Real Time Fencing Move Classification and Detection at Touch Time during a Fencing Match

Fencingis a fast-paced sport played with swords which are Épée, Foil, and Sabre. However, such fast-pace can cause referees to make wrong decisions. Review of slow-motion camera footage in tournaments helps referees' decision-making, but it interrupts the match and may not be available for every organisation. Motivated by the need for better decision-making, analysis and availability, we introduce the first fully-automated deep learning classification and detection system for fencing body moves at the moment a touch is made. This is an important step towards creating a fencing analysis system, with player profiling and decision tools that will benefit the fencing community. The proposed architecture combines You Only Look Once version three (YOLOv3) with a ResNet-34 classifier, trained on ImageNet settings, to obtain 83.0 % test accuracy on the fencing moves. These results are exciting development in the sport, providing immediate feedback and analysis along with accessibility, hence making it a valuable tool for trainers and fencing match referees

Uplift of Anatolia

The Cenozoic history of the Anatolian Plateau is investigated using the distribution of the last Cenozoic marine strata, the ages of Neogene continental sediments and magmatic rocks, and thermochronology. In central and northern Anatolia, the youngest marine sediments are of Middle Eocene age and show that the region has been above the sea level since ca. 41 Ma. The preservation of marine Eocene sequences over large regions and widespread distribution of Neogene continental sediments point to minor erosion or subsidence, except in the Miocene core complexes, and indicate average surface uplift or subsidence rates of less than 0.05 km/Myr since 41 Ma. The Cenozoic mammal ages point to widespread continental deposition on the Anatolian Plateau from Early Miocene (ca. 22 Ma) to the present, and a similar pattern of semicontinuous magmatism has been observed in Anatolia since ca. 23 Ma. New thermochronological data from central Anatolia to west of Ankara have indicate a major exhumation phase during the Paleocene and Early Eocene, followed by minor uplift and/or subsidence. Miocene exhumation is restricted to the core complexes, such as the Kazda\u11f Massif. The Anatolian Plateau has been a land area since 41 Ma and was characterized by continental sedimentation and volcanism in the last 22 Myr. In this period, subsidence and uplift were balanced so that central Anatolia was maintained above sea level. In contrast, its southern mountainous margin, the Taurides, is free of Neogene magmatism and has undergone a fast uplift above sea level since 8 Ma (ca. 0.3 km/Myr). These differences indicate that the uplift of Anatolia cannot be ascribed to a single mechanism. Flat subduction, followed by mantle upwelling under Anatolia in the post-Middle Eocene period, maintained the region above the sea level, whereas the Late Miocene rupture of the subducting eastern Mediterranean oceanic slab have induced fast uplift of the Taurides

Biomimetic peptide-conjugated membranes for developing an artificial cornea

2022 Medical Technologies Congress, TIPTEKNO 2022 -- 31 October 2022 through 2 November 2022 -- -- 184752The corneal endothelium is composed of a single layer of specialized endothelial cells, protecting, and nourishing the inner surface of the cornea. Corneal endothelial cells do not proliferate after birth and their number decrease with age. Trauma, inflammation, or surgical intervention can cause cell loss. When damage is extensive and the density of corneal endothelial cells decreases to a critical level, it results in corneal edema and vision loss. Besides them, when corneal endothelium has irreversible damage, the only treatment way is corneal transplantation. But there are some drawbacks such as finding donors, immune reactions, and the number of patients waiting on the transplantation lists for years. Tissue engineering approaches can provide promising alternatives for the regeneration of corneal endothelium tissue. Peptides can be used to modify and functionalize the scaffolds, allowing for the production of bioactive and biomimetic surfaces. Peptide-modified scaffold surfaces might direct and enhance the behaviors of cells. In this study, the aim was to functionalize the polycaprolactone (PCL) membranes with tissue-specific peptides and to characterize the peptide-conjugated membranes by Fourier-Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and X-ray Photoelectron Spectroscopy (XPS) analysis. The synthesized peptides were successfully conjugated on the PCL biomembranes. © 2022 IEEE.ACKNOWLEDGMENT The authors thank to the Scientific and Technological Research Council of Turkey (TUBITAK) (1003 Project numbers: 218S991, 219S989, and 318S275).Türkiye Bilimsel ve Teknolojik Araştırma Kurumu, TÜBİTAK: 218S991, 219S989, 318S27

Fats’ love–hate relationships: a molecular dynamics simulation and hands-on experiment outreach activity to introduce the amphiphilic nature and biological functions of lipids to young students and the general public

Lipids are fundamental components of biological organisms and have important applications in the pharmaceutical, food, and cosmetics industries. Thus, it is important that young students and the general public properly understand the basic properties of lipids and how these relate to their biological and industrial roles. Here, we use molecular dynamics computer simulations and a simple, safe, and inexpensive popular hands-on activity, to communicate to participants why and how lipid molecules play a fundamental role in all living organisms and in our bodies. The activity is called “Fats’ Love–Hate Relationships”, to highlight how the different parts of amphiphilic lipids interact with water. This “love–hate relationship” is vital to the biological functions of lipids and drives the formation of lipid structures that can be visualized at molecular scale with the computer simulations. The participants were encouraged to investigate the interactions between milk lipids and soap surfactants, creating beautiful complex artwork that they could then take home. The hands-on activity was accompanied by a video of a molecular simulation that illustrates milk–soap interactions at a molecular scale and helps to explain how the amphiphilicity of lipids creates the beautiful artwork at a molecular level. The outreach activity has been performed in science festivals and in classrooms and has been well received by participants of all ages with multiple learner comprehension levels (primary and secondary school students and the general public). By combining molecular simulation, explanations of the amphiphilic structure of the lipids, and an engaging hands-on activity, we explained how lipids interact with water and surfactants and inspired discussions on the link between the structure of the lipids and their biological function, namely, their structural and protective roles as a key component of cell membranes
