Tight Bounds on the Spooky Pebble Game: Recycling Qubits with Measurements
Authors: Kornerup Niels , Sadun Jonathan , Soloveichik David
Published: February 2025

Pebble games are popular models for analyzing time-space trade-offs. In particular, reversible pebble game strategies are frequently applied in quantum algorithms like Grover's search to efficiently simulate classical computation on inputs in superposition, as unitary operations are fundamentally reversible. However, the reversible pebble game cannot harness the additional computational power granted by intermediate measurements, which are irreversible. The spooky pebble game, which models interleaved Hadamard basis measurements and adaptive phase corrections, reduces the number of qubits beyond what purely reversible approaches can achieve. While the spooky pebble game does not reduce the total space (bits plus qubits) complexity of the simulation, it reduces the amount of space that must be stored in qubits. We prove asymptotically tight trade-offs for the spooky pebble game on a line with any pebble bound. This in turn gives a tight time-qubit tradeoff for simulating arbitrary classical sequential computation when using the spooky pebble game. For example, for all ϵ∈(0,1], any classical computation requiring time T and space S can be implemented on a quantum computer using only O(T/ϵ) gates and O(TϵS1−ϵ) qubits. This improves on the best known bound for the reversible pebble game with that number of qubits, which uses O(21/ϵT) gates. For smaller space bounds, we show that the spooky pebble game can simulate arbitrary computation with O(T1+ϵS−ϵ/ϵ) gates and O(S/ϵ) qubits whereas any simulation via the reversible pebble game requires Ω(S⋅(1+log⁡(T/S))) qubits.We also consider the spooky pebble game on more general directed acyclic graphs (DAGs), capturing fine-grained data dependency in computation. We show that for an arbitrary DAG even approximating the number of required pebbles in the spooky pebble game is PSPACE-hard. Despite this, we are able to construct a time-efficient strategy for pebbling binary trees that uses the minimum number of pebbles.

Authors:   , Pedroso Luísa de Lucchio , Arnez Maria Clara Freitas
Published: February 2025

O câncer é uma das principais causas de morte no mundo. Além das abordagens tradicionais, como a quimioterapia e cirurgia, novas opções terapêuticas têm surgido para o enfrentamento do câncer, entre elas a terapia com células CART. Diante disso, este estudo tem como objetivo analisar a evolução do uso das células CAR-T no tratamento do câncer, com foco em sua aplicação clínica no Brasil e suas implicações para o futuro no tratamento oncológico. Para tanto, utilizou-se como metodologia a revisão integrativa da literatura, com buscas de artigos na Biblioteca Virtual de Saúde no Portal de Periódicos Capes e na base de dados da PubMED, com publicações entre o ano de 2019 e 2024, no idioma português e inglês, com textos completos disponibilizados e que contribuíam para alcançar o objetivo deste estudo. Constatou-se que é possível afirmar que a terapia com células CAR-T trata-se de uma terapia promissora e que ganha espaço no cenário terapêutico de maneira significativa, inclusive no Brasil. Entretanto, demonstra-se eficaz nos casos de malignidades hematológicas, não havendo comprovação de sua eficácia em tumores sólidos. Faz-se necessário considerar que a terapia com células CAR-T representa uma revolução frente às terapias tradicionais, como a quimioterapia, mas que demanda atenção com os efeitos adversos causados pela sua aplicação.

Pacientes HIV positivos coinfectados com leishmaniose visceral: resposta imunológica e principais manifestações clínicas: uma revisão bibliográfica
Authors:   , Moreira Eduarda Luiza
Published: February 2025

O HIV é um vírus sexualmente transmissível que deteriora as células do sistema imunológico, enfraquecendo sua efetividade, abrindo espaço para a infecção de doenças oportunistas e causando a Síndrome de Imunodeficiência Adquirida (AIDS). Já a Leishmaniose é uma doença causada pela presença dos parasitas Leishmania no organismo, transmitida pela fêmea do mosquito Flebotomíneo em áreas rurais ou vegetações, fragilizando o sistema imunológico e causando variações crônicas em vísceras e pele. A coinfecção de HIV e Leishmania resulta em resposta imunológica comprometida, devido à depleção do sistema imune pelo HIV, deixando o corpo vulnerável à multiplicação do parasita. A apoptose de células imunológicas e aumento de citocinas inflamatórias comprometem o controle dos patógenos, causando progressão do HIV para a AIDS e possíveis recidivas mesmo após tratamento. Os homens são os mais afetados pela coinfecção, apresentando sintomas como esplenomegalia, hepatomegalia, febre, fraqueza e perda de peso. A maioria dos afetados são pardos, entre 20 e 49 anos, com evolução clínica positiva, mas com uma taxa de mortalidade de 16,6%, alta em comparação com outras coinfecções com o HIV.

Published: February 2025

Effective EQR is crucial to ensure audit quality. We conduct an experiment with a unique and experienced sample: 65 public company EQR partners. In contrast with the prior audit literature, we find that partners involved throughout the audit or who are subjected to a situation intended to increase conformity pressure are less likely to sign off on audits containing potentially material goodwill impairment issues, relative to EQR partners who are only involved at the end of an audit or who do not face additional pressure. We also describe the EQR process subsequent to changes in the regulatory environment and conduct exploratory analyses, which increase our understanding of how EQR is conducted in practice, factors important to EQR partners, and how EQR partner attributes moderate their responses to pressure. Our findings suggest that EQR partner involvement throughout the audit, along with several EQR partner attributes, can enhance audit quality.

Background and purpose: MyHealth is a new follow-up program including individual nurse-led sessions based on Guided Self-Determination (GSD), which has been shown to improve health and psychological outcomes in patients after treatment for breast cancer. Fidelity assessment is important to support the implementation of GSD in clinical practice. The purpose of this study was thus to investigate fidelity and acceptance of the GSD program in the MyHealth study and whether sociodemographic and psychological factors were associated with patients’ completion of the GSD program and completion of reflection sheets.
Material and methods: We assessed fidelity quantitatively by examining patients’ completion of the GSD program (i.e. ≥3 sessions), completion of the reflection sheets and their associations with sociodemographic and psychological factors among 239 patients, and nurse-reported acceptance qualitatively through a focus group interview with all five nurses providing the GSD program.
Results: A total of 81% of patients completed the GSD program, while 71% of the reflection sheets were completed. Including a relative in a GSD session and lower education were significantly associated with completion of the program. Younger age and including a relative in a GSD session were significantly associated with completion of reflection sheets. Nurses found GSD highly applicable and especially appreciated a values-clarifying GSD reflection sheet and the inclusion of a relative.
Interpretation: The GSD program was applied with moderate-to-high fidelity, and the inclusion of relatives is potentially valuable. The GSD program indicates high usability and potential for being translated into clinical practice.
A Brief Review of Wellbore Stability in Coal Beds: Technological Improvements and Challenges
Authors: N Jape , S Ghosh
Published: February 2025

Coal Bed methane is a vital energy resource and has been developing rapidly for the last two decades. Also, India's commitment to become a gas-based economy emphasizes more on increasing domestic gas production. Hence, there is a tremendous potential that can be exploited from coal bed gases. Wellbore stability is a critical factor throughout the life cycle of any well, particularly wherever coal formations are present in the subsurface, as coal beds possess several challenges mainly because of the low fracture gradient of coal and several natural fracture networks present in the coal beds. This review paper provides an overview of the factors influencing the wellbore stability of different types of wellbore modelling techniques, namely the analytical model, Poro-elastic model which is the most widely used technique and gives results with reasonable accuracy, Thermo-hydro-mechanical (THM) coupling model, and other numerical simulation techniques like finite element model used for calculating of and the stress distribution around the wellbore in the case of vertical and horizontal wells, as this is the crucial criterion for calculating fracture gradient. Amongst which, the THM coupling method is the most advanced modelling technique and is used when high thermal stresses are present. After this, it discusses the different drilling fluids used for drilling in the coal seams like oil based muds, degradable polymer based drilling fluids which have minimum formation damage and foam based drilling fluids which have efficient cuttings carrying capacity. Also, their limitations and advantages and the effects on permeability damage and tensile fractures caused by the drilling fluids. Thus, giving an overall review of the technological improvements in the CBM extraction processes.

Authors: A Ademola , D Oladele , R Trabelsi , H Trabelsi , F Boukadi
Published: February 2025

Alleviating production decline is a challenging task that every oil company will face at some point in the life of an oil reservoir. Enhanced Oil Recovery (EOR) techniques can be implemented to lessen the decline in the oil production rate and improve overall recovery. Despite water injection efforts in the Tanner field, production rate continues to fall, and reservoir pressure conditions have declined, making conventional primary and secondary recovery economically non-viable. This study evaluates the feasibility of Enhanced Oil Recovery (EOR) methods for a mature Tanner field. Four injection techniques—Continuous CO2 Injection, Water Alternating Gas (WAG), Carbonated Water Injection (CWI), and Alkaline Surfactant Polymer (ASP) were simulated in the reservoir model. The ECLIPSE simulator was employed to model EOR techniques on the reservoir from May 2000 to January 2021. Simulation results indicate that, Carbonated Water Injection with an injection pressure of 2000 psia returned the highest recovery factor of 28% OIIP and total oil production of 1.28MMstb. The highest FOE was observed during Carbonated Water Injection. The economic analysis of future performance revealed that CWI achieved the highest Net Present Value (NPV). Carbonated Water Injection (CWI) is considered the optimal EOR technique for the tanner field as it yields a higher NPV and the highest recovery factor. The novelty of this study lies in its evaluation of the feasibility of various EOR techniques, considering both technical and economic aspects. The findings hold significant implications for optimizing EOR strategies in mature fields.

Authors: Ortega Pabón José David , Flórez Zuluaga Jimmy Anderson , Hernández Lordui Mónica Patricia
Published: February 2025

Dado el creciente tráfico aéreo mundial, este articulo compara dos enfoques de autoencoders para la detección de anomalías en trayectorias aéreas, empleando el algoritmo DBSCAN como referencia inicial. El primer modelo utiliza características continuas normalizadas (latitud, longitud, velocidad y rumbo), mientras que el segundo incorpora una segmentación discreta del espacio aéreo mediante regiones de Voronoi, además de las variables cinemáticas. Los resultados indican una precisión para la detección de anomalías en promedio del 96% en el autoencoder continuo y del 97% en el modelo basado en Voronoi, con este último mostrando una mayor capacidad para identificar trayectorias normales. El análisis cualitativo demostró que los autoencoders, al incluir variables adicionales, capturan anomalías más complejas que DBSCAN. La integración de Voronoi mejoró la explicabilidad del modelo, facilitando la interpretación de las anomalías en su contexto geográfico.

Komu szumią te sosny i brzozy? Pamięć lokalna i historia miejsc straceń w Kosówce
Authors: Marcinkiewicz Stefan Michał
Published: February 2025

Near the village of Kosówka (Rajgród commune, Podlaskie Voivodeship) there are two execution sites from 1941‑1945. In the largest place (Kosówka I), a monument was erected in 1959 to commemorate Red Army soldiers, partisans, and prisoners of the concentration camp in Bogusze, Poles, Italians, French and Lithuanians. According to the act of establishing the monument, Soviet soldiers and Polish civilians are buried in this place. However, 292 Polish inhabitants of Grajewo and the surrounding area were shot by the Germans in another place (Kosówka II). Source research conducted by the author shows that Soviet prisoners of war – victims of Heydrich's order No. 8 regarding selection in camps – are buried at the first site. According to the post‑war investigation, approximately 5,000 Red Army soldiers of various nations and religions are buried in Kosówka. The monument inscription that is still present today results from the memory politics of the Polish People's Republic, which manipulated numbers and expanded the categories of victims. The inscription constitutes falsified, but also condensed knowledge about the past. It is a manifestation of the amalgamation of collective memory ‑ combining various events, threads, groups and people into one story about the past.
A correlative study of the clinical and radiographic signs of periodontal disease in dogs
Authors: Smith Mark M. , Zontine William J. , Willits Neil H.
Published: February 2025

Twenty-four dogs admitted for routine teeth cleaning were selected arbitrarily to undergo a periodontal examination and a dental radiographic examination before the dental procedure. Data pertaining to the physical and radiographic manifestations of periodontal disease of 783 teeth were collected. All dogs had lesions consistent with periodontal disease, ranging from mild gingivitis and minimal plaque accumulation to severely inflamed gingiva, exuberant calculus formation, and root exposure. Of the 783 teeth examined, 153 (20%) had a pocket depth ≥ 4 mm and ≤ 9 mm. Data regarding these teeth were subjected to statistical analysis. The clinical signs of plaque, calculus, mobility, pocket depth, and furcation were positively associated with radiographic signs of periodontal disease. The association between grossly evident gingivitis and radiographic signs of periodontal disease was not significant. Conditional probability analysis was applied to determine confidence intervals for the probability of a radiographic sign of periodontal disease occurring given that a clinical sign of periodontal disease occurs.
Intestinal decompression: Preliminary study in the horse
Authors: Beroza Gregory A. , Donawick William J. , Topkis Virginia A.
Published: February 2025

A technique of nasoduodenal (N-D) intubation and intestinal decompression was developed and used in the horse to explore the prevention of gastric and intestinal distention after abdominal surgical operation. Three styles of tubes (2 single-lumen tubes and 1 double-lumen tube) were positioned in the duodenum of 12 mature horses (10 experimental and 2 clinical) during laparotomy (without enterotomy), and an iatrogenic occlusion at the small intestine was created and later released in the 10 experimental horses. The 2 clinical horses had an exploratory laparotomy to correct a natural obstruction of the small intestine. After each horse recovered from surgical manipulation, suction was used to keep fluids from accumulating in the cranial part of the gastrointestinal tract. In 5 of the 12 horses, the most simple N-D tube was positioned successfully and functioned properly. Three of the 5 horses which were fasted before surgical manipulation (to obtain an empty stomach) survived without postsurgical complications. Volume of reflux material was measured. Clinical data, such as periods of comfort during decompression without giving analgesics, were recorded. Necropsies were done on 10 of the 12 horses (9 experimental and 1 clinical). Although already tested in 2 clinical horses, use of the N-D tube remains experimental, and the N-D tube functioned only in horses which were fasted before surgical manipulation. Perfection of a safe and dependable means of emptying the equine stomach of its solid ingesta before gastrointestinal intubation is done, is the next step in affording greater clinical application of the N-D tube for gastrointestinal decompression.
Deep Learning-based Image Recognition Technology in Medical Diagnosis
Authors: Wu Xia
Published: February 2025

In the context of the computer era, the system of deep learning and other intelligent algorithms to assist medical diagnosis is gradually applied in the diagnosis and treatment of medical clinical diseases. To further study the application value of intelligent algorithms in medical diagnosis, this paper analyzes the depth of deep learning algorithms. Then, for the needs of medical diagnosis, the network architecture of convolutional neural is improved on the basis of deep learning algorithms, and then the MobileNet V2 network model is constructed by using residual neural, and a distraction (SA) mechanism module is introduced for image recognition and classification. This paper presents a CAD medical diagnosis system that uses deep learning image recognition to facilitate its use in medical clinical diagnosis. The optimized network model in this paper achieves smooth accuracy and loss rate of approximately 0.975 left and -0.969 in training. Compared with other network models, the four indexes of frequency weight intersection and merger ratio (0.904), mean pixel accuracy (0.881), background intersection and merger ratio (0.941) and diagnostic region intersection and merger ratio (0.807) of this paper’s model are all optimal. The F1-score evaluation indexes for image recognition in all three lung diseases in this paper reached more than 97%, and the AUC was as high as 99%. At the same time, the sensitivity of the CAD system in this paper is much higher than that of other systems, and the image recognition algorithm, as well as the CAD system designed in this paper, can improve the diagnostic efficiency of the primary health care units, and it can provide a reference for the detection of diseases.
Research on Efficient Algorithms for Intelligent Computing in Big Data Analytics
Authors: Zhou Xiguo , Zhao Ziping , Gao Wentao
Published: February 2025

In this paper, we first collect massive data based on the Hadoop HDFS system and perform distributed data storage for it. Then, the massive data in the system is queried quickly by designing a secondary index and a parallel region query method based on Hilbert coding. Experiments are carried out to measure the efficiency of the Hadoop HDFS system in efficient data storage and querying, and to investigate its scalability. After completing the efficient storage and querying of data, the Spark DBSCAN algorithm is proposed to mine the data efficiently. The performance of the Spark DBSCAN algorithm is examined by comparing and analysing the clustering performance and running speed of the Spark DBSCAN algorithm with the traditional DBSCAN algorithm. The query performance of Hadoop HDFS is superior to that of Jena-Hbase and SHARD systems. The fast query time of Hadoop HDFS stays the same, and the scalability is nearly linear with the data size in the case of a slow query. The clustering accuracy of the Spark DBSCAN algorithm is slightly better than that of the traditional parallel DBSCAN algorithm, but the overall difference is small. The Spark DBSCAN algorithm runs significantly faster than the traditional parallel DBSCAN algorithm on different datasets.

he present paper deals with the analysis of the origin and peculiarities of formation of the names of clothes in modern Ossetian language. The paper considers identification of some mechanisms of formation of the leis of the semantic group under study in English. The investigation is performed with the material of distantly related languages — Ossetian and English. The methods used are: etymological, comparative, structural-seman­tic and dictionary definitions analysis. The material comprises words, formed mostly by compounding and affixation. The remarkable trait of the lexis is presence of hybrid lexical units built by semantic derivation. Semantic parallels are revealed with the help of Russian language. The lexis of the target semantic group partly originates from the parent language for both Ossetian and English — proto-Indo-European.

Recent decades have seen a drastic increase of academic interest in non-verbal communication of various ethnic groups. However, gestural behaviour of the Vietnamese, particularly in the sphere of etiquette, has been rarely analyzed by modern scholars. Research papers on this topic describe etiquette gestures of Vietnamese culture, especially bows, vaguely and sketchily. Although in the past bows were quite wide spread in Vietnam, nowadays the gesture seems to have lost its popularity. The goals of the paper are to analyze the descriptions of modern everyday Vietnamese bows, rules and situations of their use, in Vietnamese media. The objective of the research is to identify role and types of bows in modern Vietnamese culture. The results of the analyses show that bows, banned by the Vietnamese Communist Party several decades ago, are gradually starting to acquire more significance in modern society.

The article considers the representation of the interaction of perceptual and emotional spheres in the Russian language. The aim of the work is to identify intercepting cognitive areas and points of perceptual and emotional spheres based on the analysis of the compatibility of words describing the names of emotion representatives with perceptual features. To identify cognitive areas and points of intersection of perceptual and emotional spheres, a sample of contexts from the National Corpus of the Russian language, describing the names of representatives of emotions: soul, heart, mind, thoughts, memories, character, laughter, voice, tone, look, smile, joke, eyes, feelings, emotions, fear, love, hate, malice and others by means of perceptual features was studied. It was stated that synesthetic transference is based on a cognitive mechanism that regulates the rela­tions between different types of perception and the emotional sphere. The study showed that the cognitive areas of intersection of perceptual and emotional spheres in the Russian language are different in terms of fullness and the presence of asymmetric / sym­metrical utterances in the positive and negative evaluation zones. The most extensive cognitive area of intersection is tactile, fol­lowed by visual area, less extensive is gustatory / olfactory area and the narrowest area of intersection is auditory.
Semiotics of Discursive Interaction

This article is devoted to the problem of interaction of various discourses within the framework of media discourse. The author investigates the process of discourses’ interaction through signs and symbols. The purpose of the study is to analyze the linguistic signs used in a media text, belonging to different discourses and representing certain situations, which, thus, turn out to be juxtaposed. The author also analyzes the dominant components of the represented situations, which are also underlined due to the interaction between the signs of various discourses. During the study the methods of discourse analysis and semiotic analysis were used. The author comes to the conclusion that the interweaving of several situations (gastronomic, existential and television), their inclusion into a media communicative situation leads to poly-discursiveness — the presence of fragments of several discourses, represented by symbols. As a result of combining signs from various discourses in media discourse, a new reality is constructed — a new media situation, simultaneously consisting of several situations existing in different discourses.
Metaphorical Conceptualization in Multimodal Discourse (the Case Study of the Italian Television Show “Che tempo che fa”)

The paper highlights the results of studying the process of metaphorical conceptualization in the TV show discourse. The source of the material is the Italian TV show “Che tempo che fa” (eng. ‘What is the weather today’). The paper describes a num­ber of criteria for selecting interviews for conducting the re­search. In accordance with these criteria, video recordings of three interviews from two issues with a total duration of about 30 minutes have been selected. Special focus is laid on the methods of annotation and analysis of the ways of how verbal and nonverbal (gestural) means are interacted, as a result of which multimodal metaphors emerge. The systematization of the identified multimodal metaphors makes it possible to establish their main types and subtypes. According to the research findings, ges­tures in multimodal metaphors may not correspond to the verbal metaphor semantically or temporally. The latter testifies to such processes such as discoordination and asynchronization in the “word + gesture” dichotomy.

Bandung is an ancient lake area formed by years of sedimentation. The result of the sedimentation is then called the Bandung lacustrine soil where the soil has very soft characteristics, is water saturated, has relatively high voids, low shear strength and is very compressible. This study aims to determine the consolidation characteristics of Bandung Lacustrine soil in the Gedebage area using CPTu Test, Drill Test, SPT Test, Laboratory Test and settlement plate instrumentation. CPTu Test, Drill Test and SPT Test are intended to determine the layering and depth of the Bandung Lakustrine soil where the Bandung Lakustrine soil is at a depth of 5 - 30 m. Laboratory and Settlement Plate tests were conducted to determine the physical characteristics and consolidation of the Bandung Lakustrine soil. From this research, it is known that Bandung Lakustrin soil has high moisture content (Wn > 200%), high pore number value (e > 4), relatively high primary and secondary strain value (Cc = 2 - 4 & Ca = 0.005 - 0.09), and relatively high strain (12 - 54%), coefficient of consolidation (Cv) ranges from 2.49 - 16.18 x10-3 cm2/s based on CPTu dissipation data.

Published: February 2025

Slope stability is a crucial aspect in geotechnical engineering, especially in construction projects involving sloping land. This research addresses the slope stability stage with the application of a retaining wall, a structure that serves to prevent soil displacement and landslides. Slope modeling was performed using PLAXIS 8.6 software. For a slope with a grading of 1H:1.5V, a safety factor of 1.1760 was obtained. To improve stability, the slope was cut to 1H:1V, which gave a safety factor of 1.3720, which is considered safe only for temporary conditions. Furthermore, a temporary drainage system was implemented prior to retaining wall construction using bored piles designed to reach the andesite soil layer. After re-modeling the safety factor increased to 1.5258, indicating a suitable condition for the long term. The process ended with backfilling and implementation of a permanent drainage system. Based on Bowles (1993) and SNI 8460:2017 standards, the minimum safety factor for construction is 1.25 for minimum conditions and 1.3 for temporary conditions, and 1.5 for permanent conditions. The results showed that the application of retaining walls can significantly improve slope stability.

Stabilitas lereng merupakan aspek krusial dalam rekayasa geoteknik, terutama dalam proyek konstruksi yang melibatkan lahan miring. Penelitian ini membahas tahapan stabilitas lereng dengan penggunaan retaining wall, sebuah struktur yang berfungsi untuk mencegah pergeseran tanah dan longsor. Permodelan lereng dilakukan menggunakan perangkat lunak PLAXIS 8.6. Untuk lereng dengan kemiringan 1H:1.5V, menghasilkan faktor keamanan sebesar 1.1760. Untuk meningkatkan stabilitas, dilakukan pemotongan lereng menjadi 1H:1V, yang memberikan faktor keamanan 1.3720, yang dinilai aman hanya untuk kondisi sementara. Selanjutnya, sistem drainase sementara diterapkan sebelum konstruksi retaining wall menggunakan bored pile yang dirancang untuk mencapai lapisan tanah andesit. Setelah dilakukan pemodelan ulang faktor keamanan meningkat menjadi 1.5258, menunjukkan kondisi yang sesuai untuk jangka panjang. Proses diakhiri dengan backfilling dan penerapan sistem drainase permanen. Berdasarkan standar Bowles (1993) dan SNI 8460:2017, faktor keamanan minimum untuk konstruksi adalah 1.25 untuk kondisi minimum dan 1.3 untuk kondisi sementara, serta 1.5 untuk kondisi permanen. Hasil penelitian menunjukkan bahwa penerapan retaining wall dapat meningkatkan stabilitas lereng secara signifikan.
