A MAC protocol based on adaptive bearnforming for ad hoc networks (2004)

This paper presents a novel slotted MAC (medium access control) protocol for nodes equipped with adaptive antenna array in ad hoc network. The protocol relies on the ability of antenna to uses DOA (direction-of-arrival) information to beamform by placing nulls in the direction of interferers thus maximize SINR (signal to interference and noise ratio) at the receiver. We studied the performance of the protocol using joint simulation in OPNET and Matlab. We studied the impact of variable number of antenna elements, DOA algorithm, and nulling. The performance of our new protocol is compared against one of the recent directional MAC protocols [R.R.N.H.V. Romit Roy Choudhury, Xue Yang, 2002]. We observe that despite the simplicity of our protocol it achieves high throughput.
Nasopharyngeal angiofibroma: A twenty year study. (1978)

A control rate of approximately 80% has been obtained in 45 cases of juvenile nasopharyngeal angiofibroma treated by a single moderate dose of radiotherapy at the Princess Margaret Hospital, Toronto. The remaining patients ultimately achieved control generally after further irradiation. Immediate side-effects of the treatment have been minimal, and no late complications have been observed. In 2-20 years' follow-up, no irradiation-induced tumors have been found. Superiority of irradiation in these cases over surgery is emphasized, as well as the importance of using sophisticated techniques to limit the volume of tissues irradiated and protect vulnerable radiosenstitive structures. Because tumor regression can be expected to continue for many months after treatment has been completed, a policy of observation following radiotherapy is recommended.
Thin Silicon Film p-i-n Photodiodes with Internal Reflection (1978)

A new kind of silicon p-i-n photodiode is presented which combines broad wavelength response at high quantum efficiencies (450 to 900 nm ~85 percent) and extremely fast response time (typically below 100 ps). The diodes use internal light reflection. Theoretical expressions for different types of gratings are presented. The fabrication steps for both the different kinds of gratings and the diode itself are given. Experimental data of the time and wavelength response prove this expected excellent behavior.
A Comparison of Sampling Techniques for Web Graph Characterization (2006)

We present a detailed statistical analysis of the characteristics of partial Web graphs obtained by sub-sampling a large collection of Web pages. We show that in general the macroscopic properties of the Web are better represented by a shallow exploration of a large number of sites than by a deep exploration of a limited set of sites. We also describe and quantify the bias induced by the different sampling strategies, and show that it can be significant even if the sample covers a large fraction of the collection.
Newly Developed High Q FBAR with Mesa-Shaped Membrane (2006)

In this paper, the authors present the newly developed high Q film bulk acoustic resonator (FBAR) which has the piezoelectric AlN film sandwiched between two electrode films and mesa-shaped membrane structure by utilizing poly-Si and XeF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> as a sacrificial layer and dry release gas, respectively. By controlling the etching profile of bottom electrode and sacrificial layer, the poor formation of AlN in the edge region of mesa-shaped membrane could be eliminated. In addition, by reducing the parasitic overlap which both of the electrodes and the piezoelectric layer resides directly on the substrate, the authors improve the characteristics of resonator and filter. When we compare with the typical surface micromachined FBAR, such as resonator having its own Bragg reflector or cavity, we could greatly reduce the needs for tight control of chemical mechanical polishing (CMP) of the layer underneath the resonator. The measured Q value and effective electromechanical coupling coefficient of the resonator with the area of 120times120 mum <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> were 1450 and 6.43%. The peak insertion loss (IL) and bandwidth of filter were 0.60 dB and 70 MHz, respectively
The Effect of Heat Treatment on the Bulk Lifetime of Excess Charge Carriers in Silicon † (1957)

In a recent paper G. Bemski (1956) described the decrease of the bulk lifetime of excess charge carriers in silicon found when silicon samples were quenched from temperatures lower than 550°c to room temperature, and the complete or partial restoration of the original lifetime when the samples were annealed in the same range of temperatures. During recent months we have studied the effects of heat treatment of silicon in the range between room temperature and 1250°c. We found that bulk lifetime both in p- and n-type crystals made by the floating zone method and of n-type crystals made by the Czochralski technique might be increased by annealing at temperatures between about 300°c and 700°c. Annealing at temperatures higher than about 700°C decreased lifetime both in p- and n-type crystals. In ail cases the samples were relatively slowly cooled. The mechanism of these changes in lifetime is not well understood.

Documents at Hand (2005)

In this paper the results of a two-year ethnographic study of the personal document management of 28 information workers is described. Both the paper and digital domain were taken into account during the study. The results reaffirmed that document management is strongly related to task management. Digital tools do not adequately support two important user needs related to task management, namely that documents should be embedded within meaningful (task-related) context information, and that they should be easily accessible for regrouping as the task goes on. In contrast, paper supports these needs very well. Following a discussion of personal document management using paper, email, and digital file folder structures, six implications are outlined for the design of digital document management systems that combine the advantages of both domains.
The Carbohydrate Counting in Adolescents With Type 1 Diabetes (CCAT)Study (2009)

This article reports pilot study results evaluating the accuracy of carbohydrate counting among adolescents with type 1 diabetes. This cross-sectional observational study included 48 adolescents ages 12–18 years (mean 15.2 ± 1.8 years) with type 1 diabetes of &gt; 1 year in duration (mean A1C 8.0 ± 1.0%) who used insulin:carbohydrate (I:C)ratios for at least one meal per day. The adolescents were asked to assess the amount of carbohydrate in 32 foods commonly consumed by youths. Foods were presented either as food models or as actual food, with some items presented as standard serving sizes and some self-served by study participants. T-tests were used to assess the significance of over- or underestimation of carbohydrate content. For each meal, accuracy was categorized as accurate (within 10 grams), overestimated (by &gt; 10 grams),or underestimated (by &gt; 10 grams) based on the commonly used I:C ratio of 1 unit of insulin per 10 grams of carbohydrate. Only 23% of adolescents estimated daily carbohydrate within 10 grams of the true amount despite selection of common meals. For dinner meals, individuals with accurate estimation of carbohydrate grams had the lowest A1C values (7.69± 0.82%, P = 0.04). The pilot study provides preliminary evidence that adolescents with type 1 diabetes do not accurately count carbohydrates. Further data are needed on carbohydrate counting accuracy and other factors that affect glycemic control.

Lupus nephritis: an historical perspective 1968-1998. (2000)

Lupus is now regarded as a syndrome which results from several related auto-immune processes, although the exact mechanisms of how the disease arises in susceptible individuals remain obscure. When the San Carlo meetings began in 1968, much less was known about the pathogenesis of autoimmunity, but the presence of autoantibodies and autoreactive cells had been worked out, the patterns of the disease and its clinical and histological expression in the kidney were well described. At that time, however, the prognosis for severe forms of lupus nephritis was miserable, although patients either milder disease might survive for decades. During the late 1950s and 1960s relatively effective palliative treatment first with corticosteroids and then cytotoxic drugs were introduced, which disappointingly remain the principal treatments 40 years later, although they have improved the prognosis of severe lupus nephritis to equal that of milder forms. However, better understanding of the immune reaction promises newer forms of more precisely-targeted treatment for the near future.
Causative Species and Serotypes of Shigellosis in Mainland China: Systematic Review and Meta-Analysis (2012)

This study provides an updated review of the causative agents of shigellosis in mainland China and focuses on the importance of strengthening prevention and research efforts on S. sonnei and the newly emerged S. flexneri serotype 4c.
Periodicity and Parity Theorems for a Statistic on r-Mino Arrangements (2006)

We study polynomial generalizations of the r-Fibonacci and r-Lucas sequences which arise in connection with a certain statistic on linear and circular r-mino arrangements, respectively. By considering special values of these polynomials, we derive periodicity and parity theorems for this statistic on the respective structures. 1
Bimorph adaptive mirror (1992)

A cooled copper adaptive mirror based on a double bimorph structure is proposed for the compensation of large-scale optical aberrations, including those that occur in power systems with an output up to 15 kW. The construction of the adaptive mirror is described and the results are given of calculations and of experimental studies of thermal deformations of the reflecting surface, of the response functions of the control electrodes, and of the frequency properties of the mirror. Estimates are obtained of the effectiveness of compensation of low-order optical aberrations.
Characterization of Polypeptide Antibiotics of the Polymyxin Series by Liquid Chromatography Electrospray Ionization Ion Trap Tandem Mass Spectrometry (2002)

A selective reversed phase liquid chromatography/mass spectrometry (LC/MSn) method is described for the identification of related compounds in commercial polymyxin B samples. Mass spectral data for these polypeptide antibiotics were acquired on a LCQ ion trap mass spectrometer equipped with an electrospray ionization probe operated in the positive ion mode. The LCQ ion trap is ideally suited for the identification of the related substances because it provides on-line LC/MSn capability. The main advantage of this hyphenated LC/MSn technique is the characterization of novel related substances without time-consuming isolation and purifications procedures. Using this method six novel related substances were partially identified in a polymyxin B bulk sample.
A Novel Absorption Regeneration-Thermodynamic Heat Engine Cycle (1978)

This paper introduces and provides a first order thermal cycle analysis of a new power plant design, the absorption-regeneration power cycle. Preliminary analysis indicates that this new cycle may have potential for increased operating efficiencies compared to the modified Rankine cycle presently in use for most stationary electrical power production. Graphs are presented to illustrate calculated efficiencies as well as some important design parameters of the cycle. Research work on extending presently available thermo-chemical data required to improve the model analysis is suggested.
Tim23, a Protein Import Component of the Mitochondrial Inner Membrane, Is Required for Normal Activity of the Multiple Conductance Channel, MCC (1997)

We previously showed that the conductance of a mitochondrial inner membrane channel, called MCC, was specifically blocked by peptides corresponding to mitochondrial import signals. To determine if MCC plays a role in protein import, we examined the relationship between MCC and Tim23p, a component of the protein import complex of the mitochondrial inner membrane. We find that antibodies against Tim23p, previously shown to inhibit mitochondrial protein import, inhibit MCC activity. We also find that MCC activity is altered in mitochondria isolated from yeast carrying the tim23-1 mutation. In contrast to wild-type MCC, we find that the conductance of MCC from the tim23-1 mutant is not significantly blocked by mitochondrial presequence peptides. Tim23 antibodies and the tim23-1 mutation do not, however, alter the activity of PSC, a presequence-peptide sensitive channel in the mitochondrial outer membrane. Our results show that Tim23p is required for normal MCC activity and raise the possibility that precursors are translocated across the inner membrane through the pore of MCC.
The relationship between Phalaris arundinacea and Glyceria grandis and their epiphyte communities in the Maple River. (2002)

The relationship between epiphytes and their aquatic hosts has scarcely been studied for freshwater ecosystems. The epiphytes gain substrate on which to live from the plants but how do they affect the plants? Understanding this relationship is of importance to understand the diversity of macrophytes in streams. If the epiphytes benefit their macrophytic hosts, then significantly decrease growth should be observed for the plants scrubbed of their epiphytes when compared to the controls. Here the effect was examined in two sites similar in physical characteristics in the Maple River, Northern Lower Michigan. Phalaris arundinacea and Glyceria gradis were the organisms chosen for study due to their abundance and accessibility. Epiphytes were scrubbed from the treated group three times a week for two weeks, during which time the heights and leave numbers were recorded. In the end a t-test was preformed to look for a significant difference in growth between the control groups and the treated groups. No significance was found for the over all change in growth and leaf number of the plants leaving the hypothesis neither supported nor refuted. This was probably due to the brevity of the study and because it was preformed towards the end of the growing season. It is suggested that future studies run longer trials during spring, the height of the growing season.
Regioselective Liquid-Phase Toluene Nitration with Modified Clays as Catalysts (1988)

Abstract Catalytic mononitration of toluene (yields of 50–81%; turnover at least 850) occurs in the presence of modified clays with useful regioselectivities, such as (o:m:p) = 31:2:67. The nitrating species is extracted from concentrated nitric acid by carbon tetrachloride-acetic anhydride mixture.
A Self-Adaptive Model-Based Wi-Fi Indoor Localization Method (2016)

This paper presents a novel method for indoor localization, developed with the main aim of making it useful for real-world deployments. Many indoor localization methods exist, yet they have several disadvantages in real-world deployments-some are static, which is not suitable for long-term usage; some require costly human recalibration procedures; and others require special hardware such as Wi-Fi anchors and transponders. Our method is self-calibrating and self-adaptive thus maintenance free and based on Wi-Fi only. We have employed two well-known propagation models-free space path loss and ITU models-which we have extended with additional parameters for better propagation simulation. Our self-calibrating procedure utilizes one propagation model to infer parameters of the space and the other to simulate the propagation of the signal without requiring any additional hardware beside Wi-Fi access points, which is suitable for real-world usage. Our method is also one of the few model-based Wi-Fi only self-adaptive approaches that do not require the mobile terminal to be in the access-point mode. The only input requirements of the method are Wi-Fi access point positions, and positions and properties of the walls. Our method has been evaluated in single- and multi-room environments, with measured mean error of 2-3 and 3-4 m, respectively, which is similar to existing methods. The evaluation has proven that usable localization accuracy can be achieved in real-world environments solely by the proposed Wi-Fi method that relies on simple hardware and software requirements.
The gene encoding glutathione‐dependent formaldehyde dehydrogenase/GSNO reductase is responsive to wounding, jasmonic acid and salicylic acid (2003)

It has recently been discovered that glutathione-dependent formaldehyde dehydrogenase (FALDH) exhibits a strong S-nitrosoglutathione reductase activity. Plants use NO and S-nitrosothiols as signaling molecules to activate defense mechanisms. Therefore, it is interesting to investigate the regulation of FALDH by mechanical wounding and plant hormones involved in signal transduction. Our results show that the gene encoding FALDH in Arabidopsis (ADH2) is down-regulated by wounding and activated by salicylic acid (SA). In tobacco, FALDH levels and enzymatic activity decreased after jasmonate treatment, and increased in response to SA. This is the first time that regulation of FALDH in response to signals associated with plant defense has been demonstrated.
Cell cycle control and cancer: lessons from lung cancer. (1996)

Recent developments in the study of the cell cycle have shed much light on the origins of human cancer. We summarize these developments with an emphasis on the molecular characterization and the functional role of the cyclin-dependent kinase family of protein kinases (CDK) and their associated regulatory subunits. The Rb tumor suppressor in the progression from the G1 to S phase of the cell cycle and in tumor development is used as a paradigm for illustrating the importance of understanding the molecular regulatory events in the etiology of cancer. Recent developments with cyclin-dependent kinase inhibitors, most notably, p16 (CDKN2), indicate that these molecules represent new tumor suppressors in both skin and lung cancers. Insights from these cell cycle studies can provide avenues for the diagnosis, prognosis, and potential gene and chemotherapies for many cancers, including non-small cell lung cancer.
Notes on the Use of Plan Structures in the Creation of Interactive Plot (1999)

nd measurably indistinguishable from real world images.&quot; (Greenberg 1999)(pg. 45). The interface to a virtual space presents an abstracted, artificial representation of a world and the activities within it; it is the mimetic character of the space, together with our understanding that we are interacting with a mimetic artificat, that allows us as users to bring to bear all our knowledge of narrative understanding during our interaction (Brannigan 1992). When a user enters into a such a virtual space, it is as if a narrative contract is established between the user and the system&apos;s authors. 1 The contract establishes 1 See a compelling and much more extensive discussion by Kendal Walton on the role of mimesis and its relationship the expectation that the system will obey certain narrative conventions. In this way, the contract is beneficial to both designer and user. It facilitates the user&apos;s comprehension by licensing interpretation of experience
Sleep monitoring using an infrared thermal array sensor (2019)

Recently, sleep evaluation has attracted lots of attention as sleep disorders have become a public health problem that causes cumulative effect on physical and mental health. Poor sleep qualities can lead to adverse effects on performance of basic activities in normal life such as memorization, concertation and learning especially among elderlies. Sleep posture is one of the keys factors that evaluates sleep qualities to prevent medical conditions such as pressure ulcer formation. In this paper, a sleep monitoring system is developed based on an infrared array sensor to detect different sleep postures. Motion and presence detections are performed and achieved an accuracy over 90%. And eleven different postures can be successfully identified with an accuracy above 95% in controlled lab environment. As the infrared array sensor has the unique property of non-contact, non-privacy invasion and passive sensing, it provides an unobtrusive, low cost and convenient method of long-term sleep monitoring.
The factorization method for cracks in inhomogeneous media (2017)

We consider the inverse scattering problem of determining the shape and location of a crack surrounded by a known inhomogeneous media.Both the Dirichlet boundary condition and a mixed type boundary conditions are considered.In order to avoid using the background Green function in the inversion process, a reciprocity relationship between the Green function and the solution of an auxiliary scattering problem is proved.Then we focus on extending the factorization method to our inverse shape reconstruction problems by using far field measurements at fixed wave number.We remark that this is done in a non intuitive space for the mixed type boundary condition as we indicate in the sequel.
Provocation discography as a guide to planning operations on the spine (1988)

In a prospective study we attempted to define the role of lumbar discography in the investigation of patients with low back pain with or without non-dermatomal pain in the lower limb. The records of 195 patients were studied at least two years after a technically successful operation. Of 137 patients in whom discography had revealed disc disease and provoked symptoms, 89% derived significant and sustained clinical benefit from operation. Of 25 patients whose discs showed morphological abnormality but had no provocation of symptoms on discography only 52% had clinical success. These findings support the continued use of lumbar discography for the investigation of this particular group of patients.
Ocular motor involvement in post-infective polyneuropathy. (1977)

Ocular motor involvement is uncommon in post-infective polyneuropathy. Details of the evolution and recovery of the ophthalmoplegia are presented in 11 patients in whom ocular motor involvement was a major or notable feature of the illness. Follow-up examinations after intervals of up to 6 years in 10 of the 11 patients showed no residual ocular motor impairment. Saccadic eye movement studies carried out in 6 cases at the time of follow-up showed no abnormality in 2 cases while in the other 4 cases there was mild reduction of saccadic velocities and/or increased saccade reaction times with saccade inaccuracy. In spite of the variability of the ophthalmoplegia and of the remainder of the clinical syndrome in these cases, we conclude that they all represent variants of the classical form of the Guillain-Barre syndrome.
