QMCube (QM3 ) is a suite written in the Python programming language, initially focused on multiscale QM/MM simulations of biological systems, but open enough to address other kinds of problems. It allows the user to combine highly efficient QM and MM programs, providing unified access to a wide range of computational methods. The suite also supplies additional modules with extra functionalities. These modules facilitate common tasks such as performing the setup of the models or process the data generated during the simulations. The design of QM3 has been carried out considering the least number of external dependencies (only an algebra library, already included in the distribution), which makes it extremely portable. Also, the modular structure of the suite should help to expand and develop new computational methods.

This research evaluated the South Carolina Alcohol Enforcement Team impact for reducing retail alcohol access to underage persons to decrease drinking and driving crashes among that population.

The natural research experiment used interrupted time-series (ITS) analyses of drinking and driving crashes involving under 21-year-old drivers from July 2006 through December 2016 (126-month period=4,782 Driving Under Influence [DUI] crashes for under 21-year-old drivers, µ=38 crashes per month). Additional data analyzed included the monthly total number of retail compliance checks (total during 126-month period=64,954 compliance checks completed, µ=515.5 checks per month), the average percentage of underage alcohol purchases (total completed during 126-month period=8,814 purchases, µ=70 purchases per month), and a calculated measure of the percent of the population under 21years old exposed to compliance checks each month. We used drinking and driving crashes for 21-year-old and over drivers as a control time sernt (T=-8.18, p<0.001).

This longitudinal study provides strong evidence of sustained reductions in alcohol availability to underage youth can subsequently reduce alcohol-related traffic crashes. Reductions found in this study continued over several years, considerably longer than any previous equivalent research has shown.

Sleep disturbances in women occur frequently throughout pregnancy. Previous studies have demonstrated that the increasing incidence of physiological and psychological illness is concurrent with increasing sleep deprivation and poor sleep quality in adults and children.

The Shanghai Sleep Birth Cohort Study (SSBCS) was established to examine the effect of sleep disturbances during the third trimester on emotional regulation of mothers; to assess the effect of maternal sleep during pregnancy on the growth and development of children; and to explore the influence of children's sleep characteristics on physical and social-emotional development.

The study was conducted in the Renji Hospital in Pudong New District, Shanghai from May 2012 to July 2013. Women and their newborns who met the inclusion criteria and agreed to participate in this study were recruited to the SSBCS.

The follow-up visits for children were conducted at the age of 42days, 3, 6, 9, 12, 18, and 24months, and 3, 4, and 6years. Data on demexaminations, neurodevelopmental and psychiatric assessment, diet records, and biological samples make this research platform an important resource for examining the potential effects of sleep characteristics on both maternal and child health.For diurnal nonhuman primates, shifting among different sleeping sites may provide multiple benefits such as better protection from predators, reduced risk of parasitic infection, and closer proximity to spatially and temporally heterogeneous food and water. This last benefit may be particularly important in sleeping site selection by primates living in savanna-woodlands where rainfall is more limited and more seasonally pronounced than in rainforests. Here, we examined the influence of rainfall, a factor that affects food and water availability, on the use of sleeping sites by anubis baboons (Papio anubis) over two 13-month study periods that differed in rainfall patterns. We predicted that during wet periods, when food and water availability should be higher, the study group would limit the number of sleeping sites and would stay at each one for more consecutive nights than during dry periods. Conversely, we predicted that during dry periods the group would increase the number of sleeping sites and stay at each one for fewer consecutive nights as they searched more widely for food and water. We also predicted that the group would more often choose sleeping sites closer to the center of the area used during daytime (between 0700 and 1900) during wet months than during dry months. Using Global Positioning System data from collared individuals, we found that our first prediction was not supported on either monthly or yearly timescales, although past monthly rainfall predicted the use of the main sleeping site in the second study period. DRB18 in vitro Our second prediction was supported only on a yearly timescale. This study suggests that baboons' choice of sleeping sites is fluid over time while being sensitive to local environmental conditions, one of which may be rainfall.Studies on primate tool-use often involve the use of baseline conditions, as they allow for the examination of any differences in the subjects' behavior before and after the introduction of a tool-use task. While these baseline conditions can be powerful for identifying the relative contributions of individual and social learning for the acquisition of tool-use behaviors in naïve (usually captive) subjects, many have criticized them for being too short, and not allowing enough time for the behavior to develop spontaneously. Furthermore, some wild tool-use behaviors such as chimpanzee nut-cracking require animals to manipulate and familiarize themselves with the materials of the behavior within a "sensitive learning period" before it develops later on in life. One solution to this problem is to implement long-term baselines, in which, with collaboration with zoological institutions, the materials of the behavior are left in the enclosure for an extended period. The keepers would then be asked not to demonstrate or train the animals in the target behavior, but to report back to the researchers if they observe the behavior emerge during this extended period.
