Private and Mobile inter-network routing for Wireless Sensor Networks and Internet of Things

In the last few years, using the Internet of Things has been expanded in many areas, such as environmental monitoring, industries, and smart home. Since the Internet of Things has a direct relation to human life, its security is of paramount importance. Therefore, the communication between the nodes should be secured and the valuable private information should be kept private so that the attacker cannot detect the network structure. This article provides a protocol that can handle routing privately. To do this, we use the data structure called Spatial Bloom Filter (SBF). In addition, the proposed protocol uses random identifiers instead of IP addresses, so that an attacker cannot collect network structure information and location of nodes from IP addresses. Using a homomorphic encryption scheme, the protocol prevent attackers from retrieving valuable network information, if they can infiltrate to one or more network nodes. Also, since almost all nodes in the internet of things are mobile, the structure of networks and subnets is constantly changing. The proposed protocol has the ability to manage to route in networks with a dynamic structure

Nova formulacija optimizacijskog problema za određivanje optimalnog dosega zona udaljenih releja uz stohastičko modeliranje neodređenosti

In this paper, by probabilistic modeling of uncertainties, the problem of determining the reach setting of distance relay zones is presented as a new optimization problem. For this purpose, uncertainties are modeled based on their probability density functions. Then, by using the Monte-Carlo process, the impedance seen by the distance relay is obtained. In this paper, probabilistic sensitivity and selectivity indices are defined for each zone of the distance relay. Therefore, the problem of determining the optimum reach setting of distance relay for each zone is converted to an optimization problem with the objective of maximizing of the probabilities indices of sensitivity and selectivity. The objective function and the constraints of the optimization problem are defined based on the protection philosophy of each of the three different zones of the distance relay. Considering the fact that the optimization problem is nonlinear and non-convex, the particle swarm optimization (PSO) is used to solve this problem. The proposed optimization problem is applied on a 9-bus network, and the reach settings of distance relays are calculated and compared with those of the conventional approach. Also, uncertainties are prioritized based on the amount of their impact on the probabilistic indices of sensitivity and selectivity.U ovom radu je problem određivanja dosega zona udaljenih releja uz stohastičko modeliranje neodređenosti predstavljen kao novi optimizacijski problem. S tim u vezi, neodređenosti su modelirane na osnovu njihovih funkcija gustoće vjerojatnosti. Potom je korištenjem Monte-Carlo procesa dobivena impedancija koju vidi udaljeni relej. U ovom radu su definirani indeksi stohastičke osjetljivosti i selektivnosti za svaku zonu udaljenog releja. Problem određivanja optimalnog dosega udaljenog releja za svaku zonu je transformiran u optimizacijski problem s kriterijem maksimiziranja stohastičkih indeksa ostjetljivosti i selektivnosti. Kriterijska funkcija i ograničenja optimizacijskog problema definirani su na osnovu strategije zaštite svake od tri različite zone udaljenog releja. Uzimajući u obzir da je dobiveni optimizacijski problem nelinearan i nekonveksan, za dobivanje rješenja je u radu korištena optimizacija rojem čestica. Predloženi optimizacijski problem primijenjen je na mrežu s 9 sabirnica, pri čemu je izračunati doseg udaljenih releja uspoređen s konvencionalnim pristupom. Također, prioritet neodređenosti određen je na osnovu njihovog utjecaja na stohastičke indekse osjetljivosti i selektivnosti

Transcranial Direct Current Stimulation Combining Mindfulness Based Relapse Prevention for Smoking Cessation: A Case Report

Previous electroencephalography (EEG) researches have shown significant differences in terms of abnormal brain activity among smokers and non-smokers. Typically, EEG analysis showed decreased slow waves and increased fast waves in people with nicotine consumption. The present study tested a transcranial direct current stimulation (tDCS) technique combined with Mindfulness-Based Relapse Prevention (MBRP) to reduce nicotine cravings. Specifically, cathodal tDCS over Left Prefrontal Cortex (PFC), as well as anodal stimulation over the right central zone, tested. An 18-year-old right-handed male with almost three years of smoking participated. He had no anti-tobacco medical prescription. The participant received twelve sessions of tDCS treatment (two times a week). Anodal stimulation (1.5 mA, 15 min) performed on C3 (LORETA source localization) and cathodal stimulation on FP2. Also, the participant received 30-minute MBRP-based psychotherapy sessions in order to ameliorate aggression, stress, and craving. Clinical evaluations, Buss-Perry Aggression Questionnaire (AGQ), Fagerstrom Test for Nicotine Dependence (FTND), Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1994), and daily checklist for the number of smoked cigarettes administered along with Carbon monoxide (CO) levels. Also, subjective measures of craving intensity between zero and ten measured after treatment and 3-month follow-up. After treatment, the participant showed a substantial reduction in all clinical tests, and the number of cigarettes decreased from 30 to 2 a day. From a psycho neurotherapeutic perspective, the present study provides preliminary indications for a novel and efficient treatment of smoking during adolescence. Further studies are needed to determine generalizability and overall efficiency

Choroidal Thickness and Hemoglobin A1c Levels in Patients with Type 2 Diabetes Mellitus

Purpose: The aim of this study was to assess the correlation of hemoglobin A1c (HbA1c) levels with choroidal thickness in patients with type 2 diabetes mellitus (DM) using spectral domain optical coherence tomography (SD-OCT). Methods: In this prospective case series, 180 eyes from 90 patients with type 2 DM were classified into three study groups based on HbA1c values: group 1 included patients with good glycemic control (HbA1c ≤ 7%), group 2 included patients with moderate glycemic control (HbA1c between 7% and 8%), and group 3 included patients with poor glycemic control (HbA1c ≥ 8%). Additionally, 50 eyes from 25 non-diabetic subjects were enrolled to group 4 as a control group. Sub-foveal, nasal, and temporal choroidal thickness were measured and compared. Results: Mean central, nasal, and temporal choroidal thicknesses in diabetic patients (247.80, 238.63, and 239.30 μm) were significantly less than non-diabetic healthy subjects (277.56, 262.92, and 266.32 μm). Additionally, mean central, nasal, and temporal choroidal thickness values in group 4 (277.56, 262.92, and 266.32 μm) were significantly greater than the corresponding values in group 2 (248.34, 237.55, and 236.45 μm) and group 3 (239.81, 234.62, and 233.94 μm), but was not significantly different from corresponding values in group 1 (259.46, 246.12, and 251.00 μm). Conclusion: HbA1c values have a significant correlation with choroidal thickness in diabetic patients, and better glycemic control with HbA1c ≤ 7% may prevent choroidal thinning

An Idiopathic Thrombocytopenic Purpura Patient Treated With Homeopathy: A Case Report

Introduction: Homeopathy can be applied to treat various diseases and conditions such as cancer, allergy, mood disorders, headache and pain. This case showed that homeopathic medicine can be a treatment modality for idiopathic thrombocytopenic purpura (ITP), an autoimmune-mediated hematologic disorder. Case Presentation: The patient was a 5.5–year-old child with ITP who referred to the homeopathic clinic with extensive petechiae and purpura on her body. Her platelet count was 15000/mcL and her anti-dsDNA and ANA were negative on her first visit. Her disease had first been diagnosed at the age of 2.5 years. She had undergone routine therapy for ITP; however, despite 15 months of corticosteroid therapy and IVIG injections, her platelet count was still low. After treatment with homeopathic remedies, her platelet count increased and signs of ITP disappeared. Conclusion: Homeopathic remedies can be considered as complementary and alternative medicines for ITP treatment protocols
