The automatic stealth task of military time-sensitive targets plays a crucial role in maintaining national military security and mastering battlefield dynamics in military applications.We propose a novel Military Time-sensitive Targets Stealth Network via Real-time Mask Generation(MTTSNet).According to our knowledge,this is the first technology to automatically remove military targets in real-time from videos.The critical steps of MTTSNet are as follows:First,we designed a real-time mask generation network based on the encoder-decoder framework,combined with the domain expansion structure,to effectively extract mask images.Specifically,the ASPP structure in the encoder could achieve advanced semantic feature fusion.The decoder stacked high-dimensional information with low-dimensional information to obtain an effective mask layer.Subsequently,the domain expansion module guided the adaptive expansion of mask images.Second,a context adversarial generation network based on gated convolution was constructed to achieve background restoration of mask positions in the original image.In addition,our method worked in an end-to-end manner.A particular semantic segmentation dataset for military time-sensitive targets has been constructed,called the Military Time-sensitive Target Masking Dataset(MTMD).The MTMD dataset experiment successfully demonstrated that this method could create a mask that completely occludes the target and that the target could be hidden in real time using this mask.We demonstrated the concealment performance of our proposed method by comparing it to a number of well-known and highly optimized baselines. 展开更多

One of the major challenges arising in internet of military things(IoMT)is accommodating massive connectivity while providing guaranteed quality of service(QoS)in terms of ultra-high reliability.In this regard,this paper presents a class of code-domain nonorthogonal multiple accesses(NOMAs)for uplink ultra reliable networking of massive IoMT based on tactical datalink such as Link-16 and joint tactical information distribution system(JTIDS).In the considered scenario,a satellite equipped with Nr antennas servers K devices including vehicles,drones,ships,sensors,handset radios,etc.Nonorthogonal coded modulation,a special form of multiple input multiple output(MIMO)-NOMA is proposed.The discussion starts with evaluating the output signal to interference-plus-noise(SINR)of receiver filter,leading to the unveiling of a closed-form expression for overloading systems as the number of users is significantly larger than the number of devices admitted such that massive connectivity is rendered.The expression allows for the development of simple yet successful interference suppression based on power allocation and phase shaping techniques that maximizes the sum rate since it is equivalent to fixed-point programming as can be proved.The proposed design is exemplified by nonlinear modulation schemes such as minimum shift keying(MSK)and Gaussian MSK(GMSK),two pivotal modulation formats in IoMT standards such as Link-16 and JITDS.Numerical results show that near capacity performance is offered.Fortunately,the performance is obtained using simple forward error corrections(FECs)of higher coding rate than existing schemes do,while the transmit power is reduced by 6 dB.The proposed design finds wide applications not only in IoMT but also in deep space communications,where ultra reliability and massive connectivity is a keen concern. 展开更多

Background: Military medicine cadets undergo strenuous military training alongside demanding medical studies. This stressful and complex educational environment can lead to the emergence of depressive symptoms. We investigated the prevalence of depressive symptoms in a cohort of military medicine cadets.Methods: We conducted a descriptive questionnaire-based cross-sectional study among Greek military medicine cadets in the undergraduate program of the Hellenic Military School of Combat Support Officers. The Greek translation of the Zung self-rating depression scale questionnaire was used to screen for the presence of depressive symptoms. In addition, demographic, academic and dietary information was collected. The Shapiro-Wilk test of normality, Pearson correlation test, Chi-square test, t-test and Mann Whitney U test were employed for statistical analysis.Results: We enrolled 55 female and 91 male military medicine cadets with a mean age of 19.84 years(SD=0.99). The mean Zung crude score was 43.32(SD=4.55): 42.8(SD=4.43) for female cadets and 43.64(SD=4.6) for male cadets. Cadets were further subdivided into low and high risk groups for the presence of depressive symptoms. We identified 57(39%) cadets with a total Zung crude score of 45 or above: 21 females and 36 males. Statistical analysis did not reveal any significant differences between the two groups based on gender, year of training, academic performance, alcohol consumption, smoking status, vitamin supplementation, dietary habits or BMI.Conclusion: We report a high prevalence of depressive symptoms in a cohort of military medicine cadets that underscores the need for effective screening and appropriate and timely interventions. We did not identify any related risk factors. Military medicine cadets are exposed to a challenging military and medical training environment, and thus represent a group at risk for development of depression. 展开更多

The paper discusses minimizing the effect of external mechanical vibration on hydraulic valves in different military hydraulic drive systems.The current research work presents an analysis of the potential to reduce vibration on the valve casing by installing a valve flexibly on a vibrating surface,i.e.,by introducing a material with known stiffness and damping characteristics between the valve casing and the vibrating surface-a steel spring package or special cushions made of elastomer material or of oilresistant rubber.The article also demonstrates that elastomer cushions placed inside the valve casingbetween the casing and the centering springs-can be used as a supplementary or alternative solution in the analyzed method for mitigating the transfer of vibrations.By using materials with appropriately selected elastic and dissipative properties,the effectiveness of vibro-isolation can be increased.The presented theoretical analyzes by linear and non-linear mathematical models have been verified experimentally. 展开更多

Owing to the ubiquitous use of smartphones by soldiers, military researchers have an increasing interest in potentially problematicside effects such as smartphone overdependence. This raises a question regarding the psychological mechanisms underlying thepotentially self-damaging use of smartphones. Here, we address this question by analyzing how heterogeneity in commander’sgood leadership explains subordinate soldiers’ differences in self-control and smartphone use. Specifically, we found thatsubordinate soldiers who thought their commander's leadership was good were self-regulated, less dependent on smartphones,less stressed, and finally had good mental health. This result indicates that commander’s good leadership can be used toestimate whether subordinate soldiers exert control over their impulses and use their smartphones properly. Thus, the currentfindings help to identify external factors that lead to a better understanding of problematic smartphone use and can potentiallyhelp to design appropriate preventive mechanisms or interventions that target commander’s good leadership. 展开更多

Introduction: In December 2021, Beninese soldiers were victims of armed terrorist attacks. This study aims to determine the psychological impact of the events experienced on the victims in order to better prevent post-traumatic stress disorder. Materials and methods: This is a descriptive cross-sectional study conducted from December 13 to 14, 2021, i.e. 12 days after the oldest event and 4 days after the most recent. The experience of the event was assessed with the Peritraumatic Distress Inventory and the Peritraumatic Dissociation Experiences Questionnaire. Symptoms experienced in the hours and days after the event were assessed with the Revised Event Impact Scale. Results: 36 soldiers were included out of the 38 survivors, i.e. 94.73%. They were 51.43% victims of the night assault, 37.14% of the ambush on patrol and 11.43% of the explosion of vehicle on mine, all male. The average age was 31 years with extremes of 25 and 49 years. The 25 - 30 year olds predominated, 52.78%. 100% of soldiers had significant peritraumatic dissociation, of which 94.44% also had significant peritraumatic distress. 100% of the soldiers had manifestations of intrusion, 89% of manifestations of avoidance and 83% of manifestations of hyperexcitation. 88.89% had an index for acute stress including 100% of victims of night assault and vehicle explosion on mine. Conclusion: This study shows a high prevalence of peritraumatic reactions, recognized factors favoring post-traumatic stress disorder, and the interest of their evaluation for medical and psychological help adapted to the victims. 展开更多

Background: Urological care has been advancing quickly over the last ten years in Benin. In order to conveniently support that trend towards better urological care standards, decision-makers need sound data on urological diseases in the country. Objective: To determine the prevalence of urological diseases in the former Military Teaching Hospital of Cotonou. Patients and Method: We retrospectively collected the urological diseases that the institution had managed from January 2012 to December 2020. We used Excel<sup>©</sup> 2010 and SPSS<sup>©</sup> to analyze the collected data. Results: 4244 patients, i.e. 3717 males (87.58%) and 527 females (12.42%) were managed during the study period. The main diseases diagnosed were benign prostatic hyperplasia (32.61%, n = 1384), erectile dysfunction (10.44%, n = 443), chronic prostatitis (5.94%, n = 252), prostate cancer (4.03%, n = 171), and ejaculatory disorders (3.44%, n = 146). In patients ≤ 15 years, predominant diseases were peritoneal vaginal canal (15.9%, n = 43), circumcision (15.6%, n = 42), testicular dystopia (10.7%, n = 29), hydrocele (7.8%, n = 21), and hypospadias (5.6%, n = 15). Wilms tumor (1.9%, n = 5) was the first cancer, testicular (0.4%, n = 1) and para-testicular (0.4%, n = 1) tumors were the next. In patients > 15 and ≤40 years, the main diseases were infertility (14.1%, n = 189), chronic prostatitis (12.9%, n = 173), erectile dysfunction (10.1%, n = 135), ejaculatory disorders (6.2%, n = 83), genital infections (6.2%, n = 83) and urinary stone (4.9%, n = 66). The first cancer was kidney cancer (0.97%, n = 13) followed by bladder cancer (0.3%, n = 4) and testicular tumor (0.3%, n = 4). In patients >40 years, the most prevalent diseases were BPH (52.0%, n = 1370), erectile dysfunction (11.7%, n = 308), prostate cancer (6.5%, n = 171), inguinal hernia (5.1%, n = 134), and urinary stone (3.9%, n = 102). Prostate cancer is the first cancer;the next were bladder (0.95%, n = 25) and kidney (0.68%, n = 18) cancers. Conclusion: Benign prostatic hyperplasia and urological cancers (prostate, bladder and kidney cancers) were the main urological diseases at the former Military Teaching Hospital of Cotonou. Urological malformations and Wilms tumor were the main diseases in the children. 展开更多
