Türkiye’s Diaspora Engagement Policy: Change in Perspective Since 2010
Authors: KOLBAŞI-MUYAN Gizem 
Published: April 2023

This paper focuses on the diaspora engagement policy of Türkiye, which affects the lives of more than 6.5 million Turkish citizens and their descendants. The main research question raised in this
paper is “What has changed in the Turkish diaspora engagement policy since 2010 with the establishment of the Presidency for Turks Abroad and Related Communities (YTB)?” Following
an analysis of the diaspora engagement policy of Türkiye in the socio-economic, political-legal and socio-cultural spheres, it is concluded that since 2010, in order to maintain a connection
with the transnational diaspora, long-distance nationalism has emerged as a prominent factor. The novelty of the policy lies in its redefinition of the target groups, the features of the diaspora,
and the policy goals, actors, tools and stakeholders. Türkiye has begun to target the reintegration of post-migrant generations with Türkiye in the socio-cultural sphere through new policy
tools, and the long-distance nationalist perspective of its diaspora engagement policy has thus led to the transformation of Türkiye into a “transnational nation-state”.

Range expansion of some non-indigenous seaweeds along the coasts of Brittany – English Channel
Authors: Burel Thomas , Helias Mathieu , Le Duff Michel 
Published: April 2023

Abstract
Non-indigenous seaweed species have been introduced to the coasts of Brittany, France for decades, with an increasing arrival rate since the 1970s due to both the introduction of the Pacific oyster and increased maritime traffic. In this study, seven species of red macroalgae originating from the Pacific Ocean were found in new locations around the coasts of Brittany between 2018 and 2022. The seaweed species belong to four different orders: Ceramiales (Antithamnion hubbsii, Polysiphonia morrowii, and Symphyocladiella dendroidea), Halymeniales (including Pachymeniopsis lanceolata and Polyopes lancifolius), Rhodymeniales (Botryocladia wrightii), and Gigartinales (Solieria sp.). The dispersal mode and putative invasive potential of each species were examined, and the species were described in terms of their macroscopic and microscopic appearance and habitat. These finds result from a combination of citizen science and long-term monitoring. Used together, these two approaches can aid in the detection of these species on other European coasts and in understanding their dispersion.

Diffusion induced thermal effect and stress in layered Li(Ni0.6Mn0.2Co0.2)O2 cathode materials for button lithium-ion battery electrode plates
Authors: Xu Lipeng , Tian Chongwang , Bao Chunjiang , Zhou Fei , Zhao Jinsheng 
Published: April 2023

Abstract
This paper develops a coupling model of the relationship between chemical reaction, temperature and stress/strain for Li (Ni0.6Mn0.2Co0.2) O2 cathode materials. With the process of reaction, the concentration of electrolyte salt changes rapidly at the beginning of diffusion and tends to dynamic equilibrium. The concentration of electrolyte LiPF6 in electrode materials diffuses from bottom to top with the process of lithium intercalation. In the process of Li-ion intercalation, the temperature rise of porous electrode materials increases sharply at first, then decreases and then increases slowly. The rate of temperature rise in the cathode material increases with the temperature decreases. The volume of electrode material deformed with the expansion along the X-axis and the radial bending along the Y-axis. And the law of stress variation with time is consistent with the temperature-time curve. By the stress-strain distribution nephogram, it is found that the position where the maximum stress is located at the edge of the upper surface, and which is most vulnerable to failure.
On stochastic dynamic modeling of incidence data
Authors: Kalligeris Emmanouil-Nektarios , Karagrigoriou Alex , Parpoula Christina 
Published: April 2023

AbstractIn this paper, a Markov Regime Switching Model of Conditional Mean with covariates, is proposed and investigated for the analysis of incidence rate data. The components of the model are selected by both penalized likelihood techniques in conjunction with the Expectation Maximization algorithm, with the goal of achieving a high level of robustness regarding the modeling of dynamic behaviors of epidemiological data. In addition to statistical inference, Changepoint Detection Analysis is performed for the selection of the number of regimes, which reduces the complexity associated with Likelihood Ratio Tests. Within this framework, a three-phase procedure for modeling incidence data is proposed and tested via real and simulated data.
Implementing SRIF filter with MANS-PPP software package for GNSS precise point position solution accuracy enhancement
Authors: Shehata Ashraf G. , Zarzoura Fawzi H. , El-Mewafi Mahmoud 
Published: April 2023

Abstract
One of the primary geodetic mapping tasks in the post-processing of GNSS data is precise point positioning (PPP). Research institutions and universities have established software packages and online PPP services in prior years. Still, it is problematic to satisfy the high-rate update criterion of PPP due to the quick growth of GNSS constellations. In PPP GNSS data processing, Square Root Information Filter SRIF is not frequently handled. In this research, we used the MANS-PPP software package to execute the processing method and generate the PPP GNSS solution. The new program has been demonstrated how can effectively enhance initial time and positioning error for multi-GNSS satellites. Processing observation data with the Kalman filter and SRIF was performed using PPP in static mode for the 16 stations, and the influence of errors has been analyzed from the filtering method. The Kalman filter was unable to maintain a stable convergence curve during the PPP filtering procedure, but SRIF was successful in doing so. Based on these findings, SRIF had better numerical stability and was well-suited for settings with PPP demanding precision computing environments.
Unmanned Aircraft Systems (UAS): Applications and Integration into Hazard Mitigation Planning
Authors: Lawson Catherine T. , Rajan Karthik Soundara 
Published: April 2023

AbstractUnmanned Aircraft Systems (UAS) (also referred to as Unmanned Aerial Systems (UAS), Unmanned Autonomous Vehicles (UAVs), or drones) operations, focused on natural hazards, have experienced rapid expansion in the last decade. UAS uses before, during, and after natural hazard events, provide value for emergency management operations (e.g. Search-and-Rescue (SAR)), and post-event analytics. The Department of Homeland Security and Emergency Services (DHSES) manages UAS programs for public safety and emergency response activities in New York State. They also have the first FEMA-approved, locally adopted, web-based, interactive Hazard Mitigation Plans (HMPs). With recent advances in communication technologies (e.g. 5G), opportunities are emerging to establish a stewardship role to maximize regionwide UAS operations, including preparing for catastrophic natural hazards (e.g. earthquakes, hurricanes), leveraging existing HMPs, and incorporating new machine-learning techniques to use swarming networks before, during, and after a natural hazard event. A variety of stewardship approaches are discussed.
Getting the most out of imagery: PETTLEP and ESports
Authors: Gregg Melanie J. 
Published: April 2023

Abstract
The PETTLEP model of imagery developed by Holmes, P. S., & Collins, D. J. (2001. The PETTLEP approach to motor imagery: A functional equivalence model for sport psychologists. Journal of Applied Sport Psychology, 13, 60–83) is used to guide mental skills practitioners and researchers when designing mental imagery interventions for performance enhancement. The PETTLEP acronym represents Physical, Task, Timing, Learning, Emotion, and Perspective aspects of mental images. Using the PETTLEP model to guide imagery optimizes the effectiveness of the imagery.
Evaluation of 700 patients referred with a preliminary diagnosis of biotinidase deficiency by the national newborn metabolic screening program: a single-center experience
Authors: Erdol Sahin , Kocak Tugba Akbey , Bilgin Huseyin 
Published: April 2023

Abstract

Objectives
This study aimed to investigate the clinical, demographic and laboratory characteristics of the patients referred with a preliminary diagnosis of biotinidase deficiency through the national newborn metabolic screening program. We also attempted to determine the cut-off level of the fluorometric method used for screening biotinidase deficiency by the Ministry of Health.

Methods
A total of 700 subjects who were referred to the Pediatric Metabolism Outpatient Clinic with a preliminary diagnosis of biotinidase deficiency through the national newborn metabolic screening program were retrospectively evaluated. Patients detected by family screening were excluded. Biotinidase enzyme activity was assessed and BTD gene analysis was performed in all patients.

Results
Of 700 subjects who were referred by the screening program, 284 (40.5 %) had biotinidase deficiency (BD). The enzyme activity was 0–10, 10–30 and >30 % in 39 (5.5 %), 245 (35 %) and 416 (59.5 %) patients, respectively. The BD was partial in majority of patients (86.2 %). The cut-off level was 59.5 MRU for partial BD and 50.5 MRU for profound BD. The most common mutation detected was p.Arg157His (c.470G>A) among patients with profound BD, and p.D444H (c.1330G>C) among patients with partial BD.

Conclusions
Treatment should be initiated promptly in patients who are referred by the newborn screening program. Any mean activity under 59.5 MRU should be considered partial BD, while less than 50.5 MRU should be considered profound BD. It should be kept in mind that clinical manifestations may develop both in profound and partial BD.
Quasi-bound states in the continuum with a stable resonance wavelength in dimer dielectric metasurfaces

Abstract
Symmetry-protected bound states in the continuum (SP-BICs) are one of the most intensively studied BICs. Typically, SP-BICs must be converted into quasi-BICs (QBICs) by breaking the unit cell’s symmetry so that they can be accessed by the external excitation. The symmetry-broken usually results in a varied resonance wavelength of QBICs which are also highly sensitive to the asymmetry parameters. In this work, we demonstrate that QBICs with a stable resonance wavelength can be realized by breaking translational symmetry in an all-dielectric metasurface. The unit cell of metasurface is made of a silicon nanodisk dimer. The Q-factor of QBICs is precisely tuned by changing the interspacing of two nanodisks while their resonance wavelength is quite stable against the interspacing. We also find that such BICs show weak dependence on the shape of the nanodisk. Multiple decompositions indicate that the toroidal dipole dominates this type of QBIC. The resonance wavelengths of QBICs can be tuned only by changing either the lattice constants or the radius of nanodisk. Finally, we present experimental demonstrations on such a QBIC with a stable resonance wavelength. The highest measured Q-factor of QBICs is >3000. Our results may find promising applications in enhancing light–matter interaction.
Have European natural gas prices decoupled from crude oil prices? Evidence from TVP-VAR analysis
Authors: Szafranek Karol , Rubaszek Michał 
Published: April 2023

Abstract
Unprecedented increases in European natural gas prices observed between late 2021 and mid 2022 raise a question about the sources of these events. In this article we investigate this topic using a time-varying parameters structural vector autoregressive model for crude oil, US and European natural gas prices. This flexible framework allows us to measure how disturbances specific to the analyzed markets propagate within the system and how this propagation mechanism evolves in time. Our findings are fourfold. First, we show that oil prices are hardly affected by shocks specific to natural gas markets, whether in the US or Europe. Second, we demonstrate that oil shocks have limited impact on US natural gas prices, which points to the decoupling of both markets. Third, we evidence that over longer horizons natural gas prices in Europe are still mostly determined by oil shocks, with idiosyncratic disturbances leading to short-lived decoupling of both commodity prices. Fourth, we illustrate that along the gradual shift from oil price indexation to gas-on-gas competition, the contribution of idiosyncratic shocks to European natural gas prices has increased. Nonetheless, we discuss why the notion that EU natural gas and crude oil prices have decoupled might be premature.
Sensitivity of ultrasound scan and hysteroscopy with histopathological correlation in identifying endometrial pathology for a mixed group of symptomatic and asymptomatic patients
Authors: Shetty Ashwin , Dalal Asha , Manwani Saloni 
Published: April 2023

Background: We wished to correlate abnormal findings on hysteroscopy with abnormal findings on Ultrasound. To study the accuracy of ultrasound for detection of uterine polyps using hysteroscopy as gold standard. Analyse the cases detected with Carcinoma Endometrium and other endometrial pathology.
Methods: In this retrospective study, we summarized data from 125 patients who underwent TVS examination followed by hysteroscopy under 2 consultants from 2017 to 2020. Specimens were obtained and sent for histopathological examination. Sensitivity, specificity, positive and negative predictive values for diagnosing uterine pathology were calculated for each method.
Results: The sensitivity and specificity of ultrasonography for identifying polyps is 27.03% and 98.04% respectively The sensitivity of ultrasonography for identifying any abnormal pathology is 90.08%. A total of 74 hysteroscopy identified and histology confirmed polyps were identified with no incidence of cancer in all the polyps. A total of 8 patients were diagnosed to have Endometrial Cancer on endometrial biopsy. Of these 8, 7 were postmenopausal and 1 premenopausal. 2 patients of these were asymptomatic with incidental finding of thickened endometrium on ultrasonography.
Conclusions: Transvaginal ultrasound is a practical approach for initial evaluation of abnormal uterine bleeding, however a hysteroscopy would be necessary in most of the suspicious cases due to better diagnostic accuracy. A unique feature of this study is the inclusion of a group of asymptomatic women incidentally detected to have uterine pathology including uterine carcinoma on routine health examination hence highlighting the importance of routine gynaecological check especially in the peri and post-menopausal age group.

Published: April 2023

Background: The objective was to assess the effectiveness of circuit interval training and physiotherapy health education on anthropometric measurements and quality of life (QOL) among obese women with PCOS.
Methods: The study is a parallel group randomised controlled trial among 40 obese women diagnosed with PCOS based on Rotterdam criteria and conducted in obstetrics and gynaecology Physiotherapy centre, IGMC&RI, Puducherry. Allocation of participants to group A and group B done using permutated block randomization by an independent physiotherapist. Group A(n=20) received the conventional treatment and Group B (n=20) received the circuit interval training for 6 weeks.
Results: The outcome values obtained were calculated by the software SPSS 26. The power of the study is 80%. P<0.05 was considered a significant difference and 95% confidence. There was a significant improvement in the pre and post-test values of anthropometric measurements (BMI and WHR) within the experimental group. The minimal clinically important difference (MCID) of 1.03 points in BMI, 0.019 in WHR, and 0.018 in WHtR, which was higher than the MCID of the control group was observed between the groups. The results show that circuit interval training is effective in improving the anthropometric measurements and quality of life obesity was found to have a negative correlation with the quality of life, implying that increased weight reduces the quality of life in PCOS women.
Conclusions: Circuit interval training along with physiotherapy health education, has a positive impact on improving anthropometric measurements such as BMI, waist circumference, and metabolic parameters over time.
Perceptions and practice of breast self-examination among adult women residing in rural South Karnataka
Authors: Komal Samantha Swaroop , Venkatakrishna Srividya 
Published: April 2023

Background: Breast cancer is the most common cancer in women and is the leading cause of death among women with 40-45 years old. The only way to manage this disease is early diagnosis through screening which helps in detecting breast cancer in 90% of women that it can be treated in about 90% of women. The best accessible and affordable way to screening is breast self-examination (BSE). The main objective of the study is to assess the awareness (knowledge, attitude and practice) regarding breast self-examination among women aged 30 years and above residing in a rural area.
Methods: This cross-sectional study was conducted from June 2016 to January 2017 in villages under Ittamadu Primary Health Centre area, Ramnagara District. A total of 600 women aged 30 years or above who gave written informed consent participated in the study. A semi structured questionnaire was administered by interview method. Descriptive statistics was used for analysis.
Results: This study revealed that the awareness regarding breast cancer among adult women aged 30 years and above was 4%. Majority of the study participants had poor knowledge regarding BSE, however they had favourable attitude towards BSE. With regard to practice of BSE, only 4% of the study participants practiced BSE.
Conclusions: Breast self-examination is one of the most appropriate, convenient and cost-effective method that can be done by every woman for early detection of breast cancer and all women after the age of 18 years should be trained to do BSE correctly and regularly by healthcare workers and doctors.
Barriers and facilitators to seeking care for persons with acute brain infections: a cross sectional study
Authors: Nair Vasundharaa S. , Thomas Priya Treesa , Sekar Kasi , Netravathi M. 
Published: April 2023

Background: Acute brain infections including encephalitis are less common but serious conditions characterized by the inflammation of the brain requiring immediate accurate diagnosis and management. For many infections appropriate therapies exist, but the outcome is often less desirable because of failure to receive appropriate treatment on time due to multiple factors. The aim of the study was to understand the barriers and facilitators towards receiving care for persons with acute brain infections in a low resource setting.
Methods: The study design was cross sectional exploratory study. Consecutive patients presenting to neurology department of a tertiary referral care center for Neuropsychiatry in South India from July 2020 to September 2020 with the diagnosis of acute brain infections were assessed using the modified Kuppuswamy scale, Glasgow coma scale, the pathway scale: encounter form, patient centered health services in India and client socio-demographic and service receipt inventory.
Results: A total of 110 participants, both male and female, were recruited for the study. The average age was 39.64±16.5 years, with more female (65.45%) representation. 29% of individuals reported continued use of traditional practices while seeking care for the brain infections. Costs associated with care increased with the increase in duration of infection. There are major barriers and facilitators which either prohibit or facilitate care for persons with acute brain infections.
Conclusions: Acute brain infections continuing to be a public health challenge in developing country context, and the recognition that the delay in treatment causes significant disability, it becomes imperative to focus on the social, cultural, economic, environmental factors to understand the barriers and facilitators to health seeking among this population.
