Data from: Orientation-invariance of individual differences in three face processing tasks
2018
Numerous studies have reported impairments in perception and recognition, and, particularly, in part-integration of faces following picture-plane inversion. Whether these findings support the notion that inversion changes face processing qualitatively remains a topic of debate. To examine whether associations and dissociations of the human face processing ability depend on stimulus orientation, we measured face recognition with the Cambridge Face Memory Test (CFMT), along with experimental tests of face perception and selective attention to faces and non-face objects in a sample of 314 participants. Results showed strong inversion effects for all face-related tasks, and modest ones for non-…
The banding pattern of polytene chromosomes of Drosophila guanche compared with that of D. subobscura.
1987
A detailed map of the salivary gland chromosomes of Drosophila guanche is presented and compared to the standard gene arrangements of D. subobscura. Generally, the polytene chromosomc banding patterns of the two species show a high degrce of homology. Only Segment I of the sex chromosome (Chromosome A) shows marked differences. The banding pattern proposed for this segment in D. guanche could have originated from a cluster of overlapping inversions including A1 arrangement.
Factors Affecting Flutter Kicking Speed in Women Who Are Competitive and Recreational Swimmers
2009
The purpose of this study was to determine the relationships between possible predictive measures of a 50 m front crawl swimming and a 22.86 m flutter kicking speed. Ten women who were National Collegiate Athletic Association Division I collegiate swimmers and 10 women who were recreational swimmers (mean +/- SD = 20.6 +/- 1.6 years; 66.7 +/- 10.3 kg; 166.7 +/- 8.8 cm) volunteered for the study. Anthropometric measures were obtained including height, leg length, lower leg length, and foot length. Ankle flexibility was assessed by measuring ankle plantar flexion and ankle inversion. Lower body power was measured using a vertical jump. Swimming and kicking speed were measured as the time to c…
A girl with an atypical form of ataxia telangiectasia and an additional de novo 3.14Mb microduplication in region 19q12
2011
A 9-year-old girl born to healthy parents showed manifestations suggestive of ataxia telangiectasia (AT), such as short stature, sudden short bouts of horizontal and rotary nystagmus, a weak and dysarthric voice, rolling gait, unstable posture, and atactic movements. She did not show several cardinal features typical of AT such as frequent, severe infections of the respiratory tract. In contrast, she showed symptoms not generally related to AT, including microcephaly, profound motor and mental retardation, small hands and feet, severely and progressively reduced muscle tone with slackly protruding abdomen and undue drooling, excess fat on her upper arms, and severe oligoarthritis. A cranial…
Physiological problems of teleost ambisexuality
1988
The normal occurrence of spontaneous sex inversion among teleosts is a recent item within current concepts on vertebrate reproductive physiology. Investigations on the subject are mostly descriptive and deal with morphological and behavioral aspects. The concept of social control of sex inversion has been received with great interest. However, research on physiological processes that take place inside a fish when it changes sex must be rated as fragmentary. Steroid hormones are supposed to play a major role in sex inversion. But a cause and effect relationship has not yet been established. More experimental studies on more types of ambisexual species are badly needed. Future work will show …
Dziecko w roli rodzica – pomylone role rodzinne. O parentyfikacji w doniesieniach światowych i polskich
2018
Cel. Celem artykułu, o charakterze przeglądowym, jest wyjaśnienie zjawiska parentyfikacji, jej uwarunkowań i konsekwencji z nią związanych. Parentyfikacja najczęściej określana jest jako odwrócona rola w rodzinie i dotyczy zamiany roli między rodzicem a dzieckiem. Dochodzi do niej wówczas gdy rodzic, częściowo lub całkowicie rezygnuje ze swoich zadań i obowiązków rodzicielskich. Abdykacja rodzica uruchamia proces parentyfikacji, w którym zwykle jedno, najczęściej najstarsze dziecko w rodzinie, czuje się oddelegowane do przejęcia roli rodzicielskiej, w różnych sferach życia rodzinnego. Świadoma pomoc i obowiązki mogą mieć charakter instrumentalny lub emocjonalny. Dziecko poddane procesowi pa…
Gravity-derived Moho map for Latvia
2020
A precise understanding of crustal structure is essential to the fields of geodynamics, seismology and certain branches of geophysics. A boundary between the crust and the mantle is known as the MohoroviÄiÄ discontinuity, simply referred to as the âMohoâ. Moho geometry and depth have been extensively studied in Europe, but there are still regions with little information about it. One such area is the northern Baltics, Latvia in particular. So far, only one seismic refraction profile, spanning from Sovetsk (Kaliningrad) to Kohtla-Järve (Estonia), has been used to study the deep structure of the Earth in Latvia. We propose gravity inversion (ParkerâOldenburg algorithm) to gain more insight i…
Verb-Second and (micro)-variation in two Rhaeto-Romance varieties of Northern Italy.
2018
Rhaeto-Romance varieties are the only present-day Romance varieties which exhibit the Verb Second constraint (Benincà 1994, Poletto 2002, Salvi 2010). In this chapter we examine two properties typically ascribed to the Verb Second phenomenon, subject-finite verb inversion and restrictions on the co-occurrence of multiple constituents in the sentence-initial position, in two Rhaeto-Romance varieties spoken in South Tyrol (Province of Bolzano, Northern Italy). We demonstrate that both varieties behave like Verb-Second languages as far as both phenomena are concerned, but exhibit a specific Verb-Second system governed by the interplay between syntactic and discourse constraints which differs f…
Comparison of Machine Learning Methods in Stochastic Skin Optical Model Inversion
2020
In this study, we compare six different machine learning methods in the inversion of a stochastic model for light propagation in layered media, and use the inverse models to estimate four parameters of the skin from the simulated data: melanin concentration, hemoglobin volume fraction, and thicknesses of epidermis and dermis. The aim of this study is to determine the best methods for stochastic model inversion in order to improve current methods in skin related cancer diagnostics and in the future develop a non-invasive way to measure the physical parameters of the skin based partially on the results of the study. Of the compared methods, which are convolutional neural network, multi-layer …
Extensional deformations during Neogene chain building in Sicily
2010
ABSTRACT In the Madonie-Nebrodi Mts (Northern Sicily belt) both Mesozoic carbonate platform/basin-derived deformed successions and Neogene foredeep deposits outcrop. Thrust sheets piled-up southwards in thin-skin piggy-back sequence. The chain building process began during the Oligo-Miocene. The syntectonic deposits involved in the compressional tectonics give evidence that syn-sedimentary extensional faults developed during fold nucleation and amplification. Syn-sedimentary extensional faults affect the foredeep strata at different stratigraphic levels, which are bounded by unconformities. Normal faults and bedding show constant cut-off relationships and are progressively tilted youngwards…
