Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

open access: yesAdvanced Science, EarlyView.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

A Machine Learning Scheme for Estimating the Diameter of Reinforcing Bars Using Ground Penetrating Radar

open access: yesIEEE Geoscience and Remote Sensing Letters, 2020
Ground penetrating radar (GPR) is a well-established tool for detecting and locating reinforcing bars (rebars) in concrete structures. However, using GPR to quantify the diameter of rebars is a challenging problem that current processing approaches fail ...

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

open access: yesAdvanced Science, EarlyView.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

Natural stone assessment with ground penetrating radar [PDF]

open access: yesEstonian Journal of Earth Sciences, 2008
The usability of ground penetrating radar in quality assessment of natural stone deposits was tested in porphyritic granite and soapstone. The main interest was to evaluate how the soundness, fracturing, and physical defects can be studied with the ...

Cellular Identity Crisis: RD3 Loss Fuels Plasticity and Immune Silence in Progressive Neuroblastoma

open access: yesAdvanced Science, EarlyView.
Researchers discovered that therapy‐induced loss of RD3 protein in neuroblastoma triggers a dangerous shift: cancer cells become more stem‐like, invasive, and resistant to treatment while evading immune detection. RD3 loss suppresses antigen presentation and boosts immune checkpoints, creating an immune‐silent environment.

Theory of ground-penetrating radars III [PDF]

open access: yesjiip, 1998
Abstract - The governing equations are Maxwell’s. The source of the current is either j = ey δ(z − z 0)δ(x)f(t) or eϕ δ(z − z 0)δ(r − r 0)f(t) (straight wire or loop of current, f(t) is a pulse).
