Authors: Mamoor Shahan
Published: June 2023

Skin cancer is diagnosed in nearly 1.5 million patients each year (1). While patients with basal and squamous cell carcinomas are provided with 5-year survival rates at nearly 100% and 90%, respectively, patients diagnosed with cutaneous melanoma (metastatic melanoma) are provided 5-year survival rates at 91.4% at stage I and 24.6% at stage IV (2-5). We mined public and published microarray datasets (6, 7) to determine in an unbiased fashion and at the level of the transcriptome genes most differentially expressed in the primary tumors of patients with the deadliest type of skin cancer, malignant melanoma. We found significant differential expression of the gene encoding tenascin C, TNC, when comparing melanoma cell line gene expression to normal human melanocytes. TNC mRNA was present at significantly higher quantities in melanoma cell cultures as compared to normal melanocytes. Analysis of human survival data revealed that expression of TNC in melanoma tissues was correlated with overall survival in patients with malignant melanoma. TNC expression changes may be important for the initiation or progression of malignant melanoma in humans.

Musik adalah salah satu hal penting dalam gereja karena musik adalah unsur yang tidak terpisahkan dari liturgi atau tata ibadah gerejawi. Penggunaan alat musik dan lagu-lagu dalam ibadah sering menjadi pertentangan sehingga musik harus dikelola dengan baik. Ada tiga hal yang perlu diperhatikan dalam pengelolaan musik dalam gereja yaitu: fungsi musik gerejawi; unsur-unsur musik gerejawi yaitu: tempo, irama, suara, intro, interludium, postludium; dan pemilihan lagu yang tepat dalam penyembahan.Musik gereja menjadi benar apabila di pahami berdasarkan prinsip-prinsip yang terkandung dalam firman Allah. dengan memiliki pemahan yang benar akan makna, tujuan,siapa dan bagaimana serta kapan musik gerejawi itu di lakakukan,maka penyembahan kita kepada Allah melalui musik dan nyanyian akan membangun iman dan memuliakan Allah.Musik dan nyanyian gerejawi sangat mutlak di dasari oleh kehendak Allah. Musik gerejawi bukan merupakan pilihan,melainkan kewajiban bagi setiap gereja sebagai respon atas karya penebus Allah dalam hidupnya. Musik dan nyanyian gerejawi bukan dalam rangka sebagai pengantar antara unsur yang satu dengan unsur yang lain dalam sebuah susunan acara liturgi,dan bukan pula dalam rangka suatu aktifitas kegiatan bersama yang menyenangkan untuk menyanyikan lagu-lagu kesanyangan.perjumpaan dengan Allah melalui karya pemeliharaanya pada setiap waktu, itulah yang menjadi sebuah pengerak untuk mengerakan musik dan nyanyian pujian kepada Allah.

As it was comprehensively examined in my AVİM report of last year titled “The Pontus Narrative and Hate Speech,” Pontus Greek narratives in relation to the developments during First World War and assertions of a ‘Pontus Genocide’ was invented and propagated in Greece and among the Greek diaspora during the late 1980s. After the pressures from Pontian lobbies, the Greek government passed “a motion on 24 February 1994 that May 19 be day of commemoration for the Pontian Genocide” and the Greek parliament adopted a law declaring May 19 as a day of remembrance of the “Genocide of the Pontian Greeks.

Research involving digital games and language learning is rapidly growing. One advantage of using digital games to support language learning is the ability to collect data on students learning in real time. In this study, we use educational data mining methods to explore the relationship between in-game data and elementary students’ Chinese language learning. Thirty-six students in the sixth grade played a digital game for eight 25-minute sessions as part of their Chinese Dual Language Immersion classroom instruction. We used classification and regression tree analyses and cluster analyses to explore how in-game indicators, such as battles, time spent reading a text, and the use of an in-game glossing tool are associated with language learning and change in affect. The results indicate that time on task and use of the glossing tool were the most important variables in determining language learning gains. We also identified four subgroups of gameplay styles. While there were no significant differences in learning or affective factors, based on the subgroups, these gameplay styles allow for a more individualized approach to analyzing learning within digital environments.
Learning health systems: pathways to progress
Authors: Sheikh Kabir
Published: June 2023

Learning – at individual, team, organization and crossorganization levels – is fundamental to health systems strengthening and the achievement of health goals. Yet, many health systems, especially in low-and middle-income countries (LMICs), still do not have adequate capacity to generate and use the knowledge that they need to be effective. Investments in learning activities tend to be a remarkably small proportion of overall investments in health programmes and systems, and learning-focused activities have historically not found place or favour in budgets when compared with other health system priorities. Why is learning so neglected? One explanation is that the many pressures on health systems crowd out the “softer” work of learning, which is perceived as having less immediate or predictable benefits. Another is that the conceptualization of a learning health system, its benefits and how it can be built have not been well articulated. This report, therefore, makes the case for such systems.
Universal techniques for mineral identification in thin-section
Authors: Walton Craig
Published: June 2023

Mineral identification using an optical microscope forms a key part of every introductory course in Earth Sciences. The presence or absence of particular minerals and their textural relationships to one another - that is, the visual impression of the size, shape, and arrangement of grains/crystals/particles in a rock - act as keys to the origin and evolution of the Earth system. Indeed, many would claim that the best geologists have simply seen the most rocks (/minerals). Whilst this is no longer strictly true in an age of increasingly abstracted geochemical and statistical approaches, optical microscope studies will (or at least should) remain at the heart of geology for the foreseeable future.So we come to colour-blindness and visual impairment in optical microscopy. A reasonable percentage of the population are colour-blind or visually impaired. Nowadays, plenty of tools exist to level the playing field and help both tutors and students to see eye-to-eye. This document attempts to make systematic use of those tools.In Chapter 1, I briefly review some essential points to bear in mind when approaching rock forming mineral classification, which together help to shrink a complicated problem (whether colour blind or not) down to something more tractable. In Chapter 2, I lay out several systematic approaches for mineral and rock classification. In Chapter 3, I present collected optical microscope images of common rock-forming minerals in plane polarised light (PPL) and cross polarised light (XPL). Using the Color Oracle software, I try to capture how the same images would appear to individuals with differing types of colour blindness. Throughout, the goal is to develop a framework of 'universal' diagnostic mineral features in thin section, i.e., features that should be both possible to identify for a broad range of individuals, and possible to describe using language that translates directly from one person to another.
Getting LOST: A conceptual framework for supporting and enhancing spatial navigation in aging
Authors: Weisberg Steven Marc , Ebner Natalie C. , Seidler Rachael
Published: June 2023

Spatial navigation is more difficult and effortful for older than younger individuals, a shift which occurs for a variety of neurological, physical, and cognitive reasons associated with aging. Despite a large body of evidence documenting age-related deficits in spatial navigation, comparatively less research addresses how to facilitate more effective navigation behavior for older adults. Since navigation challenges arise for a variety of reasons in old age, a one-size-fits-all solution is unlikely to work. Here, we introduce a framework for the variety of spatial navigation challenges faced in aging, which we call LOST – Location, Orientation, Spatial mapping, and Transit. The LOST framework builds on evidence from the cognitive neuroscience of spatial navigation, which reveals distinct components underpinning human wayfinding. We evaluate research on navigational aids – devices and depictions – which help people find their way around; and we reflect on how navigation aids solve (or fail to solve) specific wayfinding difficulties faced by older adults. In summary, we emphasize a bespoke approach to improving spatial navigation in aging, which focuses on tailoring navigation solutions to specific navigation challenges. Our hope is that by providing precise support to older navigators, navigation opportunities can facilitate independence and exploration, while minimizing the danger of becoming lost. We conclude by delineating critical knowledge gaps in how to improve older adults’ spatial navigation capacities that the novel LOST framework could guide to address.
Iron content affects age group differences in associative learning-related fMRI activity
Authors: Petok Jessica R. , Merenstein Jenna Louise , Bennett Ilana J.
Published: June 2023

Brain regions accumulate different amounts of iron with age, with older adults having higher iron in basal ganglia nuclei (globus pallidus, putamen, caudate) relative to the hippocampus and cortex. This has important implications for functional magnetic resonance imaging (fMRI) studies in aging as the presence of iron may influence both neuronal functioning as well as the measured fMRI (BOLD) signal, and these effects will vary across age groups and brain regions. To test this hypothesis, the current study examined the effect of iron on age group differences in task-related activity within each basal ganglia nuclei and the hippocampus. Twenty-eight younger and 22 older adults completed an associative learning task during fMRI acquisition. Iron content was measured from a multi-echo gradient echo sequence. As previously reported, older adults learned significantly less than younger adults and had significantly higher iron content (QSM, R2*) in all basal ganglia nuclei, but not the hippocampus. In the hippocampus (early task stage) and globus pallidus (late task stage), older adults had significantly higher learning-related activity than younger adults both before and after controlling for iron. In the putamen (late task stage), however, younger adults had significantly higher learning-related activity than older adults that was only seen after controlling for iron. These findings support the notion that age-related increases in iron influence both neuronal functioning and the measured fMRI signal in select basal ganglia nuclei. Moreover, previous fMRI studies in aging populations may have under-reported age group differences in task-related activity by not accounting for iron within these regions.

This work contributes an event-driven visual-tactileperception system, comprising a novel biologically-inspired tactilesensor and multi-modal spike-based learning. Our neuromorphicfingertip tactile sensor, NeuTouch, scales well with the number oftaxels thanks to its event-based nature. Likewise, our VisualTactile Spiking Neural Network (VT-SNN) enables fast perceptionwhen coupled with event sensors. We evaluate our visual-tactilesystem (using the NeuTouch and Prophesee event camera) on tworobot tasks: container classification and rotational slip detection.On both tasks, we observe good accuracies relative to standarddeep learning methods. We have made our visual-tactile datasetsfreely-available to encourage research on multi-modal eventdriven robot perception, which we believe is a promising approachtowards intelligent power-efficient robot systems.
