Subsocial Neotropical Doryphorini (Chrysomelidae, Chrysomelinae): new observations on behavior, host plants and systematics

ZooKeys, 2013
A summary of literature, documented observations and field studies finds evidence that mothers actively defend offspring in at least eight species and three genera of Neotropical Chrysomelinae associated with two host plant families.

Transition from the Seniority to the Anharmonic Vibrator Regime in Nuclei [PDF]

, 1996
A recent analysis of experimental energy systematics suggests that all collective nuclei fall into one of three classes -- seniority, anharmonic vibrational, or rotational -- with sharp phase transitions between them.

A new toothless pterosaur from the Early Cretaceous Jehol Biota with comments on the Chaoyangopteridae

Scientific Reports, 2023
The Chaoyangopteridae is a clade of azhdarchoid pterosaurs that stands out in China, particularly in the Jehol Biota, as a Cretaceous group of medium-sized and high-crested pterosaurs. Herein, we describe a new species, Meilifeilong youhao gen.

Scaling Properties of the Giant Dipole Resonance Width in Hot Rotating nuclei [PDF]

, 1998
We study the systematics of the giant dipole resonance width $\Gamma$ in hot rotating nuclei as a function of temperature $T$, spin $J$ and mass $A$.

Loose Ends for the Exomoon Candidate Host Kepler-1625b [PDF]

, 2020
The claim of an exomoon candidate in the Kepler-1625b system has generated substantial discussion regarding possible alternative explanations for the purported signal. In this work we examine in detail these possibilities.

Caste stone formation in the MgO-H2O-organo system – Effect of citric, malic or acetic acid and MgO reactivity on type and composition of castables

Case Studies in Construction Materials, 2021
Consolidation of MgO castables by organic acids is a common technique for various applications, but the distinct hardening mechanisms of caste stone formation are still poorly constrained.

First observation on courtship behavior of short-tailed viper snake, Gloydius saxatilis (Squamata: Viperidae) in Korea

Journal of Asia-Pacific Biodiversity, 2017
Most reptile species have their own mating patterns. Therefore, courtship behaviors are important factors in understanding taxonomic features and species-specific breeding habits in the genus.

Probing the cosmic acceleration from combinations of different data sets

, 2010
We examine in some detail the influence of the systematics in different data sets including type Ia supernova sample, baryon acoustic oscillation data and the cosmic microwave background information on the fitting results of the Chevallier-Polarski ...

The secretarybird dilemma: identifying a bird species from the Temple of Hatshepsut at Deir el-Bahari [PDF]

Polish Archaeology in the Mediterranean, 2018
Known from a few representations in Predynastic Egyptian art, the secretarybird has otherwise been elusive, in the art of Pharaonic Egypt as well as the scientific discourse on iconographic imagery of birds in ancient Egypt.
