Published: November 2023

The galls of cynipid species (Hymenoptera: Cynipidae) have been used since ancient times as an important source of bioactive compounds. Many researchers have evaluated the medicinal potential of some cynipid galls and found that these galls have numerous ethnomedical uses. The aim of this study was to determine the total bioactive (phenolic, flavonoid and tannin) compound amounts of gall extracts, to reveal the phenolic compound contents by HPLC method and to set ground for future pharmaceutical studies. The galls of cynipid wasps (totally 24 taxa) on host plants were collected from the Eastern Black Sea Region of Türkiye. Acetone, ethanol, methanol, and water extracts of these galls were prepared for quantity analysis and HPLC. The phenolic compound amounts (phenolic, flavonoid and tannin) of the cynipid gall extracts were determined, and their phenolic compound contents were also revealed. Some phenolic compounds in ethanol gall extracts were analyzed using HPLC, and some of these compounds were detected for the first time in the cynipid galls. 2,5-dihydroxybenzoic acid, caffeic acid, epicatechin, and ellagic acid are the most abundant in the ethanolic gall extracts. Total phenolic, flavonoid and tannin amounts of the cynipid gall extracts showed high variation. All these studies on quantification and characterization of phenolic compound are the first detailed studies on these taxa of cynipid galls and show that these cynipid galls might pharmaceutically be an important source for human and animal health.
Economic value of virtual water with the approach of maximizing the productivity of irrigation water
Authors: Du Linyuan
Published: November 2023

The increasing use of water and the decrease in average rainfall along with climate change have caused the reduction of water resources in arid and semi-arid regions. In addition, despite the consumption of more than half of these resources in the agricultural sector, a rate between 0 and 15% of the price of the products has always been received from the farmers. Considering the concept of virtual water and the water content of products in the form of green water, blue water and gray water, the present research has calculated the economic value of virtual water of agricultural products with the approach of maximizing water use efficiency. The investigated sample includes eight cities (counties) of Sanmenxia, Jiaozuo, Nanyang, Shangqiu, Puyang, Luohe, Luoyang and Kaifeng and six agricultural products (wheat, barley, potato, rapeseed, tomato and corn). A fuzzy dynamic programming model has been used to evaluate the objective function. The results showed that the maximum and minimum economic value of water content (sum of surface and groundwater) of the products were estimated for Kaifeng and Shangqiu regions equal to 1.16 and 0.86 Yuan/m3, respectively.

Authors: Mahecha-Naranjo Gina , Álvarez-Alucema Leandro Efrain , Campo-Torregrosa Yelis , Caballero-Olivares Tirza , López-Sepúlveda Rubén
Published: November 2023

Introduction: Teaching requires dedication, time, and mental work due to the diversity of tasks that must be carried out, which can generate burnout (psychological exhaustion). However, reviews of the characteristics of burnout in Latin American university professors still need to be discovered. Objective: To characterize psychological exhaustion in university professors in Latin America. Method: A bibliographic review of original studies was conducted from different sources in Spanish, English, and Portuguese with the keywords work stress, burnout, psychological exhaustion, teaching, and university professors. The frequencies of the characteristics of the dimensions of psychological exhaustion were described. Results: Eleven investigations showed that depersonalization mainly manifests burnout (up to 90%). Emotional exhaustion and low personal fulfillment reached up to 82%. Conclusions: Burnout among university professors manifests mainly with depersonalization. New systematic reviews should summarize the variables associated with psychological exhaustion in Latin American university professors.

Drug Discovery Efforts to Identify Novel Treatments for Neglected
Tropical Diseases - Cysteine Protease Inhibitors
Authors: Giroud Maude , Kuhn Bernd , Haap Wolfgang
Published: November 2023

Background:

Neglected tropical diseases are a severe burden for mankind, affecting
an increasing number of people around the globe. Many of those diseases are
caused by protozoan parasites in which cysteine proteases play a key role in the parasite’s
pathogenesis.

Objective:

In this review article, we summarize the drug discovery efforts of the research
community from 2017 - 2022 with a special focus on the optimization of small
molecule cysteine protease inhibitors in terms of selectivity profiles or drug-like properties
as well as in vivo studies. The cysteine proteases evaluated by this methodology include
Cathepsin B1 from Schistosoma mansoni, papain, cruzain, falcipain, and rhodesain.

Methods:

Exhaustive literature searches were performed using the keywords “Cysteine
Proteases” and “Neglected Tropical Diseases” including the years 2017 - 2022. Overall,
approximately 3’000 scientific papers were retrieved, which were filtered using specific
keywords enabling the focus on drug discovery efforts.

Results and Conclusion:

Potent and selective cysteine protease inhibitors to treat neglected
tropical diseases were identified, which progressed to pharmacokinetic and in
vivo efficacy studies. As far as the authors are aware of, none of those inhibitors reached
the stage of active clinical development. Either the inhibitor’s potency or pharmacokinetic
properties or safety profile or a combination thereof prevented further development of
the compounds. More efforts with particular emphasis on optimizing pharmacokinetic
and safety properties are needed, potentially by collaborations of academic and industrial
research groups with complementary expertise. Furthermore, new warheads reacting
with the catalytic cysteine should be exploited to advance the research field in order
to make a meaningful impact on society.

Published: November 2023

Resistance to therapy and the toxicity of normal tissue are the major problems
for efficacy associated with chemotherapy and radiotherapy. Drug resistance is responsible
for most cases of mortality associated with cancer. Furthermore, their side effects
can decrease the quality of life for surviving patients. An enhancement in the tumor response
to therapy and alleviation of toxic effects remain unsolved challenges. One of the
interesting topics is the administration of agents with low toxicity to protect normal tissues
and/or sensitize cancers to chemo/radiotherapy. Melatonin is a natural body hormone
that is known as a multitasking molecule. Although it has antioxidant properties, a
large number of experiments have uncovered interesting effects of melatonin that can increase
the therapeutic efficacy of chemo/radiation therapy. Melatonin can enhance anticancer
therapy efficacy through various mechanisms, cells such as the immune system,
and modulation of cell cycle and death pathways, tumor suppressor genes, and also
through suppression of some drug resistance mediators. However, melatonin may protect
normal tissues through the suppression of inflammation, fibrosis, and massive oxidative
stress in normal cells and tissues. In this review, we will discuss the distinct effects
of melatonin on both tumors and normal tissues. We review how melatonin may enhance
radio/chemosensitivity of tumors while protecting normal tissues such as the lung,
heart, gastrointestinal system, reproductive system, brain, liver, and kidney.
Deacetylation of Histones and Non-histone Proteins in Inflammatory
Diseases and Cancer Therapeutic Potential of Histone Deacetylase Inhibitors
Authors: Man Ezgi , Evran Serap
Published: November 2023

abstract:

Epigenetic changes play an important role in the pathophysiology of autoimmune diseases
such as allergic asthma, multiple sclerosis, lung diseases, diabetes, cystic fibrosis, atherosclerosis,
rheumatoid arthritis, and COVID-19. There are three main classes of epigenetic alterations: posttranslational
modifications of histone proteins, control by non-coding RNA and DNA methylation.
Since histone modifications can directly affect chromatin structure and accessibility, they can regulate
gene expression levels. Abnormal expression and activity of histone deacetylases (HDACs) have been
reported in immune mediated diseases. Increased acetylated levels of lysine residues have been suggested
to be related to the overexpression of inflammatory genes. This review focuses on the effect of
HDAC modifications on histone and non–histone proteins in autoimmune diseases. Furthermore, we
discuss the potential therapeutic effect of HDAC inhibitors (HDACi) used in these diseases.

Published: November 2023

Objective::

With the rapid development in computed tomography (CT), the establishment of artificial intelligence (AI) technology and improved awareness of
health in folks in the decades, it becomes easier to detect and predict pulmonary nodules with high accuracy. The accurate identification of benign
and malignant pulmonary nodules has been challenging for radiologists and clinicians. Therefore, this study applied the unenhanced CT imagesbased
radiomics to identify the benign or malignant pulmonary nodules.

Methods::

One hundred and four cases of pulmonary nodules confirmed by clinicopathology were analyzed retrospectively, including 79 cases of malignant
nodules and 25 cases of benign nodules. They were randomly divided into a training group (n = 74 cases) and test group (n = 30 cases) according
to the ratio of 7:3. Using ITK-SNAP software to manually mark the region of interest (ROI), and using AK software (Analysis kit, Version 3.0.0.R,
GE Healthcare, America) to extract image radiomics features, a total of 1316 radiomics features were extracted. Then, the
minimum–redundancy–maximum–relevance (mRMR) algorithms were used to preliminarily reduce the dimension, and retain the 30 most
meaningful features, and then the least absolute shrinkage and selection operator (LASSO) algorithm was used to select the optimal subset of
features, so as to establish the final model. The performance of the model was evaluated by using the receiver operating characteristic (ROC)
curve, area under the ROC curve (AUC), accuracy, sensitivity and specificity. Calibration refers to the agreement between observed endpoints and
predictions, and the clinical benefit of the model to patients was evaluated by decision curve analysis (DCA).

Results::

The accuracy, sensitivity, and specificity of the training and testing groups were 81.0%, 77.7%, 82.1% and 76.6%, 85.7%, 73.9%, respectively, and
the corresponding AUCs were of 0.83 in both groups.

Conclusion::

CT image-based radiomics could differentiate benign from malignant pulmonary nodules, which might provide a new method for clinicians to
detect benign and malignant pulmonary nodules.
Multifunctional Drug Delivery System: Nanosponges
Authors: Barik Piyali , Bhaisal Pooja Rani , Singh Sonia
Published: November 2023

In recent years, nanotechnology has been the focus of study for the cure of different diseases, among which nanosponge delivery system is one of a kind. Nano sponges are tiny, highly porous,
three-dimensional nanostructures with a size range of 250nm-1µm in an amorphous or crystalline
structure. Nanosponges usually act as an excipient or carrier of a drug in the different delivery systems.
The type of polymers and cross-linkers, along with their concentration ratio, causes variation in nanosponges's dimension and encapsulation efficiency. Nanosponges have gained prominence in recent
times due to their distinct ability to encapsulate both hydrophilic and lipophilic drugs within their internal cavity, thereby improving the solubility of drugs that have low water solubility. Virus-like size
helps the nanosponges to circulate within the body without getting eliminated by the immune system
until they stick to the targeted part of the body, which makes it the perfect candidate for a targeted drug
delivery system and controlled delivery system as well because of its slow drug release property for a
more extended period. Cyclodextrin-based nanosponges are the best choice for anticancer drug delivery as their small virus-like diameter helps them in passive targeting by enhancing the enhanced permeability and retention effect, allowing the anticancer drug to stay inside the tumour cell to show more
significant therapeutic action on cancer, while for active targeting to the cancerous cell, nanosponges
are attached with a ligand on it for receptor binding purpose. It can be used for drug delivery in many
major diseases like brain-related diseases, diabetes, cancer, fungal, hypertension, etc., in different dosage forms, like oral, topical, hydrogel, parenteral, etc.
Spirulina: A Living Library of Anticancer Phytochemicals
Authors: Oluwasegun Samson Awotunde , Olu Richard Omogbadegun , Joseph Yusuf Mugambwa
Published: November 2023

Cancer is a group of diseases involving abnormal cell growth with the
potential to invade or spread to other parts of the body. It is one of the major causes of
human death, especially in developing countries. Alternative cancer treatments using
medicinal plants are exploited because plants produce phytochemical compounds,
which are secondary metabolites used for natural defence but could also be useful in
inhibiting cancer growth. Medicinal plants also have limited side effects and toxicity as
compared to conventional chemotherapy and irradiation treatments. Hence there is a
need to develop novel drugs from other sources like plants, fungi, and algae. Spirulina
is a blue-green alga with three species: Spirulina platensis, Spirulina fusiformis, and
Spirulina maxima. Spirulina platensis and Spirulina maxima are consumable by
humans in the form of dietary supplements, as they are enriched with important
nutrients and a library of phytochemicals that can improve immunity and levels of
blood lipids, lower blood sugar and blood pressure, and prevent oxidation. These
activities of Spirulina phytochemicals make them a good candidate for anticancer
therapy. Therefore, this chapter describes the botanical classification, phytochemical
composition, and anticancer characteristics of Spirulina and with a specific focus on
Spirulina platensis.

II-VI Semiconductor-based Thin-Film Transistor Sensor for Room Temperature Hydrogen Detection From Idea to Product Development
Authors: Ghosh Sukanya , Rajan Lintu
Published: November 2023

Implementing gas sensors incorporating nanoelectronic devices to detect
pollution and improve the safety control of industrial, medical, and domestic sectors
has opened up a novel world with immense interest. As a promising renewable energy
carrier and a potential replacement for fossil fuels, there is the paramount importance
of hydrogen gas storage at extensive facilities worldwide. The sustainable production
of hydrogen is increasing owing to its enormous energy per mass of any fuel.
Nevertheless, due to its extreme flammability, simple and highly accurate sensors with
promising sensing materials are required to detect the slightest traces of timely leak
detection for developing a hydrogen economy. Various hydrogen detectors already
exist, but expensive cost, large size, sluggish response, and high temperature limit their
potential for widespread applications. The integral objective of the present chapter is to
focus on a systematic investigation of Pd-Ti/ZnO Schottky TFT-based room
temperature hydrogen sensors excluding any heating element. With high chemical and
thermal stability, ZnO is a promising candidate for sensors in a hazardous atmosphere.
The developed sensor exhibited room temperature detection with a maximum response
of 33.8% to 4500 ppm H2
in dry air. The selectivity analysis toward H2
in the presence
of other reducing and oxidizing gas species has also been investigated to ensure the
real-time applicability of the sensor. Reliable operation of the sensor in a wide range of
500 ppm to 4500 ppm H2
has been confirmed from the linear behavior of the sensor.
The hydrogen sensing mechanism of the proposed sensor in terms of Schottky barrier
height reduction at the interface of Pd-Ti/ZnO has also been detailed in this chapter.
Room temperature detection of the hydrogen sensor presented here competes favorably
with the existing studies. This study can be extended in exploring new routes to realize
hydrogen sensing applications at room temperature for commercialization with precise
control over film thickness and target gas concentrations.

Currently, the Indo-Pacific region is one of the regions that has become an important concept in international relations, especially among ASEAN countries. This happens because there is an awareness that this area is strategic in various aspects and has a positive effect on countries in the region. However, the region faces several threats, including a rivalry between two major powers, the United States and China, and the presence of territorial sovereignty claims in the region. As a result, there is a need for increased awareness and regional countries' efforts to protect the region's stability from existing influences and threats. One form of awareness of the importance of maintaining the Indo-Pacific region can be seen in the ASEAN Outlook on the Indo-Pacific (AOIP). AOIP is initiated by one of the countries in the region, namely, Indonesia, where it becomes a means of Indonesian defence diplomacy to achieve national and regional interests. This article explains how Indonesia conducts its defence diplomacy in AOIP. This article uses descriptive methods by explaining and providing an overview of existing phenomena. Based on the process of collecting data from books, journals, and related official websites that can help explain and analyse this topic, the results of this analysis prove that AOIP becomes a form of Indonesian defence diplomacy because Indonesia sees various threats present in the region that can endanger its sovereignty and even the stability of the Indo-Pacific region. Thus, in its implementation, Indonesia conducts diplomacy through cooperation with countries in the region. Keywords: AOIP, Defense diplomacy, Indonesia, ASEAN, national interest

Kobieta w samorządzie, czyli o łączeniu ról społecznych. Postacie liderek angażujących się w działalność samorządową, które odgrywają lub odgrywały ważne role w życiu lokalnych/regionalnych wspólnot samorządowych
Authors: Sobieszczańska Aleksandra
Published: November 2023

Kobieta z początku XXI wieku jest już kimś zupełnie innym niż sto lat wcześniej: ma inne zajęcia, ambicje, inny status społeczny i stawiane są jej inne wymagania. Relacje międzyludzkie oraz rzeczywistość obyczajowa również różnią się od tych, w których funkcjonować miała kobieta jeszcze przed stoma laty. Czynnikami które odgrywały istotną rolę i które decydowały o miejscu kobiet w społeczeństwie, poza płcią, były wiek i pozycją społeczna. Obowiązujące uregulowania prawne, sposób postrzegania przez społeczeństwo, stosowane wzorce zachowań czy zakres wolności osobistej różniły się w zależności od tego, czy kobieta była mężatką, wdową, panną. W ujęciu antropologicznym należy zauważyć, iż każda epoka historyczna wypracowała swoiste wzorce kulturowe, ale dopiero powstanie nowoczesnych społeczeństw zaowocowało znaczącymi zmianami jakościowymi.

Understanding Loneliness in Younger People: Review of the Opportunities and Challenges for Loneliness Interventions
Authors: Shah Hurmat Ali , Househ Mowafa
Published: November 2023

Loneliness affects the quality of life of people all around the world. Loneliness is also shown to be directly associated with mental health issues and is often the cause of mental health problems. It is also shown to increase the risk of heart diseases and other physical illnesses. Loneliness is studied both from the social and medical sciences perspectives. There are also interventions on the basis of health informatics, information and communication technologies (ICTs), social media, and other technological solutions. In the literature, loneliness is studied from various angles and perspectives ranging from biological to socioeconomical and through anthropological understandings of technology. From the ICT and technological sides, there are multiple reviews studying the effectiveness of intervention strategies and solutions. However, there is a lack of a comprehensive review on loneliness that engulfs the psychological, social, and technological studies of loneliness. From the perspective of loneliness informatics (ie, the application of health informatics practices and tools), it is important to understand the psychological and biological basis of loneliness. When it comes to technological interventions to fight off loneliness, the majority of interventions focus on older people. While loneliness is highest among older people, theoretical and demographical studies of loneliness give a U-shaped distribution age-wise to loneliness; that is, younger people and older people are the demographics most affected by loneliness. But the strategies and interventions designed for older people cannot be directly applied to younger people. We present the dynamics of loneliness in younger people and also provide an overview of the technological interventions for loneliness in younger people. This paper presents an approach wherein the studies carried out from the perspectives of digital health and informatics are discussed in detail. A comprehensive overview of the understanding of loneliness and the study of the overall field of tools and strategies of loneliness informatics was carried out. The need to study loneliness in younger people is addressed and particular digital solutions and interventions developed for younger people are presented. This paper can be used to overcome the challenges of technological gaps in the studies and strategies developed for loneliness. The findings of this study show that the majority of interventions and reviews are focused on older people, with ICT-based and social media–based interventions showing promise for countering the effects of loneliness. There are new technologies, such as conversational agents and robots, which are tailored to the particular needs of younger people. This literature review suggests that the digital solutions developed to overcome loneliness can benefit people, and younger people in particular, more if they are made interactive in order to retain users.
A comparative study of Macbeth, adapted as Maqbool by Vishal Bharadwaj
Authors: Ray Neha Kumari
Published: November 2023

William Shakespeare's theatrical works have long been a fertile ground for reinterpretation and transformation. Within his plays, he explored fundamental themes such as love, marriage, family dynamics, issues of race and class, humour, betrayal, malevolence, vengeance, murder, and mortality. Through his masterful storytelling, Shakespeare crafted enduring characters, spanning from common criminals to noble monarchs, who have transcended time to become enduring archetypes in modern drama, while still retaining their relatable human essence. These timeless themes and iconic characters provide filmmakers with a rich reservoir of raw material to create visually captivating cinematic experiences. Renowned director Vishal Bhardwaj garnered substantial critical acclaim for his trilogy, with "Maqbool" drawing inspiration from "Macbeth," "Omkara" from "Othello," and "Haider" adapted from Shakespeare's "Hamlet." Nevertheless, Bhardwaj exercised creative liberties in moulding these narratives to suit his cinematic vision. This article embarks on an exploration of the comparative analysis between Vishal Bhardwaj's "Maqbool" and Shakespeare's "Macbeth." The discussion commences with a succinct overview of comparative literature, progressing to a detailed examination of the opening scenes, the art of characterization, the diverse dramatic techniques employed, the setting, and the denouement. Moreover, it delves into the points of convergence and divergence between the adaptation ("Maqbool") and the original source text ("Macbeth").

Wood can be used for fuel by direct burning, or as a raw material for other fuels; however, it is necessary to evaluate the energy properties to ensure the optimal use of this material. The most relevant characteristics to be analyzed are the higher heating value, volatile material content, fixed carbon content, and ash content. Along with the traditional methods, there are also non-destructive evaluations that are optimized for speed and reliability. Among these methods, visible spectroscopy and near-infrared spectroscopy have been proven to be robust for the prediction of several wood properties. The aim of this study was to evaluate the potential of visible spectroscopy and near-infrared spectroscopy for species discrimination and prediction of higher heating value, volatile material content, fixed carbon content, and ash content for Eucalyptus saligna, Eucalyptus dunnii, and Eucalyptus benthamii woods. For this purpose, multivariate principal component analysis and partial least squares regression were applied to the collected spectra. The principal component analysis satisfactorily discriminated the three species, explaining 99% of the variance of the visible spectroscopy spectra and 73% of that of the near-infrared spectra. The estimation of energetic properties through partial least squares regression was satisfactory for both visible spectroscopy and near-infrared spectroscopies, which presented calibration R² values close to 1 and low errors for all properties studied.

The purpose of the article is a historical and legal analysis of the features of the youth policy formation during the transition of domestic liberalism from the level of theoretical developments. The authors consider the concepts of transformation of the socio-political system of Russia at the stage of political and organizational constitution of liberal political forces of the early 20-th century. Youth and politics is a complex and multifaceted subject that uses historical, political and sociological analysis, comparison and syn-thesis. For a more complete study, the authors use an integrated approach that combines various methods and principles. Based on archival materials of the collegial governing bodies of the People's Freedom Party, con-gresses, conferences, the Central Committee, as well as sparsely distributed materials of the Moscow and St. Petersburg committees of the party, an analysis of inter-action with youth organizations is presented. The authors trace the evolution of ideas about ways to involve young people in the political environment. As a result, the authors conclude that not everyone reacted unambiguously regarding the expediency of student youth participation in the party life of cadets. It is shown that the basic trend of the youth policy of the Russian liberals remained the refusal to involve students in the process of political struggle. The consequence of this is the loss of popularity among Russian liberals among students, as well as the predominance of the influence of radical political forces of Russia on students.

The purpose of the article is to study the activities of Orel trade unions on the development of physical culture and mass work and sports in 1923-1991. Statistical and reference materials, documents of the Orel State Archive, sports veterans’ memories are used as the main sources. In the course of the study, the system analysis, the retrospective method, the method of historicism are used. The article analyzes the prerequisites for conducting physical culture and mass work and the development of sports by trade unions; the historical stages of this work are identified. The fact that the trade unions of the country looked for new forms of relations with the working class after the October Revolution is established. One of them was physical culture and mass work and the development of sports. Achieving these goals required a significant amount of organizational and financial resources. The activity of the sports society "Trud" was indicative in Orel region. It was established in January 1958 on the basis of voluntary sports societies of trade unions and club work carried out since 1923. As a conclusion, the authors point out that the formation and activity of the sports society "Trud" largely reflects the history of the trade union movement in Russia for the development of physical culture and mass work and sports in the Soviet period.

The purpose of the article is to study the activities of the Orel regional branch of the All-Russian society for the preservation of historical and cultural monuments (VOOPIK) in the context of socio-political, ideological, economic and cultural transformations characteristic of the period of "perestroika". On the basis of the analysis of the changes that took place in the system of state-public relations after the proclamation of M.S. Gorbachev in 1985, the course of radical reform of the Soviet system the results of the transformations are structured. Since the beginning of the 1970s, the Soviet Union has been actively reforming monument protection bodies. Development of the system of state-public relations in the field of cultural heritage preservation, including the role of public associations in the protection of monuments. VOOPIK fits firmly into this sys-tem. This circumstance, on the one hand, gives the Society quite broad powers on issues of heritage protection. On the other hand, it causes its dependence on the state (as well as the dependence of regional branches on the Central Council of the Society). This is most clearly seen in matters of material and financial support. In the first half of the 1980s, VOOPIK faced serious financial difficulties after the cancellation of contributions from collective members in 1983. Having lost a significant part of income, from 1983-1984. Almost all branches of the Society were forced to abandon some projects and a number of new initiatives. The Orel regional branch of the VOOPIK was no exception. As a result, the authors conclude that by the beginning of the period of "perestroika", it came weakened financially. In addition, personnel changes had a negative impact on the activities of the department and the mood in the team.
Real-Time Low Voltage Ride Through Capability Improvement of PMSG-Wind Turbine Based on Robust Fractional Order Sliding Mode Control

In this article, a fractional-order sliding mode control (FOSMC) method
is presented for a wind energy conversion system (WECS) with
variable-speed direct-drive permanent magnet synchronous generator
(PMSG) under both normal and fault conditions. Under normal operation of
the system, the machine side converter (MSC) is employed to meet maximum
power point tracking (MPPT) requirements of the wind turbine and the
grid side converter (GSC) controls the DC-link voltage and the injected
reactive. Under fault condition, to meet grid code obligations, such as
low voltage ride through (LVRT), the MSC adjusts the DC-link voltage
instead of the GSC. Meanwhile, the active and reactive powers are
controlled by the GSC. Moreover, the suggested control method is
compared to the conventional control system. The results depicted that
the proposed control approach has better faster dynamic response and
robustness under both balanced and unbalanced condition. In addition,
improving LVRT capability and injecting reactive power, the suggested
control method results in smaller spikes in the injected current and DC
link voltage. For the sake of further validation, simulations are run in
offline MATLAB/Simulink simulation. Then, the results have been
validated via experimental real-time implementation.

NOAA’s Daily Optimum Interpolation Sea Surface Temperature (DOISST)
indicates that globally averaged sea surface temperature (SST) broke
record in March 2023 and set new record highs in April, July, and August
2023. This has raised intense media interest and public concern about
causes and connections to climate change. Our analysis indicates that
the record high SSTs qualified as marine heatwaves (MHWs) and even
super-MHWs as defined in this study, and are attributed to three
factors: (i) a linear trend, (ii) a shift to the warm phase of the
multi-decadal Pacific-Atlantic-Arctic Oscillation(PAO) pattern which
is identified in this study, and (iii) the transition from the
triple-dip succession of La Niña events to the 2023 El Niño event.

One-Sentence Summary

The extreme warm SSTs in 2023 resulted from linear warming trends, a
pattern of low-frequency oscillation, and the El Niño event.
