Oral Dexmedetomidine Achieves Superior Effects in Mitigating Emergence Agitation and Demonstrates Comparable Sedative Effects to Oral Midazolam for Pediatric Premedication: A Systematic Review and Meta-Analysis of Randomized Controlled Studies

Background: Oral midazolam is the most commonly used sedative premedication agent in pediatric patients. While effective, oral midazolam cannot reduce the incidence of emergence agitation. Oral dexmedetomidine may be effective in providing satisfactory sedation and reduce the incidence of emergence agitation, although the results of different randomized controlled trials are conflicting. Methods: This study enrolled randomized controlled trials (RCTs) examining premedication with oral dexmedetomidine versus oral midazolam in pediatric patients undergoing general anesthesia. PubMed, the Cochrane Library, Embase, and the Web of Science database were searched from their inception until June 2023. The outcomes were the incidence of satisfactory preoperative sedation, satisfactory sedation during separation from parents, satisfactory sedation during anesthesia induction using an anesthesia mask, and the incidence of emergence agitation. Results: A total of 9 RCTs comprising 885 patients were analyzed. Our data revealed comparable effects of dexmedetomidine and midazolam with respect to satisfactory preoperative sedation and a satisfactory incidence of sedation during parental separation and mask acceptance before anesthesia induction. Notably, our data revealed that the rate of emergence agitation was significantly lower in pediatric patients receiving dexmedetomidine (n = 162) than in those receiving midazolam (n = 159) (odds ratio = 0.16; 95% confidence interval: 0.06 to 0.44; p < 0.001; I2 = 35%). Conclusions: Data from this meta-analysis revealed comparable effects for premedication with oral dexmedetomidine or oral midazolam with respect to satisfactory sedation; furthermore, premedication with oral dexmedetomidine more effectively mitigated emergence agitation in pediatric patients receiving general anesthesia compared with oral midazolam.
Market Timing and Asymmetric Information: How do Rights Issues and Private Placements Attract Investors to Overvalued Stocks?

Manuscript type: Research paper Research aims: This study examines the background of selecting the equity offering mechanism between rights issues and private placements when facing asymmetric information and overvalued prices. Design/Methodology/Approach: This research employs the concept of information asymmetry and focuses on analysing market timing data about stock offering transactions in Indonesia from 2000 to 2020. This study uses regression analysis to examine the correlation between information asymmetry and trade volume. Abnormal trade volume before various offerings is subjected to regression analysis using generally used proxies for information asymmetry. Research findings: The conclusions of our research indicate that companies that issue more shares than the overpriced stock tend to exhibit a more excellent abnormal return value in the context of rights issues. The sales volume indicates the company’s prospects derived from private information obtained during the offering Theoretical contribution/Originality: There is a shortage of existing literature about research that specifically investigates the identification of SEO techniques that elicit negative market responses. Consequently, this study explores the connection between the underlying motivations driving the selection of stock offering mechanisms. Practitioner/Policy implication: The distribution of profits in the transaction indicates the company’s future policies. Before investing, investors can acquire pertinent information on the company’s current state, strategic goals, and prospects. Research limitation: The present analysis has not considered the factors of internal ownership or insider trading. These factors might serve as a foundation for investigating the underlying incentives for issuing shares with more precise market timing considerations.
Nutritional Status, Sex, and Ambient Temperature Modulate the Wingbeat Frequency of the Diamondback Moth Plutella xylostella

Simple Summary The diamondback moth, Plutella xylostella (L.), is an important migratory insect pest worldwide. In this study, the effects of environmental parameters, age, nutritional supplementation and sex on the wingbeat frequency of the insect adult were measured in the laboratory, and the results showed that nutritional status, sex and ambient temperature modulate the wingbeat frequency of the moth. These findings can be helpful for further understanding flight biology of the insect as well as to improve the accuracy using insect radar facility to directly identify migrating moths based on species difference of wingbeat frequency. Abstract The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), is a cosmopolitan horticultural pest that is undergoing a fast, climate-driven range expansion. Its wide geographic distribution, pest status, and high incidence of insecticide resistance are directly tied to long-distance migration. Wingbeat frequency (WBF) is a key aspect of P. xylostella migratory behavior, but has received limited scientific attention. Here, we investigated the effects of environmental parameters, age, adult nutrition, and sex on P. xylostella WBF. Across experimental regimes, WBF ranged from 31.39 Hz to 78.87 Hz. Over a 10–35 °C range, the WBF of both male and female moths increased with temperature up to 62.96 Hz. Though male WBF was unaffected by humidity, females exhibited the highest WBF at 15% relative humidity (RH). WBF was unaffected by adult age, but adult nutrition exerted important impacts. Specifically, the WBF of moths fed honey water (54.66 Hz) was higher than that of water-fed individuals (49.42 Hz). Lastly, males consistently exhibited a higher WBF than females. By uncovering the biological and (nutritional) ecological determinants of diamondback moth flight, our work provides invaluable guidance to radar-based monitoring, migration forecasting, and the targeted deployment of preventative mitigation tactics.
Calculation Method and Characteristic Analysis for Fault Current of Permanent Magnet Direct-Drive Wind Power System considering Positive and Negative Sequence Decomposition

In view of the fact that the influence of positive and negative sequence decomposition, which is widely used in positive and negative sequence decoupling control in control system, on the fault current calculation process is not deeply considered in the existing transient analysis methods of permanent magnet direct-drive wind farm short circuit current, this paper proposes a transient short circuit current calculation model that takes into account positive and negative sequence decomposition. The influence of the transient characteristics of positive and negative sequence decomposition on the control system is studied, and the mechanism of its action on the transient change of short circuit current is revealed. The positive and negative sequence decoupling processes of the circuit equation are modified, and the characteristics of the coupling equation are analyzed. The difference in the converter output voltage between the circuit equation and the control equation and the depth of its influence on the calculation process is revealed. On the basis of quantifying the difference at the converter output voltage, the circuit equation and the control equation are combined to form a short-circuit current calculation model with positive and negative sequence decomposition, which accurately characterizes the transient characteristics of fault current under different voltage drops and effectively improves the accuracy of the calculation results.
Evolution of the lithospheric mantle in NE Angola: implications for diamond exploration

Angola is currently the 8th largest diamond producer in the world, but for historical reasons the subcontinental lithospheric mantle (SCLM) in the Congo-Kasai craton is still poorly studied. However, an understanding of the structure, composition and evolution of this SCLM, as well as the properties of the kimberlitic magmas themselves, is essential for the future of diamond exploration. A detailed textural and compositional study of groundmass perovskite (CaTiO3) in 6 kimberlitic intrusions in the Lunda Norte province (NE Angola) revealed a complex, multi-stage process that involved mingling of compositionally different melts. U-Pb dating of perovskite yielded Lower Cretaceous ages (116-133 Ma), which suggests that kimberlite magmatism resulted from reactivation of deep-seated translithospheric faults (>300km) during the break-up of Gondwana. A layered structure of this SCLM was inferred from the characterisation of mantle xenoliths and xenocrysts sampled by the Cat115 and Catoca kimberlites. The layering is defined by two distinct garnet-peridotite suites, separated by a zone rich in low-Mg eclogite at ~150km depth. Two origins have been proposed to explain the current structure of the SCLM (stacking subduction vs plume upwelling), although more data are required to decide which is the most likely explanation. Complex metasomatic processes have modified the composition of an originally depleted SCLM. In the model proposed in this thesis, the shallow SCLM was firstly affected by silicate melt metasomatism, which resulted in the introduction of garnet (± clinopyroxene). Subsequently, carbonatite-silicate melts refertilised the deep SCLM, introducing both clinopyroxene and garnet. Percolative fractional crystallisation of these melts would explain the late formation -or cryptic metasomatism- of clinopyroxene with a carbonatitic signature, as well as the crystallisation of phlogopite, in the shallower layer of the SCLM, shortly prior to kimberlite eruption. Finally, interaction with the kimberlitic magma led to the crystallisation of a second generation of phlogopite and fine- grained pyroxene along fractures and grain boundaries. The results presented in this thesis highlight the complexity of the processes that took place in the SCLM in NE Angola and how these may have modified the composition of the diamond indicator minerals (ilmenite, clinopyroxene and garnet) sampled by the kimberlites. This is especially relevant in the case of ilmenite, since interaction with a kimberlitic magma may lead to misinterpretation of the diamond potential of a prospective kimberlite if textures and trace-element composition are disregarded.
Embryotoxic Effects of Pesticides in Zebrafish (Danio rerio): Diflubenzuron, Pyriproxyfen, and Its Mixtures

Diflubenzuron (DFB) and pyriproxyfen (PPF) are larvicides used in crops to control insect plagues. However, these pesticides are known to impact non-target organisms like fish and mammals. Here, we aimed at assessing the embryotoxicity of purified DFB, PPF, and their mixtures in a non-target organism—zebrafish. Zebrafish embryos were exposed to different concentrations for 120 h: 0.025, 0.125, 0.25, 1.25, 2.5, and 10 mg/L of purified PPF and purified DFB, while we used 0.025 mg/L PPF + 10 mg/L DFB (Mix A), 0.125 mg/L PPF + 10 mg/L DFB (Mix B), and 0.25 mg/L PPF + 10 mg/L DFB (Mix C) for the mixtures of PPF + DFB. We observed mortality, teratogenicity, and cardiotoxicity. For the neurotoxicity tests and evaluation of reactive oxygen species (ROS) levels in the brain, embryos were exposed for 120 h to 0.379 and 0.754 mg/L of PPF and 0.025 and 0.125 mg/L of DFB. We established the LC50 for PPF as 3.79 mg/L, while the LC50 for DFB was not determinable. Survival and hatching were affected by PPF concentrations above 0.125 mg/L, DFB concentrations above 1.25 mg/L, and the lower pesticide mixtures. PPF exposure and mixtures induced different types of malformations, while a higher number of malformations were observed for the mixtures, suggesting a potentiating effect. Pesticides diminished avoidance responses and increased the levels of ROS across all concentrations, indicating neurotoxicity. Our findings underscore the detrimental impact of PPF and DFB exposure, spanning from biochemistry to morphology. There is a critical need to reconsider the global use of these pesticides and transition to more ecologically friendly forms of pest control, raising an alarm regarding repercussions on human and animal health and well-being.
Distinguished representations : the generalized injectivity conjecture and symplectic models for unitary groups

Soit $G$ un groupe connexe quasi-deploye defini sur un corps non-Archimedien de caracteristique nulle. On suppose que l'on se donne un sous-groupe parabolique standard de decomposition de Levi $P=MU$ ainsi qu'une representation irreductible temperee $\tau$ de $M$. Soit $\nu$ un element dans le dual de l'algebre de Lie de la composante deployee de $M$; on le choisit dans la chambre de Weyl positive. La representation induite $I_P^G(\tau_{\nu})$ est appelee module standard. Quand la representation $\tau$ est generique (pour un caractere non-degenere de $U$), i.e a un modele de Whittaker, le module standard $I_P^G(\tau_{\nu})$ est egalement generique.Casselman et Shahidi ont conjecture que l'unique sous-quotient generique apparaissait necessairement comme sous-representation dans le module standard $I_P^G(\tau_{\nu})$. Ceci a ete demontree dans le cas des groupes classiques $SO(2n+1), Sp(2n)$, et $SO(2n)$ quand $P$ est un sous-groupe parabolique maximal de $G$, par Hanzer en 2010.Dans notre travail, nous formulons et etudions ce probleme dans le contexte plus general d'un groupe connexe quasi-deploye tel que les composantes irreductibles de $\Sigma_{\sigma}$ sont de type $A,B,C$ ou $D$. Dans la deuxieme partie de cette these (en commun avec D.Prasad), nous prouvons d'abord qu'il n'existe pas de representation cuspidale du groupe quasi-deploye $\U_{2n}(F)$ qui soit distinguee par son sous-groupe $\Sp_{2n}(F)$ pour $F$ un corps local non-Archimedien. Nous prouvons ensuite le theoreme equivalent pour un corps global: il n'existe pas de representation cuspidale de $\U_{2n}(\A_k)$ qui ait une periode symplectique non nulle pour $k$ un corps de nombres ou corps de fonctions.
Orthogonal Frequency Division Multiplexing Directional Modulation Waveform Design for Integrated Sensing and Communication Systems

—Orthogonal frequency division multiplexing (OFDM) signals have been widely studied as a potential waveform used in integrated sensing and communication (ISAC) systems. High computational effort, however, is required to estimate the azimuth of the target and suppress the interference from the non-target directions. Moreover, along the non-target directions, the transmitted conﬁdential information can be easily intercepted by the eavesdroppers. In this paper, directional modulation (DM) technology combined with OFDM waveforms namely, OFDM-DM, is proposed for ISAC systems. From the sensing perspective, the interference from the non-target direction can be suppressed, and three-dimensional (3-D) radar images can be calculated without consuming extra computational resources. From a communication perspective, the OFDM-DM signals provide a secured physical-layer wireless transmission link and thus the conﬁdential information can be securely delivered to the target. The efﬁcacy of the proposed OFDM-DM ISAC waveforms is validated via numerical results for both sensing and communication functionalities by comparison with the traditional OFDM ISAC waveforms.
Heat Transfer Enhancement through Perforated Fin Made by Al-SiC-MMC and Optimization of Design Parameters using Taguchi DOE Method

: Aluminium silicon carbide metal matrix composites are employed in a wide range of applications, including aerospace, aviation, automobiles, turbine blades, and brake pads. Aluminum silicon carbide metal matrix composites can be made using a variety of manufacturing processes (Al-SiC MMC). Stir casting is the simplest, least expensive, and most widely used procedure among the many ways. By Stir Casting, Fin Specimens made with varied volume percentages of SiC (5, 10, and 15%) in Al and Al as a base matrix. The rectangular fin's cross-sectional area was 40 mm x 3 mm, and its length was 100 mm. Experiments were conducted across a rectangular fin with lateral circular holes of varied porosities of 0.028, 0.038, 0.050, and 0.064, as well as variable flow rates from 4-7 m/s in 1 m/s increments. The design optimization parameters and associated levels were evaluated by using Taguchi L16 experimental design method. The heat transfer of the Al-SiC nanocomposite was improved by increasing the volume percent ofSiC particles, according to the findings. For porosity 0.064 friction factor and pressure drop, a combination of 85 percent Al-15 percent SiC produced a high heat transfer coefficient and enhanced heat transfer rate as compared to standard aluminum. The optimal results were discovered for a fin composed of 85 percent Al-15 percent SiC, which compares favorably to conventional fin materials while being lighter and stronger than any of them. Investigating the fin's porosity, velocity, and composition yielded the best findings. The velocity, porosity, and composition have a greater influence on the heat transfer coefficient and Nusselt number, according to research.
Ready to SQI? Safety first! Towards a constant-time implementation of isogeny-based signature SQIsign

NIST has already published the first round of submissions for additional post-quantum signature schemes and the only isogeny-based candidate is SQIsign. It boasts the most compact key and signature sizes among all post-quantum signature schemes. However, its current implementation does not address side-channel resistance. This work is the first to identify a potential side-channel vulnerability in SQIsign. At certain steps within the signing procedure, it relies on Cornacchia’s algorithm to represent an integer as a sum of squares of two integers. This algorithm in turn uses a ‘half-GCD’ (half-greatest common divisor) sub-routine based on Euclid’s division algorithm which has often been exploited for side-channel attacks. We show that if the inputs of Cornacchia’s algorithm leak, then one can retrieve the signing key in polynomial time. Also, since there is no constant-time implementation for SQIsign, we propose two timing attack-resistant versions of Cornacchia’s algorithm. The first version uses a constant-time ‘half-GCD’ algorithm that runs a fixed number of times for a given upper bound based on the bit-size of the inputs. The second version is based on the two-dimensional lattice reduction algorithm. We show that randomizing the starting basis with an unimodular matrix would make the execution time independent of the input.
Virtual and augmented reality gamification of visuospatial neglect treatment: therapists’ user experience

Background Visuospatial neglect (VSN) is a cognitive disorder after stroke in which patients fail to consciously process and interact with contralesional stimuli. Visual Scanning Training (VST) is the recommended treatment in clinical guidelines. At the moment, several mixed reality versions of Visual Scanning Training (VST) are being developed. The aim of this study was to explore the opinions of end-users (i.e., therapists) on the use of Virtual Reality (VR) and Augmented Reality (AR) in VSN treatment. Methods Therapists played one VR and two AR Serious Games, and subsequently filled out a questionnaire on User Experience, Usability, and Implementation. Results Sixteen therapists (psychologists, occupational, speech, and physiotherapists) played the games, thirteen of them evaluated the games. Therapists saw great potential in all three games, yet there was room for improvement on the level of usability, especially for tailoring the games to the patient’s needs. Therapists’ opinions were comparable between VR and AR Serious Games. For implementation, therapists stressed the urgency of clear guidelines and instructions. Discussion Even though VR/AR technology is promising for VSN treatment, there is no one-size-fits-all applicability. It may thus be crucial to move towards a plethora of training environments rather than a single standardized mixed reality neglect treatment. Conclusion As therapists see the potential value of mixed reality, it remains important to investigate the efficacy of AR and VR training tools.
Revolutionizing fruit juice: exploring encapsulation techniques for bioactive compounds and their impact on nutrition, flavour and shelf life

Bioactive compounds in food and beverages, including fruit juices, are susceptible to degradation or oxidation during processing and storage. This vulnerability can lead to a reduction in nutritional value and overall quality of the products. The objective of this research is to explore the potential of encapsulation techniques in preserving and enhancing the nutritional value of fruit juices. The encapsulation of natural compounds, enzymes, and probiotics is seen as a promising approach to fortifying fruit juices, improving their preservation and processing of these encap‑ sulated natural compounds as additives in food packaging. The study involves a comprehensive review of various encapsulation techniques and materials used for encapsulating bioactive compounds. It also investigates the cur‑ rent applications of encapsulated natural products in the preservation of food and beverages. The encapsulation of bioactive compounds has shown the potential in improving the nutritional value and functional properties of fruit juice products and foods. It has also been found to enhance the preservation and processing of these products, contributing to their overall quality and safety. Encapsulation techniques offer a promising avenue for revolutionizing the fruit juice industry by enhancing the nutritional value and shelf life of products. They also present an opportunity for the development of more functional food products. Despite the promising results, more research is needed to fully understand the mechanisms of encapsulation, determine the optimal conditions for encapsulating different ingre‑ dients, and assess the effects of encapsulation on the quality and safety of fruit juices. Future studies should focus on these areas to further advance the application of encapsulation techniques in the food and beverage industry.
2018) Bandwidth enhancement of three-device Doherty power amplifier based

: This paper proposes a method for extending the bandwidth of a three-device Doherty power ampli ﬁ er (DPA) based on symmetric devices. λ / 4 transmission lines are inserted between each peaking ampli ﬁ er output and carrier ampli ﬁ er output to compensate load impedance of carrier ampli-ﬁ er. In order to achieve perfect load modulation, carrier ampli ﬁ er output circuit total electrical length is designed to 90 degrees, and the peak ampli ﬁ er output total electrical length is designed to 180 degrees. The proposed method is demonstrated by designing a three-device broadband DPA using three 10-W packaged GaN HEMT devices. Measurement results show that over 40% drain e ﬃ ciency is achieved at 9-dB back-o ﬀ power, over the frequency band of 1.45 – 2.35 GHz, accounting for 46% fractional bandwidth.
