Public concern about the welfare of hens kept in conventional cages has become an important issue worldwide. This study examined the effects of conventional cages (CC) and floor pens (FP) on hens’ health and egg production. A total of 84 19-wk-old Bovan Brown hens were randomly assigned into 2-bird cage (n = 12), providing 968 cm2 floor space per hen or 10-bird floor pens (n = 6), providing 371...

In this paper, we propose an online clustering method called Contrastive Clustering (CC) which explicitly performs the instance- and cluster-level contrastive learning. To be specific, for a given dataset, positive negative instance pairs are constructed through data augmentations then projected into feature space. Therein, learning respectively conducted in row column space by maximizing simil...

Let K be a convex cone in a real Banach space. The main purpose of this paper is to show that for a regular cosine family {Ft : t ∈ R} of linear continuous multifunctions Ft : K → cc(X) there exists a linear continuous multifunction H : K → cc(K) such that Ft(x) ⊂ ∞ X n=0 t (2n)! H(x). Let X be a real normed vector space. We will denote by n(X) the family of all nonempty subsets of X and by cc(...

In this work, we perform a systematic study of the mass spectra, root mean square(r.m.s.) radii and radial density distributions doubly charmed baryons $\Xi_{cc}$ $\Omega_{cc}$. The calculations are carried out in frame work Godfrey-Isgur (GI) relativized quark model, where baryon is regarded as real three-body system quarks. Our results show that excited energy with $\rho$-mode lower than thos...

We prove an optimal Hardy inequality for the fractional Laplacian on the half-space. 1. Main result and discussion Let 0 < α < 2 and d = 1, 2, . . .. The purpose of this note is to prove the following Hardy-type inequality in the half-space D = {x = (x1, . . . , xd) ∈ R : xd > 0}. Theorem 1. For every u ∈ Cc(D), (1) 1 2 ∫

In 1990 Subramanian de ned the complexity class CC as the set of problems log-space reducible to the comparator circuit value problem (Ccv). He and Mayr showed that NL⊆CC⊆P, and proved that in addition to Ccv several other problems are complete for CC, including the stable marriage problem, and nding the lexicographically rst maximal matching in a bipartite graph. Although the class has not rec...

Let X be a nonempty compact subset of a Banach space (E,‖·‖), and let C(X) and CC(X) denote the families of all nonempty compact and all nonempty compact convex subsets of X , respectively. It is well known that (C(X),H) is compact, where H is the Hausdorff metric induced by ‖·‖. For A,B ∈ CC(X) and t ∈ R = (−∞,+∞), let A + B = {a + b : a∈ A, b ∈ B}, and let tA= {ta : a∈ A}. In the sequel, we a...

Weak protein interactions between ubiquitin and the ubiquitin-proteasome system (UPS) enzymes that mediate its covalent attachment to substrates serve to position ubiquitin for optimal catalytic transfer. We show that a small-molecule inhibitor of the E2 ubiquitin-conjugating enzyme Cdc34A, called CC0651, acts by trapping a weak interaction between ubiquitin and the E2 donor ubiquitin-binding s...
