Corporate social (ir)responsibility and firm risk: The role of corporate governance
Journal of Financial Research, EarlyView.Abstract We study how corporate governance moderates the relationship between corporate social responsibility (CSR), corporate social irresponsibility (CSI), and firm risk. We find that CSR reduces risk for firms with strong governance. In contrast, CSI increases firm risk more significantly for firms with stronger governance, suggesting that backlash ...

Joint Modulus Zero-Forcing MIMO Detector
, 2019 We propose an improvement over a modulus zero-forcing (MZF) detector proposed earlier in [1] for multi-input multi-output (MIMO) detection, namely, the joint MZF (JMZF) detector.

Secrecy enhancement in wireless networks using precoding-aided rate splitting strategies
Franklin OpenIn the presence of an eavesdropper, the Rate Splitting (RS) technique has been proposed in a Multiple Access Network in this research. By using RS, a message sent from Base Station (BS) is divided into common and private sections.

Low Complexity Wireless Powered Information Transfer Strategy for Multiuser MIMO Systems
IEEE Access, 2018 In this paper, the minimum achievable rate maximization problem for wireless-powered multiple users is investigated. Zero-forcing (ZF)-based precoding is considered for information transmission (IT) in the uplink from multi-antenna users to a multi ...

Why Are All the Sets All the Sets?
Noûs, EarlyView.ABSTRACT Necessitists about set theory think that the pure sets exists, and are the way they are, as a matter of necessity. They cannot explain why the sets (de rebus) are all the sets. This constitutes the Ur‐Objection against necessitism; it is the primary motivation cited by potentialists about set theory.

Zero-Forcing Precoding in the Measured Massive MIMO Downlink: How Many Antennas Are Needed?
International Journal of Antennas and Propagation, 2019 In order to understand how many antennas are needed in a multiuser massive MIMO system, theoretical derivation and channel measurements are conducted; the effect of a finite number of base station (BS) antennas on the performance capability of Zero ...

Orthopaedic Surgery, Volume 17, Issue 5, Page 1389-1396, May 2025.The research utilized a case–control approach to contrast patients experiencing unscheduled readmissions with those undergoing planned readmissions due to staged surgery. Findings indicated a 3.88% rate of unscheduled readmissions, mainly linked to adjacent segment disease, with 3.35% necessitating reoperation.

Optimal Zero-Forcing precoding design : oversampled FB frame approach
, 2010 This paper presents a frame analysis of Zero Forcing (ZF) precoding problem. It shows that from a frame point of view, the filter bank (FB) channel is a synthesis frame and its canonical dual analysis frame is the optimal ZF precoder under total power ...

Pacing and Clinical Electrophysiology, EarlyView.Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to

Joint linear transceiver design over MIMO frequency selective channels
Tongxin xuebao, 2010 The problem of joint linear spatial Tx-Rx design was investigated for multiple-antenna non-block transmission systems over frequency selective channels. A minimum mean square error （MMSE） criterion based linear transceiver was proposed.
