PRICE’S LAW
SCIENCE GROWTH

description: Price’s law of exponential growth holds for the Journal of Molecular Biology (JMB), a journal created in 1959 and which was arguably at that time the most important of the discipline. In this paper, this growth is detailed according to countries, scientists, topics, at the early stage of the history of the journal, from 1959 to the 1970s, thanks to databases (Scopus, Pudmed) as well as manual analysis. The aim of the paper is to check whether in several subfields of molecular biology, Price’s views on the relationship between little science (at the scientist level) and big science (from the statistical point of view) are fruitful. During this period, which by some scientists has been considered as the “golden age” of molecular biology, important scientific problems were solved (genetic code, DNA replication) and in the 1970s, their applications -genetic engineering technologyemerged. The growth of the journal was exponential, as expected by Price’s law, but outpaced the prediction, with a shorter doubling-time than 15 years. Thus, JMB is a suitable case for a more detailed analysis of its scientific content and of the relationship between statistical growth and scientific trends at the bench.

CONDITIONS FOR LEADERSHIP

description: The purpose of the study is to identify the interest of young professionals to work in the field of science and innovation, as well as the necessary conditions for realization of their leadership potential in the employment behavior and in interaction with the authorities.The theoretical understanding of the behaviour and leadership opportunities for youth is based, first, on the approach of D. McClelland, under which labor activity, its result is determined by the interaction of three variables: motives, personal capabilities and qualities. Second, on the theory of expectations of V. Vroom studying work motivation. Thirdly, on the theories of positive leadership, in particular used the concept of distributed leadership by D. Bradford and A. Cohen, and terms and the conditions of group leadership of N. Tichy.Using data from a survey of graduates conducted in 2015-2016, IEIE SB RAS (2573 respondents) identified the motives of choice of profession graduates and their preferred areas of employment. Shown significant differences in motivation between those who want to work in the field of science and innovations and those aimed at other areas of employment.Data from the all-Russia surveys of young scientists and innovators, conducted in 2003-2004, 2010 and 2011 (1192, 1328 and 1032 respondents, respectively), allowed to characterize leadership resource of youth and the prerequisites of successful leadership. It is proved that the role of young scientists in the innovative development should be strengthened by granting them more resources and responsibility for decision making.

description: This article presents the results of a survey of Russian and French scientists, which has been conducted via face-to-face interviews, to identify motivations, origins, and a pace of development for scientific collaborations between the two countries. Respondents had experience in different types of interactions, including participation in joint research projects, fellowships, and part-time work in partner’s lab. The major obstacle for these collaborations is the lack of funding, some logistical problems, with other issues related to the specifics of organization and regulation of scientific research in Russia. Sanctions and the state of foreign affairs also affect collaborations, even if indirectly. However, despite the existing obstacles, both parties are willing to continue joint work. Most of the findings of this study, which appeared to be more specific to science disciplines than to Russian-French relations, are likely to be applicable to the understanding of collaborations between the Russian and EU scientists in general.

description: This study investigates students’ views of science and technology, taking into consideration both internal and external factors. The article reports on the perceptions of 3,503 Italian students, focussing mainly on individual interests, scholastic experiences and their opinions concerning science and technology. A further analysis deals with the degree to which young people may consider following a career in scientific sectors. Findings show that although wider interests would tend to support future decisions, students appear to nurture ambivalent attitudes towards scientific careers. It is suggested that with respect to different levels of personal achievement in scientific careers various factors may have influenced the initial orientation. Such factors include the academic qualifications held by the students’ parents and the presence of science laboratories at the schools they have attended. These variables moreover only appear to affect a student’s intention to seek admission to a science faculty. In the presence of an intention to embark on a scientific career following graduation certain significant elements come into play, such as their participation in scientific events, the chance to come into direct contact with researchers and their confidence in scientific studies. If a student presents a desire to become a scientist, the degree of confidence that is felt with respect to this particular sphere also becomes significant. The pleasure in studying science subjects is the most influential variable, but its effect is reduced over the three stages of the envisaged or planned path.

description: The concept of governmental financing of science and technology was born in the Western World as early as the 17th Century. Both Great Britain and France became aware of the need to protect and enhance the scientific achievements of their scientists, mainly for reasons of international prestige. The USA witnessed a spectacular growth of its scientific facilities in the 20th Century. The number of National Laboratories expanded out of the massive scientific effort developed during WWII that produced innovative technologies such as the radar, the computer, the proximity fuse and, unfortunately, the atomic bomb. The scale and impact of the mobilization of science for military purposes during WW II was extraordinary and unprecedented. The concept of National Laboratory gradually extended in the USA to include research institutions dedicated to areas of national interest like atmosphere, soil, oceans and health of the population. Although not necessarily identified as National Laboratories, they conserved the characteristic of being financed by the national government. Countries in the process of development have put a lot of interest in the creation and support of National Laboratories, or equivalents, as a strategy to enhance productivity and reduce the gap between developed and developing countries. The chain science─technology─innovation─applications is to be encouraged for both international prestige and increase in revenues at national and international levels. The federal agency that is in charge of planning and implementing Mexican science, technology and innovation policy is the National Council for Science and Technology (Conacyt, in Spanish). In 2006, the institution launched a National Laboratories program through a call for national laboratory candidates that is still in effect today. The applicants submit a project to Conacyt, and commit to the joint development of projects with one or more similar Mexican research institutions. Those who are approved are supported with funds to acquire necessary equipment. Conacyt’s ultimate aim is for the laboratories to become self-sufficient with the provision of services, as well as national and international referents in their field of knowledge. A preliminary presentation of a successful Mexican National Laboratory, the National Center of Imaging Studies and Medical Instrumentation (CI3M), is presented as a paradigmatic example of the track laboratories in the program should follow, aimed at accomplishing satisfactorily the objectives of human resource development, production of innovative technology, and provision of services. CI3M not only has fulfilled such areas but has become self-sufficient through the provision of services and the creation of their own enterprises.

description: We analyze the resurgence properties of finite-dimensional exponential integrals which are prototypes for partition functions in quantum field theories. In these simple examples, we demonstrate that perturbation theory, even at arbitrarily weak coupling, fails as the argument of the coupling constant is varied. It is well-known that perturbation theory also fails at stronger coupling. We show that these two failures are actually intimately related. The formalism of resurgent transseries, which takes into account global analytic continuation properties, fixes both problems, and provides an arbitrarily accurate description of exact result for any value of coupling. This means that strong coupling results can be deduced by using merely weak coupling data. Finally, we give another perspective on resurgence theory by showing that the monodromy properties of the weak coupling results are in precise agreement with the monodromy properties of the strong-coupling expansions, obtained using analysis of the holomorphy structure of Picard-Fuchs equations.

description: In this paper we consider the implications of the distributions of dust and metals in the disc of M31. We derive mean radial dust distributions using a dust map created from Herschel images of M31 sampling the entire far-infrared (FIR) peak. Modified blackbodies are fit to approximately 4000 pixels with a varying, as well as a fixed, dust emissivity index (beta). An overall metal distribution is also derived using data collected from the literature. We use a simple analytical model of the evolution of the dust in a galaxy with dust contributed by stellar sources and interstellar grain growth, and fit this model to the radial dust-to-metals distribution across the galaxy. Our analysis shows that the dust-to-gas gradient in M31 is steeper than the metallicity gradient, suggesting interstellar dust growth is (or has been) important in M31. We argue that M31 helps build a case for cosmic dust in galaxies being the result of substantial interstellar grain growth, while the net dust production from stars may be limited. We note, however, that the efficiency of dust production in stars, e.g., in supernovae (SNe) ejecta and/or stellar atmospheres, and grain destruction in the interstellar medium (ISM) may be degenerate in our simple model. We can conclude that interstellar grain growth by accretion is likely at least as important as stellar dust production channels in building the cosmic dust component in M31.

description: We develop a new method to account for the finite lifetimes of stars and trace individual abundances within a semi-analytic model of galaxy formation. At variance with previous methods, based on the storage of the (binned) past star formation history of model galaxies, our method projects the information about the metals produced by each simple stellar population (SSP) in the future. Using this approach, an accurate accounting of the timings and properties of the individual SSPs composing model galaxies is possible. We analyse the dependence of our chemical model on various ingredients, and apply it to six simulated haloes of roughly Milky Way mass and with no massive close neighbour at z=0. For all models considered, the [Fe/H] distributions of the stars in the disc component are in good agreement with Milky Way data, while for the spheroid component (whose formation we model only through mergers) these are offset low with respect to observational measurements for the Milky Way bulge. This is a consequence of narrow star formation histories, with relatively low rates of star formation. The slow recycling of gas and energy from supernovae in our chemical model has important consequences on the predicted star formation rates, which are systematically lower than the corresponding rates in the same physical model but with an instantaneous recycling approximation. The halo that resembles most our Galaxy in terms of its global properties also reproduces the observed relation between the average metallicity and luminosity of the Milky Way satellites, albeit with a slightly steeper slope.

description: This contribution describes some recent advances in the parallelization of the generation and processing of radio signals emitted by particle showers in CORSIKA 8. CORSIKA 8 is a Monte Carlo simulation framework for modeling ultra-high energy particle cascades in astroparticle physics. The aspects associated with the generation and processing of radio signals in antennas arrays are reviewed, focusing on the key design opportunities and constraints for deployment of multiple threads on such calculations. The audience is also introduced to Gyges, a lightweight, header-only and flexible multithread self-adaptive scheduler written compliant with C++17 and C++20, which is used to distribute and manage the worker computer threads during the parallel calculations. Finally, performance and scalability measurements are provided and the integration into CORSIKA 8 is commented.
Performance of the ATLAS muon trigger in pp collisions at $\sqrt{s}=8$ TeV

Year: 2014
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: The performance of the ATLAS muon trigger system is evaluated with proton-proton collision data collected in 2012 at the Large Hadron Collider at a centre-of-mass energy of 8 TeV. It is primarily evaluated using events containing a pair of muons from the decay of $Z$ bosons. The efficiency of the single-muon trigger is measured for muons with transverse momentum 25 < $p_T$ < 100 GeV, with a statistical uncertainty of less than 0.01% and a systematic uncertainty of 0.6%. The $p_T$ range for efficiency determination is extended by using muons from decays of $J/ψ$ mesons, $W$ bosons, and top quarks. The muon trigger shows highly uniform and stable performance. The performance is compared to the prediction of a detailed simulation.

A new approach to curved projective superspace
Creators: name: Butter, Daniel
Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We present a new formulation of curved projective superspace. The 4D N=2 supermanifold M^{4|8} (four bosonic and eight Grassmann coordinates) is extended by an auxiliary SU(2) manifold, which involves introducing a vielbein and related connections on the full M^{7|8} = M^{4|8} x SU(2). Constraints are chosen so that it is always possible to return to the central gauge where the auxiliary SU(2) manifold largely decouples from the curved manifold M^{4|8} describing 4D N=2 conformal supergravity. We introduce the relevant projective superspace action principle in the analytic subspace of M^{7|8} and construct its component reduction in terms of a five-form J living on M^4 x C, with C a contour in SU(2). This approach is inspired by and generalizes the original approach taken in arXiv:0805.4683 and related works, which can be identified with a complexified version of the central gauge of the formulation presented here.

description: Using dynamical density functional theory we calculate the speed of solidification fronts advancing into a quenched two-dimensional model fluid of soft-core particles. We find that solidification fronts can advance via two different mechanisms, depending on the depth of the quench. For shallow quenches, the front propagation is via a nonlinear mechanism. For deep quenches, front propagation is governed by a linear mechanism and in this regime we are able to determine the front speed via a marginal stability analysis. We find that the density modulations generated behind the advancing front have a characteristic scale that differs from the wavelength of the density modulation in thermodynamic equilibrium, i.e., the spacing between the crystal planes in an equilibrium crystal. This leads to the subsequent development of disorder in the solids that are formed. For the one-component fluid, the particles are able to rearrange to form a well-ordered crystal, with few defects. However, solidification fronts in a binary mixture exhibiting crystalline phases with square and hexagonal ordering generate solids that are unable to rearrange after the passage of the solidification front and a significant amount of disorder remains in the system.

description: We use fidelity susceptibility to calculate quantum critical scaling exponents for a system consisting of $N$ identical bosons interacting with a single impurity atom in a double well potential (bosonic Josephson junction). Above a critical value of the boson-impurity interaction energy there is a spontaneous breaking of $\mathbb{Z}_2$ symmetry corresponding to a second order quantum phase transition from a balanced to an imbalanced number of particles in either the left or right hand well. We show that the exponents match those in the Lipkin-Meshkov-Glick and Dicke models suggesting that the impurity model is in the same universality class. The phase transition can be interpreted as a measurement of the position of the impurity by the bosons.

description: “PostNauka” is a project (quite similar to the global set of conferences “TED”) about modern fundamental science and the scientists who create it. The website was established in 2012 as a platform, participating in the popularization of scientific knowledge. More than 3000 materials were published on it. Surprisingly, no one has tried to carry out the analysis of these materials until now. We decided to fill this gap by conducting our own research on PostNauka. An inspiring example to be followed was the performance by Sean Gourley and Eric Berlow, who showed the map of themes similarity in the TED-speeches and the way new topics were born on the periphery of global themes. We conducted the same type of analysis for PostNauka to show the existence or the lack of links between topics, to define the extent of interdisciplinarity of the project and to check the rightness of sections proposed by the website. We took all video-materials transcripts published on www.postnauka. ru. Two types of methods were combined for analysis: semantic analysis methods and network analysis. As a result, we got the mind-maps of PostNauka materials. They demonstrate how the materials are tied, which disciplines are exceled and how they are sorting with the official classification of the website.
Flow reversals in turbulent convection with free-slip walls

description: We perform numerical simulations of turbulent convection for infinite Prandtl number with free-slip walls, and study the dynamics of flow reversals. We show interesting correlations between the flow reversals and the nonlinear interactions among the large-scale flow structures represented by the modes $(1,1), (2,1), (3,1)$ and some others. After a flow reversal, the odd modes, e.g. $(1,1), (3,1)$, switch sign, but the even modes, e.g. $(2,2)$, retain their sign. The mixed modes $(1,2)$ and $(2,1)$ fluctuate around zero. Using the properties of the modes and their interactions, we show that they form a Klein four-group $Z_2 \times Z_2$. We also show that for the free-slip boundary condition, the corner rolls and vortex reconnection are absent during a flow reversal, in contrast to active role played by them in flow reversals for the no-slip boundary condition. We argue that the flow reversals with the no-slip and free-slip boundary conditions are different because they are induced by nonlinearities $ ({\bf u} \cdot \nabla) {\bf u}$ and $({\bf u} \cdot \nabla) θ$ respectively.

title: Alkaline phosphatase functionalized nanoparticles: attachment, enzyme kinetics and colloidal diffusion
Creators: name: Alhasanat, Anas
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Enzymes are proteins found in organisms that work as biological catalysts. In the last decade, some studies report that enzymes diffuse faster during catalysis [1], and recently others show the possibility of making enzyme-powered micromotors; where urease-functionalized microparticles appear to diffuse faster during catalysis as observed by trajectory tracking [2]. We studied the validity of using the enzyme alkaline phosphatase as a nanomotor on spherical polystyrene particles with a diameter of 200 nm (attached by glutaraldehyde coupling) using differential dynamic microscopy (DDM) and dynamic light scattering (DLS) to obtain the diffusion coefficient of those particles compared to bare particles of the same size looking for any enhanced particles motion. We will report on the existence (or absence) of enhancement in diffusivity. The enzyme activity of our alkaline phosphatase functionalized nanoparticles, obtained by spectroscopy and the Michaelis-Menten relation [3], was found to be very similar (slightly lower) to the bare alkaline phosphatase activity. DDM is a technique that exploits optical microscopy to obtain local quantitative information about dynamic samples (diffusion coefficient, particle size) by probing wave vector-dependent dynamics [4]. DDM could be used to study the dynamics in liquid suspensions, soft materials, cells, and tissues. In DDM, image sequences are analyzed via a combination of image differences and spatial Fourier transforms to obtain information equivalent to that obtained by means of dynamic light scattering (DLS) techniques. Compared to DLS and particle trajectory tracking, DDM offers obvious advantages, most importantly, providing high statistics by capturing a large number of particles, removing the static contributions along the optical path, flexibility of choosing an analysis region, and the power of simultaneous different microscopy contrast mechanisms. But those advantages come with a price; it is challenging to know the suitable settings (camera speed, objective magnification, sample dilution, etc.) for each measurement (i.e., each particle size). In order to validate our DDM setup, we studied a range of polystyrene particles size (60 nm-1 micron) suspended in water using different settings to conclude the suitable settings for each size in that range. Using previously published Python code [5] and modified by our group, we managed to analyze thousands of frames (images) with the speed of hundreds of frames per second for each measurement. All measurements were compared to DLS measurements on the same samples (but more diluted) for comparison.
Backreaction effects due to matter coupled higher derivative gravity

description: AdS-hydrodynamics has proven to be a useful tool for obtaining transport coefficients observed in the collective flow of strongly coupled fluids like quark gluon plasma (QGP). Particularly, the ratio of shear viscosity to entropy density ${η/ s}$ obtained from elliptic flow measurements can be matched with the computation done in the dual gravity theory. The experimentally observed temperature dependence of ${η/ s}$ requires the study of scalar matter coupled AdS gravity including higher derivative curvature corrections. We obtain the backreaction to the metric for such a matter coupled AdS gravity in $D$-dimensional spacetime due to the higher derivative curvature corrections. Then, we present the backreaction corrections to shear-viscosity $η$ and entropy density $s$.

description: The dual-fermion approach offers a way to perform diagrammatic expansion around the dynamical mean-field theory. Using this formalism, the influence of antiferromagnetic fluctuations on the self-energy is taken into account through ladder-type diagrams in the particle-hole channel. The resulting phase diagram for the (quasi-)two-dimensional Hubbard model exhibits antiferromagnetism and d-wave superconductivity. Furthermore, a uniform charge instability, i.e., phase separation, is obtained in the low doping regime around the Mott insulator. We also examine spin/charge density wave fluctuations including d-wave symmetry. The model exhibits a tendency towards an unconventional charge density-wave, but no divergence of the susceptibility is found.

description: We consider Approval Voting systems where each voter decides on a subset to candidates he/she approves. We focus on the optimization problem of finding the committee of fixed size k minimizing the maximal Hamming distance from a vote. In this paper we give a PTAS for this problem and hence resolve the open question raised by Carragianis et al. [AAAI'10]. The result is obtained by adapting the techniques developed by Li et al. [JACM'02] originally used for the less constrained Closest String problem. The technique relies on extracting information and structural properties of constant size subsets of votes.

description: We study the dynamics of spin currents in the XX spin-1/2 ladder at finite temperature. Within the framework of linear response theory, we numerically calculate autocorrelation functions for quantum systems larger than what is accessible with exact diagonalization using the concept of dynamical quantum typicality. We show that spin Drude weights vanish exponentially fast with increasing system size. As a main result, we unveil qualitatively different dependencies of the spin diffusion coefficient on the rung-interaction strength, resulting from a crossover from exponential to Gaussian dissipation as the rung coupling increases. This behavior is also derived analytically. We further discuss the relation of our results to experiments with cold atomic gases.

description: It is proved that the resolvent norm of an operator with a compact resolvent on a Banach space $X$ cannot be constant on an open set if the underlying space or its dual is complex strictly convex. It is also shown that this is not the case for an arbitrary Banach space: there exists a separable, reflexive space $X$ and an unbounded, densely defined operator acting in $X$ with a compact resolvent whose norm is constant in a neighbourhood of zero; moreover $X$ is isometric to a Hilbert space on a subspace of co-dimension $2$. There is also a bounded linear operator acting on the same space whose resolvent norm is constant in a neighbourhood of zero. It is shown that similar examples cannot exist in the co-dimension $1$ case.

On the cause of solar-like equatorward migration in global convective dynamo simulations

description: We present results from four convectively-driven stellar dynamo simulations in spherical wedge geometry. All of these simulations produce cyclic and migrating mean magnetic fields. Through detailed comparisons we show that the migration direction can be explained by an $αΩ$ dynamo wave following the Parker--Yoshimura rule. We conclude that the equatorward migration in this and previous work is due to a positive (negative) $α$ effect in the northern (southern) hemisphere and a negative radial gradient of $Ω$ outside the inner tangent cylinder of these models. This idea is supported by a strong correlation between negative radial shear and toroidal field strength in the region of equatorward propagation.

description: In this paper, we study a global bifurcation of codimension one connected with the disappearance (for positive values of a parameter μ) of a saddle-node periodic orbit L0 under the condition that all orbits from the locally unstable manifold Wu of L0 tend to L0 as t → +∞. Conditions are presented which guarantee the blue sky catastrophe: the appearance of a stable periodic orbit Lμ which exists for any small positive values of μ but its length and period unboundedly increase as μ → + 0.

Brachyura
freshwater crabs
gene-tree discordance
ILS

description: Despite extensive morphological and molecular studies, the phylogenetic interrelationships within the infraorder Brachyura and the phylogenetic positions of many taxa remain uncertain. Studies that used a limited number of molecular markers have often failed to provide sufficient resolution and may be susceptible to stochastic errors and incomplete lineage sorting (ILS). Here we reconstructed the phylogenetic relationships within the Brachyura using transcriptome data of 56 brachyuran species, including 14 newly sequenced taxa. Five supermatrices were constructed in order to exclude different sources of systematic error. The results of the phylogenetic analyses indicate that Heterotremata is non-monophyletic and that the two Old World primary freshwater crabs (Potamidae and Gecarcinucidae) and the Hymenosomatoidea form a clade that is sister to the Thoracotremata, and outside the Heterotremata. We also found that ILS is the main cause of the gene-tree discordance of these freshwater crabs. Divergence time estimations indicate that the Brachyura has an ancient origin, probably either in the Triassic or Jurassic, and that the majority of extant families and superfamilies first appeared during the Cretaceous, with a constant increase of diversity in Post-Cretaceous-Palaeogene times. The results support the hypothesis that the two Old World freshwater crab families included in this study (Potamidae and Gecarcinucidae) diverged from their marine ancestors around 120 Ma, in the Cretaceous. In addition, this work provides new insights that may aid in the reclassification of some of the more problematic brachyuran groups.

Changes in rotational characters of one- and two-phonon $γ$-vibrational bands in $^{105}$Mo
Creators: name: Matsuzaki, Masayuki
Publisher: name: arXiv
Year: 2014
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The $γ$ vibration is the most typical low-lying collective motion prevailing the nuclear chart. But only few one-phonon rotational bands in odd-$A$ nuclei have been known. Furthermore, two-phonon states, even the band head, have been observed in a very limited number of nuclides not only of odd-$A$ but even-even. Among them, that in $^{105}$Mo is unique in that Coriolis effects are expected to be stronger than in $^{103}$Nb and $^{105}$Nb on which theoretical studies were reported. Then the purpose of the present work is to study $^{105}$Mo paying attention to rotational character change of the one-phonon and two-phonon bands. The particle-vibration coupling model based on the cranking model and the random-phase approximation is used to calculate the vibrational states in rotating odd-$A$ nuclei. The present model reproduces the observed yrast zero-phonon and one-phonon bands well. Emerging general features of the rotational character change from low spin to high spin are elucidated. In particular, the reason why the one-phonon band does not exhibit signature splitting is clarified. The calculated collectivity of the two-phonon states, however, is located higher than observed.
