A scientometric analysis of applied linguistics research (1970–2022): methodology and future directions
Authors: Zakaria Azrifah , Aryadoust Vahid
Published: January 2023

In this study, we provide a scientometric analysis of 43,685 studies published in 51 quartile-1 journals in the field of applied linguistics (1970–2022). Scientometric analysis uses citation records to quantitatively compute networks of cited works and map out how published works have been cited. We adapted a multi-stage scientometric method consisting of database identification, dataset generation, document co-citation analysis, research cluster identification, and cluster characterization. A number of major research clusters were identified and a high degree of interconnectedness in terms of theoretical base was observed between the clusters. The pre-2000 publications had a conspicuous focus on theories derived from language use, which might be said had set the tone for the maturation of the field. By contrast, the clusters that emerged from the 2000s showed more specificity and granularity in focus and scope, suggesting the beginning of a research era with more specialized directions. Despite this trend, we identified influential publications which received several spikes in citations in different eras, indicating their continued temporal and thematic relevance in different clusters. In addition, we found evidence of inter-cluster cross-pollinations. We discuss how each cluster should be characterized in terms of its knowledge base and knowledge front. Highly cited works form the knowledge base of a cluster while novel works form the knowledge fronts of a cluster. Future directions are mentioned and highlighted.

Authors: Keykha Mohsen , Hosseni Mohsen
Published: January 2023

Considering the ever-increasing human need for energy resources and on the other hand, the reduction of fossil fuel resources, the use of renewable energy has become one of the attractive topics of researchers. One of the available and ambient sources in nature is mechanical energy in nature, such as the energy of body movements, wind energy, energy in sea waves, etc. One of the methods of converting and extracting energy from the mentioned forms is the use of triboelectric nano generators. Triboelectric nanogenerators have various structures. In the current research, the contact mode and two electrodes of triboelectric nanogenerators have been discussed and also the relationships governing the nano generator have been calculated. By comparing the response of the nano generator in ideal and non-ideal state, it can be understood that considering the effects of edge capacitors will be effective on the final response of the nano generator. Finally, the effect of various parameters on the performance of the triboelectric nano generator has also been investigated.

This paper presents the evolution of bidirectional electric vehicle charger for G2V (i.e., Grid-to-Vehicle) and V2G (i.e., Vehicle-to-Grid) utility. Electric vehicle are growing day by day in the area of transportation. As more electric vehicles hit the road to maintain the need for charging, bidirectional charging becomes essential. Bidirectional charging in electrical vehicles facilitates users to either make energy flow to the vehicle or flow from the vehicle. The proposed design allows users to make economic gains from electric vehicle with other exciting advantages. Particularly unidirectional charging solution restricts the user to use energy for charging only applications whereas, this paper proposed a control strategy for bidirectional charging of electric vehicles. Hence electric vehicles could be potentially used as a source during an emergency like power outages, grid failure, or whenever there is an excess load on grid and user needs more energy. Additionally, this paper uses an integration of buck and boost converter to develop a bidirectional vehicle charger. The performance of bidirectional converter with control algorithm is verified by simulation on MATLAB Simulink.
Therapeutic antibodies for precise cancer immunotherapy: current and future perspectives
Authors: Liu Longchao , Chen Jiahui
Published: January 2023

Antibodies, as one of the most important components of host adaptive immune system, play an important role in defense of infectious disease, immune surveillance, and autoimmune disease. Due to the development of recombinant antibody technology, antibody therapeutics become the largest and rapidly expanding drug to provide major health benefits to patients, especially for the treatment of cancer patients. Many antibody-based therapeutic strategies have been developed including monoclonal antibodies, antibody-drug conjugates, bispecific and trispecific antibodies and pro-antibodies with promising results from both clinical and pre-clinical trials. However, the response rate and side-effect still vary between patients with undefined mechanisms. Here, we summarized the current and future perspectives of antibody-based cancer immunotherapeutic strategies for designing next-generation drugs.
Redeposition-free inductively-coupled plasma etching of lithium niobate for integrated photonics
Authors: Kaufmann Fabian , Finco Giovanni , Maeder Andreas , Grange Rachel
Published: January 2023

Lithium niobate on insulator is being established as a versatile platform for a new generation of photonic integrated devices. Extensive progress has been made in recent years to improve the fabrication of integrated optical circuits from a research platform towards wafer-scale fabrication in commercial foundries, and optical losses have reached remarkably low values approaching material limits. In this context, argon etching of lithium niobate waveguides has been shown to provide the best optical quality, yet the process is still challenging to optimise due to its physical nature. Namely, the micro-masking effects introduced by the material redeposition and a close to one etch mask selectivity for deep etches. We present a workflow to identify the parameter set offering the best etching results independent of the plasma system being used. We show how to reach the redeposition-free regime and propose three methods to achieve redeposition-free lithium niobate etching with good quality sidewalls without need of wet chemistry for cleaning.
On-chip integration of metasurface-doublet for optical phased array with enhanced beam steering
Authors: Wang Zhizhang , Ji Jitao , Ye Xin , Chen Yuxin , Li Xueyun , Song Wange , Fang Bin , Chen Ji , Zhu Shining , Li Tao
Published: January 2023

Optical phased array (OPA), as a promising beam steering technology, however, usually suffers from a narrow field of view (FOV) that limits its performances in applications. A miniaturized compact strategy to enlarge the beam steering angle is quite desirable for the solid-state OPA technique. Here an on-chip metasurface-doublet is proposed to offer angle magnification integrated with a port-selected optical phased array. It is implemented by combing convex and concave metalenses with the quadratic phase distribution, which is precisely integrated on the OPA chip by layer-by-layer fabrication process. Here, the OPA is fabricated in Lithium Niobate on Insulator (LNOI) platform. Our experiments show that the metasurface-doublet is able to achieve 1.54 times FOV amplification in a horizontal direction and with >41% working efficiency. Our results provide a feasible approach to achieve enlarged FOV for wide-angle beam steering and also imply a powerful platform in developing integrated multilayer metasurface devices.
Extra-auditory effects of noise exposure in Italian schools: noise levels in external areas
Authors: Busa Lucia , Goretti Michele , Guattari Claudia , Pulella Paola
Published: January 2023

Schools in urban areas are often located in areas with high traffic and noise pollution that affect the overall and sonic quality of the external spaces. Due to this, teachers and students are exposed to high noise levels, this condition could have an impact on the perceptive-cognitive and neurobehavioral aspects, determining auditory and extra-auditory effects from exposure to noise. The BRiC - ID14 project, funded by INAIL, investigates the extra-auditory effects of noise exposure on primary and secondary school teachers and students.

In this study, the assessment of sonic, acoustic and overall environment of the external area of three kindergartens, three primary schools and three secondary ones located in Rome, Florence and Perugia was carried out. The external areas were investigated and discussed by analyzing the acoustic, psychoacoustic and subjective data collected. The results obtained by the acoustic measurements campaign under non-occupied conditions were compared with the soundscape measurements outcomes, under occupied conditions. The two measurements campaign revealed that the obtained values are comparable in terms of objective and subjective responses. The differences observed in the perception of the sonic and overall environment are ascribable to different noise sources located close to the schools.

Published: January 2023

Due to the difficulty of accessing quiet urban areas as defined by the EU Directive 2002/49/EC and of designing new ones, especially in the historical centers, it becomes more and more important to recognize pockets of quiet which can provide visitors with time for their physical and mental restoration. To this aim, an investigation methodology has been developed in previous studies conducted in Naples (Italy), Istanbul (Turkey) and Murcia (Spain) focused on finding and characterization of alternative quiet spaces which could offer opportunities to rest from the surrounding noise, which highlighted the role of non-auditory aspects on the restorativeness of urban spaces, such as green and water elements, or of historic and cultural value. This methodology which includes objective and subjective assessment has been used to characterize and illustrate the potentialities of the existing and potential spaces for restoration within the ancient center of the city of Florence (Italy). Concerning acoustic measurements, the “quietness” is confirmed by the fact that the differences between the sound levels (LAeq) of the surrounding areas and those within selected sites is greater than 9 dB; while the outcomes of the survey confirm the expectations especially concerning the importance and relevance, the cultural value, the historical-artistic elements, the perceived sense of being away and the distinction with the external acoustic environment.

Published: January 2023

This research aims to analyse the relationship between Individual Resilience, as measured by the CD-RISC-10 scale (Campbell and Stein, 2007) and Community Resilience, as measured by the Index of Perceived Community Resilience (IPCR, Kulig et al., 2013), in a sample of 387 people living on the island of Bali (Indonesia). The population of this area regularly faces the consequences of natural disasters, such as earthquakes, volcanic eruptions and severe floods. A Confirmatory Factor Analysis of the IPCR was carried out, which confirmed the multidimensional structure of Community Resilience originally proposed by its authors. Results also showed that there is a positive and moderate correlation between Individual and Community Resilience. Specifically, regression analysis showed that the three Community Resilience factors explain 32% of Individual Resilience, although Leadership followed by Community Engagement are the two factors that provide the most explanatory power.

Published: January 2023

This article presents an analysis of Femicide, as an extreme practice of violence against women based on the roots of historical-cultural patterns where the male sex is shown as dominant and the submission of the female. Hermeneutics was used as a method to study the texts from a critical stance. In the same way, techniques such as bibliographic matrices and content analysis were used that favored the processing of knowledge and the establishment of trends, essential elements to be able to form a theoretical framework with relevant information about the subject in question. Corroborating through the study carried out that in the reference investigations the objectives have been channeled from different professional fields and under a merely informative vision, with a limited look at the causes that generate it. Demonstrating a vision more of effect than causality, therefore, proactive and contextualized research is needed to empower women to transform their reality.

Oridonin protects hydrogen peroxide-induced human lens epithelial cell damage by regulating the NLRP3/NF-κB pathway and Nrf2-mediated oxidative stress
Authors: Chen Jie , Zeng Wei , Xiao Xili , Lin Chengmin
Published: January 2023

Cataract is the clouding of eye lens, and is the leading cause of visual impairment and blindness worldwide. There is an urgent need to develop new drugs to combat this disease. Oridonin (ORI), isolated from Rabdosia rubescens, is a natural substance that has been studied as an activator of nuclear factor erythroid 2-related factor 2 (Nrf2) and covalent inhibitor of NLR family pyrin domain containing 3 (NLRP3). Whether ORI has a therapeutic effect on human lens’ epithelial cell injury needs further study. In this study, we used cataract lens epithelial cell lines HLE-B3 and SRA01/04. We found using the MTT assay that ORI treatment increased cell viability induced by hydrogen peroxide (H2O2). In addition, ORI suppressed the apoptosis of H2O2-induced HLE-B3 and SRA01/04 cells detected by flow cytometry and Western blot analysis. Our data further revealed that ORI regulated nuclear factor, erythroid 2 (NFE2) like bZIP transcription factor 2 (Nrf2)-mediated oxidative stress by enzyme-linked-immunosorbent serologic assay. We further found that ORI inhibited NLRP3/nuclear factor-κb (NF-κB) pathway in H2O2-induced HLE-B3 and SRA01/04 cells by Western blot analysis. Therefore, these results suggested that ORI could have the potential to serve as a promising drug to treat cataract.
Greek Topicalization: How do properties move?
Authors: Georgiou Renos
Published: January 2023

This paper argues that Greek topicalization is an A’-movement dependency which is headed by a property-denoting phrase (i.e., of type ), dislocated to a left peripheral topic position (spec,TopicP). Crucially, at the syntax-semantics interface, the dislocated topic phrase must undergo total reconstruction, which means that topicalization is obligatorily mapped to a logical form which only comprises the copy of the topic phrase in the thematic position. Through the study of Greek topicalization I examine the syntax-semantics mapping for movement chains that involve property-phrases (type ), showing that such a movement chain could not be mapped onto an individual variable or a property-denoting trace. More generally, the present paper provides novel empirical evidence for the claim that property denoting traces do not exist in natural languages (Poole 2017; 2022). As a result, topicalization resorts to total reconstruction as the only logical form which can be directly interpreted by the semantic component.
Can you judge what you don’t hear? Perception as a source of gradient wordlikeness judgements
Authors: Kahng Jimin , Durvasula Karthik
Published: January 2023

A key observation about wordlikeness judgements, going back to some of the earliest work on the topic is that they are gradient in the sense that nonce words tend to form a cline of acceptability. In recent years, such gradience has been modelled as stemming from a gradi­ent phonotactic grammar or from a lexical similarity effect. In this article, we present two experiments that suggest that at least some of the observed gradience stems from gradience in perception. More generally, the results raise the possibility that the gradience observed in wordlikeness tasks may not come from a gradient phonotactic/phonological grammar.
Dancing Calgon: Embodied Research through Motif Notation
Authors: Heiland Teresa Louise , Taylor Mandi , Jensen Marlene , Morikawa Stephanie
Published: January 2023

This embodiment study is presented in video from the qualitative analysis of two dancers’ experiences with dancing and writing using Motif Notation as they engaged in the practice of learning a dance from video. They interpreted their scores, revised the notation, and performed for accuracy. Through the dancers’ voices, movement, and Motif Notation scores, the study captures dancers’ experiences of how score writing can inform embodiment of an unfamiliar dance style. The dancers shared their self-discovery processes of using intellect to deepen embodiment—and embodiment to deepen intellect. The study with these two dancers revealed that (1) Motif Notation deepens cognitive, social-emotional, and psychomotor learning, and (2) notating while learning movement supports the concept of a dancer as a “researcher,” one who investigates in order to clarify meaning and improve embodiment. This study is IRB approved.

Anayasada yerel yönetimler arasında sayılan il özel idarelerinin özerkliği tartışılırken büyükşehirlerde görevlerine son verilmesi tartışmayı daha da arttırmıştır. Her ne kadar merkezden bağımsızlığını sağlayamamış olsa da kırsal alanda hizmet veren il özel idarelerinin kaldırılması hizmetin halktan uzaklaşmasına neden olmuştur. İşte bu tartışmalar içerisinde 51 ilde çalışmalarına devam eden il özel idareleri daha çok önem arz etmektedir. Kamu hizmetinin kalitesinin artması için personelin liyakate uygun işe alımının yanında eğitimi ve geliştirilmesi de önem taşımaktadır. Çalışmanın konusu; Elâzığ ve Kars İl Özel İdarelerinde insan kaynaklarını eğitmeye ve geliştirmeye yönelik uygulamalardır. Amacı ise bu uygulamaları tespit etmek, niceliğini ve niteliğini anlamak ve il özel idareleri arasında bir karşılaştırma yaparak genel resmi görmektir. Araştırma nitel yaklaşımla gerçekleştirilen bir durum çalışmasıdır. Araştırmanın verileri; Elâzığ ve Kars İl Özel İdarelerinde insan kaynakları sorumlularıyla gerçekleştirilen yapılandırılmış yüz yüze görüşmeden elde edilmiş ve kurumların internet sitelerinden elde edilen dokümanlarla desteklenmiştir.

Operative procedure considered to be a challenging for operator technically in order to provide favourable outcome. Minimally invasive procedure has been carried out frequently over the decade but none of them have shown better prognosis including esthetic treatment. Treatment of initial demineralisation of enamel surface could lead to caries progression. So, it’s very difficult to understand the buffering activity and ph of oral environment which differ from one person to another.

To overcome initial demineralisation operator should have thorough knowledge of tooth anatomy, diagnosis and histopathology of caries. Previous diagnostic methods are bit cumbersome but future techniques are yet to be introduced into clinical usage recently resin infiltration was introduced as therapeutic treatment to prevent further subsurface demineralization of enamel. Present clinical procedure considered to be a non-invasive method. So early detection and proper diagnosis considered to be important than treatment protocol.
A noval autogenous pulp capping material: A case report
Authors: V R Rakshith , R Purushothama , M R Samrat , R Sujith , G Kavitha , DR Balaji
Published: January 2023

Vital pulp therapy for cariously exposed permanent teeth remains one of the most controversial areas in dentistry. Because a vital pulp is capable of initiating several defence mechanisms to protect the tooth from bacterial invasion, hence it is beneficial to preserve the vitality and health of an exposed pulp rather than replace it with artificial material following pulp exposure. There is no consensus on the survival rate of formerly cariously exposed pulps.

Observation time, diagnostic criteria, pulpotomy/pulp capping technique and most importantly, pulpal status at the time of treatment, vary to a great extent amongst studies. In mature teeth, a pulp exposed by caries is usually removed and the root canals are cleaned, shaped and filled. Amongst the methods for preservation of a cariously exposed pulp, direct pulp capping has yielded a markedly high success rate in young teeth. The lack of predictability and long-term success greatly influence decision-making. The decision-making itself is unreliable primarily due to the difficulty of accurately diagnosing the ability of the pulp to repair. While there are various direct pulp capping materials like calcium hydroxide, MTA, Biodentin are considered to be expensive.

PRF known to be bodies own tissue being autogenous graft aids in biological healing kinetics. present clinical procedure utilize PRF as direct pulp capping agent which will probably help pulp for repair and regeneration and also considered to be as clinically feasible procedure .
Immunohistochemistry analysis of estrogen receptor and androgen receptor in benign prostatic hyperplasia and prostate carcinoma
Authors: Aditi Sneha , Naik Ramadas
Published: January 2023

Benign prostatic hyperplasia (BPH) and prostate adenocarcinoma are the most common disorders affecting elderly men. The diseases are androgen-dependent and are treated by obstructing androgen receptor (AR) or their action. AR has direct relationship between the development of prostatic hyperplasia and prostatic carcinoma. Estrogens directly target prostate tissue by definite estrogen receptors (ER). The human prostate is primed with a dual system of ERs (ER-α and ER-β). Use of estrogens as hormonal agents is for suppressing prostatic tissue growth. Study aims to identify, assess and establish the significance of ER and AR as a marker in distinguishing BPH and prostatic carcinoma.

A cross sectional study was conducted at a tertiary care hospital over a period of two year on 65 specimens which included 30 malignant cases and 35 benign cases. Specimens received were tru-cut biopsy, transurethral resection of prostate chips (TURP) and prostatectomy specimen for malignant cases and TURP for benign lesions. Paraffin embedded blocks was stained with H&E and IHC with ER and AR performed on representative sections and graded .the results were assessed for association with various parameters in both benign and malignant cases.

Out of 30 cases of adenocarcinoma of prostate majority of specimens were needle biopsies (54%). The age of presentation was 55-84 years with mean age being 68.93 years. In cases of BPH the presenting age was 35-84 years and mean age was 63 years. Histopathological parameters assessed for malignant lesions, showed negative correlation of grade group with PNI and positive correlation with neutrophils. Higher grade showed adverse histological parameters. %PSA was <25% in malignancy. ER positivity was noted in 80% malignant and 100% benign cases with weaker positivity noted maximum in benign cases. AR positivity was noted in all cases both benign and malignant, with benign cases showing higher intensity.

Hormones play a multifactorial role in the pathogenesis of BPH and prostatic carcinoma; most commonly androgen and estrogen, and can be used towards finding a better therapy.
An unusual visitant in gastric biopsy- A report of two rare cases
Authors: Vallalkani KN  , Sumithra A  , Volga H
Published: January 2023

Granulomatous gastritis (GG) is a subtype of chronic gastritis which may be infectious, non-infectious, or idiopathic in nature. For treating clinicians, granulomatous gastritis has always been a diagnostic challenge because of the same clinical and endoscopic features between Crohn’s disease and tuberculosis. A diagnosis can be reached only by the combination of histopathological examination with clinical and laboratory investigations. Several studies showed that granulomas are more common in the antrum and are generally located superficially within the gastric pit where the gastric bacteria H.pylori are seen, which can cause damage. We are reporting two rare cases of granulomatous gastritis associated with H.pylori in a 40-year-old male and a 43-year-old female with a negative family history of tuberculosis.
Chondrosarcoma of the great toe clinically mimicking osteoclastoma-An unusual presentation
Authors: Akhtar Kafil , Usmani Saman , Lubna Fatma , Irfan Sarah
Published: January 2023

Chondrosarcoma is cartilage forming neoplasm which mostly occurs in pelvis, femur and humerous. Chondrosarcoma is rare in the foot and the involvement of phalanges is extremely rare. It is a malignant neoplasm which mimics various epiphysial tumors clinically and radiologically, so histopathology is the gold standard for confirming the diagnosis. We report an unusual case of Grade II Chondrosarcoma in a 60 years old male, who complained of swelling and pain in left great toe for the past two years, which clinically mimicked Osteoclastoma. Imprint smear from swelling in the left great toe showed scattered mononucleated to binucleated oval to plump to polygonal cells with coarse chromatin and moderate eosinophilic cytoplasm in a chondromyxoid background suggestive of malignancy with differentials of Osteosarcoma and Chondrosarcoma. Histomorphology with immunohistochemistry led to the confirmation of diagnosis of this tumor at a rare site.

Subject of research: the factors and consequences of mobbing against school teachers. To achieve this goal, the methods of in-depth interview and content analysis of domestic film production were used.
Purpose of research: to determine the causes, factors and consequences of mobbing against school teachers.
Methods and objects of research: the empirical basis for the interview method was 25 employees of educational institutions. The empirical base of content analysis of domestic film production was 15 films and TV-series from 1956-2018.
Main results of research: as a result of the article, macro- and micro factors of mobbing against school teachers in the modern educational environment were identified. The first group includes institutional factors reflecting the current stage of education development (the service function of education, the low social status of the teacher, the long-term neglect of the socialization function of education, the introduction of a test system for evaluating schoolchildren, large volumes of accounting documentation). The second group includes socio-psychological and psychological factors ("outdated" models of communication between teachers with experience and students, the psychological climate in the teaching staff (lack of support from colleagues), awareness of the teacher's insecurity, dissatisfaction with professional activities, the "consumer" position of parents, conniving parenting style in the family of a child, low educational motivation of children).

Subject of research: thermal process of welding PE100 saddle branches to polyethylene pipes of existing gas pipelines at low temperatures.
Purpose of research: development of an effective method for welding saddle branches to polyethylene pipes of gas pipelines at ambient temperatures up to minus 50 C based on thermal process control by introducing preheating into the technological process with subsequent cooling to equalize the temperature and cool the joint under a layer of thermal insulation material of calculated thickness.
Methods and objects of research: in the first part of the work, the object of study is the non-stationary thermal process of welding. The mathematical model of the thermal process takes into account the heat of the phase transformation of polyethylene in the temperature range, the dependence of thermophysical characteristics on temperature and the degree of crystallinity of the material.
Main results of research: calculations have determined the welding parameters of the saddle branch, which ensure the flow of the thermal process according to the regularity inherent in welding under conditions of permissible ambient temperature. It is expected that the control of the thermal process will make it possible to obtain a structure of the welded joint material that ensures the strength of the seam corresponding to the strength of the seam obtained by welding under conditions of acceptable temperatures.
Changes in the physical and mechanical properties of aluminum depending on the composition of the alloying elements
Authors: Snitovsky Yuri P.
Published: January 2023

Subject of research: the influence of the concentration and composition of alloying elements Mn, Ti, Cr, Y, Mo, W, V on the change in the aluminum recrystallization temperature.
Purpose of research: to find the optimal concentration of alloying additives, at which the recrystallization temperature reaches its maximum value.
Methods and objects of research: using the methods of thermodynamic analysis of binary state diagrams of aluminum with alloying additives, it has been established that the nature of the change in the recrystallization temperature depends on what type of eutectic or peritectic reaction the formation of intermetallic compounds belongs to. It is shown that aluminides act as alloy modifiers and impart high mechanical properties to products.
Main results of research: it was found that for the AlMn system, the optimal content of Mn should be considered 0.2%, for the AlCr system, the maximum increase in the Al recrystallization temperature is observed at 0.6% Cr, for the AlY system, the mechanical properties of Al at elevated temperatures maximum at 1% Y.

Authors: Vladimirov Leonid V.
Published: January 2023

Subject of research: single-phase earth faults in electrical networks of medium voltage class.
Purpose of resarch: the development of a simulation model for the analysis of transient processes that occur during a "metallic" single-phase earth fault in a 35 kV electrical network.
Object of research: distribution electrical networks 6-35 kV operating in isolated neutral mode.
Main results of research: a simulation model was developed in the Matlab Simulink environment, which makes it possible to analyze the oscillograms of currents and voltages during a single-phase earth fault in networks with an isolated neutral. A method for determining the outgoing line with an earth fault is presented, based on the superimposition of non-power frequency currents. The source frequency is determined based on the condition for the occurrence of a resonant mode. Oscillograms are presented, from which it follows that the current in the damaged phase increases by more than 2 times, which makes it possible to selectively determine the damaged connection.
