Power amplification in an isolated muscle-tendon unit is load dependent

description: During rapid movements, tendons can act like springs, temporarily storing work done by muscles and then releasing it to power body movements. For some activities, such as frog jumping, energy is released from tendon much more rapidly than it is stored, thus amplifying muscle power output. The period during which energy is loaded into a tendon by muscle work may be aided by a catch mechanism that restricts motion, but theoretical studies indicate that power can be amplified in a muscle–tendon load system even in the absence of a catch. To explore the limits of power amplification with and without a catch, we studied the bullfrog plantaris muscle–tendon during in vitro contractions. A novel servomotor controller allowed us to measure muscle–tendon unit (MTU) mechanical behavior during contractions against a variety of simulated inertial-gravitational loads, ranging from zero to 1× the peak isometric force of the muscle. Power output of the MTU system was load dependent and power amplification occurred only at intermediate loads, reaching ∼1.3× the peak isotonic power output of the muscle. With a simulated anatomical catch mechanism in place, the highest power amplification occurred at the lowest loads, with a maximum amplification of more than 4× peak isotonic muscle power. At higher loads, the benefits of a catch for MTU performance diminished sharply, suggesting that power amplification >2.5× may come at the expense of net mechanical work delivered to the load.

description: Formation mechanisms of single, twin, and double hypernuclei from Xi^- absorption at rest on 12C are investigated with an refined microscopic transport model, that incorporates the recently developed Quantal Langevin treatment into Antisymmetrized Molecular Dynamics. The quantum fluctuations suppress the formation probability of double hyperfragments to around 10%, which is comparable to the experimental data, and the dynamical formation of twin hyperfragment can be described qualitatively.

description: We present experimental data on H2 formation processes on gas-phase polycyclic aromatic hydrocarbon (PAH) cations. This process was studied by exposing coronene radical cations, confined in a radio-frequency ion trap, to gas phase H atoms. Sequential attachment of up to 23 hydrogen atoms has been observed. Exposure to atomic D instead of H allows one to distinguish attachment from competing abstraction reactions, as the latter now leave a unique fingerprint in the measured mass spectra. Modeling of the experimental results using realistic cross sections and barriers for attachment and abstraction yield a 1:2 ratio of abstraction to attachment cross sections. The strong contribution of abstraction indicates that H2 formation on interstellar PAH cations is an order of magnitude more relevant than previously thought.

description: A mean field method to study heteroepitaxial thin film growth is applied to growth, intermixing and surface reconstructions of $Au$ on $Ag(110)$. The results are in accordance with experimentally observed ``burrowing'' at submonolayer coverages and growth of elongated, $(1 \times 3)$ reconstructed, $Au$ clusters at higher coverages. At coverages of few monolayers the surface between the clusters has a high concentration of $Ag$, and ordered rows of $Au$ are formed just beneath the surface.

description: The neutral current effects of the future high statistics atmospheric neutrino data can be used to distinguish the mechanisms between a $ν_μ$ oscillation to a tau neutrino or to a sterile neutrino. However, if neutrinos possess large diagonal and/or transition magnetic moments, the neutrino magnetic moments can contribute to the neutral current effects which can be studied by the single $π^0$ production events in the Super-K data. This effect should be included in the future analyses of atmospheric data in the determination of $ν_μ$ to tau or sterile neutrino oscillation.

description: This paper contributes to the question how to optimize fixed-time traffic signal coordinations for real-world applications. Therefore, two models are combined: An analytically model that optimizes fixed-time plans based on a cyclically time-expanded network formulation, and a coevolutionary transport simulation that is able to evaluate the optimized fixed-time plans for large-scale realistic traffic situations. The coupling process of both models is discussed and applied to a real-world scenario. Steps that were necessary to align the models and improve the results are presented. The optimized fixed-time signals are compared to other signal approaches in the application. It is found, that they also help to improve the performance of actuated signal control.

description: We compute the modification of the quark condensate $$ in relativistic nucleus-nucleus collisions and estimate the 4-volume, where the quark condensate is small ($/_0\leq$ 0.1--0.3) using hadron phase-space distributions obtained with the quark-gluon string model. As a function of the beam energy the 4-volume rises sharply at a beam energy $E_{lab}/A \simeq$ (2--5) GeV, remains roughly constant up to beam energies $\simeq 20$ GeV and rises at higher energies. At low energies the reduction of the condensate is mainly due to baryons, while at higher energies the rise of the 4-volume is due to the abundant mesons produced. Based on our results we expect that moderate beam energies on the order of 10 GeV per nucleon are favourable for studying the restoration of chiral symmetry in a baryon-rich environment in nucleus-nucleus collisions.

description: Matter wave interferometry is becoming an increasingly important technique in quantum metrology. However, unlike its photonic counterpart, this technique relies on the interference of particles possessing a non-zero rest mass and an electric charge. Matter waves, thus, can experience alterations in their wave-like features while propagating through uniform fields to which a linear potential can be attributed. Here, we derive analytical expressions for structured matter waves subjected to linear potentials. We show that the center of mass of corresponding to these wavefunctions follows the classical parabolic trajectory attributed to this potential and also provide the additional phase profile acquired by the wave upon propagation. Furthermore, we find that these features are identical for any structured wave, thus significantly simplifying the action of quantum effects pertaining to this potential in applications relying on structured quantum waves.

A Raysse-Style Burin and an Ornamental Fossil Shell from Heidesheim am Rhein, Germany
Creators: name: Anderson, Mark
Publisher: name: figshare
Year: 2018
Subjects: Archaeology

description: Three surface sites in the village of Heidesheim am Rhein near Mainz, Germany have each yielded a modest number of lithic artifacts which are believed to be of Upper Paleolithic age. In addition, several nonutilitarian items, including a perforated limestone pendant, a possible animal engraving, and three stone objects with anthropomorphic features, have been recovered at two of the sites. The recent discovery of a burin which closely resembles the distinctive Raysse burin of the French Gravettian has now confirmed the Upper Paleolithic attribution of the lithics and, furthermore, would seem to support the more specific proposition that the material is of Gravettian origin. Another recent find, in this case a fossil gastropod shell, can be added to the group of nonutilitarian items.

description: The Earth is impacted by 35-40 metre-scale objects every year. These meteoroids are the low mass end of impactors that can do damage on the ground. Despite this they are very poorly surveyed and characterised, too infrequent for ground based fireball bservation efforts, and too small to be efficiently detected by NEO telescopic surveys whilst still in interplanetary space. We want to evaluate the suitability of different instruments for characterising metre-scale impactors and where they come from. We use data collected over the first 3 years of operation of the continent-scale Desert Fireball Network, and compare results with other published results as well as orbital sensors. We find that although the orbital sensors have the advantage of using the entire planet as collecting area, there are several serious problems with the accuracy of the data, notably the reported velocity vector, which is key to getting an accurate pre-impact orbit and calculating meteorite fall positions. We also outline dynamic range issues that fireball networks face when observing large meteoroid entries.

description: We screened 29 strains of Neisseria gonorrhoeae and found 16/21 strains that resisted killing by normal human serum and 0/8 serum sensitive strains that bound the complement regulator, C4b-binding protein (C4bp). Microbial surface-bound C4bp demonstrated cofactor activity. We constructed gonococcal strains with hybrid porin (Por) molecules derived from each of the major serogroups (Por1A and Por1B) of N. gonorrhoeae, and showed that the loop 1 of Por1A is required for C4bp binding. Por1B loops 5 and 7 of serum-resistant gonococci together formed a negatively charged C4bp-binding domain. C4bp-Por1B interactions were ionic in nature (inhibited by high salt or by heparin), whereas the C4bp-Por1A bond was hydrophobic. Only recombinant C4bp mutant molecules containing the NH2-terminal alpha-chain short consensus repeat (SCR1) bound to both Por1A and Por1B gonococci, suggesting that SCR1 contained Por binding sites. C4bp alpha-chain monomers did not bind gonococci, indicating that the polymeric form of C4bp was required for binding. Using fAb fragments against C4bp SCR1, C4bp binding to Por1A and Por1B strains was inhibited in a complement-dependent serum bactericidal assay. This resulted in complete killing of these otherwise fully serum resistant strains in only 10% normal serum, underscoring the importance of C4bp in mediating gonococcal serum resistance.
Black-Box Problem Localization in Parallel File Systems

Year: 2015
Subjects: subject: 90699 Electrical and Electronic Engineering not elsewhere classified
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: Parallel file systems target large, high-performance storage systems. Since these storage systems
are comprised of a significant number of components (i.e., hundreds of file servers, thousands of
disks, etc.), they are expected to (and in practice do) frequently exhibit “problems”, from degraded
performance to outright failure of one or more components. The sheer number of components,
and thus, potential problems, makes manual diagnosis of these problems difficult. Of particular
concern are system-wide performance degradations, which may arise from a single misbehaving
component, and thus, pose a challenge for problem localization. Even failure of a redundant component
with a less-significant performance impact is worrisome as it may, in absence of explicit
checks, go unnoticed for some time and increase risk of system unavailability.
As a solution, this thesis defines a novel problem-diagnosis approach, capitalizing upon the
parallel-file-system design criterion of balanced performance, that peer-compares the performance
of system components to localize problems within storage systems running unmodified, “off-theshelf”
parallel file systems. Performed in support of this thesis is a set of laboratory experiments
that demonstrate proof-of-concept of the peer-comparison approach by injecting four realistic
problems into 12-server, test-bench PVFS and Lustre clusters. This thesis is further validated
by taking the diagnosis approach and adapting it to to work on a very-large, production GPFS storage
system consisting of 128 file servers, 32 storage controllers, 1152 disk arrays, and 11,520 total
disks. Presented in a 15-month case study is the problems observed through analysis of 624GB of
instrumentation data, in which a variety of performance-related storage-system problems are localized
and diagnosed, in a matter of hours, as compared to days or longer with manual approaches.
The impact of AGN on the build-up of galaxies
Creators: name: Wylezalek Dominika
Publisher: name: Zenodo

description: It is well established that AGN take an active part in shaping the way the Universe looks. In particular, AGN feedback is a key ingredient in galaxy formation models and is now widely considered to be one of the main drivers in regulating the growth and assembly of massive galaxies. In my talk I will describe several efforts in our group to understand the power, reach and impact of AGN feedback processes and how they impact the build-up of galaxies and structures across cosmic time.
 At z ~ 0.7, we have found one of the first observational evidence that AGN-driven outflows can indeed suppress star formation in their hosts, consistent with the AGN having a `negative’ impact on the galaxies' SFH. Feedback signatures seem to be best observable in gas-rich galaxies where the coupling of the AGN-driven wind to the gas is strongest, in agreement with recent simulations. However, both star formation and quasar activity peaks at z ~ 2-3 where AGN are expected to impact the build-up of stellar mass the most. Our team recently discovered a unique population of luminous high-redshift (2 < z < 4) ex- tremely red quasars (ERQs) in the SDSS-III/BOSS and WISE surveys with extreme outflow properties, including blueshifted [OIII] lines at speeds up to 6000 km/s and unusual Lya profiles. The nature of the Lya emission in ERQs is especially intriguing, as it might be tracing quiescent filaments on halo scales or dusty, very clumpy, highly accelerated gas filaments close to the nucleus. ERQs are therefore the ideal population to obtain a census of the overall mass and energy budget of both outflow and infall/feeding from the CGM, an essential requirement to probe the detailed and full feedback loop.
 Building on these results, I will also introduce the JWST ERS Program "Q3D" (PI: Wylezalek) which will make use of the IFU capabilities of NIRSpec and MIRI and through which we will study the impact of three carefully selected luminous quasars on their hosts. Our program will provide a scientific dataset of broad interest serving as a pathfinder for JWST science investigations in IFU mode.
 Finally, in the last part of my talk, I will focus on potential indirect signatures of AGN feedback on galaxy cluster scales. Our group has found that high-z radio-loud AGN trace denser environments than (radio-quiet) galaxies of the same stellar mass and potentially trace higher mass dark matter halos. Recent simulations suggest that this difference is an indirect signature of AGN feedback which impacted the build-up of the stellar component of radio galaxies which translates into different galaxies populating each environment. Testing this very interesting hypothesis is one of the next challenges.

Disclosure as a Strategy in the Patent Race
Creators: name: Mezzetti, Claudio
name: Baker, Scott
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: Abstract Research firms disclose a surprisingly large amount of information to the patent office through “targeted” disclosures, that is, disclosures intended to make the patent office aware of potentially patentable information. Conventional wisdom holds that these disclosures are made for defensive purposes; the disclosing firm does not itself plan to pursue patents related to the disclosed information, so the firm discloses to create prior art that might stop rivals from patenting. But firms have an incentive to disclose even if they intend to pursue patent protection. The reason is that, by making it more difficult to patent, disclosure extends the patent race. If an invention of a certain quality would have been sufficient to qualify for patent protection before the disclosure, after the disclosure any invention must be that much better before it will represent a sufficient advance over the now‐expanded prior art. This paper models disclosure strategies of this sort.

description: The circum-galactic medium (CGM) is the location where galaxies directly interact with their environment through accretion and feedback events. These reservoirs can cover scales of several 100s of kpc, and are mostly studied in the optical through bright emission lines such as Lyman-alpha tracing their ionized gas. However, these optical/near-IR observations are likely missing an important part of the picture. I will present ALMA observations of the atomic carbon line [CI] in a sample of nine radio galaxies at redshifts 2 to 4.5. While some of these show broad [CI] lines up to 1000 km/s likely powered by the central AGN, we also find several examples of intriguingly narrow 50-120 km/s [CI] lines in the haloes of these massive galaxies. We compare these with our VLT/MUSE observations of the same galaxies, showing that the narrow [CI] gas detected by ALMA is tracing at least as much gas the ionized gas. Our [CI] detections reach beyond the regions where the radio jets have stirred up the gas kinematics, and therefore seem to trace the elusive CGM gas reservoirs from which these massive galaxies are forming.

description: We evaluate the O(alpha_em/alpha_s) correction to the rate of B -> X_s gamma decay, i.e. we resum all the 0[ alpha_em ln M_W^2/m_b^2 x (alpha_s ln M_W^2/m_b^2)^n ] corrections for n=0,1,2,... Our calculation differs from the previously available one by that it takes into account the complete relevant set of operators. The correction is found to be negligible, i.e. it is below 1%, in accordance with the former results.

description: In this work we extend the novel framework developed by Dellnitz, Hessel-von Molo and Ziessler to the computation of finite dimensional unstable manifolds of infinite dimensional dynamical systems. To this end, we adapt a set-oriented continuation technique developed by Dellnitz and Hohmann for the computation of such objects of finite dimensional systems with the results obtained in the work of Dellnitz, Hessel-von Molo and Ziessler. We show how to implement this approach for the analysis of partial differential equations and illustrate its feasibility by computing unstable manifolds of the one-dimensional Kuramoto-Sivashinsky equation as well as for the Mackey-Glass delay differential equation.

description: There is a nascent discussion among policymakers and researchers that rural areas may be disadvantaged by their location within the supply-chain as providers of raw and minimally processed inputs to centers of production located elsewhere. This paper makes several important contributions to this emerging policy discussion. First, we formalize a new concept of intermediate circularity that characterizes the production and trade of intermediates, i.e., goods and services that are transformed and combined to produce other goods and services. Second, we use this model to derive a collection of measures that quantify the shape of economic activity. Third, we calculate feasible versions of these measures by applying the input-output framework and we compare their distribution across metro and non-metro counties of the United States. Finally, we estimate the relationship between these measures of intermediate circularity and indicators of economic performance. We find that the distributions of intermediate circularity indicators differ across metro and non-metro counties, as do their correlations with economic growth. Intermediate inputs tend to account for a larger share of output in non-metro counties and are more intensively exported. These attributes are associated with lower growth in both metro and non-metro counties. On the other hand, while using intermediate inputs is associated with growth in non-metro counties, the opposite is true in metro counties. Implications for policymakers who might consider incentivizing the spatial reorganization of economic activity with the aim of increasing rural prosperity, reducing urban-rural inequality, or improving the resilience of rural economies are discussed.
First passage statistics for diffusing diffusivity

description: A rapidly increasing number of systems is identified in which the stochastic motion of tracer particles follows the Brownian law $\langle\mathbf{r}^2(t) \rangle\simeq Dt$ yet the distribution of particle displacements is strongly non-Gaussian. A central approach to describe this effect is the diffusing diffusivity (DD) model in which the diffusion coefficient itself is a stochastic quantity, mimicking heterogeneities of the environment encountered by the tracer particle on its path. We here quantify in terms of analytical and numerical approaches the first passage behaviour of the DD model. We observe significant modifications compared to Brownian-Gaussian diffusion, in particular that the DD model may have a more efficient first passage dynamics. Moreover we find a universal crossover point of the survival probability independent of the initial condition.

Stochastic Model for the Motion of a Particle on an Inclined Rough Plane and the Onset of Viscous Friction

description: Experiments on the motion of a particle on an inclined rough plane have yielded some surprising results. For example, it was found that the frictional force acting on the ball is viscous, {\it i.e.} proportional to the velocity rather than the expected square of the velocity. It was also found that, for a given inclination of the plane, the velocity of the ball scales as a power of its radius. We present here a one dimensional stochastic model based on the microscopic equations of motion of the ball, which exhibits the same behaviour as the experiments. This model yields a mechanism for the origins of the viscous friction force and the scaling of the velocity with the radius. It also reproduces other aspects of the phase diagram of the motion which we will discuss.

description: Ammonia desorption chemical ionization of ether-linked phospholipids of the type 1-O-alkyl-2-O-acetyl-sn-glycero-3-phosphocholine (platelet-activating factors) and a series of analogues revealed a systematic fragmentation pattern that is characteristic for these compounds. The predominant ions included the protonated molecular ion and a series of fragments derived from the molecular ion having the following nominal mass losses: MH-14, MH-42, MH-59, and MH-183. Deuterated ammonia was used to elucidate the nature of several fragments. In addition, desorption chemical ionization was used to quantitate 1-O-hexadecyl-2-O-acetyl-sn-glycero-3-phosphocholine at the nanogram/sample level.

description: We study the energy structure and the transfer of an extra electron or hole along periodic polymers made of $N$ monomers, with a repetition unit made of $P$ monomers, using a Tight-Binding wire model, where a site is a monomer (e.g., in DNA, a base pair), for $P$ even, and deal with two categories of such polymers: made of the same monomer (GC..., GGCC..., etc) and made of different monomers (GA..., GGAA..., etc). We calculate the HOMO and LUMO eigenspectra, density of states and HOMO-LUMO gap and find some limiting properties these categories possess, as $P$ increases. We further examine the properties of the mean over time probability to find the carrier at each monomer. We introduce the weighted mean frequency of each monomer and the total weighted mean frequency of the whole polymer, as a measure of the overall transfer frequency content. We study the pure mean transfer rates. These rates can be increased by many orders of magnitude with appropriate sequence choice. Generally, homopolymers display the most efficient charge transfer. Finally, we compare the pure mean transfer rates with experimental transfer rates obtained by time-resolved spectroscopy.

description: Exo-zodiacal dust, exozodi for short, is warm (~300K) or hot (up to ~2000K) dust found in the inner regions of planetary systems around main sequence stars. In analogy to our own zodiacal dust, it may be located in or near the habitable zone or closer in, down to the dust sublimation distance. The study of the properties, distribution, and evolution of exozodis can inform about the architecture and dynamics of the innermost regions of planetary systems, close to their habitable zones. On the other hand, the presence of large amounts of exo-zodiacal dust may be an obstacle for future space missions aiming to image Earth-like exoplanets. The dust can be the most luminous component of extrasolar planetary systems, but predominantly emits in the near- to mid-infrared where it is outshone by the host star. Interferometry provides a unique method of separating the dusty from the stellar emission. We discuss the prospects of exozodi observations with the next generation VLTI instruments and summarize critical instrument specifications.
