TSPYL5 Promotes Triple‐Negative Breast Cancer Metastasis by Antagonizing USP10‐Mediated PTEN Stabilization to Unleash a ZEB1‐Dependent EMT Program

Advanced Science, EarlyView.
The hyperactivation of PI3K/AKT signaling in PTEN wild‐type triple‐negative breast cancer represents a clinical paradox. We delineate a novel post‐translational regulatory axis wherein the oncogene TSPYL5 competitively antagonizes the deubiquitinase USP10.

Non-linear dynamics of size, capital structure and profitability: Empirical evidence from Indian manufacturing sector

, 2017
The identification of optimal level of capital structure has been a topic of research for many years now. Yet, none of the theories on capital structure has been able to provide a convincing answer to this optimum debt problem.

Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

Advanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

A Capital Theory  and  Capital Structure of War

New Perspectives on Political Economy
The article applies an alternative, Austrian economics capital theory to the dynamics of the 'war economy'. It is based on a graphical analysis of a novel capital structure, contrasting with traditional Hayekian representations. We explicitly model the diversion of productive capital into unproductive war goods and describe the particular effect of the

Dual Cytoplasmic and Chloroplastic Mechanisms Fine‐Tune Chloroplast Division through ARC3 Protein Stability

Advanced Science, EarlyView.
ARC3 levels are controlled by cytosolic and chloroplast proteolytic systems. PUB52 mediates ARC3 precursor ubiquitination and degradation in the cytosol, while CLPC1 promotes ARC3 degradation in chloroplasts, where ARC2 protects ARC3 from excessive breakdown. Disrupting these components causes chloroplast division defects, placing them upstream of ARC3.

Capital structure and the firm’s life stage

South African Journal of Business Management, 2005
In this paper we argue the case for a relationship between capital structure and a firm’s life stage. We provide an overview of the two sets of theories and follow this with a proposed linkage between the life stage and capital structure.

The choice of the capital structure of the company according to the framework of theories of capital structure [PDF]

Ekologiya i stroitelstvo, 2015
This article deals with the actual problem of choosing capital structure of a company, because debt ratio has an influence on making strategic decisions of the long-term company’s development, its investment risks, potential interest conflicts between management, owners and lenders.

Friend, Not Foe: Lowered Tissue Reactivity to Long‐Term Polyimide Implants

Advanced Science, EarlyView.
The choice of optimal neural probe designs remains a major challenge in the field of neurotechnology. This study investigated the biocompatibility of several probe variations, including material, thickness, width, and implantation strategy. It highlights the clear advantage of soft polyimide probes over stiff silicon probes for better device ...

Application of Market Timing Theory: Evidence from Canadian Firms [PDF]

International Journal of Management, Accounting and Economics
Internal and external finance are the two primary forms of funding for businesses. Internal financing is derived from retained profits, while external financing may come through borrowing money or the issuance of stocks.

Retina‐Inspired Bi‐Based Terahertz Photonic Neuromorphic Devices

Advanced Science, EarlyView.
Combined with effective band alignment and substrate engineering, bismuth materials are introduced to form terahertz photonic bio‐inspired devices with picosecond short‐term plasticity to enable multi‐scene visual perception. Thus obtained hardware through the terahertz optical neural network (THz‐ONN) demonstrates high recognition accuracy, providing ...
