‘Methods for assessing and removing non-specific photoimmunotherapy damage in patient-derived tumor cell culture models’
“Tumor-targeted, activatable photoimmunotherapy (taPIT) has been shown to selectively destroy tumor in a metastatic mouse model. However, the photoimmunoconjugate (PIC) used for taPIT includes a small fraction of non-covalently associated (free) benzoporphyrin derivative (BPD), which leads to non-specific killing in vitro. Here, we report a new treatment protocol for patient-derived primary tumor cell cultures ultrasensitive to BPD photodynamic therapy (BPD-PDT). … The modifications in the protocol suggested here improve in vitro taPIT experiments that lack in vivo mechanisms of free BPD clearance (i.e., lymph and blood flow).”Find the paper and full list of authors at Photochemistry and Photobiology.

Wegst presents primer on ‘Freeze casting’
“When solutions and slurries are directionally solidified, complex dynamics of solvent crystal growth and solvent templating determine the final hierarchical architecture of the freeze-cast material. With continuous X-ray tomoscopy, it is now possible to study in situ intricate and otherwise elusive ice crystal growth and solvent-templating phenomena. … The freeze casting process is attractive because the features of the final hierarchical material architecture … can be custom designed for a given application … [and] can be tailored for applications in, for example, biomedicine, environmental engineering, catalysis, power conversion, and energy generation and storage.Find the paper and full list of authors…

‘Experimentally Probing the Effect of Confinement Geometry on Lipid Diffusion’
“The lateral mobility of molecules within the cell membrane is ultimately governed by the local environment of the membrane. … Here, we prepare model lipid systems on substrates patterned with confined domains of varying geometries constructed with different materials to explore the influences of physical boundary conditions and specific molecular interactions on diffusion. We demonstrate a platform that is capable of significantly altering and steering the long-range diffusion of lipids by using simple oxide deposition approaches, enabling us to systematically explore how confinement size and shape impact diffusion.”Find the paper and authors list in the Journal of Physical Chemistry B.

‘Rapidly Changing Range Limits in a Warming World: Critical Data Limitations and Knowledge Gaps for Advancing Understanding of Mangrove Range Dynamics’
“Climate change is altering species’ range limits and transforming ecosystems. For example, warming temperatures are leading to the range expansion of tropical, cold-sensitive species at the expense of their cold-tolerant counterparts. In some temperate and subtropical coastal wetlands, warming winters are enabling mangrove forest encroachment into salt marsh, which is a major regime shift that has significant ecological and societal ramifications. Here, we synthesized existing data and expert knowledge to assess the distribution of mangroves near rapidly changing range limits in the southeastern USA.”Find the paper and full list of authors in Estuaries and Coasts.

‘Revisiting the Roles of Catalytic Residues in Human Ornithine Transcarbamylase’
“Human ornithine transcarbamylase (hOTC) is a mitochondrial transferase protein involved in the urea cycle and is crucial for the conversion of toxic ammonia to urea. Structural analysis coupled with kinetic studies of Escherichia coli, rat, bovine, and other transferase proteins has identified residues that play key roles in substrate recognition and conformational changes but has not provided direct evidence for all of the active residues involved. … Here, computational methods were used to predict the likely active residues of hOTC; the function of these residues was then probed with site-directed mutagenesis and biochemical characterization.”Find the paper and authors list in Biochemistry.

‘Synthesizing Tight Privacy and Accuracy Bounds via Weighted Model Counting’
“Programmatically generating tight differential privacy (DP) bounds is a hard problem. Two core challenges are (1) finding expressive, compact and efficient encodings of the distributions of DP algorithms and (2) state space explosion stemming from the multiple quantifiers and relational properties of the DP definition. We address the first challenge by developing a method for tight privacy and accuracy bound synthesis using weighted model counting on binary decision diagrams. … We address the second challenge by developing a framework for leveraging inherent symmetries in DP algorithms.” Find the paper and full list of authors at ArXiv.

‘The Joint Effect of Task Similarity and Overparameterization on Catastrophic Forgetting — An Analytical Model’
“In continual learning, catastrophic forgetting is affected by multiple aspects of the tasks. Previous works have analyzed separately how forgetting is affected by either task similarity or overparameterization. In contrast, our paper examines how task similarity and overparameterization jointly affect forgetting in an analyzable model. Specifically, we focus on two-task continual linear regression, where the second task is a random orthogonal transformation of an arbitrary first task (an abstraction of random permutation tasks). We derive an exact analytical expression for the expected forgetting — and uncover a nuanced pattern.” Find the paper and full list of authors at ArXiv.

‘Stability of P2P Networks Under Greedy Peering (Full Version)’
“Major cryptocurrency networks have relied on random peering choice rules for making connections in their peer-to-peer networks. Generally, these choices have good properties, particularly for open, permissionless networks. Random peering choices however do not take into account that some actors may choose to optimize who they connect to such that they are quicker to hear about information being propagated in the network. In this paper, we explore the dynamics of such greedy strategies.” Find the paper and full list of authors at ArXiv.
