Authors: Hu Linqiang , Lei Wanjun , Xiao Zhongxiu , Sun Xing 
Published: June 2024

AbstractFinite control set model predictive control (FCS‐MPC) has been widely used in the control of three‐phase voltage source converter (VSC), but its control performance declines sharply at low sampling frequencies. This paper proposes an optimal control set expansion method with slip window selection and online parameter modification to improve the performance and robustness of FCS‐MPC. First, the performance of different control set expansion methods is compared. Then, an optimal control set expansion method that carries 12 virtual vectors is proposed. Last, a slip window selection strategy and an online parameter modification algorithm are proposed to reduce the computational burden and improve the controller's robustness respectively. Experimental result show that the proposed method significantly improves the control accuracy and carries good robustness and anti‐disturbance ability. Compared with existing typical MPC strategies, the proposed method obtains better current quality with lower switching frequency and requires less calculation. Moreover, the design of the proposed method is simple and there is no weighting factor to be tuned, which increases the method's practicality.

Published: June 2024

AbstractDue to the energy storage lifetime effects of the power allocation, there is a large space to improve the economy of the electric‐hydrogen hybrid DC microgrid. This paper provides an optimal control method based on the mutual learn salp swarm algorithm (MLSSA) in real‐time, which aims to enhance the economy and extend the system's service life. In order to realize the economic operation, operation cost and degradation cost of battery and hydrogen system are considered as the objective function first. Then, salp swarm algorithm based on mutual learn strategy is introduced to obtain optimal economy power allocation results in real‐time with higher convergence speed and increased accuracy. In addition, the proposed method also maintains the battery state of charge (SOC) and state of hydrogen charge (SOHC) within a proper range to guarantee the stable operation of the system. Finally, the results including power results, cost analysis and degradation rate analysis of the MATLAB/Simulink show that the proposed method is more economically beneficial than the non‐considering degradation cost strategy.

Emotion recognition has been the subject of extensive research due to its significant impact on various domains, including healthcare, human-computer interaction, and marketing. Traditional methods of emotion recognition rely on visual cues, such as facial expressions, to decipher emotional states. However, these methods often fall short when dealing with individuals who have limited ability to express emotions through facial expressions, such as individuals with certain neurological disorders.This research paper proposes a novel approach to emotion recognition by combining facial expression analysis with electroencephalography (EEG) data. Deep learning techniques are applied to extract features from facial expressions captured through video analysis, while simultaneously analyzing the corresponding EEG signals. The goal is to improve emotion recognition accuracy by utilizing the complementary information offered by the interaction between facial expressions and EEG data.Emotion recognition is a challenging task that has collected considerable recognition in the current years. Different and refined approaches to recognize emotions based on facial expressions, voice analysis, physiological signals, and behavioral patterns have been developed. While facial expression analysis has been a dominant approach, it falls short in instances where individuals cannot effectively express emotions through their faces. To overcome these limitations, there is a need to explore alternative methods that can provide a more accurate assessment of emotions. This research paper aims to investigate the collaboration and interaction between facial expressions and EEG data for emotion recognition. By combining the information from both modalities, it is expected to augment the accuracy and strength of emotion recognition systems. The proposed method can range from conducting literature reviews to designing and fine-tuning deep learning models for feature extraction, developing fusion models to combine features from facial expressions and EEG data, performing experimentation and evaluation, writing papers and documentation, preparing presentations for dissemination, and engaging in regular meetings and discussions for effective collaboration. Ethical considerations, robustness and generalizability, continual learning and skill development, and utilizing collaboration tools and platforms are also essential contributions to ensure the project’s success.
Update on the Use of Thrombopoietin-Receptor Agonists in Pediatrics
Authors: Gebetsberger Jennifer , Streif Werner , Dame Christof 
Published: June 2024

AbstractThis review summarizes the rationale and current data on the use of thrombopoietin receptor agonists (TPO-RAs) for treating severe thrombocytopenia in infants, children, and adolescents. It focuses on substances that have been approved by the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) for pediatric patients. Romiplostim and eltrombopag are already established as second-line treatment for persistent or chronic immune thrombocytopenia (ITP). As in adults, TPO-RAs are currently also evaluated in severe aplastic anemia (SAA), chemotherapy-induced thrombocytopenia (CIT), myelodysplastic syndromes (MDS), and poor engraftment after hematopoietic stem cell transplantation in pediatric and adolescent patients. Moreover, studies on the implication of TPO-RA in treating rare inherited thrombocytopenias, such as Wiskott-Aldrich syndrome (WAS), congenital amegakaryocytic thrombocytopenia (CAMT), or MYH9-associated thrombocytopenia, deserve future attention. Current developments include testing of avatrombopag and lusutrombopag that are approved for the treatment of thrombocytopenia associated with chronic liver disease (CLD) in adult patients. In pediatric and adolescent medicine, we expect in the near future a broader use of TPO-RAs as first-line treatment in primary ITP, thereby considering immunomodulatory effects that increase the rate of sustained remission off-treatment, and a selective use in rare inherited thrombocytopenias based on current clinical trials.

Systemische Sklerose
Authors: Biedermann Sophie , Riemekasten Gabriela 
Published: June 2024

ZusammenfassungDie Systemische Sklerose (Synonym: systemische Sklerodermie) ist eine nicht
heilbare Autoimmunerkrankung mit einem hohen Einfluss auf die Lebensqualität und
die Morbidität der Patienten. Sie zählt zu den Kollagenosen und ist
gekennzeichnet durch eine generalisierte Mikroangiopathie, die Produktion von
Autoantikörpern und durch Dysfunktion der Fibroblasten, die zu erhöhter
Produktion von extrazellulärer Matrix führt. Neben der Hautbeteiligung mit
akralen Ulzerationen und Autoamputationen kann eine Beteiligung der inneren
Organe wie Lunge, Herz, Gastrointestinaltrakt und Niere vorkommen. Die
Haupttodesursachen stellen die interstitielle Lungenerkrankung, die
pulmonal-arterielle Hypertonie und die kardiale Manifestation dar. Es besteht
eine Assoziation mit bestimmten antinukleären Antikörpern, die Pathogenese ist
bis heute noch weitestgehend unverstanden. Es gibt derzeit erste Ansätze,
Krankheitsmechanismen und die Beziehung zwischen der obliterativen Vaskulopathie
und der Fibrose zu verstehen. Die Therapie sollte so frühzeitig wie möglich im
Krankheitsverlauf beginnen und ist je nach Organbefall eine Kombination aus
Immunsuppressiva, antifibrotischer oder vasodilatativer Therapie.
Süßstoffe und ihre Wirkung auf das Körpergewicht
Authors: Kabisch Stefan 
Published: June 2024

ZUSAMMENFASSUNGSüßstoffe sind chemisch, geschmacklich und biologisch heterogene, hochpotente Süßungsmittel, die in kalorienreduzierten Getränken, hochprozessierten Speisen und diätetischen Ersatzmahlzeiten verwendet werden. Maximal empfohlene Verzehrsmengen (“acceptable daily intake”, ADI) werden bei ausgewogener Ernährung und bei ausgeprägter Nutzung trotz konservativer Auslegung meist nicht erreicht. Süßstoffmischungen begünstigen die Unterschreitung der ADIs und die Geschmacksoptimierung. Epidemiologisch ist Süßstoffverzehr mit Adipositas, Typ-2-Diabetes, kardiovaskuläre Erkrankungen und Krebs assoziiert. Starke Confounder (andere Lebensstilfaktoren) und „reverse causality“ schwächen aber die Aussagekraft.In verblindeten randomisiert-kontrollierten Studien (RCTs) bewirken Süßstoffe gegenüber Zucker eine signifikante Reduktion von Körpergewicht und Leberfett, während glykämische Parameter zum Nachteil trenden. Der Gewichtsverlust liegt unter der Erwartung gemäß der theoretisch eingesparten Kalorien. Psychologische oder metabolische Störeffekte der Süßstoffe sind daher aktuell Gegenstand intensiver Forschung, bei der das Inkretinsystem, die Konditionierung auf Süßreize und das Darmmikrobiom Ansatzpunkte darstellen.
Uroperitoneum bei einem weiblichen Jungrind

Published: June 2024

ZusammenfassungBei weiblichen Jungrindern ist ein Uroperitoneum ein selten dokumentierter
Befund. Häufiger ist es bei männlichen Jungrindern als Folge einer obstruktiven
Urolithiasis oder einer Urachitis bzw. eines Urachusabszesses beschrieben. In
diesem Bericht wird der Fall eines Uroperitoneums infolge einer vermutlich
traumatisch bedingten Harnblasenruptur bei einem 8,5 Monate alten weiblichen
Jungrind geschildert. Das Tier zeigte zum Zeitpunkt der Einlieferung in die
Klinik ein hochgradig vermehrt gefülltes Abdomen bei erstaunlicherweise
vorhandenem Harnabsatz. Bei der Palpation des Abdomens konnte eine deutliche
Undulationswelle ausgelöst werden. Es lag zudem eine begleitende
Labmagenverlagerung nach links vor. Auf eine ultrasonografische Untersuchung und
eine Bauchhöhlenpunktion folgte eine diagnostische Laparotomie. Der Harn wurde
fraktioniert aus der Bauchhöhle abgelassen, der geschädigte Harnblasenpol
abgesetzt und die Harnblase verschlossen. Der Labmagen wurde reponiert und
omentopexiert. Das Jungrind konnte geheilt entlassen werden und befand sich 5
Jahre später noch in der Herde.
The Lateral Wall of the Inferior Meatus as a New Graft Source for Rhinoplasty: Radiological Study and Surgical Technique

Published: June 2024

AbstractGenerally, revision rhinoplasty cases require the use of stiff grafts to restore the lost support. However, the majority of patients indicated for revision surgery present with a lack of a bony cartilaginous framework of the septum, especially after previous septoplasty. Thus, surgeons are compelled to harvest costal cartilage. At the same time, rib graft harvesting is associated with additional trauma and a risk of serious complications. Being ENT surgeons, we often resect a part of the lateral wall of the inferior nasal meatus during the extended endoscopic approach to the maxillary sinus. We supposed that this bone plate could be used as a donor site for rhinoplasty graft harvesting. The aim of our study was a radiological assessment of the feasibility and limits of using the inferior meatus lateral wall (IMLW) as a donor site for rhinoplasty bone graft.A retrospective evaluation of 100 CT scans of sinuses was conducted. Further measurements of the IMLW were performed: average length and width (28.06 ± 4.03 mm and 19.73 ± 3.08 mm, respectively), thickness (0.62 ± 0.21 mm), and average deviation from the sagittal plane (17.7 ± 9.53 degrees). According to the obtained measurements, the described donor site is appropriate for harvesting nice straight bony fragments.The IMLW bone graft was used in four revision rhinoplasty cases. There were no postoperative complications. During the long-term follow-up, patients reported significant improvement in aesthetics, function, and social aspects according to Rhinoplasty Outcome Evaluation. Thus, the described technique is an easy and safe method for bone harvesting for revision rhinoplasty. Our first experience demonstrated the convenience and stability of IMLW grafts for revision rhinoplasty during the follow-up period of up to 2 years.

Abstract
Objectives While clinical practice guidelines recommend that oncologists discuss goals of care with patients who have advanced cancer, it is estimated that less than 20% of individuals admitted to the hospital with high-risk cancers have end-of-life discussions with their providers. While there has been interest in developing models for mortality prediction to trigger such discussions, few studies have compared how such models compare with clinical judgment to determine a patient's mortality risk.
Methods This study is a prospective analysis of 1,069 solid tumor medical oncology hospital admissions (n = 911 unique patients) from February 7 to June 7, 2022, at Memorial Sloan Kettering Cancer Center. Electronic surveys were sent to hospitalists, advanced practice providers, and medical oncologists the first afternoon following a hospital admission and they were asked to estimate the probability that the patient would die within 45 days. Provider estimates of mortality were compared with those from a predictive model developed using a supervised machine learning methodology, and incorporated routine laboratory, demographic, biometric, and admission data. Area under the receiver operating characteristic curve (AUC), calibration and decision curves were compared between clinician estimates and the model predictions.
Results Within 45 days following hospital admission, 229 (25%) of 911 patients died. The model performed better than the clinician estimates (AUC 0.834 vs. 0.753, p < 0.0001). Integrating clinician predictions with the model's estimates further increased the AUC to 0.853 (p < 0.0001). Clinicians overestimated risk whereas the model was extremely well-calibrated. The model demonstrated net benefit over a wide range of threshold probabilities.
Conclusion The inpatient prognosis at admission model is a robust tool to assist clinical providers in evaluating mortality risk, and it has recently been implemented in the electronic medical record at our institution to improve end-of-life care planning for hospitalized cancer patients.
Colon Cancer and Pregnancy
Authors: Sacks Olivia A. , Davids Jennifer S. 
Published: June 2024

AbstractAs the incidence of colorectal cancer (CRC) in the younger population increases and women start their childbearing journey at later ages, CRC in pregnancy will become an increasingly relevant and decreasingly rare occurrence. Unfortunately, there is a dearth of data on this subject given its historical rarity. CRC is often diagnosed at a late stage in pregnancy because of the conflation of symptoms of pregnancy with symptoms of CRC. A major branch point for the diagnosis and treatment of CRC in pregnancy is whether it is diagnosed early or late in pregnancy. The workup for cancer is similar for pregnant and nonpregnant populations and includes endoscopy and staging computed tomography. Treatment is dependent on the stage of cancer and term of pregnancy. This review summarizes the current evidence for diagnosis, workup, and treatment of CRC during pregnancy and explores issues of fertility after a diagnosis of CRC.
A look at, inside, and outside metaphors
Authors: Colston Herbert L. 
Published: June 2024

Abstract
How metaphors are comprehended and their pragmatic effects have long been of interest (Colston, 2019; Gibbs, 2017; Gibbs & Colston,
2012). Attending to the varied constructions where metaphors appear has also advanced our understanding (Athanasiadou, 2017). How metaphors in extra-linguistic mediums has been of particular interest of late, as have the
import of embodied simulations (Bergen, 2012; Cienki &
Muller, 2008; Forceville & Urios-Aparisi, 2009). But these explorations outside of
language and inside the body have left some bits relatively unattended. Metaphors and their host constructions can be embedded into an array
of language genres. These also bring their own idiosyncratic influences on metaphor cognition. Moreover, the target domain content that
metaphors invoke adds to this complex mixture. And metaphors can be layered within metaphors. This paper presents a tour of just some of the
immense fractalesque complexity invoked when we look at the full richness of metaphorical meaning.

Published: June 2024

Summary
In this case study, we identify themes related to cultural tourism experience in boutique and non-boutique heritage hotels in Queretaro City, Mexico to determine whether there are differentiating elements that could be useful as a competitive strategy. We did a content analysis using web scraping and supervised text mining techniques, allowing us to statistically analyze 1040 guest reviews collected on TripAdvisor from January 2016 to December 2019. We made and validated a codebook to identify and characterize cultural tourism experiences in Mexican heritage hotels. We found that the experience of escapism, the perceived quality, and authenticity are significant differentiating elements between boutique heritage hotels and non-boutique heritage hotels.

Spherically symmetric electrovac spacetimes in conformal Killing gravity
Authors: Barnes Alan 
Published: June 2024

Abstract
Recently Harada proposed a third-order gravitational theory for the derivatives of the metric. Mantica and Molinari showed that Harada’s theory may be recast into the form of Einstein’s field equations (EFEs) with an additional source term which is a second-order conformal Killing tensor. Accordingly they named the theory conformal Killing gravity. However, they overlooked the fact that all solutions of the new theory (except those satisfying EFEs) admit a non-trivial second-order Killing tensor. Harada derived an analog of the Schwarzschild solution. Recently Tarciso et al obtained a generalization of Harada’s vacuum solution analogous to the Reissner–Nordström solution. However, like Harada they assumed a restricted form for a static spherically symmetric metric. In this study the most general spherically symmetric static vacuum solution of Harada’s theory and its generalization with a Maxwell electromagnetic field as source were obtained. The validity of Birkhoff’s theorem for static spherically symmetric electrovac fields in conformal Killing gravity is investigated.

-invariant connections: Riemann versus Finsler
Authors: Voicu N , Elgendi S G 
Published: June 2024

Abstract
For a torsion-free affine connection on a given manifold, which does not necessarily arise as the Levi–Civita connection of any pseudo-Riemannian metric, it is still possible that it corresponds in a canonical way to a Finsler structure; this property is known as Finsler (or Berwald–Finsler) metrizability. In the present paper, we clarify, for four-dimensional SO(3)-invariant, Berwald–Finsler metrizable connections, the issue of the existence of an affinely equivalent pseudo-Riemannian structure. In particular, we find all classes of

Topological tight binding models on some non-trivial lattices: union of geometry, flat bands and topology
Authors: Devanarayanan Bharathiganesh 
Published: June 2024

Abstract
We introduce a topological tight binding model based on certain rules that we have formulated to study systems with certain non-trivial bulks. These rules allow us to study bulks that have twists and branching. We discuss certain cases in the SAB model with different number of bands, exhibiting several interesting physical properties. For every bulk there can be two sets of configurations: the orientable and the non-orientable configuration. The later exhibits several non-trivial physical properties like exact flat bands (exactly at particle hole symmetry level), zero energy states localised in the bulk, topological edge states etc. We then discuss a three band non-orientable SAB model which is easy to visualise. We also investigate the effects of disorder (both chiral symmetry preserving and breaking) in the non-orientable configurations hosting flat bands. We find for chiral symmetry preserving disorders, some of them (non-degenerate flat band) are robust to large disorders while others (degenerate flat band) exhibit an insulator to metal transition beyond certain critical disorder strength due to band gap closing as a result of the broadening of the zero energy states. For chiral symmetry breaking disorders, in both the cases the zero energy bulk states broaden and close the gap beyond certain critical disorder strength.

Published: June 2024

Abstract
Lu doped Hf0.5Zr0.5O2 (HZO) ferroelectric films were prepared on Pt/TiN/SiO2/Si substrate by chemical solution deposition method, and an interfacial engineering strategy for improving the ferroelectric property was explored by capping the Lu doped HZO films with a cerium oxide layer. Compared with the Lu doped HZO film without the CeO
x
coating layer, the Lu doped HZO film with the CeO
x
coating layer has a larger remanent polarization (2P
r = 34.72 µC cm−2) and presents weaker wake-up behavior, which result from the higher orthogonal phase ratio and the lower oxygen vacancy of the CeO
x
coated Lu doped HZO film. In addition, the CeO
x
coating can remarkably improve the fatigue resistance and retention performance of the Lu doped HZO films. It is hoped that the results can provide an effective approach for the realization of high-performance and highly reliable hafnium oxide based ferroelectric thin films.
