Hierarchical Control of Aircraft Electro-Thermal Systems

A hierarchical model predictive control (MPC) approach is developed for energy management of aircraft electro-thermal systems. High-power electrical systems on board modern and future aircraft perform a variety of mission- and flight-critical tasks, while thermal management systems actively cool these electronics to satisfy component-specific temperature constraints, ensuring safe and reliable operation. In this paper, coordination of these electrical and thermal systems is performed using a hierarchical control approach that decomposes the multi-energy domain, constrained optimization problem into smaller, more computationally efficient problems that can be solved in real-time. A hardware-in-the-loop (HIL) experimental testbed is used to evaluate the proposed hierarchical MPC in comparison to a baseline controller for a scaled, laboratory representation of an aircraft electro-thermal system. Experimental results demonstrate that the proposed approach outperforms the baseline controller across a range of electrical loading in terms of both efficient energy management and constraint satisfaction.

Sebelum dilakukan terapi bekam, rata-rata tekanan darah sistolik adalah 152,50 mmHg dan rata-rata tekanan diastolik 85,25 mmHg. Sesudah terapi bekam diperoleh hasil bahwa rata-rata tekanan darah sistolik adalah 134,25 mmHg dan rata-rata tekanan diastolik 80 mmHg. Berdasarkan uji statistik diperoleh hasil p-value sebesar 0,000, artinya terdapat perbedaan tekanan darah sebelum dan setelah terapi bekam.
River islands as habitats for soil mites (Acari)

River islands are a natural element of fluvial river systems. They are the refuge of many species of plants and animals and of unchanged ecological systems. Due to their spatial isolation, river islands are good places to observe colonization processes of both flora and fauna (biota). The goal of our research was to observe the development of soil mite communities colonizing the river island. Mite communities on river islands are dominated by eurytopic species, which are r‐strategists, reproduce parthenogenetically, and can be dispersed either passively by the wind or actively by phoresis on insects, small mammals, or birds. The main factors limiting the diversity of acarofauna on river islands are floods (and the resulting soil moisture content of the environment) and spatial isolation. The fertility of the habitat (content of humus) is of less importance. The results of our research indicate that Oribatida are the most sensitive to frequent flooding and high soil moisture, and they were the least effective in colonizing the island. Among the species resistant to the above‐mentioned limiting factors were Cheiroseius borealis, Cheiroseius bryophillus, Cheiroseius curtipes, Liochthonius lapponicus, Punctoribates punctum, Arctoseius cetratus, Parasitus beta, Ameroseius corbicula, Oribatula tibialis, Tectocepheus velatus, and representatives of Acarididae, Pygmephoridae, Stigmeidae, and Tarsonemidae.
Identifying Key Target Audiences for Public Health Campaigns: Leveraging Machine Learning in the Case of Hookah Tobacco Smoking

Background Hookah tobacco smoking (HTS) is a particularly important issue for public health professionals to address owing to its prevalence and deleterious health effects. Social media sites can be a valuable tool for public health officials to conduct informational health campaigns. Current social media platforms provide researchers with opportunities to better identify and target specific audiences and even individuals. However, we are not aware of systematic research attempting to identify audiences with mixed or ambivalent views toward HTS. Objective The objective of this study was to (1) confirm previous research showing positively skewed HTS sentiment on Twitter using a larger dataset by leveraging machine learning techniques and (2) systematically identify individuals who exhibit mixed opinions about HTS via the Twitter platform and therefore represent key audiences for intervention. Methods We prospectively collected tweets related to HTS from January to June 2016. We double-coded sentiment for a subset of approximately 5000 randomly sampled tweets for sentiment toward HTS and used these data to train a machine learning classifier to assess the remaining approximately 556,000 HTS-related Twitter posts. Natural language processing software was used to extract linguistic features (ie, language-based covariates). The data were processed by machine learning tools and algorithms using R. Finally, we used the results to identify individuals who, because they had consistently posted both positive and negative content, might be ambivalent toward HTS and represent an ideal audience for intervention. Results There were 561,960 HTS-related tweets: 373,911 were classified as positive and 183,139 were classified as negative. A set of 12,861 users met a priori criteria indicating that they posted both positive and negative tweets about HTS. Conclusions Sentiment analysis can allow researchers to identify audience segments on social media that demonstrate ambiguity toward key public health issues, such as HTS, and therefore represent ideal populations for intervention. Using large social media datasets can help public health officials to preemptively identify specific audience segments that would be most receptive to targeted campaigns.
Homogeneity of 67P/Churyumov-Gerasimenko as seen by CONSERT: implication on composition and formation

Context. After the landing of Philae, CONSERT probed the nucleus of 67P/Churyumov-Gerasimenko (67P) and observed no heterogeneities at metric scale within the probed part of the small lobe of 67P. Further studies have then quantified the observed homogeneity in terms of maximum permittivity contrast versus the typical size of heterogeneities. Aims. The aim of this article is to interpret the sensitivity limits of CONSERT measurements in terms of composition, and to provide constraints on the maximum variability in composition, porosity, and local dust-to-ice ratio. Methods. The sensitivity of CONSERT measurements to local variations in density, dust-to-ice ratio, and composition was analyzed using permittivity modeling of mixtures. Results. We interpret the maximum detectable heterogeneity size and contrast in terms of composition and porosity of the nucleus. The sensitivity to porosity is ±10 percent points for heterogeneities with a characteristic length scale of a few meters; the sensitivity to local variations in the composition is limited. Conclusions. In terms of accretion, our results are compatible only with scenarios generating porosity heterogeneities at scales lower than one meter, or with porosity variations smaller than ±10 percent points. This is clearly compatible with an accretion model of a gentle gravitational collapse of a pebble cloud.
The Impact of Residential Life Hall Directors Becoming Hourly Employees in the Minnesota State University System

Live-on residential life hall director staff shifted from a salaried employment status to an hourly employment status as a result of a reinterpretation of the duties test of the Fair Labor Standards Act (FLSA) for these positions. Transitioning live-on residential life staff to hourly employment status occurred at institutions in the Minnesota State University System resulting in an unusual employment status for hall directors in the Minnesota State System compared to the national norm. Residence hall directors who became hourly employees served as the population of this basic qualitative study. The purpose was to explore the impact on worker performance resulting from the transition to hourly employment status. Blumberg and Pringle’s (1982) theory of worker performance served as the theoretical framework that guided this study. Kezar’s (2013) expansion of this theory of worker performance also contributed to the theoretical underpinning of this study. The narratives that emerged from this qualitative study provides context for future higher education leaders faced with the changing employment status of employees who have historically been salaried and then must transition to overtime-eligible status. Non-exempt (overtime-eligible) professionals in a higher education setting are likely confined to performing their duties in the context of a 40-hour workweek. The impact of this on professional residential life hall directors will be discussed.
Resampling and exchangeable arrays

The nonparametric, or resampling, bootstrap for a single unstructured sample corresponds to the algebraic operation of monoid composition, with a uniform distribution on the monoid. With this interpretation, the notion of resampling can be extended to designs having a certain group-invariance property. Two types of exchangeable array structures are considered in some detail, namely the oneway layout, and the two-way row-column exchangeable design. Although in both cases there is a unique group under which the sampling distribution of the observations is exchangeable, the choice of monoid is not unique. Different choices of monoid can lead to drastically different, and in some cases quite misleading, inferences.
Recent Advances in Experimental Downwind Sail Aerodynamics

Over the past two decades, the numerical and experimental progresses made in the field of downwind sail aerodynamics have contributed to a new understanding of their behaviour and improved designs. Contemporary advances include the numerical and experimental evidence of the leading-edge vortex, as well as greater correlation between model and full-scale testing. Nevertheless, much remains to be understood on the aerodynamics of downwind sails and their flow structures. In this paper, a detailed review of the different flow features of downwind sails, including the effect of separation bubbles and leading-edge vortices will be discussed. New experimental measurements of the flow field around a highly cambered thin circular arc geometry, representative of a bi-dimensional section of a spinnaker, will also be presented here for the first time. These results allow interpretation of some inconsistent data from past experiments and simulations, and to provide guidance for future model testing and sail design.
A Comparative Study of the Attitude of the Male and Female Elementary School Teachers towards Teaching Profession

The process of education is shaped and made by the teachers who play a pivotal role in web of educational system. Teaching characteristically is a moral enterprise and its function is aimed at guiding and working desirable growth in others. The need to know more about teacher and teaching stems not only from the commonness of the phenomenon, but also from the realization that our notion of teacher and teaching guides our future endeavors. There is a dearth of empirical evidence about the attitude of teachers towards their profession. Quantitative research methodology was deployed using descriptive design. The study included 160 pre and in-service elementary school teachers for which equal representative was given to pre and inservice teachers and both genders. The participants included 80 male and 80 female teachers. A three point validated and reliable attitude scale was used to gather the data which comprised 30 statements. The results of the present study revealed thatthe majority of teachers working in the elementary school and also the prospective one’s had less or not favorable attitude towards the teaching profession. The reasons for such attitude seemed to be justifiable, because of the working conditions and academic environment in schools as mentioned by the teachers were sufficient enough to be the great source of influence, development and reinforcement of a particular type of attitude. The study recommends the induction of teachers with the positive and more favorable attitude towards teaching profession.

Involvement of Slab‐Derived Fluid in the Generation of Cenozoic Basalts in Northeast China Inferred From Machine Learning

The origin and involvement of fluid in the generation of Cenozoic basalts in Northeast China are still under debate. Here we apply the machine learning methods of random forest and deep neural network to train models using data sets of global island arc and ocean island basalts. The trained models predict that most Cenozoic basalts in Northeast China are influenced by fluid and that the fluid activity decreases from east to west. The boundary defined by fluid activity coincides with the westernmost edge of the present‐day stagnant Pacific slab determined by seismic tomography and with the geochemical boundary defined by magnesium isotopes. These observations support the view that the fluid involved in the generation of the basalts is controlled by the stagnant Pacific slab instead of driven by the plume induced by the sinking Izanagi Plate.
Tumor suppressive effects of the pleiotropically acting miR-195 in colorectal cancer cells

Downregulation of miR-195 in colorectal cancer tissues has been reported in several studies. We investigated the impact exogenous induction of mature miR-195-5p on some malignant features of human colorectal cancer cells. Caco-2 and SW480 human colon cancer cell lines were transfected with a synthetic miR-195-5p mimic. Exogenous induction of miR-195-5p suppressed multiple mediators of invasion and angiogenesis in colorectal cancer cells and increased the apoptotic cell population in both cell lines. Also, migration of both cell lines was significantly compromised after miR-195 transfection. Our results are indicating a strong tumor suppressive role for miR-195 in human colorectal cancer.
Vitamin D and Male Fertility: An Updated Review

To date, the key role of vitamin D in male reproductive system has been suggested, since the expression of vitamin D receptors and metabolizing enzymes was demonstrated in the testis and spermatozoa. Nevertheless, a general consensus about the role of vitamin D in male fertility is still debated. The aim of this review is to provide an updated systematic revision of the current available literature, discussing the experimental and clinical evidence on the role of vitamin D in the regulation of testis hormone production, seminal parameters and male fertility. The consequences of vitamin D deficiency on serum levels of testicular hormones have been analysed by several observational and interventional studies, with controversial results. Equally, the experimental researches not were able to state a certain relationship between vitamin D status and testis hormone production. Possible bias, including age, body mass index, and baseline vitamin D status justified the differences among studies. As well as concerning the effect of vitamin D on semen parameters, most of the studies agreed in the possibility that vitamin D might have a positive effect on human male fertility potential, particularly through better sperm motility. Regarding pregnancy outcomes, normal level of vitamin D seems to be related to better pregnancies. However, all the previous studies displayed a wide heterogeneity in study design, population, methodology, and cut off values used for the evaluation of vitamin D status. Future studies are needed to better clarify the exact role of vitamin D on hormonal and seminal panel in both fertile and infertile men.

espanolResumen El objetivo de este estudio consistio en comprobar la capacidad de prediccion del apoyo a la autonomia del docente en educacion fisica, las necesidades psicologicas basicas y la motivacion autodeterminada sobre la diversion, la importancia e intencion hacia la educacion fisica y la actividad fisica habitual. Se empleo una muestra de 718 estudiantes (346 chicos y 372 chicas) con edades comprendidas entre los 13 y los 19 anos (M = 15,76, DT = 1,20). Se midio el apoyo a la autonomia, las necesidades psicologicas basicas, la motivacion, la diversion, la importancia de la educacion fisica, la intencionalidad para ser fisicamente activo y la actividad fisica habitual. Se realizaron analisis estadisticos descriptivos y las correlaciones bivariadas de todas las variables objeto de estudio, analisis factoriales confirmatorios de los instrumentos y un analisis mediante el modelo de regresion estructural. Los resultados revelaron relaciones positivas y significativas entre todas las variables. Asi, el apoyo a la autonomia predijo positivamente la satisfaccion de las necesidades psicologicas basicas, y esta, a su vez, predijo la motivacion autodeterminada, que predijo la diversion. La diversion predijo la importancia concedida a la educacion fisica, y esta la intencion de ser fisicamente activo, que finalmente predijo la tasa de actividad fisica habitual. Los resultados contribuyen a optimizar el compromiso de los jovenes hacia la actividad fisica, tanto dentro como fuera del aula. EnglishAbstract The objective of this study was to check the prediction capacity of teacher’s autonomy support in physical education, basic psychological needs and motivation self-determined about fun, importance and intention towards physical education and the usual physical activity. Participated a sample of 718 students (346 boys and 372 girls) with ages between 13 and 19 years (M = 15.76, SD = 1.20).

The results revealed a positive and significant relationship between all the variables. Thus, the autonomy support positively predicted the satisfaction of the basic psychological needs, and this, in turn, predicted self-determined motivation, which predicted fun the fun, that predicted the importance given to physical education, and it the intention to be physically active, which finally predicted the usual physical activity rate. The results help to optimize the commitment of young people to physical activity, both inside and outside the classroom.
The Effect of Volume Guarantee Ventilation on the Incidence of Retinopathy of Prematurity

Background: Newer technologies in neonatal ventilation such as combining volume guarantee with other modes of ventilation couldreducesomecomplicationsofartiﬁcialventilationbyreducingthedurationofventilationandoxygenneedsandﬂuctuations. Retinopathyof prematurity(ROP)isamultifactorialproblemmainlyaﬀectingpreterminfantswithdiﬀerentriskfactors. Although gestational age (GA) is the main risk factor for ROP, oxygen saturation and ﬂuctuations, arterial pressure of carbon dioxide, and some other parameters of ventilation such as ventilation duration have great impacts on ROP incidence and severity. Methods: One hundred and twelve infants with birthweight (BW) under 2000 g or GA under 36 weeks that needed artiﬁcial ventilation after admission to the neonatal intensive care unit were randomly assigned into two groups. In the ﬁrst group, neonates underwentsynchronizedintermittentmandatoryventilation(SIMV),pressuresupportventilation(PSV),orSIMV+PSVwithvolume guarantee (VG); and in the second group, neonates received ventilation without VG mode. All of the survived infants had ophthalmologic examination at the proper age by a retinal subspecialist to ﬁnd the diﬀerent stages of ROP. Results: Meandurationof ventilationwasreducedusingVGmodefrom74.08 ± 47.99to47. 91 ± 30.47hours(P< 0.05). Theoxygen requirementwaslessintheonesunderwentVGmodesandthepeakfractionalinspiredoxygen(FiO 2 )washigherininfantsreceiving SIMV+PSVwithoutVGcomparedtothatof infantsventilatedwithVGmode(52.8 ± 18.4vs. 40.3 ± 13.0,respectively). Thediﬀerence between highest and lowest FiO 2 was more in the group ventilated without VG ( ∆ FiO 2 = 9.52 in the group I and 18.30 in the group II,P< 0.05). Fluctuationof arterialpressureof carbondioxide(PaCO 2 )waslessprominentintheVGgroupascomparedtotheones ventilated without VG and the mean diﬀerence between maximum and minimum PaCO 2 was 7.16 in the group I and 13.36 in the group II (P < 0.05). Only three infants were diagnosed with ROP in the group I (with VG mode) in comparison with eight infants in the group II (odds ratio (OR) = 3.25, 95% conﬁdence interval (CI): 1.13 - 9.36). Severe ROP needing treatment was diagnosed in one infant in the group I vs. four infants in the group II (OR = 3, 95%CI: 0.63 - 14.23). Conclusions: ROP incidence in preterm infants could be reduced using VG mode of ventilation, since it is a safer ventilation mode in neonates due to reduction in the mean duration of ventilation, peak FiO 2 requirement, and PaCO 2 ﬂuctuation.
