TL;DR: This classification attempts to establish psychoanalytic criteria for differential diagnoses among different types and degrees of severity of character pathology, to clarify the relationship between a descriptive characterological dihgnosis and a metapsychological, especially structural, analysis, and to arrange subgroups ofcharacter pathology according to their degree of severity.
Abstract: 111s PAPER IS A proposal for a classification of character patholT o n which integrates recent developments in our understanding of severe forms of character pathology, especially tlie so-called “borderline conditions,” with recent developments in psychoanalytic metapsychology. This classification attempts (1) to establish psychoanalytic criteria for differential diagnoses among different types and degrees of severity of character pathology; (2) to clarify the relationship between a descriptive characterological dihgnosis and a metapsychological, especially structural, analysis; and (3) to arrange subgroups of character pathology according to their degree of severity. This system of classification should help in the diagnosis of character pathology by providing the clinician with more systematic information about the descriptive, structural, and genetic-dynamic characteristics of the different forms of character pathology. It should also help in the treatment of patients suffering from character pathology by singling out the predominant constellations of character defenses and other defenses peculiar to the categories of character pathology which I propose to describe. Last, but not least, this proposed classification should help in determining the prognosis for psychological treatment in these conditions by differentiating types of character pathology with varying degrees of indication for psychoanalytic treatment and for psychoanalytically oriented psychotherapy.

TL;DR: In this paper, the authors derived formulas for the Chern-Dold character chU and chU in the theory of universal bordisms and cobordisms U*, respectively.
Abstract: The fundamental results of the paper are: derivation of formulas for the Chern-Dold character chU and chU in the theory of universal bordisms U* and cobordisms U*, respectively; derivation of the formula of a series over the ring Ω*U which gives addition in the formal group of "geometric" cobordisms, and derivation of the formula for the series kΨUk(u), where uU2() and the ΨkU are Adams operators in U*-theory. Bibliography: 13 items.

TL;DR: In this article, it was shown that the nonexistence of nontrivial relations depends on the nonvanishing of Dirichlet's series L(s, χ) at s = 1, when χ is a character with χ(−1) = −1.

TL;DR: A similarity coefficient is defined in which characters are weighted in proportion to the information they convey, and in inverse proportion to their overall association with other characters.
Abstract: A similarity coefficient is defined in which characters are weighted in proportion to the information they convey, and in inverse proportion to their overall association with other characters. The characters may be discrete or continuously variable, or a mixture of both. With discrete characters, and under ideal conditions, it reduces to the ordinary Sokal-Mitchener coefficient. Under nonideal conditions, it offers a significant gain in the objectivity of numerical taxonomic methods by reducing considerably the need for personal skill and judgment in the selection and scoring of characters for use in an analysis of a group of OTU’s.

TL;DR: In this paper, a geometric construction is used to find the matrix representation of the two-particle Green function for a pi-electron model of ethylene, and a self-consistency condition is derived, allowing calculation of highly accurate values for the bond order, ionic character and elementary excitations.


Journal ArticleDOI
TL;DR: The crystal structure of the heterocyclic molecule 1,3-dimethyl-2(3H)-imidazolethione and its 1H n.m.r. spectrum have been interpreted as showing partial double-bond character in the N-C-N system, but no aromaticity as discussed by the authors.

TL;DR: In a character generation system, a bold font is generated by causing the last dot of each horizontal line of dots from which a standard character is formed to be repeated as mentioned in this paper. But this is not the case in our system.
Abstract: In a character generation system a bold font is generated by causing the last dot of each horizontal line of dots from which a standard character is formed to be repeated. A loop-gated shift register converter arrangement determines from an interrogated character store output which dot is the last in each horizontal dot row of the selected character, and then presents the next following register stage.

TL;DR: In this article, a multi-level coded data representing a plurality of laterally spaced vertical scans of a character field passes serially through a multilevel, multi-row shift register synchronously with the scan operation.
Abstract: Multi-level coded data representing a plurality of laterally spaced vertical scans of a character field passes serially through a multi-column, multi-row shift register synchronously with the scan operation. When a character is centered in the register, its height is measured and the register output is fed to an image register at an input position dependent upon character height. Each character representation is thus loaded with precision as to location in the image register. Subsequently, the loaded character is compared with each of a library of characters in a read only memory. More particularly, each element from the read only memory is compared with the element at a corresponding character location in the image register and with each of eight contiguous locations. A count is accumulated and stored indicative of the number of times a mismatch criteria is satisfied from the element comparison. A code is then generated to identify the character from the read only memory for which the count is optimum.

TL;DR: In this article, each character is preassigned closest spacing points at the top, middle, and bottom of the alphanumeric characters, so that one leftmost point of a new character coincides with one right most point of the previous character, thereby insuring close intercharacter spacing.
Abstract: Method and apparatus for producing improved print quality of alphanumeric character combinations. Each character is preassigned closest spacing points at the top, middle, and bottom. Successive characters are positioned so that one left-most point of a new character coincides with one right-most point of the previous character, thereby insuring close intercharacter spacing. Distance measurements from the character body to each spacing point are retained in memory. The left measurements at top, middle and bottom of a new character to be positioned in the print line are subtracted from the right measurements of the top, middle and bottom, respectively, of the previous character in the print line using subtractor circuitry. Maximum value circuits are used to select the largest of the differences thus formed. The print line is displayed on an oscilloscope. The invention may also be practiced using a general purpose digital computer suitably programmed.

TL;DR: In this article, a print control system for line printers of the type including a recirculating line memory adapted to be loaded with digital signals representing the characters to be printed on a line.
Abstract: A print control system for line printers of the type including a recirculating line memory adapted to be loaded with digital signals representing the characters to be printed on a line. Character pulses, one for each character that can be printed, each program a search of the memory for a different associated character, and load a first register with print signals for each column for which that character is to be printed. Odd character pulses direct loading of a second set of registers, one for each column, with the contents of the first register representing the results of the search for each odd character, and even character pulses direct loading of a third set of registers, one for each column, with the contents of the first register representing the results of the search for each even character. The second and third registers are alternately latched for predetermined intervals by overlapping timed firing pulses, and either register, when latched in the print cycle, enables a gate to provide driving current to the hammer driver for that column.
