Which Option Pricing Model Is the Best? HF Data for Nikkei 225 Index Options
Authors: Ryszard Kokoszczyński , Paweł Sakowski , Robert Ślepaczuk 
Published: May 2019

AbstractIn this study, we analyse the performance of option pricing models using 5-minutes transactional data for the Japanese Nikkei 225 index options. We compare 6 different option pricing models: the Black (1976) model with different assumptions about the volatility process (realized volatility with and without smoothing, historical volatility and implied volatility), the stochastic volatility model of Heston (1993) and the GARCH(1,1) model. To assess the model performance, we use median absolute percentage error based on differences between theoretical and transactional options prices. We present our results with respect to 5 classes of option moneyness, 5 classes of option time to maturity and 2 option types (calls and puts). The Black model with implied volatility (BIV) comes as the best and the GARCH(1,1) as the worst one. For both call and put options, we observe the clear relation between average pricing errors and option moneyness: high error values for deep OTM options and the best fit for deep ITM options. Pricing errors also depend on time to maturity, although this relationship depend on option moneyness. For low value options (deep OTM and OTM), we obtained lower errors for longer maturities. On the other hand, for high value options (ITM and deep ITM) pricing errors are lower for short times to maturity. We obtained similar average pricing errors for call and put options. Moreover, we do not see any advantage of much complex and time-consuming models. Additionally, we describe liquidity of the Nikkei225 option pricing market and try to compare the results we obtain here with a detailed study for Polish emerging option market (Kokoszczyński et al. 2010b).
A Balanced Dual-Band BPF with High CM Suppression and Improved Selectivity
Authors: Wei Feng , Yue Hao-Jie , Shi Xiao-Wei 
Published: May 2019

Abstract
In this paper, a balanced dual-band bandpass filter (BPF) is designed based on microstrip folded stepped impedance split ring resonators (SISRRs) and balanced microstrip/slotline transition structures. The center frequencies and the fractional bandwidths (FBWs) of the two differential-mode (DM) passbands can be tuned by changing the physical lengths of two SISRRs and the gaps between the two resonators, respectively. The balanced microstrip/slotline transition structures can achieve a wideband common-mode (CM) suppression. Moreover, the DM passbands are independent from the CM responses, which significantly simplifies the design procedure. In addition, due to 0-degree feed structure and cross coupling structure, more transmission zeros can be realized, which can improve the passbands selectivity greatly. In order to validate the design strategies, a balanced dual-band BPF centered at 2.47 GHz and 5.21 GHz was fabricated and a good agreement between the simulated and measured results is observed.
On the dimensionality of humorous conduct and associations with humor traits and behaviors
Authors: Ruch Willibald , Heintz Sonja 
Published: May 2019

AbstractThe aim of the present study is to explore higher-order dimensions of humorous conduct derived from 100 non-redundant and comprehensive statements. These dimensions are validated in self- and other-reports and their criterion validity is assessed by relating them to other humor concepts (temperamental basis of the sense of humor, attitudes towards laughter and being laughed at, humor appreciation and creation). Four broad dimensions (mean-spirited/earthy, entertaining, inept, and reflective/benign) were supported in self- and other-reports, and two narrower dimensions (laughter and canned) were found in self-reports. These dimensions covered affective, cognitive, and dysfunctional aspects of humorous conduct and spanned across humorous temperament, attitudes towards laughter and being laughed at as well as humor appreciation and creation. These six dimensions can serve as a reference framework and higher-order categories to which humor scales could be assigned. Future studies need to test the comprehensiveness of these dimensions and conduct further validation studies.

) in India, corresponding to the new Moon and full Moon days which are associated with abnormality in the eastward Equatorial Electrojet (EEJ) currents. It has been well established that even during certain geomagnetic quiet days, the EEJ current direction is reversed, resulting in a westward electrojet current called Counter Electrojet (CEJ) which is more prominent around the new Moon and full Moon days, favored by Sun–Moon–Earth alignments and lunar orbital characteristics. The Global Positioning System (GPS) derived TEC at Bangalore is investigated for full Moon and new Moon and their adjacent days during the period 2008–2015. The presence of CEJ during these days suggests the foremost role of driving EEJ current over the equator in the alterations of spatiotemporal distributions of TEC over the low latitude region. The deviations in quiet time TEC during new Moon and full Moon days are quantified in this study that may give a thrust towards modeling of lunar tidal effects in the flipped ionospheric parameter over the Indian region. The study would also support analysis of future solar eclipse effects on ionosphere those involve additional photoionization production/recombination processes corresponding to the passage of lunar shadow and cooling effects. Moreover, the results underpin modeling and mitigation of ionospheric error in the satellite-based positioning, navigation, and communication applications.
Polynomial expressions of p-ary auction functions
Authors: Kaji Shizuo , Maeno Toshiaki , Nuida Koji , Numata Yasuhide 
Published: May 2019

Abstract
One of the common ways to design secure multi-party computation is twofold:
to realize secure fundamental operations and to decompose a target function to be securely computed into them.
In the setting of fully homomorphic encryption, as well as some kinds of secret sharing,
the fundamental operations are additions and multiplications in the base field such as the field

𝔽
2

{\mathbb{F}_{2}}

with two elements.
Then the second decomposition part, which we study in this paper, is (in theory) equivalent to expressing the target function as a polynomial.
It is known that any function over the finite prime field

𝔽
p

{\mathbb{F}_{p}}

has a unique polynomial expression of degree at most

p

{p-1}

with respect to each input variable;
however, there has been little study done concerning such minimal-degree polynomial expressions for practical functions.
This paper aims at triggering intensive studies on this subject,
by focusing on polynomial expressions of some auction-related functions such as the maximum/minimum and the index of the maximum/minimum value among input values.
Automated tableau generation using SPOT (Syntax Prosody in Optimality Theory)
Authors: Bellik Jennifer , Kalivoda Nick 
Published: May 2019

AbstractMuch recent work on the syntax-prosody interface has been based in Optimality Theory. The typical analysis explicitly considers only a small number of candidates that could reasonably be expected to be optimal under some ranking, often without an explicit definition of GEN. Manually generating all the possible candidates, however, is prohibitively time-consuming for most input structures – the Too Many Candidates Problem. Existing software for OT uses regular expressions for automated generation and evaluation of candidates. However, regular expressions are too low in the Chomsky Hierarchy of language types to represent trees of arbitrary size, which are needed for syntax-prosody work. This paper presents a new computational tool for research in this area: Syntax-Prosody in Optimality Theory (SPOT). For a given input, SPOT generates all prosodic parses under certain assumptions about GEN, and evaluates them against all constraints in CON. This allows for in-depth comparison of the typological predictions made by different theories of GEN and CON at the syntax-prosody interface.
Effects of average and specific context probability on reduction of function wordsBEandHAVE
Authors: Barth Danielle 
Published: May 2019

AbstractIn a study of word shortening ofHAVEand contraction ofBE, it is found that both high transitional probability and high average context probability (low informativity) result in reduction. Previous studies have found this effect for content words and this study extend the findings to function words. Average context probability is by construction type, showing that words are shorter in constructions with high average predictability, namely in perfect constructions forHAVEand in future and progressive constructions forBE. These findings show that in cases of grammaticalization, it is not an increase in frequency that results in reduction, but a decrease in informativity.

Willingness to Pay for Energy Efficient Refrigerating Appliances in Accra, Ghana: A Choice Experiment Approach
Authors: Asinyaka Michael 
Published: May 2019

AbstractThe use of energy efficient refrigerating appliances in the domestic sector holds promise for savings on energy, CO2emissions and CFC leakages, and more so for developing countries than for developed countries. However, the low saliency of energy efficiency and monetary savings impedes the uptake of energy efficient appliances by end-use consumers and suppliers of residential appliances. Moreover, there is the lack of information on how consumers value different refrigerating appliances and appliance features as well as how much they are willing to pay for same. Applying a choice experiment approach, this paper valued consumers’ preferences for energy efficient refrigerating appliances and found that willingness to pay (WTP) is significant and positive at GH¢3,078.12 ($690). However, evidence of the influence of socio-demographics on WTP and preferences is inconclusive.
Does It Pay to Be Active on Many Foreign Markets? Profitability in German Multi-Market Exporters and Importers from Manufacturing Industries
Authors: Wagner Joachim 
Published: May 2019

AbstractThis paper provides the first empirical evidence on the link between the number of foreign markets (where a market is defined as the combination of one traded good and one country traded with) a firm is active on and its profitability. We find that in German manufacturing industries the profitability of a firm is neither positively nor negatively related to the number of foreign markets. The extra costs associated with being active on more foreign markets tend to be balanced by the extra benefits. Therefore, we have evidence that it does not pay to be active on many foreign markets.
Tourism development in transition economies of the western Balkans
Authors: Lehmann Tine , Gronau Werner 
Published: May 2019

AbstractTourism development in transition economies is characterized by hazards and incomplete setups. Tourists encounter lacking accommodation standard, full trash bins, insufficient health care and security infrastructure. Hence, tourism development actors in transition economies are often criticized for the incomplete touristic product. In this article we will have a more detailed look on this criticism and analyse the background of this discussion. We follow the criticism and analyse the given institutional constrains that influence tourism development in transition economies. We therefore question, what are the effects of these institutional constrains on tourism development in transition economies. We follow a qualitative approach with a single case study from a cross-border hiking trail in southeast Europe. Our data is based on secondary data, participant observer material and interviews with local actors. We demonstrate that transition economies face institutional voids, while performing well, when it comes to increasing tourism numbers. Therefore, the contribution aims on providing possible explanation on the obvious contradiction of a partly incomplete, but successful tourism product. The authors question the importance of classical quality criteria in case of the specific tourism product and the specific clientele while stressing the dimensions of authenticity, credibility and homogeneity of the given tourism setting.
Mechanical Properties of Multiwalled Carbon Nanotube–Reinforced Cement Composites
Authors: Sharma Sumit , Dubey Krishan Mohan , Setia Prince 
Published: May 2019

Abstract
Cement is a great resource for the construction of buildings, dams, bridges, etc. because of its high compressive strength, but it has low tensile and flexural strength. Thus, to improve its properties, cement has been reinforced with carbon nanotubes (CNTs). Three groups of specimens of cement composites containing multiwalled CNTs (MWCNTs) with different concentrations of MWCNTs (0, 0.2, and 0.3 % by weight of cement) were prepared. From the results, it was observed that the 0.3 wt. % MWCNT-cement composites had higher flexural strength compared to the 0.2 wt. % MWCNT-cement composites at 21 days, but the reverse was the case at the age of 14 days. The 0.2 wt. % MWCNT-cement composites had greater strain-to-failure than the 0.3 % MWCNT-cement composites at 14 as well as 21 days.

Published: May 2019

Objectives
Inoperable or metastatic paragangliomas (PGLs) and malignant pheochromocytomas (PCCs) are rare tumours with limited options for systemic treatment. Aim of this study was to assess the safety and efficacy of the radiolabelled somatostatin analogue (177LutetiumDOTA0-Tyr3)octreotate (177Lu-DOTATATE) for the treatment of PGLs and PCCs.

Methods
Patients with histologically proven inoperable or malignant PGLs and PCCs treated with 177Lu-DOTATATE at our centre were retrospectively analysed. Patients were treated with up to four cycles of 177Lu-DOTATATE with an intended dose of 7.4 Gb per cycle. Response was assessed with use of RECIST 1.1.

Results
Thirty patients were included: 17 with parasympathetic, 10 with sympathetic PGLs and 3 with PCCs. Grade 3/4 subacute haematotoxicity occurred in 6 (20%) of patients. A reversible subacute adverse event due to cardiac failure following possible catecholamine release occurred in two patients. Best tumour response was partial response in 7 (23%) and stable disease in 20 (67%), whereas 3 (10%) patients had progressive disease. In 20 patients with baseline disease progression, tumour control was observed in 17 (85%); the median progression-free survival was 91 months in patients with parasympathetic PGLs, 13 months in patients with sympathetic PGLs and 10 months in patients with metastatic PCCs.

Conclusion
This study suggests that PRRT with 177Lu-DOTATATE is a safe and effective treatment option for patients with inoperable or malignant PGL and PCC.
Pulmonary Function Testing and Outcomes after Left Ventricular Assist Device Implantation
Authors: Raheja Suraj , Nemeh Hassan , Williams Celeste , Tita Cristina , Selektor Yelena , Chamogeorgiakis Themistokles , Lanfear David 
Published: May 2019

Background: Pulmonary function testing (PFT) is often done during workup prior to left ventricular assist devices (LVAD), but its utility for predicting outcomes and changes in pulmonary function post-LVAD is not well established. We assessed the association of baseline PFT metrics with outcomes after LVAD, and quantified the changes in PFTs post-LVAD.
Methods and results: A retrospective study of 178 patients receiving continuous flow LVADs was conducted. A total of 129 subjects had baseline PFT data and 54 of these had repeat tests after LVAD. We collected PFT data (FEV1, FVC, FEV1/FVC ratios, and DLCO) at baseline and post-LVAD, and tested the association with survival, right heart failure, quality of life (Kansas City Cardiomyopathy Questionnaire [KCCQ]) and functional capacity (six-minute walking distance [6MWD]). Proportional hazards and linear regressions determined relationships between baseline PFT data and survival time and functional outcomes, respectively. Paired t-tests compared pre- and post- LVAD PFT variables. There was no association of baseline PFT parameters with survival time post-LVAD (all P > .2), nor the incidence of perioperative RV failure (all P > .15). There were no significant associations of the baseline PFT metrics with the change in KCCQ or 6MWD. There were statistically significant declines in FEV1, FEV1/FVC ratio, and DLCO after LVAD (P < .05).
Conclusion: In this single center study, there was no relationship between baseline PFTs and post-LVAD outcomes, and PFT parameters often worsened after LVAD. Further studies are needed to determine whether PFTs are useful in this setting, and what, if any, impact LVAD therapy has on pulmonary function.

Management of severe haemophilia A during surgery: case report
Authors: Cordial Ma Hazel 
Published: May 2019

Abstract
We describe the case of a patient with severe haemophilia A and significant comorbidities who underwent surgery to remove a large intra-abdominal haematoma first diagnosed 12 years previously. The haemophilia team was instrumental in coordinating care, building a strong rapport with surgical and other medical teams to manage bleeding risk with continuous infusion of factor VIII (FVIII). Medical teams adjusted their working hours according to clinical need. Haemophilia nurses were available to offer support at all times, and developed management procedures and educated staff on haemophilia and its treatment. Perioperative complications included a thrombus occluding the right internal jugular vein, infection and paraesthesia. However, surgery was effective and the patient was pleased with the overall outcome. Haemophilia nurses established strong and rewarding relationships with other teams that will enhance the delivery of care in the future.
