AbstractIntracranial epidermoid cysts are benign slow-growing ectodermal inclusions that account for less than 1% of all intracranial tumors. We retrospectively reviewed 36 such cases to evaluate the demographic characteristics, clinical manifestations, anatomical distribution, surgical management, and treatment outcome of these tumors. Additionally, we sought to identify the relationship between median or paramedian cistern tumor localization and clinical parameters, such as recurrence risk, hospitalization duration, and postoperative complication rates. The most frequently observed neurological symptoms were transient headaches (77.8%), dizziness (36.1%), CN VII palsy (19.4%), CN VIII hearing difficulty (19.4%) and cerebellar signs (19.4%). The most common surgical approaches included retrosigmoid (36.1%), subfrontal (19.4%) and telovelar (19.4%) approaches; gross total resection was feasible in 83.3% of cases. The postoperative complication rate was 38.9%. Tumors were more frequently found in the paramedian cisterns (47.2%), followed by the median line cisterns (41.6%). Multivariate analysis revealed that postoperative hydrocephalus and age < 40 years were prognostic factors for tumor recurrence. Median-like tumor location was a risk factor for the presence of symptomatic hydrocephalus both preoperatively and postoperatively, increasing the likelihood of protracted hospitalization (> 10 days). Despite their benign histopathological nature, these tumors have an important clinical resonance, with a high rate of postoperative complications and a degree of recurrence amplified by younger age and hydrocephalus.

AbstractOne of modern analytical chemistry main challenges is providing as fast as possible results in different application fields. In this view, real-time analysis techniques are experiencing ever-increasing success as they can provide data quickly, almost without sample preparation steps. Most of real-time approaches are based on direct mass spectrometry (DMS), a method of analyzing samples without the need for separation or pre-treatment steps. Instead, the sample is directly introduced into the mass spectrometer for analysis. In this context, ambient ionization mass spectrometry (AIMS) techniques are widely represented and successfully used. Extractive-liquid sampling electron ionization-mass spectrometry (E-LEI-MS) represents a different analytical strategy that allows coupling ambient sampling with electron ionization (EI), avoiding any sample preparation step and providing identification based on the comparison with the National Institute of Standards and Technology (NIST) library spectra. E-LEI-MS consists of a dispositive for solvent release and sampling at ambient conditions coupled with an EI source of a single quadrupole mass spectrometer. A micromanipulator allows fine (x,y,z) positioning of a sampling tip. MS can operate in scan or SIM modes depending on the application goals and requirements. Several preliminary successful results were already obtained due to the highly informative EI mass spectra generation. The system was applied to the analysis of active ingredients in pharmaceutical tablets, pesticides on fruit peel, a drug of abuse (cocaine) determination in banknotes, and analysis of unknown components on painting surfaces. Both forensic and artwork applications allowed determining the spatial distribution of the analytes. Here we present a proof-of-concept of E-LEI-MS for targeted/non-targeted analysis and semi-quantitative detection.
Tidal modulation of the seismic activity related to the 2021 La Palma volcanic eruption

Published: April 2023

AbstractThe volcanic eruption at La Palma started on September 19, 2021. The eruption was preceded by a seismic swarm that began on September 11, although anomalous seismicity has been observed on the island since 2017. During the co-eruptive phase of the seismic activity, hypocenters depth was generally less than 15 km, save for the period between November 10 and November 27, when hypocenters ranged in the depth from 15 to 40 km. The eruption ended on December 13, 2021. We compute tidal stress for each earthquake at the hypocenter depth and find statistically significant correlations between the occurrence times of the earthquakes and the confining tidal stress values and stress rates. The correlation is depth-dependent, and ocean-loading tides have a stronger effect than body tides. We find that tidal stress variations contribute to the eruption onset and that certain explosive events, typical in Strombolian type volcanoes, seem to occur preferentially when the tidal stress rate is high. Our analysis supports the hypothesis that tides may modulate earthquake activity in volcanic areas, specifically during magma migration at shallow depths. A conceptual model is proposed, which could have a general application in the Canary Islands archipelago and other volcanic islands.

AbstractCompared to microbiomes on other skin sites, the bacterial microbiome of the human hand has been found to have greater variability across time. To increase understanding regarding the longitudinal transfer of the hand microbiome to objects in the built environment, and vice versa, 22 participants provided skin microbiome samples from their dominant hands, as well as from frequently and infrequently touched objects in their office environments. Additional longitudinal samples from home environments were obtained from a subset of 11 participants. We observed stability of the microbiomes of both the hand and built environments within the office and home settings; however, differences in the microbial communities were detected across the two built environments. Occupants’ frequency of touching an object correlated to that object having a higher relative abundance of human microbes, yet the percent of shared microbes was variable by participants. Finally, objects that were horizontal surfaces in the built environment had higher microbial diversity as compared to objects and the occupants’ hands. This study adds to the existing knowledge of microbiomes of the built environment, enables more detailed studies of indoor microbial transfer, and contributes to future models and building interventions to reduce negative outcomes and improve health and well-being.
Emotion regulation mediates the relationship between social frailty and stress, anxiety, and depression

Published: April 2023

AbstractSocial frailty refers to an inability to meet basic social needs and has been identified as a threat to physical and mental health. Although social frailty has been linked with many adverse health and well-being outcomes, potential mediators of the relationship between social frailty and well-being remain poorly understood. Emotion regulation refers to the capacity to alter the experience of emotions to behave in accordance with a desired goal. The present study was designed to provide the first direct test of whether emotion regulation mediates the relationships between social frailty and important well-being outcomes (stress, anxiety, and depression). A total of 790 participants completed validated measures of social frailty, stress, anxiety, depression, and emotion regulation. In line with our preregistered hypotheses, higher social frailty predicted increased stress, anxiety, and depression, and each of these relationships were partially mediated by emotion regulation capacity. These data provide novel evidence that emotion regulation abilities may serve as a protective factor against the negative consequences of social frailty.

AbstractWe investigated whether different doses of undenatured type II collagen (undenatured collagen, UC-II) help improve monosodium iodoacetate (MIA)-induced (osteoarthritis) OA in young and old rats. A total of 70 rats were divided into five groups: (1) control; (2) MIA (a single intra-articular injection of MIA); (3)–(5) MIA+ Undenatured Collagen with various oral doses (0.66, 1.33, and 2 mg/kg). The results showed that all doses of undenatured collagen in both age groups reduced knee diameter, while the two higher doses (1.33 mg/kg and 2 mg/kg) reduced the Mankin score and increased most gait measurements as early as day 14 compared to the MIA rats. However, the 2 mg/kg dose showed the best efficacy in improving Mankin score and gait measurements by 28 days post-OA induction. In young but not old rats, all doses of undenatured collagen reduced the Kellgren-Lawrence score compared to the MIA group. Undenatured collagen reduced the levels of most inflammatory and cartilage breakdown markers in serum and knee joint cartilage in both age groups. In conclusion, this data suggests that while all doses of undenatured collagen supplementation may ameliorate MIA-induced OA symptoms, the higher doses showed faster improvement in gait measurements and were more efficacious for overall joint health in rats.

AbstractPostoperative nausea and vomiting (PONV) can lead to various postoperative complications. The risk assessment model of PONV is helpful in guiding treatment and reducing the incidence of PONV, whereas the published models of PONV do not have a high accuracy rate. This study aimed to collect data from patients in Sichuan Provincial People’s Hospital to develop models for predicting PONV based on machine learning algorithms, and to evaluate the predictive performance of the models using the area under the receiver characteristic curve (AUC), accuracy, precision, recall rate, F1 value and area under the precision-recall curve (AUPRC). The AUC (0.947) of our best machine learning model was significantly higher than that of the past models. The best of these models was used for external validation on patients from Chengdu First People’s Hospital, and the AUC was 0.821. The contributions of variables were also interpreted using SHapley Additive ExPlanation (SHAP). A history of motion sickness and/or PONV, sex, weight, history of surgery, infusion volume, intraoperative urine volume, age, BMI, height, and PCA_3.0 were the top ten most important variables for the model. The machine learning models of PONV provided a good preoperative prediction of PONV for intravenous patient-controlled analgesia.

AbstractInvestigation of Homo sapiens’ palaeogeographic expansion into African mountain environments are changing the understanding of our species’ adaptions to various extreme Pleistocene climates and habitats. Here, we present a vegetation and precipitation record from the Ha Makotoko rockshelter in western Lesotho, which extends from ~60,000 to 1,000 years ago. Stable carbon isotope ratios from plant wax biomarkers indicate a constant C3-dominated ecosystem up to about 5,000 years ago, followed by C4 grassland expansion due to increasing Holocene temperatures. Hydrogen isotope ratios indicate a drier, yet stable, Pleistocene and Early Holocene compared to a relatively wet Late Holocene. Although relatively cool and dry, the Pleistocene was ecologically reliable due to generally uniform precipitation amounts, which incentivized persistent habitation because of dependable freshwater reserves that supported rich terrestrial foods and provided prime locations for catching fish.

AbstractMost of the shape classification methods are based on a single closed contour. However, practical shapes always have complex contours, for example, a combination of multiple open contours. How to accurately identify complex shapes is an unsolved problem. In this research, a novel method is proposed to classify complex shapes. The proposed method firstly encodes a complex shape to an angle code and a sparsity code, then input these codes to a 1‐D CNN for extracting features and classification. Experiments on two datasets show this novel method is superior in terms of classification accuracy. These two datasets are practical shape dataset collected by this paper on internet and MPEG‐7 CE‐1 Part B. The proposed method achieves higher classification accuracy than compared methods. In order to show the performance of the proposed method on each class, the accuracy on each class is analyzed. Ablation experiment is conducted to show the contribution of each module in the network. The result shows that each module is meaningful in the network, because without any module the accuracy drops.
An adaptive grid integrated photovoltaic system with perturb T–S fuzzy based sliding mode controller MPPT tracker: An experimental realization

Published: April 2023

AbstractThis research work proposes an adaptive grid integrated photovoltaic (PV) system with perturb adaptive T–S fuzzy approach‐based sliding mode controller (SMC) (T–S fuzzy SMC) as a maximum power point tracker (MPPT). In this work, a grid‐connected single‐phase H‐bridge microinverter is employed which is controlled using sine pulse width modulation (SPWM). The proposed variable step sliding mode controller‐based MPPT has high PV tracking efficiency, strong adaptive capability, high precision, simpler hardware implementation, better transient performance, and rapid convergence velocity compared to other recent MPPT algorithms under discontinuous non‐linear operating conditions. The Takagi–Sugeno (T–S) based perturb adaptive sliding mode controller MPPT generates adaptive perturbation and has high‐performance efficiency under changing solar irradiance levels compared to the Mamdani approach. The proposed inverter controller provides better power quality performance with less total harmonic distortion (THD) as the SPWM technique can minimize lower‐order harmonics. Experimental results justify the control system design with high performance and PV system MPPT efficiency is found 98.45% using proposed T–S fuzzy SMC method. From practical results THD of grid voltage/current is found according to IEEE 519 coder, which is less than the 5% limit.
Revisiting the cycle-rotation connection for late-type stars
Authors: Mittag M. , Schmitt J. H. M. M. , Schröder K.-P. 
Published: April 2023

Aims. We analyse the relation between the activity cycle length and the Rossby number, which serves as a ‘normalised’ rotation period and appears to be the natural parameter in any cycle relation.
Methods. We collected a sample of 44 main sequence stars with well-known activity cycle periods and rotation periods. To compute the Rossby numbers from the observed rotation periods, we used the respective B − V-dependent empirical turnover-times and derived the empirical relation between the cycle length and Rossby number.
Results. We found a linear behaviour in the double-logarithmic relation between the Rossby number and cycle period. The bifurcation into a long and a short period branch is clearly real but it depends, empirically, on the colour index B − V, indicating a physical dependence on effective temperature and position on the main sequence. Furthermore, there is also a correlation between cycle length and convective turnover time with the relative depth of the convection zone. Based on this, we derived empirical relations between cycle period and Rossby number individually for narrow B − V ranges, for both cycle branches, as well as a global relation for the short-period branch. For the short period cycle branch relations, we estimated a scatter of the relative deviation between 14% and 28% on the long-period cycle branch. With these relations derived purely from stellar data, we obtained a good match with the 10.3−1.0+1.1 yr period for the well known 11-year solar Schwabe cycle and a long-period branch value of 104−34+50 yr for the Gleissberg cycle of the Sun. Finally, we suggest that the cycles on the short-period branch appear to be generated in the deeper layers of the convective zone, while long-period branch cycles seem to be related to fewer deep layers in that zone.
Conclusions. We show that for a broader B − V range, the Rossby number is a more suitable parameter for universal relation with cycle-rotation than just the rotation period alone. As proof, we demonstrate that our empirical stellar relations are consistent with the 11-year solar Schwabe cycle, in contrast to earlier studies using just the rotation period in their relations. Previous studies have tried to explain the cycle position of the Sun in the cycle-rotation presentation via other kinds of dynamo, however, in our study, no evidence is found that would suggest another type of dynamo for the Sun and other stars.

Published: April 2023

AbstractPatients with systemic lupus erythematosus have a higher incidence of neoplasms associated with human papillomavirus infections, such as those that affect the vulva, the vagina, and the cervix; however, little is known about the frequency of anal cancer among these patients. Although there are recommendations for screening for this cancer in immunosuppressed individuals, it is possible that this procedure is not strictly followed. We describe the case of a 47-year-old woman with systemic lupus erythematosus who was treated with immunosuppressants and developed advanced anal squamous cell carcinoma after adequate treatment and healing of a high-grade cervical squamous intraepithelial lesion. Five years after the completion of the anal cancer treatment, the patient presented with cystic hepatic lesions that were histopathologically confirmed to be metastatic squamous cell carcinoma. This report aimed to highlight the need for anal cancer screening in patients with lupus, particularly if there was a history of cervical cytopathological alterations.
Colonoscopic Laxative Instillation for the Fecal-loaded Colon: A Case Series
Authors: Wagle Suhas D. , Wagle Aneeta S. 
Published: April 2023

Abstract
Context Postoperative, critically ill, and elderly patients often have fecal loading or impaction. In a few such patients, disimpaction of fecalomas and colon cleansing are difficult. Bowel obstruction, megacolon, lower gastrointestinal bleeding, and gut perforation are complications that may ensue. Oral laxatives or enemas may only be partially effective. Surgical intervention may be needed for salvage or to treat complications.
Series and Design Fourteen hospitalized cases with defecation disorder due to fecal loading of the colon were enrolled for retrospective analysis. Colonoscopic instillation of mannitol and/or lactulose was undertaken as an intervention when the use of oral laxatives was either ineffective or unfeasible, and enema had yielded poor results.
Results Ten patients had satisfactory outcomes for fecal clearance, whereas four patients with poor or incomplete responses underwent repeat interventions or surgery. No significant complications were encountered due to this therapy.
Conclusion Colonoscopic instillation of mannitol or lactulose in fecal-loaded critically ill patients results in a safe and satisfactory fecal clearance.
Teaching Hebrew as second language in Arab schools in Israel
Authors: Manor Rama , Binhas Adi 
Published: April 2023

Abstract
Students belonging to the substantial Palestinian-Arab minority in Israel – about one-fifth of the population –
are required to study Hebrew as a second language (SL). This study analyzes the policy of teaching Hebrew as SL through content
analysis of policy papers, questionnaires and interviews with teachers. It aims to elicit the meaning of studying the majority
language by the minority in practical and ethnonational identity terms. The findings indicate that the current policy aims at
promoting the acquisition of spoken Hebrew for the purpose of integration in higher education and the labor market, and that
international contents are more prominent as part of the growing openness in Palestinian society in Israel. In terms of identity,
the importance of Hebrew in that society has grown, but also posed challenges in terms of the minority’s sense of belonging to
Israel and identification with the values attendant on acquiring the language. Overall, we identified interfaces between three
identity spheres: the Palestinian ethnonational identity, the Jewish-Israeli identity as encountered through Hebrew language
studies, and the global identity as represented by educational and employment opportunities and values.
