Az Örnekle Öğrenme Problemleri için MAML ve ProtoNet Algoritmalarının İncelenmesi

Deep neural networks have proven to be very effective for image-related problems. However, their success is mainly attributed to the large-scale annotated datasets that have been used to train them. Convolutional neural networks which are special type of neural networks have achieved very good results for visual recognition problems and therefore have become the standard tool for these tasks. The use of large-scale annotated datasets like the ImageNet have even improved the results obtained by these networks. However, creating an annotated dataset of that scale is very difficult due to its cost. In some cases, even if there are enough resources, it is sometimes impossible to obtain such large datasets. It is shown that the neural networks cannot be trained well if there is not enough training data. As these networks require large amounts of annotated data to be able to generalize well, it is very important to develop new models that can be trained well even if the training data is not abundant. Meta-learning paradigm addresses this problem of few-shot learning by proposing models that can utilize the experience from the previous tasks to learn new tasks. Meta-learning algorithms gain the fast adaptation ability by using the meta-data obtained from the previous tasks. The meta-learning concept has regained its popularity after the success of some deep neural networks-based meta-learning algorithms for the few-shot image classification problems. In this study, two meta-learning algorithms, namely, Model-Agnostic Meta-Learning (MAML) and Prototypical Networks (ProtoNet) are applied to few-shot learning problems and their performance is evaluated. MiniImageNet and CIFAR100 few-shot learning image classification datasets have been used as the test bed, and the two algorithms have been evaluated under different meta-learning and algorithm hyper-parameter settings. The results suggest that MAML results in better classification accuracy than ProtoNet when the number of shot is taken as 1, and ProtoNet results in better accuracy when the number of shot is increased. The main reason for this is that while MAML tries to find common initial weights that can easily distinguish all classes, ProtoNet tries to find a different prototype for each class, and the number of shots definitely increases the representation power of that prototype.
Functions of polyphenols and its anticancer properties in biomedical research: a narrative review

Cancer is a major health concern as the incidence is growing worldwide and still lacks successful therapies. Plant-derived functional foods are getting considerable attention, primarily due to their safety and therapeutic potential. Polyphenols are a group of mostly natural, water-soluble organic compounds. Here, we review the functions of selected polyphenols and their anticancer properties on numerous cancer cell lines and their mechanisms. The literature search was performed using the electronic database PubMed, Google scholar up to June 2020, with the following keywords—polyphenol, polyphenol anticancer, quercetin anticancer, resveratrol anticancer, curcumin anticancer, and kaempferol anticancer. Chemical structures of the selected polyphenols were obtained using the ChemDraw program. The initial search identified 40,554 polyphenols papers and among that, 2,559 were limited to polyphenol and cancer, 987 quercetin and cancer, 2,174 curcumin and cancer, 1,079 resveratrol and cancer, and 226 were limited to kaempferol and cancer. A total of 84 papers are included in this review paper. Most studies report the multiple anticarcinogenic properties of plant-derived polyphenols, including its inhibitory effects on the proliferation of cancer cells, tumor expansion, angiogenesis, inflammation, and metastasis. Besides, some studies shows potential synergistic effects when polyphenol treatment combined with chemotherapeutic agents. Anticancer effects of polyphenolic compounds like quercetin, curcumin, resveratrol, and kaempferol are investigated on numerous cancer cell lines and have shown prominent results. The present review provides a direction to determine the anticarcinogenic ability of the selected polyphenols in vitro and in vivo. Consequently, the use of polyphenols in cancer treatment should be investigated in-depth in the future.

Flexible foams of graphene entrapped SnO2–Co3O4 nanocubes with remarkably large and fast lithium storage

In developing flexible lithium-ion batteries (LIBs), fabrication of a high-performance electrode with good flexibility and stability is desirable, yet remains challenging. Herein, a flexible integrated electrode is introduced based on layer-by-layer packed graphene sheets entrapped SnO2–Co3O4 nanocubes. The rationally selected composition, polyhedral nanostructures, and proper construction of the specific architecture successfully trigger a synergistic lithium storage effect, assuring the partial reversible conversion of SnO2 and interfacial lithium storage of graphene, which are responsible for the remarkably high reversible capacity of 1665 mA h g−1 after 100 cycles at 100 mA g−1. Large and stable cyclic performance as well as long cyclic life is also obtained at a high current density of 1 A g−1 (1208 mA h g−1 after 1000 cycles). More importantly, the free-standing electrode can well retain its flexible feature even after 300 repeated electrochemical cycles, making it a promising candidate for a high-performance and stable electrode for flexible LIBs.
Synthesis of multi-walled carbon nanotube/silica nanoparticle/polystyrene microsphere/polyaniline based hybrids for EMI shielding application

ABSTRACT Novel polystyrene microsphere (PSMS)-based PSMS/Si and polystyrene/silica nanoparticle/multi-walled carbon nanotube (PS/Si/MWCNT) nanocomposite has been prepared using in situ sol-gel and chemical amalgamation methods. Aniline monomer was introduced by in situ route to form PSMS/PANI, PSMS/PANI/Si and PSMS/PANI/Si/MWCNT nanocomposite. FESEM of nanocomposite indicated core-shell spherical and tubular morphology. Glass transition temperature (Tg) and maximum decomposition temperature (Tmax) of PSMS/PANI/Si/MWCNT nanocomposite were found as 295°C and 524°C, respectively, which were higher than the PSMS/PANI (Tg = 245°C; Tmax = 387°C) and PSMS/PANI/Si (Tg = 257°C; Tmax = 388°C) nanocomposite. For nanocomposite dispersion, tetrahydrofuran was studied as fine solvent. XRD depicted amorphous nature of PSMS/Si and PSMS/PANI/Si; however MWCNT reduced amorphous character of PSMS/PANI/Si/MWCNT. Electromagnetic interference (EMI) shielding effectiveness improved from 0.1 dB (PSMS) to 12.3 dB (PSMS/PANI/Si) to 24.5 dB (PSMS/PANI/Si/MWCNT). The increase in EMI shielding effectiveness was also observed with variation in log of conductivity from −14 mho m−1 (PSMA) to 1.17 mho m−1 (PSMS/PANI/Si/MWCNT). GRAPHICAL ABSTRACT
Randomized, Double-Blind, Four-Arm Pilot Study on the Effects of BRAND'­­­­­­S Chicken Essence and FlexC-II® on Joint, Bone, and Muscle Functions

BackgroundKnee osteoarthritis (OA) is a leading cause of disability among elderly individuals. Medical and surgical treatments are expensive and have side eﬀects. The current study aimed to investigate the efficacy and safety of FlexC-II®, a type II collagen hydrolysate, and BRAND'S Essence of Chicken with FlexC-II® (BEC-FlexC-II®) on joint, muscle, and bone functions among elderly adults with OA.MethodsPatients (n = 160) with grade 1–3 knee OA based on the Kellgren–Lawrence classification system, joint pain for ≥3 months, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score of >6 were considered eligible in this study. The participants were randomized into four groups (BEC-FlexC-II®, FlexC-II®, glucosamine hydrochloride [HCl], and placebo) and were instructed to perform resistance training for 24 weeks. The outcomes included WOMAC score, visual analogue scale (VAS) score, hand grip strength, fat-free mass (FFM), bone mass, and 36-Item Short-form Survey score. ResultsThe WOMAC scores of all groups improved after 24 weeks. However, the results did not significantly differ. Meanwhile, there was a remarkable difference in the VAS score between groups (P = 0.039). The FlexC-II® group had a greater reduction in pain than the placebo group (mean ± standard error: −1.3 ± 0.45, P = 0.021). In the FlexC-II® group, the VAS score significantly reduced by 0.9 ± 1.89 (P = 0.034) after 14 days. In the adjusted analyses, the BEC-FlexC-II® group had a significantly higher FFM than the glucosamine HCl (P = 0.02) and placebo (P = 0.017) groups and hand grip strength than the glucosamine HCl group (P = 0.002). Further, on the basis of a subgroup analysis, participants with poor training compliance in the BEC-FlexC-II® group had a significantly higher left hip bone mass than those in the placebo (P = 0.01) and glucosamine HCl (P = 0.049) groups.ConclusionsFlexC-II® relieves OA-associated pain within 14 days, and BEC-FlexC-II® increases muscle mass and strength after 24 weeks. Thus, BEC-Flex-CII® is a promising novel, holistic supplement that can improve mobility by promoting joint, muscle, and bone functions among elderly individuals. However, full-scale studies should be conducted in the future to validate these findings.Trial registrationThis clinical trial was retrospectively registered in ClinicalTrials.gov with the ID NCT04483024 on July 20, 2020.

Gerenciamento eficiente da produção de energia elétrica: desafios para redução do corte de geração de energia das fontes renováveis

O aumento da responsabilidade ambiental tem conduzido a ações sustentáveis mundialmente, inclusive no Brasil. Neste sentido, há uma tendência no aumento de fontes renováveis na geração de eletricidade, com o intuito de descarbonizar a matriz elétrica. Um dos desafios está na crescente participação de fontes intermitentes na matriz elétrica, representadas pela geração eólica e solar. Estas fontes apresentam previsibilidade limitada na geração de energia ao longo do tempo, dependendo de condições meteorológicas locais. A energia renovável gerada pode ter que ser reduzida para manter o equilíbrio entre carga e geração. Deste modo, uma prática comum adotada globalmente é o corte na geração de energia renovável. Esta ação é chamada de curtailment. Este artigo abordará este tema, analisando seus motivos e expondo algumas soluções propostas na literatura. No Brasil, o corte na geração de eletricidade é mais frequente em hidrelétricas. Entre os desafios para a redução deste corte, estão o investimento na expansão da rede de transmissão, o gerenciamento eficiente do despacho de energia e sistemas de armazenamento. Portanto, com o aumento da capacidade instalada em usinas eólica e solar, estudar e analisar estratégias a fim de reduzir o curtailment mostram-se extremamente relevantes, de forma que haja um maior aproveitamento da energia gerada através de fontes renováveis, contribuindo com a segurança da rede.
Carbonization Durability of Two Generations of Recycled Coarse Aggregate Concrete with Effect of Chloride Ion Corrosion

Carbonation durability is an important subject for recycled coarse aggregate concrete (RAC) applied to structural concrete. Extensive studies were carried out on the carbonation resistance of RAC under general environmental conditions, but limited researches investigated carbonation resistance when exposed to chloride ion corrosion, which is an essential aspect for reinforced concrete materials to be adopted in real-world applications. This paper presents a study on the carbonation durability of two generations of 100% RAC with the effect of chloride ion corrosion. The quality evolution of recycled concrete coarse aggregate (RCA) with the increasing recycling cycles was analyzed, and carbonation depth, compressive strength and the porosity of RAC were measured before and after chloride ion corrosion. The results show that the effect of chloride ion corrosion negatively affected the carbonation resistance of RAC, and the negative effect was more severe with the increasing recycling cycles of RCA. Chloride ion corrosion led to a decrease in compressive strength, while an increase in carbonation depth and the porosity of RAC. The equation of concrete total porosity and carbonation depth was established, which could effectively judge the deterioration of carbonation resistance of RAC.
Mass and energetic yields of hydrochar from brewer's spent grain.

Brewer’s spent grain (BSG) was hydrothermally carbonized at combinations of three temperatures (180 °C, 215 °C, 250 °C) and three reaction times (2 h, 5 h, 12 h). For comparison, the corresponding barley malt was also tested at the same conditions. Elemental composition, volatile matter, ash and heating values were determined for original biomasses as well as resulting hydrochars. The mass yield of dry BSG hydrochar ranged from 45 to 73%. The energetic yield defined as retention of total lower heating value in the hydrochar on dry basis ranged from 66 to 85%. Specific lower heating value of dry material rose from 20.6 MJ kg to 30.3 MJ kg at the most severe conditions. Nitrogen and sulphur content in hydrochar were not strongly dependent on reaction conditions.
Finite‐time H2/H∞ control for linear Itô stochastic Markovian jump systems: mode‐dependent approach

This study focuses on the finite-time (FT) H 2 / H ∞ control problem for linear Ito-type stochastic Markovian jump systems (SMJS). According to the characteristics of SMJS, a mode-dependent approach (MDA) is provided. Through MDA, state feedback and observer-based FT H 2 / H ∞ controllers are designed. Compared with the mode-independent approach, the advantages of MDA are clearly shown. In the sequel, two new optimisation algorithms for deriving the optimal FT H 2 / H ∞ controller are proposed. Finally, a numerical example is utilised to show the merits of the obtained results.
THE IMPORTANCE OF PUBLIC TRUST IN GOVERNMENT POLICIES IN EFFORTS TO ACCELERATE THE MANAGEMENT OF THE COVID 19 PLAGUE

Corona Virus Disease 2019 (Covid-19) is a pandemic that is being felt by almost all countries, including Indonesia. Apart from having an impact on the safety of people's lives, it also has an impact on the political and economy aspects. There have been many efforts and policies taken by the central and regional governments to date, but it is still felt that they have not given the public hope when this pandemic will end soon. This has the potential to harm public trust (Trust Public) in the performance of the government to handling the covid-19 outbreak. The purpose of this paper is to describe the alternatives that the government should try to do to increase public trust. Keyword: Covid-19, Government Policy, Trust A. PRELIMINARY Corona Viruses are a large family of viruses that cause disease in both humans and animals. In humans, this virus can usually cause infectious diseases of the respiratory tract, from the common cold to serious illnesses such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). A new type of Corona Virus that was discovered in humans since the outbreak occurred in Wuhan China, in December 2019, was later named Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-COV2), and causes a disease known as Corona Virus Disease-2019 (COVID-19) COVID-19 is caused by SARS-COV2 which belongs to the same large family of Corona Viruses that caused SARS in 2003, only with a different type of virus. Symptoms are similar to SARS, but the SARS death rate (9.6%) is higher than COVID-19 (less than 5%), even though the number of COVID-19 cases is far more than SARS. COVID-19
The radiant emissivity of some materials at high temperatures: review

Experimental data on the emissivity of materials used in high temperature applications have been compiled from a variety of sources. The data are cast in the form of temperature-dependent correlation equations, which can be used for modelling purposes. The data on refractory materials show the importance of surface properties and ways in which this can be taken into account for more accurate predictions of emissivity. Information is also given on a number of surface coatings.
High-order compact difference method for two-dimension elliptic and parabolic equations with mixed derivatives

In this article, firstly, based on Taylor series expansion and truncation error correction technology, combined with the fourth-order Pade schemes of the first-order derivatives, a new fourth-order compact difference (CD) scheme is constructed to solve the two-dimensional (2D) linear elliptic equation a mixed derivative. In this new scheme, unknown function and its first-order derivatives are regarded as the unknown variables in calculation. Then, the method is extended to solve the 2D parabolic equation with a mixed derivative. To match the spatial fourth-order accuracy, The backward differentiation formula (BDF) is employed to gain the fourth-order accuracy for the temporal discretization. Truncation error is analyzed to display that the present scheme is fourth-order accuracy in space. In order to solve the resulting large-scale linear equations, a multigrid method is employed to accelerate the convergence speed of the conventional relaxation methods. Finally, numerical results indicate that the present schemes obtain fourth-order convergence and are more accurate than those in the literature.
“FACE MASK CAN MASK PAIN TOO”- ALEXITHYMIA AND ITS IMPLICATIONS FOR PHYSIOTHERAPISTS DURING THE COVID-19 PANDEMIC

Pain is an unavoidable strand of joint mobilization when dealing with a stiff joint. During this pandemic, patients who undergo this procedure using face mask, risk masking their facial expressions too. Facial grimaces are the ones that a physiotherapist looks out for when gliding a sore joint to get an input on the force they need to apply to the joint. This observational research was carried out on sixteen patients with upper limb pain and stiffness due to varied reasons. The pain endured during mobilization of painful/stiff joints was measured using the Visual Analogue Scale (VAS). The score was calculated without mask on five consecutive days, and then with mask for another five days. Comparison of the mean VAS scores was done using the Independent sample test. The study showed that the patients experienced more pain during joint mobilization when they were masked. There was an average difference of 15 mm between the mean VAS scoring conditions (p<0.05). Therefore, it was concluded that when patients were wearing face masks, there was a greater sense of pain during joint mobilization than without a mask.
The Impact of OFDI on the Technical Complexity of High-tech Industry Export in Home Country

This paper calculates the technical complexity of high-tech industry export in 38 countries from 1997 to 2017, discusses the mechanism of OFDI on the technical complexity of high-tech industry export in the home country, and empirically tests the impact of OFDI on the technical complexity of high-tech industry export in the home country by using the System GMM method of dynamic panel data model. The results show that OFDI can improve the technical complexity of high-tech industry export in the home country. After further analysis, it is found that OFDI can only significantly improve the technical complexity of high-tech industry exports from developing countries, but to a certain extent inhibit the developed countries. In addition, FDI, R & D investment, human capital, openness to the outside world and self owned technology can promote the export technology complexity of a country’s high-tech industry, while the impact of capital endowment on the export technology complexity of developed and developing countries’ high-tech industry is different.
