Injection Harmonic Current Differential Protection Based on Control-Protection Synergy for Distribution Networks with IBDGs

The high penetration of inverter-based distributed generations (IBDGs) leads to traditional distribution networks’ complex and variable fault characteristics. Traditional passive detection protection methods can hardly meet the stability and reliability requirements. To solve this problem, an injection harmonic current differential protection (IHCDP) scheme based on the idea of control-protection synergy is proposed in this paper. By analyzing the circuit structure, control strategy, low-voltage-ride-through characteristics of IBDGs, and short-circuit currents provided by IBDGs, an injection-control strategy of characteristic harmonic currents (CHCs) based on the d-axis and q-axis is proposed. According to the change of short-circuit currents provided by the IBDG, the amplitude of CHCs is adaptively corrected to strengthen the fault characteristics and ensure that the distribution network harmonic injection protocols are always satisfied. An IHCDP criterion based on the distortion rate of the negative-sequence component of CHCs is proposed by analyzing the fault characteristics of the CHCs after injection. To effectively eliminate the dead-zone problem during symmetrical short-circuit faults, the proposed IHCDP utilizes the distortion rate of A-phase CHCs. The feasibility of the proposed protection scheme is demonstrated by the theoretical analysis and simulation results in this paper.
Can Dietary Patterns Impact Fertility Outcomes? A Systematic Review and Meta-Analysis

There are conflicting results on the effect of diet on fertility. This study aimed to assess the effect of different dietary patterns on fertility outcomes in populations who conceive spontaneously and those requiring assisted reproductive technology (ART). A systematic search and meta-analysis were performed for studies investigating dietary patterns or whole diets in reproductive aged women requiring ART or conceived naturally. Outcomes were live births, pregnancy rates and infertility rates. In amount of 15,396 studies were screened with 11 eligible studies. Ten different diet patterns were grouped broadly into categories: Mediterranean, Healthy or Unhealthy. For the Mediterranean diet, on excluding high risk-of-bias studies (n = 3), higher adherence was associated with improved live birth/pregnancy rates in ART [OR 1.91 (95% CI 1.14–3.19, I2 43%)] (n = 2). Adherence to various Healthy diets was associated with improved ART outcomes (ProFertility diet and Dutch Dietary Guidelines) and natural conception outcomes (Fertility diet). However, due to the variability in Healthy diets’ components, results were not pooled. Studies demonstrated preliminary evidence for the role of dietary patterns or whole diets in improving pregnancy and live birth rates. However, due to heterogeneity across the literature it is currently unclear which diet patterns are associated with improvements in fertility and ART outcomes.

Non-renewable input and waste stock: optimal transition towards circularity

Natural resource stocks are drastically shrinking and the contempo-rary debate on depletion of reserves highlights their crucial role over time. This paper deals with the management of exhaustible resources when recycling and extraction are employed, as well as the short-term eﬀects of the economic transition towards circularity on consumption and welfare. Mathematical modeling may support eﬀective plans for maximizing social welfare and protecting the environment. Concerning the production of a certain good, an optimal control model is studied to allocate labor between mining and recycling over a ﬁnite time horizon. A suit-able scrap value function allows for reducing waste and maintaining natural stock in the forthcoming future. Well-posedness of the problem is proved and some qualitative features of the optimal solution are stated.
Improving Consistency of EKF-based SLAM Algorithms by Using Accurate Linear Approximation

This paper presents a modified EKF-based SLAM algorithm to improve the consistency of the EKF-based SLAM algorithms. The proposed algorithm extracts the exact linear approximation of the measurements, which is considered as a variable, updates it using the new measurements, and finally transforms it back into the original state. The exact linear approximation is achieved by maintaining the point for linearization and updated along with the state. In this way, the structure of the variables being updated is more accurate, and the inconsistency of the EKF-based SLAM is greatly reduced, while at the same time, the computation and memory requirements do not increase too much. Simulation and experiment results demonstrate the advantages of the new algorithm.
The Level of Health Culture Related to Heart Disease Among Students of the Faculty of Artificial Intelligence at Al-Balqa Applied University

Increasing awareness of any disease, especially heart disease, is crucial to improve health culture in general. The lack of communication between the different departments of social and health institutions may hinder such increasing awareness due to the lack of enough research that highlights this problem. As health culture education related to heart diseases raises young people’s awareness, it improves their lives by developing their knowledge and changing their attitudes, habits, and behaviours towards the risk factors related to such diseases. Therefore, this research aimed to determine the level of health culture related to heart disease among students at Al-Balqa Applied University. The descriptive approach was used in its analytical and survey styles to achieve the research objective, and the research sample consisted of 221 male and female students. The results showed that the total score for the level of health culture related to heart disease among the students was average. In light of the results, the researcher presented several recommendations. The most important are holding health education and awareness seminars and workshops for university students in the field of heart disease and its prevention and activating the role of Al-Balqa Applied University in the continuous guidance and counselling of students in all disciplines and levels to increase the health culture of heart disease.
Modified Cooley-Tukey FFT method for Polynomial Multiplication in Lattice Cryptography

A new viewpoint on designing a finite-field multiplier architecture is suggested. The proposed architecture trades decrease in the number of clock cycles with not as much additional hardware area. The architecture presents high performance, succinct structure, reconfigurability and irrelevance on the choice of the Galois field. It can be applied to high security cryptographic applications such as lattice cryptography defined with Zp(x)/(x +1).
Hepatitis C Cirrhosis, Hepatitis B Superimposed Infection, and the Emergence of an Acute Portal Vein Thrombosis: A Case Report

Acute portal vein thrombosis (PVT) is a complication of liver cirrhosis. The presence of viral infections such as hepatitis B (HBV) and hepatitis C (HCV) can further increase cirrhotic patients’ risk of developing PVT, especially in the rare case when there is superinfection with both HBV and HCV. We present a patient with HCV cirrhosis whose clinical condition was decompensated secondary to the development of superimposed HBV infection, who developed acute PVT during hospitalization. This case offers a unique presentation of acute PVT that developed within several days of hospitalization for decompensated liver disease, as proven by the interval absence of portal venous flow on repeat imaging. Despite the workup on the initial presentation being negative for PVT, reconsideration of differentials after the change in our patient’s clinical status led to the diagnosis. Active HBV infection was likely the initial trigger for the patient’s cirrhosis decompensation and presentation; the subsequent coagulopathy and alteration in the portal blood flow triggered the development of an acute PVT. The risk for both prothrombotic and antithrombotic complications remains high in patients with cirrhosis, a risk that is vastly increased by the presence of superimposedinfections. The diagnosis of thrombotic complications such as PVT can be challenging, thus stressing the importance of repeat imaging in instances where clinical suspicion remains high despite negative imaging. Anticoagulation should be considered for cirrhotic patients with PVT on an individual basis for both prevention and treatment. Prompt diagnosis, early intervention, and close monitoring of patients with PVT are crucial for improving clinical outcomes. The goal of this report is to illustrate diagnostic challenges that accompany the diagnosis of acute PVT in cirrhosis, as well as discuss therapeutic options for optimal management of this condition.
Highly Sensitive Ethylene Sensors Based on Ultrafine Pd Nanoparticles-Decorated Porous ZnO Nanosheets and Their Application in Fruit Ripeness Detection

Ethylene is the most common ripening phytohormone in fruits, and excess ethylene can overripen the fruit. However, the in-field detection of ethylene is still limited. In this work, ultrafine Pd nanoparticles-decorated porous ZnO nanosheets (UPNP ZnO nanosheets) were conveniently synthesized through a facile solvent reduction method. The UPNP ZnO nanosheets were characterized using scanning electron microscopy, transmission electron microscopy, energy dispersive spectrum, X-ray diffraction and X-ray photoelectron spectroscopy. The ZnO nanosheets were uniformly coated with Pd nanoparticles. The size of the Pd nanoparticle was very small, with a diameter of approximately 2 nm. Due to the unique structure of the porous ZnO nanosheets and the excellent catalytic properties of the ultrafine Pd nanoparticles, the as-prepared samples showed very high sensing performance in ethylene detection. The lowest detection concentration was 10 ppb, which is the lowest detection limit to our knowledge. It has been proved that the decoration of ultrafine Pd nanoparticles can largely increase the relative percentage of chemisorbed oxygen and deficient oxygen, which are benefits for ethylene oxidation, and actually accelerate the process of the sensing reaction. Furthermore, the UPNP ZnO nanosheets can even be applied in fruit maturity detection. Using mangos as an example, our experiment revealed that the response of UPNP ZnO nanosheets to mangos at different maturity stages was quite different. This result suggests that our product has broad application prospects in monitoring fruit ripening stage.

Application of Nanoprecipitation Technique to Develop Poloxamer-407 Facilitated Solid Lipid Nanoparticles for the Controlled Delivery of Tacrolimus

Currently, the solid lipid nanoparticles (SLNs) are utilized as a novel approach for the controlled drug delivery system (CDDS). Tacrolimus (TCM), a lipophilic drug, can easily be encapsulated in the hydrophobic core of these SLNs using nanoprecipitation technique. The current aim was to develop the controlled release Poloxamer (PLX) facilitated TCM loaded SLNs (PLX/TCM-SLNs), followed by their physicochemical evaluations, including chemical compatibility, particle size, surface charge, surface morphology, nature of SLNs, loading efficiency (LE), entrapment efficiency (EE), in vitro drug release studies, release kinetic modeling, and statistical evaluation. Here we also evaluate physicochemical properties of TCM and investigate solubility profile for improvement and dissolution rate of PLX/TCM-SLNs. PLX was used in the process as a polymer due to its low toxicity and weak immunogenic properties. The prepared formulation was characterized by scanning electron microscopy (SEM) images, and Fourier transform infrared spectroscopy (FTIR) has confirmed the compatibility of the selected ingredients, whereas particle size analysis showed that prepared PLX/TCM-SLNs were of nanosized ( 120.6 ± 9 nm) having zeta potential of −21.3 Mv. On the other hand, SEM had revealed the smooth and uniform surface of the particle, while X-ray diffraction (XRD) confirmed the uniform surface as crystalline structure of TCM in PLX/TCM-SLNs masked. A satisfactory level of EE ( 94.5 ± 2.74 %) has also been noticed. Furthermore, in vitro drug release studies have explored the controlled release of drug during 8 hours, following zero order release kinetics and diffusion type of release mechanism. Outcomes of the studies have advocated the successful preparation of SLNs, as controlled release PLX/TCM-SLNs have been prepared efficiently.
An Opposed Piston Driving Pneumatic Stepper Motor for MR Intervention Robotics

Magnetic resonance (MR) safe robots offer many advantages to robot-assisted surgeries in the magnetic resonance imaging (MRI) environment. As one of the key components, the design of actuators that work in the MR environment is critical for MR safe robots. This article proposed a new piston motor powered by compressed air for MR safe robots, in which the working principle is investigated, and the dynamic model is analyzed. Linear motion is achieved by applying the lead screw transmission. Experiments demonstrate that the rotary motor has a maximum speed of 800 r/min and maximum output torque of 132 mN·m, and the linear motor has an output force of 50 N, both at a speed of 2 steps/s. The step response and error analysis are also conducted. MR tests show that there are no obvious image artifacts caused by the motor.
Oral Methadone versus Morphine IR for Patients with Cervical Cancer and Neuropathic Pain: A Prospective Randomised Controlled Trial

Objectives: In India, cervical cancer is the most common cancer among women and makes up for up to 29% of all registered cancer in females. Cancer-related pain is one of the major distressing symptoms for all cancer patients. Pain is characterised as somatic or neuropathic, and the total pain experience is often mixed. Conventional opioids are the backbone of analgesic treatment but are most often not sufficient in alleviating neuropathic pain, common in cervical cancer. Accumulating evidence of the advantage of methadone compared to conventional opioids, due to agonist action at both μ and q opioid receptors, N-methyl-D-aspartate (NMDA) antagonist activity and the ability to inhibit the reuptake of monoamines has been demonstrated. We hypothesised that, with these properties’, methadone might be a good option for the treatment of neuropathic pain in patients with cervical cancer. Material and Methods: Patients with cervical cancer stages ll-lll were enrolled in this randomized controlled trial. A comparison was made between methadone versus immediate release morphine (IR morphine), with increasing doses until pain was controlled. Inclusion-period was from October 3rd to December 31st 2020, and the total patient-study period was 12 weeks. Pain intensity was assessed according to the Numeric Rating Scale (NRS) and Douleur Neuropathique (DN4). The primary objective was to determine whether methadone was clinically superior versus noninferior to morphine as an analgesic for the treatment of cancer related neuropathic pain in women with cervical cancer. Results: A total of 85 women were included; five withdrew and six died during the study period, leaving 74 patients completing the study. All participants showed a reduction in mean values of NRS and DN4 from the time of inclusion and to the end of the study period, for IR morphine and methadone 8.4–2.7 and 8.6–1.5, respectively (P < 0.001). The DN4 score mean reduction for Morphine and Methadone were 6.12–1.37 and 6.05–0, respectively (P < 0.001). Side effects were more common in the group of patients receiving IR morphine compared to the patients treated with methadone. Conclusion: We found that Methadone had a superior analgesic effect with good overall tolerability compared with morphine as a first-line strong opioid for the management of cancer-related neuropathic pain.
Novel vs. modified platelet-rich plasma therapy for hair loss treatment: a systematic review and meta-analysis

Background: Platelet-rich plasma (PRP) therapy, is a stand-alone therapy or is used in combination with other treatments for the treatment of androgenic alopecia. The purpose of this meta-analysis was to compare the improvement in hair density seen, when PRP was used alone and when used as an adjunct. Methods: Conforming to systematic review and meta-analysis recommendations, we performed a meta-analysis of relevant articles in multiple databases, from inception till May 2022. Randomized clinical trials were included that evaluated the use of PRP alone or used PRP as an adjuvant with previously used therapies. Hair density data at the start of treatment and follow-up after 3 and 6 months was used for analysis. Results: A review of 255 articles included nine studies, for a cumulative data set of 230 individuals. In comparison to the placebo, stand-alone PRP therapy resulted in a significant increase in hair density (MD=25.39, P<0.00001.) PRP combination therapy also showed marked improvement in hair density compared to placebo (MD=34.38, P=0.002.) When comparing stand-alone PRP to combination therapy, MD=36.16, and MD=34.63 was observed for the two groups, respectively. Conclusions: The results of this meta-analysis reaffirm previous studies that suggest the role of PRP in improving hair density in AGA; however, the results cannot justify the use of PRP-combined therapy. Stand-alone PRP therapy should be considered in the management protocols for both men and women, whereas more studies and may be, different combination therapies are required before combined therapy can be included in the management guidelines for AGA.
A Case of Critical Japanese Spotted Fever in Zhejiang, China

Background Japanese spotted fever (JSF) is a rare disease, caused by Rickettsia japonica; no case has been reported in Zhejiang Province, China. Case Presentation An elderly woman presented to the hospital with abdominal pain and fever. Her condition rapidly worsened with severe complications, such as multiple organ failure and central nervous system damage. The presence of R. japonica was quickly detected by metagenomic next-generation sequencing. On the basis of combined clinical manifestations and laboratory results, critical JSF was diagnosed and treated with doxycycline. The patient showed good prognosis. Typical symptoms (eschar and rash) were not observed in the early stage, consequently increasing the difficulty of clinical diagnosis. Conclusion The delay of treatment caused by non-specific symptoms is an important factor affecting the progression of JSF. As an emerging pathogen detection method, mNGS has been successfully applied for disease diagnosis and treatment, and can be an important complement for the diagnosis of this disease.
Using ECG Authentication for Biometrics in Smart Cities

All the biometric systems are based on some important features of these modalities which are mainly known for their uniqueness in one way or the other. However, the automatic attendance system using heart biometrics is focused as it is internally unique and focused on internal flexibility of the heart. Heart biometrics include different authentication modalities such as ECG, SCG, PCG and so on. It is primarily focused on authentication using ECG signals which uses algorithms or techniques such as SVM (support vector machine) for authentication purposes and dynamic time warping for signal matching. Algorithms used have shown high accuracy results and the challenges faced were considerable and effectively managed to improve for further advancements.
COMPARISON THEOREMS IN FINSLER GEOMETRY WITH WEIGHTED CURVATURE BOUNDS AND RELATED RESULTS

We first extend the notions of weighted curvatures, includ- ing the weighted flag curvature and the weighted Ricci curvature, for a Finsler manifold with given volume form. Then we establish some basic comparison theorems for Finsler manifolds with various weighted curva- ture bounds. As applications, we obtain some McKean type theorems for the first eigenvalue of Finsler manifolds, some results on weighted curva- ture and fundamental group for Finsler manifolds, as well as an estimation of Gromov simplicial norms for reversible Finsler manifolds.
Adenylosuccinic Acid: An Orphan Drug with Untapped Potential

Adenylosuccinic acid (ASA) is an orphan drug that was once investigated for clinical application in Duchenne muscular dystrophy (DMD). Endogenous ASA participates in purine recycling and energy homeostasis but might also be crucial for averting inflammation and other forms of cellular stress during intense energy demand and maintaining tissue biomass and glucose disposal. This article documents the known biological functions of ASA and explores its potential application for the treatment of neuromuscular and other chronic diseases.
