Relativistic fluids, hydrodynamic frames and their Galilean versus Carrollian avatars

Published: September 2022

Abstract
We comprehensively study Galilean and Carrollian hydrodynamics on arbitrary backgrounds, in the presence of a matter/charge conserved current. For this purpose, we follow two distinct and complementary paths. The first is based on local invariance, be it Galilean or Carrollian diffeomorphism invariance, possibly accompanied by Weyl invariance. The second consists in analyzing the relativistic fluid equations at large or small speed of light, after choosing an adapted gauge, Arnowitt-Deser-Misner-Zermelo for the former and Papapetrou-Randers for the latter. Unsurprisingly, the results agree, but the second approach is superior as it effortlessly captures more elaborate situations with multiple degrees of freedom. It furthermore allows to investigate the fate of hydrodynamic-frame invariance in the two limits at hand, and conclude that its breaking (in the Galilean) or its preservation (in the Carrollian) are fragile consequences of the behaviour of transport attributes at large or small c. Both methods do also agree on the doom of Nœtherian currents generated in the relativistic theory by isometries: conserved currents are not always guaranteed in Newton-Cartan or Carroll spacetimes as a consequence of Galilean or Carrollian isometries. Comparison of Galilean and Carrollian fluid equations exhibits a striking but often superficial resemblance, which we comment in relation to black-hole horizon dynamics, awkwardly akin to Navier-Stokes equations. This congruity is authentic in one instance though and turns out then to describe Aristotelian dynamics, which is the last item in our agenda.

Abstract
Leptonic signatures of Dark Matter (DM) are one of the cleanest ways to discover such a secluded form of matter at high energy colliders. We explore the full parameter space relevant to multi-lepton (2- and 3-lepton) signatures at the Large Hadron Collider (LHC) from representative minimal consistent models with scalar and fermion DM. In our analysis, we suggest a new parametrisation of the model parameter spaces in terms of the DM mass and mass differences between DM and its multiplet partners. This parametrisation allows us to explore properties of DM models in their whole parameter space. This approach is generic and quite model-independent since the mass differences are related to the couplings of the DM to the Standard Model (SM) sector. We establish the most up-to-date LHC limits on the inert 2-Higgs Doublet Model (i2HDM) and Minimal Fermion DM (MFDM) model parameter spaces, by using the complementary information stemming from 2- and 3-lepton signatures. We provide a map of LHC efficiencies and cross-section limits for such 2- and 3-lepton signatures allowing one to easily make model-independent reinterpretations of LHC results for analogous classes of models. We also present combined constraints from the LHC, DM relic density and direct search experiments indicating the current status of the i2HDM and MFDM model.

AbstractBackgroundERAS guidelines have provided an effective recovery approach for esophagectomy. This study aimed to identify the relationship between the length of hospital stay (LOS) and compliance with clinical benchmarks of an established institutional ERAS program.MethodsA single‐center prospective database of esophageal cancer patients was retrospectively analyzed between January 2016 and January 2020. All patients underwent surgery within a standardized ERAS pathway for esophagectomy. Compliance with individual ERAS benchmarks and postoperative outcomes were evaluated according to patient's LOS; accelerated (≤ 6 days, AR), targeted (7–8 days, TR), and delayed recovery (≥ 9 days, DR).ResultsThe study included 100 consecutive patients undergoing esophagectomy with a median LOS of 7 (3.8–40.8) days, and a 30‐day readmission rate of 12.6%. LOS was not affected by comorbidities, tumor type or stage, neoadjuvant therapy, operative approach or anastomotic leak. Postoperative complications were 49.5%, and 90‐day mortality was 3.8%. AR, TR, and DL were achieved by 45%, 31%, and 24% of patients, respectively. Postoperative morbidity differed significantly among groups, impacting LOS (p < 0.001). Overall compliance with ERAS protocol was 82.7% and adherence to specific benchmarks was initially (< 48 h) high, but significantly affected by postoperative complications afterwards.ConclusionsAdherence to recovery benchmarks in patients undergoing esophagectomy is most commonly impacted by postoperative complications. In esophageal cancer surgery, the adherence to ERAS benchmarks after esophagectomy should be regularly audited. Modification to ERAS protocols to increase application in patients with complications should be considered.
Abdominal fascia dehiscence: is there a connection to a special microbial spectrum?

Abstract
Introduction
Acute fascia dehiscence (FD) is a threatening complication occurring in 0.4–3.5% of cases after abdominal surgery. Prolonged hospital stay, increased mortality and increased rate of incisional hernias could be following consequences. Several risk factors are controversially discussed. Even though surgical infection is a known, indisputable risk factor, it is still not proven if a special spectrum of pathogens is responsible. In this study, we investigated if a specific spectrum of microbial pathogens is associated with FD.

Methods
We performed a retrospective matched pair analysis of 53 consecutive patients with an FD after abdominal surgery in 2010–2016. Matching criteria were gender, age, primary procedure and surgeon. The primary endpoint was the frequency of pathogens detected intraoperatively, the secondary endpoint was the occurrence of risk factors in patients with (FD) and without (nFD) FD.

Results
Intraabdominal pathogens were detected more often in the FD group (p = 0.039), with a higher number of Gram-positive pathogens. Enterococci were the most common pathogen (p = 0.002), not covered in 73% (FD group) compared to 22% (nFD group) by the given antibiotic therapy. Multivariable analysis showed detection of Gram-positive pathogens, detection of enterococci in primary laparotomy beside chronic lung disease, surgical site infections and continuous steroid therapy as independent risk factors.

Conclusion
Risk factors are factors that reduce wound healing or increase intra-abdominal pressure. Furthermore detection of Gram-positive pathogens especially enterococci was detected as an independent risk factor and its empirical coverage could be advantageous for high-risk patients.
Methodology to Analyse Three-Dimensional Asymmetries in the Forces Applied to the Pedals in Cycling

Published: September 2022

AbstractThe asymmetries study between both legs of the forces applied to the pedals in cycling is important because they may affect the performance of the cyclist or prevent the occurrence of injuries. Studies focused on analysing asymmetries in forces tend to consider only the effective force, disregarding the three-dimensional nature of the force. Furthermore, these studies do not analyse the possible physical or neurological causes that may have led to the appearance of the asymmetries. This paper presents a methodology to carry out three-dimensional analysis of the asymmetries of the forces applied in both pedals and discriminate the possible sources of these asymmetries. Seven participants, amateurs and without pathologies, were analysed. Two commercial pedals were instrumented to measure the three components of the force applied to each pedal. The Normalized Symmetry Index (NSI) and the Cross Correlation Coefficient (CCC) were used for the asymmetries analysis. Results showed that both indexes need to be used in conjunction to analyse the causes of asymmetry in the pedal forces from a 3D perspective along the pedal cycle. The NSI is an index that makes it possible to evaluate asymmetry by considering only the value of the force applied by each leg at each instant. The CCC makes it possible to evaluate whether the temporal evolutions of the forces applied by each leg are similar. Preliminary results suggest that the proposed methodology is effective for analysing asymmetries in the forces in a pedalling cycle from a three-dimensional point of view. Forces in the sagittal plane showed a high level of symmetry. The lateral-medial force presented the highest level of asymmetry due to the difference in the magnitudes of the applied forces by both legs and the existing time shift between the two force patterns. The results of this work will allow for more complete and accurate three-dimensional dynamic analyses of the lower body during pedalling.
A blockchain-based IoT data marketplace

Published: September 2022

AbstractThe (IoT) is growing steadily, and so is the number of data that is generated by (IoT) devices. This makes it difficult to find and leverage relevant data (and data sources) without a data marketplace. Such a marketplace provides a platform to enable different parties, e.g., sensor operators and service providers, to trade their data. Today, most data marketplaces are based on centralized solutions, which may become a single point of failure and come with expensive infrastructure, trust problems, and privacy issues. Therefore, we propose the application of blockchain technology to implement a data marketplace for the IoT. Within the proposed marketplace, smart contracts are used to implement various functionalities and enforce the rules of the data exchange. The marketplace also includes a proxy, a broker, and (GUIs) to enable data trading. To show the applicability of the proposed data marketplace, we analyze the costs arising from the utilization of smart contracts.
Autism Traits and Cognitive Performance: Mediating Roles of Sleep Disturbance, Anxiety and Depression
Authors: McArthur Gaynor E. , Lee Eunro , Laycock Robin 
Published: September 2022

AbstractTheories about autism spectrum disorder (ASD) have addressed cognitive deficits however few have examined how comorbid diagnoses, including sleep disturbance, anxiety and depression contribute to the underlying deficits. We investigated potential mediations of common ASD comorbidities in the relationship between sub-clinical autism traits and cognitive performance using an international community sample. Cognitive tasks assessed working memory [executive functioning (EF) theory], mental state attribution [theory of mind (ToM)], and global/local visual processing [weak central coherence (WCC) theory]. Structural equation modelling (SEM) demonstrated sleep disturbance and anxiety mediated the relationship of autism traits on measures of EF, but not WCC and ToM. This suggests that treating the symptoms of sleep disturbance and anxiety may lead to improvements in working memory.
The effect of the strain rate on the longitudinal modulus of cellulosic fibres
Authors: Zizek Marko , Czibula Caterina , Hirn Ulrich 
Published: September 2022

AbstractThe longitudinal stiffness of cellulosic fibres plays an important role in the mechanical performance of many products these fibres are used for. Especially, the fibres’ viscoelastic properties are having an influence on the product performance.In this work, tensile testing at different strain rates was performed on single fibres to investigate the rate dependence of their moduli. Four different fibre types were tested: chemi-thermomechanical softwood pulp (CTMP), bleached chemical softwood pulp (CP), unbleached softwood kraft pulp (UKP), and viscose (VIS). For each fibre sample, ten strain rates ranging from 0.113% s−1 to 800% s−1 were applied. The rate-dependent modulus $$E_{r}$$

E
r

of each fibre at each strain rate was calculated by linearly fitting the stress–strain curves. By obtaining the values of the normalized modulus, a slope value per decade was calculated to quantify the rate dependence. To exclude possible plastic and relaxation effects, two additional experiments were used: a force-controlled loading–unloading experiment and a reverse rate protocol.All cellulosic fibres tested exhibited rate-dependent behaviour with a log-linear relationship between loading rate and modulus. For each tenfold increase in loading rate we found an increase in modulus up to nearly 20%—depending on the fibre type. Viscose fibres exhibit the highest rate dependence, whereas chemical softwood pulp fibres exhibit the lowest.
Kritische politische Theorie der Präfiguration
Authors: Sörensen Paul 
Published: September 2022

ZusammenfassungAuf der Grundlage eines idealtypisierenden Sortierungsversuchs politischen Theoretisierens soll eine zumindest rudimentäre Programmatik für eine auch utopistische kritische politische Theorie skizziert werden. Um deren spezifisches Erkenntnisinteresse und ihre Verfahrensweisen herauszuarbeiten, wird auf das zuletzt im Kontext sozialer Bewegungen revitalisierte Konzept der Präfiguration zurückgegriffen. Ein das Präfigurative in dreifacher Weise integrierendes Unterfangen vermag im besten Fall einen Schritt über die oft negativistischen Formen kritischen Theoretisierens hinaus zu tun, ohne dadurch in rein ideal-theoretische Bahnen zu geraten. Um diese Programmatik zu umreißen, begibt sich die Abhandlung sowohl auf Spurensuche bei Vertretern der sogenannten „ersten Generation“ der Kritischen Theorie, um zugleich aber auch aus anderen Kontexten, wie etwa der Utopie- und Bewegungsforschung, zu schöpfen.

Published: September 2022

AbstractClustering mixed-type data, that is, observation by variable data that consist of both continuous and categorical variables poses novel challenges. Foremost among these challenges is the choice of the most appropriate clustering method for the data. This paper presents a benchmarking study comparing eight distance-based partitioning methods for mixed-type data in terms of cluster recovery performance. A series of simulations carried out by a full factorial design are presented that examined the effect of a variety of factors on cluster recovery. The amount of cluster overlap, the percentage of categorical variables in the data set, the number of clusters and the number of observations had the largest effects on cluster recovery and in most of the tested scenarios. KAMILA, K-Prototypes and sequential Factor Analysis and K-Means clustering typically performed better than other methods. The study can be a useful reference for practitioners in the choice of the most appropriate method.
Advocating a Valid Cultural Alltagspsychologie
Authors: von Fircks Enno 
Published: September 2022

AbstractIn the present article, I criticize the narrow-minded definitions of validity as done by mainstream psychology and its quantitative imperative. I argue that validity should be defined in a broader way such as enhancing the transparency of a present scientific inquiry. The consequence of a too narrow-minded focus upon validity is that specific psychological phenomena are bracketed, and its analysis is argued as non-valid or non-scientific. Psychological phenomena such as watching television, going to sleep, and talking to friends—among many others—are part and parcel of human everyday life. For such phenomena, we are not able to control variables or a specific setting. Yet, I argue that this is not necessary as we can unravel those psychological mechanisms within a different scientific lens that I call a cultural Alltagspsychologie (folk psychology) in tradition of Jerome Bruner. This Alltagspsychologie analyzes a person’s individual social relatedness in time that is argued to demonstrate his/her personal culture and accounts for his/her relations with his environment as well as with himself/herself. Analyzing this relatedness is possible by the TEM diagrams that can decipher the development of culture from past to future and show equally potential alterations of exactly that culture. In the end, I argue that such a scientific approach can be also called valid.
ONp-ADIC INTERPOLATION IN TWO OF MAHLER’S PROBLEMS
Authors: DE PAULA MIRANDA BRUNO , LELIS JEAN 
Published: September 2022

AbstractMotivated by thep-adic approach in two of Mahler’s problems, we obtain some results onp-adic analytic interpolation of sequences of integers$(u_n)_{n\geq 0}$. We show that if$(u_n)_{n\geq 0}$is a sequence of integers with$u_n = O(n)$which can bep-adically interpolated by an analytic function$f:\mathbb {Z}_p\rightarrow \mathbb {Q}_p$, then$f(x)$is a polynomial function of degree at most one. The case$u_n=O(n^d)$with$d>1$is also considered with additional conditions. Moreover, ifXandYare subsets of$\mathbb {Z}$dense in$\mathbb {Z}_p$, we prove that there are uncountably manyp-adic analytic injective functions$f:\mathbb {Z}_p\to \mathbb {Q}_p$, with rational coefficients, such that$f(X)=Y$.

AbstractIn Gale crater on Mars, the rover Curiosity has discovered evidence of fluid mobilization of the redox‐sensitive element manganese. We present results for Mn from Curiosity's Alpha Particle X‐ray Spectrometer (APXS), which show that the average MnO concentration in mudstone‐dominated sedimentary units (0.22 wt%) is about one‐half of the concentration in the average Mars crust (0.44 wt%). Geochemical trends indicate that Mn in the sedimentary bedrock, most of which has a basaltic provenance, was leached by chemical alteration and dissolution. In >350 vertical meters of mudstone‐dominated strata, the apparent leaching of Mn and retention of Fe in Fe‐O‐H phase(s) resulted in the fractionation of Fe and Mn, indicating relatively moderate Eh‐pH fluid conditions that were not highly alkaline, reducing, or oxidizing. Exceptions are fracture‐associated, silica‐rich haloes where both Mn and Fe were leached by low pH fluids. The rover also discovered Mn‐rich veins, nodules, and patchy, dark coatings on rock surfaces, which are variably associated with enrichments in Fe, P, Cl, and/or Zn. These Mn‐rich features represent ∼1% of the 1029 APXS measurements acquired over ∼25 km of rover traverse. A thermochemical model shows that dissolved Mn2+ could have been concentrated via evaporation, sublimation, and/or freezing. Manganese was then likely precipitated in localized features when >99.99% of the Mn2+‐bearing water was removed from the system. These findings indicate that Mn was mobile in Gale crater and therefore bioavailable as a potential energy source for life.
Forecasting GIC Activity Associated With Solar Wind Shocks for the Australian Region Power Network

Published: September 2022

AbstractsSpace weather induced Geomagnetically Induced Currents (GICs) that are hazardous to power networks at high latitudes are often the result of rapid changes in near‐Earth space current systems such as the auroral electrojets and field‐aligned currents. GIC activity at low‐middle latitudes may be driven by currents that are more relevant to these regions such as the ring or magnetopause current systems. Solar wind shocks create rapid changes in the magnetopause current that manifest as large step changes in the geomagnetic field at the Earth's surface, often referred to as geomagnetic sudden impulses (SIs), that are effective drivers of GIC activity in power networks at low‐middle latitudes. This paper describes the results of a study into the relationship between the driver of SIs, solar wind shocks, and their potential impact on power systems in the Australian region, as quantified by a GIC‐index. The initial data set for analysis was produced by programmatically scanning solar wind data obtained from the ACE satellite spanning the period 1998–2008 for solar wind shocks. For each identified solar wind shock, geomagnetic field data from the Australian region were analyzed to determine the corresponding SI and GIC‐index. Statistical analyses of GIC‐indices and various solar wind parameters associated with the shocks resulted in an empirical model that is a function of solar wind dynamic pressure, geomagnetic latitude, and change in solar wind speed with good operational predictive capability. This model was further assessed using online catalogs of solar wind shock events.

AbstractUnderstanding the role of coral reefs on air‐sea CO2 exchange is essential to accurately estimate carbon budgets throughout the tropical and subtropical oceans. Results from research conducted in humid marine environments show coral reefs are mainly net sources of CO2 to the atmosphere due to calcification being dominant over respiration and dissolution. However, coral reefs are also found bordering deserts in the subtropical high‐pressure belt. Here, we present results from concurrent direct measurements of air‐sea CO2 exchange over fringing coral reefs and open sea bordered by hyper‐arid deserts in the Gulf of Eilat (Aqaba). The fringing coral reefs were found to be a net sink of CO2 at −1.62 ± 4 μmol m−2 s−1 sequestering 1.96 times more CO2 than adjacent open sea. The CO2 fluxes showed a negative correlation with some local meteorological parameters such as humidity, wind speed, and net radiation but were positively correlated to air temperature. The air‐sea CO2 fluxes were also found to be correlated with dust, which is believed to trigger metabolic processes in bacteria and phytoplankton in the low‐nutrient, low‐chlorophyll sea of the study site. Results are compared to measurements from the humid marine setting of the Great Barrier Reef, Australia.
