A Weighted Voting Classifiers Ensemble for the Brain Tumors Classification in MR Images

The appropriate treatment of cancers critically depends on the precise identification of the tumor types. The Magnetic Resonance Imaging (MRI) provides a non-invasive approach for detecting the tumors and classifying their types. Computer-aided diagnosis (CAD) systems using image analysis and machine learning algorithms assist radiologists in making error-free decisions. This paper presents an integrated approach for the segmentation and classification of three types of brain tumors (i.e. meningioma, glioma, and pituitary tumor) in real MRI images. First, the images quality is enhanced by removing the noises using wiener and median filters. Then, the support vector machine (SVM) classifier is performed to segment the MR image. Following this, 42 features are extracted, among which eleven most practical features are chosen by the Differential Evolution (DE). Using the selected features, tumor slices are categorized using the k-nearest neighbors (KNN), the weighted kernel width SVM (WSVM) and the histogram intersection kernel SVM (HIK-SVM) classifiers. Afterwards, these classifiers are combined using a multi-objective differential evolution (MODE)-based ensemble technique to attain the classification accuracy of 92.46%, evaluated using the five-fold cross validation method. The results of the proposed approach are also compared with the experienced radiologist ground truth which shows that the proposed MODE-based ensemble technique is able to achieve high classification scores, measured also by sensitivity and specificity indices.
The experience of returning home after surviving cardiac arrest: A narrative inquiry

Surviving a cardiac arrest is a tumultuous experience. Although the incidence of cardiac arrest and influencing factors are well researched, little is known of survivors’ experiences as they return home from hospital. This article aims to explore survivors’ experiences of returning home after surviving a cardiac arrest. Four females and 13 males, all independently living cardiac arrest survivors, were recruited using purposive and snowball sampling techniques and participated in individual in-depth interviews over a six-month period. This inquiry follows COREQ guidelines and data were analysed using narrative inquiry where key threads were identified. Findings indicate that a cardiac arrest is a catastrophic event where the survivor has to accept and adjust mentally, physically and socially, often leading to insecurity about the future. The cardiac arrest impacts all aspects of life on return home, including the ability to work and to drive, accepting added medical appointments and medication regimens. Healthcare professionals can learn from survivors’ narratives to support holistic care, considering survivors’ experiences in their transition home and back to reality as a cardiac arrest survivor.
Anxiolytic Mechanism(S) and Corticosterone-Attenuating Effect of Hydroalcoholic Leaf Extract of Tapinanthus globiferus Mistletoe Growing on Azadirachta indica Tree

Similar pharmacodynamic mechanism(s) often underlie drug actions and toxicities of anxiolytic agents and medicinal extracts. Extracts of Tapinanthus globiferus and related plant species have been reported with anxiolytic activities. But mechanistic evaluations on these plant extracts are few. This study investigated the anxiolytic mechanism(s), including the corticosterone-attenuating effect, of hydroalcoholic Tapinanthus globiferus (HATG) leaf extract harvested from Azadirachta indica host tree in the mouse elevated zero-maze and restraint-induced acute stress paradigms using per cent open segment time (%OST) and brain/plasma corticosterone levels as endpoints, respectively. The results show that anxiolytic activity (%OST) of 150 mg/kg HATG leaf extract was reversed by pretreatment with 5 mg/kg caffeine (HATG alone, 10.90±1.73;HATG+Caffeine, Original Research Article Umarudeen and Magaji; JOCAMR, 10(1): 14-23, 2020; Article no.JOCAMR. 57972 15 8.66±1.74), 2 mg/kg methysergide (MTD) (HATG alone, 98.70±14.98; HATG+MTD, 74.20±10.82) and 5 mg yohimbine (HATG alone, 120.10±10.72; HATG+Yohimine, 78.44±13.92) but not by 0.5 m/kg atropine (HATG alone, 104.60±25.31; HATG+Atropine, 105.40±11.85), 0.5 mg/kg flumazenil (HATG alone,80.27±9.69; HATG+Flumazenil, 80.75±10.19), 2 mg/kg cyproheptadine (HATG alone, 88.67±16.44; HATG+Cyproheptadine, 92.11±12.58), 0.2 mg/kg haloperidol (HATG alone, 74.11±17.33; HATG+Haloperidol, 94.00±32.54) and 5 mg/kg naloxone (HATG alone, 94.30±10.84; HATG+Naloxone, 95.30±6.86). The results also indicate HATG leaf extract (at 50, 150, 500 and 1500 mg/kg) caused largely dose-dependent and significant (p<0.05) attenuations in brain/plasma corticosterone levels (5.64±0.66/3.91±0.44,3.78±0.39/3.39±0.38, 4.26±0.34/3.22±0.18 and 2.74±0.51/2.74±0.22), respectively, in extractcompared to distilled water(5.93±0.60/4.56±0.37) and diazepam-treated (2.34±0.19/2.44±0.29) mice subjected to restraint-induced acute stress. These findings suggest anxiolytic mechanism(s) of the extract may involve its interactions with the adenosine, non-5HT2 serotonin, alpha (α)2 receptors and the hypothalamus-pituitary-adrenal (HPA) axis. This study may constitute the first mechanistic and corticosterone modulation report on the extracts of this parasitic medicinal plant and may benefit from confirmatory radio-labelled binding assays in subsequent studies.
Effects of weight and storage duration of hatching eggs of Indonesian Local Chicken on several measures of internal quality and hatchability

Hatchability and some internal qualities of hatching eggs of Indonesian Local Chicken (ILC) were investigated from different egg weights and storage durations. A total of 950 eggs (including 120 eggs for internal quality measurements) were collected and selected from a flock of INC aged 55 – 60 weeks reared in the University Farm, during 3-week production not consecutively. The research was arranged as a 6 x 4 factorial based on a randomized completely block design, using 6 levels of egg storage duration of 1, 2, 3, 4, 5 and 6 days, and 4 levels of egg weight (EW), 3 replication of unequal individual amount in each replication unit. Before storing, the eggs in each group were classified according to their weights: (1) ≥35 - <40; (2). 40 -< 45; (3) ≥ 45 - <50 and (4) ≥ 50 - < 55gr. All eggs were sterilized using alcohol 70%, numbered and stored at room temperature 26-27°C with relative humidity 60-70%. The results indicated that the proportion of egg weight loss of lighter egg at different storage duration was mostly significantly higher (P<0.05) than the heavier one. During storage, as the proportion of EW, albumen decreased, yolk and shell slightly increased. Based on correlation coefficient analysis, irrespective of storage duration and egg weight groups, the results indicated that egg weight losses were more closely associated (P<0.05) with alteration in albumen weight than other traits. Hatchability of fertile eggs (%) of all ranges of EW were significantly decreased with longer storage time, and the heavier decreased more significant than that of the lighter one, particularly after 3 d storage. Hatchability of EW more than 40 g showed better at 2 d storage duration compared to that of 1 d storage. Hatchability of EW up to 45 g was significantly better compared to those of heavier EW. In conclusion, hatchability of hatching fertile egg of ILC can be maintained at a level higher than 75% up to 3 d storage duration, and then its decrease was markedly for the weight of the eggs heavier than 50 g.
Construction of a Class of Sharp Löwner Majorants for a Set of Symmetric Matrices

The Löwner partial order is taken into consideration in order to define Löwner majorants for a given finite set of symmetric matrices. A special class of Löwner majorants is analyzed based on two specific matrix parametrizations: a two-parametric form and a four-parametric form, which arise in the context of so-called zeroth-order bounds of the effective linear behavior in the field of solid mechanics in engineering. The condensed explicit conditions defining the convex parameter sets of Löwner majorants are derived. Examples are provided, and potential application to semidefinite programming problems is discussed. Open-source MATLAB software is provided to support the theoretical findings and for reproduction of the presented results. The results of the present work offer in combination with the theory of zeroth-order bounds of mechanics a highly efficient approach for the automated material selection for future engineering applications.
Consociate Healthcare System through Biometric Based Internet of Medical Things (BBIOMT) Approach

Internet of Medical Things (IOMT) or healthcare Internet of Thing (IOT) is a collection of medical devices and applications that connect the various healthcare systems based on IT through online computer networks. The devices are connected the output Wi-Fi allowing the M-M (machine to machine) communication through IOMT. IOMT provides various applications including remote patient monitoring (RPM), wearable fitness bands (WFB), hospital beds that are sensor equipped and many-more. IOMT allows communication of medical devices without the intervention of human. The widespread deployment of IOMT faces challenges of security, privacy, connectivity as well as compatibility. IOMT based systems suffer from various security breaches and hacking attacks. Traditional security measures of login/password do not compliment IOT based systems. So this research chapter proposes a novel Biometric Based Internet of Medical Things (BBIOMT) technology that is unique and spoof free. The BBIOMT approach eliminates shortcomings of traditional password schemes and offer a much superior authentication solution.
The effects of subacute deltamethrin exposure on rat liver: histochemical, immunohistochemical, and biochemical study

Objectives : This study aims to determine deltamethrin’s effects on early diagnosis of toxicity and liver toxicity markers in an animal model. Materials and methods : A total of 36 male rats weighing 200-220 gram were separated into four groups. Group 1 rats were given deltamethrin15 mg/kg/day, group 2 rats were given deltamethrin 30 mg/kg/day, group 3 rats were given deltamethrin 60 mg/kg/day, and group 4 rats (controlgroup) were given 0.9% sodium chloride 1 mL/kg/day for 30 days by oral gavage. Results : Deltamethrin ingestion resulted in edema, nuclear hypertrophy, and parenchymal and stromal inflammation on the histopathologicalexamination. Malondialdehyde levels increased and glutathione levels decreased when compared with the control group as the treatment doseincreased. Alanine transaminase levels increased significantly when compared with the control group. The changes correlated directly with increasingdose. Conclusion : Deltamethrin usage causes liver toxicity in a dose dependent manner on rats. This toxicity is observed both biochemically andhistopathologically. Liver biomarkers and oxidative stress parameters can effectively be used for potential toxicity monitorization.

Electro‐Optic Metasurfaces Based on Barium Titanate Nanoparticle Films

Metal‐oxides are promising candidates to substitute silicon in intra‐chip optical interconnects, as they exhibit great electric field tuning capabilities. The development of crystal ion slicing of thin films from bulk crystals and the advances over epitaxial growth have allowed the integration of metal‐oxides on a single chip. In terms of performance, they possess strong electro‐optic response over broad bandwidths across near‐infrared. However, lattice and thermal expansion coefficient mismatch limits the compatibility with available substrates and other materials, while physical hardness makes high quality nanostructures difficult to implement. Here, a novel concept of electro‐optic (EO) switching is introduced: an adjacent BaTiO3 nanoparticle film to a plasmonic metasurface provides reflection changes up to 0.15% under 4 V of control signal for modulation frequencies up to 20 MHz, in the near‐infrared. The nanoparticle films show EO coefficients (37.04 ± 25.6 pm V−1) comparable to lithium niobate crystals, are deposited uniformly over large scale and on any type of substrate, while retain optical nonlinear properties (e.g. second‐harmonic generation). Photonic nanostructures such as metasurfaces incorporated with nanoparticle films can harness the multifunctional properties of metal‐oxides such as BaTiO3 to form a new family of switchable nano‐devices across the entire visible to near‐infrared part of the spectrum.
A Senior as an Individual in the Situation of Dementia. Tom Kitwood's Person-Centred Care Model and the Philosophy of Dialogue

Abstract Seniors suffering from dementia are always exposed to a reductive approach and depersonalization due to the specificity of that disease. The subjectivity of a senior is neglected or even completely negated. What remains unnoticed is the fact that, despite their disease, a senior is still a person – with the rights and needs of a person – and not just a helpless patient. The paper presents a break that has been made in the understanding and care of seniors with dementia thanks to the work of Tom Kitwood, a British psychologist. In Kitwood’s Person-Centred Care model, a person is defined as a relational, feeling, and historical being. At the same time, being a person is only possible in the interpersonal context. Hence the author's suggestion to read Kitwood’s concept from the angle of the philosophy of dialogue, which is always an affirmation of subjectivity and an opposition to tendencies that reify human beings. In the author’s opinion, Kitwood translated the main postulates of the philosophy of dialogue into the language of psychology, gerontology and senior care by operationalizing the indicators of the well-being of a patient with dementia.
Genuine cross-frequency coupling networks in human resting-state electrophysiological recordings

Phase synchronization of neuronal oscillations in specific frequency bands coordinates anatomically distributed neuronal processing and communication. Typically, oscillations and synchronization take place concurrently in many distinct frequencies, which serve separate computational roles in cognitive functions. While within-frequency phase synchronization has been studied extensively, less is known about the mechanisms that govern neuronal processing distributed across frequencies and brain regions. Such integration of processing between frequencies could be achieved via cross-frequency coupling (CFC), either by phase-amplitude coupling (PAC) or by n:m-cross-frequency phase synchrony (CFS). So far, studies have mostly focused on local CFC in individual brain regions, whereas the presence and functional organization of CFC between brain areas have remained largely unknown. We posit that inter-areal CFC may be essential for large-scale coordination of neuronal activity and investigate here whether genuine CFC networks are present in human resting-state brain activity. To assess the functional organization of CFC networks, we identified brain-wide CFC networks at meso-scale resolution from stereo-electroencephalography (SEEG) and at macro-scale resolution from source-reconstructed magnetoencephalography (MEG) data. We developed a novel graph-theoretical method to distinguish genuine CFC from spurious CFC that may arise from non-sinusoidal signals ubiquitous in neuronal activity. We show that genuine inter-areal CFC is present in human resting-state activity in both MEG and SEEG data. Both CFS and PAC networks coupled theta and alpha oscillations with higher frequencies in large-scale networks connecting anterior and posterior brain regions. CFS and PAC networks had distinct spectral patterns and opposing distribution of low- and high frequency network hubs, implying that they constitute distinct CFC mechanisms. The strength of CFS networks was also predictive of cognitive performance in a separate neuropsychological assessment. In conclusion, these results provide evidence for inter-areal CFS and PAC being two distinct mechanisms for coupling oscillations across frequencies in large-scale brain networks.
COVID-19 and gradual adjustment in the tourism, hospitality, and related industries

In this Note, we take up the problem of post-COVID-19 gradual adjustment in the industry as well as whether and to what extent opening with limited capacity might be feasible. We find that (i) reopening gradually requiring only nonnegative profits is quite feasible but (ii) reopening requiring the same level of profit as in the pre-COVID-19 period is considerably more difficult, and seems feasible by reopening at capacity near 33%. Lower capacities would require governmental subsidies which could vary considerably from hotel to hotel.
Chromophores à absorption multiphotonique pour l'imagerie et la photothérapie dynamique : synthèse, vectorisation, greffage sur nanoparticules d'or et propriétés spectroscopiques

La therapie photodynamique (PDT) est une methode therapeutique qui permet un ciblage specifique de lesions par irradiation lumineuse localisee de photosensibilisateurs. L’utilisation d’une excitation biphotonique pourrait accroitre son interet en augmentant sa profondeur de penetration dans les tissus et en confinant son activite au point focal d’un laser. Cependant, peu de chromophores actifs a deux photons ont ete optimises pour des applications biologique, car ils possedent generalement de longues chaines conjuguees qui les rendent tres hydrophobes. Le recours a un vecteur nanometrique tel que les nanoparticules d’or, capable de se concentrer dans les tumeurs, pourrait etre une strategie interessante; d’autant plus que celles ci possedent aussi des proprietes optiques susceptibles d’influencer la spectroscopie de chromophores places a leur voisinage.
The potential thermophilic Bacilli contaminants for dairy industry

Though the biofilms of thermophilic, endospore-forming bacilli have received increasing interest in recent years, their biofilms are still unclear. In the current study, a comparative characterization of biofilm-forming patterns of totally 105 isolates and reference strains belonging to Anoxybacillus (85) and Geobacillus (20) genera were investigated. Various species belonging to these two genera have been screened for their biofilm production responses in milk, and their biofilm production patterns were also compared with their lactose and casein utilization. Thereby, this is the first report which displays strong biofilm producing behaviours of some thermophilic species in milk such as G. thermoglucosidans, A. caldiproteolyticus, A. suryakundensis, A. salavatliensis, and A. kamchatkensis subsp. asaccharedens except for well-known members like G. steraothermophilis and A. flavithermus. It was also assigned that elevated incubation temperature (65°C) had a stimulative effect on both biofilms forming capacities of Geobacillus and Anoxybacillus. Nevertheless, no direct correlation was found between biofilm formation capacity and lactose or casein catabolism characteristics. Finally, crystal violet binding assay, allowing the determination of the biofilm production amounts of microorganisms relatively in a short time, has been optimized. In this context, a methodological contribution has been provided to the literature in order to determine the possible biofilm production responses of thermophilic biofilms in the dairy industry.
