description: We introduce \emph{ScalableMax}, a novel communication scheme for achieving max-consensus in a network of multiple agents which harnesses the interference in the wireless channel as well as its multicast capabilities. In a sufficiently dense network, the amount of communication resources required grows logarithmically with the number of nodes, while in state-of-the-art approaches, this growth is at least linear. ScalableMax can handle additive noise and works well in a high SNR regime. For medium and low SNR, we propose the \emph{ScalableMax-EC} scheme, which extends the ideas of ScalableMax by introducing a novel error correction scheme. It achieves lower error rates at the cost of using more channel resources. However, it preserves the logarithmic growth with the number of agents in the system.

description: This paper is concerned with certain connections between the ensemble of n x n unitary matrices -- specifically the characteristic function of the random variable tr(U) -- and combinatorics -- specifically Ulam's problem concerning the distribution of the length of the longest increasing subsequence in permutation groups -- and the appearance of Painleve functions in the answers to apparently unrelated questions. Among the results is a representation in terms of a Painleve V function for the characteristic function of tr(U) and (using recent results of Baik, Deift and Johansson) an expression in terms of a Painleve II function for the limiting distribution of the length of the longest increasing subsequence in the hyperoctahedral group.

description: This dissertation examines issues of social class and musical parenting within the context of an early childhood jazz education program. Using administrative and survey data from 469 self-selected families from six cities in the U.S. where this program is offered, I aimed to identify what factors play a role in parental decisions for enrolling in the program and whether those factors were associated with their social class. Considering this early childhood jazz program as an organized activity supports the analysis of music classes as a form of investment in cultural capital fostered by parents.  I used current economic models of the family and theories of social and cultural class reproduction to understand families’ participation in the program and their musical engagement.
      Principal component analysis revealed four components representing possible reasons that drove parents to enroll in the program: Cultural and Educational Enrichment for the Future; Appreciation of Jazz; Socialization and Bonding; and Social Networks. Simple linear regression analysis showed significant associations between socioeconomic status (SES) and two principal components (Cultural and Educational Enrichment for the Future and Social Networks).
      Overall, parents showed high scores of both general and musical engagement, and those variables were highly correlated.  Additionally, there were no statistically significant associations between parents’ previous formal musical experiences and their musical engagement when controlling for musical materials at home and their average value of music education.  Parents’ engagement with the program activities was positively associated with their music making at home and that association stayed stable and strong after taking into account sociodemographic factors, parents’ values of music education and access to musical materials.
      Families from lower SES backgrounds used activities and materials from the jazz class at home with more frequency than families from other SES groups. This finding could suggest that when lower SES families are given access, they incorporate new musical tools and ideas from the jazz program as affordances to increase their parenting skills; therefore, the impact of the program might be stronger for those parents than for the other more advantaged groups. Jazz music in this context seems to be working as an equalizer of opportunities by reducing inequalities.
Musical Sound and Spatial Perception: How Music Structures Our Sense of Space

description: It is not uncommon to read claims of music’s ability to affect our sense of time and its rate of passage. Indeed, such effects are often considered among the most distinctive and prized aspects of musical aesthetics. Yet when it comes to the similarly abstract notion of space and its manipulation by musical structures, theorists are generally silent. My dissertation addresses this gap in the literature and shows how music’s spatial effects arise through an affective engagement with musical works. In this study, I examine an eclectic selection of compositions to determine how the spaces we inhabit are transformed by the music we hear within them. Drawing on Maurice Merleau-Ponty’s theory of embodied perception, as well as research on acoustics, sound studies, and media theory, I deploy an affective model of spatial perception—a model that links the sense of space with the moment-to-moment needs and desires of the perceiver— to explain how these musical modulations of space occur. My claim is that the manner in which the music solicits our engagement affects how we respond, which in turn affects what we perceive. I begin by discussing the development of recording technology and how fixed media works deemed “spatial music” reinforce a particular conception of space as an empty container in which sound sources are arrayed in specific locations relative to a fixed listening position. After showing how innovative studio techniques have been used to unsettle this conventional spatial configuration, I then discuss examples of Renaissance vocal music, instrumental chamber music, and 20th century electronic music in order to develop a richer understanding of the range of spatial interactions that musical textures and timbres can provide. In my final chapter, I draw upon these varieties of affective engagement to construct a hermeneutic analysis of the spatial experience afforded by Steve Reich’s Electric Counterpoint, thereby modeling a phenomenological method for grounding interpretation in embodied, rather than strictly discursive, practices. By soliciting movement through the call for bodily action, music allows us an opportunity to fit together one world of possibilities with another, thereby providing an occasion for grasping new meanings presented through the work. The spatial aspect of music, therefore, does not consist in merely recognizing an environmental setting populated by individual sound sources. Through the embodied practices of music perception and the malleability of space they reveal, we are afforded an opportunity to reshape our understanding of the world around us.
The Martin-Benito-Mena Marugan-Olmedo prescription for the Dapor-Liegener model of Loop Quantum Cosmology

description: Recently, an alternative Hamiltonian constraint for Loop Quantum Cosmology has been put forward by Dapor and Liegener, inspired by previous work on regularization due to Thiemann. Here, we quantize this Hamiltonian following a prescription for cosmology proposed by Mart\'ın-Benito, Mena Marugán, and Olmedo. To this effect, we first regularize the Euclidean and Lorentzian parts of the Hamiltonian constraint separately in the case of a Bianchi I cosmology. This allows us to identify a natural symmetrization of the Hamiltonian which is apparent in anisotropic scenarios. Preserving this symmetrization in isotropic regimes, we then determine the Hamiltonian constraint corresponding to a Friedmann-Lemaître-Robertson-Walker cosmology, which we proceed to quantize. We compute the action of this Hamiltonian operator in the volume eigenbasis and show that it takes the form of a fourth-order difference equation, unlike in standard Loop Quantum Cosmology, where it is known to be of second order. We investigate the superselection sectors of our constraint operator, proving that they are semilattices supported only on either the positive or the negative semiaxis, depending on the triad orientation. Remarkably, the decoupling between semiaxes allows us to write a closed expression for the generalized eigenfunctions of the geometric part of the constraint. This expression is totally determined by the values at the two points of the semilattice that are closest to the origin, namely the two contributions with smallest eigenvolume. This is in clear contrast with the situation found for the standard Hamiltonian of Loop Quantum Cosmology, where only the smallest value is free. This result indicates that the degeneracy of the new geometric Hamiltonian operator is equal to two, doubling the possible number of solutions with respect to the conventional quantization considered until now.

description: The integration of Muslims into the European society is one of the most critical issues facing Europe today. The way this process evolves will determine the direction, development and stability of the entire Continent. The issue preoccupies both the scholarly community, politics and the popular culture. With a media not immune to prejudicial attitudes about Muslims in Europe, the Continent has plunged into an atmosphere of tension and is fraught with a sense of deep insecurity. The atrocious terrorist attacks perpetrated there by Islamic terrorists and even those simply of Muslim heritage casts a heavy suspicion on Europe’s entire Muslim minority, exacerbating their situation and projecting a disquieting future for Europe. This paper examines the way various sources of information address the issue of Muslims in Europe in order to asses as accurately as possible their real situation. It elaborates on the multifaceted aspects of Muslim integration, focusing on the community’s heterogeneity, religious and ethnic identity and its relations with the state. The paper also builds on the most recent available statistical data and surveys to provide a more realistic evaluation of the wellbeing of Muslims in Europe. The paper also explores the complexity of the issue of religiosity and secularity and the role of Muslims in the rethinking and defining the boundaries of a European public space. Finally, a comparative analysis between the French and British approach to Muslim integration is made which delineates their differences and commonalities and the way the integration policies of these two major countries hosting the biggest Muslim minorities in Europe influence the situation of Muslims today.

description: Recent experiments by Kudrolli, Pier and Gollub on surface waves, parametrically excited by two-frequency forcing, show a transition from a small hexagonal standing wave pattern to a triangular ``superlattice'' pattern. We show that generically the hexagons and the superlattice wave patterns bifurcate simultaneously from the flat surface state as the forcing amplitude is increased, and that the experimentally-observed transition can be described by considering a low-dimensional bifurcation problem. A number of predictions come out of this general analysis.

In order to treat the nonequilibrium distribution self-consistently the full two-time structure of the theory is employed without relying on any sort of Kadanoff-Baym Ansatz. The results are independent of the choice of the electromagnetic field if the variation of the self-energy is taken into account. Excellent quantitative agreement is obtained with the experimental gain spectrum of a quantum cascade laser. Calculations for semiconductor superlattices show that the simple 2-time miniband transport model gives reliable results for large miniband widths at room temperature

description: Importance: Hearing loss appears to have adverse effects on cognition and increases risk for cognitive impairment. These associations have not been thoroughly investigated in the Hispanic and Latino population, which faces hearing health disparities.
Objective: To examine associations between hearing loss with 7-year cognitive change and mild cognitive impairment (MCI) prevalence among a diverse cohort of Hispanic/Latino adults.
Design, Setting, and Participants: This cohort study used data from a large community health survey of Hispanic Latino adults in 4 major US cities. Eligible participants were aged 50 years or older at their second visit to study field centers. Cognitive data were collected at visit 1 and visit 2, an average of 7 years later. Data were last analyzed between September 2023 and January 2024.
Exposure: Hearing loss at visit 1 was defined as a pure-tone average (500, 1000, 2000, and 4000 Hz) greater than 25 dB hearing loss in the better ear.
Main outcomes and measures: Cognitive data were collected at visit 1 and visit 2, an average of 7 years later and included measures of episodic learning and memory (the Brief-Spanish English Verbal Learning Test Sum of Trials and Delayed Recall), verbal fluency (word fluency-phonemic fluency), executive functioning (Trails Making Test-Trail B), and processing speed (Digit-Symbol Substitution, Trails Making Test-Trail A). MCI at visit 2 was defined using the National Institute on Aging-Alzheimer Association criteria.
Results: A total of 6113 Hispanic Latino adults were included (mean [SD] age, 56.4 [8.1] years; 3919 women [64.1%]). Hearing loss at visit 1 was associated with worse cognitive performance at 7-year follow-up (global cognition: β = -0.11 [95% CI, -0.18 to -0.05]), equivalent to 4.6 years of aging and greater adverse change (slowing) in processing speed (β = -0.12 [95% CI, -0.23 to -0.003]) equivalent to 5.4 years of cognitive change due to aging. There were no associations with MCI.
Conclusions and relevance: The findings of this cohort study suggest that hearing loss decreases cognitive performance and increases rate of adverse change in processing speed. These findings underscore the need to prevent, assess, and treat hearing loss in the Hispanic and Latino community.
My Body, My Instrument: How body image influences vocal performance in collegiate women singers

Body image in women
Women college students

description: This dissertation is about the influence of body image on classical vocal performance in collegiate women singers. Those trained in classical singing are familiar with the phrase, “your body is your instrument.” A focus on the physical body is apparent in the vocal pedagogical literature, as is attention to singers’ mental and emotional states. But the intersection of emotions and the body—how one thinks and feels about their body, or body image—is largely absent from the vocal pedagogical literature. As voice teachers continue to necessarily address their students’ instruments (bodies), the field has not adequately considered how each singer’s relationship with their instrument (their body) might affect them, as singers and as people. This initial foray sought answers to just two of the myriad unanswered questions surrounding this topic: Does a singer’s body image influence her singing? If so, when and how? It employed a feminist methodological framework that would provide for consciousness-raising as both a method and aim of the study. Four collegiate women singers served as co-researchers, and data collection took place in three parts: a focus group, audio diaries, and interviews. The focus group was specifically geared towards consciousness-raising in order to provide co-researchers with the awareness necessary for examining their body image. Co-researchers then recorded semi-structured audio diaries for one month after practice sessions, voice lessons, and performances. One-on-one interviews concluded data collection and provided a situation of co-analysis wherein the researcher and co-researcher could deeply examine data from the focus group and diaries. The major discovery of this research is a pervasive sense of separation between a woman singer’s “everyday body” and her singer’s body. Self-objectification served as a barrier to a conscious recognition of embodied experience and effectively split the singer in two. The various states of the relationship between these two seemingly separate entities resulted in specific outcomes for singing, including restriction, unawareness, inconsistency, and focus. The discussion concludes with a consideration of how a positive body image may encourage effective and artistic vocal performance and how voice teachers might help foster a positive experience of one’s body.

description: Highly accurate variational calculations, based on a few-parameter, physically adequate trial function, are carried out for the hydrogen molecule \hh in inclined configuration, where the molecular axis forms an angle $θ$ with respect to the direction of a uniform constant magnetic field ${\bf B}$, for $B=0,\, 0.1,\, 0.175$ and $0.2\,$a.u. Three inclinations $θ=0^\circ,\,45^\circ,\,90^\circ$ are studied in detail with emphasis to the ground state $1_g$. Diamagnetic and paramagnetic susceptibilities are calculated (for $θ=45^\circ$ for the first time), they are in agreement with the experimental data and with other calculations. For $B=0,\, 0.1$ and $0.2\,$a.u. potential energy curves $E$ vs $R$ are built for each inclination, they are interpolated by simple, two-point Padé approximant $Pade[2/6](R)$ with accuracy of not less than 4 significant digits. Spectra of rovibrational states are calculated for the first time. It was found that the optimal configuration of the ground state for $B \leq B_{cr}=0.178\,$a.u. corresponds always to the parallel configuration, $θ=0$, thus, it is a $^1Σ_g$ state. The state $1_g$ remains bound for any magnetic field, becoming metastable for $B > B_{cr}$, while for $B_{cr} < B < 12$\,a.u. the ground state corresponds to two isolated hydrogen atoms with parallel spins.

description: We obtain an Einstein metric of constant negative curvature given an arbitrary boundary metric in three dimensions, and a conformally flat one given an arbitrary conformally flat boundary metric in other dimensions. In order to compute the on-shell value of the gravitational action for these solutions, we propose to integrate the radial coordinate from the boundary till a critical value where the bulk volume element vanishes. The result, which is a functional of the boundary metric, provides a sector of the quantum effective action common to all conformal field theories that have a gravitational description. We verify that the so-defined boundary effective action is conformally invariant in odd (boundary) dimensions and has the correct conformal anomaly in even (boundary) dimensions. In three dimensions and for arbitrary static boundary metric the bulk metric takes a rather simple form. We explicitly carry out the computation of the corresponding effective action and find that it equals the non-local Polyakov action.

description: Teck Cominco Limited and its subsidiaries and associated companies are a diversified mining, smelting and refining group headquartered in Vancouver, British Columbia. Teck Cominco holds interests in producing mines in Canada, the United States and Peru, mining zinc, copper, lead, gold and metallurgical coal from both open-pit and underground operations. In February 2003 Teck Cominco’s Board adopted its Charter of Corporate Responsibility and the Code of Business, Environmental and Health and Safety Practices. The Charter states “ We support sustainable development and we willingly accept our obligations to constantly improve our methods of harvesting the world’s resources to the benefit of our shareholders, employees, customers and local communities and all others who use or enjoy nature’s bounty”. Based on these overarching commitments, early in 2003 the company also instituted a comprehensive EHS Management System through a set of management standards. Examples of three case studies from our Kimberly Operations (British Columbia), Red Dog Mine (Alaska) and the Pend Oreille Mine (Washington) will illustrate how these commitments are contributing to the development of sustainable communities in North America.

description: A central problem of neuroscience involves uncovering the principles governing the organization of nervous systems which ensure robustness in brain development. The nematode Caenorhabditis elegans provides us with a model organism for studying this question. In this paper, we focus on the invariant connection structure and spatial arrangement of the neurons comprising the somatic neuronal network of this organism to understand the key developmental constraints underlying its design. We observe that neurons with certain shared characteristics - such as, neural process lengths, birth time cohort, lineage and bilateral symmetry - exhibit a preference for connecting to each other. Recognizing the existence of such homophily helps in connecting the physical location and morphology of neurons with the topological organization of the network. Further, the functional identities of neurons appear to dictate the temporal hierarchy of their appearance during the course of development. Providing crucial insights into principles that may be common across many organisms, our study shows how the trajectory in the developmental landscape constrains the eventual spatial and network topological organization of a nervous system.

description: We report experiments on convection driven by a radial electrical force in suspended annular smectic A liquid crystal films. In the absence of an externally imposed azimuthal shear, a stationary one-dimensional (1D) pattern consisting of symmetric vortex pairs is formed via a supercritical transition at the onset of convection. Shearing reduces the symmetries of the base state and produces a traveling 1D pattern whose basic periodic unit is a pair of asymmetric vortices. For a sufficiently large shear, the primary bifurcation changes from supercritical to subcritical. We describe measurements of the resulting hysteresis as a function of the shear at radius ratio $η\sim 0.8$. This simple pattern forming system has an unusual combination of symmetries and control parameters and should be amenable to quantitative theoretical analysis.

description: Abstract The gut microbiome plays a crucial role in the health and well-being of animals. It is especially critical for ruminants that depend on this bacterial community for digesting their food. In this study, we investigated the effects of management conditions and supplemental feeding on the gut bacterial microbiota of red deer ( Cervus elaphus ) in the Bavarian Forest National Park, Germany. Fecal samples were collected from free-ranging deer, deer within winter enclosures, and deer in permanent enclosures. The samples were analyzed by high-throughput sequencing of the 16 S rRNA gene. The results showed that the gut bacterial microbiota differed in diversity, abundance, and heterogeneity within and between the various management groups. Free-ranging deer exhibited lower alpha diversity compared with deer in enclosures, probably because of the food supplementation available to the animals within the enclosures. Free-living individuals also showed the highest beta diversity, indicating greater variability in foraging grounds and plant species selection. Moreover, free-ranging deer had the lowest abundance of potentially pathogenic bacterial taxa, suggesting a healthier gut microbiome. Winter-gated deer, which spent some time in enclosures, exhibited intermediate characteristics between free-ranging and all-year-gated deer. These findings suggest that the winter enclosure management strategy, including supplementary feeding with processed plants and crops, has a significant impact on the gut microbiome composition of red deer. Overall, this study provides important insights into the effects of management conditions, particularly winter enclosure practices, on the gut microbiome of red deer. Understanding these effects is crucial for assessing the potential health implications of management strategies and highlights the value of microbiota investigations as health marker. © In Copyright http://rightsstatements.org/vocab/InC/1.0/

description: High temperature superconductivity in doped Mott insulators such as the cuprates contradicts the conventional wisdom that electron repulsion is detrimental to superconductivity. Because doped fullerene conductors are also strongly correlated, the recent discovery of high-critical-temperature, presumably s-wave, superconductivity in C$_{60}$ field effect devices is even more puzzling. We examine a dynamical-mean-field solution of a model for electron doped fullerenes which shows how strong correlations can indeed enhance superconductivity close to the Mott transition. We argue that the mechanism responsible for this enhancement could be common to a wider class of strongly correlated models, including those for cuprate superconductors.

description: We further develop the finite length path generating transforms introduced previously, and use them to obtain constant sign polynomial expressions that reduce, in the limit of infinite path lengths, to parafermion and ABF Virasoro characters. This provides us, in the ABF case, with combinatorial proofs of Melzer's boson-fermion polynomial identities.

Using mobilage thinking to study healthcare students’ experiences of using and learning to use mobile phones for academic work
Creators: name: Johnson, Mike
Publisher: name: Lancaster University
Year: 2019

description: This thesis adopts a realist ontology, hermenutic epistemology and phenomonological methodology to ask, 'What is learning at university like for healthcare students in a mobile assemblage (mobilage)?'. ‘Mobilage’ blends ideas from Actor Network Theory and educational theory to provide a wholistic unit of analysis, student-with-a-smartphone, rather than splitting subject/object or fixating on the human or a technology. The study launched with an online survey which gathered background information and advertised an online focus group (OFG) and exploratory meetings, ‘mobilage encounters’. The OFG ran with 7 informants over 3 months and there were 10 encounters. Data from these were combined with autobiographical insights in a narrowing interpretive focus on mobilage. The OFG sought to avoid intrusive informant observation while enabling participation from anywhere, especially within mobilage. Weekly trigger messages were sent through Microsoft’s Yammer platform, akin to experience sampling/cultural probe methods, yet with the potential for shared responses. Consensus formed around several themes, including the challenges and artfulness of mobile phone-based work. Encounter data was gathered and used to re-play the encounter into my consciousness, often while walking secluded coastal pathways. These experiences were combined with the data corpus to help create ten phenomenological vignettes, with the goal of re-presencing readers. A discussion section accompanies all but one of the vignettes. Mobilage is a site of struggle for deliberation and phronesis due to the multiple virtual and actual lines and layers of connectivity between psyche and the life-world. The thesis concludes noting the incursion of technology and economic/pragmatic meta-discourses into academic work. In the face of these challenges, higher education stakeholders must assert the importance of scholarly values and humanistic goals (such as Bildung (Gadamer, 1992)) which students are doing to some extent.
Biological removal of arsenic in a multi-stage engineered wetlands : treating a suite of heavy metals

description: A biological engineered wetlands treatment system designed to treat high concentrations of heavy metals built for Teck Cominco in Trail, BC has treated leachate since 1998. Leachate is collected from an historical landfill (now capped) and arsenic storage areas. Metal loadings have averaged more than 350 ppm Zn, 85 ppm As and 5 ppm Cd with peaks of 790 ppm Zn, 355 ppm As and 25 ppm Cd. Total volume of water treated is more than 11 million liters. The system has consistently removed As, reducing the initially high concentrations to 0.5 ppm or lower year round. During periods of extensive changes and reconstruction the operating characteristics of the system changes and As removal efficiency drops demonstrating the importance of maintaining a consistent environment for the bacteria responsible for As removal. A pilot-scale arsenic research project has been constructed in Trail. As well as the field program a multifaceted research project has been developed to examine the removal process under controlled laboratory conditions at the Royal Military College in Kingston, Ontario (As speciation) and at CANMET research facilities in Ottawa, Ontario (microbiological studies). Preliminary results from this research program are presented.
A Further Survey of Stamped Tiles of the Classis Britannica

description: Roman tile bearing a stamp formed of the letters CL BR (Classis Britannica) has been found on several coastal sites in south-east Britain; it has also been found at Boulogne, which was at one time the headquarters of the British fleet. The finding of similar stamps on tile at several iron-working sites in East Sussex has shown that the navy was also involved with the production of iron. These stamps have a wide range of form and style, varying from the elegant to the crude. The practice of CL BR stamping seems to date from the early second century to the mid-third century, but it is difficult to establish precise dates. Nearly 100 different forms of CL BR stamps have been discovered in Britain, and there is evidence of British-made tile being found in France, and vice-versa. Evidence of grain-marking suggests that the dies were made of wood, but dies made of baked-clay or metal are a possibility. The Legions likewise produced stamped tile with a great variety of stamps, and the whole purpose of stamping seems to have been to establish an authority and to safeguard against the misuse of official tile. These stamped tiles provide much information about the production and procedure of tile-marking since, apart from the stamps the tile, also often carry the tile-marker's personal mark as well as tally-marks, probably numerals, cut on the edge. This paper is a survey of over 1500 examples of CL BR stamps with a full analysis of their types and characteristics.

description: Historically, the role of immune cells in the nervous system was predominantly examined throughthe lens of disease. In recent years, studies have shown that the complex, orchestrated events of immune activity throughout embryonic and postnatal critical periods are crucial for proper nervous system development. While previous studies have suggested limited immune heterogeneity in the adult brain, the diverse roles of the hippocampus in cognition and pathological development would suggest variation of immune cells in this region. Specifically, the hippocampus is known to be a site of adult neurogenesis. However, fundamental traits of immune cells in this region have not been well characterized. In chapter one, I present a summary of literature that discusses what was previously known of immune regulation of adult neurogenesis during health and disease. In chapter two, I compare different reporter lines and marker genes to evaluate responses in various cell types in the neurogenic niche and in other regions of the brain in the context of injury and pharmacological modulation. I discuss preliminary evidence suggesting microglial depletion may result in phenotypic changes in astrocytes throughout the hippocampus. In chapter three, I provide evidence of heterogeneity in myeloid-lineage cells in the hippocampus. I leveraged the highthroughput nature of cell suspension based single cell RNA-sequencing to collect transcriptomes of over 20,000 myeloid lineage cells from murine hippocampi. Using a series of bioinformatic techniques, I was able to computationally dissect different populations within this system and found spatial mapping of one distinct subset specifically localized to the neurogenic niche of the hippocampus. The transcriptomic signature of these cells alongside immunoreactivity to candidate genes, and morphological properties of this population resemble those of reactive microglia associated with the restriction of neurodegenerative diseases. In chapter four, I discuss how the immune landscape of the hippocampus responds to perturbation using a model of Focused Ultrasound mediated Blood-Brain Barrier opening. Subtypes of myeloid lineage cells change in composition and in transcriptomic response. We find distinct, temporally defined transcriptional responses in microglial and macrophage populations, indicating discrete roles for microglia and macrophages in immune activity during the transition from acute to chronic response. Together, these findings point towards diverse properties of microglia in the adult hippocampus.
