Computer Checks on Human Analyses of the KRKB Endgame

The two senior authors, confono to their intention of making the ICCA Journal a repository of database results (Herschberg and Van den Herik, 1985a), are happy to report the detailed outcome of the undergraduate research of the two junior authors on the KRKB endgame. As far back as 1970, Strohlein (1970), in his Ph.D. thesis, had constructed a KRKB database. However, he did not reveal the number of won and drawn positions, nor, apparently, was there a facility to check published analyses by human authors against the database. The research to be reported was inspired, in part, by the publication, in Dutch, of Spinhoven and Bondarenko (1983). This book encompasses 24 studies in this endgame (Chapter 1) and our curiosity was challenged to detenoine whether some non-optimal variations were published or, more seriously, whether the studies would be correct in their assigning of games as drawn or won. A database was constructed according to the principles published in Vanden Herik and Herschberg (1985) and using the software for database construction then available at the Delft University of Technology.
Model predictive control and PID for path following of an unmanned quadrotor helicopter

This paper presents a control method based on Model Predictive Control (MPC) and PID for path following of a quadrotor unmanned aerial vehicle (UAV). On the basis of simplified kinetic model, a double loop control structure is adopted. Because MPC method is ability to deal with input and output constraints, in the outer loop (position loop), MPC controllers are designed to track the reference trajectory under input or output physical constrains. In the inner loop (attitude loop), to achieve rapid response for attitude, PID controllers are designed to track the reference attitude. The simulation results validate the effectiveness of the proposed control approach.
A comparison of neurotransmitter-specific and neuropeptide-specific neuronal cell types present in the dorsal cortex in turtles with those present in the isocortex in mammals: implications for the evolution of isocortex.

Although it seems highly likely that mammalian isocortex evolved from a structure resembling reptilian telencephalic cortex, it has been uncertain if this occurred by the laminar differentiation of three-layered reptilian cortex into six-layered mammalian isocortex without the addition of new cell types or by laminar differentiation with the addition of new cell types. To distinguish between these two possibilities, immunohistochemical techniques were used to study turtles to see if the same major neuronal cell types, as defined by neurotransmitter or neuropeptide content, present in mammalian isocortex are also present in the specific part of reptilian cortex thought to be the forerunner of at least parts of isocortex, namely the dorsal cortex. Neurons containing the following substances are the major transmitter-specific types of neurons known to be present in mammalian isocortex: cholecystokinin-8 (CCK8), vasoactive intestinal polypeptide (VIP), acetylcholine, substance P (SP), neuropeptide Y (NPY), somatostatin (SS), LANT6, enkephalin, GABA and glutamate (GLUT). In turtles, only those of the above substances that are found in large numbers of neurons in layers V-VI in mammalian isocortex, irrespective of whether they are also present in layers II-IV (i.e. SP, NPY, SS, LANT6, GABA and GLUT), were present in neurons in dorsal cortex. The neurons containing these substances in dorsal cortex in turtles were generally highly similar in morphology to their counterparts in mammalian isocortex. In contrast, neurons labeled for CCK8, VIP or acetylcholine, which are mainly found in neurons of layers II-IV of mammalian isocortex, were absent or extremely rare in dorsal cortex. The absence or paucity of neurons labeled for these latter substances in dorsal cortex in turtles did not reflect an overall staining failure of the antisera used since the same antisera yielded excellent labeling of neurons, fibers and terminals in many other brain regions in turtles. Thus, dorsal cortex in turtles appears to lack several of the major cell types characteristic of layers II-IV of mammalian isocortex, but possesses a number of the major cell types characteristic of layers V-VI of isocortex. The findings support and extend a previous suggestion by Ebner [1976], based on hodological data, that dorsal cortex in turtles may lack the types of neurons found in the more superficial layers of mammalian isocortex.

Mechanisms of TNF receptor‐associated factor (TRAF) regulation in B lymphocytes

A key component of signaling by members of the tumor necrosis factor receptor (TNF‐R) family is interaction with the cytoplasmic adapter proteins known as TRAFs. Several proteins encoded by microbes also interact with TRAFs. A notable example is the CD40 receptor, expressed on antigen presenting cells and providing key activation signals in T cell‐dependent B cell activation. CD40 signals to B cells are mimicked by a constitutively active viral protein produced by the Epstein‐Barr virus. For each of these receptors, multiple mechanisms of TRAF regulation contribute to signal transduction and the ultimate effect on the B cell. Recent findings concerning these regulatory mechanisms are summarized in this overview.
Efficacy and safety of adrenocorticotropic hormone gel in refractory dermatomyositis and polymyositis

Aim To evaluate the efficacy, safety, tolerability and steroid-sparing effect of repository corticotropin injection (RCI), in an open-label clinical trial, in refractory adult polymyositis (PM) and dermatomyositis (DM). Methods Adults with refractory PM and DM were enrolled by two centres. Inclusion criteria included refractory disease defined as failing glucocorticoid and/or ≥1 immunosuppressive agent, as well as active disease defined as significant muscle weakness and >2 additional abnormal core set measures (CSMs) or a cutaneous 10 cm Visual Analogue Scale score of ≥3 cm and at least three other abnormal CSMs. All patients received RCI of 80 units subcutaneously twice weekly for 24 weeks. The primary end point for the trial was the International Myositis Assessment and Clinical Studies definition of improvement. Secondary end points included safety, tolerability, steroid-sparing as well as the 2016 American College of Rheumatology (ACR)/European League Against Rheumatism myositis response criteria (EULAR) Results Ten of the 11 enrolled subjects (6 DM, 4 PM) completed the study. Seven of 10 met the primary end point of efficacy at a median of 8 weeks. There was a significant decrease in prednisone dose from baseline to conclusion (18.5 (15.7) vs 2.3 (3.2); P<0.01). Most individual CSMs improved at week 24 compared with the baseline, with the muscle strength improving by >10% and the physician global by >40%. RCI was considered safe and tolerable. No patient developed significant weight gain or an increase of haemoglobin A1c or cushingoid features. Conclusion Treatment with RCI was effective in 70% of patients, safe and tolerable, and led to a steroid dose reduction in patients with adult myositis refractory to glucocorticoid and traditional immunosuppressive drugs. Trial registration number NCT01906372; Results.
Nonsurgical Strategies to Reduce Mortality in Patients Undergoing Cardiac Surgery: An Updated Consensus Process.

OBJECTIVE A careful choice of perioperative care strategies is pivotal to improve survival in cardiac surgery. However, there is no general agreement or particular attention to which nonsurgical interventions can reduce mortality in this setting. The authors sought to address this issue with a consensus-based approach. DESIGN A systematic review of the literature followed by a consensus-based voting process. SETTING A web-based international consensus conference. PARTICIPANTS More than 400 physicians from 52 countries participated in this web-based consensus conference. INTERVENTIONS The authors identified all studies published in peer-reviewed journals that reported on interventions with a statistically significant effect on mortality in the setting of cardiac surgery through a systematic Medline/PubMed search and contacts with experts. These studies were discussed during a consensus meeting and those considered eligible for inclusion in this study were voted on by clinicians worldwide. MEASUREMENTS AND MAIN RESULTS Eleven interventions finally were selected: 10 were shown to reduce mortality (aspirin, glycemic control, high-volume surgeons, prophylactic intra-aortic balloon pump, levosimendan, leuko-depleted red blood cells transfusion, noninvasive ventilation, tranexamic acid, vacuum-assisted closure, and volatile agents), whereas 1 (aprotinin) increased mortality. A significant difference in the percentages of agreement among different countries and a variable gap between agreement and clinical practice were found for most of the interventions. CONCLUSIONS This updated consensus process identified 11 nonsurgical interventions with possible survival implications for patients undergoing cardiac surgery. This list of interventions may help cardiac anesthesiologists and intensivists worldwide in their daily clinical practice and can contribute to direct future research in the field.
Co-Time Co-Frequency Full-Duplex Visible Light On-Chip Communication Using a Pair of InGaN/GaN Quantum-Well Diodes

Co-time co-frequency full-duplex (CCFD) communication is challenging for radio frequency communications due to the overwhelming self- interference. For visible light communications, it was reported that two light-emitting diodes could construct a half-duplex communication link, but no CCFD communication using two diodes have been realized. In this work, we introduce an on-chip CCFD system using a pair of micrometer-scale InGaN/GaN multiple quantum-well diodes, which can detect and emit light at the same time. Maximum-likelihood estimator is derived and applied to extract the useful signal from the received mixed signal. The proposed CCFD system provides a promising way to decrease the size of on-chip optical communication systems and portable optical communication devices, and it can also reduce the number of optical devices in optical fiber communications and wireless optical communications without introducing much extra cost.
Dynamics and locomotion of flexible foils in a frictional environment

Over the past few decades, oscillating flexible foils have been used to study the physics of organismal propulsion in different fluid environments. Here, we extend this work to a study of flexible foils in a frictional environment. When the foil is oscillated by heaving at one end but is not free to locomote, the dynamics change from periodic to non-periodic and chaotic as the heaving amplitude increases or the bending rigidity decreases. For friction coefficients lying in a certain range, the transition passes through a sequence of N-periodic and asymmetric states before reaching chaotic dynamics. Resonant peaks are damped and shifted by friction and large heaving amplitudes, leading to bistable states. When the foil is free to locomote, the horizontal motion smoothes the resonant behaviours. For moderate frictional coefficients, steady but slow locomotion is obtained. For large transverse friction and small tangential friction corresponding to wheeled snake robots, faster locomotion is obtained. Travelling wave motions arise spontaneously, and move with horizontal speeds that scale as transverse friction coefficient to the power 1/4 and input power that scales as the transverse friction coefficient to the power 5/12. These scalings are consistent with a boundary layer form of the solutions near the foil’s leading edge.
Edge states of hydrogen terminated monolayer materials: silicene, germanene and stanene ribbons

We investigate the energy dispersion of the edge states in zigzag silicene, germanene and stanene nanoribbons with and without hydrogen termination based on a multi-orbital tight-binding model. Since the low buckled structures are crucial for these materials, both the π and σ orbitals have a strong influence on the edge states, different from the case for graphene nanoribbons. The obtained dispersion of helical edge states is nonlinear, similar to that obtained by first-principles calculations. On the other hand, the dispersion derived from the single-orbital tight-binding model is always linear. Therefore, we find that the non-linearity comes from the multi-orbital effects, and accurate results cannot be obtained by the single-orbital model but can be obtained by the multi-orbital tight-binding model. We show that the multi-orbital model is essential for correctly understanding the dispersion of the edge states in tetragen nanoribbons with a low buckled geometry.
Gap in Capillary Perfusion on Optical Coherence Tomography Angiography Associated With Persistent Macular Edema in Branch Retinal Vein Occlusion.

Purpose To evaluate correlations between persistent macular edema associated with branch retinal vein occlusion (BRVO) and the macular perfusion status in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) using optical coherence tomography angiography (OCTA). Methods Retrospective, case-control study. Twenty patients with BRVO followed for 12 months or more were enrolled. Persistent macular edema was defined as central retinal thickness exceeding 300 μm that persisted or recurred less than 3 months after the final treatment. We compared two groups (i.e., seven eyes with persistent macular edema and 13 eyes without macular edema). The macular perfusion status was evaluated using OCTA. We defined a gap vessel as a residual vessel in the SCP that existed simultaneously with capillary loss in the DCP. The gap vessels were determined by subtracting the vessel images of the DCP from the images of the SCP using an image processing technique. Results In eyes with persistent macular edema, the area with gap vessels was significantly (P = 0.0013) larger than in eyes without macular edema (14.34% vs. 8.02%). Other factors evaluated (i.e., the area of the foveal avascular zone, superficial vessel density, and deep vessel density) did not differ significantly (P = 0.66, P = 0.23, P = 0.34, respectively) between the groups. Conclusions The difference in capillary loss between the SCP and DCP can facilitate development of persistent macular edema in BRVO.

This paper describes in detail how to apply the MBO algorithm for proper tuning of the PID controller parameters with objective function as Integral Square Error (ISE). In the simulation results, step response of proposed AVR system compared with Particle Swarm Optimization (PSO), Many Optimizing Liaisons (MOL), Chaotic PSO (CPSO), Chaotic Ant Swarm (CAS), optimization techniques in terms of settling time and peak amplitude and also check the performance indices in terms of ITAE, IAE, ISE functions.
Location category classification using tree based models with novelty discrimination

As a result of the vast amount of location data, and the variety of the location based social network types such as Facebook check-ins and Foursquare. Many questions raised to enhance the quality of these networks, one important question is, which activity is the user going to, we formulated this as the prediction of the next location semantics, or the category. This feature would help service providers, to personalize the marketing campaigns and to enhance other problems results, such as the next location prediction. In order to solve this task, we divided it into two subtasks; first, to develop a model for novelty prediction, second to use its results to predict the next location. The predication task considers two cases of prediction; regular places (visited before) and novel places (never visited before). The predication accuracy of the proposed approach yields high accuracy of 86.7%, for regular places and an accuracy of 38.4% for novel places.
Comparative study on AES and RSA algorithm for medical images

Scalability of network with the expanding number of system a data exchange is crucial to permit secure information transmission in the network environment. The sending information or image may defiled by any outsider on the off chance that it is not secured. In medical field it is essential to secure the data or images. There are many techniques available to ensure the security of images in medical field like RSA, AES, and Watermarking. RSA is a public key cryptographic technique, makes use of pair of keys (public key, private key) and AES is a private key cryptosystem and is based on Substitution Permutation Network Using these techniques the host can encrypt and decrypt the image and can keep digital images safe. Watermarking is the process of hiding the information in any multimedia for the authentication and confidentiality of data. This paper recommends which is the best method among various techniques by considering every one of the techniques. By contrasting the different systems this paper can arrive at a conclusion that which is the best methods to guarantee the security of image.
A “Sit Less, Walk More” Workplace Intervention for Office Workers: Long-Term Efficacy of a Quasi-Experimental Study

Objective: This study tested the maintenance outcomes of a 3-month Sit Less, Walk More (SLWM) workplace intervention for office workers compared with usual care at 12 months from the baseline. Method: A quasi-experimental study was conducted in two workplaces. The intervention group (n = 51) received multi-component intervention and the comparison group (n = 50) received newsletters only. The outcomes of the study (self-reported psychosocial, physical activity, sitting, and lost productivity; objectively measured cardiometabolic biomarkers) were compared at baseline, 3, and 12 months. Results: Generalized estimating equations analyses found that the intervention group had significant improvements in self-regulation for sitting less and moving more (P = 0.017), walking (P = 0.003), weight (P = 0.013), waist circumference (P = 0.002), and insulin (P = 0.000) at 12 months compared with the comparison group. Conclusion: The SLWM intervention was effective in improving self-regulation, walking, and some cardiometabolic biomarkers in office workers.
Correlation between neutrophil-to-lymphocyte ratio and severity scores in septic patients upon hospital admission. A series of 50 patients

Abstract Introduction. The neutrophil-to-lymphocyte ratio (NLR) as calculated from the white cell differential blood count is a marker that has been used as a prognostic index when assessing patients suffering from several clinical syndromes, including sepsis. The aim of this study was to evaluate the relationship between NLR and the commonly used severity scores of sepsis SOFA, APACHE II and SAPS II in a population of emergency admitted adult patients with sepsis in a tertiary center. Methods. A prospective observational study was conducted in the Emergency Department of the University Hospital of Patras, Greece, based on data extracted from 50 patients consecutively enrolled, suffering from sepsis of multiple origin. The study period was from May 01, 2017 until June 30, 2017. The NLR was calculated from the total white blood cell (WBC) count values measured from a peripheral venous blood specimen drawn on admission. C-reactive protein (CRP) was also measured. The sepsis severity prognostic scores APACHE II, SAPS II and SOFA were calculated for each patient. Results. NLR was positively correlated with the sepsis severity prognostic scores on admission (SOFA, rs = 0.497, p < 0.001; APACHE II, rs = 0.411, p = 0.003; SAPS II, rs = 0.445, p = 0.001). Total WBC was also significantly correlated with the scores (SOFA, rs = 0.342, p = 0.015; APACHE II, rs = 0.384, p = 0.006; SAPS II, rs = 0.287, p = 0.043). Serum CRP did not show any significant correlation either to NLR or to the sepsis severity scores on admission. Conclusions. NLR is an easily calculated, cost-efficient index that could be used as a tool for clinicians when assessing sepsis patients in the Emergency Department. Although NLR measurement is simple, and rapidly available, future and larger prospective studies are warranted to confirm its definite value as a prognostic index in sepsis patients.
Inhibition of Salivary Amylase by Black and Green Teas and Their Effects on the Intraoral Hydrolysis of Starch

Tea decoctions prepared from a number of black and green teas inhibited amylase in human saliva. Black teas gave higher levels of inhibition than green teas, and removal of tea tannins with gelatin led to the loss of inhibitory activity from all decoctions. Streptococcal amylase was similarly inhibited by tea decoctions. Fluoride was without effect on amylase. Since salivary amylase hydrolyzes food starch to low molecular weight fermentable carbohydrates, experiments were carried out to determine whether tea decoctions would interfere with the release of maltose in food particles that became entrapped on the dentition. Subjects consumed salted crackers and rinsed subsequently for 30 s with black or green tea decoctions, or water. Maltose release was reduced by up to about 70% after rinsing with the teas. Black tea decoction was significantly more effective than green tea, in agreement with the in vitro data. The observations supported the hypothesis that tea consumption can be effective in reducing the cariogenic potential of starch-containing foods such as crackers and cakes. Tea may reduce the tendency for these foods to serve as slow-release sources of fermentable carbohydrate.
Factors affecting the adsorption of salivary acidic proline-rich proteins to hydroxyapatite.

This study was undertaken to evaluate variations in the adsorption of acidic proline-rich proteins to hydroxyapatite seen in different types of saliva. The presence of other proteins in saliva significantly decreased the adsorption of the acidic proline-rich proteins. Adsorption to hydroxyapatite of varying concentrations of two of these proteins, A and C revealed that differences in concentration of acidic proline-rich proteins could at least partly explain the previously observed variations in adsorption. The amount of adsorbed protein decreased with increased concentration of inorganic phosphate. pH and physiological variations in ionic strength had a small effect on the adsorption of proteins A and C.
Overall and specific migration from multilayer high barrier food contact materials – kinetic study of cyclic polyester oligomers migration

ABSTRACT Most multilayer high barrier materials used in food packaging have a polyurethane adhesive layer in their structures. In order to assess the safety of these materials, it is important to determine the compounds intentionally added to the adhesives (IAS) as well as those non-intentionally added substances (NIAS). During the manufacture of polyurethane adhesives, some by-products can be formed, such as cyclic polyester oligomers coming from the reaction between dicarboxylic acids and glycols. Since these compounds are not listed in the Regulation 10/2011/EU, they should not be found in migration above 0.01 mg/kg of simulant. In this study two flexible multilayer packaging materials were used and migration was evaluated in simulant A (ethanol 10% v/v), simulant B (acetic acid 3% w/v) and simulant ethanol 95% v/v during 10 days at 60ºC. Identification and quantification of non-volatile compounds was carried out by UPLC-MS-QTOF. Most of migrants were oligomers such as cyclic polyesters and caprolactam oligomers. Overall migration and specific migration of adipic acid-diethylene glycol and phthalic acid-diethylene glycol were monitored over time and analysed by UPLC-MS-TQ. In most cases, ethanol 95% v/v was the simulant with the highest concentration values. Overall migration kinetics followed a similar pattern than specific migration kinetics.
