ABSTRACT Land degradation poses significant challenges to maintaining food–water–energy (FWE) security, particularly in rapidly urbanizing regions. The ecosystem services (ES) related to FWE are critical for sustainable regional development. Yet, rapid urbanization in the Beijing–Tianjin–Hebei region has altered land use and ecological patterns ...

North-south asymmetry in activity on the Sun and cosmic ray density gradients [PDF]
The marked N-S asymmetry in solar activity (with predominant activity in the Sun's Northern Hemisphere) during the 1960's could certainly account for a S-pointing cosmic ray gradient.

ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Why do planetary wave number one and the ozone transport vary annually in the Northern Hemisphere and semiannually in the Southern Hemisphere [PDF]
Evidence is cited from these studies and those of others showing the different nature of the yearly variations of the middle atmospheres of the Northern and Southern Hemispheres.

Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Implications of Viking color data for evolution of the Amenthes Region, Mars [PDF]
In the Eastern Hemisphere of Mars, where the hemispheric dichotomy is not overlain by relatively recent flows from the Tharsis volcanoes, the Mars cratered terrain boundary (CTB) now exists as highly fractured terrain juxtaposed with the smooth plains of

Voice and Speech in Atypical Parkinsonian Disorders
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

Multimodal Imaging Investigation of the Dentato‐Thalamo‐Cortical Pathway in Friedreich's Ataxia
Abstract Background Friedreich's ataxia (FRDA) is a spinocerebellar neurodegenerative disorder. The dentato‐thalamo‐cortical (DTC) pathway, an important cerebellar output involved in motor control, plays a crucial role in the neural mechanisms underlying ataxia symptoms in FRDA.
