Minimizing Number of Tardy Jobs in Flow Shop Scheduling Using A Hybrid Whale Optimization Algorithm
Authors: Utama D M 
Published: March 2021

Abstract
The number of Tardy Jobs is a critical performance in scheduling because it can increase customer trust in the company. If the number of tardy jobs is large, trust in the company decreases. This article aims to minimize the number of tardy jobs in Permutation Flow Shop Scheduling Problems (PFSSP) using Hybrid Whale Optimization Algorithm (HWOA). We propose the HWOA method for minimizing the number of tardy jobs in PFSSP. There are 5 phases of the proposed HWOA algorithm. Phase 1 is replacing 1 of the initial search agent population replaced by the NEH-EDD heuristic procedure. The Random Search Agent position’s initialization and the Large Rank Value (LRV) is the second phase. Phase 3 is the whale exploration phase. Phase 4 is the whale exploitation phase. The last phase (5) is the local search exchange procedure. Numerical experiments were conducted to test the performance of HWOA, and it was compared with the previous research algorithm. Algorithm experiment results show that the HWOA algorithm has better performance than Particle Swarm Optimization and Genetic Algorithms.

Abstract
Call center staff is a staff who work in providing repair or servicing services by telephone. This staff is in charge of explaining the solutions to be carried out by the company in obtaining answers. Call center staff must have a good temperament and smart. In getting good staff, companies can use a decision support system with the VIKOR method to select and select these staff. Five criteria will be tested in determining the staff. The results of the VIKOR method can help companies find call center staff that match company expectations. The ranking results can determine the level of results of the VIKOR method test on call center staff who are used as candidates or alternatives. By implementing this method, the search for call center staff will be better.

Abstract
The main energy source is still predominantly using energy sources derived from oil, coal and natural gas. As it is known that this type of energy source is limited in number because it is a non-renewable energy source. The main result of this limited quantity is the increase in the price of petroleum in the market. The price of fuel in Indonesia, which continues to rise in line with world oil prices, is one of the causes of electricity tariffs in Indonesia to become increasingly expensive. Several studies have been conducted to overcome these problems, one of which is finding alternative energy sources as a substitute for non-renewable energy sources. One of the efforts made is by utilizing solar energy using solar cells. These solar cells can convert sunlight directly into electrical energy using the principle of “Photovoltaic Effect” without causing air pollution or water pollution. It cannot be denied that solar energy is one of the environmentally friendly energy sources and is very promising in the future, because no pollution is generated during the energy conversion process, and this energy source is widely available in nature. This paper is going to calculate the characteristics solar power plants using solar panels 150WP and calculate the maximum power generated by a solar power plant resulting from. So that it can be analyzed the performance of the system design the solar power plant for a power capacity of 150WP.

Published: March 2021

Abstract
Varying methods were tested on the improvement of heat transfer in order to upgrade the concerning equipment, mostly in thermal performance devices. These methods revealed important impacts when employed in heat exchanger pipes. One of the significant methods utilized was the passive performance technique. Corrugations characterize the passive method. Moreover, it offers efficient enhancement of heat transfer due to its joint turbulators and extended surface features. So, Computational Fluid Dynamics (CFD) method is applied for water flowing with a range of Reynolds number (Re) from 1500 to 23000 in different corrugated pipes configurations. This research target to investigate the flow pattern, pressure drop, and thermal performance for smooth and corrugated pipes. The criteria of thermal performance evaluation are analysed for corrugated pipes, and the computational outcomes of pressure drop, heat transfer coefficient (h), friction factor Nusselt number (Nu), ratios of (f/fo) and (Nu/Nuo) are investigated with those of smooth plain. Outcomes revealed the best range of thermal performance is between 1.3 to 1.1 for the pipe, which has the corrugated ring diameter 0.5 mm for Re of 1500.

Abstract
The effect of digital transmission impairments is seen from a diagram called an eye pattern. Measurements of the device can be represented in a simulation. Our motivation in conducting this simulation aims to dig deeper into the variation of parameter changes that exist in improving the eye pattern opening angle. The raised cosine pulse with roll-off (a) of 0.3 was used as the basis for this study, using the Matlab simulation. Important parameter values have been explored to show the best data. Finally, we suggest that we continue to explore optimization techniques for the best results for this eye pattern visualization.

Published: March 2021

Abstract
Domestic waste standard parameters according to PermenLH No. 68 Years. 2016 determined one of them based on the pH, COD and Ammonia values. Most household wastewater has these values, so a purification process is required before the wastewater returns to groundwater. One of the treatments carried out is in the form of ozone technology which can decompose organic and inorganic pollutants and kill microorganisms in the waste. The purpose of this study was to determine the quality of household wastewater resulting from ozone bubble treatment combined with zeolite filters. To support the research, we used the pH, COD and Ammonia measurement methods from the treated samples. The method used is in the form of ozone treatment and zeolite filters in wastewater with a variable length of treatment time. From the research results, it can be seen that the combination of ozone and zeolite filter has an effect on decreasing the concentration of COD and ammonia in wastewater.

Abstract
The need for telecommunication in this era is very important and increasing. Including communication that uses digital data such as VoIP (Voice over Internet Protocol). One of the SIP servers (Session Initials Protocol) that worked well is the Kamailio server. It’s operating on an open-source and operating on the Linux system. The SIP communication system at the airport designed on this research uses Kamailio as SIP server. The goal is to make communication easier at the airport by using existing network facilities such as wi-fi. The quality of service parameters (QoS) of this study is a delay, throughput, and packet loss on the transmission of text messages, voices, and videos. Results obtained indicate the good value of that communication standard. 114 with 86.62 ms delay parameters for text, 110.10 ms for votes, and 127.52 ms for the video. The throughput shows the average varies with 330 kbps, 45.71 kbps, and 72.3 kbps according to the type of communication. The zero-percent value of packet loss shows all communication on this system is sent to the user in real-time. In this study, it can be concluded that the Kamailio server can be used as a SIP-based communication system at the airport. Testing shows good results on QoS text messages, voice calls, and video calls.
Loeb extension and Loeb equivalence

Published: March 2021

In [J. London Math. Soc. 69 (2004), pp. 258–272] Keisler and Sun leave open several questions regarding Loeb equivalence between internal probability spaces; specifically, whether under certain conditions, the Loeb measure construction applied to two such spaces gives rise to the same measure. We present answers to two of these questions, by giving two examples of probability spaces. Moreover, we reduce their third question to the following: Is the internal algebra generated by the union of two Loeb equivalent internal algebras a subset of their common Loeb extension? We also present a sufficient condition for a positive answer to this question.
Refugees And Patronage: A Political History Of Uganda’s ‘Progressive’ Refugee Policies
Authors: Betts Alexander 
Published: March 2021

Abstract
Uganda’s self-reliance policy for refugees has been recognized as among the most progressive refugee policies in the world. In contrast to many refugee-hosting countries, it allows refugees the right to work and freedom of movement. It has been widely praised as a model for other countries to emulate. However, there has been little research on the politics that underlie Uganda’s approach. Why has Uganda maintained these policies despite hosting more refugees than any country in Africa? Based on archival research and elite interviews, this article provides a political history of Uganda’s self-reliance policies from independence to the present. It unveils significant continuity in both the policies and the underlying politics. Refugee policy has been used by Ugandan leaders to strengthen patronage and assert political authority within strategically important refugee-hosting hinterlands. International donors have abetted domestic illiberalism in order to sustain a liberal internationalist success story. The politics of patronage and refugee policy have worked hand-in-hand. Patronage has, in the Ugandan case, been integral to the functioning of the international refugee system. Rather than being an inevitably ‘African’ phenomenon or the unavoidable legacy of colonialism, patronage politics has been enabled by, and essential to, liberal internationalism.
Invited Commentary: Reckoning With Our Biases in Epidemiology
Authors: Galea Sandro 
Published: March 2021

Abstract
Biases and in-group preferences limit opportunities for persons of all identities to flourish in science. Decisions made by those in charge of leading professional meetings about which presentations to feature prominently and by academic journal staff about which articles to publish reinforce these biases. The paper by Nobles et al. (Am J Epidemiol. 2021;190(9):1710–1720) showed that women are less likely to be selected to be symposium presenters in the field’s pre-eminent scientific meeting than men. The scientific and moral arguments for promoting diversity of engagement by persons of all identities in the field are abundantly clear, calling for efforts to mitigate the effect of these in-group biases. I offer 3 suggestions for how we can achieve better diversity in our field: 1) increase our discussions of the importance of diversity and raise consciousness about the issue consistently; 2) ensure that only blinded, peer-reviewed presentations are advanced at professional meeting; and 3) publish only blinded, peer-reviewed papers in leading journals in the field. These steps—together with broader system-wide efforts to maximize diversity among trainees and faculty—can pave the way for any field to become welcoming to all, irrespective of any axes of identity.
HiG2Vec: hierarchical representations of Gene Ontology and genes in the Poincaré ball
Authors: Kim Jaesik , Kim Dokyoon , Sohn Kyung-Ah 
Published: March 2021

AbstractMotivationKnowledge manipulation of Gene Ontology (GO) and Gene Ontology Annotation (GOA) can be done primarily by using vector representation of GO terms and genes. Previous studies have represented GO terms and genes or gene products in Euclidean space to measure their semantic similarity using an embedding method such as the Word2Vec-based method to represent entities as numeric vectors. However, this method has the limitation that embedding large graph-structured data in the Euclidean space cannot prevent a loss of information of latent hierarchies, thus precluding the semantics of GO and GOA from being captured optimally. On the other hand, hyperbolic spaces such as the Poincaré balls are more suitable for modeling hierarchies, as they have a geometric property in which the distance increases exponentially as it nears the boundary because of negative curvature.ResultsIn this article, we propose hierarchical representations of GO and genes (HiG2Vec) by applying Poincaré embedding specialized in the representation of hierarchy through a two-step procedure: GO embedding and gene embedding. Through experiments, we show that our model represents the hierarchical structure better than other approaches and predicts the interaction of genes or gene products similar to or better than previous studies. The results indicate that HiG2Vec is superior to other methods in capturing the GO and gene semantics and in data utilization as well. It can be robustly applied to manipulate various biological knowledge.Availabilityand implementationhttps://github.com/JaesikKim/HiG2Vec.Supplementary informationSupplementary data are available at Bioinformatics online.
PecanPy: a fast, efficient and parallelized Python implementation of node2vec
Authors: Liu Renming , Krishnan Arjun 
Published: March 2021

Abstract

Summary
Learning low-dimensional representations (embeddings) of nodes in large graphs is key to applying machine learning on massive biological networks. Node2vec is the most widely used method for node embedding. However, its original Python and C++ implementations scale poorly with network density, failing for dense biological networks with hundreds of millions of edges. We have developed PecanPy, a new Python implementation of node2vec that uses cache-optimized compact graph data structures and precomputing/parallelization to result in fast, high-quality node embeddings for biological networks of all sizes and densities.

AbstractInformation and Communication Technologies (ICTs) permeated social work practice before coronavirus disease 2019 (COVID-19). In addition to ICT-based formal services (e.g. e-counselling), social workers used ICTs informally as an adjunct to face-to-face practice. Building on our previous research, our cross-sectional online survey examined social workers’ informal use of ICTs in four countries: Canada, the USA, Israel and the UK. The survey was administered through Qualtrics software among social workers across Canada (n = 2,609), the USA (n = 1,225), Israel (n = 386) and the UK (n = 134), and analysed using IBM SPSS Statistics version 26. The findings substantiate the ubiquitous use of informal ICTs in social work practice, as an adjunct to face-to-face treatment, across the four countries. Given the current, unprecedented context of COVID-19, we discuss the meaning of our findings related to access, ethical considerations (e.g. professional boundaries) and supervision in the context of restricted face-to-face practice. We discuss the implications for social work practice, education and research, and conclude that in the COVID-19 context, there is an even greater need for research, clinical discussion, supervision and policy on informal ICT use in social work practice.
An Indomalesian origin in the Miocene for the diphyletic New World jewel orchids (Goodyerinae, Orchidoideae): molecular dating and biogeographic analyses document non-monophyly of the Neotropical genera

Published: March 2021

AbstractThe jewel orchids (Goodyerinae), named after their often colourful leaves, have a pantropical distribution with a clear Asian centre of diversity. However, the Nearctic and Neotropical America together form a second centre of diversity, with one-third of known species of Goodyerinae. Previously, only a few American samples have been included in phylogenetic studies, and their putatively Asian origins and American divergence times were poorly known. To elucidate these topics, we inferred phylogenetic trees, performed molecular dating and reconstructed biogeographic history using nuclear ribosomal ITS and plastid matK sequences for 34 species of Goodyerinae from the New World and 76 previously published accessions of Cranichideae. Our well-supported phylogenetic topology suggests two independent dispersal events to the New World from the Indomalesian region during the Miocene. The first inferred dispersal of a Neotropical clade diverged c. 11 Mya from their most recent common ancestor (MRCA), comprising three highly supported subclades that do not match the limits of Aspidogyne, Kreodanthus and Microchilus as previously circumscribed. The second dispersal involved a largely Nearctic clade of Goodyera s.l. diverging c. 8.4 Mya from the MRCA and exhibiting a complex biogeographic history with subsequent dispersals between the Nearctic and Indomalesia. The occurrence of these species in gallery forests putatively prevented vicariance events imposed by the expansion of the Chacoan region as previously detected for epiphytic Orchidaceae. Eighty-nine nomenclatural combinations and three new names in Microchilus are proposed.

Abstract
We examined the effect of microRNA-320b (miR-320b) on tumor growth and angiogenesis in lung cancer and also determined its downstream molecular mechanisms. Lung cancer tissues and adjacent non-cancerous tissues were collected from 66 patients with lung cancer. miR-320b expression was experimentally determined to be expressed at low level in cancer tissues. The results of gain-of-function experiments suggested that miR-320b overexpression suppressed cancer cell invasion, tube formation, tumor volume and angiogenesis in xenografted nude mice. Hepatocyte nuclear factor 4 gamma (HNF4G) was identified as a target of miR-320b based on in silico analysis. Dual-luciferase reporter gene assays further identified the binding relationship between HNF4G and miR-320b. Lung cancer tissues exhibited increased expression of HNF4G and insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2). Meanwhile, HNF4G knockdown suppressed IGF2BP2 expression, thereby repressing cancer cell invasion and tube formation. Furthermore, IGF2BP2 modified m6A to increase the expression of thymidine kinase 1 (TK1), thus promoting angiogenesis. In nude mice, restoration of TK1 reversed the suppressive effect of miR-320b overexpression on tumor growth rate and CD31 expression. In conclusion, miR-320b suppresses lung cancer growth and angiogenesis by inhibiting HNF4G, IGF2BP2 and TK1.
