Because of their wide use in molecular modeling, methods to compute molecular surfaces have received a lot of interest in recent years. However, most of the proposed algorithms compute the analytical representation of only the solvent-accessible surface. There are a few programs that compute the analytical representation of the solvent-excluded surface, but they often have problems handling sin...

Simulation results suggest that a maximum size matching (MSM) algorithm will lead to 100% throughput for uniform Bernoulli i.i.d traffic. Previous analysis on the throughput of MSM algorithms enforce deterministic constraints on the joint arrival traffic. In this paper we explore MSM algorithms under Bernoulli arrivals. We show that when the arrival traffic is admissible and cells are scheduled...

This paper builds on a collaborative pilot project Critical Multilingual Language Awareness (CMLA) in linguistically diverse Preparatory Class with migrant adolescents Sweden. Importantly, the approach involved Study Mentors (MSMs), whose role normally is to provide scaffolding strongest language of recently arrived students facilitate learning instruction. Previous research has shown that MSMs...

The pollution of water bodies by pharmaceuticals and personal care products (PPCPs) has attracted widespread concern due to their use pseudo-persistence, but effects on sediments are less known. In this study, solid-phase extraction-high performance liquid chromatography–tandem mass spectrometry (SPE-LC/MSMS) was used investigate the occurrence ecological risks five typical in thirteen key rese...

The scallop, Patinopecten yessoensis, was screened for new saxitoxin analogues to study the metabolism of paralytic shellfish toxins (PSTs), and this resulted in discovery two analogues: M5-hemiaminal (HA) M6-HA. M5-HA isolated its structure determined by using NMR spectroscopy. It contains hydrogen at C-4 with opposite stereochemistry that saxitoxin, a hemiaminal formed between 9-NH2 hydrated ...

We thank Robins et al. (1) for their thoughtful commentary on our article (2). Before responding, we wish to point out that they altered our notation slightly, using m rather than j to refer to the baseline time point. Robins et al. distinguish between two types of historyadjusted marginal structural models (HA-MSMs), those that consider an outcome at a fixed time point (‘‘group 1,’’ or those w...

BACKGROUND Dating apps play a major role in connecting men who are interested in meeting other men for sex. Besides finding a partner, these tools are also exploited for other activities such as encouraging people to get involved in the habit of illicit drug consumption (substance use). METHODS This study evaluated the overall usage of dating apps among Thai men who have sex with men (MSMs), ...
