Deconvolving the information from an imperfect spherical gravitational wave antenna
We have studied the effects of imperfections in spherical gravitational wave
antenna on our ability to properly interpret the data it will produce. The
results of a numerical simulation are reported that quantitatively describe the
systematic errors resulting from imperfections in various components of the
antenna. In addition, the results of measurements on a room-temperature
prototype are presented that verify it is possible to accurately deconvolve the
data in practice.Comment: 5 pages, 2 figures, to be published in Europhysics Letter

Neuroendokrynna regulacja masy ciała: integracja tkanki tłuszczowej, układu pokarmowego i mózgu
Human body weight is maintained at a fairly stable level regardless of changes in energy intake and energy expenditure. Compensatory
mechanisms within the central nervous system (CNS), which regulate food intake and energy expenditure, are triggered by other central
and peripheral signals. Peripherally, the main sources of those signals are the adipose tissue, gastrointestinal tract, and pancreas. The main
signal originating from the adipose tissue is leptin, which promotes the activation of anorexigenic pathways in the CNS. Similarly, the
central action of insulin also reduces food intake and stimulates catabolic pathways. The gastrointestinal tract contributes with several
peptides that influence food intake, such as ghrelin, glucagon-like peptide 1 (GLP-1), peptide YY (PYY), oxyntomodulin (OXM), and
cholecystokinin (CCK). Other substances secreted by the pancreas, such as pancreatic polypeptide (PP) and amylin, a hormone co-secreted
with insulin, also affect energy balance. More recently, the endocannabinoid system has also been identified as a contributor in the
maintenance of energy balance. Better understanding of these mechanistic systems involved in the regulation of energy metabolism will
hopefully lead to the development of new therapeutic approaches against obesity, metabolic syndrome, and other nutritional disorders.

zużywania. Mechanizm kompensacyjny w ośrodkowym układzie nerwowym (CNS, central nervous system [OUN]), który reguluje przyjmowanie
pokarmu i wydatek energii jest uruchamiany przez inne sygnały ośrodkowe i obwodowe. Obwodowo, źródłem tych sygnałów
jest tkanka tłuszczowa, układ pokarmowy i trzustka. Głównym sygnałem pochodzącym z tkanki tuszczowej jest leptyna, która powoduje
aktywację anoreksogennych dróg przekazu sygnału w CNS. Podobnie, oddziaływanie ośrodkowe insuliny także zmniejsza przyjmowanie
pokarmu i stymuluje kataboliczne drogi przekazu sygnału.
W układzie pokarmowym współdziała kilka peptydów, które wpływają na przyjmowanie pokarmu, takie jak grelina, peptyd podobny do
glukagonu (GLP-1, glucagon-like peptide), peptyd YY (PYY, peptide YY), oksyntomodulina (OXM, oxyntomodulin) i cholecystokinina (CCK,
cholecystokinin), Pozostałe substancje wydzielane przez trzustkę, takie jak polipeptyd trzustkowy (PP, pancreatic polypeptide)
i amylina, hormon wydzielany jednocześnie z insuliną , także wpływają na równowagę energetyczną. W najnowszych badaniach stwierdzono,
że układ endokannabinoidowy przyczynia sie do zachowania równowagi energetycznej. Lepsze zrozumienie mechanizmów
układów wpływających na regulacje przemiany energii przyczyni się do rozwoju nowych terapii otyłości, zespołu metabolicznego
i innych zaburzeń odżywiania. (Endokrynol Pol 2010; 61 (2): 194-206
The use of lexical complexity for assessing difficulty in instructional videos
Although measures of lexical complexity are well established for printed texts, there is currently no
equivalent work for videos. This study, therefore, aims to investigate whether existing lexical complexity
measures can be extended to predict second language (L2) learners’ judgment of video difficulty. Using a
corpus of 320 instructional videos, regression models were developed for explaining and predicting
difficulty using indices of lexical sophistication, density, and diversity. Results of the study confirm key
dimensions of lexical complexity in estimates of video difficulty. In particular, lexical frequency indices
accounted for the largest variance in the assessment of video difficulty (R2 = .45). We conclude with
implications for CALL and suggest areas of further research
