kooperativer Unterricht

description: Schulische Heilpädagoginnen und Heilpädagogen die in Regelklassen arbeiten, übernehmen oft die Funktion der Klassenlehrperson, wenn diese ausfällt. Damit dies gelingt, ist eine bereits vorhandene Beziehung zu den Schüler_innen wichtig. Der Frage nach der Beziehung zwischen der schulischen Heilpädagogin oder des Heilpädagogen und den Schüler_innen der Regelklasse geht diese Arbeit nach. Es ist dabei klar, dass verschiedene Faktoren einen Einfluss auf die Beziehung zwischen Lehrpersonen und Schüler_innen haben. Einer dieser Faktoren ist die Kooperation zwischen der Lehrperson und der heilpädagogischen Fachkraft. Die vorliegende Arbeit hat durch die Befragung von zehn Schulklassen inklusive schulischer Heilpädagog_in und Regelklassenlehrperson mittels Fragebogen versucht herauszufinden, ob in Klassen mit hohem Kooperationsverhalten der beiden beteiligten Lehrkräfte eine gute Beziehung zwischen der heilpädagogischer Fachkraft und den Schüler_innen herrscht und ob sich bestimmen lässt, welche Faktoren der Kooperation besonders für eine positive Beziehung zu den Schüler_innen verantwortlich sind. Dabei wurde festgestellt, dass sowohl Beziehung wie auch Kooperation zwei sehr komplexe Systeme sind, deren Untersuchung und Reduktion auf direkte Zusammenhänge sehr schwierig ist.

description: Magnetoelectric responses are a fundamental characteristic of materials that break time-reversal and inversion symmetries (notably multiferroics) and, remarkably, of "topological insulators" in which those symmetries are unbroken. Previous work has shown how to compute spin and lattice contributions to the magnetoelectric tensor. Here we solve the problem of orbital contributions by computing the frozen-lattice electronic polarization induced by a magnetic field. One part of this response (the "Chern-Simons term") can appear even in time-reversal-symmetric materials and has been previously shown to be quantized in topological insulators. In general materials there are additional orbital contributions to all parts of the magnetoelectric tensor; these vanish in topological insulators by symmetry and also vanish in several simplified models without time-reversal and inversion those magnetoelectric couplings were studied before. We give two derivations of the response formula, one based on a uniform magnetic field and one based on extrapolation of a long-wavelength magnetic field, and discuss some of the consequences of this formula.

description: The reduced dimensionality in two-dimensional materials leads to a wealth of unusual properties, which are currently explored for both fundamental and applied sciences. In order to study the crystal structure, edge states, the formation of defects and grain boundaries, or the impact of adsorbates, high-resolution microscopy techniques are indispensable. Here we report on the development of an electron holography (EH) transmission electron microscopy (TEM) technique, which facilitates high spatial resolution by an automatic correction of geometric aberrations. Distinguished features of EH beyond conventional TEM imaging are gap-free spatial information signal transfer and higher dose efficiency for certain spatial frequency bands as well as direct access to the projected electrostatic potential of the two-dimensional material. We demonstrate these features with the example of h-BN, for which we measure the electrostatic potential as a function of layer number down to the monolayer limit and obtain evidence for a systematic increase of the potential at the zig-zag edges.

description: Original quantum repeater protocols based on single-photon interference suffer from phase noise of the channel, which makes the long-distance quantum communication infeasible. Fortunately, two-photon interference type quantum repeaters can be immune to phase noise of the channel. However, this type quantum repeaters may still suffer from polarization disturbance of the channel. Here we propose a quantum repeaters protocol which is free of polarization disturbance of the channel based on the invariance of the anti-symmetric Bell state $|ψ^->=(|H>|V>-|V>|H>)/\sqrt{2}$ under collective noise. Our protocol is also immune to phase noise with the Sagnac interferometer configuration. Through single-atom cavity-QED technology and linear optics, this scheme can be implemented easily.

description: The detection of abnormal or critical system states is essential in condition monitoring. While much attention is given to promptly identifying anomalies, a retrospective analysis of these anomalies can significantly enhance our comprehension of the underlying causes of observed undesired behavior. This aspect becomes particularly critical when the monitored system is deployed in a vital environment. In this study, we delve into anomalies within the domain of Bio-Regenerative Life Support Systems (BLSS) for space exploration and analyze anomalies found in telemetry data stemming from the EDEN ISS space greenhouse in Antarctica. We employ time series clustering on anomaly detection results to categorize various types of anomalies in both uni- and multivariate settings. We then assess the effectiveness of these methods in identifying systematic anomalous behavior. Additionally, we illustrate that the anomaly detection methods MDI and DAMP produce complementary results, as previously indicated by research.

description: This investigation describes the synthesis of a dual stimuli-responsive, amphiphilic ABC tri-block copolymer (BCP) based on the functional monomers via RAFT polymerization. In this case, ABC-type BCP was prepared based on N-isopropylacrylamide, n-butyl acrylate, and 4-vinylpyridine in DMF solvent using cyanomethyl dodecyl trithiocarbonate as the RAFT agent and azobisisobutyronitrile as a thermal initiator in a subsequent macro-RAFT approach, respectively. The BCPs were characterized by SEC, 1H-NMR, FTIR spectroscopy, and DSC analyses. Temperature and pH-dependent properties of the smart BCP micelles in aqueous medium were investigated using dynamic light scattering. Transmission electron microscopic images were taken at cryogenic and dry conditions to study the morphology of molecular assemblies of block copolymers in an aqueous medium. The phase and topographical images were captured by atomic force microscopy to understand the assembly of block copolymers in solvents of different polarities. The morphology of BCP micelles was transformed from flower-like to spherical in the presence of solvents with different polarities (H2O or CHCl3). © 2020 The Authors.

description: We develop two complementary advances for training no-reference (NR) speech quality estimators with independent datasets. Multi-dataset finetuning (MDF) pretrains an NR estimator on a single dataset and then finetunes it on multiple datasets at once, including the dataset used for pretraining. AlignNet uses an AudioNet to generate intermediate score estimates before using the Aligner to map intermediate estimates to the appropriate score range. AlignNet is agnostic to the choice of AudioNet so any successful NR speech quality estimator can benefit from its Aligner. The methods can be used in tandem, and we use two studies to show that they improve on current solutions: one study uses nine smaller datasets and the other uses four larger datasets. AlignNet with MDF improves on other solutions because it efficiently and effectively removes misalignments that impair the learning process, and thus enables successful training with larger amounts of more diverse data.

Middle Meningeal Artery Embolization for the Management of Chronic Subdural Hematoma: Updated Systematic Review and Meta-Analysis
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2021

description: Background— Embolization of the middle meningeal artery (MMA) has emerged as a treatment strategy forchronic subdural hematoma (cSDH). We performed a systematic review and a meta-analysis of currently publishedliterature on MMA embolization in patients with cSDH.Methods— We searched Pubmed, Medline, and Cochrane databases for all studies that described the use of MMAembolization in patients with cSDH. We conducted a meta-analysis on the resulting studies and calculated eventrates of treatment failure, procedural complications, and clinical and radiological improvements. From studies thatcompared MMA embolization with conventional treatment, we calculated the rates of treatment failure as an outcomeof both methods using a fixed effects model.Results— In this review, we included eleven studies with 212 total cases of cSDH treated with MMA embolization.While the average length of time to follow-up evaluation ranged widely between studies (1 month to 4 years), ofthe included patients in this review, 97.2% (95% confidence intervals [CI] 94.2 to 100) showed reduced cSDH size;96.8% (95% CI 93.8 to 99.8) showed improvement on the modified Rankin Scale (mRS). Overall procedural com-plications were reported in 0.2% (95% CI -1.8 to 2.1) of patients. Three studies comparing MMA embolization andconventional treatment demonstrated that MMA embolization was associated with lower rates of treatment failuredefined as cSDH recurrence or persistence of cSDH of a width of greater than 10mm (odds ratio [OR] 0.06 CI 95%0.02 - 0.23, P<0.01; I2:0.0%).

Conclusion— Our meta-analysis shows that MMA embolization is effective in reducing cSDH volume and wasassociated with lower rates of treatment failure when compared with conventional therapy. Randomized clinical trialsexamining MMA embolization as a potential standard therapy in patients with cSDH are required.

description: In the DGP model, the ``self-accelerating'' solution is plagued by a ghost instability, which makes the solution untenable. This fact as well as all interesting departures from GR are fully captured by a four-dimensional effective Lagrangian, valid at distances smaller than the present Hubble scale. The 4D effective theory involves a relativistic scalar π, universally coupled to matter and with peculiar derivative self-interactions. In this paper, we study the connection between self-acceleration and the presence of ghosts for a quite generic class of theories that modify gravity in the infrared. These theories are defined as those that at distances shorter than cosmological, reduce to a certain generalization of the DGP 4D effective theory. We argue that for infrared modifications of GR locally due to a universally coupled scalar, our generalization is the only one that allows for a robust implementation of the Vainshtein effect--the decoupling of the scalar from matter in gravitationally bound systems--necessary to recover agreement with solar system tests. Our generalization involves an internal ``galilean'' invariance, under which π's gradient shifts by a constant. This symmetry constrains the structure of the πLagrangian so much so that in 4D there exist only five terms that can yield sizable non-linearities without introducing ghosts. We show that for such theories in fact there are ``self-accelerating'' deSitter solutions with no ghost-like instabilities. In the presence of compact sources, these solutions can support spherically symmetric, Vainshtein-like non-linear perturbations that are also stable against small fluctuations.

Diet, spatial ecology and energetics of echidnas: the significance of habitat and seasonal variation
Creators: name: Sprent, JA
Publisher: name: University Of Tasmania
Year: 2023

description: The ant- and termite-eating echidna is a solitary, monotreme mammal with a highly seasonal life history. I investigated several aspects of the seasonal energetics and ecology of free-ranging echidnas: the role of leptin in the annual mass cycle, seasonal and habitat effects on diet, the relationship between home range size and habitat quality, and the effect of habitat on the siting of echidna latrines. The echidna has a large seasonal variation in fat stores, which reach their maximum prior to hibernation. I hypothesised that the hormone leptin would have the same role in the echidna as in eutherian hibernators, i.e. that there would be a direct relationship between body mass and plasma leptin that would change to allow pre-hibernatory fattening. I found significant seasonal variations in plasma leptin, with the highest levels occurring in hibernation and in females during mating. The lowest levels were found in males after the reproductive period. Rather than the expected strong positive relationship between adiposity and plasma leptin I found a weak negative relationship, similar to that in reptiles and birds. To determine if there was any significant seasonal variation in diet associated with prehibernatory fattening I investigated diet using scat and stable isotope analysis. Echidna scats consisted largely of ants and the larvae of pasture cockchafer beetles. There was significant seasonal variation in percent occurrence of larvae, but not in the ant species found in scats or in the stable isotopic composition of echidna plasma. Although there was no difference in the prey items that contributed most to scat contents of animals living in different habitats, stable isotope analysis of blood showed a highly significant effect of habitat type on `˜í¬•^15N`. Female echidnas showed a significant negative relationship between the proportion of woodland habitat and home range size, whereas there was no such relationship for males, which had significantly larger home ranges. My data suggest that female home range is scaled to available resources, while male home range is probably scaled to maximise access to females. The role of latrines and their relationship to habitat was examined by a detailed survey of part of the field site, where many echidna home ranges were known to overlap. Latrines were located more frequently in scrub than in pasture or thick bush and the highest frequency of latrines occurred where there were two home ranges that overlapped. Latrines may be important in the spatial organisation of echidnas.

description: In-medium chiral symmetry breaking in confining potential models of QCD is examined. Past attempts to analyse these models have been hampered by infrared divergences that appear at non-zero temperature. We argue that previous attempts to circumvent this problem are not satisfactory and demonstrate a simple resolution. We also show that the expectation that confining models do not exhibit a chiral phase transition is incorrect. The effect of summing ring diagrams is investigated and we present the first determination of the temperature-density phase diagram for two model systems. We find that observables and the phase structure of the confinement models depend strongly on whether quark polarisation is accounted for. Finally, it appears that standard confinement models cannot adequately describe both hadron phenomenology and in-medium properties of QCD.

The first meeting of the Roman and Parthian empires : geopolitical context and consequences
Creators: name: Strk, FK
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis focuses upon the first meeting between the Roman and Parthian Empires in the first decade of the First Century BC. It places that meeting within its wider geopolitical context and considers its consequences for Romano-Parthian relations over the following decade. Near Eastern history of this period is confused, relying upon sparse textual evidence; as a consequence it is known as the Parthian Dark Age. This study addresses this shortfall in our evidence by reassessing the translations of Classical sources, employing Babylonian cuneiform texts, interpreting archaeological research and reinterpreting numismatic evidence. This thesis argues that the early development of Romano-Parthian relations was a product of wider geopolitical forces to an extent that has not been considered by previous scholarship. It argues that Parthia's passivity towards Rome's increasingly aggressive incursions into the Near East was a consequence of profound political and social upheaval within the Parthian Empire, hinted at in our primary sources. It argues further that Parthia's preoccupation with this internal discord, which included attempts at secession by various constituent kingdoms, allowed first King Tigranes of Armenia and then Rome to cement a foothold in the Near East south of the Taurus Mountains, at the expense of the Seleucid dynasties and Parthia's interests. This thesis employs a broader understanding of Near and Far Eastern sources than has been seen in previous studies and therefore addresses a gap in scholarship concerning the overall geopolitical picture of the Near East in the early First Century BC, and the roles Rome and Parthia played in shaping it. It closely examines the crucial preliminary period in Romano-Parthian relations in the vicinity of the Euphrates River‚ÄövÑvØa landmark that formed their frontier for three hundred years. Current scholarship has tended to focus on the later phase of Romano-Parthian interaction, particularly after Rome's annexation of Syria, and the more extensively documented Imperial period. This thesis aims to redress this imbalance. This study concludes that a broader examination of the relevant primary sources is required in order to illuminate the history of the Parthian Dark Age, and to make the Parthian Empire's interactions with Rome and its western neighbours more comprehensible. In addition it concludes that Parthia's crisis in the East explains its passivity towards Roman expansion into Asia Minor and the Near East in the first decades of the First Century BC.

This In Brief describes recent research on women’s informal urban livelihoods and economic participation.1 It forms part of the SSGM project Honiara Urbanisation: Managing Change, Harnessing Opportunities, which aims to better inform donors and policymakers about development priorities, opportunities, and prospects by engaging with a range of stakeholders, including settlement communities. From August to September 2016, the authors partnered with World Vision Solomon Islands to conduct five focus groups with a total of 50 women aged 18–65 from Sun Valley, White River, and Lord Howe settlements.2 The findings reflect the complexities of women’s livelihoods, which encompass not just engagement with the labour market, but traditional gender roles in the urban family and community, and networking and associations such as lending schemes and savings clubs.

description: We derive an effective field theory model for magnetic topological insulators and predict that a magnetic electronic gap persists on the surface for temperatures above the ordering temperature of the bulk. Our analysis also applies to interfaces of heterostructures consisting of a ferromagnetic and a topological insulator. In order to make quantitative predictions for MnBi2Te4 and for EuS-Bi2Se3 heterostructures, we combine the effective field theory method with density functional theory and Monte Carlo simulations. For MnBi2Te4 we predict an upwards Néel temperature shift at the surface up to 15%, while the EuS-Bi2Se3 interface exhibits a smaller relative shift. The effective theory also predicts induced Dzyaloshinskii-Moriya interactions and a topological magnetoelectric effect, both of which feature a finite temperature and chemical potential dependence.

description: Signatures of warm absorbers are seen in soft X-ray spectra of about half of all Seyfert1 galaxies observed and in some quasars and blazars. We use the thermal equilibrium curve to study the influence of the shape of the ionizing continuum, density and the chemical composition of the absorbing gas on the existence and nature of the warm absorbers. We describe circumstances in which a stable warm absorber can exist as a multiphase medium or one with continuous variation in pressure. In particular we find the following results: i) the warm absorber exists only if the spectral index of the X-ray power-law ionizing continuum $α> 0.2$ and has a multiphase nature if $α\sim 0.8$, which interestingly is the spectral index for most of the observed Seyfert 1 galaxies; ii) thermal and ionization states of highly dense warm absorbers are sensitive to their density if the ionizing continuum is sufficiently soft, i.e. dominated by the ultraviolet iii) absorbing gas with super-Solar metallicity is more likely to have a multiphase nature; iv) the nature of the warm absorber is significantly influenced by the absence of iron and associated elements which are produced in the later stages of star formation history in supernovae of type Ia.

More precisely, we investigate the $^1S$ ground state properties of two model systems: the Moshinsky atom (in which the electrons move in a quadratic potential) and the spherium model (in which they move on the surface of a sphere). A comparison with their Coulombic counterparts is made, which highlights the main differences of the $\Ec$ in both the weakly and strongly correlated limits. Moreover, we show that the Schrödinger equation of the spherium model is exactly solvable for two values of the dimension ($D = 1 \text{and} 3$), and that the exact wave function is based on Mathieu functions.

description: Magnetization switching using in-plane charge current recently has been widely investigated in heavy metal/ferromagnet bilayers with the switching mechanism usually attributed to the action of the spin-orbit coupling. Here we study in-plane current induced magnetization switching in model epitaxial bilayers that consist of Au(001) and Fe(001) grown on MgO(001). We use the planar Hall effect combined with magnetooptical Kerr effect (MOKE) microscopy to investigate magnetic properties of the bilayers and current-induced switching. We show that a current density beyond 1.4×107 A/cm can be employed for reproducible electrical switching of the magnetization between multiple stable states that correspond to different arrangements of magnetic domains with magnetization direction along one of the in-plane easy magnetization axes of the Fe(001) film. Lower current densities result in stable intermediate transversal resistances which are interpreted based on MOKE-microscopy investigations as resulting from the current-induced magnetic domain structure that is formed in the area of the Hall cross. We find that the physical mechanism of the current-induced magnetization switching of the Au/Fe/MgO(001) system at room temperature can be fully explained by the Oersted field, which is generated by the charge current flowing mostly through the Au layer.

description: In the development and optimization of imaging methods, photoacoustic imaging (PAI) has become a powerful tool for preclinical biomedical diagnosis and detection of cancer. PAI probes can improve contrast and help identify pathogenic tissue. Such contrast agents must meet several requirements: they need to be biocompatible, and absorb strongly in the near-infrared (NIR) range, while relaxing the photoexcited state thermally and not radiatively. In this work, polymer nanoparticles are produced with croconaine as a monomer unit. Small molecular croconaine dyes are known to act as efficient pigments, which do not show photoluminescence. Here, for the first time croconaine copolymer nanoparticles are produced from croconic acid and a range of aromatic diamines. Following a dispersion polymerization protocol, this approach yields monodisperse particles of adjustable size. All synthesized polymers exhibit broad absorption within the NIR spectrum and therefore represent suitable candidates as contrast agents for PAI. The optical properties of these polymer particles are discussed with respect to the relation between particle size and outstanding photoacoustic performance. Biocompatibility of the polymer particles is demonstrated in cell viability experiments. © The Authors. Published by Wiley-VCH GmbH
What do you need a whitefella's education for? : A yarn about Aboriginal philosophy
Creators: name: Gower, LK
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis explores two central questions: one, why does the field of Aboriginal philosophy remain largely unestablished?; and two, what shape might Aboriginal philosophy take? The first two chapters of the paper will address the first question. Value structures that are biased towards western philosophies will be identified as a key reason for the relative absence of Aboriginal philosophies compared to European and American philosophies taught and researched in Australia at present. A Nietzschean analysis of these value structures will demonstrate that the lack of value attributed to Aboriginal philosophy in Australia at present is unwarranted; it will also provide a platform from which a revaluation of competing narratives can take place. The exploration of a number of Aboriginal Dreaming stories will emphasise that such stories contain complex understandings of the world that are of equal value to any other philosophy the world has produced; neither 'folk' philosophy nor 'myth' nor any additional descriptions that suggest an inferior, simplistic worldview. The last chapter will address the second question by providing an exploratory step towards Aboriginal philosophy. The aim of this thesis is to provide a basis for further research into what Aboriginal philosophy or philosophies may look like, and the development of a dialogue between Aboriginal philosophy and mainstream philosophy as valued, respected, equal fields of intellectual knowledge.

description: We present the HERA CO-Line Extragalactic Survey (HERACLES), an atlas of CO emission from 18 nearby galaxies that are also part of The HI Nearby Galaxy Survey (THINGS) and the Spitzer Infrared Nearby Galaxies Survey (SINGS). We used the HERA multi-pixel receiver on the IRAM 30-m telescope to map the CO J=2-1 line over the full optical disk (defined by the isophotal radius r_25) of each target, at 13" angular resolution and 2.6 km/s velocity resolution. Here we describe the observations and reduction of the data and show channel maps, azimuthally averaged profiles, integrated intensity maps, and peak intensity maps. The implied H2 masses range from 7 \times 10^6 to 6 \times 10^9 M_sun, with four low metallicity dwarf irregular galaxies yielding only upper limits. In the cases where CO is detected, the integrated H2-to-HI ratios range from 0.02 - 1.13 and H2-to-stellar mass ratios from 0.01 to 0.25. Exponential scale lengths of the CO emission for our targets are in the range 0.8 - 3.2 kpc, or 0.2 \pm 0.05 r_25. The intensity-weighted mean velocity of CO matches that of HI very well, with a 1σscatter of only 6 km/s. The CO J=2-1 / J=1-0 line ratio varies over a range similar to that found in the Milky Way and other nearby galaxies, \sim 0.6 - 1.0, with higher values found in the centers of galaxies. The typical line ratio, \sim 0.8, could be produced by optically thick gas with an excitation temperature of \sim 10 K.

description: OBJECTIVES: Chiropractic care is a service that operates outside of the conventional medical system and is reimbursed by Medicare. Our objective was to examine the extent to which accessibility of chiropractic care affects spending on medical spine care among Medicare beneficiaries. STUDY DESIGN: Retrospective cohort study that used beneficiary relocation as a quasi-experiment. METHODS: We used a combination of national data on provider location and Medicare claims to perform a quasi-experimental study to examine the effect of chiropractic care accessibility on healthcare spending. We identified 84,679 older adults enrolled in Medicare with a spine condition who relocated once between 2010 and 2014. For each year, we measured accessibility using the variable-distance enhanced 2-step floating catchment area method. Using data for the years before and after relocation, we estimated the effect of moving to an area of lower or higher chiropractic accessibility on spine-related spending adjusted for access to medical physicians. RESULTS: There are approximately 45,000 active chiropractors in the United States, and local accessibility varies considerably. A negative dose-response relationship was observed for spine-related spending on medical evaluation and management as well as diagnostic imaging and testing (mean differences, $20 and $40, respectively, among those exposed to increasingly higher chiropractic accessibility; P CONCLUSIONS: Among older adults, access to chiropractic care may reduce medical spending on services for spine conditions.

description: Weighted discrete Hilbert transforms $(a_n)_n \mapsto \big(\sum_n a_n v_n/(λ_j-γ_n)\big)_j$ from $\ell^2_v$ to $\ell^2_w$ are considered, where $Γ=(γ_n)$ and $Λ=(λ_j)$ are disjoint sequences of points in the complex plane and $v=(v_n)$ and $w=(w_j)$ are positive weight sequences. It is shown that if such a Hilbert transform is unitary, then $Γ\cupΛ$ is a subset of a circle or a straight line, and a description of all unitary discrete Hilbert transforms is then given. A characterization of the orthogonal bases of reproducing kernels introduced by L. de Branges and D. Clark is implicit in these results: If a Hilbert space of complex-valued functions defined on a subset of $\CC$ satisfies a few basic axioms and has more than one orthogonal basis of reproducing kernels, then these bases are all of Clark's type.

description: This bibliography is downloadable in MS Word format.  The annotated bibliography

is intended to provide an overview of different aspects of transportation in

rural America.  Emphasis is on those studies published within the last 10 years,

but some earlier citations are also included.  Citations are organized into five

categories.  Studies dealing with the availability, demand, and condition of

rural infrastructure are described first.  Second, studies dealing with the

importance of transportation for rural development are examined.  Third, studies

dealing with Federal and local governmental issues are identified, including

inancing, planning, and regulatory issues.  Fourth, studies not fitting into

one of the previous groupings, covering topics such as social services

transportation, safety issues, and environmental concerns, are discussed.

A fifth section highlights miscellaneous references, such as maps, atlases,

and bibliographies.  Finally, a non-annotated bibliography of additional

studies on rural transportation is included.  This paper was prepared under an

interagency reimbursable agreement (98-IA-1844-AAC) with the U.S. Department of

Transportation.  67 p.
A strengthening and a multipartite generalization of the Alon-Boppana-Serre Theorem

description: The Alon-Boppana theorem confirms that for every $ε>0$ and every integer $d\ge3$, there are only finitely many $d$-regular graphs whose second largest eigenvalue is at most $2\sqrt{d-1}-ε$. Serre gave a strengthening showing that a positive proportion of eigenvalues of any $d$-regular graph must be bigger than $2\sqrt{d-1}-ε$. We provide a multipartite version of this result. Our proofs are elementary and work also in the case when graphs are not regular. In the simplest, monopartite case, our result extends the Alon-Boppana-Serre result to non-regular graphs of minimum degree $d$ and bounded maximum degree. The two-partite result shows that for every $ε>0$ and any positive integers $d_1,d_2,d$, every $n$-vertex graph of maximum degree at most $d$, whose vertex set is the union of (not necessarily disjoint) subsets $V_1,V_2$, such that every vertex in $V_i$ has at least $d_i$ neighbors in $V_{3-i}$ for $i=1,2$, has $Ω_ε(n)$ eigenvalues that are larger than $\sqrt{d_1-1}+\sqrt{d_2-1}-ε$. Finally, we strengthen the Alon-Boppana-Serre theorem by showing that the lower bound $2\sqrt{d-1}-ε$ can be replaced by $2\sqrt{d-1} + δ$ for some $δ>0$ if graphs have bounded "global girth". On the other side of the spectrum, if the odd girth is large, then we get an Alon-Boppana-Serre type theorem for the negative eigenvalues as well.
