"O" BANDO E O LOBO” A PARTIR DA CONCEPÇÃO DE HOMO SACER DE GIORGIO AGAMBEN
Authors: DA COSTA SILVA CHERULLI EULICE JAQUELINE 
Published: November 2021

RESUMO
Busca-se, com este estudo, a partir das concepções apontadas por Giorgio Agamben na obra Homo Sacer – o poder soberano e a vida nua (2007), compreender a noção de vida nua e poder soberano e como, a partir dessa relação, é verificada a designação do ‘bando’ e do ‘lobo’, na qual o homem passa a ser constituído por uma vida sem valor, em que, apesar de estar sob a égide de um poder soberano (o Estado), se vê excluído da sociedade pelo mesmo ente que o protege. Com o aporte teórico de grandes filósofos e pensadores, como Arendt, Levi, Hobbes e Heidegger, Agamben (2007), traça um estudo sobre a vida do homem a partir de uma perspectiva política que, ao invés de buscar a proteção (da vida) do indivíduo, tem-se ocupado como ferramenta de segregação e imposição sobre quem se enquadra na esfera matável, pautado no poder soberano.

Gender and age detection assist convolutional neural networks in classification of thorax diseases
Authors: Ali Mumtaz , Ali Riaz 
Published: November 2021

Conventionally, convolutional neural networks (CNNs) have been used to identify and detect thorax diseases on chest x-ray images. To identify thorax diseases, CNNs typically learn two types of information: disease-specific features and generic anatomical features. CNNs focus on disease-specific features while ignoring the rest of the anatomical features during their operation. There is no evidence that generic anatomical features improve or worsen the performance of convolutional neural networks for thorax disease classification in the current research. As a consequence, the relevance of general anatomical features in boosting the performance of CNNs for thorax disease classification is investigated in this study. We employ a dual-stream CNN model to learn anatomical features before training the model for thorax disease classification. The dual-stream technique is used to compel the model to learn structural information because initial layers of CNNs often learn features of edges and boundaries. As a result, a dual-stream model with minimal layers learns structural and anatomical features as a priority. To make the technique more comprehensive, we first train the model to identify gender and age and then classify thorax diseases using the information acquired. Only when the model learns the anatomical features can it detect gender and age. We also use Non-negative Matrix Factorization (NMF) and Contrast Limited Adaptive Histogram Equalization (CLAHE) to pre-process the training data, which suppresses disease-related information while amplifying general anatomical features, allowing the model to acquire anatomical features considerably faster. Finally, the model that was earlier trained for gender and age detection is retrained for thorax disease classification using original data. The proposed technique increases the performance of convolutional neural networks for thorax disease classification, as per experiments on the Chest X-ray14 dataset. We can also see the significant parts of the image that contribute more for gender, age, and a certain thorax disease by visualizing the features. The proposed study achieves two goals: first, it produces novel gender and age identification results on chest X-ray images that may be used in biometrics, forensics, and anthropology, and second, it highlights the importance of general anatomical features in thorax disease classification. In comparison to state-of-the-art results, the proposed work also produces competitive results.

Published: November 2021

The on-going COVID-19 pandemic has highlighted telehealth as a crucial tool in delivering high quality healthcare with increased efficiency. In the Kingdom of Saudi Arabia this has been evidently clear with the establishment of the robust Ministry of Health 937 COVID-19 hotline. The objectives of our study are to describe the clinical patterns of COVID-19, identify the most common concerns of the 937 hotline callers and to identify the associations between the clinical presentation of COVID-19 and risk factors of the patients.through an Analytic Cross-Sectional study design. Results : The average age was 36.8 ± 15.7 years, 61.1% were males and 38.9% were females. 69.3% were Saudi and 30.7% were non-Saudis. 82.5% employed, whilst 17.5% were unemployed.The most commonly reported symptoms were fever, followed by fatigue and cough respectively. With 41.8%, 28.2% and 23.2% of participants reporting those symptoms respectively. The most significant predictors of developing shortness of breath due to COVID-19 was chronic lung disease OR=5.7pvalue >0.01, chronic kidney disease, OR = 4.8 p value >0.02 and immunocompromised state OR = 19 >0.01. 82% of all calls to the hotline were related to COVID-19 testing, and 11% of all calls resulted in the caller receiving medical counselling and/or treatment without having to make a physical visit to a healthcare provider. Conclusion : A well-designed telehealth program can mitigate the need for a physical visit to the emergency room or clinic and as such reduce the load on front-line healthcare workers, reducing transmission and improving outcomes during infectious disease epidemics. It can also provide valuable insights into the presentation and risk factors of a new disease to aid in the prevention, diagnosis, management and control of the disease.

AbstractPurposeTo investigate the effect of different pitches and corresponding scan fields of view (SFOVs) on the image quality in the ultrafast, high‐pitch turbo FLASH mode of the third‐generation dual‐source CT using an anthropomorphic phantom.MethodsThe phantom was scanned using the ultrafast, high‐pitch turbo FLASH protocols of the third‐generation dual‐source CT with the different pitches and corresponding SFOVs (pitches: 1.55 to 3.2 with increments of 0.1, SFOVs: 50 cm to 35.4 cm). The objective parameters such as the CT number, image noises, signal‐to‐noise ratio (SNR), contrast‐to‐noise ratio (CNR), and artifacts index (AI), and image features from the head, chest, and abdomen were compared between the CT images with a pitch of 1.55 and SFOV of Ø 50 cm and a pitch of 3.2 and SFOV of Ø 35.4 cm. Then, the 18 series of CT images of the head, chest, and abdomen were evaluated by three radiologists independently.ResultsThe differences in the CT numbers were not statically significant between the CT images with a pitch of 1.55 and SFOV of Ø 50 cm and a pitch of 3.2 and SFOV of Ø 35.4 cm from most body parts and potential combinations (p > 0.05), Most of the image noises and the AI from the images with the pitch of 1.55 were significantly lower than those with the pitch of 3.2 (p < 0.05), and the SNR and CNR from the images with the pitch of 1.55 were higher than those with the pitch of 3.2. There were significant differences in the first‐order features and texture features of the head (59.3%, 28.3%), chest (66%, 35.7%), and abdomen (71.6%, 64.7%) (p < 0.05). The subjective image quality was excellent when the pitch was less than 2.0 and gradually decreased with the increasing pitch. In addition, the image quality decreased significantly when the pitch was higher than 3.0 (all k≥0.69), especially in the head and chest.ConclusionsIn the ultrafast, high‐pitch turbo FLASH mode of the third‐generation DSCT, increasing the pitch and lowering the corresponding SFOV will change the image features and cause more artifacts degrading the image quality. Specific to the clinical needs, decreasing the pitch not only can expand the SFOV but also can improve the image quality.

Published: November 2021

AbstractCeramic (nano)materials are promising materials for bone regeneration applications. The addition of bioinorganics such as strontium (Sr) and zinc (Zn) is a popular approach to further improve their biological performance. However, control over ion delivery is important to prevent off‐target effects. Mesoporous silica nanoparticles (MSNs) are popular nanomaterials that can be designed to incorporate and controllably deliver multiple ions to steer specific regenerative processes. In this work, MSNs loaded with Sr (MSNSr) and surface coated with a pH‐sensitive calcium phosphate (MSNSr‐CaP) or calcium phosphate zinc layer (MSNSr‐CaZnP) are developed. The ability of the MSNs to promote osteogenesis in human mesenchymal stromal cells (hMSCs) under basic cell culture conditions is explored and compared to ion administration directly to the cell culture media. Here, it is shown that MSN‐CaPs can effectively induce alkaline phosphatase (ALP) levels and osteogenic gene expression in the absence of other osteogenic stimulants, where an improved effect is observed for MSNs surface coated with multiple ions. Moreover, comparatively lower ion doses are needed when using MSNs as delivery vehicles compared to direct ion administration in the medium. In summary, the MSNs developed here represent promising vehicles to deliver (multiple) bioinorganics and promote hMSC osteogenesis in basic conditions.

AbstractInfrared laser systems are vital for applications in spectroscopy, communications, and biomedical devices, where infrared nonlinear optical (NLO) crystals are required for broadband frequency down‐conversion. Such crystals need to have high non‐resonant NLO coefficients, a large bandgap, low absorption coefficient, and phase‐matchability among other competing demands; for example, a larger bandgap leads to smaller NLO coefficients. Here, the successful growth of single crystals of γ ‐NaAsSe2 that exhibit a giant second harmonic generation (SHG) susceptibility of d11 = 590 pm V−1 at 2 µm wavelength is reported; this is ~18 times larger than that of commercial AgGaSe2 while retaining a similar bandgap of ~1.87 eV, making it an outstanding candidate for quasi‐phase‐matched devices utilizing d11. In addition, γ ‐NaAsSe2 is both Type I and Type II phase‐matchable, and has a transparency range up to 16 µm wavelength. Thus, γ ‐NaAsSe2 is a promising bulk NLO crystal for infrared laser applications.
