Radio Interferometric Object Tracking

Abstract This paper proposes a novel object tracking method using radio interferometry. The proposed low cost solution is able to track objects, equipped with a radio receiver, in real time, using only simple infrastructure nodes with radio transceivers at fixed and known locations. The localization method has low computational requirements and does not require any preliminary knowledge of, or measurements in the space where tracking is performed. The paper introduces the novel method and preliminary test results are also presented.
Generating and evaluating regrasp operations

Regrasping must be performed whenever a robot's grasp of an object is not compatible with the pick-and-place operation the robot must perform. This paper presents a new approach to the problem of regrasping for a robot arm equipped with a parallel-jaw end-effector. The method employs an evaluated breadth-first search in the space of compatible regrasp operations taking into account several criteria rating about the grasp and placement quality. We pay particular attention to online computational efficiency. The presented system is the first planning system performing as much of offline computation as possible for solving the regrasp problem efficiently online.
Arabic Text Classification Using N-Gram Frequency Statistics A Comparative Study

This paper presents the results of classifying Arabic text documents using the N-gram frequency statistics technique employing a dissimilarity measure called the “Manhattan distance”, and Dice’s measure of similarity. The Dice measure was used for comparison purposes. Results show that N-gram text classification using the Dice measure outperforms classification using the Manhattan measure.
A Hybrid Query Disambiguation Adaptive Approach for Web Information Retrieval

In web searching, trustable and precise results are greatly affected by the inherent uncertainty in the input queries. Queries submitted to search engines are by nature ambiguous and constitute a significant proportion of the instances given to web search engines. Ambiguous queries pose real challenges for the web search engines due to versatility of information. Temporal based approaches whereas somehow reduce the uncertainty in queries but still lack to provide results according to users aspirations. Web search science has created an interest for the researchers to incorporate contextual information for resolving the uncertainty in search results. In this paper, we propose an Adaptive Disambiguation Approach (ADA) of hybrid nature that makes use of both the temporal and contextual information to improve user experience. The proposed hybrid approach presents the search results to the users based on their location and temporal information. A Java based prototype of the systems is developed and evaluated using standard dataset to determine its efficacy in terms of precision, accuracy, recall, and F1-measure. Supported by experimental results, ADA demonstrates better results along all the axes as compared to temporal based approaches.
Experimental characterization of MIMO-UWB multipath underground mine radio channels

This paper reports on experimental results and its interpretations for MIMO-UWB multipath channel. It is intended to help in establishing design guidelines for underground mine wireless communications systems using MIMO-UWB technology. It deals with measurements obtained using two different antenna configurations under line-of-sight (LOS) conditions. Furthermore, the MIMO channel is characterized in terms of channel correlation and capacity. It was shown that a special arrangement of antennas in a MIMO system may reduce channel correlation and improve capacity.
Myosin catalytic domain flexibility in MgADP.

Conventional EPR studies of muscle fibers labeled with a novel alpha-iodoketo spin label at Cys-707 of the myosin head revealed substantial internal domain reorganization on the addition of ADP to rigor fibers. The spin probes that are well-ordered in the rigor state become disordered and form two distinct populations. These orientational changes do not correspond to rotation of the myosin catalytic domain as a whole because other probes (maleimide and iodoacetamide nitroxides attached to the same Cys-707 of myosin head) report only a small (5-10 degrees) torsional rotation and little or no change in the tilt angle [Ajtai et al. (1992) Biochemistry 31, 207-17; Fajer (1994) Biophys. J. 66, 2039-50]. In the presence of ADP, the labeled domain becomes more flexible and executes large-amplitude microsecond motions, as measured by saturation-transfer EPR with rates (tau r = 150 microseconds) intermediate between the rotations of detached (tau r = 7 microseconds) and rigor heads (tau r = 2500 microseconds). This finding contrasts with an absence of global motion of the myosin head in ADP (tau r = 2200 microseconds) as reported by the maleimide spin label. Our results imply that the myosin head in a single chemical state (AM.ADP) is capable of attaining many internal configurations, some of which are dynamic. The presence of these slow structural fluctuations might be related to the slow release of the hydrolysis products of actomyosin ATPase.
PAPR reduced OFDM visible light communication using exponential nonlinear companding

In visible light communication (VLC), LEDs are used to transmit data using intensity modulation. LEDs have a limited operating voltage range and the voltage-current characteristic shows a nonlinear behavior. When an orthogonal frequency division multiplexing (OFDM) signal is used to drive these transmitter LEDs (VLC-OFDM), LED chip overheating and nonlinear distortions occur, due to high peak-to-average power ratio (PAPR) of the OFDM signal. Unlike radio frequency baseband communication systems, the VLC-OFDM signal is a real-valued signal. This would lend itself to the PAPR reduction in VLC-OFDM. In this paper, we propose to use exponential nonlinear companding transformation techniques in VLC-OFDM to reduce the PAPR. Simulation results demonstrate that with the exponential companding function employed in VLC-OFDM, the PAPR of the VLC-OFDM is significantly reduced, compared with previously considered methods.
Risk Factors for a First‐Incident Radiographic Vertebral Fracture in Women ≥65 Years of Age: The Study of Osteoporotic Fractures

Vertebral fractures in older women signal an increased risk of additional osteoporotic fractures. To identify risk factors for first vertebral fractures, we studied 5822 women ≥65 years of age who had no fracture on baseline radiographs of the spine. Several modifiable risk factors increased an older woman's risk of developing a first vertebral fracture, and women with multiple risk factors and low BMD had the highest risk. Risk factors and low BMD should be useful to help focus efforts to prevent these fractures.

Net citation balances: A measure of influence between scientific journals

A probablistic model is applfed to a contingency table with cross-citation frequency counts between scientific journals. The parameters of the applied quasi-symmetry model are considered to reflect size, visibility, centrality, and content-similarity of journals. The net citation balances, i.e., the differences between model-based expected citation frequencies and observed citation frequencies, are used to derive an interjournal “influence” score. The summed scores yield a measure of the overall influence which is compared with two other citation-based disciplinary-oriented methods for ranking journals in an application to a number of core journals in astronomy and astrophysics.
Investigation of Central Pain Processing in Postoperative Shoulder Pain and Disability

Background:Measures of central pain processing like conditioned pain modulation and suprathreshold heat pain response (SHPR) have been described to assess different components of central pain modulatory mechanisms. Central pain processing potentially plays a role in the development of postsurgical pain, however, the role of conditioned pain modulation and SHPR in explaining postoperative clinical pain and disability is still unclear. Methods:Seventy-eight patients with clinical shoulder pain were included in this study. Patients were examined before shoulder surgery, at 3 months, and 6 months after surgery. The primary outcome measures were pain intensity and upper extremity disability. Results:Analyses revealed that the change score (baseline- 3 mo) of fifth pain rating of SHPR accounted for a significant amount of variance in 6-month postsurgical clinical pain intensity and disability after age, sex, preoperative pain intensity, and relevant psychological factors were considered. Conclusions:The present study suggests that baseline measures of central pain processing were not predictive of 6-month postoperative pain outcome. Instead, the 3-month change in SHPR might be a relevant factor in the transition to an elevated 6-month postoperative pain and disability outcomes. In patients with shoulder pain, the 3-month change in a measure of central pain processing might be a relevant factor in the transition to elevated 6-month postoperative pain and disability scores.
The quick and the dead: when reaction beats intention

Everyday behaviour involves a trade-off between planned actions and reaction to environmental events. Evidence from neurophysiology, neurology and functional brain imaging suggests different neural bases for the control of different movement types. Here we develop a behavioural paradigm to test movement dynamics for intentional versus reaction movements and provide evidence for a ‘reactive advantage’ in movement execution, whereby the same action is executed faster in reaction to an opponent. We placed pairs of participants in competition with each other to make a series of button presses. Within-subject analysis of movement times revealed a 10 per cent benefit for reactive actions. This was maintained when opponents performed dissimilar actions, and when participants competed against a computer, suggesting that the effect is not related to facilitation produced by action observation. Rather, faster ballistic movements may be a general property of reactive motor control, potentially providing a useful means of promoting survival.
Generalized communities in networks

A substantial volume of research is devoted to studies of community structure in networks, but communities are not the only possible form of large-scale network structure. Here, we describe a broad extension of community structure that encompasses traditional communities but includes a wide range of generalized structural patterns as well. We describe a principled method for detecting this generalized structure in empirical network data and demonstrate with real-world examples how it can be used to learn new things about the shape and meaning of networks.
Hidden in History: Female Homoeroticism and Women of a "Third Nature" in the South Asian Past

To explore this female third-gender role I shall first consider some of the current theories about alternative genders in traditional societies and then examine the remnants of such genders as still exist in remote regions of India. I shall then survey ancient Sanskrit and later historical documentation of women whose occupations cross-dressing and masculine behavior match what we might expect a third gender to entail. Finally I will discuss the demise of third-gender roles for women in the subcontinent and suggest how further analysis of female gender-variant roles might advance the historiography of gender and sexuality.

Improved Mean Shift Tracking Algorithm by Multi Scale Motion Information

Tracking object algorithms in moving platform environment are a challenging mission because they treat variety of speeds for moving object problems. Common method is Mean Shift Algorithm (MSA) due to its simple and efficient procedure. However, the lack of dynamic window size scale in its target model makes it unsuitable for tracking objects in real applications system. Dual static cameras placed in front and rear moving platform gathered information surrounding moving platform. Since the scale of the targets diverse irregularly there are needs to adjusted bandwidth scale when the appearances of tracking object changes. In this paper an automatic window-size updating method based mean shift with motion information obtained from Optical Flow (OF). Objects move with variety of speeds and directions surrounding moving platform . The proposed module speed and direction of moving object join together as factor updating scale according to how much moving object near or far from camera. Proposed framework initialized by MSA followed by Multi Scale Motion Measurement (MSMM). Experimental results show that scale update could select the proper window size of tracking region depending on speed of moving object. Evaluate performance of MSMM compare with traditional MSA by mismatch ratio and time complexity.
Aortic Intima-Media Thickness, Serum IGF-I, IGFBP-3, and Leptin Levels in Intrauterine Growth-Restricted Newborns of Healthy Mothers

Neonates with intrauterine growth restriction (IUGR) are associated with reduced concentrations of IGF-I that might contribute to arterial wall thickening. Direct atherogenic effects of leptin have been described. We aimed to investigate the relationship among abdominal aortic intima-media thickness (aIMT), serum IGF-I, IGF binding protein-3, and leptin levels in neonates with IUGR. Abdominal aIMT was measured in 40 term neonates with IUGR and in 40 controls. Mean aIMT was significantly greater in neonates with IUGR (0.45 ± 0.03 mm) than in controls (0.39 ± 0.04 mm, p < 0.0001). Serum IGF-I and leptin levels were lower in neonates with IUGR than in controls. There was a significant positive correlation between aIMT and gestational age, whereas a significant negative correlation was determined between aIMT and IGF-I in the IUGR neonates. For aIMT, significant associations included serum IGF-I level (β = –0.406, p = 0.006) and gestational age (β = 0.331, p = 0.022) in a multiple stepwise linear regression analysis. In control neonates, serum IGF-I levels were negatively related to aIMT (β = –0.750, p < 0.001). Neonates with IUGR have significant aIMT with decreased IGF-I. IGF-I levels determine aIMT not only in neonates with IUGR but also in healthy controls.
When Basic Skills and Information Processing Just Aren't Enough: Rethinking Reading in New Times

Is reading simply a matter of neutral information processing or functional skills? This article draws on historical and contemporary perspectives to make the case that reading is a malleable social practice with identifiable moral and ideological consequences. It builds a four-tiered model that defines reading in contemporary social life in terms of four interconnected roles: coding, semantic, pragmatic, and critical. Critical reading—an awareness of and facility with the techniques by which texts and discourses construct and position human subjects and social reality—is an essential component of everyday life in social institutions. This is illustrated through text analyses of three “functional” texts: a textbook passage, a tenancy agreement, and a job application.
Myosin VIIA, Important for Human Auditory Function, Is Necessary for Drosophila Auditory Organ Development

Background Myosin VIIA (MyoVIIA) is an unconventional myosin necessary for vertebrate audition [1]–[5]. Human auditory transduction occurs in sensory hair cells with a staircase-like arrangement of apical protrusions called stereocilia. In these hair cells, MyoVIIA maintains stereocilia organization [6]. Severe mutations in the Drosophila MyoVIIA orthologue, crinkled (ck), are semi-lethal [7] and lead to deafness by disrupting antennal auditory organ (Johnston's Organ, JO) organization [8]. ck/MyoVIIA mutations result in apical detachment of auditory transduction units (scolopidia) from the cuticle that transmits antennal vibrations as mechanical stimuli to JO. Principal Findings Using flies expressing GFP-tagged NompA, a protein required for auditory organ organization in Drosophila, we examined the role of ck/MyoVIIA in JO development and maintenance through confocal microscopy and extracellular electrophysiology. Here we show that ck/MyoVIIA is necessary early in the developing antenna for initial apical attachment of the scolopidia to the articulating joint. ck/MyoVIIA is also necessary to maintain scolopidial attachment throughout adulthood. Moreover, in the adult JO, ck/MyoVIIA genetically interacts with the non-muscle myosin II (through its regulatory light chain protein and the myosin binding subunit of myosin II phosphatase). Such genetic interactions have not previously been observed in scolopidia. These factors are therefore candidates for modulating MyoVIIA activity in vertebrates. Conclusions Our findings indicate that MyoVIIA plays evolutionarily conserved roles in auditory organ development and maintenance in invertebrates and vertebrates, enhancing our understanding of auditory organ development and function, as well as providing significant clues for future research.
Imitation with ALICE: learning to imitate corresponding actions across dissimilar embodiments

Imitation is a powerful mechanism whereby knowledge may be transferred between agents (both biological and artificial). Key problems on the topic of imitation have emerged in various areas close to artificial intelligence, including the cognitive and social sciences, animal behavior, robotics, human-computer interaction, embodied intelligence, software engineering, programming by example and machine learning. Artificial systems used to study imitation can both test models of imitation derived from observational or neurobiological data on imitation in animals and then apply them to different kinds of nonbiological systems ranging from robots to software agents. A crucial problem in imitation is the correspondence problem, mapping action sequences of the demonstrator and the imitator agent. This problem becomes particularly obvious when the two agents do not share the same embodiment and affordances. This paper describes a new general imitation mechanism called ALICE (action learning for imitation via correspondence between embodiments) that specifically addresses the correspondence problem. The mechanism is implemented and its efficacy illustrated on the "chessworld" testbed that was created to study imitation from an agent-based perspective, i.e., by a particular agent in a particular environment.
Cost-effectiveness of quality improvement programs for patients with subthreshold depression or depressive disorder.

OBJECTIVE This study explored the cost-effectiveness of quality-improvement interventions for depression in primary care, relative to usual care, among patients with subthreshold depression or depressive disorder. METHODS A total of 746 primary care patients in managed care organizations with 12-month depressive disorder and 502 with current depressive symptoms but no disorder (subthreshold depression) participated in a group-level randomized controlled trial initiated between June 1996 and March 1997. Matched clinics were randomly assigned to enhanced usual care or one of two quality improvement interventions that provided education to manage depression over time and resources to facilitate access to medication management or psychotherapy for six to 12 months. RESULTS The cost-effectiveness ratio for the pooled intervention groups versus usual care was $2,028 for patients with subthreshold depression (95% confidence interval [CI]=-$17,225 to $21,282) and $53,716 for those with depressive disorder (CI=$14,194 to $93,238), by using a measure of quality-adjusted life years (QALY) based on the 12-Item Short Form Health Survey. Similar results were obtained when alternative QALY measures were used. CONCLUSIONS Although precision was limited, even the upper limit of the 95% CIs suggests that such interventions are as cost-effective for patients with subthreshold depression as are many widely used medical therapies. Despite lack of evidence for efficacy of treatments for subthreshold depression, disease management programs that support clinical care decisions over time for patients with subthreshold depression or depressive disorder can yield cost-effectiveness ratios comparable to those of widely adopted medical therapies. Achieving greater certainty about average cost-effectiveness would require a much larger study.
Dose-ranging study of the performance of the natural oxygen transporter HEMO2 Life in organ preservation.

The intensity of ischemia-reperfusion injury of the donor organ during the preservation phase and after anastomosis is acknowledged as being a key factor for long-term graft outcome. We previously showed that the addition of 5 g/L of the natural oxygen carrier HEMO2 Life was beneficial for the cold static preservation of kidney grafts in both University of Wisconsin (UW) and histidine-tryptophan-ketoglutarate solutions. Herein, we refined these findings by evaluating HEMO2 Life at various dose levels in UW, both in vitro with endothelial cells and in vivo in a pig kidney autotransplantation preclinical model. We showed in vitro that cells were significantly better preserved with HEMO2 Life in a dose-dependent manner, with benefits in terms of survival, metabolic activity, and cellular integrity. In vivo, serum creatinine measurements at reperfusion confirmed the important benefits of HEMO2 Life treatment on function recovery at the dose levels of 1, 2, and 5 g/L. Likewise, histological analysis of kidney parenchyma biopsies from day 7 confirmed the superiority of HEMO2 Life-supplemented UW over UW alone, and there was no difference between the doses. Three months' follow-up confirmed the trend of the first 2 weeks, with creatinine and fibrosis levels similar to those in pretransplant kidneys.
Initialization Errors in Quantum Data Base Recall

This paper analyzes the relationship between initialization error and recall of a specific memory in the Grover algorithm for quantum database search. It is shown that the correct memory is obtained with high probability even when the initial state is far removed from the correct one. The analysis is done by relating the variance of error in the initial state to the recovery of the correct memory and the surprising result is obtained that the relationship between the two is essentially linear.
