Published: November 2021

Background: The aim of this study was to evaluate the application of the rapid influenza antigen test and the contribution of the test result to patient management in febrile infants aged 29‒90 days. Methods: The medical records of febrile infants without a focus who presented during influenza seasons from 2017‒2019 were analyzed retrospectively. The study was carried out in the Department of Pediatric Emergency, Dr. Sami Ulus Maternity and Children’s Training and Research Hospital. The demographic characteristics, clinical and laboratory findings, and management of the patients were examined. The patients were divided into two groups as ‘with’ and ‘without’ testing based on whether a rapid influenza antigen test was performed or not. Test results were categorized as positive or negative. Serious bacterial infection (SBI) risk and patient management were evaluated according to test results. Results: A total of 173 patients (110 males/63 females) were evaluated. The influenza test was performed in 94 (54.3%) patients, and 31.9% were positive. SBI was present in 8.7% of all patients. The mean values of white blood cell (WBC), absolute neutrophil, platelet count, C-reactive protein (CRP) and, lumbar puncture, hospitalization, and initiation of antibiotic therapy were significantly lower in the positive group compared to the negative and without testing groups (P<0.05). Conclusion: This study showed that using the influenza test in the emergency department in young febrile infants significantly reduced the use of antibiotics, hospitalization and the implementation of invasive procedures such as lumbar puncture, and the risk of SBI was not increased.

Background: Comb homolog enhancer 1 (EPC1) gene is one of the important members of epigenetic inhibitor PCG family. It shows carcinogenic potential in a variety of malignant tumors, but the expression and role of EPC1 in nasopharyngeal carcinoma are unclear. The aim of this study was to explore the expression and function of enhancer of polycomb homolog 1 (EPC1) in nasopharyngeal carcinoma (NPC). Methods: The differential expression of EPC1 in the cancer tissues and cell lines of NPC was examined by quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR). EPC1 expression, cell proliferation, and apoptosis were detected in NPC cell lines after EPC1 silencing, and the levels of the epithelial-mesenchymal transition (EMT)-related proteins E-cadherin and vimentin were detected in NPC cells after EPC1 silencing. The study was performed at Fujian Provincial Hospital, Fujian, China, from 2018 to 2019. Results: We found that EPC1 was significantly upregulated in the cancer tissues and cell lines of NPC (P<0.001). Furthermore, knockdown of EPC1 inhibited the growth and metastasis of NPC cells. E-cadherin and vimentin were detected in NPC cells after EPC1 was knocked out. It was confirmed that inhibition of EPC1 resulted in increased E-cadherin expression (P<0.001) and decreased vimentin expression (P<0.001), suggesting that inhibition of EPC1 could inhibit the EMT in NPC cells. Conclusion: EPC1 expression was upregulated in NPC tissues and cell lines. Knockout of EPC1 effectively inhibited the growth of NPC cells, induced apoptosis, and inhibited invasion and metastasis. Inhibition of EPC1 could inhibit the EMT in NPC cells. All of the above findings support the viewpoint that EPC1 plays a pro-cancer role in NPC.

Breast cancer is one of the rarest types of cancer in men. Its incidence increases with age, as in women. Neurofibromatosis type 1 is an autosomal dominant genetic disease that predisposes to many cancer types. Neurofibromatosis and breast cancer have been more frequently distinguished and better studied in women. Characteristically, estrogen, progesterone receptors, negative, and overexpression of human epidermal growth factor receptor 2 (HER2) are detected in patients with female neurofibromatosis breast cancers. In cases reported so far, estrogen and progesterone receptors have been evaluated as positive and HER2 negative in male patients. With the high possibility of breast cancer development in female patients with neurofibromatosis at an earlier age, prompt and careful evaluation is required in terms of both examination and radiological imaging. Unfortunately, there are no thorough recommendations for breast cancer follow-up in male patients with neurofibromatosis. Here, we present a breast cancer, which is an uncommon type of cancer in male neurofibromatosis.

Published: November 2021

Çalışmanın temel hedefleri İzmir ili yerleşiklerinin afetler konusundaki temel bilgi ve bilinç düzeyinin ölçülmesi ve bu veriler ışığında kamu kurum ve kuruluşlarının yapacakları bölgesel afet planlarına sayısal veriler oluşturmaktır. Bu amaç doğrultusunda çalışmada ulusal ve uluslararası alandaki afet tanımları açıklandıktan sonra İzmir ili yerleşikleriyle yapılan anket görüşmesinin sonuçlarına yer verilmiştir. Çalışma nitel araştırma yöntemi olarak kabul edilen yazılı dokümanların incelenmesi ve nicel araştırma yöntemi olan anket metotlarına dayandırılmıştır. Çalışma kapsamında İzmir ilinde yaşayan yerleşiklerin temel afet bilgi ve bilinç düzeyinin düşük olduğu sonucuna ulaşılmıştır. Eğitim düzeyinin azalması, yaşın artması ve gelir seviyesinin düşmesi afet bilgi ve bilinç düzeyini olumsuz bir şekilde etkilerken; afet yaşayan ve yaşamayanlar arasında ise afet bilgi ve bilinç düzeyi konusunda herhangi farklılık bulunamamıştır. İl genelinde yerleşikler arasındaki iletişiminin düşük, ikincil ilişkilerin yaygın olması nedeniyle afet konusundaki dayanışma düzeyinin de istenilen seviyede olmadığı tespit edilmiştir. Ülke genelinde afet eğitim programları ve tatbikatlarının yaygınlaştırılması, afetlerle ilgili kamu spotlarının izlenme oranları en yüksek olduğu saatlerde yayın organları tarafından belli aralıklarla verilmesinin sağlanması, afetler konusundaki bilgiye erişimin kolaylaştırılması gibi yöntemlerle bilgi ve bilinç eksikliğinin giderilebileceği düşünülmektedir.
Comparing example generation with classification in the learning of new mathematics concepts
Authors: Kinnear George
Published: November 2021

Prompting learners to generate examples has been proposed as an effective way of developing understanding of a new concept. However, empirical support for this approach is lacking. This article presents two empirical studies on the use of example-generation tasks in an online course in introductory university mathematics. The first study compares the effectiveness of a task prompting learners to generate examples of increasing and decreasing sequences, with a task inviting them to classify given examples; it also investigates the effectiveness of different sequences of generation and classification tasks. The second study replicates the investigation of interactions between generation and classification tasks. The findings suggest that there is little difference between the two types of task, in terms of students' ability to answer later questions about the concept.

W graficznym projekcie okładki najnowszego numeru Rocznika Filozoficznego Ignatianum przedstawiono bramę wjazdową na zamek królewski na Wawelu, czyniąc z niej łuk triumfalny otwierający się ku drodze, rozpoznawalnej dla każdego człowieka czującego więź z dziedzictwem kulturowym świata Zachodu. Ta zdefiniowana droga to via Appia, zbudowana niegdyś z woli Appiusza Klaudiusza Ślepego, uchodząca za jeden z najstarszych traktów rzymskich. Nazywana przez samych Rzymian „królową dróg”, u człowieka wychowanego na wartościach, jakie niesie ze sobą cywilizacja Zachodu, jest nierozłącznie związana z Wiecznym Miastem. To o nim pisał w sławnym epitafium Mikołaj Sęp-Szarzyński: „dziś w Rzymie zwyciężonym Rzym niezwyciężony”, dając wyraz narzucającej się świadomości łączenia tego, co przeszłe, z tym, czego doświadczamy jako obecne. To na tej drodze rozegrała się legendarna scena przywołana przez Henryka Sienkiewicza, w której pytanie: Quo vadis, Domine? [dokąd zmierzasz, Panie?] zadaje uciekający z Wiecznego Miasta apostoł Piotr spotkanemu na trakcie apijskim Chrystusowi. Siłę tego pytania rozumie każdy, kto w korzeniach klasycznych i chrześcijańskich potrafi dostrzec to wszystko, co dla kultury zachodniej jest najważniejsze nie tylko w przeszłości, ale również w przyszłości.

Such cooperation is due to the need to improve the infrastructure sectors, the efficiency of which affects not only the welfare and quality of life, but also creates the conditions for intensifying investment activities and increasing productivity in the fields of material production. However, modernization of infrastructure is not possible only at the expense of private partners, so it requires financial participation of state or local authorities.

The purpose of the article is to identify the problems of public funding of public-private partnership infrastructure projects in Ukraine and to develop recommendations for their solution, taking into account the best world practices.

Results. The study showed that public funding of public-private partnership projects in Ukraine is carried out through the use of direct and indirect state support. It is established that its forms are insufficiently adapted in domestic practice, as they have a restrictive nature of action, and also contain many gaps in the legislation.

Conclusions. Increasing the investment attractiveness of infrastructure projects implemented on the basis of public-private partnership requires state support. At the same time, state and local authorities should adhere to the provisions: providing state support in the process of implementing strategically important PPP projects in the field of socio-economic activities by legislative regulation of the procedure for determining the level of contribution of a supported investment project; determining the type of financial participation of the state (provision of state guarantees, subsidies or budget investments) should be based on economically justified performance indicators; involvement of state representatives to assess the feasibility of choosing certain forms of state support, forecasting the possible risks to prevent budget imbalances; ensuring transparency of public funding of PPP projects, which will increase the level of confidence in the investment market.

The purpose of this research is to help us understand and examine the process of allocating Cash Direct Assistance from village funds, maps of social conflicts and mitigation efforts against conflicts that occur in Seumadam village, Vocational Muda District. This study uses a qualitative descriptive research method. The results showed that the data collection process, determination, method and mechanism for distributing BLT-DD Kampung Seumadam had been carried out in accordance with existing regulations. Social conflicts caused by the distribution of BLT-Dana Desa Seumadam Village occurred vertically and horizontally. vertical conflicts occur between the Village Government and the community, while horizontal conflicts occur between the Seumadam village community itself. The causes of the conflict occurred, among others, due to the absorption of community aspirations that had not been maximized in the distribution of BLT-Village Funds and the absence of socialization carried out by the village government regarding the process or mechanism for distributing BLT-Village Funds. Mitigation efforts against conflicts that occur are carried out through a process of deliberation and socialization of the assistance program carried out by the village.

We investigated various aspects of the in-orbit performance of SEVIRI on Meteosat-10 (launch: 05 Jul 2012) and -11 (launch: 15 Jul 2015) with images, where Mercury or Venus appeared in a corner. These objects are of similar or smaller size than the instantaneous field of view, and therefore they are well suited for checks of geometric requirements. From comparing the position of Venus in different channels we conclude that the North-South distance between the two focal planes is shorter than the nominal value by 0.66 km at SSP (Sub-Satellite Point) with Meteosat-10 and longer by 1.44 km at SSP with Meteosat-11. The tilt of the detector array against the equator is less than 0.0037° for SEVIRI on Metosat-10. The sampling with narrow channels is 3.0016 km, with a one-sigma uncertainty of 30 cm at sub-satellite point. The tests we carried out to check the geometric performance of the instrument confirmed that SEVIRI is compliant with the requirements. The Point Spread Function as determined from the image of a planet agrees well with the expectations based on its combination with the finite impulse response. Finally we determined the stability of the calibration coefficients from the counts obtained on the planetary targets and found the reproducibility of the measurements of planetary fluxes similar to those of vicarious calibration targets. Hence planets are a promising alternative to established methods of in-flight characterisation and validation of imagers.

This paper presents a suite of algorithms for detecting and localizing attacks in cyber-physical systems, and performing improved resilient state estimation through a pruning algorithm. High performance rates for the underlying detection and localization algorithms are achieved by generating training data that cover large region of the attack space. An unsupervised generative model trained by physics-based discriminators is designed to generate successful false data injection attacks. Then the generated adversarial examples are used to train a multi-class deep neural network which detects and localizes the attacks on measurements. Next, a pruning algorithm is included to improve the precision of localization result and provide performance guarantees for the resulting resilient observer. The performance of the proposed method is validated using the numerical simulation of a water distribution cyber-physical system.
Aerial Intelligent Reflecting Surface Enabled Terahertz Covert Communications in Beyond-5G Internet of Things

Published: November 2021

Unmanned aerial vehicles (UAVs) are envisioned to be extensively employed for assisting wireless communications in the Internet of Things (IoT).

On the other hand, terahertz (THz) enabled intelligent reflecting surface (IRS) is expected to be one of the core enabling technologies for forthcoming beyond-5G wireless communications that promise a broad range of data-demand applications. In this paper, we propose a UAV-mounted IRS (UIRS) communication system over THz bands for confidential data dissemination from an access point (AP) towards multiple ground user equipments (UEs) in IoT networks. Specifically, the AP intends to send data to the scheduled UE, while unscheduled UEs may behave as potential adversaries. To protect information messages from the privacy preservation perspective, we aim to devise an energy-efficient multi-UAV covert communication scheme, where the UIRS is for reliable data transmissions, and an extra UAV is utilized as an aerial cooperative jammer, opportunistically generating artificial noise (AN) to degrade unscheduled UEs detection, leading to communication covertness improvement.

This poses a novel max-min optimization problem in terms of minimum average energy efficiency (mAEE), aiming to improve covert throughput and reduce UAVs' propulsion energy consumption, subject to satisfying some practical constraints such as the covertness requirements for which we obtain analytical expressions. Since the optimization problem is non-convex, we tackle it via the block successive convex approximation (BSCA) approach to iteratively solve a sequence of approximated convex sub-problems, designing the binary user scheduling, AP's power allocation, maximum AN jamming power, IRS beamforming, and both UAVs' trajectory and velocity planning. Finally, we present a low-complex overall algorithm for system performance enhancement with complexity and convergence analysis. Numerical results are provided to verify the analysis and demonstrate significant outperformance of our design over other existing benchmark schemes concerning the mAEE performance.
«Débarquer/démarquer»: Voltaire e Magellano
Authors: Landi Michela
Published: November 2021

Following Voltaire’s Essai sur les mœurs, the first explorers of the new worlds are innocents: they respond to the mythic imagery of the first man. It is on their successors that lays the blame: interested in material enrichment, they despoil the new world. After Magellan, the first geographical demarcation line having been overcome, the culture degeneration of Western world is double: geographic and hermeneutic. Voltaire is in fact not so far from Rousseau’s thinking.
Quattro viaggi nel tempo, rimanendo in città: cronotopi nella narrativa brasiliana contemporanea

If the concept of time-space, associated to the travel, usually refers to a space-temporal changing from a subject, the aim of this work is to reflect on the possibility to use the same concept for a different process, that involves space and time in other positions regarding to the subject, or else the physical immobility and the research during the time. In the last years some famous Brazilian novels deal not only with actual themes, but they find again their present origins in places cancelled by the urban palimpsest: the senzalas and the slavery live again in the echos of very different works as Becos da memória by Conceição Evaristo (2006), Passageiro do fim do dia by Rubens Figueiredo (2010), and O amor dos homens avulsos by Victor Heringer (2016).
