The importance of automating pavement maintenance tasks for highway systems has garnered interest from both industry and academia. Despite significant research efforts and promising demonstrations being devoted to reaching a level of semi-automation featuring digital sensing and inspection, site maintenance work still requires manual processes using special vehicles and equipment, reflecting a clear gap to transition to fully autonomous maintenance. This paper reviews the current progress in pavement maintenance automation in terms of inspection and repair operations, followed by a discussion of three key technical challenges related to robotic sensing, control, and actuation. To address these challenges, we propose a conceptual solution we term Autonomous Maintenance Plant (AMP), mainly consisting of five modules for sensing, actuation, control, power supply, and mobility. This AMP concept is part of the “Digital Roads” project’s cyber-physical platform where a road digital twin (DT) is created based on its physical counterpart to enable real-time condition monitoring, sensory data processing, maintenance decision making, and repair operation execution. In this platform, the AMP conducts high-resolution survey and autonomous repair operations enabled (instructed) by the road DT. This process is unmanned and completely autonomous with an expectation to create a fully robotized highway pavement maintenance system.

Online food delivery applications (OFDAs) have seen a surge in popularity during the COVID-19 Pandemic, particularly among young adults. This study aimed to assess the use of OFDAs and the perception of food healthiness and safety among university students in the United Arab Emirates (UAE). A web-based cross-sectional study was conducted among university students in the UAE via snowball sampling (n = 1096). Sociodemographic characteristics, OFDAs usage, and perceptions toward food healthiness and safety were investigated. Chi-square analysis was used to determine the association between categorical variables and healthy food choices. Mann–Whitney U and Kruskal–Wallis H tests were used to determine differences between different groups and perception statements. Over half (52%) of the students were frequent users of OFDAs with fast food being the most popular choice (88.4%). Older participants, those living in the university dorms, and those with higher allowances used the OFDAs more frequently (P < 0.05). Price (78.0%) and food appearance (65.7%) had the highest impact on food selection. Most subjects (69.3%) reported looking for healthy food but were worried about affordability (43.1%) and taste (27.1%). Most participants (57.8%) agreed that OFDAs increased their appetite and food intake. Participants believed that having a hygiene rating system in OFDAs would give them the chance to make informed decisions (82.3%). Unhealthy food options were popular among university students. The study highlights the need to provide more affordable and appealing healthy food options and suggests that improved nutrition information and hygiene standards could help to promote healthy food choices among university students.

We investigate whether Palestinian Arabic (PA), as spoken by the local Palestinian refugee population in Beirut, is converging with Lebanese Arabic (LA), the majority variety. Using a sociolinguistic framework, we target three variables considered to be susceptible to convergent change. We find evidence of contact-induced change in PA in the variable raising of word-medial /a:/ to [e:], as well as in the attrition of socially marked exponents of verbal negation. By contrast, in the case of the third variable, the future temporal reference system, the evidence for convergence is less compelling on account of key differences between the contact varieties, including the vertiginous rise of the proclitic future marker ħa- in PA. We implicate the respective social salience of the targeted variables in their differential susceptibility to convergence. Our results afford new insights into dialect contact and elucidate under-studied patterns of grammatical variation and change in Levantine Arabic.

Background: Stereotactic laser amygdalohippocampotomy (SLAH) has recently been shown to be comparable to traditional temporal lobectomy procedures. The ideal extent and volume of laser ablations remains an area of investigation Methods: 65 patients treated with SLAH for MTS were considered in this retrospective study. Manual segmentations of ablations were created using post-procedure T1-MRI scans. Ablations were assessed in relation to whether they crossed the coronal plane of the superior lateral mesencephalic sulcus (LMS), the extent to which ablation crossed this landmark, and extent of ablation of the uncus. Analysis of was done with binary categorization of 12-month Engel classification score. Results: Distance of ablation posterior to the coronal plane of the LMS was not associated with better surgical outcome (Engel class 1: 6.32 ± 4.16 mm; Engel class 2-4: 7.93 ± 3.75mm; (p = 0.099)). Ratio of ablations extending posterior to the LMS was 0.82 (SD = .39) in Engel 1 patients, and 0.90 (SD = 0.3) in Engel 2-4 patients; (p = 0.370). Volume of ablation showed little correlation with outcome (Engel class 1: 6064 ± 2128 mm3; Engel class 2-4: 5828 ± 3031 mm3; (p=0.239)). Ablation of the uncus showed a strong association with better surgical outcome (Engel class 1: 0.71(SD = 0.31); Engel 2-4: 0.37 (SD = 0.36); p <0.001). Conclusions: Contrary to current practice, extension of ablation posterior to the LMS did not demonstrate improved outcome.

In this paper, a hybrid approach organized in four phases is proposed to solve the multi-objective trajectory planning problem for industrial robots. In the first phase, a transcription of the original problem into a standard multi-objective parametric optimization problem is achieved by adopting an adequate parametrization scheme for the continuous robot configuration variables. Then, in the second phase, a global search is performed using a population-based search metaheuristic in order to build a first approximation of the Pareto front (PF). In the third phase, a local search is applied in the neighborhood of each solution of the PF approximation using a deterministic algorithm in order to generate new solutions. Finally, in the fourth phase, results of the global and local searches are gathered and postprocessed using a multi-objective direct search method to enhance the quality of compromise solutions and to converge toward the true optimal PF. By combining different optimization techniques, we intend not only to improve the overall search mechanism of the optimization strategy but also the resulting hybrid algorithm should keep the robustness of the population-based algorithm while enjoying the theoretical properties of convergence of the deterministic component. Also, the proposed approach is modular and flexible, and it can be implemented in different ways according to the applied techniques in the different phases. In this paper, we illustrate the efficiency of the hybrid framework by considering different techniques available in various numerical optimization libraries which are combined judiciously and tested on various case studies.

During a 1-year study, Trichuris adults were obtained after necropsy of Arabian camels (Camelus dromedarius) from a slaughterhouse in Kuwait. Morphological and molecular identification was performed to confirm the identity of the Trichuris specimens obtained from C. dromedarius. Fifteen male Trichuris specimens were selected, and molecular identification was performed using mitochondrial cytochrome c oxidase subunit I, 12S ribosomal RNA, 16S ribosomal RNA genes and the nuclear internal transcribed spacer 2 (ITS2) region. Through phylogenetic analysis, 2 distinct groups were obtained using the mitochondrial genes, where group 1 showed a close relationship to Trichuris globulosa while group 2 showed a close relationship to Trichuris ovis, providing molecular evidence of a possible T. globulosa species complex. Additionally, the nuclear ITS2 region did not provide enough resolution to distinguish between the 2 groups of Trichuris specimens. Observation of morphological characters revealed variations in the shape of the male spicule sheath, where specimens present either a globular posteriorly truncated swelling or the absence of posteriorly truncated swelling. Moreover, the variations in male spicule sheath does not corroborate with the results of molecular data, suggesting the limited use of this character for identification of T. globulosa. In conclusion, molecular analysis suggests a possible species complex in T. globulosa, with the mitochondrial genetic markers successfully differentiating between the 2 groups. The limited use of the male spicule sheath as a diagnostic character for identification of T. globulosa is suggested.

Trichinellosis is a global food-borne disease caused by viviparous parasitic nematodes of the genus Trichinella. Due to the lack of effective, safe therapy and the documented adverse effects of traditional therapy, this study aimed to evaluate the therapeutic effect of acetazolamide-loaded silver nanoparticles (AgNPs) on murine trichinellosis. Fifty male Swiss albino mice were divided into five groups of ten mice each: Group I, normal control group; Group II, infected with T. spiralis and not treated; Group III, infected and given AgNPs; Group IV, infected and treated with acetazolamide; and Group V, infected and treated with acetazolamide-loaded AgNPs. Mice were infected orally with 250 larvae. The efficacy was assessed by counting T. spiralis adults and larvae, measuring serum total antioxidant capacity, and observing the histopathological and ultrastructural alterations. Acetazolamide-loaded AgNPs treatment exhibited the highest percentage of reduction (84.72% and 80.74%) for the intestinal adults and the muscular larvae of T. spiralis-infected animals, respectively. Furthermore, during the intestinal and muscular phases, the serum of the same group had the best free-radical scavenging capacity (antioxidant capacity), which reduced tissue damage induced by oxidative stress. Histopathologically, the normal intestinal and muscular architecture was restored in the group treated with acetazolamide-loaded AgNPs, in addition to the reduced inflammatory infiltrate that alleviated inflammation compared to infected animals. Our results confirmed the marked destruction of the ultrastructural features of T. spiralis adults and larvae. Acetazolamide-loaded AgNPs are a promising therapy against T. spiralis infection.

Numerous studies have been conducted globally to assess the compliance level of newspapers with the World Health Organization’s media guidelines for responsible suicide reporting. To identify and review such studies conducted in Muslim-majority countries between 2014 and 2022, we searched PubMed and Google Scholar databases. We identified 12 eligible studies from Pakistan (n = 4), Bangladesh (n = 2), Malaysia (n = 1), Indonesia (n = 1), Iraq (n = 1), Iran (n = 1), Nigeria (n = 1), and Egypt (n = 1). These studies indicated an overall lack of adherence to the guidelines. However, the level of nonadherence was particularly high in Pakistan. Effective suicide prevention programs may help in promoting responsible reporting of suicide.

Pakistan has suffered heavy losses due to the torrential monsoon rains of 2022. With obliterated infrastructure and rising disease burden, the nation is still reeling from the dismal aftermath. It is critical to understand that such catastrophes are not a 1-time calamity but are likely to become more frequent with growing severity of the climate crisis. These losses point to a more systemic problem that is a lack of preparedness, and without sustainable long-term measures in place, the nation remains just as vulnerable to the next ‘unpredictable’ weather contingency. Prior planning and effective allocation of resources can help develop a proactive response to future disasters of this magnitude.

Background: Studies of deep brain stimulation (DBS) require accurate electrode localization and image registration. We used anatomical fiducials to investigate localization and registration errors in patients who underwent subthalamic nucleus (STN) DBS for Parkinson’s disease (PD). Methods: We conducted a retrospective analysis of patients who underwent bilateral STN DBS for PD. Pre and post operative MRI scans were non-linearly normalized to a standard template (MNI152NLin2009bAsym). Four raters localized DBS electrodes (Lead-DBS), the anterior commissure (AC) and posterior commissure (PC). Errors between rater localizations were calculated (fiducial localization error; FLE). We transformed AC and PC coordinates from template to patient space to calculate the fiducial registration error (FRE)Results: Ninety-nine patients were analyzed, with a median FLE of 0.76mm, 0.74mm, 0.71mm and 0.66mm for the right electrode, left electrode, AC and PC respectively (no significant difference, Wilcoxon sign rank). The median FRE was 1.59mm for AC and 1.21mm for PC, significantly higher than FLE at those coordinates (Wilcoxon sign rank, p<0.001). Conclusions: Raters can accurately localize DBS electrodes, AC and PC from clinical images with sub-millimetric accuracy. Higher FREs at AC and PC suggested registration errors may contribute more than localization errors to electrode uncertainty in a common space.

Modern nation–states typically strive to define the cultural memory of a society by promoting certain historical narratives through mass media, museums, monuments, education, national holidays, and the like. Although huge differences exist between states in the realm of cultural policies, they usually entail the marginalization of certain groups or collective memories and often mark their exclusion from the imagined national collective. But even if publicly suppressed or silenced, the collective memory of marginal groups continues to thrive in the private sphere or in protected social niches. The dichotomy between public and private memory is not rigid, as state hegemony in the sphere of cultural memory fluctuates and is rarely complete.

Due to the increasing demand for antibiotic-free livestock products from the consumer side and the ban on the use of antibiotic growth promoters, the poultry feed industry is increasingly interested in developing more alternatives to cope with this problem. Organic acids (butyric acid) have many beneficial effects on poultry health, performance, and egg quality when used in their diet, thus they can be considered for the replacement of antibiotics in livestock production systems. Butyric acid is most efficacious against pathogenic bacteria such as Salmonella spp. and Escherichia coli, and stimulates the population of beneficial gut bacteria. It is a primary energy source for colonocytes and augments the differentiation and maturation of the intestinal cells. Collectively, butyric acid should be considered as an alternative to antibiotic growth promoters, because it reduces pathogenic bacteria and their toxins, enhancing gut health thereby increasing nutrient digestibility, thus leading to improved growth performance and immunity among birds. The possible pathways and mechanisms through which butyric acid enhances gut health and production performance are discussed in this review. Detailed information about the use of butyric acid in poultry and its possible benefits under different conditions are also provided, and the impacts of butyric acid on egg quality and osteoporosis are noted.
