description: INTRODUCTION AND IMPORTANCE: Aneurysms of the carotid artery are rare and potentially a risk factor for developing neurological events. This case report describes the treatment of a giant saccular aneurysm of the right extracranial internal carotid artery (ICA) with adhesion to the vagus verve. CASE PRESENTATION: An 85 -year-old female presented with an asymptomatic pulsating mass on the right neck. Ultrasonography and MR angiography revealed a giant aneurysm of the right internal carotid artery with a massive tortuosity. Intraoperatively, a massive adhesion of the vagus nerve to the aneurysm was found. A resection of the aneurysm followed by a spatulated end -to -end anastomosis was performed. Postprocedural neurological symptoms included a transient paralysis of the vagus nerve that recovered within six weeks. CLINICAL DISCUSSION: The treatment options of ICA aneurysms include open surgical and endovascular interventions. Endovascular treatment may be a good option for aneurysms with a particular morphology. However, open surgery is the favorable option for immense ICA aneurysms with a tortuous anatomical path. CONCLUSION: Aneurysm resection with end -to -end anastomosis is a possible surgical option in the case of tortuous extracranial ICA aneurysms. Leaving parts of the aneurysmal wall prevented occurring persisting damage of the adhesive vagus nerve.

description: Perceptual history can exert pronounced effects on the contents of conscious experience: when confronted with completely ambiguous stimuli, perception does not waver at random between diverging stimulus interpretations but sticks with recent percepts for prolonged intervals. Here, we investigated the relevance of perceptual history in situations more similar to everyday experience, where sensory stimuli are usually not completely ambiguous. Using partially ambiguous visual stimuli, we found that the balance between past and present is not stable over time but slowly fluctuates between two opposing modes. For time periods of up to several minutes, perception was either largely determined by perceptual history or driven predominantly by disambiguating sensory evidence. Computational modeling suggested that the construction of unambiguous conscious experiences is modulated by slow fluctuations between internally and externally oriented modes of sensory processing.

description: Intestinal mucus plays important roles in protecting the epithelial surfaces against pathogens, supporting the colonization with commensal bacteria, maintaining an appropriate environment for digestion, as well as facilitating nutrient transport from the lumen to the underlying epithelium. The mucus layer in the poultry gut is produced and preserved by mucin-secreting goblet cells that rapidly develop and mature after hatch as a response to external stimuli including environmental factors, intestinal microbiota as well as dietary factors. The ontogenetic development of goblet cells affects the mucin composition and secretion, causing an alteration in the physicochemical properties of the mucus layer. The intestinal mucus prevents the invasion of pathogens to the epithelium by its antibacterial properties (e.g. β-defensin, lysozyme, avidin and IgA) and creates a physical barrier with the ability to protect the epithelium from pathogens. Mucosal barrier is the first line of innate defense in the gastrointestinal tract. This barrier has a selective permeability that allows small particles and nutrients passing through. The structural components and functional properties of mucins have been reviewed extensively in humans and rodents, but it seems to be neglected in poultry. This review discusses the impact of age on development of goblet cells and their mucus production with relevance for the functional characteristics of mucus layer and its protective mechanism in the chicken’s intestine. Dietary factors directly and indirectly (through modification of the gut bacteria and their metabolic activities) affect goblet cell proliferation and differentiation and can be used to manipulate mucosal integrity and dynamic. However, the mode of action and mechanisms behind these effects need to be studied further. As mucins resist to digestion processes, the sloughed mucins can be utilized by bacteria in the lower part of the gut and are considered as endogenous loss of protein and energy to animal. Hydrothermal processing of poultry feed may reduce this loss by reduction in mucus shedding into the lumen. Given the significance of this loss and the lack of precise data, this matter needs to be carefully investigated in the future and the nutritional strategies reducing this loss have to be defined better.

description: The deployment of DeepCore array significantly lowers IceCube's energy threshold to about 10 GeV and enhances the sensitivity of detecting neutrinos from annihilations and decays of light dark matter. To match this experimental development, we calculate the track event rate in DeepCore array due to neutrino flux produced by annihilations and decays of galactic dark matter. We also calculate the background event rate due to atmospheric neutrino flux for evaluating the sensitivity of DeepCore array to galactic dark matter signatures. Unlike previous approaches, which set the energy threshold for track events at around 50 GeV (this choice avoids the necessity of including oscillation effect in the estimation of atmospheric background event rate), we have set the energy threshold at 10 GeV to take the full advantage of DeepCore array. We compare our calculated sensitivity with those obtained by setting the threshold energy at 50 GeV. We conclude that our proposed threshold energy significantly improves the sensitivity of DeepCore array to the dark matter signature for $m_χ< 100$ GeV in the annihilation scenario and $m_χ<300$ GeV in the decay scenario.

description: Background: The smoking-paradox of a better outcome in ischemic stroke patients who smoke may be due to increased efficacy of thrombolysis. We investigated the effect of smoking on outcome following endovascular therapy (EVT) with mechanical thrombectomy alone versus in combination with intra-arterial (IA-) thrombolysis. Methods: The primary endpoint was defined by three-month modified Rankin Scale (mRS). We performed a generalized linear model and reported relative risks (RR) for smoking (adjustment for age, sex, hypertension, atrial fibrillation, stroke severity, time to EVT) in patient data stemming from the Virtual International Stroke Trials Archive-Endovascular database. Results: Among 1,497 patients, 740(49.4%) were randomized to EVT; among EVT patients, 524(35.0%) received mechanical thrombectomy alone and 216(14.4%) received it in combination with IA-thrombolysis. Smokers (N = 396) had lower mRS scores (mean 2.9 vs. 3.2; p = 0.02) and mortality rates (10% vs. 17.3%; p<0.001) in univariate analysis. In all patients and in patients treated with mechanical thrombectomy alone, smoking had no effect on outcome in regression analyses. In patients who received IA-thrombolysis (N = 216;14%), smoking had an adjusted RR of 1.65 for an mRS1 (95%CI 0.77-3.55). Treatment with IA-thrombolysis itself led to reduced RR for favorable outcome (adjusted RR 0.30); interaction analysis of IA-thrombolysis and smoking revealed that non-smokers with IA-thrombolysis had mRS ≤ 2 in 47 cases (30%, adjusted RR 0.53 [0.41-0.69]) while smokers with IA-thrombolysis had mRS ≤ 2 in 23 cases (38%, adjusted RR 0.61 [0.42-0.87]). Conclusions: Smokers had no clear clinical benefit from EVT that incorporates IA-thrombolysis.
Opportunistic Routing in Ad Hoc Networks: How many relays should there be? What rate should nodes use?

description: Opportunistic routing is a multi-hop routing scheme which allows for selection of the best immediately available relay. In blind opportunistic routing protocols, where transmitters blindly broadcast without knowledge of the surrounding nodes, two fundamental design parameters are the node transmission probability and the transmission spectral efficiency. In this paper these parameters are selected to maximize end-to-end performance, characterized by the product of transmitter density, hop distance and rate. Due to the intractability of the problem as stated, an approximation function is examined which proves reasonably accurate. Our results show how the above design parameters should be selected based on inherent system parameters such as the path loss exponent and the noise level.

description: We demonstrate and characterize interference between discrete photons emitted by two separate semiconductor quantum dot states in different samples excited by a pulsed laser. Their energies are tuned into resonance using strain. The photons have a total coalescence probability of 18.1% and the coincidence rate is below the classical limit. Post-selection of coincidences within a narrow time window increases the coalescence probability to 47%. The probabilities are reduced from unity because of dephasing and the postselection value is also reduced by the detector time response.

description: Introduction: Intimate Partner Violence (IPV) is linked to low engagement with HIV management services and adverse clinical outcomes, including poor ART adherence. In sub-Saharan Africa, studies on pregnant/postpartum women and transactional sex workers have produced divergent evidence regarding IPV's association with poor ART adherence. We investigate this association among a broad group of women. Methods: We sampled 408 HIV-positive women receiving free ART from different types of HIV clinics at government health facilities, assessing for IPV exposure by a current partner, ART adherence rate, and other factors that affect ART adherence (e.g. education, disclosure). ART adherence rates were measured using the Visual Analogue Scale (VAS); responses were dichotomised at a ≥ 95% cut-off. Multiple logistic regression models assessed the association between the independent variables and ART adherence. Results: The participants' mean age was 38.6 (range: 18-69 years). The majority had ever attended school (94%, n = 382), were in monogamous marriages (70%, n = 282), and had disclosed status to partners (94%, n = 380). Overall, 60% (n = 242) reported optimal ART adherence (≥ 95%) in the previous 30 days. The prevalence of IPV by the current partner was 76% (CI95 = 72-80%). Experiencing physical IPV (AOR 0.57, CI95: 0.34-0.94, p = .028), sexual IPV (AOR 0.50, CI95: 0.31-0.82, p = .005), or controlling behaviour (AOR 0.56, CI95: 0.34-0.94, p = .027) reduced the odds of achieving optimal adherence, while a higher education level and having an HIV-positive partner increased the odds. Conclusion: IPV is common and is associated with suboptimal ART adherence rates among a broad group of HIV-positive women. ART programs could consider incorporating basic IPV interventions into regular clinic services to identify, monitor and support exposed women, as they might be at risk of poor ART adherence. Still, there is need for more research on how IPV affects ART adherence.

description: We calculate the shot noise power in a junction of a network of Majorana bound states (MBS) with a normal metal. These Majorana bound states are on the border of alternative ferromagnetic and superconducting regions at the quantum spin Hall insulator edge. We analyze different realization of MBS networks including a few isolated ones or in a chain allowing for the limit of weak and strong tunneling. The conductance, as well as the shot noise are considerably stronger than those of a weakly coupled normal-superconduting junction, being a hallmark of the MBS. We find that the Fano factor is quantized $F=2$ when one MBS member of a pair is coupled to the lead, however if both MBS members are coupled $F$ is non-integer.

description: We propose a method to probe time dependent correlations of non trivial observables in many-body ultracold lattice gases. The scheme uses a quantum non-demolition matter-light interface, first, to map the observable of interest on the many body system into the light and, then, to store coherently such information into an external system acting as a quantum memory. Correlations of the observable at two (or more) instances of time are retrieved with a single final measurement that includes the readout of the quantum memory. Such method brings at reach the study of dynamics of many-body systems in and out of equilibrium by means of quantum memories in the field of quantum simulators.

description: Este número da Revista Medi@ções aborda uma temática emergente nas políticas educativas locais e na construção de parcerias entre escolas, famílias e comunidades. A promoção destas parcerias envolve desafios, vontades e uma melhor compreensão dos mecanismos que impactam na vida escolar das crianças e jovens. Escola e família constituem duas instituições sociais centrais hoje em dia. A sua relação, sempre em processo de reconfiguração, tende a delinear uma interface de base local. Assim, escolas, famílias e comunidades tecem entre si uma complexa rede de interações cuja resultante é influenciada pelos atores sociais envolvidos em cada processo, assim como pela relação de forças destes em cada momento. O elemento comum nesta relação triangular é constituído pela criança (ou jovem) enquanto, simultaneamente, aluno(a) na escola, filho(a) em casa e membro de uma comunidade. Este constitui um dos motivos pelos quais se torna fulcral que estes três vértices da relação não constituam mundos à parte, assim como que o primeiro grande beneficiário de uma boa relação seja precisamente a criança (ou jovem).

description: Instruments for radio astronomical observations have come a long way. While the first telescopes were based on very large dishes and 2-antenna interferometers, current instruments consist of dozens of steerable dishes, whereas future instruments will be even larger distributed sensor arrays with a hierarchy of phased array elements. For such arrays to provide meaningful output (images), accurate calibration is of critical importance. Calibration must solve for the unknown antenna gains and phases, as well as the unknown atmospheric and ionospheric disturbances. Future telescopes will have a large number of elements and a large field of view. In this case the parameters are strongly direction dependent, resulting in a large number of unknown parameters even if appropriately constrained physical or phenomenological descriptions are used. This makes calibration a daunting parameter estimation task, that is reviewed from a signal processing perspective in this article.

description: As Atividades Interculturais da Escola Superior de Educação de Setúbal eram um estágio de terreno que consistia na permanência de grupos de alunos em comunidades do distrito de Setúbal. Constituíam, à data da sua criação, em 1987, uma inovação pedagógica que procurava construir uma escola diferente, aberta às comunidades e “ao serviço da região”. Neste artigo descreve-se a evolução destas atividades e o seu desenvolvimento ligado a sucessivas inovações curriculares, bem como o seu funcionamento na prática, os seus objetivos e as aprendizagens que potenciava. De igual forma problematiza-se o seu desaparecimento aquando da restruturação curricular ocorrida em 2007 na sequência da implementação do Processo de Bolonha no ensino superior português.

description: Introduction: Acute kidney injury (AKI) is an important complication in COVID-19, but its precise etiology has not fully been elucidated. Insights into AKI mechanisms may be provided by analyzing the temporal associations of clinical parameters reflecting disease processes and AKI development. Methods: We performed an observational cohort study of 223 consecutive COVID-19 patients treated at 3 sites of a tertiary care referral center to describe the evolvement of severe AKI (Kidney Disease: Improving Global Outcomes stage 3) and identify conditions promoting its development. Descriptive statistics and explanatory multivariable Cox regression modeling with clinical parameters as time-varying covariates were used to identify risk factors of severe AKI. Results: Severe AKI developed in 70 of 223 patients (31%) with COVID-19, of which 95.7% required kidney replacement therapy. Patients with severe AKI were older, predominantly male, had more comorbidities, and displayed excess mortality. Severe AKI occurred exclusively in intensive care unit patients, and 97.3% of the patients developing severe AKI had respiratory failure. Mechanical ventilation, vasopressor therapy, and inflammatory markers (serum procalcitonin levels and leucocyte count) were independent time-varying risk factors of severe AKI. Increasing inflammatory markers displayed a close temporal association with the development of severe AKI. Sensitivity analysis on risk factors of AKI stage 2 and 3 combined confirmed these findings. Conclusion: Severe AKI in COVID-19 was tightly coupled with critical illness and systemic inflammation and was not observed in milder disease courses. These findings suggest that traditional systemic AKI mechanisms rather than kidney-specific processes contribute to severe AKI in COVID-19.

description: This article takes up the challenge of extending the classical Real Nullstellensatz of Dubois and Risler to left ideals in a *-algebra A. After introducing the notions of non-commutative zero sets and real ideals, we develop three themes related to our basic question: does an element p of A having zero set containing the intersection of zero sets of elements from a finite set S of A belong to the smallest real ideal containing S? Firstly, we construct some general theory which shows that if a canonical topological closure of certain objects are permitted, then the answer is yes, while at the purely algebraic level it is no. Secondly for every finite subset S of the free *-algebra R of polynomials in g indeterminates and their formal adjoints, we give an implementable algorithm which computes the smallest real ideal containing S and prove that the algorithm succeeds in a finite number of steps. Lastly we provide examples of noncommutative real ideals for which a purely algebraic non-commutative real Nullstellensatz holds. For instance, this includes the real (left) ideals generated by a finite sets S in the *-algebra of n by n matrices whose entries are polynomials in one-variable. Further, explicit sufficient conditions on a left ideal in R are given which cover all the examples of such ideals of which we are aware and significantly more.

description: Background Patients surviving critical illnesses, such as sepsis, often suffer from long-term complications. After discharge from hospital, most patients are treated in primary care. Little is known how general practitioners (GPs) perform critical illness aftercare and how it can be improved. Within a randomised controlled trial, an outreach training programme has been developed and applied. Objectives The aim of this study is to describe GPs' views and experiences of caring for postsepsis patients and of participating a specific outreach training. Design Semistructured qualitative interviews. Setting 14 primary care practices in the metropolitan area of Berlin, Germany. Participants 14 GPs who had participated in a structured sepsis aftercare programme in primary care. Results Themes identified in sepsis aftercare were: continuity of care and good relationship with patients, GP's experiences during their patient's critical illness and impact of persisting symptoms. An outreach education as part of the intervention was considered by the GPs to be acceptable, helpful to improve knowledge of the management of postintensive care complications and useful for sepsis aftercare in daily practice. Conclusions GPs provide continuity of care to patients surviving sepsis. Better communication at the intensive care unit-GP interface and training in management of long-term complications of sepsis may be helpful to improve sepsis aftercare.

description: La ricerca, si propone di mettere a disposizione un nuovo sguardo sulla figura della docente di Arti plastiche, consentendo di conoscere la grande complessità della materia e degli strumenti didattici a sua disposizione. Una lettura della materia caleidoscopica che agisce attraverso un’educazione che individua nel tema del fuori e del dentro, nel visibile e nell’invisibile, la dimensione privilegiata delle esperienze estetiche attive negli apprendimenti. Si vuole proporre una modalità di lavoro congeniale e simile alla istintiva capacità ricercatrice degli allievi. Il fuori cui si fa riferimento, consiste nella relazione con il mondo presente oltre la soglia della scuola, che educa e parla altri linguaggi. Un dialogo fra due contesti, scuola e mondo, teso fra valori che si intersecano, in tensione fra tradizione e rinnovamento e che, coerentemente con la loro modalità di apprendimento, propone attività ed esperienze didattiche in linea con quello che oggi sappiamo essere i modi in cui apprendono i bambini -molto simili a quelli della ricerca scientifica- innestandosi su interessi e attraverso le motivazioni. Il dentro va inteso anche come lettura di se stessi e del processo cognitivo e metacognitivo messo in atto attraverso il tipo di ragionamento e la risposta restituita a un determinato compito o evento.

description: Within an effective field theory method to general relativity, we calculate the fifth order post--Newtonian (5PN)Hamiltonian dynamics also for the tail terms, extending earlier work on the potential contributions, working inharmonic coordinates. Here we calculate independently all (local) 5PN contributions to the tail terms using thein--in formalism, on which we give a detailed account. The five expansion terms of the Hamiltonian in the effectiveone body (EOB) approach, $q_{82}, q_{63}, q_{44}, \bar{d_5}$ and $a_6$, can all be determined from the localcontributions to periastron advance $K^{\rm loc,h}(\hat{E},j)$, without further assumptions on the structure ofthe symmetric mass ratio, $\nu$, of $\chi_k$. The $O(\nu^2)$ contributions to the 5PN EOB parameters have beenunknown in part before. We perform comparisons of our analytic results with the literature and also presentnumerical results on some observables.

description: With increasing use of vagus nerve stimulation (VNS) as an adjunct treatment for drug-resistant epilepsy, revision surgery of VNS grows in importance. Indications for revision surgery are diverse and extend of surgery varies. We report a retrospective review on indications and complications of VNS revision surgery at our center. Of 90 VNS procedures 54.4% were revision surgeries. Among those the vast majority was due to depletion of the battery. The entire system was explanted in 15 patients, due to no beneficial effect detected (n = 4), due to irritating side effects (n = 4), and so further diagnostics could cbe carried out (n = 7). Interestingly in three of the patients who underwent further diagnostics, resective epilepsy surgery was performed. Surgical complications occurred in 8.2%. In our experience, revision surgery of VNS was a frequent and safe procedure. There is a need to carefully reviewthe initial indication for VNS implantation prior to revision surgery.
Il progetto culinario in classe di lingua straniera: una modalità efficace per lo sviluppo della competenza orale?

description: Il presente Lavoro di Diploma descrive un progetto culinario in classe di lingua straniera messo in atto durante le lezioni di francese in una classe di prima media. L’obiettivo era di creare delle video ricette di piatti tipici romandi in francese. Un progetto di questo tipo si inserisce nell’ottica moderna della didattica delle L2 e utilizza l’approccio basato sui compiti privilegiato dal QCRE. Il progetto si è svolto attraverso varie attività di preparazione in aula e in cucina dove gli allievi hanno cucinato le ricette presentandole in francese mentre venivano filmati. In modo da poter paragonare i risultati delle produzioni orali delle due classi eseguite in contesti diversi, le stesse attività si sono svolte nella classe-test con l’obiettivo di preparare la presentazione orale delle ricette in aula. Parallelamente, si è voluto osservare se un progetto di questo tipo può aiutare gli allievi nell’autovalutazione delle competenze. L’analisi dei risultati ha mostrato che il progetto culinario in francese ha un influsso positivo sullo sviluppo della competenza orale degli allievi. Il fatto di descrivere ciò che si sta effettivamente facendo rende l’espressione orale molto spontanea e aiuta la riattivazione del lessico e delle strutture linguistiche. I risultati indicano anche che il progetto culinario aiuta l’autovalutazione degli allievi: essi sono più critici e riflettono meglio su se stessi perché svolgono un compito concreto e vicino alla realtà.

description: In this paper, we explore the nucleation of vacuum bubbles in the Brans-Dicke type theory of gravity. In the Euclidean signature, we evaluate the fields at the vacuum bubbles as solutions of the Euler-Lagrange equations of motion as well as the bubble nucleation probabilities by integrating the Euclidean action. We illustrate three possible ways to obtain vacuum bubbles: true vacuum bubbles for ω>-3/2, false vacuum bubbles for ω-3/2 when the vacuum energy of the false vacuum in the potential of the Einstein frame is less than that of the true vacuum. After the bubble is nucleated at the t=0 surface, we can smoothly interpolate the field combinations to some solutions in the Lorentzian signature and consistently continue their subsequent evolutions. Therefore, we conclude that, in general scalar-tensor theories like this Brans-Dicke type theories, which may include and represent certain features of string theory, vacuum bubbles come in false vacuum bubbles as well as in true vacuum bubbles, as long as a special condition is assumed on the potential.

description: Genomic studies have provided insights into molecular subgroups and oncogenic drivers of pediatric brain tumors (PBT) that may lead to novel therapeutic strategies. Participants of the cohort Pediatric Brain Tumor Atlas: CBTTC (CBTTC cohort), were randomly divided into training and validation cohorts. In the training cohort, Kaplan-Meier analysis and univariate Cox regression model were applied to preliminary screening of prognostic genes. The LASSO Cox regression model was implemented to build a multi-gene signature, which was then validated in the validation and CBTTC cohorts through Kaplan-Meier, Cox, and receiver operating characteristic curve (ROC) analyses. Also, gene set enrichment analysis (GSEA) and immune infiltrating analyses were conducted to understand function annotation and the role of the signature in the tumor microenvironment. An eight-gene signature was built, which was examined by Kaplan-Meier analysis, revealing that a significant overall survival difference was seen, either in the training or validation cohorts. The eight-gene signature was further proven to be independent of other clinic-pathologic parameters via the Cox regression analyses. Moreover, ROC analysis demonstrated that this signature owned a better predictive power of PBT prognosis. Furthermore, GSEA and immune infiltrating analyses showed that the signature had close interactions with immune-related pathways and was closely related to CD8 T cells and monocytes in the tumor environment. Identifying the eight-gene signature (CBX7, JADE2, IGF2BP3, OR2W6P, PRAME, TICRR, KIF4A, and PIMREG) could accurately identify patients' prognosis and the signature had close interactions with the immunodominant tumor environment, which may provide insight into personalized prognosis prediction and new therapies for PBT patients.

description: The linear- and quadratic-in-spin contributions to the binding potential and gravitational-wave flux from binary systems are derived to next-to-next-to-leading order in the Post-Newtonian (PN) expansion of general relativity, including finite-size and tail effects. The calculation is carried out through the worldline effective field theory framework. We find agreement in the overlap with the available PN literature and test-body limit. As a direct application, we complete the knowledge of spin effects in the evolution of the orbital phase for aligned-spin circular orbits to fourth PN order. We estimate the impact of the new results in the number of accumulated gravitational-wave cycles. We find they will play an important role in providing reliable physical interpretation of gravitational-wave signals from spinning binaries with future detectors such as LISA and the Einstein Telescope.
