We report a two-color magneto-optical trap (MOT) for ytterbium atoms operating at a low magnetic field gradient down to 2 G/cm where a conventional MOT using the singlet transition (6s 1S0 → 6s6p 1P1) is unable to trap atoms. By simultaneously applying laser light on both the broad-linewidth singlet transition and the narrow-linewidth triplet transition (6s 1S0 → 6s6p 3P1), we load and trap 4.0...

The root-to-root travel of the beneficial bacterium Azospirillum brasilense on wheat and soybean roots in agar, sand, and light-textured soil was monitored. We used a motile wild-type (Mot) strain and a motility-deficient (Mot) strain which was derived from the wild-type strain. The colonization levels of inoculated roots were similar for the two strains. Mot cells moved from inoculated roots (...

Objective. Walking while simultaneously engaged in another activity becomes more difficult as one grows older. Here, we address the issue of changes in dual-task behavior at different stages of life, particularly in the latter stages. Methods. We developed a dual task that combined walking along an 8-m walkway with a multiple object tracking (MOT) task of increasing difficulty. This secondary c...

Detection and learning based appearance feature play the central role in data association based multiple object tracking (MOT), but most recent MOT works usually ignore them and only focus on the hand-crafted feature and association algorithms. In this paper, we explore the high-performance detection and deep learning based appearance feature, and show that they lead to significantly better MOT...

dered if guidance cue-induced changes in NFPC protein synthesis may play a role here. Interestingly, stimulating cultured growth cones with Sema3A, a repellent molecule expressed in telencephalic regions adjacent to the MOT, elevates NFPC protein twofold within 10 min. Therefore, we now postulate a growth cone turning mechanism involving Sema3A-induced increases in TAF1mediated NFPC activity at...

Maternal obesity is associated with obesity and metabolic disorders in offspring. However, intervention strategies to reverse or ameliorate the effects of maternal obesity on offspring health are limited. Following maternal undernutrition, taurine supplementation can improve outcomes in offspring, possibly via effects on glucose homeostasis and insulin secretion. The effects of taurine in media...

OBJECTIVE Real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback (NF) uses feedback of the patient's own brain activity to self-regulate brain networks which in turn could lead to a change in behavior and clinical symptoms. The objective was to determine the effect of NF and motor training (MOT) alone on motor and non-motor functions in Parkinson's Disease (PD) in a 10-week sma...

Notre société fonctionne sur un principe de base envahissant. Un mot est censé représenter cet étrange principe. Ce mot, parfaitement anodin, s’applique à quantité d’organisations, d’opérations, dont certaines sont proches de l’individu et d’autres, tellement éloignées qu’on a peine à les imaginer si l’on n’est pas spécialiste, partie prenante ou abusivement informé. L’économie. Ce mot recouvre...

We propose a method for laser cooling and trapping a substantial class of polar molecules, and in particular titanium (II) oxide (TiO). This method uses pulsed electric fields to nonadiabatically remix the ground-state magnetic sublevels of the molecule, allowing us to build a magneto-optical trap (MOT) based on a quasi-cycling J′ = J′′−1 transition. Monte-Carlo simulations of this electrostati...
