The influence of eight different N-terminal protecting groups (For, Ac, Boc, Fmoc, Mal, Pheac, Aloc and Z) on the α-chymotrypsin-catalyzed synthesis of the dipeptide derivative X-Phe-Leu-NH2 in organic media was studied. Groups such as Ac, For, Boc, Z, Mal, Pheac and Alloc always rendered good peptide yields (92% to 99%) either in acetonitrile or in ethyl acetate. Good correlations were found betw

This paper presents tractable two parameter stochastic processes of the drift-diffusion class in order to model economic processes with a focus on income. Starting from the resulting closed-form, cross-sectional distributions, easy-to-interpret expressions for mobility and inequality (including the popular Gini-coefficient) are derived. The general processes are applied to discuss income mobility

Recent research has brought to the fore vital discussions about the logics andassumptions used to evaluate the significance and effectiveness of leadershipdevelopment programs and practices (Vongswasdi et al., 2023). In this chapter,we extend these discussions by reviewing research that considers the logics andassumptions—especially the assumptions about gender and leadership—thatfunction to frame

We study simulated annealing algorithms to maximise a function psi on a subset of R-d. In classical simulated annealing, given a current state theta(n) in stage n of the algorithm, the probability to accept a proposed state z at which psi is smaller, is exp(-beta(n+1)(psi(z) - psi (theta(n))) where (beta(n)) is the inverse temperature. With the standard logarithmic increase of (beta(n)) the probab

The ratio of production cross sections of the W and Z bosons with exactly one associated jet is presented as a function of jet transverse momentum threshold. The measurement has been designed to maximise cancellation of experimental and theoretical uncertainties, and is reported both within a particle-level kinematic range corresponding to the detector acceptance and as a total cross-section ratio

We extend our earlier work on the massive O(N) non-linear sigma model to other observables. We derive expressions at leading order in the large N expansion at all orders in the loop expansion for the decay constant, vacuum expectation value, meson meson scattering and the scalar and vector form factors. This is done using cactus diagram resummation using a generalized gap equation and other recurs

Basel II requires Value at Risk (VaR) as a standardized risk measure for calculating market risk. However, the validity of the risk measure has been questioned since it neglects the losses beyond the VaR level. Expected Shortfall (ES) is a response to this limitation, as it is defined as the average of the losses ignored by VaR. This study applies VaR and ES to three commodities; gold, oil and cor

We have studied PCB concentration and domain (one to three congeners) distribution in water and fish along a gradient of a contaminated river system. The river was contaminated by a small lake that contains about 400 kg of PCB in the sediment. The PCB concentration in water in the outlet from the lake was 8.6 ng/L, which was 12 times higher than upstream. PCB concentration in fish from the lake wa

Our study finds strong liquidity commonality across China's metal futures contracts, as about 47% of liquidity changes in individual contracts can be explained by a market-wide factor during 2019-2025. Liquidity fluctuations also show mean-reverting behavior, meaning they tend to return to normal levels after short-term shocks. Moreover, this co-movement in liquidity remains statistically sign

Att läsa Mario Vargas Llosas Staden och hundarna är en utmaning för svenska universitetsstudenter som läser spanska som främmande språk, men trots detta visar kursutvärderingar att de tenderar att uppskatta upplevelsen. Denna studie fokuserar på att utforska studenternas läsprocess och deras reaktioner på texten genom ett läsloggprojekt. Felskis (2008) kategorier igenkänning, kunskap, förtrollning

Introduction. Building block chemicals, such as butanol, can be produced via fermentation and biobased feedstocks as a more sustainable alternative compared to the current petrochemical methods. However, the butanol fermentation is subjected to low product titres (<20 g/L) due to product inhibition of the bacteria [1]. To overcome this continuous fermentation can be applied, as it offers considera

This study investigated how three verbalization protocols, Silent, Type 1 (think-aloud), and Type 3 (explanatory verbalization), influence problem-solving performance on insight and non-insight problems within both spatial and verbal domains. Twenty-eight participants completed twelve problems (three per category) under each condition. Informed by theories of insight, verbal overshadowing, and cog

Gaze-control and gaze-assistance in software development tools have so far been explored in the setting of code editing, but other developer activities like code review could also benefit from this kind of tool support.In this paper, we present GANDER, a platform for user studies on gaze-assisted code review. As a proof of concept, we extend the platform with an assistant that highlights name rela
