چکیده
In this paper, necessary and sufficient conditions are stated for the Craig-Sakamoto equation det(I − sA − tB) = det(I − sA)det(I − tB) to hold for all scalars s, t ∈ C. Moreover, spectral properties for matrices A and B that satisfy this equation are investigated.

Early life adversity is associated with a smaller hippocampus in male but not female depressed in-patients: a case–control study
BACKGROUND Three studies assessed the association of early life adversity (ELA) and hippocampal volumes in depressed patients, of which one was negative and the two others did not control for several potential confounding variables. Since the association of ELA and hippocampal volumes differ in male and female healthy volunteers, we investigated the association of ELA and hippocampal volumes in...
متن کاملتعیین ارتفاع خط تعادل (ELA) در دره‌ی هراز در آخرین دوره‌ی یخچالی
گسترش و بسط نظریه‌ی یخبندان کواترنری به وسیله‌ی تجزیه و تحلیل داده‌ها و یافتن ارتباط میان جهت و ارتفاع ناهمواری و چگونگی پدید آمدن اشکال مورفولوژی یخچالی هدفی است که این تحقیق بنیادی در تلاش برای نیل به آن است. بر این اساس، اهداف فرعی زیر مطرح می‌شوند: الف) شناخت اشکال مورفولوژی یخچالی در دره‌ی هراز؛ و ب) تعیین مرزهای یخچالی کواترنری در البرز مرکزی. دره‌ی هراز، از دامنه‌ی آزادکوه تا دره‌ی اصلی ...
متن کاملImproved erythrocyte lysis assay in microtitre plates for sensitive detection and efficient measurement of haemolytic compounds from ichthyotoxic algae.
Haemolytic substances produced by ichthyotoxic algae often are unknown in molecular structure or specific mechanism of toxicity. Detection and quantification of such substances are dependent on bioassays, using markers that are sensitive for haemolytic impairment and generation of a recordable response. The erythrocyte lysis assay (ELA) represents an advantageous bioassay in this respect, becau...
متن کاملMap-based methods for estimating glacier equilibrium-line altitudes
We examine the validity of two methods for estimating glacier equilibrium-line altitudes (ELAs) from topographic maps. The ELA determined by contour inflection (the kinematic ELA) and the mean elevation of the glacier correlate extremely well with the ELA determined from mass-balance data (observed ELA). However, the range in glacier elevations above sea level is much larger than the variation ...
متن کاملEquilibrium-Line Altitudes of Late Quaternary Glaciers in the Zardkuh Mountain, Iran
Equilibrium-line altitudes (ELAs) of former glaciers in the Zardkuh Mountain of the Zagros Mountain Range were reconstructed from glacial-geologic data on former ice limits by using various methods. In the study area various types of glacial landforms such as outwash fans, moraines and well developed glacial cirques are observed. The results suggest that ELA were depressed 1433 m below to prese...
متن کاملElabela-Apelin Receptor Signaling Pathway is Functional in Mammalian Systems
Elabela (ELA) or Toddler is a recently discovered hormone which is required for normal development of heart and vasculature through activation of apelin receptor (APJ), a G protein-coupled receptor (GPCR), in zebrafish. The present study explores whether the ELA-APJ signaling pathway is functional in the mammalian system. Using reverse-transcription PCR, we found that ELA is restrictedly expres...
