Biometric Watermarking Schemes Based on QR Decomposition and Schur Decompositon in RIDWT Domain
Authors: Altay Seyma Yucel , Ulutas Guzin 
Published: January 2023

Abstract
In this paper, two new methods are proposed to hide a biometric-based digital watermark generated from an iris image into a color image to resolve ownership conflicts. One of them is the QR decomposition-based approach in the redistributed invariant discrete wavelet transform (RIDWT) domain, and the other is the Schur decomposition-based approach in the RIDWT domain. After the Y channel of the color image in YCbCr space is decomposed by RIDWT, the lowest frequency sub-band is divided into non-overlapping blocks. Blocks with a lower standard deviation are selected to embed each bit of the watermark created from the iris image into a block. Watermarking of selected blocks is performed with QR decomposition in the first approach and Schur decomposition in the second approach. The firefly algorithm is used to balance the robustness and perceptual transparency in hiding the watermark. Experimental results are evaluated in terms of robustness and imperceptibility to prove the effectiveness of the proposed systems. In addition, validation performances are analyzed based on false rejection rate, false acceptance rate and equal error rate. The results show that both methods have high perceptual quality and robustness, and also a very low error rate in ownership verification.

Published: January 2023

Abstract
Cardiovascular disease is the primary reason of death within a short period because of a sudden blockage in blood vessels. Therefore, early diagnosis and treatments are necessary to reduce the disease severity. In this study, Image augmentation concepts are used for balancing the ECG images dataset classes. The balanced dataset contains 6322 images from five different classes are Normal, Abnormal Heartbeat, Myocardial Infraction (MI), Previous History of MI, and Covid-19 ECG images. The pre-trained models VGG-16, ResNet-50, and DenseNet-161 are used to train on ECG balanced dataset. The use of hyper-parameters will increase the accuracy of classifying cardiovascular disorders which includes learning rate, optimizer, and dropout. The mentioned pre-trained models reported the highest accuracy at learning rate = 0.00001 and dropout=0.3 with Adam optimizer. DenseNet model achieved 93.33% accuracy, 94.23% precision, 93.33% recall, and 93.30% F1-Score, which is higher in performance compared to ResNet-50 and VGG-16 pre-trained models.

Abstract
The soybean meal replacement with corn meal and chestnut meal was evaluated on growth performance, feed utilization efficiencies, nutrient digestibility, organosomatic and body composition of Oreochromis niloticus fingerlings. Seven experimental diets were categorized into various groups containing 0 (control), 5, 15, and 25% of corn and chestnut meals respectively. The experimental diets were given to triplicate groups of Nile tilapia (7.31 ± 0.12g) at a rate of 3% of body weight for 12 weeks. Similar growth performance and feed conversion ratio was observed in control group and groups fed corn gluten meal and chestnut meal based diets. There was no significant difference (P ˃0.05) in feed efficiency ratio and protein efficiency ratio in control group and treatment groups. The hepatosomatic index values were not significantly different (P ˃0.05) in control group and other treatment groups. The viscerosomatic index values differed significantly (P ˂0.05) among experimental groups. The highest value was obtained in group fed diet containing 5% corn meal and lowest for group fed diet containing 15% chestnut meal. The substitution of soybean meal had no significant impact (P ˂0.05) on moisture, protein and fat contents in fish whole body composition. The apparent digestibility of protein, fat, fiber, carbohydrates and ash were significantly different (P ˂0.05) for groups fed control, corn meal and chestnut meal based diets. The ADC value for protein was highest in group fed 5% chestnut containing diet and lowest value was exhibited by group fed 15% chestnut meal diet. The ADC values of crude fiber and crude fat were highest for diets containing 15% chestnut and 15% corn respectively and lowest in control group. The apparent digestibility of crude ash was highest for group fed diet containing 15% corn and lowest for diet containing 5% chestnut meal. It can be concluded that up to 25% of corn and chestnut meal can be used to substitute soybean meal in diet for Nile tilapia fingerlings on basis of weight gain without any negative effect on growth and feed utilization efficiency.

Published: January 2023

Abstract
The current study looked into continuous two-dimensional Jeffery fluid flow and heat transfer with radiation and heat source effects past linearly stretched sheet under suction/injection conditions. I have investigated the effects of the magnetic dipole on two different thermal processes: prescribed surface temperature (PST) and prescribed heat flow (PHF). The governing non-linear PDEs are converted into a system of coupled non-linear ODEs using the appropriate transformations, and the numerical solutions are carried out using the bvp4c solver included in the MATLAB package. The effects of the parameters investigated—ferromagnetic interaction parameter (\(\beta\)), Deborah number (\(\gamma\)), radiation parameter (R), heat sources parameter (Q), Prandtl number (Pr), suction/injection parameter (S), ratio of relaxation to retardation times (\({\lambda _2}\)), and Grashof number (Gr)—on velocity and temperature profiles—are graphically depicted in the figures.

Authors: Ramdev Mandeep Singh , Bajaj Rohit , Pawar Lokesh 
Published: January 2023

Abstract
The most complex node in LTE-A is the base station referred to as eNodeB. eNodeB consists of two major elements Remote Radio Head (RRH) which consists of antennas and the Base Band Unit (BBU) which comprises of digital modules that processes all signals transmitted and received over the air interface and acts as the interface to the core network over a high-speed backhaul connection. The Remote Radio Head transforms the digital base-band signals of Base Band Unit into RF signals and improves power to transmit to the UE by means of protocol-specific processing. There is forever need for efficient and adaptive algorithm which can handle the load of peak time as well as non-peak time. An efficient scheduling algorithm to adjust and manage these network changes without degrading network performance and network quality is required at the Remote Radio Head which also remains the least explored component of eNodeB. Novel Improved Proportional Fair (iPF) Algorithm based approach has been proposed in this study made LTE based networks more efficient and fast in terms of parameters such as Peak Throughput, Average Throughput, Edge UE Throughput, Average Cell Throughput, Average UE Throughput, Spectral Efficiency, Fairness Index and RI Distribution.

Authors: Bernaards Coen A. , Fischer Kathrin I. , Rylands Angela J. , Gater Adam , Tolley Chloe , Zarit Steven H. , Lansdall Claire J. 
Published: January 2023

Background:
Caring for an individual with Alzheimer’s disease (AD) is an allencompassing
challenge that affects daily life. Assessment of the care partner experience is needed to
support the development and evaluation of successful interventions for people with AD and their care
partners. We developed the 27-item Zarit Caregiver Interview for Alzheimer’s Disease (ZCI-AD-27)
to assess the impact of informal caregiving in the context of AD.

Objective:
We assessed the psychometric validity of the ZCI-AD-27 in a population of care partners
for individuals with moderate AD, and established thresholds for meaningful score change.

Methods:
Secondary data were obtained from informal care partners of participants in a clinical trial
(NCT01677754). Psychometric analyses were conducted to assess validity, reliability, and responsiveness
of the ZCI-AD-27. Anchor-based and distribution-based methods were performed to determine
clinically meaningful score change.

Results:
The ZCI-AD-27 had a 12-domain factor structure, including a second-order domain termed
Humanistic impact that included four key domains (Physical, Emotional, Social, and Daily life) as
confirmed by confirmatory factor analysis with the adequate fit. Internal consistency (Cronbach’s alpha
ranging from 0.66 to 0.93 for domains), convergent validity, and discriminant validity indicated
the good performance of the ZCI-AD-27. Known-groups validity analyses showed a greater impact on
care partners with increasing disease severity. Responsiveness results demonstrated that the ZCI-AD-
27 is sensitive to change over time and meaningful change analyses indicated a range of meaningful
score changes in this population.

Conclusion:
The ZCI-AD-27 is a comprehensive, psychometrically valid measure to assess the impact
of caring for individuals with moderate AD.
Bioactive Heterocycles: Green Synthesis and its Anti-Alzheimer Activity
Authors: Fathima Afridha Mohamed Sulthan Hasan , Aazath Kathar , Roopan Selvaraj Mohana , Anto Simplica Sagayaraj Jane 
Published: January 2023

Abstract:
The wide pharmaceutical activity of the bioactive heterocycles, which include nitrogen,
oxygen, and sulphur and comprise five- and six-membered rings, has drawn the attention of medicinal
chemists for several years. The therapeutic potential of bioactive heterocycles for a variety of disorders
lies in their medicinal effects. The most prominent of them is Alzheimer's disease (AD), a
neurodegenerative disorder that impairs memory and causes other psychiatric problems. Globally, there
are around 54 million cases, and by 2050, that number is predicted to rise by 131 million. So far,
donepezil, galantamine, and rivastigmine have indeed received FDA approval for use in the treatment of
AD. In this regard, the pharmacophoric properties of heterocycle molecules are equivalent to those of
galantamine mimics. Therefore, it is beneficial to create novel compounds containing these moieties and
test their ability to inhibit acetyl and butyl cholinesterase. Diverse heterocyclic scaffolds may now have
therapeutic potential for Alzheimer's disease. Recently, greener and more expeditious synthesis of
bioactive heterocycles has drawn much attention because of the utilisation of environmentally benign
protocols, thereby diminishing the usage of hazardous chemicals. In this review, we discuss the most
pertinent findings about the "green" synthesis of heterocycles and their possible anti-activity against
Alzheimer's.
Study on the Properties of Iron-based Alloys 17-4PH Powder
Manufactured by Laser Additive Manufacturing
Authors: Huang Lei , Chen Xizhang , Konovalov Sergey , Su Chuanchu , Pan Xiaoming , Panchenko Irina 
Published: January 2023

Background:
Laser additive manufacturing has been used for surface repair and remanufacturing
due to fast laser processing speed, high energy density, and dense microstructure.
However, the properties of coating samples produced by laser additive manufacturing of ironbased
alloys vary considerably, resulting in a large amount of data that needs to be accumulated
and analyzed.

Methods:
The coating properties of iron-based alloy powders manufactured by laser cladding are
studied. The optimal process parameters of the laser cladding are determined by exploring and
comparing the macroscopic appearance, hardness, and conductivity of the junction of the cladding.

Results:
From the macroscopic appearance, when the ratio of the height to the width of the cladding
layer is 3.615, the surface of the cladding layer has a smooth surface and is closely combined
with the substrate.

Conclusions:
The hardness of the cladding layer is found to increase significantly, with an average
hardness of 663 HV. Besides, it is found that the blackhead's hole causes the conductivity
change. The ratio of the largest hole area to the smallest hole area is 8.29 times, and the depth ratio
is 1.91 times, but the average resistance ratio is about 1.6 times.

Como ser um bom aluno? Dos modelos de escola aos pontos de vista das crianças
Authors: Melo Benedita 
Published: January 2023

Resumo
A apologia da performatividade e da excelência, resultante dos novos modos de regulação dos sistemas educativos, parece estar a penetrar em todos os níveis de escolaridade. Centrado na análise do ofício de aluno do 1.º ciclo, e tendo por base a hipótese de que estará em curso uma reconfiguração do modelo da escola primária assente na performatividade-competitividade, este texto analisa as perspetivas que crianças, oriundas de contextos geográficos, escolares e socioeconómicos distintos, possuem sobre o que é ser um bom aluno. A pesquisa teve por base a análise de conteúdo de entrevistas semidiretivas realizadas a 61 crianças do 3.º ano de escolaridade, em 2017/18. Os pontos de vista das crianças evidenciam duas dimensões essenciais das práticas escolares: a dimensão do poder e a dimensão cognitiva. As suas referências à ordem escolar deixam perceber como a estrutura do modelo de escola tradicional-industrial subsiste na atualidade. No entanto, é a componente das aprendizagens a que é mais valorizada nos seus discursos. As condições por elas enunciadas para participarem nos processos de aprendizagem dão conta de dois tipos de conceções sobre a excelência escolar. Uma primeira que enaltece os dons individuais, nomeadamente a inteligência, presente sobretudo entre as crianças com uma proveniência social menos escolarizada e menor desempenho escolar. Uma segunda conceção, próxima do modelo escolar performativo-competitivo, surge ancorada no trabalho, esforço, dedicação e superação individual, e está sobretudo presente nas crianças oriundas de famílias mais escolarizadas, com muito bom aproveitamento escolar.
