An ARIMA approach to forecasting electricity price with accuracy improvement by predicted errors

Accurate forecasting electricity price is becoming a crucial issue concerned by market participants either for developing bidding strategies or for making investment decisions. Due to the complicated factors affecting electricity prices, accurate forecasting price turns out to be very difficult and usually cannot be achieved by a single forecasting model. This paper proposes an ARIMA approach to price forecasting with accuracy improvement by predicted errors. Resides a conventional model for price forecasting, models for forecasting residual errors are also established iteratively. ARIMA models for forecasting daily average prices, based on historical data of Californian Power Market, are presented to validate the effectiveness of the proposed methodology. Results show that the method only requires easy-implemented low-order models instead of one complex model, while the accuracy of forecasting is improved significantly. The methodology can also be applied to forecasting market clearing prices and electricity loads.
IMPACTS OF RAIL TRANSIT ON PROPERTY VALUES

Introducing rail transit into a region often creates expectations about the impact of the rail project on property values. Information on the impact of rail on property values is often incomplete and limited to anecdotal evidence, leaving regions planning for rail investments without a firm basis to judge the future impact of such an investment. In addition, this lack of complete information limits the extent to which transit agencies can develop strategies to maximize positive property value impacts. This paper summarizes a comprehensive survey of recent research on the impact of rail transit and property values. The impact of twelve rail projects (including both heavy rail and light rail) throughout North America is compared to develop general conclusions about the impact of rail on property values. In general, proximity to rail is shown to have positive impacts on property values. This conclusion is based on several measures of property value such as sales prices of single-family homes, apartment rents, and median home value. This survey of recent experience also reveals that the relative impact of rail transit is affected by a number of factors. The relative increase in accessibility provided by the new transit investment is the primary factor in increasing property values. In addition, some studies show that such factors as proximity to industrial uses or to highway facilities may limit the extent to which property values are increased. These conclusions suggest a number of strategies that transit agencies can undertake to ensure maximum property value benefit for land along future rail alignments.
Seasat—A 25-year legacy of success

Thousands of scientific publications and dozens of textbooks include data from instruments derived from NASA’s Seasat. The Seasat mission was launched on June 26, 1978, on an Atlas-Agena rocket from Vandenberg Air Force Base. It was the first Earth-orbiting satellite to carry four complementary microwave experiments—the Radar Altimeter (ALT) to measure ocean surface topography by measuring spacecraft altitude above the ocean surface; the Seasat-A Satellite Scatterometer (SASS), to measure wind speed and direction over the ocean; the Scanning Multichannel Microwave Radiometer (SMMR) to measure surface wind speed, ocean surface temperature, atmospheric water vapor content, rain rate, and ice coverage; and the Synthetic Aperture Radar (SAR), to image the ocean surface, polar ice caps, and coastal regions. While originally designed for remote sensing of the Earth’s oceans, the legacy of Seasat has had a profound impact in many other areas including solid earth science, hydrology, ecology and planetary science.
Efficacy of lymph node dissection by node zones according to tumor location for esophageal squamous cell carcinoma

The extent of node dissection in esophageal cancer surgery is usually estimated by the number of resected nodes, irrespective of the area of dissection. The efficacy of lymph node dissection by area was evaluated according to the location of the primary tumor. The study group comprised the 3827 patients who underwent R0 esophagectomy with three-field lymph node dissection for squamous cell carcinoma, registered in a nationwide registry in Japan. The areas of lymph node were classified into zones according to AJCC Staging Manual. The Efficacy Index (EI) calculating the frequency and patient survival of metastases to each zone was investigated according to tumor location. The EI was high in supraclavicular and upper mediastinal zones in patients with upper esophageal tumors, highest in upper mediastinal zone followed by supraclavicular and perigastric zones in patients with middle esophageal tumors, and highest in perigastric zone followed by upper and lower mediastinal zones in patients with lower esophageal tumors. In patients with middle and lower esophageal cT1 tumors, the EIs of upper mediastinal and perigastric zones were higher than middle and lower mediastinal zones. The EIs of each zone were differed by tumor location. The extent of lymph node dissection should be estimated by the dissected zones and modified by the tumor location. Supraclavicular dissection is indispensable for patients with upper esophageal tumors, and recommended for patients with middle esophageal tumors. Upper mediastinal dissection is recommended for all patients with thoracic esophageal squamous cell carcinoma, irrespective of the location.
Methods and techniques to help quality function deployment ( QFD )

Quality function deployment (QFD) is a management tool that provides a visual connective process to help teams focus on the needs of the customers throughout the total development cycle of a product or process. It provides the means for translating customer needs into appropriate technical requirements for each stage of a product/process-development life-cycle. It helps to develop more customer-oriented, higher-quality products. While the structure provided by QFD can be significantly beneficial, it is not a simple tool to use. This article outlines how techniques such as fuzzy logic, artificial neural networks, and the Taguchi method can be combined with QFD to resolve some of its drawbacks, and proposes a synergy between QFD and the three methods and techniques reviewed. Introduction To succeed in developing thriving new products or improve on existing ones is not easy. Studies indicate that as much as somewhere between 35 per cent and 44 per cent of all products launched are considered failures (Urban, 1980). It is one thing to actually discover and measure the customers' needs and wants but, to achieve results, these findings need to be implemented, i.e. translated into company language. Many companies depend on their warranty programmes, customer complaints, and inputs from their sales staff to keep them in touch with their customers (Akao, 1990). The result is a focus on what is wrong with the existing product or service, with little or no attention on what is right or what the customer really wants. The success of a product or service largely depends on how they meet the customers' needs and expectations. Consequently, more effort is involved in getting the information necessary for determining what the customer truly wants. This tends to increase the initial planning time in the project definition phase of the development cycle, but it reduces the overall cycle time in bringing a product to market. One process-oriented design method constructed to carry out the translation process and make sure that the findings are implemented is quality function deployment (QFD). QFD is a visual connective process that helps teams focus on the needs of the customers throughout the total development cycle. It provides the means for translating customer needs into appropriate technical requirements for each stage of a product/process development life-cycle. It is well documented that the use of QFD can reduce the development time by 50 per cent, and start-up and engineering costs by 30 per cent (Clausing and Pugh, 1991).

Electronic patient records: moving from islands and bridges towards electronic health records for continuity of care.

OBJECTIVES
Electronic patient record (EPR) systems are increasingly used and have matured sufficiently so as to contribute to high quality care and efficient patient management. Our objective is to summarize current trends and major achievements in the field of EPR in the last year and to discuss their future prospects.


RESULTS
Integrating health data from a variety of sources in a comprehensive EPR is a major prerequisite for e-health and e-research. Current research continues to elaborate architectures, technologies and security concepts. To achieve semantic interoperability standards are developed on different levels, including basic data types, messages, services, architectures, terminologies, ontologies, scope and presentation of EPR content. Standards development organisations have started to harmonize their work to arrive at a consensus standard for EPR systems. Integrating the health care enterprise as a whole will optimize efficient use of resources, logistics and scheduling.


CONCLUSIONS
The past few years have seen a myriad of developments of EPR systems. However, it is still a long way, until EPR systems can flexibly fulfill all user requirements and an EHR will become broadly accepted. Semantic interoperability will be a key to successful EPR use, especially to avoid double data entries and to better integrate data recording within local workflows. The patient will become an empowered partner, not only by giving him access to his health data. All this will result in enormous quantities of data. Thus, time has come to determine how relevant data can be presented to the stakeholders adequately.
Calcium and vitamin D3 supplements in calcium and vitamin D3 sufficient early postmenopausal healthy women

Objective: To study the calcium homeostasis in healthy, calcium and vitamin D replete early postmenopausal women during oral supplementation with calcium and vitamin D3.Design: A prospective, placebo-controlled, randomised, double-single-blind, 3-week study.Setting: Outpatient clinic at Copenhagen University Hospital, Denmark.Subjects: In all, 17 started, one was excluded. Totally, 16 healthy women, 45–61 y of age (mean 57.3 y) who were at least 4 y after menopause (mean 6.7 y) completed.Interventions: All underwent three consecutive 7-day study periods. Each began with 4 days of normal diet followed by 3 days treatment of either C:one tablet of 1.250 mg calcium carbonate (ie 500 mg Ca2+ per tablet) twice daily (breakfast and dinner), or CD3:as in C but plus 400 IU vitamin D3 b.i.d., or P(only) placebo tablets b.i.d.Results: At baseline plasma 25-hydroxycholecalciferol was normal (66±22 nmol/l) and the calcium intake without supplements 850 mg/day. In group C, the 24-h urinary calcium increased by 35% (6.9±2.0 mmol), vs the placebo group P (5.1±1.6 mmol) (P<0.05). Addition of 800 IU vitamin D3 daily (CD3) did not increase calcium excretion further (6.6±2.1 mmol) but decreased plasma 1,25-(OH)2-vitamin D3 by 21% (P<0.05).Conclusions: In this carefully controlled study calcium plus vitamin D3 supplements only had minor influences of uncertain significance on the calcium balance in healthy, calcium and vitamin D sufficient early postmenopausal women.Sponsorship: Copenhagen University, Karolinska Institutet and Nycomed A/S.
Crowding out Intrinsic Motivation in the Public Sector

Employing intrinsically motivated individuals has been proposed as a means of improving public sector performance. In this article, we investigate whether intrinsic motivation affects the sorting of employees between the private and the public sectors, paying particular attention to whether extrinsic rewards crowd out intrinsic motivation. Using British longitudinal data, we find that individuals are attracted to the public sector by the intrinsic rather than the extrinsic rewards that the sector offers. We also find evidence supporting the intrinsic motivation crowding out hypothesis, in that, higher extrinsic rewards reduce the propensity of intrinsically motivated individuals to accept public sector employment. This is, however, only true for two segments of the UK public sector: the higher education sector and the National Health Service (NHS). Whilst our findings inform the literature on Public Service Motivation (PSM), they also pose the question whether lower extrinsic rewards could increase the average quality of job matches in the public sector, thus improving performance without the need for high-powered incentives.

WARP: time warping for periodicity detection

Periodicity mining is used for predicting trends in time series data. Periodicity detection is an essential process in periodicity mining to discover potential periodicity rates. Existing periodicity detection algorithms do not take into account the presence of noise, which is inevitable in almost every real-world time series data. In this paper, we tackle the problem of periodicity detection in the presence of noise. We propose a new periodicity detection algorithm that deals efficiently with all types of noise. Based on time warping, the proposed algorithm warps (extends or shrinks) the time axis at various locations to optimally remove the noise. Experimental results show that the proposed algorithm outperforms the existing periodicity detection algorithms in terms of noise resiliency.
Anesthetic considerations in organ procurement surgery: a narrative review.

PURPOSE
While a few publications specify the anesthetic implications of either brain or cardiac death, they lack detail on how to provide anesthesia during organ donation surgery. We provide a thorough description of important anesthetic considerations during organ donation surgery in patients with either brain or cardiac death.


SOURCE
A thorough literature review was undertaken to locate all relevant articles that describe systemic effects of brain and cardiac death and their anesthetic implications. We searched PubMed, Pubget, and EMBASE™ for relevant articles using the following search terms: anesthesia, management, donation cardiac death, donation brain death. In addition, we reviewed the relevant protocols at our own institution.


PRINCIPAL FINDINGS
Highly specific intraoperative management by an anesthesiologist is required during organ procurement after brain death. To manage the heart-beating brain-dead donor, the anesthesiologist must incorporate knowledge of the effects of brain death on each organ system as well as the effects of the preoperative measures that the donor required in the intensive care unit. It is also important to know which organs are going to be procured in order to establish specific goals and implement strategies (e.g., lung-protective ventilation or intraoperative glycemic control) to optimize donor outcome. During organ procurement after cardiac death, an anesthesiologist's direct involvement is particularly important for lung donors.


CONCLUSION
Anesthesiologist-guided physiological optimization of the brain-dead donor may be a factor in determining the outcome of the organ recipient. Additionally, anesthesiologists have an important role in helping to ensure that the highest quality and most appropriate care are rendered to non-heart-beating donors. This is achieved through establishing protocols in their hospitals for donation after cardiac death that maximize the number of available organs with the best chance for long-term graft viability.
A Reconfigurable Uninterruptible Power Supply System for Multiple Power Quality Applications

A novel topology of a modular per-phase uninterruptible power supply (UPS) system based on reduced-switch-count configuration is proposed in this paper. The proposed power conversion methodology offers active front-end filtering capability which ensures unity input power factor (reactive power compensation) and low input total harmonic distortion (harmonic power compensation). In addition, this UPS system provides dynamic voltage sag compensation capability, which consequently eliminates any series transformer or dc-dc boost converter that is typically used in conjunction with traditional stand-alone UPS systems. Furthermore, it has the desirable characteristics of making seamless transition from normal to backup mode during power failures and vice versa, as well as providing controlled voltage charging at the dc bus link. The proposed UPS is also impervious to load variations, which enables it to operate under nonlinear load condition. Lastly, the circuit structure is conceived from a commonly used three-leg six-switch building block, thereby making it simple and cost-effective, and offering improved power conversion efficiency as compared to a conventional line-interactive or on-line UPS schemes. A complete set of simulation and sample experimental results based on a 1-kW test prototype of the proposed UPS system are presented in this paper to demonstrate its viability and efficacy.
Comparison of intermittent pneumatic compression with manual lymphatic drainage for treatment of breast cancer-related lymphedema.

BACKGROUND
The aim of this prospective controlled study was to assess the efficacy of two different combination treatment modalities of lymphedema (LE). Manual lymphatic drainage (MLD) and compression bandage combination (complex decongestive therapy) have been compared with intermittent pneumatic compression (IPC) plus self-lymphatic drainage (SLD).


METHODS AND RESULTS
Both MLD with compression bandage (complex decongestive therapy) group (Group I, n=15) and IPC with SLD group (Group II, n=15) received treatment for LE 3 days in a week and every other day for 6 weeks. Arm circumferences were measured before and the 1st, 3rd, and 6th weeks of the treatment. EORTC-QLQ and ASES-tests were performed to assess the quality of life before and after 6 week-treatment. Patients in both groups had similar demographic and clinical characteristics. Even though both treatment modalities resulted in significant decrease in the total arm volume (12.2% decrease in Group II and 14.9% decrease in Group I) (p<0.001), no significant difference (p=0.582) was found between those two groups. Similarly, ASES scores were significantly (p=0.001) improved in both Group I and II without any significant difference between the groups. While emotional functioning, fatigue, and pain scores were significantly improved in both groups, global health status, functional and cognitive functioning scores appeared to be improved only in patients of group I.


CONCLUSIONS
Different treatment modalities consisting of MLD and compression bandage(complex decongestive therapy) or IPC and SLD appear to be effective in the treatment of LE with similar therapeutic efficacy in patients with breast cancer. However, combination modalities including IPC and SLD may be the preferred choices for their applicability at home.
Modular and High-Resolution Channel State Information and Beam Management for 5G New Radio

This article provides an overview of key features pertaining to CSI reporting and beam management for the 5G New Radio (NR) currently being standardized in 3GPP. For CSI reporting, the modular design framework and high-resolution spatial information feedback offer not only flexibility in a host of use cases and deployment scenarios, but also improved average user throughput over state-of-the-art 4G LTE. To accommodate cellular communications in the milimeter-wave regime where a combination of analog and digital beamforming is typically used at both a base station and user equipment, beam management procedures such as measurement, reporting, and recovery are introduced. The utility and joint usage of these two features are demonstrated along with some potential upgrades for the next phase of 5G NR. Introduction
Barriers to care and primary care for vulnerable children with asthma.

OBJECTIVE
I tested the hypothesis that, for vulnerable children with asthma, barriers to care (pragmatics, skills, knowledge and beliefs, expectations of care, and marginalization) affect primary care experiences, after accounting for financial, potential, and realized access to care, demographic features, and asthma severity.


METHODS
Patients, recruited primarily from urban, federally qualified health centers, were between 3 and 12 years of age and had been diagnosed as having asthma. Bilingual, bicultural interviewers administered surveys in participants' homes. Validated instruments were used to measure barriers to care (Barriers to Care Questionnaire) and primary care experiences (Parent's Perceptions of Primary Care measure).


RESULTS
Of 252 families recruited, 56.6% of parents were monolingual Spanish speakers, 73.6% of mothers had not graduated from high school, and 24.5% of children were uninsured. Asthma severity was 27% mild persistent, 40.5% moderate persistent, and 32.5% severe persistent. In bivariate analyses, better access to care (being insured and having a regular provider) was related to better primary care experiences. Consistent with the hypothesis, multivariate regression analyses showed that fewer barriers (Barriers to Care Questionnaire scores) predicted better primary care (Parent's Perceptions of Primary Care total and subscale scores), after controlling for access to care, demographic features, and asthma severity (a 1-point change in Barriers to Care Questionnaire scores was associated with a 0.59-point change in Parent's Perceptions of Primary Care total scale scores). Having a regular doctor and not having experienced foregone care were also significant predictors of Parent's Perceptions of Primary Care scores in the multivariate analysis.


CONCLUSION
For vulnerable children with asthma, barriers to care explain variance in primary care characteristics beyond that explained by access, demographic factors, and disease severity.
