Robust Visual Tracking Via Online Low-rank Sparse Representation

工程科学与技术, 2017
:The gray value features of images were used to describe targets in robust visual tracking via L1 minimization (L1 tracking algorithm).However,the ignorance of structural information between the templates and inaccurate modeling of target appearance ...

Single‐cell atlas of neuroglial dynamics in SNCA‐A53T Parkinson's disease mouse model

Animal Models and Experimental Medicine, EarlyView.
We performed single‐cell RNA sequencing of midbrain and striatal tissues from SNCA‐A53T Parkinson's disease (PD) mice, revealing glia‐enriched PD‐risk gene signatures and disease‐specific subpopulations. Transcriptional dysregulation of key TFs (e.g., Rorb, Foxc1) and enhanced neuroinflammatory signaling (SEMA, CCL, MIF) were identified.

Spectroscopic and In Silico Determination of the Structural and Antioxidant Properties of Essential Oils From Lavandula Species Cultivated in the Silivri Region of Istanbul

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plants are important sources of bioactive compounds that contribute to nutrition, health maintenance, and disease prevention. In this study, the chemical composition and antioxidant potential of essential oils obtained from Lavandula angustifolia “Sevtopolis” and Lavandula × intermedia cultivated in the Silivri region of Istanbul were ...

PbAT: A user‐friendly R/Shiny platform for data‐driven decision support in crop improvement

Applications in Plant Sciences, EarlyView.
Abstract Premise Modern plant breeding requires robust analysis of complex, multi‐environment datasets to identify superior genotypes. Although R offers powerful statistical packages, their use often requires programming expertise. Existing graphical user interface (GUI)‐based tools are either limited in scope or not openly accessible, leaving breeders

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Coherence‐Gated Wrapped‐Phase InSAR With Matrix‐Based Uncertainty Diagnostics for Burial‐Mound Hotspot Ranking (Sicily, Italy)

Archaeological Prospection, EarlyView.
ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.
