Clearing Kidney Exchanges via Graph Neural Network Guided Tree Search (Student Abstract)

Kidney exchange is an organized barter market that allows patients with end-stage renal disease to trade willing donors—and thus kidneys—with other patient-donor pairs. The central clearing problem is to find an arrangement of swaps that maximizes the number of transplants. It is known to be NP-hard in almost all cases. Most existing approaches have modeled this problem as a mixed integer program (MIP), using classical branch-and-price-based tree search techniques to optimize. In this paper, we frame the clearing problem as a Maximum Weighted Independent Set (MWIS) problem, and use a Graph Neural Network guided Monte Carlo Tree Search to find a solution. Our initial results show that this approach outperforms baseline (non-optimal but scalable) algorithms. We believe that a learning-based optimization algorithm can improve upon existing approaches to the kidney exchange clearing problem.
Multidimensional Analysis of Trust in News Articles (Student Abstract)

The advancements in the field of Information Communication Technology have engendered revolutionary changes in the journalism industry, not only on the part of the journalists and the media personnel, but also on the people consuming these news stories, who today, are only a click away from all the updates they need. However, these advances have also exposed the prevailing venality, wearying off the trust of the public in news media. How then, does an individual discern that which, out of the countless news stories for an incident, should be trusted? This work introduces a system that presents the user a multidimensional analysis for trust in news from various media sources based on the textual content of the articles, assessment of the journalists' perspectives and the temporal diversity of the issues being covered by the media houses publishing the news articles. Our experiments on a self-collected dataset confirm that the system aids in a comprehensive analysis of trust.
Brucella, a monospecific genus as shown by deoxyribonucleic acid hybridization

A total of 51 strains (including type, reference, vaccine, and field strains) representing all species and biovars of Brucella formed a single deoxyribonucleic acid-deoxyribonucleic acid hybridization group (S1 nuclease method). Accordingly, we propose that only one species, Brucella melitensis, be recognized in the genus. We recommend that other specific epithets formerly associated with the generic name Brucella be used in a vernacular form for biovar designation (e.g., Brucella melitensis biovar Abortus 1).
Cichlid Fish Diversity Threatened by Eutrophication That Curbs Sexual Selection

Cichlid fish species of Lake Victoria can interbreed without loss of fertility but are sexually isolated by mate choice. Mate choice is determined on the basis of coloration, and strong assortative mating can quickly lead to sexual isolation of color morphs. Dull fish coloration, few color morphs, and low species diversity are found in areas that have become turbid as a result of recent eutrophication. By constraining color vision, turbidity interferes with mate choice, relaxes sexual selection, and blocks the mechanism of reproductive isolation. In this way, human activities that increase turbidity destroy both the mechanism of diversification and that which maintains diversity.
Extracellular signals and intracellular pathways in diabetic nephropathy

SUMMARY: The pathogenesis of diabetic nephropathy (DN) includes genetic, haemodynamic and metabolic factors and oxidative stress as well as renal hypertrophy. Among them, hyperglycaemia is necessary, but not sufficient, for the development of DN. The toxicity of hyperglycaemia results from glucose overutilization and multiple secondary effects. Renal cells respond to extracellular signals [high glucose, glycated proteins, mechanical strain, cytokines/growth factors, especially angiotensin II (AII) and transforming growth factor-β (TGF-β)] by way of cell-surface receptors and activating or inhibiting intracellular pathways. These pathways form a complex network with extensive interactions. Intracellular pathways relevant in DN are polyol, protein kinase C (PKC, especially the PKCβ isoform), reactive oxygen species (ROS, associated with many pathways), nitric oxide (NO; through increased expression of endothelial constitutive NO synthase), mitogen-activated protein kinase (MAPK) cascade (extracellular signal-regulated kinase and p38 MAPK may act as glucose transducers), calcium, Janus kinase (JAK)/signal transducers and activators of transcription (STAT), NF-κB (an inflammatory transcription factor), Smads (transcription factors activated by TGF-β superfamily), cell cycle regulatory proteins (retinoblastoma protein phosphorylation; cdc2 kinase; p16INK4, p21Cip1 and p27kip1 cyclin-dependent kinase inhibitors), AP-1 (a heterodimer of Fos and Jun transcription factors) and transcriptional co-activators (e.g. CBP/p300, which binds to NF-κB, STATs, Smads and AP-1, thereby enabling the interactions among these signals). The therapeutic effects of AII inhibition are mediated by haemodynamic and non-haemodynamic factors. In fact, because AII induces TGF-β and many DN-related intracellular pathways (e.g. PKC, ROS, MAPK, JAK/STAT, NF-κB and AP-1), many of the non-haemodynamic effects of AII inhibition may be mediated by inhibiting these pathways. While some extracellular signals (mechanical strain, hyperglycaemia, AII and TGF-β) have fulfilled Koch's postulates, none of the intracellular pathways have. However, many inhibitors of these intracellular pathways are being actively researched. These inhibitors may be useful in future therapy for DN.
Visceral Leishmaniasis in Children

Leishmaniasis is a protozoan parasitic disease. Leishmaniasis is divided into 3 categories, e.g. Visceral Leishmaniasis (VL), Cutaneous Leishmaniasis (CL) and Mucocutaneous Leishmaniasis (MCL). For VL, the estimated number of new cases per year may have decreased to <100,000, but previous estimates ranged up to 400,000 or more cases. Clinically, the Visceral leishmaniasis is characterized by fever (>14 days), loss of weight, anemia and splenomegaly. Children are affected and may die in two years if left untreated. Diagnosis is confirmed by demonstration of the parasite (Leishmania donovani) from bone marrow or splenic aspirate. A number of effective drugs are available to treat the disease including children. Oral drug Miltefosine is highly effective to treat VL in children.
Context and Social Simulation

Context is everywhere in the human social and cognitive spheres but it is often implicit and unnoticed. Some possible reasons for this will be sketched below. However, when one is involved in trying to understand and model the social and cognitive realms it becomes an important factor. This paper is an analysis of the role and effects of context on social simulation and a call for it to be squarely faced by the social simulation community.
GENO - Optimization for Classical Machine Learning Made Fast and Easy

Most problems from classical machine learning can be cast as an optimization problem. We introduce GENO (GENeric Optimization), a framework that lets the user specify a constrained or unconstrained optimization problem in an easy-to-read modeling language. GENO then generates a solver, i.e., Python code, that can solve this class of optimization problems. The generated solver is usually as fast as hand-written, problem-specific, and well-engineered solvers. Often the solvers generated by GENO are faster by a large margin compared to recently developed solvers that are tailored to a specific problem class.An online interface to our framework can be found at http://www.geno-project.org.
Embedding High-Level Knowledge into DQNs to Learn Faster and More Safely

Deep reinforcement learning has been successfully applied in many decision making scenarios. However, the slow training process and difﬁculty in explaining limit its application. In this paper, we attempt to address some of these problems by proposing a framework of Rule-interposing Learning (RIL) that embeds knowledge into deep reinforcement learning. In this framework, the rules dynamically effect the training progress, and accelerate the learning. The embedded knowledge in form of rule not only improves learning efﬁciency, but also prevents unnecessary or disastrous explorations at early stage of training. Moreover, the modularity of the framework makes it straightforward to transfer high-level knowledge among similar tasks.
30. Differential Growth in the Crab Ocypoda

Summary. 1 Measurements were made of the carapace and of the lengths of each segment, of the appendages of thirty-two male Ocypodu aegyptiaca, of carapace lengths ranging from 11–4 to 42.1 mm. 2 The results previously obtained by Huxley for O. ceratophthalma were confirmed as regards the negative heterogony of the walking-legs with respect to the carapace (section 4), the presence of a centre of low growth-potential in the merus of these legs and the complex nature of the growth-gradient in them. The growth-gradient is not a simple inverted form of that found in other crustacea, but contains at least three inflexions (section 5). 3 Both of the chelae are positively heterogonic. The growth-gradients within them are of a similar form to those in the walking-legs. This form of the growth-gradient is therefore not necessarily associated with negative heterogony (section 6). 4 The growth-gradient in the third maxilliped also shows some resemblance the that in the walking-legs, there being a minimum in segments iii. and iv. (section 7). 5 Data for the growth of the eye and eye-stalk are given. These show extreme heterogony (section 8). 6 In many segments of the appendages the growth-rate relative to carapace length was found to change during that part of the total development which was studied. In the walking-legs and in segment iv. of the chelae growth was retarded in the older individuals. In most other segments of the large chela it was accelerated. Growth of the carapace in width relative to its growth in length was also retarded in the later stages. Growth of the walking-legs relative to carapace width was constant throughout the range (sections 4 to 8). 7 There was no indication of an antero-posterior growth-gradient in the appendages (section 9) nor of any influence of the high growth-rate of the large chela on the growth-rate of adjacent appendages (section 10). 8 In all four pairs of walking-legs the two terminal segments on the side of the small chela were, on the average, slightly longer than those on the opposite side of the body. This effect is much smaller in degree and opposite in sign to that found in the related genus Uca. No other evidence of asymmetry (apart from the chelae) could be found. No difference in the lengths of the chelae between right- and left-handed specimens could be established (section 10).
E.COLI CULTURE IN DROPLETS USING FLUIGENT FLUOROSURFACTANT

In vitro cell culture is a fundamental component of biological production systems and biotechnological research. The ability to grow cells outside of their natural environment offers many possibilities ranging from high quantity production of enzymes to cell toxicity studies. Traditionally, in vitro cell culture methods use petri dishes or culture flasks for laboratory cell culture. In culture flasks, cells are grown in a homogenous liquid medium, while petri dishes allow the growth of colonies on a solid or semi-solid substrate surface. Nevertheless, these two methods have limitations including the difficulty to compartmentalize clones and single cells.Compartmentalization allow single cells or clones to be individually assayed or exposed to different culture conditions or stimuli for versatile (or multiparametric) analysis of cells heterogeneity.
Heat-shock protein expression in a perennial grass commonly associate with active geothermal areas in western North America

Heat-shock protein (hsp) expression in response to short(hours) versus long-term (weeks) heat was examined in Dichanthelium lanuginosum. Expression of cytoplasmic class I small hsps (shsps) and hsp 101 was elicited by 2 h above 401C, along with an increase over basal levels of hsp 70. Elevated levels of heat-induced shsp and hsp 101 persisted for 5–7 days after plants were returned to control temperatures. Protein extracts from roots exposed to 421C for several weeks displayed increased levels of shsp but decreased hsp 101 levels. This decrease in hsp 101 did not occur in D. lanuginosum from normothermic environments. r 2002 Elsevier Science Ltd. All rights reserved.
A Review on Face Reenactment Techniques

Existing Face Re-enactment approaches have two major limitations, first, they require large dataset of images to create photo-realistic face models and second, they do not generalize well if the facial images are not available in training dataset. The generation of a new facial reenactment requires large image dataset and hours are required to train these models. Some progress in Deep Learning has shown quite significant results using Generative Adversarial Networks (GANs). Recent works in GAN have solved the problem of large dataset training dataset by introducing the concept of few-shot learning. This paper reviews existing approaches in Face Re-enactment with few-shot learning techniques and other approaches in Face Re-enactment.

Response pattern of Mimosa pudica e Senna obtusifolia to potentially allelopathic activity of Poaceae species

Allelopathy is an important device to measure interferences affecting the dynamics of plant species in agricultural systems. This study aimed to determine the existence of response patterns of the weeds Mimosa pudica and Senna obtusifolia to species of the family Poaceae, through interaction between species and fractions, and arrangement of the effects. Bioassays of seed germination and radicle and hypocotyl elongation were developed under controlled conditions. Hydro-alcoholic extracts at 1.0% of the leaf, root and seed fractions of four species of Poaceae were tested. Differences in intensity of the effects for species and fractions were verified. The activity pattern observed for Paspalum maritimum was the presence of more intense inhibitions. Among Brachiaria species, the most intense inhibitions were produced by B. brizantha. There was an intense effective response for specificity between species and fractions for germination and radicle elongation, especially for Mimosa pudica. Only the P. maritimum extracts showed specificity and were effective in relation to seed germination and radicle elongation of the species Senna obtusifolia. Lleaf fraction was more effective for inhibition, especially for the species P. maritimum. Comparatively, the species Mimosa pudica was more responsive to the effects of the extracts, especially in relation to radicle and hypocotyl development. The intensity of the allelopathic activities varied as follows: radicle elongation > seed germination > hypocotyl elongation. The arrangement of the results for indicators of inhibition showed a pattern discrimination for the receiving species, suggesting specificity of the extracts.
Transient Analysis of Tidal Power Plant Connected to Network When Faced with Symmetrical and Unsymmetrical Faults

Over the last few decades, the growing need for electricity and the environmental pollution concerns have attracted the attentions towards the use of renewable energy more than ever. The tidal energy is a renewable energy which provides clean power with low running costs and is more predictable than other types of renewable energies. A proper integration of tidal power to the power grid is an important and a challenging task. In this paper, the behavior of a tidal power plant connected to the grid when faced with different types of short circuits, the speed behavior and productive, active and reactive power changes are analyzed. The effect of water rip on the stability of tidal power plants is also studied.
Effects of light, CO2 and inhibitors on the current output of biofuel cells containing the photosynthetic organism Synechococcus sp

The current output of the biofuel cells containing a marine alga, Synechococcus sp. and an electron transport mediator, 2-hydroxy-1,4-naphthoquinone (HNQ) was increased under illumination and in the presence of CO 2 . The inhibitory effects of carbonyl cyanide m-chlorophenylhydrazone (CCCP), 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU), 2,5-dibromomethylisopropyl-p-benzoquinone (DBMIB), phenylmercury acetate (PMA) and N,N'-dicyclohexylcarbodiimide (DCCD) on the output current of fuel cells run in the light suggested that HNQ accepts electrons mainly at the site of ferredoxin-NADP + reductase (FNR) in the electron transfer chain.
Web-application Security Evaluation as a Service with Cloud Native Environment Support

This paper describes an approach automating the vulnerability scanning and security testing with the cloud-native solution, which provides a self-contained environment that spins up the scanners and configuration settings in a single click. With the advancement of technology, it's hard to say a web application is 100% secure from vulnerabilities and attacks from the outside world. So it is a must to confirm the security of the applications. If the sensitive data, it holds leaked to the hackers or intruders, it can even harm a whole nation. There are security scanning scanners and standards introduced by the security bodies. Web security testers are consuming a considerable amount of time to do the manual testing on web application security testing because of the configurations and the environments set up is a time-consuming work. This advanced research tool is capable of running a dynamic security scan and do a dependency check as a package to identify the security loopholes without any prior knowledge on security testing. This paper presents test results and evaluation results to prove the proposed concepts.

Optimal Realization of Full Adder in QCA using 5-input majority gate

This work showcases an optimal layout for 5input majority gate, that occupy less QCA area when compare to existing gates. A new QCA layout of Full adder has demonstrated to showcase the applicability. To consider realistic clock distribution, we have utilized USE (Universal, Scalar and Efficient) clocking technique for implementing the Full adder. QCAdesigner based results confirmed that the presented structure has outperformed existing designs taking QCA cells, area occupied and clock delay as design metrics. Proposed design shows 45% drop in cell numbers and requires 78% reduction in area when compare to previous superior design implemented on existing clocking techniques.
Intestinal Microflora of Larval and Juvenile Stages in Japanese Flounder (Paralichthys olivaceus)

Investigations on the aerobic bacterial flora in the intestine of larval and juvenile stages in Japanese flounder (Paralichthys olivaceus) were carried out at two different fisheries stations. The bacterial flora of ambient water and feeds were also analyzed. The number of bacteria in the intestine of larvae measuring 10 mm in total length was 105 CFU/fish, remained nearly constant until 14 mm, and decreased to 104 CFU/fish in 15-19 mm. The decrease in bacterial numbers was hypothesized to be due to the change in feeds from live diets (rotifer and brine shrimp) to artificial diets. The bacterial numbers on ZoBell's 2216e agar were 104, 108, 105, and 106 CFU/ml or g in water, live feeds, artificial feed and minced fish, respectively.The composition of intestinal flora was characterized by two predominating groups of Vibrio and Pseudomonas followed by Moraxella, Cytophaga and Alcaligenes. Similar generic composition was recovered in water and live diets, while those of artificial diets comprised of Acinetobacter and Gram-positive bacteria in addition to Moraxella. Vibrio alginolyticus was frequently isolated from fish examined in one station where no apparent fish mortality occurred.
Guided Dual Networks for Single Image Super-Resolution

The PSNR-oriented super-resolution (SR) methods pursue high reconstruction accuracy, but tend to produce over-smoothed results and lose plenty of high-frequency details. The GAN-based SR methods aim to generate more photo-realistic images, but the hallucinatory details are often accompanied with unsatisfying artifacts and noise. To address these problems, we propose a guided dual super-resolution network (GDSR), which exploits the advantages of both the PSNR-oriented and the GAN-based methods to achieve a good trade-off between reconstruction accuracy and perceptual quality. Specifically, our network contains two branches, where one is trained to extract global information and the other to focus on detail information. In this way, our network simultaneously generates SR images with high accuracy and satisfactory visual quality. To obtain more high-frequency features, we use the global features extracted from the low-frequency branch to guide the training of the high-frequency branch. Besides, our method utilizes a mask network to adaptively recover the final super-resolved image. Extensive experiments on several standard benchmarks show that our proposed method achieves better performance compared with state-of-the-art methods. The source code and the results of our GDSR are available at https://github.com/wenchen4321/GDSR.
On the Design of Reconfigurable Wideband Ridge Gap Waveguide Amplifier Modules

The near-to-launch 5G standard for wireless communications did not seal the ultimate use the mm-wave bands. As a result, the future 6G standard is expected to proceed in more efficient utilization of these bands. One of the most critical elements in the RF link is the amplifier, especially when the attenuation of the channel is relatively high which is the case for the mm-wave bands. In this work, a reconfigurable design of a wideband amplifier is presented to operate in the band 34 GHz to 38 GHz. The line parameters are investigated to study the tune-ability of this configuration. In particular, changing the parasitic loading by varying lines width can achieve a matching level beyond 15 dB over partial band operations based on the configuration. The availability of such a reconfigurable module will pave the way for efficient 6G development.
