Simultaneously induced slow and fast gamma waves travel independently in primate primary visual cortex
Authors: Gautham Bhargava , Ray Supratim 
Published: November 2024

AbstractTravelling waves have been reported for multiple neuronal oscillations across the cortex. Within the primary visual cortex (V1), large visual stimuli (gratings) can induce two gamma oscillations – slow (20-35 Hz) and fast (40-60 Hz), potentially due to two different interneuronal classes. However, wave like behaviour of these rhythms and their relationship is unknown. We showed large gratings to monkeys that simultaneously induced slow and fast gamma while recording from V1 using microelectrode arrays. Both slow and fast gamma were organized as travelling waves that were not locked to stimulus onset. Direction of wave propagation was significantly different but showed no correlation, even in concurrent waves. Slow gamma waves lasted for longer durations than fast gamma. Wave direction varied with stimulus orientation and spatial frequency. Thus, slow and fast gamma oscillations in V1 show unique spatial and temporal wave dynamics signifying that these gamma rhythms are generated by distinct neural circuits.

Published: November 2024

We update earlier lattice results for the binding energies of the flavor antitriplet of strong-interaction-stable doubly bottom, JP=1+ tetraquarks, employing an extended sink construction which produces significantly improved ground-state effective-mass plateaus, as well as new, larger-volume ensembles which reduce possible finite-volume effects at lighter pion masses. The updated bindings are 115(17) MeV for the I=0 member of the antitriplet and 47(8) MeV for its I=1/2 partner. We also provide an update of our earlier study of the variable heavy mass dependence of binding in the 1+ channel and new results on this dependence for binding in the 0+ channel, accessible when the two heavy quarks have unequal masses. Implications of these results of potential relevance to experimental searches for signals of the production of doubly bottom tetraquarks and/or a possible bottom-charm partner of the Tcc are also discussed.

Supercritical CO2-driven intersections of multi-well fracturing fracture network and induced microseismic events in naturally fractured reservoir
Authors: Wang Yongliang , Duan Yifeng , Song Yanpei , Du Yumeng 
Published: November 2024

PurposeSupercritical CO2 (SC–CO2) fracturing is a potential technology that creates a complex fracturing fracture network to improve reservoir permeability. SC–CO2-driven intersections of the fracturing fracture network are influenced by some key factors, including the disturbances generated form natural fractures, adjacent multi-wells and adjacent fractures, which increase the challenges in evaluation, control and optimization of the SC–CO2 fracturing fracture networks. If the evaluation of the fracture network is not accurate and effective, the risk of oil and gas development will increase due to the microseismicity induced by multi-well SC–CO2 fracturing, which makes it challenging to control the on-site engineering practices.Design/methodology/approachThe numerical models considering the thermal-hydro-mechanical coupling effect in multi-well SC–CO2 fracturing were established, and the typical cases considering naturally fracture and multi-wells were proposed to investigate the intersections and connections of fracturing fracture network, shear stress shadows and induced microseismic events. The quantitative results from the typical cases, such as fracture length, volume, fluid rate, pore pressure and the maximum and accumulated magnitudes of induced microseismic events, were derived.FindingsIn naturally fractured reservoirs, SC–CO2 fracturing fractures will deflect and propagate along the natural fractures, eventually intersect and connect with fractures from other wells. The quantitative results indicate that SC–CO2 fracturing in naturally fractured reservoirs produces larger fractures than the slick water as fracturing fluid, due to the ability of SC–CO2 to connect macroscopic and microscopic fractures. Compared with slick water fracturing, SC–CO2 fracturing can increase the length of fractures, but it will not increase microseismic events; therefore, SC–CO2 fracturing can improve fracturing efficiency and increase productivity, but it may not simultaneously lead to additional microseismic events.Originality/valueThe results of this study on the multi-well SC–CO2 fracturing may provide references for the fracturing design of deep oil and gas resource extraction, and provide some beneficial supports for the induced microseismic event disasters, promoting the next step of engineering application of multi-well SC–CO2 fracturing.

Authors: Xiong Pingping , Yang Jun , Wei Jinyi , Shu Hui 
Published: November 2024

PurposeIn many instances, the data exhibits periodic and trend characteristics. However, indices like the Digital Economy Development Index (DEDI), which pertains to science, technology, policy and economy, may occasionally display erratic behaviors due to external influences. Thus, to address the unique attributes of the digital economy, this study integrates the principle of information prioritization with nonlinear processing techniques to accurately forecast rapid and anomalous data.Design/methodology/approachThe proposed method utilizes the new information priority GM(1,1) model alongside an optimized BP neural network model achieved through the gradient descent technique (GD-BP). Initially, the provincial Digital Economic Development Index (DEDI) is derived using the entropy weight approach. Subsequently, the original GM(1,1) time response equation undergoes alteration of the initial value, and the time parameter is fine-tuned using Particle Swarm Optimization (PSO). Next, the GD-BP model addresses the residual error. Ultimately, the prediction outcome of the grey combination forecasting model (GCFM) is derived by merging the findings from both the NIPGM(1,1) model and the GD-BP approach.FindingsUsing the DEDI of Jiangsu Province as a case study, researchers demonstrate the effectiveness of the grey combination forecasting model. This model achieves a mean absolute percentage error of 0.33%, outperforming other forecasting methods.Research limitations/implicationsFirst of all, due to the limited data access, it is impossible to obtain a more comprehensive dataset related to the DEDI of Jiangsu Province. Secondly, according to the test results of the GCFM from 2011 to 2020 and the forecasting results from 2021 to 2023, it can be seen that the results of the GCFM are consistent with the actual development situation, but it cannot guarantee the correctness of the long-term forecasting, so the combination forecasting model is only suitable for short-term forecasting.Originality/valueThis article proposes a grey combination prediction model based on the principles of new information priority and nonlinear processing.
The impact of venture capital subscription on price deviation of private placement: evidence from China
Authors: Guan Jingyi , Wen Xueying , Wen Yunhui 
Published: November 2024

Purpose
The purpose of this study is to examine the role of venture capital (VC) in supporting corporate growth and innovation through participation in private placements. While VC provides essential financial support to companies, it remains unclear whether this involvement serves a strategic investment role or a purely financial one. This study seeks to elucidate the role of VC by analyzing changes in the price discount of private placements following VC participation.

Design/methodology/approach
The authors take the private placement events of China A share listed companies from April 2005 to January 2023 as the sample, and examine the influence of VC subscriptions on price discount rate.

Findings
VC subscriptions to private placements increase information asymmetry, consequently raising the discount rate. This relationship is influenced by the transaction characteristics and information environment. Specifically, VC subscriptions further elevate the discount rate when VC are geographically dispersed from the issuers, possess industry expertise in the issuers’ sector, allocate raised funds for asset restructuring or non-digital investments and when the issuers are in their growth stages. Moreover, the positive correlation between VC subscriptions and the discount rate is more pronounced under conditions of lower internal control quality and weaker external media supervision. Higher discount rates in VC-subscribed private placements result in lower R&D investment and investment efficiency by the issuers, leading to larger-scale VC sell-offs and ultimately diminishing the market and financial performance of the issuers.

Practical implications
The issuers should diligently assess the behaviors and motives of VC and selectively choose issuance targets and methods to manage risks associated with price deviations in private placements. Additionally, this study recommends that regulatory authorities develop a more detailed regulatory framework that considers transaction characteristics and the information environment. This strategy should help optimize external regulatory measures like media coverage and protect the interests of small and medium-sized investors.

Originality/value
This study extends research on the “name chasing” motive and certification effect of VC in private placements, enriches the literature on the mechanisms forming discount rates and provides insights for refining regulatory policies on private placements.
Paramedics’ attitudes toward elderly patients’ self-determination in emergency assignments: a US context
Authors: Holmberg Mats , Presta Douglas , Bremer Anders , Devenish Scott , Svensson Anders 
Published: November 2024

PurposeWith aging, the risk of requiring emergency care increases. Elderly patients who need Emergency Medical Services (EMS) are often vulnerable and dependent, especially when their decision-making ability is reduced, which may intensify the risk of important ethical values being violated. Studies about paramedics’ views on elderly people’s self-determination within EMS settings are scarce. The aim of this study was to explore the attitudes and perceptions of paramedics in a US context regarding self-determination in elderly patients who need emergency care provided by EMS.Design/methodology/approachThe study had an exploratory design, and data were collected using a Delphi technique. A panel of experts consisting of US paramedics was recruited to answer a questionnaire sent out in three rounds. The questionnaire comprised 108 items, derived from a Swedish study on the same topic, rated with a five-point Likert scale ranging from agree to disagree with a predetermined consensus level of 70%.FindingsIn total 21 experts agreed to participate, 15 completed all three rounds, leaving a total response rate of 71%. Finally, 87 out of 108 items reached consensus, of which 60 were “agree” and 27 were “disagree.”Originality/valueThe paramedic–patient relationship is a core in assessing and handling ethical challenges within an advanced practice influenced by the paramedics’ educational level and/or the patient’s physical/mental status. Within a “find it fix it” modus operandi, there is a need to increase paramedics’ competence in understanding and handling advanced ethical challenges in relation to ethical values such as autonomy and self-determination in elderly patients.

Published: November 2024

Purpose
The primary aim of this study is to explore challenges and prospects of Islamic banking system in non-Muslim states to foster regulatory frameworks of the system.

Design/methodology/approach
Content analysis as an integral part of qualitative research was used. Secondary data through the exploration of cursory literature was taken into consideration.

Findings
The findings identified three prime challenges, namely, regulatory, operational and institutional, which are impeding the smooth activities and performances of Islamic banks in using innovative Islamic products and services that can favourably compete with products and services of conventional banking system in non-Muslim states. In addition, strengthening the adoption and performance of Islamic banking in non-Muslim states can efficiently and effectively address the identified and multifarious regulatory, operational and institutional challenges to achieve financial inclusion and overall economic growth.

Research limitations/implications
Challenges encountered and prodigies or potentials of operating Islamic banking system by most of non-Muslim countries remains a pivotal aspect that needs research attention in the recent.

Practical implications
Nonetheless, the limitation of this study is that the study relies on the use of secondary data. However, it has provided a substantial direction for future studies in empirically exploring the variables of this study.

Social implications
Indeed, 19th century was a remarkable turning point in the development and expansion of Islamic banking system in the Muslim world. Many predominant Muslim countries such as Malaysia, Indonesia, Saudi Arabia, Bangladesh, Pakistan, among others have been efficiently and effectively operating Islamic banking system within the framework of Islamic legal provisions. Many non-Muslim countries such as Australia, the UK, USA, etc., have also adopted Islamic banking system.

Originality/value
It is noted that policy directions of the study among others should address the regulatory frameworks that is Shari’ah-compliant in the operation of Islamic banking system in non-Muslim states. It is therefore suggested that the policymakers, Islamic financial experts and regulators should use the innovation that could bring competitiveness into the operation of Islamic banking system in non-Muslim states.

Impact of tool nose size on the performance and wear behavior of carbide tool when boring 1Cr17Ni2 martensitic stainless-steel parts
Authors: Ni Xuejie , Li Weijun , Xu Zhong , Liu Fusheng , Wang Qun , Wan Sinian , Li Maojun , He Hong 
Published: November 2024

Purpose
This study aims to examine the cutting performance of a coated carbide tool during the boring of 1Cr17Ni2 martensitic stainless steel, with a focus on how the tool’s structural parameters, particularly the nose radius, affect the wear patterns, wear volume and lifetime of the cutting tool, and related mechanisms.

Design/methodology/approach
A full factorial boring experiment with three factors at two levels was conducted to analyze systematically the impact of cutting parameters on the tool wear behavior. The evolution of tool wear over the machining time was recorded, and the influences of the cutting parameters and nose radius on wear behavior of the tool were examined.

Findings
The results show that higher cutting parameters lead to significant wear or plastic deformation at the tool nose. When the cutting depth is less than the nose radius, the tool wear tends to be minimized. Larger nose radius tools have weaker chip-breaking but greater strength and wear resistance. Higher cutting parameters reduce wear for the tools with larger nose radius, maintaining their integrity. Wear mechanisms are primarily abrasive, adhesive and diffusion wear. Furthermore, the full-factorial analysis of variance revealed that for the tool with rε = 0.4 mm and 0.8 mm, the factors contributing the most to tool wear were cutting speed (38.76%) and cutting depth (86.43%), respectively.

Originality/value
This study is of great significance for selection of cutting tools and cutting parameters for boring 1Cr17Ni2 martensitic stainless-steel parts.

Notably, the impact of AI augmentation varies based on agents’ experience levels, with inexperienced agents benefiting nearly six times more than their experienced counterparts. Mediation analysis shows that AI augmentation improves response timeliness, accuracy and sentiment, thereby boosting sales.Originality/valueThis study highlights the role of AI augmentation in human–AI collaboration, demonstrates the varying impacts of AI augmentation based on agents’ experience levels and offers insights for organizations on how to regulate AI augmentation to enhance agent responses and drive sales.
Drivers of green innovation and green acquisition: empirical evidence from the food and beverage industry
Authors: Wei Yuyan , Pujari Devashish 
Published: November 2024

Purpose
Green innovation and green acquisition are key green marketing strategies. This paper aims to explore and compare the drivers of green acquisition and green innovation strategies firms adopt. Moreover, the moderating role of top management team (TMT) sustainability commitment is investigated.

Design/methodology/approach
The research model used secondary data based on 1,565 firm-year observations in the beverage and food industry in the US. The two-stage control function approach was used for data analysis.

Findings
Media attention motivates firms to pursue both green innovation and green acquisition. The TMT sustainability commitment plays a pivotal moderating role. It strengthens the link between environmental regulation stringency and green innovation but weakens the impact of media attention on green acquisition.

Practical implications
Managers can leverage the study’s findings to guide sustainable marketing decisions in response to environmental regulations and media scrutiny. Policymakers and investors can encourage firms to adopt more sustainable practices, helping align corporate strategies with Sustainable Development Goals 9 and 12.

Originality/value
Though green innovation determinants are extensively studied, most studies rely on surveys or qualitative methods rather than secondary data. Also, as an alternative to developing in-house green technologies or products, the drivers of green acquisition remain unclear despite its growing prevalence. This study addresses both gaps in the sustainable marketing literature.
