Published: December 2019

Abstract
This study aimed to investigate how to teach the surface area of a sphere and volume of a ball to students of elementary school teacher education using the inquiry approach. The study used a single-subject research approach for students of elementary school teacher education, Universitas Kanjuruhan Malang, Indonesia, who have been permanent teachers in elementary schools. They were to teach the surface area of the volume using experimental demonstration method. The data analysis used in this study was a combination of quantitative and qualitative description. The results of the study showed that students found the surface area of a sphere was 4πr^2using the approach of circle area and the volume of a ball was 4/3 πr^3 using the approach of a cylinder volume. It had been proven that the approach was effective to improve students’ understanding, particularly on the surface area and the volume. In addition, they were also able to implement it to their students at schools.
Development of rental property insurance models with Generalized Linear Models (GLM)
Authors: Sudarwanto S , Ambarwati L , Hadi I 
Published: December 2019

Abstract
In this paper we developed insurance model on property rental business using. Generalized Linear Models (GLM). GLM was chosen because the data on property rental match with the characteristics of GLM. Analysis of the model is done by looking at the relationship between the distribution functions that are most widely used in the analysis of property rental data. The models for the relations of distribution functions are: Poisson-Gamma, Poisson-Inverse Gauss, Negative Binomial-Gamma and Negative Binomial-Inverse Gauss. The relationship between the distributions is seen from the root-mean-squared error (RMSE) and absolute mean error (MAE). The simulation results show that the model formed in the case of random effects increases in standard deviation values also increases the variation value on the average estimator. This is in accordance with the condition that the addition of standard deviation means that there is an increase in the variance of the data.

Authors: Yasa A D , Chrisyarani D D , Utama D M , Werdiningtiyas R K 
Published: December 2019

Abstract
Teaching performance evaluation is an important factor to improve the quality of teaching as well as the quality of school management. This paper aimed to evaluate teaching performance in elementary schools. Since Information and Communication Technology (ICT) support is one of the multi criteria of evaluation, AHP and SAW integration was suggested to evaluate teaching performance. In the evaluation process, AHP method was used to consider criteria and sub-criteria. Therefore, a case study was conducted to describe the issue. The results showed that both the methods of AHP and SAW were objective, accurate, and scientific in evaluating elementary school teachers’ teaching performance. It is expected that the tool is used to be able to improve teaching performance in elementary schools.
Wreath products and multipartite quantum systems
Authors: Kornyak Vladimir V 
Published: December 2019

Abstract
A natural symmetry group of a multicomponent quantum system is a special combination of a symmetry group acting within a single component (“local group”) and a group that permutes the components (“spatial symmetry group”). This combination is called the wreath product. Unitary representations of wreath products describe quantum evolutions of multipartite systems. It is known that any unitary representation of a finite group is contained in some permutation representation. We describe an algorithm for decomposing permutation representations of wreath products into irreducible components. This decomposition makes it possible to study the quantum behavior (entanglement, non-local correlations, etc.) of multipartite systems in invariant subspaces of the permutation Hilbert space.
Vaisman Algebroid and Doubled Structure of Gauge Symmetry in Double Field Theory
Authors: Mori Haruka , Sasaki Shin , Shiozawa Kenta 
Published: December 2019

Abstract
The Vaisman algebroid is a kind of algebroid structure. It is de ned by an extension of the Courant algebroid, and phisically related to the gauge symmetry in Double Field Theory (DFT), which is an effective theory of string theory. DFT has T-duality as a manifest symmetry. In this study, we focus on the \doubled structure” in the Vaisman algebroid. It is already well known that some kind of Lie algebras are obtained by the Drinfel’d double of Lie bialgebras. The Courant algebroid is obtaind by the Drinfel’d double of Lie bialgebroids. We nd that the Vaisman algebroid can be obtained by an analogue of the \Drinfel’d double” of Lie algebroids. We discuss the algebraic origin of the strong constraint in DFT.

Authors: Ongong’a Elvice , Richter Johan , Silvestrov Sergei 
Published: December 2019

Abstract
We describe the dimension of the space of possible linear endomorphisms that turn skew-symmetric three-dimensional algebras into Hom-Lie algebras. We find a correspondence between the rank of a matrix containing the structure constants of the bilinear product and the dimension of the space of Hom-Lie structures. Examples from classical complex Lie algebras are given to demonstrate this correspondence.
Integrable surfaces induced by generalized Landau-Lifshitz equation with self-consistent potential
Authors: Sagidullayeva Zh. , Nugmanova G. , Myrzakulov R. 
Published: December 2019

Abstract
In this paper, we present integrable surfaces associated with generalized LandauLifshitz equation with self-consistent potential. We obtained the rst and second fundamental forms. The rst fundamental form allow us to calculate the curvature and metric properties of a surface, particularly, length and area of related space. The second fundamental form determines the external geometry of the surface in the vicinity of this point. Together they permit to de ne extrinsic invariants of the surface and its principal curvatures. The results can be used to describe spin waves in magnets and ferromagnets.

Para-Hermitian Geometry and Doubled Aspects of Vaisman Algebroid
Authors: Shiozawa Kenta 
Published: December 2019

Abstract
The geometry of double field theory (DFT) is described by a para-Hermitian manifold M. A tangent bundle of the para-Hermitian manifold T M is decomposed into two eigenbundles L and ∼L associated with the eigenvalues of the para-complex structure K. We define a Lie algebroid structure on the eigenbundles L, ∼L. The gauge symmetry algebra of DFT is governed by the C-bracket. The algebraic structure based on the C-bracket is not a Courant algebroid, but a metric algebroid proposed by Vaisman (the Vaisman algebroid). We show that the Vaisman algebroid in DFT is naturally defined on T M by an analogue of the Drinfel’d double of L, ∼L. We also find that an algebraic origin of the strong constraint is the condition for (L, ∼L) to become a Lie bialgebroid.
Prime forms and higher genus deformed Eisenstein series
Authors: Zuevsky Alexander 
Published: December 2019

Abstract
Using the theory of Szegő kernel on a genus g Riemann surfaces obtained as a result of the multiple ρ-parameter formalism of sewing of g handles to the complex sphere, we derive new formulas related prime forms, theta functions, and deformed Eisenstein series. We establish recurrent formulas for genus g prime forms and Szegő kernel as well as further identities. Using the above results, we introduce finally another definition of genus g counterpart of genus one deformed Eisenstein series. The results obtained are then useful in computation of vertex algebra related cohomologies.
Critical role of V1a vasopressin receptor in murine parturition†
Authors: Tsuchiya Hiroyoshi , Fujimura Shyota , Fujiwara Yoko , Koshimizu Taka-aki 
Published: December 2019

Abstract
The precise mechanisms of the reproductive physiological processes, such as labor initiation, are poorly understood. Oxytocin (OT) is one of the well-known uterotonics and is clinically adopted as a medication to facilitate childbirth. Vasopressin (VP), a posterior pituitary hormone similar to OT, has also been proposed to be involved in the reproductive physiology. In this study, we found that a total deficiency of V1a receptor subtype (V1aR) in mice resulted in a reduced number of pups, delayed labor initiation, and increased post-delivery hemorrhage compared with those in wild-type mice. Among the VP receptor subtypes, only V1aR was found to be expressed in the murine uterus, and its distribution pattern was different from that of the oxytocin receptor (OTR); V1aR expression was mainly distributed in the circular myometrium, whereas OTR was strongly expressed in both the circular and longitudinal myometrium. The maximum contractile force of the circular myometrium, induced by VP or OT, was attenuated in the pregnant uterus of Avpr1a-deficient mice. Contrarily, while OT expression was decreased in the Avpr1a-deficient uterus, OTR expression was significantly increased. These results suggest that V1aR deficiency not only reduces the uterine contractile force but also perturbs the expression of genes responsible for the reproductive physiology. Therefore, V1aR is necessary to exert the maximum contraction of the circular myometrium to deliver pups. This study revealed an important role of V1aR in physiological contraction and term parturition in mice.
Loss of tyrosine kinase receptor Ephb2 impairs proliferation and stem cell activity of spermatogonia in culture†
Authors: N’Tumba-Byn Thierry , Yamada Makiko , Seandel Marco 
Published: December 2019

AbstractGermline stem and progenitor cells can be extracted from the adult mouse testis and maintained long-term in vitro. Yet, the optimal culture conditions for preserving stem cell activity are unknown. Recently, multiple members of the Eph receptor family were detected in murine spermatogonia, but their roles remain obscure. One such gene, Ephb2, is crucial for maintenance of somatic stem cells and was previously found enriched at the level of mRNA in murine spermatogonia. We detected Ephb2 mRNA and protein in primary adult spermatogonial cultures and hypothesized that Ephb2 plays a role in maintenance of stem cells in vitro. We employed CRISPR-Cas9 targeting and generated stable mutant SSC lines with complete loss of Ephb2. The characteristics of Ephb2-KO cells were interrogated using phenotypic and functional assays. Ephb2-KO SSCs exhibited reduced proliferation compared to wild-type cells, while apoptosis was unaffected. Therefore, we examined whether Ephb2 loss correlates with activity of canonical pathways involved in stem cell self-renewal and proliferation. Ephb2-KO cells had reduced ERK MAPK signaling. Using a lentiviral transgene, Ephb2 expression was rescued in Ephb2-KO cells, which partially restored signaling and proliferation. Transplantation analysis revealed that Ephb2-KO SSCs cultures formed significantly fewer colonies than WT, indicating a role for Ephb2 in preserving stem cell activity of cultured cells. Transcriptome analysis of wild-type and Ephb2-KO SSCs identified Dppa4 and Bnc1 as differentially expressed, Ephb2-dependent genes that are potentially involved in stem cell function. These data uncover for the first time a crucial role for Ephb2 signaling in cultured SSCs.
“They’re in My Heart, Mind, and Cells”: What Continuing Bonds Reveal About Social Networks
Authors: Stemen Sara E 
Published: December 2019

Abstract

Background and Objectives
Research suggests that robust social networks have positive effects on peoples’ well-being. An instrumental methodology for studying networks is the social convoy model, a diagram of concentric circles that illustrate network size, structure, and satisfaction. Convoys have been described as dynamic. Specifically, as people age, their convoys become stronger and smaller due to focusing on what matters most and accumulating losses. Therefore, convoys only include meaningful, living persons. The continuing bonds model posits that it is normal for people to maintain connections with the deceased. The objective of the current study was to integrate the social convoy and continuing bonds models in order to examine the presence of deceased loved ones in convoys.

Research Design and Methods
Eighteen individuals (M = 66 years), recruited via fliers and snowball sampling, participated in one semistructured interview regarding the death of a loved one and their convoy. Participants also completed a convoy model, identifying where the deceased fit (if anywhere) when they were alive and at present. Interviews were transcribed, coded, and analyzed for themes.

Results
Three themes emerged: communication (i.e., writing or speaking to the deceased), continuity (i.e., a continuing relationship), and reciprocity (i.e., perceived exchange of support(s)). Eighty-nine percent of participants felt their loved one’s death did not change their convoy presence and 88% reported that their positioning in the convoy remained unchanged.

Discussion and Implications
This research offers a new way to think about convoys and may prompt the development of supportive interventions for bereaved individuals.

Genetic parameter estimates for plasma oxidative status traits in slaughter pigs
Authors: Ntawubizi Martin , Raes Katleen , De Smet Stefaan 
Published: December 2019

AbstractThe aim of the present study was to assess the effect of sex and to estimate genetic parameters for several traits related to plasma oxidative status in slaughter pigs, i.e., ferric reducing ability of plasma (FRAP), concentrations of α-tocopherol and malondialdehyde (MDA), and glutathione peroxidase (GPx) activity. Blood samples were collected at slaughter from 477 Piétrain × (Landrace × Large White intercross) pigs of 2 performance test stations. Heritabilities (±SE) of plasma oxidative status traits as well as their phenotypic and additive genetic correlations with animal performance traits were estimated with multiple-trait REML animal models using VCE software. Results displayed no significant difference between barrows and gilts for FRAP and α-tocopherol in plasma. However, gilts had a significantly higher concentration of MDA and lower GPx activity compared with barrows. Heritability estimates were high for GPx (0.55 ± 0.05), and medium to low for α-tocopherol (0.30 ± 0.06), FRAP (0.22 ± 0.05), and MDA (0.15 ± 0.04). Estimated additive genetic and phenotypic correlations between these four traits were generally low, except for a negative additive genetic correlation between FRAP and GPx of −0.45 (±0.23). Additive genetic correlations between plasma oxidative status traits and animal performance traits were also generally absent or low with maximum values of ~0.3. Parameter estimates in this study have to be interpreted with caution because of the small size of the dataset. Nevertheless, it may be concluded that there is considerable additive genetic variance for plasma oxidative status traits in slaughter pigs. More research is warranted on the genetic determination of oxidative stress in farm animals and its relevance in breeding programs.
Identification of Volatiles From Plants Infested With Honeydew-Producing Insects, and Attraction of House Flies (Diptera: Muscidae) to These Volatiles
Authors: Hung Kim Y , McElfresh J Steven , Zou Yunfan , Wayadande Astri , Gerry Alec C 
Published: December 2019

AbstractHouse flies (Musca domestica L.) are mechanical vectors of food-borne pathogens including Salmonella spp., Escherichia coli O157:H7, and Shigella spp., resulting in increased risk of diarrheal disease in areas where flies are abundant. Movement of house flies into food crops may be increased by the presence of honeydew-producing insects feeding on these crops. Using gas chromatography-electroantennogram detection (GC-EAD) and gas chromatography-mass spectrometry (GC-MS), volatile odors that elicited house fly antennal response were identified from naval orange (Osbeck) (Sapindales: Rutaceae) and Marsh grapefruit (Macfad.) (Sapindales: Rutaceae) leaves infested with whitefly (Hemiptera: Aleyrodidae) and from whole faba (L.) (Fabales: Fabaceae) bean plants infested with aphids (Hemiptera: Aphididae). Volatiles identified included benzaldehyde, butyl hexanoate, β-caryophyllene, Δ3-carene, (E)-4,8-dimethyl-1,3,7-nonatriene (DMNT), (Z)-3-hexenyl acetate, myrcene, limonene, linalool, and naphthalene. This was followed by semifield bioassays of volatile blends and individual volatiles to determine house fly attraction to these volatiles. Although fly capture rates in the semifield setting were low, benzaldehyde and (Z)-3-hexenyl acetate were consistently attractive to house flies as individual compounds and as components of volatile blends.
