Optical orthogonal codes obtained from conics on finite projective planes

AbstractOptical orthogonal codes can be applied to fiber optical code division multiple access (CDMA) communications. In this paper, we show that optical orthogonal codes with auto- and cross-correlations at most 2 can be obtained from conics on a finite projective plane. In addition, the obtained codes asymptotically attain the upper bound on the number of codewords when the order q of the base field is large enough

Can the Arts Change the World? The Transformative Power of the Arts in Fostering and Sustaining Social Change

A group of nonprofit leaders working in the arts, advocacy, political organizing, social services, and education explored the connection between community organizing and creative expression by engaging in collective activities, including visiting various examples of community arts, and experimentation with their own practice. Through this process, the group concluded that arts could be socially transformative; that community arts can create a safe space that allows people to trust and be open to changing; that art can help people reflect together and not talk past one another; and that the process of creating together can be healing and sustaining

A Case of Lipoma in the Deep Part of Neck

It is comparatively rare that lipoma is found in the deep part of neck, though lipoma is often found in parts of back, neck, breast, etc. And so the authors reported a case of lipoma in 71-year-old woman that was made the diagnosis of lipoma in the deep part of neck, from the clinical symptoms and CT examination, and was confirmed histologically after the enucleation under general anesthesia

The effects of perilla seed oil ointment for atopic dermatitis

近年アトピー性皮膚炎が増加しており,工ゴマ油を使った食事療法がアレルギー抑制に有用であることが報告されている｡そこで今回,エゴマ油を外用剤として使用するため,亜鉛華単軟膏を基剤とした工コマ軟膏を作製し,アトピー性皮膚炎患者3例を対象にその臨床応用を試みた｡その結果,掻痒感の軽減に効果がみられ,また皮膚症状では,丘疹.表皮剥離,苔癬化,落屑などの所見が改善される傾向が見られた｡The perilla seed oil contains rich α-linolenic acid (α-LNA), parent n-3 fatty acid. The dietary intake of n-3 fatty acid, such as perilla seed oil, has been reported to have some clinical effects in patients with allergic disease. In this report, we prepared the perilla seed oil ointment for atopic dermatitis and the effects of the ointment was evaluated in three patients with atopic dermatitis. This ointment suppressed skin itch, and improved papules, excoriation, lichenification and desquamation of the skin. These results suggest that the perilla seed oil ointment has some effectiveness including suppression of inflammatory changes of the skin in patients with atopic dermatitis

MutuallyM-intersecting Hermitian Varieties

AbstractLetMbe a set of integers. We consider a set of varieties in PG(n,q) such that each variety containsρpoints and the intersection of two distinct varieties containsμpoints, whereμ∈M. Such a set is called a set of mutuallyM-intersecting varieties. In this paper, it is shown that there exist new sets of mutuallyM-intersecting varieties by using Hermitian varieties in PG(2,q2)

Conditional Difference Asymmetry Model for Square Contingency Tables with Nominal Categories

This paper proposes a model, which is an extension-of-symmetry model, for square contingency tables with the same nominal row and column classifications. The model states that the absolute values of difference between the conditional probability that an observation will fall in cell (i, j) on condition that it falls in cell (i, j) or (j, i) and the conditional probability that it falls in cell (j, i) on the same condition, are constant for every i≠j. The model describes a structure of asymmetry (not symmetry), and it is applied to the data on a nominal scale. An example is given.Asymmetry, conditional distribution, nominal category, model, square table, symmetry,
