‘A Study of Multi-Factor and Risk-Based Authentication Availability’
“Password-based authentication (PBA) remains the most popular form of user authentication on the web despite its long-understood insecurity. Given the deficiencies of PBA, many online services support multi-factor authentication (MFA) and/or risk-based authentication (RBA) to better secure user accounts. … In this paper, we present a study of 208 popular sites in the Tranco top 5K that support account creation to understand the availability of MFA and RBA on the web … and how logging into sites through more secure SSO providers changes the landscape of user authentication security.” Find the paper and full list of authors at USENIX Security…

‘Wrapped in Story: The Affordances of Narrative for Citizen Science Games’
“Citizen science games enable public participation in scientific research, yet these games often struggle to engage wide audiences. As a potential solution, some game developers look to narrative as an experience-enhancing feature. … We investigated the effects of wrapping a story around the tutorial puzzles of the citizen science game Foldit. We found that the narrative increased the time players spent engaging with the game’s tutorial and its scientific puzzles but did not substantially affect their progress through the tutorial.” Find the paper and full list of authors in the 18th International Conference on the Foundations of Digital Games proceedings.

‘Iterative Soft Shrinkage Learning for Efficient Image Super-Resolution’
“Image super-resolution (SR) has witnessed extensive neural network designs from CNN to transformer architectures. However, prevailing SR models suffer from prohibitive memory footprint and intensive computations, which limits further deployment on edge devices. This work investigates the potential of network pruning for super-resolution to take advantage of off-the-shelf network designs and reduce the underlying computational overhead. … We adopt unstructured pruning with sparse models directly trained from scratch.” Find the paper and full list of authors at ArXiv.

‘UniControl: A Unified Diffusion Model for Controllable Visual Generation in the Wild’
“Achieving machine autonomy and human control often represent divergent objectives in the design of interactive AI systems. Visual generative foundation models such as Stable Diffusion show promise in navigating these goals, especially when prompted with arbitrary languages. However, they often fall short in generating images with spatial, structural or geometric controls. … In response, we introduce UniControl, a new generative foundation model that consolidates a wide array of controllable condition-to-image (C2I) tasks within a singular framework, while still allowing for arbitrary language prompts.” Find the paper and full list of authors at ArXiv.

‘Linearity of Relation Decoding in Transformer Language Models’
“Much of the knowledge encoded in transformer language models (LMs) may be expressed in terms of relations: relations between words and their synonyms, entities and their attributes, etc. We show that, for a subset of relations, this computation is well-approximated by a single linear transformation on the subject representation. Linear relation representations may be obtained by constructing a first-order approximation to the LM from a single prompt, and they exist for a variety of factual, commonsense, and linguistic relations.” Find the paper and full list of authors at ArXiv.

‘TikTok as Algorithmically Mediated Biographical Illumination: Autism, Self-Discovery and Platformed Diagnosis on #Autisktok’
“Scholarship in the sociology of medicine has tended to characterize diagnosis as disruptive to one’s self-concept. This categorization, though, requires reconsideration in light of public conversations about mental health and community building around neurocognitive conditions, particularly among youth online. … We explored the shifting nature of [‘biographical illumination’] through the case of TikTok. Combining quantitative and qualitative methods, we argue that TikTok serves as a space to discuss diagnosis and refine one’s sense of self as a result of diagnosis.” Find the paper and full list of authors at New Media & Society.

NIH grant to support research of chemotherapy alternative, ‘photomedicine’
“Photomedicine avoids traditional side effects of systemic chemotherapy, yet effective outcomes are dependent on direct irradiation from an external light source that limits the scope and the types of cancers that may be treated. This proposal develops a precision photomedicine platform that exploits natural disease-homing properties of the immune system to mediate bioluminescence-activated phototherapy in combination with established technology to deliver photoactive therapeutic agents selectively to tumor cells. Successful, proof-of-concept studies will establish a new paradigm of systemic, whole-body phototherapy by enabling immune cell-based light delivery to deep and diffuse metastatic disease.”

Whitfield-Gabrieli receives NIH grant to study adolescent depression with ‘real-time fMRI neurofeedback’
“Adolescents experience alarmingly high rates of major depressive disorder (MDD), and these episodes are highly recurrent and increase suicide risk. … Rumination (i.e., repetitive, negative patterns of thinking typically focused on the self) contributes to MDD onset, maintenance, and recurrence as well as predicts treatment non-response and relapse. Mindfulness meditation has been shown to suppress the default mode network (DMN), a set of brain regions that are overactive in depression. … We are launching a large scale, clinical trial to do a mindfulness based real-time fMRI neurofeedback intervention in adolescents with MDD in order to quiet the DMN and mitigate…

Eskew awarded NSF grant to study response time in human vision
“The project will use variations on a classic method called response time (RT) measurement, which has human participants respond as quickly as possible to the presentation of carefully-controlled visual patterns. One goal is to demonstrate that the fastest RTs are triggered by the very early responses in the photoreceptors of the retina of the eye. Two parallel pathways in the visual system called ON and OFF pathways, generate opposite-polarity responses. A second goal is to test the hypothesis that these two pathways can be measured and studied separately using these speeded behavioral responses.”

Champion receives NSF grant to study the interrelation of biology and quantum mechanics
“This work will enhance understanding of how biology integrates quantum behavior into macromolecular function. Proteins and macromolecules have evolved to rely, at least to some degree, on underlying quantum phenomena such as tunneling and spin coherence. The biological outcomes depend on the interplay between the scaffold of the protein (which is often treated classically) and the quantum behavior found within more localized regions of the protein. Investigators within this collaboration will draw upon both experimental and theoretical efforts that focus on hydrogen tunneling and vibrational energy transport in lipoxygenase catalysis as well as on optically excited radical pair formation, spin…

Tilly uses NSF grant to apply ‘mitochondrial lineage tracing’ to the development of in-vivo mammals
“This project combines our technological advancements in mitochondrial analysis and nanosorting with an in-vivo mitochondrial lineage tracing approach, which will enable us able to map the developmental fate of specific mitochondrial subtypes in mammalian eggs through post-fertilization to the point in early embryogenesis when the inner cell mass and trophectoderm are specified at the first cell-fate decision. This project will also explore the novel concept that subtypes of mitochondria, [differing] in their biochemical properties, proteomic landscapes and segregation patterns during asymmetric cell divisions, serve as transcription factor shuttles that then guide stem cell fate decisions and lineage commitment during development.”
