description: The average age at which U.S. researchers get their first grant from NIH has increased from 34.3 in 1970, to 41.7 in 2004. These data raise the crucial question of the effects of aging on the scientific creativity and productivity of researchers. Those who worry about the aging of scientists usually believe that the younger they are the more creative and productive they will be. Using a large population of 13,680 university professors in Quebec, we show that, while scientific productivity rises sharply between 28 and 40, it increases at a slower pace between 41 and 50 and stabilizes afterward until retirement for the most active researchers. The average scientific impact per paper decreases linearly until 50-55 years old, but the average number of papers in highly cited journals and among highly cited papers rises continuously until retirement. Our results clearly show for the first time the natural history of the scientific productivity of scientists over their entire career and bring to light the fact that researchers over 55 still contribute significantly to the scientific community by producing high impact papers.

Purification and properties of dolphin muscle glutamate-oxalacetate and glutamate-pyruvate transaminases and their possible roles in the energy metabolism of diving mammals
Creators: name: Owen, Terrance George
Publisher: name: University of British Columbia
Year: 2010

description: Mitochondrial and supernatant glutamate-oxalacetate transaminases (EC 2.6.1.1) and supernatant glutamate-pyruvate transaminase (EC 2.6.1.2) were purified 89, 204 and 240-fold respectively, from dolphin muscle. Starch gel electrophoresis of crude and purified perparations revealed that all three enzymes exist as single forms. Km values of a-ketoglutarate, alanine, pyruvate and glutamate for the glutamate-pyruvate transaminase were 0.45, 8.2, 0.87 and 15 mM, respectively. For the glutamate-oxalacetate transaminases, the Km values of a-ketoglutarate, aspartate, oxalacetate and glutamate were 0.76, 0.50, 0.10 and 9.4 mM, respectively, for the mitochondrial form and 0.13, 2.4, 0.06 and 3.2 mM, respectively, for the supernatant form. In all cases, as the assay pH was decreased from pH 7.3, the Km values of the a-keto acids decreased while those of the amino acids increased. This caused the apparent equilibrium constants for the glutamate-oxalacetate transaminases to remain independent of pH. These values were 9.2 and 6.8 for the mitochondrial and supernatant forms, respectively where K'eq = [asPartate][α-ketoglutarate]/[glutamate][oxalacetate]. Studies of the inhibition of the glutamate-oxalacetate transaminases by dicarboxylic acids indicated that these enzymes may be controlled by pools of metabolic intermediates. Three key roles are suggested for the transminases in the energy metabolism of the diving mammal. First, it is believed that a combined action of the transaminases could enhance energy production during hypoxia by providing (1) fumarate from aspartate for the ATP producing reversal of succinate dehydrogenase and (2) α-ketoglutarate from glutamate for the GTP producing succinyl thiokinase reaction. Next, diving mammals probably accumulate more NADH than other mammals during hypoxia. The glutamate-oxalacetate transaminases seem particularly well suited for restoring redox balance via the malate-aspartate cycle after aerobic metabolism is resumed. Finally, since migrating divers oxidize large amounts of stored fats, the combined reactions of the transaminases could be instrumental in providing increased supplies of oxalacetate to condense with the fat derived acetyl CoA in the citrate synthase reaction.

description: Mobile and digital technologies can support learning experiences outside of the traditional
 classroom contexts and provide opportunities for collaborative elearning initiatives. Following design-based research (DBR) principles, curriculum developers face challenges in building mobile learning opportunities that are fit for purpose, adequately supported, and embraced by instructors and students alike. However, published accounts of mobile and technology-enhanced learning initiatives are currently largely restricted to ‘successes’ and lack descriptions of the processes and challenges involved in development. Critical factors for success – derived from accounts of ‘failed’ projects – may also be useful to guide the planning of initiatives in development. I present here potential steps towards a guiding framework for mobile and technology-enhanced learning developers that incorporates both an appraisal of these critical success factors within the context of a developing initiative and the instructive value of ‘productive failure’.

description: Kaon properties are studied within the framework of a fully covariant transport approach. The kaon-nucleon potential is evaluated in two schemes, a chiral perturbative approach and an effective One-Boson-Exchange model. Isospin effects are explicitly accounted for in both models. The transport calculations indicate a significant sensitivity of momentum distributions and total yields of $K^{0,+}$ isospin states on the choice of the kaon-nucleon interaction. Furthermore, isospin effects are rather moderate on absolute kaon yields, but appear on strangeness ratios. This is an important issue in determining the high density symmetry energy from studies of strangeness production in heavy-ion collisions.

description: Graphene is well known for its extraordinary mechanical properties combining brittleness and ductility. While most mechanical studies of graphene focused on the strength and brittle fracture behavior, its ductility, plastic deformation, and the possible brittle-to-ductile transition, which are important for high-temperature mechanical performance and applications, still remain much less understood. Here the mechanical response and deformation dynamics of graphene grain boundaries are investigated through a phase field crystal modeling, showing the pivotal effects of temperature and local dislocation structure. Our results indicate that even at relatively high temperature (around 3350 K), the system is still governed by a brittle fracture and cracking dynamics as found in previous low-temperature experimental and atomistic studies. We also identify another type of failure dynamics with low-angle grain boundary disintegration. When temperature increases a transition to plastic deformation is predicted. The appearance of plastic flow at ultrahigh temperature, particularly the phenomenon of jerky plasticity, is attributed to the stick and climb-glide motion of dislocations around the grain boundary. The corresponding mechanism is intrinsic to two-dimensional systems, and governed by the competition between the driving force of accumulated local stress and the defect pinning effect, without the traditional pathways of dislocation generation needed in three-dimensional materials.

description: When Germany introduced its federal statutory minimum wage of 8.50 euro in 2015, it marked a major shift in labour policy. Fast forward to 2025, and the minimum wage is now 12.82 euro. Given annual increases in the minimum wage, there are ongoing debates about how minimum wages affect income inequality. It turns out the answer depends heavily on the financial strength of the firms.

Gravity and Electroweak Symmetry Breaking in a RSI/RSII Hybrid Model

description: We present a hybrid RSI/RSII model in which we both solve the hierarchy problem and produce a continuum of KK graviton modes. In this model, four dimensional gravity can be reproduced and the radion mode can be stabilized. We then modify the hybrid gravity model to include SU(2)_L x SU(2)_R x U(1)_(B-L) bulk gauge fields. Electroweak symmetry is broken by the choice of appropriate boundary conditions. By adjusting the size of one region of the extra dimension, we show that the S parameter can be decreased while protecting the rho parameter from corrections. We find that as the S parameter is decreased by ~ 60%, M_Z' and M_W' stay below 1800 GeV, protecting unitarity.

description: Fermionic polar molecules in deep 1D optical lattices may form self-assembled filaments when the electric dipoles are oriented along the lattice axis. These composites are bosons or fermions depending on the number of molecules per chain, leading to a peculiar and complex Bose-Fermi mixture, which we discuss in detail for the simplest case of a three-well potential. We show that the interplay between filament binding energy, transverse filament modes, and trimer Fermi energy leads to a rich variety of possible scenarios ranging from a degenerate Fermi gas of trimers to a binary mixture of two different types of bosonic dimers. We study the intriguing zero temperature and finite temperature physics of these composites for the particular case of an ideal filament gas loaded in 1D sites, and discuss possible methods to probe these chain mixtures.

description: The detection of the flaring gamma-ray blazar TXS 0506+056 in spatial and temporal coincidence with the high-energy neutrino IC-170922A represents a milestone for multi-messenger astronomy. The prompt multi-wavelength coverage from several ground- and space-based facilities of this special event was enabled thanks to the key role of the $\textit{Fermi}$-Large Area Telescope (LAT), continuously monitoring the gamma-ray sky. Exceptional variable and transient events, such as bright gamma-ray flares of blazars, are regularly reported to the whole astronomical community to enable prompt multi-wavelength observations of the astrophysical sources. As soon as realtime IceCube high-energy neutrino event alerts are received, the relevant positions are searched, at multiple timescales, for gamma-ray activity from known sources and newly detected emitters positionally consistent with the neutrino localization. In this contribution, we present an overview of follow-up activities and strategies for the realtime neutrino alerts with the $\textit{Fermi}$-LAT, focusing on some interesting coincidences observed with gamma-ray sources. We will also discuss future plans and improvements in the strategies for the identification of gamma-ray counterparts of single high-energy neutrinos.

The pedagogy of Frabboni has a clear underlying theoretical model, precisely that of Bertin, but applied to the social of education and training. In thinking of Frabboni there is a massive and structural between theory and education, between school and teaching, which has shown in Frabboni one of the most committed and productive models of pedagogy. The author defines Frabboni as the authoritative voice of pedagogy from the sixties to today in light of a theoretical problem which has been constantly updated and re-read.

description: We present a preliminary analysis of the effect of dynamical friction on the orbits of part of the globular clusters in our Galaxy. Our study considers an anisotropic velocity dispersion field approximated using the results of studies in the literature. An axisymmetric Galactic model with mass components consisting of a disc, a bulge, and a dark halo is employed in the computations. We provide a method to compute the dynamical friction acceleration in ellipsoidal, oblate, and prolate velocity distribution functions with similar density in velocity space. Orbital properties, such as mean time-variations of perigalactic and apogalactic distances, energy, and z-component of angular momentum, are obtained for globular clusters lying in the Galactic region $R \lesssim$ 10 kpc, $|z| \lesssim$ 5 kpc, with $R,z$ cylindrical coordinates. These include clusters in prograde and retrograde orbital motion. Several clusters are strongly affected by dynamical friction, in particular Liller 1, Terzan 4, Terzan 5, NGC 6440, and NGC 6553, which lie in the Galactic inner region. We comment on the more relevant implications of our results on the dynamics of Galactic globular clusters, such as their possible misclassification between the categories 'halo', 'bulge', and 'thick disc', the resulting biasing of globular-cluster samples, the possible incorrect association of the globulars with their parent dwarf galaxies for accretion events, and the possible formation of 'nuclear star clusters'.

description: A broken symmetry ground state without any magnetic moments has been calculated by means of local-density-approximation to density functional theory plus a local exchange term, the so-called LDA+$U$ approach, for URu$_{2}$Si$_{2}$. The solution is analysed in terms of a multipole tensor expansion of the itinerant density matrix and is found to be a non-trivial magnetic multipole. Analysis and further calculations show that this type of multipole enters naturally in time reversal breaking in presence of large effective spin-orbit coupling and co-exists with magnetic moments for most magnetic actinides

description: In conventional public clouds, designing a suitable initial cluster for a given application workload is important in reducing the computational foot-print during run-time. In edge or on-premise clouds, cold-start rightsizing the cluster at the time of installation is crucial in avoiding the recurrent capital expenditure. In both these cases, rightsizing has to balance cost-performance trade-off for a given application with multiple tasks, where each task can demand multiple resources, and the cloud offers nodes with different capacity and cost. Multidimensional bin-packing can address this cold-start rightsizing problem, but assumes that every task is always active. In contrast, real-world tasks (e.g. load bursts, batch and dead-lined tasks with time-limits) may be active only during specific time-periods or may have dynamic load profiles. The cluster cost can be reduced by reusing resources via time sharing and optimal packing. This motivates our generalized problem of cold-start rightsizing for time-limited tasks: given a timeline, time-periods and resource demands for tasks, the objective is to place the tasks on a minimum cost cluster of nodes without violating node capacities at any time instance. We design a baseline two-phase algorithm that performs penalty-based mapping of task to node-type and then, solves each node-type independently. We prove that the algorithm has an approximation ratio of O(D min(m, T)), where D, m and T are the number of resources, node-types and timeslots, respectively. We then present an improved linear programming based mapping strategy, enhanced further with a cross-node-type filling mechanism. Our experiments on synthetic and real-world cluster traces show significant cost reduction by LP-based mapping compared to the baseline, and the filling mechanism improves further to produce solutions within 20% of (a lower-bound to) the optimal solution.

Studies on antigen binding cells involved in cellular immunity to ferredoxin peptides
Creators: name: Pearson, Terry W.
Publisher: name: University of British Columbia
Year: 2010

description: Previous studies with conjugates containing the NH2-terminal and COOH-terminal antigenic determinants of oxidized ferredoxin from C. pasteurianum indicated a need for at least two determinants to stimulate DNA synthesis in sensitized lymphocytes. This suggested a mechanism involving cell cooperation, a possibility which has been investigated here by selectively inactivating cells binding one or the other of the determinants. Cells from immunized guinea pigs were tested in vitro for their capacity to bind antigen or to be stimulated by it before and after "antigen suicide" with radioiodinated conjugates containing the NH2-terminal or COOH-terminal determinants of oxidized ferredoxin. A microculture system for assessing antigen induced stimulation of 3H-thymidine uptake by lymphocytes was developed for this work. The data show that: 1) Lymphocytes from unimmunized guinea pigs bind both NH2-terminal and COOH-terminal determinants at a frequency of about 10-4. In immune animals the proportion of antigen binding cells increased about 4-6 fold. The frequency of cells binding the determinants depends markedly on the specific activity of antigens employed. 2) Both T and B lymphocytes bind the antigenic determinants from oxidized ferredoxin. 3) Specific inactivation of cells binding either determinant was achieved by antigen suicide with ¹²⁵I-NH₂-terminal or ¹²⁵I COOH-terminal s-BSA conjugates. Synergy occurs between the NH2-terminal binding cells and COOH-terminal binding cells in the proliferative response of sensitized lymph node cells challenged with oxidized ferredoxin in vitro. Evidence from B cell depletion studies indicates that this is a T cell-T cell interaction.

The evolution curves for the baryon number density, baryon number susceptibility, pressure and the equation of state are obtained. The chiral condensate is calculated and our result shows that when the baryon chemical potential goes beyond $1150 \mathrm{MeV}$, the absolute value of the quark condensate decreases rapidly, which indicates a tendency of chiral restoration.

description: We present the results of a kinematic study of planetary nebulae in the extreme outskirts of two spiral galaxies, M83 (NGC 5236) and M94 (NGC 4736). We find that in the inner regions of the galaxies, the vertical velocity dispersion (sigma_z) falls off exponentially with the light, as expected for a constant mass-to-light ratio, constant thickness disk. However, starting at four optical scale lengths, sigma_z asymptotes out at roughly 20 km/s. Our analysis finds evidence for significant flaring in the outer regions as well, especially in M94. These observations are in excellent agreement with predictions derived from models of disk heating by halo substructure, and demonstrate how kinematic surveys in the outer disks of spirals can be used to test hierarchical models of galaxy formation.

description: Online learning is making it difficult to have honest and fair exams. In a regular classroom, teachers can observe students as they take tests and online this is far more difficult. Students could search for answers or consult others without anyone ever knowing. Smart Exam Management System implements the new tech solutions to implement a safe environment for exams. It verifies that the person is indeed the student and it looks for any other people in the room. The system prevents students from diversifying their attention to other apps during the examination and notifies teachers if the student wants to redirect and copy answers by switching tabs. The exam gets automatically submitted if it runs out of time, or if cheating is detected. This solution has a very powerful backend system which manages all the rules and saves information securely to ensure fair online exams, reduce teacher workload in terms of evaluation & at the same time boost exam confidence as educators can trust their grading.
Corporate Social Responsibility Practices in the Retail sector: a Multiple Case Study Analysis of US Retailers

Year: 2021

description: Over the last few years, Corporate Social Responsibility (CSR) has become a central theme in corporate management and is a relevant element of competitiveness for businesses. However, it is difficult to find a sustainable business model that fits perfectly to all companies, therefore, the aim of this study is to analyze the social responsibility balances of some of the major American companies in the retail sector through a multiple case study analysis, to verify similarities and differences in their approach to defining a socially responsible strategy. The methodology used is a multiple case study analysis that compares the Social Reports of 5 American companies selected as a sample as they are leaders in the Retail sector, considering the Deloitte rankings. The commitment on the social and environmental front of companies considered is aimed at producing long-term collective benefits and is not reduced to formal and facade interventions adopted in the short term mainly for opportunistic purposes. Sometimes companies consider sustainability as a goal to be achieved, but from the results of the study, analyzing the different time period 2012-2018, it can be seen that it is not an achievable goal, but a prolonged path, during which the company and its stakeholders try to improve each other continuously.

description: We reconstruct an explicit model of modified gravity in which a crossing of the phantom divide can be realized. It is shown that the (finite-time) Big Rip singularity appears in the model of modified gravity (i.e., in the so-called Jordan frame), whereas that in the corresponding scalar field theory obtained through the conformal transformation (i.e., in the so-called Einstein frame) the singularity becomes the infinite-time one. Furthermore, we investigate the relations between the scalar field theories with realizing a crossing of the phantom divide and the corresponding modified gravitational theories by using the inverse conformal transformation. It is demonstrated that the scalar field theories describing the non-phantom phase (phantom one with the Big Rip) can be represented as the theories of real (complex) $F(R)$ gravity through the inverse (complex) conformal transformation. We also study a viable model of modified gravity in which the transition from the de Sitter universe to the phantom phase can occur. In addition, we explore the stability for the obtained solutions of the crossing of the phantom divide under a quantum correction coming from conformal anomaly.

L’umiltà come virtù e i problemi da risolvere

description: Il dibattito intorno alla nozione di umiltà come virtù è quanto mai acceso. Questo articolo si propone di evidenziare i progressi della recente discussione filosofica sull’umiltà a partire dalle considerazioni offerte nei lavori sul tema di Mario Micheletti. In particolare, l’articolo discute due concezioni dell’umiltà come virtù: la concezione doxastica, che intende l’umiltà come sottostima dei propri meriti o come consapevolezza di sé e dei propri limiti, e la concezione non-doxastica, secondo cui l’umiltà è l’atteggiamento di noncuranza che il virtuoso ha nei confronti delle proprie qualità e dei propri successi. Dopo aver analizzato tre problemi a cui qualsiasi concezione dell’umiltà deve rispondere e aver discusso la tesi secondo cui la concezione non-doxastica, a differenza della visione rivale, sarebbe in grado di risolvere i problemi in questione, offro alcune ragioni per preferire un terzo approccio, che attinge da entrambe le concezioni i requisiti necessari per definire l’umiltà come virtù.

description: We demonstrate that, in a multi-BMPV black hole spacetime, the event horizon is not smooth. We explicitly show that for a simpler configuration comprising a line of static extremal black holes and a single BMPV black hole, the metric at the horizon of the BMPV black hole is once, but not twice, continuously differentiable. We argue that this result is also valid when all the black holes are rotating. The Maxwell field strength is shown to be continuous, but not differentiable at the horizon. We also briefly demonstrate that previous work done to show lack of smoothness of static multi-centre solutions in five dimensions is not significantly modified by the inclusion of a higher derivative term in the action for five dimensional supergravity.

description: We propose a new radial coordinate to write the Kerr metric in puncture form. Unlike the quasi-radial coordinate introduced previously, the horizon radius remains finite in our radial coordinate in the extreme Kerr limit a/M -> 1. This significantly improves the accuracy of the evolution of black holes with spins close to the extreme Kerr limit. We are able to evolve accurately both stationary and boosted black holes with spins as high as a/M=0.99 using initial data constructed in these new puncture coordinates. Initial data of compact binaries with rapidly spinning black holes can be constructed using our proposed new puncture metric for the background conformal metric. Our simulations for single black holes suggest that such initial data can be evolved successfully by the moving puncture technique.

description: Ram pressure stripping of galaxies in clusters can yield gas deficient disks. Previous numerical simulations based on various approaches suggested that, except for near edge-on disk orientations, the amount of stripping depends very little on the inclination angle. Following our previous study of face-on stripping, we extend the set of parameters with the disk tilt angle and explore in detail the effects of the ram pressure on the interstellar content (ISM) of tilted galaxies that orbit in various environments of clusters, with compact or extended distributions of the intra-cluster medium (ICM). We further study how results of numerical simulations could be estimated analytically. A grid of numerical simulations with varying parameters is produced using the tree/SPH code GADGET with a modified method for calculating the ISM-ICM interaction. These SPH calculations extend the set of existing results obtained from different codes using various numerical techniques. The simulations confirm the general trend of less stripping at orientations close to edge-on. The dependence on the disk tilt angle is more pronounced for compact ICM distributions, however it almost vanishes for strong ram pressure pulses. Although various hydrodynamical effects are present in the ISM-ICM interaction, the main quantitative stripping results appear to be roughly consistent with a simple scenario of momentum transfer from the encountered ICM. This behavior can also be found in previous simulations. To reproduce the numerical results we propose a fitting formula depending on the disk tilt angle and on the column density of the encountered ICM. Such a dependence is superior to that on the peak ram pressure used in previous simple estimates.

description: The study of Galactic diffuse $γ$ radiation combined with the knowledge of the distribution of the molecular hydrogen in the Galaxy offers a unique tool to probe the cosmic ray flux in the Galaxy. A methodology to study the level of the cosmic ray "sea" and to unveil target-accelerator systems in the Galaxy, which makes use of the data from the high resolution survey of the Galactic molecular clouds performed with the NANTEN telescope and of the data from gamma-ray instruments, has been developed. Some predictions concerning the level of the cosmic ray "sea" and the $γ$-ray emission close to cosmic ray sources for instruments such as Fermi and Cherenkov Telescope Array are presented.

description: We use ideal axisymmetric relativistic magnetohydrodynamic simulations to calculate the spindown of a newly formed millisecond, B ~ 10^{15} G, magnetar and its interaction with the surrounding stellar envelope during a core-collapse supernova (SN) explosion. The mass, angular momentum, and rotational energy lost by the neutron star are determined self-consistently given the thermal properties of the cooling neutron star's atmosphere and the wind's interaction with the surrounding star. The magnetar drives a relativistic magnetized wind into a cavity created by the outgoing SN shock. For high spindown powers (~ 10^{51}-10^{52} ergs/s), the magnetar wind is super-fast at almost all latitudes, while for lower spindown powers (~ 10^{50} erg/s), the wind is sub-fast but still super-Alfvenic. In all cases, the rates at which the neutron star loses mass, angular momentum, and energy are very similar to the corresponding free wind values (

description: Religion is a form of the culture, that today we know in his structure and in his function. From experience of sacred religion is became culture of membership, but also of faith. Faith like hope, lived personally. But today also like plural faith: in God or in the human universal values. Theological or secular. And in this pluralism of faiths, today, we have to form ourselves.

description: This work examines the finite temperature properties of the CPT-even and parity-odd electrodynamics of the standard model extension. We start from the partition function written into the functional integral formalism in Ref. \cite{Finite}. After specializing the Lorentz-violating tensor $ W_{ανρφ}$ for the nonbirefringent and parity-odd coefficients, the partition function is explicitly carry out, showing that it is a power of the Maxwell's partition function. Also, it is observed that the LIV coefficients induce an anisotropy in the black body angular energy density distribution. The Planck's radiation law retains its usual frequency dependence and the Stefan-Boltzmann law keeps the same form, except for a global proportionality constant.
