Isolation, identification, and environmental adaptability of heavy metal resistant bacteria from ramie rhizosphere soil around mine refinery
Venue: 3 Biotech
Year: 2017

Six bacteria strains from heavy metal polluted ramie rhizosphere soil were isolated through Cd2+ stress, which were numbered as JJ1, JJ2, JJ10, JJ11, JJ15, and JJ18. Sequence alignment and phylogenic analysis showed that strain JJ1 belonged to Pseudomonas, strain JJ2 belonged to Cupriavidus, strains JJ11 and JJ15 belonged to Bacillus, and strains JJ10 and JJ18 belonged to Acinetobacter. The tolerance capability of all the strains was the trend of Pb2+ Zn2+ Cu2+ Cd2+ the maximum tolerance concentration to Cd2+ was 200 mg/L, to Pb2+ was 1600 mg/L, to Zn2+ was 600 mg/L, and to Cu2+ was 265 mg/L. Strains JJ1, JJ11, JJ15, and JJ18 could grow well under pH 9.0, and strains JJ2, JJ11, and JJ18 could grow well under 7% of NaCl. The results showed that as a whole these strains had high environmental adaptability. This is the first report that heavy metal tolerant bacteria were found from ramie rhizosphere soil, which could be as a foundation to discover the relationship between ramie, rhizosphere bacteria and heavy metals.
Uncanny valley as a window into predictive processing in the social brain
Venue: Neuropsychologia
Year: 2018

Uncanny valley refers to humans' negative reaction to almost but not quite human agents. Theoretical work proposes prediction violation as an explanation for uncanny valley but no empirical work has directly tested it. Here, we provide evidence that supports this theory using event related brain potential recordings from the human scalp. Human subjects were presented images and videos of three agents as EEG was recorded: a real human, a mechanical robot, and a realistic robot in between. The real human and the mechanical robot had congruent appearance and motion whereas the realistic robot had incongruent appearance and motion. We hypothesize that the appearance of the agent would provide a context to predict her movement, and accordingly the perception of the realistic robot would elicit an N400 effect indicating the violation of predictions, whereas the human and the mechanical robot would not. Our data confirmed this hypothesis suggesting that uncanny valley could be explained by violation of one's predictions about human norms when encountered with realistic but artificial human forms. Importantly, our results implicate that the mechanisms underlying perception of other individuals in our environment are predictive in nature. HIGHLIGHTSUncanny valley can be explained by violation of one's predictions about human norms.N400 ERP component can be used to assess the design quality of social robots.Mechanisms underlying perception of other individuals are predictive in nature.
Do comorbid anxiety disorders moderate the effects of psychotherapy for bipolar disorder? Results from STEP BD.
Venue: The American journal of psychiatry
Year: 2014

At least 50% of individuals with bipolar disorder have a lifetime anxiety disorder. Individuals with both bipolar disorder and a co occurring anxiety disorder experience longer illness duration, greater illness severity, and poorer treatment response. The study explored whether comorbid lifetime anxiety in bipolar patients moderates psychotherapy treatment outcome.  In the Systematic Treatment Enhancement Program randomized controlled trial of psychotherapy for bipolar depression, participants received up to 30 sessions of intensive psychotherapy (family focused therapy, interpersonal and social rhythm therapy, or cognitive behavioral therapy) or collaborative care, a three session comparison treatment, plus pharmacotherapy. Using the number needed to treat, we computed effect sizes to analyze the relationship between lifetime anxiety disorders and rates of recovery across treatment groups after 1 year.  A total of 269 patients (113 women) with a comorbid lifetime anxiety disorder (N=177) or without a comorbid lifetime anxiety disorder (N=92) were included in the analysis. Participants with a lifetime anxiety disorder were more likely to recover with psychotherapy than with collaborative care (66% compared with 49% recovered over 1 year; number needed to treat=5.88, small to medium effect) For patients without a lifetime anxiety disorder, there was no difference between rates of recovery in psychotherapy compared with collaborative care (64% compared with 62% recovered; number needed to treat=50, small effect) Participants with one lifetime anxiety disorder were likely to benefit from intensive psychotherapy compared with collaborative care (84% compared with 53% recovered; number needed to treat=3.22, medium to large effect) whereas patients with multiple anxiety disorders exhibited no difference in response to the two treatments (54% compared with 46% recovered; number needed to treat=12.5, small effect)  Depressed patients with bipolar disorder and comorbid anxiety may be in particular need of additional psychotherapy for treating acute depression. These results need to be replicated in studies that stratify bipolar patients to treatments based on their anxiety comorbidity status.
Decorrelated Double Q learning
Venue: ArXiv
Year: 2020

Q learning with value function approximation may have the poor performance because of overestimation bias and imprecise estimate. Specifically, overestimation bias is from the maximum operator over noise estimate, which is exaggerated using the estimate of a subsequent state. Inspired by the recent advance of deep reinforcement learning and Double Q learning, we introduce the decorrelated double Q learning (D2Q) Specifically, we introduce the decorrelated regularization item to reduce the correlation between value function approximators, which can lead to less biased estimation and low variance. The experimental results on a suite of MuJoCo continuous control tasks demonstrate that our decorrelated double Q learning can effectively improve the performance.
The aesthetic treatment for anterior teeth with lost crown by endorestoration
Year: 2009

The aesthetic has an important role in social life, especially the anterior teeth. The aesthetic abnormality of anterior teeth i.e. discoloration, malpotition or the anterior teeth with crown damage for more than one third or all part of crown is lost due to caries or other causes, will influence its appearance especially during smile.  The aim of this case report, therefore, is to show how teeth with clinical crown lost or only the root left still can be treated by endorestoration treatment in order to reconstruct the shape and function of the teeth similar to the original ones.  Female 52 years old with the lost crown of anterior teeth. The patient did not want her teeth to be extracted.  The abnormality of these teeth are still able to be reconstructed by endorestoration i.e. endodontic treatment with post and core insertion in the root canal will increase its retention and recovery by the porcelain crown fused to metal to recover the original formation and aesthetic and thus has the normal refunction. The treatment, it improve the confidence of the patient, and also can function normally. The patient did not feel pain. Ronsenography showed the periapical lesion diminished, the neighbor gingival was going better in both function and color.  Endorestoration treatment on the anterior teeth with lost crown could recover the normal function, dental aesthetic and self confidence.
One step novel synthesis of CoFe2O4/graphene composites for organic dye removal
Venue: Journal of Sol Gel Science and Technology
Year: 2019

present study was adopted for synthesis of CoFe2O4/graphene nanocomposites via facile, environment friendly and novel in situ reduction auto combustion sucrose route. The graphene based materials as well as the obtained nanocomposites were characterized using X ray diffraction (XRD) transmission electron microscopy (TEM) differential thermal analysis thermogravimetry (DTA TG) and vibrating sample magnetometry (VSM) measurements. These measurements confirmed the formation of densely distributed CoFe2O4 nanoparticles on graphene nanosheets when the reduction of graphene oxide (GO) component was carried out through reflux. On the other hand, when the process was carried out without reflux, the in situ reduction of GO during ferrite auto combustion resulted in the formation of uniformly distributed CoFe2O4 nanoparticles on reduced graphene oxide (rGO) nanosheets. The changes in the thermal stability of the prepared graphene and their ferrite nanoncomposites was discussed in the view of exposed surface area and ferrite's agglomeration phenomena. The obtained nanocomposites were examined for the adsorption/removal of toxic malachite green (MG) dye from aqueous media depending on their magnetic sensitivity besides their porous surface morphology.

NATIONAL LANGUAGE POLICY IN THE BSSR (1920 early 1930's) AND ITS INFLUENCE ON THE PROFILE OF POLISH LANGUAGE
Year: 2018

National language policy in the 1920s and early 1930s had a major impact on the ratio of the socio communicative system components of the BSSR in the period under review. The article reveals the functional distribution of idioms, determines the legal status and public functions of the Polish language as one of the components of the social and communicative system. The use of the method of sociolinguistic interpretation of written sources made it possible to define that the functional distribution of the official languages of the BSSR (Belarusian, Jewish, Russian and Polish) mainly reflects the numerical proportions of the population of the BSSR by nationality. The actual status of the languages corresponded to their legal status which allowed the languages of the main nationalities, including the Polish language, to function in the most important spheres of communication.

The Vanishing Slave: Publishing the Narrative of Charles Ball, from Slavery in the United States (1836) to Fifty Years in Chains (1858)
Venue: The Papers of the Bibliographical Society of America
Year: 2017

O 5 January 1838 the abolitionist and leader of the American AntiSlavery Society (AASS) Theodore Weld wrote to Sarah and Angelina Grimke: "We have half a dozen fugitives from southern slavery now in the city just arrived here all together. Two of them are exceedingly interesting cases. One a man of thirty whose history is as rife with the highest interest as Charles Ball." Weld made reference to the former slave Charles Ball by way of introducing a fugitive slave lately arrived in New York, James Williams, whose narrative the AASS would publish a few weeks later. The comparison between Ball and Williams reveals that at one moment of their publishing history, the two slaves' narratives, respectively Slavery in the United States: A Narrative of the Life and Adventures of Charles Ball, a Black Man (1836) and Narrative of James Williams,
The influence of the crevice induced IR drop on polarization measurement of localized corrosion behavior of 316L stainless steel
Venue: Corrosion Science
Year: 2019

This paper evaluates the role of IR drop on initiation of the crevice corrosion of 316 L stainless steel in 3.5% NaCl solution. For this purpose, potentiodynamic and galvanostatic experiments and macroscopic/microscopic observations were implemented at crevice gaps of 30, 60, 120 and 240 mm. According to the results, two distinct stages of crevice corrosion of 316 L stainless steel were observed: crevice initiation and propagation. The crevice corrosion was found to be initiated by scattered pits without any significant IR drop. However, when the current increased due to pitting occurrence, the IR drop increased considerably.
Modeling, Simulation and Control of the Walking of Biped Robotic Devices, Part II: Rectilinear Walking
Year: 2016

This is the second part of a three part paper. It extends to the free walking results of a previous work on postural equilibrium of a lower limb exoskeleton for rehabilitation exercises. A classical approach has been adopted to design gait (zero moment point (ZMP) linearized inverted pendulum theory, inverse kinematics obtained through the pseudo inverse of Jacobian matrices) While several ideas exploited here can be found in other papers of the literature, e.g. whole body coordination, our contribution is the simplicity of the whole control approach that originates logically from a common root. (1) The approximation of the unilateral foot/feet ground contacts with non holonomic constraints leads naturally to a modeling and control design that implements a two phase switching system. The approach is facilitated by Kane's method and tools as described in Part I. (2) The Jacobian matrix is used to transfer from the Cartesian to the joint space a greater number of variables for redundancy than the degrees of freedom (DOF) We call it the extended Jacobian matrix. Redundancy and the prioritization of postural tasks is approached with weighted least squares. The singularity of the kinematics when knees are fully extended is solved very simply by fake knee joint velocities. (3) Compliance with the contact and accommodation of the swing foot on an uneven ground, when switching from single to double stance, and the transfer of weight from one foot to the other in double stance are approached by exploiting force/torque expressions returned from the constraints. (4) In the center of gravity (COG)/ZMP loop for equilibrium, an extended estimator, based on the linearized inverted pendulum, is adopted to cope with external force disturbances and unmodeled dynamics. Part II treats rectilinear walking, while Part III discusses turning while walking.
Rural restructuring in China: Theory, approaches and research prospect
Venue: Journal of Geographical Sciences
Year: 2017

Rural restructuring is a process of reshaping socio economic morphology and spatial pattern in rural territory in response to the changes of elements both in kernel system and external system of rural development, by optimally allocating and efficiently managing the material and non material elements in the two systems. It aims at ultimately optimizing the structure and promoting the function within rural territorial system as well as realizing the coordination of structure and complementation of function between urban and rural territorial system. This paper establishes a theoretical framework of rural restructuring through elaborating the concept and connotations as well as analyzing the mechanism pushing forward rural restructuring based on the evolution of "elements structure function" and probes the approaches from the three aspects of spatial restructuring, economic restructuring and social restructuring. Besides, the authors argue that the study of rural restructuring in China in the future needs to focus on the aspects of long term and multi scale process and pattern, mechanism, regional models, rural planning technology system and standard, policy and institutional innovations concerning rural restructuring as well as the impacts of globalization on rural restructuring, in order to serve the current national strategic demands and cope with the changes of rural development elements in the process of urban rural development transformation.

Lost in Translation: The Gap in Scientific Advancements and Clinical Application
Venue: Front. Bioeng. Biotechnol.
Year: 2016

The evolution of medicine and medical technology hinges on the successful translation of basic science research from the bench to clinical implementation at the bedside. Out of the increasing need to facilitate the transfer of scientific knowledge to patients, translational research has emerged. Significant leaps in improving global health, such as antibiotics, vaccinations, and cancer therapies, have all seen successes under this paradigm, yet today, it has become increasingly difficult to realize this ideal scenario. As hospital revenue demand increases, and financial support declines, clinician protected research time has been limited. Researchers, likewise, have been forced to abandon time and resource consuming translational research to focus on publication generating work to maintain funding and professional advancement. Compared to the surge in scientific innovation and new fields of science, realization of transformational scientific findings in device development and materials sciences has significantly lagged behind. Herein, we describe: how the current scientific paradigm struggles in the new health care landscape; the obstacles met by translational researchers; and solutions, both public and private, to overcoming those obstacles. We must rethink the old dogma of academia and reinvent the traditional pathways of research in order to truly impact the health care arena and ultimately those that matter most: the patient.
Behind the ratings: Text mining of restaurant customers' online reviews
Year: 2018

Establishing the relation between online ratings and reviews provides a potentially inexpensive and effective way for restaurants to capture quality improvement hints from customers. To this end, this study proposes an integrated approach that leverages text mining and empirical modeling to quantitatively correlate ratings with reviews. From Dianping.com (a Chinese crowd sourced online review community) 49,080 pairs of restaurant rating and review were examined, with high frequency words, major topics, and subtopics identified. Multilinear regression was employed to screen out the most impactful factors that influence taste, environment, and service ratings. Managerially, the idea of triggering the synergistic benefit from customer ratings and reviews is referential for market practitioners both within and beyond the catering industry.
Piecewise optimal trajectories of observer for bearings only tracking of maneuvering target
Venue: 2018 IEEE Aerospace Conference
Year: 2018

This paper provides a general framework for optimizing the trajectory of an observer by means of bearings only tracking (BOT) in the case where the source is maneuvering. The basic problem of target motion analysis (TMA) is to estimate the trajectory of an object from noise corrupted sensor data. In the BOT context, the source state is only partially observed through nonlinear measurements, and the quality of the estimation strongly depends on the observer trajectory. We assume that the source has maneuvering capabilities, which is a case of practical interest though the TMA performance may be dramatically degraded. To characterize more precisely observer optimal maneuvers, we have to be able to determine the optimal course. To this purpose, the common approach consists in maximizing the determinant of the Fisher information matrix (FIM) by an iterative algorithm to obtain an optimal observer trajectory. In our framework, a cumulative sum of bearing rates and relative distance between the target and observer is used as reward function, and the chosen maneuver will be the one that maximizes the mathematical expectation of the reward function. The target's motion is quantized, and an extended Kalman filter is used to estimate the position and velocity of the target and to provide the initial distribution for each optimization period. The proposed algorithm is a closed loop control, and by maximizing the reward function, it allows to automatically compute the suboptimal maneuver. The applicability of our approach is demonstrated on realistic scenarios.
Essays on Agriculture, Misallocation, and Economic Development
Year: 2018

Author(s) Hang, Jing Advisor(s) Ohanian,  This dissertation consists of three chapters. This first chapter studies ability sorting between rural and urban regions induced by regional differences in prices and evaluates the importance of this mechanism in explaining the large rural urban (agriculture non agriculture) income gap in developing countries. The second chapter studies how capital deepening might help explain several development facts regarding agriculture when capital labor substitution is easier in agriculture than in non agriculture. The third chapter explores resource misallocation in production networks and studies how ignoring them might lead to mismeasured efficiency loss from misallocation.
