Impact of Chamber/Annealing Temperature on the Endurance Characteristic of Zr:HfO2 Ferroelectric Capacitor

The endurance characteristic of Zr-doped HfO2 (HZO)-based metal–ferroelectric–metal (MFM) capacitors fabricated under various deposition/annealing temperatures in the atomic layer deposition (ALD) process was investigated. The chamber temperature in the ALD process was set to 120 °C, 200 °C, or 250 °C, and the annealing temperature was set to 400 °C, 500 °C, 600 °C, or 700 °C. For the given annealing temperature of 700 °C, the remnant polarization (2Pr) was 17.21 µC/cm2, 26.37 µC/cm2, and 31.8 µC/cm2 at the chamber temperatures of 120 °C, 200 °C, and 250 °C, respectively. For the given/identical annealing temperature, the largest remnant polarization (Pr) was achieved when using the chamber temperature of 250 °C. At a higher annealing temperature, the grain size in the HZO layer becomes smaller, and thereby, it enables to boost up Pr. It was observed that the endurance characteristics for the capacitors fabricated under various annealing/chamber temperatures were quite different. The different endurance characteristics are due to the oxygen and oxygen vacancies in ferroelectric films, which affects the wakeup/fatigue behaviors. However, in common, all the capacitors showed no breakdown for an externally applied pulse (up to 108 cycles of the pulse).
Determination of Quality Parameters in Mangetout (Pisum sativum L. ssp. arvense) by Using Vis/Near-Infrared Reflectance Spectroscopy

Pisum sativum L. ssp. arvense, is colloquially called tirabeque or mangetout because it is eaten whole; its pods are recognized as a delicatessen in cooking due to its crunch on the palate and high sweetness. Furthermore, this legume is an important source of protein and antioxidant compounds. Quality control in this species requires the analysis of a large number of samples using costly and laborious conventional methods. For this reason, a non-chemical and rapid technique as near-infrared reflectance spectroscopy (NIRS) was explored to determine its physicochemical quality (color, firmness, total soluble solids, pH, total polyphenols, ascorbic acid and protein content). Pod samples from different cultivars and grown under different fertigation treatments were added to the NIRS analysis to increase spectral and chemical variability in the calibration set. Modified partial least squares regression was used for obtaining the calibration models of these parameters. The coefficients of determination in the external validation ranged from 0.50 to 0.88. The RPD (standard deviation to standard error of prediction ratio) and RER (standard deviation to range) were variable for quality parameters and showed values that were characteristic of equations suitable for quantitative prediction and screening purposes, except for the total soluble solid calibration model.
Highly Elastic Melamine Graphene/MWNT Hybrid Sponge for Sensor Applications

The rapidly increased interest in multifunctional nanoelectronic devices, such as wearable monitors, smart robots, and electronic skin, motivated many researchers toward the development of several kinds of sensors in recent years. Flexibility, stability, sensitivity, and low cost are the most important demands for exploiting stretchable or compressible strain sensors. This article describes the formation and characteristics of a flexible, low-cost strain sensor by combining a commercial melamine sponge and a graphene/carbon nanotubes hybrid. The composite that emerged by doping the highly elastic melamine sponge with a highly conductive graphene/carbon nanotubes hybrid showed excellent piezoresistive behavior, with low resistivity of 22 kΩ m. Its function as a piezoresistive material exhibited a high sensitivity of 0.050 kPa−1 that combined with a wide detection area ranging between 0 to 50 kPa.
Oviductal Oxygen Homeostasis in Patients with Uterine Myoma: Correlation between Hypoxia and Telocytes

Oxygen balance is crucial for angiogenesis, immunity, and tissue repair. The human oviduct is essential for reproductive function, and any imbalance in homeostasis leads to fertility disturbances and might be a reason for ectopic pregnancy development. Uterine myoma is a widespread benign tumour, which is often accompanied by infertility. Telocytes have been discussed in the contexts of motility, fibrosis development, and angiogenesis. We observed the oviducts from patients with and without uterine myoma, comparing the expression of HIF-1, HO, VEGF and its receptor, NOS, oestrogen, and progesterone receptors by immunolabeling. The myometrial and oviductal telocytes were also compared in both groups. Biochemical analyses were conducted for FSH, LH, AMH, sFlt, oestrogen, and progesterone in blood samples. Patients with uterine myoma have different expressions of sex steroid receptors and an increased number of telocytes. The decreasing VEFG expression was compensated by the rise in the HIF-1 and NOS expression. Blood biochemical analyses revealed a higher progesterone level and lower AMH in patients with uterine myoma. No differences in sFlt, FSH, and LF were observed. Uterine myoma impacts oviduct oxygen homeostasis and might cause fertility disturbances (uterine and oviductal infertility factors).
Dance Movement Psychotherapy in Breast Cancer: “Throwing the Βall to Μount Olympus”

The present study is a Dance Movement Psychotherapy (DMP) pilot intervention designed to address the psychological challenges faced by Greek breast cancer patients, after surgery and around radiotherapy treatment. It was designed as a 12 weeks’ project, involving patients of diverse age and educational level, mostly living in rural areas. The personality and psychopathology inventory Symptoms’ Check List-90 (SCL-90), the therapist’s records and video self-observation were used in a mixed method approach. Thirteen subjects initiated the study, but they were gradually reduced and only four completed it. Statistical analysis was performed using SPSS-25 addressing this fact. Positive results of qualitative interpretation of the therapist’s data and SCL-90, as well as changes in movement patterns and self-perception evaluated via video self-observation, showed that the intervention was beneficial for the patients who completed it. However, the fact that not all the participants were able to finish the program, implies that although DMT intervention at an early stage can help some patients deal with strong emotions, careful evaluation of eligible individuals should precede. Besides the patients’ medical condition, demographic and personality characteristics should be considered in the design of future similar studies.
Potential prognostic value of the lymph node ratio and its correlation with circulating sex hormone concentration in pathological T1/2 breast cancer patients: a retrospective study

Background The lymph node ratio (LNR) is an additional informative factor complementing anatomic TNM staging in breast cancer patients. The aim of this study was to evaluate the role of LNR in the cancer-specific and overall survival (OS) in a cohort of pT1/2 breast cancer patients and examine its correlation with circulating sex hormone concentrations in postmenopausal cases of the cohort from eastern China islands. Methods Clinical and pathological characteristics, preoperational sex hormone and tumor markers concentrations, and breast cancer-specific survival (BCSS) and OS were analyzed retrospectively in 732 pathological T1/2 breast cancer patients. Results The LNR was calculated, and the cut-off value was defined as 0.042 by receiver operative characteristic (ROC) curve according to the patient’s mortalities. Patients with LNR ≥0.042 exhibited worse BCSS and OS than others (P<0.001) in pT1/2 breast cancer. Among patients with non-triple negative breast cancer (TNBC) and TNBC subtypes, the LNR ≥0.042 group also exhibited worse BCSS and OS than the LNR <0.042 group (P=0.003, 0.001, and P=0.032, 0.001, respectively). In univariate analysis, unfavorable BCSS and OS were both related with LNR ≥0.042 (P=0.001, <0.001). However multivariate analysis demonstrated TNBC subtypes were independent predictor for BCSS and OS [hazard ratio (HR) =1.449, 95% CI: 1.097–1.914, P=0.009; HR =1.365, 95% CI: 1.093–1.705, P=0.006, respectively]. Notably, Pearson or spearman correlation analysis revealed follicle-stimulating hormone (FSH) and, luteinizing hormone (LH) levels were significantly negatively associated with the LNR (P=0.007, 0.011, respectively) in postmenopausal cases, whereas CA153, CA125 and CEA were positively correlated with it (P<0.001, <0.001, 0.001, respectively) in all cases. Conclusions Among pT1/2 breast cancer patients from eastern China islands, the LNR is a predictive prognosis factor; a higher LNR seems to correlate with a worse survival outcome both overall and in the subgroups. Strikingly, the current results reveal that serum FSH and LH level inversely associated with axillary node invasion in postmenopausal cases, whereas tumor markers directly related with it. The LNR is an informative factor complementing TNM staging.

Prevalence of Substance Use Among Students in The Faculty of Medicine and Pharmacy of Casablanca, Morocco

Introduction: Substance use is a major public health problem. Medical students are an interesting population category to study, given the particularity of the stress factors to which they are exposed, predisposing them to the use of psychoactive substances. The objective of this study is to determine the prevalence of psychoactive substance use in this category, as well as the levels of dependence and risky use, and also to define the characteristics of use and the relationship between substance use and sociodemographic characteristics. Methods: Cross-sectional study with a descriptive aim, carried out in the form of a survey using a questionnaire, among 456 medical students in Casablanca, all levels combined. Results: The most widespread psychoactive substances are tobacco: 16.6%, chicha: 15.3%, cannabis: 14.9% and alcohol: 13.1%. The highest rate of risky use was noted with tobacco use: 30%, and cannabis use: 80%. More than half of the users had a family background of use, and one third of the users were repeaters. The age of initiation, for all substances, varied between 10 and 29 years. In our study, 18.6% of the students were poly-substance users. Psychiatric background was found in 42% of users vs 17% of non-users. Conclusion: The extent of psychoactive substance use among students is considerable, and the study has made it possible to identify certain socio-demographic risk factors.
The Investigation of 1997 and 2015 El Nino Events in West Sumatera, Indonesia

The 1997, 2010, and 2015 El Nino events have been recognized worldwide as a primary factor of decreasing biomass productivity. Its effects occur at farm as well as regional scale. Yet some still think that the effect is only perceived by farmers directly. We proposed a simple method to describe that its effect at catchment scale is not negligible. For this purpose, we analysed an upstream catchment in West Sumatera that normally receives high rainfall up to 5000 mm per year. This catchment is in pristine condition due to its status as national park. We used satellite and ground monitoring systems i.e . rainfall and stream water level. Satellite data such as DEM (Digital Elevation Model) used to trace river networks is acquired from ASTER GDEM in 30 m resolution. To monitor vegetation health, we used NDVI (Normalized Difference Vegetation Index) and EVI (Enhanced Vegetation Index) on board MODIS (MODerate resolution Imaging Spectroradiometer) Terra (daytime) MOD13Q1 (250 m resolution). Catchment delineation was performed using local land use map. Time series of EVI and NDVI was processes for year 2015, comprising 23 datasets. Rainfall data from year 1980 to 2012 from 9 stations and water level at the main river were analysed. We found the trace of 1997 El Nino very clearly through rainfall anomalies at all stations. As for the 2010 event, the pattern was not consistent across all rainfall stations. The 2015 event was not imminent until late October 2015. Throughout the year, NDVI remains above 0.8. In late October, maximum NDVI dropped below 0.4. This coincides with very low water level in the stream. The same pattern was also found in two neighbouring catchments with similar land use, Kuranji and Air Dingin, and Tampo catchment. This proves that the 2015 El Nino did not only threatens farmers, but also other aspects that depend on vegetation health and stream flow. Both methods are proven to be robust and may be used as an alternative way to monitor vegetation health and the impact of global climate change for ecology and water management such as domestic water use, irrigation and flood control.
Assessment of CBCT–based synthetic CT generation accuracy for adaptive radiotherapy planning

Abstract Purpose Cone‐beam CT (CBCT)–based synthetic CT (sCT) dose calculation has the potential to make the adaptive radiotherapy (ART) pathway more efficient while removing subjectivity. This study assessed four sCT generation methods using 15 head‐and‐neck rescanned ART patients. Each patient's planning CT (pCT), rescan CT (rCT), and CBCT post‐rCT was acquired with the CBCT deformably registered to the rCT (dCBCT). Methods The four methods investigated were as follows: method 1—deformably registering the pCT to the dCBCT. Method 2—assigning six mass density values to the dCBCT. Method 3—iteratively removing artifacts and correcting the dCBCT Hounsfield units (HU). Method 4—using a cycle general adversarial network machine learning model (trained with 45 paired pCT and CBCT). Treatment plans were created on the rCT and recalculated on each sCT. Planning target volume (PTV) and organ‐at‐risk (OAR) structures were contoured by clinicians on the rCT (high‐dose PTV, low‐dose PTV, spinal canal, larynx, brainstem, and parotids) to allow the assessment of dose–volume histogram statistics at clinically relevant points. Results The HU mean absolute error (MAE) and minimum dose gamma index pass rate (2%/2 mm) were calculated, and the generation time was measured for 15 patients using the rCT as the comparator. For methods 1–4 the MAE, gamma index analysis, and generation time were as follows: 59.7 HU, 100.0%, and 143 s; 164.2 HU, 95.2%, and 232 s; 75.7 HU, 99.9%, and 153 s; and 79.4 HU, 99.8%, and 112 s, respectively. Dose differences for PTVs and OARs were all <0.3 Gy except for method 2 (<0.5 Gy). Conclusion All methods were considered clinically viable. The machine learning method was found to be most suitable for clinical implementation due to its high dosimetric accuracy and short generation time. Further investigation is required for larger anatomical changes between the CBCT and pCT and for other anatomical sites.
Utility of Wavelet Denoising with Geometry Factor Weighting for Gadoxetic Acid-enhanced Hepatobiliary-phase MR Imaging

Purpose: The wavelet denoising with geometry factor weighting (g-denoising) method can reduce the image noise by adapting to spatially varying noise levels induced by parallel imaging. The aim of this study was to investigate the clinical applicability of g-denoising on hepatobiliary-phase (HBP) images with gadoxetic acid. Methods: We subjected 53 patients suspected of harboring hepatic neoplastic lesions to gadoxetic acid-enhanced HBP imaging with and without g-denoising (g+HBP and g–HBP). The matrix size was reduced for g+HBP images to avoid prolonging the scanning time. Two radiologists calculated the SNR, the portal vein-, and paraspinal muscle contrast-to-noise ratio (CNR) relative to the hepatic parenchyma (liver-to-portal vein- and liver-to-muscle CNR). Two other radiologists independently graded the sharpness of the liver edge, the visibility of intrahepatic vessels, the image noise, the homogeneity of liver parenchyma, and the overall image quality using a 5-point scale. Differences between g–HBP and g+HBP images were determined with the two-sided Wilcoxon signed-rank test. Results: The liver-to-portal- and liver-to-muscle CNR and the SNR were significantly higher on g+HBP- than g–HBP images (P < 0.01), as was the qualitative score for the image noise, homogeneity of liver parenchyma, and overall image quality (P < 0.01). Although there were no significant differences in the scores for the sharpness of the liver edge or the score assigned for the visibility of intrahepatic vessels (P = 0.05, 0.43), with g+HBP the score was lower in three patients for the sharpness of the liver edge and in six patients for the visibility of intrahepatic vessels. Conclusion: At gadoxetic acid-enhanced HBP imaging, g-denoising yielded a better image quality than conventional HBP imaging although the anatomic details may be degraded.
Marketing micro-credentials: An analysis of actors, voices and messages in educational innovation discourse

ABSTRACT Much has been written about the potential of micro-credentials to revitalise and modernise Australian higher education offerings, and to create forms of educational credit linked more meaningfully with industry. Proponents of micro-credentials speak from a range of standpoints: public education institutions, private companies, industry associations, governments, educational technology businesses and more. This review examines the neoliberal reasoning inherent in micro-credential-promoting discourse, both in Australia and globally. It shows that micro-credentials are conceived as a form of product innovation which increase the provider pool to include private companies and technology intermediaries, while students are cast as independent consumers, perpetually responsible for self-managing their own employability education, but this analysis finds student voices and perspectives are absent from the discourse.
Lean Implementation and Organizational Transformation: A Literature Review

Abstract Manufacturing organizations are constantly striving to develop more effective and flexible means for managing challenges due to globalization and increasing customer expectations. This has led to increased efforts by the business community to research and implement the Toyota Production System, or lean manufacturing, to address these challenges. These efforts have resulted in numerous publications on lean manufacturing, including research reports, scholarly articles, and trade magazine articles. However, the existing body of knowledge on lean manufacturing is disperse and diverse in nature with respect to the application and implementation of lean tools and practices, making it difficult for researchers and practitioners to gain a real grasp of this topic. In this article, we have comprehensively organized the existing work on implementation of lean manufacturing in a more structured way, enabling engineering management practitioners to more easily identify knowledge and best practices and enabling researchers to identify gaps in the extant literature. Lastly, drawing from the organizational science literature, this article also provides important insights on lean manufacturing from the perspective of organizational learning, innovation, and \culture.
SHALLOW WATERS DEPTH ESTIMATION USING EMPIRICAL SATELLITE DERIVED BATHYMETRY AND SENTINEL-2 DATA, CASE STUDY: EAST COASTAL WATERS OF JAVA ISLAND

Abstract. Hydrographic survey is an activity to provide spatial information in the marine sector. To produce accurate data, hydrographic surveys require very large costs. With the vast sea area in Indonesia, this becomes a very big challenge. In addition, there are some areas that cannot be reached by survey vessels (limited to a depth of > 25 m). Therefore, an alternative method is needed to provide bathymetry data in Indonesia. There is a new technique that is being developed and does not require high costs to obtain water depth data, by using remote sensing technology, especially by using passive sensor image technology. This technique or method is known as Satellite Derived Bathymetry (SDB) which can estimate depths of up to 30 meters. The SDB technique which is often used is empirical SDB. The empirical SDB has the principle of connecting the spectral value of the image with the measured depth. With the use of Sentinel-2 satellite imagery which has high temporal and spatial resolution, the SDB capability is expected to be improved. East coastal waters of Java Island are in the Bali Strait. This strait separates the island of Java from the island of Bali. In the Bali Strait there is a busy ferry shipping lane and there are also underwater cables used to supply electricity to Bali Island from Java Island. On the Java side, there are also many beaches and underwater tourism that must be preserved. Therefore, it is very important to be able to know the hydrographic data such as bathymetry data in the east coastal waters of Java Island. The objective of this work is thus to estimate shallow water depths using empirical SDB and Sentinel-2 images in the east coastal waters of Java Island. With two band combinations applied in the algorithm, best combination to produce the best depth map for the study area can be obtained. Comparing with reference data, the results show Band 1&3 combination give the better correlation and RMSE (0.76 and 0.026) than Band 2&3 combination (0.64 and 0.075).
