Reversing The Twenty Questions Game

Twenty questions is a widely popular verbal game. In recent years, many computerized versions of this game have been developed in which a user thinks of an entity and a computer attempts to guess this entity by asking a series of boolean-type (yes/no) questions. In this research, we aim to reverse this game by making the computer choose an entity at random. The human aims to guess this entity by quizzing the computer with natural language queries which the computer will then attempt to parse using a boolean question answering model. The game ends when the human is successfully able to guess the entity of the computer's choice.Comment: 14 pages, 9 figures, 2 tables, This paper is a graduate course project for North Carolina State University, written for the Natural Language Processing class in Fall 2021.

A rare case of serologically diagnosed overlap syndrome presents as an idiopathic inflammatory myositis without any overlapping features

Overlap syndrome is a rare inflammatory rheumatic condition that shares features suggestive of at least two distinct autoimmune diseases with a reported prevalence of less than 34/100,000 persons and an incidence of less than 20/million/year. One example of an overlap syndrome is the presence of dermatomyositis or polymyositis with other autoimmune afflictions such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), or Sjogren’s syndrome. We present a case report of a 22-year-old male presented with progressive weakness in both upper and lower limbs without any other significant complaints. On investigation, serology revealed antibodies suggestive of overlap syndrome, which on further investigations, categorized as idiopathic inflammatory myositis (IIM). This shows that overlap syndrome, as an IIM, is one of the differential diagnoses in patients presenting with progressive extremity weakness involving both extremities even if there is no involvement of any sensory function

Triple mesh technique in repair of recurrent lumbar incisional hernia

Lumbar hernias occur infrequently and can be congenital, primary (inferior or Petit type, and superior or Grynfeltt type), post-traumatic, or incisional. They are bounded by the 12th rib, the iliac crest, the erector spinae, and the external oblique muscle. Most postoperative incisional hernias occur in nephrectomy or aortic aneurysm repair incisions for which various surgical method in context of meshplasty are available. In this case 60 yr. male hypertensive patient presented to the outpatient clinic of institute with recurrent left side lumbar incisional hernia, patient was previously operated for left side nephrolithiasis 15 years back and onlay meshplasty 2 years back for incisional hernia. The patient was operated under high risk for recurrent incisional hernia repair by triple layered meshplasties in the same sitting. Lumbar incisional hernias are often diffuse with fascial defects that are usually hard to appreciate. Computed tomography scan is the diagnostic modality of choice with adjuvant clinical findings, which allows differentiating them from abdominal wall musculature denervation atrophy complicating flank incisions. Repairing these hernias is difficult due to the surrounding structures for which our surgical approach included a triple mesh repair consisting of underlay, inlay and onlay meshplasty thereby anticipating further such incidences of incisional hernia

Pancreatitis, panniculitis and polyarthralgia syndrome: A rare complication of pancreatic pathology

Pancreatitis, panniculitis, and polyarthralgia (PPP) syndrome is a rare complication of chronic pancreatitis and occurs due to leakage of pancreatic enzymes in the systemic vasculature. This enzyme leakage leads to multiple manifestations such as polyarthralgia, panniculitis, and bone necrosis due to tissue autodigestion. The inciting pancreatic pathology may be masked, and the presentation may be due to one of the systemic consequences of enzyme leakage, which can present as a diagnostic challenge for clinicians. Here we present a patient who presented with nodular lesions and bone necrosis, and was found to have PPP syndrome. Therefore, a proper understanding of pathophysiology and radiology findings can help with prompt diagnosis and early exploration of management options

Model of LPG Refrigerator: A Literature Review

This work investigates the result of an experimental study carried out to determine the Coefficient of performance of domestic refrigerator when a propane-butane mixture is liquefied petroleum gas (LPG) which is available and comprises 56.4% butane, 24.4%propane, and 17.2% isobutene. This paper also presented an experimental investigation of COP by the effect of changing capillary tube length, capillary tube inner diameter and capillary coil diameter on the mass flow rate of refrigerant in an adiabatic helical capillary tube. Large amount of electricity supply is not available easily in large part of underdevelopment country like India. It will also prove to be an effective for remote area such as research sites, mines, & deserts where electricity is generally not available. The LPG is cheaper and possesses an environmental free in nature with no ozone depletion potential (ODP). Also LPG is available as a side product in local refineries. The results of the present work indicate the successful use of this propane-butane mixture as an alternative refrigerant to CFCs and HFCs in domestic refrigerator. It would include Experimental setup of working model and detailed observation of the LPG refrigerator and represents its application in refinery, hotel, chemical industries where requirement of LPG is more.

Post-Operative Proximal Optic Nerve Diffusion Restriction: Optic Neuropathy or Central Retinal Artery Occlusion?

Central retinal artery occlusion (CRAO) is a neurovascular emergency and acute monocular visual loss should trigger a stroke code activation. As thrombolytic therapy is considered for non-arteritic CRAO in the stroke therapeutic window, we aimed to review all telestroke encounters for acute visual loss in Mayo Clinic national telestroke network, focusing on the ocular diagnosis and the management recommendations
