Thermodynamic hardness and the maximum hardness principle
The Journal of Chemical Physics, 2017An alternative definition of hardness (called the thermodynamic hardness) within the grand canonical ensemble formalism is proposed in terms of the partial derivative of the electronic chemical potential with respect to the thermodynamic chemical potential of the reservoir, keeping the temperature and the external potential constant.

Practice Nursing, 1998
Some evenings ago there was a TV programme on the problems of substance abuse amongst doctors. It highlighted the manner in which their addictions had been hidden from colleagues and the horrendous dangers their patients were exposed to. Nurses also have amongst their number those who use addictive and performance diminishing drugs.

Alkalinity and Hardness: Critical but Elusive Concepts in Aquaculture
, 2016Total alkalinity and total hardness are familiar variables in aquatic animal production. Aquaculturists—both scientists and practitioners alike—have some understanding of the two variables and of methods for adjusting their concentrations.

Currently, graphene is used in aluminum matrix composite manufacturing due to its superior mechanical properties. However, few detailed studies exist on the effect of the process conditions such as sintering temperature (TS), time (tS), and a number of ...

On the Hardness and Approximation of Euclidean DBSCAN
ACM Transactions on Database Systems, 2017DBSCAN is a method proposed in 1996 for clustering multi-dimensional points, and has received extensive applications. Its computational hardness is still unsolved to this date. The original KDD‚96 paper claimed an algorithm of O(n log n) ”average runtime

Hard Instances of Hard Problems
2000This paper investigates the instance complexities of problems that are hard or weakly hard for exponential time under polynomial time, many-one reductions. It is shown that almost every instance of almost every problem in exponential time has essentially maximal instance complexity.

Tight Hardness Results for LCS and Other Sequence Similarity Measures
IEEE Annual Symposium on Foundations of Computer Science, 2015Two important similarity measures between sequences are the longest common subsequence (LCS) and the dynamic time warping distance (DTWD). The computations of these measures for two given sequences are central tasks in a variety of applications.

The Hard Problem is Mainly Hard Work
Cognitive Neuroscience, 2020Doerig et al. point out that there is now a great deal of evidence bearing directly on our understanding of consciousness. However, they argue that the multiplicity of theories suggest that we have a 'lack of stringent criteria specifying how empirical data constrains ToCs.'

JAMA: The Journal of the American Medical Association, 1974
To the Editor.— The medical profession is under attack—hard cases—and unless it cleans its own house, the public will do so for it—bad law. I want to clarify, if possible, the scrambling of the use of the aphorism, in which "hard cases" means hard because of judicial sympathy for one of the parties, and in which "bad law" means a precedent that, if ...
