New hematological biomarkers in patients with atrial septal aneurysm

Mean platelet volume/platelet count (MPV/PC) and monocyte/lymphocyte (MLR), neutrophil/lymphocyte (NLR) and platelet/lymphocyte (PLR) ratios are new hematological markers showing systemic platelet activation and inflammation. The aim of this study was to compare new hematological markers in patients with atrial septal aneurysm (ASA) and to determine their relationship in patients with ASA. 70 ASA and 47 healthy subjects (as control group) were included in the study. Demographic, clinical, echocardiographic and hematological values of the groups were recorded. MPV/PC ratio and MLR were significantly higher in ASA group compared to control group (0.03 ± 0.013 vs 0.02 ± 0.009, P=0.02 and 0.27 ± 0.15 vs 0.22 ± 0.08, P=0.03). NLR and PLR were not different between the groups. The presence of ASA was positively correlated with MLR and MPV/PC, left atrium, left ventricular (LV) septum thickness and LV posterior wall thickness, while red blood cell (RBC) was negatively correlated. However, in multivariate linear regression analysis, there was an independent relation between the presence of ASA and MPV/PC, MLR, LV septum thickness and RBC. We found that MPV/PC ratio and MLR from new hematological biomarkers are independent predictors for the presence of ASA.
FAPOHUNDA et al.: EFFECT OF CHANGING CEMENT GRADE DURING CONCRETING OPERATONS

*Corresponding author: christopher.fapohunda@fuoye.edu. ng doi: http://dx.doi. org/10.4314/njtd.v17i3. 6 ABSTRACT: Many research efforts have been carried out, in a quest to produce mix design information that will guide the concrete and construction industry on how to achieve different concrete strengths, using the different grades of cement available. This is with a view to arresting the rampant collapse of buildings in Nigeria. The work presented in this paper is the result of investigation carried out to determine effects of changing cement grade, while casting a structural member, on the strength behaviour of the concrete. Two types of cement grades: 32.5 R and 42. 5 R were used for this research. In this investigation, the chemical and physical properties of the cement were determined. Consistency and setting times of mortar specimens from the two cement grades were also determined. Concrete samples made from the two cement grades 32.5 R and 42.5 R were evaluated for workability, density, compressive and tensile strengths at water/cement ratios of 0.40, 0.50 and 0.60. The results showed that the cement grade 42.5 consistently developed higher densities at all the water/cement ratios considered. This may be as a result of unforeseen additional dead load at the design stage, which would now amount to underestimation of dead load and thus design load. The results also showed that at higher water/cement ratios, the cement grade 42.5 R has densities exceeding the 2400 kg/m recommended by BS 8110. Furthermore, the concretes produced with cement grades of 32.5 R and 42.5 R have different strength development pattern and developed different 28-day compressive strength. Thus, it can be concluded that the action of changing the cement grade during concreting, for the same structural member is not supported by the national code, and will not result in safe and durable concrete.
Comparison of complete blood count parameters of panic attack and panic disorder

Although complete blood count (CBC) parameters in panic disorder (PD) are frequently studied, there is no data on panic attacks (PA). In this retrospective study, CBC parameters of patients diagnosed with PD (n=63) and PA (n=61) were compared with the data of healthy subjects (n=41). The groups were similar in terms of age (p=0.395) and gender (p=0.567). There were significant differences between the PD and the PA groups in terms of percentage of lymphocyte (p
Generalized Invariant Risk Minimization: relating adaptation and invariant representation learning

If faced with new domains or environments, a standard strategy is to adapt the parameters of a model trained on one domain such that it performs well on the new domain. Here we introduce Generalized Invariant Risk Minimization (G-IRM), a technique that takes a pre-speciﬁed adaptation mechanism and aims to ﬁnd invariant representations that (a) perform well across multiple different training environments and (b) cannot be improved through adaptation to individual environments. G-IRM thereby generalizes ideas put forward by Invariant Risk Minimization (IRM) and allows us to directly compare the performance of invariant representations with adapted representations on an equal footing, i.e., with respect to the same adaptation mechanism. We propose a framework to test the hypotheses that (i) G-IRM outperforms IRM, (ii) G-IRM outperforms Empirical Risk Minimization (ERM) and (iii) that more powerful adaptation mechanisms lead to better G-IRM performance. Such a relationship would provide a novel and systematic way to design regularizers for invariant representation learning and has the potential to scale Invariant Risk Minimization towards real world datasets.

The lowest mean is 2.4 for the Efficiency dimension. The overall mean for usability is 2.8 which reflect the level of usability for the PSAU mobile application. The results of this study should be useful to IT deanships and related policymakers at the university level with empirical evidence about the issues and problems that faced users of mobile applications in higher educational institutions in KSA; and helping in developing high-quality mobile application.
Nativeness Assessment for Crowdsourced Speech Collections

Access to large amounts of annotated data is a challenge for companies developing high-quality AI-based services. Crowdsourcing presents itself as a solution to this growing need for training data, by gathering and distributing work across a large pool of human contributors. This, however, comes at a cost: the difﬁculty to source the right crowd and maintain data quality. Regarding speech, a critical aspect of data quality relates to the veriﬁcation of crowd participants as native speakers of a speciﬁc language. This work investigates the use of automatic Nativeness Classiﬁcation (NC) solutions to tackle this problem, integrating a variant-sensitive nativeness classiﬁer component in the speech collection pipeline for Portuguese (European and Brazilian variants) and English (American, British and Indian). By rating individual recordings according to their nativeness, it is possible to both automatically discard substandard work and prevent certain contributors to continue to participate in the collection. Herein, three different speaker-embedding-based frameworks are tested: i-vector, x-vector, and h-vector. Results show that the proposed system based on h-vector outperforms the baseline system with a 8% relative improvement.

Therapeutic approaches to children with enuresis: A retrospective study

Enuresis is a common pediatric condition and there are different treatment options. This study aimed to evaluate treatment options for enuresis in a sample of the child and adolescent psychiatry clinic. The data and treatment results of 98 patients (mean age: 10.38±2.15 years, range=6-16 years) diagnosed with enuresis between 1 May 2015 and 1 October 2020 were retrospectively reviewed. We found that 57 of the patients had previously applied to the hospital for enuresis, and 14 of them have applied to child and adolescent psychiatry, 10 of them to pediatric surgery, 20 of them to other branches of pediatrics, and 13 of them to the urology clinic. In previous hospital applications, behavioral treatment only had been applied to 40.4% of the patients, and pharmacotherapy had been applied in 59.6% of the patients. On the other hand, in the child and ado-lescent psychiatry clinic, 26.5% of the patients received behavioral treatment only, and 73.5% used drugs along with behavioral treatment, and the most frequently preferred drugs were imipramine (oftenest) and desmopressin. Also, the rates of psychiatric comorbidity in those who received medical treatment were significantly higher than those who treated behavioral treatment only. In conclusion, this study revealed that different clinical branches apply different treatment approaches to enuresis. In child and adolescent psychiatry, imipramine was the most commonly used agent in medical treatment, and this has been attributed to the high rate of psychiatric comorbidity
Adult Onset Still ’ s Disease ( AOSD ) : A rare condition with a classic clinical presentation

Introduction: Superior vena cava syndrome is described as the obstruction of blood flow through the superior vena cava. The literature reports that the incidence of this pathology varies from 1 case in every 650 inhabitants and 1 case in every 3 100 inhabitants. Since this condition is very rare in the pediatric population, no clear figure has been reported regarding its incidence in children. The use of a central venous catheter in newborns is a risk factor for this condition, as it may cause a thrombus due to the inflammatory reaction against the device. Therefore, it is necessary to initiate anticoagulation management and remove the catheter. Case presentation: Premature male newborn, (31.4 weeks gestation), with acute respiratory distress syndrome, early neonatal sepsis, pneumonia, necrotizing enterocolitis on 2 occasions, intestinal obstruction due to adhesions and intestinal volvulus. At 90 days of age, he presented thrombosis of the superior vena cava without involvement of the jugular and subclavian vein junction in the right atrium. Anticoagulant management was started, but given his unfavorable evolution, a multidisciplinary medical board was held to assess the risks, benefits, and treatment options in this age group. It was decided to start intracavitary tissue plasminogen activator treatment associated with mechanical thrombectomy and angioplasty of the superior vena cava. 120 case reports Vol. 6 No. 2: 118-27 Due to the difficulty of conducting clinical trials in this population and the rates of major bleeding complications obtained with thrombolytic therapies, there is very little information available on the use of tissue plasminogen activator in newborns. For this reason, alteplase is seldom considered as the therapy of choice. However, in patients with life-threatening thrombosis, such as the present case, the results obtained in adults could be extrapolated in search of a favorable outcome. Conclusions: Fibrinolytic therapy is a way to reduce the size of the thrombus, but it dramatically increases the risk of bleeding; consequently, these patients must be strictly monitored. In pediatric populations, due to the diameter of the blood vessels, thrombectomy is difficult to perform; additionally, recurrent thrombosis and the need for transfusion of blood products are frequent.

Objectives: The ideal remineralization system should provide sufficient ion reserves to provide mineral gain on deeper surfaces, as well as being biocompatible and easy to apply with no adverse effect. The aim of this study was to evaluate the remineralization efficiency of dentifrice form of nanohydroxyapatite alone and its combination with fluoride on initial enamel lesions in primary teeth by micro-CT and SEM. Materials and Methods: The enamel surfaces of 30 extracted primary incisors were treated with nano-hydroxyapatite based (nHAP), nanohydroxyapatite-fluoride-containing (nHAP+F) and fluoride-containing dentifrice (F), respectively after the pH cycle. Mineral gain and surface properties were evaluated by micro-CT and SEM. Results: nHAP group provided more mineral gain than fluoride containing paste groups but there was no statistically significant difference (p>0.05) according to the micro-CT evaluations. In SEM images, the micropores were completely covered with an apatite layer and mineral precipitations were observed to be wider and more pronounced in the nHAP group. Calcium fluoride crystalline structures exhibited non-homogeneous globular precipitations in the F Group. Conclusions: It was concluded that nHAP dentifrice is as effective as fluoride dentifrice on initial enamel lesions in primary teeth with less cariesresistant enamel surface and therefore it can be safely used.
Secure Blockchain-Based Data-Sharing Model and Adoption among Intelligence Communities

— Data sharing among the intelligence communities is important to consolidate data analysis, which will support decision-making process to preserve the security of the nation. Data sharing within an intelligence community could be more practical if an online secure data sharing mechanism is available. However, sharing data between various parties is complicated due to the confidentiality aspect and the risk of exposure to unauthorised users and attackers. Hence, this paper proposes a secure blockchain-based data-sharing model for the intelligence community. The mechanism, rules and related policies are discussed in detail in this paper. Based on the proposed model, the intention to use this model was measured using the technology readiness and acceptance model (TRAM). This study applied four technology readiness dimensions namely optimism, innovativeness, discomfort, and insecurity to measure their relationship with the Technology Acceptance Model (TAM). The findings indicated that personality traits and feelings can influence the adoption process and intention to use blockchain-based data-sharing model for system integration within the intelligence community. This study proved that blockchain technology can be applied in a data-sharing model specifically designed for the intelligence community based on the designated dimension.
Factors Influencing the Intention to Buy Fashionable Apparel via Online Platforms: An Empirical Evidence from Malaysia

The Industrial Revolution 4.0 and the recent Covid-19 pandemic has further boosted e-commerce activities worldwide, including Malaysia. Past studies have been inconclusive in explaining the ideal factors which underlie the intention of buying fashionable apparel via online platform. Thus, this study investigates as to whether apparel characteristics, platform features, and promotion have a significant positive influence on the intention to buy fashionable apparel via online platforms. A total of 306 samples were collected among Malaysian adult consumers. The results of the analysis showed that apparel characteristics impose the strongest positive influence on the intention to buy fashionable apparel via online platforms, followed by platform features and promotion. The study enriches the body of knowledge by demonstrating the impact of the underlying factors in determining the intention to buy fashionable apparel via online platforms based on the Theory of Planned Behavior. The practical implications reveal that marketers should enhance the characteristic of apparel available online, the features of the online platforms used and the promotional price of their online deals. Limitations and suggestions for future studies are also presented.
for Iterative

— Histograms of second-order derivatives are generated from the pixel data of MRI images. The histograms are then used to calculate a factor that is to be used for iterative processing. The factor is intended to limit the number of iterations, with the goal of preventing further loss of detail. The factor uses two conditions that depend on the profiles of the histograms. The methodology uses sample MRI images and versions of these images with Rician noise introduced into them. The noisy images are subjected to iterative noise reduction with a recursive averaging filter. The control tests in the methodology use the ground truth images to limit the number of iterations, with PSNR and SSIM peaks used as the measurements for determining when the iterations stop. The other tests use the proposed termination factor for the limitation. The results of the tests are compared to determine the effectiveness of the termination factor. The proposed termination factor does not cause divergence, but there are still different numbers of iterations in the case of MRI images with image subjects that have discrete regions and details resembling noise. The tests also reveal that differences between the histograms of derivatives and Laplace curves have to be retained in order to prevent loss of information.
HEAVY METAL RESIDUES IN IMPORTED FROZEN FISH AND PANGASIUS HYPOPHTHALMUS (BASA) FISH FILLETS

A B S T R A C T To estimate the levels of mercury, cadmium and lead in imported frozen Pangasius hypophthalmus (P. hypophthalmus) fillets and Sardine; 70 random samples (35 of each) were collected randomly from different fish markets in Qalyubia and Gharbia governorates. The obtained results revealed that the mean levels of mercury, cadmium and lead were 0.57±0.06, 0.11±0.01 mg/kg and 0.15±0.01 in the examined samples of P. hypophthalmus and 0.51±0.04, 0.14±0.02 and 0.09±0.01 mg/kg in sardine, respectively. The levels of mercury and lead were significantly (p<0.05) higher in P. hypophthalmus as compared with sardine. Moreover, the majority of the examined fish samples, particularly, P. hypophthalmus exceeded the safe permissible limits. In this respect, 25.71%, 14.29% and 20% of the examined samples of P. hypophthalmus and 17.14%, 11.43% and 8.57% of the examined samples of sardine were over the higher permissible limits recommended by EOS [10] for mercury, cadmium and lead levels, respectively. In conclusion, the examined samples of P. hypophthalmus were significantly more polluted with high levels of toxic metals especially mercury and lead which seriously distress human health. Therefore, measures should be put in place to reduce the exposure to a minimum, and the daily intake should be set in accordance with the present findings.
Stratospheric water vapor feedback

We show here that stratospheric water vapor variations play an important role in the evolution of our climate. This comes from analysis of observations showing that stratospheric water vapor increases with tropospheric temperature, implying the existence of a stratospheric water vapor feedback. We estimate the strength of this feedback in a chemistry–climate model to be +0.3 W/(m·K), which would be a significant contributor to the overall climate sensitivity. One-third of this feedback comes from increases in water vapor entering the stratosphere through the tropical tropopause layer, with the rest coming from increases in water vapor entering through the extratropical tropopause.

Back to the Coordinated Attack Problem

Abstract We consider the well-known Coordinated Attack Problem, where two generals have to decide on a common attack, when their messengers can be captured by the enemy. Informally, this problem represents the difficulties to agree in the presence of communication faults. We consider here only omission faults (loss of message), but contrary to previous studies, we do not to restrict the way messages can be lost, i.e., we make no specific assumption, we use no specific failure metric. In the large subclass of message adversaries where the double simultaneous omission can never happen, we characterize which ones are obstructions for the Coordinated Attack Problem. We give two proofs of this result. One is combinatorial and uses the classical bivalency technique for the necessary condition. The second is topological and uses simplicial complexes to prove the necessary condition. We also present two different Consensus algorithms that are combinatorial (resp. topological) in essence. Finally, we analyze the two proofs and illustrate the relationship between the combinatorial approach and the topological approach in the very general case of message adversaries. We show that the topological characterization gives a clearer explanation of why some message adversaries are obstructions or not. This result is a convincing illustration of the power of topological tools for distributed computability.
