The History, Trend, Types, and Mitigation of Distributed Denial of Service Attacks

Over time, the world has transformed digitally and there is total dependence on the internet. Many more gadgets are continuously interconnected in the internet ecosystem. This fact has made the Internet a global information source for every being. Despite all this, attacker knowledge by cybercriminals has advanced and resulted in different attack methodologies on the internet and its data stores. This paper will discuss the origin and significance of Denial of Service (DoS) and Distributed Denial of Service (DDoS). These kinds of attacks remain the most effective methods used by the bad guys to cause substantial damage in terms of operational, reputational, and financial damage to organizations globally. These kinds of attacks have hindered network performance and availability. The victim’s network is flooded with massive illegal traffic hence, denying genuine traffic from passing through for authorized users. The paper will explore detection mechanisms, and mitigation techniques for this network threat.

Organic heterojunction synaptic device with ultra high recognition rate for neuromorphic computing

Traditional computing structures are blocked by the von Neumann bottleneck,and neuromorphic computing devices inspired by the human brain which integrate storage and computation have received more and more attention.Here,a flexible organic device with 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene(C8-BTBT)and 2,9-didecyldinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene(C10-DNTT)heterostructural channel having excellent synaptic behaviors was fabricated on muscovite(MICA)substrate,which has a memory window greater than 20 V.This device shows better electrical characteristics than organic field effect transistors with single organic semiconductor channel.Furthermore,the device simulates organism synaptic behaviors successfully,such as paired-pulse facilitation(PPF),long-term potentiation/depression(LTP/LTD)process,and transition from short-term memory(STM)to long-term memory(LTM)by optical and electrical modulations.Importantly,the neuromorphic computing function was verified using the Modified National Institute of Standards and Technology(MNIST)pattern recognition,with a recognition rate nearly 100%without noise.This research proposes a flexible organic heterojunction with the ultra-high recognition rate in MNIST pattern recognition and provides the possibility for future flexible wearable neuromorphic computing devices.

Impact of Organisational Distance on Technology Standard Alliance Performance:The Mediating Role of Ambidextrous learning

Technology standards are key elements for enterprises to dominate a market.The globalisation of innovation has intensified standard competition,making it generally difficult for a single enterprise to obtain all the resources needed to develop standards.Therefore,enterprises actively join technology standard alliances(TSAs)to seek collaborative innovation and develop technology standards to gain more competitive advantages.This study addresses a crucial issue for enterprises in TSAs and attempts to help them overcome the confines of organisational distance(OD)and improve technology standard alliance performance(TSAP).Through an empirical study of 325 Chinese information and manufacturing enterprises participating in TSAs,we find that OD negatively affects TSAP,and that exploratory learning(ERL)and exploitative learning(EIL)play mediating roles in the relationship between OD and TSAP.The innovation climate(IC)plays a moderating role in the relationship between OD and ERL,and OD and EIL.The results might deepen the understanding of OD in the context of TSAs and have implications for enterprise standardisation practices.

Which Plays a Decisive Role in Technology Licensing Involved in Technology Standards, Patented Technology or Know-how？

It is wen-known that patented technology licensing is closely related to technology standards, and whether a technology standard contains a specific patented technology solution or not, there is always a patented technology hcensing imphed, for patented technology hcensing is a prerequisite for the existence and development of technology standards. Therefore, technology standards create a good many potential chances for hcensing patented technologies concerning them. Superficially speaking, patent holders achieve huge profits mainly by means of hcensing patented technologies through a standard mainly in the form of a patent pool; however, in fact, it is know-how licensing behind the patented technology involved in the standard that really helps patent holders make huge profits.
