A Lightweight, Wideband, Dual-Circular-Polarized Waveguide Cavity Array Designed With Direct Metal Laser Sintering Considerations

A lightweight, wideband, and dual-circular-polarized (CP) waveguide cavity array operating at Ku-band is proposed. To obtain dual-orthogonal linear polarizations (LPs), the basic radiating element is a square cavity fed by two waveguides. By properly tuning the feed networks, equal amplitude and phase of radiated electric field for two orthogonal polarizations can be obtained, culminating in a <inline-formula> <tex-math notation="LaTeX">$16 \times 16$ </tex-math></inline-formula> dual-LP array. A wideband waveguide-based hybrid coupler is integrated with a dual-LP array to achieve the final dual-CP array. The proposed dual-CP array is fabricated by applying the direct metal laser sintering method. Its overall size is 288 mm <inline-formula> <tex-math notation="LaTeX">$\times288$ </tex-math></inline-formula> mm <inline-formula> <tex-math notation="LaTeX">$\times52$ </tex-math></inline-formula> mm, and it has weighted slightly less than 1.3 kg. The measured results show that for both the CP ports, the array has exhibited desirable bandwidth of 12.25–14.5 GHz (at VSWR <2), and its isolation is better than 15 dB. The measured gain ranges from 29.5 to 32.4 dBic, while the axial ratio is better than 4.5 dB over the entire band. A total efficiency of over 60% can be obtained for both the LHCP and RHCP radiations.
Folded Patch Antenna With Tunable Inductive Slots and Stubs for UHF Tag Design

A miniature folded patch with a dimension of <inline-formula> <tex-math notation="LaTeX">$40\,\,\text {mm} \times 40\,\,\text {mm} \times 1.6\,\,\text {mm}\,\,(0.1156\lambda \times 0.1156\lambda \times 0.0046\lambda $ </tex-math></inline-formula> at 867 MHz) is proposed for designing a passive metal-mountable tag. It consists of a square patch which is equally separated into two rectangular patches. Since the patch resonator usually has high resonant frequency, multiple tuning mechanisms are always needed to bring down the frequency so that it can be used for designing a tag antenna in the UHF band. In the proposed design, each patch is incorporated with a C-shaped slot and three thin inductive stubs for performing different levels of frequency tunings. An equivalent circuit has been built for estimating the input impedance of the antenna. Reasonable agreement is found between the measured, modeled, and simulation results. The proposed tag antenna is readable from 5 m with an EIRP of 3.28 W when placed on a 20 cm <inline-formula> <tex-math notation="LaTeX">$\times20$ </tex-math></inline-formula> cm metal plate.
A fully-digital phase modulator with phase calibration loop for high data-rate systems

This paper presents a digital phase modulator for wide bandwidth polar transmitters. It adopts a digital-to-time converter (DTC) and high-speed phase calibration loop that improves sampling rate for the same phase resolution. The DTC consists of a chain delay line with different delay cells to generate a small phase. A feedback loop based on a novel time-to-digital converter (TDC) nested inside the phase modulator sets the DTC output phase accurately across the range of input digital code as well as over process, voltage, and temperature. By using the TDC-based feedback loop, the proposed phase modulator can achieve high sampling rate and small phase resolution. The phase modulator achieves 0.72 degree phase resolution and 40 MS/s sampling rate while consuming 8 mW of power. This phase modulator is implemented in a 180 nm CMOS technology and occupies 0.3 mm2.
Post-transcriptional gene silencing and its implication to the asian soybean rust- a review article

Soybean is one of the most economically important crops in the world. Soybean yield is severely affected by biotic agents, especially by Asian Soybean Rust (ASR). The causal agent of ASR is Phakopsora pachyrhizi; a biotrophic fungus that belongs to Basidiomycota. Chemical control is the most effective control method for ASR, but it is costly. In the past, many soybean varieties resistant to ASR have been developed by introgression of resistance genes (R genes) to local varieties. Since P. pachyrhizi isolates are highly diverse, the resistant varieties are vulnerable to newly evolved pathogen isolates. Until now there is no variety that is resistant to all pathogen isolates. Therefore, there is a need to develop new strategies other than R genes. Identification of new candidate genes that are crucial for fungi in pathogenicity may lead to new options for P. pachyrhizi control. Many interesting genes have been identified but their study is impaired by the biotrophic nature of rust fungi. In this regard RNAi has emerged as a reverse genetic tool. The HIGS method (Host Induced Gene Silencing) is used to down regulate fungal candidate genes in planta. This is an indirect method where the silencing signal is formed in the plant but it mediates RNAi in the fungus.
Is there a place for bioindication in the geographical sciences? A focus on two groups (Carabidae and Araneae)

This paper is a brief review of the current state of Carabidae and Araneae usefulness in indicator-based, geographical science studies. The database of scientific papers on the ISI Web of Science (Elsevier and Springer) was the main source of information. Only papers that considered landscape and addressed human activity in relation to selected taxa were chosen for further analyses. The articles with an explicit ecological character and which showed no potential possibilities for wider application in geographical research were not used. The selected papers were examined with respect to: the leading subject matter, area considered, applications, repetitiveness of the data collecting, and with respect to the aboveground and underground compartments. For clarity’s sake, areas of land cover, land use, and human management were divided into four categories. The categories were ordered from 1 to 4, according to increasingly human-induced pressure starting with (1) areas of a natural state, (2) proceeding to forests, (3) farm land, and (4) finally to urban/suburban. This non-exhaustive review confirms the very broad possibilities of applying selected taxa as indicators in geographical studies. Such an application refers to both the range of possibilities of the study location choice (forest, arable, suburban areas etc.), and the subject matter of the study. Faunistic indicators can supply geographical researchers with quantitative and qualitative data. The data then allow for an estimation of the ecological response, due to the variety of changes taking place in the ecosystem. Faunistic indicators are invaluable tools for indirectly estimating subtle environmental changes. Such changes include those which are the result of a specific interaction between ecosystem components, which are difficult to measure using traditional methods. The impact of human activities can thus be assessed in a much more cost-effective way. A key methodological aspect is to choose the most accurate faunistic groups for the study as well as using standardised method of collecting. It is also important to consider the environmental parameters which have an impact on the selected bioindicators.
Combination Effects of Quercetin, Resveratrol and Curcumin on In Vitro Intestinal Absorption

Objective: Quercetin, resveratrol and curcumin are plant derived natural products that are rapidly gaining popularity as supplements for a wide assortment of conditions including cardiovascular disease, cancer, asthma, diabetes, neurodegeneration, aging and stress. Unfortunately the therapeutic potential of these compounds is limited by their poor intestinal and intracellular bioavailability. Therefore this study sought to examine how combinations of quercetin, resveratrol, and curcumin, with and without piperine, 200 nM, affected an in vitro permeability model using apical-to-basal permeability across intact caco-2 monolayers. Quercetin, resveratrol and curcumin were applied apically alone or in combination at 50 μM and measured in the basal chamber at 30 min. Results: Resveratrol received the greatest enhancement in permeability when combined with other agents: quercetin (310%), curcumin (300%), quercetin and curcumin (323%, 350% with piperine). Curcumin also demonstrated increased permeability when combined with quercetin alone (147%) and both quercetin and resveratrol (188%), addition of piperine resulted in a 229% increase in permeability. Quercetin permeability was not significantly affected using any combination, but showed maximal permeability when combined with resveratrol and the lowest permeability when combined with resveratrol, curcumin and piperine together. Conclusion: Combination of quercetin, resveratrol and curcumin may improve intestinal absorption of resveratrol and curcumin without affecting quercetin absorption. These data highlight the need for further research and suggest that developing combination therapies may improve intestinal absorption of these constituents. Our study also demonstrates that the apical-to-basal permeability across intact caco-2 monolayer model is a viable model to investigate absorption of natural compounds.
Non-Performing Loans in CESEE: Determinants and Impact on Macroeconomic Performance

The paper investigates the non-performing loans (NPLs) in Central, Eastern and South-Eastern Europe (CESEE) in the period of 1998–2011. The paper finds that the level of NPLs can be attributed to both macroeconomic conditions and banks’ specific factors, though the latter set of factors was found to have a relatively low explanatory power. The examination of the feedback effects broadly confirms the strong macro-financial linkages in the region. While NPLs were found to respond to macroeconomic conditions, such as GDP growth, unemployment, and inflation, the analysis also indicates that there are strong feedback effects from the banking system to the real economy, thus suggesting that the high NPLs that many CESEE countries currently face adversely affect the pace economic recovery.
Antecedents and patterns of e-Business adoption among small and medium enterprises (SMEs)

In many developing countries, small and medium enterprises (SMEs) serve as key drivers for economic growth. Despite SMEs' economic significance, their collective adoption of information and communication technology (ICT) for business activities, commonly known as e-Business, among them is generally limited. SMEs' diversity poses practical challenges to both government agencies and industry consultants looking to prescribe appropriate strategies in order to address the lack of eBusiness adoption issue for SMEs. This study attempts to establish patterns of e-Business adoption as a potential basis for future personalized strategies for SMEs. The study began by reviewing the literature for factors that might influence eBusiness adoption. A theoretical e-Business adoption model was developed based on the identified factors with which relevant hypotheses were then formulated. A questionnaire was then administered to SMEs with the objectives of measuring the influencing factors and the extent of their e-Business adoption. Data analysis was conducted in two phases. In the first phase, using SmartPLS, we conducted factor analysis to ensure reliabilities of measurement items and subsequently tested the theoretical e-Business adoption model. From the results, the factor of e-Business expertise emerged as a significant predictor or antecedent of e-Business adoption. In the second phase, the identified adoption factors were used as a basis for cluster analysis using TwoStep algorithm. In our analysis, we argue that SMEs may be better served if their adoption problems are addressed in accordance to respective adoption patterns instead of the traditional annual-turnover-based classifications. In addition, SMEs that score high on the adoption factors tend to use more extensive e-Business applications across their value chain.
Multiple-output LDO regulator applying with constant feedback factor

A Multiple-output LDO regulator can be a good choice in embedded systems in terms of no cross regulation, and efficiency. A small feedback factor in LDO topology incurs slow settling time, resulting in large ripples in the time-multiplexing strategy. A new proposed topology enhances the settling time, and hence the ripples by incorporating the constant feedback.
Highly functionalized EMC package materials for fingerprint sensors

The current trends of chip packaging technologies are moving towards providing the functional solutions for modules, where chips cannot fully perform their roles without the support of functionalized packaging materials. Functionalized EMC specialized for future capacitive fingerprint sensors and further wearable, Fintech, and IoT technologies requires following functions or properties: high dielectric constant (Dk: >21 or28), flexibility (Modulus at 25°C: < 10Mpa), flow-ability (spiral flow: > 60 inch) and uniformity of appearance (Defection rate by black stains: <0.02%). Here, we present the state of the art achievements on those functions and properties of functionalized EMC.
Cell Death and Survival TDP 1 and PARP 1 De fi ciency Are Cytotoxic to Rhabdomyosarcoma Cells

Rhabdomyosarcoma is the most common soft tissue sarcoma in children. Metastatic rhabdomyosarcoma in children has a 5-year event-free survival rate of <30%, and a recent clinical trial with irinotecan, a topoisomerase I inhibitor, failed to improve outcome. Therefore, it was surmised that failure of irinotecan may be the result of overexpression of the DNA repair enzyme tyrosyl-DNA phosphodiesterase (TDP1), which processes topoisomerase I-DNA complexes resulting from topoisomerase I inhibitor treatment. Using human tissue microarrays and gene expression arrays, a marked overexpression of TDP1 protein and mRNA in RMS tumors was observed. Critically, knockdown of TDP1 or inhibition of poly(ADP-ribose) polymerase-1 (PARP-1), an enzyme in the same complex as TDP1, sensitized rhabdomyosarcoma cell lines to analogues of irinotecan. Interestingly, BRCA1/2mutations or altered expression was not detectable in rhabdomyosarcoma cells; however, TDP1 knockdown and PARP-1 inhibition alone were cytotoxic to a subset of rhabdomyosarcoma cells, suggesting that they harbor genetic lesions in DNA repair components that have synthetic lethal interactions with loss of TDP1 or PARP1 function. Furthermore, culturing embryonal rhabdomyosarcoma cells in serum/nutrient–restrictedmedium increased cellular cytotoxicity uponPARP-1 inhibition and was intrinsically cytotoxic to alveolar, though not embryonal rhabdomyosarcoma cells. The results of these studies suggest a compensatory role for TDP1 in rhabdomyosarcoma after topoisomerase-I based therapy and further demonstrate that TDP1 knockdown, PARP-1 inhibition, and dietary restriction have therapeutic validity. Implications: Selective targeting of TDP1 and/or PARP-1 in rhabdomyosarcoma induces cytotoxicity and sensitizes to DNA damaging agents. Mol Cancer Res; 11(10); 1179–92. 2013 AACR.
Students’ Attitude and Satisfaction Living in Sustainable On-Campus Hostels

This research aims to investigate whether location, facilities and quality of on-campus hostels affect students’ attitude living in on-campus hostels and their satisfaction with hostel life. Next, relationship between students’ attitude and their satisfaction with hostel life are also examined. Data were collected from 230 students living in on-campus hostels in a public higher learning institution in the Federal Territory of Labuan, Malaysia. Empirical results via multiple regressions discovered that students’ satisfaction living in hostels is only affected by hostels quality, except for hostels location and hostels facilities. Students are very concerned that the floor be covered with tile, and the plumbing system be perfect with no water problems which affect their satisfaction living in hostels. Further investigation of the study recognized that students’ attitude is strongly affected by satisfaction followed by hostel facilities. This study provides strong evidence that could help the student housing administrators and the university hostel management and other accommodation services to better understand the customer satisfaction with the service delivery by identifying the significant factors in determining student satisfaction and improving the performance of university hostels towards meeting the satisfaction of students by providing highquality living environments. Direction for future research is also exemplified.
fms Like Tyrosine kinase3- Internal Tandem Duplication (FLT3-ITD) in Acute Myeloid Leukemia, Mutation Frequency and its Relation with Complete Remission, 2007- 2008

Introduction: About half of acute myeloid leukemia (AML) adult patients have no cytogenetic abnormalities as a main determinant of complete remission after treatment, so other markers are needed such as FLT3-ITD (Fms-like Tyrosine kinase3-internal tandem duplication) mutations in patients with normal karyotype. The objective of this study was assessing the frequency of FLT3-ITD mutations and its relation with complete remission in different FAB (French- American- British) and cytogenetic subgroups of AML patients who had been hospitalized at Tehran Imam Khomeini Hospital, hematology ward. Methods: The current study, was a cross sectional descriptive study which was performed during the years 2007-2008. Population frame were consecutive patients whose diseases were confirmed and who had been hospitalized in Tehran Imam Khomeini Hospital, hematology ward. Contemporary, flowcytometry, cytogenetic and chromosomal studies were performed for the cytogenetic subgroup assessment and to investigate the presence of FLT3-ITD mutation. Finally, complete remission achievement after induction chemotherapy were assessed. The obtained data was entered onto the information forms and analyzed by statistical tests. Results: Out of 40 patients who participated in this study, 18 (45%) were female and 22 (55%) were male. The median age of the patients with mutation was 33 years of age, and the ones without mutation were 39.5. M1, M2 and M4 FAB subgroups, with respectively 60, 37.5 and 35.7%, had the most occurrence of mutation. There was no significant relationship between mutation and the FAB subgroups (P=0.45). Favorable, intermediate and adverse cytogenetic risk groups had respectively 10, 37 and 66.7% mutations and 69.2% of the patients were in the normal karyotype group. Seventeen (42.5%) of the 40 patients achieved complete remission. 17.6% of them had mutations. There was no relationship between mutation and complete remission (P=0.085). Conclusion: There was no relationship between the presence of FLT3-ITD mutation and complete remission achievement following chemotherapy.
Methods to Increase the Robustness of Finite-Volume Flow Models in Thermodynamic Systems

This paper addresses the issues linked to simulation failures during integration in finite-volume flow models, especially those involving a two-phase state. This kind of model is particularly useful when modeling 1D heat exchangers or piping, e.g., in thermodynamic cycles involving a phase change. Issues, such as chattering or stiff systems, can lead to low simulation speed, instabilities and simulation failures. In the particular case of two-phase flow models, they are usually linked to a discontinuity in the density derivative between the liquid and two-phase zones. In this work, several methods to tackle numerical problems are developed, described, implemented and compared. In addition, methods available in the literature are also implemented and compared to the proposed approaches. Results suggest that the robustness of the models can be significantly increased with these different methods, at the price of a small increase of the error in the mass and energy balances.

Evaluation of variables in illicit drug use: does a controlled substance abuse screening tool identify illicit drug use?

STUDY DESIGN A retrospective, case-controlled study. OBJECTIVE To identify variables in patients with or without illicit drug use. BACKGROUND INFORMATION Studies documenting a high incidence of controlled substance abuse in chronic pain continue to increase. Over the years, multiple evaluation tools have been proposed. The need to identify predictors of aberrant drug related behavior and addiction in patients being treated with controlled substances for pain has been emphasized. METHODS A total of 150 patients were included in the study. One hundred consecutive urine tests without the presence of illicit drugs and 50 consecutive urine tests with the presence of illicit drugs of patients receiving controlled substances, were selected for evaluation of multiple variables of illicit drug use. They were divided into four groups with Group I with no controlled substance abuse and no illicit drug abuse with 70 patients; Group II with no controlled substance abuse, however, with positive illicit drug use with 33 patients; Group III with positive controlled abuse, however, with no illicit drug use with 30 patients; and Group IV with controlled substance abuse and illicit drug use with 17 patients. RESULTS Results of this study showed that of the eight variables described in a previous study in identifying controlled substance abuse, four variables were crucial. The four significant items identified in this evaluation were excessive opiate needs, deception or lying to obtain controlled substances, current or prior intentional doctor shopping, and current or prior use of illicit drugs and denial. These four variables were accurate in identifying controlled substance abuse. However, they failed to identify illicit drug use. CONCLUSION The presently available and validated screening tool for controlled substance abuse failed to identify illicit drug use in patients receiving controlled substances.
A low-power relaxation oscillator with improved thermal stability

In this paper, we present a novel on-chip relaxation oscillator (RO) with high temperature stability. By employing delay compensation circuit (DCC) in the delay loop, the transmission delay, which is highly sensitive to the temperature variation, is well-suppressed, leading to significantly elevated temperature stability of the RO's period. In addition, the proposed RO implementation features a low power consumption of 0. 11μW at 25° C, using 65nm 1.2V standard CMOS process. Moreover, according to our extensive simulation results, the variation of our proposed RO's output frequency is reduced to ±0.18% with the working temperature ranged from −55° C to 125° C, outperforming the other state of art RO designs.
Speech Recognition Experimental Results for Romanian Language

Automatic speech recognition in database-lacking languages like Romanian must imply new system designs or new methods in training state-of-the-art systems. We propose an innovative training strategy for Hidden Markov Models (HMM) based systems. It implies starting with isolated monophones training, going through isolated words training and finally reaching continuous speech training. Several experimental results show how the speech units used, the voice features employed, the HMM parameters utilized and the language restrictions imposed impact the recognition rates and implicitly the performance of the ASR systems.
