Geometry-aware multi-task learning for binaural audio generation from video

Human audio perception is inherently spatial and videos with binaural audio simulate the spatial experience by delivering different sounds to both ears. However, videos are typically recorded with mono audio and hence generally do not offer the rich audio experience of binaural audio. We propose an audio spatialization method that uses the visual information in videos to convert mono audio to binaural. We leverage the spatial and geometric information about the audio present in the visuals of the video to guide the learning process. We learn these geometry aware features in visuals in a multi-task manner to generate rich binaural audio. We also generate a large video dataset with binaural audio in photorealistic environments to better understand and evaluate the task. We demonstrate the efficacy of our method to generate better binaural audio by learning more spatially coherent visual features by extensive evaluation on two datasets.Computer Science

Role of Prosthodontics in Forensic Odontology

Forensic odontology plays an important and often decisive role in the identification of disaster victims. Dental description of unknown or missing persons in cases of mass disasters is a very successful means of identification in forensic research. Difficulties arise if the natural dentition has been lost for one reason or another and has been replaced by dental prosthesis. From the prosthodontist view this difficulty can be prevented by delivering a prosthesis that carries patient identification.    Forensic identification based on assessment of prosthodontics appliances is assuming greater significance, as labeling of dentures and other prosthetic appliances could provide vital clues for patient identification.&nbsp

Prosthetic management following mandibular resection: A clinical report

Mandibular resection leads to altered mandibular movements, disfigurement, difficult in swallowing, impairedspeech and articulation, and deviation of the mandible towards the resected site.Numerous prosthetic methods employed to reduce or minimize deviation and improve function include maxillomandibular fixation, implant supported prosthesis, removable mandibular guide flange prosthesis, andpalatal based guidance restoration.Management of patients who require mandibular resection without bony reconstruction is difficult. This articledescribes the prosthetic management of a patient following segmental mandibular resection

CFL: Causally Fair Language Models Through Token-level Attribute Controlled Generation

We propose a method to control the attributes of Language Models (LMs) for the text generation task using Causal Average Treatment Effect (ATE) scores and counterfactual augmentation. We explore this method, in the context of LM detoxification, and propose the Causally Fair Language (CFL) architecture for detoxifying pre-trained LMs in a plug-and-play manner. Our architecture is based on a Structural Causal Model (SCM) that is mathematically transparent and computationally efficient as compared with many existing detoxification techniques. We also propose several new metrics that aim to better understand the behaviour of LMs in the context of toxic text generation. Further, we achieve state of the art performance for toxic degeneration, which are computed using \RTP (RTP) benchmark. Our experiments show that CFL achieves such a detoxification without much impact on the model perplexity. We also show that CFL mitigates the unintended bias problem through experiments on the BOLD dataset.Comment: 19 pages, 10 figures. Findings of ACL 202

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe
