Wood discrimination analyses of Pterocarpus tinctorius and endangered Pterocarpus santalinus using DART-FTICR-MS coupled with multivariate statistics

Pterocarpus santalinus, listed in CITES Appendix II, is an endangered timber species as a result of illegal harvesting due to its high value and commercial demand. The growing demand for P. santalinus and timbers with the morphologically similar Pterocarpus tinctorius has resulted in confusion as well as identification problems. Therefore, it is of vital importance to explore reliable ways to accurately discriminate between P. santalinus and P. tinctorius. In this study, the method of direct analysis in real time and fourier transform ion cyclotron resonance mass spectrometry (DART-FTICR-MS), combined with multivariate statistical analysis, was used to extract chemical information from xylarium wood specimens and to explore the feasibility of distinguishing these two species. Significant differences were observed in their DART-FTICR-MS spectra. Orthogonal partial least square-discriminant analysis (OPLS-DA) showed the highest prediction, with an accuracy of 100%. These findings demonstrate the feasibility of authenticating wood types using DART-FTICR-MS coupled with multivariate statistical analysis.
Yield, Quality, and Performance of Organic Sweetpotato Slips Grown in High Tunnel Compared with Open Field

Sweetpotatoes (Ipomoea batatas) are nutritious, easily stored, and well adapted to a variety of organic farming operations. This widely consumed root crop is propagated through the use of cuttings, known as slips. Slips are commercially grown primarily in the southeastern United States, and growers in the central United States still have limited access to sweetpotato planting material. Production of organic slips in high tunnels (HTs) could be a profitable enterprise for growers in the central United States given the season extension afforded by controlled-environment agriculture, which could allow growers to diversify their operations and facilitate crop rotation. In trials conducted in 2016 and 2017 at two research stations in northeast and south central Kansas, a systems comparison was used to evaluate the yield and performance of organic sweetpotato slips grown in HT as compared with the open field (OF), with four to six replications at each location. Propagation beds planted with ‘Beauregard’ seed roots in 2016 and ‘Orleans’ in 2017 were established in HT and OF under similar cultural methods and planting schedules. Slips were harvested from both treatment groups and transplanted to field plots to investigate the impact of production system on transplant establishment and storage root production. Slip yield from HT was greater than OF at both locations in 2016 (P ≤ 0.001), but this trend was inconsistent in 2017. Slips grown in HT were on average 12% less compact (slip dry weight per centimeter length) with fewer nodes than their OF counterparts in 2016. Nonetheless, mean comparisons for vine length, stem diameter, and total marketable storage root yield were not significant between HT and OF treatments (1.7 and 2.1 lb/plant, respectively). Similarly, the number of marketable storage roots for HT and OF groups was comparable (3.4 and 3.8 storage roots/plant, respectively). Although more research is needed to evaluate the feasibility of slips grown in HT and to determine recommendations for seed root planting densities, results from this study suggest that HT organic sweetpotato slip production could be a viable alternative to OF production as it relates to slip performance. According to this study, HT production could be a useful mechanism for growing sweetpotato slips, which could provide regional growers more control over planting material. Furthermore, HT slip production could promote the adoption of an underused vegetable crop that can be grown throughout many parts of the United States.
Pandemic Shock and the World after Crisis

Coronavirus pandemia of 2020 turned to be a strong external shock for the modern global financial and economic systems It triggered a virtual cliff of many world markets, especially crude oil production and consumption COVID-19 also revealed serious shortcomings of public health systems and week governments' preparedness to virus epidemics, as well as different degrees of the ability to overcome resulting crisis Evidently, the world will eventually recover However, the process will be slow and complicated Deep structural and institutional changes will be needed Coronacrisis accelerated many emerging trends and developments in technologies, labor markets, and corporate governance Social isolation gave a powerful boost to IT, telecommunication, digital platforms, and gig economy Remote work model demonstrated its efficiency for high skill professionals in financial, legal services, consulting and education At the same time, low skilled jobs with limited remote access possibilities are likely to face growing troubles and declining incomes This will further aggravate problems of inequality and lack of social cohesion As for the international scene, there are already clear evidences of intensifying "bi-polar disorder" between USA and China This is a highly dangerous trend that will seriously hamper the global post-crisis revitalization As for the European Union, the coronavirus crisis highlighted the fragility of its currently existing architecture, namely the fundamental asymmetry between Europeanization of values and nationalization of interests Attempts to convert values into a sort of formal regulations like Schengen or Maastricht naturally meet the challenge from deeply enrooted human identities The EU needs either to make a decisive move towards unified budget or to rollback to more loose association In the nearest future we will see what type of adjustment is politically feasible During and after Covid-19 crisis an underlying trend emerged for re-focusing business activities and consumer demand towards intangible, non-material production and consumption The resources for this type of post-crisis development are intellectual and creative, as well as alternative non-carbon, thus they are basically renewable and unlimited Summing up, the authors suggest that societal and economic growth trajectories will be shifting towards the paradigm of responsible development
Parasitism of frozen Halyomorpha halys eggs by Trissolcus japonicus: applications for rearing and experimentation

ABSTRACT The brown marmorated stink bug, Halyomorpha halys (Stål), has become a well-known pest to growers and homeowners since its 1996 introduction to the United States. A classical biocontrol programme is under development using the egg parasitoid Trissolcus japonicus. Widespread implementation of biocontrol requires efficient mass rearing, which is constrained by the availability of fresh H. halys eggs. In this study, parasitism rate, developmental time, sex ratio and size were compared between wasps reared on fresh versus frozen, newly laid (<1 d old) versus variably aged (0–3 d old), and frozen egg masses stored ≤4 y. Frozen eggs yielded 56–65% fewer wasps, with parasitism rate decreasing 1–3% per month stored. Parasitism rate, sex ratio and developmental time were comparable between newly laid and variably aged eggs. Freezing eggs for any duration did not affect sex ratio or weight of emerged wasps, but delayed emergence 5–6 d. To simulate deployment of sentinel eggs in the field, we incubated frozen eggs at 20°C and 30°C for 1–9 d before exposing them to T. japonicus, then evaluated parasitism trends. Trissolcus japonicus parasitism rate decreased 5–8% per day incubated, unhatched wasps increased 9% per day incubated and sex ratio was not impacted. Variably aged, frozen and longer stored eggs can be used for T. japonicus rearing and experimentation without affecting emerged wasp sex ratio or size within one generation, but have lower parasitism and slower development. Frozen sentinel eggs are effective <3–5 d, especially in hot conditions.
A Switching Control Strategy Based on Switching System Model of Three-Phase VSR Under Unbalanced Grid Conditions

The power electronic converters are typical nonlinear systems. The conventional linearized modeling methods cannot accurately describe the working process of the converter. The control strategies based on the linearized model can only achieve good performance near the working point. By considering the switching nonlinear system nature of the converters, the main contributions of this article are as follows: a current error switching model is developed for the three-phase voltage source rectifiers (VSRs) under unbalanced grid for the first time; and an improved stability analysis theorem is proved for the switching control of the three-phase VSRs under unbalanced grid condition. These contributions are used to design a simple current switching controller for VSRs. The main advantages of the proposed modeling and control strategy are as follows. The switching model of the converter is built without any approximation. It accurately describes the physical working principle of the three-phase VSR under unbalanced grid condition. The proposed current switching controller has a very simple control structure. The switching states of the converter are directly produced according to the switching rule. There are no control parameters, no complicated rotation transformation, and no voltage vector modulation in the proposed switching controller. The proposed switching controller is not sensitive to the circuit parameters. The robustness of the control system is improved without any extra compensators or observers. Simulation and experiment verifies the correctness, the effectiveness, and the superiority of the proposed theory and methodology.
Towards understanding the approximation of Boolean functions by nonclassical polynomials

OF THE DISSERTATION Towards understanding the approximation of Boolean functions by nonclassical polynomials By ABHISHEK BHRUSHUNDI Dissertation Director: Swastik Kopparty The representation and approximation of Boolean functions by polynomials is an important area of research in theoretical computer science, having numerous applications in circuit complexity, communication complexity, pseudorandomness, quantum computation, learning theory, algorithm design, and explicit combinatorial constructions. Results of Green and Tao [GT09], Lovett et al. [LMS11], and Tao and Ziegler [TZ12], on the Inverse Conjecture for the Gowers norm over finite fields of low characteristic, and the subsequent work of Bhowmick and Lovett [BL15], suggest that a potential barrier to the resolution of some of the outstanding open problems in this area is the class of nonclassical polynomials and its ability to nontrivially represent and approximate Boolean functions. Motivated by these works, in this dissertation, we investigate the ability of nonclassical polynomials to approximate Boolean functions with respect to both previously studied and new notions of approximation:
Molecular and morphological identification of Phylloderma stenops Peters, 1865 (Chiroptera, Phyllostomidae) and new records for Colombia

Based on revisionary work of recently collected material in Colombian museums we confirm the presence of Phylloderma stenops Peters, 1865 in 6 new localities for the country, including the first record of the species in the dry lowlands of the northern Caribbean coast, and the increase by more than 800 m of the elevational range of the species in Colombia. DNA-barcoding confirmed our morphological identification, and supported a paraphyletic composition of the cis-Andean populations. Our records exemplify the little knowledge on the ecogeographic distribution of this species and provide further evidence to consider this as a widespread but rare species.
First-principles calculations for electronic, optical and thermodynamic properties of ZnS

The electronic, optical and thermodynamic properties of ZnS in the zinc-blende (ZB) and wurtzite (WZ) structures are investigated by using the plane-wave pseudopotential density functional theory (DFT). The results obtained are consistent with other theoretical results and the available experimental data. When the pressures are above 20.5 and 27GPa, the ZB-ZnS and the WZ-ZnS are converted into indirect gap semiconductors, respectively. The critical point structure of the frequency-dependent complex dielectric function is investigated and analysed to identify the optical transitions. Moreover, the values of heat capacity CV and Debye temperature Θ at different pressures and different temperatures are also obtained successfully.
Stereotactic electroencephalography in humans reveals multisensory signal in early visual and auditory cortices

Unequivocally demonstrating the presence of multisensory signals at the earliest stages of cortical processing remains challenging in humans. In our study, we relied on the unique spatio-temporal resolution provided by intracranial stereotactic electroencephalographic (SEEG) recordings in patients with drug-resistant epilepsy to characterize the signal extracted from early visual (calcarine and pericalcarine) and auditory (Heschl’s gyrus and planum temporale) regions during a simple audio-visual oddball task. We provide evidences that both cross-modal responses (visual responses in auditory cortex or the reverse) and multisensory processing (alteration of the unimodal responses during bimodal stimulation) can be observed in intracranial event-related potentials (iERPs) and in power modulations of oscillatory activity at different temporal scales within the first 150 ms after stimulus onset. The temporal profiles of the iERPs are compatible with the hypothesis that MSI occurs by means of direct pathways linking early visual and auditory regions. Our data indicate, moreover, that MSI mainly relies on modulations of the low-frequency bands (foremost the theta band in the auditory cortex and the alpha band in the visual cortex), suggesting the involvement of feedback pathways between the two sensory regions. Remarkably, we also observed high-gamma power modulations by sounds in the early visual cortex, thus suggesting the presence of neuronal populations involved in auditory processing in the calcarine and pericalcarine region in humans.
Parallel genomic evolution of parasite tolerance in wild honey bee populations

Sudden biotic pressures, such as those from novel diseases and pathogens, require populations to respond rapidly or face potential extinction. How this response process takes place remains poorly understood, particularly in natural environments. In this study we take advantage of unique decade-long data sets of two wild honey bee (Apis mellifera) populations in the United States to reconstruct the evolution of tolerance to a novel parasite, the ectoparasitic mite Varroa destructor. Upon the arrival of Varroa, the two geographically isolated populations simultaneously suffered massive Varroa-induced mortality, but stabilized within two years. Here we sequenced and phased genomes of 465 bees sampled from both populations annually over the decade that spanned Varroa’s arrival. Remarkably, we found that genetic changes were strongly correlated between the populations, suggesting parallel selective responses to Varroa parasitization. The arrival of Varroa was also correlated with an influx of genes of African origin into both populations, though surprisingly it did not substantially contribute to the overall similarity of the evolutionary response between them. Genes involved in metabolic, protein processing and developmental pathways were under particularly strong selection. It is possible that interactions among highly connected gene groups in these pathways may help channelize selective responses to novel parasites, causing completely unrelated populations to exhibit parallel evolutionary trajectories when faced with the same biotic pressure. Our analyses illustrate that ecologically relevant traits emerge from highly polygenic selection involving thousands of genes contributing to complex patterns of evolutionary change.
Hospitality and tourism research rankings by author, university, and country using six major journals: The second decade of the new millennium

Park, Cater, and Abbott (2011) published a paper on Journal of Hospitality and Tourism Research, which has been widely used as a benchmark for ranking the research performance of the hospitality and tourism management (HTM) programs in the universities across the world. In the first decade of the millennium (2000-2009), the hospitality and tourism industry had developed vigorously, and research in this field had emerged rapidly (Park, Cater & Abbott, 2011). During that time period, many journal articles were contributed by universities such as Cornell and from countries such as United States (Park et al., 2011). Park et al. (2011) examined the geographic distribution of the most productive researchers contributing most to the top-tier hospitality and tourism journals. The result indicated that some countries were underrepresented such as France, Germany and Russia. And many of the research papers addressed the importance of Asia-Pacific region and particularly on China (Shen et al., 2018). At the end of the paper, the authors suggested that future studies apply the same method to review the trend of hospitality and tourism research again. This study aimed to fulfill this research goal. This study aimed to examine the current status of hospitality and tourism research during 2010-2019 with the same method provided by Park et al. (2011) and further compare the results to show the trends and changes between the two decades.
Robustness to Large-Scale Mass Production Manufacturing Tolerances by Means of Sensitivity and Statistical Analysis for IPMSMs

This article deals with highlighting some pragmatic approaches for determining the key-parameters that one has to monitor in order not to jeopardize the fulfillment of the customer specifications, due to the tolerances, that occur in large-scale mass production. For that, two parametrization models (symmetric vs. asymmetric) and two types of parameter distributions (uniform vs. normal) are compared when considering lamination, stack assembly and material properties tolerances. Results in different scenarios for both the motor (in open-circuit and under load), and the whole drive (with and without position sensor detection errors) are provided and compared with end-of-line measurements (where available) for a 12-slots 10-poles IPM-type PMSM with fractional slot concentrated winding. After including the effect of the temperature in the full asymmetric model, rather good agreements between calculations and measurements are reported for back-EMF and torque constant. Furthermore, it is shown that the interaction between the uncertainties of the motor parameters and the rest of the drive's components (e.g. position sensor) cause large inaccuracies into the system, and they are hardly predictable by taking the individual deviations separately. Finally, towards the end, attempts are made to reduce the computational and the modeling effort using various techniques and ultimately fitted artificial neural networks (ANNs) as surrogates.
The Occupational Therapy Examination and Practice Preparation (OTepp) Program: Development, Implementation and Evaluation of an Educational Program for Internationally-Educated Occupational Therapists

This paper provides a chronological overview of the development, implementation, and evaluation of an educational initiative aimed at ensuring internationally-educated occupational therapists are prepared to enter practice in their new country, Canada. The three major phases of the program’s 12-year evolution are described, to distill the key lessons learned at each phase. Data related to the demographics of participants, program content, results of the national examination, registration, and employment outcomes are included. An enhanced understanding of the transition experience of internationally educated occupational therapists provides a strong foundation from which to support internationallyeducated colleagues and strengthen the occupational therapy profession.
Minimally Invasive Partial Nephrectomy in the Era of Robotic Surgery

Objectives: The objectives of the study were to compare the operative features, complication rates, functional, and pathological outcomes of laparoscopic partial nephrectomy (LPN) and robotic-assisted partial nephrectomy (RPN). Methods: The demographics, perioperative, and follow-up data of patients who underwent partial nephrectomy between January 2007 and April 2020 with minimally invasive methods were retrospectively analyzed. Patients with minimum 3 months follow-up were enrolled in the present study. Perioperative and pathological outcomes were compared between the patients underwent LPN and RPN. Results: A total of 85 patients (65 LPN and 20 RPN) were included in the present study. The mean patient age at the time of surgery was 56.31±10.48 years. Female-to-male ratio was 30/55. Patients in the RPN group had higher R.E. N.A. L. and PADUA scores (p=0.039 and p=0.030, respectively). Median warm ischemia time, median operation time, median intraoperative estimated blood loss, mean post-operative hemoglobin change, and median hospitalization time were similar between groups (p=0.133, p=0.753, p=0.079, p=0.882, and p=0.473, respectively). Artery-only clamping rate was significantly higher in RPN group (p=0.033). The cost of RPN was significantly greater than LPN (p<0.001). Transfusion rates, post-operative complication rates, percent of estimated glomerular filtration rate change at the last follow-up, and trifecta achievement were similar between the groups (p=0.622, p=0.238, p=0.428, and p=0.349, respectively). Conclusion: In this series, similar perioperative and functional outcomes were achieved by RPN compared to LPN in more complex renal masses.
Wideband Array-Fed Fabry-Perot Cavity Antenna for 2-D Beam Steering

We propose the design and testing of a 2-D Fabry–Perot structure based on a multilayer (ML) slab arrangement fed by a circular array of simple sources. Such a class of planar leaky-wave (LW) antenna can be made of low-loss commercial laminates, and it is bounded on top by a subwavelength partially reflecting surface. The antenna is designed to suppress undesired radiation from the quasi-TEM mode while leaking power by the excitation of a fast TM1 leaky mode, which is a perturbed version of the guided-wave supported by the corresponding parallel-plate waveguide. An accurate dispersive analysis for the ML structure is developed, and an original feeding system is designed and optimized to provide the needed wideband impedance matching. Thanks to translational invariance enabled by the homogenized nature of the partially reflecting screen, the antenna is used as a radiating element in the design of a LW-enhanced phased array, constituted by an arrangement of vertical probes to generate directive pencil beams steerable at a single frequency in azimuth and by changing frequency in elevation.
Impact of different modes of pollination on the productivity of Indian mustard (Brassica juncea L.) in Punjab

A significant effect of planned pollination was observed on quality and quantity of Brassica juncea var. PBR-357 yield. The mean number of pods per plants, number of seeds per plants, siliqua length, thousand seed weight and oil content during 2018-19 and 2019-20 was significantly highest in Planned pollination with A. mellifera (223.6 pods/plant and 224.92 pods/plant, 16.26 seeds/pod and 16.79 seeds/pod, 5.71 cm and 5.66 cm, 5.23 gm and 5.125 gm and 41.01%, respectively) followed by open pollination (176.5 pods/plant and 179.8 pods/plant, 14.36 seeds/pod and 13 seeds/pod, 5.39 cm and 5.46 cm, 4.84 gm and 4.93 gm and 37.99%, respectively) and pollinators’ exclusion (146.87 pods/plant and 152.39 pods/plant, 10.67 seeds/pod and 10.72 seeds/pod, 4.88 cm and 4.60 cm, 4.11 gm and 4.17 gm and 25.98%, respectively) during 2018-19 and 2019-20 on Brassica juncea var. PBR-357.
