description: Experiments on crater formation in the strength regime were conducted using projectiles of various shapes with an aspect ratio of ~1, including both solid and hollow interiors. The surface diameter, inner (pit) diameter, and depth of the craters on basalt and porous gypsum targets were measured. Using the bulk density of the projectile, the surface diameter and depth for basalt and the pit diameter and depth for porous gypsum were scaled using the pi-scaling law for crater formation in the strength regime. The numerical code iSALE was used to simulate the impact of projectiles of various shapes and interior structure with similar bulk densities. Results show that the distributions of the maximum (peak) pressure experienced and particle velocity in the targets were similar regardless of projectile shape and interior structure, implying that the dimensions of the final craters were almost identical. This is consistent with the experimental results. Thus, we conclude that the size of the craters formed by the impact of projectiles with different shape and interior structure can be scaled using a conventional scaling law in the strength regime, using bulk density as projectile density.

The Barriers and Facilitators in Accessing Healthcare Services Among Foster Care Youth
Creators: name: Hernandez, Diana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: The number of children placed in foster care continues to remain high each year. In 2019, there were approximately 424,000 children in foster care. Youth in foster care have an increased risk of exposure to trauma, neglect, and violence compared to their counterparts not in foster care. While youth in foster care experience more health issues compared to their counterparts, there are several barriers to accessing adequate healthcare services. This can lead to additional health issues and negative behavioral consequences. While there is a high demand for healthcare services, many youth in foster care do not receive adequate treatment to meet their health needs. Social determinants of health play a key role in the barriers to healthcare access in this vulnerable population. A systematic review was conducted to examine systematically the literature related to barriers and facilitators in accessing healthcare services among youth in foster care. This review provides major findings from twenty-eight articles identifying nine overarching barriers and seven facilitators. Barriers and facilitators were identified across multiple levels including individual, family, healthcare system, and foster care system. These findings emphasize the crucial need for policy implications that include evidence-based practices and trauma-informed interventions to promote equitable healthcare access for this population. Ultimately, future studies should direct their efforts on analyzing the remaining barriers and facilitators and work to reduce health disparities and inequities in this already vulnerable population.

description: The damping effect of the free-streaming neutrinos on the second order gravitational waves is investigated in detail. We solve the Boltzmann equation and give the anisotropic stress induced by neutrinos to second order. The first order tensor and its coupling with scalar perturbations induced gravitational waves are considered. We give the analytic equations of the damping kernel functions and finally obtain the energy density spectrum. The results show that the free-streaming neutrinos suppress the density spectrum significantly for low frequency gravitational waves and enlarge the logarithmic slope $n$ in the infrared region ($k \ll k_*$) of the spectrum. For the spectrum of $k_*\sim 10^{-7}$Hz, the damping effect in the range of $k

description: Juniperus communis var. saxatilis is a short prostrate evergreen conifer that grows on dry hills in the mountain areas. In the Balkans, this taxon has a fragmented distribution. Both leaves and cones are rich in essential oils (EOs), which play an important role in plant interaction with the environment. Even though leaves and berries represent a significant source for humans and wildlife, there is no research on the genetic and EO variability in the region. In this article, we analysed individuals from 18 populations from the entire Balkan Peninsula. Three bioclimatic regions were identified, based on precipitation and temperatures. Amplified fragment length polymorphism (AFLP) data revealed high genetic variability, which is mostly located within the populations (91.7%). In total, 156 compounds representing 99.0% of total oil were detected and identified. Three chemotypes (ɑ-pinene, sabinene and δ-3-carene) were detected in all samples. Although all chemotypes could be detected throughout the region, their distribution was correlated with environmental factors. The influence of environmental variables on EO composition and chemophenetics are discussed.
Reflecting Voter Preferences in U.S. Presidential Primaries Using Ranked-Choice Election Systems
Creators: name: Kannan, Aarthi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: This paper assesses the effectiveness of various ranked-choice voting systems, as compared to the current plurality system, in reflecting aggregate voter preferences in United States presidential primary elections. Survey data, gathered in February 2020 by FairVote, elicited the ranked preferences of a random sample of likely Democratic primary voters for eight remaining candidates in the election at that point. I use these data to estimate a model of voter preferences and to simulate various election outcomes, including a simple plurality election and various types of ranked-choice elections. Voter preferences, which are analyzed using a multinomial logit choice model, inform the social welfare for the voting population that each candidate provides. Using these estimates of social welfare for each candidate, I assess how each ranked-choice election system compares to the current plurality system and which systems best reflect aggregate voter preferences. I also evaluate each system on the basis of various desirable criteria for practical application. I find that certain RCV mechanisms provide, in some instances, higher social utility for the voting population and that they meet desirable criteria better than does the simple plurality mechanism.

description: A type-I burst could influence the accretion process through radiation pressure and Comptonization both for the accretion disk and the corona/boundary layer of an X-ray binary, and vice versa. We investigate the temporal evolution of a bright photospheric radius expansion (PRE) burst of 4U 1608-52 detected by Insight-HXMT in 1-50 keV, with the aim of studying the interplay between the burst and persistent emission. Apart from the emission from the neutron star (NS) surface, we find the residuals both in the soft (<3 keV) and hard (>10 keV) X-ray band. Time-resolved spectroscopy reveals that the excess can be attributed to an enhanced pre-burst/persistent emission or the Comptonization of the burst emission by the corona/boundary layer. The Comptonization model is a convolution thermal-Comptonization model (thcomp in XSPEC) and the Comptonization parameters are fixed at the values derived from the persistent emission. We find, during the PRE phase, after the enhanced pre-burst/persistent emission or the Comptonization of the burst emission is removed, the NS surface emission shows a plateau, and then a rise until the photosphere touches down to the NS surface, resulting in a flux peak at that moment. We speculate that the findings above correspond to that the obscured lower part of the NS surface by the disk is exposed to the line of sight due to the inner disk evaporation by the burst emission. The consistency between the fa model and convolution thermal-Comptonization model indicates the interplay between thermonuclear bursts and accretion environments. These phenomena did not usually show up by the conventional blackbody model fitting, which may be due to low count rate and narrow energy coverage in previous observations.

description: This paper describes a currently being developed procedure of the charged particle identification for CMD-3 detector, installed at the VEPP-2000 collider. The procedure is based on the application of the boosted decision trees classification method, and uses as input variables, among others, the specific energy losses of charged particle in the layers of the liquid Xenon calorimeter. The efficiency of the procedure is demonstrated by an example of the extraction of events of e+e- to K+K- process in the center of mass energy range from 1.8 to 2.0 GeV.

title: Industrial Relations and Human
Resources Management: A Comparative
Analysis of Cultural Barriers in Chinese
Companies
Creators: name: Xi, Jing
Publisher: name: London South Bank University
Year: 2017

description: Given the impact of global commercialization, this research focuses on the
multinational corporations (MNCs) and their subsidiaries in the newly developing
transition economy in China, on the different forms of foreign direct investment (FDI) and
joint-venture companies (JVCs). The conceptual models on which this research is based
show that, in terms of industrial relations (IRs) and human resources management (HRM),
culture and languages, as invisible and forgotten factors, play important roles in
promoting or hindering managerial efficiency. The research objective is to determine
whether or not the linguistic and cultural barriers have a significant influence on the
MNCs in particular， IRs and HRM. As China transforms its economy, MNCs play a
strategic role and, in order to acquire international competitive advantages, search for
efficient IRs and HRM systems and practices.
The research has identified a conceptual model that allows a hypothesis to be
formed. The model has the advantage of combining cultural and linguistic factors, a
synthesis so far largely ignored by researchers. It is designed to explain the shape of
industrial relations institutions in the fields of bargaining, the amount of federal and
government involvement, the existence of works councils, the payment structure, etc. It
is suggested that, in the light of what has been learned from empirical studies (Warner,
1993; Greif, 1994; Globe, 1994; Child, 2003; Feely, 2003; Black, 2005), the research will
explore how cultural factors in different stratifications have had an impact on FDI and
JVCs industrial relations and HRM strategies in China. The empirical work mentioned has
demonstrated a deficit of research focusing on culture and language so this research will
make a valuable contribution to the field.
To answer what role culture/language play and how and why, both quantitative and
qualitative research methods are deemed suitable. Two typical MNCs, one located in
Shanghai, the Yangtze Delta Zone and the other in Canton, the Pearl River Delta Zone, are
planned to be used as subjects of case studies. The research also includes a survey by using questionnaires focusing on the mass FDIs and JVCs in east and south China.
We therefore have two goals: first, to build up theories of culture and language
functions in international management and present evidence scientifically for further
research; second, to provide references for practitioners dealing in international business,
especially those who work as expatriates in transition economies. This research is
expected to contribute to both theory and practice in IRs and HRM management for
Anglo-Saxon culture based MNCs in China.

description: Electron spin qubits in silicon, whether in quantum dots or in donor atoms, have long been considered attractive qubits for the implementation of a quantum computer due to the semiconductor vacuum character of silicon and its compatibility with the microelectronics industry. While donor electron spins in silicon provide extremely long coherence times and access to the nuclear spin via the hyperfine interaction, quantum dots have the complementary advantages of fast electrical operations, tunability and scalability. Here we present an approach to a novel hybrid double quantum dot by coupling a donor to a lithographically patterned artificial atom. Using gate-based rf reflectometry, we probe the charge stability of this double quantum dot system and the variation of quantum capacitance at the interdot charge transition. Using microwave spectroscopy, we find a tunnel coupling of 2.7 GHz and characterise the charge dynamics, which reveals a charge T2* of 200 ps and a relaxation time T1 of 100 ns. Additionally, we demonstrate spin blockade at the inderdot transition, opening up the possibility to operate this coupled system as a singlet-triplet qubit or to transfer a coherent spin state between the quantum dot and the donor electron and nucleus.

description: A region 140 square degrees toward the Galactic Centre was searched for monochromatic optical light, both pulses shorter than 1 sec and continuous emission. A novel instrument was constructed that acquires optical spectra of every point within 6 square degrees every second, able to distinguish lasers from astrophysical sources. The system consists of a modified Schmidt telescope, a wedge prism over the 0.28-meter aperture, and a fast CMOS camera with 9500 x 6300 pixels. During 2021, a total of 34800 exposures were obtained and analyzed for monochromatic sources, both sub-second pulses and continuous in time. No monochromatic light was found. A benchmark laser with a 10-meter aperture and located 100 light years away would be detected if it had a power more than ~60 megawatt during 1 sec, and from 1000 light years away, 6000 MW is required. This non-detection of optical lasers adds to previous optical SETI non-detections from more than 5000 nearby stars of all masses, from the Solar gravitational lens focal points of Alpha Centauri, and from all-sky searches for broadband optical pulses. These non-detections, along with those of broadband pulses, constitute a growing SETI desert in the optical domain.

description: We present MadDM v.2.0, a numerical tool for dark matter physics in a generic model. This version is the next step towards the development of a fully automated framework for dark matter searches at the interface of collider physics, astro-physics and cosmology. It extends the capabilities of v.1.0 to perform calculations relevant to the direct detection of dark matter. These include calculations of spin-independent/spin-dependent nucleon scattering cross sections and nuclear recoil rates (as a function of both energy and angle), as well as a simplified functionality to compare the model points with existing constraints. The functionality of MadDM v.2.0 incorporates a large selection of dark matter detector materials and sizes, and simulates detector effects on the nuclear recoil signals. We validate the code in a wide range of dark matter models by comparing results from MadDM v.2.0 to the existing tools and literature.

description: Plant translocations have been performed and are ongoing, aimed at establishing long-term resilient and self-sustaining populations. Nevertheless, some of them have not succeeded because of failure in pre- and post-translocation phases such as erroneous site selection and lack of long-term monitoring and adaptive management (i.e. aftercare). This study focused on the relative importance of site suitability and aftercare on the performance of reintroduced populations of Kosteletzkya pentacarpos. This species was studied in two sites representing opposite ends of its ecological niche (freshwater and brackish sites), in the presence of the local vegetation (Phragmites australis and Juncus sp. pl.) and in its absence. Data on environmental variables, plant growth, ecophysiology and reproductive performance were obtained. Kosteletzkya pentacarpos performed better in the brackish site, exhibiting higher performance especially in the presence of the local vegetation. Conversely, plants growing in the freshwater site had lower performance, despite the removal of the local vegetation. Environmental features of the sites affected species performance more than interactions with co-existing species and site management, highlighting that selection of suitable recipient site is crucial to ensure successful translocation. Aftercare is unlikely to effectively counteract the effect of sub-optimal ecological conditions in terms of plant establishment and performance.
Non-trivial class of anisotropic compact stellar model in Rastall gravity

description: We investigated Rastall gravity, for an anisotropic star with a static spherical symmetry, whereas the matter-geometry coupling as assumed in Rastall Theory (RT) is expected to play a crucial role in differentiating RT from General Relativity (GR). Indeed, all the obtained results confirm that RT is not equivalent to GR, however, it produces the same amount of anisotropy as GR for static spherically symmetric stellar models. We used the observational constraints on the mass and the radius of the pulsar \textit{Her X-1} to determine the model parameters confirming the physical viability of the model. We found that the matter-geometry coupling in RT allows slightly less size than GR for a given mass. We confirmed the model viability via other twenty pulsars' observations. Utilizing the strong energy condition we determined an upper bound on compactness $U_\text{max}\sim 0.603$, in agreement with the Buchdahl limit, whereas Rastall parameter $ε=-0.1$. For a surface density compatible with a neutron core at nuclear saturation density, the mass-radius curve allows masses up to $3.53 M_\odot$. We note that there is no equation of state is assumed, however, the model fits well with a linear behavior. We split the twenty pulsars into four groups according to the boundary densities. Three groups are compatible with neutron cores while one group fits perfectly with higher boundary density $8\times 10^{14}$ g/cm$^3$ which suggests that those pulsars may have quark-gluon cores.

Boys Who Cry Wolf: Introducing the FEM-V Phenomenon, a Conceptual Framework for Active Ideological Shooters
Creators: name: Doty, Mary Bennett
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: This study provides an examination of the active ideological shooter phenomenon in North America from December 1975 to March 2021 through a gendered lens. Extent literature surrounding violent extremist ideologies and active ideological shooters have yet to incorporate a stand-alone phenomenon regarding gender-based mass shootings. Thus, this study introduces Female-Centric Extremist Motivated Violence (FEM-V) as the overarching phenomenon for men motivated by grievances against women to commit acts of violence in the hopes of achieving personal glory. Case studies of renowned serial killer David Berkowitz, Montreal shooter Marc Lépine, incel shooter Elliot Rodger, and recently arrested Rodger enthusiast David Kaufman are used to examine FEM-V manifestations across a variety of labels currently used for acts of violence against women within the field of security studies. Furthermore, this study reconceptualizes the foundational criteria used for “terrorism," by adapting it to include personal glory as a foundational piece of the collective FEM-V ideology.

description: In this paper, an alternative method to range-separated linear-response time-dependent density-functional theory and perturbation theory is proposed to improve the estimation of the energies of a physical system from the energies of a partially interacting system. Starting from the analysis of the Taylor expansion of the energies of the partially interacting system around the physical system, we use an extrapolation scheme to improve the estimation of the energies of the physical system at an intermediate point of the range-separated or linear adiabatic connection where either the electron--electron interaction is scaled or only the long-range part of the Coulomb interaction is included. The extrapolation scheme is first applied to the range-separated energies of the helium and beryllium atoms and of the hydrogen molecule at its equilibrium and stretched geometries. It improves significantly the convergence rate of the energies toward their exact limit with respect to the range-separation parameter. The range-separated extrapolation scheme is compared with a similar approach for the linear adiabatic connection, highlighting the relative strengths and weaknesses of each approach.

description: Because of the diversity of stellar masses and orbital sizes of binary systems, and the complex interaction between star-star, star-planet and planet-planet, it has been difficult to fully characterize the planetary systems associated with binary systems. Here, we report high-precision astrometric observations of the low-mass binary system GJ 896AB, revealing the presence of a Jupiter-like planetary companion (GJ 896Ab). The planetary companion is associated to the main star GJ 896A, with an estimated mass of 2.3 Jupiter masses and an orbit period of 284.4 days. A simultaneous analysis of the relative astrometric data obtained in the optical and infrared with several telescopes, and the absolute astrometric data obtained at radio wavelengths with the Very Long Baseline Array (VLBA), reveals, for the first time, the fully characterized three-dimensional (3D) orbital plane orientation of the binary system and the planetary companion. The planetary and binary orbits are found to be in a retrograde configuration and with a large mutual inclination angle ($Φ$ = 148 deg) between both orbital planes. Characterizing the 3D orbital architecture of binary systems with planets is important in the context of planet formation, as it could reveal whether the systems were formed by disk fragmentation or turbulence fragmentation, as well as the origin of spin-orbit misalignment. Furthermore, since most stars are in binary or multiple systems, our understanding of systems such as this one will help to further understand the phenomenon of planetary formation in general.

description: Cilia and flagella are ideal model organelles in which to study the general question of organelle size control. Flagellar microtubules are steady-state structures whose size is set by the balance of assembly and disassembly. Assembly requires intraflagellar transport (IFT), and measurements of IFT have shown that the rate of entry of IFT particles into the flagellum is a decreasing function of length. It has been proposed that this length dependence of IFT may be the basis for flagellar length control. Here, we test this idea by showing that three different long-flagella mutations in Chlamydomonas all cause increased IFT injection, thus confirming that IFT can influence length control. However, quantitative comparisons with mathematical models suggest that the increase in injection is not sufficient to explain the full increase in length seen in these mutants; hence, some other mechanism may be at work. One alternative mechanism that has been proposed is length-regulated binding of tubulin to the IFT particles. However, we find that the apparent length dependence of tubulin loading that has previously been reported may actually reflect length-dependent organization of IFT trains.This article is part of the Theo Murphy meeting ‘Unity and diversity of ciliary systems in locomotion and transport’.
Brownian motion theory of the two-dimensional quantum vortex gas
Creators: name: Kuratsuji, Hiroshi
Publisher: name: arXiv
Year: 2022
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: A theory of Brownian motion is presented for an assembly of vortices. The attempt is motivated by a realization of Dyson' Coulomb gas in the context of quantum condensates. By starting with the time-dependent Landau-Ginzburg (LG) theory, the dynamics of the vortex gas is constructed, which is governed by the canonical equation of motion. The dynamics of point vortices is converted to the Langevin equation, which results in the generalized Fokker-Planck (GFP) (or Smolkovski) equation using the functional integral on the ansatz of the Gaussian white noise. The GFP, which possesses a non-Hermitian property, is characterized by two regimes called the "overdamping" and the "underdamping" regime. In the overdamping regime, where the dissipation is much larger than the vortex strength, the GFP becomes the standard Fokker-Planck equation, which is transformed to the two-dimensional many particle system. Several specific applications are given of the Fokker-Planck equation. An asymptotic limit of small diffusion is also discussed for the two vortices system. The underdamping limit, for which the vortex charge is much larger than the dissipation, is briefly discussed.

description: In this work we study opinion formation in a population participating of a public debate with two distinct choices. We considered three distinct mechanisms of social interactions and individuals' behavior: conformity, nonconformity and inflexibility. The conformity is ruled by the majority-rule dynamics, whereas the nonconformity is introduced in the population as an independent behavior, implying the failure to attempted group influence. Finally, the inflexible agents are introduced in the population with a given density. These individuals present a singular behavior, in a way that their stubbornness makes them reluctant to change their opinions. We consider these effects separately and all together, with the aim to analyze the critical behavior of the system. We performed numerical simulations in some lattice structures and for distinct population sizes, and our results suggest that the different formulations of the model undergo order-disorder phase transitions in the same universality class of the Ising model. Some of our results are complemented by analytical calculations.

description: Hybridization is a process of great importance in the ecology and evolution of plants. However, identifying hybrids is not an easy task, especially in cases of sympatry. Such cases are the Abies taxa in Greece; Silver fir (A. alba), Greek fir (A. cephalonica) and King Boris fir (A. × borisii-regis). The latter has been characterized as a hybrid between the first two species as its morphological traits are either a combination of the parental ones or intermediate. Besides the morphological traits, A. × borisii-regis has so far been identified only at the population level, with biochemical and DNA markers. Here, we describe the identification of A. × borisii-regis at the individual level by employing a species-specific marker in the cpDNA and another in mtDNA, taking advantage of their uniparental inheritance mode from the paternal and the maternal parent, respectively. In addition, based on these markers, essential information emerges on the distribution and the mtDNA diversity of the Abies taxa in Greece.

description: Cilia and flagella are ideal model organelles in which to study the general question of organelle size control. Flagellar microtubules are steady-state structures whose size is set by the balance of assembly and disassembly. Assembly requires intraflagellar transport (IFT), and measurements of IFT have shown that the rate of entry of IFT particles into the flagellum is a decreasing function of length. It has been proposed that this length dependence of IFT may be the basis for flagellar length control. Here, we test this idea by showing that three different long-flagella mutations in Chlamydomonas all cause increased IFT injection, thus confirming that IFT can influence length control. However, quantitative comparisons with mathematical models suggest that the increase in injection is not sufficient to explain the full increase in length seen in these mutants; hence, some other mechanism may be at work. One alternative mechanism that has been proposed is length-regulated binding of tubulin to the IFT particles. However, we find that the apparent length dependence of tubulin loading that has previously been reported may actually reflect length-dependent organization of IFT trains.This article is part of the Theo Murphy meeting ‘Unity and diversity of ciliary systems in locomotion and transport’.
ALMA Census of Faint 1.2 mm Sources Down to ~0.02 mJy: Extragalactic Background Light and Dust-Poor High-z Galaxies

description: We present statistics of 133 faint 1.2-mm continuum sources detected in about 120 deep ALMA pointing data that include all the archival deep data available by 2015 June. We derive number counts of 1.2 mm continuum sources down to 0.02 mJy partly with the assistance of gravitational lensing, and find that the total integrated 1.2 mm flux of the securely identified sources is 22.9^(+6.7)_(-5.6) Jy deg^(-2) that corresponds to 104^(+31)_(-25) % of the extragalactic background light (EBL) measured by COBE observations. These results suggest that the major 1.2 mm EBL contributors are sources with 0.02 mJy, and that very faint 1.2 mm sources with ~< 0.02 mJy contribute negligibly to the EBL with the possible flattening and/or truncation of number counts in this very faint flux regime. To understand the physical origin of our faint ALMA sources, we measure the galaxy bias bg by the counts-in-cells technique, and place a stringent upper limit of bg < 3.5 that is not similar to bg values of massive DRGs and SMGs but comparable to those of UV-bright sBzKs and LBGs. Moreover, in optical and near-infrared (NIR) deep fields, we identify optical-NIR counterparts for 59% of our faint ALMA sources, majority of which have luminosities, colors, and the IRX-beta relation same as sBzKs and LBGs. We thus conclude that about a half of our faint ALMA sources are dust-poor high-z galaxies as known as sBzKs and LBGs in optical studies, and that these faint ALMA sources are not miniature (U)LIRGs simply scaled down with the infrared brightness.

Ecological Role of a Cosmopolitan Testate Rhizopod, Paulinella ovalis, in the Microbial Food Web of a Eutrophic Estuary
Creators: name: Townsend, Luke
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Paulinella ovalis is a heterotrophic nanoplanktonic rhizopod abundant in estuarine and coastal waters. In the microbial food web, heterotrophic nanoplankton (HNP) consume picophytoplankton and are grazed by larger heterotrophs–recycling organic matter and transferring carbon to higher trophic levels. This generalization of HNP’s food web role is based primarily on studies of heterotrophic nanoflagellates (HNF). Little is known about the function of P. ovalis, but this study hypothesizes a similar role to HNF based on analogous size (four-microns) and trophic mode. This study assesses the hypothesis by examining the spatial and seasonal distribution of P. ovalis and its picocyanobacterial prey in the Neuse River Estuary (NRE), by measuring its growth rates, and estimating its potential grazing pressure on picocyanobacteria. P. ovalis abundance paralleled that of picocyanobacteria with higher abundance in warmer, saltier waters. P. ovalis growth rates ranged from -0.11, 0.25, and 0.43 per day–establishing a minimum growth rate of at least 0.3 d-1. Based on a 0.3 d-1 growth rate and assuming a biomass yield of 0.3 from literature values, P. ovalis has the potential to consume ~48% of the picocyanobacteria population per day. Since ~50% of primary production in the NRE is produced by picocyanobacteria, it is possible that 25% of primary production is consumed by P. ovalis. These estimates demonstrate the potential importance of P. ovalis within the microbial food web, and should motivate future studies to directly measure the grazing rates by and on P. ovalis to further assess its role in the food web.

description: This paper considers the multiple-access relay channel in a setting where two source nodes transmit packets to a destination node, both directly and via a relay node, over packet erasure channels. Intra-session network coding is used at the source nodes and inter-session network coding is employed at the relay node to combine the recovered source packets of both source nodes. In this work, we investigate the performance of the network-coded system in terms of the probability that the destination node will successfully recover the source packets of the two source nodes. We build our analysis on fundamental probability expressions for random matrices over finite fields and we derive upper bounds on the system performance for the case of systematic and non-systematic network coding. Simulation results show that the upper bounds are very tight and accurately predict the decoding probability at the destination node. Our analysis also exposes the clear benefits of systematic network coding at the source nodes compared to non-systematic transmission.

Prolongations of t-Motives and Algebraic Independence of Periods
Creators: name: Maurischat
Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2018

description: In this article we show that the coordinates of a period lattice generator of the n-th tensor power of the Carlitz module are algebraically independent, if n is prime to the characteristic. The main part of the paper, however, is devoted to a general construction for t-motives which we call prolongation, and which gives the necessary background for our proof of the algebraic independence. Another incredient is a theorem which shows hypertranscendence for the Anderson-Thakur function ω(t), i.e. that ω(t) and all its hyperderivatives with respect to t are algebraically independent.

The $pλn$ fractal decomposition: Nontrivial partitions of conserved physical quantities

description: A mathematical method for constructing fractal curves and surfaces, termed the $pλn$ fractal decomposition, is presented. It allows any function to be split into a finite set of fractal discontinuous functions whose sum is equal everywhere to the original function. Thus, the method is specially suited for constructing families of fractal objects arising from a conserved physical quantity, the decomposition yielding an exact partition of the quantity in question. Most prominent classes of examples are provided by Hamiltonians and partition functions of statistical ensembles: By using this method, any such function can be decomposed in the ordinary sum of a specified number of terms (generally fractal functions), the decomposition being both exact and valid everywhere on the domain of the function.
