One set of 20 subjects learned a list of words early in the morning while another set of 20 learned the same material in the midafternoon. Half of the subjects ( n=10) were tested after an intervening four hours of sleep, while the other 10 were tested after four hours of waking activity. Subjects in the afternoon groups performed better on a recognition task than those in the morning groups, while subjects who had intervening periods of sleep between learning and testing performed better than their counterparts who remained awake. Finally, those subjects who learned in the afternoon and slept prior to testing did best on the recognition task, while those who learned in the morning and remained awake did worst. These results are consistent with the notion that both sleep and circadian rhythms play a role in the memory process.

The effects of cognate synonymy in L2 word learning are explored. Participants learned the names of well-known concrete concepts in a new fictional language following a picture-word association paradigm. Half of the concepts (set A) had two possible translations in the new language (i.e., both words were synonyms): one was a cognate in participants’ L1 and the other one was not. The other half of the concepts (set B) had only one possible translation in the new language, a non-cognate word. After learning the new words, participants’ memory was tested in a picture-word matching task and a translation recognition task. In line with previous findings, our results clearly indicate that cognates are much easier to learn, as we found that the cognate translation was remembered much better than both its non-cognate synonym and the non-cognate from set B. Our results also seem to suggest that non-cognates without cognate synonyms (set B) are better learned than non-cognates with cognate synonyms (set A). This suggests that, at early stages of L2 acquisition, learning a cognate would produce a poorer acquisition of its non-cognate synonym, as compared to a solely learned non-cognate. These results are discussed in the light of different theories and models of bilingual mental lexicon.

AbstractBilinguals may be better than monolinguals at word learning due to their increased experience with language learning. In addition, bilinguals that have languages that are orthotactically different could be more used to dissimilar orthotactic patterns. The current study examines how bilinguals with languages that are orthotactically similar and dissimilar and monolinguals learn novel words that violate or respect the orthotactic legality of the languages they know and how this learning may be affected by the similarity between the bilinguals’ two languages. In Experiment 1, three groups of children were tested: monolinguals, Spanish-Basque bilinguals (dissimilar orthotactic languages), and Spanish-Catalan bilinguals (similar orthotactic languages). After an initial word learning phase, they were tested in a recall task and a recognition task. Results showed that Spanish-Basque bilingual children performed differently than the other two groups. While Spanish monolinguals and Spanish-Catalan bilinguals recognized illegal words worse than legal words, Spanish-Basque bilinguals showed equal performance in learning illegal and legal patterns. A replication study conducted with two new groups of Spanish-Basque children (one group with high Basque proficiency and one group with a lower proficiency) indicated that the effects were not driven by the proficiency in the second language since a similar performance on legal and illegal patterns was observed in both groups. In Experiment 2, two groups of adults, monolinguals and Spanish-Basque bilinguals, were tested with the same task used in Experiment 1. The effect seen in children seems to be absent in adults. Spanish-Basque bilingual adults showed better overall learning performance than monolinguals, irrespective of the illegality of the items. Differences between groups could be due to the effect of having acquired literacy and linguistic competence.

Memory Recognition

32 men and 32 women were given a memory-recognition task involving either quinary or decimal numbers. One half of Ss in each group vocalized the presented items, while the other half read them silently. The design was a 2 × 2 × 2 factorial. Quinary numbers resulted in a greater number of errors of omission and commission than did decimal numbers. Vocalization resulted in greater number of errors of commission in women but the difference did not occur with errors of omission. Recognition was discussed in terms of the amount of transmitted information. The difference in transmitted information between quinary and decimal numbers was analyzed into components accruing from the difference in the number of bits per item and from the difference in the formal interitem similarity.

The aim of this study is to test whether balanced English–Spanish bilingual speakers behave like monolinguals in each of their languages when describing and remembering complex motion events. The semantic domain in question is motion, because some components (namely the manner of motion) are more difficult to lexicalize in Spanish than in English because of typological constraints (see Filipović, 2007; Slobin, 1996, 1997; Talmy, 1985). As a result, performance on a recognition task involving motion verbs could be expected to vary depending on the language used in the experiment. English and Spanish monolinguals and bilinguals performed the recognition task. Results from the monolinguals indicate that there is a language effect based on this typological difference. Specifically, English monolingual speakers performed significantly better than their Spanish peers in the recognition task in both of our conditions, i.e., with verbalization and without verbalization. The bilingual results on the other hand strongly suggest that these speakers tend to adhere to a single lexicalization pattern that is acceptable in both languages, which is the Spanish one in this case. We discuss further implications of these results for language processing and for memory of motion events in general.

Transmission Microscope

We have become accustomed to differentiating between the scanning microscope and the conventional transmission microscope according to the resolving power which the two instruments offer. The conventional microscope is capable of a point resolution of a few angstroms and line resolutions of periodic objects of about 1Å. On the other hand, the scanning microscope, in its normal form, is not ordinarily capable of a point resolution better than 100Å. Upon examining reasons for the 100Å limitation, it becomes clear that this is based more on tradition than reason, and in particular, it is a condition imposed upon the microscope by adherence to thermal sources of electrons.

The sphere of the unknown, supernatural and miraculous is one of the most popular subjects for everyday discussions in Ayodhya – the last of the provinces of the Mughal Empire, which entered the British Raj in 1859, and in the distant past – the space of many legendary and mythological events. Mostly they concern encounters with inhabitants of the “other world” – spirits, ghosts, jinns as well as miraculous healings following magic rituals or meetings with the so-called saints of different religions (Hindu sadhus, Sufi dervishes),with incomprehensible and frightening natural phenomena. According to the author’s observations ideas of the unknown in Avadh are codified and structured in Avadh better than in other parts of India. Local people can clearly define if they witness a bhut or a jinn and whether the disease is caused by some witchcraft or other reasons. Perhaps that is due to the presence in the holy town of a persistent tradition of katha, the public presentation of plots from the Ramayana epic in both the narrative and poetic as well as performative forms. But are the events and phenomena in question a miracle for the Avadhvasis, residents of Ayodhya and its environs, or are they so commonplace that they do not surprise or fascinate? That exactly is the subject of the essay, written on the basis of materials collected by the author in Ayodhya during the period of 2010 – 2019. The author would like to express his appreciation to Mr. Alok Sharma (Faizabad) for his advice and cooperation.

Mature peach trees in pots were treated with nighttime temperatures of –3, 6, 12, and 18 °C for 16 h and a daytime temperature of 20 °C for 8 h until the leaves abscised in the colder treatments. The trees were then chilled at 6 °C for 40 to 70 days. Trees were removed from chilling at 40, 50, 60, and 70 days and placed in a 20 °C greenhouse under increasing daylength, spring conditions. Anthesis was faster and shoot length increased with longer chilling treatments. Trees exposed to –3 °C pretreatment flowered and grew best with 40 days of chilling. However, they did not flower faster or grow better than the other treatments with longer chilling times. There was no difference in flowering or growth between the 6 and 12 °C pretreatments. The 18 °C pretreatment resulted in slower flowering and very little growth after 40 and 50 days of chilling, but growth was comparable to other treatments after 70 days of chilling.

Background: N-Glycosylation is one of the most important post-translational mechanisms in eukaryotes. N-glycosylation predominantly occurs in N-X-[S/T] sequon where X is any amino acid other than proline. However, not all N-X-[S/T] sequons in proteins are glycosylated. Therefore, accurate prediction of N-glycosylation sites is essential to understand Nglycosylation mechanism. Objective: In this article, our motivation is to develop a computational method to predict Nglycosylation sites in eukaryotic protein sequences. Methods: In this article, we report a random forest method, Nglyc, to predict N-glycosylation site from protein sequence, using 315 sequence features. The method was trained using a dataset of 600 N-glycosylation sites and 600 non-glycosylation sites and tested on the dataset containing 295 Nglycosylation sites and 253 non-glycosylation sites. Nglyc prediction was compared with NetNGlyc, EnsembleGly and GPP methods. Further, the performance of Nglyc was evaluated using human and mouse N-glycosylation sites. Results: Nglyc method achieved an overall training accuracy of 0.8033 with all 315 features. Performance comparison with NetNGlyc, EnsembleGly and GPP methods shows that Nglyc performs better than the other methods with high sensitivity and specificity rate. Conclusion: Our method achieved an overall accuracy of 0.8248 with 0.8305 sensitivity and 0.8182 specificity. Comparison study shows that our method performs better than the other methods. Applicability and success of our method was further evaluated using human and mouse N-glycosylation sites. Nglyc method is freely available at https://github.com/bioinformaticsML/ Ngly.
