A LCX-Based Intrusion-Detection Sensor Using a Broadband Noise Signal

An intrusion detection sensor system based on a broadband noise signal and two leaky coaxial cables (LCXs) is proposed and experimentally demonstrated. In the proposed sensor, the broadband noise signal is generated by our designed white noise generator used as the detection signal. The detection signal is transmitted and received by two parallel LCXs, forming an invisible electromagnetic monitoring field around the protected area. The intrusion distance along the LCXs can be accurately extracted by the correlation method and the difference between pre- and post-intrusion correlation curves. Experimental results demonstrate the proposed sensor can monitor the intrusion process and locate multiple intruders. The range resolution of 30 cm and the dynamic range of 30 dB can be achieved. Furthermore, the proposed sensor has the strong anti-radio frequency interference (anti-RFI) capability, which makes it very suitable in the complex RF environment.
Validation of Highly Accelerated Wave–CAIPI SWI Compared with Conventional SWI and T2*-Weighted Gradient Recalled-Echo for Routine Clinical Brain MRI at 3T

BACKGROUND AND PURPOSE: SWI is valuable for characterization of intracranial hemorrhage and mineralization but has long acquisition times. We compared a highly accelerated wave–controlled aliasing in parallel imaging (CAIPI) SWI sequence with 2 commonly used alternatives, standard SWI and T2*-weighted gradient recalled-echo (T2*W GRE), for routine clinical brain imaging at 3T. MATERIALS AND METHODS: A total of 246 consecutive adult patients were prospectively evaluated using a conventional SWI or T2*W GRE sequence and an optimized wave–CAIPI SWI sequence, which was 3–5 times faster than the standard sequence. Two blinded radiologists scored each sequence for the presence of hemorrhage, the number of microhemorrhages, and severity of motion artifacts. Wave–CAIPI SWI was then evaluated in head-to-head comparison with the conventional sequences for visualization of pathology, artifacts, and overall diagnostic quality. Forced-choice comparisons were used for all scores. Wave–CAIPI SWI was tested for superiority relative to T2*W GRE and for noninferiority relative to standard SWI using a 15% noninferiority margin. RESULTS: Compared with T2*W GRE, wave–CAIPI SWI detected hemorrhages in more cases (P < .001) and detected more microhemorrhages (P < .001). Wave–CAIPI SWI was superior to T2*W GRE for visualization of pathology, artifacts, and overall diagnostic quality (all P < .001). Compared with standard SWI, wave–CAIPI SWI showed no difference in the presence or number of hemorrhages identified. Wave–CAIPI SWI was noninferior to standard SWI for the visualization of pathology (P < .001), artifacts (P < .01), and overall diagnostic quality (P < .01). Motion was less severe with wave–CAIPI SWI than with standard SWI (P < .01). CONCLUSIONS: Wave–CAIPI SWI provided superior visualization of pathology and overall diagnostic quality compared with T2*W GRE and was noninferior to standard SWI with reduced scan times and reduced motion artifacts.
Student and Faculty Views of Important Elements of Teaching in Associate Level Allied Health Programs

Teaching requires constant adapting, and need to continually reflect, and be ready to make changes when teaching elements may not prove effective. The purpose of this study was to examine faculty and student views of effective elements of teaching in an associate level allied health program. Surveys were collected from associate degree seeking allied health students and full-time faculty currently employed at a technical college in the northeastern region of the state of Georgia. The results showed a high confidence level with little to no difference in mean confidence levels between faculty and student responses on 15 Likert-scaled questions. Two open-ended questions showed little difference as well with faculty and students having similar responses when asked their preferred teaching/learning method. Results of this study will help to improve educational instruction for allied health programs. 3 DEDICATION I would like to dedicate this thesis to my family, and friends.

Simulating Behavioral Influences on Community Flood Risk under Future Climate Scenarios

Flood risk is a function of both climate and human behavior, including individual and societal actions. For this reason, there is a need to incorporate both human and climatic components in models of flood risk. This study simulates behavioral influences on the evolution of community flood risk under different future climate scenarios using an agent‐based model (ABM). The objective is to understand better the ways, sometimes unexpected, that human behavior, stochastic floods, and community interventions interact to influence the evolution of flood risk. One historic climate scenario and three future climate scenarios are simulated using a case study location in Fargo, North Dakota. Individual agents can mitigate flood risk via household mitigation or by moving, based on decision rules that consider risk perception and coping perception. The community can mitigate or disseminate information to reduce flood risk. Results show that agent behavior and community action have a significant impact on the evolution of flood risk under different climate scenarios. In all scenarios, individual and community action generally result in a decline in damages over time. In a lower flood risk scenario, the decline is primarily due to agent mitigation, while in a high flood risk scenario, community mitigation and agent relocation are primary drivers of the decline. Adaptive behaviors offset some of the increase in flood risk associated with climate change, and under an extreme climate scenario, our model indicates that many agents relocate.
Upregulation of smooth muscle Rho-kinase protein expression in human asthma

The lack of bronchodilatory response to deep inspiration in asthmatics is thought to be partially due to reduced airway distensibility [1, 2], possibly caused by an increase in airway smooth muscle (ASM) tone and stiffness [3]. Rho-kinase (ROCK) is known to play a role in regulating ASM tone [4] and ASM cytoskeletal stiffness [5]. An important phenotypic change is associated with human asthma: the protein expression of both isoforms of Rho-kinase, ROCK1 and ROCK2, is increased in the smooth muscles of intra-parenchymal airways and in the pulmonary blood vessels http://bit.ly/2pPfyxH
Development of High-Performance Detector Technology for UV and IR Applications

Sensing and imaging for ultraviolet (UV) and infrared (IR) bands has many applications for NASA, defense, and commercial systems. Recent work has involved developing UV avalanche photodiode (UV-APD) arrays with high gain for high resolution imaging. Various GaN/AlGaN p-i-n UV-APDs have been fabricated from epitaxial structures grown by metal-organic chemical vapor deposition (MOCVD) on GaN substrates with avalanche gains greater than 5×105, and high responsivities. Similarly, the IR spectral band is useful for measuring ocean temperatures, atmospheric aerosols, forest fires, etc. We are also developing room temperature operating graphene-enhanced PbSe mid-wave infrared (MWIR) detectors and focal plane arrays (FPAs). These compact and low-cost MWIR sensors can benefit various NASA remote sensing applications. Here we present recent results from these high performance UV- and IR-band detector and FPA technologies.
Validation of the Postnatal Growth and Retinopathy of Prematurity Screening Criteria.

Importance The first Postnatal Growth and Retinopathy of Prematurity Study (G-ROP-1) developed new screening criteria with 100% sensitivity for type 1 retinopathy of prematurity (ROP) and 30% reduction of infants requiring examinations in a retrospective development cohort of 7483 infants from 29 North American hospitals in 2006-2012. Infants meeting 1 or more of the following criteria undergo examinations: gestational age less than 28 weeks or birth weight less than 1051 g; weight gain less than 120 g during age 10 to 19 days, weight gain less than 180 g during age 20 to 29 days, or weight gain less than 170 g during age 30 to 39 days; or hydrocephalus. Objective To evaluate the generalizability of the G-ROP screening criteria in a new cohort of at-risk infants. Design, Setting, and Participants This prospective validation cohort study (G-ROP-2) was conducted at 41 hospitals in the United States and Canada (25 G-ROP-1 hospitals and 16 new hospitals) from September 8, 2015, to June 13, 2017, among 3981 premature infants at risk for ROP and with known ROP outcomes. Main Outcomes and Measures Sensitivity for Early Treatment for Retinopathy of Prematurity Study type 1 ROP and potential reduction in infants receiving examinations. Results Among the 3981 infants in the study (1878 girls and 2103 boys; median gestational age, 28 weeks [range, 22-35 weeks]; median birth weight, 1072 g [range, 350-4080 g]; 1966 white; 942 black; 321 Latino; 120 Asian; 22 Native Hawaian or Pacific Islander; and 25 American Indian or Alaskan Native), the G-ROP criteria correctly predicted 219 of 219 cases of type 1 ROP (sensitivity, 100%; 95% CI, 98.3%-100%), while reducing the number of infants undergoing examinations by 35.6% (n = 1418). In a combined G-ROP-1 and G-ROP-2 cohort of 11 463 infants, the G-ROP criteria predicted 677 of 677 cases of type 1 ROP (sensitivity, 100%; 95% CI, 99.4%-100%), reducing the number of infants receiving examinations by 32.5% (n = 3730), while current criteria (birth weight <1501 g or gestational age ≤30 weeks 0 days) predicted 674 of 677 type 1 cases (sensitivity, 99.6%; 95% CI, 98.7%-99.8%). Conclusions and Relevance This study found that the G-ROP screening criteria were generalizable on validation and, if used clinically in the United States and Canada, could reduce the number of infants receiving examinations. The large G-ROP cohorts provide evidence-based screening criteria that have higher sensitivity and higher specificity (fewer infants receiving examinations) for type 1 ROP than currently recommended guidelines.
Rehabilitation during intensive treatment of acute leukaemia including allogenic stem cell transplantation: a qualitative study of patient experiences

Objectives The diagnosis and treatment of acute leukaemia (AL) affect physical, psychosocial and existential functioning. Long-lasting treatment periods with impaired immune system, hygienic and social restrictions challenge patient well-being and rehabilitation as compared with other individuals with cancer. This study elucidates how AL patients, treated with curative intent in an outpatient setting, assess their physical, psychosocial and existential capability during and following treatment, and furthermore reports on the health initiatives offered to support their rehabilitation. Design, setting, participants and interventions We conducted qualitative, semi-structured individual interviews with 16 AL patients, 6 months after end of treatment in the patients’ homes. This was the final interview, in a line of three, carried out as part of a larger qualitative study. Results The data were analysed thematically through an inductive ongoing process consisting of four steps. The final step, selective coding, resulted in the three categories: physical activity, mental well-being and social activity. None of the patients were satisfied with their physical capability at the time of interview and experienced substantial impairment of functional capabilities. All patients struggled with anxiety and expressed a need for continuous progress in treatment and well-being to feel safe. It took an unexpected large effort to regain a meaningful social life, and patients still had to prioritise activities. Conclusions AL patients suffered physically, psychologically and existentially throughout their illness trajectory. Rehabilitation initiatives deriving from the healthcare system and municipalities held room for improvement. Future programmes should pay attention to the contextual changes of treatment of this patient group and individuals’ changing needs and motivation of physical exercise.
No substantial change in the balance between model-free and model-based control via training on the two-step task

Human decisions can be habitual or goal-directed, also known as model-free (MF) or model-based (MB) control. Previous work suggests that the balance between the two decision systems is impaired in psychiatric disorders such as compulsion and addiction, via overreliance on MF control. However, little is known whether the balance can be altered through task training. Here, 20 healthy participants performed a well-established two-step task that differentiates MB from MF control, across five training sessions. We used computational modelling and functional near-infrared spectroscopy to assess changes in decision-making and brain hemodynamic over time. Mixed-effects modelling revealed overall no substantial changes in MF and MB behavior across training. Although our behavioral and brain findings show task-induced changes in learning rates, these parameters have no direct relation to either MF or MB control or the balance between the two systems, and thus do not support the assumption of training effects on MF or MB strategies. Our findings indicate that training on the two-step paradigm in its current form does not support a shift in the balance between MF and MB control. We discuss these results with respect to implications for restoring the balance between MF and MB control in psychiatric conditions.
Acute Effects of Immersive Virtual Reality Exercise on Young Adults’ Situational Motivation

The development of innovative technology, such as virtual reality (VR), has provided opportunities for promoting physical activity (PA) in a fun and engaging manner. The purpose of this study was to examine differences in young adults’ situational motivation (SM) among immersive VR, non-immersive VR, and traditional stationary cycling sessions. In all, 49 healthy college students (35 females; Mage = 23.6 years, SD = 3.4; M%BF = 24.0%, SD = 7.5) completed three separate 20 min cycling sessions: (1) immersive VR cycling; (2) non-immersive VR cycling; and (3) traditional cycling. Participants’ SM was assessed via the situational motivation scale, which included four subconstructs: intrinsic motivation, identified regulation, external regulation, and amotivation. Repeated measures ANOVAs indicated significant differences for situational motivation between cycling sessions (F (2, 96) = 4.74–53.04, p < 0.01, ηp2 = 0.090–0.525). Specifically, participants elicited the highest level of intrinsic motivation in immersive VR cycling compared to the other two sessions. Moreover, participants in both immersive VR and traditional cycling showed greater identified regulation than the non-immersive VR session. Furthermore, participants showed greater external regulation compared to the immersive VR session. In addition, greater amotivation was observed in non-immersive VR compared to the immersive VR session. Findings suggested that immersive VR exercise has the potential to be an attractive exercise alternative, possibly promoting greater PA participation and adherence among young adults.
Hepatitis E virus replication in human intestinal cells

Objective Hepatitis E virus (HEV), one of the most common agent of acute hepatitis worldwide, is mainly transmitted enterically, via contaminated water for HEV genotypes 1 (HEV1) and HEV2, or by eating raw or undercooked infected meat for HEV genotype 3 (HEV3) and HEV4. However, little is known about how the ingested HEV reaches the liver or its ability to replicate in intestinal cells. Design We developed human primary cultures of small intestine epithelial cells and intestinal explants obtained from small bowel resections. The epithelial cells were also polarised on transwells. Cells were infected with Kernow-p6 strain or clinically derived virions. Results Primary intestinal cells supported the growth of Kernow-p6 strain and HEV1 and HEV3 clinically derived virions. Polarised enterocytes infected with HEV1 and HEV3 strains released HEV particles vectorially: mostly into the apical compartment with a little basally. Iodixanol density gradient centrifugation of enterocyte-derived HEV virions gave bands at a density of 1.06–1.08 g/cm3, corresponding to that of quasi-enveloped HEV particles. Ribavirin therapy inhibited HEV excretion from the basal surface but not from the apical side of infected human enterocytes. HEV virions also infected intestinal tissue explants. Lastly, HEV RNA and antigen were detected in the intestinal crypts of a chronically infected patient. Conclusion HEV can replicate in intestinal cells and reaches the liver as quasi-enveloped virions.
Performance Evaluation of Query Response Time in The Document Stored NoSQL Database

NoSQL Database is one solution that can be used to store large amounts of data and have an excellent performance during the reading and writing process. Analysis of data with large volumes increasingly feels the benefits. Database exploration is one of the activities carried out in data analysis. Information on estimated response time queries can help in planning database exploration. This study aims to evaluate the response time of each query for the process of creating, read, update, delete (CRUD) on a document stored, NoSQL Database. MongoDB, ArangoDB, and CouchDB were selected for use in experiments. Experiments are carried out by processing queries for repeated create, read, update, and delete commands with different quantities. The experimental results in the study revealed that MongoDB had the lowest average query response time for the read process (0.017 seconds), update (25,358 seconds) and delete (0.055 seconds) compared to ArangoDB and CouchDB. However, for the creation process, the ArangoDB response time is the smallest, which is 28,493 seconds compared to MongoDB and CouchDB.
What Can Terrestrial Sand-Textured Soils Reveal About the Composition of Core Materials Forming Martian Regolithƒ

Reliable interpretations of remote sensing data obtained from Mars, notably in the visible and near-infrared spectral domains, need to correctly account for variations on the reflectance of the sand-textured regolith covering its surface. These variations, in turn, are directly associated not only with the presence of iron oxides, which are also found in dune fields and coastal landscapes on Earth, but also with the composition of the core (parent) material forming different types of Martian regolith. While the core materials of terrestrial sand-textured soils can be clearly identified, the same cannot be said about the core materials of Martian regolith. The difficulties to solve this open question are mainly prompted by the relatively restricted range of experiments that can be performed using equipment deployed on Mars. In fact, missions have been proposed to overcome these restrictions by collecting and bringing samples of Martian soils to Earth. In the meantime, the pairing of remote sensing technology with in silico experiments continues to play a key role in investigations of Martian geomorphology, mineralogy and weathering history. Following this trend, we have compared the effects of different types of core materials on the reflectance of Martian regolith in order to add to the current knowledge about its composition. The core material candidates were selected based on remote and in situ observations of terrestrial and Martian sand-textured soils. Our in silico experiments were performed using a first-principles simulation framework in conjunction with measured reflectance data obtained from different regions on Mars. Besides contributing to the elucidation of the problem at hand, our findings enable an original and predictive assessment of the impact of different core materials on the spectral signatures of terrestrial and non-terrestrial sand-textured soils.
