Battle for the People: Ideological Conflict between Soviet Partisans, the German Military, and Ukrainian Nationalists in Nazi-Occupied Ukraine
Soviet historiography discusses the People’s War during the Second World War, the idea that all of the Soviet people rallied to the cause and fought off the Nazi invaders, but this is far from the truth. Within the western borderlands of the Soviet Union multiple conflicting groups fought for control of and support from the people. This was especially true in Ukraine where the German Army, Soviet Partisans and Ukrainian nationalists all fought ‘for the people’ and for their own ideologies. This paper is an attempt to discuss the ideological conflict between the Nazis, the Soviets, and the Ukrainian nationalists, and how the failure or success of these policies led to the legitimizing of policies of mass murder of the local Ukrainian, Jewish, and Polish populations, and how the tension from the partisan struggle continues to this day
Physics-based analysis of Affymetrix microarray data
We analyze publicly available data on Affymetrix microarrays spike-in
experiments on the human HGU133 chipset in which sequences are added in
solution at known concentrations. The spike-in set contains sequences of
bacterial, human and artificial origin. Our analysis is based on a recently
introduced molecular-based model [E. Carlon and T. Heim, Physica A 362, 433
(2006)] which takes into account both probe-target hybridization and
target-target partial hybridization in solution. The hybridization free
energies are obtained from the nearest-neighbor model with experimentally
determined parameters. The molecular-based model suggests a rescaling that
should result in a "collapse" of the data at different concentrations into a
single universal curve. We indeed find such a collapse, with the same
parameters as obtained before for the older HGU95 chip set. The quality of the
collapse varies according to the probe set considered. Artificial sequences,
chosen by Affymetrix to be as different as possible from any other human genome
sequence, generally show a much better collapse and thus a better agreement
with the model than all other sequences. This suggests that the observed
deviations from the predicted collapse are related to the choice of probes or
have a biological origin, rather than being a problem with the proposed model.Comment: 11 pages, 10 figure

Dynamics of the Pionium with the Density Matrix Formalism
The evolution of pionium, the hydrogen-like atom, while passing
through matter is solved within the density matrix formalism in the first Born
approximation. We compare the influence on the pionium break-up probability
between the standard probabilistic calculations and the more precise picture of
the density matrix formalism accounting for interference effects. We focus our
general result in the particular conditions of the DIRAC experiment at CERN.Comment: 14 pages, 2 figures, submitted to J. Phys. B: At. Mol. Phy
A reduced model for shock and detonation waves. II. The reactive case
We present a mesoscopic model for reactive shock waves, which extends a
previous model proposed in [G. Stoltz, Europhys. Lett. 76 (2006), 849]. A
complex molecule (or a group of molecules) is replaced by a single
mesoparticle, evolving according to some Dissipative Particle Dynamics.
Chemical reactions can be handled in a mean way by considering an additional
variable per particle describing a rate of reaction. The evolution of this rate
is governed by the kinetics of a reversible exothermic reaction. Numerical
results give profiles in qualitative agreement with all-atom studies
Hepatitis with Fibrin-Ring Granulomas
Abstract : We describe a 66-year-old woman hospitalized with fever, fatigue and hepatopathy. In her medical history arterial hypertension (treated with propranolol and lisinopril), diabetes mellitus type 2 (no treatment before admission) and a gout arthropathy were noted wherefore a therapy with allopurinol 300 mg per day has been started 4 months before. Liver biopsy revealed fibrin-ring granulomas, compatible with allopurinolinduced hepatitis. Because of persistence of high fever after stopping allopurinol, steroids (1 mg/kg) were started. Under this treatment, she developed pancytopenia and fever. The bone marrow aspiration revealed Leishmania infantum. A second liver biopsy showed amastigotes and a disappearance of the granulomas. The history revealed a travel to Malta 2 years earlier. Despite adequate treatment with liposomal amphotericin B the patient deteriorated and finally died in septic shoc
Investigating the timecourse of accessing conversational implicatures during incremental sentence interpretation
Many contextual inferences in utterance interpretation are explained as following from the nature of conversation and the assumption that participants are rational. Recent psycholinguistic research has focussed on certain of these ‘Gricean’ inferences and have revealed that comprehenders can access them in online interpretation. However there have been mixed results as to the time-course of access. Some results show that Gricean inferences can be accessed very rapidly, as rapidly as any other contextually specified information (Sedivy, 2003; Grodner, Klein, Carbery, & Tanenhaus, 2010); while other studies looking at the same kind of inference suggest that access to Gricean inferences are delayed relative to other aspects of semantic interpretation (Huang & Snedeker, 2009; in press). While previous timecourse research has focussed on Gricean inferences that support the online assignment of reference to definite expressions, the study reported here examines the timecourse of access to scalar implicatures, which enrich the meaning of an utterance beyond the semantic interpretation. Even if access to Gricean inference in support of reference assignment may be rapid, it is still unknown whether genuinely enriching scalar implicatures are delayed. Our results indicate that scalar implicatures are accessed as rapidly as other contextual inferences. The implications of our results are discussed in reference to the architecture of language comprehension
The current prevalence of child sexual abuse worldwide: a systematic review and meta-analysis
Objectives: Systematic reviews on prevalence estimates of child sexual abuse (CSA) worldwide included studies with adult participants referring on a period of abuse of about 50years. Therefore we aimed to describe the current prevalence of CSA, taking into account geographical region, type of abuse, level of country development and research methods. Methods: We included studies published between 2002 and 2009 that reported CSA in children below 18years. We performed a random effects meta-analysis and analyzed moderator variables by meta-regression. Results: Fifty-five studies from 24 countries were included. According to four predefined types of sexual abuse, prevalence estimates ranged from 8 to 31% for girls and 3 to 17% for boys. Nine girls and 3 boys out of 100 are victims of forced intercourse. Heterogeneity between primary studies was high in all analyses. Conclusions: Our results based on most recent data confirm results from previous reviews with adults. Surveys in children offer most recent estimates of CSA. Reducing heterogeneity between studies might be possible by standardized measures to make data more meaningful in international comparison
Scaffolding School Pupils’ Scientific Argumentation with Evidence-Based Dialogue Maps
This chapter reports pilot work investigating the potential of Evidence-based Dialogue Mapping to scaffold young teenagers’ scientific argumentation. Our research objective is to better understand pupils’ usage of dialogue maps created in Compendium to write scientific ex-planations. The participants were 20 pupils, 12-13 years old, in a summer science course for “gifted and talented” children in the UK. Through qualitative analysis of three case studies, we investigate the value of dialogue mapping as a mediating tool in the scientific reasoning process during a set of learning activities. These activities were published in an online learning envi-ronment to foster collaborative learning. Pupils mapped their discussions in pairs, shared maps via the online forum and in plenary discussions, and wrote essays based on their dialogue maps. This study draws on these multiple data sources: pupils’ maps in Compendium, writings in science and reflective comments about the uses of mapping for writing. Our analysis highlights the diversity of ways, both successful and unsuccessful, in which dialogue mapping was used by these young teenagers
A tunable macroscopic quantum system based on two fractional vortices
We propose a tunable macroscopic quantum system based on two fractional
vortices. Our analysis shows that two coupled fractional vortices pinned at two
artificially created \kappa\ discontinuities of the Josephson phase in a long
Josephson junction can reach the quantum regime where coherent quantum
oscillations arise. For this purpose we map the dynamics of this system to that
of a single particle in a double-well potential. By tuning the \kappa\
discontinuities with injector currents we are able to control the parameters of
the effective double-well potential as well as to prepare a desired state of
the fractional vortex molecule. The values of the parameters derived from this
model suggest that an experimental realisation of this tunable macroscopic
quantum system is possible with today's technology.Comment: We updated our manuscript due to a change of the focus from qubit to
macroscopic quantum effect
