ABSTRACT

Objectives: Reporting our initial experience of 48 cases in application of vacuum-assisted ureteral access sheath in the retrograde intrarenal surgery.

Methods: Forty - eight patients who underwent retrograde intrarenal surgery at Department of Urology, Hue Central Hospital between May 2023 and May 2024 were evaluated retrospectively. The vacuum - assisted ureteral access sheath was applied in the procedure. Demographics, laboratory tests, peri - and postoperative and one-month follow- up results were analysed.

Results: The mean stones size was 14.3 ± 4.9 mm. 77.1% of cases had stones located in the lower calyx. The mean operative time was 42.9 ± 17.1 minutes. The 1 - month post - operative stone - free rate was 89.6%. Two patients experienced post - operative fever. The average length of hospital stay was 3.06 ± 1.04 days. There was no unplanned readmission.

Conclusions: Retrograde intrarenal surgery with vacuum-assisted ureteral access sheath is a safe and effective procedure, which can achieve excellent stone clearance.
Background Contamination of the Project Hephaistos Dyson Spheres Candidates
Authors: Ren Tongtian , Garrett Michael A. , Siemion Andrew P. V.
Published: May 2024

Project Hephaistos recently identified seven M-dwarfs as possible Dyson Spheres (DS) candidates. We have cross-matched three of these candidates (A, B and G) with radio sources detected in various all-sky surveys. The radio sources are offset from the Gaia stellar positions by ∼4.9, ∼0.4 and ∼5.″0 for candidates A, B, and G respectively. We propose that Dust obscured galaxies (DOGs) lying close to the line-of-sight of these M-dwarf stars significantly contribute to the measured WISE mid-IR flux densities in the WISE W3 and W4 wave bands. These three stars have therefore been misidentified as DS candidates. We also note that with an areal sky density of 9 × 10−6 per square arcsecond, Hot DOGs can probably account for the contamination of all 7 DS candidates drawn from an original sample of 5 million stars.

Formulation, in vitro and in vivo evaluation of olanzapine nanoparticles dissolving microneedles for transdermal delivery
Authors: Al-Shaibani Abulfadhel J. Neamah , Ghareeb Mowafaq M.
Published: May 2024

Olanzapine (OLZ) is classified as a typical antipsychotic drug utilized for the treatment of schizophrenia. Its oral bioavailability is 60% due to its low solubility and pre-systemic metabolism. Hence, the present work aims to formulate and evaluate OLZ nanoparticles dissolving microneedles (MNs) for transdermal delivery to overcome the problems associated with drug administration orally. OLZ nanoparticles were prepared by the nanoprecipitation method. The optimized OLZ nanoparticle formula was utilized for the fabrication of dissolving MNs by loading OLZ nanodispersion into polydimethylsiloxane (PDMS) micromould cavities, followed by casting the polymeric solution of polyvinylpyrrolidone(PVP-K30) and polyvinyl alcohol (PVA) to form MN matrix. The results revealed that the optimized OLZ nanoparticle formula (NP-5) exhibited particle size 115.76±5.45 nm, entrapment efficiency 78.4±5.46, and zeta potential -19.01±1.6 mV. The results of MNs revealed that MN-4 exhibits a high drug content of 98.52%, and ex vivo permeation through rabbit skin exhibited that MN-4 permeates more effectively than a simple patch by approximately 5.16 fold. In vivo pharmacokinetics study revealed that the area under curve AUC 0-∞ of MN-4 was 6054.56±376 ng. h/ml as compared with AUC0-∞ of marketed OLZ tablet was 3975.77±373 ng. h/ml. It can be concluded that the dissolving MN-4 patch is considered a promising formula to overcome the problems associated with drug administration orally and could improve drug bioavailability, in addition to the ease of administering the medication to schizophrenic patients.

Solution formula for generalized two-phase Stokes equations and its applications to maximal regularity: Model problems
Authors: Kajiwara Naoto
Published: May 2024

In this paper, we give a solution formula for the two-phase Stokes equations with and without surface tension and gravity over the whole space with a flat interface. The solution formula has already been considered by Shibata and Shimizu. However, we have reconstructed the formula so that we are able to easily prove resolvent and maximal regularity estimates. The previous work required the assumption of additional conditions on normal components. Here, although we consider normal components, the assumption is weaker than before. The method is based on an $ H^\infty $-calculus which has already been applied for the Stokes problems with various boundary conditions in the half-space.
Les aditus du théâtre d’Orange
Authors: Moretti Jean-Charles , Badie Alain , Dubourg Sandrine , Papadopoulou Anna
Published: May 2024

Les aditus du théâtre d’Orange sont les mieux conservés des théâtres de Narbonnaise. Ils ont été l’objet de nouvelles observations et de nouveaux relevés dans le cadre du programme pluriannuel de restauration du monument, commencé en 2016 et prévu pour s’achever en 2024. Construits dans la première phase du monument, à la fin de l’époque augustéenne, ils sont rectilignes, symétriques et alignés l’un sur l’autre en bordure du diamètre est-ouest de la cavea. Chacun d’eux était constitué d’un large passage dallé traversant la cavea et rejoignant l’orchestra. La partie qui passe sous la cavea était couverte de cinq voûtes. Elle était ouverte sur les basiliques du bâtiment de scène, la galerie périphérique de la cavea et sur un couloir coudé conduisant à un vomitoire donnant dans le premier maenianum. La partie à l’air libre permettait d’accéder au pulpitum, à la circulation dallée aménagée au pied de la cavea, entre le balteus et le repose-pied du premier gradin et, une fois passé le balteus, aux degrés bas bordant l’orchestra et à l’orchestra elle-même. Ces aditus, dont le plan reprenait celui du théâtre d’Arles, étaient principalement destinés aux spectateurs qui trouvaient place en bordure de l’orchestra et dans la moitié inférieure du premier maenianum. Ces spectateurs étaient aussi les principaux usagers des basiliques et ceux pour lesquels le rideau pouvait cacher de manière efficace les artistes et les décors placés sur le pulpitum avant le début des spectacles.
Les aditus maximi du théâtre antique de Vaison-la-Romaine
Authors: Mignon Jean-Marc
Published: May 2024

Très détruit et très restauré, le théâtre antique de Vaison-la-Romaine demeure néanmoins un objet d’étude précieux, livrant d’importantes informations sur son architecture. Parmi les parties basses de l’édifice, souvent taillées dans le substrat rocheux, les aditus maximi sont relativement bien conservés, permettant d’en décrire la disposition, les dimensions, les accès, et d’en restituer les superstructures. Leur observation permet en outre, au sein du plan symétrique du théâtre, de distinguer l’aditus oriental, sommairement traité et destiné à un usage charretier fonctionnel, de l’aditus occidental, davantage soigné et réservé à un usage piétonnier. Le plan de la ville antique explique pour partie cette distinction, montrant une nette dissymétrie dans les accès au théâtre : l’un prestigieux, à l’ouest, empruntant une rue reliant l’édifice de spectacle au forum, l’autre plus ordinaire, à l’est, formé d’un simple chemin débouchant sur une route d’accès à l’agglomération antique.
Les accès privilégiés dans les théâtres de Gaule romaine : configurations et usages
Authors: Ferreira Filipe
Published: May 2024

Les nombreux théâtres de Gaule romaine présentent des formules architecturales variées. Les choix qui président à leur construction dépendent de divers facteurs, comme l’insertion topographique ou l’évolution des pratiques inhérentes à l’édifice. Ces variations s’observent principalement dans les formes prises par les composantes de l’espace théâtral. Ainsi, les accès monumentaux menant à l’orchestra en sont une illustration pertinente. Ils se déclinent en Gaule sous plusieurs aspects qui traduisent parfois le recours à des solutions employées dans les théâtres du pourtour méditerranéen. Cependant, dans la plupart des cas, leur disposition, de part et d’autre du complexe scénique, révèle une conception différente des modalités d’accès au monument. Quelles que soient les formes adoptées, elles mettent en évidence aussi bien l’évolution d’un type monumental que les pratiques sociales qui peuvent y être attachées en contexte provincial.

The mammalian Siglec receptor sialoadhesin (Siglec1, CD169) confers innate immunity against the encapsulated pathogen group B Streptococcus (GBS). Newborn lung macrophages have lower expression levels of sialoadhesin at birth compared with the postnatal period, increasing their susceptibility to GBS infection. In this study, we investigate the mechanisms regulating sialoadhesin expression in the newborn mouse lung. In both neonatal and adult mice, GBS lung infection reduced Siglec1 expression, potentially delaying acquisition of immunity in neonates. Suppression of Siglec1 expression required interactions between sialic acid on the GBS capsule and the inhibitory host receptor Siglec-E. The Siglec1 gene contains multiple STAT binding motifs, which could regulate expression of sialoadhesin downstream of innate immune signals. Although GBS infection reduced STAT1 expression in the lungs of wild-type newborn mice, we observed increased numbers of STAT1+ cells in Siglece−/− lungs. To test if innate immune activation could increase sialoadhesin at birth, we first demonstrated that treatment of neonatal lung macrophages ex vivo with inflammatory activators increased sialoadhesin expression. However, overcoming the low sialoadhesin expression at birth using in vivo prenatal exposures or treatments with inflammatory stimuli were not successful. The suppression of sialoadhesin expression by GBS–Siglec-E engagement may therefore contribute to disease pathogenesis in newborns and represent a challenging but potentially appealing therapeutic opportunity to augment immunity at birth.
Generalized Linear Modeling of Rotorcraft Acoustic Flight Test Data
Authors:   US Army CCDC AvMC, Stephenson James
Published: May 2024

The application of generalized linear modeling to rotorcraft acoustic emission data from an extensive flight test has been explored. The flight test data has 632 runs with at least 21 microphones measuring each run. The data was reduced to the maximum measured value for six acoustic metrics of interest, which are treated as the response variables in the modeling effort. Two sets of predictor variables were chosen, a dimensional set (true airspeed, gross weight, and flight path angle) and a non-dimensional set (advancing side tip Mach number, advance ratio, coefficient of weight, and wake skew ratio). It was shown that several of the predictor and response variables were not normally distributed, necessitating generalization of the linear models. A total of 19 different models were developed and analyzed, eight models were built from dimensional parameters and 11 from non-dimensional parameters. It was shown that the cubic version of the dimensional parameter model, which favors gross weight as a driving parameter, predicted the data set the best for all acoustic metrics. It was found that the response variables were from locations primarily directly beneath the vehicle, resulting in a predisposition towards modeling loading noise effects.
Frequency Domain gappy-POD for Rotor Acoustic Measurement Optimization
Authors:   University of Texas at Austin, Tinney Charles , Zhao-Dubuc Yingjun , Valdez John
Published: May 2024

This paper describes a mathematical framework for determining the optimal sensor set location for adequately capturing the sound generated by rotors. The approach leverages the gappy-POD method proposed by Everson and Sirovich [J. Opt. Soc. Am., Vol. 12, 1995, pp. 1657-1664], which first identifies the various mode constituents that make up the first few rotor blade-pass frequency harmonics of the sound-field. The algorithm is developed using a covariance matrix for the POD problem comprising auto- and cross-spectral densities of spatially and temporally resolved sound waves captured by an array of microphones oriented parallel to the axis of a laboratory-scale hovering rotor. Three different forms of the technique are developed and compared. These comprise a homogeneous form and two heterogeneous forms; the heterogeneous forms are referred to as XX-topos and XX-chronos and depends on which term in the error minimization equation is assigned the gappy sensor set. A greedy algorithm is then employed to determine the optimal location of the limited sensor set. The findings are analyzed for different combinations of POD modes and blade-pass frequency harmonics of the sound generated by the hovering rotor.
Numerical Aeroacoustic Simulation of Shrouded and Unshrouded Coaxial Rotors

In the context of developing new rotorcraft dedicated to Advanced Air Mobility, the use of non-conventional propulsive systems such as coaxial counter-rotating rotors, equipped or not with a shroud, is often addressed. The present numerical study falls into this framework. We actually propose to analyse the noise generated by such configuration in stationary conditions with a direct noise simulation realized thanks to a lattice Boltzmann Method. In a first step, the predictions are validated by comparisons with measurements realized in an anechoic chamber for the unshrouded case. A good agreement is observed on both tonal and broadband components of the noise radiated by the propulsive system. Then, the effects of using a shroud around the rotors are investigated numerically. It appears that the use of the shroud significantly increases the relative importance of the broadband noise because of interactions between turbulent wakes with the rear propeller and the duct surface. One can consequently conclude that employing a shroud is not necessarily a good option and this architectural choice must be made carefully. Finally, the impact of the rotor-rotor distance is analysed in both cases with and without shroud. As expected, increasing the distance allows reducing the noise levels but this effect seems to be limited to the tonal noise with almost no impact on the broadband component. Those observations are still valid when the duct is used, but placing the front rotor closer to the shroud inlet makes the shrouded configuration even louder. In a near future, this study will be completed by a complementary test campaign that will allow more validations of the present simulations and confirm or not the resulting conclusions.

Published: May 2024

This study examines the acoustics of a wing operating in the wake of a propeller. The propeller wing system is simulated at 24 knots cruise and 8° wing angle of attack. The propeller is simulated using an actuator line model, while the wing is simulated using two different turbulence models: a DDES turbulence model and a higher fidelity LES model. Chordwise compact loads, on-wing pressure surfaces, and pressure surfaces at distances of 2.34% and 10% thickness around the wing surface are used as inputs to PSU-WOPWOP to predict noise at an observer below the wing. Using on-wing surface pressures, the LES broadband noise predictions are 13.5 dB higher than DDES. Chordwise compact loads result in lower noise predictions than on-wing surface pressures, by 11.3 dB for LES and 2.3 dB for DDES. Using off-body pressure surfaces, DDES results remain similar to noise predictions from on-wing pressure surfaces, but with LES the broadband noise predictions are about 2.5 dB lower.
The unusual connection between Right-Sided Aortic Arch and bronchial asthma
Authors: Scaramozzino Marco Umberto , Nassisi Veronica , Sapone Giovanni
Published: May 2024

This work describes a rare clinical case of anomalous positioning of the aortic arch in a female patient with asthma. It highlights literature suggesting that this anomaly may sometimes mimic bronchial asthma, underscoring the importance of conducting bronchodilator reversibility tests more frequently to identify underlying asthma. The patient, a woman presenting with asthma symptoms, was found to have a Right-Sided Aortic Arch (RSAA), which is an unusual finding in the absence of congenital heart disease. Given the rarity of this presentation, it underscores the need for thorough evaluation and consideration of alternative diagnoses in patients with atypical asthma symptoms. This case emphasizes the importance of comprehensive diagnostic approaches, including spirometry and bronchodilator testing, to accurately diagnose and manage patients with asthma-like symptoms associated with rare anatomical variations such as RSAA.

Published: May 2024

This article proposes the structure and algorithm to design a PID controller for
the driving wheel slip prevention system (DWSPs) of a dump truck using a diesel
engine, which is equipped just only with a traditional high-pressure pump (HPP)
under low-adhesion coefficient conditions. First, a longitudinal dynamic model,
and a dynamic model of the wheel and powertrain of a dump truck are,
respectively, established, and an experiment in the torque determination of a
diesel engine is set up to investigate longitudinal vehicle dynamics as well.
Then, a control system structure of the DWSPs for a dump truck using a diesel
engine with a high-pressure inline fuel pump is proposed. Finally, based on
performance analysis of other types of controllers, a PID controller is selected
to control actual load level of a diesel engine. The criteria representing the
vehicle’s acceleration such as the vehicle speed, vehicle acceleration, total
slip time, and time to reach vehicle speed are selected to examine the
effectiveness of the proposed controller when vehicles are being operated under
the road surface conditions with low values of adhesion coefficient. The
obtained results show that the proposed controller has greatly limited the
driving wheel slipping phenomenon and increased the acceleration of the original
dump truck. In addition, these findings can be used as a theoretical basis for
the improvement of the wheel slip controllers in trucks using diesel
engines.
