Automated MRI Segmentation of Brainstem Nuclei Critical to Consciousness
Human Brain Mapping, Volume 46, Issue 14, 01 October 2025.To advance coma and consciousness research, we developed a method for segmenting brainstem ascending arousal network nuclei from MRI scans. We validated automated segmentations of these nuclei in normative brain scans from multiple MRI modalities, as well as in patients with Alzheimer's disease and traumatic brain injury.

Head &Neck, Volume 47, Issue 10, Page 2835-2844, October 2025.ABSTRACT Background Evaluating the minimum distance (dTICA) between the internal carotid artery (ICA) and tonsillar tumors (TT) on imaging is essential for preoperative planning; we propose a tool to automatically extract dTICA. Methods CT scans of 96 patients with TT were selected from the cancer imaging archive.

Complex continued fractions with restricted entries
Electronic Journal of Differential Equations, 1998 We study special infinite iterated function systems derived from complex continued fraction expansions with restricted entries. We focus our attention on the corresponding limit set whose Hausdorff dimension will be denoted by $h$. Our primary goal is to

Journal of Biophotonics, Volume 18, Issue 10, October 2025.Bright‐field images of unstained smears. (1) Sparse erythrocytes allow straightforward intensity‐ or phase‐based segmentation. (2) Overlapping cells blur boundaries, causing over‐ or under‐segmentation and lowering rule‐based accuracy, thus motivating overlap‐aware algorithms for reliable downstream feature extraction and classification.

On the Hausdorff dimension of radial slices
Annales Fennici MathematiciLet \(t \in (1,2)\), and let \(B \subset \mathbb{R}^{2}\) be a Borel set with \(\dim_{\mathrm{H}} B > t\). I show that \(\mathcal{H}^{1}(\{e \in S^{1} \colon \dim_{\mathrm{H}} (B \cap \ell_{x,e}) \geq t - 1\}) > 0\) for all \(x \in \mathbb{R}^{2} \setminus E\), where \(\dim_{\mathrm{H}} E \leq 2 - t\).

Arbitrary‐Scale Point Cloud Upsampling via Enhanced Geometric Spatial Consistency
CAAI Transactions on Intelligence Technology, Volume 10, Issue 5, Page 1291-1305, October 2025.ABSTRACT Point cloud upsampling is an essential yet challenging task in various 3D computer vision and graphics applications. Existing methods often struggle with limitations such as the generation of outliers or shrinkage artifacts. Additionally, these methods usually ignore the overall spatial structure of point clouds, leading to suboptimal results.

Market Allocations Under Conflation of Goods
International Economic Review, Volume 66, Issue 4, Page 1681-1691, October 2025.ABSTRACT We study competitive equilibria in exchange economies when a continuum of goods is conflated into a finite set of commodities. The design of conflation choices affects the allocation of scarce resources among agents, by constraining trading opportunities and shifting competitive pressures.
