Predicting buoyant jet characteristics: a machine learning approach
Authors: Hassanzadeh Hossein , Joshi Saptarshi , Taghavi Seyed Mohammad 
Published: June 2023

Abstract
We study positively buoyant miscible jets through high-speed imaging and planar laser-induced fluorescence methods, and we rely on supervised machine learning techniques to predict jet characteristics. These include, in particular, predictions to the laminar length and spread angle, over a wide range of Reynolds and Archimedes numbers. To make these predictions, we use linear regression, support vector regression, random forests, K-nearest neighbour, and artificial neural network algorithms. We evaluate the performance of the aforementioned models using various standard metrics, finding that the random forest algorithm is the best for predicting our jet characteristics. We also discover that this algorithm outperforms a recent empirical correlation, resulting in a significant increase in accuracy, especially for predicting the laminar length.
Mycobacterial type VII secretion systems
Authors: Famelis Nikolaos , Geibel Sebastian , van Tol Daan 
Published: June 2023

Abstract
Mycobacteria, such as the pathogen M. tuberculosis, utilize up to five paralogous type VII secretion systems to transport proteins across their cell envelope. Since these proteins associate in pairs that depend on each other for transport to a different extent, the secretion pathway to the bacterial surface remained challenging to address. Structural characterization of the inner-membrane embedded secretion machineries along with recent advances on the substrates’ co-dependencies for transport allow for the first time more detailed and testable models for secretion.

Abstract

Objectives
Central precocious puberty (CPP) is one of the common reasons for referral to pediatric endocrinology. Magnetic resonance imaging (MRI) is used to rule out intracranial pathologies. However, there is insufficient information in the literature about bone marrow abnormalities on MRI in CPP cases. The aim of this study was to evaluate the apparent diffusion coefficient (ADC) values obtained from bone marrow diffusion weight images (DWI) of cranial bone structures and the status of sphenooccipital synchondrosis (SOS) in CPP.

Methods
MRI data from 6-to 9-year-old girls with CPP and a healthy control group were evaluated. Anthropometric data, FSH, LH, and oestradiol tests were recorded, and the relationship between SOS status, DWI-ADC values of the clivus, parietal bone, and occipital protuberance were compared.

Results
The study included 146 girls, 79 CPP, and 67 healthy aged 6–9 years (median: 8 (2)). The diagnosis age was 8.30 ± 0.8 years. The ADC values were significantly lower on CPP than normal controls (p=<0.05). In the CPP group, pattern 1 was found at 2 % (n=2), pattern 2 at 3.5 % (n=3), and pattern 3 at 3.5 % (n=3) in clivus sphenooccipital synchondrosis. There was no correlation between the mean parietal, occipital, and clivus ADC values and any variable (p>0.05).

Conclusions
DWI-MRI ADC analysis can be used as a quantitative radiological marker for early detection of CPP, even before changes in sphenooccipital synchondrosis.

Published: June 2023

Abstract
This paper presents a remote method used for engaging teenagers as citizen sociolinguists within the research project Teen Speak in Estonia. The project, launched in January 2020, aims to investigate young people’s language by creating the first systematic dual corpus of Estonian teenagers’ spoken language and text messaging. Previously, youth language in Estonia has not been the subject of much research. Yet scholarly attention to teenage language usage has been on the rise internationally, with corpora compiled in English and several other languages. The article describes the process of recruiting and training participants, as well as adjustments made to data collection in connection with the outbreak of COVID-19 and the restrictions which followed. While the pandemic did modestly interfere with the participatory approach, the data collection was successfully carried out, thanks primarily to well-networked and dedicated 9- to 18-year-old participants. Notwithstanding a gender imbalance, the corpus of 97 h of speech and nearly 60,000 words of text messages will facilitate research into Estonian teenagers’ Estonian–English codeswitching and other linguistic features, across two registers. The remote method is recommended for use elsewhere, especially in places where mutual trust prevails, and teenagers claim a fair amount of independence, responsibility and facility with online applications.
An economic evaluation of fine-needle cytology as the primary diagnostic tool in the diagnosis of lymphadenopathy

Published: June 2023

Abstract
Fine-needle aspiration cytology (FNAC) is commonly used to obtain a pre-surgical pathological diagnosis in many organs, but its cost-effectiveness in lymphadenopathy has not been studied yet. We calculated the cost and diagnostic accuracy of a diagnostic algorithm that uses FNAC as a first-line procedure and compared it to a purely surgical approach in 545 consecutive lymphadenopathies. In 74% of the cases, FNAC alone can obtain a sufficiently detailed diagnosis, avoiding the surgical biopsy. In doing so, the average cost of diagnosis is cut to less than one-third, the patient avoids an invasive procedure and the diagnosis is reached earlier. In conclusion, the systematic use of lymph node-FNAC in the initial assessment of lymphadenopathy is clinically and economically advantageous as it avoids surgical biopsies in cases where cytology can suffice.
Auf den Spuren des hellenistischen Judentums in Caesarea: Ein Jüdischer Psalmenforscher in Origenes’ Glosse im Kontext Rabbinischer Literatur
Authors: Niehoff Maren R. 
Published: June 2023

Abstract
This article offers a close reading of a gloss in Codex Ambrosianus B 106 of Origenes’ Hexapla on Psalms, which has in the past only been analyzed for its reference to the Patriarch. This article focuses on the Jewish scholar described in the gloss and analyzes his method of identifying Moses as the author of ten anonymous Psalms in view of Alexandrian scholarship. As Origen could only have communicated with his Jewish contemporary in Greek, the gloss provides unique insights into Hellenistic Judaism in 3d century Caesarea, which turns out to be well connected to Alexandrian methods of scholarship, available in late Antiquity in numerous intellectual centers of the Eastern Mediterranean, including Caesarea and Gadara. Moreover, the article points to conduits of communication between the Jewish Hellenistic scholar and rabbinic literature, where his conclusions resurface.
Plato’s
Phaedrus
and
Symposium
in the
Pseudo-Clementine Homilies
Authors: De Vos Benjamin M. J. 
Published: June 2023

Abstract
The presence of Plato and Platonic philosophy in the late antique Christian novel, the Pseudo-Clementine Homilies, has been underexamined. The present article takes a twofold approach: first, it discusses Platonic references and allusions in the disputes between Appion the grammarian and Clement, a follower of the apostle Peter (Homiliae Clementinae 4–6), and links them to the rest of the Homilistic narrative. Plato’s dialogues of the Symposium and, in particular, the Phaedrus turn out to be insightful philosophical and literary frameworks by means of which the Homilist reflects on the value of eros, paideia, rhetoric and philosophy, the value of written discourse, and truth. Secondly, this article also compares the Pseudo-Clementine Homilies with (other) novels and narratives from the Second Sophistic that intertextually engage with similar Platonic motifs and passages. My analysis reveals how the Homilist, as a Christian novelist with strong philosophical (and one might say Sophistic) interests, is a remarkable member of the late antique, cultural dialogue, in which the reception of Plato’s dialogues took place.

OBJECTIVES
Diagnostic errors, termed “missed opportunities for improving diagnosis” (MOIDs), are known sources of harm in children but have not been well characterized in pediatric hospital medicine. Our objectives were to systematically identify and describe MOIDs among general pediatric patients who experienced hospital readmission, outline improvement opportunities, and explore factors associated with increased risk of MOID.

PATIENTS AND METHODS
Our retrospective cohort study included unplanned readmissions within 15 days of discharge from a freestanding children’s hospital (October 2018–September 2020). Health records from index admissions and readmissions were independently reviewed and discussed by practicing inpatient physicians to identify MOIDs using an established instrument, SaferDx. MOIDs were evaluated using a diagnostic-specific tool to identify improvement opportunities within the diagnostic process.

RESULTS
MOIDs were identified in 22 (6.3%) of 348 readmissions. Opportunities for improvement included: delay in considering the correct diagnosis (n = 11, 50%) and failure to order needed test(s) (n = 10, 45%). Patients with MOIDs were older (median age: 3.8 [interquartile range 1.5–11.2] vs 1.0 [0.3–4.9] years) than patients without MOIDs but similar in sex, primary language, race, ethnicity, and insurance type. We did not identify conditions associated with higher risk of MOID. Lower respiratory tract infections accounted for 26% of admission diagnoses but only 1 (4.5%) case of MOID.

CONCLUSIONS
Standardized review of pediatric readmissions identified MOIDs and opportunities for improvement within the diagnostic process, particularly in clinician decision-making. We identified conditions with low incidence of MOID. Further work is needed to better understand pediatric populations at highest risk for MOID.
Evaluación de sistemas constructivos para vivienda de interés social utilizando la Matriz QFD

Costa Rica tiene un déficit habitacional para su población más vulnerable. Se identifica una carencia de información y evaluación de posibles sistemas constructivos para vivienda de interés social que permita mejores resultados en factores como alcance, costo, calidad y tiempo de obra en las fases tempranas de un proyecto.
Se realizó una evaluación con un criterio técnico e imparcial para nueve (9) sistemas constructivos para viviendas de interés social unifamiliares, específicamente para las actividades de construcción de cimentaciones, muros y acabados, aplicando la herramienta de Matriz de Despliegue de Función de la Calidad (QFD).
La Matriz QFD traslada los requerimientos del usuario a los de producción utilizando “Que´s” y “Como´s” [6]. Las calificaciones finales se basan en una cantidad de ochocientos diez (810) resultados en función de las variables para dos actores de estudio (actor constructor y actor usuario). Respecto al actor constructor el sistema de concreto con columnas y baldosas horizontales, con un puntaje de 236,5, fue el sistema de mejor calificación.
Para el actor usuario el mejor sistema fue el de mampostería integral con un puntaje total de 196,3. Las cuantificaciones realizadas para cada sistema constructivo no son absolutas, dependen de factores como el mercado, normativas, percepción social, entre otras.
Si un sistema obtiene mejor calificación quiere decir que, para las variables consideradas, para su importancia asignada y para el usuario evaluado, ese sería el mejor sistema constructivo, no se debe interpretar que en términos absolutos un sistema con una mayor calificación es superior a los demás.
Spatial numerical model of decks for façade scaffolding
Authors: Ornstová Pavla , Dolejš Jakub , Kruis Jaroslav 
Published: June 2023

AbstractThis paper deals with the issue of spatial modeling of façade frame scaffolding, with the focus on developing a methodology for modeling subfloor components. A laboratory experiment on a standard scaffold base assembly consisting of two spans is described. Load tests were carried out, and additional measuring points were added to the measuring apparatus compared to the standard procedure. The nonlinear stiffness of the numerical models was derived from the measured value. Furthermore, planar models of the scaffold subfloors were created and validated against experiments. Finally, the paper proposes scaffold stiffness in the horizontal direction (perpendicular to the façade and parallel to the façade) that can be used in a full spatial member of the scaffold model.

Published: June 2023

AbstractThis study evaluates future changes in M-day minimum and maximum discharges in selected river basins of Slovakia, which have been divided into four groups, i.e., western, central, northern, and eastern Slovakia. Four types of data were available for the analysis, i.e., observed mean daily discharges, modeled mean daily discharges using the rainfall-runoff model, and simulated mean daily discharges according to the climate scenarios. The Indicators of Hydrological Alteration program was used to estimate the M-day discharges.The results revealed an increase in the M-day minimum discharges in northern Slovakia. Eastern and Western Slovakia show a decrease in M-day minimum discharges and an increase in m-daily maximum discharges by 2100.
The role of driver's eye height in the design of crest curves of roads
Authors: Khaska Khalil , Miletics Dániel 
Published: June 2023

AbstractThe driver's eye height from the ground, as what drivers can see on the road, is essential for their safety and for avoiding road hazards. Using the statistical analysis of vehicles sample, the statistical parameters of the measured set of values were determined. A one-sample t-test was done to check whether the measured sample differs from the driver's eye height value specified in the Hungarian design guidelines. A new range of driver's eye height has been found, which is considered an update to the current value and might be applied in the upcoming road design. Parallel with the eye-height analysis, sight distances at vertical crest curves were modeled by AutoCAD Civil 3D. The minimum radiuses of the crest curves were defined for human eye height and for sensors of autonomous vehicles.

Abstract
On 5 September 2022, an Mw 6.6 strike-slip earthquake occurred in Luding, Sichuan, China. It illuminates the seismic gap on the southern end of Xianshuihe fault zone, that is Moxi segment, and is the most damaging earthquake in Chinese Mainland since 2014. In this article, we use multiple seismological methods to analyze the basic characteristics of the Luding earthquake, including its source parameters, rupture process, aftershock distribution, and further discuss its implications on preseismic fault behavior and impact on short-term seismic hazard. Using near-field stations, we first revisit the source parameters of the mainshock and obtain a much shallower hypocentral depth (∼9.3 km) than previously reported. Next, we jointly inverse the teleseismic P-wave data and near-field strong-motion data to constrain the mainshock rupture process. The coseismic slip consists of two subevents that spans for ∼20 km and shows an overall unilateral rupture to the south-southeast direction. The earthquake has 90% of the seismic moment released in its first 10 s. Third, we relocate the first 34 days of aftershocks with both manual phase picks and cross correlation, and finally obtain 5269 well-located events. The aftershocks reveal a near-vertical Xianshuihe fault and two sets of unmapped faults off the major Xianshuihe fault: one set of strike-slip faults on the north-northwest of rupture and the other one on the west of mainshock that generates the most intense seismicity with prevalent normal faulting. By examining the aftershock evolution and Coulomb stress change, we find that postseismic processes evolve both on and off the major fault, and the western off-fault system has highly variable fault orientations. Finally, we calculate the Coulomb stress change by the Luding earthquake on surrounding faults. Results show that the north Anninghe fault is significantly loaded by the Luding earthquake (&gt;0.1 MPa), which poses high seismic hazard in the short term.
