The MobiFall Dataset: Fall Detection and Classification with a Smartphone

Fall detection is receiving significant attention in the field of preventive medicine, wellness management and assisted living, especially for the elderly. As a result, several fall detection systems are reported in the research literature or exist as commercial systems. Most of them use accelerometers and/ or gyroscopes attached on a person’s body as the primary signal sources. These systems use either discrete sensors as part of a product designed specifically for this task or sensors that are embedded in mobile devices such as smartphones. The latter approach has the advantage of offering well tested and widely available communication services, e.g. for calling emergency when necessary. Nevertheless, automatic fall detection continues to present significant challenges, with the recognition of the type of fall being the most critical. The aim of this work is to introduce a human fall and activity dataset to be used in testing new detection methods, as well as performing objective comparisons between different reported algorithms for fall detection and activity recognition, based on inertial-sensor data from smartphones. The dataset contains signals recorded from the accelerometer and gyroscope sensors of a latest technology smartphone for four different types of falls and nine different activities of daily living. Utilizing this dataset, the results of an elaborate evaluation of machine learning-based fall detection and fall classification are presented and discussed in detail.

OpenNetVM: Flexible, high performance NFV (Demo)

Network Function Virtualization promises to enable dynamic management of software-based network functions. We envision a dynamic and flexible network that can support a smarter data plane than just simple switches that forward packets. This network architecture supports complex stateful routing of flows where processing by network functions (NFs) can transform packet data, customized on a per-flow basis, as it moves between end points. This demo will present OpenNetVM, a highly efficient packet processing framework that greatly simplifies the development of network functions, as well as their management and optimization. OpenNetVM runs network functions in lightweight Docker containers that start in less than a second. The OpenNetVM platform manager provides load balancing, flexible flow management, and service name abstractions. OpenNetVM uses DPDK for high performance I/O, and efficiently routes packets through dynamically created service chains. We will demonstrate how the research community can easily build new network functions and rapidly deploy them to see their effectiveness in high performance network environments.
The Cancer Coping Questionnaire: A self‐rating scale for measuring the impact of adjuvant psychological therapy on coping behaviour

The Cancer Coping Questionnaire is a brief, self‐rating scale designed to measure coping strategies taught in Adjuvant Psychological Therapy. This paper describes the development of the 21 item Cancer Coping Questionnaire (CCQ) in a sample of 201 patients with mixed cancers. The construct validity and reliability of the instrument are reported from work on 3 samples (a mixed cancer group, n=42; women with breast cancer, n=50; and a group of patients referred for psychological help, n=48). The CCQ showed very good internal reliability and test–retest reliability. As hypothesised cancer patients with more psychological morbidity demonstrated lower CCQ scores, and the CCQ correlated with measures of adjustment to cancer. Compared with an established coping inventory (the Coping Responses Indices; CRI) the CCQs overall individual scale (items 1–14) assessed similar coping areas, particularly in relation to the CRIs foci of coping. The CCQ correlated with Active Behavioural Coping methods on the CRI. The study did not demonstrate sufficiently consistent results concerning the Interpersonal Scale of the CCQ to confirm its validity. Further psychometric work is needed, but the study demonstrated the reliability and validity of the CCQ, supporting the view that change in CCQ scores with cognitive therapy indicates improvement in coping.

Central Limit Theorem for Nonlinear Hawkes Processes

The Hawkes process is a self-exciting point process with clustering effect whose intensity depends on its entire past history. It has wide applications in neuroscience, finance, and many other fields. In this paper we obtain a functional central limit theorem for the nonlinear Hawkes process. Under the same assumptions, we also obtain a Strassen's invariance principle, i.e. a functional law of the iterated logarithm.
Biogenesis of the polymeric IgA receptor in rat hepatocytes. II. Localization of its intracellular forms by cell fractionation studies

In the companion paper (Sztul, E. S., K. E. Howell, and G. E. Palade, J. Cell Biol., 100:1248-1254), we have shown that pulse labeling of hepatic proteins with [35S]cysteine can be obtained in vivo in intact rats. Soluble label clears the plasma in approximately 5 min, and incorporated label reaches peak values in the liver approximately 20 min after injection. In the present study, we show that the 105,000-mol- wt protein (105K), kinetically the earliest intracellular form of secretory component (SC), is the predominant form found, between 5 and 20 min postinjection, in homogeneous rough microsomal fractions. The second kinetically defined form, i.e., 116K, is the predominant species present in relatively homogeneous, light Golgi fractions in which it appears at approximately 15 min, and peaks at approximately 25 min, postinjection. The third kinetically defined form, 120K, is found 30 min after injection as the major SC species (albeit still accompanied by its immediate precursor, 116K), in a sinusoidal plasmalemmal fraction isolated by immunoadsorption to anti-SC-coated Sepharose beads. These findings lead to the following conclusions: (a) SC is synthesized on polysomes attached to the rough endoplasmic reticulum (ER) membrane; (b) it is partially translocated across the ER membrane and core glycosylated co-translationally to give a 105K peptide; (c) 105K moves from the ER to the Golgi complex where it is terminally glycosylated to give the 116K form; (d) the latter moves to the sinusoidal plasmalemma where it appears together with the final mature form, 120K. Kinetic evidence indicates that the vesicular carriers involved in the transport of SC from the Golgi complex to the sinusoidal plasmalemma, and from the latter to the biliary front of the hepatocytes, are present in a Golgi heavy fraction and a crude carrier vesicle fraction from which they remain to be isolated, purified, and characterized.
Good and Bad in the Hands of Politicians: Spontaneous Gestures during Positive and Negative Speech

BACKGROUND According to the body-specificity hypothesis, people with different bodily characteristics should form correspondingly different mental representations, even in highly abstract conceptual domains. In a previous test of this proposal, right- and left-handers were found to associate positive ideas like intelligence, attractiveness, and honesty with their dominant side and negative ideas with their non-dominant side. The goal of the present study was to determine whether 'body-specific' associations of space and valence can be observed beyond the laboratory in spontaneous behavior, and whether these implicit associations have visible consequences. METHODOLOGY AND PRINCIPAL FINDINGS We analyzed speech and gesture (3012 spoken clauses, 1747 gestures) from the final debates of the 2004 and 2008 US presidential elections, which involved two right-handers (Kerry, Bush) and two left-handers (Obama, McCain). Blind, independent coding of speech and gesture allowed objective hypothesis testing. Right- and left-handed candidates showed contrasting associations between gesture and speech. In both of the left-handed candidates, left-hand gestures were associated more strongly with positive-valence clauses and right-hand gestures with negative-valence clauses; the opposite pattern was found in both right-handed candidates. CONCLUSIONS Speakers associate positive messages more strongly with dominant hand gestures and negative messages with non-dominant hand gestures, revealing a hidden link between action and emotion. This pattern cannot be explained by conventions in language or culture, which associate 'good' with 'right' but not with 'left'; rather, results support and extend the body-specificity hypothesis. Furthermore, results suggest that the hand speakers use to gesture may have unexpected (and probably unintended) communicative value, providing the listener with a subtle index of how the speaker feels about the content of the co-occurring speech.
Women, Marriage, and Selfhood: How Names impact upon Gendered Identity

In Britain the naming norm of one name within a family continues to hold powerful sway. Women change their names to that of their husband in large numbers (Valetas, 2001: 2) and the expectation that they will do so remains, despite women’s changing position within society. This, set within the context of individualisation and sociological ideas of the ‘pure relationship’ (Giddens, 1996: 6) and less commitment from couples (Bauman, 2003: 34), may seem anachronistic, yet the popularity of the name change remains. My aim in this thesis is to investigate what women in Britain do with their last names on marriage (name changing and name retaining) and how this impacts upon their sense of gendered identity. I explore the ideas raised by the individualisation theorists in relation to these naming decisions to assess their relevance for the actualities of women’s lives. I also analyse love, commitment, family ties, and explore narratives of selfhood and accountability. The empirical work took the form of an open and closed question online survey, responded to by 102 women (75 changed names and 27 retained names), and 16 in-depth interviews. I asked for British, heterosexual women to take part to explore the institution of marriage, within one cultural setting. Though name changing has a historical connection with women as lesser than men and as property given through marriage, this history was rarely mentioned by name changing participants who focus instead on love, unity, creating a family, and creative and adaptable selfhood to justify their actions. Those women who retain their names focus on linear selfhood, feminism, work, and the private nature of marriage. Justifying one’s actions is generally the preserve of the ‘deviant’ (Scott and Lyman, 1968: 62) and the disparity between those who must account and those who must not will be explored.
AAS 16-236 PROBABILISTIC INITIAL ORBIT DETERMINATION

Future space surveillance requires dealing with uncertainties directly in the initial orbit determination phase. We propose an approach based on Taylor differential algebra to both solve the initial orbit determination (IOD) problem and to map uncertainties from the observables space into the orbital elements space. This is achieved by approximating in Taylor series the general formula for pdf mapping through nonlinear transformations. In this way the mapping is obtained in an elegant and general fashion. The proposed approach is applied to both anglesonly and two position vectors IOD for objects in LEO and GEO.
Abstract Representations of Associated Emotions in the Human Brain

Emotions can be aroused by various kinds of stimulus modalities. Recent neuroimaging studies indicate that several brain regions represent emotions at an abstract level, i.e., independently from the sensory cues from which they are perceived (e.g., face, body, or voice stimuli). If emotions are indeed represented at such an abstract level, then these abstract representations should also be activated by the memory of an emotional event. We tested this hypothesis by asking human participants to learn associations between emotional stimuli (videos of faces or bodies) and non-emotional stimuli (fractals). After successful learning, fMRI signals were recorded during the presentations of emotional stimuli and emotion-associated fractals. We tested whether emotions could be decoded from fMRI signals evoked by the fractal stimuli using a classifier trained on the responses to the emotional stimuli (and vice versa). This was implemented as a whole-brain searchlight, multivoxel activation pattern analysis, which revealed successful emotion decoding in four brain regions: posterior cingulate cortex (PCC), precuneus, MPFC, and angular gyrus. The same analysis run only on responses to emotional stimuli revealed clusters in PCC, precuneus, and MPFC. Multidimensional scaling analysis of the activation patterns revealed clear clustering of responses by emotion across stimulus types. Our results suggest that PCC, precuneus, and MPFC contain representations of emotions that can be evoked by stimuli that carry emotional information themselves or by stimuli that evoke memories of emotional stimuli, while angular gyrus is more likely to take part in emotional memory retrieval.
Mathematical models and simulation of Costas loops

Yuldashev, Marat Mathematical Models and Simulation of Costas Loops Jyvaskyla: University of Jyvaskyla, 2013, 72 p.(+included articles) (Jyvaskyla Studies in Computing ISSN 1456-5390; 174) ISBN 978-951-39-5488-8 (nid.) ISBN 978-951-39-5491-8 (PDF) Finnish summary Diss. This work is devoted to the development of nonlinear mathematical models of Costas loops. A Costas loop was invented in 1956 by John P. Costas of General Electric. Nowadays, a Costas loop is widely used in many applications including telecommunication devices, global positioning systems (GPS), medical implants, mobile phones, and other gadgets. Costas loop is a phase-locked loop (PLL) based circuit designed to simultaneously perform two tasks — carrier recovery and data demodulation. To performs both of these tasks it has three non-linear elements. So, Costas loop is more complicated circuit than analog PLLs with only one nonlinear element and therefore requires special techniques for its analysis. All this makes the development of non-linear models of Costas loops a difficult task. For high-frequency signals, used in the modern devices, the transient time is thousands of times greater than the signal’s periods. This property of Costas loop further complicates the application of analytical methods and numerical simulation. Also the signal waveforms involved greatly affect the behaviour of Costas circuits. In this work, nonlinear mathematical models of the BPSK Costas loop and the Quadrature Phase Shift Keying (QPSK) Costas loop have been developed. These models allow to facilitate the application of analytical methods and reduce the numerical simulation time, which is a practically relevant significant problem. All theoretical results are rigorously proved. An effective numerical procedure for the simulation of Costas loops based on the phase-detector characteristics is proposed.
Sufficient conditions for complexity reduction in min-max control of constrained uncertain linear systems

In this paper we consider finite-time min-max optimization problems for linear systems with additive disturbances subject to hard input constraints and soft state constraints. We present a set of state-dependent sufficient conditions which allow for the efficient solution of the min-max optimization problem. The set of initial states for which the proposed conditions are satisfied is computed by solving a sequence of linear programs. We compare the proposed method to open-loop, vertex enumeration, and affine disturbance feedback techniques in terms of computational complexity and optimal cost using a simple example. We also demonstrate the efficacy of the approach in predictive control design for radiant-slab cooling systems.

Adaptive Spatial Intercell Interference Cancellation in Multicell Wireless Networks

Downlink spatial intercell interference cancellation (ICIC) is considered for mitigating other-cell interference using multiple transmit antennas. A principle question we explore is whether it is better to do ICIC or simply standard single-cell beamforming. We explore this question analytically and show that beamforming is preferred for all users when the edge SNR (signal-to-noise ratio) is low (<;0 dB), and ICIC is preferred when the edge SNR is high (>10 dB), for example in an urban setting. At medium SNR, a proposed adaptive strategy, where multiple base stations jointly select transmission strategies based on the user location, outperforms both while requiring a lower feedback rate than the pure ICIC approach. The employed metric is sum rate, which is normally a dubious metric for cellular systems, but surprisingly we show that even with this reward function the adaptive strategy also improves fairness. When the channel information is provided by limited feedback, the impact of the induced quantization error is also investigated. The analysis provides insights on the feedback design, and it is shown that ICIC with well-designed feedback strategies still provides significant throughput gain.
Clinical Supervision in Social Work

Abstract In social work, supervision is valued as a crucial activity for professional learning and development. Over time, an extensive body of literature has developed that is largely theoretical and practice-oriented. The development of an empirical body of knowledge for supervision has been slow with most approaches supported solely by anecdotal accounts. An extensive review of the empirical studies on supervision conducted in the past decade was undertaken. Two separate streams of inquiry were found; one focused on supervision of professional staff and one focused on field education of students. This body of research is reviewed in two companion papers. Recent studies of supervision of staff are largely descriptive and exploratory yielding limited knowledge for evidence-based supervision. Organizational and professional issues related to the dearth of studies are discussed.
Reproducibility of nerve fiber thickness, macular thickness, and optic nerve head measurements using StratusOCT.

PURPOSE The measurement reproducibility of the third generation of commercial optical coherence tomography, OCT-3 (StratusOCT, software ver. A2, Carl Zeiss Meditec Inc., Dublin, CA) was investigated. The nerve fiber layer (NFL) thickness, macula thickness map, and optic nerve head (ONH) parameters in normal eyes were studied. METHODS Ten normal subjects were imaged six times (three before and three after dilation) per day, and the series was repeated on three different days. The order of the scans before pupil dilation was randomized in each of the 3 days of scanning. After pupil dilation, the scans were also randomized in each of the 3 days of scanning. Each series was performed separately for standard-density (128 A-scans per macular and ONH image and 256 A-scans per NFL image) and high-density (512 A-scans per image for all three scan types) scanning. RESULTS The mean macular thickness was 235 +/- 9.8 micro m. A-scan density (or image acquisition speed) had a statistically significant effect (P < 0.05) on the reproducibility of the mean macular thickness, macular volume, and a few sectors of the macular map. No significant dilation effect was found for any of the macular parameters. The best intraclass correlation coefficient (ICC; 94%) for macular scans was found for dilated high-density scanning, with an intervisit SD of 2.4 micro m and an intravisit SD of 2.2 micro m. The mean NFL thickness for standard scanning was 98 +/- 9 micro m. NFL reproducibility showed mixed results and had interactions between scan density and dilation for some parameters. For most of the NFL parameters, reproducibility was better with dilated standard-density scanning. The mean NFL thickness ICC for dilated standard scanning was 79%, with an intervisit SD of 2.5 micro m and an intravisit SD of 1.6 micro m. For the ONH analysis, the reproducibility was better for dilated standard-density scanning for almost all the parameters, except for disc area, horizontal integrated rim volume, and vertical integrated rim area, which were better before dilation. The best reproducibility was found for cup-to-disc ratio (ICC = 97%, with intervisit SD of 0.04 micro m and intravisit SD of 0.02 micro m). CONCLUSIONS StratusOCT demonstrated reproducible measurements of NFL thickness, macular thickness, and optic nerve head parameters. The best reproducibility was found for dilated standard scanning for NFL and ONH parameters and for dilated high-density scanning for macular parameters.
The DoF Region of the Three-Receiver Gaussian MIMO Broadcast Channel With Receiver Message Side Information

We consider the three-receiver Gaussian multiple-input multiple-output broadcast channel with an arbitrary number of antennas at the transmitter and the receivers. We investigate the degrees-of-freedom (DoF) region of the channel when each receiver requests a private message, and may know some of the messages requested by the other receivers as receiver message side information (RMSI). We establish the DoF region of the channel for all 16 possible non-isomorphic RMSI configurations by deriving tight inner and outer bounds on the region. To derive the inner bounds, we first propose a scheme for each RMSI configuration, which exploits both the null space and the side information of the receivers. We then use these schemes in conjunction with time sharing for 15 RMSI configurations, and with time sharing and two-symbol extension for the remaining one. To derive the outer bounds, we construct enhanced versions of the channel for each RMSI configuration, and upper bound their DoF region. After establishing the DoF region, in the case where all the nodes have the same number of antennas, we introduce some common properties of the DoF region, and the capacity region of the index coding problem.
