Towards Improving Embedding Based Models of Social Network Alignment via Pseudo Anchors

Social network alignment aims at aligning person identities across social networks. Embedding based models have been shown effective for the alignment where the structural proximity preserving objective is typically adopted for the model training. With the observation that “overly-close” user embeddings are unavoidable for such models causing alignment inaccuracy, we propose a novel learning framework which tries to enforce the resulting embeddings to be more widely apart among the users via the introduction of carefully implanted pseudo anchors. We further proposed a meta-learning algorithm to guide the updating of the pseudo anchor embeddings during the learning process. The proposed intervention via the use of pseudo anchors and meta-learning allows the learning framework to be applicable to a wide spectrum of network alignment methods. We have incorporated the proposed learning framework into several state-of-the-art models. Our experimental results demonstrate its efficacy where the methods with the pseudo anchors implanted can outperform their counterparts without pseudo anchors by a fairly large margin, especially when there only exist very few labeled anchors.
Octonion Short-Time Fourier Transform for Time-Frequency Representation and Its Applications

The octonion Fourier transform (OFT) is a useful tool for signal processing and analysis. However, due to the lack of time localization information, it is not suitable for processing signals whose frequencies vary with time. In this paper, we utilize octonion algebra to propose a new method for time-frequency representation (TFR) called the octonion short-time Fourier transform (OSTFT). The originality of the method is based on the quaternion short-time Fourier transform (QSTFT). First, we generalize the QSTFT to the OSTFT by substituting the quaternion kernel function with the octonion kernel function in the definition of the QSTFT, and the physical significance of the OSTFT is presented. Then, several essential properties of the OSTFT are derived, such as linearity, inversion formulas, time-frequency shifts and orthogonality relations. Based on the classic Fourier convolution operation, the convolution theorem for the OSTFT is derived. We apply the relationship between the OFT and OSTFT to establish Pitt's inequality and Lieb's inequality for the OSTFT. According to the logarithmic uncertainty principle of the OFT, the logarithmic uncertainty principle associated with the OSTFT is investigated. Finally, an application in which OSTFT can be used to study linear time varying (LTV) systems is proposed, and some potential applications of the OSTFT are introduced.
On the effect of possible reflections at the return stroke wavefront on radiated fields from lightning strikes to tall structures

An extension of the engineering return-stroke models for lightning strikes to tall structures that takes into account the presence of possible reflections at the returnstroke (RS) wavefront and the presence of an upward leader is presented. Closed-form, iterative solutions for the current distribution along the channel and the strike object are derived. By setting the value of the reflection coefficient to -1 at the return-stroke wavefront, the current at that location is forced to zero, avoiding thereby a discontinuity. Simulation results for the electromagnetic fields generated by RS current of lightning strikes to the CN Tower (553 m) are presented. It is shown that taking into account the reflections at the return-stroke wavefront results in fine structure in the field's late-time response. Moreover, the obtained results are in better agreement with experimental observations, reproducing both the early narrow undershoot and the far-field zero crossing.
Seasonal contrasts between tropical cyclone genesis in the South China Sea and westernmost North Pacific

Climatologically, tropical cyclone (TC) genesis in the South China Sea (SCS; 108°–120°E, 8°–22°N) and westernmost North Pacific (WmNP; 122°–140°E, 8°–22°N) exhibit different seasonal variability. Maximum TC genesis occurs in July over the WmNP, but in September over the SCS. Based upon genesis potential index (GPI) analysis for the period 1979–2018, the dominant cause of increased TC genesis in the SCS from July to September is a reduction of vertical wind shear of total winds (VWS), while decreased 600‐hPa relative humidity (RH600) acts to suppress TC genesis. Reduced VWS in the SCS is associated with weakening of southwesterly flows and cross‐equatorial southerly flows at 850 hPa and the Tibetan high at 200 hPa. In the WmNP, decreased TC genesis from July to September results from a minor increase in its northern section (north of 15°N) and a major decrease in its southern section (south of 15°N). Decreased TC genesis in the southern section is primarily affected by reduced RH600 and secondly by enhanced VWS. Reduced RH600 is associated with a decrease in total humidity and an increase in 600‐hPa temperature from July to September. Enhanced VWS is mainly caused by intensified entrances of 850‐hPa westerly/southwesterly flows from the SCS and cross‐equatorial flows from tropical oceans in company with weakening of the Pacific subtropical high. The effects of 850‐hPa absolute vorticity and potential intensity associated with the possible maximum wind speed on seasonal variability of TC genesis are insignificant and minor.
Beyond Imitation, Without Limitations: A Student Music Therapist Supports the Participation and Development of Young People with Profound and Multiple Learning Difficulties in a School Setting

This exploratory study sought to uncover the methods and techniques a student music therapist employed to support the participation of young people with complex needs in a school setting. Individual music therapy sessions were carried out over nine months, and clinical documentation was generated throughout this period. Data sources included clinical notes, a reflective journal, and audiovisual recordings from music therapy sessions. Once a research question had been established, the existing data was reviewed retrospectively through a process of secondary analysis, and both inductive and deductive methods of analysis were employed to enable meaningful interpretations of the data to occur. A process of coding and thematically linking elements of music therapy practice allowed for a model of understanding to emerge, and findings suggest that the behaviours and strategies utilised by the student music therapist to support the young people’s participation in music therapy fell into three thematic groupings: creating a collaborative environment; following and leading; and dynamic flow. Themes are defined and the codes within elaborated upon, with case examples from the data included as appropriate to illustrate their meaning. Findings are discussed, and links are made to the literature in relevant fields. While results cannot be generalised to other settings, it is hoped that the detail and in depth analysis of practice provide a thorough and meaningful insight into the types of interaction that can occur in music therapy with young people with complex needs, and the value of specific supports to participation identified in this research.
Recurrent neural circuits overcome partial inactivation by compensation and re-learning

Technical advances in artificial manipulation of neural activity have precipitated a surge in studying the causal contribution of brain circuits to cognition and behavior. However, complexities of neural circuits challenge interpretation of experimental results, necessitating theoretical frameworks for system-atic explorations. Here, we take a step in this direction, using, as a testbed, recurrent neural networks trained to perform a perceptual decision. We show that understanding the computations implemented by network dynamics enables predicting the magnitude of perturbation effects based on changes in the network’s phase plane. Inactivation effects are weaker for distributed network architectures, are more easily discovered with non-discrete behavioral readouts (e.g., reaction times), and vary considerably across multiple tasks implemented by the same circuit. Finally, networks that can “learn” during inactivation recover function quickly, often much faster than the original training time. Our framework explains past empirical observations by clarifying how complex circuits compensate and adapt to perturbations.
Personal Identification Using Finger-Knuckle-Print Based on Local Binary Pattern

Over the last ten years, considerable progress has been made on the new hand-based biometric recognition, such as palmprint and hand vein. During this period, it has been proved that Finger-Knuckle-Print (FKP) can be used as a biometric identifier. In this paper, we present an effective FKP identification method based on Local Binary Pattern (LBP), whose idea is to divide the region of interest (ROI) of FKP into a set of sub-image blocks, which can be applied to extract the local features of the FKP. After that, LBP histograms of image blocks in a FKP ROI image are connected together to build the feature vector of the FKP ROI image. In the match stage, histogram intersection distance is applied as the similarity measurement between sample and template. Experimental results conducted on a database of 165 persons (4 fingers per person) show that the proposed method is effective.
Rainfall and Temperature Trends in Jagtial District of Telangana State

Aims: To investigate and assess the significance of the potential trend of two variables viz. rainfall, temperature in Jagtial district of Telangana state. Place and Duration of Study: Data of Daily rainfall and temperature data of 39 years (1980-2019) collected from the meteorological observatory at Regional Agricultural Research Station, Polasa, Jagtial. Methodology: In this study, trend analysis has been carried out on monthly, seasonal and annual basis using the data period between 1980 to 2019 for rainfall and temperature. Mann-Kendall test and Sen’s slope estimate test were applied to identify the existing trend direction and magnitude of change over time. Results: The rainfall seasonal trend analysis indicates that pre-monsoon, monsoon and post-monsoon and winter period showed a negative rainfall trend with z statistics of-1.47, -2.51, -0.55 and-1.38 respectively. However, the annual rainfall showed a negative trend with a z value of -2.53. In the case of Sen’s slope shows that negative trend in monthly, seasonal and annual rainfall. But the significant rising trend of monthly, seasonal average temperature is noticed from 1980 onwards. The annual average maximum temperature in the Jagtial showed an increasing trend (Z value +5.03). An increasing trend in the all seasons will lead to increase in annual mean temperature. The results of minimum temperature shows a rising trend and falling trend observed Monthly. However annual mean minimum temperature in the Jagtial District showed an increasing trend (Z value 0.10). In the case of maximum temperature for the observed period, it showed rising trend (Sen's slope = 0.63) while the minimum temperature trend showed no trend (Sen's slope = 0.02). Conclusion: Time series was carried out using nonparametric M–K test and Sen's slope estimator, which are widely used tests for conducting trend analysis. Therefore, its take into think about the rainfall variability in particular and temperature variability in general of the area into their climate change adaptation approach.
Post‐20 ka Earthquake Scarps Along NE‐Tibet's Qilian Shan Frontal Thrust: Multi‐Millennial Return, ∼Characteristic Co‐Seismic Slip, and Geological Rupture Control

Earthquake slip distributions help constrain rupture behavior and return times. Here, by combining 0.5‐m‐resolution image and topographic data interpretation with fieldwork, we quantify the co‐seismic throw distribution and rupture geometry of the 1609 Hongyazi earthquake along the Qilian Shan Fodongmiao fontal thrust (NE Tibet). We measured 396 vertical offsets across mapped geomorphic units along the thrust trace. The 1609 rupture was ∼118‐km long, with average co‐seismic throw and slip amounts of ∼1.8 ± 1.0 and ∼2.9 ± 1.4 m, respectively, consistent with a magnitude Mw of 7.4 ± 0.3. Along the ∼88‐km‐long western stretch of the thrust, our data also reveal five distinct clusters with peak cumulative throws (∼4.9, 9.3, 13.8, 18.0, and 22.2 m), implying older ruptures with nearly characteristic slip during five Mw ∼ 7.6–7.8 events, three of which were also identified in trenches. Two of these earthquakes ruptured the entire thrust, while three mainly broke the western and middle segments. The thrust geometry and segmentation are influenced by geological inheritance. The middle segment emplaces Silurian granites atop Quaternary alluvium, which may account for its irregularly cusped trace, and favor rupturing during large, Mw ∼7.8 events with multi‐millennium (∼3.7 +0.5/−2.2 ka) return times. Since ∼20 ka, the Fodongmiao Thrust has kept shortening and uplifting Tibet's northeastern boundary at steady rates of ∼1.4 and 1.1 mm/a, respectively. The remaining oblique component of convergence across the ∼800‐km‐long pushup between the Altyn Tagh and Haiyuan faults is absorbed by slip partitioning along the left‐lateral Changma and Lenglongling faults.
Fear of missing out in the digital age: The role of social media satisfaction and advertising engagement

We explore the benefits and costs of social networking usage and examine the roles of need to belong and autonomy to contextualize the fear of missing out (FoMO) socio ‐ cultural phenomenon in the digital age. We utilize a self ‐ determination theory ‐ based framework for understanding how the FoMO phenomenon influences positive (negative) mood, information overload, social media satisfaction, and engagement with social media advertising. Study 1 explores how FoMO relates to positive mood through the need to belong. Study 2 demonstrates how FoMO impacts information overload through the mediation of social media interactivity. Furthermore, Study 2 shows how FoMO alters social media satisfaction, and this relationship is mediated by information overload and moderated by autonomy. Study 3 shows that negative emotions serve to mediate the effect of information overload on engagement with social media advertising. Finally, we discuss implications of this study to provide insight into how brand marketers can offer FoMO ‐ reducing mechanisms to consumers to ensure a high level of advertising engagement, how health advocates can leverage social media to promote meaningful engagement with consumers, and how industry practitioners may want to consider aspirational virtual events to create buzz while also satisfying consumers' need to belong to social groups.

Each agency and Department of Defense component is responsible for funding and managing their respective portions of the effort. The effort is headed by the IHPRPT Steering Committee, which has representatives from each participating agency and service. Industry plays an active role in the program through an involvement in planning, participation at Steering Committee meetings, conducting of technology programs, identification of commercial transition opportunities, advocacy of the program, and teaming.
Application of Laminar Flow Control to the High Speed Civil Transport - the NASA Supersonic Laminar Flow Control Program

The NASA Supersonic Laminar Flow Control (SLFC) program encompasses the development of refined CFD methods and boundary layer stability codes for the highly 3D supersonic flow conditions encountered by the F-16XL technology demonstration aircraft and the prospective High Speed Civil Transport (HSCT). While the F-16XL-1 aircraft continues to gather SLFC data, work is under way on the F-16XL-2 aircraft: which will furnish attach-line design criteria, code-calibration data, and an improved understanding of the flowfield over a wing that will add confidence to the design of HSCTs' boundary layer-controlling air-suction panels.
CDCAT: A multi-language cross-document entity and event coreference annotation tool

: A tool for the manual annotation of cross-document entity and event coreferences that helps annotators to label mention coreference relations in text is essential for the annotation of coreference corpora. To the best of our knowledge, CROss-document Main Events and entities Recognition (CROMER) is the only open-source manual annotation tool available for cross-document entity and event coreferences. However, CROMER lacks multi-language support and extensibility. Moreover, to label cross-document mention coreference relations, CROMER requires the support of another intra-document coreference annotation tool known as Content Annotation Tool, which is now unavailable. To address these problems, we introduce cross-document coreference annotation tool (CDCAT), a new multi-language open-source manual annotation tool for cross-document entity and event coreference, which can handle different input/output formats, preprocessing functions, languages, and annotation systems. Using this new tool, annotators can label a reference relation with only two mouse clicks. Best practice analyses reveal that annotators can reach an annotation speed of 0.025 coreference relations per second on a corpus with a coreference density of 0.076 coreference relations per word. As the ﬁrst multi-language open-source cross-document entity and event coreference annotation tool, CDCAT can theoretically achieve higher annotation efﬁciency than CROMER.
Ultra-wideband power dividers with good isolation and improved sharp roll-off skirt

A novel class of ultra-wideband power dividers with good isolation and sharp roll-off skirt is proposed, analysed and designed on microstrip topology. By introducing a pair of quarter-wavelength short-circuited stubs and/or parallel coupled lines to two symmetrical output ports, good performance in terms of equal power splitting is achieved over the ultra-wideband range, that is 3.1-10.6-GHz. A single resistor is then placed between two output ports such that good isolation is achieved between them. By virtue of direct-current chocked and half-wavelength transmission zeros of short-circuited stubs and coupled lines, out-of-band roll-off skirt near the cut-off frequencies is sharpened to a great extent. Two types of these power dividers are analysed and optimised using the simple transmission-line based even- and odd-mode approach. Based on comparative study of these two types, an ultra-wide band divider with coupled lines has been designed and fabricated. Measured results evidently confirm the predicted features of the divider in terms of return losses at all the three ports, input-to-output insertion losses and output-to-output isolation.
Representation of gyromagnetic composite media for FDTD modeling

A composite media containing particles with a high internal field of magnetic anisotropy (hexagonal ferrites) useful for numerous EMC applications in a wide frequency band is considered. Effective constitutive parameters of a high-loss composite gyromagnetic media are represented in the Lorentzian form. It is convenient for the numerical analysis using the finite-difference time-domain (FDTD) algorithm with a recursive convolution procedure. The equations for the electric and magnetic field updating in such media are represented.
A dynamic clamp protocol to artificially modify cell capacitance

Dynamics of excitable cells and networks depend on the membrane time constant, set by membrane resistance and capacitance. Whereas pharmacological and genetic manipulations of ionic conductances are routine in electrophysiology, experimental control over capacitance remains a challenge. Here, we present capacitance clamp, an approach that allows to mimic a modified capacitance in biological neurons via an unconventional application of the dynamic clamp technique. We first demonstrate the feasibility to quantitatively modulate capacitance in a mathematical neuron model and then confirm the functionality of capacitance clamp in in vitro experiments in granule cells of rodent dentate gyrus with up to threefold virtual capacitance changes. Clamping of capacitance thus constitutes a novel technique to probe and decipher mechanisms of neuronal signaling in ways that were so far inaccessible to experimental electrophysiology.
Efficacy and Safety of Autologous Platelet Concentrate in the Treatment of Photoaging on the Back of the Hands

Introduction: From the fourth decade of life (especially on the back of the hands) the skin becomes dry and brittle, spots appear, the venous network increases and soft tissues decrease. Objective: To evaluate the efficacy and safety of intradermal microinjection of autologous platelet concentrate (APC) in the treatment of rejuvenation of the back of the hands. Method: An observational, analytical and longitudinal study was carried out in 60 patients from the Hospital Clínico Quirúrgico: “Hermanos Ameijeiras”, in the period between March 1, 2017 and March 31, 2020. The treatment was applied monthly for 1 year. The final evaluation was carried out 3 months after the end of the treatment. Results: 51 women with an average age of 45 ± 4.3 years were treated. After treatment, there were significant changes in the Glogau photodamage scale (p = 0.012), in the global scale of aesthetic improvement (p <0.001) and in the scale of the degree of involvement of the volume of the hand (p = 0.018). The adverse events found were pain, inflammation and ecchymosis. The degree of satisfaction reported by the patients was good (26.6%) and very good (73.4%) (p <0.001). Conclusion: The autologous platelet concentrate proved to be effective and safe in reducing the signs of cutaneous aging on the back of the hands, associated with a high degree of patient satisfaction.
Adaptive fuzzy control for uncertain switched discrete-time nonlinear systems in a pure-feedback form with state constraints

This paper is concerned with the adaptive fuzzy control for uncertain switched discrete-time nonlinear systems in a pure-feedback form under arbitrary switchings. The design and the stability analysis of the adaptive fuzzy control with state constraints are based on the adaptive fuzzy backstepping control and the Lyapunov function. The feature of the proposed approach is as follows. (i) The proposed adaptive fuzzy control is designed by suppressing the explosion problem of the complexity in the backstepping control, (ii) In the fuzzy inference approach, the nonlinear uncertainties are approximated by using the fuzzy logic systems based on the simplified extended single-input rule modules, and (iii) The proposed estimator to take the estimates for the unmeasurable states, the adjustable parameters and the real control is in a simplified structure designed. The simulation experiment provides that the proposed approach improves the system performance.
