An investigation of feature reduction, transferability, and generalization in AWID datasets for secure Wi-Fi networks.

The widespread use of wireless networks to transfer an enormous amount of sensitive information has caused a plethora of vulnerabilities and privacy issues. The management frames, particularly authentication and association frames, are vulnerable to cyberattacks and it is a significant concern. Existing research in Wi-Fi attack detection focused on obtaining high detection accuracy while neglecting modern traffic and attack scenarios such as key reinstallation or unauthorized decryption attacks.

Effect of Substituents on Chitosan-Derived Sustainable Corrosion Inhibitors: Experimental and Computational Studies of Inhibition and Adsorption Performance.

This work involves the synthesis of two chitosan derivatives by reacting chitosan, extracted from shrimp shells in eastern Morocco, with 2-nitrobenzaldehyde via a Schiff base reaction. An amino derivative of chitosan was then produced by reducing the imine group created by sodium borohydride. We investigated the molecular weight (), crystallinity index (), and degree of deacetylation () of the isolated chitosan, among other characteristic features.

Temporal localization of upper extremity bilateral synergistic coordination using wearable accelerometers.

Background: The human upper extremity is characterized by inherent motor abundance, allowing a diverse array of tasks with agility and adaptability. Upper extremity functional limitations are a common sequela to Stroke, resulting in pronounced motor and sensory impairments in the contralesional arm. While many therapeutic interventions focus on rehabilitating the weaker arm, it is increasingly evident that it is necessary to consider bimanual coordination and motor control.

Cardiovascular disease risk assessment through sensing the circulating microbiome with perovskite quantum dots leveraging deep learning models for bacterial species selection.

Perovskite quantum dots (PQDs) are novel nanomaterials wherein perovskites are used to formulate quantum dots (QDs). The present study utilizes the excellent fluorescence quantum yields of these nanomaterials to detect 16S rRNA of circulating microbiome for risk assessment of cardiovascular diseases (CVDs). A long short-term memory (LSTM) deep learning model was used to find the association of the circulating bacterial species with CVD risk, which showed the abundance of three different bacterial species (Bauldia litoralis (BL), Hymenobacter properus (HYM), and Virgisporangium myanmarense (VIG)).

Upper extremity kinematics: development of a quantitative measure of impairment severity and dissimilarity after stroke.

Background: Strokes are a leading cause of disability worldwide, with many survivors experiencing difficulty in recovering upper extremity movement, particularly hand function and grasping ability. There is currently no objective measure of movement quality, and without it, rehabilitative interventions remain at best informed estimations of the underlying neural structures' response to produce movement. In this article, we utilize a novel modification to Procrustean distance to quantify curve dissimilarity and propose the Reach Severity and Dissimilarity Index (RSDI) as an objective measure of motor deficits.

A Novel Procrustes Analysis Method to Quantify Multi-Joint Coordination of the Upper Extremity after Stroke.

Upper extremity motor impairment affects about 80% of persons after strokes. For stroke rehabilitation, upper limb kinematic assessments have increasingly been used as primary or secondary outcome measures. There is currently no universal standardized scale for categorizing multi-joint upper extremity movement.

Optimization of predictive performance of intrusion detection system using hybrid ensemble model for secure systems.

Network intrusion is one of the main threats to organizational networks and systems. Its timely detection is a profound challenge for the security of networks and systems. The situation is even more challenging for small and medium enterprises (SMEs) of developing countries where limited resources and investment in deploying foreign security controls and development of indigenous security solutions are big hurdles.

Giant Cellulitis-Like Sweet Syndrome Masquerading As Cellulitis and Shingles: A Case Report and Literature Review.

Sweet syndrome (SS) is also known as acute febrile neutrophilic dermatoses. Clinically, SS features fever, arthralgias, and the sudden onset of an erythematous rash. The morphologies of skin lesions in SS are heterogenous, varying from papules, plaques, and nodules to hemorrhagic bullae, which sometimes makes the diagnosis of SS more challenging.

Protective Effect of Seed Extract and its Bioactive Compound Thymoquinone on Streptozotocin-induced Diabetic Rats.

Background: The lack of a substantial breakthrough in the treatment of diabetes, a global issue, has led to an ongoing quest for herbs that contain bioactive elements with hypoglycemic properties.

Objective: To investigate the potential protective effect of seeds ethanol extract and its active ingredient, thymoquinone, on streptozotocin-induced diabetic rats.

Methods: To induce diabetes, the male Wistar rats were administered an intraperitoneal injection of STZ at a dosage of 90 mg/kg body weight in 0.

Prenatally diagnosed large intrapericardial rhabdomyoma without haemodynamic compromise.

Cardiac rhabdomyoma is the most common primary cardiac tumour and is considered to be a hamartoma of developing embryonic cardiac myocytes. It is commonly seen in tuberous sclerosis. The size and location of the tumour is the surrogate determinant of the risk of haemodynamic compromise.

Natural Tyrosinase Inhibitors: Role of Herbals in the Treatment of Hyperpigmentary Disorders.

Cutaneous pigmentation plays critical role in determining the color of skin along with photo protection of skin from dreadful effects of ultraviolet radiations. Conversely, abnormal accumulation of melanin is responsible for hyper pigmentary disorders such as melasma, senile lentigines and freckles. Because of the visible nature of dermatologic diseases, they have a considerable psychosomatic effect on affected patients.

Insight into Mechanistic Action of Thymoquinone Induced Melanogenesis in Cultured Melanocytes.

Background: Melanin plays a crucial role in camouflage, social communication and protection against harmful ultraviolet radiations. Melanin is synthesized by melanocytes through melanogenesis and several intrinsic and extrinsic factors are involved during the process. Any change occuring in the normal melanogenesis process can cause severe pigmentation problems of hypopigmentation or hyperpigmentation.

Microstencil-based spatial immobilization of individual cells for single cell analysis.

Cells exhibit biologically heterogeneous phenotypes, particularly in pathogenic states. To study cell behavior at the single cell level, a variety of micropatterning techniques have been proposed that allow the spatial organization of cells with great control over cell volume, morphology, and intercellular interactions. Among these strategies, microstencil patterning has traditionally been eschewed due to fragility of membranes and lack of control over cell configurations within patterns.
