In the learning process, sensory receptors continuously send signals to the brain, then the brain to muscles and make a new signals pathway. Each time the body performs an action, millions of new synaptic connections are formed, and repetitive actions strengthen connections. So, a balanced body reuses the learned mechanism without performing any complex calculations. In contrast, the balance problem of a self-balancing robot has been solved by many different control algorithms. In this work, we propose a novel way to balance a two-wheeled self-balancing robot using bio-realistic Spiking Neural Networks (SNNs) to learn self-balancing, which is closely related to the way babies learn. To accomplish this, the gaussian shaped sensory neuronal population is connected with motor neurons through Spike-Timing-Dependent Plasticity (STDP) based synapses, further controlled with dopamine neurons. The key aspects of this approach are its bio-realistic nature and zero dependencies on data for adopting a new behavior compared to Deep Reinforcement Learning. Furthermore, this biologically-inspired mechanism can be used to improve the methodology for programming the robots to mimic Biological Intelligence.","PeriodicalId":9026,"journal":{"name":"Biointerface Research in Applied Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45864591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to create nanocomposites with the necessary mechanical properties for biomedical applications, HA was produced, and various amounts of alumina (Al2O3) were added to it. Additionally, the phase composition of the powdered nanocomposites was examined using the X-ray diffraction (XRD) technique. Crystal sizes, lattice strain, and dislocation density were all estimated as well. In order to measure the produced nanocomposite powders’ physical and elastic characteristics using the Archimedes method and ultrasonic non-destructive technique, they were then pressed and sintered at 1000 °C. The resulting information made it clear that further increases in the weight percentages of Al2O3 resulted in a 10.25, 25.64, and 33.33% reduction in crystal size. As a result of adding more Al2O3-up to 20 weight, percent-the results also showed that this properties-microhardness, compressive strength, Young’s modulus, elastic modulus, bulk modulus, shear modulus, and Poisson’s ratio-were improved by 109, 36.29, 95.5, 100.59, 104.97, 92.84 and 9.5%, respectively. Unfortunately, it increased its porosity by considerable amounts. It might be argued that the generated nanocomposites are favorable for biomedical applications.","PeriodicalId":9026,"journal":{"name":"Biointerface Research in Applied Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44190265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influences of heat sources and chemical reactions are also considered, as their applications are prevalent in several industries. The flow's constituents' governing equations are coupled with Partial differential equations (PDEs) that are converted into a dimensionless form using appropriate flow parameters. Subsequently, the finite-difference technique is used to resolve the resulting equations. The varied effects of flow parameters on the momentum, temperature, and concentration boundary layers are investigated using various graphs. The results presented in terms of non-dimensional parameters like shear stress factor, Sherwood number, and Nusselt number of fluids are tabulated for the nanofluids Ag-water and Cu-water. It is found that the augmented values of Dufour and Soret numbers enhance the fluid velocity. However, the species concentration decreases in the existence of Dufour and chemical reaction effects.","PeriodicalId":9026,"journal":{"name":"Biointerface Research in Applied Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49060448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These drugs decrease the viability of cancer cells that are guided through the HER group of receptor tyrosine kinases. We discussed that bisphosphonates straightly bind to and inhibit HER kinases. In this study for docking a nitrogen-containing bisphosphonate with human FPPS and a few other targets, the iGEMDOCK docking software has been used. Nitrogen-containing bisphosphonates (NBPs) are mostly applied for bone treatment and also for the loss of skeletal disorders. The adsorption, retention, diffusion, and release of (NBPs) in bone are controlled by their affinities to such mineral compounds. Bisphosphonates have a high affinity for Ca2+ and therefore attack bone minerals, where they are internalized by bone-resorbing osteoclasts and inhibit osteoclast function. Nitrogen-containing bisphosphonates (NBPs), including Alendronate, Zolendronate, Risedronic, Ibandronate, and Pamidronate, are functionalized as effective inhibitors of bone resorption diseases. It targets FPPS (osteoclast farnesyl pyrophosphate synthase) to inhibit protein prenylation. Generally, the strong interaction sequence is as follows Alendronate > Risedronic > Pamidronate > Zolendronate > Ibandronate, and this was because of strong electrostatic interactions between amine groups and phosphate ions.","PeriodicalId":9026,"journal":{"name":"Biointerface Research in Applied Chemistry","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45258514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
