description: O presente artigo objetiva resgatar os antecedentes, bem como a trajetória da construção do Espaço Europeu de Ensino Superior – EEES –, apontando que a ideia de sua organização é anterior ao Processo de Bolonha, embora este tenha sido sua face mais conhecida. O texto busca cotejar essa construção com a busca de uma nova ideia de cidadania europeia. Considera-se no texto os marcos de repercussão política, jurídica e educacional no âmbito do concerto europeu contemporâneo, idealizando um conceito de Europa alargada e, igualmente, um espaço para a sua projeção no campo educacional no mundo globalizado, contribuindo para a alocação e desenvolvimento da cidadania europeia, valor que se vincula aos campos da cultura e da educação e,neste caso, à constituição de uma universidade europeia com harmonização de estrutura, currículo, tempo, créditos e níveis de formação. O EEES passou a existir formalmente, a partir de 2010, embora sua estruturação continue em processo, seja por conta das questões próprias dos 48 países que o compõem, seja pelas questões internas das universidades que a ele se agregam.

description: The critical behaviour of the one-dimensional q-state Potts model with long-range interactions decaying with distance r as $r^{-(1+σ)}$ has been studied in the wide range of parameters $0 < σ\le 1$ and $\frac{1}{16} \le q \le 64$. A transfer matrix has been constructed for a truncated range of interactions for integer and continuous q, and finite range scaling has been applied. Results for the phase diagram and the correlation length critical exponent are presented.

description: The long-range $ΛN-ΣN$ interaction is modeled by a configuration space meson-exchange potential matrix coupling to channels with $Δ$ and $Σ(1385)$ isobars. An inner boundary condition, based on $R$-matrix theory, replaces form factors for short-range effects and includes the effects of free quark configurations. An excellent fit is obtained to the available data, with only the energy-independent boundary conditions as free parameters. The effect of isobar thresholds is shown to be substantial in several partial waves and is crucial to the understanding of the higher energy $ΛN$ elastic scattering data.

description: This thesis is a travel memoir recounting Abigail's experience studying abroad in Edinburgh, Scotland, in the spring of 2020. In it, she explores many aspects of Scottish history and culture, including the Scottish Gaelic language, Scottish independence, and the way Scots relate to the landscape around them. It is also a coming-of-age story, as Abigail learns to live and travel on her own. Finally, the thesis discusses the COVID-19 pandemic, which cut Abigail's semester abroad short, and what this might mean for the future of travel. She argues that travel is an important experience that makes us question our perspective and see the world in a new light.

description: The recent detection of GRB 170817A and GW170817 constrains the speed of gravity waves $c_T$ to be that of light, which severely restricts the landscape of modified gravity theories that impact the cosmological evolution of the universe. In this work, we investigate the presence of black hole hair in the remaining viable cosmological theories of modified gravity that respect the constraint $c_T=1$. We focus mainly on scalar-tensor theories of gravity, analyzing static, asymptotically flat black holes in Horndeski, Beyond Horndeski, Einstein-Scalar-Gauss-Bonnet, and Chern-Simons theories. We find that in all of the cases considered here, theories that respect $c_T=1$ do not allow for hair, or have negligible hair. We further comment on vector-tensor theories including Einstein Yang-Mills, Einstein-Aether, and Generalised Proca theories, as well as bimetric theories.

description: Advancements in digital technologies make it easy to modify the content of digital images. Hence, ensuring digital images integrity and authenticity is necessary to protect them against various attacks that manipulate them. We present a Deep Learning (DL) based dual invisible watermarking technique for performing source authentication, content authentication, and protecting digital content copyright of images sent over the internet. Beyond securing images, the proposed technique demonstrates robustness to content-preserving image manipulations. It is also impossible to imitate or overwrite watermarks because the cryptographic hash of the image and the dominant features of the image in the form of perceptual hash are used as watermarks. We highlighted the need for source authentication to safeguard image integrity and authenticity, along with identifying similar content for copyright protection. After exhaustive testing, we obtained a high peak signal-to-noise ratio (PSNR) and structural similarity index measure (SSIM), which implies there is a minute change in the original image after embedding our watermarks. Our trained model achieves high watermark extraction accuracy and to the best of our knowledge, this is the first deep learning-based dual watermarking technique proposed in the literature.

description: We present results of a population synthesis study aimed at examining the role of spin-kick alignment in producing a correlation between the spin period of the first-born neutron star and the orbital eccentricity of observed double neutron star binaries in the Galactic disk. We find spin-kick alignment to be compatible with the observed correlation, but not to alleviate the requirements for low kick velocities suggested in previous population synthesis studies. Our results furthermore suggest low- and high-eccentricity systems may form through two distinct formation channels distinguished by the presence or absence of a stable mass transfer phase before the formation of the second neutron star. The presence of highly eccentric systems in the observed sample of double neutron stars may furthermore support the notion that neutron stars accrete matter when moving through the envelope of a giant companion.

Radiation from the non-extremal fuzzball

description: The fuzzball proposal says that the information of the black hole state is distributed throughout the interior of the horizon in a `quantum fuzz'. There are special microstates where in the dual CFT we have `many excitations in the same state'; these are described by regular classical geometries without horizons. Jejjala et.al constructed non-extremal regular geometries of this type. Cardoso et. al then found that these geometries had a classical instability. In this paper we show that the energy radiated through the unstable modes is exactly the Hawking radiation for these microstates. We do this by (i) starting with the semiclassical Hawking radiation rate (ii) using it to find the emission vertex in the CFT (iii) replacing the Boltzman distributions of the generic CFT state with the ones describing the microstate of interest (iv) observing that the emission now reproduces the classical instability. Because the CFT has `many excitations in the same state' we get the physics of a Bose-Einstein condensate rather than a thermal gas, and the usually slow Hawking emission increases, by Bose enhancement, to a classically radiated field. This system therefore provides a complete gravity description of information-carrying radiation from a special microstate of the nonextremal hole.

In these movements across the globe, a plural scenario of roles and representations of women emerge. In discussing the connection between methodology and epistemology, the article aims to contribute to the debate on the relationship between the production of knowledge about women and the transnational, feminist and decolonial perspectives.

description: Atomic Carbon can be an efficient tracer of the molecular gas mass, and when combined to the detection of high-J and low-J CO lines it yields also a sensitive probe of the power sources in the molecular gas of high redshift galaxies. The recently installed SEPIA5 receiver at the focus of the APEX telescope has opened up a new window at frequencies 159 - 211 GHz allowing the exploration of the Atomic Carbon in high-z galaxies, at previously inaccessible frequencies from the ground. We have targeted three gravitationally lensed galaxies at redshift of about 3 and conducted a comparative study of the observed high-J CO/CI ~ratios with well-studied nearby galaxies. Atomic Carbon (CI(2-1)) was detected in one of the three targets and marginally in a second, while in all three targets the $J=7\to6$ CO line is detected. The CO(7-6)/CI(2-1), CO(7-6)/CO(1-0) line ratios and the CO(7-6)/(far-IR continuum) luminosity ratio are compared to those of nearby objects. A large excitation status in the ISM of these high-z objects is seen, unless differential lensing unevenly boosts the CO line fluxes from the warm and dense gas more than the CO(1-0), CI(2-1), tracing a more widely distributed cold gas phase. We provide estimates of total molecular gas masses derived from the atomic Carbon and the Carbon monoxide CO(1-0), which within the uncertainties turn out to be equal.

description: The summer camp community thinks they know how camp influences youth development, but there is a knowledge gap when it comes to leadership. Currently, camp research has claimed that there are improvements in leadership but has failed to define what leadership means for campers. The purpose of this thesis is to establish factors for leadership development in the context of summer camps and show there are positive changes for campers. The research was completed through the use of self-reporting surveys administered to campers at Camp Champions. The main goal was to understand which factors of leadership were being developed if any at all. Another central question was if the way people wrote about their leadership experiences correlated with their leadership gains. The results predict leadership changes among campers across the dimensions of self-efficacy and considerate leadership, which increases our knowledge of how camp improves adolescent leadership experiences and contributes to the targeted skills developments camps aspire to provide. These contributions are discussed in the context of the studies' limitations.

description: The results of extensive Monte Carlo simulations of magnetic-field induced transitions in the xy model on a stacked triangular lattice with antiferromagnetic intraplane and ferromagnetic interplane interactions are discussed. A low-field transition from the paramagnetic to a 3-state (Potts) phase is found to be very weakly first order with behavior suggesting tricriticality at zero field. In addition to clarifying some long-standing ambiguity concerning the nature of this Potts-like transition, the present work also serves to further our understanding of the critical behavior at $T_N$, about which there has been much controversy.

description: Creative destruction is a term first coined by economist Joseph Schumpeter to describe the emergence of new products and processes that are created in the wake of the destruction of old ones. This phenomenon has been attributed to being an essential catalyst of economic growth that shapes how industries and markets will look in the future. However, corporate political participation, such as lobbying, may be having an effect on this process due to the potential formation of vested interests between firms and political actors that preserves the status quo. In this paper I perform a literature review of creative destruction while exploring the theoretical factors that allow for creative destruction to take place in a manner that progresses the economy forward. I also review literature on corporate political activity to understand its effects on firms and markets. Next, I take a more quantitative approach by investigating firms with political ties, specifically in the energy industry, through regression and data analysis. Are these firms trading off long term economic growth of their industry for short term success? This is relevant in increasing our understanding of how certain forms of current private sector relationships with the government might be affecting the future of their industry. The regression results analyzing the relationship between innovation and lobbying were not statistically significant but other data and the literature surrounding the topics point toward the possibility of larger firms that lobby not properly utilizing their resources in the most efficient manner. It was also found that escaping old ideas and the emotional difficulty of destruction can hold back incumbent firms from constantly innovating. Industries in which entrants decide to cooperate with incumbents leads to less competition, thus decreasing the likelihood of both adopting new technology and enacting the process of creative destruction. Political participation such as lobbying, meanwhile, can be used as an effective means to influence the government and to increase profits.

description: The past decade has witnessed a substantial increase in the number of startups and companies offering AI-based solutions for clinical decision support in medical institutions. However, the critical nature of medical decision-making raises several concerns about relying on external software. Key issues include potential variations in image modalities and the medical devices used to obtain these images, potential legal issues, and adversarial attacks. Fortunately, the open-source nature of machine learning research has made foundation models publicly available and straightforward to use for medical applications. This accessibility allows medical institutions to train their own AI-based models, thereby mitigating the aforementioned concerns. Given this context, an important question arises: how much data do medical institutions need to train effective AI models? In this study, we explore this question in relation to breast cancer detection, a particularly contested area due to the prevalence of this disease, which affects approximately 1 in every 8 women. Through large-scale experiments on various patient sizes in the training set, we show that medical institutions do not need a decade's worth of MRI images to train an AI model that performs competitively with the state-of-the-art, provided the model leverages foundation models. Furthermore, we observe that for patient counts greater than 50, the number of patients in the training set has a negligible impact on the performance of models and that simple ensembles further improve the results without additional complexity.

Kaon-Nucleon Scattering Amplitudes and Z$^*$-Enhancements from Quark Born Diagrams

description: We derive closed form kaon-nucleon scattering amplitudes using the ``quark Born diagram" formalism, which describes the scattering as a single interaction (here the OGE spin-spin term) followed by quark line rearrangement. The low energy I=0 and I=1 S-wave KN phase shifts are in reasonably good agreement with experiment given conventional quark model parameters. For $k_{lab}> 0.7$ Gev however the I=1 elastic phase shift is larger than predicted by Gaussian wavefunctions, and we suggest possible reasons for this discrepancy. Equivalent low energy KN potentials for S-wave scattering are also derived. Finally we consider OGE forces in the related channels K$Δ$, K$^*$N and K$^*Δ$, and determine which have attractive interactions and might therefore exhibit strong threshold enhancements or ``Z$^*$-molecule" meson-baryon bound states. We find that the minimum-spin, minimum-isospin channels and two additional K$^*Δ$ channels are most conducive to the formation of bound states. Related interesting topics for future experimental and theoretical studies of KN interactions are also discussed.

description: "What operations, tactics, and strategies that successful small businesses perform produce the most effective and persistent Cultural Equity among new cycles of student populations?" In this paper I will focus on retail and restaurant locations from the intersection of MLK Boulevard and Guadalupe Street to the intersection of Rio Grande Street and 29th Street. For small businesses, this operating environment has immense foot traffic from the 50,000+ students on UT Austin’s campus. Students spend only a few years on campus and then move away, so businesses are presented with a unique challenge of customer churn. Assuming that small businesses do not benefit from pre-existing brand awareness and customer interest that larger chains do among new student populations, word of mouth marketing comes at a premium, minimizing the cost of customer acquisition. Through survey analyses I have found that firms that have survived for a lengthy period in this environment tend to have some measure of Cultural Equity. Here, Cultural Equity for a small business is defined as a composite score of brand awareness percentage, net promoter score, and the likelihood that a customer would take an out-of-town friend to a business’ location. Cultural Equity represents the degree to which a small business is known, recommended by customers, and is shared with out-of-town friends; it is a measure of word of mouth marketing and customer advocacy. In this paper, I focus on understanding how a firm might cultivate Cultural Equity.

description: We describe the calculation of the next-to-next-to-leading order (NNLO) QCD corrections to three-jet production and related event shape observables in electron-positron annihilation. Infrared singularities due to double real radiation at tree level and single real radiation at one loop are subtracted from the full QCD matrix elements using antenna functions, which are then integrated analytically and added to the two loop contribution. Using this antenna subtraction method, we obtain numerically finite contributions from five-parton and four-parton processes, and observe an explicit analytic cancellation of infrared poles in the four-parton and three-parton contributions. All contributions are implemented in a flexible parton-level event generator programme, allowing the numerical computation of any infrared-safe observable related to three-jet final states to NNLO accuracy.

description: String compactifications with T-duality twists are revisited and the gauge algebra of the dimensionally reduced theories calculated. These reductions can be viewed as string theory on T-fold backgrounds, and can be formulated in a `doubled space' in which each circle is supplemented by a T-dual circle to construct a geometry which is a doubled torus bundle over a circle. We discuss a conjectured extension to include T-duality on the base circle, and propose the introduction of a dual base coordinate, to give a doubled space which is locally the group manifold of the gauge group. Special cases include those in which the doubled group is a Drinfel'd double. This gives a framework to discuss backgrounds that are not even locally geometric.

description: We present LOFAR $120-168$ MHz images of the merging galaxy cluster Abell 1240 that hosts double radio relics. In combination with the GMRT $595-629$ MHz and VLA $2-4$ GHz data, we characterised the spectral and polarimetric properties of the radio emission. The spectral indices for the relics steepen from their outer edges towards the cluster centre and the electric field vectors are approximately perpendicular to the major axes of the relics. The results are consistent with the picture that these relics trace large-scale shocks propagating outwards during the merger. Assuming diffusive shock acceleration (DSA), we obtain shock Mach numbers of $\mathcal{M}=2.4$ and $2.3$ for the northern and southern shocks, respectively. For $\mathcal{M}\lesssim3$ shocks, a pre-existing population of mildly relativistic electrons is required to explain the brightness of the relics due to the high ($>10$ per cent) particle acceleration efficiency required. However, for $\mathcal{M}\gtrsim4$ shocks the required efficiency is $\gtrsim1\%$ and $\gtrsim0.5\%$, respectively, which is low enough for shock acceleration directly from the thermal pool. We used the fractional polarization to constrain the viewing angle to $\geqslant(53\pm3)^\circ$ and $\geqslant(39\pm5)^\circ$ for the northern and southern shocks, respectively. We found no evidence for diffuse emission in the cluster central region. If the halo spans the entire region between the relics ($\sim1.8\,\text{Mpc}$) our upper limit on the power is $P_\text{1.4 GHz}=(1.4\pm0.6)\times10^{23}\,\text{W}\text{Hz}^{-1}$ which is approximately equal to the anticipated flux from a cluster of this mass. However, if the halo is smaller than this, our constraints on the power imply that the halo is underluminous.

The Effects of Electro-weak Phase Transition Dynamics on Baryogenesis and Primordial Nucleosynthesis

description: The evolution of the electro-weak phase transition, including reheating due to the release of latent heat in shock waves, is calculated for various values of as yet unknown parameters of electro-weak theory such as latent heat and bubble wall surface tension. We show that baryon production, which occurs in the vicinity of the bubble walls of the phase transition, can be a sensitive function of bubble wall velocity, and this velocity dependence is important to include in the calculation of the baryon density of the universe. There is a sensitive velocity dependence for all mechanisms of baryon production, depending on the magnitude of velocity of the bubble wall, and we examine in particular an inverse velocity dependence on baryon production, which is predicted by the charge transport mechanism of baryon production. For this mechanism we find both an enhancement of baryon production and the generation of inhomogeneities during the electro-weak phase transition. We calculate the magnitude of the baryon enhancement, which can be as large as a few orders of magnitude, depending on the parameters of the theory, and we calculate the size and amplitude of the inhomogeneities generated. We determine that the inhomogeneities generated in a thermally nucleated electro-weak phase transition are to small to survive diffusive processes and effect the nucleosynthesis epoch. We also examine the possibility that a phase transition nucleated by other means, such as by the presence of cosmic strings, may produce inhomogeneities that could effect

description: Traditional histories of women’s lives during World War II have stressed the dramatic changes that dominated the war period. This thesis offers a revisionist argument analyzing the ways government and private industry collaborated to promote continuity in women’s lives during and after the war. A close analysis of internal government memos, archived communications between the government and Madison Avenue, advertisements, women’s magazine articles, and wartime fiction offers insight into the ways propaganda and popular culture pressured women to preserve pre-war gender relations. The doyens of culture and the warlords of Washington insisted that the ideal, patriotic woman remain devoted to homemaking, motherhood, and beauty above all else. Emphasizing these pillars of traditional womanhood and femineity, propaganda and policy makers demanded wartime women adapt to the harsh realities of the homefront while pretending as if nothing had changed. Government and private interests extracted significant sacrifice from the wartime woman while offering her little lasting autonomy or power in return. Incorporating oral histories of women’s lived experiences during the war period, this thesis explores the complicated interplay between popular media and private belief. A central focus of this study is the ways women reinforced, reflected, and resisted propaganda during the war and beyond.

description: As universidades convivem com o contexto internacional desde sua gênese, quando recebiam o nome de “Comunidades Internacionais”, pois buscavam a universalidade do conhecimento e do saber. Atualmente, aabertura institucional assumiu um papel estratégico para essas organizações, passando a ser parte dos planos dedesenvolvimento. Considerando a relevância que a globalização trouxe para todos os tipos de relações entrepaíses e o investimento que o governo brasileiro tem feito no fomento à abertura internacional da educação superior, observou-se a importância de se estudar esse processo no cenário brasileiro. Este estudo buscou, assim, compreender o processo de internacionalização e suas implicações na gestão universitária no Brasil, com ênfase na mobilidade acadêmica. Para tanto, foi feita uma pesquisa analítica que trouxe um levantamento teórico acerca da internacionalização do ensino superior e da mobilidade acadêmica no contexto da gestão universitária noBrasil, bem como seus conceitos e desmembramentos nos últimos anos, além das tendências para o ensinosuperior. Foi possível verificar implicações de cunho financeiro, tecnológico, cultural e social desse processonão só na gestão universitária, mas também na sociedade de forma geral. Ao fim, compreende-se que a internacionalização do ensino superior brasileiro é um fenômeno paradoxal que traz benefícios para a formaçãodos acadêmicos e resultados para o país (além de seguir uma tendência mundial), ao mesmo tempo em que évisto como um agente enfraquecedor da soberania nacional e como uma ferramenta econômica que traz privilégios para poucos, devido à sua atuação passiva focada no envio de acadêmicos dos quais se espera retorno econômico.

description: We perform a statistical assessment of solar wind stability at 1 AU against ion sources of free energy using Nyquist's instability criterion. In contrast to typically employed threshold models which consider a single free-energy source, this method includes the effects of proton and He$^{2+}$ temperature anisotropy with respect to the background magnetic field as well as relative drifts between the proton core, proton beam, and He$^{2+}$ components on stability. Of 309 randomly selected spectra from the Wind spacecraft, $53.7\%$ are unstable when the ion components are modeled as drifting bi-Maxwellians; only $4.5\%$ of the spectra are unstable to long-wavelength instabilities. A majority of the instabilities occur for spectra where a proton beam is resolved. Nearly all observed instabilities have growth rates $γ$ slower than instrumental and ion-kinetic-scale timescales. Unstable spectra are associated with relatively-large He$^{2+}$ drift speeds and/or a departure of the core proton temperature from isotropy; other parametric dependencies of unstable spectra are also identified.

Luttinger Liquid Instability in the One Dimensional t-J Model

Year: 1993
Subjects: subject: Condensed Matter (cond-mat)

description: We study the t-J model in one dimension by numerically projecting the true ground state from a Luttinger liquid trial wave function. We find the model exhibits Luttinger liquid behavior for most of the phase diagram in which interaction strength and density are varied. However at small densities and high interaction strengths a new phase with a gap to spin excitations and enhanced superconducting correlations is found. We show this phase is a Luther-Emery liquid and study its correlation functions.

Um conceito reinterpretado ao longo do século: do intelectual individualista de Durkheim ao intelectual coletivo de Bourdieu

description: Para contribuir com o debate sobre os intelectuais recorremos a dois sociólogos, distanciados um do outro cerca de um século: Émile Durkheim (1858-1917) e Pierre Bourdieu (1930-2002). O primeiro preconiza a relação entre uma “moral individualista” e o papel do intelectual. Esta reflexão integra o conjunto de suas apostas na coesão social e na moral laica, indispensáveis à promoção do progresso e da ordem nas sociedades em processo crescente de diferenciação. A perspectiva de Bourdieu volta-se à necessidade de “reinventar uma espécie de intelectual coletivo segundo o modelo do que foram os enciclopedistas”. Segundo ele, um novo desafio se impõe ao intelectual coletivo: mobilizar a ciência, e a sociologia em particular, na luta contra os usos abusivos da própria ciência e da autoridade científica. As ideias destes pensadores oferecem chaves de leitura que inspiram o desenvolvimento de uma sociologia histórica voltada à educação no pensamento social brasileiro.

description: This thesis reflects on the inspiration, creation, and in-process performance of A Normal Misfortune: More or Less the Story of Iphis, a dance theatre adaptation of Chapter nine of Ovid's Metamorphoses which premiered at UT Austin's 2021 Cohen New Works Festival. In this thesis, I combine queer theory, performance analysis, and performance-as-research methodologies to consider how postmodern, dance-theatre adaptations 'queer' their literary source texts by repurposing themes and structures from the text and manipulating queer aesthetics onstage. I use José Esteban Muñoz's scholarship to ask how twenty-first century creators and performers might "disidentify" with mainstream, normative queer and trans representation, and I use adaptation to address those disidentifications. I analyze adaptations of classical source texts by Mary Zimmerman, Michelle Ellsworth, and Katy Pyle to draw inspiration from a wide range of approaches to adaptation. I investigate the legacies of Judson Dance Theater, Michelle Ellsworth, and TikTok as aesthetic and methodological inspiration for A Normal Misfortune. I use these sources to create my own adaptation that liberally repurposes theme and structures from its source text, remains open to influence from the outside world until the last possible moment, and centers queerness and queer aesthetics. Finally, I reflect on the process of creating A Normal Misfortune, with an eye towards its future development.
Deformation of extremal black holes from stringy interactions

description: Black holes are a powerful setting for studying general relativity and theories beyond GR. However, analytical solutions for rotating black holes in beyond-GR theories are difficult to find because of the complexity of such theories. In this paper, we solve for the deformation to the near-horizon extremal Kerr metric due to two example string-inspired beyond-GR theories: Einstein-dilaton-Gauss-Bonnet, and dynamical Chern-Simons theory. We accomplish this by making use of the enhanced symmetry group of NHEK and the weak-coupling limit of EdGB and dCS. We find that the EdGB metric deformation has a curvature singularity, while the dCS metric is regular. From these solutions we compute orbital frequencies, horizon areas, and entropies. This sets the stage for analytically understanding the microscopic origin of black hole entropy in beyond-GR theories.

description: A general method of computing string corrections to the Kähler metric and Yukawa couplings is developed at the one-loop level for a general compactification of the heterotic superstring theory. It also provides a direct determination of the so-called Green-Schwarz term. The matter metric has an infrared divergent part which reproduces the field-theoretical anomalous dimensions, and a moduli-dependent part which gives rise to threshold corrections in the physical Yukawa couplings. Explicit expressions are derived for symmetric orbifold compactifications.

description: Introduction: Brain abscess is an uncommon and potentially life-threatening infection of the CNS that can be caused by a range of different pathogens including bacteria, fungi, and parasites. A multidisciplinary approach is important and anti-infective treatment remains crucial. Here, we review anti-infective treatment of brain abscess. Areas covered: We used the terms ‘(Brain abscess[ti] AND (antibiotic* OR treatment)) NOT case report’), to conduct a search in the PubMed. Additional papers were identified by cross-reference checking and by browsing textbooks of infectious diseases and neurology. Commentary: Empiric treatment of bacterial brain abscess consists of cefotaxime and metronidazole with the addition of vancomycin if meticilline-resistant Staphylococcus aureus is suspected. For severely immuno-suppressed patients, for example transplant recipients, voriconazole and trimethoprim-sulfamethoxazole or sulfadiazine should be added. Increased knowledge of the pharmacokinetic profile of anti-infective treatments may help to improve the treatment of brain abscess. Future studies should address efficacy and safety of continuous abscess drainage, mode of anti-infective administration (continuous vs. bolus), and anti-infective treatments in immuno-suppressed patients.
