A Frobenius homomorphism for Lusztig’s quantum groups for arbitrary roots of unity
Authors: Lentner Simon
Published: March 2015

For a finite-dimensional semisimple Lie algebra and a root of unity, Lusztig defined an infinite-dimensional quantum group of divided powers. Under certain restrictions on the order of the root of unity, he constructed a Frobenius homomorphism with finite-dimensional Hopf kernel and with the image of the universal enveloping algebra. In this article, we define and completely describe the Frobenius homomorphism for arbitrary roots of unity by systematically using the theory of Nichols algebras. In several new exceptional cases, the Frobenius–Lusztig kernel is associated to a different Lie algebra than the initial Lie algebra. Moreover, the Frobenius homomorphism often switches short and long roots and/or maps to a braided category.

Distributed Algorithms as Combinatorial Structures
Authors: Censor-Hillel Keren
Published: March 2015

For many distributed computing problems there exists a characterizing combinatorial structure. In other words, the existence of an algorithm for solving the problem on any graph G in time T(G) implies the existence of the structure in G with some parameter related to T(G), and vice versa. Such relations go back to classic examples, such as synchronizers and sparse spanners, and continue to emerge in recent studies of gossip algorithms and multicast algorithms in different communication settings. In this article, we give an overview of both old and recent results that illustrate these connections. We discuss how finding distributed algorithms as well as proving lower bounds can be reduced to studying combinatorial graph structures.

Published: March 2015

CyberGIS is an interdisciplinary field combining advanced cyberinfrastructure, geographic information science and systems (GIS), spatial analysis and modeling, and a number of geospatial domains to improve research productivity and enable scientific breakthroughs. It has emerged as a new-generation GIS that enables synergistic advances in data-driven knowledge discovery, visualization and visual analytics, and collaborative problem solving and decision making. This paper describes a cutting-edge cyberGIS software environment from a system perspective. Two case studies focus on elucidating BioScope: a data-driven and computationally intensive cyberGIS application for bioenergy supply chain optimization, and MovePattern: interactive and multi-scale visual analytics for complex and massive movement data extracted from the Twitter steaming application programming interfaces. These studies demonstrate widely accessible capabilities of cyberGIS for resolving the variety, velocity, and volume of spatial big data to enable unprecedented data-intensive knowledge discovery.
Endoplasmic reticulum and oxidant stress mediate nuclear factor-κB activation in the subfornical organ during angiotensin II hypertension

Published: March 2015

Endoplasmic reticulum (ER) stress and reactive oxygen species (ROS) generation in the brain circumventricular subfornical organ (SFO) mediate the central hypertensive actions of Angiotensin II (ANG II). However, the downstream signaling events remain unclear. Here we tested the hypothesis that angiotensin type 1a receptors (AT1aR), ER stress, and ROS induce activation of the transcription factor nuclear factor-κB (NF-κB) during ANG II-dependent hypertension. To spatiotemporally track NF-κB activity in the SFO throughout the development of ANG II-dependent hypertension, we used SFO-targeted adenoviral delivery and longitudinal bioluminescence imaging in mice. During low-dose infusion of ANG II, bioluminescence imaging revealed a prehypertensive surge in NF-κB activity in the SFO at a time point prior to a significant rise in arterial blood pressure. SFO-targeted ablation of AT1aR, inhibition of ER stress, or adenoviral scavenging of ROS in the SFO prevented the ANG II-induced increase in SFO NF-κB. These findings highlight the utility of bioluminescence imaging to longitudinally track transcription factor activation during the development of ANG II-dependent hypertension and reveal an AT1aR-, ER stress-, and ROS-dependent prehypertensive surge in NF-κB activity in the SFO. Furthermore, the increase in NF-κB activity before a rise in arterial blood pressure suggests a causal role for SFO NF-κB in the development of ANG II-dependent hypertension.
Interlimb communication following unexpected changes in treadmill velocity during human walking

Published: March 2015

Interlimb reflexes play an important role in human walking, particularly when dynamic stability is threatened by external perturbations or changes in the walking surface. Interlimb reflexes have recently been demonstrated in the contralateral biceps femoris (cBF) following knee joint rotations applied to the ipsilateral leg (iKnee) during the late stance phase of human gait (Stevenson AJ, Geertsen SS, Andersen JB, Sinkjær T, Nielsen JB, Mrachacz-Kersting N. J Physiol 591: 4921–4935, 2013). This interlimb reflex likely acts to slow the forward progression of the body to maintain dynamic stability following the perturbations. We examined this hypothesis by unexpectedly increasing or decreasing the velocity of the treadmill before (−100 and −50 ms), at the same time, or following (+50 ms) the onset of iKnee perturbations in 12 healthy volunteers. We quantified the cBF reflex amplitude when the iKnee perturbation was delivered alone, the treadmill velocity change was delivered alone, or when the two perturbations were combined. When the treadmill velocity was suddenly increased (or decreased) 100 or 50 ms before the iKnee perturbations, the combined cBF reflex was significantly larger (or smaller) than the algebraic sum of the two perturbations delivered separately. Furthermore, unexpected changes in treadmill velocity increased the incidence of reflexes in other contralateral leg muscles when the iKnee perturbations were elicited alone. These results suggest a context dependency for interlimb reflexes. They also show that the cBF reflex changed in a predictable manner to slow the forward progression of the body and maintaining dynamic stability during walking, thus signifying a functional role for interlimb reflexes.

Authors: Inal Hasan Ali , Ozturk Inal Zeynep , Alkan Ender
Published: March 2015

Background. Intrauterine contraceptive devices (IUDs) are widely utilized all over the world owing to their low cost and high efficacy. Uterine perforation is a rare complication that may occur at IUD insertion resulting in extrauterine location of the IUD. Traditionally, surgical removal of dislocated IUDs has been recommended.Case. A 68-year-old patient who had an IUD (Lippes loop) inserted 32 years ago and whose routine examination incidentally revealed a dislocated IUD in the abdominal cavity. The patient remained asymptomatic during three years of follow-up and the IUD was left in place.Conclusion. Asymptomatic patients, whose vaginal examinations and ultrasonography or X-ray results reveal a dislocated IUD, may benefit from conservative management.

Published: March 2015

A backpressure filling system is a kind of air type filling system which could be applied to power type, fine or coarse grain, or mixtures with fine and coarse components. The working principle of backpressure filling system was discussed based on fundamental hydromechanics. The research limit values of backpressure were achieved via mechanical analysis. Comparing with the exit velocity of material by theoretical analysis and numerical simulation, the CFD simulation model was confirmed and its related parameters were determined. The CFD numerical simulation shows the relationship between production capacity of packaging machine and backpressure, and the results matched actual operation of the equipment well. Combining with the demand of device capacity, the range of backpressure could be controlled at 8 kPa~11 kPa.
Free Flap Transfer to Preserve Main Arterial Flow in Early Reconstruction of Open Fracture in the Lower Extremity
Authors: Nemoto Mitsuru , Ishikawa Shinsuke , Kounoike Natsuko , Sugimoto Takayuki , Takeda Akira
Published: March 2015

The selection of recipient vessels is crucial when reconstructing traumatized lower extremities using a free flap. When the dorsalis pedis artery and/or posterior tibial artery cannot be palpated, we utilize computed tomography angiography to verify the site of vascular injury prior to performing free flap transfer. For vascular anastomosis, we fundamentally perform end-to-side anastomosis or flow-through anastomosis to preserve the main arterial flow. In addition, in open fracture of the lower extremity, we utilize the anterolateral thigh flap for moderate soft tissue defects and the latissimus dorsi musculocutaneous flap for extensive soft tissue defects. The free flaps used in these two techniques are long and include a large-caliber pedicle, and reconstruction can be performed with either the anterior or posterior tibial artery. The preparation of recipient vessels is easier during the acute phase early after injury, when there is no influence of scarring. A free flap allows flow-through anastomosis and is thus optimal for open fracture of the lower extremity that requires simultaneous reconstruction of main vessel injury and soft tissue defect from the middle to distal thirds of the lower extremity.

Published: March 2015

In medicine knowledge of pH values can provide us with information not only about the patients’ status but also about physiological processes in the patient’s body. Measurements of pH in small-sample volumes and online pH monitoring in vivo can be employed to obtain such information. For such measurements we have developed and investigated U-shaped fiber-optic probes with immobilized pH indicators in this paper. U-shaped probes with a diameter of about 2 mm were prepared. Three different pH indicators, methyl red, methyl orange, and bromothymol blue, were immobilized in two types of matrices, namely, porous silica (PS) and ethylcellulose (EC), and applied on the U-shaped probes. Changes in spectra of transmitted power were measured and calibration curves were determined from these spectra. It has been found that a working pH range of prepared probes was from 3.1 to 7.6. The maximum sensitivity was about 0.1 1/pH unit. Effects of structural relaxations of detection layers and indicator leaching observed in experiments are discussed.
Vibration Properties of a Steel-PMMA Composite Beam
Authors: He Yuyang , Jin Xiaoxiong
Published: March 2015

A steel-polymethyl methacrylate (steel-PMMA) beam was fabricated to investigate the vibration properties of a one-dimensional phononic crystal structure. The experimental system included an excitation system, a signal acquisition system, and a data analysis and processing system. When an excitation signal was exerted on one end of the beam, the signals of six response points were collected with acceleration sensors. Subsequent signal analysis showed that the beam was attenuated in certain frequency ranges. The lumped mass method was then used to calculate the bandgap of the phononic crystal beam to analyze the vibration properties of a beam made of two different materials. The finite element method was also employed to simulate the vibration of the phononic crystal beam, and the simulation results were consistent with theoretical calculations. The existence of the bandgap was confirmed experimentally and theoretically, which allows for the potential applications of phononic crystals, including wave guiding and filtering, in integrated structures.

Objective. Evaluating the efficacy and safety of arginine and glutamine supplementation in decreasing the incidence of NEC among preterm neonates.Methods.Prospective case-control study done on 75 preterm neonates ≤34 weeks, divided equally into L-arginine group receiving enteral L-arginine, glutamine group receiving enteral glutamine, and control group. Serum L-arginine and glutamine levels were measured at time of enrollment (sample 1), after 14 days of enrollment (sample 2), and at time of diagnosis of NEC (sample 3).Results. The incidence of NEC was 9.3%. There was no difference in the frequency of NEC between L-arginine and control groups (P>0.05). NEC was not detected in glutamine group; L-arginine concentrations were significantly lower in arginine group than control group in both samples while glutamine concentrations were comparable in glutamine and control groups in both samples. No significant difference was found between groups as regards number of septic episodes, duration to reach full oral intake, or duration of hospital stay.Conclusion.Enteral L-arginine supplementation did not seem to reduce the incidence of NEC. Enteral glutamine may have a preventive role against NEC if supplied early to preterm neonates. However, larger studies are needed to confirm these findings. This work is registered in ClinicalTrials.gov (ClinicalTrials.gov Identifier:NCT01263041).

Published: March 2015

Goiter is more common in women, suggesting that estrogen could be involved in its physiopathology. The presence of classical estrogen receptors (ERαand ERβ) has been described in thyroid tissue, suggesting a direct effect of estrogen on the gland. A nonclassic estrogen receptor, the G-protein-coupled estrogen receptor (GPER1), has been described recently in several tissues. However, in goiter, the presence of this receptor has not been studied yet. We investigated GPER1 gene and protein expressions in normal thyroid and goiter using reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western blot, respectively. In normal thyroid (n=16) and goiter (n=19), GPER1 gene was expressed in all samples, while GPER1 protein was expressed in all samples of normal thyroid (n=15) but in only 72% of goiter samples (n=13). When comparing GPER1 gene and protein levels in both conditions, gene expression and protein levels were higher in normal thyroid than in goiter, suggesting a role of this receptor in this condition. Further studies are needed to elucidate the role of GPER1 in normal thyroid and goiter.

Abnormal synaptic maturation and connectivity are possible etiologies of autism. Previous studies showed significantly less alpha activity in autism than normal children. Therefore, we studied the effects of anodal tDCS on peak alpha frequency (PAF) related to autism treatment evaluation checklist (ATEC). Twenty male children with autism were randomly assigned in a crossover design to receive a single session of both active and sham tDCS stimulation (11 mA) over F3 (left dorsolateral prefrontal cortex). Pre- to postsession changes in a measure of cortical activity impacted by tDCS (PAF) and ATEC were compared between groups. We also examined the associations between pre- and postsession changes in the PAF and ATEC. The results show significant pre- to postsession improvements in two domains of ATEC (social and health/behavior domains) following active tDCS, relative to sham treatment. PAF also significantly increased at the stimulation site, and an increase in PAF was significantly associated with improvements in the two domains of ATEC impacted by tDCS. The findings suggest that a single session of anodal tDCS over the F3 may have clinical benefits in children with autism and that those benefits may be related to an increase in PAF.

Remodeling of Glucose Metabolism Precedes Pressure Overload-Induced Left Ventricular Hypertrophy: Review of a Hypothesis
Authors: Kundu Bijoy K. , Zhong Min , Sen Shiraj , Davogustto Giovanni , Keller Susanna R. , Taegtmeyer Heinrich
Published: March 2015

When subjected to pressure overload, the ventricular myocardium shifts from fatty acids to glucose as its main source for energy provision and frequently increases its mass. Here, we review the evidence in support of the concept that metabolic remodeling, measured as an increased myocardial glucose uptake using dynamic positron emission tomography (PET) with the glucose analogue 2-deoxy-2-[18F]fluoro-D-glucose (FDG), precedes the onset of left ventricular hypertrophy (LVH) and heart failure. Consistent with this, early intervention with propranolol, which attenuates glucose uptake, prevents the maladaptive metabolic response and preserves cardiac function in vivo. We also review ex vivo studies suggesting a link between dysregulated myocardial glucose metabolism, intracellular accumulation of glucose 6-phosphate (G6P) and contractile dysfunction of the heart. G6P levels correlate with activation of mTOR (mechanistic target of rapamycin) and endoplasmic reticulum stress. This sequence of events could be prevented by pretreatment with rapamycin (mTOR inhibition) or metformin (enzyme 5′-AMP-activated protein kinase activation). In conclusion, we propose that metabolic imaging with FDG PET may provide a novel approach to guide the treatment of patients with hypertension-induced LVH.

Published: March 2015

Objectives: A randomized controlled trial was conducted to evaluate the efficacy of impedance control of a radiofrequency interstitial thermal ablation system (RITA) used to treat hepatocellular carcinoma (HCC). Methods: Fifteen patients with hypervascular HCCs <20 mm in diameter were randomly treated with radiofrequency ablation (RFA) using conventional temperature control (group A) or impedance control methods (group B). RITA needle electrodes were used in all cases. We compared ablation time, extent of lesion ablation, and energy use between the two groups. Results: The median long and short diameters of the axial cross sections of radiofrequency-induced necrotic areas visualized by CT were 32 mm (range, 26-36) and 25 mm (20-31) in group A and 32 mm (28-40) and 31 mm (24-37) in group B, respectively. The short diameter of group B patients was significantly greater than that of group A patients (p = 0.029). The median ablation time was 18.8 min in group A and 13.4 min in group B, thus significantly shorter in group B (p = 0.001). The energy requirement did not differ significantly between the groups. Conclusions: Impedance control of the RITA system resulted in an increased size of the ablation zone and a decreased ablation time.

Purpose: To describe diurnal variation in choroidal thickness (CT) and retinal thickness (RT) of the nine Early Treatment of Diabetic Retinopathy Study (ETDRS) macular subfields determined using swept-source optical coherence tomography. Methods: A prospective study was conducted on 24 healthy Korean volunteers who underwent two sequential measurements of a randomly selected eye at 9 a.m., 1 p.m., and 6 p.m. The radial scan mode was used. To determine the repeatability and reliability, we applied intragrader agreement using the intraclass correlation coefficient (ICC). Results: Significant diurnal variation in CT was observed. The highest mean CT was found at 9 a.m. The lowest mean CT occurred at 1 p.m. There was excellent intragrader agreement, with the ICC ranging from 0.961 to 0.997. There was no significant diurnal variation in RT. Conclusion: There was significant diurnal variation in CT. The choroid was thinner at 1 p.m. than at 9 a.m. and 6 p.m.
Zur Rolle der Exposition bei der Therapie von Angststörungen
Authors: Mohr Cornelia , Schneider Silvia
Published: March 2015

Angststörungen gehören sowohl im Kindes- und Jugendalter als auch im Erwachsenenalter zu den häufigsten psychischen Störungen. Als wirksamste Behandlungsform mit dem höchsten Evidenzgrad hat sich bei Angststörungen in allen Altersgruppen die Kognitive Verhaltenstherapie (KVT) erwiesen. Dabei scheint die Wirksamkeit der KVT im Wesentlichen auf das Therapieelement der Exposition zurückzuführen zu sein und die Exposition wiederum auf dem Lernprinzip der Extinktion (Inhibitionslernen) zu beruhen. Unter Berücksichtigung translationaler Studien arbeitet der vorliegende Artikel den aktuellen Forschungsstand zur Rolle der Exposition bei der Therapie von Angststörungen bei Kindern und Jugendlichen sowie Erwachsenen auf und gibt einen Überblick über empirisch fundierte Strategien zur Steigerung des Expositionserfolgs durch die gezielte Förderung des Extinktionslernens. Hierbei werden Methoden wie die massierte oder variierte Exposition berücksichtigt sowie Mechanismen wie die Kontextkonditionierung, die zu einem erhöhten Rückfallrisiko nach erfolgreicher Therapie führen kann. Ein weiterer Schwerpunkt liegt auf kognitiven Expositionsverstärkern wie D-Cycloserin oder Cortisol, die bei gezielter Einnahme vor oder nach der Exposition die neurologischen Prozesse des Extinktionslernens und der Gedächtniskonsolidierung unterstützen.

Authors: Matzdorff Axel , Schilling Holger , Ledig Bettina
Published: March 2015

Background: Venous thromboembolism (VTE) is a serious threat for all cancer patients. This study was aimed to assess the VTE treatment of cancer patients in the ambulatory care setting. Patients and Methods: This is a prospective non-interventional study, which includes ambulatory cancer patients from office-based oncologists. A standardized case report form was used to obtain data on patient characteristics, treatment regimens, duration of treatment, and side effects. Results: Specialists from 34 centers included data from 76 patients. The median patient age was 62 years (range 33-81 years). The 4 most common cancer types were breast cancer (32%), colorectal cancer (18%), lymphoma and lung cancer (each 8%). 18% of the acute VTE cases were treated as inpatients, 80% as outpatients, and 99% with low-molecular-weight heparin (LMWH), unfractionated heparin (UFH), or fondaparinux. After the acute phase, secondary prophylaxis with LMWH/UFH/fondaparinux was planned in 61% of the patients, with oral anticoagulation in 39%. During acute-phase treatment and secondary prophylaxis, no patient had recurrent VTE. 4 patients (5%) experienced minor bleedings. Conclusions: This study shows that many ambulatory cancer patients with VTE have early tumors, no metastases, and an excellent performance score. Most patients receive LMWHs for secondary prophylaxis, as recommended by the national and international guidelines. Still, a relevant percentage is switched to oral anticoagulants.

Background—

Although the benefits of automatic external defibrillators are undeniable, their effectiveness could be dramatically improved. One of the key issues is the disparity between the locations of automatic external defibrillators and sudden cardiac arrests (SCAs).

Methods and Results—

From emergency medical services and other Parisian agencies, data on all SCAs occurring in public places in Paris, France, were prospectively collected between 2000 and 2010 and recorded using 2020 grid areas. For each area, population density, population movements, and landmarks were analyzed. Of the 4176 SCAs, 1255 (30%) occurred in public areas, with a highly clustered distribution of SCAs, especially in areas containing major train stations (12% of SCAs in 0.75% of the Paris area). The association with population density was poor, with a nonsignificant increase in SCAs with population density (
P
=0.4). Occurrence of public SCAs was, in contrast, highly associated with population movements (
P
<0.001). In multivariate analysis including other landmarks in each grid cell in the model and demographic characteristics, population movement remained significantly associated with the occurrence of SCA (odds ratio, 1.48; 95% confidence interval, 1.34–1.63;
P
<0.0001), as well as grid cells containing train stations (odds ratio, 3.80; 95% confidence interval, 2.66–5.36;
P
<0.0001).

Conclusions—

Using a systematic analysis of determinants of SCA in public places, we demonstrated the extent to which population movements influence SCA distribution. Our findings also suggested that beyond this key risk factor, some areas are dramatically associated with a higher risk of SCA.
Counter-Music: Harun Farocki's Theory of a New Image Type
Authors: Blumenthal-Barby Martin
Published: March 2015

Harun Farocki's 2004 installation Counter-Music explores the issue of surveillance. It probes different kinds of surveillance and, in so doing, delineates historical trajectories, juxtaposing, for instance, state surveillance under Louis XIV in late-seventeenth-century France (through public streetlights) with more recent modes of observation via surveillance cameras (through closed-circuit-television systems). The tacit epicenter of Farocki's installation is the novel form of surveillance in which cameras are linked with automatic-recognition systems that no longer rely on human beings as observers: Human beings have been replaced by software designed to surveil. This new kind of surveillance, in which images are recorded and then “viewed” by automatic “eyes”—that is, analyzed by algorithmic software—generates what Farocki calls “operational images” to be used within systemic surveillance operations.

The drawing, Five Studies of a Woman's Head, now in the British Museum, was produced in a single sitting with the model assuming different poses while the artist drew her. He, too, must have changed his position in order to cast a precipitously downward glance at his model's head, as the two radically foreshortened views of it at the top of the page, and three similar, if less abbreviated, ones on another sheet executed during the same posing session, suggest.
Perceptual Conflicts in a Multi-Stereoscopic Immersive Virtual Environment: Case Study on Face-to-Face Interaction through an Avatar
Authors: Chen Weiya , Clavel Céline , Férey Nicolas , Bourdot Patrick
Published: March 2015

With multi-stereoscopy technology, novel projection-based immersive systems now can support multiple users by providing each one with an independent stereoscopic view of the virtual scene. When users work face-to-face, they may have an incorrect view if objects are located between them. In this case, avatars can be introduced to enable face-to-face interaction in the virtual world, whereas they are side-by-side in the real device. As a consequence, such multi-user systems provide the users with a new kind of perceptual immersion and related cognitive experiences, because users must handle both information from the real world (i.e., other users' bodies) and those from the virtual scene (i.e., other users' avatars) at the same time. In this study, we experimentally created special interaction situations to examine the perceptual conflicts generated by the dual-presence of the real and virtual visual and audio stimuli. In a two-user scenario, participants performed an object-picking task according to three types of instructions (verbal, gestural, or multimodal instructions) given by an experimenter. This co-located experimenter was also virtually present by an avatar in the virtual world to enable face-to-face interactions with the participants. Our goal was to observe to what extent the perceptual conflicts induced by the dual-presence of the experimenter can be integrated without significantly altering the performance of the participants. For that, we studied the influence of such perceptual conflicts on participants' choice of collaborator (whether they interacted with the avatar or the real experimenter) and on their task efficiency. As the results showed, first users had an a priori choice of collaborator (avatar or real person) and this choice did not change under different experimental conditions. Second, perceptual conflicts had an impact on users' performance in terms of task completion time. We discuss the implications of these results for designing a better immersive system for co-located collaboration between multiple users.

[currently Mitromorpha algeriana (Pallary, 1900) comb. nov.] considered as a synonym of Mitromorpha columbellaria (Scacchi, 1836). The latter is the oldest available name for the most common and widespread Mediterranean species of Mitromorpha. A lectotype is selected for Mitra leontocroma Brusina, 1866 [currently Mitromorpha leontocroma (Brusina, 1866) comb. nov.], previously considered as a junior synonym of Mitromorpha olivoidea (Cantraine, 1835) but here considered as a junior synonym of Mitromorpha columbellaria (Scacchi, 1836). Mitromorpha melitensis (Mifsud, 1993) is a synonym of Mitromorpha olivoidea (Cantraine, 1835). Mitromorpha mediterranea Mifsud, 2001 is a synonym of Mitromorpha columbellaria (Scacchi, 1836).
Addendum to: Joseph Vachal (1838–1911): French entomologist and politician (Zootaxa, 3442, 1–52)
Authors: RASMUSSEN CLAUS , ASCHER JOHN S.
Published: March 2015

A series of recent papers has compiled brief biographies and listed the scientific publications and taxa proposed for a number of bee researchers (Rasmussen et al. 2007; Zuparko 2007; Rasmussen & Ascher 2008; Rasmussen et al. 2009; Rasmussen 2012; Rasmussen et al. 2013). Unfortunately five taxa attributed in the original publication to Vachal were overlooked in the recent review of his taxonomic work (Rasmussen 2012). Whereas these five names for halictine bees appeared with brief Latin descriptions in the publication by Kohl (1905), all other hymenopteran taxa described by Kohl in this paper had descriptions in German. At least one of the halictine names has been attributed to Kohl (Warncke, 1984), but based on the fact that 1) Kohl gave Vachal the authorship (as “J. Vachal n. sp.”) and 2) the five descriptions are in a different language from the taxa described by Kohl in the same paper, these five names should all be referred to Vachal as pointed out by Ebmer (1976). The paper by Kohl (1905) lists all of the Hymenoptera collected from the surroundings of the snow-capped stratovolcano Mount Erciyes (Erciyes Dag, as Erdschias) of Kayseri Province in Turkey, the highest mountain of central Anatolia. Bee localities visited by the expedition include Bos Tepe and Ewlije-Dagh south of Kayseri and Yilanli Dag (as Illany-Dagh) west of Kayseri. “Bussara (vel Bussana)” is not listed in the gazetteer introducing the study or in Penther (1906), but is possible Bursa in northwest Turkey (Ebmer 2000). Thus, Rasmussen (2012) should be amended to reflect that Vachal described 791 new species (not 786). In addition Table 2 listing the collectors of specimens described by Vachal as new taxa should be amended to include: Penther, Arnold (1865–1931): Turkey (Erciyes and vicinity, “Bussara (vel Bussana)?” (probably Bursa)).
A new species of Leptolalax (Anura: Megophryidae) from the western Langbian Plateau, southern Vietnam
Authors: POYARKOV NIKOLAY JR. A.
Published: March 2015

We describe a new species of megophryid frog from Loc Bac forest in the western part of the Langbian Plateau in the southern Annamite Mountains, Vietnam. Leptolalax pyrrhops sp. nov. is distinguished from its congeners by a combination of the following morphological attributes: (1) presence of distinct dark brown/black dorsolateral markings, including blackish spots on flanks and dark canthal and/or temporal streaks; (2) rudimentary webbing on toes; (3) tympanum externally distinct; (4) dorsal skin finely shagreened with numerous small tubercles and pustules; (5) medium size for the genus (30.3–33.9 mm in 2 adult males, 30.8–34.3 mm in 7 females); (6) grey-pinkish to dark brownish-violet chest and belly with numerous whitish speckles, also covering the lateral sides of body; (7) ventrolateral glands small, indistinct, do not form a distinct line; (8) pectoral glands comparatively small, comprising 1–3% of adult SVL; (10) iris bicolored, typically bright orange-red in upper two-thirds, fading to silvery green in lower third. The male advertisement call of the new species is also unique among those Leptolalax species for which calls are known, with a single long 'introductory' note, consisting of 5–12 pulses, followed by of 4–5 predominantly single-pulsed notes, and an average dominant frequency of 1.91–2.23 kHz. From the morphologically similar L. applebyi, L. melicus and L. bidoupensis, Leptolalax pyrrhops sp. nov. can be further distinguished by 13.5%, 13.7% and 10.3% sequence divergence at the 16S rRNA mtDNA gene. At present, the new species is known from montane evergreen forest between 800–1100 m elevation. We suggest the species should be considered as Data Deficient following IUCN’s Red List categories. To date our finding represents the southernmost known record of the genus Leptolalax from Vietnam.
New Chinese species of the genus Thalassaphorura Bagnall, 1949 (Collembola: Onychiuridae)
Authors: SUN XIN , LI YU
Published: March 2015

Thalassaphorura is the most diverse genus in China so far. Three new species (T. guangdongensis sp. nov., T. xihuensis sp. nov. and T. linzhiensis sp. nov.) are reported from China. T. guangdongensis sp. nov. is characterized by its pso formulae (32/122/33343 dorsally and 11/000/01010 ventrally), 4+4 medial p-chaetae between posterior pso on head, 2+2 chaetae on Abd. I–III terga along axial line and axial chaeta m0 present on Abd. VI tergum. T. xihuensis sp. nov. belongs to the group of species characterized by the presence of only 4 papillae in AIIIO. T. linzhiensis sp. nov. is most similar to T. hainanica Sun, Gao & Potapov, 2014, and differs from the latter by undifferentiated S-chaetae, more vesicles in PAO, two axial chaetae on Abd. VI tergum, the presence of chaetae on Th. I sternum and longer anal spines.
Two new species in the genus Geritola Libert, 1999 (Lepidoptera: Lycaenidae, Epitolini)
Authors: SÁFIÁN SZABOLCS , COLLINS STEVE C. , LIBERT MICHEL , LIBERT MICHEL
Published: March 2015

Two Geritola (Lepidoptera: Lycaenidae) species, closely related to the Central African G. nitidica, have been recognised as new to science. G. wardi sp. n. was captured in small series in Mabira, an eastern outlier forest in Uganda, while G. pacifica sp. n. was discovered in Liberia, in classic Upper-Guinean hyper-wet rainforests. Both of them are described in comparison to their allopatric relative G. nitidica, including male genitalia.
Systematics and biology of mites associated with neotropical hispine beetles in unfurled leaves of Heliconia, with descriptions of two new genera of the family Melicharidae (Acari: Mesostigmata: Gamasina: Ascoidea)
Authors: MORAZA MARÍA L. , LINDQUIST EVERT E.
Published: March 2015

Two new genera Makarovaia and Hispiniphis are described from adults and immatures of newly described species associated with hispine beetles of the genera Chelobasis and Cephaloleia, respectively, occupying unfurled leaves of Heliconia in lowland rainforest of Costa Rica. The new genera share a suite of unique morphological attributes, but are tentatively assigned to the family Melicharidae. While all instars of the mites can be found under the elytra of their adult beetle hosts, adult mites also move freely on and off the beetles. A new form of laboulbeniaceous fungus of the genus Rickia is frequently associated with adult mites of Makarovaia as well as their beetle hosts, yet evidently rarely with mites of a species of Hispiniphis or its beetle hosts which may co-occupy the same host leaves. Limited data suggest considerable host specificity between mites and their beetle hosts. Whether the association of these mites with hispine beetles may be ancient, prior to the beetles’ adaptation to living in unfurled leaves of host plants, or is a more recent invasion and partitioning of the rolled leaf beetle fauna, is discussed.
Advertisement call of Rhinella inopina Vaz-Silva, Valdujo & Pombal, 2012 (Anura: Bufonidae) from the type-locality, northeastern Goiás State, Central Brazil
Authors: DE ANDRADE SHEILA PEREIRA , ROCHA CEZAR FILHO , VICTOR-JUNIOR EDMAR PEREIRA , VAZ-SILVA WILIAN
Published: March 2015

The Rhinella crucifer species group currently comprises six species of toads: R. abei (Baldissera, Caramaschi & Haddad, 2004); R. crucifer (Wied-Neuwied, 1821); R. henseli (A. Lutz, 1934); R. ornata (Spix, 1824); R. pombali (Baldissera, Caramaschi & Haddad, 2004); and, R. inopina Vaz-Silva, Valdujo & Pombal, 2012. Recent genetic studies suggest five species in the R. crucifer species group and show evidence of hybridization between R. crucifer and R. ornata (Thomé et al. 2012).
