New data about hoverflies diversity (Insecta: Diptera: Syrphidae) on the Fruška Gora mountain, Serbia [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2002
The hoverflies fauna of the Fruška Gora Mountain is well known on account of long-term investigations conducted on the location (1956-2002). Previously, the list of hoverflies had included 203 species (Vujić and Glumac, 1994). Based on new investigations,

Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

open access: yesSmall, EarlyView.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Linguistic Evidence Suggests that Xiōng‐nú and Huns Spoke the Same Paleo‐Siberian Language

open access: yesTransactions of the Philological Society, EarlyView.
Abstract The Xiōng‐nú were a tribal confederation who dominated Inner Asia from the third century BC to the second century AD. Xiōng‐nú descendants later constituted the ethnic core of the European Huns. It has been argued that the Xiōng‐nú spoke an Iranian, Turkic, Mongolic or Yeniseian language, but the linguistic affiliation of the Xiōng‐nú and the ...

Association of adipose tissue inflammation and physical fitness in older adults

open access: yesImmunity & Ageing
An active lifestyle is of key importance for reduction of obesity and inflammation, as well as circulating levels of adipokines. Therefore, the aim of our study was to assess the relationship of physical fitness with chronic inflammatory status, and to ...

Species composition and distribution of gallinaceous birds (Aves, Galliformes) in the south of eastern Europe during the Late Pleistocene and Holocene—a review

open access: yesBoreas, EarlyView.
This study investigates the species composition and distribution of gallinaceous birds (Galliformes) in the south of eastern Europe, specifically within the territory of present‐day Ukraine, during the Late Pleistocene and Holocene. The research is based on the comprehensive revision of skeletal remains found at archaeological sites.

Implication of Barrier Fluctuations on the Rate of Weakly Adiabatic Electron Transfer

open access: yes, 2002
The problem of escape of a Brownian particle in a cusp-shaped metastable potential is of special importance in nonadiabatic and weakly-adiabatic rate theory for electron transfer (ET) reactions.

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

open access: yesBoreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Comparison theorems for the position-dependent mass Schroedinger equation

open access: yes, 2011
The following comparison rules for the discrete spectrum of the position-dependent mass (PDM) Schroedinger equation are established. (i) If a constant mass $m_0$ and a PDM $m(x)$ are ordered everywhere, that is either $m_0\leq m(x)$ or $m_0\geq m(x ...
