Automatic Delivery of Machine Learning Models to User Device to Enable App Features

Many mobile apps, e.g., virtual assistants, navigation apps, video apps, etc., use various machine learning (ML) models. Different features of the app may have respective associated ML models which may often not be available locally on a user device and need explicit user action to download from a server. This disclosure describes techniques for automatic synchronization of machine learning models to a user device. With user permission, ML model(s) of an app that are not available locally or for which a new version is available are automatically downloaded when certain conditions such as are met. The conditions can include network conditions and other device-specific parameters. The overheads for determining whether the conditions are satisfied are reduced by utilizing an on-device cache and flag, which can reduce the impact on app startup latency

GENERATING A SOFTWARE DEFINED SEGMENTATION POLICY FROM STATIC/DYNAMIC ACCESS CONTROL LISTS AND ACTIVE DIRECTORY INTEGRATION

With multiple customers looking to migrate from traditional campus networks into software defined access (SDA) architectures, it is of paramount importance to enable such transitions in a simplified and automated fashion while still maintaining the current level of segmentation. To address these types of challenges, techniques are presented herein that addresses an important part of such a transition by defining a method of generating a software defined segmentation policy by integrating with an active directory (AD) and referencing the current access policies along with other known methods

Exclusion of Wormhole and Blackhole Attacks in Manets using Fuzzy Lamport Timestamp Algorithm

Security for any network is a primary concern as it is necessary to safeguard the resources that are being shared. A mobile ad-hoc network (MANET) enables the mobile devices to form a temporary network without any centralized infrastructure. MANET is vulnerable to several attacks, e.g. wormhole and blackhole attacks. Since there is increase in use of wireless communication, minimizing the intruders in wireless networks has been a high priority task. These attacks affect directly the performance of network. Eliminating such attacks in MANET is a challenging task. In this paper, a novel method that excludes the packets of wormhole and blackhole attacks in a MANET using fuzzy Lamport timestamp algorithm (FLTA) is proposed. The proposed FLTA is used to identify the order of event and to make synchronization of time clock in network device. The Lamport timestamp algorithm incorporates a fuzzy inference system to improve the performance of network. The simulated results of the proposed algorithm are compared with that of LTAWB [13] and SMTWB [12] for wormhole and blackhole attacks. It is observed that the proposed FLTA shows better performance as compared to LTAWB and SMTWB protocols in terms of throughput, end-to-end delay and packet delivery ratio

Dose response effects of carbohydrate nature of lyophilized leaf powder of Azadirachta indica on testis of albino rats

The purpose investigation is designed to investigate the effect of carbohydrate nature of lyophilized Azadirachta indica leaf powder on the histology of testis, since experimental studies shown that the chemical nature of leaf powder was studied and observed that the leaf powder was carbohydrate-rich in nature. In the present study of histomorphometric and histopathological dose dependent assessments of carbohydrate nature of lyophilized A.indica leaf powder on the testis of male wistar rats given 25, 50 and 75 mg in suspension of 1 mL Propylene Glycol, respectively/kg body weight, once daily, orally, for 24 days showed varying degrees of desquamation of seminiferous epithelial cells, degeneration of seminiferous tubules and presence of large-sized multinucleated cells as well as the spermatogenesis was arrested either at the primary spermatocytes or the spermatogonial stages. Damaged seminiferous tubules contained the abundance of vacuoles with varying size Total count, cell and nuclear diameter of spermatogonia, spermatocytes, spermatids and Leydig cells were reduced in a dose dependent manner (P ≤ 0.05). From the results obtained, it can be observed such effects on the testis are possibly due to curtailing of androgen supply within the testis or it may be a direct effect of this carbohydrate-rich nature of lyophilized A. indica leaf powder on the tissue probably due to direct or indirect gonadotrophic hormone deficiency

Isolation, Identification and Characterization of Keratin degrading microorganisms from Poultry soil and their Feather degradation Potential

Keratinolytic microorganisms have a great importance in poultry waste degradation and its bioconversion to compost or animal feed. The aim of this study was to isolate keratin degrading bacteria and fungi from poultry farm soil, and to study their ability to degrade chicken feathers. The poultry farm soil samples were added in basal medium with feathers as a source of carbon and nitrogen. Five bacterial cultures were isolated. Bacteria were grown in basal media with feathers meal and showed feather degrading capacity. Bacterial strains were identified as Aeromicrobium spp., Exiguobacter spp., Marinococcus spp. and Bacillus spp. 1 Bacillus spp 2.These bacteria showed keratinolytic enzyme activity in the cell free culture supernatants. The highest biodegradation of feathers was obtained using Aeromicrobium (KD1-72.55%), among the isolated cultures. Two fungal cultures (F1 and F2) were also isolated by Hair Bait Technique, out of which F1 showed good keratinolytic activity. The good ability of selected microorganisms to degrade feathers can be utilized for their potential biotechnological application in processing of feather waste from poultry industry

Comparative evaluation of bonding between composite relined fibre post and Conventional fibre post: an in-vitro study

Background: Fiber posts are widely used aesthetic material in restorative dentistry. These materials were introduced to overcome the inherent shortcomings of cast posts. Aim: This study aimed to evaluate and compare the pull-out bond strength of fibre posts with relining and without relining. Materials and methods: Twenty maxillary canines were extracted and underwent endodontic treatment, involving the removal of their crown portion. Post-space preparation was performed, and the appropriate post size was selected. In Group 1, ten samples were coated with a layer of composite, reinserted into the post space of the canal, and then light-cured outside the canal. The other ten samples (Group 2) were without relining. The fibre posts from both groups were cemented with RMGIC. The samples were mounted in tensile fixtures of the universal testing machine and subjected to a tensile load until the posts were debonded. The debonded samples were analysed using a stereo microscope for bond failure analysis. The obtained results were subjected to statistical analysis.   Results: The mean pull-out force in group 1 and group 2 was 72.2100±8.56420 and 61.3700±11.00611, respectively. One-way ANOVA analysis showed a significant difference in the pull-out force among the groups (P=0.043). In Group 1, 30% of the samples reported adhesive-2 failures and 70% adhesive-1&2 failures. But in Group 2, all samples were reported with adhesive-3 failures. Fisher’s Exact test displayed a significant difference in the type of bond failure between the groups (P=0.003). Conclusions: This study concluded that the coating of the fibre posts improves their tensile strength
