In this paper, we design NETHCF, a line-rate in-network system for filtering spoofed traffic. NETHCF leverages the opportunity provided by programmable switches to novel defense against IP traffic, and it is highly efficient adaptive. One key challenge stems from restrictions of computational model memory resources switches. We address decomposing HCF into two complementary components-one component data plane another control plane. also aggregate IP-to-Hop-Count (IP2HC) mapping table usage,...

A short lifetime, low phosphorescence quantum efficiency (PQE), and unstable room-temperature (RTP) in oxidants solvents are the core problems development of carbon dot (CD)-based RTP materials for anticounterfeiting applications. Herein, a series CDs/Al2O3 nanocomposites with excitation-dependent properties were fabricated by sol–gel process followed high-temperature treatment. The crystalline structure rigid Al–O network Al2O3 matrix could readily benefit stabilization triplet excited...

Gradient porous carbon has become a potential electrode material for energy storage devices, including the aqueous zinc-ion hybrid capacitor (ZIHC). Compared with sufficient studies on fabrication of ZIHCs high electrochemical performance, there is still lack in-depth understanding underlying mechanisms gradient structure storage, especially synergistic effect ultramicropores (<1 nm) and micropores (1-2 nm). Here, we report design principle used ZIHC based data-mining machine learning (ML)...

Critical-sized bone defect regeneration remains a significant clinical challenge due to the complex cascade of biological processes involved. To address this, we developed sophisticated hierarchical biomembrane (PCS@MPN10) designed modulate osteogenic microenvironment. Using coaxial electrospinning, fabricated core–shell structure with polylactic acid (PLA) as membrane base, incorporating simvastatin in core and chitosan shell. The surface was further modified tannic acid-iron...

Software-Defined Networking (SDN) has attracted great attention from both academia and industry. However, the deployment of SDN faced some critical security issues, such as Denial-of-Service (DoS) attacks on infrastructure. One DoS attack is data-to-control plane saturation attack, where an attacker floods a large number packets to trigger massive table-misses packet-in messages in data plane. This can exhaust resources different components infrastructure, including TCAM buffer memory plane,...

Software-Defined Networking (SDN) continues to be deployed spanning from enterprise data centers cloud computing with the proliferation of various SDN-enabled hardware switches and dynamic control plane applications. However, state-of-the-art have rather limited downlink message processing capability, especially for Flow-Mod Statistic Query, which may not suffice huge need In this paper, we systematically study interactions between applications switches, present two new attacks, namely...

One key challenge design is handle restrictions stemmed from limited computational model memory resources switches. We address by decomposing HCF scheme into two complementary parts, aggregating IP-to-Hop-Count (IP2HC) mapping table for efficient usage, designing adaptive mechanisms...

It is unclear why primary nephrotic syndrome (PNS) patients often have dyslipidemia. Recent studies shown that angiopoietin-like protein 3 (ANGPTL3) an important regulator of lipid metabolism. In this study, we explored how ANGPTL3 impacts dyslipidemia during PNS development.We measured the serum levels in (n=196). Furthermore, degree proteinuria and metabolism were examined angptl3-overexpressing transgenic (angptl3-tg) mice at different ages. Moreover, used clustered regularly interspaced...

Cloud gateways are fundamental components of a cloud platform, where various network functions (e.g., L4/L7 load balancing, address translation, stateful firewall, and SYN proxy) deployed to process millions connections billions packets. Providing high-performance failure-resilient packet processing with scalable traffic management mechanism is crucial ensuring the quality service provider, hence great importance. Many nowadays implemented in software commodity servers for low cost high...

We have developed a self-powered near-infrared photodetector (PD) with high detectivity using tensile strained Ge layer capped thick Si layer. The acts as stressor and maintains the strain of minimal dislocations by creating rough surface. By Raman spectroscopy, we confirmed that has 1.83% in-plane strain. PD exhibits responsivity 0.45 A/W at -1 V bias voltage for 940 nm wavelength. PD's dark current density is low ∼1.50 × 10 −6 A/cm 2 V. result in 6.55 11 cmHz 1/2 /W. This great potential...

Modern traffic analysis applications are usually designed to identify malicious behaviors by inferring sensitive information with machine learning (ML) techniques from network traffic, and they of great importance security the growing use encryption other evasion that make classic content-based infeasible. However, soaring throughput networks reaching hundreds Gbps, it becomes more challenging for keep up today's high-speed large-volume traffic. In particular, existing feature extractor...

Multi-string pattern matching is a crucial building block for many network security applications and thus of great importance. Since every byte packet has to be inspected by large set patterns, it often becomes bottleneck these dominates the performance an entire system. Many existing studies have been devoted alleviating this either algorithm optimization or hardware acceleration. However, neither one provides desired scalability costs that keep pace with drastic increase in bandwidth...
