Motion imitation and recognition using parametric hidden Markov models

The recognition and synthesis of parametric movements play an important role in human-robot interaction. To understand the whole purpose of an arm movement of a human agent, both its recognition (e.g., pointing or reaching) as well as its parameterization (i.e., where the agent is pointing at) are important. Only together they convey the whole meaning of an action. Similarly, to imitate a movement

A signal-symbol loop mechanism for enhanced edge extraction

The transition to symbolic information from images involves in general the loss or misclassification of information. One way to deal with this missing or wrong information is to get feedback from concrete hypotheses derived at a symbolic level to the sub-symbolic (signal) stage to amplify weak information or correct misclas-sifications. This paper proposes such a feedback mechanism between the sym

Systematic evaluation of levodopa-carbidopa intestinal gel patient-responder characteristics

Levodopa-carbidopa intestinal gel (LCIG, carbidopa-levodopa enteral suspension in the United States) is a treatment option for advanced Parkinson's disease (PD) patients with motor fluctuations. The objective of this investigation was to identify the baseline characteristics predictive of treatment response, measured by improvement in motor symptom severity, in advanced PD patients treated with LC

Tracking in action space

The recognition of human actions such as pointing at objects ("Give me that...") is difficult because they ought to be recognized independent of scene parameters such as viewing direction. Furthermore, the parameters of the action, such as pointing direction, are important pieces of information. One common way to achieve recognition is by using 3D human body tracking followed by action recognition

Atmospheric CO2 sensing using Scheimpflug-lidar based on a 1.57-µm fiber source

A molecular laser-radar system, based on the Scheimpflug principle, has been constructed and demonstrated for remote sensing of atmospheric CO2 concentrations using Differential Absorption Lidar (DIAL) in the (30012←00001) absorption band. The laser source is a Continues Wave (CW) Distributed-FeedBack (DFB) diode laser seeding an Erbium-doped fiber amplifier, emitting narrowband (3 MHz) tunable ra

Measurement of the exclusive 3He(e, e′p) reaction below the quasielastic peak

The high-precision measurements of the 3He(e,e′) reaction are analyzed using the A1 Collaboration spectrometers at the Mainz microtron MAMI. These were performed in antiparallel kinematics at a central momentum transfer of 685 MeV/c and at energy transfers below the quasielastic peak. Distorted momentum distributions and cross sections were also extracted. It is found that full Faddeev-type calcul

Effect of temperature on the formation of highly oxygenated organic molecules (HOMs) from alpha-pinene ozonolysis

Highly oxygenated organic molecules (HOMs) are important contributors to secondary organic aerosol (SOA) and new-particle formation (NPF) in the boreal atmosphere. This newly discovered class of molecules is efficiently formed from atmospheric oxidation of biogenic volatile organic compounds (VOCs), such as monoterpenes, through a process called autoxidation. This process, in which peroxy-radical

Svensk gymnasial yrkesutbildning : - en framgångsfaktor för en effektiv övergång från skola till arbetsliv eller kejsarens nya kläder?

Syftet med forskningsrapporten är att bilda ett sammanhållet kunskapsläge över svensk gymnasial yrkesutbildning (skolförlagda yrkesprogram och lärlingsutbildning) som omfattar både forskning och regionala såväl som lokala satsningar för att stärka yrkesutbildningen. Forskningsrapporten omfattar två delar: (del 1) en kunskapssammanställning över den forskning som har bedrivits om gymnasial yrkesutb

Prevention of colitis-associated cancer by selective targeting of immunoproteasome subunit LMP7

Chronic inflammation is a well-known risk factor in development of intestinal tumorigenesis, although the exact mechanisms underlying development of colitis-associated cancer (CAC) still remain obscure. The activity and function of immunoproteasome has been extensively analyzed in the context of inflammation and infectious diseases. Here, we show that the proteasomal immunosubunit LMP7 plays an es

Bone marrow absorbed doses and correlations with hematological response during 177Lu-DOTATATE treatments are influenced by image-based dosimetry method and presence of skeletal metastases

This study aimed to compare different image-based methods for bone marrow dosimetry and study the dose–response relationship during treatment with 177Lu-DOTATATE in patients with and without skeletal metastases. Methods: This study included 46 patients with advanced neuroendocrine tumors treated with at least 2 fractions of 177Lu-DOTATATE at Sahlgrenska University Hospital. High- and low-uptake co

Exploring the service and knowledge gap between rehabilitation professionals and employers in the return-to-work process of people with mental health problems in Sweden

Background: Research is needed on how to optimize the return-to-work process for persons with mental health problems.Objective: To develop a model that explains how employer and rehabilitation professional mental health literacy may influence strategies used in the return-to-work of persons with mental health problems.Methods: A grounded theory study design was used to collect and analyse intervie

Highly enantioselective epoxidation of olefins by H 2 O 2 catalyzed by a non-heme Fe(ii) catalyst of a chiral tetradentate ligand

The chiral tetradentate N4-donor ligand, 1-methyl-2-({(S)-2-[(S)-1-(1-methylbenzimidazol-2-yl methyl)pyrrolidin-2-yl]pyrrolidin-1-yl}methyl) benzimidazole (S,S- PDBz L), based on a chiral dipyrrolidine backbone, has been synthesized and its corresponding Fe(ii) complex has been prepared and characterized. The X-ray structure of the complex reveals that the Fe(ii) ion is in a distorted octahedral
