Coordinated multiple point reception scheme for the uplink of LTE-advanced system

LTE-Advanced system based on orthogonal frequency division multiplexing (OFDM) can eliminate intra-cell interference since data are carried on the orthogonal subcarries; however, it can not mitigate inter-cell interference (ICI) which affects the performance severely. Therefore, coordinated multiple point (CoMP) reception scheme was proposed to reduce ICI and improve the cell capacity for the uplink of LTE-Advanced system. The basic idea of CoMP is to extend the conventional system to a multi-cell MIMO structure by sharing necessary information and received signals across multiple evolved Node Bs (eNB). This paper focus on evaluation of the CoMP scheme in which joint detection with minimum-mean-square-error (MMSE) algorithm is configured at the eNB side to cancel the ICI from other users. To guarantee fairness of the cell-edge users, proportional fair (PF) scheduling method is adopted. Simulation results for uplink show that the CoMP scheme can significantly improve the average cell throughput and reduce ICI for the cell-edge users.
Financial Factors Influencing the Quality of Corporate Social Responsibility and Environmental Management Disclosure: A Quantile Regression Approach

This paper revisits the influence of companies’ financial factors on the extent of corporate environmental sustainability reporting (CESR) in an impressive sample of 3931 companies operating in 51 industries and 59 countries. A CESR composite index is constructed for each company that focuses on the G3 core environmental indicators from the Global Reporting Initiative because they are material for most organizations. In a methodological innovation, this study employs a quantile regression that unfolds certain interesting effects of financial drivers on the intensity of CESR that have not previously been revealed. Considering a combination of the main underlying theories of corporate sustainability reporting – legitimacy theory, agency theory, political costs theory, and signal theory – offers a better understanding of the complex structure of the dependencies found among factors such as company size, leverage, return on assets, research and development spending, market return and market capitalization, and commitment to environmental reporting.

The DEAD box protein Dhh1 stimulates the decapping enzyme Dcp1

An important control step in the regulation of cytoplasmic mRNA turnover is the removal of the m7G cap structure at the 5′ end of the message. Here, we describe the functional characterization of Dhh1, a highly conserved member of the family of DEAD box‐containing proteins, as a regulator of mRNA decapping in Saccharomyces cerevisiae. Dhh1 is a cytoplasmic protein and is shown to be in a complex with the mRNA degradation factor Pat1/Mtr1 and with the 5′–3′ exoribonuclease Xrn1. Dhh1 specifically affects mRNA turnover in the deadenylation‐dependent decay pathway, but does not act on the degradation of nonsense‐containing mRNAs. Cells that lack dhh1 accumulate degradation intermediates that have lost their poly(A) tail but contain an intact 5′ cap structure, suggesting that Dhh1 is required for efficient decapping in vivo. Furthermore, recombinant Dhh1 is able to stimulate the activity of the purified decapping enzyme Dcp1 in an in vitro decapping assay. We propose that the DEAD box protein Dhh1 regulates the access of the decapping enzyme to the m7G cap by modulating the structure at the 5′ end of mRNAs.
An Open Corpus for Named Entity Recognition in Historic Newspapers

The availability of openly available textual datasets (“corpora”) with highly accurate manual annotations (“gold standard”) of named entities (e.g. persons, locations, organizations, etc.) is crucial in the training and evaluation of named entity recognition systems. Currently there are only few such datasets available on the web, and even less for texts containing historical spelling variation. The production and subsequent release into the public domain of four such datasets with 100 pages each for the languages Dutch, French, German (including Austrian) as part of the Europeana Newspapers project is expected to contribute to the further development and improvement of named entity recognition systems with a focus on historical content. This paper describes how these datasets were produced, what challenges were encountered in their creation and informs about their final quality and availability.
Detection of malignant tumors in end-stage cirrhotic livers: efficacy of sonography as a screening technique.

OBJECTIVE Patients with hepatic cirrhosis are at an increased risk of developing primary malignant tumors of the liver. If these tumors are discovered early, current therapies may be curative. We conducted a prospective study to assess the accuracy of sonographic screening for the detection of malignant tumors in cirrhotic livers as determined by correlation with resected whole livers. SUBJECTS AND METHODS A total of 200 prospectively interpreted preoperative sonograms from 200 patients with cirrhosis who underwent hepatic transplantation were correlated with specimens of freshly resected whole livers. The results were analyzed to determine the sensitivity and specificity of sonography in identifying patients with malignant tumors and detecting individual tumors in each patient. RESULTS Pathologic examination showed 80 malignant lesions in 34 patients (28 with hepatocellular carcinoma, three with cholangiocarcinoma, two with metastases, and one with non-Hodgkin's lymphoma) and three hemangiomas in two patients. Sonography correctly showed malignant tumors in 17 of the 34 patients, for a sensitivity of 50%. Sonograms were false-positive for malignant tumors in three patients, two of whom had a total of three hemangiomas. Sonography correctly showed 36 of the 80 malignant lesions, for a lesion sensitivity of 45% and specificity of 98%. Of the 44 missed lesions, 24 were 1 cm or less, 12 were between 1 and 3 cm, and eight were more than 3 cm in diameter. CONCLUSION Our results show that sonography is highly insensitive in the detection of malignant lesions in end-stage cirrhotic livers and thus is not a reliable screening technique. However, because of sonography's very high specificity, any sonographically identified lesion in a cirrhotic liver should be considered malignant until proved otherwise.
Marketing and Reputation within Professional Service Firms

This chapter reviews the research on marketing and reputation relevant to professional service firms (PSFs). Although there has been relatively little research to date, we organise the material by problematising the issue of marketing within PSFs before introducing reputation and using a conceptual model of reputation which explores its antecedents and consequences within PSFs. In reviewing the extant literature, we explore a series of problems inherent within the application of marketing principles and practice to PSFs as well as hint at solutions and identify a future research agenda for marketing and reputation.
Volunteer Web Site Effectiveness: Attracting Volunteers via the Web

Volunteer programs are shifting towards the use of web sites to recruit volunteers. Using previously recommended practices for web site management, the authors analyzed 93 web sites of volunteer-based animal welfare organizations regarding 14 best practices in web design and management. On average, the organizations used nine of the 14 best practices. The most commonly used practices included (1) providing a link to the volunteer program web page and (2) providing an organizational mission statement. The least commonly used practices included (1) providing information for future orientation sessions and (2) providing a volunteer program mission statement. Analyses further indicated that the number of best practices used is related to the number of volunteers at each program even after controlling for the overall size of the organization or the availability of resources (i.e., total revenue). Implications for volunteer resource managers are discussed.
A mean-field approach to some Internet-like random networks

A conditionally Poissonian power-law random graph with infinite degree variance is considered as a random network model. A method for elegant analytical computation of accurate approximations for various network characteristics is introduced, based on slight redefinition of the model in terms of non-homogeneous Poisson point processes and on the replacement of certain random variables by their expectations. The applications include characterization of the ‘top clique’ around the node of highest capacity, density of nodes falling outside of the giant component of the random graph, availability of disjoint paths and the distribution of traffic in the network, assuming a traffic matrix following a gravity rule.
Combined Diffuse Optical Tomography (DOT) and MRI System for Cancer Imaging in Small Animals

Recently, there has been a great amount of interest in developing multi-modality imaging techniques for oncologic research and clinical studies with the aim of obtaining complementary information and, thus, improving the detection and characterization of tumors. In this present work, the details of a combined MR-diffuse optical imaging system for dual-modality imaging of small animals are given. As a part of this effort, a multi-spectral frequency domain diffuse optical tomography system is integrated with an MRI system. Here, a network analyzer provides the rf modulation signal for the laser diodes and measures the amplitude and the phase of the detected signals. Photomultiplier tubes are utilized to measure low-level signals. The integration of this optical imaging system with the 4T MRI system is realized by incorporating a fiber adaptive interface inside the MR magnet. Coregistration is achieved by a special probe design utilizing fiducial markers. A finite element algorithm is used to solve the diffusion equation and an inverse solver based on this forward solver is implemented to calculate the absorption and scattering maps from the acquired data. The MR a priori information is used to guide the optical reconstruction algorithm. Phantom studies show that the absorption coefficient of a 7 mm inclusion in an irregular object located in 64 mm phantom is recovered with 11% error when MR a priori information is used. ENU induced tumor model is used to test the performance of the system in vivo.
Guinea pig maximization test: Podophyllum lignans

The guinea pig maximization test was used to study the sensitizing potential of Podophyllum lignans; 0.5% of each drug in propylene glycol was used for induction and 0.01%, 0.05% 0.1% and 0.5% preparations for topical challenge. The 0.1% and 0.5% preparations caused non‐allergic toxic reactions associated with the cutaneous destructive influence of these drugs; allergic responses did not occur.

Growing Heterotopic Calcification in the Prevertebral Space of a Cervical Spine as a Late Complication of Irradiation: Case Report

Heterotopic calcification following head and neck irradiation has rarely been reported. It usually develops as a late complication of radiotherapy in patients with malignancies, including breast cancer, lymphoma, and genitourinary malignancies. The occurrence of heterotopic calcification in the prevertebral space of the cervical spine has not been described as a late complication of irradiation. Here, we report a case of prevertebral heterotopic calcification in a patient with history of chemotherapy and radiotherapy for tonsil cancer 21 years ago.
Community falls prevention for people who call an emergency ambulance after a fall: randomised controlled trial

Objective To evaluate whether a service to prevent falls in the community would help reduce the rate of falls in older people who call an emergency ambulance when they fall but are not taken to hospital. Design Randomised controlled trial. Setting Community covered by four primary care trusts, England. Participants 204 adults aged more than 60 living at home or in residential care who had fallen and called an emergency ambulance but were not taken to hospital. Interventions Referral to community fall prevention services or standard medical and social care. Main outcome measures The primary outcome was the rate of falls over 12 months, ascertained from monthly diaries. Secondary outcomes were scores on the Barthel index, Nottingham extended activities of daily living scale, and falls efficacy scale at baseline and by postal questionnaire at 12 months. Analysis was by intention to treat. Results 102 people were allocated to each group. 99 (97%) participants in the intervention group received the intervention. Falls diaries were analysed for 88.6 person years in the intervention group and 84.5 person years in the control group. The incidence rates of falls per year were 3.46 in the intervention group and 7.68 in the control group (incidence rate ratio 0.45, 95% confidence interval 0.35 to 0.58, P<0.001). The intervention group achieved higher scores on the Barthel index and Nottingham extended activities of daily living and lower scores on the falls efficacy scale (all P<0.05) at the 12 month follow-up. The number of times an emergency ambulance was called because of a fall was significantly different during follow-up (incidence rate ratio 0.60, 95% confidence interval 0.40 to 0.92, P=0.018). Conclusion A service to prevent falls in the community reduced the fall rate and improved clinical outcome in the high risk group of older people who call an emergency ambulance after a fall but are not taken to hospital.

Disparity measurement using dynamic programming

In this paper, we proposed a method of depth map measurement with dynamic programming which calculates the disparity of binocular stereo camera. We scan the intensity horizontally of the two images captured by the stereo camera and record the cumulative error value of each pixel in the scanline to find the minimum cumulative error to get the optimized path. With the optimized path, we can find the reasonable and dense depth map. Furthermore, in order to reach real-time processing, we proposed a simplifying algorithm to reduce the computational complexity of dynamic programming.
Hemispheric Specialization for Handwriting in Right Handers

Hand preference may be related to either lateralized language, movement representations, or both. Anatomic and behavioral studies have revealed that whereas each hemisphere has motor control of the contralateral distal and proximal limb movements, this same hemisphere's control over the ipsilateral limb is limited to proximal movements. This differential proximal-versus-distal organization may have functional implications such that when right handers write with their left hand they must be use more proximal musculature than when they write with their right hand. If hand preference is related to lateralized movement representations, right handers may also use more proximal than distal movements when drawing with their left than with their right hand. If one uses distal musculature to write or draw, the elbow travels through space less than if one uses proximal musculature. We studied 12 right handers by having them write and draw with their right and left hands and measured the spatial amplitude of their elbow movements. We found that when writing or drawing, right handers moved their left elbow more than their right. These results suggest that it is the lateralized movement representations that may be primarily responsible for writing hand preference.
The Role of PTSD and Length of Shelter Stay in Battered Women's Severity of Reabuse after Leaving Shelter

Intimate partner violence (IPV) is associated with significant morbidity, including high rates of reabuse even after women have taken steps to achieve safety. This study evaluated the roles of posttraumatic stress disorder (PTSD) symptom severity and length of shelter stay in the severity of reabuse in 103 IPV victims over a six-month period after leaving a battered women's shelter. Results suggest that the length of shelter stay is inversely related to reabuse severity after leaving shelter. Additionally, more severe PTSD symptoms on shelter exit were associated with greater reabuse severity after leaving shelter. Furthermore, additional study findings support prior research suggesting that the emotional numbing symptoms of PTSD are a significant risk factor for reabuse among IPV victims after leaving shelter.
ECHO : A reliable distributed cellular core network for public clouds

Economies of scale associated with public cloud platforms offer flexibility and cost-effectiveness, resulting in various services and businesses moving to the cloud. One area with little progress is cellular core networks. A cellular core network manages states of cellular clients; it is essentially a large distributed state machine with very different virtualization challenges compared to typical cloud services. In this paper we present a novel cellular core network architecture, called ECHO1, particularly suited to public cloud deployments, where the availability guarantees might be an order of magnitude worse compared to existing (redundant) hardware platforms. We present the design and implementation of our approach and evaluate its functionality on a public cloud platform.
Expression of vascular endothelial growth factors A and C in human pancreatic cancer.

AIM To study the expression of vascular endothelial growth factor A (VEGF-A) and VEGF-C and to determine whether the presence of VEGF-A and VEGF-C was associated with the clinicopathologic characteristics of pancreatic cancer. METHODS VEGF-A and VEGF-C mRNA transcripts were examined by Northern blot in 6 human pancreatic cancer cell lines and 8 normal pancreatic tissues and 8 pancreatic carcinoma specimens. The expression of VEGF-A and VEGF-C proteins was examined by Western blot in the tested cell lines and by immunohistochemical stain in 50 pancreatic carcinoma samples. RESULTS VEGF-A and VEGF-C mRNA transcripts were present in all the 6 human pancreatic cancer cell lines. Immunoblotting revealed the presence of VEGF-A and VEGF-C proteins in all the cell lines. Northern blot analysis of total RNA revealed 3.0-fold and 3.6-fold increase in VEGF-A and VEGF-C mRNA transcript in the cancer samples, respectively. Immunohistochemical analysis confirmed the expression of VEGF-A and VEGF-C in cancer cells within the tumor mass. Immunohistochemical analysis of 50 pancreatic cancer tissue samples revealed the presence of VEGF-A and VEGF-C immunoreactivity in 50% and 80% of the cancer tissue samples, respectively. The presence of VEGF-A in these cells was associated with larger tumor size and enhanced local spread (c2 = 6.690, P = 0.035<0.05) but was not associated with decreased patient survival. However, the presence of VEGF-C in the cancer cells was associated with increased lymph node metastasis (c2 = 5.710, P = 0.017 < 0.05), but was not associated with decreased patient survival. There was no correlation between the expression of VEGF-A and VEGF-C in the same cancer cells. CONCLUSION VEGF-A and VEGF-C are commonly overexpressed in human pancreatic cancer and may contribute to tumor growth and lymph node metastasis. There is no relationship between the expression of VEGF-A and VEGF-C in pancreatic cancer.
Pharyngeal airway changes in pre-pubertal children with Class II malocclusion after Fränkel-2 treatment.

AIM To evaluate two-dimensional changes in pharyngeal airway dimensions in pre-pubertal children with a Class II malocclusion treated with a Fränkel-2 appliance compared to a matched non-treated control sample. MATERIALS AND METHODS Lateral cephalograms obtained from 28 consecutively treated pre-pubertal children before (T0) and after (T1) a one-year Fränkel-2 treatment were analysed. Fränkel-2 appliance was used for at least 18 hr/day during 12 months. The control group was matched as closely as possible. All the cases presented normal facial growth pattern. Sagittal and vertical cephalometric measurements assessing maxillary and mandibular skeletal positions, as well as sagittal pharyngeal airway dimensions, were calculated. Intraclass correlation coefficient was calculated in order to determine reliability. Differences based on age for all the outcome variables at T0 were compared with an independent t-test. A MANOVA was used thereafter to determine if any factors and their interactions were associated with changes in the outcome variables. Differences between T1 and T0 were evaluated with either a t-student test or a Mann Whitney U test. RESULTS At T0 differences between groups were noted for several variables. These differences were considered during the follow-up statistical analysis. Changes between groups after treatment (T1-T0) were noted for SNB, PNS to Ba, McNamara Low and Middle to S (increase in treatment group), and ANB and AD1 to Ba (decrease in treatment group). CONCLUSIONS Some pharyngeal two-dimensional airway dimensions changed in Class II malocclusion pre-pubertal patients during a one-year treatment with Fränkel-2 appliances.
