In this paper, we show that a neurally implemented a cognitive architecture with evolutionary dynamics can solve the four-tree problem. Our model, called Darwinian Neurodynamics, assumes that the unconscious mechanism of problem solving during insight tasks is a Darwinian process. It is based on the evolution of patterns that represent candidate solutions to a problem, and are stored and reproduced by a population of attractor networks. In our first experiment, we used human data as a benchmark and showed that the model behaves comparably to humans: it shows an improvement in performance if it is pretrained and primed appropriately, just like human participants in Kershaw et al...

Many physiologically based pharmacokinetic (PBPK) models for environmental chemicals, drugs, and nanomaterials have been developed to aid risk and safety assessments using acslXTM. However, acslXTM has been rendered sunset since November 2015. Alternative modeling tools and tutorials are needed for future PBPK applications. This forum article aimed to: (1) demonstrate the performance of four PBPK modeling software packages (acslXTM, Berkeley MadonnaTM, MATLAB®, and R language) tested using two existing models (oxytetracycline and gold nanoparticles); (2) provide a tutorial of PBPK model code conversion from acslXTM to Berkeley MadonnaTM, MATLAB®, and R language; (3) discuss the advantages and disadvantages of each software package in the implementation of PBPK models in toxicology, and (4) share our perspective about future direction in this field...

The aim of this study was to evaluate the influence of rider's skill on the plasma cortisol levels of trekking horses on two courses, walking on field and forest courses (about 4.5 to 5.1 km each). Three riders of different skills did horse trekking (HT) in a tandem line under a fixed order: advanced-leading, beginner-second and intermediate-last. A total of six horses were used and they experienced all positions in both courses; a total of 12 experiments were done. Blood samples were obtained before HT, immediately after and 2 h after HT...

Software for computer animation is generally characterized by a steep learning curve, due to the entanglement of both sophisticated techniques and interaction methods required to control 3D geometries. This paper proposes a tool designed to support computer animation production processes by leveraging the affordances offered by articulated tangible user interfaces and motion capture retargeting solutions. To this aim, orientations of an instrumented prop are recorded together with animator's motion in the 3D space and used to quickly pose characters in the virtual environment...

BACKGROUND: In neurosurgery education, there is a paradigm shift from time-based training to criterion-based model for which competency and assessment becomes very critical. Even virtual reality simulators provide alternatives to improve education and assessment in neurosurgery programs and allow for several objective assessment measures, there are not many tools for assessing the overall performance of trainees. This study aims to develop and validate a tool for assessing the overall performance of participants in a simulation-based endoneurosurgery training environment...

Our understanding of biological role of glycans O-sulfation remains at the level of beginners due to microheterogeneity, lability and other difficulties of exact structural assignment. Partially, problem of functional investigations, especially determination of glycoepitope specificity of carbohydrate-binding proteins could be solved with the help of synthetic glycans of certain structure. Here we summing up our synthetic efforts in creation of synthetic O-sulfatome, and bring together all the synthesized in our group sulfated glycans, both existing in nature, yet undiscovered but biochemically licit, and completely unnatural...

In casual conversations, words often lack segments. This study investigates whether listeners rely on their experience with reduced word pronunciation variants during the processing of single segment reduction. We tested three groups of listeners in a lexical decision experiment with French words produced either with or without word-medial schwa (e.g., /ʀəvy/ and /ʀvy/ for revue). Participants also rated the relative frequencies of the two pronunciation variants of the words. If the recognition accuracy and reaction times for a given listener group correlate best with the frequencies of occurrence holding for that given listener group, recognition is influenced by listeners' exposure to these variants...

Für die Therapie des metastasierten kastrationsresistenten Prostatakarzinoms (mCRPC) stehen inzwischen mehrere moderne Wirkstoffe zur Verfügung. Sie verdrängen zunehmend die aufgrund mangelnder Alternativen lange Jahre üblichen sekundären Hormonmanipulationen, denn neuere Substanzen konnten - im Gegensatz zu den konventionellen antihormonellen Therapien - das Überleben in Phase-III-Studien verlängern. So ist der Beginn der mCRPC-Therapie gemäß Leitlinie der European Association of Urology in den letzten Jahren im Krankheitsverlauf nach vorne gerückt...

Background and Study Aims There is a paucity of literature on beginners' training and on its connection with patient safety for transforaminal epidural steroid injections (TFESIs). This study retrospectively assessed the learning curves and associated complications of neurosurgery residents never previously exposed to TFESI and compared them with experienced board-certified faculty neurosurgeons (BCFNs). Material and Methods Procedure time in minutes, dose-area product (DAP) in cGy*cm(2), periprocedural observations, and complications in 354 TFESIs for radicular pain secondary to lumbar disk herniation or lumbar spinal stenosis were extracted from operative notes and the electronic infiltration logbook in the per-injection format...

Here is a life in three countries, with different cultures, different political structures and even different skies. The constant through all these changes is the addiction of the subject of this story to science and laboratory work. Perhaps the tale that unfolds here will show to some beginners in research that persistence, seasoned with a little luck, can bring results and satisfaction in the long run.

Golfers may injure themselves as a result of repetitive asymmetrical loads exerted on the body by poor swing mechanics. If the repetitive sub-maximal loading is not removed, this repetitive loading will exceed the adaptive capacity of bone, eventually resulting in a stress fracture. Stress fracture of the scapula due to golfing is extremely rare. Only two cases of acromion fracture have been reported. A rare case of nontraumatic coracoid fracture in a 50-year-old female beginner golfer is reported here. The mechanism of injury is also discussed...

Background Observation is mentioned in most ethnographic textbooks, but specific details about how it should be conducted and the practicalities to be considered in ethnographic nursing research are not always explicit. This paper explores the experiences of and challenges faced by a novice nurse researcher who used observation to collect data. Aim To provide a novice researcher's perspective of observation in ethnographic nursing research and to highlight the associated challenges. Discussion Challenges that arose in observation began with determining which perspective to take, followed by rehearsing observation, developing and maintaining a constructive relationship with the observation site, being aware of the influence of the observer, managing interactions between the observed and the observer, and responding to ethical issues...

BACKGROUND: Linear endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) represents a pivotal innovation in interventional pulmonology; determining the best approach to guarantee systematic and efficient training is expected to become a main issue in the forthcoming years. Virtual reality simulators have been proposed as potential EBUS-TBNA training instruments, to avoid unskilled beginners practicing directly in real-life settings. A validated and perfected simulation program could be used before allowing beginners to practice on patients...
