The phrase "a very weak connection" is correct and usable in written English.
It can be used to describe a relationship or link that lacks strength or significance, whether in a literal or metaphorical sense.
Example: "The evidence presented in the case was based on a very weak connection between the suspect and the crime scene."
Alternatives: "a tenuous link" or "a flimsy connection."
But apart from these predictable results, there is a very weak connection between the number of places offered to refugees and the GDP per capita.
Most of the wind farms are located at the end of grid, which leads to a very weak connection between wind turbines and power grid.
The eerie, batlike aye-aye has a very weak connection, even though it is known for its ability to gnaw through concrete blocks and metal locks with its rodent-like front teeth.
Also from the map, there is a very weak connection between cities on the east of the Pearl River Delta and those on the west, and this is partly due to the slow progress of the Pearl-river-crossing bridges.
Interestingly enough, many adiabatic processes in the thermodynamic sense are quite rapid, so the Ehrenfest use has, at best, a very weak connection to the initial meaning of the term!
"It was a very weak connection," Holes said.
On the other hand, it may also be argued that, if the construction of dams was indeed a reason for very weak connections in the network, very weak connections should also be observed for the period after the 1990s.
In rats that received NR2d alone (0.2 ± 0.1 mV; Fig. 2C) or NT-3 alone (0.4 ± 0.3 mV; Fig. 2D) very weak connections in a small subset of rats were noted.
The clustering coefficient results also seem to suggest the influence of dam construction (and other anthropogenic influences) on the annual streamflow dynamics, especially through identifying a stretch of period (around the 1950s 1990s) with very weak connections when compared to the rest of the period of data.
Based on the identification of a significant stretch of period (around the 1950s 1990s) with very weak connections with the rest of the period studied, the results also suggest the influence of dam construction (and other anthropogenic factors) on the evolution of annual streamflow dynamics.
It may be premature to associate the very weak connections in the annual streamflow network for the period 1950s 1990s with the influence of dam construction during the 1950s 1990s.
