Coupling between corotation and Lindblad resonances in the elliptic planar three-body problem

open access: yes, 2013
We investigate the dynamics of two satellites with masses $\mu_s$ and $\mu'_s$ orbiting a massive central planet in a common plane, near a first order mean motion resonance $m$+1:$m$ ($m$ integer).

Thermometric Based‐Microswimmers with Chemical and Optical Engines

open access: yesAdvanced Intelligent Systems, EarlyView.
Temperature sensing at small scales is typically performed using passive luminescent particles. Here, an alternative approach is demonstrated by integrating upconversion thermometry into self‐propelled microswimmers powered by chemical fuels or light. This strategy offers a step toward dynamic thermal sensing at the microscale, relevant to both lab‐on ...

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

MDSGene Systematic Review of Common Forms of Dominant Hereditary Spastic Paraplegia: Novel Insights

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Hereditary spastic paraplegia (HSP) is a neurodegenerative disorder characterized by progressive spasticity and lower limb weakness. The most common forms of autosomal dominant HSP are caused by pathogenic variants in SPAST (SPG4 or HSP‐SPAST), ATL1 (SPG3A or HSP‐ATL1), and REEP1 (SPG31 or HSP‐REEP1).

Seasonal and Regional Variability of Long-Wave Effective Radiation in China and Associated Modulating Factors

open access: yesAdvances in Meteorology, 2020
Variations in all-sky and clear-sky long-wave effective radiation (LER) in China during the period 2001–2016 were determined using monthly radiative datasets from the Clouds and the Earth’s Radiant Energy System (CERES).

Ler Aristófanes?

open access: yesRevista do Museu de Arqueologia e Etnologia, 2004
O objetivo deste estudo é discutir, à luz da Poética de Aristóteles e de estudos de semiologia teatral, a possibilidade de leitura da comédia antiga do mesmo modo como se lê a tragédia. A questão colocada é: será que a comédia de Aristófanes pode, como a tragédia, atingir seu fim apenas com a leitura?

Rethinking Public Administration Reform: Institutional Layering of Bureaucratic, Managerial and Community Logics Over Time in Nigeria's Tax Administration

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT The reform of public institutions has attracted sustained attention in both scholarship and policymaking. Increasingly, however, there is growing recognition that reforms are rarely implemented in an institutional vacuum. Instead, new reforms are layered onto existing arrangements, producing hybrid institutional landscapes shaped by prior ...
