Measurement of hybrid-/spl pi/ equivalent circuit parameters of bipolar junction transistors in undergraduate laboratories

In this paper we report on a simple and accurate technique for the measurement of the small-signal y-parameters of a bipolar transistor at a given DC bias using a standard LCR meter which is readily available in undergraduate electronics laboratories. We demonstrate how the hybrid-/spl pi/ equivalent circuit of the transistor can be extracted from the measurement using a spreadsheet. Practical results are presented and the accuracy of the extracted hybrid-/spl pi/ parameters is checked by comparison between PSPICE simulation and actual measurement of the frequency response of a common-emitter amplifier built with the transistor in question.
The Institute of Evolution Wild Cereal Gene Bank at the University of Haifa

The Institute of Evolution Wild Cereal Gene Bank (ICGB) at the University of Haifa, Israel, harbors extensive collections of wild emmer wheat (WEW), Triticum dicoccoides, and wild barley (WB), Hordeum spontaneum, the primary progenitors of wheat and barley, respectively. The ICGB also includes minor collections of 10 species of Aegilops, wild oat (Avena barbata), and Brachypodium stacei and B. hybridum (previously distachyon). Here, we describe the WEW and WB collections, explain sampling strategies, and introduce related studies. Natural populations were sampled across Israel along aridity gradients, occurring from north to south and from west to east, and in local microsites with variable (or contrasting) ecological factors. The collection sites varied greatly in terms of climatic (rainfall, temperature and humidity), edaphic (soil types), and topography (altitude, slope) variables. Thus, the ICGB collections represent wild cereals adapted to a wide range of habitats and eco-geographical conditions. We have collected and preserved these unique gene pools since mid-70th, and further used them for theoretical and applied studies in population genetics, evolution, domestication, adaptation to local and regional habitats, and coping mechanisms for a plethora of biotic and abiotic stresses. Our studies revealed that WEW and WB populations from Israel harbor high adaptive genetic diversity that can serve as a reservoir of beneficial alleles to improve important agronomic traits such as disease resistance, drought tolerance and improved grain protein content. These mostly untapped genetic resources could contribute to increasing world food production for the constantly rising human population.
Advancements and frontiers in nano-based 3D and 4D scaffolds for bone and cartilage tissue engineering

Abstract Given the enormous increase in the risks of bone and cartilage defects with the rise in the aging population, the current treatments available are insufficient for handling this burden, and the supply of donor organs for transplantation is limited. Therefore, tissue engineering is a promising approach for treating such defects. Advances in materials research and high-tech optimized fabrication of scaffolds have increased the efficiency of tissue engineering. Electrospun nanofibrous scaffolds and hydrogel scaffolds mimic the native extracellular matrix of bone, providing a support for bone and cartilage tissue engineering by increasing cell viability, adhesion, propagation, and homing, and osteogenic isolation and differentiation, vascularization, host integration, and load bearing. The use of these scaffolds with advanced three- and four-dimensional printing technologies has enabled customized bone grafting. In this review, we discuss the different approaches used for cartilage and bone tissue engineering.

Insights of Signaling Theory for Acquisitions Research

Abstract This paper examines the use of signaling theory in the M&A context. We review some of the most important developments in applications and extensions of this theory to the realm of M&A, indicating how this theory has been used to explain many M&A decisions and outcomes and has offered fresh perspectives in the mature literature on acquisitions. For example, we show how signaling theory provides a new view of the determinants of acquisition premiums, and it can contribute to an improved understanding of firms’ search for acquisition opportunities as well as target selection. We also provide a critique of existing research to identify gaps in understanding on the roles played by signals. For instance, we discuss how signals can create contracting problems during M&A negotiations, how the value of signals might vary across deals, and how bidder heterogeneity and bidders’ own signals matter for certain transactions. Finally, in addition to taking stock of this stream of research, we identify some of the most important areas that deserve research attention. Signaling theory can contribute to an improved understanding of acquisition performance outcomes, and signals need to be investigated along with other solutions to enhance M&A deal making and execution. We identify new research methods that would help to advance signaling theory in the acquisitions literature.
The in vitro digestion of neutral detergent fibre and other ruminal fermentation parameters of some fibrous feedstuffs in Damascus goat (Capra aegagrus hircus)

Nowadays, global warming negatively influences the production of quality forages especially in arid and semi-arid areas. The eastern Mediterranean Levant region has observed the worst drought for about 900 years (IPCC, 2014). Researchers reported that global warming has caused changes in climate that result in turning semi-humid and semiarid areas into arid areas (Altın et al., 2012). In arid or semi-arid lands, plants turn yellow-brown at the end of the summer and the plant flora of these lands has started to change to steppe or desert-like steppe. Therefore grazing herbivores in arid or semi-arid lands cannot gain required energy and nutrients. In addition, soil types such as sandy and salty constitute also the serious problem to solve (Tuteja, 2007). Therefore, animal nutritionists have been seeking ABSTRACT. The study aimed to compare in vitro gas and methane production and ruminal fermentation patterns of lucerne hay (Medicago sativa L.), sugar beet pulp (Beta vulgaris L.), maize silage (Zea mays L.), plantago hay (Plantago lanceolata L.), ajuga hay (Ajuga bombycina L.), guelder-rose leaf (Viburnum opulus L.), tomato pomace (Solanum lycopersicum L.), Jerusalem artichoke hay (Helianthus tuberosus) and pomegranate peel (Punica granatum L.) in rumen fluid of Damascus goats. Ruminal fermentation parameters such as kinetics, gas production, organic matter digestibility-gas (OMdgas), true-dry matter digestibility (T-DMd), true-organic matter digestibility (T-OMd), true-neutral detergent fibre digestibility (T-NDFd), partitioning factor (PF24) and gas yield (GY24) and metabolizable energy (ME) were determined. The highest gas production from insoluble fraction (bgas) and potential gas production (a+b)gas were in tomato pomace (P < 0.001). The (bgas) and (a+b)gas values of plantago, ajuga and Jerusalem artichoke hays were higher than those of lucerne hay (P < 0.001). The T-DMd, T-OMd, T-NDFd, OMdgas, ME and methane values of tomato pomace and sugar beet pulp were the highest in tested forages (P < 0.01). The highest acetic acid concentration in fermentation fluid was in Jerusalem artichoke hay and maize silage; the molarities of volatile fatty acids in fermentation fluids were ranged from 91.84 to 104.21 (P < 0.001). It can be concluded that tomato pomace and sugar beet pulp have the digestive potential in the goat rumen, although they promote high methane production. Moreover, hays of plantago, ajuga and Jerusalem artichoke as well as pomegranate peels may be used as alternative forages to common fibrous feedstuffs like lucerne hay in goat nutrition.

COMMENTS ON 'ON RULE ORDERING IN BENGALI PHONOLOGY'*

This elaborates Dey's (1979) proposals for writing an N-specification rule for Bengali by bringing in more data to show that his analysis runs into serious problems, and that one has to formulate a g-deletion rule to take care of the counterexamples. It is also shown that there are stronger arguments in support of blurring the distinction between Lexical Redundancy Rules and Phonological Rules in Bengali than Dey had thought of. A detailed discussion of two redundancy rules (S-specification and # CC- simplification) and seven phonological rules (De-gliding, Metathesis, g-deletion, y/w-assimilation, Stress-displacement-cum-vowel- deletion and others) is undertaken to show that LR rules in Bengali must be crucially ordered with respect to P rules. Finally, the arguments in favour of doing away with the intermediate level of Phonological Representation are presented, and the resultant Revised Generative Phonological model is compared with Generative Semanticists' simplification of the grammatical component. The problem in Bengali phonology dealt in Dey ( 1979 ) is of interest to generative phonologists in general and to phonologists working on Bengali in particular because if one could show that both his data and analysis were adequate (and correct), it would have far-reaching consequences for the theory and organization of generative phonology. In what follows, I would elaborate his proposal bringing in more data from Bengali as well as a few more phonological rules of this language to show that �� Dey's ( 1979: 25, 28, 31) analysis of N Specification and related problems is at best partially correct, ��� that a large amount of data escaped his notice, and ���� that there are stronger arguments for blurring the distinction between Lexical Redundancy Rules (henceforth, LR rules) and Phonological Rules (henceforth, P rules) in Bengali than Dey (1979) had thought of. However,, before we go into a detailed discussion of these problems, it may be mentioned here Dey has more or less messed up the transcription of Standard Colloquial Bengali words (probably because of his mother-dialect influence) by putting o and O in wrong places in most of the cases,
The results of an NPK-fertilisation trial of long-term crop rotation on carbonate-rich soil in Estonia

ABSTRACT Soil is an element of crop cultivation that demands consistent fertilisation to compensate for the nutrients that are removed by the harvest. Changes in soil because of prolonged fertilisation can only be estimated by long-term field trials. Experiments in long-term field trial site Kuusiku (since 1965) include crop rotation of potato, late harvest barley, early harvest barley undersown with forage grasses (red clover + timothy), 1-year forage grasses, 2-year forage grasses, and winter rye. Various combinations of mineral and organic fertilisers were used to investigate the yield, soil humus, phosphorus, and potassium content (available and total) of the top- and subsoil. Fertilisation improved the yield of different crops by 1.3–2.6 times; meteorological conditions caused the yield to vary up to 6.4 times. The concentration of humus decreased 0.2% when not using inorganic and organic fertilisers; use of fertilisers increased the concentration of humus by 0.2–0.6%. The humus-rich subsoil (3.5% humus) contained less available phosphorus than humus-poor subsoil (humus 3.0%), which had 29 and 63 mg PDL kg−1, respectively. Grasses in crop rotation enriched the soil with organic matter and reduced the excess of nutrients remaining from previous fertilisation, thereby decreasing nutrient leakage and eutrophication of bodies of water.
Image registration between SAR and TM data using DEM and slant range information

The author has developed a practical method for image registration between SAR images and optical sensor images like Thematic Mapper (TM) images using a digital elevation model (DEM) and slant range information. In this method, first the foreshortening effect by the SAR observation is simulated and applied to a TM image which is overlaid onto DEM. Then the original SAR image is registered to the TM images using the inverse mapping of this foreshortening simulation. The registration errors of 1.9 pixels/3.3 lines for ERS-1/SAR and 2.0 pixels/1.9 lines for JERS-1/SAR are obtained by this method. <<ETX>>
A study of psychological pain in substance use disorder and its relationship to treatment outcome

Substance Use Disorder (SUD) is a major public health concern affecting an estimated 22.5 million individuals in the United States. The primary aim of this study was to characterize psychological pain in a cohort of patients participating in outpatient substance abuse treatment. A secondary aim was to determine the relationships between pre-treatment assessments of psychological pain, depression, anxiety and hopelessness with treatment retention time and completion rates. Data was analyzed from 289 patients enrolled in an outpatient community drug treatment clinic that provides mental healthcare to the underserved. A previously determined threshold score on the Mee-Bunney Psychological Pain Assessment Scale (MBP) was utilized to group patients into high and low-moderate scoring subgroups. The higher pain group reported increased levels of anxiety, hopelessness and depression compared to those in the low-moderate pain group. Additionally, patients scoring in the higher psychological pain group exhibited reduced retention times in treatment and more than two-fold increased odds of dropout relative to patients with lower pre-treatment levels of psychological pain. Among all assessments, the correlation between psychological pain and treatment retention time was strongest. To our knowledge, this is the first study to demonstrate that psychological pain is an important construct that correlates with relevant clinical outcomes in substance abuse treatment. Further, pre-treatment screening for psychological pain may be of benefit in identifying higher-risk patients in need of targeted additional clinical resources to improve treatment retention and completion rates.
Metagenomic DNA sequencing for the diagnosis of intraocular infections

Purpose To compare the performance of unbiased high-throughput sequencing with pathogen directed PCR using DNA isolated from archived ocular fluid, approaches that are compatible with the current sample handling practice of ophthalmologists. Design Retrospective molecular study of banked vitreous samples. Methods We evaluated a metagenomic DNA sequencing-based approach (DNA-seq) using archived positive (n = 31) and negative (n=36) vitreous specimens as determined by reference pathogen-specific PCR assays (herpes simplex virus 1 and 2, cytomegalovirus, varicella-zoster virus, and Toxoplasma gondii). Pathogens were identified using a rapid computational pipeline to analyze the non-host sequences obtained from DNA-seq. Clinical samples were de-identified and laboratory personnel handling the samples and interpreting the data were masked. Results Metagenomic DNA sequencing detected 87% of positive reference samples. In the presumed negative reference samples, DNA-seq detected an additional 6 different pathogens in 8 samples (22% of negative samples) that were either not detected or not targeted with pathogen-specific PCR assays. Infectious agents identified only with DNA-seq were Candida dubliniensis, Klebsiella pneumoniae, human herpesvirus 6 (HHV-6), and human T-cell leukemia virus type 1 (HTLV-1). Discordant samples were independently verified in CLIA-certified laboratories. CMV sequences were compared against the antiviral mutation database and 3 of the samples were found to have mutations conferring ganciclovir resistance. Conclusions Metagenomic DNA sequencing was highly concordant with pathogen-directed PCRs. The unbiased nature of metagenomics DNA sequencing allowed an expanded scope of pathogen detection, including bacteria, fungal species, and viruses, resolving 22% of cases that had previously escaped detection by routine pathogen-specific PCRs. The detection of drug resistance mutations highlights the potential for unbiased sequencing to provide clinically actionable information beyond pathogen species detection.
Sonar reverberation synthesis using nonstationary autoregressive modeling

A method for generating reverberation sequences is proposed. Following the same derivation of S.G. Chamberlain (1983) and J.C. Luby (1983), AR (autoregressive) parameters are computed, AR time-varying parameters are then approximated by a linear combination of time basis functions. This method allows the generation of a reverberation time series with nonstationary spectral characteristics without combining segments according to an overlapped window scheme. The results are illustrated on surface reverberation synthesis. <<ETX>>
Music for an Interactive Network of Microcomputers

In the following article we describe the music presented in concert on July 3rd, 1978 at the Blind Lemon, a small new music gallery in Berkeley, California. In Section I of this article we will give an overview of the piece. In Section II, each of the three composers will present a brief description of their individual program and how that program accepts and sends information to and from the other computers. In Section III we will collectively give our comments on micro-computer network music, a new and useful development which we consider to be a radical departure from traditional music, either of an instrumental or electronic nature.

A Sample WebQuest Applicable in Teaching Topological Concepts.

In recent years, WebQuests have received a great deal of attention and have been used effectively in teaching-learning process in various courses. In this study, a WebQuest that can be applicable in teaching topological concepts for undergraduate level students was prepared. A number of topological concepts, such as countability, infinity, and sets were incorporated into the WebQuest developed. The WebQuest consists of six stages: introduction, task, process, resources, evaluation and conclusion. After the WebQuest activity was applied, the usability of the WebQuest was evaluated, taking into account students’ views. The study was carried out with 29 elementary mathematics pre-service teachers. The data was collected in written form using an interview form that was developed by the researchers. The results indicated that the pre-service teachers have not previously encountered such WebQuest activities however; they display a keen interest in learning about this technology-aided activity and the opportunities to use it in their further lessons.
Neural, functional, and aesthetic impacts of spatially heterogeneous flicker: A potential role of natural flicker

Spatially heterogeneous flicker, characterized by probabilistic and locally independent luminance modulations, abounds in nature. It is generated by flames, water surfaces, rustling leaves, and so on, and it is pleasant to the senses. It affords spatiotemporal multistability that allows sensory activation conforming to the biases of the visual system, thereby generating the perception of spontaneous motion and likely facilitating the calibration of motion detectors. One may thus hypothesize that spatially heterogeneous flicker might potentially provide restoring stimuli to the visual system that engage fluent (requiring minimal top-down control) and self-calibrating processes. Here, we present some converging behavioral and electrophysiological evidence consistent with this idea. Spatially heterogeneous (multistable) flicker (relative to controls matched in temporal statistics) reduced posterior EEG (electroencephalography) beta power implicated in long-range neural interactions that impose top-down influences on sensory processing. Further, the degree of spatiotemporal multistability, the amount of posterior beta-power reduction, and the aesthetic responses to flicker were closely associated. These results are consistent with the idea that the pleasantness of natural flicker may derive from its spatiotemporal multistability that affords fluent and self-calibrating visual processing.
