Bactris gasipaes

description: Genetic, linguistic, and cultural clues about domesticated plants provide insights into the histories of the people who have developed and used them. This study examines these clues for the peach palm (Bactris gasipaes), a fruiting palm that is native to South America, but was domesticated and dispersed more widely around the continent by indigenous peoples prior to European arrival there. This project interprets the distribution of peach palm terms in indigenous South American languages in comparison to both genetic work on wild and domesticated peach palm varieties (Clement et al., 2017) as well as ethnographic work and historical information on the significance of the peach palm in different indigenous groups. In its linguistic component, this project analyzes lexical data in South American indigenous languages using dictionaries, other published materials, and communication with experts. Ethnographies of indigenous groups illustrate the ceremonial and ritual uses of the peach palm, and may provide additional information about the distribution of peach palm use practices. Finally, this project examines the peach palm’s status in the context of its historical trajectory to identify possible explanations for its lack of global importance, especially compared to other New World crops. By drawing on data and analysis from multiple fields, this project aims to look toward a more complete picture of the peach palm and the people who have used it over time.
The self-dual gauge fields and the domain wall fermion zero modes

description: A new type of gauge fixing of the Coulomb gauge domain wall fermion system that reduces the fluctuation of the effective running coupling and the effective mass of arbitrary momentum direction including the region outside the cylinder cut region is proposed and tested in the $16^3\times 32\times 16$ gauge configurations of RBC/UKQCD collaboration. The running coupling at the lowest momentum point does not show infrared suppression and compatible with the experimental data extracted from the JLab collaboration. The source of the fluctuation of the effective mass near momentum $p=$0.6GeV region is expected to be due to the domain wall fermion zero modes.

The Debt I Owe: Consequences of Criminal-Legal Debt in Metro Atlanta
Creators: name: Pizarro, Daniel
Publisher: name: Georgia State University
Year: 2023

description:
Neoliberalism alters U.S. carceral practices to extract revenue from marginalized communities. The criminal-legal system made monetary sanctions (e.g., cash bail, traffic fines, probation fees) a common practice that affects the millions of people who cycle through the system. I argue that criminal-legal debt extends punishment outside of carceral structures and creates a revolving door effect in which poor, racialized communities are subjected to constant incarceration. Domestic violence cases in Atlanta are a prime example of this phenomenon and illustrates the ways in which incarceration aids neoliberalism. The over policing of minority communities, and by extension the imposition of monetary sanctions, in metro-Atlanta serves to generate revenue and gentrify those neighborhoods. Through a prison abolitionist lens, this research explores the impact of criminal-legal debt in metro-Atlanta through autoethnography, interviews, and online participant observation of court.

description: Considerable effort has been directed towards the characterization of chiral mesoscale structures, as shown in chiral protein assemblies and carbon nanotubes. Here, we establish a thermally-driven hydrodynamic description for the actuation and separation of mesoscale chiral structures in a fluid medium. Cross flow of a Newtonian liquid with a thermal gradient gives rise to chiral structure propulsion and separation according to their handedness. In turn, the chiral suspension alters the liquid flow which thus acquires a transverse (chiral) velocity component. Since observation of the predicted effects requires a low degree of sophistication, our work provides an efficient and inexpensive approach to test and calibrate chiral particle propulsion and separation strategies.
Teaching Truth: Grassroots Reactions to Classroom Censorship Legislation in Georgia
Creators: name: Hugonnet, Emma
Publisher: name: Georgia State University
Year: 2023

description:
Legislation known as anti-CRT bills swept across the United States in 2020 designed to eradicate principles of diversity, equity, inclusion, and oftentimes history from school curriculums. This research employs an engaged anthropological framework to explore the reactions and resistance measures employed by grassroots groups in response to the Protect Students First Act in Georgia. Data analysis utilized over 10 hours of participant observation at events during 2022-2023 in the Atlanta Metropolitan area, in-depth interviews with grassroots leaders from Georgia Educators for Equity and Justice Inc. (GAEEJ) and Teach for Freedom Collective, and surveys provided by GAEEJ on the impacts of legislation on teachers and students, activists motivations for action, and their strategies of resistance. The study reveals that resistance to this legislation is grounded in participants demand for equity and advocacy in schools and takes the form of community-making and capacity-building for successful initiatives against classroom censorship laws.
Community Recovery in Eastern Kentucky after the July 2022 Flooding
Creators: name: Smith, Margaret
Publisher: name: Georgia State University

description:
This thesis addresses the questions of how eastern Kentucky activists understand the July 2022 flooding, its impact on their lives, the lives of flood survivors, and what they and flood survivors want for the future and how eastern Kentucky are communities recovering from disaster. The goal of this research project was to collect community experiences, perspectives, and goals and to document recovery efforts. After analyzing 11 interviews with eastern Kentucky activists and participant observation data, I argue that the structural inequities related to coal mining influenced vulnerability, flood experiences, and recovery efforts. I also argue that the strong sense of community present in eastern Kentucky serves as a basis for improved recovery and resilience efforts. Better understanding the context of the flooding can aid eastern Kentucky activists, flood survivors, and allies in recovering, addressing structural violence, and preparing for the future.

Equal Dignity and the Right to Die: The Outer Boundaries of Due Process

description: The Fourteenth Amendment’s Due Process Clause is one of the most controversial provisions in the Constitution. Although it appears only to guarantee fair procedures, it has become the Court’s primary vehicle for invalidating State laws that violate fundamental liberties—in the practice now known as “substantive due process.” In recent years, though, a line of landmark Supreme Court decisions protecting gay rights, authored by Justice Kennedy, have signaled a new chapter for substantive due process—one where the Due Process Clause works in tandem with the Equal Protection Clause. I argue that the framework employed by Justice Kennedy in these cases differs from the standard substantive due process framework in important ways and constitutes an independent doctrine of equal dignity. This doctrine of equal dignity has major implications for the next generation of substantive due process cases, as it equips the Court to strike down laws that institutionalize subordination. In particular, the Court’s equal dignity precedents single out its 1997 decision in Washington v. Glucksberg, where the Court ruled that laws banning physician-assisted suicide were not unconstitutional. I argue, however, that the doctrine of equal dignity implies the existence of a “right to die with dignity.” Consequently, Glucksberg should be overruled—granting terminally ill patients the right to physician-assisted suicide.

description: We introduce an area operator for the Moyal noncommutative plane. We find that the spectrum is discrete, but, contrary to the expectation formulated by other authors, not characterized by a "minimum-area principle". We show that an intuitive analysis of the uncertainty relations obtained from Moyal-plane noncommutativity is fully consistent with our results for the spectrum, and we argue that our area operator should be generalizable to several other noncommutative spaces. We also observe that the properties of distances and areas in the Moyal plane expose some weaknesses in the line of reasoning adopted in some of the heuristic analyses of the measurability of geometric spacetime observables in the quantum-gravity realm.

description: We present near-IR photo-spectroscopy in the H and K bands of the 2006 outburst of the recurrent nova RS Ophiuchi (RS Oph). The observations cover the period between 1 to 94 days after the eruption. The near IR light curve and an extensive set of spectra are presented, lines identified and the general characteristics of the spectra discussed. Analysis of the HI line profiles show the presence of broad wings on both flanks of a strong central component indicating the presence of a bipolar velocity flow in the ejecta. Such a flow is kinematically consistent with the bipolar structure that the object displays in high-resolution spatial images. We discuss the behaviour and origin of the Fe II lines at 1.6872 and 1.7414 micron and show that Lyman alpha and Lyman continuum fluorescence are viable mechanisms to excite these lines. We draw upon the result, that collisional excitation can also contribute in exciting and significantly enhancing the strength of these Fe II lines, to propose that these lines originate from a site of high particle density. Such a likely site could be the high-density, low temperature contact surface that should exist in the shockfront in between the shocked ejecta and red giant wind. Recombination analysis of the HI lines indicate deviations from Case B conditions during most of the span of our observations indicating optical depth effects. It appears likely that the breakout of the shockfront had not yet occured till the end of our observations. An analysis is made of the temporal evolution of the [Si VI] 1.9641 micron coronal line and another coronal line at 2.0894 micron which is attributed to [Mn XIV]. Assuming collisional effects to dominate in the hot coronal gas, estimates are made of the ion temperature in the gas.

Do we understand the incompressibility of neutron-rich matter?

description: The ``breathing mode'' of neutron-rich nuclei is our window into the incompressibility of neutron-rich matter. After much confusion on the interpretation of the experimental data, consistency was finally reached between different models that predicted both the distribution of isoscalar monopole strength in finite nuclei and the compression modulus of infinite matter. However, a very recent experiment on the Tin isotopes at the Research Center for Nuclear Physics(RCNP) in Japan has again muddled the waters. Self-consistent models that were successful in reproducing the energy of the giant monopole resonance (GMR) in nuclei with various nucleon asymmetries (such as 90Zr, 144Sm, and 208Pb) overestimate the GMR energies in the Tin isotopes. As important, the discrepancy between theory and experiment appears to grow with neutron excess. This is particularly problematic as models artificially tuned to reproduce the rapid softening of the GMR in the Tin isotopes become inconsistent with the behavior of dilute neutron matter. Thus, we regard the question of ``why is Tin so soft?'' as an important open problem in nuclear structure.

Investigating the DNA repair-ubiquitin proteasome system as a therapeutic target for pancreatic and ovarian cancers
Creators: name: Astuti, Yuliana
Publisher: name: Imperial College London
Year: 2018

description: Pancreatic ductal adenocarcinoma (PDAC) and ovarian cancer (OC) are malignancies with poor prognosis, partially due to resistance to the currently available therapies. siRNA screening previously carried out in the laboratory identified a role for the chaperone protein valosin- containing protein (VCP) in maintaining PDAC and OC cell survival. This study aims to examine the potential of VCP as a novel therapeutic target for these cancers by assessing the in vitro efficacy and cellular effects of VCP inhibitors (CB-5083 and NMS-873) in a PDAC and OC cell line panel. A range of sensitivities was found to the VCP inhibitors, and the response to both was associated with the levels of proteotoxic stress induced. CB-5083 induced both the adaptive and apoptotic unfolded protein responses (UPR) and the extent of these responses was dependent on the proteotoxic levels. In comparison, NMS-873 induced the apoptotic UPR more strongly than the adaptive response, but no clear association between levels of apoptotic UPR marker and proteotoxic levels/sensitivity was observed. Furthermore, response to CB-5083 was also found to negatively correlate with baseline expression of the VCP protein. Analysis of the effect of combining cisplatin and NMS-873 indicated potential synergy can be achieved in most PDAC and OC cell lines. Examination into the mechanism of chemo- enhancement by VCP inhibition identified decreased activity of homologous recombination (HR) and loss of Rad51 protein. Further investigation into this identified both transcriptional and non- transcriptional effects of VCP inhibition on Rad51 protein levels. Furthermore, inhibition of PIKK-mediated phosphorylation of VCP was found to increase sensitivity to this drug, potentially by preventing Rad51 degradation. Overall, this study highlights the potential anti-tumour activity of VCP inhibitors in PDAC and OC and has identified potential predictive and pharmacodynamic biomarkers for these inhibitors. Additionally, this study demonstrated VCP inhibition may be a suitable approach to enhance response to cisplatin. Future studies to confirm these findings in a larger panel of cell lines, as well as in vivo, will further establish the viability of VCP inhibition as therapeutic strategy in PDAC and OC.

description: Making use of focused Ga-ion beam (FIB) fabrication technology, the evolution with device dimension of the low-temperature electrical properties of Nb nanowires has been examined in a regime where crossover from Josephson-like to insulating behaviour is evident. Resistance-temperature data for devices with a physical width of order 100 nm demonstrate suppression of superconductivity, leading to dissipative behaviour that is shown to be consistent with the activation of phase-slip below Tc. This study suggests that by exploiting the Ga-impurity poisoning introduced by the FIB into the periphery of the nanowire, a central superconducting phase-slip nanowire with sub-10 nm dimensions may be engineered within the core of the nanowire.

Investigating the role of SOCS1 in asthma exacerbations
Creators: name: Strong, Katherine
Publisher: name: Imperial College London
Year: 2019

description: Asthma exacerbations are frequently caused by respiratory viral infection, most commonly rhinoviruses, in up to 80% of cases. Virus-induced asthma exacerbations have been associated with increased type 2 airway inflammation and impaired interferon induction, however the mechanisms driving virus-induced asthma exacerbations are not well understood. Suppressor of cytokine signalling 1 (SOCS1) is an inhibitor of both interferon signalling and induction and is induced by the cytokines IL-4 and IL-13. This thesis sought to investigate if SOCS1 expression is increased in asthmatic bronchial epithelial cells and if SOCS1 is associated with impaired interferon responses or worse symptoms upon rhinovirus infection. In bronchial biopsies from atopic asthmatics, SOCS1 expression was associated with worse symptoms and greater falls in lung function upon rhinovirus infection. However, in cultured bronchial epithelial cells, there was no difference in SOCS1 mRNA expression between atopic asthmatics or healthy controls. In bronchial biopsies and cultured bronchial epithelial cells, skin prick test positivity was associated with increased SOCS1 expression and induction, respectively. This thesis has also shown that IL-4 and rhinovirus interact to increase SOCS1 expression; IL-4 induces SOCS1 via activation of the adjacent promoter, while rhinovirus functions through a distinct and uncharacterised mechanism, which may involve distal regulatory elements. The knockout of SOCS1 in a fibroblast cell line enhanced rhinovirus-induced interferon induction. However, this thesis was unable to demonstrate a role for nuclear SOCS1 in inhibiting rhinovirus-induced interferon or determine if IL-4 or rhinovirus increases the nuclear localisation of SOCS1. Collectively, these findings support the hypothesis that increased SOCS1 is associated with worse clinical outcome following rhinovirus infection. These findings support a role for increased type 2 inflammation in enhancing SOCS1 expression, which may be of interest in asthma exacerbations. The identification of the precise mechanism by which SOCS1 is induced and undergoes nuclear localisation will require further study.
Cancer as a systemic disease: Investigating tumour-host interaction in drosophila
Creators: name: Newton, Holly
Publisher: name: Imperial College London
Year: 2019

description: A complex and bi-directional interaction exists between a tumour and its host. By treating cancer as a systemic disease, and leveraging the genetic tractability of Drosophila melanogaster, work throughout this thesis explores the nature of the tumour-host interaction. By combining Drosophila models of high sugar diet (HSD)-induced obesity and Ras/Src-driven tumourigenesis, I have established a model of ‘cachexia-like’ systemic muscle wasting. This model system has provided an excellent opportunity to explore the metabolic/nutritional interplay between tumourigenesis, HSD-induced obesity, and host systemic muscle wasting. This thesis specifically addresses two questions. Firstly, how does a tumour impact host systemic metabolism? And secondly, how do host metabolic alterations and their associated effects on systemic nutrient availability, impact tumour growth? I identify Branchless (Bnl), a Drosophila Fibroblast Growth Factor (FGF), as a tumour- and hostderived mediator of systemic muscle wasting. I highlight a perturbed systemic metabolic profile, characterised by amino acid mobilisation and elevated levels of circulating amino acids as one of the key consequences of systemic muscle wasting. This altered systemic amino acid profile has functional effects on tumour growth; elevated levels of circulating L-proline promote tumour growth via tumour-autonomous SLC36-family amino acid transporter expression. This establishes a tumour-host circuitry which requires two levels of coordination: (i) at the whole organism level— by promoting cachexia-like muscle wasting and systemic amino acid availability, and (ii) at the tumour-autonomous level—by modulating amino acid transporter repertoire. Furthermore, I highlight our approach of combining mechanistic insights from whole-animal Drosophila studies, with human cancer database analysis and human in vitro data to rationally target the nutrient vulnerabilities of tumourigenesis. Overall, this uncovers a novel concept and mechanism by which tumours exploit extracellular nutrients in response to systemic muscle wasting. This work therefore represents a new layer of tumour-host metabolic crosstalk which adds to our ever-growing appreciation of the intricacies of tumour-host interaction.

description: We argue that there is a special doping point in the phase diagram of cuprates, such that the condensation of holes into a charge-ordered and into a superconducting phase are degenerate in energy but with an energy barrier in between. We present a Monte Carlo simulation of this problem without and with quenched disorder. While in the clean case charge order and superconductivity are separated by a first-order line which is nearly independent of temperature, in the presence of quenched disorder, charge order is fragmented into domains separated by superconducting filaments reminiscent of the supersolid behavior in $^4$He. The resulting phase diagram is in good agreement with the experiments.

Aquatic escape for micro-aerial vehicles
Creators: name: Zufferey, Raphael
Publisher: name: Imperial College London
Year: 2019

description: As our world is experiencing climate changes, we are in need of better monitoring technologies. Most of our planet is covered with water and robots will need to move in aquatic environments. A mobile robotic platform that possesses eﬃcient locomotion and is capable of operating in diverse scenarios would give us an advantage in data collection that can validate climate models, emergency relief and experimental biological research. This ﬁeld of application is the driving vector of this robotics research which aims to understand, produce and demonstrate solutions of aerial-aquatic autonomous vehicles. However, small robots face major challenges in operating both in water and in air, as well as transition between those ﬂuids, mainly due to the diﬀerence of density of the media. This thesis presents the developments of new aquatic locomotion strategies at small scales that further enlarge the operational domain of conventional platforms. This comprises ﬂight, shallow water locomotion and the transition in-between. Their operating principles, manufacturing methods and control methods are discussed and evaluated in detail. I present multiple unique aerial-aquatic robots with various water escape mechanisms, spanning over diﬀerent scales. The ﬁve robotic platforms showcased share similarities that are compared. The take-oﬀ methods are analysed carefully and the underlying physics principles put into light. While all presented research fulﬁls a similar locomotion objective - i.e aerial and aquatic motion - their relevance depends on the environmental conditions and supposed mission. As such, the performance of each vehicle is discussed and characterised in real, relevant conditions. A novel water-reactive fuel thruster is developed for impulsive take-oﬀ, allowing consecutive and multiple jump-gliding from the water surface in rough conditions. At a smaller scale, the escape of a milligram robotic bee is achieved. In addition, a new robot class is demonstrated, that employs the same wings for ﬂying as for passive surface sailing. This unique capability allows the ﬂexibility of ﬂight to be combined with long-duration surface missions, enabling autonomous prolonged aquatic monitoring.
Gendered Division of Labor among the Late Woodland Iroquois: Lithic Scrapers and Hide Production at the Simmons Site, New York
Creators: name: Hart, Brittany
Publisher: name: Georgia State University
Year: 2023

description:
Among the Iroquois, hide processing is a highly gendered practice dominated by women. Due to the egalitarian structure of Iroquois villages, work is often distributed equally among individuals based on Iroquois gender roles. The village and surrounding areas are divided into spatial domains comprised of gendered controlled activities such as hide processing. Examining these domains through a task differentiation approach makes it possible to associate artifacts within the archaeological record with gendered labor division. Drawing on ethnohistoric and ethnographic data, this thesis analyzes gendered labor division at the Simmons Site, a Late Woodland Period (AD 900-1650) village in Elma, New York. Additionally, I highlight similarities and differences in how gendered practices were constructed and experienced by the residents of Iroquoian sites within the region. This research challenges previous gendered task differentiation models to ensure that the roles and contributions of Iroquoian women are represented in future archaeological analysis and interpretation.

A new technique for tensile testing of high performance engineering material
Creators: name: Zhou, Junyi
Publisher: name: Imperial College London
Year: 2019

description: The thesis describes a new test technique and an associated bespoke apparatus to conduct tensile testing at high strain rates and in environmentally-controlled conditions. The technique is suitable to measure the dynamic tensile response of brittle materials difficult to grip (brittle solids and materials in the form of fibre yarns or tapes) and of ring-shaped specimens. The apparatus is compact in size and shape, and this facilitates testing in a conditioned atmosphere. The method also offers the advantage that identical specimens are used in all tests (across wide ranges of strain rate and temperature). The technique allows the measurement of the tensile response of monolithic poly(methyl methacrylate) (PMMA) and unidirectional composites based on Dyneema® tape, Dyneema® SK75 yarn and Kevlar® 49 yarn. The measurements are conducted in a wide range of strain rate (0.0001-323/s ) and yield valid dynamic stress versus strain histories, including part of the elastic material response. Valid stress-strain curves for Dyneema® tape and Dyneema® SK75 yarn are obtained for the first time. We then extend this technique to conduct experiments at low strain rates and at temperatures in the range -40 to 70°C. The sensitivities of the tensile properties to strain rate and temperature are effectively correlated using the time-temperature equivalence principle. A numerical investigation is conducted to assess the suitability of this technique for both Hopkinson bar tests and projectile impact experiments, allowing tests at ultra-high strain rates (> 1000/s).

description: PAHs have been detected toward molecular clouds and some young stars with disks, but have not yet been associated with embedded young stars. We present a sensitive mid-IR spectroscopic survey of PAH features toward a sample of low-mass embedded YSOs. The aim is to put constraints on the PAH abundance in the embedded phase of star formation using radiative transfer modeling. VLT-ISAAC L-band spectra for 39 sources and Spitzer IRS spectra for 53 sources are presented. Line intensities are compared to recent surveys of Herbig Ae/Be and T Tauri stars. The radiative transfer codes RADMC and RADICAL are used to model the PAH emission from embedded YSOs consisting of a PMS star with a circumstellar disk embedded in an envelope. The dependence of the PAH feature on PAH abundance, stellar radiation field, inclination and the extinction by the surrounding envelope is studied. The 3.3 micron PAH feature is undetected for the majority of the sample (97%), with typical upper limits of 5E-16 W/m^2. Compact 11.2 micron PAH emission is seen directly towards 1 out of the 53 Spitzer Short-High spectra, for a source that is borderline embedded. For all 12 sources with both VLT and Spitzer spectra, no PAH features are detected in either. In total, PAH features are detected toward at most 1 out of 63 (candidate) embedded protostars (

description: Exfoliated graphene monolayers are identified by optical inspection. In order to improve the monolayer detection, we investigate the angle dependence of the optical contrast of graphene on a 90nm SiO$_2$/Si substrate. We observe a significant enhancement of the visibility of graphene by changing the polarization and the angle of optical incidence. This method can be used to detect graphene on new substrate designs such as GaAs/AlAs based materials, which have a much cleaner surface.

title: Sexual Dimorphism of the Second Cervical Vertebra in Humans
Creators: name: Paskins, Morgan
Publisher: name: Georgia State University
Year: 2023

description:
The pelvis and skull are frequently examined for the expression of sex-linked traits as are the humeral and femoral head dimensions. The second vertebra allows for rotation of the head, which is larger in males than in females. The axis is positioned close to other traits that have been shown to exhibit dimorphism, such as the mastoid process, gonial region, nuchal area, and the occipital protuberance. To explore which dimensions of the axis differ the most between females and males, and investigate its relationship to age, 149 individuals from the W.M. Bass Osteological Collection at the University of Tennessee, Knoxville were measured using 13 linear distances. The three age cohorts included 30-35, 50-55, and 70-75 years. The results indicate that all the traits show significant differences between the sexes. Using discriminant function analysis, predictive functions were created to estimate the sex of unknown individuals using 6 traits, 4 traits, 3 traits and 2 traits.

Year: 2017

description: Many colleges and universities have created learning commons that bring together library, computing, and other campus services to support students’ academic work. Mitchell and Bell describe the creation of a learning commons that became not only a place to access academic services, but also a focal point for student leadership and holistic support. Mitchell and Bell show how UBC’s work is grounded in student development theory and cuts across traditional unit-based structures to be truly collaborative. The authors also provide advice and reflective questions to guide those who would like to undertake similar collaborations.

Today, there are many potential threats that are targeted at storage networks, including data modification, destruction and theft, DoS attacks, malware, hardware theft and unauthorized access, among others. In order for a Storage Area Network (SAN) to be secure, each of these threats must be individually addressed. In this paper, we present a comparative study by implementing different security methods in IP Storage network.

description: The evaluation of the formative process in the University system has been assuming an ever increasing importance in the European countries. Within this context the analysis of student performance and capabilities plays a fundamental role. In this work we propose a multivariate latent growth model for studying the performances of a cohort of students of the University of Bologna. The model proposed is innovative since it is composed by: (1) multivariate growth models that allow to capture the different dynamics of student performance indicators over time and (2) a factor model that allows to measure the general latent student capability. The flexibility of the model proposed allows its applications in several fields such as socio-economic settings in which personal behaviours are studied by using panel data.

description: The direct product of sporadic simple groups is a rather large group of the approximate order of 2.33×10^365, describing an object of d = 93.75 billion ly and weight of 9.63 × 10^53 kg, composed out of 6.15 × 10^121 3D knots - particles. This is the same weight as two classical electrons at Planck density minus the weight of all baryonic matter inside a local (late time) Hubble volume. The Compton wavelength of all baryonic matter inside the observable universe at maximum expansion is directly related to the order of this group. Two values of Hubble's constant (Hubble tension) are recovered. Proton/electron mass ratio is recovered assuming precise baryonic matter/total matter ratio of 1/2π, which is inside contemporary estimates. This group is implicated as a source of Weyl-Dirac's-Funkhouser's large numbers.

description: We consider the AdS_5 x S^5 superstring in the light-cone gauge adapted to a massless geodesic in AdS5 in the Poincare patch. The resulting action has a relatively simple structure which makes it a natural starting point for various perturbative quantum computations. We illustrate the utility of this AdS light-cone gauge action by computing the 1-loop and 2-loop corrections to the null cusp anomalous dimension reproducing in a much simpler and efficient way earlier results obtained in conformal gauge. This leads to a further insight into the structure of the superstring partition function in non-trivial background.

Contact and Friction of Nano-Asperities: Effects of Adsorbed Monolayers

description: Molecular dynamics simulations are used to study contact between a rigid, nonadhesive, spherical tip with radius of order 30nm and a flat elastic substrate covered with a fluid monolayer of adsorbed chain molecules. Previous studies of bare surfaces showed that the atomic scale deviations from a sphere that are present on any tip constructed from discrete atoms lead to significant deviations from continuum theory and dramatic variability in friction forces. Introducing an adsorbed monolayer leads to larger deviations from continuum theory, but decreases the variations between tips with different atomic structure. Although the film is fluid, it remains in the contact and behaves qualitatively like a thin elastic coating except for certain tips at high loads. Measures of the contact area based on the moments or outer limits of the pressure distribution and on counting contacting atoms are compared. The number of tip atoms making contact in a time interval grows as a power of the interval when the film is present and logarithmically with the interval for bare surfaces. Friction is measured by displacing the tip at a constant velocity or pulling the tip with a spring. Both static and kinetic friction rise linearly with load at small loads. Transitions in the state of the film lead to nonlinear behavior at large loads. The friction is less clearly correlated with contact area than load.

The role of inflammation, stem cells and progenitor cells in cardiovascular repair
Creators: name: Mutoli, Martina
Publisher: name: Zenodo
Year: 2024

description: This editorial features the collection of articles published in Frontiers in Cardiovascular Medicine: The role of Inflammation, Stem Cells and Progenitor Cells in Cardiovascular Repair. Myocardial infarction (MI) is the leading cause of death worldwide. After MI, immune cells, both tissue-resident and those recruited from the circulation, act to clear the dead cells and instruct the repairing process. However, the activated immune cells also cause chronic inflammation, which may aggravate the tissue damage, including aberrant healing finally resulting in fibrosis. Indeed, the role of inflammatory cells appears to be double edge: at first instance, inflammation acts as a host-dependent rescue/defense mechanism (in the acute phase); later on (in the chronic phase) inflammation turns into a damaging phenomenon for the host organism. These aspects are objects of the articles contributing to this collection that are briefly summarized in this editorial.
