Published: September 2023

AbstractWhen the Linear Parallel Bond Model (PBM) in Particle Flow Code is used to simulate intact rocks, a basic problem is how to determine the microscopic parameters that control the macroscopic properties of the modeled rocks. After simplifying the microscopic parameters of the PBM model, this study proposes a new method of inverse performance of the regression equations of the macroscopic parameters by the gray absolute correlation combined with regression analysis, which solves the drawbacks of the current manual trial parameter calibration method to a certain extent. When this method is applied to the calibration of the microscopic parameters of the siltstone, the numerical simulation results produce good agreement between the results derived from the finite element software (ABAQUS) both in terms of macroscopic parameters and damage forms.

Context. Pre-stellar cores represent a critical evolutionary phase in low-mass star formation. Characterisations of the physical conditions of pre-stellar cores provide important constraints on star and planet formation theory and are pre-requisites for establishing the dynamical evolution and the related chemical processes.
Aims. We aim to unveil the detailed thermal structure and density distribution of three early-stage cores -starless core L1517B and pre-stellar cores L694-2 and L429- with the high angular resolution observations of the NH3 (1,1) and (2,2) inversion transitions obtained with VLA and GBT. In addition, we explored if and where NH3 depletes in the central regions of the cores.
Methods. We calculated the physical parameter maps of gas kinetic temperature, NH3 column density, line width, and centroid velocity of the three cores utilising the NH3 (1,1) and (2,2) lines. We applied the mid-infrared extinction method to the Spitzer 8 μm map to obtain a high angular resolution hydrogen column density map. We examined the correlation between the derived parameters and the properties of individual cores. We derived the gas density profile from the column density maps and assessed the variation of NH3 abundance as a function of gas volume density.
Results. The measured temperature profiles of the cores L429 and L1517B show a minor decrease towards the core centre, dropping from ~9 K to below 8 K, and ~11 K to 10 K, while L694-2 has a rather uniform temperature distribution of ~9 K. Among the three cores, L429 has the highest central gas density, close to sonic velocity line width, and the largest localised velocity gradient, all indicative of an advanced evolutionary stage. We resolve that the abundance of NH3 becomes two times lower in the central region of L429, occurring around a (line-of-sight mass-averaged) gas density of 4.4 × 104 cm−3. Compared to Ophiuchus/H-MM1 which shows an even stronger drop of the NH3 abundance at 2 × 105 cm−3, the abundance variations of the three cores plus Ophiuchus/H-MM1 suggest a progressive NH3 depletion with increasing central density in pre-stellar cores.
Evolution of solar wind sources and coronal rotation driven by the cyclic variation of the Sun’s large-scale magnetic field
Authors: Finley A. J. , Brun A. S. 
Published: September 2023

Context. The strength and morphology of the Sun’s magnetic field evolve significantly during the solar cycle, with the overall polarity of the Sun’s magnetic field reversing during the maximum of solar activity. Long-term changes are also observed in sunspot and geomagnetic records; however, systematic magnetic field observations are limited to the last four cycles.
Aims. Here, we investigate the long-term evolution of the Sun’s magnetic field, and the influence this has on the topology and rotation of the solar corona.
Methods. The Sun’s photospheric magnetic field was decomposed into spherical harmonics using synoptic Carrington magnetograms from (1) the Wilcox Solar Observatory, (2) the Michelson Doppler Imager on board the Solar and Heliospheric Observatory, and (3) the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory. The time evolution of the spherical harmonic coefficients was used to explore the variation of the Sun’s magnetic field, with a focus on the large-scale modes. Potential field source surface extrapolations of the photospheric field were computed to follow topological changes in the corona.
Results. The sources of the Sun’s open magnetic field vary between the polar coronal holes and activity-driven features such as active regions, and equatorial coronal holes. Consequently, the mean rotation rate of the solar wind is modulated during each cycle by the latitudinal variation of open field footpoints, with slower rotation during minima and faster (Carrington-like) rotation during maxima.
Conclusions. Coronal rotation is sensitive to cycle to cycle differences in the polar field strengths and hemispherical flux emergence rates. The mean rotation of the corona varies similarly to the ratio of quadrupole to dipole energy. Cycle 23 maintained a larger fraction of quadrupolar energy in the declining phase, which kept the sources of the open magnetic flux closer to the equator, extending the period of faster equator-ward connectivity. The ratio of quadrupole to dipole energy could be a useful proxy when examining the impact of differential rotation on the coronae of other Sun-like stars.

AbstractThe present study describes the time-loss injuries among female and male athletes
of the Spanish rink hockey league during the 2021/22 season.We performed a retrospective cohort study on time-loss injuries, whereby the
athlete is prevented from participating in a training session or game because of
the injury.A total of 463 athletes were included, with 326 (70.4%) senior male and
137 (29.6%) female. Two hundred and eighty-two time-loss injuries were
recorded, the most common form being muscle injuries (112 episodes,
39.7%), especially those affecting the hip adductor muscles (52
episodes, 46.4% of muscle injuries). Most injuries were classified as
mild (1–7 days of time-loss) and the median return-to-play was 9.5 days
(range 1–180).Injury patterns were compared according to gender, position and moment: the
results showed significant differences between senior males and females, between
field players and goalkeepers, as well as between training and game, in terms of
injury nature and type. The injury incidence proportion was significantly higher
for field players compared to goalkeepers), and senior males had a significantly
higher risk than senior females.The present study provides a starting point for studying and preventing injuries
in rink hockey athletes.

Published: September 2023

AbstractCervical cancer screening, which was introduced into the programme of medical care covered by statutory health insurance in Germany in 1971 and has since been constantly updated through
quality assurance measures, was fundamentally revised and developed in 2008 through the Cervical Cytology Quality Assurance Agreement pursuant to Section 135(2) of the German Social Code
Book V [SGB V]. Since 2015 it has been mandatory for cytology facilities to record annual statistics based on the Munich Nomenclature III. The aim of this article is to present the results
of the annual statistics for 2019, which was the last year before the introduction of the cervical cancer screening programme in accordance with the Federal Joint Committee’s guideline on
organised cancer screening programmes 1.The annual statistics of the laboratories, including histology analyses performed up until 30 June the following year, are reported to the Regional Associations of Statutory Health
Insurance Physicians. The laboratories receive benchmark reports from their Regional Associations of Statutory Health Insurance Physicians, and these statistics are transmitted anonymously
to the National Association of Statutory Health Insurance Physicians (KBV).In 2019, 17609082 smears from 15608413 women were examined in Germany. Of these smears, 97.49% were normal and 2.51% showed atypical or suspicious changes, consisting mostly of minor
squamous epithelial changes in groups II-p (0.81%) and IIID1 (0.735%).Histology specimens are available for “Dysplasia findings with higher probability of regression” in group IIID1 (4.89% of initial IIID1 cytology findings), group IIID2 (18.60%), “unclear
or doubtful findings” in group III-p to x (20.7%), and “immediate precursors to cervical carcinoma” in group IV (83.1%) and group V (77.19%).In the cytology findings for group IVa-p, which corresponds to CIN 3 target lesions, the cytology correlated with the histology finding in 80.48% of cases.Lesions found in 2019: 23463 CIN 3 lesions, 668 adenocarcinomas in situ, 3891 malignant tumours, including 2342 cervical carcinomas of which 1743 were squamous cell carcinomas and 599
were cervical adenocarcinomas (25.57%); 1549 endometrial carcinomas and other malignancies.The data demonstrate the good practicability of cervical cancer screening in 2019. Higher grade lesions were reliably clarified histologically.

Published: September 2023

AbstractThe purpose of this study was to reveal the correlation between anteromedial (AM) and posterolateral (PL) femoral tunnel lengths in anatomical double-bundle anterior cruciate ligament (ACL) reconstruction and body size and knee morphology. Thirty-four subjects undergoing anatomical double-bundle ACL reconstruction were included in this study. Preoperative body size (height, body weight, and body mass index) was measured. Using preoperative magnetic resonance imaging (MRI), quadriceps tendon thickness and the whole anterior–posterior length of the knee were measured. Using postoperative computed tomography (CT), axial and sagittal views of the femoral condyle were evaluated. The correlation between measured intraoperative AM and PL femoral tunnel lengths, and body size and knee morphology using preoperative MRI and postoperative CT parameters was statistically analyzed. Both AM and PL femoral tunnel lengths were significantly correlated with height, body weight, posterior condylar length, and Blumensaat's line length. These results suggest that the femoral ACL tunnel length created using a transportal technique can be estimated preoperatively by measuring the subject's body size and/or the knee morphology using MRI or CT. For clinical relevance, surgeons should be careful to create femoral tunnel of sufficient length when using a transportal technique, especially in knees of subjects with smaller body size and knee morphology. Level of evidence is III.

Published: September 2023

AbstractHydatid disease is a parasitic disease caused most commonly by the tapeworm Echinococcus granulosus. Treatment options can range from observation to radical excision of the cyst. The most common site is the liver, and the most common extra-hepatic location is the lung. We present a rare case of a 22-year-old male, who presented with complaints of right upper quadrant abdominal pain for a duration of 3 months, which on evaluation was associated with eosinophilia and radiological imaging revealed an extra-hepatic hydatid cyst arising from the lesser omentum. Pericystectomy was performed, and the postoperative course was grossly uneventful. The cut section of the cyst and the final histopathological study confirmed the diagnosis. There are very few case reports in the literature of isolated omental hydatidosis, and we present one such unique case.

Published: September 2023

AbstractPrimary central nervous system lymphoma (PCNSL) is a rare form of CNS tumor that can be managed with curative intent using high-dose chemotherapeutic drugs. High-dose methotrexate is an essential drug for the management of PCNSL. We present a case of a 26-year-old man with a known comorbidity of Crigler–Najjar syndrome type II and a baseline bilirubin of 13.5 mg/dL, presented with somnolence and ataxia. In view of hyperbilirubinemia, the optimal treatment for CNS lymphoma, the De Angelis protocol, was modified for this patient. The patient tolerated the chemotherapy well with manageable fluctuations in bilirubin levels, followed by consolidation with whole-brain radiotherapy. He remains asymptomatic 6 months after the onset of the symptoms with the disease in complete remission. We highlight here this unusual case of PCNSL where high-dose methotrexate was used with close observation of liver function in view of hyperbilirubinemia in a known case of Crigler–Najjar syndrome.

Published: September 2023

AbstractDouble hit lymphoma (DHL) and double-expressor lymphoma (DEL) are now considered as aggressive types of diffuse large B cell lymphoma. DHL is characterized by a dual rearrangement of MYC and B cell lymphoma 2 (BCL-2) and/or B cell lymphoma 6 (BCL-6) and DEL by overexpression of MYC and BCL-2. Both DHL and DEL have aggressive presentation and are more common in elderly population. We present a case of 1 ½ years old boy who presented with bilateral proptosis, and diagnosed as non-Hodgkin lymphoma with central nervous system involvement. Immunohistochemistry revealed high expression of MYC and BCL-2. Fluorescence in situ hybridization studies done to rule out DHL showed no translocation of C-MYC, Bcl-2, and Bcl-6 and hence were confirmed as double-expressor high-grade B cell lymphoma. Dual expression of C- MYC, Bcl-2, or Bcl-6 always needs further evaluation to rule out the more aggressive DHL subtypes.

Abstract
Background Edoxaban is a non-vitamin K dependent oral anticoagulant (NOAC) licensed for venous thromboembolism (VTE) treatment or stroke prevention in atrial fibrillation. Major surgical procedures are not uncommon in anticoagulated patients but data on perioperative edoxaban management are scarce.
Patients and Methods Using data from the prospective DRESDEN NOAC REGISTRY, we extracted data on major surgical procedures in edoxaban patients. Periinterventional edoxaban management patterns and rates of outcome events were evaluated until day 30 after procedure.
Results Between 2011 and 2021, 3,448 procedures were identified in edoxaban patients, including 287 (8.3%) major procedures. A scheduled interruption of edoxaban was observed in 284/287 major procedures (99%) with a total median edoxaban interruption time of 11.0 days (25–75th percentile: 5.0–18.0 days). Heparin bridging was documented in 183 procedures (46 prophylactic dosages, 111 intermediate and 26 therapeutic dosages). Overall, 7 (2.4%; 95% CI: 1.2–4.9%) major cardiovascular events (5 VTE, 2 arterial thromboembolic events) and 38 major bleedings (13.2%; 95% CI: 9.8–17.7%) were observed and 6 patients died (2.1%; 95% CI: 1.0–4.5%). Rates of major cardiovascular events with or without heparin bridging were comparable (4/137; 2.9%; 95% CI: 1.1–7.3% vs. 3/82; 3.7%; 95% CI: 1.3–10.2%). Major bleedings occurred numerically more frequent in patients receiving heparin bridging (23/137; 16.8%; 95% CI: 11.5–23.9%) versus procedures without heparin bridging (9/82; 11.0%; 95% CI: 5.9–19.6%).
Conclusion Within the limitations of our study design, real-world periprocedural edoxaban management seems effective and safe. Use of heparin bridging seems to have limited effects on reducing vascular events but may increase bleeding risk.

Published: September 2023

Abstract
Objectives Small bowel capsule endoscopy (SBCE) technology detects small bowel lesions. Many factors affect its sensitivity. SBCE is also costly, and patients might not be able to repeat the test when results are equivocal. Instead of repeating the test, reading the results by two endoscopists might provide a better or a cheaper option in the right settings. We studied the sensitivity of SBCE when read by two different physicians and checked if, rather than repeating the examination, rereading the results improved its sensitivity. Furthermore, we studied the effect of small bowel transit time (SBTT) on the diagnostic yield.
Materials and Methods A retrospective cohort study on capsule endoscopies was conducted between 2018 and 2019 in a tertiary care center in Lebanon. A total of 42 patients with anemia or obscure gastrointestinal bleed were included for SBCE after a negative evaluation with upper and lower gastrointestinal (GI) endoscopy. Two specialists read the results. The second physician was blinded from the first reader's results. We compared the sensitivity of the two readings. SBTT correlation with the diagnostic yield was calculated.
Results Out of 42 patients, 18 tested positive in the first reading and 31 in the second reading. The diagnostic yield increased from 43 to 74% (p = 0.0043). Among the 33 patients who had a documented SBTT, longer SBTT correlated with a higher diagnostic yield (odds ratio [OR] > 1), but no statistical significance was demonstrated.
Conclusion Within the limitations of this study, we found that rereading capsule endoscopy can be more cost-effective than repeating the test.
Intermediate perfects

Abstract
The cross-linguistic variation in distribution and meaning of perfect constructions building on

have
+ past participle in Western European languages has been analysed in terms of the
aoristic drift, the shift from resultative via perfect to perfective past meaning that takes us from
‘classical’ perfect languages like English to ‘liberal’ perfect languages like French. This paper challenges the
(often implicit) assumption that there is a single path along the aoristic drift, resulting in a linear perfect scale.
Data coming from translation corpora reveal that the perfect in three ‘intermediate’ languages (Dutch, Catalan and
Breton) is sensitive to lexical aspect (state vs. event), narrativity and hodiernal vs. pre-hodiernal past time reference. These
meaning ingredients appear in different combinations in the three languages, thereby establishing them as independent dimensions
of variation. The conclusion that there are multiple paths along the aoristic drift has implications for the cross-linguistic
semantics of tense and aspect.
Exploring incongruity and humour in Linguistic Landscapes in Ghana
Authors: Akoto Osei Yaw , Onumah Ebenezer , Amoakohene Benjamin 
Published: September 2023

Abstract
In recent times, Linguistic Landscape (LL) research has been extended to cover several variables, domains, modes,
and geo-political contexts. Arguably, humour remains understudied in LL research. This article, therefore, examines incongruities
in LLs using a corpus of digital signs and incongruous inscriptions gathered across several mediums in urban Ghana. Drawing on
the incongruity theory, we examined the levels of incongruities in the corpus. The study found that incongruities in public signs
in urban Ghana manifest at the lexical, grammatical, semantic, and phonological levels. We conclude that the resolutions of these
incongruities induce laughter and humour in the audience with the shared sociolinguistic knowledge, and humour intelligence. The
findings have implications for the theory on humour and the research on LL.
Hindering breakdown in a long discharge tube by visible spectrum light illumination

Published: September 2023

Abstract
The effect of irradiation with visible spectrum light on breakdown in discharge tubes 75–80 cm long and 1.5 cm in inner diameter in rare gases at a pressure of ∼1 Torr was studied. A ramp voltage of variable slope in the range of ∼10–1–105 kV s−1 was applied to the tube anode. The tube was illuminated by radiation from fluorescent lamps operating in a continuous mode, as well as by LEDs or a laser diode operating in a pulsed mode. The breakdown voltage and the pre-breakdown ionization wave (IW) velocity were measured. Illumination led to a change in the breakdown potential. The sign of this change depended on the anode voltage rise rate dU/dt. At dU/dt > 102–103 kV s−1, the breakdown voltage decreased. A similar effect was observed earlier and was explained by the appearance of electrons in the discharge gap under the light action, as a result of which the breakdown delay time decreased. This, in turn, caused a decrease in the breakdown voltage. At dU/dt < 101–102 kV s−1, on the contrary, the breakdown potential increased; at dU/dt ∼ 0.1 kV s−1, this increase could reach 5–6 times. The dependence of the observed effect on the radiation intensity, its wavelength, and the illuminated area position on the tube surface is studied. The pre-breakdown IW behaved in an unusual way under these conditions: its velocity and the signal amplitude recorded by the capacitive probe increased when moving from the high-voltage anode to the cathode. It is assumed that the observed features are caused by the desorption of weakly bound electrons from the tube wall surface under the action of irradiation. These electrons create a current that charges the wall near the anode. Since the first stage of discharge ignition is the initial breakdown between the anode and the tube wall, the anode potential for such a breakdown should increase, which means an increase in the breakdown voltage. Additional experiments with the initiation of a preliminary IW by a pulse applied to the cathode, confirmed the existence of a charge on the wall near the anode.
