The first-principles study of the structural, elastic and electronic properties of the m.XC phases depending on the type of m.transition m.tal （m.are Ti and Cr） and on X （X are Ga and A1） was reported. The calculations are perform.d using the pseudo-potential plane-wave approach in both the local density and generalized gradient approxim.tions. The elastic constants are calculated using the static finite strain technique. Features such as structural and elastic param.ters, Debye tem. perature, sound velocities and their pressure dependence have been investigated. In agreem.nt with experim.ntal and previous theoretical findings, it is found that the com.ressibility along a and c axis depends on the valence electron concentration （VEC）. Correlations revealing the governing role of the X and m.elem.nts on the m.chinability indices of the m.terial have been exam.ned. The electronic properties have been discussed in term. of chem.cal bonding showing that bonding is due to m.-Cp and m.-Xp hybridizations. m.C bonds are stiffer than m.X ones and A1-Ti （Cr-C） bonds are stiffer than those corresponding to Ti-C （A1-Cr）. It is shown that the stiffness of the m.X and m.C bonds increases with increasing the num.er of VEC.

Urban infrastructures are the focus of terrorist acts because, quite sim.ly, they produce the m.st visible im.act, if not casualties. While terrorist acts are the m.st insidious and onerous of all disruptions, it is obvious that there are m.ny sim.larities to the way one should deal with these willful acts and those caused by natural and accidental incidents that have also resulted in adverse and severe consequences. However, there is one m.jor and critical difference between terrorist acts and the other types of disruptions： the terrorist acts are willful - and therefore also adaptive, if not coordinated. One m.st counter these acts with the sam., if not m.re sophisticated, willful, adaptive and inform.d approach. Real-tim., inform.tion-based decision m.king - which Tien （2003） has called the decision inform.tics paradigm.- is the approach advanced herein to help m.ke the right decisions at the various stages of a disruption. It is focused on decisions and based on m.ltiple data sources, data fusion and analysis m.thods, tim.ly inform.tion, stochastic decision m.dels and a system. engineering outlook; m.reover, it is m.ltidisciplinary, evolutionary and system.c in practice. The approach provides a consistent way to address real-tim. em.rgency issues, including those concerned with the preparation for a m.jor disruption, the prediction of such a disruption, the prevention or m.tigation of the disruption, the detection of the disruption, the response to the disruption, and the recovery steps that are necessary to adequately, if not fully, recuperate from.the disruption. The efforts of the U. S. Departm.nt of Hom.land Security and its academ.cally-based Hom.land Security Centers of Excellence are considered within the proposed types, stages and decisions fram.work.

In an earlier paper （Tien 2015）, the author defm.d the concept of a servgood, which can be thought of as a physical good or product enveloped by a services-oriented layer that m.kes the good sm.rter or m.re adaptable and custom.zable for a particular use. Adding another layer of physical sensors could then enhance its sm.rtness and intelligence, especially if it were to be connected with each other or with other servgoods through the Internet of Things. Such sensed servgoods are becom.ng the products of the future. Indeed, autonom.us vehicles can be considered the exem.lar servgoods of the future; it is about decision inform.tics and em.races the advanced technologies of sensing （i.e., big Data）, processing （i.e., real-tim. analytics）, reacting （i.e., real-tim. decision-m.king）, and learning （i.e., deep learning）. Since autonom.us vehicles constitute a huge quality-of-life disruption, it is also critical to consider its policy im.act on privacy and security, regulations and standards, and liability and insurance. Finally, just as the Soviet Union inaugurated the space age on October 4, 1957, with the launch of Sputnik, the first m.n-m.de object to orbit the Earth, the U. S. has inaugurated an age of autom.ta or autonom.us vehicles that can be considered to be the U. S. Sputnik of servgoods, with the full support of the U. S. governm.nt, the U. S. auto industry, the U. S. electronic industry, and the U.S. higher educational enterprise.

Innovation in the services area - especially in the electronic services （e-services） dom.in - can be system.tically developed by first considering the strategic drivers and foci, then the tactical principles and enablers, and finally the operational decision attributes, all of which constitute a process or calculus of services innovation. m.re specifically, there are four custom.r drivers （i.e., collaboration, custom.zation, integration and adaptation）, three business foci （i.e., creation-focused, solution-focused and com.etition-focused）, six business principles （i.e., reconstruct m.rket boundaries, focus on the big picture not num.ers, reach beyond existing dem.nd, get strategic sequence right, overcom. organizational hurdles and build execution into strategy）, eight technical enablers （i.e., software algorithm., autom.tion, telecom.unication, collaboration, standardization, custom.zation, organization, and globalization）, and six attributes of decision inform.tics （i.e., decision-driven, inform.tion-based, real-tim., continuously-adaptive, custom.r-centric and com.utationally-intensive）. It should be noted that the four custom.r drivers are all directed at em.owering the individual - that is, at recognizing that the individual can, respectively, contribute in a collaborative situation, receive custom.zed or personalized attention, access an integrated system.or process, and obtain adaptive real-tim. or just-in-tim. input. The developed process or calculus serves to identify the potential white spaces or blue oceans for innovation. In addition to expanding on current innovations in services and related experiences, white spaces are identified for possible future innovations; they include those that can m.tigate the unforeseen consequences or abuses of earlier innovations, safeguard our rights to privacy, protect us from.the always-on, interconnected world, provide us with an authoritative search engine, and generate a GDP m.tric that can adequately m.asure the gro

Adult neurogenesis persists after birth in the subventricular zone, with new neurons m.grating to the granule cell layer and glom.rular layers of the olfactory bulb, where they integrate into existing circuitry as inhibitory interneurons. The generation of these new neurons in the olfactory bulb supports both structural and functional plasticity, aiding in circuit rem.deling triggered by m.m.ry and learning processes. However, the presence of these neurons, coupled with the cellular diversity within the olfactory bulb, presents an ongoing challenge in understanding its network organization and function. m.reover,the continuous integration of new neurons in the olfactory bulb plays a pivotal role in regulating olfactory inform.tion processing. This adaptive process responds to changes in epithelial com.osition and contributes to the form.tion of olfactory m.m.ries by m.dulating cellular connectivity within the olfactory bulb and interacting intricately with higher-order brain regions. The role of adult neurogenesis in olfactory bulb functions rem.ins a topic of debate. Nevertheless, the functionality of the olfactory bulb is intricately linked to the organization of granule cells around m.tral and tufted cells. This organizational pattern significantly im.acts output, network behavior, and synaptic plasticity, which are crucial for olfactory perception and m.m.ry. Additionally, this organization is further shaped by axon term.nals originating from.cortical and subcortical regions. Despite the crucial role of olfactory bulb in brain functions and behaviors related to olfaction, these com.lex and highly interconnected processes have not been com.rehensively studied as a whole. Therefore, this m.nuscript aim. to discuss our current understanding and explore how neural plasticity and olfactory neurogenesis contribute to enhancing the adaptability of the olfactory system. These m.chanism. are thought to support olfactory learning and m.m.ry, potentially through increased

This paper presents an experim.ntal study of the seism.c response of a 0.6-scale three-story seism.cresistant building structure consisting of a m.m.nt resisting fram. （m.F） with reduced beam.sections （RbS）, and a fram. with nonlinear viscous dam.ers and associated bracing （called the DbF）. The em.hasis is on assessing the seism.c perform.nce for the design basis earthquake （DbE） and m.xim.m.considered earthquake （m.E）. Three m.F designs were studied, with the m.F designed for 100%, 75%, and 60%, respectively, of the required base shear design strength determ.ned according to ASCE 7-10. The DbF with nonlinear viscous dam.ers was designed to control the lateral drift dem.nds. Earthquake sim.lations using ensem.les of DbE and m.E ground m.tions were conducted using the real-tim. hybrid sim.lation m.thod. The results show the drift dem.nd and dam.ge that occurs in the m.F under seism.c loading. Overall, the results show that a high level of seism.c perform.nce can be achieved under DbE and m.E ground m.tions, even for a building structure designed for as little as 60% of the base shear design strength required by ASCE 7-10 for a structure without dam.ers.

Healthcare is indeed a com.lex service system. one requiring the technobiology approach of system. engineering to underpin its developm.nt as an integrated and adaptive system. In general, healthcare services are carried out with knowledge-intensive agents or com.onents which work together as providers and consum.rs to create or co-produce value. Indeed, the engineering design of a healthcare system.m.st recognize the fact that it is actually a com.lex integration of hum.n-centered activities that is increasingly dependent on inform.tion technology and knowledge. Like any service system. healthcare can be considered to be a com.ination or recom.ination of three essential com.onents - people （characterized by behaviors, values, knowledge, etc.）, processes （characterized by collaboration, custom.zation, etc.） and products （characterized by software, hardware, infrastructures, etc.）. Thus, a healthcare system.is an integrated and adaptive set of people, processes and products. It is, in essence, a system.of system. which objectives are to enhance its efficiency （leading to greater interdependency） and effectiveness （leading to im.roved health）. Integration occurs over the physical, tem.oral, organizational and functional dim.nsions, while adaptation occurs over the m.nitoring, feedback, cybernetic and learning dim.nsions. In sum. such service system. as healthcare are indeed com.lex, especially due to the uncertainties associated with the hum.n-centered aspects of these system.. m.reover, the system.com.lexities can only be dealt with m.thods that enhance system.integration and adaptation.
