Published: July 2022

Abstract
This study aimed to develop a low-cost experimental kit on image formation by a lens and determine its usability perception among pre-service teachers. A standard experiment kit on image formation by a lens in the secondary school syllabus uses an optical bench and a ray box set. The kit might not be available in school due to its cost. Furthermore, the experiment must be handled in a lab with teacher supervision because of electrical safety using the ray box connected to a power supply. Therefore, a low-cost with simple design experimental kit was developed with the same learning outcome as the standard kit. The research design was developmental research using the ADDIE model. The intended kit was successfully developed with an acceptable Content Validity Index of 0.92 from three experts. The usability perception was surveyed using an adapted questionnaire distributed to 26 respondents from an accessible population of pre-service teachers. All constructs of the usability perception were scored more than 4.6 over a scale of 5, indicating the kit was usable. This study implies that the low-cost kit could be implemented in schools with limited instruments in image formation by a lens while achieving the same learning outcome as the standard kit.

Published: July 2022

Abstract
The phenomenon of coastal erosion is a natural disaster that often occurs every year on the East Coast of Peninsular Malaysia. Coastal erosion can be identified through changes in coastlines found in coastal areas. Beaches in the state of Terengganu often face the problem of big waves and strong winds during the monsoon season. Coastal erosion can be identified through changes in coastlines found in coastal areas. The Ruin Monsoon phenomenon which causes tides and violent waves as high as almost four meters has eroded the land little by little over the past few decades. This study aims to determine the coastline change from 2016 until 2020 by using geospatial technology at Pantai Kuala Nerus, Terengganu. Furthermore, this study has three objectives to achieve. The first objective is to identify the coastline by using multispectral satellite imagery. The second objective is to analyze the rate of erosion and accretion along Pantai Kuala Nerus. The third objective is to determine the category of Pantai Kuala Nerus coastline according to the Malaysia National Coast Erosion Study (NCES) guidelines. The study concludes almost all erosion area in Pantai Kuala Nerus is included in critical and high erosion rate.

Q-turn: changing paradigms in quantum science
Authors: Sainz Ana Belén 
Published: July 2022

Abstract
Quantum information is a rapidly-growing interdisciplinary field at the intersection of information science, computer science, mathematics, philosophy, and quantum science. This fruitful field of research is at the core of our developments of quantum technologies, while widening the frontiers of our fundamental knowledge, and has achieved remarkable progress in the last few decades. Regardless of its scientific success, quantum information is not exempt from the intrinsic features that come from the fact that scientists are humans and members of society: both the good and the bad of our social practices leak into the scientific activity. In our scientific community, diversity and equal opportunity problems are particularly difficult to observe due to social, economic, or cultural barriers, often remaining invisible. How can our lack of awareness negatively influence the progress of science in the long term? How can our community grow into a better version of itself? This article reflects on how research events—such as conferences—can contribute to a shift in our culture. This reflection draws on what we learn from Q-turn: an initiative triggered by postdoctoral researchers to discuss these questions, and by doing so raise awareness about diversity issues and equal opportunities in quantum science. In addition to the high calibre of science, one of Q-turn’s main missions is to foster an inclusive community and highlight outstanding research that may be under-appreciated in other high-impact venues due to systemic biases. As well as a scientific programme, Q-turn features talks and discussions on issues that affect the quantum information community, ranging from diversity and inclusion, health and mental health, to workers’ rights. In this perspective article, we will consider Q-turn as an example of how a research community can work to tackle systematic biases, review the successes, and identify further points for development.
Bidirectionally connected cores in a mouse connectome: towards extracting the brain subnetworks essential for consciousness
Authors: Kitazono Jun , Aoki Yuma , Oizumi Masafumi 
Published: July 2022

AbstractWhere in the brain consciousness resides remains unclear. It has been suggested that the subnetworks supporting consciousness should be bidirectionally (recurrently) connected because both feed-forward and feedback processing are necessary for conscious experience. Accordingly, evaluating which subnetworks are bidirectionally connected and the strength of these connections would likely aid the identification of regions essential to consciousness. Here, we propose a method for hierarchically decomposing a network into cores with different strengths of bidirectional connection, as a means of revealing the structure of the complex brain network. We applied the method to a whole-brain mouse connectome. We found that cores with strong bidirectional connections consisted of regions presumably essential to consciousness (e.g. the isocortical and thalamic regions, and claustrum) and did not include regions presumably irrelevant to consciousness (e.g. cerebellum). Contrarily, we could not find such correspondence between cores and consciousness when we applied other simple methods that ignored bidirectionality. These findings suggest that our method provides a novel insight into the relation between bidirectional brain network structures and consciousness.
Steady-state responses to concurrent melodies: source distribution, top-down, and bottom-up attention

Published: July 2022

AbstractHumans can direct attentional resources to a single sound occurring simultaneously among others to extract the most behaviourally relevant information present. To investigate this cognitive phenomenon in a precise manner, we used frequency-tagging to separate neural auditory steady-state responses (ASSRs) that can be traced back to each auditory stimulus, from the neural mix elicited by multiple simultaneous sounds. Using a mixture of 2 frequency-tagged melody streams, we instructed participants to selectively attend to one stream or the other while following the development of the pitch contour. Bottom-up attention towards either stream was also manipulated with salient changes in pitch. Distributed source analyses of magnetoencephalography measurements showed that the effect of ASSR enhancement from top-down driven attention was strongest at the left frontal cortex, while that of bottom-up driven attention was dominant at the right temporal cortex. Furthermore, the degree of ASSR suppression from simultaneous stimuli varied across cortical lobes and hemisphere. The ASSR source distribution changes from temporal-dominance during single-stream perception, to proportionally more activity in the frontal and centro-parietal cortical regions when listening to simultaneous streams. These findings are a step forward to studying cognition in more complex and naturalistic soundscapes using frequency-tagging.

AbstractAdults with HIV frequently develop a form of mild cognitive impairment known as HIV-associated neurocognitive disorder (HAND), but presumably cognitive decline in older persons with HIV could also be attributable to Alzheimer’s disease (AD). However, distinguishing these two conditions in individual patients is exceedingly difficult, as the distinct neural and neuropsychological features are poorly understood and most studies to date have only investigated HAND or AD spectrum (ADS) disorders in isolation. The current study examined the neural dynamics underlying visuospatial processing using magnetoencephalography (MEG) in 31 biomarker-confirmed patients on the ADS, 26 older participants who met criteria for HAND, and 31 older cognitively normal controls. MEG data were examined in the time–frequency domain, and a data-driven approach was utilized to identify the neural dynamics underlying visuospatial processing. Both clinical groups (ADS/HAND) were significantly less accurate than controls on the task and exhibited stronger prefrontal theta oscillations compared to controls. Regarding disease-specific alterations, those with HAND exhibited stronger alpha oscillations than those on the ADS in frontoparietal and temporal cortices. These results indicate both common and unique neurophysiological alterations among those with ADS disorders and HAND in regions serving visuospatial processing and suggest the underlying neuropathological features are at least partially distinct.
