Sexual size dimorphism (SSD) is a common phenomenon and is a central topic in evolutionary biology. Recently, the importance of pursuing an ontogenetic perspective of SSD has been emphasized, to elucidate the proximate physiological mechanisms leading to its evolution. However, such research has seldom focused on the critical periods when males and females diverge. Using mark-recapture data, we...

Electron-beam therapy is used to treat superficial tumors at a standard 100 cm source-to-surface distance (SSD). However, certain clinical situations require the use of an extended SSD. In the present study, Monte Carlo methods were used to investigate clinical electron beams, at standard and non-standard SSDs, from a Siemens Oncor Avant Garde (Siemens Healthcare, Erlangen, Germany) linear acce...

We show that, unlike the results presented previously in the literature, the transition from an outer Shakura-Sunyaev disk (SSD) to an advectiondominated accretion flow (ADAF) is possible for large values of the viscosity parameter α > 0.5. The transition is triggered by thermal instability of a radiation-pressure-supported SSD. The transition radius is close to the central black hole. We confi...

This paper describes the rationale for the new diagnosis of somatic symptom disorder (SSD) within DSM5. SSD represents a consolidation of a number of previously listed diagnoses. It deemphasizes the centrality of medically unexplained symptoms and defines the disorder on the basis of persistent somatic symptoms associated with disproportionate thoughts, feelings, and behaviors related to these ...

Differential Diagnosis of Speech Sound Disorders in Danish-speaking Children Children with speech sound disorders (SSD) are a heterogeneous group in terms of severity, underlying causes, speech characteristics and response to intervention. The correct identification and remediation of SSD is of particular importance since children with persisting SSD are placed at risk socially, academically an...

RATIONALE Ventilator-associated pneumonia (VAP) causes substantial morbidity and mortality. The influence of subglottic secretion drainage (SSD) in preventing VAP remains controversial. OBJECTIVES To determine whether SSD reduces the overall incidence of microbiologically confirmed VAP. METHODS Randomized controlled clinical trial conducted at four French centers. A total of 333 adult patie...

BACKGROUND The aim of this study was to test the operationalization of DSM-5 somatic symptom disorder (SSD) psychological criteria among Chinese general hospital outpatients. METHODS This multicenter, cross-sectional study enrolled 491 patients from 10 general hospital outpatient departments. The structured clinical "interview about cognitive, affective, and behavioral features associated wit...

Silver sulfadiazine has been used as topical medication in the treatment of partial-thickness burns or secondary degree burns for many years. Pain during daily wound cleansing is the main problem. Urgotul SSD, a hydrocolloid dressing with silver sulfadiazine (SSD) has been reported to reduce infection and exhibit antimicrobial activity in burn wounds. The purpose of the present study was to com...
