    Get PDF
    Forced sterilization in Black women has been an act of reproductive injustice since the abolishment of slavery. From forced surrogacy in Black slave women to forcibly sterilizing free Black women, there has been control over Black women\u27s reproductive rights for years. With roots in slavery and lingering pieces of it in today\u27s society, forced sterilization is an injustice to never be forgotten when it comes to the experiences of Black women

    Projection of Stabilized Aerial Imagery Onto Digital Elevation Maps for Geo-Rectified and Jitter-Free Viewing

    Get PDF
    As imagery is collected from an airborne platform, an individual viewing the images wants to know from where on the Earth the images were collected. To do this, some information about the camera needs to be known, such as its position and orientation relative to the Earth. This can be provided by common inertial navigation systems (INS). Once the location of the camera is known, it is useful to project an image onto some representation of the Earth. Due to the non-smooth terrain of the Earth (mountains, valleys, etc.), this projection is highly non-linear. Thus, to ensure accurate projection, one needs to project onto a digital elevation map (DEM). This allows one to view the images overlaid onto a representation of the Earth. A code has been developed that takes an image, a model of the camera used to acquire that image, the pose of the camera during acquisition (as provided by an INS), and a DEM, and outputs an image that has been geo-rectified. The world coordinate of the bounds of the image are provided for viewing purposes. The code finds a mapping from points on the ground (DEM) to pixels in the image. By performing this process for all points on the ground, one can "paint" the ground with the image, effectively performing a projection of the image onto the ground. In order to make this process efficient, a method was developed for finding a region of interest (ROI) on the ground to where the image will project. This code is useful in any scenario involving an aerial imaging platform that moves and rotates over time. Many other applications are possible in processing aerial and satellite imagery

    One Year Incidence of Infection in Pediatric Intestine Transplantation

    Background: This study reports the infection rate, location of infection, and pathogen causing bacterial, fungal, or viral infections in intestine transplant recipients at a pediatric transplant center. Methods: Records from a pediatric center were reviewed for patients receiving an intestine transplant. Positive cultures and pathology reports were used to diagnose bacterial, fungal, and viral infections and also to determine location and infectious agent. Risk for infection was assessed based on liver or colon inclusion, and immunosuppression induction, as part of the intestine transplant. Results: During the study period 52 intestine transplants were performed on 46 patients. Bacterial, fungal, and viral infection rates were 90%, 25%, and 75%, respectively. Enterococcus (non-vancomycin resistant enterococci (VRE)) species were the most common pathogens and were isolated from 52% of patients. VRE was present in 12% of transplant recipients. Candida species were the most common fungal pathogens (23% of patients). Respiratory viral infections were common (44%) and cytomegalovirus infection rate was 17%. Common sites of infection were bloodstream, urinary, and upper respiratory tract. Colon and liver inclusion in the transplant graft was not associated with increased risk of infection, nor was addition of rituximab to the immunosuppression induction protocol. Conclusion: Post-intestine transplant infections are ubiquitious in the pediatric population, including high rates of infection from bacterial, viral and fungal sources. Inclusion of the liver and/or colon as a component of the transplant graft did not appear to greatly impact the infectious risk. Adding rituximab to the immunosuppression induction protocol did not impact on infectious risk

    Gender effect on clinical features of achalasia: a prospective study

    BACKGROUND: Achalasia is a well-characterized esophageal motor disorder but the rarity of the disease limits performing large studies on its demographic and clinical features. METHODS: Prospectively, 213 achalasia patients (110 men and 103 women) were enrolled in the study. The diagnosis established by clinical, radiographic, and endoscopic as well as manometry criteria. All patients underwent a pre-designed clinical evaluation before and within 6 months after the treatment. RESULTS: Solid dysphagia was the most common clinical symptom in men and women. Chest pain was the only symptom which was significantly different between two groups and was more complained by women than men (70.9% vs. 54.5% P value= 0.03). Although the occurrence of chest pain significantly reduced after treatment in both groups (P < 0.001), it was still higher among women (32% vs. 20.9% P value= 0.04). In both sexes, chest pain did not relate to the symptom duration, LES pressure and type of treatment patients received. Also no significant relation was found between chest pain and other symptoms expressed by men and women before and after treatment. Chest pain was less frequently reported by patients over 56 yrs of age in comparison to those less than 56 yrs (p < 0.05). CONCLUSION: It seems that chest pain is the distinct symptom of achalasia which is affected by sex as well as age and does not relate to the duration of illness, LESP and the type of treatment achalasia patients receive

    Postā€intestine transplant graftā€versusā€host disease: Associated with inclusion of a liver graft and with a high mortality risk

    Introduction This study reports the incidence, anatomic location, and outcomes of graftā€versusā€host disease (GVHD) at a single active intestine transplant center. Methods Records were reviewed for all patients receiving an intestine transplant from 2003 to 2015. Pathology reports and pharmacy records were reviewed to establish the diagnosis, location, and therapeutic interventions for GVHD. Results A total of 236 intestine transplants were performed during the study period, with 37 patients (16%) developing GVHD. The median time to onset of disease was 83 days, with 89% of affected patients diagnosed in the first year postā€transplant. Mortality for affected patients was 54% in the oneā€year after GVHD diagnosis. Skin lesions were the most common manifestation of GVHD. Other sites of disease included lungs, bone marrow, oral mucosa, large intestine, and brain. The incidence of GVHD was 16% in adult patients, and slightly lower in pediatric recipients (13%). In adults, increasing graft volume (isolated versus multiā€organ) and liver inclusion were associated with increasing risk of GVHD, though this was not seen in pediatric patients. Conclusion Overall, 16% of intestine transplant recipients developed GVHD. GVHD is associated with high mortality, and disease in the lungs, brain, and bone marrow was universally fatal

    Constructing a Database from Multiple 2D Images for Camera Pose Estimation and Robot Localization

    Get PDF
    The LMDB (Landmark Database) Builder software identifies persistent image features (landmarks) in a scene viewed multiple times and precisely estimates the landmarks 3D world positions. The software receives as input multiple 2D images of approximately the same scene, along with an initial guess of the camera poses for each image, and a table of features matched pair-wise in each frame. LMDB Builder aggregates landmarks across an arbitrarily large collection of frames with matched features. Range data from stereo vision processing can also be passed to improve the initial guess of the 3D point estimates. The LMDB Builder aggregates feature lists across all frames, manages the process to promote selected features to landmarks, and iteratively calculates the 3D landmark positions using the current camera pose estimations (via an optimal ray projection method), and then improves the camera pose estimates using the 3D landmark positions. Finally, it extracts image patches for each landmark from auto-selected key frames and constructs the landmark database. The landmark database can then be used to estimate future camera poses (and therefore localize a robotic vehicle that may be carrying the cameras) by matching current imagery to landmark database image patches and using the known 3D landmark positions to estimate the current pose

    Automatic Calibration of an Airborne Imaging System to an Inertial Navigation Unit

    Get PDF
    This software automatically calibrates a camera or an imaging array to an inertial navigation system (INS) that is rigidly mounted to the array or imager. In effect, it recovers the coordinate frame transformation between the reference frame of the imager and the reference frame of the INS. This innovation can automatically derive the camera-to-INS alignment using image data only. The assumption is that the camera fixates on an area while the aircraft flies on orbit. The system then, fully automatically, solves for the camera orientation in the INS frame. No manual intervention or ground tie point data is required
