description: Since the pioneering works of Jakobson and Benedicks & Carleson and others, it has been known that a positive measure set of quadratic maps admit invariant probability measures absolutely continuous with respect to Lebesgue. These measures allow one to statistically predict the asymptotic fate of Lebesgue almost every initial condition. Estimating fluctuations of empirical distributions before they settle to equilibrium requires a fairly good control over large parts of the phase space. We use the sub-exponential slow recurrence condition of Benedicks & Carleson to build induced Markov maps of arbitrarily small scale and associated towers, to which the absolutely continuous measures can be lifted. These various lifts together enable us to obtain a control of recurrence that is sufficient to establish a level 2 large deviation principle, for the absolutely continuous measures. This result encompasses dynamics far from equilibrium, and thus significantly extends presently known local large deviations results for quadratic maps.

description: Background: REG3α has been recently shown to be a highly accurate biomarker for graft-versus-host-disease (GvHD). Given the unmet need of such biomarkers in Crohn's disease (CD) and the similarities between CD and GvHD, we aimed at investigating the role of serum REG3α as a diagnostic and prognostic biomarker in CD patients undergoing autologous hemopoetic stem cell transplantation (HSCT) in the multicenter Autologous Stem Cell Transplantation International Crohn's Disease (ASTIC) trial and to compare it to C-reactive protein (CRP). Methods: Stored serum samples from the ASTIC trial were analyzed using a commercially available human PAP1 ELISA-kit to measure REG3α levels. CRP was available from prior analysis in the ASTIC trial. These levels were correlated with clinical and endoscopic disease activity as well as overall clinical and endoscopic outcome 1 year after autologous HSCT. Results: One hundred thirty two serum samples were available for analysis. The mean concentration of REG3α was 101.8 ng/ml (95% CI 22.6-258.3). No significant elevation of REG3α was found among patients with active disease compared to those in remission (106.3 vs. 91.4). Patients with moderate to severe endoscopic disease activity showed substantially, although not significantly elevated REG3α levels compared to those in remission (95.4 vs. 52.4, p = 0.052). Baseline serum REG3α levels of patients without clinical or endoscopic remission 1 year after HSCT were not elevated compared to those in remission (63.1 vs. 66.9, and 68.4 vs. 59.2, respectively). In contrast, CRP was significantly elevated in patients with active disease compared to patients in remission (14.1 vs. 6.0 mg/dl, p = 0.032). In addition, CRP was elevated, although not significantly, in patients with severe endoscopic disease compared to those in endoscopic remission (18.7 vs. 4.1, p = 0.062). Furthermore, baseline CRP was reduced in patients with clinical and endoscopic remission after HSCT compared to those without remission, although not significantly (8.8 vs. 21.4, n.s. and 8.1 vs. 12.4, n.s.). Conclusion: Given the divergent findings compared to GvHD, we conclude that serum REG3α is not an accurate diagnostic and predictive biomarker in CD patients undergoing HSCT. In contrast, CRP is a valuable biomarker in order to differentiate active disease from remission. However, CRP does not seem to be of prognostic value for HSCT outcome.

description: The paper deals with the non-parametric estimation in the regression with the multiplicative noise. Using the local polynomial fitting and the bayesian approach, we construct the minimax on isotropic Hölder class estimator. Next applying Lepski's method, we propose the estimator which is optimally adaptive over the collection of isotropic Hölder classes. To prove the optimality of the proposed procedure we establish, in particular, the exponential inequality for the deviation of locally bayesian estimator from the parameter to be estimated. These theoretical results are illustrated by simulation study.

description: Actinic keratosis (AK) or lesions of epidermal dysplasia occurring in skin chronically exposed to solar radiation is very prevalent in lighter skin persons, with chronic long-term sun exposure being the major risk factor. With an aging population it is expected that the prevalence of AK will further increase. AK can progress to nonmelanoma skin cancer (NMSC) and is a public health concern. Six leading dermatologists with expertise in AK and NMSC from Germany met to discuss the nature of the disease and the prevention and treatment strategies available to dermatologists today. While cosmetic sunscreen products form an essential element of sun protection strategies, they are not adequate when damage has already been inflicted. Newly developed products of the medical device category offer DNA repair function paired with high sun protection factor (SPF) UV protection. An adjuvant treatment algorithm for various risk levels of AK was developed. For patients with low and moderate risk, sunscreen only is recommended. For patient groups with high and very high risk, a very high photoprotection and photorepair action (DNA repair enzymes) in medical device products all year round is recommended.

description: Background: We recently identified galectin-3 (gal-3) as a new and strong fibroblast activator produced by colonic epithelial cells. Very little is known about the influence of gal-3 in inflammatory bowel disease. We, therefore, investigated the impact of gal-3 on dextran sodium sulfate (DSS)-induced colitis in a mouse model. Methods: Colonic lamina propria fibroblasts of healthy controls were used for co-incubation studies of gal-3 with gal-1, TGF-β1, IFNγ, IL-4 and IL-10. Acute and chronic DSS colitis was induced by 3% DSS in drinking water in female Balb/c mice weighing 20-22 g. Recombinant gal-3 was expressed by the pET vector system and used for a 5-day treatment in different concentrations intraperitoneally. The distal third of the colon was used for histologic analysis. Colonic cytokine expression was determined by quantitative RT-PCR. Results: In vitro, gal-3 induced IL-8 secretion was significantly reduced by co-incubation with IL-10 (5 ng/ml) and IL-4 (10 ng/ml). Acute DSS-induced colitis was ameliorated by gal-3 treatment as indicated by increased colonic length and reduced weight loss compared to that of controls. In acute and chronic colitis, gal-3 treatment resulted in a significant suppression of colonic IL-6. Conclusion: Gal-3 significantly reduces inflammation in acute and chronic DSS colitis in mice indicating a potential role in intestinal inflammation.

description: Web browsers have come a long way since their inception, evolving from a simple means of displaying text documents over the network to complex software stacks with advanced graphics and network capabilities. As personal computers grew in popularity, developers jumped at the opportunity to deploy cross-platform games with centralized management and a low barrier to entry. Simply going to the right address is now enough to start a game. From text-based to GPU-powered 3D games, browser gaming has evolved to become a strong alternative to traditional console and mobile-based gaming, targeting both casual and advanced gamers. Browser technology has also evolved to accommodate more demanding applications, sometimes even supplanting functions typically left to the operating system. Today, websites display rich, computationally intensive, hardware-accelerated graphics, allowing developers to build ever-more impressive applications and games.In this paper, we present the evolution of browser gaming and the technologies that enabled it, from the release of the first text-based games in the early 1990s to current open-world and game-engine-powered browser games. We discuss the societal impact of browser gaming and how it has allowed a new target audience to accessdigital gaming. Finally, we review the potential future evolution ofthe browser gaming industry.

description: Graph Neural Networks (GNNs) are a form of deep learning that enable a wide range of machine learning applications on graph-structured data. The learning of GNNs, however, is known to pose challenges for memory-constrained devices such as GPUs. In this paper, we study exact compression as a way to reduce the memory requirements of learning GNNs on large graphs. In particular, we adopt a formal approach to compression and propose a methodology that transforms GNN learning problems into provably equivalent compressed GNN learning problems. In a preliminary experimental evaluation, we give insights into the compression ratios that can be obtained on real-world graphs and apply our methodology to an existing GNN benchmark.

description: We study the beam energy dependence of equilibration process and space-time characteristics of participant and spectator matter. For this, we simulated the semi-central collisions of $^{40}Ca+ ^{40}Ca$ at incident energies of 400, 600 and 1000 AMeV within the \emph{quantum molecular dynamics} (QMD) approach. Our numerical calculations based on the molecular dynamics approach show that incident energy of the projectile influences the reaction observables drastically. The effect is more visible for transverse expansion of the nuclear matter and transparency behavior. The degree of thermalization of participant matter, however, remains independent of the incident energy. The characteristics of the trajectories followed by the nucleons suffering maximal and minimal binary collisions are also analyzed.

description: We analyze the emission and absorption lines during photospheric radius expansion (PRE) X-ray bursts from the ultracompact binary 4U 1820--30, observed with the Neutron Star Interior Composition Explorer (NICER). Using Monte Carlo simulations to estimate the significance, we identified a 1 keV emission line from 14 bursts, a 3 keV absorption line from 12 bursts, and 1.6 keV absorption from one burst. By coadding the burst spectra at the maximum radius phase, we detected a 1.034 keV emission line with significance of $14.2σ$, and absorption lines at 1.64 and 3 keV with significances of $10.8σ$ and $11.7σ$, respectively. The observed energy shifts are consistent with the prediction from the burst-driven wind model, indicating that all three spectral features are produced by the PRE wind. Analysis of the ratios between the emission and absorption line energies suggests that the 1 keV feature is a superposition of several narrower Fe L-shell lines. To evaluate the scientific capabilities of the Hot Universe Baryon Surveyor (HUBS), we simulated mock observations of multiple narrow lines near 1 keV. The results demonstrate that HUBS is well suited for detailed studies of the 1 keV emission line during bursts, offering significant potential to advance our understanding of these phenomena.

description: In semi-inclusive deep inelastic scattering of polarized leptons on a transversely polarized target eight target transverse spin-dependent azimuthal modulations are allowed. In the QCD parton model half of these asymmetries can be interpreted within the leading order approach and the other four are twist-three contributions. The first two leading twist asymmetries extracted by HERMES and COMPASS experiments are related: one to the transversity distribution and the Collins effect, the other to the Sivers distribution function. These results triggered a lot of interest in the past few years and allowed the first extractions of the transversity and the Sivers distribution functions of nucleon. The remaining six asymmetries were obtained by the COMPASS experiment using a 160 GeV/c longitudinally polarized muon beam and transversely polarized deuteron and proton targets. Here we review preliminary results from COMPASS proton data of 2007.

description: Progress in Embodied AI has made it possible for end-to-end-trained agents to navigate in photo-realistic environments with high-level reasoning and zero-shot or language-conditioned behavior, but benchmarks are still dominated by simulation. In this work, we focus on the fine-grained behavior of fast-moving real robots and present a large-scale experimental study involving \numepisodes{} navigation episodes in a real environment with a physical robot, where we analyze the type of reasoning emerging from end-to-end training. In particular, we study the presence of realistic dynamics which the agent learned for open-loop forecasting, and their interplay with sensing. We analyze the way the agent uses latent memory to hold elements of the scene structure and information gathered during exploration. We probe the planning capabilities of the agent, and find in its memory evidence for somewhat precise plans over a limited horizon. Furthermore, we show in a post-hoc analysis that the value function learned by the agent relates to long-term planning. Put together, our experiments paint a new picture on how using tools from computer vision and sequential decision making have led to new capabilities in robotics and control.

description: Purpose The aim of this study was to identify general advantages and disadvantages of the flattening filter free irradiation mode in normo-fractionated intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT). Methods Various studies have been performed at our department to identify specific advantages and disadvantages of the use of the flattening filter free irradiation mode for the normo-fractionated treatment of different tumor sites. Volumetric modulated arc therapy (VMAT) and intensity modulated radiation therapy (IMRT) plans were created with and without flattening filter for at least 10 patients for each tumor site. All treatment plans were verified by a 2D-ionization-chamber-array and delivery times were measured from first beam on to last beam off. Peripheral doses were determined with an ionization chamber as a measure of radiation induced second cancer risk. Differences were evaluated in terms of plan quality, irradiation time, and radiation induced second cancer risk. The results of these studies were reviewed to assess general advantages or disadvantages independent on the specific tumor entity or treatment technique. Results Differences in plan quality and irradiation time were dependent on the tumor entity and treatment technique. The peripheral dose as a measure of radiation induced second cancer risk, however, was significantly reduced in the flattening filter free mode for all tumor sites and treatment techniques. The reduction ranged from 17% to 33%. Conclusion The only general advantage of the flattening filter free irradiation mode observed for all tumor sites and treatment techniques was a reduction in dose to peripheral organs corresponding to a reduction in radiation induced second cancer risk in these organs. No general advantage or disadvantage could be observed in terms of plan quality or treatment time.

description: BE Cet is a young solar analog with an age of 0.6 Gyr and a rotation period of 7.655 days. According to chromospheric and photospheric indices, its activity is higher than the solar one. An analysis of photometric data on the time interval between 1977 and 2019 shows the presence of only 6.76 yr cyclic variations in the mean brightness with an amplitude of 0.02 mag. The obtained cycle is 1-2 yr shorter in comparison with the chromospheric cycle determined earlier, whose length was estimated to be 9 or 7.6 yr. Parameters of the cycle, its amplitude and duration change slightly in different epochs. The short-term light variations due to rotational modulation occur with an increase in amplitude up to 0.05 mag near the activity cycle minimum and a decrease in its maximum. Some events of a rapid increase in brightness of 0.2-0.6 mag may be considered as flares.

description: Background: A pilot study of an 8-week mindfulness-based stress reduction (MBSR) program on a sample of low back pain patients was conducted in order to assess the feasibility and effectiveness of the intervention as well as changes in an EEG pattern called thalamocortical dysrhythmia which is associated with chronic pain. Patients and Methods: 22 patients with chronic low back pain participated in an MBSR program. Effect sizes were measured for psychological functioning, pain severity, and quality of life. Furthermore, 4 parameters of the EEG power spectral density were assessed. Results: Medium size effect sizes were found for health-related quality of life (EQ-5D, VAS, d = 0.43, p = 0.02; SF-12, psychological functioning, d = 0.50, p = 0.05), health-related life satisfaction (questions on life satisfaction d = 0.69, p = 0.01), depression (HADS, d = 0.48, p = 0.04, Brief Symptom Inventory d = 0.41, p = 0.04), and affective pain perception (pain perception scale d = 0.50, p = 0.04). The most relevant pain severity measurements improved in the range of d = 0.45-0.75 (p = 0.01-0.24). EEG analyses revealed no differences between the pre- and post-intervention. Conclusion: MBSR is a feasible intervention for patients with low back pain. They benefit from medium size effects which are comparable to similar behavioral interventions. Randomized controlled trials are needed in order to determine the specificity of these benefits.
Creating memorable tasting room experience : service provider perspectives

description: Wine tours and wine tastings are important components of the Okanagan tourism industry. For wineries to survive in today’s increasingly competitive market, they need to satisfy not only the basic needs of consumers but also provide memorable experiences that “engage [consumers] on an emotional, physical, intellectual or even spiritual level” (Pine and Gilmore, 1998, p. 99). Providing the right type of experience with products, services, and accompanying marketing programs has become acutely important (Kotler, Bowen, and Makens, 2014). Despite the widespread focus on and acknowledgment of the importance of memorable experiences, there is limited research on what exactly makes certain experiences special, extraordinary, and memorable. Furthermore, most consumer experience-related research has been conducted using quantitative approaches. In contrast, this study used a qualitative approach (Belk, 2006) to enhance previous findings on the factors required to facilitate memorable tourism experiences by exploring memorable consumption experiences in the wine context. Unpacking memorable consumer experiences in the wine context is critical to the success of wineries. Moreover, this process enables researchers and industry professionals to identify the various components of experiences and how they serve to transform consumers (Joy and Sherry, 2003). There are many wine consumer-related studies that focus on understanding visitors as wine buyers (Bruwer, 2004); however, the aim of this thesis is to provide a qualitative measure of the wine tasting experience from the service provider’s perspective to examine critical success factors for the development and management of consumer tasting experiences. In order to reach this goal, ethnographic data was collected using a combination of twelve in-depth expert interviews and participant observations at several wineries that focused on planning, delivery, and continued innovation of memorable experiences from the service provider’s perspectives. These findings suggest that ‘people’ and ‘process’ are the most important marketing mix elements that contribute to memorable tasting room experiences for the general public. In addition, the study found that consumption experience is co-produced by customers and service providers. Together, service providers and customers were found to play a critical role in providing memorable tasting room experiences through the process of customization.

description: We study resistivity temperature dependence of a three dimensional metamagnet near the metamagnet phase transition point in the case when magnetic structure tends to split into regions with high and low magnetization. We show that in the case of weak pinning the spin relaxation time of domain wall is much larger than that of the volume spin fluctuations. This opens a temperature range where resistivity temperature dependence is determined by scattering of conducting electrons by the domain wall fluctuations. We show that it leads to quasi-linear low temperature dependence of resistivity.

description: 3D point cloud semantic segmentation is one of the fundamental tasks for environmental understanding. Although significant progress has been made in recent years, the performance of classes with few examples or few points is still far from satisfactory. In this paper, we propose a novel multi-to-single knowledge distillation framework for the 3D point cloud semantic segmentation task to boost the performance of those hard classes. Instead of fusing all the points of multi-scans directly, only the instances that belong to the previously defined hard classes are fused. To effectively and sufficiently distill valuable knowledge from multi-scans, we leverage a multilevel distillation framework, i.e., feature representation distillation, logit distillation, and affinity distillation. We further develop a novel instance-aware affinity distillation algorithm for capturing high-level structural knowledge to enhance the distillation efficacy for hard classes. Finally, we conduct experiments on the SemanticKITTI dataset, and the results on both the validation and test sets demonstrate that our method yields substantial improvements compared with the baseline method.

Potential Benefit of Selective CMV Testing after Failed Newborn Hearing Screening

description: Evidence-based guidelines for the prevention, diagnosis and treatment of congenital cytomegalovirus (cCMV) were recently released by two independent expert groups. Of particular emphasis was the relationship between cCMV and sensorineural hearing loss (SNHL), a major component of the virus’ overall disease burden. In this study, a literature review was performed to estimate the proportion of cCMV-related SNHL cases, which might be identified through selective cCMV testing following failed newborn hearing screening. Furthermore, it was of interest to estimate the potential benefit of emerging antiviral therapies. Currently, at most 10% of cCMV-related SNHL is likely to be identified clinically. Through use of a selective cCMV testing protocol, however, a significant improvement in the identification rate can be achieved. Recent expert group statements strongly recommend antiviral therapy in cases of moderate-to-severe disease, especially in the presence of central nervous system involvement. Though differences exist between recommendations in instances of isolated SNHL or SNHL in combination with only mild symptoms, the majority of experts in both groups offered at least a weak recommendation for antiviral treatment. Available results suggest antiviral treatment could therefore benefit a meaningful proportion of newborns referred for cCMV testing following failed newborn hearing screening.

description: In this paper we discuss the question how matter may emerge from space. For that purpose we consider the smoothness structure of spacetime as underlying structure for a geometrical model of matter. For a large class of compact 4-manifolds, the elliptic surfaces, one is able to apply the knot surgery of Fintushel and Stern to change the smoothness structure. The influence of this surgery to the Einstein-Hilbert action is discussed. Using the Weierstrass representation, we are able to show that the knotted torus used in knot surgery is represented by a spinor fulfilling the Dirac equation and leading to a mass-less Dirac term in the Einstein-Hilbert action. For sufficient complicated links and knots, there are "connecting tubes" (graph manifolds, torus bundles) which introduce an action term of a gauge field. Both terms are genuinely geometrical and characterized by the mean curvature of the components. We also discuss the gauge group of the theory to be U(1)xSU(2)xSU(3).

description: This document describes the output of Task 4.1 of the SSHOC (Social Sciences and Humanities Open Cloud) project funded by the European Commission under Grant Agreement N° 823782. A technical infrastructure called Web Panel Sample Service (WPSS) has been implemented following the specifications published in November 2919 as deliverable 4.11 "A sample management system for cross- national web survey". This WPSS technical infrastructure is aimed at supporting large-scale, high quality cross-national multi- language web surveys. It provides a centralised management of survey fielding orchestration (publishing surveys, sending survey invites and reminders, fieldwork monitoring), and a decentralised and privacy- compliant handling of panellists’ data. This document outlines the twofold infrastructure that has been implemented, a Python2 / Django3 web application paired with a Qualtrics survey platform license. WPSS interacts through the API provided by Qualtrics4 to a dedicated and tailored Qualtrics License. After presenting the user roles involved either in the study coordination, sample management, messages and questionnaire editors and translators, the document presents the platform (WPSS or Qualtrics) each role is granted access to, and the actions available. Last, the document describes the relations between the 4.2 deliverable and the CRONOS-2 project led by ESS ERIC (funded by the European Commission under Grant Agreement ESS-SUSTAIN-2 N°871063); a WPSS instance dedicated to the first use case of the D4.2 "a ready to use sample management system" deliverable, the "Opinion survey for " survey.
Making way : DramaWay's history, artistic praxis and contribution to Canadian disability theatre
Creators: name: Gold, Rebecca (Becky)
Publisher: name: University of British Columbia

description: This is a study of DramaWay – a Toronto-based company that facilitates creative arts programming for individuals with special needs. Founded in 1999, this company has grown and developed to provide a sought after service for the disability community in the Greater Toronto Area (GTA). While there are other companies in Canada providing similar opportunities, I interrogate DramaWay’s distinctive approach within the broader context. More particularly, I investigate how DramaWay’s praxis contributes to the continuing development of disability theatre in Canada. Their work, I argue, merits more scholarly and critical attention than they have thus far garnered in the broader literature concerning disability performance in Canada and abroad. In this thesis I build from the insights of this broader scholarly field to provide an in-depth analysis of DramaWay’s history, artistic praxis and current educational infrastructure. Through my examination of archival materials, as well as information gathered through formal interviews with DramaWay’s artistic director, staff, volunteers and performers, I conclude that DramaWay’s praxis in presenting the talent of performers with special needs provides a unique and valuable contribution to disability theatre in Canada.

description: Orthogonal multi-user multiple-input multiple-output (MU-MIMO) channels allow for optimum performance with simplified precoding/equalization, and they achieve maximum multiplexing gain which is shared fairly among users. Reconfigurable intelligent surface (RIS) constitutes a promising cost-efficient solution to improve the wireless channel, since they consist of passive reflecting elements able to adjust the phases of the incoming waves. However, it is still widely unclear how these surfaces can improve spatial-multiplexing. In fact, the common RIS model cannot achieve perfect orthogonalization of MU-MIMO channels with a reasonable number of elements. Furthermore, efficient channel estimation algorithms for RIS, which are key for taking advantage of its benefits, are still a matter of research. We study two types of reconfigurable surfaces (RSs), namely amplitude-reconfigurable intelligent surface (ARIS) and fully-reconfigurable intelligent surface (FRIS), with extended capabilities over RIS. We show how these RSs allow for perfect channel orthogonalization, and, by minimizing the applied power, we show that they can potentially be implemented without the need of amplification. We also present an efficient channel estimation method for each of them that allows the base station (BS) to select the desired propagation channel.

description: Background: Limited, outdated, and poor quality data are available on the prevalence of tinnitus, particularly in Italy. Methods: A face-to-face survey was conducted in 2014 on 2,952 individuals, who represented the Italian population aged 18 or more (50.6 million). Any tinnitus was defined as the presence of ringing or buzzing in the ears lasting for at least 5 min in the previous 12 months. Results: Any tinnitus was reported by 6.2% of Italian adults, chronic tinnitus (i.e. for more than 3 months) by 4.8%, and severe tinnitus (i.e. which constitutes a big or very big problem) by 1.2%. The corresponding estimates for the population aged ≥45 years were 8.7, 7.4 and 2.0%, respectively. Multivariable analysis on population aged ≥45 years revealed that old age (odds ratio (OR) = 4.49 for ≥75 vs. 45-54 years) and obesity (OR = 2.14 compared to normal weight) were directly related to any tinnitus, and high monthly family income (OR = 0.50) and moderate alcohol consumption (OR = 0.59 for <7 drinks/week vs. non-drinking) were inversely related. Conclusions: This is the first study on tinnitus prevalence among the general Italian adult population. It indicates that in Italy tinnitus affects more than 3 million adults and is felt as a major problem by more than 600,000 Italians, mostly aged 45 years or more.

description: We present theoretical and experimental results on spatial quantum correlations induced by multiple scattering of nonclassical light. A continuous mode quantum theory is derived that enables determining the spatial quantum correlation function from the fluctuations of the total transmittance and reflectance. Utilizing frequency-resolved quantum noise measurements, we observe that the strength of the spatial quantum correlation function can be controlled by changing the quantum state of an incident bright squeezed-light source. Our results are found to be in excellent agreement with the developed theory and form a basis for future research on, e.g., quantum interference of multiple quantum states in a multiple scattering medium.

Higher derivative corrections in holographic Zamolodchikov-Polchinski theorem

description: We study higher derivative corrections in holographic dual of Zamolodchikov-Polchinski theorem that states the equivalence between scale invariance and conformal invariance in unitary d-dimensional Poincare invariant field theories. From the dual holographic perspective, we find that a sufficient condition to show the holographic theorem is the generalized strict null energy condition of the matter sector in effective (d+1)-dimensional gravitational theory. The same condition has appeared in the holographic dual of the "c-theorem" and our theorem suggests a deep connection between the two, which was manifested in two-dimensional field theoretic proof of the both.

description: More recently, immunotherapy has emerged as a novel potentially effective therapeutic option also for solid malignancies such as breast cancer (BC). Relevant approaches, however, are determined by the 2 main elements of cancer immunoediting - the elimination of nascent transformed cells by immunosurveillance on the one hand and tumor immune escape on the other hand. Correspondingly, we here review the role of the various cellular immune players within the host-protective system and dissect the mechanisms of immune evasion leading to tumor progression. If the immune balance of disseminated BC cell dormancy (equilibrium phase) is lost, distant metastatic relapse may occur. The relevant cellular antitumor responses and translational immunotherapeutic options will also be discussed in terms of clinical benefit and future directions in BC management.
Ground state of composite bosons in low-dimensional graphs

description: We consider a system of composite bosons given by strongly bound fermion pairs tunneling through sites that form a low-dimensional network. It has been shown that the ground state of this system can have condensate-like properties in the very dilute regime for two-dimensional lattices but displays fermionization for one-dimensional lattices. Studying graphs with fractal dimensions, we explore intermediate situations between these two cases and observe a correlation between increasing dimension and increasing condensate-like character. However, this is only the case for graphs for which the average path length grows with power smaller than 1 in the number of sites, and which have an unbounded circuit rank. We thus conjecture that these two conditions are relevant for condensation of composite bosons in arbitrary networks, and should be considered jointly with the well-established criterion of high entanglement between constituents.
