Recognizing Texture and Hardness by Touch

We have experimented with different neural network based architectures for bio-inspired self-organizing texture and hardness perception systems. To this end we have developed a microphone based texture sensor and a hardnesssensor that measures the compression of the material at a constant pressure.We have implemented and successfully tested both monomodal systems for texture and hardness perceptio

Kunskapsunderlag för socialtjänstens delaktighet i kommunala risk- och sårbarhetsanalyser (Sorsa)

I detta kunskapsunderlag presenteras Sorsamodellen. Modellen sätter kommunala risk- och sårbarhetsanalyser i centrum. Sociala risker uppmärksammas särskilt. Sorsamodellen åskådliggörs i form av en processkarta. I den illustreras processer, aktiviteter och rutiner. Den ger också illustrerande exempel hämtade från kommuner.Sorsamodellen tar sin utgångspunkt i att socialtjänstens bedömningar av riske

Temporal trend of autonomic nerve function and HSP27, MIF and PAI-1 in type 1 diabetes

Aim: Diabetes mellitus type 1 (T1D) has numerous complications including autonomic neuropathy, i.e. dysfunction of the autonomous nervous system. This study focuses on Heat Shock Protein 27 (HSP27), Macrophage Migration Inhibitory Factor (MIF), Plasminogen Activator Inhibitor-1 (PAI-1) and HbA1c and their possible roles in effects of diabetes on the autonomic nervous system.Methods: Patients with Aim Diabetes mellitus type 1 (T1D) has numerous complications including autonomic neuropathy, i.e. dysfunction of the autonomous nervous system.

Differential effects of gaseous versus injectable anesthetics on changes in regional cerebral blood flow and metabolism induced by l-DOPA in a rat model of Parkinson's disease

Preclinical imaging of brain activity requires the use of anesthesia. In this study, we have compared the effects of two widely used anesthetics, inhaled isoflurane and ketamine/xylazine cocktail, on cerebral blood flow and metabolism in a rat model of Parkinson's disease and l-DOPA-induced dyskinesia. Specific tracers were used to estimate regional cerebral blood flow (rCBF - [(14)C]-iodoantipyri

Fotsjukdomar

At least 16 000 foot surgical procedures were performed in Sweden in 2004. The average waiting time for elective foot surgery was 6-9 months in 2005. There is a great variation in incidence of performed foot procedures in the counties in Sweden and the waiting time for surgery varies from 1-40 months in different hospitals. International consensus is the base for treatment of most surgical procedu

The challenge of multicenter studies in diabetic patients with foot infections

Background: A complexity of factors determines outcome of foot ulcer infections in diabetic subjects. Variations in patient characteristics, treatment strategies and differences in health care systems may influence outcome. Objective: To evaluate the homogeneity in patients with diabetic foot ulcer infections of sufficient severity to warrant antibiotic treatment in three different European foot c

Costs of deep foot infections in patients with diabetes mellitus

Objective: To calculate costs for the management of deep foot infections and to identify the most important factors related to treatment costs. Design: Costs for in-hospital care, surgery, investigations, antibacterials, visits to the foot-care team, orthopaedic appliances and topical treatment were calculated retrospectively from diagnosis until healing or death. Multiple regression analysis was

The inpatient care of patients with diabetes mellitus and foot ulcers. A validation study of the correspondence between medical records and the Swedish Inpatient Registry with the consequences for cost estimations

Objectives. To compare the correspondence of discharges and diagnoses between medical records and an administrative database in diabetic patients with foot ulcers and to calculate inpatient costs from the different sources. Design. Discharge data from 117 prospectively followed patients were compared with information from the Swedish Inpatient Registry during the same treatment period for each pat

Diabetikers fotproblem : Rätt prevention och behandling kan halvera risken för amputation

Almost half of all lower leg amputations are performed in patients with diabetes. In over 70 per cent of these cases, amputation is precipitated by progression of foot ulceration to deep gangrenous infection. Most foot ulcers are preceded by trauma, usually due to ill-fitting shoes, and are precipitated by sensory motor neuropathy with varying degrees of peripheral vascular disease. The Swedish Me

Investigation of doping in InAs/GaSb hetero-junctions for tunnel-FETs

We report on the influence of doping on the band-edge abruptness of InAs/GaSb p-n and p-i-n tunnel diodes. Understanding and fabrication of a well-defined and sharp band edge is mandatory for tunnel FET operation. InAs/GaSb nanowire junctions were selectively grown by metal organic chemical vapor deposition (MOCVD) on silicon-on-insulator (SOI) substrates using template assisted selective epitaxy

Complementary III-V heterojunction lateral NW Tunnel FET technology on Si

We demonstrate for the first time a technology which allows the monolithic integration of both p-Type (InAs-Si) and n-Type (InAs-GaSb) heterojunction Tunnel FETs (TFET) laterally on a Si substrate. The lateral heterojunction nanowire (NW) structures are implemented using top-down CMOS-compatible processes combined with Template-Assisted Selective Epitaxy (TASE) [1] of the III-V materials. Sub-40nm

III-V heterojunction nanowire tunnel FETs monolithically integrated on silicon

In this presentation we will discuss our recent progress on the integration of InAs/Si p-tunnel FETs (TFETs) and InAs/GaSb n-TFETs on SOI wafers. Local III-V growth is enabled by the development of Template-Assisted Selective Epitaxy (TASE) [1-4]. Both polarity devices have scaled geometries with cross-sections on the order of 30nm. The p-channel InAs/Si TFETs are developed based on our previously

Lateral InAs/Si p-Type Tunnel FETs Integrated on Si - Part 2 : Simulation Study of the Impact of Interface Traps

This part of the paper presents TCAD simulations of the InAs/Si lateral nanowire (NW) tunnel FET (TFET) with the same geometry as the fabricated device discussed in the first part. In addition to band-to-band tunneling, trap-assisted tunneling (TAT) at the InAs/Si and InAs/oxide interfaces was considered. A very good agreement is found between the simulation results and experimental transfer chara

Fabrication and analysis of vertical p-type InAs-Si nanowire tunnel FETs

We report InAs-Si nanowire (NW) Tunnel FETs fabricated inside nanotube templates. High device yield and performances are obtained by optimizing the growth conditions and the fabrication flow using inorganic material as dielectric spacer, atomic-layer-deposition for the metal gate and by scaling the equivalent oxide thickness (EOT). We extract the exponential parameter B of Kane's tunneling model f

Single-Cell Analysis Reveals a Close Relationship between Differentiating Dopamine and Subthalamic Nucleus Neuronal Lineages

Stem cell engineering and grafting of mesencephalic dopamine (mesDA) neurons is a promising strategy for brain repair in Parkinson's disease (PD). Refinement of differentiation protocols to optimize this approach will require deeper understanding of mesDA neuron development. Here, we studied this process using transcriptome-wide single-cell RNA sequencing of mouse neural progenitors expressing the
