Utilizing vocalizations to gain insight into the affective states of non-human mammals
Authors: Whitham Jessica C. , Miller Lance J.
Published: February 2024

This review discusses how welfare scientists can examine vocalizations to gain insight into the affective states of individual animals. In recent years, researchers working in professionally managed settings have recognized the value of monitoring the types, rates, and acoustic structures of calls, which may reflect various aspects of welfare. Fortunately, recent technological advances in the field of bioacoustics allow for vocal activity to be recorded with microphones, hydrophones, and animal-attached devices (e.g., collars), as well as automated call recognition. We consider how vocal behavior can be used as an indicator of affective state, with particular interest in the valence of emotions. While most studies have investigated vocal activity produced in negative contexts (e.g., experiencing pain, social isolation, environmental disturbances), we highlight vocalizations that express positive affective states. For instance, some species produce vocalizations while foraging, playing, engaging in grooming, or interacting affiliatively with conspecifics. This review provides an overview of the evidence that exists for the construct validity of vocal indicators of affective state in non-human mammals. Furthermore, we discuss non-invasive methods that can be utilized to investigate vocal behavior, as well as potential limitations to this line of research. In the future, welfare scientists should attempt to identify reliable, valid species-specific calls that reflect emotional valence, which may be possible by adopting a dimensional approach. The dimensional approach considers both arousal and valence by comparing vocalizations emitted in negative and positive contexts. Ultimately, acoustic activity can be tracked continuously to detect shifts in welfare status or to evaluate the impact of animal transfers, introductions, and changes to the husbandry routine or environment. We encourage welfare scientists to expand their welfare monitoring toolkits by combining vocal activity with other behavioral measures and physiological biomarkers.

Based on the evidence of a significant communication and connection pathway between the bone and immune systems, a new science has emerged: osteoimmunology. Indeed, the immune system has a considerable impact on bone health and diseases, as well as on bone formation during grafts and its stability over time. Chronic inflammation induces the excessive production of oxidants. An imbalance between the levels of oxidants and antioxidants is called oxidative stress. This physio-pathological state causes both molecular and cellular damage, which leads to DNA alterations, genetic mutations and cell apoptosis, and thus, impaired immunity followed by delayed or compromised wound healing. Oxidative stress levels experienced by the body affect bone regeneration and maintenance around teeth and dental implants. As the immune system and bone remodeling are interconnected, bone loss is a consequence of immune dysregulation. Therefore, oral tissue deficiencies such as periodontitis and peri-implantitis should be regarded as immune diseases. Bone management strategies should include both biological and surgical solutions. These protocols tend to improve immunity through antioxidant production to enhance bone formation and prevent bone loss. This narrative review aims to highlight the relationship between inflammation, oxidation, immunity and bone health in the oral cavity. It intends to help clinicians to detect high-risk situations in oral surgery and to propose biological and clinical solutions that will enhance patients’ immune responses and surgical treatment outcomes.

Published: February 2024

(1) Background: Nonalcoholic Steatohepatitis/Nonalcoholic Fatty Liver Disease (NASH/NAFLD) is the most recurrent chronic liver disease. NASH could present with a cholestatic (C) or hepatic (H) pattern of damage. Recently, we observed that increased Epithelial Cell Adhesion Molecule (EpCAM) expression was the main immunohistochemical feature to distinguish C from H pattern in NASH. (2) Methods: In the present study, we used digital pathology to compare the quantitative results of digital image analysis by QuPath software (Q-results), with the semi-quantitative results of observer assessment (S-results) for cytokeratin 7 and 19, (CK7, CK19) as well as EpCAM expression. Patients were classified into H or C group on the basis of the ratio between alanine transaminase (ALT) and alkaline phosphatase (ALP) values, using the “R-ratio formula”. (3) Results: Q- and S-results showed a significant correlation for all markers (p < 0.05). Q-EpCAM expression was significantly higher in the C group than in the H group (p < 0.05). Importantly ALP, an indicator of hepatobiliary disorder, was the only biochemical parameter significantly correlated with Q-EpCAM. Instead, Q-CK7, but not Q-CK19, correlated only with γGlutamyl-Transferase (γGT). Of note, Stage 4 fibrosis correlated with Q-EpCAM, Q-CK19, and ALP but not with γGT or ALT. Conclusions: Image analysis confirms the relation between cholestatic-like pattern, associated with a worse prognosis, with increased ALP values, EpCAM positive biliary metaplasia, and advanced fibrosis. These preliminary data could be useful for the implementation of AI algorithms for the assessment of cholestatic NASH.
Multifunctional Exosomes Derived from M2 Macrophages with Enhanced Odontogenesis, Neurogenesis and Angiogenesis for Regenerative Endodontic Therapy: An In Vitro and In Vivo Investigation
Authors: Wang Yujie , Mao Jing , Wang Yifan , Jiang Nan , Shi Xin
Published: February 2024

Introduction: Exosomes derived from M2 macrophages (M2-Exos) exhibit tremendous potential for inducing tissue repair and regeneration. Herein, this study was designed to elucidate the biological roles of M2-Exos in regenerative endodontic therapy (RET) compared with exosomes from M1 macrophages (M1-Exos). Methods: The internalization of M1-Exos and M2-Exos by dental pulp stem cells (DPSCs) and human umbilical vein endothelial cells (HUVECs) was detected by uptake assay. The effects of M1-Exos and M2-Exos on DPSC and HUVEC behaviors, including migration, proliferation, odonto/osteogenesis, neurogenesis, and angiogenesis were determined in vitro. Then, Matrigel plugs incorporating M2-Exos were transplanted subcutaneously into nude mice. Immunostaining for vascular endothelial growth factor (VEGF) and CD31 was performed to validate capillary-like networks. Results: M1-Exos and M2-Exos were effectively absorbed by DPSCs and HUVECs. Compared with M1-Exos, M2-Exos considerably facilitated the proliferation and migration of DPSCs and HUVECs. Furthermore, M2-Exos robustly promoted ALP activity, mineral nodule deposition, and the odonto/osteogenic marker expression of DPSCs, indicating the powerful odonto/osteogenic potential of M2-Exos. In sharp contrast with M1-Exos, which inhibited the neurogenic capacity of DPSCs, M2-Exos contributed to a significantly augmented expression of neurogenic genes and the stronger immunostaining of Nestin. Consistent with remarkably enhanced angiogenic markers and tubular structure formation in DPSCs and HUVECs in vitro, the employment of M2-Exos gave rise to more abundant vascular networks, dramatically higher VEGF expression, and widely spread CD31+ tubular lumens in vivo, supporting the enormous pro-angiogenic capability of M2-Exos. Conclusions: The multifaceted roles of M2-Exos in ameliorating DPSC and HUVEC functions potentially contribute to complete functional pulp–dentin complex regeneration.

Authors: Verdecchia Nicole , Praslick Alexander , Visoiu Mihaela
Published: February 2024

Introduction: Nerve block catheters (NBCs) are increasingly used for pain management in pediatric trauma patients. While short-term efficacy has been well established, the long-term safety of NBCs is unknown. Methods/Cases: The retrospective chart review includes a cohort of nine pediatric trauma patients aged 3–15 years who received 52 peripheral nerve block catheters and epidurals for pain management. This study aimed to investigate the potential risks associated with the prolonged use of NBCs in pediatric trauma cases. Results: The NBCs (48 peripheral catheters and 4 epidural catheters) were maintained for about 2 weeks. The number of catheters per patient varied from 1 to 11. The study noted a low frequency of catheter-related complications. No catheter-site infection or local anesthetic toxicity symptoms were reported. Discussion: These findings suggest that NBCs can be safely maintained for extended periods in pediatric trauma patients without significantly increasing complications. Careful monitoring and adherence to infection control practices remain paramount when implementing extended catheter use.

Published: February 2024

Although advances in obstetric and neonatal care have improved the survival of preterm infants, many studies document the increased risk of motor and sensory neurodevelopmental abnormalities that can hinder school progress. The aim of this study was to analyze the differences in gross and fine motor development in children born preterm and full term aged 3 to 6 years using the Peabody Developmental Motor Scales 2 (PDMS-II). Fifteen preterm and fifteen term children, matched for age and sex, participated in this study. They were evaluated with the PDMS-II scale. The scores obtained in the PDMS-II scale showed statistically significant differences (p < 0.05) in all subscales except for the “grasping” subscale. No dissimilarities were found between children who attended an early intervention program and those who did not participate, nor was there any correlation between week of gestation and birth weight and motor development in preschool. The results obtained show that differences are found with respect to motor development, with lower scores for those born preterm compared to children born at term. No statistically significant difference was found between preterm children who attended early intervention and those who did not. No correlation was found between motor development at preschool age and birth weight and gestational age.
Lithium Content and Its Nutritional Beneficence, Dietary Intake, and Impact on Human Health in Edibles from the Romanian Market

Published: February 2024

Lithium (Li) is present in human nutrition based on food intake, and several studies recommend it for treating mood disorders, even if the biological proprieties and biochemical mechanisms represent the basis for its use as an essential element. The Li content was evaluated using the inductively coupled plasma mass spectrometry technique (ICP-MS) in 1071 food and beverage samples from the Romanian market. The results show that Li had a decreasing mean concentration in the food samples as follows: vegetables leafy > bulbous > fructose > leguminous > egg whites > root vegetables > milk products > egg yolks > meats. Approximately a quarter of all data from each dataset category was extreme values (range between the third quartile and maximum value), with only 10% below the detection limit. Mean Li concentration indicated higher values in red wine, white wines, beers, and fruit juice and lower in ciders and bottled waters. A particular interest was addressed to plants for teas and coffee seeds, which showed narrow amounts of Li. For both food and beverages, two similar matrices, including egg whites and yolks and white and red wines, were found to have significant differences, which explains the high variability of Li uptake in various matrices. For 99.65% of the analyzed samples, the estimated daily intake of Li was below the provisional subchronic and chronic reference dose (2 µg/kgbw/day) for adverse effects in several organs and systems. Even so, a risk occurs in consuming bulbous vegetables (Li > 13.47 mg/kg) and fructose solano vegetables (Li > 11.33 mg/kg). The present study’s findings indicate that ingesting most of the analyzed beverages and food samples could be considered safe, even if future studies regarding Li content, nutritional aspects, and human cohort diseases must be conducted.
Development and Effect Evaluation of an Action-Oriented Interdisciplinary Weaning Protocol for Cuffed Tracheostomy Tubes in Patients with Acquired Brain Injury
Authors: Bjerrum Katje , Grove Linda-Maria Delgado , Mortensen Sine Secher , Fabricius Jesper
Published: February 2024

The objective was to develop an interdisciplinary weaning protocol (IWP) for patients with tracheostomy tubes due to acquired brain injury, and to effect evaluate implementation of the IWP on decannulation rates and weaning duration. An expert panel completed a literature review in 2018 to identify essential criteria in the weaning process. Based on consensus and availability in clinical practice, criteria for guiding the weaning process were included in the protocol. Using the IWP, dysphagia is graded as either severe, moderate, or mild. The weaning process is guided through a protocol which specified the daily duration of cuff deflation until decannulation, along with recommendations for treatment and rehabilitation interventions. Data from 337 patient records (161 before and 176 after implementation) were included for effect evaluation. Decannulation rate during hospitalization was unchanged at 91% vs. 90% before and after implementation (decannulation rate at 60 days was 68% vs. 74%). After implementation, the weaning duration had decreased compared to before implementation, hazard ratio 1.309 (95%CI: 1.013; 1.693), without any increased risk of tube-reinsertion or pneumonia. Furthermore, a tendency toward decreased length of stay was seen with median 102 days (IQR: 73–138) and median 90 days (IQR: 58–119) (p = 0.061) before and after implementation, respectively. Scientific debate on weaning protocols for tracheostomy tubes are encouraged.

Published: February 2024

Camellia chekiangoleosa is an economically important woody plant from the Genus Camellia in Theaceae, and its seed kernels are rich in edible oils of high health value. Yet, little is known about the molecular regulation of growth and development in C. chekiangoleosa. In this study, we characterized the MYB (Myeloblastosis) gene family that was widely involved in plant development and stress responses, and identified 235 members from the C. chekiangoleosa genome. Based on transcriptomic analysis of multiple tissues, we obtained tissue-specific expression profiles of the MYB genes. We found that 37 MYB genes were highly expressed during seed development, and among them, CcMYB33 (GAMYB) was specifically expressed in the seed coat, suggesting that it may be an important regulator. We cloned full-length sequences of the CcMYB33 gene and further analyzed its sequence characteristics and expression pattern. Our results indicated that CcMYB33 is an R2R3-type MYB transcription factor that is closely related to GAMYB genes of Arabidopsis thaliana. We showed that ectopic expression of CcMYB33 in Arabidopsis lines caused pleiotropical developmental defects, including abnormal leaves, fused stamen, and early flowering, among other things. This work identified important MYB regulators in the regulation of development and growth in C. chekiangoleosa, providing support for further molecular and genetic studies.

Published: February 2024

Cardiovascular disease (CVD) and chronic kidney disease (CKD) often coexist and have a major impact on patient prognosis. Organ fibrosis plays a significant role in the pathogenesis of cardio-renal syndrome (CRS), explaining the high incidence of heart failure and sudden cardiac death in these patients. Various mediators and mechanisms have been proposed as contributors to the alteration of fibroblasts and collagen turnover, varying from hemodynamic changes to the activation of the renin–angiotensin system, involvement of FGF 23, and Klotho protein or collagen deposition. A better understanding of all the mechanisms involved has prompted the search for alternative therapeutic targets, such as novel inhibitors of the renin–angiotensin–aldosterone system (RAAS), serelaxin, and neutralizing interleukin-11 (IL-11) antibodies. This review focuses on the molecular mechanisms of cardiac and renal fibrosis in the CKD and heart failure (HF) population and highlights the therapeutic alternatives designed to target the responsible pathways.
Dynamic Locking Plate versus Multiple Cancellous Screws for the Fixation of Intracapsular Femoral Neck Fractures: Long-Term Results and Quality-Of-Life Assessment Based on Patient-Reported Outcome Measures
Authors: Krupik Yoav , Haziza Sagie , Thein Ran
Published: February 2024

The purpose of this study was to compare the long-term clinical outcomes and quality-of-life measures for two fixation methods in the setting of displaced femoral neck fractures. The two groups included fixation with multiple cancellous screws (group 1) and telescopic femoral neck screws and a small locking plate device (Targon FN) (group 2). Patients underwent reduction and internal fixation with either multiple cancellous screws or the Targon FN device from March 2000 to January 2012. Failure endpoints included nonunion, osteonecrosis of the femoral head, and revision surgery. Patient-reported outcome measures included chronic pain, ability to ambulate, and the use of ambulation assistive devices. Statistical analysis demonstrated a statistically significant lower rate of non-union and overall complication in the Targon FN group (p value < 0.001 and p value = 0.005, respectively). Logistic regression analysis showed that operative fixation with the Targon FN device decreased the odds ratio for overall complication by a factor of 0.34 (p = 0.02). There were no statistically significant differences between groups 1 and 2 in patient-reported outcomes (chronic pain (p = 0.21), ability to ambulate (p = 0.07), and the use of an ambulation assistive device (p = 0.07)). When compared to traditional cancellous screw fixation of femoral neck fractures, the Targon FN device has significantly lower complication rates and equivalent patient-reported outcomes.
The Role of Fundamental Movement Skills and Spatial Abilities in the Relationship between Physical Activity and Mathematics Achievement in Primary School Children
Authors: Scott Jessica , Jay Tim , Spray Christopher M.
Published: February 2024

Research has demonstrated positive relationships between fundamental movement skills (FMS) and mathematics achievement in children, and this relationship may be mediated by spatial ability. Engaging in physical activity (PA) may also have positive outcomes on mathematics achievement; however, no study has investigated this network of relationships together. This study aimed to examine the relationship between PA and mathematics achievement, and the mediating effects of FMS and spatial abilities, in primary school children. Using a cross-sectional design, data were collected from 182 children (aged 7 to 8 years old) across four schools in England. Objective moderate-to-vigorous PA (MVPA) levels and subjective parental reports of their children’s PA participation were collected. Children’s FMS were assessed, along with their performance on four spatial ability tasks and a mathematics test. Mediation analyses revealed no significant mediation effects of FMS and spatial abilities on the positive significant relationship between MVPA and mathematics achievement; however, spatial ability partially mediated the relationship between FMS and mathematics achievement. These results suggest that FMS and spatial ability may not be related to MVPA in this network of relationships, but children with more mature FMS perform better in mathematics due to them performing better on specific spatial ability tasks.
Doppler and Channel Estimation Using Superimposed Linear Frequency Modulation Preamble Signal for Underwater Acoustic Communication
Authors: Lv Chenglei , Sun Qiushi , Chen Huifang , Xie Lei
Published: February 2024

Due to the relative motion between transmitters and receivers and the multipath characteristic of wideband underwater acoustic channels, Doppler and channel estimations are of great significance for an underwater acoustic (UWA) communication system. In this paper, a preamble signal based on superimposed linear frequency modulation (LFM) signals is first designed. Based on the designed preamble signal, a real-time Doppler factor estimation algorithm is proposed. The relative correlation peak shift of two LFM signals in the designed preamble signal is utilized to estimate the Doppler factor. Moreover, an enhanced channel estimation algorithm, the correlation-peak-search-based improved orthogonal matching pursuit (CPS-IOMP) algorithm, is also proposed. In the CPS-IOMP algorithm, the excellent autocorrelation characteristic of the designed preamble signal is used to estimate the channel sparsity and multipath delays, which are utilized to construct the simplified dictionary matrix. The simulation and sea trial data analysis results validated the designed preamble, the proposed Doppler estimation algorithm, and the channel estimation algorithm. The performance of the proposed Doppler factor estimation is better than that of the block estimation algorithm. Compared with the original OMP algorithm with known channel sparsity, the proposed CPS-IOMP algorithm achieves a similar estimation accuracy with a smaller computational complexity, as well as requiring no prior knowledge about the channel sparsity.
On the Role of Informal vs. Formal Context of Language Experience in Italian–German Primary School Children

Published: February 2024

This study focuses on the contexts of language experience in relation to language dominance in eighty-seven Italian–German primary school children in Germany using the MAIN narrative task. We compare current language experience in the heritage language (Italian) and the majority language (German) in both formal and informal settings, and we examine the respective impact on micro- and macrostructure measures, including different language domains. Some previous findings emphasized the importance of language experience in formal contexts. By contrast, our results suggest that, in particular, language experience in informal contexts determines vocabulary and fluency in the heritage and majority language, while there are no effects of exposure on syntactic complexity. Furthermore, while the younger children are relatively balanced, the older children are more dominant in the societal language. Our findings imply that the use of the minority language in informal contexts should be encouraged to promote its development and maintenance.

Published: February 2024

Visceral leishmaniasis (VL) is a parasitic zoonosis caused by Leishmania spp. that usually manifests itself in immunocompromised subjects. It is a rare and neglected disease, and it is not endemic in the province of Brescia (Italy). Three cases of human VL occurred in Brescia from October to December 2021 in immunocompetent patients. We evaluated the patients looking for signs of underlying immunodeficiencies and conducted further epidemiological evaluations in the province of Brescia without success. An analysis of the sera levels of the main cytokines involved in the immune response to VL was performed. All patients presented a significant augmentation of CXCL-10, CCL-4, and IL-6. The patients tested during the acute phase showed an elevation of IL-1α, IL-5, IL-10, and IL-12, while in the recovery phase, higher levels of TNF-α and IL-7 were detected. Altogether, a predominant activation of the T-helper-2 pathway emerged during the acute phase of the parasite infection, while the cytokines associated with the T-helper-1 pathway were less represented. This imbalanced immune response to the parasite infection might play a crucial role in the development of VL in immunocompetent patients.
Cyclodextrin-Enabled Enantioselective Complexation Study of Cathinone Analogs

Published: February 2024

The characteristic alkaloid component of the leaves of the catnip shrub (Catha edulis) is cathinone, and its synthetic analogs form a major group of recreational drugs. Cathinone derivatives are chiral compounds. In the literature, several chiral methods using cyclodextrins (CDs) have been achieved so far for diverse sets of analogs; however, a comprehensive investigation of the stability of their CD complexes has not been performed yet. To characterize the enantioselective complex formation, a systematic experimental design was developed in which a total number of 40 neutral, positively, and negatively charged CD derivatives were screened by affinity capillary electrophoresis and compared according to their cavity size, substituent type, and location. The functional groups responsible for the favorable interactions were identified in the case of para-substituted cathinone analog mephedrone, flephedrone, and 4-methylethcathinone (4-MEC) and in the case of 3,4-methylendioxy derivative butylone and methylenedioxypyrovalerone (MDPV). The succinylated-β-CD and subetadex exhibited the highest complex stabilities among the studied drugs. The complex stoichiometry was determined using the Job’s plot method, and the complex structures were further studied using ROESY NMR measurements. The results of our enantioselective complex formation study can facilitate chiral method development and may lead to evaluate potential CD-based antidotes for cathinone analogs.
The Design of a Photonic Crystal Fiber for Hydrogen Cyanide Gas Detection

Published: February 2024

Hydrogen cyanide gas is a dangerous and fatal gas that is one of the causes of air pollution in the environment. A small percentage of this gas causes poisoning and eventually death. In this paper, a new PCF is designed that offers high sensitivity and low confinement loss in the absorption wavelength of hydrogen cyanide gas. The proposed structure consists of circular layers that are located around the core, which is also composed of circular microstructures. The finite element method (FEM) is used to simulate the results. According to the results, the PCF gives a high relative sensitivity of 65.13% and a low confinement loss of 1.5 × 10−3 dB/m at a wavelength of 1.533 µm. The impact of increasing the concentration of hydrogen cyanide gas on the relative sensitivity and confinement loss is investigated. The high sensitivity and low confinement losses of the designed PCF show that this optical structure could be a good candidate for the detection of this gas in industrial and medical environments.
Charisma and Memory in a Spiritual Community: The Case of Damanhur in Italy
Authors: Ghio Alberto
Published: February 2024

This paper explores the dynamic relationship between the spiritual community of Damanhur and its founder, Oberto Airaudi. Scholars consider Airaudi to be an example of Weberian charismatic leadership that was sui generis; the community, however, experienced an early routinisation, which granted it longevity and stability. Doctrinal and social evolution instead suggests a change in this charismatic relationship over the years, which occurred in four phases. His charisma passed from the ability to perform occult practices (occultist), to ideate a syncretic cosmology centred on Damanhur (religious), eventually allowing him to become an “inspirer from the outside” (inspirational). The last phase explains the survival and partial routinisation of the charisma after his death (post mortem). The study primarily relies on the analysis of Damanhurian writings, with a particular focus on the initial ten years. It also incorporates qualitative data from fieldwork and ethnographic material available in the scientific literature. The analysis suggests that Damanhur did not start as a charismatic community but as a social experiment. The development of Airaudi’s charisma, via a syncretic mythology based on a religious concept of memory, absorbed Damanhur’s social dimension, shaping it according to a collective spiritual endeavour aimed at reconnecting human beings with their divine inner nature.
Preaching beyond Binary Categories: An Approach from Process Theology
Authors: Allen Ronald J.
Published: February 2024

Thinking in binary categories has often characterized both the Christian community and communities beyond the church. This pattern of mental operation typically sees binary categories as self-contained and often as mutually exclusive, e.g., male/female, judgment/salvation, and religious/secular. However, some interpreters call binary thinking into question and point to possibilities of more nuanced perspectives, perhaps most well-known with respect to more expansive views of gender: the categories of male and female are not mutually exclusive but are reference points among clusters of sexual and gender expression and preferences. Process theology offers preachers ways to transcend binary exclusivism. Several convictions of process thought come into play: the divine aim that all things work together for optimum becoming, the dipolar nature of God, the internal relationship of all things, and especially the perception that a binary is an invitation for creative transformation in thinking beyond the binary pattern about how the elements in the field of the binary might relate with one another so as to honor diversity as part of moving towards optimum becoming. The article begins with a statement of the problem, summarizes key elements of process thought that come into play, sketches how a preacher might seek the creative transformation of binary impasses, and brings forward three case studies of binaries that illustrate this approach in action.
A Legacy Lost to the Reformed Imagination: Luther and Confessional Lutheranism on the Extent of the Atonement
Authors: Hartog Paul Anthony
Published: February 2024

The “Young, Restless, Reformed” movement has sought to establish itself upon reformational foundations rooted within the sixteenth century. The new movement’s undertaking, however, has virtually ignored the differences between its own adherence to “limited atonement” and the developed theology of Martin Luther. Even on an academic level, the legacy of gratia universalis ensconced within confessional Lutheranism has been largely lost to the Reformed imagination. This article focuses upon relevant materials in Luther’s Lectures on Galatians (1531/1535) and his Sermon on John 1:29 (1537), as well as the pertinent statements found within early Lutheran confessions. What emerges is a Lutheran tradition that espoused both “unconditional election” and a robust form of “unlimited atonement,” a divine provision of redemption and satisfaction for all. In Lutheran theology, this provision in Christ extra nos serves as an objective foundation for confident faith. As contemporary Reformed scholars increasingly delve into the diversity of the Reformed tradition within early modernity, the distinctive Lutheran voice is another legacy worth remembering.
Propagating the Rosary in the Early Qing—A Case Study of del Rosario’s Comprehensive Manuscript
Authors: Yang Hongfan
Published: February 2024

Studies on the Rosary in the late Ming and early Qing usually focus on works written by Jesuits and mostly stem from an artistic aspect. This article, however, shifts the focus to The True Peace of Humankind, a manuscript written by the Dominican missionary Arcadio del Rosario in the seventeenth century, the first comprehensive book on the Rosary in Chinese. It first summarizes the early-stage propagation of the Rosary in China by the Jesuits and then examines the structure and content of The True Peace of Humankind. It is noteworthy that the manuscript repeatedly uses an analogy with flowers to highlight Mary’s intercession. Dating back to the Catholic tradition in Europe, the propagation of the Rosary through analogy with flowers resembles the propagation of reciting Buddhist prayers in Chinese society. This article applies contextual studies to explore two main questions: how is del Rosario’s manuscript different from the previous texts on the Rosary written by the Jesuits? What is the significance of the manuscript in the context of the Chinese Rites Controversy?
On the Possibility of a Static Universe

Published: February 2024

After a century of cosmological observations, we have a solid standard model of cosmology. However, from a theoretical viewpoint, it is a compelling question if the cosmological data inevitably require an expanding universe independently of the theoretical framework. The possibility of obtaining a viable cosmological model with a constant scale-factor is discussed in the context of the Brans–Dicke class of scalar–tensor theories. It is shown that a flat spatial section requires the presence of a stiff matter fluid. However, some kinematical properties of the standard cosmological model can be reproduced. A realistic scenario may require a more complex class of scalar–tensor theories.

Religious families are families in which faith and religion play an important role in daily life and influence the relationships between family members. These relationships, in turn, can be diverse and depend on the particular beliefs and practices of each family. One of the characteristics of relationships in religious families is that they are based on shared beliefs and values. Religion can provide a basis for building unity and solidarity in the family, as faith and religious practices can become central elements of daily life. This can create increased and prolonged contact between family members and strengthen their understanding and support for each other. However, relationships in religious families can also be subject to stress and strain. This can be due to the strict requirements and rules set by religious teachings, which can create conflicts and discrepancies between family members. For example, disobedience to religious law or a change of religion by a family member can cause disagreements and breakdowns in relationships.

The article examines Russian-Chinese relations in the context of the emergence of a new world order. The author emphasizes that Russia and China consider each other as priority partners, always respect each other’s interests, becoming a model of relations between great powers. The countries maintain close exchanges and contacts at all levels, exchange views on major issues of mutual interest, strengthen mutual trust and develop cooperation in various fi elds. Russia and China have always adhered to the principles of non-alignment with blocs, non-confrontation, and they are not directed against a third party. They develop bilateral relations and cooperation in various fi elds on the basis of mutual respect, equality and mutual benefi t, which brings tangible benefi ts to the people of the two countries and also contributes to global development. China and Russia take common positions on most issues on the international agenda and are strengthening cooperation within the UN, SCO, BRICS, APEC, G20 and other multilateral platforms. They cooperate closely on global and regional issues, such as the Korean Peninsula nuclear issue, the situation in Afghanistan and the Iranian nuclear issue. When Russia and China join forces, global multipolarity and democratization of international relations will receive new impetus, which will guarantee global strategic balance and stability. Meetings between the leaders of Russia and China become the compass and anchor of Russian-Chinese relations, laying a solid foundation for deepening bilateral cooperation. Under the strategic leadership of the two heads of state, the Russian-Chinese relations of comprehensive partnership and strategic cooperation will continue to move forward in the new era. The leaders of China and Russia agree that against the backdrop of unprecedented changes taking place today in the system of international relations, Russian-Chinese relations have reached unprecedented heights. The author comes to the conclusion that, in general, Russian-Chinese relations have not only withstood many new challenges, but have also strengthened signifi cantly over the past year.

This study uses intelligent techniques to regulate brushless direct current speed (BLDC) motors. After these motors solved the problem of using brushes and commutators in traditional DC motors, they succeeded in replacing brushes and commutators with electronic commutators. Due to the use of electronic switching, brushless motor algorithms are more complex than those of conventional motors. In this study, to adjust the PID controller's settings (Kp, Ki, and Kd), a trial-and-error approach was taken, and a completely new method known as the settings of known PID controllers have been modified using the new Gray Wolf algorithm. A BLDC motor's main benefit is that it has easy speed adjustment across a broad range, whereas AC motors often cannot be controlled in this way. Through the use of Matlab/Simulink, the BLDC motor's mathematical model was developed and implemented. The simulation results show that in the first case, a PID controller effectively induces the turbulent dynamic behavior of BLDC under load and no-load conditions, and in the second case, the speed shows the lowest rise time, stability, overshoot, and stability conditions, and performs at its best. The characteristics of the traditional PID controller that regulates the engine speed must be regulated online to achieve the use of intelligent technologies, and the adjustment is done online using the neural network. The results showed that this technology, or feature - online tuning - is the most effective and reliable of all.

Published: February 2024

Image segmentation is the process of automatically dividing an image into distinct, meaningful, and non-overlapping regions. The quality of the segmentation process determines the efficiency of other image processing tasks. Analyzing microstructural images is crucial since the mechanical properties are strongly dependent on the microstructural phases’ statistics. These images are considered one of the most difficult and challenging images to deal with due to their special characteristics, such as the convergence in pixels intensity values, overlapping in colors, boundaries and textures in phase regions, infinite shapes of grains and colonies, etc. As there is no generic technique suitable to be used with all microstructures, this work reviews techniques that have been effectively used and recommended to be employed in metallurgical research, with a brief description of their principles, advantages, and disadvantages, and discusses their applicability. The major aim of this work is to spare time and effort searching for and experimenting with all the available methods for future researchers.

This paper explores the significance of energy conservation in the context of rising energy consumption and its impact on economic growth. With a focus on cooling systems, particularly evaporative condenser technology, the study aims to investigate its fundamentals, operating principles, and theoretical aspects. The paper delves into the various types of condensers used in cooling systems, emphasizing the role of evaporative condensers in enhancing heat transfer efficiency. The operating principles of evaporative condensers are detailed, considering factors such as air and water flow rates, wet bulb temperatures, and heat transfer coefficients. Theoretical models and mathematical approaches for evaluating evaporative condenser performance are also reviewed. The research includes an extensive review of existing literature on evaporative condenser technology, covering refrigeration models, HVAC systems, and various experimental studies. Theoretical models are discussed, highlighting the challenges in accurately modeling evaporative condenser behavior. The paper also presents achievements and advancements in research, including experiments that demonstrate the positive impact of evaporative cooling on air-cooled condenser systems. Various case studies and experimental validations showcase the potential energy savings and improved performance achieved through the incorporation of evaporative condensers in cooling systems. By switching from an air-cooled to an evaporatively-cooled condenser, one can reduce electricity consumption by 58%, according to research. This alternate condenser type improves performance by 113.4% at from 3 to 3000 kW of cooling power.
A Numerical Study of Blade Geometry Effects in a Vertical-Axes Wind Turbines

Published: February 2024

Several geometrical elements influence the aerodynamic properties of the Darrieus vertical axis wind turbines (VAWTs). Many extant studies have examined properties, such as solidity, pitching axis position (x/c), length of chord (c), blade quantity (N), diameter (d) of the rotor, and aspect ratio. However, not many have examined the shape of the airfoil (AF), which is a vital property that remains to be thoroughly investigated. Therefore, this present study used computational fluid dynamics (CFD) to investigate many airfoils blade characteristics, such as blade thickness (BT), maximum camber ratio (MCR), MCR location (MCRL), and air speed (AS), to determine their impact on VAWT performance. The results demonstrate a blade thickness BT of 10 to 12%, MCR of 0 to 22%, and MCRL of 24 to 23% yield a comparatively high coefficient of power, adequate optimal blade rotation to airspeed ratio (TSR), broader operational area, and high band efficiency while air velocities of 15 to 10% yield a comparatively higher power coefficient.
