India is endowed with a proud history of inclusive government and religious tolerance. Indian citizenship has always been firmly rooted in the country’s constitution, which lays priority on equality, regardless of gender, caste, religion, class, community or language. Attaching citizenship rights to religious affiliation runs counter to the letter and spirit of India’s Constitution and constitutional morality. The major thrust of the present article is to project government’s stance on the Citizenship Amendment Act, 2019, constitutional provisions in relation to the Act, thematic arguments of critics and constitutional experts on the matter, multifarious challenges ahead in respect of its implementation, by establishing the fact that any measure taken must remain in conformity with international norms and values and necessity of amending the law to do away with the arbitrary selection of countries and religious groups so that the current agitation can be easily tranquilised.

THE IDENTIFICATION and measurement of adrenocortical steroids in body fluids over the past 2 decades have made possible an extensive exploration of adrenal function. This review is restricted to adrenocortical metabolism in the fetus, infant and child. No attempt will be made to cover all of this rapidly developing area of endeavor. Certain aspects have been treated in other review articles, to which the reader is referred. The reviews by Moore on fetal endorinology, Klein on neonatal adrenal physiology, Lieberman and Teich and Roberts and Szego on steroid biochemistry, White and Wettstein and Anner on adrenal cortical hormones, Ingle on cortisone and Gaunt, Renzi and Chart on aldosterone are especially useful. The books by Wilkins and by Talbot and colleagues contain helpful treatments of this area. Due to the prolific nature of even the review literature, it is necessary to make a rather arbitrary selection of material. NEWER METHODOLOGY Within recent years a number of methods have been developed for the estimation of hormones in urine and plasma. Several techniques for the chromatographic separation of the 17-ketosteroids in urine have been described. Of particular value in the diagnosis of virilizing adrenal tumor has been the development of colorimetric methods for the estimation of dehydroepiandrosterone in urine. Some progress has been made in the estimation of corticosteroids in the urine. Techniques for the measurement of 11-oxygenated neutral 17-ketosteroids, pregnanetriol and pregnanediol in the urine of patients with congenital adrenal hyperplasia have been described. There has been a blossoming of methods for estimating steroids in plasma. Several varieties of techniques are now available for the measurement of corticosteroids and 17-ketosteroids in plasma.

It is known that in the quasi-static treatment of ideally elastoplastic solids, lack of uniqueness may occur unless associated flow rules are used. This has been illustrated by a simple example in reference [3]. The present study shows that the uniqueness difficulties in the foregoing and in similar situations disappear, if inertia forces are included in the analysis. As inertia forces in nature are unavoidable there may therefore be nothing improper in the use of nonassociated flow rules. One is simply not permitted to replace the actual dynamic situation in the limit by a quasi-static one. It is shown, however, that an entirely arbitrary selection of yield condition and flow rules is not permissible, but that the combination must satisfy a requirement which is derived. No general proof of uniqueness of dynamic problems for material prescriptions satisfying this requirement is as yet available. It is the purpose of the paper to induce interested investigators to search for such a general proof.

We study classic fair-division problems in a partial information setting. This paper respectively addresses fair division of rent, cake, and indivisible goods among agents with cardinal preferences. We will show that, for all of these settings and under appropriate valuations, a fair (or an approximately fair) division among n agents can be efficiently computed using only the valuations of n − 1 agents. The nth (secretive) agent can make an arbitrary selection after the division has been proposed and, irrespective of her choice, the computed division will admit an overall fair allocation.For the rent-division setting we prove that well-behaved utilities of n − 1 agents suffice to find a rent division among n rooms such that, for every possible room selection of the secretive agent, there exists an allocation (of the remaining n − 1 rooms among the n − 1 agents) which ensures overall envy freeness (fairness). We complement this existential result by developing a polynomial-time algorithm for the case of quasilinear utilities. In this partial information setting, we also develop efficient algorithms to compute allocations that are envy-free up to one good (EF1) and ε-approximate envy free. These two notions of fairness are applicable in the context of indivisible goods and divisible goods (cake cutting), respectively.One of the main technical contributions of this paper is the development of novel connections between different fairdivision paradigms, e.g., we use our existential results for envy-free rent-division to develop an efficient EF1 algorithm.

An analytical method for synthesizing a four-bar linkage as a function generator is presented. The method, which permits the arbitrary selection of four precision points and finite angular ranges, is based on a graphical solution. This permits a preliminary graphical investigation of the six possible linkages before selecting one for analytical treatment.

We describe the development of a new visualization method, called the expression imbalance map (EIM), for detecting mRNA expression imbalance regions, reflecting genomic losses and gains at a much higher resolution than conventional technologies such as comparative genomic hybridization (CGH). Simple spatial mapping of the microarray expression profiles on chromosomal location provides little information about genomic structure, because mRNA expression levels do not completely reflect genomic copy number and some microarray probes would be of low quality. The EIM, which does not employ arbitrary selection of thresholds in conjunction with hypergeometric distribution-based algorithm, has a high tolerance of these complex factors. The EIM could detect regionally underexpressed or overexpressed genes (called, here, an expression imbalance region) in lung cancer specimens from their gene expression data of oligonucleotide microarray. Many known as well as potential loci with frequent genomic losses or gains were detected as expression imbalance regions by the EIM. Therefore, the EIM should provide the user with further insight into genomic structure through mRNA expression.

The customary presentation of surgical procedures to patients in the United States consists of discussions on alternative treatment methods, risks of the procedure(s) under consideration, and potential benefits for the patient. Because the contents of the normal speech signal have not been defined in a way that permits a surgeon systematically to provide alternative auditory signals to a deaf patient, the burden is placed on the surgeon to make an arbitrary selection of candidates and available devices for cochlear prosthetic implantation. In an attempt to obtain some information regarding the ability of a deaf patient to use electrical signals to detect and understand speech, the Good Samaritan Hospital and Neurological Sciences Institute cochlear implant team has routinely performed tympanotomies using local anesthesia and has positioned temporary electrodes onto the round windows of implant candidates. The purpose of this paper is to review our experience with this procedure and to provide some observations that may be useful in a comprehensive preoperative evaluation for totally deaf patients who are being considered for cochlear implantation.

In the preparation of the following survey two methods were possible. I might select for fuller notice certain of the most important productions and by means of them illustrate the progress in this branch of historical science during the period of the war, or I might endeavor to give as complete an account of the literature as possible, including notices of less significant but nevertheless useful publications. I decided upon the second course, partly because the mass of production seemed to me too large and varied to be satisfactorily exhibited by the more or less arbitrary selection of a few works, partly because it often happens that a seemingly unimportant note may be of worth to some scholar who happens to be pursuing research in that particular field—something which in the many years during which I edited the Theologische Jahresbericht I have often found true in my own experience and that of others. Unfortunately the Jahresbericht, which seemed to us indispensable, as well as the Theologische Rundschau, edited by Bousset, whose untimely death we mourn, have both succumbed to the unfavorable conditions of the times. All the more necessary does it seem to create at least a partial substitute for them, and I embraced the opportunity offered me by the editors of this Review the more gladly because in my own country it will for the present be quite impossible to publish such a survey.
