Asian Herpetological Research 2014年第3期5卷 209-212页

We provide confirmed photographic evidence for the previously overlooked occurrence of the polyphyletic Asian gecko genus Cnemaspis from Gunung Mulu National Park, the world-renowned UNESCO natural heritage site in northern Sarawak, East Malaysia. This new record from Sarawak province represents a remarkable range extension for Cnemaspis cf. kendallii by 550 km to the northeast and denotes the most northern occurrence of the genus in Borneo. Our new finding makes it very likely that these gekkonid lizards also inhabit appropriate limestone karst habitats in adjacent Sabah, Brunei, and Kalimantan. Given the visible differences in the Mulu specimen compared to those from the remaining distribution range on Borneo and the Malaysian Peninsula together with the fact that numerous Cnemaspis species are restricted to small areas, it seems plausible that another undescribed, rather cryptic and possibly locally endemic Bornean species is involved. Lastly, the new record contributes to the importance of the Mulu National Park as a major conservation area in East Malaysia of international concerns.

This contribution presents a novel wear dependent virtual flow rate sensor for single stage single lobe progressing cavity pumps. We study the wear-induced material loss of the pump components and the impact of this material loss on the volumetric efficiency. The results are combined with an established backflow model to implement a backflow calculation procedure that is adaptive to wear. We use a laboratory test setup with a highly abrasive fluid and operate a pump from new to worn condition to validate our approach. The obtained measurement data show that the presented virtual sensor is capable of calculating the flow rate of a pump being subject to wear during its regular operation.

Introduction: A correlation between AVPR1A promoter polymorphisms and prepulse inhibition (PPI) of startle reflexes has been described in healthy adults. Many children with nocturnal enuresis (NE) have a reduced PPI and treatment with desamino arginine vasopressin (dDAVP), a ligand of the arginine vasopressin receptor 1A (AVPR1A), and both improve clanical symptoms and significantly increase PPI. Methods: In 17 children (median 9.1 years, range 6.4-17.3) with NE, promoter repeats within the RS1 and RS3 regions of AVPR1A were quantified and correlated to PPI (native and age-adjusted). Results: No direct correlation was found between the number of promoter repeats at RS1 and PPI (correlation coefficient—0.240, p = 0.346) or RS3 and PPI (correlation coefficient—0.0192, p = 0.936), with no change through age-adjustment of PPI. The different RS3 length subgroups did not show differences in PPI, nor did differentiation of NE according to clinical subtype or treatment response to dDAVP show differences in the number of promoter repeats. Conclusion: The missing reproducibility of the correlation between AVPR1A promoter polymorphisms and PPI in a group with wide range of PPI suggests a more complex interaction. Therefore, further investigations are needed to analyze this very plausible interaction. Conditions with a reduced PPI, such as enuresis, schizophrenia or autism, are particularly interesting for this research.

Controlling the optical response of a medium through suitably tuned coherent electromagnetic fields is highly relevant in a number of potential applications,from all-optical modulators to optical storage *** particular,electromagnetically induced transparency(EIT)is an established phenomenon in which destructive quantum interference creates a transparency window over a narrow spectral range around an absorption line,which,in turn,allows to slow and ultimately stop light due to the anomalous refractive index *** we report on the observation of a new form of both induced transparency and amplification of a weak probe beam in a strongly driven silicon photonic crystal resonator at room *** effect is based on the oscillating temperature field induced in a nonlinear optical cavity,and it reproduces many of the key features of EIT while being independent of either atomic or mechanical *** thermo-optically induced transparency will allow a versatile implementation of EIT-analogs in an integrated photonic platform,at almost arbitrary wavelength of interest,room temperature and in a practical,low cost,and scalable system.

Since late 2022, the share of infections caused by the SARS-CoV2 lineage XBB.1.5 has gradually increased in the United States,resulting in XBB.1.5 becoming the dominating SARS-CoV-2lineage in the United States and a similar trend is likely to soontake place also in European countries. However, information onthe virological properties of XBB.1.5 is scarce. Here, weconducted an initial virological assessment of the SARS-CoV-2XBB.1.5 lineage.

Despite previous circulation of the highly transmissible and antibody evasive BA.2.75, BQ.1, XBB.1 and XBB.1.5 lineages, the share of infections caused by the SARS-CoV-2 lineage XBB.1.16 has gradually increased in India in early 2023, resulting in XBB.1.16 being the dominating SARS-CoV-2 lineage in India today. Since a similar trend may also take place in other countries and information on the biological properties of the XBB.1.16 lineage is scarce, we conducted a rapid assessment of the SARS-CoV-2 XBB.1.16 lineage with respect to its ability to enter cells and evade neutralisation by antibodies.
