description: In recent times, there have been a lot of efforts for improving the ossified Internet architecture in a bid to sustain unstinted growth and innovation. A major reason for the perceived architectural ossification is the lack of ability to program the network as a system. This situation has resulted partly from historical decisions in the original Internet design which emphasized decentralized network operations through co-located data and control planes on each network device. The situation for wireless networks is no different resulting in a lot of complexity and a plethora of largely incompatible wireless technologies. The emergence of "programmable wireless networks", that allow greater flexibility, ease of management and configurability, is a step in the right direction to overcome the aforementioned shortcomings of the wireless networks. In this paper, we provide a broad overview of the architectures proposed in literature for building programmable wireless networks focusing primarily on three popular techniques, i.e., software defined networks, cognitive radio networks, and virtualized networks. This survey is a self-contained tutorial on these techniques and its applications. We also discuss the opportunities and challenges in building next-generation programmable wireless networks and identify open research issues and future research directions.

Proton velocity ring-driven instabilities and their dependence on the ring speed: Linear theory
Creators: name: Min, Kyungguk

Publisher: name: Auburn University
Year: 2017

description: Linear dispersion theory is used to study the Alfven-cyclotron, mirror and ion Bernstein instabilities driven by a tenuous (1%) warm proton ring velocity distribution with a ring speed, v(r), varying between 2v(A) and 10v(A), where v(A) is the Alfven speed. Relatively cool background protons and electrons are assumed. The modeled ring velocity distributions are unstable to both the Alfven-cyclotron and ion Bernstein instabilities whose maximum growth rates are roughly a linear function of the ring speed. The mirror mode, which has real frequency omega(r)=0, becomes the fastest growing mode for sufficiently large v(r)/v(A). The mirror and Bernstein instabilities have maximum growth at propagation oblique to the background magnetic field and become more field-aligned with an increasing ring speed. Considering its largest growth rate, the mirror mode, in addition to the Alfven-cyclotron mode, can cause pitch angle diffusion of the ring protons when the ring speed becomes sufficiently large. Moreover, because the parallel phase speed, v(vertical bar ph), becomes sufficiently small relative to v(r), the low-frequency Bernstein waves can also aid the pitch angle scattering of the ring protons for large v(r). Potential implications of including these two instabilities at oblique propagation on heliospheric pickup ion dynamics are discussed.

Chiral Transition Metal Complexes under Resonance: Mechanism of a New Form of Chiral Raman Spectroscopy
Creators: Li, Guojie
Publisher: name: University of Alberta Library
Year: 2023

My PhD thesis primarily focuses on exploring chiroptical events and signatures of chiral transition metal complexes when they are under (near) resonance conditions. To achieve this goal, multiple chiroptical spectroscopic techniques were utilized, aided by theoretical calculations.  These chiroptical techniques include Raman optical activity (ROA), vibrational circular dichroism (VCD), electronic circular dichroism (ECD), and a new form of chiral Raman spectroscopy which was discovered during the thesis research. We named this new form ‘eCP-Raman’ which is a combination of ECD (abbreviated as ‘e’ in the name) and circularly polarized Raman (CP-Raman) spectroscopy. The thesis encompasses the long discovery journey of uncovering the mechanism responsible for the large, induced chiral Raman signatures of solvents when the associated chiral solute is under resonance. The development of the eCP-Raman mechanism leads to the realization that resonance ROA (RROA) spectra measured in the present thesis work and in previous reports by others are (severely) contaminated by eCP-Raman contributions.

More specifically, Chapter 3 describes the observation of the strong, induced chiral Raman response of achiral solvent molecules when a chiral transition metal complex solute is under resonance condition and the eventual discovery of the eCP-Raman mechanism responsible for it. In Chapter 4, we examined the chiral Raman responses of three different chiral solutes under resonance and concluded that eCP-Raman contributes dominantly in all three cases, whereas RROA contributes negligibly. Importantly, the observed chiral Raman signatures of the solutes were correctly simulated by the proposed eCP-Raman mechanism. Chapter 5 describes the chiroptical characterization of two new chiral transition metal complexes, which are (near) resonance with the laser wavelength of the ROA spectrometer used. In chapter 6, an approach to extract the true RROA spectrum of a chiral complex under resonance, based on the eCP-Raman mechanism, was proposed and applied. The comparison between the true RROA spectrum extracted and the preliminary simulation results, based on the latest theoretical RROA development, provides guidance for future development in this important direction.

description: We use the very high resolution, fully cosmological simulations from the Aquarius project, coupled to a semi-analytical model of galaxy formation, to study the phase-space distribution of halo stars in "solar neighbourhood"-like volumes. We find that this distribution is very rich in substructure in the form of stellar streams for all five stellar haloes we have analysed. These streams can be easily identified in velocity space, as well as in spaces of pseudo-conserved quantities such as E vs. Lz. In our best-resolved local volumes, the number of identified streams ranges from ~ 300 to 600, in very good agreement with previous analytical predictions, even in the presence of chaotic mixing. The fraction of particles linked to (massive) stellar streams in these volumes can be as large as 84%. The number of identified streams is found to decrease as a power-law with galactocentric radius. We show that the strongest limitation to the quantification of substructure in our poorest-resolved local volumes is particle resolution rather than strong diffusion due to chaotic mixing.

description: Private labels, also known as store brands, are an important component of competitive strategy among multi-product retailers, as they can increase retailers' power over suppliers in the vertical channel or facilitate horizontal differentiation among retailers. This paper seeks to identify the relative importance of each role, conditional on the location of both private labels and national brands of ice cream in attribute space. We find that retailers' share of the total margin (retail price less production cost) is higher for private labels than national brands when retailers choose to imitate national brands with their own offerings.

description: We study the stationary state of a population evolving under the action of random genetic drift, selection and recombination in which both deleterious and reverse beneficial mutations can occur. We find that the equilibrium fraction of deleterious mutations decreases as the population size is increased. We calculate exactly the steady state frequency in a nonrecombining population when population size is infinite and for a neutral finite population, and obtain bounds on the fraction of deleterious mutations. We also find that for small and very large populations, the number of deleterious mutations depends weakly on recombination, but for moderately large populations, recombination alleviates the effect of deleterious mutations. An analytical argument shows that recombination decreases disadvantageous mutations appreciably when beneficial mutations are rare as is the case in adapting microbial populations, whereas it has a moderate effect on codon bias where the mutation rates between the preferred and unpreferred codons are comparable.

description: The power gap around 0.5 Omega(e) (where Omega(e) is the equatorial electron gyrofrequency) of whistler-mode waves is commonly observed in the Earth's inner magnetosphere, but its generation mechanism is still under debate. By performing two-dimensional particle-in-cell simulations in a uniform background magnetic field, we investigate the spectral properties of whistler-mode waves excited by temperature anisotropic electrons. The waves have positive growth rates in a wide range of normal angles (theta approximate to 0 degrees-35 degrees), resulting in the generation of both parallel and nonparallel waves. Although the nonparallel wave modes are weaker than the parallel ones, they can cause the plateau-like shape around 0.5 V-Ae (where V-Ae represent the electron Alfven speed) in the parallel direction of electron velocity distribution. The plateau-like electron component can then lead to severe damping in the waves around 0.5 Omega(e )via the cyclotron resonance, and the power gap is formed. This mechanism is called as spectrum bite. Our study sheds fresh light on the well-known gap formation at similar to 0.5 Omega(e )in the whistler-mode waves, which is ubiquitously detected near the equator in the inner magnetosphere.

description: Using a three-dimensional global hybrid simulation, we investigate the formation and evolution of ion-scale magnetic reconnection inside an interplanetary rotational discontinuity (RD) owing to its interaction with the quasi-perpendicular (Q-perpendicular to) bow shock and the magnetosphere. The interplanetary magnetic field (IMF) is initially predominantly northward, while it changes to purely southward across the RD. A significantly thinned RD current layer with a width similar to ion skin depth and normal magnetic field B-n approximate to 0 is formed by a shock compression process as the RD interacts with the Q-perpendicular to shock. Magnetic reconnection thereupon takes place inside the thin RD current layer, where Hall magnetic and electric fields, reconnection electric field, and high-speed ion outflow jets are identified. Simultaneously, flux ropes form with an extension of a few ion inertial lengths. As the RD is transmitted into the magnetosheath, multiple reconnection sites lead to the formation of longer flux ropes. Moreover, magnetosheath reconnection is also found at new reconnection sites inside the RD. No reconnection is found in the Q-perpendicular to shock alone outside the RD. The flux ropes propagate poleward and tailward in the magnetosheath. In addition, magnetopause reconnection takes place under the southward IMF on the sunward side of the RD after the RD passes through the magnetopause.

description: In this work, we present a systematic study of the plasmon modes in a system of vertically stacked pair of graphene discs. Quasistatic approximation is used to model the eigenmodes of the system. Eigen-response theory is employed to explain the spatial dependence of the coupling between the plasmon modes and a quantum emitter. These results show a good match between the semi-analytical calculation and full-wave simulations. Secondly, we have shown that it is possible to engineer the decay rates of a quantum emitter placed inside and near this cavity, using Fermi level tuning, via gate voltages and variation of emitter location and polarization. We highlighted that by coupling to the bright plasmon mode, the radiative efficiency of the emitter can be enhanced compared to the single graphene disc case, whereas the dark plasmon mode suppresses the radiative efficiency.

description: The source of the non-thermal energy required for the heating of the upper solar atmosphere to temperatures in excess of a million degrees and the acceleration of the solar wind to hundreds of kilometres per second is still unclear. One such mechanism for providing the required energy flux is incompressible torsional Alfvén and kink magnetohydrodynamic (MHD) waves, which are magnetically dominated waves supported by the Sun's pervasive and complex magnetic field. In particular, propagating MHD kink waves have recently been observed to be ubiquitous throughout the solar atmosphere, but, until now, critical details of the transport of the kink wave energy throughout the Sun's atmosphere were unclear. Here, the ubiquity of the waves is exploited for statistical studies in the highly dynamic solar chromosphere. This large-scale investigation allows for the determination of the chromospheric kink wave velocity power spectra, a missing link necessary for determining the energy transport between the photosphere and corona. Crucially, the power spectra contains evidence for horizontal photospheric motions being the main mechanism for kink wave generation in the quiescent Sun. In addition, a comparison to measured coronal power spectra is provided, revealing frequency-dependent transmission profiles suggesting there is enhanced damping of kink waves in the lower corona.

However, in the presence of the 2-form fields and/or the radiation-like fluid in the string frame, the exact cosmological solutions show a minimum size of the universe in the evolution, but with an initial cosmological curvature singularity in the string frame.

It may be of considerable importance for destabilizing accretion disks, and plays a central role in the concept of the MRI dynamo. We report the results of a liquid metal Taylor-Couette experiment that shows the occurrence of an azimuthal MRI in the expected range of Hartmann numbers.

Its reconstruction is performed giving rise to an integration constant Q and other input parameters according to which we point out more analysis. Thereby, we show that for some values of this constant, the first and second laws of thermodynamics can be realized in the equilibrium description, for the universe with the temperature inside the horizon equal to that at the apparent horizon. Moreover, still within these suitable values of the constant, we show that the model may be stable using the de Sitter and Power-Law cosmological solutions.

description: BACKGROUND: Polygenic risk scores (PRS) have been widely applied in research studies, showing how population groups can be stratified into risk categories for many common conditions. As healthcare systems consider applying PRS to keep their populations healthy, little work has been carried out demonstrating their implementation at an individual level. CASE PRESENTATION: We performed a systematic curation of PRS sources from established data repositories, selecting 15 phenotypes, comprising an excess of 37 million SNPs related to cancer, cardiovascular, metabolic and autoimmune diseases. We tested selected phenotypes using whole genome sequencing data for a family of four related individuals. Individual risk scores were given percentile values based upon reference distributions among 1000 Genomes Iberians, Europeans, or all samples. Over 96 billion allele effects were calculated in order to obtain the PRS for each of the individuals analysed here. CONCLUSIONS: Our results highlight the need for further standardisation in the way PRS are developed and shared, the importance of individual risk assessment rather than the assumption of inherited averages, and the challenges currently posed when translating PRS into risk metrics.

description: AbstractAnte rem structures were posited as the subject matter of mathematics in order to resolve a problem of referential indeterminacy within mathematical discourse. Nevertheless, ante rem structuralists are inevitably committed to the existence of indiscernible entities, and this commitment produces an exactly analogous problem. If it cannot be sorted out, then the postulation of ante rem structures is futile. In a recent paper, Stewart Shapiro argued that the problem may be solved by analysing some of the singular terms of mathematics not as genuinely referring expressions, but as instantial terms. In this paper, I discuss several competing accounts of the semantics of terms of this kind, and argue that they are all untenable for the ante rem structuralist. Shapiro, then, still owes us an account of the semantics of instantial terms that suits the ante rem structuralist project. Without it, the ante rem structuralist is still unable to determine the reference of the singular terms of mathematics.

Alpaca homology

description: BACKGROUND: The history of comparative chromosome mapping is briefly reviewed, with discussion about the problem that occurs in chromosome painting when size heteromorphisms between homologues cause contamination in chromosomes sorted by flow cytometry that are used in the preparation of chromosome-specific DNA probes. MAIN BODY: As an example, we show in the alpaca (Vicagna pacos) that sequencing of contaminated chromosome sorts can reveal chromosome homologies from alignment with human and mouse genome reference sequences. The procedure identifies syntenic blocks of DNA separated in the human karyotype that are associated in the closely related alpaca and dromedary (Camelus dromedarius) karyotypes. This example provides proof of principal for the validity of the method for comparative chromosome mapping. CONCLUSION: It is suggested that the approach presented here may have application in the construction of comparative chromosome maps between distantly related taxa, such as monotremes and mammals.
Cluster algebras in scattering amplitudes with special 2D kinematics

description: We study the cluster algebra of the kinematic configuration space $Conf_n(\mathbb{P}^3)$ of a n-particle scattering amplitude restricted to the special 2D kinematics. We found that the n-points two loop MHV remainder function found in special 2D kinematics depend on a selection of \XX-coordinates that are part of a special structure of the cluster algebra related to snake triangulations of polygons. This structure forms a necklace of hypercubes beads in the corresponding Stasheff polytope. Furthermore in $n = 12$, the cluster algebra and the selection of \XX-coordinates in special 2D kinematics replicates the cluster algebra and the selection of \XX-coordinates of $n=6$ two loop MHV amplitude in 4D kinematics.

description: In many eukaryotic cells, directed molecular transport occurs along microtubules. Within neuronal axons, transport over vast distances particularly relies on uniformly oriented microtubules, whose plus-ends point towards the distal axon tip (anterogradely polymerizing, or plus-end-out). However, axonal microtubules initially have mixed orientations, and how they orient during development is not yet fully understood. Using live imaging of primary Drosophila melanogaster neurons, we found that, in the distal part of the axon, catastrophe rates of plus-end-out microtubules were significantly reduced compared to those of minus-end-out microtubules. Physical modelling revealed that plus-end-out microtubules should therefore exhibit persistent long-term growth, while growth of minus-end-out microtubules should be limited, leading to a bias in overall axonal microtubule orientation. Using chemical and physical perturbations of microtubule growth and genetic perturbations of the anti -catastrophe factor p150, which was enriched in the distal axon tip, we confirmed that the enhanced growth of plus-end-out microtubules is critical for achieving uniform microtubule orientation. Computer simulations of axon development integrating the enhanced plus-end-out microtubule growth identified here with previously suggested mechanisms, that is, dynein-based microtubule sliding and augmin-mediated templating, correctly predicted the long-term evolution of axonal microtubule orientation as found in our experiments. Our study thus leads to a holistic explanation of how axonal microtubules orient uniformly, a prerequisite for efficient long-range transport essential for neuronal functioning.

description: We prove that the double covers of the alternating and symmetric groups are determined by their complex group algebras. To be more precise, let $n\geq 5$ be an integer, $G$ a finite group, and let $\AAA$ and $\SSS^\pm$ denote the double covers of $\Al_n$ and $\Sy_n$, respectively. We prove that $\CC G\cong \CC \AAA$ if and only if $G\cong \AAA$, and $\CC G\cong \CC \SSS^+\cong\CC\SSS^-$ if and only if $G\cong \SSS^+$ or $\SSS^-$. This in particular completes the proof of a conjecture proposed by the second and fourth authors that every finite quasi-simple group is determined uniquely up to isomorphism by the structure of its complex group algebra. The known results on prime power degrees and relatively small degrees of irreducible (linear and projective) representations of the symmetric and alternating groups together with the classification of finite simple groups play an essential role in the proofs.

description: We study the dynamics of the entanglement spectrum, that is the time evolution of the eigenvalues of the reduced density matrices after a bipartition of a one-dimensional spin chain. Starting from the ground state of an initial Hamiltonian, the state of the system is evolved in time with a new Hamiltonian. We consider both instantaneous and quasi adiabatic quenches of the system Hamiltonian across a quantum phase transition. We analyse the Ising model that can be exactly solved and the XXZ for which we employ the time-dependent density matrix renormalisation group algorithm. Our results show once more a connection between the Schmidt gap, i.e. the difference of the two largest eigenvalues of the reduced density matrix and order parameters, in this case the spontaneous magnetisation.

Deadly Dads: Supports for Nêhiyaw Nâpêwak (Cree men) throughout fatherhood to  promote wellbeing—Impacts and understandings from a community-university  partnership
Creators: Purificati-Fune, Reuel AC

Mosoms and Kokoms (grandfathers and grandmothers) from the Cree communities of Maskwacis, Treaty 6 Territory identified an opportunity to welcome Nêhiyaw Nâpêwak (Cree men) back to ceremony. New interests within the field of maternal health, focusing on the Developmental Origins of Health and Disease and involving fathers align with existing understandings of wellbeing in Maskwacis. Through a long-standing community-university

partnership, we explored the impacts on wellbeing of a culturally-centered, community-led support strategy.

A community-based participatory research approach was shaped, honouring Nêhiyaw ways of knowing. A Community Advisory Committee including Mosoms, community members, and researchers led the research. Weekly group-led/developed support activities for men occurred from August 2021 to January 2023. This was a community-driven study through which our methods were iteratively determined. Two Wisdom Circles with participants were recorded, along with meeting minutes, journals, photos, implementation notes, community reports, and emails. Knowledge was analyzed non-linearly through relationships. Rigour was established through nurturing relationships, reflection and prayer, and offering tobacco to Mosoms for guidance and to participants sharing knowledge.

Strong relationships prompted re-understandings of the roles of researchers and strengthened kinship networks. Participants associated healthy gatherings, reassurance/motivation, intergenerational knowledge sharing, responsibility, shared positive memories, uplifted spirits, and connection to culture and identity with the group-led supports. Impacts occurred during what

was often referred to as ‘breaks’ from agendas, cycles of intergenerational trauma, the busyness of work, and fears of expressing love or healing.

Breaks from the coloniality of knowing and being create opportunities to connect with community, culture, ceremony, and identity, which is the source of wellbeing for Nêhiyaw Nâpêwak and families in Maskwacis.
