The One-loop Open Superstring Massless Five-point Amplitude with the Non-Minimal Pure Spinor Formalism
No full textWe compute the massless five-point amplitude of open superstrings using the non-minimal pure spinor formalism and obtain a simple kinematic factor in pure spinor superspace, which can be viewed as the natural extension of the kinematic factor of the massless four-point amplitude. It encodes bosonic and fermionic external states in supersymmetric form and reduces to existing bosonic amplitudes when expanded in components, therefore proving their equivalence. We also show how to compute the kinematic structures involving fermionic states
Combined protein and calcium β-hydroxy-β-methylbutyrate induced gains in leg fat free mass: a double-blinded, placebo-controlled study
No full textBackground The leucine metabolite beta-hydroxy-beta-methylbutyrate (HMB) is widely used as an ergogenic supplement to increase resistance-training induced gains in fat free mass (FFM) and strength in healthy adults. Recent studies have questioned the effectiveness of HMB, particularly when a high protein diet is habitually consumed. To investigate the additive resistance-training induced effects of HMB and protein in untrained individuals, we conducted a randomized double-blind, placebo-controlled study that compared the effects of combined protein and HMB supplementation to protein supplementation alone on FFM and muscle strength after 12-week resistance training. Methods Sixteen healthy men (22 +/- 2 yrs) performed a periodized resistance-training program for twelve weeks (four sessions per week). The program comprised two mesocycles, characterized by a linear periodization and non-linear periodization, respectively, and separated by a 1-week tapering period. All participants received 60 g of whey protein on training days and 30 g of whey protein (WP) on non-training days. Participants were randomly assigned to additionally receive 3 g of calcium HMB (WP + HMB) or a placebo (WP + PLA). Body composition and physical fitness were tested before and after the 12-week training program. Whole-body and arm and leg fat free mass (FFM) were assessed by bioimpedance spectroscopy; upper arm and leg fat free cross sectional areas were also quantified using magnetic resonance imaging (MRI); upper and lower body strength were measured by One-repetition maximum (1-RM) bench press and leg press. Results Whole-body and segmental FFM increased in both groups (P < 0.001). However, gains in leg FFM were higher in WP + HMB vs. WP + PLA (arm FFM: + 6.1% vs. + 9.2%, P = 0.2; leg FFM: + 14.2% vs. + 7.0%, P < 0.01). No change in fat mass was observed (P = 0.59). 1-RM increased in both groups (P < 0.001). Conclusions Combined protein and HMB supplementation resulted in segmental, but not whole-body increases in FFM compared to protein supplementation alone. These findings could explain some of the controversial effects of HMB reported in previous studies and have practical implications for maximizing training-induced gains in FFM and clinical conditions associated with skeletal muscle deconditioning such as aging, sedentary lifestyles, bed rest and spaceflight
Pengembangan Media Pada Mata Pelajaran IPA Materi Tumbuhan Untuk Siswa
No full textThe purpose of this research is to produce products from the development of plant material media for elementary/MI students. This research uses research and development methods which use the development model procedure developed by Borg & Gall. In this research, the author limits it to the product development process. The dissemination process and large-scale testing will be written separately in another article. From this development, a product was produced in the form of media that uses the Articulate Storyline 3 application which can combine graphics and animation so it is very suitable for elementary school students. The use of computer-based technology is a way to produce or convey material using technology-based sources, where the information or material presented is stored in digital form. The author is here to provide a solution through the development of media related to plant material that can overcome problems for elementary school students
Media Ekopedagik Dalam Pembelajaran (TPS) Think Pair Share Untuk Menunjang Hasil Belajar Peserta Didik
No full textIn this paper, the author tries to relate the literature study related to the comparison of Eco pedagogic media with TPS (Think Pair Share) learning in supporting student learning outcomes. From several studies such as relevant studies coupled with supporting theories, it is stated that Eco pedagogic media and TPS (Think Pair Share) models will provide broad opportunities for students to be able to think and train their reasoning so that students can then work together in groups. and can explain and provide information to other students. Of course, the information obtained is sourced from Eco pedagogic media in the form of the surrounding environment. The hope is that this Eco pedagogic media in TPS (Think Pair Share) learning can be used as a reference for every educator in creating an optimal learning atmosphere
Money and housing: evidence for the euro area and the US
No full textThis paper examines the relation between money and housing variables in the euro area and in the US. Our empirical model is based on a standard money demand relation which is augmented by housing market variables. In doing so, co-integrated money demand relationships can be established for both the euro area and the US. Furthermore, we find evidence for asset inflation channels, that is, liquidity fuels housing market developments. --money demand,asset inflation,housing,wealth
How do banks adjust their capital ratios? Evidence from Germany
No full textWe analyze the dynamics of banks' regulatory capital ratios. Using monthly data of regulatory capital ratios for a subset of large German banks, we estimate the target level and the adjustment speed of the capital ratio for each bank separately. We find evidence that, first, there exists a target level for a substantial percentage of banks; second, that private banks and banks with liquid assets are more likely to adjust their capital ratio tightly; and third, that banks compensate for low target capital ratios with low asset volatilities and high adjustment speeds. Fourth, banks with a target capital ratio seem to use an internal lower limit for their current ratios that is just above the regulatory minimum of 8%. --Regulatory bank capital,target capital ratio,partial adjustment,Ornstein-Uhlenbeck process
Stress testing of real credit portfolios
No full textStress testing has become a crucial point on the Basel II agenda, mainly as Pillar I estimates do not explicitly take portfolio concentration into account. We start from the credit portfolio of the German pension insurer being a cross-sectional representation of the German economy and subsequently compose three bank portfolios corresponding to a small, medium and large bank. We apply univariate and multivariate stress tests both by using the Internal Rating based (IRB) model and by a model that additionally allows for variation of correlation. In a severe multivariate stress scenario based on historical data for Germany IRB capital requirements increase by more than 80% with little differences between the credit portfolios. If stress testing is additionally applied to correlation, the Value-at-Risk increases by up to 300% and portfolio differences materialize. --Credit Portfolio,Exposure concentration,Stress Testing,Basel II,Economic Capital
Coin migration within the euro area
No full textThis paper analyses how many euro coins outflow from Germany and which composition of coins is to be expected in the long run. To this end, a simple mathematical model is formulated and calibrated for €1 coins. The introduction of the euro coins in 2002 presented a unique opportunity to analyse the cross-border migration and the mixing process of coins in different euro-area countries. Based on research by Stoyan and depending on growth assumptions, the annual outflow of German €1 coins is calculated to lie somewhere between 4% and 5%. In the long run, the ratio of German €1 coins in Germany is likely to converge to around 50%. --Euro coins,coin volumes,mixing process
Real-time forecasting and political stock market anomalies: evidence for the U.S.
No full textUsing monthly data for the period 1953-2003, we apply a real-time modeling approach to investigate the implications of U.S. political stock market anomalies for forecasting excess stock returns. Our empirical findings show that political variables, selected on the basis of widely used model selection criteria, are often included in real-time forecasting models. However, they do not contribute to systematically improving the performance of simple trading rules. For this reason, political stock market anomalies are not necessarily an indication of market inefficiency. --Political stock market anomalies,predictability of stock returns,efficient markets hypothesis,real-time forecasting
