A feasibility study of gender recognition with a near–infrared ray scanning spectrophotometer
Authors: Nishino Satoshi , Ohshima Kenji 
Published: August 2011

AbstractMale and female recognition is necessary to strengthen security and when various statistics on visitors are taken in commercial facilities and so on. The conventional method of male and female recognition currently makes use of the person's appearance, the dress, and in some cases, manner of walking, foot pressure, and hair type. But these characteristics can be intentionally changed by human intervention or design. The proposed method obtains differences in male and female characteristics from the absorbance characteristics of the fat distribution in a person's cheek, using a near‐infrared ray scanning spectrophotometer. This is a method of male and female recognition based on a new concept. Consequently, it can be used to distinguish males and females even in disguise, because it involves biometric authentication. © 2011 Wiley Periodicals, Inc.

A few comments on visual systems of a ship handling simulator for sea pilot training: Training for entering a port
Authors: Murai Koji , Okazaki Tadatsugi , Hayashi Yuji 
Published: August 2011

AbstractWe are using a ship handling simulator for sea pilots' training. However, regarding the visual image around the pilot's own ship in the case of entering a port, ordinary ship handling simulators do not have such a visual image (screen). We undertook to clarify the effect of a visual system around the pilot's own ship for entering a port. Training for entering a port is an important training factor for a sea pilot. This paper describes the characteristics of the captain's visual observation area and the mental workload for ship handling when entering a port. The visual observation area is determined from eye movement and the mental workload is determined from heart rate variability (R‐R interval) and nasal temperature. The results show that the visual system around the pilot's own ship promotes safe ship handling when entering a port, based on eye movement. © 2011 Wiley Periodicals, Inc.

A Stereoselective Synthesis of Sugar‐Derived Chiral β‐Lactams
Authors: Khangarot Rama Kanwar , Kaliappan Krishna P. 
Published: August 2011

AbstractThe importance of the β‐lactam substructure is exemplified by the several classes of β‐lactam antibiotics. Among the synthetic routes available to obtain this interesting scaffold, the Kinugasa reaction is a convergent strategy. In this article, the synthesis of a variety of chiral β‐lactams by the Kinugasa reaction between terminal alkynes and nitrones is described. These sugar‐derived β‐lactams were synthesized by the reaction between cyclic nitrones derived from different sugars, tartrate ester, and alkynes obtained from different sugars. The reaction gave moderate to good yields of β‐lactams with high diastereoselectivity, mainly producing a single product. The stereochemical preferences observed in these reactions are also explained.
Determination of inert COD from different dyestuff used textile industries
Authors: Ozkan Oktay , Oguz Merve , Varinli Fatma 
Published: August 2011

AbstractThis study was performed to compare the chemical oxygen demand (COD) fractions of textile wastewaters containing reactive and indigo dyestuffs. In the textile wastewater containing reactive dyestuff, inert soluble COD (SI) concentration was found as 94 mg/L and residual soluble microbial products concentration (SP1) was 53 mg/L. This total (SI + SP1) was about 21 ratios of total initial COD (CTO). On the other hand, in the textile wastewater containing indigo dyestuff, SI and SP2 were observed as 160 mg/L and 69 mg/L, respectively, which is about 21 ratios of CTO. The investigation of different dyestuff used wastewaters indicated that indigo dyestuff used textile industry wastewater had higher inert COD content due to the complex structure of the indigo dyestuff. However, the biodegradability characteristics show similarity for both wastewaters. The results also indicated that biological treatment alone cannot be adequate to provide the discharge limits for both wastewaters. © 2011 American Institute of Chemical Engineers Environ Prog, 2011
Rateless codes aided coherent M‐ary PSK systems in the presence of receiver imperfections and Rician fading
Authors: Yang Jing , An Jianping , Li Xiangming , Yuan Lei 
Published: August 2011

ABSTRACTIn this paper, we study the bit error rate (BER) and the symbol error probability (SEP) performance for a rateless coded M‐ary phase‐shift keying (MPSK) system in a situation where stochastic phase error, quadrature error and in‐phase–quadrature (I–Q) gain mismatch take place all concurrently over a Rician fading channel. Similar scenario has been considered before by Djordjevic et al. for quasi‐cyclic low‐density parity‐check (QC‐LDPC) codes, but the effect of I–Q gain mismatch is not correctly modeled, because the Gaussian noise components in I and Q paths are assumed to have the same variance. By taking two different Gaussian noise variances into consideration, precise expressions are derived for the SEP of a coherent MPSK system under the aforementioned condition (with the stochastic phase error depicted by Tikhonov distribution), thus providing a baseline to evaluate the merits of the proposed rateless coded system and that of QC‐LDPC codes. The validity of the rateless coded system is substantiated by simulation results. It is observed that rateless codes outperform QC‐LDPC codes even the I–Q gain mismatch is modeled in the same way as Djordjevic's work when the target BER is lower than 10−2.

On cost‐sharing mechanisms in cognitive radio networks
Authors: Sodagari Shabnam , Bilén Sven G. 
Published: August 2011

ABSTRACTWe present a framework and pertinent formulations for a coalition of secondary cognitive radios that are willing to lease inactive spectrum band from a primary system through auctioning and to share the received bandwidth and the associated cost among themselves using multiple access techniques. We cast this scenario to submodular class of games and show how a link can be established between the truthful auctioning mechanism and the cost‐sharing algorithm. Simulation results verify that the deployed cost‐sharing technique leads to encouraging the secondary cognitive radios to truthfully announce their bids. Copyright © 2011 John Wiley & Sons, Ltd.

AbstractCyclotriveratrylene (CTV) and related C3‐symmetric hosts are host molecules with a pyramidal shape and electron‐rich molecular cavities. Appropriately functionalized CTV derivatives can self‐assemble into nano‐ scale cage‐like assemblies through metal–ligand interactions or hydrogen bonding. Examples of such assemblies include metallo‐cryptophanes and hydrogen bonded capsules, M4L4 and M4L6 tetrahedra, M6L8 stella octangulas, along with cages with unusual topological features.
Managing terraced lowland and medium sloping land for sustainable agriculture: A study from the eastern ghat region of India
Authors: Panda R. K. , Arora C. P. , Gore K. P. , Jakhar P. , Dash B. K. 
Published: August 2011

ABSTRACTJudicious management of the terraced lowlands and adjacent medium‐sloping lands of the Eastern Ghat Region in India was addressed through a case study, in order to develop a sustainable agriculture package as a resource for poor tribal farmers. Quantification of available water resources during the period 2004–2007 revealed that average base flow and surface flow (as percentage of total rainfall) at a level of 37.2 and 34.7% respectively, could be made available in the study area, and would otherwise go out of the system without proper utilization. Economic resource conservation options for farmers, such as the management of paddy field riser bunds through construction of semi‐mechanical runoff disposal devices supplemented with a Eulaliopsis binata vegetative barrier, helped in reducing runoff and soil loss by 10.6% and 1.45 t ha‐1, respectively. Through paired t‐tests at a 5% probability level, significant differences were observed in the reduction of the sediment yield, when comparing the proposed techniques with the farmers’ practices. Introduction of a promising HYV paddy cultivar (Oryza sativa L. or Lalat) fortified with the application of Gliricidia sepium leaves (grown on the periphery of the terraced lowlands) resulted in a paddy yield of 4.2 t ha‐1 as against 1.7 t ha‐1 obtained through the local paddy cultivar. Further, based on the availability of runoff water through a perennial stream, it was found that provision for a diversion irrigation channel constructed to harvest water would be a promising option for irrigating the adjacent medium‐sloping land for remunerative vegetable cultivation. Overall, the developed integrated package resulted in a cost–benefit ratio of 2.6:1 with a net present value of Rs. 116 000.00 (US$2900) at a 15% discount rate, increasing the scope for replicating this technology in other parts of the Eastern Ghat region.

Published: August 2011

AbstractBACKGROUND:New resident work‐hour restrictions are expected to result in further increases in the number of handoffs between inpatient care providers, a known risk factor for poor outcomes. Strategies for improving the accuracy and efficiency of provider sign‐outs are needed.OBJECTIVE:To develop and test a judgment‐based scale for conveying the risk of clinical deterioration.DESIGN:Prospective observational study.SETTING:University teaching hospital.SUBJECTS:Internal medicine clinicians and patients.MEASUREMENTS:The Patient Acuity Rating (PAR), a 7‐point Likert score representing the likelihood of a patient experiencing a cardiac arrest or intensive care unit (ICU) transfer within the next 24 hours, was obtained from physicians and midlevel practitioners at the time of sign‐out. Cross‐covering physicians were blinded to the results, which were subsequently correlated with outcomes.RESULTS:Forty eligible clinicians consented to participate, providing 6034 individual scores on 3419 patient‐days. Seventy‐four patient‐days resulted in cardiac arrest or ICU transfer within 24 hours. The average PAR was 3 ± 1 and yielded an area under the receiver operator characteristics curve (AUROC) of 0.82. Provider‐specific AUROC values ranged from 0.69 for residents to 0.85 for attendings (P = 0.01). Interns and midlevels did not differ significantly from the other groups. A PAR of 4 or higher corresponded to a sensitivity of 82% and a specificity of 68% for predicting cardiac arrest or ICU transfer in the next 24 hours.CONCLUSIONS:Clinical judgment regarding patient stability can be reliably quantified in a simple score with the potential for efficiently conveying complex assessments of at‐risk patients during handoffs between healthcare members.

WE ARE NOT POOR! DOMINANT AND SUBALTERN DISCOURSES OF PASTORALIST DEVELOPMENT IN THE HORN OF AFRICA
Authors: Scott‐Villiers Patta 
Published: August 2011

AbstractThis paper explores a moment in a policy meeting in Nairobi in 2009, at which pastoralist customary leaders criticised development agencies' framing of their situation as poverty stricken and in crisis. Analysing the communicative moment, providing context from field research and drawing on ethnography and philosophy, I explore what we can learn about the conduct of a long battle between dominant and subaltern discourses of pastoralist development. I conclude that this is just one incident in a long war between development's universalising discourse and those of people in the rest of the world who see things differently.

A CHALLENGE FOR RESEARCH IN DEVELOPMENT STUDIES ON VALUES, ETHICS AND MORALS
Authors: Fischer Andrew M. , Kothari Uma 
Published: August 2011

AbstractThe articles in this special issue represent a selective output from the 2010 annual conference of the Development Studies Association on the theme of ‘Development Paths: Values, Ethics and Morality’. Following a brief introduction to the articles, we pose several future research challenges in the field of Development Studies with respect to this theme. One involves moving beyond orientalism and reverse‐orientalism in the question of values. The second relates to how values and ethics are institutionalised within rapid developmental transformations. The third addresses how the conditions of poverty and inequality are structurally produced through systems and ideologies of valuation. Finally, the current context of high levels of inequalities within and between societies begs for introspection in the field of Development Studies about how values and ethics are related to these inequalities. Ultimately, if we are to maintain our legitimacy as a field of studies that emerged in the era of decolonisation, we need to address the persistence of old and the emergence of new forms of severe exploitation and subordination in a world of so much affluence and at a time when human rights have come to be accepted as near‐universal principles of governance.

Authors: Fujimoto Sakae , Morikawa Shigehiro , Inubushi Toshiro 
Published: August 2011

AbstractPurpose:To apply magnetic resonance (MR) imaging to differential diagnosis of cardiogenic pulmonary edema (CPE) and noncardiogenic pulmonary edema (NCPE).Materials and Methods:In the CPE group, MR measurements were performed on 5 rats just before and 3 h after administration of 21 ± 2% body weight of normal saline. In the NCPE group, measurements were similarly performed on 5 animals just before and 48 h after 0.75 mg/body of lipopolysaccharide intratracheal administration. Animals were killed for bronchoalveolar lavage fluid (BALF) or pathological analysis after MR measurements.Results:The relation between signal intensity and the T2* value of MR imaging was different in the two groups. The T2* in the NCPE group was significantly longer than that in the CPE group at the same signal intensity level. The lactate levels measured by in vivo MR spectroscopy did not show a difference between the CPE and NCPE groups, although the lactate BALF levels of the two groups were significantly different.Conclusion:The relation between signal intensity and T2* value was useful for the differentiation between these two pulmonary diseases. The measurable lactate level in pulmonary lesions suggests the applicability of MR spectroscopy to pulmonary disease. J. Magn. Reson. Imaging 2011;. © 2011 Wiley Periodicals, Inc.

AbstractThe meniscus plays an important role in controlling the biomechanics of the knee. However, the mechanical stress‐related response in meniscus cells remains unclear. We investigated mechanical stretch‐regulated gene expression in human meniscus cells. Human inner and outer meniscus cells were prepared from the inner and outer halves of the lateral meniscus. The gene expressions of Sry‐type HMG box (SOX) 9 and α1(II) collagen (COL2A1) were assessed by real‐time PCR analyses after cyclic tensile strain (CTS) treatment (0.5 Hz, 5% stretch). The localization and phosphorylation of SOX9 were evaluated by immunohistochemical and Western blot (WB) analyses. Chromatin immunoprecipitation (IP) analysis was performed to assess the stretch‐related protein–DNA complex formation between SOX9 and the COL2A1 enhancer on chromatin. Type II collagen deposition and SOX9 production were detected only in inner menisci. CTS treatments increased expression of the COL2A1 and SOX9 genes in inner meniscus cells, but not in outer meniscus cells. In addition, CTS treatments stimulated nuclear translocalization and phosphorylation of SOX9 in inner meniscus cells. Chromatin IP analyses revealed that CTS increased the association between SOX9 and its DNA‐binding site, included in the COL2A1 enhancer, on chromatin. Our results indicate that inner and outer meniscus cells have different properties in mechanical stretch‐induced COL2A1 expression. In inner meniscus cells, mechanical stretch may have an essential role in the epigenetic regulation of COL2A1 expression. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Augmentation of peri‐implant bone improves implant stability: Quantification using simulated bone loss
Authors: Wirth Andreas J. , Müller Ralph , van Lenthe G. Harry 
Published: August 2011

AbstractLow bone quality, such as induced by osteoporosis, is considered a main factor leading to failure of fracture fixations. Peri‐implant bone augmentation has been proposed as a means of reducing failure rates in osteoporotic bone by improving implant stability. The beneficial effects of pharmacological augmentation of bone in the immediate vicinity of the implant have been demonstrated. Yet, a quantitative understanding of the role of peri‐implant bone in implant stability is lacking. Therefore, the aim of our study was to quantify the effects of bone loss and peri‐implant bone augmentation on implant stability using image‐based finite element analyses. Using a validated model, we simulated how osteoporotic bone loss would affect implant stability in human humeral heads. We also quantified how augmentation of peri‐implant bone can enhance implant stability. Our simulations revealed that a 30% reduction in bone mass led to a 50% decrease in implant stability. We also found that peri‐implant bone augmentation increased implant stability and that the efficiency of bone augmentation decreased with increasing peri‐implant distance. These findings highlight the strong effect that bone loss has on implant fixation and the potential of peri‐implant bone augmentation for improving implant anchorage in low quality bone. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Published: August 2011

AbstractTo understand the potential mechanism for hand and wrist complaints in pipette users, whose motion is characterized by repetitive thumb motion in certain wrist positions, the peak (PGR) and mean (MGR) gliding resistance of the flexor pollicis longus (FPL) tendon were measured in nine human cadaver wrists. The PGR with the wrist in 30° ulnar deviation and in the neutral position were significantly lower than the PGR with the wrist in 60° flexion. The MGR with the wrist in 30° ulnar deviation was significantly lower than the MGR with the wrist in 60° flexion, 60° extension, or 20° radial deviation with 40° extension. Based on these data, we believe that a manual pipette designed to be used in neutral to ulnar deviated wrist position could have ergonomic advantages. © 2011 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Published: August 2011

AbstractUVB radiation is the major carcinogen responsible for skin carcinogenesis, thus elucidation of the molecular pathways altered in skin in response to UVB would reveal novel targets for therapeutic intervention. It is well established that UVB leads to upregulation of cyclooxygenase 2 (COX‐2) in the skin which contributes to skin carcinogenesis. Overexpression of COX‐2 has been shown to promote colon cancer cell growth through β‐catenin signaling, however, little is known about the connection between UVB, COX‐2, and β‐catenin in the skin. In the present study, we have identified a novel pathway in which UVB induces β‐catenin signaling in keratinocytes, which is modulated by COX‐2 expression. Exposure of the mouse 308 keratinocyte cell line (308 cells) and primary normal human epidermal keratinocytes (NHEKs) to UVB resulted in increased protein levels of both N‐terminally unphosphorylated and total β‐catenin. In addition, we found that UVB‐enhanced β‐catenin‐dependent TOPflash reporter activity and expression of a downstream β‐catenin target gene. We demonstrated that UVB‐induced β‐catenin signaling is modulated by COX‐2, as treatment of keratinocytes with the specific COX‐2 inhibitor NS398 blocked UVB induction of β‐catenin. Additionally, β‐catenin target gene expression was reduced in UVB‐treated COX‐2 knockout (KO) MEFs compared to wild‐type (WT) MEFs. Furthermore, epidermis from UVB‐exposed SKH‐1 mice exhibited increased N‐terminally unphosphorylated and total β‐catenin protein levels and increased staining for total β‐catenin, and both responses were reduced in COX‐2 heterozygous mice. Taken together, these results suggest a novel pathway in which UVB induces β‐catenin signaling in keratinocytes which is enhanced by COX‐2 expression. © 2011 Wiley Periodicals, Inc.
