A new formulation of non-relativistic diffeomorphism invariance

We provide a new formulation of nonrelativistic diffeomorphism invariance. It is generated by localising the usual global Galilean Symmetry. The correspondence with the type of diffeomorphism invariant models currently in vogue in the theory of fractional quantum Hall effect has been discussed. Our construction is shown to open up a general approach of model building in theoretical condensed matter physics. Also, this formulation has the capacity of obtaining Newton - Cartan geometry from the gauge procedure.Comment: minor changes, new reference added, to appear in PL

tagE: Enabling an Embodied Agent to Understand Human Instructions

Natural language serves as the primary mode of communication when an intelligent agent with a physical presence engages with human beings. While a plethora of research focuses on natural language understanding (NLU), encompassing endeavors such as sentiment analysis, intent prediction, question answering, and summarization, the scope of NLU directed at situations necessitating tangible actions by an embodied agent remains limited. The inherent ambiguity and incompleteness inherent in natural language present challenges for intelligent agents striving to decipher human intention. To tackle this predicament head-on, we introduce a novel system known as task and argument grounding for Embodied agents (tagE). At its core, our system employs an inventive neural network model designed to extract a series of tasks from complex task instructions expressed in natural language. Our proposed model adopts an encoder-decoder framework enriched with nested decoding to effectively extract tasks and their corresponding arguments from these intricate instructions. These extracted tasks are then mapped (or grounded) to the robot's established collection of skills, while the arguments find grounding in objects present within the environment. To facilitate the training and evaluation of our system, we have curated a dataset featuring complex instructions. The results of our experiments underscore the prowess of our approach, as it outperforms robust baseline models.Comment: Accepted in EMNLP Findings 202

Immediate induction of labor in premature rupture of membranes at term (PROMT)-vaginal Misoprostol tablet versus PGE2 gel: a randomized comparative study

Background: The aim of the study is to compare immediate induction with vaginal misoprostol tablet and immediate induction with vaginal PGE2 gel in women with premature rupture of membranes at term (PROMT).Methods: Nine hundred thirty-two women with PROM at term were assigned randomly to receive intravaginal 25μg misoprostol tablet, 4 hourly with a maximum of 5 doses or 0.5 mg vaginal PGE2 gel 6 hourly with a maximum of 2 doses. The primary outcome measures were cesarean section rate, admission to delivery interval and induction to delivery interval. Secondary outcomes included, mode of delivery, and maternal and neonatal safety outcome. Results were calculated applying Fisher Exact Test, Chi square test, t test and calculating the P-value using an alpha level of 0.05 for Type I error.Results: The mean time from admission to delivery was 13.16 hours in the misoprostol group and 13.56 hours in the PGE2 group (P= 0.3014). Induction to delivery interval was also comparable between the groups (10.23 h versus 10.18 h).Caesarean section rate did not differ significantly between groups (12.13% versus 15.74% ,P=0.135 RR 0.783 95% CI 0.568-1.079).More women in misoprostol group had instrumental delivery (7.57% versus 4.25%, P=0.031, RR 1.089 95% CI 1.04-3.03).The  neonatal outcomes were comparable between the groups . Maternal outcomes were not significantly different except incidence of analgesic use (P=0.009 RR 1.62 95% CI 1.03-1.30), meconium stained liquor (P=.0096 RR 2.03 CI 1.17-3.53) and   number of digital vaginal examinations (P<.0001) in misoprostol group.Conclusions: Vaginal misoprostol is equally efficacious in labor induction and demonstrates a similar fetal and maternal safety profile to PGE2 gel
