Adaptive Multi-level Backward Tracking for Sequential Feature Selection
Authors: Chotchantarakun Knitchepon , Sornil Ohm
Published: July 2021

In the past few decades, the large amount of available data has become a major challenge in data mining and machine learning. Feature selection is a significant preprocessing step for selecting the most informative features by removing irrelevant and redundant features, especially for large datasets. These selected features play an important role in information searching and enhancing the performance of machine learning models. In this research, we propose a new technique called One-level Forward Multi-level Backward Selection (OFMB). The proposed algorithm consists of two phases. The first phase aims to create preliminarily selected subsets. The second phase provides an improvement on the previous result by an adaptive multi-level backward searching technique. Hence, the idea is to apply an improvement step during the feature addition and an adaptive search method on the backtracking step. We have tested our algorithm on twelve standard UCI datasets based on k-nearest neighbor and naive Bayes classifiers. Their accuracy was then compared with some popular methods. OFMB showed better results than the other sequential forward searching techniques for most of the tested datasets.

The aim of this research was to reveal and explore the characteristics of Balinese dance maestros by analyzing silhouette sequence patterns of Balinese dance movements. A method and complete scheme for the extraction and construction of silhouette features of Balinese dance movements are proposed to enable performing quantitative analysis of Balinese dance movement patterns. Two different feature extraction methods, namely the Histogram of Gradient (HoG) feature and the Scale Invariant Features Transform (SIFT) descriptor, were used to build the final feature, called the Bag of Visual Movement (BoVM) feature. This research also makes a technical contribution with the proposal of quantifying measures to analyze the movement patterns of Balinese dances and to create the profile and characteristics of dance maestros/creators. Eight Balinese dances from three different Balinese dance maestros were analyzed in this work. Based on the experimental results, the proposed method was able to visually detect and extract patterns from silhouette sequences of Balinese dance movements. Quantitatively, the pattern measures for profiling of Balinese dances and maestros revealed a number of significant characteristics of different dances and different maestros.

Due to the health effects of ammonia as an environmental pollutant, such as its odor, corrosion, algae phenomenon, etc., a method should be adopted to remove it from wastewater. In this study, removal of ammonia from hypothetical wastewater was investigated using adsorption on SWCNTs. The Design-Expert software was used to design the experiments and optimize the parameters that are effective in the adsorption performance of carbon nanotubes (CNTs), such as contact time, adsorbent dosage, pH, temperature, and ammonia concentration. The results revealed that the maximum adsorption with a performance of 90% was attained at a pH of 9.5. In addition, the adsorption performance was enhanced by increasing adsorption time and adsorbent dosage. Furthermore, increasing the temperature and the adsorbate quantity led to a decrease in the adsorption performance.

Novel Application of Fast Simulated Annealing Method in Brushless Motor Drive (BLMD) Dynamical Parameter Identification for Electric Vehicle Propulsion
Authors: A. Guinee Richard
Published: July 2021

Permanent magnet brushless motor drives (BLMD) are extensively used in electric vehicle (EV) propulsion systems because of their high power and torque to weight ratio, virtually maintenance free operation with precision control of torque, speed and position. An accurate dynamical parameter identification strategy is an essential feature in the adaptive control of such BLMD-EV systems where sensorless current feedback is employed for reliable torque control, with multi-modal penalty cost surfaces, in EV high performance tracking and target ranging. Application of the classical Powell Conjugate Direction optimization method is first discussed and its inaccuracy in dynamical parameter identification is illustrated for multimodal cost surfaces. This is used for comparison with the more accurate Fast Simulated Annealing/Diffusion (FSD) method, presented here, in terms of the returned parameter estimates. Details of the FSD development and application to the BLMD parameter estimation problem based on the minimum quantized parameter step sizes from noise considerations are provided. The accuracy of global parameter convergence estimates returned, cost function evaluation and the algorithm run time are presented. Validation of the FSD identification strategy is provided by excellent correlation of BLMD model simulation trace coherence with experimental test data at the optimal estimates and from cost surface simulation.

Published: July 2021

The deployment of 4G/LTE (Long Term Evolution) mobile network has solved the major challenge of high capacities, to build real broadband mobile Internet. This was possible mainly through very strong physical layer and flexible network architecture. However, the bandwidth hungry services have been developed in unprecedented way, such as virtual reality (VR), augmented reality (AR), etc. Furthermore, mobile networks are facing other new services with extremely demand of higher reliability and almost zero-latency performance, like vehicle communications or Internet-of-Vehicles (IoV). Using new radio interface based on massive MIMO, 5G has overcame some of these challenges. In addition, the adoption of software defend networks (SDN) and network function virtualization (NFV) has added a higher degree of flexibility allowing the operators to support very demanding services from different vertical markets. However, network operators are forced to consider a higher level of intelligence in their networks, in order to deeply and accurately learn the operating environment and users behaviors and needs. It is also important to forecast their evolution to build a pro-actively and efficiently (self-) updatable network. In this chapter, we describe the role of artificial intelligence and machine learning in 5G and beyond, to build cost-effective and adaptable performing next generation mobile network. Some practical use cases of AI/ML in network life cycle are discussed.
Making Soft Skills a Part of the Curriculum of Healthcare Studies
Authors: Dolev Niva , Naamati-Schneider Lior , Meirovich Adaya
Published: July 2021

In recent decades, it has been increasingly recognized that soft skills play an important role in healthcare education and must be developed alongside other professional skills. Furthermore, the contribution of emotional intelligence (EI) to the ability to adapt to the changing environment of the 21st century has been widely agreed upon. Yet, despite these findings, social–emotional intelligence (SEI) and related skills skills are not widely developed in healthcare education settings, and if at all, only in a limited way. The present chapter presents a model and a methodological tool (SE-SD) for the development of social–emotional skills (SEI) as part of existing healthcare curricula, applying a broad view of the healthcare professions and associated skills. Soft, social–emotional, skills are positioned as a relevant and integral part of healthcare courses, thereby avoiding the need for significant changes in existing curricula. The SEI development process is implemented in three stages: preparation, action and assessment. The tool allows learners to embark on a self-directed, yet supervised, learning and development process, and can be applied to a single course or through the entire study program. The incorporation of a soft skill development process into healthcare education programs could help health systems to adapt and to cope better with the challenges of the 21st century, both present and future.

The study is devoted to a very urgent and acute problem for Georgia – remediation/restoration of the arsenic (As) mining and storage sites. The approach of a given work is based on using capabilities of nature itself, which has a great adaptive potential to chemical environmental pollution. The aim of the study is to identify the bacterial strains from the endemic soil microbiota, characteristic to a specific localization of arsenic contaminated sites and able to resist to the toxicant. To determine the level of arsenic contamination, soil samples have been analyzed using Inductively Coupled Plasma - Optical Emission Spectrometry method. The distribution of arsenic in soil samples splits them into categories according to the degree of contamination, ranging from 50 ppm to 13000 ppm. The local bacteria community has been studied using conventional cultivation method along with modern method of bioindication – a biochip. The low density biochip contains the relevant probes for the identification of the bacterial consortium in soil microbiota. Chemical and microbiological analysis was based on the standards and methodologies developed by International Standards Organizations – ISO and Environmental Protection Agency – EPA. It is prospected that bioremediation can become essential part of remediation against arsenic pollution in the context of circular economy.

Published: July 2021

Background: This study aimed to assess the correlation between the internal jugular vein/common carotid artery (IJV/CCA) cross-sectional area (CSA) ratio and the inferior vena cava (IVC) diameter as non-invasive techniques for the assessment of intravascular volume. Methods: The study samples included 35 adult patients of both sexes (age range: 20 - 60 years) according to the criteria of the American Society of Anaesthesiology (ASA) physical status II - III, who were admitted to the surgical intensive care unit (SICU) after major surgeries for the assessment of intravascular volume status. Results: There was a positive correlation between the IJV/CCA CSA ratio and the IVC maximum and minimum diameter before and after fluid infusion (r = 0.923, P < 0.001 and r = 0.390, P = 0.021, respectively) and between the IJV/CCA CSA ratio at inspiration and the IVC minimum diameter before and after fluid infusion (r = 0.605, P < 0.001 and r = 0.496, P < 0.001, respectively). The sensitivity and specificity analysis of the IJV/CCA CSA during inspiration after fluid correction to predict a central venous pressure (CVP) of 8 - 12 cmH2O showed that at a ratio of 2.56, the highest sensitivity was 56.5%, and the specificity was 83.3%; at a ratio of 2.58, the highest sensitivity was 65.2% and the specificity was 75%. During expiration, at a ratio of 2.62, the highest sensitivity was 52.2%, and the specificity was 67%; and at a ratio of 2.65, the sensitivity was 56.5%, and the specificity was 50%. Conclusions: The assessment of the IJV/CCA CSA ratio using bedside ultrasound could be a non-invasive tool for the evaluation of intravascular volume status in spontaneously breathing adult patients after major surgeries.

Ancestral foxes at the gates of Europe: the Pliocene fox from Çalta-1 (Turkey) and their relationships with Asian and European Plio-Pleistocene foxes
Authors: BARTOLINI-LUCENTI Saverio , Joan MADURELL-MALAPEIRA undefined
Published: July 2021

The Pliocene record of genus Vulpes Frisch, 1775 in Eurasia is scarce, coming from few sparse localities. The lack of a comprehensive and integrated revision led to the description of numerous different taxa, often only tentatively related to extant species but not with one another. Çalta-1 is an important Pliocene site located in the Anatolian region of Turkey, dated to 4.0 Ma. In the present review, we reappraise the interesting record of Vulpes galatica Ginsburg, 1998. Morphological and ­morphometric evidence suggests a strong similarity between this taxon and the early Late Pliocene V. beihaiensis Qiu & Tedford, 1990, recovered from the Chinese Yushe Basin. Such evidence favors the parsimonious interpretation of synonymy between the two species, under the name V. beihaiensis. This hypothesis opens a new interpretation on the biogeography of the Pliocene-Early Pleistocene foxes of Eurasia. Vulpes beihaiensis links the Asian and European records, with its affinity to V. ­alopecoides (Del Campana, 1913) and, eventually, to the extant red fox (Vulpes vulpes (Linnaeus, 1758)).
An Improved Procedure for Strongly Coupled Prediction of Sailing Yacht Performance
Authors: Persson A. , Larsson L. , Finnsgård C.
Published: July 2021

In this paper, an improved procedure for strongly coupled prediction of sailing yacht performance is developed. The procedure uses 3D RANS CFD to compute the hydrodynamic forces. When coupled to a rigid body motion solver and a sail force model, along with a rudder control algorithm, this allows sailing yacht performance to be predicted within CFD software. The procedure provides improved convergence when compared to a previously published method. The grid motion scheme, partially using overset grid techniques, means that correct alignment between the free surface and the background grid is ensured even at large heel angles. The capabilities are demonstrated with performance predictions for the SYRF 14 m yacht, at one true wind speed, over a range of true wind angles, with up- and downwind sailsets. The results are compared to predictions from the ORC-VPP for a yacht with similar main particulars.

An Investigation into Execution Delays During Naval Vessels’ Availabilities
Authors: Caprio Joseph L. , Jacobs Patricia , Whitcomb Clifford
Published: July 2021

The U.S. Naval Shipyards’ schedules revolve around the planning and execution of Naval vessel “availabilities,” essential maintenance periods during the life of a vessel with the purpose of maintaining and improving the operational readiness and its fighting ability. Because of the high operational tempo for Naval vessels today, the four public Naval shipyards are continually challenged to complete depot-level availabilities on schedule. In order to support the completion of availabilities in a timely manner, this article presents a summary of execution delays (known as work stoppages), and an analysis on the impact of work stoppages during the execution phase. The work stoppage data are summarized to display possible trends based on the mean length and quantity of work stoppages across multiple availabilities, and possible predictors of availability lateness using a timed based metric are further investigated. The analysis of the data suggests that although no simple association exist between the quantity or length of work stoppage and the lateness of an availability, availabilities that finish on schedule tend to have had fewer work stoppages before the start of the availability as compared to the later finishing availabilities, signifying the importance of a complete and thoroughly supported availability plan. This study assists the Naval shipyard leadership in understanding a contributing factor to availability lateness and can be applied to the shipyard maintenance community in which delays are experienced throughout a project.
Analytical Approach to a Two-Stage Queueing Network for the Planning of Outfitting Processes in Shipbuilding
Authors: Dong Fang , Deglise-Hawkinson Jivan , Van Oyen Mark P. , Singer David J.
Published: July 2021

As an important part of shipbuilding, outfitting can represent a major portion of the material cost as well as the construction time of a vessel. However, due to disturbances caused by unexpected delays, system variations, and technological constraints, scheduling of outfitting processes is therefore complex and can lead to major construction delays. To improve the shipbuilding system efficiency in the presence of variation, a two-stage strategic level outfitting planning model has been developed. The results of the model provide the optimal percentage of outfitting work that should be completed at each stage given the introduction of variation. The model presented can be used as a benchmark for current ship outfitting management decisions.
High Deposition Welding for Shipbuilding
Authors: Jones Jerald E. , Rhoades Valerie L. , Madden Stephen K.
Published: July 2021

A new welding process has been developed which uses a hybrid concept. A portable induction coil is operated ahead of the arc welding torch, and heats the surfaces of the weld to near the melting point. Then the heat generated by the welding arc is primarily used only to melt the welding wire. The process operates at speeds of 2-3 times the speed of conventional arc welding and has the added advantage of substantially reducing weld distortion. The need for weld joint preparation, such as beveling, is eliminated for butt joints, even in fairly thick parts, which dramatically improves welding productivity.
Stochastic Assessment and Applications for Welding Shrinkage Impact on Production Cost
Authors: Heo H. Y. , Youn D. H. , Chung H.
Published: July 2021

Since ship hull blocks are constructed by assembling numerous intermediate parts, negligible dimensional variations in the parts can easily accumulate to cause serious misalignment in block erection stage. Considering the welding – the primary joining process in ship production which inherently causes distortions, the quality of block’s dimensional variations during the assembly would deteriorate even faster. Thinking that the intermediate products with low dimensional quality in the ship production are not scrapped but reworked, the productivity of each workstation greatly depends on the dimensional quality of these dimensionally critical intermediate products. Reworks such as recutting, mechanical and/or thermal correction against misalignment, excessive welding for wide gap and thermal straightening are commonly subsequently increases the total production cost.

One of the major dimensional accuracy control activities is the shrinkage margin design. The optimal length of excess edge is assigned to plates in order to compensate welding shrinkage. In the past, the welding shrinkage is predicted based mostly on the empirical formula or just designer's experience, so the accuracy of the assigned was relatively poor and could not effectively help reducing non-value-added rework activities. The simplified margin calculation procedure could not consider the welding sequence as well as process variations such as welding heat input.

This work aims to develop the optimal shrinkage margin calculation system for dimensional quality improvement. The proposed system calculates the optimal shrinkage margin using computer-aided engineering toolsets based on finite element analysis as well as design point searching procedure adopting the quality loss function and statistical values considering shrinkage variation values during welding.

The developed scheme improves the accuracy control procedure in the ship production process thus enhance competitiveness of shipbuilders in dimensional accuracy technology by minimizing the accuracy impact on productivity.

PORODIČNA AFEKTIVNA VEZANOST KOD SUICIDALNIH PACIJENATA
Authors: Samardžić Snežana
Published: July 2021

Rad se oslanja na Bowlby-jevu teoriju afektivnog vezivanja, u skladu sa pretpostavkom da kvalitet afektivne vezanosti u detinjstvu predviđa kasnije psihološko funkcionisanje osobe, te da samoubistvo, kao autodestruktivni čin, može biti posledica nesigurne vezanosti. Cilj ovog rada bio je utvrditi da li se pacijenti, koji su ispoljili suicidalno ponašanje, češće svrstavaju u neki od nesigurnih obrazaca vezanosti, u odnosu na zdrave ispitanike bez suicidalnih tendencija. Istraživanje je provedeno u Specijalnoj bolnici za psihijatriju u Sokocu, a uzorak je činilo 80 ispitanika muškog pola, svrstanih u dve grupe: grupu suicidalnih pacijenata (N1=40) i grupu zdravih, nesuicidalnih ispitanika (N=40). Kratkim, strukturiranim upitnikom napravljenim za potrebe ovog istraživanja, prikupljeni su podaci o subjektivnom doživljaju majke i oca. Ispitivanje porodične afektivne vezanosti provedeno je modifikovanim Brennanovim upitnikom, za procenjivanje porodične afektivne vezanosti (Stefanović-Stanojević, 2005). Za testiranje razlika između grupa korišćen je χ² test. Rezultati pokazuju da postoji statistički značajna razlika između ispitivanih grupa i to tako, da su se ispitanici iz grupe suicidalnih, značajno češće svrstavali u nesigurno-okupirani i nesigurno-plašljivi obrazac vezivanja (χ²(3)=23,928; p=0,000) i češće su odrastali uz prezaštićujuću, agresivnu ili majku sa psihičkim problemima (2(3)=28,976; p=0,000), dok razlike u odnosu na doživljaj oca nemaju statističku značajnost (2(2)=3,436; p=0,179).

CONFLICT OF A MEMORY CULTURE IN WESTERN BALKANS
Authors: Vuković Đorđe
Published: July 2021

Cultures of remembrance that are officially affirmed by national elites in the Western Balkan countries, that is in the former Yugoslavia, are a source of ongoing conflict. Various collective memories and mutually antagonized interpretations of the past, show that Croats, Serbs, Bosnians, Macedonians, Montenegrins and others who lived together for centuries and decades within a single state, after all interpret and remember their common history in completely different ways. Their social narratives about the past and dominant cultures of memory are predominantly selective, one-sided, intolerant, exclusive. After a long time, they lived together members of different ethnic, religious and national backgrounds and their historically unfinished and unsuccessful attempt to form a common Yugoslav culture and unique Yugoslav identity, a difficult civil war occurred, ethno-nationalism escalated, and people who were very close and very similar to one another, tried to create as much difference and distance between themselves through violence. All national communities that participated in the wars of the 1990s, emphasized defending national culture as one of their main tasks. The warring parties sought to destroy everything that reminded them that different people, their neighbors and friends of a different religion were living there. Today, three decades after these conflicts, they are still prisoners of their attitude to history. The culture nevertheless brings them together and inspires them to understand themselves more and to cooperate better.

Razvoj informacionih tehnologija, stvaranje kompjuterskih mreža, a posebno „mreže svih mreža“ - Interneta, omogućili su novi način komuniciranja, koji karakterizira interaktivnost, kao differentia speciffica novih u odnosu na tradicionalne medije masovnog komuniciranja. Kao što je primijetio John Quaterman: „Jedan od razloga za popularnost kompjuterskog medija komuniciranja, jest upravo taj, što ljude spaja, povezuje direktno, bez posredstva uspostavljenih birokratskih hijerarhija. Ovo je za neke ljude izvor novih briga.“

Empirijski nalazi pokazuju da Bosna i Hercegovina nije društvo u kojem su žene rado viđene na liderskim pozicijama. Međutim, u isto vrijeme je evidentno i značajnije učešće žena u sferama politike i profesionalnog djelovanja. Možda više nego drugim političkim faktorima, ženama angažovanim u sferi politike su potrebni kvalitetni, transparentni i pravovremeni odnosi sa javnošću. Stoga je pravo vrijeme da se postave pitanja imajući u vidu upravo subpopulaciju žena u politici u Bosni i Hercegovini: Koliki je uistinu značaj komuniciranja s javnošću u Bosni i Hercegovini danas? Kako i na koji način komunicitati? Ova i slična pitanja su razmatrana na ukupno osam sesija u okviru Edukacija predstavnica političkih partija i izabranih predstavnica vlast u BiH koje je inicirao i realizovao Nezavisni univerzitet Banja Luka, od kojih je šest realizovano pod pokroviteljstvom Norveške ambasade u BiH. Ovaj rad ima za cilj da uz analizu predoči konkretna iskustva na polju provođenja projekta, metodologije rada, ličnih impresija polaznica i efekte same edukacije. Rad obuhvata analizu šest šestodnevnih edukacija koje su realizovane pod pokroviteljstvom Norveške ambasade u BiH u periodu od aprila 2013. do februara 2014. godine, a koje su pohađale 434 učesnice. U razmatranju rezultata je primijenjena tehnika triangulacije (kombinovanih metoda). Na osnovu analize ukupnih rezultata program Edukacije može da, pored obrazovne, ima i praktičnu vrijednost.

Subplate neurons (SPNs) are thought to play a role in nascent sensory processing in neocortex. To better understand how heterogeneity within this population relates to emergent function, we investigated the synaptic connectivity of Lpar1-EGFP SPNs through the first postnatal week in whisker somatosensory cortex (S1BF). These SPNs comprise of two morphological subtypes: fusiform SPNs with local axons and pyramidal SPNs with axons that extend through the marginal zone. The former receive translaminar synaptic input up until the emergence of the whisker barrels, a timepoint coincident with significant cell death. In contrast, pyramidal SPNs receive local input from the subplate at early ages but then – during the later time window – acquire input from overlying cortex. Combined electrical and optogenetic activation of thalamic afferents identified that Lpar1-EGFP SPNs receive sparse thalamic innervation. These data reveal components of the postnatal network that interpret sparse thalamic input to direct the emergent columnar structure of S1BF.
Distinct forms of synaptic plasticity during ascending vs descending control of medial olivocochlear efferent neurons
Authors: Romero Gabriel E , Trussell Laurence O
Published: July 2021

Activity in each brain region is shaped by the convergence of ascending and descending axonal pathways, and the balance and characteristics of these determine the neural output. The medial olivocochlear (MOC) efferent system is part of a reflex arc that critically controls auditory sensitivity. Multiple central pathways contact MOC neurons, raising the question of how a reflex arc could be engaged by diverse inputs. We examined functional properties of synapses onto brainstem MOC neurons from ascending (ventral cochlear nucleus, VCN) and descending (inferior colliculus, IC) sources in mice using an optogenetic approach. We found that these pathways exhibited opposing forms of short-term plasticity, with the VCN input showing depression and the IC input showing marked facilitation. By using a conductance-clamp approach, we found that combinations of facilitating and depressing inputs enabled firing of MOC neurons over a surprisingly wide dynamic range, suggesting an essential role for descending signaling to a brainstem nucleus.

Faithful segregation of bacterial chromosomes relies on the ParABS partitioning system and the SMC complex. In this work, we used single-molecule techniques to investigate the role of cytidine triphosphate (CTP) binding and hydrolysis in the critical interaction between centromere-like parS DNA sequences and the ParB CTPase. Using a combined optical tweezers confocal microscope, we observe the specific interaction of ParB with parS directly. Binding around parS is enhanced by the presence of CTP or the non-hydrolysable analogue CTPγS. However, ParB proteins are also detected at a lower density in distal non-specific DNA. This requires the presence of a parS loading site and is prevented by protein roadblocks, consistent with one-dimensional diffusion by a sliding clamp. ParB diffusion on non-specific DNA is corroborated by direct visualization and quantification of movement of individual quantum dot labelled ParB. Magnetic tweezers experiments show that the spreading activity, which has an absolute requirement for CTP binding but not hydrolysis, results in the condensation of parS-containing DNA molecules at low nanomolar protein concentrations.

The E2F transcription factors play a critical role in controlling cell fate. In Drosophila, the inactivation of E2F in either muscle or fat body results in lethality, suggesting an essential function for E2F in these tissues. However, the cellular and organismal consequences of inactivating E2F in these tissues are not fully understood. Here, we show that the E2F loss exerts both tissue-intrinsic and systemic effects. The proteomic profiling of E2F-deficient muscle and fat body revealed that E2F regulates carbohydrate metabolism, a conclusion further supported by metabolomic profiling. Intriguingly, animals with E2F-deficient fat body had a lower level of circulating trehalose and reduced storage of fat. Strikingly, a sugar supplement was sufficient to restore both trehalose and fat levels, and subsequently rescued animal lethality. Collectively, our data highlight the unexpected complexity of E2F mutant phenotype, which is a result of combining both tissue-specific and systemic changes that contribute to animal development.
