AdaptorPro:A Deep Learning Approach for Accurate Identification of Adaptor Proteins
Adaptor proteins, pivotal in signal transduction ,consist of diverse modular domains, each exhibiting unique binding activities, forming complexes with intracellular signaling molecules. Implications of adaptor proteins in various human diseases underscore the need for accurate predictive models. In addressing this, we compiled a dataset featuring 2,484 positive (G0:0060090) and 15,495 negative (G0:0140110) results. Removal of highly similar sequences using the bio-conda CDHIT API yielded 1429 non-redundant clustered Adaptor proteins for G0:0060090. Similarly, G0:0140110 resulted in 8076 non-redundant clustered Adaptor proteins. Employing a 5-step rule predictor based on statistical moments and PseAAC for feature extraction, we split the dataset into 80% training and 20% testing. Our approach, currently employing known neutral models, advances bioinformatics efforts in anticipating the actions of adaptor proteins, holding promise for unravelingintricate cellular signaling mechanisms
A Taxonomy for Supporting Industry- Academia Communication in Software Quality
Software quality is one of the most important components of software development. Software quality attracts the user\u27s attention and produces reliable and error-free software. Poor approach strategies lead to less effective outcomes and a higher likelihood of failure. The gap between software quality research and practice is one of the main problems with software quality. The difference between the way software quality research is communicated and the way industry concerns related to software quality is the actual gap.software industries are unaware about rapid technological change, complexities of Modern software systems, security concerns, skill shortage impact on software quality, to overcome theses problems and gaps. Taxonomy is proposed to enhance industry-academia collaboration by facilitating better communication between software quality research and practice. Some of the best quality standards are outlined and authorized in this paper that yields the greatest out-comes. A methodical and goal-oriented strategy is used to develop the proposed taxonomy, with the help of literature review, blogs, articles, and interviews with researchers and practitioners. Twenty distinct questions regarding team co-ordination, dispersion, culture, behaviors and attitudes, experience, and other topics are included in the questionnaire. The taxonomy is evaluated through online survey by implementing it in an industry-academia collaboration project. Researchers and practitioners could use the proposed taxonomy to classify and identify quality concerns or obstacles

A Novel Relaxed Dynamic Local Ternary Pattern Texture Descriptor for Face Anti-Spoofing
Now a day’s biometric authorization is utilized for security applications like identification and recognition. There are many biometric traits like fingerprint, face, iris, voice etc. The motivation behind the use of biometric systems is that remembering pin and password is quite difficult for a person and also it can be easily stolen. Unlike pin and password based system, biometric system cannot easily be stolen and forgotten because of its unique characteristics. In Biometric systems, the face based biometric system is mostly used for security purpose to identify the users according to the uniqueness of their features and easy availability. There are still many challenges that faced by face biometric security systems, such as some culprits make fake faces made from different material e.g. paper, digital electronic devices or 3D masks. The system can be easily be spoofed and give access to unauthorized persons. Due to this security breach an identification system should be designed that verifies whether the users are genuine or fake. In this paper, a novel Texture descriptor is proposed named as Relaxed Dynamic Local Ternary Pattern (RDLTP) for texture analysis in the field of anti-spoofing. The proposed texture descriptor is analyzed on publically available datasets to differentiate that either the input is from genuine face or spoofed face via Support Vector Machine (SVM) Classifier. The obtained outcomes from the proposed RDLTP Descriptor showed improved accuracy and performed well as compared to the most popular texture descriptor from the literature i.e. Local Binary Pattern (LBP) and Local Ternary Pattern (LTP).

Hybrid FNN-DNN Approach for Early Detection of Cardiac Arrhythmia: A Novel Framework for Enhanced Diagnosis
This work introduces a relatively new hybrid approach to detect arrhythmias noninvasively at the early stages by combining Feedforward Neural Networks (FNN) with Deep Neural Networks (DNN). It is oriented towards the critical area of detecting minute anomalies in the heart rhythm impetuses which are essential to enable prompt management and better results. The foreseen framework tries to solve the gaps in the existing diagnostic methods by using deep learning techniques especially in understanding sequential patterns in medical information. Detection at a speed and on a proper level is a lifesaving key because cardiac arrhythmias can cause serious problems like the stroke and the heart failure. We should make sure that there are more sensitive techniques (other than the traditional ECGs) as the conventional methods (such as ECGs) suffer from some restrictions which may be subjective and also can achieve low accuracy. The distinct attributes of subtle pattern uncovering and making the easy yet precise diagnoses of the Hybrid FNN-DNN model places it a SMART choice for the future. The results demonstrate the need to detect heart rhythm disorders in the early stage as they can have a great influence in terms of patient health and the health sector spending on serious arrhythmia consequences like heart failure or stroke. The effectiveness of the hybrid model in separation between persons with heart disease and the rest is measured by a composite assessment that employs many measures e.g., accuracy, precision, recall, F1-score and AUC-ROC curve analysis. The empirical result highlights that the hybrid model has achieved the same accuracy as both FNN model with 84.8% and DNN model which are 84.8% as well. Another point that the article alludes to is that in the medical environment, deep learning models should be interpretable and provide the therapeutic information needed. Therefore, in order to recognize that the created model coincides with clinical practices and strives to improve patients\u27 care, collaborative efforts with domain experts are carried out. However, the hybrid FNN-DNN strategy is just the beginning for the developing cardiovascular management and treatment field as it provides a good path to progressing with getting better detection and early diagnosis of cardiac arrhythmias. It is necessary to carry out more research and proof-of-concept validation of the proposed tool for a wider population
