This paper presents our extensive investigation of the security aspects control plane procedures based on dynamic testing components in operational Long Term Evolution (LTE) networks. For LTE networks, we implemented a semi-automated tool, named LTEFuzz, by using open-source software over which user has full control. We systematically generated test cases defining three basic properties closely analyzing standards. Based property, LTEFuzz generates and sends to target network, classifies...
The low mechanical properties and printing speed of fused filament fabrication (FFF) have remained important barriers to their widespread adoption in the industry. This study focused on proposal a layer stacking scheme that increases reduces time through continuously varied Infill Pattern (ConVIP). ConVIP method showed 15.2% 40% ultimate tensile strength, elongation at break, compared conventional infill pattern within polylactic acid (PLA) filament. In addition, had been increased by 29.37%...
This study evaluated the fracture resistance, biaxial flexural strength (BFS), and dynamic mechanical analysis (DMA) of three-dimensional (3D) printing resins for esthetic restoration primary molars. Two 3D resins, Graphy (GP) NextDent (NXT), a prefabricated zirconia crown, NuSmile (NS), were tested. GP NXT samples printed using workflow recommended by each manufacturer. Data collected statistically analyzed. As result resistance test 0.7-mm-thick resin crowns with thickness similar to that...
Among the various 3D printing methods, direct ink writing (DIW) through extrusion directly affects microstructure and properties of materials. However, use nanoparticles at high concentrations is restricted due to difficulties in sufficient dispersion deteriorated physical nanocomposites. Thus, although there are many studies on filler alignment with high-viscosity materials a weight fraction higher than 20 wt %, not much research has been done low-viscosity nanocomposites less 5 phr....

This article presents an energy-harvesting (EH) interface chip system for triboelectric nanogenerators (TENGs). Despite TENG's numerous advantages, its high open-circuit voltage and large parasitic capacitance ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$C_{T}$ </tex-math></inline-formula> ) give a considerable burden to design TENG-EH integrated circuits (ICs). In this work, scalable...
This paper presents an OLED/μLED display driver IC with cascaded loading-free capacitive interpolation (LFCI) DAC and a high-slew buffer amplifier. The 12-bit color-depth is realized by combination of 7-bit R-DAC proposed 5-bit LFCI while occupying only 295×17μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , which ×2 reduction compared to the state-of-the-art.

In this paper, we investigate the system outage performance of full-duplex (FD) two-way relay networks where all nodes are equipped with FD multiple-input multiple-output (MIMO) capability and two sources exchange information via decode-and-forward (DF) protocol in consecutive time slots. order to completely separate desired signal interference, consider a finite size buffer at relay. We propose zero-forcing based beamforming schemes for different cases buffer-aided non-buffer-aided derive...
Abstract We consider infinitely wide multi-layer perceptrons (MLPs) which are limits of standard deep feed-forward neural networks. assume that, for each layer, the weights an MLP initialized with independent and identically distributed (i.i.d.) samples from either a light-tailed (finite-variance) or heavy-tailed distribution in domain attraction symmetric $\alpha$ -stable distribution, where $\alpha\in(0,2]$ may depend on layer. For bias terms we i.i.d. initializations having same parameter...
Increasing power density—delivering more in a smaller footprint—stands as pervasive trend across multiple markets, including the sector for buck DC-DC converters. One of cardinal challenges achieving optimized density is navigating intrinsic trade-off between an inductor's volume and its parasitic DC resistance (DCR); miniaturizing inductor invariably leads to elevated DCR. To enhance efficiency even when using compact inductors, many hybrid converter topologies have been investigated [1–4]....
The members of the avidin protein family are well known for their high affinity towards d-biotin and structural stability. These properties make avidins a valuable tool various biotechnological applications. In present study, two avidin-like biotin-binding proteins (named streptavidin C1 C2) from Streptomyces cinnamonensis were newly identified while exploring antifungal against Fusarium oxysporum f. sp. cucumerinum. Streptavidin reveals low correlation (a sequence identity approximately...
Triboelectric nanogenerators (TENGs) for collecting ambient mechanical vibration energy have gained popularity as a next-generation source owing to their numerous advantages including flexibility, high conversion efficiency, and low cost. However, ultra-high instantaneous open-circuit voltage (~110V) is the fundamental feature of TENGs, thus they are not very compatible with integrated circuits. Recent TENG-harvesting chips [1]–[3] fabricated in high-voltage BCD been reported be capable...
