Abstract
Objective There is increasing interest in investigating the utility of 7 Tesla (7 T) magnetic resonance imaging (MRI) for imaging of skull base tumors. The present study quantifies visualization of tumor features and adjacent skull base anatomy in a homogenous cohort of pituitary adenoma patients.
Methods Eighteen pituitary adenoma patients were scanned at 7 T in this prospective study. All patients had reference standard-of-care clinical imaging at either 3 T (7/18, 39%) or 1.5 T (11/18, 61%). Visualization of tumor features and conspicuity of arteries and cranial nerves (CNs) was rated by an expert neuroradiologist on 7 T and clinical field strength MRI. Overall image quality and severity of image artifacts were also characterized and compared.
Results Ability to visualize tumor features did not differ between 7 T and lower field MRI. Cranial nerves III, IV, and VI were better detected at 7 T compared with clinical field strength scans. Cranial nerves III, IV, and VI were also better detected at 7 T compared with only 1.5 T, and CN III was better visualized at 7 T compared with 3 T MRI. The ophthalmic arteries and posterior communicating arteries (PCOM) were better detected at 7 T compared with clinical field strength imaging. The 7 T also provided better visualization of the ophthalmic arteries compared with 1.5 T scans.
Conclusion This study demonstrates that 7 T MRI is feasible at the skull base and identifies various CNs and branches of the internal carotid artery that were better visualized at 7 T. The 7 T MRI may offer important preoperative information that can help to guide resection of pituitary adenoma and reduce operative morbidity.

Published: November 2019

ABSTRACT
Kuji amber is fossilized tree resin of the Late Cretaceous in Japan. In this study, new biological activities of ethanol extract of Kuji amber (EtOH ext.) and supercritical carbon dioxide fluid extract of Kuji amber (scCO2 ext.) were examined. Both EtOH ext. and scCO2 ext. inhibited melanin production in B16 mouse melanoma cells and promoted collagen production in human skin fibroblast SF-TY cells. The scCO2 ext. had more potent activity than that of EtOH ext. and may depend on the efficiency of the extraction. The main new biologically active compound in Kuji amber, kujigamberol had no activities against melanin production, however, it promoted collagen production at low concentrations. A biologically active compound having a different structure, spirolactone norditerpenoid, showed both the inhibition activity against melanin production and the promotion activity of collagen production in a dose dependent manner. EtOH ext. and scCO2 ext., which include both kujigamberol and spirolactone norditerpenoid, have not only anti-allergy activity, but also inhibit melanin production and promote collagen production.
One-way steering of the optical fields with respect to the low-Q cavity via the thermal noise
Authors: Zhong Wenxue , Cheng Guangling , Hu Xiangming 
Published: November 2019

Abstract
We show that thermal noise could play a positive role in generating one-way Einstein–Podolsky–Rosen (EPR) steering of two cavity fields dispersively interacting with a single four-level atom, each of which is independently coupled to a thermal reservoir. In the low-Q and weak Raman transition regimes, two output fields exhibit asymmetric EPR steering and the steering direction could be easily controlled by adjusting the mean photon numbers of the thermal reservoirs and the decay rates of cavities. Striking features are present in our scheme. First, one-way EPR steering is achieved by using the couplings of the cavities with the heat baths, which sheds light on the quantum state manipulation in the presence of decoherence. Second, the obtainable EPR steering occurs between the cavity fields in the low-Q regime, which relaxes the constraints on the use of good cavities and so makes our scheme more practical. Third, the correlation properties of the output modes are considered, which can be measured more conveniently and will be more applicable to implement a range of quantum information processing.

Differential and angle-integrated cross sections for the 10B(n, α)7Li, 10B(n, α
0) 7Li and 10B(n, α
1) 7Li* reactions have been measured at CSNS Back-n white neutron source. Two enriched (90%) 10B samples 5.0 cm in diameter and ~85.0 μg/cm2 in thickness each with an aluminum backing were prepared, and back-to-back mounted at the sample holder. The charged particles were detected using the silicon-detector array of the Light-charged Particle Detector Array (LPDA) system. The neutron energy En
was determined by TOF (time-of-flight) method, and the valid α events were extracted from the En
-Amplitude two-dimensional spectrum. With 15 silicon detectors, the differential cross sections of α-particles were measured from 19.2° to 160.8°. Fitted with the Legendre polynomial series, the (n, α) cross sections were obtained through integration. The absolute cross sections were normalized using the standard cross sections of the 10B(n, α)7Li reaction in the 0.3 – 0.5 MeV neutron energy region. The measurement neutron energy range for the 10B(n, α)7Li reaction is 1.0 eV≤En
< 2.5 MeV (67 energy points), and that for the 10B(n, α
0) 7Li and 10B(n, α
1) 7Li* reactions is 1.0 eV ≤ En
< 1.0 MeV (59 energy points). The present results have been analyzed by the resonance reaction mechanism and the level structure of the 11B compound system, and compared with existing measurements and evaluations.
Possibilities of producing superheavy nuclei in multinucleon transfer reactions based on radioactive targets *
Authors: Zhu Long 
Published: November 2019

Abstract
The multinucleon transfer (MNT) process has been proposed as a promising approach to produce neutron-rich superheavy nuclei (SHN). MNT reactions based on the radioactive targets 249Cf, 254Es, and 257Fm are investigated within the framework of the improved version of a dinuclear system (DNS-sysu) model. The MNT reaction 238U + 238U was studied extensively as a promising candidate for producing SHN. However, based on the calculated cross-sections, it was found that there is little possibility to produce SHN in the reaction 238U + 238U. In turn, the production of SHN in reactions with radioactive targets is likely.
Nuclear mass parabola and its applications *

Published: November 2019

Abstract
We propose a method for extracting the properties of the isobaric mass parabola based on the total double

-decay energies of isobaric nuclei. Two important parameters of the mass parabola, the location of the most

-stable nuclei

and the curvature parameter

, are obtained for 251 A values, based on the total double

-decay energies of nuclei compiled in the AME2016 database. The advantage of this approach is that the pairing energy term

caused by the odd-even variation can be removed in the process, as well as the mass excess

of the most stable nuclide for the mass number A, which are employed in the mass parabolic fitting method. The Coulomb energy coefficient

MeV is determined by the mass difference relation for mirror nuclei, and the symmetry energy coefficient is also studied by the relation

The structure of neutron-rich calcium isotopes studied by the shell model with realistic effective interactions *
Authors: Wang Xiao-Bao , Meng Yu-Hang , Tu Ya , Dong Guo-Xiang 
Published: November 2019

Abstract
We study the structure of neutron-rich calcium isotopes in the shell model with realistic interactions. The CD-Bonn and Kuo-Brown (KB) interactions are used. As these interactions do not include the three-body force, their direct use leads to poor results. We tested whether the adjustment of the single particle energies (SPEs) would be sufficient to include the three-body correlations empirically. It turns out that the CD-Bonn interaction, after the adjustment of SPEs, gives good agreement with the experimental data for the energies and spectroscopy. For the KB interaction, both the SPEs and monopole terms require adjustments. Thus, the monopole problem is less serious for modern realistic interactions which include perturbations up to the third order. We also tested the effect of the non-central force on the shell structure. It is found that the effect of the tensor force in the CD-Bonn interaction is weaker than in the KB interaction.
Is X(3872) a bound state? *
Authors: Ortega Pablo G. , Arriola Enrique Ruiz 
Published: November 2019

Abstract
All existing experimental evidence for the bound state nature of

relies on observing its decay products, which are measured with a finite experimental mass resolution that is typically

MeV , and much larger than its alleged binding energy,

MeV. On the other hand, we have found recently that there is a clear cancellation in the

channel of the invariant

mass around the threshold between continuum and the bound state. This is very much like a similar cancellation in the proton-neutron continuum with the deuteron in the

channel. Based on comparative fits with a common Tsallis distribution of the experimental cross-sections for prompt production of deuterons and

in pp collisions with a finite

, we find a strong argument for questioning the bound state nature of this state, which also suggests that the large observed production rate could be consistent with a half-bound state.
Microscopic study of electromagnetic properties and band spectra of neutron deficient 133,135,137Sm

Published: November 2019

Abstract
A microscopic high spin study of neutron deficient and normally deformed 133,135,137Sm has been carried out in projected shell model framework. The theoretical results have been obtained for the spins, parities and energy values of yrast and excited bands. Besides this, the band spectra, band head energies, moment of inertia and electromagnetic transition strengths are also predicted in these isotopes. The calculations successfully give a deeper understanding of the mechanism of the formation of yrast and excited bands from the single and multi-quasi particle configurations. The results on moment of inertia predict an alignment of a pair of protons in the proton (1h
11/2)2 orbitals in the yrast ground state bands of 133-137Sm due to the crossing of one quasiparticle bands by multi-quasiparticle bands at higher spins. The discussion in the present work is based on the deformed single particle scheme. Any future experimental confirmation or refutation of our predictions will be a valuable information which can help to understand the deformed single particle structure in these odd mass neutron deficient 133-137Sm.

Abstract
The electric quadrupole moment

and the magnetic moment

(or the

factor) of low-lying states in even-even nuclei 72-80Ge and odd-mass nuclei 75-79Ge are studied in the framework of the nucleon pair approximation (NPA) of the shell model, assuming the monopole and quadrupole pairing plus quadrupole-quadrupole interaction. Our calculations reproduce well the experimental values of

and

for 72,74,76Ge, as well as the yrast energy levels of these isotopes. The structure of the

states and the contributions of the proton and neutron components in

and

are discussed in the

-pair truncated shell-model subspace. The overall trend of

and

as a function of the mass number

, as well as their signs, are found to originate essentially from the proton contribution. The negative value of

in 72,74Ge is suggested to be due to the enhanced quadrupole-quadrupole correlation and configuration mixing.
Weak cosmic censorship conjecture and thermodynamics in quintessence AdS black hole under charged particle absorption *
Authors: He Ke-Jian , Hu Xin-Yun , Zeng Xiao-Xiong 
Published: November 2019

Abstract
Considering the cosmological constant as the pressure, this study addresses the laws of thermodynamics and weak cosmic censorship conjecture in the Reissner-Nordström-AdS black hole surrounded by quintessence dark energy under charged particle absorption. The first law of thermodynamics is found to be valid as a particle is absorbed by the black hole. The second law, however, is violated for the extremal and near-extremal black holes, because the entropy of these black hole decrease. Moreover, we find that the extremal black hole does not change its configuration in the extended phase space, implying that the weak cosmic censorship conjecture is valid. Remarkably, the near-extremal black hole can be overcharged beyond the extremal condition under charged particle absorption. Hence, the cosmic censorship conjecture could be violated for the near-extremal black hole in the extended phase space. For comparison, we also discuss the first law, second law, and the weak cosmic censorship conjecture in normal phase space, and find that all of them are valid in this case.

Published: November 2019

Abstract
Hyperglycemia is a condition in which the blood glucose level exceeds reasonable limits. Hyperglycemia is a clinical manifestation of diabetes disorder, a metabolic disorder characterized by resistance to insulin action, inadequate insulin secretion or both. Research has been conducted to determine the blood sugar level of male mice after given the biscuit from Kepok banana skin (Musa paradisiaca L.). The experiment was conducted experimentally with completely randomized design (CRD) design with five treatments, i.e., positive and negative control, the concentration of banana skin flour, i.e., 25%, 50%, and 75%. Each treatment was repeated as many as six tests. Before treatment, the mice were induced with alloxan to create hyperglycemia conditions. The biscuit from banana skins was given for 14 days. The results of research that has been done show that the administration of biscuit from Kepok banana skin could reduce blood sugar levels of mice who have hyperglycemia. Also, after given the biscuit from Kepok banana skin does not affect body weight of hyperglycemic mice. The biscuit from Kepok banana skin on levels 75% can be consumed for people with hyperglycemia to lower blood sugar.

Published: November 2019

Abstract

Physalis angulata has identified by molecular phylogenetic analysis and the results showed genetically close related with an anticancer plant, Withania somnifera. The aims of this preliminary study was to evaluate cytotoxicity effects of leaf extract of P. angulata (LEP) either in powder or pasta form on cells viability, cells proliferation, and inhibition on human ovary cancer cell lines (SKOV3) and human blood cancer cell lines (HL60). Cytotoxicity effects was analysed by MTS Cell Proliferation Assay Kit. Doxorubicin was used as positive control in this experiment. Surprisingly, two treatments (powder and pasta) have different toxic effects. We found that IC50 and viability (LC50) for SKOV3 cell lines for powder was between 93 ug/ml and 187 ug/ml, and 187 ug/ml and 375 ug/ml for pasta. IC50 for HL60 cell lines was 23 ug/ml for powder and around 18 ug/ml for pasta. Cell viability (LC50) of HL60 treated with LEP showed that 23 ug/ml for powder or 46 ug/ml for pasta. These results suggested that LEP have antiproliferative and inhibition activities both on SKOV3 or HL60.

Abstract
Evaluation of the creditor’s ability needs to be done before the debtor provides the loan. The purpose of system design in this study is to establish a creditworthiness system by implementing K-Mean based Z-Score. The method of system design that used in this research is Rational Unified Process (RUP). The case study of those research is in the Savings and Loans Cooperative (KSP) at Junior High School 1st Cileunyi, Bandung. K-Means method-based Z-Score is used by the author as a model for solving problems, wherein the author uses three clusters with four parameters that applied to the method. Based on the results of the experiments, the application can classify prospective credits into three groups based on the four parameters. Those three groups among others: “OK” as many as 37 members, “Warning” as many as 28 members and “Bad” as many as 5 members. The results of those groups are used as a credit recommendation to the KSP.

Published: November 2019

Abstract
The anaysis of the association between the variables of a three-way table requires a very different approach to the conventional correspondence analysis techniques. The conventional technique involves by collapsing three-way table into two-way table form. By doing so, no information about three-way interaction among variables. To included interaction among three variables at once, we consider higher-order singular value decomposition (HOSVD) Tucker3. Through the HOSVD Tucker3 decomposition, we can derive marginal of row, column, annd tube categories. Using those marginals, we can easily visualize dependence of the three categories. As a case study, Tucker3 is applied to household data which containing information on race, educational attainment and employment status.

Abstract
The partition dimension of the graphs is one of the open problems in graph theory. One of the methods which are used researcher is a graph operation, for example, subdivision operations. Let G be a connected graph of order n. The subdivision operation of G is an operation in G that replaces any edge by a path P

i
= 1, then the subdivision graph is denoted by S(G). One of the most recent results on the partition dimension of subdivision operation in the general graphs is published by Amrullah, et al 2016. However, the results show only an upper and lower bounds of the subdivision graph partition dimension. Therefore, this paper is devoted to finding the partition dimension of subdivision graph S(G) and S(G(E; k

(uv) and. A total k-labeling of G is called edge irregular if every two distinct edges have distinct weight. The total edge irregularity strength of G is denoted by tes(G) and defined by the minimum k such that G has an edge irregular total k-labeling. The labeling was introduced by Bača et al. in 2007. In this paper, we determine the total edge irregularity strength of some copies of ladder graphs.
Fuzzy epidemic model in a population having critical density dependent growth

Published: November 2019

Abstract
The epidemic growth model is an important tools used in predicting the future of a population and the spread of disease in the population. An epidemic model is usually formed in a differential equation or a system consisting several differential equations. The biological complexity in the underlying population affects the complexity of the epidemic model. One example of biological complexity is the Allee effect which reflects the critical density dependent of the population growth. In this paper we discuss a Logistic epidemic by considering this Allee effect on the population. Dynamic analysis is performed by determining fixed point and its stability analysis in crisp condition. We found the Basic Reproduction Ratio (BRR) for the model. The properties of the solution of the model are explored by the use of its numerical solution. Since we also consider the fuzziness of parameters and variables in the model, the numerical solution is generated using a modified Runge-Kutta method. This is done to explore the effect of inaccuracy and uncertainty which often occur in epidemiological problems.
