Second-order statistics blind MIMO-FIR channel equalization for antenna array-based wireless communications systems

A theoretic framework on blind MIMO-FlR channel equalization by use of SOS (second-order statistics) is established. First, a sufficient condition is given on the autocorrelations of source signals. Under this condition, it is guaranteed that an MIMO-FIR channel is equalized up to some scalar factors and some delays if, and only if, some SOS of the composite output signals are the same as that of the source signals. Subsequently, the concept of pre-filters are introduced to convert white sources, which do not satisfy this sufficient condition, into color ones that do satisfy it. Based on the sufficient condition and the pre-filters, a set of theorems are developed for blind MIMO-FIR channel equalization, which only use the SOS of the received signals. Finally, a computer simulation is conducted to verify this theory. The theory and methods can be applied to antenna array-based wireless communications systems for high bandwidth efficiency.

In Medical Education of Sriwijaya University, smoking had no significant effect on reducing the levels of SOD.
Treatment Advances in Locally Advanced and Metastatic Non-Small Cell Lung Cancer

textabstractLung cancer is the leading cause of cancer mortality in the United States and Europe. Approximately 85% of the patients with lung cancer have non–small cell lung cancer (NSCLC), which can be classified into squamous, adeno, large cell and not otherwise specified (NOS) histologies. The most common histologies are: adenocarcinoma ( 50%), squamous cell ( 20%), and large cell ( 10%). More than two third of the patients have locally advanced or metastatic disease at the time of diagnosis.
A study of bacterial sepsis and its relation to thrombocytopenia in neonates

Background: In developing countries like India, the culture facilities are non-existent in most of the district hospitals, so the burden of identification of sepsis lies on hematological investigations like platelet count and white blood cells and very few indian studies have been done to show the association . Objectives: 1) To know the incidence of thrombocytopenia in babies with proven bacterial sepsis. 2) To find, if any, species specific differences in severity and incidence of thrombocytopenia. 3) Clinical outcomes in thrombocytopenic and nonthrombocytopenic septic babies. Methods: It is a prospective observational hospital based study. All the neonates admitted to our NICU with probable sepsis were screened for sepsis and neonates with birth weight of 1000 grams and above with blood and/or Cerebrospinal Fluid (CSF) culture positivity for bacterial growth were recruited during the study period from November 2011 to October 2012. A total of 100 neonates with blood and/or CSF culture positivity for bacterial growth were considered convenient for the study. Results: During the present study period of 1 year we had a total of 960 Neonates admitted to our NICU. 475 neonates were screened for sepsis. A total of 100 neonates with blood and/or CSF culture positivity for bacterial growth were considered for the study. Klebsiella pneumoniae sepsis was the highest contributor to the severe thrombocytopenia category (15 out of 29cases). Out of the 100 cases, 41 had normal platelet count and 59 had thrombocytopenia. Klebsiella positivity was more significantly associated with severe thrombocytopenia than MRCONS positivity or rest of the cultures combined together (p value <0.01). Although there was no significant association between thrombocytopenia and mortality (p=0.176), the proportion of children with severe thrombocytopenia was significantly higher in babies who expired (25% vs 9%) when compared to babies who survived . Conclusions: Our study shows that in our setting bacterial sepsis is significantly complicated by thrombocytopenia. Severe thrombocytopenia in a suspected case of bacterial sepsis might predict Klebsiella species sepsis and hence it may be prudent to start empirical antibiotics covering the Klebsiella species.
Recognizing and reporting domestic violence: A survey of dental practitioners

A survey was sent to 1,000 Colorado dentists to evaluate their recognition and reporting of child, elder, and spouse abuse. Approximately 40% of the dentists returned the survey. In answering questions about suspected and reported cases of child abuse, 29% of the respondents indicated that they had suspected at least one of their patients to be a victim of child abuse, while 14% of the respondents had actually reported at least one case. Only 7% of the responding dentists had ever suspected a case of elder abuse, while just over 1% indicated that they had reported at least one suspected elder abuse case to authorities. When asked about their recognition and reporting of spouse abuse, 30% of the responding practitioners had suspected at least one case, while only 3% had ever actually reported a case to authorities. The overwhelming majority of responding dentists indicated that they needed to know more about child, elder, and spouse abuse.
Interventions to prevent non-critical care hospital acquired pneumonia - a systematic review

Background: Hospital-acquired pneumonia is a significant burden to healthcare systems around the world. Although there is a considerable body of evidence on prevention of ventilator associated pneumonia, less is known about strategies to prevent hospital-acquired pneumonia in non-critical care settings. Objective: To systematically review the randomised controlled trial evidence for prevention of hospitalacquired pneumonia in non-critical care settings. Methods: We searched EMBASE, CINAHL+, MEDLINE and the Cochrane Library. Seventeen different searches were conducted in parallel through each database. Studies were included if they were randomised controlled trials reporting hospital-acquired pneumonia as an endpoint. Studies were excluded if they were performed in critical care or community settings. All studies published up to the end of December 2014 were considered, with no language restrictions. Data were independently extracted by two authors and the Delphi risk of bias tool was applied to assess trial quality. Results: Five thousand one hundred and one titles were identified across 17 searches. Only two studies were eligible for inclusion in the final review, one from a search of physical therapy interventions and one from a search of enteral feeding. The heterogeneity of the interventions did not permit metaanalysis. One trial suggested possible benefits to early mobilisation; the other trial suggested no benefit or harm from early enteral feeding via nasogastric tube. Both trials enrolled patients with acute stroke. No trials in non-stroke, non-critical care populations were eligible for inclusion in the review. Conclusions: There is currently insufficient trial evidence on preventing non-critical care hospitalacquired pneumonia to make recommendations on practice. 2015 Elsevier Masson SAS and European Union Geriatric Medicine Society.

Lipid Profiles with Increase Blood Lead Level: Risk of Cardiovascular Disease in Battery Workers of Lucknow City

In order to investigate the effects of lead exposure on risk of cardiovascular disease during Occupational battery workers i.e. lead exposure, plasma cholesterol and its fractions as high-density lipoprotein (HDL), low-density lipoprotein (LDL) and triglyceride (T.G.) were determined in various battery workers in Lucknow city U.P., India. Increased risk of cardiovascular disease was observed in the various battery workers. Total cholesterol in the battery workers and control group was 142.14±31.92 (mg/dl) and 95.72±11.57 (mg/dl) respectively, which is higher in the battery workers than that of present in control group, While LDL cholesterol in the battery workers and control group was 158.30±22.70 (mg/dl) and 103.77± 4.62 (mg/dl) respectively. HDL cholesterol in the battery workers and control group was 38.80±10.13 (mg/dl) and 65.53±6.52 (mg/dl) respectively.
Characterization of hydrocyclone-separated eucalypt fibre fractions

Lors du fractionnement d'une pâte chimique de feuillus, la caracterisation des fractions de fibres separees a represente un obstacle majeur a la comprehension du processus de fractionnement. Dans la presente etude, l'analyse d'images et la microscopie confocale sont utilisees pour determiner les dimensions transversales des fibres. Ces donnees sont a leur tour utilisees pour calculer la masse volumique apparente des fibres. Les mesures des fractions de refus de classage et d'acceptes indiquent clairement que cette masse volumique apparente est l'un des principaux facteurs controlant le classage par epurateur tourbillonnaire. Les mesures des fibres obtenues concordent avec et aident a expliquer les differences de proprietes physiques des feuilles d'essai fabriquees a partir des fractions de refus et d'acceptes.
Transatrial Approach to Total Correction of Tetralogy of Fallot

A transatrial approach to total correction of the tetralogy of Fallot is presented which utilizes: (1) anteroposterior incision of the right atrium near the right atrioventricular groove; (2) circumferential detachment of the septal leaflet of the tricuspid valve near the annulus; (3) pulmonary arteriotomy with valvuloplasty, if necessary; (4) retrograde displacement and resection of the stenosed infundibulum through the right atrium; (5) closure of the ventricular septal defect; (6) closure of the incision in the tricuspid valve; and (7) closure of the atriotomy.Clinical application to 10 consecutive patients, varying from acyanotia to severely cyanotic, has confirmed the advantages and simplicity of this method. Coronary arterial division, ventriculotomy, and external enlargement of the pulmonary outflow tract have been unnecessary. Relief of pulmonary stenosis has been adequate in each instance. The ventricular septal defect has been well exposed in each patient, and its closure has presented no special problem.There have been no complications associated with the method, and postoperative cardiac function has been good. Operative as well as clinical features of the method are still under investigation; however, experience thus far has led to its establishment as a routine for total correction of the tetralogy of Fallot in this clinic.
Preparing language teachers for blended teaching of summary writing

Research on preparing language teachers for blended teaching of summary writing, a mix of on-site and online instruction for college students to grasp the gist of the texts, is scarce in higher education. This study examined the problems encountered and solutions proposed by six language teachers, who altogether instructed 214 college students on summary writing. The findings of this study are based on content analyses of the teachers’ interview transcripts, the teachers’ observation of college students’ progress in on-site and online instruction, and the interactions among the students recorded in the log files of the online system. The results show that the language teachers’ problems in blended teaching of summary writing fell into three categories: instructional processes, community concerns, and technical issues. The four main themes that emerged from the three categories include the following: (1) the changing roles of the teachers and students, (2) little sense of community building, (3) lack of training in blended teaching of summary writing, and (4) an unfamiliarity with the new systems or technologies. The language teachers’ perspectives on solving these problems were to (1) distinguish the significant differences between on-site and online language teaching contexts, (2) identify strategies and techniques to facilitate students’ blended learning in summary writing, and (3) develop community building skills to encourage teachers and students to actively participate in collaborative learning. These solutions shed light on the preparation of language teachers in blended teaching of summary writing.

An examination of the reliability and validity of the Aiken and Hage scales of centralization, formalization, and task routineness

March 1980, volume 25 This article examines the reliability and validity of six scales developed by Aiken, Hage, and Hall to operationalize technology, centralization, and formalization. The discussion of the definitions of these constructs suggests a need for revision in the content of the indices of job codification and job specificity. Furthermore, these two indices, designed to operationalize formalization, have serious problems of convergent and discriminant validity while the index of task routineness operationalizes a more limited part of the technology construct than originally proposed by Perrow. The indicators of centralization are found to be both reliable and valid.
Planning, Execution, and Assessment of Effects-Based Operations (EBO)

Abstract : This is the final technical report of the contract entitled "Planning, Execution, and Assessment of Effects Based Operations" that was conducted by George Mason University between 1 May 2001 and 30 September 2005. The overall objective of the effort was to enhance and use a suite of modeling and simulation tools called Computer Aided Evaluation of System Architectures (CAESAR II/EB) to support the warfighter when planning, executing, and assessing Effects-Based Operations (EBO). At the completion of the effort, an integrated EBO tool suite called Pythia had been developed and tested. The tool operates in a single Windows-based environment. It allows analysts to develop and analyze EBO courses of action by creating Timed Influenced Nets that relate potential actions of an overall course of action (COA) to desired and undesired effects. This report documents the EBO concept that was used to develop Pythia, describes the tools, technologies and techniques that support that concept, and documents the key technical feature of Pythia.
Role of Rab7 in the pathogenesis of Charcot-Marie-Tooth Type2B (CMT2B) Disease

Charcot-Marie-Tooth (CMT) Disease is a group of peripheral neuropathies affecting 1 in 2500 individuals. It is characterized by progressive sensory loss and distal muscle weakness affecting mostly the lower extremities that lead to foot deformities. More than thirty genetic loci are affected in this disease, products of which are involved in axonal trafficking. Rab7 is one such gene that gets mutated in CMT Type2B disease. To date four missense mutants of Rab7 have been identified. L129F, K157N, N161T and V162M amino acid substitutions of Rab7 occur in highly conserved regions. Rab7 is a ubiquitous protein but only the peripheral nerves get affected in this disease. This calls for an urgent need to study the pathogenesis of CMT2B disease, the awry molecular mechanisms of
Statin-associated necrotizing autoimmune myopathy

Necrotizing autoimmune myopathy (NAM) is a severe adverse effect of statins. We report a 66-year-old Caucasian female who had progressive proximal muscle weakness after treatment with statins. Results of a muscle biopsy showed necrotizing myopathy with minimal inflammatory cell infiltrate and increased major histocompatibility class I antigen expression in muscle fibers. The clinical and laboratory parameters improved significantly with immunosuppressive treatment. Although it is a rare event, statin-induced NAM should be included as a differential diagnosis of myopathies.
Optimized behavior in a robot model of sequential action

People learn and use complex sequential actions on a daily basis, despite living in a high-dimensional environment and body. Sequential action learning is sometimes studied in cognitive psychology using button-pressing tasks such as Nissen and Bullemer's (1987) serial respone time (SRT) task. However, the SRT task only measures the speed of button presses, neglecting the rich - and difficult to control - trajectory of the arm, which can show predictive movements and other contextual effects. In this study, we evolve neural networks to carry out a mouse-based SRT task under conditions of differing prediction uncertainty. We replicate behaviors found in a recent human experiment, and explore ramifications for human sequence learning.
Power converter for dual-power photovoltaic-grid energy system / Intan Rahayu Ibrahim

High frequency switching activities of power electronic devices in the power converter produce switching losses, harmonic distortions and raise high voltage and magnetic stresses in the power converter circuit, consequently affecting the efficiency and quality of output of the converter. In this research study, a new power converter utilizing low fundamental frequency switching technique is being proposed to resolve harmonics distortion issues. This research aims to develop switching and control technique for power converter in dualpower photovoltaic-grid energy system. 21-level cascaded H-bridge multilevel inverter is developed by cascading five of 5-level H-bridges with five separate PV sources. 5-level H-bridge produces high level of output “stepped” voltage with reduced number of power switches. The optimized switching strategy of proposed MhyPSO technique successfully reduced the THD level to 3.94% in the simulation circuit and 6.7% in the hardware circuit. Each of 5-level H-bridges is equipped with the individual boost regulator embedded with MPPT and battery management system.
