Published: September 2022

A heterogeneous vehicular network (HetVNET) is a promising network architecture that combines multiple network technologies such as IEEE 802.11p, dedicated short-range communication (DSRC), and third/fourth generation cellular networks (3G/4G). In this network area, vehicle users can use wireless fidelity access points (Wi-Fi APs) to offload 4G long-term evolution (4G-LTE) networks. However, when using Wi-Fi APs, the vehicles must organize themselves and select an appropriate mobile gateway (MGW) to communicate to the cellular infrastructure. Researchers are facing the problem of selecting the best MGW vehicle to aggregate vehicle traffic and reduce LTE load in HetVNETs when the Wi-Fi APs are unavailable for offloading. The selection process utilizes extra network overhead and complexity due to the frequent formation of clusters in this highly dynamic environment. In this study, we proposed a non-cluster adaptive QoS-aware gateway selection (AQAGS) scheme that autonomously picks a limited number of vehicles to act as LTE gateways based on the LTE network’s load status and vehicular ad hoc network (VANET) application’s QoS requirements. The present AQAGS scheme focuses on highway scenarios. The proposed scheme was evaluated using simulation of Urban mobility (SUMO) and network simulator version 2 (NS2) simulators and benchmarked with the clustered and non-clustered schemes. A comparison was made based on the end-to-end delay, throughput, control packet overhead (CPO), and packet delivery ratio (PDR) performance metrics over Voice over Internet Protocol (VoIP) and File Transfer Protocol (FTP) applications. Using VoIP, the AQAGS scheme achieved a 26.7% higher PDR compared with the other schemes.
Optimal Capacity Decision-Making of Omnichannel Catering Merchants Considering the Service Environment Based on Queuing Theory
Authors: Zhan Wentao , Jiang Minghui , Wang Xueping
Published: September 2022

Many catering merchants are currently adopting omnichannel sales methods. At a restaurant, customers can place their orders, and while waiting for the food to be completed, they can enjoy the restaurant’s service environment. Online customers, by placing orders on various apps, can skip the queue, increasing their utility by reducing the opportunity cost, but they cannot enjoy the restaurant’s service environment. For merchants, it is important to adequately address how to choose the optimal capacity to provide services to customers in different channels and obtain optimal profits based on the service environment. In this paper, we establish a stylized theoretical model to study the impact of the service environment on customers’ shopping behavior online and offline, and we study how merchants can formulate the optimal capacity. Our main results are as follows: First, improving the service environment was conducive to reducing the merchants’ safety capacity and could help them obtain higher profits. In short-term omnichannel operations, merchants obtained higher profits than in traditional offline single-channel operations. Improving the service environment increased profits, but the profit difference between short-term omnichannel and offline single-channel operations gradually decreased. Finally, in long-term operations, the process of online customers transferring to offline channels based on a high-quality service environment might be detrimental to merchants’ profits.

Authors: Xu Cong , Wang Yu-Min
Published: September 2022

The rise of internet platforms meets people’s needs for a better life. However, the platforms also pose the risk of ecological monopolies. Using the methodology of economic analysis of law, with the help of ANT theory, the laws governing the operation of the platform ecosystem are discovered, and the paper analyzes the life cycle of digital platform development and figures out that the regulatory strategy for platforms should be adjusted to follow its life cycle and adopt more intuitive evaluation criteria for assessing market power. Meanwhile, the regulatory strategy for plat-forms could fully guarantee the active participation of multiple subjects, such as operators and consumers, in the platform’s governance. With the continuous advancement of data and algorithm technology, new content service providers will continue to emerge, and a new industry is developing. Besides the dynamic track analysis of platforms’ life cycles, another static research outcome is also given in this research. To ensure that the algorithmic technologies developed by the platform truly contribute to economic and social development and the well-being of people, the right to interpret algorithms and the establishment of scenario-based regulation of algorithms should be established.

Published: September 2022

The rapid increase in the proportion of the elderly population in China has increased the demand for aged services. It is a huge challenge for the Chinese government to establish the aged service system to meet such a large demand in a short time. In its 14th Five-Year Development plan, to promote a more rational allocation of health services, the Chinese government plans to build a health service system for the elderly. Based on the aged service resource allocation model established in the previous research, this paper proposes optimization measures and improves the model. The second-order matrix sensitivity analysis is performed on 30 parameters in the improved model, and the influence law of parameters on the whole system under a different amplitude of variation is explored. The results show that the disability rate of the elderly population, the service capacity of aged service institutions, per capita disposable income, and other factors have a great impact on the balance between the supply and demand of aged service resources. Therefore, when formulating policies related to the allocation of aged service resources, we can focus on improving the health level of the elderly, increasing the investment of social funds in aged service, and improving people’s consumption levels, so as to further improve the aged service system.

Published: September 2022

The growth of the aeronautical sector leads to the growth of polymer composites application, creating new demand for components applications in complex dimensions and shapes. Regarding different methods of draping 2D fabric into a 3D format, the concern is to keep the fabric properties and characteristics, since fiber orientation is modified after draping. For that purpose, this study aims to evaluate the drapability capacity of 2D dry fibrous fabrics (plain, twill, satin, non-crimp-fabric 0/90, and ±45) into a complex geometry, i.e., spherical indent. The energy required to drape fabric is composed of fabric deformation mechanisms (shear and bending), which were used together with microscopic deformation analysis to determine the appropriate fabric architectures with the highest malleability. Both NCF fabrics presented high energy and roughness on the fabric surface due to the folding effect of stitching. On the other hand, plain and twill weave fabrics required lower energy to drape but demonstrated higher fiber misalignment and deformation. The satin warp/weft relation favored shear and bending mechanisms, presenting better uniformity in load distribution, symmetry on drape capability, lower deformation degree, and lower fiber misalignment. Despite the intermediate load and energy required for drape, ANOVA and optimization methods confirmed that satin fabric showed better malleability behavior for complex geometries applications.

(1) Background: The normal A1 segment of the anterior cerebral artery (ACA) has a supraoptic course. The proximal infraoptic course of an A1 segment leaving the internal carotid artery (ICA) near the origin of the ophthalmic artery is a rare possibility. This study aimed to determine the prevalence and detailed anatomy of infraoptic A1 segments. (2) Methods: We retrospectively studied 145 computed tomography angiograms from 92 male and 53 female cases, with ages varying from 61 to 78 y.o. (3) Results: In 21/145 cases, infraoptic or infrachiasmatic horizontal-medial courses of A1 segments that emerged distally from the ICA were found. Distal infraoptic A1 segments were bilateral in 16/145 cases and unilateral in 3/145 cases. Infrachiasmatic A1 segments were found bilaterally in 2/145 male cases. All the infraoptic/infrachiasmatic A1 segments left long ICAs with low bifurcations. In 7/34 sides with distal infraoptic or infrachiasmatic A1 segments, supracarotid courses were present. In one female, the right A1 segment had an anterior supraclinoid, supracarotid and infraoptic course. In two female cases with a bilateral distal infraoptic A1, the segment was almost contacting the respective posterior cerebral artery. (4) Conclusions: In cases with dolicho(ectatic) ICAs, the A1 segments could have infraoptic and supracarotid courses the neurosurgeons should be aware of.

Published: September 2022

In various genome-wide correlation studies, interleukin (IL)28B gene polymorphism has been strongly correlated with both the therapeutic and spontaneous mediated clearance of hepatitis C virus (HCV). Therefore, this study aimed to evaluate the genotype and allele frequency distributions of IL28B (rs12979860) in patients with chronic hepatitis C and assess the IL28B polymorphisms as predictors of sustained virological response to SOF-based therapy for HCV in Egyptian patients. This retrospective case-control study was conducted on 54 chronic HCV patients who completed treatment with SOF/DCV ± RBV for 12 weeks and responded to treatment with SVR12 (the responder group) as a control group, and 54 chronic HCV patients who completed treatment with SOF/DCV ± RBV for 12 weeks and did not respond to treatment and failed to achieve SVR12 (the non-responder group) as a case group. The CC genotype frequency of IL-28B (rs12979860) was greater in the responder group (51.9%). In contrast, the TT genotype frequency was higher in the non-responder group (48.1%) (p < 0.001), and the T allele significantly increased the risk of non-responses by 3.13 fold. Therefore IL-28B (rs12979860) SNP could be used as a genetic predictor of sustained virological response to SOF+DCV ± RBV-based HCV treatment in Egyptian patients.
Study of Asymptotic Velocity in the Bondi–Hoyle Accretion Flows in the Domain of Kerr and 4-D Einstein–Gauss–Bonnet Gravities
Authors: Donmez Orhan , Dogan Fatih , Sahin Tuba
Published: September 2022

Understanding the physical structures of the accreted matter very close to a black hole in quasars and active galactic nucleus (AGN) is an important milestone to constrain the activities occurring in their centers. In this paper, we numerically investigate the effects of the asymptotic velocities on the physical structures of the accretion disk around the Kerr and Einstein–Gauss–Bonnet (EGB) rapidly rotating black holes. The Bondi–Hoyle accretion is considered with a falling gas towards the black hole in an upstream region of the computational domain. Shock cones are naturally formed in the downstream part of the flow around both black holes. The structure of the cones and the amount of the accreted matter depend on asymptotic velocity V∞ (Mach number) and the types of the gravities (Kerr or EGB). Increasing the Mach number of the in-flowing matter in the supersonic region reduces the shock opening angle and the accretion rates, because of the gas rapidly falling towards the black hole. The EGB gravity leads to an increase in the shock opening angle of the shock cones while the mass-accretion rates dM/dt decrease in EGB gravity with a Gauss–Bonnet (GB) coupling constant α. It is also confirmed that accretion rates and drag forces are significantly altered in the EGB gravity. Our numerical simulation results could be used in identifying the accretion mechanism and physical properties of the accretion disk and black hole in the observed X-rays such as NGC 1313 X-1 and 1313 X-2 and MAXI J1803-298.

Authors: Stratta Giulia , Pannarale Francesco
Published: September 2022

In 2015, the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) and Advanced Virgo began observing the Universe in a revolutionary way. Gravitational waves from cosmic sources were detected for the first time, confirming their existence predicted almost one century before, and also directly revealing the existence of black holes in binary systems and characterizing their properties. In 2017, a new revolution was achieved with the first observation of a binary neutron star merger, GW170817, and its associated electromagnetic emission. The combination of the information from gravitational-wave and electromagnetic radiation produced a wealth of results, still growing, spectacularly demonstrating the power of the newly born field of gravitational-wave Multi Messenger Astrophysics. We discuss the discovery of GW170817 in the context of the achievements it brought to Gamma-Ray Burst astrophysics, and we also provide a few examples of advancements in fundamental physics and cosmology. The detection rates of binary neutron star mergers expected in the next decade for third generation gravitational-wave interferometers will open the new perspective of a statistical approach to the study of these multi-messenger sources.

The research method used is a descriptive qualitative method with data collection techniques through questionnaires filled out by 12 early childhood children consisting of four boys and eight girls. This research was conducted in 3 stages, namely (1) pre-test, (2) socialization through songs and props; (3) final test. The results showed there was a change in children's interest in eating nutritious foods, as well as a decrease in children's interest in eating foods that were categorized as less nutritious. This means, the media song and props are quite successfully used in early childhood. From each result of data analysis, it can be seen that the media song and props have a positive impact on increasing interest in eating nutritious food at an early age in Cigugurgirang, Parongpong, Indonesia. With this research, it is expected to increase children's interest in consuming nutritious food so their Nutritional Adequacy Rate (RDA) will be fulfilled.
A New Species of the GenusCrenubiotus (Tardigrada: Eutardigrada: Adorybiotidae) from Salt Spring Island, Strait of Georgia, British Columbia (Canada)
Authors: Vecchi Matteo , Choong Henry , Calhim Sara
Published: September 2022

Currently, the recently erected genus Crenubiotus (Adorybiotidae, Macrobiotoidea) includes only three species, all of which are characterised by dentate lunulae and cuticular tubercules organised in the band in the dorso-caudal part of the body. By means of integrative taxonomy,
we describe a fourth species of the genus: Crenubiotus salishani sp. nov., from Salt Spring Island in British Columbia, Canada. The new species has been found in the moss growing on rock and differs from the other species in the genus due to the presence of a median anterior mucrone
in the third band of the oral cavity armature (OCA) and by the presence of evident thickenings on the eggshell connecting the neighbouring processes. This finding highlights the importance of continuing to study tardigrade biodiversity, even in already explored areas, and how an integrative
approach is fundamental to achieving a reliable measure of biodiversity.

Published: September 2022

This article reviews literature data on the working conditions, labor organization, health and psycho-emotional status, performance, and age composition of teaching staff. Population ageing is a global trend, primarily associated with increased life expectancy and decreased fertility rates. The reviewed publications note a steady increase in the number of elderly people employed in educational institutions of various levels. According to hygienic assessments, the working conditions of teaching staff can be distinguished as potentially harmful. High working, mental, emotional, and voice loads were found to be the key factors affecting teachers’ health, performance, and professional longevity. The accelerating pace of life, growing volumes of circulating information, spreading digitalization and robotization, adoption of online educational technologies  – all these phenomena impose an additional psychological burden on teachers, elderly people in particular, becoming a source of distress and neuroticism. At the same time, the involvement of elderly people in intellectually stimulating professional activities and the respective adequate payment were shown to have a positive effect on the preservation of their cognitive functions and overall quality of life. These findings determine the relevance of investigating the occupational hygiene of elderly teaching staff in order to develop measures aimed at preserving their health, quality of life, and professional longevity.

Authors: Ruchkin M. P. , Markelova E. V. , Fedyashev G. A.
Published: September 2022

Aim. To evaluate the serum levels of S100b protein, brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF) in patients with type 2 diabetes mellitus, as well as to establish a correlation between the studied parameters and retinal neurodegeneration.

Methods. In total, 80 patients with confirmed type 2 diabetes (experimental group) and 30 healthy volunteers (control group) were included in the study. All patients were examined using an RTVue-100 optic coherence tomography scanner (Optovue, USA) and a MAIA microperimeter (CenterVue, Italy). The serum levels of S100b, BDNF, and NGF were determined by a sandwich-type solid-phase enzyme immunoassay using reagents produced by R&D Diagnostics Inc. (USA).

Results. The serum level of S100b protein was found to be significantly (p = 0.001) higher in the experimental group, comprising 56.86 (31,12–104,02) pg/ml, compared to that in the control group of 45.19 (37.27–51.79) pg/ml. Conversely, the brain-derived neurotrophic factor (BDNF) showed a significant (p = 0.02) decrease to the level of 27.38 (25.15–29.12) pg/ml in the experimental group compared to the level of 30.19 (27.38–32.14) pg/ml in the control group. The serum level of nerve growth factor (NGF) in the experimental group was found to be 7.53 (5.63–10.54) pg/ml, thereby exceeding significantly (p = 0.02) the level of 5.96 (4.77–8.13) pg/ml in the control group.

Conclusions. The results obtained indicate an imbalance in the serum levels of the studied neuroproteins in patients with type 2 diabetes mellitus and retinal neurodegeneration signs. The identified variations require further research in order to determine the feasibility of their use as additional criteria for predicting the development of retinal neurodegeneration in such patients.

Published: September 2022

Aim. To develop a therapeutic strategy for uveitis complicated with macular edema (ME) based on topical corticosteroids (CS), including sub-Tenon’s administration of CS with subsequent intravitreal injection an Ozurdex implant.

Methods. The examination of 32 patients with chronic recurrent uveitis complicated with ME revealed a correlation between uveitis and the presence of systemic diseases (ankylosing spondylitis, rheumatoid arthritis, etc.). The patients were divided into two groups depending on the selected treatment after completion of the sub-Tenon’s administration of dexamethasone: 1st group – 17 patients with Ozurdex intravitreal implants; 2nd group – 15 patients receiving only dexamethasone instillations. Ophthalmological examination was carried out using optical coherence tomography and microperimetry. The markers of eye inflammation included the total clinical inflammation index and C-reactive protein (CRP) levels in lacrimal fluid (LF). The patients were examined prior to treatment as well as 10 days, 1, 3, 6, and 12 months after the completion of CS therapy. The control comprised functionalmorphological and laboratory parameters of 10 healthy people.

Results. The main intragroup differences were observed one month after the onset of treatment. Patients in the 1st group demonstrated the disappearance of clinical symptoms of uveal inflammation, with the CRP level in LF returning to normal (5.3 ± 0.07 mg/ml) values and differing insignificantly from the control. In these patients, the largest increase in functional parameters compared to the baseline was recorded, with the best corrected visual acuity (BCVA) and eye illumination sensitivity growing by 0.59 and 5.8 dB, respectively. Patients in the 2nd group demonstrated the persistence of some clinical symptoms of uveal inflammation. In these patients, optimal functional and morphological results were achieved three months after the onset of treatment. These results were not only inferior to those obtained in the 1st group, but also proved unstable over longer follow-up periods (6–12 months).

Conclusions. The developed optimized approach of CS therapy for uveitis complicated with ME confirmed its high clinical efficacy: a 3-fold reduction in the duration of uveal inflammation symptoms, a 1.25-fold increase in the frequency of complete ME resorption with the restoration of normal retinal topography in the macula, as well as a 2.2- and 2.35-fold increase in BCVA and eye illumination sensitivity, respectively.

Toward speed-of-sound anisotropy quantification in muscle with pulse-echo ultrasound
Authors: Korta Martiartu Naiara , Simutė Saulė , Jaeger Michael , Frauenfelder Thomas , Rominger Marga B.
Published: September 2022

The velocity of ultrasound longitudinal waves (speed of sound) is emerging as a valuable biomarker for a wide range of diseases, including musculoskeletal disorders. Muscles are fiber-rich tissues that exhibit anisotropic behavior, meaning that velocities vary with the wave-propagation direction. Therefore, quantifying anisotropy is essential to improve velocity estimates while providing a new metric related to muscle composition and architecture. For the first time, this work presents a method to estimate speed-of-sound anisotropy in transversely isotropic tissues using pulse-echo ultrasound. We assume elliptical anisotropy and consider an experimental setup with a flat reflector parallel to the linear probe, with the muscle in between. This setup allows us to measure first-arrival reflection traveltimes using multistatic operation. Unknown muscle parameters are the orientation angle of the anisotropy symmetry axis and the velocities along and across this axis. We derive analytical expressions for the nonlinear relationship between traveltimes and anisotropy parameters, including reflector inclinations. These equations are exact for homogeneous media and are useful to estimate the effective average anisotropy in muscles. To analyze the structure of this forward problem, we formulate the inversion statistically using the Bayesian framework. We demonstrate that anisotropy parameters can be uniquely constrained by combining traveltimes from different reflector inclinations. Numerical results from wide-ranging acquisition and anisotropy properties show that uncertainties in velocity estimates are substantially lower than expected velocity differences in the muscle. Thus, our approach could provide meaningful muscle anisotropy estimates in future clinical applications.
On Certain Edge-Transitive Bicirculants of Twice Odd Order
Authors: Kovács István , Ruff János
Published: September 2022

A graph admitting an automorphism with two orbits of the same length is called a bicirculant. Recently, Jajcay et al. initiated the investigation of the edge-transitive bicirculants with the properties that one of the subgraphs induced by the latter orbits is a cycle and the valence is at least $6$ (Electron. J. Combin., 2019). We show that the complement of the Petersen graph is the only such graph whose order is twice an odd number.
Shellability of Polyhedral Joins of Simplicial Complexes and Its Application to Graph Theory
Authors: Okura Kengo
Published: September 2022

We investigate the shellability of the polyhedral join $\mathcal{Z}^*_M (K, L)$ of simplicial complexes $K, M$ and a subcomplex $L \subset K$. We give sufficient conditions and necessary conditions on $(K, L)$ for $\mathcal{Z}^*_M (K, L)$ being shellable. In particular, we show that for some pairs $(K, L)$, $\mathcal{Z}^*_M (K, L)$ becomes shellable regardless of whether $M$ is shellable or not. Polyhedral joins can be applied to graph theory as the independence complex of a certain generalized version of lexicographic products of graphs which we define in this paper. The graph obtained from two graphs $G, H$ by attaching one copy of $H$ to each vertex of $G$ is a special case of this generalized lexicographic product and we give a result on the shellability of the independence complex of this graph by applying the above results.

Adhesion to material surfaces is crucial for almost all organisms regarding subsequent biological responses. Mammalian cell attachment to a surrounding biological matrix is essential for maintaining their survival and function concerning tissue formation. Conversely, the adhesion and presence of microbes interferes with important multicellular processes of tissue development. Therefore, tailoring bioselective, biologically active, and multifunctional materials for biomedical applications is a modern focus of biomaterial research. Engineering biomaterials that stimulate and interact with cell receptors to support binding and subsequent physiological responses of multicellular systems attracted much interest in the last years. Further to this, the increasing threat of multidrug resistance of pathogens against antibiotics to human health urgently requires new material concepts for preventing microbial infestation and biofilm formation. Thus, materials exhibiting microbial repellence or antimicrobial behaviour to reduce inflammation, while selectively enhancing regeneration in host tissues are of utmost interest. In this context, protein-based materials are interesting candidates due to their natural origin, biological activity, and structural properties. Silk materials, in particular those made of spider silk proteins and their recombinant counterparts, are characterized by extraordinary properties including excellent biocompatibility, slow biodegradation, low immunogenicity, and non-toxicity, making them ideally suited for tissue engineering and biomedical applications. Furthermore, recombinant production technologies allow for application-specific modification to develop adjustable, bioactive materials. The present review focusses on biological processes and surface interactions involved in the bioselective adhesion of mammalian cells and repellence of microbes on protein-based material surfaces. In addition, it highlights the importance of materials made of recombinant spider silk proteins, focussing on the progress regarding bioselectivity.

Based on phylogenetic analyses of a multi-gene matrix of nuITS-LSUrDNA,RPB2andTUB2sequences and morphology, xylariaceous species with uni- to pauciperitheciate stromata and ascospores having a spirally coiling (helicoid) germ slit are revised and reclassified, including detailed descriptions and illustrations. The genusHelicogermslitais redefined and restricted to seven species with massive, erumpent, clypeus-like carbonaceous stromata, andRosellinia somalais combined inHelicogermslita. Within the coreXylariaceae, the poorly knownLeptomassaria simplexis shown to be closely related toAnthostoma insidiosum, for which the new genusOligo stomais established, andAnthostoma rhenanumis demonstrated to be synonymous withO. insidiosum. The new genusAlbicollum, characterised by immersed ascomata and a collar of white pseudostromatic tissues surrounding the ostioles, is established forAmphisphaeria canicollis,Anthostoma chionostomum,Sordaria(=Helicogermslita)fleischhakiiandAnthostoma vincensii.Anthostoma ostropoidesis synomymised withAlbicollum canicolle, andAl. berberidicola,Al. longisporumandAl. novomexicanumare described as new species.Rosellinia(=Helico-germslita)gaudefroyiis transferred to the new genusSpiririma.Anthostoma amoenumandEuepixylon udum, both with a poroid germ locus, are shown to be only distantly related, andAn. amoenumis reclassified within the asexual genusDigitodochium. Based on phylogeny, the genusEuepixylonis treated as a synonym ofNemania. A new species,Nemania ethancrensonii, which is closely related to the two formerly acceptedEuepixylonspecies (E. sphaeriostomum,E. udum) but strongly deviates from the morphological concept ofEuepixylonandNemania, is described from the eastern USA. The generaAnthostomelloides,Clypeosphaeria,Digitodochium,Emarcaea,Induratia,Linosporopsis,Magnostiolata,OccultithecaandSpiririmaare revealed to form a morphologically heterogeneous lineage in a basal position ofXylariaceae.Anthostoma vincensii,Quaternaria simplexandRosellinia gaudefroyiare lectotypified, andAmphisphaeria canicollis,Anthostoma amoenum,An. rhenanum,An. vincensii,Quaternaria simplex,Rosellinia gaudefroyiandValsa insidiosaare epitypified. Keys to uni- to pauciperitheciate xylariaceous genera with sigmoid to helicoid germ slits and to species ofAlbicollumare provided.
Classification of Weeds of Paddy Fields using Deep Learning

Weed management is one of the important tasks in agriculture. Weeds in rice fields are usually managed using three ways - chemical herbicides, mechanical weeders, and manual weeding. Manual weeding becomes a problem when there is a shortage of agricultural laborers. Mechanical weeders are not suitable for direct-seeded rice fields. Chemical herbicides are not advisable especially when farmers do not know about site-specific weed management. Site-specific weed management is using the right herbicide in the right amount. Therefore, this paper investigates computer vision-based deep learning techniques with transfer learning classifying three types of weeds in paddy fields, namely sedges, grasses, and broadleaved weeds so that the right herbicide is recommended to the farmers. This would reduce the broadcast application and the overuse of the herbicides, thereby limiting the negative impact of the chemical herbicides on the environment. This research work shows promising results with an accuracy around 90% and thus encourages the development of digital agriculture.

The Double Asteroid Redirection Test (DART) is the first planetary defense test mission. It will demonstrate the kinetic impactor technique by intentionally colliding the DART spacecraft with the near-Earth asteroid Dimorphos. The main DART spacecraft is accompanied by the Italian Space Agency Light Italian CubeSat for Imaging of Asteroids (LICIACube). Shape modeling efforts will estimate the volume of Dimorphos and constrain the nature of the impact site. The DART mission uses stereophotoclinometry (SPC) as its primary shape modeling technique. DART is essentially a worst-case scenario for any image-based shape modeling approach because images taken by the camera on board the DART spacecraft, called the Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO), possess little stereo and no lighting variation; they simply zoom in on the asteroid. LICIACube images add some stereo, but the images are substantially lower in resolution than the DRACO images. Despite the far-from-optimal imaging conditions, our tests indicate that we can identify the impact site to an accuracy and precision better than 10% the size of the spacecraft core, estimate the volume of Dimorphos to better than 25%, and measure tilts at the impact site over the scale of the spacecraft with an accuracy better than 7°. In short, we will know with excellent accuracy where the DART spacecraft hit, with reasonable knowledge of local tilt, and determine the volume well enough that uncertainties in the density of Dimorphos will be comparable to or dominate the uncertainty in the estimated mass. The tests reported here demonstrate that SPC is a robust technique for shape modeling, even with suboptimal images.

BACKGROUND: Children with acyanotic congenital heart disease (CHD) had a high risk of stunting. In addition to inadequate nutrition, chronic inflammatory process also plays an important role. An increase in serum c-reactive protein (CRP) suppresses insulin like growth factor 1 (IGF-1) production, causing disorder in child growth.

AIM: The objective f the study was to prove that higher CRP levels as a risk factor of stunting in children with acyanotic CHD aged 6–24 months old.

METHODS: This study is an observational analytic study with a case–control design, to assess higher CRP levels as a risk factor of stunting in children with acyanotic CHD aged 6–24 months old. This research was conducted at the Pediatric Cardiology Polyclinic, Sanglah Hospital from May to December 2021 with the consecutive sampling method. Data analysis was performed using the Chi-square test or Fisher’s absolute test. Multivariate analysis with binary logistic regression was performed on all variables. Significance level was p < 0.05.

RESULTS: This study involved 60 subjects, consisting of 30 subjects with stunting and 30 subjects with no stunting. Children with stunting had higher mean CRP levels, 2.4 (±3.7) and 1.2 (±0.6). CRP level ≥3 mg/dL (p = 0.031; aOR 22.89; 95% CI 1.32–395.39) was a risk factor of stunting in children with acyanotic CHD. Other risk factors that significant are male, living in rural areas, low birth weight, and under-nutrition.

CONCLUSION: Higher CRP levels as a risk factor of stunting in children with acyanotic CHD. Other significant risk factors include males, living in rural areas, low birth weight, and under-nutrition.
