AbstractBackgroundSeborrheic dermatitis (SD) is a common chronic inflammatory skin disease. In recent years, significant progress has been made in the field of SD, but there has been no bibliometric research yet. This study aims to use bibliometric methods to analyze the current research status and hot topics of SD, to understand further the research trends and future development prospects in this field.MethodsRetrieve core literature on SD from the Web of Science database and conduct a detailed analysis using CiteSpace and VOSviewer software based on factors such as publication volume, countries (regions), research institutions, journals, authors, highly‐cited papers, and keywords.ResultsFrom 1996 to 2024, a total of 1436 publications were included in the bibliometric analysis. The number of publications has shown an increasing trend year by year. The USA is the leading country in this field of research. The University of California System is the primary research institution. The International Journal of Dermatology is the journal with the highest number of publications. The author Yang Won Lee has the highest number of publications, while the article “Seborrheic Dermatitis” (2004) by Gupta, A.K. has been cited the most. “Seborrheic dermatitis” is the most frequently occurring keyword. The main research hotspots and frontiers in SD are as follows: (1) The relationship between SD and other skin diseases is a popular research topic; (2) Malassezia and inflammation are current research hotspots in SD; and (3) Focusing on antifungal and anti‐inflammatory treatments for SD is the current frontier direction in this field.ConclusionThis study is a summary of the current status and hot trends of SD research, which helps clinical doctors and researchers quickly understand the insights and valuable information of SD research and provides reference for clinical decision‐making and finding future research directions.

Published: September 2024

AbstractObjectivesWe seek to describe the current practice pattern use of prothrombin complex concentrate (PCC) and fibrinogen concentrate (FC) in trauma patients.BackgroundTrauma‐induced coagulopathy (TIC) and endotheliopathy of trauma (EOT) contribute significantly to mortality from traumatic haemorrhage. FC, and 4‐factor PCC are potential treatments for EOT and TIC, respectively.Materials and MethodsWe obtained data from the Trauma Quality Improvement Program (TQIP) registry and identified patients who received either PCC or FC using procedural codes. We used descriptive statistics to characterise practice patterns of these products.ResultsThere were 6 714 002 total encounters within the TQIP from 2017 to 2022, of which 10 589 received PCC and 3009 received FC. Of the recipients, there were 35 that received both products. There were 44 that received both. The median age of PCC recipients was 77 (69–84) with 19 patients <15 years of age with the youngest being 2 years of age. There was a general upward trend in the number of facilities with documented use of PCC: 155/744, 168/766, 189/764, 206/780, 234/795, and 235/816, respectively. The median age of FC recipients was 57 (32–75) with 48 patients <15 years of age with the youngest being 1 year of age. There was a minor downward trend in the number of facilities that had documented use of FC: 55, 44, 39, 32, 38 and 40.ConclusionsThe administration of PCC and FC remains uncommon, although there appears to be an upward trend of PCC use. Most PCC use appeared to be for anticoagulation reversal in the setting of head trauma. Data guiding the use of these products are necessary as these products become more recognised as adjuncts to traumatic haemorrhage control.
The maltose‐related starch degradation pathway promotes the formation of large and spherical transitory starch granules
Authors: Liu Qingting , Zhou Yuan , Flores Castellanos Junio , Fettke Joerg 
Published: September 2024

SUMMARYPreviously, in Arabidopsis thaliana, we found atypical spherical starch granules in dpe2ss4 and dpe2phs1ss4. However, the mechanism of such abnormal morphogenesis is still obscure. By tracking starch granule length and thickness with leaf ageing, we reported that the starch granules in dpe2phs1ss4 gradually change to a spherical shape over time. In comparison, Col‐0 and the parental line ss4 did not exhibit macroscopic morphological alteration. In this study, firstly, we specify that the additional lack of DPE2 resulted in the gradual alteration of starch granule morphology over time. Similar gradual morphological alterations were also found in dpe2, mex1, and sex4 but not in the other starch degradation‐related mutants, such as sex1‐8, pwd, and bam3. The gradual alteration of starch morphology can be eliminated by omitting the dark phase, suggesting that the particular impaired starch degradation in dpe2‐ and mex1‐related mutants influences starch morphology. Secondly, we observed that spherical starch morphology generation was accompanied by prominent elevated short glucan chains of amylopectin and an increased amylose proportion. Thirdly, the interplay between soluble starch synthase 2 and branching enzymes was affected and resulted in the formation of spherical starch granules. The resulting spherical starch granules allow for elevated starch synthesis efficiency. Fourthly, the starch phosphate content at the granule surface correlated with the morphology alteration of the starch granules. Herewith, we propose a model that spherical starch granules, accumulated in mutants with a misbalance of the starch degradation pathway, are result of elevated starch synthesis to cope with overloaded carbohydrates.

Published: September 2024

Abstract
Water entry is a complex non-linear phenomenon which involves multiphase interaction, and has been of interest in various engineering fields. For example, high speed craft slamming in rough sea, where the craft is frequently launched off the wave and lands on the air-water interface at high impact velocity. Lately, with the use of lightweight material such as composites, makes the effects of hydro elasticity even more crucial for the structural design of the craft. Although there are existing design codes for the design of high speed crafts by various classification societies but this complex phenomenon is not yet incorporated and need to be accessed via direct calculations. In this paper, the effects of hydro elasticity on the composite plate are studied using computational methods. The results from the experimental study of “Free-Falling Wedge with the composite bottom plate” conducted by Javaherian et al. were used for the numerical validation. The computational fluid dynamic model with fluid structure interaction was used to replicate the experimental setup with pressure and displacement probes located in accordance with the experimental design. The magnitude of pressure and displacements of the bottom flexible plate obtained from the numerical model were compared with the experimental data. To study the effects of fluid-structure interaction a nondimensional number RF, quantifying the hydro elasticity of the wedge plate, proposed by Faltinsen was used. Values of RF less than 2 are considered flexible and the fluid pressure is modified due to the structural deflection. The RF value for the flexible composite plate calculated in this study was 0.2.
Just-In-Time and Iterative Learning in Thermo-Fluids
Authors: Milanovic Ivana , Kumar Sunil 
Published: September 2024

Abstract
We examine the use of simulations as a tool for both just-in-time learning and iterative and integrative learning processes. Specifically, we investigate the utility of the simulation assignments and their lineup in fluid mechanic course on the improvement of student comprehension, retention of material, and critical thinking.
Simulation assignments were added to the list of student deliverables in the undergraduate lecture-based thermo-fluids courses almost a decade ago. They have been designed as weekly projects with an inquiry-based component, thus moving students from structured to unstructured tasks. This approach brought the digital engineering process into the curriculum, increased the average study time, provided students with opportunities to explore modern topics with modern tools, and enabled industry certification in simulation technology.
Appropriately designed and delivered simulation assignments accomplish the following goals simultaneously. They (1) enable students to acquire both knowledge and skills at the moment of need untethered from the classroom; (2) deliver relatable and visually exciting materials that keep learners engaged; (3) improve understanding of theory while going beyond the relatively simple pencil & paper problems, and (4) revisit difficult concepts multiple times over the semester and examine them from a different perspective.
Our results are illustrated with qualitative and quantitative evidence. Qualitative data provide samples of student work while quantitative assessments include grades, surveys, and course evaluations.
Effects of Aspect Ratio on Asymmetric Wake Flow Structure Around Right-Trapezoidal Prisms
Authors: Guney Aleyna , Abdul-Salam Fati Bio , Sagharichi Amir , Tachie Mark F. 
Published: September 2024

Abstract
In this paper, the turbulent flow characteristics around right-trapezoidal prisms with varying streamwise aspect ratios (AR, ratio of upper length to prism height) of AR = 0.6, AR = 2, and AR = 2.5 in a uniform flow were investigated using particle image velocimetry (PIV). The Reynolds number (based on the free-stream velocity and body height) is Reh = 10000, and the results are analyzed in terms of the mean velocities, Reynolds stresses, and probability density function (PDF). The results show that two recirculation bubbles form in the wake region of all prisms. The bubbles are asymmetrical, with the upper recirculation bubble larger than the lower one. For the AR = 2.5, an additional bubble is observed on the upper surface of the prism. Contours of the streamwise Reynolds normal stress show dual peaks, which are located above and below the centerline in the wake region. The magnitude of the peak above the centerline is comparably higher for AR = 2.5 than for AR = 0.6 and 2.0. Conversely, the vertical Reynolds normal stress shows a single peak with increasing magnitude as the aspect ratio rises. Regardless of aspect ratio, the PDF of streamwise fluctuating velocity displays an unimodal distribution, while vertical velocity fluctuation shows a bimodal distribution at the point of maximum vertical fluctuating velocity.

Published: September 2024

Abstract
Vortex-induced vibration (VIV) is currently extensively studied as a potential method for small-scale piezo-electric energy harvesting. Here, we experimentally investigated the parameters that influence VIV of a vibrating cylinder attached to a cantilever beam. This paper is primarily focused on investigating the range of airflow velocities that can induce system vibrations, quantifying the maximum amplitudes of vibration, and determining the critical airflow velocities at which vibrations reach their maximum. These investigations are conducted while systematically varying key system parameters, including mass, stiffness, and cylinder diameter. Some of the key-findings of this research include that larger cylinder diameters lead to greater vibration amplitude and broader operating bandwidths. Furthermore, an increase in system mass results in a reduction in the bandwidth of vibration, while greater system stiffness enhances both the maximum amplitude of vibration and the overall bandwidth. Since vibration amplitude is directly related to power production for piezoelectric harvesters, the findings in this research contribute to a better understanding of the VIV energy harvesters, validate many modeling efforts, and offer practical guidelines for enhancing their efficiencies. These findings open new opportunities for sustainable energy generation through the exploitation of ambient fluid-induced vibrations in various practical applications.
Study of the Flow Around a High Voltage Battery Module to Be Applied in Leak Testing
Authors: Sleight Matthew , Adami Stefan , Indinger Thomas 
Published: September 2024

Abstract
The air tightness of the High Voltage (HV) battery housing in the automobile industry protects the battery from adverse elements in the environment such as pressure, temperature changes and the appearance of moisture in the housing. A quality control process occurs on the production line and is a mandatory step for every battery produced. An optimized process will save time and costs. The process will use the Massflow method in order to measure the leakrate. It consists of using air under pressure to analyse the leakrate of the studied volume. Non-negligible impacting factors of this method are the different modules placed in the battery itself. The modules impact the process because of their geometry and their own leakage as they have an internal volume. To improve the method, an efficient way to study the process is to use a numerical model.
The numerical model was of a single module that was tested numerically and experimentally in order to validate the numerical method. In addition it was used to identify some first improvements in the quality of the testing.
To create the numerical model, the Smoothed Particles Hydrodynamics (SPH) method was used. This method uses a Lagrangian point of view to tackle the simulation, meaning the fluid is discretized into several particles that interact together. In order to validate the use of this model, it was compared with an experiment. To observe the flow around a module and validate the model, a setup was created in which the battery module was put in a box where the pressure can be controlled and monitored. A digital twin of this setup was created that allows the visualization and the study of the flow around the module when a pressure change occurs at an inlet of the box.
The goal of these studies is to examine the stabilization of the flow around the module: how the geometry of the module, the geometry of the testing box or the air supply can affect a fast stabilization in the properties of the flow. The research focuses on improving the airflow in the testing box. To do this, the spot where the pressure stabilizes the latest is determined and then solutions identified to improve its stabilisation. Numerous solutions were investigated like the change of geometry but also the placement or number of the exchange cables.
In the future, this research will study the flow surrounding the module and identify the specific areas that will have to be investigated in a full battery housing setup. As a consequence, this will improve the quality control process in the production of HV batteries.
Flexible Fibres in Wall-Bounded Turbulence
Authors: Di Giusto Davide , Dhas Darish Jeswin , Marchioli Cristian 
Published: September 2024

Abstract
We study the dynamics of flexible fibres in turbulent channel flow by performing DNS in an Euler-Lagrange framework. We use the rod-chain model to construct fibres by linking sub-Kolmogorov rods. Jeffery [1] gave the expression describing the rotation executed by ellipsoids suspended in a viscous simple shear flow devoid of fluid inertia. We use Jeffery’s expression to calculate the orientation of the suspended rods. In addition, to account for the role of the fluid inertial forces and torques, we use the model by Dabade et al. [2]. Subsequently, we perform a set of direct numerical simulations of a fibre-laden channel flow whose shear Reynolds number is 300, for a range of fibre parameters to specifically discern the effects of the fibre length, their flexibility characterised by their bending stiffness, and the inclusion of fluid-inertial forces and torques.
The Impact of Hydropower Development on Economic, Ecological, and Social Structures in Rural Norway During the Great Expansion Era 1945-1990
Authors: Fischer Markus , Lia Leif 
Published: September 2024

Abstract
This paper examines the impact of the development of hydropower resources on the economic, ecological, and social structures in two rural areas of Norway, Western Norway and Northern Norway, during the great expansion era for hydro-power capacity building in Norway, between 1945 and 1990. The data basis for the study is formed by newspaper articles from both regions, which reported on hydropower during the period under consideration. The evaluation of this data provides a clear and differentiated picture of the influences of hydropower development in these two parts of the country. It can be seen that both Western Norway and Northern Norway were affected by changes due to the progressing hydropower expansions. However, to varying degrees - in Western Norway, hydropower development has had a much greater impact than in Northern Norway. This is reflected in a higher number of newspaper articles from Western Norway that contain references related to economic, ecological, and social effects — such as reports on hydropower development in connection with the establishment of new industrial plants or new traffic infrastructure, as well as with changes in wildlife.
Furthermore, this study shows the potential of analyzing newspaper articles to better understand, evaluate, and tackle today’s challenges in the integration of renewable energy technologies worldwide.
Numerical Simulation of Leakage Noise Field for Solenoid Valve

Published: September 2024

Abstract
The solenoid valve is a vital actuator of the industry control system, directly affecting the security and reliability of the whole system. Consequently, it is very important to monitor the operating condition of the solenoid valve. Degradation of the solenoid valve is often manifested as leakage due to its high action frequency. However, the leakage is challenging to detect online. The common methods for online detection of leakage include ultrasonic detection and acoustic emission detection. Both have a relationship with the sound field. In this paper, on the basis of analyzing the noise mechanism of valve leakage flow, CFD fluid simulation and FW-H Acoustic Analogy Method is used to obtain the distribution of the flow field and sound field of the solenoid valve. The results show that: as the increase of pressure difference, the leakage rate and the acoustic power level become larger significantly and form vortices. A change in the shape of the leak hole can make changes in flow and sound fields, which should be taken into consideration in leak detection. Acoustic signals are generated through transient simulation and the FFT algorithm is applied to deal with the acoustic signals. The conclusion is drawn that the noise of the valve leakage is mainly distributed at the frequency of around 1500 Hz and represents frequency doubling. This work can provide a certain reference value for the inner leakage detection experiment of solenoid valves.
PTV-Based Measurement of a Local Flow Field in a Microfluidic Dragonfly Forewing Model
Authors: Zhang Haipeng , Ryu Sangjin 
Published: September 2024

Abstract
Wings are critical for insects, and blood flowing through wing veins is crucial for maintaining the function and integrity of insect wings. Insect wing circulation has been investigated by observing the motion of blood cells or injected microspheres through the veins of live insects. However, using live insects is limited in studying detailed local patterns of blood flow. To overcome the limitation, we developed a microfluidic replica of the forewing of a dragonfly (Common Green Darner; Anax junius) using a high-resolution picture of the wing, photolithography, and PDMS (polydimethylsiloxane)-based soft lithography. Phosphate buffered saline (PBS) with 20 μm-diameter polystyrene beads was steadily injected into the device. The movement of the beads in a region of interest with complicated vein geometries was imaged by high-speed video microscopy. Recorded images were processed using MALTAB-based particle tracking velocimetry (PTV) code to determine the local flow field. Our processed PTV result shows that overall flow direction was from the leading edge vein to the trailing edge vein of the wing, and from the wing base toward the wing tip. The flow directions in the region of interest were comparable to previous studies on blood circulation in dragonfly wing veins. This agreement supports our idea that microfluidic insect wing vein models can recreate the blood flow of corresponding wings in vitro and enable detailed investigation of the local flow field.

Abstract
Offshore wind energy has experienced significant growth as a thriving industry, owing to the abundance of wind resources available in the open ocean. However, unlike their onshore counterparts, offshore wind turbines face greater exposure to environmental hazards, particularly ocean sprays. These sprays pose three primary hazards to offshore wind turbines: erosion, corrosion, and icing, due to saline droplets impacting and interacting with turbine surfaces. The primary goal of this research is to develop an innovative droplet-absorption-based surface technology capable of mitigating the hazards posed by ocean sprays. In this paper, a comprehensive experimental study was conducted to characterize the dynamic behaviors of droplets interacting with various porous geometries with modulated porosity and pore sizes. A high-speed imaging system was used to observe and experimentally analyze the impinging and penetration dynamics of the droplets as well as the competing inertial and capillary effects as droplets travel through porous geometries. It was found that the droplets impacting on the porous surfaces display various dynamics, depending on the relative scales of the droplet size and the pore size. The pore geometries, e.g., shape, spacing, and arrangement, also contribute to the discrepancies in droplet impact and penetration dynamics. A porous surface with gradient pores is also developed, which shows great potential in promoting droplet penetration through the surface. The findings in this paper pave the way for the incorporation of droplet-absorption-based surface technologies on wind turbine blades, making offshore wind farms more resilient and productive in the pursuit of renewable energy sustainability.
