Impact of pricing structure on supply chain coordination with cooperative advertising
Authors: Sadjadi Seyed Jafar , Alirezaee Amin
Published: November 2019

This paper develops a game-theoretic model in a two-echelon supply chain composed of one manufacturer and two retailers to study the effect of pricing structure and cooperative-advertising decisions on the supply chain coordination performance. In the proposed model, different pricing structures are analyzed and then, two types of pricing structure in supply chain coordination mechanisms are presented, in addition to considering four possible scenarios for pricing structure. For the first two scenarios, retailers determine the retail prices, while in the other two ones, the sales price is set by the manufacturer. Therefore, the retailers are obliged to comply with this rule. The manufacturer-Stackelberg and the cooperative games are formulated for each scenario by considering key assumptions associated with advertising expenditures to maintain the potential demand size. This paper also presents some analytical results and determines the equilibrium of the models for each scenario. Finally, a numerical analysis is conducted to illustrate the impact of pricing structure on the optimal decision variables and the profit of the supply chain members.

Published: November 2019

In this study one obtained the optimal decision of a retailer for the replenishment rate with selling-price and credit-period dependent demand to maximize the profit. A time-varying deterioration rate was considered for those products. A credit-period was offered by the retailer to the end customer to settle the whole payments. The aim of the model was to obtain the maximum profit for the retailer based model. A solution methodology with an algorithm was used to obtain the global optimum profit. An illustrative numerical example was given to test the practical applicability of the model. Numerical study indicated that the profit was at a maximum when the permissible delay-period for payment offered by the suppliers was lies between the permissible delay-time, and the cycle time, offered by the retailer.

Das im Jahr 2004 eingeführte „Verfahren Haut“ der Deutschen Gesetzlichen Unfallversicherung (DGUV) sieht bei schweren, ambulant therapieresistenten berufsbedingten Hauterkrankungen vor, im Rahmen eines gestuft gegliederten Präventionskonzeptes eine Individualpräventionsmaßnahme durchzuführen, die sich aus einem dreiwöchigen stationären Aufenthalt mit einem interdisziplinären medizinischen und pädagogischen Interventionsprogramm und einer engmaschigen nachstationären ambulanten hautärztlichen Betreuung zusammensetzt. Diese Maßnahme (Tertiäre Individual-Prävention, TIP) wurde u. a. maßgeblich im Institut für interdisziplinäre Dermatologische Prävention und Rehabilitation (iDerm) an der Universität Osnabrück konzipiert und evaluiert und stellt hier einen Schwerpunkt des täglichen Wirkens dar. Mittels Langzeitevaluation der Verläufe nach TIP über einen Zeitraum von 5 Jahren konnte gezeigt werden, dass das Maßnahmenprogramm effektiv ist und der deutlichen Mehrheit der Teilnehmer erlaubt, trotz ursprünglich schwerer Berufsdermatose die berufliche Tätigkeit dauerhaft auszuüben bei gleichzeitig langfristig signifikanter Besserung des Hautbefundes und der Lebensqualität. Die im iDerm an der Universität Osnabrück angebotene stationäre Rehabilitationsmaßnahme TIP steht allen Versicherten der Unfallversicherungsträger in der Bundesrepublik Deutschland zur Verfügung; die Indikation hierfür kann problemlos durch die behandelnden Hautärztinnen und Hautärzte im Hautarztberichtsformular gestellt werden.

Published: November 2019

Background and Objectives: Neurinoma arising from other than nonvestibular cranial nerves is less prevalent. Here we present our experiences regarding the clinical profile, investigations, microneurosurgical management, and the outcome of nonvestibular cranial nerve neurinomas. Materials and Methods: From January 2005 to December 2011, the recorded documents of operated nonvestibular intracranial neurinomas were retrospectively studied for clinical profile, investigations, microneurosurgical management, complications, follow-up, and outcomes. Results: The average follow-up was 24.5 months. Total number of cases was 30, with age ranging from 9 to 60 years. Sixteen cases were males and 14 were females. Nonvestibular cranial nerve schwannomas most commonly originated from trigeminal nerve followed by glossopharyngeal+/vagus nerve. There were three abducent nerve schwannomas that are very rare. There was no trochlear nerve schwannoma. Two glossopharyngeal+/vagus nerve schwannomas extended into the neck through jugular foramen and one extended into the upper cervical spinal canal. Involved nerve dysfunction was a common clinical feature except in trigeminal neurinomas where facial pain was a common feature. Aiming for no new neurodeficit, total resection of the tumor was done in 24 cases, and near-total resection or gross total resection or subtotal resection was done in 6 cases. Preoperative symptoms improved or disappeared in 25 cases. New persistent deficit occurred in 3 cases. Two patients died postoperatively. There was no recurrence of tumor till the last follow-up. Conclusion: Nonvestibular schwannomas are far less common, but curable benign lesions. Surgical approach to the skull base and craniovertebral junction is a often complex and lengthy procedure associated with chances of significant morbidity. But early diagnosis, proper investigations, and evaluation, along with appropriate decision making and surgical planning with microsurgical techniques are the essential factors that can result in optimum outcome.
Gyro-kinetic theory and global simulations of the collisionless tearing instability: The impact of trapped particles through the magnetic field curvature
Authors: Zarzoso D. , Nasr S. , Garbet X. , Smolyakov A. I. , Benkadda S.
Published: November 2019

The linear instability of the tearing mode is analyzed using a gyrokinetic approach within a Hamiltonian formalism, where the interaction between particles and the tearing mode through the wave-particle resonance is retained. On the one hand, the curvature of the magnetic field is shown to play no role in the linear instability when only passing particles are present in the plasma. On the other hand, the presence of trapped particles leads to an overall increase in the growth rate. Gyrokinetic simulations using the state-of-the-art Gkw code confirm these findings and are further used to investigate the impact of the magnetic field curvature and the temperature gradient on tearing modes including the effect of trapped particles. Without the temperature gradient, wave-particle resonance with the trapped electrons tends to stabilize the tearing mode, while with the finite temperature gradient, the magnetic curvature tends to destabilize the tearing mode, suggesting an interchange mechanism. The balance of these two stabilizing/destabilizing effects leads to a threshold in the temperature gradient beyond which the magnetic curvature plays a destabilizing role. This opens the way for a deeper understanding and control of the tearing instability in fusion plasmas.

The WD40-repeat protein WDR5 scaffolds various epigenetic writers and is a critical component of the mammalian SET/MLL histone methyltransferase complex. Dysregulation of the MLL1 catalytic function is associated with mixed-lineage leukemia, and antagonism of the WDR5-MLL1 interaction by small molecules has been proposed as a therapeutic strategy for MLL-rearranged cancers. Small molecule binders of the “WIN” site of WDR5 that cause displacement from chromatin have been additionally implicated to be of broader use in cancer treatment. In this study, a fragment screen with Surface Plasmon Resonance (SPR) was used to identify a highly ligand-efficient imidazole-containing compound that is bound in the WIN site. The subsequent medicinal chemistry campaign—guided by a suite of high-resolution cocrystal structures with WDR5—progressed the initial hit to a low micromolar binder. One outcome from this study is a moiety that substitutes well for the side chain of arginine; a tripeptide containing one such substitution was resolved in a high resolution structure (1.5 Å) with a binding mode analogous to the native tripeptide. SPR furthermore indicates a similar residence time (kd = ∼0.06 s−1) for these two analogs. This novel scaffold therefore represents a possible means to overcome the potential permeability issues of WDR5 ligands that possess highly basic groups like guanidine. The series reported here furthers the understanding of the WDR5 WIN site and functions as a starting point for the development of more potent WDR5 inhibitors that may serve as cancer therapeutics.
Thermal versus mechanical unfolding in a model protein
Authors: Tapia-Rojo Rafael , Mazo Juan J. , Falo Fernando
Published: November 2019

Force spectroscopy techniques are often used to learn about the free energy landscape of single biomolecules, typically by recovering free energy quantities that, extrapolated to zero force, are compared to those measured in bulk experiments. However, it is not always clear how the information obtained from a mechanically perturbed system can be related to the information obtained using other denaturants since tensioned molecules unfold and refold along a reaction coordinate imposed by the force, which is not likely to be meaningful in its absence. Here, we explore this dichotomy by investigating the unfolding landscape of a model protein, which is unfolded first mechanically through typical force spectroscopy-like protocols and next thermally. When unfolded by nonequilibrium force extension and constant force protocols, we recover a simple two-barrier landscape as the protein reaches the extended conformation through a metastable intermediate. Interestingly, folding-unfolding equilibrium simulations at low forces suggested a totally different scenario, where this metastable state plays little role in the unfolding mechanism, and the protein unfolds through two competing pathways [R. Tapia-Rojo et al., J. Chem. Phys. 141, 135102 (2014)]. Finally, we use Markov state models to describe the configurational space of the unperturbed protein close to the critical temperature. The thermal dynamics is well understood by a one-dimensional landscape along an appropriate reaction coordinate, however it is very different from the mechanical picture. In this sense, the results of our protein model for the mechanical and thermal descriptions provide incompatible views of the folding/unfolding landscape of the system, and the estimated quantities to zero force result are hard to interpret.

Obstructive sleep apnea screening by heart rate variability-based apnea/normal respiration discriminant model
Authors: Nakayama Chikao , Fujiwara Koichi , Sumi Yukiyoshi , Matsuo Masahiro , Kano Manabu , Kadotani Hiroshi
Published: November 2019

Objective: Obstructive sleep apnea (OSA) is a common sleep disorder; however, most patients are undiagnosed and untreated because it is difficult for patients themselves to notice OSA in daily living. Polysomnography (PSG), which is the gold standard test for sleep disorder diagnosis, cannot be performed in many hospitals. This fact motivates us to develop a simple system for screening OSA at home. Approach: The autonomic nervous system changes during apnea, and such changes affect heart rate variability (HRV). This work develops a new apnea screening method based on HRV analysis and machine learning technologies. An apnea/normal respiration (A/N) discriminant model is built for respiration condition estimation for every heart rate measurement, and an apnea/sleep ratio is introduced for final diagnosis. A random forest is adopted for the A/N discriminant model construction, which is trained with the PhysioNet apnea-ECG database. Main results: The screening performance of the proposed method was evaluated by applying it to clinical PSG data. Sensitivity and specificity achieved 76% and 92%, respectively, which are comparable to existing portable sleep monitoring devices used in sleep laboratories. Significance: Since the proposed OSA screening method can be used more easily than existing devices, it will contribute to OSA treatment.

Published: November 2019

The propagation characteristic of two identical and parallel dark solitons in a silicon-on-insulator (SOI) waveguide is simulated numerically using the split-step Fourier method. The parallel dark solitons imposed by the initial chirp are investigated mainly by changing their power, their relative time delay. The simulation shows that the time delay deforms the parallel dark soliton pulse, forming a bright-like soliton in the transmission process and making the transmission quality down. By increasing the power of one dark soliton, the energy of the other dark soliton can be increased, and larger increase in a soliton’s power leads to larger increase in the energy of the other. When the initial chirp is introduced into one of the dark solitons, higher energy consumption is observed. In particular, positive chirps resulting in pulse broadening width while negative chirps narrowing, with an obvious compression effect on the other dark soliton. Finally, large negative chirps are found to have a profound impact on parallel and nonparallel dark solitons.

Published: November 2019

This research study employed a quasi-experimental design of two groups using pretest-posttest. Two groups were assigned to different treatments; the Control Group stayed inside the classroom while the Experimental group was exposed to community service. The manner of groupings was based on the randomized design lottery method technique. Results revealed that there was a significant difference in the student academic performance of the BS Biology students after the intervention using community service as a teaching method. Furthermore, the data gathered were triangulated using Focus Group Discussion (FGD) from the respondents, specifically personal reflections, observations, and in-depth interviews to the students and the residents of Barangay Daculan, Estancia, Iloilo. This implied that the conduct of the intervention brought significant effects to the student academic performance — likewise, the people of Brgy. Daculan has widened their perspective, awareness, and familiarity towards their surroundings after the series of lectures conducted in the community. Therefore, it can be stated that community service, when used as a teaching method, was highly effective to both students and community as revealed in the post-test results of students’ academic performance, the intervention improved the quality of instruction when used as a teaching method through community services.

Abstrak

The main thrust of this study was to determine the effectiveness of the Orton-Gillingham approach in the reading ability of Grade I pupils. Moreover, it proposed an action plan to integrate the use of the Orton-Gillingham approach in teaching reading. The study utilized the pretest-posttest quasi-experimental design. The pretest scores pairing with 24 respondents in each group determined the grouping of the respondents. Orton-Gillingham approach was used in the experimentation. Data were collected using the early grade reading assessment toolkit. These were administered in the two groups of respondents those were exposed to Orton-Gillingham approach from those exposed to Conventional approach (Marungko), respectively. Based on the findings, there is no significant difference in the performance between the pupils exposed to the Orton-Gillingham approach with those exposed to Conventional approach (Marungko). However, the research showed that those exposed to Orton-Gillingham Approach, twelve (50%) pupils performed as outstanding while eight (33.33%) pupils were outstanding using Marungko Approach. Thus, the Orton-Gillingham approach enhanced the pupils’ reading skills in terms of phonological awareness, appropriate spelling, retention, and better understanding. The proposed training and seminar program should be implemented to teachers for them to be able to utilize the Orton-Gillingham approach in teaching reading.

Published: November 2019

Batik is a painting or drawing on mori fabric that is made with canting tools. In Subsequent developments to speed up the process, stamp batik is used. CNC (Computer Numerical Control) based automatic stamp batik machine has been developed. This machine uses a manual batik stamper in the batik stamp (tool). The problem that arises in the use of manual chucking on this automatic stamp batik machine is the amount of time needed in the replacement and setting of the batik stamp. The design of a CNC based automatic batik machine with automatic gripper has been developed. This automatic gripper combined with the CNC based automatic stamp batik machine is programmed using a combination of G-Code for the CNC and ladder diagram for the PLC (Programmable Logic Control). Based on the design that has been applied to batik stamps produced stamping that is more consistent and has better accuracy than manual stamping. The average difference in wax thickness is 0,003 mm and has 75 seconds slower than manual stamping. This means that even though the automatic gripper provides better accuracy and precision, it sacrifices stamping times.

In 2016, the Mathematical Society of the Philippines (MSP) testified that among Filipino learners of ages 14-18, 85% experienced the dilemma on dealing with the evaluation of special angles in Trigonometry wherein 45% was from public high schools. This study aimed to determine the potential of a visual mathematical hand mnemonic tactic (VMHMT) as fast and accurate classroom mathematical mnemonic strategy in evaluating special angles in Trigonometry. A 20-item multiple choice type test with 50-minute time allotment. Reliability of the test items was also measured via Pearson’s. The test was administered three times with 7-day interval for each strategy with uniform starting time. ANOVA results showed no significant difference among the three manual strategies in terms of accuracy of answers (p=0.373) which means that the accuracy of the VMHMT is comparable with that of the other existing manual strategies. Meanwhile, significant difference was obtained in terms of speed of calculations (p=0.000) wherein the use of unit circle rendered longest time for calculations (M=21.234) while the VMHMT (M=14.70) and table of trigonometric ratios (M=14.23) appeared to be very fast. Learners find the strategy more relevant and experiential which could make a more lifelong learning.

A Nearly Incompressible Turbulence-Driven Solar Wind Model
Authors: Adhikari L , Zank G P , Zhao L.-L
Published: November 2019

We develop a 1D steady-state turbulence driven-solar wind model by coupling recently developed nearly incompressible magnetohydrodynamic turbulence transport model equations and 1D hydrodynamic solar wind equations. The dissipation of majority component quasi-2D turbulence and minority slab turbulence generated by the emergence of the “magnetic carpet” from the photosphere is responsible for heating the coronal plasma. We solve the coupled quasi-2D and slab turbulence transport equations and the solar wind equations from the base of the solar corona until 20 solar radii. We find that i) the coronal temperature increases to ~ 2.5 × 106 K near the base of the solar corona; ii) the solar wind accelerates rapidly within a few solar radii; iii) turbulence energy densities decrease and correlation lengths increase with distance; iv) balanced quasi-2D turbulence at the coronal base becomes imbalanced, and imbalanced slab turbulence becomes more imbalanced with distance, and v) the normalized quasi-2D and slab residual energy becomes positive near the coronal base, and both energies become negative with increasing distance.
Radial evolution of the properties of small-scale magnetic flux ropes in the solar wind
Authors: Hu Qiang , Chen Yu , Roux Jakobus le
Published: November 2019

Small-scale magnetic flux ropes, most with duration ≤ 1 hour at 1 AU, are found to be ubiquitous in the solar wind from in-situ spacecraft measurements. We have built an event database (fluxrope.info) for these structures identified and summarized their main physical properties. Quantitative analysis provided strong evidence in support of the view of their generation through turbulence cascade processes in space plasmas. We extend such analysis to spacecraft measurements at larger radial distances, mainly those from the Ulysses spacecraft mission. We perform comparison of relevant properties of these structures and reveal their radial evolution near the ecliptic plane. Meanwhile we also try to derive, quantitatively, the parameters important for the underlying processes including magnetic reconnection, intrinsic to turbulence cascade, in order to aid in relevant theoretical investigations. We also supplement the largely statistical analysis results with individual case studies to illustrate the process of flux rope merging and associated particle energization signatures through an observational approach. We speculate on the implications of our results and foresee future investigations that can help improve our current understanding of the origin and evolution of these small-scale magnetic flux ropes throughout the heliosphere.
Structure of the IBEX Ribbon from Distributed Sources
Authors: Schwadron N. A. , McComas D. J.
Published: November 2019

The Interstellar Boundary Explorer (IBEX) mission discovered the presence of a global structure in energetic neutral atom emissions from the outer heliosphere not predicted by any model – the IBEX “ribbon”. In the search for possible explanations, observations have pointed to a likely source from neutral atoms produced through charge-exchange with the outflowing solar wind. The secondary (neutral) solar wind then undergoes charge-exchange beyond the heliopause to produce the proton population that forms the ribbon. Here we study the plasma structure beyond the heliopause created from distributed secondary neutral atom sources. We provide a framework to analyze the IBEX ribbon taking into account distributed neutral atom sources within the local interstellar medium.
MASS – Potential Applications in Superyachts
Authors: Balls Chris
Published: November 2019

The current superyacht “Industry” continues to grow both in overall size and variety of vessel designs. Superyachts are sometimes only used privately by their owners whilst others are chartered out on a commercial basis and many operate in a combination of such modes. The largest numbers are for under 12 passengers and thus, despite having operations more akin to cruise ships, they are considered by most regulations as “Cargo Ships” those yachts carrying 13 or more passengers are considered “passenger ships”. Essentially Superyachts are just another type of ship and, as such, can easily benefit from developments in improving many ship related operations by MASS. This paper will cover a few of these areas. The views expressed in this paper are those of the author and not necessarily those of his employer.
Experiences of main risks and mitigation in autonomous transport systems
Authors: Johnsen S O , Hoem Å , Jenssen G , Moen T
Published: November 2019

This paper discusses experiences, risks and mitigation in autonomous transport systems, to improve learning and risk-based governance. This is based on literature reviews, experiences of autonomous transport systems and involvement in the regulatory process. The maturity varies between rail, road, aviation and shipping. Issues that may be transferred and adapted between modes are selected. The three research questions are: to describe major risks introduced by autonomous transport systems; how to mitigate the main risks through design and regulation; and suggest a way forward. The risk is dependent on operational domain, surrounding infrastructure, meaningful human control (including control centrals with human based interfaces), sensor ability, reliable propulsion and technology that are secure. Meaningful human control and system certification is a challenge. There is a need to gather data from incidents. In Norway autonomous shipping and road transportation are prioritized. Autonomy in rail and aviation, has not been prioritized in the same manner.

Published: November 2019

To realize intelligent obstacle avoidance and local path decisions for maritime autonomous surface ships (MASS) in uncertain environments, a navigation behavioural decision-making model based on deep reinforcement learning (DRL) algorithm improved by artificial potential field (APF) is proposed. Based on the analysis of navigation decision system and perception principle, the action space, reward function, motion search strategy and action value function are designed respectively for the purpose of steering to collision avoidance. The navigation behavioural decision-making model for MASS is improved by adding the prior information, the gravitational potential field and the obstacle repulsion potential field to update the initial action state value function and search path. Python and Pygame modules are used to build a simulation chart. Effectiveness of the algorithm is verified, with Tianjin Xingang port as a study case. The simulation results show that the APF-DRL algorithm is better than the DRL algorithm in training iteration time and piloting decision path, which improves the self-learning ability of MASS, and can meet the requirements of MASS path decision and adaptive obstacle avoidance.
A responsibility-centered approach to defining levels of automation
Authors: Myhre Bård , Hellandsvik Are , Petersen Stig
Published: November 2019

Several authors and organisations have over the last 40 years suggested various ways to describe different levels of automation. In this paper we give an introduction to some of the most relevant models and present some of the challenges faced when using them. Furthermore, we suggest a new definition for autonomy, based on responsibility instead of functionality. The paper analyses some relevant cases based on the suggested definition of autonomy, and points towards some issues that should be investigated in the maritime domain related to current definitions for autonomous ships.
