We investigate how the way galaxies acquire their gas across cosmic time in cosmological hydrodynamic simulations is modified by a comprehensive physical model for baryonic feedback processes. To do so, we compare two simulations – with and without feedback – both evolved with the moving mesh code AREPO. The feedback runs implement the full physics model of the Illustris simulation project, inc...

ABSTRACT A novel concept of the Cold-Electron Bolometer (CEB) with strong electrothermal feedback has been proposed. The concept is based on direct electron cooling of the absorber that serves as negative electrothermal feedback for incoming signal. This feedback is analogous to TES (transition-edge sensor) but additional dc heating is replaced by deep electron cooling to minimum temperature. I...

this study aimed at investigating the effect of learners’ gender on their preferences for corrective feedback. learners’ prefer- ences which were investigated included the necessity, frequency, timing, type, method, and delivering agent of error treatment. to this end, a questionnaire was administered to a random sample of 100 participants (50 males and 50 females) studying english (efl) at shi...

introduction: feedback is very important in education and can help quality in the training process and orient the trainees in clinical contexts. this study aimed to assess the residents’ points of view about feedback in clinical education at shiraz university of medical sciences. methods: the sample of this study included 170 medical residents attending medical workshops in shiraz university of...

Previous work has shown that a convective cloud feedback can greatly increase high-latitude surface temperature upon the removal of sea ice and can keep sea ice from forming throughout polar night. This feedback activates at increased greenhouse gas concentrations. It may help to explain the warm ‘‘equable climates’’ of the late Cretaceous and early Paleogene eras (;100 to ;35 million years ago...

The feedback between climate and carbon cycle systems is critical to the prediction of future CO2 concentration in the atmosphere and the capacity of the oceans to take up CO2 from the atmosphere. We calculated the magnitudes of the potential feedback between the increase of atmospheric CO2 concentration, the carbonate chemistry of the oceans (via a buffer factor), and the global temperature. W...

recent interaction studies havefocused on the relationship between interactional feedback and l2 development.despite the large body of knowledge in this regard, few studies have examinedlearners’ preferences for interactional feedback. besides, different findingshave been reported concerning learners’ preferences for feedback and none hasexamined the factors accounting for the variation in the ...

since the emergence of the process-oriented approach in second language writing instruction, the issues of writing instruction have been predominantly concerned with what and how error feedback should be given to the students’ writing. the present study investigated the effect of explicit corrective feedback on writing accuracy of iranian intermediate efl learners (n = 44) in hamedan islamic az...

The goal of this paper is to provide an initial assessment water-vapor feedback (WVF) in humid urban heat island (UHI) environments based on temperature difference data. To achieve this, a novel WVF model was developed that can analyze global and UHI local Specifically, the applied comparative literature study similar cities located versus dry climates. found daytime ?T observed be 3.3 K higher...

To develop indigenous alternative and renewable energy resources, long-term subsidy programs (1986–1991 and 2000–present) for solar water heaters have been enforced in Taiwan. By the end of 2010, the total installed area of solar collectors had exceeded 2 million square meters. However, over 98% of solar water heaters were used in residential systems for hot water production, with the areas of ...
