Financing constraints, irreversibility and investment dynamics [PDF]

open access: yes
We develop a model of an industry with many heterogeneous firms that face both financing constraints and irreversibility constraints. The financing constraint implies that firms cannot borrow unless the debt is secured by collateral; the irreversibility ...

Irreversibility, uncertainty, and investment [PDF]

open access: yes
Despite its importance to economic growth and the evolution of market structure, the investment behavior of firms, industries, and countries remains poorly understood. This paper has several objectives. First, it reviews some basic models of irreversible

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Irreversibility, Uncertainty, and Investment [PDF]

open access: yes, 1990
Despite its importance to economic growth and the evolution of market structure, the investment behavior of firms, industries, and countries remains poorly understood. This paper has several objectives. First, it reviews some basic models of irreversible investment to illustrate the option-like characteristics of investment opportunities, and to show ...

Adenosine triphosphate as a modulator of protein interactions and stability

open access: yesFEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Investment, irreversibility, and financing constraints in transition economies [PDF]

open access: yes
Using a panel of 4223 Bulgarian, Czech, Polish, and Romanian firms, over the period 1998-2005, we show that financially constrained firms likely to face irreversibility constraints exhibit low and insignificant sensitivities of investment to cash flow ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

open access: yesFEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

The Irreversibility Premium [PDF]

open access: yes
When investment is irreversible, theory suggests that firms will be “reluctant to invest.” This reluctance creates a wedge between the discount rate guiding investment decisions and the standard Jorgensonian user cost (adjusted for risk).

Remarks on the Logic of Irreversible Actions [PDF]

open access: yesKOME: An International Journal of Pure Communication Inquiry, 2014
This paper proposes a logical system in which reversible and irreversible processes could be uniformly handled. This attempt originates in the observation that the question of reversibility not essentially emerges in logic, nor yet in temporal logic in ...

The C‐terminal truncated splicing variant of NK1R negatively modulates substance P‐stimulated NK1R signaling

open access: yesFEBS Open Bio, EarlyView.
The neurokinin 1 receptor exists as full‐length (NK1L) and C‐terminally truncated (NK1S) splice variants. We show that NK1S heterodimerizes with NK1L, impairing Gαq coupling and Ca2+ mobilization while enhancing β‐arrestin1 recruitment. NK1S suppresses substance P‐driven gene expression and cell migration, revealing NK1S as an endogenous biased ...
