Dirty fireballs are a hypothesized class of relativistic massive-star explosions with an initial Lorentz factor Γinit below the Γinit ∼ 100 required to produce a long-duration gamma-ray burst (LGRB), but which could still produce optical emission resembling LGRB afterglows. Here we present the results of a search for on-axis optical afterglows using the Zwicky Transient Facility (ZTF). Our search yielded seven optical transients that resemble on-axis LGRB afterglows in terms of their red colors (g − r > 0 mag), faint host galaxies (r > 23 mag), rapid fading (dr/dt > 1 mag day−1), and in some cases X-ray and radio emission. Spectroscopy of the transient emission within a few days of discovery established cosmological distances (redshift z = 0.876 to 2.9) for six of the seven events, tripling the number of afterglows with redshift measurements discovered by optical surveys without a γ-ray trigger. A likely associated LGRB (GRB 200524A, GRB 210204A, GRB 210212B, and GRB 210610B) was identified for four events (ZTF 20abbiixp/AT 2020kym, ZTF 21aagwbjr/AT 2021buv, ZTF 21aakruew/AT 2021cwd, and ZTF 21abfmpwn/AT 2021qbd) post facto, while three (ZTF 20aajnksq/AT 2020blt, ZTF 21aaeyldq/AT 2021any, and ZTF 21aayokph/AT 2021lfa) had no detected LGRB counterpart. The simplest explanation for the three “orphan” events is that they were regular LGRBs missed by high-energy satellites owing to detector sensitivity and duty cycle, although it is possible that they were intrinsically subluminous in γ-rays or viewed slightly off-axis. We rule out a scenario in which dirty fireballs have a similar energy per solid angle to LGRBs and are an order of magnitude more common. In addition, we set the first direct constraint on the ratio of the opening angles of the material producing γ-rays and the material producing early optical afterglow emission, finding that they must be comparable.

We present the photometry of 16 91T/99aa-like Type Ia Supernovae (SNe Ia) observed by the Las Cumbres Observatory. We also use an additional set of 21 91T/99aa-like SNe Ia and 87 normal SNe Ia from the literature for an analysis of the standardizability of the luminosity of 91T/99aa-like SNe. We find that 91T/99aa-like SNe are 0.2 mag brighter than normal SNe Ia, even when fully corrected by the light-curve shapes and colors. The weighted rms of the 91T/99aa-like SNe (with z
CMB > 0.01) Hubble residuals is 0.25 ± 0.03 mag, suggesting that 91T/99aa-like SNe are also excellent relative distance indicators to ±12%. We compare the Hubble residuals with the pseudo-equivalent width (pEW) of Si ii
λλ6355 around the date of maximum brightness. We find that there is a broken linear correlation between those two measurements for our sample including both 91T/99aa-like and normal SNe Ia. As the

pEW
max

(Si ii
λλ6355) increases, the Hubble residual increases when

pEW
max

(Si ii
λλ6355) < 55.6 Å. However, the Hubble residual stays constant beyond this. Given that 91T/99aa-like SNe possess shallower Si ii lines than normal SNe Ia, the linear correlation at

pEW
max

(Si ii
λλ6355) < 55.6 Å can account for the overall discrepancy of Hubble residuals derived from the two subgroups. Such a systematic effect needs to be taken into account when using SNe Ia to measure luminosity distances.
Lepto-hadronic Jet-disk Model for the Multiwavelength SED of M87
Authors: Boughelilba Margot , Reimer Anita , Merten Lukas
Published: October 2022

The low-luminosity active galactic nuclei M87, archetype of Fanaroff–Riley I radio galaxies, was observed in a historically quiet state in 2017. While one-zone leptonic jet models alone cannot explain the core radio-to-gamma-ray spectrum, we explore a hybrid jet-disk scenario. In this work, we model the overall spectral energy distribution of M87's core with a dominating one-zone lepto-hadronic jet component, coupled with the contribution from the accretion flow. We find close-to-equipartition parameter sets for which the jet component fits the radio-to-optical data as well as the gamma-ray band, while the accretion flow mainly contributes to the X-ray band. The effects of gamma-ray absorption by the extragalactic background light during the propagation toward Earth are probed and are found to be negligible for this model. The neutrino flux produced by such scenarios is also calculated, but remains below the current instruments’ sensitivity.
A New Approach to Kinetic Energy Flux at the Different Frequencies above the IRIS Bright Points*
Authors: Sadeghi Rayhane , Tavabi Ehsan
Published: October 2022

Various bright structures abound in the chromosphere playing an essential role in the dynamics and evolution therein. Tentatively identifying the wave characteristics in the outer solar atmosphere helps to understand this layer better. One of the most significant aspects of these characteristics is the wave phase speed (PS), which is a dominant contribution to solar coronal heating and energy distribution in the Sun’s atmosphere layers. To obtain energy flux (EF), it is necessary to calculate the filling factor (FF) and the PS. In this study, the FF was determined by tracking the size and intensity of the IRIS bright points (BPs). To estimate an accurate PS and EF, it is necessary to know the chromosphere and transition region (TR) thickness and the phase difference between the two desired levels. Chromosphere and TR thickness cannot be measured directly on the disk; this study is performed using spectral data and calibrated based on Doppler velocities. As a result, the PSs in active regions (ARs) and coronal holes (CHs), as well as the IRIS BPs, have been calculated using the cross-power wavelet transform of Doppler velocities. Consequently, about the CH, the PS mean values are from 40 to 180 km s−1 at the network and from 30 to 140 km s−1 at the internetwork; and about the AR, they are from 80 to 540 km s−1 at the network and 70 to 220 km s−1 at the internetwork. Finally, the EF for the IRIS BPs has been calculated in three different frequencies. The results indicate that the network BPs have an influential role in heating the higher layers, while in the internetwork BPs most of the energy returns to the lower layers.
The Origin and Distance of the High-velocity Cloud MI
Authors: Schmelz J. T. , Verschuur G. L.
Published: October 2022

The high-velocity, neutral hydrogen feature known as MI may be the result of a supernova that took place about 100,000 yr ago at a distance of 163 pc. Low-velocity H i data show a clear cavity, a structure indicative of regions evacuated by old exploding stars, centered on the spatial coordinates of MI, (l, b) = (165°, 65.°5). The cavity is also visible in 100 μm dust data from IRAS. The invisible companion of the yellow giant star, 56 Ursae Majoris, may be the remains of the supernova that evacuated the cavity and blasted MI itself outward at 120 km s−1. The mass and energy of MI are easily in line with what is expected from a supernova. The diffuse X-rays seen by ROSAT provide evidence of a hot cavity, and the enhanced X-rays may result from the subsequent bow shock.

As Representações das mulheres guineenses na obra "Eterna Paixão" de Abdulai Sila
Authors: Cruz Luciene Rocha dos Santos
Published: October 2022

O presente artigo tem o objetivo de detectar e analisar as representações das mulheres guineenses, observadas na obra “Eterna Paixão” (2002), de Abdulai Sila, tentando identificar se as personagens femininas Ruth e Mbubi apresentam ou não os traços propostos pelo Africana Womanism, teoria feminista africana defendida por Clenora Hudson-Weems (1993). Tal teoria enaltece o papel das mulheres africanas em sua sociedade e principalmente evoca o resgate às tradições autóctones. Observa-se que somente a personagem Mbubi poderia ser considerada uma feminista, uma vez que Ruth rende-se aos padrões ocidentais capitalistas, não se identificando mais com a sua cultura africana. Assim, através da análise das representações dessas personagens femininas, esta pesquisa procura contribuir para o campo dos estudos sobre as mulheres africanas. Além disso, busca expandir os conhecimentos sobre os feminismos africanos e, dessa forma, trazer à pauta a questão dos papéis sociais das mulheres africanas na sociedade atual.
Sobre a complementariedade entre os sexos: discutindo as relações entre homens e mulheres nos discursos do feminismo hegemônico e de intelectuais da África Subsaariana
Authors: Barbosa de Aquino Raisa Conceição
Published: October 2022

Desde os seus primórdios o feminismo nascido na Europa e América do Norte tem sido tomado como uma “verdade absoluta” e ponto de partida para discussão de todas as problemáticas que envolvem indistintamente mulheres, tornando-se hegemônico. Nesta discussão, as intelectuais africanas passaram, no entanto, a reivindicar a retomada de suas vozes silenciadas pelo colonialismo que atingiu ferozmente o continente africano e que ainda hoje deixa resquícios. Estas intelectuais apontam para a necessidade de o movimento feminista contextualizar sua luta, levando em consideração a pluralidade das identidades, especialmente no tocante à maternidade, religião, etnia, geração, posição social e atividade econômica, em continente africano, bem como desconstruindo a ideia de patriarcado como uma categoria dada, onipresente e onisciente, universal em todas as relações sociais. O presente trabalho foi realizado através de revisão bibliográfica, catalogando-se algumas das principais intelectuais africanas e pretende identificar e discutir conceitos e concepções de gênero, identificados como fixos/rígidos para as feministas hegemônicas e como fluído de acordo com o entendimento de intelectuais africanas estudadas.
Challenges to Online Pharmacy Classes during COVID 19 Pandemic: cross sectional study in Jordan
Authors: Salama Ali , Altaif Khalil
Published: October 2022

Background: Covid 19 pandemic has had a strong influence on all aspects of life . One of these influence is education. The academic authorities in Jordan as in elsewhere across the world have shifted their method of teaching to online class. After four semester of online teaching it’s important for both teaching staff and students of pharmacy faculties to assess the trends and the preference of students to different methods of online teaching. The purpose of this study was to assess the influence of the COVID19 pandemic on online education for pharmacy students in Jordan’s faculties of pharmacy.

Methods: We emailed a survey to the majority of students in Jordan’s pharmacy faculties during january and february 2022.

Results: We received 230 responses, with 87.2 percent of respondents being female and the majority of the students being pharmacy students. Among the 230 respondents, 75% said they liked combining online and face-to-face training, while 13% said they preferred face-to-face instruction and only 12% said they favored online learning. The major challenges in online teaching during the pandemic are issues with in-person communication (87 percent), student assessment (65 percent) and use of technology tools (35 percent).

Conclusion: Due to the fact that the survey was conducted during the fourth semester with the COVID 19 pandemic, and most students have gained confidence in using online technology and the university IT support, one can conclude that pharmacy students have a high level of confidence in the effectiveness of online pharmacy education.

Published: October 2022

Two new species of Boesenbergia, B. sugudensissp. nov. and B. truncatasp. nov. were discovered in Sabah, Malaysian Borneo. Boesenbergia sugudensis resembles B. imbakensis in that the leaf sheath of the plant is not thickened and in the anther thecae dehiscing by longitudinal slits, but differs in having a longer petiole and tubular calyx. Boesenbergia truncata resembles B. orbiculata by the short petiole and a bilobed calyx, but differs by the truncate leaf base, the acute leaf apex, opposite leaves with a narrower lamina parallel to the ground and anther thecae dehiscing by pores. The new species are described and illustrated in detail.
Akhania, a new genus for Salsola daghestanica, Caroxylon canescens and C. carpathum (Salsoloideae, Chenopodiaceae, Amaranthaceae)
Authors: Sukhorukov Alexander P. , Fedorova Alina V. , Kushunina Maria , Mavrodiev Evgeny V.
Published: October 2022

Genus Salsola s.l. was recently split into several genera of different phylogenetic placements within Salsoloideae, but both taxonomic and phylogenetic relationships of some parts of the former broadly defined Salsola still need to be clarified. A remarkable example is Salsola canescens nom. illegit. ≡ Salsola boissieri, a taxon with tricky taxonomic history that was only recently transferred to the genus Caroxylon (tribe Caroxyleae). Salsola daghestanica, a narrow endemic of Central Dagestan (Russian Federation), was not even included in previous molecular studies of Salsoloideae and therefore still lacks an appropriate estimation of its relationships. Molecular phylogeny constructed here using nuclear and plastid DNA sequence data clearly placed Salsola daghestanica and Caroxylon carpathum as sister taxa and the clade S. daghestanica, Caroxylon canescens (Salsola boissieri), C. carpathum (Salsola carpatha) as a sister of the monophyletic Caroxylon. All three species are distinct from Caroxylon from a morphological standpoint. In conclusion, a new genus, Akhania, was established for these taxa. The detailed distribution of Akhania daghestanica is presented for the first time.
La « remarquable famille Schreber » : une histoire de père en fils et ses exégètes
Authors: Gavarini Laurence
Published: October 2022

Avec « La remarquable famille Schreber », l’auteure revisite les lectures qui ont constitué durant un siècle le cas Schreber comme paradigmatique de la paranoïa, depuis celles de Freud et Lacan, jusqu’au tournant interprétatif des années 1960-1980 qui élargit la problématique de la folie du sujet à l’éducation familiale et plus précisément paternelle, justifiant le sous-titre : « une histoire de père en fils et ses exégètes ». Centrée initialement sur l’étude d’une pathologie, son origine événementielle, son étiologie et sa préhistoire médicale, la focale de l’étude du cas Schreber se déplace et s’élargit à ce qui fait délirer un sujet (l’état psychique d’un père, son éducation tyrannique). Ainsi, des tendances épistémologiques dans la clinique du « cas Schreber » rivalisent, selon qu’elles imputent la causalité psychique à la gouverne du sujet et à la faillite du Nom-du-Père ou à une causalité externe, à la croisée du transgénérationnel et des orientations éducatives du père, symbole d’une « pédagogie noire » fortement dénoncée en Allemagne et dans l’aire anglo-saxonne depuis les années 1970. L’article passe en revue ces différentes lectures et en questionne les manques, particulièrement la fonction des femmes dans la remarquable famille.
Du cas Schreber et de ce qu’on ne doit pas oser faire dans l’éducation : une contribution au débat sur la transmission
Authors: de Lajonquière Léandro , Baldassi D’Arrigo Floriana
Published: October 2022

En un moment historique où la demande adressée aux experts en éducation et formation est de plus en plus présente sous une forme réductionniste et médicalisante, le « cas Schreber » permet de repenser les conditions de possibilité de l’éducation d’un enfant. S’il est souvent mobilisé pour montrer les méfaits d’une éducation qualifiée d’autoritaire, pour nous, il est plutôt l’occasion de montrer les risques délétères des initiatives prétendument scientifiques en éducation, structurées autour du déni de la castration, dont son seul témoignage est la condition nécessaire pour qu’un enfant soit convoqué à habiter un lieu de parole singulier dans une histoire en cours.

La fiscalité environnementale, outil d’une politique publique
Authors: Domingo Laurent
Published: October 2022

La fiscalité française de l’environnement est essentiellement une fiscalité de rendement et qui, alors pourtant que les exigences constitutionnelles n’y font pas obstacle, ne présente pas de caractère réellement incitatif sur les comportements. Cependant, pour être efficace en matière environnementale, l’impôt ne peut être seulement conçu comme un moyen de contrainte, difficilement accepté en général, mais il doit être envisagé comme un outil au service d’une politique publique qui offre des choix de comportements favorables à la préservation de l’environnement.
Évaluation de la douleur induite par la vaccination en fonction du bras d’injection (vaccination SARS-COV-2)

Published: October 2022

Depuis sa découverte, la pratique de la vaccination s’est améliorée de façon continue afin d’offrir une meilleure efficacité et tolérance. Les réactions locales voire diffuses sont souvent évoquées, mais aucune étude ne rapporte de résultats en fonction du bras choisi pour l’injection. Nous avons réalisé une étude observationnelle prospective aux centres de vaccination COVID-19 du GHT des Landes pendant trois semaines. Un questionnaire était remis après la deuxième injection et évaluait les douleurs et gênes du patient lors de la première injection. Durant cette période, 2 797 patients ont reçu leur deuxième injection, 2 487 ont répondu au questionnaire dont 2 301 sont exploitables. La vaccination a été réalisée à 81 % du côté du bras non dominant et à 19 % du côté du bras dominant. Les douleurs/gênes locales ont été rapportées par 47 % des patients sur les deux bras, leur apparition étant survenue le jour même pour la moitié des personnes et le lendemain pour l’autre moitié, avec une intensité moyenne de 3,3 sur une échelle de 10. Les douleurs/gênes diffuses étaient présentes chez 19 % des personnes, quel que soit le côté. Le choix du bras pour l’injection semble ne pas avoir d’influence sur la survenue de douleurs.
Extended DEA method for solving multi-objective transportation problem with Fermatean fuzzy sets
Authors: Akram Muhammad , Shah Syed Muhammad Umer , Al-Shamiri Mohammed M. Ali , Edalatpanah S. A.
Published: October 2022

Data envelopment analysis (DEA) is a linear programming approach used to determine the relative efficiencies of multiple decision-making units (DMUs). A transportation problem (TP) is a special type of linear programming problem (LPP) which is used to minimize the total transportation cost or maximize the total transportation profit of transporting a product from multiple sources to multiple destinations. Because of the connection between the multi-objective TP (MOTP) and DEA, DEA-based techniques are more often used to handle practical TPs. The objective of this work is to investigate the TP with Fermatean fuzzy costs in the presence of numerous conflicting objectives. In particular, a Fermatean fuzzy DEA (FFDEA) method is proposed to solve the Fermatean fuzzy MOTP (FFMOTP). In this regard, every arc in FFMOTP is considered a DMU. Additionally, those objective functions that should be maximized will be used to define the outputs of DMUs, while those that should be minimized will be used to define the inputs of DMUs. As a consequence, two different Fermatean fuzzy effciency scores (FFESs) will be obtained for every arc by solving the FFDEA models. Therefore, unique FFESs will be obtained for every arc by finding the mean of these FFESs. Finally, the FFMOTP will be transformed into a single objective Fermatean fuzzy TP (FFTP) that can be solved by applying standard algorithms. A numerical example is illustrated to support the proposed method, and the results obtained by using the proposed method are compared to those of existing techniques. Moreover, the advantages of the proposed method are also discussed.
Fermat's and Catalan's equations over $ M_2(\mathbb{Z}) $
Authors: Li Hongjian , Yuan Pingzhi
Published: October 2022

Let $ A = \begin{pmatrix} a & b \\ c & d \end{pmatrix}\in M_2\left(\mathbb{Z}\right) $ be a given matrix such that $ bc\neq0 $ and let $ C(A) = \{B\in M_2(\mathbb{Z}): AB = BA\} $. In this paper, we give a necessary and sufficient condition for the solvability of the matrix equation $ uX^i+vY^j = wZ^k, \, i, \, j, \, k\in\mathbb{N}, \, X, \, Y, \, Z\in C(A) $, where $ u, \, v, \, w $ are given nonzero integers such that $ \gcd\left(u, \, v, \, w\right) = 1 $. From this, we get a necessary and sufficient condition for the solvability of the Fermat's matrix equation in $ C(A) $. Moreover, we show that the solvability of the Catalan's matrix equation in $ M_2\left(\mathbb{Z}\right) $ can be reduced to the solvability of the Catalan's matrix equation in $ C(A) $, and finally to the solvability of the Catalan's equation in quadratic fields.
Large-pose facial makeup transfer based on generative adversarial network combined face alignment and face parsing
Authors: Li Qiming , Tu Tongyue
Published: October 2022

Facial makeup transfer is a special form of image style transfer. For the reference makeup image with large-pose, improving the quality of the image generated after makeup transfer is still a challenging problem worthy of discussion. In this paper, a large-pose makeup transfer algorithm based on generative adversarial network (GAN) is proposed. First, a face alignment module (FAM) is introduced to locate the key points, such as the eyes, mouth and skin. Secondly, a face parsing module (FPM) and face parsing losses are designed to analyze the source image and extract the face features. Then, the makeup style code is extracted from the reference image and the makeup transfer is completed through integrating facial features and makeup style code. Finally, a large-pose makeup transfer (LPMT) dataset is collected and constructed. Experiments are carried out on the traditional makeup transfer (MT) dataset and the new LPMT dataset. The results show that the image quality generated by the proposed method is better than that of the latest method for large-pose makeup transfer.
DESIGN FOR AN ALL-ELECTRIC DESIGN FOR SUPPORT IN INITIAL DESIGN USING THE NETWORK BLOCK APPROACH: A SUBMARINE EXAMPLE
Authors: Mukti M H , Pawling R J , Andrews D J
Published: October 2022

The layout of the Distributed Ship Service Systems (DS3) can be a major constraint both on the location of hull berth unit and of transverse bulkheads, with implications for conducting maintenance and so contribute to submarine Sustainability. This paper proposes a new early-stage ship design (ESSD) approach that would aid the designer to consider DS3 features physically and logically much earlier in the design process. The approach is termed the Network Block Approach and combines the advantages of the UCL 3D physically based ship synthesis Design Building Block (DBB) approach and the
network-based approach for distributed ship service systems (DS3) synthesis already proposed for naval combatants. The proposed Network Block Approach enables modelling of individual spaces to locate and zone various DS3 components and take account of hull unit boundaries and major bulkheads. The paper discusses the importance of DS3 routing to warship Sustainability through the complexity of a submarine design example and shows how the proposed approach enables this to be explored in ESSD.
OBSOLESCENCE MANAGEMENT TO ENABLE SUPPORTABILITY FOR THE AUTONOMOUS WARSHIP
Authors: Flint T
Published: October 2022

Rapid obsolescence is often a consequence of rapid technology development. Modern warships are operating in an era of increased technological development, with complex systems having a redevelopment cycle significantly shorter than the lifetime of the ship. The Autonomous Warship concept is one such area and designers must take this rapid development into account to ensure Navies remain at the forefront of technology without early systems experiencing a tsunami of obsolescence. Obsolescence must be considered early in the life cycle of AI and its connected systems to reduce the amount of redundant technology in the future. Advances in AI and mechatronics result in capability improvements, but also increase obsolescence driven waste and supportability issues. This means that effective, proactive obsolescence management is more important than ever to maintain capability, reduce environmental waste and eliminate unnecessary
costs. This paper will seek to outline options to increase system adaptability and reduce the looming obsolescence risks of technological advancement.

Authors: Liu Haiyan , Dong Yajing , Li Lingwan
Published: October 2022

For college students, interpersonal skills (IS) are very necessary for them to build social networks and gain entrepreneurial resources, the level of their IS has a certain influence on their entrepreneurial performance (EP), and it’s needful to explore the mechanism of such influence. For this reason, this paper studied the correlation between college students’ IS and EP. At first, the paper gave a theoretical framework for analyzing the said influence mechanism. Then, focusing on the synchronization of IS and EP, this paper used the entropy to measure the sync correlation between the two, so as to quantify the joint improvement speed of the two, and six quantitative indicators had been adopted in the paper, including multi-scale sample entropy, multi-scale fuzzy entropy, cross-sample entropy, transfer entropy, de-trend correlation coefficient, and temporal correlation. At last, relevant experiments were conducted and the analysis results of the correlation between the two were given.
An RHMIoT Framework for Cardiovascular Disease Prediction and Severity Level Using Machine Learning and Deep Learning Algorithms
Authors: Patro Sibo Prasad , Padhy Neelamadhab
Published: October 2022

Cardiovascular disease is one of the deadliest diseases in the world. Accurate analysis and prediction for real-time heart disease are highly significant. To address this challenge, a novel IoT-based automated function monitoring system to promote the e-healthcare system is proposed. The proposed remote healthcare monitoring system uses an IoT framework (RHMIoT) using deep learning and auto encoder-based machine learning algorithms to accurately predict the presence of heart disease. The RHMIoT framework contains two phases: the first phase is to monitor the severity level of the heart disease patient in real-time, and the second phase is used in the medical decision support system to predict the accuracy level of heart disease. To train and test the open-access Framingham dataset, various deep learning and auto encoder-based machine learning techniques are used. The proposed system obtains an accuracy of 0.8714% using the auto encoder-based kernel SVM algorithm compared to other approaches.
Load Balancing Approaches in Cloud and Fog Computing Environments
Authors: Shakeel Hiba , Alam Mahfooz
Published: October 2022

Cloud and fog computing are modern technologies that handle multiple dynamic user requests. Cloud provides demand-based services to users over the internet on pay-as-you-go basis. Fog handles real-time requests that are received from smart devices. Millions of requests arrive at the cloud-fog layer, often leading to overloaded virtual machines (VMs). Load balancing (LB) is an important issue for cloud-fog systems and has been proved to be an NP-hard problem. It is essential as it distributes the load equally among VMs to properly utilize resources and improve quality of service (QoS). Therefore, this paper presents a complete classification of LB algorithms and also a comprehensive study using heuristic, meta-heuristic, and hybrid approaches in cloud and fog computing environments. The main goal of this paper is to highlight the importance of LB to overcome the challenges of the systems. This study reviews papers of the last seven years and systematically discusses them using various tables and pie charts. Finally, the paper concludes with the research gaps and future insights.
Impact of CPEC Transit Routes on Environmental Sustainability
Authors: Nazir Sajid , Raza Khawaja Masood
Published: October 2022

Transit routes play a significant role in the transportation of goods and services in a supply chain. A short and safe transit route improves overall transport efficiency and environmental sustainability while reducing logistical costs. Since China's need of oil is increasing day by day, the logistics service providers (LSPs) continually seek a quick and safe transit route for faster demand response time with a low price. China Pakistan Economic Corridor (CPEC) is a new hope for LSPs for the supply of oil and other goods to China with a short and safe transit route. The traditional sea routes of oil supply are very long and time-consuming. However, through the development of CPEC, the results have shown a massive decline in route distance, delivery time, and cost that will help the LSPs with continuous supply with low costs and promoting environmental sustainability.

Authors: Ngo Thien Van
Published: October 2022

This research has been conducted to examine students' perceptions of perseverance in online learning activities through implementing flipped learning for the students at the college level. The data have been gathered through an online questionnaire from 325 first-year students attending physics courses in the Department of Mechanical Engineering at Cao Thang Technical College. Cronbach's Alpha is performed to examine the internal consistency of the associated factors. The exploratory factor analysis is used to extract the variables and measure the factor loadings. Nine factors have been found to evaluate students' perseverance through a physics course, including goal and learning outcome, goal commitment, assessment strategy, value of learning activities, learning task, ability to perform tasks, ability to control learning, types of interactions, and types of presence. The relationship between the nine independent variables and the dependent variable is run by using the linear regression model. The results showed that nine independent variables positively impact students' perseverance.

Emotion is a feeling that can be expressed by different mediums. Emotion analysis is a key task in NLP which is responsible for judging the emotional tendency of texts. Currently, in a complex multi-semantic environment, it still suffers from poor performance. Traditional methods usually require human intervention, while deep learning always has a trade-off between local and global features. To solve the problem that deep learning models generalize poorly for emotion analysis, this article proposed a semantic-enhanced method called RA-CNN, a classification model under a multi-semantic environment. It integrates CNN for local feature extraction, RNN for global feature extraction, and attention mechanism for feature scaling. As a result, it can acquire the correct meaning of sentences. After experimenting with the hotel review dataset, it has an improvement in positive feeling classification compared with the baseline model (3%~13%), and it showed a competitive performance compared with ordinary deep learning models (~1%). On negative feeling classification, it also performed well close to other models.

Published: October 2022

Objective:

To compare the benefits of enhanced recovery after surgery (ERAS) pathways with traditional pathways for adult patients undergoing laparoscopic appendectomy.

Methods:

We looked for publications using the keywords “Enhanced Recovery After Surgery,” “Fast-track Surgery,” “Laparoscopic Appendectomy,” and “Laparoscopic Appendicectomy” in PubMed/Medline, Embase, and the Cochrane library. Operative time, lesser length of stay, oral intake timing, readmission rate, pain/satisfaction levels, readmission rate, and surgical site infections were recorded and analyzed.

Results:

A total of 95 articles from registers and 161 articles from databases were identified. Three eligible studies were included. The ERAS pathways had a lesser length of stay [Z=2.06, MD= -1.05, 95% CI=(-2.04, -0.05), P=0.04] and an earlier start to postoperative feeds [Z=6.22, MD= -267.49, 95% CI=(-351.80, -183.19), P<001].

Conclusions:

ERAS pathways have a shorter length of stay and earlier postoperative feed initiation for adult patients undergoing laparoscopic appendectomy compared with standard care. Both approaches have similar operative time, surgical site infection incidence, and readmission rate.

Clinical registration:

This review is registered with INPLASY202280005.

Authors: Tontu Furkan , Asar Sinan , Oren Bilgin Beyza
Published: October 2022

Objective:

To investigate the effect of the variability of Nas, Cls, Ks, lactate values and sodium effect (NaEffect), chloride effect (ClEffect), non-lactate strong ion difference (SIDnl) values calculated according to Stewart’s approach on predicting intensive care unit (ICU) mortality.

Methods:

The study was conducted on 1539 patients, retrospectively. Serum Na (Nas), serum Cl (Cls), serum K (Ks), serum Ca (Cas), serum Mg (Mgs), lactate, pH values and SIDnl, NaEffect, ClEffect, APACHE II (first, last), and SOFA (first, last) scores were recorded. Radiometer ABL 800 (Denmark) was used for blood gas analysis. The variability of each parameter was calculated. The effect of variability of each parameter on 30-day ICU mortality was analyzed.

Results:

The variability of lactate (P<0.001, OR=0.580, 95% CI=0.505-0.652), pH (P=0.001, OR=0.004, 95% CI=0.000-0.104), NaEffect (P<0.001, OR=0.550, 95% CI=0.378-0.592), Ks (P<0.001, OR=0.385, 95% CI=0.244-0.565) values were protective factors of ICU mortality and Cls value was a risk factor (P=0.004, OR=1.095, 95% CI=1.024-1.164). Variability of ClEffect, SIDnl values did not affect ICU mortality.

Conclusions:

The variability of electrolytes is important. Electrolyte, effects, and lactate variability can guide treatment and fluid applications in ICU.

Introduction:

There is a paucity of data in the scientific literature on the morbidity and mortality of bariatric and metabolic surgery (BMS) in individuals suffering from Type 2 diabetes mellitus (T2D). The current study is a secondary analysis of the GENEVA dataset to understand this.

Materials and Methods:

Logistic regressions were performed to investigate the influence of diabetes on complication rates and procedure selection. Ethical approval was not required.

Results:

One thousand four hundred and seventy-five of these patients were suffering from T2D at the time of the surgery (416 diet-treated type 2 diabetes), 806 oral agent-treated type 2 diabetes, and 253 insulin-treated type 2 diabetes [ITD]). Six hundred and fifty (44.1%) of these patients underwent laparoscopic sleeve gastrectomy (LSG); 487 (33%) underwent Roux-en-Y gastric bypass; 230 (15.6%) underwent a one anastomosis gastric bypass (OAGB); and 108 (7.3%) underwent some other procedures. The 30-day mortality of BMS in those without T2D was 0.07% (4/5609) as compared to 0.4% (6/1475) and 0.8% (2/253) in those with T2D and ITD, respectively. 7.9% of those with T2D developed a 30-day complication compared to 6.5% without T2D (P = 0.0475). There was an increased risk of complications in patients with ITD on univariate and multivariate analysis. Patients with T2D were significantly less likely to undergo an LSG and significantly more likely to undergo an OAGB.

Conclusions:

ITD patients undergoing BMS experienced significantly higher 30-day morbidity and mortality. Although LSG was the most common procedure in patients with T2D, these patients were less likely to undergo LSG than patients without T2D.

To increase the success rate of the in vitro production (IVP) system of embryos in buffalo, it is necessary to improve parameters. This field requires more research since its results are low compared to cattle. In this study carried out in Colombia, a modification of the methodology to produce buffalo IVP embryos is described, and 24 non-lactating females, aged 4 to 11 years old were included. Follicular wave was synchronised by ablation of the follicles within the ovary, seven days later all follicles were aspirated to obtain oocytes for maturation, fertilisation and embryo production. For all culture media used, animal protein was avoided. Culture media were supplemented with growth factors and other molecules associated with embryonic development. Special care was taken in adding supplements to protect the zygotes against the harmful effect of oxygen free radicals in the culture medium. Two aspiration series were performed 15 days apart. The average number of oocytes obtained by aspiration was 11.33, the number of blastocysts was 3.05, and the obtained blastocyst production rate (36.2%) was higher than literature reports for this species; we hypothesise that this increase is associated with the supplements added. It was possible to observe a female that produced 50 oocytes. Subsequent research is needed to evaluate the effect of the medium on embryo quality and pregnancy rates. A cost analysis of the new proposed medium is required, since all supplements must be imported and handled with a cold chain of up to -80oC, making it more expensive and restricting widespread use. Finally, it is shown that with three embryos per aspiration, at least one pregnancy can be successful after the aspiration, which is one of the objectives of the IVP system.

Listeria je patogen prenosiv hranom i predstavlja veliku opasnost za ljudsko zdravlje. Teški su simptomi praćeni visokom stopom mortaliteta većinom prouzročeni L. monocytogenes. Bez obzira na politiku nulte tolerancije, rod Listeria je još uvijek prisutan u sirovim proizvodima i proizvodima spremnim za konzumiranje, predstavljajući veliku opasnost za zdravlje ljudi. Za sada još u bliskoj budućnosti ne postoje studije o kontaminaciji hrane vrstama Listeria u Bosni i Hercegovini. Ovim istraživanjem htjeli smo dobiti osnovne podatke o količini kontaminiranosti hrane ovim patogenom. U studiji je analizirano ukupno 238 uzoraka hrane, pri čemu su u 105 uzorka bile različite vrste sirove hrane te 133 uzorka hrane spremne za konzumaciju (gotove hrane). Od ukupno 238 uzoraka, 18 uzoraka je bilo pozitivno na Listeria vrste. Nakon izolacije i detekcije, konfirmacija pozitivnih izolata Listeria spp. je provedena pomoću biokemijskog kita API® Listeria.
