    Abstract In this paper, multipath ultrasonic flowmeter using phased array transducer is introduced to measure the flowrate. In the proposed flowmeter, the path velocities are achieved by dynamic beam steering via phased array sensor then numerical integration is used to calculate the flowrate. Turbulent flow profile through a straight pipe, flow field downstream of single bend, and double bend are studied in this paper. For each case, the influence of the number of paths, beam angle, and installation angle on the performance of the proposed flowmeter is discussed. Because of symmetric velocity profile for turbulent flow through the straight pipe, relative errors are not dependent on the installation angle and its minimum value is obtained 0.03 % under [±56.6°, 0] path arrangement. Relative errors after single and double bend depend on the installation angle due to the asymmetric flow field. In 3-path configuration, for velocity profile after single bend and double bend, the minimum error range is 1.35 % and 2.38 % under [±55

    Abstract Abstract Today, surface-piercing propellers have been recognized as a suitable choice for higher speeds. Yet, the development of design algorithms for such has been challenged by insufficient knowledge about the parameters affecting their performance. For this reason, developing experimental data and studying the influence of various parameters on their performance is crucial. Aiming to develop experimental knowledge of these propellers, this study investigates the impact of position parameters and Froude Number on model test results of a custom-designed propeller. Moreover, ventilation wake development at different Froude numbers was studied. The experimental results pointed to the favorable impact of increased immersion ratio on propeller's thrust, a positive impact of increasing the inclination angle by 6° on higher thrust and efficiency in the advance direction, and a slight increase of thrust with higher yaw angles up to 10°. The propeller's lateral forces were also extracted in different positions and operational conditions to identify the propeller's behavior and design the required shaft and supports. Finally, regression equations for projecting hydrodynamic coefficients used at the design phase were compared and verified by the experimental results. The results pointed to the insufficient precision of this model for estimating the hydrodynamic coefficients affecting the propeller.

    Abstract Named Entity Recognition is a challenging task, specially for low resource languages, such as Persian, due to the lack of massive gold data. As developing manually-annotated datasets is time consuming and expensive, we use a multitask learning (MTL) framework to exploit different datasets to enrich the extracted features and improve the accuracy of recognizing named entities in Persian news articles. Highly motivated auxiliary tasks are chosen to be included in a deep learning based structure. Additionally, we investigate the effect of chosen datasets on performance of the model. Our best model significantly outperformed the state of the art model by , according to F1 score in the phrase level.

    Abstract Objective: To detect common chromosomal aneuploidy variations in embryos from couples undergoing assisted reproductive technology and preimplantation genetic screening and their possible associations with embryo quality. Methods: In this study, 359 embryos from 62 couples were screened for chromosomes 13, 21, 18, X, and Y by fluorescence insitu hybridization. For biopsy of blastomere, a laser was used to remove a significantly smaller portion of the zona pellucida. One blastomere was gently biopsied by an aspiration pipette through the hole. After biopsy, the embryo was immediately returned to the embryo scope until transfer. Embryo integrity and blastocyst formation were assessed on day 5. Results: Totally, 282 embryos from 62 couples were evaluated. The chromosomes were normal in 199 (70.57%) embryos and abnormal in 83 (29.43%) embryos. There was no significant association between the quality of embryos and numerical chromosomal abnormality (P=0.67). Conclusions: Embryo quality is not significantly correlated with its genetic status. Hence, the quality of embryos determined by morphological parameters is not an appropriate method for choosing embryos without these abnormalities.

    Abstract Abstract As a common belief, most viruses can egress from the host cells as single particles and transmit to uninfected cells. Emerging data have revealed en bloc viral transmission as lipid bilayer-cloaked particles via extracellular vesicles especially exosomes (Exo). The supporting membrane can be originated from multivesicular bodies during intra-luminal vesicle formation and autophagic response. Exo are nano-sized particles, ranging from 40–200 nm, with the ability to harbor several types of signaling molecules from donor to acceptor cells in a paracrine manner, resulting in the modulation of specific signaling reactions in target cells. The phenomenon of Exo biogenesis consists of multiple and complex biological steps with the participation of diverse constituents and molecular pathways. Due to similarities between Exo biogenesis and virus replication and the existence of shared pathways, it is thought that viruses can hijack the Exo biogenesis machinery to spread and evade immune cells. To this end, Exo can transmit complete virions (as single units or aggregates), separate viral components, and naked genetic materials. The current review article aims to scrutinize challenges and opportunities related to the exosomal delivery of viruses in terms of viral infections and public health. Video Abstract

    Title translation Fylkesforskjeller i utredning og behandling av vitamin B12-mangel.
    Abstract Background: Severe vitamin B12 (cobalamin) deficiency is rare, but international reports show that up to 26 % of the general population may have subclinical vitamin B12 deficiency. The prevalence of vitamin B12 deficiency has not been investigated in Norway. Since 2017, treatment with vitamin B12 tablets has represented an alternative to traditional treatment with intramuscular injections in Norway. When we studied the transition from injection to tablet treatment, we discovered an unexpected difference in the counties' use of vitamin B12 supplements, which we wished to investigate in more detail.
    Material and method: Data on the dispensing of vitamin B12 supplements from pharmacies in 2020, broken down by the patients' county of residence, were retrieved from the Norwegian Prescription Database. The Norwegian Health Economics Administration (Helfo) provided figures on the number of reimbursed vitamin B12-related laboratory tests in 2020, classified by patients' municipality of residence.
    Results: In 2020, the sale of vitamin B12 supplements on prescription in Norway amounted to 12 defined daily doses (DDD) per inhabitant and varied from 7 to 15 between the counties. The number of laboratory analyses that were performed varied by county from 26 to 46 per 100 inhabitants for total vitamin B12, and from 21 to 37 for folate. The number of analyses varied correspondingly from 1 to 12 per 100 inhabitants for homocysteine, from 1 to 13 for methylmalonic acid and from 0.01 to 8.13 for active vitamin B12.
    Interpretation: Our study showed large intercounty differences in the consumption of vitamin B12 supplements. These differences may have a number of explanations. Variations in the number of vitamin B12-related laboratory analyses requisitioned may indicate that doctors' assessment and diagnosis of vitamin B12 deficiency could be a contributory factor.

    Abstract We have previously shown that the use of hypnotic drugs increased among young Scandinavians during 2012-2018. This study aimed to explore psychiatric and somatic morbidity among adolescent hypnotic drug users in a cohort study of 13-17-year-old individuals during 2008-2018 in Norway. Data sources were (i) prescription data from the Norwegian Prescription Database linked to specialist health care diagnoses from the Norwegian Patient Registry and (ii) sleep disorder diagnoses from the Primary Health Care Database. Hypnotic drugs were defined as the sedative antihistamine alimemazine and the ATC group "Hypnotics and Sedatives" (N05C), excluding midazolam. In 2017, 2519 girls (16.5/1000) and 1718 boys (10.7/1000) were incident (new) users of hypnotic drugs. Most of these new users (82% of girls, 77% of boys) were referred to secondary health care, where the most frequent diagnoses were mental and behavioral disorders (51.8% of girls, 46.2% of boys), while only 3.2% received a specific sleep disorder diagnosis. The most common mental and behavioral disorders were "Neurotic stress-related disorders" among girls (27.4%) and "Behavioral and emotional disorders" among boys (23.6%). In conclusion, the trend of increasing hypnotic drug use among adolescents reflects the initiation of hypnotic drugs in a subgroup of the population with a higher disease burden, mainly due to psychiatric disorders, than the general population.

    Abstract Abstract: Introduction: Today, commercial complexes are among the most important shopping centers in cities that account for one of the most important urban development infrastructures. Evaluation and management of fire is essential to prevent accidents and disasters such as fires. Due to the increased population density and slow access to safe and secure outdoor space during the disaster, human casualties and financial losses have increased. The aim of this study was to make strategic decisions in fire risk management in Aftab Gorgan commercial complex using artificial intelligence model. Method: In this study, all technical documentation, including technical-physical and urban properties as well as notification and extinguishing system of the commercial complex under study were investigated. Later, the important and influential components of the design were identified, paired, weighted, and compared using Delphi questionnaires. In the next stage, the SWOT matrix was applied and quadratic strategies were designed and modeled after designing a hierarchical tree to model and prioritize the strategies. Results: According to the outputs of the performed modeling using Matlab and Neuro-Solution 5 software, we found that in weighting and ranking of the eight designed strategies, only one strategy was ranked (and has equal priority) in both models and other scenarios were different. Therefore, integrating strategies for fire risk management was considered essential. Conclusion: The findings showed that the strategy of adopting the systematic and strategic-operational management approach of fire risk in Gorgan Aftab 3 Complex design were the most ideal possible strategies. This was due to the special attention paid to optimization of physical spaces and fire alarm systems as well as implementation of business classification and continuous excellence system of HSE-MS and crisis management.

    Abstract Abstract Background Oxidative stress has an undeniable role in the impairment of sperm function and idiopathic male infertility. On the other hand, the local antioxidant system particularly glutathione peroxidase 3 (GPX3) as an extracellular enzyme protects male fertility from oxidative damages. Therefore, in the current study, we evaluated the association between two functional polymorphisms of the GPX3 gene with its levels in seminal fluid and subsequently with the risk of male infertility. Result We recruited 100 fertile and 100 infertile men for the study. Our results showed that the concentration of GPX3 was higher in the fertile group than infertile patients (p= <0.01), and there were positive correlations between GPX3 concentration in seminal fluid with sperm motility and morphology. The frequency of rs8177404 and rs3828599 genotypes and alleles was significantly different between the groups and we found that having the rs8177404 polymorphism (TC and CC genotypes) could increase the risk of idiopathic infertility more than 2-fold. On the other hand, the GG genotype (rs3828599) showed a protective effect against infertility. Our results demonstrated that men carrying CC genotype of rs8177404 polymorphism had significantly lower progressively motile sperm and higher immotile sperm compared with subjects carrying TT and TC genotypes. In the rs3828599 polymorphism, the GG carriers had significantly higher progressively motile and lower immotile sperm than AA carriers. Furthermore, men with genotypes of CC (rs8177404) and GG (rs3828599) had significantly lower and higher levels of GPX3 in the seminal fluid, respectively. Conclusion In conclusion, our results showed associations between sperm parameters with GPX3 levels and the gene polymorphisms. It seems rs8177404 and rs3828599 polymorphisms can affect GPX3 levels in seminal fluid and subsequently sperm parameters.

    Abstract Abstract Vesicular system of mammalian cells is composed of two intracellular and extracellular vesicles systems, which contributes to the intra/intercellular communication and cellular homeostasis. These systems mediate transferring of biological molecules like proteins, nucleic acids, and lipids inside the cytoplasm, and between the cells. By the present study, authors describe molecular crosslink between exosome biogenesis and autophagy and take a certain focus on the autophagic cargos of exosomes and signaling pathways involved in exosome-induced autophagy in target cells and vice versa. Autophagy the generation of double-phospholipid vesicles, is a process that engulfs damaged proteins and organelles, share molecular similarity and function synergy with exosomes biogenesis for degradation or exocytosis of certain cargo. Exosomes, the smallest subtype of extracellular vesicles, originating from the membrane of the multivesicular body located inside cells demonstrate key roles in the intracellular and intercellular communication. Growing evidence demonstrates the interaction between exosome biogenesis and autophagy both at intertwined molecular pathways and crossbred vesicles known as amphisomes. Crosstalk between exosome biogenesis and autophagy contributes to maintain cellular homeostasis under external and internal stresses. Moreover, these processes can modulate each other via different signaling pathways. Exosomes contain autophagic cargos that induce autophagy via the cascade of molecular events in target cells, which called here exosome-induced autophagy. Taken together, crosstalk between exosome biogenesis and autophagy plays pivotal roles in cell homeostasis. Shedding light on the interaction between endomembrane systems may promote our knowledge about the relation between exosome and autophagy pathways in lysosome-related disorders against treatments; proposing a theoretical approach for therapy.
