Occurrence of immature forms of culicids (Insecta: Diptera) in the northeastern region of Brazil
Revista Brasileira de Parasitologia VeterináriaThe Culicidae family is represented by approximately 3,610 species, among which many are involved in transmission of pathogens and parasites, thus presenting great medical-veterinary importance. In Brazil, the state of Pernambuco is considered an endemic

The Madden-Julian Oscillation: A Tool for Regional Seasonal Precipitation Outlooks?
Atmosphere, 2017 The Madden-Julian Oscillation (MJO) is an important intraseasonal climate signal which circles the global tropics, but also impacts extratropical weather regimes.

Spring Changeover of the Middle Atmosphere Circulation Compared with Rocket Wind Data up to 80 Km [PDF]
, 1984 The middle atmosphere circulation is governed by two seasonal basic states in winter and summer, twice a year separated by relatively shortlived reversal periods.

Advanced Science, EarlyView.Seasonal cold adaptation is vital for insect survival, yet the molecular mechanisms linking diapause to mitochondrial resilience remain largely unresolved. We identify ascaroside C9 (asc‐C9) as a key endocrine signal that enhances diapause survival during cold stress by activating the AKHR–PGC1α–UCP4 axis, thereby driving cold‐induced lipolysis and ...

Descriptive Seasonal Adjustment by Minimizing Perturbations [PDF]
, 1982 The seasonal adjustment method proposed by Schlicht (1981) can be viewed as a method that minimizes non-stochastic deviations (perturbations). This interpretation gives rise to a critique of the seasonality criterion used there.

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques
Advanced Science, EarlyView.Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.

DNA Nanostructure‐Templated Multivalency Enables Broad‐Spectrum Virus Inhibition
Advanced Science, EarlyView.A honeycomb‐shaped DNA nanostructure is introduced that organizes nanobodies or aptamers into trimeric clusters mirroring the native hemagglutinin arrangement on influenza viruses. This geometry‐matched multivalency enhances binding avidity by up to 1000‐fold, resulting in robust, broad‐spectrum viral neutralization and a 30–55% improvement in host ...

Finance and Economics Discussion Series, 2006 Seasonal adjustment usually relies on statistical models of seasonality that treat seasonal fluctuations as noise corrupting the `true' data. But seasonality in economic series often stems from economic behavior such as Christmas-time spending.
