The ParkourBot - a dynamic BowLeg climbing robot

The ParkourBot is an efficient and dynamic climbing robot. The robot comprises two springy legs connected to a body. Leg angle and spring tension are independently controlled. The robot climbs between two parallel walls by leaping from one wall to the other. During flight, the robot stores elastic energy in its springy legs and automatically releases the energy to “kick off” the wall during touch down. This paper elaborates on the mechanical design of the ParkourBot. We use a simple SLIP model to simulate the ParkourBot motion and stability. Finally, we detail experimental results, from open-loop climbing motions to closed-loop stabilization of climbing height in a planar, reduced gravity environment.

Addressing the flaws of current critical alarms: a fuzzy constraint satisfaction approach

OBJECTIVES
Threshold alarms, the support supplied by commercial monitoring devices to supervise the signs that pathologies produce over physiological variables, generate a large amount of false positives, owing to the high number of artifacts in monitoring signals, and they are not capable of satisfactorily representing and identifying all monitoring criteria used by healthcare staff. The lack of an adequate support for monitoring the evolution of physical variables prevents the suitable exploitation of the information obtained when monitoring critical patients. This work proposes a solution for designing intelligent alarms capable of addressing the flaws and limitations of threshold alarms.


MATERIALS AND METHODS
The solution proposed is based on the multivariable fuzzy temporal profile (MFTP) model, a formal model for describing certain monitoring criteria as a set of morphologies defined over the temporal evolution of the patient's physiological variables, and a set of relations between them. The MFTP model represents these morphologies through a network of fuzzy constraints between a set of points in the evolution of the variables which the physician considers especially relevant. We also provide a knowledge acquisition tool, TRACE, with which clinical staff can design and edit alarms based on the MFTP model.


RESULTS
Sixteen alarms were designed using the MFTP model; these were capable of supervising monitoring criteria that could be satisfactorily supervised with commercial monitoring devices. The alarms were validated over a total of 196h of recordings of physiological variables from 78 different patients admitted to an intensive care unit. Of the 912 alarm triggerings, only 7% were false positives. A study of the usability of the tool TRACE was also carried out. After a brief training seminar, five physicians and four nurses designed a number of alarms with this tool. They were then asked to fill in the standard System Usability Scale test. The average score was 68.2.


CONCLUSION
The proposal presented herein for describing monitoring criteria, comprising the MFTP model and TRACE, permits the supervision of monitoring criteria that cannot be represented by means of thresholds, and makes it possible to construct alarms that give a rate of false positives far below that for threshold alarms.
Elementary proof of the Routh-Hurwitz test

Abstract This note presents an elementary proof of the familiar Routh-Hurwitz test. The proof is basically one continuity argument, it does not rely on Sturm chains, Cauchy index and the principle of the argument and it is fully self-contained. In the same style an extended Routh-Hurwitz test is derived, which finds the inertia of polynomials.
Effect of common single-nucleotide polymorphisms in acetylsalicylic acid metabolic pathway genes on platelet reactivity in patients with diabetes

BACKGROUND
Platelet reactivity in patients on acetylsalicylic acid (ASA) therapy can be influenced by physiological or pathological conditions affecting ASA pharmacokinetics or pharmacodynamics. The mechanism of such variability in the therapeutic response to ASA, particularly in diabetic patients, is poorly understood. The rate of elimination of ASA and its metabolite, salicylic acid (SA), is likely a major factor determining drug efficacy. The objective of this study was to investigate the effect of genetic polymorphisms in the selected candidate genes within the ASA metabolic pathway on the platelet reactivity and concentration of ASA and thromboxane A(2) (TxA(2)) metabolites in a population of patients with type 2 diabetes mellitus (T2DM).


MATERIAL AND METHODS
The study cohort consisted of 287 Caucasians with T2DM who had been taking ASA tablets at the dose of 75 mg per day for at least 3 months. Platelet reactivity analyses were performed using VerifyNow Aspirin and PFA-100 assays. The measured ASA metabolite included salicylic acid (ASA), and TxA(2) metabolites included serum TxB(2) and urinary 11-dh-TxB(2). Genotyping for the selected 18 single-nucleotide polymorphisms (SNPs) within 5 genes of the ASA metabolic pathway was performed using a Sequenom iPLEX platform.


RESULTS
No statistically significant association was observed between the investigated SNPs genotypes, platelet reactivity, and measured metabolites in the investigated cohort of patients.


CONCLUSIONS
The results of our study failed to confirm that the selected variants in the genes within the ASA metabolic pathway might contribute to platelet reactivity in a diabetic population treated with ASA.
Cumulative mortality of Aedes aegypti larvae treated with compounds

OBJECTIVE To evaluate the larvicidal activity of Azadirachta indica, Melaleuca alternifolia, carapa guianensis essential oils and fermented extract of Carica papaya against Aedes aegypti (Linnaeus, 1762) (Diptera: Culicidae). METHODS The larvicide test was performed in triplicate with 300 larvae for each experimental group using the third larval stage, which were exposed for 24h. The groups were: positive control with industrial larvicide (BTI) in concentrations of 0.37 ppm (PC1) and 0.06 ppm (PC2); treated with compounds of essential oils and fermented extract, 50.0% concentration (G1); treated with compounds of essential oils and fermented extract, 25.0% concentration (G2); treated with compounds of essential oils and fermented extract, 12.5% concentration (G3); and negative control group using water (NC1) and using dimethyl (NC2). The larvae were monitored every 60 min using direct visualization. RESULTS No mortality occurred in experimental groups NC1 and NC2 in the 24h exposure period, whereas there was 100% mortality in the PC1 and PC2 groups compared to NC1 and NC2. Mortality rates of 65.0%, 50.0% and 78.0% were observed in the groups G1, G2 and G3 respectively, compared with NC1 and NC2. CONCLUSIONS The association between three essential oils from Azadirachta indica, Melaleuca alternifolia, Carapa guianensis and fermented extract of Carica papaya was efficient at all concentrations. Therefore, it can be used in Aedes aegypti Liverpool third larvae stage control programs.

Regular consumption of cocoa powder with milk increases HDL cholesterol and reduces oxidized LDL levels in subjects at high-risk of cardiovascular disease.

BACKGROUND AND AIMS
Epidemiological studies suggest that regular consumption of cocoa-containing products may confer cardiovascular protection, reducing the risk of coronary heart disease (CHD). However, studies on the effects of cocoa on different cardiovascular risk factors are still scarce. The aim of this study was too evaluate the effects of chronic cocoa consumption on lipid profile, oxidized low-density lipoprotein (oxLDL) particles and plasma antioxidant vitamin concentrations in high-risk patients.


METHODS AND RESULTS
Forty-two high-risk volunteers (19 men and 23 women, mean age 69.7 ± 11.5 years) were included in a randomized, crossover feeding trial. All received 40g of cocoa powder with 500 mL of skimmed milk/day(C + M) or only 500 mL/day of skimmed milk (M) for 4 weeks in a random order. Before and after each intervention period, plasma lipids, oxLDL and antioxidant vitamin concentrations were measured, as well as urinary cocoa polyphenols metabolites derived from phase II and microbial metabolisms. Compared to M, C + M intervention increases HDLc [2.67 mg/dL (95% confidence intervals, CI, 0.58-4.73; P = 0.008)] and decreases oxLDL levels [-12.3 U/L (CI,-19.3 to -5.2;P = 0.001)]. No changes between intervention groups were observed in vitamins B1, B6, B12, C and E, or folic acid concentrations. In addition, subjects who showed higher increments in urinary cocoa polyphenol metabolites exhibited significant increases in HDLc and significant decreases in oxLDL levels (P < 0.05; all).


CONCLUSIONS
Consumption of cocoa power with milk modulates the lipid profile in high-risk subjects for CHD. In addition, the relationship observed between the urinary excretion of cocoa polyphenol metabolites and plasma HDLc and oxLDL levels suggests a beneficial role for cocoa polyphenols in lipid metabolism.
Eosinophilic colitis: Case series and literature review.

INTRODUCTION
Primary eosinophilic colitis (EC) in adults is a rare and poorly studied disease, with 3 case series, 2 database-based studies and 52 case reports published to date.


METHODS
Retrospective study of all adult EC cases diagnosed in a large tertiary hospital (Hospital Clínico San Carlos, Madrid) between 2006 and 2016. We included all cases with a histopathological diagnosis of EC and we selected only those cases that were clinically recognized primary EC. We report their clinical, endoscopic and histopathological features and review the literature on this topic.


RESULTS
We identified 22 primary EC cases. Patients were mostly women (77%) with a mean age of 41 years. 4 patients (18%) had coexistent allergic diseases. Most patients consulted with diarrhea (86%) and 3 patients also suffered from rectal bleeding. Blood tests showed peripheral eosinophilia in 4 cases (18%). 19 patients had no endoscopic lesions, 2 had features of unspecific colitis and one showed features suggestive of IBD. Mean and maximum number of eosinophils per high power field ranged from 16 to 199 and 20 to 253 (mean: 48 and 70). They were mainly located in the lamina propria and most cases were associated with signs of eosinophil activation. Most patients were treated by corticosteroids, diet or budesonide and the result of treatment was generally good. No complications or recurrences were reported.


CONCLUSIONS
EC etiology and pathogenesis is unknown. Its clinical, endoscopical and imaging features are not specific, and clear histopathological criteria are lacking. Identification of signs of eosinophilic activation could be helpful.
Residual Squeeze VGG16

Deep learning has given way to a new era of machine learning, apart from computer vision. Convolutional neural networks have been implemented in image classification, segmentation and object detection. Despite recent advancements, we are still in the very early stages and have yet to settle on best practices for network architecture in terms of deep design, small in size and a short training time. In this work, we propose a very deep neural network comprised of 16 Convolutional layers compressed with the Fire Module adapted from the SQUEEZENET model. We also call for the addition of residual connections to help suppress degradation. This model can be implemented on almost every neural network model with fully incorporated residual learning. This proposed model Residual-Squeeze-VGG16 (ResSquVGG16) trained on the large-scale MIT Places365-Standard scene dataset. In our tests, the model performed with accuracy similar to the pre-trained VGG16 model in Top-1 and Top-5 validation accuracy while also enjoying a 23.86% reduction in training time and an 88.4% reduction in size. In our tests, this model was trained from scratch.

A PRECISE, LOW-COST RTK GNSS SYSTEM FOR UAV APPLICATIONS

High accuracy with real-time positioning of moving objects has been considered a standard task of engineering geodesy for 10 to 15 years. An absolute positioning accuracy of 1-3 cm is generally possible worldwide and is further used in many areas of machine guidance (machine control and guidance), and farming (precision farming) as well as for various special applications (e.g. railway trolley, mining, etc.). The cost of the measuring instruments required for the use of geodetic L1/L2 receivers with a local reference station amounts to approximately USD 30,000 to 50,000. Therefore, dual frequency RTK GNSS receivers are not used in the mass market. Affordable GPS/GNSS modules have already reached the mass market in various areas such as mobile phones, car navigation, the leisure industry, etc. Kinematic real-time positioning applications with centimetre or decimetre levels could also evolve into a mass product. In order for this to happen, the costs for such systems must lie between USD 1,000 to 2,000. What exactly low-cost means is determined by the precise specifications of the given individual application. Several university studies in geodesy focus on the approach of high-accuracy positioning by means of single frequency receivers for static applications [e.g. GLABSCH et. al. 2009, SCHWIEGER and GLÄSER 2005, ALKAN 2010, REALINI et. al. 2010, KORTH and HOFMANN 2011]. Although intelligent approaches have been developed that compute a trajectory in the post-processing mode [REALINI et. al., 2010], at present, there are only a very few GNSS Low-Cost Systems that enable real-time processing. This approach to precise position determination by means of the computation of static raw data with single frequency receivers is currently being explored in a research project at the Beuth Hochschule für Technik Berlin and is being further developed for kinematic applications. The project is embedded in the European Social Fund. It is a follow-up project in the area of static positioning with single GNSS frequency receivers [KORTH and HOFMANN, 2011].
Equilibrium Isotherm Studies of Methylene Blue Adsorption onto Activated Carbon Prepared from Delonix regia Pods

The adsorption capacity of Methylene blue from aqueous solution onto activated carbon prepared from Delonix regia pods (Flame tree pods) was investigated under various experimental conditions. Batch mode experiments were conducted to assess the potential of the above activated carbon for the removal of Methylene blue from aqueous solution. Equilibrium isotherm studies have been done by varying the following three parameters: initial concentration of Methylene blue dye solution, volume of the dye solution, and adsorbent dose on the uptake of dye from the solution. Non-linear analysis was used to compare the best-fitting isotherms. The equilibrium data obtained were fitted to Langmuir, Freundlich, and RedlichPeterson isotherm models.
Decision Trees

Decision Trees are considered to be one of the most popular approaches for representing classifiers. Researchers from various disciplines such as statistics, machine learning, pattern recognition, and Data Mining have dealt with the issue of growing a decision tree from available data. This paper presents an updated survey of current methods for constructing decision tree classifiers in a top-down manner. The chapter suggests a unified algorithmic framework for presenting these algorithms and describes various splitting criteria and pruning methodologies.
An Interactive FORTRAN Structuring Aid

This paper describes a tool at the Jet Propulsion Laboratory which aids a programmer in converting FORTRAN to a structured syntax. The program is a highly interactive system using computer graphics techniques to facilitate the operations necessary for such a conversion. Editing and structure recognition capabilities, including the ability to handle arbitrary levels of block structure, have been combined into a system that reduces the effort involved in updating old software.
Three-year duration of benefit from abciximab in patient receiving stents for acute myocardial infarction in the randomized double-blind ADMIRAL study.

We have read carefully Dr Kanna’s comments trying to perform a critical appraisal of our manuscript, but it appears that most of these critics are inaccurate. Potential confounders such as coronary risk factors are important to consider, but by definition randomization is used to balance the different groups and the ADMIRAL study was randomized and the two study groups were well balanced for all baseline characteristics. Treatment compliance, another concern in Dr Kanna’s letter, is unlikely to be an issue because abciximab is administered intravenously for 12 h during and immediately after PCI and of course there was no further study drug administration during the 3-year follow-up of the ADMIRAL study. Blinded evaluation is another criterion of quality for studies and an issue in the letter; however, this critic does not apply to our study: of all randomized studies testing abciximab in primary stenting of STEMI, ADMIRAL remains, so far, the only double blind study. Moreover, the 3-year follow-up was performed blindly as indicated in Methods. The following concern in the letter is about the validity of self-reporting data in patient questionnaires but as we indicated this was not the only mode of data collection, and physicians were surveyed, medical records consulted . . . and for hard endpoints, especially mortality which was the main objective, self-reporting is clearly not an issue. Finally, the author does not concur with the conclusions of a favourable effect of abciximab in primary stenting of ST-elevation MI. However, ADMIRAL is a positive study for its primary hypothesis showing the superiority of the study drug over placebo to reduce death, re-infarction, and urgent revascularization at 30 days, confirmed also at 6 months. Because we believe that it is important to provide information on the longterm, a three-year follow-up was conducted to determine whether the benefit observed initially was preserved; we acknowledged that the study was not powered to detect a difference in hard clinical endpoints at 3 years. However, the expression of the results with Kaplan–Meier curves demonstrated the preservation of the initial absolute benefit, with two parallel curves for death or MI, over 3 years. Our data along with other studies confirm the benefit of GPIIbIIIa inhibition with abciximab in primary PCI. Meta-analyses have also shown a significant impact on mortality and a greater benefit when the drug is administered early. All guidelines recommend its use in primary PCI.
Virtual reality in the chemical engineering classroom

Virtual reality, VR, is an emerging computer interface that utilizes immersive interactive threedimensional graphics as well as audio, psychology, special hardware, and numerous other mechanisms to produce simulations so realistic that users believe (Êif only for a few momentsÊ) that what they are experiencing is ÒrealÓ [1]. In addition to high-speed graphics, VR can be enhanced through wired clothing, body tracking sensors, tactile and force feedback systems, spatialized sound, and even olfactory displays. Some of the earliest uses of VR have been in medical and military applications, where budgets are large and the consequences of even small errors are sufficient to justify the expense of high-quality equipment and initial software development. More recently VR has been used for computational fluid dynamics visualization, operator training, construction engineering, maintenance planning, and EPA site remediation.
