Sickle cell hemoglobin is a β chain structural variant where valine is substituted for glutamic acid in the sixth amino acid position. A point mutation (A--->T) in codon 6 of the β globin gene which is located on the short arm of chromosome 11 is responsible for this abnormality. Despite the fact that all sickle cell disease patients have an identical single base change in their DNA, the severi...
Direct and resolved photon interactions are shown to be intimately related through the factorization mechanism. It is argued that in theoretically consistent analysis of jet production in γp and ep collisions the LO resolved γ contribution must be considered together with the NLO direct γ component. Recent data from HERA therefore do not provide a direct evidence for the former component, but s...
ing d = f · b. Conversely, if this homomorphic condition holds everywhere, then apply b to both its sides, observe that Cχb = iA and by abstracting c get h = Cχa with a = h · b. Q.D.E. 5.8 Definitions. Keep the notation of 5.4 and let B be the set of bases of α with index X. Consider a family k: B → F(FXA)C, for some C, and a b ∈ B. If for all b′ ∈ B and M :X → A (43) kbM = kb′(M ◦ b′) , then w...
Since the work of Gauss, number theorists have been interested in analogues of Z where concepts from arithmetic can also be developed. The example we will look at in this handout is the Gaussian integers: Z[i] = {a + bi : a, b ∈ Z}. Excluding the last two sections of the handout, the topics we will study are extensions of common properties of the integers. Here is what we will cover in each sec...
Sleep is considered an important predictor of immunity. A lack of sleep may reduce immunity, which increases susceptibility to any type of infection. Moreover, sleep deprivation in humans produces changes in both, the percent of circulating immune cells (T cells and NK cells) and cytokine levels (IL-1, IFNγ, TNΦ-αα, IL-6 and IL-17). The aim of our study was to investigate whether sleep deprivat...
S100 proteins are acidic low molecular weight members of a family of calcium-binding proteins that were originally identified in the nervous system [1,2], S100 proteins have since been localized to several neuronal and non-neuronal cells, including adrenal chromaffin cells and skeletal muscle cells, in addition to glial cells and neurons [3]. The two “classic” S100 proteins were given the desig...
In the framework of the model motivated by perturbative calculations in the fourth O(α 3 s α)-order, the estimates for the γp cross-section of the D *-meson production in the ZEUS experiment are performed. We factorize the hadronization of (c¯ q)-state hardly produced in perturbative QCD, which allows us to take into account the higher twist terms in the powers of 1/p T at p T ∼ m c and to corr...

The rare isotope Li is made only by cosmic rays, dominantly in αα → Li fusion reactions with ISM helium. Consequently, this nuclide provides a unique diagnostic of the history of cosmic rays in our Galaxy. The same hadronic cosmic-ray interactions also produce high-energy γ rays (mostly via pp → π → γγ). Thus, hadronic γ-rays and Li are intimately linked. Specifically, Li directly encodes the l...
