A Method for Automatically Building and Evaluating Dictionary Resources
A Method for Automatically Building and Evaluating Dictionary Resources Smaranda Muresan∗, Judith Klavansy ∗Computer Science Department, Columbia University 500 West 120th, New York, USA [email protected] yCenter for Research on Information Access, Columbia University 535 West 114th St, New York, USA [email protected] Abstract This paper describes a method toward automatically building dictionaries from text. We present DEFINDER, a rule-based system for extraction of definitions from on-line consumer-oriented medical articles. We provide an extensive evaluation on three dimensions: i) performance of the definition extraction technique in terms of precision and recall, ii) quality of the built dictionary as judged both by specialists and lay users, iii) coverage of existing on-line dictionaries. The corpus we used for the study is publicly available. A major contribution of the paper is the range of quantitative and qualitative evaluation methods. 1.

Biomedical Entity Representations with Synonym Marginalization
Biomedical Entity Representations with Synonym Marginalization Mujeen Sung Hwisang Jeon Jinhyuk Leey Jaewoo Kangy Korea University fmujeensung,j hs,jinhyuk lee,[email protected] Abstract Unlike named entities from general domain text, typical biomedical entities have several different Biomedical named entities often play impor- surface forms, making the normalization of biomed- tant roles in many biomedical text mining ical entities very challenging.

Microlymphatic Surgery for the Treatment of Iatrogenic Lymphedema
Microlymphatic Surgery for the Treatment of Iatrogenic Lymphedema Corinne Becker, MDa, Julie V. Vasile, MDb,*, Joshua L. Levine, MDb, Bernardo N. Batista, MDa, Rebecca M. Studinger, MDb, Constance M. Chen, MDb, Marc Riquet, MDc KEYWORDS Lymphedema Treatment Autologous lymph node transplantation (ALNT) Microsurgical vascularized lymph node transfer Iatrogenic Secondary Brachial plexus neuropathy Infection KEY POINTS Autologous lymph node transplant or microsurgical vascularized lymph node transfer (ALNT) is a surgical treatment option for lymphedema, which brings vascularized, VEGF-C producing tissue into the previously operated field to promote lymphangiogenesis and bridge the distal obstructed lymphatic system with the proximal lymphatic system. Additionally, lymph nodes with important immunologic function are brought into the fibrotic and damaged tissue. ALNT can cure lymphedema, reduce the risk of infection and cellulitis, and improve brachial plexus neuropathies. ALNT can also be combined with breast reconstruction flaps to be an elegant treatment for a breast cancer patient.

Analyzing At-Home Prosthesis Use in Unilateral Upper-Limb Amputees To

Analyzing At -Home Prosthesis Use in Unilateral Upper -Limb Amputees to Inform Treatment & Device Design Adam J. Spiers, Member, IEEE, Linda Resnik, and Aaron M. Dollar, Senior Member, IEEE Abstract — New upper limb prosthetic devices are continuously being developed by a variety of industrial, academic, and hobbyist groups. Yet, little research has evaluated the long term use of currently available prostheses in daily life activities, beyond laboratory or survey studies. We seek to objectively measure how experienced unilateral upper limb prosthesis-users employ their prosthetic devices and unaffected limb for manipulation during everyday activities. In particular, our goal is to create a method for evaluating all types of amputee manipulation, including non-prehensile actions beyond conventional grasp functions, as well as to examine the relative use of both limbs in unilateral and bilateral cases. This study employs a head-mounted video camera to record participant’s hands and arms as they Figure 1: A video screenshot from the head-mounted camera (for complete unstructured domestic tasks within their own homes. participant P2).

Coprolites of Deinosuchus and Other Crocodylians from the Upper Cretaceous of Western Georgia, Usa
Milàn, J., Lucas, S.G., Lockley, M.G. and Spielmann, J.A., eds., 2010, Crocodyle tracks and traces. New Mexico Museum of Natural History and Science, Bulletin 51. 209 COPROLITES OF DEINOSUCHUS AND OTHER CROCODYLIANS FROM THE UPPER CRETACEOUS OF WESTERN GEORGIA, USA SAMANTHA D. HARRELL AND DAVID R. SCHWIMMER Department of Earth and Space Sciences, Columbus State University, Columbus, GA 31907 USA, [email protected] Abstract—Associated with abundant bones, teeth and osteoderms of the giant eusuchian Deinosuchus rugosus are larger concretionary masses of consistent form and composition. It is proposed that these are crocodylian coprolites, and further, based on their size and abundance, that these are coprolites of Deinosuchus. The associated coprolite assemblage also contains additional types that may come from smaller crocodylians, most likely species of the riverine/estuarine genus Borealosuchus, which is represented by bones, osteoderms and teeth in fossil collections from the same site. INTRODUCTION The Upper Cretaceous Blufftown Formation in western Georgia contains a diverse perimarine and marine vertebrate fauna, including many sharks and bony fish (Case and Schwimmer, 1988), mosasaurs, plesio- saurs, turtles (Schwimmer, 1986), dinosaurs (Schwimmer et al., 1993), and of particular interest here, abundant remains of the giant eusuchian crocodylian Deinosuchus rugosus (Schwimmer and Williams, 1996; Schwimmer, 2002). Together with bite traces attributable to Deinosuchus (see Schwimmer, this volume), there are more than 60 coprolites recov- ered from the same formation, including ~30 specimens that appear to be of crocodylian origin. It is proposed here that the larger coprolites are from Deinosuchus, principally because that is the most common large tetrapod in the vertebrate bone assemblage from the same locality, and it is assumed that feces scale to the producer (Chin, 2002). -

Glossary of Key Terms and Concepts Related to the COVID-19 Pandemic
Glossary of Key Terms and Concepts Related to the COVID-19 Pandemic Asymptomatic: Defined by the National Library of Medicine as individuals who do not have symptoms of an illness or disease. Asymptomatic individuals include those who have been infected with a disease but are not showing symptoms or those who have recovered from a disease. In the case of COVID-19, recent studies show that infected individuals without symptoms can spread the disease to others. Close contact is defined by the CDC as “a) being within approximately 6 feet (2 meters) of a COVID-19 case for a prolonged period of time; close contact can occur while caring for, living with, visiting, or sharing a healthcare waiting area or room with a COVID-19 case, or b) having direct contact with infectious secretions of a COVID-19 case (e.g., being coughed on).” Coronavirus: “Coronaviruses are a large family of viruses which may cause illness.” They are named for the crown-like spikes on their surface. Several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.” WHO and CDC. COVID-19: COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This novel (new) coronavirus was first reported in China in December 2019. The World Health Organization announced COVID-19 as the official name of the disease in February 2020. Other names used to refer to COVID-19 include SARS-CoV-2 and 2019-nCoV. -
