TL;DR
There was a divergence between subjects classified as having chemical diabetes as contrasted to overt diabetes, and this apparent separation between subjects with chemical and overt diabetes may explain why patients with chemical diabetes rarely develop overt diabetes.
Abstract
Power amplifiers are a highly important component in a range of industrial applications, such as, servo-drives, magnetic resonance imaging, energy systems, and audio. The control system for power amplifiers should satisfy a range of requirements, e.g., offset free tracking, stability margins, and fast transient response. The intrinsic switching behaviour of modern power amplifiers and the sampled nature of digital control systems represent additional design challenges. This paper presents a complete development cycle for a cascaded digital control system for an industrial current amplifier. The inner control loop contains an optimal state-feedback controller and observer to ensure fast transient response. To guarantee reference-to-output frequency-domain specifications an outer control-loop is designed. Lastly, a rate-limiter is added to prevent clamping in the control input and overstress of the amplifier components. A special attention is given to synchronization in between sub-assemblies of the control system within the FPGA implementation. The paper concludes with the real-time measurements and comparison with the original control systems of the industrial amplifier.

1,302 Citations1971Bernard Desbuquois, G D Aurbach
A method of separation has been developed and applied to radioimmunoassays of insulin, parathyroid hormone, growth hormone and arginine vasopressin, which provides several advantages over the double-antibody precipitation method.

571 Citations1967Herman Friedman, Jerrold Rubin
This paper attacks the problem of exploring the structure of multivariate data in search of “clusters” by using a computer procedure to obtain the “best” partition of n objects into g groups.
Journal of Clinical InvestigationComparison of impedance to insulin-mediated glucose uptake in normal subjects and in subjects with latent diabetes
500 Citations1970Shiao-Wei Shen, Gerald M. Reaven +1 more
A technique was devised for a more accurate measurement than has been heretofore possible of one of the factors responsible for hyperglycemia in the complex syndrome of diabetes, termed impedance, which represents the tissues' insensitivity or resistance to insulin-mediated glucose uptake.
DiabetesA Difference Between the Inheritance of Classical Juvenile-onset and Maturity-onset Type Diabetes of Young People
455 Citations1975Robert Tattersall, Stefan S. Fajans +1 more
A difference in the inheritance of diabetes has been shown between the families of MODY and JOD, providing further evidence of genetic heterogeneity in diabetes mellitus and indicates that there is a need for careful definition of the phenotype of diabetes in populations in which the genetics of diabetes is to be analyzed.
The American Journal of MedicineNonketotic diabetes mellitus: Insulin deficiency or insulin resistance?
359 Citations1976Gerald M. Reaven, Robert M. Bernstein +2 more
It seems apparent from these studies that nonketotic diabetes mellitus can no longer be considered to be a simple function of insulin lack, and that in order to understand this syndrome the authors will need to increase the knowledge of the relationship between insulin deficiency and insulin resistance in patients currently classified as having nonketosis.
Journal of Clinical InvestigationDemonstration of insulin resistance in untreated adult onset diabetic subjects with fasting hyperglycemia.
229 Citations1975Henry N. Ginsberg, George Kimmerling +2 more
It is demonstrated that marked insulin resistance exists in adult onset diabetics with fasting hyperglycemia and the possibility exists that insulin resistance may be characteristic of adult onset diabetes mellitus.

174 Citations1977W J Irvine, R S Gray +2 more
Diabetics treated with oral hypoglycaemic agents within 3 mo of diagnosis had pancreatic-islet-cell antibodies in their sera at diagnosis or later had a high prevalence of a personal history of organ-specific autoimmune disease, thyrogastric antibodies, a family history of insulin-dependent diabetes and possibly of HLA-B8 comparable to that in insulin- dependent diabetes and higher than that expected in a control population or in diabetics controlled by diet alone.
DiabetesStudy of the Relationship Between Glucose and Insulin Responses to an Oral Glucose Load in Man
171 Citations1968Gerald Reaven, Rupert G. Miller
Oral glucose tolerance tests have been performed on 125 patients, and the ensuing changes in plasma glucose and insulin concentrations have been measured, indicating that there was at first an increase, and then, a decrease in the insulin response to progressive degrees of hyperglycemia.

Three criteria for "chemical diabetes" were evaluated by determination of their accuracy in predicting the subsequent development of classic diabetes, as measured by decompensation of carbons, and found to be accurate.

Comparison with other published data indicates that different interpretations of insulin response in subjects with “mild diabetes” have resulted from comparisons of groups with different degrees of glucose intolerance.
DiabetesFurther Evidence that Insulin Resistance Exists in Patients with Chemical Diabetes
90 Citations1974Henry N. Ginsberg, Jerrold M. Olefsky +1 more
Resistance to insulin-mediated glucose uptake is a characteristic of nonobese patients with chemical diabetes, and relatively little overlap existed between steady state plasma glucose levels in normal and diabetic subjects.

The results indicate that insulin resistance can occur as a secondary manifestation of insulin deficiency, and the higher the steady state plasma glucose level, the more the insulin resistance.
DiabetologiaRelationship between heterogeneity of insulin responses and insulin resistance in normal subjects and patients with chemical diabetes
83 Citations1977Gerald M. Reaven, Jerrold M. Olefsky
The results suggest that true heterogeneity exists in patients with abnormal OGTT's, and that the entire population could be divided into two groups characterized by both normal insulin responsiveness and sensitivity, the other by increased insulin response, associated with greater insulin resistance.

81 Citations1970Ross P. Chiles, Manuel Tzagournis +1 more
Decompensated diabetes, manifested by fasting hyperglycemia, was associated with absolute as well as relative deficiency of endogenous insulin, and definite trends in glucose-induced insulin responses could be determined in specific groups, but there was marked individual variation.

The findings show that the rate-limiting step of impaired glucose metabolism (oxidation and lipogenesis) in diabetic fat cells is beyond the interaction of the hormone with the receptor and suggest that the apparent number of hormone receptors (insulin, NSILA) on the cell membrane is regulated individually for each binding site.

Variable involvement of alpha as well as beta cells in the pathophysiology of diabetes is suggested as one explanation for these paradoxic observations.

58 Citations1976Stefan S. Fajans
A tentative classification of diabetes in the young is proposed because of a significant correlation between muscle capillary basement membrane width and known duration of carbohydrate intolerance and a difference in inheritance between the families of juvenile-onset- and maturity-on-type diabetics provides evidence for genetic heterogeneity.
