A laser system based on injection locking of a broad emitter diode laser operating at a wavelength of λ = 671 nm has been realized. With an injected power of 9.6 mW, 130 mW output power of the broad emitter diode laser is achieved. The broad emitter diode laser operates in a single spectral mode and its eigenmodes can be suppressed by more than 30 dB. By modulation of its operation current, sid...

Aneurysms Unruptured Aneurysms The first report of the International Study of Unruptured Intracranial Aneurysms (ISUIA) cited very low rates of subarachnoid hemorrhage (SAH) for previously unruptured aneurysms.1 Data were collected retrospectively. It was difficult to reconcile these rates with those reported from prior studies, with the known sizes of ruptured aneurysms and with clinical exper...

EGR1 encodes a transcription factor containing three zinc-finger (ZF) DNA-binding domains of the Cys2-His2 type. It is rapidly induced by variety extracellular stimuli and involved in multiple physiological processes, including apoptosis, cell proliferation, inflammation (Li et al., 2019Li T.T. Liu M.R. Pei D.S. Friend or foe, role EGR-1 cancer.Med Oncol. 2019; 37: 7Crossref PubMed Scopus (24) ...

Cereal Chem. 82(5):554-558 Field peas (Pisum salivum) were evaluated as a potential feedstock for ethanol production. Ground peas were dry-milled and separated into starch, protein, and fibrous fractions by air classification. Starch-enriched fractions prepared from whole peas and dehulled peas contained 73.717c wt and 77.8% wt starch, respectively, a nearly two-fold enrichment compared with wh...

The representative fraction, the metric traditionally used by cartographers to characterize the level of geographic detail in a map, is not well defined for digital geographic data. Increasingly complex and unsatisfactory conventions are needed to preserve this legacy of earlier technology. A series of requirements is defined for replacement metrics. For digital representations of fields, six c...

Conceptualizations of organic matter (OM) degradation are diverging within and among the soil, freshwater, marine subdisciplines.There is a need to step back from conceptualizations specific certain ecosystems holistically understand what controls OM, regardless ecosystem.Ecosystem properties changing rapidly due anthropogenic stressors, we encourage development conceptual earth system models b...

uring a recent excavation of a common grave on the outskirts of el-Qantir, Egypt, a human skeleton, mummified cat and vase from the First Intermediate Period of the Eleventh Dynasty were discovered. Based on similar findings in the surrounding area, the human skeleton was surmised to be a mummy, decomposing because of water from a nearby irrigation system. Carbon dating concluded the archaeolog...

Lepidoptera may acquire damage to their wings throughout their lifespan. The ability to quantify the accumulated damage is relevant when studying the impact of wing damage on territorial behavior, mating systems, predation, or assessing relative age of the insect, but unfortunately, methods for accurate insect wing damage quantification are scarce. The purpose of this paper is to introduce a ne...

Using a sample of 227 million Υ (4S) → BB events collected with the BABAR detector at the PEP-II B Factory in 1999–2004, we study B → D0 K (892) decays where K → K0 S π and D0 → K π+, K π+ π0, K π+ π+ π (non-CP final states), K+K−, π+ π (CP+ eigenstates), K0 S π0, K0 S φ and K0 S ω (CP− eigenstates). The partial rate charge asymmetries ACP and the ratios RCP defined in the literature as the sum...
