This study aims to understand the meaning and find the cultural concept of "Feng Shui" in the concept of spatial planning practices of Chinese communities in Indonesia. This study uses a phenomenological approach regarding the meaning and cultural values of "feng shui" in the spatial planning practices of Chinese communities in Indonesia. The research findings indicate that there is symbolic interaction in interpersonal communication between consultants and service users (patients). In this study, researchers collected data using observation and in-depth interviews to obtain research results. The research results obtained by researchers are the symbolic interactions that occur in the "feng shui" culture in the spatial practice of Chinese community buildings in Indonesia which have several stages, namely actions, namely consultant service users accept the presence of "feng shui" in their midst because it brings damage positive for the community, gestures that is, people interpret the movements of the practice of "feng shui" when possessed by spirits from gods who are trusted to provide solutions, significant symbols, namely symbols contained in the practice of "feng shui" which can be seen from the tools used during practice, mind in the process of consulting the practice of "feng shui" is closely related to symbols and language reflected in how the symbols and language that "feng shui" consultants use to service users and vice versa, self is the ability to self-reflect each individual from the assessment of the point of view or opinion of others.

Published: June 2023

The focus of this study was to investigate the effectiveness of Gist and Graphic Organizers in teaching reading to students with different levels of vocabulary proficiency. This study used a quasi-experimental methodology with a 2x2 factorial design to examine university-level English language learners. Two experimental subjects were involved. Gist and Graphic Organizer materials were used as instructional tools for data collection. Additionally, an observation was made to validate the data findings. According to the research findings, Gist and Graphic Organizers were helpful in teaching reading to students with different vocabulary competence levels. However, the results suggested that the Gist technique benefits both pupils with high and low vocabulary skills. Observation also revealed that students found the Gist technique more engaging and participatory. The lexical proficiency of students had a substantial impact on instructional materials, mainly when the Gist technique was applied. It has a significant impact on the reading comprehension of students. In teaching reading comprehension, the Gist method was adequate for students with a high vocabulary competency, while graphics Organizers was adequate for learner with a low vocabulary proficiency.

Published: June 2023

Entrepreneurship in the nursing field is still rising giving greater opportunity for these nursing entrepreneurs. However, nurses need to identify the obstacles and the supports so that their businesses will run well and succeed. To identify the hindering and supporting factors for nurses in entrepreneurship. This study was a narrative review with literature research using electronic databases, which included Science Direct and PubMed between 2011-2021. The framework from the European Medical Writers Association developed by Ferrari was used to guide the study From the total of 11 identified and analyzed literatures, there were seven hindering factors (fear; knowledge and skill; prior working culture experience; decision-making policy and regulations; health insurance, colleague jealousy; and unprofessional attitudes) and two supporting factors (knowledge and skills; ability to seek opportunities). Conducting entrepreneurship in nursing still faces several obstacles but also has some supports, and therefore can be done by developing nurses’ self-potentials and professional attitudes.

Published: June 2023

The enthusiasm for maintaining health has increased in line with the Covid-19 pandemic, though they have to pay the higher price. Therefore, study aims to determine changes in people's behavior in consuming organic vegetables due to Covid-19, willingness to pay (WTP) and factors that influence. The research was conducted in three stages--descriptive socio-demographic factors, calculation of WTP with the Contingent Valuation Method approach and SEM (Structural Equation Modeling) analysis. Based on 155 respondents who determined by Slovin formula and accidental sampling technique. The study showed that consumers had a higher WTP for various types of organic vegetables, especially spinach, chayote, and kale. However, this WTP is significantly influenced by level of education, type of work and income. Consumer behavior significantly affected WTP for organic vegetables during Covid-19 pandemic. Thus, Covid-19 pandemic provides great potential for an increase in the number of consumption and purchases of organic vegetables.

DOES ENERGY DEMOCRACY AFFECT ECONOMIC GROWTH? EARLY EVIDENCE FROM HIGH INCOME COUNTRIES DURING 1997–2020
Authors: Shabir Maria , Basile Giuseppe , Pazienza Pasquale , De Lucia Caterina
Published: June 2023

In accordance with UN sustainable development policies, this study examines the impact of energy democracy, energy equality, exports, globalization, financial development, and natural resources on economic growth patterns of high-income countries from 1997 to 2020. The study finds evidence of a long-run relationship among variables. Empirical estimations from FMOLS and DOLS models reveal that energy democracy, exports, globalization, and financial resources enhance economic progress, while natural resource consumption provides an opposite effect. This study suggests that high-income countries should promote community-based renewable energy projects and energy-efficient practices as well as implementing an adequate harmonisation of energy democracy policies and processes.
A Census of the TW Hya Association with Gaia*
Authors: Luhman K. L.
Published: June 2023

I have used high-precision photometry and astrometry from the third data release of Gaia to perform a survey for members of the TW Hya association (TWA). I have identified candidate members that appear to share similar kinematics and ages with bona fide members compiled by Gagné et al. (2017), and I have assessed their membership using radial velocities and spectroscopic diagnostics of age from various sources. My new catalog of adopted members contains 67 Gaia sources in 55 systems. The histogram of spectral types for TWA peaks near M5 (∼0.15 M
⊙), resembling the distributions measured for other nearby young associations. The UVW velocities of its members indicate that the association is expanding. The rate of expansion corresponds to an age of

Finally, I have used mid-infrared photometry from the Wide-field Infrared Survey Explorer to check for excess emission from circumstellar disks among the TWA members. Fourteen members have detected disks, all of which have been reported in previous studies. The fraction of members at ≤ M6 (≳0.1 M

Spectroscopic Follow-up of Gaia Exoplanet Candidates: Impostor Binary Stars Invade the Gaia DR3 Astrometric Exoplanet Candidates
Authors: Marcussen Marcus L. , Albrecht Simon H.
Published: June 2023

In this paper, we report on the follow-up of six potential exoplanets detected with Gaia astrometry and provide an overview of what is currently known about the nature of the entire Gaia astrometric exoplanet candidate sample, 72 systems in total. We discuss the primary false-positive scenario for astrometric planet detections: binary systems with alike components that produce small photocenter motions, mimicking exoplanets. These false positives can be identified as double-lined binaries (SB2) through analysis of high-resolution spectra. Doing so we find that three systems, Gaia DR3 1916454200349735680, Gaia DR3 2052469973468984192, and Gaia DR3 5122670101678217728, are indeed near-equal-mass double-star systems rather than exoplanetary systems. The spectra of the other two analyzed systems, HD 40503 and HIP 66074, are consistent with the exoplanet scenario in that no second set of lines can be found in the time series of publicly available high-resolution spectra. However, their Gaia astrometric solutions imply radial-velocity semiamplitudes ∼3 (HD 40503) and ∼15 (HIP 66074) larger than what was observed with ground-based spectrographs. The Gaia astrometry orbital solutions and ground-based radial-velocity measurements exhibit inconsistencies in six out of a total of 12 exoplanet candidate systems where such data are available, primarily due to substantial differences between observed ground-based radial-velocity semiamplitudes and those implied by the Gaia orbits. We investigated various hypotheses as to why this might be the case, and although we found no clear perpetrator, we note that a mismatch in orbital inclination offers the most straightforward explanation.

We present a search for extragalactic fast blue optical transients (FBOTs) during Phase I of the Zwicky Transient Facility (ZTF). We identify 38 candidates with durations above half-maximum light 1 day < t
1/2 < 12 days, of which 28 have blue (g − r ≲ −0.2 mag) colors at peak light. Of the 38 transients (28 FBOTs), 19 (13) can be spectroscopically classified as core-collapse supernovae (SNe): 11 (8) H- or He-rich (Type II/IIb/Ib) SNe, 6 (4) interacting (Type IIn/Ibn) SNe, and 2 (1) H&He-poor (Type Ic/Ic-BL) SNe. Two FBOTs (published previously) had predominantly featureless spectra and luminous radio emission: AT2018lug (The Koala) and AT2020xnd (The Camel). Seven (five) did not have a definitive classification: AT 2020bdh showed tentative broad Hα in emission, and AT 2020bot showed unidentified broad features and was 10 kpc offset from the center of an early-type galaxy. Ten (eight) have no spectroscopic observations or redshift measurements. We present multiwavelength (radio, millimeter, and/or X-ray) observations for five FBOTs (three Type Ibn, one Type IIn/Ibn, one Type IIb). Additionally, we search radio-survey (VLA and ASKAP) data to set limits on the presence of radio emission for 24 of the transients. All X-ray and radio observations resulted in nondetections; we rule out AT2018cow-like X-ray and radio behavior for five FBOTs and more luminous emission (such as that seen in the Camel) for four additional FBOTs. We conclude that exotic transients similar to AT2018cow, the Koala, and the Camel represent a rare subset of FBOTs and use ZTF’s SN classification experiments to measure the rate to be at most 0.1% of the local core-collapse SN rate.
The Roles of Dust Growth in the Temperature Evolution and Snow Line Migration in Magnetically Accreting Protoplanetary Disks
Authors: Kondo Katsushi , Okuzumi Satoshi , Mori Shoji
Published: June 2023

The temperature structure of protoplanetary disks provides an important constraint on where in the disks rocky planets like our own form. Recent nonideal magnetohydrodynamical (MHD) simulations have shown that the internal Joule heating associated with magnetically driven disk accretion is inefficient at heating the disk midplane. A disk temperature model based on the MHD simulations predicts that in a disk around a solar-mass young star, the water snow line can move inside the current Earth’s orbit within 1 Myr after disk formation. However, the efficiency of the internal Joule heating depends on the disk’s ionization and opacity structures, both of which are governed by dust grains. In this study, we investigate these effects by combining the previous temperature model for magnetically accreting disks with a parameterized model for the grain size and vertical distribution. Grain growth enhances the gas ionization fraction and thereby allows Joule heating to occur closer to the midplane. However, growth beyond 10 μm causes a decrease in the disk opacity, leading to a lower midplane temperature. The combination of these two effects results in the midplane temperature being maximized when the grain size is in the range 10–100 μm. Grain growth to millimeter sizes can also delay the snow line’s migration to the 1 au orbit by up to a few million years. We conclude that accounting for dust growth is essential for accurately modeling the snow line evolution and terrestrial planet formation in magnetically accreting protoplanetary disks.
A Tale of Three Dwarfs: No Extreme Cluster Formation in Extreme Star-forming Galaxies

Nearly all current simulations predict that outcomes of the star formation process, such as the fraction of stars that form in bound clusters (Γ), depend on the intensity of star formation activity (ΣSFR) in the host galaxy. The exact shape and strength of the predicted correlations, however, vary from simulation to simulation. Observational results also remain unclear at this time, because most works have mixed estimates made from very young clusters for galaxies with higher ΣSFR with those from older clusters for galaxies with lower ΣSFR. The three blue compact dwarf (BCD) galaxies ESO 185-IG13, ESO 338-IG04, and Haro 11 have played a central role on the observational side because they have some of the highest known ΣSFR and published values of Γ. We present new estimates of Γ for these BCDs in three age intervals (1–10 Myr, 10–100 Myr, 100–400 Myr), based on age-dating, which includes Hα photometry to better discriminate between clusters younger and older than ≈10 Myr. We find significantly lower values for Γ(1–10 Myr) than published previously. The likely reason for the discrepancy is that previous estimates appear to be based on age–reddening results that underestimated ages and overestimated reddening for many clusters, artificially boosting Γ(1–10 Myr). We also find that fewer stars remain in clusters over time, with ≈15%–39% in 1–10 Myr clusters, ≈5%–7% in 10–100 Myr clusters, and ≈1%–2% in 100–400 Myr clusters. We find no evidence that Γ increases with ΣSFR. These results imply that cluster formation efficiency does not vary with star formation intensity in the host galaxy. If confirmed, our results will help guide future assumptions in galaxy-scale simulations of cluster formation and evolution.
Exploring the Observability of Surviving Companions of Stripped-envelope Supernovae: A Case Study of Type Ic SN 2020oi
Authors: Chen 陳 Hsin-Pei 昕霈 , Rau 饒 Shiau-Jie 孝節 , Pan 潘 Kuo-Chuan 國全
Published: June 2023

Stripped-envelope (SE) supernovae (SNe) were considered as the explosions of single massive stars with strong stellar winds, while later observations favor binary origins. One direct piece of evidence to support the binary origins is to find the surviving companions of SE SNe because previous numerical studies suggested that the binary companion should survive the SN impact and could be detectable. Recently, Gagliano et al. reported that the nearby Type Ic SN 2020oi in M100 (∼17.1 Mpc) resulted from a binary system based on the Hubble Space Telescope photometric and spectroscopic observation. Based on the suggested binary properties of SN 2020oi, we conduct 2D hydrodynamics simulations of SN–companion interactions and the subsequent post-impact evolution of the companion. Our results suggest that a surviving companion becomes brighter in 2 orders of magnitude and temporarily redder after the SN impact. The companion might be detectable with the JWST NIRCam short-wavelength channel in a few years. Furthermore, the predicted magnitudes of surviving companions show a significant magnitude gradient around the peak. This could be another indicator to identify the surviving companion from an SE SN.

We discover three new weak pulse components in two known pulsars, one in PSR J0304+1932 and two in PSR J1518+4904. These components are emitted about halfway between the main emission beam and the interpulse beam (beam from the opposite pole). They are separated from their main pulse peak by 99° ± 3° for J0304+1932 and 123.°6 ± 0.°7 (leading) and 93° ± 0.°4 (trailing) for J1518+4904. Their peak-intensity ratios to main pulses are ∼ 0.06% for J0304+1932 and ∼0.17% and ∼0.83% for J1518+4904. We also analyzed the flux fluctuations and profile variations of the emissions for the two pulsars. The results show correlations between the weak pulses and their main pulses, indicating that these emissions come from the same pole. We estimated the emission altitude of these weak pulses and derived a height of about half of the pulsar’s light-cylinder radius. These pulse components are a unique sample of high-altitude emissions from pulsars, and challenge the current pulsar emission models.
Spatial Intermittency of Particle Distribution in Relativistic Plasma Turbulence

We argue that in addition to exhibiting non-Gaussian distributions over energies, particles energized by relativistic turbulence also become highly intermittent in space.

Revisiting the Spectral Energy Correlations of GRBs with Fermi Data. I. Model-wise Properties
Authors: Li Liang
Published: June 2023

Gamma-ray bursts (GRBs) exhibit a diversity of spectra. Several spectral models (e.g., Band, cutoff power law (CPL), and blackbody) and their hybrid versions (e.g., Band+blackbody) have been widely used to fit the observed GRB spectra. Here, we attempt to collect all the bursts detected by Fermi/GBM with known redshifts from 2008 July to 2022 May, having been motivated to (i) provide a parameter catalog independent of the official Fermi/GBM team and (ii) achieve a “clean” model-based GRB spectral energy correlation analysis. A nearly complete GRB sample is created, containing 153 such bursts (136 long GRBs and 17 short GRBs). Using the sample and by performing detailed spectral analysis and model comparisons, we investigate two GRB spectral energy correlations: the correlation of the cosmological rest-frame peak energy (E

) of the ν

The Earliest Stage of Galactic Star Formation

Published: June 2023

Using a recently developed technique to estimate gas temperatures (T
SF) in star-forming regions from large photometric surveys, we propose a diagram, analogous to the Hertzsprung–Russell diagram for individual stars, to probe the evolution of individual galaxies. On this T
SF-sSFR (specific star formation rate) diagram, a small fraction of star-forming galaxies appear to be dominated by different feedback mechanisms than typical star-forming galaxies. These galaxies generically have younger stellar populations and lower stellar masses and increase in relative abundance toward higher redshifts, so we argue that these objects are in an earlier stage of galactic star formation. Further, Hubble observations find that these “core-forming” galaxies also exhibit distinct morphology and that tracks on the T
SF-sSFR diagram are also a morphological sequence. Thus, unlike starburst phases which can be triggered environmentally, these earliest core-forming galaxies appear to be a stage that typical galaxies go through early in their star formation history. We therefore argue that most galaxies first go through a core formation stage, then subsequently disk formation, and finally become quiescent.
Origins of the Evil Eye: M64's Stellar Halo Reveals the Recent Accretion of an SMC-mass Satellite

M64, often called the “Evil Eye” galaxy, is unique among local galaxies. Beyond its dramatic, dusty nucleus, it also hosts an outer gas disk that counter-rotates relative to its stars. The mass of this outer disk is comparable to the gas content of the Small Magellanic Cloud (SMC), prompting the idea that it was likely accreted in a recent minor merger. Yet, detailed follow-up studies of M64's outer disk have shown no evidence of such an event, leading to other interpretations, such as a “flyby” interaction with the distant diffuse satellite Coma P. We present Subaru Hyper Suprime-Cam observations of M64's stellar halo, which resolve its stellar populations and reveal a spectacular radial shell feature, oriented ∼30° relative to the major axis and along the rotation axis of the outer gas disk. The shell is ∼45 kpc southeast of M64, while a similar but more diffuse plume to the northwest extends to >100 kpc. We estimate a stellar mass and metallicity for the southern shell of M
⋆ = 1.80 ± 0.54 × 108
M
⊙ and [M/H] = −1.0, respectively, and a similar mass of 1.42 ± 0.71 × 108
M
⊙ for the northern plume. Taking into account the accreted material in M64's inner disk, we estimate a total stellar mass for the progenitor satellite of M
⋆,prog ≃ 5 × 108
M
⊙. These results suggest that M64 is in the final stages of a minor merger with a gas-rich satellite strikingly similar to the SMC, in which M64's accreted counter-rotating gas originated, and which is responsible for the formation of its dusty inner star-forming disk.
Climate change and jump dispersal drive invasion of the Rosy Wolfsnail (Euglandina rosea) in the United States
Authors: Mills Dana , McKinney Michael
Published: June 2023

The rosy wolfsnail (E. rosea) is a carnivorous, highly detrimental invader in many parts of the world. While its negative impact on endemic island mollusk populations has been well documented, little is known about its range expansion in North America, where populations are not constrained by oceanic barriers. In this study, we present three compelling lines of evidence indicating significant ongoing and projected geographic range expansion of E. rosea: 1) we analyze the current range using data from iNaturalist, 2) we report on the demographics and persistence of an isolated extra-limital satellite population in Nashville, Tennessee since its discovery in 2006 and 3) we employ a predictive ecological model that incorporates environmental variables indicating that the range expansion will continue into the central US well beyond its present range limits. The findings of this study shed light on the underlying mechanisms behind the invasion of this species. First, the invasion is frequently associated with jump dispersal events, which are often linked to horticultural and landscaping activities. Second, the establishment and proliferation of satellite populations are facilitated by common landscape management practices, such as irrigation, as well as the urban heat island effect (UHI). Third, there is a synergistic interplay between the UHI effect and climate change which accelerates the range expansion via global warming.

Published: June 2023

The Galápagos ant fauna has long been understudied, with the last taxonomic summary being published almost a century ago. Here, we provide a comprehensive and updated overview of the known ant species of the Galápagos Islands with updated species distributions. The list is based on an extensive review of literature, the identification of more than 382,023 specimens deposited in different entomological collections, as well as recent expeditions to the islands. The fauna is composed of five subfamilies (Dolichoderinae, Dorilynae, Formicinae, Myrmicinae and Ponerinae), 22 genera and 53 species, though 3 of these species are considered dubious records. Finally, we provide an illustrated identification key of the species in the archipelago.

The present paper describes and illustrates six new species of Pediopsoides (Pediopsoides) namely, P. (P.) ailaoshanensis Li & Dai, sp. nov., P. (P.) quadrispinosus Li & Dai, sp. nov., P. (P.) flavus Li & Dai, sp. nov., and P. (P.) pianmaensis Li & Dai, sp. nov. all collected in Yunnan Province, southwestern China, P. (P.) maoershanensis Li & Dai, sp. nov., found in Guangxi Autonomous Region, southern China, and P. (P.) huangi Li & Dai sp. nov., from Taiwan, previously incorrectly recorded as a new name by Li & Dai, 2018 in Dai et al. 2018: 203 for P. (P.) femorata Huang & Viraktamath, 1993 (nec Pediopsis femorata Hamilton, 1980). Two new junior synonyms of Sispocnis Anufriev, 1967 are proposed, i.e., Digitalis Liu & Zhang, 2002, syn. nov. and Neosispocnis Dmitriev, 2020, syn. nov.

Non–English-speaking patients face increased communication barriers when undergoing total joint arthroplasty (TJA). Surgeons may learn or have proficiency in languages spoken among their patients to improve communication. This study investigated the effect of surgeon–patient language concordance on outcomes after TJA. We conducted a single-institution, retrospective review of patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) whose preferred language was not English. Patients were stratified based on whether their surgeon spoke their preferred language (language concordant [LC]) or not (language discordant [LD]). Baseline characteristics, length of stay, discharge disposition, revision rate, readmission rate, and patient-reported outcomes (Knee injury and Osteoarthritis Outcome Score for Joint Replacement [KOOS, JR], Hip disability and Osteoarthritis Outcome Score for Joint Replacement [HOOS, JR], and Patient-Reported Outcomes Measurement Information System [PROMIS]) were compared. A total of 3390 patients met inclusion criteria, with 855 receiving THA and 2535 receiving TKA. Among patients receiving THA, 440 (51.5%) saw a LC provider and 415 (48.5%) saw a LD provider. Those in the LC group had higher HOOS, JR scores at 1 year postoperatively (67.4 vs 49.3,
P
=.003) and were more likely to be discharged home (77.5% vs 69.9%,
P
=.013). Among patients receiving TKA, 1051 (41.5%) received LC care, whereas 1484 (58.5%) received LD care. There were no differences in outcome between the LC and LD TKA groups. Patients receiving THA with surgeons who spoke their language had improved patient-reported outcomes and were more commonly discharged home after surgery. Language concordance did not change outcomes in TKA. Optimizing language concordance for patients receiving TJA may improve postoperative outcomes. [

Published: June 2023

Postoperative deep infection is usually identified by microbial culture. However, frequent false-negative results have severely limited effective treatment. We report a rare case of intra-articular and paravertebral infection after total knee arthroplasty caused by
Mycoplasma hominis
and
Ureaplasma urealyticum
, with multiple negative microbial culture results. Eventually, the pathogens were identified using metagenomic high-throughput sequencing, and the patient was successfully treated with several “old” antibiotics. We analyze the clinical characteristics of this patient and systematically describe the application of high-throughput sequencing and antibiotics. [

Published: June 2023

Transiliac–transsacral screw fixation is widely used to stabilize unstable posterior pelvic ring injuries. Preoperative radiographic assessment of the safe osseous corridor is necessary because the safe space of sacrum is narrower for transiliac–transsacral screw placement than for traditional iliosacral screw placement. However, the radiographic assessment has rarely been studied in the Taiwanese population. We retrospectively analyzed 100 patients with pelvic computed tomography images and divided them into normal and dysmorphic pelvis groups. To determine the safe osseous space, we recorded cross-section area, cross-sectional diameter of the safe zone (CS-szD), and safe zone width on axial view (Ax-szW) in the S1 to S3 segments. The prevalence of dysmorphic pelvis was 48% among all patients. In the S1 segment, no differences were found in the cross-section area and CS-szD been the two groups. However, the Ax-szW was significantly smaller in the dysmorphic pelvis group. In the S2 segment, the cross-section area, CS-szD, and Ax-szW were all significantly larger in the dysmorphic pelvis group. In the S3 segment, the cross-section area and CS-szD of the normal pelvis group were both significantly smaller. No differences were found in the Ax-szW between the two groups. Based on our findings in a Taiwanese population, S1 was the most suitable segment for transiliac–transsacral screw fixation in a normal pelvis, whereas S2, followed by S3, was most suitable in a dysmorphic pelvis. This study offers surgeons information on identifying the optimal sacral segment for transiliac–transsacral screw placement for each pelvic morphology. [

Published: June 2023

The study utilizes an artificial neural network model for determining the fundamental period of Light-Frame Wooden Buildings, employing the Bat algorithm on a data set of 71 measured periods of wooden buildings. The number of stories, floor area, storey height, maximum length, and maximum width are selected as input parameters to estimate the fundamental period of light-frame wooden buildings. The accuracy and the competitiveness of the developed model were evaluated by comparing it with a similar particle swarm optimization (PSO)- ANN scheme, the formulas provided in the National Building Code of Canada, an equation obtained from the Eureqa software, and a non-linear regression (NLR) model. The results of the research show that the bat-ANN model exhibited the best overall performance with the lowest RMSE and MAE error values and the highest values of the Coefficient of determination, R2, in comparison to the other examined models. Therefore, the proposed Bat-ANN model can be considered as a reliable, robust, and accurate tool for predicting the fundamental period of wooden buildings.

Published: June 2023

The success of Machine Learning (ML) approaches as promising solutions has encouraged their widespread implementation across different fields. Owing to the high accident rate, the construction industry embraced ML in the risk assessment procedure. What if the machine produces knowledge of the relationship between the risk features and accident outcomes contained in the safety dataset? What if machines can explain an accident dataset without human intervention? Unsupervised ML techniques offer several advantages over supervised approaches, including their explainability to analyze and understand complex datasets. This chapter demonstrates the practical implementation of the unsupervised learning method, clustering, and dimensionality reduction to explain the similarities, differences, variances, and patterns that exist between the feature spaces of an occupational safety risk dataset. Principal component analysis (PCA) and K-means clustering with silhouette analysis were selected as two unsupervised ML approaches to demonstrate their implementation in enhancing data-centric decision-making during the construction risk assessment procedure.

Published: June 2023

Cognitive radio networks (CRNs) promise to meet device-to-device communication requirements for effective spectrum utilization and power control in a distributed environment for industrial applications. The architecture of the CRN must maintain a high data rate (throughput) at low power consumption, which requires both radio spectrum efficient and energy efficient system design. In order to attain these objectives, the architecture adopts a CRN model needs to operate in an interweave mode that allows spectrum sensing followed by opportunistic secondary user (SU) data transmission over the unused bandwidth of the primary user (PU) in an operating structure. It improves the usage of the radio spectrum intelligently. Cognitive radio works in tandem with artificial intelligence (AI) techniques to provide an intelligent allocation of resources for its users. This chapter aims to highlight the various AI techniques used in cognitive radio operations to enhance cognition capabilities in CRNs and present a review of the subject.
