description: The successful prediction of light element abundances from Big Bang Nucleosynthesis has been a pillar of the standard model of Cosmology. Because many of the relevant reaction rates are sensitive to the values of fundamental constants, such as the fine structure constant and the strong coupling constant, BBN is a useful tool to probe and to put constraints on possible cosmological variations of these constants, which arise naturally from many versions of extra-dimensional theories. In this paper, we study the dependences of fundamental constants on the radion field of the universal extra dimension model, and calculate the effects of such varying constants on BBN. We show that the discrepancy between BBN and the Wilkinson Microwave Anisotropy Probe data on the baryon-to-photon ratio may be reduced if the volume of the extra dimensions was slightly larger - by $\mathcal{O} (10^{-3})$ - at the BBN era compared to its present value, which would result in smaller gauge couplings at BBN by the same factor.

description: We investigate mucosalivary dispersal and deposition on horizontal surfaces corresponding to human exhalations with physical experiments under still-air conditions. Synthetic fluorescence tagged sprays with size and speed distributions comparable to human sneezes are observed with high-speed imaging. We show that while some larger droplets follow parabolic trajectories, smaller droplets stay aloft for several seconds and settle slowly with speeds consistent with a buoyant cloud dynamics model. The net deposition distribution is observed to become correspondingly broader as the source height $H$ is increased, ranging from sitting at a table to standing upright. We find that the deposited mucosaliva decays exponentially in front of the source, after peaking at distance $x = 0.71$\,m when $H = 0.5$\,m, and $x = 0.56$\,m when $H=1.5$\,m, with standard deviations $\approx 0.5$\,m. Greater than 99\% of the mucosaliva is deposited within $x = 2$\,m, with faster landing times {\em further} from the source. We then demonstrate that a standard nose and mouth mask reduces the mucosaliva dispersed by a factor of at least a hundred compared to the peaks recorded when unmasked.

description: Driven by use case scenarios, WP5 aims to evaluate the results obtained in WP2 (Policy and Transparency Framework), WP3 (Big Data Policy Engine), and WP4 (User Interaction) under real world conditions. More specifically, the goal of T5.3 Public challenges is to expose the developed system and its components to public hacking challenges, which would, together with the internal backend scalability and robustness testing performed in WP3 (D3.3 and D3.5) and frontend testing in WP4 (D4.2 and D4.4), provide the necessary feedback for further development of the SPECIAL platform. In D5.2 Public Challenge Report V1, we explained that in order to guarantee the robustness of our architecture, such challenges must focus on ensuring that both the individual components and the infrastructure as a whole are capable of sharing data only with authorized parties, while guaranteeing that policies and regulations are being adhered to. We also argued that this means involving other aspects of the system, be it technical or legal, highlighting any limitations. This is worth repeating as the outcome of the three rounds of challenges has made us reconsider and adapt our strategy, as we will explain further below.

Finite Volume Dependence of Hadron Properties and Lattice QCD

description: Because the time needed for a simulation in lattice QCD varies at a rate exceeding the fourth power of the lattice size, it is important to understand how small one can make a lattice without altering the physics beyond recognition. It is common to use a rule of thumb that the pion mass times the lattice size should be greater than (ideally much greater than) four (i.e., $m_πL \gg 4$). By considering a relatively simple chiral quark model we are led to suggest that a more realistic constraint would be $m_π(L - 2R) \gg 4$, where $R$ is the radius of the confinement region, which for these purposes could be taken to be around 0.8-1.0 fm. Within the model we demonstrate that violating the second condition can lead to unphysical behaviour of hadronic properties as a function of pion mass. In particular, the axial charge of the nucleon is found to decrease quite rapidly as the chiral limit is approached.

description: This paper revives the controversial debate that has arisen over the last two decades about the possibility that the electromagnetic field affects the lifetime or the decay rate of an unstable particle. In this research, we show, by performing analytical calculations and extracting numerical results, that the pion lifetime can be changed notably by inserting the decaying pion into an electromagnetic field only if the number of photons transferred between the decaying system and the laser field does not reach the well-known sum-rule. The influence of the laser parameters on the decay rate and branching ratio is also discussed. The surprising result obtained for the pion lifetime is referred to as the well-known quantum Zeno effect.

description: We examine an effect of acoustic phonon scattering on an electric conductivity of single-component molecular conductor [Pd(dddt)$_2$] (dddt = 5,6-dihydro-1,4-dithiin-2,3-dithiolate) with a half-filled band by applying the previous calculation in a two-dimensional model with Dirac cone [Phys. Rev. B {\bf 98},161205 (2018)], where the electric transport by the impurity scattering exhibits the noticeable interplay of the Dirac cone and the phonon scattering,resulting in a maximum of the conductivity with increasing temperature. The conductor shows a nodal line semimetal where the band crossing of HOMO (Highest Occupied Molecular Orbital) and LUMO (Lowest Unoccupied Molecular Orbital) provides a loop of Dirac points located close to the Fermi energy followed by the density of states (DOS) similar to that of two-dimensional Dirac cone. Using a tight-binding (TB) model [arXiv:2008.09277], which was obtained using the crystal structure observed from a recent X ray diffraction experiment under pressure, it is shown that the obtained conductivity explains reasonably the anomalous behavior in [Pd(dddt)$_2$] exhibiting almost temperature independent resistivity at finite temperatures. This paper demonstrates a crucial role of the acoustic phonon scattering at finite temperatures in the electric conductivity of Dirac electrons. The present theoretical results of conductivity are compared with those of experiments.

description: This article presents a study that compares detected structural communities in a coauthorship network to the socioacademic characteristics of the scholars that compose the network. The coauthorship network was created from the bibliographic record of a multi-institution, interdisciplinary research group focused on the study of sensor networks and wireless communication. Four different community detection algorithms were employed to assign a structural community to each scholar in the network: leading eigenvector, walktrap, edge betweenness and spinglass. Socioacademic characteristics were gathered from the scholars and include such information as their academic department, academic affiliation, country of origin, and academic position. A Pearson's $χ^2$ test, with a simulated Monte Carlo, revealed that structural communities best represent groupings of individuals working in the same academic department and at the same institution. A generalization of this result suggests that, even in interdisciplinary, multi-institutional research groups, coauthorship is primarily driven by departmental and institutional affiliation.

description: Characters of A. officinalis suitable for diagnostic purposes: comparison with A. mayeti
(Figures 7 (A–G), 8(A–D), 9(A–D))
Armadillo officinalis is easily recognised by its dark grey-brown colour with yellow typical muscle spots, antenna, pleon, pleotelson, pereopods and uropods strongly pigmented (Figure 7 (A)), bigger size (male 12.5 mm; female 10.5 mm), smooth integument and more numerous (14) ommatidia (Figure 7 (C)); tergite pereonite I showing denser and smaller scale-setae (Figure 7 (C)) with two divergent lobes (Figure 7 (D)). It differs also from A. mayeti in having narrower antenna, with the fifth article 1.5-times as long as the flagellum (Figure 8 (A)), pereonite I with lateral groove deeper in anterior part, inner lobe not surpassing posterior margin of outer lobe (Figure 7 (B)), caudal lamellar process with rounded apex (Figure 7 (E)), telson nearly twice as wide as long, basal two-times longer than distal part (Figure 9 (A)), stridulation apparatus on propodus of pereopods 4 and 5 forming row of juxtaposed globular scales (Figure 7 (F, G)) having a less diverse chemical composition and richer in Ca (54.75%), followed by carbon rate (30.82%) and oxygen (Table 1). Pereopds 1 and 7 (Figure 8 (B, C)) are similar to those of A. mayeti, but the carpus 1 and 7 are nearly twice as long as the merus. Male pleopods 1 and 2 (Figure 9 (C, D)) of both species are quite similar.
Regarding the uropod, the protopod, nearly as long as wide, has a shorter distal part (Figure 8 (D)); the exopodite insertion is slightly posterior to the narrowest part of the telson (Figure 9 (B)) in A. officinalis.

Sharing the range: the challenges and opportunities for sustainable ranching and habitat conservation in the municipal district of Pincher Creek
Creators: name: Sadilkova, Regina Maria
Publisher: name: University of British Columbia
Year: 2009

description: The broad scope and intent of this thesis is to contribute to the body of research and writing about the loss of agricultural land due to development and the transformation of rural agricultural communities. At the more specific level, through interviews and secondary research, this thesis considers municipal land use planning in Alberta under the revised 1995 Municipal Government Act in the Municipal District (MD) of Pincher Creek No. 9, where cattle ranching, wildlife, and now, acreages vie for land resources. The critical questions addressed are: What are the conflicts between ranching and habitat conservation, and conversely, what opportunities do they share? What role can and does a municipality play in promoting sustainable ranching and conservation through its land use policy and jurisdiction? Set in southwest corner of Alberta, the MD of Pincher Creek is endowed with a remarkable history of ranching, ample resource wealth, and a unique climate and topography that supports a spectacular, rich, diverse ecosystem. Within the past few years, private agricultural land near Waterton Lakes National Park and the Castle River wilderness in the MD has come under speculative and development pressure predominantly for country residences, often retirement homes, and for tourism interests. Recent Municipal Act amendments have delegated substantially more land use control to rural municipalities, as a result the MD of Pincher Creek has more authority to make decisions that shape its future community profile, to mediate between competing land use interests, and to impact local ranching and habitat. The thesis analysis explores how the best practices of ranching or "sustainable ranching" can help to conserve and enhance habitat and how ranchers' attitudes can evolve to be more tolerant of wildlife. This thesis also explores and supports the efforts of a budding local land trust, SALTS, which plans to protect local agricultural land and habitat through conservation easements. Finally, the thesis concludes by envisioning ways the MD government can encourage habitat preservation, conservation easements, sustainable and economically viable ranching, as well as the control and direction of country residential development, all with a view to ensuring that future economic development opportunities remain available for local residents.

Repair Schwann cells: bridging the gap for successful nerve repair in the PNS
Creators: name: Gilmore, Evan
Publisher: name: No Publisher Supplied
Year: 2021

description: Peripheral nerve injuries remain a very prominent issue in today’s society all over the world, and can be sustained while working with machinery, playing sports or simply driving. Our current knowledge of the topic has limited applications for medical professionals in regards to treatments and surgeries they can perform to allow a patient to regain function in the nerve, which clearly leaves room for drastic improvement. Some organisms like mice and other murine species have demonstrated an ability to enact a Schwann cell facilitated nerve repair program that not all other organisms demonstrate when inflicted with a peripheral nerve injury particularly a severed nerve. As it stands our current comprehension of how organisms like these respond to peripheral nerve injuries on a cellular/molecular level is not complete and is still developing, but by studying these organisms over several decades we have made significant progress in the endeavor regardless. This review will discuss the known differences in nerve repair programs in human and mice, the most studied molecules and their molecular pathways that initiate the nerve repair program based on some of the most recently published literature on the topic and what we can take away from nerve injury models to develop future treatments and surgeries.

It turns out that formal analogues of classical transformation kernels and the resolvent identity can be used to understand the situation. In the lack of $\frac12$, the functions $\frac12-\frac12\sgn(\frac12-z)$ and $\frac12-\sqrt{\frac14-z}$ can be generalized, respectively.

Loricariidae.
Japurá Suckermouth; Pez Diablo, Plecostomo, Pleco, Arrisuaca, Chupapiedras, Pez Gato Acorazado (Fig. 2G).
Diagnosis: This exotic species differs from other congeners as well as related species of the Hypostominae (Loricariidae) occurring in Middle American freshwaters by the following combination of characters: jaws long, with dentaries approaching a 180° angle; teeth villiform and numerous (>60); hypertrophied odontodes on evertible plates on the cheek absents; dorsal fin elements II, 7; and coloration pattern (greyish blue to greyish brown with several black spots on the body, fins and abdomen). See Matamoros et al. (2016) for a detailed comparative analysis.
Basis of the record: Several captures have been recently (2013–2021) reported by artisanal and sport anglers in the lower and middle portions (0– 110 m.a.s.l.) of the Lago de Nicaragua, Río Frío, San Juan, San Carlos, Sarapiquí, Tortuguero, Parismina (Atlantic), Nicoya, Tempisque, Bebedero and Barranca (Pacific) River basins.
Remarks: This species was recorded around the Lago de Nicaragua, at the Rivas Department (municipality of Cardenas), by Matamoros et al. (2016). Published and unpublished records of Hypostomus aspidolepis (Günther, 1867) in Costa Rican freshwaters outside its native range of distribution (i.e., the Térraba and Coto River basins), e.g., Herrera & Molina (2011), also could correspond to this invasive species. The “ cf. ” designation was employed, following Matamoros et al. (2016), since H. niceforoi may be a species complex that probably will be divided into multiple species in the future.

description: Be stars are a class of rapidly rotating B stars with circumstellar disks that cause Balmer and other line emission. There are three possible reasons for the rapid rotation of Be stars: they may have been born as rapid rotators, spun up by binary mass transfer, or spun up during the main-sequence (MS) evolution of B stars. To test the various formation scenarios, we have conducted a photometric survey of 55 open clusters in the southern sky. Of these, five clusters are probably not physically associated groups and our results for two other clusters are not reliable, but we identify 52 definite Be stars and an additional 129 Be candidates in the remaining clusters. We use our results to examine the age and evolutionary dependence of the Be phenomenon. We find an overall increase in the fraction of Be stars with age until 100 Myr, and Be stars are most common among the brightest, most massive B-type stars above the zero-age MS (ZAMS). We show that a spin-up phase at the terminal-age MS (TAMS) cannot produce the observed distribution of Be stars, but up to 73% of the Be stars detected may have been spun-up by binary mass transfer. Most of the remaining Be stars were likely rapid rotators at birth. Previous studies have suggested that low metallicity and high cluster density may also favor Be star formation. Our results indicate a possible increase in the fraction of Be stars with increasing cluster distance from the Galactic center (in environments of decreasing metallicity). However, the trend is not significant and could be ruled out due to the intrinsic scatter in our data. We also find no relationship between the fraction of Be stars and cluster density.

description: Recently, layered hybrid perovskites have been attracting huge interest due to a wide range of possible chemical compositions and the resulting tunability of the materials properties. In this study, we investigate the effect of the chain length of the organic ligands on the optical properties of stacks of two dimensional perovskite layers consisting of alkylammonium lead iodide (CnH2n+1NH3)2PbI4 with n=4-18. Photoluminescence and absorption spectroscopy reveal a blueshift with increasing chain length n including a jump of 110 meV between the n=10 and n=12 ligands due to a change in octahedral tilting. Using Xray diffraction (XRD) we determine the crystal structure and find the octahedral tilting to be the main cause of this blueshift. However, for very short chain lengths additional effects further reduce the transition energy. Results of effective mass approximation model calculations show good agreement between the expected reduction of transition energy and measured photoluminescence emission wavelength for these samples. This highlights how octahedral tilting plays a major role in determining the optical bandgap and suggests that miniband formation plays only a minor role in this material.
Terahertz Optics Driven Phase Transition in Two-Dimensional Multiferroics

description: Displacive martensitic phase transition is potentially promising in semiconductor based data storage applications with fast switching speed. In addition to traditional phase transition materials, the recently discovered two-dimensional ferroic materials are receiving lots of attention owing to their fast ferroic switching dynamics, which could tremendously boost data storage density and enhance read/write speed. In this study, we propose that a terahertz laser with an intermediate intensity and selected frequency can trigger ferroic order switching in two-dimensional multiferroics, which is a damage-free noncontacting approach. Through first-principles calculations, we theoretically and computationally investigate optically induced electronic, phononic, and mechanical responses of two experimentally fabricated multiferroic (with both ferroelastic and ferroelectric) materials, \b{eta}-GeSe and α-SnTe monolayer. We show that the relative stability of different orientation variants can be effectively manipulated via the polarization direction of the terahertz laser, which is selectively and strongly coupled with the transverse optical phonon modes. The transition from one orientation variant to another can be barrierless, indicating ultrafast transition kinetics and the conventional nucleation-growth phase transition process can be avoidable.

Unravelling the mystery of the M31 bar

name: Beaton, Rachael Lynn
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The inclination of M31 is too close to edge-on for a bar component to be easily recognised and is not sufficiently edge-on for a boxy/peanut bulge to protrude clearly out of the equatorial plane. Nevertheless, a sufficient number of clues allow us to argue that this galaxy is barred. We use fully self-consistent N-body simulations of barred galaxies and compare them with both photometric and kinematic observational data for M31. In particular, we rely on the near infrared photometry presented in a companion paper. We compare isodensity contours to isophotal contours and the light profile along cuts parallel to the galaxy major axis and offset towards the North, or the South, to mass profiles along similar cuts on the model. All these comparisons, as well as position velocity diagrams for the gaseous component, give us strong arguments that M31 is barred. We compare four fiducial N-body models to the data and thus set constraints on the parameters of the M31 bar, as its strength, length and orientation. Our `best' models, although not meant to be exact models of M31, reproduce in a very satisfactory way the main relevant observations. We present arguments that M31 has both a classical and a boxy/peanut bulge. Its pseudo-ring-like structure at roughly 50' is near the outer Lindblad resonance of the bar and could thus be an outer ring, as often observed in barred galaxies. The shape of the isophotes also argues that the vertically thin part of the M31 bar extends considerably further out than its boxy bulge, i.e. that the boxy bulge is only part of the bar, thus confirming predictions from orbital structure studies and from previous N-body simulations.

Subjects: pilots, testing plans, implementation

description: Three industry partners (Proximus, Refinitiv and Deutsche Telekom) describe their pilots and testing plans for components, tools and concepts developed in SPECIAL by the consortium. The pilots and implementation plans are based on previous documents/deliverables (namely D5.1, D5.3 and as well as D5.2, D1.1, D1.2, D1.3, D1.4 and subsequently D2.4, D3.2, D3.3 and D3.6). This document was designed for “staging”, i.e. it was reworked on a regular basis. The present version “Deliverable 5.5 V3” is the third and final iteration and includes implementation plans, results of the (already implemented) pilots and the test plans/results. Due to the different objectives and types of implementation, the industry partners were assigned one chapter each. These chapters may be read relatively independently of each other. However they all have certain aims and findings in common. These are collected in the overarching chapters 2 and 6. Since this work is based on “pilots” (not on products), neither a profound summary nor ultimate conclusions can be expected. The reader is kindly asked to take advantage of the current (mature but still preliminary) state of findings. The present document aims at giving the reader a comprehensive view into the current (final) state of implementation of the pilots, testing plans as well as expected and achieved findings.

description: We formulate a general multi-mode Gaussian operator basis for fermions, to enable a positive phase-space representation of correlated Fermi states. The Gaussian basis extends existing bosonic phase-space methods to Fermi systems and thus enables first-principles dynamical or equilibrium calculations in quantum many-body Fermi systems. We prove the completeness and positivity of the basis, and derive differential forms for products with one- and two-body operators. Because the basis satisfies fermionic superselection rules, the resulting phase space involves only c-numbers, without requiring anti-commuting Grassmann variables.

Lutjanidae.
Southern Red Snapper; Pargo Colorado (Fig. 2H–I).
Diagnosis: This species differs from the other species of the family occurring in the freshwaters of the country (Atlantic) by the following combination of characters: absence of blue iridescent lines or spots below the eye [vs. present in Lutjanus analis (Cuvier, 1828) and Lutjanus griseus (Linnaeus, 1758)]; absence of a black blotch on lateral line (vs. present in L. analis); lateral line scales 47–51 (vs. 43–47 in L. griseus); gill rakers on the lower gill arch 14–16 [vs. 12–14 in the other species); profile of anal fin angulate, with the middle rays prolonged [vs. rounded, without the middle rays prolonged in L. griseus and Lutjanus jocu (Bloch & Schneider, 1801)]; and juveniles with a dark oblique stripe from snout through eye to top corner of operculum (not present in the other species).
Basis of the record: Three specimens were captured in the Matina River basin. Two in the Quebrada Hone Creek/río Carbón, Talamanca, Limón (9.67153, -82.79047), at 12 m. a.s.l., on October 6, 2007, by Maribel Mafla et al. (UCR 2751-001). Another specimen was captured in the río Moín, at the Puerto Fluvial JAPDEVA, Limón (09.99745, -83.08077), at 7 m. a.s.l., on December 14, 2006, by Karina Rodríguez (UCR 2761-003).
Remarks: This species inhabits estuarine areas and coastal environs, including rocky and coral reefs; it could be considered as an opportunistic visitor of freshwater ecosystems (Robertson & Van Tassell 2019).

description: We examine the dynamics of inflation driven by multiple, interacting scalar fields and derive a multi field version of the Hubble slow roll expansion. We show that the properties of this expansion naturally generalize those of the single field case. We present an analogous hierarchy of slow roll parameters, and derive the system of ``flow'' equations that describes their evolution, and show that when this system is truncated at finite order, it can always be solved exactly. Lastly, we express the scalar and tensor perturbation spectra in terms of the slow roll parameters.

description: The heating of inertial confinement fusion (ICF) target by fast electrons, which are generated as a result of laser interaction with expanding plasma (corona) of a target, is investigated theoretically. It is shown that due to remoteness of the peripheral region, where electrons are accelerated, a significant portion of these particles, moving in corona and repeatedly crossing it due to reflection in a self-consistent electric field, will not hit into the compressed part of target. Using the modern models of fast electron generation, it is shown that in a typical target designed for spark ignition, the fraction of fast electrons that can pass their energy to compressed part of target is enough small. Only 12% of the total number of fast electrons can do it. Such an effect of 'wandering' of fast electrons in corona leads to a significant decrease in a negative effect of fast electrons on target compression. Taking into account the wandering effect, the distribution of energy transmitted by fast electrons to different parts of target and the resulting reduction of deuterium-tritium (DT) fuel compression are established.

description: The ``optical springs'' regime of the signal-recycled configuration of laser interferometric gravitational-wave detectors is analyzed taking in account optical losses in the interferometer arm cavities. This regime allows to obtain sensitivity better than the Standard Quantum Limits both for a free test mass and for a conventional harmonic oscillator. The optical losses restrict the gain in sensitivity and achievable signal-to-noise ratio. Nevertheless, for parameters values planned for the Advanced LIGO gravitational-wave detector, this restriction is insignificant.

description: We present Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 observations of dust continuum emission of the disk around WW Cha. The dust continuum image shows a smooth disk structure with a faint (low-contrast) dust ring, extending from $\sim 40$ au to $\sim 70$ au, not accompanied by any gap. We constructed the simple model to fit the visibility of the observed data by using MCMC method and found that the bump (we call the ring without the gap the bump) has two peaks at $40$ au and $70$ au. The residual map between the model and observation indicates asymmetric structures at the center and the outer region of the disk. These asymmetric structures are also confirmed by model-independent analysis of the imaginary part of the visibility. The asymmetric structure at the outer region is consistent with a spiral observed by SPHERE. To constrain physical quantities of the disk (dust density and temperature), we carried out radiative transfer simulations. We found that the midplane temperature around the outer peak is close to the freezeout temperature of CO on water ice ($\sim 30$ K). The temperature around the inner peak is about $50$ K, which is close to the freezeout temperature of H$_2$S and also close to the sintering temperature of several species. We also discuss the size distribution of the dust grains using the spectral index map obtained within the Band 6 data.

description: We search for strange pentaquark states that have been previously reported by other experiments -- the $Θ(1540)^+$, $Ξ_5(1860)^{--}$, and $Ξ_5(1860)^0$ -- in 123 fb$^{-1}$ of data recorded with the BaBar detector at the PEP-II $e^+e^-$ storage ring. We find no evidence for these states and set 95% confidence level upper limits on the number of $Θ(1540)^+$ and $Ξ_5(1860)^{--}$ pentaquarks produced per $e^+e^-$ annihilation event that are about eight and four times lower than the rates measured for ordinary baryons of similar mass.

description: WC-Co cemented carbides (hardmetals) are a group of composite materials exhibiting outstanding
combinations of hardness and toughness. As a consequence, they are extensively used for highly
demanding applications, such as cutting and drilling tools, where cyclic loading is one of the most
critical service conditions.
A numerical study of the mesoscale fatigue crack growth in WC-Co is here conducted. Within this
context, a model based on a continuum damage mechanics approach was implemented in
commercial solver Abaqus/Explicit for simulating the crack propagation in the material. Separate
damage laws, based on brittle failure and fatigue, were used for describing the mechanical
response of WC and Co phases, respectively. Material parameters for the carbide phase were
taken from literature, whereas those for the metallic phase were experimentally determined in a
model binder-like Co-base alloy, i.e. one with a composition representative of the binder phase
within a commercial hardmetal grade.
In order to validate the approach used, a numerical model based on a real damaged microstructure
was generated. It is found that proposed model is capable of capturing damage evolution with
cyclic loading in WC-Co, as numerical results reflect satisfactory agreement with real crack pattern
resulting from experiments.

Characteristics of organic and elemental carbon in particulate matter on the US East Coast: a case study at metropolitan Newark in New Jersey
Creators: name: Gonzalez, Isbel

Year: 2021

description: To investigate the day- and night-time variability of carbonaceous aerosols in the ambient air in metropolitan Newark in New Jersey on the US east coast, particulate air samples of PM2.5 (particles with diameter ≤2.5 µm) and PM2.5-10 (particles with diameter 2.5-10 µm) were collected from downtown Newark. Air samples were analyzed by thermal-optical analysis methods for elemental carbon (EC) and organic carbon (OC). The results show that the total carbonaceous particulate matter (PM) in the air was dominated by coarse-mode particles. The OC/EC ratios varied from 5.3 to 50.9, with an average of 19.2 ± 11.7 for PM2.5, and from 5.1 to 13.7, averaging 7.5 ± 2.1 for PM2.5-10. Higher concentrations of OC in PM2.5 particles occurred at night with a moderate correlation with Relative Humidity (RH) (R²=0.52), suggesting the possible formation of secondary organic aerosols (SOC) via aqueous-phase oxidation of low volatility organic compounds. Fine-mode OC had moderate correlations with PM2.5 sodium (R2=0.59) and PM2.5-10 sodium (R2=0.37), suggesting a mixed influence of anthropogenic and marine sources. Fine mode EC had a strong relationship with PM2.5 nitrate (R² = 0.75), suggesting an anthropogenic source for PM2.5 EC, as nitrate is a secondary aerosol formed from nitrogen oxides (NOx) emitted mainly by traffic sources. The concentrations of coarse mode EC (PM2.5-10) were higher during the daytime than at night, suggesting a major contribution from mobile sources. The PM10/PM2.5 ratios observed during this study were 4.6 for OC and 7.8 for EC, higher than those from selected previous studies. The highest concentrations of carbonaceous aerosols were associated with east-southeast winds; busy highways were also in that direction, while the concentrations of them were the lowest under west winds. This suggests that winds played an important role in the variations of carbonaceous aerosols in the air in this region.
