We present a measurement of the spectral index of density fluctuations between ion and electron scales in solar wind turbulence using the EFI instrument on the ARTEMIS spacecraft. The mean spectral index at 1 AU was found to be -2.75±0.06, steeper than predictions for pure whistler or kinetic Alfvén wave turbulence but consistent with previous magnetic field measurements. The steep spectra are ...

The amino-terminal domain of cardiac troponin C (cNTnC) is an essential Ca(2+) sensor found in cardiomyocytes. It undergoes a conformational change upon Ca(2+) binding and transduces the signal to the rest of the troponin complex to initiate cardiac muscle contraction. Two classical EF-hand motifs (EF1 and EF2) are present in cNTnC. Under physiological conditions, only EF2 binds Ca(2+); EF1 is ...

We study the problem of fair division when resources contain both divisible and indivisible goods. Classic fairness notions such as envy-freeness (EF) up to one good (EF1) cannot be directly applied mixed goods setting. In this work, we propose a new notion for (EFM), which is direct generalization EF EF1 prove that an EFM allocation always exists any number agents. also efficient algorithms co...

I argue that that contemporary set theory, as depicted in the 20112012 EFI lecture series, lacks a program that promises to decide, in a genuinely realist fashion, the continuum hypothesis (CH) and related questions about the “width” of the universe. We can distinguish three possible objectives for a realist completion of set theory: maximizing structures, maximizing sets, and maximizing interp...

Calcium-binding protein 1 (CaBP1) regulates inositol 1,4,5-trisphosphate receptors (InsP(3)Rs) and a variety of voltage-gated Ca(2+) channels in the brain. We report complete NMR chemical shift assignments of the Ca(2+)-saturated form of CaBP1 with Ca(2+) bound at EF1, EF3 and EF4 (residues 1-167, BMRB no. 16862).

Skeletal (RyR1) and cardiac muscle (RyR2) isoforms of ryanodine receptor calcium channels are inhibited by millimollar Ca(2+), but the affinity of RyR2 for inhibitory Ca(2+) is ~10 times lower than that of RyR1. Previous studies demonstrated that the C-terminal quarter of RyR has critical domain(s) for Ca(2+) inactivation. To obtain further insights into the molecular basis of regulation of RyR...

We study the problem of fair and efficient allocation a set indivisible chores to agents with additive cost functions. consider popular fairness notion envy-freeness up one good (EF1) efficiency Pareto-optimality (PO). While it is known that EF1+PO allocations exists can be computed in pseudo-polynomial time case goods, same open for chores. Our first result strongly polynomial-time algorithm c...

Safflower (Carthamus tinctorius L.) has received a significant amount of attention as a medicinal plant and oilseed crop. Gene expression studies provide a theoretical molecular biology foundation for improving new traits and developing new cultivars. Real-time quantitative PCR (RT-qPCR) has become a crucial approach for gene expression analysis. In addition, appropriate reference genes (RGs) a...

In Turkey, sweet chestnut, Castanea sativa, is an important species cultivated for wood, tannin and edible nuts. A nut disease was observed on chestnut trees located in the Western Black Sea region of Turkey (40°47′47.92″N-31°20′22.34″E). Symptoms were 19 out 100 nuts collected surveyed area (c. 1–2 ha) October 2021. The casual pathogen isolated from a diseased with brown discolouration (Fig. 1...
