Energy-optimal dynamic voltage scaling in multicore platforms with reconfigurable power distribution network

This work addresses a new problem of dynamic voltage scaling (DVS) in multicore platforms. We solve the multicore DVS problem, i.e., simultaneously scheduling execution of tasks assigned to cores and determining dynamically-varying voltage levels, with the objective of minimizing total energy consumption of the cores and voltage regulators (VRs) in the reconfigurable VR-to-core power distribution network (PDN) of platform while meeting the arrival/deadline constraint of tasks. Here, the key factors to be exploited for energy saving are (1) available voltage levels, (2) power conversion efficiency curve of VRs, and (3) turning on/off VRs. Specifically, we formulate the problem of task scheduling with the relation between factors 1, 2, and 3 into a linear programming problem and solve optimally in polynomial time.
A bridging domain and strain computation method for coupled atomistic–continuum modelling of solids

We present a multiscale method that couples atomistic models with continuum mechanics. The method is based on an overlapping domain‐decomposition scheme. Constraints are imposed by a Lagrange multiplier method to enforce displacement compatibility in the overlapping subdomain in which atomistic and continuum representations overlap. An efficient version of the method is developed for cases where the continuum can be modelled as a linear elastic material. An iterative scheme is utilized to optimize the coupled configuration. Conditions for the regularity of the constrained matrices are determined. A method for computing strain in atomistic models and handshake domains is formulated based on a moving least‐square approximation which includes both extensional and angle‐bending terms. It is shown that this method exactly computes the linear strain field. Applications to the fracture of defected single‐layer atomic sheets and nanotubes are given.

Short-Pulsed Wavepacket Propagation in Ray-Chaotic Enclosures

Wave propagation in ray-chaotic scenarios, characterized by exponential sensitivity to ray-launching conditions, is a topic of significant interest, with deep phenomenological implications and important applications, ranging from optical components and devices to time-reversal focusing/sensing schemes. Against a background of available results that are largely focused on the time-harmonic regime, we deal here with short-pulsed wavepacket propagation in a ray-chaotic enclosure. For this regime, we propose a rigorous analytical framework based on a short-pulsed random-plane-wave statistical representation, and check its predictions against the results from finite-difference-time-domain numerical simulations.
The Child PTSD Symptom Scale: an update and replication of its psychometric properties.

The psychometric properties of the child PTSD Symptom Scale (CPSS) were examined in 2 samples. Sample 1 (N = 185, ages 6-17 years) consisted of children recruited from hospitals after accidental injury, assault, and road traffic trauma, and assessed 6 months posttrauma. Sample 2 (N = 68, ages 6-17 years) comprised treatment-seeking children who had experienced diverse traumas. In both samples psychometric properties were generally good to very good (internal reliability for total CPSS scores = .83 and .90, respectively). The point-biserial correlation of the CPSS with posttraumatic stress disorder (PTSD) diagnosis derived from structured clinical interview was . 51, and children diagnosed with PTSD reported significantly higher symptoms than non-PTSD children. The CPSS demonstrated applicability to be used as a diagnostic measure, demonstrating sensitivity of 84% and specificity of 72%. The performance of the CPSS Symptom Severity Scale to accurately identify PTSD at varying cutoffs is reported in both samples, with a score of 16 or above suggested as a revised cutoff.
Phagocytic response of astrocytes to damaged neighboring cells

This study aims to understand the phagocytic response of astrocytes to the injury of neurons or other astrocytes at the single cell level. Laser nanosurgery was used to damage individual cells in both primary mouse cortical astrocytes and an established astrocyte cell line. In both cases, the release of material/substances from laser-irradiated astrocytes or neurons induced a phagocytic response in near-by astrocytes. Propidium iodide stained DNA originating from irradiated cells was visible in vesicles of neighboring cells, confirming phagocytosis of material from damaged cortical cells. In the presence of an intracellular pH indicator dye, newly formed vesicles correspond to acidic pH fluorescence, thus suggesting lysosome bound degradation of cellular debris. Cells with shared membrane connections prior to laser damage had a significantly higher frequency of induced phagocytosis compared to isolated cells with no shared membrane. The increase in phagocytic response of cells with a shared membrane occurred regardless of the extent of shared membrane (a thin filopodial connection vs. a cell cluster with significant shared membrane). In addition to the presence (or lack) of a membrane connection, variation in phagocytic ability was also observed with differences in injury location within the cell and distance separating isolated astrocytes. These results demonstrate the ability of an astrocyte to respond to the damage of a single cell, be it another astrocyte, or a neuron. This single-cell level of analysis results in a better understanding of the role of astrocytes to maintain homeostasis in the CNS, particularly in the sensing and removal of debris in damaged or pathologic nervous tissue.
1 What do we learn from word associations ? Evaluating 2 machine learning algorithms for the extraction of 3 contextual word meaning in natural language 4 processing 5

“You should know the words by the company they keep! ” has been one of the most famous 10 slogans attribute to John Rubert Firth, 1957. This has ignited a whole school in linguistic research 11 known as the British empiricist contextualism. Sixty years later, many unor semi-supervised 12 machine learning algorithms have been successfully designed and implemented aiming at 13 extracting word meaning from within the context of a text corpus. These algorithms treat words, 14 more or less, as vectors of real numbers representing frequencies of word occurrences within context 15 and word meaning as positions of words in a high-dimensional vector space models. Word 16 associations, in turn, are treated as calculated distances among them. With the rise of Deep Learning 17 (DL) and other artificial neural networks based architectures, learning the positioning of words and 18 extracting word associations as measured by their distances has further improved. In this paper, 19 however, we revisited the main stream of algorithmic approaches and set the stage for a partly cross20 disciplinary evaluation framework to judge about the nature of the extracted word associations by 21 state-of-the-art machine learning algorithms. Our preliminary results, which are based on word 22 associations extracted from the application of DL framework on a Google News text corpus, and 23 comparisons with human created word association lists, provide some insights into the inherited 24 limitations in interpreting the type of word associations and underpinning relations between words 25 with inevitable consequences in other areas, such as extraction of knowledge graphs or image 26 understanding. 27
INTIMATE PARTNER VIOLENCE: GENDER SYMMETRY AND THE VICTIM PERPETRATOR OVERLAP

This study addressed substantial limitations in the literature pertaining to intimate partner violence (IPV). In particular, I addressed the gender symmetry debate, and identified factors associated with the dynamics of violent relationships by examining the correlates related to perpetrating and suffering IPV for both men and women. Finally, I examined attitudes towards IPV, communication behaviour, and conflict management techniques as a function of abuse history. Participants were recruited from three samples of the New Zealand population (student, general, and incarcerated). The inclusion of an incarcerated sample enabled the examination of more severe, frequent and injurious violence than is typically experienced within the student and general samples. There were three phases to the study. The first phase explored incidence rates and psychological correlates of IPV. As expected, the incidence of IPV was highest within the incarcerated sample (Chapter 5). Of greater significance, the incidence of IPV was similar for males and females, with the majority of violence being bi- directional (Chapters 4 & 5). Moreover, the psychological correlates associated with IPV were similar for perpetrators and victims, and males and females (Chapters 4 & 5). Due to the bi-directional nature of IPV, analyses presented in Chapters 4 and 5 were limited by the categorisation of participants as both perpetrators and victims. In Chapter 6, I overcame this limitation. The attitudes of victims were examined separately to individuals experiencing bi-directional violence. Validating the findings of Chapters 4 and 5, the attitudes and behaviours of victims and perpetrators were similar. These included being more hostile and negative towards others and ones’
Life-cycle Changes in Modes of Coordination in Wikipedia

We present evidence of explicit and non-explicit coordination (i.e., coordination mediated or not by discussion) in the context of Wikipedia. Using a novel approach to identifying edits to the same part of a Wikipedia article, we show that a majority of edits in a small sample of articles are not associated with discussion on the article Talk page. However, we find that explicit coordination seems related to article quality. Analyzing different modes of coordination over the articles’ life cycle, we show that explicit coordination seems to follow non-explicit in higher quality articles.
A Fully Integrated Class-J GaN MMIC Power Amplifier for 5-GHz WLAN 802.11ax Application

This letter presents a fully integrated Class-J GaN monolithic microwave circuit power amplifier (PA), which is fabricated in Woolfspeed 0.25-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> GaN-on-SiC technology. This PA is the first published design for the emerging IEEE 802.11ax application in the literature. When tested with 80-MHz 256-quadratic-amplitude modulation 802.11ax signal with 11.25-dB peak-to-average power ratio, the PA delivers average output power of 27.3–30.3 dBm from 4.9 to 5.9 GHz, with power-added efficiency of 16.7% to 27.3%, while meeting the standard specification of error vector magnitude below −32 dB.
Asymmetric Ultra-Wideband Microstrip-to-Coplanar Stripline Transition

A new design method for an asymmetric microstrip-to-coplanar stripline (CPS) transition based on the analytical electromagnetic model is presented. The cross section at each stage of the transition is analyzed through conformal transformation, and the corresponding line impedance is calculated. Then, the ground linewidth on the substrate bottom is adjusted to form an optimal Klopfenstein impedance taper. To demonstrate the design method, a transition between a 50-<inline-formula> <tex-math notation="LaTeX">$\Omega $ </tex-math></inline-formula> microstrip line and a high-impedance CPS line (<inline-formula> <tex-math notation="LaTeX">$147~\Omega$ </tex-math></inline-formula>) was implemented. Good transition performance with more than 10-dB return loss and less than 1-dB insertion loss was obtained for frequency ranges of 6–40 GHz.
A model-based parameter estimation approach for numerical analysis of single-mode optical fibers

An efficient numerical method is proposed and implemented for the analysis of propagation characteristics of single-mode optical fibers with arbitrary refractive index profile. The method follows the concept of the so-called model-based parameter estimation, and the Pade algorithm is used to construct a low-order rational approximant of the spectral domain Green's function, obtained by solving a hierarchy of static problems. The sought eigenfrequency and field distribution are then estimated by computing, respectively, the dominant pole and the related residual of the rational approximant. A number of profiles are analyzed and experiments show that very accurate results can be cheaply obtained through this technique.
CLEC10A Is a Specific Marker for Human CD1c+ Dendritic Cells and Enhances Their Toll-Like Receptor 7/8-Induced Cytokine Secretion

Dendritic cells (DCs) are major players for the induction of immune responses. Apart from plasmacytoid DCs (pDCs), human DCs can be categorized into two types of conventional DCs: CD141+ DCs (cDC1) and CD1c+ DCs (cDC2). Defining uniquely expressed surface markers on human immune cells is not only important for the identification of DC subpopulations but also a prerequisite for harnessing the DC subset-specific potential in immunomodulatory approaches, such as antibody-mediated antigen targeting. Although others identified CLEC9A as a specific endocytic receptor for CD141+ DCs, such a receptor for CD1c+ DCs has not been discovered, yet. By performing transcriptomic and flow cytometric analyses on human DC subpopulations from different lymphohematopoietic tissues, we identified CLEC10A (CD301, macrophage galactose-type C-type lectin) as a specific marker for human CD1c+ DCs. We further demonstrate that CLEC10A rapidly internalizes into human CD1c+ DCs upon binding of a monoclonal antibody directed against CLEC10A. The binding of a CLEC10A-specific bivalent ligand (the MUC-1 peptide glycosylated with N-acetylgalactosamine) is limited to CD1c+ DCs and enhances the cytokine secretion (namely TNFα, IL-8, and IL-10) induced by TLR 7/8 stimulation. Thus, CLEC10A represents not only a candidate to better define CD1c+ DCs—due to its high endocytic potential—CLEC10A also exhibits an interesting candidate receptor for future antigen-targeting approaches.
Revisiting the Relationship Between Acculturation and Smoking Cessation Among Mexican Americans.

BACKGROUND A well-established gender-differentiated association between acculturation and current smoking exists among Latino adults. There are far fewer studies on the potential influence of acculturation on smoking cessation, and extant findings are mixed. PURPOSE Using a multidimensional measure of acculturation, the current study examined the independent and interactive associations of gender and acculturation with smoking cessation among Mexican American smokers engaged in a quit attempt. METHODS Using a latent variable modeling approach to repeated measures analysis, the independent and interaction effects of acculturation in two cultural directions (American and Mexican) were examined for their prospective associations with smoking abstinence. Interactions of acculturation domains with gender were also examined. Acculturation was assessed at baseline and abstinence status was assessed at 3 and 26 weeks post-quit. RESULTS The interaction of American and Mexican cultural identity was significantly associated with smoking abstinence, such that greater American cultural identity was positively associated with abstinence only among those with high Mexican cultural identity. The interaction of English proficiency with gender was significant such that English proficiency was positively associated with abstinence among men but not women. CONCLUSIONS Findings in the cultural identity domain are consistent with a "benefits of biculturalism" perspective, and may be particularly relevant to the adoption of an American cultural orientation among persons with an already-strong heritage-culture orientation. Findings also replicate a gender-differentiated association between acculturation and cessation. Implications for treatment development and future research are discussed.
Simultaneous Robot-World, Sensor-Tip, and Kinematics Calibration of an Underactuated Robotic Hand With Soft Fingers

Soft robotics is a research field growing rapidly with primary focuses on the prototype design, development of soft robots and their applications. Due to their highly deformable features, it is difficult to model and control such robots in a very precise way compared with the conventional rigid structured robots. Hence, the calibration and parameter identification problems of an underactuated robotic hand with soft fingers are important, but have not been investigated intensively. In this paper, we present a comparative study on the calibration of a soft robotic hand. The calibration problem is framed as an <inline-formula> <tex-math notation="LaTeX">$AX = YB$ </tex-math></inline-formula> problem with the partially known matrix <inline-formula> <tex-math notation="LaTeX">$A$ </tex-math></inline-formula>. The identifiability of the parameters is analyzed, and calibration methods based on nonlinear optimization (i.e., Levenberg–Marquardt method and interior-point method) and evolutionary computation (i.e., differential evolution) are presented. Extensive simulation tests are performed to examine the parameter identification using the three methods in a comparative way. The experiments are conducted on the real soft robotic-hand setup. The fitting, interpolating, and extrapolating errors are presented as well.
Relationships of isometric mid-thigh pull variables to weightlifting performance.

AIM The purpose of this study was to evaluate the relationship between weightlifting performance (snatch, clean and jerk, and total) and variables obtained from the isometric mid-thigh pull (IMTP). METHODS Twelve weightlifters, ranging from novice to advanced, performed the IMTP 10 days after a competition. Correlations were used to evaluate relationships between variables of the IMTP and absolute and scaled competition results. RESULTS Unscaled competition results correlated strongly with IRFD (0-200ms: r=0.567-0.645, 0-250ms: r=0.722-0.781) while results correlated weakly with Peak IRFD (5ms window, r=0.360-0.426). Absolute peak force values correlated very strongly with absolute values for the competition performance (r=0.830-0.838). Force at 100ms, 150ms, 200ms and 250ms also correlated strongly with competition results (r=0.643-0.647, r=0.605-0.636, r=0.714-0.732, r=0.801-0.804). Similar findings were noted for allometrically scaled values. CONCLUSION Measures of average IRFD probably represent a more relevant variable to dynamic performance than does Peak IRFD (5ms). Maximum isometric strength also is likely to have a strong role in weightlifting performance.

Askin Tumor in Egyptian Patients; 5 Years Experience at the National Cancer Institute, Cairo University

Background: Askin tumor is a primitive neuroectodermal tumor of the Ewing sarcoma family arising from soft tissues of the chest wall. It is the commonest chest wall malignancy in children and adolescents. Its diagnosis is complex and management requires a multidisciplinary work including chemotherapy for systemic disease and radiation therapy to assist local control which is achieved through surgery with or without reconstruction. Objective: To analyze report and understand the clinicopathological features, results and outcome of this tumor with assessment of early and late postoperative complications following resection and chest wall reconstruction. Materials and Methods: This is a retrospective analysis of 30 cases with chest wall ES/PNET presented to the National Cancer Institute; Cairo University between January 2011 and December 2015. All patients’ records were revised for age, sex, clinical presentation, imaging, pathology, operative notes, different treatment modalities given, early and late postoperative complications following surgical resection or reconstruction, and outcome including overall survival (OS) and disease free survival (DFS). Results: Our cohort included 30 patients with chest wall ES. The median follow up period (n = 30) was 33.7 months (ranging from 3.7 to 69.3 months). The median OS was 54.2 months with cumulative OS at 60 months which was 45.6%. The median DFS was 27.9 months with cumulative DFS at 60 months which was 40.6%. All cases were below 18 years with a male predominance (n = 19). The commonest affected sites were ribs (n = 22, 73.3%), the scapula (n = 5, 16.6%), the clavicle (n = 2, 6.66%) and the sternum (n = 1, 3.33%). 23 patients (76.6%) were presented with localized disease, and 7 patients (23.4%) were metastatic from the start. All patients received neoadjuvant chemotherapy (4 cycles of VAC/IE) followed by local control: either surgery (26 cases, 86.6%) or radical radiotherapy (3 cases, 10%). A single case of a rib ES with initial bilateral lung deposited where no local control was done. After chest wall resection, closure of the defect was done by 1 ry closure with no reconstruction or double layer prolene mesh and bone cement that was covered by pedicled flap (latissimus dorsi, serratus anterior or pectoralis major muscle flap). Postoperative radiation therapy was given to 9 patients: 4 (13.3%) had postoperative poor chemotherapy effect (<90% tumor necrosis), 3 (10%) had +ve microscopic safety margin and 2 (6.6%) had pleural based nodules with malignant pleural effusion at initial presentation. Conclusion: Askin’s tumor shows a dramatic response to polychemotherapy. Treatment of such tumor should include multidisciplinary working groups for optimum results and better survival.
Scalable Bandwidth-Tunable Micro-Ring Filter Based on Multi-Channel-Spectrum Combination

We propose and experimentally demonstrate a scalable bandwidth-tunable bandpass filter on silicon. Its spectrum is combined by that of four channels and each channel is formed by two cascaded micro-ring resonators (MRRs). By tuning the center wavelength spacing of the eight MRRs and the phase shifts of four channels, a wide bandwidth tuning range from 37.5 GHz to 227.5 GHz can be achieved with a shape factor between 0.2 and 0.73 and an in-band ripple less than 1 dB. By comparing with the performance of three-channel and two-channel structures, we can draw the conclusion that inducing more channels can effectively improve the bandwidth tunability. The filter also has a wide free spectral range (about 1.2 THz) and small footprint (0.12 mm2).
