PFG-NMR Investigations of the Binding of Cationic Neuropeptides to Anionic and Zwitterionic Micelles (2004)

The mechanism by which peptides bind to micelles is believed to be a two-phase process, involving (i). initial electrostatic interactions between the peptide and micelle surface, followed by (ii). hydrophobic interactions between peptide side chains and the micelle core. To better characterize the electrostatic portion of this process, a series of pulse field gradient nuclear magnetic resonance (PFG-NMR) spectroscopic experiments were conducted on a group of neuropeptides with varying net cationic charges (+1 to +3) and charge location to determine both their diffusion coefficients and partition coefficients when in the presence of detergent micelles. Two types of micelles were chosen for the study, namely anionic sodium dodecylsulfate (SDS) and zwitterionic dodecylphosphocholine (DPC) micelles. Results obtained from this investigation indicate that in the case of the anionic SDS micelles, peptides with a larger net positive charge bind to a greater extent than those with a lesser net positive charge (bradykinin > substance P > neurokinin A > Met-enkephalin). In contrast, when in the presence of zwitterionic DPC micelles, the degree of mixed-charge nature of the peptide affects binding (neurokinin A > substance P > Met-enkephalin > bradykinin). Partition coefficients between the peptides and the micelles follow similar trends for both micelle types. Diffusion coefficients for the peptides in SDS micelles, when ranked from largest to smallest, follow a trend where increasing net positive charge results in the smallest diffusion coefficient: Met-enkephalin > neurokinin A > bradykinin > substance P. Diffusion coefficients when in the presence of DPC micelles, when ranked from largest to smallest, follow a trend where the presence of negatively-charged side chains results in the smallest diffusion coefficient: bradykinin > Met-enkephalin > substance P > neurokinin A.
Local peak enhancement combined with noise reduction algorithms for robust automatic speech recognition in automobiles (2008)

The accuracy of automatic speech recognition in automobiles is significantly degraded in very low SNR (Signal to Noise Ratio) situations such as “Fan high” or “Window open”. In such cases, speech signals are often buried in broadband noise. In this paper, we propose a novel approach for such situations that utilizes harmonic structures in the human voice. It pursues two objectives. (1) Unlike comb filtering, it should not rely on F0 detection or voiced/unvoiced detection, since they are not accurate enough in noisy environments. (2) It should work with existing noise reduction algorithms. In our new approach, an observed power spectrum is directly converted into a filter for speech enhancement by retaining only the local peaks considered to be harmonic structures. In our experiments, we reduced the word error rate significantly in realistic automobile environments, and our approach showed further improvements when used with existing noise reduction algorithms.
Bit-Per-Joule Performance of Power Saving Ad Hoc Networks under Mobile Backbone Coverage (2006)

Energy efficient MAC protocols have been developed for wireless sensor and ad hoc networks so that inactive nodes can transition to sleep state to conserve energy. It has been recognized that forming and keeping a continuously awake Connected Dominating Set (CDS) serves to significantly reduce the route setup latency (since it minimizes the number of wakeup operations that are undertaken). Recently published studies show that, under certain traffic conditions, the CDS approach can lead to the reduction of the average level of energy consumption while ensuring a high network throughput level. Under the Mobile Backbone Network (MBN) architecture introduced by I. Rubin et al., a mobile backbone is dynamically constructed to provide a topological covering of the network. Nodes that join the mobile backbone are identified as Backbone Nodes (BNs). In this paper, we study a MBN Power Saving (MBN-PS) system. The dynamically elected BNs are kept active and are used to effectively manage the awake and sleep states of their client nodes. We study the throughput (per-watt) efficiency performance of the MBN-PS protocol by analytical calculations, as well as by extensive simulation evaluations. We analytically show that when the number of active network flows is above a minimal level, the underlying throughput efficiency attained by the MBN-PS scheme is better than that achieved by a corresponding network that does not form a backbone structure.

Preparing students for democratic citizenship: Codes of conduct in Victoria’s ‘Schools of the Future’ (1999)

Recent Australian experience of decentralisation in education has many parallels with contemporary movements in a number of other western democratic nations. Within the State of Victoria, Australia, all schools have developed, at local community level, school charters which address the school’s goals, policies, priorities, curriculum, and standards. This article reports an analysis of one component of almost 300 schools’ charters; namely codes of conduct for student behaviour. The results indicate a need for schools to emphasise a closer connection between students’ rights and their responsibilities. Secondly, the many schools intending to implement an assertive or authoritarian approach to discipline are failing to balance their planned use of punishments with corresponding rewards and recognition. Thirdly, the political relevance of the style of discipline develop chosen by local school communities appears incompatible with an education likely to develop democratic citizens.
Segregation of oxygen vacancy at metal-HfO2 interfaces (2008)

We perform first-principles calculations on metal-HfO2 interfaces in the presence of oxygen vacancies. Pt, Al, Ti, and Ag are considered as electrodes. It is found that oxygen vacancies are strongly attracted to the interface with binding energies of up to several eVs. In addition, the vacancy affinity of interfaces is proportional to the work function of metals, which is understood by the transition level of the vacancy and metal-Hf bonding. Interfacial segregation of vacancies significantly affects effective work functions of p metals. Our results are consistent with flatband shifts in p-type field effect transistors employing high-k dielectrics and metal gates.
Inhibition of HIF‐1 alpha and VEGF expression by the chemopreventive bioflavonoid apigenin is accompanied by Akt inhibition in human prostate carcinoma PC3‐M cells (2008)

Progression of cancer leads to hypoxic solid tumors that mount specific cell signaling responses to low oxygen conditions. An important objective of anti-cancer therapy is the development of new drugs that suppress hypoxic responses in solid tumors. Apigenin is a natural flavone that has been shown to have chemopreventive and/or anti-cancer properties against a number of tumor types. However, the mechanisms underlying apigenin's chemopreventive properties are not yet completely understood. In this study, we have investigated the effects of apigenin on expression of hypoxia-inducible factor-1 (HIF-1) in human metastatic prostate PC3-M cancer cells. We found that hypoxia induced a time-dependent increase in the level of HIF-1alpha subunit protein in PC3-M cells, and treatment with apigenin markedly decreased HIF-1alpha expression under both normoxic and hypoxic conditions. Further, apigenin prevented the activation of the HIF-1 downstream target gene vascular endothelial growth factor (VEGF). We then showed that apigenin inhibited expression of HIF-1alpha by reducing stability of the protein as well as by reducing the level of HIF-1alpha mRNA. We also found that apigenin inhibited Akt and GSK-3beta phosphorylation in PC3-M cells. Further experiments demonstrated that constitutively active Akt blunted the effect of apigenin on HIF-1alpha expression. Taken together, our results identify apigenin as a bioflavonoid that inhibits hypoxia-activated pathways linked to cancer progression in human prostate cancer, in particular the PI3K/Akt/GSK-3 pathway. Further studies on the mechanism of action of apigenin will likely provide new insight into its applicability for pharmacologic targeting of HIF-1alpha for cancer therapeutic or chemopreventive purposes.

Shape Estimation Using Polarization and Shading from Two Views (2007)

This paper presents a novel method for 3D surface reconstruction that uses polarization and shading information from two views. The method relies on polarization data acquired using a standard digital camera and a linear polarizer. Fresnel theory is used to process the raw images and to obtain initial estimates of surface normals, assuming that the reflection type is diffuse. Based on this idea, the paper presents two novel contributions to the problem of surface reconstruction. The first is a technique to enhance the surface normal estimates by incorporating shading information into the method. This is done using robust statistics to estimate how the measured pixel brightnesses depend on the surface orientation. This gives an estimate of the object material reflectance function, which is used to refine the estimates of the surface normals. The second contribution is to use the refined estimates to establish correspondence between two views of an object. To do this, a set of patches are extracted from each view and are aligned by minimizing an energy functional based on the surface normal estimates and local topographic properties. The optimum alignment parameters for different patch pairs are then used to establish stereo correspondence. This process results in an unambiguous field of surface normals, which can be integrated to recover the surface depth. Our technique is most suited to smooth, non-metallic surfaces. It complements existing stereo algorithms since it does not require salient surface features to obtain correspondences. An extensive set of experiments, yielding reconstructed objects and reflectance functions, are presented and compared to ground truth.
Orthogonal Frequency Division Multiplexing With Index Modulation (2013)

In this paper, a novel orthogonal frequency division multiplexing (OFDM) scheme, called OFDM with index modulation (OFDM-IM), is proposed for operation over frequency-selective and rapidly time-varying fading channels. In this scheme, the information is conveyed not only by M-ary signal constellations as in classical OFDM, but also by the indices of the subcarriers, which are activated according to the incoming bit stream. Different low complexity transceiver structures based on maximum likelihood detection or log-likelihood ratio calculation are proposed and a theoretical error performance analysis is provided for the new scheme operating under ideal channel conditions. Then, the proposed scheme is adapted to realistic channel conditions such as imperfect channel state information and very high mobility cases by modifying the receiver structure. The approximate pairwise error probability of OFDM-IM is derived under channel estimation errors. For the mobility case, several interference unaware/aware detection methods are proposed for the new scheme. It is shown via computer simulations that the proposed scheme achieves significantly better error performance than classical OFDM due to the information bits carried by the indices of OFDM subcarriers under both ideal and realistic channel conditions.
CONVENTIONAL VERSUS SPECTROPHOTOMETRIC SHADE TAKING FOR THE UPPER CENTRAL INCISOR: A CLINICAL COMPARATIVE STUDY (2010)

Introduction: Restoration of a single upper central incisor is one of the most challenging situations for the dentist-dental technician team. Proper selection, communication and more accurate color reproduction of the upper central incisor is the key to a successful prosthodontic treatment. The objective of this study was to determine the inter-observer variability in shade selection for the upper central incisor when using two shade guides (Vita Classic and Vitapan 3D Master) and to compare the results with those of Vita Easy Shade spectrophotometer. Material and method: The study involved 26 students of the Faculty of Dentistry, who examined the color of central incisor for 4 patients with conventional shade guides. Standard conditions were used to choose the color and determinations were made independently by two shade guides, Vita Classic and Vita 3D Master. The results were compared with those obtained by using the Vita Easy Shade spectrophotometer. The IBM SPSS Statistics (Version 19) software was used to statistically compare the results of the students with the spectrophotometer results. Results: A frequencies analysis concluded that the correlation percentage between the determinations of the students and the spectrophotometer was 37.5% for both Vita Classic and Vitapan 3D Master shade guide. Conclusion: this study showed that there are some large variations in color determination for the upper central incisor by using 2 conventional shade guides and the spectrophotometer may be a useful educational tool.
Connectionless broadcast channel and mobility of Bluetooth (2003)

This paper proposes a new mechanism for Bluetooth connectionless broadcast channel and concept of net access point (NAP) segment. They are used to track location of idle personal area network users (PANU) in power and radio resource save manner. The connectionless broadcast channel is separated into beacon window and broadcast window. During the beacon window, NAP spreads an extended ID packet that includes BD ADDR and clock offset to synchronize all PANU in its radio range. The Extended ID packet is the standard ID packet with extra information field at the end. Then, any user-defined information is released in the broadcast window from NAP to PANU without connection establishment between NAP and PANU. The NAP segment is a set of geography neighbor NAP. When an idle PANU moves within a NAP segment, no handover is needed even when the current connection breaks. When an idle PANU moves across the NAP segment, handover must be performed to register the PANU's location. We present an analysis of PANU mobility with and without the NAP segment to show that the NAP segment can save the radio resources of the NAP and power consumption of the PANU.
On the Use of Complementary Spectral Features for Speaker Recognition (2007)

The most popular features for speaker recognition are Mel frequency cepstral coefficients (MFCCs) and linear prediction cepstral coefficients (LPCCs). These features are used extensively because they characterize the vocal tract configuration which is known to be highly speaker-dependent. In this work, several features are introduced that can characterize the vocal system in order to complement the traditional features and produce better speaker recognition models. The spectral centroid (SC), spectral bandwidth (SBW), spectral band energy (SBE), spectral crest factor (SCF), spectral flatness measure (SFM), Shannon entropy (SE), and Renyi entropy (RE) were utilized for this purpose. This work demonstrates that these features are robust in noisy conditions by simulating some common distortions that are found in the speakers' environment and a typical telephone channel. Babble noise, additive white Gaussian noise (AWGN), and a bandpass channel with 1 dB of ripple were used to simulate these noisy conditions. The results show significant improvements in classification performance for all noise conditions when these features were used to complement the MFCC and MFCC features. In particular, the SC and SCF improved performance in almost all noise conditions within the examined SNR range (10–40 dB). For example, in cases where there was only one source of distortion, classification improvements of up to 8% and 10% were achieved under babble noise and AWGN, respectively, using the SCF feature.
High Response Rate to Lenalidomide in Relapsed/Refractory Aggressive Non-Hodgkin’s Lymphoma with Prior Stem Cell Transplant. (2007)

Abstract Background: High dose chemotherapy with stem cell transplant is currently employed in relapsed/refractory aggressive Non-Hodgkin’s Lymphoma (NHL). Lenalidomide (Revlimid®), an immunomodulatory drug, has shown activity in hematological malignancies including relapsed/refractory multiple myeloma, chronic lymphocytic leukemia and cutaneous T-cell lymphoma. Aim: To determine the activity and safety of lenalidomide monotherapy in relapsed/refractory aggressive NHL following stem cell transplant (SCT). Methods: Patients with relapsed/refractory aggressive NHL with measurable disease ≥ 2 cm after at least 1 prior treatment regimen were eligible. Patients received 25 mg lenalidomide orally once daily on Days 1–21 every 28 days and continued therapy for 52 weeks as tolerated or until disease progression. Response and progression were evaluated using the IWLRC methodology. Results: Fourteen (29%) of the 49 patients enrolled into the study had a prior SCT. Median age was 61 (23–76) and 5 were female. Histology was diffuse large B-cell lymphoma [DLBCL] (n=5), follicular center lymphoma grade 3 [FL] (n=2), mantle cell lymphoma [MCL] (n=5) and transformed [TSF] (n=2). Median time from diagnosis to lenalidomide was 3.9 (1.1–31.4) years and median time from SCT to study entry was 1.9 (0.5–11.7) years. The median number of prior treatment regimens was 5 (2–8). Seven patients (50%) exhibited an objective response (1 complete response unconfirmed (CRu), and 6 partial responses (PR)), 5 had stable disease (SD) and 2 patients had progressive disease (PD). Six responses were in eight patients having a tumor burden &lt; 50 cm2 and a time since last rituximab therapy of ≥ 230 days. One response was achieved in six patients having a tumor burden ≥ 50 cm2 or a time since last rituximab therapy of &lt; 230 days. Four of 6 (67%) patients who had SCT as their last treatment prior to lenalidomide [median time from SCT to lenalidomide = 0.8 (0.5–4.8) years] responded. Progression free survival [PFS] is 4.5 months and ongoing. Six patients (43%) required at least one dose reduction with a median time to first dose reduction of 1.6 months (0.4–4.9). Two patients each (14%) had Grade 4 adverse events of neutropenia and thrombocytopenia. The most common Grade 3 adverse events were neutropenia (36%), thrombocytopenia (21%), and leukopenia (14%). Conclusion: Lenalidomide produced a 50% response rate with manageable side effects in relapsed/refractory aggressive NHL following stem cell transplant.
Rheological Evaluation of Maturing Cheddar Cheese (1982)

ABSTRACT A number of Cheddar cheese samples of different age, pH and moisture content have been examined rheologically and electrophoretically to determine whether the progressive changes in cheese texture were related to casein proteolysis. The force‐compression curves obtained by crushing cubes of cheese between small flat plates at constant speed were different for the different cheese samples and were affected by the moisture content, pH and extent of α sl ‐casein proteolysis that had taken place in the cheese. These results support a model of cheese micro structure in which an extensive network involving α sl ‐ casein molecules traverses the cheese and as the cheese ripens, chymosin cleavage of α sl ‐casein weakens the protein network. Such a model explains the rapid decrease in Cheddar cheese yield‐force that occurs during the early stages of ripening.
Striatal D<sub>1</sub> and D<sub>2</sub> receptor binding in patients with Huntington's disease and other choreas A PET study (1995)

We have used PET to study striatal D1 and D2 receptor binding in 10 patients with either the choreic or akinetic-rigid variants of Huntington's disease and in three patients with other causes of chorea. Background rigidity and bradykinesia in choreic patients were scored with a four-point scale. PET studies showed a severe and parallel reduction of both striatal D1 and D2 receptor binding in Huntington's disease patients irrespective of their predominant phenotype (mean reduction 60%). Huntington's disease patients with rigidity showed more pronounced reduction of striatal D1 and D2 binding compared with those without rigidity. A case of chorea associated with systemic lupus erythematosus had normal D2 binding. These results suggest that the presence of chorea per se may not be determined by alterations in striatal dopamine receptor binding, but that rigidity in Huntington's disease is associated with severe striatal D1 and D2 receptor loss.
