O ato teórico no filme Entre nós talvez estejam multidões: conceito, proposição, programa, série
Authors: Leites Bruno , Macedo Lennon
Published: June 2024

This text proposes an analysis of the movie Entre nós talvez estejam multidões (2020), through the Filmmakers Theory. After presenting the premises of the approach, the article considers four thought production strategies in the film: a) the introduction of the concept of multitude in the title and its dialogue with the images; b) the enunciation of a proposition in the title; c) the existence of a program that structures the film (the “Structuring Autonomous Blocks”); d) the production of a series with the film Videomemória (2020). In this article, each thought production strategy observed is defined in a triangulation that involves interviews from the filmmakers, images and sounds from the film, and concepts arising from the theory of cinema and art.

The book Annoying Music in Everydaylife, by Felipe Trotta, was published in 2020 by Bloomsbury Academic (New York) forming the collection Alternate Takes: Critical Responses to Popular Music. The reflections resulting from several interviews carried out, for the most part, in Rio de Janeiro and Edinburgh (Scotland) point out theoretical and methodological paths for research engaged in similar problems and issues. In this way, such paths can serve as clues for future investigations involving different social contexts and realities.
Interfaces Tangíveis e a Inteligência Artificial: Explorando a Interação Humano-Máquina
Authors: Hildebrand Hermes Renato , Bruscato Portella Grazielle
Published: June 2024

This investigation proposes to observe tangible interfaces (TUIs) through Artificial Intelligence (AI) platforms that, today, play an essential role in the interaction between humans and machines. These are digital means of generating information, communication and interaction that develop together with AIs. These interfaces act as a connection point between users and the media, sending and receiving data and information that enable the visualization of the results generated by the AI algorithms. Taking into account the aesthetics of interaction, the characteristics of the tangible interfaces that constitute AIs will be analyzed and, when contemplating issues such as speculative, responsive and adaptive design and ubiquitous interactions, they adapt to users' preferences and needs.
Inteligência Artificial e Transparência no Jornalismo
Authors: Canavilhas João , Biolchi Bárbara
Published: June 2024

The crisis that has affected journalism since the beginning of the century has led to the dismissal of thousands of journalists worldwide. To address the lack of human resources, many newspapers have turned to artificial intelligence (AI), but the introduction of non-human and poorly scrutinized systems has raised new questions related to the transparency of the journalistic process, affecting the already fragile credibility of the media. In the absence of legislation related to the use of AI in journalism, the media have been publishing recommendations to guide professionals. In this work, we analyze two pioneering documents, one from Estadão (Brazil) and another from the BBC (UK), which show how these media seek to gain consumer trust by explaining how they use artificial intelligence in newsrooms.
Rumo a uma teoria popular de algoritmos
Authors: Siles Ignacio , Gómez-Cruz Edagar , Ricaurte Paola
Published: June 2024

his paper establishes dialogs between theories on the popular and critical studies on algorithms and datafication. In doing so, it contributes to reversing the analytical tendency to assume that algorithms have universal effects and that conclusions about “algorithmic power” in the Global North apply unproblematically every-where else. We begin by clarifying how Latin American scholars and other research traditions have theorized the popular (“lo popular”). We then develop four dimensions of lo popular to implement these ideas in the case of algorithms: playful cultural practices, imagination, resistance, and “in-betweenness.” We argue that this dialogue can generate different ways of thinking about the problems inherent to algorithmic mediation by drawing attention to the remixes of cultural practices, imaginative solutions to everyday problems, “cyborg” forms of resistance, and ambiguous forms of agency that are central to the operations of algorithmic assemblages nowadays.
SinoAsian Futures between Economic Forecasting, Science Fiction, Sinofuturism and Creativity
Authors:   Beijing Normal University-Hong Kong Baptist University-United International College, Briel Holger
Published: June 2024

For many years futurology and forecasting have been a growing field and it seems that this trend is continuing. This article will therefore discuss forecasting, but will claim that it is in need of an important corrective: a kind of self-reflective Science Fiction (hereafter: SF) and the specific critical creativity associated with it. This approach is especially yielding when looking at the case of China. If for the longest time, Science Fiction has been thought of as a western genre, the following suggests that with new movements such as Asian Futurism, Sinofuturism, Afrofuturism or Gulf Futurism, one can observe a new multilateralism taking hold when it comes to the projection and description of possible futures. The Sinofuturism movement will here function as a case study, as it is well suited to point to the innovative power of non-traditional SF. Already one of its forerunners, 1980s Cyberpunk introduced a changing power differential between the east (Japan at the time) and the west, retiring older orientalist and colonial dreams of dominating Asia. This article suggests that this changing power differential can be updated and re-read via the rise of Sinofuturism, its visions and its politics and that it has already become an important socio-political phenomenon to study with which to study cultural Asian-western interactions for times to come.
The Representation of the Anthropocene in Contemporary Chinese Science Fiction
Authors:   Xi’an Jiaotong-Liverpool University, China, ZHOU Yue
Published: June 2024

Contemporary Chinese science fiction (SF) is preoccupied with the representation of the Anthropocene. Wu Ming-yi’s The Man with the Compound Eyes (2011) and Hui Hu’s The Azure Tragedy (2018) are stand-out examples. In light of the framework of ecocriticism, it is found that both writers challenge long-seated anthropocentric thinking and practices in their catastrophic narration of human-induced plastic pollution in the marine environment, increased extinction of species by human overharvesting, and the human-induced general destruction of nature. Both connect natural disasters to human causes and reflect on human supremacy. The futuristic imaginations enabled by the SF genre effectively unfold the slow violence humanity commits and remains oblivious to. However, the criticism offered by the two authors is compromised to some extent. Hui Hu is optimistic about the new technology in dealing with anthropogenic eco-problems, while this technological triumph appears to sidestep the possibility of finding a more sustainable and once-and-for-all solution. Wu Ming-yi implies a new ethical perspective that rejects human centrality and reestablishes the human-nature relationship. On the other hand, he overlooks intra-human inequality in causing and forcing people to experience the eco-catastrophes. This article contributes to a new understanding of contemporary Chinese Anthropocene SF from an ecocritical perspective.
SO MANY FUTURES - aesthetic experience and the now in a performance with and by young people
Authors: Laura Navndrup Black
Published: June 2024

This article provides insight into the choreographic situation LUFTIG, where the idea of air as conveyor of tactile experience is passed on, reworked and performed by children and adults. It examines how shifting the focus from movement language to a distinct expressive idea affects the choreographic process, and looks at how involving young people as choreographers and choreographic material affects the aesthetic experience of the now for artists and audience.

Drawing on Tygstrup's idea of transformative time (2018), Gumbrecht's concept of the broad present (2018) and Taussig's thoughts on the adult's imagination of the child's imagination (2003), the author argues that in performance work where children are both choreographers and choreographic material, the adult’s imagination of the child’s imagination and the actual actions of the physically present child are at the same time mutually dependent on and at odds with each other, leaving the adult teetering on the edge of contemporary reality and primordial retreat.

In the work proces, the child has a special propensity for easing the work for all which can only be deployed if we are able to circumvent tendencies of mutual projection of imagined imaginations. This requires a singular work process, where we - children and adults alike - can inhabit questions together without relying wholly on our previous knowledge of and experience with known performance parameters.

Full-color-tunable Chiral Aggregation-induced Emission Fluorophores with Tailored Propeller Chirality and their Circularly Polarized Luminescence
Authors: Li Yifan , Liang Junhao , Fu Shiwei , Huang Haoxin , Liu Sheng , Wang Lei , Liu Yi
Published: June 2024

The regulation of emission color, emission efficiency and asymmetry
factor is of great significance for the real applications of circularly
polarized luminescent (CPL) materials. Herein, we develop a modular
synthetic strategy toward full-color-tunable CPL materials based on
chiral macrocyclic aggregation-induced emission (AIE) luminogens via
delicate molecular engineering. Modular synthesis of chiral AIEgens with
different acceptor moieties has afforded series of bright solid emitters
with tunable emission colors. These chiral cyclic AIEgens have retained
high solid state emission quantum yield and displayed CPL emission from
blue to red as nano-aggregates, in liquid crystal matrix and polymer
film. The strong acceptor units in the red-emitting chiral AIEgens
RBTPE-2CN and SBTPE-2CN have rendered them twisted
intramolecular charge transfer property and solvatochromic luminescence.
And polymer matrix with different polarity further facilitates the
tuning of CPL emission color from green to red emission. These results
have paved a reliable approach toward constructing full-spectra
solid-state CPL material.
Research on gradual planning scheme of power grid based on AHP and Entropy Weight Method
Authors: zhang yu , zhang qingsheng , li zhen
Published: June 2024

The fusion of renewable energy into power grid planning poses
significant challenges. In this investigation, we assess planning
strategies across eight key indicators encompassing economic,
reliability, environmental, and adaptability considerations. Leveraging
the Analytical Hierarchy Process (AHP) alongside the Entropy Weight
Method, we ascertain both subjective and objective weights, subsequently
synthesizing comprehensive weights with parsimonious discriminative
data. Scores for planning strategies are then derived utilizing these
weights. To illustrate and validate the efficacy of the proposed
methodology, we apply it to four schemes within the IEEE-6 node system,
incorporating wind and photovoltaic power plants.
Robust Beamforming Design for Co-existing Radar and Communication System with Bounded Error Model
Authors: Deng Qijun , jiang zhengming , Huang Min , Zhong Senming , Li Qiang , Zheng Zhenxing
Published: June 2024

The achievement of optimum performance of a co-existing radar and
communication (CRC) system is a challenging task when the channel state
information (CSI) for the interference channels is imperfect,
particularly when the power of the CRC system is restricted. To address
this issue, this article proposes a robust CRC system design that
considers CSI uncertainty. Specifically, the objective is to design a
robust beamforming scheme to maximize the radar performance subject to
the user signal-to-interference-plus-noise ratio （SINR）and the
transmit power of the CRC system. Due to the infinite number of
constraints that result from the CSI uncertainty of the interference
channels, a loosely bound robust approach is developed, which employs
the shrinkage method to convert the infinite number of constraints into
a finite number of constraints. However, the performance of the loosely
bound robust approach is not satisfactory. Therefore, this paper further
proposes a sub-optimal robust approach that employs the S-procedure to
transform the infinite number of inequality constraints into equivalent
finite linear matrix inequalities (LMIs). The simulation results
indicate that the design of the robust CRC system can significantly
improve the system performance compared to the traditional design
approach.
Revisiting Coronene Doped Polymers: Ultra-long and Visible Light Excited RTP in Air
Authors: Liu Guanyu , Chen Junwu , Zhang Shiguo , Zhang Yuefa , Xue Shanfeng , Sun Qikun , Yang Wenjun
Published: June 2024

Coronene (Cor) doped PMMA has been reported to show ultra-long RTP
afterglow under oxygen isolation and UV light excitation, and Cor/PS was
thought to be ineffective doping system. In the current work, we revisit
Cor/PMMA and Cor/PS and find they can emit bright and ultra-long RTP in
air with lifetimes up to 4.431 and 2.968 s after 20 s and 4 min of 365
nm photo-activation, respectively. Further, it is found that both
Cor/PMMA and Cor/PS exhibit rare up to 500 nm light excitable RTP, and
these naked-eye visible afterglows have the lifetimes up to 2.460 and
2.110 s under 440 nm light excitation, respectively. However, Cor has
neither spin-orbital coupling (SOC) values nor visible light absorption
band in polymer films, moreover, Cor/PS is a full hydrocarbon doping
system. Therefore, Cor’s inter-system crossing, triplet state
population, and phosphorescence radiation are not explained via common
SOC promotion mechanism. Based on large planar p system, visible light
excited afterglow, and electron spin resonance and RTP excitation
spectra, we propose that the multiple resonance (MR) effect promotes
triplet population, and the spin-forbidden S →T
population has be enhanced to the extent that visible
light excited RTP afterglow is observed. This work updates the
understanding on RTP properties of Cor/polymers and will intrigue ones
to design RTP dopants with MR promotion and S →T
population for developing novel afterglow polymers.
A novel enlarging fractional bandwidth technique for AWLR-based bandpass filters
Authors: Tang Xianli , Jia Yonghao
Published: June 2024

A novel enlarging fractional bandwidth (FBW) technique for
acoustic-wave-lumped-element resonator (AWLR) -based bandpass filters is
present. The new technique is based on a series of matching inductors
that replace the parallel or series acoustic wave (AW) resonators of AW
filters to beak the bandwidth constraint of the ladder-type structure.
In addition, the transmission response analysis of the proposed
AWLR-based filter is provided. A prototype of the AWLR-based filter is
fabricated and tested to validate the proposed FBW widening technique.
The measured insertion loss, FBW, and out-of-band rejection are 1.5dB,
1.63kt2 (kt2 is the electromechanical coupling coefficient of the AWR),
and 38dB, respectively.
Granulocyte Colony Stimulating factor as Primary prophylaxis to reduce acute mortality during Induction chemotherapy in childhood B cell Non-Hodgkin Lymphoma: report from Tertiary cancer care hospital
Authors: Jameel Madiha , Wali Rabia Muhammad , Zaidi Syed Muhammad Jawad , Ishaq Irfana , Shaheen Najma
Published: June 2024

Background Non-Hodgkin Lymphoma (NHL) accounts for 5% of
childhood cancers in children. Pediatric NHL patients achieve complete
remission in high-income countries; however, mortality is high in low
and middle-income countries due to complicated febrile neutropenia. Data
published from our centre showed acute mortality of 19.7% and sepsis as
the most common cause of death. Use of Granulocyte Colony Stimulating
Factor (G-CSF) has shown to reduce the duration and severity of
neutropenia and decrease the incidence of febrile neutropenia (FN).
Therefore, our study aims to assess a reduction in acute mortality with
the use of GCSF as primary prophylaxis in B-cell NHL and a reduction in
hospital admission days with febrile neutropenia and delays in
subsequent chemotherapy cycle. Methods This is a retrospective
cohort study, performed at Shaukat Khanum Memorial Cancer Hospital and
Research Centre (SKMCH) Lahore. All patients with diagnosis of B Cell
NHL under 10 years of age from January 2018 to October 2021 were
included. Data was collected on patient age, stage of disease, treatment
regimen, day of start of GCSF, number of episodes of FN, duration of
admission in hospital due to FN, day of count recovery and outcomes.
Results Of the 106 patients, 45 (42.4%) were females and 61
(57.5%) were males and 60 patients (56.7%) were between 1-5 years of
age. All patients were started on GCSF on 7 day of
COPADM regimen. Second cycle of induction chemotherapy was given on time
at 21 day in 57 (53.8%). 97 patients (91.5%)
remained alive until end of induction and nine patients expired with
mortality rate of (8.5%). Multi-drug resistant gram negative/positive
bacteremia (32%) and invasive fungal infections (8.5%) remain the most
frequent causes of prolonged febrile neutropenia in these patients. A
total of 48 (45.4%) patients were discharged on 7
day after 1 cycle, 41 (38.6%) remained admitted
for 8-15 days due to prolonged febrile neutropenia, and remaining 17
(16%) of patients remained admitted for more than 15 days due to
prolonged FN. Conclusions Primary prophylactic use of GCSF in
our patients helped reduce mortality to 8.5%, decreases number of FN
episodes, decreases length of hospital stay, and improves count
recovery. Therefore, the use needs to be promoted in pediatric cancer
care centers especially in resource limited settings so that better
outcomes can be achieved.
Mating system variation and gene expression in the male reproductive tract of Peromyscus mice
Authors: Voss Erin , Nachman Michael
Published: June 2024

Genes involved in reproduction often evolve rapidly due to
postcopulatory sexual selection (PCSS) driven by male-male competition
and male-female sexual conflict, but the impact of PCSS on gene
expression has been under-explored. Further, though multiple tissues
contribute to male reproductive success, most studies have focused on
the testes. To explore the influence of mating system variation on gene
expression in the Peromyscus male reproductive tract, we generated
RNAseq libraries and quantified gene expression in the testis, seminal
vesicle, epididymis, and liver of wild-caught monogamous P. californicus
and polygynandrous P. boylii and P. maniculatus males and tested for
positive and relaxed selection on Peromyscus-expressed genes using
published rodent genomes. We identified 3,627 mating-system associated
differentially expressed genes (MS-DEGs), where expression shifted in
the same direction in P. maniculatus and P. boylii relative to P.
californicus. Gene expression variation was most strongly associated
with mating behavior in the seminal vesicles, where 89% of
differentially expressed genes were MS-DEGs, including two key seminal
fluid proteins, Svs2 and Pate4. Though but most genes showing evidence
of positive selection or differential expression did not overlap, 203
MS-DEGs showed evidence of positive selection. Additionally, fourteen
reproductive genes were under tree-wide positive selection but showed
evidence of convergent relaxed selection in P. californicus and Microtus
ochrogaster, a distantly related monogamous species. Changes in
transcript abundance and gene sequence evolution in association with
mating behavior suggest that male mice may respond to variation in
sexual selection by altering aspects of sperm motility, sperm-egg
binding, and copulatory plug formation.

Authors: Benchimol Lionel , Bricmont Noemie , Bonhiver Romane , Hans Grégory A. , Lefebvre Philippe , Kempeneers Céline , Poirrier Anne-Lise
Published: June 2024

Summary: This prospective study investigates the impact of local
anesthesia on ciliary function in nasal epithelium. The primary
objective was to assess whether lidocaine 2% and naphazoline 0.5%
nasal spray alter ciliary beat frequency and pattern in subjects
undergoing nasal brushing, aiming to enhance primary ciliary dyskinesia
(PCD) diagnosis. Hypothesis: It was hypothesized that local anesthesia
administration would not significantly affect ciliary function in nasal
epithelium. Study design: A prospective, simple-blind randomized study
was conducted between 2020 and 2023. The study employed digital
high-speed videomicroscopy to analyze ciliary beat frequency and
pattern. Patient/subject selection: A cohort of 38 participants was
recruited, consisting of 25 healthy volunteers and 13 referred
individuals (including 7 diagnosed with PCD). Selection criteria ensured
absence of chronic respiratory diseases, recent respiratory tract
infections, or regular use of nasal medications. Methodology:
Participants underwent nasal brushing with administration of lidocaine
and naphazoline nasal spray in one nostril and saline in the
contralateral nostril. Ciliary beat frequency and pattern were measured
using digital high-speed videomicroscopy. Results: Nasal spray
administration did not significantly alter ciliary beat frequency or
pattern compared to saline (p = 0.841 and p = 0.125, respectively).
Subgroup analysis revealed consistent results across healthy volunteers,
referred patients, and PCD patients. Conclusion: Local anesthesia with
lidocaine and naphazoline spray did not affect ciliary function
outcomes. These findings support the safe use of these agents in
clinical practice for PCD diagnostic procedures. Further research with
larger cohorts is warranted for validation.
The Prevalence Of Xerostomia In A Group Of Turkish Patients Using An Online Survey During COVID-19 Pandemic
Authors: Yeğinoğlu Sevilay , Ereş Gülden
Published: June 2024

Objectives: Xerostomia is defined as the subjective feeling of
dry mouth. It is a condition that affects millions of patients
worldwide. The aim was to study prevalence and severity of self-reported
xerostomia by sociodemographic variables and to evaluate self-reported
halitosis, burning mouth, and mouth sores. Methods: A
questionnaire regarding sociodemographic data and the 11-item Xerostomia
Inventory was delivered to patients, 20-65 years of age applied to the
XXXX University Faculty of Dentistry for dental treatment before the
COVID-19 pandemic. Statistical analyses were performed to determine the
relationships between the presence of xerostomia and other variables
such as age, gender, the presence of a systemic disease, medication use,
smoking, alcohol consumption, and the use of removable prostheses.
Results: A total of 300 patients were included in the study; a
prevalence of xerostomia of 54.6% was identified. A significant
relationship was found between age and xerostomia ( p = 0.023;
p = 0.001). The prevalence of xerostomia decreased as age
increased. Xerostomia was more common in female patients ( p =
0.028; p = 0.004). The prevalence of xerostomia was found to be
high, not only in the elderly, but also in younger adults.
Conclusion: Xerostomia was reported in approximately one in two
patients in an adult Turkish population. Factors associated with
xerostomia were age, female gender and the number of cigarettes smoked
per day. In this study, the high prevalence of xerostomia was due to
smoking.
Domain-general cognitive control processes in bilingual switching: evidence from midfrontal theta oscillations
Authors: Cui Ningjing , Piai Vitória , Zheng Xiaochen
Published: June 2024

Language control in bilingual speakers is thought to be implicated in
effectively switching between languages, inhibiting the non-intended
language, and continuously monitoring what to say and what has been
said. It has been a matter of controversy concerning whether language
control operates in a comparable manner to cognitive control processes
in non-linguistic domains (domain-general) or if it is exclusive to
language processing (domain-specific). As midfrontal theta oscillations
have been considered as an index of cognitive control, examining whether
a midfrontal theta effect is evident in tasks requiring bilingual
control could bring new insights to the ongoing debate. To this end, we
reanalysed the EEG data from two previous bilingual production studies
where Dutch-English bilinguals named pictures based on colour cues.
Specifically, we focused on three fundamental control processes in
bilingual production: switching between languages, inhibition of the
nontarget language, and monitoring of speech errors. Theta power
increase was observed in switch trials compared to repeat trials, with a
midfrontal scalp distribution. However, this midfrontal theta effect was
absent in switch trials following a short sequence of same-language
trials compared to a long sequence, suggesting a missing modulation of
inhibitory control. Similarly, increased midfrontal theta power was
observed when participants failed to switch to the intended language
compared to correct responses. Altogether, these findings tentatively
support the involvement of domain-general cognitive control mechanisms
in bilingual switching.

focused on Metropolitan Area Networks (MAN). Our tool is capable of
estimating average latency and delay percentiles between every pair of
nodes with minimal computational effort, with the ultimate goal to see
if the MAN is capable of supporting emerging services and applications
that have strict latency requirements. We show that probability bounds
like Vysochanskij–Petunin’s inequality can be used to quickly estimate
latency bounds with minimal computational effort. Theoretical results
are validated with extensive simulations leveraging the simmer package,
an open-source Discrete Event Simulator (DES) written in R, along with
igraph for visualization of networks and shortest path calculations. The
code is publicly available as open-source, and published in Github for
the research community to use and build upon.
Numerical simulation of thermal evolution and grain morphology of laser melted AlSiTiNiCo-WC composite coatings
Authors: Lu Jiazhan , Li Chonggui , Xiong Huaitao , Xia Long , Li Maoliang , Hu Chengwei
Published: June 2024

Simulation of the geometry and internal grain size changes of laser cladding has been extensively studied, with the majority of such simulations focusing on pure metal powders. However, there are fewer simulations for aluminum-based composite coatings by laser cladding. In this paper, a new three-dimensional model of laser cladding composite coatings is proposed, which can accurately determine the geometrical size of the AlSiTiNiCo-WC cladding layer and the internal grain morphology and grain size changes of the cladding layer. The temperature-selective judgment mechanism and material thermal property calculation ensure the calculation accuracy of the composite coating, while the model accurately and intuitively determines the state changes of the composite coating in the process of laser cladding. Furthermore, the model verifies the feasibility of the exponential decay laser source in the simulation of composite cladding, and temperature field analysis accurately predicts the trends of grain morphology and grain size inside the cladding. The simulation results show that the variation of the laser scanning speed has a more pronounced effect on the depth of the cladding layer. The high-temperature gradient at the top of the molten pool is more likely to form fine grains, and the bottom of the cladding layer tends to form coarse columnar crystals with the increase in the internal temperature gradient at the depth. The simulation results were compared with experimental results to validate the accuracy of the simulation process.

Published: June 2024

The development of gastronomic drinks from local cultures is an interesting potential, especially in terms of traditional drinks such as Balinese Arak. However, the sustainability of alcoholic beverage products such as Arak Bali can be affected by various factors, including temperature and storage time. This study aims to investigate the effect of temperature and storage time period on alcohol content in Balinese Arak infused with pineapple. This study used the Quasi Experimental method with a Complete Randomized Design (RAL) design of 2 factors, namely temperature factors and storage time factors. The results of the analysis showed that the Methanol content in the Bali Arak sample had negative results. In samples stored at 1ºC–8ºC for 7, 14, 21, and 28 days, the Ethanol content ranged from 16.38% to 17.27%. Meanwhile, samples stored at temperatures of 24ºC–30ºC during the same period had Ethanol content ranging from 17.27% to 20.49%. The results of statistical analysis using Two Way Anova show that there is a significant influence of temperature and storage time on alcohol content in Balinese Arak infused with pineapple. The results of this study provide further understanding of the factors that influence the stability and characteristics of traditional drinks such as Balinese Arak, and can be a guide in the development of sustainable and quality alcoholic beverage products.
