A mean–variance acreage model

ABSTRACT We study a mean–variance acreage model, , where p is price at harvest time and E and V are the expectation and variance operators conditional on information known at planting time. Under the assumption that where yield y is random and unknown at planting time, we will investigate the existence, uniqueness, and convergence of this fixed point problem as well as the coherence of the mean–variance model. As is well known, Newton's method can not guarantee its convergence unless the initial approximation is sufficiently close to a true solution. In theory, the more variables/randomness one has, the harder it is to find a good initial guess. Specifically we focus on the case when the inverse demand function is implicitly defined. We will solve the random nonlinear equations by Newton's method and investigate the optimal and robust way to choose random initial values for Newton's method. The robust initial value will allow us to study how the price support program will affect consumer prices, farm prices, and government expenditures as well as their variabilities. Hopefully solving nonlinear random equations will shed some light on the choice of initial values for Newton's method.

Effect of aluminum and fluoride on R2R3-MYB transcription factor characterization and expression in Camellia sinensis

Tea plant (Camellia sinensis) is a typical plant that accumulates abundant aluminum (Al) and fluoride (F). Al and F play vital roles in the growth and development in tea plant. MYB (myeloblastosis) is one of the largest transcription factor families in plant, which plays an important role in the stress responses. As the largest and multifunctional subfamily of MYB, R2R3-MYB subfamily participates in multiple abiotic stresses in plant. However, there are few studies about R2R3-MYB in tea plant, especially in the accumulation of Al and F during its growth. Here, we identified 43 CsMYB genes from the transcriptome database of tea plant and analyzed the relative expression in Al and F treatments. According to the Arabidopsis thaliana classification, 43 CsMYB genes are divided into 18 subgroups via phylogenetic tree analysis. All 43 CsMYB proteins have the typical R2R3-MYB domain by MEME prediction. Moreover, 9 CsMYB genes (CsMYB11, CsMYB17, CsMYB29, CsMYB38 to CsMYB43) that related to abiotic stress were selected from 43 CsMYB genes for a further study, and the relative expressions showed that they are tissue-specifically expressed. In addition, the results of different concentrations of Al treatments showed that CsMYB11, -17, -29, -38 and -41 are stimulated by Al treatment. The results of different concentrations of F treatments showed that the CsMYB11, -17, -38, -39, -40, -41, -42 and -43 participate in F accumulation of C. sinensis roots. Our research establishes a solid foundation for further investigation into the molecular functions of R2R3-MYB transcription factors in C. sinensis.
Resectable locally advanced gastric adenocarcinoma: interim analysis

In locally advanced gastric cancer, it is crucial to recognize tumor T staging, lymph node status, the plane with adjacent structures and the presence of peritoneal carcinomatosis before initiation of perioperative chemotherapy. Contrast-enhanced CT (CECT) scan helps to evaluate T stage, nodal status, planes with adjacent structures distant visceral metastasis, ascites, large peritoneal and omental nodules. However small peritoneal nodules are difficult to pick up on a CT scan. Staging laparoscopy allows us to directly see the peritoneal and visceral surface, to take ascitic or peritoneal washing fluid cytology and biopsy of suspected lesions. It has been estimated that occult M1 is detected by staging laparoscopy in about 30-40% of patients.
Computing the Assembly Guidance for Maximizing Product Quality in the Virtual Assembly

Assembly is the final process of manufacturing, and a good assembly plan reduces the effect of the tolerance generated in the early stages by the tolerance elimination. In the current assembly lines, the assemblers pick up the workpieces and install them together by the assembly instructions. When the workpieces are oversize or undersize, the product can not be installed correctly. Therefore, the assembler considers the secondary processing to fix the tolerance and then installs them together again. The product could be installed, but the product quality may be reduced by the secondary process. So, we formulate the assembly process as a combinatorial optimization problem, named by the dimensional chain assembly (DCA) problem. Given some workpieces with the corresponding actual size, computing the assembly guidance is the goal of the DCA problem, and the product quality is applied to represent the solution quality. The assemblers follow the assembly guidance to install the products. We firstly prove that the DCA problem is NP-complete and collect the requirements of solving the DCA problem from the implementation perspective: the sustainability, the minimization of computation time, and the guarantee of product quality. We consider solution refinement and the solution property inheritance of the single-solution evolution approach to discover and refine the quality of the assembly guidance. Based on the above strategies, we propose the assembly guidance optimizer (AGO) based on the simulated annealing algorithm to compute the assembly guidance. From the simulation results, the AGO reaches all requirements of the DCA problem. The variance of the computation time and the solution quality is related to the problem scale linearly, so the computation time and the solution quality can be estimated by the problem scale. Moreover, increasing the search breadth is unnecessary for improving the solution quality. In summary, the proposed AGO satisfies with the necessaries of the sustainability, the minimization of computation time, and the guarantee of product quality for the requirements of the DCA, and it can be considered in the real-world applications.
Frequency- and area-specific entrainment of intrinsic cortical oscillations by repetitive transcranial magnetic stimulation

Neural oscillations are ubiquitous throughout the cortex, but the frequency of oscillations differs from area to area. To elucidate the mechanistic architectures establishing various rhythmic activities, we tested whether spontaneous neural oscillations in different cortical modules can be entrained by direct perturbation with distinct frequencies of transcranial magnetic stimulation (TMS). While recording the electroencephalogram (EEG), we applied single-pulse TMS (sTMS) and repetitive TMS (rTMS) at 5, 11, and 23 Hz to motor or visual cortex. To assess entrainment, defined as phase locking of intrinsic oscillations to periodic external force , we examined local and global modulation of the phase-locking factor (PLF). sTMS triggered transient phase locking in a wide frequency band with distinct PLF peaks at 21 Hz in the motor cortex and 8 Hz in the visual cortex. With TMS pulse trains of 11 Hz over visual cortex and 23 Hz over motor cortex, phase locking was progressively enhanced at the stimulation frequency and lasted for a few cycles after the stimulation terminated. Moreover, such local entrainment propagated to other cortical regions, suggesting that rTMS entrained intrinsic neural oscillations locally and globally via network nodes. Because the entrainment was frequency-specific for each target site, these frequencies may correspond to the natural frequency of each cortical module and of the global networks. rTMS enables direct manipulation of the brain and is thus useful for investigating the causal roles of synchronous neural oscillations and synchrony in brain functions, and for the treatment of clinical symptoms associated with impaired oscillations and synchrony. Significance Statement We provide the first evidence for area- and frequency-specific entrainment by frequency-tuned repetitive transcranial magnetic stimulation (rTMS), and the propagation of this entrainment to other areas. Our results indicate that rTMS at the natural frequency of each cortical system is particularly effective for entraining oscillatory phase. Moreover, local entrainment led to global entrainment in functionally coupled areas. The ability to control brain rhythms in the intact human brain is highly beneficial for studying the causal roles of rhythmic activity in brain function. Moreover, this modulatory technique has the potential to treat patients with impaired rhythmic networks in disorders such as schizophrenia and stroke.
Microwave System for Input-Output Radiation of the Two-Cascade Gyro-TWT at 3-mm Wavelength

The paper presents the results of calculations of the output microwave systems of broadband gyro-TWTs of the 3 mm wavelength range united in the common cascade. To achieve a high output power (300 kW), it is proposed to use a cascade of two gyro-TWTs, the first of which has a relatively high gain (40–60 dB), and the second has a high output power with a moderate gain (15–20 dB). The radiation output of the first stage is performed along the axis of the tube through the waveguide depressed collector. The microwave system of the second stage has a transverse radiation input-output through a single barrier window with the signal separation by their polarizations. The transformation of wave fields is carried out by waveguide converters and a system of external quasi-optical mirrors. The calculated efficiency of the output system in the frequency range 90–100 GHz exceeds 95%. The paper compares the methods and approaches used to model the microwave systems.
Epidemiological Assessment of Urinary Schistosomiasis among School-aged Children in Selected Local Government Areas in Gwandu Emirate of Kebbi State, Nigeria

Urinary schistosomiasis remains a public health problem in the tropics. The study examines the prevalence of urinary schistosomiasis among school-aged children in Bunza, Koko and Aliero Local Government Areas (LGAs) in Gwandu Emirate of Kebbi State, Nigeria. Four hundred and seventyfour (474) urine samples were examined for ova of Schistosoma haematobium using sedimentation technique and chemical reagent strip for haematobium detection. The overall prevalence of S. haematobium recorded was 126 (26.58%). The distribution of infection by location revealed that Bunza had highest infection (35.1%), followed by Koko (28.00%) and Aliero (17.1%). Bunza showed Odd ratio (OR) of 2.02 and 95% CI (1.33 – 3.08) with statistical significance of P < 0.0014 Original Research Article Idayat et al.; JALSI, 23(5): 36-45, 2020; Article no.JALSI. 58373 37 which indicates that location plays a significant factor in prevalence of infection. The prevalence of infection in relation to gender showed that males had the highest percentage 37.13%, Chi-square revealed that there was difference between the males and female infection rate (P < 0.0001) while 16.03% was observed among the females. The age bracket 9 – 12 years old 47.05% were the most affected with the infection, while children 5 – 8 years bracket with 15.08% had the least infection rate. Chi-square shows that there was difference between the ages and infection rate of (P<0.0001). Blood in urine (haematuria) was significantly associated with infection rate. Watercontact activities recorded revealed that there was association between water contact and infection rate (P-value < 0.0001). With the high prevalence of infection in the study areas, there should be a concerted effort by stakeholders in the state, not just to establish a comprehensive data on the prevalence of the infection, but also to take decisive action in its control.
Measuring the effectiveness of English Medium Instruction Shipping courses

Purpose Shipping courses contain much technical and specialist knowledge and present particular challenges for English medium instruction (EMI). This paper aims to investigate both student perceptions of the importance and satisfaction level of EMI in shipping courses in higher education in Taiwan and the perceptions of expert stakeholders through qualitative interviews. Design/methodology/approach Importance-performance analysis (IPA) is used to gather data on participants’ perceptions of what is (un)important and (un)satisfactory. Based on past studies, four dimensions with 20 items were developed and 121 effective questionnaires were collected. Further, qualitative interviews with expert stakeholders (n = 9) are undertaken to gather data to contextualize and complement the quantitative student data. Findings Findings show students attributed high importance but low satisfaction to items such as course learning objectives and students’ English level, and low importance and high satisfaction to items such as electronic teaching platform and relevance of subject to practice. Factor analysis and cluster analysis were used to divide samples into three groups. Qualitative interview results confirm many of the quantitative findings but also show where some quantitative findings require more attention or investment when delivering EMI programmes. Research limitations/implications Questionnaire samples focus on university students. Other related field samples (e.g. EMI teachers, shipping teachers, English teachers, etc.) could be surveyed and compared in future studies. Qualitative interviews could also be expanded to other stakeholders such as government policymakers. Practical implications The findings of IPA in the shipping courses and the qualitative interviews can be used for both teaching design and implementation in related courses by university lecturers and other stakeholders (e.g. policy and decision-makers). Such approaches can enhance students’ learning motivation and teaching performance. Social implications This paper provides important guidance and diagnosis for how to introduce English teaching in shipping courses. Related courses can be further applied in higher education to popularize and promote EMI teaching in shipping and related fields. Originality/value EMI has seldom been studied in the context of shipping courses in the past. This paper adopts IPA method and qualitative interviews to complement previous studies and address gaps in recent research. It is expected that the research findings could be adapted and applied in other fields.
Contrasting effects of space and environment on functional and phylogenetic dissimilarity in a tropical forest

Aims The evolutionary history and functional traits of species can illuminate ecological processes supporting coexistence in diverse forest communities. However, little has been done in decoupling the relative importance of these mechanisms on the turnover of phylogenetic and functional characteristics across life stages and spatial scales. Therefore, this study aims to estimate the contribution of environment and dispersal on the turnover of phylogenetic and functional diversity across life stages and spatial scales, in order to build a coherent picture of the processes responsible for species coexistence. Methods We conducted the study in Xishuangbanna Forest Dynamics Plot in Yunnan Province, southwest China. We used four different spatial point process models to estimate the relative importance of dispersal limitation and environmental filtering. The functional traits and phylogenetic relationships of all individual trees were incorporated in the analyses to generate measures of dissimilarity in terms of pairwise and nearest-neighbor phylogenetic and functional characteristics across life stages and spatial scales. Important Findings We found non-random patterns of phylogenetic and functional turnover across life stages and spatial scales. Environmental filtering structured pairwise phylogenetic and functional beta diversity across spatial scales, while dispersal limitation alone, and in combination with environment filtering, shaped nearest neighbor phylogenetic and functional beta diversity. The relative importance of dispersal limitation and environmental filtering appeared to change with life stage but not with spatial scale. Our findings suggest that phylogenetic and functional beta diversity help to reveal the ecological processes responsible for evolutionary and functional assembly and highlight the importance of using a range of different metrics to gain full insights into these processes.
Relative Efficiency of Two Models of Ugglan Special Live-Traps for Capturing Small Rodents in Boreo-Nemoral Forest

Live trapping is an invaluable and commonly used technique for studying small mammal populations. There are several types of commercially available live-traps, but some models have been shown to differ in terms of species-specific efficiency. Such differences could lead to biased results, and knowledge of such bias is important when comparing results of different studies. The Ugglan Special live-trap is one commonly used type, and it is available in several different models. I studied performance of the two most common models (No. 1 and No. 2) to find out whether they differ in terms of overall efficiency and body-mass-dependent efficiency, when trapping small rodents. I used 48 traps of each model in boreo-nemoral forest during three years, which amounted to 3456 trap nights, during which 268 bank voles (Myodes glareolus) (26%) and wood mice (Apodemus sylvaticus) (74%) were captured. There was no difference in body mass between the animals captured by the two trap models. Model No. 2, however, was more efficient in capturing bank voles, but not wood mice, than model No. 1. This difference may have been caused by the difference in the entrance design. This species-specific dissimilarity in trap efficiency should be taken into account when using Ugglan Special live-traps in ecological research relying on mark–recapture methods. Additional studies are needed to see if other species of small mammals are affected in similar ways and if the differences are consistent among habitat types.
Metamizole (dipyrone) – cytotoxic and antiproliferative effects on HeLa, HT-29 and MCF-7 cancer cell lines

Abstract Cancer pain treatment is a big challenge for healthcare providers and patients as well. The wide range of non-steroidal anti-inflammatory drugs (NSAIDs) used as painkillers in cancer patients, requires in-depth characterization of their effect on the disease process. The effects of NSAIDs have been widely studied over the last decades as preventive drugs in some oncological diseases. Metamizole is an NSAID belonging to the non-narcotic analgesics group and is highly recommended in oncology either alone or in combinations with opioid analgesics. There is a dearth of information regarding the cytotoxicity profile of metamizole and hence the present study evaluated the potential anticancer activity of metamizole in some permanent human tumour cell lines: HeLa, human cervical cancer cells; HT-29, a human colorectal adenocarcinoma cell line; and МСF-7, human breast adenocarcinoma cells. The studied tumour cells were sensitive to metamizole at doses higher than 25 μg/mL. Metamizole induced a statistically significant decrease in the viability of HeLa, HT-29 and MCF-7 cells in in vitro tests as measured by the MTT assay; the highest effect was observed at the 48th hour of the treatment. Metamizole could induce cell death by apoptosis. Metamizole also suppressed the migration of the three tumour cell lines. This was most clearly pronounced in HeLa cells. The results obtained indicate that metamizole is a suitable choice for the treatment of cancer pain and has prospects for further in-depth studies.
Risk of Impingement on Polyethylene Liner of Total Hip Arthroplasty Prosthesis during Muslim Prayer (Salat) Activity

Total hip arthroplasty (THA) is one of the most successful orthopedic surgical procedures. Impingement believed to be the most common mechanism of dislocation after THA. Salat consist of several repeated physical movements which require several extreme hip joint movements. The potential impingement positions during salat activity have been revealed by the previous computer simulation study, some evidences of impingement from retrieved polyethylene liner also have been revealed from our recent preliminary data. Although further study is still needed in this field, we may give special advice to modify some movement for Muslim patient who receive THA when performing Salat activity.
Migrants during Halftime: the framing of Hungarian political news during the FIFA World Cup

ABSTRACT This study examines the one-minute news blocks aired during the 2018 FIFA World Cup games on Hungarian public television. The analysed short segments were used to direct viewer attention to a narrow range of migration-related news items and implemented reporting on the refugees as a framing device for domestic and international political conflicts. The topics provided a context for world events that overwhelmingly benefited the government’s narrative on the situation. This effect was achieved by a synergy of episodic and thematic frames that were used to explain the behaviour of political actors, substantially simplifying them to pro- and anti-immigration parties.
