Shaping Interference Towards Optimality of Modern Wireless Communication Transceivers

A communication is impulsive whenever the information-bearing signal is burst-like in time. Examples of the impulsive concept are: impulse-radio signals, that is, wireless signals occurring within short intervals of time; optical signals conveyed by photons; speech signals represented by sound pressure variations; pulse-position modulated electrical signals; a sequence of arrival/departure events in a queue; neural spike trains in the brain. Understanding impulsive communications requires to identify what is peculiar to this transmission paradigm, that is, different from traditional continuous communications.In order to address the problem of understanding impulsive vs. non-impulsive communications, the framework of investigation must include the following aspects: the different interference statistics directly following from the impulsive signal structure; the different interaction of the impulsive signal with the physical medium; the actual possibility for impulsive communications of coding information into the time structure, relaxing the implicit assumption made in continuous transmissions that time is a mere support. This thesis partially addresses a few of the above issues, and draws future lines of investigation. In particular, we studied: multiple access channels where each user adopts time-hopping spread-spectrum; systems using a specific prefilter at the transmitter side, namely the transmit matched filter (also known as time reversal), particularly suited for ultrawide bandwidhts; the distribution function of interference for impulsive systems in several different settings.
The Impact of an Acute Medical Unit in Internal Medicine on Resident Education

Background Medical trainees are expected to provide care for increasingly sick and treatment intensive patients. To improve patient care, hospitals worldwide have developed acute medical units (AMUs), dedicated medical wards that provide care for patients during the first 24 to 72 hours of an emergency medical hospital admission. A distinguishing feature of these units is that they are supervised by senior clinicians and offer multidisciplinary patient-centered care. Little is known about the impact of AMUs on trainee supervision and education. Methods In this educational case study, we describe the evolution, process and structure of our AMU service. We also provide resident and teaching faculty perceptions of the impact of this intervention on education and supervision. Results Questionnaire results showed that residents and teaching attendings believed that supervision and education were improved on the AMU, as compared to the traditional medical ward model. Residents also felt that their knowledge and clinical skills in managing acute patients improved. Procedure skills were less impacted by the intervention. A small number of residents believed that the AMU model worsened supervision and education. Conclusion Integrating medical trainees into an AMU allowed for early evaluation and input from senior clinicians and increased opportunities to work in and learn from multidisciplinary teams, contributing to improved resident supervision and education. Future studies are needed to assess the long-term impact of the AMU on educational outcomes.
Structural and Evolutionary Adaptations of Nei-Like DNA Glycosylases Proteins Involved in Base Excision Repair of Oxidative DNA Damage in Vertebrates

Oxidative stress is a type of stress that damages DNA and can occur from both endogenous and exogenous sources. Damage to DNA caused by oxidative stress can result in base modifications that promote replication errors and the formation of sites of base loss, which pose unique challenges to the preservation of genomic integrity. However, the adaptive evolution of the DNA repair mechanism is poorly understood in vertebrates. This research aimed to explore the evolutionary relationships, physicochemical characteristics, and comparative genomic analysis of the Nei-like glycosylase gene family involved in DNA base repair in the vertebrates. The genomic sequences of NEIL1, NEIL2, and NEIL3 genes were aligned to observe selection constraints in the genes, which were relatively low conserved across vertebrate species. The positive selection signals were identified in these genes across the vertebrate lineages. We identified that only about 2.7% of codons in these genes were subjected to positive selection. We also revealed that positive selection pressure was increased in the Fapy-DNA-glyco and H2TH domain, which are involved in the base excision repair of DNA that has been damaged by oxidative stress. Gene structure, motif, and conserved domain analysis indicated that the Nei-like glycosylase genes in mammals and avians are evolutionarily low conserved compared to other glycosylase genes in other “vertebrates” species. This study revealed that adaptive selection played a critical role in the evolution of Nei-like glycosylase in vertebrate species. Systematic comparative genome analyses will give key insights to elucidate the links between DNA repair and the development of lifespan in various organisms as more diverse vertebrate genome sequences become accessible.
Delinquency Behaviors and Substance Use of Youth Exposed to the keepin’ it REAL Substance Use Prevention Program

Introduction : Guided by problem behavior theory, this study examined the clustering of substance use and delinquency among early adolescents. Using longitudinal data, we also examined the effects of the Social and Emotional Learning (SEL)-based intervention keepin’ it REAL (kiR) on class membership and transitions over time. Methods : A total of 3,921 seventh graders (51% male) participated in a randomized clinical trial conducted in the Midwest and middle Atlantic regions of the U.S. We assessed past-month substance use and past-year delinquency at baseline (beginning of 7 th grade) and 2 follow-up periods (end of 8 th and 9 th grades). Results : Latent transition analysis identified four statuses across control and treatment conditions: Mild-Moderate Delinquency Behavior (MDB), Polysubstance Use + Moderate-Severe Delinquency Behaviors (PDB), Alcohol Use (AU), and No Risk (NR). Youth in the PDB status at Time 1 receiving the kiR intervention were more likely to transition to the NR status at Time 3 compared with the same status in the control condition. Furthermore, youth in the AU status at Time 3 exposed to kiR were less likely to transition to the PDB status at Time 4 compared with the same status in the control condition. Conclusion : Youth may benefit from exposure to SEL programs, such as kiR, which shows promise for reducing dual presenting problems (polysubstance use and delinquency) among higher-risk early adolescents (the PDB status). Further research should explore why and how kiR influences certain status at different time points.

Objective The present study aims to explore potential infection and death risk factors in patients infected with carbapenem-resistant Klebsiella pneumoniae (CRKP). Methods A retrospective case-control study was performed at Beijing Shijitan Hospital, China. The clinical and microbiological data of patients infected with K. pneumoniae (K.pn) were collected; the clinical characteristics of patients infected with carbapenem-susceptible K.pn and CRKP were analyzed using logistic regression analysis. Results CRKP infection was significantly associated with prior carbapenem use (odds ratio [OR] and 95% credibility interval [CI]: 5.161 [1.840–32.233], P < 0.001), the use of more than three types of antibiotics for seven or more days (OR and 95% CI: 9.681 [2.662–18.122], P < 0.001), tracheotomy (OR and 95% CI: 5.015 [2.343–11.724], P < 0.001), and intensive care unit (ICU) stay (OR and 95% CI: 6.322 [2.02–12.231], P < 0.001). The risk of death in patients with CRKP infection was significantly associated with older age (OR and 95% CI of 70–80 years: 8.894 [1.972–67.346], P < 0.001; ≥80 years: 15.234 [2.072–93.452], P < 0.001), renal dysfunction (OR and 95% CI: 1.672 [1.104–7.451], P = 0.016), tracheotomy (OR and 95% CI: 2.051 [1.217–11.235], P = 0.002), and ICU stay (OR and 95% CI: 3.043 [2.174–18.453], P < 0.001). Conclusion Prior to carbapenem use, older age, renal dysfunction, tracheotomy, and ICU stay were independent risk factors for death in patients infected with CRKP.

Adaptive Fuzzy Control of Nonlinear Systems With Function Constraints Based on Time-Varying IBLFs

In this article, an adaptive tracking control approach is developed for a class of strict-feedback nonlinear systems with time-varying full state constraints. As a breakthrough in this system, the special function constraints (whose constraint boundary is relevant to both state variables and time) are considered, which are rarely studied by research work. And there is no doubt that this method increases the complexity of designing this scheme. Furthermore, the time-varying integral barrier Lyapunov functions combining with backstepping technique is introduced to break the limitation of traditional methods as well as achieve the full state constraints. Meanwhile, fuzzy logic systems are selected to approximate unknown nonlinear functions. It is verified that all closed-loop signals are bounded and all states are forced in the time-varying boundness. In addition, the proposed control strategy has a good performance. The effectiveness of the theoretical analysis results is proved via a simulation example.

Morphology of Glenoid Cartilage Defects in Anteroinferior Glenohumeral Instability

Background: Glenoid cartilage defects may contribute to anterior shoulder instability recurrence and progression to osteoarthritis, but their morphology remains unknown. Purpose/Hypothesis: The purpose was to determine the shape, size, and location of glenoid cartilage defects and the prevalence and risk factors for cartilage defects in the setting of anterior glenohumeral instability. It was hypothesized that glenoid cartilage defects would be common, would be associated with recurrence of dislocation, and would share similar morphology with glenoid osseous defects. Study Design: Cross-sectional study; Level of evidence, 3. Methods: In this retrospective study, all patients who underwent arthroscopic surgical treatment for anterior glenohumeral instability between January 2012 and May 2019 were included; excluded were patients with documented posterior or multidirectional instability or previous glenohumeral surgery. For each patient, the operative report, arthroscopic images, and preoperative magnetic resonance imaging (MRI) scans were reviewed to determine the prevalence of cartilage injury. For those patients with an Outerbridge grade 3 or 4 defect, the cartilage surfaces on the MRI scans were segmented to make 3-dimensional (3-D) segmentations. From these 3-D segmentations, we measured length, width, and surface area of the glenoid and defect, and the orientation of the defect relative to the superior and inferior poles of the glenoid. A multivariable analysis was conducted to determine correlates with cartilage damage. Results: In 322 patients treated operatively for anterior glenohumeral instability, 38% had a concomitant cartilage defect. The mean cartilage defect was located directly anteriorly at the 3:07 clockface position (range, 2:10-4:05) and encompassed 6.5% ± 3.5% of the glenoid surface area. However, defects ranged up to >56% of glenoid length and up to 27% of glenoid width, and the largest defect encompassed 19.5% of the glenoid cartilage surface area. Patients with a cartilage defect were more likely to be male (P = .031) and to have undergone a concomitant posterior labral repair (P = .018). Conclusion: Cartilage defects were common in patients with operatively treated anterior glenohumeral instability, occurring in 38% of patients. These defects were located directly anteriorly at 3:07, similar to osseous glenoid defects. Future prospective studies with cartilage-specific MRI sequences should be conducted.

Modeling of Magnetic Fields in Deformed Air Gaps of Salient Pole Synchronous Machines

Large low-speed drives are designed with a high number of pole pairs, annular and magnetically saturated at rated operation. Large bore diameters tend to unwanted deformations of circular air gap (AG) circumference due to magnetic forces or gravitational forces. The electromagnetic computation with changing geometrical conditions therefore poses a cumbersome non-linear field problem due to its high amount of degrees of freedom. For an accurate predictive model of machine acoustics and vibrations, the study of these topological impacts on the magnetic AG field is indispensable. Particularly when considering an arbitrary AG deformation, related to additional spatial flux harmonics, the computational chain of the finite element method (FEM) involves adaptations at each stage (pre- and post-processing). The proposed modeling approach is universal and reduces the computational effort significantly using finite element (FE) solutions of symmetrical machine parts with varying AG widths. 2-D FE simulations are performed to study the impact of deformations. The results of the approach are compared with FE solutions of a complete 2-D model with an exemplary deformation for validation. The aim of this work is to study both magnetic AG fields and forces efficiently in an exemplary high-pole wind turbine generator with a deformed AG topology by interpolating and assembling appropriately partial model solutions.
Distributed Multidisciplinary Optimization of a Turbine Blade Regarding Performance, Reliability and Castability

Modern aero-engine blades are optimized for high perfor- mance and long service life, but manufacturing requirements are not considered adequately during the design process. Thus, time- consuming, iterative re-designs become necessary until a pro- ducible component evolves. The multidisciplinary design opti- mization method presented in this paper addresses not only the aerodynamic efficiency and structural reliability of a new turbine blade, but also ensures the castability of the design and thereby accelerates the entire design process and reduces the time-to- production. Because real casting process simulations are very time-intensive, they were substituted by checks of experimentally and numerically validated geometrical constraints. Different engineering tools were assembled in a joint process chain using an integration framework, which manages and distributes the calculations and hence the workload in a shared network. Based on a preliminary design of a new turbine section, the selected initial low pressure turbine blade was neither castable nor reliable. The multidisciplinary optimization achieved a blade design that satisfies the requirements for a successful casting process, has a low failure probability and, although not as high as from a pure aerodynamic optimization, exhibits an efficiency improvement.

Additionally, a method for the analysis of SMC parts with radar measurement methods in the Gigahertz area is introduced. The hereby considered parameters are the fiber orientation, fiber volume content, and quality failures like welding lines as they are crucial for the mechanical properties of the material. The methods presented are already in use in the automotive industry for quality assurance of radar covers and show potential as a fast and non-destructive method to analyse those important material parameters of SMC components.
The Frequency of Epidermal Growth Factor Receptor (EGFR) Mutation in Patients with Lung Adenocarcinoma Referred to a Lung Diseases Hospital; A Cross-Sectional Study from Iran

Background & Objective: Various studies showed the use of epidermal growth factor receptors (EGFRs) gene mutations in the therapeutic plan of patients with advanced lung cancer. This study aimed to investigate the frequency and types of EGFR gene mutations among Iranian patients with lung adenocarcinoma referred to a specialized lung diseases hospital from 2014 to 2019. Methods: The data of all patients with lung adenocarcinoma referred to the Molecular Department of Masih Daneshvari Hospital Laboratory (National Research Institute of Tuberculosis and Lung Diseases) from 2014 to 2019 for EGFR mutation tests were collected. Patients' characteristics data and information on the frequency and types of EGFR gene mutations were obtained from the hospital information system (HIS). The collected data were analyzed using SPSS 25. Results: A total of 570 individuals (Mean age of 58.74, 51.6% Male) were included in the study; 113 out of 570 patients (19.8%) were diagnosed with gene mutation. In terms of the type of mutation, 65 participants (57%) showed deletion, 48 patients (42.1%) were diagnosed with replacement, and one (0.9%) case demonstrated both. Notably, the mutation rate detected among the female patients was significantly higher than the male ones (P=0.001); in particular, deletion type of mutation was found more among women, although both genders were the same in terms of the replacement frequency. However, the age had no effect on the mutation in this study (P=0.05). Conclusion: Among Iranian patients with lung adenocarcinoma, 19.8% harbored EGFR gene mutation. This mutation was found in association with lung cancer and could affect the patient's therapeutic plan.
