Iterative Filtering PAPR Reduction Method for OFDM Modulation in Fifth-generation Cellular Networks
Authors: Merah Hocine , Merah Lahcene , Tahkoubit Khaled , Talbi Larbi 
Published: December 2023

Background & Objective:
Orthogonal Frequency Division Multiplexing (OFDM) is an
ordinarily used waveform in the fifth generation (5G) cellular networks for uplink links. However,
there is a prominent disadvantage in the form of a high peak-to-average power ratio (PAPR) which
yields distortion in the timing signal generated at the output of the high-power amplifier (HPA).

Methods:
A new method called Iterative Filtering PAPR Reduction (IFP) has been suggested in this
paper and maintains backward compatibility. The basic concept behind this algorithm is to obtain a
filter based on a constant-envelope signal that is intimate to the original signal as far as power is concerned.
The constant-envelope signal is then compared to the output between the product of the convolution
of the original signal with the filter in question, allowing for the calculation of the impulse
response of the filter. Such a process can be repeated several times with different filters to realize the
best reduction in PAPR.

Results:
The simulated results of the IFP method proved better performance in terms of PAPR reduction,
Bit Error Rate (BER), and computational complexity requiring two iterations only. We can
see a gain of 3.1dB in terms of PAPR reduction, 17dB in terms of BER, and a factor of 33 times in
terms of computational complexity compared to the TR method. The Complementary Cumulative
Complementary Density Function (CCDF) has assisted in measuring and improving the PAPR performance
of the system.

Conclusion:
The theoretical analysis shows that a single iteration (NF= 1) is sufficient, and the simulation
results exposed in this paper show a gain of 3.1 dB in PAPR reduction.

Authors: Liu Jiaxing , Gupta Shalini , Chen Aipeng , Wang Chen-Kai , Mishra Pratik , Dai Hong-Jie , Wong Zoie Shui-Yee , Jonnagaddala Jitendra 
Published: December 2023

Background
Electronic health records (EHRs) in unstructured formats are valuable sources of information for research in both the clinical and biomedical domains. However, before such records can be used for research purposes, sensitive health information (SHI) must be removed in several cases to protect patient privacy. Rule-based and machine learning–based methods have been shown to be effective in deidentification. However, very few studies investigated the combination of transformer-based language models and rules.

Objective
The objective of this study is to develop a hybrid deidentification pipeline for Australian EHR text notes using rules and transformers. The study also aims to investigate the impact of pretrained word embedding and transformer-based language models.

Methods
In this study, we present a hybrid deidentification pipeline called OpenDeID, which is developed using an Australian multicenter EHR-based corpus called OpenDeID Corpus. The OpenDeID corpus consists of 2100 pathology reports with 38,414 SHI entities from 1833 patients. The OpenDeID pipeline incorporates a hybrid approach of associative rules, supervised deep learning, and pretrained language models.

Results
The OpenDeID achieved a best F1-score of 0.9659 by fine-tuning the Discharge Summary BioBERT model and incorporating various preprocessing and postprocessing rules. The OpenDeID pipeline has been deployed at a large tertiary teaching hospital and has processed over 8000 unstructured EHR text notes in real time.

Conclusions
The OpenDeID pipeline is a hybrid deidentification pipeline to deidentify SHI entities in unstructured EHR text notes. The pipeline has been evaluated on a large multicenter corpus. External validation will be undertaken as part of our future work to evaluate the effectiveness of the OpenDeID pipeline.
Evaluating the Impact of an App-Delivered Mindfulness Meditation Program to Reduce Stress and Anxiety During Pregnancy: Pilot Longitudinal Study
Authors: Balsam Donna , Bounds Dawn T , Rahmani Amir M , Nyamathi Adeline 
Published: December 2023

Background
Stress and anxiety during pregnancy are extremely prevalent and are associated with numerous poor outcomes, among the most serious of which are increased rates of preterm birth and low birth weight infants. Research supports that while in-person mindfulness training is effective in reducing pregnancy stress and anxiety, there are barriers limiting accessibility.

Objective
The aim of this paper is to determine if mindfulness meditation training with the Headspace app is effective for stress and anxiety reduction during pregnancy.

Methods
A longitudinal, single-arm trial was implemented with 20 pregnant women who were instructed to practice meditation via the Headspace app twice per day during the month-long trial. Validated scales were used to measure participant’s levels of stress and anxiety pre- and postintervention. Physiological measures reflective of stress (heart rate variability and sleep) were collected via the Oura Ring.

Results
Statistically significant reductions were found in self-reported levels of stress (P=.005), anxiety (P=.01), and pregnancy anxiety (P<.0001). Hierarchical linear modeling revealed a statistically significant reduction in the physiological data reflective of stress in 1 of 6 heart rate variability metrics, the low-frequency power band, which decreased by 13% (P=.006). A total of 65% of study participants (n=13) reported their sleep improved during the trial, and 95% (n=19) stated that learning mindfulness helped with other aspects of their lives. Participant retention was 100%, with 65% of participants (n=13) completing about two-thirds of the intervention, and 50% of participants (n=10) completing ≥95%.

Conclusions
This study found evidence to support the Headspace app as an effective intervention to aid in stress and anxiety reduction during pregnancy.

The Uncanniness of Intermediality. Joanna Hogg’s Eerily Self-Reflexive Cinema
Authors: Pethő Ágnes 
Published: December 2023

Abstract
The article argues for the relevance of the concept of the uncanny for a nuanced approach of intermediality. It identifies specific areas where the uncanniness of intermediality appears and examines Joanna Hogg’s three autobiographically inspired films, The Souvenir (2019), The Souvenir Part II (2021), and The Eternal Daughter (2022) from this point of view. The analysis does not offer a psychoanalytic reading of these films but focuses on aesthetic configurations that enable the affective performativity of intermediality in conjunction with particular strategies of reflexivity, and unravels the ways in which, ultimately, all these films speak about the uncanny, mutually haunting relationship between art and life. Blurring the line between fiction and nonfiction, Hogg depicts the paradoxical nature of (post)trauma and the emotional turmoil of mourning feeding into artistic creativity. The Souvenir films revolve around the loss of a lover in her youth and weave together different styles and resonances across art history and many mediums. They reveal memory, imagination and palpable reality folding over in an uncanny and aestheticized construction of space and time. The Eternal Daughter presents a scenario of caring for her dying mother, and brings to the fore the tropes of the haunted house, ghosts and doubles, which were latent figures of the earlier films as well.1

Abusive School Leadership Practices and Teacher Dissenting Voices: Analysis through Nancy Fraser and Miranda Fricker
Authors: Khumalo Shuti Steph 
Published: December 2023

Abstract
Research notes a significant rise in varied practices of abusive supervision within the schooling context. Abusive leadership is a social justice dilemma which needs sustained confrontation. This qualitative conceptual study provides a philosophical exploration of the practices of abusive school leadership towards teachers with dissenting voices. This paper takes a conceptual methodological approach and deploys dominant social justice theories espoused by Miranda Fricker and Nancy Fraser as underpinning lenses. Extant and established scholarly literature on abusive supervision was identified and critically analysed. In its examination, the guiding research question was: what are the attributes of abusive school leadership and how do such leadership react to voices that are dissenting? This study is significant because there seem to be inadequate scholarly and empirical contributions on abusive school leadership practices towards teacher dissenting voices.
Elephant in the room: Placing of Technical and Vocational Training College students for work-integrated learning in Eastern Cape Province
Authors: Jaca Celiwe , Marongwe Newlin 
Published: December 2023

Abstract
Upon passing matric, countless students choose to study further at Technical and Vocational Training Colleges (TVETs). Nevertheless, some of these students seem to be unable to attain the qualification that they studied for as they struggle with placements for Work Integrated Learning (WIL), which is a requirement for completion of the qualification. Various research has been done investigating the importance of WIL in enhancing student employability and the acquisition of practical skills; however, few have focused on the placement of students in employment centers. This study’s objective was to investigate the challenges that the selected TVET college faces when placing students. This research study adopted a qualitative research methodology. A case study design and constructivism approach were used. Data were collected through open-ended interviews and focus groups. Purposive and snowball sampling techniques were used. The study revealed that there was an elephant in the room. The students faced challenges such as a lack of funding, personnel shortages, geographic location of the colleges, etc. that led to other challenges, as explained in the study. The study concluded that the college had various challenges in placing students for WIL, and thus they had a huge backlog. These range from inconsistency in placement, the inability to prepare and guide students before and during placement, a lack of support, and a lengthy waiting period. A number of recommendations, such as a complete overhaul of the WIL placement process, the recruitment of competent personnel, and widening the pool of funders to fast-track the process and minimize the backlog, are suggested.
Case Study in Hypothesis Prioritization with Ishikawa Diagrams
Authors: Barsalou Matthew 
Published: December 2023

Abstract
The objective of this paper is to explore a multidisciplinary problem-solving team investigating a customer-reported failure using an Ishikawa diagram with a spreadsheet for prioritizing and tracking investigation actions in a manufacturing organization. A case study methodology is used with the actions taken to investigate a customer-reported failure explained. The highest priority failure hypothesis was found to be unrelated to the failure. Two medium-rated hypotheses were found to be causing the problem; leakage was occurring at the connection between two components due to a diameter deviation of one of the components. Identifying and prioritizing hypotheses from the Ishikawa diagram provided structure to the investigation and gave the investigation team leader a tool for tracking the investigation actions. This approach is suitable for all types of failure investigations in which an Ishikawa diagram is used to list hypotheses.
Calculation of the Operational Characteristics of the Impulse Gas-Barrier Face Seal
Authors: Kuznetsov Eduard , Pandová Iveta 
Published: December 2023

Abstract
The problem of reducing leaks along the pump or compressor shaft of pumped liquids and gases into the environment is very urgent. Serious difficulties have to be faced when sealing the shafts of machines that pump aggressive, toxic, explosive and fire-hazardous environments. According to modern occupational safety requirements, such pumps and compressors should use double seals with a barrier medium whose pressure exceeds the sealed one by 0.05-0.2 MPa. Currently, liquid-lubricated double mechanical seals are widely used in chemical production equipment, however, over the last decade of the 20th century, leading companies have developed a number of designs of double gas mechanical seals for pumps and chemical production devices, which significantly exceed liquid-lubricated seals in their performance characteristics. The vast majority of these seals use a gas-dynamic principle of operation, i.e. spiral, logarithmic, T-shaped or other micro grooves are made on the sealing faces of their rings, which, when rotated, create an additional gas dynamic force that ensures the functioning of these seals with a micron gap between the sealing pair. In this paper, the design, principle of operation and engineering methodology for calculating the main characteristics of a impulse gas barrier face seal, in which one pair of sealing rings performs the functions of a double mechanical seal, is considered. The design is simple, compact and, thanks to the more advanced principle of creating a gap between the sealing pair, is able to maintain operability in a wide range of sealing and barrier pressures. The existing experience of operating seals of this type on chemical production pumps has confirmed their high efficiency, reliability and safety.
