All-optical tunable filters built with discontinuity-assisted ring resonators

Numerically simulated performance is presented in a new type of bandstop and bandpass filters, built with discontinuity-assisted ring resonator (DARR)-loaded couplers. The operating characteristic of the bandpass filter is similar to that of a long grating with a centered cavity or a photonic crystal with a defect. The filters are tuned by varying the refractive index or the length of the waveguide forming the ring or the cavity. Selectivity and tuning range are controlled by the coupling coefficient of the couplers, by the order of resonance in the rings, and by the reflection coefficient of the discontinuities. A design procedure and the effect of loss are also presented.
Teaching soil science: The impact of laboratory and field components on the knowledge and attitude toward soil

The concept of attitude toward soil is emerging, with a slim choice of scales available to collect hard data. There is also a dearth of standard scales to acquire precise data on students’ knowledge of soil. Therefore, the objectives of the present study were: (1) to devise appropriate scales to quantify theoretical soil knowledge and attitude toward soil, and (2) to quantify the effect of laboratory studies and fieldwork on students’ theoretical soil knowledge and attitude toward soil. The study is based on data collected from undergraduate students of the introductory soil science course. Participating students were randomly divided into two groups. Teaching of the control group (n = 38) was classroom-based, while teaching of the intervention group (n = 43) was complemented with laboratory studies and fieldwork. Our test design included a pre-test and post-test. It appears that theoretical soil knowledge and students’ attitude toward soil can be improved using classroom-based education alone, without any need for laboratory or field components. However, future studies would be needed to develop questionnaires covering hands-on soil knowledge to better gauge the impact of lab work and field classes on student learning. The present study is an important step to elaborate reliable scales suitable for quantifying students’ knowledge and attitude toward the soil. It is impossible to test academic assumptions or create theoretical foundations for soil science education without a reliable device to weigh analytical concepts.
The Distribution Channels for Foreign-brand Apparel in China: Structure, Government’s Role, and Problems

The Chinese market is attractive to foreign-brand apparel manufacturers who have increasing access to the market as China’s economy has undergone a major transformation from a centrally planned to a market economy and has experienced continued growth. Because of China’s current economic transition and its status as a developing country, the channels for distributing foreign-brand apparel products to Chinese retailers presents special obstacles that foreigners may not anticipate. We detail the distribution channels for foreign-brand apparel in the Chinese market and identify problems in the channels. Because the Chinese government intervenes in the distribution channels in China, the role of the government in apparel distribution channels was also investigated. In-depth interviews were conducted with nine apparel retailers, three government officials, and one foreign-trade agent. Additionally, we surveyed 150 Beijing retailers who sell foreign-brand apparel. Contributions to the research on markets in less developed countries are addressed and implications for U.S. apparel manufacturers are presented.

Upper extremity joint stresses during walker- assisted ambulation in post-surgical patients Estresse articular no membro superior durante marcha assistida por andador em pacientes pós-cirúrgicos

Background: A walker is a common device prescribed for ambulatory assistance for individuals with balance difficulties or to reduce lower extremity demands following injury or surgery. The long-term use of a walker imposes significant demands on the patient's upper extremities that may lead to increased risk for development of secondary conditions such as wrist, elbow or shoulder pain. Objective: To describe the joint kinematics, forces and moments of the wrist, elbow and shoulder in a sample of twenty patients that were using a walker as a result of total joint surgery of the hips and knees. Methods: Three-dimensional upper extremity kinematics were recorded using a motion capture system synchronized with forces and torques transmitted through a walker instrumented with force transducers in the handles. Results: Compressive forces were found to be nearly 20% of the body weight at each of the upper extremity joints, both surgical and non-surgical sides, being the greatest force at the wrist and decreasing proximally. Compression forces were greater in the non-surgical side limb at the wrist and at the elbow. Conclusion: Our findings indicated that loads on upper extremity joints associated with the use of a walker for assisted ambulation are high and further studies are needed to address the cause-effect relationship between the actual joint loading and the development of secondary musculoskeletal upper extremity complaints in more frail patients.
Transient response of the modified variable-phase-shift automatic voltage regulator

In the variable-phase-shift automatic voltage regulator, the output is sampled at half-cycle intervals, and compared to a reference. The error is applied to a phase control circuit and filter, whose output is a sinusoid of constant amplitude, at mains frequency, but variable phase. This is amplified by a class B power amplifier, and added to the mains line voltage in such a sense as to correct it. Theoretical, simulation and experimental results are given to demonstrate the high accuracy (of the order of 0.2%), very fast response (between one half and one cycle) and low distortion of the device.
Detecting Segregation in Bituminous Pavements

Field and laboratory studies were conducted to determine the feasibility of detecting and quantifying segregation in hot-mix asphalt pavements. The study involved extensive testing at 19 field sites in Michigan. Areas of apparent segregation were classified as light, medium, and heavy. At the selected sampling areas, 1-min nuclear density measurements were made, cores were taken and incinerated, asphalt contents and air voids were determined, and gradation tests were performed. Statistical comparisons were made by using t-tests to characterize the differences between the measured nuclear density and percent passing various sieves. More than 80% of the nuclear density measurements supported the visual observations of a heavy degree of segregation when the significance of the differences (the p-value) between the areas compared was less than 10-3. Moreover, for areas with medium or heavy segregation, the probability that significant differences in nuclear density between segregated and nonsegregated areas with p-values less than 10-3 corresponded to significant differences (p-values less than 10-2) in aggregate gradation was . 88. On the basis of the results, a spreadsheet, mbitseg2, was developed to perform statistical tests with the nuclear density measurements obtained during the paving operation. After 6 months of trial testing, the program has been accepted and implemented by the Michigan Department of Transportation, the Michigan Asphalt Paving Association, and the asphalt industry. The program is available on a web page (http://www.egr.msu.edu/prce) in Excel (mbitseg2.xls) and QuattroPro (mbitseg2.wb3) formats.

A micro optical sensor based on twin-core fiber

A novel optical fiber sensor based on weak coupling twin-core fiber (TCF) is proposed and experimentally demonstrated. The sensing structure consists of two single mode fibers (SMF) and fabricated by program controlled tapering the spliced region between the first SMF and a segment of TCF. During this period the light power was gradually transferred from the SMF into the cladding mode near the waist zone, after the waist zone, the optical power was gradually concentrated from the cladding mode into the cores mode, which could affect the extinction ratio of the interference peaks in the transmission spectrum. In order to obtain better interference spectrum, we adjusted the fusion structure of the tail fiber and the TCF, and the cross sections of the optical fibers are dislocated to a certain extent, so that the interference process of the beam changes. In the process of adjusting the structure, we observed the spectral changes in the spectrometer at the same time until the best interference spectrum appeared, and then we completed the fusion. The interference between different modes can be affected by changes in the external environment, like refractive index (RI) and strain, which also dictates the wavelength shift of the transmission spectrum. In the experiment, we have studied the sensing response of the optical fiber sensor to the RI and strain, and the sensing sensitivity is 131.1nm/RIU and 1.26x10-3 dB/με respectively. All sensors fabricated in this paper show good linearity in terms of the spectral wavelength shift.
Recent advances in engineering montmorillonite into catalysts and related catalysis

ABSTRACT Montmorillonite, a ubiquitous clay mineral, has been engineered into a variety of porous and nanostructured catalysts, owing to its peculiar layered structure with characteristic surface and intercalation chemistry. Such a class of catalysts have continuously received considerable attention in both science and industry. This review examines recent advance in engineering montmorillonite into metal ion-exchanged montmorillonite catalysts, acid-activated montmorillonite catalysts, organo-montmorillonite catalysts, pillared interlayered montmorillonite catalysts and montmorillonite-supported catalysts. The former two types of montmorillonite-based catalysts have been used in the catalytic cracking, dehydration, hydrolysis, esterification, polymerization, alkylation, and Fischer-Tropic synthesis. The introduction of oxide pillars in the interlayer space of montmorillonite and the immobilization of metal oxides or zero-valent metals on the surface of montmorillonite allow montmorillonite to be used in the catalytic oxidation, reduction, isomerization and coupling reactions. Currently, the role of montmorillonite in acid catalysis, redox catalysis, and free radical catalysis have been partly revealed. The effect of the structures and the active sites of modified montmorillonite on its catalytic performance need to be investigated in more detail. Future work is suggested to focus on solving engineering problems and exploring novel catalytic applications of montmorillonite, in particular exfoliated montmorillonite nanolayers.

Kinematic Methods for Quantifying Loss of Balance While Negotiating a Curved Path on a Slippery Surface

Ten healthy industrial workers were recruited to perform a gait test for this study. The workers were required to negotiate straight and turning paths on dry and very slippery surfaces. Seven variables that quantify loss of balance during single stance were used to assess the potential of loss of balance when negotiating the different paths on slippery surfaces. These variables included measure of the distance of the whole body center of gravity (COG) deviated from the supporting base, slide distance, slide direction, and turning radius. Using these variables, it was possible to biomechanically conclude that negotiating a curved path on a slippery surface was the most difficult task, with the highest potential of loss of balance and fall. The direction most subjects' feet slid was 52 to 60° in the lateral direction. This study provides range of COF values in the lateral direction between the shoe-floor interface for preventing slip when negotiating a curved path.

Global potential distribution of three underappreciated arboviruses vectors (Aedes japonicus, Ae. vexans, and Ae. vittatus) under current and future climate conditions.

Arboviruses (arthropod-borne viruses) are expanding their geographic range, posing significant health threats to millions of people worldwide. This expansion is associated with efficient and suitable vector availability. Apart from the well-known Aedes aegypti and Ae. albopictus, other Aedes species may potentially promote the geographic spread of arboviruses because these viruses have similar vector requirements. Aedes japonicus, Ae. vexans, and Ae. vittatus are a growing concern, given their potential and known vector competence for several arboviruses, including dengue, chikungunya, and zika viruses. In the present study, we developed detailed maps of their global potential distributions under both current and future (2050) climate conditions, using an ecological niche modeling approach (Maxent). Under present-day conditions, Ae. japonicus and Ae. vexans have suitable areas in the northeastern United States, across Europe, and in southeastern China, whereas the tropical regions of South America, Africa, and Asia are more suitable for Ae. vittatus. Future scenarios anticipated range changes for the three species, with each expected to expand into new areas that are currently not suitable. By 2050, Ae. japonicus will have a broader potential distribution across much of Europe, the United States, western Russia, and central Asia. Aedes vexans may be able to expand its range, especially in Libya, Egypt, and southern Australia. For Ae. vittatus, future projections indicated areas at risk in sub-Saharan Africa and the Middle East. As such, these species deserve as much attention as Ae. aegypti and Ae. albopictus when processing arboviruses risk assessments and our findings may help to better understand the potential distribution of each species.

Novel fast voltage stability index (FVSI) for voltage stability analysis in power transmission system

Since a couple of decades ago, voltage stability assessment has received increasing attention due to the complexity of power systems. With the increase in power demand and limited power sources has caused the system to operate at its maximum capacity. Therefore, a study that is able to determine the maximum capacity limit before voltage collapse must be carried out so that necessary precaution can be taken to avoid system capacity violation. This paper presents a novel fast voltage stability index (FVSI) simplified from a pre-developed voltage stability index referred to a line initiated from the voltage quadratic equation at the sending end of a representation of a 2-bus system. The line index in the interconnected system in which the value that is closed to 1.00 indicates that the line has reached its instability limit which could cause sudden voltage drop to the corresponding bus caused by the reactive load variation. The formulated index was tested on the IEEE reliability test system in order to verify the performance of the proposed indicator. Results showed that the proposed technique is indicative in predicting the occurrence of system collapse and hence necessary action can be taken to avoid such incident.
