Artificial intelligence(AI)has recently been developing rapidly in image processing and generation.AI is not only starting to take over repetitive and tedious tasks but is also involved in creative activities.Drawing is one of the areas with the greatest potential for collaboration between humans and AI.It is an important approach to express various information,but due to the lack of appropriate knowledge and skills,ordinary people without long-time training are unable to draw freely.Although there have been various attempts at human-AI collaboration in drawing,it is difficult for researchers to consider the wide variety of specific problems and develop univer-sal methods due to the openness,improvisation,and individuality of drawing.In this paper,we first analysed the contents of drawing and the general creation process in detail.Second,we have described a mechanism for using AI to enable people to regain the freedom of drawing collaboratively.Finally,we have developed a framework that describes methods for analysing specific problems and quickly finding solutions by building connections between the influencing factors in drawing,the demands of humans,and possible implementa-tion options.The framework also reveals a broad scope of possibilities for applying AI to support people in drawing.

The duality of cultural and creative industry can maintain the independence of creative birth and management as well as taking into account of the artistic and marketability of creativity.Income distribution contracts that link the design process to the commercial value of creative ideas can solve the problem of quantitative incentives for creative subjects.At the same time,it can encourage creative subjects to complete commercial and artistic design activities.The principal-agent relationship between the upstream and downstream of the industrial chain is utilized to stimulate the creation of creative ideas in line with market conditions,so as to solve the problem of duality reconciliation of cultural and creative industries.Through the design of the cultural creative industry chain dual task creative incentive contract,in the process of encouraging creative design subjects to complete the design of the work to give consideration to the coordination of duality.By analyzing the influences of design capability,risk,cost coefficient and binary correlation on the optimal investment level and the optimal risk sharing level of creative subjects in two types of design activities,the input transfer caused by the variation of the above conditions is further discussed.

Ammonium dinitramide [NH4 N(NO_2)2, ADN] is considered as a possible replacement for ammonium perchlorate(AP) in nearly all kind of solid rocket propulsions in the coming future. The reason to use ADN instead of AP in solid rocket propulsion is because of its harmless combustion products, along with its capacity to generate high specific impulse(Isp). ADN is fairly a new member in the solid oxidizer community and is considered under green energetic material(GEM). Application and feasible utilization of ADN as an oxidizer for composite solid propellants(CSP's) requires complete knowledge of its thermal decomposition processes along with its combustion behavior. A detailed overview on the physical and chemical properties, thermal decomposition, and combustion behavior of ADN and ADN based propellants has been discussed in this paper. Catalytic effect on thermal decomposition, combustion wave structure, and burning rate of ADN is also discussed.

Artificial entities,such as virtual agents,have become more pervasive.Their long-term presence among humans requires the virtual agent’s ability to express appropriate emotions to elicit the necessary empathy from the users.Affective empathy involves behavioral mimicry,a synchronized co-movement between dyadic pairs.However,the characteristics of such synchrony between humans and virtual agents remain unclear in empathic interactions.Our study evaluates the participant’s behavioral synchronization when a virtual agent exhibits an emotional expression congruent with the emotional context through facial expressions,behavioral gestures,and voice.Participants viewed an emotion-eliciting video stimulus(negative or positive)with a virtual agent.The participants then conversed with the virtual agent about the video,such as how the participant felt about the content.The virtual agent expressed emotions congruent with the video or neutral emotion during the dialog.The participants’facial expressions,such as the facial expressive intensity and facial muscle movement,were measured during the dialog using a camera.The results showed the participants’significant behavioral synchronization(i.e.,cosine similarity≥.05)in both the negative and positive emotion conditions,evident in the participant’s facial mimicry with the virtual agent.Additionally,the participants’facial expressions,both movement and intensity,were significantly stronger in the emotional virtual agent than in the neutral virtual agent.In particular,we found that the facial muscle intensity of AU45(Blink)is an effective index to assess the participant’s synchronization that differs by the individual’s empathic capability(low,mid,high).Based on the results,we suggest an appraisal criterion to provide empirical conditions to validate empathic interaction based on the facial expression measures.

In this paper, an analytical scientific approach is presented for the design and analysis of an air-turbine-driven paint spray spindle, and it is used to improve further the design concept of the existing spindle applied in automotive coating and paint spraying applications. The current spindle on the market can operate at a maximum speed of 100,000 rpm and features a maximum bell size of 70 mm diameter. Given the increasing demands for high automotive coating/painting quality and productivity in assembly, the design and development of a paint spray spindle with a speed of 145,000 rpm or higher is needed. Computational fluid dynamics(CFD)-based simulation is applied in the approach. Accordingly, CFD simulation-based design and analysis are undertaken, covering the characteristic factors of velocity, pressure of the air supply, rotational speed of the air-turbine, and torque and force reaction on the turbine blades. Furthermore, the turbine blade geometric shape is investigated through the simulations. Three geometrical concepts have been investigated against the original model. The results on Concept_03 verified the higher angular velocity speeds against the theoretical model. The pressure and velocity effects in the blades have been investigated. The results show that the pressure and velocity of the air supply driving the turbine are critical factors influencing the stability of turbine spinning. The results also demonstrate that the force acting on the blades is at the highest level when the adjacent face changes from a straight surface into a curve. Finally, changing the geometrical shape in the turbine likely increases the tangential air pressure at the blades surface and relatively increases the magnitude of the lateral torque and force in the spindle. Notwithstanding this condition, the analytical values surpass the theoretical target values.

Remdesivir(RDV) is the only US Food and Drug Administration(FDA)-approved drug for treating COVID-19.However,RDV can only be given by intravenous route,and there is a pressing medical need for oral antivirals.Significant evidence suggests that the role of the parent nucleoside GS-441524 in the clinical outcomes of RDV could be largely underestimated.We performed an in vitro and in vivo drug metabolism and pharmacokinetics(DMPK) assessment to examine the potential of RDV,and particularly GS-441524,as oral drugs.In our in vitro assessments,RDV exhibited prohibitively low stability in human liver microsomes(HLMs,t1/2=-1 min),with the primary CYP-mediated metabolism being the mono-oxidation likely on the phosphoramidate moiety.This observation is poorly aligned with any potential oral use of RDV,though in the presence of cobicistat,the microsomal stability was drastically boosted to the level observed without enzyme cofactor NADPH.Conversely,GS-441524 showed excellent metabolic stability in human plasma and HLMs.In further in vivo studies in CD-1 mice,GS-441524 displayed a favorable oral bioavailability of 57%.Importantly,GS-441524 produced adequate drug exposure in the mice plasma and lung,and was effectively converted to the active triphosphate,suggesting that it could be a promising oral antiviral drug for treating COVID-19.

Integrated sensing and communication(ISAC)is regarded as a recent advanced technology,which is expected to realize the dual functions of sensing and communication simultaneously in one system.Nevertheless,it still faces the challenges of the information security and transmission robustness caused by the openness of wireless channel,especially under antagonistic environment.Hence,this article develops a generalized framework,named cognitive joint jamming,sensing and communication(cognitive J2SAC),to empower the current sensing/communication/jamming system with a“brain”for realizing precise sensing,reliable communication and effective jamming under antagonistic environment.Three kinds of gains can be captured by cognitive J2SAC,including integrated gain,cooperative gain and cognitive gain.Moreover,we highlight the enabling mechanism among jamming,sensing,and communication,as well as illustrating several typical use cases of cognitive J2SAC.Furthermore,several key enabled technologies are analyzed and a typical sensing enhance integrated communication and jamming case study is discussed to verify the effectiveness of the proposed method.Last but not the least,the future directions are listed before concluding this article.Integrated sensing and communication(ISAC)is regarded as a recent advanced technology,which is expected to realize the dual functions of sensing and communication simultaneously in one system.Nevertheless,it still faces the challenges of the information security and transmission robustness caused by the openness of wireless channel,especially under antagonistic environment.Hence,this article develops a generalized framework,named cognitive joint jamming,sensing and communication(cognitive J2SAC),to empower the current sensing/communication/jamming system with a“brain”for realizing precise sensing,reliable communication and effective jamming under antagonistic environment.Three kinds of gains can be captured by cognitive J2SAC,including integrated gain,cooperative gain and cognitive gain.Moreover,we
