Recent work introduced the notion of 'emotional challenge' promising for understanding more unique and diverse player experiences (PX). Although emotional challenge has immediately attracted HCI researchers' attention, concept not been experimentally explored, especially in virtual reality (VR), one latest gaming environments. We conducted two experiments to investigate how affects PX when separately from or jointly with conventional VR PC conditions. found that relatively exclusive induced...

To improve the survivability of probiotics, Lactobacillus plantarum was microencapsulated using pufferfish skin gelatin (PSG)-based wall materials by spray-drying. This work investigated protective effect three different pH-dependent proteins (sodium caseinate (SC), soy protein isolate (SPI), and whey (WPI)) combined with PSG on L. plantarum. The experimental results spray-drying an inlet temperature 120 °C outlet 80 °C, storage at 4 for 6 months, simulated digestion, turbidity indicated...

滇西地区位于东特提斯构造域东段,经历了特提斯构造域复杂的地质演化过程,导致该地区发育大量与稀有金属成矿相关的花岗伟晶岩脉,具有极好的花岗伟晶岩型稀有金属成矿地质条件。区域地质调查评价和地球化学填图显示滇西地区具备形成锂、铍、铌、钽等稀有金属矿产资源的良好潜力。本文以滇西地区黄连沟、黄草坝、那俄、杞木寨、麻栗脑、禾波、黑妈等含稀有金属矿化的花岗伟晶岩为研究对象,通过铌钽铁矿、独居石、锆石等LA-ICP-MS U-Pb定年手段,对这些花岗伟晶岩型稀有金属矿床/点开展成矿/成岩年代学研究。结果显示滇西花岗伟晶岩型稀有金属矿床主要形成于晚白垩世-始新世(ca.70~40Ma),与中国其他地区花岗伟晶岩型稀有金属矿床主要形成于早古生代和中生代时期有显著的差异。本文年龄结果表明滇西地区存在多阶段花岗伟晶岩型稀有金属成矿事件,可能与区域新特提斯构造-岩浆活动关系密切。这些年龄为探讨滇西花岗伟晶岩型稀有金属成矿规律,有效指导区域找矿勘探部署和建立该地区伟晶岩型稀有金属矿床成矿模型奠定了理论基础。

Virtual sculpture is a modeling technique for computer graphics based on the notion of sculpting solid material with tools. Currently, most interactive mainly focused vision-based sensory channel. With visual feedback alone virtual cannot simulate realistic operations in physical world. The sense touch, combination our kinesthetic sense, capable adding new modality to sculpture, especially presenting complex geometry & properties. In this paper, we propose haptic (VHS) system volume space,...

The issue of a low minority class identification rate caused by data imbalance in anomaly detection tasks is addressed the proposal GAN-SR-based intrusion model for industrial control systems. First, to correct classes dataset, generative adversarial network (GAN) processes dataset reconstruct new training samples accordingly. Second, high-dimensional feature extraction completed using stacked asymmetric depth self-encoder address issues reconstruction error and lengthy times. After that,...

Identify novel tyrosinase inhibitory peptides from sea cucumber (Apostichopus japonicus) collagen using in silico methods and elucidate the molecular interaction mechanism.Tyrosinase is a key enzyme melanin biosynthesis pathway, to restrain production reduce appearance of associated skin diseases, inhibition activity one most effective methods.The Apostichopus japonicus, which consists 3,700 amino acid residues, was obtained National Center for Biotechnology Information (NCBI) as accession...

The Hongnipo deposit, a newly discovered large copper deposit in the Kangdian belt, SW China, is hosted Paleoproterozoic Hekou Group. This contains ~4200 Mt of Cu ores, with an average grade 1.42 wt.% Cu. Orebodies occur mainly as stratiform, stratoid and lenticular forms. Mineralization consists predominantly high vein-type ores low laminated ores. Field relationships indicate mineralization crosscuts host rocks, indicating that there were at least two events during formation deposit....

Abstract The southern Great Xing'an Range is the most critical Sn‐polymetallic metallogenic belt in northeast China. However, tectonic setting of Early Cretaceous magmatic‐metallogenic “flare‐up” event remains uncertain. This paper presents an integrated study on occurrence, petrology, zircon U‐Pb ages, whole‐rock geochemistry, and situ Hf isotopes for Wenduerchagan granites Xi Ujimqin Banner, central‐eastern Inner Mongolia. These consist primarily granite porphyry (with ages 137 ± 1 Ma 138...
