BiCMOS at low supply voltage

The effect of scaling device feature size on MOS and bipolar device performance is reviewed. Scaling power supply with proper device scaling is discussed. It is shown that conventional BiCMOS circuit operates faster than CMOS down to 3 V power supply. In the range 3 V to 2 V BiNMOS and QCBiCMOS circuits demonstrate superior performance particularly the latter. For sub-2 V operation, circuit configuration based on the saturation of the bipolar transistors showed good performance, but still many new configurations must be investigated.
Tracking performance of a broadband tapped delay line adaptive array using the LMS algorithm

The paper investigates the behaviour of a two-element broadband tapped delay line power inversion array using the LMS algorithm when it is tracking a moving jammer rotating about the array around a certain mean position. From a first-order analysis, approximate expressions for the eigenvalues, eigenvectors and the optimal weight vector are obtained. The tracking behaviour of the array is then analysed and studied, leading to the derivation of the average critical speed of the jammer beyond which array performance deterioration will start to occur. Simulation results are also presented to demonstrate the applicability of the theoretical deviations.

Analysis of the contribution of imported and locally manufactured cement to the growth of gross domestic product (GDP) of Nigeria (1986 2011)

This study attempted to examine the trends of supply and consumption of cement in Nigeria with a view to assessing the prospects of the shift of emphasis from cement import to local cement production and its effect on the economy. Data were generated through the secondary sources and Ordinary Least Squares (OLS) used to fit the models. The adequacy of the fitted models was tested using Augmented Dickey Fuller tool. The study noted that Nigeria is abundantly endowed with the basic inputs into cement manufactured with the exception of gypsum which occurs in thin-vein layers. The study revealed that the demand for cement in Nigeria is derived from the demand for residential and non-residential construction and that residential housing is by far the largest segment of cement consumption. The study also revealed that both locally manufactured cement and imported cement contributed positively to the Gross Domestic Product. This study has suggested the strategies and measures that Nigeria needs to put in place so as to become self sufficient and exporter of cement. The backward integration policy of Government will be a veritable tool for harnessing comparative strength in the production of cement in order to stimulate growth in the industry. This, however, depends on Government being able to address the issues of policy inconsistency, high energy cost, high cost of electricity and detrimental approach to deregulation. Key words: Cement supply and consumption, imported cement, local cement, Nigerian economy, backward integration policy.

It belongs in section Dionysiopsis and is similar to D. oreodoxa Bornm. but differs in, for example, its sparsely glandular hairy or almost glabrous corolla with emarginated lobes (densely non-glandular pubescent with entire lobes in D. oreodoxa). Dionysia jamzadiae is known from two places and is quite abundant at the type locality.
Utilizing reclassification to explore characteristics and prognosis of KDIGOSCr AKI subgroups: a retrospective analysis of a multicenter prospective cohort study

Abstract Background Acute kidney injury (AKI) is widespread in the intensive care unit (ICU) and affects patient prognosis. According to Kidney Disease: Improving Global Outcomes (KDIGO) guidelines, the absolute and relative increases of serum creatinine (Scr) are classified into the same stage. Whether the prognosis of the two types of patients is similar in the ICU remains unclear. Methods According to the absolute and relative increase of Scr, AKI stage 1 and stage 3 patients were divided into stage 1a and 1b, stage 3a and 3b groups, respectively. Their demographics, laboratory results, clinical characteristics, and outcomes were analyzed retrospectively. Results Of the 345 eligible cases, we analyzed stage 1 because stage 3a group had only one patient. Using 53 or 61.88 µmol/L as the reference Scr (Scrref), no significant differences were observed in ICU mortality (P53 =0.076, P61.88 =0.070) or renal replacement therapy (RRT) ratio, (P53 =0.356, P61.88 =0.471) between stage 1a and 1b, but stage 1b had longer ICU length of stay (LOS) than stage 1a (P53 <0.001, P61.88 =0.032). In the Kaplan-Meier survival analysis, no differences were observed in ICU mortality between stage 1a and 1b (P53 =0.378, P61.88 =0.255). In a multivariate analysis, respiratory failure [HR = 4.462 (95% CI 1.144–17.401), p = 0.031] and vasoactive drug therapy [HR = 4.023 (95% CI 1.584–10.216), p = 0.003] were found to be independently associated with increased risk of death. Conclusion ICU LOS benefit was more prominent in KDIGOSCr AKI stage 1a patients than in stage 1 b. Further prospective studies with a larger sample size are necessary to confirm the effectiveness of reclassification.
Nonlinear optic polymer core conductive-polymer-clad optoelectronic device

A scheme for a five volt V(pi) ) nonlinear optical (NLO) polymer optoelectronic (OE) device is presented with the potential to realize an interaction length that is about an order of magnitude shorter than conventional five volt V(pi) ) NLO polymer OE devices. It utilizes available NLO polymer materials for the core layer and a conductive polymer material for the cladding layers. Since the cladding layer material is more conductive than the core material, most of the applied poling and modulation voltages is dropped across the core layer, rendering a more efficient device. Using an NLO polymer material with electrooptic (EO) coefficients of say 22 pm/V, it is feasible to demonstrate < 2 mm OE devices operating at TTL voltage levels. These small device sizes could lead to use within electronic multichip modules. In addition, since the majority of the poling voltage is dropped across the core layer, less voltage is required so that in-situ poling becomes possible.
Communication Quality-Conscious Synthesis of 3-D Coverage Using Switched Multibeam Multi-Sector Array Antenna for V2I Application

In this paper, a switched multibeam multi-sector array antenna is proposed to provide 3-D coverage for vehicle to infrastructure (V2I) under 5G-IoT application framework. The multi-sector design is optimized using a quality-conscious communication area synthesis process to achieve <inline-formula><tex-math notation="LaTeX">$\mathbf {360}^\circ$</tex-math></inline-formula> coverage in azimuth. Each sector of the design has two microstrip array antenna (MAA) to obtain coverage in the upper and lower halves of the elevation region. The proposed antenna is designed to enhance frequency-dependent beam squint phenomena exploited to achieve multibeam coverage in the elevation region. The simulation results of the proposed antenna having <inline-formula><tex-math notation="LaTeX">$\mathbf {3\times 2}$</tex-math></inline-formula> size of MAA indicates the achieved desired radiation characteristics, and a prototype of the same operating in WLAN band (<inline-formula><tex-math notation="LaTeX">$\mathbf {5.15-5.825}$</tex-math></inline-formula> GHz) is fabricated for verification. The experimental results show the maximum realized gain is <inline-formula><tex-math notation="LaTeX">$\mathbf {7.85}$</tex-math></inline-formula> dBi and the beam tilt of <inline-formula><tex-math notation="LaTeX">$\mathbf {10.8}^\circ$</tex-math></inline-formula> to <inline-formula><tex-math notation="LaTeX">$\mathbf {46.8}^\circ$</tex-math></inline-formula> in elevation is achieved at central frequencies <inline-formula><tex-math notation="LaTeX">$\mathbf {5.15}$</tex-math></inline-formula> GHz and <inline-formula><tex-math notation="LaTeX">$\mathbf {5.825}$</tex-math></inline-formula> GHz, respectively. The coverage obtained is <inline-formula><tex-math notation="LaTeX">$\mathbf {360}^\circ$</tex-math></inline-formula> in azimuth and <inline-formula><tex-math notation="LaTeX">$\mathbf {93.6}^\circ$</tex-math></inline-formula> in elevation. The signal to interference ratio is measured around the antenna, which shows interference suppression of more than <inline-formula><tex-math notation="LaTeX">$\mathbf {10}$</tex-math></inline-formula> dB achieved between the MAAs of alternate sectors. Moreover, the port isolation is better than <inline-formula><tex-math notation="LaTeX">$\mathbf {26}$</tex-math></inline-formula> dB. Hence, sixteen simultaneous beams utilizing frequency re-use can be operated in the 3-D space around the access point to communicate with multiple drones/vehicles and IoT nodes to realize a smart vehicular application.
Keys to Successful Utility Coordination

One of the greatest potential hazards and liabilities in pipeline design and construction is related to utility crossings. Pipeline projects may encounter crossings with electrical, fiber optic, natural gas, and a host of other utilities. When poorly identified, each utility crossing poses a liability to engineers and a threat to the safety of contractors. Although this thesis is well established by case history, steps may be taken to avoid new utility related construction disasters. This paper discusses case histories that teach the importance of utility coordination, the identifying of utility conflicts, designing around conflicts, communicating with field crews and contractors, and keys to successful utility coordination.
Analysis on Cogging Torque of Permanent Magnet Synchronous Motor for NC Machine Tool Servo-System

This paper presents a procedure of calculating cogging torque of Permanent Magnet Synchronous Motor (PMSM) for NC machine tool servo-system based on finite element method (FEM). Simulation models of PMSM are established to complete coupled calculation between magnetic fields and mechanical dynamics. Furthermore, the distributions of magnetic flux and electromagnetic force densities are also gained. Finally, the cogging torque of the motor in operating process is suppressed by changing slot opening configuration. The references for the optimization design on NC machine tool servo-system are provided by the simulation model.
Engineering of a trispecific tumor-targeted immunotherapy incorporating 4-1BB co-stimulation and PD-L1 blockade

ABSTRACT Co-stimulatory 4–1BB receptors on tumor-infiltrating T cells are a compelling target for overcoming resistance to immune checkpoint inhibitors, but initial clinical studies of 4–1BB agonist mAbs were accompanied by liver toxicity. We sought to engineer a tri-specific antibody-based molecule that stimulates intratumoral 4–1BB and blocks PD-L1/PD-1 signaling without systemic toxicity and with clinically favorable pharmacokinetics. Recombinant fusion proteins were constructed using scMATCH3 technology and humanized antibody single-chain variable fragments against PD-L1, 4–1BB, and human serum albumin. Paratope affinities were optimized using single amino acid substitutions, leading to design of the drug candidate NM21-1480. Multiple in vitro experiments evaluated pharmacodynamic properties of NM21-1480, and syngeneic mouse tumor models assessed antitumor efficacy and safety of murine analogues. A GLP multiple-dose toxicology study evaluated its safety in non-human primates. NM21-1480 inhibited PD-L1/PD-1 signaling with a potency similar to avelumab, and it potently stimulated 4–1BB signaling only in the presence of PD-L1, while exhibiting an EC50 that was largely independent of PD-L1 density. NM21-1480 exhibited high efficacy for co-activation of pre-stimulated T cells and dendritic cells. In xenograft models in syngeneic mice, NM21-1480 induced tumor regression and tumor infiltration of T cells without causing systemic T-cell activation. A GLP toxicology study revealed no evidence of liver toxicity at doses up to 140 mg/kg, and pharmacokinetic studies in non-human primates suggested a plasma half-life in humans of up to 2 weeks. NM21-1480 has the potential to overcome checkpoint resistance by co-activating tumor-infiltrating lymphocytes without liver toxicity.
HBT's RF noise parameter determination by means of an efficient method based on noise analysis of linear amplifier networks

A method for the evaluation of the RF noise figure of heterojunction bipolar transistors (HBTs) is presented. The noise analysis is based on the use of the correlation matrices. The two-port device is described as an interconnection of basic two-port devices whose noise behaviour is known. The circuit theory of linear noisy networks allows that any two-port device can be replaced by a noise equivalent circuit which consists of the original two-port assumed to be noiseless and possess two additional noise sources. The purpose of this paper is to obtain the four noise parameters of the device, taking into account the excess resistances and inductances. The calculations presented show good agreement with measurements, and as a consequence, they permit a good estimation of the noise performance of the structure without neglecting any parasitic elements of the equivalent circuit.
Simplified Multimodal Biometric Identification

Multibiometric systems are expected to be more reliable than unimodal biometric systems for personal identification due to the presence of multiple, fairly independent pieces of evidence e.g. Unique Identification Project "Aadhaar" of Government of India. In this paper, we present a novel wavelet based technique to perform fusion at the feature level and score level by considering two biometric modalities, face and fingerprint. The results indicate that the proposed technique can lead to substantial improvement in multimodal matching performance. The proposed technique is simple because of no preprocessing of raw biometric traits as well as no feature and score normalization.
Non-superconducting fault current limiters

This paper proposes the use of non-superconducting DC reactor type fault current limiter (NSFCL) instead of superconducting fault current limiters (SFCLs) which has high cost and technology. Proposed FCL consists of three similar sets, each including a diode bridge and a single non-superconducting DC reactor. The device is connected in series with distribution line and it has almost no effect on the normal system operation. It is not necessary to use a control circuit and it has a simple and cheap power circuit. Design characteristics, analytical analysis and overall transient and steady-state performance of NSFCL in normal and fault conditions are presented in this paper. The comparison between experimental and simulation results indicate good agreements. The results confirm that the power loss of NSFCL is a very small percentage of distribution line power. Also, the system current and load voltage distortions due to using NSFCL is explained and simulated. Copyright © 2008 John Wiley & Sons, Ltd.
DLW-Net model for traffic flow prediction under adverse weather

To predict traffic flow under adverse weather, a hybrid deep learning model concerning adverse weather (DLW-Net) is formulated. The DLW-Net model consists of the target and global analysis parts. For the target analysis part, the spatio-temporal characteristics of traffic flow data are analyzed using the convolutional neural network (CNN), the long short-term memory (LSTM) and gated recurrent unit (GRU) neural networks. For the global analysis part, the variation rules of traffic flow and weather data are extracted using the LSTM model. Additionally, the characteristics of traffic flow under normal and adverse weather are also discussed. The developed model is verified using three cases. The results show that traffic volume and speed would reduce under heavy rain compared to normal weather, however, drizzle has little impact on traffic flow patterns; the rules of traffic speed data are disturbed by strong wind; and the DLW-Net model performs best under all the conditions.
Making Sense of Rich Pictures: Combining SSM and Oval Mapping

This paper describes the use of Oval Mapping Technique (OMY) to combine the insights gained from multiple research sites by a team of researchers drawn from three universities and represented through Soft Systems Methodology rich pictures. The research team were confronted with the problem of how to develop a shared and comprehensive view of the research arena, which was how to gain and apply knowledge about sustainable construction methods. Through the use of OMT the team assembled clusters of related concepts which formed the basis of CATWOEs and root definitions. Further, they overcame their problems that arose from the absence of a problem owner who could verify and legitimate their reading of world. The C-SanD 1 project committed itself to structure its investigation around Soft System Methodology. The nature of the project, however, has required constant reflection on the SSM process; taking seriously Checkland’s injunction that SSM in mode 2 is not a series of steps and techniques but a methodology for “reflection upon the everyday flux of events and ideas using SSM to make sense of it”; and building upon the seven stages and where the area of application is the learning of the actors (Checkland and Scholes, 1990 p 284). By treating the methodology in this way, “every use of it will potentially yield methodological lessons” (p287). SSM as an action research technique is typically aimed at addressing a problem situation in a more or less specific organizational context. C-SanD is, by contrast, seeking to learn from specific instantiations of issues in diverse contexts to design generic systems that will have wide applicability across the construction industry, while realising that the re-introduction of systems and tools based upon this analysis into specific organizational contexts will itself be problematic. Understanding, designing and managing this implementation process will require further exploration, using SSM. The first stage interviews consisted of 16 interviews with representatives of 10 organizations undertaken by four researchers from three universities. These interviews generated over 500 pages of interview transcripts. Given the time constraints on the project, a method was required which would allow each of the researchers to reach a rich understanding of the issues arising from all the interviews without requiring each of them to express each interview as a rich picture. The intention was to outline the following: • key issues associated with the project;
Constructing input vectors to neural networks for structural damage identification

This paper addresses construction of appropriate input vectors (input patterns) to neural networks for hierarchical identification of structural damage location and extent from measured modal properties. Hierarchical use of neural networks is feasible for damage detection of large-scale civil structures such as cable-supported bridges and tall buildings. The neural network is first trained using one-level damage samples to locate the position of damage. After the damage location is determined, the network is re-trained by an incremental weight update method using additional samples corresponding to different damage degrees but only at the identified location. The re-trained network offers an accurate evaluation of the damage extent. The input vectors have been designed to meet two requirements: (i) most parameters of the input vectors are arguably independent of damage extent and only depend on damage location; (ii) all parameters of the input vectors can be computed from several natural frequencies and a few incomplete modal vectors. The damage detection capacity of such constructed networks is experimentally verified on a steel frame with extent-unknown damage inflicted at its connections, and the applicability of the hierarchical identification strategy to cable-supported bridges is discussed.
The King is Naked – a very subjective look at child and adolescent psychiatry

For quite some time now an increasing number of voices can be heard in the public space regarding the decline of child and adolescent psychiatry: shortage of specialists, shortage of hospital wards and permanently insufficient financial support of this branch of medicine. However, in all the media hum about this problem and in the debates about how to solve it. are we not losing sight of its essence?
Does gender moderate effects of religion on anxiety among Orthodox and non-Orthodox Jews?

ABSTRACT Studies examining religion's effects on mental health have insufficiently focused on basic moderators of observed effects. Given that Orthodox Jewish religious culture places greater ritual obligations on men than women, but is gender-equivalent regarding faith, we expected Orthodox Jewish men and women to experience different levels of anxiety in relation to religious practice but not intrinsic religiosity, and that no gender differences would exist among non-Orthodox Jews. In a community sample of 414 Jewish adults (51% Orthodox), religious practice differed predictably based on denomination and gender norms, and intrinsic religiosity was higher for Orthodox Jews. Both practice and intrinsic religiosity were associated with less anxiety overall. However, contrary to expectations, there were no interactions with gender. These results suggest that the effects of Jewish religious observance and belief on anxiety may not be gender-specific, even within communities that ascribe to more traditional religious values and gender roles.
An activist investor’s successful corporate governance and strategic management impacts: An updated L Brands case study

The key research aim of this paper is to analyze whether an activist investor’s recommendations for financial, corporate governance, and strategic management performances were successful or not. This paper updates the initial case study of the activist investor, Barington Capital Group, in analyzing the performance of a public company, L Brands, which had lost $20 billion in market capitalization in the last three years prior to the public letter from Barington to the L Brands CEO in March 2019. This updated case study analyzes whether Barington’s initial recommendations worked as operational guidelines for improving L Brands’ financial, corporate governance, and strategic management performances. From its financial analysis, Barington recommended either an initial public offering of the superior performing Bath & Body Works brand or a spinoff of the weak performing Victoria’s Secret brand. From its corporate governance and strategic management analysis, Barington recommended that L Brands improve the composition of its board of directors whose deficiencies in director independence, industry experience, and diversity hindered its ability to effectively oversee and advise strategic management. It is important to note that this paper was prepared exclusively with public information.
