Deep Two View Structure from Motion Revisited
Venue: CVPR
Year: 2021

Two view structure from motion (SfM) is the cornerstone of 3D reconstruction and visual SLAM. Existing deep learning based approaches formulate the problem by either recovering absolute pose scales from two consecutive frames or predicting a depth map from a single image, both of which are ill posed problems. In contrast, we propose to revisit the problem of deep two view SfM by leveraging the well posedness of the classic pipeline. Our method consists of 1) an optical flow estimation network that predicts dense correspondences between two frames; 2) a normalized pose estimation module that computes relative camera poses from the 2D optical flow correspondences, and 3) a scale invariant depth estimation network that leverages epipolar geometry to reduce the search space, refine the dense correspondences, and estimate relative depth maps. Extensive experiments show that our method outperforms all state of the art two view SfM methods by a clear margin on KITTI depth, KITTI VO, MVS, Scenes11, and SUN3D datasets in both relative pose and depth estimation.

Vulnerability, Freedom of Choice and Structural Global Injustices: The "Consent" to Exploitation of Migrant Women Workers
Year: 2019

This chapter analyzes the philosophical implications related to the "position of vulnerability" defined by the Directive 2011/36/EU on Preventing and Combating Trafficking in Human Beings and Protecting its Victims as "a situation in which the person concerned has no real or acceptable alternative but to submit to the abuse involved" (art. 2.2) In particular, the chapter focuses on the "choice" made by migrant women employed in care and domestic work and in the agricultural sector in Italy. The Italian labor market is marked by the exploitation of migrant women, especially women from Romania, due to social, economic and legal factors that will be considered from a gender perspective. Women's rights violations often have significant consequences for the effective protection of children's rights. The "choice" of these women with respect to their decision to emigrate and their "consent" to exploitative working and living conditions are explored by drawing on interviews collected in Sicily and Venice between 2014 and 2016. Different paradigms of "choice" and "adaptive preference" are analyzed to identify a theoretical model that can grasp these migrant women's experience. On the basis of the analysis, the last section focuses on the actors responsible for the violation of the rights of migrant women and their children within the Italian labor market.
A facile strategy for fine tuning the stability and drug release of stimuli responsive cross linked micellar nanoparticles towards precision drug delivery.
Venue: Nanoscale
Year: 2017

Precision drug delivery has a great impact on the application of precision oncology for better patient care. Here we report a facile strategy for fine tuning the stability, drug release and responsiveness of stimuli responsive cross linked nanoparticles towards precision drug delivery. A series of micellar nanoparticles with different levels of intramicellar disulfide crosslinkages could be conveniently produced with a mixed micelle approach. These micellar nanoparticles were all within a size range of 25 40 nm so that they could take full advantage of the enhanced permeability and retention (EPR) effect for tumor targeted drug delivery. The properties of these nanoparticles such as critical micelle concentration (CMC) stability, drug release and responsiveness to a reductive environment could be well correlated with the levels of crosslinking (LOC) Compared to the micellar nanoparticles with a LOC at 0% that caused the death of animals of two species (mouse and rat) due to the acute toxicity such as hemolysis, the nanoparticles at all other levels of crosslinking were much safer to be administered into animals. The in vitro antitumor efficacy of micellar nanoparticles crosslinked at lower levels (20% 50% were much more effective than that of 100% crosslinked micellar nanoparticles in SKOV 3 ovarian cancer cells.
Assessing variation in maize grain nitrogen concentration and its implications for estimating nitrogen balance in the US North Central region
Venue: Field Crops Research
Year: 2019

Accurate estimation of nitrogen (N) balance (a measure of potential N losses) in producer fields requires information on grain N concentration (GNC) to estimate grain N removal, which is rarely measured by producers. The objectives of this study were to (i) examine the degree to which variation in GNC can affect estimation of grain N removal, (ii) identify major factors influencing GNC, and (iii) develop a predictive model to estimate GNC, analyzing the uncertainty in predicted grain N removal at field and regional levels. We compiled GNC data from published literature and unpublished databases using explicit criteria to only include experiments that portray the environments and dominant management practices where maize is grown in the US North Central region, which accounts for one third of global maize production. We assessed GNC variation using regression tree analysis and evaluated the ability of the resulting model to estimate grain N removal relative to the current approach using a fixed GNC. Across all site year treatment cases, GNC averaged 1.15% ranging from 0.76 to 1.66% At any given grain yield, GNC varied substantially and resulted in large variation in estimated grain N removal and N balance. However, compared with GNC, yield differences explained much more variability in grain N removal. Our regression tree model accounted for 35% of the variation in GNC, and returned physiologically meaningful associations with mean air temperature and water balance in July (i.e. silking) and August (i.e. grain filling) and with N fertilizer rate. The predictive model has a slight advantage over the typical approach based on a fixed GNC for estimating grain N removal for individual site years (root mean square error: 17 versus 21 kg N ha 1, respectively) Estimates of grain N removal with both approaches were more reliable when aggregated at climate soil domain level relative to estimates for individual site years.
A shrinkage approach to joint estimation of multiple covariance matrices
Year: 2020

In this paper, we propose a shrinkage framework for jointly estimating multiple covariance matrices by shrinking the sample covariance matrices towards the pooled sample covariance matrix. This framework allows us to borrow information across different groups. We derive the optimal shrinkage parameters under the Stein and quadratic loss functions, and prove that our derived estimators are asymptotically optimal when the sample size or the number of groups tends to infinity. Simulation studies demonstrate that our proposed shrinkage method performs favorably compared to the existing methods.
Multi objective optimization of building energy performance using a particle swarm optimizer with less control parameters
Year: 2020

Good energy performance is very important for decreasing the consumption of energy intensive buildings. This paper studies a new multi objective evolutionary approach to optimize the building energy performance. Firstly, the problem is modeled as two objective optimization functions, i.e. minimizing the energy consumption and maximizing the comfort level. Next, a new solving algorithm based on bare bones particle swarm optimization is developed. In the algorithm, an improved update strategy with adaptive perturbation is proposed to overcome the disadvantage of easily local convergence of the traditional algorithm. The algorithm deletes control parameters including inertia weight and acceleration coefficients from the traditional algorithm, showing the advantage of easy to use. Applying the proposed algorithm into several buildings located in China, experiment result shows that the proposed algorithm can obtain good non dominated solutions, which is obviously better than that of those compared algorithms. The uncomfortable hours of the proposed algorithm on part cases reduce 11.82% but its energy consumption only increases 1.74% All indicate that the proposed algorithm is a powerful tool for optimizing building energy preference.

Research on the application of aviation kerosene in a direct injection rotary engine Part 2: Spray combustion characteristics and combustion process under optimized injection strategies
Year: 2020

Investigating the adaptability of aviation kerosene in the direct injection rotary engine is of great significance and practical value. In this paper, an optically visible constant volume combustion chamber platform with various optical diagnostic techniques was firstly set up to study the spray combustion characteristics of the fuel. Secondly, a reliable three dimensional dynamic simulation model of direct injection rotary engine was established to investigate the combustion process of aviation kerosene under optimized injection strategies. The experimental results show that the ambient temperature of 800 K and ambient pressure of 20 bar is the ignition limit of aviation kerosene under the condition of rotary engine. With the increase of ambient conditions, the ignition delay and the flame lift off length shorten continuously. At 850 K ambient temperature, when the ambient pressure reaches 25 bar, the lift off length will no longer shorten and remains at about 6 mm. The simulation results indicate that under the Injection position A Injection angle 90deg (Case A3) higher combustion efficiency before top dead center can be achieved due to more appropriate distribution, concentration and atomization quality of fuel at ignition timing. The peak pressure in cylinder reaches 38.89 bar, which means a better engine dynamic performance. Meanwhile, acceptable CO and Soot emissions are obtained by the complete combustion of fuel in Case A3, however, the higher combustion temperature makes the production of pollutant NO slightly higher than other injection strategies.

The highest number of individual bark beetles was found in Schima forest (4175 individuals; 37% and the lowest in Pine forest (1548 individuals; 14% The species number of bark beetles was highest in mixed forest (seven species; 41%
The Changing Landscape of Condominium Laws and Urban Governance in China
Year: 2016

China, as a transitional economy, meets its challenges by devising private law reforms while considering their potential conflict with prevailing cultural orientations and institutional settings. The academic discourse shows the multiple benefits that homeowner associations (HOAs) can offer. Yet, all of these proposed benefits are contingent on HOAs functioning well. What kind of law should help avoid dysfunctional practices and resolve effectively the disputes in the Chinese condominium context? In order to answer this, the initial step is to identify the problems pertaining to condominium governance in the Chinese context. To this end, this chapter aims to depict the institutional design and operational implementation of condominium governance in China. First, it traces the evolution of condominium ownership in China. It then provides a general overview of the current statutory framework relating to condominium ownership. Subsequently, some practical difficulties are illustrated in respect of demarcation between individual units and common property, pre sale of apartments, and allocation of participation quota. Furthermore, issues involving collective management of common property and the local government's role in shaping the property relations among stakeholders are addressed. A micro analysis of local condominium rules at the local level is highlighted to allay malpractice and developer overreaching. Finally, the chapter concludes on how to capture the dynamic property relations among key actors and between rules, norms, and cultural changes.
Projecting heat related mortality impacts under a changing climate in the New York City region.
Venue: American journal of public health
Year: 2007

We sought to project future impacts of climate change on summer heat related premature deaths in the New York City metropolitan region.  Current and future climates were simulated over the northeastern United States with a global to regional climate modeling system. Summer heat related premature deaths in the 1990s and 2050s were estimated by using a range of scenarios and approaches to modeling acclimatization (e.g. increased use of air conditioning, gradual physiological adaptation) RESULTS Projected regional increases in heat related premature mortality by the 2050s ranged from 47% to 95% with a mean 70% increase compared with the 1990s. Acclimatization effects reduced regional increases in summer heat related premature mortality by about 25% Local impacts varied considerably across the region, with urban counties showing greater numbers of deaths and smaller percentage increases than less urbanized counties.  Although considerable uncertainty exists in climate forecasts and future health vulnerability, the range of projections we developed suggests that by midcentury, acclimatization may not completely mitigate the effects of climate change in the New York City metropolitan region, which would result in an overall net increase in heat related premature mortality.
A Systematic Review of Integrated Functional Near Infrared Spectroscopy (fNIRS) and Transcranial Magnetic Stimulation (TMS) Studies
Venue: Front. Neurosci.
Year: 2019

The capacity for TMS to elicit neural activity and manipulate cortical excitability has created significant expectation regarding its use in both cognitive and clinical neuroscience. However, the absence of an ability to quantify stimulation effects, particularly outside of the motor cortex, has led clinicians and researchers to pair noninvasive brain stimulation with noninvasive neuroimaging techniques. fNIRS, as an optical and wearable neuroimaging technique, is an ideal candidate for integrated use with TMS. Together, TMS+fNIRS may offer a hybrid alternative to "blind" stimulation to assess NIBS in therapy and research.  In this systematic review, the current body of research into the transient and prolonged effects of TMS on fNIRS based cortical hemodynamic measures while at rest and during tasks are discussed. Additionally, studies investigating the relation of fNIRS to measures of cortical excitability as produced by TMS evoked Motor Evoked Potential (MEP) are evaluated. The aim of this review is to outline the integrated use of TMS+fNIRS and consolidate findings related to use of fNIRS to monitor changes attributed to TMS and the relationship of fNIRS to cortical excitability itself.  Key terms were searched in PubMed and Web of Science to identify studies investigating the use of both fNIRS and TMS. Works from Google Scholar and referenced works in identified papers were also assessed for relevance. All published experimental studies using both fNIRS and TMS techniques in the study methodology were included.  A combined literature search of neuroimaging and neurostimulation studies identified 53 papers detailing the joint use of fNIRS and TMS. 22/53 investigated the immediate effects of TMS at rest in the DLPFC and M1 as measured by fNIRS. 21/22 studies reported a significant effect in [HbO] for 40/54 stimulation conditions with 14 resulting an increase and 26 in a decrease. While 15/22 studies also reported [HbR] only 5/37 conditions were significant. Task effects of fNIRS+TMS were detailed in 16 studies, including 10 with clinical populations. Most studies only reported significant changes in [HbO] related measures. Studies comparing fNIRS to changes in MEP measured cortical excitability suggest that fNIRS measures may be spatially more diffuse but share similar traits.  This review summarizes the progress in the development of this emerging hybrid neuroimaging neurostimulation methodology and its applications. Despite encouraging progress and novel applications, a lack of replicated works, along with highly disparate methodological approaches, highlight the need for further controlled studies. Interpretation of current research directions, technical challenges of TMS+fNIRS, and recommendations regarding future works are discussed.
