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.

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

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. Keywords: LPG refrigerator, domestic refrigerator, eco friendly refrigerants, Mixed Refrigerant

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

Unraveling the diversity, phylogeny, and ecological role of cryptic Coleopteran species of Vadodara district: a first comparative approach from India

Abstract Background More than 350 K described species, Coleoptera (beetles) represent the most diverse order from Class Insecta in the entire animal kingdom. However, their phylogeny is highly controversial due to their morphological crypticness and multiple markers used previously for sequence homology. Although many studies suggest that their diversity currently relies majorly on morphological analysis, nevertheless DNA barcodes may provide a functional, standardized tool for their unique identification. In the present report, a fragment of the mitochondrial cytochrome c oxidase I (COI) gene has been proposed as standard DNA barcoding marker for the identification of organisms. Result To evaluate this hypothesis, a random sampling was conducted in and around Vadodara, Gujarat, where 2690 individual of 65 species belonging to 16 families were reported from different sites, and diversity indices were employed to unravel the species composition of that habitat. Further, 12 beetles from dominant families were selected for sequence analysis using various bioinformatics tools and were compared with the rest of the beetles to obtain a more robust phylogeny which is not reported earlier in previous studies. Conclusion Hence, the present study suggests that Scarabaeidae tends to be more diverse in and nearby of Vadodara compared to all other families of Coleoptera and while in contrast Chrysomelidae showed maximum diversity of pest species. DNA barcoding and nucleotide analysis resolves the phylogeny of controversial taxa; (Adephaga(Gyrinidae+ (Dytiscidae++ Carabidae)) (Polyphaga(Histeridae+Buprestidae+Lampyridae+Elateridae+(Scarabaeidae+(Coccinelidae+ Apionidae+Curculionidae+ (Meloidae+Tenebrionidae+(Cerambycidae+Chrysomelidae))))))
