Reducing power consumption of cellular networks by using various cell types and cell zooming (2014)

Nowadays, it is urgent to manage the power consumption in cellular networks due to the increased amounts of CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> . As a result, this increased amount of CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> released leads to severe threats for global warming and to an increase in the energy cost in the base stations. This problem arouse as soon as the evolution of mobile networks emerged especially in the last decades. As a result, we have witnessed a massive growth in the number of base stations all over the world in order to serve these highly increasing demands on cellular traffic. Hence, mobile operators need to meet these new demands in wireless cellular networks, while they have to maintain reasonable costs to keep high benefits and maintain high quality of service at in addition to decreasing energy consumption. This is the concept of Green Communication. In our paper, we propose a new solution that will help in reducing energy consumption. The solution is a centralized algorithm applied in a heterogeneous Long Term Evolution (LTE) network using Macro and Micro base stations, applied with a new Control Server that will be implemented using a newly introduced server in evolved cellular networks.

Precision imaging for biosensing (INVITED) (2007)

Precision imaging is a collection of image sensing techniques involving ultra-high sensitivity, time accuracy, and dynamic range, as well as ultra-low noise. In fact, imaging biological processes often requires sub-milli-lux sensitivity to detect tiny levels of bioluminescence or time-correlated techniques to precisely evaluate the decay time of a fluorophore. In this paper we explore the impact precision imaging will likely have on bioimaging and medical imaging. We also describe VLSI techniques that could enable precision imaging devices in the short and medium term and their relevance to the field of imaging as a whole.
Phase 1b study of tarlatamab, a half-life extended bispecific T-cell engager (HLE BiTEimmune therapy) targeting DLL3, in de novo or treatment emergent neuroendocrine prostate cancer (NEPC). (2022)

TPS197 Background: NEPC is an aggressive cancer with no standard treatment approach and poor prognosis. It is usually treatment-emergent, occurring in 15%–20% of patients (pts) with metastatic castration-resistant prostate cancer following treatment with androgen signaling inhibitors (ASI) and is characterized by histological transformation from adenocarcinoma to a high-grade neuroendocrine tumor. 1 The tumor associated antigen delta-like ligand 3 (DLL3) has been identified as a promising target in both NEPC and small cell lung cancer (SCLC), as it is highly expressed in these tumors and minimally expressed on normal tissue. Tarlatamab is a DLL3-targeting HLE BiTE ® immune therapy designed to bind DLL3 on cancer cells and CD3 on T cells, resulting in T cell activation and expansion and T cell-dependent killing of tumor cells. In preclinical studies, tarlatamab induced T-cell dependent lysis of DLL3-expressing neuroendocrine tumor cell lines, including NEPC cells. 2 Interim results of an ongoing first-in-human study in pts with SCLC (NCT03319940) show evidence for tarlatamab efficacy with an acceptable safety profile. 3 Together, these findings support a clinical study of tarlatamab in NEPC. Methods: NCT04702737 is an open-label, phase 1b study evaluating tarlatamab infusion in pts with metastatic de novo or treatment-emergent NEPC, consisting of dose exploration and then dose expansion. Key eligibility criteria include adults (≥18 y) with metastatic NEPC whose disease progressed/recurred after ≥1 prior line of systemic therapy (platinum-based regimen for de novo NEPC or an ASI if treatment-emergent), measurable disease per RECIST 1.1 with Prostate Cancer Working Group 3 modifications, and ECOG performance status ≤2. Primary objectives are to evaluate safety and tolerability and determine the maximum tolerated dose or recommended phase 2 dose of tarlatamab. Secondary objectives are to evaluate antitumor activity (as assessed by objective response, duration of response, progression-free survival, overall survival, and disease control rate) and characterize pharmacokinetics. Four US and international study sites have been activated with two enrolled pts. References: Aggarwal R, et al. J Clin Oncol. 2018;36:2492-2503. Cooke K, et al. Abstract 627.

Maximizing the Dimensionality of Orbital Angular Momentum Entanglement in Parametric Down-conversion (2012)

The process of spontaneous parametric down-conversion is a dependable source of high-dimensional orbital angular momentum-entangled bi-photon states. We observe, analyze and maximize the number of orbital angular momentum modes produced by the down-conversion nonlinear crystal and detected by our measurement apparatus.
Neurologic Complications in Children with Enterovirus 71 Infection (1999)

In the 1998 enterovirus 71 epidemic in Taiwan, the chief neurologic complication was rhombencephalitis, which had a fatality rate of 14 percent. The most common initial symptoms were myoclonic jerks, and MRI usually showed evidence of brainstem involvement.
A note on: Spline technique for modeling roadway profile to minimize earthwork cost (2010)

The gap constraint used in A. A. Moreb, Spline technique for modeling roadway profile to minimize earthwork cost, J. Ind. Man. & Opt., 5 (2) (2009), 275-283 introduces unnecessary errors, while the slopeconstraint may be violated for second- and higher-order splines. In this note we amend the gap constraint, whilemaintaining the linearity of the model. We also present an improved slope constraint forlinear and quadratic splines, and show that it becomes nonlinear for cubic andhigher order splines. The improvements also apply to A. Moreb, M. Aljohani, Quadratic representation for roadway profile that minimizes earthwork cost, J. Sys. Sci. & Sys. Eng., 13 (2) (2004), 245-252.
Fisheye lens distortion correction on multicore and hardware accelerator platforms (2010)

Wide-angle (fisheye) lenses are often used in virtual reality and computer vision applications to widen the field of view of conventional cameras. Those lenses, however, distort images. For most real-world applications the video stream needs to be transformed, at real-time (20 frames/sec or better), back to the natural-looking, central perspective space. This paper presents the implementation, optimization and characterization of a fisheye lens distortion correction application on three platforms: a conventional, homogeneous multicore processor by Intel, a heterogeneous multicore (Cell BE), and an FPGA implementing an automatically generated streaming accelerator. We evaluate the interaction of the application with those architectures using both high- and low-level performance metrics. In macroscopic terms, we find that todays mainstream conventional multicores are not effective in supporting real-time distortion correction, at least not with the currently commercially available core counts. Architectures, such as the Cell BE and FPGAs, offer the necessary computational power and scalability, at the expense of significantly higher development effort. Among these three platforms, only the FPGA and a fully optimized version of the code running on the Cell processor can provide realtime processing speed. In general, FPGAs meet the expectations of performance, flexibility, and low overhead. General purpose multicores are, on the other hand, much easier to program.
Bandwidth enhancement of microstrip patch antenna using parasitic patch (2017)

Microstrip patch antenna finds a better choice in wireless communications because of their less cost, light weight and ease of fabrication. This paper proposes a novel design for the bandwidth enhancement of microstrip patch antenna with parasitic patch placed adjacent to the radiating patch along with the slots. The proposed structure is designed at 8.5 GHz using FR4-epoxy as substrate material that has relative permittivity 4.4 and loss tangent 0.02. HFSS (High Frequency Structure Simulator) software is used for simulating the proposed design. This antenna obtained the return loss -41.4.30 dB, gain 5.3542 dB, directivity 5.4612 dB and VSWR 1.0172. Comparative analysis with various slots on both main patch and parasitic patch has been done for various antenna parameters like; return loss, gain, directivity and VSWR. The results clearly explain that the proposed design has favourable characteristics suitable for X-band applications.

Beam tracking approach for single–shot retrieval of absorption, refraction, and dark–field signals with laboratory x–ray sources (2015)

We present the translation of the beam tracking approach for x–ray phase–contrast and dark–field imaging, recently demonstrated using synchrotron radiation, to a laboratory setup. A single absorbing mask is used before the sample, and a local Gaussian interpolation of the beam at the detector is used to extract absorption, refraction, and dark–field signals from a single exposure of the sample. Multiple exposures can be acquired when high resolution is needed, as shown here. A theoretical analysis of the effect of polychromaticity on the retrieved signals, and of the artifacts this might cause when existing retrieval methods are used, is also discussed.
Speech recognition using dynamic neural networks (2003)

The authors present an algorithm for isolated-word recognition that takes into consideration the duration variability of the different utterances of the same word. The algorithm is based on extracting acoustical features from the speech signal and using them as the input to a sequence of multilayer perceptron neural networks. The networks were implemented as predictors for the speech samples for a certain duration of time. The networks were trained by a combination of the back-propagation and the dynamic time warping (DTW) techniques. The DTW technique was implemented to normalize the duration variability. The networks were trained to recognize the correct words and to reject the wrong words. The training set consisted of ten words, each uttered seven times by three different speakers. The test set consisted of three utterances of each of the ten words. The results show that all these words could be recognized.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Novel cinchona carbamate selectors with complementary enantioseparation characteristics for N-acylated amino acids (2003)

The synthesis and chromatographic evaluation of the enantiomer separation capabilities of covalently immobilized calix[4]arene-cinchona carbamate hybrid type receptors derived from quinine (QN) and its corresponding C9-epimer (eQN) in different solvents are reported. The receptors display complementary enantiomer separation profiles in terms of elution order, chiral substrate specificity, and mobile phase characteristics, indicating the existence of two distinct chiral recognition mechanisms. The QN-derived receptor binds the (S)-enantiomers of N-acylated amino acids more strongly, shows preferential recognition of open-chained amino acids, and superior enantioselectivity in polar media such as methanol/acetic acid. In contrast, the eQN congener preferentially recognizes the corresponding (R)-enantiomers, displays good enantioselectivity (alpha up to 1.74) for cyclic amino acids, and enhanced stereodiscriminating properties in apolar mobile phases, e.g., chloroform/acetic acid. A comparison of the enantiomer separation profiles with those of the corresponding QN and eQN tert-butyl carbamate congeners indicates no significant level of cooperativity between the calix[4]arene module and the cinchona units in terms of overall chiral recognition, most probably as a consequence of residual conformational flexibility of the calixarene module and the carbamate linkage.
From planar to vertical capacitors: A step towards ferroelectric V-FeFET integration (2017)

Ferroelectric hafnium oxide (HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> )attracted a lot of interests since its discovery in 2007. Its scalability and CMOS compatibility are two advantages over conventional ferroelectric materials, favoring new device integration. Doped ferroelectric HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> Metal/Insulator/Metal capacitors have been widely studied for DRAM and FeFET applications. Silicon electrodes have not been discussed in much detail so far, though it provides an input for vertical ferroelectric FET (V-FeFET), based on Flash NAND architecture. In this work, planar and vertical capacitors are presented using silicon as electrodes and aluminum doped HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> as ferroelectric material. The process of the vertical integration is described. Polarization-Voltage measurements show a steep ferroelectric hysteresis loop for the planar as well as vertical capacitors. This demonstrates the conservation of the ferroelectric properties of the dielectric after deposition on an etched vertical wall and lays the first stone toward V-FeFET integration.
Investigation of a differential cryptanalysis inspired approach for Trojan AI detection (2021)

Deep Learning (DL) is becoming a popular paradigm in a broad category of decision systems that are crucial to the well-being of our society. Self-driving vehicles, online dating, social network content recommendation, chest X-Ray screening, etc. are all examples that show how the quality of our lives is tied to the decisions of these systems. We must take into account that these systems may be gamed to make favorable decisions for unqualified instances by malicious actors. For instance, if a self-driving car's traffic-sign detection model can classify a traffic stop sign as speed-limit if the pattern that triggers the faulty behavior is present. Our initial investigation result show, given we can generate/access a rich and high-quality dataset of random images, we may be able to build meta-models that can distinguish the poisoned/clean models with acceptable performance.
Correlation of phenotype with genotype and protein structure in RYR1-related disorders (2018)

Variants in the skeletal muscle ryanodine receptor 1 gene (RYR1) result in a spectrum of RYR1-related disorders. Presentation during infancy is typical and ranges from delayed motor milestones and proximal muscle weakness to severe respiratory impairment and ophthalmoplegia. We aimed to elucidate correlations between genotype, protein structure and clinical phenotype in this rare disease population. Genetic and clinical data from 47 affected individuals were analyzed and variants mapped to the cryo-EM RyR1 structure. Comparisons of clinical severity, motor and respiratory function and symptomatology were made according to the mode of inheritance and affected RyR1 structural domain(s). Overall, 49 RYR1 variants were identified in 47 cases (dominant/de novo, n = 35; recessive, n = 12). Three variants were previously unreported. In recessive cases, facial weakness, neonatal hypotonia, ophthalmoplegia/paresis, ptosis, and scapular winging were more frequently observed than in dominant/de novo cases (all, p < 0.05). Both dominant/de novo and recessive cases exhibited core myopathy histopathology. Clinically severe cases were typically recessive or had variants localized to the RyR1 cytosolic shell domain. Motor deficits were most apparent in the MFM-32 standing and transfers dimension, [median (IQR) 85.4 (18.8)% of maximum score] and recessive cases exhibited significantly greater overall motor function impairment compared to dominant/de novo cases [79.7 (18.8)% vs. 87.5 (17.7)% of maximum score, p = 0.03]. Variant mapping revealed patterns of clinical severity across RyR1 domains, including a structural plane of interest within the RyR1 cytosolic shell, in which 84% of variants affected the bridging solenoid. We have corroborated genotype-phenotype correlations and identified RyR1 regions that may be especially sensitive to structural modification.
Nano Catalyst for CO2 Conversion to Hydrocarbons (2015)

A supported trimetallic nano catalyst and a fixed bed catalytic process have been developed for the conversion of CO2 + H2O (in the form of steam) + 1 % H2 to alcohol and propyne The mixture of CO2 +H2O and H2 is passed over Ru:Mn:Ni nano catalyst dispersed on a high surface area antase titanium dioxide catalyst support at 773 K and at atmospheric pressure with the gas space velocity of 6000-7000/h. The catalytic reaction produces ethanol and propyne. The catalyst simultaneously splits water into hydrogen and oxygen, and carbon dioxide into carbon and oxygen under very mild reaction conditions and at atmospheric pressure. The oxygen generated during the reaction not only generates considerable amount of energy for the reaction to proceed but also sustains the oxidation states of Ru, Mn and Ni, a key step in the process.

Bidirectional Activity-Dependent Plasticity at Corticostriatal Synapses (2005)

Corticostriatal projections originate from the entire cerebral cortex and provide the major source of glutamatergic inputs to the basal ganglia. Despite the importance of corticostriatal connections in sensorimotor learning and cognitive functions, plasticity forms at these synapses remain strongly debated. Using a corticostriatal slice preserving the connections between the somatosensory cortex and the target striatal cells, we report the induction of both non-Hebbian and Hebbian forms of long-term potentiation (LTP) and long-term depression (LTD) on striatal output neurons (SONs). LTP and LTD can be induced selectively by different stimulation patterns (high-frequency trains vs low-frequency pulses) and were evoked with similar efficiency in non-Hebbian and Hebbian modes. Combination of LTP-LTD and LTD-LTP sequences revealed that bidirectional plasticity occurs at the same SONs and provides efficient homeostatic mechanisms leading to a resetting of corticostriatal synapses avoiding synaptic saturation. The effect of temporal relationship between cortical stimulation and SON activity was assessed using spike-timing-dependent plasticity (STDP) protocols. An LTP was observed when an action potential was triggered in the striatal neuron before the cortical stimulus, and, conversely, an LTD was induced when the striatal neuron discharge was triggered after the cortical stimulation. Such STDP was reversed when compared with those described so far in other mammalian brain structures. This mechanism may be essential for the role of the striatum in learning of motor sequences in which sensory and motor events are associated in a precise time sequence.
Facile Synthesis of Aryl- and Alkyl-bis(trifluoromethylsulfonyl)methanes (2005)

Abstract Various arylbis(trifluoromethylsulfonyl)methanes (1) have been synthesized by reacting the corresponding benzylic halides with sodium trifluoromethanesulfinate and then with triflic anhydride. In addition, when the aryl group of 1 is a pentafluorophenyl group, the nucleophilic para-substitution of the aryl group with alkyllithiums and sodium alkoxides occurs. This reaction is useful for the design of new Brønsted acids.
Spreading of submarine slopes caused by trenching (1977)

Abstract Submarine trenching for pipeline installation in potentially unstable sediments has recently been of increasing concern. Although typical pipeline depths are less than 3 or 4 m, trenching operations generally cause local stress concentrations within the sediments and induce excess pore pressures. The result of these stress concentrations and pore pressure increases may be spreading of submarine slumps that can endanger pipelines or other nearby installations. A simplified analytical approach is described to estimate the extent of slump spreading caused by trenching. It is shown that the spreading potential is affected by many geotechnical characteristics of the sediments in addition to geomorphic processes and the oceanographic regimes governing the area. The primary geotechnical factors that influence spreading include the porepressure parameter Af , the degree of consolidation, the coefficient of earth pressure at rest, and the strength characteristics of the soil. Dimensionless parameters are developed to illustrate graphically the functional relationships among these parameters. A Gulf of Mexico soil profile is used to quantify the spreading phenomenon.

Quantitative evaluation of a portal film contrast enhancement technique (1987)

A study was conducted to evaluate the subjective improvement in portal film image quality resulting from the contact copy contrast enhancement technique which was introduced six years ago. Five observers were asked to identify and orient polyvinyl chloride cylinder images on both original and contrast-enhanced portal films taken with a 10-MeV linear accelerator. Fixed reviewing periods (T) were alloted of 20, 40, and 60 s as well as unlimited viewing time in order to increase the clinical relevance of this comparison. A scoring system and a probability representation were used to compare the original and enhanced films as a function of T. The results show a substantial increase in object detectability for the enhanced films at the short viewing times (T = 20, 40, and 60 s). For longer times (T greater than or equal to 80 s) the object detectability for enhanced and original films is not statistically different.
