An optimal code for patient identifiers.
2004
How to distinguish 1 billion individuals by an identifier consisting of eight characters, allowing a reasonable amount of error detection or even error correction? Our solution of this problem is an optimal code over a 32-character alphabet that detects up to two errors and corrects one error as well as a transposition of two adjacent characters. The corresponding encoding and error checking algorithms are available for free; they are also embedded as components of the pseudonymisation service that is used in the TMF-the German telematics platform for health research networks.
Socio-economic determinants of inter-regional mobility in patients with cancer
2017
This paper presents an investigation of inter-regional mobility in patients with cancer. Thanks to the availability of geocoded information on patients’ place of residence, the effect of socio-economic status and of other individual characteristics on inter-regional mobility is analysed through multi-level logit models. The extent of patient’s mobility, and its dependence on socio-economic status raises equity issues, as well as regional policy considerations.
Individual and contextual determinants of inter-regional mobility in cancer patients
2019
This paper will present an investigation of inter-regional mobility in patients with a diagnosis of cancer. By virtue of the availability of geocoded information relating to a patient's place of residence, the effect of socio-economic status and other individual characteristics regarding inter-regional mobility will be analysed by means of multilevel logit models. The results demonstrate the influence of age and comorbidity on mobility propensity, in addition to the treatment type, which plays a role in patient mobility. As contextual determinants, patients residing in less deprived areas show greater mobility than those who reside in materially deprived areas. The extent of patient mobilit…
Religious Organizations and Local Self-government Units as Entities Cooperating in The Enforcement of Criminal Judgements
2019
Związki wyznaniowe oraz jednostki samorządu terytorialnego to podmioty współdziałające w wykonywaniu kar, środków karnych, kompensacyjnych, zabezpieczających, zapobiegawczych oraz przepadku. Można je również traktować w kategoriach organów społecznej kontroli nad wykonywaniem tych orzeczeń. Współdziałanie takich podmiotów uzyskało rangę dyrektywy ustawowej i służyć ma readaptacji społecznej skazanych i zapobieganiu przestępczości. W przypadku przedstawicieli związków wyznaniowych współdziałanie posiada także charakter wychowawczy i poprawczy. Religious organizations and local self-government units are entities cooperating in the implementation of penalties, penal, compensatory, protective a…
The effect of neighborhood frequency in reading: Evidence with transposed-letter neighbors
2007
Transposed-letter effects (e.g., jugde activates judge) pose serious models for models of visual-word recognition that use position-specific coding schemes. However, even though the evidence of transposed-letter effects with nonword stimuli is strong, the evidence for word stimuli is scarce and inconclusive. The present experiment examined the effect of neighborhood frequency during normal silent reading using transposed-letter neighbors (e.g., silver, sliver). Two sets of low-frequency words were created (equated in the number of substitution neighbors, word frequency, and number of letters), which were embedded in sentences. In one set, the target word had a higher frequency transposed-le…
Correlation of oscillatory behaviour in Matlab using wavelets
2014
Here we present a novel computational signal processing approach for comparing two signals of equal length and sampling rate, suitable for application across widely varying areas within the geosciences. By performing a continuous wavelet transform (CWT) followed by Spearman?s rank correlation coefficient analysis, a graphical depiction of links between periodicities present in the two signals is generated via two or three dimensional images. In comparison with alternate approaches, e.g., wavelet coherence, this technique is simpler to implement and provides far clearer visual identification of the inter-series relationships. In particular, we report on a Matlab? code which executes this tec…
Decoding Emotional Valence from Electroencephalographic Rhythmic Activity
2017
We attempt to decode emotional valence from electroencephalographic rhythmic activity in a naturalistic setting. We employ a data-driven method developed in a previous study, Spectral Linear Discriminant Analysis, to discover the relationships between the classification task and independent neuronal sources, optimally utilizing multiple frequency bands. A detailed investigation of the classifier provides insight into the neuronal sources related with emotional valence, and the individual differences of the subjects in processing emotions. Our findings show: (1) sources whose locations are similar across subjects are consistently involved in emotional responses, with the involvement of parie…
Transmission of Genetic Properties in Permutation Problems: Study of Lehmer Code and Inversion Table Encoding
2021
Solution encoding describes the way decision variables are represented. In the case of permutation problems, the classical encoding should ensure that there are no duplicates. During crossover operations, repairs may be carried out to correct or avoid repetitions. The use of indirect encoding aims to define bijections between the classical permutation and a different representation of the decision variables. These encodings are not sensitive to duplicates. However, they lead to a loss of genetic properties during crossbreeding. This paper proposes a study of the impact of this loss both in the space of decision variables and in that of fitness values. We consider two indirect encoding: the …
Teaching GP to program like a human software developer
2019
Program synthesis is one of the relevant applications of GP with a strong impact on new fields such as genetic improvement. In order for synthesized code to be used in real-world software, the structure of the programs created by GP must be maintainable. We can teach GP how real-world software is built by learning the relevant properties of mined human-coded software - which can be easily accessed through repository hosting services such as GitHub. So combining program synthesis and repository mining is a logical step. In this paper, we analyze if GP can write programs with properties similar to code produced by human software developers. First, we compare the structure of functions generat…
La riforma ponderale del Piazzi e le misure utilizzate dagli argentieri siciliani.
2009
Il saggio è il primo capitolo di un lavoro più complessivo sull'evoluzione dei sistemi ponderale predecimali nel quale, avvalendosi di fonti documentarie diverse da quelle tradizionalmente usate per ricerche di tal genere, si affrontera' la tematica dell'evoluzione del sistema ponderale come strumento per la formazione dello stato moderno. In questo saggio si delinea il conflitto della Deputazione dei Pesi e Misure con la corporazione degli argentieri in occasione della riforma ponderale del 1809.
