Effect of intercell interference on the SNIR of a multihop cellular network

In a multihop cellular network, the physical layer of mobile terminals is modified so that in addition to being able to transmit to base stations, mobile terminals are able to transmit directly to other mobile terminals. This allows mobile terminals to lower their maximum transmission power and use other terminals as repeaters to forward their packets to the base station. Multihop cellular networks may have a higher capacity than traditional cellular networks due to their potential of lower intercell interference. Intercell interference may be lower because the maximum transmission power of terminals is decreased. The effects of intercell interference in a multihop cellular network is investigated in this paper. Previous simulation results of a one-cell system show that the SNIR of a multihop cellular network is slightly lower than that of a traditional cellular network. However, our simulations of a network with many cells show that the overall SNIR of a multihop cellular network is in fact higher than in a traditional cellular network because of lower intercell interference. Previous simulation results of a one-cell system show that the total energy consumption of a multihop cellular network is lower than that of a traditional cellular network. Our simulations of a multihop cellular network show that the savings in energy consumption are even greater when a network with many cells is considered.
The effects of supraphysiologic doses of testosterone on muscle size and strength in normal men.

BACKGROUND
Athletes often take androgenic steroids in an attempt to increase their strength. The efficacy of these substances for this purpose is unsubstantiated, however.


METHODS
We randomly assigned 43 normal men to one of four groups: placebo with no exercise; testosterone with no exercise; placebo plus exercise; and testosterone plus exercise. The men received injections of 600 mg of testosterone enanthate or placebo weekly for 10 weeks. The men in the exercise groups performed standardized weight-lifting exercises three times weekly. Before and after the treatment period, fat-free mass was determined by underwater weighing, muscle size was measured by magnetic resonance imaging, and the strength of the arms and legs was assessed by bench-press and squatting exercises, respectively.


RESULTS
Among the men in the no-exercise groups, those given testosterone had greater increases than those given placebo in muscle size in their arms (mean [+/-SE] change in triceps area, 424 +/- 104 vs. -81 +/- 109 square millimeters; P < 0.05) and legs (change in quadriceps area, 607 +/- 123 vs. -131 +/- 111 square millimeters; P < 0.05) and greater increases in strength in the bench-press (9 +/- 4 vs. -1 +/- 1 kg, P < 0.05) and squatting exercises (16 +/- 4 vs. 3 +/- 1 kg, P < 0.05). The men assigned to testosterone and exercise had greater increases in fat-free mass (6.1 +/- 0.6 kg) and muscle size (triceps area, 501 +/- 104 square millimeters; quadriceps area, 1174 +/- 91 square millimeters) than those assigned to either no-exercise group, and greater increases in muscle strength (bench-press strength, 22 +/- 2 kg; squatting-exercise capacity, 38 +/- 4 kg) than either no-exercise group. Neither mood nor behavior was altered in any group.


CONCLUSIONS
Supraphysiologic doses of testosterone, especially when combined with strength training, increase fat-free mass and muscle size and strength in normal men.
Shared leadership in enterprise resource planning and human resource management system implementation

Human resource management systems (HRMS) integrate human resource processes and an organization's information systems. An HRMS frequently represents one of the modules of an enterprise resource planning system (ERP). ERPs are information systems that manage the business and consist of integrated software applications such customer relations and supply chain management, manufacturing, finance and human resources. ERP implementation projects frequently have high failure rates; although research has investigated a number of factors for success and failure rates, limited attention has been directed toward the implementation teams, and how to make these more effective. In this paper we argue that shared leadership represents an appropriate approach to improving the functioning of ERP implementation teams. Shared leadership represents a form of team leadership where the team members, rather than only a single team leader, engage in leadership behaviors. While shared leadership has received increased research attention during the past decade, it has not been applied to ERP implementation teams and therefore that is the purpose of this article. Toward this end, we describe issues related to ERP and HRMS implementation, teams, and the concept of shared leadership, review theoretical and empirical literature, present an integrative framework, and describe the application of shared leadership to ERP and HRMS implementation.

Novel application of a Wii remote to measure spasticity with the pendulum test: Proof of concept.

BACKGROUND
The pendulum test is a standard clinical test for quantifying the severity of spasticity. In the test, an electrogoniometer is typically used to measure the knee angular motion. The device is costly and difficult to set up such that the pendulum test is normally time consuming.


OBJECTIVE
The goal of this study is to determine whether a Nintendo Wii remote can replace the electrogroniometer for reliable assessment of the angular motion of the knee in the pendulum test.


METHODS
The pendulum test was performed in three control participants and 13 hemiplegic stroke patients using both a Wii remote and an electrogoniometer. The correlation coefficient and the Bland-Altman difference plot were used to compare the results obtained from the two devices. The Wilcoxon signed-rank test was used to compare the difference between hemiplegia-affected and nonaffected sides in the hemiplegic stroke patients.


RESULTS
There was a fair to strong correlation between measurements from the Wii remote and the electrogoniometer (0.513<R(2)<0.800). Small but consistent differences between the Wii remote and electrogoniometer were identified from the Bland-Altman difference plot. Within the hemiplegic stroke patients, both devices successfully distinguished the hemiplegia-affected (spastic) side from the nonaffected (nonspastic) side (both with p<.0001*). In addition, the intraclass correlation coefficient, standard error of measurement, and minimum detectable differences were highly consistent for both devices.


CONCLUSION
Our findings suggest that the Wii remote may serve as a convenient and cost-efficient tool for the assessment of spasticity.
Optimization on TEEN routing protocol in cognitive wireless sensor network

In order to improve the energy efficiency of cognitive wireless sensor network, this paper introduces threshold-sensitive energy efficient sensor network (TEEN) routing protocol into cognitive wireless sensor network. To make routing and spectrum more stable, this paper presents advanced threshold-sensitive energy efficient sensor network (A-TEEN), which is the optimization of TEEN. A-TEEN optimized the cluster head election method compared with TEEN. Simulation result shows that compared with low-energy adaptive clustering hierarchy, TEEN increases the energy efficiency and extends life cycle of cognitive wireless sensor network. A-TEEN improves the energy efficiency and lifetime further operating in the same settings compared with the regular TEEN.

Smart work-assisting gear

This paper describes the use of IoT hardware and protocols to build a smart device which assists factory workers and other employees. This gear is a wearable glove device which can be used in various work spaces where power tools are being constantly used. This proposed system is built around a micro-processor acting as the central server, while many sensors are interfaced with microcontrollers, which act as the link for data transmission and perform various tasks. One of the microcontrollers acts as the master, which controls the other microcontrollers attached to various sensors. The master contains an LCD screen and few buttons, which can control the menu being shown on the screen. This can control the other sensors, and read the data in real time. The gloves contain safety features so that the workers are unable to use any dangerous power tools without wearing proper equipment. The glove will act as a security measure in such a way that each tool will have restricted access, according to the level of expertise of the worker. The glove can also restrict the access to the tools which are being used actively during a particular time-frame. The entire data is actively logged by the central server and various other sensors such as heat sensor, temperature sensor and vibration sensors can be attached and monitored by the master glove. The system also has an extra capability of analyzing tone of the workers so that whenever the user gets hurt and shouts in pain, the analysis function can classify the pain and call for medical help accordingly. A simple sweep based camera module is used alongside the central server to record and live-stream the captured video whenever any power tool is switched On. This system proliferates the value of safety of a worker in a factory floor.

Data utilization for medical decision making at the time of patient admission to ICU.

OBJECTIVES
Information overload in electronic medical records can impede providers' ability to identify important clinical data and may contribute to medical error. An understanding of the information requirements of ICU providers will facilitate the development of information systems that prioritize the presentation of high-value data and reduce information overload. Our objective was to determine the clinical information needs of ICU physicians, compared to the data available within an electronic medical record.


DESIGN
Prospective observational study and retrospective chart review.


SETTING
Three ICUs (surgical, medical, and mixed) at an academic referral center.


SUBJECTS
Newly admitted ICU patients and physicians (residents, fellows, and attending staff).


MEASUREMENTS AND MAIN RESULTS
The clinical information used by physicians during the initial diagnosis and treatment of admitted patients was captured using a questionnaire. Clinical information concepts were ranked according to the frequency of reported use (primary outcome) and were compared to information availability in the electronic medical record (secondary outcome). Nine hundred twenty-five of 1,277 study questionnaires (408 patients) were completed. Fifty-one clinical information concepts were identified as being useful during ICU admission. A median (interquartile range) of 11 concepts (6-16) was used by physicians per patient admission encounter with four used greater than 50% of the time. Over 25% of the clinical data available in the electronic medical record was never used, and only 33% was used greater than 50% of the time by admitting physicians.


CONCLUSIONS
Physicians use a limited number of clinical information concepts at the time of patient admission to the ICU. The electronic medical record contains an abundance of unused data. Better electronic data management strategies are needed, including the priority display of frequently used clinical concepts within the electronic medical record, to improve the efficiency of ICU care.

Renal involvement in Churg-Strauss syndrome.

BACKGROUND
Churg-Strauss syndrome (CSS) is a rare disorder characterized by asthma, eosinophilia, and systemic vasculitis. Renal involvement is not regarded as a prominent feature, and its prevalence and severity vary widely in published reports that usually refer to small series of selected patients.


METHODS
We examined the prevalence, clinicopathologic features, and prognosis of renal disease in 116 patients with CSS.


RESULTS
There were 48 men and 68 women with a mean age of 51.9 years (range, 18 to 86 years). Signs of renal abnormalities were present in 31 patients (26.7%). Rapidly progressive renal insufficiency was documented in 16 patients (13.8%); urinary abnormalities, 14 patients (12.1%); and chronic renal impairment, 1 patient. There were 3 additional cases of obstructive uropathy. Sixteen patients underwent renal biopsy, which showed necrotizing crescentic glomerulonephritis in 11 patients. Other diagnoses were eosinophilic interstitial nephritis, mesangial glomerulonephritis, and focal sclerosis. Antineutrophil cytoplasmic antibody (ANCA) was positive in 21 of 28 patients (75.0%) with nephropathy versus 19 of 74 patients without (25.7%; P < 0.001). In particular, all patients with necrotizing crescentic glomerulonephritis were ANCA positive. After a median follow-up of 4.5 years, 10 patients died (5 patients with nephropathy) and 7 patients developed mild chronic renal insufficiency. Five-year mortality rates were 11.7% (95% confidence interval, 3.9 to 33.3) in patients with nephropathy and 2.7% (95% confidence interval, 0.7 to 10.7) in those without (P = 0.10).


CONCLUSION
Renal abnormalities are present in about one quarter of patients with CSS. The prevailing picture is ANCA-associated necrotizing crescentic glomerulonephritis; however, other forms of nephropathy also may occur. Outcome and long-term follow-up usually are good.

Factor analysis of the WeeFIM in children with spastic cerebral palsy.

PURPOSE
Determining the psychometric properties such as reliability and validity of Functional Independence Measure for Children (WeeFIM) instrument would help health professionals to understand the comprehensive assessment of children with spastic cerebral palsy (CP). The purpose of this study was to investigate the factor structure of the WeeFIM in children with spastic CP.


METHODS
Two hundred seven children (138 boys, 69 girls) with spastic CP were recruited in this cross-sectional study; their mean age (SD) was 9.10 (2.7) years. Data were collected through a questionnaire that included the WeeFIM. Of the 207 children, 57 (27%), 105 (51%), and 45 (22%) were quadriplegic, diplegic, and hemiplegic, respectively. In each of these groups, 49 (24%), 32 (15%), 31 (15%), 19 (9%), and 76 (37%) children were classified as Gross Motor Function Classification System (GMFCS) levels I-V, respectively. The factor structure of the WeeFIM was analyzed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) by using AMOS 20.0. The reliability of WeeFIM was assessed by calculating the internal consistency of Cronbach's α.


RESULTS
The internal consistency of Cronbach's α was 0.98. The 1- and 2-factor models did not demonstrate adequate fit indices according to CFA. However, the 3-factor structure (i.e. self-care, motor, and cognitive factors) was supported by EFA and CFA, which explained 87.12% of the variance. The self-care factor included 6 items (eating, grooming, dressing upper, dressing lower, bathing, and toileting), the motor factor included 7 items (bladder and bowel management, bed/chair/wheelchair, toilet, tub/shower, walk/wheelchair, and stairs), and the cognitive factor included the same 5 items as the original cognitive domain.


CONCLUSION
In children with spastic CP, 3 factors of the WeeFIM were determined by factor analysis. Therefore, self-care, motor, and cognitive domains should be treated as separate scales in children with spastic CP.
Validation of the Spanish versions of the long (26 items) and short (12 items) forms of the Self-Compassion Scale (SCS)

BACKGROUND
Self-compassion is a key psychological construct for assessing clinical outcomes in mindfulness-based interventions. The aim of this study was to validate the Spanish versions of the long (26 item) and short (12 item) forms of the Self-Compassion Scale (SCS).


METHODS
The translated Spanish versions of both subscales were administered to two independent samples: Sample 1 was comprised of university students (n = 268) who were recruited to validate the long form, and Sample 2 was comprised of Aragon Health Service workers (n = 271) who were recruited to validate the short form. In addition to SCS, the Mindful Attention Awareness Scale (MAAS), the State-Trait Anxiety Inventory-Trait (STAI-T), the Beck Depression Inventory (BDI) and the Perceived Stress Questionnaire (PSQ) were administered. Construct validity, internal consistency, test-retest reliability and convergent validity were tested.


RESULTS
The Confirmatory Factor Analysis (CFA) of the long and short forms of the SCS confirmed the original six-factor model in both scales, showing goodness of fit. Cronbach's α for the 26 item SCS was 0.87 (95% CI = 0.85-0.90) and ranged between 0.72 and 0.79 for the 6 subscales. Cronbach's α for the 12-item SCS was 0.85 (95% CI = 0.81-0.88) and ranged between 0.71 and 0.77 for the 6 subscales. The long (26-item) form of the SCS showed a test-retest coefficient of 0.92 (95% CI = 0.89-0.94). The Intraclass Correlation (ICC) for the 6 subscales ranged from 0.84 to 0.93. The short (12-item) form of the SCS showed a test-retest coefficient of 0.89 (95% CI: 0.87-0.93). The ICC for the 6 subscales ranged from 0.79 to 0.91. The long and short forms of the SCS exhibited a significant negative correlation with the BDI, the STAI and the PSQ, and a significant positive correlation with the MAAS. The correlation between the total score of the long and short SCS form was r = 0.92.


CONCLUSION
The Spanish versions of the long (26-item) and short (12-item) forms of the SCS are valid and reliable instruments for the evaluation of self-compassion among the general population. These results substantiate the use of this scale in research and clinical practice.
Ancient Theory about Public Health through Physical Activity against Hyperlipidemia and Ischemic Heart Disease

Myocardial infarction is one of the most important causes for global death (1). Apparently there are very high prevalence cardiovascular disease risk factors such as obesity and dyslipidemia among middle-aged women in Babol, northern Iran. Furthermore there is a relation between physical activity (PA) and dyslipidemia (2). Some studies describe protective effect of physical activity against hyperlipidemia (3) which is a known risk factor for Ischemic Heart Disease (IHD) (4). Cardioprotective effects of PA are now being acknowledged by the medical community (5). In this study we show a simple model for protective effect of PA against hyperlipidemia and then IHD based on teaching of Avicenna. In third book of ''The Canon of Medicine'', Avicenna has told about cardiovascular diseases and some risk factors for them such as excessive exercise. He has explained some protective factors against diseases generally such as PA in book one when he told about hygiene (6). He believed that PA could prevent from "humoral diseases'' and ''dystemperament'' which is followed by them. It means that there are some diseases which are caused by some materials because of changing either their quality or their quantity; so, they can prepare a plotting to produce some new diseases which can change human temperament named as ''dystemperament''. Both of these two conditions can be prevented by PA because it results in provoking innating heat and facilitation of disposing certain accumulated wastes. Since embryo is created, innating heat is produced and is a trigger for any movement and any function in human body; so, all organs need to it to do their functions. Decreasing innating heat over the time, organs' function will be weakened. Everything that could preserve this heat and prevent from its decline could prevent from weakening of organs , function. The only preservation factor is exercise; so, it is the sole factor which can project organs , function in an appropriate level. For example, appropriate digestion of food results in normal humors production. Weakening digestion due to instinctive heat decreasing, results in making abnormal humors. Localized accumulation of abnormal humors in vessels or other spaces may result in obstruction. Generalized accumulation may fill vessels or spaces and constrict them without any obstruction; so, blood and soul cannot receive to tissues. Avicenna says that the worth obstruction is obstruction of vessels specially arteries and in particular, obstruction of arteries of chief organs: heart, brain, and liver. Following reinforcing …
Just in time , total quality management , and supply chain management : understanding their linkages and impact on business performance

In recent years, numerous approaches have been proposed to improve operations performance. Three in particular, just in time, supply chain management, and quality management, have received considerable attention.While the three are sometimes viewed and implemented as if they were independent and distinct, they can also be used as three prongs of an integrated operations strategy. This study empirically examines the extent to which just in time, supply chain management, and quality management are correlated, and how they impact business performance. Results demonstrate that at both strategic and operational levels, linkages exist between how just in time, total quality management, and supply chain management are viewed by organizations as part of their operations strategy. Results also indicate that a commitment to quality and an understanding of supply chain dynamics have the greatest e5ect on performance. ? 2004 Elsevier Ltd. All rights reserved.
