt agar media and wood. Removal of the microorganisms from the shake solutions by Millipore filtration also resulted in loss of the inhibiting factor. The relatively drier environment did not effect the rate of growth of the test fungi on autoclaved wood and in malt agar containing the autoclaved portion of the shake solutions. Results of the experiment provide evidence that the microfloras inhabiting the sound wood were responsible for inhibition of F. annosus and. P. monticola. Furthermore, sufficient moisture level appeared necessary for maintaining the inhibiting power of these microorganisms.
Error Rates of the Maximum-Likelihood Detector for Arbitrary Constellations: Convex/Concave Behavior and Applications

description: Motivated by a recent surge of interest in convex optimization techniques, convexity/concavity properties of error rates of the maximum likelihood detector operating in the AWGN channel are studied and extended to frequency-flat slow-fading channels. Generic conditions are identified under which the symbol error rate (SER) is convex/concave for arbitrary multi-dimensional constellations. In particular, the SER is convex in SNR for any one- and two-dimensional constellation, and also in higher dimensions at high SNR. Pairwise error probability and bit error rate are shown to be convex at high SNR, for arbitrary constellations and bit mapping. Universal bounds for the SER 1st and 2nd derivatives are obtained, which hold for arbitrary constellations and are tight for some of them. Applications of the results are discussed, which include optimum power allocation in spatial multiplexing systems, optimum power/time sharing to decrease or increase (jamming problem) error rate, an implication for fading channels ("fading is never good in low dimensions") and optimization of a unitary-precoded OFDM system. For example, the error rate bounds of a unitary-precoded OFDM system with QPSK modulation, which reveal the best and worst precoding, are extended to arbitrary constellations, which may also include coding. The reported results also apply to the interference channel under Gaussian approximation, to the bit error rate when it can be expressed or approximated as a non-negative linear combination of individual symbol error rates, and to coded systems.

description: Macroscopic concentration of massless charge carriers with linear conic spectrum - Dirac Fermions (DF) - was shown in 2004 to exist in highly oriented pyrolytic graphite (HOPG) and governs its electronic properties. These carriers can have the same nature as DF observed in graphite monolayer(graphene) and let to view HOPG as superposition of 2D carbon layers, almost independent electronically. We overview here the recent experimental evidences of 2D DF in graphite and their similarity with carriers in graphene.

The Christian Moral Life: Directions for the Journey to Happiness
Creators: name: Rziha, John
Publisher: name: University of Notre Dame
Year: 2023

description: To take a journey, travelers must know where they are, where they are going, and how to get there. Moral theology examines the same three truths. _The Christian Moral Life_ is a handbook for moral theology that uses the theme of a journey to explain its key ethical concepts. First, humans begin with their creation in the image of God. Secondly, the goal of the journey is explained as a loving union with God, to achieve a share in his eternal happiness. Third and finally, the majority of the book examines how to attain this goal. Within the journey motif, the book covers the moral principles essential for attaining true happiness. Based on an examination of the moral methodology in the bible, the book discusses the importance of participating in divine nature through grace in order to attain eternal happiness. It further notes the role of law, virtue, and the gifts of the Holy Spirit in guiding and transforming humans into friends of God, who participate in his happiness. Following this section on moral theology in general, the book analyzes the individual virtues to give more concrete guidance. The entire project builds upon the insights of great Christian thinkers, such as Thomas Aquinas, Th\u00e9r\u00e8se of Lisieux, and John Paul II, to uncover the moral wisdom in scripture and to show people how to be truly happy both in this life and the next. This book will be of great interest to undergraduate students of moral theology, priests and seminarians, parents and teachers seeking to raise and to form happy children, and anyone interested in discovering the meaning of true happiness.

description: We present a Nobeyama 45 m Radio Telescope map and Australia Telescope Compact Array pointed observations of N2H+ 1-0 emission towards the clustered, low mass star forming Oph B Core within the Ophiuchus molecular cloud. We compare these data with previously published results of high resolution NH3 (1,1) and (2,2) observations in Oph B. We use 3D Clumpfind to identify emission features in the single-dish N2H+ map, and find that the N2H+ `clumps' match well similar features previously identified in NH3 (1,1) emission, but are frequently offset to clumps identified at similar resolution in 850 micron continuum emission. Wide line widths in the Oph B2 sub-Core indicate non-thermal motions dominate the Core kinematics, and remain transonic at densities n ~ 3 x 10^5 cm^-3 with large scatter and no trend with N(H2). Non-thermal motions in Oph B1 and B3 are subsonic with little variation, but also show no trend with H2 column density. Over all Oph B, non-thermal N2H+ line widths are substantially narrower than those traced by NH3, making it unlikely NH3 and N2H+ trace the same material, but the v_LSR of both species agree well. We find evidence for accretion in Oph B1 from the surrounding ambient gas. The NH3/N2H+ abundance ratio is larger towards starless Oph B1 than towards protostellar Oph B2, similar to recent observational results in other star-forming regions. Small-scale structure is found in the ATCA N2H+ 1-0 emission, where emission peaks are again offset from continuum emission. In particular, the ~1 M_Sun B2-MM8 clump is associated with a N2H+ emission minimum and surrounded by a broken ring-like N2H+ emission structure, suggestive of N2H+ depletion. We find a strong general trend of decreasing N2H+ abundance with increasing N(H2) in Oph B which matches that found for NH3.

description: The role of external forces in systems exhibiting anomalous diffusion is discussed on the basis of the describing Langevin equations. Since there exist different possibilities to include the effect of an external field the concept of {\it biasing} and {\it decoupled} external fields is introduced. Complementary to the recently established Langevin equations for anomalous diffusion in a time-dependent external force-field [{\it Magdziarz et al., Phys. Rev. Lett. {\bf 101}, 210601 (2008)}] the Langevin formulation of anomalous diffusion in a decoupled time-dependent force-field is derived.

description: The purpose of the article is to show the need and opportunities for the public organisation of bus transport in Estonia. In order to achieve this goal, it is necessary to investigate Estonian and international experience in the organisation of passenger transport, its theoretical background and the resulting special measures. If we look at a specific transport service, the exclusion of the consumption thereof for a non-payer is no problem either in principle or technically. Here, public goods and market failure are not as much related to a specific transport service, but to the general availability thereof to the majority of the population. This is exactly the circumstance that the market may not necessarily guarantee. Here, the economic policy theory offers two solutions, which application in Estonian case are analysed in this article: 1) the cross-subsidisation of some lines at the expense of others, which, of course, presumes the prevention of the so-called price skimming with the establishment of regional monopolies and granting of special rights for them; 2) if cross-subsidisation cannot ensure a wide enough access to passenger transport, subsidisation must be added

Year: 2011

description: Lignin contents of extractive-free wood meals prepared from three adjacent rings of mature wood, sampled at breast height, of amabilis fir, Douglas fir, western red cedar, Sitka spruce, and western hemlock were determined according to the micro-method of Johnson, Moore and Zank. Each of three rings within each species was divided into six positions from earlywood to latewood. Wood meals of 40-80 mesh size were extracted successively with ethyl ether, absolute ethyl alcohol and hot-water, and then solubilized with acetyl bromide and absorbence was calibrated against Klason lignin values. Wood methoxyl content of these same samples had been studied previously. Lignin contents were found to be highly significantly different within positions of growth increments for amabilis fir, Douglas fir, western red cedar and Sitka spruce, but no significant difference was found for western hemlock. Highly significant difference was found between growth rings for western red cedar and similarly significant difference was found for Douglas fir. No significant differences were obtained between growth rings for the other three species, although a slight but definite increase in lignin content with age was observed. Highly significant differences were also found between species and for total averages of each position for the five species. Earlywoods were higher in lignin content than latewood in each species by: Douglas fir, 2.27%; amabilis fir, 2.06%; western red cedar, 1.28%; Sitka spruce, 1.08%; and western hemlock, 0.46%. Lignin contents for individual species were in the order of: western hemlock, 32.85% (32.36-34.04%); western red cedar, 31.23% (29.69-32.68%); amabilis fir, 27.51% (26.17-28.24%); Douglas fir, 26.48% (24.08-28.66%); and Sitka spruce, 25.81% (24.91-26.98%). The correlation coefficient testing association between lignin and wood methoxyl was highly significant for amabilis fir (0.971), Douglas fir (O.913) and western red cedar (0.684). Non-significant correlation occurred with Sitka spruce (0.467) and western hemlock (0.340). The relationship between lignin and wood methoxyl appeared independent of species. The non-lignin methoxyl contents for the five species were estimated and the results showed that these were also independent of species.

description: This thesis is an ethnographic work about young Japanese adults in their 20s and 30s and the Obon festival. It is based mainly on fieldwork conducted in Tokyo and Osaka during July and August 2019. The primary goal of this research is to explore how young Japanese adults view and participate in the Obon festival. Through this a better understanding of the interconnectedness of family and ancestor worship is possible. This exploration is achieved primarily through the use of participant observation and semi-structured interviews. Eleven interviews were conducted during the two-month period. How young adults view the festival varies greatly. Some view it as a very important time of the year while others do not care about it at all. Many factors such as work and school impact how young adults participate in the festival. The most influential of these factors in shaping how an individual views and participates in the festival is family.

Subjects: taylor rule; interest rate policy

description: In modern monetary policy nearly every central bank has an output driven task to fulfil. This could be price stability or the attainment of a stable inflation rate. In order to establish whether the monetary policy has reached its goals, it is possible to use monetary rules ex post as a benchmark. For this we will use the Taylor rule and interest rate to describe the European interest rate policy from 1999 to 2009. The main result is that from 2000 till 2008 the Taylor interest rate is much higher than its benchmarks EONIA and EURIBOR. Only for the year 1999 a neutral interest rate emerges. Furthermore the paper shows that the European interest rate policy missed its Taylor interest rate benchmark every time except 1999. So it is possible to state that the European interest rate policy was too expansive.

description: Because accretion and merger shocks in clusters of galaxies may accelerate particles to high energies, clusters are candidate sites for the origin of ultra-high-energy (UHE) cosmic-rays. A prediction was presented for gamma-ray emission from a cluster of galaxies at a detectable level with the current generation of imaging atmospheric Cherenkov telescopes. The gamma-ray emission was produced via inverse Compton upscattering of cosmic microwave background (CMB) photons by electron-positron pairs generated by collisions of UHE cosmic rays in the cluster. We observed two clusters of galaxies, Abell 3667 and Abell 4038, searching for very-high-energy gamma-ray emission with the CANGAROO-III atmospheric Cherenkov telescope system in 2006. The analysis showed no significant excess around these clusters, yielding upper limits on the gamma-ray emission. From a comparison of the upper limit for the north-west radio relic region of Abell 3667 with a model prediction, we derive a lower limit for the magnetic field of the region of ~0.1 micro G. This shows the potential of gamma-ray observations in studies of the cluster environment. We also discuss the flux upper limit from cluster center regions using a model of gamma-ray emission from neutral pions produced in hadronic collisions of cosmic-ray protons with the intra-cluster medium (ICM). The derived upper limit of the cosmic-ray energy density within this framework is an order of magnitude higher than that of our Galaxy.

description: The paper examines determinants of investment decisions of Estonian companies. Within investment decision determinants the influence of interest rates and cost of capital get special attention as well as the analysis of liquidity constraints. The study is based on answers of questionnaires received from 44 companies of Estonia. Results of the study show that most important determinants of investments are related to risk and uncertainty followed by liquidity constraints and business confidence determinants. Interest rate determinant and cost of capital consideration has small influence to investment decisions as well as have a low profile in overall management focus. Liquidity constraints on other hand should be considered an important decision factor behind investment decisions

description: The role of national universities and other higher education institutions in knowledge transfer in countries with post-Soviet economies has been studied in very modest extent, especially in the context of small countries. This paper concentrates on the organizational culture aspects playing important role in the commercialization of university research within the university knowledge transfer and knowledge based society framework in Estonia. Knowledge sharing and commercialization depend on nature of organizational culture, as a part of internal environment. Two largest Estonian universities (University of Tartu and Tallinn University of Technology) are compared in various factors influencing knowledge transfer using document analysis and interviews. The present study has shown that knowledge transfer faces numerous issues, and in particular soft issues (individual mindsets and organizational values) may differ from university to university

description: Background:Fibroblast growth factor 9 (FGF9) is reported to be associated with the pathogenesis of cancers. However, its clinic significance in prostate cancer (PCa) had not yet to be elucidated. The aim of this study was to investigate the diagnostic value of FGF9 in PCa. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) and western blot analyses were used to detect the expression of serum FGF9 at mRNA and protein level in 90 PCa patients, 48 prostatic benign diseases (PBD) patients and 30 normal individuals. The association between FGF9 and clinicopathological features was determined by Chi-square test. Receiver-operator characteristic (ROC) was established to evaluate the diagnostic performance of FGF9 and PSA. Results: Serum FGF9 expression was significantly elevated in PCa patients (p p FGF9 expression was also associated with lymph node metastasis (p = .010). The diagnostic value of FGF9 was higher than the conventional tumor marker PSA with a AUC of 0.846 combined with a sensitivity of 83.3% and a specificity of 81.1%. Conclusions: Serum FGF9 may be employed as a potential diagnostic biomarker of PCa.

description: In this study, an attempt has been made to evaluate the effect of products of β-galactosidase (βGS) catalyzed reaction i.e. glucose and galactose and their structurally related compound vitamin C (VC) on the catalytic activity of native and PANI-CS-NC and PANI-CS-Ag-NC adsorbed βGS. Results indicated a decline in catalytic activity of soluble enzyme in the presence of all investigated compounds. The order of inhibition was found to be VC w/v), while the native enzyme exhibited only 18% of its original activity. A significant decrease in absorbance and fluorescence intensity was evaluated in soluble enzyme incubated in the presence of all investigated compounds. Three-dimensional fluorescence graphs, CD and FT-IR spectroscopic studies illustrated noteworthy conformational changes in the secondary structure and microenvironment of the soluble enzyme in the presence of VC and tested sugars. These results suggest that both PANI-CS-NC and PANI-CS-Ag-NC bound βGS are more resistant to the exposure caused by the higher concentration of added glucose, galactose, and VC and, therefore, can be effectively utilized for the production of a hassle-free lactose nano-biosensor.

description: We present a description of the design and usage of a new synoptic pipeline and database model for time series photometry in the VISTA Data Flow System (VDFS). All UKIRT-WFCAM data and most of the VISTA main survey data will be processed and archived by the VDFS. Much of these data are multi-epoch, useful for finding moving and variable objects. Our new database design allows the users to easily find rare objects of these types amongst the huge volume of data being produced by modern survey telescopes. Its effectiveness is demonstrated through examples using Data Release 5 of the UKIDSS Deep Extragalactic Survey (DXS) and the WFCAM standard star data. The synoptic pipeline provides additional quality control and calibration to these data in the process of generating accurate light-curves. We find that 0.6+-0.1% of stars and 2.3+-0.6% of galaxies in the UKIDSS-DXS with K<15 mag are variable with amplitudes ΔK>0.015 mag

mutational analysis of SARS CoV-2 strains

description: Contact information for joining the Bellevue College Biology Club can be found below. Abstract Mutations in the genetic sequences of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) have been instrumental in shaping the ongoing pandemic. The emergence of distinct strains highlights the significance of these mutations. In order to understand implications and potential impact on virulence, we investigated prevalent SARS-CoV-2 strains from the GISAID database and used a custom python script to identify the location of mutations and their potential effects on protein amino acid sequences. Our comprehensive analysis revealed mutations accumulated throughout the pandemic, particularly in the spike protein gene (S gene), which exhibited high mutational diversity and reduced conservation. Notably, mutations such as N439K, T478K, and D614G were found to potentially impact viral infectivity, antibody resistance, and binding affinity to the ACE2 receptor. Additionally, the phylogenetic tree analysis indicated that the original strain, NC_045512.2, may not be the original strain, but rather a strain that researchers first discovered, suggesting the existence of predated strains. These findings enhance our understanding of SARS-CoV-2 virology and provide valuable insights into the factors influencing strain prevalence and their potential implications for transmission and disease severity.

description: We propose a new approach to the analysis of Loopy Belief Propagation (LBP) by establishing a formula that connects the Hessian of the Bethe free energy with the edge zeta function. The formula has a number of theoretical implications on LBP. It is applied to give a sufficient condition that the Hessian of the Bethe free energy is positive definite, which shows non-convexity for graphs with multiple cycles. The formula clarifies the relation between the local stability of a fixed point of LBP and local minima of the Bethe free energy. We also propose a new approach to the uniqueness of LBP fixed point, and show various conditions of uniqueness.

Extraction of the neutron electric form factor from measurements of inclusive double spin asymmetries
Creators: name: (:Unkn) Unknown
Publisher: name: My University
Year: 2017
Subjects: nucl-ex

description: © 2017 American Physical Society. Background: Measurements of the neutron charge form factor, GEn, are challenging because the neutron has no net charge. In addition, measurements of the neutron form factors must use nuclear targets which require accurately accounting for nuclear effects. Extracting GEn with different targets and techniques provides an important test of our handling of these effects. Purpose: The goal of the measurement was to use an inclusive asymmetry measurement technique to extract the neutron charge form factor at a four-momentum transfer of 1(GeV/c)2. This technique has very different systematic uncertainties than traditional exclusive measurements and thus serves as an independent check of whether nuclear effects have been taken into account correctly. Method: The inclusive quasielastic reaction 3He (e′) was measured at Jefferson Laboratory. The neutron electric form factor, GEn, was extracted at Q2=0.98(GeV/c)2 from ratios of electron-polarization asymmetries measured for two orthogonal target spin orientations. This Q2 is high enough that the sensitivity to GEn is not overwhelmed by the neutron magnetic contribution, and yet low enough that explicit neutron detection is not required to suppress pion production. Results: The neutron electric form factor, GEn, was determined to be 0.0414±0.0077(stat)±0.0022(syst), providing the first high-precision inclusive extraction of the neutron's charge form factor. Conclusions: The use of the inclusive quasielastic 3He (e′) with a four-momentum transfer near 1(GeV/c)2 has been used to provide a unique measurement of GEn. This new result provides a systematically independent validation of the exclusive extraction technique results and implies that the nuclear corrections are understood. This is contrary to the proton form factor where asymmetry and differential cross section measurements have been shown to have large systematic differences.

Understanding and Mapping Natural Beauty

Year: 2017
Subjects: cs.CV

description: © 2017 IEEE. While natural beauty is often considered a subjective property of images, in this paper, we take an objective approach and provide methods for quantifying and predicting the scenicness of an image. Using a dataset containing hundreds of thousands of outdoor images captured throughout Great Britain with crowdsourced ratings of natural beauty, we propose an approach to predict scenicness which explicitly accounts for the variance of human ratings. We demonstrate that quantitative measures of scenicness can benefit semantic image understanding, content-aware image processing, and a novel application of cross-view mapping, where the sparsity of ground-level images can be addressed by incorporating unlabeled overhead images in the training and prediction steps. For each application, our methods for scenicness prediction result in quantitative and qualitative improvements over baseline approaches.
Baptists in British Columbia : a struggle to maintain "sectarianism"
Creators: name: Richards, John Byron
Publisher: name: University of British Columbia
Year: 2011

description: It is generally agreed that Baptists represent one of the largest bodies of "sectarian" opinion. The term "sectarianism" is used in a sociological rather than a polemical or derogatory sense. It serves to indicate the basic attitude of a socially exclusive or "sect-type" religious organization as differentiated from a "church-type", or socially inclusive and accommodative, religious body. Until recently it has been an accepted procedure to explain religious diversity in purely theological terms. Since the turn of the century an effort has been made to examine the social and economic factors in religious development. The "frontier thesis" has been evoked to explain sectarianism, and sociologists have tended to place all their conclusions within the framework of environmental determinism. Such an approach appears to involve a denial of the intrinsic validity and spiritual relevance of theological ideas. It is the contention of this thesis that religious diversity among Baptists in British Columbia is to be explained both in terms of environmental influences and in terms of ideas which were "imported" from the Old World and the United States. In the Christian tradition such ideas came mediately from Western Europe, which in turn had "imported" them from Palestine. Immediately, these ideas came from the Scriptures, which were regarded by sectarians as authoritative. While the author holds to the intrinsic validity of Biblical theological concepts, no attempt is made here to substantiate this view, this task being left to the Christian apologist. Within the scope of this thesis it shall suffice to demonstrate that Baptists in British Columbia were strongly influenced by the "imported1' ideas of Biblical theology and by the "imported" concepts of religious liberalism. The frontier environment was not the originator of these ideas, but gave an opportunity for the free interplay of these ideas. The net result of this interplay in British Columbia has been Baptist groups which bear a resemblance to Old World counterparts, and which, at the same time, bear the stamp of American influence and Canadian national characteristics. British Columbia Baptists are what they are because of economic, social, theological and spiritual factors. None of these factors can be completely segregated and viewed in splendid isolation. Baptist sectarianism is related not only to society but also to the ideas of the New Testament. In the British Columbia context, "the struggle to maintain sectarianism" was a struggle to maintain the sectarian interpretation of New Testament principles, in spite of the challenge of other theological ideas, in the milieu of the social and economic influences of frontier and modern society.

description: © 2018 Nelson et al. Type I males of the Pacific midshipman fish (Porichthys notatus) vibrate their swimbladder to generate mating calls, or "hums," that attract females to their nests. In contrast to the intermittent calls produced by male Atlantic toadfish (Opsanus tau), which occur with a duty cycle (calling time divided by total time) of only 3-8%, midshipman can call continuously for up to an hour. With 100% duty cycles and frequencies of 50-100 Hz (15°C), the superfast muscle fibers that surround the midshipman swimbladder may contract and relax as many as 360,000 times in 1 h. The energy for this activity is supported by a large volume of densely packed mitochondria that are found in the peripheral and central regions of the fiber. The remaining fiber cross section contains contractile filaments and a well-developed network of sarcoplasmic reticulum (SR) and triadic junctions. Here, to understand quantitatively how Ca2+ is managed by midshipman fibers during calling, we measure (a) the Ca2+ pumpingversus- pCa and force-versus-pCa relations in skinned fiber bundles and (b) changes in myoplasmic free [Ca2+] (Δ[Ca2+]) during stimulated activity of individual fibers microinjected with the Ca2+ indicators Mag-fluo-4 and Fluo-4. As in toadfish, the force-pCa relation in midshipman is strongly right-shifted relative to the Ca2+ pumping- pCa relation, and contractile activity is controlled in a synchronous, not asynchronous, fashion during electrical stimulation. SR Ca2+ release per action potential is, however, approximately eightfold smaller in midshipman than in toadfish. Midshipman fibers have a larger time-averaged free [Ca2+] during activity than toadfish fibers, which permits faster Ca2+ pumping because the Ca2+ pumps work closer to their maximum rate. Even with midshipman's sustained release and pumping of Ca2+, however, the Ca2+ energy cost of calling (per kilogram wet weight) is less than twofold more in midshipman than in toadfish.
Scaling behavior of domain walls at the T=0 ferromagnet to spin-glass transition

description: We study domain-wall excitations in two-dimensional random-bond Ising spin systems on a square lattice with side length L, subject to two different continuous disorder distributions. In both cases an adjustable parameter allows to tune the disorder so as to yield a transition from a spin-glass ordered ground state to a ferromagnetic groundstate. We formulate an auxiliary graph-theoretical problem in which domain walls are given by undirected shortest paths with possibly negative distances. Due to the details of the mapping, standard shortest-path algorithms cannot be applied. To solve such shortest-path problems we have to apply minimum-weight perfect-matching algorithms. We first locate the critical values of the disorder parameters, where the ferromagnet to spin-glass transition occurs for the two types of the disorder. For certain values of the disorder parameters close to the respective critical point, we investigate the system size dependence of the width of the the average domain-wall energy (~L^θ) and the average domain-wall length (~L^df). Performing a finite-size scaling analysis for systems with a side length up to L=512, we find that both exponents remain constant in the spin-glass phase, i.e. θ~- 0.28 and df~1.275. This is consistent with conformal field theory, where it seems to be possible to relate the exponents from the analysis of Stochastic Loewner evolutions (SLEs) via df-1=3/[4(3+θ)]. Finally, we characterize the transition in terms of ferromagnetic clusters of spins that form, as one proceeds from spin-glass ordered to ferromagnetic ground states.
