6-by-6 Double Word Squares

The November 1975 issue of Word Ways presented a set of 52 7-by-7 word squares that were generated by computer from a list of boldface words from Webster\u27s Collegiate Dictionary (Seventh Edition) plus the appendices of boys\u27 and girls\u27 names. This article reports on the results of a similar computer search for 6-by-6 double word squares

Wallpaper Maps

A wallpaper map is a conformal projection of a spherical earth onto regular polygons with which the plane can be tiled continuously. A complete set of distinct wallpaper maps that satisfy certain natural symmetry conditions is derived and illustrated. Though all of the projections have been published before, the family had not been characterized as a whole. Some wallpaper maps generalize to one-parameter subfamilies in which the sphere is pre-transformed by a conformal automorphism

5-by-5 Palindromic Word Squares

A 5-by-5 palindromic word square is one in which the first word is a reversal of the fifth word, the second is a reversal of the fourth, and the third is a palindrome. The most famous of these squares, the Latin one given at the right, can be translated Arepo the begetter (or sower) holds the wheels with care . It has been found on ancient walls and on amulets for safe childbirth; there is an extensive literature discussing its religious or mystical significance (see, for example, pp. 207-210 of Dmitri Borgmann\u27s Language on Vacation (Scribner\u27s, 1965))

7x7 Computer-Generated Word Squares

A computer search for seven-letter word squares that can be made from words in Webster\u27s Collegiate Dictionary, 7th edition, turned up only 52 examples. Specifically, these were constructed from a corpus of 9663 seven-letter words: single words listed in boldface type in the main body of the dictionary (including proper names), and names from the appendices of boys\u27 and girls\u27 first names. had this corpus been expanded to include inferred words not given in boldface, such as plurals of nouns, -ING and -ED forms of verbs, and -ER and -EST forms of adjectives, many more squares would have been found, including at least four of the eight 7x7 word squares presented by Dmitri Borgmann at the start of Chapter 7 in Language on Vacation (Scribner\u27s, 1965)

Reasoning about the Conant Gasket

Previously conjectured properties of the Conant gasket, a particular non-periodic tiling of the non-negative integer grid, are proved using new recurrences. A slabwise periodicity property is identified and proved. Further fractal properties are conjectured

Radical political unionism reassessed

Defections from European social-democratic parties and a resurgence of union militancy have prompted some to diagnose a new left-wing trade unionism across Europe. This comment on the article by Connolly and Darlington scrutinizes trends in France and Germany but primarily analyses recent developments in Britain. While there are some instances of disaffiliation from the Labour Party, support for electoral alternatives, growth in political militancy and emphasis on new forms of internationalism, these have been limited. There is insufficient evidence to suggest that we are witnessing the making of a new radical collectivism

Even faster sorting of (not only) integers

In this paper we introduce RADULS2, the fastest parallel sorter based on radix algorithm. It is optimized to process huge amounts of data making use of modern multicore CPUs. The main novelties include: extremely optimized algorithm for handling tiny arrays (up to about a hundred of records) that could appear even billions times as subproblems to handle and improved processing of larger subarrays with better use of non-temporal memory stores

Night‑time use of electronic devices, fear of missing out, sleep difficulties, anxiety, and well‑being in UK and Spain: a cross‑cultural comparison

Data availability The data that support the findings of this study are available in the repository: https://osf.io/5scb7/?view_only=de34082b5aaf460fb79a14b701e403e1Electronic devices such as smartphones have become a primary part of young people's lives. Fear of missing out seems to influence the ability to set boundaries around sleep time. This study aims to explore (1) the use of electronic media devices in presleep time, quality of sleep, anxiety, and well-being in females and males’ university students in the UK and Spain, (2) whether university students’ fear of missing out (FoMO) is associated with a higher usage of electronic devices at night-time by gender. A cross-sectional, quantitative design through Qualtrics.com was used. Samples were formed by N = 159 British participants, and N = 172 Spanish. Findings from this study suggest that fear of missing out in females is a predictor, in both countries, of electronic devices usage at night-time but not in males. Night-time usage of electronic devices is a predictor of: higher sleep difficulties in British males and females and in Spanish females, higher FoMO in females from both countries but not in males, and higher negative experiences in Spanish females. Night-time usage of electronic devices did not predict satisfaction with life or loneliness. There is a lack in the literature examining general electronic devices usage habits during night-time, fear of missing out, well-being and mental health, a lack of cross-cultural studies and that consider well-being not with positive or negative factors but from a broad perspective of the construct. Findings suggest the necessity to evaluate students’ levels of FoMO in clinical practice, especially in females, and to incorporate this construct in prevention and intervention programs

Determining the effects of cattle grazing treatments on Yosemite toads (Anaxyrus [=Bufo] canorus) in montane meadows.

Amphibians are experiencing a precipitous global decline, and population stability on public lands with multiple uses is a key concern for managers. In the Sierra Nevada Mountains (California, USA), managers have specifically identified livestock grazing as an activity that may negatively affect Yosemite toads due to the potential overlap of grazing with toad habitat. Grazing exclusion from Yosemite toad breeding and rearing areas and/or entire meadows have been proposed as possible management actions to alleviate the possible impact of cattle on this species. The primary objective of this study was to determine if different fencing treatments affect Yosemite toad populations. We specifically examined the effect of three fencing treatments on Yosemite toad breeding pool occupancy, tadpoles, and young of the year (YOY). Our hypothesis was that over the course of treatment implementation (2006 through 2010), Yosemite toad breeding pool occupancy and early life stage densities would increase within two fencing treatments relative to actively grazed meadows due to beneficial changes to habitat quality in the absence of grazing. Our results did not support our hypothesis, and showed no benefit to Yosemite toad presence or early life stages in fenced or partially fenced meadows compared to standard USDA Forest Service grazing levels. We found substantial Yosemite toad variation by both meadow and year. This variation was influenced by meadow wetness, with water table depth significant in both the tadpole and YOY models
