Personalization framework for adaptive robotic feeding assistance

The final publication is available at link.springer.comThe deployment of robots at home must involve robots with pre-defined skills and the capability of personalizing their behavior by non-expert users. A framework to tackle this personalization is presented and applied to an automatic feeding task. The personalization involves the caregiver providing several examples of feeding using Learning-by- Demostration, and a ProMP formalism to compute an overall trajectory and the variance along the path. Experiments show the validity of the approach in generating different feeding motions to adapt to user’s preferences, automatically extracting the relevant task parameters. The importance of the nature of the demonstrations is also assessed, and two training strategies are compared. © Springer International Publishing AG 2016.Peer ReviewedPostprint (author's final draft

Acral peeling skin syndrome in two East-African siblings: case report

<p>Abstract</p> <p>Background</p> <p>Acral peeling skin syndrome is a rare autosomal recessive genodermatosis due to a missense mutation in transglutaminase 5. The skin peeling occurs at the separation of the stratum corneum from the stratum granulosum.</p> <p>Case presentation</p> <p>We present a case of two siblings who developed continuous peeling of the palms and soles from the first year of life. This peeling was more severe on the soles than palms and on younger sibling than elder sibling. Peeling is worsened by occlusion and sweating.</p> <p>Conclusions</p> <p>Sporadic cases of Acral Peeling Skin Syndrome occur in African population. There is variability in time of presentation and clinical severity even within families.</p

“Vets Restoring Vets”

Introduction Military Veterans disproportionately experience mental health issues due to unique service-related experiences. Peer and social support interventions have shown promise in improving Veterans’ mental health alongside clinical mental health interventions yet there are limited studies on Veteran-designed and Veteran–led peer or social support interventions. This study explored the perceptions and experiences of Veterans participating in an innovative Veteran-designed and Veteran-led peer and social support program. It was a preliminary study in a long-term Community Based Participatory Research partnership between Indiana University School of Medicine-Northwest regional campus and Operation Combat Bikesaver (OCB). Methods   This mixed methods study utilized a limited dataset from pre-and-post-session surveys collected by OCB between September 2019 and August 2021. We examined pre-post differences in participants’ self-rated “feelings” (i.e., emotional state) with the following independent variables through Linear Mixed Models in SPSS: OCB location, OCB event attended, day of the week, time of day, duration of attendance, frequency of attendance, and social assistance. We analyzed participants’ qualitative OCB experiences using inductive thematic analysis in Dedoose.  This study was reviewed and exempted by The Indiana University Human Research Protection Program (Protocol # 12499) on August 16, 2021. Results   A total of 128 participants completed pre-post surveys for 746 OCB sessions. There was a statistically significant pre-post session increase in participants’ feelings (mean=34.6; SD=21.7; p<0.001), with increasing effects by duration (p=0.002) in an OCB session. There was no linear trend in individual pre-and-post session changes in feelings over time. The following themes describe participants’ OCB experiences: sense of purpose and meaning, regaining comradery and brotherhood, “Vets restoring Vets,” satisfaction with OCB structure and processes, and experiencing OCB impacts.  Conclusions   Convening Veterans with shared experiences around innovative and supportive social activities may develop their perceived sense of purpose, belonging, and mutual support and produce improvements in perceived mental health. Future research within this community-regional medical campus research partnership will explore jointly determined research questions to follow-up on the main findings and limitations of the current study

Characterisation of large area THGEMs and experimental measurement of the Townsend coefficients for CF4

Whilst the performance of small THGEMs is well known, here we consider the challenges in scaling these up to large area charge readouts. We first verify the expected gain of larger THGEMs by reporting experimental Townsend coefficients for a 10 cm diameter THGEM in low-pressure CF$_4$. Large area 50 cm by 50 cm THGEMs were sourced from a commercial PCB supplier and geometrical imperfections were observed which we quantified using an optical camera setup. The large area THGEMs were experimentally characterised at Boulby Underground Laboratory through a series of gain calibrations and alpha spectrum measurements. ANSYS, Magboltz and Garfield++ simulations of the design of a TPC based on the large area THGEMs are presented. We also consider their implications for directional dark matter research and potential applications within nuclear security

Skin flora: Differences Between People Affected by Albinism and Those with Normally Pigmented Skin in Northern Tanzania - Cross Sectional Study.

Skin flora varies from one site of the body to another. Individual's health, age and gender determine the type and the density of skin flora. A 1  cm² of the skin on the sternum was rubbed with sterile cotton swab socked in 0.9% normal saline and plated on blood agar. This was cultured at 35 °C. The bacteria were identified by culturing on MacConkey agar, coagulase test, catalase test and gram staining. Swabs were obtained from 66 individuals affected by albinism and 31 individuals with normal skin pigmentation. Those with normal skin were either relatives or staying with the individuals affected by albinism who were recruited for the study. The mean age of the 97 recruited individuals was 30.6 (SD ± 14.9) years. The mean of the colony forming units was 1580.5 per cm2. Those affected by albinism had a significantly higher mean colony forming units (1680  CFU per cm²) as compared with 453.5  CFU per cm² in those with normally pigmented skin (p = 0.023). The skin type and the severity of sun- damaged skin was significantly associated with a higher number of colony forming units (p = 0.038). Individuals affected by albinism have a higher number of colony forming units which is associated with sun- damaged skin

Histological Review of Skin cancers in African Albinos: A 10-year Retrospective Review.

Skin cancer is rare among Africans and albinism is an established risk for skin cancer in this population. Ultraviolet radiation is highest at the equator and African albinos living close to the equator have the highest risk of developing skin cancers. This was a retrospective study that involved histological review of all specimens with skin cancers from African albinos submitted to The Regional Dermatology Training Center in Moshi, Tanzania from 2002 to 2011. A total of 134 biopsies from 86 patients with a male to female ratio of 1:1 were reviewed. Head and neck was the commonest (n = 75, 56.0%) site affected by skin cancers. Squamous cell carcinoma (SCC) was more common than basal cell carcinoma (BCC) with a ratio of 1.2:1. Only one Acral lentiginous melanoma was reported. Majority (55.6%) of SCC were well differentiated while nodular BCC (75%) was the most common type of BCC. Squamous cell carcinoma is more common than basal cell carcinoma in African albinos

Nasopharyngeal oxygen insufflation following pre-oxygenation using the four deep breath technique

Summary This paper evaluates the effectiveness of nasopharyngeal oxygen insufflation following preoxygenation using the four deep breath technique within 30 s, on the onset of haemoglobin desaturation during the subsequent apnoea. Thirty ASA I or II patients were randomly allocated to one of two groups. In the study group (n = 15), pre-oxygenation was followed by insufflation of oxygen at a flow of 5 l.min )1 via a nasopharyngeal catheter commenced at the onset of apnoea. In the control group, pre-oxygenation was not followed by nasopharyngeal oxygen insufflation (n = 15). In the control group, S p O 2 fell to 95% within a mean (SD) apnoea time of 3.65 (1.15) min, whereas in the study group, S p O 2 was maintained in all patients at 100% throughout the 6 min of apnoea, at which point apnoea was terminated and positive pressure ventilation commenced. We conclude that nasopharyngeal oxygen insufflation following pre-oxygenation using the four deep breath technique can delay the onset of haemoglobin desaturation for a significant period of time during the subsequent apnoea. Increasing ambient O 2 fraction from 0.9 to 1.0 more than doubled the time before haemoglobin desaturation fell to 50% and extended the period of apnoea to a greater extent than when the ambient O 2 fraction was increased from 0.21 to 0.9. During brainstem death testing, only one study has compared the effects of 100% oxygen and air as alternative ambient gases on P a O 2 ; patients who had been pre-oxygenated with 100% O 2 developed little or no hypoxaemia when compared to those receiving ai
