Predicting Ion Mobility Collision Cross Sections using Projection Approximation with ROSIE-PARCS Webserver
Authors: Turzo SM Bargeen , Seffernick Justin , Lyskov Sergey , Lindert Steffen
Published: February 2023

Ion mobility (IM) coupled to mass spectrometry informs on the shape and size of protein structures in the form of a collision cross section (CCSIM). While there are several computational methods for predicting CCSIM based on protein structures, including our previously developed PARCS, the process usually requires prior experience with the command-line interface (CLI). To overcome this challenge, here we present a web application on the ROSIE webserver to predict CCSIM from protein structure using projection approximation with PARCS. In this web interface, the user is only required to provide one or more PDB files as input. Results from our case studies suggest that CCSIM predictions (with ROSIE-PARCS) are highly accurate with an average error of 6.12%. Furthermore, the absolute difference between CCSIM and CCSPARCS can help in distinguishing accurate from inaccurate AlphaFold2 protein structure predictions. ROSIE-PARCS is designed with a user-friendly interface, is available publicly, and is free to use. The ROSIE-PARCS web interface is supported by all major web browsers and can be accessed via this link (https://rosie.graylab.jhu.edu).

Published: February 2023

Photoionisation schemes for mass spectrometry, either by laser or discharge lamps, have been widely examined and deployed. In this work, the ionisation characteristics of a Xenon discharge lamp (Xe-APPI, 9.6/8.4 eV) have been studied and compared to established ionisation schemes, such as atmospheric pressure chemical ionisation, atmospheric pressure photoionisation with a Krypton discharge lamp (Kr-APPI, 10.6/10 eV) and atmospheric pressure laser ionisation (266 nm). Addressing the gas-phase ionisation behaviour has been realised by gas chromatography coupling to high-resolution mass spectrometry without the usage of a dopant. For the multicomponent standard, it has been found that Xe-APPI is able to ionise a broad range of polycyclic aromatic hydrocarbons as well as their heteroatom-containing and alkylated derivatives. However, thiol and ester compounds could not be detected. Moreover, Xe-APPI revealed a high tendency to generate oxygenated artefact, most likely due to a VUV absorption band of oxygen at 148 nm. Beneficially, almost no chemical background, commonly caused by APCI or Kr-APPI due to column blood, plasticisers or impurities, is observed. This advantage is noteworthy for evolved gas analysis without pre-separation or for chromatographic co-elution. For the complex mixtures, Xe-APPI revealed the predominant generation of radical cations via direct photoionisation with a high selectivity towards aromatic core structures with low alkylation. Interestingly, both Xe-APPI and Kr-APPI could sensitively detect sterane cycloalkanes, validated by gas chromatographic retention. The narrowly ionised chemical space could let Xe-APPI find niche applications, e.g., for strongly contaminated samples to reduce the background.

Data tersebut analisis secara kualitatif menggunakan metabahasa semantika lami, sebuah pendekatan untuk mengkaji berbagai bentuk, struktur, dan makna bahasa secara utuh dengan prinsip “satu bentuk untuk satu makna dan satu makna untuk satu bentuk”. Pendekatan ini menggunakan kata-kata yang tepat untuk menjelaskan sesuatu tanpa berbelit-belit atau berputar-putar. Hasil penelitian menunjukkan bahwa makna memasak dalam bahasa Muna dapat diekspresikan dengan berbagai leksikon dan masing-masing leksikon memiliki makna distintif, yakni verba makna memasak menggunakan air seperti pada verba ghaudan to:fi, makna memasak menggunakan minyak seperti pada verba hole: dan sanggarae, dan makna memasak tanpa menggunakan air dan minyak seperti pada verba tunu dan rawue. Sesuatu yang dimasak dan komponennya (air, api, asap, atau minyak) yang digunakan untuk memasak menentukan jenis verba yang akan digunakan. Verba-verba memasak tersebut dapat mengindikasikan atau menggambarkan obyek yang dimasak dan proses memasak. Walaupun demikian, agen atau pelaku sebagai subyek bersifat bebas dan tidak tergantung baik pada predikat maupun obyek, atau sebaliknya.This paper aims at investigating the meaning of cooking verbs in Muna language. The data were collected through interview with recording and noting techniques. It was analyzed qualitatively by using natural semantics metalanguage (NSM), an approach to investigate various forms, structure, and meaning in the whole with principle “one form for one meaning and one meaning for one form”. It uses appropriate words to explain something without using other lexicons or without obscurity. The result of this study shows that meaning of verbs cooking in Muna can be expressed by a number of lexicons and each form has distinctive meaning in expressing the meaning of cooking, namely to cook using water, such as ghau and to,fi: to cook using oil, such as hole and sanggarae, and to cook without using water and oil, such as tunu and rawue. Something that will be cooked and component used to cook determines the kinds of those verbs. Those verb of cooking in Muna language can indicate or describe the object which is cooked and process of cooking. However, actor or agent as subject is independent either predicate or object, and vice versa.

This research is an analytic painting about the content of educational values in the oral literature of the people of Wakatobi. All data in this study were sourced from in-depth interviews, observations, and document studies. Considering this research is related to aspects of oral literature in the socio-cultural space, the data analysis was carried out using a hermeneutic phenomenology approach. Folklore in the form of folklore (tula-tula) and kabanti (folksong) are two forms of oral literature that are still used as educational media by Wakatobi people. This study found that the contents of the tula-tula and kabanti that grew in the cultural space of the Wakatobi people functioned as treasures of knowledge and entertainment value and contained ethical values. Through oral literature, the Wakatobi people consciously try to build values in order to maintain harmony with nature, microcosmic relations between humans, and macrocosm relations to the Creator. The characteristics of the learning model in the tula and kabanti, are more information-giving, in the form of facts and memories, generally one-way, and the style of the speaker/teacher is preferred in conveying messages, intonation, improvisation, enthusiasm, and systematic message. Penelitian ini merupakan lukisan analitik tentang muatan nilai pendidikan dalam sastra lisan orang Wakatobi. Seluruh data dalam penelitian ini bersumber dari hasil wawancara mendalam, pengamatan, serta studi dokumen. Mengingat penelitian ini terkait dengan aspek sastra lisan dalam ruang sosial budaya, analisis data dilakukan dengan menggunakan pendekatan fenomenologi hermeneutik. Folklor dalam bentuk cerita rakyat (tula-tula) dan kabanti (folksong) adalah dua bentuk sastra lisan yang hingga kini masih digunakan sebagai media pendidikan oleh orang Wakatobi. Penelitian ini menemukan bahwa muatan tula-tula dan kabanti yang tumbuh dalam ruang budaya orang Wakatobi tidak hanya berfungsi sebagai khazanah pengetahuan dan bernilai hiburan, tetapi juga mengandung nilai-nilai etika. Melalui sastra lisan, orang Wakatobi secara sadar berusaha membangun nilai dalam rangka menjaga harmoni dengan alam, hubungan mikrokosmis sesama manusia, dan hubungan makrokosmos kepada sang Pencipta. Karakteristik model pembelajaran dalam tula-tula dan kabanti lebih bersifat pemberian informasi berupa fakta dan ingatan, umumnya bersifat satu arah, dan gaya penutur/guru lebih diutamakan dalam menyampaikan pesan, intonasi, improvisasi, semangat, dan sistematika pesan.

Published: February 2023

Autism Spectrum Disorder (hereinafter referred to as ASD ) is a developmental disorder experienced by a person since childhood, which causes an inability to communicate and express feelings. This research is an extension of previous research that investigated the language development of ASD children in relation to aspects of discourse that affect speech omission (Halliday & Matthiessen, 2013a). This study uses primary data derived from spontaneous speeches from 2 adults with ASD and 6 children with normal development. Children with normal development were included in the control group as a comparison to see the phenomenon of omission by using storytelling techniques with or without pictures. The second data collection technique is the storytelling technique without assistance. Researchers have prepared a general theme given to research participants. This study confirms and shows that the phenomenon of omission that is present in the speech of adults with ASD and children with normal development as a control group is not too much different quantitatively, but qualitatively has characteristics that can be used as comparisons. This special characteristic is related to the problem of autism spectrum disorders, namely the ability to communicate in responding to the interlocutor. In the end, the results of this study can contribute as a first step in diagnosing language disorders for people with ASD .

Alternative energy and the disposal of pollutants are important areas of development in the field of applied ecology. Microbial fuel cell technology uses pollutants as substrates with a negative energy cost. The electrochemical characteristics of microbial fuel cells (current strength, voltage, power density) were studied to assess the prospects for using Bacillus megaterium MK64-1 (the strain was deposited with VKPM under registration number B-7998) as a bioagent in them. Two nutrient media were used in the experiment – synthetic wastewater and Ashby medium. The volume of the anode chamber of the involved microbial fuel cells is 120 ml, the volume of the cathode chamber is 150 ml. The experiment was set up under aseptic conditions. The total microbial count of the working solution was 4×105 CFU/ml. The experiment included three biological and three analytical replicates. The duration of monitoring the dynamics of fuel cell performance was twelve days. Stabilization of the output voltage was recorded on the fourth day of the experiment. In Ashby medium, starting from the seventh day, electrical indicators continued to grow. The value of external resistance is revealed, at which the highest value of the MFC power is observed - 1 kΩ. The maximum value of the specific power of individual MFC was noted at the level of 14.1 mW/m² in Ashby medium and 13.2 mW/m² in synthetic wastewater. The difference in the composition of nutrient media did not have a significant effect on the dynamics of electrochemical parameters. It is concluded that the studied strain is promising for use in biological fuel cells.

The analysis of the results of physical performance of qualified freestyle wrestlers in the preparatory period of the annual training cycle is given. As performance indicators, the functional test of Rufier-Dixon was used, which reflects the degree of recovery of heart rate after a standard load, as well as the results of biochemical analyzes for the hormones testosterone and cortisol. Physical performance acts as a criterion for assessing the training and competitive activities of athletes. Evaluation of the results of dynamic load tolerance in terms of the ability of the cardiovascular system to adapt and recover showed that most of the examined wrestlers have an average working capacity, while the whole range of indicators is determined – from low to high working capacity. It is noted that changes in the functional state of the organism are somehow reflected in various reactions of the body's homeostasis, causing the inclusion of complex mechanisms of an adaptive nature. The values of the performance results of qualified freestyle wrestlers according to the data of biochemical examinations are presented. An assessment of the state of anabolic processes and the level of fitness through the values f the main male hormone testosterone showed the absence of an overstrain of adaptation systems. The level of testosterone in all examined athletes was determined within the normal range. The levels of cortisol, a hormone that reflects the influence of training stress, were determined as average for all freestyle wrestlers from the experimental group. In this study, the most informative was the assessment of the anabolism index, defined as the percentage ratio of serum testosterone concentration to cortisol concentration. A decrease in the anabolism index below the established norm is considered as a sign of overtraining. Among the examined qualified freestyle wrestlers in the preparatory period of the annual training cycle, athletes were identified in a state of overtraining in terms of the ratio of biochemical parameters - the hormones testosterone and cortisol. For most wrestlers, the state of overtraining is not defined. Comparison of the results of working capacity and data of biochemical studies of the examined wrestlers shows that the value of working capacity and the state of overtraining according to the anabolism index correlate, while the presence of the state of overtraining corresponds to low and below average values of physical performance indicators according to the Rufier-Dixon index. The inclusion of biomedical means of restoring physical performance for qualified freestyle wrestlers in the preparatory period of the annual cycle is proposed, the importance of the integrated use of functional and biochemical methods for monitoring the condition of training athletes is confirmed.
An Improved Finite Cloud Method With Uniformly Distributed Clouds and Enhanced Boundary Conditions
Authors: Oh Miew Leng , Hang See Pheng
Published: February 2023

Finite cloud method (FCM) employs the fixed kernel reproducing technique to construct the interpolation function and point collocation approach is adopted for the discretization. In this study, an improved FCM is proposed such that a node of interest is approximated with its nearest cloud. This feature enables a set of uniformly distributed clouds of various densities such that all the information in the problem domain is captured and stored in the clouds. Additionally, the instability of FCM near the boundaries is treated by having the boundary nodes also satisfy the governing differential equation. Besides, a splitting mechanism is suggested for the node refinement to improve the accuracy of solution. Parameters are introduced to control the density of clouds and the singularity of the moment matrices associated with the clouds. Thus, a more controllable numerical simulation is developed. Numerical examples are presented and the results have shown that the improved FCM produces a stable and better accuracy of solution.

Purpose: This study aims to identify the challenges, difficulties and opportunities for the SME sector in the Visegrad Group (V4) countries in the 21st century in the area of innovation and development, in particular digitalization. This research is justified by the prominent economic role of the SME sector and the key importance of adapting to the rapid pace of digitalization. Design/methodology/approach A literature review on this topic was used for the research, based on the Web of Science database. The scope of articles included in the survey was limited to peer-reviewed journal articles in English and published up to 2021. The process of selecting suitable studies for the search consisted of several steps, each of which aimed to include or exclude articles based on predefined criteria. Findings: The literature review has revealed significant gaps in the subject area. One of these is the lack of research on SMEs in the V4 countries. Another gap is the study of the relationship between SMEs and cloud computing from a computer science perspective, but other areas, not including the economic area, are less studied. Research limitations/implications: The limitations of the research include the database on which the study is based, the volume of the database and the criteria for the articles included in the study. Social implications: The study provides an overview for academics of who is working on the topic, from what aspect research has been done so far, and the links between publications. However, it may also be of interest to professionals interested in the subject area, if they want to see what areas are worth addressing, taking into account or just want to get a more comprehensive picture of the V4 SMEs in relation to digitalization. Originality/value: The importance of the study lies in the fact that it sheds light on the unanswered questions in the field and on the areas that have been little or not at all investigated by researchers. It can be used as a guideline for future studies in the field of cloud computing adoption by SMEs. Keywords: challenges, digitalization, SMEs, literature review.

Differentiation of climate and energy policy in the countries of the European Union
Authors:   University of Agriculture in Krakow, Luty Lidia , Zioło Monika ,   University of Agriculture in Krakow
Published: February 2023

Purpose: The energy policy of the European Union focuses mainly on three areas: renewable energy, reducing the emission of harmful pollutants, in particular CO2, and increasing the efficiency of electricity used. Sustainable energy management, in turn, is undoubtedly associated with the increased use of renewable energy sources ensuring energy security as well as the diversification of energy supplies that support and improve the quality of the environment. The aim of the article is to present the diversity of the European Union countries in terms of actions taken in the field of energy policy resulting from climate and energy goals. Design/methodology/approach: On the basis of the objectives of the energy policy presented in the EU directives, indicators describing the activities of the Member States in this respect were selected. Then, they were subjected to substantive and statistical verification, leaving 6 variables. The tool of Multidimensional Statistical Analysis, which is a synthetic measure, was used to develop a synthetic measure of the level of achievement of the goals of the climate and energy policy. Two types of analyses were used: static for international comparisons between the European Union countries, conducted for 2021, and dynamic, for the years 2011-2021. Findings: The most favourable situation in terms of activities aimed at reducing emissions of harmful substances and improving the energy efficiency of countries can be observed in the hitherto leaders of Sweden and Finland. Together with Denmark, these countries have set very ambitious national targets for achieving a share of at least 50% from renewable energy in gross final energy consumption. All countries have increased their energy productivity index. Bulgaria, Italy and Slovakia have made the greatest reductions in pollutant emissions. In the interests of energy independence, countries are trying to increase energy production from domestic resources. The greatest improvements in this field were made in Ireland, Latvia, Portugal and Finland. The division into three groups of countries implementing the energy and climate policy introduced by the EU showed that the indicators that differentiate countries to the greatest extent, among the group of selected variables, are greenhouse gas emissions and the energy dependency ratio. Keywords: energy and climate policy, EU countries, synthetic measure. Category of the paper: Research paper.

Published: February 2023

Purpose: The aim of the paper is to identify the process of shaping leaders in a transformed Easter European Countries (EEC) like Poland based on the case study in the IT sector. Design/methodology/approach: A research analysis of the world literature on the subject indicates that these issues have yet to be studied from a long-term perspective. In light of the economic system, the author describes the difference and core attributes for emerging leaders. The author uses the case study of the two IT leading companies and their leaders from roots up to final mergers and acquisitions of each other. Findings: The case study shows that in a long-term perspective the key role is played by the founders based on grounded education, experience, embodied entrepreneurship attitudes, ethics, openness for innovations, independence of unclear relations, and mission are crucial to developing with success the company. Research limitations/implications: The research covers only case studies so that it could be extrapolated to prominent players in specific sectors for companies with the activity of more than ten or even 20 years on the market. Practical implications: The research could be used for training or teaching courses related to MBA, postgraduates, or management program study. Based on the review, the other companies can measure the risk with new potential countries in their early stage of new free markets. The leadership model could be duplicated so that marker analysts and decision-makers could conduct an in-depth study about the leaders in certain countries. The in-depth collaborations should have a long-term perspective with a clear and correct leader and/or founder. The students should consider working in companies with solid leadership ethics to build their prospectus careers. Social implications: The public organization and authorities should cooperate and take a donation from ethical companies and leaders. Hiding support from ethical leaders/founders could be taken without obligations. Donations do not mean even PR. Originality/value: This review emphasizes that becoming a leader means possessing skills that should be shaped during education and even socialization. Leaders could cover their unethical behavior or incompetence to became a manager, but it would provide a huge, postponed on time disaster for the company. The paper is addressed to all potential and present leaders, including students, during their study. Keywords: company survival factors, education, leadership, mergers&acquisitions.

Pada musim pandemi virus COVID-19 seperti ini, masih banyak masyarakat yang cenderung kurang memiliki kesadaran dalam mematuhi protokol kesehatan, terutama dalam hal berkerumun dan menjaga kebersihan tangan. Inovasi tempat cuci tangan saat ini sudah banyak dibuat  di tempat-tempat wisata, toilet restoran, mall, dan bahkan di tempat ibadah. Namun, disaat musim pandemi COVID-19 saat ini, apakah penempatan dan alat tersebut sudah dapat memutus tali penyebaran virus tersebut? Jawabannya adalah masih belum cukup, dikarenakan tempat cuci tangan tersebut masih banyak tersentuh oleh tangan. Meskipun sudah ada yang menggunakan tempat cuci tangan secara otomatis atau touchless, namun pembelian alat tersebut cukup mahal di kalangan masyarakat sekitar. Oleh sebab itu, pada proyek ini kami bermaksud memutus tali penyebaran virus corona, dengan melakukan perancangan wastafel tempat cuci tangan touchless yang ekonomis. Kemudian, setelah alat tersebut selesai dibuat, proses hibah kepada pihak yang memerlukan, yaitu SMK Global Prima di Tambun Utara Kabupaten Bekasi, dilakukan. Meskipun dalam skala yang kecil, kami berharap usaha ini dapat bermanfaat bagi mahasiswa yang terlibat, kepada mitra SMK Global Prima, serta masyarakat pada umumnya. Kegiatan pengabdian masyarakat ini menghasilkan sebuah rancangan mesin cuci tangan touchless, dirancang secara mandiri dan in-house, dan sudah dapat digunakan di SMK Global Prima Kabupaten Bekasi. Meskipun skalanya kecil, namun demikian kegiatan ini sudah mampu memberikan manfaat bagi mitra yaitu SMK Global Prima dalam mempraktikan cuci tangan dengan sabun, yang mana hal ini sangatlah penting di masa pandemic demi mencegah penyebaran virus COVID-19.

Published: February 2023

The purpose of this research is to examine the impact of organizational identification and organizational culture on team success. The universe of the research is the 18 teams in the TFF 1. League. The sample of the study consisted of 324 people from 14 teams who agreed to participate voluntarily in the study. A mixed method model was used in the research. In order to measure the organizational identification levels of the participants, the "Organizational Identification Scale" developed by Mael and Ashforth (1989,1992) was utilized to evaluate the organizational culture levels, and the "Organization Culture Assesment Instrument" developed by Cameron and Quinn (1999-2006) was used as well. According to the quantitative analysis results of the research, the concept of organizational identification has no statistical effect on team success. In terms of organizational culture, apart from Clan culture, the sub-dimensions of Market, Hierarchy and Adhocracy cultures were also found to have an impact on team success. It was concluded that the quantitative and qualitative data used in the research support each other.

El estudio del patrimonio industrial en España: cincuenta años de análisis sobre el legado de la industrialización contemporánea (1972-2022)
Authors: Andrés López Gonzalo , Soria Cáceres Carlos Hugo
Published: February 2023

En 2022 se cumplen cincuenta años de la aprobación de la Convención sobre la protección del Patrimonio Mundial de UNESCO, efeméride que marcó el inicio de la consideración reciente del patrimonio cultural. Durante este periodo el patrimonio industrial se ha ido constituyendo como un asunto relevante en los estudios científicos españoles, pero condicionado por su conceptualización difusa, en el marco de una disciplina controvertida -la Arqueología Industrial- y con un objeto de estudio de compleja delimitación metodológica, cronológica y temática. En este contexto, la investigación científica sobre el legado de la industrialización contemporánea en España ha crecido exponencialmente durante las últimas décadas y arroja interesantes conclusiones sobre el carácter de los distintos estudios, su distribución territorial y temática o las diversas ramas de conocimiento que han participado en este proceso. Este trabajo realiza un estudio bibliométrico sobre las más de 1.600 obras publicadas sobre esta cuestión en estos cincuenta años y permite obtener resultados acerca de cómo, cuándo y desde qué perspectivas se ha abordado el estudio del patrimonio industrial español.
Xoclán: Reconstrucción Urbana de una Ciudad Maya en un Contexto Urbanizado
Authors: Carosi Gaia
Published: February 2023

Habitada desde el Preclásico Medio, Xoclán se desarrolló como centro urbano a partir del Clásico Temprano. El actual parque arqueológico cuenta 52 hectáreas e incluye el área cívico-ceremonial y algunas otras plataformas, mientras que las restantes estructuras que constituyeron parte de la ciudad antigua fueron involucradas en la reciente obra de ampliación de Mérida y muchas han sido destruidas para permitir la construcción de nuevos edificios. A través del presente estudio, fue posible identificar a otros barrios, afuera del parque, que fueron parte del sitio y que se encuentran ahora bajo el asfalto moderno, proponer hipótesis de sus funciones y definir la cronología de desarrollo de la ciudad, llegando - por lo que sea posible - a reconstruir los límites del asentamiento, que alcanzaron al menos un área de 9 kilómetros cuadrados. Finalmente, se presenta un enfoque de lo que pasó después, y de las varias fases de utilizo que afectaron la zona y su patrimonio.
