Information-response inequality in the small noise limit
Authors: Auconi Andrea
Published: March 2024

The invariant response was defined from a formulation of the fluctuation-response theorem in the space of probability distributions. An inequality which sets the mutual information as a limiting factor to the invariant response is here derived in the small noise limit based on Stam's isoperimetric inequality. Beyond the small noise limit, numerical violations exclude its general validity, however, a strong distribution bias is observed. Applications to the thermodynamics of feedback control and to estimation theory are discussed.

Published: March 2024

Context

Several challenges still exist to adopt the anti-müllerian hormone (AMH) as a marker of polycystic ovary morphology, as included in the recently updated international guideline. Although different evaluations of age- and assay-specific reference ranges have been published in the past few years, these studies have mainly been conducted in normo-ovulatory or infertile women.

Objective

To develop an age-specific percentile distribution of AMH in patients with polycystic ovary syndrome (PCOS) measured by 3 different assays.

Design

Retrospective cross-sectional study.

Patients

A total of 2725 women aged 20 to 40 years with PCOS diagnosis were included.

Interventions

Serum AMH measurement by the Gen II (Beckman Coulter), the picoAMH (Ansh Labs), and the Elecsys (Roche) assays.

Main outcome measures

Age-specific percentile curves for all the assays and correlations between AMH, clinical, hormonal, and ultrasound characteristics.

Results

Age-related nomograms for the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles of AMH were calculated using the Lambda-Mu-Sigma method for all the assays. AMH levels were significantly different between PCOS phenotypes. AMH levels were positively correlated to LH, LH/FSH ratio, testosterone, androstenedione, free androgen index, mean follicular number, and mean ovarian volume.

Conclusion

To our knowledge, this is the first study reporting age-specific percentile nomograms of serum AMH levels measured by the Gen II, the picoAMH, and the Elecsys assays in a large population of women with PCOS. These findings may help to interpret AMH levels in patients with PCOS and facilitate the use of AMH as a diagnostic tool across age ranges.

Published: March 2024

Context

Metabolic surgery remains the most effective and durable treatment for severe obesity and related metabolic diseases.

Objective

We examined cardiometabolic improvements after metabolic surgery and associated presurgery demographic and clinical factors in a large multiracial cohort.

Methods

Included were 7804 patients (20-79 years) undergoing first-time metabolic surgery at Vanderbilt University Medical Center from 1999 to 2022. Pre- and 1-year postsurgery cardiometabolic profiles were extracted from medical records, including body mass index (BMI), blood pressure, blood lipids, glucose, and hemoglobin A1c. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk was estimated per American College of Cardiology/American Heart Association equations. Pre- to postsurgery cardiometabolic profiles were compared by paired t-test, and associated factors were identified by multivariable linear and logistic regression.

Results

Among 7804 patients, most were women and White, while 1618 were men and 1271 were Black; median age and BMI were 45 years [interquartile range (IQR): 37-53] and 46.4 kg/m2 (IQR: 42.1-52.4). At 1-year postsurgery, patients showed significant decreases in systolic blood pressure (10.5 [95% confidence interval: 10.1, 10.9] mmHg), total cholesterol (13.5 [10.3, 16.7] mg/dL), glucose (13.6 [12.9, 14.4] mg/dL), hemoglobin A1c (1.13% [1.06, 1.20]), and 10-year ASCVD risk (absolute reduction: 1.58% [1.22, 1.94]; relative reduction: 34.4% [29.4, 39.3]); all P < .0001. Older, male, or Black patients showed less reduction in 10-year ASCVD risk and lower odds of diabetes/hypertension/dyslipidemia remission than younger, female, or White patients. Patients with a history of diabetes, hypertension, dyslipidemia, or cardiovascular disease showed less cardiometabolic improvements than those without. Results were similar with or without further adjusting for weight loss and largely sustained at 2-year postsurgery.

Conclusion

Metabolic surgery results in significant cardiometabolic improvements, particularly among younger, female, or White patients and those without comorbidities.
MRI-Based Vertebral Bone Quality Score Can Predict the Imminent New Vertebral Fracture After Vertebral Augmentation
Authors: Cai Jinhui , Han Wen , Yang Tingqian , Ye Haoyi , Jiang Yang , Liu Zhifeng , Liu Qingyu
Published: March 2024

BACKGROUND AND OBJECTIVES:

The incidence of imminent new vertebral fracture (NVF) is notably high after vertebral augmentation (VA), but accurately assessing the imminent risk of NVF remains a great challenge. The aim of this study was to investigate whether the MRI-based vertebral bone quality (VBQ) score can predict the risk of imminent NVF after VA within a 2-year period.

METHODS:

A total of 135 patients age 50 years and older who suffered from painful osteoporotic vertebral compression fracture and treated with VA were enrolled in this retrospective study. Each patient's VBQ scores were calculated from T1-weighted, T2-weighted, and short tau inversion recovery sequences of preoperative lumbar MRI. The clinical factors and VBQ score were integrated to create a predictive model by using the logistic regression algorithm and visualize by nomogram. Receiver operating characteristic curve, calibration curve, and decision curve analyses were used to evaluate the predictive performance of the nomogram.

RESULTS:

The mean VBQ-T1WI and VBQ-T2WI scores of the NVF group were 4.61 ± 0.55 and 0.89 ± 0.14, respectively, which were significantly higher than those of the without NVF group (3.99 ± 0.54 and 0.79 ± 0.12, respectively, P < .001), as well as the VBQ-combined score (0.75 ± 1.30 vs −0.80 ± 1.26, P < .001), which is the combination of VBQ-T1WI and VBQ-T2WI scores. On multivariate analysis, the predictors of imminent NVF included age (odds ratio [OR] = 1.064, 95% CI = 1.009-1.122, P = .022), previous vertebral fracture (OR = 2.089, 95% CI = 0.888-4.915, P = .091), and VBQ-combined score (OR = 2.239, 95% CI = 1.529-3.279, P < .001). The nomogram achieved superior performance with an area under the receiver operating characteristic curve of 0.838 (95% CI: 0.773-0.904) in predicting the imminent NVF compared to the clinical factors or VBQ-combined score alone.

CONCLUSION:

The VBQ score obtained from lumbar MRI can be used to assess the VBQ and predict the imminent NVF after VA in patients with osteoporotic vertebral compression fracture.
Effect of Platelet-Rich Plasma Dosing for Healing after Arthroscopic Cuff Repair Compared with Surgery Alone: A Systematic Review and Meta-Analysis
Authors: NUNES BERNARDO , MARTINS RICARDO , LINHARES DANIELA , AZEVEDO LUÍS , CANADAS RAPHÄEL , GUTIERRES MANUEL
Published: March 2024

Introduction

Platelet-rich plasma (PRP) has been used for arthroscopic rotator cuff repairs (aRCR), but no studies have addressed the impact of platelet concentration. The primary aim was to evaluate whether the PRP cell concentration has an effect on tendon healing after aRCR compared with surgery alone. The secondary aim was to assess the functional and pain outcomes.

Materials and Methods

A systematic review was performed with searches in the MEDLINE (PubMed), Scopus, Web of Science, and Cochrane (Central) databases according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Metanalytic procedures were performed for randomized controlled trials (RCTs), and a subgroup analysis was used for studies with target (approximately 106 cells·μL−1) or below-target PRP cellular concentrations (app. 5 × 105 cells·μL−1) regarding the primary outcome of tendon healing.

Results

This review included 10 studies (8 RCTs) with 342 patients in the aRCR + PRP group and 344 patients with isolated aRCR. The risk of bias was low to intermediate (6/4, respectively). Meta-analysis of the RCT revealed that the aRCR + high-concentration PRP group had an approximately 3.9-fold higher chance of healing than the non-PRP group (odds ratio, 3.89; 95% confidence interval, 1.78–8.44; P = 0.0007). No significant difference in healing was found between the aRCR + low-concentration PRP and non-PRP groups (odds ratio, 2.21; 95% confidence interval, 0.66–7.45; P = 0.2). The Constant–Murley score and University of California Los Angeles scores were significantly improved in the aRCR + PRP groups with more than 12 months of follow-up, and no significant differences were found consistently for the American Shoulder and Elbow Society and visual analog scale scores.

Conclusions

This study highlights that a PRP cell concentration close to the target (106 cells·μL−1) of patients with aRCR may improve their healing and functional outcomes and that dosing may be potentially useful in therapy.

Authors: Crisafio Mary E. , Anderson Hadalyn A.L. , Thraen-Borowski Keith M. , Schmitz Kathryn H. , Leach Heather J.
Published: March 2024

Context

Given the rapid transition of many cancer-specific community-based exercise programs to videoconference-delivered online exercise (VOE) during the coronavirus disease 2019 pandemic, little is known about the reach, effectiveness, adoption, implementation, and maintenance of these programs.

Objective

The purpose of this scoping review was to synthesize practice-based information regarding VOE programs for cancer survivors in community-based settings.

Design

To identify relevant programs, searches were conducted for peer-reviewed articles published in electronic databases and programs listed in the Moving Through Cancer directory.

Eligibility Criteria

To be included, programs had to meet the following criteria: 1) participants were adult (>18 yr) cancer survivors, 2) included one or more VOE sessions in addition to any preprogram assessment/intake, and 3) defined as a community-based program with a primary focus of delivering a service to cancer survivors.

Study Selection

A total of 16 programs were included in the review.

Main Outcome Measure

Descriptions of 1) reach, 2) effectiveness, 3) adoption, 4) implementation, and 5) maintenance of the identified programs.

Results

All studies described at least one element of reach (80%), adoption (86%), and implementation (80%). Fewer programs reported on indicators of efficacy/effectiveness (25%) and individual-level maintenance (0%).

Conclusions

VOE programs may be viable for engaging cancer survivors, but more information is needed to understand VOE programs in community-based settings. Findings from this review reveal that more work is needed, particularly in the elements of reach, efficacy/effectiveness, and individual-level maintenance. Research on community-based programs should continue in order to better understand what contributes to successful implementation of VOE programs and the effects for cancer survivors.
A Study on the Production Characteristics of Ceramic-quality Pottery from Aragaya (Haman-style Pottery): Focused on Excavated Artifacts from Ugeo-ri Kiln Site V in Haman
Authors: Park Yeong A , Han Woo Rim
Published: March 2024

In this study, for the purpose of securing basic data and examining the production characteristics of pottery produced in Aragaya, 57 pieces of pottery excavated from the kiln of Haman Ugeo-ri Ⅴ and 22 pieces of kiln construction facilities were selected and compared by type and the homogeneity of the production raw materials was reviewed. As a result, most of the earthenware was made with thin walls and carefully selected clay, and smooth and dense cross-sectional structure and color change of the core were confirmed due to firing in a high-temperature environment of 1,300℃ or more. Additionally, considering the differences in chemical composition for each type, it is presumed that different raw material preparation processes were used depending on the firing degree intended by the potter. In the case of some samples that do not match the actual firing degree, it is judged to be a failure product or the result of multiple re-firing. As a result of analysis of the kiln construction section facility, mica and chlorite were detected in the weathered rock layer corresponding to the lowest layer of the combustion zone, so it appears that high temperatures were not reached in this section. On the other hand, high-temperature generated minerals such as Cristobalite and Mullite were detected in the soil of the fired section, indicating that it was fired at high temperature. Compared to the kiln-built facility, a higher viscosity composition of earthenware clay is confirmed. Therefore, it is presumed that earthenware was made using soil with higher plasticity than kiln-building facilities. In addition, since the clay content of the kiln construction facilities showed a more diverse composition range than that of earthenware, it is assumed that clay of various compositions was used when repairing the kiln.
Korean Wooden Architectural Heritages at An Increased Risk of Termite Damage due to Temperature Change
Authors: Kim Sihyun , Kim Jisoo
Published: March 2024

Wooden architectural heritages in Korea have been severely damaged by termites, and this damage is expected to increase owing to climate change. This study aimed to evaluate the changes in termite damage risk due to climate change specifically in Korean wooden architectural heritages. A multiple regression equation was developed to estimate the daily average temperature from the location information (latitude, longitude, and elevation) for 40 years (1980-2019). The location information of 106 nationally designated wooden architectural heritages distributed across 84 cities was used to estimate the daily mean temperature of each cultural heritages. Referring to a previous study on the ecological characteristics of R. speratus, a dominant termite species in Korea, the temperature at which termite activity is possible was confirmed, and the amount of wood consumed in relation to the temperature change was estimated. Based on this, the number of days available for termite activity and the amount of termite wood intake in the 1980s, 1990s, 2000s, and 2010s were estimated. Consequently, we found that the number of active days for termites increased from 243 to 249, 251, and 253 days in each decade. The wood consumption rate also increased by 9.9% over 40 years, from 6,657 to 6,777, 7,008, and 7,314 μg/ worker/year, respectively. This study was the first to estimate the activity period and wood intake of termites in Korea’s wooden architectural heritages, thereby providing valuable information for the preservation and management of these wooden heritages.
Study on the Gel Cleaning System for Removal of Poly(Vinyl Acetate) Fixative of the Mural Paintings of the Payathonzu temple in Bagan, Myanmar (Ⅱ) : Focusing on Applicability of Gel Cleaners
Authors: Yu Yeong Gyeong , Lee Hwa Soo , Han Gyu-Seong , Han Kyeong Soon
Published: March 2024

In this study, a gel cleaning experiment was conducted to stably remove the fixative (PVAc) used in the past conservation treatment of the mural painting of the Payathonzu temple. This study prepared mock-up samples reflecting the material properties and conservation status of the mural painting of the Payathonzu temple, and conducted an experiment about the applicability of 6 types of gel cleaners to discern potential changes when they are applied to the actual mural painting and to review their stability. This study found that the gel cleaner mixed with dimethyl carbonate had a superior removal effect to the gel cleaner mixed with acetone. Furthermore, for the same solvent, the gelling agent showed the removal effect in the order of Nevek® > Carbopol®980 > Laponite®RD. Upon examining change patterns after applying the cleaners, this study found that the cleaners with a superior removal power had a similar trend to that in removal effect evaluation in a previous study. In actually applying to the mural painting, however, the cleaners showed some inconsistent results with those in removal power evaluation, and it was confirmed that these results were attributable to the properties of the cleaners interacting with the properties of the mural painting and the extent of penetration of the fixative. It was also found that not only the conditions of the cleaners but also the material and painting technique characteristics of the mural could have a huge effect during the removal of the fixative. What is most important in removing the fixative applied to the mural painting of the Payathonzu temple is to ensure the stability of its painting layer by using a cleaning method that is controllable by the person treating the painting, and then, the properties that can help to effectively remove the fixative are required. At a time whenthere are few related studies in Korea, this study and its method may serve as a reference for future research on the removal of the fixative applied to a mural.
Material Characteristics of Lime Plaster in Goguryeo Mural Tombs (I): Focusing on Lime Plaster Excavated from Anak Tomb No.3
Authors: Lee Kyeongmin , Han Kyeong Soon
Published: March 2024

Physical and chemical investigations were conducted on lime sample from Anak Tomb No.3 to determine the properties of the plaster material. The morphological and physical characteristics of the specimens were analyzed using both a microscope and a polarizing microscope. The constituent materials were identified through X-ray diffraction and scanning electron microscope-energy dispersive spectrometer, and the qualities of the mixed material were established through thermal analysis. Additionally, micro-computed tomography was used to non-destructively confirm the internal structure and density characteristics. The lime sample was recognized as a lime plaster material with two unique layers. Each layer shows variations in material properties. It is speculated that this lime specimen was used to finish the edges of the authentic wall within Anak Tomb No.3. Through the synthesis of various morphological attributes and physical properties; the whiteness, durability, thinness, and repetition of the layers, as well as smoothness of the lime plaster used for Anak Tomb No. 3 indicate that a high level of lime wall plastering technique was used in Goguryeo Tomb. It was possible to evaluate the refined level of lime wall manufacturing technology in the Goguryeo era.

Published: March 2024

This study conducted a cross-sectional analysis of 10 beads and a surface analysis of 38 beads among 48 glass beads excavated from the Naedeok-ri site in the Gimhae region, Korea. According to the cross-sectional analysis results, all glass beads were cobalt blue, and depending on the period, the bead colors from wooden coffin tomb No. 19 from the Proto-Three Kingdoms period and wooden coffin tomb No. 92 from the Three Kingdoms period were determined to be ultramarine and Wedgewood blue. According to the surface analysis results, the colors of the beads were divided into blue from the Proto-Three Kingdoms and Three Kingdoms eras, and brown from the Joseon Dynasty. Furthermore, the size of the beads was estimated to be Gimhae “small-sized”. These small beads were popular until the late Gaya period. As a result of analyzing the composition of the glass, only potash 1 type was confirmed in the cross section, but lead, potash, and soda glass were confirmed in the surface analysis. This is because glass from the Proto-Three Kingdoms period was easily broken, and glass from the Three Kingdoms period was excavated relatively complete. Through this study, Gimhae Naedeok-ri is confirmed to be a group that uses glass with various ingredients. These results reveal a trend moving in the following order: lead-barium Ⅱ → potash Ⅰ⋅Ⅱ → soda alumina → potash Ⅲ⋅lead glass.

Published: March 2024

This paper was written after the beginning of the 2022 energy and security crisis in Europe, which forced the national state governments as well as the European Union (EU) to reexamine environmental and energy strategies. The paper focuses on the role that small modular reactors (SMRs) may play as a part of a medium and long-term solution to this unprecedented situation. The history of EU climate policies and the current energy situation in the EU is broadly examined. The paper explores the potential energy, national security, and environmental benefits of nuclear power, along with its possible contribution to a net-zero economy. The main focus of the study, involving discussions with experts in the United States (US), was on the development of SMR-specific regulations, as well as the progress of SMR deployment projects in the US. The discussion explores SMR deployment challenges and potential solutions, in terms of policy recommendations applicable for the EU and its member states, in case a rapid SMR deployment becomes politically desirable.

Published: March 2024

In this study, the zooplankton distribution and composition of Işıklı Lake, located in the Inner West Anatolia region of Türkiye, were examined monthly between 2003-2005. Zooplankton samples were collected with Hydro-Bios plankton net (55 µm) at the surface and fixed in formaldehyde (4 %). Physiological parameters such as surface water temperature, pH, dissolved oxygen, and conductivity were also measured. Also, the frequency index (F %) and the Brachionus / Trichocerca (QB/T) were determined to assess the trophic composition of Lake Işıklı. A total of 49 species have been identified. Rotifera (55 %), Cladocera (27 %) and Copepoda (18%) were represented by the species. The maximum species was found in May 2004 (21 species), while the minimum was found in October 2003 (5 species). Asplanchna priodonta, Keratella cochlearis, Keratella tecta, Polyarthra dolichoptera, Synchaeta pectinata, Bosmina longirostris and Chydorus sphaericus are common species in the lake. The water temperature varied between 3.9-24.6 °C; pH ranged from 8.1 to 8.8; the electrical conductivity ranged from 341 µS/cm to 434 µS/cm; the dissolved oxygen values changed from 5.8 mg/L to 11.1 mg/L. According to the frequency index (F %), the most dominant species are B. longirostris (74 %), K. cochlearis (62 %), A. priodonta (54 %), and C. sphaericus (51 %). A total of 20 species are reported for the first time from the region. Newly reported species from the lake were: the rotifers, A. priodonta, Brachionus angularis, Brachionus calyciflorus, Colurella colurus, Keratella quadrata, Lecane clostrocerca, Lecane ludwigi, Lecane luna, Lecane lunaris, Lecane ohioensis, Lecane quadridentata, Lecane sp., Mytilina mucronata, Notholca acuminata, Notholca squamula, Trichotria tetractis, the cladocerans Acroperus harpae, Daphnia cucullata, and the copepods Eucyclops macrurus and Megacyclops gigas. Considering the Brachionus / Trichocerca (QB/T) ratio according to the Sládeček (1983) index, the lake showed mesotrophic features.

With favorable environmental conditions and the adoption of new technologies, Türkiye has 1703 enterprises producing trout as of 2022. These enterprises collectively produce 167,286 tons of trout per year, including portioned fish (200-250 g), fillet candidates (400-600 g), and fillets (known as Turkish Salmon) (>3000 g). The production chain for Turkish Salmon involves hatcheries, dam lake net cage systems, and offshore net cage systems. There are 680 hatcheries producing trout eggs and fry, with a total annual production of 1,360,029,485 eggs. Additionally, 622 pond/dam lake net cage systems are used for producing Turkish Salmon candidates weighing 400-600 g, with a total production capacity of 163,525,079 kg per year. Offshore net cage systems in the Black Sea region, spread across six provinces, are utilized for Turkish Salmon production. Production planning is underway for two provinces, with a total planned production area of 15,650,000 m2 and a projected capacity of 221,188,000 kg per year. Türkiye is actively involved in the global aquaculture sector, paying close attention to its advancements. Türkiye has a strong egg/juvenile production capacity compared to other countries involved in trout production globally. However, the importation of biotechnology-applied and observed eggs continues, posing biological and genetic risks to Türkiye's natural aquatic areas. Over the past 20 years, Türkiye's trout production has grown significantly, reaching 167,286 tons per year, marking it as a significant food production industry. This success can be attributed to favorable environmental conditions, increasing consumer demand, the adoption of new technologies, and consistent investments. However, the rapid growth in the trout farming sector over the past five years has led to an uncontrollable decline in survival rates. This decline can be attributed to the spread of diseases, incorrect treatment methods, improper breeding management practices, flawed business management, unregulated fish transport, and compromised sanitary and environmental conditions.
PROCEDIMIENTOS Y CONCEPTOS ESCULTÓRICOS EN LA PRODUCCIÓN CERÁMICA DE PICASSO, EN VALLAURIS, EN 1947 A 1962.
Authors: Luque Teruel Andrés , Iglesias Cumplido Alicia
Published: March 2024

El artículo plantea el estudio del subgrupo de la producción cerámica de Picasso que responde a criterios propios de la escultura, esto es, a la que está resuelta con criterios plásticos y tiene propiedades volumétricas con independencia de su ejecución con medios propios de los alfares. Eso implica el reconocimiento de seis procedimientos distintos, responsables de las derivaciones técnicas y formales con las que Picasso trascendió el género para modelar auténticas esculturas. El reconocimiento de esa creatividad técnica, hasta ahora sin estudiar en la cerámica escultórica de Picasso, aporta un nuevo modo de verlas, suficiente para su futura inclusión en sus catálogos de escultura, en los que por ahora sólo están integradas algunas de las obras aquí analizadas, por lo general aquéllas en las que el procedimiento artesanal previo es menos evidente y se impone la realidad visual de las formas.

Published: March 2024

El registro de la Primera Edad del Hierro en el bajo valle del Ebro presenta un panorama especialmente óptimo para el estudio arqueológico de los rituales de comensalidad. El abandono súbito de múltiples asentamientos por motivo de incendio y la documentación in situ de los repertorios permite disponer de una información especialmente detallada sobre la lógica funcional de los conjuntos y sobre el uso social de los espacios. Además, la identificación de determinados núcleos diferenciales que habrían desempeñado un rol destacado en sus respectivas microrregiones permite avanzar notablemente en la caracterización de las políticas de comensalidad y en el conocimiento de los ritmos y procesos de cambio social que acontecieron en este territorio

This paper discusses the archaeological research and historical contextualisation of the Alto da Raia enclosure located on the border between northern Portugal and Galicia, identified as a possible Roman camp, following an interdisciplinary and multi-proxy approach. This included archaeological excavation, remote sensing and geophysical survey, as well as sample collection for archaeobotanical and geochemical studies by means of chemical and mineralogical analyses and absolute dating using radiocarbon and luminescence protocols. The results seem to indicate that this site was a Roman camp probably built and occupied between the 1st century BC and the 1st century AD, when major changes occurred in Northwest Iberia driven by the expansion of the Roman State. The camp overlaps with previous prehistoric occupations possibly dating back to the Bronze Age and Iron Age.

Published: March 2024

Translating a children's picture book is a challenging process. The focus of translating children's picture books is not only to transfer the meaning into the target language but also to guide the children to quickly understand the meaning of the sentences. Therefore, the translator must apply the appropriate sentence translation technique. This study aims to describe translation techniques used in translating Indonesian children's picture books into English. The data of this study are sentences taken from the Indonesian picture book "The Sacred Crocodile." The researchers used purposive sampling and a comparative method to analyze the data. The finding shows that translators use five translation techniques by Vinay and Darbelnet (1995) in translating sentences: literal translation, modulation, transposition, and equivalence. The literal translation is the most frequently used translation technique, followed by transposition. The literal translation is a technique by which the translator translates expressions word-for-word from SL into TL. The dominant use of literal translation indicates that the translator tried to make the sentences easily understood by children. For further study, the researcher may consider the psychological aspects and characteristics of the children in order to motivate the children to read an English story book.
Role-reversal and discussion-oriented models for flipping digital vocabulary achievement in English classrooms for Electronic Engineering learners
Authors: Sutrisno Djoko , Annury Muhammad Nafi
Published: March 2024

This research aims to verify whether two classroom models, discussion-oriented and role-reversal, have an effective strategy for teaching vocabulary achievement to English language learners. The proposed models were examined as a successful method for teaching and learning vocabulary. A quasi-experimental strategy was used with three intact classes: one control (Electronic Engineering Learners A class) and two experimental (B and C class) (Electronic Engineering Learners B and C class). Using pre- and post-test writings, the effectiveness of the two models, which incorporated two digital applications, was determined. Additionally, a questionnaire created by the researcher and a semi- structured interview was used to assess vocabulary achievement. Covariance analysis revealed that classrooms that emphasized discussion and role reversal were more effective than those that did not. In terms of vocabulary growth in post-test expository writing, the role-reversal group also outperformed the discussion-oriented group. Further analyses revealed the positive perceptions and experiences surrounding flipped classrooms, highlighting four themes: instructor support, personal sentiment, peer support, and activities beyond the classroom. This report concludes by emphasizing the need for further research into this potential technology-based pedagogy across diverse language skills and the incorporation of technology in Vocabulary Achievement.
Introducing artificial intelligence (AI)-based digital writing assistants for teachers in writing scientific articles
Authors: Khabib Samsul
Published: March 2024

Artificial intelligence (AI) technologies have played essential roles in the development of teachers. In recent years, AI-based digital writing assistants have received increasing attention among teachers. Thus, this study aims to know the use of AI-based digital writing assistants to help teachers write scientific articles. It used a sequential explanatory mixed methods study to gain the research data. Descriptive analysis was completed for the quantitative data, and thematic analysis was used for the qualitative data. The instrument used was surveys, consisting of pre and post-survey. Interestingly, the pre-survey found that teachers are not very familiar with digital writing assistants. Some of the participants had no prior knowledge of AI-assisted writing tools, while others only had limited experience. This means that more people need to be aware of the potential that AI offers in facilitating scientific writing. Furthermore, it is essential to teach teachers how to use this technology, as it can help them save time and effort while they write their articles. The post-survey conducted at the end of the project found that teachers found the process of writing a scientific article to be easier and more enjoyable with the help of AI. The results suggest that AI-based digital writing assistants may be able to provide an alternative method for teachers to compose their scientific articles. This tool could help to reduce errors and enable more efficient writing with greater accuracy. Additionally, the feedback suggests that AI-based tools could aid in improving students’ engagement and interest in writing.

Authors: Ekinci Mithat , Kırkgöz Yasemin
Published: March 2024

With the changing world and the developing technology, many alterations occur throughout the world as a whole. Managing and directing an educational institution is not an exception. The teaching and learning process, as well as the place of stakeholders of these educational institutions, are currently in a period of development as the governments are concerned with raising the standards of education. All these changes and standardization movements put pressure on the administrators, especially on those new to such positions. The situation becomes even worse when these administrators lack the necessary experience and training. To draw attention to these issues, this case study aimed to elicit the opinions of a novice administrator concerning leadership and administration practices and identify the critical challenges she faced during the first year of her appointment. A qualitative case study research methodology was employed in the present research. Two different data collection tools were used: a semi-structured interview with the participant administrator and a diary of the participant. Content analysis was used to analyze the obtained data. The results of the study demonstrated that working as a novice administrator is a gratifying task, yet, it creates personal, occupational and relational challenges for the administrator.

Gingival recession. Part 1: prevalence and aetiology
Authors: Hudson Joshua , Darbar Ulpee
Published: March 2024

Gingival recession affects more than half of the population and has a multifactorial aetiology. Despite this, the knowledge and awareness of the factors that predispose sites to recession remains limited, with most people associating it with poor oral hygiene. As patients retain their teeth for longer, the risk of recession is likely to grow, thus increasing the need to establish a greater understanding of this very common condition. This two-part series provides a contemporary overview of the condition with the first article discussing its prevalence, aetiology and classification, and the second covering the different management options.

CPD/Clinical Relevance: It is important to establish the aetiology of gingival recession to manage the condition effectively.

Multi-frame demosaicing for the Quad Bayer CFA in the color difference domain
Authors: Kim Hansol , Park JongEun , Gi Kang Moon
Published: March 2024

Recently, imaging systems with submicron image sensors have been increasingly adopting the Quad Bayer color filter array (CFA) owing to its high sensitivity under low illumination conditions when pixel binning techniques are employed. Conversely, under sufficient illumination conditions, direct demosaicing methods are required for the Quad Bayer color filter array to obtain a full-resolution color image. However, the Quad Bayer color filter array is more susceptible to aliasing artifacts because of its structural disadvantages compared to the Bayer color filter array. In this paper, we propose the multi-frame demosaicing method to address this problem. The proposed method assesses local spatial contributions within local windows at each pixel to reconstruct the lost spatial resolution caused by aliasing. Additionally, we utilize the color difference domain to exploit inter-channel correlations, aiming to alleviate color artifacts and enhance spatial resolution. The experimental results demonstrate that our proposed method outperforms other methods, both quantitatively and qualitatively, including single-frame-based demosaicing methods and another multi-frame demosaicing method with pixel binning techniques.
Low-coupling reflective metasurfaces for accurate near-field focusing
Authors: Qiao Hui , Zhuge Xiaodong
Published: March 2024

Metasurface is a 2D metamaterial which manipulates electromagnetic wavefront by carefully designing the transmissive or reflective responses of the planar subwavelength structures. Despite various emerging new functionalities, one of the limitations of metasurfaces in practical applications is the lack of control accuracy of its local amplitude and phase responses. This is in part caused by the discrepancy between the periodic EM simulated responses of unit cells and the actual non-periodic metasurfaces when functionality-determined amplitude and phase gradients are introduced. Under such conditions, the focusing capabilities of metasurfaces can be greatly affected. In this paper, we address this problem by introducing a slotted ground plane metasurface design which reduces the above-mentioned discrepancy by limiting the mutual coupling effects of a unit cell with its surrounding elements. An offset-fed near-field focusing reflective metasurface is designed and fabricated to verify the performance of the proposed design. Both the EM simulated and measurement results demonstrate the advantages of the proposed design in terms of sidelobe level and transfer efficiency.

Published: March 2024

We report femtosecond pulse generation at GHz repetition rates with the Yb:YLF gain medium for the first time. A simple, low-cost, and compact architecture is implemented for the potential usage of the system as a low-noise timing jitter source. The system is pumped by 250 mW, 960 nm single-mode diodes from both sides. The semiconductor saturable absorber mirror (SESAM) mode-locked laser is self-starting and generates transform-limited 210 fs long pulses near 1050 nm. The laser's average output power is 40 mW, corresponding to a pulse energy of 36 pJ at 1.1 GHz repetition rate. The measured laser relative intensity noise (RIN) from 1 Hz to 1 MHz is 0.42%. The performance obtained in this initial work is limited by the specifications of the available optics and could be improved significantly by employing custom-designed optical elements.
Energy-efficient regeneration routing in satellite optical networks under translucent optical payload architectures
Authors: Liu Yu , Li Xin , Li Daixuan , Huang Shanguo
Published: March 2024

The translucent optical payload architecture is most economical and feasible for optical switching in the satellite optical network (SON) using laser inter-satellite links (LISLs), where the wavelength division multiplexing (WDM) technology enables lightpaths to transparently pass through relay satellites, minimizing on-board processing. For the long-distance lightpath in SONs, lightpath regeneration is necessary to ensure the acceptable quality of transmission (QoT), where optical-electrical-optical (OEO) conversion causes non-negligible energy consumption. The rechargeable battery is an important component for low-earth-orbit (LEO) satellites, and unrestrained use batteries at a deep depth of discharge (DOD) will accelerate battery aging and shorten satellite lifetime, causing extremely high expenditure costs. How to improve energy efficiency in lightpath regeneration is a key problem in SONs, which has no related studies. This paper proposes energy-efficient regeneration routing (EE-RR) in SONs under translucent optical payload architectures, which is to reduce the battery life consumption of lightpath regeneration. We define the maximum bypass hops (MBH) to ensure the bit error rate (BER) requirement of lightpaths in SONs, considering the noise accumulation of amplifier spontaneous emission (ASE) and Doppler shift (DS) crosstalk. Two greedy baselines are proposed for EE-RR, which are the regeneration routing scheme minimizing the number of regeneration nodes (RRS-MRN) and the regeneration routing scheme minimizing single satellite’s battery life consumption (RRS-MBL), respectively. Based on two greedy baselines, the regeneration routing scheme using genetic algorithms (RRSGA) is developed to improve the optimization ability of EE-RR. To our knowledge, this is the first study to propose taking battery aging into account in lightpath regeneration in SONs. Through numerical simulation, we find that blindly reducing the number of regeneration nodes in lightpaths may not reduce overall battery life consumption, and RRSGA can effectively reduce battery life consumption of lightpath regeneration in SONs.
Pulse pattern manipulation of dichromatic soliton complexes by a twistable tapered-fiber filter
Authors: Liu Bowen , Yamashita Shinji , Set Sze Yun
Published: March 2024

Soliton complexes highlight the particle-like dynamics of dissipative pulses. However, simple and reliable manipulation of bound solitons remains challenging, particularly for all-polarization-maintaining (PM) configurations that are free from random polarization perturbations. Here, we report controllable pulse patterns of robustly coexisting dichromatic soliton complexes in an all-PM fiber laser based on a twistable tapered-fiber filter. According to the twist angle, dichromatic pulses are switched between different patterns, and components at each wavelength can be independently manipulated, extending encodings from the time to the frequency domain. To the best of our knowledge, it is the first experimental demonstration of dual-wavelength soliton complexes that different pulse patterns coexist at separated wavebands.

We describe an electrically tunable liquid crystal lens that can dynamically generate symmetric wavefront profiles. The curvature of these profiles may be inversed, enabling a bipolar response (focusing and defocusing). Different wavefronts, including non-monotonic, are predicted theoretically and demonstrated experimentally. The optical performance of the devices is characterized experimentally in an imaging scheme.
