Vertical shear instability in two-moment radiation-hydrodynamical simulations of irradiated protoplanetary disks
Authors: Melon Fuksman Julio David , Flock Mario , Klahr Hubert 
Published: December 2023

Context. Hydrodynamical instabilities are likely the main source of turbulence in weakly ionized regions of protoplanetary disks. Among these, the vertical shear instability (VSI) stands out as a rather robust mechanism due to its few requirements to operate, namely a baroclinic stratification, which is enforced by the balance of stellar heating and radiative cooling, and short thermal relaxation timescales.
Aims. Our goal is to characterize the transport of angular momentum and the turbulent heating produced by the nonlinear evolution of the VSI in axisymmetric models of disks around T Tauri stars, considering varying degrees of depletion of small dust grains resulting from dust coagulation. We also explore the local applicability of both local and global VSI-stability criteria.
Methods. We modeled the gas-dust mixture in our disk models by means of high-resolution axisymmetric radiation-hydrodynamical simulations including stellar irradiation with frequency-dependent opacities. This is the first study of this instability to rely on two-moment radiative transfer methods. Not only are these able to handle transport in both the optically thin and thick limits, but also they can be integrated via implicit-explicit methods, thus avoiding the employment of expensive global matrix solvers. This is done at the cost of artificially reducing the speed of light, which, as we verified for this work, does not introduce unphysical phenomena.
Results. Given sufficient depletion of small grains (with a dust-to-gas mass ratio of 10% of our nominal value of 10−3 for < 0.25 μm grains), the VSI can operate in surface disk layers while being inactive close to the midplane, resulting in a suppression of the VSI body modes. The VSI reduces the initial vertical shear in bands of approximately uniform specific angular momentum, whose formation is likely favored by the enforced axisymmetry. Similarities with Reynolds stresses and angular momentum distributions in 3D simulations suggest that the VSI-induced angular momentum mixing in the radial direction may be predominantly axisymmetric. The stability regions in our models are well explained by local stability criteria, while the employment of global criteria is still justifiable up to a few scale heights above the midplane, at least as long as VSI modes are radially optically thin. Turbulent heating produces only marginal temperature increases of at most 0.1% and 0.01% in the nominal and dust-depleted models, respectively, peaking at a few (approximately three) scale heights above the midplane. We conclude that it is unlikely that the VSI can, in general, lead to any significant temperature increase since that would either require it to efficiently operate in largely optically thick disk regions or to produce larger levels of turbulence than predicted by models of passive irradiated disks.

Published: December 2023

Context. The Juno spacecraft has acquired exceptionally precise data on Jupiter’s gravity field, offering invaluable insights into Jupiter’s tidal response, interior structure, and dynamics, establishing crucial constraints.
Aims. We aim to develop a new model for calculating Jupiter’s tidal response based on its latest interior model, while also examining the significance of different dissipation processes for the evolution of its system. We studied the dissipation of dynamical tides in Jupiter by thermal, viscous, and molecular diffusivities acting on gravito-inertial waves in stably stratified zones and inertial waves in convection ones.
Methods. We solved the linearised equations for the equilibrium tide. Next, we computed the dynamical tides using linear hydrodynamical simulations based on a spectral method. The Coriolis force is fully taken into account, but the centrifugal effect is neglected. We studied the dynamical tides occurring in Jupiter using internal structure models that respect Juno’s constraints. We specifically looked at the dominant quadrupolar tidal components, and our focus is on the frequency range that corresponds to the tidal frequencies associated with Jupiter’s Galilean satellites.
Results. By incorporating the different dissipation mechanisms, we calculated the total dissipation and determined the imaginary part of the tidal Love number. We find a significant frequency dependence in dissipation spectra, indicating a strong relationship between dissipation and forcing frequency. Furthermore, our analysis reveals that, in the chosen parameter regime in which kinematic viscosity and thermal and molecular diffusivities are equal, the dominant mechanism contributing to dissipation is viscosity, exceeding both thermal and chemical dissipation in magnitude. We find that the presence of stably stratified zones plays an important role in explaining the high dissipation observed in Jupiter.

Background: Left ventricular assist device (LVAD) candidates are at increased risk of immune dysregulation and infectious complications. To attenuate the elevated proinflammatory cytokine levels and associated adverse clinical outcomes, it has been postulated that extracorporeal blood purification could improve the overall survival rate and morbidity of patients undergoing LVAD implantation. Methods: We retrospectively reviewed prospectively collected data of 15 patients who underwent LVAD implantation at our center between January 2021 and March 2022. Of these, 15 (100%) who received HeartMate 3™ (St. Jude Medical, Abbott, MN, USA) device were eligible. Intraoperatively, patients were single randomized 1:1:1 to three groups: group 1, patients who received Cytosorb therapy (n = 5; installed in the CPB circuit); group 2, patients who received Jafron HA330 (n = 5; installed in the CPB circuit); and control group 3, patients who did not receive filter (n = 5; usual care, neither Cytosorb nor Jafron during CPB). Baseline patient characteristics and intraoperative data were compared between the groups. Blood sample analyses were performed to assess the levels of inflammatory markers (IL-1, 6, 8; CRP, Leukocyte, Lactate, PCT, NT-proBNP, TNF-α) in both preoperative and postoperative data. Results: Baseline patient characteristics were similar in all three groups. We found that IL1α; IL 6; IL8; Lactatedehydrogenase, PCT, pro-BNP, CRP; Leukocyte, and TNFα levels significantly increased with LVAD implantation and that neither Cytosorb nor Jafron influenced this response. In-hospital mortality and overall survival during follow-up were similar among the groups. Conclusion: Our preliminary results showed that hemoadsorption therapy using Cytosorb or Jafron hemoadsorption (HA) 330 may not be clinically beneficial for patients with advanced heart failure undergoing LVAD implantation. Large prospective studies are needed to evaluate the potential role of HA therapy in improving outcomes in patients undergoing LVAD implantation.

Psychiatrie ohne Zwang
Authors: Theodoridou Anastasia , Jäger Matthias 
Published: December 2023

ZUSAMMENFASSUNGZwang in der Psychiatrie stellt ein anhaltendes Problem dar und wird national wie international kritisch diskutiert. Trotz aller Bemühungen gelang es bisher nicht, die Zahl der Zwangsmaßnahmen zufriedenstellend zu reduzieren. Die Gründe hierfürsind vielschichtig und komplex. Die gesellschaftlichen Entwicklungen fordern das psychiatrische Gesundheitssystem heraus und führen zu einer Zunahme der kontroversen Diskussion über die zugrunde liegenden medizinisch-psychiatrischen, ethischen und juristischen Annahmen und Überzeugungen. Angesichts des bestehenden Dilemmas diesbezüglich ist eine weitere Optimierung der Prävention und Reduktion von Zwangsmaßnahmen in der Psychiatrie dringend nötig. Die Neuordnung der Zuständigkeiten im Notfall kann in Kombination mit einer Strategie wie der vorgestellten „Zero-Coercion“-Initiative hierbei eine „Katalysatorfunktion“ übernehmen und die Entwicklung von Alternativstrategien ermöglichen, die in einer festgefahrenen Rollenverteilung nicht erkannt werden können.

Abstract
Background and study aims The utility of esophagogastroduodenoscopy (EGD) in the left lateral semi-recumbent position in the setting of acute upper gastrointestinal bleeding (UGIB) with a persistent fundal pool of blood for adequate visualization and effective endotherapy has not been studied. This study aimed to evaluate the feasibility, efficacy, and safety of this position in such settings.
Patients and methods A prospective study of patients presenting with acute UGIB with an uncleared fundal pool of blood was conducted. All underwent EGD in the left lateral decubitus and secondary left lateral semi-recumbent positions. Outcomes in secondary position in terms of adequate visualization of the fundus, identification of new or additional sources of bleeding, and effectiveness of endotherapy were studied.
Results We screened 860 patients and included 44 patients (5.11%) with a persistent fundal pool of blood. Endoscopy in the primary position revealed the source of bleeding in 37 of 44 patients (84%). The source of the bleeding was not identified in seven of 44 patients (16%). Endoscopy in the secondary position showed clearance of fundal pool in all 44 patients (100%). A new source of bleeding was identified in all seven patients (100%) and an additional source could be identified in another five patients (13.6%). Endotherapy was performed in the secondary position for all 44 patients with 100% technical success and 94% clinical success.
Conclusions These data show that endotherapy in the left lateral semi-recumbent position is feasible, safe, and effective. It should be done when endoscopy in the left lateral decubitus position reveals a pool of blood in the fundus and there is inadequate visualization of the fundus.

Abstract
Background and study aims Colorectal serrated lesions and polyps (SPs) include hyperplastic polyps (HP), sessile serrated lesions-/+dysplasia (SSL/SSL-D), and traditional serrated adenomas (TSA). From 20% to 30% of colorectal cancers (CRC) develop from SP. We present incidence and baseline characteristics of SP in a Danish cohort.
Patients and methods We used The Danish Pathology Registry to include all SPs in the Danish population from January 1, 2000 to December 31, 2021. Based on the unique Danish personal identification number and SNOMED-codes, combined with the age and sex of patients, and date of procedure, we determined the incidence of the SP subtypes, anatomical location, and changes over time.
Results During the period from 2000 to 2021, a total of 292,761 SPs were removed from 163,840 patients: 51,649 SSLs, 5959 SSL-Ds, 224,860 HDs, and 10,293 TSAs. The median age of patients was 64.1 years (range 55.2–71.6) and 53.3% were male. We found a general increase in SPs from 3525 in 2000 to 25,853 in 2021 and a rise in the SSL proportion from 1.7% in 2006 to 38% in 2021. Half of all patients had more than one lesion at endoscopy with conventional adenomas being the most common. CRC was found along with SPs in 3.3% of procedures, while 1% to 2.5% of the patients developed metachronous CRC.
Conclusions We found an increasing number of SPs, especially SSLs. From 2019 to 2021 the number of SPs seem to stabilize, while the proportion of SSLs keeps rising. Synchronous lesions were common along all subtypes of SP.
Masseter Vestibular-Evoked Myogenic Potential Result of Possible Meniere's Patients
Authors: Behmen Meliha B. , Konukseven Bahriye Ozlem , Tak Aysegul Y. 
Published: December 2023

Abstract
Background The masseter vestibular-evoked myogenic potential (mVEMP) test evaluates the vestibulomasseteric reflex neural pathway between the sound-stimulated saccule hair cells and the motor neurons of the trigeminal nerve.
Purpose This study aims to investigate the contribution of mVEMP to the conclusive diagnosis of recurrent vestibulopathy patients that were diagnosed with Possible Meniere's disease.
Methods The study includes 20 healthy individuals aged 18 to 40 years and 20 patients that were diagnosed with Possible Meniere's disease according to the American Academy of Otorhinolaryngology and Head and Neck Surgery (AAO–HNS, 1995) Guidelines for the Definition of Meniere's Disease. In addition to the AAO–HNS, 1995 criteria, the presence of aural signs on the affected side was questioned according to the Meniere's criteria updated in 2015. mVEMP records were obtained by using surface electrodes placed on masseter muscles. Latency and amplitude values and asymmetry ratios of mVEMP waves were used for statistical analysis.
Results Asymmetry ratios were 15.9 ± 9.7% for the control group and 60.61 ± 45.52 for the experimental group; this difference was statistically significant (p < 0.05). The absolute latency and amplitude results were not statistically different between groups (p > 0.05).
Conclusion As Murofushi et al. (2001) stated in the literature, cervical vestibular-evoked myogenic potential (VEMP)/ocular VEMP latencies were not affected in peripheral pathologies, and in our study, no difference was observed between the groups in mVEMP latencies. The findings of our study showed that asymmetry ratio and absence of waves should be used in the clinical evaluation of Possible Meniere's disease. We conclude that mVEMP can be used to determine the lateralization of vestibular disorders and to support the presence of a vestibular pathology. mVEMP can contribute to the vestibular test battery.

Abstract
Background and study aims Noninvasive ampullary neoplasms may be removed by surgery or endoscopy. However, given the morbidity and mortality associated with surgery, endoscopic papillectomy (EP) is the preferred approach. Radiofrequency ablation (RFA) after EP has emerged as a promising alternative therapy to avoid surgery after incomplete EP. Our goal was to evaluate the efficacy and safety of RFA for residual or recurrent lesions with intraductal extension after endoscopic papillectomy.
Patients and methods The inclusion criteria include clinical trials, cohort studies, and case series evaluating patients with residual or recurrent lesions with intraductal extension after EP treated with RFA. Case reports, duplicated data, and studies with follow-up periods < 10 months were excluded. The metanalysis evaluated adverse events, surgical conversion rate, clinical success and recurrence.
Results Seven studies were selected, totaling 124 patients. RFA was associated with a clinical success rate of 75.7% (95% confidence interval [CI] 65.0-88.0%; I2 = 23.484) in a mean follow-up period < 10 months. However, the biliary stricture rate was 22.2% (95% CI 12.1-28.4%; I2 = 61.030), 14.3% of pancreatitis (95% CI 8.8-22.3%; I2 < 0.001), 7.0% of cholangitis (95% CI 3.3-14.5%; I2 < 0.001), 4.0% of bleeding (95% CI 1.7-9.3%; I2 < 0.001), and recurrence of 24.3% (95% CI 16.0-35.0%; I2 = 23.484).
Conclusions RFA is feasible and appears to be effective for managing residual or recurrent lesions with intraductal extension after EP. However, long-term follow-up and high-quality studies are required to confirm our findings.

Abstract
Objective The aim of this study was to evaluate the surface roughness, contact angle, and adhesion of Candida albicans to computer-aided designing/computer-aided manufacturing (CAD/CAM) and heat-polymerized (HP) denture base materials.
Materials and Methods Specimens were allocated to six groups based on the composition of studied denture base materials, HP acrylic resin, milled resins (AvaDent and IvoCad), and 3D-printed resins (ASIGA, FormLabs, and NextDent). Ten specimens per group were used for each test (n = 10/test). Surface roughness and contact angles were analyzed using profilometer and goniometer, respectively. Adhesion of C. albicans was counted using colony-forming unit (CFU/mL). Means and standard deviations were calculated, and then one-way analysis of variance (ANOVA), followed by Tukey's post hoc test. Correlation of Candida adhesion and surface parameters was determined by using Pearson's correlation analysis.
Results No statistically significant difference was noted in surface roughness between HP, milled, and 3D-printed denture base resins except NextDent, which showed significantly higher roughness in comparison to all other resins (p = 0.001). In terms of contact angle, milled resins had the lowest value, followed by HP, ASIGA, and FormLabs, whereas NextDent showed the highest contact angle (p = 0.001). C. albicans adhesion showed no significant difference between all denture base resins. A positive and significant correlation was found between C. albicans adhesion and contact angle (p = 0.003), while no correlation was reported between C. albicans adhesion and surface roughness (p = 0.523).
Conclusion Adhesion of C. albicans was similar in all tested specimens. Surface roughness showed no significant difference between all groups except NextDent, which had the highest value. Milled denture base resins had the lowest contact angle among all groups.
New assignments of Raman spectra of tetrahedra and the effects of electronegativity. II. Silicate glasses
Authors: Bancroft G. Michael , Dean Philip A. W. , Henderson Grant S. , Nesbitt H. Wayne 
Published: December 2023

Our density functional theory calculations (by GAUSSIAN) on the Si4O104− moiety and Na4Si4O10 molecule reproduce the experimental Raman frequencies and relative intensities for the three A1 modes in the experimental Raman spectra of Na2Si2O5 and BaSi2O5 crystals and glasses. Taking the center of mass into consideration, accompanied by visualization using GaussView, these calculations provide a firm assignment of these three peaks: the 1060 cm−1 peak to the Si-NBO stretch (NBO = Si–O or Si–O–Na), the ∼600 cm−1 peak to the Si-BO stretch (BO = Si–O–Si), and the ∼500 cm−1 peak to the Si-BO-Si bend. Our GAUSSIAN calculations on modified “non-equilibrium” SiO44− tetrahedra, constrained to have the same Si–O bond lengths and O–Si–O bond angles as in the Si4O104− moiety, confirm the above-mentioned assignment and show reasonable agreement with the experimental Raman frequencies and relative intensities. We then examine the regular trends in the Si-NBO and Si-BO stretch frequencies for all Qn (n = 0–4) species in silicate glasses and crystals. The large systematic change in the differences between these frequencies (Δ1) is explained by electronic changes within the SiO4 tetrahedron. For example, the larger Δ1 for the Q3 tetrahedra than the Q2 tetrahedra is due to the changes in Si, BO, and NBO electron densities on the tetrahedral Si and O atoms, as measured by Si 2p and O 1s x-ray photoelectron spectra. This trend strongly suggests that the Si-BO stretch frequency for the Q4 species in v-SiO2 should be ∼500 cm−1, close to the A1 breathing mode frequency of 495 cm−1 for four membered rings previously assigned.
Malleable meaning
Authors: Montesi Vanessa 
Published: December 2023

AbstractThis paper examines the process of recontextualization of Hieronymus Bosch’s paintingThe Garden of Earthly Delights(1505–1515) as a dance performance choreographed by Compagnie Marie Chouinard and presented at the Centro Cultural de Belém (CCB) in 2018. It shows how both source and target texts have been interpreted by scholars and the public in relation to the discursive framings offered by the physical space of their location and their historical contexts. While the first alleged locations of the painting have led the art historiansStefan Fischer (2016)andHans Belting (2018)to relate it either to the traditional moral precepts of Christianity or to the new voyages of colonization, the location of Chouinard’s dance performance at the heart of the most visible inscription of Portuguese colonial past, the district of Belém, created a parallel friction with the moral interpretation offered by the CCB. In analyzing how the process of recontextualization can activate dissonant discursive frames, I propose recontextualization as the operation of exposing the source text’s ambiguities and foregrounding the malleability of meaning-material.
Heritage speaker pragmatics

Published: December 2023

Abstract
The current study investigated request production in Russian as a Heritage language (HL), with a special focus on
the role of cross-linguistic influence (CLI) of the majority societal language (here SL-Hebrew) and Age of Onset of Bilingualism
(AOB). Ninety-seven adult participants were recruited in four groups: three groups of Russian-Hebrew bilinguals with various AOBs
of SL-Hebrew – before the age of 5 (n = 32), between the ages of 5–13 (n = 20), after the age of
13 (n = 19) – and a control group of monolingual Russian speakers (n = 26). The study elicited
20 requests in formal and informal contexts through oral role-plays. The results indicate that heritage speakers acquire the
basics of prototypical Russian request strategies across various social contexts. The results also show effects of CLI and AOB in
the pragmatic competence of HL-speakers. When faced with linguistic difficulties to express requests, HL speakers resort to the
use of compensatory strategies leading to the creation of novel structures. These novel structures are a combination of
conventions that are characteristic of the Russian acquired in childhood and transfer from the dominant SL. The study makes an
important contribution to the understanding of HL pragmatic development by investigating the effects of CLI and AOB.
