Agency, Inclusion and Political Mobilisation of Irregular Migrants
Authors: Ambrosini Maurizio , Hajer Minke H. J. 
Published: May 2023

AbstractThe literature on irregular migration often deals with migration policies and the role of states. A smaller body of literature focuses on the role that irregular migrants themselves have, or can have. This chapter will explore the agency that irregular migrants have to influence their own migration trajectory. Moreover, it will discuss how irregular migrants can use their agency to become incorporated into the societies in which they reside despite their irregular status. By using a broad notion of citizenship, we will consider how irregular migrants can use their agency to obtain forms of inclusion, other than through regularisations, and how they can have the capacity to trigger political and social change despite their irregular status. This chapter will elaborate on social movements of irregular migrants.

Developing a Water Demand Management Plan
Authors: Ong Corinne , Tortajada Cecilia , Arora Ojasvee 
Published: May 2023

AbstractA fit-to-context WDM plan can help inform water service providers how to achieve efficient water use and optimise existing water resources before contemplating the development of additional resources and infrastructure. Plans may incorporate WDM measures with clearly defined objectives, approach, potential outcomes, and timelines for implementation. On implementation, regular monitoring and assessments of WDM measures can ensure that they adapt to changing conditions and remain effective.

Published: May 2023

Abstract
Introduction
It is increasingly recognized that health-related quality of life (HRQoL) is a relevant outcome to study in populations comprising severely injured patients. Although some studies have readily demonstrated a compromised HRQoL in those patients, evidence regarding factors that predict HRQoL is scarce. This hinders attempts to prepare patient-specific plans that may aid in revalidation and improved life satisfaction. In this review, we present identified predictors of HRQoL in patients that have suffered severe trauma.

Methods
The search strategy included a database search until the 1st of January 2022 in the Cochrane Library, EMBASE, PubMed, and Web of Science, and reference checking. Studies were eligible for inclusion when (HR)QoL was studied in patients with major, multiple, or severe injury and/or polytrauma, as defined by authors by means of an Injury Severity Score (ISS) cut-off value. The results will be discussed in a narrative manner.

Results
A total of 1583 articles were reviewed. Of those, 90 were included and used for analysis. In total, 23 possible predictors were identified. The following parameters predicted reduced HRQoL in severely injured patients and came forward in at least more than three studies: higher age, female gender, lower extremity injuries, higher rate of injury severity, lower achieved educational level, presence of (pre-existing) comorbidities and mental illness, longer duration of hospital stay, and high level of disability.

Conclusion
Age, gender, injured body region, and severity of injury were found to be good predictors of health-related quality of life in severely injured patients. A patient-centered approach, based on individual, demographic, and disease-specific predictors, is highly recommended.

Published: May 2023

AbstractDC 53 steel has emerged as a possible replacement of AISI D2 steel possessing competitive hardness and better toughness. In the current work, turning of DC 53 steel was conducted via Xcel modified inserts by varying workpiece hardness levels (40 and 60 HRC), cutting speed (130 and 160 m/min), feed rate (0.07 and 0.112 mm/rev), and depth of cut (0.07 and 0.17 mm). A two-level 4-factor full factorial design was employed entailing 16 runs. An analysis of variance (ANOVA) was conducted to statistically analyze the effect and contributions of input parameters on response variables namely tool life, surface roughness, volume of material removed, power consumption, and machining zone temperature. Results show that the tool life, surface roughness, volume of material removed, and machining zone temperature are primarily affected by the hardness of DC53 with PCRs of ~ 96%, ~ 25%, ~ 62%, and ~ 25%, respectively. At a 40 HRC hardness value, true crater wear was observed due to continuous chips sliding at the rake face while for the workpiece having a 60 HRC, discontinuous chip formation produced less prominent crater wear. SEM images revealed complete delamination of the coating from the tool surface with adhesion and attrition wear identified as the main wear mechanisms. The formation of a groove pattern was also noticed on the flank face. The minimum surface roughness was 0.90 µm-Ra for the workpiece having a 40 HRC hardness level, and the same value was obtained for 60 HRC as well. The threshold value of the feed rate for the excellent performance of these inserts was less than 0.20 mm/rev. Additionally, the turning process proved to be productive for this material along with a lower surface roughness value in comparison to the wire EDM process.
Die neue WHO-Klassifikation der Kiefertumoren
Authors: Haefliger Simon , Baumhoer Daniel 
Published: May 2023

ZusammenfassungOdontogene Tumoren und Kiefertumoren umfassen ein breites Spektrum an Läsionen, darunter Neoplasien, hamartomatöse Veränderungen und Entwicklungsstörungen. Seit Anfang 2022 ist eine Beta-Version der 5. Auflage der WHO-Klassifikation für Kopf-Hals-Tumoren online verfügbar, die voraussichtlich Mitte 2023 auch als Printversion erscheinen wird. Konzeptionell hat sich im Vergleich zur 4. Auflage nicht viel verändert. Die Reihenfolge der Läsionen ist stringenter nach Dignität geordnet und die gleichen Tumoren werden nicht mehr in verschiedenen Kapiteln lokalisationsabhängig mehrfach beschrieben. Diagnostische Kriterien werden neu in „essential“ und „desirable“ zusammengefasst. Zusätzlich zu den klinischen Aspekten wird nun auch die Bildgebung miteinbezogen und die Klassifikation damit interdisziplinär. Vereinzelt sind auch neue Läsionen erstmals aufgeführt. Dieser Artikel gibt einen Überblick über die Neuerungen der neuen Klassifikation mit einem speziellen Fokus auf die Einteilung der fibroossären Kieferläsionen.
Material-specific high-order harmonic generation in laser-produced plasmas for varying plasma dynamics
Authors: Mathijssen Jan , Mazzotta Zeudi , Heinzerling Amelie M. , Eikema Kjeld S. E. , Witte Stefan 
Published: May 2023

AbstractWe present a new experimental setup for high-order harmonic generation in laser-produced plasmas, allowing the generation of coherent VUV and EUV light, as well as characterisation of the laser-produced plasmas by studying the emitted harmonics. We have successfully generated high-order harmonics in laser-produced Al, Ni, Ag, In, and Sn plasmas. Large differences in harmonic spectra and signal yields have been observed for these different targets. Harmonics up to order 25, corresponding to a wavelength of 62.4 nm and photon energy of 19.9 eV, have been measured with tin plasmas. Scanning laser parameters and delay between pump and fundamental laser pulses allows us to optimise the harmonic yield and observe the temporal dynamics of the laser-produced tin plasma.

AbstractOne hurdle in the development of zebrafish models of human disease is the presence of multiple zebrafish orthologs resulting from whole genome duplication in teleosts. Mutations in inositol polyphosphate 5-phosphatase K (INPP5K) lead to a syndrome characterized by variable presentation of intellectual disability, brain abnormalities, cataracts, muscle disease, and short stature. INPP5K is a phosphatase acting at position 5 of phosphoinositides to control their homeostasis and is involved in insulin signaling, cytoskeletal regulation, and protein trafficking. Previously, our group and others have replicated the human phenotypes in zebrafish knockdown models by targeting both INPP5K orthologs inpp5ka and inpp5kb. Here, we show that inpp5ka is the more closely related orthologue to human INPP5K. While both inpp5ka and inpp5kb mRNA expression levels follow a similar trend in the developing head, eyes, and tail, inpp5ka is much more abundantly expressed in these tissues than inpp5kb. In situ hybridization revealed a similar trend, also showing unique localization of inpp5kb in the pineal gland and retina indicating different transcriptional regulation. We also found that inpp5kb has lost its catalytic activity against its preferred substrate, PtdIns(4,5)P2. Since most human mutations are missense changes disrupting phosphatase activity, we propose that loss of inpp5ka alone can be targeted to recapitulate the human presentation. In addition, we show that the function of inpp5kb has diverged from inpp5ka and may play a novel role in the zebrafish.
Optimal allocation of demand response considering transmission system congestion
Authors: Neves Motta Vinicius , Anjos Miguel F. , Gendreau Michel 
Published: May 2023

AbstractThe increasing penetration of renewable energy sources in the electricity grid brings new operational challenges. This brings up the need for effective means to provide demand response in spite of its distributed nature throughout the grid. Aggregators can be created to manage a set of such demand response resources, but deciding how to allocate an aggregator’s resources is an important problem. One of the aspects that needs more attention is the impact of the transmission system on these decisions. In this paper, we propose a short-term optimization model for allocating demand response(DR) resources as well as generation resources to supply external demand that is offered after the scheduling decision is made. The DR resources will only be available for use after the scheduling decision is made. Finally, our work also considers the impact of congestion in the transmission system when allocating DR. We propose the use of a semidefinite relaxation to provide a good initial point to solve our model with the aim of guaranteeing that we will find an optimal solution. Results from numerical tests with the IEEE 96-RTS and the ACTIVSG500 test grids are reported. We found that DR resources mitigates congestion management, allowing the generators to supply more of the external demand that is offered. Besides that, we observe that using our proposed solution methodology, we were able to obtain optimal solution for both cases studies, which is not the case when solving the original formulation for the ACTIVSG500 grid.

Abstract
Objective
A volume coil with squared slots-end ring was developed to attain improved sensitivity for imaging of rat’s brain at 7 T.

Material and Methods
The principles of the high cavity resonator for the low-pass case and the law of Biot-Savart were used to derive a theoretical expression of $$B_1/i$$

. The slotted-end ring resonator showed a theoretical 2.22-fold sensitivity improvement over the standard birdcage coil with similar dimensions. Numerical studies were carried out for the electromagnetic fields and specific absorption rates for our coil and a birdcage coil loaded with a saline-filled spherical phantom and a digital brain of a rat.

Results
An improvement of the signal-to-noise ratio (SNR) can be observed for the slotted volume coil over the birdcage regardless of the load used in the electromagnetic simulations. The specific absorption rate simulations show a decrement for the digital brain and quite similar values with the saline solution phantom. Phantom and rat’s brain images were acquired at 7 T to prove the viability of the coil design. The experimental noise figure of our coil design was four times less than the standard birdcage with similar dimensions, which showed a 44.5% increase in experimental SNR.

Discussion
There is remarkable agreement among the theoretical, numerical and experimental sensitivity values, which all demonstrate that the coil performance for MR imaging of small rodents can be improved using slotted end-rings.
Equilibrium arrivals to a last-come first-served preemptive-resume queue
Authors: Breinbjerg Jesper , Platz Trine Tornøe , Østerdal Lars Peter 
Published: May 2023

AbstractWe consider a queueing system which opens at a given point in time and serves a finite number of users according to the last-come first-served discipline with preemptive-resume (LCFS-PR). Each user must decide individually when to join the queue. We allow for general classes of user preferences and service time distributions and show existence and uniqueness of a symmetric Nash equilibrium. Furthermore, we show that no continuous asymmetric equilibrium exists, if the population consists of only two users, or if arrival strategies satisfy a mild regularity condition. For an illustrative example, we implement a numerical procedure for computing the symmetric equilibrium strategy based on our constructive existence proof for the symmetric equilibrium. We then compare its social efficiency to that obtained if users are instead served on a first-come first-served (FCFS) basis.
Soft tissue displacement for detection of left ventricle apical dyskinesis with transthoracic echocardiography
Authors: Schwartz Brandon H. , Tamarappoo Balaji K. , Shmueli Hezzy , Siegel Robert J. 
Published: May 2023

AbstractWe tested the hypothesis that the use of outward displacement of the soft tissue between the apex and the chest wall as seen in TTE, is a sign of apical displacement and would allow for more accurate diagnosis of apical dyskinesis. This is a retrospective study of 123 patients who underwent TTE and cardiac magnetic resonance imaging (MRI) within a time frame of 6 months between 2008 and 2019. 110 subjects were deemed to have good quality studies and included in the final analysis. An observer blinded to the study objectives evaluated the echocardiograms and recorded the presence or absence of apical dyskinesis. Two independent observers evaluated the echocardiograms based on the presence or absence of outward displacement of the overlying tissue at the LV apex. Cardiac MRI was used to validate the presence of apical dyskinesis. The proportion of studies which were identified as having apical dyskinesis with conventional criteria defined as outward movement of the left ventricular apex during systole were compared to those deemed to have dyskinesis based on tissue displacement. By cardiac MRI, 90 patients had apical dyskinesis. Using conventional criteria on TTE interpretation, 21 were diagnosed with apical dyskinesis (23.3%). However, when soft tissue displacement was used as the diagnostic marker of dyskinesis, 78 patients (86.7%) were diagnosed with dyskinesis, p < 0.01. Detection of displacement of soft tissue overlying the LV apex facilitates better recognition of LV apical dyskinesis.

Published: May 2023

AbstractSharing research data between researchers is becoming a requirement for open science in the field of clinical phonetics and speech and language pathology. An initiative entitled DELAD was started in 2015 to provide researchers a platform to discuss ongoing technical, legal and ethics issues related to sharing recordings of speech disorders, and to assist them in archiving their data for sharing with colleagues in the field. The ultimate goal of data sharing is to enhance research and teaching in the area of speech disorders. This paper first presents DELAD and its history and previous accomplishments. Then the recent work achieved by the DELAD steering group in providing information or recommendations in three areas are discussed: (1) speech annotation and automatic annotation mining, (2) consent and data storage, and (3) a role-play activity for learning data protection assessment. DELAD is an active community and researchers who share similar interests are welcome to join the (ad)venture.

Authors: Jibril Muhammad Attahir , Baumstark Alexander , Sattler Kai-Uwe 
Published: May 2023

AbstractHybrid transactional/analytical processing (HTAP) workloads on graph data can significantly benefit from GPU accelerators. However, to exploit the full potential of GPU processing, dedicated graph representations are necessary, which mostly make in-place updates difficult. In this paper, we discuss an adaptive update handling approach in a graph database system for HTAP workloads. We discuss and evaluate strategies for propagating transactional updates from an update-friendly table storage to a GPU-optimized sparse matrix format for analytics.
Digital competence of teachers in the use of ICT for research work: development of an instrument from a PLS-SEM approach

Published: May 2023

AbstractAll spheres of our life are being affected using technology, particularly its integration in the research processes carried out by teachers. The success of the integration of specific digital resources in research work can be affected by several factors, such as: digital skills for finding information, managing it, analyzing it, and communicating results; digital flow; anxiety in the use of ICT; digital ethics; quality of digital resources; and finally, the behavioral intention to integrate ICT. The purpose of this study is to examine the factors that influence the integration of ICT in the research process of the Higher Education teacher, and the relation between them. An online survey was used to collect data, and 1740 participants. This study used a causal model through partial least squares structural equations modeling (PLS-SEM). With this, the hypotheses established between the integration of ICT and its possible incident factors were verified. The findings revealed a significant influence path from factor integration to digital skills, ethics, flow digital, and behavior intention. Although, resource quality and ICT anxiety had significant effects on the causal model, they did not have a large impact on teachers’ integration of digital resources. The total of these factors corresponded to 48.20% of the variance in the integration of the researcher of the specific digital resources to be used in the research process. These results confirm that this model is effective in explaining the technological integration of teachers to use ICT in research work.
Unraveling the hydrogeochemical evolution and pollution sources of shallow aquifer using multivariate statistical analysis and hydrogeochemical techniques: a case study of the Quaternary aquifer in Beni Suef area, Egypt

Published: May 2023

AbstractThis study integrates multivariate statistical analysis and hydrogeochemical modeling to investigate the processes controlling the groundwater composition of a shallow aquifer where increased pumping rates and anthropogenic impacts were prevalent. Eighteen groundwater samples were collected and analyzed for major elements and selected heavy metals. The data were classified on the basis of multivariate statistical analysis into three clusters: C1 (Na-Cl facies), C2 (Ca-SO4 facies), and C3 (Ca-HCO3 facies). The application of factor analysis gave four factors affecting the groundwater chemistry, namely the salinization factor, anthropogenic/secondary enrichment factor, the secondary and the micro-nutrient fertilizers, and the aluminum fertilizer factor. The hydrogeochemical study of the groundwater revealed that the processes controlling the groundwater chemistry in the study area are mainly affected by the groundwater occurrence either to the east or to the west of Bahr Youssef Canal. Generally, the dominant hydrogeochemical processes affecting the groundwater are silicate weathering, ion exchange, irrigation return flow, gypsum applications in soil, and evaporation. The groundwater quality evaluation shows that water quality varies from fair to excellent for drinking purposes, where the best water is located in the northern and central parts of the study area. The suitability of groundwater for irrigation was evaluated using several indices indicating that groundwater is suitable for irrigation in the northwest and western parts of the study area. As some groundwater samples lie in high salinity classes on the US Salinity diagram, it is recommended to use this water for plants with good salt tolerance under good drainage conditions. The integration between the statistical and geochemical tools helps reveal the dominant processes through data reduction and classification.
