Hollowed Out
Published in Usva Seregina, Astrid Van den Bossche, Art-Based Research in the Context of a Global Pandemic, 2023
Between the oxymoronic urban quietude and the trouble caused by celluloid doubles, photographs of a city in the grips of a pandemic thereby have the potential to raise the discomfort of the uncanny as they are viewed through the digital realm, the new default home of social and civic ties. Yet the digital itself raises its own kinds of uncanny. The infrastructural uncanny produced by the circulation of fake news, for example, points to our reliance on obscure and ultimately vulnerable publishing ecosystems that are driven by monetary rather than civic concerns (Gray et al., 2020). Likewise, the proliferation of data and its capture through digital platforms smooth over provenance, complexity, nuance, instability, indecision, and indeterminacy. The veneer of digital discourse can equally be a space for exploration if we attune to its haunted qualities: “both science and computational culture are haunted by both the histories and excesses of their own storytelling […] these excesses surface in “queer aggregations” or haunted data to be mined, poached and put to work in newly emergent contexts and settings” (Blackman 2019, xiii).
Staying with the trouble

The configuration of matter is always contextual. It takes place in localized and temporarily bound circumstances. The fact that matter is dynamic and indeterminate at the core does not, per se, make the scientific enterprise impossible. But it does lead to certain recognitions. First, scientific endeavors “work” (that is, they produce knowledge that can be reproduced scientifically) because in their “active intervention” they create an instance of “stabilization” in the ongoing dynamism that is matter. Scientific interventions – or “enactments” – do not alter the inherent indeterminacy and dynamism that is matter, but they do have important consequences. Specifically, they mark matter, leaving traces on it that both enable the reproducibility of scientific inquiries, and shape the future of matter by influencing the configurations that matter-as-indeterminacy can take subsequently.
Convolutional Neural Network for Classification of Skin Cancer Images

Traditional approaches usually use image processing techniques and conventional learning models to classify skin lesion images. For example, Murugan et al. [8] utilized the support vector machine (SVM) as a classifier to determine skin lesion images as benign or melanoma. With different experiments, the experiments show that SVM produced better classification results compared to several other methods. Farooq et al. [9] segmented cancerous areas in the skin lesions by combining active contours and watershed techniques. Later, SVM was used to classify the cancer moles. Finally, an additional classification artificial neural network is used to fine-tune the SVM results and check the indeterminate cases produced from SVM's output. However, these traditional methods highly depend on preprocessing and post-processing steps of images and the hand-crafted features of skin lesion images. These methods are difficult to achieve satisfactory results due to the high variability of size, shape, and texture between healthy skin and damaged skin.
The Needs to Focus on Process and Precise Language in Ethical Determination of cDCD
Published in The American Journal of Bioethics, 2023
Ahmed N. Khan, Robert Klitzman
In the process of dying, a person may exist in, or pass through, a “borderline state in between being determinately alive and determinately dead” (Chiong 2005). Before advances in critical care medicine, this progression might have been unnoticeable and immaterial, but this is not the case with cDCD-NRP. As Chiong writes, one approach to indeterminacy is to “sharpen an originally indeterminate distinction by introducing an artificially defined cutoff” that agrees “with the original distinction in the determinate cases.” In other words, as Bernat describes, “a reasoned judgment must be made about the moment of death that is conceptually coherent, physiologically plausible, and socially acceptable” (Bernat 2013). A parallel example of an artificially defined cutoff in our current society is eighteen as the age of adulthood. Although there is likely no real difference between ages a few months on either side of this cutoff, eighteen serves certain very real legal and societal needs.
Patients’ Experiences of Participation in High-Security, Forensic Psychiatric Care

It appears to be difficult for the person being cared for in a high-security, forensic psychiatric environment to consider participation to be a meaningful concept. In a hospital environment characterised by indeterminate treatment timeframes and where someone else has the power to make decisions, passivity, powerlessness, and uncertainty become apparent. These feelings can be counteracted and relieved by carers or situations where participation is created. The carers’ attitude that creates participation fosters key relationships and counteracts non-participation, thus also promoting participation. Trust and understanding exist in key relationships, which in one sense compensate and go beyond restrictions and incarceration where the relationship itself creates an experienced participation.
Endoscopic ultrasound with combined fine needle aspiration plus biopsy improves diagnostic yield in solid pancreatic masses

The definition of diagnostic yield we used was the percentage of lesions sampled for which a definitive tissue diagnosis was obtained. This is similar to the definition of diagnostic yield used in previous studies [20]. However, a definitive diagnosis may sometimes be unable to discern due to ambiguity of words such as ‘atypical’, ‘indeterminate’, ‘insufficient’, ‘indeterminate’ in pathology reports that make it difficult to discern what is a diagnostic yield or non-diagnostic yield. In our study, ‘non-diagnostic’, ‘indeterminate’, ‘insufficient’, or ‘intermediate’ samples were considered non-diagnostic as they did not infer definitive yields. Other studies have used the term diagnostic yield more variably. Some prospective studies such as Young Bang et al. described the diagnostic yield as ‘diagnostic sufficiency’ or the proportion of patients in whom an on-site diagnosis was established with 3 [8] or 4 [21] passes. Tian et al. [17] seemed to use diagnostic yield and accuracy interchangeably. We used a similar definition of diagnostic accuracy (sum of true positives and true negatives divided by the total number of samples) as Lee et al. [19] and other studies.
