Risk factors associated with Acute Respiratory Infection (ARI) among children under 10-years in Rohingya refugee camp
Authors: Oishi Shafiqua Nawrin , Alam Nazmul
Published: July 2020

Acute respiratory infections are cause by bacterial, fungal or viral infections of the respiratory tract. Very young and older aged people are most vulnerable of these infections lead to difficulties from fever, cough, nasal discharge, sputum production, fatigue, wheezing, pain on swallowing, at times ear infections and meningitis. With huge number of Rohingya influx in Bangladesh, camps are overly crowded allowing many infectious diseases to transmit easily. Although there are researches that have been conducted in this area, there remains a huge gap of research in these camps where children being vulnerable are mostly suffering from respiratory disease such as Acute Respiratory Infection (ARI). This cross-sectional study investigated the risk factors associated with ARI among children less than 10 years in Rohingya refugee camps. After collecting information based on their demographic, anthropometric, history of respiratory problem, accommodation and nutritional status, it was found that about 21.6% of 259 children under this study had symptoms of ARI. Living in congested housing and with lack of nutritious food children were found negatively associated with ARI.

Published: July 2020

Here, we report a reproducible method for the synthesis of SA-Ms on the surface of the electroactive bacterium, Geobacter sulfurreducens (GS). Our approach is based on the extracellular electron transfer capability of GS to reduce extracellular metal ions by harvesting the metabolically formed electrons inside the cell. The formation of SA-Ms on the surface of GS was achieved by creating an MN3 moiety (where M=Ir, Pt, Co, Ru, Cu, and Pd, and N = nitrogen), identified by X-ray absorption fine structure analysis. Interestingly, our bio-derived SA-M@GS can be directly used as OER and HER electrocatalysts upon drying without further heat treatments such as pyrolysis or hydrothermal approaches.
Living Environmental Laboratory for Lighting: Reduction of Light Pollution at Hungarian Settlements
Authors: Száz Dénes , Kolláth Zoltán , Szabó Ferenc , Csuti Péter
Published: July 2020

The International Dark Sky Association has a flight of rules for public lighting in dark sky parks. In Hungary, many settlements still illuminate with compact fluorescent lights and sodium lamps, that do not fulfill these rules. In our research project, financed by a grant of the European Union, we established a system of Living Environmental Laboratory for Lighting at two settlements in dark sky parks in Hungary. As the first step, the public lighting system was reconstructed, so that it satisfied the rules of IDA. We designed new LED luminaires with optimal illumination and optical properties to provide the necessary luminous intensity and reduce light pollution at the same time. The new system has a two-step illumination profile: (i) Early night, after sunset, when the traffic is still high, warm white LEDs are applied to ensure sufficient lighting coming to the roads and pavements with a wide beam of light. (ii) Late night, when the traffic is low, the illumination switches to amber LEDs that have a narrower light beam to minimize light pollution and provide sufficient visibility. This approach can be an optimal illumination construction to reduce the light pollution of public lighting at night.

El café es uno de los cultivos más relevantes en México, su importancia radica en que es un cultivo sustentable, ha sido adoptado y adaptado por comunidades indígenas y genera divisas para el país. Una de las regiones caficultoras más importantes del país, es la del Pacífico Sur, compuesta por Chiapas, Oaxaca y Guerrero donde se produce 53% del café y se encuentra 60% de los productores de este aromático. La presencia de las plagas y enfermedades en el café puede generar pérdidas entre 30 al 50% de la producción. La broca de café Hypothenemus hampei (Ferrari) es el problema entomológico mas grave de este cultivo y su presencia en el país es de hace más de 40 años, actualmente se encuentra en todos los estados que cultivan café. Es por ello, que en este trabajo se generó una metodología práctica que calculó espacialmente los grados días de desarrollo de la broca de café a través de la temperatura de la superficie registrada por imágenes Modis con una resolución espacial de 1 km y con una resolución temporal de un día, monitoreando del 01 de abril de 2018 al 31 de marzo de 2019. Los resultados indicaron que en esta región se puede formar hasta 13 generaciones de la plaga, presentando riesgo en casi todo el año, tanto por el desarrollo como en la dispersión de la plaga. Esta metodología puede apoyar a fortalecer el monitoreo que se hace de la plaga en el país.

Published: July 2020

BackgroundThere has been widespread concern that so-called ‘lockdown’ measures, including social distancing and school closures, could negatively impact children’s mental health. However, there has been little direct evidence of this impact due to the paucity of longitudinal studies reporting mental health before and during lockdown. This present study provides the first longitudinal examination of changes in childhood mental health, a key component of an urgently needed evidence base that can inform policy and practice surrounding the continuing response to the COVID-19 pandemic. MethodsMental health assessments on 168 children (aged 7.5-11.6 years) were taken before and during the UK lockdown. Assessments included self-reports, parent-reports, and teacher-reports. Mean mental health scores before and during the UK lockdown were compared using mixed linear models. FindingsA significant increase in depression symptoms during the UK lockdown was observed, as measured by the RCADS short form. Confidence intervals suggest a medium-to-large effect size. There were no significant changes in RCADS anxiety subscale and SDQ emotional problems subscale.InterpretationDuring the UK lockdown children’s depression symptoms have increased substantially, relative to before lockdown. The scale of this effect has direct relevance for the continuation of different elements of lockdown policy, such as complete or partial school closures. This early evidence for the direct impact of lockdown must now be combined with larger-scale epidemiological studies that establish which children are most at risk, and tracks their future recovery.FundingThis study was supported by grant TWCF0159 from the Templeton World Charity Foundation to DEA, and by the UK Medical Research Council.

Older adults show a more sustained pattern of effortful listening than young adults
Authors: McGarrigle Ronan , Knight Sarah , Rakusen Lyndon , Geller Jason , Mattys Sven
Published: July 2020

Listening to speech in adverse conditions can be challenging and effortful, especially for older adults. This study examined age-related differences in effortful listening by recording changes in the task-evoked pupil response (TEPR; a physiological marker of listening effort) both at the level of sentence processing and over the entire course of a listening task. A total of 65 (32 young adults; 33 older adults) participants performed a speech recognition task in the presence of a competing talker, while moment-to-moment changes in pupil size were continuously monitored. Participants were also administered the Vanderbilt Fatigue Scale; a questionnaire assessing daily life listening fatigue within four domains (social, cognitive, emotional, physical). Normalized TEPRs were overall larger and more steeply rising and falling around the peak in the older versus the young adult group during sentence processing. Additionally, mean TEPRs over the course of the listening task were more stable in the older versus the young adult group, consistent with a more sustained recruitment of compensatory attentional resources to maintain task performance. No age-related differences were found in terms of total daily life listening fatigue; however, older adults reported higher scores than young adults within the social domain. Overall, this study provides evidence for qualitatively distinct patterns of physiological arousal between young and older adults consistent with age-related upregulation in resource allocation during listening. A more detailed understanding of age-related changes in the subjective and physiological mechanisms that underlie effortful listening will ultimately help to address complex communication needs in aging listeners.
Extended Imagining: the case of the aphantasic artist
Authors: MacKisack Matthew , Zeman Adam , Winlove Crawford , Onians John , Macpherson Fiona , Aldworth Susan
Published: July 2020

Can visual imagining ever be other than a brain-bound, organismically internal process? The practices of artists with aphantasia - the congenital or acquired incapacity to generate visual mental imagery - suggests that it can. Here we report on a qualitative study of ‘aphantasic’ artists and find that imagery lack coincides with a dependence on external, environmental, structures to generate artwork. Indeed, physical manipulations of external media seem to take place in lieu of the ability to generate and manipulate internal, mental images. Cognitive functions that could, for the non-aphantasic, be carried out by mental imagery - such as bringing non-conscious visio-spatial relationships to awareness - can only be carried out for the aphantasic by manipulating their environment. Thus aphantasic art-making constitutes extended visual imagining. As such, it undermines the universality of the ‘hylomorphic’ model of art-making, in which the work is mentally preconceived before being realised in the material world, with the fact of neurocognitive diversity.
Perceptual vs. automated judgments of music copyright infringement

Published: July 2020

Music copyright lawsuits often result in multimillion dollar damage awards or settlements, yet there are few objective guidelines for applying copyright law in infringement claims involving musical works. Recent re-search has attempted to develop objective methods based on automated similarity algorithms, but there remains almost no data on the role of perceived similarity in mu-sic copyright decisions despite its crucial role in copy-right law. We collected perceptual data from 20 participants for 17 adjudicated copyright cases from the USA and Japan after editing the disputed sections to contain either full audio, melody only, or lyrics only. Due to the historical emphasis in legal opinions on melody as the key criterion for deciding infringement, we predicted that listening to melody-only versions would result in perceptual judgements that more closely matched actual past legal decisions. Surprisingly, however, we found no significant differences between the three conditions, with participants matching past decisions in between 50-60% of cases in all three conditions. Automated algorithms designed to calculate melodic and audio similarity produced comparable results: both algorithms were able to match past decisions with identical accuracy of 71% (12/17 cases). Analysis of cases that were difficult to classify suggests that melody, lyrics, and other factors sometimes interact in complex ways difficult to capture using quantitative metrics. We propose directions for further investigation of the role of similarity in music copy-right law using larger and more diverse samples of cases and enhanced methods, and adapting our perceptual experiment method to avoid relying for ground truth data only on court decisions (which may be subject to selection bias). Our results contribute to important practical debates, such as whether jury members should be allowed to listen to full audio recordings during copyright cases.
LDL-AURIS: A computational model, grounded in error-driven learning, for the comprehension of single spoken words
Authors: Shafaei-Bajestan Elnaz , Moradipour-Tari Masoumeh , Uhrig Peter , Baayen R. H.
Published: July 2020

A computational model for auditory word recognition is presented that enhances the model of Arnold et al. (2017). Real-valued features are extracted from the speech signal instead of discrete features. One-hot encoding for words’ meanings is replaced by real-valued semantic vectors, adding a small amount of noise to safeguard discriminability. Instead of learning with Rescorla-Wagner updating, we use multivariate multiple regression, which captures discrimination learning at the limit of experience. These new design features substantially improve prediction accuracy for words extracted from spontaneous conversations. They also provide enhanced temporal granularity, enabling the modeling of cohort-like effects. Clustering with t-SNE shows that the acoustic form space captures phone-like similarities and differences. Thus, wide learning with high-dimensional vectors and no hidden layers, and no abstract mediating phone-like representations is not only possible but achieves excellent performance that approximates the lower bound of human accuracy on the challenging task of isolated word recognition.
Debates on Social Exclusion and Inclusion in Nepal
Authors: Ghimire Dipesh
Published: July 2020

The term “Social Exclusion” is used to describe a wide range of phenomena and processes related not only to poverty and deprivation, but also to social, cultural and political disadvantages, and in relation to a wide range of categories of excluded people. However, there is no single way of understanding the concepts of social exclusion and inclusion. In the context of Nepal, power was consolidated by interlinking it with the Hindu caste system. The social order was exclusionary because it classified all groups as distinct castes within the broad framework of the Hindu system of the four varnas based on concepts of ritual purity and pollution. This paper has attempted to present a quick and preliminary discussion on theoretical perspectives on social exclusion and inclusion. The paper has also emphasized on the major debates on social exclusion and inclusion in Nepal and thematic aspects of social exclusion and inclusion.
Fatou, Julia, and escaping sets of conjugate holomorphic semigroups
Authors: Subedi Bishnu Hari , Singh Ajaya
Published: July 2020

We define commutator of a holomorphic semigroup, and on the basis of this concept, we define conjugate semigroups of a holomorphic semigroup. We prove that the conjugate semigroup is nearly abelian if and only if the given holomorphic semigroup is nearly abelian. We also prove that image of each of Fatou, Julia, and escaping sets of a holomorphic semigroup under commutator (affine complex conjugating map) is equal respectively, to the Fatou, Julia, and escaping sets of the conjugate semigroup. Finally, we prove that every element of a nearly abelian holomorphic semigroup S can be written as the composition of an element from the set generated by the set of commutators !(S) and the composition of the certain powers of its generators..
Clinical variety of affective, sleep and motor manifestations in craniocervical dystonia (a literature review)
Authors: Khaiatova Z. G. , Zalyalova Z. A.
Published: July 2020

Recent research data literature indicates the presence of non-motor symptoms in patients with dystonia such as mood disorders, cognitive impairments, sleep disturbances, autonomic dysfunction and / or pain, which are important components of quality of life. The article discusses possible comorbidity of affective manifestations,sleep disorders and dystonia. Currently, evidence is controversial, and the question requires further study. Affective symptoms and sleep disturbances of dystonia are now recognized as the greater determinant of quality of life in dystonia, being associated with health and disability, although their contribution to the clinical picture of the disease often remains underestimated. It becomes important to identify these manifestations, assess their severity and impact on the daily activity of patients with craniocervical dystonia.

Negotiating Identities
Authors: Cann Victoria
Published: July 2020

In this article I explore the nuanced performances of masculinity enacted by a 14-year-old boy named “Tom.” Tom, a boy of Filipino descent, complicated much of what was the case with other (non-Filipino) young male participants in my study when it came to masculinity. Rather than simply (re) producing hegemonic masculinity, I show in this article how Tom played with his masculinity and countered potential accusations of homosexuality through acts of self-exoticization and self-feminization (removing others’ power to do so). I explore the role that Tom’s Filipino heritage and London background plays in his performance of masculinity, arguing that in the overwhelmingly white context of Norfolk (UK), it serves to anchor his hegemonic masculinity through connotations of “toughness” and “urbanness.” It is therefore in Tom’s emphasis of his diasporic “Otherness” that his gender transgressions can be consolidated.
James Joyce’s “The Sisters”
Authors: Ryan Barry
Published: July 2020

The topic of pederasty in “The Sisters” has attracted extensive commentary. In this discussion, the boy’s confusion, growing up at the crux of two views of masculinity, has not been explored. Moreover, Father Flynn’s nostalgic view of boyhood, and his dependency on the company of the boy, also warrants exploration. Furthermore, little has been made of the boy’s antagonistic relationship with Father Flynn’s sisters, as there is evidence in the story that the boy is considered corruptive. It is my contention that pederasty is not the larger issue, as in another context, this could be contested. Rather, the boundary between the boy and adults is constructed across two opposing ideals of masculinity, obliterating any possibility of contestation. Subsequently, sentient and reflexive aspects of the boy’s characterization deviate from how children are viewed by adult characters in Dubliners.
A high-definition 3D exoscope as an alternative to the operating microscope in spinal microsurgery
Authors: Siller Sebastian , Zoellner Caroline , Fuetsch Manuel , Trabold Raimund , Tonn Joerg-Christian , Zausinger Stefan
Published: July 2020

OBJECTIVE

Since the 1970s, the operating microscope (OM) has been a standard for visualization and illumination of the surgical field in spinal microsurgery. However, due to its limitations (e.g., size, costliness, and the limited movability of the binocular lenses, in addition to discomfort experienced by surgeons due to the posture required), there are efforts to replace the OM with exoscopic video telescopes. The authors evaluated the feasibility of a new 3D exoscope as an alternative to the OM in spine surgeries.

METHODS

Patients with degenerative pathologies scheduled for single-level lumbar or cervical spinal surgery with use of a high-definition 3D exoscope were enrolled in a prospective cohort study between January 2019 and September 2019. Age-, sex-, body mass index–, and procedure-matched patients surgically treated with the assistance of the OM served as the control group. Operative baseline and postoperative outcome parameters were assessed. Periprocedural handling, visualization, and illumination by the exoscope, as well as surgeons’ comfort level in terms of posture, were scored using a questionnaire.

RESULTS

A 3D exoscope was used in 40 patients undergoing lumbar posterior decompression (LPD) and 20 patients undergoing anterior cervical discectomy and fusion (ACDF); an equal number of controls in whom an OM was used were studied. Compared with controls, there were no significant differences for mean operative time (ACDF: 132 vs 116 minutes; LPD: 112 vs 113 minutes) and blood loss (ACDF: 97 vs 93 ml; LPD: 109 vs 55 ml) as well as postoperative improvement of symptoms (ACDF/Neck Disability Index: p = 0.43; LPD/Oswestry Disability Index: p = 0.76). No intraoperative complications occurred in either group. According to the attending surgeon, the intraoperative handling of instruments was rated to be comparable to that of the OM, while the comfort level of the surgeon’s posture intraoperatively (especially during “undercutting” procedures) was rated as superior. In cases of ACDF procedures and long approaches, depth perception, image quality, and illumination were rated as inferior when compared with the OM. By contrast, for operating room nursing staff participating in 3D exoscope procedures, the visualization of intraoperative process flow and surgical situs was rated to be superior to the OM, especially for ACDF procedures.

CONCLUSIONS

A 3D exoscope seems to be a safe alternative for common spinal procedures with the unique advantage of excellent comfort for the surgical team, but the drawback is the still slightly inferior visualization/illumination quality compared with the OM.

Shards of broken glass
Authors: Beronja Vlad
Published: July 2020

This article
examines Daša Drndić's April in Berlin
(April u Berlinu, 2007), alongside
the author’s other Holocaust novels, as literary responses to historical
revisionism and outright denialism of the Holocaust in Croatia, which had
emerged into the political and cultural mainstream during the War of
Independence (1991-1995) and has persisted into the post-war period. Since the
historical legacy of the Fascist NDH in Croatia has been de-traumatized, it no
longer represents a crisis of historical consciousness, which would entail a
confrontation with the violent past as well as a painful transformation of
national identity and the political space in which this identity is
articulated. In contrast to de-traumatization, as an ethnocentric strategy that
normalizes the nation’s fascist crimes, Drndić’s novels stage a shocking
confrontation with the shards of the violent past. Through both their
innovative graphic layout and interdiscursive textuality—which combines
historiographical narration with avant-garde fictional and artistic devices,
words with image—Drndić’s novels function as literary archives and monuments,
and archives as monuments, intended
to disturb, disrupt, and jolt the reader into awareness of traumatic history, laying
bare the ideological mechanisms of political control and bringing the bodies of
victims to our doorstep.
IL-17 predicts the effect of TACE combined with apatinib in hepatocellular carcinoma
Authors: Wu Yongjuan , Cheng Guangyuan , Chen Hui , Wang Jingzhong , Wang Jiangtao , Wang Wanbi
Published: July 2020

OBJECTIVE: IL-17 is considered to be a cancer-promoting gene in hepatocellular carcinoma (HCC). Here, we explored the effect of IL-17 in predicting the therapeutic effect of transcatheter arterial chemoembolization (TACE) combined with apartinib in patients with HCC in this study. METHODS: Established of IL-17 knockdown SK-Hep1 cells for studying the effects of IL-17 expression on the invasion and migration of human HCC cells in vitro by transwell assay and tumor angiogenesis in nude mouse. Immunohistochemistry was used to detect the expression of IL-17, E-cadherin, Vimentin and CD34 protein in 175 cases of human HCC tumor tissues. Kaplan-Meier was used to analyze the prognostic significance of TACE combined with apatinib treatment in HCC patients. RESULTS: n SK-Hep1 cells, IL-17 knockdown could increase E-cadherin protein expression, reduce vimentin protein expression, inhibit cell invasion and migration in vitro, and inhibit angiogenesis of tumor and decrease plasma VEGF level in nude mouse. In tumor tissues of HCC patients, IL-17 protein expression was negatively correlated with E-cadherin protein expression (r = –0.622, P < 0.001), positively correlated with Vimentin protein expression (r = 0.540, P < 0.001), and was positively correlated with MVD of HCC tumor tissues (r = 0.564, P < 0.001). Compared with adjuvant TACE alone, patients with low-expression of IL-17 treated combined with apatinib have a higher 5-year overall survival. However, additional apatinib treatment did not significantly improve 5-year overall survival in HCC patients with high IL-17 expression. CONCLUSION: IL-17 had a pivotal role in the invasion and angiogenesis of HCC and contribute to the selection of patients who may benefit from adjuvant TACE combined with apatinib.

Feature extraction is the basis of texture analysis. How to obtain texture features with small feature dimension, simple calculation and comprehensive representation of images is a hot spot and a difficult point in feature extraction. The traditional image texture feature extraction method is to process the image in the spatial domain. However, due to its high computational complexity, its practical application is restricted. Based on this, this study studies the extraction method of texture features, and deeply analyzes the principle of non-subsampled Contourlet transform. Moreover, this study uses NSCT to transform the image from the spatial domain to the frequency domain and extracts the texture features of the decomposed low frequency sub-band, intermediate frequency sub-band and high frequency sub-band image respectively. In addition, this study selects the appropriate parameters to establish the support vector machine model and applies the extracted texture features into the support vector machine for recognition and applies it to the sports feature recognition. Finally, this study designed a controlled experiment to analyze the performance of the algorithm. The results show that the proposed method has certain effects.

English speech recognition system is affected by a variety of interference factors. Associating the algorithm with the support of modern computer technology can increase the model effect of speech recognition system. Based on the study of the current mainstream controlled natural language thesaurus, this paper proposes a controlled natural language vocabulary classification type. Moreover, this paper defines the domain thesaurus according to the WordNet knowledge description framework, and uses WordNet’s synonym, antisense, upper and lower, etc. In this way, the controlled natural language system can use the semantic relationship of WordNet to identify the words of the non-domain thesaurus input by the user and map the non-domain definition words to the words in the domain thesaurus, thereby improving the ease of use of controlled natural language systems. In addition, this paper designed a controlled experiment to analyze the performance of this system. The research results show that the model constructed in this paper has certain significant effects.

To overcome the disadvantages of low optimization accuracy and prematurity of the canonical PSO algorithm, we proposed an improved particle swarm optimization based on the interaction mechanism between leaders and individuals (PSO-IBLI), and used it to implement robot global path planning. In the PSO-IBLI algorithm, in different stages, each particle learns from the elites according to different regular. Moreover, the improved algorithm divides the execution state into two categories, where the parameters and the evaluation mechanisms are varied accordingly. In this way, the global best particles no longer walk randomly and have more learning objects. At the same time, other particles learn from not only the global best position, their historical best positions, but also the other elites. The learning strategy makes the search mode always in the adaptive adjustment, and it improves the speed of convergence and promotes this algorithm to find a more precise solution. The experimental results suggest that the precision and convergence speed of the PSO-IBLI algorithm is higher than the other three different algorithms. Additionally, some experiments are carried out to plan the robot’s entire collision-free path using the PSO-IBLI algorithm and the other three algorithms. The results show that the PSO-IBLI algorithm can obtain the shortest collision-free way in four algorithms.

Data outsourcing has gradually become a mainstream solution, but once data is outsourced, data owners will without the control of the data hardware, there is a possibility that the integrity of the data will be destroyed objectively. Many current studies have achieved low network overhead cloud data set verification by designing algorithmic structures (e.g., hashing, Merkel verification trees); however, cloud service providers may not recognize the incompleteness of cloud data to avoid liability or business factors fact. There is a need to build a secure, reliable, non-tamperable, and non-forgeable verification system for accountability. Blockchain is a chain-like data structure constructed by using data signatures, timestamps, hash functions, and proof-of-work mechanisms.

Published: July 2020

The more and more developed network has caused more and more impact on people’s life and work, providing convenient channels for people’s information exchange, and then improving people’s living and working conditions. However, when data is transmitted through the network, there are hidden security risks, especially important accounting data. Once intercepted and used by criminals, it may cause serious harm to the owner of the data. Based on the above background, the purpose of this article is to study the use of the DES algorithm to encrypt accounting data in a computing environment. This paper proposes an improved quantum genetic algorithm and applies it to the S-box design of the DES algorithm, which improves the non-linearity of the S-box, reduces the differential uniformity, and enhances the security of the DES algorithm. This improved DES algorithm reduces the number of iterations by increasing the key length and iterative processing using a two-round function, which further increases the security of the algorithm and improves the operation speed of the encryption process. It is found that the 64 ciphertexts of the DES algorithm and the number of changed bits compared to the original ciphertext fluctuates around 32 bits, which explains the problems that should be paid attention to when using the DES algorithm to encrypt accounting data. The validity of key characters should be guaranteed to prevent key loss or leakage. Shorter data encryption regular solution.
