Regularized theta liftings and periods of modular functions
Authors: Bruinier Jan H. , Funke Jens , Imamoḡlu Özlem 
Published: June 2013

Abstract

In this paper, we use regularized theta liftings to construct weak Maass forms of weight 1/2 as lifts of weak
Maass forms of weight 0. As a special case we give a new proof of some of recent results of Duke, Toth and the third author
on cycle integrals of the modular j-invariant and extend these to
any congruence subgroup. Moreover, our methods allow us to settle the
open question of a geometric interpretation for periods of j along
infinite geodesics in the upper half plane. In particular, we give the
`central value' of the (non-existent) `L-function' for j. The key to
the proofs is the construction of a kind of simultaneous Green
function for both the CM points and the geodesic cycles, which is
of independent interest.
The nuclear receptor peroxisome proliferator-activated receptor-γ promotes oligodendrocyte differentiation through mechanisms involving mitochondria and oscillatory Ca2+ waves

Published: June 2013

Abstract
Peroxisome proliferator-activated receptor-γ (PPAR-γ) is one of the most studied nuclear receptor since its identification as a target to treat metabolic and neurological diseases. In addition to exerting anti-inflammatory and neuroprotective effects, PPAR-γ agonists, such as the insulin-sensitizing drug pioglitazone, promote the differentiation of oligodendrocytes (OLs), the myelin-forming cells of the central nervous system (CNS). In addition, PPAR-γ agonists increase OL mitochondrial respiratory chain activity and OL’s ability to respond to environmental signals with oscillatory Ca2+ waves. Both OL maturation and oscillatory Ca2+ waves are prevented by the mitochondrial inhibitor rotenone and restored by PPAR-γ agonists, suggesting that PPAR-γ promotes myelination through mechanisms involving mitochondria.
Die Trasjanka und die Regiolektalisierung des Russischen in Weißrußland
Authors: Stern Dieter 
Published: June 2013

Abstract
Though a wealth of literature on Russian-Belorusian bilingualism and more specifically on Trasjanka has been published within recent years, the status of Trasjanka is still some matter of debate. None of the labels which have been proposed so far, seem to hit the mark. In this article it will be argued that the search for a label which will make sense, has been hampered by the fact that the language situation in Belorussia is still being interpreted in terms of bilingualism. By comparing the Belorusian situation to what is simultaneously going on in most Western European countries, among them Germany, it is hoped to demonstrate that what is going on in Belarus is more akin to processes of destandardisation and concurrent dialect-leveling and -death in monolingual dialect-standard-continua. It will also be argued that this parallel ought to be taken at face value, which implies that Russian-Belorusian bilingualism is in fact dialectal in nature and that Trasjanka is ultimately just another of the many regiolects of increasingly decentralising modern Europe.
Muscle function and quality of life are not impaired in familial hypocalciuric hypercalcemia: a cross-sectional study on physiological effects of inactivating variants in the calcium-sensing receptor gene (CASR)
Authors: Jakobsen Niels Frederik Breum , Rolighed Lars , Nissen Peter H , Mosekilde Leif , Rejnmark Lars 
Published: June 2013

BackgroundFamilial hypocalciuric hypercalcemia (FHH) is often due to inactivating variants in the calcium-sensing receptor (CASR) gene causing chronically elevated plasma calcium levels with inappropriately normal or elevated parathyroid hormone levels. In patients with primary hyperparathyroidism, the state of hyperparathyroid hypercalcemia is associated with reduced muscle strength and impaired quality of life (QoL).ObjectiveTo study whether FHH affects muscle function, postural stability, and QoL.DesignIn a cross-sectional study, we investigated muscle strength (handgrip, elbow flexion/extension, and knee flexion/extension), balance function, physical activity, and QoL in 50 patients with FHH and in a similar number of age- and gender-matched population-based healthy controls. All but one of the FHH cases had genetically verified inactivating variants in theCASRgene.ResultsStudied subjects (n=100, 68% females) had a mean age of 56.0 years. Muscle strength as assessed by measuring maximum force and maximum force production did not differ between the groups. Neither did groups differ in terms of QoL, physical activity, or postural stability, as assessed during normal standing with eyes open, normal standing with eyes closed, semi-tandem standing, or tandem standing. Adjustment for vitamin D status (plasma 25-hydroxyvitamin D levels) and BMI did not change results.ConclusionDespite a state of chronic hypercalcemia, muscle strength, balance function, and QoL are not impaired in patients with FHH. Our findings are reassuring for patients with FHH as they should not be considered as having a severe disease.
The Integration of Women and Minorities into the Auditing Profession since the Civil Rights Period
Authors: Madsen Paul E. 
Published: June 2013

ABSTRACT:
Following the Civil Rights Movement and the “quiet revolution” in women's work over the years from 1950 to 1970, women and minorities increasingly joined the auditing profession while the profession ramped up efforts to encourage integration. The purpose of this study is to rigorously examine how the integration of auditors has evolved since the civil rights and quiet revolution period. The primary distinctive feature of this study is that it evaluates the auditing profession's integration by comparing it to samples of occupations similar to auditing for the purpose of isolating auditing-specific forces influencing integration. I find that the pay structure in auditing is unusually equal, consistent with “equal pay for equal work.” The results for women, Hispanics, and miscellaneous minorities are consistent with members of these groups responding as one might expect to equal pay in auditing: groups that are poorly paid in other occupations select into auditing at higher rates, and groups that are well paid in other occupations select out of auditing at higher rates. The results for blacks are anomalous in that their pay in auditing has been good relative to many comparable occupations, but they have nevertheless been poorly represented in auditing. There are a number of theories that could potentially explain why blacks may be anomalously underrepresented in auditing. To begin to test them, I perform an exploratory analysis of the representation of women and minorities among college freshmen, college graduates, and young auditors. The results suggest that accounting is a popular degree among black college freshmen and that a relatively high percentage of accounting graduates are black. However, although they are well represented in the pool of potential new auditors, black accounting graduates enter the auditing profession at very low rates relative to other occupations requiring levels of education similar to auditing. The results suggest that black underrepresentation in auditing is not due to a lack of awareness among, or role models for, young blacks.

Summary
Background: Episodic fever syndromes are commonly seen in pediatric practice. Episodic fever of unknown origin (FUO) lasts for a few days or weeks and is followed by a fever-free period with a sense of well-being. In this condition, activated neutrophils and monocytes intensively generate reactive oxidative species that may further damage various mole- cules. The aim of the study was to evaluate oxidative stress biomarkers, lipid peroxidation in erythrocytes and plasma, and advanced oxidation protein products (AOPP) in children with episodic FUO.
Methods: The study enrolled 25 children with episodic FUO in afebrile phase and 25 healthy children as controls. Lipid peroxidation was evaluated by measuring malondialdehyde (MDA) production with the thiobarbituric-acid-reactive sub- stances (TBARS) assay in erythrocytes and plasma. Oxidative modification of proteins was measured spectrophotometri- cally by the determination of AOPP in plasma.
Results: Mean duration of episodic fevers was 3.96±2.8 years. Erythrocyte MDA levels were higher in children with FUO than in controls (86.26± 10.75 vs. 78.0±3.21 nmol/g hemoglobin), although not significantly (p=0.202). The MDA plasma concentrations were similar (2.42±0.35 vs. 2.41 ±0.39 (xmol/L) between the groups (p=0.732). Unexpectedly, levels of AOPP were significantly lower in chil- dren with FUO than in healthy controls (18.8±5.04 vs. 25.1 ±3.35 nmol/L, p=0.047).
Conclusions: Episodic fevers of unknown origin with an aver- age duration of 3.96±2.8 years do not cause significant oxidative modifications of lipids and proteins in children.
Parasitoid complex and bionomics ofApanteles polychrosidis(Hymenoptera: Braconidae) on the ash leaf-cone roller (Lepidoptera: Gracillariidae)
Authors: Wist T.J. , Evenden M.L. 
Published: June 2013

AbstractThe ash leaf-cone roller,Caloptilia fraxinella(Ely) (Lepidoptera: Gracillariidae) is an introduced leaf-mining moth of horticultural ash trees (FraxinusLinnaeus; Oleaceae) in Western Canadian Prairie cities. Here, we identify the dominant parasitoid of this leaf-mining moth asApanteles polychrosidisVierek (Hymenoptera: Braconidae) and document its emergence pattern, courtship, mating, and host acceptance behaviours.Apanteles polychrosidisadult emergence is protandrous and mating occurs soon after female emergence. MaleA. polychrosidiscan mate multiple times in short sequence with a mean copulation time of 49 seconds. It is likely thatA. polychrosidisoverwinters in an alternate larval host, after emergence fromC. fraxinella. Mated femaleA. polychrosidisreadily parasitise an alternate host, the obliquebanded leafroller (Choristoneura rosaceana(Harris); Lepidoptera: Tortricidae), known to overwinter as larvae. Through rearingC. fraxinellapupae, we describe the remainder of the parasitoid complex ofC. fraxinella, in order of parasitism rate, asDiadegmaFörster (nearDiadegmafenestrale(Holmgren)) (Hymenoptera: Ichneumonidae), threeSympiesisFörster species (Hymenoptera: Eulophidae) (Sympiesissericeicornis(Nees von Esenbeck), one nearSympiesisviridula(Thomson) and one unknown species), andPteromalus phycidis(Ashmead) (Hymenoptera: Pteromalidae) and show that severalSympiesisspecies can be hyperparasitic onA. polychrosidis.Caloptilia fraxinelladensity within the tree canopy is highest in the lower canopy. Host density and abiotic factors such as temperature and light intensity do not influence the within-canopy distribution of most parasitoids exceptSympiesisspecies, which preferred the northern canopy.
Different Exercise Training Interventions and Drop-Landing Biomechanics in High School Female Athletes
Authors: Pfile Kate R. , Hart Joseph M. , Herman Daniel C. , Hertel Jay , Kerrigan D. Casey , Ingersoll Christopher D. 
Published: June 2013

Context:
Anterior cruciate ligament (ACL) injuries are common in female athletes and are related to poor neuromuscular control. Comprehensive neuromuscular training has been shown to improve biomechanics; however, we do not know which component of neuromuscular training is most responsible for the changes.

Objective:
To assess the efficacy of either a 4-week core stability program or plyometric program in altering lower extremity and trunk biomechanics during a drop vertical jump (DVJ).

Design:
Cohort study.

Setting:
High school athletic fields and motion analysis laboratory.

Patients or Other Participants:
Twenty-three high school female athletes (age = 14.8 ± 0.8 years, height = 1.7 ± 0.07 m, mass = 57.7 ± 8.5 kg).

Intervention(s):
Independent variables were group (core stability, plyometric, control) and time (pretest, posttest). Participants performed 5 DVJs at pretest and posttest. Intervention participants engaged in a 4-week core stability or plyometric program.

Main Outcome Measure(s):
Dependent variables were 3-dimensional hip, knee, and trunk kinetics and kinematics during the landing phase of a DVJ. We calculated the group means and associated 95% confidence intervals for the first 25% of landing. Cohen d effect sizes with 95% confidence intervals were calculated for all differences.

Results:
We found within-group differences for lower extremity biomechanics for both intervention groups (P ≤ .05). The plyometric group decreased the knee-flexion and knee internal-rotation angles and the knee-flexion and knee-abduction moments. The core stability group decreased the knee-flexion and knee internal-rotation angles and the hip-flexion and hip internal-rotation moments. The control group decreased the knee external-rotation moment. All kinetic changes had a strong effect size (Cohen d &gt; 0.80).

Conclusions:
Both programs resulted in biomechanical changes, suggesting that both types of exercises are warranted for ACL injury prevention and should be implemented by trained professionals.
Robust and Quality Boundary Constrained Tetrahedral Mesh Generation
Authors: Song Songhe , Wan Min , Wang Shengxi , Wang Desheng , Zou Zhengping 
Published: June 2013

AbstractA novel method for boundary constrained tetrahedral mesh generation is proposed based on Advancing Front Technique (AFT) and conforming Delaunay triangulation. Given a triangulated surface mesh, AFT is firstly applied to mesh several layers of elements adjacent to the boundary. The rest of the domain is then meshed by the conforming Delaunay triangulation. The non-conformal interface between two parts of meshes are adjusted. Mesh refinement and mesh optimization are then preformed to obtain a more reasonable-sized mesh with better quality. Robustness and quality of the proposed method is shown. Convergence proof of each stage as well as the whole algorithm is provided. Various numerical examples are included as well as the quality of the meshes.

Published: June 2013

Purpose To discuss the techniques and mechanisms of retinal oximetry with a focus on utilization of retinal oximetry in the assessment of retinal oxygen saturation in glaucoma. Methods We reviewed recent literature found by searching combinations of the following search terms: glaucoma, retinal oximetry, ocular blood flow, retinal blood flow, oxygen saturation. We also reviewed pertinent references from articles found in this search. Results Retinal oximetry offers the potential for directly assessing oxygen saturation in retinal tissue. This capability can contribute to the knowledge of ocular blood flow and its role in the pathogenesis of glaucoma. Conclusions Recent research has shown that retinal oximetry could become an important clinical tool in glaucoma. However, more research is needed to validate the reliability and reproducibility of retinal oximetry, and to fully deduce its clinical role in ocular diseases.

Published: June 2013

Abstract
A rapid ultrasound accelerated sequential extraction (USE) procedure was used to develop chemical partitioning of vanadium (V), proposed by the Community Bureau of Reference/European Union Measurement and Testing Programme (BCR). The effects of ultrasonic treatment on the extraction of V in different soil samples collected from the vicinity of a thermal power plant and agricultural areas of Sindh, Pakistan, were evaluated. In the conventional BCR-sequential extraction method, each extraction step takes 16 h. With the use of ultrasound energy, Steps 1–3 of the USE procedure (excluding the hydrogen peroxide digestion in Step 3, which was performed conventionally) could be completed in 45, 40, and 45 min, respectively. Analysis of the extracts was performed by electrothermal atomic absorption spectrometry. The total contents of V were obtained by digestion with two acid mixtures: H2O2–HF–HNO3–H2SO4 and HClO4–HF–HNO3–H2SO4. Validation was performed by the standard addition technique. Results obtained for each fraction by both methods were statistically compared; no significant differences were found (P &lt; 0.05). The accuracy of the USE procedure was checked by comparing the sum of the V contents in the three fractions and residue with the total content of V. The results of this work provide information on the chemical composition, distribution, and potential mobility of the V in different soils.

Abstract
A simple and time-efficient UV spectrophotometric method was developed for the determination of sucralose in artificial sweeteners. The procedure is based on the UV spectrophotometric determination of the photodegraded product at 270 nm in alkaline medium (pH 12). LOD for this method was 0.02 g/L, and the calibration curve was found to obey Beer's law in the concentration range of 0.1 to 1.2 g/L, with a correlation coefficient (R2) value of 0.9977. The proposed method was studied for accuracy and precision.

Authors: Dmitrovic Jasna , Durden David A 
Published: June 2013

Abstract
An LC/MS/MS method has been optimized and validated for the quantification and confirmation of fumagillin in honey. Fumagillin is isolated and concentrated by RP polymeric SPE. Final extracts are analyzed using electrospray ionization LC/MS/MS in positive mode with a formic acid and ammonium formate–acetonitrile mobile phase. Method uncertainty was determined using two analytical systems from different manufacturers. The validation of this LC/MS/MS method for the detection of fumagillin demonstrated overall recovery of 99.3%, precision of 5.9%, expanded uncertainty of 13.2%, and LOD of 0.368 μg/kg using an Agilent 6410 triple quadrupole system. Robustness testing showed that the method is robust against small changes in the method parameters. The method has been successfully applied to test 30 honey samples received as part of the Canadian Food Inspection Agency inspection program for the presence of fumagillin. It also was externally evaluated through proficiency testing and found to be fit-for-purpose.
Validation of an HPLC Method for the Simultaneous Determination of trans-Lutein, (3R,3′R)-trans-Zeaxanthin, and (3R,3′S)-trans-Zeaxanthin
Authors: Warfield John R , Lewis Brandon J 
Published: June 2013

Abstract
trans-Lutein, (3R,3′R)-trans-zeaxanthin, and (3R,3′S, meso)-trans-zeaxanthin are carotenoid isomers found in the human eye. Trans-lutein and trans-zeaxanthin can be separated under NP chromatographic conditions; however, (3R,3′R)-trans-zeaxanthin and (3R,3′S)-trans- zeaxanthin coelute and require chiral separation techniques. The validation of an HPLC analytical method for the simultaneous determination of trans-lutein, (3R,3′R)-trans-zeaxanthin, and (3R,3′S)-trans- zeaxanthin is described. The method uses a hexanes and 2-propanol gradient on a Daicel AD-H chiral column to separate the carotenoids for detection at 446 and 450 nm. The method was found suitable for use in quantifying the three analytes over a wide range of concentrations with the limiting factor being the upper solubility limit of 14 μg of (3R,3′S)-trans-zeaxanthin/mL of the injection solution of hexane–2-propanol (95 + 5, v/v). The precision of the method, expressed by the coefficient of variation, was &lt;5% for the analytes when triplicate injections were used. The average recoveries ranged between 95 and 103% for standards that were 50 to 200% of the target analyte level. The LOQ in the injection solution was determined to be between 1 and 6 ng/mL for the analytes. The method is valid for the separation and quantification of trans-lutein, (3R,3′R)-trans-zeaxanthin, and (3R,3′S)-trans-zeaxanthin.
Electrochemical Detection of Amaranth in Food Based on the Expanded Graphite Paste Electrode

Published: June 2013

Abstract
A sensitive and simple electrochemical method was developed for successful determination of amaranth in food samples by square-wave adsorptive stripping voltammetry based on an expanded graphite paste electrode (EGPE). The EGPE has strong and sensitive voltammetric responses to amaranth, owing to the multiporous structure and large surface area of EG. The electroanalytical determination of this azo dye was found to be optimal in Britton-Robinson buffer solutions (pH 7.0) under the following experimental conditions: accumulation time, 400 s; accumulation potential, 0.4 V; pulse amplitude, 25 mV; and frequency, 10 Hz. Under the optimum experimental conditions, the oxidation peak current was proportional to the concentration of amaranth over two ranges from 0.01 to 0.1 and 0.1 to 4.0 μM. These linear ranges of the EGPE toward amaranth were wider than other electrodes reported before. The LOD was estimated to be 0.005 μM (S/N = 3:1). The developed method was applied to the determination of amaranth in retsina samples, and the results were confirmed by HPLC. Statistical analysis of these data showed that the results of the two methods compared favorably. This work provides a simple and easy approach to the determination of amaranth in foods with high sensitivity and excellent selectivity.
