Interference Mitigation for Broadcast in Hierarchical Cell Structure Networks: Transmission Strategy and Area Spectral Efficiency (2014)

In this paper, a hierarchical cell structure (HCS) is considered, where an access point (AP) broadcasts to local nodes (LNs) over orthogonal frequency subbands within a local cell located in a macrocell. Since the local cell shares the spectrum licensed to the macrocell, a given LN is interfered with by the macrocell user (MU)'s transmissions over the same subband. To improve the performance of the AP's broadcast service, a novel transmission strategy is proposed to mitigate the interference from the MU to the LN while achieving diversity gain. For the purpose of performance evaluation, the ergodic capacity of the proposed scheme is quantified, and the corresponding closed-form expression is obtained. By comparing with the traditional transmission scheme, which suffers from MU's interference, illustrative numerical results substantiate that the proposed scheme achieves better performance than the traditional scheme as the MU–LN mean channel power gain is larger than half of the AP–LN mean channel power gain. Subsequently, we develop an optimized network design by maximizing the area spectral efficiency (ASE) of the AP's broadcast in the local cell.
Intermanual Apparent Tactile Motion and Its Extension to 3D Interactions (2017)

Information provided by sensory systems is inherently ambiguous as to its source in the physical world. To arrive at a coherent representation, perception deploys heuristic rules and multimodal input, which potentially produce errors such as illusions. The current work uses these effects to create apparent tactile motion and illusory depth motion using sparse vibrotactile stimulation across the hands. Experiment 1 showed the effects of vibrotactile duration and temporal separation between the hands on the quality of perceived illusory linear motion. Experiment 2 indicated a compressed linear relation between the visual and tactile speeds, and established a linear function relating visual size to perceived tactile intensity at three durations. Experiment 3 introduced an "M-filter" algorithm that varies tactile stimulus amplitude by a parabolic function based on visual looming and receding. It demonstrated that the M-filters, accompanied by visual depth cues, can induce tactile motion in depth. Experiment 4 showed the M-filter algorithm is necessary to create tactile perception in depth, as opposed to apparent tactile motion. The current research has value for a basic understanding of haptic perception, as well as haptic applications that digitally generate perceptual representations of the distal world on small-sized devices in the space between the hands.

Preclinical Imaging for the Study of Mouse Models of Thyroid Cancer (2017)

Thyroid cancer, which represents the most common tumors among endocrine malignancies, comprises a wide range of neoplasms with different clinical aggressiveness. One of the most important challenges in research is to identify mouse models that most closely resemble human pathology; other goals include finding a way to detect markers of disease that common to humans and mice and to identify the most appropriate and least invasive therapeutic strategies for specific tumor types. Preclinical thyroid imaging includes a wide range of techniques that allow for morphological and functional characterization of thyroid disease as well as targeting and in most cases, this imaging allows quantitative analysis of the molecular pattern of the thyroid cancer. The aim of this review paper is to provide an overview of all of the imaging techniques used to date both for diagnosis and theranostic purposes in mouse models of thyroid cancer.
A saturation screen for cis-acting regulatory DNA in the Hox genes of Ciona intestinalis (2005)

A screen for the systematic identification of cis-regulatory elements within large (&gt;100 kb) genomic domains containing Hox genes was performed by using the basal chordate Ciona intestinalis. Randomly generated DNA fragments from bacterial artificial chromosomes containing two clusters of Hox genes were inserted into a vector upstream of a minimal promoter and lacZ reporter gene. A total of 222 resultant fusion genes were separately electroporated into fertilized eggs, and their regulatory activities were monitored in larvae. In sum, 21 separable cis-regulatory elements were found. These include eight Hox linked domains that drive expression in nested anterior-posterior domains of ectodermally derived tissues. In addition to vertebrate-like CNS regulation, the discovery of cis-regulatory domains that drive epidermal transcription suggests that C. intestinalis has arthropod-like Hox patterning in the epidermis.
Evidence for helicity in insect diuretic peptide hormones: computational analysis, spectroscopic studies, and biological assays (1999)

The conformation of four insect diuretic hormones has been analyzed computationally using secondary structure prediction routines and comparison with structures in the Brookhaven Protein Databank. Based on this analysis, a common seven-residue peptide fragment (DVLRQRL) had a high probability of forming an alpha-helix. Circular dichroism (CD) studies found that addition of trifluoroethanol (TFE) to an aqueous solution of the seven-residue fragment induces a change from random coil to helix. Subsequent NMR studies in water-TFE (1:1) produced nOe values and 3JalphaNH coupling constants confirming a helical conformation: 3JalphaNH coupling constants for the first five residues (D1 to Q5) were all < or = 6.0 Hz and two medium-range nOe values (dalphaN (i,i+3)) were observed between V2 and Q5, and R4 and L7. The longer fragments PLDVLRQRL in water-TFE and Lom-DH 1-26 in water alone, both containing the DVLRQRL sequence of the locust (Locusta migratoria) diuretic hormone, maintained the helicity as determined by CD analysis. However, the remaining 20 residues of the locust diuretic hormone did not maintain the same amount of helicity in water and all of the truncated fragments were not biologically active.
Partial Wetting of Aqueous Solutions on High Aspect Ratio Nanopillars with Hydrophilic Surface Finish (2014)

In semiconductor manufacturing, potential wetting issues with aqueous chemistries are becoming a concern as feature dimensions are continuously scaled down and novel materials with different wetting properties are introduced in new technology nodes. The wetting behavior of silicon nanopillars with different dimensions and surface modifications has been studied using static contact angle, decoration by etching, and attenuated total reflection infra-red spectroscopy (ATR-FTIR). The contact angle measurements showed a consistent deviation from the classic wetting models for patterned substrates with an hydrophilic surface termination. Under these conditions the decoration and ATR-FTIR studies gave evidence for partial wetting, with residual gas lasting for more than 30 min. It is proposed that this was resulting from the formation of long-lasting surface nanobubbles localized in-between or at the bottom of nanopillars. On the other hand the residual gas volume estimated by ATR-FTIR seemed too small to explain the contact angle deviations. It is proposed that the apparent extension of the superhydrophobic regime to lower contact angles resulted from modifications of the wettability of the surface of nanopillars caused by the manufacturing process. Both the formation of nanobubbles and the extension of the superhydrophobic regime may present challenges for aqueous cleaning in semiconductor manufacturing.
On ordering of fundamental wineglass modes in toroidal ring gyroscope (2016)

In this paper, we discuss the primary sources of frequency splits in degenerate mode Toroidal Ring Gyroscope (TRG) with isotropic concentric rings suspension. We show that operation in the n=3 “wineglass mode” might be preferable for prioritized device symmetry. We demonstrate that by means of structural design it is possible to achieve a desired order of wineglass modes, critical for vibration immunity, and potentially for improved performance of miniature devices. Mode-ordering is accomplished by a proper choice of a number of rings in the suspension and an angle between the spokes connecting the rings. The method of mode-ordering is confirmed through experimental characterization of 2.8 mm diameter TRG prototypes fabricated in <100> and <111> single crystal silicon.
Toward a Principled Framework for Benchmarking Consistency (2012)

Large-scale key-value storage systems sacrifice consistency in the interest of dependability (i.e., partition tolerance and availability), as well as performance (i.e., latency). Such systems provide eventual consistency,which---to this point---has been difficult to quantify in real systems. Given the many implementations and deployments of eventually-consistent systems (e.g., NoSQL systems), attempts have been made to measure this consistency empirically, but they suffer from important drawbacks. For example, state-of-the art consistency benchmarks exercise the system only in restricted ways and disrupt the workload, which limits their accuracy. In this paper, we take the position that a consistency benchmark should paint a comprehensive picture of the relationship between the storage system under consideration, the workload, the pattern of failures, and the consistency observed by clients. To illustrate our point, we first survey prior efforts to quantify eventual consistency. We then present a benchmarking technique that overcomes the shortcomings of existing techniques to measure the consistency observed by clients as they execute the workload under consideration. This method is versatile and minimally disruptive to the system under test. As a proof of concept, we demonstrate this tool on Cassandra.
Pomegranate nanoparticle mitigates cisplatin-induced testicular toxicity and improves cisplatin anti-cancer efficacy in Ehrlich carcinoma model (2023)

Cisplatin (CISP) ranks among the most used chemo-therapeutic agents with exceptional efficacy against testicular cancer among other diverse types of cancers. However, it has been associated with nephrotoxicity among other side effects. Pomegranate (PE) is an effective anti-inflammatory and antioxidant compound, protecting against several chemotherapy-linked toxicities. The use of PE are limited due to its low bioavailability and poor solubility. We investigated the potential of a novel nanoparticle (NP) encapsulating PE formulation to surmount its poor solubility, improve its bioavailability, and augment its protective efficacy against CISP-induced testicular toxicity in an Ehrlich solid carcinoma (ESC) mice model. All animals were randomly grouped into four treatment groups: 1) control, 2) tumor, 3) CISP, and 4) CISP + PE-NPs. The results obtained demonstrated that PE-NPs efficiently prevented testicular toxicity induced by CISP in ESC mice and enhanced its functions. PE-NPs effectively improved CISP-induced oxidative stress in testicular tissues by elevating the levels of antioxidants (GSH, SOD and CAT). Importantly, PE-NPs, also, substantially decreased testicular inflammation induced by CISP, via reducing the levels of IL-1β, TNF-α, and NF-kB. PE-NPs did not impede the CISP’s antitumor activity as shown by histological examination data and tumor weight. It is, therefore, conceivable that PE-NPs may serve as an adjuvant therapy to CISP in the treatment of cancer, to ameliorate the associated testicular toxicity and other unwanted effects without compromising the antitumor efficacy of CISP.
Impacted Science: Impact Is Not Importance (2015)

The journal impact factor (IF) exerts a tremendous influence on the conduct of scientists. The obsession with IF has been compared to a medical condition, sometimes referred to as "IF mania" or "impactitis." Here, we analyze the difference between impact and importance, using examples from the history of science to show that these are not equivalent. If impact does not necessarily equal importance, but scientists are focused on high-impact work, there is a danger that misuse of the IF may adversely affect scientific progress. We suggest five measures to fight this malady: (i) diversify journal club selections, (ii) do not judge science on the publication venue, (iii) reduce the reliance on journal citation metrics for employment and advancement, (iv) discuss the misuse of the IF in ethics courses, and (v) cite the most appropriate sources. If IF mania is indeed a medical condition, the most appropriate course of action may be disimpaction.

The effect of capping agents on the toxicity of silver nanoparticles to Danio rerio embryos (2019)

Addition of capping agents like surfactants and polymers during the synthesis of nanoparticles may affect the stability and toxicity of dispersions of nanoparticles. This study revealed the impact of anionic, cationic, and amphoteric surfactants and a cationic polymer on the physical and chemical properties, stability and behavior of silver nanomaterials, as well as on the toxicity of nanosized silver particles with respect to zebrafish embryos. Some of the stabilizers applied were shown to significantly affect embryos of Danio rerio. Colloidal dispersions of stabilized silver nanoparticles were demonstrated to induce a complex mechanism of toxicity with respect to embryos of D. rerio, which is mainly explained by the toxicity of the organic ligand, while other parameters are somewhat inferior. The newly generated data on the toxicity of nanoparticles and their stabilizers with respect to D. rerio embryos reveal the complexity of the toxicity mechanism of nanoparticles impacting living systems.

Estimation of source location of leakage field from transformer-type microwave oven (2004)

A method to estimate the source location based on the MUSIC algorithm is proposed and is applied to the electromagnetic field emitted by a microwave oven of the transformer-type. Since the frequency, the phase and the amplitude of the leakage field emitted by a microwave oven change with time, a detection method using the periodicity of the field is also proposed to obtain the phase distribution. Experimental results are shown of the estimation of the source location using the proposed method.
A Perspective on the Synthesis, Purification, and Characterization of Porous Organic Cages (2016)

Porous organic cages present many opportunities in functional materials chemistry, but the synthetic challenges for these molecular solids are somewhat different from those faced in the areas of metal-organic frameworks, covalent-organic frameworks, or porous polymer networks. Here, we highlight the practical methods that we have developed for the design, synthesis, and characterization of imine porous organic cages using <b>CC1</b> and <b>CC3</b> as examples. The key points are transferable to other cages, and this perspective should serve as a practical guide to researchers who are new to this field.
Design, development and validation of an NS2 module for dynamic LSP rerouting (2006)

The major goal of traffic engineering (TE) is to enable efficient and reliable network operations while optimizing resource utilization and network performance. Extensions to interior gateway protocols (IGPs) are necessary since further information, such as link status and administrative policies, must be distributed among routers. The paper discusses the design and development, for the Network Simulator 2 (NS2), of a new software module to support both the CSPF algorithm and TE extensions to OSPF. This module enhances NS2 with new fundamental functionalities, such as dynamically rerouting label switched paths (LSPs), taking into account TE metrics. Finally, to assess the OSPF-TE module, we show the results of some simulations performed to evaluate the recovery time in MPLS networks
Not all dementias are equally created: Tailored translational research differentially addresses unanswered questions (2022)

Advances in the diagnostics of various dementias, including Alzheimer's disease (AD), Dementia with Lewy Bodies (DLB), Parkinson's disease dementia (PDD), clinical and behavioral variants of Frontotemporal Lobar Degeneration (FLD) and Parkinsonism with dementia, i.e., corticobasal degeneration (CBD) etc. have led to some understanding of the distinct and perhaps disparate anatomical, molecular and pathological pathways of dementia. Anatomical and molecular imaging, longitudinal post-mortem specimen studies and bio fluids (plasma, cerebrospinal fluid, tear, saliva, skin biopsies etc.) analysis all contributed to a thematic understanding that divergent neuropathology may lead to differential diagnoses that are underscored by dementia as a common denominator. While various methodologies are important in elucidating relevant mechanisms of dementia, a translational approach that takes into account a specific patient population could provide more adequate frontiers to establish precision of diagnosis and greater effectiveness of dementia therapeutics. In this context, translational research is a two-way process that uses pre-clinical science, technology and advances in various methodologies to validate mechanisms of human disease in reference to observational and clinical data, including clinical practice and clinical trials, as well as biomarker analysis, to support an innovative approach to advance dementia-specific therapies.
Practical Synthesis of a Heterocyclic Immunosuppressive Vitamin D Analogue (2007)

1α,25-Dihydroxyvitamin D3 (calcitriol) 1 and synthetic analogues thereof are highly potent compounds with a wide range of pharmacological activity making them of great interest for the pharmaceutical industry. Herein we report an improved synthesis of the calcitriol analogue 2, which features a novel oxazole-containing side chain. The crucial part of the synthesis was the development of a practical route to the β-keto phosphonate 28, allowing an easy introduction of the unnatural side chain by a Wittig Horner reaction.
Resource Allocation Techniques for Wireless Powered Communication Networks With Energy Storage Constraint (2015)

This paper studies multiuser wireless powered communication networks, where energy constrained users charge their energy storages by scavenging energy of the radio frequency signals radiated from a hybrid access point (H-AP). The energy is then utilized for the users' uplink information transmission to the H-AP in time division multiple access mode. In this system, we aim to maximize the uplink sum rate performance by jointly optimizing energy and time resource allocation for multiple users in both infinite capacity and finite capacity energy storage cases. First, when the users are equipped with the infinite capacity energy storages, we derive the optimal downlink energy transmission policy at the H-AP. Based on this result, analytical resource allocation solutions are obtained. Next, we propose the optimal energy and time allocation algorithm for the case where each user has finite capacity energy storage. Simulation results confirm that the proposed algorithms offer about 30% average sum rate performance gain over conventional schemes.
