Compiling high-level scripting languages to performant code
Get PDFThe popularity of data- and scientific-oriented applications, the abundance of on-demand compute resources, and the scarcity of domain expert programmers have given rise to high- level scripting languages. These high-level scripting languages offer a fast way to translate ideas into code, but tend to incur a heavy performance overhead. To alleviate the performance penalty, each implementation of these languages often offer a compilation path to a subset of the language.
In this thesis, we present the design and implementation of the Wolfram Language compiler, the production compiler for the Wolfram Language. We show how popular language features and runtime behavior, expected by Wolfram Language developers, are efficiently implemented within the compiler. We then show how the compiler provides a friction-less path to migrate programs from the interpreter to the compiler. We evaluate the compiler and show that the compiled code matches the performance of a highly tuned hand-written C code. Unlike existing techniques that compile a subset of the language, the compiler sup- ports the entirety of the Wolfram Language. We show why the compiler is a new model of development for programmers and showcase some applications of the compiler. The compiler has been released as a prominent feature of the Wolfram Engine, is readily available to developers, and is used by internal and external users to drive Wolfram Language features and implementations.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2022-08-01The student, Abdul Dakkak, accepted the attached license on 2020-07-16 at 15:01.The student, Abdul Dakkak, submitted this Dissertation for approval on 2020-07-16 at 15:06.This Dissertation was approved for publication on 2020-07-17 at 09:50.DSpace SAF Submission Ingestion Package generated from Vireo submission #15663 on 2020-10-02 at 15:51:21Made available in DSpace on 2020-10-07T22:50:02Z (GMT).

A massive benign prostate delivered intact: a case report
Get PDFBackground: Benign prostatic enlargement (BPH) is an age-related condition. Males above the age of 40 years commonly experience lower urinary tract symptoms (LUTS) related to the progressively growing prostate. BPH is coined by a deterioration in the quality of the patient`s life. Medicines along with advanced surgical procedures may not be suitable for treating oversized prostate glands.
Case presentation: A 84-years-old man presented to the urology clinic with severe LUTS that are getting worse over 2 years. He was never catheterized. Medicinal treatments failed to alleviate the symptoms. He has no past medical or surgical history of significance. Prostate ultrasonography revealed a huge prostate of 340cc. He underwent open prostatectomy and enjoyed an uneventful post-operative hospital stay. Histology showed a benign nodular prostatic hyperplasia.
Conclusion: This case presents one of the largest prostates reported in the literature

Worker falls with impalement by a steel bar that results in a penetrating scrotal injury: a case report
Get PDFBackground: Scrotal injuries constitute the great bulk of genito-urinary traumas. Penetrating scrotal injuries are infrequent when compared to blunts. Moreover, impalement injuries by hard metals are rarer, especially when no permanent harm is left.
Case presentation: A 38-year-old male construction site worker was brought to the accident and emergency (A&E) department after falling from a 3 meters-high building. On arrival, his look was horrific, as a large steel bar was penetrating his right chest causing pneumothorax. A second bar penetrated his scrotum from bottom to up. The patient was frightened by the accident. Vitals were normal, with no signs of major blood loss. The chest trauma was dealt with by the relevant team, while the scrotal injury necessitated emergency surgery. Operatively, the steel bar was found to travel miraculously across the scrotal contents sparing vital structures. Subsequently, the bar was removed leaving no permanent damage. The patient was discharged home uneventfully.
Conclusion: A steel bar might cause an eerily external genital injury that passes throughout the scrotum without notable content damage

The effects of laparoscopic adjustable gastric band (LAGB) placement on upper gastrointestinal tract function in obese adolescents are unknown. Therefore, our aim was to determine the short-term effects of LAGB on esophageal motility, gastroesophageal reflux, gastric emptying, appetite-regulatory hormones, and perceptions of post-prandial hunger and fullness.
Methods
This study was part of a prospective cohort study (March 2009–December 2015) in one tertiary referral hospital. The study included obese adolescents (14–18 years) with a body mass index (BMI) > 40 (or ≥ 35 with comorbidities). Gastric emptying was assessed by 13C-octanoic acid breath test, pharyngeal, and esophageal motor function by high-resolution manometry with impedance (HRIM), and appetite and other perceptions using 100-mm visual analogue scales. Dysphagia symptoms were scored using a Dakkak questionnaire. Data were compared pre- and post-LAGB placement and at a 6-month follow-up.
Results
Based upon analysis of 15 adolescents, at the 6-month follow-up, LAGB placement: (i) led to a significant reduction in weight and BMI; (ii) increased fullness and decreased hunger post-meal; (iii) increased symptoms of dysphagia after solid food; and, despite these effects, (iv) caused little or no changes to appetite hormones, while (v) effects on gastric emptying, esophageal motility, esophageal bolus transport, and esophageal emptying were not significant.
Conclusion
In adolescents, LAGB improved BMI and altered the sensitivity to nutrients without significant effects on upper gastrointestinal tract physiology at the 6-month follow-up
Developing institutional capacity for reproductive health in humanitarian settings: A descriptive study

Introduction. Institutions play a central role in advancing the field of reproductive health in humanitarian settings (RHHS), yet little is known about organizational capacity to deliver RHHS and how this has developed over the past decade. This study aimed to document the current institutional experiences and capacities related to RHHS. Materials and Methods. Descriptive study using an online questionnaire tool. Results. Respondents represented 82 institutions from 48 countries, of which two-thirds originated from low-and middle-income countries. RHHS work was found not to be restricted to humanitarian agencies (25%), but was also embraced by development organizations (25%) and institutions with dual humanitarian and development mandates (50%). Agencies reported working with refugees (81%), internally-displaced (87%) and stateless persons (20%), in camp-based settings (78%), and in urban (83%) and rural settings (78%). Sixtyeight percent of represented institutions indicated having an RHHS-related policy, 79% an accountability mechanism including humanitarian work, and 90% formal partnerships with other institutions. Seventy-three percent reported routinely appointing RH focal points to ensure coordination of RHHS implementation. There was reported progress in RHHSrelated disaster risk reduction (DRR), emergency management and coordination, delivery of the Minimum Initial Services Package (MISP) for RH, comprehensive RH services in post-crisis/recovery situations, gender mainstreaming, and community-based programming. Other reported institutional areas of work included capacity development, program delivery, advocacy/policy work, followed by research and donor activities. Except for abortion-related services, respondents cited improved efforts in advocacy, capacity development and technical support in their institutions for RHHS to address clinical services, including maternal and newborn health, sexual violence prevention and response, HIV prevention, management of sexually-transmitted infections, adolescent RH, and family planning. Approximately half of participants reported that their institutions had experienced an increase in dedicated budget and staff for RHHS, a fifth no change, and 1 in 10 a decrease. The Interagency RH Kits were reportedly the most commonly used supplies to support RHHS implementation. Conclusion. The results suggest overall growth in institutional capacity in RHHS over the past decade, indicating that the field has matured and expanded from crisis response to include RHHS into DRR and other elements of the emergency management cycle. It is critical to consolidate the progress to date, address gaps, and sustain momentum
