What Is It Like to Be a Bat-Author? Viktor Pelevin's Empire V
No full textIn this paper, Viktor Pelevin's novel Empire V (2006) is analysed, with its main concern with the status of language, in fiction as well as in contemporary Russian culture. The work is seen as a kind of sequel to Generation 17: whereas that novel predominantly focused on the problem of consciousness, its problematical relation with reality, but expressed this problem in language, in Empire V the problem of language as the form of consciousness is foregrounded; inevitably thus the status of the text we are reading and the relation it has to its author is problematized - as is the relation it has to its reader. It is a text that reflects on what language, its material, does. The possibility is suggested that this novel tries to rind a way out of postmodernism's anxieties about the conscious personality being an illusion, created by his own language.</p

From Sander to Schiavo: Morality, Partisan Politics, and America’s Culture War over Euthanasia, 1950–2010
No full textThe article discusses cultural conflicts and social policies regarding euthanasia in the United states from 1950 to 2010. The author highlights high-profile legal cases related to euthanasia including, the trial of Dr. Herman Sander, the first U.S. physician to stand trial for euthanasia, the case surrounding the termination of coma-patient Terri Schiavo's life support, and the trial of physician Jack Kevorkian. Other topics discussed include the impact of moral activism on politics, U.S. President Ronald Reagan's views on euthanasia, and the U.S. Supreme Court's rulings in euthanasia cases
Developing an ICD-10 Coding Assistant:Pilot Study Using RoBERTa and GPT-4 for Term Extraction and Description-Based Code Selection
No full textBACKGROUND: The International Classification of Diseases (ICD), developed by the World Health Organization, standardizes health condition coding to support health care policy, research, and billing, but artificial intelligence automation, while promising, still underperforms compared with human accuracy and lacks the explainability needed for adoption in medical settings. OBJECTIVE: The potential of large language models for assisting medical coders in the ICD-10 coding was explored through the development of a computer-assisted coding system. This study aimed to augment human coding by initially identifying lead terms and using retrieval-augmented generation (RAG)-based methods for computer-assisted coding enhancement. METHODS: The explainability dataset from the CodiEsp challenge (CodiEsp-X) was used, featuring 1000 Spanish clinical cases annotated with ICD-10 codes. A new dataset, CodiEsp-X-lead, was generated using GPT-4 to replace full-textual evidence annotations with lead term annotations. A Robustly Optimized BERT (Bidirectional Encoder Representations from Transformers) Pretraining Approach transformer model was fine-tuned for named entity recognition to extract lead terms. GPT-4 was subsequently employed to generate code descriptions from the extracted textual evidence. Using a RAG approach, ICD codes were assigned to the lead terms by querying a vector database of ICD code descriptions with OpenAI's text-embedding-ada-002 model. RESULTS: The fine-tuned Robustly Optimized BERT Pretraining Approach achieved an overall F1-score of 0.80 for ICD lead term extraction on the new CodiEsp-X-lead dataset. GPT-4-generated code descriptions reduced retrieval failures in the RAG approach by approximately 5% for both diagnoses and procedures. However, the overall explainability F1-score for the CodiEsp-X task was limited to 0.305, significantly lower than the state-of-the-art F1-score of 0.633. The diminished performance was partly due to the reliance on code descriptions, as some ICD codes lacked descriptions, and the approach did not fully align with the medical coder's workflow. CONCLUSIONS: While lead term extraction showed promising results, the subsequent RAG-based code assignment using GPT-4 and code descriptions was less effective. Future research should focus on refining the approach to more closely mimic the medical coder's workflow, potentially integrating the alphabetic index and official coding guidelines, rather than relying solely on code descriptions. This alignment may enhance system accuracy and better support medical coders in practice
Desain Rangka Mesin Bandsaw Dan Belt Sander
No full textProgress in the increasingly developing field of technology is an aspect of knowledge and technology that requires higher education to be able to increase their ability to master technology. The purpose of converting energy to machines is to help make human work easier. Plywood/wood cutting machine saw from manual becomes a useful machine for Bengkalis State Polytechnic students. The objectives are 1. To make it easier for the user when cutting plywood, 2. To find out the design process for the bandsaw machine frame and belt sander, 3. To know the planning procedures for the bandsaw machine frame design and belt sander. Study literature used by the author by looking for references related to design to create a project.
In this process, the authors designed a bandsaw and belt sander frame design where the design will be designed in such a way and function as a reference in the process of making the tool, this tool uses an unp iron frame 80 x 45 x 5 mm and hollow iron 30 x 30 x 1.8 mm by using a 1-phase electric motor and also using 2 wheels. This bandsaw saw machine is for cutting plywood and wood of small and large sizes. Belt sander for the sanding process after cutting which is a design with a scale of 1:100.

Single-channel 1.61 Tb/s optical coherent transmission enabled by neural network-based digital pre-distortion
No full textWe propose a novel digital pre-distortion (DPD) based on neural networks for high-baudrate optical coherent transmitters. We demonstrate experimentally that it outperforms an optimized linear DPD giving a 1.2 dB SNR gain in a 128GBaud PCS-256QAM single-channel transmission over 80km of standard single-mode fiber resulting in a record 1.61 Tb/s net data rate.Accepted Author ManuscriptTeam Sander Wahl
