We present a constructive approach to bounded l2-gain adaptive control with noisy measurements for linear time-invariant scalar systems with uncertain parameters belonging to a finite set. The gain bound refers to the closed-loop system, including the learning procedure. The approach is based on forward dynamic programming to construct a finite-dimensional information state consisting of H-infinit
In 1936, when the Provisional Agreement concerning the Status of Refugees coming from Germany was adopted, the same course was followed: the term refugee covered all persons coming from Germany. The definition of the term refugee was not established by the adoption of the 1967 Refugee Protocol, which created a more or less complete correspondence between the mandate of the UNHCR and treaty law.

We introduce a family of stochastic optimization methods based on the Runge–Kutta–Chebyshev (RKC) schemes. The RKC methods are explicit methods originally designed for solving stiff ordinary differential equations by ensuring that their stability regions are of maximal size. In the optimization context, this allows for larger step sizes (learning rates) and better robustness compared to e.g. the p

We introduce a new model to address three methodological biases in research on new venture growth and survival. The model offers entrepreneurship scholars numerous benefits. The biases are identified using a systematic review of 96 papers using longitudinal data published over a period of 20 years. They are: (1) distributional properties of new ventures; (2) selection bias; and (3) causal asymmetr
Purpose: Finasteride has been shown to reduce the incidence of prostate cancer. Yet the use of finasteride remains low, likely because of the risk of adverse effects. We sought to determine whether prostate-specific antigen (PSA) levels could identify a high-risk subgroup for which the benefits of finasteride treatment outweigh the potential harms. Patients and Methods: Raw data from the Prostate
DevOps as a new way of thinking for software development and operations has received much attention in the industry, while it has not been thoroughly investigated in academia yet. The objective of this study is to characterize DevOps by exploring its central components in terms of principles, practices and their relations to the principles, challenges of DevOps adoption, and benefits reported in t
Starch was isolated from either raw or steam-heated black, red, and lima beans. Isolates from steam-heated legumes were rich in indigestible (resistant) starch (19-31%, dmb), a fact not observed when raw seeds were used. Similarly, resistant starch measured directly in conventionally and high-pressure steamed beans was 3-5 times higher than in the raw pulses, suggesting retrogradation as the major
Today, glucagon-like peptide-1 (GLP-1) receptor agonists are established glucose-lowering drugs used in the management of type 2 diabetes. Their development emerged from the understanding that a combined islet dysfunction comprising of impaired insulin secretion and exaggerated glucagon secretion is the key defect of hyperglycemia. GLP-1 was shown to target these defects, and after the discovery t
Anisotropy of gravitational wave (GW) emission results in a net momentum gained by the black hole (BH) merger product, leading to a recoil velocity up to ∼103 km s−1, which may kick it out of a globular cluster (GC). We estimate GW kick retention fractions of merger products assuming different models for BH spin magnitude and orientation. We check how they depend on BH–BH merger time and propertie
We introduce and present results from the cocoa (Cluster simulatiOn Comparison with ObservAtions) code that has been developed to create idealized mock photometric observations using results from numerical simulations of star cluster evolution. cocoa is able to present the output of realistic numerical simulations of star clusters carried out using Monte Carlo or N-body codes in a way that is usef
Creative workers are increasingly called upon to engage affectually with their work through discourses that demand a love or passion for one’s work. In an organisational setting, these discourses can collapse the distance between selves and work, heightening the sense of personal meaningfulness derived from work. However, these discourses can also be used to discipline an organisationally desirabl
Binding of three mutagens, known to occur in fried or broiled foods, by thirteen different types of dietary fiber was investigated in vitro. Nonspecific binding by other food polymers was minimized by using protease and amylase treatment. Water‐insoluble fiber components were responsible for most of the binding capacity. Generally, a slightly larger proportion of 2‐amino‐3,4‐dimethylimidazo [4,5‐f
The relationship of acute appendicitis occurring previous to cancer in colon and rectum was studied in the consecutive records of 561 patients, of 40 years of age and older, operated upon with an appendectomy because of acute appendicitis. Sixteen (2.9%) of these patients were readmitted within three years because of a carcinoma in colon or rectum. The incidence of carcinoma in the colon and rectu
