Recent literature advances Wi-Fi signals to “see” people’s motions and locations. This paper asks the following question: Can Wi-Fi “hear” our talks? We present WiHear, which enables Wi-Fi signals to “hear” our talks without deploying any devices. To achieve this, WiHear needs to detect and analyze fine-grained radio reflections from mouth movements. WiHear solves this micro-movement detection problem by introducing Mouth Motion Profile that leverages partial multipath effects and wavelet packet transformation. Since Wi-Fi signals do not require line-of-sight, WiHear can “hear” people talks within the radio range. Further, WiHear can simultaneously “hear” multiple people’s talks leveraging MIMO technology. We implement WiHear on both USRP N210 platform and commercial Wi-Fi infrastructure. Results show that within our pre-defined vocabulary, WiHear can achieve detection accuracy of 91% on average for single individual speaking no more than 6 words and up to 74% for no more than 3 people talking simultaneously. Moreover, the detection accuracy can be further improved by deploying multiple receivers from different angles.
Are family-centred principles, functional goal setting and transition planning evident in therapy services for children with cerebral palsy?

BACKGROUND Family-centred service, functional goal setting and co-ordination of a child's move between programmes are important concepts of rehabilitation services for children with cerebral palsy identified in the literature. We examined whether these three concepts could be objectively identified in programmes providing services to children with cerebral palsy in Alberta, Canada. METHODS Programme managers (n= 37) and occupational and physical therapists (n= 54) representing 59 programmes participated in individual 1-h semi-structured interviews. Thirty-nine parents participated in eleven focus groups or two individual interviews. Evidence of family-centred values in mission statements and advisory boards was evaluated. Therapists were asked to identify three concepts of family-centred service and to complete the Measures of Process of Care for Service Providers. Therapists also identified therapy goals for children based on clinical case scenarios. The goals were coded using the components of the International Classification of Functioning Disability and Health. Programme managers and therapists discussed the processes in their programmes for goal setting and for preparing children and their families for their transition to other programmes. Parents reflected on their experiences with their child's rehabilitation related to family-centredness, goal setting and co-ordination between programmes. RESULTS All respondents expressed commitment to the three concepts, but objective indicators of family-centred processes were lacking in many programmes. In most programmes, the processes to implement the three concepts were informal rather than standardized. Both families and therapists reported limited access to general information regarding community supports. CONCLUSION Lack of formal processes for delivery of family-centred service, goal-setting and co-ordination between children's programmes may result in inequitable opportunities for families to participate in their children's rehabilitation despite attending the same programme. Standardized programme processes and policies may provide a starting point to ensure that all families have equitable opportunities to participate in their child's rehabilitation programme.

Field,. laboratory, and.modeling studies of faulted rock yield insight 1Oto the hydraulic character of thrust faults . Late-stage faults comprise foliated and su? par~lel faults, ~ith clay-rich gouge and fracture zones, that YIeld mterpenetratmg layers of low-permeability gou~e and higher-permeab~l~ty damage zones. Laboratory testmg suggests a permeabIlity contrast of two orders of magnitude between gouge and damage zones. Layers of differing permeability lead to overall permeability anisotropy with maximum permeability within the plane of the fault and minimum permeability perpendicular to the fault plane. Numerical modeling of regional-scale fluid flow and heat transport illustrates the impact of fault zone hydrogeology on fl uid flux, fluid pore pressure, and temperature in the vicinity of a crystalline thrust sheet.

During the past decades, high-fidelity realistic simulations of various flying insects exhibiting collective behavior have been broadly used in entertainment industries and virtual reality applications. However, due to the intrinsic complexity and high computational cost, shape constrained simulation of collective behaviors remains a challenging topic. In this paper, we present a robust multi-agent model for largescale controllable shape constrained simulation of flying insects. Specifically, we devise an internal force model to biologically mimic an individual insect. We also propose an external force model based on a trade-off mechanic to guide the insects smoothly deforming into a target shape. Our experimental results and comparative studies show our method is able to simulate realistic and dynamic flying insects with various user-specified shape constraints.
The talk given in RAQIS03 conference, Aneccy, 25-28/03/03

We show the connection between the extended center of the quantum group in roots of unity and the restriction of the XXZ model. We also give explicit expressions for operators that respect the restriction and act on the state space of the restricted models. The formulas for these operators are verified by explicit calculation for third-degree roots; they are conjectured to hold in the general case.
USE OF INERTIAL PROPERTIES TO ORIENT

Recent theoretical and experimental results have demonstrated that it is possible to orient quasi‐spherical objects such as apples by taking advantage of inertial effects during rotation. In practice, an apple rolled down a track consisting of two parallel rails tends to move to an orientation in which the stem/calyx axis is parallel to the plane of the track and perpendicular to the direction of travel as angular velocity increases. In this study, orientation tests were conducted using hothouse, globe, and plum tomatoes to demonstrate that quasi‐spherical produce other than apples could be oriented using inertial effects. In addition, to allow testing of theoretical predictions regarding effects of shape on the orientation process, the three tomato cultivars were selected to correspond to the three shape classes used to for theoretical analyses: elongated, spherical, and squat. Single‐pass and three‐pass orientation rates for hothouse and plum tomatoes were about 90% and 100%, respectively. For the globe tomatoes, which tended to be “perfectly” spherical and which had uniform internal density distributions, three‐pass orientation rates approached 90%. These results support the theoretical finding that it would be relatively easy to orient elongated and squat objects, and more difficult to orient spherical objects. In conclusion, rolling quasi‐spherical produce down tracks consisting of two parallel rails is a commercially viable method for orienting such produce for imaging.
Implementation of Greedy Sequential Unique Path File Carving Algorithm for Fragmented Bitmap Image Files

Forensic Analyst encounters a mixed file fragments in the absence of File Table information i.e., files" metadata. File Carving is a process of reconstructing files from mixed file fragments without using files" metadata. File Carving is an interesting and challenging problem in digital forensics and Data Recovery. Recently there have been number of research papers in the area of File Carving. In this paper authors describe File Carving and present its Literature Survey. The implementation of Greedy Sequential Unique Path File Carving algorithm for 4-bit bitmap files, with the help of function prototypes using C language and brief explanation of these prototypes is explained. The experimental results are also shown. The experimental results show that the files can be reconstructed from their fragments without knowing files" metadata. However there are limitations of these methods as mentioned in section 5.
Repairing the Osteochondral Defect in Goat with the Tissue-Engineered Osteochondral Graft Preconstructed in a Double-Chamber Stirring Bioreactor

To investigate the reparative efficacy of tissue-engineered osteochondral (TEO) graft for repairing the osteochondral defect in goat, we designed a double-chamber stirring bioreactor to construct the bone and cartilage composites simultaneously in one β-TCP scaffold and observed the reparative effect in vivo. The osteochondral defects were created in goats and all the animals were divided into 3 groups randomly. In groups A, the defect was treated with the TEO which was cultured with mechanical stimulation of stir; in group B, the defect was treated with TEO which was cultured without mechanical stimulation of stir; in groups C, the defect was treated without TEO. At 12 weeks and 24 weeks after operation, the reparative effects in different groups were assessed and compared. The results indicated that the reparative effect of the TEO cultured in the bioreactor was better than the control group, and mechanical stimulation of stir could further improve the reparative effect. We provided a feasible and effective method to construct the TEO for treatment of osteochondral defect using autologous BMSCs and the double-chamber bioreactor.
Environmental regulation and international trade patterns for agro-industrial under a South-North Perspective

This paper aims at examining the relation between the international trade and the environment, particularly focused on sensitive agribusiness sectors. It consists on an empirical test to the conflicting positions supported by economists, some following the traditional approach (trade-off or neoclassical), while others supporting the Porter’s hypothesis, which considers that impacts of the stricter environmental regulation can benefit the trade competitiveness. A Heckscher-Ohlin- Vanek model was applied to net exports as the dependent variable. The agricultural products analyzed were total agriculture, rice, maize, soybean, wheat, dairy and swine; run for 97 countries, divided as developing and developed, in a cross-section approach. This modeling allows including the environmental endowment as explanatory variables. Moreover the Environmental Performance Index (Esty et al, 2008) was also tried as explanatory variables in order to catch any effect of the environmental regulation on the trade patterns. Results were not conclusively as they show that the net exports of the selected products, considered environmentally sensitive, can be affected even positively or negatively (neoclassical approach) by the environmental regulation. The results depend on the products. A remarkable outcome to highlight is that the dummy for developing countries and developed countries was significant, pointing that for rice, for example, it makes difference being a developing country, as well as it does for wheat, being a developed country.
Electrocaloric Effect and Phase Transitions in Ferroelectrics

This review summarizes the electrocaloric effect (ECE) and phase transition in terms of the phenomenological theory of ferroelectric materials. Field-induced phase transition can happen in firstorder phase transition materials and some relaxor ferroelectrics under a high enough electric field. The adiabatic temperature change ∆T under a given electric field shows a peak at the ferroelectricparaelectric transition which is agreement with the experimental results. The first-order transition and relaxor ferroelectrics would possess larger ECEs than that in a second-order transition ferroelectrics due to the jump of polarization. This relationship between the phase transition and the electrocaloric effect may be helpful in developing new materials for electrocaloric applications.

Analysis and Visualization of Equilibrium in Masonry Structures by Hijung Valentina Shin

This thesis presents novel analysis and visualization methods to explore the equilibrium of masonry structures. Following a previous approach, we model the stability problem as a quadratic program. When a structure is unstable the quadratic program returns a measure of infeasibility. We extend this model to include tensile structures such as cables. Then, we derive a closed-form gradient of stability with respect to geometry modifications, and apply it to the design of structurally sound buildings. In addition, we analyze various properties related to the equilibrium state of structures and visualize the result. We study the sensitivity of equilibrium with respect to block weights, and from that we trace the flow of forces in the structure. Finally, we compare the equilibrium approach to the finite element analysis (FEA) method-the most widely used alternative. We point out the disadvantage of FEA that comes from formulating the contact constraints and propose an improvement based on an iterative constraint relaxation algorithm.

Signal Processing and Accelerometer-based Design for Portable Small Displacement Measurement Device

A portable accelerometer-based device which used to detect small displacement is designed, and a novel method of acceleration signal processing for small displacement measurement is provided. The system consists of a low-cost tri-axial accelerometer, a microprocessor, and a wireless data transfer module. Accelerometer is sensitive to noise so that it is essential to design a Butterworth low-pass infinite impulse response digital filter for denoising. After signal processing, small displacement calculation method is used to obtain movement detection and estimation. Our experiments show that the method of signal processing for the accelerometer embedded in portable devices is effective, and the portable accelerometer-based device can be used to get small displacement of measured object.
Iterative Action and Pose Recognition Using Global-and-Pose Features and Action-Specific Models

This paper proposes an iterative scheme between human action classification and pose estimation in still images. For initial action classification, we employ global image features that represent a scene (e.g. people, background, and other objects), which can be extracted without any difficult human-region segmentation such as pose estimation. This classification gives us the probability estimates of possible actions in a query image. The probability estimates are used to evaluate the results of pose estimation using action-specific models. The estimated pose is then merged with the global features for action re-classification. This iterative scheme can mutually improve action classification and pose estimation. Experimental results with a public dataset demonstrate the effectiveness of global features for initialization, action-specific models for pose estimation, and action classification with global and pose features.
Relationship between T-SPOT . TB responses and numbers of circulating CD 4 + T-cells in HIV infected patients with active tuberculosis

Tuberculosis (TB) is one of the most common infectious diseases in the world. In 2012, there were an estimated 8.6 million people with active TB. Among these, there were 1.1 million (13%) co-infections with HIV (TBHIV) and 320,000 active TB-HIV deaths according to a report from the World Health Organization (1). Patients with advanced immunodeficiency have a greater risk of active TB (2). Patients with active TB need early diagnosis and prompt treatment. Currently, the gold standard for active TB diagnosis remains the isolation of Mycobacterium tuberculosis positive cultures a procedure that is timeconsuming (3). Also, it is sometimes difficult to obtain suitable culture specimens other than sputum in HIVinfected patients suffering from extrapulmonary TB (4,5). Furthermore, M. tuberculosis culturing is often not available in some regions, and a Ziehl-Neelsen stain may take more than 10 days. There is a great need for new methods for diagnosing TB in HIV-infected subjects throughout the world, especially for patients with advanced immunodeficiency. The introduction of an interferon (IFN)-γ release assay (IGRAs) using the immunogenic and specific M. tuberculosis antigens early secreted antigenic target (ESAT-6) and culture Summary This study sought to evaluate the performance of the T-SPOT.TB assay for the diagnosis of active tuberculosis (TB) in human immunodeficiency virus (HIV) infected patients. One hundred confirmed HIV-infected patients with active TB and known T-SPOT.TB and CD4+ T-cell counts were enrolled in this clinical retrospective study. We found that patients with lower CD4+ T-cell counts (11-50 cells/μL) had the lowest T-SPOT.TB positive rates (50%), and patients with higher CD4+ T-cell counts (50-100 cells/μL) had the highest T-SPOT.TB positive rates (75%). However, there were no significant differences between the T-SPOT.TB positive rates of patients with different CD4+ T-cell counts (< 10, 11-50, 51-100 and > 100 cells/ μL) (χ = 3.7747, p = 0.287). The patients with positive TB culture results had significantly higher T-SPOT.TB positive rates (78.9%) than patients that were culture-negative (44.3%) (χ = 12.8303, p < 0.001). Other variables, including gender, age, TB disease classification, HIV RNA level, and highly reactive antiretroviral therapy (HAART), had no significant effects on T-SPOT.TB positive rates. The number of spot-forming cells (SFCs) reactive with ESAT-6, CFP-10 and ESAT-6/CFP-10-specific T cells detected by T-SPOT.TB were positively correlated with the number of circulating CD4+ T-cells (rs = 0.3791, p = 0.0001; rs = 0.2929, p = 0.0031; rs = 0.3345, p = 0.0007, respectively). This study suggests that the number of SFCs is strongly related to the degree of immunodeficiency, while the T-SPOT.TB positive rates are less dependent on the level of CD4+ T-cell depletion in HIV infection and active TB.
Soil Microbe Active Community Composition and Capability of Responding to Litter Addition after 12 Years of No Inputs

ABSTRACT One explanation given for the high microbial diversity found in soils is that they contain a large inactive biomass that is able to persist in soils for long periods of time. This persistent microbial fraction may help to buffer the functionality of the soil community during times of low nutrients by providing a reservoir of specialized functions that can be reactivated when conditions improve. A study was designed to test the hypothesis: in soils lacking fresh root or detrital inputs, microbial community composition may persist relatively unchanged. Upon addition of new inputs, this community will be stimulated to grow and break down litter similarly to control soils. Soils from two of the Detrital Input and Removal Treatments (DIRT) at the H. J. Andrews Experimental Forest, the no-input and control treatment plots, were used in a microcosm experiment where Douglas-fir needles were added to soils. After 3 and 151 days of incubation, soil microbial DNA and RNA was extracted and characterized using quantitative PCR (qPCR) and 454 pyrosequencing. The abundance of 16S and 28S gene copies and RNA copies did not vary with soil type or amendment; however, treatment differences were observed in the abundance of archaeal ammonia-oxidizing amoA gene abundance. Analysis of ∼110,000 bacterial sequences showed a significant change in the active (RNA-based) community between day 3 and day 151, but microbial composition was similar between soil types. These results show that even after 12 years of plant litter exclusion, the legacy of community composition was well buffered against a dramatic disturbance.
Mean-field electrodynamics: critical analysis of various analytical approaches to the mean electromotive force

There are various analytical approaches to the mean electromotive force crucial in mean-field electrodynamics, with u and b being velocity and magnetic field fluctuations. In most cases the traditional approach, restricted to the second-order correlation approximation, has been used. Its validity is only guaranteed for a range of conditions, which is narrow in view of many applications, e.g., in astrophysics. With the intention to have a wider range of applicability, other approaches have been proposed which make use of the so-called τ-approximation, reducing correlations of third order in u and b to such of second order. After explaining some basic features of the traditional approach a critical analysis of the approaches of that kind is given. It is shown that they lead in some cases to results which are in clear conflict with those of the traditional approach. It is argued that this indicates shortcomings of the τ-approaches and poses serious restrictions to their applicability. These shortcomings do not result from the basic assumption of the τ-approximation. Instead, they seem to originate in some simplifications made in order to derive without really solving the equations governing u and b. A starting point for a new approach is described which avoids the conflict.
Numerical Solution of the Time-Dependent Schrödinger Equation in Ultrafast Laser Dynamics

The numerical approximation of the solution of the time-dependent Schr ödinger equation arising in ultrafast laser dynamics is discussed. The linear Schr ödinger equation is reduced to a computationally tractable, lower dimensional system of nonlinear partial differential equations by the multi-configuration time-dependent Hartree-Fock method . This method serves to approximate the original wave function on a nonlinear manifold, using the antisymmetry inherent in the model to significantly reduce the dimension of the solution space. For the solution of the resulting systems of PDEs, several numerical techniques are compared. Space discretization using the pseudospectral method turns out to be superior to finite difference approximations. For time integration, the range of applicability and computational efficiency of high-order Runge-Kutta methods are compared with variational splitting, a method recently proposed for quantum molecular dynamics. Key-Words: Time-dependent Schr ödinger equation, multi-configuration time-dependent Hartree-Fock method, variational splitting, pseudospectral method.
