We show how the generation of a lepton number in the Early Universe induced by να ↔ νs, in presence of small baryon number inhomogeneities, gives rise to the formation of lepton domains. The structure of these domains reflects the spectral features of the baryon number inhomogeneities that generated it and interestingly the size of the lepton domains can be super-horizon. PACS numbers: 14.60.Pq...

In this paper we look into the problem of planning over hybrid domains, where change can be both discrete and instantaneous, or continuous over time. In addition, it is required that each state on the trajectory induced by the execution of plans complies with a given set of global constraints. We approach the computation of plans for such domains as the problem of searching over a deterministic...

Drosophila oogenesis starts when a germline stem cell divides asymmetrically to generate a daughter germline stem cell and a cystoblast that will develop into a mature egg. We show that the fs(1)Yb gene is essential for the maintenance of germline stem cells during oogenesis. We delineate fs(1)Yb within a 6.4 kb genomic region by transgenic rescue experiments. fs(1)Yb encodes a 4.1 kb RNA that ...

Transfer learning can address the tasks of unlabeled data in target domain by leveraging plenty labeled from a different but related source domain. A core issue transfer is to learn shared feature space where distributions two domains are matched. This process be named as representation (TRL). Feature transformation methods crucial ensure success TRL. The most commonly used method TRL kernel-ba...

Vibrational sum-frequency generation (vSFG) measurements in the frequency and time domains reveal that the interfacial hydrogen bonded OH stretch at the water/calcium fluoride interface is composed of two populations oriented oppositely. The time-resolved vSFG free-induction decay suggested that, whereas the strongly hydrogen bonded OH vibrational stretches, centered near 3140 ± 11 cm-1, are or...

We present an RF gun design for single shot ultrafast electron diffraction experiments that can produce sub-100 fs high-charge electron bunches in the 130 keV energy range. Our simulations show that our proposed half-cell RF cavity is capable of producing 137 keV, 27 fs rms (60 fs FWHM), 106 electron bunches with an rms spot size of 276 μm and a transverse coherence length of 2.0 nm. The requir...

Background: Alteration in the protein signatures of functionally immature testicular spermatozoa occurs during their journey through the epididymis. This leads to acquisition of sperm domain specific functions essential for successful fertilization. Epididymal sperm proteins are preferred targets for immunocontraception as well as in elucidating the causes of infertility. The Background of the ...

We introduce the Fourier-Stieltjes algebra in Rn which we denote by FS(Rn). It is a subalgebra of the algebra of bounded uniformly continuous functions in Rn, BUC(Rn), strictly containing the almost periodic functions, whose elements are invariant by translations and possess a mean-value. Thus, it is a so called algebra with mean value, a concept introduced by Zhikov and Krivenko (1986). Namely...

a 42-day study was conducted to evaluate the influence of full-fat flaxseed (fs) and canola seed (cs) on broiler performance, fatty acid (fa) profile of meat, serum lipid content and antibody response to sheep red blood cells antigen (srbc). a total of 324 one-day-old chicks were attributed to 6 experimental groups. c: control (soybean-corn); cs1:7.5% cs; cs2:15% cs; cs-fs:10% fs + 10% cs; fs1:...
