Authors: H. Rabadi Meheroz , Just Kimberly , Xu Chao
Published: October 2022

Objective: To investigate the association of daily dose-dependent Vitamin-D supplement on clinical outcomes including mortality in veterans with
multiple sclerosis (MS) with low serum Vitamin-D (25[OH]D) levels. This Methods: observational, longitudinal study reports on data collected
from 1/1/2000 to 12/31/2020 at the MS Regional Program. We reviewed the electronic records of 163 veterans with MS who were followed every
four months in our MS clinic. The study sample was divided into three groups based on the daily Vitamin-D supplement doses: low (1000 IU/day),
medium (2000 IU/day) and high (4000 IU/day). The clinical outcomes were changes in physical disability (Expanded Disability Severity Scale
(EDSS)), function (Total Function Independence Measures (TFIM)), time-to-event EDSS score of 6 (progressive MS) and mortality. Results:
There were 32 patients in the low, 46 in the medium, and 85 in the high-dose daily Vitamin-D supplement groups. The mean age of the entire study
sample was 51 12 SD years (range 23 - 79 years). The mean duration of MS was 21.7 13 years. The mean initial EDSS and TFIM scores were 3.4
2.8 and 111 17 SD. At entry, mean serum 25[OH]D and calcium levels were 30 16 nmol/l and 9.3 0.4. The risk of MS-related progressive
disability (time-to-event EDSS score 6) was lower and there were fewer deaths in the high- (compared to low- and medium-) dose groups.
Conclusion: This study suggests that among veterans with MS and low 25[OH]D levels, those who received high-doses daily of supplemental
Vitamin-D supplement were associated with a decreased risk of MS-related progressive disability and death than those who received a lower dose.
No adverse clinical or biochemical events were noted.

Presence of microbes in blood i.e. bacteremia carries high risk of morbidity and mortality. Blood cultures form a critical part of evaluation of
patients with suspected sepsis. The present study was undertaken to study the effect of duration of incubation for obtaining positive cultures. Atotal
of 220 samples from 107 pediatric patients presenting with suspected bacteraemia were processed aerobically. Cultures were positive in 24.3% of
the samples. But, following repeat cultures, only 18.7% were identied as true or persistent bacteremias. Blood cultures positive for isolates
having doubtful pathogenicity have to be conrmed by repeat cultures or isolation from other sets to conrm the true bacteremias.
Statistical-mechanical analysis of adaptive filter with clipping saturation-type nonlinearity
Authors: Miyoshi Seiji
Published: October 2022

In most practical adaptive signal processing systems, e.g., active noise control, active vibration control, and acoustic echo cancellation, substantial nonlinearities that cannot be neglected exist. In this paper, we analyze the behaviors of an adaptive system in which the output of the adaptive filter has the clipping saturation-type nonlinearity by a statistical-mechanical method. We discuss the dynamical and steady-state behaviors of the adaptive system by asymptotic analysis, steady-state analysis, and numerical calculation. As a result, it has become clear that the saturation value has the critical point at which the system's mean-square stability and instability switch. The obtained theory well explains the strange behaviors around the critical point observed in the computer simulation. Finally, the exact value of the critical point is also derived.
Beyond-Cell Communications via HAPS-RIS
Authors: Alfattani Safwan , Yadav Animesh , Yanikomeroglu Halim , Yongacoglu Abbas
Published: October 2022

The ever-increasing number of users and new services in urban regions can lead terrestrial base stations (BSs) to become overloaded and, consequently, some users to go unserved. Compounding this, users in urban areas can face severe shadowing and blockages, which means that some users do not receive a desired quality of service (QoS). Motivated by the energy and cost benefits of reconfigurable intelligent surfaces (RIS) and the advantages of high altitude platform stations (HAPS), including their wide footprint and strong line-of-sight (LoS) links, we propose a solution to service the stranded users using the RISaided HAPS. More specifically, we propose to service the stranded users by a dedicated control station (CS) via a HAPS equipped with RIS (HAPS-RIS). Through this approach, users are not restricted from being serviced by the cell they belong to; hence, we refer to this approach as beyond-cell communication. As we demonstrate in this paper, beyond-cell communication works in tandem with legacy terrestrial networks to support uncovered or unserved users. Optimal transmit power and RIS unit assignment strategies for the users based on different network objectives are introduced. Numerical results demonstrate the benefits of the proposed beyond-cell communication approach. Moreover, the results provide insights into the different optimization objectives and their interplay with minimum quality-of-service (QoS) and network resources, such as transmit power and the number of reflectors. 
Distributed Precoding For Decentralized Estimation In Coexisting IoT Networks
Authors: Garg Navneet , Ratnarajah Tharmalingam , Vakamulla Venkata Mani , Sellathurai Mathini
Published: October 2022

With the increasing number of applications of internet-of-things (IoT) devices, co-channel interference is unavoidable among coexisting wireless networks, where multiple IoT devices transmit their observations to their respective destinations (access points (APs)). In this scenario, we present a joint precoding and power allocation solution to minimize the mean squared error (MSE), while satisfying power constraints at individual IoT devices. In this regard, first, the necessary feasibility condition for the joint convexity of the  optimization problem is derived, ensuring the global optimum solution. Subsequently, based on the solution, an iterative MSE algorithm is formulated and analyzed for convergence. Further analysis shows that the total resulting MSE at APs is limited by the observation signal-to-noise-ratio (SNR). It leads to the inference that in order to avoid the MSE saturation at APs at higher SNRs, the transmit power at IoT devices should be scaled proportional to and  less than the observation SNR. Next, we compare the performance of our solution with two classical methods, namely, the minimum variance distortionless precoding (MVDP) and interference alignment (IA) methods, which are modified and enhanced for the given system. Simulations verify the above inference, and the global convergence of the MSE algorithm,  with robustness to initializations yielding the better precoders and power allocation as compared to MVDP's and IA's in terms of the averaged total MSE performance.
Electromagnetic Analysis of Attenuated Total Reflection Spectra of Water in Bulk and Films Forms at Terahertz Frequencies
Authors: Strupiechonski Elodie , Justo Guerrero Manuel Alejandro , Mendoza-Glaván Artuto
Published: October 2022

Terahertz attenuated total reflectance (THz-ATR) is being extensively used for spectroscopy and imaging applications in materials science, chemistry, and biomedical research. One of the driving motivations is its potential for studying protein dynamics, identifying living tissues, or detecting herbicide traces, as a non-destructive and non-ionizing technique. It is well known that studying biological and chemical samples in the terahertz range represents a real challenge because of the presence of water, which is highly absorbing. In this work, we present experimental data from THz-ATR spectroscopy of water in the 1-15 THz frequency range and propose an insightful interpretation of the optical phenomenon that is taking place in this experiment, supported by finite-element-method simulations and an analytical model. Interestingly, this study reveals that there is no evanescent field at the interface between the crystal and water, but that a refracted beam is propagating through the water, independently from the value of the angle of incidence. These findings improved the signal intensity after a simple modification of the accessory, by creating a thin film of micrometer thickness with a top mirror. We believe that this technique could lead to highly sensitive terahertz microfluidic systems for chemical and biomolecular detection.
DCGCN: Dynamic community graph convolutional network for traffic forecasting
Authors: Xu Yi , Zhang Dalin , Peng Yunjuan , Wang Nan , Lu Lingyun , Liu Jiqiang
Published: October 2022

Traffic forecasting is one of the core issues in transportation systems. Graph convolution based spatiotemporal model can process the complex and highly nonlinear traffic data, but rely heavily on the graph construction, some creative works make innovations in dynamic graph modeling and expansion of the graph. However, these works ignored the dynamic community structure of traffic graph and the inter-community traffic flow interaction, and not fully exploited the spatiotemporal characteristics. In this paper, we propose a dynamic community graph convolution model (DCGCN), which can more precisely characterize the dynamic traffic network and capture the dynamic spatiotemporal dependencies by capturing the community properties and community interactions of traffic flow. First, we propose a noval method to capture inter-community traffic flow interactions. Second, we take advantage of the spatiotemporal properties of traffic data and introduce a community-based dynamic traffic graph learning mechanism to construct traffic networks adaptively. Finally, we fuse inter-community traffic flow interactions and dynamic traffic graph to update the traffic graph, introduce a multi-attention spatiotemporal convolution for traffic forecasting. We conduct experiments on three large-scale real datasets containing multiple traffic scenarios, prove the superiority of our model compared with SOTA models such as ASTGCN, MATGCN, and DCRNN. Meanwhile, the visualization in these datasets shows the method can effectively identify the stations that have a large impact in the forecasting process and dynamic community changes, and the extracted inter-station dependencies and traffic flow region interactions are interpretable.

Measuring Spatio-Temporal Civil War Dimensions Using Community-Based Dynamic Network Representation (CoDNet)
Authors: Vega Oliveros Didier Augusto , Koren Ore
Published: October 2022

Civil war exhibits complex geospatial trends over time, which may be missed by models that rely on count-based operationalizations. Here, the spatial and temporal correlation values of monthly civil war events are transformed into their influence degree symbol, which measures geospatial concentration, spread, and intensity of civil war. We then measure variation in these degrees over time to identify relevant Spatio-temporal civil war aspects. The network model is constructed using 0.5 degree grid locations as nodes, counting nearby and over-time connections. We then extract the temporal community structure behind the data. We use ground truth data to visualize how our measures correlate with observed patterns, thereby illustrating our method provides accurate depictions of geospatial civil war dynamics. We also evaluate the impact of several indicators highlighted by past research and our community-based spatio-temporal measures and comparing it to the preprocessed count indicator. Our findings indicate that the relationship between state capacity and climate stress show opposite correlations with civil war as those identified by studies that use count based indicators. Counterintuitively, our results show that conflict intensifies and spreads in locations where the state is stronger and where climate conditions are improved.

Comparing 4G and 5G downlink energy consumption
Authors: Peng Li
Published: October 2022

During the deployment of 5G it has become apparent that 5G base stations consume excessive amounts of energy. However, there has been little investigation or discussion of this issue in theoretical research circles. This article examines this problem by comparing 4G and 5G from three perspectives: theoretical analysis of communication systems; their high-order modulation constellations and carrier aggregation; and their base station downlink schemes in industrial standard. The basic conclusion is that the mobile communication system with multiple modulation technologies is designed theoretically by considering energy efficiency and spectral efficiency, but the actual energy consumption exceeds the operator's expectation. On the basis of this, possible future directions for improving spectrum efficiency and reducing energy consumption are proposed.
Characterization and Anomaly Reasoning in Signaling & Power Cables

Power and signaling infrastructure comprise of electrical installations, electronic systems and cables. A damage to these cables will be catastrophic or at the least significant downtime to the system. Hence, monitoring these cables in real-time not only improves the efficiency of the system but can also avoid fatal accidents. In this work, we develop a non-invasive composite diagnostic framework to identify cable damages such as insulation cuts. The framework can detect, classify, and locate faults. While the solution is general enough, we consider two use cases: (a) railway cables used in signalling applications and(b) symmetrical four-core cables used in residential buildings. In order to characterize the faults, we use three non-invasive sensors: (a) SNR sensor, (b) S-parameter, and (c) Correlation peak sensor. We use a single programmable hardware to implement each of these sensors. These sensors monitor a parameter change on the cable in real-time. The experimental insights gained are used to construct an a priori Bayesian network depicting the non-deterministic relationship between an effect and its causes. This uncertainty is due to inhibitors such as sensor calibration issues and coupling mismatch between sensor transceivers suitably handled through a Noisy-OR function. The results of Bayesian inference with belief propagation provides up to 97% match with the ground truth state. Regarding the cable fault, our experimental results show a best-case detection and localization accuracy of 98% & 97.2% respectively.
Reducing the Latency using Fog Computing with IoT in Real Time

Published: October 2022

In today's modern world, the Internet is highly crucial. A larger number of wired and wireless sensors characterize the Internet of Things (IoT). These sensors are networked devices that create massive amounts of data, reaction time, latency, and security vulnerabilities. These problems create delay in decision making in some situation which is very extreme in case of Healthcare, Smart vehicles, Industry 4.0 etc., the data moving from the sensor devices have to reach the cloud and from there it has to reach back to receivers. Therefore, in order deal with such huge data we use fog computing, a well-known distributed architecture. Fog computing works with the aim to enhance the processing, intelligence, and accumulation of data closer to the Edge devices. The proposed framework helps in reduce latency as we place a Fog node device between the cloud and the edge device where data is generated and sent to the cloud and retrieved from the cloud. The framework is designed in such way that the different sensor devices can be placed on it and collects the sensor data from them. To test the framework functioning, without the fognode and with the fognode, comparing the latency with packet transfer rate from sensor devices to the cloud and vice versa. In this paper, we are considering two different case studies to test the proposed functioning of the framework with the following case studies i) Related to medical are like diabetes and cardiovascular illnesses are considered for prediction based on patient health records and ii) Vehicle theft where the owner get an alert of the theft of the vehicle within few seconds of the theft. In Medical case study initially, patient health data is acquired and stored using Sensor devices. 
A Framework for Road Boundary Detection based on Camera-LIDAR Fusion in World Coordinate System and Its Performance Evaluation Using Carla Simulator

Published: October 2022

Detection of road boundaries using camera-LIDAR fusion in world coordinate system poses several challenges. First, the pixels from the image need to be transformed into the world coordinate system, which is commonly done using inverse perspective mapping (IPM) technique. However, this technique is built based on assumptions that the road model is planar and rigid, assumptions that are not always held in real-world scenarios. Furthermore, obtaining the ground truth road boundaries is a difficult task for a real-world test, especially when the detection results are represented in world coordinate system. To solve the first challenge, this paper proposes a new framework for fusing camera and LIDAR data for detecting road boundaries using a transformation technique that can work on scenarios with varying and nonplanar roads. With this framework, we were able to fuse road boundary detection results that are extracted from camera and LIDAR separately. To overcome the second challenge, we used Carla Simulator and developed a method for extracting the ground truth points so that evaluation and comparison of various road boundary detection methods can be done properly. Based on our test results, the proposed transformation technique performed better than the widely used IPM technique. The results also show that our road boundary detection method can achieve error values below 0.3 m and reveal some key characteristics of camera and LIDAR-based detection method. Those characteristics were utilized to improve the fusion technique that is demonstrated in this paper.
