Jeon, ex barnacles. Distribution. Korea (South). Etymology. The adjective submarina refers to the microhabitat of the species. Remarks. There is sexual dimorphism in size (bigger in male) and shape of head (broadening anteriorly in male but more or less parallel in female) in this new species as other Diaulota species (Fig. 1A). This species is similar to D. uenoi and almost indistinguishable by the external morphological characters (see key couplet below). However, it is different from the latter in mouthparts and the external shape and internal structure of the median lobe. Apical process of D. uenoi is broader and more abruptly bent upward (fig. 10L in Sawada, 1971) compared to the new species, narrower and slightly bent upward (Fig. 4D; fig. 40 in Ahn, 1996). Especially, the form of internal sclerites of median lobe are different: apical one larger and polygonal in D. submarina (Fig. 4D; fig. 40 in Ahn, 1996) but smaller and rounded in D. uenoi (fig. 10L in Sawada, 1971). They can be regarded as cryptic species.Published as part of Ahn, Kee-Jeong, 2023, Description of Diaulota submarina sp. nov.

Study on Λ6H hypernucleus by the (π−, K+) reaction at J-PARC
We carried out an experiment to produce the neutron-rich hypernucleus Λ6H via the (π−, K+) reaction on 6Li target at the pion beam momentum of 1.2 GeV/c (J-PARC E10). In order to calibrate the scale of the missing-mass or of the Λ binding energy of the hypernucleus, we also measured the 12C(π+, K+) Λ12C, p(π−, K+)Σ− and p(π+, K+)Σ+reactions. The experiment was performed at the J-PARC Hadron Hall K1.8 beam line in December 2012 and January 2013. The overall collected data sample corresponds to an integrated beam intensity of 1.65 × 1012 pions

Realistic roofs without local minimum edges over a rectilinear polygon
Computing all possible roofs over a given ground plan is a common task in automatically reconstructing a three dimensional building. In 1995, Aichholzer et al. proposed a definition of a roof over a simple polygon P in the xy-plane as a terrain over P whose faces are supported by planes containing edges of P and making a dihedral angle ��/4 with the xy-plane. This definition, however, allows roofs with faces isolated from the boundary of P and local minimum edges inducing pools of rainwater. Very recently, Ahn et al. introduced ��realistic roofs�� over a rectilinear polygon with n vertices by imposing two additional constraints under which no isolated faces and no local minimum vertices are allowed. Their definition is, however, restricted and excludes a number of roofs with no local minimum edges. In this paper, we propose a new definition of realistic roofs over a rectilinear polygon that corresponds to the class of roofs without isolated faces and local minimum edges. We investigate the geometric and combinatorial properties of realistic roofs and show that the maximum possible number of distinct realistic roofs over a rectilinear n-gon is at most 1.3211m(m?m/2?), where m=(n?4)/2. We also present two algorithms that generate all realistic roofs. ? 2017 Elsevier B.V.11sciescopu
Violation of Rotational Invariance of Local Realistic Models with Two Settings
We have considered a two-particle Bell experiment to visualize the conflict between rotational invariance of physical laws and a specific local realistic theory. The experiment is reproducible by using a local realistic theory obtained in a two-setting Bell experiment. The generalized Bell inequality [J. Phys. A: Math. Theor. 40, 13101 (2007)], which is derived under the assumption that there exists a rotationally invariant local realistic theory, turns out to disprove such a local realistic model existing with a two-setting experiment. This implies that such a model is riot rotationally invariant and should, therefore, be ruled out in some situations.This work has been supported by Frontier Basic Research Programs at Korea Advanced Institute of Science and Technology.
