For achieve fast and reliable power data transmission, we propose a novel Intensity Modulation and Direct Detection (IM/DD) optical Orthogonal Frequency Division Multiplexing (OFDM) system. In this system, we utilize Discrete Hartley Transform (DHT) instead of Discrete Fourier Transform (DFT) which is...

Fifteen isomers of cyclooctene systems calculated in ab initio reveal the potency of computational results as a sufficient approach to distinguish different isomers and their configurational and conformational isomers within the system. The optimized geometries obtained from the semi empirical calculations...

Interaction of three cationic porphyrins: meso-tetrakis (N-methylpyridinium-4-yl) porphyrin (H2TMPyP), meso-tetrakis (1,3-dimethylimidazolium-2-yl)porphyrin (H2TDMImP), and meso-tetrakis(1,2-dimethylpyrazolium-4-yl) porphyrin (H2TDMPzP) with lead have been performanced computationally using DFT method....

This qualitative descriptive study aimed to describe the profile of understanding layer of the Conic Section concept toward Mathematics Education Students 2016 of FKIP UKSW. The understanding layer includes eight layers, Primitive Knowing (Pk), Image Making (Im), Image Having (Ih), Property Noticing...

Purpose: Delirium is a frequent occurrence amongst Intensive Care Unit (ICU) patients, but studies on its causes are sparse and its risk factors vary from disease to disease. Here, in this study, an attempt was made to investigate the factors associated with the prognosis of delirium in the ICU. Methods:...

The construction industry faces increasing pressure to reduce carbon emissions due to environmental concerns and regulatory demands. Traditional cement-based concrete production contributes significantly to CO₂ emissions, primarily due to the energy-intensive cement manufacturing process. This study...

In communications engineering, we often encounter some problems of the data analysis and processing aspects, therefore analysis of engineering data throughout the project has become a crucial part. LabVIEW is a program development environment, it is developed by National Instruments (NI) company developed,...

In this study, the adsorption of hazardous atoms including lead on the silica surface (SiO2 [001]) was investigated using the first-principles method within the framework of density functional theory (DFT). We performed the full structural optimization and found the most stable configuration. Four different...

Due to the recent improvement in computer performance and computational tools, deep convolutional neural networks (CNNs) have been established as powerful class of models in various problems such as image classification, recognition, and object detection. In this study, we address two fundamentally dissimilar...

At present, most of the researches on relationship between ICT and social impact are focused on specific communication technology. This paper discusses the impact of ICT on social life with the perspective of networked individualism. In order to answer the problem efficiently, we present the relationship...

The Programmed Cell Death 1 (PD-1)/Programmed Death Ligand 1 (PD-L1) Immune Checkpoint Inhibitors (ICIs), have become a hot spot in the field of cancer research and treatment, and bring new hope to patients with advanced tumors. But, in addition to enhancing the anti-tumor effect of T cells, PD-1/PD-L1...

Grey scale median of the common carotid artery intima-media complex (IM-GSM) characterizes the composition of the arterial wall and low IM-GSM reflects more generalized atherosclerotic vulnerability. However, it is unclear whether the presence of DM itself affects IM-GSM, similar to that observed with...

The precise analysis of long jumper’s technical videos can provide the im-portant information for the coaches to formulate the training program. To real-ize the analysis of technical videos, we must firstly detect and track the long jumpers in the video. OpenCV technique (open source computer vision...

This study compared and analyzed the speech recognition performance of Korean phonological rules for cloud-based Open APIs, and analyzed the speech recognition characteristics of Korean phonological rules. As a result of the experiment, Kakao and MS showed good performance in speech recognition. By phonological...

Low speed skid resistance measurement is of great significance to analyse the actual causes of insufficient friction of pavement, and to formulate appropriate maintaining measures. At present, the British Pendulum Tester (BPT) and Dynamic Friction Tester (DFT) are commonly used to measure the low-speed...

In this study, we report the design and investigation of a Janus MoWC monolayer, derived from pristine Mo2C MXene through first-principles calculations based on density functional theory (DFT). By introducing compositional asymmetry in the MXene structure, we aim to tune its electronic and catalytic...

The decarboxylation mechanism of oxaloacetate catalyzed by transition metal ions M(?...?) (M=Cu, Zn, Co) has been studied using Density Functional Theory (DFT). The calculations show that the catalytic cycle contains two stages: the formation of oxaloacetate-M(?...?) complexes, and the cleavage of the...

Aim: To validate strategies to guide nurse educators to strengthen the clinical accompaniment of nursing students through the practice of caring presence. Background: Good-quality nursing education and practice involve a balance of knowledge and a holistic-caring approach to students. Quality nursing...

Sepsis is a life-threatening organ dysfunction caused by a deregulated host response to infection, and is the most common cause of death in the intensive care unit. Although the pathogenesis of sepsis has made substantial progress, the current clinical treatment of sepsis is basically symptomatic treatment,...

In view of the current most based on Fourier transform domain method, its resist geometric attacks performance is very good, the embedded information is also big, but there are shearing attack ability is bad problems, and put forward a kind of based on singular value decomposition and discrete Fourier...

With modulus (KH = 0.89, SM = 2.42, IM = 1.70), substituting the sludge for the shale in the calculation of the cement burden, we studied the influence of different amount of sludge on the cement raw meal sintering, mineral composition, compression strength and the leaching value of heavy metal element....

Channel equalizer is a key component of WSN-OFDM (Wireless Sensor Networks Orthogonal Frequency Division Multiplexing) system. Traditional equalizer is mostly designed with LS algorithm, which comes with low precision in channel estimation. The previous LMMSE algorithm could reach a high accuracy, but...
