Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Bearing Black [PDF]

open access: yesJournal for Social Action in Counseling & Psychology, 2013
In this essay I critically examine the idea of race in light of the killing of Trayvon Martin, an African-American unarmed teenager, in Florida in February 2012. I utilize ideas from liberation psychology, including psychic colonization, and depth psychology, including cultural complex, to explore the racialized black as a colonized, traumatized other.

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Bearing-Based Formation Maneuvering

open access: yes, 2015
This paper studies the problem of multi-agent formation maneuver control where both of the centroid and scale of a formation are required to track given velocity references while maintaining the formation shape.

PASSIVE TORQUE SIMULATION OF SMALL ANGULAR CONTACT BEARING AT HIGH SPEED [PDF]

open access: yes, 2017
Description of common ball bearing torque models was presented and adopted to the complex thermo-mechanical model of the high speed spindle. Ball bearing passive torque was measured on the own high-speed spindle design.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Acoustic positioning and tracking in Portsmouth Harbour, New Hampshire [PDF]

open access: yes, 2007
Portsmouth Harbor, New Hampshire, is frequently used as a testing area for multibeam and sidescan sonars, and is the location of numerous ground-truthing studies. Having the ability to accurately position underwater sensors is an important aspect of this
