- Abstract:
- In four dimensions, two metrics that are conformally related define the same Hodge dual operator on the space of two‐forms. The converse, namely, that two metrics that have the same Hodge dual are conformally related, is established. This is true for metrics of arbitrary (nondegenerate) signature. For Euclidean signature a...

- Abstract:
- A radio frequency-free electromagnetostatic (EMS) cell devised for electron-capture dissociation (ECD) of ions has been retrofitted into the collision-induced dissociation (CID) section of a triple quadrupole mass spectrometer to enable recording of ECD product-ion mass spectra and simultaneous recording of ECD-CID product-ion mass spectra. This modified instrument can be used...

- Abstract:
- Age is a recognized risk factor for amyotrophic lateral sclerosis (ALS), a paralytic disease characterized by progressive loss of motor neurons and neuroinflammation. A hallmark of aging is the accumulation of senescent cells. Yet, the pathogenic role of cellular senescence in ALS remains poorly understood. In rats bearing the ALS-linked...

- Abstract:
- This study evaluated effects of Positive Action, a school-based social-emotional and character development (SECD) intervention, on indicators of positive youth development (PYD) among a sample of low-income, ethnic minority youth attending 14 urban schools. The study used a matched-pair, cluster-randomized controlled design at the school level. A multiple-measure self-report protocol...

- Abstract:
- Microglia and reactive astrocytes accumulate in the spinal cord of rats expressing the Amyotrophic lateral sclerosis (ALS)-linked SOD1ᴳ⁹³ᴬ mutation. We previously reported that the rapid progression of paralysis in ALS rats is associated with the appearance of prolifer- ative astrocyte-like cells that surround motor neurons. These cells, designated as Aberrant...

- Abstract:
- PURPOSE—We examined the effects of Positive Action (PA), a school-based social-emotional learning and health promotion program, on the emotional health of predominately low-income and ethnic minority urban youth. METHODS—The study was a matched-pair, cluster-randomized controlled trial involving 14 Chicago public schools. Outcomes were assessed over a 6-year period of program...

- Abstract:
- BACKGROUND: School-based social-emotional and character development (SECD) programs can influence not only SECD, but also academic-related outcomes. The purpose of this study was to evaluate the impact of one SECD program, Positive Action (PA), on educational outcomes among low-income, urban youth. METHODS: The longitudinal study used a matched-pair, cluster-randomized controlled...

- Abstract:
- The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon¹⁻³. With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental...
