The 'Egyptianisation' of Nubia: a historiographical review of a persistent concept in Egyptology
Creators: name: Wilkinson-Bibicos, Charlotte Maeve
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: From as early as the Nineteenth Century, ancient Nubia has been viewed through an Egyptological lens. Consequently, Egypto-centric perspectives have often underpinned the study of Nubia with cultural achievements and complexity recognised only in relation to ancient Egypt’s role in the colonisation of Lower Nubia. This perspective has contributed to an enduring disciplinary perception of Nubia as secondary to ancient Egypt, which is itself viewed by Egyptology as the superior and dominating agent. A critical part of this approach has been Egyptology’s use of the term ‘Egyptianisation’, which refers to the supposedly unidirectional process of Nubian cultural change following contact with Egypt. This concept has underpinned scholarly approaches to the study of Nubian and Egyptian interactions for over a century. Recent research has questioned the relevance of ‘Egyptianisation’, suggesting its replacement with a counter-colonial model of ‘cultural entanglement’. Despite this revision, the broader impact of Egyptology’s use of the Egyptianisation model on disciplinary approaches to Nubia needs further consideration. Consequently, this thesis provides a historiographical review of ‘Egyptianisation’ by investigating its origins, theoretical development and assumptions in order to determine what features of Egyptianisation remain in current approaches to Nubian and Egyptian intercultural contact. Despite growing recognition of the colonial and Egypto-centric nature of Egyptianisation, the concept persists in some current academic discourse. Specifically, the assumption that Nubians aspired towards Egyptian cultural practices remains in scholarly discussions surrounding periods of colonial contact. Furthermore, ancient Nubian social identities are still defined against their Egyptian counterparts. The results of this analysis suggest that simply replacing a problematic concept in historiography, or even abandoning it, does not necessarily recognise or repair its influence on a discipline. Furthermore, the significance of these findings has the potential to extend beyond the discipline of Egyptology and concerns current Nubian people today with implications for their historical agency and representations of their cultural identities.

description: We calculate the nuclear magnetic resonance (NMR) response of a quantum wire where at low temperature a self-sustained electron-nuclear spin order is created. Our model includes the electron mediated Ruderman-Kittel-Kasuya-Yosida (RKKY) exchange, electron spin-orbit interactions, nuclear dipolar interactions, and the static and oscillating NMR fields, all of which play an essential role. The paramagnet to helimagnet transition in the nuclear system is reflected in an unusual response: it absorbs at a frequency given by the internal RKKY exchange field, rather than the external static field, whereas the latter leads to a splitting of the resonance peak.

description: Structural and electronic properties of zinc blende TlxIn(1-x)N alloy have been evaluated from first principles. The band structures have been obtained within the density functional theory (DFT), the modified Becke-Johnson (MBJLDA) approach for the exchange-correlation potential, and fully relativistic pseudopotentials. The calculated band-gap dependence on Tl content in this hypothetical alloy exhibits a linear behaviour up to the 25 % of thalium content where its values become close to zero. In turn, the split-off energy at the Gamma point of the Brillouin zone, related to the spin-orbit coupling, is predicted to be comparable in value with the band-gap for relatively low thalium contents of about 5 %. These findings suggest TlxIn(1-x)N alloy as a promising material for optoelectronic applications. Furthermore, the band structure of TlN reveals some specific properties exhibited by topological insulators.

description: Aims. The aim is to derive accurate stellar distances and extinctions for young stars of our survey in the Galactic anticenter direction using the Strömgren photometric system. This will allow a detailed mapping of the stellar density and absorption toward the Perseus arm. Methods. We developed a new method for deriving physical parameters from Strömgren photometry and also implemented and tested it. This is a model-based method that uses the most recent available stellar atmospheric models and evolutionary tracks to interpolate in a 3D grid of the unreddened indexes [m1], [c1] and Hbeta. Distances derived from both this method and the classical pre-Hipparcos calibrations were tested against Hipparcos parallaxes and found to be accurate. Results. Systematic trends in stellar photometric distances derived from empirical calibrations were detected and quantified. Furthermore, a shift in the atmospheric grids in the range Teff=[7000,9000]K was detected and a correction is proposed. The two methods were used to compute distances and reddening for about 12000 OBA-type stars in our Strömgren anticenter survey. Data from the IPHAS and 2MASS catalogs were used to complement the detection of emission line stars and to break the degeneracy between early and late photometric regions. We note that photometric distances can differ by more than 20%, those derived from the empirical calibrations being smaller than those derived with the new method, which agree better with the Hipparcos data.

description: We developed ‘Kikoeru’, a pedometer and communication application (app) for older people, with functions that include voice conversations and messages, photograph sharing, and pedometer sharing among users. This pilot study aimed to clarify the effects of Kikoeru on social connectedness related to interactions through the app, subjective health, loneliness, and setting a target number of steps for seven men aged 65 and older who lived at home. Survey items consisted of the Ando-Osada-Kodama loneliness scale, target number of steps, and subjective health ratings. We utilized interviews, seeking to determine whether users felt connected when using the app. The app usage days were collected from the server. The social and physical effects of the app were assessed using a mix of quantitative and qualitative methods. Participants used the app for 54.9 days on average during the 60-day intervention period. Interviews revealed four social connectedness benefits: ‘constructing reliance’, ‘remembering to consider friends’, ‘awareness of friends’ daily lives and encouragement for me’, and ‘taking an interest in friends’. Loneliness decreased for four out of seven people, remained the same for three, and did not worsen for anyone. The target number of steps increased for three people, remained the same for four, and did not decrease for anyone. Average subjective health improved from 63.6 to 72.9 points out of 100 after the intervention. Results showed participants experienced social connectedness, reduced loneliness, and improved their target steps and health by using Kikoeru. Future large-scale studies with expanded sample sizes should be conducted.

description: Diffusion in bidisperse Brownian hard-sphere suspensions is studied by Stokesian Dynamics (SD) computer simulations and a semi-analytical theoretical scheme for colloidal short-time dynamics, based on Beenakker and Mazur's method [Physica 120A, 388 (1983) & 126A, 349 (1984)]. Two species of hard spheres are suspended in an overdamped viscous solvent that mediates the salient hydrodynamic interactions among all particles. In a comprehensive parameter scan that covers various packing fractions and suspension compositions, we employ numerically accurate SD simulations to compute the initial diffusive relaxation of density modulations at the Brownian time scale, quantified by the partial hydrodynamic functions. A revised version of Beenakker and Mazur's $δγ$-scheme for monodisperse suspensions is found to exhibit surprisingly good accuracy, when simple rescaling laws are invoked in its application to mixtures. The so-modified $δγ$ scheme predicts hydrodynamic functions in very good agreement with our SD simulation results, for all densities from the very dilute limit up to packing fractions as high as $40\%$.

description: The privacy paradox suggests that privacy concerns do not relate to privacy-related behavior. Although it has inspired numerous studies, findings remain inconclusive. Some of the inconsistencies in published findings may be explained by a strong heterogeneity in the conceptual and analytical choices that researchers implement when investigating the privacy paradox. Based on representative survey data of the 27 EU member states (2011: n = 8,962; 2015: n = 10,526; 2019: n = 11,428), I investigated the effect of conceptual and analytical decisions on ‘finding’ the privacy paradox. Specification curve analyses revealed that the magnitude and statistical significance of the relationship between privacy concerns and information disclosure is contingent on the operationalization of the independent variable, the inclusion of covariates, and the age of the studied population. The relationship between online privacy concerns and using social media privacy settings, in contrast, was less influenced by analytical decisions. Yet, the relationship was stronger in younger people and increased over time. The findings call for more transparency in analyzing research data. Evaluating the implications of analytical choices will help to establish best practices and advance cumulative knowledge creation in privacy research.

description: A community-powered shared calendar, the Open Research Calendar, can enable interested users to keep track of open research events. This calendar can help researchers find workshops, conferences and seminars on open research without an effortful search, and minimise the need for scattered manual updates via community-powered automated communication. The Open Research Calendar provides event organisers with an easy solution to promote their event, reaching a larger audience through this central advertisement portal than they could using traditional channels of event promotion such as newsletters, blogs and websites. The Open Research Calendar project addresses these issues through a community Google calendar, which can be synced into a person’s own personal calendar and is automatically updated as new events are added. Events can be added by anyone through entering the key information into a short Google form. This information generates an automated Tweet from the Twitter account (@OpenResearchCal) to notify followers of the calendar about the new event. The more than 500 followers of the calendar indicate that there is a real need for this tool. The current aims of the project are to increase awareness and encourage submission of events. The code and documentation for the calendar is open source and shared with a GNU 3.0 license, so we invite groups to recreate the automation and communication features for their own communities. We welcome contributions to the technical development of the calendar via our public GitHub repository (https://github.com/openresearchcalendar/).

The ecology and evolution of life history trait divergence in Panicum hallii

description: Exploring the process of local adaptation is important to understand how environmental variation can drive phenotypic and genetic differentiation as a response to selection. One hypothesis is that local adaptation results from genetic trade-offs in which locally favored alleles reduce fitness elsewhere to provide environment specific fitness advantage. However, studies that aimed to explain local adaptation in plants were mostly done by transplanting seedlings and avoided the important aspects of divergence in earlier life stages. In this thesis, I assess local adaptation from seed and seedling perspective using Panicum hallii, a C4 perennial grass endemic to North America. This is a wonderful system to study local adaptation as it spreads to a wide range of climatic conditions. By combining field and lab-based experiment, I showed that the seed and seedling transition is important for adaptation. The pattern of genetic architecture at seed and seedling traits suggests that the differentiation was primarily due to genetic pleiotropy or linkage disequilibrium. I also discovered the evidence of antagonistic pleiotropy at two loci for seed size and dormancy traits (Chapter-1). I later tested whether the seed size and dormancy trait combination evolved as correlational selection by doing a complex reciprocal transplantation at two representative habitats. My data showed that both seed size and dormancy traits are important for adaptation to native habitats, suggesting that correlational selection is important for adaptation to different habitats. I also showed that soil surface disturbance had a significant effect on the recruitments, plants adapted to high competitive habitat was favored in undisturbed plot and the opposite was observed for the plants adapted in dry, calcareous soil (Chapter-2). Finally, I looked at natural diversity population to estimate the impact of different seed size strategies for adaptation in different habitats. Our data exhibited that the ecotypic differentiation in P. hallii were strongly associated with seed size and seed size was under strong selection pressure for adapting at variable sites (Chapter-3). Overall, this dissertation showed that seed and seedling traits are extremely important for adaptation in different habitats and the variation in these traits significantly impact life history strategies in P. hallii.

description: We follow the mass expelled during the WD-WD merger process in a particular case of the Double-Degenerate (DD) scenario for Type Ia supernovae (SNe Ia), and find that the interaction of the SN ejecta with the resulting wind affects the early (first day) light curve in a way that may be in conflict with some SN Ia observations, if the detonation occurs shortly after the merger (i.e., $10^3~{\rm sec} \lesssim t_{\rm exp} \lesssim 1~{\rm day}$). The main source of the expelled mass is a disk-wind, or jets that are launched by the accretion disk around the more massive WD during the viscous phase of the merger. This disk-originated matter (DOM) will be shocked and heated by the SN ejecta from an explosion, leading to additional radiation in the early lightcurve. This enhanced early radiation could then be interpreted as an explosion originating from a progenitor having an inferred radius of one solar radius or more, in conflict with observations of SN 2011fe.

description: An interpolating function $\tilde F$ between the $a$-anomaly coefficient in even dimensions and the free energy on an odd-dimensional sphere has been proposed recently and is conjectured to monotonically decrease along any renormalization group flow in continuous dimension $d$. We examine $\tilde F$ in the large-$N$ CFT's in $d$ dimensions holographically described by the Einstein-Hilbert gravity in the AdS$_{d+1}$ space. We show that $\tilde F$ is a smooth function of $d$ and correctly interpolates the $a$ coefficients and the free energies. The monotonicity of $\tilde F$ along an RG flow follows from the analytic continuation of the holographic $c$-theorem to continuous $d$, which completes the proof of the conjecture.

description: In a recent decade, miniaturized optical sensor devices based on photonic integrated circuits (PICs) have been investigated vigorously due to their exceptional advantages such as high speed, high sensitivity, high-density integration, low cost, compactness, and robustness against the environmental fluctuation by eliminating the assembly and alignment of the free-space optical components. Especially, near- and mid-infrared photonics have intrigued a great interest in various sensing applications including the physical object/environment imaging and mapping, material identification, and chemical/biomolecule sensing due to the strong fundamental vibrational-rotational signatures of the distinct chemical bonds and high transmittance in an ambient atmospheric environment or in-vivo mammalian bio-cells. The basic components constituting the PICs are the micro/nano waveguides to guide the light by the total internal reflection, and the most matured PIC material platforms are typically based on silicon platforms. However, depending on the targeting application's operation scheme and wavelengths, appropriate material platforms and structures should be designed and optimized to minimize material loss and maximize performance. This Ph.D. dissertation focuses on the design, fabrication, and experimental characterization of the various passive photonic components in different material platforms and photonic integrated sensor devices for the mid-infrared (MIR) absorption trace gas sensors, near-infrared (NIR) on-chip spectrometers, and biosensing applications. The first chapter covers the MIR trace gas sensor devices based on the suspended InGaAs membrane waveguides. We designed and compared two different waveguide structures on the III-V material platform considering the monolithic integration of the sensing waveguides with the light sources and detectors in MIR wavelengths. The second chapter demonstrates the NIR spatial heterodyne Fourier transform spectrometer (SHFTS) integrated with a subwavelength grating coupler (SWGC) for the dual-polarization bandpass sampling on the Si3N4 platform to solve the intrinsic trade-off limitation between the resolution and bandwidth. After that, the micro-ring resonator (MRR) biosensor devices integrated with SHFTS for the lab-on-a-chip optical biosensor platform on the silicon-on-insulator wafer were presented which can substitute the external optical spectrum analyzers for detecting the resonance wavelength shift. Finally, a thorough study on the point-of-care SARS-CoV-2 lab-on-a-chip (LoC) optical biosensor platforms is presented, and the recommendations for future research will be discussed.

description: A complete and simple invariant classification of the conformally flat pure radiation metrics with a negative cosmological constant that were obtained by integration using the generalised invariant formalism is presented. We show equivalence between these metrics and the corresponding type O subclass of the more general spacetime studied by Siklos. The classification procedure indicates that the metrics possess a one degree of null isotropy freedom which has very interesting repercussions in the symmetry analysis. The Killing and homothetic vector analysis in GHP formalism is then generalised to this case were there is only one null direction defined geometrically. We determine the existing Killing vectors for the different subclasses that arise in the classification and compare these results to those obtained in the symmetry analysis performed by Siklos for a larger class of metrics with Ricci tensor representing a pure radiation field and a negative cosmological constant. It is also shown that there are no homothetic Killing vectors present.

description: Maya Kaqchikel women theater groups in Guatemala emerged in the 2000s in collaboration with Mestiza/o directors to denounce the multiple forms of violence they have historically experienced while simultaneously advocating for personal and collective healing. Drawing from eleven in-depth interviews with Maya Kaqchikel theater-making artists and Mestiza/o directors of two theater groups, this dissertation explores how these women engaging in the theater-making process disrupts colonial scripts of patriarchal violence by performing healing as a form of resistance. In particular, this study analyzes the theater-making process as a healing system rooted in Maya women’s ancestral knowledge of traditional medicine embedded in the transformational power of their performances. The three main stages of performing healing identified in this dissertation are: (a) acknowledging the wound(s), (b) personal experiences of transformation, and (c) remedies as cultural knowledge promoting healing. Based on ethnographic work in Guatemala from June 2019 to June 2020 and performance theory, I suggest that Maya Kaqchikel women's theater groups disrupt colonial legacies of racial, gender, sexual, and class stratification in Guatemala by performing healing as resistance. They overtly disrupt what I call colonial scripts of rapeability. These cultural scripts are rooted in colonial narratives promoting the historical repetition of events, discourses, and images that have survived the test of time, complex legacies of all forms of violence against Indigenous and Mestiza women. Such forms of violence may go from its most normalized and socially accepted expressions, to its most extreme and brutal, including but not limited to femicide. These complex expressions of violence against women living in colonized territories take place in the context of interpersonal relationships and everyday life. These forms of violence against women are often left in impunity, causing its normalization and repetition. Within this context, healing as resistance is not only an individual experience, but rather it becomes a collective expression of resilience and resistance rooted in Maya women's ancestral forms of knowledge.

description: Aims. The interaction of supernova remnants (SNRs) with molecular clouds gives rise to strong molecular emission in the far-IR and sub-mm wavelength regimes. The application of MHD shock models in the interpretation of this line emission can yield valuable information on the energetic and chemical impact of supernova remnants. Methods. New mapping observations with the APEX telescope in CO (3-2), (4-3), (6-5), (7-6) and 13CO (3-2) towards two regions in the supernova remnant W44 are presented. Integrated intensities are extracted on five different positions, corresponding to local maxima of CO emission. The integrated intensities are compared to the outputs of a grid of models, which combine an MHD shock code with a radiative transfer module based on the large velocity gradient approximation. Results. All extracted spectra show ambient and line-of-sight components as well as blue- and red-shifted wings indicating the presence of shocked gas. Basing the shock model fits only on the highest-lying transitions that unambiguously trace the shock-heated gas, we find that the observed CO line emission is compatible with non-stationary shocks and a pre-shock density of 10^4 cm-3. The ages of the modelled shocks scatter between values of \sim1000 and \sim3000 years. The shock velocities in W44F are found to lie between 20 and 25 km/s, while in W44E fast shocks (30-35 km/s) as well as slower shocks (\sim20 km/s) are compatible with the observed spectral line energy diagrams. The pre-shock magnetic field strength components perpendicular to the line of sight in both regions have values between 100 and 200 \muG. Our best-fitting models allow us to predict the full ladder of CO transitions, the shocked gas mass in one beam as well as the momentum- and energy injection.

description: The concept of local e-Government has become a key factor for delivering services in an efficient, cost effective, transparent and convenient way, in circumstances where a) citizens do not have enough time available to communicate with local authorities in order to perform their responsibilities and needs, and b) information and communication technologies significantly facilitate administrative procedures and citizens-government interaction. This paper aims to identify e-services that local authorities provide, and to investigate their readiness for delivering these services. A pilot research has been conducted to identify the offer of e-services by local authorities, along with e-readiness in municipalities of the Pelagonia region in the Republic of Macedonia. The survey was carried out by means of structured interview questions based on a modified model proposed by Partnership on Measuring ICT for Development - web analysis of municipal websites in the region has been conducted, as well. The study reveals uneven distribution according to the age group of users, lack of reliability and confidence for processing the needs and requests electronically by a large part of the population, and improperly developed set of ICT tools by local governments for providing a variety of services that can be fully processed electronically.

description: Electronic structure of zinc blende AlN(1-x)$Px alloy has been calculated from first principles. Structural optimisation has been performed within the framework of LDA and the band-gaps calculated with the modified Becke-Jonson (MBJLDA) method. Two approaches have been examined: the virtual crystal approximation (VCA) and the supercell-based calculations (SC). The composition dependence of the lattice parameter obtained from the SC obeys Vegard's law whereas the volume optimisation in the VCA leads to an anomalous bowing of the lattice constant. A strong correlation between the band-gaps and the structural parameter in the VCA method has been observed. On the other hand, in the SC method the supercell size and atoms arrangement (clustered vs. uniform) appear to have a great influence on the computed band-gaps. In particular, an anomalously big band-gap bowing has been found in the case of a clustered configuration with relaxed geometry. Based on the performed tests and obtained results some general features of MBJLDA are discussed and its performance for similar systems predicted.

description: The cultural ecosystem services of urban parks contribute to the urban population’s urban experience and well-being. Urban greenspaces such as urban parks are under extreme pressure from rapid urbanization and changing climate condition. During the pandemic understanding on the importance of cultural ecosystem services was lacking. Little evidence is known about how people use and value the urban parks during the COVID-19 pandemic. In this study, urban park users were interviewed and observed to address the aim of this research which is to understand what cultural ecosystem services people value in urban parks during the pandemic and what spatial features were important in their experience. Using semi-structured on-site interviews and activity-based observation of users and activities in two Metro Manila urban parks, several bundles of cultural ecosystem services emerge. Aesthetics, recreation and spiritual values were the most identified cultural ecosystem service by urban park users. The urban parks during the pandemic served as a place for refuge and connecting with nature. The green and grey dimensions of the park provided multiple values for people encompassing a range of cultural ecosystem services. The methods that were used in this research allowed for a simple and comprehensive assessment of the value of the urban parks. This provided an alternative way to help inform park administrators and planners in understanding and managing important urban green spaces and their cultural ecosystem service benefits.

description: Over the past decade, the Secret Lives of Cepheids (SLiC) program has been carried out at Villanova University to study aspects and behaviors of classical Cepheids that are still not well-understood. In this, the first of several planned papers on program Cepheids, we report the current results for delta Cep, the Cepheid prototype. Ongoing photometry has been obtained to search for changes in the pulsation period, light curve morphology and amplitude. Combining our photometry with the times of maximum light compilation by Berdnikov 2000 returns a small period change of dP/dt ~ -0.1006 +/- 0.0002 sec yr^-1. There is also evidence for a gradual light amplitude increase of ~0.011-mag (V-band) and ~0.012-mag (B-band) per decade over the last ~50 years. In addition, HST-COS UV spectrophotometry and XMM-Newton X-ray data were carried out to investigate the high-temperature plasmas present above the Cepheid photospheres. In total, from the five visits (eight exposures) with XMM-Newton, delta Cep is found to be a soft X-ray source (Lx [0.3--2 keV] ~ 4.5-13x10^28 erg sec^-1) with peak flux at kT = 0.6-0.9 keV. The X-ray activity is found to vary, possibly in phase with the stellar pulsations. From 2010-2013, nine observations of delta Cep were carried out with HST-COS. The UV emissions are also variable, and well-phased with the stellar pulsations. Maximum UV line emissions occur near, or slightly before, maximum optical light, varying by as much as twenty times. This variability shows that pulsation-induced shock-heating plays a significant role in Cepheid atmospheres, possibly in addition to a quiescent, magnetic heating. The results of this study show Cepheid atmospheres to be rather complex and dynamic.

description: As globalization and interstate commerce continue to permeate the US economy, the opportunities for growth and development for businesses among a variety of sectors have likewise expanded notably over the last two decades. One state that has especially drawn attention as of late for its economic potence is Virginia, partly on account of its proximity to Washington, DC, as well as the nationwide shift toward technologically-oriented jobs. Our data can be found at the Bureau of Economic Analysis, and downloaded and converted as CSV files with the help of Pandas. After cleaning up our data to focus on the years 2001 through 2018, we will first look at trends in personal and per capita income in both absolute and relative figures. Similarly, we will pivot toward population, and isolate the areas with the most significant absolute and relative shifts in this regard. Finally, we will expand our inquiry toward identifying which areas contributed the most in terms of GDP and share of GDP for a given industry. As an extension to this last point, we will also determine the most significant sectors for a given area, and based on their share values evaluate whether or not that area reported a diversified economy, or relied disproportionately on one particular sector. With this in mind, we can deduce if there are any industries drawing more people toward certain areas. The ind_gdp and pop_inc data sets used for this project are available for you to view and save for later.

description: Data for a Journal article titled 'Male Mediterranean fruit flies prefer warmer temperatures that improve sexual performance' published on Journal of Thermal Biology, Volume 108, August 2022, 103298. The dataset contains R scripts and digital data on the thermal preference of virgin and sexually mature Mediterranean fruit flies (Ceratitis capitata), that test the idea of sex-related variation in thermal preference results from different reproductive benefits for each sex. Three specific hypotheses were tested: Hypothesis 1. Sexually mature, virgin male C. capitata prefer higher temperatures to facilitate increased calling behaviour
 Hypothesis 2. Sexually mature, virgin male C. capitata prefer higher temperatures to facilitate sexual performance Hypothesis 3. Female C. capitata prefer lower temperatures to improve reproductive output through more efficient conversion of food to eggs. R scripts used to analyse the accompanying data files are: Gradients.R: Gradients.csv; Temp_VP.csv; Temp_Evaporation.csv Thermal pref_male performance.R: Preference_data.csv; Male_calling.csv; Mating.csv Thermal pref female performance.R: Survival.csv; Eggs_cumulative.csv; Eggs_total.csv; Female_consumption.csv

description: In strongly correlated electronic systems, such as manganites, the global transport behavior depends sensitively on the spin ordering, whose alteration often requires a large external magnetic field. Here we show that the spin ordering in manganites can be easily controlled by exchange field across the interface between a ferromagnet and a manganite. By depositing isolated ferromagnetic nanodots on a manganite thin film, we find that it is possible to overcome dimensionality and strain effects to raise the metal-insulator transition (MIT) temperature by over 200 K and increase the magnetoresistance by 5000%. The MIT temperature can also be tuned by controlling the density of the magnetic nanodots which indicates that the formation process of electronic phase separation can be controlled by the presence of magnetic nanodots.

description: We use color-magnitude diagram synthesis together with theoretical relations from non-linear pulsation models to approach the long-standing problem of the Oosterhoff dichotomy related to the distribution of the mean periods of fundamental RR Lyrae variables in globular clusters. By adopting the chemical composition determined from spectroscopic observations and a criterion to account for the hysteresis mechanism, we tuned age and mass-loss to simultaneously reproduce the morphology of both the turn-off and the Horizontal Branch of a sample of 17 globular clusters of the Milky Way and of nearby dwarf galaxies in the crucial metallicity range (-1.9

description: A state-based micropolar peridynamic theory for linear elastic solids is proposed. The main motivation is to introduce additional micro-rotational degrees of freedom to each material point and thus naturally bring in the physically relevant material length scale parameters into peridynamics. Non-ordinary type modeling via constitutive correspondence is adopted here to define the micropolar peridynamic material. Along with a general three dimensional model, homogenized one dimensional Timoshenko type beam models for both the proposed micropolar and the standard non-polar peridynamic variants are derived. The efficacy of the proposed models in analyzing continua with length scale effects is established via numerical simulations of a few beam and plane-stress problems.
Dark matter direct detection constraints from gauge bosons loops

description: While many interactions of dark matter (DM) with the standard model (SM) affect direct detection and LHC searches, there are only a few operators generating annihilation of DM into photons. All of these operators, except four of them, give rise to unsuppressed rates, rendering indirect detection superior to other search strategies. For two of the four effective interactions with velocity-suppressed annihilation cross sections, we identify a new type of loop effect which significantly enhances the associated direct detection rates. As a result, relevant constraints from next-generation direct detection experiments on DM-SM interactions, so far only bounded by the LHC, are obtained.
