Physical Realization of the Parity Anomaly in Condensed Matter Physics

Physical Review Letters, 1986
We show that a PbTe-type narrow-gap semiconductor with an antiphase boundary (or domain wall) has currents of abnormal parity and induced fractional charges. A model is introduced which reduces the problem to the physics of a Dirac equation with a soliton in background electric and magnetic fields.

Hyperactivity and Physical Anomalies

Canadian Psychiatric Association Journal, 1976
Hyperactive elementary school boys were matched for age and IQ to a group of normal control children, and the frequency of minor physical anomalies in each group was recorded. Although hyperactives had more of these anomalies than the control children there was not a significant correlation between the degree of hyperactivity and the frequency of ...

Minor Physical Anomalies in Schizophrenia

The Journal of Nervous and Mental Disease, 1994
Using the Waldrop scale, minor physical anomalies were studied in 82 Caucasian subjects, including 41 schizophrenic and 8 bipolar adults, as well as 14 normal and 19 mentally retarded adults. An increased incidence of minor physical anomalies was found in the mentally retarded adults relative to the other groups. Consistent with previous studies, there

Minor Physical Anomalies in Exceptional Children

Journal of Learning Disabilities, 1979
Increasing attention is being paid to biological causes of learning disabilities, and many studies have been mode associating minor physical anomalies (MPAs) with disease, hyperkinesis in boys, and hypokinesis in girls. In an examination of 1,046 children, low-income children had more MPAs than those from middle-income, while middle income children ...

Hyperactive behavior and minor physical anomalies

Acta Psychiatrica Scandinavica, 1985
ABSTRACT– Minor physical anomalies (MPAs) are congenital abnormalities of body structure which reflect fetal maldevelopment. They originate in the same embryonic layer that produces the central nervous system, and it is reasoned that MPAs are markers of nervous system anomalies.

Minor physical anomalies in mentally healthy subjects: Internal consistency of the Waldrop Physical Anomaly Scale

American Journal of Human Biology, 2003
AbstractThe aim of the study was to investigate the prevalence of minor physical anomalies in mentally healthy subjects by using the Waldrop Physical Anomaly Scale and to assess the reliability (internal consistency) of the scale. The subjects were 82 mentally healthy individuals (42 men, 40 women) of Bulgarian origin who were examined for minor ...

Minor physical anomalies in young psychotic children

American Journal of Psychiatry, 1978
The authors examined three groups of children for minor physical anomalies: 52 autistic children, 34 nonautistic siblings of these patients, and 29 normal controls. The total number of anomalies and the weighted score were significantly higher in the autistic children.

Minor Physical Anomalies and Behavior in Preschool Children

Child Development, 1968
In 2 samples of 2,1-year-old children, the presence of multiple minor physical anomalies was found to be positively associated with hyperkinetic, aggressive, impatient, and intractable behavior. Out of approximately 100 reliable behavioral variables, 18 in 1 sample and 16 in the other correlated significantly with weighted scores for minor physical ...
