Simultaneous information and power transfer over the wireless channels potentially offers great convenience to mobile users. Yet practical receiver designs impose technical constraints on its hardware realization, as circuits for harvesting energy from radio signals are not yet able decode carried directly. To make theoretical progress, we propose a general operation, namely, dynamic splitting (DPS), which splits received signal with adjustable ratio decoding, separately. Three special cases...
This paper deals with an optimal stochastic linear-quadratic (LQ) control problem in infinite time horizon, where the diffusion term dynamics depends on both state and variables. In contrast to deterministic case, we allow weighting matrices cost functional be indefinite. leads indefinite LQ problem, which may still well posed due deep nature of uncertainty involved. The gives rise a algebraic Riccati equation (SARE), is, however, fundamentally different from classical as result problem. To...
In this paper, we study the optimal design for simultaneous wireless information and power transfer (SWIPT) in downlink multiuser orthogonal frequency division multiplexing (OFDM) systems, where users harvest energy decode using same signals received from a fixed access point (AP). For transmission, consider two types of multiple schemes, namely, time (TDMA) (OFDMA). At receiver side, due to practical limitation that circuits harvesting radio are not yet able carried directly, each user...

Purpose As the number of social media users continues to rise globally, a heated debate emerges on whether use improves or harms mental health, as well bidirectional relation between and health. Motivated by this, authors’ study adopts stressor–strain–outcome model compensation hypothesis disentangle effect mechanism psychological well-being. The purpose this paper is address issue. Design/methodology/approach To empirically validate proposed research model, large-scale two-year longitudinal...
Emission trading is widely considered to be the most effective policy minimize overall costs for CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> abatement. However, political feasibility of an emission scheme may crucially depend on free initial allocation permits carbon-intensive industries in order offset reduction profits. This paper aims analyze these potential profit impacts and possible compensation affected generation companies...
This paper investigates an orthogonal frequency division multiplexing (OFDM)-based wireless powered communication system, where one user harvests energy from access point (EAP) to power its information transmission a data (DAP). The channels the EAP user, i.e., transfer (WET) link, and DAP, (WIT) vary over both time slots sub-channels (SCs) in general. To avoid interference at WET WIT are scheduled SCs any slot. Our objective is maximize achievable rate DAP by jointly optimizing SC...
Convex quantile regression (CQR) is a fully nonparametric approach to estimating functions, which has proved useful in many applications of productivity and efficiency analysis. Importantly, CQR satisfies the property, states that observed data split into proportions by frontier for any weight unit interval. expectile (CER) closely related approach, following property: relative share negative deviations equal deviations. The first contribution this paper extend these properties general set...
Modeling user behavior sequences in recommender systems is essential for understanding preferences over time, enabling personalized and accurate recommendations improving retention enhancing business values. Despite its significance, there are two challenges current sequential modeling approaches. From the spatial dimension, it difficult to mutually perceive similar users' interests a generalized intention understanding; from temporal methods generally prone forgetting long-term due...
