Method for calibration accuracy improvement of projector-camera-based structured light system (2017)

Calibration is a critical step for the projector-camera-based structured light system (SLS). Conventional SLS calibration means usually use the calibrated camera to calibrate the projector device, and the optimization of calibration parameters is applied to minimize the two-dimensional (2-D) reprojection errors. A three-dimensional (3-D)-based method is proposed for the optimization of SLS calibration parameters. The system is first calibrated with traditional calibration methods to obtain the primary calibration parameters. Then, a reference plane with some precisely printed markers is used for the optimization of primary calibration results. Three metric error criteria are introduced to evaluate the 3-D reconstruction accuracy of the reference plane. By treating all the system parameters as a global optimization problem and using the primary calibration parameters as initial values, a nonlinear multiobjective optimization problem can be established and solved. Compared with conventional calibration methods that adopt the 2-D reprojection errors for the camera and projector separately, a global optimal calibration result can be obtained by the proposed calibration procedure. Experimental results showed that, with the optimized calibration parameters, measurement accuracy and 3-D reconstruction quality of the system can be greatly improved.
Body Mass Index and Exercise Effort Influences Changes in Motor Symptoms After High-Cadence Dynamic Cycling in Parkinson's Disease (2022)

High-cadence dynamic cycling improves motor symptoms of Parkinson's disease (PD), such as tremor and bradykinesia. However, some participants experience greater benefits than others. To gain insight into how individual characteristics and cycling performance affects functional changes, data from two previous studies were used to build several preliminary predictive models. The purpose was to examine which variables contribute to greater improvement in symptoms after high-cadence dynamic cycling. We hypothesized that individuals with higher body mass index (BMI), increased age, more severe symptoms, and higher PD medication dosages were less likely to contribute effort during cycling. UPDRS-III was assessed before and after each session, and cadence and power were recorded every second. Entropy of cadence was calculated, and data were analyzed using analysis of variance and multiple linear regression. The multiple linear regression model of post UPDRS significantly (R<sup>2</sup> = 0.81, <i>p</i> < 0.001) explained its variance, with pre UPDRS as the main predictor (<i>p</i> < 0.0001). The binomial logistic model of mean effort did not significantly (R<sup>2</sup> = 0.36, <i>p</i> = 0.14) explain the variance. <i>Post-hoc</i> analysis found a significant (β = 0.28, <i>p</i> = 0.03) moderating effect of different levels of BMI on the association between mean effort and post UPDRS. These results suggest that BMI, effort, and baseline UPDRS levels can potentially predict individual responses to high-cadence dynamic cycling.
Estimation of Relative Direction Angle of Distant, Colliding Airplane in Sense-and-avoid and Tracking (2012)

Visual detection based sense and avoid problem is more and more &#13;\nimportant nowadays as UAVs are getting closer to entering &#13;\nremotely piloted or autonomously into the airspace. It is &#13;\ncritical to gain as much information as possible from the &#13;\nsilhouettes of the distant aircrafts. In our paper, we &#13;\ninvestigate the reachable accuracy of the orientation &#13;\ninformation of remote planes under different geometrical &#13;\ncondition, by identifying their wing lines from their detected &#13;\nwingtips. Under the assumption that the remote airplane is on a &#13;\nstraight course, the error of the spatial discretization &#13;\n(pixelization), and the automatic detection error is calculated.

Apoptosis as a Possible Way of Destruction of Lymphoblasts After Glucocorticoid Treatment of Children with Acute Lymphoblastic Leukemia (1994)

Apoptosis (programmed cell death) is a physiologic phenomenon wherein the dying cell plays an active part in its own destruction. It has an important role in regulation of the balance of cell proliferation and cell death. The pharmacologic manipulation of apoptosis offers new possibilities for the prevention and treatment of cancer. One of the independent prognostic factors in the treatment of acute lymphoblastic leukemia is the sensitivity of the leukemic cells to corticosteroids. Apoptosis after glucocorticoid therapy is suggested as a prognostic factor in children with leukemia. Peripheral blood of children with acute leukemia was taken for morphologic and flow cytometric studies before and after the onset of prednisolone monotherapy. In most of the cases a positive correlation was observed between the decrease of blast numbers and the increase in apoptotic ratio in peripheral blood. In one case no response was observed either clinically or regarding apoptosis.
Transfer Learning in Adaptive Filters: The Nearest Instance Centroid-Estimation Kernel Least-Mean-Square Algorithm (2017)

We propose a novel nearest-neighbors approach to organize and curb the growth of radial basis function network in kernel adaptive filtering (KAF). The nearest-instance-centroid-estimation (NICE) kernel least-mean-square (KLMS) algorithm provides an appropriate time-space tradeoff with good performance. Its centers in the input/feature space are organized by quasi-orthogonal regions for greatly simplified filter evaluation. Instead of using all centers to evaluate/update the function approximation at every new point, a linear search among the iteratively-updated centroids determines the partial function to be used, naturally forming locally-supported partial functionals. Under this framework, partial functionals that compose the adaptive filter are quickly stored/retrieved based on input, each corresponding to a specialized “spatial-band” subfilter. The filter evaluation becomes the update of one of the subfilters, creating a content addressable filter bank (CAFB). This CAFB is incrementally updated for new signal applications with mild constraints, always using the past-learned partial filter sums, opening the door for transfer learning and significant efficiency for new data scenarios, avoiding training from scratch as have been done since the invention of adaptive filtering. Using energy conservation relation, we show the sufficient condition for mean square convergence of the NICE-KLMS algorithm and establish the upper and lower bounds of steady-state excess-mean-square-error (EMSE). Simulations on chaotic time-series prediction demonstrate similar levels of accuracy as existing methods, but with much faster computation involving fewer input samples. Simulations on transfer learning using both synthetic and real-world data demonstrate that NICE CAFB can leverage previously learned knowledge to related task or domain.
Speed and balancing control for unicycle robot (2016)

Unicycle mobile robot is wheeled mobile robot that can stand and move around using one wheel. It has attached a lot of researchers to conduct studies about the system, particularly in the design of the system mechanisms and the control strategies. Unlike two wheel balancing mobile robot which mechanically stable on one side, unicycle mobile robot requires additional mechanisms to keep balancing robot on all sides. By assuming that both roll dynamics and pitch dynamics are decoupled, so the balancing mechanisms can be designed separately. The reaction wheel is used for obtaining balancing on the roll angle by rotating the disc to generate momentum. While the wheeled robot is used for obtaining balancing on the pitch angle by rotating wheel to move forward or backward. A PID controller is used as balancing control which will control the rotation motor on the reaction disc and wheel based on the pitch and roll feedback from the sensor. By adding the speed controller to the pitch control, the system will compensate automatically for perfectly center of gravity on the robot. Finally, the unicycle robot will be able to balance on pitch angle and roll angle. Based on simulation result validates that robot can balance using PID controller, while based on balancing pitch experiment result, robot can achieve balancing with maximum inclination about ±23 degree on pitch angle and ±3.5 degree on roll angle with steady state error 0.1 degree.
Framework for advancing equity in academic medicine and science: Perspectives from early career female faculty during the COVID-19 pandemic (2021)

Early-career female faculty, both physician scientists and basic researchers, have disproportionately experienced negative professional, financial, and personal consequences associated with the novel coronavirus disease 2019 (COVID-19) pandemic. This career phase represents a critical time for establishing a network of mentors and collaborators, demonstrating professional independence, and balancing new teaching, research, and service duties while simultaneously navigating personal and familial responsibilities. Persistent gender inequality perpetuated by adherence to traditional gender roles place early-career women faculty at a further disadvantage. Women in academic medicine and research do not attain promotion, leadership positions, and other established markers of success at the same rate as their male counterparts. This disparity was the impetus for the creation of a Recruitment and Retention action group within the Center for Women in Medicine and Science (CWIMS) at the University of Minnesota Medical School (UMN). This perspective piece is written from the viewpoint of a group of female-identifying early-career faculty participating in a career development program for early-stage and newly appointed faculty at UMN, sponsored by the Recruitment and Retention CWIMS action group and our Office of Faculty Affairs. We describe areas of stress exacerbated by the COVID-19 pandemic: work, financial, and work-life well-being, and propose an adapted diversity, equity and inclusion (DEI) model to guide the response to future challenges within a faculty competency framework. We offer recommendations based on the DEI-competency framework, including opportunities for lasting positive change that can emerge from this challenging moment of our collective history.
Low-cost EUV collector development: design, process, and fabrication (2007)

Cost of ownership (COO) is an area of concern that may limit the adoption and usage of Extreme Ultraviolet Lithography (EUVL). One of the key optical components that contribute to the COO budget is the collector. The collectors being fabricated today are based on existing x-ray optic design and fabrication processes. The main contributors to collector COO are fabrication cost and lifetime. We present experimental data and optical modeling to demonstrate a roadmap for optimized efficiency and a possible approach for significant reduction in collector COO. Current state of the art collectors are based on a Wolter type-1 design and have been adapted from x-ray telescopes. It uses a long format that is suitable for imaging distant light sources such as stars. As applied to industrial equipment and very bright nearby sources, however, a Wolter collector tends to be expensive and requires significant debris shielding and integrated cooling solutions due to the source proximity and length of the collector shells. Three collector concepts are discussed in this work. The elliptical collector that has been used as a test bed to demonstrate alternative cost effective fabrication method has been optimized for collection efficiency. However, this fabrication method can be applied to other optical designs as well. The number of shells and their design may be modified to increase the collection efficiency and to accommodate different EUV sources The fabrication process used in this work starts with a glass mandrel, which is elliptical on the inside. A seed layer is coated on the inside of the glass mandrel, which is then followed by electroplating nickel. The inside/exposed surface of the electroformed nickel is then polished to meet the figure and finish requirements for the particular shell and finally coated with Ru or a multilayer film depending on the angle of incidence of EUV light. Finally the collector shell is released from the inside surface of the mandrel. There are several potential cost and fabrication advantages to this process. There is flexibility in the choice of material for producing the mandrel - this allows for optimizing the cost of fabrication of the mandrel. Moreover, since the final surface and figure of the collector optic can be modified, after electroforming the optic, the mandrel, in principle does not have a limited lifetime. Finally, the mandrel provides mechanical support to the electroformed optic throughout the fabrication process, thereby reducing deformation of the optic during polishing and coating. The optical design, optimization of collection efficiency, fabrication and characterization results is discussed in this work.
Recurrent Shoulder Instability: Do Morbidity and Treatment Differ Based on Insurance? (2019)

Among patients undergoing surgery for traumatic anterior shoulder instability, patients with Medicaid had significantly more delayed care. Correspondingly, they reported a more extensive history of instability, were more likely to have severe bone loss, and required more invasive stabilization procedures.
THE ROLE OF CROSS-SHOCK POTENTIAL ON PICKUP ION SHOCK ACCELERATION IN THE FRAMEWORK OF FOCUSED TRANSPORT THEORY (2013)

The focused transport theory is appropriate to describe the injection and acceleration of low-energy particles at shocks as an extension of diffusive shock acceleration (DSA). In this investigation, we aim to characterize the role of cross-shock potential (CSP) originated in the charge separation across the shock ramp on pickup ion (PUI) acceleration at various types of shocks with a focused transport model. The simulation results of energy spectrum and spatial density distribution for the cases with and without CSP added in the model are compared. With sufficient acceleration time, the focused transport acceleration finally falls into the DSA regime with the power-law spectral index equal to the solution of the DSA theory. The CSP can affect the shape of the spectrum segment at lower energies, but it does not change the spectral index of the final power-law spectrum at high energies. It is found that the CSP controls the injection efficiency which is the fraction of PUIs reaching the DSA regime. A stronger CSP jump results in a dramatically improved injection efficiency. Our simulation results also show that the injection efficiency of PUIs is mass-dependent, which is lower for species with a higher mass. Additionally, the CSP is able to enhance the particle reflection upstream to produce a stronger intensity spike at the shock front. Lastly, we conclude that the CSP is a non-negligible factor that affects the dynamics of PUIs at shocks.

Spatial organization of evoked neuronal dynamics in 2D recurrent networks, with or without structured stimulation (2009)

Neuronal dynamics in the awake mammalian cortex are known to display highly irregular spiking activity and asynchronous firing patterns at the population level (AI regime). Many computational models have proposed simplified benchmarks to investigate information propagation in such regimes [1]. However, to allow explicit analytical analysis, most of them assume random connectivity within the network, no propagation delays and unstructured Poisson external input [2]. In particular, for AI regimes, these models do not exhibit any substantial spatial correlations [3]. In contrast, in biological V1, it has been observed that the large-scale dynamics produced by ongoing reverberation correspond to spatially structured activity maps characterized by distance-dependent correlations [4,5]. A realistic model of sensory neocortex should thus take into account the presence of intrinsic spatial correlation in order to study how this may interfere with structured correlation evoked by the sensory drive.
Minimally invasive redo-aortic valve replacement (2018)

Bioprosthetic aortic valves have been used with increasing frequency over the past two decades, often in relatively young patients who may eventually require aortic valve re-operations due to degeneration of the bioprosthesis. Growing experience with minimally invasive aortic valve replacement has prompted surgeons to use minimally invasive approaches also with redo operations for replacement of the aortic valve. This tutorial describes the operative steps for a minimally invasive redo replacement of the aortic valve through an upper ministernotomy. We demonstrate the surgical access, initiation of cardiopulmonary bypass, venting, and cardioplegia strategies. Special situations, such as how to approach patent coronary grafts, the small aortic annulus, and the use of sutureless or rapid deployment valves are demonstrated and discussed. The tutorial shows that minimally invasive redo aortic valve replacement is a safe, effective, and reproducible procedure.

Versatile and rapid microfluidics-assisted antibody discovery (2021)

Recent years have seen unparalleled development of microfluidic applications for antibody discovery in both academic and pharmaceutical research. Microfluidics can support native chain-paired library generation as well as direct screening of antibody secreting cells obtained by rodent immunization or from the human peripheral blood. While broad diversities of neutralizing antibodies against infectious diseases such as HIV, Ebola, or COVID-19 have been identified from convalescent individuals, microfluidics can expedite therapeutic antibody discovery for cancer or immunological disease indications. In this study, a commercially available microfluidic device, Cyto-Mine, was used for the rapid identification of natively paired antibodies from rodents or human donors screened for specific binding to recombinant antigens, for direct screening with cells expressing the target of interest, and, to our knowledge for the first time, for direct broad functional IgG antibody screening in droplets. The process time from cell preparation to confirmed recombinant antibodies was four weeks. Application of this or similar microfluidic devices and methodologies can accelerate and enhance pharmaceutical antibody hit discovery.
Syntheses of polycyclic‐1,4‐dithiines and related heterocycles (1992)

Abstract Reactions of dihalogenoquinones or dihalogenoquinoxalines with thioamides gave the corresponding 1,4‐dithiines in high yields. Many of polycyclic 1,4‐dithiin derivatives can be synthesized by the reactions of dihalogenoheterocycles with thioamides, and they are useful as pigments and functional materials for electro‐optical applications. Some of heteroaromatic‐1,4‐dithiins formed an intermolecular charge‐transfer (CT) complex with a π‐acceptor such as TCNQ, and they are useful as π‐donors for CT complex.

Querying phenotype-genotype relationships on patient datasets using semantic web technology: the example of cerebrotendinous xanthomatosis (2012)

This work demonstrates how semantic web technologies can be used to support flexible representation and computational inference mechanisms required to query patient datasets at different levels of abstraction. The open world assumption is especially good for describing only partially known phenotype-genotype relationships, in a way that is easily extensible. In future, this type of approach could offer researchers a valuable resource to infer new data from patient data for statistical analysis in translational research. In conclusion, phenotype description formalization and mapping to clinical data are two key elements for interchanging knowledge between basic and clinical research.
