Published: June 2020

Abstract
Improvement in quality health care has now become a must that both developed and developing countries work on improving their health care system, especially in midwifery emergencies, using information systems. UNICEF has developed a midwifery referral system with its program known as Expanding Maternal and Newborn Survival to speed up the referring process. AHP is one of the information system procedures that support decision making to speed up the determination of health care facilities. This research discusses some journal articles by conducting a detailed analysis of their preliminary studies, research objectives, achievement indicators, variables, and methods used. It is expected that readers can briefly learn some benefits of AHP in health care. This research employed the PRISMA protocol guidelines. Chosen journal articles are full papers published in reputable journals. Inclusion and exclusion criteria were also implemented in choosing proper journal articles for this systematic literature review. It is found that the implementation of AHP in any type of health care service has proven to be very effective. It is expected that this literature review can serve as a reference for the implementation of AHP in health care based on practice evidence.

Abstract
Malaria has been a health problem in Indonesia, including in sub-district Kaligesing, district Purworejo of Central Java Province. Malaria has also been identified as an endemic especially in the villages of Jatirejo, Kaliharjo, and Somongari. The purpose of this study was to describe the epidemiology of malaria incidence based on distribution of cases, surrounding house related cases, and the Anopheles breeding place of malaria vectors. This descriptive based research with a case study approach investigated 61 malaria cases as respondents from 2016-2018 in Jatirejo, Kaliharjo and Somongari Villages sampled using total population method. The chosen variables were behaviour and environment of the respondents in relation to the presence of Anopheles vector breeding grounds. Data were analyzed descriptively and displayed in tables and maps. The results of the analysis showed that the average age of the malaria sufferer was 34 years old, male (60.7%), and most of them (45%) were coconut farmers. The most common symptoms of malaria experienced by respondents were fever, chills, headaches, and night sweats. In addition, 24.6% did not use insecticide-treated netting while sleeping. Spatially, the highest distribution of malaria cases was identified in Jatirejo Village, as its topography is plateau with a plantation area. Meanwhile, the existence of breeding places was found surrounding respondents’ houses. To prevent from having malaria, people have been advised to take precautions by wearing long clothes when going out at night, using repellents/anti-mosquito treatments, providing larvicides at breeding sites around their house.

Abstract
Diabetic ulcers are open sores on the skin through into the dermis, which if not properly managed, can increase amputation cases. Over the past few decades, ozone generated using plasma medical technology has been investigated to have the ability as an agent that helps wound healing. This study aims to evaluate the effect of topical ozonated VCO on the diabetic wound healing in the diabetic mice model. This study was an experimental study with post-test control design. Ulcer wound model was made in 50 diabetic male Wistar mice. They are divided into 5 groups, the first group (control) was given conventional therapy and the other groups (treatment) were given conventional therapy and topical ozonated VCO with different flow durations (0 min, 90 min, 7 h, 14 h). Then, the characteristics of wound healing (macroscopic and wound lengths) were observed in day 1, 3, 5, 7, and 14. The results of this study showed that the reduction of wound length was proportionally related to the duration of ozone flow. Topical VCO with the longer duration of ozone flow would heal the wound more quickly and had the shortest wound length at the end of the observation. VCO with ozone flow for 14 hours (16837.10 µm) had the biggest reduction of wound length, following by VCO with ozone flow for 7 hours (14209.64 µm), 90 minutes (14071.96 µm), 0 minutes (8531.99 µm), and control group (6370.77 µm). Therefore, we concluded that topical ozonated VCO improved diabetic wound healing process in diabetic ulcer mice model and can be used as adjuvant therapy for diabetic ulcers.

AbstractThe spread of HIV infection one of which is affected by cell to cell transmission. A dynamical model of HIV-1 infection in CD4+T cells with considering viral transmission from cell to cell and antibody response is constructed in this paper. Antibody response determines viral load in early HIV-1 infection. The existence and stability of the equilibrium is investigated by the basic reproduction ratio. The local stability of uninfected equilibrium is analyzed using Routh Hurwitz linearization. After investigating the local stability, we construct a Lyapunov function to investigate the global stability of endemic equilibrium. Numerical simulation is given to illustrate the control of HIV-1 infection based on the effect of antibody response and the effectiveness of antiretroviral treatment.

Abstract
Liver cancer is one of the highest causes of death in the world. According to IARC data in 2018, the number of cases of liver cancer reached 841,080 cases and 781,631 of them declared dead. One effort that can be done to reduce cases of death from liver cancer is early detection by doing a classification on MicroRNA data. MicroRNA can be used to identify whether a cell is a cancer cell or not at the earliest stages. MicroRNA data studied was obtained from the GDC Data Portal of the National Cancer Institute (NCI). The Deep Neural Network (DNN) method is one of the methods that can be used in classifying cancer. Data normalization in the DNN method brings input values with an unlimited range into a limited range of output values. Data normalization at data pre-processing work more optimally by adding activation functions and Batch Normalization in each hidden layer. Different types of normalization and use of different activation functions can be compared to get the best accuracy value for DNN. This study compares three types of data normalization, namely Min-Max, Sigmoid, and Softmax. Whereas the activation functions being compared are ReLU, Sigmoid, and TanH. The results showed the best accuracy for the classification of liver cancer with MicroRNA data obtained using Min-Max data normalization, ReLU activation function, batch normalization with parameters of 2 hidden layers, 200 epochs, and 0.004 learning rate with an accuracy value reaching 98.33%.

Abstract
Mathematical modeling can describe about how the epidemic model like virus HIV/AIDS interaction with human, from susceptible individual become individual AIDS. Furthermore, the model is built in the acceleration fraction how fast susceptible individuals can be asymptomatic HIV infected individuals. It can be solved to get the point of free disease and its stability, and also to get endemic point and its stability. The stability for the free disease will get from the Routh’s criterion stability, and for the endemic will be analyzed by Lyapunov function. In the paper, the point of free disease will be asymptotically stable if the basic reproduction of the model less than one, and the point of endemic will stable with Lyapunov if the basic reproduction more than one.

Plasmonic semiconductor nanoparticles showing nonlocal response

Published: June 2020

Abstract
We predict that localized surface plasmons (LSP) in semiconductor particles exhibit spatial nonlocal response effects as the geometry enters the nanometer scale. To investigate these nonlocal effects, we first apply the hydrodynamic model (HDM) to nanospheres of two different semiconductor materials: intrinsic InSb and n-doped GaAs. Our results show that the semiconductors indeed display nonlocal effects, and that these effects are even more pronounced than in metals, and more tunable as well. We also present a two-fluid hydrodynamic model for semiconductors containing electrons and holes (from thermal or external excitation) or light and heavy holes (in p-doped materials). The two-fluid model predicts the existence of two longitudinal modes, an acoustic and an optical, whereas only an optical mode is present in the HDM. By extending nonlocal Mie theory to two plasmas, we simulate the optical properties of two-fluid nanospheres and predict that the acoustic mode gives rise to peaks in the extinction spectra that are absent in the HDM. And from a numerical study, we predict that by considering dimers rather than monomers of nanowires, the extinction cross section and field enhancement of the acoustic localized surface plasmon resonances can increase substantially. In this conference proceedings, we present calculations of the two-fluid GNOR model, which show that acoustic surface plasmon modes are surprisingly robust against size-dependent broadening.

Abstract
The work is devoted to the study of the gyroscopic phenomena of a rotating C60 fullerene molecule on interaction with a moving particle. To determine the precession characteristics of the C60 fullerene molecule, the pairwise interaction model of nonpolar Lennard-Jones molecules was used. The rotational motion of fullerene was described by the dynamic Euler equations. The influence of the angular velocity and direction of rotation of the fullerene molecule on the deviation from the initial position is investigated.
A study of the chirality-related properties of octagonal and dodecagonal carbon nanotubes
Authors: Krishna Maalini 
Published: June 2020

Abstract
The use of carbon nanotubes has grown rapidly over the past decades. The potential of these nanotubes is high and extremely useful in daily life, especially in computer systems and circuits, due to the flexibility of the properties of the nanotubes that can be controlled during their production process. Computer systems rely on the fast conductivity to function. Materials such as graphene, used in carbon nanotubes have proved to be highly conductive materials, more so than the silicon wires used today. This paper explores the possibilities of a new type of carbon nanotube, which has an octagonal lattice instead of a hexagonal lattice of a traditional carbon nanotube, and finds expressions for its basic properties. These properties are compared with that of a traditional hexagonal lattice. This could provide useful applications in the future of physics and computer systems. With the growing need for higher computational power or the design of new materials, a study in such octagonal-shaped carbon nanotubes could prove useful. Dodecagonal-shaped carbon nanotubes are also proposed in this paper with chiral properties equivalent to that of hexagonal carbon nanotubes, which could be explored further as well.

Abstract
The effect of hydrogen plasma treatment on the electrical and optical properties of GaN NWs/Si based vertical hetero structures synthesized by the method of plasma molecular beam epitaxy is studied. The effect of treatment has been carefully studied by variation of the passivation duration. Measurements of the electron beam-induced current (EBIC) technique showed the absence of potential barriers between the active parts of the diode and the contacts, which indicates the ohmic behavior of the latter. The current - voltage characteristics show that hydrogen can efficiently passivate recombination centers at the GaN NWs/Si heterointerface. It is established that the optimal passivation duration, providing improved electrical properties, is 10 minutes in the adopted passivation modes. It is shown that a longer treatment causes a deterioration in electrical properties.

Published: June 2020

Abstract
The development of adaptive nanomaterials that are responsive to changes in their surrounding environment would enable such materials to be used in wide range of applications such as drug delivery vehicles or biosensors. Reversible boronic ester chemistry, which is used in this work, has several advantages as a building block for making adaptive nanomaterials including the ease of preparation, high sensitivity to external stimuli such as pH, and relative stability especially when compared to other non-covalent reversible systems. Herein, by using small boronic acids as anchor and peptides as connectors, we report progress in the initial development of novel, peptidyl-based pH dependent adaptive nanomaterials using reversible boronic ester chemistry and its characterisation using small angle X-ray scattering.

Published: June 2020

Abstract
When using the frequency-modulated continuous-wave (FMCW) approach for layer thickness determination of dielectrics, such as multilayer pipe walls, the resolution is usually limited by the bandwidth. For thinner layers, we compare the measurement signal with potential model signal outputs. Since our approach results in high computation efforts by using brute force optimization, spectral estimation may present an alternative for high resolution distance and hence thickness determination. In this contribution, we compare results of a parametric algorithm (modified covariance method) and a subspace method (multiple signal classification, MUSIC) with the results of our approach.

Abstract
Creation of the biological tissue phantoms especially breast tissue cancer in the terahertz frequency range is an actual problem of medical physics. This paper suggests using soy protein as one of the main component of breast tissue phantom instead of gelatin, as it’s water-and fat-holding substance, “quasi-bioidentical” to animal proteins and their chemical characteristics are stable in time. Implemented phantoms were analyzed experimentally by using terahertz pulsed spectroscopy, obtained results were compared with spectra of adipose, fibrous and cancer tissue (human female breast tissue).

Published: June 2020

Abstract
The excessive ethylene gas and water vapor are not desired particularly in the fruit post-harvest handling, since the substances can shorten the shelf life and accelerate the rooting of the fruits thus its presence in the fruit handing is needed to be control. In this research, a multi absorber has been manufactured from calcium chloride (CaCl2) and potassium permanganate (KMnO4) with active rice husk as a matrix. The purpose of this study is to observe the capability of multi absorber of CaCl2 and KMnO4 trapped into rice hush matrix in absorbing water vapor and ethylene. In this study, CaCl2 and KMnO4 solutions with mol ratio of 1 : 2; 2 : 1; 1 : 3 and control (with CaCl2(1 mol) or KMnO4(1 mol)) were impregnated into the matrix. The experiment resulted that the ratio of CaCl2 (1 mol): KMnO4 (3mol) was able to absorb KMnO4 as much as 0.89 mg ethylene per 3 g absorber for 1 h of exposure. It also worked for absorbing water vapor as much as 1.03 g/g absorber for 7 days of storage at RH97%. Based on this experiment, the multi absorber resulted from this research is potential to be applied as ethylene and water vapor absorber.
