Abstract:
Introduction. Oroantral communications may arise as a result of pathological processes or iatrogenic situations, particularly in oral surgery and implantology, but are uncommon in periodontal plastic surgery. Case Presentation. A healthy 37-year-old female patient with 5 mm Miller Class II recession on the maxillary left second molar was referred for a root coverage procedure. While preparing the recipient bed for the graft, an oroantral communication was created. Schneiderian membrane was sutured to reduce the dimension of the communication and covered with a connective tissue graft. Finally, the flap was laterally and coronally moved, and the patient instructed about postoperative precautions. This procedure allowed to achieve a complete closure of the oroantral communication and good root coverage after an 8-month follow-up. Conclusions. Different authors described different techniques that can be used to close oroantral communications. Nevertheless, in this clinical case, it was shown that the oroantral communication may be closed without having to postpone the periodontal plastic surgery.

Full text
Abstract:
The ergodic capacity of fading channels modeled with aκ-μshadowed distribution is investigated to derive closed-form expressions. Theκ-μshadowed distribution is of particular interest because it contains, as special cases, other classical ones like one-side Gaussian, Rayleigh, Rician, Nakagami-m,κ-μ, and Rician shadowed distributions. The paper discusses the physical meaning of the distribution parameter variations and also their impact on the channel capacity. These results can be used to study the behavior of different channels like the ones in underwater acoustic communications, land mobile satellite systems, body centric communications, and other wireless communication applications. The analytical closed-form expression results are validated with numerical simulations.

Abstract:
High capacity and ultra-reliable vehicular communication are going to be important aspects of beyond 5G communication networks. However, the vehicular communication problem becomes complex at a large scale when vehicles are roaming on the road, while simultaneously communicating with each other. Moreover, at higher frequencies (like 28 GHz), the dynamics of vehicular communication completely shift towards unpredictability and low-reliability. These factors may result in high packet error and a large amount of interference, resulting in regular disruptions in communications. A thorough understanding of performance variations is the key to moving towards the next generation of vehicular networks. With this intent, this article aims to provide a comprehensive interference analysis, wherein the closed-form expressions of packet error probability (PEP) and ergodic capacity are derived. Using the expression of the PEP, diversity analysis is provided which unveils the impact of channel nonlinearities on the performance of interference-constrained vehicular networks. The insights provided here are expected to pave the way for reliable and high capacity vehicular communication networks.

Abstract:
Abstract A vision based formation and attitude controller has been derived and simulated for the formation keeping of two 3U CubeSats. Four markers are installed on the leader CubeSat. Two cameras are installed on the follower CubeSat. An efficient vision based pose estimation method is used to estimate the pose of the follower with respect to the leader. A Higher-Order Sliding Mode (HOSM) exact differentiator with finite-time convergence is derived to estimate the rate of the follower’s pose parameters. The follower’s pose and its time rate are fedback to HOSM formation and attitude controllers to correct any gradual drift in formation and pose of the follower. The simulations show the effectiveness of the approach, and its feasibility on existing hardware.

Abstract:
When an earthquake or a large fire has occurred, it is difficult to secure communication networks for rescue in the building due to the destruction of commercial communication networks. Although analog radio systems such as VHF (Very High Frequency) and UHF (Ultra-High Frequency) are used for rescue operation in general, communication failure occurs in closed spaces, causing difficulties in smooth rescue operations. When the communication infrastructures have been destroyed in a building in the disaster, an emergency wireless telecommunication environment should be constructed to secure a safer disaster response environment. In this study, along with comparison of the performances of diverse communication frequencies, UWB (Ultra-Wide Band) wireless telecommunication networks were evaluated under five building indoor environment conditions including open spaces. UWB communication modules were fabricated to satisfy the IEEE (The Institute of Electrical and Electronics Engineers) 802.15.4a standard performance to measure distances in which communications are possible according to the indoor environment for each of six channels with different UWB communication frequencies. The results indicated that the distances in which communications are possible for each the six channels were average 15.5 m, maximum 20 m in open spaces; average 17.33 m, maximum 20 m in corridors; average 15.3 m, maximum 20 m in indoor office environments with office fixtures; average 4.33 m, maximum 6 m in vertical spaces of stairs; and average 6.5 m, maximum 17 m in closed horizontal spaces with a fire door. In this case, the communication performance and distance performance were shown to be the most excellent at a frequency (Centre Frequency) of 6489.6 and a band of 5980.3–6998.9 MHz, which is UWB 7ch. In conclusion, it is judged that if UWB communication modules are installed in the disaster area at intervals of 20 m and multi-channels are used, communication environments can be constructed even in closed spaces.

Abstract:
The safety and consistency of platoon-based driving are guaranteed via reliable communication between vehicles in a platoon. In this paper, we propose to exploit a full-duplex (FD) relay vehicle for millimeter-wave vehicular communications in platoon-based driving. Considering that a lead vehicle broadcasts information to all vehicles in a platoon, we consider two power allocation problems—maximizing broadcast information rates with a power constraint and minimizing power consumption with a quality-of-service constraint. In particular, for a four-vehicle platoon communication, we derive closed-form solutions for optimal power allocation and present numerical results to verify the performance of the proposed FD relay vehicles.

Abstract:
Orthogonal frequency division multiplexing(OFDM) is the multiple access scheme for the fourth generation(4G) wireless communications. This paper analyzes the performance of OFDM through the Bit Error Rate(BER), Outage Probability, and ergodic capacity with flat delay profile as well as linearly increasing power decay factor. The probability density function(PDF) obtained in a Rayleigh fading channel is used to derive a closed-form expression for the outage probability, error rates and ergodic capacity of OFDM signals. The exact error rate values are similar to those obtained from simulation results. The performance improves with more number of channel taps

Abstract:
Multiple-antenna systems are a promising approach to increase the data rate of wireless communication systems. One efficient possibility is spatial multiplexing of the transmitted symbols over several antennas. Many different MIMO detector algorithms exist for this spatial multiplexing. The major difference between different MIMO detectors is the resulting communications performance and implementation complexity, respectively. Particularly closed-loop MIMO systems have attained a lot of attention in the last years. In a closed-loop system, reliability information is fed back from the channel decoder to the MIMO detector. In this paper, we derive a basic framework to compare different soft-input soft-output MIMO detectors in open- and closed-loop systems. Within this framework, we analyze a depth-first sphere detector and a breadth-first fixed effort detector for different application scenarios and their effects on area and energy efficiency on the whole system. We present all system components under open- and closed-loop system aspects and determine the overall implementation cost for changing an open-loop system in a closed-loop system.

Abstract:
Objective The conduct of a medical interview is a challenging skill, even for the most qualified physicians. Since a training is needed to acquire the necessary skills to conduct an interview with a patient, we compared role-play with standardized patients (SP) training and a conventional lecture for the acquisition of communications skills in undergraduate medical students.Methods An entire promotion of third year undergraduate medical students, who never received any lessons about communications skills, were randomized into 4 arms: 1) SP 2 months before the testing of medical communications skills (SP); 2) conventional lecture 2 months before the testing (CL); 3) two control groups (CG) without any intervention, tested either at the beginning of the study or two months later. Students were blindly assessed by trained physicians with a modified 17-items Calgary-Cambridge scale.Results 388 students (98.7%) participated. SP performed better than CL, with significant statistical differences regarding 5 skills: the use of open and closed questions, encouraging patient responses, inviting the patient to clarify the missing items, encouraging of the patient’s emotions, and managing the time and the conduct of the interview. The SP group specifically improved communications skills between the SP training and testing sessions regarding 2 skills: the use of open and closed questions and encouraging patient responses. No improvements in communications skills were observed in CG between the two time points, ruling out a possible time effect.Conclusion Role-play with standardized patients appears more efficient than conventional lecture to acquire communication skills in undergraduate medical students.

Abstract:
The integration of unmanned aerial vehicles (UAVs) with a cognitive radio (CR) technology can improve the spectrum utilization. However, UAV network services demand reliable and secure communications, along with energy efficiency to prolong battery life. We consider an energy harvesting UAV (e.g., surveillance drone) flying periodically in a circular track around a ground-mounted primary transmitter. The UAV, with limited-energy budget, harvests radio frequency energy and uses the primary spectrum band opportunistically. To obtain intuitive insight into the performance of energy-harvesting, and reliable and secure communications, the closed-form expressions of the residual energy, connection outage probability, and secrecy outage probability, respectively, are analytically derived. We construct the optimization problems of residual energy with reliable and secure communications, under scenarios without and with an eavesdropper, respectively, and the analytical solutions are obtained with the approximation of perfect sensing. The numerical simulations verify the analytical results and identify the requirements of length of sensing phase and transmit power for the maximum residual energy in both reliable and secure communication scenarios. Additionally, it is shown that the residual energy in secure communication is lower than that in reliable communication.

Abstract:
A pilot study was performed to investigate whether the Göttingen minipig is a suitable animal model for creating and closing oroantral communications (OACs) and to test whether these defects can be closed with a biodegradable polyurethane (PU) foam. In three adult minipigs, an OAC was created on both sides of the maxilla. The left side was closed by a standard surgical buccal flap procedure, the right side by applying a PU foam. The pigs were killed after two weeks, one month and three months, respectively. Postmortem and histological examination showed that an OAC was created in only one of six cases. In the remaining cases, the infraorbital canal was perforated instead of the floor of the maxillary sinus. It was concluded that the Göttingen minipig is not a suitable animal model for OAC investigations. As a result, the closure of OACs with a biodegradable PU could not be evaluated.

Abstract:
Ion channels in the cell membrane spontaneously switch from states that are closed to the flow of ions such as sodium, potassium, and chloride to states that are open to the flow of these ions. The durations of times that an individual ion channel protein spends in the closed and open states can be measured by the patch clamp technique. We explore two basic issues about the molecular properties of ion channels: 1) If the switching between the closed and open state is an inherently random event, what does the patch clamp data tell us about the structure or motions in the ion channel protein? 2) Is this switching random?

Abstract:
The authentication scheme for vehicular ad hoc networks aims to improve the security and integrity of message delivery. The base station manages a large number of vehicular nodes, so the security communications are non-trivial. In this article, we propose an amplify-and-forward strategy for a dual-hop cooperative network in order to improve secure communications for vehicular ad hoc networks. We assume that each vehicular node equipped with a single antenna and derive closed-form expressions for the secure communication rate calculation. Moreover, we propose a cooperative strategy by jointly considering average power scaling and instantaneous power scaling, which are proved to be able to achieve information security. The simulation result shows that the proposed scheme can achieve better performance in scenarios with different signal-to-noise ratio.

Abstract:
Spatial Modulation is a kind of spatial multiplexing schemes conveying information by the location of transmit antennas and spatial modulation (SM) along with OFDM can be applied to visible light communications for higher data rates. The closed form of symbol error rate (SER) in optical SM-OFDM communication system is derived in this paper. SER is a convex function of power allocation coefficients, therefore there exist optimal allocation coefficients minimizing SER. The optimal allocation coefficients are derived for different channels and numbers of transmit antennas. Analytical results are validated by Monte Carlo simulation results and these results show that a significant SER improvement is obtained by using the power allocation. In addition, the optimal allocation coefficients are affected by the channel and number of transmitters.
